Abstract
Description
Technical Field
[0001] This invention relates to the field of water gun technology, and more particularly to a water gun. Background Technology
[0002] Water guns usually have a mechanism to adjust the water spray. Bullet-shaped water guns are a common type of water gun. Figure 9 The image shows the structure of a standard bullet-shaped water gun nozzle. Standard bullet-shaped water guns typically use a threaded connection structure to adjust the water spray. That is, the nozzle usually includes an end sleeve, an adjusting sleeve, and a core. The adjusting sleeve is fixed to the end sleeve, and a threaded connection is provided between the core and the adjusting sleeve. Figure 9 The threaded structure shown in area A allows for water spray adjustment by twisting the adjusting sleeve, causing the tube core to expand and contract within the end sleeve. However, this type of bullet-shaped water gun has the following problems:
[0003] 1) Assembly difficulties: If the assembly precision is not well controlled during product assembly, and the screw threads are not aligned before being pressed, the screw threads can easily be damaged.
[0004] 2) such as Figure 9 As shown in area A, when the adjusting sleeve is turned forward to the maximum distance, the two threads separate. However, when the two threads are turned back after they separate, the threads are difficult to re-engage. Therefore, it is difficult to adjust the water splash after the threads separate.
[0005] 3) Conventional bullet-shaped water guns use ordinary threads, which require turning the knob many times to adjust the water spray, resulting in low adjustment efficiency.
[0006] It is not easy to disassemble and assemble.
[0007] This invention was made based on this situation. Summary of the Invention
[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a water gun that is easy to adjust the water spray and easy to assemble and disassemble.
[0009] This invention is achieved through the following technical solution:
[0010] To solve the above-mentioned technical problems, the present invention provides a water gun, including a water gun body and a water gun head detachably connected to the front end of the water gun body;
[0011] The water gun head includes an end sleeve and a tube core that can move back and forth therein. The end sleeve is provided with a water spray chamber and a water spray nozzle communicating with the water spray chamber. The rear end of the tube core is provided with a water inlet, and the front end of the tube core is provided with a water outlet communicating with the water spray chamber and a water plug extending to the water spray nozzle.
[0012] An adjustment structure is provided between the tube core and the end sleeve, which can drive the tube core to move back and forth to adjust the water splash. The adjustment structure includes an adjustment sleeve detachably connected to the end sleeve and a limiting sleeve detachably connected between the end sleeve and the adjustment sleeve. The limiting sleeve is provided with a front spiral platform, and the inner wall of the adjustment sleeve is provided with a rear spiral platform. The front spiral platform and the rear spiral platform form a spiral groove. The outer wall of the tube core is provided with a protrusion, and the protrusion is inserted into the spiral groove. When the end sleeve, the adjustment sleeve and the limiting sleeve are driven to rotate together, the protrusion can move along the spiral groove, thereby causing the tube core to move back and forth.
[0013] To further solve the technical problem to be solved by the present invention, the present invention provides a water gun in which the limiting sleeve is inserted into the adjusting sleeve from front to back and a circumferential limiting structure for limiting the rotation of the limiting sleeve and a rear limiting structure for limiting the backward movement of the limiting sleeve are provided between the two. The rear end of the end sleeve is inserted into the front end of the adjusting sleeve from front to back and a detachable connection structure is provided between the two. The rear end of the end sleeve abuts against the front end of the adjusting sleeve to block the limiting sleeve from the front.
[0014] To further solve the technical problem to be solved by the present invention, the present invention provides a water gun in which the circumferential limiting structure includes a positioning groove disposed on the inner side wall of the adjusting sleeve along the front-back direction, and a positioning protrusion disposed on the limiting sleeve and extending rearward and capable of being inserted into the positioning groove.
[0015] To further solve the technical problem to be solved by the present invention, the present invention provides a water gun in which the rear limiting structure includes a rear limiting surface provided on the inner side wall of the adjusting sleeve and a front limiting surface provided on the limiting sleeve and capable of abutting against the rear limiting surface.
[0016] To further address the technical problem to be solved by the present invention, the present invention provides a water gun in which the detachable connection structure includes an internal thread on the inner side wall of the front end of the adjusting sleeve and an external thread on the outer side wall of the rear end of the end sleeve that can mate with the internal thread.
[0017] To further address the technical problem addressed by this invention, a water gun is provided in which a protective sleeve is provided outside the adjusting sleeve, and the protective sleeve is detachably connected to the adjusting sleeve.
[0018] To further solve the technical problem to be solved by the present invention, the present invention provides a water gun in which the inner wall of the protective sleeve is provided with a plurality of anti-rotation grooves and the outer wall of the adjusting sleeve is provided with a plurality of anti-rotation protrusions that can be inserted into the corresponding anti-rotation grooves.
[0019] To further address the technical problems addressed by this invention, the present invention provides a water gun in which the outer wall of the protective sleeve is provided with anti-slip texture.
[0020] To further address the technical problems to be solved by this invention, a water gun provided by this invention includes a first sealing ring between the adjusting sleeve and the end sleeve.
[0021] To further address the technical problems to be solved by this invention, a water gun provided by this invention includes a second sealing ring between the limiting sleeve and the core.
[0022] Compared with the prior art, the present invention has the following advantages:
[0023] 1. In this invention, the spiral groove formed by the front spiral stage and the rear spiral stage is closed, and the protrusion is confined in the spiral groove. Therefore, the end sleeve and the adjusting sleeve will not come out of the tube core due to excessive twisting, nor will they be blown out of the tube core due to water pressure impact.
[0024] 2. In this invention, the spiral groove formed by the front and rear spiral stages is closed, and the protrusion is confined in the spiral groove. No matter how it is twisted, the protrusion is always in the spiral groove. Therefore, the twisting is always smooth and there is no problem of difficulty in twisting back, which makes the adjustment always smooth and convenient.
[0025] 3. The assembly of this invention is relatively convenient and will not cause damage or broken teeth. Since the front and rear spiral stages are independent and assembled together, the assembly process involves first placing the core into the limiting sleeve, then inserting the limiting sleeve into the adjusting sleeve, and finally inserting the end sleeve to block the limiting sleeve. Therefore, the installation process is simple and convenient, facilitating automated assembly and minimizing damage to components.
[0026] 4. All components of this invention are detachable without damaging them, making it convenient for disassembly, maintenance, and replacement.
[0027] 5. In this invention, the number of spiral grooves formed by the front and rear spiral stages is relatively small. Compared with ordinary threads, the fewer spiral grooves formed by the front and rear spiral stages result in higher adjustment efficiency. That is, for the same twisting stroke, this invention requires fewer twisting turns. Attached Figure Description

[0038] 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 with reference to the accompanying drawings and specific embodiments.
[0039] like Figures 1 to 8 The water gun shown includes a water gun body 8 and a water gun head detachably connected to the front end of the water gun body 8. The water gun head includes an end sleeve 1 and a core 2 that can move back and forth within it. The end sleeve 1 has a spray chamber 11 and a spray nozzle 12 communicating with the spray chamber 11. The rear end of the core 2 has an inlet 21, and the front end of the core 2 has an outlet 22 communicating with the spray chamber 11, and a plug 23 extending towards the spray nozzle 12. Water flows into the core 2 from the inlet 21, flows into the spray chamber 11 from the outlet 22, and then sprays outward from the gap between the plug 23 and the spray nozzle 12. The gap between the plug 23 and the spray nozzle 12 is related to the size of the water spray. When the plug 23 moves forward, the gap between the plug 23 and the spray nozzle 12 decreases, and the water spray becomes smaller; conversely, the water spray becomes larger.
[0040] like Figures 1-8As shown, an adjustment structure is provided between the tube core 2 and the end sleeve 1, which can drive the tube core 2 to move back and forth to adjust the water spray. The adjustment structure includes an adjustment sleeve 3 detachably connected to the end sleeve 1 and a limiting sleeve 4 detachably connected between the end sleeve 1 and the adjustment sleeve 3. The limiting sleeve 4 is provided with a front spiral platform 41, and the inner wall of the adjustment sleeve 3 is provided with a rear spiral platform 31. The front spiral platform 41 and the rear spiral platform 31 form a spiral groove. The outer wall of the tube core 2 is provided with a protrusion 24, and the protrusion 24 is inserted into the spiral groove. When the end sleeve 1, the adjustment sleeve 3 and the limiting sleeve 4 are rotated together, the protrusion 24 can move along the spiral groove, thereby causing the tube core 2 to move back and forth. That is, when the end sleeve 1 and the adjustment sleeve 3 (which are relatively fixed) are rotated, the protrusion 24 moves along the spiral groove, thereby causing the tube core 2 to move back and forth within the end sleeve 1 and the adjustment sleeve 3. In other words, the water plug 23 moves closer to and further away from the spray nozzle 12, thereby achieving the adjustment of the water spray.
[0041] In this invention, the spiral groove formed by the front spiral stage 41 and the rear spiral stage 31 is closed, and the protrusion 24 is confined in the spiral groove. Therefore, the end sleeve 1 and the adjusting sleeve 3 will not come off the tube core 2 due to excessive twisting, nor will they be blown out of the tube core 2 due to water pressure impact.
[0042] In this invention, the spiral groove formed by the front spiral stage 41 and the rear spiral stage 31 is closed, and the protrusion 24 is confined in the spiral groove. No matter how it is twisted, the protrusion 24 is always in the spiral groove. Therefore, the twisting is always relatively smooth and there is no problem of difficulty in twisting back, which makes the adjustment always smooth and convenient.
[0043] The assembly of this invention is relatively convenient and will not cause damage or broken teeth. Since the front spiral stage 41 and the rear spiral stage 31 are independent of each other and are assembled, the assembly process involves first placing the core 2 into the limiting sleeve 4, then inserting the limiting sleeve 4 into the adjusting sleeve 3, and finally inserting the end sleeve 1 to block the limiting sleeve 4. Therefore, the installation process is simple and convenient, facilitating automated assembly and minimizing the risk of damaging components.
[0044] All components of this invention are detachable, such as end sleeve 1, core 2, adjusting sleeve 3, limiting sleeve 4, and protective sleeve 5. Disassembly will not damage the components, making it convenient for disassembly, maintenance, and replacement of components.
[0045] In this invention, the spiral groove formed by the front spiral platform 41 and the rear spiral platform 31 has fewer turns, preferably less than three turns. Compared to ordinary threads, the spiral groove formed by the front spiral platform 41 and the rear spiral platform 31 with fewer turns has higher adjustment efficiency; that is, for the same twisting stroke, this invention requires fewer twisting turns.
[0046] More specifically, the limiting sleeve 4 is inserted into the adjusting sleeve 3 from front to back, and a circumferential limiting structure for limiting the rotation of the limiting sleeve 4 and a rear limiting structure for limiting the backward movement of the limiting sleeve 4 are provided between the two. The rear end of the end sleeve 1 is inserted into the front end of the adjusting sleeve 3 from front to back, and a detachable connection structure is provided between the two. The rear end of the end sleeve 1 abuts against the front end of the adjusting sleeve 3, thereby blocking the limiting sleeve 4 from the front.
[0047] More specifically, the circumferential limiting structure includes a positioning groove 32 disposed on the inner sidewall of the adjusting sleeve 3 along the front-back direction, and a positioning protrusion 42 disposed on the limiting sleeve 4 and extending rearward and capable of being inserted into the positioning groove 32.
[0048] More specifically, such as Figure 4 , Figure 5 As shown, the rear limiting structure includes a rear limiting surface 33 provided on the inner side wall of the adjusting sleeve 3, and a front limiting surface 43 provided on the limiting sleeve 4 and capable of abutting against the rear limiting surface 33.
[0049] More specifically, the detachable connection structure includes an internal thread 34 on the inner sidewall of the front end of the adjusting sleeve 3, and an external thread 13 on the outer sidewall of the rear end of the end sleeve 1 that can mate with the internal thread 34. That is, the adjusting sleeve 3 is threadedly connected to the end sleeve 1.
[0050] More specifically, the adjusting sleeve 3 is covered with a protective sleeve 5 to protect the adjusting sleeve 3 and to make it easier to rotate the adjusting sleeve 3. The protective sleeve 5 is detachably connected to the adjusting sleeve 3.
[0051] Furthermore, such as Figure 7 , Figure 4 As shown, the inner wall of the protective sleeve 5 is provided with several anti-rotation grooves 51, and the outer wall of the adjusting sleeve 3 is provided with several anti-rotation protrusions 35 that can be inserted into the corresponding anti-rotation grooves 51.
[0052] More specifically, the outer side wall of the protective sleeve 5 is provided with anti-slip texture 52, which makes it easy to hold and rotate the protective sleeve 5 by hand.
[0053] More specifically, a first sealing ring 6 is provided between the adjusting sleeve 3 and the end sleeve 1, and a second sealing ring 7 is provided between the limiting sleeve 4 and the core 2. Both the first sealing ring 6 and the second sealing ring 7 are preferably rubber rings or silicone rings, which seal and prevent water leakage during operation.
[0054] This invention is easy to assemble and disassemble. The main steps during installation are as follows:
[0055] 1) First, put the adjusting sleeve 3 on the tube core 2. After it is in place, rotate the adjusting sleeve 3 so that its positioning groove 32 is misaligned with the protrusion 24 on the tube core 2.
[0056] 2) Insert the limiting sleeve 4 into the adjusting sleeve 3, wherein the positioning protrusion 42 on the limiting sleeve 4 is inserted into the groove 32 on the adjusting sleeve 3, and the front limiting surface 43 on the limiting sleeve 4 abuts against the rear limiting surface 33 on the adjusting sleeve 3. At this time, after the two parts are combined, a spiral-shaped spiral track groove is formed inside. The spiral track groove is surrounded by the front spiral platform 41 and the rear spiral platform 31, and the protrusion 24 is located exactly in the spiral track groove.
[0057] 3) Put the protective cover 5 onto the adjusting sleeve 3;
[0058] 4) Install end sleeve 1, second sealing ring 7 and first sealing ring 6. When installing end sleeve 1, the external thread 13 on end sleeve 1 and the internal thread 34 on adjusting sleeve 3 cooperate with each other, and the rear end face of end sleeve 1 abuts against the front end face of adjusting sleeve 3.
[0059] When you need to adjust the water spray, simply rotate the protective sleeve 5 forward or backward.
[0060] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
