Description

Technical Field

[0001] This application relates to the field of brush technology, and more specifically, to a water-passing brush. Background Technology

[0002] Brushes are widely used tools, often used for cleaning surface dirt, such as tiles, floors, and glass. However, when using a brush to clean surface dirt, it is generally necessary to first wet the surface to be cleaned, and then rub the brush bristles back and forth on the surface to remove the dirt, which is inconvenient. Therefore, people have designed a water-cooled brush that combines rinsing and brushing, which can directly rinse water onto the dirt surface as needed.

[0003] The structure of the product can refer to a water brush disclosed in Chinese Patent (CN205040904U), which includes a brush rod and a brush head installed at the front end of the brush rod. The brush rod has an axial water inlet channel inside. The product is characterized in that: a fixed cylinder is installed at the rear end of the brush rod, and a water flow regulating valve for adjusting the water flow of the axial water inlet channel is installed inside the fixed cylinder. An operating handle for opening and closing the water flow regulating valve is installed on the fixed cylinder.

[0004] In the above structure, because the brush rod has an axial water inlet channel inside, the brush head must be tightly installed on the brush rod in order to pass water to the brush head; as a result, people cannot adjust the angle between the brush head and the brush rod as needed during use, causing inconvenience.

[0005] Therefore, the purpose of this utility model is to provide a water brush that can change the angle of the brush head. Utility Model Content

[0006] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0007] To address the technical problems mentioned in the background section, some embodiments of this application provide a water-passing brush, including a brush rod and a brush head with a hollow inner cavity. A water pipe is disposed inside the brush rod, and the brush head is provided with bristles and a water passage hole. A through hole is provided on the brush rod, and the water pipe passes through the through hole and connects to the water passage hole. One end of the brush rod is threadedly connected to a first threaded rod, and a first steering head is fixedly disposed on the first threaded rod. The brush head is threadedly connected to a second threaded rod, and a second steering head is fixedly disposed on the second threaded rod. The second steering head is connected to the first steering head through a screw. A rotating block is fixedly disposed at one end of the screw, and the end of the screw away from the rotating block passes through the first and second steering heads and is fixed by a nut.

[0008] During operation, since the water pipe is connected to the water passage on the brush head, as long as the water pipe is connected to an external water supply device, water can be sprayed onto the surface of the object being cleaned while using the brush. Because it is equipped with a first threaded rod, a first steering head, a second threaded rod, and a second steering head, the angle of the brush head relative to the brush rod can be changed by changing the relative connection angle of the first steering head and the second steering head, thus achieving the angle adjustment of the brush head. Since the water pipe passes through the through hole of the brush rod and then connects to the water passage on the brush plate, changing the angle of the brush head will not affect the water flow effect of the water pipe.

[0009] Furthermore, a first gear ring is formed on the first steering head, and a second gear ring capable of meshing with the first gear ring is formed on the second steering head.

[0010] Furthermore, the side wall portion of the first steering head is recessed to form a first connecting cavity, the bottom wall portion of the first connecting cavity protrudes to form a first fixing platform, and the first fixing platform portion extends through to form a first sliding groove;

[0011] The side wall of the second steering head is recessed to form a second connecting cavity, the bottom wall of the second connecting cavity protrudes to form a second fixing platform, and the second fixing platform extends through to form a second sliding groove.

[0012] The screw is slidably disposed within the first and second slide grooves.

[0013] Furthermore, the side wall portion of the first steering head is recessed to form a hexagonal groove, and the nut is a hexagonal nut corresponding to the shape of the hexagonal groove.

[0014] Furthermore, a first rotating ring is rotatably mounted on the first fixed platform, and a second rotating ring is rotatably mounted on the second fixed platform. The first rotating ring and the second rotating ring are fixedly connected by an elastic element.

[0015] Furthermore, the elastic element is a spring, which is sleeved outside the screw.

[0016] Furthermore, a Y-shaped tee pipe is connected to one end of the water pipe near the through hole. There are two through holes, and a spray head is fixedly installed inside the through holes. The spray head is connected to the tee pipe through a connecting pipe.

[0017] Furthermore, the brush rod is a multi-section telescopic rod, with the sections interlocking and a limiting joint between adjacent sections.

[0018] The beneficial effects of this application are as follows:

[0019] 1. The brush rod and brush head are connected by a first threaded rod, a second threaded rod, a first steering head, and a second steering head. The angle of the brush head can be changed by changing the relative connection angle of the first steering head and the second steering head. It is convenient to use and will not affect the water flow of the water pipe.

[0020] Second, by setting a first gear ring and a second gear ring, when the screw tightens and fixes the second steering head to the first steering head, the first gear ring can mesh with the second gear ring, making the connection between the first steering head and the second steering head more secure and preventing the brush head angle from deflecting during use.

[0021] Third, by setting up a first rotating ring, a second rotating ring, and an elastic element, the elastic element can always pull the second steering head to fit against the first steering head, thus preventing the second steering head from suddenly rotating under the gravity of the brush head when the screw is loosened, which would cause a significant change in the angle of the brush head.

[0036] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] A water-cooling brush includes a brush rod 1 with a hollow inner cavity and a brush head 2. The brush rod 1 is a multi-section telescopic rod, with the sections interlocking with each other. A limiting joint 29 is provided between adjacent sections to fix the relative position between adjacent sections, thereby fixing the telescopic length of the brush rod 1. A water pipe 3 is provided inside the brush rod 1. The brush head 2 is provided with bristles 4 and a water passage hole 5. A through hole 6 is provided on the side wall of the brush rod 1, penetrating into the hollow inner cavity of the brush rod 1. The brush head 2 is connected to one end of the brush rod 1. The water pipe 3 extends into the inner cavity of the brush rod 1 from the end of the brush rod 1 away from the brush head 2, passes through the through hole 6, and then connects to the water passage hole 5 on the brush head 2. In use, the water pipe 3 only needs to be connected to an external water supply device to rinse the surface of the object being cleaned while using the brush.

[0038] More specifically, one end of the brush rod 1 is threadedly connected to a first threaded rod 7, and a first steering head 8 is fixedly mounted on the end of the first threaded rod 7 away from the brush rod 1. A second threaded rod 9 is threadedly connected to the brush head 2, and a second steering head 10 is fixedly mounted on the end of the second threaded rod 9 away from the brush head 2. The second steering head 10 is connected to the first steering head 8 via a screw 11. Specifically, a rotating block 12 is fixedly mounted on one end of the screw 11, and the end of the screw 11 away from the rotating block 12 passes through the first steering head 8 and the second steering head 10 and is fixed by a nut 13. Specifically, the side wall portion of the first steering head 8 is concave. A first connecting cavity 16 is formed. The bottom wall of the first connecting cavity 16 protrudes to form a first fixing platform 17. The first fixing platform 17 partially penetrates to form a first sliding groove 18. The side wall of the second steering head 10 is recessed to form a second connecting cavity 19. The bottom wall of the second connecting cavity 19 protrudes to form a second fixing platform 20. The second fixing platform 20 partially penetrates to form a second sliding groove 21. The screw 11 is slidably disposed in the first sliding groove 18 and the second sliding groove 21. The side wall of the first steering head 8 is recessed to form a hexagonal groove 22. The nut 13 is a hexagonal nut 13 corresponding to the shape of the hexagonal groove 22.

[0039] After the screw 11 is inserted into the second slide groove 21 and the first slide groove 18 in sequence, the end of the screw 11 near the first steering head 8 is fixed with the nut 13. When the screw 11 is rotated, the hexagonal groove 22 will restrict the nut 13 from rotating with the screw 11, which can press the second steering head 10 against the first steering head 8, thereby fixing the relative position of the first steering head 8 and the second steering head 10. Therefore, by loosening the screw 11, the second steering head 10 can be rotated, thereby changing the angle of the brush head 2. After rotating the second steering head 10, the screw 11 can be tightened to fix the angle of the brush head 2. By tightening and loosening the screw 11, people can adjust the angle of the brush head 2 according to their needs, which is convenient to use. Since the water pipe 3 passes through the through hole 6 and is connected to the brush head 2, the change of the position of the brush head 2 will not affect the water flow effect of the water pipe 3.

[0040] More specifically, a first gear ring 14 is formed on the first steering head 8, and a second gear ring 15 that can mesh with the first gear ring 14 is formed on the second steering head 10. When the screw 11 is tightened to press the second steering head 10 against the first steering head 8, the first gear ring 14 can contact the second gear ring 15 to drive the second steering head 10 to rotate until the second gear ring 15 meshes with the first gear ring 14. The arrangement of the first gear ring 14 and the second gear ring 15 can further fix the relative position of the first steering head 8 and the second steering head 10, and prevent the position of the brush head 2 from rotating when using the flushing brush.

[0041] More specifically, a first rotating ring 23 is rotatably mounted on the first fixed platform 17, and a second rotating ring 24 is rotatably mounted on the second fixed platform 20. The first rotating ring 23 and the second rotating ring 24 are connected by an elastic element 25, which is a spring, and the spring is sleeved on the outside of the screw 11.

[0042] By setting the first rotating ring 23, the second rotating ring 24, and the spring, when the screw 11 is loosened, the spring can tighten the second steering head 10, so that the second steering head 10 is always in contact with the first steering head 8, thus preventing the second steering head 10 from rotating too much under the gravity of the brush head 2 when the screw 11 is loosened.

[0043] The end of the water pipe 3 near the through hole 6 is connected to a Y-shaped tee pipe 26. The brush head 2 is provided with two water holes 5. A spray head 27 is fixedly installed in the water holes 5. The spray head 27 is connected to the tee pipe 26 through a connecting pipe 28.

[0044] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
