Description

Technical Field

[0001] This application relates to the field of household appliances, and in particular to an electric toothbrush paddle control system. Background Technology

[0002] Electric toothbrushes are becoming a common daily tool, and their convenience and efficiency have led to their widespread use.

[0003] A typical electric toothbrush mainly consists of a handle and a brush head. The brush head is detachably mounted on the handle, which houses the battery, control circuit board, and motor. The handle has a slot for inserting the brush head's mounting end. The end of the brush head that extends into the slot is detachably connected to the motor's drive shaft. The battery powers the motor, and the control circuit board is connected to buttons on the handle and controls the motor. The operator can turn the electric toothbrush on or off using the buttons on the handle.

[0004] In the prior art, a patent with publication number CN115040281B discloses a multifunctional electric toothbrush. The toothbrush has a nozzle slidably installed in a groove in the brush head, and a lever is slidably installed on the handle. A water supply pipe for supplying water to the nozzle is fixed on the lever. The user can move the nozzle up or down by moving the lever up and down. A water pump is installed in the handle, and a water storage tank is opened in the handle. The water inlet of the water supply pipe extends into the water storage tank, so that the user can rinse the mouth after brushing.

[0005] However, the method of adjusting the position of the nozzle by sliding the lever is rather cumbersome, and users need to use their fingers to hold the lever in place while rinsing their mouths, which is inconvenient and needs improvement. Utility Model Content

[0006] To improve the convenience of using electric toothbrushes, this application provides an electric toothbrush paddle control system.

[0007] The electric toothbrush paddle control system provided in this application adopts the following technical solution:

[0008] An electric toothbrush paddle control system includes a partition fixedly installed inside the grip, a sliding hole through which a water supply pipe extends, a paddle adjustablely mounted above the partition, and a water supply pipe fixedly mounted on the paddle; and:

[0009] The control buttons are fixedly mounted on the grip.

[0010] A drive mechanism is fixedly mounted on the partition. The drive end is fixedly connected to the paddle, and the signal input end is connected to the signal output end of the control button. It is used to drive the paddle to move toward or away from the partition.

[0011] By adopting the above technical solution, when a user finishes brushing their teeth and needs to rinse their mouth, they can press the control button to input a first control signal. Upon receiving the first control signal, the drive mechanism drives the paddle to move, causing the water supply pipe and the nozzle at its end to extend from the brush head. After rinsing, the user can press the control button again to input a second control signal. Upon receiving the second control signal, the drive mechanism drives the paddle to move downwards, causing the water supply pipe and the nozzle at its end to return to their original positions. Through the coordinated use of the control button, drive mechanism, and paddle, the ease with which the user can remove the water supply pipe and nozzle, and the ease of rinsing their mouth, can be effectively improved.

[0012] Preferably, the drive mechanism includes an electric telescopic cylinder, the cylinder body of which is fixedly installed at the bottom of the partition, and the drive shaft of which passes through the partition and is fixedly connected to the lever.

[0013] The signal input terminal of the electric telescopic cylinder is connected to the signal output terminal of the control button.

[0014] By adopting the above technical solution, the electric telescopic cylinder's extension or retraction drive shaft can drive the paddle to move towards or away from the partition, thereby achieving the technical effect of automatically driving the water supply pipe and nozzle to extend or retract.

[0015] Preferably, a guide rod is fixedly installed on the partition plate. The guide rod is located on the side of the water supply pipe away from the electric telescopic cylinder. The paddle has a guide hole that matches the guide rod. The electric telescopic cylinder drives the paddle to move up and down along the axial direction of the guide rod.

[0016] By adopting the above technical solution, the guide rod restricts the position of the lever during the lifting and lowering process, which can effectively reduce the occurrence of water pipeline deviation.

[0017] Preferably, a positioning plate is fixedly installed on the water supply pipeline, and the positioning plate is located directly below the lever.

[0018] A connecting rod is fixedly connected between the paddle and the positioning plate, and a through hole is provided on the partition plate for the connecting rod to pass through.

[0019] By adopting the above technical solution and setting the positioning plate, it can be ensured that the section of the water pipeline that slides in the sliding hole on the partition always slides in the up and down direction, thus preventing the water pipeline from accumulating on the partition or being damaged by friction with the inner wall of the sliding hole during the up and down movement.

[0020] Preferably, an ultrasonic ranging sensor is fixedly installed inside the grip, and the signal input terminal of the ultrasonic ranging sensor is connected to the signal output terminal of the control button.

[0021] The ultrasonic ranging sensor is located directly below the partition, with its sensing end facing the positioning plate. The ultrasonic ranging sensor detects the distance between itself and the positioning plate and outputs a sensing distance signal.

[0022] The signal output terminal of the ultrasonic ranging sensor is connected to a comparator. The comparator chip receives the sensed distance signal and outputs a water spray control signal.

[0023] The signal output terminal of the comparator is connected to the signal input terminal of the water pump inside the grip. The water pump receives the water spray control signal and draws water from the water storage chamber and sprays it out through the nozzle.

[0024] By adopting the above technical solution, during the process of the electric telescopic cylinder driving the paddle to move upward, exposing the water supply pipe and nozzle, the ultrasonic ranging sensor detects the position of the positioning plate in real time. When the height of the positioning plate reaches a certain height and the nozzle and water supply pipe extend out of the groove on the brush head, the comparator controls the water pump to start, which can achieve the effect of automatic water output. When the user finishes rinsing and presses the control button again to input the second control signal, the paddle and positioning plate move downward, the water pump automatically shuts off, and the water spraying stops, which can achieve the technical effect of automatically stopping water output.

[0025] In summary, the electric toothbrush paddle control system of this application has at least one of the following beneficial technical effects:

[0026] 1. When a user finishes brushing their teeth and needs to rinse their mouth, they can press the control button to input a first control signal. After receiving the first control signal, the drive mechanism drives the paddle to move, causing the water pipe and the nozzle at the end of the water pipe to extend out of the brush head. After rinsing, the user can press the control button again to input a second control signal. After receiving the second control signal, the drive mechanism drives the paddle to move down, causing the water pipe and the nozzle at the end of the water pipe to return to their original positions.

[0027] 2. During the process of the electric telescopic cylinder driving the paddle to move upward, exposing the water supply pipe and nozzle, the ultrasonic ranging sensor detects the position of the positioning plate in real time. When the height of the positioning plate reaches a certain height and the nozzle and water supply pipe extend out of the groove on the brush head, the comparator controls the water pump to start, which can achieve the effect of automatic water output. When the user finishes rinsing and presses the control button again to input the second control signal, the paddle and positioning plate move downward, the water pump automatically shuts off, and the water spraying stops, which can achieve the technical effect of automatically stopping water output.

[0031] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0032] Example

[0033] This application discloses a control system for an electric toothbrush paddle 3. (Refer to...) Figure 1 and Figure 2 It mainly includes a partition 2 fixedly installed inside the grip part 1, a sliding hole 21 through which a water supply pipe 11 extends, a lever 3 that can be adjusted and raised above the partition 2, and the water supply pipe 11 fixedly installed on the lever 3; and a control button 4 fixedly installed on the grip part 1; and a drive mechanism 5 fixedly installed on the partition 2, the drive end of which is fixedly connected to the lever 3, and the signal input end is connected to the signal output end of the control button 4, for driving the lever 3 to move toward or away from the partition 2.

[0034] When a user finishes brushing their teeth and needs to rinse their mouth, they can press control button 4 to input a first control signal. Upon receiving this signal, drive mechanism 5 moves the lever 3, causing the water supply pipe 11 and the nozzle 12 at its end to extend from the brush head. After rinsing, the user can press control button 4 again to input a second control signal. Upon receiving this signal, drive mechanism 5 moves the lever 3 downwards, resetting the water supply pipe 11 and the nozzle 12. The coordinated use of control button 4, drive mechanism 5, and lever 3 effectively improves the ease with which the user can remove the water supply pipe 11 and nozzle 12, thus enhancing the ease of rinsing the mouth.

[0035] Reference Figure 2 In this embodiment, the drive mechanism 5 is an electric telescopic cylinder 51. The cylinder body of the electric telescopic cylinder 51 is fixedly installed at the bottom of the partition 2. The drive shaft of the electric telescopic cylinder 51 passes through the partition 2 and is fixedly connected to the lever 3. The signal input end of the electric telescopic cylinder 51 is connected to the signal output end of the control button 4.

[0036] The electric telescopic cylinder 51 extends or retracts the drive shaft, which can drive the paddle 3 to move toward or away from the partition 2, thereby achieving the technical effect of automatically driving the water supply pipe 11 and the nozzle 12 to extend or retract.

[0037] Reference Figure 2 A guide rod 22 is fixedly installed on the partition plate 2. The guide rod 22 is located on the side of the water supply pipe 11 away from the electric telescopic cylinder 51. The paddle 3 has a guide hole that matches the guide rod 22. The electric telescopic cylinder 51 drives the paddle 3 to move up and down along the axial direction of the guide rod 22.

[0038] The guide rod 22 restricts the position of the lever 3 during the lifting and lowering process, which can effectively reduce the occurrence of water pipe 11 deviation.

[0039] Reference Figure 2 A positioning plate 7 is fixedly installed on the water supply pipe 11, and the positioning plate 7 is located directly below the lever 3; a connecting rod 71 is fixedly connected between the lever 3 and the positioning plate 7, and a through hole 23 is provided on the partition plate 2 for the connecting rod 71 to pass through.

[0040] By setting the positioning plate 7, it can be ensured that the section of the water supply pipe 11 that slides in the sliding hole 21 on the partition plate 2 always slides in the up and down direction, so as to prevent the water supply pipe 11 from accumulating on the partition plate 2 or being damaged by friction with the inner wall of the sliding hole 21 during the up and down movement.

[0041] Reference Figure 2An ultrasonic ranging sensor 8 is fixedly installed inside the grip 1. The ultrasonic ranging sensor 8 is fixedly installed at the bottom of the partition 2 by adhesive bonding. The signal input terminal of the ultrasonic ranging sensor 8 is connected to the signal output terminal of the control button 4. The ultrasonic ranging sensor 8 is located directly below the partition 2, and the sensing end of the ultrasonic ranging sensor 8 is set facing the positioning plate 7. The ultrasonic ranging sensor 8 detects the distance between itself and the positioning plate 7 and outputs a sensing distance signal. The signal output terminal of the ultrasonic ranging sensor 8 is connected to a comparator. The comparator chip receives the sensing distance signal and outputs a water spray control signal. The signal output terminal of the comparator is connected to the signal input terminal of the water pump 13 inside the grip 1. The water pump 13 receives the water spray control signal and draws water from the water storage chamber and sprays it out through the nozzle 12.

[0042] During the process of the electric telescopic cylinder 51 driving the paddle 3 to move upward, causing the water supply pipe 11 and the nozzle 12 to be exposed, the ultrasonic ranging sensor 8 detects the position of the positioning plate 7 in real time. When the height of the positioning plate 7 reaches a certain height and the nozzle 12 and the water supply pipe 11 extend out of the groove on the brush head, the comparator controls the water pump 13 to start, which can achieve the effect of automatic water output. When the user finishes rinsing and presses the control button 4 again to input the second control signal, the paddle 3 and the positioning plate 7 move downward, the water pump 13 automatically shuts off, and the water spraying stops, which can achieve the technical effect of automatically stopping the water output.

[0043] The implementation principle of the electric toothbrush paddle 3 control system in this embodiment is as follows: When the user finishes brushing their teeth and needs to rinse their mouth, they can press the control button 4 to input a first control signal. After receiving the first control signal, the drive mechanism 5 drives the paddle 3 to move, causing the water supply pipe 11 and the nozzle 12 at the end of the water supply pipe 11 to extend out of the brush head. After rinsing, the user can press the control button 4 again to input a second control signal. After receiving the second control signal, the drive mechanism 5 drives the paddle 3 to move down, causing the water supply pipe 11 and the nozzle 12 at the end of the water supply pipe 11 to return to their original positions. Through the interaction and use of the control button 4, the drive mechanism 5, and the paddle 3, the ease with which the user can remove the water supply pipe 11 and the nozzle 12 can be effectively improved, thus enhancing the ease with which the user can rinse their mouth.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
