[0036] The elastic element is used to store force when moving through the hollow cavity and along the axial direction of the connecting rod 22, and to apply force to the drive assembly to reset the drive assembly when the force is released.

[0037] Optionally, the drive assembly includes a column and a grip portion disposed at one end of the column away from the cleaning component, and the spiral groove is disposed on the outer periphery of the column;

[0038] When the column extends into the hollow cavity and moves along the axial direction of the connecting rod 22, the limiting part slides along the spiral groove, causing the connecting rod to rotate.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0063] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0064] Example 1

[0065] Combined with appendix Figures 1 to 11 Instructions for using a toilet brush:

[0066] like Figure 1 As shown, this embodiment provides a toilet brush, a cleaning component 1, and a driving device 2. The driving device 2 includes a driving assembly 21 and a connecting rod 22. The cleaning component 1 is disposed at the end of the connecting rod 22. The driving assembly 21 is connected to the connecting rod 22 in a transmission manner. The driving assembly 21 moves along the axial direction of the connecting rod 22 to drive the connecting rod 22 to rotate, thereby driving the cleaning component 1 to rotate in order to clean the inner wall of the cavity to be cleaned.

[0067] The toilet brush provided in the above solution has a cleaning component 1 located at the end of the connecting rod 22. When the drive assembly 21 moves axially along the connecting rod 22, it drives the connecting rod 22 to rotate, thereby driving the cleaning component 1 to rotate and clean the inner wall of the cleaning chamber. The cleaning time can be adjusted by the user by moving the drive assembly 21 axially along the connecting rod 22 and by adjusting the speed. In this way, the transmission cooperation between the drive assembly 21 and the connecting rod 22 effectively improves the convenience and efficiency of cleaning.

[0068] Furthermore, after the toilet brush has been used and cleaned, the drive assembly 21 can be moved again along the axis of the connecting rod 22, causing the connecting rod 22 to rotate and thus drive the cleaning part 1 to rotate, so as to shake off the water on the cleaning part 1 and prevent the cleaning head from becoming moldy.

[0069] It should be noted that the cleaning component 1 is fixedly connected to or detachably connected to the connecting rod 22. When the drive assembly 21 moves axially along the connecting rod 22, causing the connecting rod 22 to rotate, the cleaning component 1 and the connecting rod 22 are in a fixed state. The drive assembly 21 can be sleeved on the outer periphery of the connecting rod 22, or it can be inserted into the inside of the connecting rod 22, or other methods can be used to achieve the above transmission process. No specific restrictions are made here.

[0070] The present invention provides two rotation modes for the transmission and engagement of the drive assembly 21 and the connecting rod 22;

[0071] See Figures 1-7 The first type of transmission connection method is illustrated in the following specific embodiment:

[0072] One of the connecting rod 22 and the drive assembly 21 is provided with a limiting part 213, and the other of the connecting rod 22 and the drive assembly 21 is provided with a spiral groove 214. When the drive assembly 21 moves along the length direction of the connecting rod 22, the limiting part 213 slides along the spiral groove 214, causing the connecting rod 22 to rotate. When the drive assembly 21 moves along the length direction of the connecting rod 22, the limiting part 213 slides along the spiral groove 214. Therefore, the movement between the drive assembly 21 and the connecting rod 22 is more convenient, the resistance is less, and the rotation of the connecting rod 22 is more convenient, resulting in higher rotation efficiency of the cleaning component 1.

[0073] Optionally, the outer wall of the connecting rod 22 is provided with a spiral groove 214, and the driving assembly 21 is sleeved on the outer periphery of the connecting rod 22 through the first through hole 215. The limiting part 213 is formed on the inner wall of the first through hole 215. When the driving assembly 21 moves axially along the outer periphery of the connecting rod 22, the limiting part 213 on the inner wall of the first through hole 215 can contact the spiral groove 214 after the driving assembly 21 is sleeved on the connecting rod 22, thereby driving the connecting rod 22 to rotate. In this way, the effective driving distance of the driving assembly 21 when moving forward is maximized.

[0074] It should be noted that the number of limiting parts 213 provided in the inner wall of the first through hole 215 can be one or more.

[0075] Optionally, such as Figure 3 As shown, an annular boss 216 with an elliptical hollow area is provided on the inner wall of the first through hole 215 near the end of the cleaning component 1. The annular boss 216 forms a limiting part 213. When the elliptical annular boss 216 slides along the spiral groove 214, the elliptical edge of the annular boss 216 slides with the groove, providing a certain oblique force to facilitate the rotation of the connecting rod 22.

[0076] Optionally, the drive assembly 21 includes a sleeve 211 sleeved on the outer periphery of the connecting rod 22 and a stop portion 212 fixedly disposed at one end of the sleeve 211 near the cleaning component 1. The stop portion 212 is used to isolate the sleeve 211 and the cleaning component 1 when the drive assembly 21 moves axially along the connecting rod 22 to a position near the cleaning component 1.

[0077] When the drive assembly 21 moves along the length of the connecting rod 22, the sleeve 211 is fitted onto the outer periphery of the connecting rod 22 and moves to drive the connecting rod 22 to rotate, causing the cleaning head to rotate. At the same time, the stop part 212 is fixed to the end of the sleeve 211 near the cleaning component 1. Therefore, when the drive assembly 21 moves axially along the connecting rod 22 to a position close to the cleaning component 1, the stop part 212 can isolate the sleeve 211 and the cleaning component 1, preventing sewage or other contaminants on the cleaning component 1 from splashing onto the sleeve 211 and causing inconvenience to the user.

[0078] It should be noted that the cross-sectional area of ​​the stop part 212 along the radial direction of the drive assembly 21 is greater than the cross-sectional area of ​​the sleeve 211 along the radial direction of the drive assembly 21. When the drive assembly 21 moves axially along the connecting rod 22 to a position close to the cleaning component 1, the stop part 212 can also prevent the user's hand from slipping forward from the sleeve 211, thus improving the stability during use.

[0079] Optionally, the first through hole 215 passes through the sleeve 211 and the abutment portion 212, and the limiting portion 213 is formed as an annular boss 216 with an elliptical hollow region on the inner wall of the first through hole 215 on the abutment portion 212. The annular boss 216 is provided on the inner wall of the first through hole 215 of the abutment portion 212, so that after the drive assembly 21 is sleeved on the connecting rod 22, it can contact the spiral groove 214, thereby driving the connecting rod 22 to rotate and maximizing the effective driving distance of the drive assembly 21 when it moves forward.

[0080] Optionally, the toilet brush also includes a handle 3, which is located at the end of the connecting rod 22 away from the cleaning component 1. When the connecting rod 22 rotates under the drive of the drive assembly 21, it rotates relative to the handle 3. The handle 3 is for the user to hold, and at the same time, the handle 3 and the connecting rod 22 can rotate relative to each other, reducing the influence of the handle 3 on the rotation of the rotating component during rotation and improving the user's convenience.

[0081] Optionally, the grip 3 has an inner cavity with one end open, and the end of the connecting rod 22 extends into the inner cavity and is connected to the inner wall of the inner cavity. By connecting the connecting rod 22 to the inner wall of the grip 3 inner cavity, there is no need to set additional structural components on the outside of the grip 3. When in use, the inner cavity is hollow, which can effectively reduce the use of materials and reduce production costs.

[0082] Optionally, the inner wall of the inner cavity of the grip 3 is provided with a first support portion 31, and the end of the connecting rod 22 is provided with a first limiting portion 213. When the end of the connecting rod 22 extends into the inner cavity, the first limiting portion 213 abuts against the first support portion 31 to restrict the end of the connecting rod 22 from detaching from the inner cavity of the grip 3.

[0083] It should be noted that the first support portion 31 can be a protrusion protruding from the inner wall of the inner cavity. The protrusion can be annular or distributed at intervals along the same plane. The first protrusion 41 can also be a groove on the inner wall. The groove has a bottom wall facing one end of the connecting rod 22. The first limiting portion 213 can cooperate with the bottom wall of the groove to restrict the end of the connecting rod 22 from disengaging from the inner cavity of the handle 3.

[0084] Optionally, the first support portion 31 is formed as an annular boss 216 on the inner wall of the cavity. The annular boss 216 is arranged along the same plane, so that when the connecting rod 22 is assembled with the handle 3, the first limiting portion 213 can be connected to the first support portion 31 after passing through the annular boss 216, and will not fall off due to the presence of other gaps, effectively improving the reliability of the assembly.

[0085] Optionally, the first limiting part 213 is formed as at least two spring arms 2211 disposed at the end of the connecting rod 22. A locking boss 2212 is provided on the outer side of each spring arm 2211. When the end of the connecting rod 22 extends into the inner cavity, the locking boss 2212 engages with the annular boss 216. When the connecting rod 22 is assembled with the grip 3, the spring arms 2211 can contract under force, allowing the connecting rod 22 to pass through the annular boss 216. The spring arms 2211 then return to their original shape under the action of elastic restoring force, thus effectively improving the assembly efficiency of the connecting rod 22 and the grip 3.

[0086] Optionally, a second limiting part 213 is provided on the outer wall of the connecting rod 22. When the end of the connecting rod 22 extends into the inner cavity, the end of the handle 3 abuts against the second limiting part 213 to limit the maximum displacement of the end of the connecting rod 22 into the inner cavity. The second limiting part 213 limits the length of the connecting rod 22 inserted into the inner cavity of the handle 3 when the connecting rod 22 is assembled with the drive assembly 21, thereby effectively improving the assembly efficiency and preventing the connecting rod 22 from sliding along the inner cavity of the handle 3.

[0087] Optionally, the second limiting part 213 is an annular step provided on the outer wall of the connecting rod 22. The annular step causes the connecting rod 22 to abut against the lower end face of the handle, preventing the connecting rod 22 from moving in the inner cavity.

[0088] Optionally, the connecting rod 22 is provided with a hollow cavity, and the inner wall of the hollow cavity is provided with a limiting part 213. The outer periphery of the driving assembly 21 is provided with a spiral groove 214. When the driving assembly 21 extends into the hollow cavity and moves along the axial direction of the connecting rod 22, the limiting part 213 slides along the spiral groove 214, causing the connecting rod 22 to rotate.

[0089] The specific working process of the first transmission and engagement method is as follows:

[0090] When in use, the user holds the toilet brush with the cleaning part 1 facing down, grasps the handle 3 with one hand and the sleeve 211 with the other, and pushes the sleeve 211 forward. At this time, the hand holding the sleeve 211 can rest against the stop part 212. The limiting part 213 inside the sleeve 211 or at the first through hole 215 cooperates with the spiral groove 214 on the connecting rod 22, causing the connecting rod 22 to rotate, thereby driving the cleaning part 1 to rotate to clean the inner wall of the cavity to be cleaned.

[0091] See Figures 8-10 The second type of transmission connection method is illustrated in the following specific embodiment:

[0092] like Figure 8 As shown, the connecting rod 22 has a hollow cavity, and the inner wall of the hollow cavity is provided with a limiting part 213. The outer periphery of the driving assembly 21 is provided with a spiral groove 214. When the driving assembly 21 extends into the hollow cavity and moves along the axial direction of the connecting rod 22, the limiting part 213 slides along the spiral groove 214, causing the connecting rod 22 to rotate. When the driving assembly 21 moves along the length direction of the connecting rod 22, the limiting part 213 slides along the spiral groove 214. Therefore, the movement between the driving assembly 21 and the connecting rod 22 is more convenient, the resistance is less, and the rotation of the connecting rod 22 is more convenient, resulting in higher rotation efficiency of the cleaning component 1.

[0093] Optionally, such as Figure 8 , Figure 9As shown, the limiting part 213 is a ball bearing disposed on the inner wall of the end of the hollow cavity away from the cleaning component 1. When the drive assembly 21 extends into the hollow cavity and moves along the axial direction of the connecting rod 22, the ball bearing can slide along the spiral groove 214, causing the connecting rod 22 to rotate. At the same time, since it can also rotate itself, it can better enhance the rotation efficiency of the connecting rod 22 and reduce the rotation resistance.

[0094] Optionally, a hemispherical groove is provided on the inner wall of the end of the hollow cavity away from the cleaning component 1. The ball is disposed in the hemispherical groove and protrudes from the inner wall of the hollow cavity. The hemispherical groove can both limit the movement of the ball and allow part of the ball to be exposed so as to cooperate with the drive assembly 21 for rotation.

[0095] Optionally, the toilet brush also includes a limiting sleeve 5, which is sleeved on the outer periphery of the connecting rod 22, with one end of the limiting sleeve 5 connected to the connecting rod 22 and the other end having an opening to allow the cleaning component 1 to extend out from the opening;

[0096] Furthermore, such as Figure 11 As shown, the limiting sleeve 5 is used to rotate relative to the connecting rod 22 when the connecting rod 22 rotates under the drive of the drive assembly 21, and when the cleaning component 1 is inserted into the cavity to be cleaned, the open end abuts against the edge of the cavity to be cleaned. When the limiting sleeve 5 abuts against the edge of the cavity to be cleaned, the limiting sleeve 5 can both support the toilet brush and prevent the cleaning component 1 from inserting too deeply into the inner wall of the cavity to be cleaned, making it difficult to pull out.

[0097] Optionally, the top end of the limiting sleeve 5 is provided with a second support portion 32, and one end of the connecting rod 22 is provided with a second limiting portion 213. The limiting sleeve 5 is connected to the outer periphery of the connecting rod 22 through the second support portion 32 and the second limiting portion 213, and the second support portion 32 and the second limiting portion 213 can rotate relative to each other. The second support portion 32 and the second limiting portion 213 cooperate to prevent the cleaning component 1 from being inserted too deeply into the inner wall of the cavity to be cleaned, making it difficult to pull out.

[0098] Optionally, a reset member 6 is provided between the connecting rod 22 and the drive assembly 21. The reset member 6 is used to reset the drive assembly 21 after it extends into the hollow cavity and moves axially along the connecting rod 22. After cleaning the inner cavity of the object to be cleaned with the toilet brush, the drive assembly 21 automatically resets via the reset member 6, reducing the user's operation steps and improving the user experience.

[0099] Optionally, the reset member 6 is an elastic member disposed in the hollow cavity of the connecting rod 22. One end of the elastic member abuts against the inner wall of the hollow cavity, and the other end abuts against the end of the drive assembly 21 extending into the hollow cavity. The elastic member is used to store force when moving through the hollow cavity and along the axial direction of the connecting rod 22, and to apply force to the drive assembly 21 when releasing force so that the drive assembly 21 resets.

[0100] Optionally, the drive assembly 21 includes a column and a gripping part disposed at the end of the column away from the cleaning component 1. A spiral groove 214 is disposed on the outer periphery of the column. When the column extends into the hollow cavity and moves along the axial direction of the connecting rod 22, the limiting part 213 slides along the spiral groove 214, causing the connecting rod 22 to rotate.

[0101] The specific working process of the second transmission and engagement method is as follows:

[0102] When in use, the user places the cleaning part 1 of the toilet brush downwards, places the limiting sleeve 5 against the edge of the cavity to be cleaned, holds the handle and pushes it downwards, so that the column is inserted into the middle of the connecting rod 22. The spiral groove 214 on the column and the ball on the connecting rod 22 cooperate to slide, causing the connecting rod 22 to drive the cleaning part 1 to rotate to clean the inner wall of the cavity to be cleaned.

[0103] Optionally, a locking structure is provided between the connecting rod 22 and the drive assembly 21. The locking structure is used to lock the drive assembly 21 onto the connecting rod 22 when the drive assembly 21 moves along the axial direction of the connecting rod 22 to one end away from the cleaning component 1.

[0104] When the drive assembly 21 moves along the axial direction of the connecting rod 22 to the end away from the cleaning component 1, the toilet brush is in an unused state. At this time, the drive assembly 21 is locked to the connecting rod 22 by the locking structure to prevent the connecting rod 22 from moving relative to the drive assembly 21 due to accidental contact.

[0105] Optionally, the locking structure includes a first protrusion 41 on one of the connecting rod 22 and the drive assembly 21, and a first groove 42 on the other; the drive assembly 21 is positioned on the connecting rod 22 by engaging the first groove 42 with the first protrusion 41.

[0106] The locking structure and the drive assembly 21 are respectively provided with a first protrusion 41 and a first groove 42. When the toilet brush is not in use, the drive assembly 21 is fixedly connected to the connecting rod 22 through the first protrusion 41 and the first groove 42, which prevents the drive assembly 21 from rotating due to accidental contact. This effectively improves the overall stability of the structure when the toilet brush is not in use and prevents the connecting rod 22 and the drive assembly 21 from moving relative to each other due to accidental contact.

[0107] Optionally, a handle 3 is provided at the end of the connecting rod 22 away from the cleaning component 1, and the drive assembly 21 is sleeved on the outer periphery of the connecting rod 22 through the first through hole 215 and can slide along the axial direction of the connecting rod 22;

[0108] Furthermore, the first protrusion 41 is disposed around the outer periphery of the grip 3, and the first groove 42 is disposed around the inner wall of the first through hole 215.

[0109] The grip 3 is located at one end of the connecting rod 22, and a first protrusion 41 is provided around the outer periphery of the grip 3. A first groove 42 is provided on the inner wall of the first through hole 215. The first protrusion 41 and the first groove 42 cooperate to realize the fixed connection between the drive assembly 21 and the grip 3, eliminating the need for additional connection structures and reducing production costs.
