Description

Technical Field

[0001] This utility model relates to the field of thermometers, and in particular to a compact temperature switch. Background Technology

[0002] A temperature switch is a type of temperature switch that uses a bimetallic strip as a temperature sensing element. When the appliance is working normally, the bimetallic strip is in a free state and the contacts are in a closed / open state. When the temperature rises to the operating temperature value, the bimetallic element generates internal stress due to heat and acts quickly, opening / closing the contacts, cutting off / connecting the circuit, thereby playing a thermal protection role. When the temperature drops to the reset temperature, the contacts automatically close / open, restoring the normal working state.

[0003] Currently, copper is the conventional material used for heat transfer, which relies on copper's physical thermal conductivity. However, this results in excessively high costs. In addition, the thermometers have slow response times, and the accuracy of the measurements needs improvement. Utility Model Content

[0004] The purpose of this invention is to provide a compact temperature switch to solve the problems mentioned in the background art.

[0005] The technical problem solved by this utility model is achieved through the following technical solution:

[0006] A compact temperature switch includes a Hirschmann connector, with one end of a protective tube fixedly connected to the lower end of the Hirschmann connector, and the other end of the protective tube connected to a circular detection end. The circular detection end is circular in shape, and a temperature switch core is provided in the inner cavity of the circular detection end. The temperature switch core is connected to the Hirschmann connector via a wire.

[0007] Preferably, the protective tube is provided with a process connection thread, which can be connected to the device to be tested.

[0008] Preferably, the protective tube can be made of stainless steel, which can greatly reduce costs while ensuring the temperature measurement effect.

[0009] The advantages and positive effects of this utility model are:

[0010] 1. This utility model uses a circular detection end with a circular structure and a temperature switch core to allow more heat to come into contact with the outer wall of the circular detection end for heat exchange, and more heat to enter the inner cavity of the circular detection end and come into contact with the temperature switch core. At this time, due to the increased heating area, the response speed is faster and the measurement value is more accurate.

[0011] 2. The protective tube of this utility model is made of stainless steel, which increases service life and reduces costs while ensuring the detection effect. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] The following is combined Figure 1-2 This utility model will be described in detail below. For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1 The directions of front, back, left, right, up, and down in the view are consistent. Figure 1 This is a front view of the device of this utility model. Figure 1 The directions shown are consistent with the front-facing, back-facing, left-right, up-down directions of the device.

[0018] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0019] Please see Figure 1-2 One embodiment of this utility model is a compact temperature switch, including a Hirschmann connector 10. The lower end of the Hirschmann connector 10 is fixedly connected to one end of a protective tube 11, and the other end of the protective tube 11 is connected to a circular detection end 14. The circular detection end 14 is circular, and a temperature switch core 15 is provided in the inner cavity of the circular detection end 14. The temperature switch core 15 is connected to the Hirschmann connector 10 through a wire.

[0020] In another embodiment, the protective tube 11 is provided with a process connection thread 13, which can be connected to the device to be tested.

[0021] In another embodiment, the protective tube 11 can be made of stainless steel, which can greatly reduce costs while ensuring the temperature measurement effect.

[0022] In practice, the device is connected to the device under test via the process connection thread 13. Heat is transferred to the outer wall of the circular detection end 14, and then the heat passes through the wall of the circular detection end 14 and comes into contact with the temperature switch core 15. Since the circular detection end 14 is circular, heat can enter the interior of the circular detection end 14 from more surfaces and quickly. As a result, the surface of the temperature switch core 15 can also receive heat quickly, thereby enabling the temperature switch core 15 to obtain temperature information more quickly and accurately, and thus reflect the temperature status of the surrounding environment in a timely manner.

[0023] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
