Description

Technical Field

[0001] This utility model relates to the field of car wash brush technology, specifically a water spray type car wash brush. Background Technology

[0002] Car wash brushes play a crucial role in the car washing process. Their main function is to work with car wash liquid to remove dirt from the car's surface, allowing the dirt to be removed from the car body through the use of the car wash brush, thus making the car body clean.

[0003] Existing car wash brushes require being fully soaked in car wash liquid before being used to clean the car's surface. After a period of use, the brushes need to be re-soaked in car wash liquid, which leads to frequent re-soaking and inconvenience for users.

[0004] To address the aforementioned shortcomings, a water-spraying car wash brush with publication number CN221986409U is disclosed. This brush connects a hollow handle to a high-pressure water pipe, allowing water to be sprayed onto the bristles through nozzles for car washing. When the bristles are damaged, the bristle fixing plate can be removed and replaced with a new one for continued use. Compared to existing technologies, the cost of the bristle fixing plate and the bristles is far lower than the overall cost of ordinary car wash brushes or water-spraying car wash brushes, thereby reducing the usage cost of water-spraying car wash brushes.

[0005] In actual use, although the device can spray water by connecting a high-pressure water hose, it requires connecting the high-pressure water hose to the hollow handle and holding the handle to clean. The high-pressure water hose restricts its use, requiring the hose to be dragged, which is inconvenient.

[0006] Therefore, we proposed a water-spraying car wash brush that can effectively solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide a water spray type car wash brush to solve the problem mentioned in the background art that the current market requires connecting a high-pressure water hose to a hollow handle, and then holding the hollow handle to achieve the purpose of cleaning. However, the high-pressure water hose will restrict the use and require dragging the high-pressure water hose, which will make it inconvenient to use.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a water-spraying car wash brush, including a handle, wherein bristles are attached to the right side of the handle;

[0009] The left end of the handle is fixed with a liquid storage tube, and a push rod is slidably connected inside the liquid storage tube. The top of the liquid storage tube is connected to a water spray pipe, and the top of the water spray pipe extends into the inside of the handle and penetrates the bristles.

[0010] The handle is internally slidably connected to a locking block, the inner end of which extends into the slot to form a locking connection. The slot is located at the left end of the bristles. The outer end of the locking block is connected to a spring, and the outer end of the spring is connected to the inside of the handle. The locking block self-positions the bristles.

[0011] Furthermore, the top of the push rod is made of rubber, and two sets of sealing rings are nested on the top of the push rod, with the outer walls of the two sets of sealing rings fitting against the inner wall of the liquid storage tube.

[0012] Furthermore, the right side of the inner end of the card block is arc-shaped, and the arc-shaped position of the card block is fitted to the outer wall of the card slot.

[0013] Furthermore, the outer end of the card block is connected to a pull rope, and the outer end of the pull rope extends out of the handle through a spring to form a sliding structure, and the outer end of the pull rope is fitted against the outer wall of the handle.

[0014] Furthermore, a roller is fitted to the bend of the pull rope, and the roller is connected to the inside of the handle via a bearing.

[0015] Furthermore, the top of the water spray pipe is made of rubber material, and the position of the water spray pipe protrudes slightly from the inside of the handle, while the top of the water spray pipe is hidden inside the bristles.

[0016] Furthermore, a grip is slidably connected to the bottom of the handle, and a slider is slidably connected to the top of the grip. The outer end of the slider extends into the interior of the slide groove to form a locking connection. The slide groove is evenly spaced inside the handle. A limiting spring is connected to the inner end of the slider, and the inner end of the limiting spring is connected to the interior of the grip.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Example 1: This utility model solves the problem that existing methods require connecting a high-pressure water hose to a hollow handle, then holding the handle to clean. However, the high-pressure water hose restricts its use, requiring dragging and causing inconvenience. The use of the liquid storage tube 3 improves ease of use. The following is disclosed:

[0033] The right side of the handle 1 is fitted with bristles 2; the left end of the handle 1 is fixed with a liquid storage tube 3, and a push rod 4 is slidably connected inside the liquid storage tube 3. The top of the liquid storage tube 3 is connected to a water spray pipe 5. The top of the water spray pipe 5 extends into the interior of the handle 1 and passes through the bristles 2. The top of the push rod 4 is made of rubber, and two sets of sealing rings 6 are nested in the top of the push rod 4. The outer walls of the two sets of sealing rings 6 are fitted with the inner wall of the liquid storage tube 3. The top of the water spray pipe 5 is made of rubber material, and the position of the water spray pipe 5 protrudes slightly from the interior of the handle 1. The position of the top of the water spray pipe 5 is hidden inside the bristles 2.

[0034] refer to Figures 1 to 4 When a car wash is needed, pull the push rod 4 to disengage it from the inside of the liquid reservoir 3. Then, invert the handle 1 so that the liquid reservoir 3 faces upwards. Pour car wash liquid into the liquid reservoir 3, and then insert the push rod 4 back into the liquid reservoir 3. This causes the push rod 4 to move and drive the sealing ring 6 into the inside of the liquid reservoir 3. The sealing ring 6 seals the push rod 4 and the liquid reservoir 3, preventing water from overflowing. Push the push rod 4 to move it further into the liquid reservoir 3, causing it to squeeze the liquid in the liquid reservoir 3 and deliver it to the water spray pipe 5. This allows the water spray pipe 5 to spray water. At this time, the brush bristles 2 will be wetted by the car wash liquid due to contact with the car body. Finally, operate the handle 1 to drive the brush bristles 2 to clean the car body, thus achieving the purpose of convenient use.

[0035] Example 2: This utility model solves the problem that existing brushes need to be replaced entirely after wear, thus increasing the cost of use. By using a pull rope 10, the brush bristles 2 can be replaced, thereby reducing the cost of use. The following is disclosed:

[0036] The outer end of the locking block 7 is connected to a pull rope 10, and the outer end of the pull rope 10 extends out of the handle 1 through a spring 9 to form a sliding structure. The outer end of the pull rope 10 is fitted against the outer wall of the handle 1. A roller 11 is fitted against the bend of the pull rope 10, and the roller 11 is connected to the inside of the handle 1 through a bearing. The inner end of the locking block 7 extends into the inside of the locking groove 8 to form a locking connection, and the locking groove 8 is opened at the left end of the bristles 2.

[0037] refer to Figures 1 to 3 , Figure 5 and Figure 6 After prolonged use, the bristles 2 will wear down due to friction with the vehicle body. Pulling the pull cord 10 will cause the pull cord 10 to move, which in turn moves the roller 11 to drive the locking block 7. This causes the locking block 7 to move into the handle 1, disengaging from the locking slot 8. The movement of the locking block 7 will also compress the spring 9, pulling the bristles 2 and allowing them to disengage from the handle 1. This makes the bristles 2 replaceable, thus reducing the cost of use.

[0038] Example 3: This utility model solves the problem of existing brushes not being detachable. The use of the locking block 7 allows for quick assembly and disassembly of the brush bristles 2. The following is disclosed:

[0039] The outer end of the locking block 7 is connected to a spring 9, and the outer end of the spring 9 is connected to the inside of the handle 1 to form a limiting structure. The inside of the handle 1 is slidably connected to the locking block 7, and the right side of the inner end of the locking block 7 is arc-shaped. The bottom of the handle 1 is slidably connected to the grip 12, and the top of the grip 12 is slidably connected to the slider 13. The outer end of the slider 13 extends into the inside of the slide groove 14 to form a locking connection. The slide groove 14 is evenly spaced inside the handle 1. The inner end of the slider 13 is connected to a limiting spring 15, and the inner end of the limiting spring 15 is connected to the inside of the grip 12. The inner end of the slider 13 is connected to a pull ring 16, and the bottom of the pull ring 16 extends out of the bottom of the grip 12 to form a sliding structure.

[0040] refer to Figures 1 to 3 , Figures 5 to 7By inserting the brush bristles 2 into the handle 1, the movement of the brush bristles 2 compresses the locking block 7, causing the locking block 7 to move inward into the handle 1. This movement of the locking block 7 compresses the spring 9. After the brush bristles 2 reach their position, the force of the spring 9 pushes the locking block 7 into the slot 8 to engage, thus allowing the brush bristles 2 to be stably connected to the handle 1, achieving quick installation. When cleaning higher positions, pulling the pull ring 16 causes the pull ring 16 to move, which in turn moves the slider 13. This causes the slider 13 to disengage from the slot 14, and the movement of the slider 13 compresses the limiting spring 15, causing the limiting spring 15 to be compressed. This allows the grip 12 to slide inside the handle 1. After reaching its position, the force of the limiting spring 15 pushes the slider 13 into the slot 14 to engage, thus allowing the height of the handle 1 to be adjusted according to different vehicles, thereby improving adaptability.

[0041] When using this type of water spray car wash brush, first, refer to... Figures 1 to 4 When a car wash is needed, pull the push rod 4 to disengage it from the inside of the liquid reservoir 3. Then, invert the handle 1 so that the liquid reservoir 3 is facing upwards. Pour car wash liquid into the liquid reservoir 3, and then insert the push rod 4 back into the liquid reservoir 3. Through the use of the sealing ring 6, the push rod 4 and the liquid reservoir 3 are sealed together. Then, push the push rod 4 to move it into the liquid reservoir 3, so that the water spray pipe 5 can spray water. At this time, the brush bristles 2 will be wetted by the car wash liquid due to contact with the car body. Then, operate the handle 1 so that the handle 1 can drive the brush bristles 2 to clean the car body, thus achieving the purpose of convenient use.

[0042] refer to Figures 1 to 3 , Figure 5 and Figure 6 After long-term use, the bristles 2 will wear down due to friction with the vehicle body. By pulling the pull rope 10, the locking block 7 will move into the handle 1, and the locking block 7 will disengage from the locking slot 8. Then, by pulling the bristles 2, the bristles 2 can be disengaged from the handle 1, so that the bristles 2 can be replaced, thereby reducing the cost of use.

[0043] refer to Figures 1 to 3 , Figures 5 to 7By inserting the brush bristles 2 into the handle 1, the movement of the brush bristles 2 will squeeze the locking block 7, which in turn will cause the locking block 7 to move into the handle 1. After the brush bristles 2 have moved to the position, the force of the spring 9 will push the locking block 7 into the slot 8 to form a lock, thereby achieving the purpose of quick installation. When cleaning higher positions, by pulling the pull ring 16, the movement of the pull ring 16 will drive the slider 13 to move, and the movement of the slider 13 will squeeze the limiting spring 15, thereby compressing the limiting spring 15. After moving to the position, the force of the limiting spring 15 will push the slider 13 into the slide groove 14 to form a lock, thereby improving adaptability.
