Description
Technical field
The utility model relates to kitchen utensils, specifically a kind of thermal-insulation electric heating kettle with safety device.
Background technology
Thermal-insulation electric heating kettle has heat insulation effect because of its kettle as double walled vacuum structure, can be incubated after water is boiled to boiling water, no longer needs water to turn to contain in vacuum flask.
Thermal-insulation electric heating kettle is sealed when heating, and measured the water temperature in kettle by temperature monitoring elements, when the water temperature value measured exceedes preset value, circuit board controller is cut off the electricity supply in time.After Long-Time Service, the sensitivity decrease of temperature monitoring elements, often there is the inaccurate problem of thermometric, cause power supply not power-off in time, in addition, circuit board controller is out of control also can cause kettle continuous heating, in both cases, the capacity of air bleeding valve is less than the generation of steam, and pot lid can be blown up because kettle internal vapor pressure is excessive, there is potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model overcomes the defect that above-mentioned prior art exists, and provides a kind of thermal-insulation electric heating kettle with safety device, when the steam pressure in kettle is excessive, can disconnecting circuit in time, and avoid pot lid to be blown up.
For this reason, the technical solution adopted in the utility model is as follows: the thermal-insulation electric heating kettle of band safety device, comprise double walled kettle body, pot lid, the upper oral part of kettle body upwards extends to form edge, pot lid is plugged in edge, its technical characteristic is, it also comprises a safety device, described safety device comprise be arranged on kettle and be connected with it and with power electric microswitch, be positioned at frizzen above microswitch, at least one group of pot lid lifting assembly being arranged on pot lid; The upper end evagination of described frizzen is in kettle body;
Described pot lid lifting assembly comprises fixed block, is connected on fixed block and the movable block that can slide up and down relative to fixed block, described fixed block evagination is in the sidewall of pot lid, the inwall on kettle edge is with it formed the projection to fixed block vertical spacing, the end face of movable block and bottom surface are all inconsistent with the inwall of pot lid;
When the tangible kettle of pot lid lid with it time, pot lid promote frizzen move down, trigger microswitch make its close, connection circuit, kettle is able to normal heating; When the steam pressure in kettle is excessive, steam is by pot lid upwards jack-up, and movable block moves up relative to fixed block thereupon, and the bottom surface of pot lid no longer offsets with the upper end of frizzen, and microswitch is opened, disconnecting circuit, and kettle stops heating.
By setting up microswitch, when steam pressure is excessive in kettle, power-off in time can stops heating, avoiding the pot lid that continuous heating causes and blow up phenomenon, improve security performance; By arranging pot lid lifting assembly, make the rising of pot lid under steam promotes can be steady, need when reheating or be incubated, promote pot lid downwards, the decline of pot lid also can be steady.
As improvement, the sidewall of described frizzen is formed a position limiting convex ring, the roof of this position limiting convex ring and the inwall of kettle body offset; Described frizzen also overlaps outward the first back-moving spring, and the upper end of the first back-moving spring and the diapire of position limiting convex ring offset, and lower end and microswitch offset; When frizzen move down, trigger microswitch time, the first back-moving spring is in confined state.This setting, makes the easy for installation of frizzen, and can not depart from station, skids off in kettle body, and the first back-moving spring by frizzen upwards jack-up after pot lid moves up, can make it overcome gravity and leave microswitch, ensure that microswitch disconnects smoothly.
As improvement, the lateral surface of described movable block is formed at least one slide bumping, described fixed block offers the sliding tray corresponding with slide bumping; Described movable block is formed the locating dowel of multiple vertical setting, fixed block is offered with locating dowel with the use of locating ring; When movable block moves up and down with pot lid, slide bumping slides up and down in sliding tray, and locating dowel is slided in locating ring.This setting, makes movable block moving up and down steadily relative to fixed block, thus makes the lifting of pot lid steady.
As improvement, described locating dowel is also overlapped outward the second back-moving spring, and the upper end of the second back-moving spring and the bottom surface of locating ring offset, and lower end and movable block offset; When movable block is with when pot lid moves, the second back-moving spring is in confined state.This setting, make in kettle after steam pressure reduction, movable block can push up downwards by the second back-moving spring, makes it reset, thus pot lid is resetted.
As improvement, described pot lid lifting assembly has two groups, and is symmetricly set in pot lid.This setting, makes the lifting of pot lid more steady.
The beneficial effects of the utility model are mainly reflected in: when the steam pressure in kettle is excessive, and pot lid lifting assembly makes pot lid can by steam upwards jack-up reposefully, and microswitch disconnects, thus disconnecting circuit in time, stop heating, avoid pot lid and blown up.
