Description

Stable manual reset temperature controller

Technical Field

The application relates to the technical field of temperature controllers, in particular to a stable manual reset temperature controller.

Background

At present, temperature controllers are mostly adopted in a plurality of heating circuits to control the on-off state through temperature, for example, a reset temperature controller adopted in the using process of a water dispenser is divided into a manual reset temperature controller and an automatic reset temperature controller.

Related art for example be CN206451657U discloses a manual temperature controller that resets, including casing and release link, be provided with shell fragment, push rod, static contact and moving contact in the casing, the casing is provided with the via hole, and the release link includes a card support post and button, and a card support post one end is connected with the button, and the other end is provided with the dop, and the release link inserts the via hole of casing through a card support post, and the release link is provided with axial lumen, and the lumen inlays and is equipped with the anticreep pole.

In the above-described related art, the inventors consider that: when the temperature controller that resets uses, because the diameter of support card support column and anticreep pole is less than the button for people are when the slip direction of the direction skew anticreep pole of pressing the button, support the easy rupture of card support column box anticreep pole, make the life of the temperature controller that resets shorter.

SUMMERY OF THE UTILITY MODEL

In order to increase the life who resets the temperature controller, the purpose of this application is to provide a firm type manual reset temperature controller.

The application provides a firm manual reset temperature controller adopts following technical scheme:

the utility model provides a temperature controller resets manually that stabilizes, includes the casing and set up in lid on the casing, be provided with temperature sensing video disc, push rod, static contact and moving contact in the casing, the temperature sensing video disc is used for promoting the push rod will the moving contact breaks away from the static contact, the casing is kept away from the one end of lid slides and is provided with the release link, a plurality of fixed strips of fixedly connected with on the circumference lateral wall of release link, set up on the casing and supply the spout that fixed strip and release link together slided, the release link is used for promoting the push rod drives the temperature sensing video disc reversal will the moving contact butt in the static contact.

By adopting the technical scheme, when water in the water dispenser is boiled, the temperature sensing disc starts to bend towards the inside of the shell at high temperature so as to push the push rod towards the direction far away from the cover body, so that the moving contact is separated from the static contact under the pushing of the push rod, the power supply of the water dispenser is disconnected, and the automatic disconnection of the water boiling power supply is realized. Then the reset rod is pressed towards the inside of the shell to drive the reset rod and the fixing strip to slide towards the direction of the cover body in the sliding groove together until the reset rod abuts against the push rod, so that the push rod slides towards the direction of the cover body until the push rod abuts against the temperature sensing disc to rotate reversely, the moving contact abuts against the static contact again, and the power supply of the water dispenser is communicated to boil water. Therefore, by arranging the reset rod, the temperature sensing disc is reversed by matching the ejector rod, so that the moving contact is abutted against the fixed contact to communicate the power supply of the water dispenser again, the rigidity strength of the reset rod in the shell is increased by the fixing strip, the stability of the push rod pushed by the reset rod is enhanced, and the service life of the reset temperature controller is prolonged.

Optionally, the fixed strip is located one end fixedly connected with fixed block in the casing, fixedly connected with butt on the cell wall of spout the fixed block is back to the stopper of lid one side, stopper slip butt in on the lateral wall of fixed strip.

Through adopting above-mentioned technical scheme, when the temperature sensing video disc is heated when the inside bending of casing, temperature sensing video disc butt push rod, butt release link towards the casing outside slides when the push rod breaks away from the static contact to make release link and fixed strip slide towards the casing outside in the spout, until the fixed block butt on the fixed strip in the stopper, with the restriction fixed block roll-off spout, and then restriction fixed strip and release link roll-off spout, so that release link and fixed strip jack-up the push rod towards the lid in the spout.

Optionally, the fixed block is back to fixedly connected with sealing strip on the lateral wall of lid, set up the confession on the lateral wall of stopper the seal groove that the sealing strip card was gone into.

Through adopting above-mentioned technical scheme, when release link and fixed strip slided towards the direction of keeping away from the lid in the spout, the fixed block slided outwards along with the fixed strip towards the spout together, and when the fixed block butt was in the stopper, the sealing strip card was gone into in the seal groove to seal between fixed block and the stopper, reduce external dust or water and get into in the casing.
