The self-cleaning component 2 performs reverse flushing of the impurities retained at the water inlet end of the spray pump body 1.

[0043] The self-cleaning component 2 includes: a double-ended connecting pipe 21, which is equipped with a first valve 211, and whose outlet end is connected to the inlet end of the spray pump body 1; a filter housing 22, whose outlet end is connected to the inlet end of the double-ended connecting pipe 21, and whose inner cavity is equipped with a filter sleeve 221, the open end of which is connected to the outlet end of the filter housing 22, and which is used to filter the water entering the double-ended connecting pipe 21; and a guide pipe 23, whose outlet end is connected to the inlet end of the filter housing 22, and which is connected to the double-ended connecting pipe 21 via a circulation component 24, which is used to reverse the flow of external water into the filter housing 22 to backwash the filter sleeve 221.

[0044] Thus, the spray pump body 1 is started, and the external water source enters the filter housing 22 through the guide pipe 23. The water source permeates through the filter sleeve 221 and enters the double-ended connecting pipe 21. The water source flows through the double-ended connecting pipe 21 and enters the spray pump body 1 for use. Some of the impurities blocked by the filter sleeve 221 are attached to the outer wall of the filter sleeve 221, and some are retained in the filter housing 22. When it is necessary to clean the filter housing 22, the first valve 211 of the double-ended connecting pipe 21 is closed. Under the action of the circulation component 24, the water source of the guide pipe 23 directly enters the double-ended connecting pipe 21, and the water source flows back into the inner cavity of the filter sleeve 221 to clean the impurities in the filter housing 22.

[0045] Specifically, the spray pump body 1 is installed in the spray pipeline. Both ends of the double-ended connecting pipe 21 are equipped with flanges.

[0046] In some embodiments, such as Figure 3 As shown, the circulation component 24 includes: a circulation pipe 241, the inlet end of which is connected to the guide pipe 23, the outlet end of which is connected to the double-ended connecting pipe 21, the outlet end of which is located at the front end of the first valve 211, and the circulation pipe 241 is equipped with a second valve 241a; and a circulation pump 242, which is located in the middle of the circulation pipe 241.

[0047] Specifically, the circulation pipe 241 connects the diversion pipe 23 and the double-ended connecting pipe 21, the second valve 241a is used to control the opening and closing of the circulation pipe 241, and the circulation water pump 242 is used for diversion.

[0048] In some embodiments, such as Figure 4 As shown, a drain component 222 is provided at the bottom of the filter housing 22, which is used to discharge impurities from the filter housing 22.

[0049] The drain component 222 includes: a drain pipe 222a, which is connected to the filter housing 22, and a sealing cap 222b is provided at the end of the drain pipe 222a away from the filter housing 22;

[0050] Specifically, the drain pipe 222a is located at the bottom of the filter housing 22 to facilitate the reverse collection of impurities into the drain pipe 222a. The sealing cap 222b is detachably connected to the drain pipe 222a. When draining, the sealing cap 222b needs to be opened.

[0051] In addition, valves can also be used to control the opening and closing of the sewage pipe 222a.

[0052] In some embodiments, such as Figure 2 As shown, a flange is installed at the end of the flow guide pipe 23 away from the filter housing 22. The flange is used to connect to an external pipe.

[0053] The flange at the end of the flow guide pipe 23 away from the filter housing 22 is adapted to the external pipe to facilitate the connection of the entire structure to the external spray pipeline.

[0054] In some embodiments, such as Figure 5 As shown, the outlet end of the spray pump body 1 is equipped with a diversion component 3, which is used to connect the spray pump body 1 to external spray pipes in different directions.

[0055] The diversion assembly 3 includes: a diversion shell 31, which is connected to the outlet end of the spray pump body 1 by bolts 311; and a transverse connecting pipe 32, one end of which is connected to the diversion shell 31, and the other end of which is equipped with a flange.

[0056] Specifically, the diversion shell 31 is machined into a cylindrical shape. The diversion shell 31 is connected to the water outlet of the spray pump body 1 by bolts 311. The transverse connecting pipe 32 is used to connect to the transverse external spray pipe. (When not in use, the transverse connecting pipe 32 needs to be sealed with a plug).

[0063] There is no specific limit to the number of sewage pipes 222a that can be used.

[0064] In some embodiments, such as Figure 1 As shown, a support frame 242a is installed at the bottom of the circulating water pump 242, and the support frame 242a is connected to the ground at a preset height.

[0065] The support frame 242a is used to support the circulating water pump 242. The design of the support frame 242a increases the stability of the circulating water pump 242 during use.

[0066] In some embodiments, such as Figure 3 As shown, the circulation pipe 241 is machined into a U-shape.

[0067] The circulation pipe 241 is U-shaped, which facilitates crossing the filter housing 22 to connect the double-ended connecting pipe 21 and the flow guide pipe 23.

[0068] The working principle of this application is illustrated below with a preferred embodiment:

[0069] External water enters the filter housing 22 through the guide pipe 23. The water permeates through the filter sleeve 221 and enters the double-ended connecting pipe 21. The water flows through the double-ended connecting pipe 21 and enters the spray pump body 1 for use. Some of the impurities blocked by the filter sleeve 221 are attached to the outer wall of the filter sleeve 221, and some are retained in the filter housing 22. When it is necessary to clean the filter housing 22, the first valve 211 of the double-ended connecting pipe 21 is closed, and the second valve 241a on the circulation pipe 241 is opened. Under the action of the circulating water pump 242, the water from the guide pipe 23 enters the double-ended connecting pipe 21 directly through the circulation pipe 241. The water flows back into the inner cavity of the filter sleeve 221 to clean the impurities in the filter housing 22. The sealing cap 222b of the drain pipe 222a is opened, and then the impurities and water are discharged through the drain pipe 222a.

[0070] With the first valve 211 open and the second valve 241a closed, the water source is introduced into the diversion shell 31 by the spray pump body 1. The water flow is divided in the diversion shell 31. Part of the water flow enters the horizontal spray pipeline through the horizontal connecting pipe 32, and the other part of the water flow enters the telescopic pipe 332 through the branch pipe 331. The water flow enters the vertical spray pipeline through the telescopic pipe 332. In addition, when the third valve 331a is closed, the water flow can only enter the horizontal connecting pipe 32.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
