[0063] Example 1

[0064] Combined with the drawings Figures 1 to 11 The toilet brush is described:

[0065] As Figure 1 shown, the utility model provides a kind of toilet brush, cleaning piece 1, driving device 2, driving device 2 includes driving assembly 21 and connecting rod 22, cleaning piece 1 is arranged at the end of connecting rod 22, driving assembly 21 is drivingly connected with connecting rod 22, and driving assembly 21 moves along the axial direction of connecting rod 22 to drive connecting rod 22 to rotate, to drive cleaning piece 1 to rotate to clean the inner wall of the cavity to be cleaned.

[0066] The toilet brush provided in the above scheme, the cleaning piece 1 is arranged at the end of the connecting rod 22, when the driving assembly 21 moves along the axial direction of the connecting rod 22 to drive the connecting rod 22 to rotate, the cleaning piece 1 is further driven to rotate to clean the inner wall of the cleaning cavity. The length of the cleaning time can be adjusted by the user moving the driving assembly 21 along the axial direction of the connecting rod 22 for a long time and at a high speed. In this way, the transmission cooperation between the driving assembly 21 and the connecting rod 22 effectively improves the convenience of cleaning and effectively improves the cleaning efficiency.

[0067] Further, when the toilet brush is used up and cleaned, the driving assembly 21 can be moved along the axial direction of the connecting rod 22 again, so that the connecting rod 22 rotates and further drives the cleaning piece 1 to rotate, so as to spin dry the moisture on the cleaning piece 1 and prevent the cleaning head from mildewing.

[0068] It should be noted that the cleaning piece 1 is fixedly connected or detachably connected with the connecting rod 22, and when the driving assembly 21 moves along the axial direction of the connecting rod 22 to drive the connecting rod 22 to rotate, the cleaning piece 1 is in a fixed state with the connecting rod 22. The driving assembly 21 can move on the outer periphery of the connecting rod 22 or can move in the inner part of the connecting rod 22, or other ways to achieve the above transmission process, which is not limited here.

[0069] The utility model driving assembly 21 and the transmission cooperation of connecting rod 22 two rotating modes;

[0070] Referring to Figures 1-7 , the first transmission cooperation mode, the specific implementation is as follows:

[0071] The connecting rod 22 and the driving assembly 21 are provided with a limiting part 213, and the other is provided with a spiral groove 214; 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, so that the connecting rod 22 rotates. 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 smaller, the rotation of the connecting rod 22 is more convenient, and the rotation efficiency of the cleaning piece 1 is higher.

[0072] Optionally, the outer wall of the connecting rod 22 is provided with a spiral groove 214, the driving assembly 21 is sleeved on the outer periphery of the connecting rod 22 through a first through hole 215, and the limiting part 213 is formed on the inner wall of the first through hole 215. When the driving assembly 21 is sleeved on the outer periphery of the connecting rod 22 and moves along the axial direction of the connecting rod 22, the limiting part 213 on the inner wall of the first through hole 215 can be in contact with the spiral groove 214 after the driving assembly 21 is sleeved on the connecting rod 22, and then the connecting rod 22 is driven to rotate, so that the effective driving distance of the forward movement of the driving assembly 21 is maximized.

[0073] It should be noted that the number of the limiting portions 213 arranged in the inner wall of the first through hole 215 can be one or more.

[0074] Optionally, as shown in Figure 3 the inner wall of the first through hole 215 is provided with an annular boss 216 with an elliptical hollow region near one end of the cleaning member 1, and the annular boss 216 forms the limiting portion 213. When the elliptical annular boss 216 slides along the spiral groove 214, the elliptical edge of the annular boss 216 slides along the sliding groove, providing a certain oblique force to facilitate the rotation of the connecting rod 22.

[0075] Optionally, the driving assembly 21 includes a sleeve 211 sleeved on the outer periphery of the connecting rod 22 and a blocking portion 212 fixedly arranged on the sleeve 211 near the cleaning member 1, and the blocking portion 212 is used to isolate the sleeve 211 and the cleaning member 1 when the driving assembly 21 moves axially along the connecting rod 22 to a position close to the cleaning member 1.

[0076] When the driving assembly 21 moves along the length direction of the connecting rod 22, the sleeve 211 is sleeved on the outer periphery of the connecting rod 22 to drive the connecting rod 22 to rotate to make the cleaning head rotate, and at the same time, the blocking portion 212 is fixed on the sleeve 211 near the cleaning member 1. Therefore, when the driving assembly 21 moves axially along the connecting rod 22 to a position close to the cleaning member 1, the blocking portion 212 can isolate the sleeve 211 and the cleaning member 1, avoiding the inconvenience caused to the user when the sewage on the cleaning member 1 splashes onto the sleeve 211.

[0077] It should be noted that the cross-sectional area of the blocking portion 212 along the radial direction of the driving assembly 21 is greater than the cross-sectional area of the sleeve 211 along the radial direction of the driving assembly 21, and when the driving assembly 21 moves axially along the connecting rod 22 to a position close to the cleaning member 1, the blocking portion 212 can also prevent the user's hand from sliding forward from the sleeve 211, thereby improving the stability during use.

[0078] Optionally, the first through hole 215 penetrates the sleeve 211 and the blocking portion 212, and the limiting portion 213 is formed as an annular boss 216 with an elliptical hollow region arranged on the inner wall of the first through hole 215 of the blocking portion 212. The annular boss 216 is arranged on the inner wall of the first through hole 215 of the blocking portion 212, so that after the driving assembly 21 is sleeved on the connecting rod 22, it can be in contact with the spiral groove 214, thereby maximizing the effective driving distance of the forward movement of the driving assembly 21 when driving the connecting rod 22 to rotate.

[0079] Optionally, the toilet brush further comprises a handle 3, which is arranged at the end of the connecting rod 22 away from the cleaning element 1; the connecting rod 22 rotates relative to the handle 3 when being driven to rotate by the driving assembly 21. The handle 3 is used for the user to hold, and meanwhile, the handle 3 can rotate relative to the connecting rod 22, which reduces the influence of the handle 3 on the rotation of the rotating element during rotation and improves the convenience of use for the user.

[0080] Optionally, the handle 3 has an inner cavity with an open end, and the end of the connecting rod 22 extends into the inner cavity and is connected with the inner wall of the inner cavity. The connecting rod 22 is connected with the inner wall of the inner cavity of the handle 3, without the need to arrange an additional structural element on the outside of the handle 3, and the inner cavity is hollow, which can effectively reduce the use of materials and reduce the production cost.

[0081] Optionally, the inner wall of the inner cavity of the handle 3 is provided with a first supporting 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 supporting portion 31 to limit the end of the connecting rod 22 from being separated from the inner cavity of the handle 3.

[0082] It should be noted that the first supporting portion 31 can be a protrusion protruding from the inner wall of the inner cavity, which can be annular or spaced apart along the same plane. The first protrusion 41 can also be a groove on the inner wall, and the groove has a bottom wall facing the end of the connecting rod 22; the first limiting portion 213 can cooperate with the bottom wall of the groove to limit the end of the connecting rod 22 from being separated from the inner cavity of the handle 3.

[0083] Optionally, the first supporting portion 31 is formed as an annular boss 216 of the inner wall of the inner 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 with the first supporting portion 31 after passing through the annular boss 216, and will not fall off due to the presence of other gaps, thereby effectively improving the reliability of assembly.

[0084] Optionally, the first limiting portion 213 is formed as at least two elastic arms 2211 arranged at the end of the connecting rod 22, and the outer side of the elastic arm 2211 is provided with a clamping boss 2212; when the end of the connecting rod 22 extends into the inner cavity, the clamping boss 2212 is clamped with the annular boss 216. When the connecting rod 22 is assembled with the handle 3, the elastic arm 2211 can be contracted under force so that the connecting rod 22 passes through the annular boss 216, and then the elastic arm 2211 restores to the original state under the action of elastic restoring force, which can effectively improve the assembly efficiency of the connecting rod 22 and the handle 3.

[0085] Optionally, the outer wall of the connecting rod 22 is provided with a second limiting portion 213, when the end of the connecting rod 22 extends into the inner cavity, the end of the handle 3 abuts against the second limiting portion 213 to limit the maximum displacement of the end of the connecting rod 22 extending into the inner cavity. The second limiting portion 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 driving assembly 21, so that the assembly efficiency is effectively improved, and the sliding of the connecting rod 22 along the inner cavity of the handle 3 is prevented.

[0086] Optionally, the second limiting portion 213 is an annular step provided on the outer wall of the connecting rod 22. The annular step makes the connecting rod 22 abut against the lower end surface of the handle, preventing the connecting rod 22 from moving in the inner cavity.

[0087] Optionally, the connecting rod 22 is provided with a hollow cavity, the inner wall of the hollow cavity is provided with a limiting portion 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 portion 213 slides along the spiral groove 214, so that the connecting rod 22 rotates.

[0088] The first transmission cooperation mode is used in the following working process:

[0089] In use, the user holds the cleaning piece 1 of the toilet brush downward, holds the handle 3 with one hand, and holds the sleeve 211 with the other hand, and pushes the sleeve 211 forward, at this time, the hand holding the sleeve 211 can be selected to abut against the resisting portion 212. The limiting portion 213 in the sleeve 211 or the first through hole 215 cooperates with the spiral groove 214 on the connecting rod 22, so that the connecting rod 22 rotates, and in turn drives the cleaning piece 1 to rotate to clean the inner wall of the cavity to be cleaned.

[0090] Referring to Figures 8-10 , the second transmission cooperation mode is implemented as follows:

[0091] As shown in Figure 8 , the connecting rod 22 is provided with a hollow cavity, the inner wall of the hollow cavity is provided with a limiting portion 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 portion 213 slides along the spiral groove 214, so that the connecting rod 22 rotates. When the driving assembly 21 moves along the length direction of the connecting rod 22, the limiting portion 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 smaller, the rotation of the connecting rod 22 is more convenient, and the rotation efficiency of the cleaning piece 1 is higher.

[0092] Optionally, as shown in Figure 8 , Figure 9As shown, the limiting part 213 is a ball arranged on the inner wall of the hollow cavity away from the cleaning member 1. When the driving assembly 21 extends into the hollow cavity and moves along the axial direction of the connecting rod 22, the ball can slide along the spiral groove 214, so that the connecting rod 22 rotates, and since the ball itself can also rotate, the rotation efficiency of the connecting rod 22 can be better enhanced, and the rotation resistance can be reduced.

[0093] Optionally, the inner wall of the end of the hollow cavity away from the cleaning member 1 is provided with a semispherical groove, the ball is arranged in the semispherical groove and protrudes from the inner wall of the hollow cavity. The semispherical groove can limit the ball and also can make the ball partially exposed to cooperate with the driving assembly 21 to rotate.

[0094] Optionally, the toilet brush further comprises a limiting sleeve 5, the limiting sleeve 5 is sleeved on the outer periphery of the connecting rod 22, and one end of the limiting sleeve 5 is connected with the connecting rod 22, and the other end of the limiting sleeve 5 is provided with an opening so that the cleaning member 1 extends out of the opening;

[0095] Further, as shown, Figure 11 the limiting sleeve 5 is used to rotate relative to the connecting rod 22 when the connecting rod 22 rotates under the driving of the driving assembly 21, and the end of the opening abuts against the edge of the cavity to be cleaned when the cleaning member 1 extends into 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 not only support the toilet brush, but also prevent the cleaning member 1 from being inserted too deep into the inner wall of the cavity to be cleaned so as to be not easy to pull out.

[0096] Optionally, the top end of the limiting sleeve 5 is provided with a second supporting part 32, one end of the connecting rod 22 is provided with a second limiting part 213, the limiting sleeve 5 is connected with the outer periphery of the connecting rod 22 through the second supporting part 32 and the second limiting part 213, and the second supporting part 32 and the second limiting part 213 can rotate relative to each other. The second supporting part 32 and the second limiting part 213 cooperate to prevent the cleaning member 1 from being inserted too deep into the inner wall of the cavity to be cleaned so as to be not easy to pull out.

[0097] Optionally, a reset member 6 is arranged between the connecting rod 22 and the driving assembly 21, and the reset member 6 is used to reset the driving assembly 21 after the driving assembly 21 extends into the hollow cavity and moves along the axial direction of the connecting rod 22. When the use of the toilet brush to clean the inner cavity of the object to be cleaned is finished, the driving assembly 21 is automatically reset through the reset member 6, the operation steps of the user are reduced, and the user experience is improved.

[0098] Optionally, the reset member 6 is an elastic member arranged 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 of the elastic member abuts against the end of the driving assembly 21 extending into the hollow cavity. The elastic member is used to store energy when the hollow cavity moves along the axial direction of the connecting rod 22, and to apply force to the driving assembly 21 to reset the driving assembly 21 when the force is released.

[0099] Optionally, the driving assembly 21 comprises a column and a handle arranged at one end of the column away from the cleaning piece 1, a helical groove 214 is arranged 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 helical groove 214, so that the connecting rod 22 rotates.

[0100] The second transmission cooperation mode works as follows during use:

[0101] During use, the user holds the handle and pushes it downward, so that the column is inserted into the middle of the connecting rod 22, and the helical groove 214 on the column cooperates with the ball on the connecting rod 22 to slide, so that the connecting rod 22 rotates, and in turn drives the cleaning piece 1 to rotate to clean the inner wall of the cavity to be cleaned.

[0102] Optionally, a locking structure is arranged between the connecting rod 22 and the driving assembly 21, and the locking structure is used to lock the driving assembly 21 on the connecting rod 22 when the driving assembly 21 moves along the axial direction of the connecting rod 22 to the end away from the cleaning piece 1.
