Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical connection equipment, in particular to a rotary switch with a novel structure. BACKGROUND

[0002] In the rotary switch, the rotary switch is a common electrical element and is widely used in modern household appliances and industrial equipment, mainly for controlling the on-off and power regulation of the circuit. With the rapid development and technological progress of the household appliance industry, higher requirements are placed on the functionality and reliability of the rotary switch, especially in terms of reducing manufacturing costs and improving assembly efficiency.

[0003] Currently, in order to realize the connection of the rotary switch with external loads and power supplies, two main methods are commonly used: one is the plug-in connection method by directly inserting the power line into the conductive sheet; the other is to use terminals to be welded to the connector and then cooperate with the circuit board to complete the connection. The former is simple to operate but has poor stability, and the latter can support automated operation but significantly increases the overall cost due to the introduction of additional components. In addition, some designs rely on complex circuit board structures to integrate various functional modules, which further increases the cost of the product. The above-mentioned existing technologies all have some common problems, and they cannot simultaneously meet the requirements of low cost and compatibility with automated assembly. CONTENT OF THE INVENTION

[0004] In order to reduce the manufacturing cost of the rotary switch and enable it to be matched with household appliance automation assembly to improve production efficiency, the present application provides a rotary switch with a novel structure.

[0005] The present application provides a rotary switch with a novel structure, which adopts the following technical solution:

[0006] A rotary switch with a novel structure includes a housing, an adjustment assembly, and a first input assembly, a second input assembly, a first output assembly, and a second output assembly installed in the housing;

[0007] The adjustment assembly is installed on the housing and located at one end inside the housing;

[0008] The first input assembly is connected to the first output assembly;

[0009] One end of the second input assembly is connected to the adjustment assembly;

[0010] One end of the second output assembly is connected to the adjustment assembly;

[0011] One end of the first input assembly and the second input assembly is respectively connected to the power supply, and one end of the first output assembly and the second output assembly is respectively connected to the load.

[0012] By adopting the technical scheme, the traditional circuit board design is cancelled, and the first input assembly, the second input assembly, the first output assembly and the second output assembly are used to realize the construction of the electrical circuit, which effectively reduces the production cost and simplifies the overall structure. Among them, the first input assembly and the first output assembly directly form a stable current path and are connected with the load and the power supply, and the second input assembly and the second output assembly realize the switching between different power circuits by the action of the adjusting assembly, and then accurately control the working state of the load and the output power size. The connection between the rotary switch and the load and the power supply is simplified in the design scheme, which not only enhances the stability of the connection, but also makes the whole device suitable for automatic assembly process, greatly improves the production efficiency, and effectively reduces the problem of defective products caused by manual operation.

[0013] Preferably, the first input assembly and the first output assembly respectively have a bending part which is fitted with the inner wall of the shell, and the first input assembly and the first output assembly respectively have a straight part, the straight part of the first input assembly is connected with the power supply, and the first output assembly is connected with the load.

[0014] By adopting the technical scheme, the first input assembly and the first output assembly are respectively provided with a bending part and a straight part, so that they can be stably fixed inside the shell, and at the same time realize reliable connection with the power supply and the load. Specifically, the bending part is fitted with the inner wall of the shell, which enhances the structural stability and avoids position deviation caused by vibration or external force; the design of the straight part facilitates connection with external lines, simplifies the assembly process and improves the connection reliability. This design not only optimizes the space layout, but also effectively improves the overall performance and service life of the rotary switch.

[0016] By adopting the technical scheme, the space layout of the second input assembly and the second output assembly is optimized. Specifically, the design of the downward bending part enables the second input assembly and the second output assembly to closely fit with the positioning part of the shell, thereby improving the stability of the structure and avoiding position deviation caused by vibration or other external factors. At the same time, the above design ensures that the straight part of the second input assembly can be reliably connected with the power supply, and the straight part of the second output assembly can be stably connected with the load, further enhancing the reliability of the electrical connection.

[0018] By adopting the above technical scheme, the internal structure of the rotary switch is optimized. Specifically, the adjusting assembly is composed of an adjusting component and a switching component. One end of the adjusting component is located in the shell, and the other end is arranged in the shell, which is convenient for manual operation of the user while ensuring the stability of the internal structure. The switching component is installed on the adjusting component and is in contact with the second input assembly, so that the rotary switch can be flexibly switched between different loops, thereby realizing effective control of the output power of the load. The above structure not only simplifies the design of the traditional circuit board and reduces the manufacturing cost, but also improves the functionality and reliability of the rotary switch.

[0019] Preferably, the adjusting assembly has a resistance part.

[0020] By adopting the above technical scheme, the adjusting assembly is provided with a resistance part, which can provide appropriate damping feeling during the adjustment of the rotary switch. The problem of excessive rotation caused by excessive operating force is effectively avoided, and the operation accuracy and stability of the rotary switch during power switching are improved. At the same time, the existence of the resistance part can also improve the operation experience of the user, making each switching more clear and reliable.

[0021] Preferably, a locking part is arranged on the adjusting component, the locking part is in contact with the inner surface of the shell, a limiting part is arranged in the shell, and the locking part is clamped with the limiting part.

[0022] By adopting the above technical scheme, the locking part is in contact with the inner surface of the shell and clamped with the limiting part, which can effectively prevent the adjusting component from rotating or moving unexpectedly during work, and improve the overall stability of the rotary switch. This design ensures the accurate positioning of the adjusting assembly during operation, avoids functional abnormalities caused by external vibration or other interference factors, thereby improving the reliability and service life of the product.

[0023] Preferably, a spring part is arranged on the adjusting component, the spring part is embedded in the adjusting component, and one end of the spring part is in abutment with the switching component.

[0024] By adopting the above technical scheme, the spring part is embedded in the adjusting component and abuts with the switching component, which can provide stable elastic support when the adjusting component drives the switching component to switch the loop. This design effectively avoids the position deviation of the switching component during switching due to external vibration or improper operation, ensures the stable switching of the rotary switch between different power loops, and improves the reliability and service life of the product. At the same time, the arrangement of the spring part can also enhance the operation feeling, so that the user can obtain clear feedback when adjusting the power, and improve the user experience.

[0025] Preferably, the shell has a guide portion, at least one set of guide portions is arranged at the straight portion of the first input assembly and the first output assembly, and at least one set of guide portions is arranged at the straight portion of the second input assembly and the second output assembly.

[0026] By adopting the technical scheme, the shell structure is optimized. Specifically, the guide portion is added to facilitate the connection of the first input assembly, the second input assembly, the first output assembly and the second output assembly with external lines, simplify the assembly process, improve the connection reliability, and avoid the functional failure or damage caused by the position deviation when the external lines are inserted.

[0027] In summary, the present application has at least one of the following beneficial technical effects:
