Description

Technical Field

[0001] This utility model relates to the field of water gun technology, specifically a filter structure for water guns. Background Technology

[0002] A water gun is a machine that sprays water high or far to clean surfaces. Because water carries impurities, it's usually necessary to filter the water before use to prevent damage. However, existing water gun filtration systems still have certain shortcomings, such as:

[0003] The water gun filtration device with application number CN202222117404.1 uses a vertical water flow for filtration. This method results in high water pressure and excessive flow rate when the water enters, leading to unsatisfactory filtration. Fine particles and impurities can easily break through the filter layer and enter the water gun with the water flow, thus affecting the normal use of the water gun. In view of this, it is of great practical significance to develop a water gun pre-filtration structure that can effectively solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter structure for a water gun, comprising a filter, wherein a water inlet pipe is fixedly connected to the left side of the filter, and a water outlet pipe is fixedly connected to the top of the filter.

[0006] The bottom of the water inlet pipe is fixedly connected to a connecting pipe, and the connecting pipe is connected to a connecting pipe through a disassembly and assembly mechanism, and the bottom of the connecting pipe is fixedly connected to an external water supply pipe.

[0007] A sedimentation tube is threadedly connected to the inner right side of the filter. An annular filter screen is installed inside the filter, with the left end face of the annular filter screen abutting against the water inlet pipe and the right end face of the annular filter screen abutting against the sedimentation tube.

[0008] The above technical solution facilitates effective filtration of water flow.

[0009] As a preferred embodiment of this utility model, the filter is set at an angle of 100° with the water outlet pipe.

[0010] The above technical solution facilitates the discharge of water at a non-vertical angle, thereby reducing water pressure and slowing down the flow rate.

[0011] As a preferred embodiment of this utility model, the top of the water inlet pipe is a bend with an included angle of 100°.

[0012] By adopting the above technical solution, it is easy to ensure that the water flows in at a non-vertical angle, thereby reducing water pressure, slowing down the flow rate, extending the filtration time, and improving the filtration effect.

[0013] As a preferred embodiment of this utility model, a threaded pipe is fixedly installed on the top of the water outlet pipe, and the threaded pipe is threadedly connected to an external water gun.

[0014] The above technical solution facilitates quick assembly and disassembly with external water guns.

[0015] As a preferred embodiment of this utility model, a sealing ring is provided on the inner bottom surface of the connecting pipe, and the connecting pipe is sleeved on the outside of the connecting pipe, and the inner diameter of the connecting pipe matches the outer diameter of the connecting pipe.

[0016] The above technical solution facilitates improved sealing performance.

[0017] As a preferred embodiment of this utility model, the disassembly and assembly mechanism includes a movable sleeve, which is fitted onto the outer wall of the connecting pipe and slidably connected to the connecting pipe. Push blocks are fixedly installed on the left and right inner walls of the movable sleeve, and the inner side of the push block movably abuts against a limiting rod. The limiting rod slidably passes through a through hole opened in the side wall of the connecting pipe, and the inner end of the limiting rod is movably inserted into a limiting groove, which is opened on the outer wall of the connecting pipe. A spring is fixedly installed on the bottom surface of the push block, and a fixing block is fixedly installed on the bottom end of the spring, which is fixedly installed on the outer wall of the connecting pipe.

[0018] The above technical solution facilitates quick assembly and disassembly with external water supply equipment.

[0019] As a preferred embodiment of this utility model, the top surface of the pusher is inclined, and the inclined surface is oriented towards the connecting pipe.

[0020] By adopting the above technical solution, the pusher can stably and effectively push the limit rod during the movement process.

[0021] As a preferred embodiment of this utility model, both the inner and outer ends of the limiting rod are hemispherical structures.

[0022] The above technical solution facilitates the smooth movement of the limit lever.

[0023] As a preferred embodiment of this utility model, sliding rods are fixedly installed on both the upper and lower surfaces of the limiting rod, and the sliding rods are slidably connected to the sliding grooves opened on both sides of the through hole.

[0024] The above technical solution facilitates the stability of the limit rod.

[0025] As a preferred embodiment of this utility model, the limiting groove is annular on the outer wall of the connecting pipe, and the limiting groove matches the limiting rod.

[0026] The above technical solution facilitates the engagement of the limiting rod and the limiting groove from any angle, improving operational convenience.

[0027] Compared with the prior art, the beneficial effects of this utility model are: the filter structure for water guns changes the inlet and outlet angle of the water flow through a unique structural design, avoiding vertical water flow in and out. When the water flows in, the water pressure decreases and the flow rate slows down, allowing more time for filtration in the filter, thus improving the filtration quality. At the same time, the reduced water flow reduces the impact force on the filter screen, lowering the risk of filter screen damage and further ensuring the effectiveness of filtration.

[0028] 1. The angled design of the inlet and outlet pipes prevents water from entering at an angle, reduces water pressure, slows down water flow, and improves filtration. This makes it less likely for fine particles and impurities to be flushed into the water gun, ensuring the effectiveness of the water gun.

[0029] 2. The design of the disassembly structure facilitates the disassembly and assembly with external water supply equipment, while the threaded pipe facilitates the disassembly and assembly with external water guns, improving the convenience and flexibility of use.

[0030] 3. Water flows through a ring-shaped filter screen for filtration. The filtered impurities are collected in the sedimentation tube. The detachable assembly design of the sedimentation tube and the filter makes it easy to clean the filtered fine particles and impurities. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figure 1 - Figure 7 The present invention provides a filter structure for a water gun, comprising a filter 1, an inlet pipe 2 fixedly connected to the left side of the filter 1, the top of the inlet pipe 2 being a bend with an angle of 100°, and an outlet pipe 3 fixedly connected to the top of the filter 1, the filter 1 and the outlet pipe 3 forming an angle of 100°, a connecting pipe 4 fixedly connected to the bottom of the inlet pipe 2, and a connecting pipe 6 connected to the connecting pipe 4 via a disassembly and assembly mechanism, and the bottom of the connecting pipe 6 being fixedly connected to an external water supply pipe.

[0041] A sedimentation tube 7 is threadedly connected to the inner right side of the filter 1. An annular filter screen 8 is installed inside the filter 1, and the left end face of the annular filter screen 8 abuts against the water inlet pipe 2, while the right end face of the annular filter screen 8 abuts against the sedimentation tube 7.

[0042] A threaded pipe 5 is fixedly installed on the top of the water outlet pipe 3, and the threaded pipe 5 is threadedly connected to the external water gun.

[0043] A sealing ring 9 is provided on the inner bottom surface of the connector 6, and the connector 6 is sleeved on the outside of the connecting pipe 4, and the inner diameter of the connector 6 matches the outer diameter of the connecting pipe 4.

[0044] The disassembly and assembly mechanism includes a movable sleeve 10, which is fitted onto the outer wall of the connecting pipe 6 and slidably connected to the connecting pipe 6. Push blocks 11 are fixedly installed on the left and right inner walls of the movable sleeve 10. The top surface of the push block 11 is inclined, and the inclined direction faces the connecting pipe 6. The inner side of the push block 11 movably abuts against a limiting rod 12. The inner and outer ends of the limiting rod 12 are hemispherical structures. The limiting rod 12 slides through the through hole 13 opened in the side wall of the connecting pipe 4, and the inner end of the limiting rod 12 is movably inserted into the limiting groove 14. The limiting groove 14 is opened on the outer wall of the connecting pipe 4 and is annular in design. The limiting groove 14 matches the limiting rod 12. A spring 15 is fixedly installed on the bottom surface of the push block 11, and a fixing block 16 is fixedly installed on the bottom end of the spring 15. The fixing block 16 is fixedly installed on the outer wall of the connecting pipe 6.

[0045] The upper and lower surfaces of the limiting rod 12 are fixedly equipped with sliding rods 17, and the sliding rods 17 are slidably connected to the sliding grooves 18 opened on both sides of the through hole 13.

[0046] Working principle: Water flows into the connecting pipe 6 from the external water supply pipe. Since the connecting pipe 6 and the connecting pipe 4 are tightly connected and well sealed by the sealing ring 9, the water will not leak. Then, the water enters the inlet pipe 2 through the connecting pipe 4. The 100° bend design at the top of the inlet pipe 2 changes the direction of water flow, reduces the water flow speed and water pressure, and reduces the impact on the subsequent filtration structure. The water flowing into the filter 1 will be filtered by the annular filter screen 8. The left end face of the annular filter screen 8 abuts against the inlet pipe 2, and the right end face abuts against the sedimentation pipe 7. This makes the water flow in the filter 1 only able to flow to the outlet pipe 3 through the annular filter screen 8. During this process, impurities in the water are intercepted by the annular filter screen 8, thereby achieving the filtration of the water flow. The filtered water flows out from the outlet pipe 3 and enters the external water gun through the threaded pipe 5.

[0047] During the filtration process, impurities will settle into the sedimentation tube 7 under the action of gravity. Since the sedimentation tube 7 is threaded to the inner wall of the right side of the filter 1, when it is necessary to clean the impurities, the sedimentation tube 7 can be rotated to remove it from the filter 1, pour out the settled impurities, and then reinstall the sedimentation tube 7 back into the filter 1 for continued use.

[0048] When disassembling from the external water supply pipe, push the movable sleeve 10 downward to drive the push block 11 to move downward and compress the spring 15. After the push block 11 moves downward and separates from the limit rod 12, the connecting pipe 4 can be moved upward, so that the push limit rod 12 moves outward and moves out of the limit groove 14, thereby realizing the disassembly of the connecting pipe 4 and the connecting pipe 6.

[0049] During installation, the connecting pipe 4 is inserted into the connecting pipe 6, and the movable sleeve 10 is released. Under the release action of the spring 15, the push block 11 is pushed to move downward, causing the movable sleeve 10 to move upward synchronously until the inner bottom surface of the movable sleeve 10 touches the fixed block 16. When the push block 11 moves upward, it will push the limiting rod 12 to move inward, so that the limiting rod 12 is locked into the limiting groove 14, thus realizing the installation of the connecting pipe 4 and the connecting pipe 6.
