Description
Technical field
The utility model relates to a kind of steam cock, more particularly, relates to a kind of improved electric kettle steam cock.
Background technology
The steam cock of existing domestic electric heating kettle generally is by being installed in temperature-sensitive bimetal leaf on the kettle as temperature sensing medium.Yet the temperature-sensitive bimetal leaf exists difficulty of processing bigger more, and temperature-controlled precision is relatively poor, and corrosion-resistant is easily got rusty and caused losing efficacy problems such as the most of dependence on import of material; In use, its integrally-built stability is bad, and vibrations are arranged slightly, is easy to generate misoperation, or Yin Wendu control is inaccurate, causes jumping early or boiling time long.
The utility model content
Technical problem to be solved in the utility model provides the improved electric kettle steam cock that a kind of operating temperature is accurate, the recovery action has a narrow range of temperature, response speed is fast, the life-span is long and be difficult for not being subjected to weather and ambient influnence.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of improved electric kettle steam cock, in the base of kettle, an active lever is installed in the mode of rotating, the front end of this active lever forms a switch key outward by reaching kettle in the base, and one first actuating strut lower end is fixed on above the active lever; In described base, also be installed with a cuvette housing and this cuvette housing is positioned at directly over first actuating strut, in the cuvette housing, be provided with soft magnetism and Hard Magnetic and Hard Magnetic and be positioned at above the soft magnetism, between soft magnetism and Hard Magnetic, be provided with spring; Be positioned at above the movable contact spring being provided with movable contact spring and static contact and static contact between first actuating strut and the cuvette housing, be provided with movable contact and be provided with and the corresponding stationary contact of described movable contact at the static contact basal surface at the movable contact spring upper surface; One second actuating strut upper end is stretched in the cuvette housing and with soft magnetism and is connected and fixed, this second actuating strut lower end and movable contact spring are connected and fixed, and first actuating strut upper end and movable contact spring close-fitting, when down press switch key, upwards push up movable contact spring first actuating strut upper end.
Described soft magnetism is that soft magnetic ferrites are made.
The utility model is owing to adopted said structure, in use, switch key is down pressed, and first actuating strut upwards pushes up movable contact spring, thereby moving contact, static contact are touched mutually, second actuating strut also upwards pushes up soft magnetism in the process that movable contact spring rises simultaneously, when soft magnetism rise to arrive certain apart from the time, magnetic force will be greater than the spring force of spring, at this moment, the mutual adhesive of Hard Magnetic and soft magnetism, power connection; Be accompanied by the continuous rising of temperature, when reaching the limiting temperature of soft magnetism, soft magnetism is not attracted by Hard Magnetic, and at this moment, soft magnetism breaks away from Hard Magnetic fully under the effect of spring, promotes second actuating strut simultaneously with movable contact, stationary contact two contacts separately, and power supply disconnects.In the utility model, utilize soft magnetism to match with Hard Magnetic, by utilizing soft magnetism near Curie temperature, can lose magnetic conductivity, can be soft magnetic ferrites as soft magnetism makes, thereby movable contact, stationary contact are in contact with one another or separately realize the closed of switch or open, so the utlity model has operating temperature accurately, recover that action has a narrow range of temperature, response speed is fast, the life-span is long and the difficult advantages such as weather and ambient influnence that are not subjected to, as temperature control precision of the present utility model can be controlled at according to concrete requirement 〉=± 0.5 ℃.The utility model can be widely used in household electric appliances, and temperature control of other various installations, temperature monitoring, overtemperature prote etc.
After the detailed description of reading embodiment of the present utility model in conjunction with the accompanying drawings, it is clearer that characteristics of the present utility model and advantage will become.
Description of drawings
Fig. 1 is the mounting structure schematic diagram of embodiment of the present utility model; And
Fig. 2 is an A partial enlarged drawing partly shown in Figure 1.
The specific embodiment
With an embodiment the utility model is described in further detail below, but should illustrates, protection domain of the present utility model is not limited only to this.
Consult Fig. 1 and Fig. 2, a kind of improved electric kettle steam cock, in the base 2 of kettle 1, an active lever 11 is installed in the mode of rotating, wherein, active lever 11 is to connect on the support iron 14 that is seated in the base 2 and by screw 15 to reach rotating purpose, the front end of this active lever 11 is outer and form a switch key 16, one first actuating struts 9 lower ends and be fixed on above the active lever 11 by reaching kettle 1 in the base 2; Also being installed with a cuvette housing 3 and this cuvette housing 3 in base 2 is positioned at directly over first actuating strut 9, being provided with soft magnetism 8 and Hard Magnetic 4 and Hard Magnetic 4 in cuvette housing 3 is positioned at above the soft magnetism 8, soft magnetism 8 is made for soft magnetic ferrites, is provided with spring 5 between soft magnetism 8 and Hard Magnetic 4; Be positioned at above the movable contact spring 7 being provided with movable contact spring 7 and static contact 8 and static contact 8 between first actuating strut 9 and the cuvette housing 3, be provided with movable contact 12 and be provided with and described movable contact 12 corresponding stationary contacts 13 at static contact 8 basal surfaces at movable contact spring 7 upper surfaces; One second actuating strut, 10 upper ends are stretched in the cuvette housing 3 and with soft magnetism 8 and are connected and fixed, these second actuating strut, 10 lower ends and movable contact spring 7 are connected and fixed, and first actuating strut, 9 upper ends and movable contact spring 7 close-fittings, when down pressing switch key 16, upwards push up movable contact spring 7 first actuating strut, 9 upper ends.
