If it is described to first, second, it is only used for distinguishing technical features for the purpose, and can not be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence of the indicated technical features.

[0037] In the description of the utility model, unless otherwise explicitly limited, the words such as setting, installation, connection should be broadly understood, and the specific meaning of the above words in the utility model can be reasonably determined by the person skilled in the art in combination with the specific content of the technical scheme.

[0038] In order to conveniently store and fix the spray gun when not in use, the magnetic spray gun is usually designed with a matching base, and the stable connection between the spray gun and the base is realized through magnetic attraction. Specifically, in the related art, a groove for accommodating and supporting the water outlet nozzle of the spray gun is often arranged on the base, and at the same time, a magnet is embedded in the interior of the base, so as to be attracted to the magnet arranged in the interior of the water outlet nozzle of the spray gun, so as to realize stable magnetic attraction connection.

[0039] However, based on the existing spray gun kit, the user needs to accurately find the groove position on the base through vision to align the water outlet nozzle of the spray gun with the groove for hanging and placing when hanging the spray gun, and it is difficult to directly hang the spray gun in place without observing the base. Secondly, the existing spray gun usually directly sets a magnet at the water outlet nozzle, so that during the multiple hanging and placing processes, frequent friction and collision between the water outlet nozzle and the base are caused, the risk of damage to the water outlet nozzle is increased, and the service life of the spray gun is seriously affected.

[0040] Therefore, some embodiments of the utility model put forward a spray gun assembly 1000 which can be applied to a toilet kit, a rain shower device kit and the like, and the embodiments do not limit the same, and the spray gun assembly 1000 can be specifically described with reference to Figures 1 to 10 It is shown in the description of the utility model.

[0041] Referring to Figure 1 and Figure 2 In the embodiments of the utility model, the spray gun assembly 1000 comprises a spray gun 100, a first magnetic attraction piece 200, a fixing seat 300 and a second magnetic attraction piece 400. It can be understood that the conventional spray gun often separately sets a switch assembly and a water outlet at two ends of the spray head, and such a layout makes the user only insert the end of the water outlet into the base when hanging and placing the spray gun. Based on this, in combination with Figure 5 It can be understood that in the embodiments, the spray gun 100 comprises a handle 110 and a spray head 120, wherein the handle 110 is connected to the side wall of the spray head 120, the switch assembly 111 is arranged on the handle 110, the switch assembly 111 is used for controlling the on-off of the water inlet waterway 112 in the handle 110, and the control of the switch assembly 111 by the user when holding the handle 110 is facilitated.

[0042] Specifically, referring to Figure 2 and Figure 3 , in the embodiment of the utility model, the lower end of the side wall of the spray head 120 is formed with a connector 170, and the handle 110 is detachably connected to the connector 170, which can be threaded connection, buckle connection or interference fit, and the embodiment does not limit it. It can be understood that the handle 110 is connected to the side wall of the spray head 120, which reserves a setting space for the fixed groove 131. Based on this, in the embodiment, one end of the spray head 120 is provided with a water outlet 151, and the other end is provided with a fixed groove 131, and the fixed groove 131 and the water outlet 151 are respectively arranged on the opposite sides of the spray head 120. Combined with Figure 5 and Figure 6 , in the embodiment, the first magnetic attraction piece 200 is arranged inside the spray head 120 and located between the water outlet 151 and the fixed groove 131, which reduces the influence of the fixed groove 131 and the first magnetic attraction piece 200 on the water outlet 151.

[0043] Referring to Figure 1 , in the embodiment of the utility model, the fixed seat 300 is provided with a boss 311 which is protruded from the surface of the fixed seat 300. It can be understood that when the user hangs the spray gun 100 to the fixed seat 300, the boss 311 can play the role of auxiliary positioning, which not only facilitates the user to confirm the hanging position through vision, but also enables the user to quickly judge the accurate hanging position through touch even without relying on vision. In the embodiment, the fixed seat 300 is a hollow structure, and the second magnetic attraction piece 400 is arranged inside the fixed seat 300 and located on the side of the boss 311 away from the spray head 120.

[0044] In the embodiment of the utility model, when the spray gun 100 is hung on the fixed seat 300, the boss 311 is arranged in the fixed groove 131. Specifically, the depth of the fixed groove 131 can be equal to the protrusion height of the boss 311, and the depth of the fixed groove 131 can be greater than the protrusion height of the boss 311, so as to ensure that the boss 311 can be located in the fixed groove 131. Referring to Figure 2 and Figure 4 , in one example, the depth of the fixed groove 131 is equal to the protrusion height of the boss 311, when the boss 311 is arranged in the fixed groove 131, the end surface of the spray head 120 is attached to the end surface of the fixed seat 300, which improves the connection stability of the spray gun 100 and the fixed seat 300.

[0045] Referring to Figure 1 and Figure 3As shown in the utility model embodiment, the fixed groove 131 is a circular groove, and the boss 311 is a columnar structure. Therefore, the minimum inner diameter of the fixed groove 131 is greater than the maximum outer diameter of the boss 311. In the embodiment, when the user hangs the spray gun 100, the spray gun 100 does not need to be put into the boss 311 at a specific angle, thereby further reducing the difficulty of hanging.

[0046] Referring to Figure 6 As shown in the utility model embodiment, when the boss 311 is arranged in the fixed groove 131, the first magnetic member 200 is located on one side of the bottom wall of the fixed groove 131, and the second magnetic member 400 is located on the other side of the bottom wall of the fixed groove 131. At least one of the first magnetic member 200 and the second magnetic member 400 is a magnet, and the first magnetic member 200 and the second magnetic member 400 are magnetically attracted and matched. For example, the first magnetic member 200 or the second magnetic member 400 can be a magnet, or both the first magnetic member 200 and the second magnetic member 400 are magnets.

[0047] It can be understood that the magnetic attraction and matching of the first magnetic member 200 and the second magnetic member 400 can quickly and accurately align the fixed groove 131 and the boss 311 during the hanging process of the user, thereby reducing the operation difficulty of the user in hanging the spray gun 100 and improving the accuracy and convenience of hanging. When the spray gun 100 is hung on the fixed seat 300, the magnetic attraction and matching of the first magnetic member 200 and the second magnetic member 400 can limit the boss 311 from separating from the fixed groove 131, thereby enhancing the connection stability of the spray gun 100 and the fixed seat 300 and reducing the risk of the spray gun 100 falling off.

[0048] Referring to Figure 6 As shown in the utility model embodiment, the first mounting groove 132 suitable for accommodating the first magnetic member 200 is arranged in the spray head 120. In an example, the first magnetic member 200 is columnar in shape, and the first mounting groove 132 can be a U-shaped groove, that is, the bottom wall of the first mounting groove 132 is an arc surface matched with the outer peripheral wall of the first magnetic member 200. In the direction of the fixed groove 131 towards the water outlet 151, the fixed groove 131 and the first mounting groove 132 are arranged in sequence.

[0049] Specifically, continuing to refer to Figure 6 As shown in the utility model embodiment, the first mounting groove 132 and the fixed groove 131 are provided with a partition plate 133, one side surface of the partition plate 133 is the bottom wall of the fixed groove 131, and the other side surface is the side wall of the first mounting groove 132. It can be understood that in the embodiment, the first mounting groove 132 is arranged adjacent to the fixed groove 131, which can make the first magnetic member 200 as close as possible to the boss 311 arranged in the fixed groove 131, thereby facilitating the magnetic attraction and matching process between the first magnetic member 200 and the second magnetic member 400.

[0050] With reference to Figure 7 As shown in the utility model embodiment, the spray head 120 comprises a valve core 130 and a shell 140, wherein the fixing groove 131 and the first mounting groove 132 are arranged on the valve core 130, and the fixing groove 131 and the first mounting groove 132 are arranged side by side along the length direction of the valve core 130. Specifically, in order to facilitate the assembly of the first magnetic member 200, the opening of the first mounting groove 132 is arranged upward on the surface of the valve core 130. Based on this, when assembling, the first magnetic member 200 only needs to be put into the opening of the first mounting groove 132, and the upward opening can reduce the possibility of the first magnetic member 200 being separated from the first mounting groove 132.

[0051] With reference to Figure 6 and Figure 7 As shown in the utility model embodiment, the shell 140 is provided with a containing groove 141, and the containing groove 141 penetrates through the shell 140 along the length direction of the valve core 130, based on which the valve core 130 is arranged in the containing groove 141. When assembling, the first magnetic member 200 is first put into the first mounting groove 132 from the opening of the first mounting groove 132, and then the valve core 130 is arranged in the containing groove 141 from one end of the shell 140. It can be understood that when the valve core 130 is arranged in the containing groove 141, the inner wall of the containing groove 141 covers the opening of the first mounting groove 132, thereby avoiding the possibility of the first magnetic member 200 being separated from the valve core 130.

[0052] With reference to Figure 6 As shown in the utility model embodiment, the bottom wall of the first mounting groove 132 is perpendicular to the connecting direction of the first magnetic member 200 and the second magnetic member 400 in the direction of the opening of the first mounting groove 132. In this embodiment, the opening direction of the first mounting groove 132 is upward, and the first magnetic member 200 and the second magnetic member 400 are arranged in the length direction of the valve core 130. It can be understood that the connecting direction of the first magnetic member 200 and the second magnetic member 400 is the direction of the magnetic force, and therefore, under the stable action of the magnetic force, the first magnetic member 200 can be stably kept in the first mounting groove 132, thereby further reducing the possibility of the first magnetic member 200 being separated from the first mounting groove 132.

[0053] With reference to Figure 5 and Figure 7As shown in the utility model embodiment, the spray head 120 further comprises a water outlet piece 150, and a water outlet 151 is formed in the water outlet piece 150. Specifically, in one example, the water outlet piece 150 is provided with a plurality of water outlets 151, the water outlets 151 are circular holes, and the plurality of water outlets 151 are uniformly arranged on the end face of the water outlet piece 150. In the embodiment, the water outlet piece 150 is arranged in the accommodating groove 141 and connected to the side of the valve core 130 away from the fixing groove 131. During assembly, the valve core 130 is first arranged in the accommodating groove 141 from one end of the shell 140, then the water outlet piece 150 is arranged in the accommodating groove 141 from the other end of the shell 140, and finally the water outlet piece 150 is connected to the valve core 130. It should be noted that the water outlet piece 150 and the valve core 130 can be connected by screws, buckles or other fastening connection modes, and the embodiment does not limit the connection mode.

[0054] Referring to Figure 5 and Figure 6 As shown in the utility model embodiment, the first magnetic member 200 is a magnet, and a water outlet channel 134 is formed in the valve core 130 and spaced apart from the first mounting groove 132. Specifically, the water outlet channel 134 is in communication with the water inlet channel 112 and the water outlet 151. Based on this, water flows from the water inlet channel 112, through the water outlet channel 134 and out of the water outlet 151. It can be understood that, since the first mounting groove 132 is spaced apart from the water outlet channel 134, on the one hand, the first magnetic member 200 can be prevented from releasing metal substances into the water flow, and on the other hand, after the water flow in the water outlet channel 134 passes through the magnetic field formed by the first magnetic member 200, the water molecules are arranged in order, so that the water quality is improved to a certain extent.

[0055] Referring to Figure 8 As shown in the utility model embodiment, the spray head 120 further comprises a water collecting piece 160, and the water collecting piece 160 is arranged at the water outlet 151. In one example, the water outlet piece 150 is provided with a plurality of water outlets 151, and correspondingly, the water collecting piece 160 is also provided with a plurality of water collecting pieces 160, and the plurality of water collecting pieces 160 are arranged one by one in the water outlets 151. For example, the water collecting piece 160 is made of soft rubber. In the embodiment, the water collecting piece 160 is provided with a water collecting hole 161 in communication with the water outlet channel 134, and the cross-sectional area of the water collecting hole 161 gradually decreases along the water flow direction.

[0056] Specifically, continuing to refer to Figure 8 As shown in the utility model embodiment, the water collecting hole 161 has a water inlet end and a water outlet end, and in the embodiment, the cross-sectional area of the water outlet end is smaller than that of the water inlet end. During the process of water flow from the water inlet end to the water outlet end, the flow rate can be significantly improved due to the gradual decrease of the cross-sectional area, which not only helps the water flow to be more smooth and efficient from the water outlet channel 134, but also enhances the scouring ability of the water flow.

[0057] With reference to Figure 9 As shown in the utility model embodiment, the fixing seat 300 is of a split structure, specifically, the fixing seat 300 comprises a shell 310 and a cover plate 320, the shell 310 has a boss 311 protruding from one side, and a second mounting groove 312 is formed on the other side. In the embodiment, one side surface of the end of the boss 311 is the end surface of the boss 311, and the other side surface is the bottom wall of the second mounting groove 312. The second magnetic attraction member 400 is arranged in the second mounting groove 312, so that when the boss 311 is arranged in the fixing groove 131, the second magnetic attraction member 400 can be as close as possible to the first magnetic attraction member 200, thereby achieving a more compact and efficient magnetic attraction effect.

[0058] With reference to Figure 9 As shown in the utility model embodiment, the cover plate 320 is arranged on the side of the shell 310 opposite to the boss 311, and the shell 310 and the cover plate 320 are detachably connected, thereby facilitating the disassembly and assembly of the second magnetic attraction member 400. Specifically, the shell 310 and the cover plate 320 can be connected by screws, can be connected by interference fit, or can be connected by other detachable connection modes, and the embodiment does not limit the connection mode.

[0059] With reference to Figure 10 As shown in the utility model embodiment, the second magnetic attraction member 400 is of a columnar structure, and a plurality of limiting ribs 313 are arranged at intervals on the inner circumferential wall of the second mounting groove 312. The limiting ribs 313 protrude from the inner circumferential wall of the second mounting groove 312, and the plurality of limiting ribs 313 respectively abut against the outer circumferential wall of the second magnetic attraction member 400, thereby cooperating to limit the second magnetic attraction member 400 from being separated from the second mounting groove 312. Specifically, as shown in Figure 6 and Figure 10 As shown, the plurality of limiting ribs 313 can form a limiting groove 314 therearound, and the inner diameter of the limiting groove 314 is smaller than the outer diameter of the second magnetic attraction member 400. Therefore, when the second magnetic attraction member 400 is arranged in the limiting groove 314, the plurality of limiting ribs 313 can form an interference fit with the second magnetic attraction member 400, thereby stably fixing the second magnetic attraction member 400 in the second mounting groove 312.
