Abstract

The invention relates to the technical field of temperature control sensors, in particular to a sensor triggering structure. The sensor triggering structure comprises a base. A thermo-sensitive assembly and an anti-dry burning device are arranged inside the base. The upper end of the base is provided with an upper cover which independently acts relative to the base. A compression spring is arranged between the upper cover and the base. The upper end opening of the base is provided with a fixed plate corresponding to the upper cover. An elastic reed is arranged between a temperature sensing sheet and the fixed plate. A triggering component of the anti-dry burning component is arranged on the fixed plate arranged under the temperature sensing sheet. The thermo-sensitive assembly is arranged on one side, provided with the temperature sensing plate, of the fixed plate. According to the sensor triggering structure, the structure is reasonable, the upper cover is displaced up and down along a guiding shell relative to the base, and the upper cover is prevented from horizontally shifting in the triggering process so that the sensitivity of a sensor cannot be influenced. In the downward pressing process of the upper cover, the upper cover is in sequential contact with the thermo-sensitive assembly and the temperature sensing piece, and the triggering action is accurate and stable. Due to the fact that a sensing component inside the base is fixedly arranged, the problem of thread loosing of lead welding spots can be effectively lowered, and the service life and the yield are improved.

Description

technical field

[0001] The invention relates to the technical field of temperature control sensors, in particular to a sensor trigger structure. Background technique

[0002] Chinese patent CN201422761Y discloses a micro switch type anti-dry device, including a mounting cup, a micro switch and a switch support plate, the micro switch is set in the mounting cup, the mounting cup is installed on the switch support plate, and installed There is a return spring between the cup and the switch support plate, and the switch support plate is fixed on the installation base plate. When in use, the micro switch is operated under the installation cup to connect the heating circuit on the installation base plate. There are thermal components connected in series on the heating circuit, and the installation cup When released, the heating circuit is disconnected.

[0003] There are many defects in this structural arrangement. In practical applications, the working parts in the sensor are f...
