Description

Technical Field

[0001] This utility model relates to the technical field of intelligent toilet toilet cover equipment, specifically to a simple replacement structure for toilet toilet covers. Background Technology

[0002] In the field of automatic sanitary roll changing technology, the film roll is fitted around the outer circumference of a rotating shaft. The shaft is driven by a motor to rotate, enabling automatic changing and conveying of the sanitary roll. A connecting wheel is used to transmit and connect the motor output shaft and the rotating shaft to ensure that the motor's driving force is stably transmitted to the rotating shaft, guaranteeing a smooth roll changing process. However, most existing adapter wheels are fixed designs. When changing sanitary roll sleeves, the shaft with the old roll sleeve must first be removed from the motor output shaft, and then the shaft with the new film roll must be installed back onto the motor output shaft. Because the fixed adapter wheel is in a fixed position, the shaft must be precisely aligned with the axis of the motor output shaft when reinstalling it; otherwise, effective assembly cannot be completed. This precise alignment requirement significantly increases the operational difficulty, not only prolonging the roll sleeve replacement operation time but also easily leading to improper assembly due to alignment deviations, affecting the normal operation of subsequent devices. Utility Model Content In view of the shortcomings of the existing technology, the purpose of this utility model is to propose a simple replacement structure for toilet toilet cover to solve the problems mentioned in the background section above.

[0003] This utility model is achieved through the following technical solution: A simple replacement structure for a toilet toilet seat cover includes a motor and a rotating shaft. The output shaft of the motor is detachably connected to an adapter wheel, which can selectively move between a first position and a second position. The outer wall of the adapter wheel is provided with a first stop, and the rotating shaft is provided with a second stop. When the adapter wheel is in the first position, the first stop and the second stop engage with each other, thereby causing the output shaft to drive the rotating shaft to rotate. When the adapter wheel is in the second position, the first stop and the second stop disengage from each other, thereby making the rotating shaft and the adapter wheel detachable. A spring is provided between the output shaft and the adapter wheel. The adapter wheel is kept in a first position by the spring, and the adapter wheel is switched from the first position to a second position by compressing the spring. It also includes a support base, and the rotating shaft has a snap-fit ​​post at the end away from the motor, and the support base has a snap-fit ​​groove for the snap-fit ​​post to be inserted.

[0004] Furthermore, one end of the snap-fit ​​groove is connected to the outside to form an opening, and the snap-fit ​​post is inserted into the snap-fit ​​groove along the opening.

[0005] Furthermore, the support base is provided with two spaced-apart snap-fit ​​plates. Each snap-fit ​​plate has a protruding anti-detachment part facing the adjacent side. A hollow groove is provided at the back end of the anti-detachment part. The snap-fit ​​groove is formed at the rear end of the anti-detachment part. The snap-fit ​​part restricts the snap-fit ​​post from detaching from the snap-fit ​​groove.

[0006] Furthermore, it also includes a retainer sleeved on the outer periphery of the output shaft, the retainer having two deformable hooks, the adapter wheel having a slot for the deformable hooks to be inserted into, and the deformable hooks engaging with the side end face of the adapter wheel.

[0007] Furthermore, the outer circumference of the adapter wheel is provided with a plurality of protrusions arranged in a circumferential array, the protrusions constituting the first stop portion, and the rotating shaft is provided with a notch portion for the protrusions to be inserted, the notch portion constituting the second stop portion.

[0008] Furthermore, the adapter wheel is provided with a relief groove for the spring portion to be embedded in, and the adapter wheel has a positioning boss in the relief groove for embedding the spring.

[0009] Furthermore, the rotating shaft includes two spaced-apart baffle portions.

[0010] Furthermore, both the snap-fit ​​groove and the snap-fit ​​post have circular cross-sections.

[0011] The beneficial effects of this utility model are as follows: A simple replacement structure for a toilet seat cover includes a motor and a rotating shaft. The output shaft of the motor is detachably connected to an adapter wheel, which selectively moves between a first position and a second position. The outer wall of the adapter wheel is provided with a first stop, and the rotating shaft is provided with a second stop. When the adapter wheel is in the first position, the first and second stops engage with each other, thereby causing the output shaft to drive the rotating shaft to rotate. When the adapter wheel is in the second position, the first and second stops disengage, thereby making the rotating shaft and the adapter wheel detachable. A spring is provided between the output shaft and the adapter wheel, which keeps the adapter wheel in the first position. By compressing the spring, the adapter wheel switches from the first position to the second position. The structure also includes a support base. The rotating shaft has a snap-fit ​​post at the end away from the motor, and the support base has a snap-fit ​​groove for the snap-fit ​​post to be inserted. Because the adapter wheel and the output shaft are detachable and non-rigidly connected, the load concentration problem caused by rigid connections is avoided. On the one hand, it can prevent the film sleeved on the outer circumference of the rotating shaft from getting stuck due to vibration, ensuring the smoothness of the roll conveyor; on the other hand, it can avoid the impact load from acting directly on the counting wheel, reducing the risk of the counting wheel breaking and being damaged, ensuring the stability of the counting function, and extending the service life of the components.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] Reference Figures 1 to 4 As shown, a simple replacement structure for a toilet toilet seat cover includes a motor 1 and a rotating shaft 2. The output shaft 11 of the motor 1 is detachably connected to an adapter wheel 3, which can selectively move between a first position and a second position. The outer wall of the adapter wheel 3 is provided with a first stop 31, and the rotating shaft 2 is provided with a second stop 21. When the adapter wheel 3 is in the first position, the first stop part 31 and the second stop part 21 engage with each other, thereby causing the output shaft 11 to drive the rotating shaft 2 to rotate. When the adapter wheel 3 is in the second position, the first stop part 31 and the second stop part 21 disengage from each other, thereby making the rotating shaft 2 detachable from the adapter wheel 3; A spring 4 is provided between the output shaft 11 and the adapter wheel 3. The adapter wheel 3 is kept in a first position by the spring 4, and the adapter wheel 3 is switched from the first position to a second position by compressing the spring 4. It also includes a support base 5, and the rotating shaft 2 has a snap-fit ​​post 22 at the end away from the motor 1. The support base 5 has a snap-fit ​​groove 51 for the snap-fit ​​post 22 to be inserted.

[0018] During assembly, by inserting the second stop 21 of the rotating shaft 2 into the first stop 31 of the adapter wheel 3, the adapter wheel 3 is automatically displaced a certain distance toward the motor 1 by the compression spring 4, so that the locking post 22 can be directly pressed into the locking groove 51; during disassembly, simply apply a displacement action to the rotating shaft 2 toward the adapter wheel 3 to remove the rotating shaft 2 from the motor 1 and the support base 5, making assembly and disassembly operations convenient.

[0019] During operation, the first stop 31 and the second stop 21 are engaged with each other under the action of the spring 4, and the output shaft 11 of the motor 1 will drive the rotating shaft 2 to rotate, thus completing the film feeding action.

[0020] One end of the snap-fit ​​groove 51 is connected to the outside to form an opening, and the snap-fit ​​post 22 is inserted into the snap-fit ​​groove 51 through the opening. This opening structure provides a clear guiding path for the assembly of the snap-fit ​​post 22 and the snap-fit ​​groove 51, so that the snap-fit ​​post 22 can be smoothly inserted through the opening without precise alignment with the entire snap-fit ​​groove 51, which greatly reduces the alignment difficulty during assembly, simplifies the operation process, and helps to improve assembly efficiency.

[0021] Because the adapter wheel 3 and the output shaft 11 are detachable and non-rigidly connected, the load concentration problem caused by rigid connections is avoided. On the one hand, this prevents the film sleeved on the outer periphery of the rotating shaft 2 from getting stuck due to vibration, ensuring the smoothness of the roll conveyor; on the other hand, it avoids impact loads acting directly on the counting wheel, reducing the risk of the counting wheel breaking and being damaged, ensuring stable counting function, and extending the service life of the components.

[0022] Preferably, both the snap-fit ​​groove 51 and the snap-fit ​​post 22 have circular cross-sections, which can effectively prevent jumping during rotation. The support base 5 is provided with two spaced-apart snap-fit ​​plates 52. Each snap-fit ​​plate 52 has a protruding anti-detachment part 53 facing the adjacent side. A hollow groove 54 is provided at the back end of the anti-detachment part 53. The snap-fit ​​groove 51 is formed at the rear end of the anti-detachment part 53. The snap-fit ​​post 22 is restricted from detaching from the snap-fit ​​groove 51 by the anti-detachment part 53.

[0023] During the process of inserting the snap-fit ​​post 22 into the snap-fit ​​groove 51 along the opening, the presence of the hollow groove 54 makes it easy for the anti-detachment part 53 to deform and avoid the snap-fit ​​post 22. After the snap-fit ​​post 22 is inserted into the snap-fit ​​groove 51, the anti-detachment part 53 locks it in place at the side end of the snap-fit ​​post 22, thereby preventing the snap-fit ​​post 22 from detaching from the snap-fit ​​groove 51.

[0024] Furthermore, it also includes a retainer 6 sleeved on the outer periphery of the output shaft 11. The retainer 6 is provided with two deformable hooks 61. The adapter wheel 3 is provided with a slot 32 for the deformable hooks 61 to be inserted. The deformable hooks 61 are fastened to the side end face of the adapter wheel 3.

[0025] By utilizing the elastic deformation characteristics of the deformation hooks 61 through the card holder 6, during assembly, it is only necessary to put the card holder 6 onto the output shaft 11, then align the deformation hooks 61 with the slots 32 of the adapter wheel 3 and apply appropriate pressure to achieve quick engagement between the hooks and the slots 32. The two deformation hooks 61 are symmetrically arranged and engaged on the side end face of the adapter wheel 3, which can form a stable limit and fixation on the adapter wheel 3 from both sides, ensuring the coaxiality between the adapter wheel 3 and the output shaft 11, and reducing the offset or shaking of the adapter wheel 3 during operation.

[0026] The deformable hook 61 possesses a certain degree of elastic deformation capability, forming a flexible connection structure with the side end face of the adapter wheel 3, rather than a traditional rigid contact. When the motor 1 drives the output shaft 11 to rotate the adapter wheel 3, the elastic deformation can effectively buffer the impact and vibration between the two, avoiding the load concentration problem caused by the rigid connection. On the one hand, it can prevent the film sleeved on the outer periphery of the rotating shaft 2 from getting stuck due to vibration, ensuring the smoothness of the roll conveying; on the other hand, it can avoid the impact load from acting directly on the counting wheel, reducing the risk of the counting wheel breaking and being damaged, ensuring the stability of the counting function, and extending the service life of the components.

[0027] Furthermore, the outer periphery of the adapter wheel 3 is provided with a plurality of protrusions arranged in a circumferential array, which constitute the first stop portion 31, and the rotating shaft 2 is provided with a notch for the protrusions to be inserted, which constitutes the second stop portion 21.

[0028] The protrusions and notches of the circumferential array form a precise fitting structure, which can effectively increase the torque transmission area between the adapter wheel 3 and the shaft 2.

[0029] The corresponding fitting structure of the protrusion and the notch has a natural positioning and guiding function. When assembling the adapter wheel 3 and the shaft 2, the operator does not need to repeatedly adjust the relative angle between the two. He only needs to align the protrusion of the adapter wheel 3 with the notch of the shaft 2 and insert it to quickly complete the coaxial positioning and connection of the two, which greatly reduces the difficulty of aligning the angle during assembly.

[0030] The adapter wheel 3 is provided with a relief groove 33 for the spring 4 to be partially embedded in. The adapter wheel 3 has a positioning boss 34 embedded in the relief groove 33 for the spring 4 to be embedded in. The positioning boss 34 is embedded inside the spring 4, and the relief groove 33 covers the outer periphery of the spring 4, ensuring that the spring 4 always moves stably in a preset direction, providing reliable elastic support for the cooperation between the adapter wheel 3 and related components.

[0031] The rotating shaft 2 includes two spaced baffle portions 23. The two baffle portions 23 are located on both sides of the axial direction of the film roll sleeve, forming a limiting range adapted to the width of the roll sleeve. They can directly block the lateral movement of the roll sleeve from both ends. Both baffle portions 23 can effectively limit the film roll sleeve from shifting along the axial direction of the rotating shaft 2, avoiding the problem of the roll sleeve slipping on one side and stacking on the other side.
