During the process of the distance between the elastic filter 113 becoming smaller, there will be a squeezing process. The dust adhered to the elastic filter 113 is squeezed, thereby realizing the self-cleaning function of the elastic filter 113, so that personnel do not need to clean the elastic filter 113 regularly, which reduces the labor burden of personnel and ensures the air purification efficiency. .

The working principle of this clean air purification device:

When in use, add a main amount of photocatalyst into the liquid tank 2, then turn on the power to start the motor 91 and the ultraviolet lamp 7, and adjust the rotation speed of the motor 91 according to the air quality. Refer to Figure 7 (in the figure, a is the air intake and The moving direction of the rotating ring 102; b is the rotating direction of the rotating and mixing mechanism 13; c is the flow direction of the photocatalyst; d is the ultraviolet irradiation direction);

The rotation of the motor 91 will drive the rotating shaft 92 to rotate, causing the fan blades 93 to start rotating, and the gas inside the housing 1 will be extracted and discharged through the air outlet pipe 4. At this time, the inside of the housing 1 is in a negative pressure state, which will cause the rotating ring 102 to move along the The outer wall of the fixed rod 111 and the inner wall of the chute 115 slide inward and rotate at the same time. The distance between the fixed rod 111 and the limiting ring 101 gradually increases so that the return spring 104 is in a compressed state. When the rotating ring 102 moves and rotates, it will The telescopic rod 105 drives the connecting ring 112 to rotate, thereby causing the elastic filter 113 to change from the left state to the right state in Figure 8 , so that the air is filtered by the elastic filter 113 and then enters the interior of the housing 1 through the air inlet pipe 3 and is blown toward the arc. Shaped plate 132, due to the inward movement of connecting ring 112, will cause the pull rope 121 to loosen, causing the piston 122 to move upward under the repulsive force of the liquid inlet pipe 123. At this time, the photocatalyst in the liquid tank 2 will enter the inlet. In the liquid pipe 123, the liquid spray pipe 124 sprays into the housing 1;

And because the filtered air blows to the arc plate 132, the arc plate 132 will rotate, mixing the sprayed photocatalyst and air, so that the mixed air enters the space where the ultraviolet lamp 7 and the mirror 8 are located, Due to the mutual cooperation between the ultraviolet lamp 7 and the mirror 8, the space where the ultraviolet lamp 7 and the mirror 8 are located will be filled with ultraviolet rays, so that the ultraviolet rays can more fully act in the air mixed with the photocatalyst to destroy formaldehyde and oxygen in the air. Decompose, so that formaldehyde is decomposed into dicarbon gas and water, and oxygen is decomposed into oxygen ions, further reducing dust and disinfecting the air;

When the air containing dust generated by oxygen ions is discharged through the air outlet pipe 4, it will be filtered by the filter plate 94, and while filtering, due to the setting of the cleaning rod 95, the dust generated by the filter plate 94 will be filtered Cleaning is carried out so that dust enters the bottom of the air outlet pipe 4 from the square groove. When the air is discharged from the air outlet pipe 4, it will pass through the activated carbon plate 5 to further adsorb toxic gases in the air;

When the air purification is completed, turn off the motor 91 and the ultraviolet lamp 7. At this time, the swivel 102 will move outward under the action of the compressed return spring 104 and the chute 115, and then rotate through the telescopic rod 105. The connecting ring 112 rotates, causing the elastic filter 113 to change from the right state in Figure 8 to the left state in Figure 8. At this time, the aperture of the elastic filter 113 gradually becomes smaller, and mutual extrusion will occur, and the elastic filter 113 will The adhered dust is squeezed and cleaned, and during the rotation and movement of the connecting ring 112, the pull rope 121 will be pulled to cause the piston 122 to move downward, sealing the top of the liquid inlet pipe 123. When using it again, repeat the above Just operate. When the bottom of the air outlet pipe 4 is full of dust, the collected dust can be cleaned by opening the sealing plate 6 .

It should be noted that the specific models and specifications of the motor 91 and the ultraviolet lamp 7 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so the details will not be described in detail.

The above descriptions are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
