A thermostat safety device

Abstract

The invention discloses a temperature control safety device, A thermosensitive switching device the technical scheme mainly comprises an upper fuse plate and a lower fuse plate fixed on an insulatingring frame of the thermostat and connected with a temperature control device of the thermostat, and a fixing piece fixed to the lower end of the insulating ring frame and a stopper, wherein the stopper comprises a thermally conductive metal sleeve clamped to the fixing sheet and provided with an upper end opening, a hot melt filled in the heat conductive metal sleeve and a jacking rod inserted inthe heat conductive metal sleeve for jacking the lower fuse and the upper fuse, wherein the bottom end part of the heat conductive metal sleeve is communicated with the outside of the heat conductivemetal sleeve, and the bottom end of the stopper is in contact with the electric heating work piece; The temperature control safety device has the effect of convenient installation and fixation.

Description

technical field [0001] The present invention relates to a thermosensitive switch device, more specifically it relates to a thermostat safety device. Background technique [0002] At present, general thermostats, especially those used in household appliances such as electric irons, have safety devices for safety reasons. , the safety device can prevent the equipment from continuing to run through the function of tripping. [0003] For example, the Chinese patent with the authorized announcement number CN202067726U discloses a thermostat safety device, including an upper safety plate, a lower safety plate, an insulating push rod and a fusible material at the bottom of the insulating push rod, and the fixing of the upper safety plate and the lower safety plate. The end is fixed on the insulating ring frame of the thermostat, and the insulating push rod supports the lower safety plate and the upper safety plate to make the free ends of the two contact, and the lower safety plat...

Problems solved by technology

[0006] Similar to the above in the prior art, when the work of the electrothermal work piece is close to the over-limit temperature, the hot melt melts, and the lower end of the ejector rod loses its restriction, so that the ejector rod cannot upwardly support the lower safety plate, and the lower safety plate will contact with the lower safety plate after reset. The upper fuse is separated to complete the tripping and power-off work; however, no matter what technology is used, when installing the thermostat, it is necessary to open or indirectly open a storage tank for the installation of the heating melt on the electric heating work piece. However, in the prior art, it is necessary to consider the shape and size of the hot melt when setting up the accommodating groove 11 in the electrothermal work piece 1, so the precision is high. However, the electrothermal work piece is usually stamped and formed, and it is difficult to ensure that the accommodating groove is opened on the top. Accuracy, so the processing cost of electrothermal workpieces has been rising
