Description
Technical field
The present invention relates to a kind of pressure control switch.
Background technology
The two pressure stroke switches such as the patent CN200920240616.0 that realize two pressure stroke switching functions in the existing same device are disclosed; Be (to see from accompanying drawing by all having the shake-up shell fragment; Should be the compression spring sheet of directly experiencing pressure cooker pressure) last switch, down switch constitutes, switch formations on, the shake-up shell fragment of switch passes through the touch pole connection down.The two pressure stroke switches of this kind, owing to need two to touch shell fragment, and; Two touch shell fragment must connect through touch pole, and therefore, volume is big; Need take the space of moving height, like this, answered the design of electrical appliance (like pressure cooker) to bring very big inconvenience; And, can not effectively reduce the volume of answering electrical appliance.
Summary of the invention
Goal of the invention of the present invention be to provide a kind of can realize two pressure stroke switching functions, can effectively space-saving pair of pressure stroke switch.
The present invention realizes like this; Comprise pedestal, be fixed on the compression spring sheet that has the pressure experience holder, downforce switch, center platen, upward pressure switch, pressing plate on the pedestal from lower to upper successively; The downforce switch includes the contact that is connected with connecting ear, that be connected with connecting ear and last shell fragment that have contact mechanism, be arranged on the holder on the center platen; The lower end of holder leans against in the last shell fragment mechanism of downforce switch; The upward pressure switch comprises the contact that is connected with connecting ear, that be connected with connecting ear and last shell fragment that have contact mechanism, be arranged on the adjusting holder on the pressing plate; The lower end of regulating holder leans against in the last shell fragment mechanism of upward pressure switch, between the shell fragment of the last shell fragment mechanism of compression spring sheet and downforce switch, all be connected with insulated column between the shell fragment of the last shell fragment mechanism of the shell fragment of the last shell fragment mechanism of downforce switch and upward pressure switch.During work, the present invention is fixed on the bottom in the middle level of pressure cooker, the pressure experience holder of compression spring sheet heads on the bottom surface in middle level; Through regulating the controlled pressure value that the downforce switch is regulated in the position of pressure experience holder on the compression spring sheet, the controlled pressure value through the upward pressure switch is regulated in the position of adjusting holder on pressing plate of regulating on the pressing plate links to each other with control device through the connecting ear of electrical signal transmission line with upward pressure switch, downforce switch according to designing requirement then; Because the pressure cooker inner bag is fixed in the middle level through pot cover, and the middle level side is fixed on the port of shell through the outer rim above the middle level, when the heating of pressure cooker inner bag is boosted; Inner bag moves down under the effect of pressure, through the downward pushing tow of the heating plate of inner bag bottom surface middle level, the bottom, middle level is moved down; Through the moving compression spring sheet of pressure experience holder pushing tow, the shell fragment of the last shell fragment mechanism of compression spring sheet through promoting the downforce switch through insulated column, the contact of shell fragment mechanism leaves the contact that is connected with connecting ear in the drive; Thereby power supply is broken off, and pressure cooker no longer heats, when the temperature decline of pressure cooker; After pressure reduces; The shake-up shell fragment of the last shell fragment mechanism of downforce switch resets, and drives its contact and leans against on the contact that is connected with connecting ear, and power supply recloses; Pressure cooker is reworked; If when needing second kind of pressure control, the control procedure of upward pressure switch is identical with the course of work of downforce switch, the contact that just drives shell fragment mechanism leaves the pressure difference of the contact that is connected with connecting ear.Like this, people select the pressure switch of two kinds of different pressures controls as required when design, just can realize the control of two kinds of different pressures.Owing to only adopt single compression spring sheet, therefore, height dimension of the present invention is less, has made things convenient for user's application.
The pressure of downforce switch is regulated for ease, on the compression spring sheet, is fixed with nut, and the cross-under of pressure experience holder screw thread is on nut.
The pressure of upward pressure switch is regulated for ease; On pressing plate, be fixed with nut; The screw rod that has been threaded above the nut is regulated holder top and is pierced in the nut, and bottom surface, the lower end that the upper end of regulating holder leans against screw rod leans against in the last shell fragment mechanism of upward pressure switch.
The present invention compared with present technology, have can realize two pressure stroke switching functions, can effective space-saving advantage.
