Description

Technical Field

[0001] The utility model relates to a temperature sensitive controller, in particular to a temperature sensitive controller for electric tea set appliances. Background Art

[0002] Existing electric tea sets with anti-dry-burning or other functions mainly include: temperature-sensitive controllers, thermistors, electric heating elements, circuit boards, power supplies, etc. Since temperature-sensitive controllers are basic components, the complete machine manufacturer assembles connectors, such as connectors with steam holes and manual reset switches, as needed after purchase. Due to the large number of models, the assembly of components is very cumbersome and production efficiency is low. Because all components require various connectors, the entire temperature-sensitive controller actually occupies a large amount of space after assembly, which cannot meet the current demand for miniaturization. At the same time, the cumbersome post-assembly and the internal wiring are messy, which is not conducive to detection and maintenance. Furthermore, the manual switch of a typical temperature-sensitive controller is directly connected to the lever spring mechanism of the temperature-sensitive controller via a snap-on member. The manual reset switch of this structure has a small stroke and is prone to misoperation, seriously affecting the safety and life of the product. Summary of the Invention

[0003] The purpose of the utility model is to provide a temperature sensitive controller which has a simple structure, is safe and stable, and is conducive to small-scale integration in order to address the defects of the existing technology.

[0004] To achieve the above-mentioned object, the present invention adopts the following technical solution: a temperature-sensitive controller, comprising a main housing, a fixing plate fixedly mounted on the main housing, a lever-spring mechanism mounted on the front face of the main housing in a swinging linkage, a heating switch device mounted on the head of the main housing and controlled to open and close by the lever-spring mechanism, a switch frame with a protruding switch, the rear end of the main housing having a support shaft integrally formed with the main housing, and the switch frame being rotatably connected to the main housing via the support shaft.

[0005] As an improvement: the switch frame includes a connector connected to the lever spring mechanism, a switch body with a protruding switch at the tail, the front end of the switch body is connected to the connector or integrally formed, and the middle part of the switch body is rotatably connected to the support shaft, so that the switch frame forms a seesaw structure on the main housing.

[0006] As an improvement: the connecting body of the switch frame is generally U-shaped, that is, the connecting body has two rocker arms that cooperate with the lever spring mechanism. The exposed switch of the switch body is manually operated. The switch frame pries the connecting body with the support shaft as the fulcrum, and the two rocker arms of the connecting body drive the lever spring mechanism to swing and link, thereby realizing manual opening and closing of the heating switch device.

[0007] As an improvement: a boiling bimetallic actuator capable of activating a lever spring mechanism is fixedly mounted on the rear back of the main housing.

[0008] As an improvement: the support shaft is located at the rear end of the main housing and is far away from and spaced from the boiling bimetallic actuator.

[0009] As an improvement: the tail end of the main shell where the support shaft is located is separated from the boiling bimetallic actuator by a partition wall integrally formed with the main shell, that is, the tail end of the main shell protrudes from the outer wall of the partition wall to form a support body, and extends to the left and right ends of the support body to form a support shaft that cooperates with the switch frame.

[0010] This new temperature-sensitive controller connects the switch frame to the main housing via a pivot integrally formed with the main housing. This inherent pivot eliminates the need for the manufacturer to provide a separate connector, thus avoiding external mismatches. This not only saves space but also facilitates assembly and production, saving time and effort. Furthermore, compared to existing designs that require separate connectors, the new design with its own pivot offers greater stability, allowing for more precise positioning of the U-shaped switch frame on the main housing, significantly extending the life of the entire manual switch.

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, a specific embodiment of the temperature-sensitive controller of the present invention comprises a main housing 1, a fixing plate 2 fixedly mounted on the main housing 1, a boiling bimetallic actuator 4 fixedly mounted on the rear back of the main housing, a lever-spring mechanism 3 mounted on the front of the main housing 1 and actuated by the boiling bimetallic actuator 4 to swing the main housing in a coordinated manner, a heating switch device 5 mounted on the head of the main housing and controlled by the lever-spring mechanism 3 to open and close, and an externally connected switch frame 6 with a protruding switch 64. The rear of the main housing is provided with a support shaft 11 integrally formed with the main housing, and the switch frame 6 is rotatably connected to the main housing 1 via the support shaft 11. In this embodiment, the externally connected switch frame 6 comprises a connector 61 connected to the lever-spring mechanism 3 and a switch body 62 with a protruding switch at the rear end. In this embodiment, the front end of the switch body 62 is connected to the connector 61, but it can also be integrally formed. The assembler can configure the switch frame 6 according to the actual needs of the entire device. Simply by rotatably connecting the middle portion of the switch body 62 to the support shaft 11, the switch frame 6 forms a seesaw structure on the main housing. The connector 61 of the switch frame 6 is generally U-shaped, with two rocker arms 63 engaging the lever-spring mechanism 3. To manually operate the protruding switch of the switch body 62, the switch frame pries the connector 61 with the support shaft 11 as a fulcrum. The two rocker arms 63 of the connector drive the lever-spring mechanism 3 to swing in a coordinated manner, thereby manually opening and closing the heating switch device 5. In this embodiment, the support shaft 11 is located at the rear end of the main housing, spaced apart from and away from the boiling bimetallic actuator 4. The rear-end position of the support shaft allows for greater travel of the end of the U-shaped switch frame's operating arm, and the external button connected to the U-shaped switch frame is closer to the support shaft, providing a certain degree of damping to prevent accidental activation.

[0017] To ensure the stability and durability of the fulcrum, this embodiment separates the rear end of the main housing where the fulcrum 11 resides from the boiling bimetallic actuator 4 by a partition wall 13 integrally formed with the main housing. Specifically, the rear end of the main housing projects outward from the outer wall of the partition wall 13 to form a support body 14. From this support body, the left and right ends extend to form the fulcrum 11, which mates with the switch frame 6. The support bodies 14 further enhance the stability of the fulcrum support. This resolves the existing problem where the fulcrums are located on the left and right sides of the main housing, supporting the switch frame and hindering the main housing's connection to the boiling bimetallic actuator 4.

[0018] The utility model has a very high integration for the whole machine, occupies a very small volume, has a neat and clear interior, and has exquisite details, which is convenient for later maintenance and repair.

[0019] Although the present invention has been disclosed above with reference to specific embodiments, they are not intended to limit the present invention. Any person skilled in the art may make slight changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of the appended claims.
