Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0050] In order to solve the technical problems mentioned in the above background technology, an embodiment of the present utility model provides a toothbrush handle 100.

[0051] Reference Figures 1 to 4The toothbrush handle 100 includes: a housing 110, a motor 120 and a detection assembly 130. The housing 110 is provided with an opening K; the motor 120 includes a housing 121, a stator 122, a rotor 123 and an output shaft 124. The housing 121 can be movably installed in the housing 110, the stator 122 and the rotor 123 are both arranged in the housing 121, the stator 122 is fixed relative to the housing 121, the output shaft 124 is connected to the rotor 123 and can rotate with the rotor 123 relative to the stator 122, and the rotation of the rotor 123 relative to the stator 122 The movable angle is not less than 60°, one end of the output shaft 124 passes through the casing 121 and is connected to the brush head 200 through the opening K. The brush head 200 is subjected to force to drive the casing 121 to move relative to the outer shell 110; the detection component 130 is arranged in the outer shell 110, and the detection component 130 includes a first detection member 131 and a second detection member 132. The first detection member 131 is connected to the casing 121 and moves with the casing 121 relative to the outer shell 110. The second detection member 132 cooperates with the first detection member 131 to detect the pressure exerted on the brush head 200.

[0052] The toothbrush handle 100 involved in this embodiment is the main structure of the electric toothbrush, which is combined with the brush head 200 to form the electric toothbrush as a whole. In common usage scenarios, when the user needs to brush teeth, the brush head 200 can be installed on the toothbrush handle 100 to brush teeth; when there is no need to brush teeth, the user can remove the brush head 200 from the toothbrush handle 100 and place the two separately. Figure 2 and Figure 3 As shown, the shell 110 of the toothbrush handle 100 of the embodiment of the present application is generally in the shape of a long cylinder, and an accommodation space is formed inside the shell 110 for accommodating multiple driving components, such as a motor 120, a detection component 130, etc. In addition, the interior of the shell 110 can also accommodate a control circuit board, a battery, etc., which are not described in detail here.

[0053] like Figure 3 and Figure 4 As shown, the motor 120 includes a housing 121, a stator 122, a rotor 123 and an output shaft 124. The stator 122 is fixedly arranged in the housing 121, and the output shaft 124 is connected to the rotor 123. The rotor 123 can drive the output shaft 124 to rotate relative to the stator 122, and one end of the output shaft 124 passes through the housing 121. In the embodiment of the present application, the motor 120 can be a servo motor 120, and the rotation angle of the rotor 123 relative to the stator 122 can be 60°, 90°, 120°, 150°, 180°, etc. The rotation angle of the rotor 123 relative to the stator 122 can be the angle at which the rotor 123 can rotate relative to the stator 122 when the motor 120 is actively controlled to run, or it can be the angle at which the output shaft 124 of the motor 120 can rotate relative to the stator 122 when an external force acts on it.

[0054] Continue to see Figure 3 , an opening K is provided at one end of the housing 110, and the output shaft 124 passes through the opening K, and both sides of the end of the output shaft 124 are configured as thinned planes to connect the brush head 200. After the brush head 200 is connected to the output shaft 124, it swings back and forth within a certain angle range with the output shaft 124 under the drive of the motor 120, and in the process of contacting the teeth, the toothpaste is decomposed into fine foam to achieve in-depth cleaning of the positions such as the gaps between teeth. It should be understood that the swing angle range of the brush head 200 can be set according to actual conditions and is not limited here.

[0055] In the embodiment of the present application, the housing 121 can move relative to the housing 110. There are many forms of movement of the housing 121, which may include rotation, translation, etc., and can be set according to actual conditions. Preferably, the housing 121 is rotatably installed in the housing 110. Since the housing 121 can move relative to the housing 110, in actual use, when the brush head 200 is subjected to force (for example, during brushing, the bristles 210 of the brush head 200 contact the teeth and are subjected to force), the force applied to the brush head 200 is transmitted to the output shaft 124 of the motor 120, so that the housing 121 rotates relative to the housing 110.

[0056] Reference Figure 4, the detection assembly 130 includes a first detection member 131 and a second detection member 132, and the pressure on the brush head 200 is detected by the cooperation of the first detection member 131 and the second detection member 132. The first detection member 131 is connected to the housing 121 and moves with the housing 121 relative to the housing 110, and the second detection member 132 is fixedly arranged in the housing 110 relative to the housing 110. Specifically, the second detection member 132 is located on the moving path of the first detection member 131, or the second detection member 132 is located in the moving direction of the first detection member 131, or the second detection member 132 is arranged relative to the first detection member 131. In this way, during the movement of the first detection member 131 with the housing 121, the first detection member 131 is relatively close to the second detection member 132 or relatively far away from the second detection member 132, and the second detection member 132 can cooperate with the first detection member 131 to detect the distance between the two, and then detect the active state of the housing 121, thereby detecting the pressure on the brush head 200. For example, when the second detection member 132 cooperates with the first detection member 131 to detect that the distance between them is gradually reduced, it is correspondingly represented by the housing 121 moving toward the first direction (such as rotating clockwise), and the pressure on the brush head 200 is gradually increased; and when the second detection member 132 cooperates with the first detection member 131 to detect that the distance between them is gradually increased, it is correspondingly represented by the housing 121 moving toward the second direction (such as rotating counterclockwise), and the pressure on the brush head 200 is gradually reduced. In the embodiment of the present application, the device type of the first detection member 131 and the second detection member 132 can be set according to actual conditions, which will be further described in detail in the subsequent embodiments and will not be described in detail here.

[0057] In the embodiment of the present application, when the user holds the toothbrush handle 100 and the bristles 210 of the brush head 200 touch the teeth, the brush head 200 is subjected to the force of the teeth and transmitted to the motor 120, so that the motor 120 moves as a whole, and then the housing 121 of the motor 120 moves relative to the housing 110, and the second detection member 132 cooperates with the first detection member 131 to detect the pressure on the brush head 200. Since the first detection member 131 is configured to be connected to the housing 121 of the motor 120, the pressure on the brush head 200 is detected by cooperating with the second detection member 132 and the first detection member 131, so that the second detection member 132 and the first detection member 131 will not rotate with the rotor, thereby avoiding the entanglement of the wire connected to the detection component 130, thereby eliminating the risk of the wire connected to the detection component 130 being broken, and ensuring the reliability and service life of the electric toothbrush.

[0058] In some embodiments, the motor 120 is configured so that the output shaft 124 has an initial position that is reset when started. When the output shaft 124 is reset to the initial position when the motor 120 is started, the bristles 210 of the brush head 200 face in a first direction; when the output shaft 124 is subjected to a force opposite to the first direction, the housing 121 moves, and the first detection member 131 and the second detection member 132 cooperate to detect the pressure exerted on the brush head 200.

[0059] In this embodiment, the motor 120 has a function of resetting the output shaft 124. When the motor 120 is powered on, the output shaft 124 is controlled to be reset to the initial position. When the motor 120 is started and the output shaft 124 is reset to the initial position, the bristles 210 of the brush head 200 face the first direction. In actual application scenarios, when the user uses the electric toothbrush, he controls the electric toothbrush to turn on by operating the switch button. The motor 120 is powered on to control the output shaft 124 to reset to the initial position. The brush head 200 rotates with the output shaft 124 so that the brush head 200 faces the first direction.

[0060] Furthermore, when brushing teeth, the bristles 210 face and contact the teeth, so that the output shaft 124 is subjected to a force opposite to the first direction. Under the action of this force, the housing 121 moves, and the first detection member 131 and the second detection member 132 cooperate to detect the pressure on the brush head 200.

[0061] It should be understood that according to the detection design of the toothbrush handle, when the output shaft 124 is subjected to a force opposite to the first direction, the housing 121 can be moved, and the range of movement of the housing 121 is consistent with the range of movement under the preset standard force condition, and the first detection member 131 and the second detection member 132 can cooperate to accurately detect the pressure on the brush head 200. Therefore, by controlling the output shaft 124 to reset to the initial position when the motor 120 is powered on, the bristles 210 face the first direction to ensure that when the bristles 210 are in contact with the teeth for brushing, the output shaft 124 is subjected to a force opposite to the first direction, thereby achieving accurate detection of the pressure on the brush head 200.

[0062] In some embodiments, the motor 120 is configured so that the output shaft 124 rotates within a preset angle range, the output shaft 124 is subjected to force, the housing 121 moves, and the first detection member 131 cooperates with the second detection member 132 to detect the pressure exerted on the brush head 200. In the embodiment of the present application, the preset angle range involved can be set according to actual conditions and is not limited to this. For example, the preset angle range can be +30° to -30°, and the motor 120 controls its output shaft 124 to rotate within +30° to -30°. Optionally, when the output shaft 124 rotates to 0°, the bristles 210 of the brush head 200 face in the first direction.

[0063] According to the detection design of the toothbrush handle, when the rotation angle of the output shaft 124 is within a non-preset angle range, the orientation of the brush head 200 is inconsistent with the orientation of the standard movement of the housing 121 when the brush head 200 is subjected to force. In this case, even if the output shaft 124 is subjected to force, the housing 121 may not move, or the amplitude of the movement of the housing 121 may not match the amplitude of the movement under the preset standard force condition, resulting in the inability to detect the pressure on the brush head 200 or the detected pressure on the brush head 200 is inaccurate.

[0064] Therefore, by configuring the motor 120 so that the output shaft 124 rotates within a preset angle range, when the output shaft 124 is subjected to force, the housing 121 can be moved, and the amplitude of the movement of the housing 121 is basically consistent with the amplitude of the movement under the preset standard force condition, and the first detection member 131 and the second detection member 132 can cooperate to detect the pressure on the brush head 200, thereby realizing accurate detection of the pressure on the brush head 200.

[0065] In some embodiments, when the output shaft 124 rotates to a non-preset angle range, the motor 120 is configured to be powered on to reset the output shaft 124 to a preset angle range. In the embodiment of the present application, the motor 120 is configured to be powered on to reset the output shaft 124 to a preset angle range when the output shaft 124 rotates to a non-preset angle range. In actual application, the output shaft 124 may be rotated to a non-preset angle range due to factors such as collision and impact, thereby causing the pressure on the brush head 200 to be unable to be detected or inaccurately detected. Therefore, when the output shaft 124 rotates to a non-preset angle range, the motor 120 is configured to be powered on to reset the output shaft 124 to a preset angle range, so as to achieve automatic correction and deviation correction of the rotation angle of the output shaft 124, so as to accurately detect the pressure on the brush head 200.

[0066] In some embodiments, the output shaft 124 of the motor 120 has an initial position and the initial position is adjustable, and the adjustable angle of the initial position is within a preset angle range. In the embodiment of the present application, the motor 120 is configured so that the output shaft 124 has an initial position and the initial position is adjustable, and the adjustable angle of the initial position is within a preset angle range. When the motor 120 is powered on and started, its output shaft 124 can be controlled to rotate to the initial position. The motor 120 has an initial position adjustment function for the output shaft 124, and the adjustable angle of the initial position of the output shaft 124 is within a preset angle range to ensure that when the output shaft 124 is in the initial position, the rotation angle of the output shaft 124 is correspondingly within the preset angle range, so that when the output shaft 124 is subjected to force, the housing 121 can be moved, and the amplitude of the movement of the housing 121 is substantially consistent with the amplitude of the movement under the preset standard force condition, and the first detection member 131 and the second detection member 132 can be correspondingly made to cooperate in detecting the pressure on the brush head 200, so as to achieve accurate detection of the pressure on the brush head 200.

[0067] The motor 120 is configured to mean that the motor 120 is provided with an electrical control device, through which the output shaft 124 of the motor 120 can be set to rotate only within a preset angle range, and / or, the motor 120 can be set so that when the output shaft 124 rotates to a non-preset angle range, the output shaft 124 is reset to the preset angle range upon power-on, and / or, the output shaft 124 of the motor 120 can be set to have an adjustable initial position, and the adjustable angle of the initial position is within the preset angle range.

[0068] In the above embodiment, the rotation angle of the output shaft 124 can be detected and acquired by configuring an angle sensor. The angle sensor can be a Hall sensor or the like, and can be set according to actual conditions.

[0069] Reference Figure 5 and Figure 6 In the embodiment of the present application, the toothbrush handle 100 may further include: a reset member 140, which is disposed in the housing 110 and acts on the housing 121. The reset member 140 is used to drive the housing 121 to reset after the pressure on the brush head 200 is removed. Specifically, after the pressure on the brush head 200 is removed, the housing 121 is automatically reset by the reset member 140, so as to perform the next pressure detection of the brush head 200.

[0070] The reset member 140 in the embodiment of the present application may include a reset spring 1411; a third mounting bracket J3 is arranged in the housing 110, and the third mounting bracket J3 is located on one side of the motor 120, one end of the reset spring 1411 is connected to the third mounting bracket J3, and the other end of the reset spring 1411 acts on the housing 121.

[0071] In combination with the above-mentioned embodiment, the third mounting frame J3 can be combined with the first mounting frame J1. Figure 6 As shown, the third mounting frame J3 is formed with the aforementioned shaft hole O, and the first mounting frame J1 is rotatably mounted on the third mounting frame J3. One end of the return spring 1411 is connected to the third mounting frame J3, and the other end acts on the housing 121 through being connected to the first mounting frame J1.

[0072] In the embodiment of the present application, one or more return springs 1411 may be provided. Figure 7 As shown, two return springs 1411 are provided, and the two return springs 1411 are respectively located on opposite sides of the detection assembly 130 .

[0073] When the brush head 200 is subjected to pressure (for example, the brush head 200 is subjected to force due to contact with the teeth), causing the housing 121 to move, the reset spring 1411 is squeezed to deform to accumulate elastic potential energy; when the pressure on the brush head 200 is removed (for example, the bristles 210 of the brush head 200 are separated from the teeth), the reset spring 1411 is restored to its original shape to release the elastic potential energy, and the reset spring 1411 drives the housing 121 to move accordingly, and the housing 121 is reset under the action of the elastic force of the reset spring 1411.

[0074] Reference Fig. 9 In the embodiment of the present application, the housing 121 has at least two movable directions;

[0075] The detection components 130 include at least two groups. Each group of detection components 130 detects the activity state of the housing 121 in one of the activity directions through the cooperation between the second detection member 132 and the first detection member 131 to detect the pressure exerted on the brush head 200.

[0076] In this embodiment, multiple groups of detection components 130 are correspondingly arranged according to the multiple movement directions of the housing 121, and each group of detection components 130 is responsible for detecting the movement state of the housing 121 in one of the movement directions, and then detecting the pressure on the brush head 200. For example, in combination with the above-mentioned embodiment, the movement form of the housing 121 is rotation, and the housing 121 has a counterclockwise rotation direction and a clockwise rotation direction. The detection components 130 include two groups, one of which is arranged on the counterclockwise side of the housing 121, so as to detect the movement state of the housing 121 in the counterclockwise rotation direction through its second detection member 132 and the first detection member 131, so as to detect the pressure on the brush head 200; and the other group is arranged on the clockwise side of the housing 121, so as to detect the movement state of the housing 121 in the clockwise rotation direction through its second detection member 132 and the first detection member 131, so as to detect the pressure on the brush head 200.

[0077] When the brush head 200 is subjected to pressure causing the housing 121 to rotate, the multiple sets of detection components 130 correspondingly detect in real time the activity status of the housing 121 in their respective corresponding activity directions. Furthermore, the detection data obtained by the multiple sets of detection components 130 can be compared and cross-checked to improve the accuracy of the detection data and achieve accurate detection of the pressure on the brush head 200.

[0078] Reference Fig.10 In the aforementioned embodiment, since the housing 121 has multiple movable directions, the reset member 140 is also provided in plurality, and each reset member 140 is used to apply a force to the housing 121 to reset it along one of the movable directions.

[0079] In this embodiment, according to the multiple movement directions of the housing 121, a plurality of reset members 140 are correspondingly arranged, and each reset member 140 is corresponding to the reset of the auxiliary housing 121 in one of the movement directions. For example, in combination with the above-mentioned embodiment, the movement form of the housing 121 is rotation, and the housing 121 has a counterclockwise rotation direction and a clockwise rotation direction. The reset members 140 include two, one of which is arranged on the counterclockwise side of the housing 121 to apply a force to the housing 121 to reset it in the clockwise direction; and the other reset member 140 is arranged on the clockwise side of the housing 121 to apply a force to the housing 121 to reset it in the counterclockwise direction. Through the multiple reset members 140, the accurate reset of the housing 121 in its multiple directions can be achieved.

[0080] In the embodiment of the present application, there are many ways to install the first detection member 131. Figure 4 and Figure 5 In a preferred embodiment, a movable first mounting bracket J1 is disposed in the housing 110, the motor 120 is fixedly connected to the first mounting bracket J1, and the first detection member 131 is connected to the housing 121 through the first mounting bracket J1.

[0081] In this embodiment, the first mounting frame J1 is movably disposed in the housing. The frame of the first mounting frame J1 may be a semi-enclosed frame having a receiving groove for mounting the motor 120. Half of the housing 121 of the motor 120 is received in the receiving groove. In this embodiment of the application, the first mounting frame J1 may rotate relative to the housing. Figure 5 and Figure 6As shown, the first mounting frame J1 is connected to the rotating shaft Z at the symmetrical positions on the opposite sides, and the first mounting frame J1 is inserted into the shaft hole O through the rotating shaft Z, so as to be rotatable relative to the housing 110. Furthermore, the axis of the rotating shaft Z may coincide with the rotation axis of the housing 121, and the shaft hole O may be formed on other components in the housing 110, or may be formed on the inner wall of the housing 110. In the embodiment of the present application, the first detection member 131 is disposed on the first mounting frame J1, and the first detection member 131 is connected to the housing 121 through the first mounting frame J1, that is, the first detection member 131 is indirectly connected to the housing 121. When the brush head 200 is subjected to force to make the housing 121 move, the housing 121 drives the first mounting frame J1 to move, and then the first detection member 131 disposed on the first mounting frame J1 moves with the housing 121.

[0082] In another preferred embodiment of the present application, the first detection member 131 can be disposed on the outer wall of the housing 121, that is, the first detection member 131 is directly connected to the housing 121. Specifically, the first detection member 131 can be disposed on the outer wall of the housing 121, that is, the first detection member 131 can be disposed on the outer peripheral wall of the housing 121, or on the outer end wall of the housing 121. When the brush head 200 is subjected to force to move the housing 121, the first detection member 131 disposed on the outer wall of the housing 121 moves with the housing 121.

[0083] There are also multiple options for the position of the first detection member 131. Figure 5 and Figure 6 In a preferred embodiment, the first detection member 131 is located at the end of the housing 121 away from the output shaft 124. The first detection member 131 may be arranged on the first mounting frame J1 connected to the motor 120, or may be arranged on the outer wall of the housing 121. Regardless of which of the above arrangements is adopted, the first detection member 131 is located at the end of the housing 121 away from the output shaft 124. In the embodiment of the present application, since the first detection member 131 is arranged at the end of the housing 121 away from the output shaft 124, when the brush head 200 is subjected to force to cause the housing 121 to rotate, the rotation amplitude of the end of the housing 121 away from the output shaft 124 is the largest, and the second detection member 132 cooperates with the first detection member 131 to detect the change in the distance between the two more accurately, and can achieve accurate detection of the activity state of the housing 121, thereby improving the detection accuracy of the pressure on the brush head 200.

[0084] Reference Figure 5In the embodiment of the present application, the first detection member 131 can also be installed in the end surface of the housing 121 away from the output shaft 124, that is, the setting position of the first detection member 131 does not exceed the edge of the end surface of the housing 121. The embodiment of the present application reasonably utilizes the radial space of the housing 110 occupied by the housing 121 to set the first detection member 131, thereby improving the compactness of the structure of the toothbrush handle. Compared with the arrangement scheme of setting the first detection member 131 on the peripheral side of the housing 121, the radial size of the housing 110 can be reduced.

[0085] In this embodiment, the second detection member 132 can be arranged in a variety of ways, as long as the conditions for cooperating with the first detection member 131 for detection are met. For example, in the aforementioned embodiment, the first detection member 131 is arranged in the end surface of the housing 121 away from the output shaft 124, and the second detection member 132 can also be arranged in the end surface of the housing 121 away from the output shaft 124, and arranged opposite to the first detection member 131. Since the second detection member 132 is arranged at a position that does not exceed the edge of the end surface, the compactness of the structure can be further improved.

[0086] In a preferred embodiment, the second detection member 132 may also be disposed on the inner wall of the outer shell 110. The second detection member 132 is disposed on the inner wall of the outer shell 110, that is, the second detection member 132 is directly connected to the outer shell 110. The second detection member 132 may be disposed on the inner wall of the outer shell 110 in a detachable manner or in a fixed manner, and may be disposed according to actual conditions such as the type of device adopted by the second detection member 132. In another preferred embodiment, a second mounting frame is disposed in the outer shell 110, and the second mounting frame is relatively fixed to the outer shell 110 in the outer shell 110, and the second mounting frame may be used to assist in the installation of other components in the outer shell 110. Furthermore, the second detection member 132 is disposed on the second mounting frame, wherein the second detection member 132 may be disposed on the second mounting frame in a detachable manner or in a fixed manner, and may be disposed according to actual conditions such as the type of device adopted by the second detection member 132. Refer to Figure 4 and Figure 5 In another preferred embodiment, a circuit board D is disposed in the housing 110, and the circuit board D is located on one side of the motor 120. The second detection component 132 is disposed on the circuit board D and is electrically connected to the circuit board D. In the embodiment of the present application, the circuit board D is detachably disposed in the housing 110 and is relatively fixed to the housing 110. The circuit board D may be a main control circuit board, or an auxiliary control circuit board, or a circuit board with other functions. The second detection component 132 is disposed on the circuit board D and is electrically connected to the circuit board D. In this way, there is no need for additional wiring between the second detection component 132 and the circuit board D, thereby avoiding structural interference between the line body and other structures in the housing 110, and signal transmission is stable.

[0087] In the embodiment of the present application, there are multiple options for the type of the detection component 130. Figures 4 to 7 In some embodiments, the detection component 130 may be a contact detection component, one of the first detection member 131 and the second detection member 132 is a contact switch 1321, and the other is a contact member 1311, and the contact member 1311 is used to trigger the contact switch 1321, so that the contact switch 1321 sends an electrical signal. In this embodiment, the detection component 130 adopts a contact detection component, which has high detection accuracy and reliable operation. The first detection member 131 may be a contact switch 1321, and the second detection member 132 may be a contact member 1311, or the second detection member 132 may be a contact switch 1321, and the first detection member 131 may be a contact member 1311. When the brush head 200 is subjected to force to move the housing 121, the first detection member 131 of the detection assembly 130 contacts the second detection member 132, specifically the contact member 1311 contacts the switch 1321 to trigger it, so that the contact switch 1321 sends an electrical signal, thereby detecting the activity state of the housing 121 to detect the pressure on the brush head 200. Optionally, the contact switch 1321 is a micro switch, the triggering portion of the micro switch faces the contact member 1311, and the contact member 1311 can trigger the micro switch by contacting the triggering portion.

[0088] Reference Figure 4 and Figure 5 In some embodiments, the first detection member 131 is a contact member 1311, and the contact member 1311 is a first protrusion protruding from the first mounting frame J1. The first protrusion can be integrally formed with the first mounting frame J1. When the brush head 200 is subjected to force to move the housing 121, the housing 121 correspondingly drives the first mounting frame J1 to move, and then the contact switch 1321 can be triggered through the first protrusion on the first mounting frame J1.

[0089] Alternatively, in some embodiments, the first detection member 131 is disposed on the outer wall of the housing 121, and the first detection member 131 is a contact member 1311, and the contact member 1311 is a second protrusion protruding from the outer wall of the housing 121. The second protrusion may be integrally formed with the housing 121. When the brush head 200 is subjected to force to move the housing 121, the contact switch 1321 may be triggered by the second protrusion on the housing 121.

[0090] In the embodiment of the present application, the second detection member 132 can be an electrical component, and the first detection member 131 is a non-electrical component. It should be noted that the electrical component in the embodiment of the present application is a component that needs to be powered on, and the non-electrical component is a component that does not need to be powered on. The second detection member 132 is an electrical component, and the first detection member 131 is an electrical component. There are many combinations of the two. For example, the second detection member 132 can be the contact switch 1321 mentioned in the aforementioned embodiment, and the first detection member 131 is the contact member 1311 mentioned in the aforementioned embodiment, such as the first protrusion and the second protrusion shown in the example. In addition, it can also be other, such as the second detection member 132 uses a camera, the first detection member 131 is a convex point for camera recognition, etc., according to actual conditions.

[0091] Since the first detection member 131 is not powered, the first detection member 131 will not generate heat during use, and thus will not affect the working performance of the motor 120. In addition, the first detection member 131 does not need to be connected to a wire, thereby completely avoiding the entanglement of the wire that may occur when connected to the first detection member 131.

[0092] In other embodiments of the present application, the detection component 130 may also be a non-contact detection component, and the non-contact detection component 130 includes at least one of a camera detection device, a laser detection device, a radar detection device, and an infrared detection device. In this embodiment, the detection component 130 adopts a non-contact detection component, which is less subject to interference and damage and has a long service life. Among them, the non-contact detection component has several types such as a camera detection device, a laser detection device, a radar detection device, and an infrared detection device. In actual application, the detection component 130 may be one or more of a camera detection device, a laser detection device, a radar detection device, and an infrared detection device, and is set according to actual conditions. Among them, one or more detection components 130 can be set. For example, when one detection component 130 is set, the detection component 130 may be one of a camera detection device, a laser detection device, a radar detection device, and an infrared detection device. For example, when multiple detection components 130 are set, it may be several of a camera detection device, a laser detection device, a radar detection device, and an infrared detection device. This is only exemplary and not restrictive.

[0093] Reference Figure 8In a preferred embodiment of the present application, the detection component 130 includes a camera detection device and an amplifying member F. The camera detection device includes a camera 1322 and an identification member 1312. One of the camera 1322 and the identification member 1312 is a first detection member 131, and the other is a second detection member 132. The amplifying member F is used to amplify the image of the identification member 1312 for collection by the camera 1322. In this embodiment, the camera 1322 of the camera detection device can be defined as the first detection member 131, and the identification member 1312 can be defined as the second detection member 132. Alternatively, the identification member 1312 of the camera detection device can be defined as the first detection member 131, and the camera 1322 can be defined as the second detection member 132. As a preferred option, the first detection member 131 uses the identification member 1312, and the second detection member 132 uses the camera 1322. When the brush head 200 is subjected to force to move the housing 121, the camera 1322 collects the image of the identification member 1312, detects the change in the distance between the identification member 1312 and the housing 121, and then detects the activity state of the housing 121, thereby detecting the pressure on the brush head 200. Optionally, the identification member 1312 can be a convex point that can be recognized by the camera 1322, including but not limited to this. Further, the detection component 130 also includes an amplifier F, which can be set at the front end of the camera 1322. By amplifying the image of the identification member F for collection by the camera 1322, the recognition accuracy of the camera 1322 can be improved, thereby improving the detection accuracy. Optionally, the amplifier F can be a lens that can magnify the image of an object.
