Technical Field

[0001] The utility model relates to the technical field of temperature control switches, in particular to a temperature control switch with a safety function. Background Art

[0002] A temperature control switch is a switch device used to control temperature. It can monitor the ambient temperature and control the switch state of related equipment or systems according to the preset temperature threshold to maintain the set temperature range. Temperature control switches are widely used in various household appliances, industrial equipment and buildings to protect equipment from overheating or overcooling and improve the operating efficiency and life of the equipment.

[0003] Patent No. "CN202003871U" discloses a "temperature control switch". This device can effectively increase the heat dissipation area of ​​the temperature control controller by the heat dissipation profile by covering the temperature control controller in the extended accommodation cavity of the heat dissipation profile, so that the heat accumulated on the surface of the temperature control controller can be dissipated faster; since general temperature control switches are exposed in design, they are easily affected by the external environment during use, such as moisture, dust, etc., which may cause the switch to be damaged or its life to be shortened during use, but the above-mentioned device has not made any improvements to this problem, and the overall practical effect is poor. Utility Model Content

[0004] The purpose of the present utility model is to solve the above-mentioned problem and to propose a temperature control switch with a safety function, which improves the existing temperature control switches which are all exposed in design and are easily affected by the external environment when in use, such as moisture, dust, etc., which may cause the switch to be damaged or its life to be shortened during use.

[0005] A temperature-controlled switch with a safety function comprises a temperature-controlled switch body: a safety protection mechanism is arranged on the side of the temperature-controlled switch body, an encapsulation protection mechanism is arranged on the side of the safety protection mechanism, an interference installation mechanism is arranged on the side of the encapsulation protection mechanism, the safety protection mechanism comprises a connecting wire and an overload protector, a connecting wire is connected and installed at the bottom end of the temperature-controlled switch body, and an overload protector is connected and installed at the middle section of the connecting wire.

[0006] Preferably, the encapsulated protection mechanism includes a first encapsulated shell, a second encapsulated shell and a resisting block, the first encapsulated shell and the second encapsulated shell are arranged outside the temperature control switch body, and two groups of resisting blocks are symmetrically arranged on the side outer wall of the first encapsulated shell.

[0007] Preferably, two groups of interference slots are symmetrically formed on the inner wall of the side of the second encapsulating shell, and the interference block and the interference slot are engaged with each other.

[0008] Preferably, the side outer walls of the first encapsulating shell and the second encapsulating shell are both provided with mounting grooves, and the mounting grooves are consistent with the external parts of the temperature control switch body.

[0009] Preferably, the interference mounting mechanism comprises a positioning mounting plate, and the side outer walls of the first encapsulating shell and the second encapsulating shell at the bottom positions are symmetrically provided with positioning mounting plates.

[0010] Preferably, a thread groove is provided through the outer wall of the top end of the positioning mounting plate, and a threaded mounting is performed between the thread groove and the positioning bolt.

[0011] Preferably, a supporting bottom plate is disposed below each of the first encapsulating shell and the second encapsulating shell, and placement grooves are symmetrically and evenly spaced on the outer wall at the top end of the supporting bottom plate.

[0012] Preferably, a resisting spring is connected between the bottom inner wall of the placement groove and the bottom outer wall of the first encapsulation shell.

[0013] The beneficial effects of the utility model are:

[0014] 1. When the temperature control switch with the insurance function is in use, the first encapsulation shell, the second encapsulation shell, the resistance card block and the resistance card slot are arranged, and the engagement relationship between the resistance card block and the resistance card slot is utilized so that the first encapsulation shell and the second encapsulation shell can be well encapsulated and installed on the outside of the temperature control switch. Furthermore, through the above-mentioned encapsulation design, the temperature control switch can effectively prevent dust, moisture, liquid and other external environmental substances from invading the inside of the temperature control switch, thereby extending its service life. The overall structural design is simple and has good practical effect.

[0015] 2. When the temperature control switch with insurance function is in use, an overload protector is installed on the connecting line between the temperature control switch and the controlled device. The overload protector can protect the device from damage by overload current and ensure the safe operation of the device. When the internal current of the line is overloaded, the overload protector can help to disconnect the circuit in time to avoid overheating or damage to the equipment, and also extend the service life of the equipment. Further, the locking effect of the positioning bolt and the equipment is combined with the reverse resistance support effect of the resistance spring, so that the temperature control switch can achieve a stable installation effect, thereby ensuring its subsequent safe use on the basis of stable installation of the temperature control switch, and the overall practical effect is good.
