As shown in fig. 1 to 4, the electric pressure cooker of the present embodiment includes a cooker body 10, a cooker cover 20, an exhaust pipe 30, a pressure limiting valve 40, and a switching device. Wherein the pan body 10 is used for containing food to be cooked. The pot cover 20 is provided on the pot body 10. The exhaust pipe 30 and the pressure limiting valve 40, the exhaust pipe 30 is arranged on the pot cover 20 and communicated with the interior of the pot body 10. The pressure limiting valve 40 is provided on the exhaust pipe 30, and a first magnetic member 41 is provided on the pressure limiting valve 40. The switching device is arranged in the pot cover 20 and is movably arranged relative to the pressure limiting valve 40, a plurality of second magnetic pieces 60 with different magnetism are arranged on the switching device, and the second magnetic pieces 60 are matched with the first magnetic pieces 41 and apply magnetic force towards the pressure limiting valve 40. The switching device has a plurality of switching positions, and the switching device changes the magnetic force applied to the pressure limiting valve 40 when moving between the different switching positions.
By applying the technical scheme of the embodiment, the switching device is arranged in the electric pressure cooker. The switching means may engage a second, different magnetic member 60 with the first magnetic member 41, thereby applying a different magnetic force to the pressure limiting valve 40. The structure does not need to control the magnetic force in an up-and-down adjusting mode, thereby reducing the requirements on the manufacturing precision and the assembly precision of the electric pressure cooker. Therefore, the technical scheme of the embodiment solves the problem that the magnetic driving structure of the pressure limiting valve of the electric pressure cooker in the prior art needs higher manufacturing precision and installation precision.
Preferably, in the technical solution of the present embodiment, when the switching device is located at the switching position, one second magnetic element 60 of the plurality of second magnetic elements 60 is disposed corresponding to the first magnetic element 41. Specifically, since the plurality of second magnetic members 60 each have different magnetic forces, when the switching device is in a certain position, a certain one of the plurality of second magnetic members 60 is disposed corresponding to the first magnetic member 41 and applies a corresponding magnetic force. When the switching device is at different positions, the second magnetic members 60 exert different magnetic forces on the first magnetic member 41, so as to exert different acting forces on the pressure limiting valve 40, thereby achieving the effect of controlling the exhaust pressure of the pressure limiting valve 40.
It should be noted that the above "different magnetic forces" have three cases: first, the magnetic field magnitude and the magnetic field direction of the different second magnetic pieces 60 are different; second, the magnetic fields of the different second magnetic pieces 60 are different in magnitude, but the magnetic fields are the same in direction; third, the second, different magnetic member 60 has the same magnitude but different direction of the magnetic field.
Preferably, in the technical solution of the present embodiment, a plurality of second magnetic members 60 are disposed at intervals on the switching device. The above structure enables the second magnetic member 60 different from the first magnetic member 41 to be disposed correspondingly when the switching device is moving.
As shown in fig. 4 to 6, in the technical solution of the present embodiment, the switching device includes a slider 51, the slider 51 is slidably disposed below the pressure limiting valve 40, and a plurality of second magnetic members 60 are disposed at intervals along the length direction of the slider 51. Preferably, the slider 51 slides in the horizontal direction, thereby preventing an influence of an error in the vertical direction on the magnetic force between the first magnetic member 41 and the second magnetic member 60.
As shown in fig. 6, in the technical solution of the present embodiment, a sliding groove 52 is provided on a sliding block 51, the sliding block 51 is sleeved outside the exhaust pipe 30 through the sliding groove 52, and the sliding block 51 is located below the pressure limiting valve 40. The above structure makes the assembly of the slider 51 simple and facilitates the fixation of the slider 51. Of course, the slider 51 may be located above the pressure limiting valve.
Preferably, the chute 52 is an elongated slot. The distance between the opposite side walls of the chute 52 is adapted to the diameter of the exhaust pipe 30 in a direction perpendicular to the extension of the chute 52. The above structure can reduce the rattling of the slider 51 with respect to the exhaust pipe 30, and further improve the control accuracy between the first magnetic member 41 and the second magnetic member 60.
Preferably, the plurality of second magnetic members 60 are disposed at intervals along the extending direction of the chute 52. Specifically, when the slider 51 slides in the horizontal direction, the plurality of second magnetic members 60 are engaged with the first magnetic members 41, respectively.
As shown in fig. 2 and 3, in the technical solution of the present embodiment, the first magnetic member 41 is a ring magnet, and the slider 51 includes a first rod section 511 and a second rod section 512, and a third rod section 513 and a fourth rod section 514. Wherein the first pole segment 511 and the second pole segment 512 are oppositely disposed, two ends of the third pole segment 513 are respectively connected between the first pole segment 511 and the second pole segment 512, two ends of the fourth pole segment 514 are respectively connected between the first pole segment 511 and the second pole segment 512, and the third pole segment 513 and the fourth pole segment 514 are oppositely disposed. The first pole section 511, the second pole section 512, the third pole section 513 and the fourth pole section 514 enclose a chute. The second magnetic member 60 includes a first magnetic block 61 and a second magnetic block 62, the first magnetic block 61 and the second magnetic block 62 have the same magnetic properties, the first magnetic block 61 and the second magnetic block 62 are respectively disposed on the first pole section 511 and the second pole section 512, and the first magnetic block 61 and the second magnetic block 62 are disposed opposite to each other. Specifically, each of the second magnetic pieces 60 includes one first magnetic block 61 and one second magnetic block 62. The above structure enables the first magnetic member 41 to apply a magnetic force vertically upward or vertically downward to the first magnetic block 61 and the second magnetic block 62, thereby preventing the pressure limiting valve 40 from being deflected, and thus preventing the exhaust pipe 30 from leaking.
Preferably, the second magnetic member 60 applies a magnetic force toward the pot 10 or a magnetic force away from the pot 10 to the first magnetic member 41. Specifically, when the second magnetic member 60 applies a magnetic force toward the direction of the pot body 10 to the first magnetic member 41, the second magnetic member 60 causes the pressure limiting valve 40 to press down against the exhaust pipe 30, thereby increasing the exhaust pressure. When the second magnetic member 60 applies a magnetic force to the first magnetic member 41 in a direction away from the pot 10. The second magnetic member 60 lifts the pressure limiting valve 40 upward, thereby reducing the exhaust pressure.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
