[0061] For new users who have just started to use electric toothbrushes, they are used to the force of brushing with ordinary toothbrushes, so they may use too much force when using electric toothbrushes, which may cause oral damage and be detrimental to the health of teeth and periodontal tissues. The present disclosure solves the above problem by detecting the force applied to the output end 211 connected to the brush head 200.

[0062] In one embodiment of the present disclosure, reference Figure 4 and Figure 5 The handle 100 of the oral cleaning device also includes a sensor assembly 4, which includes a sensor body 41 and a flexible circuit board 42 connected to the sensor body 41. The sensor body 41 is configured to be arranged on the output end 211, one end of the flexible circuit board 42 is connected to the sensor body 41, and the other end is configured to extend in the direction of the first axis in the receiving groove 220. The sensor body 41 arranged on the output end 211 can detect the force of the output end 211, and the flexible circuit board 42 can transmit the information detected by the sensor body 41 in the form of an electrical signal, thereby realizing real-time monitoring of the force of the output end 211. The user can know whether the current brushing force is appropriate, so as to adjust the force in time, which is beneficial to the health of teeth and periodontal tissues.

[0063] In one embodiment of the present disclosure, reference Figure 6 and Figure 7 The receiving groove 220 is provided with a stepped groove 2201, and the stepped groove 2201 is configured to extend along the direction of the first axis. The stepped groove 2201 can be provided on the groove bottom surface of the receiving groove 220, and the part of the flexible circuit board 42 extending into the receiving groove 220 is configured to be located in the stepped groove 2201 to form an assembly gap with the display assembly 3.

[0064] In order to ensure the normal function of the sensor assembly 4, the flexible circuit board 42 needs to remain in a relaxed state and will not be pressed or pulled by other components, otherwise it is easy to cause inaccurate measurement of the sensor assembly 4. The display assembly 3 arranged in the receiving groove 220 together with the flexible circuit board 42 is pressed on the flexible circuit board 42, so it is necessary to open a stepped groove 2201 on the bottom surface of the receiving groove 220 for accommodating the flexible circuit board 42. The flexible circuit board 42 can remain in a relaxed state in the stepped groove 2201 and will not be compacted by the display assembly 3.

[0065] In one embodiment of the present disclosure, Figure 8 As shown, one end of the flexible circuit board 42 close to the sensor body 41 is configured to be suspended at the output end 211 of the driving motor 21. Specifically, a notch 213 is provided on the output end 211, and the sensor body 41 is configured to be fixed in the notch 213 so that a gap is formed between the flexible circuit board 42 and the output end 211. When the driving motor 21 is working, the output end 211 will swing or vibrate. In order to prevent the movement of the output end 211 from affecting the accuracy of the sensor assembly 4, it is necessary to form a gap between the flexible circuit board 42 and the output end 211. The suspended flexible circuit board 42 will not be affected by the movement of the output end 211, thereby ensuring the accuracy of the sensor assembly 4.

[0066] In one embodiment of the present disclosure, reference Figure 3 , the oral cleaning appliance handle 100 also includes a control mainboard 5, which is configured to be located in the housing 1 and is configured to be in communication connection with the flexible circuit board 42, and the flexible circuit board 42 can be welded on the control mainboard 5. The control mainboard 5 can be fixed to the bracket 7 by a mainboard glue 51, and connected to various components in the oral cleaning appliance handle 100, so as to control the various components to work together. For example, it can be welded together with a control circuit located at the opposite end 212 of the drive motor 21, so as to control the drive motor 21 to be turned on or off. The control mainboard 5 is configured to determine the pressure value received by the output end 211 based on the electrical signal output by the sensor body 41, and when the pressure value is greater than the threshold value, the control mainboard 5 is configured to send a prompt signal.

[0067] Specifically, the handle 100 of the oral cleaning device further includes a light emitting component, which is configured to be partially exposed outside the housing 1 and is configured to be communicatively connected with the control main board 5. The light emitting component may include a light guide 61 and a light ring 62, wherein the light guide 61 is partially exposed outside the housing 1, and the light ring 62 is disposed inside the light guide 61, which is fixed to the bracket 7 and welded to the control main board 5, and the control main board 5 may control the light ring 62 to turn on or off, and when the light ring 62 is turned on, the user may notice the light signal through the light guide 61.

[0068] When the pressure value is greater than the threshold, the control mainboard 5 is configured to control the light emitting component to output a light signal. It is understandable that when the pressure value is greater than the threshold, it means that the user's brushing force is too strong. In order to remind the user to reduce the brushing force, the control mainboard 5 can control the light ring 62 to turn on, and the user can notice the light signal emitted by the light guide 61, thereby adjusting the brushing force, which is beneficial to protecting the health of teeth.

[0069] In one embodiment of the present disclosure, Figure 7 As shown, the flexible sleeve 22 includes a front sleeve 221 and a rear sleeve 222, and the front sleeve 221 and the rear sleeve 222 can be made of the same flexible material. The front sleeve 221 and the rear sleeve 222 are respectively configured to partially wrap the output end 211 and the opposite end 212 of the driving motor 21. The receiving groove 220 is provided on the front sleeve 221, and the display assembly 3 is completely located on the front sleeve 221, and is not partially located on the front sleeve 221 and partially located on the rear sleeve 222.

[0070] It is understandable that when the driving motor 21 vibrates during operation, the vibration may cause relative movement between the front cover 221 and the rear cover 222. If the display assembly 3 spans the front cover 221 and the rear cover 222, the display assembly 3 will be subjected to force, which may cause damage to the display assembly 3. Therefore, it is necessary to set the display assembly 3 entirely on the front cover 221, so that the display assembly 3 can move with the front cover 221 without being affected by the pulling force, thereby protecting the display assembly 3 and extending the life of the display assembly 3.

[0071] In one embodiment of the present disclosure, reference Figure 6 and Figure 7 The rear end sleeve 222 is provided with a groove 2221, which is configured to communicate with the receiving groove 220. Specifically, the groove 2221 can be configured to communicate with the stepped groove 2201. The end of the flexible circuit board 42 away from the sensor body 41 is configured to be at least partially fixed in the groove 2221, and the groove 2221 can be used to locate the installation position of the flexible circuit board 42.

[0072] In addition, if Figure 6 As shown, the end of the flexible circuit board 42 away from the sensor body 41 is provided with a connecting portion 421 fixed on the rear end sleeve 222, and the connecting portion 421 is used to be welded to the control main board 5, so as to realize the communication connection between the sensor assembly 4 and the control main board 5. The connecting portion 421 is configured to be located at a position deviated from the first axis, and the groove 2221 can play a role of reversing. The groove 2221 configured to be approximately L-shaped can make the position of the end of the flexible circuit board 42 extending along the first axis partially deviate from the first axis, so as to facilitate welding of the connecting portion 421.

[0073] In one embodiment of the present disclosure, Figure 5 As shown, the drive assembly 2 includes a flexible waterproof member 23 sleeved on the output end 211, and the outer wall of the flexible waterproof member 23 is constructed to be at least partially pre-pressed on the inner wall of the housing 1.
