Description

Technical Field

[0001] This utility model belongs to the field of air purifier technology, and in particular relates to an air purifier that can solve the problem of residual smoke smell. Background Technology

[0002] Air purifiers, as guardians of health in modern homes and offices, are increasingly valued and favored. Through their built-in multi-layer high-efficiency filtration system, such as a pre-filter to intercept large particles, a HEPA filter to capture dust, pollen, smoke, and some bacteria and viruses as small as 0.3 microns, and an activated carbon layer to powerfully adsorb harmful gases and odors like formaldehyde and benzene, they comprehensively purify indoor air, creating a fresh and healthy breathing space for users.

[0003] Smoke contains numerous small organic compounds, volatile organic compounds, and harmful substances such as nicotine. Due to their tiny molecular size and unique chemical properties, current air purifiers on the market are ineffective at removing smoky environments and struggle to completely eliminate residual smoke odors.

[0004] Air purifiers primarily rely on filters to capture airborne pollutants. However, for the small molecules in smoke, the filter is like a mesh that isn't fine enough, making it difficult to intercept them all. While HEPA filters are effective at filtering larger pollutants, their efficiency is significantly reduced when faced with the tiny molecules in smoke. Activated carbon filters can adsorb some harmful gases, but their adsorption capacity for the diverse organic compounds and volatile organic compounds in smoke is limited. This results in air purifiers leaving a lingering, difficult-to-remove smoky smell, silently testifying to the less-than-ideal purification effect.

[0005] Even more problematic is that when the air purifier is turned on again, the smoke particles adsorbed on the HEPA filter, like "sleepers" awakened, are released back into the air, further amplifying the concentration and range of the smoke smell. The smoke smell, which was not completely eliminated to begin with, becomes even more intense due to these re-released particles, making people feel as if they are in a smoke-filled "dilemma," making it difficult to breathe.

[0006] One of the Chinese patents relates to a desktop air purifier for smoke removal, disinfection, and sterilization (CN210057642U). It includes a chassis with a welding assembly consisting of a soldering iron holder and a solder wire holder mounted on the outside. An air inlet is located on one side of the chassis, and an air intake assembly facing the inlet is located inside the chassis. The air intake assembly is situated in an independent air box and connected to an upper air duct. The air duct connects to a disinfection and purification chamber inside the chassis. The disinfection and purification chamber contains a multi-stage filtration and disinfection device. This purifier filters and disinfects the toxic and harmful fumes generated by the solder wire, producing relatively clean and fresh air, protecting the physical and mental health of workers. Furthermore, it integrates the solder wire holder and soldering iron holder into one compact unit, making it easy to assemble and disassemble. The filter element is easy to replace, allowing for direct use at the welding site without the need for additional or assembled welding air purification devices, thus facilitating welding work. This utility model has a simple structure, strong practicality, and is easy to use and promote.

[0007] A Chinese patent for a miniature plasma dynamic air purifier (CN214223351U) mainly includes a fan, a plasma generator, an electronic air filter, and a control circuit. The fan introduces outside air into the purifier to form an air duct. The air is purified by the electronic air filter and the plasma generator, generating a large amount of plasma. The control circuit includes at least two control units, each generating a DC high voltage of over 6000V to supply the electronic air filter and the plasma generator respectively. It can also control the pulse control signals of the fan and the plasma generator according to the outside air quality to better purify the air. This purifier can effectively purify the air and disinfect viruses. The entire device has a compact structure, achieving miniaturization and lightweight design, which is conducive to large-scale production and application.

[0008] Chinese patent CN1 10671759A describes an odor removal device for air purifiers. Its structure includes a base, air inlet, body, top cover, air outlet, negative ion device, and odor removal device. The bottom of the body is connected to the base, and the top cover is installed on the top of the body. The top cover has an air outlet, and a negative ion device is installed at the air outlet. The odor removal device is located inside the body and below the air outlet. The odor removal device includes a candle, a fixing device, a housing, a flameout device, and an ignition device. The housing is fixed inside the body, and the candle is located in the middle of the housing. Fixing devices are located on both sides of the candle, and a flameout device is located above the fixing devices. The beneficial effect of this invention is that by adding a candle-lighting device to the air purifier, the amorphous carbon produced by the burning candle enters the kitchen air along with the purified air. While exchanging air, the amorphous carbon dispersed in the air is adsorbed, improving smoke removal efficiency and resulting in better air quality in the kitchen.

[0009] A Chinese patent for a high-pressure smoke air purifier (CN1 01954111B) includes a housing with an air inlet and an air outlet, a dual negative electrode high-voltage grid, a high-voltage generator, a programmable controller, a fan, and a power supply. The dual negative electrode high-voltage grid includes an aluminum-magnesium-zinc alloy microporous mesh and an aluminum-magnesium-zinc alloy corrugated mesh serving as negative electrodes, and a positive electrode discharge grid disposed between the aluminum-magnesium-zinc alloy microporous mesh and the aluminum-magnesium-zinc alloy corrugated mesh. The high-voltage generator includes a first DC voltage regulator circuit for rectification and filtering, an oscillation control circuit for generating oscillation control signals, a humidity control circuit for generating control signals based on air humidity, and a boost circuit. This high-pressure smoke air purifier eliminates the need for filters, overcoming the secondary pollution caused by filters in air filtration in existing technologies, as well as the inconvenience of regularly cleaning filters. It purifies the air by generating negative oxygen ions through high-voltage discharge and rapidly eliminates smoke, harmful substances, and harmful bacteria in the air through corona discharge.

[0010] However, none of the above patents have been able to effectively solve the problem of smoke, and it is difficult to completely remove the residual smoke smell. Utility Model Content

[0057] The purification component 5 is installed on the middle frame 4. The front cover 1 and the rear cover 3 are provided with air outlet covers 6 at the top and connected to the base 23 at the bottom.

[0058] A water tank 7 is connected to one side of the purification component 5, which introduces filtered air into the water tank 7.

[0059] The purification component 5 includes an air filter 51, a HEPA filter 52, a motor impeller assembly 53, and an air duct cover 54. The middle frame 4 is provided with a mounting groove 24. The air filter 51 and the HEPA filter 52 are installed in the mounting groove 24 in sequence. The motor impeller assembly 53 is installed in the air duct cover 54.
