[0008] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of the present application. As shown in FIG. 1, an embodiment of the present application provides a cleaning gun 1. The cleaning gun 1 comprises, for example, a gun body 10, a cleaning agent storage tank 20, a tap water pipeline 31 and a spray head 32. The cleaning agent storage tank 20 is arranged on the gun body 10. The tap water pipeline 31 is arranged on the gun body 10 and away from the cleaning agent storage tank 20. The spray head 32 is connected with the output end of the tap water pipeline 31 and the output end of the cleaning agent storage tank 20 respectively. The tap water pipeline 31 has a first output end 311 and a second output end 312. The first output end 311 is connected with the input end of the cleaning agent storage tank 20. The second output end 312 is connected with the spray head 32. A piston 21 is arranged in the cleaning agent storage tank 20. The piston 21 is located in the cleaning agent storage tank 20 and abuts against the input end of the cleaning agent storage tank 20. In the embodiment, the cleaning agent storage tank 20 can be used to store cleaning agent. In other embodiments, the cleaning agent storage tank 20 can be used to store other liquids, such as foam agent and the like. Different liquids can be stored in the cleaning agent storage tank 20 according to actual scene requirements. The tap water pipeline 31 can be, for example, a pipeline in the cleaning gun for flowing tap water. The input end of the tap water pipeline 31 can be connected with a tap water faucet or other tap water pipeline. Alternatively, if the connected tap water pressure is not enough, the tap water can be connected with a booster device and the like. The piston 21 can be, for example, a rubber piston. The piston 21 is used to block tap water and cleaning agent. Since the first output end 311 of the tap water pipeline 31 is connected with the input end of the cleaning agent storage tank 20, when tap water flows into the tap water pipeline 31, the tap water will flow to the cleaning agent storage tank 20. In order to prevent tap water from mixing with cleaning agent in the cleaning agent storage tank 20, thereby causing the ratio of cleaning agent and tap water sprayed by the spray head to be incorrect and affecting the cleaning effect, the rubber piston is arranged to isolate the contact between water and cleaning agent. The rubber piston can be extruded by the water pressure of tap water, so that the cleaning agent can flow out of the output end of the cleaning agent storage tank to the spray head for spraying.The embodiment is characterized in that the cleaning agent storage tank 20 and the tap water pipeline 31 are arranged on the gun body 10 of the cleaning gun 1, the spray head 32 is connected with the output end and the second output end 312 of the cleaning agent storage tank 20, that is, the tap water and the cleaning agent are connected with the same water outlet spray head, so that the tap water and the cleaning agent are mixed together at the spray head 32 and then sprayed out through the spray head, the cleaning agent and the tap water are combined together, the piston 21 arranged in the cleaning agent storage tank 20 can isolate the tap water and the cleaning agent, the tap water is output through the first output end 311, and the water pressure of the tap water forms a thrust force to extrude the piston 21 to spray, so that the cleaning gun 1 can meet the requirements of various scenes, and the user does not need to replace the cleaning agent for many times, the replacement frequency is reduced, and the user experience and the cleaning convenience of the cleaning gun are improved. Further, the cleaning agent storage tank 20 is detachably arranged on the gun body 10. That is, the cleaning agent storage tank 20 is provided with a movable joint at both ends, the cleaning agent storage tank 20 is detached by unscrewing the movable joints at both ends when the cleaning agent needs to be added, the water in the cleaning agent storage tank 20 is drained, the cleaning agent storage tank 20 is turned over, the cleaning agent is added, and then the cleaning agent storage tank 20 is installed back to the gun body 10. The cleaning agent storage tank 20 needs to be turned over because the piston 21 has been pushed from the input end of the cleaning agent storage tank 20 to the output end of the cleaning agent storage tank 20, so the user does not need to operate to push the piston 21 back, but directly turns over the cleaning agent storage tank 20, that is, turns the input end of the cleaning agent storage tank 20 into the output end of the cleaning agent storage tank 20, and turns the output end of the cleaning agent storage tank 20 back into the input end of the cleaning agent storage tank 20. Further, the cleaning gun 1 further comprises a first valve 41 and a second valve 42, the first valve 41 is arranged at the first output end 311, and the second valve 42 is arranged at the second output end 312. The first valve 41 is in a normally open state, and the first valve 41 is closed when the cleaning agent needs to be added. The second valve 42 is used for controlling the water of the tap water pipeline 31 to flow to the spray head 32, the second valve 42 is closed when only the cleaning agent needs to be sprayed without tap water, and the second valve 42 is controlled to be opened to a suitable position when the tap water and the cleaning agent need to be mixed. Further, the cleaning gun 1 further comprises a drain port 33 and a third valve 43, the drain port 33 is arranged between the first valve 41 and the first output end 311, and the third valve 43 is arranged close to the drain port 33. The drain port 33 is used for draining the water at the first output end 311 when the cleaning gun 1 adds or replaces the cleaning agent, and the third valve 43 is opened. Further, the side, away from the tap water pipeline 31, of the cleaning agent storage tank 20 is further provided with a cover port 22, and the cover port 22 is in communication with the cleaning agent storage tank 20. The cover port 22 can be, for example, a sealing cover of the cleaning agent storage tank 20, which is used for draining the tap water flowing into the cleaning agent storage tank 20 and adding the cleaning agent, or an independent drain port and an independent feeding port.Further, the cleaning gun 1 further comprises a fourth valve 44 arranged at the output end of the cleaning agent storage tank 20. When the spray head 32 needs to spray tap water, the fourth valve 44 arranged at the output end of the cleaning agent storage tank 20 is closed and then opened, the second valve 42 is closed when spraying cleaning agent and then opened, and the fourth valve 44 is opened when the mixed water and cleaning agent needs to be sprayed out, and the fourth valve 44 and the second valve 42 are opened to a suitable proportion. Further, since the cleaning agent storage tank 20 is not detachably arranged on the gun body 10 at this time, but is fixed on the gun body, cleaning agent needs to be added into the cleaning agent storage tank 20 at this time. The specific process is as follows: first, the first valve 41 and the fifth valve 45 are closed, and then the second valve 42, the fourth valve 44 and the third valve 43 are opened, the piston 21 is pushed back to the starting point by tap water backflushing, and when the drain 33 no longer drains water, the fourth valve 44 is closed, the water in the cleaning agent storage tank 20 is emptied through the cover opening 22, and then cleaning agent is added through the cover opening 22. Further, the cleaning gun 1 further comprises a first detachable joint 34, one end of the first detachable joint 34 is connected with the input end of the tap water pipeline 31, and the other end of the first detachable joint 34 is connected with an external tap water pipe. Further, the cleaning gun 1 further comprises a gun handle 36 and a hand-held handle 37, the gun handle 36 is arranged at a suitable position at the bottom of the cleaning gun for convenient hand holding, and the hand-held handle 37 is arranged at a position at the top of the cleaning gun for convenient hand holding. The gun handle 36 can be used for operating the spray head 32 to spray out, for example, and the hand-held handle 37 can be used for conveniently carrying the cleaning gun 1, improving the convenience. Further, the cleaning gun 1 further comprises a fifth valve 45, for example, the fifth valve 45 is arranged close to the spray head 32, and the fifth valve 45 is in a normally open state. When the cleaning agent storage tank 20 needs to add cleaning agent, the fifth valve 45 needs to be closed, so that the tap water output from the second output end 312 pushes the piston in the cleaning agent storage tank 20 back to the input end of the cleaning agent storage tank 20 through the fourth valve 44, thereby facilitating the addition of cleaning agent. The specific use process of the cleaning gun 1 is as follows: when cleaning agent needs to be added during use, the fifth valve 45 and the first valve 41 are closed, the second valve 42, the third valve 43 and the fourth valve 44 are all opened, and when the drain 33 no longer drains water, the fourth valve 44 is closed and the cleaning agent storage tank 20 is emptied through the cover opening, and then cleaning agent is added. The fifth valve 45 and the first valve 41 are normally open, and the third valve 43 is normally closed during use of the cleaning gun 1. When only tap water is needed, the fourth valve 44 is closed and the second valve 42 is opened. When only cleaning agent is needed, the second valve 42 is closed and the fourth valve 44 is opened. When cleaning agent and tap water are needed, the second valve 42 and the fourth valve 44 are both opened according to a certain proportion.
