Description

Technical Field

[0001] The utility model belongs to the technical field of motor auxiliary protection structures, and particularly relates to an intelligent toilet motor protection cover. Background Art

[0002] At the present stage, intelligent toilets have entered thousands of households. More and more people choose to use intelligent toilets for the convenience of going to the toilet. The intelligent devices of intelligent toilets generally achieve their intelligent operations through automatic lid opening and automatic spraying. Therefore, in order to perform automatic flipping and automatic telescoping, generally a stepping motor is installed inside, and the rotation of the driving shaft is realized by the driving of the motor to drive flipping and telescoping. However, at present, the commercially available stepping motors are basically fixed by snap-fastening, and the structure is relatively unstable. After long-term operation, it is very likely to fall off, resulting in incomplete meshing of the gear set inside, and thus being stuck and unable to operate. This is also the current situation faced by most intelligent toilets nowadays. The repair of the stepping motor is the key point of the intelligent toilet repair. Once the stepping motor stops working, it will cause the toilet lid unable to open and the spray head unable to automatically telescope, seriously affecting the user experience. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides an intelligent toilet motor protection cover. By inserting the wiring terminal into the card seat, pressing the wiring terminal by the bottom layer cover, and partitioning the inner cavity of the outer shell, the internal space of the stepping motor is partitioned. Then, the top layer cover presses the bottom layer cover, and is locked from the side of the outer shell by screws. The protection cover composed of the bottom layer cover and the top layer cover can effectively protect the motor inside the stepping motor, ensuring that there will be no falling or loosening.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is:

[0005] An intelligent toilet motor protection cover includes an outer shell, a wiring terminal, a bottom layer cover and a top layer cover. The outer shell is a cylindrical structure with an upward opening and an assembly cavity inside. A card seat with a side opening is provided on the side wall of the outer shell. The card cavity in the card seat is communicated with the assembly cavity. The wiring terminal is fitted in the card cavity. A clamping plate is provided in the card seat. A clamping groove cooperating with the clamping plate is provided on the wiring terminal. The wiring terminal is inserted into the card cavity from top to bottom through the cooperation of the clamping groove and the clamping plate. The upper end surface of the wiring terminal is flush with the upper end surface of the clamping plate. A limiting seat pointing towards the assembly cavity is provided at the top of the inner side opening of the card seat. The limiting seat is a stepped structure that gradually expands from bottom to top. A first clamping seat and a second clamping seat are provided in the limiting seat. One end of the bottom layer cover is inserted into the card seat, and the other end is inserted into the assembly cavity. The bottom layer cover divides the assembly cavity into a gear cavity at the upper end and a motor cavity at the lower end. The top layer cover covers the upper end of the bottom layer cover.

[0006] One end of the bottom cover is provided with an L-shaped pressing plate. The short plate of the pressing plate is inserted into the limiting seat and abuts against the first clamping seat. The lower end surface of the short plate of the pressing plate abuts against the upper end surface of the wiring terminal. The outer side wall of the long plate of the pressing plate abuts against the clamping plate. The other end of the bottom cover is provided with a supporting seat extending upwards. One end of the top cover is inserted into the second clamping seat in the limiting seat and its bottom abuts against the upper end surface of the short plate of the pressing plate. The other end of the top cover is provided with a fixing plate extending downwards. The fixing plate is inserted into the space between the supporting seat and the inner side wall of the housing. The upper end surface of the supporting seat abuts against the lower end surface of the top cover. The supporting seat is provided with a limiting post, and the fixing plate is provided with a limiting groove. The limiting post and the limiting groove cooperate with each other.

[0007] For the intelligent toilet motor protection cover adopting this structure, the assembly cavity in the housing is used to install the motor and the gear set. In order to be able to conduct wiring, a clamping seat opening towards the side is provided on the side wall of the housing. The wiring terminal is inserted into the clamping cavity from top to bottom. The wiring terminal is fixed through the cooperation of the clamping plate and the clamping groove, and after the wiring terminal is inserted to the bottom, the upper end surface of the wiring terminal is kept flush with the upper end surface of the clamping plate. An L-shaped pressing plate is provided at one end of the bottom cover. The short plate of the pressing plate is inserted into the first clamping seat in the limiting seat at the upper end of the clamping seat. After the pressing plate is pressed downwards, it will downwardly abut against the upper end surface of the wiring terminal, and the bottom cover is horizontally placed in the assembly cavity, dividing the assembly cavity into an upper gear cavity and a lower motor cavity. The supporting seat extending upwards at the other end of the bottom cover is used to provide a supporting force for the top cover covering the upper opening of the gear cavity. Therefore, one end of the top cover is inserted into the second clamping seat in the limiting seat, and the other end of the top cover is pressed downwards until it abuts against the supporting seat. Therefore, the protection cover formed by the bottom cover can, on the one hand, press down the wiring terminal, and on the other hand, divide the assembly cavity into a gear cavity and a motor cavity for the assembly of the gear set and the motor. And for the bottom cover with one end kept pressed, the other end can also maintain a relatively stable state due to its rigidity. Therefore, the supporting seat can provide an upward supporting force. When the top cover presses down the bottom cover, this layer of protection cover of the top cover can also provide a downward pressing force for the bottom cover, thus realizing the function of double-layer pressing. In order to ensure that the top cover and the bottom cover can be connected to each other, a fixing plate is provided at the bottom of the top cover. Through the cooperation of the limiting groove on it and the limiting post on the supporting seat, clamping is carried out, so as to realize the mutual buckling of the top cover and the bottom cover. The fixed and supported fixing plate can realize a firm connection, ensuring that the protection cover will not fall off.

[0008] Furthermore, a through hole is provided on the outer side wall of the housing, a perforation is provided on the fixing plate, and a screw hole is provided on the supporting seat. The central axes of the through hole, the perforation and the screw hole coincide.

[0009] Compared with the prior art, the advantages of the present utility model are as follows: The short board of the L-shaped pressing plate at one end of the bottom layer cover is inserted into the first card seat in the limit seat to realize the downward pressing of the wiring terminal, and the assembly cavity is divided into a gear cavity and a motor cavity which are convenient for the assembly of the gear set and the motor. The other end of the bottom layer cover provides a supporting force for the top layer cover that is closed by the upper end cover. Therefore, after one end of the top layer cover is inserted into the second card seat, the other end is pressed downward to completely cover the gear cavity, realizing the function of double-layer pressing. The limit groove on the fixing plate at one end of the top layer cover is cooperatively clamped with the limit post on the supporting seat. After being completely pressed, only by removing the top layer cover first can the bottom layer cover be removed. The firm insertion is carried out in the form of the structure to avoid the possibility of falling off. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] One end of the bottom cover 3 is provided with an L-shaped pressing plate 31. The short plate 311 of the pressing plate 31 is inserted into the limiting seat 123 and abuts against the first clamping seat 1231.

A limiting post 321 is provided on the supporting seat 32, and a limiting groove 411 is provided on the fixing plate 41. The limiting post 321 cooperates with the limiting groove 411.

[0021] Furthermore, through holes are provided on the outer side wall of the housing 1, perforations 412 are provided on the fixing plate 41, and screw holes 322 are provided on the support base 32. The central axes of the through holes, the perforations 412, and the screw holes 322 coincide with each other.

[0022] Description of the working mode of the present utility model:

[0023] For the intelligent toilet motor protection cover adopting this structure, the assembly cavity 11 inside the housing 1 is used to install the motor and the gear set. In order to conduct wiring, a clamping seat 12 with a side opening is provided on the side wall of the housing 1. The wiring terminal 2 is inserted into the clamping cavity 121 from top to bottom. The wiring terminal 2 is fixed through the cooperation of the clamping plate 122 and the clamping groove 21. After the wiring terminal 2 is inserted to the bottom, the upper end surface of the wiring terminal 2 is kept flush with the upper end surface of the clamping plate 122. And an L-shaped pressing plate 31 is provided at one end of the bottom cover 3. The short plate 311 of the pressing plate 31 is inserted into the first clamping seat 1231 in the upper limit seat 123 of the clamping seat 12. After the pressing plate 31 is pressed down, it will downwardly abut against the upper end surface of the wiring terminal 2. And the bottom cover 3 is horizontally placed in the assembly cavity 11, dividing the assembly cavity 11 into an upper gear cavity 111 and a lower motor cavity 112. The support base 32 extending upward at the other end of the bottom cover 3 is used to provide a supporting force for the top cover 4 covering the upper opening of the gear cavity 111. Therefore, the second clamping seat 1232 at one end of the top cover 4 is inserted into the limit seat 123, and the other end of the top cover 4 is pressed down until it abuts against the support base 32. Therefore, on the one hand, the protection cover formed by the bottom cover 3 can downwardly press and hold the wiring terminal 2, and on the other hand, it can divide the assembly cavity 11 into a gear cavity 111 and a motor cavity 112 for the assembly of the gear set and the motor. And for the bottom cover 3 with one end kept pressed, the other end can also maintain a relatively stable state due to rigidity. Therefore, the support base 32 can provide an upward supporting force. When the top cover 4 presses the bottom cover 3 downward, this layer of protection cover of the top cover 4 can also provide a downward pressing force for the bottom cover 3, thus realizing the function of double-layer pressing. In order to ensure that the top cover 4 and the bottom cover 3 can be connected to each other, a fixing plate 41 is provided at the bottom of the top cover 4. Through the cooperation of the limiting groove 411 thereon and the limiting post 321 on the support base 32, clamping is carried out, so as to realize the mutual buckling of the top cover 4 and the bottom cover 3. The fixing plate 41 and the support base 32 that are pressed and fixed can achieve a stable connection, ensuring that the protection cover will not fall off. In order to achieve further fixation, through holes are provided on the housing 1, perforations 412 are provided on the fixing plate 41, and screw holes 322 are provided on the support base 32. The central axes of the through holes, the perforations 412, and the screw holes 322 coincide with each other. Therefore, taking a screw and passing it through the through hole and the perforation 412 in sequence and then screwing it into the screw hole 322 can connect the housing 1, the fixing plate 41, and the support base 32 to each other, and a better fixing effect can be achieved.

[0024] The beneficial effects of the present utility model are as follows: The short board 311 of the L-shaped pressing plate 31 at one end of the bottom layer cover 3 is inserted into the first clamping seat 1231 in the limit seat 123 to realize the downward pressing of the wiring terminal 2, and the assembly cavity 11 is divided into a gear cavity 111 and a motor cavity 112 that are convenient for the assembly of the gear set and the motor. The other end of the bottom layer cover 3 provides a supporting force for the top layer cover 4 that closes the upper end cover. Therefore, after one end of the top layer cover 4 is inserted into the second clamping seat 1232, the other end is pressed down to completely cover the gear cavity 111, realizing the function of double-layer pressing. The limit groove 411 on the fixing plate 41 at one end of the top layer cover 4 is matched and clamped with the limit post 321 on the supporting seat 32. After being completely pressed, only by removing the top layer cover 4 first can the bottom layer cover 3 be removed. The stable insertion is achieved through the structure to avoid the possibility of falling off. Then, by using screws to connect the housing 1, the fixing plate 41, and the supporting seat 32 to each other, a better fixing effect can be achieved.
