The invention discloses a temperature-sensitive magnetic temperature switch, which comprises a fixed contact and a movable contact tightly matched with the fixed contact, wherein the movable contact is connected with a push rod; it still includes first permanent magnet piece, second permanent magnet piece and is located the temperature sensitive magnetic sheet between first permanent magnet piece and the second permanent magnet piece and first permanent magnet piece is even as an organic whole with the temperature sensitive magnetic sheet, first permanent magnet piece and second permanent magnet piece are axial magnetization and their magnetic pole in opposite directions and are the form of pushing away and repel and arrange, the push rod is connected with second permanent magnet piece and makes the push rod drive under the drive of this second permanent magnet piece the movable contact switches on or breaks off with the stationary contact. The invention has the advantages of good temperature sensing effect, reliable action and the like.
Description
Technical field
The present invention relates to a kind of temperature switch, more particularly, relate to a kind of temperature sensitive magnetic temperature switch.
Background technology
At present, market has all kinds of temperature switch, but conventional temperature switch temperature-sensitive poor effect, action is unreliable.Not yet commercially see good temperature sensing effect at present, the temperature switch of reliable in action.
Summary of the invention
Technical problem to be solved by this invention is to provide the temperature sensitive magnetic temperature switch of a kind of good temperature sensing effect, reliable in action.
In order to solve the problems of the technologies described above, present invention employs following technical scheme:
A kind of temperature sensitive magnetic temperature switch, it comprises fixed contact and the moving contact with fixed contact close-fitting, and described moving contact is connected with a push rod; It also comprises the first permanent magnet sheet, the second permanent magnet sheet and the temperature sensitive magnetic sheet between the first permanent magnet sheet and the second permanent magnet sheet and the first permanent magnet sheet and temperature sensitive magnetic sheet are connected as a single entity, described first permanent magnet sheet and the second permanent magnet sheet are axial magnetized and their magnetic pole arranges in opposite directions and in repulsion shape, and described push rod is connected with the second permanent magnet sheet and under the drive of this second permanent magnet sheet, makes push rod drive described moving contact and fixed contact connect or disconnect.
The present invention is owing to have employed said structure, temperature sensitive magnetic sheet is as temperature sensitive magnetic conductor, its permeability before and after Curie point reaches the change of tens times, therefore the present invention is by utilizing the above-mentioned characteristic of temperature sensitive magnetic conductor, the body that coincides of the first permanent magnet sheet, temperature sensitive magnetic sheet, the second permanent magnet sheet three magnetic monomers is formed one by push rod and moving contact, fixed contact combined loop and forms temperature sensitive magnetic temperature switch, thus moving contact can be realized and fixed contact is connected or disconnects, good temperature sensing effect of the present invention, its reliable in action opened and close.
After the detailed description of reading embodiments of the present invention by reference to the accompanying drawings, the features and advantages of the invention will become clearly.
Accompanying drawing explanation
Fig. 1 is embodiments of the present invention schematic diagrames in the off state; And
Fig. 2 is embodiments of the present invention schematic diagrames in an on state.
In figure: 1 is fixed contact, 2 is moving contact, and 3 is push rod, and 4 is the first permanent magnet sheet, and 5 is temperature sensitive magnetic sheet, and 6 is the second permanent magnet sheet.
Embodiment
The present invention is further detailed explanation in one embodiment below, but should illustrate, protection scope of the present invention is not limited only to this.
Consult Fig. 1 and Fig. 2, a kind of temperature sensitive magnetic temperature switch, it comprises fixed contact 1 and the moving contact 2 with fixed contact 1 close-fitting, and moving contact 2 is connected with a push rod 3.In the present embodiment, it also comprises the first permanent magnet sheet 4, second permanent magnet sheet 6 and the temperature sensitive magnetic sheet 5 between the first permanent magnet sheet 4 and the second permanent magnet sheet 6 and the first permanent magnet sheet 4 are connected as a single entity with temperature sensitive magnetic sheet 5, first permanent magnet sheet 4 and the second permanent magnet sheet 6 are axial magnetized and their magnetic pole arranges in opposite directions and in repulsion shape, namely the first permanent magnet sheet 4 is like pole with the relative temperature sensitive magnetic sheet 5 of the second permanent magnet sheet 6, push rod 3 is connected with the second permanent magnet sheet 6 and under the drive of this second permanent magnet sheet 6, makes push rod 3 drive described moving contact 2 connect with fixed contact 1 or disconnect.
When present embodiment specifically uses, such as, the thickness that can set temperature sensitive magnetic sheet 5 is t millimeter, the distance of separation of fixed contact 1 and moving contact 2 is s millimeter, implementation capacity is f, and the magnetic field of the first permanent magnet sheet 4, second permanent magnet sheet 6 is in repulsion state, along repulsive force inverse direction impose >=power of f time, if the distance >=t+s millimeter between the first permanent magnet sheet 4, second permanent magnet sheet 6, can form following functional status:
(1) when ambient temperature is normal temperature state, the first permanent magnet sheet 4, second permanent magnet sheet 6 is adsorbed on temperature sensitive magnetic sheet 5, and moving contact 2 and fixed contact 1 are connected, and now, loop, sound contact is in on-state (static state).
(2) after variation of ambient temperature exceedes the Curie point of temperature sensitive magnetic sheet 5, the permeability of temperature sensitive magnetic sheet 5 sharply declines, because the like pole of the first permanent magnet sheet 4, second permanent magnet sheet 6 repels in opposite directions, and be connected as a single entity with temperature sensitive magnetic sheet 5 due to the first permanent magnet sheet 4 on the left side, so the second permanent magnet sheet 6 on the right is by repulsion, related push rod 3 moves, thus moving contact 2 and fixed contact 1 are disconnected, namely loop, sound contact is in off-state (dynamically).
(3) after below the Curie point that variation of ambient temperature is returned to temperature sensitive magnetic sheet 5, the permeability of temperature sensitive magnetic sheet 5 is sharply gone up, by adsorbing, related push rod 3 is moved by absorption the second permanent magnet sheet 6 on the right, thus moving contact 2 is moved and finally makes to connect fixed contact 1 and moving contact 2 is connected, i.e. loop, sound contact but also be in on-state, return to initial condition, complete an action cycle.Accordingly, corresponding temperature sensitive magnetic control temperature detect switch (TDS) class device can be formed.
Although describe embodiments of the present invention by reference to the accompanying drawings; but those skilled in the art can make various distortion or amendment within the scope of the appended claims; as long as be no more than the protection range described by claim of the present invention, all should within protection scope of the present invention.
