[0043] The utility model provides an electric toothbrush, Figures 1 to 4As shown, it includes: a handle 1, the handle 1 includes a shell 2, a first button 201, a second button 202, a detection chip, a control chip, multiple actuators and at least one power supply; wherein the power supply is electrically connected to the first button 201, the second button 202, the detection chip, the control chip and the multiple actuators respectively; a cavity is provided in the shell 2, the detection chip and the control chip are communicatively connected and are both arranged in the cavity; multiple actuators are respectively connected to the control chip and are respectively arranged on the shell 2 and / or in the cavity; the first button 201 and the second button 202 are arranged on the shell 2 and are respectively connected to the detection chip; when the first button 201 and the second button 202 obtain the first pressure value and / or the second pressure value, the detection chip compares the first pressure value with the second pressure value, and / or compares the first pressure value and the second pressure value with a preset pressure threshold, and sends the comparison result and the first pressure value and / or the second pressure value to the control chip, and the control chip controls the start / stop of each actuator and / or part of the actuator according to the comparison result and the first pressure value and / or the second pressure value.

[0044] Specifically, various components supporting the operation of the electric toothbrush are disposed on or within the handle 1. When using the electric toothbrush, the electric toothbrush is operated by gripping the handle 1. The handle 1 includes a housing 2, a first button 201, a second button 202, a detection chip, a control chip, multiple actuators, and at least one power supply. The shell 2 is the main part of the electric toothbrush, which is used to hold or support the installation of various components; the first button 201 and the second button 202 are respectively used to obtain the first pressure value and the second pressure value when the user uses the electric toothbrush. It should be noted that the first pressure value and the second pressure value described here can be generated by the user's same finger pressing the first button 201 and the second button 202 at the same time, or by two different fingers pressing the first button 201 and the second button respectively to generate the first pressure value and the second pressure value; the detection chip is used to compare the first pressure value and the second pressure value to determine the size relationship between the first pressure value and the second pressure value; the control chip is used to control the start / stop of each actuator or part of the actuator according to the comparison result; the power supply is used to power the first button 201, the second button 202, the detection chip, the control chip and multiple actuators.

[0045] In this embodiment, the power supply is electrically connected to the first button 201, the second button 202, the detection chip, the control chip and the multiple actuators, respectively, to supply power to them so that they can operate normally and work. A cavity is provided in the housing 2 of the electric toothbrush, and the detection chip and the control chip are communicatively connected to realize the transmission of the first pressure value, the second pressure value and the comparison result. At the same time, the detection chip and the control chip are simultaneously arranged in the cavity of the housing 2. The control chip controls and connects multiple actuators respectively to realize individual control of each actuator through the comparison result and the first pressure value and / or the second pressure value. At the same time, multiple actuators can be arranged in the cavity, some of which are arranged in the cavity and the other part are arranged on the housing 2. The actuator arranged in the cavity is, for example, a power element (motor), and the actuator arranged on the housing 2 is, for example, an indicator light. The first button 201 and the second button 202 are arranged on the housing 2 and connected to the detection chip. It should be noted that the connections in the above description include but are not limited to wired or wireless connections.

[0046] It should be noted that, in this embodiment, for example, the first pressure value and the second pressure value generated by the first button 201 and the second button 202 are generated by the same finger of the user, that is, the first button 201 and the second button 202 are adjacently arranged on the housing 2. For example, when the user presses the first button 201 and the second button 202 with the thumb, the first button 201 corresponds to the center position of the user's thumb, and the second button 202 corresponds to the edge position of the center position of the user's thumb. Obviously, due to the shape and characteristics of people's fingers, when the user presses the first button 201 and the second button 202 with the thumb, the pressure generated by the center position of the thumb is significantly greater than the pressure generated by the edge position of the center position of the thumb. Therefore, when the first pressure value is greater than the second pressure value, it is judged that the user is operating the electric toothbrush through the first button 201 and the second button 202, and the user's control of the electric toothbrush through the first button 201 and the second button 202 will be executed. It should also be noted that, in this embodiment, since the electric toothbrush itself is controlled by the first button 201 and the second button 202, the first pressure value and the second pressure value generated by the first button 201 and the second button 202 contain control signals for the electric toothbrush, or the first pressure value and the second pressure value themselves are control signals for the electric toothbrush. It should also be noted that, for aesthetic purposes, only one button area can be provided on the housing 2 of the electric toothbrush, so that the first button 201 is provided at the center of the button area and the second button 202 is provided at the edge of the button area. When the user presses the button area, the center of the user's finger corresponds to the center of the button area, i.e., the first button 201, and the edge of the user's finger corresponds to the edge of the button area, i.e., the second button 202, to enhance the aesthetics of the electric toothbrush.

[0047] In this embodiment, the electric toothbrush is controlled by two buttons, which prevents the brushing mode of the electric toothbrush from being adjusted by accidental touch when using the electric toothbrush, and improves the stability of the electric toothbrush and the experience of using the electric toothbrush. In addition, it prevents accidental touch when transporting or cleaning the electric toothbrush, prevents power consumption of the power supply, improves the battery life of the electric toothbrush, and reduces the charging frequency of the power supply, thereby improving the service life of the power supply and the electric toothbrush.

[0048] Furthermore, the first button 201 and the second button 202 are both pressure-sensing buttons, and each pressure-sensing button is provided with at least one pressure sensor.

[0049] In this embodiment, the first button 201 and the second button 202 are both pressure sensing buttons for controlling the electric toothbrush. The pressure sensing buttons include at least one pressure sensor.

[0050] In this embodiment, two pressure-sensitive sensors are used to detect pressure. Compared with detecting capacitance through a capacitive sensor, the pressure-sensitive sensor used in this solution has higher detection accuracy and higher detection sensitivity. At the same time, the cost of the pressure-sensitive sensor is lower. In addition, due to the working principle of the capacitive sensor, it is seriously affected by the environment or the user. For example, when a user uses an electric toothbrush, their hands are usually wet, which has a greater impact on the capacitive sensor and may also cause the capacitive sensor to malfunction. At the same time, since electric toothbrushes are mostly used in humid environments such as toilets, humid environments will also have a greater impact on the capacitive sensor. In summary, when using the technical solution provided by this embodiment, compared with using a capacitive sensor to prevent accidental touches, its effect is more stable and will not be affected in a humid environment.

[0051] Furthermore, the pressure sensor includes a pressure-sensitive element, a pressure detection circuit, an output circuit, a feedback circuit, a power supply circuit and a ground circuit; wherein the pressure-sensitive element is used to obtain pressure; one end of the output circuit, the feedback circuit, the power supply circuit and the ground circuit are respectively connected to the pressure-sensitive element; the output circuit is connected in parallel to the pressure detection circuit, for detecting the pressure value of the pressure obtained by the pressure-sensitive element through the pressure detection circuit; and the other end of the output circuit is connected to the input end of the detection chip for outputting the pressure value; the feedback circuit is connected in parallel to the pressure detection circuit, and the other end of the feedback circuit is connected to the feedback end of the detection chip for obtaining a comparison result; the other end of the power supply circuit is connected to a power supply for powering the pressure-sensitive element; the other end of the ground circuit is grounded for protecting the pressure sensor.

[0052] In this embodiment, the first button 201 and the second button 202 are described in detail. It should be noted that since the first button 201 and the second button 202 are both identical pressure-sensing buttons, only the pressure sensor in one of the pressure-sensing buttons is described in this embodiment. The pressure sensor includes a pressure-sensitive element, a pressure detection circuit, an output circuit, a feedback circuit, a power supply circuit, and a ground circuit.

[0053] The pressure-sensitive element is a unit for obtaining pressure. When the user presses the first button 201 or the second button 202 , the pressure-sensitive element detects the pressure generated by the pressing.

[0054] The pressure detection circuit detects the pressure obtained by the pressure-sensitive element by the user to obtain an accurate pressure value of the pressure, which is the first pressure value and the second pressure value mentioned above.

[0055] The output circuit is used to output the aforementioned first pressure value and second pressure value to the detection chip so that the detection chip can perform operations on the first pressure value and the second pressure value. It should be noted that the operations described here include but are not limited to comparing the first pressure value and the second pressure value, and / or comparing the first pressure value and / or the second pressure value with the pressure threshold value respectively.

[0056] The feedback circuit is used to feed back the comparison result of the detection chip to the pressure sensor. The pressure sensor controls the pressure detection circuit to obtain the first pressure value and the second pressure value according to the comparison result, so as to improve the detection accuracy and sensitivity of the first pressure value and the second pressure value to meet the requirements of the detection chip.

[0057] The power supply circuit is used to supply power to the pressure sensitive element.

[0058] Ground circuit to protect the pressure sensor.

[0059] Here we will describe the pressure sensor in detail again, such as Figure 3 and Figure 4As shown, one end of the output circuit, the power supply circuit and the ground circuit are respectively connected to the pressure sensitive element, and the output circuit is connected in parallel in the pressure detection circuit, for detecting the pressure value of the pressure obtained by the pressure sensitive element through the pressure detection circuit, and the other end of the output circuit is linked to the input terminal of the detection chip to output the pressure value to the detection chip. It should be noted that when the pressure sensor is the pressure sensor in the first button 201, the pressure value described here is the first pressure value, and when the pressure sensor is the pressure sensor in the second button 202, the pressure value described here is the second pressure value. The feedback circuit is connected in parallel to the pressure detection circuit, and the other end of the feedback circuit is connected to the feedback terminal of the detection chip to obtain the comparison result. The other end of the power supply circuit is connected to the power supply, and the user supplies power to the pressure sensitive element. The other end of the ground circuit is grounded to protect the pressure sensor.

[0060] Furthermore, the pressure detection circuit includes a first resistor, a first capacitor, a second capacitor, and a second resistor connected in series in sequence; and the other end of the first resistor is grounded, and the first capacitor and the second capacitor are grounded respectively; a third capacitor is connected in parallel on both sides of the first capacitor and the second capacitor, and the two parallel points of the third capacitor are respectively the first parallel point and the second parallel point.

[0061] The resistance of the first resistor is 297KΩ to 303KΩ;

[0062] The resistance of the second resistor is 297KΩ to 303KΩ.

[0063] In this embodiment, the aforementioned pressure detection circuit is described in detail. The pressure detection circuit includes a first circuit, a first capacitor, a second capacitor, and a second resistor connected in series to form a series path. The other end of the first resistor is grounded to protect the pressure detection circuit. A third capacitor is connected in parallel on both sides of the first and second capacitors. For ease of description and understanding, the two parallel points of the third capacitor are the first parallel point and the second parallel point, respectively.

[0064] It should be noted that the resistance range of the first resistor is 297KΩ to 303KΩ, and the resistance range of the second resistor is the same as the resistance range of the first resistor, which is 297KΩ to 303KΩ. In some embodiments, the resistance of the first resistor and the second resistor is 300KΩ.

[0065] Furthermore, the output circuit is connected in parallel to the connection line between the second resistor and the second parallel point; and the feedback circuit is connected in parallel to the connection line between the first resistor and the first parallel point.

[0066] In this embodiment, the relationship between the output circuit and the feedback circuit and the pressure detection circuit is specifically described. The output circuit is connected in parallel to the connection line between the second resistor and the second parallel point of the pressure detection circuit. In some embodiments, the output circuit can also be connected in parallel to the contact point between the second resistor and the second parallel point. The feedback circuit is connected in parallel to the connection line between the first resistor and the first parallel point of the pressure detection circuit. In some embodiments, the feedback circuit can also be connected in parallel to the contact point between the first resistor and the second parallel point. That is, in this embodiment, the parallel connection points of the output circuit and the feedback circuit with the pressure detection circuit are described.

[0067] Furthermore, the first button 201 and the second button 202 are adjacently arranged on the same side of the housing 2, and the first button 201 corresponds to the center position of the pressing fingertip, and the second button 202 corresponds to the edge position of the pressing fingertip.

[0068] In this embodiment, the positions of the first button 201 and the second button 202 on the shell are described one by one. In this embodiment, the first button 201 and the second button 202 are adjacently arranged on the same side of the shell 2. This embodiment is described with the side where the thumb is located when the user uses the electric toothbrush as the front side, that is, the first button 201 and the second button 202 are both arranged on the front side of the electric toothbrush, and the first button 201 and the second button 202 are adjacently arranged, including but not limited to being adjacent in the upper, lower, left and right positions. It is sufficient that the first button 201 corresponds to the center position of the thumb and the second button 202 corresponds to the edge position of the center position of the thumb. For example, when the first button 201 and the second button 202 are positioned adjacent to each other at the top and bottom, due to the special shape of the thumb tip and people's common pressing habits, it is obvious that when a user presses with their thumb, the pressing force at the center of the thumb will be greater than the pressing force at the edge of the thumb center. Therefore, when the user presses the first button 201 with the center of the thumb to generate a first pressure value, the second button 202 will also generate a second pressure value due to the pressing force at the edge of the thumb center. Obviously, the first pressure value will be greater than the second pressure value, so it is determined that the user is operating the electric toothbrush, and the electric toothbrush is operated according to the user's operation. In this embodiment, by arranging the first button 201 and the second button 202 adjacent to each other on the front side of the housing 2, due to the special shape of the thumb and people's pressing habits, the first pressure value will be greater than the second pressure value, thereby determining that the user is operating the electric toothbrush, thereby reducing accidental touches. It should also be noted that in some embodiments, by setting a first pressure threshold and a second pressure threshold for the first pressure value and the second pressure value, respectively, it is determined whether the user is operating the electric toothbrush by determining whether the first pressure value is greater than the first pressure threshold and the second pressure value is less than the second pressure threshold. It should also be noted that the methods described in the above two embodiments can be used simultaneously for combined determination, that is, it is required that the first pressure value is greater than the second pressure value, and that the first pressure value is greater than the first pressure threshold and the second pressure value is less than the second pressure threshold.

[0069] Furthermore, the first button 201 and the second button 202 are arranged on opposite sides of the housing 2, and the first button 201 is arranged at the position where the fingertip points when holding the electric toothbrush, and the second button 202 is arranged at the position where the holding finger points when holding the electric toothbrush.

[0070] In this embodiment, another position of the first button 201 and the second button 202 on the shell is described. In this embodiment, the first button 201 and the second button 202 are arranged on opposite sides of the shell 2, that is, the first button 201 is arranged on the front side of the shell 2, and the second button 202 is arranged on the back side of the shell 2. When holding the electric toothbrush, the electric toothbrush is held by the other four fingers and the palm except the thumb, and the thumb presses a button to control the electric toothbrush. That is, in this embodiment, the thumb presses the first button 201 to generate a first pressure value, and because the other four fingers need to exert a certain force to effectively hold the electric toothbrush when the user holds the electric toothbrush to prevent the electric toothbrush from falling, the second button 202 is set to correspond to any finger and / or all of the other four fingers, and a second pressure value is generated when the user holds the electric toothbrush. Due to people's holding habits and pressing habits, it is obvious that the first pressure value generated when the user presses the first button 201 with the thumb will be greater than the second pressure value, so as to identify whether the user is operating the electric toothbrush. Since the above embodiment has described how to determine whether the user is operating the electric toothbrush and the beneficial effects by the first pressure value and the second pressure value, it will not be described here again, and you can refer to the above. It should be noted that in this embodiment, the first button 201 is set to correspond to the thumb, and the second button 202 is set to correspond to the index finger. The description here is only for the convenience of understanding the difference from the above embodiment, and does not serve as a limitation. In fact, the second button 202 can be set to correspond to the little finger, ring finger, middle finger, and index finger respectively.

[0071] Furthermore, the first button 201 and the second button 202 are arranged on adjacent sides of the housing 2, and the first button 201 is arranged at the position where the fingertip points when holding the electric toothbrush, and the second button 202 is arranged at the position where the holding finger points when holding the electric toothbrush.

[0072] In this embodiment, another position of the first button 201 and the second button 202 on the housing is described. In this embodiment, the first button 201 is arranged on the front side of the housing 2, and the second button 202 is arranged on the left or right side of the housing. When holding the electric toothbrush, the electric toothbrush is held by the other four fingers and the palm of the hand except the thumb, and the thumb presses a button to control the electric toothbrush. That is, in this embodiment, the thumb presses the first button 201 to generate a first pressure value. When the user holds the electric toothbrush, the other four fingers need to exert a certain force to effectively hold the electric toothbrush to prevent the electric toothbrush from falling. Therefore, the second button 202 is arranged to correspond to the fingertips of any and / or all of the other four fingers. When the user holds the electric toothbrush, a second pressure value is generated. Due to people's holding habits and pressing habits, it is obvious that the first pressure value generated when the user presses the first button 201 with the thumb will be greater than the second pressure value, thereby identifying whether the user is operating the electric toothbrush. Since the previous embodiment has already described how to determine whether the user is operating the electric toothbrush and the beneficial effects thereof using the first and second pressure values, this description will not be repeated here. It should be noted that the second button 202 corresponds to the fingertip of the index finger. Furthermore, this description is merely for the purpose of facilitating understanding and distinguishing the difference from the previous embodiment and is not intended to be limiting. In practice, the second button 202 can correspond to the fingertips of the little finger, ring finger, middle finger, and index finger, respectively.

[0073] Furthermore, the electric toothbrush provided in this embodiment also includes a brush head and a transmission device 3; wherein, the multiple actuators include at least a power element, and the transmission device 3 is arranged in the handle 1 and has one end transmission connected to the power element; the brush head is detachably connected to one end of the handle 1 and is transmission connected to the other end of the transmission device 3; when the control chip controls the operation of the power element according to the comparison result, the power element drives the brush head to vibrate and / or sweep through the transmission device 3.

[0074] In this embodiment, the electric toothbrush also includes a brush head detachably connected to the brush handle and a transmission device 3 for user power transmission. The multiple actuators include at least one power element. The transmission device 3 is arranged in the handle 1, and one end is transmission-connected to the power element, and the other end is transmission-connected to the brush head. When the control chip controls the power element to operate according to the comparison result, the power element drives the brush head to vibrate and / or sweep through the transmission device 3 to complete the cleaning of the teeth.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
