Each pressure switch comprises a contact connected with a wiring lug, and an upper spring leaf mechanism which is connected with the connecting lug and is equipped with a contact. The lower end of the ejector presses against the upper spring leaf mechanism of the pressure switch, and an insulating column is connected between the pressed spring leaf and a spring leaf of the upper spring leaf mechanism of the pressure switch. The improved structure of the pressure stroke switch is characterized in that the front end of the pressed spring leaf is connected with a hook, the pressure plate corresponding to the hook is equipped with a hook buckle, and the hook buckle is a cylindrical object with a stop surface. Compared with the prior art, the improved structure of the pressure stroke switch of the utility model has the advantage of being able to prevent the pressure electric appliance from generating dangerous accidents due to 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.When 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 the connecting ear of pressure switch is connected with control device by electrical signal transmission line according to designing requirement, in the time that 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, when the temperature of pressure cooker declines, 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 causes because of fault after opening circuit under high-temperature condition when occurring, once temperature lower, in the situation that fault is not also got rid of, still path again, 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 provided with hook, on the pressing plate of corresponding hook, be provided with fastener, fastener is above with the column that stops face.
Column is the taper thing that upper end is large, lower end is little.
When 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, make to straighten on compression spring sheet to hook and lean against on the sidewall of column, by regulating the position of pressure experience holder on compression spring sheet to regulate the controlled pressure value of pressure switch, then the connecting ear of pressure switch is connected with control device by electrical signal transmission line according to designing requirement, in the time that 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, when the temperature of pressure cooker declines, 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, make hook along moving and arrive only face on taper beyond the region of objective existence wall, be hooked on the only face of fastener, like this, even if the temperature of pressure cooker lowers because of power-off temperature, compression spring sheet also can not reset, make power turn-on, until people get rid of fault, hook is pushed away to fastener, pressure stroke switch just resumes operation.Because hook leans against on the lateral wall of taper thing, like this, ensured that hook can only move along the lateral wall of taper thing, avoid hook drop on taper thing bottom and can not on move.
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 fixed on screw.Like this, by rotary screw, just can regulate the only height of face 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 reliably that pressure electric appliance from having an accident because of fault.
