Description

Technical Field

[0001] This utility model relates to the field of cleaning brush technology, and in particular to a cleaning brush that allows for continuous water flow. Background Technology

[0002] A cleaning brush is a commonly used tool, typically used to remove dust and other impurities from surfaces. To facilitate stain removal, users usually operate the brush with one hand while using another tool (such as a hose or ladle) to wet the area to be cleaned with the other. Cleaning brushes that can continuously supply water are now available on the market. These brushes can be connected to an external water pipe, allowing users to simultaneously perform both rinsing and brushing with one hand.

[0003] In reality, areas with thick layers of dust require a strong water flow to rinse, while areas with lighter dust only need slight dampening. However, conventional water-cooled cleaning brushes are usually directly connected to an external water pipe, allowing control only on whether water flows into the brush, not on the flow rate. Existing continuously flowing water cleaning brushes cannot effectively adjust the water volume according to the needs of different cleaning scenarios, making them inconvenient to use and resulting in water waste. Utility Model Content

[0004] To overcome the technical problem that existing cleaning brushes with continuous water flow cannot control the water flow rate, this utility model provides a cleaning brush with continuous water flow.

[0005] To achieve the above objectives, this utility model proposes a continuously flowing water cleaning brush, comprising a brush handle and a brush head, with one end of the brush handle fixedly connected to the brush head. The brush handle has an inner groove, and the brush head has a bottom compartment. The inner groove is distributed along the length of the brush handle and communicates with the bottom compartment. A flow control component is located at the end of the inner groove furthest from the brush head. The flow control component is movably connected along the length of the brush handle, and the end of the flow control component furthest from the brush handle is connected to an external water pipe via a flexible hose.

[0006] Furthermore, the flow control assembly includes a pipe connector and a moving tube. One end of the pipe connector is connected to the moving tube, and the other end is connected to the flexible hose. The end of the moving tube near the brush rod is provided with an internally threaded cylinder, and the brush rod is provided with an externally threaded end that mates with the internally threaded cylinder.

[0007] Furthermore, the moving tube is equipped with a through plate, which has multiple through holes and an integrated cone. The brush rod has an opening at the position corresponding to the cone.

[0008] Furthermore, a positioning groove is provided on the end face of the inlet near the moving tube, and a retaining sleeve is provided on the positioning groove. The retaining sleeve is made of a high-polymer elastic material and has a tapered hole that matches the cone.

[0009] Furthermore, the end face of the internally threaded cylinder near the brush rod is provided with a side edge. A first limiting ring is provided at the position of the brush rod corresponding to the side edge, and the side edge is located between the externally threaded end and the first limiting ring; a U-shaped sealing ring is provided on the side edge.

[0010] Furthermore, the moving pipe has an integrated step on the side near the pipe joint, and a filter screen is installed on the side of the step near the pipe joint. The filter screen is arched and protrudes outward towards the pipe joint.

[0011] Furthermore, the brush head includes a base plate, which is concave in shape. A first reinforcing rib is provided on the concave surface of the base plate, and multiple evenly spaced second reinforcing ribs are provided on the edges of the base plate.

[0012] Furthermore, a water inlet pipe is provided on the bottom plate, with one end connected to the inner tank and the other end connected to the bottom compartment. A valve is provided on the water inlet pipe. A brush block is provided on the side of the bottom plate away from the water inlet pipe, and multiple bottom pipes are provided on the bottom surface of the bottom compartment, all of which are inserted into the brush block.

[0013] Furthermore, the diameter of the bottom tube gradually decreases along the direction towards the brush block, and multiple bottom tubes are connected to the bottom chamber. Multiple evenly spaced side holes are provided in the circumference of each bottom tube.

[0014] Furthermore, the bottom hopper is equipped with a material pipe that connects to the outside world, and the material pipe is equipped with a detachable end cap.

[0015] The beneficial effects of this invention are as follows: the brush handle continuously delivers water to the brush head through the inner groove, making it convenient for users to clean while simultaneously applying water, thus improving cleaning efficiency. The flow rate of the inner groove is controlled by adjusting the position of the flow control component along the length of the brush handle, allowing users to adjust the water output of the cleaning brush according to different cleaning scenarios, ensuring both cleaning efficiency and water conservation.

[0027] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0028] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0029] like Figure 1-8 As shown, this utility model proposes a continuously water-flowing cleaning brush, including a brush handle 1 and a brush head 3. One end of the brush handle 1 is fixedly connected to the brush head 3. The brush handle 1 has an inner groove 11, and the brush head 3 has a bottom chamber 34. The inner groove 11 is distributed along the length of the brush handle 1 and communicates with the bottom chamber 34. A flow control component 2 is provided at the end of the inner groove 11 away from the brush head 3. The flow control component 2 is movably connected along the length of the brush handle 1, and the end of the flow control component 2 away from the brush handle 1 is connected to an external water pipe through a hose 4. Water flows along the hose 4 into the flow control component 2, and then flows along the inner groove 11 into the bottom chamber 34. By continuously supplying water to the brush head 3, users can simultaneously rinse and scrub with the cleaning brush, thereby improving cleaning efficiency.

[0030] To adjust the position of the flow control component 2 along the length of the brush handle 1, the adjustment component can be slidably or threadedly connected along the length of the brush handle 1. By adjusting the position of the flow control component 2 along the length of the brush handle 1, the flow rate of water inside the inner tank 11 is controlled, thereby controlling the amount of water flowing into the brush head 3. This allows users to quickly adjust the water output of the cleaning brush according to the needs of the cleaning scenario, ensuring cleaning efficiency and improving water utilization while preventing water waste. The flow control component 2 includes a pipe connector 21 and a moving pipe 22. One end of the pipe connector 21 is connected to the moving pipe 22, and the other end is connected to the flexible hose 4. External water flows along the inlet hose 4 to the pipe connector 21 and then into the moving pipe 22. The end of the moving pipe 22 near the brush handle 1 is provided with an internally threaded cylinder 223, and the brush handle 1 is provided with an externally threaded end 13 that matches the internally threaded cylinder 223. The brush handle 1 is provided with a handle 12, which is provided with an ergonomic foam sleeve for easy gripping and to prevent slippage. With the external thread end 13 and the internal thread cylinder 223 engaged, the user can adjust the position of the flow control component 2 relative to the brush rod 1 by gripping the moving tube 22 and the handheld part 12 respectively. The moving tube 22 can also be connected to the brush rod 1 via a sliding connection. The brush rod 1 has a groove along its length, and the moving tube 22 has a guide block that engages with the groove. The moving tube 22 moves along the length of the brush rod 1 through the engagement of the guide block and the groove. The moving tube 22 has a through plate 222 inside, with multiple through holes 2221 distributed on the through plate 222. The through plate 222 has an integrated cone 2222, and the brush rod 1 has a through opening 111 corresponding to the position of the cone 2222. Water flows through the through holes 2221 and the through opening 111 in sequence, and then enters the inner tank 11. The cone 2222 moves along with the moving tube 22. When the moving tube 22 approaches the brush rod 1, the cone 2222 gradually passes through the opening 111, reducing the water flow area of ​​the opening 111 and thus reducing the amount of water entering the inner tank 11. When the moving tube 22 moves away from the brush rod 1, the cone 2222 gradually moves away from the opening 111, increasing the water flow area of ​​the opening 111 and thus increasing the amount of water entering the inner tank 11. The end face of the opening 111 near the moving tube 22 has a positioning groove 112, and a retaining sleeve 15 is provided on the positioning groove 112. The retaining sleeve 15 is made of a high-polymer elastic material (rubber, PU, ​​etc.) and has a conical hole that matches the cone 2222. When water is not needed to flow into the inner tank 11, the retaining sleeve 15 can completely fit the cone 2222, improving the sealing performance of the cone 2222 to the opening 111 and ensuring that water does not leak into the inner tank 11.

[0031] The end face of the internally threaded cylinder 223 near the brush rod 1 has a side edge 2231. A first limiting ring 14 is provided on the brush rod 1 corresponding to the side edge 2231, with the side edge 2231 located between the externally threaded end 13 and the first limiting ring 14. When the moving tube 22 moves along the length of the brush rod 1, the side edge 2231, integrated with the moving tube 22, limits the movement of the moving tube 22 to the distance between the externally threaded end 13 and the first limiting ring 14. This ensures that during the adjustment of the water flow of the brush head 3, the flow control component 2 does not detach from the brush rod 1 due to the moving tube 22 moving too far away from it, and also prevents irreversible deformation of the brush rod 1 and the through plate 222 caused by excessive external force when the moving tube 22 approaches the brush rod 1. A U-shaped sealing ring 2232 is provided on the side edge 2231. The U-shaped sealing ring 2232 covers the contact surface between the side edge 2231 and the through plate 222, the contact surface between the side edge 2231 and the brush rod 1, and the contact surface between the side edge 2231 and the first limiting ring 14. This ensures that no water leakage occurs between the flow control component 2 and the brush rod 1 as the moving tube 22 moves along the length direction of the brush rod 1.

[0032] The moving tube 22 has an integrated step 221 on the side near the pipe connector 21, and a filter screen 23 is provided on the side of the step 221 near the pipe connector 21. The filter screen 23 can prevent impurities in the water flow from entering the control components, inner tank 11, and brush head 3, ensuring the smooth flow of water inside the cleaning brush. The removable filter screen 23 is easy to remove and clean before being reinstalled on the moving tube 22. The filter screen 23 is arched and protrudes outward towards the pipe connector 21. The arched shape of the filter screen 23 increases its surface area and also helps the water flow to concentrate impurities towards the edge of the filter screen 23, preventing excessive impurities from clogging the filter screen 23 and ensuring its normal function.

[0033] The base plate 33 is concave, and the brush rod 1 is connected to the concave surface of the base plate 33. A brush block 31 is provided on the convex surface of the base plate 33 opposite to the concave surface. A first reinforcing rib 332 is provided on the concave surface of the base plate 33, and multiple evenly spaced second reinforcing ribs 331 are provided on the edges of the base plate 33. The concave shape of the base plate 33 facilitates increasing the brushing area of ​​the brush head 3 and allows the user to easily rotate the brush head 3 along the convex surface of the base plate 33, enabling the brush head 3 to perform brushing within a small space and improving its cleaning efficiency. The first reinforcing rib 332 and the second reinforcing ribs 331 enhance the strength of the base plate 33, ensuring the brush head 3 maintains a stable structure during cleaning. A water inlet pipe 32 is provided on the base plate 33, with one end threadedly connected to the brush rod 1 and communicating with the inner groove 11. A second limiting ring 322 is provided on the water inlet pipe 32 corresponding to the end of the brush rod 1 to prevent excessive torque during installation from causing threaded connection failure. The other end of the water inlet pipe 32 is connected to the bottom chamber 34, and a valve 321 is provided on the water inlet pipe 32. The valve 321 can control the water flow into the bottom chamber 34. When the flow control component 2 fails, the valve 321 can continue to control the flow rate of water entering the brush head 3 to ensure the function of controlling the water output of the cleaning brush. The bottom surface of the bottom chamber 34 is provided with multiple bottom pipes 342, and all of the bottom pipes 342 are inserted into the brush block 31. The diameter of the bottom pipes 342 gradually decreases along the direction towards the brush block 31. Since the bottom pipes 342 are tapered towards the brush block 31, it is easy for the bottom pipes 342 to be inserted into the brush block 31. All of the bottom pipes 342 are connected to the bottom chamber 34, and multiple evenly spaced side holes 3421 are provided on the circumference of the bottom pipes 342. The side holes 3421 can improve the water output efficiency of the bottom pipes 342. Water flows through the bottom pipe 342 into the brush block 31 to keep it moist and ensure the cleaning effect of the brush head 3. The brush block 31 can be directly fixed to the base plate 33 via the bottom pipe 342. This detachable connection allows for easy replacement of the brush block 31, maintaining the cleaning effect of the cleaning brush. The bottom chamber 34 is equipped with a feed pipe 341 that connects to the outside, and the feed pipe 341 has a detachable end cap. Cleaning agent can be added to the bottom chamber 34 through the feed pipe 341, allowing the cleaning agent and water to mix within the bottom chamber 34, thereby improving the cleaning effect of the cleaning brush.

[0034] The working principle of this invention is as follows: Water flows along the hose 4 into the inner groove 11 of the brush rod 1, and then flows along the inner groove 11 into the bottom chamber 34 of the brush head 3, allowing the cleaning brush to continuously output water. The flow control component 2 between the brush rod 1 and the hose 4 includes a moving tube 22. By controlling the position of the moving tube 22 on the brush rod 1, the distance between the cone 2222 and the opening 111 is adjusted, so that the water flow area of ​​the opening 111 changes with the movement of the moving tube 22, thereby achieving the effect of controlling the water output of the brush head 3.
