[0062] Electric toothbrushes are widely popular in the market because of their good cleaning effect. When an electric toothbrush is working, the drive component (motor) drives the brush head to produce high-frequency vibrations, breaking down toothpaste into fine foam and deeply cleaning the gaps between teeth. At the same time, the vibration of the bristles can promote blood circulation in the oral cavity and have a massage effect on the gum tissue. However, the gum tissue is relatively fragile. When the vibration intensity of the electric toothbrush bristles exceeds a certain threshold, it will cause damage to the gum tissue.
[0063] Based on the problem in the prior art that the brush head of an electric toothbrush can easily damage gum tissue due to excessive vibration intensity, the present invention provides a gum protection structure and an electric toothbrush. A detection mechanism is provided, and the detection mechanism is provided on the electric toothbrush body, so that the vibration intensity of the drive assembly and the brush head assembly can be detected in real time. While the drive assembly drives the brush head assembly to vibrate, it is also subjected to the reaction force of the brush head assembly, so that the vibration intensity of the brush head assembly can be indirectly and synchronously reflected through the swing degree of the drive assembly. When the swing amplitude of the drive assembly exceeds a threshold value, the drive assembly triggers the detection mechanism, so as to reduce the operating power of the drive assembly, so that the electric toothbrush enters a weak gear mode, thereby effectively protecting the gum tissue. For details, please refer to the following embodiments.
[0064] Please refer to further Figure 1 and Figure 2 In the first embodiment of the present invention, a gum protection structure 10 is provided, and the gum protection structure 10 is used for an electric toothbrush; the gum protection structure 10 includes: an electric toothbrush body 15 and a detection mechanism 16; the electric toothbrush body 15 includes a driving component 12 and a brush head component 13, and the brush head component 13 is transmission-connected with the driving component 12, that is, the driving component 12 is used to drive the brush head component 13; the detection mechanism 16 is arranged on the electric toothbrush body 15, and is used to detect the vibration intensity of the driving component 12 and the brush head component 13, and when the swing amplitude of the driving component 12 exceeds a threshold value, the driving component 12 triggers the detection mechanism 16, and the detection mechanism 16 adjusts the operating power of the driving component 12 when triggered.
[0065] It can be understood that when the swing amplitude of the drive component 12 exceeds the threshold value, the drive component 12 triggers the detection mechanism 16, so that the detection mechanism 16 timely adjusts the operating power of the drive component 12, thereby realizing real-time detection and adjustment of the vibration intensity of the brush head component 13; specifically, by setting the detection mechanism 16 and setting the detection mechanism 16 on the electric toothbrush body 15, the vibration intensity of the drive component 12 and the brush head component 13 can be detected in real time; while the drive component 12 drives the brush head component 13 to vibrate, it is also subjected to the reaction force of the brush head component 13, and then the vibration intensity of the brush head component 13 can be indirectly and synchronously reflected through the swing degree of the drive component 12, and then when the swing amplitude of the drive component 12 exceeds the threshold value, the drive component 12 triggers the detection mechanism 16, thereby reducing the operating power of the drive component 12, so that the electric toothbrush enters the weak gear mode, thereby effectively protecting the gum tissue.

[0067] It should be noted that the trigger assembly 14 can also be arranged at the junction of the driving assembly 12 and the brush head assembly 13, or be arranged on the brush head assembly 13. In this embodiment, it is preferred to arrange the trigger assembly 14 at the lower end relative to the second end of the driving assembly 12 along the axial direction. It can be understood that by dynamically connecting the first end of the drive assembly 12 along the axial direction with the drive fixing assembly 11, the first end of the drive assembly 12 along the axial direction and the drive fixing assembly 11 are made to swing, and by controlling one end of the brush head assembly 13 along the axial direction to be connected to the first end of the drive assembly 12, the drive assembly 12 is also subjected to the reaction force of the brush head assembly 13 while driving the brush head assembly 13 to vibrate, and because the end of the drive assembly 12 close to the brush head assembly 13 is dynamically connected to the drive fixing assembly 11, the drive assembly 12 is made to swing synchronously, and the vibration intensity of the brush head assembly 13 can be indirectly reflected by the swing degree of the drive assembly 12, and the trigger assembly 14 is provided at the relatively lower end of the second end of the drive assembly 12 along the axial direction, and when the swing amplitude of the drive assembly 12 exceeds the threshold value, the drive assembly 12 presses to trigger the trigger assembly 14, thereby reducing the operating power of the drive assembly 12, so that the electric toothbrush 1 enters the weak gear mode, thereby effectively protecting the gingival tissue.
[0068] In some other preferred embodiments, the trigger component 14 includes: a PCB board 141, a first electrode spring 142 and a second electrode spring 143; the PCB board 141 is electrically connected to the drive component 12; the first electrode spring 142 is arranged on the PCB board 141; the second electrode spring 143 is arranged on the PCB board 141 and is spaced apart from the first electrode spring 142; the first electrode spring 142 is arranged between the second electrode spring 143 and the second end of the drive component 12; it can be understood that the PCB board 141 connects the drive component 12 to the electrode The first electrode spring 142, the first electrode spring 143 and the second end of the driving component 12 are at least partially located on the same radial cross-section, thereby ensuring that when the vibration of the brush head component 13 exceeds a threshold value, the driving component 12 swings beyond the threshold value, thereby causing the second end of the driving component 12 to press against the first electrode spring 142, so that the first electrode spring 142 contacts and presses against the second electrode spring 143, so that the triggering component 14 is triggered, thereby reducing the operating power of the driving component 12, and causing the electric toothbrush 1 to enter a weak gear mode, thereby effectively protecting the gum tissue.

It can be understood that by setting the first and second suspension members 1113 and 1114, the first and second suspension members 1113 and 1114 form a fulcrum, and when the brush head assembly 13 vibrates, the motor 121 is driven to swing and rotate slightly around the first and second suspension members 1113 and 1114, thereby providing a guarantee for the swing block 122 to trigger the trigger assembly 14.
