Description
Technical Field
[0001] The utility model relates to the technical field of bathroom products, and in particular to a button structure and a drain valve for preventing accidental touches. Background Art
[0002] like Figure 1 , Figure 2 As shown, the drainage button of the existing drainage valve usually includes a full-row button, a half-row button, a buckle seat and a button seat. The full-row button and the half-row button are installed on the buckle seat, and the buckle seat is assembled into the button seat. The buckle seat is driven to move by pressing the first button and the second button to drive the drainage. The pressing strokes of the full-row button and the half-row button are different, so that the movement strokes of the buckle seat are inconsistent to distinguish between the half-row and full-row functions. However, when pressing the half-row button to drive the half-row function, it is very easy to accidentally touch the full-row button (the half-row button panel is usually very small), resulting in the mistaken driving of the full-row function and causing a waste of water resources.
[0003] In view of this, the inventor of the present application invented a button structure and a drain valve that can prevent accidental touches. Utility Model Content
[0004] The utility model aims to provide a key structure and a drainage valve which are simple in structure and reasonably designed and can prevent accidental touching of another key function.
[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a button structure for preventing accidental touch, including a button body, a first button movably arranged on the button body, and a second button, the first button having a limit member that cooperates with it, when the first button is in the initial position, the limit member gives way to the second button, when the first button is pressed to complete its pressing stroke to the driving position, the limit member moves to the limited position and limits the second button.
[0006] Furthermore, the first button includes a first limiting surface, and when the first button is pressed until the first limiting surface abuts against the button body, the first button moves to the driving position.
[0007] Furthermore, the first button is provided with an assembly groove, and the limiting member is movably assembled in the assembly groove.
[0008] Furthermore, the limiting member is a slider, and the slider is slidably matched with the first button through an inclined sliding structure. When the first button is pressed to the driving position, the slider moves along the sliding structure to the limited position.
[0009] Furthermore, a return spring is provided between the slider and the first button, and the slider protrudes from the first limiting surface. When the first button is pressed until the slider abuts against the button body, and when the first button is continued to be pressed until the first limiting surface abuts against the button body, the slider moves along the sliding structure to the limited position, and after the pressing is released, the slider is reset under the action of the return spring.
[0010] Furthermore, the sliding structure is a sliding groove and ribs that slide together. When the first button is pressed and moved until the slider abuts against the button body, and when the first button is continued to be pressed until the first limit surface abuts against the button body, the slider moves to the limited position through the sliding cooperation between the sliding groove and the ribs to limit the second button.
[0011] Furthermore, the limiting member is a swing block, and when the first button is pressed to the driving position, the swing block swings to the limited position.
[0012] Furthermore, the pendulum block is rotatably connected to the first button via a rotating shaft, and the pendulum block has a driving inclined surface protruding from the first limiting surface. The first button is pressed until one side of the driving inclined surface abuts against the button body, and the first button is continued to be pressed until the first limiting surface abuts against the button body, so that the pendulum block swings along the rotating shaft until the driving inclined surface fits against the button body, and then the pendulum block swings to the limited position. The side wall of the pendulum block is provided with a limiting step, and when the pendulum block swings to the limited position, the limiting step limits the second button.
[0013] Furthermore, the button body includes a button seat and a buckle seat movably cooperated with the button seat, the first button and the second button are assembled on the buckle seat, and the first button is movably cooperated with the button seat, pressing the first button or the second button drives the buckle seat to move to realize the driving function of the button structure, when the first button is pressed to the driving position, the limit member is located at the limited position and limits the movement of the buckle seat and thus limits the second button, when the first button is in the initial position, the limit member is located at the initial position and releases the restriction on the movement of the buckle seat and thus gives way to the second button.
[0014] A drain valve comprises the above-mentioned button structure for preventing accidental touch, wherein the first button is a half-drain button, the second button is a full-drain button, and the pressing stroke of the half-drain button is smaller than the pressing stroke of the full-drain button.
[0015] After adopting the above technical solution, the utility model has the following advantages compared with the prior art:
[0016] The button structure for preventing accidental touches of the utility model, by setting a limiter linked with the first button, limits the second button when the first button is pressed to avoid accidental driving of the second button; when the first button is not pressed, the limiter gives way to the second button and does not affect the normal use of the second button. The overall structure is simple and reasonable, and the design is novel and ingenious. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0033] It should be noted that in the present invention, the terms "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element of the present invention must have a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0034] Example 1
[0035] Cooperate Figures 3 to 6 As shown, the utility model discloses a button structure for preventing accidental touch, including a button body 10, a first button 20 and a second button 30 movably arranged on the button body 10, the pressing stroke of the first button 20 is smaller than the pressing stroke of the second button 30, the first button 20 has a limit member cooperating therewith, when the first button 20 is in the initial position, the limit member gives way to the second button 30, when the first button 20 is pressed to complete its pressing stroke to the driving position, the limit member moves to the limited position and limits the second button 30.
[0036] The key structure includes two driving keys, a first key 20 and a second key 30. Pressing the two keys to complete their pressing strokes corresponds to completing their driving functions. The pressing stroke of the first key 20 is smaller than the pressing stroke of the second key 30, that is, pressing the second key 30 requires a larger pressing stroke to realize its driving function. By setting a limiter that cooperates with the first key 20, when the first key 20 is pressed, the limiter moves to a limited position to limit the second key 30. In this way, even if the second key 30 is accidentally touched when the first key 20 is pressed and moves with it, when the first key 20 completes the pressing stroke to its driving position, the second key 30 also moves the stroke. However, due to the limiting effect of the limiter, the second key 30 can only move to this position at most, and cannot reach the pressing stroke of the corresponding second key 30, thereby effectively avoiding the second key 30 being accidentally touched when the first key 20 is pressed and the corresponding function of the second key 30 is accidentally driven. When the first button 20 is located at the initial position, the limiting member gives way to the second button 30 , so that when the second button 30 is pressed alone, its pressing stroke can still be completed (without the limiting member) to complete the driving function of the second button 30 .
[0037] Among them, the button body 10 includes a button seat 11 and a buckle seat 12 that movably cooperates with the button seat 11. The first button 20 and the second button 30 are assembled on the buckle seat 12. Pressing the first button 20 or the second button 30 drives the buckle seat 12 to move to realize the driving function of the button structure.
[0038] The first button 20 and the second button 30 are both mounted on the buckle seat 12. Pressing the first button 20 and the second button 30 causes the buckle seat 12 to move accordingly. The first button 20 and the second button 30 drive functions through the movement of the buckle seat 12. Different pressing strokes cause different movement strokes of the buckle seat 12 to drive different functions. A matching limiting structure is provided between the first button 20 and the buckle seat 12 so that the buckle seat 12 can move with the first button 20. In addition, an elastic reset member (usually a compression spring) is provided between the buckle seat 12 and the button for resetting the buckle seat 12, the first button 20, and the second button 30. The above-mentioned matching of the first button 20, the second button 30, the buckle seat 12 and the button seat 11 can adopt an existing structure, such as a drainage button of a drainage valve with a full row of buttons or a half row of buttons. Among them, when the first button 20 is pressed to the driving position, the limit member is located at the limited position and limits the movement of the buckle seat 12 and thus limits the second button 30. When the first button 20 is in the initial position, the limit member is located at the initial position and releases the restriction on the movement of the buckle seat 12 and thus gives way to the second button 30.
[0039] The first button 20 includes a first limiting surface 21. When the first button 20 is pressed until the first limiting surface 21 abuts against the button body 10, the first button 20 moves to the driving position. The first button 20, the second button 30 and the buckle seat 12 are all assembled in the button seat 11. Pressing the first button 20 drives the buckle seat 12 to move accordingly. When the first limiting surface 21 abuts against the button seat 11, the first button 20 completes its pressing stroke and is now in its driving position. In this embodiment, an assembly groove 22 is provided at the first limiting surface 21 of the first button 20, and the limiting member is movably assembled in the assembly groove 22. By providing the assembly groove 22 to install the limiting member, the structure can be more compact.
[0040] In this embodiment, the limiting member is a slider 40, and the slider 40 slides with the first button 20 through an inclined sliding structure. When the first button 20 is pressed to the driving position, the slider 40 moves along the sliding structure to the limited position.
[0041] The slider 40 is assembled in the assembly groove 22 and slides with the first button 20 through an inclined sliding structure. When the first button 20 is in the initial position, there is a clearance gap 23 between the slider 40 and the buckle seat 12. When the first button 20 is pressed to the driving position, the slider 40 slides along the inclined sliding structure relative to the first button 20, thereby crossing the above-mentioned clearance gap 23 to reach a limited position (partially located below the second button 30) to limit the second button 30 (actually limiting the movement of the buckle seat 12 to restrict the buckle seat 12 from continuing to move), thereby preventing the second button 30 from continuing to move.
[0042] Specifically, a return spring 41 is provided between the slider 40 and the first button 20, and the slider 40 protrudes from the first limiting surface 21. The first button 20 is pressed until the slider 40 is against the button body 10. When the first button 20 is continued to be pressed until the first limiting surface 21 is against the button body 10, the slider 40 moves along the sliding structure to the limited position.
[0043] The sliding structure is a sliding groove 42 and a rib 43 that are slidably matched. The first button 20 can be provided with a sliding groove 42 or a rib 43, and the corresponding slider 40 is a matching rib 43 or a sliding groove 42. One end of the reset spring 41 abuts in the assembly groove 22, and the other end abuts against the slider 40. When the first button 20 is in the initial position, the slider 40 is pushed open by the reset spring 41, so that the end face of the slider 40 protrudes from the first limiting surface 21. When the first button 20 is pressed, the slider 40 moves with the first button 20 until the slider 40 abuts against the button seat 11 (there is no relative movement between the slider 40 and the first button 20 during this process). Then, the first button 20 is continuously pressed, and the first button 20 continues to move, and the slider 40 slides along the sliding structure relative to the first button 20 to a limited position, that is, located below the second button 30 to limit it. After the force of pressing the first button 20 disappears, the first button 20 is reset, and the slider 40 slides in the opposite direction along the sliding structure under the action of the reset spring 41 to reset, giving way to the second button 30 .
[0044] The utility model also discloses a drain valve, including the above-mentioned button structure, the entire button structure is a drain button of the drain valve, the first button 20 is a half-drain button, and the second button 30 is a full-drain button. Pressing the first button 20 realizes the half-drain function of the drain valve, and the limiting member can limit the second button 30 at the same time, avoiding the waste of water resources by opening the full-drain function of the drain valve; pressing the second button 30 directly opens the full-drain function of the drain valve.
[0045] Example 2
[0046] Cooperate Figures 7 to 9As shown, the difference between this embodiment and embodiment 1 is mainly that the design of the limiter is different. In this embodiment, the limiter is a swing block 50. When the first button 20 is pressed to the driving position, the swing block 50 swings to the limited position. The swing block 50 swings with the movement of the first button 20. When the first button 20 reaches the driving position, the swing block 50 also swings to the limited position, that is, the second button 30 is limited.
[0047] Specifically, the pendulum block 50 is rotatably connected to the first button 20 via a rotating shaft 51. The pendulum block 50 has a driving inclined surface 52 protruding from the first limiting surface 21. The first button 20 is pressed until one side of the driving inclined surface 52 abuts against the button body 10. The first button 20 is continued to be pressed until the first limiting surface 21 abuts against the button body 10. When the pendulum block 50 swings along the rotating shaft 51 until the driving inclined surface 52 fits against the button body 10, the pendulum block 50 swings to the limited position.
[0048] One end of the pendulum block 50 is assembled in the assembly groove 22 of the first button 20 through the rotating shaft 51, and the other end extends out of the assembly groove 22 and its end surface (driving inclined surface 52) is higher than the first limiting surface 21. When the first button 20 is in the initial position, there is a clearance gap 23 between the pendulum block 50 and the buckle seat 12; when the first button 20 is pressed, the pendulum block 50 moves with the first button 20 until one side of the driving inclined surface 52 abuts against the button seat 11 (there is no relative movement between the pendulum block 50 and the first button 20 during this process). Then, the first button 20 is continuously pressed, and the first button 20 continues to move, so that the swing block 50 swings along the rotating shaft 51 (the contact point between the swing block 50 and the button seat 11 is not concentric with the rotating shaft 51, and a deflection force will be generated after the force is applied to make the swing block 50 swing) and crosses the clearance gap 23 to the limited position (the driving inclined surface 52 is in contact with the button seat 11), and the second button 30 is limited; when the force of pressing the first button 20 disappears, the first button 20 is reset, and the swing block 50 swings and resets under its own gravity, making way for the second button 30. The side wall of the swing block 50 is provided with a limiting step 53. When the swing block 52 swings to the limited position, the limiting step 53 limits the second button 30. Specifically, the limiting step 53 limits the buckle seat 12 and then the second button.
[0049] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
