Problems solved by technology

[0002] At present, the commercially available air purification devices basically adopt the filter element dust removal mode, that is, dry adsorption dust removal. The disadvantage of this kind of air purification device is that if the filter element is not replaced in time, it will cause secondary pollution and cannot achieve the effect of air purification. At the same time, this kind of air purification device The air purification device needs to replace the filter element regularly, and the replacement of the filter element is not a small expense. Therefore, it is a technical problem to be solved at present to design a small household fresh air system with a low price and no need to replace the filter element.

Embodiment 1

[0023] Such as figure 1 , 2 Shown, a kind of multi-functional air cleaning device, comprises the ventilation pipe 2 that is arranged on the body of wall 1, the filter 3 that is arranged in the ventilation pipe and fan 4, and filter can be mesh type filter, for example described filter It is a diesel particulate filter (DPF). The filter relies on a multi-void filter element to absorb particles from the air to purify the air. The fan can be an axial fan, and the fan controls the flow of air in the ventilation pipe. The air inlet 201 of the ventilation pipe is located at Outdoors, the ventilation pipe air outlet 202 is located indoors, the ventilation pipe is connected to the first manifold 5 and the second manifold 6, and the first manifold air inlet 501 is connected to the ventilation pipe body between the fan and the ventilation pipe air outlet. The first manifold air outlet 502 communicates on the ventilation pipe between the filter and the fan, the second manifold air inlet...

Embodiment 2

[0026] Such as image 3 , 4 As shown in , 5, the difference from the first embodiment is that the filter is arranged in an independent pipe body, and the independent pipe body can be detachably plugged into the first filter socket 17 of the ventilation pipe. The pipe body of the second manifold is provided with a second filter socket 18 corresponding to the filter on the ventilation pipe, and the second control valve is located between the air inlet of the second manifold and the socket. The wall is fixedly connected to the turntable 19, and the turntable is controlled by the motor 20 to rotate, and the rotation of the turntable controls the filter to switch between the first filter socket and the second filter socket, so as to realize the communication between the filter and the pipe body , the pipe body at the rear of the second filter socket is in communication with the dust bag 21 . When the pollution of the filter on the ventilation pipe reaches a certain level, turn th...

Abstract

The invention provides a multifunctional air purification device, which relates to an air purification device. It solves the problem that the multifunctional air purification device in the prior art needs to frequently replace the filter element. The multifunctional air purification device includes a ventilation pipe, a filter and a fan arranged in the ventilation pipe, the air inlet of the ventilation pipe is located outdoors, the air outlet of the ventilation pipe is located indoors, and the ventilation pipe is connected with the first manifold and the second manifold, A first control valve is set on the first manifold, a second control valve is set on the second manifold, and a third control valve is set on the ventilation pipe between the intake port of the first manifold and the intake port of the second manifold A fourth control valve is arranged on the ventilation pipe between the first manifold air outlet and the second manifold air outlet, and a pressure detection device for detecting the difference in gas pressure on both sides of the filter is arranged on the ventilation pipe. The invention utilizes the manifold and the control valve arranged on the ventilation pipe to realize back-blowing cleaning of the purifier without changing the direction of the fan.
