The outer ends of the pair of filter screens 401 are fixedly connected to the installation frame 402, and the outer end of the installation frame 402 is provided with a slide groove 403. The outer side of the slide groove 403 is slidably connected to an operating block 404, and the end of the operating block 404 close to the slide groove 403 is fixedly connected to a moving block 405, and the outer end of the moving block 405 is fixedly connected to a slider 406, and the inside of the slide groove 403 is fixedly connected to a guide rod 407, and the slider 406 is slidably connected to the outside of the guide rod 407, and the outside of the guide rod 407 is movably connected to a spring 408, and the end of the slider 406 away from the moving block 405 is fixedly connected to a limiting column 409.

[0031] By setting up the filter assembly 4, the filter screen 401 can filter the impurities carried by the water flow in the liquid inlet pipe 203 and the liquid discharge pipe 202 to prevent the pump from being blocked. When replacing the filter screen 401, the operating block 404 is pushed toward the middle to drive the spring 408 to stretch and drive the slider 406 to slide synchronously along the guide rod 407, so that the limiting column 409 is separated from the limiting groove 204, and the filter screen 401 can be removed and cleaned and replaced.

[0032] Reference Figure 1 , Figure 3 and Figure 4 As shown, one end of the spring 408 is fixedly connected to the inner wall of the slide groove 403, and the other end of the spring 408 is fixedly connected to the slider 406.

Under the resetting action of the spring 408, the limiting column 409 can be driven to insert into the limiting groove 204, thereby completing the installation of the filter 401.

[0035] By setting the liquid receiving part 2, the diaphragm type liquid quantitative pump body 1 provides power for the diaphragm 205, so that the diaphragm 205 reciprocates up and down. When the diaphragm 205 rises, the pressure in the chamber decreases, thereby generating negative pressure and sucking in liquid. When the diaphragm descends, the pressure in the chamber increases, and the liquid is pushed out through the discharge pipe 202, thereby realizing the operation of the pump.

[0036] Reference Figure 1-Figure 3 As shown, an O-ring 208 is fixedly connected to the connection between the liquid discharge pipe 202 and the body 201 , and an O-ring 208 is fixedly connected to the connection between the liquid inlet pipe 203 and the body 201 .

[0045] Specific implementation process: The motor 101 cooperates with the pump head 102 to provide energy to the diaphragm 205, so that the diaphragm 205 reciprocates up and down. When the diaphragm 205 rises, the pressure in the chamber decreases, thereby generating negative pressure and sucking in liquid. When the diaphragm descends, the pressure in the chamber increases, and the liquid is pushed out through the discharge pipe 202, thereby realizing the work of the pump;

[0046] At the same time, the filter 401 can filter the impurities carried by the water flow in the liquid inlet pipe 203 and the liquid outlet pipe 202 to prevent the pump from being blocked;

[0047] When replacing the filter 401, the operating block 404 is pushed toward the middle to stretch the spring 408 and drive the slider 406 to slide synchronously along the guide rod 407, so that the limiting column 409 is separated from the limiting groove 204, and the filter 401 can be removed and cleaned and replaced.

[0048] After pushing the operating block 404 inward, install the installation frame 402 to a suitable position, align the limiting column 409 with the limiting groove 204, and then release the operating block 404. Under the reset action of the spring 408, the limiting column 409 can be driven to insert into the limiting groove 204, thereby completing the installation of the filter 401.
