[0002] Some existing intelligent toilets are generally equipped with a spray gun, which is generally inserted into a fixed bracket for convenient cleaning of the toilet, and the water flow entering from the water inlet channel is split into the intelligent toilet and the spray gun. However, intelligent toilets have relatively high requirements for water quality, so filter sheets are generally provided in the water inlet channel. However, the existing filter sheets are generally installed in the water inlet channel or at the joint, making it difficult to replace. Generally, the entire valve head or the fixed bracket needs to be disassembled during replacement, which brings great inconvenience to users and results in a poor experience. In addition, the spray gun is also prone to damage under the long-term action of high pressure. Summary of the Utility Model

[0021] Combined with Figures 1 to 3 As shown, this embodiment provides a spray gun assembly, including a spray gun 1, a connecting pipe 2, and an angle valve 3 that facilitates the replacement of the filter element. The connecting pipe 2 is adapted to be connected to the angle valve 3, and the spray gun 1 is adapted to be inserted into the angle valve 3. The angle valve 3 that facilitates the replacement of the filter element includes a valve head 31, on which a water inlet passage 32 and a first water outlet 33 and a second water outlet 34 communicated with the water inlet passage 32 are formed. The first water outlet 33 extends outward to connect to a bracket 38 for placing the spray gun 1; it also includes a filter element device 35, and the filter element device 35 is detachably inserted into the water inlet passage 32 to filter the water flow entering the first water outlet 33 and the second water outlet 34; a first switch assembly 26 is provided at the upstream end of the water inlet passage 32 where the filter element device 35 is located, so as to cut off the water flow entering the filter element device 35 first when replacing the filter element device 35.

[0022] In this embodiment, the upstream end refers to the upstream of the water outlet direction of the water inlet passage 32. When the water path at the upstream end is cut off, the water flow entering the filter element device 35 and the first water outlet 33 and the second water outlet 34 is also cut off, and thus it is convenient to replace the filter element device 35 or disassemble the hoses connected to the first water outlet and the second water outlet, etc. In this solution, the filter element device 35 is independent of the water outlet, and the filter element device can be replaced without disassembling the hose. The first switch assembly 36 is integrated on the valve head, which is convenient for the user to operate.

[0023] Continue to combine with Figures 1 to 3As shown, in this embodiment, the valve head 31 is adapted to be installed on the wall surface, the water inlet channel 32 is perpendicular to the wall surface, that is, the outer end of the water inlet channel 32 faces the user, and the filter element device 35 is adapted to be inserted into the water inlet channel 32 facing the outer end, so as to facilitate the user to replace the filter element device 35. In this embodiment, the filter element device 35 includes an operation part and a filter element tube. The filter element tube is adapted to be inserted into the water inlet channel 32, and the side wall of the filter element tube is closely attached to the first water outlet 33 and the second water outlet 34, so that the water flow in the water inlet channel 32 can enter the first water outlet 33 and the second water outlet 34 only after passing through the filter element tube; the operation part is exposed outside the valve head 31 for the convenience of the user to operate. Here, the filter element device 35 can be a filter screen rolled into a cylindrical shape, or an existing filter element product can be adopted. After the water flow entering from the water inlet channel 32 enters the filter element device 35, it then enters the first water outlet 33 and the second water outlet 34, so that the water flowing out from the first water outlet 33 and the second water outlet 34 can be effectively filtered. The filter element device 35 and the valve head 31 are connected by threads for easy disassembly and assembly. The operation part is provided with external threads, and the water inlet channel 32 is provided with external threads, so that the filter element device 35 can be directly installed and disassembled by means of thread connection. And because the installation port at the outer end of the water inlet channel 32 faces the user, it is convenient for the user to replace. In other embodiments, the operation part can also be provided with a reserved "one" - shaped groove to facilitate the user to operate with a coin.

[0024] A first switch assembly 36 is provided at the upstream end of the water inlet channel 32 between the first water outlet 33 and the second water outlet 34. The first switch assembly 36 includes a switch handle and a ball valve provided in the water inlet channel 32. The switch handle is provided on the upper side of the valve head 31 for the convenience of the user to operate. When the user needs to replace the filter element device 35, the ball valve can be closed first to cut off the water flow in the water inlet channel 32, and then the filter element device 35 can be replaced, which is convenient to operate.

[0025] In this embodiment, the first water outlet 33 can be used to communicate with the spray gun 1, and the second water outlet 34 can be connected to the intelligent toilet or other water outlet devices. Among them, the first water outlet 33 is vertically downwardly provided on the valve head 31, and a bracket 38 is provided outside the first water outlet 33 for inserting the spray gun 1. The first water outlet 33 and the second water outlet 34 are distributed on the side of the water inlet channel 32.

[0026] Combined with Figures 1 to 3As shown, a second switch assembly 37 is provided at the first water outlet 33. The bracket 38 is rotatably connected to the second switch assembly 37, and when the bracket 38 rotates, it is adapted to drive the second switch assembly 37 to open or close. The second switch assembly 37 includes a valve core. The bracket 38 is adapted to connect to the valve stem of the valve core to drive the on / off of the valve core when rotating. In other embodiments, the bracket 38 is adapted to connect to the valve stem of the valve core through a connecting rod (not shown) to drive the on / off of the valve core when rotating. That is to say, the bracket 38 is rotatably connected to the valve core, and the second switch assembly 37 is used to close when the spray gun 1 is not in use to prevent the interior of the spray gun 1 from being under high pressure for a long time. In this embodiment, when the bracket 38 rotates to the front end, the valve core opens, and when the bracket 38 rotates to the side of the valve head 31, the valve core closes. When the bracket 38 rotates towards the user, the second switch assembly 37 is in the open state; this is because, usually when the spray gun 1 is not in use, the user is used to placing it on one side to reduce space occupancy. Therefore, this design can remind the user to close the second switch assembly 37 in time when the spray gun 1 is not needed to avoid the spray gun 1 being under high pressure for a long time. It should be noted that when the bracket 38 rotates to one side of the water inlet channel 32 (i.e., the side away from the front side facing the user), it is on the opposite side of the second water outlet 34 to prevent interference with each other. In this embodiment, the first switch assembly 36 can be kept in the normally open state, and the second switch assembly 37 is opened when using the spray gun 1. In other embodiments, the rotation direction of the bracket 38 can be front-back, up-down or left-right, and all can achieve the reminder effect.

[0027] Through the solution of this embodiment, on the one hand, it is convenient to replace the filter element, and on the other hand, it can also prevent the spray gun 1 from being under high pressure for a long time.

[0028] It should be understood that: the above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention.
