Abstract
The utility model relates to a thermostat, composed of a housing and a drive rod. A stationary contact is arranged on the housing, and a movable contact is arranged on the drive rod. The utility model is characterized in that a spring sleeve made of the memory alloy is on the drive rod, and the both ends of the spring sleeve are restricted respectively by the housing and the drive rod; a spring sheet is fixed between the drive rod and the housing. When the temperature is higher than the transformation point, the memory spring restores the elongation and pushes the drive rod to move; then a power supply is cut off. After the temperature falls, the drive rod returns the original position under the action of the spring sheet; then the power supply is turned on, so the temperature control is realized. The utility model has the advantages of various forms, simple structure, safe operation, wide application, etc.
Description
The utility model relates to the electronic devices and components field, has specifically just provided a kind of thermostat of making of memory alloy material.
Thermostat has various ways, and wherein modal is double-metal sheet type and temperature-sensitive magnet-type.Their each tool pluses and minuses, double-metal sheet type is simple in structure, volume is little, but temperature is non-adjustable, and temperature-sensitive magnet-type complex structure, temperature control is accurate, but can only can not be incubated by temperature control.
The purpose of this utility model be to provide a kind of simple in structure, temperature is adjustable, and is safe and reliable during use, has the thermostat of bimetal leaf and temperature-sensitive magnet advantage---memorial alloy thermostat concurrently.
Ti-Ni alloy has shape memory effect, and so-called shape memory effect is meant that alloy produces plastic deformation in (transformation temperature is following) stressed back at low temperatures, in case be heated to more than the transformation temperature, it will return to the high temperature shape.Another characteristics of Ti-Ni alloy are---stress-induced martensite phase transformation, its mechanism be alloy under stress, cause martensite to produce in advance, transformation temperature is raise.The utility model is exactly above-mentioned two features of utilizing ti-ni shape memory alloy, adopts suitable structure, realizes that temperature control and temperature control are adjustable.
The utility model is made of parts such as housing and drive rods, and fixed contact is arranged on the housing, and moving contact is arranged on the drive rod, it is characterized in that: 1, the spring housing of being made by memorial alloy is on drive rod, and its two ends are subjected to the constraint of housing and drive rod respectively; 2, with a spring leaf drive rod and housing are fixed up, the effect of spring leaf is that drive rod and housing are coupled together, and makes dynamic and static contact be in normally closed state, and it also plays the effect that makes the rapid return of drive rod in addition.Memory alloy spring then is used for controlling moving contact, and when temperature reaches transformation temperature when above, memory spring returns to the high temperature shape immediately, promotes drive rod and moves, and normally-closed contact is disconnected, and cuts off the electricity supply.By the time memory alloy element is cooled to transformation temperature when following, memory spring shrinks voluntarily, and drive rod automatically resets under the effect of spring leaf, makes the normally-closed contact auto-closing, switches on again, back and forth realizes temperature control thus.Below in conjunction with accompanying drawing in detail embodiment is described in detail.
Accompanying drawing 1 is a kind of axial cutaway view of basic model thermostat;
But accompanying drawing 2 is a kind of axial cutaway view of temperature-adjusting type thermostat;
Accompanying drawing 3 is often opened the axial cutaway view of normally-closed contact thermostat for band.
Among the figure: 1, fixed contact; 2, moving contact; 3, spring collar; 4, drive rod; 5, memory spring; 6, spring leaf; 7, housing gland; 8, housing; 9, fixed block; 10, slide block; 11, bias spring; 12 adjusting nuts.
As shown in Figure 1, be a kind of thermostat of basic model.Its fixed contact 1 is connected as a single entity with housing 8, moving contact 2 is connected as a single entity with an end of drive rod 4, drive rod 4 is fixed with housing 8 usefulness spring leafs 6, and memory spring 5 usefulness titanium nickel alloy materials are made, and its two parts are not subjected to the constraint of the fixed block 9 of spring collar 3 on the housing 8 and the projection on the drive rod 4.During use, thermostat is placed the temperature control environment, in case when ambient temperature surpassed the transformation temperature of memorial alloy, memory spring 5 was subjected to thermal stretching, promotes drive rod 4 and moves, and makes spring leaf 6 upsets, normally-closed contact disconnects, with the outage source.Because outage, ambient temperature cools down gradually, and when being cooled to the memorial alloy transformation temperature when following, memory spring 5 shrinks voluntarily, and the moving again upset of spring leaf 6 resets, and the normally-closed contact auto-closing is reciprocal thus, the realization temperature control.
As shown in Figure 2, but a kind of thermostat of temp .-regulating type, its feature is, on drive rod 4, be equipped with a governor motion that constitutes by bias spring 11, slide block 10 and the adjusting nut 12 that is connected with bias spring, the both sides of slide block 10 are respectively memory spring 5 and bias spring 11, and slide block can slide on drive rod 4.When giving bias spring afterburning with adjusting nut 12, slip through slide block 10, the power of being executed is passed to memory spring 5, this moment, drive rod 4 did not move, memory spring 5 then produces martensitic phase transformation in advance because of being subjected to stress, make phase point temperature that variation take place, thereby the operating temperature of thermostat moving contact 2 is changed.Because memory spring 5 suffered stress can be arbitrarily adjustable within the specific limits by nut 12, the control temperature of thermostat also is arbitrarily adjustable within the specific limits.
As shown in Figure 3, band is often opened, the thermostat of normally-closed contact, is characterized in, be provided with a fixed contact again at the other end of housing 8, thereby making thermostat often have opens, normally closed two contacts, and more perfect functions is used more extensive.
In a word, the utility model is owing to the intrinsic property that has utilized memorial alloy, and is safe and reliable when making operation, and simple in structure.In addition, because the utility model can have multiple version, make its application very extensive.
