Abstract
The utility model relates to a pressure displacement control device of an electric pressure cooker, which mainly comprises an outer cooker, a bracket and a sensor. The sensor is arranged at the bottom part of the outer cooker and is fixed by the bracket, and a lead wire is connected at the bottom part of the sensor; the sensor is mainly composed of a coil seat, a coil, a thimble and a magnetic core; the coil is wound on the outer surface of the coil seat, a through hole is arranged in the coil seat, the thimble and the magnetic core are sequentially inserted into the coil seat, the top end of the thimble is in contact with the bottom part of the outer cooker. A spring is arranged at the lower part of the magnetic core, a coil sleeve is sheathed at the outer part of the coil seat, and a fastening piece is arranged at the bottom part of the coil seat. The pressure displacement control device has the following benefits: the pressure displacement control device not only can lead a chip program of a module to control the voltage value (namely control the pressure) by controlling elastic deformation at the bottom part of the outer cooker due to pressure expansion according to the linear relationship between the changing of deformation displacement and the pressure value, but also can adjust the food cooking pressure at will by controlling an input signal of the module, thereby meeting different cooking requirements.
Description
Technical field
The utility model relates generally to the field of the pressure control device of electric pressure cooking saucepan, mainly is a kind of electric pressure cooking saucepan pressure displacement control device.
Background technology
The electric pressure cooking saucepan of existing most producer all adopts the controller of pressure switch at home, and the shortcoming of this mode is that each product can only be set a force value in life cycle, and the consumer can't change this force value.Cooking food can only be by keeping this force value, and solve the cooking method of food by the control time, can't satisfy the demand of diversified food, different mouthfeels.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provide a kind of accurate pressure control, can stepless transformation electric pressure cooking saucepan pressure displacement control device.
The utility model solves the technical scheme that its technical problem adopts: this electric pressure cooking saucepan pressure displacement control device, mainly comprise outer pot, support and sensor, sensor is positioned at outer pot bottom, and fix by support, the bottom of sensor is connected with lead-in wire, sensor is mainly by coil holder, coil, thimble and magnetic core are formed, coil is on the outer surface of coil holder, have through hole in the coil holder, thimble and magnetic core insert in the coil holder successively, and the top of thimble contacts with the bottom of outer pot, and the bottom of magnetic core is provided with spring, the wired snare of the outer cover of coil holder, the bottom of coil holder is provided with securing member.
Be provided with connector between described thimble and the magnetic core.
Described coil holder is provided with two annular grooves, and coil is wrapped in the groove.
Described magnetic core is in the centre of two strand circles.
The effect that the utility model is useful is: external pot bottom produced strain after the utility model expanded by controlled pressure, by the variation of deformation displacement amount and the linear relationship between the force value, the all corresponding certain displacement of the force value of each kPa, and drive moving of magnetic core by the displacement transmission, make the twin coil inductance value produce certain magnitude of voltage.The chip program of control module is controlled the size that magnitude of voltage gets final product controlled pressure.Therefore can carry out regulated at will to food cooking pressure by the input signal of control module, thereby realize different culinary art demands.

Fig. 2 is the exploded perspective view of the utility model structure.
Description of reference numerals: coil cover 1, thimble 2, connector 3, magnetic core 4, spring 5, coil holder 6, coil 7, lead-in wire 8, securing member 9, outer pot 10, support 11, sensor 12, groove 13.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in the figure, this electric pressure cooking saucepan pressure displacement control device, mainly comprise outer pot 10, support 11 and sensor 12, sensor 12 is positioned at outer pot 10 bottoms, and it is fixing by the support 11 of rigid structure, make sensor 12 after last pressure, can not be subjected to displacement change, the bottom of sensor 12 is connected with lead-in wire 8, sensor 12 is mainly by coil holder 6, coil 7, thimble 2 and magnetic core 4 are formed, coil 7 is on the outer surface of coil holder 6, coil holder 6 is provided with two annular grooves 13, coil 7 is wrapped in the groove 13, have through hole in the coil holder 6, thimble 2 and magnetic core 4 insert in the coil holder 6 successively, magnetic core 4 is in the centre of two strand circles 7, the mobile of magnetic core 4 will directly influence the voltage change of the output of inductance coil 7, the top of thimble 2 contacts with the bottom of outer pot 10, and thimble 2 is that metal is made, and has certain resistance to elevated temperatures and rub resistance, owing to fit tightly outer pot 10 bottoms, follow the strain of outer pot 10 and transmit displacement, form the source of moved end, the bottom of magnetic core 4 is provided with spring 5, when the main effect of spring 5 is that outer pot 10 distortion recover, thimble 2 also can recover smoothly, thereby realizes fitting tightly, and prevents that erroneous judgement is disconnected.Be provided with connector 3 between thimble 2 and the magnetic core 4, connector 3 adopts the plastics development, and the displacement of thimble 2 ends is passed to magnetic core 4, prevents that magnetic core 4 from changing variation inductance because of the influence of metal, and has the effect of certain guided way.The wired snare 1 of the outer cover of coil holder 6 is closely fixing between coil holder 6 and the coil cover 1, can not produce change in displacement, and the bottom of coil holder 6 is provided with securing member 9, and 9 pairs of coil holders 6 of securing member and coil 7 are fixed, and form the fixed end.
After pressing on the electric pressure cooking saucepan, pot acted on heat-generating disc and the outer pot 10 in the expansion of interior pot made, thereby make between the interior force value of the strain strain takes place in outer pot 10 bottoms displacement and interior pot certain linear is arranged, according to the slope of linear relationship, calculate the force value of each displacement point.Thereby realize the function of stepless controlled pressure.The utility model, is compared with detected pressure data according to acquiescence or manual input pressure data by the control chip of display module, if reach requirement, just stops the heat-generating disc heating.And move in circles, realize the cooking food of various pressure.
In addition to the implementation, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
