[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] As Figures 1 to 9 shown, a multifunctional one-key control water gun includes a gun body main body 1 and a water inlet pipe 2, and a main channel 11 is provided inside the gun body main body 1.

[0035] An automatic water spray adjusting component 3 capable of automatically adjusting the water spray under the impact of water pressure is provided at the front end of the main channel 11. That is, every time the switch (the valve piece 4 described later) of the water gun is opened, there will be a water flow impact, and the automatic water spray adjusting component 3 will automatically change the shape of the water spray once under the impact of this water flow, which will be described in detail later. An inlet 111 is provided at the rear end of the main channel 11, and a water supply port 21 is provided at the upper end of the water inlet pipe 2. Of course, the lower end of the water inlet pipe 2 can be connected to a water supply source such as a tap water pipe.

[0036] As Figure 3 、 Figure 4 shown, an inlet cavity 12 communicating the two is provided between the inlet 111 and the water supply port 21. That is, the water coming in from the water inlet pipe 2 first enters the inlet cavity 12 and then enters the main channel 11 inside the gun body main body 1 from the inlet 111. A valve piece 4 for switching on and off the inlet 111 and the water supply port 21, and a first reset elastic member 5 capable of elastically pressing the valve piece 4 against the inlet 111 are provided in the inlet cavity 12. Among them, the valve piece 4 is preferably a highly elastic valve piece, such as a silica gel valve piece or a rubber valve piece. The first reset elastic member 5 is preferably a spring.

[0037] As Figure 3 、 Figure 4 shown, the valve piece 4 divides the inlet cavity 12 into a front half cavity 121 and a rear half cavity 122. The inlet 111 and the water supply port 21 are both located in the front half cavity 121, and after the rear half cavity 122 is pressurized, the valve piece 4 can be pressed tightly against the inlet 111. After the rear half cavity 122 is depressurized, the water flow coming from the water supply port 21 can push open the valve piece 4 and directly enter the inlet 111.

[0038] A pilot hole 41 for communicating the front half cavity 121 and the rear half cavity 122 is provided on the valve piece 4. Of course, the pilot hole 41 is a relatively small hole, much smaller than the inlet 111. A pressure relief channel 13 communicating the rear half cavity 122 and the main channel 11 is provided, and a button assembly 6 for controlling its on and off is connected to the pressure relief channel 13.

[0039] After the button assembly 6 controls the closing of the pressure relief passage 13, a part of the high-pressure water flow coming from the water supply port 21 can enter the rear half cavity 122 through the pilot hole 41. However, the rear half cavity 122 is closed. Therefore, the pressure in the rear half cavity 122 gradually increases until water can no longer enter. At this time, the pressure in the rear half cavity 122 presses the valve plate 4 against the water inlet 111, thus achieving the effect of closing the water.

[0040] After the button assembly 6 controls the opening of the pressure relief passage 13, the water and air in the rear half cavity 122 flow along the pressure relief passage 13 to the main passage 11. The pressure in the rear half cavity 122 gradually decreases until the high-pressure water flow coming from the water supply port 21 can overcome the first reset elastic member 5 and push open the valve plate 4. After pushing open the valve plate 4, the high-pressure water flow coming from the water supply port 21 directly flows into the water inlet 111, thus achieving the function of opening the water.

[0041] As Figures 2 - 4 shown, the basic principle of the present invention is: using the button assembly 6 to control the on-off of the pressure relief passage 13. Using the on-off of the pressure relief passage 13 to control the opening and closing of the valve plate 4 (i.e., the switch of the water gun, i.e., the on-off of the water flow), and using the impact of the water flow to drive the automatic water spray adjustment assembly 3 to adjust the water spray by itself. Therefore, the present invention only needs to press the button assembly 6 to control the switch of the water gun and the adjustment of the water spray shape, and can achieve one-key control and single-hand control, with simple and convenient operation.

[0042] More specifically, a communication hole 131 for communicating the pressure relief passage 13 and the rear half cavity 122 is provided between the pressure relief passage 13 and the rear half cavity 122. The button assembly 6 includes a plug 61 located behind the communication hole 131 and capable of moving back and forth to open and close the communication hole 131, and a sleeve 62 fixed to the rear end of the gun body 1. A second reset elastic member 63 for elastically pressing the plug 61 backward is provided on the front side of the plug 61. A connecting shaft 64 is provided on the plug 61, and a spring disk 65 slidably connected to the inside of the sleeve 62 along the front and rear directions is provided on the connecting shaft 64. A locking member 66 is provided in the sleeve 62, a pressing sleeve 67 is sleeved on the locking member 66, a third reset elastic member 68 is provided between the rear side of the spring disk 65 and the locking member 66, a locking structure for defining the front and rear positions of the locking member 66 is provided between the locking member 66 and the sleeve 62, a one-way meshing structure for driving the locking member 66 to rotate unidirectionally is provided between the pressing sleeve 67 and the locking member 66, and a first circumferential limiting structure for restricting the circumferential rotation of the pressing sleeve 67 is provided between the pressing sleeve 67 and the sleeve 62.

[0043] Both the second reset elastic member 63 and the third reset elastic member 68 are preferably springs.

[0044] The elastic coefficient of the third reset elastic member 68 is greater than that of the second reset elastic member 63. When the third reset elastic member 68 is squeezed, the second reset elastic member 63 will also be squeezed, that is, the second reset elastic member 63 cannot rely on its own elastic force to overcome the elastic squeezing of the third reset elastic member 68 and expand and reset.

[0045] It should be noted that in the present invention, the structure composed of the sleeve 62, the locking member 66, the pressing sleeve 67 and the third reset elastic member 68 (i.e., the locking structure, the one-way meshing structure and the first circumferential limiting structure) is similar to the structure in an automatic ballpoint pen and can be referred to here. Of course, it will also be described in detail below.

[0046] More specifically, as Figure 4 、 Figure 7 shown, the locking structure includes a first guiding convex tooth 621, a second guiding convex tooth 622 and a first locking groove 623 that are distributed at intervals on the inner side wall of the sleeve 62 in a circle. The front end faces of the first guiding convex tooth 621 and the second guiding convex tooth 622 are both inclined surfaces that gradually rise in the clockwise direction. And a second locking groove 624 is formed between the first guiding convex tooth 621 and the second guiding convex tooth 622. The locking structure further includes a plurality of locking convex teeth 661 provided on the outer side wall of the locking member 66, and the locking convex teeth 661 can cooperate with the first locking groove 623 and the second locking groove 624 in sequence. Of course, the depths of the first locking groove 623 and the second locking groove 624 in the front-rear direction are different, which means that when the locking member 66 cooperates with the first locking groove 623 and the second locking groove 624, the length of the locking member 66 protruding forward is different. After each pressing of the pressing sleeve 67 and then releasing, under the guiding action of the front end faces (inclined surfaces) of the first guiding convex tooth 621 and the second guiding convex tooth 622, the locking convex teeth 661 always stay in the first locking groove 623 or the second locking groove 624 alternately.

[0047] More specifically, as Figure 4 、 Figure 7 shown, the one-way meshing structure includes a triangular meshing tooth 671 provided at the front end of the pressing sleeve 67, and a plurality of one-way teeth 662 provided on the locking member 66 that can mesh with the meshing tooth 671. The end faces of the one-way teeth 662 gradually rise in the counterclockwise direction, that is, the end faces of the one-way teeth 662 are inclined surfaces. The cooperation between the meshing tooth 671 and the one-way teeth 662 can ensure the one-way rotation of the locking member 66. And the mutual extrusion between the tip of the meshing tooth 671 and the end face (inclined surface) of the one-way teeth 662 can provide a guiding acting force for the rotation of the locking member 66.

[0048] More specifically, as Figure 4 、 Figure 7As shown, the first circumferential limiting structure includes a limiting groove 625 provided on the inner side wall of the sleeve 62 and arranged in the front-rear direction, and a limiting protrusion 672 provided on the outer side wall of the pressing sleeve 67 and capable of being inserted into the limiting groove 625 and sliding back and forth therein.

[0049] More specifically, as Figures 2 - 6 , Figures 8 - 9 As shown, the automatic water splash adjustment assembly 3 includes a water spray head 31 fixed to the front end of the gun body 1. A plurality of different water spray channels 311 are provided on the water spray head 31. A end cap 37 is provided at the front end of the water spray head 31. The end cap 37 is provided with a plurality of water spray openings 371 with different water splashes and communicating with the corresponding water spray channels 311. A piston 32 capable of automatically moving forward under the impact of water pressure is provided between the water spray head 31 and the front end of the main channel 11. A water passing hole 321 is provided on the piston 32. A transmission structure for converting the forward and backward movement of the piston 32 into its circumferential rotation is provided between the piston 32 and the water spray head 31; and during the rotation of the piston 32, the water passing hole 321 communicates with different water spray channels 311, so as to spray water splashes of different shapes from different water spray openings 371.

[0050] As Figure 2 , Figure 3 As shown, a first elastic soft rubber gasket 36 is provided between the piston 32 and the water spray head 31 for preventing water leakage, buffering and reducing impact noise. The first elastic soft rubber gasket 36 is fixed on the piston 32, and through holes 361 corresponding to the water passing holes 321 one by one are also provided on the piston 32.

[0051] As Figure 2 , Figure 3 As shown, a number of different water spray openings 371 are provided on the end cap 37 at the front end of the water spray head 31 (the water spray openings 371 are divided into several types such as water spray openings 371a, water spray openings 371b and water spray openings 371c, etc.), and different water splash shapes can be sprayed. After the water gun is opened, the water passing hole 321 communicates with different water spray channels 311, and the water coming from the water spray channels 311 is then sprayed out from the corresponding water spray openings 371, so as to spray different water splashes.

[0052] A second elastic soft rubber gasket 38 is provided between the end cap 37 and the water spray head 31.

[0053] More specifically, as Figures 2 - 6 , Figures 8 - 9 As shown, the transmission structure includes a limiting post 33 provided between the water spray head 31 and the piston 32 and slidably connected to the water spray head 31 in the front-rear direction, and a fourth reset elastic member 34 for pressing the limiting post 33 backward. A front clutch tooth 331 is provided at the rear end of the limiting post 33. A rear clutch tooth 322 capable of meshing with the front clutch tooth 331 is provided in the middle of the front end of the piston 32. The fourth reset elastic member 34 is preferably a spring.

[0054] As shown in Figure 8 , Figure 9 As shown, a guide rail cover 35 is connected to the rear end of the water spray head 31. A guide rail groove 3a is formed in a circle between the guide rail cover 35 and the water spray head 31. The guide rail groove 3a includes a plurality of axially distributed axial grooves 3a1 arranged at intervals, and inclined guide grooves 3a2 connected between the front end of one axial groove 3a1 and the rear end of another adjacent axial groove 3a1. A slider 323 capable of moving in the guide rail groove 3a is provided on the outer side wall of the piston 32. As shown in Figure 9 As shown, the width of the rear end of the axial groove 3a1 is wider than that of its front end (the rear end of the axial groove 3a1 is wider by about half a tooth position in the direction of the inclined guide groove 3a2. The tooth position refers to the tooth positions of the front clutch teeth 331 and the rear clutch teeth 322). When the slider 323 is located at the front end of the axial groove 3a1, it can only move back and forth. When the slider 323 is located at the rear end of the axial groove 3a1, it can rotate clockwise by a certain angle (the clockwise direction is when looking from the front to the back, and the rotation angle is about half a tooth position). When the slider 323 is at the front end of the axial groove 3a1, the front clutch teeth 331 and the rear clutch teeth 322 are staggered and cannot be fully engaged. When the slider 323 reaches the rear end of the axial groove 3a1, due to the increased width, the piston 32 rotates clockwise (in the direction of the inclined guide groove 3a2) so that the front clutch teeth 331 and the rear clutch teeth 322 are fully engaged. That is, when the slider 323 is inserted at the rear end of the axial groove 3a1, the front clutch teeth 331 and the rear clutch teeth 322 can be fully engaged, but they are fully engaged after rotating clockwise by an angle. At this time, if the slider 323 moves forward, it will just cut into the inclined guide groove 3a2.

[0055] In the initial state, under the action of the fourth reset elastic member 34, the piston 32 moves to the rear side, that is, the slider 323 is at the rear end of the axial groove 3a1. At this time, the water through hole 321 on the piston 32 just aligns and communicates with one of the water spray channels 311. When starting to spray water, under the impact of the water flow, the piston 32 moves forward. When passing through the inclined guide groove 3a2, the slider 323 cuts into the inclined guide groove 3a2. Under the impact of the water flow, the piston 32 continues to move forward, and the slider 323 will move along the inclined guide groove 3a2. Under the guiding action of the inclined guide groove 3a2, the piston 32 will rotate while moving forward. As shown in Figure 9 As shown, when looking from the front to the back, the piston 32 will rotate clockwise. The slider 323 moves forward until it enters another axial groove 3a1 and reaches its front end. At this time, the water through hole 321 on the piston 32 just aligns and communicates with another water spray channel 311, thereby realizing the automatic switching of the water spray.

[0056] After the water is turned off and the water pressure disappears, under the action of the fourth reset elastic member 34, the piston 32 moves to the rear end of the axial groove 3a1, thus automatically resetting. During the movement, when the slider 323 moves to the inclined guide groove 3a2 (the rear end of the axial groove 3a1), the width of the axial groove 3a1 becomes wider, and the piston 32 will rotate a certain arc slightly in the direction of the inclined guide groove 3a2 under the circumferential component force of the extrusion force between the front clutch tooth 331 and the rear clutch tooth 322. At this time, the front clutch tooth 331 and the rear clutch tooth 322 are completely engaged. When the water is turned on again, the piston 32 moves forward, and a small part of the slider 323 will just fall on the front inclined surface of the inclined guide groove 3a2, so that the slider 323 enters the inclined guide groove 3a2, and then guides and drives the piston 32 to rotate while moving forward.

[0057] More specifically, as Figures 2 - 4 , Figures 8 - 9 shown, one side of the front end of the slider 323 is provided with a guide inclined surface 3231 to make the slider 323 slide more smoothly in the guide rail groove 3a.

[0058] More specifically, as Figures 2 - 4 , Figure 9 shown, a second circumferential limiting structure for restricting the rotation of the limiting column 33 is provided between the limiting column 33 and the water spray head 31. The second circumferential limiting structure preferably includes a limiting convex rib provided on the outer side wall of the limiting column 33. A jack is provided in the middle of the water spray head 31. The limiting column 33 is inserted into the jack from back to front. A limiting groove is provided on the inner side wall of the jack. The above-mentioned limiting convex rib can be inserted into the limiting groove and slide back and forth.

[0059] Preferably, as Figures 2 - 4 , Figures 8 - 9 shown, the guide rail cover 35 is detachably connected to the rear end of the water spray head 31 for easy assembly.

[0060] The use process of the present invention is specifically as follows:

[0061] Initially, under the action of the first reset elastic member 5, the valve plate 4 elastically presses against the water inlet 111.

[0062] Water off state: Press the pressing sleeve 67 once and release it. The pressing sleeve 67, the locking member 66 and the plug 61 will all move forward a certain distance and stay. At this time, the plug 61 blocks the communication hole 131, so that the rear half cavity 122 forms a sealed cavity. The water coming in from the water inlet pipe 2 first enters the front half cavity 121, and then slowly flows into the rear half cavity 122 through the pilot hole 41. Since the rear half cavity 122 is a sealed cavity, the pressure inside it slowly increases, causing the valve plate 4 to expand and deform and tightly adhere to the water inlet 111, thus blocking the water inlet 111. At this time, the water flow cannot flow, which is the water off state.

[0063] Boiling water state: Press the pressing sleeve 67 once again and then release it. Both the pressing sleeve 67 and the locking member 66 will rebound backward, and the plug 61 will also move backward under the elastic action of the second reset elastic member 63 to disengage from the communication hole 131, that is, the communication hole 131 is opened, the rear half cavity 122 is communicated with the pressure relief channel 13, and the water in the rear half cavity 122 can flow along the pressure relief channel 13 to the front end of the main channel 11, thereby realizing the pressure relief of the rear half cavity 122. After the pressure in the rear half cavity 122 decreases, the valve piece 4 no longer expands. The water supply flow in the front half cavity 121 has a large enough pressure, and this flow pushes the valve piece 4 to move backward, compressing the first reset elastic member 5, and the valve piece 4 opens the water inlet 111. The water supply flow in the front half cavity 121 directly surges into the main channel 11 from the water inlet 111 and finally sprays out from the corresponding spray nozzle 371 through the spray head 31.

[0064] Regarding the automatic adjustment of the water spray pattern: Each time the water is switched from the closed state to the boiling water state, the water flow will surge into the main channel 11, forming a certain impact force. This impact force acts on the piston 32, causing the piston 32 to move forward. During the forward movement of the piston 32, it will rotate a certain angle under the action of the above transmission structure, and the water passing hole 321 on the piston 32 will be connected to different spray channels 311, and then spray out from the corresponding spray nozzles 371, thereby spraying water sprays of different shapes. After the water is turned off, the piston 32 will automatically reset backward.

[0065] Obviously, whether it is boiling water or turning off the water, only need to press the pressing sleeve 67 once and then release it, that is, one-key control. For example, after pressing the pressing sleeve 67 once and releasing it, water will be sprayed; press it again and release it, and the water will be turned off; press it again and release it, and water will be sprayed again, and the shape of the water spray will also change.

[0066] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
