AI Technical Summary

Technical Problem

When existing air purifiers purify smoke smell, the filter absorbs smoke only in a limited way, making it difficult to completely remove residual smoke smell. Especially when the air purifier is restarted, the smoke particles on the HEPA filter are re-released, further expanding the concentration and range of smoke smell.

Method used

An air purifier is designed. By setting up a water tank at the bottom of the air duct cover plate, the contaminated air is passed through the initial filter of the air filter and the Hypa, and then enters the water tank, and filters through the secondary adsorption of water and smoke to remove smoke smell residue.

Benefits of technology

Effectively and thoroughly remove smoke odor residues, avoiding the re-release of smoke particles on the HEPA filter, and significantly improving the air purification effect.

Description

Technical Field

[0001] The present invention belongs to the technical field of air purifiers, and particularly relates to an air purifier that can solve the problem of residual cigarette smell. Background Art

[0002] As a health guardian in modern home and office environments, air purifiers are increasingly being valued and favored by people. It purifies indoor air in all aspects through a built-in multi-layer high-efficiency filtration system. For example, the primary filter intercepts large particles, the HEPA filter captures dust, pollen, smoke, and some bacteria and viruses as small as 0.3 microns, and is supplemented by an activated carbon layer to strongly adsorb harmful gases and odors such as formaldehyde and benzene, creating a fresh and healthy breathing space for users.

[0003] Smoke contains many harmful substances such as organic compounds with relatively small molecules, volatile organic compounds, and nicotine. Due to their small molecular size and unique chemical properties, the air purifiers currently on the market are unable to effectively purify a smoky environment and are difficult to completely remove the residual cigarette smell.

[0004] Air purifiers mainly rely on filters to capture pollutants in the air. However, for these small molecules in smoke, the filter is like a net that is not fine enough to intercept them all. Although the HEPA filter can effectively filter larger particle pollutants, its capture efficiency is greatly reduced when facing those tiny molecules in smoke. Although the activated carbon filter can adsorb some harmful gases, its adsorption capacity for the various organic compounds and volatile organic compounds in smoke is also limited. This results in the air after being processed by the air purifier still having a lingering cigarette smell, as if silently indicating the unsatisfactory purification effect.

[0005] Even more troublesome is that when the air purifier is restarted, the smoke particles adsorbed on the HEPA filter, like awakened "sleepers", are released back into the air again, further increasing the concentration and scope of the cigarette smell. The cigarette smell that was not completely removed originally becomes even stronger due to these re-released particles, making people feel as if they are in a smoky "predicament" and making it difficult to breathe.

[0006] Among them, a Chinese patent for a desktop smoking disinfection and sterilization air purifier in the field of air purification (CN210057642U) includes a chassis. A welding component including a soldering iron stand and a solder wire stand is installed on the outer side of the chassis. An air inlet is provided on one side of the chassis. An air inlet component facing the air inlet is provided inside the chassis. The air inlet component is in an independent air box and communicates with the upper air duct. The air duct communicates with the disinfection and purification chamber inside the chassis. A multi-stage filtering and disinfection device is provided in the disinfection and purification chamber. The toxic and harmful smoke generated by soldering the solder wire is filtered and disinfected by this purifier, and relatively clean and fresh air is filtered out, protecting the physical and mental health of the staff. Moreover, the solder wire stand and the soldering iron stand are integrated, the whole machine is small and compact, easy to disassemble and assemble, and the filter element is convenient to replace, facilitating direct use at the welding site without additionally installing and assembling relevant welding air purification devices, which is beneficial to the progress of welding work. The utility model has a simple structure, strong practicability, is easy to use and promote.

[0007] A Chinese patent for a micro-plasma dynamic air purifier (CN214223351U) mainly includes a fan, a plasma generator, an electronic air filter screen, and a control circuit. The fan introduces external air into the purifier to form an air duct. The gas is purified by the electronic air filter screen and the plasma generator and a large amount of plasma is generated. The control circuit includes at least two control units. Each control unit generates a DC high voltage of more than 6000V and supplies it to the electronic air filter screen and the plasma generator respectively, and can control the pulse control signals of the fan and the plasma generator according to the external air quality to better purify the air. The purifier of the present invention can effectively purify the air and kill viruses; the whole device has a compact structure, can be miniaturized and lightweight; it is beneficial to large-scale production and application.

[0008] A Chinese patent for an odor removal machine for an air purifier (CN110671759A) has a structure including a base, an air inlet, a machine body, an upper cover, an air outlet, a negative ion device, and an odor removal device. The bottom of the machine body is connected to the base. The upper cover is installed on the top of the machine body. The upper cover is provided with an air outlet, and a negative ion device is installed at the air outlet. The odor removal device is arranged inside the machine body and is located below the air outlet. The odor removal device includes a candle, a fixing device, a housing, an extinguishing device, and an ignition device. The housing is fixed inside the machine body. The candle is arranged in the middle of the housing. Fixing devices are respectively arranged on both sides of the candle. An extinguishing device is arranged above the fixing device. The beneficial effect of the present invention is that a device for lighting a candle is added to the air purifier, so that the amorphous carbon such as carbon black generated by the burning of the candle enters the kitchen air along with the purified air. While ventilating, the amorphous carbon such as carbon black scattered in the air is adsorbed, improving the smoke removal efficiency and having a better effect, and improving the air quality of the kitchen.

[0009] Chinese Patent: A High-Voltage Smoke Air Purifier (CN101954111B), comprising a housing with an air inlet and an air outlet, a double-negative high-voltage grid, a high-voltage generator, a program controller, a fan, and a power supply. The double-negative high-voltage grid includes an aluminum-magnesium-zinc alloy microporous mesh and an aluminum-magnesium-zinc alloy corrugated mesh acting as the negative electrodes, and a positive 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 stabilizing circuit for rectifying and filtering, an oscillation control circuit for generating an oscillation control signal, a humidity control circuit for generating a control signal according to air humidity, and a boosting circuit. This high-voltage smoke air purifier does not require a filter, overcoming the secondary pollution caused by the filter in air filtration in the prior art and the trouble of needing to clean the filter regularly, and generates negative oxygen ions through high-voltage discharge to purify the air. At the same time, through the corona phenomenon, it quickly eliminates smoke, harmful substances, and harmful bacteria in the air.
