Description
Technical field
The present invention relates to delay switch product technical field, be specifically related to a kind of heat-sensitive type delay switch.
Background technology
AT STATION, airport, the public place such as market, usually arranging public electric appliances to facilitate the public, in order to save the energy, cutting the waste, delay switch is usually used in the on/off controlling above-mentioned public electric appliances.Delay switch has easy to use, and automatic time delay disconnects the feature of path, avoids the public after using public electric appliances, forgets the waste that powered-down causes.
Summary of the invention
The object of the present invention is to provide a kind of heat-sensitive type delay switch, after connection circuit, can time delay open circuit, and structure is simple, low cost of manufacture, easy to use.
To achieve these goals, the technical scheme that the present invention proposes is:
A kind of heat-sensitive type delay switch, comprise support, button, movable contact spring, fixed touching plate, leading-out terminal, piston, airtight groove, described movable contact spring is connected described leading-out terminal with described fixed touching plate, and described movable contact spring and described fixed touching plate are all horizontally located on described support, described movable contact spring is positioned at above described fixed touching plate, described button activity to be arranged on described support and to be positioned at above described movable contact spring, described piston to be arranged on described movable contact spring and towards described fixed touching plate, described airtight groove to be arranged on described fixed touching plate and towards described movable contact spring, described airtight trench bottom is provided with cooling gas check valve, described airtight groove top is provided with air vent hole.
As the heat-sensitive type delay switch that the present invention improves further, also comprise push rod, back-moving spring, described push rod upper end connects described button, described push rod lower end is positioned at above described movable contact spring through described support, and described back-moving spring is between described button and described support and be set on described push rod.
Heat-sensitive type delay switch provided by the present invention, press described button and can connect circuit, described piston is moved downward and is discharged by cooling gas check valve by the air of described airtight groove simultaneously, thus under external atmospheric pressure effect, described movable contact spring and described fixed touching plate keep in touch, after described movable contact spring and described fixed touching plate are energized a period of time, because heating makes the air in described airtight groove expand, until described piston rises to the position of described air vent hole, ambient atmosphere enters in described airtight groove by described air vent hole, described movable contact spring and described fixed touching plate disconnect, thus realize the function of time delay open circuit, and structure is simple, low cost of manufacture, easy to use.
Accompanying drawing explanation
