The following embodiments are only used to illustrate the technical solution of the present utility model more clearly, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0025] Please refer to Figure 1 , Figure 1 The structure diagram of the button pressure-sensing electric toothbrush provided by the embodiment of the present utility model is shown. The button pressure-sensing electric toothbrush includes: toothbrush head 110, housing 120, control button 130 provided on the surface of the housing 110, conductive elastic member 151 provided in the housing, button pressure sensor 152, movement assembly 200, control main board 220, and touch sensing chip (not shown in the figure). The button pressure-sensing electric toothbrush includes: toothbrush head 110, housing 120, control button 130 provided on the surface of the housing 110, conductive elastic member 151 provided in the housing, button pressure sensor 152, movement assembly 200, control main board 220, and touch sensing chip (not shown in the figure).

[0026] Please refer to Figure 3 , Figure 3The figure shows an exploded structural schematic diagram of a button pressure-sensing electric toothbrush provided by an embodiment of the present invention. The top of the housing 120 is open, and the toothbrush head 110 is installed at the top of the housing and connected to the movement assembly 200 through the open top of the housing 120.

[0027] Please refer to Figure 2 , Figure 2 The figure shows a cross-sectional structural schematic diagram of a button pressure-sensing electric toothbrush provided by an embodiment of the present invention. One end of the conductive elastic member 151 abuts against the inner surface of the control button 130, and the other end is electrically connected to the control main board 220; the touch sensing chip is provided on the control main board 220, and the touch sensing chip is used to obtain a first trigger signal when the control button 130 is triggered by a human body through the conductive elastic member 151.

[0028] Wherein, the button pressure sensor 152 is arranged between the conductive elastic member 151 and the control main board 220, and the button pressure sensor 152 is electrically connected to the control main board 220; the button pressure sensor 152 is used to detect a first pressure when the control button 130 is pressed through the conductive elastic member 151, and when it detects that the first pressure is greater than a first preset pressure value, it sends a first start signal to the control main board 220. The first preset pressure value can be set by those skilled in the art according to specific application situations, and this application does not make any restrictions.

[0029] Wherein, the control main board 200 is further used to power on and start according to the first start signal, and drive the toothbrush head 110 to vibrate at a first vibration frequency when receiving the first trigger signal, so that the button pressure-sensing electric toothbrush enters the working mode.

[0030] Specifically, a touch sensing portion 1511 is arranged on the surface of the conductive elastic member 151 that abuts against the control button 130. The touch sensing portion 1511 on the conductive elastic member 151 communicates with the touch sensing chip to form a touch sensor. When a human body touches the control button 130, the dielectric constant of the conductive elastic member 151 changes, causing a change in the touch sensing sensitivity capacitance between the conductive elastic member 151 and the touch sensing chip. The touch sensing chip is used to detect the change amount of the touch sensing sensitivity capacitance, determine whether the control button 130 is triggered by a human body, and when it detects that the control button 130 is triggered by a human body, it sends a first trigger signal to the control main board 220.

[0031] Among them, the size of the conductive elastic member 151 is larger than that of the button pressure sensor 152, and the conductive elastic member 151 covers the button pressure sensor 152; the conductive elastic member 151 is further configured to absorb the first pressure received by the control button 130 and transmit it to the button pressure sensor 152, and the button pressure sensor 152 is configured to detect the first pressure received by the control button 130 through the conductive elastic member 151, and when it detects that the first pressure is greater than the first preset pressure value, send the first start signal to the control main board 220. The first preset pressure value can be set by those skilled in the art according to the actual application scenario.

[0032] Among them, the conductive elastic member 151 can be made of conductive silica gel.

[0033] In the embodiment of the present utility model, by sequentially arranging the control button 130, the elastic pressure member 151, the button pressure sensor 152 and the touch sensing chip, not only can the first pressure received by the control button 130 be detected, and the first start signal be sent when it detects that the first pressure is greater than the first preset pressure value, but also it can be determined whether the control button 130 is triggered by a human body, and a first trigger signal is generated when the human body triggers. In this way, the button pressure sensing electric toothbrush drives the toothbrush head 110 to vibrate only when receiving the first start signal and the first trigger signal, which can effectively avoid the accidental startup of the button pressure sensing electric toothbrush caused by accidental pressing of the control button 130, and has high reliability and stability. While ensuring the sensing sensitivity of the control button 130, it can effectively suppress and eliminate the interference of the surrounding electrical environment.

[0034] Among them, the control button 130 and the housing 120 are integrally designed. Optionally, a side wall on the outer surface of the housing 120 is recessed inward to form the control button 130, and the thickness of the control button 130 is less than the thickness of the side wall of the housing 120 except for the control button 130; the control button 130 is made of deformable material for the user to press, and the elastic conductive member 151 is configured to absorb the elastic deformation pressure of the control button 130.

[0035] In the embodiment of the present utility model, by setting the control button 130 and the housing 120 to be integrally designed, and the control button 130 is made of deformable material, there is no need to use a button with a certain physical movement stroke, and there is no need to open a hole in the housing 120, which improves the waterproof performance of the housing 120.

The toothbrush head connecting member 111 is fitted in the bottom opening of the toothbrush head 110.

[0040] Among them, the top cover 2311 is made of a soft material for absorbing the processing error of the housing 120, and the soft material top cover 2311 can reduce the vibration feeling and noise when the magnetic levitation motor 230 operates.

[0041] Among them, the waterproof ring 2312 is disposed at the top opening of the housing 120 for preventing external water vapor from entering through the top opening of the housing 120 to protect the movement assembly 200.

[0042] Among them, the movement assembly 200 further includes a movement bracket 250. The movement bracket 250 is respectively provided with channel structures for accommodating the battery 210 and the magnetic levitation motor 230. The battery 210 and the magnetic levitation motor 230 are fixed in the channel structures of the movement bracket 250. The movement bracket 250 is fixedly connected to the housing 120.

[0044] Among them, the motor end cover 233 is made of a soft material, which is used to eliminate the machining error of the housing 120 and reduce the vibration and noise during the operation of the magnetic levitation motor 230.

[0045] In the embodiment of the present utility model, by providing the soft top cover 2311 and the motor end cover 233 at both ends of the magnetic levitation motor 230, the machining error of the housing 120 can be effectively eliminated, the assembly stability between components can be improved, so as to reduce the noise generated during the operation of the magnetic levitation motor 230 and improve the earthquake resistance effect of the housing 120.

[0047] In an embodiment of the present utility model, the number of the control buttons 130 is set to one, which is used to send a first start signal, a mode adjustment signal or a stop signal to the control main board 220 according to the number of times the user triggers the control button 130.

[0048] In another embodiment of the present utility model, the control button 130 is set as a start button for sending a first start signal, a mode adjustment button for sending a mode adjustment signal and a stop button for sending a stop signal.

[0049] See Figure 4 , on one side of the control main board 220 facing the side wall of the housing 120, a plurality of mode indicators 222 for representing different modes are provided; the side wall of the mode indicator 222 facing the housing 120 is made of a light-transmitting material. It can be understood that according to the mode adjustment signal, the control main board 220 controls different mode indicators 222 to light up, and the vibration frequencies of the toothbrush head 110 corresponding to different working modes are different.

[0050] Among them, on one side of the control main board 220 facing the side wall of the housing 120, a light-shielding sheet 221 is further provided, and the light-shielding sheet 221 is provided with a plurality of through holes for accommodating the mode indicators 220; the mode indicators 220 pass through the through holes of the light-shielding sheet 221 one by one, and the light-shielding sheet 221 is used to prevent light leakage between adjacent mode indicators 220.

[0051] Among them, the bottom of the housing 120 is open, and the housing 120 further includes a bottom case 121 disposed at the bottom opening. The movement assembly 200 is encapsulated between the inner wall of the housing 120 and the inner surface of the bottom case 121.

[0052] Among them, the button pressure-sensing electric toothbrush further includes a charging port assembly 240. The bottom case 121 is provided with an opening for accommodating the charging port assembly 240. The charging port assembly 240 is disposed at the opening of the bottom case 121, electrically connected to the battery 210 at one end, and used to connect to an external power source at the other end for supplying power to the battery 210. Specifically, the charging port assembly 240 can be set as a TYP-C port.

[0053] Among them, the housing 120 further includes a detachable waterproof cover 122. The waterproof cover 122 is disposed at the bottom opening of the housing 120 and on the outer surface of the bottom case 121. The waterproof cover 122 is used to prevent external water vapor from entering the charging port assembly 240 through the bottom opening of the housing 120.

[0054] In a specific embodiment of the present invention, the button pressure-sensing electric toothbrush further includes a brush head pressure sensor 140 disposed in the housing 120. The brush head pressure sensor 140 is connected to the control main board 220 and is used to detect the second pressure received by the toothbrush head 110. When the detected second pressure is greater than the second preset pressure value, a second start signal is sent to the control main board 220. The control main board 220 is further used to start up according to the first start signal, and drive the toothbrush head 110 to vibrate at the first vibration frequency when receiving the first trigger signal and the second start signal, so that the button pressure-sensing electric toothbrush enters the working mode. It can be understood that the second preset pressure value is the motor start pressure, and the second preset pressure value can be set by those skilled in the art according to the actual application situation, and this application does not make any restrictions.

[0055] Specifically, a receiving groove for accommodating the brush head pressure sensor 140 is provided on the side wall of the vibration rod 231. The brush head pressure sensor 140 is installed in the receiving groove, and the brush head pressure sensor 140 is electrically connected to the control main board 220. The brush head pressure sensor 140 detects the second pressure received by the toothbrush head 110 through the vibration rod 231, and sends the second start signal to the control main board 220 when the detected second pressure is greater than the second preset pressure value.

[0056] In the embodiment of the present utility model, the second pressure received by the toothbrush head is detected by the brush head pressure sensor 140, and a second start signal can be sent when it is detected that the second pressure is greater than the second preset pressure value, so that the button pressure sensing electric toothbrush enters the working mode only when receiving the first start signal, the second start signal and the first trigger signal. It is realized that when the user touches the control button 130 to turn on the machine, but the first pressure of the toothbrush head 110 does not exceed the second preset pressure value, that is, the start pressure value, the toothbrush head 110 does not vibrate, preventing water or toothpaste on the toothbrush head 110 from splashing due to vibration. Only when the toothbrush head 110 is placed in the oral cavity and the first pressure reaches the first preset pressure value, the button pressure sensing electric toothbrush enters the working mode.

[0057] In an optional manner, the brush head pressure sensor 140 is further configured to send a reminder signal to the control main board 220 when it is detected that the second pressure is greater than a third preset pressure value; the third preset pressure value is greater than the second preset pressure value; when the button pressure sensing electric toothbrush is in the working mode, the control main board 220 is further configured to drive the toothbrush head 110 to vibrate at a second vibration frequency according to the reminder signal, so that the button pressure sensing electric toothbrush enters the reminder mode; the second vibration frequency is less than the first vibration frequency. The third preset pressure value indicates that the toothbrush head 110 is in an overpressure state at this time, and the third preset pressure value can be set by those skilled in the art according to the actual situation. When the second pressure is greater than the third preset pressure value, it is determined that the toothbrush head 110 is in an overpressure state at this time. Excessive pressure plus the high-frequency sonic vibration friction of the bristles may cause damage to the teeth, such as harmful health problems such as gingival bleeding or dental wedge-shaped wear. Therefore, it is necessary to reduce the vibration frequency when the toothbrush head 110 is in an overpressure state.

[0058] Wherein, the button pressure sensing electric toothbrush further includes a reminder indicator light 141 disposed in the housing 120, and the reminder indicator light 141 is electrically connected to the control main board 220. When the button pressure sensing electric toothbrush is in the working mode, the control main board 220 is further configured to control the reminder indicator light 141 to light up according to the reminder signal; the housing 120 towards which the reminder indicator light 141 faces is made of a light-transmitting material.

[0059] In the embodiment of the present utility model, the button pressure-sensing electric toothbrush is provided with a third preset pressure value. When the button pressure-sensing electric toothbrush is in the working state, the second pressure of the toothbrush head 110 is also monitored in real time by the brush head pressure sensor 140. When it is detected that the second pressure is greater than the third preset pressure value, that is, when it is detected that the toothbrush head 110 is in an overpressure state, the vibration frequency of the toothbrush head 110 is adjusted to be less than that in the normal working mode to remind the user to stop the unhealthy brushing operation. In this way, the button pressure-sensing electric toothbrush provided by the embodiment of the present utility model has a pressure reminder and protection function, can correct the user's unhealthy brushing operation, and reduce the damage to the teeth.

[0060] Furthermore, in the embodiment of the present utility model, the reminder indicator light 141 also gives a pressure reminder to the user by emitting light when the toothbrush head 110 is in an overpressure state.

[0061] In a specific embodiment of the present utility model, the control main board 220 is provided with a main control chip, a touch-sensing chip, a sensor unit and a charging unit; the main control unit is used to obtain the first trigger signal of the touch-sensing chip, the first start signal and the second start signal of the sensor unit, and control the operation of the magnetic levitation motor 230; the charging unit is used to supply power to the control main board 220 and the magnetic levitation motor 230 through the battery 210.

[0062] Among them, the main control chip can adopt a chip of model SC8F2892B, and the touch-sensing chip adopts a chip of model RM1233AM; the Q pin of the touch-sensing chip is connected to the PWC4 / KEY4 / RB4 pin of the main control chip to transmit the first trigger signal to the main control chip; the I pin of the touch-sensing chip is connected to the conductive silica gel 151 to detect the touch signal of the human body through the conductive silica gel 151. The sensor unit includes a button pressure sensor 152, a brush head pressure sensor 140 and a sensor chip. The sensor chip can adopt a chip of model CSU18M68-QFN16-3X3. The sensor chip is electrically connected to the button pressure sensor 152 and the brush head pressure sensor 140 respectively, and is connected to the SDA pin of the main control chip through the SDA pin of the sensor chip to build a data transmission channel.
