[0022] Embodiment

[0023] Please refer to Figure 1 - Figure 2 , the present application provides a technical solution: a releaser with a self-cleaning function, including a gland 110, a locking member 120, a cylinder body 130, a perforated column water passing plate 140, a pressure relief orifice plate 150, a compression spring seat 160, a compression spring 170, and a perforated column 190. The gland 110 is installed and fixed on the cylinder body 130 through the locking member 120. The perforated column water passing plate 140 is a hollow column type and is fixed inside the cylinder body 130. The locking member 120 includes a bolt 121 and a gasket 122. The gasket 122 is sleeved on the bolt 121. The bolt 121 threadedly penetrates through the gland 110, and the end of the bolt 121 is also threaded inside the cylinder body 130. The setting of the gasket 122 makes the bolt 121 more firmly fixed on the gland 110. The cylinder body 130 includes an upper half cylinder body 1301 and a lower half cylinder body 1302. The upper half cylinder body 1301 and the lower half cylinder body 1302 are fixed together. The gland 110 is simultaneously clamped on the upper half cylinder body 1301 and the lower half cylinder body 1302. The settings of the upper half cylinder body 1301 and the lower half cylinder body 1302 facilitate the disassembly of the releaser. Two positioning slide rods are radially symmetrically arranged inside the upper half cylinder body 1301 to cooperate with the chute of the pressure relief orifice plate 150 to ensure the axial movement of the pressure relief orifice plate 150. The gland 110 is of a convex platform hollow type;

[0024] The pressure relief orifice plate 150 is slidably arranged in the cylinder body 130. The compression spring seat 160 is also fixed in the cylinder body 130. The compression spring 170 is fixed between the pressure relief orifice plate 150 and the compression spring seat 160. One end of the perforated column 190 is fixed on the water passing plate 140 with the perforated column. The perforated column 190 penetrates through the pressure relief orifice plate 150. A through hole 193 is formed in the pressure relief orifice plate 150. An O-ring 180 is arranged on the compression spring seat 160. The arrangement of the O-ring 180 increases the sealing performance after the compression spring seat 160 and the pressure relief orifice plate 150 are fitted together. A chute 191 is formed in the compression spring seat 160. The pressure relief orifice plate 150 is slidably arranged on the chute 191. The arrangement of the chute 191 facilitates the movement of the pressure relief orifice plate 150 in the compression spring seat 160. Compression spring fixing grooves 192 are formed in the pressure relief orifice plate 150 and the compression spring seat 160. The compression spring 170 is fixed between the two compression spring fixing grooves 192. The arrangement of the compression spring fixing grooves 192 facilitates the installation of the compression spring 170. A water passing hole 194 is formed in the compression spring seat 160. Uniform water passing through holes are arranged between the perforated column 190 and the surrounding cylinder body 130. A pressure relief hole is formed in the pressure relief orifice plate 150. The arrangement of the water passing hole 194 facilitates the passage of water. A sealing ring installation groove 195 is formed in the compression spring seat 160. The O-ring 180 is installed in the sealing ring installation groove 195. The arrangement of the sealing ring installation groove 195 facilitates the installation of the O-ring 180 onto the compression spring seat 160. An ear plate 196 is fixed on the outer wall of the cylinder body 130. An ear plate 196 is also fixed on the outer wall of the gland 110. The arrangement of the ear plate 196 facilitates the installation of the gland 110 and the cylinder body 130 onto the air flotation device.

[0025] Another embodiment of the present application further provides an air flotation device, and the ear plate 196 is installed together with a connecting member on the air flotation device.

[0026] Specifically, the working principle of the releaser and the air flotation device with self-cleaning function: During use, when working normally, the high-pressure dissolved air water enters the releaser from the water inlet side, pushing the pressure relief orifice plate 150 to move axially to the right until it abuts against the O-ring 180. The high-pressure dissolved air water sprays out from the pressure relief orifice to release the pressure, forming micro-bubble dissolved air water. During normal operation, if the pressure relief orifice is blocked and the aperture becomes smaller, the pressure of the high-pressure dissolved air water will change, increase, and the flow rate will decrease. The pressure relief orifice needs to be cleaned. At this time, stop the high-pressure pump of the high-pressure dissolved air water, and the dissolved air water returns to normal pressure. The pressure relief orifice plate 150 moves axially to the left under the action of the compression spring 170. The perforated column 190 passes through the release hole, pushing the blockage in the hole to the right side of the pressure relief orifice plate 150, achieving the purpose of cleaning the release hole. The blockage flows out with the water at the outlet. After the releaser is cleaned, the releaser has a self-cleaning function, eliminating the step of disassembling and cleaning it, saving time and effort, and bringing a better user experience to the user.
