Abstract
The utility model relates to a memory alloy micro temperature controller, which comprises a bottom base, an upper cover, etc. The right middle part in the bottom base is provided with a static contact. The lower middle part in the bottom base is provided with an elastic contact plate with a movable contact arranged on the right upper part. The movable contact and the static contact are mutually corresponding. A pushing rod passes through the center of a support bracket to be placed on the upper middle part of the elastic contact plate. The upper part of a bottom rack is provided with the support bracket. The upper middle part in the support bracket and the top part of the pushing rod are provided with double-stroke memory alloy temperature sensing plate in a butterfly shape. The upper convex and lower concave functions of the double-stroke memory alloy temperature sensing plate in a butterfly shape are used for enabling the movable contact and the static contact to rapidly move to switch on or off a circuit in order to obtain the purpose of temperature control or circuit protection.
Description
Affiliated technical field
The utility model is addressed a kind of temperature controller that belongs to household electrical appliance, is particularly useful for the thermostat of microwave oven, electric heater, electric shower-bath, electric heater, coffee pot, water dispenser etc.
Background technology
At present, known thermostat mostly is bimetallic temperature sensor to be formed, and its action is less, and motive force is little, and the quality instability haves much room for improvement.
Summary of the invention
Less in order to overcome existing thermostat action, motive force is little, the unsettled deficiency of quality, the utility model provide a kind of memorial alloy minisize temperature controller, utilize the epirelief, recessed of the butterfly-shaped thermal sensitive piece of round trip memorial alloy, thermostat is moved rapidly, motive force is big, and the temperature control sensitivity is simple in structure, profile is small and exquisite, long service life.
The technical scheme of the utility model technical solution problem is: comprise base and loam cake etc., right middle is equipped with fixed contact in base, the spring contact sheet that its upper right quarter is equipped with moving contact is equipped with at the middle part down in base, dynamic and static contact in correspondence with each other, push rod passes the carriage center and is placed in middle part on the spring contact sheet, on underframe top carriage is housed, in carriage on the middle part and the push rod top the butterfly-shaped thermal sensitive piece of round trip memorial alloy is housed.By the butterfly-shaped thermal sensitive piece epirelief of round trip memorial alloy, recessed, effect is moved dynamic/static contact rapidly, is switched on or switched off circuit, thereby reaches the purpose of temperature control or protective circuit.Round trip memorial alloy butterfly thermal sensitive piece adopts NiTi, NiTi copper, copper-aluminium and beryllium X and copper aluminium manganese X memorial alloy, and it handles to reach through special high low temperature circulation round trip memory has the round trip memory effect, i.e. memory raised position during low temperature; Remember recessed state during high temperature.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Embodiment
In Fig. 1, spring contact sheet 6 is fixed on goes up the middle part in the base 5, and moving contact 4 is equipped with in its upper right side, and right middle is equipped with fixed contact 3 in the base 5 on its top, and push rod 7 passes the middle part of going up that carriage 2 centers are placed in spring contact sheet 6.Round trip memorial alloy butterfly thermal sensitive piece 1 is installed on the carriage 2 middle part and is pressed on the push rod 7, and loam cake 8 is installed in carriage 2 tops.
In normal temperature range, the butterfly-shaped thermal sensitive piece 1 of round trip memorial alloy is in the epirelief state, and dynamic and static contact contacts with each other, and is "on" position.When temperature reached 30～200 ℃ of set points of temperature, the 1 downward concavity attitude motion of round trip memorial alloy butterfly thermal sensitive piece made push rod descending, spring contact sheet 6 is depressed, and fixed contact 4 leaves with moving contact 3, cuts off the electricity supply, heater element in the electrical equipment quits work, and temperature descends.When butterfly-shaped thermal sensitive piece 1 temperature of round trip memorial alloy dropped to certain value, the butterfly-shaped thermal sensitive piece 1 of round trip memorial alloy was in the epirelief state, and dynamic and static contact 3,4 is contacted once more, and energized works on electrical equipment, thereby realized the purpose of temperature control.
Claims (2)
1. a memorial alloy minisize temperature controller comprises base and loam cake etc., it is characterized in that right middle is equipped with fixed contact in base, the spring contact sheet that its upper right quarter is equipped with moving contact is equipped with at the middle part down in base, and dynamic and static contact in correspondence with each other, push rod passes the carriage center and is placed in middle part on the spring contact sheet, on underframe top carriage is housed, in carriage on the middle part and the push rod top the butterfly-shaped thermal sensitive piece of round trip memorial alloy is housed.
2. memorial alloy minisize temperature controller according to claim 1 is characterized in that: the butterfly-shaped thermal sensitive piece of round trip memorial alloy adopts NiTi, nickel-titanium-copper alloy or copper-aluminium and beryllium X and copper aluminium manganese X-alloy.
