[0030] A pressure touch structure is a structure that can detect and respond to the pressure applied to it. It has a wide range of applications in the market, one of which is in the field of electric toothbrushes. By pressing the button with different forces or the number of times the button is pressed, the user can achieve different brushing modes and functions. However, if the pressure touch structure is not sensitive enough, it will be difficult to accurately sense the changes in pressure applied by the user. This may cause the user to encounter obstacles when trying to switch brushing modes or functions, and the system will not respond correctly, greatly reducing the user experience. In addition, most of the pressure touch structures on the market are mechanical sensing or capacitive sensing. The mechanical touch structure requires glue coating on the contact surface, which affects the appearance; while the capacitive touch structure is easy to touch by mistake in a humid environment, reducing the user experience.

[0031] Based on this, the present application provides a pressure touch structure, a button and an electric toothbrush to solve the above-mentioned technical problems. The technical solutions provided by the present application are described in detail one by one below.

[0032] First, refer to Figure 1 , Figure 2 and Figure 5The present application provides a pressure touch structure, including a control board 100, a sensitive component 200 and a force-bearing component, wherein a first opening groove 110 is provided on the control board 100, and second opening grooves 120 are respectively provided on both sides of the first opening groove 110, the second opening groove 120 is connected to the first opening groove 110, and the length of the second opening groove 120 is greater than the length of the first opening groove 110; the length of the sensitive component 200 is greater than the length of the first opening groove 110, the width of the sensitive component 200 matches the width of the first opening groove 110, and the contacts at both ends of the sensitive component 200 are electrically connected to the control board 100 and are located above the first opening groove 110; one side surface of the force-bearing component contacts with the surface of the sensitive component 200, and the other side surface of the force-bearing component is provided with a recessed portion 310; the force-bearing component is used to receive and transmit external force to the sensitive component 200, so that the sensitive component 200 converts the force signal into an electrical signal.

[0033] The sensitive component 200 is arranged on the control board 100 and is electrically connected to the control board 100 through the contact point. One side surface of the force-bearing component contacts the surface of the sensitive component 200, and a recessed portion 310 is arranged on the other side surface of the force-bearing component, and the position of the recessed portion 310 corresponds to the position of the sensitive component 200, so as to guide the user to the best touch position. When the external force-bearing component is subjected to pressure, the material is thinned by the recessed portion 310, which is beneficial to stress concentration and sensitivity improvement. On the other hand, the sensitive component 200 is arranged on the first side of the control board 100. At the position corresponding to an opening slot 110, the control board 100 is provided with a second opening slot 120 on both sides of the first opening slot 110, and the length L2 of the second opening slot 120 is greater than the length L1 of the first opening slot 110, so that the first opening slot 110 and the second opening slot 120 are connected to form an H-shaped window, the bridge support spacing is lengthened, and the cantilever is increased from the original L1 to L2. The sensitive component 200 is mounted above the H-shaped window, so that the sensitive component 200 has more deformation space, especially the middle is more prone to deformation, thereby improving the touch sensing sensitivity. Through the pressure touch structure provided by the present application, the control board 100 is provided with an H-shaped window formed by connecting the first opening slot 110 and the second opening slot 120, and a thinned recessed portion 310 is provided on the surface of the force-bearing component, which can make the received stress more concentrated, thereby improving the sensitivity of the pressure touch structure detection, thereby improving the user's experience of pressing touch. On the other hand, the force-bearing component can wrap the control board 100 and the sensitive part 200 as a whole. The entire force-bearing component is formed in one piece, and the triggering of the button is not based on capacitance, which effectively solves the problems of waterproofing and false triggering.

[0034] Reference Figure 1 and Figure 3It can be understood that the force-bearing component includes a contact member 300 and an elastic member 400. The contact member 300 is connected to the surface of the sensitive member 200 through the elastic member 400. The recessed portion 310 is arranged on the surface of the contact member 300 away from the sensitive member 200 and is located directly above the contact member 300. The contact member 300 is used to receive the force applied from the outside, and the elastic member 400 is used to transmit the force applied to the contact member 300 to the sensitive member 200, so that the sensitive member 200 converts the force signal into an electrical signal. The position of the recessed portion 310 corresponds to the position of the sensitive member 200, so as to guide the user to the best touch position, that is, to guide the user to press at the position of the recessed portion 310; when the external force-bearing component is subjected to pressure, the material thinning through the recessed portion 310 is conducive to stress concentration and sensitivity improvement. Due to the introduction of the elastic member 400, when the contact member 300 receives the external force, it can buffer and reduce shock through the elastic deformation of the elastic member 400, thereby reducing the impact of external shock or vibration on the sensitive member 200, thereby maintaining the accuracy of the force signal conversion. It should be noted that the contact member 300 is not limited to a flat panel here, but can also be a curved panel.

[0035] Reference Figure 1 and Figure 4 It can be understood that the elastic member 400 is a hollow structure at the bottom, the elastic member 400 is arranged on the control board 100 and is located on the peripheral side of the second opening groove 120, the sensitive member 200 is located in the hollow area of ​​the elastic member 400, and a protrusion 410 is provided in the hollow area of ​​the elastic member 400, and the protrusion 410 is in vertical contact with the surface of the sensitive member 200. The sensitive member 200 is located in the hollow area of ​​the elastic member 400, which can protect the elastic member 400. In addition, the sensitive member 200 is supported by the piers at both ends of the control board 100, so that the force sensitivity in the middle of the sensitive member 200 is the highest. The elastic member 400 is provided with a protrusion 410 in the central area of ​​the hollow area, and the protrusion 410 is in vertical contact with the central position of the sensitive member 200, so that the force is concentratedly transmitted to the middle position of the sensitive member 200, thereby improving the sensitivity of the sensitive member 200.

[0036] Reference Figure 3 It can be understood that the cross-section of the recessed portion 310 is arc-shaped, which is conducive to the contact member 300 to concentrate stress more evenly, and also helps to guide the user to perform pressing positions.

[0037] Reference Figure 4 It can be understood that the protrusion 410 in the elastic member 400 is cylindrical, and can also be rectangular or conical.

[0038] Reference Figure 6The third opening grooves 210 are symmetrically provided on both sides of the sensitive element 200. The third opening grooves 210 can be semicircular or square. Since the middle position is narrowed, it is easier to deform when subjected to force, which helps to concentrate stress and thus improve the sensing sensitivity.

[0039] In the second aspect, the present application further provides a button, comprising the pressure touch structure as described in any embodiment of the first aspect. The technical features and working principle of the button are based on the pressure touch structure mentioned above, and no more space will be wasted to re-introduce them.

[0040] In the third aspect, the present application also provides an electric toothbrush, including a button as described in the embodiment of the second aspect. The technical features and working principles of the electric toothbrush are based on the pressure touch structure mentioned above, and no more space will be wasted to reintroduce them here. It should be noted that when the pressure touch structure of the present application is specifically applied to an electric toothbrush, the contact piece can be set to a cylindrical shape, that is, the contact piece directly serves as the outer shell of the electric toothbrush, and the recessed portion is the touch position for function switching. The outer shell of the electric toothbrush can be integrally formed, which is more beautiful and simple as a whole.

[0041] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
