[0040] Referring to Figure 1 As shown in the drawings, an embodiment of the present application, a spray gun 1000, comprising a main body 100, a water outlet end cover 130 and a pressing piece 140, the main body 100 comprising a holding part 110 and a water outlet part 120, the side walls of the holding part 110 and the water outlet part 120 are connected, the water outlet end cover 130 and the pressing piece 140 are respectively arranged at both ends of the water outlet part 120, and a plurality of water spray holes 131 are arranged on the water outlet end cover 130. In use, the user can hold the holding part 110, then press the pressing piece 140, and water can be sprayed from the water spray holes 131 of the water outlet end cover 130, which is convenient for the user to flush the toilet, bathroom, basin, etc. or to serve as a bidet.

[0041] In order to realize that the spray gun 1000 can continuously output water after pressing the pressing piece 140 once, and reduce the manufacturing difficulty and assembly difficulty of the spray gun 1000. Referring to Figure 2 In the embodiment of the present application, the spray gun 1000 further comprises a water passing body 200, a plug 300, an actuating piece 400 and a first reset piece 500. Referring to Figure 3 As shown, the holding part 110 is provided with a water inlet channel 111, the water outlet part 120 is provided with a water outlet channel 121, and the water outlet channel 121 and the water inlet channel 111 are communicated. One end of the water outlet part 120 is further provided with a water outlet 122 communicating with the water outlet channel 121. Therefore, when the spray gun 1000 outputs water, the water passes through the water inlet channel 111 and the water outlet channel 121 in turn, and is finally discharged through the water outlet 122.

[0042] Referring to Figure 3 and Figure 5 As shown, the water passing body 200 is sealingly installed at one end of the water outlet channel 121 close to the water outlet 122, the water passing body 200 is formed with a water passing channel 210, the inner wall of the water passing channel 210 is provided with a avoiding groove 211 and a blocking part 212, the avoiding groove 211 and the blocking part 212 are arranged along the circumference of the water passing body 200, and one end of the water passing body 200 away from the water outlet 122 is provided with a water passing opening 220, the water passing opening 220 and the water passing channel 210 are communicated.

[0043] Referring to Figure 3 and Figure 7 As shown, the plug 300 comprises a sealing part 310 and a positioning part 320 connected with each other, and the sealing part 310 is used for sealingly cooperating with the water passing opening 220. The pressing piece 140 and the actuating piece 400 are hinged, and the actuating piece 400 drives the plug 300 to move along the first direction by pressing the pressing piece 140. The actuating piece 400 comprises a driving part 410, the driving part 410 is used for driving the plug 300 to rotate along the circumference of the water passing body 200. The first reset piece 500 is used for driving the plug 300 to move along the second direction, and the second direction is opposite to the first direction. For example, the first reset piece 500 can be a spring and is sleeved on the actuating piece 400, and the two ends of the spring are respectively abutted with the plug 300 and the water outlet part 120. Of course, the first reset piece 500 can also be a silica gel piece, a rubber piece, a tension spring, an electromagnetic valve, a motor and the like structure, which can drive the plug 300 to move along the second direction.

[0044] Among them, the spray gun 1000 has a normally open state and a closed state. When the spray gun 1000 is in the closed state, for example Figure 3 and Figure 8 As shown, the positioning part 320 cooperates with the blocking part 212, the plug 300 can block the water passing opening 220 under the elastic force of the first reset piece 500, at this time the water cannot enter the water passing channel 210 through the water passing opening 220, and the spray gun 1000 does not output water. When the spray gun 1000 is in the normally open state, for example Figure 4and Figure 9 The state shown Figure 4 The dashed arrows in the diagram indicate the direction of water flow. Pressing the pressing member 140 causes the actuator 400 to move the plug 300 against the elastic force of the first reset member 500, moving it along the first direction. After the plug 300 moves to the appropriate position, the driving unit 410 drives the plug 300 to rotate, causing the positioning unit 320 to rotate to a position that mates with the clearance groove 211. The sealing unit 310 opens the water inlet 220, and the water outlet channel 121 connects to the water outlet 122 through the water inlet channel 210. That is, when water enters through the water inlet channel 111, the water sequentially passes through the water outlet channel 121, the water inlet 220, and the water inlet channel 210, finally exiting from the water outlet 122.

[0045] Using the above solution, the spray gun 1000 can continuously output water without the user needing to continuously press the button 140, resulting in a better user experience. By designing the water passage 200 and the water outlet 120 as two separate components, with the water passage 200 located at the end of the water outlet 120 near the outlet 122, the structure of the water passage 200 can be simplified, the manufacturing difficulty of the water passage can be reduced, and assembly efficiency can be improved. When a part of the main body 100 or the water passage 200 is defective, the defective part can be discarded or recycled for remanufacturing, without the need for complete scrapping, thereby reducing production costs.

[0046] It should be noted that, in addition to using the pressing component 140 to move the actuator 400, it can also be moved using buttons, handles, etc. For example, in the case of a button, the button can be located at the water outlet 122 and connected to the actuator 400. To dispense water from the spray gun 1000, the button is pressed once; to turn off the water, the button is pressed again. When using a handle, the handle can be located at the end of the actuator 400 away from the water outlet 122, and pulling the handle moves the actuator 400. The appropriate solution should be selected based on the actual situation. For ease of explanation, all subsequent embodiments will be described using the pressing component 140.

[0047] To further reduce the assembly difficulty of the 200-meter water body, refer to Figure 2 and Figure 3 As shown in the embodiment of the present invention, the water-passing body 200 is installed in the water outlet channel 121 through the water outlet 122. The water outlet end cap 130 is connected to the water outlet 120. While covering the water outlet 122, the water outlet end cap 130 can abut against the water-passing body 200, thereby preventing the water-passing body 200 from leaving the water outlet channel 121. With this solution, the assembly difficulty of the water-passing body 200 is low and the assembly efficiency is high.

[0048] Reference Figure 2As shown, in the embodiment of the present application, the actuating member 400, the water passing body 200, the plug 300, the first reset member 500 and the like can be assembled outside the main body 100 first, and then installed inside the water passing body. For example, the plug 300 is first arranged in the water passing body 200, then the actuating member 400 is arranged in the plug 300 and the water passing body 200, then the first reset member 500 is sleeved, and then the whole is installed in the water outlet 120, and finally the water outlet cover 130 and the pressing member 140 are installed respectively. Therefore, the assembly difficulty of the spray gun 1000 can be greatly reduced, and the assembly efficiency is improved.

[0049] With reference to the foregoing Figure 2 As shown, in the embodiment of the present application, the water outlet cover 130 and the water outlet 120 are detachably connected, and the detachable connection can be threaded connection, buckle connection, fastener connection and the like. It can be understood that after the spray gun 1000 is used for a long time, the internal channel of the spray gun 1000 is easily blocked by various impurities such as moss, silt and the like, and some components may be damaged, such as aging of the sealing ring. The water outlet cover 130 is designed to be detachable, so that the actuating member 400, the water passing body 200, the plug 300, the first reset member 500 and the like can be easily disassembled, and the impurities can be easily cleaned, and the damaged parts can be easily replaced.

[0050] With reference to the foregoing Figure 8 and Figure 9 As shown, in the embodiment of the present application, the water passing body 200 is provided with a limiting piece 230 at one end thereof, the side wall of the plugging part 310 is provided with an annular groove 330, and the first sealing ring 340 is arranged in the annular groove 330. When the spray gun 1000 is in the closed state, the plugging part 310 is sealingly connected with the water passing port 220 through the first sealing ring 340, and when the spray gun 1000 is in the normally open state, the first sealing ring 340 and the limiting piece 230 abut. It should be noted that when the spray gun 1000 is in the normally open state, the plug 300 needs to open the water passing port 220, and under the repeated impact of the water flow, the first sealing ring 340 is easily detached. Therefore, by arranging the limiting piece 230 at one end of the water passing body 200, and adopting the abutting scheme of the first sealing ring 340 and the limiting piece 230, the probability of detachment of the first sealing ring 340 is reduced, and the reliability of the spray gun 1000 is improved.

[0051] With reference to the foregoing Figure 5 As shown, in the embodiment of the present application, the limiting piece 230 is provided with a plurality of limiting pieces 230, and the plurality of limiting pieces 230 are arranged at intervals around the circumference of the water passing body 200. Therefore, when the spray gun 1000 is in the normally open state, the first sealing ring 340 can abut against the plurality of limiting pieces 230, further improving the stability of the connection between the first sealing ring 340 and the plugging part 310, and greatly reducing the detachment of the first sealing ring 340.

[0052] With reference to the foregoingFigure 6 As shown, in the embodiment of the present application, the inner wall of the limiting sheet 230 is inclinedly arranged towards the radial outside of the water passing body 200 in the direction away from the water passing port 220. When the spray gun 1000 is switched from the closed state to the normally open state, since the limiting sheet 230 is outwardly inclinedly arranged, when the plug 300 opens the water passing port 220, the water passing area gradually increases instead of suddenly increasing. In the process of closing the water passing port 220 by the plug 300, the water passing area gradually decreases. Therefore, the impact caused by the water flow in the moment when the water passing port 220 is opened or closed can be reduced, the opening and closing of the spray gun 1000 is facilitated, and the user experience is improved.

[0053] Referring to Figure 5 As shown, in the embodiment of the present application, the inner wall of the water passing body 200 is provided with a plurality of first limiting platforms 240, the plurality of first limiting platforms 240 are arranged at intervals along the circumference of the water passing body 200, and a gap between adjacent two first limiting platforms 240 forms an avoiding groove 211. The first limiting platform 240 comprises a first protruding part 241, a second protruding part 243 and a third protruding part 245, and the second protruding part 243 is connected between the first protruding part 241 and the third protruding part 245. The first protruding part 241, the second protruding part 243 and the third protruding part 245 are respectively provided with a first inclined surface 242, a second inclined surface 244 and a third inclined surface 246 at one end thereof towards the water passing port 220, the inclination directions of the first inclined surface 242, the second inclined surface 244 and the third inclined surface 246 are the same, the first inclined surface 242 and the second inclined surface 244 are connected, and the second inclined surface 244 and the side wall of the second protruding part 245 form a blocking part 212.

[0054] Referring to Figure 7 As shown, the positioning part 320 comprises a second limiting platform 321, and the second limiting platform 321 can be one or more. When the second limiting platform 321 is provided with a plurality of second limiting platforms 321, the plurality of second limiting platforms 321 are arranged at intervals. The second limiting platform 321 is provided with a fourth inclined surface 322, and the fourth inclined surface 322 can be slidably matched with the first inclined surface 242 or the third inclined surface 246, so as to make the second limiting platform 321 rotate to a position matched with the avoiding groove 211 or a position abutted with the blocking part 212.

[0055] By adopting the above scheme, when water needs to be closed, the user presses the pressing piece 140 once, the actuating piece 400 drives the plug 300 to move to a corresponding position along the first direction, for example, a position where the second limiting platform 321 and the blocking part 212 are separated, and then the driving part 410 drives the plug 300 to rotate. After the user releases the pressing piece 140, the first restoring piece 500 drives the plug 300 to move to a position matched with the avoiding groove 211 along the second direction, for example Figure 8 As shown, the position, the avoiding groove 211 plays a role of avoiding and limiting the rotation of the plug 300, the plugging part 310 seals the water passing port 220, and the spray gun 1000 is closed.

[0056] After pressing the pressing piece 140 once again, the actuating piece 400 drives the plug 300 to move to the corresponding position in the first direction, for example, the position where the second limiting table 321 is away from the avoiding groove 211, the driving part 410 drives the plug 300 to rotate, and after the hand is released, the first restoring piece 500 drives the plug to move to the position where the plug cooperates with the blocking part 212 in the second direction, for example, the position shown in the figure. The user does not need to keep pressing the pressing piece 140, and the spray gun 1000 can be kept open. Therefore, the structure of the spray gun 1000 is reasonable, the stability of the spray gun 1000 in the open or closed state can be improved, the operation is simple, and the use is convenient. Figure 9

[0057] Referring to Figure 10 and Figure 11 In the embodiment of the present application, the fifth inclined surface 411 is arranged on the side of the driving part 410 facing the second limiting table 321. When the actuating piece 400 moves in the first direction, the second inclined surface 244 and the fourth inclined surface 322 are in sliding cooperation, so that the second limiting table 321 rotates. Therefore, the driving part 410 can drive the second limiting table 321 to rotate once every time the pressing piece 140 is pressed once, so that the second limiting table 321 cooperates with the limiting groove or the blocking part 212 in turn, the spray gun 1000 is quickly switched between the open state and the closed state, the operation is convenient, and the user has a good experience.

[0058] Referring to Figure 5 and Figure 10 In the embodiment of the present application, the outer peripheral wall of the driving part 410 is provided with a guide part 412, and the inner wall of the water passage 210 is provided with a guide groove 250, for example, the guide groove 250 can be the gap between the first convex part 241 and the third convex part 245, or the side wall at other positions of the water passage 210. The guide part 412 and the guide groove 250 are in guiding cooperation, which guides the direction of the actuating piece 400, effectively avoids the misalignment and deflection of the actuating piece 400, and improves the reliability of the spray gun 1000.

[0059] Referring to Figure 2 and 3 In the embodiment of the present application, the inside of the water outlet part 120 is provided with a guide column 123, the guide column 123 is provided with a through hole, the end of the actuating piece 400 away from the water outlet 122 penetrates the through hole, and the pressing piece 140 and the end of the actuating piece 400 penetrating the through hole are hinged. Further, the through hole can communicate with the external space of the water passage 121, the actuating piece 400 further comprises a transmission rod 420, one end of the transmission rod 420 close to the water outlet 122 is connected with the driving part 410, the transmission rod 420 penetrates the through hole, and the transmission rod 420 and the through hole are in sliding sealing through the second sealing ring, which can avoid the leakage of water, and has the advantages of simple structure, low manufacturing difficulty and high assembly efficiency.

[0060] Referring to​Figure 7 As shown, in the embodiment of the present application, the plug 300 is provided with a flow piece 350 on the side facing the water outlet 122, and the peripheral wall of the flow piece 350 is provided with flow grooves 351, for example, a plurality of flow grooves 351 are provided and are arranged at intervals along the circumference of the flow piece 350. When the spray gun 1000 needs to be watered, the plug 300 is gradually moved from the position abutting against the inner wall of the water passage 220 to the position separated from the inner wall of the water passage 220. For example, the plug 300 is gradually moved under the driving of the actuating member 400. Water mainly enters the water flow passage through the flow grooves 351 at this time, and the water passage area is small; when the plug 300 is in the position separated from the inner wall of the water passage 220, water mainly enters the water flow passage through the gap between the plugging part 310 and the water passage body 200, and the water passage area is large, that is, the water passage area changes from small to large. When the spray gun 1000 needs to be watered, the water passage area changes from large to small for the same reason.

[0061] Therefore, by providing the flow grooves 351, the water passage area of the plug 300 changes from small to large or from large to small when the plug 300 is moved, and the impact phenomenon caused by the sudden change of the water passage area is effectively improved. At the same time, after the flow grooves 351 are provided, the water flow direction changes from the direction perpendicular to the wall surface of the water passage body 200 to the oblique direction when the water enters the water passage 220, the water pressure loss is reduced, and the flow of the water is improved.

[0062] Referring to Figure 10 As shown, in the embodiment of the present application, the spray gun 1000 further comprises a second reset member 510, which is used to move the actuating member 400 in the second direction. The transmission rod 420 is provided with a limiting part 413 arranged therearound. The second reset member 510 is sleeved on the transmission rod 420, one end of the second reset member 510 abuts against the limiting part 413, and the other end abuts against one end of the guide column 123. When the pressing member 140 is pressed and then released, the second reset member 510 can drive the actuating member 400 to move in the second direction, so that the pressing member 140 can be reset after being released, and the shaking of the pressing member 140 is reduced. For example, the second reset member 510 can be a spring and is sleeved on the actuating member 400, and the two ends of the spring abut against the limiting part 413 and the guide column 123, respectively. Of course, the first reset member 500 can also be a silica gel member, a rubber member, a tension spring, an electromagnetic valve, a motor, etc., which can drive the actuating member 400 to move in the second direction.

[0063] Referring to Figure 10 and Figure 11As shown, in the embodiment of the present application, the transmission rod 420 is provided with a clamping groove 414, which is used for installing a third sealing ring. The transmission rod 420 is arranged in the plug 300 and is in sliding sealing cooperation with the plug 300 through the third sealing ring, so that the water leakage can be effectively avoided. The transmission rod 420 is arranged in the plug 300, so that when the pressing piece 140 is pressed, the actuating piece 400 can move in the first direction to drive the plug 300 to move. The structural design is reasonable and the reliability is high.

[0064] The above describes the embodiments of the present application in combination with the drawings, but the present application is not limited to the above-described embodiments, and various changes can be made within the knowledge range of the ordinary skill in the art without departing from the purpose of the present application.
