Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides a technical solution: a fixed bracket cleaning device for orthodontics, as Figure 1 shown, comprising a clamping mechanism 100, a cleaning mechanism 200, a housing 101 and a base 102. The housing 101 is slidably disposed on the base 102. Two sets of clamping mechanisms 100 are disposed in the housing 101. The clamping mechanism 100 includes a clamping sleeve 103, a clamping rod 104, a clamp component 106 and a limiting component 105. The clamping sleeve 103 is rotatably disposed at the bottom of the housing 101. The limiting component 105 is disposed at the bottom of the housing 101, and the limiting component 105 can limit the rotation of the clamping sleeve 103. The clamping rod 104 is slidably disposed in the clamping sleeve 103. The end of the clamping rod 104 is provided with a clamp component 106, and the clamp component 106 can clamp a fixed bracket.

[0025] The cleaning mechanism 200 includes a stepper motor 201 and a swing sleeve 202. The swing sleeve 202 is rotatably arranged on the base 102. The stepper motor 201 is fixed on the base 102. The stepper motor 201 can drive the swing sleeve 202 to swing back and forth. One end of a connecting rod 207 can be hinged to the swing sleeve 202, and the other end of the connecting rod 207 can be hinged to the housing 101. A cleaning brush 203 is detachably and slidably arranged in the swing sleeve 202. When the swing sleeve 202 swings, the distances from each point on the fixed bracket to the swing center are different, and relative sliding occurs between the cleaning brush 203 and the swing sleeve 202, ensuring that the cleaning brush 203 always moves along the fixed bracket and adapts to the irregular curve of the fixed bracket.

[0026] As Figure 3 shown, in order to facilitate the clamping of the fixed bracket, the clamp assembly 106 includes a fixed pin 110, a sliding pin 111 and a spring 112. The fixed pin 110 is fixed at the end of the clamping rod 104. A chute is formed on the clamping rod 104. The sliding pin 111 is slidably arranged on the chute, and a spring 112 is fixed in the chute. The spring 112 can press the sliding pin 111 against the fixed pin 110.

[0027] As Figure 2 shown, in order to facilitate the restriction of the rotation of the clamping mechanism 100, the limiting assembly 105 includes a clamping gear 107, an intermediate gear 108 and a movable gear 109. The clamping gear 107 is coaxially fixed with the clamping sleeve 103. The clamping gear 107 meshes with both the intermediate gear 108 and the movable gear 109. The intermediate gear 108 meshes with the movable gear 109. The intermediate gear 108 is rotatably arranged in the housing 101, and the movable gear 109 is detachably arranged in the housing 101. When the clamping gear 107, the intermediate gear 108 and the movable gear 109 are all meshed with each other, they cannot rotate, fixing the clamping sleeve 103. By removing the movable gear 109 and rotating the clamping sleeve 103, the clamping sleeve 103 drives the clamping gear 107 to rotate in the same direction and the intermediate gear 108 to rotate in the opposite direction.

[0028] As Figure 1 shown, in order to facilitate the transmission of the power of the stepper motor 201, a synchronous pulley is coaxially fixed to the swing sleeve 202. The stepper motor 201 drives the swing sleeve 202 through a synchronous belt 217. The stepper motor 201 is electrically connected to a stepper motor controller, which is a common electrical component that can set the angular displacement and the number of working cycles of the stepper motor 201 through buttons.

[0029] As Figure 2As shown in the figure, a fixed brush head 204 is fixed at the end of the cleaning brush 203, and a sliding brush head 205 is slidably arranged on the cleaning brush 203. One end of a tension spring 206 is fixed on the sliding brush head 205, and the other end of the tension spring 206 is fixed at the end of the cleaning brush 203. The fixed brush head 204 and the sliding brush head 205 are made of arc-shaped elastic pieces, and bristles are fixed on the fixed brush head 204 and the sliding brush head 205. The tension spring 206 pulls the fixed brush head 204 and the sliding brush head 205 closer, ensuring that the cleaning brush 203 always slides along the fixed bracket, preventing it from falling off, and can also adapt to the difference in the inner and outer curves of the fixed bracket.

[0030] As Figure 4 shown in the figure, in order to facilitate flushing away the residual cleaning liquid on the fixed bracket, the swing sleeve 202 can be disassembled. The connection mode between the swing sleeve 202 and the connecting rod 207 is detachable. A flushing brush 208 is slidably arranged in the swing sleeve 202 in a detachable manner. The flushing brush 208 can replace the cleaning brush 203. A waterproof motor 209 is fixed at the end of the flushing brush 208. The output shaft of the waterproof motor 209 is connected to the roller brush 210 through a coupling. A water outlet pipe 211 is fixed on the flushing brush 208, and the outlet of the water outlet pipe 211 faces the roller brush 210. A drain valve 218 is fixed at the bottom of the housing 101, and a locking component 212 is arranged on the base 102. The locking component 212 can fix the housing 101.

[0031] Before the flushing work, it is necessary to drain the cleaning liquid in the housing 101 first. Therefore, the housing 101 does not need to move during the flushing work. Removing the connecting rod 207 and locking the housing 101 prevent the movement of the housing 101, reduce the load of the swing sleeve 202, and save energy.

[0032] As Figure 5 shown in the figure, in order to improve the flushing effect, the coupling includes two half couplings 213 and a return spring 214. The two half couplings 213 can slide relative to each other, and the return spring 214 is fixed between the two half couplings 213. A protrusion 215 is fixed on the end face of the roller brush 210 facing the waterproof motor 209, and a convex column 216 is fixed on the end face of the waterproof motor 209 facing the roller brush 210. The return spring 214 can pull the roller brush 210 and the waterproof motor 209 closer, and the protrusion 215 and the convex column 216 can push the roller brush 210 and the waterproof motor 209 apart. The waterproof motor 209 can drive the roller brush 210 to rotate, and the convex column 216 can intermittently contact the protrusion 215, thereby pushing the roller brush 210 away. The return spring 214 can pull the roller brush 210 closer, so that the roller brush 210 can vibrate up and down while rotating, improving the flushing effect.

[0033] As Figure 4As shown, to facilitate the fixing of the housing 101, the locking assembly 212 includes a bolt and a lock hole. The bolt is threadedly connected to the base 102, and the lock hole is formed in the housing 101. Slide the housing 101 to align the lock hole thereon with the bolt, and rotate the bolt to insert it into the lock hole to lock the housing 101.

[0034] Working process: The operator injects cleaning liquid into the housing 101. By adjusting the movable clamping rod 104 and rotating the clamping sleeve 103, the clamping jaw assembly 106 can be flexibly moved. There are two sets of clamping mechanisms 100 in total. The two sets of clamping mechanisms 100 limit the fixed bracket through two points on the clamping fixed bracket. The operator uses the limit assembly 105 to limit the rotation of the clamping sleeve 103, and adjusts the two clamping sleeves 103 to be non-parallel to each other. After clamping the fixed bracket, the clamping rod 104 cannot slide;

[0035] The operator sets the number of working cycles and angular displacement of the stepping motor 201 through the stepping motor controller. The swing sleeve 202 swings back and forth, and the cleaning brush 203 cleans along the surface of the fixed bracket. The swing sleeve 202 can also drive the housing 101 to vibrate through the connecting rod 207, improving the foaming effect of the cleaning liquid, and thus improving the cleaning effect;

[0036] After the cleaning work is completed, first drain the cleaning liquid, then replace the cleaning brush 203 with the flushing brush 208, remove the connecting rod 207, fix the housing 101 through the locking assembly 212, and prepare for the flushing work to remove the cleaning liquid on the fixed bracket. The flushing brush 208 flushes along the surface of the fixed bracket, and the water outlet pipe 211 is connected to the water source for flushing. The waterproof motor 209 drives the rotary brush 210 to rotate and vibrate up and down to improve the flushing effect.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
