Description

Technical Field

[0001] This invention relates to the field of wall switch technology, specifically to a stable and reliable wall switch. Background Technology

[0002] Switches are a very common device in daily life, mainly used to control the on and off of circuits. Wall switches are a type of switch installed on the wall, mainly used to control lights, which are turned on or off by pressing.

[0003] In the prior art, Chinese patent CN206697388U discloses a wall switch, aiming to provide a wall switch with stable structure and convenient installation. The key technical points are: it includes a button cover and a button holder; the button holder has at least one slot in the middle; the inner wall of the button cover has a first locking block that matches the slot; and the inner wall of the button cover has at least one second locking block that abuts against the outer wall of the button holder. Through the cooperation of the first locking block and the slot, and the abutting of the second locking block against the outer wall of the button holder, the button cover is fixedly mounted on the button holder from multiple angles and directions, ensuring stability. Because the second locking block abuts against the outer wall of the button holder, the button holder does not obstruct the button cover during installation, allowing direct observation and facilitating installation…

[0004] The switches mentioned above are mainly for controlling lights. However, in actual use, some switches need to be installed in bathrooms and kitchens. Bathrooms and kitchens are inevitably in contact with water (especially bathrooms where there is a lot of moisture when showering), so water can easily enter the switch. Since impure water is a conductor, it can cause the switch to leak electricity. In this case, people who touch the switch may be at risk of contact hazards.

[0005] Furthermore, in the prior art, Chinese patent CN206697388U discloses a wall switch, including a base, a pressure cover disposed within the base, a face frame disposed on the base, a button rotatably disposed on the base, a switch button rotatably disposed within the pressure cover and linked with the button, a moving contact bridge linked with the switch button, a stationary contact, and a terminal block. The base has two symmetrically arranged mounting holes, and two support plates are disposed on one side of the base corresponding to the two mounting holes. The button is rotatably disposed on the two support plates, and the base has arc-shaped buffer holes separating the two support plates and the two mounting holes. This utility model has the advantages of simple structure, stable and reliable performance, and convenient assembly…

[0006] The switch described above is connected to the junction box installed inside the wall by a snap-fit ​​mechanism during installation. However, when it needs to be disassembled, tools are required to pry up the snap-fit ​​mechanism to complete the disassembly. In the process of prying with tools, the panel can be easily damaged, resulting in waste of materials. Summary of the Invention

[0007] The purpose of this invention is to provide a stable and reliable wall switch to solve the problems mentioned in the background art, such as the risk of electric shock due to water leakage and the waste caused by damage during panel disassembly.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a stable and reliable wall switch, comprising a switch box, a mounting plate, a control button, a luminous strip, a protective panel, an observation window, and an LED indicator light, and further comprising:

[0009] A switch box is embedded in a pre-drilled groove in the wall. The switch box has a hollow square structure and a protective net is horizontally fixed at the lower end of the interior of the switch box.

[0010] The mounting plate is fixedly installed on the outside of the front side of the switch box using screws. A control panel is fixedly installed in the middle of the front outer surface of the mounting plate, and a junction box is fixedly installed in the middle of the rear outer surface of the mounting plate. Switch contacts are fixedly installed on the front outer surface of the mounting plate, and an access wire for connecting to the household circuit is connected inside the junction box.

[0011] Control buttons are installed on the front side of the mounting plate. There are two control buttons arranged symmetrically on the left and right sides, and the control buttons are fixedly installed on the external mounting shaft on the front side of the control panel. constitute The control button is rotated and its position corresponds to the position of the switch contact.

[0012] A luminous strip is fixedly installed on the upper and lower ends of the outer surface of the control button;

[0013] A protective panel is installed on the front side of the mounting plate. The protective panel is used to protect the mounting plate and is made of insulating PVC material. A transparent observation window is fixedly installed at the middle of the upper end of the protective panel.

[0014] An LED indicator light is fixedly installed on the outer surface of the front side of the mounting plate. The LED indicator light emits red light when turned on, and the position of the LED indicator light corresponds to the position of the observation window.

[0015] The mounting clip is rotatably mounted on the outer front surface of the mounting plate, and the mounting clip is designed in a "7" shape.

[0016] A drying plate is installed inside the switch box. The drying plate is made of calcium oxide and is located below the protective net. The drying plate is connected to the inner wall of the switch box through a rotating shaft that is fixedly installed thereto.

[0017] A lower contact plate is fixedly installed at the lower end of the groove opened on the front surface of the control panel, and an upper contact plate fixedly installed on the control panel is provided directly above the lower contact plate. Both the upper and lower contact plates are made of copper conductive material.

[0018] Both the upper contact plate and the lower contact plate are made of conductive copper material, and a conductive device is fixedly connected between the upper contact plate and the lower contact plate. After the conductive material absorbs water, the conductivity of water makes the upper contact plate and the lower contact plate conductive.

[0019] The conductive device is configured as a cotton rope-like structure, and the upper contact plate is connected to the LED indicator light via a connecting wire that is fixedly installed thereto. constitute An electrical connection is established between the upper and lower contact plates. Once the connection is established, the LED indicator light illuminates via the connecting wires, thus serving as a reminder.

[0020] Preferably, a reset spring is fixedly installed between the side of the mounting buckle and the mounting plate, and a push button corresponding to the position of the mounting buckle is slidably installed through the upper and lower sides of the protective panel. The elasticity of the reset spring is used to squeeze the mounting buckle, thereby making the mounting buckle and the protective panel engage and install.

[0021] Preferably, a driven bevel gear is coaxially fixedly installed at the front end of the rotating shaft, and a driving bevel gear that is rotatably connected to the switch box is meshed on the side of the driven bevel gear. When the driving bevel gear rotates, it drives the rotating shaft to rotate by meshing with the driven bevel gear, thereby causing the rotating shaft to drive the drying plate to rotate.

[0022] Preferably, the drive bevel gear is connected to a transmission belt on its side, and the upper end of the transmission belt drives the transmission gear to rotate synchronously. When the transmission gear rotates, it drives the drive bevel gear to rotate through the transmission belt.

[0023] Preferably, a transversely distributed active rack is meshed above the transmission gear, and a connecting rod that forms a through-sliding structure with the mounting plate is fixedly installed on the side of the active rack. When the control button is pressed, the connecting rod slides inward, thereby driving the active rack fixedly installed thereto to move synchronously. When the active rack moves, it drives the transmission rack meshed with it to rotate.

[0024] Preferably, a sliding block is rotatably mounted on the top end of the connecting rod, and the sliding block engages with a sliding groove formed on the outer surface behind the control button. constituteThe sliding structure allows the sliding block at the top of the connecting rod to slide within the sliding groove during movement.

[0025] Compared with the prior art, the beneficial effects of this invention are as follows: This stable and reliable wall switch adopts a novel structural design, so that if water enters the internal device during use, the cotton conductive device absorbs the water and uses the water to conduct between the upper and lower contact plates, thereby further connecting the LED indicator circuit. The LED indicator then reminds personnel not to touch the switch temporarily to avoid the risk of electric shock. Furthermore, the drying plate inside the switch box dries the interior, further preventing moisture-induced electric shock. Moreover, the protective panel can be disassembled without using brute force, thus avoiding damage during disassembly. The specific details are as follows:

[0026] 1. The upper contact plate, lower contact plate, conductive device, and LED indicator work together. When water enters the switch, the cotton conductive device first absorbs the water. Under the conductivity of the water, the upper and lower contact plates are connected. At this time, the power supply to the LED indicator is connected by the connecting wire, causing the LED indicator to light up red. Personnel can see the light through the observation window, thus achieving the purpose of reminding people not to touch the switch temporarily to avoid the risk of electric shock.

[0027] 2. The drying plate, driving bevel gear, driven bevel gear, driving rack and connecting rod work together to dry the inside of the switch box and reduce moisture. When the control button is pressed, the connecting rod moves. At this time, the meshing action between the driving rack and the transmission gear drives the driving bevel gear to rotate, which in turn drives the driven bevel gear to rotate the rotating shaft. The rotating shaft drives the drying plate to rotate, which causes the drying plate to flip over so that it absorbs water evenly.

[0028] 3. The mounting clip, reset spring, and press button work together. The elasticity of the reset spring pushes the mounting clip to a vertical position, thus forming a locking structure with the protective panel. When it is necessary to remove the protective panel, simply press down on the press button to squeeze the mounting clip, causing it to disengage from the protective panel. This eliminates the need for brute force and avoids damage to the protective panel. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1-9This invention provides a technical solution: a stable and reliable wall switch, including a switch box 1, a mounting plate 2, control buttons 3, a luminous strip 5, a protective panel 6, an observation window 7, and an LED indicator 9. It further includes: the switch box 1, embedded in a pre-drilled groove in the wall, the switch box 1 having a hollow square structure, and a protective mesh 101 horizontally fixedly installed at the lower end of the interior of the switch box 1; the mounting plate 2, fixedly installed on the front exterior of the switch box 1 with screws, a control panel 201 fixedly installed at the center of the front outer surface of the mounting plate 2, and a junction box 202 fixedly installed at the center of the rear outer surface of the mounting plate 2, and switch contacts 8 fixedly installed on the front outer surface of the mounting plate 2, with an access wire 11 connected to a household circuit inside the junction box 202; and two control buttons 3, installed on the front of the mounting plate 2, symmetrically arranged on both sides, and the control buttons 3 are connected to a mounting shaft 4 fixedly installed on the front exterior of the control panel 201. constitute A rotating connection is provided, and the position of the control button 3 corresponds to the position of the switch contact 8. A luminous strip 5 is fixedly installed on the upper and lower ends of the outer surface of the control button 3. A protective panel 6 is installed on the front side of the mounting plate 2. The protective panel 6 is made of insulating PVC material, and a transparent observation window 7 is fixedly installed at the middle of the upper end of the protective panel 6. An LED indicator 9 is fixedly installed on the outer surface of the front side of the mounting plate 2. The LED indicator 9 emits red light when turned on, and the position of the LED indicator 9 corresponds to the position of the observation window 7. A drying plate 12 is installed inside the switch box 1. The drying plate 12 is made of calcium oxide material, and the drying plate 12 is located below the protective net 101. The drying plate 12 is connected to the inner wall of the switch box 1 through a rotating shaft 13 fixedly installed thereto.

[0041] A lower contact plate 14 is fixedly installed at the lower end of a groove opened on the front surface of the control panel 201, and an upper contact plate 15 is fixedly installed above the lower contact plate 14 and fixedly mounted to the control panel 201. Both the upper contact plate 15 and the lower contact plate 14 are made of conductive copper material, and a conductive device 16 is fixedly connected between the upper contact plate 15 and the lower contact plate 14. The conductive device 16 is set as a cotton rope-like structure, and the upper contact plate 15 is connected to the LED indicator 9 through a connecting wire 17 fixedly installed thereto. constituteElectrically connected, a driven bevel gear 20 is coaxially fixedly mounted on the front end of the rotating shaft 13, and a driving bevel gear 21 rotatably connected to the switch box 1 is meshed on the side of the driven bevel gear 20. A transmission belt 22 is connected to the side of the driving bevel gear 21, and the upper end of the transmission belt 22 drives the transmission gear 23 to rotate synchronously. A transversely distributed driving rack 24 is meshed above the transmission gear 23, and a connecting rod 25 forming a through sliding structure with the mounting plate 2 is fixedly mounted on the side of the driving rack 24. A sliding block 26 is rotatably mounted on the top of the connecting rod 25, and the sliding block 26 engages with a sliding groove 27 opened on the outer surface of the rear side of the control button 3. constitute Sliding structure;

[0042] When using the device, pressing the control button 3 activates the switch contact 8, thereby turning the light on or off. Pressing the control button 3 also causes the connecting rod 25 to extend and retract relative to the mounting plate 2. During this movement, the connecting rod 25 drives the active rack 24 to move synchronously. The active rack 24, in turn, drives the transmission gear 23, which meshes with it, to rotate. This rotation, via the transmission belt 22, drives the active bevel gear 21 to rotate. The driven bevel gear 20, meshing with the active bevel gear 21, then drives the rotating shaft 13 to rotate. This causes the rotating shaft 13 to flip the drying plate 12 (which uses calcium oxide to dry the inside of the switch box 1 during normal use). Flipping the plate allows for even water absorption, resulting in better drying.

[0043] When the device is in normal use, when water enters the surface of the mounting plate 2, the conductive device 16 made of cotton material absorbs the water. Then, the conductivity of water makes the upper contact plate 15 and the lower contact plate 14 conductive. At this time, the current flows through the lower contact plate 14 through the conductive device 16, then into the upper contact plate 15, and finally into the LED indicator 9 through the connecting wire 17 connected to the upper contact plate 15. At this time, the LED indicator 9 lights up, reminding personnel not to touch the switch temporarily to avoid the risk of electric shock.

[0044] The mounting buckle 10 is rotated and installed on the outer surface of the front side of the mounting plate 2. The mounting buckle 10 is set as a "7" shaped structure. A reset spring 18 is fixedly installed between the side of the mounting buckle 10 and the mounting plate 2. The upper and lower sides of the protective panel 6 are slidably installed with push buttons 19 corresponding to the positions of the mounting buckle 10.

[0045] After the LED indicator 9 is lit, disconnect the circuit of the switch, and then press the button 19 on the outside of the protection panel 6 from both the top and bottom sides at the same time. Press the button 19 to squeeze the mounting clip 10. When the mounting clip 10 is disengaged from the protection panel 6, the protection panel 6 can be quickly removed. Then dry the water stains on the mounting plate 2.
