Vacuum cleaner solution
Brooms, brooms, mops and other cleaning tools are the earliest traditional tools for household cleaning, but these traditional methods have never met the goal of people's convenient life. In order to meet people's needs, smarter and more convenient life products have appeared, so modern Smart products such as vacuum cleaners and sweeping robots have appeared on the market. From ancient times to the present, cleaning tools have a history of more than 4,000 years. The invention of the broom originated in China and played a decisive role in the cleanliness and healthy living of the Chinese people. The earliest vacuum cleaner was invented in 1860, and it has a history of more than 150 years. The vacuum cleaner at that time was just a carpet cleaner, not the current vacuum cleaner. The subsequent development of vacuum cleaners.
When buying a vacuum cleaner, you should know what it does and what it can do. Vacuum cleaners are for vacuuming, no doubt about it. Cleaning the dust in the corners is its specialty. However, vacuum cleaners are more suitable for cleaning floating dust. For wet surfaces or dirt that has adhered to the surface of objects, the effect of vacuum cleaners is not as good as that of mops and rags (some export products are wet and dry, and their power and air volume are quite large. ). A vacuum cleaner with a roller brush is better for cleaning the dust on the carpet.
1. The technical principle of the vacuum cleaner solution
The motor of the vacuum cleaner rotates at high speed, sucking in air from the suction port, so that the dust box generates a certain vacuum, and the dust enters the dust filter bag in the dust box through the floor brush, connecting pipe, handle, hose, and main suction pipe, and the dust is left in the dust filter bag, filtered The final air enters the motor through a layer of filter. This filter is a protective barrier to prevent the dust bag from being broken and sucked into the motor. Added another filter before.
The finer the filter material, the cleaner the air can be filtered, but the poorer the air permeability, which affects the air volume sucked by the motor and reduces the efficiency of the vacuum cleaner. But for users, comfort and cleanliness is the main thing. Its air permeability is low, so it is made into waves to increase the air permeability area. Some of this filter material can also be washed repeatedly. Any filter material has a "lifespan", that is, the micropores of the filter material have been blocked by small particles of dust after long-term use.
Vacuum cleaners are mainly composed of three parts: dust collection, dust collection, and dust filtration, generally including series commutator motors, centrifugal fans, dust filters (bags) and dust collection accessories. Generally, the power of vacuum cleaners is 400-1000W or higher, and the power of portable vacuum cleaners is generally 250W or less. The vacuum cleaner can remove dust mainly because its "head" is equipped with an electric exhaust fan. There is a wind impeller on the shaft of the exhaust fan. After power on, the exhaust fan will generate high suction and pressure at a speed of 500 cycles per second. The air in the fan is replenished in a timely manner, resulting in an instantaneous vacuum inside the vacuum cleaner, forming a negative pressure difference with the external atmospheric pressure, and under the action of this pressure difference, the dust-containing air is sucked in. Dust and other sundries enter the dust filter bag through the carpet or floor brush, long pipes, elbows, hoses, and hose joints in turn. Dust and other sundries stay in the dust filter bag.
2.The important performance indicators of the vacuum cleaner
Generally speaking, whether at home or abroad, vacuum cleaners have an important reference index—power. But purely in terms of power, it has no more special meaning than representing power consumption. But for a vacuum cleaner, the meaning of power is an important parameter representing the performance of a machine. It can be said that the power of the vacuum cleaner determines the performance of the vacuum cleaner. The more powerful the machine in the vacuum cleaner, the stronger the suction. But there are exceptions, that is, the sealing of the machine is not good, and the air is deliberately vented to reduce the temperature rise, and the low-efficiency motor may also cause high power and low suction. The really important indicators for vacuum cleaners should be suction power, vacuum degree, air volume (air flow rate), and noise.
Vacuum degree: an important indicator of the suction force. This indicator also has a lot to do with power. Generally, the higher the power, the higher the index should be. Taking 1000W as the standard, the value should be around 20kPa.
Air volume: the air flow through the suction port of the vacuum cleaner per unit time. An indicator that is as important as vacuum is also related to power. Taking 1000W as the standard, the value should be around 18L/s.
Noise: The noise of a vacuum cleaner of about 1000W is generally about 80dB. The lowest noise is the rechargeable vacuum cleaner, the noise of the high-end is only 40dB, but the power is only a pitiful 350W.
Temperature: For a 1000W vacuum cleaner, after a long time of operation, the temperature of the air outlet is generally above 40°C. Similarly, the lower the power, the lower the temperature rise. At present, the vacuum cleaners produced by major manufacturers have passed the CCC safety certification. The certification includes a temperature rise test. Therefore, although high-power vacuum cleaners are hot spots, they still meet safety regulations.
3. Types of vacuum cleaner solutions
Brooms, brooms, mops and other cleaning tools are the earliest traditional tools for household cleaning, but these traditional methods have never met the goal of people's convenient life. In order to meet people's needs, smarter and more convenient life products have appeared, so modern Smart products such as vacuum cleaners and sweeping robots have appeared on the market. From ancient times to the present, cleaning tools have a history of more than 4,000 years. The invention of the broom originated in China and played a decisive role in the cleanliness and healthy living of the Chinese people. The earliest vacuum cleaner was invented in 1860, and it has a history of more than 150 years. The vacuum cleaner at that time was just a carpet cleaner, not the current vacuum cleaner. The subsequent development of vacuum cleaners.
Compared with a manual tool like a broom, which sweeps dust all over the sky, the birth of a vacuum cleaner can not only clean and remove dust, but also absorb various harmful substances and bacteria in the air. It is a healthier and more meticulous cleaning tool. With the improvement of people's quality of life, vacuum cleaners gradually replace brooms as the future household cleaning tool, and it is also the future trend of just-needed appliances. In addition to large-scale outdoor vacuum cleaners, there are also many types of cleaning appliances for household indoor vacuum cleaners.
1. Intelligent sweeping robot
Automatically clean the dust on the floor, automatically clean up hair and debris, and automatically return to charge after the cleaning task is completed. The core technology of the smart vacuum cleaner is the chip and the software inside. A high-end vacuum cleaner that can automatically clean and charge. The advantages are low noise, small size, and easy access to places that traditional vacuum cleaners cannot reach.
2. Central vacuum system
For high-end vacuum cleaners, it is a place where the main unit of the vacuum cleaner is placed outside the main living area, such as: underground equipment floors, garages, cleaning rooms, etc., and the vacuum pipes are embedded in the wall, leaving only small and beautiful vacuum cleaners on the wall. When it needs to be cleaned, you only need to insert a hose into the suction port. At this time, the system will automatically start the host switch, and all dust, paper scraps, cigarette butts, harmful microorganisms, and even bad smells such as smoke in the guest room will It is transported to the central collection station through strictly sealed pipelines. Full or partial cleaning can be performed by anyone at any time, ensuring the cleanest indoor environment. Its cleaning capacity is 5 times that of ordinary vacuum cleaners, and the length of the hose can be optional. This type of system has become a must-have system in European and American countries, and some high-end real estate in China have adopted this advanced technology.
3. Water filter vacuum cleaner
The water filter vacuum cleaner uses water as the filter medium to dissolve and lock various microorganisms such as dust, garbage and bacteria in the water when they are sucked through the water tank by strong suction. Use water to wet the dust to avoid the overflow of fine dust during vacuuming; use water to purify the inhaled gas and dissolve allergens, bacteria and other microorganisms. Then, it is further filtered through HEPA, high-efficiency filter cotton, etc., and these three purification systems ensure the perfect and efficient water filtration. The water filtration technology was originally developed for people who are prone to allergies. It dissolves and locks dust, particles, allergens, pollen, dust mites, and small bacteria through water to avoid allergies caused by unclean air during the vacuuming process.
4. Portable mini vacuum cleaner
The portable mini vacuum cleaner is lightweight and flexible, with a convenient lift design, just pick it up and press it lightly with your hand, and you can easily vacuum. The sling design allows you to carry it around your waist for operation. Use a large suction head to suck anything on the ground (except water), use a wide-head suction head to suck up items with gaps (the wide-head suction head has a bristle brush, which can clean the dust in the gap), use a hose You can carry it on your back when vacuuming. It can not only absorb sofas, curtains, but also dust from ceilings, computer keyboards, bed surfaces and the surfaces of various household appliances. Equipped with a small square brush that can be turned, it can be used to remove dust from computer keyboards, clean up small-scale debris and vacuum pets, clean up the dirt hidden in every dead corner and crevice, improve cleaning efficiency, and be more convenient to use.
5. Mite removal vacuum cleaner
As the name suggests, the main function of the mite-removing vacuum cleaner is to remove and kill mites. Medical-grade ultraviolet lamps can remove mites and bacteria on beds, sofas, bath towels, baby crawling blankets, plush toys, and other household items. The 400W suction can completely eradicate the living environment of mites and can suck away the infectious body of mites.
4. The brand of the vacuum cleaner
More than 70% of the world's vacuum cleaners are produced in China. Brands sold in China, such as Philips, Electrolux, Panasonic, Sanyo, LG, Haier, Midea, etc. are all domestically produced products, while brands sold abroad, such as HOOVER ROYAL, EUROPRO, WAL-MART, etc., are mostly The products are all OEM in China. More than 70% of the vacuum cleaners produced in China are for export, which also shows that domestic manufacturers can produce good products, but the best products are not sold domestically, and most of them are sold to Japan, Europe and the United States and other countries. The production volume of domestic manufacturers is very large, with the largest annual output reaching 1 million units. Therefore, when purchasing household vacuum cleaners, consumers should not only pay attention to the brand, but also consider the specific technology, functions, parameters, indicators, etc. of the product, and conduct multi-faceted comparisons.
5. Suggestions for purchasing vacuum cleaner brands
The connection of each part of the vacuum cleaner should be tight. If it is a plastic body, consumers should check whether there are cracks in the body and whether the connection between the cylinders is tight; seal. After checking the surface, turn on the vacuum cleaner and you will hear the sound of suction. At this time, you can approach the joint with your hand. If you can’t feel the airflow, it means that the sealing performance is good. Otherwise, it will not only waste electricity, but also cause secondary pollution.
For a high-performance vacuum cleaner, strong enough suction is essential. Various suction nozzles and special-purpose accessories are indispensable to ensure the effective vacuuming of the vacuum cleaner, which can improve efficiency and enhance the cleaning effect. At the same time, consumers should pay attention to the filter system of the vacuum cleaner. Generally, the higher the filter density, the better the filter effect. Many consumers buy vacuum cleaners for use at home. They should pay special attention to the performance of the motor. You can check the smoothness of the machine's operation by connecting the power supply, and whether there are noises such as squealing or friction, so as to avoid noise and safety hazards.
Many vacuum cleaners are equipped with a thermostat for safety to ensure that after the vacuum cleaner is overheated, it will not restart even if it is connected to the power supply. However, overheating protection is not a panacea. To avoid damage to the vacuum cleaner, the filter material must be cleaned in time. . In addition, consumers must read the instructions carefully before using the vacuum cleaner they choose to avoid damage to the vacuum cleaner and endanger personal safety due to improper use.
6. Vacuum cleaner filter structure
Many vacuum cleaners now advocate HEPA filtration. Indeed, HEPA filtration efficiency is indeed relatively high, but one problem needs to be paid attention to: high filtration efficiency and fast clogging. HEPA needs to be cleaned or replaced frequently. The HEPA in the vacuum cleaner is actually a paper-based multi-layer filtration system. The nominal filtration efficiency of imported HEPA is above 99.8%, while domestic ones can only achieve above 90-95%. Domestic manufacturers also use imported HEPA, but consumers should not blindly believe in imports. Many imported HEPAs are also shoddy products. High filtration efficiency means that the PA will be clogged quickly, especially for fine ash. Dust, although HEPA can be reused after being washed and dried after clogging, but the washed HEPA is still blocked by dust due to the many pores in the paper or some pores have been destroyed due to washing, and its air intake capacity also drops quickly. After 10 uses, it will basically have no effect. If such HEPA is used for a long time, it will cause a serious decline in the performance of the vacuum cleaner. and damage the motor.
Dust bag: The most traditional filter material, distributed and paper, paper is of course disposable, cloth can be used repeatedly, but it needs to be cleaned, and SMS cloth is better. The filtration efficiency of the dust bag is medium. Generally, it can reach the level of 70% to 80%.
Filter screen: Some low-power vacuum cleaners usually use a filter screen structure, which is also the material with the lowest filtration efficiency, only about 60%, but it is the easiest to clean.
Cyclone structure: The current mainstream structure of household vacuum cleaners can rely on centrifugal force to throw dust into the dust box and reduce the burden on the filter. It has a certain effect, but it is only an auxiliary function. The filter mainly depends on the filter.
One last thing to pay attention to: no matter what kind of filter material the vacuum cleaner uses, the finer the dust it sucks, the easier the filter material will be clogged. Therefore, sometimes you can see that there is not much dust in the dust bag, but the protector operates. Don’t be surprised, it’s a normal phenomenon. At this time, it needs to be cleaned up (patted, washed).
7. The roller brush of the vacuum cleaner
The function of the roller brush of the vacuum cleaner is mainly to clean carpets and wool textile objects. Using a hard nylon bristle roller brush may damage the floor. With a lifting plate, you can lift the roller brush to avoid damaging the floor. If it is a soft bristle roller brush, it should clean the floor well.
There are two types of roller brushes: electric and pneumatic. The noise of the wind-operated roller brush is greater than that of the electric roller brush. If the wind-operated roller brush inhales foreign objects, the wind wheel may be damaged or stuck. If the powerful electric floor brush is subjected to too much pressure or resistance to cause the roller brush to stop, either the roller brush is broken or the belt is broken. The electric floor brush of a rechargeable or low-power vacuum cleaner does not have this problem, but it is easy to stop when encountering resistance. At present, there are also electric ground brushes with overload protection, that is, when the resistance is too large, the indicator light will light up and cut off the current of the ground brush.
