[0002] A thermostat is a device that can sense the ambient temperature and control the operation of equipment (such as heating or cooling equipment) according to the set temperature value. It is mainly composed of temperature sensors, controllers and control output interfaces. The temperature sensor is responsible for detecting the actual temperature of the surrounding environment, and the controller compares the actual temperature with the set temperature. When the actual temperature deviates from the set temperature to a certain extent, the heating, cooling equipment, etc. is turned on or off through the control output interface, so as to realize the adjustment and control of temperature.

[0003] Thermostats are widely used in many fields such as home (such as air conditioners, electric heaters), industry (such as industrial furnaces, reaction kettle temperature control), agriculture (such as greenhouse temperature control), etc. The purpose is to keep the environment temperature in a suitable and stable range to meet different needs such as human comfort, industrial production process requirements, plant growth conditions, etc.

[0004] However, the existing structure of the thermostat cannot control the temperature at different temperatures during use, and the use occasion is limited, so it is necessary for the industry practitioners to develop a protection device suitable for the same occasion and needing to control the temperature at different temperatures. SUMMARY

[0025] See Figs. 1-6A preferred embodiment of the present invention provides a temperature control protection device, comprising a housing assembly 1, an adjustable temperature control assembly 2, a protector assembly 3, a left terminal 4, and a right terminal 5.

The lower ends of the left terminal 4 and the right terminal 5 are exposed from the housing assembly 1, and the left terminal 4 and the right terminal 5 are respectively connected to the adjustable temperature control assembly 2 and the protector assembly 3. The adjustable temperature control assembly 2 includes an adjusting nut 6, a temperature sensing rod 7, a pressure plate 8, a temperature adjusting spring 9, and a copper tube 10, and the temperature sensing rod 7 and the copper tube 10 are both exposed from the housing assembly 1. The protector assembly 3 includes two temperature limiting terminals 11 connected to the left terminal 4 and the right terminal 5 respectively, a double plate 12, and a temperature limiting push rod 13.

[0026] Preferably, the housing assembly 1 includes a housing 14 and a base 15, and the adjustable temperature control assembly 2, the protector assembly 3, the left terminal 4 and the right terminal 5 are all fixedly installed in the cavity formed by the housing 14 and the base 15.

[0027] Preferably, one end of the left terminal 4 and the right terminal 5 are respectively connected to the corresponding temperature-limiting terminal 11 via a temperature-limiting spring 16 to achieve connection with the protector assembly 3. The other end of the left terminal 4 is connected to the wiring post, and the other end of the right terminal 5 is connected to the temperature-adjusting spring 9 via a temperature-adjusting spring 9. The temperature-adjusting spring 9 is connected to the wiring post via a wiring plate 17. That is, the left terminal 4 and the right terminal 5 are connected to the adjustable temperature control assembly 2.

[0028] Preferably, the adjustable temperature control component 2 has a temperature sensing rod 7 that is inserted into the inner cavity of the copper tube 10. The temperature sensing rod 7 is riveted to the lower end of the copper tube 10. The upper end of the temperature sensing rod 7 passes through the double plate 12, the temperature limiting push rod 13, and the pressure plate 8 from bottom to top, and is threadedly connected to the adjusting nut 6. One end of the pressure plate 8 is fixedly installed in the inner cavity of the cover 14, and the other end is detachably contacted with the temperature regulating spring 9. The lower end of the adjusting nut 6 abuts against the pressure plate 8. The temperature limiting push rod 13 is movably installed in the inner cavity of the cover 14. The double plate 12 is in contact with the lower end of the temperature limiting push rod 13, and the upper end of the temperature limiting push rod 13 is detachably contacted with the temperature limiting spring 16. The double plate 12 is installed in the base 15 through the double plate compartment 18, and the upper end of the copper tube 10 is installed on the base 15 through the double plate compartment 18.

[0029] Preferably, the temperature limiting push rod 13 has a mating post 19 that passes through the pressure plate 8.

[0030] Preferably, it also has a handle 20 that cooperates with the adjusting nut 6. The handle 20 is rotatably mounted on the cover 14, and the adjusting nut 6 is fixedly mounted in the inner cavity of the handle 20.

[0032] The working principle of this utility model is as follows:

[0033] The lower end of the temperature sensing rod 7 is fixedly connected to the copper tube 10, and the upper end of the temperature sensing rod 7 is threadedly connected to the adjusting nut 6. One end of the pressure plate 8 is fixedly installed in the inner cavity of the cover 14, and the other end is detachably contacted with the temperature regulating spring 9. Thus, one end of the pressure plate 8 is fixed, while the other end is in a free state. By rotating the adjusting nut 6, a force can be applied to the pressure plate 8, controlling the contact distance between its front end and the temperature regulating spring 9. Based on the above principle, the set temperature can be achieved. By placing the copper tube 10 in the temperature field that needs to be disconnected and rotating the adjusting nut 6 until the switch is off, the setting is completed. During use, due to the different expansion coefficients of the temperature sensing rod 7 and the copper tube 10 after heating, the outer copper tube 10 will expand more than the inner temperature sensing rod 7, thus creating a displacement difference that drives the pressure plate 8 to move and achieve the disconnection action. However, under certain circumstances, if the adjustable temperature control component 2 fails and the disconnection action is not performed even when the temperature reaches a certain limit, the double plate 12 of the protector component 3 can take over the work. When the temperature exceeds the set range of the double plate 12, the double plate 12 arches up, pushing the temperature limiting push rod 13 upward, and the temperature limiting spring 16 separates from the temperature limiting terminal 11, thus achieving the disconnection action.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
