[0032] Referring to Figures 1 to 8 , a spray gun, comprising: a housing 100;

[0033] A switching device is built into the housing 100. The switching device includes an inlet pipe 150, a rotary switching valve 140, and an outlet pipe assembly that are connected in sequence. The rotary switching valve 140 is movably arranged in the inlet pipe 150. The rotary switching valve 140 is suitable for controlling the flow direction of the liquid in the inlet pipe 150. The outlet pipe assembly is provided with a first flow channel and a second flow channel. A water sealing member 180 is provided at the abutment between the inlet pipe 150 and the outlet pipe assembly. The water sealing member 180 is sequentially provided with a first opening 200 and a second opening 220. The first opening 200 is provided corresponding to the first flow channel, and the second opening 220 is provided corresponding to the second flow channel.

[0034] When the rotary switching valve 140 connects the first opening 200 , a water flow channel is established between the first flow channel and the water inlet pipe 150 ; when the rotary switching valve 140 connects the second opening 220 , a water flow channel is established between the first flow channel and the water inlet pipe 150 .

[0035] By controlling the switching of water flow between different flow channels through the rotary switching valve 140, a variety of water flow modes are provided to the user, ensuring a quick response when switching flow channels, enriching the user's experience, and meeting the user's personalized bathing needs; the water inlet pipe 150, the rotary switching valve 140 and the water outlet pipe assembly are integrated in the housing 100 to form a compact and efficient internal structure, improve the aesthetics of the product, and thus improve the user's experience; the user only needs to rotate the rotary switching valve 140 to control the switching of the water flow, without the need for complicated operations, and with a low learning cost.

[0036] A sealing portion 210 is provided between the first opening 200 and the second opening 220. The cross-sectional area of ​​the sealing portion 210 is larger than the water outlet of the rotary switching valve 140. When the sealing portion 210 covers the water outlet of the rotary switching valve 140, a closed space is formed in the water inlet pipe 150. When the rotary switching valve 140 rotates to the sealing portion 210, the sealing portion 210 can completely cover the water outlet of the rotary switching valve 140, thereby preventing water from leaking when the flow channel is not selected, thereby improving the watertightness of the spray gun and reducing the waste of water resources.

[0037] Reference Figures 3 to 6 The outer wall of the rotary switching valve 140 is provided with a boss 170. The boss 170 provides a clear point of force, and the user can more easily apply external force to the rotary switching valve 140, thereby improving the smoothness of water flow switching. The boss 170 is integrally formed with the rotary switching valve 140. The production steps are simplified and the reliability of the connection between the boss 170 and the rotary switching valve 140 is improved.

[0038] Reference Figure 7, the switching device further includes a face cover 160 disposed within the housing 100. The face cover 160 is provided with a push handle 110 and is in driving connection with the convex post 170. When the push handle 110 is pushed, the rotary switching valve 140 switches between the first opening 200 and the second opening 220. The design of integrating the push handle 110 on the face cover 160 can ensure direct and stable transmission when the push handle 110 is operated. It not only rationally utilizes the internal space of the housing 100 to make the overall structure more compact, but also gives the product a better aesthetic appearance.

[0039] The face cover 160 is provided with a guide groove 190 which is spiral. The convex post 170 is movably installed within the guide groove 190. The spiral guide groove 190 can ensure that the convex post 170 moves smoothly along a predetermined trajectory during rotation, facilitating the user to finely control the water flow pattern. The guide groove 190 can also provide an increasing damping feeling, enabling the user to better control the water flow pattern. It can be understood that by providing a spiral groove on the face cover 160, the linear pushing action of the push handle 110 can be converted into the rotational motion required by the rotary switching valve 140, magnifying a small linear displacement into a large rotational motion, and further improving the user's interaction experience with the spray gun.

[0040] The face cover 160 can switch the rotational motion of the rotary switching valve 140 into a linear pushing motion, making it more convenient for the user to switch. Moreover, it can magnify the stroke of the push handle 110, convert the linear motion into a spiral motion, and magnify the small stroke of the push handle 110 into a large rotation of the face cover 160. The face cover 160 and the water sealing member 180 are arranged opposite to each other. It can make better use of the internal space of the spray gun, making the entire device structure more compact.

[0041] Referring to Figures 1 to 3 , the water outlet pipe assembly includes a first water outlet pipe 130 and a second water outlet pipe 120 which are connected in series and conductively connected. The first water outlet pipe 130 is adapted to conductively connect the water inlet pipe 150 and the second water outlet pipe 120, and the second water outlet pipe 120 is adapted to conductively connect the first water outlet pipe 130 and the water using device. The first water outlet pipe 130 is disposed on the side wall of the water inlet pipe 150, and the second water outlet pipe 120 and the water inlet pipe 150 are arranged on the same axis. Optimizing the layout of the internal pipeline reduces the tortuosity of the water flow path, reduces the loss of water pressure, shortens the overall length of the spray gun, and makes the overall design of the spray gun more compact. It can be understood that the water using device can be a spray gun head which is provided with a flowing water mode and a spraying mode. Different water outlet effects can be achieved by providing different water outlet nozzles on the spray gun head. The nozzles for the flowing water mode and the spraying mode are respectively connected to the first flow channel and the second flow channel. When the user uses it, by adjusting the rotary switching valve 140, the water outlet mode of the spray gun head can be controlled, thereby realizing the switching of multiple water outlet modes.

[0042] It can be understood that the water flow transmission path starts from the connection between the water inlet pipe 150 and an external water source, then reaches the rotary switching valve 140, is guided by the first water outlet pipe 130, flows to the second water outlet pipe 120, and finally reaches the water-using device.

[0043] The inner side wall of the housing 100 is provided with positioning ribs, and the side walls of the second water outlet pipe 120 and the water inlet pipe 150 are provided with clamping portions 230, and the clamping portions 230 are clamped to the positioning ribs. It can achieve quick and accurate installation positioning and improve the installation efficiency.

[0044] The outer wall of the rotary switching valve 140 is provided with a concave portion 240, and the shape of the concave portion 240 is mutually adapted to that of the water sealing member 180, and the water sealing member 180 is clamped to the concave portion 240. It can evenly distribute the acting force, avoid local stress concentration, enhance the stability of the water sealing member 180 during use, reduce displacement or damage caused by vibration or external impact, and extend the service life of the product.

[0045] Refer to Figures 1 to 8 In this embodiment, a spray gun structure is provided. The housing 100 of the spray gun is made of ABS plastic, which has good water resistance and corrosion resistance. A switching device is arranged inside the housing 100, and the switching device is composed of a water inlet pipe 150, a rotary switching valve 140 and a water outlet pipe assembly. The rotary switching valve 140 is fitted and installed inside the water inlet pipe 150. When the user rotates the rotary switching valve 140, the direction of the water flow in the water inlet pipe 150 can be controlled.

[0046] The water sealing member 180 is designed to be made of silicone rubber, which not only ensures a good sealing effect but also maintains good elasticity in a high-temperature environment. The first opening 200 and the second opening 220 provided thereon are precisely matched with the rotary switching valve 140 to ensure the sealing performance during water flow switching. A sealing portion 210 made of silicone rubber is arranged between the first opening 200 and the second opening 220. The size of the sealing portion 210 is larger than that of the rotary switching valve 140 to ensure that when the rotary switching valve 140 is closed, it can completely cover the water outlet to form a sealed space and effectively prevent water leakage. The water sealing member 180 is provided with a first opening 200, a sealing portion 210 and a second opening 220. The first opening 200 of the water sealing member 180 corresponds to the first flow channel and the second flow channel respectively. When the water outlet of the rotary switching valve 140 is aligned with the first opening 200, the first flow channel is water-conductively connected to the water inlet pipe 150. When the water outlet of the rotary switching valve 140 is aligned with the second opening 220, the second flow channel is water-conductively connected to the water inlet pipe 150. The user controls the direction of the water flow by changing the relative position between the rotary switching valve 140 and the water sealing member 180.

[0047] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the relevant art.
