Description

Handheld nursing devices Technical Field

[0001] The present application relates to the field of nursing technology, and in particular to a handheld nursing device. Background Art

[0002] In the related art, for handheld care devices, such as electric toothbrushes, water flossers, and beauty devices, taking electric toothbrushes as an example, users can control the electric toothbrush by pressing a button on the electric toothbrush. Specifically, when the user presses the button, the electric toothbrush can control the vibration motor according to the button signal to drive the brush head to vibrate.

[0003] However, for non-button handheld devices, corresponding detection sensors are usually provided to detect the operation the user wants to perform. For example, a pressure sensing acquisition module can be provided to detect the user's pressing force and thus obtain the operation the user wants to perform. However, if only a single or a single type of detection sensor is provided, there may be cases of false triggering. For example, when an electric toothbrush is placed in a mouthwash cup, the edge of the mouthwash cup applies a certain amount of pressure to the electric toothbrush. When this pressure is detected, even if the electric toothbrush is not being held, it will be triggered to perform the corresponding operation, which is a false triggering.

[0004] Summary of the Invention

[0005] An embodiment of the present application provides a handheld nursing device, which aims to improve the accuracy of triggering the handheld nursing device and reduce the probability of false triggering.

[0006] An embodiment of the present application provides a handheld nursing device, which includes a handle shell, a control panel, a first detection member and a second detection member. The handle shell has a button portion, and the control panel is arranged in the handle shell. The first detection member is configured to detect the handheld state of the handle shell, and the second detection member is configured to detect the triggering state of the button portion. One of the first detection member and the second detection member is a triggering member, and the other is a triggered member. The triggering member is always in a detection state, and the triggered member switches to a detection state when the triggering member generates a detection signal.

[0007] Furthermore, the power of the triggering component when it is in the detection state is lower than the power of the triggered component when it is in the detection state.

[0008] Furthermore, the trigger component being in the detection state all the time includes that the trigger component is always turned on, or that the trigger component is always in normal power consumption, or that the signal acquisition frequency of the trigger component is greater than 0 Hz.

[0009] Furthermore, the switching of the triggered component to the detection state includes controlling the triggered component to switch from off to on, or controlling the triggered component to switch from low power consumption to normal power consumption, or controlling the signal acquisition frequency of the triggered component from low to high.

[0010] Furthermore, the first detection element serves as the triggering element, and the second detection element serves as the triggered element. The first detection element is a trigger-responsive detection component and is electrically connected to the control board. The first detection element is configured to generate the detection signal when triggered to respond. When the first detection element is not triggered, it is in a detection state but does not generate the detection signal.

[0011] Furthermore, the first detection element is a capacitive detection element, and the capacitive detection element includes a capacitive sensor. The capacitive sensor is arranged on the inner side of the button portion and is electrically connected to the control board.

[0012] Furthermore, the capacitive sensor includes conductors arranged in pairs, which are attached to the inner side of the button part, and the two conductors arranged in pairs are spaced apart along the circumference or length direction of the handle shell. When the paired conductors are triggered, they are turned on and respond to generate the detection signal.

[0013] Furthermore, two conductors arranged in pairs are spaced apart to form the capacitive detection element, and the second detection element is arranged between the two conductors.

[0014] Furthermore, the second detection component is a pressure detection component, and the pressure detection component includes a Wheatstone bridge piezoresistive sensor, and the Wheatstone bridge piezoresistive sensor is attached to the inner side of the button portion.

[0015] Furthermore, the second detecting element serves as the triggering element, and the first detecting element serves as the triggered element. When the detection signal of the second detecting element satisfies a first triggering condition, the first detecting element switches to the detection state.

[0016] Furthermore, the second detection component controls the handheld nursing device to operate when a second trigger condition is met, and the second trigger condition is different from the first trigger condition.

[0017] Furthermore, the trigger component is a trigger conduction detection component. When the trigger component is not triggered, the circuit where the trigger component is located is not conductive and does not consume power.

[0018] Furthermore, the first detection element, the second detection element and the control board form a series detection circuit, and the first detection element is a trigger-conduction detection component, wherein when the trigger element generates the detection signal, the series detection circuit is turned on, so that the triggered element switches to the detection state.

[0019] Furthermore, the button portion is not formed as a seamless structure on the handle shell, and the second detection member is attached to the inner surface of the button portion or the second detection member is spaced apart from the inner surface of the button portion.

[0020] Furthermore, the first detection element includes at least one of a piezoelectric detection element, a photoelectric detection element, an acoustic wave detection element, a temperature detection element, and a motion detection element; and / or the second detection element includes at least one of a piezoelectric detection element, a photoelectric detection element, an acoustic wave detection element, a temperature detection element, and a motion detection element.

[0021] Furthermore, the control board includes a microcontroller and a main controller. The microcontroller is arranged in the handle shell, and the microcontroller is electrically connected to the first detection member and the second detection member. The main controller is arranged in the handle shell, and the main controller is electrically connected to the microcontroller.

[0022] Furthermore, the microcontroller is integrated with an analog-to-digital converter.

[0023] Furthermore, the handle shell also includes a light-transmitting portion connected to the button portion, and the handheld nursing device also includes a display screen, which is arranged on the inner side of the light-transmitting portion. In the radial direction of the handle shell, the display screen is arranged opposite to the light-transmitting portion and is electrically connected to the microcontroller.

[0024] Furthermore, the handheld nursing device also includes a first flexible circuit board and a second flexible circuit board. The first flexible circuit board is arranged in the handle shell and is electrically connected to the first detection member, the second detection member and the microcontroller. The second flexible circuit board is arranged in the handle shell and is electrically connected to the display screen, the first flexible circuit board and the main controller.

[0025] Furthermore, the handheld nursing device also includes a circuit board, which is arranged in the handle shell, the main controller is arranged on the circuit board, the second flexible circuit board is electrically connected to the main controller through the circuit board, and the microcontroller is arranged on the circuit board or under the display screen.

[0026] The present invention provides a handheld nursing device that has at least the following two effects:

[0027] First, the probability of the electric toothbrush being triggered can be reduced. Since the electric toothbrush is triggered to perform the operation corresponding to the detection signal of the first detection member only when the first detection member detects that the handle housing is being held and the second detection member detects that the button portion is being pressed, this avoids the situation where the electric toothbrush is directly controlled to perform the corresponding operation when the button portion is pressed alone. Therefore, the probability of the electric toothbrush being triggered by mistake can be reduced. For example, when the mouth wall of the mouthwash cup presses the button portion, since the handle housing is not being held, the electric toothbrush will not be triggered to perform the corresponding operation.

[0028] Secondly, the power consumption of the electric toothbrush can be reduced. Under the premise that the battery capacity remains unchanged, the standby time or usable time of the electric toothbrush can be extended. Since the second detection member switches to the detection state only when the first detection member generates a detection signal, or the first detection member switches to the detection state only when the second detection member generates a detection signal, when the handle shell is not held and the button portion is not pressed, only one of the first detection member and the second detection member is always in the detection state. Compared with the first detection member and the second detection member being in the detection state at the same time, the power consumption of the electric toothbrush in the standby state can be reduced.

DETAILED DESCRIPTION

[0041] The following will clearly and thoroughly describe the technical solutions in this application in conjunction with the accompanying drawings. In the description of the embodiments of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more than two.

[0042] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0043] An embodiment of the present application provides a handheld care device, which includes but is not limited to an electric toothbrush, an irrigator, a beauty instrument or other handheld care devices. The embodiment of the present application does not make specific limitations on this. The handheld care device is an electric toothbrush for example.

[0044] 1 to 3 , an embodiment of the present application provides an electric toothbrush 1 , which includes a handle housing 10 , a movement 20 , and a brush head 30 .

[0045] The handle shell 10 is suitable for being held by the user to facilitate the user to use the electric toothbrush 1. The main structure of the handle shell 10 can be made of plastic material, for example, it can include but is not limited to hard plastic, such as polyethylene, polyester and other thermoplastic plastics suitable for toothbrush manufacturing. The main structure of the handle shell 10 can also be made of metal material, such as aluminum alloy. The embodiment of the present application does not specifically limit the material used for the main structure of the handle shell 10.

[0046] The handle shell 10 has a button portion 11, and the interior of the handle shell 10 has an installation space 13. The movement 20 is located in the installation space 13 to prevent the installation space 13 from being exposed to the outside of the electric toothbrush 1. The movement 20 includes a control board 22, a motor, a battery, and a bracket 21. The bracket 21 is used to support components such as the control board 22, the motor, and the battery. The battery is used to power the control board 22 and the motor. The control board 22 can be used to control the operation of the motor, and the motor can vibrate at different frequencies. The energy of the motor vibration can be transmitted to the brush head 30 through the output shaft 23 to achieve vibration of the brush head 30, thereby cleaning the user's oral cavity.

[0047] Referring to Figures 2-3, the movement 30 further includes a first detection member 40 and a second detection member 50, which are electrically connected to the control board 22. The first detection member 40 is used to detect the holding state of the handle housing 10, that is, to detect whether the handle housing 10 is being held. The first detection member 40 can be disposed at any position on the handle housing 50.

[0048] The second detection member 50 is used to detect the triggering state of the button portion 11, that is, to detect whether the button portion 11 is triggered. Generally, when the button portion 11 is triggered, it indicates that the user wants to operate the electric toothbrush 1. The second detection member 50 can be provided on the outer surface, inner surface, or inside the button portion 11, or spaced apart from the button portion 11.

[0049] Furthermore, one of the first detection member 40 and the second detection member 50 is a triggering member, and the other of the first detection member 40 and the second detection member 50 is a triggered member, that is, when the first detection member 40 is a triggering member, the second detection member 50 is a triggered member; when the second detection member 50 is a triggering member, the first detection member 40 is a triggered member. The embodiment of the present application does not make specific limitations on this.

[0050] Furthermore, the triggering member is always in a detection state, and the triggered member switches to the detection state when the triggering member generates a detection signal. For example, when the triggering member is the first detection member 40, the first detection member 40 is always in a detection state to detect whether the handle shell 10 is held by the user. When the handle shell 10 is held by the user, the first detection member 40 generates a corresponding detection signal and sends the detection signal to the control board 22, so that the control board 22 can control the second detection member 50 to switch to the detection state according to the detection signal. At this time, the first detection member 40 and the second detection member 50 are both in the detection state, that is, in a dual detection state. At this time, the second detection member 50 begins to detect whether the button portion 11 is triggered. When it detects that the button portion 11 is triggered, it sends the corresponding detection signal to the control board 22. The control board 22 controls the electric toothbrush 1 to perform the corresponding operation, such as starting to brush teeth. It is understandable that after generating the detection signal, the first detection member 40 can also directly control the second detection member 50 to switch to the detection state without going through the control board 22.

[0051] For another example, when the triggering member is the second detection member 50, the second detection member 50 is always in a detection state to detect whether the button portion 11 is triggered. When the button portion 11 is detected to be triggered, the second detection member 50 generates a corresponding detection signal and sends it to the control board 22, so that the control board 22 can control the first detection member 40 to switch to the detection state according to the detection signal. At this time, the first detection member 40 and the second detection member 50 are both in the detection state, that is, in a dual detection state. At this time, the first detection member 40 begins to detect whether the handle shell 10 is held by hand. When it is detected that the handle shell 10 is held by hand, the corresponding detection signal is sent to the control board 22, and the control board 22 controls the electric toothbrush 1 to perform the corresponding operation, such as starting to brush teeth. It can be understood that after generating the detection signal, the second detection member 50 can also directly control the first detection member 40 to switch to the detection state without going through the control board 22.

[0052] Based on the above embodiments, the embodiments of the present application have at least the following two effects:

[0053] 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 detection member 40 only when the first detection member 40 detects that the handle shell 10 is being held and the second detection member 50 detects that the button portion 11 is being pressed, this avoids the situation where the electric toothbrush 1 is directly controlled to perform the corresponding operation when the button portion 11 is pressed alone. Therefore, the probability of the electric toothbrush 1 being mistakenly triggered can be reduced. For example, when the wall of the mouth of the mouthwash cup presses the button portion 11, since the handle shell 10 is not being held, the electric toothbrush 1 will not be triggered to perform the corresponding operation.

[0054] Secondly, the power consumption of the electric toothbrush can be reduced. Under the premise that the battery capacity remains unchanged, the standby time or usable time of the electric toothbrush 1 can be extended. Since the second detection member 50 will only switch to the detection state when the first detection member 40 generates a detection signal, or the first detection member 40 will only switch to the detection state when the second detection member 50 generates a detection signal, when the handle shell 10 is not held and the button portion 11 is not pressed, only one of the first detection member 40 and the second detection member 50 is always in the detection state. Compared with the first detection member 40 and the second detection member 50 being in the detection state at the same time, the power consumption of the electric toothbrush 1 in the standby state can be reduced.

[0055] Please refer to Figures 3-4. Since the triggering member is always in the detection state, and the triggered member switches to the detection state when the triggering member generates a detection signal, when the user triggers the triggering member, the triggering member can receive the user's trigger and send a 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 switches to the detection state, the electric toothbrush 1 turns on the dual detection state. When the triggering member is not triggered by the user, the triggered member will not switch to the detection state. It can be understood that the electric toothbrush 1 needs to pass the dual detection before the triggered member can be switched to the detection state. In this way, the accuracy of the electric toothbrush 1 switching to the detection state can be improved, and the electric toothbrush 1 needs the triggered member to switch to the detection state when the triggering member generates a detection signal. That is, the electric toothbrush 1 does not need to maintain a high-power consumption detection state at all times to reduce the power consumption of the electric toothbrush 1. In this way, the battery life of the electric toothbrush 1 can be extended.

[0056] Furthermore, in order to ensure that the trigger component is always in the detection state, the trigger component in the detection state may include but is not limited to the trigger component being always turned on, or the trigger component is always in normal power consumption, or the signal acquisition frequency of the trigger component is greater than 0Hz. The embodiments of the present application do not make specific limitations on this.

[0057] At the same time, the triggered component switching to the detection state may include but is not limited to controlling the triggered component to switch from off to on, or controlling the triggered component to switch from low power consumption to normal power consumption, or controlling the signal acquisition frequency of the triggered component from low to high. For example, when the triggered component switches to the detection state to control the signal acquisition frequency of the triggered component from low to high, at this time, while the control board 22 receives the detection signal generated by the triggering component, the control board 22 also controls the signal acquisition frequency of the triggered component from low to high, so that the triggered component can switch to the detection state.

[0058] In some embodiments, the power of the triggering member when it is in the detection state is lower than the power of the triggered member when it is in the detection state. It can be understood that the power of the triggered member when it is in the detection state can be set so that even if the triggering member is in the detection state, the power of the triggered member when it is in the detection state is still higher than the power of the triggering member when it is in the detection state. In this way, the triggering member can be in the detection state without consuming or consuming less power of the electric toothbrush 1, so that the triggering member can always detect whether the user needs to use the electric toothbrush 1, and when the triggering member generates a detection signal, the triggered member can switch to the detection state to achieve a dual detection state of the electric toothbrush 1. When the triggering member does not generate a detection signal, the triggered member will not switch to the detection state. In this way, on the one hand, the electric toothbrush 1 can reduce the probability of being triggered by the dual detection. On the other hand, since the triggering member can consume no or less power of the electric toothbrush 1 when it is in the detection state, the power consumption of the electric toothbrush 1 is low, that is, the power consumption of the electric toothbrush 1 can be reduced, thereby extending the battery life of the electric toothbrush 1.

[0059] Please refer to Figure 2. In some embodiments, the button part 11 is a seamless structure formed on the handle shell 10, that is, the button part 11 can be formed into one piece with the handle shell 10 through an injection molding process, so that the button part 11 forms a seamless structure on the handle shell 10. In this way, the existence of a connection seam between the button part 11 and the handle shell 10 can be avoided, which causes the problem of dirt and grime accumulating at the connection seam, thereby making the button part 11 waterproof and dustproof. At the same time, when the button part 11 is triggered by the user for a long time, since the button part 11 forms a seamless structure on the handle shell 10, the problem of the button part 11 loosening or detaching from the handle shell 10 due to being triggered by the user for a long time can be avoided.

[0060] Furthermore, since the button portion 11 forms a seamless structure on the handle shell 10, the first detection member 40 and the second detection member 50 can be arranged near or inside the button portion, thereby improving the accuracy of triggering the electric toothbrush 1.

[0061] In some embodiments, the first detection element 40 may include at least one of a piezoelectric detection element, a photoelectric detection element, an acoustic wave detection element, a temperature detection element, and a motion detection element, and the second detection element 50 may include at least one of a piezoelectric detection element, a photoelectric detection element, an acoustic wave detection element, a temperature detection element, and a motion detection element, wherein the first detection element 40 and the second detection element 50 may be of the same detection type or of different types, and the embodiments of the present application do not specifically limit this. For example, when the second detection element 50 is a piezoelectric detection element, the user can press the button portion 11 to cause pressure deformation of the button portion 11, and the piezoelectric detection element can detect whether the user has triggered the button portion 11 by detecting the pressure deformation of the button portion 11.

[0062] When the second detection element 50 is a photoelectric detection element, the position where the button part 11 is located is light-transmissive. When the user's hand is placed on the button part 11, the user's hand can block the position of the button part 11, so that the photoelectric detection element detects the luminous flux at the button, and detects whether the user triggers the button part 11 through the change in the actual luminous flux.

[0063] When the second detection component 50 is an acoustic wave detection component, the user's hand is located at the position of the button part 11 and reflects the acoustic wave signal emitted by the acoustic wave detection component. The acoustic wave detection component can detect whether the user triggers the button part 11 by detecting the acoustic wave signal reflected at the button part 11.

[0064] Please refer to Figure 5. In some embodiments, the first detection member 40 serves as a triggering member and the second detection member 50 serves as a triggered member, wherein the first detection member 40 is a trigger-responsive detection component, and the first detection member 40 is electrically connected to the control board 22. The first detection member 40 is configured to generate a detection signal when it is triggered in response. It can be understood that when the first detection member 40 is triggered in response, the first detection member 40 will generate a relative detection signal and send it to the control board 22. The control board 22 controls the second detection member 50 to switch to the detection state according to the received detection signal, so that the second detection member 50 detects whether the button part 11 is triggered. When the second detection member 50 detects that the button part 11 is triggered, the control board 22 can also control the electric toothbrush 1 to perform corresponding operations according to the triggering status of the button part 11.

[0065] Please continue to refer to Figure 5. Furthermore, when the first detection member 40 is not triggered, it is in the detection state but does not generate a detection signal, that is, when the first detection member 40 is not triggered by the user, the first detection member 40 is in the detection state but does not generate a detection signal. When the first detection member 40 does not generate a detection signal, the control board 22 will not control the second detection member 50 to switch to the detection state, that is, the second detection member 50 will not detect whether the button part 11 is in the triggered state at this time, and when the first detection member 40 is in the detection state, the first detection member 40 has an extremely low power consumption rate for the electric toothbrush 1, and may even not consume the power of the electric toothbrush 1, so as to reduce the power consumption of the electric toothbrush 1. In this way, the power of the electric toothbrush 1 can be saved, thereby extending the battery life of the electric toothbrush 1.

[0066] Please refer to Figures 6-7. Further, in some embodiments, the first detection member 40 is a capacitive detection member, which may include a capacitive sensor. The capacitive sensor is electrically connected to the control board 22. That is, when the first detection member 40 is held by the user, the capacitive sensor can detect that the handle shell 10 is in a hand-held state, so as to convert the change in the amount of detection of the handle shell 10 being in the hand-held state into capacitance to form a detection signal, and the control board 22 can receive the detection signal and determine whether the handle shell 10 is in a hand-held state based on whether the detection signal is received.

[0067] Among them, the capacitive sensor can be arranged on the inner side of the button part 11, that is, the capacitive sensor can be attached to the inner surface of the button part 11. When the user touches the button part 11, the capacitive sensor can be used to detect whether the handle shell 10 is in a handheld state. And because the capacitive sensor is attached to the inner surface of the button part 11, the capacitive sensor can be closer to the button part 11, so that the efficiency and accuracy of the capacitive sensor detection can be improved.

[0068] Please continue to refer to Figures 6-7. Further, in some embodiments, the capacitive sensor includes conductors 41 arranged in pairs, and the conductors 41 are attached to the inner side of the button portion 11. That is, the capacitive sensor can be two conductors 41 arranged in pairs, and the two conductors 41 arranged in pairs are arranged at intervals along the circumference or length direction AA of the handle shell 10. When the paired conductors 41 are triggered, they are turned on and respond to generate a detection signal. It can be understood that since the capacitive sensor is electrically connected to the control board 22, the paired conductors 41 are also electrically connected to the control board 22. , and in order to ensure that the conductor 41 is always in the detection state, the paired conductors 41 need to consume less power of the electric toothbrush 1 when connected to the control board 22 at this time. However, since the handle shell 10 is not held by hand, the paired conductors 41 are in the detection state but are not conductive. When the paired conductors 41 detect that the handle shell 10 is in the hand-held state, the paired conductors 41 are conductive and respond to generate a detection signal. In this way, the first detection component 40 can be realized while consuming less power of the electric toothbrush 1, so that the first detection component 40 is always in the detection state.

[0069] Please continue to refer to Figures 6 and 7. In some other embodiments, two conductors 41 arranged in pairs are spaced apart to form a capacitive detection element, and the second detection element 50 is arranged between the two conductors 41. It can be understood that the first detection element 40 is two conductors 41 arranged in pairs, and the two paired conductors 41 are spaced apart on the inner side of the button portion 11, and the second detection element 50 is arranged between the two spaced apart conductors 41. At this time, the first detection element 40 and the second detection element 50 are both arranged on the inner side of the button portion 11. When the user holds the handle shell 10, the first detection element 40 can detect that the handle shell 10 is in a hand-held state, and because the second detection element 50 is arranged between the two conductors 41, it is convenient for the second detection element 50 to switch to the detection state when the first detection element 40 generates a detection signal, so as to realize the second detection element 50 detecting the trigger state of the button portion 11. In this way, it is possible to more accurately detect whether the user needs to trigger the button.

[0070] Please refer to FIG. 7 . Furthermore, in some embodiments, the second detecting element 50 is a pressure detecting element. The pressure detecting element may include a Wheatstone bridge piezoresistive sensor. The Wheatstone bridge piezoresistive sensor is attached to the inner side of the button portion 11 .

[0071] Specifically, the Wheatstone bridge piezoresistive sensor is used to detect whether the button portion 11 is pressed. When the button portion 11 is pressed, the button portion 11 will undergo a slight deformation, so that the Wheatstone bridge piezoresistive sensor can detect the 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 it into a pressure value. The control board 22 can control the electric toothbrush 1 to perform different tasks according to the size of the pressure value.

[0072] Please continue to refer to Figure 7. Furthermore, the Wheatstone bridge piezoresistive sensor is attached to the inner side of the button portion 11, that is, the Wheatstone bridge piezoresistive sensor is adhered to the inner surface of the button portion 11. In this way, the accuracy of detecting whether the button portion 11 is triggered can be improved.

[0073] The second detection member 50 can be attached to the inner surface of the button part 11, or the second detection member 50 is spaced apart from the inner surface of the button part 11, that is, the second detection member 50 can be provided on the inner surface of the button part 11 and connected to the inner surface of the button part 11 by bonding, or the number of the second detection members 50 can be multiple, and the second detection members 50 are spaced apart on the inner surface of the button part 11. When the user needs to trigger the button part 11, since the second detection member 50 is attached to the inner surface of the button part 11, the second detection member 50 can be closer to the button part 11. In this way, the accuracy of the second detection member 50 in detecting whether the button part 11 is triggered can be improved.

[0074] Furthermore, when the electric toothbrush 1 accidentally falls and collides with the ground, the second detection member 50 is attached to the inner surface of the button portion 11, so that the stability of the connection between the second detection member 50 and the button portion 11 is improved. In this way, the second detection member 50 can be prevented from being separated from the button portion 11, which would cause the second detection member 50 to reduce the detectability of the button portion 11.

[0075] Please refer to FIG8 . In some embodiments, the second detecting element 50 serves as a triggering element, and the first detecting element 40 serves as a triggered element. When the detection signal of the second detecting element 50 satisfies a first triggering condition, the first detecting element 40 switches to a detection state.

[0076] Specifically, when the second detection member 50 acts as a trigger, the electric toothbrush 1 can be in flight mode at this time. The user needs to trigger the button part 11 of the second detection member 50, that is, the second detection member 50 can generate a detection signal when it meets the first trigger condition. When the control panel 22 receives the detection signal, it controls the first detection member 40 to switch to the detection state, that is, to detect whether the handle shell 10 is in a handheld state.

[0077] Furthermore, in some embodiments, the second detection member 50 controls the operation of the electric toothbrush 1 when the second trigger condition is met, and the second trigger condition is different from the first trigger condition. It can be understood that since the electric toothbrush 1 is in flight mode at this time, when the user holds the handle shell 10, the first detection member 40 cannot detect that the handle shell 10 is in a handheld state because it is a triggered member. The user can trigger the second detection member 50 to meet the first trigger condition, wherein the first trigger condition can be by long pressing the button part 11 to switch the electric toothbrush 1 from flight mode to detection mode.

[0078] When the electric toothbrush 1 is in the detection mode, at this time, the first detection member 40 can be used to detect whether the handle shell 10 is in a hand-held state. When the first detection member 40 detects that the handle shell 10 is in a hand-held state, the control panel 22 can control the electric toothbrush 1 to perform different tasks when the second detection member 50 meets the second trigger condition. For example, when the second detection member 50 detects that the button part 11 is pressed once, that is, the second trigger condition is a single press, the control panel 22 can control the electric toothbrush 1 to perform a single-press working mode according to the program setting of the electric toothbrush 1 being pressed once.

[0079] In some embodiments, the trigger is a trigger-conduction detection component. When the trigger is not triggered, the circuit where the trigger is located is not conductive and does not consume power. It can be understood that when the trigger is a trigger-conduction detection component, the trigger needs to be triggered before it can be conductive, that is, when the trigger detects that the handle shell 10 is in a handheld state or the button part 11 is in a triggered state, the circuit where the trigger is located can be in a closed conductive state, and when the trigger is not triggered, the circuit where the trigger is located is in an open circuit and non-conductive state. At the same time, since the trigger is a trigger-conduction detection component at this time, when the trigger is not conductive, the circuit where the trigger is located will not consume the power of the electric toothbrush 1, but the trigger can be in a detection state, that is, when the electric toothbrush 1 does not consume power, the trigger is still in a detection state. In this way, the power of the electric toothbrush 1 can be saved.

[0080] Furthermore, in some other embodiments, the first detection element 40, the second detection element 50 and the control board 22 form a series detection circuit, and at this time the first detection element 40 is a trigger-conduction detection component. When the trigger element generates a detection signal, the series detection circuit is turned on, so that the triggered element switches to the detection state.

[0081] Specifically, the first detection member 40 and the second detection member 50 can form a series detection circuit with the control board 22. When the trigger member generates a detection signal, the series detection circuit is turned on, that is, the first detection member 40, the second detection member 50 and the control board 22 are turned on in series. When the first detection member 40 detects that the handle shell 10 is in a handheld state, the first detection member 40 can generate a detection signal and send the detection signal directly to the second detection member 50, so that the second detection member 50 can directly switch to the detection state without passing through the control board 22. Since the first detection member 40 is a trigger-conducting detection component, when the trigger member is not turned on, the trigger member can be in the detection state but does not consume the power of the electric toothbrush 1. In this way, the power of the electric toothbrush 1 can be saved.

[0082] Please refer to Figure 9. In some embodiments, the control board 22 may include a microcontroller 221 and a main controller 222. The microcontroller and the main controller 222 are both arranged in the handle shell 10. The microcontroller 221 is electrically connected to the first detection member 40 and the second detection member 50. The main controller 222 is electrically connected to the microcontroller 221. It can be understood that the signals of the first detection member 40 and the second detection member 50 are first sent to the microcontroller 221, and the microcontroller 221 then sends the signals of the first detection member 40 and the second detection member 50 to the main controller 222. The main controller 222 can control the electric toothbrush 1 to execute different signals based on the received signals of the first detection member 40 and the second detection member 50.

[0083] Please refer to Figures 9-10. Further, the microcontroller 221 is integrated with an analog-to-digital converter. For example, when the first detection member 40 is a triggering member and the second detection member 50 is a triggered member, the first detection member 40 detects that the handle shell 10 is in a handheld state, and sends the detection signal generated by the first detection member 40 to the microcontroller 221 so that the user wakes up the analog-to-digital converter on the microcontroller 221. At the same time, the microcontroller 221 also controls the second detection member 50 to switch to the detection mode according to the detection signal. When the second detection member 50 detects that the button portion 11 is in a triggering state, for example, the first detection member 40 detects that the handle shell 10 is in a handheld state. When the second detection member 50 is a pressure detection member, the second detection member 50 can detect the pressing of the button part 11, so that the button part 11 is slightly deformed and a voltage difference is generated. The second detection member 50 sends the voltage difference to the microcontroller 221 for amplification. At the same time, the analog-to-digital converter converts the amplified voltage difference into a pressure value, and the microcontroller 221 is provided with a button trigger value. When the pressure value is greater than the button trigger value, the microcontroller 221 can output a button signal and send it to the main controller 222. The main controller 222 controls the opening or closing of the electric toothbrush 1 according to the received button signal.

[0084] Please continue to refer to Figures 9 and 10. Furthermore, in some other embodiments, when the second detection member 50 is a pressure detection member, the second detection member 50 can detect that the button portion 11 is pressed, so that the button portion 11 is slightly deformed and a voltage difference is generated. The second detection member 50 sends the voltage difference to the microcontroller 221 for amplification. At the same time, the analog-to-digital converter converts the amplified voltage difference into a pressure value, which can be transmitted to the main controller 222 via the serial bus. The main controller 222 can control the electric toothbrush 1 to perform different operations according to the size of the received pressure value. For example, when the user presses the button portion 11 lightly, 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 button portion 11 hard, the pressure value received by the main controller 222 is larger, so as 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 via the serial bus, multiple modes of the electric toothbrush 1 can be realized, thereby improving the user's experience of using the electric toothbrush 1.

[0085] It should be noted that when the button portion 11 forms a seamless structure on the handle shell 10 , the button portion 11 may be slightly deformed when the user presses the button portion 11 , but the deformation is difficult to be seen with the naked eye.

[0086] Referring to FIG3 and FIG9 , in some embodiments, the handle housing 10 further includes a light-transmitting portion 12 connected to the button portion 11. It is understood that in the longitudinal direction AA of the electric toothbrush 1, the button portion 11 can be connected to the light-transmitting portion 12 and spaced apart, and the button portion 11 can be located further away from the brush head 30 or closer to the brush head 30. This is not limited in the present application. For example, when the button portion 11 is located further away from the brush head 30, the light-transmitting portion 12 is located closer to the brush head 30. When the user uses the electric toothbrush 1 to clean the oral cavity, the button portion 11 is located further away from the brush head 30, while the light-transmitting portion 12 is located closer to the brush head 30. This, on the one hand, makes it easier for the user to press the button portion 11 while holding the handle housing 10. On the other hand, according to the user's habit of holding the handle housing 10, that is, the user holds the handle housing 10 at the end away from the brush head 30, by arranging the light-transmitting portion 12 closer to the brush head 30, the light-transmitting portion 12 can be prevented from being blocked by the hand.

[0087] Please refer to Figure 9. Furthermore, the electric toothbrush 1 also includes a display screen 60, which is arranged on the inner side of the light-transmitting portion 12. That is, the display screen 60 can be fixedly connected to the inner side of the light-transmitting portion 12. In the radial direction of the handle shell 10, the display screen 60 and the light-transmitting portion 12 are arranged opposite to each other, and the display screen 60 is electrically connected to the microcontroller 221.

[0088] Specifically, because the display screen 60 is arranged opposite to the light-transmitting portion 12, and the light-transmitting portion 12 is light-transmitting, the user can view the 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 can 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 can clearly know the power information of the electric toothbrush 1 or the current mode it is in through the light-transmitting portion 12, wherein the mode of the electric toothbrush 1 may include but is not limited to whitening mode, cleaning mode, flight mode, etc. It should be noted that the display information of the display screen 60 in the embodiment of the present application includes but is not limited to displaying the power information of the electric toothbrush 1 and the current mode it is in.

[0089] The display screen 60 can be fixedly connected to 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 first installing the display screen 60 on the movement 20 and then installing the display screen 60 into the installation space 13 through the movement 20 as in the prior art. The embodiment of the present application can fix the display screen 60 to the handle shell 10, so that the display screen 60 can be prevented from being scratched by the handle shell 10.

[0090] Among them, 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, under the control of the main controller 222, the main controller 222 can send a display information signal to the microcontroller 221, 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 can view the display information of the display screen 60 through the light-transmitting portion 12.

[0091] Please continue to refer to Figure 9. Further, in some embodiments, the electric toothbrush 1 also includes a first flexible circuit board 70 and a second flexible circuit board 80. The first flexible circuit board 70 and the second flexible circuit board 80 are both arranged in the handle shell 10, wherein the first flexible circuit board 70 is electrically connected to the first detection member 40, the second detection member 50 and the microcontroller 221, and the second flexible circuit board 80 is electrically connected to the display screen 60, the first flexible circuit board 70 and the main controller 222. It can be understood that the first detection member 40, the second detection member 50 and the microcontroller 221 can be arranged on the first flexible circuit board 70, and the display screen 60 is arranged on the second flexible circuit board 80, wherein the first flexible circuit board 70 can be electrically connected to the main controller 222 by zero insertion force. In the embodiment of the present invention, a ZIF (ZiF) connector (not shown) is used to connect the first detecting member 40, the second detecting member 50 and the signal lines of the microcontroller 221 to the second flexible circuit board 80, and then the signal lines of the first detecting member 40, the second detecting member 50, the microcontroller 221 and the display screen 60 are electrically connected to the main controller 222. In this way, the signal lines of the first detecting member 40, the second detecting member 50, the microcontroller 221 and the display screen 60 can be connected more neatly.

[0092] Please continue to refer to Figure 9. Furthermore, in some embodiments, the electric toothbrush 1 also includes a circuit board 90, which is disposed in the handle shell 10, that is, the circuit board 90 can be disposed in the installation space 13, the main controller 222 is disposed on the circuit board 90, the second flexible circuit board 80 is electrically connected to the main controller 222 through the circuit board 90, the microcontroller 221 is disposed on the circuit board 90, or the microcontroller 221 is disposed below the display screen 60.

[0093] Specifically, the circuit board 90 can be used to support the main controller 222. The circuit board 90 is disposed within the handle housing 10, thereby preventing the main controller 222 from being exposed to the outside of the electric toothbrush 1 and protecting the main controller 222. The microcontroller 221 can be disposed on the circuit board 90 or below the display screen 60. This is not specifically limited in the present embodiment. For example, when the microcontroller 221 is disposed below the display screen 60, since 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, it is possible to avoid direct wiring between the first flexible circuit board 70 and the main controller 222 on the circuit board 90. That is, there is no need for the first flexible circuit board 70 to be wired to the main controller 222 on the circuit board 90. Instead, the second flexible circuit board 80 is wired to the main controller 222 through the circuit board 90, thereby reducing the wiring between the first flexible circuit board 70 and the circuit board 90. In this way, the material preparation cost of the electric toothbrush 1 can be reduced.
