Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a 360-degree rotating water-cooled cleaning brush. Background Technology

[0002] A water-cooled cleaning brush is a highly efficient cleaning tool that integrates rinsing and scrubbing functions. Its core structure typically consists of a water-cooled brush head, a brush handle, and connecting components. The brush head, as the final outlet for the water flow, generally features a hollow design and connects to the brush handle via an internal pipe. The other end of the brush handle connects to an external water pipe, allowing water to flow from the pipe to the brush handle, then through the handle and distribute evenly across the brush head. This allows the water-cooled brush head to simultaneously clean items, thereby improving cleaning efficiency.

[0003] To ensure smooth communication between the brush handle and the brush head, conventional water-cooled cleaning brushes are typically one-piece structures or fixed connections. However, when cleaning narrow spaces or complex curved surfaces, the brush head cannot rotate flexibly relative to the brush handle, forcing the operator to frequently adjust their posture or change cleaning direction. This increases physical exertion and may also affect cleaning effectiveness due to limited viewing angle, making it inconvenient to use. Utility Model Content

[0004] To overcome the technical problem that the brush head of the existing water-cooled cleaning brush cannot rotate flexibly, this utility model provides a water-cooled cleaning brush that can rotate 360 ​​degrees.

[0005] To achieve the above objectives, this utility model proposes a 360-degree rotating water-cooled cleaning brush, including a handle and a brush head. The brush head has an internal cavity, and the handle has a water pipe communicating with the internal cavity. One end of the handle has a detachable connector, and the end of the connector away from the handle has a positioning ring. The brush head has an annular groove that matches the positioning ring, the positioning ring has annular teeth in its circumferential direction, and the annular groove has annular grooves in its circumferential direction that match the annular teeth.

[0006] Furthermore, the handle is hollow inside, and a side tube is provided at the end of the handle near the brush head. The water pipe enters the interior of the handle from the end of the handle and extends along the side tube. The end of the water pipe near the brush head is connected to the water delivery pipe on the brush head. The water delivery pipe is connected to the inner cavity, and the bottom surface of the inner cavity has multiple permeation holes arranged in an array.

[0007] Furthermore, the water supply pipeline includes a main pipe and secondary pipes. The main pipe is connected to the water pipe, and multiple evenly spaced secondary pipes are provided along the length of the main pipe. All of the secondary pipes are connected to the inner cavity.

[0008] Furthermore, the main pipe is equipped with a material pipe, one end of which is connected to the main pipe, and the other end is equipped with a detachable cleaning tank.

[0009] Furthermore, the connector has a threaded end near the grip, and the grip has an internal thread that matches the threaded end; the end of the threaded end has a limiting ring that matches the grip.

[0010] Furthermore, the interior of the cavity is equipped with multiple columns evenly distributed in an array, with each end of the columns being integrated with the top and bottom surfaces of the cavity, respectively.

[0011] Furthermore, the brush head has a freely opening and closing side cover, through which the inner cavity can communicate with the outside world; the edge of the side cover is provided with a sealing ring, and the brush head has a sealing groove corresponding to the position of the sealing ring.

[0012] Furthermore, the side of the grip bar is provided with a side groove, one end of which is connected to the interior of the grip bar, and the other end is an open end that extends outward along the radial direction of the grip bar; a slidingly connected retaining plate is provided inside the side groove.

[0013] Furthermore, multiple slots are provided on both symmetrical sides of the side groove, and multiple teeth that cooperate with the slots are provided on both sides of the card plate.

[0014] Furthermore, the card plate includes an integrated card block and a blade. The blade is located on the side of the card block closest to the water pipe, and a handle is located on the side furthest from the water pipe.

[0015] The beneficial effects of this invention are as follows: Compared with common water-cooled cleaning brushes, this invention introduces external water flow to the brush head through a water pipe on the handle. The handle no longer serves the function of conveying water flow; it is only mechanically connected to the brush head. Through the cooperation of the positioning ring and the annular groove, the brush head can rotate 360 ​​degrees relative to the handle. Simultaneously, the cooperation of the annular retaining teeth and the annular retaining groove ensures that the brush head is stably maintained at a certain angle relative to the handle, improving the ease of use of the cleaning brush.

[0028] 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.

[0029] 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.

[0030] like Figure 1-9As shown, this utility model proposes a 360-degree rotating water-cooled cleaning brush, including a handle 1 and a brush head 2. The brush head 2 has an inner cavity 213, and the handle 1 has a water pipe 11 communicating with the inner cavity 213. One end of the handle 1 has a detachable connector 23, and the end of the connector 23 near the handle 1 has a threaded end 231. The handle 1 has an internal thread 14 that mates with the threaded end 231. The free disassembly or assembly of the handle 1 and the connector is achieved through the engagement of the threaded end 231 and the internal thread 14 on the handle 1. The end of the threaded end 231 has a limiting ring 2311 that mates with the handle 1. When the handle 1 is in contact with the limiting ring 2311, it indicates that the handle 1 has been assembled to its limit position, preventing damage to the threads caused by applying excessive torque. The end of the connector 23 furthest from the handle 1 is provided with a positioning ring 232. The brush head 2 is provided with an annular groove 211 that matches the positioning ring 232. The positioning ring 232 is provided with an annular retaining tooth 2321 in the circumferential direction, and the annular groove 211 is provided with an annular retaining groove 212 that matches the annular retaining tooth 2321 in the circumferential direction. Compared with the traditional water-passing cleaning brush that guides water flow to the brush head 2 through the brush handle, this utility model proposes a 360-degree rotating water-passing cleaning brush in which one end of the water pipe 11 is connected to an external water pipe 11, and the other end passes through the handle 1 and is connected to the brush head 2. The external water flow enters the brush head 2 along the water pipe 11, and the handle 1 no longer plays a guiding role, so it can be movably connected to the brush head 2. The detachable connector 23 not only ensures a stable connection between the brush head 2 and the handle 1, but also facilitates disassembly and maintenance. The positioning ring 232 and the annular groove 211 work together to allow the brush head 2 to rotate 360 ​​degrees relative to the handle 1. Simultaneously, the engagement of the annular retaining teeth 2321 and the annular groove 212 ensures the brush head 2 maintains a stable angle relative to the handle, enhancing ease of use. The freely rotating brush head 2 overcomes the limitations of traditional water-cooled cleaning brushes with their fixed angle, allowing it to reach into narrow crevices (such as bathroom corners and furniture seams). The rotating motion covers any direction, cleaning hard-to-reach areas that traditional water-cooled cleaning brushes cannot reach. Users can thoroughly clean dirt without frequently adjusting their posture or changing cleaning direction, saving energy and time and improving cleaning efficiency.

[0031] The handle 1 is hollow inside, and a side tube 13 is provided at the end of the handle 1 near the brush head 2. A water tube 11 enters the interior of the handle 1 from the end of the handle 1 and extends along the side tube 13. The water tube 11 is located inside the handle 1, preventing excessive friction or tangling during movement and improving ease of use. The end of the water tube 11 near the brush head 2 is connected to a water supply tube 11 on the brush head 2. The water supply tube 11 is located at the top of the inner cavity 213 and is connected to the inner cavity 213. Bristles are provided on the bottom surface of the brush head 2 away from the water supply tube 11. Multiple permeation holes 2131 are arranged in an array on the bottom surface of the inner cavity 213, connecting the inner cavity 213 to the outside. External water flows along the water tube 11 into the interior of the handle 1, flows into the inner cavity 213 of the brush head 2, and finally flows out of the brush head 2 through the permeation holes 2131 at the bottom of the inner cavity 213. The water supply pipes 11 include a main pipe 221 and secondary pipes 222. The main pipe 221 is connected to the water pipe 11. Multiple evenly spaced secondary pipes 222 are arranged along the length of the main pipe 221, and all secondary pipes 222 are connected to the inner cavity 213. Water from the water pipe 11 first enters the main pipe 221, and then is evenly distributed to various areas of the inner cavity 213 through the secondary pipes 222 to ensure consistent pressure throughout the inner cavity 213. This ensures a stable and consistent flushing effect when water flows out from the permeation holes 2131 on the bottom surface of the inner cavity 213. A feed pipe 223 is provided on the main pipe 221. One end of the feed pipe 223 is connected to the main pipe 221, and the other end is equipped with a detachable cleaning tank 2231, which stores cleaning agent. The feed pipe 223 is equipped with a one-way valve. When it is necessary to add cleaning agent, close the one-way valve and assemble the open end of the cleaning tank 2231 with the feed pipe 223. After opening the one-way valve, the cleaning agent flows out from the cleaning tank 2231 and flows into the main pipe 221 to mix with the water flow, thereby improving the cleaning ability during the flushing process.

[0032] The inner cavity 213 contains a plurality of evenly distributed columns 2132, each with its ends integrated into the top and bottom surfaces of the inner cavity 213. When the user operates the handle 1 to apply external force to the brush head 2, the brush head 2, with its inner cavity 213, bears considerable pressure. Over time, this can easily lead to deformation. The evenly distributed columns 2132 enhance the structural strength of the inner cavity 213, preventing deformation of the brush head 2 due to prolonged use and ensuring the stability of water flow within the inner cavity 213. The brush head 2 has a freely opening and closing side cover 214, through which the inner cavity 213 communicates with the outside. With prolonged use, the inner cavity 213 can easily accumulate excessive impurities. Opening the side cover 214 facilitates flushing out these accumulated impurities, preventing them from clogging the permeation holes 2131. The side cover 214 is provided with a sealing ring at its edge, and the brush head 2 is provided with a sealing groove at the position of the sealing ring. The sealing ring and the sealing groove cooperate to improve the sealing performance of the side cover 214 when closed, and prevent water leakage during normal use of the brush head 2.

[0033] The handle 1 has a side groove 121 on its side. One end of the side groove 121 communicates with the interior of the handle 1, and the other end is an open end that extends radially outward along the handle 1. A slidingly connected retaining plate 12 is provided inside the side groove 121. Different cleaning scenarios have different requirements for the water output intensity of the brush head 2. The retaining plate 12 slides along the side groove 121. When the retaining plate 12 moves radially towards the water pipe 11 along the handle 1 and squeezes the water pipe 11, the water flow through the water pipe 11 is reduced. The user can operate the handle 1 in this way to control the water output of the water pipe 11, and thus adjust the water pressure of the brush head 2. The retaining plate 12 includes an integrated retaining block 124 and a blade 125. The blade 125 is provided on the side of the retaining block 124 near the water pipe 11, and a handle 123 is provided on the side away from the water pipe 11. The user can control the depth of the retaining plate 12 in the side groove 121 by applying pulling or pushing force to the handle 123. The blade 125 reduces the contact area between the clamping plate 12 and the water pipe 11, making it easier to concentrate the pressure applied by the clamping plate 12 to the water pipe 11, thus facilitating the clamping plate 12 to cut off the flow rate of water in the water pipe 11. Multiple slots 122 are provided on both symmetrical sides of the side groove 121, and multiple teeth 1241 that engage with the slots 122 are provided on both sides of the clamping plate 12. Through the engagement of the teeth 1241 and the slots 122, the clamping plate 12 can be stably fixed at different depths in the side groove 121, eliminating the need for continuous manual control of the clamping plate 12's position and allowing for continuous control of the water flow rate from the brush head 2.

[0034] The working principle of this invention is as follows: Water flows into the brush head 2 through the water pipe 11. The handle 1 is rotatably connected to the brush head 2 via the connector 23, allowing the brush head 2 to rotate 360 ​​degrees relative to the handle 1. The engagement of the annular retaining teeth 2321 on the connector 23 with the annular retaining groove 212 on the brush head 2 ensures that the brush head 2 maintains a stable angle relative to the handle 1. The water flow rate from the water pipe 11 can be controlled by adjusting the depth of the retaining plate 12 inserted into the side groove 121.
