One end of the water outlet portion 120 is further provided with a water outlet 122 communicating with the water outlet channel 121. Therefore, when the spray gun 1000 discharges water, the water sequentially passes through the water inlet channel 111 and the water outlet channel 121 and finally is discharged through the water outlet 122.

Referring to fig. 3 and 5, the water passing body 200 is hermetically installed at one end of the water outlet channel 121 near 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 an avoidance groove 211 and a blocking part 212, the avoidance groove 211 and the blocking part 212 are circumferentially arranged along the water passing body 200, one end of the water passing body 200 far away from the water outlet 122 is provided with a water passing port 220, and the water passing port 220 is communicated with the water passing channel 210.

Referring to fig. 3 and 7, the plug 300 includes a blocking portion 310 and a positioning portion 320 connected to each other, and the blocking portion 310 is adapted to be in sealing engagement with the water outlet 220. The pressing member 140 is hinged to the actuating member 400, and the actuating member 400 drives the plug 300 to move along the first direction by pressing the pressing member 140. The actuator 400 includes a driving portion 410, and the driving portion 410 is configured to drive the plug 300 to rotate along the circumferential direction of the water body 200. The first reset device 500 is configured to move the plug 300 in a second direction, which is opposite to the first direction. For example, the first reset element 500 may be a spring and is sleeved on the actuating element 400, and two ends of the spring respectively abut against the plug 300 and the water outlet 120. Of course, the first reset element 500 may also be a silicone element, a rubber element, a tension spring, an electromagnetic valve, a motor, and the like, and may be capable of driving the plug 300 to move along the second direction.

Wherein the spray gun 1000 has a normally open state and a closed state. When the spray gun 1000 is in a closed state, for example, the state shown in fig. 3 and 8, the positioning portion 320 and the blocking portion 212 cooperate, the plug 300 can block the water passing port 220 under the elastic force of the first reset member 500, and at this time, water cannot enter the water passing channel 210 through the water passing port 220, and the spray gun 1000 cannot discharge water. When the lance 1000 is in a normally open state, such as the states shown in fig. 4 and 9, the dashed arrows in fig. 4 indicate the direction of water flow. Pressing the pressing member 140, so that the actuating member 400 drives the plug 300 to overcome the elastic force of the first reset member 500 and move along the first direction; after the plug 300 moves to a proper position, the driving part 410 drives the plug 300 to rotate, so that the positioning part 320 rotates to a position matched with the avoidance groove 211, the plugging part 310 opens the water passing port 220, and the water outlet channel 121 is communicated with the water outlet 122 through the water passing channel 210. That is, when the water inlet channel 111 is filled with water, the water sequentially passes through the water outlet channel 121, the water outlet 220 and the water outlet channel 210, and finally the water is discharged from the water outlet 122.

By adopting the scheme, the spray gun 1000 can be ensured to continuously discharge water without continuously pressing the pressing piece 140 by a user, and the user experience is good. Through designing the water passing body 200 and the water outlet 120 into two parts, and the water passing body 200 is arranged at one end of the water outlet 120 close to the water outlet 122, the structure of the water passing body 200 can be simplified, the manufacturing difficulty of the water passing body is reduced, and the assembly efficiency is improved. When one part in the main body 100 or the water passing body 200 is unqualified, the unqualified part is discarded or re-melted, and the whole discarding is not needed, so that the production cost is reduced.

It should be noted that, in addition to the manner of the pressing member 140 being used to drive the actuator 400 to move, the manner of a button, a handle, etc. may be used to drive the actuator 400 to move. For example, a button scheme is adopted, the button can be arranged at the water outlet 122 and connected with the actuating piece 400, and when the spray gun 1000 is required to discharge water, the button is pressed once; when the water is turned off, the button is pressed once more. When a pull handle is used, the pull handle may be disposed at an end of the actuating member 400 facing away from the water outlet 122, and the actuating member 400 is moved by pulling the pull handle. In particular, a suitable scheme is selected according to practical situations, and for convenience of explanation, all the following embodiments will be described in a manner of using the pressing member 140.

In order to further reduce the difficulty in assembling the water passing body 200, referring to fig. 2 and 3, 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 cover 130 is connected to the water outlet portion 120, and the water outlet end cover 130 covers the water outlet 122 and can be in abutting fit with the water passing body 200, so as to limit the water passing body 200 from being separated from the water outlet channel 121. By adopting the scheme, the assembly difficulty of the water passing body 200 is low, and the assembly efficiency is high.

Referring to fig. 2, in the embodiment of the present invention, the actuating member 400, the water body 200, the plug 300, the first restoring member 500, etc. may be assembled outside the main body 100 and then installed inside the water body. For example, the plug 300 is first disposed in the water passing body 200, then the actuating member 400 is inserted through the plug 300 and the water passing body 200, then the first reset member 500 is sleeved, then the whole is mounted in the water outlet 120, and finally the water outlet end cover 130 and the pressing member 140 are respectively mounted. Therefore, the assembling difficulty of the spray gun 1000 can be greatly reduced, and the assembling efficiency can be improved.

With continued reference to FIG. 2, in embodiments of the present invention, the outlet end cap 130 and the outlet 120 are removably coupled, which may be by a threaded connection, a snap fit connection, a fastener connection, or the like.

When the spray gun 1000 is in the normally open state, the plug 300 needs to open the water passing port 220, and the first sealing ring 340 is easily separated under repeated impact of water flow. Therefore, by providing the limiting piece 230 at one end of the water body 200 and adopting the scheme of abutting the first sealing ring 340 and the limiting piece 230, the probability of falling off of the first sealing ring 340 is reduced, and the reliability of the spray gun 1000 is improved.

Referring to fig. 5, in the embodiment of the present invention, a plurality of limiting plates 230 are provided, and the plurality of limiting plates 230 are disposed at intervals around the circumference of the water body 200. Therefore, when the spray gun 1000 is in the normally open state, the first sealing ring 340 can be abutted against the plurality of limiting pieces 230, so that the stability of connection between the first sealing ring 340 and the plugging portion 310 is further improved, and the falling-off condition of the first sealing ring 340 is greatly reduced.

Referring to fig. 6, in the embodiment of the present invention, the inner wall of the limiting piece 230 is inclined toward the radial outside of the water passing body 200 in a direction away from the water passing port 220. When the spray gun 1000 is switched from the closed state to the normally open state, the water passage area is gradually increased, not suddenly increased, when the stopper 300 opens the water passing port 220 due to the outwardly inclined arrangement of the stopper 230. The water passage area of the plug 300 is gradually reduced in the process of closing the water passing port 220. Therefore, the impact caused by the instant of opening or closing the water flow port 220 can be reduced, the spray gun 1000 can be conveniently opened or closed, and the use experience of a user is improved.

The first stopper 240 includes a first protrusion 241, a second protrusion 243, and a third protrusion 245, and the second protrusion 243 is connected between the first protrusion 241 and the third protrusion 245. The first protrusion 241, the second protrusion 243 and the third protrusion 245 are provided with a first inclined surface 242, a second inclined surface 244 and a third inclined surface 246 at one end facing the water passing port 220, the inclined 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 third protrusion 245 face the side wall of the second protrusion to form the blocking part 212.

Referring to fig. 7, the positioning portion 320 includes one or more second limiting tables 321, and when a plurality of second limiting tables 321 are provided, a plurality of second limiting tables 321 are provided at intervals. The second limiting platform 321 is provided with a fourth inclined plane 322, and the fourth inclined plane 322 can be in sliding fit with the first inclined plane 242 or the third inclined plane 246, so that the second limiting platform 321 rotates to a position matched with the avoidance groove 211 or a position matched with the blocking part 212 in an abutting mode.

With the above scheme, when water is required to be turned off, the user presses the pressing member 140 once, and the actuating member 400 drives the plug 300 to move to a corresponding position along the first direction, for example, a position where the second limiting table 321 and the blocking portion 212 are separated, and the driving portion 410 drives the plug 300 to rotate. After loosening, the first reset element 500 drives the plug 300 to move along the second direction to a position matched with the avoidance groove 211, for example, the position shown in fig. 8, the avoidance groove 211 plays a role in 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.

After the pressing member 140 is pressed once again, the actuating member 400 drives the plug 300 to move to a corresponding position along the first direction, for example, the second limiting platform 321 is separated from the avoiding groove 211, the driving portion 410 drives the plug 300 to rotate, and after the hand is loosened, the first reset member 500 drives the plug to move to a position matched with the blocking portion 212 along the second direction, for example, a position shown in fig. 9. The user can realize the normally open water outlet of the spray gun 1000 without holding the pressing member 140 long. Therefore, the spray gun 1000 has reasonable structural design, can improve the stability of the spray gun 1000 in a normally open or normally closed state, and has simple operation and convenient use.

Referring to fig. 10 and 11, in the embodiment of the present invention, a side of the driving part 410 facing the second limiting table 321 is provided with a fifth inclined surface 411. When the actuator 400 moves in the first direction, the second inclined surface 244 and the fourth inclined surface 322 are slidably engaged, so that the second limiting table 321 rotates. Therefore, when the pressing member 140 is pressed once, the driving portion 410 can drive the second limiting table 321 to rotate once, so that the second limiting table 321 is sequentially matched with the limiting groove or the blocking portion 212, and the spray gun 1000 is rapidly switched in a normally open state or a closed state, so that the operation is convenient and fast, and the user experience is good.

Referring to fig. 5 and 10, in the embodiment of the present invention, the outer circumferential 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 may be formed by a gap between the first protrusion 241 and the third protrusion 245 or by a sidewall at other positions of the water passage 210. The guide part 412 and the guide groove 250 are in guide fit, so that the direction of the actuating piece 400 is guided, the dislocation, the deflection and the like of the actuating piece 400 are effectively avoided, and the reliability of the spray gun 1000 is improved.

Referring to fig. 2 and 3, in the embodiment of the present invention, the inside of the water outlet 120 is provided with a guide post 123, the guide post 123 is provided with a through hole, one end of the actuating member 400, which is far away from the water outlet 122, is penetrated through the through hole, and one end of the pressing member 140 and the actuating member 400, which is penetrated through the through hole, are hinged. Further, the through hole can be communicated with the external space of the water outlet channel 121, the actuating member 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 through the through hole, the transmission rod 420 and the through hole are in sliding sealing through the second sealing ring, water leakage can be avoided, and the actuating member is simple in structure, low in manufacturing difficulty and high in assembly efficiency.

Referring to fig. 7, in the embodiment of the present invention, the plug 300 is provided with the overflow plate 350 on a side facing the water outlet 122, and the peripheral wall of the overflow plate 350 is provided with the overflow grooves 351, for example, the overflow grooves 351 are provided in plurality and are arranged at intervals along the circumferential direction of the overflow plate 350. When the spray gun 1000 is required to discharge water, the plug 300 gradually moves from a position abutting against the inner wall of the water outlet 220 to a position separated from the inner wall of the water outlet 220. For example, the stopper 300 gradually moves under the driving of the actuator 400. The water mainly enters the water flow channel through the flow groove 351, and the water flow area is smaller at the moment; when the plug 300 is at a position separated from the inner wall of the water passing hole 220, water mainly enters the water flow channel through the gap between the plug part 310 and the water passing body 200, and the water passing area is large, i.e. the water passing area is changed from small to large.

The second reset element 510 is sleeved on the transmission rod 420, one end of the second reset element 510 is abutted against the limiting part 413, and the other end is abutted against one end of the guide post 123. When the pressing member 140 is pressed and the hand is released, the second reset member 510 can drive the actuating member 400 to move along the second direction, so that the pressing member 140 can be reset after the hand is released, and shaking of the pressing member 140 is reduced. For example, the second restoring member 510 may be a spring and is sleeved on the actuating member 400, and two ends of the spring respectively abut against the limiting portion 413 and the guiding post 123. Of course, the first reset element 500 may also be a silicone element, a rubber element, a tension spring, an electromagnetic valve, a motor, and the like, and may be capable of driving the actuating element 400 to move along the second direction.

Referring to fig. 10 and 11, in the embodiment of the present invention, a clamping groove 414 is formed on the transmission rod 420, and the clamping groove 414 is used for installing the third sealing ring. The transmission rod 420 penetrates through the plug 300, and the third sealing ring is in sliding sealing fit with the plug 300, so that water leakage can be effectively avoided. The transmission rod 420 is disposed through the plug 300, so that when the pressing member 140 is pressed, the actuating member 400 can move along the first direction to drive the plug 300 to move. The structural design is reasonable and the reliability is high.
