Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

The embodiment of the application provides a handheld care device, which includes but is not limited to an electric toothbrush, a tooth cleaning device, a beauty instrument or other handheld care devices, and the embodiment of the application is not particularly limited to this, and the handheld care device is exemplified as an electric toothbrush.

Referring to fig. 1-3, an embodiment of the present application provides an electric toothbrush 1, the electric toothbrush 1 including a handle housing 10, a movement 20, and a brush head 30.

The handle housing 10 is adapted to be held by a user for the convenience of the user's use of the electric toothbrush 1, and the main body structure of the handle housing 10 may be made of plastic material, such as, but not limited to, hard plastic, such as polyethylene, polyester and other thermoplastics suitable for toothbrush manufacture, and the main body structure of the handle housing 10 may also be made of metal material, such as aluminum alloy, and the materials used for the main body structure of the handle housing 10 in the embodiments of the present application are not particularly limited.

The handle case 10 has a key part 11, and an installation space 10a is provided inside the handle case 10. The movement 20 is located in the installation space 10a so as to avoid the installation space 10a from being exposed to the outside of the electric toothbrush 1. The movement 20 includes a control board 22, a motor, a battery, a bracket 21, etc., the bracket 21 is used for supporting the control board 22, the motor, the battery, etc., the battery is used for supplying power to the control board 22 and the motor, the control board 22 can be used for controlling the motor to work, the motor can vibrate with different frequencies, the energy of the motor vibration can be transmitted to the brush head 30 through the output shaft 23, so as to realize the vibration of the brush head 30, and further realize the cleaning of the oral cavity of the user.

Referring to fig. 2-3, cartridge 30 further includes a first detecting member 40 and a second detecting member 50, and first detecting member 40 and second detecting member 50 are electrically connected to control board 22. The first detecting member 40 is used to detect the hand-held state of the handle case 10, that is, to detect whether the handle case 10 is held by hand. The first detecting member 40 may be provided at any position of the handle case 50,

The second detecting member 50 is for detecting the activation state of the key part 11, that is, for detecting whether the key part 11 is activated, and typically, when the key part 11 is activated, it indicates that the user wants to operate the electric toothbrush 1. The second detecting member 50 may be provided on the outer surface, the inner surface of the key part 11, the inside of the key part 11, or at a distance from the key part 11.

Further, one of the first detecting member 40 and the second detecting member 50 is a trigger member, and the other of the first detecting member 40 and the second detecting member 50 is a triggered member, that is, when the first detecting member 40 is a trigger member, the second detecting member 50 is a triggered member; when the second detecting member 50 is a triggering member, the first detecting member 40 is a triggered member, which is not particularly limited in the embodiment of the present application.

Further, the trigger piece is always in the detection state, and the triggered piece is switched to the detection state when the trigger piece generates a detection signal. For example, when the trigger member is the first detecting member 40, the first detecting member 40 is always in a detecting state to detect whether the handle housing 10 is held by the user, and when the handle housing 10 is held by the user, the first detecting member 40 generates a corresponding detecting signal and sends the detecting signal to the control board 22, so that the control board 22 can control the second detecting member 50 to switch to a detecting state according to the detecting signal, and at this time, both the first detecting member 40 and the second detecting member 50 are in a detecting state, that is, in a dual detecting state. At this time, the second detecting member 50 starts to detect whether the key portion 11 is activated, and when it is detected that the key portion 11 is activated, a corresponding detection signal is transmitted to the control board 22, and the control board 22 controls the electric toothbrush 1 to perform a corresponding operation, such as starting brushing teeth. It is understood that the first detecting member 40 may directly control the second detecting member 50 to switch to the detecting state without the control board 22 after generating the detecting signal.

For another example, when the triggering element is the second detecting element 50, the second detecting element 50 is always in a detecting state to detect whether the key portion 11 is triggered, and when the triggering of the key portion 11 is detected, the second detecting element 50 generates a corresponding detecting signal to send the detecting signal to the control board 22, so that the control board 22 can control the first detecting element 40 to switch to a detecting state according to the detecting signal, and at this time, both the first detecting element 40 and the second detecting element 50 are in a detecting state, that is, in a dual detecting state. At this time, the first detecting member 40 starts to detect whether the handle housing 10 is held, and when it is detected that the handle housing 10 is held, a corresponding detection signal is transmitted to the control board 22, and the control board 22 controls the electric toothbrush 1 to perform a corresponding operation, such as starting brushing teeth, or the like. It is understood that the second detecting member 50 may directly control the first detecting member 40 to switch to the detecting state without the control board 22 after generating the detecting signal.

Based on the above embodiments, the embodiments of the present application have at least the following two effects:

first, the probability of the electric toothbrush 1 being triggered can be reduced. Since the electric toothbrush 1 is triggered to perform the operation corresponding to the detection signal of the first detecting member 40 only when the first detecting member 40 detects that the handle housing 10 is held by hand and the second detecting member 50 detects that the key part 11 is pressed, the electric toothbrush 1 is prevented from being directly controlled to perform the corresponding operation when the key part 11 is pressed alone, and thus, the probability of the electric toothbrush 1 being erroneously triggered can be reduced. For example, when the button 11 is pressed by the mouth wall of the tooth glass, the handle case 10 is not held, and thus the electric toothbrush 1 is not triggered to perform the corresponding operation;

Second, the power consumption of the electric toothbrush can be reduced, and the standby time or the usable time of the electric toothbrush 1 can be prolonged on the premise of unchanged battery capacity. Since the second detecting member 50 is switched to the detecting state only when the first detecting member 40 generates the detecting signal, or the first detecting member 40 is switched to the detecting state only when the second detecting member 50 generates the detecting signal, when the handle case 10 is not held by the hand and the key portion 11 is not pressed, only one of the first detecting member 40 and the second detecting member 50 is always in the detecting state, and compared with the case where the first detecting member 40 and the second detecting member 50 are simultaneously in the detecting state, the power consumption of the electric toothbrush 1 in the standby state can be reduced.

Referring to fig. 3-4, since the trigger member is always in the detection state and the triggered member is switched to the detection state when the trigger member generates the detection signal, when the user triggers the trigger member, the trigger member can receive the trigger of the user and send the detection signal to the control board 22, the control board 22 controls the triggered member to switch to the detection state while receiving the detection signal, and when the triggered member is switched to the detection state, the electric toothbrush 1 is turned on in the dual detection state, and when the trigger member is not triggered by the user, the triggered member is not switched to the detection state, it can be understood that the electric toothbrush 1 needs to switch the triggered member to the detection state through the dual detection, so that the accuracy of switching the electric toothbrush 1 to the detection state can be improved, and the electric toothbrush 1 needs to switch to the detection state when the trigger member generates the detection signal, that is, the electric toothbrush 1 does not need to keep the detection state with high power consumption at all times, so that the duration of the electric toothbrush 1 can be prolonged.

Further, in order to ensure that the trigger piece is always in the detection state, the trigger piece is in the detection state may include, but not limited to, that the trigger piece is always on, or that the trigger piece is always in normal power consumption, or that the signal acquisition frequency of the trigger piece is greater than 0Hz, which is not specifically limited in the embodiment of the present application.

Meanwhile, the switching of the triggered element to the detection state may include, but is not limited to, switching the triggered element from off to on, or switching the triggered element from low power consumption to normal power consumption, or switching the signal acquisition frequency of the triggered element from low to high, and for example, when the switching of the triggered element to the detection state is that the signal acquisition frequency of the triggered element is controlled from low to high, at this time, the control board 22 receives the detection signal generated by the trigger element, and at the same time, the control board 22 also controls the signal acquisition frequency of the triggered element from low to high, so that the triggered element may switch to the detection state.

In some embodiments, the power of the trigger piece in the detection state is lower than the power of the triggered piece in the detection state, it can be understood that by setting such that the power of the trigger piece in the detection state is higher than the power of the trigger piece in the detection state even if the trigger piece is in the detection state, the trigger piece can be in the detection state on the premise of not consuming or consuming less electric power of the electric toothbrush 1, so that the trigger piece can detect whether the user needs to use the electric toothbrush 1 at any time, and when the trigger piece generates a detection signal, the triggered piece can be switched to the detection state to realize the dual detection state of the electric toothbrush 1, and when the trigger piece does not generate the detection signal, the triggered piece can not be switched to the detection state, so that, on one hand, the probability that the electric toothbrush 1 is triggered by the dual detection can be reduced, and on the other hand, because the trigger piece is in the detection state, the trigger piece can consume no or consume less electric power of the electric toothbrush 1, so that the power consumption of the electric toothbrush 1 is low, that is, the power consumption of the electric toothbrush 1 can be reduced, and the duration of the electric toothbrush 1 can be further prolonged.

Referring to fig. 2, in some embodiments, the key portion 11 is a seamless structure formed on the handle shell 10, that is, the key portion 11 may be integrally formed with the handle shell 10 through an injection molding process, so that the key portion 11 forms a seamless structure on the handle shell 10, and thus, a problem that a connecting seam exists between the key portion 11 and the handle shell 10 to cause dirt to be hidden at the connecting seam can be avoided, so that the key portion 11 plays a role in preventing water and dust, and meanwhile, when the key portion 11 is triggered by a user for a long time, because the key portion 11 forms a seamless structure on the handle shell 10, the problem that the key portion 11 is loosened or separated from the handle shell 10 due to long-term triggering of the key portion 11 can be avoided.

Further, since the key part 11 forms a seamless structure on the handle case 10, the first detecting piece 40 and the second detecting piece 50 can be provided near or inside the key part, and thus, the accuracy with which the electric toothbrush 1 is triggered can be improved.

In some embodiments, the first detecting member 40 may include at least one of a piezoelectric detecting member, a photoelectric detecting member, an acoustic wave detecting member, a temperature detecting member, and a motion detecting member, and the second detecting member 50 may include at least one of a piezoelectric detecting member, a photoelectric detecting member, an acoustic wave detecting member, a temperature detecting member, and a motion detecting member, where the first detecting member 40 and the second detecting member 50 may be of the same detecting type or of different types, and the embodiment of the present application is not specifically limited thereto, and when the second detecting member 50 is a piezoelectric detecting member, a user may press the key portion 11 to deform the key portion 11 by pressing the key portion 11, and the piezoelectric detecting member may detect whether the user triggers the key portion 11 by detecting the pressure deformation of the key portion 11.

When the second detecting element 50 is a photoelectric detecting element, the position of the key portion 11 has light transmittance, and when the hand of the user is placed on the key portion 11, the hand of the user can shield the position of the key portion 11, so that the photoelectric detecting element detects the luminous flux at the key, and whether the user triggers the key portion 11 is detected through the change of the actual luminous flux.

When the second detecting element 50 is an acoustic wave detecting element, the hand of the user is located at the position of the key portion 11 and reflects the acoustic wave signal sent by the acoustic wave detecting element, and the acoustic wave detecting element can detect whether the user triggers the key portion 11 by detecting the acoustic wave signal reflected at the key portion 11.

Referring to fig. 5, in some embodiments, the first detecting element 40 is used as a trigger element, the second detecting element 50 is used as a triggered element, where the first detecting element 40 is a trigger-responsive detecting element, and the first detecting element 40 is electrically connected to the control board 22, and the first detecting element 40 is configured to generate a detecting signal when triggered and responsive to the first detecting element 40, it may be understood that, when the first detecting element 40 is triggered and responsive to the first detecting element 40, the first detecting element 40 generates a relative detecting signal and sends the relative detecting signal to the control board 22, and the control board 22 controls the second detecting element 50 to switch to a detecting state according to the received detecting signal, so as to realize whether the second detecting element 50 detects the key portion 11 is triggered, and when the second detecting element 50 detects that the key portion 11 is triggered, the control board 22 may further control the electric toothbrush 1 to perform a corresponding operation according to the triggering condition of the key portion 11.

With continued reference to fig. 5, further, when the first detecting member 40 is not triggered but generates no detecting signal, that is, when the first detecting member 40 is not triggered by the user, the first detecting member 40 is in the detecting state but generates no detecting signal, and when the first detecting member 40 does not generate the detecting signal, the control board 22 does not control the second detecting member 50 to switch to the detecting state, that is, the second detecting member 50 does not detect whether the key portion 11 is in the triggered state at this time, and when the first detecting member 40 is in the detecting state, the power consumption rate of the electric toothbrush 1 by the first detecting member 40 is very low, even the electric quantity of the electric toothbrush 1 can not be consumed, so as to reduce the power consumption of the electric toothbrush 1, and thus, the electric quantity of the electric toothbrush 1 can be saved, and the endurance time of the electric toothbrush 1 can be further prolonged.

Referring to fig. 6-7, further, in some embodiments, the first detecting member 40 is a capacitive detecting member, the capacitive detecting member may include a capacitive sensor electrically connected to the control board 22, that is, when the first detecting member 40 is held by a user, the capacitive sensor may detect that the handle housing 10 is in a handheld state, so as to convert the variation detected that the handle housing 10 is in the handheld state into a capacitance, so as to form a detection signal, and the control board 22 may receive the detection signal, and determine whether the handle housing 10 is in the handheld state according to whether the detection signal is received.

Wherein, the capacitive sensor can be located the inboard of button portion 11, that is, the capacitive sensor can paste the internal surface of locating button portion 11, and when the user touches button portion 11, capacitive sensor can be used for detecting whether handle shell 10 is in handheld state, and because capacitive sensor pastes the internal surface of establishing at button portion 11, so capacitive sensor can be closer to button portion 11, so, can improve capacitive sensor's high efficiency and accuracy of detecting.

With continued reference to fig. 6-7, in some embodiments, the capacitive sensor includes a pair of conductors 41, where the conductors 41 are attached to the inner side of the key portion 11, that is, the capacitive sensor may be two conductors 41 that are disposed in pairs, and the two conductors 41 that are disposed in pairs are disposed at intervals along the circumferential or length direction A-A of the handle housing 10, and the conductors 41 that are disposed in pairs are turned on and generate a detection signal in response to being triggered, and it is understood that, since the capacitive sensor is electrically connected to the control board 22, the conductors 41 that are disposed in pairs are also electrically connected to the control board 22, and in order to ensure that the conductors 41 are always in a detection state, less electric power is required to be consumed when the conductors 41 that are disposed in pairs are connected to the control board 22, but since the handle housing 10 is not held, the conductors 41 that are disposed in pairs are in a detection state but are not turned on, and when the handle housing 10 is detected in a holding state, the conductors 41 that are disposed in pairs are turned on and generate a detection signal in response to being triggered, it is achieved that the first detection element 40 is electrically conductive and the first detection element 40 is always in a detection state when the electric toothbrush 1 is in a detection state.

With continued reference to fig. 6-7, in still other embodiments, two conductors 41 arranged in pairs are arranged at intervals to form a capacitive detection member, and a second detection member 50 is arranged between the two conductors 41, it can be understood that the first detection member 40 is two conductors 41 arranged in pairs, and the two conductors 41 arranged in pairs are arranged at intervals inside the key portion 11, and the second detection member 50 is arranged between the two conductors 41 arranged at intervals, at this time, the first detection member 40 and the second detection member 50 are both arranged inside the key portion 11, when the user holds the handle housing 10, the first detection member 40 can detect that the handle housing 10 is in a holding state, and because the second detection member 50 is arranged between the two conductors 41, the second detection member 50 is convenient to switch to a detection state when the first detection member 40 generates a detection signal, so as to realize that the second detection member 50 detects the triggering state of the key portion 11, and thus, whether the user needs to trigger the key more accurately.

Referring to fig. 7, further, in some embodiments, the second detecting member 50 is a pressure detecting member, and the pressure detecting member may include a wheatstone bridge piezoresistive sensor, and the wheatstone bridge piezoresistive sensor is attached to the inner side of the key portion 11.

Specifically, the wheatstone bridge piezoresistive sensor is configured to detect whether the key portion 11 is pressed, and when the key portion 11 is pressed, the key portion 11 is slightly deformed, so that the wheatstone bridge piezoresistive sensor can detect a change in resistance and form a certain voltage difference, the wheatstone bridge piezoresistive sensor can send the formed voltage difference signal to the control board 22, the control board 22 can amplify the voltage difference and convert the amplified voltage difference into a pressure value, and the control board 22 can control the electric toothbrush 1 to perform different operations according to the magnitude of the pressure value.

With continued reference to fig. 7, further, the wheatstone bridge piezoresistive sensor is attached to the inner side of the key portion 11, that is, the wheatstone bridge piezoresistive sensor is adhered to the inner surface of the key portion 11, so that the accuracy of detecting whether the key portion 11 is triggered can be improved.

The second detecting elements 50 may be adhered to the inner surface of the key portion 11, or the second detecting elements 50 may be disposed at intervals with the inner surface of the key portion 11, that is, the second detecting elements 50 may be disposed on the inner surface of the key portion 11 and connected to the inner surface of the key portion 11 by bonding, or the number of the second detecting elements 50 may be plural, and the second detecting elements 50 are disposed at intervals on the inner surface of the key portion 11.

Further, when the electric toothbrush 1 falls down carelessly to collide with the ground, the second detecting element 50 is attached to the inner surface of the button portion 11, so that the stability of the connection between the second detecting element 50 and the button portion 11 is improved, and thus, the second detecting element 50 is prevented from being separated from the button portion 11, and the detectability of the second detecting element 50 to the button portion 11 is prevented from being reduced.

Referring to fig. 8, in some embodiments, the second detecting member 50 is used as a trigger member, the first detecting member 40 is used as a triggered member, and when the detecting signal of the second detecting member 50 meets the first trigger condition, the first detecting member 40 is switched to the detecting state.

Specifically, when the second detecting member 50 is used as the triggering member, the electric toothbrush 1 may be in the flying mode at this time, and the user needs to trigger the button portion 11 of the second detecting member 50, that is, when the second detecting member 50 meets the first triggering condition, the second detecting member 50 may generate the detection signal, and the control board 22 controls the first detecting member 40 to switch to the detection state, that is, to detect whether the handle housing 10 is in the hand-held state, when the received detection signal,

further, in some embodiments, the second detecting member 50 controls the operation of the electric toothbrush 1 when the second triggering condition is satisfied, and the second triggering condition is different from the first triggering condition, it may be understood that, since the electric toothbrush 1 is in the flying mode at this time, when the user holds the handle housing 10, the first detecting member 40 cannot detect that the handle housing 10 is in the handheld state because it is the triggered member, and when the user can satisfy the first triggering condition by triggering the second detecting member 50, wherein the first triggering condition may be that the key part 11 is pressed for a long time, so that the electric toothbrush 1 is switched from the flying mode to the detecting mode.

When the electric toothbrush 1 is in the detection mode, at this time, the first detecting member 40 may be used to detect whether the handle case 10 is in a handheld state, and when the first detecting member 40 detects that the handle case 10 is in a handheld state, the control board 22 may control the electric toothbrush 1 to perform different operations according to the second detecting member 50 satisfying the second trigger condition, for example, when the second detecting member 50 detects that the key part 11 is pressed once, that is, the second trigger condition is a single press, the control board 22 may set an operation mode for controlling the electric toothbrush 1 to perform a single press according to a program of the single press of the electric toothbrush 1.

In some embodiments, the trigger is a trigger conduction type detection component, when the trigger is not triggered, the loop in which the trigger is located is not conductive and does not consume electricity, and it can be understood that when the trigger is a trigger conduction type detection component, the trigger needs to be triggered to conduct, that is, when the trigger detects that the handle shell 10 is in a handheld state or the key part 11 is in a trigger state, the loop in which the trigger is located can be in a closed conduction state, and when the trigger is not triggered, the loop in which the trigger is located is in an open non-conduction state, meanwhile, because the trigger is a trigger conduction type detection component at this time, when the trigger is not conductive, the loop in which the trigger is located does not consume electricity of the electric toothbrush 1 but the trigger can be in a detection state, that is, the trigger is still in a detection state under the condition of no electricity consumption, so that the electricity of the electric toothbrush 1 can be saved.

Further, in still other embodiments, the first detecting member 40, the second detecting member 50 and the control board 22 form a series detecting circuit, and the first detecting member 40 is a trigger conduction detecting member, and when the trigger generates a detecting signal, the series detecting circuit is conducted, so that the triggered member is switched to a detecting state.

Specifically, the first detecting element 40 and the second detecting element 50 may form a series detection circuit with the control board 22, when the triggering element generates a detection signal, the series detection circuit is turned on, that is, the first detecting element 40 and the second detecting element 50 are serially connected with the control board 22, when the first detecting element 40 detects that the handle shell 10 is in the handheld state, the first detecting element 40 may generate a detection signal and directly send the detection signal to the second detecting element 50, so that the second detecting element 50 is directly switched to the detection state without passing through the control board 22, and because the first detecting element 40 is the triggering conduction type detecting element, when the triggering element is not turned on, the triggering element may be in the detection state but does not consume the electric quantity of the electric toothbrush 1, so the electric quantity of the electric toothbrush 1 may be saved.

Referring to fig. 9, in some embodiments, the control board 22 may include a microcontroller 221 and a main controller 222, where the microcontroller 221 and the main controller 222 are both disposed in the handle shell 10, and the microcontroller 221 is electrically connected to the first detecting element 40 and the second detecting element 50, and the main controller 222 is electrically connected to the microcontroller 221, and it is understood that after the signals of the first detecting element 40 and the second detecting element 50 are sent to the microcontroller 221, the microcontroller 221 sends the signals of the first detecting element 40 and the second detecting element 50 to the main controller 222, and the main controller can control the electric toothbrush 1 to execute different signals according to the received signals of the first detecting element 40 and the second detecting element 50.

Referring to fig. 9-10, further, the microcontroller 221 is integrated with an analog-to-digital converter, for example, when the first detecting member 40 is a triggering member and the second detecting member 50 is a triggered member, the first detecting member 40 detects that the handle shell 10 is in a handheld state, and sends a detection signal generated by the first detecting member 40 to the microcontroller 221, so that a user wakes up the analog-to-digital converter on the microcontroller 221, and at the same time, the microcontroller 221 controls the second detecting member 50 to switch to a detection mode according to the detection signal, when the second detecting member 50 detects that the key portion 11 is in a triggering state, for example, when the second detecting member 50 is a pressure detecting member, the second detecting member 50 can detect that the key portion 11 is pressed, so that the key portion 11 is slightly deformed, and generates a voltage difference, the second detecting member 50 sends the voltage difference to the microcontroller 221 to perform amplification processing, and meanwhile, the analog-to-digital converter converts the amplified voltage difference into a pressure value, and when the pressure value is greater than the key triggering value, the microcontroller 221 can output a key signal and send to the main controller 222, and when the pressure value is greater than the key triggering value, the microcontroller 221 can control the electric toothbrush 1 to be turned on or turned off according to the key signal.

With continued reference to fig. 9-10, in still other embodiments, when the second detecting member 50 is a pressure detecting member, the second detecting member 50 may detect that the key portion 11 is pressed, so that the key portion 11 is slightly deformed and generates a voltage difference, the second detecting member 50 sends the voltage difference to the micro controller 221 for amplification, meanwhile, the analog-to-digital converter converts the amplified voltage difference into a pressure value, the pressure value may be transmitted to the main controller 222 through the serial bus, and the main controller 222 may control the electric toothbrush 1 to perform different operations according to the received pressure value, for example, when the user lightly presses the key portion 11, the pressure value received by the main controller 222 is smaller, so as to control the vibration frequency of the electric toothbrush 1 to be slower; when the user presses the key part 11 again, the pressure value received by the main controller 222 is larger to control the vibration frequency of the electric toothbrush 1 to be faster, that is, when the pressure value on the microcontroller 221 is transmitted to the main controller 222 through the serial bus, various modes of the electric toothbrush 1 can be realized, and thus, the experience of the user using the electric toothbrush 1 is improved.

When the key part 11 is formed in a seamless structure on the handle case 10, the key part 11 may be slightly deformed when the user presses the key part 11, but the deformation is difficult to be visually observed.

Referring to fig. 3 and 9, in some embodiments, the handle housing 10 further includes a light-transmitting portion 12 connected to the key portion 11, and it is understood that the key portion 11 may be connected to and spaced apart from the light-transmitting portion 12 in the length direction A-A of the electric toothbrush 1, and the key portion 11 may be disposed further away from the brush head 30 or closer to the brush head 30, which is not limited in the embodiments of the present application. Illustratively, when the key part 11 is disposed farther from the brush head 30, the light-transmitting part 12 is disposed closer to the brush head 30, and when the user cleans the oral cavity using the electric toothbrush 1, the key part 11 is disposed farther from the brush head 30, and the light-transmitting part 12 is disposed closer to the brush head 30, so that, on one hand, the user can conveniently hold the handle case 10 while pressing the key part 11, and on the other hand, according to the habit of holding the handle case 10 by the user, that is, the user holds the handle case 10 far from one end of the brush head 30, by disposing the light-transmitting part 12 closer to the brush head 30, the light-transmitting part 12 can be prevented from being blocked by the hand.

Referring to fig. 9, further, the electric toothbrush 1 further includes a display screen 60, the display screen 60 is disposed on the inner side of the light-transmitting portion 12, that is, the display screen 60 may be fixedly connected to the inner side of the light-transmitting portion 12, and in the radial direction of the handle shell 10, the display screen 60 is disposed opposite to the light-transmitting portion 12, and the display screen 60 is electrically connected to the microcontroller 221.

Specifically, since the display screen 60 is disposed opposite to the light-transmitting portion 12 and the light-transmitting portion 12 has light transmittance, the user can view information displayed on the display screen 60 through the light-transmitting portion 12. For example, during the use of the electric toothbrush 1, the electric toothbrush 1 may display the circuit of the electric toothbrush 1 or the current mode of the electric toothbrush 1 through the display screen 60, and the light transmitting portion 12 transmits the display information of the display screen 60, that is, the user may clearly know the electric quantity information of the electric toothbrush 1 or the current mode through the light transmitting portion 12, where the mode of the electric toothbrush 1 may include, but is not limited to, a whitening mode, a cleaning mode, a flying mode, etc., and it should be noted that, in the embodiment of the present application, the display information of the display screen 60 includes, but is not limited to, displaying the electric quantity information of the electric toothbrush 1 and the current mode.

The display screen 60 can be fixedly connected with the handle shell 10, it can be understood that the display screen 60 is installed on the inner side of the handle shell 10, instead of the prior art that the display screen 60 is installed on the movement 20 first, and then the display screen 60 is installed in the installation space 10a through the movement 20, the display screen 60 and the handle shell 10 can be fixedly connected, and therefore the display screen 60 can be prevented from being scratched by the handle shell 10.

The display screen 60 is electrically connected to the microcontroller 221, and the microcontroller 221 is electrically connected to the main controller 222, that is, when the user uses the electric toothbrush 1, the main controller 222 can send a display information signal to the microcontroller 221 under the control of the main controller 222, and the microcontroller 221 is electrically connected to the display screen 60, so that the microcontroller 221 can receive the display information signal sent by the main controller 222, and display the information content in the display information signal on the display screen 60, so that the user views the display information of the display screen 60 through the light-transmitting portion 12.

The microcontroller 221 may be disposed on the circuit board 90 or below the display screen 60, which is not particularly limited in this embodiment, and, for example, when the microcontroller 221 is disposed below the display screen 60, the first flexible circuit board 70 is electrically connected to the second flexible circuit board 80, and the second flexible circuit board 80 is electrically connected to the main controller 222, so that the first flexible circuit board 70 can be prevented from directly connecting with the main controller 222 on the circuit board 90, that is, the first flexible circuit board 70 is not required to connect with the main controller 222 on the circuit board 90, but the second flexible circuit board 80 is connected with the main controller 222 through the circuit board 90, so that the connection between the first flexible circuit board 70 and the circuit board 90 is reduced, and thus, the material preparation cost of the electric toothbrush 1 can be saved.
