[0001] This utility model relates to the field of massage equipment technology, and in particular to a button structure and a massager. Background Technology

[0002] When using eye massagers and similar devices, users typically need to adjust them by blind pressing. Most existing eye massagers use a combined button design. The structure of the combined buttons, combined with the difficulty for users to directly observe their positions, easily leads to accidental button presses during adjustment. This affects the normal user experience and operational accuracy, causing considerable inconvenience to users. Utility Model Content

[0003] The main purpose of this invention is to propose a button structure and a massager, aiming to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, this utility model proposes a button structure, comprising:

[0005] The fastener is provided with a first clearance hole;

[0006] A first button has a fixed end and a movable end. The fixed end is fixedly connected to the fixing member, and the movable end protrudes from the first clearance hole and is movably connected to the fixing member so as to move within the first clearance hole when pressed. A second clearance hole is provided on the movable end near the fixed end; and

[0007] The second button protrudes partially from the second clearance hole and is clearance-fitted with the second clearance hole. The second button is movably connected to the fixed end so that it can move axially along the second clearance hole when pressed.

[0008] In one embodiment, the button structure further includes a first elastic body, one end of which is fixedly connected to the movable end, and the other end of which is fixedly connected to the fixing member.

[0009] In one embodiment, the button structure further includes a second elastic body, one end of which is fixedly connected to the fixed end, and the other end of which is fixedly connected to the second button.

[0010] In one embodiment, the second elastomer is connected to the fixed end by heat fusion.

[0011] In one embodiment, the first elastomer and the fixed end are respectively fastened to the fixing member by fasteners.

[0012] In one embodiment, the fixed end and the second elastic body are connected to the fixing member via the same fastener.

[0013] In one embodiment, the outer wall of the second button is provided with a rim, the rim being located at one end of the first button away from the pressed end and spaced apart from the first button, and the outer circumferential dimension of the rim is not less than the diameter of the second clearance hole.

[0014] In one embodiment, the first button is provided with a first thinning groove, which is located on the side of the second clearance hole away from the fixed end; and / or, the first elastomer is provided with a second thinning groove.

[0015] In one embodiment, the button structure further includes a third button, which includes a third button and two third elastic bodies. The fixing member is also provided with a third clearance hole. The third button protrudes from the third clearance hole. One end of each third elastic body is fixedly connected to the third button, and the other end is fixedly connected to the fixing member. The two third elastic bodies are arranged in a centrally symmetrical manner with respect to the center of the third button.

[0016] This utility model also proposes a massager, including the button structure described above.

[0017] In the technical solution of the button structure proposed in this utility model, the integrated button is divided into two parts: a first button and a second button. A second clearance hole is provided at the fixed end of the first button to avoid the second button, and the second button protrudes from the second clearance hole to facilitate user pressing. The second button and the second clearance hole are designed with a clearance fit. The second button is movably connected to the fixed end. When the movable end is pressed, the movable end swings within the first clearance hole. Since the second button and the first button are independent of each other, and the second button and the second clearance hole are in a clearance fit, the movable end will not rub against the second button. When the second button is pressed, the second button will also move independently and will not be linked with the first button, thereby eliminating accidental touches. Moreover, since the second button is embedded in the first button, the user can easily distinguish between the first button and the second button when pressing blindly, which can also prevent accidental touches. In addition, the second button is connected to the first button and then connected to the fixing component as a whole, which can simplify the connection structure in the button structure and also help to reduce the overall size of the button structure.

[0030] This technical solution proposes a button structure, including:

[0031] The fastener 100 is provided with a first clearance hole 110;

[0032] The first button 200 has a fixed end 210 and a movable end 220. The fixed end 210 is fixedly connected to the fixing member 100. The movable end 220 protrudes from the first clearance hole 110 and is movably connected to the fixing member 100 so that it can move within the first clearance hole 110 when pressed. A second clearance hole 230 is provided on the movable end 220 near the fixed end 210.

[0033] The second button 300 protrudes partially from the second clearance hole 230 and is clearance-fitted with the second clearance hole 230. The second button 300 is movably connected to the fixed end 210 to move along the axial direction of the second clearance hole 230.

[0034] In the technical solution of the button structure proposed in this utility model, the integrated button is divided into two parts: a first button 200 and a second button 300. A second clearance hole 230 is provided at the fixed end 210 of the first button 200 to accommodate the second button 300, and the second button 300 protrudes from the second clearance hole 230 to facilitate user pressing. The second button 300 and the second clearance hole 230 are designed with a clearance fit. The second button 300 is movably connected to the fixed end 210. When the movable end 220 is pressed, the movable end 220 swings within the first clearance hole 110. Since the second button 300 and the first button 200 are independent of each other, and the second button 300... The second clearance hole 230 is clearance-fitted with the second button 300, so the movable end 220 will not rub against the second button 300. When the second button 300 is pressed, the second button 300 will also move independently and will not be linked with the first button 200, thus eliminating accidental touches. Moreover, since the second button 300 is embedded in the first button 200, the user can easily distinguish between the first button 200 and the second button 300 when pressing blindly, which can also prevent accidental touches. In addition, the second button 300 is connected to the first button 200 and then connected to the fixing member 100 as a whole, which simplifies the connection structure in the button structure and also helps to reduce the overall size of the button structure.

[0035] Specifically, the button structure in this embodiment can be applied to an eye massager, such as... Figure 1 The button structure includes a fixing member 100, which can be connected to the housing 10 of the eye massager to fix the button structure as a whole onto the housing 10. The fixing member 100 has a first clearance hole 110, which can be an elongated oval shape. A first button 200 is provided on the fixing member 100, with a portion of the first button 200 protruding from the first clearance hole 110 to facilitate easier pressing of the first button 200 by the user and to make it easier to locate the first button 200 when blindly pressing. Specifically, as... Figure 3 and Figure 5As shown, the first button 200 has two main parts: a fixed end 210 and a movable end 220. The fixed end 210 is fixedly connected to the fixing member 100. The fixed end 210 can be connected to the side of the fixing member 100 facing the housing 10 by means of screwing or gluing. The movable end 220 has an integrally formed pressing area (the part pressed by the user). That is, the movable end 220 includes the part of the first button 200 that protrudes through the first clearance hole 110. The shape of the protruding part can be adapted to the first clearance hole 110, and the size is smaller than the diameter of the first clearance hole 110. The movable end 220 can be in a free state. In the free state, when the protruding part of the movable end 220 is pressed, the movable end 220 can move towards the housing 10. The housing 10 swings to one side to trigger a switch located inside the housing 10. After pressing, the first button 200 returns to its state before pressing. It can be understood that the pressing area of ​​the first button 200 (the part directly pressed by the user) exists independently of the movable end 220. The pressing area can be integrally formed on the movable end 220 or assembled with it. The pressing area is fixedly connected to the movable end 220 and extends through the first clearance hole 110. When the user presses the pressing area, it acts on the movable end 220. The pressing area and the movable end 220 move synchronously along the axial direction of the first clearance hole 110. When the pressure on the pressing area is released, the movable end 220 and the pressing area reset. Figure 3 Correspondingly, a circuit board 20 is provided on the housing 10. The pressing area can touch the contacts on the circuit board 20 to trigger a control signal. In addition, a second clearance hole 230 is provided on the movable end 220 near the fixed end 210. The second clearance hole 230 can be a circular through hole. The second button 300 extends into the second clearance hole 230 and protrudes from the second clearance hole 230. The shape of the part of the second button 300 extending into the second clearance hole 230 is adapted to the shape of the second clearance hole 230 and is clearance-fitted with the second clearance hole 230. This is also to facilitate blind pressing and confirm the position of the second button 300, and to make the second button 300 easier to press. When pressed, the second button 300 can move axially along the second clearance hole 230. In addition, the second button 300 can also be movably connected to the fixed end 210 through a cantilever structure made of elastic material to support the second button 300 and allow the second button 300 to move relative to the fixed member 100. Similarly, a contact point opposite to the position of the second button 300 can also be provided on the circuit board 20, and a control signal is triggered by pressing the second button 300. It can be understood that the setting of the pressing area of ​​the second button 300 is the same as that of the first button 200, and will not be described in detail here.

[0036] When the user presses the pressing area on the first button 200, the pressing area and the movable end 220 move synchronously towards the circuit board 20. The first button 200 and the second button 300 are separate structures. The second button 300 is fixed because it is connected to the fixed end 210. Therefore, the first button 200 will not drive the second button 300 to move. The second clearance hole 230 is set close to the fixed end 210, and the displacement of the area where the second clearance hole 230 is located is limited, which also reduces the possibility of the first button 200 and the second button 300 rubbing against each other. When the second button 300 is pressed, the second button 300 can move within the second clearance hole 230 under the action of the elastic element. The second button 300 also moves independently relative to the first button 200. There is an active gap between the second button 300 and the second clearance hole 230. During the movement, it will not rub against the first button 200. Therefore, the linkage between the first button 200 and the second button 300 can be prevented, reducing the possibility of accidental touch. Furthermore, the second button 300 is embedded within the first button 200. When the user presses blindly, the significant difference in shape and position between the first button 200 and the second button 300 makes them easy to distinguish and prevents accidental touches. Simultaneously, the second button 300, after being connected to the first button 200, is integrally connected to the fixing member 100. This simplifies assembly complexity, reduces the connecting structure within the button design, and helps reduce the overall size of the button structure, making it more suitable for use in small devices such as eye massagers. In summary, the above-described structural design of the first button 200 and the second button 300 improves the user's operating experience when blindly adjusting the buttons, reduces the risk of accidental touches, and enhances the practicality and reliability of the device.

[0037] like Figure 2 and Figure 5 As shown, in another embodiment of this utility model, the button structure further includes a first elastic body 250. The first elastic body 250 can be a cantilever structure or other elastic element made of an elastic material. One end of the first elastic body 250 is connected to the end of the movable end 220 away from the fixed end 210, and the other end is connected to the fixed member 100 by means of screwing or bonding. The first elastic body 250 itself can be bent and deformed. When the user presses the pressing area, the movable end 220 bends and deforms, and along the... Figure 3 When the button moves downwards, the pressing area contacts the circuit board 20 below, and the first elastic body 250 deforms. When released, the first elastic body 250 drives the movable end 220 and the pressing area back to the initial position. During this process, the first elastic body 250 can provide support for the movable end 220, ensuring that the movable end 220 and the pressing area can be reset normally, and can also improve the reliability of the connection between the first button 200 and the fixing member 100.

[0038] like Figure 2 and Figure 5 As shown, in another embodiment of the present invention, the button structure further includes a second elastic body 310, one end of which is fixedly connected to the fixed end 210, and the other end is fixedly connected to the second button 300. The second button 300 has a second elastic body 310 connected to its side wall. The second elastic body 310 can have a similar structure to the first elastic body 250. One end of the second elastic body 310 is fixedly connected to the second button 300, and the other end is connected to the fixed end 210 of the first button 200. When the user presses the pressing area on the second button 300, the pressing area moves downward as a whole within the second clearance hole 230. The second elastic body 310 deforms under force. After being released, the second elastic body 310 returns to its original shape, causing the second button 300 to return to its initial position. In addition, to simplify the process, the second button 300 and the second elastic body 310 can be made of the same material and integrally molded. To ensure the stability of the second button 300 during movement, two second elastic bodies 310 can be provided. The two second elastic bodies 310 can be symmetrically arranged relative to the second button 300, which can ensure the force balance of the second button 300 and ensure the pressing feel.

[0039] To simplify the assembly process of the button structure, in one embodiment, the second elastic body 310 and the fixed end 210 are connected by heat fusion. Specifically, a heat fusion column can be provided at the position where the fixed end 210 connects to the second elastic body 310. The heat fusion column is made of thermoplastic plastic, and a heat fusion hole can be opened at the end of the second elastic body 310. The heat fusion hole can be fitted onto the heat fusion column, and then the heat fusion column is heated using a heat fusion device to bond the end of the heat fusion column to the periphery of the heat fusion hole. After it cools and solidifies, the second elastic body 310 and the fixed end 210 are heat fused together. In this way, not only is the connection structure between the first button 200 and the second button 300 simplified, and production efficiency can be improved, but the connection between the first button 200 and the second button 300 is also stable and reliable, ensuring that the second button 300 will not loosen during long-term use, thus guaranteeing the stability and service life of the button structure.

[0040] To facilitate the assembly of the button structure, in one embodiment of this utility model, the first elastic body 250 and the fixed end 210 are respectively fastened to the fixing member 100 by fasteners. The fasteners can be components such as screws. The first elastic body 250 extends around the outer wall of the first button 200 and is spaced apart from the first button 200. A lug can be provided on the side of the first elastic body 250 opposite to the first button 200, and a through hole is provided on the lug. The fastener passes through the through hole and is fastened to the fixing member 100. Additionally, a lug can also be provided on the fixed end 210, and a through hole is also provided on the lug. The fastener passes through the through hole and is fastened to the fixing member 100. By using fasteners, the connection strength and stability between the first button 200 and the fixing member 100 are improved, and the first button 200 is easier to disassemble and assemble.

[0041] like Figure 4 As shown, in one embodiment, the fixed end 210 and the second elastic body 310 are connected to the fixing member 100 by the same fastener. Specifically, a through hole is also provided on the end of the second elastic body 310 that connects to the fixed end 210. The fastener can pass through the through hole on the second elastic body 310 and the through hole of the lug on the fixed end 210 in sequence and finally be fastened to the fixing member 100. While assembling the first button 200 and the second button 300 together, both are also fixed to the fixing member 100. This achieves the synchronous installation and fixing of the first button 200 and the second button 300, which not only simplifies the installation steps but also simplifies the overall structure of the button, making the button structure more compact and saving space.

[0042] like Figure 3 In one embodiment of the present invention, a perimeter 320 is provided on the outer side wall of the second button 300. The perimeter 320 is located at one end of the second button 300 away from the pressed end and is spaced apart from the first button 200. The outer perimeter of the perimeter 320 is not less than the diameter of the second clearance hole 230. In this design, the edging 320 is integrally formed on the outer peripheral wall of the second button 300 and extends around the second button 300. The second button 300 has a pressing end and a bottom end opposite to the pressing end. The edging 320 is located on the outer peripheral wall of the second button 300 near the bottom end, that is, the edging 320 is located on the side of the first button 200 facing the circuit board 20. In addition, the size of the edging 320 is larger than the diameter of the second clearance hole 230, so that the edging 320 can cover the gap between the second button 300 and the second clearance hole 230. This design can prevent the circuit board 20 or light inside the housing 10 from being exposed through the gap, thereby improving the appearance and visual effect of the product.

[0043] like Figure 4In one embodiment of this utility model, the first button 200 is provided with a first thinning groove 240, which is located on the side of the second clearance hole 230 away from the fixed end 210. In this solution, the first thinning groove 240 can be formed on the side of the first button 200 facing the circuit board 20 and extends along the width direction of the first button 200. The first thinning groove 240 is located in the area between the second clearance hole 230 and the end of the movable end 220 away from the fixed end 210, thereby reducing the structural strength of this area. When the first button 200 is pressed... When the pressing area on button 200 is located, the position of the first thinning groove 240 is more prone to bending and deformation. With a fixed pressing stroke in the pressing area, the swing stroke of the end of the movable end 220 furthest from the fixed end 210 will increase, while the swing stroke at the location of the second clearance hole 230 will decrease. This further reduces the possibility of rubbing between the area of ​​the second clearance hole 230 and the second button 300. Furthermore, the thinning groove makes the first button 200 easier to press, reducing the required pressing force and improving the pressing feel. Similarly, a second thinning groove 251 is provided on the first elastic body 250. This second thinning groove 251 can be set perpendicular to the extending direction of the first elastic body 250, which also makes the first elastic body 250 easier to deform, further improving the pressing feel.

[0044] like Figure 1 and Figure 2In another embodiment of this utility model, the button structure further includes a third button 400. A third clearance hole 120, independent of the first clearance hole 110, can be provided on the fixing member 100. The third button 300 is also provided with a pressing area. The pressing area of ​​the third button 300 is the same as that of the first button 200. The third clearance hole 120 is used to accommodate the pressing area of ​​the third button 400. The pressing area of ​​the third button 300 can partially protrude from the third clearance hole 120 to facilitate pressing. When pressed, the third button 400 can move along the axial direction of the third clearance hole 120. The pressing area of ​​the third button 400 can be used to press another contact point provided on the circuit board 20 to trigger a third type of control signal. The third button 400 can adopt a different shape and size from both the first button 200 and the second button 300. With this setting, the shapes and positions of the first button 200, the second button 300, and the third button 400 are all significantly different, which also facilitates blind pressing by the user. In addition, the third button 400 is connected to two third elastic bodies 410. The two third elastic bodies 410 are centrally symmetrical with respect to the center of the third button 400. When the third button 400 is pressed, both third elastic bodies 410 provide support for the third button 400. This symmetrical layout of the two third elastic bodies 410 makes the force applied to the third button 400 by the two third elastic bodies 410 during deformation more symmetrical, ensuring that the force on the third button 400 is uniform and avoiding the tilting or shaking of the button due to uneven force, thus improving the operating feel.

[0045] This utility model also proposes a massager that can be used for eye massage. The massager includes a housing 10, on which a massage head is provided for massaging the massage area. A button structure can be provided on the side wall of the housing 10 for adjusting the massage parameters. The specific structure of the button structure is as described in the above embodiments. Since this massager adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0046] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
