[0030] The following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings, so that those skilled in the art can better understand and implement the present invention.

[0031] The present invention discloses a rotary multi - gear speed regulation switch. As Figures 1 to 7As shown, the multi - gear speed - regulating switch 1 of the present utility model mainly includes a decorative panel 2, a gear - shifting module 3 coupled to the central part of the panel 2 in a snap - fit form, a knob 4 connected to the gear - shifting module 3, and a speed - regulating circuit module 5. The gear - shifting module 3 is a set of mechanical multi - gear wire dividers, responsible for switching between three electrical gears and one neutral gear. Users can select between different gears through the knob 4. The knob 4 is designed with ergonomics in mind, being easy to hold and rotate, and the rotation of the knob 4 can actuated the gear - shifting module 3 and the speed - regulating circuit module 5 external to the gear - shifting module 3, realizing the adjustment of the ceiling fan switch and speed. The gear - shifting module 3 adopts a modular design, integrating multiple mechanical and conductive components, and is housed in a sealed housing, protecting each mechanical and conductive component from external obstacles and influences on its operation, while extending the life of the mechanical multi - gear wire divider. At the bottom of the gear - shifting module 3, there are multiple electrical connection terminals 31, including a main electrical connection terminal 32 and multiple gear electrical connection terminals 33. The main connection terminal 32 is located at the central position, surrounded by three gear connection terminals 33, as Figure 3 shown. The above - mentioned multiple gears also include a neutral gear for cutting off the power supply. Each electrical connection terminal 31 is provided with a fixing screw 310 for inserting and fixing the wire to prevent loosening. The housing 34 fixedly supports the electrical connection terminals 31 and correspondingly provides an opening 35 for a screwdriver to tighten the fixing screw 310. The housing 34 is composed of an upper housing part 34a and a lower housing part 34b. The upper housing part 34a is provided to provide rotational support for the gear - shifting shaft 36, and the lower housing part 34b is provided to fixedly support the multiple electrical connection terminals 31.

[0032] The knob 4 is installed on the top of the gear - shifting module 3. The knob 4 is connected to the mechanical components of the gear - shifting module 3, so that the knob 4 can directly rotate the gear - shifting shaft 36 inside the gear - shifting module 3 to achieve rotational gear - shifting. The knob 4 is designed in a conical shape or other ergonomic shapes for easy holding and rotation. By rotating the knob 4, the mechanism inside the gear - shifting module 3 can be actuated to realize the switching and speed adjustment of the ceiling fan. Users can select between four gears through the knob 4. The 0 - gear is in the off state, and the 1 - to 3 - gears are different operating speeds of the ceiling fan. The gear - shifting module 3 is set at the central position of the panel 2, and there are mounting points for fixing on the wall on the back of the panel 2.

[0033] The gear shifting module 3 includes a gear shifting shaft 36 and a plurality of electrical connection terminals 31 corresponding to different gears. The electrical connection terminal 31 includes a main electrical connection terminal 32 and a plurality of gear electrical connection terminals 33. The gear shifting shaft 36 is rotatably supported by the housing 34 of the gear shifting module 3. By rotating, the gear shifting shaft 36 can selectively connect the main electrical connection terminal 32 with one of the gear electrical connection terminals 33. An electrical connection element 39 is provided on the gear shifting shaft 36, and the electrical connection element 39 is always movably connected to the main electrical connection terminal 32. When the gear shifting shaft 36 rotates to a non-neutral gear, the electrical connection element 39 contacts the corresponding gear electrical connection terminal 33.

[0034] In some embodiments, each electrical connection terminal 31 is provided with a contact portion 38 to assist the electrical connection element 39 in making a transition, so as to help the electrical connection element 39 make smooth contact and transition. The gear shifting shaft 36 has a rotating shaft 41 and a turntable 42 connected to the knob 4. A groove 43 for fixing and accommodating the electrical connection element 39 is provided on the turntable 42. Preferably, a through hole 44 penetrating the turntable 42 is provided in the groove 43 for accommodating the spring plunger 50. One end of the spring plunger 50 presses on the electrical connection element 39, applying a downward biasing force to the electrical connection element 39, so that the electrical connection element 39 is stably pressed on the contact portion 38 of the electrical connection terminal 31. In some embodiments, one end of the electrical connection element 39 is a convex curved surface 45 facing the direction of the electrical connection terminal 31, and a concave portion 46 is provided at the position where the other end contacts the main electrical connection terminal 37, making the connection with the main electrical connection terminal 32 more stable. This design ensures the smooth transition and reliable connection of the electrical connection element 31 between different gears, improving the overall performance and service life of the speed control switch 1. Further, the other end of the spring plunger 50 is provided with a wedge-shaped tip 51, and its design is adapted to cooperate with the concave and convex portions 52 at the corresponding position in the upper housing 34a. When the gear shifting shaft 36 rotates to different gears, the tip of the spring plunger 50 will interact and engage with the convex and concave portions 52 in the upper housing 34a. This design not only provides stable positioning, but also can generate clear feedback through mechanical contact, enabling the user to feel a distinct "click" sensation when adjusting the gear, so as to ensure that the user can accurately adjust to the desired gear. This stable positioning mechanism and clear feedback greatly improve the user experience of the speed control switch 1 and avoid misoperation caused by hand tremors or other external vibrations. Through this design, not only the accuracy of gear adjustment is guaranteed, but also the safety and stability of use are increased, enabling the speed control switch 1 to maintain good performance in various use environments.

[0035] The speed control switch 1 further includes a speed control circuit module 5, and the speed control circuit module 5 is arranged to be external to the gear shifting module 3. The speed control circuit module 5 is detachably connected to the plurality of electrical connection terminals 31 in a wiring form, as shown in Figure 7。The conversion module 3 is connected to the external speed control circuit module 5 through its electrical connection terminals 31 and wires 63, 64, 65. In this way, the speed control circuit module 5 is suspended by the wires, so that the speed control circuit module 5 does not need to be fixed to any part of the speed control switch 1. This design greatly simplifies the structure of the speed control switch 1. Since the speed control circuit module 5 is external, the installation of the speed control switch 1 is more flexible.

[0036] The design of the external speed control circuit module 5 can significantly save the space required in the wall, avoiding the installation difficulties and maintenance inconveniences caused by the close stacking of components in traditional speed control switches. This design not only makes the overall structure of the speed control switch 1 more compact, but also makes it convenient for users to simply disassemble and reconnect the external circuit module when maintenance or replacement of the circuit module is needed, with simple, fast and convenient operation. In addition, the external speed control circuit module 5 also improves the heat dissipation performance. Since the module is external, it can better contact with the external air, promoting the dissipation of heat, thereby extending the service life of electronic components and improving the reliability of the speed control switch. The modular design makes the speed control switch more adaptable in different application environments. Whether it is for home use or commercial places, the external circuit module can be flexibly adjusted according to needs to meet personalized speed control requirements.

[0037] The external speed control circuit module 5, as a key part of the speed control switch of the present utility model, is designed considering the requirements of structural simplification and installation convenience. In some embodiments, the speed control circuit module 5 is an integrated circuit variable frequency speed controller. The speed control circuit module 5 is composed of a small speed control circuit board 61 (PCB) and several wires 62. Electronic components for speed control and ports for welding wires are welded on the circuit board 61. Figure 6A and 6B As can be seen, the wires are respectively used for different electrical connection functions. For example, wires 63, 64, 65 are used for the transmission of electrical signals of different gears. The speed control circuit board 61 is provided with a plurality of connection terminals corresponding to different gears, and each connection terminal can be connected to the corresponding electrical connection terminal 31 through a wire. The speed control circuit board 61 is also provided with a connection terminal (not shown) for connecting to the ceiling fan motor. The detachable setting and arrangement of the wires and the electrical connection terminals 31 enable quick connection and disconnection, improving the efficiency of installation and maintenance. Advantageously, the circuit board 61 can be wrapped with insulating plastic, such as heat shrinkable rubber, to prevent accidental short circuits and provide protection.

[0038] The design of this external form is connected to the gear shifting module 3 through the electrical connection terminal 31, achieving precise speed control of the ceiling fan. The electrical connection terminal 31 adopts a wiring form, which means that users can easily connect the external speed control circuit module 5 to the gear shifting module 3 and can also easily disassemble and reconnect it when maintenance or replacement is required. The design of the external speed control circuit module 5 greatly simplifies the internal structure of the speed control switch 1, making the entire device more compact and effectively saving space inside the wall. The external speed control circuit module 5 not only provides flexibility in installation. The modular design concept also enables the speed control switch to adapt to different installation environments and requirements. Whether in a home or commercial venue, personalized speed control requirements can be achieved by simply adjusting the external circuit module. This design not only optimizes the functionality of the product but also enhances the user experience, providing a more convenient, efficient, and reliable solution.

[0039] Generally speaking, this design not only simplifies the internal wiring and component configuration but also improves the product's maintenance and upgrade capabilities. When the speed control circuit module needs to be repaired or replaced, users only need to disassemble and reconnect the external circuit module, which is simple and convenient to operate. At the same time, the design of the external speed control circuit module makes the use of space inside the wall more efficient, avoiding the installation difficulties caused by internal space limitations in traditional designs. More importantly, this modular design allows the speed control switch to have greater adaptability in different application environments. Whether in a home or commercial venue, personalized requirements can be achieved by adjusting the external circuit module.

[0040] Through the above design, the speed control switch of the present utility model simplifies the installation process, reduces the volume and cost, and at the same time improves the stability and safety of the product. Although the present utility model has been disclosed in a relatively specific implementation manner, it should be understood that these are only examples and are not used to limit the scope of the present utility model. For those skilled in the art, various changes and improvements can be made without departing from the spirit and scope of the present utility model, and these changes and improvements should all fall within the protection scope of the present utility model.
