Abstract
The utility model relates to an electric water pot thermoregulator for preventing water dry-cooking, comprising a body, a movable contact piece and a stationary contact piece arranged on the body, a temperature-sensing bimetal sticky stickily arranged on the heating face, a dry burning control push rod arranged between the temperature-sensing bimetal and the movable contact piece, and an arm rod articulated with the body. One end of the arm rod being away from the movable contact piece controls the switch of the external circuit and is provided with an elastic reset device. One end of the arm rod near the movable contact piece is provided with a projection, under the pressing state of the movable contact piece, the movable contact piece and the projection are pressed, and one end of the arm rod being away from the movable contact piece makes the circuit switch of the external circuit cut off. Compared with prior art, the interior circuit of the utility model separates, and meanwhile the external circuit is made to be separated, so the breakage of the heater caused by the dry burning iterative switching and other unsafe factors are not induced.
Description
Technical field
The utility model relates to a kind of Domestic electric kettle thermostat, and specifically a kind of insulating pot can prevent the thermostat of dry combustion method.
Background technology
General Domestic electric kettle all has the thermostat of control temperature,, if do not controlled, will cause insulating pot to burn out, even can cause fire during boiled or dry combustion method when water.Insulating pot thermostat commonly used has generally comprised housing, movable contact spring, static contact, the three-pin plug that connects power supply, the temperature-sensitive bimetal leaf, form force transmission and act on the movable contact spring of two utmost points by driving lever, driving lever spring, the push rod that opens circuit, dry combustion method push rod, connecting rod, the separation that realizes dynamic and static contact with contact.As the patent No. is that 00242643.9 Chinese patent discloses a kind of thermostat.When reaching a design temperature, the temperature-sensitive bimetal leaf is bent downwardly, and push rod is pushed away downwards, and push rod moves down conducting strip, and movable contact spring and static contact point are thrown off, thus the internal circuit disengagement, and electrothermal device quits work.But insulating pot still contact is charged, and external circuit is still thrown off, cause easily dry combustion method repeatedly break-make cause the damage and the unsafe factor of heater.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of insulating pot anti-dry heating temperature controller at above-mentioned prior art present situation, can stop dry combustion method break-make phenomenon repeatedly, promptly not only throws off internal circuit, and external circuit is thrown off.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of insulating pot anti-dry heating temperature controller, comprise body, be arranged on the movable contact spring on the body, static contact, can post the temperature-sensitive bimetal leaf on heating face, be arranged on the dry combustion method control push rod between temperature-sensitive bimetal leaf and the movable contact spring, the armed lever hinged with body, armed lever is handled the external circuit switch away from movable contact spring one end, and be provided with an elasticity reset device, close movable contact spring one end at described armed lever is provided with a protuberance, under the movable contact spring pressed status, movable contact spring with protuberance is pressed, armed lever disconnects the external circuit contactor away from movable contact spring one end.
Armed lever can be provided with projection away from movable contact spring one end, by projection external circuit contactor break-make.
Compared with prior art, the utility model is provided with a protuberance at close movable contact spring one end of armed lever, under the movable contact spring pressed status, movable contact spring with protuberance is pressed, armed lever disconnects the external circuit contactor away from movable contact spring one end.Like this, when reaching a design temperature, the temperature-sensitive bimetal leaf is bent downwardly, and internal circuit is thrown off, and simultaneously external circuit is thrown off, can not cause dry combustion method repeatedly break-make cause damage and other unsafe factors of heater.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
A kind of insulating pot anti-dry heating temperature controller shown in Fig. 1,2,3 and 4, comprise body 1, be arranged on movable contact spring 2, static contact 3 on the body 1, can post the temperature-sensitive bimetal leaf 4 on insulating pot heating face, be arranged on the dry combustion method control push rod 6 between temperature-sensitive bimetal leaf 4 and the movable contact spring 2, the armed lever 7 hinged with body 1, armed lever 7 are hinged by pivot 8 and body 1.Armed lever 7 is handled the external circuit switch away from movable contact spring 2 one ends, and is provided with an elasticity reset device.Elasticity reset device is general prior art, and embodiment is disclosed to be that 5, one sections of spring leafs are fastened on the body 1, and the other end is fastened on the armed lever 7.Can also adopt other elasticity reset devices such as wind spring.Close movable contact spring 2 one ends at described armed lever 7 are provided with a protuberance 9, under movable contact spring 2 pressed status, movable contact spring 2 with protuberance 9 is pressed, armed lever 7 rotates to an angle around pivot 8 away from movable contact spring 2 one ends, armed lever 7 is upwards lifted, projection 10 also upwards lifts, and the external circuit contactor is disconnected.Armed lever 7 is provided with projection 10 away from movable contact spring 2 one ends, makes the external circuit switch motion with break-make by projection 10.Making the external circuit switch motion is routine techniques, can adopt other mode break-makes.
Claims (2)
1, a kind of insulating pot anti-dry heating temperature controller, comprise body, be arranged on movable contact spring, static contact on the body, can post the temperature-sensitive bimetal leaf on heating face, be arranged on the dry combustion method control push rod between temperature-sensitive bimetal leaf and the movable contact spring, the armed lever hinged with body, armed lever is handled the external circuit switch away from movable contact spring one end, and be provided with an elasticity reset device, it is characterized in that being provided with a protuberance at close movable contact spring one end of described armed lever, under the movable contact spring pressed status, movable contact spring with protuberance is pressed, armed lever disconnects the external circuit contactor away from movable contact spring one end.
