The utility model discloses an electric pressure cooker of automatically controlled pressure, which comprises a controlling device, a cooker body and a cooker cover, wherein the cooker body and the cooker cover are mutually buckled; the cooker cover is arranged on the cooker body; a pressure switch is fixed on the cooker body; the bottom end of the cooker cover is provided with a touching arm which stretches to the pressure switch; the space between the cooker cover and the cooker body is also provided with a pressure spring; the pressure switch is electrically connected with the controlling device. Consequently, the utility model has the advantages of simple structure, low cost and convenient installation and maintenance.
Description
Technical field
The utility model relates to automatic pressure-controlled electric pressure cooking saucepan field.
Background technology
At present, electric pressure cooking saucepan is easy to use with it, saves the energy, and be subjected to people's welcome deeply, and for pressure cooker, its pressure control is vital, it is related to the safety in utilization of pressure cooker, and existing electric pressure cooking saucepan can be divided into Temperature Control Type and pressure-controlled by control mode.Pressure-controlled auto-electronic pressure cooker mostly be between heat-generating disc and stay-warm case, be provided with realize in pot with stay-warm case between elastic supporting mechanisms such as the corrugated plating that is connected of elasticity or disk spring, by these elastic supporting mechanisms the pressure that produces in the interior pot is delivered to heat-generating disc, heat-generating disc extruding elastic supporting mechanism, make between heat-generating disc and the stay-warm case and produce relative displacement, thereby make the pressure control device action that is installed between heat-generating disc bottom stay-warm case and the shell, with the connecting and disconnecting of control heat-generating disc, reach the purpose of control inner pot pressure.But there is following shortcoming in it: 1) these elastic supporting mechanism complex structures such as while corrugated plating or disk spring, and processing and installation are not easy, and production cost is higher, and influence is promoted the use of.2) pressure control device is installed on its installation and maintenance inconvenience between heat-generating disc bottom stay-warm case and the shell.
The utility model content
The purpose of this utility model is to solve above-mentioned shortcoming, and provides a kind of simple in structure, and at the bottom of the cost, installation and maintenance are auto-electronic pressure cooker easily.
The purpose of this utility model is to realize like this, a kind of automatic pressure-controlled electric pressure cooking saucepan, comprise a pot body, pot cover and control device, pot cover is located on pot body, fix a pressure switch on the described pot body, the pot cover bottom is provided with the shake-up arm that stretches to pressure switch, also is provided with compression spring between described shake-up arm and the pot body, and pressure switch is electrically connected with control device.
Described pot of body comprises outer pot and shell, and clamping connection has ring between pot and the shell, and pressure switch is fixed in the bottom of middle ring, and described middle ring has the through hole that passes for lever arm, and the shake-up arm passes through hole and pressure switch is joined.
Described lever arm is provided with a fixture block, is covered with a pressure spring on the lever arm between through hole and fixture block.
Described pot cover comprises inner pot cover and is fixed in the cover of inner pot cover upper surface that compression spring is placed between inner pot cover and the outer pot.
Described pressure switch is normally closed pressure switch.1), owing to fix a pressure switch on the pot of the present utility model body the beneficial effects of the utility model are:, the pot cover bottom is provided with the shake-up arm that stretches to pressure switch, also be provided with compression spring between described shake-up arm and the pot body, pressure switch is electrically connected with control device, this is simple in structure, reduces production costs.2), since pressure switch be fixed in the bottom of ring, described in ring have the through hole that passes for lever arm, touch arm and pass through hole, thereby its installation and maintenance are got up conveniently with pressure switch is joined.

The specific embodiment
As shown in Figures 1 to 3, a kind of automatic pressure-controlled electric pressure cooking saucepan, comprise control device 3, the pot body 1 and pot cover 2, the pot cover 2 that fasten mutually are located on pot body 1, fix a pressure switch 4 on the described pot body 1, pot cover 2 bottoms are provided with the shake-up arm 5 that stretches to pressure switch 4, also are provided with compression spring 6 between 2 pots of bodies 1 of described pot cover, and pressure switch 4 is electrically connected with control device 3.Pot body 1 comprises, clamping connection has and encircles 7 in one between outer pot 101 and the shell 102, interior pot 101 and outer pot 102, the bottom of ring 7 during pressure switch 4 is fixed in, described in ring 7 have the through hole 701 that passes for lever arm 5, touch that arm 5 passes through hole 701 and pressure switch 4 is joined.Lever arm 5 is provided with a fixture block 501, is socketed with a pressure spring 8 on the lever arm 5 that through hole 701 and fixture block are 501.Pot cover 2 comprises inner pot cover 201 and is fixed in the cover 202 of inner pot cover upper surface that compression spring 6 is placed between inner pot cover 201 and the outer pot 101.Described pressure switch 4 is normally closed pressure switches.
Operation principle: during cooking food, the heat-generating disc heating, air pressure in pot courage is strengthened, the air pressure that it produced promotes the pot cover body and moves upward, when the pot internal gas pressure reached setting value, the pot cover body was lifted, and the inner pot cover in the pot cover contacts with spring at this moment, because the elastic force of spring increases pot cover body weight power, slow resistance pot cover body rises.When air pressure continued to raise, spring was compressed, and the pull bar of pot cover body drive simultaneously continues to rise.And the pull bar that is connected on the pot cover is lived in to promote along with the rising of pot cover, spurs pressure switch simultaneously, the pressure switch normally-closed contact is drawn back, the circuit of cutting off the electricity supply.Heat-generating disc stops heating, and it is safe in utilization to guarantee that do not have pressure rises this moment again.Return mutually, after heating stops, air pressure in the pot courage descends, be subjected to the elastic force of spring and the deadweight of pot cover body that the pot cover body is moved downward, pull bar moves downward simultaneously, this moment pressure switch contact reset, power connection, heat-generating disc begins heating, a pot internal gas pressure begins again to rise, as repeating above do action.
