Description
Technical field:
The present invention relates to a kind of pressure control switch.
Background technology:
Existing pressure stroke switch generally comprise pedestal, be fixed on from lower to upper successively on pedestal with pressure experience
The compression spring piece of holder, more than one pressure switch pressing plate with holder corresponding with corresponding pressure switch, pressure
Switch include be connected with connecting ear contact, be connected with connecting ear and with contact upper elastic plate mechanism, the lower end of holder
Lean against on the upper elastic plate mechanism of pressure switch, between the shell fragment of upper elastic plate mechanism of compression spring piece and pressure switch, be connected with insulation
Post.During work, this pressure stroke switch is fixed on the bottom in the middle level of pressure cooker, the pressure experience holder top of compression spring piece
The bottom surface in the middle level of pressure cooker, adjust pressure switch by adjusting position in compression spring piece for the pressure experience holder
Then the connecting ear of pressure switch is connected with control device by electrical signal transmission line by control pressure value according to design requirement,
When inner tub of pressure cooker heating boosting, inner bag moves down under the effect of the pressure, by the downward pushing tow of the heating dish of inner bag bottom surface
Layer, makes middle level bottom move down, and moves compression spring piece by pressure experience holder pushing tow, and compression spring piece is by insulation
Post promotes the shell fragment of the upper elastic plate mechanism of pressure switch, and in drive, the contact of elastic plate mechanism leaves the contact being connected with connecting ear,
So that power supply disconnects, pressure cooker is no longer heat up, when the temperature drop of pressure cooker, after reduced pressure, the upper shell fragment of pressure switch
The shake-up shell fragment of mechanism resets, and drives its contact to lean against on the contact being connected with connecting ear, power supply recloses, and pressure cooker is again
Work.Pressure stroke switch when occur hindering for some reason and after lead to the open circuit under high-temperature condition, once temperature lowers, in fault also
In the case of not excluding, still can path again, thus being susceptible to peril.
Content of the invention:
The goal of the invention of the present invention is to provide a kind of pressure that can prevent pressure electric appliance from hindering for some reason and have an accident
Travel switch.
The present invention be achieved in that including pedestal, be fixed on from lower to upper successively on pedestal with pressure experience top
The compression spring piece of son, more than one pressure switch pressing plate with holder corresponding with corresponding pressure switch, pressure is opened
Close include be connected with connecting ear contact, be connected with connecting ear and with contact upper elastic plate mechanism, the lower end of holder is leaned on
On the upper elastic plate mechanism of pressure switch, between the shell fragment of upper elastic plate mechanism of compression spring piece and pressure switch, it is connected with insulation
Post, it is particular in that compression spring piece front end is connected with hook, and the pressing plate of corresponding hook is provided with fastener.
During work, this pressure stroke switch is fixed on the bottom in the middle level of pressure cooker, the pressure experience of compression spring piece
Holder heads on the bottom surface in the middle level of pressure cooker, adjusts pressure by adjusting position in compression spring piece for the pressure experience holder
The control pressure value of switch, then passes through electrical signal transmission line by the connecting ear of pressure switch and control device according to design requirement
It is connected, when inner tub of pressure cooker heating boosting, inner bag moves down under the effect of the pressure, is pushed up downwards by the heating dish of inner bag bottom surface
Push away middle level, so that middle level bottom is moved down, compression spring piece is moved by pressure experience holder pushing tow, compression spring piece is passed through
Insulated column promotes the shell fragment of the upper elastic plate mechanism of pressure switch, and in drive, the contact of elastic plate mechanism leaves and is connected with touching of connecting ear
Head, so that power supply disconnects, pressure cooker is no longer heat up, when the temperature drop of pressure cooker, after reduced pressure, the upper bullet of pressure switch
The shake-up shell fragment of piece mechanism resets, and drives its contact to lean against on the contact being connected with connecting ear, power supply recloses, pressure cooker weight
New work；Lead to abnormal heating when electrical equipment breaks down, when making the safety value that the pressure of pressure cooker reaches setting, pressure cooker
Middle level bottom moves down, and moves compression spring piece by pressure experience holder pushing tow, compression spring piece is by pushing away by insulated column
Dynamic pressure switch upper elastic plate mechanism shell fragment, so that hook is hooked on fastener, so, even if the temperature of pressure cooker because of power-off temperature
Lower, compression spring piece also will not reset, so that power supply is turned on, until people, by failture evacuation, hook are pushed away fastener, pressure row
Cheng Kaiguan just resumes operation.
Here, fastener governor motion is provided with pressing plate, fastener governor motion includes screw, the rotation being arranged on pressing plate
It is connected on the screw in screw, fastener is arranged on screw.So, the height of fastener can by rotary screw, just be adjusted, thus setting
Fixed barrier for some reason and safe pressure during power-off.
Compared with the prior art the present invention, has the advantages that to prevent pressure electric appliance from hindering for some reason and having an accident.
