Description

Technical Field

[0001] The invention relates to the technical field of water guns, and in particular to a two-stage pressing one-button controlled water gun. Background Art

[0002] Water guns have become an indispensable tool for cleaning various objects. However, the design of traditional water guns has some ergonomic defects, which brings many inconveniences to users. When using a water gun for spray cleaning, users often need to frequently turn on and off the water gun and switch different water spray shapes according to the differences in the cleaning objects and the stubbornness of the stains, such as switching from a concentrated and strong direct water flow to a soft and dispersed spray. In actual operation, this often requires the user to use both hands, one hand holding the water gun for spraying, and the other hand to operate the switch and water spray shape adjustment device on the water gun. However, in many cases, the user may need to free up one hand to fix or operate the object being cleaned, or to pick up other cleaning tools at the same time, and at this time, both hands cannot be freed to operate the water gun.

[0003] For example, Chinese patent document CN103433167A discloses a water gun, the switching of which needs to be achieved by rotating the nozzle or pressing a specific button, which undoubtedly requires the cooperation of both hands and is cumbersome to operate. This design will cause great inconvenience and trouble to users in scenarios that require one-handed operation, such as cleaning high objects, cleaning the bottom of a vehicle, or cleaning in a narrow space, and reduce cleaning efficiency.

[0004] The applicant previously disclosed a multifunctional one-button controlled water gun in patent CN220759627U, attempting to solve the above problems. The water gun attempts to integrate multiple functions through a single button to simplify the operation process. However, the technical solution disclosed in the patent still has shortcomings. Although its single-button control design improves the convenience of operation to a certain extent, the operating feel of the button itself is poor, especially when switching the shape of the water splash. It is difficult for users to accurately judge whether the button is pressed in place by feel, which leads to misoperation and affects the user experience.

[0005] Therefore, the design of the water gun still needs to be further improved to provide a more convenient, efficient and user-friendly operating experience. The present invention is made based on this situation. Summary of the invention

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figures 1 to 8 The two-stage push-type one-button controlled water gun shown comprises a gun body 1 and a water inlet pipe 2 , wherein a main channel 11 is provided in the gun body 1 .

[0033] Waterway structure:

[0034] The front end of the main channel 11 is provided with an automatic water splash adjustment component 3 that can automatically adjust the water splash under the impact of water pressure. That is, every time the switch of the water gun (the valve plate 4 described later) is turned on, there will be a water flow impact. The automatic water splash adjustment component 3 will automatically change the shape of the water splash once under the impact of the water flow, which will be described in detail later. The rear end of the main channel 11 is provided with a water inlet 111, and the upper end of the water inlet pipe 2 is provided with a water supply port 21, and the water supply pressure is usually above 5PSI. 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.

[0035] A water inlet cavity 12 is provided between the water inlet 111 and the water supply port 21 to connect the two, that is, the water coming in from the water inlet pipe 2 first enters the water inlet cavity 12, and then enters the main channel 11 in the gun body 1 from the water inlet 111. The water inlet cavity 12 is provided with a valve plate 4 for opening and closing the water inlet 111 and the water supply port 21, and a first resetting elastic member 5 that can elastically press the valve plate 4 against the water inlet 111. The valve plate 4 is preferably a highly elastic valve plate, such as a silicone valve plate or a rubber valve plate. The first resetting elastic member 5 is preferably a spring.

[0036] The valve plate 4 divides the water inlet chamber 12 into a front chamber 121 and a rear chamber 122, and the water inlet 111 and the water supply port 21 are both located in the front chamber 121. After the rear chamber 122 is pressurized, the valve plate 4 can be pressed against the water inlet 111. After the rear chamber 122 is depressurized, the water flow from the water supply port 21 can flush the valve plate 4 and directly enter the water inlet 111.

[0037] The valve plate 4 is provided with a pilot hole 41 for connecting the front chamber 121 and the rear chamber 122. Of course, the pilot hole 41 is a relatively small hole, much smaller than the water inlet 111. A pressure relief channel 13 is provided between the rear chamber 122 and the main channel 11 to connect the two, and a connecting hole 131 is provided between the pressure relief channel 13 and the rear chamber 122 to connect the two. A button assembly 6 for controlling the on and off of the connecting hole 131 is provided at the connecting hole 131.

[0038] It is worth noting that, in order to ensure normal pressure relief, the aperture of the pilot hole 41 is smaller than that of the pressure relief channel 13 .

[0039] After the button assembly 6 controls the pressure relief channel 13 to be closed, part of the high-pressure water flow from the water supply port 21 can enter the rear chamber 122 through the pilot hole 41, but the rear chamber 122 is closed, so the pressure in the rear chamber 122 gradually increases until no more water can enter. At this time, the pressure in the rear chamber 122 presses the valve plate 4 against the water inlet 111, thereby achieving the water shut-off effect.

[0040] After the button assembly 6 controls the pressure relief channel 13 to open, the water and air in the rear half chamber 122 flow along the pressure relief channel 13 to the main channel 11, and the pressure in the rear half chamber 122 gradually decreases until the high-pressure water flow from the water supply port 21 can overcome the first reset elastic member 5 and flush open the valve plate 4. After flushing open the valve plate 4, the high-pressure water flow from the water supply port 21 directly flows into the water inlet 111, thereby realizing the water boiling function.

[0041] The basic working principle of the present invention is: the button assembly 6 is used to control the on and off of the pressure relief channel 13. The on and off of the pressure relief channel 13 is used to control the switch of the valve plate 4 (i.e. the switch of the water gun, i.e. the on and off of the water flow), and the impact of the water flow is used to drive the automatic water splash adjustment assembly 3 to adjust the water splash 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 splash shape, which can realize one-button control, single-hand control, and simple and convenient operation.

[0042] Button components and working principles:

[0043] The main innovation of the present invention is to improve the button assembly 6. The button assembly 6 includes a plug 61 located behind the connecting hole 131 and capable of opening and closing the connecting hole 131. The plug 61 is connected to a first-level button 67 for driving it to move forward and backward. An elastic self-locking structure is provided on the first-level button 67. It is worth noting that in the present invention, the elastic self-locking structure is similar to the button structure of an automatic ballpoint pen, which can be pressed to lock and pressed again to unlock, which can be used as a reference here and will be described in detail later.

[0044] The primary button 67 is sleeved with a secondary button 7 which is always in contact with the primary button 67, and a damping seat 8 is disposed on the periphery of the primary button 67. An elastic damping member 81 for elastically pressing the damping seat 8 outward is disposed between the damping seat 8 and the gun body 1. The elastic damping member 81 is preferably a spring.

[0045] like Figure 4 As shown, when the water gun is turned on and the secondary button 7 is not pressed, there is a gap H between the damping seat 8 and the inner end of the secondary button 7. When the secondary button 7 is pressed, the secondary button 7 first only presses the primary button 67 inwards, and after moving inwards for a distance H, the secondary button 7 contacts the damping seat 8 and presses the primary button 67 and the damping seat 8 inwards at the same time.

[0046] That is, there are two stages of damping when pressing the secondary button 7, the first stage has a smaller damping, and the second stage has a larger damping, which can improve the hand feel. More importantly, it is judged whether the specific position is pressed through hand feel feedback. The specific position means that the water splash can be adjusted without turning the water on or off.

[0047] Specifically, driving the automatic water splash regulating component 3 to regulate the water splash only requires an instantaneous water flow impact, that is, only the plug 61 needs to be temporarily closed and then opened. In the case of boiling water (when boiling water, the first-level button 67 pops out), the second-level button 7 (the second-level button 7 and the first-level button 67 always act synchronously) only needs to be pressed to about half (pressing distance H), and under the action of the third reset elastic member 68 (described in detail later), the plug 61 has contacted and blocked the connecting hole 131. However, since the self-locking position has not been reached, the elastic self-locking structure has not yet formed self-locking (self-locking will only be formed when the second-level button 7 and the first-level button 67 are pressed to the bottom). At this time, if you release your hand and stop pressing, the plug 61 will reset and open the connecting hole 131 again. The water pressure during this instantaneous opening process will drive the automatic water splash regulating component 3 to regulate the water splash. Since the elastic self-locking structure has not yet formed self-locking during this process, the water will not be completely turned off.

[0048] That is to say, pressing the secondary button 7 to about halfway (the specific pressing distance is H) can adjust the water splash, and pressing it completely can turn off the water. The damping is small in the first half, and large in the second half, and the hand feel is obviously different. Therefore, in the state of boiling water, when pressing the secondary button 7, if you feel a significant change in damping, you can release your hand to switch the water splash without turning off the water.

[0049] Furthermore, in order to prevent the secondary button 7 from detaching, the damping seat 8 is provided with a limiting sleeve 82 that is sleeved on the secondary button 7, and the inner wall of the outer end of the limiting sleeve 82 is provided with a first limiting step 821, and the outer wall of the inner end of the secondary button 7 is provided with a second limiting step 71 that can cooperate with the first limiting step 821.

[0050] The two-stage pressing control is summarized as follows:

[0051] First stroke (splash adjustment): When the water gun is turned on, lightly press the secondary button 7 to move it a distance H, at which time the secondary button 7 contacts the damping seat 8. During this process, the pressure of the third reset elastic member 68 is sufficient to temporarily close the connecting hole 131 with the plug 61. Since the self-locking position has not been reached, after releasing the secondary button 7, the plug 61 is reset under the action of the elastic member, and the connecting hole 131 is opened again. This opening process causes an instantaneous water pressure change, driving the automatic splash adjustment component 3 to change the shape of the splash.

[0052] Second stroke (water flow switch): Continue to press the secondary button 7 to overcome the resistance of the elastic damping member 81, and press the primary button 67 and the damping seat 8 together. At this time, the elastic self-locking structure is activated, the plug 61 is locked in the position of closing the connecting hole 131, the pressure relief channel 13 is cut off, the pressure in the rear chamber 122 increases, the valve plate 4 is closed, and the water flow stops. Press the secondary button 7 again, the elastic self-locking structure is unlocked, the plug 61 is reset, and the water flow is restarted.

[0053] The present invention realizes one-touch control of water flow switch and water splash shape adjustment through a two-stage push button assembly. The operation is simple and all operations can be completed with one hand. In addition, the two-stage press has obvious damping feedback, the operation feel is strong, and the user experience is significantly improved.

[0054] The following is a detailed description of the remaining structures:

[0055] Furthermore, the elastic self-locking structure includes a second reset elastic member 63 which is arranged at the front side of the plug 61 and is used to elastically press the plug 61 backwards, a connecting shaft 64 is provided on the plug 61, a spring disk 65 which is slidably connected to the sleeve 62 along the front and rear is provided on the connecting shaft 64, a locking member 66 is provided in the sleeve 62, and the first-level button 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 sleeve 62 is provided at the rear end of the gun body 1, a locking structure for limiting the front and rear position of the locking member 66 is provided between the locking member 66 and the sleeve 62, a unidirectional meshing structure for driving the locking member 66 to rotate unidirectionally is provided between the first-level button 67 and the locking member 66, and a first circumferential limiting structure for limiting the circumferential rotation of the first-level button 67 is provided between the first-level button 67 and the sleeve 62.

[0056] The second resetting elastic member 63 and the third resetting elastic member 68 are preferably springs. The elastic coefficient of the third resetting elastic member 68 is greater than the elastic coefficient of the second resetting elastic member 63. When the third resetting elastic member 68 is squeezed, the second resetting elastic member 63 will also be squeezed, that is, the second resetting elastic member 63 cannot rely on its own elastic force to overcome the elastic squeezing of the third resetting elastic member 68 and relax and reset.

[0057] Further, the locking structure includes a circle of first guide protruding teeth 621, second guide protruding teeth 622 and first locking grooves 623 alternately distributed on the inner side wall of the sleeve 62, the front end faces of the first guide protruding teeth 621 and the second guide protruding teeth 622 are inclined surfaces that gradually rise in the clockwise direction, and the first guide protruding teeth 621 and the second guide protruding teeth 622 form a second locking groove 624, and the locking structure also includes a plurality of locking protruding teeth 661 provided on the outer side wall of the locking member 66, and the locking protruding teeth 661 can sequentially cooperate with the first locking groove 623 and the second locking groove 624. Of course, the first locking groove 623 and the second locking groove 624 have different depths in the front-to-back direction, 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 extending forward is different. Each time after the first-level button 67 is pressed and released, under the guiding action of the front end faces (inclined surfaces) of the first guide protruding tooth 621 and the second guide protruding tooth 622, the locking protruding tooth 661 always stays in the first locking groove 623 or the second locking groove 624 in turn.

[0058] Furthermore, the one-way meshing structure includes a circle of triangular meshing teeth 671 arranged at the front end of the first-level button 67, and a plurality of one-way teeth 662 arranged on the locking member 66 and capable of meshing with the meshing teeth 671. The end faces of the one-way teeth 662 are gradually raised in the counterclockwise direction, that is, the end faces of the one-way teeth 662 are inclined. The cooperation of the meshing teeth 671 and the one-way teeth 662 can ensure the one-way rotation of the locking member 66. In addition, the mutual extrusion of the tooth tips of the meshing teeth 671 and the end faces (inclined faces) of the one-way teeth 662 can provide a guiding force for the rotation of the locking member 66.

[0059] Furthermore, the first circumferential limiting structure includes a limiting groove 625 provided on the inner wall of the sleeve 62 and arranged along the front-to-back direction, and a limiting protrusion 672 provided on the outer wall of the first-level button 67 and capable of being inserted into the limiting groove 625 and sliding forward and backward therein.

[0060] Furthermore, the automatic water splash adjustment component 3 includes a water spray head 31 fixed to the front end of the gun body 1, the water spray head 31 is provided with a plurality of different water spray channels 311, the front end of the water spray head 31 is provided with an end cover 37, the end cover 37 is provided with a plurality of water spray ports 371 with different water splashes and connected to the corresponding water spray channels 311, a piston 32 that can automatically move forward under water pressure impact is provided between the water spray head 31 and the front end of the main channel 11, the piston 32 is provided with a water hole 321, and 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. During the rotation of the piston 32, the water hole 321 is connected to different water spray channels 311 to spray water splashes of different shapes.

[0061] Furthermore, the transmission structure includes a limit post 33 disposed between the water spray head 31 and the piston 32 and slidably connected to the water spray head 31 along the front-to-back direction, and a fourth reset elastic member 34 that presses the limit post 33 backwards, a front clutch tooth 331 is disposed at the rear end of the limit post 33, and a rear clutch tooth 322 that can mesh with the front clutch tooth 331 is disposed at the middle of the front end of the piston 32. The fourth reset elastic member 34 is preferably a spring.

[0062] The rear end of the water spray head 31 is connected to a guide cover 35, and a circle of guide grooves 3a are formed between the guide cover 35 and the water spray head 31. The guide groove 3a includes a plurality of axial grooves 3a1 distributed alternately, and an inclined guide groove 3a2 connected between the front end of the axial groove 3a1 and the rear end of another adjacent axial groove 3a1, and a slider 323 that can move in the guide groove 3a is provided on the outer wall of the piston 32. The width of the rear end of the axial groove 3a1 is wider than that of the 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, and the tooth position refers to the tooth position of the front clutch tooth 331 and the rear clutch tooth 322), and the slider 323 can only move forward and backward when it is located at the front end of the axial groove 3a1, and can rotate clockwise by a certain angle when it is located at the rear end of the axial groove 3a1 (the clockwise direction is viewed 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 widening of the width, the piston 32 rotates in the direction of the inclined guide groove 3a2 (clockwise) to make the front clutch teeth 331 and the rear clutch teeth 322 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 will be fully engaged after rotating clockwise for an angle. At this time, if the slider 323 moves forward, it will just cut into the inclined guide groove 3a2.

[0063] In the initial state, under the action of the fourth resetting 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 hole 321 on the piston 32 is just aligned and connected to one of the water spray nozzles 311. When the water spray is turned on, the piston 32 moves forward under the impact of the water flow, and 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 guidance of the inclined guide groove 3a2, the piston 32 will move forward and rotate at the same time. From the front to the back, the piston 32 will rotate clockwise. The slider 323 moves forward to enter another axial groove 3a1 and reaches its front end. At this time, the water hole 321 on the piston 32 is just aligned and connected to another water spray nozzle 311, thereby realizing the automatic switching of the water spray.

[0064] After the water is turned off, the water pressure disappears, and under the action of the fourth reset elastic member 34, the piston 32 moves to the rear end of the axial groove 3a1, thereby 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 widens, and the piston 32 slightly rotates a certain arc in the direction of the inclined guide groove 3a2 under the circumferential component of the extrusion force of the front clutch tooth 331 and the rear clutch tooth 322, and the front clutch tooth 331 and the rear clutch tooth 322 are fully engaged. When the water is turned on again, the piston 32 moves forward, and a small part of the slider 323 just falls 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 the piston 32 to rotate while moving forward.

[0065] More specifically, a guide slope 3231 is provided on one side of the front end of the slider 323 so that the slider 323 can slide more smoothly in the guide groove 3a.

[0066] More specifically, a second circumferential limiting structure for limiting 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 ridge provided on the outer wall of the limiting column 33, a plug hole is provided in the middle of the water spray head 31, the limiting column 33 is inserted into the plug hole from back to front, and a limiting groove is provided on the inner wall of the plug hole, and the above-mentioned limiting ridge can be inserted into the limiting groove and slide forward and backward.

[0067] Preferably, the guide rail cover 35 is detachably connected to the rear end of the sprinkler head 31 for easy assembly.

[0068] For any unfinished matters, please refer to the patent CN220759627U previously applied for by the applicant, which will not be elaborated here.
