Problems solved by technology

However, in the above scheme, the wettability of water is poor, and it cannot effectively wet the adhesion and take away various pollutants on the surface of the filter, which makes the self-purification effect and efficiency of the device poor.
At the same time, after a period of use, the water in the water tank will become cloudy and need to be replaced frequently
Secondly, the water mist produced by the shower device will increase the humidity of the filtered air, which will easily cause discomfort to the user.

Embodiment 1

[0029] like Figures 1 to 9 As shown, a self-cleaning filter type air cleaner based on a high-performance wetting agent includes a housing 1, and a filter screen 8, a peristaltic pump 7, a spraying device, a control panel 5, and a fan 12 arranged in the housing 1, Wherein: the housing 1 is a hollow structure with an open upper end and a closed lower end, an air inlet 9 is provided on the side wall of the housing 1 , and an air outlet 10 is provided on the top of the housing 1 . The inlet of the peristaltic pump 7 is connected with the water inlet pipe 6, and the washing liquid is passed into the water inlet pipe 6, and the washing liquid contains a wetting agent, and the outlet of the peristaltic pump 7 is connected with the spraying device through the conduit 4, and the spraying device is located inside the filter screen 8 ; The control panel 5 is arranged on the outer wall of the shell 1, and the control panel 5 is electrically connected with the peristaltic pump 7 . An ann...

Embodiment 2

[0040] The structure of the air purifier of this embodiment is the same as that of Embodiment 1, except that the filter element 15 of this embodiment is melt-blown cloth and nylon.

Embodiment 3

[0042] The structure of the air purifier of this embodiment is the same as that of Embodiment 1, except that the filter element 15 of this embodiment is cotton, silk, melt-blown cloth and nylon.

[0043] Embodiments 1 to 3 have adopted different filter elements, what the filter element of embodiment 1 adopted is cotton and silk, what the filter element of embodiment 2 adopted is melt-blown cloth and nylon, what the filter element of embodiment 3 adopted is cotton, silk, melt Spray cloth, nylon. The three filter elements have good filtering effects on hydrophobic and hydrophilic dust, and different filter elements can be used for different dust environments. In the above embodiments, the self-purification ability of the air purifier is greatly enhanced, the service life of the filter screen is greatly improved, and the purification effect is obviously improved.

Abstract

The invention discloses a self-cleaning filter type air purifier based on a high-performance wetting agent, and the air purifier comprises a shell, and a filter screen, a peristaltic pump, a sprayingdevice, a control panel and a fan which are arranged in the shell; the shell is of a hollow structure with an open upper end and a closed lower end, an air inlet is formed in the side wall of the shell, and an air outlet is formed in the top of the shell; an inlet of the peristaltic pump is connected with a water inlet pipe, washing liquid is introduced into the water inlet pipe, the washing liquid contains a wetting agent, an outlet of the peristaltic pump is connected with a spraying device through a guide pipe, and the spraying device is located above the interior of the filter screen; thecontrol panel is arranged on the outer wall of the shell and electrically connected with the peristaltic pump. Due to the fact that the wetting effect of the efficient wetting agent is far better thanthat of water, compared with a common water filtering type air purifier, the self-cleaning and filtering effects are higher, and the service life of a filter screen is longer.

Description

technical field [0001] The invention belongs to the technical field of air purification equipment, in particular to a self-cleaning filter air cleaner based on a high-performance wetting agent. Background technique [0002] In daily life, we not only have to face the problem of diversification of organic pollutants, but also face the health hazards of solid particulate pollutants such as PM2.5 and even bacteria and viruses. [0003] Existing air purifiers basically use composite high-efficiency filters to block and adsorb solid particle pollutants and harmful gases in the air under the action of fans. However, the deposited and adhered dust particles cannot automatically fall off from the filter screen. As time goes by, more and more dust particles are deposited on the surface of the filter screen, resulting in larger air resistance of the filter screen, slower air purification speed, and lower purification efficiency. Low, so that the life of the filter is shortened, the c...
