Description

Technical Field

[0001] This utility model relates to the field of electrical control equipment technology, specifically a light regulator with an anti-accidental touch structure. Background Technology

[0002] Lighting dimmers, as common electrical control devices, are widely used in various lighting systems in homes, offices, and commercial spaces. Their core function is to adjust the brightness of lights by changing the voltage or current in the circuit to meet the lighting needs of different scenarios. Currently, most lighting dimmers on the market adopt knob, button, or touch-sensitive structures. Knob dimmers are widely used due to their intuitive operation and high adjustment precision. Their basic structure typically includes an adjustment knob, internal adjustment components, and a housing. Users rotate the knob to actuate the internal components, thereby changing the light brightness.

[0003] Existing light regulators, due to the direct exposure of the touch control parts to the outside and the lack of effective limiting or locking structures, may cause accidental touches by human limbs, clothing, or other objects during daily use, resulting in unintended adjustments to the light brightness and affecting the lighting effect. Furthermore, the lack of corresponding anti-accidental touch or shielding structures for the buttons or touch areas makes them prone to misoperation due to slight touches. Utility Model Content

[0004] The purpose of this utility model is to provide a light regulator with an anti-accidental touch structure to solve the problems mentioned in the background art, where the touch part of the structure is directly exposed to the outside, lacks an effective limiting or locking structure, and the knob is easily touched, resulting in the light brightness being accidentally adjusted, affecting the lighting effect. In addition, the lack of corresponding anti-accidental touch or shielding structures for the buttons or touch areas makes it easy to cause misoperation due to slight touch.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a light regulator with an anti-accidental touch structure, including a mounting base, which is the main support structure of the light regulator, wherein the upper end of the mounting base is engaged with the outer shell body, and the mounting base and the outer shell body together form an accommodating space;

[0006] A wiring circuit board is mounted on the upper end of the mounting base, and the wiring circuit board is connected to the terminal block group via a cable. The wiring circuit board is electrically connected to the microprocessor and the power management circuit, and the microprocessor is electrically connected to the control button.

[0007] The upper end of the outer casing has a groove near the edge, and a wiring terminal group is placed in the groove of the outer casing. A protective limit seat is provided at the upper end of the outer casing, and the shaft of the control knob passes through the protective limit seat.

[0008] By adopting the above technical solution, the mounting base and the main body of the outer shell are engaged to form a receiving space, which houses the wiring circuit board and other components. In addition, the protective limit seat and the control knob reduce the exposure of adjustment components, reduce the probability of accidental adjustment of light brightness due to accidental touch, and ensure stable lighting effect.

[0009] Preferably, the mounting base is arranged perpendicular to the outer shell body, and both the mounting base and the outer shell body are provided with mounting holes.

[0010] By adopting the above technical solution, the mounting base is vertically placed with the main body of the outer shell and is provided with mounting holes, which enhances the overall structural stability, provides a stable environment for the internal components, and indirectly ensures the reliable operation of the anti-accidental touch structure and adjustment function.

[0011] Preferably, the outer casing body is provided with a mounting hole for the control knob to pass through, and the edge of the mounting hole is provided with an annular protrusion, which abuts against the bottom of the protective limiting seat.

[0012] By adopting the above technical solution, the annular protrusion abuts against the bottom of the protective limit seat, which improves the installation stability of the protective limit seat, making it more effective in protecting the control knob and enhancing the anti-accidental touch effect.

[0013] Preferably, the wiring circuit board connects the terminal block and the microprocessor, and the microprocessor is connected to the power management circuit.

[0014] By adopting the above technical solution, the wiring circuit board connects all components, ensuring stable transmission of electrical signals, enabling the microprocessor to accurately receive and process instructions, ensuring the normal implementation of the adjustment function, and reducing the impact of misoperation caused by signal problems.

[0015] Preferably, the control button has a raised structure, the height of the control button is higher than the outer surface of the housing body, and the surface of the control button is provided with anti-slip protrusions.

[0016] The above technical solution, with its raised control button design and anti-slip protrusions, facilitates precise operation by users, reduces the probability of accidental presses, and avoids accidental unlocking and subsequent adjustment errors caused by accidental button touches.

[0017] Preferably, there is a limit spring between the shaft of the control knob and the knob head, and there is a protective limit seat on the outside of the shaft of the control knob.

[0018] Using the above technical solution, the limit spring locks the control knob in its normal state, allowing it to rotate only after unlocking, thus forming a mechanical limit.

[0019] Preferably, a gap is left between the outer wall surface of the control knob head and the inner wall of the protective limit seat.

[0020] The above technical solution, with its gap design between the control knob and the protective limit seat, ensures that normal adjustment operation is not affected, while also effectively preventing external contact with the protective limit seat.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the light regulator with an anti-accidental touch structure:

[0022] 1. A protective limit seat is fitted onto the outside of the control knob's shaft, with a gap between the outer wall of the control knob's head and the inner wall of the protective limit seat. This design does not affect normal operation and provides a surrounding protection for the control knob, preventing accidental contact from the outside. At the same time, the edge of the mounting hole on the outer shell through which the control knob passes has an annular protrusion that abuts against the bottom of the protective limit seat, enhancing the installation stability of the protective limit seat and further improving the protection effect on the control knob, preventing accidental adjustment of the light brightness due to contact.

[0023] 2. The limiting spring between the control knob's shaft and head, along with the locking mechanism linked to the control button, provides effective limiting and locking functions for the adjustment components. Pressing the control knob separates the knob head and shaft, forming a limiting engagement with the protective limit seat and locking the knob to prevent accidental rotation during non-operation. Only when the user presses the control knob to close the knob head and shaft can the user rotate the control knob for adjustment, avoiding misoperation due to the lack of a locking structure and ensuring the stability of the light brightness.

[0024] 3. The control buttons adopt a raised design with anti-slip protrusions on the surface, which makes it easy for users to accurately identify and operate them, reducing the possibility of accidental pressing. The terminal block is placed in a groove on the upper part of the housing near the edge, which not only facilitates wiring connection, but also prevents the terminal block from being accidentally touched due to exposure, ensuring the electrical connection stability of the equipment and further guaranteeing the normal operation of the lighting system.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-6 This utility model provides a technical solution: a light regulator with an anti-accidental touch structure, including a mounting base 1, a housing body 2, a wiring circuit board 3, a wiring terminal group 4, a microprocessor 5, a control button 6, a power management circuit 7, a protective limit seat 8, a control knob 9, and a limit spring 10.

[0034] Among them, the mounting base 1 is the main support structure of the light regulator. The upper end of the mounting base 1 is connected to the outer shell 2, and the mounting base 1 and the outer shell 2 together form a receiving space.

[0035] A wiring circuit board 3 is mounted on the upper end of the mounting base 1, and the wiring circuit board 3 is connected to the terminal block 4 via a cable. The wiring circuit board 3 connects the terminal block 4 and the microprocessor 5, and the microprocessor 5 is connected to the power management circuit 7. The mounting base 1 is vertically positioned to the housing body 2, and both the mounting base 1 and the housing body 2 are provided with mounting holes. The housing body 2 is provided with mounting holes for the control knob 9 to pass through, and the edge of the mounting hole is provided with an annular protrusion. The annular protrusion abuts against the bottom of the protective limit seat 8. The wiring circuit board 3 is electrically connected to the microprocessor 5 and the power management circuit 7, and the microprocessor 5 is electrically connected to the control button 6. The control button 6 adopts a raised structure, and the height of the control button 6 is higher than the outer surface of the housing body 2. The surface of the control button 6 is provided with anti-slip protrusions.

[0036] Referring to the attached diagrams in the instruction manual Figures 1-6As shown, fix the mounting base 1 in the preset installation position to ensure its stability. Then, install the wiring circuit board 3 on the upper end of the mounting base 1, and connect the wiring circuit board 3 to the terminal block 4 through the cable. Subsequently, connect the microprocessor 5 and the power management circuit 7 to the wiring circuit board 3, and connect the control button 6 to the microprocessor 5.

[0037] Next, place the terminal block 4 into the groove near the edge of the upper part of the housing body 2, and then install the protective limit seat 8 on the upper part of the housing body 2, so that the shaft of the control knob 9 passes through the protective limit seat 8. At the same time, ensure that the limit spring 10 between the shaft of the control knob 9 and the knob head is installed in place. Then, snap the housing body 2 onto the upper part of the mounting base 1 so that the mounting base 1 and the housing body 2 together form a receiving space to complete the overall installation. After the installation is completed, connect the external power supply line and the lighting load line to the terminal block 4. The power management circuit 7 will process the power into a stable power supply to power the microprocessor 5 and other components.

[0038] The upper end of the outer shell 2 has a groove near the edge, and the wiring terminal group 4 is placed in the groove of the outer shell 2. The upper end of the outer shell 2 is provided with a protective limit seat 8, and the shaft of the control knob 9 passes through the protective limit seat 8. There is a limit spring 10 between the shaft of the control knob 9 and the knob head, and there is a protective limit seat 8 on the outside of the shaft of the control knob 9. There is a gap between the outer wall of the knob head of the control knob 9 and the inner wall of the protective limit seat 8.

[0039] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, when it is necessary to adjust the brightness of the light, the user first finds the control button 6 on the main body 2 of the outer shell and presses it. The control button 6 sends an unlock signal to the microprocessor 5, and the microprocessor 5 then instructs to unlock the anti-accidental touch lock.

[0040] After unlocking, the user presses down on the knob head of control knob 9 to connect the knob head to the shaft, and then rotates control knob 9. Because there is a gap between the knob head and the inner wall of the protective limit seat 8, and the protective limit seat 8 is fixed by the annular protrusion of the outer shell 2, the rotation process is smooth and not affected by external accidental touches. The rotation of control knob 9 is transmitted to the adjustment component of the wiring circuit board 3 via the shaft. This component converts the mechanical rotation into an electrical signal and transmits it to the microprocessor 5. After receiving the signal, the microprocessor 5 calculates the corresponding brightness adjustment parameters, and then sends a control signal to the lighting load through the wiring circuit board 3 and the wiring terminal group 4. The brightness of the light changes accordingly. After the user adjusts the knob to the appropriate brightness according to their needs, they release control button 6 and simultaneously release the knob head of control knob 9. The limit spring 10 returns to its original state, so that control knob 9 returns to the locked state, preventing subsequent accidental touches that could cause brightness changes.

[0041] Working principle: When using this light regulator with an anti-accidental touch structure, the mounting structure is provided by the electrical components installed between the mounting base 1 and the housing body 2. The terminal block 4 is connected to the wiring circuit board 3 through the cable. After the external power supply line and the light load line are connected to the terminal block 4, the power management circuit 7 processes the electrical energy into a stable power supply to power the microprocessor 5 and other components.

[0042] When adjusting the light brightness, the user first locates and presses the control button 6 on the main body 2. This sends an unlock signal to the microprocessor 5, which then instructs the anti-accidental touch lock to be released. After unlocking, the user can press down on the knob head of the control knob 9, connecting the knob head to the shaft. The knob head then rotates, and the rotation is transmitted to the adjustment component of the wiring circuit board 3 via the shaft. This component converts the mechanical rotation into an electrical signal and transmits it to the microprocessor 5. Because there is a gap between the knob head and the inner wall of the protective limit seat 8, and the protective limit seat 8 is fixed by the annular protrusion of the main body 2, the rotation process is smooth and not affected by external accidental touches. After receiving the signal, the microprocessor 5 calculates the corresponding brightness adjustment parameters and then sends a control signal to the light load through the wiring circuit board 3 and the terminal block 4. The light brightness changes accordingly. After adjusting the knob to the appropriate brightness as needed, the user releases the control button 6. At this time, the knob head of the control knob 9 is released, allowing the limit spring 10 to return to its original position, preventing subsequent accidental touches from causing brightness changes.

[0043] Throughout the process, the protective limit seat 8 always surrounds the control knob 9 for protection. Combined with the locking mechanism, this ensures both the convenience of adjustment and the effective prevention of accidental touches, ensuring stable light brightness and increasing overall practicality.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
