Description

Technical Field

[0001] This utility model relates to a switch, specifically a button-type cabinet door trigger switch with concealed button. Background Technology

[0002] Cabinet door trigger switches are common components in furniture and household appliances, widely used to automatically open and close cabinet doors or trigger other functions. In traditional designs, these switches typically feature a protruding button, with the button cap directly exposed on the cabinet door or body surface, requiring the user to manually press to activate the switch. However, this design has revealed some significant drawbacks and limitations in practical use.

[0003] 1. Difficult to clean: The protruding design of the keycaps means they are not flush with the cabinet door surface, making them prone to accumulating dust, grease, and other impurities during use, especially in environments like kitchens. For example, grease, food residue, and water stains can accumulate in the gaps around the keys, making them difficult to remove completely during cleaning. This not only affects the cleanliness of the product but may also damage the internal circuitry or spring mechanism of the keys.

[0004] 2. Accidental Operation Issues: During routine cleaning of the cabinet door surface, users typically wipe the door with a damp cloth or other tools. If the buttons are designed with exposed keycaps, the wiping action can easily cause unintentional contact with the keycaps, leading to accidental activation of the switch and resulting in the cabinet door opening or closing unexpectedly. This accidental operation not only increases user inconvenience but may also affect the safety of internal devices or items. For example, a sudden opening of the cabinet door during cleaning could cause internal items to fall out or be damaged.

[0005] 3. Poor Aesthetics: As consumers' demands for home product design increase, the traditional exposed keycap switch design disrupts the overall smoothness and simplicity of cabinet doors, failing to meet modern families' needs for integrated, aesthetically pleasing, and minimalist styles. The protruding buttons create a visually jarring effect, clashing with the overall cabinet design and affecting the furniture's overall aesthetic appeal. Therefore, further improvements are necessary. Utility Model Content

[0007] The purpose of this utility model is achieved in the following way: a button-type cabinet door trigger switch, which includes a mounting base embedded in the cabinet body, the side end of the mounting base is covered with a decorative panel, and the front end is covered with a cover plate.

[0008] An external guide hole is formed through the cover plate, and the switch button is installed in the external guide hole. The outer end face of the switch button is set lower than the end face of the cover plate.

[0009] Furthermore, the cover plate has an outer buckle extending rearward from its back side, and correspondingly, the mounting base is provided with an inner buckle. The outer buckle extends into the mounting base and hooks with the inner buckle, thus defining the relative position between the cover plate and the mounting base.

[0010] Furthermore, a spring groove is provided on the back of the cover plate, and a return spring is installed in the spring groove. The inner end of the return spring presses against the mounting base, and the return spring generates an elastic thrust, pushing the cover plate to pop outward continuously.

[0011] Furthermore, the front end face of the mounting base is also provided with a fixing panel, the cover plate covers the fixing panel, the fixing panel is provided with an inner guide hole, the inner guide hole and the outer guide hole are concentrically arranged, and the switch button passes through the inner guide hole and enters the outer guide hole.

[0012] Furthermore, the fixed panel is also provided with an inlet groove, through which the outer buckle passes into the mounting base and connects with the inner buckle.

[0013] Furthermore, the side ports of the mounting base are recessed with grooves, and the decorative panel is provided with a raised sliding platform at the corresponding position. The sliding platform is slidably inserted into the groove to realize the installation and removal of the decorative panel and the mounting base.

[0014] Furthermore, the outer cylindrical surface of the mounting base is provided with an undercut, which hooks onto the groove wall of the mounting hole.

[0015] Furthermore: the mounting base has a hollow interior forming a receiving cavity, and a main control circuit board is installed inside the receiving cavity. A micro switch and a switch button are installed on the main control circuit board.

[0016] The beneficial effects of this utility model are: 1. Simple structure, low production cost, and improved market competitiveness.

[0017] 2. The switch button of this utility model is hidden inside the cover plate, and the outer end face of the button is lower than the end face of the cover plate, so that the button remains flat with the surface of the cover plate when not in operation. This hidden design effectively avoids the problem of users accidentally triggering the button due to wiping action when cleaning the cabinet door, thereby reducing the occurrence of accidental operation.

[0018] 3. The concealed button design keeps the cabinet door surface clean and flat, and the decorative design of the cover plate blends naturally with the cabinet appearance, avoiding the visual abruptness caused by the exposed traditional key caps.

[0019] 4. The buttons of this utility model are hidden inside the cover plate and are not directly exposed to the outside world, which effectively avoids the intrusion of dust, oil and moisture, and extends the service life of the buttons and internal circuit components.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings. A button-type cabinet door trigger switch includes a mounting base 1 embedded in the cabinet body, a decorative panel 2 covering the side end of the mounting base 1, and a cover plate 3 covering the front end of the mounting base 1;

[0025] The cover plate 3 has an outer guide hole 31 extending through its body. The switch button 6 is installed in the outer guide hole 31, and the outer end face of the switch button 6 is set lower than the end face of the cover plate 3.

[0026] In one embodiment: the cover plate 3 has an outer buckle 32 extending rearward from the back side, and correspondingly, the mounting base 1 is provided with an inner buckle 11. The outer buckle 32 extends into the mounting base 1 and hooks with the inner buckle 11, limiting the relative position between the cover plate 3 and the mounting base 1.

[0027] In one embodiment: a spring groove 33 is also provided on the back of the cover plate 3, and a reset spring 34 is installed in the spring groove 33. The inner end of the reset spring 34 presses against the mounting base 1, and the reset spring 34 generates an elastic thrust, pushing the cover plate 3 to pop outward continuously.

[0028] In one embodiment: the front end face of the mounting base 1 is further provided with a fixing panel 4, the cover plate 3 covers the fixing panel 4, the fixing panel 4 is provided with an inner guide hole 41, the inner guide hole 41 and the outer guide hole 31 are concentrically arranged, and the switch button 6 passes through the inner guide hole 41 and enters the outer guide hole 31.

[0029] In one embodiment: the fixed panel 4 is also provided with an inlet groove 42, through which the outer buckle 32 passes into the mounting base 1 and is hooked and connected with the inner buckle 11.

[0030] In one embodiment: the side ports of the mounting base 1 are recessed with grooves 12, and the decorative panel 2 is provided with a protruding slide 21 at the corresponding position. The slide 21 is slidably inserted into the groove 12 to realize the installation and removal of the decorative panel 2 and the mounting base 1.

[0031] In one embodiment: the outer cylindrical surface of the mounting base 1 is provided with an inverted buckle 13, which is hooked onto the groove wall of the mounting hole.

[0032] In one embodiment: the mounting base 1 is hollow to form a receiving cavity 14, and a main control circuit board 5 is installed in the receiving cavity 14. A micro switch 51 is installed on the main control circuit board 5 and connected to the switch button 6.

[0033] Working principle: The switch button 6 of this invention is installed in the outer guide hole 31 on the cover plate 3, and its position is further defined by the inner guide hole 41, making the operation of the switch button 6 more precise. Meanwhile, the outer end face of the switch button 6 is designed to be lower than the end face of the cover plate 3, so that the button is hidden in the non-operational state, preventing the button from being directly exposed to the external environment. When the user needs to operate it, by pressing the switch button 6, the button directly contacts the micro switch 51 on the internal main control circuit board 5, completing the triggering of the electrical signal.

[0034] Compared with traditional technology, this button concealment design reduces direct external interference to the buttons, improves the device's resistance to dirt, and avoids accidental operation by users during cleaning.

[0035] Furthermore, this case also features an outer guide hole 31 and an inner guide hole 41, both designed concentrically to provide sufficient guide space for the case, thereby making the button press trigger more precise and the operation feel more stable and smooth.

[0036] It should be noted that a spring groove 33 is provided on the back of the cover plate 3, and a return spring 34 is installed therein. Its inner end presses against the mounting base 1, and its outer end acts on the cover plate 3. When the user presses the cover plate 3 through the cabinet door to trigger the switch, the return spring 34 is compressed and stores elastic potential energy. After the user releases the button, the return spring 34 releases the elastic thrust, pushing the cover plate 3 and the button back to their initial positions, preparing for the next trigger.

[0037] This spring-return structure ensures that the cover and buttons always return to their initial positions, preventing button jamming or misalignment. Simultaneously, the spring-return structure provides sufficient actuation travel for the cabinet door and maintains the long-term stability of the button's dynamic structure, extending its service life.

[0038] It should be noted that in this case, a cavity 14 is formed inside the mounting base 1, and a main control circuit board 5 is installed inside the cavity. Through a reasonable layout, the main control circuit board electrically connects the switch button 6 to the micro switch 51. The button operation triggers the micro switch 51, and the electrical signal is transmitted to the control system through the main control circuit board, realizing the opening and closing of the cabinet door or triggering other electrical control functions.

[0039] In order to facilitate the connection between this device and the mounting holes on the cabinet, in this case, a buckle 13 is provided on the outer column surface of the mounting base 1. When the mounting base is inserted into the mounting hole, the buckle is fixed to the groove wall of the mounting hole of the cabinet, thereby ensuring that the entire switch system is firmly installed inside the cabinet. Therefore, this device can also achieve screwless installation, thereby improving the installation and disassembly efficiency of the device.

[0040] In summary, this invention achieves precision, durability, and ease of cleaning in button-triggered cabinet door opening and closing by concealing the button. These technical advantages make this invention far superior to traditional cabinet door trigger switches in terms of practicality and user experience, giving it significant market competitiveness and application value.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
