[0066] Referring to Figure 3 , Figure 4 and Figure 5 As shown, in an embodiment of the present invention, the switch assembly 200 may be inserted through the mounting hole 112 and mounted on the mounting portion 123. The switch assembly 200 can connect or block the first water passage 121 and the second water passage 122. Among them, the mounting hole 112 may be provided at one end of the first outer shell 110 facing the water outlet of the water outlet head 300, so that it is convenient for the user to trigger the switch assembly 200 more comfortably when holding the handle 100, providing a better user experience for the user.

[0067] Referring to Figure 1 , Figure 2 and 3 As shown, in an embodiment of the present invention, the water outlet head 300 may include a second outer shell 310 and a water outlet assembly 320. Among them, the second outer shell 310 may include a water control portion 311 and a connecting portion 312 connected to each other. The water control portion 311 may be disposed above the connecting portion 312. The water control portion 311 may enclose to form a receiving cavity 3111, and the size of the receiving cavity 3111 is adapted to accommodate the water outlet assembly 320, so that the water outlet assembly 320 can be placed in the receiving cavity 3111. The side wall of the water control portion 311 may include at least two connectors communicating with the receiving cavity 3111. The connectors may extend outward from the side wall of the water control portion 311. In this embodiment, at least two connectors may be arranged at intervals along the circumferential direction of the water control portion 311. The connectors may be two, and the two connectors are respectively disposed on opposite sides of the water control portion 311, or may be three or four, and the three or four connectors may be evenly arranged. This embodiment does not limit this. The connecting portion 312 may extend from the lower end surface of the water control portion 311 in a direction away from the receiving cavity 3111. The connecting portion 312 may be hollow, and the interior of the connecting portion 312 may also communicate with the receiving cavity 3111. The connecting portion 312 is used to connect with the handle 100.

[0068] Referring to Figure 3 、 Figure 6 and 7 As shown, in the embodiment of the present invention, the water outlet assembly 320 may include a valve core 321 and at least two water outlet members. The valve core 321 is disposed in the accommodation cavity 3111. Specifically, the shape and size of each joint are adapted for the valve core 321 to pass through. Therefore, the valve core 321 can enter the accommodation cavity 3111 from any one of the joints and be fixed in the accommodation cavity 3111. The shape and size of the joint can also meet the assembly of the water outlet member. Therefore, at least two water outlet members can be correspondingly installed in at least two joints. The valve core 321 may be provided with at least two water outlet waterways. The number of the water outlet waterways and the number of the joints can both correspond to the number of the water outlet members, so that at least two water outlet members can be correspondingly installed in at least two joints and respectively connected to the valve core 321, so that the water outlet member is communicated with the corresponding water outlet waterway. The number of the water outlet waterways and the water outlet members may be two or three. This embodiment does not limit this. In this embodiment, each water outlet member can discharge water in different ways. For example, when there are two water outlet members, the two water outlet members can be two of the water outlet ways such as shower water outlet, bubble water outlet, fan-shaped water outlet, etc. When there are three water outlet members, the three water outlet members can be three of the water outlet ways such as shower water outlet, bubble water outlet, fan-shaped water outlet, etc. Those skilled in the art can select and set according to the actual situation. This embodiment does not limit this. The handle 100 can be connected to the connecting portion 312 and can rotate relative to the water outlet head, so that the second waterway 122 can be respectively communicated with different water outlet waterways. Specifically, the inner core 120 in the handle 100 can pass through the connecting portion 312 and be rotatably connected to the valve core 321, that is, the inner core 120 can enter the second housing 310 from the connecting portion 312, so as to be rotatably connected to the lower end of the valve core 321. The valve core 321 and the inner core 120 can rotate to communicate the second waterway 122 with one of the water outlet waterways.

[0069] Referring to Figure 4 、 Figure 6 and 7As shown, it can be understood that the water inlet ends of at least two water outlet channels can be arranged at the lower end of the valve core 321, and the water outlet end of the second water channel 122 can be arranged at the top end of the inner core 120. Based on this, when the switch assembly 200 connects the first water channel 121 and the second water channel 122, one of the water outlet channels in the valve core 321 can be connected to the second water channel 122 by rotating the water outlet head 300, and the water flow can be ejected from the water outlet member corresponding to this water outlet channel. In this embodiment, the second water channel 122 can be connected to the water outlet channel corresponding to one of the water outlet members, and by rotating the water outlet head 300, the second water channel 122 can be connected to different water outlet channels, thereby switching the water outlet of the water outlet member. Since each water outlet member has a different water outlet mode, the nozzle can thus eject water in different water outlet modes.

[0070] In the embodiment of the present invention, by providing a handle 100 formed by combining an inner core 120 and a first outer shell 110, a first water channel 121 and a second water channel 122 are arranged in the inner core 120, and the first water channel 121 and the second water channel 122 are connected or blocked by a switch assembly 200 to control the on / off of water of the spray gun 1000. Also, by providing a water outlet head 300 formed by combining a water outlet assembly 320 and a second outer shell 310, the valve core 321 is placed in an accommodation cavity 3111 formed by surrounding a water control part 311, and at least two connectors are provided on the water control part 311. At least two water outlet members capable of ejecting water in different ways are respectively installed at each connector, and at least two water outlet members are correspondingly connected to at least two water outlet channels in the valve core 321 one by one. The valve core 321 can be rotatably connected to the inner core 120 to connect the second water channel 122 to one of the water outlet channels, and by rotating to switch the water outlet mode of the nozzle, modular setting of the spray gun 1000 is achieved. This not only reduces the production difficulty of components, but also enables the inner core 120, the first outer shell 110, the switch assembly 200, the water outlet assembly 320 and the second outer shell 310 to be respectively processed and formed and then assembled, greatly reducing the assembly difficulty of the spray gun 1000, shortening the assembly time required, reducing the production cost, and improving the production efficiency of the spray gun 1000.

[0071] Refer to Figure 3 、 Figure 8 and Figure 9As shown, in an embodiment of the present invention, the valve core 321 may include a water inlet portion 3211 and a water outlet portion 3212. The shape and size of the joint are adapted to the passage of the water outlet portion 3212. Therefore, the water outlet portion 3212 can pass through any one of the joints to enter the accommodation cavity 3111, and the water outlet portion 3212 can be fixed in the accommodation cavity 3111. The bottom end of the connecting portion 312 may be provided with a connection port 3121 communicating with the accommodation cavity 3111. The shape and size of the connection port 3121 are adapted to the passage of the water inlet portion 3211. The water inlet portion 3211 can pass through the connection port 3121 to enter the accommodation cavity 3111 and be connected to the water outlet portion 3212. It can be understood that when the water outlet portion 3212 and the water inlet portion 3211 are connected, a water outlet waterway can be formed inside, wherein the water inlet end of the water outlet waterway can be arranged at the water inlet portion 3211, and the water outlet waterway can be arranged at the water outlet portion 3212.

[0072] Referring to Figure 3 , Figure 8 and Figure 9 As shown, in an embodiment of the present invention, a through groove 32111 extending circumferentially along the water inlet portion 3211 is provided on the peripheral wall of the end of the water inlet portion 3211 away from the water outlet portion 3212, that is, the through groove 32111 can be arranged on the peripheral wall of the lower end of the water inlet portion 3211. The through groove 32111 can be a circular ring or a semi-circular ring, and the through groove 32111 can penetrate the outer wall of the water inlet portion 3211. A fixing groove 124 corresponding to the through groove 32111 may be provided on the peripheral wall of one end of the inner core 120 facing the valve core 321, and the fixing groove 124 can be recessed inward. It should be noted that the lower end opening of the water inlet portion 3211 is adapted to the passage of the inner core, so the water inlet portion 3211 can be sleeved on the inner core 120 to communicate the through groove 32111 with the fixing groove 124, that is, the positions of the through groove 32111 and the fixing groove 124 overlap. The water outlet assembly 320 further includes a fixing clip 330. The fixing clip 330 passes through the through groove 32111 and is sleeved in the fixing groove 124 to be slidably connected to the inner core 120. It can be understood that the fixing clip 330 can be an elastic fixture with an inward clamping force. The two ends of the fixing clip 330 can respectively pass through the through groove 32111 and abut against the fixing groove 124, thereby realizing the stable connection between the valve core 321 and the inner core 120. Based on this, the fixing clip 330 and the groove wall of the fixing groove 124 can move relatively, that is, the fixing clip 330 can slide along the fixing groove 124. Therefore, the fixing clip 330 not only plays a role in axially fixing the connection between the water inlet portion 3211 and the inner core 120, but also realizes the rotational connection between the two. In this embodiment, the rotational connection between the water inlet portion 3211 and the inner core 120 is realized through the fixing clip 330, which can reduce the difficulty of connecting the water inlet portion 3211 and the inner core 120 and improve the efficiency of assembling the valve core 321 and the inner core 120.

[0073] Referring to Figure 3 and Figure 6As shown, in the embodiment of the present invention, at least two positioning portions 125 may be provided on the upper end surface of the inner core 120. The at least two positioning portions 125 are arranged at intervals along the circumferential direction of the inner core 120. The water outlet assembly 320 further includes a positioning member 340. The positioning member 340 may be elastically connected to the lower end surface of the water inlet portion 3211. Specifically, a second spring 390 may be provided between the positioning member 340 and the lower end surface of the water inlet portion 3211, so that the positioning member 340 can approach or move away from the inner core 120 along the axial direction of the water inlet portion 3211. It can be understood that the number of the positioning portions 125 may correspond to the number of the water outlet members. When the second waterway 122 is communicated with a certain water outlet waterway, the positioning member 340 can be connected to one of the positioning portions 125. In this embodiment, the position of the positioning portion 125 corresponds to the position where the positioning member 340 is located when the second waterway 122 is communicated with a certain water outlet waterway. The arrangement of the positioning member 340 and the positioning portion 125 can enable the water outlet head 300 to remain stable after switching the water outlet member for water outlet, reduce the possibility that the water outlet head 300 rotates by itself due to water pressure, and improve the direction accuracy of the water outlet of the water outlet head 300. Refer to Figure 3 and Figure 6 As shown, in one embodiment, the end of the positioning member 340 facing the inner core 120 may be a protrusion.

The upper cross-section of the inner core 120 may be provided with a second seal 130, and the second seal 130 may be sleeved at the outlet of the second waterway 122. When the water inlet part 3211 is sleeved on the inner core 120, the second seal 130 may abut against the lower end face of the water inlet part 3211. The sizes of the second seal 130 respectively match the first water inlet hole 32113, the second water inlet hole 32114, and the third water inlet hole 32115. Specifically, when the second waterway 122 is communicated with the first water outlet waterway 3213, the second seal 130 may abut against the lower end face of the water inlet part 3211 and surround the first water inlet hole 32113, so as to ensure that the water flow in the second waterway 122 can all flow into the first water outlet waterway 3213, improving the tightness when the valve core 321 is connected to the inner core 120.

[0079] Referring to Figure 3 and Figure 6As shown, in the embodiment of the present invention, the first water outlet member 322 may include a mounting groove 3222. Specifically, the edge of the water outlet member may extend toward the valve core 321 to form a side wall, which not only allows the side wall to abut against the inner wall of the accommodating cavity 3111 to enhance the stability of the water outlet member, but also limits the formation of the mounting groove 3222. The water outlet assembly 320 also includes a connecting member 350 disposed between the water outlet portion 3212 and the first water outlet member 322. One end of the connecting member 350 is connected to the first water outlet member 322, and the other end is connected to the valve core 321. It can be understood that the size of the water outlet end of the first water outlet waterway 3213 is smaller than that of the first water outlet member 322. Therefore, in order to expand the water flow outward, the present embodiment may set a connecting member 350 between the valve core 321 and the first water outlet member 322.

[0080] Reference Figure 3 and Figure 6 As shown, in the embodiment of the present invention, the connecting member 350 may include a clamping portion 351 and a water passing portion 352, a third waterway 3521 is formed inside the water passing portion 352, a water inlet end of the third waterway 3521 may be connected to a water outlet end of the first water outlet waterway 3213, and a water outlet end of the third waterway 3521 may be connected to the mounting groove 3222 and then to the first water outlet hole 3221. The cross-sectional area of ​​the inner wall of the water passing portion 352 forming the third waterway 3521 may be gradually expanded along the water flow direction, so that the water flow in the valve core 321 can flow more smoothly to the first water outlet member 322. The end of the water outlet portion 3212 facing the first joint 3112 is provided with a first positioning groove 32121, and the first positioning groove 32121 extends in the direction of the fourth joint 3115. The inner diameter of the first positioning groove 32121 matches the outer diameter of one end of the water passing portion 352, so that one end of the water passing portion 352 can be inserted into the first positioning groove 32121. The provision of the first positioning groove 32121 can reduce the difficulty of assembling the connecting member 350, so that it can be more conveniently and quickly connected and fixed to the valve core 321. The other end of the water passing portion 352 is inserted into the installation groove 3222, that is, the end of the water passing portion 352 away from the valve core 321 can be inserted into the installation groove 3222, so that the third waterway 3521 connects the installation groove 3222 with the first water outlet waterway 3213.

[0081] Reference Figure 3 , Figure 6 and Figure 11 As shown, the outer wall of the water inlet portion 3211 may be provided with a connecting groove 32112, and the connecting groove 32112 may be recessed toward the center direction of the water inlet portion 3211. The clamping portion 351 is sleeved on the connecting groove 32112. Specifically, the two ends of the clamping portion 351 may respectively abut against the two ends of the connecting groove 32112. It should be noted that the clamping portion 351 may be an elastic clamp with an inward clamping force.

[0082] It can be understood that since the third water passage 3521 of the connecting member 350 is respectively communicated with the first water outlet passage 3213 of the valve core 321 and the first water outlet hole 3221 in the first water outlet member 322, in order to ensure a stable water outlet water pressure of the water outlet head 300, referring to Figure 3 and Figure 6 As shown, in the embodiment of the present invention, a first water sealing member 3224 may be provided between the water passing portion 352 and the inner wall of the first positioning groove 32121. The first water sealing member 3224 is sleeved on the outer peripheral wall of the water passing portion 352 and abuts against the inner wall of the first positioning groove 32121.

The water outlet assembly 320 further includes a connecting column 370. The connecting column 370 may pass through the second connection hole 3226 and be fixedly connected to the first connection hole 3216, thereby fixing the first water outlet member 322 to the water outlet portion 3212 and improving the stability of the first water outlet member 322. It can be understood that the second connection hole 3226 may be arranged in the first water outlet member 322, and the water flowing out of the first water outlet member 322 is likely to flow into the second connection hole 3226. Based on this, in this embodiment, the second connection hole 3226 may be provided with a first sealing member 380. The outer diameter of the first sealing member 380 matches the inner diameter of the second connection hole 3226, that is, the first sealing member 380 can cover the second connection hole 3226, thereby blocking the water flow from entering the second connection hole 3226. Specifically, the inner walls of the first connection hole 3216 and the second connection hole 3226 may be provided with internal threads, and the connecting column 370 may be a screw.

[0084] Referring to Figure 3As shown, in the embodiment of the present invention, a plurality of positioning ribs 3223 are circumferentially arranged at intervals on the outer peripheral wall of the first water outlet member 322. The number of positioning ribs 3223 can be three or four, and the present embodiment does not limit this. A plurality of limiting grooves 31121 are provided on the inner wall of the first joint 3112. The extending direction of the limiting grooves 31121 can be the direction in which the first water outlet member 322 moves into the first joint 3112 and towards the valve core 321 during assembly, so that the first water outlet member 322 can move along the limiting grooves 31121 during assembly, and further enable the plurality of positioning ribs 3223 to pass through the plurality of limiting grooves 31121 one by one. The connection between the limiting grooves 31121 and the positioning ribs 3223 not only plays a guiding role during the assembly of the first water outlet member 322, reducing the assembly difficulty of the first water outlet member 322, but also improves the stability of the first water outlet member 322 after assembly.

[0085] Referring to Figure 3 , Figure 7 and Figure 10 As shown, in the embodiment of the present invention, a second positioning groove 32122 is provided at one end of the water outlet portion 3212 facing the second water outlet member 323. The second positioning groove 32122 can extend towards the third joint 3114. The inner diameter of the second positioning groove 32122 matches the outer diameter of the second water outlet member 323, enabling the second water outlet member 323 to be installed in the second positioning groove 32122. Specifically, an internal thread can be provided on the inner wall of the second positioning groove 32122, and an external thread corresponding to the internal thread can be provided on the outer peripheral wall of the second water outlet member 323. The second water outlet member 323 is threadedly connected to the water outlet portion 3212. It can be understood that threaded connection has the advantages of simplicity, easy operation, and good loosening prevention effect. Based on this, the setting of the second positioning groove 32122 can reduce the assembly difficulty of the second water outlet member 323, enabling it to be more conveniently and quickly connected and fixed to the valve core 321, and at the same time improving the stability of the second water outlet member 323.

The third positioning groove 32123 can extend in the direction of the second joint 3113. The inner diameter of the third positioning groove 32123 matches the outer diameter of the third water outlet member 324, so that the third water outlet member 324 can be installed in the third positioning groove 32123. Specifically, the groove wall of the third positioning groove 32123 can be provided with a bayonet 32124, and the outer peripheral wall of the third water outlet member 324 can be provided with a buckle 3242, and the buckle 3242 is clamped with the bayonet 32124. It can be understood that the clamping connection has the advantages of easy operation and firm connection. Based on this, the setting of the third positioning groove 32123 can reduce the difficulty of assembling the third water outlet member 324, enabling it to be more conveniently and quickly connected and fixed to the valve core 321, and at the same time improving the stability of the third water outlet member 324.

[0087] Referring to Figure 3 As shown, in the embodiment of the present invention, the water inlet part 3211 passes through the first opening 32131, the second opening 32141, and the third opening 32151 respectively through the first convex part 32132, the second convex part 32142, and the third convex part 32152, thereby realizing the connection with the water outlet part 3212 and forming the first water outlet channel 3213, the second water outlet channel 3214, and the third water outlet channel 3215. Therefore, during assembly, first place the water outlet part 3212 into the receiving cavity 3111 from the second joint 3113 or the third joint 3114, and then make the water inlet part 3211 pass through the connecting part 312 and connect with the water outlet part 3212. The connecting member 350 can pass through the first joint 3112 and be connected to the valve core 321 through the clamping part 351. The first water outlet member 322 can be sleeved on the connecting member 350 through the installation groove 3222, thereby realizing the connection with the valve core 321. At the same time, the first water outlet member 322 can be connected and fixed to the second housing 310 through the connection between the positioning rib 3223 and the limiting groove 31121, and then the connection and fixation of the valve core 321 are realized. The second water outlet member 323 and the third water outlet member 324 can be respectively passed through the second joint 3113 and the third joint 3114 and connected to the valve core 321. Referring to Figure 3 、 Figure 4 and Figure 5As shown, in the embodiment of the present invention, the installation part 123 includes a water control hole 1231 extending radially along the inner core 120. Both ends of the water control hole 1231 are respectively communicated with the first water path 121 and the second water path 122. The water flow in the first water path 121 can flow to the second water path 122 through the water control hole 1231. The switch assembly 200 includes a valve rod 210, a third water sealing member 220 and a pressing member 230. The pressing member 230 is arranged at the installation hole 112 for the user to press, thereby triggering the switch assembly 200.

Specifically, the third water sealing member 220 can be arranged at one end of the valve rod 210 away from the pressing member 230.

[0088] Wherein, the valve rod 210 has a first position and a second position. The pressing member 230 drives the valve rod 210 to move along the water control hole 1231 so as to move from the first position to the second position. When the valve rod 210 is in the first position, the third water sealing member 220 abuts against the inner wall of the water control hole 1231 to block the first water path 121 and the second water path 122, so that no water flow passes through the second water path 122 and the valve core 321, and no water is ejected from the first water outlet member 322, the second water outlet member 323 and the third water outlet member 324. When the user presses the pressing member 230, the valve rod 210 can be moved from the first position to the second position. When the valve rod 210 is in the second position, the third water sealing member 220 stops abutting against the inner wall of the water control hole 1231, and a gap is formed therebetween, so that the first water path 121 and the second water path 122 are communicated. The water flow passes from the first water path 121 through the gap between the third water sealing member 220 and the inner wall of the water control hole 1231 and flows to the second water path 122. The water flow passes through the valve core 321 and is ejected from one of the first water outlet member 322, the second water outlet member 323 and the third water outlet member 324. It can be understood that the inner wall of the water control hole 1231 can extend obliquely. Specifically, the cross-sectional area of the water control hole 1231 can gradually increase along the moving direction of the valve rod 210 when the pressing member 230 is pressed.

Correspondingly, two guiding columns 231 may be provided. The two guiding columns 231 are respectively inserted into the guiding holes 1232 in a one-to-one correspondence. When the pressing part 230 is pressed, it can move along the direction of the guiding hole 1232, thereby ensuring the accuracy of the moving direction of the pressing part 230 and improving the user's pressing experience.

[0090] Refer to Figure 3 、 Figure 4 and Figure 13 As shown, in the embodiment of the present invention, a convex platform 113 may be provided on the inner wall of the first outer shell 110. The convex platform 113 may be provided at the bottom end of the inner cavity 111 of the first outer shell 110, and the convex platform 113 may extend inward. Correspondingly, a first clamping part 126 that is clamped with the convex platform 113 may be provided on the outer peripheral wall of the inner core 120.
