Stick.
Background technique
Thermal Cutoffs is equipped in existing temperature adjustment stick circuit, when product own temperature is excessively high or the temperature controller of main regulation temperature
When failure causes product to reach certain temperature, the Thermal Cutoffs in temperature adjustment stick circuit fuses automatically, keeps product circuit breaking, from
And play the safety protection function for preventing fire.
But although the Thermal Cutoffs in temperature adjustment stick fuses, temperature adjustment stick attaching plug is also in power outlet, such as
Abnormal " Thermal Cutoffs " to a certain extent, to have fused of fruit temperature adjustment stick environment temperature is possible to be connected again, causes safety hidden
Suffer from；And the temperature adjustment stick that Thermal Cutoffs has fused can not be used again, and product need to be taken to specific center after sale or looked for specially
Industry personnel processing, it is time-consuming and laborious.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of hand-reset temperature limiter and uses its temperature adjustment stick.
The present invention protects a kind of hand-reset temperature limiter, including two branches in parallel, respectively low resistance branch and height
Resistance branch；When proper device operation, low resistance branch conducting and with entire circuit communication at a circuit, at load
In energized state；When temperature control goes wrong, and load temperature is more than certain numerical value, the low resistance branch is disconnected, the high electricity
Branch and entire circuit communication are hindered into a circuit, and maintain the off-state of the low resistance branch；It is described after power supply disconnects
The power-off of high resistance branch, the high resistance branch after power-off can not continue to the off-state of the low resistance branch, institute
It states low resistance branch to be connected again, is returned to original state.
Further, the high resistance branch main body uses PTC heater.
Further, the low resistance branch is equipped with fixed contact and moving contact, and the fixed contact is contacted with the moving contact
The then low resistance branch conducting, the fixed contact do not contact the then low resistance branch with the moving contact and disconnect.
Further, whether the fixed contact and the moving contact contact by the arc being located above the PTC heater
Bimetal leaf control, at a circuit, the PTC heater is persistently powered hair for the high resistance branch and entire circuit communication
Heat leads to the arc bi-metal plate deformed, and then struts the moving contact, disconnects the low resistance branch.
Further, the low resistance branch mainly by lug plate, the movable contact spring fixed with the lug plate, be fixed on institute
State moving contact, the fixed contact below the moving contact and the fixed touching plate group connecting with the fixed contact of movable contact spring end
At.
Further, including porcelain seat, the PTC heater are fixed on the porcelain seat, and the lug plate passes through long rivet
It is fixed on porcelain seat one end, the fixed touching plate is fixed on the porcelain seat other end by short rivet.
Further, the PTC heater bottom is equipped with metal clips；It is set between the PTC heater and the porcelain seat
There is metal locking plate.
The present invention also protects the temperature adjustment stick for using hand-reset temperature limiter described in claim 1-8 any one.
Beneficial effects of the present invention: 1. when experiencing overtemperature, can disconnect load automatically, and continues that load is kept to disconnect,
The problem of there is no conducting loads again；2. can restPose automatically after power-off, it is not necessarily to after-sales service, is easy to use.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of hand-reset temperature limiter.
Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.The embodiment of the present invention is
It is provided for the sake of example and description, and is not exhaustively or to limit the invention to disclosed form.Very much
Modifications and variations are obvious for the ordinary skill in the art.Selection and description embodiment are in order to more preferable
Illustrate the principle of the present invention and practical application, and makes those skilled in the art it will be appreciated that the present invention is suitable to design
In the various embodiments with various modifications of special-purpose.
Embodiment 1
The present invention protects a kind of hand-reset temperature limiter, including two branches in parallel, respectively low resistance branch and high resistance
Branch；When proper device operation, the low resistance branch is connected and with entire circuit communication at a circuit, and load is in logical
Electricity condition；When temperature control goes wrong, and load temperature is more than certain numerical value, the low resistance branch is disconnected, the high resistance branch
Road and entire circuit communication maintain the off-state of the low resistance branch at a circuit；After power supply disconnects, the high electricity
Branch power-off is hindered, the high resistance branch after power-off can not continue to the off-state of the low resistance branch, described low
Resistance branch is connected again, is returned to original state.
In the present embodiment, as shown in Figure 1, what the low resistance branch was mainly fixed by lug plate 1, with the lug plate
Movable contact spring 2, the moving contact 3 for being fixed on the movable contact spring end, the fixed contact 4 below the moving contact and touching is determined with described
The fixed touching plate 5 of head connection forms.
Hand-reset temperature limiter is equipped with porcelain seat 12, is fixed on PTC heater 8 on the porcelain seat, the lug plate 1 passes through length
Rivet 11 is fixed on porcelain seat one end, and the fixed touching plate 5 is fixed on the porcelain seat other end, the PTC by short rivet 10
Heater bottom is equipped with metal clips 9；Metal locking plate 7 is equipped between the PTC heater and the porcelain seat.Lug plate 1, long riveting
Nail 11, metal locking plate 7, PTC heater 8, metal clips 9, short rivet 10, fixed touching plate 5 constitute high resistance branch.The dynamic touching
Arc bimetal leaf 6 is equipped between piece and the PTC heater.
Working principle (only by taking temperature adjustment stick as an example):
1. temperature adjustment stick works normally, electric current is connected by lug plate, movable contact spring, moving contact, fixed contact, fixed touching plate and entire circuit
Lead into a circuit, the heater load display energized state of temperature adjustment stick connection at this time, heater persistent fever.
2. when the adjustable temperature controller failure (constantly on) on temperature adjustment stick cannot manage the temperature of load heater, fever
Know from experience persistent fever, when temperature limiter reaches specific temperature, bimetal leaf on temperature limiter is heated reversal deformation, struts dynamic touching
Piece separates moving contact and fixed contact, causes entire circuit to disconnect load heater and stops fever.
3. lug plate, long rivet, metal locking plate, PTC heater, metal clips, short rivet, fixed touching plate and entire electricity at this time
Road forming circuit.PTC heater is high resistance heating part, after energization can persistent fever, the heat generated can allow bimetallic
Piece is constantly in heating status, to keep deforming, allows, fixed contact is always maintained at the state of disconnection, and then ensure that load
Heater will not generate heat again.
4. PTC heater power-off, PTC heater no longer generates heat, at this time bimetal leaf environment when extracting power-line plug
Constant temperature reduce, as low as to a certain degree when, bimetal leaf restore original form, at this time move, fixed contact contact, entire circuit return
Multiple original state, the line plug that plugs in again can work normally.
Obviously, described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, this field and those of ordinary skill in the related art institute without creative labor
The every other embodiment obtained, all should belong to the scope of protection of the invention.
