Description

an air purifier

technical field

The utility model relates to an air purifier, in particular to an air purifier with a negative ion generator.

Background technique

As shown in Figure 1, the air purifier of prior art is made up of multiple air purification filter device 9, ultraviolet lamp tube 10, wind wheel 11, negative ion generator 12 and shell 20 to form purification assembly 21, when wind wheel 11 rotates, indoor dirty The air is inhaled from the air suction port 8, filtered and sterilized by multiple air purification filter devices 9 and ultraviolet rays, and the negative oxygen ions are ionized by the negative ion generator 12, and then the fresh and purified air is discharged through the air exhaust port 13, so as to realize indoor air purification. Cleaning and freshening of the air.

Negative oxygen ions have the benefits of promoting metabolism and certain health treatment effects on the human body. In addition, negative ions can charge particles such as smoke, germs, and dander in the air. The charged particles will be adsorbed on the surface of indoor objects and will not float around; but at the same time charged The particles will also be reversely adsorbed on the wind wheel and the inner wall of the purifier through the air outlet when the purifier is shut down, making it difficult to clean and easily causing secondary pollution of the air purifier to the indoor air.

Invention content:

The purpose of the utility model is to provide an air purifier which is easy to clean and can prevent secondary pollution caused by reverse suction.

The technical solution of the utility model is: an air purifier, including a purifying assembly composed of multiple air purifying and filtering devices, ultraviolet light tubes, wind wheels and negative ion generators arranged in the casing. The air outlet valve is provided on the air side, and the air outlet valve is provided with a guide pipe communicating with the air outlet of the purification component. The guide pipe extends downward to below the liquid level of the liquid contained in the lower part of the outlet valve. The top of the air outlet water valve is provided with an air outlet channel, and the air outlet channel communicates with the outside world through the air outlet.

Install a water valve device at the air exhaust port of the existing purification component. When the wind wheel rotates, the indoor dirty air is sucked in from the air suction port, and the air is filtered and sterilized by multiple air purification filter devices and ultraviolet rays, and generated by negative ions. After the negative oxygen ion is ionized by the device, the purified air through the air outlet is introduced into the liquid at the bottom of the water valve through the guide tube, generating countless bubbles, and the fresh air bubbles rise up, and are discharged into the room through the air outlet to complete the indoor air purification work; Once the purification component is shut down, the particles with negative ions cannot be reversely adsorbed in the wind wheel and the purifier due to the function of the outlet water valve, which keeps the inside of the purification component clean and prevents secondary pollution.

As an optimized solution, an air inlet water valve is provided on the air inlet side of the purification component, and a suction pipe extending to the bottom of the air inlet water valve to accommodate the liquid below the liquid level is provided at the air inlet. A suction air channel with a dry filter system communicates with the air suction port of the purification assembly. At this time, when the wind wheel rotates, the indoor dirty air is sucked into the wind water valve from the air inlet. Using the adsorption and filtration effect of the liquid on the dust, the liquid is used for filtration first to form countless bubbles. Part of the particles such as smoke and dust are precipitated and dissolved in the liquid, and the pre-filtered air rises to the surface of the liquid, and after being dried by the drying filter system along the suction air channel, it enters the purification component for further purification, disinfection and freshening treatment, and then passes through the outlet. The feng shui valve discharges to complete the indoor air purification work. At this time, the air has been pre-filtered again, so the service life of the multiple air purification filter devices can be extended several times, which can save expenses and use costs.

The purification component includes air conditioning equipment, which can be applied in different occasions.

The purification component is respectively movable connected with the air outlet water valve and the air inlet water valve, which is convenient for disassembly, cleaning and liquid replacement.

The multiple air purification and filtering devices are filter screens, activated carbon screens, oxidative decomposition technology screens, non-woven fabric screens, activated activated carbon molecular sieve screens, cold catalyst screens or photocatalyst screens, which are easy to obtain materials and are suitable for more occasions.

The utility model has the advantages that the particles with negative ions cannot be reversely adsorbed in the purification assembly due to the blocking effect of the water valve, which prevents secondary pollution; and the air is pre-filtered, so the service life of the multiple air purification filter device It can be extended several times, saving expenses and use costs, easy to use, and convenient to operate.
