Description

Technical Field

[0001] This utility model relates to a button switching structure, specifically a button switching structure that can be applied to a pull-out head. Background Technology

[0002] Pull-out drawers are increasingly used in modern kitchen and bathroom fixtures, and the design of their button switching structure directly impacts the user experience. Currently, most pull-out drawer button switching structures on the market are horizontal or vertical, using a button to drive a support that pushes a central valve inside the water channel to switch between two water flow paths. However, existing switching structures have significant shortcomings, particularly the lack of timely feedback mechanisms during user operation. Specifically, when a user presses the button to switch water flow paths, the absence of corresponding audible or tactile cues makes it difficult for the user to accurately determine whether the switch has been completed. This not only reduces ease of use but also negatively impacts the overall user experience. Furthermore, existing button designs have a stiff feel during pressing, lacking cushioning, which can easily cause user fatigue after prolonged use. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, specifically a button switching structure that can provide clear switching feedback and improve the pressing feel, the purpose of this utility model is to provide a button switching structure.

[0004] This utility model is achieved through the following technical solution:

[0005] A button switching structure includes a body, on which a button for switching is disposed, the button being configured to move relative to the body to achieve switching, a mounting position being disposed on the body, and a spring being disposed at the mounting position; the movement of the button relative to the body can drive the spring to deform, and the deformation of the spring can emit an audible sound indicating that the switching is complete.

[0006] In this embodiment of the utility model, the installation position is configured as a stepped groove on the body, and the outer periphery of the spring is disposed on the stepped surface of the stepped groove; when the spring does not deform, the middle part of the spring is arched upward.

[0007] In this embodiment of the invention, the spring is a recessed spring, and the button is equipped with a pressing rod that can act on the spring.

[0008] In this embodiment of the utility model, a pressure plate is also included, which is configured to restrict the spring sheet in the installation position and can be fixedly connected to the main body.

[0009] In this embodiment of the utility model, the pressure plate is provided with a through hole in the middle, and the button can act on the spring through the through hole to make the spring make a sound; the pressure plate located on both sides of the through hole is provided with a plug-in part, and the body is provided with a slot. The plug-in part is configured to be compatible with the slot so that the pressure plate can restrict the spring in the installation position.

[0010] In this embodiment of the utility model, the button is configured such that its middle part is rotatably connected to the body, and the two ends of the button are provided with pressing parts. The body is provided with two installation positions that can be adapted to each pressing part.

[0011] In this embodiment of the utility model, two brackets are also included, each bracket being adapted to each pressing part. The bracket is configured such that its middle part can be rotatably connected to the main body, and one end of the bracket can abut against the pressing part. The pressing energy of the pressing part can drive the bracket to rotate relative to the main body. The bracket is also equipped with a reset member; the reset member is configured to enable the button and bracket to reset relative to the main body after the pressing part is depressurized.

[0012] In this embodiment of the utility model, a rotating shaft is arranged in the middle of the bracket, and a connecting groove is arranged on the body. The rotating shaft is arranged in the connecting groove so that the bracket can rotate relative to the body. The reset member is a torsion spring, which is configured to be sleeved on the outer circumference of the rotating shaft. One end of the torsion spring can abut against the bracket, and the other end of the torsion spring can abut against the body.

[0013] In this embodiment of the invention, a central bolt for switching is also included. The central bolt is movable relative to the body. A pair of mating parts are provided on the central bolt. The mating parts can engage with the other end of the bracket. The rotation of the bracket relative to the body can cause the other end of the bracket to drive the central bolt to move relative to the body under the action of the mating parts.

[0014] In this embodiment of the invention, the mating part is a notch disposed on the central bolt, and the body is provided with a connecting hole that can be adapted to the central bolt, and the central bolt can move within the connecting hole; the pressing part can only drive one of the brackets to rotate relative to the body.

[0015] This invention provides a button switching structure with the following advantages: By introducing a recessed spring into the button switching structure, the problem of lacking operational feedback sound in the prior art is solved, while simultaneously improving the tactile feedback of pressing. Specifically, the recessed spring design emits a clear "Click" sound through deformation during pressing, providing the user with clear operation confirmation. Furthermore, the elasticity of the recessed spring increases the cushioning during pressing, improving the user experience. In particular, this invention ensures the stability and repeatability of water circuit switching through the linkage design of the bracket, reset component, and central bolt, resulting in a compact and reliable overall structure.

[0016] Meanwhile, the technical solution of this utility model has high practical value and market promotion prospects in practical applications. Through the above design, users can not only obtain timely sound feedback when operating the button to switch structures, but also feel a good pressing sensation, thereby significantly improving the user experience.

[0026] Referring to the accompanying drawings, this utility model provides a button switching structure suitable for water path switching devices with pull-out heads. It optimizes the operational feedback sound and pressing feel by introducing a recessed spring. The specific embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0027] The main body 1, serving as the foundational framework of the entire structure, can also be referred to as the waterway body. It primarily houses components for the switching structure and water passages. Internally, it includes functional structures such as a stepped groove 16, a connecting groove 18, and connecting holes 15. A button 2 is positioned above the main body 1, its central portion engaging with the main body 1 via a rotatable connection. Both ends are equipped with pressing parts 3, each of which, when pressed, drives the central bolt to move in opposite directions. Below the pressing parts at both ends of the button 2 are pressing rods 4, which directly contact the recessed spring 5. These rods push the recessed spring 5 downwards during pressing, causing deformation and producing a sound. The recessed spring 5 is installed within the stepped groove 16 on the main body 1, its outer periphery fixed to the stepped surface 17 of the stepped groove 16. After installation, the recessed spring 5 is hollow, with the bottom of the stepped groove empty. In the unloaded state, the central portion of the recessed spring 5 arches upwards, forming an arc-shaped structure. When button 2 is pressed, the pressing lever 4 pushes the recessed spring 5 downward, causing it to change from a curved surface to a flat surface or a recessed shape, producing a deformation and a clear click sound. This deformation process not only provides clear operational feedback but also enhances the pressing cushioning feel through its elastic properties. When no force is applied, the recessed spring can spring back to its original position under its own action, making it easy to produce a click sound again the next time it is pressed.

[0028] The pressure plate 6 is used to retain the recessed spring 5 in its installation position, preventing it from loosening. It also prevents it from jumping out of its installation position upon rebound. A through hole 7 is provided in the center of the pressure plate 6, through which the pressing rod 4 of the button 2 acts on the recessed spring 5. Insertion parts 8 are provided on the pressure plate 6 on both sides of the through hole 7, which fit into the slots 9 on the body 1, ensuring the pressure plate 6 is firmly fixed. Through this design, the recessed spring 5 remains stable during pressing, avoiding any impact on the operational feedback due to loosening. The pressure plate 6 uses a plug-in structure for fixing, simplifying the assembly process and improving the overall structural reliability.

[0029] There are two brackets 10, each bracket 10 being adapted to a pressing part 3. The middle of each bracket 10 is rotatably connected to the connecting groove 18 of the main body 1 via a rotating shaft 11. One end of each bracket 10 abuts against the pressing part 3, and the other end abuts against the mating part 14 of the center bolt 13. When the pressing part 3 is pressed, one bracket 10 rotates relative to the main body 1, while the other bracket does not rotate relative to the main body. The rotation of the bracket 10, through the action of its other end and the mating part 14, drives the center bolt 13 to move, thereby achieving the switching of the water path direction. The technology for switching the water path using the center bolt is similar to existing technology and will not be described in detail again. The reset element is a torsion spring 12, sleeved on the outer circumference of the rotating shaft 11 of the bracket 10. One end of the torsion spring 12 abuts against the bracket 10, and the other end abuts against the main body 1. When the pressing part 3 releases force, the elastic restoring force of the torsion spring 12 causes the button 2 and the bracket 10 to automatically reset to their initial state. That is, after each press and release, the button can return to a horizontal position, improving the neatness of the button and the body (or shell). The design of the torsion spring 12 ensures the smoothness and reliability of the reset process, while reducing wear on parts.

[0030] The central throttle 13 is movable relative to the body 1 to control the switching of water channels. The central throttle 13 has a pair of notches serving as mating parts 14, which engage with the other end of the bracket 10. When the bracket 10 rotates, its other end interacts with the notches of the central throttle 13, driving the central throttle 13 to move relative to the body 1, thereby changing the direction of the water channel. The body 1 has a connecting hole 15 that matches the central throttle 13, allowing the central throttle 13 to move within the connecting hole 15, ensuring the accuracy of its movement trajectory. The range of motion of the central throttle 13 is precisely designed to guarantee the accuracy and stability of water channel switching.

[0031] When button 2 (a pressing part) is pressed, the pressing rod 4 pushes the recessed spring 5 to deform and emit a click sound, simultaneously driving a bracket 10 to rotate. The rotation of bracket 10 causes the central plug 13 to move, changing the water flow direction and allowing water to flow out from another outlet. This linkage design realizes the water flow switching function while providing timely operational feedback. After the water flow switching is completed, button 2 and bracket 10 automatically reset to their initial state through the action of torsion spring 12, ready for the next operation.

[0032] The technical solution of this utility model has high practical value in practical applications. For example, in pull-out faucets in kitchens or bathrooms, users need to frequently switch water flow modes to meet different usage needs. Traditional switching structures lack clear feedback sounds, often requiring users to repeatedly confirm whether the operation was successful, resulting in a poor user experience. This utility model solves this problem by introducing a recessed spring 5. During pressing, the deformation of the recessed spring 5 produces a clear click sound, providing users with clear operation confirmation. In addition, the elasticity of the recessed spring 5 increases the cushioning during pressing, improving the user experience. The linkage design of the bracket 10, the reset component, and the central plug 13 ensures the stability and repeatability of water flow switching, and the overall structure is compact and reliable.

[0033] The specific implementation of this utility model also includes the following details. The recessed spring 5 is made of stainless steel, possessing good elasticity and corrosion resistance, and can maintain stable performance during long-term use. The insertion part 8 of the pressure plate 6 and the slot 9 of the body 1 are interference-fitted to ensure that the pressure plate 6 will not loosen after assembly. A lubricating coating is provided between the rotating shaft 11 of the bracket 10 and the connecting groove of the body 1 to reduce frictional resistance and improve rotational efficiency. The mating part 14 of the center bolt 13 is precision-machined to ensure that the mating clearance with the bracket 10 is within a reasonable range, ensuring both sensitive operation and avoiding excessive wear. The elastic coefficient of the torsion spring 12 has been optimized through multiple tests to ensure a smooth and rapid reset process.

[0034] In summary, this utility model, by introducing a recessed spring piece 5 and combining it with the linkage mechanism of the bracket 10, the reset component, and the central bolt 13, achieves water path switching while providing clear operational feedback and a good pressing feel. This technical solution not only improves the user's operating experience but also has high practical value and market potential.
