In this way, the characteristics defined by "first" and "second" may include, explicitly or implicitly, one or more characteristics. In the description of the present invention, "a plurality of" indicates two or more, unless otherwise recommended.
    [037] In describing the present invention, it should be noted that, unless specified or clearly defined, a broad understanding must be made for the terms "installation", "interconnection" and "connection", for example, "connection "it can be a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection due to intermediation or communication between the internal parts of two components. The specific meanings of the terms mentioned above, in the present invention, can be understood according to the specific conditions for those skilled in the art.
    [038] An electric pressure cooker 100, according to an embodiment of the present invention, will be described with reference to Figures 1 to 9. The electric pressure cooker 100, according to the embodiment of the present invention, as shown in Figures 1 to 6, includes a pan body 1 and a pan cover 2.
    [039] The pan cover 2 is arranged on the pan body 1, where the pan cover 2 can be loosely arranged on the pan body 1, that is, the pan cover 2 can be removed from the pan cover 2, and, specify, the pan cover 2 and the pan body 1 can be connected together by a cover tooth structure (not shown), a buckle, a clamping claw or the like. Furthermore, the pan cover 2 can also be connected to the pan body 1 as long as necessary without being released, for example, the pan cover 2 can be connected to the pan body 1 via a articulation and the like, and when the cover needs to be opened, the pan cover 2 can be opened in a twisting way.
    [040] When pan cover 2 is arranged on pan body 1, pan cover 2 can rotate relative to pan body 1. Specifically, when pan cover 2 and pan body 1 are in one detachable structure and a user needs to attach the pan cover 2 for cooking, the pan cover 2 can first be placed on the pan body 1, and then the pan cover 2 is rotated to cover the pan body 1 on its place for cooking.
    [041] When the pan cover 2 and the pan body 1 are of a detachable structure, a joint can be arranged between the pan cover 2 and the pan body 1, for connection; when it is opened, the panel cover 2 can be connected to the pan body 1 as long as necessary, so that the pan cover 2 is prevented from being lost or falling off a table top; and the pan cover 2 can rotate relative to the pan body 1 during self-rotating closure of the pan cover. Because this structure belongs to the prior art, it will not be described in detail.
    [042] As shown in Figures 1 to 6, a magnetic sensitivity switch 3 and a magnetic element 4 are arranged on the pan body 1, and the magnetic element 4 can move between a first position and a second position , relative to the magnetic sensitivity switch 3, so that the control circuit of the electric pressure cooker 100 can be switched on or off, that is, a circuit of the electric pressure cooker 100 can be switched on or off. In other words, when the magnetic element 4 is in the first position, relative to the magnetic sensitivity switch 3, as shown in Figures 5 and 6, the control circuit of the electric pressure cooker 100 is turned on, and the electric pressure cooker 100 can be used for cooking; and when the magnetic element 4 is in the second position, relative to the magnetic sensitivity switch 3, as shown in Figures 3 and 4, the control circuit of the electric pressure cooker 100 is turned off, and the electric pressure cooker 100 cannot be used for cooking.
    [043] Specifically, the magnetic sensitivity switch 3 detects the variance of a magnetic field around it and transmits a level, and a controller detects the high or low level transmitted by the magnetic sensitivity switch 3, to control the connection and switching off the circuit, ie when the magnetic sensitivity switch 3 detects that the magnetic field has been intensified, the magnetic sensitivity switch 3 transmits the high level, and the controller controls the electrical circuit of the electric pressure cooker 100, to let it be turned off; and when the magnetic sensitivity switch 3 detects that the magnetic field has been weakened, the magnetic sensitivity switch 3 transmits the low level, and the controller controls the electrical circuit of the electric pressure cooker 100 to be switched on.
    [044] That is, when the magnetic element 4 is in the first position, relative to the magnetic sensitivity switch 3, the magnetic sensitivity switch 3 detects that the magnetic field is weakened and the magnetic sensitivity switch 3 transmits at the low level, the electrical circuit of the electric pressure cooker 100 is switched on, that is, the electric pressure cooker 100 can be electrified to function. When the magnetic element 4 is in the second position, relative to the magnetic sensitivity switch 3, the magnetic sensitivity switch 3 detects that the magnetic field has been intensified and the magnetic sensitivity switch 3 transmits the high level, the electric circuit of the pan electric pressure cooker 100 is switched off, that is, the electric pressure cooker 100 cannot work.
    [045] It should be understood in this specification that, when the magnetic element 4 is in the first position, relative to the magnetic sensitivity switch 3, the distance between the magnetic element 4 and the magnetic sensitivity switch 3 it can be relatively long; and, when the magnetic element 4 is in the second position, relative to the magnetic sensitivity switch 3, the distance between the magnetic element 4 and the magnetic sensitivity switch 3 can be relatively short. In this way, the purpose that the magnetic sensitivity switch 3 can detect the magnetic field with a different intensity can be achieved.
    [046] The operating principles of the magnetic sensitivity switch 3 and the magnetic element 4 belong to the prior art, and are well known to those skilled in the art, so they will not be described in detail in this specification.
    [047] When the pan cover 2 rotates relative to the pan body 1, the magnetic element 4 can move between the first position and the second position. Specifically, when the pan cover 2 rotates and is closed in place, the pan cover 2 can allow the magnetic element 4 to be in the first position, so that the electrical circuit of the electric pressure cooker 100 is switched on; and, when the pan cover 2 is not closed in place, the pan cover 2 can allow the magnetic element 4 to remain in the second position, so that the electrical circuit of the electric pressure cooker 100 is slid - cattle.
    [048] According to the electric pressure cooker 100 of the embodiment of the present invention, the magnetic element 4 moves by the arrangement of the magnetic sensitivity switch 3 and by the magnetic element 4 and by means of rotation of the pan cover 2, so that the distance between the magnetic sensitivity switch 3 and the magnetic element 4 be changed, and then the connection and disconnection of the electrical circuit of the electric pressure cooker 100 can be controlled, that is, the magnetic sensitivity switch 3 and the magnetic element 4 can constitute a detection device for the electric pressure cooker 100, for detecting if the cover is closed in place; and compared to a cover closure detection device in place in the prior art, the combination of the magnetic sensitivity switch 3 and the magnetic element 4 is of simple structure and of low manufacturing cost.
    [049] In a specific embodiment of the present invention, the magnetic element 4 can be a magnet.
    [050] In some embodiments of the present invention, the pan body 1 may include a housing 11, an inner pan 12 and a housing cover 13. As shown in Figures 1 to 6, the inner pan 12 is arranged in the housing - item 11, an inner container (not shown) can be placed in the inner pot 12, and food materials can be placed in the inner cooking container. An accommodation cavity 121 is defined between the housing 11 and the inner panel 12, and the magnetic sensitivity switch 3 is arranged in the accommodation cavity 121. It must be understood that the parts, which constitute the electrical system of the electric pressure cooker 100, can also be arranged in the housing cavity 121. The housing cover 13 is gloved outside the inner pot 12 and closes the housing cavity 121, and the pot cover 2 can be arranged in the housing cover housing 13 and rotate it.
    [051] Specifically, as shown in Figures 1 to 6, the electric pressure cooker 100 also includes a mounting element 5, the magnetic element 4 is arranged on the mounting element 5, the mounting element 5 can move up and down relative to the housing cover 13 of the pan body 1, and therefore the magnetic element 4 can move between the first position and the second position by means of an up and down movement of the that is, as shown in Figures 1 to 6, when the mounting element 5 moves downwards, the magnetic element 4 also moves downwards, and then the magnetic element 4 moves downwards, from the first position to the second position. It should be noted that the magnetic sensitivity switch 3 is positioned below the magnetic element 4, and the distance between the magnetic sensitivity switch 3 and the magnetic element 4 is reduced, when the magnetic element 4 moves down from the first position to the second position, so that the magnetic sensitivity switch 3 detects that the magnetic field has been intensified and transmits the high level, and the electrical circuit of the electric pressure cooker 100 is switched off.
    [052] Furthermore, the upper end of the mounting element 5 penetrates through the housing cover 13, in order to join with the pan cover 2. In other words, the upper end of the mounting element 5 penetrates through the cover housing 13, the pan cover 2 is attached to the upper end of the mounting element 5, when rotating in the housing cover 13, the mounting element 5 can move in the vertical direction, and then the magnetic element 4 can move between the first position and the second position. It should be noted that, in describing the embodiments of the present invention, the "vertical direction" is shown, for example, by the arrows in Figures 1 to 9.
    [053] More specifically, as shown in Figure 8, a downward guide rail 131 is arranged on the bottom surface of the housing cover 13, where the mounting element 5 can include a body 51 and a push rod 52.
    [054] As shown in Figures 2, 4, 6 and 9, the body 51 is provided with a positioning hole 511 joined with the guide post 131. In other words, the guide post 131 penetrates through the positioning hole 511, to position the mounting element 5 below the housing cover 13, the magnetic element 4 can be arranged on the body 51, the pusher rod 52 is arranged on the body 51, and the upper end of the pusher rod 52 penetrates through the housing cover 13 and expands upwards, so that the pan cover 2 can be joined to the push rod 52, when rotating in the housing cover 13; and, when the pan cover 2 is joined with the push rod 52 and it moves downwards, the push rod 52 can drive the body 51 to move downwards, then the magnetic element 4 moves downwards, from the first position to the second position, and the electrical circuit of the electric pressure cooker 100 is switched off, so that the electric pressure cooker cannot function.
    [055] Specifically, the housing cover 13 can be provided with a through hole 132 penetrating through it, and the upper end of the impeller rod 52 penetrates through the housing cover 13 through the through hole 132 and extends to up.
    [056] Specifically, as shown in Figure 9, an accommodation groove 512, for placing the magnetic element 4, is formed in the body 51, and positioning buckles 513, for positioning the magnetic element 4, are arranged in the groove of accommodation 512. In this way, the magnetic element 4 can be firmly arranged in the body 51. Preferably, the body 51 is a plastic part, which does not affect the magnetism of the magnetic element 4, thus ensuring the efficiency of action of the magnetic element 4 on the magnetic sensitivity switch 3. The positioning buckles 513 can also be plastic parts and are integrally formed in the body 51, and when the magnetic element 4 is arranged in the body 51, the magnetic element 4 it can be fastened in the accommodation slot 512 of the body 51 by using the plastic deformation capacity of the plastic positioning buckles 513.
    [057] Furthermore, the electric pressure cooker 199 also includes an elastic element 6. As shown in Figures 2, 4 and 6, the lower end of the elastic element 6 is positioned on the guide post 131, and the upper end of the element - textile 6 is compressed on the body 51, that is, the upper end of the elastic element 6 is compressed on the lower surface of the body 51. Specifically, when the pan cover 2 rotates and the body 51 moves downwards, the elastic element- tic 6 is in a compressed state, when the pan cover 2 rotates and the elastic element 6 extends upwards, the elastic element 6 can use its elasticity to drive the body 51 to move it upwards, and then the magnetic element 4 moves upwards from the second position to the first position.
    [058] In some optional embodiments of the present invention, the elastic element 6 can be a spring, and the spring is gloved in the guide post 131.
    [059] Specifically, an annular convex rib 21 is arranged at the bottom of the pan cover 2 and provided with a compressible orifice 211, capable of accommodating the push rod 52. When a user covers the pan body 1 with the pan cover 2, and the convex rib 21 is compressed on the push rod 52, for example, as shown in Figures 3 and 4, the magnetic element 4 is located in the second position, the pan cover 2 is not covered in place at the moment , and the electrical circuit of the electric pressure cooker 100 is switched on, so the electric pressure cooker cannot work.
    [060] When the user rotates the pan cover 2 to rotate the compressible orifice 211 to a position in which the driving rod 52 is located, for example, as shown in Figures 5 and 6, a downward force no longer exists above the rod pusher 52, the spring can drive the body 51 so that it moves down at the moment, the pusher rod 52 can be accommodated in the compressible orifice 211, the magnetic element 4 is located in the first position, then the pan cover 2 is covered in place, and the electrical circuit of the electric pressure cooker 100 is switched on, so that the electric pressure cooker can be used for cooking.
    [061] It should be understood from this specification that, when the pan cover 2 is not attached to the pan body 1, for example, as shown in Figures 1 and 2, a downward force also does not exist on the driving rod 52, that is, the spring can drive the body 51 to move upwards at the moment, so that the magnetic element 4 is located in the first position, the electrical circuit of the electric pressure cooker 100 is connected, and the pressure cooker electric pressure can be used for cooking. That is, the electric pressure cooker 100, according to the embodiment of the present invention, can also be used for cooking when the cover is opened. In comparison to the electric pressure cooker, which cannot be used for cooking, when its cover is opened in the prior art, the electric pressure cooker 100 of the present invention can provide more cooking selections for users and satisfy different requirements. users, and is more convenient to use.
    [062] In some optional embodiments of the present invention, as shown in Figures 1 to 6, the electric pressure cooker also includes a screw 7, the screw 7 is arranged on the guide post 131, and the lower end of the spring is compressed into the head end 71 of screw 7. That is, the spring is positioned on the guide post 131 by the screw 7. Specifically, an internal thread can be formed on the guide post 131, and the screw 7 can be joined with a, and stuck in, internal thread.
    [063] As shown in Figures 1 to 6, in some examples of the present invention, the magnetic sensitivity switch 3 can be arranged on a control panel 8 of the electric pressure cooker 100. It should be understood that the control panel control 8 is an important part, which constitutes the electrical system of the electric pressure cooker 100, and the control panel 8 is arranged in the accommodation cavity 121.
    [064] A water retaining part is also arranged in the accommodation cavity 121, and a relatively closed accommodation space 122 is defined between the water retaining part and the wall of the accommodation cavity 121. It should be understood from the present descriptive report that "relatively closed" indicates that the accommodation space 122 is a part of the accommodation cavity 121, and that part is isolated from the other part of the container, in which the inner pan 12 is arranged on the other part. The magnetic sensitivity switch 3 is arranged in the relatively closed accommodation space 122, and specifically, the control panel 8 can be arranged in the accommodation space 122.
