Description
Technical Field
[0001] The utility model belongs to the technical field of toilet motors, and particularly relates to a connection structure of an intelligent toilet motor. Background Technique
[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 therein, and the rotation of the rotating shaft is driven by the motor to achieve driving flipping and telescoping. Therefore, the stress concentrated on the driving rod used to be driven to rotate to drive the lid flipping and telescoping is the most concentrated, and the most severely damaged part is also this accessory. Therefore, when an intelligent toilet is damaged, generally problems occur at this position. However, when replacing, since the stepping motor is basically an integral structure device, it needs to be disassembled as a whole for replacement. In fact, only small accessories such as the driving rod and the driving teeth connected thereto are damaged, and the gear set and the motor therein are intact. Disassembling and discarding it as a whole will increase the maintenance cost. Content of the Utility Model
[0003] To solve the above technical problems, the utility model provides a connection structure of an intelligent toilet motor. By taking the driving rod and the driving teeth as detachable components, they are installed and disassembled from the matching column, and the continuous pressing force of the driving rod is maintained by the pressing head. When ensuring normal operation, disassembly, repair and replacement can be carried out conveniently, and the maintenance cost of the equipment can be reduced.
[0004] To achieve the above object, the technical solution adopted by the utility model is:
[0005] An intelligent toilet motor connection structure, comprising a housing assembly, a driving assembly and a pressing assembly. The housing assembly includes a housing, a partition plate and a cover plate. The partition plate is horizontally disposed in the housing and divides the inner cavity of the housing into a gear cavity and a motor cavity. The cover plate covers the upper opening of the housing. The driving assembly includes a driving rod, a driving gear, a gear set and a motor. The motor is disposed in the motor cavity, and the gear set is disposed in the gear cavity. The driving rod passes through the through hole on the partition plate from bottom to top and extends into the gear cavity and out of the cover plate. The output end of the motor is engaged with the driving gear connected to the driving rod through the gear set. The pressing assembly abuts against the bottom of the driving rod through the fitting hole at the bottom of the housing. A fitting column with a hollow interior is provided in the motor cavity. The lower end surface of the fitting column is fitted on the fitting hole, and the upper end surface of the fitting column abuts against the lower end surface of the partition plate. The inner cavity diameter of the fitting column is the same as the diameter of the fitting hole. An internal thread is provided in the inner cavity of the fitting column. The pressing assembly includes a pressing head and a spring. An external thread is provided on the outer side wall of the pressing head. The upper end surface of the pressing head abuts against the bottom of the driving rod. A screw groove is provided on the lower end surface of the pressing head. The external thread is matched with the internal thread. The spring is sleeved on the driving rod. The upper end surface of the spring abuts against the lower end surface of the driving gear, and the lower end surface of the spring abuts against the upper end surface of the pressing head.
[0006] For the intelligent toilet motor connection structure adopting this structure, the housing, the partition plate and the cover plate included in the housing assembly are combined into an integral body. The partition plate divides the inner cavity of the housing into a gear cavity and a motor cavity, aiming to separate the gear set and the motor. In order to realize the basic operation function of the toilet motor, a driving rod is needed to drive the external gear for action transmission. Therefore, the driving rod passes through the through hole on the partition plate from bottom to top and enters the gear cavity and out of the cover plate. A flat head is provided on the exposed part outside the cover plate for external plugging. An outwardly extending first convex edge and a second convex edge are provided on the outer side wall of the driving rod. The first convex edge abuts against the inner side surface of the cover plate to prevent the flat head on the driving rod from protruding outwards excessively. The upper end surface of the driving gear abuts against the second convex edge. Therefore, the positions of the driving rod and the driving gear in the housing are relatively fixed and both are kept rotating at a specific position through the limitation of the first convex edge and the second convex edge. In order to drive the driving rod to rotate, the power is transmitted through the setting of the motor and the gear set. The motor is disposed in the motor cavity, and the output end of the motor drives the gear set for transmission. During the assembly process of the driving gear, the teeth on it will be engaged with the teeth on the gear set, so that the transmission force received by the gear set will be transmitted to the driving gear. The connection form between the driving gear and the driving rod can be key connection or connection by a limiting clamping column to ensure that the driving rod and the driving gear follow each other. Therefore, when the motor is started, the driving rod can be driven to rotate, which is the most basic connection structure form.
[0007] In order to set the driving rod in a detachable form, a mating hole is provided at the bottom of the housing, and a hollow mating column is additionally provided in the mating hole. The upper end surface of the mating column abuts against the lower end surface of the partition plate, providing support force for the partition plate. At the same time, the hollow inner cavity of the mating column facilitates the assembly of the driving rod. During assembly, first insert the driving rod so that the flat head of the driving rod extends outside the cover plate, and then assemble the driving gear on the driving rod until the teeth on the driving gear mesh with the gear set. The external thread on the pressing head is matched with the internal thread in the inner cavity of the mating column. After the pressing head is screwed in, its top surface abuts against the bottom of the driving rod, and the upper end of the spring sleeved outside the driving rod abuts against the lower end surface of the driving gear, and the lower end abuts against the upper end surface of the pressing head. Therefore, when the pressing head is screwed into the mating column through the screw groove, the pressing force of the spring on the driving gear can be increased to ensure that the driving gear meshes with the gear set. When the driving rod is subjected to excessive external force, it will force the driving gear to compress in the direction of the spring, which can protect the driving gear from tooth breakage, and by adjusting the spring, the pressing force of the driving gear can be changed.
[0008] Further, a rotating column is provided at the bottom of the driving rod, a rotating groove is provided on the upper end surface of the pressing head, and lubricating grooves are provided on the inner side wall of the rotating groove. The rotating column is fitted in the rotating groove.
[0009] Compared with the prior art, the advantages of the present utility model are as follows: Through the connection between the driving rod and the driving gear, the driving force is provided by the motor-driven gear set to ensure that the transmission power formed by this connection method can play the most basic transmission role. In order to facilitate the disassembly and replacement of parts, a pressing head is provided. By squeezing the spring, the pressing force of the driving gear on the gear set is generated. When the driving rod is subjected to excessive external force, it will force the driving gear to compress in the direction of the spring, which can protect the driving gear from tooth breakage, and by adjusting the spring, the pressing force of the driving gear can be changed.

[0020] The working mode of the present utility model is described as follows:
[0021] The intelligent toilet motor connection structure adopts this structure. The shell 11, partition 12 and cover plate 13 included in the shell assembly 1 are combined into a whole. The partition 12 divides the inner cavity of the shell 11 into a gear cavity 14 and a motor 24 cavity 15. The purpose is to separate the gear set 23 and the motor 24. In order to realize the basic operation of the toilet motor 24, a driving rod 21 is required to drive the external gear to perform action transmission. Therefore, the driving rod 21 passes through the through hole 121 on the partition 12 from bottom to top into the gear cavity 14 and passes through the cover plate 13. A flat head is provided on the exposed part outside the cover plate 13 for external plug-in. The outer side wall of the driving rod 21 is provided with a first convex edge and a second convex edge extending outward. The first convex edge abuts against the inner side surface of the cover plate 13 to prevent the flat head on the driving rod 21 from extending excessively outward, and the upper end surface of the driving tooth 22 is Abutting on the second convex edge, the positions of the driving rod 21 and the driving tooth 22 in the shell 11 are relatively fixed, and are kept in a specific position for rotation by the restrictions of the first convex edge and the second convex edge. In order to drive the driving rod 21 to rotate, the power is transmitted by the setting of the motor 24 and the gear set 23. The motor 24 is set in the motor 24 cavity 15, and the output end of the motor 24 drives the gear set 22 for transmission. During the assembly process of the driving tooth 22, the teeth on the driving tooth 22 will mesh with the teeth on the gear set 23, so that the transmission force received by the gear set 23 will be transmitted to the driving tooth 22. The connection form of the driving tooth 22 and the driving rod 21 can be a key connection or a limit column connection to ensure that the driving rod 21 and the driving tooth 22 move with each other. Therefore, when the motor 24 is started, the driving rod 21 can be driven to rotate, which is the most basic connection structure.
[0022] In order to make the drive rod 21 detachable, a mating hole 111 is provided at the bottom of the housing 11, and a hollow mating post 151 is additionally provided in the mating hole 111. The upper end face of the mating post 151 abuts against the lower end face of the partition plate 12, providing a supporting force for the partition plate 12 while facilitating the assembly of the drive rod 21 through the hollow inner cavity of the mating post 151. During assembly, first insert the drive rod 21 so that the flat head of the drive rod 21 extends outside the cover plate 13, then assemble the drive gear 22 on the drive rod 21 until the teeth on the drive gear 22 mesh with the gear set 23. Mate the external thread 311 on the pressing head 31 with the internal thread 152 in the inner cavity of the mating post 151. After the pressing head 31 is screwed in, its top surface abuts against the bottom of the drive rod 21, and the upper end of the spring 32 sleeved outside the drive rod 21 abuts against the lower end face of the drive gear 22, and the lower end abuts against the upper end face of the pressing head 31. Therefore, when the pressing head 31 is screwed into the mating post 151 through the screw groove 312, the pressing force of the spring 32 on the drive gear 22 can be increased to ensure that the drive gear 22 meshes with the gear set 23. When the drive rod 21 is subjected to excessive external force, it will force the drive gear 22 to compress in the direction of the spring 32, which can protect the drive gear 22 from tooth breakage. By adjusting the spring 32, the pressing force of the drive gear 22 can be changed. In order to ensure sufficient lubrication for the rotation of the drive rod 21, a rotating post 211 is provided at the bottom of the drive rod 21, and a rotating groove 313 is provided on the upper end face of the pressing head 31. The rotating groove 313 is pre-filled with lubricating fluid or lubricating grease. After the rotating post 211 is inserted into the rotating groove 313, the rotating groove 313 can provide sufficient lubrication for the rotating post 211. In order to ensure that there is enough space in the rotating groove 313 to accommodate the lubricating fluid and the rotating post 211, a lubricating groove 314 is provided on the inner side wall of the rotating groove 313 for the excess lubricating fluid to flow out. Therefore, with sufficient lubrication, the drive rod 21 can rotate more smoothly, increasing the service life of the toilet motor 24.
[0023] The beneficial effects of the present utility model are as follows: Through the connection between the drive rod 21 and the drive gear 22, the motor 24 drives the gear set of the drive gear 22 to provide driving force, ensuring that the transmission power formed by this connection method can play the most basic transmission role. In order to facilitate the disassembly and replacement of parts, a pressing head 31 is provided. By squeezing the spring 32, a pressing force on the drive gear 22 against the gear set 23 is generated. When the drive rod 21 is subjected to excessive external force, it will force the drive gear 22 to compress in the direction of the spring 32, which can protect the drive gear 22 from tooth breakage. By adjusting the spring 32, the pressing force of the drive gear 22 can be changed.
