Compared with the prior art, the pressure travel switch can prevent a pressure electric appliance from having dangerous accidents caused by faults.
Description
Technical field:
The utility model relates to a kind of pressure control switch.
Background technology:
Existing pressure stroke switch generally comprises pedestal, is fixed on from lower to upper the compression spring sheet with pressure experience holder on pedestal, more than one pressure switch, the pressing plate with holder corresponding with corresponding pressure switch successively, pressure switch include be connected with connecting ear contact, be connected with connecting ear and with the upper elastic plate mechanism of contact, the lower end of holder leans against on the upper elastic plate mechanism of pressure switch, between the shell fragment of the upper elastic plate mechanism of compression spring sheet and pressure switch, is connected with insulated column.During work, this pressure stroke switch is fixed on to the bottom in the middle level of pressure cooker, the pressure experience holder of compression spring sheet heads on the bottom surface in the middle level of pressure cooker, by regulating the position of pressure experience holder on compression spring sheet to regulate the controlled pressure value of pressure switch, then according to designing requirement, by electrical signal transmission line, the connecting ear of pressure switch is connected with control device, when inner tub of pressure cooker heating is boosted, inner bag moves down under the effect of pressure, by the downward pushing tow of the heating plate middle level of inner bag bottom surface, bottom, middle level is moved down, by the moving compression spring sheet of pressure experience holder pushing tow, compression spring sheet is by promoting the shell fragment of the upper elastic plate mechanism of pressure switch by insulated column, in drive, the contact of elastic plate mechanism leaves the contact that is connected with connecting ear, thereby power supply is disconnected, pressure cooker no longer heats, temperature decline when pressure cooker, after pressure decreased, the shake-up shell fragment of the upper elastic plate mechanism of pressure switch resets, drive its contact to lean against on the contact that is connected with connecting ear, power supply recloses, pressure cooker is reworked.Pressure stroke switch after there is causing because of fault opening circuit under high-temperature condition, once temperature lower, in the situation that fault is not also got rid of, path again still, thereby easily have an accident.
Summary of the invention:
Goal of the invention of the present utility model is to provide a kind of pressure stroke switch that can prevent that pressure electric appliance from having an accident because of fault.
The utility model is to realize like this, comprise pedestal, be fixed on from lower to upper successively the compression spring sheet with pressure experience holder on pedestal, more than one pressure switch, the pressing plate with holder corresponding with corresponding pressure switch, pressure switch includes the contact that is connected with connecting ear, be connected with connecting ear and with the upper elastic plate mechanism of contact, the lower end of holder leans against on the upper elastic plate mechanism of pressure switch, between the shell fragment of the upper elastic plate mechanism of compression spring sheet and pressure switch, be connected with insulated column, its special feature is that compression spring sheet front end is connected with hook, on the pressing plate of corresponding hook, be provided with fastener.
During work, this pressure stroke switch is fixed on to the bottom in the middle level of pressure cooker, the pressure experience holder of compression spring sheet heads on the bottom surface in the middle level of pressure cooker, by regulating the position of pressure experience holder on compression spring sheet to regulate the controlled pressure value of pressure switch, then according to designing requirement, by electrical signal transmission line, the connecting ear of pressure switch is connected with control device, when inner tub of pressure cooker heating is boosted, inner bag moves down under the effect of pressure, by the downward pushing tow of the heating plate middle level of inner bag bottom surface, bottom, middle level is moved down, by the moving compression spring sheet of pressure experience holder pushing tow, compression spring sheet is by promoting the shell fragment of the upper elastic plate mechanism of pressure switch by insulated column, in drive, the contact of elastic plate mechanism leaves the contact that is connected with connecting ear, thereby power supply is disconnected, pressure cooker no longer heats, temperature decline when pressure cooker, after pressure decreased, the shake-up shell fragment of the upper elastic plate mechanism of pressure switch resets, drive its contact to lean against on the contact that is connected with connecting ear, power supply recloses, pressure cooker is reworked, when breaking down, electrical equipment causes undesired heating, while making the pressure of pressure cooker reach the safety value of setting, the bottom, middle level of pressure cooker moves down, by the moving compression spring sheet of pressure experience holder pushing tow, compression spring sheet is by promoting the shell fragment of the upper elastic plate mechanism of pressure switch by insulated column, hook is hooked on fastener, like this, even if the temperature of pressure cooker lowers because of power-off temperature, compression spring sheet can not reset yet, and makes power turn-on, until people get rid of fault, hook is pushed away to fastener, and pressure stroke switch just resumes operation.
Here, be provided with fastener governor motion on pressing plate, fastener governor motion comprises the screw that is arranged on pressing plate, is screwed in the screw in screw, and fastener is arranged on screw.Like this, by rotary screw, just can regulate the height of fastener, thus the safe pressure while setting because of fault power-off.
Compared with the prior art the utility model, has advantages of and can prevent that pressure electric appliance from having an accident because of fault.
