Technical Field

[0001] The utility model relates to the technology of toothbrush field, in particular to an electric toothbrush with pressure sensing. Background Art

[0002] The electric toothbrush generates high-frequency vibrations through the rapid rotation or vibration of the motor core, which instantly breaks down the toothpaste into fine foam and deeply cleans the gaps between teeth. At the same time, the vibration of the bristles can promote blood circulation in the oral cavity and massage the gum tissue. There are three ways for the brush head of an electric toothbrush to move: one is reciprocating linear motion of the brush head, one is rotational motion, and there is also a set of electric toothbrushes with both types of brush heads. The bristles of the toothbrush head are made of soft plastic fibers, and the ends of the bristles are processed into spherical shapes, which will not damage the teeth and gums, and will not affect the brushing effect. Not only can every tooth be brushed clean, but it also massages the gums. There is a strong and weak conversion mode switch on the toothbrush handle, and the movement speed of the toothbrush head can be selected according to personal needs.

Therefore, it is necessary to improve the current electric toothbrushes. Utility Model Content

[0032] Please refer to Figures 1 to 4As shown, it shows the specific structure of the preferred embodiment of the present utility model, including a handle housing 10, a control board 20, a driving mechanism 30, and a brush head 40.

[0033] The handle housing 10 includes a main housing 11 and a swing frame 12. There is an accommodation cavity 101 inside the main housing 11. The swing frame 12 is arranged in the accommodation cavity 101 so as to be swingable up and down. A magnetic induction component 50 is arranged between the swing frame 12 and the main housing 11. The magnetic induction component 50 is electrically connected to the control board 20. And an elastic member 60 for urging the swing frame 12 to reset horizontally is arranged between the swing frame 12 and the main housing 11. In this embodiment, there is an inner frame 111 inside the main housing 11. The magnetic induction component 50 is located between the inner frame 111 and the swing frame 12. Specifically, the magnetic induction component 50 includes an induction coil 51 and a trigger member 52. The induction coil 51 is fixed on the inner frame 111 and electrically connected to the control board 20. The trigger member 52 is fixed on the swing frame 12 and hangs above the induction coil 51. The trigger member 52 approaches or moves away from the induction coil 51 as the swing frame 12 swings back and forth. The structure is simple, stable and reliable. And, the trigger member 52 includes a plastic frame 521 and a copper sheet 522. The plastic frame 521 is fixedly connected to the swing frame 12 by snap connection. The copper sheet 522 is attached to the plastic frame 521 and faces the induction coil 51. The structure is simple and convenient for assembly. The elastic member 60 is a return spring. The return spring is arranged on the inner frame 111 and abuts against the bottom of the rear end of the swing frame 12. And, a through hole 102 is opened on the front end face of the main housing 11. The through hole 102 communicates with the accommodation cavity 101. A waterproof rubber sleeve 13 is arranged in the through hole 102.

[0034] The control board 20 is arranged inside the handle housing 10. The control board 20 has a control button 21. The control button 21 is exposed on the outer surface of the handle housing 10. The driving mechanism 30 is arranged inside the handle housing 10 and connected to the control board 20. The driving mechanism 30 includes a driving rod 31. The driving rod 31 extends forward out of the handle housing 10. Specifically, the driving mechanism 30 is arranged on the swing frame 12 and swings up and down with the swing frame 12. In this embodiment, the control board 20 is fixed on the inner frame 111. The swing frame 12 is arranged on the inner frame 111 so as to be swingable up and down. The control board 20 is fixed on the inner frame 111. And, the driving rod 31 passes through the waterproof rubber sleeve 13 and extends forward out of the accommodation cavity 101. The driving rod 31 has a clearance fit with the through hole 102, so that the driving rod 31 can swing back and forth at a small angle up and down. At the same time, the waterproof rubber sleeve 13 has a certain elasticity, so that the driving rod 31 can cooperate with the action of the elastic member 60 to keep in the horizontal position when not stressed.

[0035] The brush head 40 is inserted and mounted on the drive rod 31 and is driven by the drive rod 31 to move. The brush head 40 swings up and down with the drive mechanism 30. There is a clearance fit between the rear end face of the brush head 40 and the front end face of the handle housing 10, so that the brush head 40 can swing up and down relative to the handle housing 10.

[0036] And an indicating device 71 is arranged in the handle housing 10, and the indicating device 71 is electrically connected to the control board 20. In this embodiment, the indicating device 71 is an indicator light board, which is fixed to the front end of the inner frame 111, and the light generated by the indicator light board shines out through the handle housing 10. In addition, a storage battery 72 is fixed on the inner frame 111, and the storage battery 72 is electrically connected to the control board 20 to provide power for the drive mechanism 30, the indicating device 71, etc.

[0037] The working principle of this embodiment is described in detail as follows:

[0038] When in use, hold the handle housing 10 by hand, put the brush head 40 smeared with toothpaste into the mouth, and then start the drive mechanism 30 by operating the control button 21. The drive mechanism 30 drives the brush head 40 to move to brush the teeth. During the brushing process, the user applies pressure on the handle housing 10 so that the brush head 40 can better press against the teeth for brushing. As the pressure changes, the trigger 52 approaches or moves away from the induction coil 51. Specifically, when the pressure on the brush head 40 increases, the swing frame 12 is pressed to swing, causing the trigger 52 to approach the induction coil 51, so that the control board 20 controls the red light of the indicating device 71 to turn on from dim to bright to indicate an increase in pressure. At the same time, the control board 20 also correspondingly controls the operating speed of the drive mechanism 30 to decrease; when the pressure on the brush head 40 decreases, the swing frame 12 returns to the horizontal under the action of the elastic member 60, causing the trigger 52 to move away from the induction coil 51, so that the control board 20 controls the green light of the indicating device 71 to turn on from dim to bright to indicate a decrease in pressure. At the same time, the control board 20 also correspondingly controls the operating speed of the drive mechanism 30 to increase.

[0039] The design focus of the present utility model lies in: by arranging the drive mechanism on the swing frame to swing up and down with the swing frame, and cooperating with a magnetic induction component arranged between the swing frame and the main housing, the magnetic induction component can be used for pressure sensing, and the control board controls the indicating device and the drive mechanism accordingly according to the pressure magnitude. The indicating device can give a prompt to the user to change the pressure magnitude, and the operating speed of the drive mechanism also changes accordingly, thereby effectively avoiding damage due to excessive load and bringing convenience to use.

[0040] The above are only the preferred embodiments of the present utility model, and do not impose any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
