Description

Technical Field

[0001] This utility model relates to the field of toilet brushes, specifically to a toilet brush with an anti-detachment brush head. Background Technology

[0002] In existing technology, toilets and latrines are generally cleaned using toilet brushes. Typical toilet brushes have bristles fixed to the brush head at the bottom of the handle, using the bristles for cleaning. However, the bristles and brush head, as well as the brush head and handle, cannot be detached. After use, when the toilet brush is placed against a wall or stored on its base, dirt and water residue on the brush head and bristles cannot be thoroughly cleaned, easily leading to bacterial growth and unpleasant odors. Therefore, there is a need for a toilet brush with an easily detachable brush head that can be replaced as needed. Utility Model Content

[0003] One objective of this invention is to provide a toilet brush with an anti-detachment brush head that solves the aforementioned problems.

[0004] To achieve the above-mentioned objectives, this utility model is implemented through the following technical solutions:

[0005] A toilet brush with an anti-detachment brush head includes a handle and a brush head. The handle and the brush head are detachably connected. The handle has a clamping opening for mounting the brush head. The brush head has a protrusion, the size of which is larger than the size of the clamping opening. A first clamp and a second clamp are provided on both sides of the clamping opening. When the first clamp and the second clamp rotate relative to each other and open, the clamping opening becomes larger, and the protrusion enters the clamping opening. When the first clamp and the second clamp move closer to each other, the protrusion is limited and fixed by the clamping opening. The handle has a positioning part for limiting the mounting position of the protrusion. The positioning part prevents the protrusion from moving and causing the first clamp or the second clamp to rotate and open, thus preventing the clamping opening from becoming larger. The detachable connection between the brush handle and the brush head allows for immediate installation and removal of the brush head before and after use, preventing the toilet brush from emitting odors when idle. During installation, there is a gap between the second clamp and the brush handle. When the brush head moves along the direction of the first clamp, the second clamp is located behind the brush head's movement direction. The second clamp pushes the brush head forward, which can cause it to slightly open due to the installation gap. The friction between the brush head and the toilet increases the pushing force between the second clamp and the brush head, potentially causing the brush head to fall off due to the second clamp opening. The positioning part prevents the brush head from pushing the second clamp open during use, thus preventing the brush head from falling off during daily use.

[0006] Preferably, the positioning part is fixedly disposed on the first clamp, and the second clamp is provided with a first clamping cavity. The first clamping cavity communicates with the clamping opening, and the width of the first clamping cavity is greater than the width of the clamping opening to accommodate the protrusion. The positioning part extends into the first clamping cavity and prevents the protrusion from moving towards the second clamp. A portion of the first clamp and a portion of the second clamp together form the clamping opening. The protrusion is clamped between the first clamp and the second clamp. The rear side of the protrusion extends into the first clamping cavity and is blocked by the portion of the positioning part located in the first clamping cavity. When the brush head moves forward to perform cleaning work, the thrust between the protrusion in the clamped installation state and the second clamp decreases or is blocked by the positioning part, so that the protrusion and the second clamp no longer push against each other, thereby preventing the brush head from falling off.

[0007] Preferably, the positioning part includes a first positioning surface and a second positioning surface. The first positioning surface and the second positioning surface limit the protrusion in different directions. The first positioning surface prevents the protrusion from moving towards the second clamp, and the second positioning surface prevents the protrusion from moving into the inner cavity of the brush handle. The arrangement of the first positioning surface and the second positioning surface prevents the second clamp from opening during brush head cleaning and also prevents the brush head from wobbling relative to the inside and outside of the brush handle.

[0008] Preferably, the positioning part has an arc surface with a hook-shaped cross-section. The first positioning surface and the second positioning surface are formed at two different positions on the upper and lower parts of the arc surface, respectively. The arc surface of the positioning part can guide the entry of the protrusion when clamping the brush head, so that the protrusion automatically abuts and limits itself against the positioning part along the arc surface after passing through the clamping opening.

[0009] Preferably, the middle portion of the second clamp is rotatably connected to the brush handle or the first clamp along the first pivot axis. The positioning portion also has an anti-rotation part, and the second clamp abuts against the anti-rotation part to limit the maximum angle of rotation of the second clamp away from the first clamp. This allows the positioning portion to simultaneously serve as a brush head anti-dislodgement positioning element and a second clamp rotation limiter, simplifying the internal structure of the brush handle.

[0010] Preferably, the first clamp is integrally formed or fixedly connected to the positioning part. The first clamp has a second clamping cavity, which communicates with the clamping opening and the first clamping cavity. The end of the positioning part extends into the second clamping cavity. When the brush head is installed on the brush handle, the positioning part guides the front end of the protrusion into the second clamping cavity. The positioning part supports the rear end of the protrusion, preventing the protrusion from moving back and forth. A portion of the first clamp and a portion of the second clamp together form the clamping opening. The protrusion is clamped between the first clamp and the second clamp. The curvature or slope of the positioning part guides the protrusion passing through the clamping opening to automatically move to a position where it partially extends into the second clamping cavity. After the second clamp rotates and closes, it covers the other part of the protrusion.

[0011] Preferably, the brush handle further includes a handle section, which is a one-piece hollow tube. The front end of the handle section is integrally formed with the first clamp. An inclined angle is provided between the handle section and the first clamp. The first clamp has a first opening in the extending direction of the handle section. The rear end of the handle section has a second opening communicating with the first opening. A control component is provided between the handle section and the first clamp. The control component includes a switch, a push rod, and a spring. The push rod enters the handle section through one of the first opening and the second opening. The switch drives the push rod to move back and forth, thereby moving the second clamp and installing and removing the brush head. Conventional toilet brushes use an upper and lower cover connection, making it easy for sewage and waste to enter the toilet brush cavity through the installation gap between the upper and lower covers and difficult to drain. The handle section is made of one-piece injection molding or a metal tube, preventing sewage and waste from entering the toilet brush and making it more hygienic.

[0012] Preferably, the rear end of the second clamp is provided with an elongated groove, and the front end of the push rod is rotatably mounted in the elongated groove. The push rod moves back and forth, causing the second clamp to rotate around the first pivot. During use, the clamping section will come into contact with sewage and dirt. By using the back and forth movement of the push rod to change the position of the second clamp, the hand can be prevented from coming into contact with sewage and dirt on the surfaces of the first and second clamps.

[0013] Preferably, the handle section has a through guide sleeve, and the guide sleeve and the handle section are on the same straight line to allow the push rod to pass through and restrict the forward and backward movement of the push rod. The push rod has a stop block, and the spring is installed between the guide sleeve and the stop block. The guide sleeve and the stop block support the front and rear sides of the spring respectively, so that the spring deforms when the push rod moves forward and backward. The guide sleeve supports the front end of the push rod, reducing the push rod's wobbling.

[0014] Preferably, the second clamp or the first clamping cavity is provided with a drain hole, through which water in the first clamping cavity can flow out. This facilitates the discharge of wastewater entering the first clamping cavity, thereby reducing odor and bacterial growth.

[0015] The advantages of this utility model are: the detachable connection between the brush handle and the brush head allows for immediate installation and removal of the brush head before and after use, preventing the toilet brush from emitting odors when idle; the positioning part prevents the second clamp from opening during use, thus preventing the brush head from falling off during daily use; the detachable connection between the brush handle and the brush head is achieved through a control component, allowing for immediate installation and removal of the brush head before and after use, preventing the toilet brush from emitting odors when idle; while conventional toilet brushes use an upper and lower cover connection, making it easy for sewage and waste to enter the toilet brush cavity through the installation gap between the upper and lower covers and difficult to drain, the handle section is made of one-piece injection molding or metal tubing, preventing sewage and waste from entering the toilet brush, making it more hygienic.

[0025] like Figure 1-7 A toilet brush with an anti-detachment brush head includes a handle 1 and a brush head 2. The handle 1 and the brush head 2 are detachably connected. The handle 1 is provided with a clamping opening 3 for installing the brush head 2. The brush head 2 is provided with a protrusion 4. The size of the protrusion 4 is larger than the size of the clamping opening 3. A first clamp 5 and a second clamp 6 are provided on both sides of the clamping opening 3. When the first clamp 5 and the second clamp 6 rotate relative to each other and open, the clamping opening 3 becomes larger and the protrusion 4 enters the clamping opening 3. When the first clamp 5 and the second clamp 6 move closer to each other, the protrusion 4 is limited and fixed by the clamping opening 3. The handle 1 is provided with a positioning part 7 for limiting the installation position of the protrusion 4. The positioning part 7 prevents the protrusion 4 from moving and causing the first clamp 5 or the second clamp 6 to rotate and open, thus making the clamping opening 3 larger.

[0026] In this embodiment, the first clamp 5 and the second clamp 6 are distributed front to back, with the first clamp 5 located in front of the second clamp 6. The front-back direction is the extension direction of the brush handle 1. Grooves are provided at positions close to each other on the first clamp 5 and the second clamp 6, forming a clamping opening 3. The first clamp 5 is integrally formed or fixedly connected to the brush handle 1. The second clamp 6 is rotatably connected to the brush handle 1 or the first clamp 5. The first clamp 5 can rotate towards and away from the brush head 2 to release and clamp the brush head 2. In other embodiments, the positions of the first clamp 5 and the second clamp 6 can be interchanged, such as the second clamp 6 being located in front of the first clamp 5, while the remaining structure of the first clamp 5 and the second clamp 6 remains unchanged; alternatively, both the first clamp 5 and the second clamp 6 can be rotatably connected to the brush handle 1, allowing both the first and second brush heads 2 to rotate open and close during installation and removal.

[0027] Preferably, the positioning part 7 can be a part of the brush handle 1 or the first clamp 5. The positioning part 7 can also be a separate component fixedly installed on the brush handle 1 or the first clamp 5. When the second clamp 6 is installed, there is a gap between it and the brush handle 1 for installation and movement. When the brush head 2 moves along the direction of the first clamp 5 to brush, the second clamp 6 is located behind the brush head 2 in the direction of movement. The second clamp 6 pushes the brush head 2 forward to brush, which can easily cause the second clamp 6 to open slightly due to the installation gap. The friction between the brush head 2 and the toilet makes the pushing force between the second clamp 6 and the brush head 2 greater, causing the brush head 2 to fall off due to the opening of the second clamp 6. The positioning part 7 prevents the brush head 2 from pushing the second clamp 6 to open during use, thereby preventing the brush head 2 from falling off during daily use.

[0028] In this embodiment, the positioning part 7 is fixedly disposed on the first clamp 5, and the second clamp 6 is provided with a first clamping cavity 8. The first clamping cavity 8 is connected to the clamping opening 3, and the width of the first clamping cavity 8 is greater than the width of the clamping opening 3 to accommodate the protrusion 4. The positioning part 7 extends into the first clamping cavity 8, and the positioning part 7 prevents the protrusion 4 from moving towards the second clamp 6.

[0029] Preferably, the brush head 2 includes a fixed end 9 and a wiping section 10 that are fixedly connected. The fixed end 9 is provided with an outwardly extending protrusion 4. A neck 11 with a reduced size is provided between the protrusion 4 and the fixed end 9. The size of the protrusion 4 is larger than the size of the clamping opening 3. The size of the neck 11 is adapted to the size of the clamping opening 3. The second clamp 6 and the first clamp 5 open relative to each other. The protrusion 4 can pass through the clamping opening 3. The neck 11 is located at the position of the clamping opening 3. When the first clamp 5 and the second clamp 6 are rotated to close, the neck 11 is clamped by the clamping opening 3. The protrusion 4 is located inside the clamping opening 3. Due to the size difference between the protrusion 4 and the clamping opening 3, the protrusion 4 cannot leave the clamping opening 3.

[0030] In this embodiment, the positioning part 7 includes a first positioning surface 12 and a second positioning surface 13. The first positioning surface 12 and the second positioning surface 13 limit the protrusion 4 in different directions. The first positioning surface 12 prevents the protrusion 4 from moving towards the second clamp 6, and the second positioning surface 13 prevents the protrusion 4 from moving into the inner cavity of the brush handle 1. The first positioning surface 12 is approximately parallel to the clamping opening 3, and the second positioning surface 13 is located below the first positioning surface 12. The lower end of the second positioning surface 13 extends towards the clamping opening 3 so that the first positioning surface 12 and the second positioning surface 13 together form a hook. The hook shape of the first positioning surface 12 prevents the protrusion 4 from approaching or abutting the second clamp 6.

[0031] In other embodiments, the positioning part 7 may also be configured as a positioning groove or positioning hole, with the protrusion 4 entering the positioning groove or positioning hole, and the sidewall of the positioning groove or positioning hole preventing the protrusion 4 from approaching or abutting the second chuck 6.

[0032] Preferably, the positioning part 7 has an arc surface with a hook-shaped cross-section. The upper and lower positions of the arc surface respectively form a first positioning surface 12 and a second positioning surface 13. The arc surface of the positioning part 7 guides the entry of the protrusion 4 when clamping the brush head 2, allowing the protrusion 4 to automatically abut and be positioned against the positioning part 7 after passing through the clamping opening 3. Alternatively, the positioning part 7 can be configured as an angled surface, with the two surfaces extending in different directions forming the first positioning surface 12 and the second positioning surface 13.

[0033] In the above embodiment, the middle part of the second clamp 6 is rotatably connected to the brush handle 1 or the first clamp 5 along the first rotating shaft 14. The positioning part 7 is also provided with an anti-rotation part 15, and the second clamp 6 abuts against the anti-rotation part 15 to limit the maximum angle of rotation of the second clamp 6 away from the first clamp 5. This allows the positioning part 7 to simultaneously serve as the anti-dislodgement positioning of the brush head 2 and the rotation limiting function of the second clamp 6, thereby simplifying the structure inside the brush handle 1.

[0034] Preferably, the first clamp 5 is integrally formed or fixedly connected with the positioning part 7. The first clamp 5 is provided with a second clamping cavity 16. The second clamping cavity 16 is connected to the clamping port 3 and the first clamping cavity 8. The end of the positioning part 7 extends into the second clamping cavity 16. When the brush head 2 is installed on the brush handle 1, the positioning part 7 guides the front end of the protrusion 4 into the second clamping cavity 16. The positioning part 7 supports the rear end of the protrusion 4 and prevents the protrusion 4 from moving back and forth.

[0035] In the above embodiment, the brush handle 1 further includes a handle section 17, which is a hollow tube integrally formed. The front end of the handle section 17 is integrally formed with the first clamp 5. An inclined angle is provided between the handle section 17 and the first clamp 5. The first clamp 5 has a first opening 18 in the extending direction of the handle section 17. The rear end of the handle section 17 has a second opening 19 communicating with the first opening 18. A control component 20 is provided between the handle section 17 and the first clamp 5. The control component 20 includes a switch 21, a push rod 22 and a spring 23. The push rod 22 enters the handle section 17 from one of the first opening 18 and the second opening 19. The switch 21 drives the push rod 22 to move back and forth to move the second clamp 6, thereby installing and removing the brush head 2.

[0036] Specifically, the brush handle 1 is made of one-piece injection molding of plastic or made of seamless metal tube. Since the brush handle 1 is cleaned in a direction that is inclined relative to the surface to be cleaned during use, an inclined angle is set between the handle section 17 and the first clamp 5 so that the brush head 2 contacts the surface to be cleaned in a parallel or more closely fitted manner. In this embodiment, the handle section 17 and the first clamp 5 are made of one-piece molding of plastic. Compared with metal tube, the one-piece molding process of plastic is simpler and cheaper in processing the inclined clamping position. Moreover, under this processing method, by reducing or eliminating the installation gap on the brush handle 1, sewage and dirt are prevented from entering the cavity of the brush handle 1.

[0037] Preferably, the rear end of the second chuck 6 is provided with an elongated groove 24, and the front end of the push rod 22 is rotatably installed in the elongated groove 24. The push rod 22 moves back and forth, causing the second chuck 6 to rotate around the first rotating shaft 14.

[0038] In this embodiment, the second clamp 6 is rotatably mounted on the first clamp 5, and the first clamp 5 is fixedly mounted on the brush handle 1 or the front end of the brush handle 1 forms the first clamp 5. In use, the relative position or angle between the second clamp 6 and the first clamp 5 is changed by rotating the second clamp 6 to adjust the size of the clamping opening 3, thereby installing and removing the brush head 2.

[0039] Preferably, the handle section 17 is provided with a through guide sleeve 25. The guide sleeve 25 and the handle section 17 are located on the same straight line so that the push rod 22 can pass through and restrict the forward and backward movement direction of the push rod 22. The front end of the push rod 22 passes through the guide sleeve 25 in a close manner to reduce the shaking of the push rod 22 when it moves, so as to maintain the same straight line movement.

[0040] In this embodiment, the guide sleeve 25 and the push rod 22 are connected in a sealed manner. The sealing structure can be achieved by, for example, providing a sealing coating on the guide sleeve 25 or the push rod 22, and providing a sealing ring between the guide sleeve 25 and the push rod 22. The push rod 22 is provided with a stop block 26, and a spring 23 is installed between the guide sleeve 25 and the stop block 26. The guide sleeve 25 and the stop block 26 respectively support the front and rear sides of the spring 23, so that the spring 23 deforms when the push rod 22 moves back and forth.

[0041] Preferably, the second clamp 6 is provided with a drain hole 27 that communicates with the first clamping cavity 8, so as to facilitate the discharge of sewage entering the first clamping cavity 8, thereby reducing odor and bacterial growth.

[0042] The handle section 17 has a third opening 28 on its side, and the push rod 22 has a slot 29. The switch 21 passes through the third opening 28 and the slot 29 and is connected to the push rod 22.

[0043] In the above embodiments, a cover 30 is installed on both the first opening 18 and the second opening 19 to prevent the push rod 22 from disengaging from the brush handle 1.

[0044] During installation, first install the spring 23 on the push rod 22, then insert the push rod 22 and the spring 23 into the handle section 17 along the second opening 19 until the front end of the push rod 22 is connected to the long slot 24 of the second clamp 6. Insert the switch 21 along the third opening 28 and connect it to the slot 29 on the push rod 22. Finally, cover the cover 30 on the first opening 18 and the second opening 19 to complete the installation.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
