As shown in fig. 1 and 2, the electric pressure cooker of the present embodiment includes a cooker body, a pressure limiting valve 30 of a cooker cover 10, and a guide structure 40. Wherein, the pot body is used for holding the food to be cooked. The pot cover 10 is arranged on the pot body, and the pot cover 10 comprises a pot cover main body 11 and an inner pot cover 12 arranged on the pot cover main body 11. The driving part 20 is arranged in the cooker cover main body 11, the pressure limiting valve 30 is arranged on the inner cooker cover 12, and the pushing handle 31 is arranged on the outer side wall of the pressure limiting valve 30. When the lid is in the open state, the driving member 20 pushes the push handle 31 and exhausts the pressure limiting valve 30. The guiding structure 40 is disposed between the lid body 11 and the pressure limiting valve 30, and the guiding structure 40 enables the pressure limiting valve 30 to rotate around its axis and enables the push handle 31 to avoid the driving member 20 during the process of mounting the inner lid 12 on the lid body 11, the pressure limiting valve 30 is reset and enables the driving member 20 to cooperate with the push handle 31.
With the technical solution of this embodiment, the guiding structure 40 rotates the pressure limiting valve 30 and causes the push handle 31 to avoid the driving member 20 during the process of installing the inner pot cover. When the inner pot cover 12 is mounted on the pot cover main body 11, the pressure limiting valve 30 is reset and enables the push handle 31 to be matched with the driving piece 20, so that the driving piece 20 can normally push the push handle 31. The structure realizes that the push handle 31 of the pressure limiting valve 30 is not contacted with the push rod 21 in the process of installing the inner pot cover 12, and further prevents friction between the push handle 31 of the pressure limiting valve 30 and the push rod, so that the technical scheme of the embodiment solves the problem that the push rod of the electromagnetic valve and the push handle of the pressure limiting valve are easy to generate friction interference when the inner pot cover is installed or detached in the uncapping state of the electric pressure cooker in the prior art.
As shown in fig. 1 to 4, in the technical solution of the present embodiment, the guide structure 40 includes a guide block 41 and a guide post 42. Wherein the guide block 41 is provided on a side wall of the pressure limiting valve 30. The guide post 42 is disposed in the lid body 11 and extends toward the pressure limiting valve 30, and the guide block 41 and/or the guide post 42 are provided with a guide inclined surface 43, and when the inner lid 12 is mounted on the lid body 11, the guide inclined surface 43 drives the pressure limiting valve 30 to rotate about its axis. Specifically, when the inner pot cover 12 is mounted on the pot cover body 11 from bottom to top, the guide block 41 and the guide post 42 are abutted and matched, so that the pressure limiting valve 30 is driven to rotate. Meanwhile, by providing the guide inclined surface 43, on the one hand, the pressure limiting valve 30 can be rotated in a predetermined direction, and on the other hand, the rotation of the pressure limiting valve 30 can be smoother, and the mutual locking between the mechanisms can be prevented.
As shown in fig. 1 to 4, in the technical solution of the present embodiment, the surface of the guide post 42 facing the guide block 41 is provided with a receiving recess 421, and when the inner lid 12 is mounted on the lid body 11, the guide block 41 is inserted into the receiving recess 421 and engages the push handle 31 with the driving member 20. Specifically, during the process of installing the inner lid 12, as can be seen from fig. 2 and 4, the pressure limiting valve 30 swings toward the right, and the push handle 31 and the driving member 20 are separated from each other. When the inner lid 12 is mounted, the pressure limiting valve 30 swings back and falls down along the left side by gravity, and when the guide block 41 is inserted into the accommodating recess 421, the push handle 31 and the driving piece 20 come into contact. The accommodating recess 421 provides a backswing space for the guide block 41, and the accommodating recess 421 can limit the backswing position of the pressure limiting valve 30.
As shown in fig. 5, in the technical solution of the present embodiment, a guide slope 43 is provided on a surface of the guide block 41 facing the guide post 42, and the guide slope 43 includes a first guide slope 431 and a second guide slope 432 that are angled with respect to each other. The first guide slope 431 is located above the second guide slope 432. In the process of mounting the inner pot cover 12 on the pot cover main body 11, the first guide inclined surface 431 abuts against the lower surface of the guide post 42 and drives the pressure limiting valve 30 to rotate, and when the inner pot cover 12 is dismounted from the pot cover main body 11, the second guide inclined surface 432 abuts against the inner surface of the accommodating recess portion 421 and drives the guide block 41 to rotate. Specifically, the guide block 41 is "<", that is, the left side surface of the guide block 41 forms the above-described first guide slope 431 and second guide slope 432. The first guide slope 431 and the second guide slope 432 constitute a tapered structure. As shown in fig. 2 and 4, when the inner lid 12 is mounted, the lower surface of the guide post 42 abuts against the outer surface of the first guide slope 431, and the pressure limiting valve 30 swings to the right by the driving of the first guide slope 431 and causes the push handle 31 to avoid the driving member 20 during the rising of the inner lid 12. During the process of removing the inner lid (i.e., from the state of the pressure limiting valve in fig. 4 to the state of the pressure limiting valve in fig. 2), when the pressure limiting valve 30 descends, the second guide slope 432 abuts against the lower surface of the mounting recess 111 and drives the pressure limiting valve 30 to rotate toward the right side so as to avoid the driving member 20. The above structure allows the push handle 31 to avoid the driving member 20 when the user removes or installs the inner lid 12, thereby preventing friction between the push handle 31 and the driving member 20 and reducing the damage probability of the pressure limiting valve 30.
As shown in fig. 2, in the technical solution of the present embodiment, before the inner pot cover 12 is mounted on the pot cover body 11, and when the inner pot cover 12 is mounted on the pot cover body 11 to be aligned with each other, the distance from the upper end of the guide block 41 to the driving piece 20 is greater than the distance from the lower end of the guide post 42 to the driving piece 20. Specifically, the above structure ensures that the lower end of the guide post 42 can first contact the first guide slope 431 to perform a normal guide function and prevent the mechanisms from being stuck to each other when the inner lid 12 is mounted.
As shown in fig. 2, in the technical solution of the present embodiment, the shape of the accommodating recess 421 is adapted to the shape of the surface of the guide block 41 facing the guide post 42. Specifically, the accommodating recess 421 in the present embodiment is also of a "<" type, and the above structure enables the guide block 41 to be better engaged with the accommodating recess 421, while the pressure limiting valve 30 can swing more smoothly when the inner lid 12 is mounted or dismounted.
Preferably, the driving member 20 in this embodiment is an electromagnetic valve, the push rod 21 of the electromagnetic valve cooperates with the push handle 31, and the guiding structure 40 enables the pressure limiting valve 30 to rotate around the axis thereof and enables the push handle 31 to avoid the push rod 21 in the process that the inner pot cover 12 is mounted on the pot cover main body 11, and when the inner pot cover 12 is mounted on the pot cover main body 11, the pressure limiting valve 30 resets and enables the push rod 21 to abut against the push handle 31.
As shown in fig. 4 and 5, in the technical solution of the present embodiment, the inner pot cover 12 is provided with a valve seat 50. The pressure limiting valve 30 is disposed on the valve seat 50. Wherein a lifting inclined surface 60 is arranged between the pressure limiting valve 30 and the valve seat 50. In the process that the inner pot cover 12 is mounted on the pot cover main body 11, the first guide inclined surface 431 is abutted with the lower surface of the guide post 42 and drives the pressure limiting valve 30 to rotate, the pressure limiting valve 30 rises under the action of the lifting inclined surface 60, and when the inner pot cover 12 is mounted on the pot cover main body 11, the guide block 41 is embedded into the accommodating concave part 421, and the pressure limiting valve 30 falls back through gravity. Specifically, in the technical solution of this embodiment, the lower end of the pressure limiting valve 30 is provided with a triangular notch, the side edge of the triangular notch forms the lifting inclined plane 60, the valve seat 50 is provided with a convex rib embedded into the triangular notch, and the convex rib is abutted to the lifting inclined plane 60. When the push rod 21 pushes the push handle 31, the pressure limiting valve 30 rotates to the right, and the pressure limiting valve 30 rises and moves away from the exhaust port under the action of the lifting slope 60, thereby achieving exhaust. When the push rod 21 is retracted, the pressure limiting valve 30 falls by gravity, and simultaneously swings back to the left under the action of the lifting slope 60, and the push handle 31 and the push rod 21 are continuously abutted together.
As shown in fig. 4 and 8, in the technical solution of the present embodiment, the side wall of the valve seat 50 is provided with a avoiding opening 51 for avoiding the push handle 31 and the guide block 41. The relief port 51 prevents the push handle 31 and the guide block 41 from interfering with the side wall of the valve seat 50 when the pressure limiting valve 30 is rotated.
As shown in fig. 6 and 7, the lower surface of the pot cover body 11 is provided with an upwardly recessed mounting recess portion 111, the top wall of the mounting recess portion 111 is provided with a gas passing hole 112, the guide post 42 is connected to the side wall of the mounting recess portion 111, and the pressure limiting valve 30 is located in the accommodation recess portion 421 when the inner pot cover 12 is mounted on the pot cover body 11. Specifically, the steam discharged from the exhaust port is discharged from the air passing hole 112 to the outside of the pot cover 10, and the connection area of the guide post 42 to the installation recess 111 is increased by guiding the guide post 42 to be connected to the side wall of the installation recess 111, thereby improving the strength of the guide post 42.
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.
