Description
Technical field
The present invention relates to a kind of pressure control switch.
Background technology
Two pressure stroke switchs of two pressure stroke switch function are realized disclosed in patent CN200920240616.0 in existing same device, be by all with shake-up shell fragment (from accompanying drawing, should be the compression spring sheet of direct feeling pressure cooker pressure) upper switch, lower switch form, in formation, the shake-up shell fragment of switch, lower switch is connected by touch pole.This kind of two pressure stroke switch, due to needs two shake-up shell fragment, and two touch shell fragment must be connected by touch pole, therefore, volume is large, needing the space taking mobile height, like this, bringing very large inconvenience to answering the design of electrical appliance (as pressure cooker), 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 switch function, can effective space-saving pair of pressure stroke switch.
The present invention realizes like this, comprise pedestal, be fixed on the compression spring sheet on pedestal successively from lower to upper, two pressure switches be arranged side by side, pressing plate, pressure switch includes the contact being connected with connecting ear, be connected with connecting ear and with the upper elastic plate mechanism of contact, be arranged on the holder be arranged side by side on pressing plate, the lower end of two holders leans against on the upper elastic plate mechanism of two pressure switches respectively, all insulated column is connected with between the shell fragment of the upper elastic plate mechanism of compression spring sheet and two pressure switches, the middle part of compression spring sheet end is provided with the pressed sheets perpendicular to compression spring sheet.During work, the present invention is fixed on the bottom in the middle level of pressure cooker, pressed sheets on compression spring sheet heads on the bottom surface in the middle level of pressure cooker, by the controlled pressure value regulating the pressure of two holders on elastic plate mechanism to regulate two pressure switches, then be connected with control device by the connecting ear of electrical signal transmission line by two pressure switches according to designing requirement, because inner tub of pressure cooker is fixed in middle level by pot cover, and side, middle level is fixed on the upper port of shell by the outer rim above middle level, when inner tub of pressure cooker heating boosting, inner bag moves down under the effect of the pressure, by the downward pushing tow middle level of the heating plate of inner bag bottom surface, make to move down bottom middle level, compression spring sheet is promoted by pressed sheets, compression spring sheet is by promoting the shell fragment of the upper elastic plate mechanism of two pressure switches by insulated column, in drive, the contact of elastic plate mechanism leaves the contact being connected with connecting ear, thus power supply is disconnected, pressure cooker no longer heats, when the temperature of pressure cooker declines, after pressure reduces, the shake-up shell fragment of the upper elastic plate mechanism of pressure switch resets, driving its contact to lean against is connected with on the contact of connecting ear, power supply recloses, pressure cooker is reworked, if use according to single pressure switch, two pressure switches work simultaneously can provide double rated current, extend the scope of application of the present invention, if desired during the second Stress control, the control procedure of two pressure switches is identical, just drives the contact of elastic plate mechanism to leave the pressure difference of the contact being connected with connecting ear.Like this, people are when designing, and the pressure switch selecting two kinds of different pressures to control as required, just can realize the control of two kinds of different pressures.Owing to only adopting the pressed sheets of single compression spring sheet and single collection pressure data, therefore, pressure acquisition signal of the present invention is accurate, and meanwhile, height dimension is constant, facilitates the application of user.
Conveniently the pressure of pressure switch regulates, on pressing plate, corresponding two holder places are fixed with nut, the screw rod that has been threaded above of nut, holder upper part pierces in nut, on the upper elastic plate mechanism that the upper end of holder leans against the bottom surface of screw rod, lower end leans against pressure switch.
The present invention compared with the prior art, have can realize two pressure stroke switch function, can the advantage of effectively space-saving, precise control.
