[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] A flow control device based on a water supply pipeline includes a flow control device body 1. A cleaning mechanism 2 is provided at the input end of the flow control device body 1 for filtering the water entering the flow control device body 1. The cleaning mechanism 2 includes:

[0027] The filter unit 21 is located at the input end of the flow control device body 1. It includes a cylindrical barrel 211, on which a filter cylinder 215 is fixedly installed. The filter cylinder 215 is provided with an activated carbon layer and a filter cotton layer to filter the water entering the flow control device body 1.

[0028] The backwashing unit 22 is located at the bottom of the filter unit 21 and is used to backwash the debris remaining inside the filter cartridge 215.

[0029] The disassembly and assembly unit 23 is located inside the cylindrical barrel 211 and is used to disassemble and replace the filter cartridge 215.

[0030] Water enters the interior of the filter cartridge 215 through the water supply pipe 213. The water is then filtered through the activated carbon layer and filter cotton layer inside the filter cartridge 215. The filtered water enters the interior of the flow control device body 1 through the water supply pipe 216, thereby preventing impurities inside the water from entering the interior of the flow control device body 1 and affecting its internal structure.

[0031] In this embodiment, a top cover 212 is fixedly installed on the top of the barrel 211 by bolts, a water supply pipe 216 is fixedly installed on the left end of the barrel 211, and a second valve 217 is fixedly installed on the outside of the water supply pipe 216.

[0032] The water inside the flow control device body 1 is returned when the filter cartridge 215 is replaced by opening and closing the second valve 217.

[0033] In this embodiment, a water supply pipe 213 is fixedly installed at the bottom of the cylindrical barrel 211, and one end of the water supply pipe 213 passes through the cylindrical barrel 211 and is inserted into the interior of the filter cylinder 215. A first valve 214 is fixedly installed on the outside of the water supply pipe 213.

[0034] The water supply is switched on and off by opening and closing the first valve 214.

[0035] In this embodiment, the backwashing unit 22 includes an inlet pipe 221 fixedly installed at the bottom of the cylindrical barrel 211, a third valve 222 fixedly installed on the outside of the inlet pipe 221, a drain pipe 223 fixedly installed at the bottom of the inlet pipe 221, and a fourth valve 224 fixedly installed on the outside of the drain pipe 223.

[0036] The second valve 217, the first valve 214, the third valve 222, and the fourth valve 224 are of model Q11F-16P. When cleaning the internal space of the filter cartridge 215, the second valve 217 and the first valve 214 are closed, and the third valve 222 and the fourth valve 224 are opened. At this time, water is introduced into the filter cartridge 215 through the water inlet pipe 221, and the water is discharged from the drain pipe 223, thus completing the cleaning of the inside of the filter cartridge 215.

[0037] In this embodiment, the disassembly and assembly unit 23 includes an installation ring 231 fixedly installed at the bottom of the inner cavity of the cylindrical barrel 211. A set of L-grooves 232 are opened inside the installation ring 231. The left and right sides of the filter cylinder 215 are fixedly installed with locking blocks 233, and the locking blocks 233 slide into the interior of the L-grooves 232.

[0038] The user rotates the filter cylinder 215 to make the locking block 233 slide inside the horizontal groove of the L groove 232. At this time, the filter cylinder 215 is pulled upward to make the locking block 233 slide inside the vertical groove of the L groove 232, thereby realizing the disassembly of the filter cylinder 215 and making it easy to replace the filter cylinder 215.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] During operation, water first enters the interior of the filter cartridge 215 through the water supply pipe 213, and then passes through the activated carbon layer and filter cotton layer inside the filter cartridge 215 for filtration. The filtered water then enters the interior of the flow control device body 1 through the water supply pipe 216.

[0041] Afterwards, when cleaning the internal space of the filter cartridge 215, the second valve 217 and the first valve 214 are closed, and the third valve 222 and the fourth valve 224 are opened. At this time, water is injected into the filter cartridge 215 through the water inlet pipe 221, and the water is discharged from the drain pipe 223, thus completing the cleaning of the inside of the filter cartridge 215.

[0042] Then, when replacing the filter cartridge 215, close the first valve 214, the second valve 217, the third valve 222 and the fourth valve 224, open the top cover 212, and the user rotates the filter cartridge 215 to make the locking block 233 slide inside the horizontal groove of the L groove 232. At this time, pull the filter cartridge 215 upward to make the locking block 233 slide inside the vertical groove of the L groove 232 to disassemble the filter cartridge 215.
