Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of water gun, especially to a two-section press type one-key control water gun. BACKGROUND

[0002] In cleaning various objects, the water gun has become an indispensable tool. However, the design of the traditional water gun has some defects in the aspect of ergonomics, which brings many inconveniences to the user. During the process of using the water gun to spray and clean, the user often needs to frequently turn on and off the water gun and switch different water spray shapes according to the differences of the cleaning objects and the stubbornness of the stains, for example, from switching the concentrated strong straight jet to the soft dispersed spray. This often needs to occupy the user's both hands in actual operation, one hand holds the water gun to spray, and the other hand needs to operate the switch and water spray shape adjusting device on the water gun. However, in many cases, the user may need to free one hand to fix or operate the cleaned object, or take other cleaning tools at the same time, at this time, it is impossible to free both hands to control the water gun.

[0003] For example, Chinese patent document CN103433167A discloses a water gun, the switching of the water spray shape of which needs to be realized by rotating the spray head or pressing a specific button, which undoubtedly needs the cooperation of both hands, and the operation is relatively cumbersome. Such design will bring great inconvenience and trouble to the user and reduce the cleaning efficiency in the scene that needs one-handed operation, such as cleaning high objects, cleaning the bottom of the vehicle or cleaning in a narrow space.

The water gun tried to integrate multiple functions through a single key to simplify the operation process. However, the technical solution disclosed in this patent still has deficiencies. Although the single key control design improves the convenience of operation to a certain extent, the operation feeling of the key itself is not good, especially when switching the water spray shape, the user cannot accurately judge whether the key is pressed in place through the feeling, which leads to misoperation and affects the use experience.

[0005] Therefore, it is still necessary to further improve the design of the water gun to provide a more convenient, efficient and user-friendly operation experience. The utility model is made on the basis of this situation. UTILITY MODEL CONTENT

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

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

[0033] Waterway structure:

[0034] The main channel 11 is equipped with an automatic water flow adjustment component 3 at its front end, which automatically adjusts the water flow pattern under water pressure impact. That is, each time the water gun is turned on (the valve plate 4 mentioned later), a water flow impact occurs, and the automatic water flow adjustment component 3 automatically changes the water flow pattern under this impact, as will be described in detail later. The main channel 11 has an inlet 111 at its rear end, and the inlet pipe 2 has a supply outlet 21 at its upper end. The supply water pressure is typically above 5 PSI. Of course, the lower end of the inlet pipe 2 can be connected to a water source such as a tap water pipe.

[0035] The water inlet 111 and the water supply port 21 are connected by a water inlet cavity 12, that is, the water entering 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 piece 4 for opening and closing the water inlet 111 and the water supply port 21, and a first reset elastic member 5 capable of elastically pressing the valve piece 4 on the water inlet 111. Among them, the valve piece 4 is preferably a high-elasticity valve piece, such as a silica gel valve piece or a rubber valve piece. The first reset elastic member 5 is preferably a spring.

[0036] The valve piece 4 divides the water inlet cavity 12 into a front half cavity 121 and a rear half cavity 122, and the water inlet 111 and the water supply port 21 are both located in the front half cavity 121. The rear half cavity 122 can press the valve piece 4 tightly on the water inlet 111 after being pressurized, and the water flow from the water supply port 21 can flush away the valve piece 4 to directly enter the water inlet 111 after the rear half cavity 122 is depressurized.

[0037] The valve piece 4 is provided with a pilot hole 41 for connecting the front half cavity 121 and the rear half cavity 122. Of course, the pilot hole 41 is a relatively small hole, much smaller than the water inlet 111. The rear half cavity 122 and the main channel 11 are connected by a pressure relief channel 13, and the pressure relief channel 13 and the rear half cavity 122 are connected by a communication hole 131, and the button assembly 6 is arranged at the communication hole 131 for controlling the opening and closing of the communication hole 131.

[0038] It is worth noting that in order to ensure normal pressure relief, the diameter 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 half cavity 122 through the pilot hole 41, but the rear half cavity 122 is closed, so the pressure in the rear half cavity 122 gradually increases until no water can enter, at this time, the pressure in the rear half cavity 122 presses the valve piece 4 tightly on the water inlet 111, thereby realizing the water closing effect.

[0040] After the button assembly 6 controls the pressure relief channel 13 to be opened, the water and air in the rear half cavity 122 flow to the main channel 11 along the pressure relief channel 13, and the pressure in the rear half cavity 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 away the valve piece 4. After the valve piece 4 is flushed away, the high-pressure water flow from the water supply port 21 directly flows into the water inlet 111, thereby realizing the water opening function.

[0041] The basic working principle of the utility model is: using button assembly 6 to control the on-off of pressure relief channel 13. Using the on-off of pressure relief channel 13 to control the opening and closing of valve piece 4 (namely the opening and closing of the water gun, namely the on-off of water flow), using the impact of water flow to drive automatic water spray adjusting assembly 3 to adjust water spray automatically, therefore the utility model only needs to press button assembly 6 to control the opening and closing of the water gun and the adjustment of water spray shape, can realize one-key control, one-hand control, and is simple and convenient to operate.

[0042] Button assembly and working principle:

[0043] The main innovation of the utility model lies in improving button assembly 6. Button assembly 6 includes plug 61 located behind communication hole 131 and capable of opening and closing communication hole 131, plug 61 is connected with primary button 67 used for driving the front and back movement of plug 61. Primary button 67 is provided with elastic self-locking structure. It is worth noting that in the utility model, the elastic self-locking structure is similar to the button structure of automatic ballpoint pen, can realize press locking and re-press unlocking, which can be referred to here, and will be described in detail later.

[0044] Secondary button 7 is sleeved on primary button 67 and always abuts against primary button 67, damping seat 8 is arranged on the periphery of primary button 67, and elastic damping piece 81 is arranged between damping seat 8 and gun body main body 1 and used for elastically pressing outward. Elastic damping piece 81 is preferably spring.

[0045] As shown in the figure, Figure 4 When the water gun is in the opening state and the secondary button 7 is not pressed, the inner end of damping seat 8 and secondary button 7 has interval H. During the pressing of secondary button 7, secondary button 7 only presses primary button 67 inward at first, and when moving a distance H inward, secondary button 7 contacts damping seat 8 and simultaneously presses primary button 67 and damping seat 8 inward.

[0046] That is, there are two damping sections during the pressing of secondary button 7, the first damping section is smaller, and the second damping section is larger, the two damping sections can improve the hand feeling, and more importantly, the specific position can be judged by the hand feeling feedback. The specific position refers to the position that can adjust water spray without opening and closing.

[0047] Specifically, the automatic water spray adjusting assembly 3 only needs a momentary water flow impact to adjust the water spray, that is, only needs the plug 61 to be temporarily closed and then opened. In the case of boiling water (when the primary button 67 is popped out), the secondary button 7 (the secondary button 7 and the primary button 67 always act synchronously) only needs to be pressed to a position of about half the pressing distance H, and under the action of the third reset elastic member 68 (to be described later), the plug 61 has contacted and blocked the communication hole 131. Only because the self-locking position has not been reached, the elastic self-locking structure has not formed self-locking at this time (the elastic self-locking structure will form self-locking only when the secondary button 7 and the primary button 67 are pressed to the bottom), and the plug 61 will reset to open the communication hole 131 again when the hand is released and no longer pressed, and the water pressure in this momentary opening process will drive the automatic water spray adjusting assembly 3 to adjust the water spray. Because the elastic self-locking structure has not formed self-locking in this process, the water will not be completely turned off.

[0048] That is, the secondary button 7 is pressed to a position of about half the pressing distance H (the specific pressing distance is H) to adjust the water spray, and is completely pressed to the position to turn off the water. The front half of the pressing has small damping, and the back half has large damping, and the feeling is obviously different. Therefore, in the case of boiling water, if the damping changes obviously during the pressing of the secondary button 7, the hand is released to switch the water spray without turning off the water.

[0049] Further, in order to avoid the secondary button 7 from being detached, the damping seat 8 is provided with a limiting sleeve 82 sleeved on the secondary button 7, the outer end inner wall of the limiting sleeve 82 is provided with a first limiting step 821, and the inner end outer wall of the secondary button 7 is provided with a second limiting step 71 capable of cooperating with the first limiting step 821.

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

[0051] First-stage stroke (water spray adjustment): in the state of opening the water gun, the secondary button 7 is lightly pressed to move a distance H, and the secondary button 7 contacts the damping seat 8 at this time. During this process, the pressure of the third reset elastic member 68 is sufficient to temporarily close the communication hole 131 by the plug 61. Because the self-locking position has not been reached, after the secondary button 7 is released, the plug 61 resets under the action of the elastic member, and the communication hole 131 is opened again. The opening process causes a momentary change in water pressure, which drives the automatic water spray adjusting assembly 3 to change the water spray shape.

[0052] Second-stage stroke (water flow switch): the secondary button 7 is continuously pressed to overcome the resistance of the elastic damping member 81, and the primary button 67 and the damping seat 8 are pressed down at this time. At this time, the elastic self-locking structure is started, the plug 61 is locked in the position of closing the communication hole 131, the pressure relief channel 13 is cut off, the pressure in the rear half cavity 122 rises, the valve plate 4 is tightly closed, and the water flow stops. The secondary button 7 is pressed again, the elastic self-locking structure is unlocked, the plug 61 resets, and the water flow is opened again.

[0053] The utility model discloses a two-stage type pressing button assembly, realizes water flow switch and water spray shape adjustment one-key control, and operation is simple, and all operations can be completed by single hand, and two-stage pressing has obvious damping feedback, and the operation hand feeling is strong, and the user experience is improved obviously.

[0054] The following is the specific description of the remaining structure:

[0055] Further, the elastic self-locking structure includes a second reset elastic member 63 arranged on the front side of the plug 61 and used for elastically pressing the plug 61 backward, the plug 61 is provided with a connecting shaft 64, the connecting shaft 64 is provided with a spring disc 65 slidably connected in the sleeve 62, the sleeve 62 is provided with a locking member 66, the first button 67 is sleeved on the locking member 66, the spring disc 65 is provided with a third reset elastic member 68 between the rear side and the locking member 66, the rear end of the gun body 1 is provided with the sleeve 62, the locking member 66 and the sleeve 62 are provided with a locking structure for limiting the front and rear positions of the locking member 66, the first button 67 and the locking member 66 are provided with a one-way meshing structure for driving the locking member 66 to rotate in one direction, and the first button 67 and the sleeve 62 are provided with a first circumferential limiting structure for limiting the circumferential rotation of the first button 67.

[0056] Preferably, the second reset elastic member 63 and the third reset elastic member 68 are springs. 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 pressed, the second reset elastic member 63 will also be pressed, that is, the second reset elastic member 63 cannot rely on its own elastic force to overcome the elastic pressure of the third reset elastic member 68 and relax.

[0057] Further, the locking structure comprises a circle of first guide protrusions 621 and second guide protrusions 622 and a first locking groove 623 arranged on the inner side wall of the sleeve 62, the front end faces of the first guide protrusions 621 and the second guide protrusions 622 are inclined surfaces gradually rising in the clockwise direction, and the second locking groove 624 is formed between the first guide protrusions 621 and the second guide protrusions 622, the locking structure further comprises a plurality of locking protrusions 661 arranged on the outer side wall of the locking member 66, and the locking protrusions 661 can be matched with the first locking groove 623 and the second locking groove 624 in turn. Of course, the depths of the first locking groove 623 and the second locking groove 624 in the front-back direction are different, which means that the length of the locking member 66 protruding forward when matched with the first locking groove 623 and the second locking groove 624 is different. After each time the primary button 67 is pressed and released, under the guidance of the front end faces (inclined surfaces) of the first guide protrusions 621 and the second guide protrusions 622, the locking protrusions 661 always stay in the first locking groove 623 or the second locking groove 624 in turn.

[0058] Further, the one-way engagement structure comprises a circle of triangular engagement teeth 671 arranged at the front end of the primary button 67, and a plurality of one-way teeth 662 arranged on the locking member 66 and capable of being engaged with the engagement teeth 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 of the engagement teeth 671 and the one-way teeth 662 can ensure the one-way rotation of the locking member 66. Moreover, the mutual extrusion of the tooth tips of the engagement teeth 671 and the end faces (inclined surfaces) of the one-way teeth 662 can provide a guiding force for the rotation of the locking member 66.

[0059] Further, the first circumferential limiting structure comprises a limiting groove 625 arranged on the inner side wall of the sleeve 62 and arranged in the front-back direction, and a limiting protrusion 672 arranged on the outer side wall of the primary button 67 and capable of being inserted into the limiting groove 625 and sliding in the front-back direction therein.

[0060] Further, the automatic water spray adjusting assembly 3 comprises a water spraying head 31 fixed at the front end of the gun body 1, a plurality of different water spraying channels 311 are arranged on the water spraying head 31, an end cover 37 is arranged at the front end of the water spraying head 31, a plurality of water spraying ports 371 with different water sprays and communicating with the corresponding water spraying channels 311 are arranged on the end cover 37, a piston 32 capable of moving forward automatically under the impact of water pressure is arranged between the front end of the water spraying head 31 and the main channel 11, a water passing hole 321 is arranged on the piston 32, and a transmission structure for converting the forward-backward movement of the piston 32 into the circumferential rotation of the piston 32 is arranged between the piston 32 and the water spraying head 31. During the rotation of the piston 32, the water passing hole 321 communicates with different water spraying channels 311, so as to spray different shapes of water sprays.

[0061] Further, the transmission structure comprises a limiting column 33 arranged between the water spraying head 31 and the piston 32 and slidingly connected to the water spraying head 31 in the front-rear direction, and a fourth reset elastic member 34 for pressing the limiting column 33 rearward, wherein the rear end of the limiting column 33 is provided with front clutch teeth 331, and the middle part of the front end of the piston 32 is provided with rear clutch teeth 322 capable of intermeshing with the front clutch teeth 331. The fourth reset elastic member 34 is preferably a spring.

[0062] The rear end of the water spraying head 31 is connected with a guide rail cover 35, and a guide rail groove 3a is formed between the guide rail cover 35 and the water spraying head 31, wherein the guide rail groove 3a comprises a plurality of axially distributed axial grooves 3a1 and inclined guide grooves 3a2 connected between the front end of the axial groove 3a1 and the rear end of another adjacent axial groove 3a1, and the outer side wall of the piston 32 is provided with a sliding block 323 capable of moving in the guide rail groove 3a. The rear end of the axial groove 3a1 is wider than the front end, and the width of the rear end of the axial groove 3a1 is about half a tooth position wider than the direction of the inclined guide groove 3a2, wherein the tooth position refers to the tooth position of the front clutch teeth 331 and the rear clutch teeth 322. When the sliding block 323 is located at the front end of the axial groove 3a1, it can only move forward and backward, and when the sliding block 323 is located at the rear end of the axial groove 3a1, it can rotate by a certain angle clockwise (the clockwise direction is from front to rear, and the rotation angle is about half a tooth position). When the sliding block 323 is at the front end of the axial groove 3a1, the front clutch teeth 331 and the rear clutch teeth 322 are misaligned and cannot be completely meshed. When the sliding block 323 reaches the rear end of the axial groove 3a1, the width is widened, and the piston 32 rotates in the direction of the inclined guide groove 3a2 (clockwise direction) to make the front clutch teeth 331 and the rear clutch teeth 322 completely meshed. That is, when the sliding block 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 completely meshed, but after rotating by an angle clockwise, they are completely meshed again, and at this time, if the sliding block 323 advances, it will cut into the inclined guide groove 3a2.

[0063] 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 sliding block 323 is located at the rear end of the axial groove 3a1, and at this time, the water through hole 321 on the piston 32 is just aligned and connected to one kind of water spraying nozzle 311. When the water spraying is started, under the impact of the water flow, the piston 32 moves forward, and when passing through the inclined guide groove 3a2, the sliding block 323 cuts into the inclined guide groove 3a2. Under the impact of the water flow, the piston 32 continues to move forward, and the sliding block 323 will move along the inclined guide groove 3a2, and under the guidance of the inclined guide groove 3a2, the piston 32 will move forward while rotating. From front to rear, the piston 32 will rotate clockwise. The sliding block 323 moves forward to enter another axial groove 3a1 and reaches the front end thereof, and at this time, the water through hole 321 on the piston 32 is just aligned and connected to another water spraying nozzle 311, thereby realizing the automatic switching of the water spray.

[0064] When the water is off, the water pressure disappears, and the piston 32 moves to the rear end of the axial slot 3a1 under the action of the fourth reset elastic member 34, thereby automatically resetting. During the movement, when the slider 323 moves to the inclined guide slot 3a2 (rear end of the axial slot 3a1), the width of the axial slot 3a1 becomes wider, and the piston 32 will slightly rotate a certain radian in the direction of the inclined guide slot 3a2 under the action of the circumferential component force of the extrusion force of the front and rear clutch teeth 331 and 322, at this time, the front and rear clutch teeth 331 and 322 are completely engaged. When the water is turned on again, the piston 32 moves forward, and the slider 323 will just have a small part falling on the front inclined surface of the inclined guide slot 3a2, so that the slider 323 enters the inclined guide slot 3a2, thereby guiding and driving the piston 32 to move forward while rotating.

[0065] More specifically, one side of the front end of the slider 323 is provided with a guide inclined surface 3231, so that the slider 323 slides more smoothly in the guide rail slot 3a.

[0066] More specifically, a second circumferential limiting structure for limiting the rotation of the limiting column 33 is arranged between the limiting column 33 and the water spraying head 31. The second circumferential limiting structure preferably includes a limiting convex rib arranged on the outer side wall of the limiting column 33, and the water spraying head 31 is provided with a insertion hole in the middle, the limiting column 33 is inserted into the insertion hole from back to front, and the inner side wall of the insertion hole is provided with a limiting slot, and the limiting convex rib can be inserted into the limiting slot and slide forward and backward.

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

[0068] For matters not covered, please refer to the patent CN220759627U previously applied by the applicant, which will not be repeated here.
