[0031] refer to Figures 1 to 4 An air purifier sewage treatment system according to an embodiment of the present invention is described.

[0032] like Figures 1 to 4 As shown, the sewage discharge system of an air purifier according to an embodiment of the present invention includes: a base 100, a C-shaped notch 110 is opened on the base 100, a sewage discharge cavity 120 is opened in the base 100, and the lower end of the sewage discharge cavity 120 is connected to a sewage discharge flow channel 130 which is arranged downwardly inclined; a sewage discharge valve seat 200, the sewage discharge valve seat 200 is installed on the base 100, and a sewage discharge channel 210 is opened in the sewage discharge valve seat 200 along the axial direction, and the sewage discharge cavity 120 is connected to the sewage discharge channel 210 through the sewage discharge flow channel 130. The electromagnetic drive mechanism 300 is arranged on the drain valve seat 200. The electromagnetic drive mechanism 300 is located in the C-shaped notch 110 of the base 100. The electromagnetic drive mechanism 300 includes a static iron core 310, a moving iron core 340 and an electromagnetic coil 350. The static iron core 310, the moving iron core 340 and the electromagnetic coil 350 are all arranged along the axis of the drain valve seat 200. The electromagnetic coil 350 is included on the outside of the static iron core 310 and the moving iron core 340. The moving iron core 340 is movably arranged on the static iron core 310 up and down. The moving iron core 340 is connected to the static iron core 310 through a spring 360. The power on and off of the electromagnetic coil 350 is controlled to control the rise and fall of the moving iron core 340. When the moving iron core 340 rises, the sewage cavity 120 is connected to the sewage channel 210; when the moving iron core 340 falls, the connection between the sewage cavity 120 and the sewage channel 210 is blocked by the moving iron core 340.

[0033] like Figures 1 to 4As shown, a C-shaped notch 110 is opened on the left side of the base 100, and a drain valve seat 200 is installed on the C-shaped notch 110. An electromagnetic drive mechanism 300 is installed on the upper end of the drain valve seat 200, and the electromagnetic drive mechanism 300 is located in the C-shaped notch 110. The electromagnetic drive mechanism 300 is used to switch the connection state between the drain channel 210 in the drain valve seat 200 and the drain cavity 120 in the base 100. Since the drain valve seat 200 and the electromagnetic drive mechanism 300 are both located in the C-shaped notch 110, the drain valve seat 200 body is cut and processed on the base 100 of the small compressed air purification device, and other components such as the valve core are attached to the base 100 of the small compressed air purification device. Therefore, the air purifier drain system is small and compact as a whole, which meets the miniaturization requirements of compressed air purification devices. The sewage channel 210 is connected to the sewage chamber 120 through the sewage flow channel 130. The sewage channel 210 can be connected and blocked with the sewage chamber 120 by controlling the power on and off of the electromagnetic coil 350, thereby completing the program-controlled automatic switching function and meeting customers' needs for miniaturization and integration of purification devices.

[0034] like Figures 1 to 4 As shown, a boss portion 220 is provided at the upper end of the drain valve seat 200, and the boss portion 220 is provided along the axis of the drain valve seat 200, and the drain channel 210 passes through the boss portion 220, and the boss portion 220 abuts against the moving iron core 340. When the electromagnetic coil 350 is energized, the moving iron core 340 is attracted and lifted upward by the electromagnetic force, and a gap is opened between the moving iron core 340 and the upper surface of the boss, and this gap connects the drain channel 210 with the drain flow channel 130 and the drain cavity 120. The high-pressure gas in the drain cavity 120 drives the sewage to flow along the drain flow channel 130 inclined downward, enters the drain channel 210 through the gap between the moving iron core 340 and the upper surface of the boss, and is discharged along the drain channel 210. When the electromagnetic coil 350 loses power, the movable iron core 340 is reset by the elastic force of the spring 360 and moves downward, and the movable iron core 340 closes the drainage channel 210 on the drainage valve seat 200, and the drainage action stops. The cone height of the boss portion 220 on the drainage valve seat 200, together with the base 100, forms a small annular liquid accumulation groove close to the drainage channel 210, which effectively improves the drainage efficiency.

[0035] like Figure 2 As shown, when the moving iron core 340 rises, the gap K between the moving iron core 340 and the boss portion 220 is smaller than the diameter D of the drain channel 210. As a result, debris cannot enter the drain channel 210, thereby effectively preventing the drain channel 210 from being blocked.

[0036] like Figures 1 to 4As shown, the electromagnetic drive mechanism 300 includes a sealing gasket 370, which is annular, coaxially arranged with the drain valve seat 200, and arranged between the drain valve seat 200 and the static iron core 310. A filter screen 140 is laid at the bottom of the drain cavity 120. It also includes a first sealing ring 230, which is arranged between the base 100 and the drain valve seat 200. The sealing gasket 370 and the first sealing ring 230 can prevent sewage leakage and improve the airtightness and reliability of the sewage system.

[0037] like Figures 1 to 4 As shown, the sewage discharge system of the air purifier also includes a heating mechanism 400, which is arranged on the base 100, and the heating mechanism 400 is located below the sewage discharge channel 130. The heating mechanism 400 is used to heat the sewage discharge channel 130 to prevent ice from blocking the sewage discharge channel 130. The heating mechanism 400 includes a heating plate 410 and a heating cover plate 420. The heating plate 410 is arranged in the base 100, and the heating cover plate 420 is covered on the base 100. The heating cover plate 420 is connected to the base 100 by bolts 430. Tightening the bolts 430 allows the heating cover plate 420 to press the heating plate 410 into the base 100. A second sealing ring 440 is arranged between the heating cover plate 420 and the base 100. When the room temperature is higher than the start-up setting value of the heating plate 410, the heating plate 410 shall not be energized, and the heating plate 410 shall not work. When the room temperature is lower than the start-up setting value of the heating plate 410, the heating plate 410 is energized and starts working. The heating power is greater than the heat dissipation power. The sewage channel 130 above the heating plate 410 is in a heated and temperature-rising state at this time, thereby effectively preventing ice from clogging the sewage channel 210.

[0038] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
