The invention provides a switch structure and a cooking device, wherein the switch structure can be used as a control device for controlling the on-off heating of cooking devices such as an electric cooker, a stew pot or a pressure cooker. It should be noted that the type of application scenario of the present invention does not limit the switch structure and the cooking device of the present invention.

The following will roughly describe the composition and operation principle of the related cooking device by taking the application of the switch structure to the electric cooker as an example. As shown in fig. 1a, the rice cooker may include a key switch 10, an outer casing 20, an inner container 30, an inner pot 40, a pot cover 50, a heating device 60, a magnetic steel temperature limiter 70 and a lever member 80. The key switch 10 is a component moving up and down, and the operation mode of the electric cooker can be switched by toggling the key switch 10, for example, the electric cooker toggles down the key switch 10 to enter a rice cooking mode, a rice cooking indicator lamp is turned on, and the heating device 60 heats at a set high power; the electric cooker is shifted upwards to enter a heat preservation mode by toggling the key switch 10, a heat preservation indicator lamp is turned on, and the heating device 60 heats with set lower power or stops heating. The outer shell 20 is provided with a containing cavity for containing the inner container 30 and the inner pot 40, the inner pot 40 is used for containing food, the upper end of the inner pot 40 is provided with the pot cover 50, and the inner container 30 is further arranged between the outer shell 20 and the inner pot 40 and can enable the inner pot 40 to be heated more uniformly. The heating device 60, the magnetic steel temperature limiter 70 and the lever member 80 are all arranged at the bottom of the inner container 30. Wherein, the magnetic steel temperature limiter 70 is positioned in the approximate middle area of the bottom wall of the inner container 30. The magnetic steel temperature limiter 70 comprises a temperature sensing soft magnet 71 and a permanent magnet 72 which are arranged at intervals along the vertical direction, the temperature sensing soft magnet 71 can be fixedly connected with the inner container 30, and the permanent magnet 72 can be in spring connection with the temperature sensing soft magnet 71 and can move along the vertical direction relative to the temperature sensing soft magnet 71. Note that the temperature-sensitive soft magnet 71 does not always have magnetism, the magnetism of the temperature-sensitive soft magnet 71 changes with a change in temperature, and the magnetism of the temperature-sensitive soft magnet 71 is lost when the temperature-sensitive soft magnet reaches the curie temperature. The curie temperature is the temperature at which the spontaneous magnetization in the magnetic material drops to zero. For example, the curie temperature of the temperature sensitive soft magnet 71 may be 103 ℃. That is, when the temperature is lower than 103 ℃, the temperature sensitive soft magnet 71 is magnetic and can attract the permanent magnet 72 up and maintain the attracted state; when the temperature is higher than 103 deg.c, the temperature sensitive soft magnet 71 loses its magnetism, so that the permanent magnet 72 is separated from the temperature sensitive soft magnet 71 and falls down by gravity. The heating device 60 is arranged in most area of the lower part of the inner container 30 around the magnetic steel temperature limiter 70, and after the heating device 60 is electrified, heat can be generated and transferred to the inner pot 40 to heat food. The lever member 80 connects the switch 10 to the permanent magnet 72 of the alnico temperature limiter 70. The operation of the electric rice cooker according to the above structure will be summarized.

The specific working process is as follows: as shown in fig. 1a, the inner pot 40 with food is first placed in the inner container 30 and attached to the upper surface of the heating device 60, the keyswitch 10 is pressed, the right end of the lever member 80 is pressed, and accordingly the left end of the lever member 80 is lifted, and the permanent magnet 72 is driven to move upward to contact with the temperature-sensitive soft magnet 71. At this time, the temperature in the pot is not raised, and the temperature-sensitive soft magnet 71 is still below the curie temperature, has good magnetism, and can attract the permanent magnet 72 and keep the permanent magnet 72 at the top dead center position. The lifting movement of the lever causes the contact rod 81 fixed on the lever 80 to be out of contact with the metal sheet 82 below the lever, so that the contacts 83 of the upper and lower metal sheets are contacted, the circuit of the heating device is connected, and the heating device 60 heats and conducts heat to the inner pot 40 continuously after being electrified, so as to heat the food in the pot. As shown in fig. 1b, when the temperature of the bottom of the inner pot 40 reaches 103 ℃, the temperature-sensitive soft magnet 71 loses magnetism, the permanent magnet 72 is separated from the temperature-sensitive soft magnet 71 and falls from the top dead center position under the action of gravity, and drives the left end of the lever member 80 to move downward, i.e., the left end of the lever member 80 is pressed downward, as shown in fig. 1b, the contact rod 81 stirs the metal sheet 82 below the contact rod along with the movement of the lever member 80, so that the contacts 83 of the upper and lower metal sheets are separated, the circuit of the heating device 60 is disconnected, and the heating device 60 does not continue to generate heat after being powered off. And, while the left end of the lever member 80 moves downward, the right end of the lever member 80 lifts up and drives the key switch 10 to move upward and reset. In addition, in order to keep the food in the inner pot 40 warm, a thermostatic controller may be installed in the rice cooker to stabilize the temperature within a range. It can be seen that, in the related cooking device, by pressing the key switch 10 to move downwards, the transmission assembly is driven to transmit, so that the heating device 60 is heated when being started to work, and after a certain time of heating, when the temperature in the cooking device reaches a threshold value, the transmission assembly can move correspondingly to close the heating work state of the heating device 60 and drive the key switch 10 to move upwards to reset.

In an embodiment of the invention, a switch structure different from that in the related cooking device and the corresponding cooking device are provided. Specifically, as shown in fig. 2 and 3, the switch structure 1 of the embodiment of the present invention includes a base 111, a slider 12, a rotating device 13, and a lever 14. Specifically, the base 111 may be a component fixedly connected to the outer housing 11 of the cooking device and independent from the outer housing 11, and the outer housing 11 may be a substantially thin-walled component to meet the light-weight requirement of the cooking device; in other embodiments, the base 111 may be integrally formed with the outer housing 11 as a unitary structure. The outer housing 11 encloses a receiving cavity to receive and protect the internal components of the cooking device and to provide support for the mounting and securing of the components. The shape of the base 111 is arbitrary and can be set according to actual needs, and for example, the overall outer contour shape may be a cylindrical shape, or may be a nearly rectangular parallelepiped tube or other shapes. As shown in fig. 4, the slider 12 is slidably connected to the base 111, and the slider 12 is reciprocally movable in a first direction with respect to the base 111. The first direction refers to a moving direction of the slider 12 (vertical direction as shown in fig. 4). Specifically, the base 111 may be a slider bracket that is provided on an inner wall surface of the outer casing 11, is independent of the outer casing 11, and is fixedly connected to the outer casing 11, and the base 111 is provided with a sliding groove that extends in a first direction (an up-down direction shown in fig. 4), along which the slider 12 can slide back and forth relative to the base 111. The shape and structure of the slider 12 are arbitrary and are not particularly limited herein.

As shown in fig. 2 and 4, the rotating device 13 is rotatably connected to the base 111 to abut against the slider 12 in a first direction (vertical direction as shown in fig. 4). The contact means that not only contact but also an interaction force exists between the two members. Specifically, the rotating device 13 may be connected with the outer housing 11 of the cooking apparatus, and the rotating device 13 can rotate relative to the outer housing 11. It should be noted that the rotating device 13 does not need to be kept in contact with the slider 12 all the time in the rotating stroke range of the rotating device 13, and in a stroke range, the rotating device 13 may not be in contact with the slider 12, that is, the rotating device 13 and the slider 12 have relative movement, that is, the rotating device 13 moves while the slider 12 does not move, or the rotating device 13 does not move while the slider 12 moves. In another stroke range, the rotating device 13 may be abutted against the sliding block 12 in a first direction (the up-down direction shown in fig. 4), so that a force in the first direction is generated between the rotating device 13 and the sliding block 12, and the force may be actively applied to the sliding block 12 by the rotating device 13, so that the rotating device 13 can drive the sliding block 12 to move in the first direction, and of course, the force may also be actively applied to the rotating device 13 by the sliding block 12, so that the sliding block 12 can drive the rotating device 13 to move in the first direction. That is, in the operating state, the rotating means 13 and the slider 12 can move synchronously, transmitting between each other to achieve simultaneous movement at the same moment but without the need for time synchronization, i.e. allowing movement of the rotating means 13 or the slider 12 for a period of time to be performed separately.

As shown in fig. 5a, a first end 141 of the lever 14 can abut against the slider 12 to move synchronously with the slider 12, and a second end 142 of the lever 14 opposite to the first end 141 is used for receiving the first force. The contact means that not only contact but also an interaction force exists between the two members. Specifically, as shown in fig. 5a, the lever 14 is located below the sliding block 12, the lever 14 may include a rod member 143 and a magnetic steel member 144, the rod member 143 may be an elongated rod, and the magnetic steel member 144 may be a permanent magnet 72, as known from the foregoing principle, the rod member and the permanent magnet move substantially synchronously, so that the rod member and the permanent magnet may be regarded as a whole, i.e., the lever 14. The first end 141 of the lever 14 may be an end of the rod member 143 abutting the slider 12, and the second end 142 of the lever 14 may be an end of the permanent magnet 72 away from the rod member 143. It should be noted that the slider 12 may be kept in contact with the first end 141 of the lever 14 at all times during the sliding process, so as to keep the two moving synchronously at any time. However, the slider 12 may not be in complete abutment with the first end 141 of the lever 14, i.e. a certain assembly gap may be reserved between the two, so that there is a slight relative movement between the two, but the two are still in a substantially synchronous movement state as a whole. It should be noted that the first force applied to the second end 142 is not always present, but is sometimes present or sometimes absent, which will be described in detail below. The presence or absence of the first force corresponds to the opening and closing of the heating circuit in which the heating device 60 is located, and can be considered as: when the heating circuit is closed, the first acting force exists, and the closing of the heating circuit is correspondingly maintained due to the existence of the first acting force; when the heating circuit is disconnected, the first acting force does not exist, and the heating circuit is correspondingly disconnected by withdrawing the first acting force. Specifically, the type of the first acting force can be adjusted according to actual conditions, and for example, the first acting force can be a magnetic attraction force between magnets (including electromagnets).

As shown in fig. 5a and 5b, the operating state of the second end 142 of the lever 14 changes with the change of the state of the temperature sensitive soft magnet 71, specifically, when the temperature sensitive soft magnet 71 is below the curie temperature, the temperature sensitive soft magnet 71 has good magnetism, and can attract the permanent magnet 72 to move upward and maintain the attraction state, and the second end 142 of the lever 14 is lifted upward, i.e., as shown in fig. 5b, in which the second end 142 of the lever 14 receives an upward acting force in the first direction (the up-down direction shown in fig. 4), i.e., a magnetic force (i.e., a first acting force) from the temperature sensitive soft magnet 71. Correspondingly, in the state shown in fig. 5b, the circuit in which the heating device is located is turned on, and the heating device is turned on. When the heating device is operated to make the temperature sensing soft magnet 71 reach curie temperature, the magnetism of the temperature sensing soft magnet 71 is lost, the permanent magnet 72 is separated from the temperature sensing soft magnet 71, the second end 142 of the lever 14 cancels the magnetic force (i.e. the first acting force), the permanent magnet 72 falls under the action of the self gravity, and the second end 142 of the lever 14 is pressed downwards along with the magnetic force, i.e. the state shown in fig. 5a, in which the second end 142 of the lever 14 is subjected to the downward acting force along the first direction (the up-down direction shown in fig. 4), i.e. the gravity of the rod body member 143 and the permanent magnet 72. Correspondingly, in the state shown in fig. 5a, the circuit in which the heating device is located is open, and the heating device is switched off.

With reference to fig. 4, fig. 5a and fig. 5b, the specific operation of the switch structure 1 is described as follows: the rotating device 13 is rotated by an external force (e.g., a user knob) in a forward direction (e.g., counterclockwise direction in fig. 4) in the second direction to move the slider 12 and the first end 141 of the lever 14 in the forward direction (e.g., downward direction in fig. 5a and 5 b) in the first direction, so that the second end 142 of the lever 14 moves from the closed position to the open position to receive the first force (e.g., magnetic attraction force) (e.g., fig. 5 b). The first direction refers to a moving direction of the slider 12 (vertical direction as shown in fig. 4). The second direction refers to a rotational direction of the rotating means 13 (a direction indicated by an arrow shown in fig. 4). The closed position is a bottom dead center position of the second end of the lever 14, and the open position is a top dead center position of the second end of the lever 14. The rotating device 13 rotates counterclockwise until abutting against the sliding block 12, the sliding block 12 slides downward along the first direction under the pushing of the rotating device 13, as shown in fig. 5a, the sliding block 12 drives the first end 141 of the lever 14 to move downward along the first direction, i.e. presses the first end 141 of the lever 14 downward. Accordingly, the second end 142 of the lever 14 is lifted and moves upward along the first direction to attract the temperature-sensing soft magnet 71, and the movement from the bottom dead center position to the top dead center position is completed, i.e. the state shown in fig. 5a is moved to the state shown in fig. 5b, in which the second end 142 of the lever 14 is under the magnetic force of the temperature-sensing soft magnet 71.

The second end 142 of the lever 14, which cancels the first force, returns from the open position to the closed position, and moves the first end 141 of the lever 14 and the slider 12 in the opposite direction of the first direction (upward direction as shown in fig. 5 b), so as to rotationally reset the rotating device 13 in the opposite direction of the second direction (clockwise direction as shown in fig. 4). Specifically, when the heating device heats up to raise the temperature of the temperature-sensitive soft magnet 71 to the curie temperature, the second end 142 of the lever 14 loses the magnetic force (i.e., the first acting force) acting thereon. The second end 142 of the lever 14 falls back under the action of gravity, i.e. presses down the second end 142 of the lever 14, and returns from the top dead center position to the bottom dead center position, i.e. moves from the state shown in fig. 5b to the state shown in fig. 5 a. Accordingly, the first end 141 of the lever 14 is lifted, and the slider 12 is moved by the first end 141 of the lever 14 to slide upward in the first direction. As shown in fig. 4, the rotating device 13 rotates clockwise by the pushing of the slider 12 and returns to the initial position.

The switch structure comprises a base, a sliding block, a rotating device and a lever, wherein the rotating device rotates in the positive direction along the second direction to drive the sliding block and the first end of the lever to move in the positive direction along the first direction, so that the second end of the lever moves from a closed position to an open position to bear a first acting force; the second end of the lever which cancels the first acting force returns to the closing position from the opening position, and drives the first end of the lever and the sliding block to move along the reverse direction of the first direction so as to drive the rotating device to rotate along the reverse direction of the second direction for resetting. The switch structure of the embodiment of the invention realizes switch control in a rotating mode through the stepped transmission of the rotating device, the sliding block and the lever, and simply and effectively realizes diversified switch modes. Moreover, the rotary device can be operated and displaced greatly by the base protruding out of the outer shell by a small height, and the requirement of a user on operation hand feeling is met while the product is miniaturized.

In some embodiments, as shown in fig. 6a and 6B, the slider 12 has first abutment portions 12A which are abuttable against the rotating means 13 and second abutment portions 12B which are abuttable against the lever 14, which are spaced apart in the first direction (the up-down direction shown in fig. 6a and 6B). Specifically, the structural form of the first abutting portion 12A and the second abutting portion 12B may be set according to actual needs, for example, as shown in fig. 6a, protruding edges are respectively formed on two opposite sides of the slider 12, the rotating device 13 may abut against the protruding edge on the adjacent side, and the lever 14 may abut against the protruding edge on the other side; the top edge and the bottom edge on two opposite sides of the sliding block 12 can be directly used as edges to respectively abut against the rotating device 13 and the lever 14; as shown in fig. 6b, a hole-shaped structure or a groove structure may be formed on the slider 12 as long as the rotating device 13 and the lever 14 can extend into the hole-shaped structure, wherein the hole of the hole-shaped structure may be a through hole or a blind hole.

As shown in fig. 6a and 6B, the rotating device 13 and the lever 14 are spaced in the first direction, so that the first abutting portion 12A and the second abutting portion 12B of the slider 12 are spaced in the first direction by a predetermined distance to cooperate with the transmission. The specific working process is as follows: the rotating device 13 is rotated to abut against the first abutting portion 12A, so that the sliding portion 12 is driven to slide, the sliding block 12 can slide to abut against the second abutting portion 12B and the lever 14, and the lever 14 is further stirred to move. Or, the lever 14 moves to abut against the second abutting portion 12B, so as to push the slider 12 to move, and the slider 12 moves to abut against the first abutting portion 12A and the rotating device 13, so as to drive the rotating device 13 to rotate and reset.

Through set up first butt portion and second butt portion on the slider, realize the transmission of rotary device and slider and the transmission of slider and lever respectively and be connected to realize the multistage linkage of rotary device to the motion of lever.

In some embodiments, as shown in fig. 6B, the first abutting portion 12A is a first through hole 121, the second abutting portion 12B is a second through hole 122, the rotating device 13 penetrates or is partially located in the first through hole 121, and the first through hole 121 allows the rotating device 13 to rotate along the second direction. Specifically, the first through hole 121 and the second through hole 122 may have any shape, and may be substantially rectangular through holes or substantially circular through holes, and in an exemplary embodiment, substantially rectangular through holes are used for the first through hole 121 and the second through hole 122. The cross-sectional areas of the two through holes may be the same or different. The rotating device 13 may completely pass through the first through hole 121, or may be located in the first through hole 121. The rotating device 13 can rotate until the wall surface adjacent to the first through hole 121 abuts against, so as to drive the sliding block 12 to slide, or the slider 12 can move until the wall surface adjacent to the first through hole 121 abuts against the rotating device 13, so as to drive the rotating device 13 to rotate.

The rotation movement of the rotating device 13 generates displacement components in the vertical direction and the horizontal direction, so that the size of the first through hole 121 in the vertical direction needs to be larger than that of the rotating device 13 in the vertical direction, and likewise, the size of the first through hole 121 in the horizontal direction needs to be larger than that of the rotating device 13 in the horizontal direction. Certain space is reserved in the vertical direction and the horizontal direction of the first through hole 121 so that the rotating device 13 can move in the first through hole 121, and the rotating device 13 is effectively prevented from being locked by rotation. Because the slider 12 can move up and down and cannot move along the horizontal direction, the size value of the first through hole 121 in the vertical direction can be designed to be slightly smaller than that in the horizontal direction, so that the rotating device 13 can more effectively realize synchronous movement with the slider 12 in the vertical direction, and the idle stroke of the rotating device 13 is reduced.

As shown in fig. 6b, the first end 141 of the lever 14 is disposed within the second through hole 122 or extends through the second through hole 122, the second through hole 122 allowing movement of the lever 14. Specifically, the first end 141 of the lever 14 may pass through the second through hole 122 completely, or may be located in the second through hole 122. The slider 12 may slide until the wall surface of the second through hole 122 abuts against the lever 14, and the lever 14 may be moved, or the lever 14 may move until the wall surface of the second through hole 122 abuts against, and the slider 12 may be pushed to move. In the process of the lever movement of the lever 14, the lever force generated at the end portion thereof has a force component in the vertical direction and a force component in the horizontal direction, and although the force component in the horizontal direction is small, the upper and lower surfaces adjacent to the second through hole 122 may be damaged due to the accumulation of long-term force. The size of the second through hole 122 in the vertical direction can be designed to be slightly thicker than the thickness of the lever 14, a certain moving space is provided for the lever 14, a part of acting force along the horizontal component is released, the structural integrity of the second through hole 122 is effectively ensured, and therefore the service life of the sliding block 12 is prolonged.

The rotating device penetrates through the first through hole by arranging the first through hole and the second through hole on the sliding block at intervals, so that the rotating device drives the sliding block to move or the sliding block drives the rotating device to move; and the first end of the lever penetrates through the second through hole, so that the sliding block drives the lever to move or the lever drives the sliding block to move. Through set up the through-hole on the slider and can realize being connected of slider and rotary device and slider and lever, simple structure, the transmission is effective.

In some embodiments, as shown in fig. 6b, the clearance between the first through hole 121 and the rotating device 13 in the first direction (the up-down direction shown in fig. 6 b) and the clearance between the second through hole 122 and the lever 14 in the first direction are both smaller than the first preset value M1. Specifically, the first preset value M1 may be set according to actual needs, for example, M1 may be 6 mm. In an exemplary embodiment, the first through hole 121 may have a vertical dimension different from that of the rotating means 13 by 5mm, and the second through hole 122 may have a vertical dimension different from that of the lever 14 by 3 mm. The gap between the first through hole 121 and the rotating device 13 in the direction perpendicular to the first direction is greater than the second preset value M2, and the second preset value M2 is greater than or equal to the first preset value M1. Specifically, the second preset value M2 may also be set according to actual needs, for example, M2 may be 8 mm. In an exemplary embodiment, the size values of the first through hole 121 and the rotating means 13 in the horizontal direction may differ by 10 mm. Through setting up the clearance between first through-hole and second through-hole and rotary device and the lever, can operate the motion of rotary device and lever on the one hand, realize the transmission smoothly, the other direction has also avoided too big and cause the transmission discontinuity and influence user experience in the clearance in first direction, realizes basically continuous synchronous drive. In some embodiments, as shown in fig. 6b and 10, rotating device 13 includes a body 131 and a dial 1314. The body 131 may be used to apply a rotational force in a second direction. Specifically, the body 131 is rotatably connected to the base 111, and the body 131 has a guide structure such that the body 131 can rotate in the second direction with respect to the base 111. The driving lever 1314 is fixedly connected to the inner side of the body 131, and the driving lever 1314 can abut against the sliding block 12 in the first direction. Specifically, the driving lever 1314 is driven by the body 131 to rotate along the second direction, and can abut against the slider 12 to generate an acting force along the first direction, so as to realize the conversion from the rotational motion to the linear motion. The rotating device is arranged in a structural form of the body and the shifting rod, so that the movement form is changed.

In some embodiments, as shown in fig. 6b and 7, body 131 includes an outer sidewall 1312, an end wall 1313. The outer sidewall 1312 is provided with a knob 1315 for applying a rotational force in the second direction. Specifically, the outer wall 1312 may be a substantially cylindrical wall surface closed in the circumferential direction, and the outer case 11 of the cooking apparatus is provided with an opening having substantially the same shape and size as the outer contour of the outer wall 1312 so that the outer wall 1312 can be fitted into the opening and connected to the outer case 11. The outer sidewall 1312 may serve as a guide surface for rotational connection with the outer housing 11 to enable the body 131 to rotate in the second direction relative to the outer housing 11. The knob 1315 is located outside the outer sidewall 1312 and is fixedly connected to or integrally formed with the outer sidewall 1312, and the specific shape and structure of the knob 1315 can be set according to actual needs. The knob 1315 facilitates the user to apply a rotation force along the second direction, so that the body 131 can rotate relative to the outer housing 11, and the operation is convenient and labor-saving.

As shown in fig. 6b, end wall 1313 is fixedly attached to outer side wall 1312 and lever 1314 is fixedly attached to end wall 1313. Specifically, the end wall 1313 is fixedly attached to or integrally formed with one end of the outer side wall 1312. The driving lever 1314 is located on the end wall 1313 on a side close to the slider 12 and protrudes from the wall surface to form an elongated column, so that the column can extend into the first through hole 121 of the slider 12 and can move in the first through hole 121. The cross-sectional shape of the lever 1314 may be circular, rectangular, or other shapes, and the cross-section is a plane perpendicular to the extending direction of the lever 1314. In the exemplary embodiment, toggle 1314 has a circular cross-sectional shape. Taking the forward movement process as an example, the driving lever 1314 rotates along with the rotation of the end wall 1313 until abutting against the inner wall surface of the first through hole 121 of the slider 12, pushing the slider 12 to slide, and completing the transmission of the acting force.

Through setting rotary device to the structure of cylinder body to make things convenient for rotary device's rotary motion, and set up the driving lever, make the first through-hole of slider can overlap and establish on the driving lever, thereby realize conducting step by step of effort, simple structure, the transmission is effective.

In some embodiments, as shown in fig. 6b and 7, the end wall 1313 is further provided with a protruding guide block 1316, the base 111 is provided with a guide slot 112, and the guide block 1316 is rotatable in the second direction within the guide slot 112. Specifically, the end wall 1313 is provided with a guide 1316 protruding from a side thereof adjacent to the slider 12, and may have any shape and configuration, such as a generally rectangular parallelepiped. The outer shell 11 is provided with a guide groove 112 extending along the second direction, and the guide groove 112 may be an annular groove continuously provided in the circumferential direction, or an arc-shaped groove partially provided in the circumferential direction. In the exemplary embodiment, an annular guide groove 112 is employed. The guide block 1316 is capable of sliding along the guide slot 112 to rotate the body 131 in a second direction relative to the outer housing 11. Compared to the end wall 1313 being disposed entirely within the guide slot 112, the contact area between the guide block 1316 and the guide slot 112 is much smaller, resulting in less friction and better rotational efficiency. Of course, in other embodiments, the guide block 1316 may be disposed on the outer housing 11 or the base 111, and the guide slot 112 may be disposed on the end wall 1313. The rotation of the body relative to the base is realized through the matched mode of the guide block and the guide groove, the friction force between the rotating device and the base in the rotating process is effectively reduced, and the rotating efficiency is improved.

In some embodiments, as shown in fig. 7, a stop member 113 for stopping the rotation of the guide block 1316 is disposed in the guide slot 112, and an elastic member 114 is disposed in the guide slot 112 adjacent to the stop member 113. Specifically, the stop member 113 may be a protrusion similar to the guide block 1316, the elastic member 114 is located between the guide block 1316 and the stop member 113, the elastic member 114 can be deformed by an external force and generate a restoring force, the elastic member 114 may be a compression spring or an elastic element such as a rubber cushion, and in an exemplary embodiment, the elastic member 114 is a compression spring. The body 131 is rotated by applying a clockwise force to the body 131, and the elastic member 114 in a free state is gradually pressed to be deformed and generate a reaction force opposite to the direction of the external force, i.e., the restoring force. After the external force is removed, the restoring force can rotate the body 131 counterclockwise and restore to the original position. It can be understood that the lever drives the sliding motion, the sliding block drives the rotating device to move, and in the whole mechanical motion transmission process, the sliding block can not enable the rotating device to completely return to the initial position due to the existence of mechanical losses such as friction force. Therefore, the rotating device can be completely reset by arranging the elastic piece to assist the rotating device, and the structure is simple and easy to produce and manufacture.

In some embodiments, as shown in fig. 7, end wall 1313 of body 131 encloses third through-bore 1311. Specifically, the end wall 1313 has a third through hole 1311, the cover 15 can be embedded in the outer side of the body 131, and the cover can protect some parts of the body 131, so that the entering of dust or liquid is effectively reduced, and the service life of the switch structure is prolonged. The cover 15 may further be provided with an indication panel 132 to visualize the operation mode of the cooking device, and the connection circuit of the indication lamp on the indication panel 132 may be accessed through the third through hole 1311.

As shown in fig. 8, the body 131 further includes an inner wall surface 131B disposed at an inner edge of the end wall 1313, and the base 111 is further provided with a limiting structure 115, wherein the limiting structure 115 is at least partially disposed in the third through hole 1311 and abuts against the inner wall surface 131B. Specifically, the limiting structure 115 is connected to the base 111, and the limiting structure 115 is stationary relative to the outer housing 11 in the horizontal direction (i.e., stationary relative to the base) and can move relative to the outer housing 11 in the vertical direction to a small extent. The end wall 1313 has an arcuate inner wall surface 131B extending in the second direction, and the stopper 115 may be located wholly or partially within the third through hole 1311 so that one end of the stopper 115 can abut the inner wall surface 131B.

As shown in fig. 8, the inner wall surface 131B is provided with a stopper groove 131A, and the inner wall surface 131B can rotate relative to the stopper structure 115 to allow the stopper structure 115 to be inserted into and removed from the stopper groove 131A. Specifically, when the stopper structure 115 is in contact with the inner wall surface 131B, the body 131 is rotated clockwise, the inner wall surface 131B can rotate relative to the stopper structure 115, and the stopper groove 131A is engaged with the stopper structure 115, and the engaging force between the stopper groove 131A and the stopper structure 115 is slightly greater than the restoring force of the elastic member, so as to limit the body 131 from continuing to rotate and maintain the engaged state with the stopper structure 115. When the second end of the lever falls back, the resilience force of the first end of the lever is larger than the acting force of the clamping of the limiting groove 131A and the limiting structure 115, so that the limiting structure 115 can be separated from the limiting groove 131A, and the body 131 can be rotated counterclockwise to return to the initial position.

Through set up limit structure on the base, the end wall sets up the spacing groove, through the cooperation of limit structure and spacing groove to the rotation of restriction body, the convenience of use is promoted to the rotation stroke that like this can effectual control body.

Optionally, as shown in fig. 9, one end of the limiting structure 115 abuts against the inner wall surface 131B, and the other end of the limiting structure 115 is provided with the energy storage structure 116. Specifically, the limiting structure 115 has two opposite ends, one of the ends abuts against the inner wall surface 131B, and the other end is connected with the energy storage structure 116. When the stopper structure 115 is not engaged with the stopper groove 131A, the stopper structure 115 is in a compressed state by the energy accumulating structure 116 to be elastically held in contact with the inner wall surface 131B of the end wall 1313, and the compression force in the energy accumulating state is larger than the restoring force of the elastic member, thereby restricting the movement of the body 131. When the position-limiting structure 115 is engaged with the position-limiting groove 131A, the position-limiting structure 115 is still in a compressed state, and since the position-limiting structure 115 moves upward by a small distance to engage with the position-limiting groove 131A, the compressive force applied when the position-limiting structure 115 is engaged with the position-limiting groove 131A is smaller than the state when the position-limiting structure 115 is disengaged from the position-limiting groove 131A. Through set up the motion state of energy storage structure with the effective control body on limit structure, further improved the stability of switch structure operation.

The following concrete process that combines the rotary device of tube-shape appearance to the switch structure in above-mentioned embodiment introduces briefly, when needing to open the culinary art device and get into heating operating condition, the user applys the revolving force on the knob, whole rotary device rotates for the shell body, and drive slider and lever motion, so that the lever lifts permanent magnet to temperature sensing soft magnet actuation, heat to the temperature sensing soft magnet and heat up and exceed the temperature threshold, thereby make permanent magnet break away from temperature sensing soft magnet and break off heating circuit, and drive the lever motion, and then replace slider and rotatory pivot backsliding and backspinning and reset, at the in-process that resets, can receive the effect of energy storage structure and elastic component auxiliary force, so that the knob can reset to the state before not acting on user's revolving force.

In other embodiments, the body 131 may have other specific structural forms. As shown in fig. 10 and 11, the body 131 includes an arc-shaped wall 133 and a connecting body 134. The arc wall 133 has two opposite ends in the circumferential direction, the arc angle corresponding to the arc wall 133 can be adjusted according to actual needs, for example, 45 degrees, the arc wall 133 includes an outer side surface and an inner side surface which are oppositely arranged, and the outer side surface is provided with a knob 1315 for applying a rotating force in the second direction. Specifically, as shown in fig. 11, the arc-shaped wall 133 extends in the second direction and serves as a guide wall surface for the rotation of the rotating device 13. The knob 1315 is fixedly attached to the outer side surface of the arc-shaped wall 133. The knob 1315 is fixedly connected to or integrally formed with the outer side of the arc-shaped wall 133, and the knob 1315 can facilitate the rotation of the rotating device 13, thereby facilitating the operation of a user. The connecting member 134 is fixedly connected to the inner side surface of the arc-shaped wall 133 and rotatably connected to the base 111, and the driving lever 1314 is fixedly connected to the connecting member 134. In particular, the connecting body 134 may be an elongated rod member having a length extending substantially perpendicular to the direction of extension of the curved wall 133. The connecting body 134 is rotatably coupled to the base 111, and the knob 1315 is rotated to rotate the connecting body 134 in a second direction relative to the base 111. The driving lever 1314 is fixedly connected with the connecting body 134 and is arranged on the inner side of the inner side surface of the arc-shaped wall 133, and the driving lever 1314 can be abutted with the sliding block 12 in the first direction. Specifically, a driving lever 1314 is formed on one side of the connecting body 134 close to the sliding block 12 in a protruding manner, the driving lever 1314 can be a long bar-shaped object, and the distance between the center of the connecting body 134 and the rotation center is smaller than the distance between the inner side surface of the arc-shaped wall 133 and the rotation center. The driving lever 1314 can extend into the first through hole 121 of the slider 12 and can move within the first through hole 121. The cross-sectional shape of the lever 1314 may be circular, rectangular, or other shapes, and the cross-section is a plane perpendicular to the extending direction of the lever 1314. In the exemplary embodiment, dial 1314 is circular in cross-sectional shape. Taking the forward motion state as an example, the driving lever 1314 rotates along with the rotation of the connecting body 134 until the driving lever abuts against the inner wall surface of the first through hole 121 of the slider 12, so as to push the slider 12 to slide, thereby completing the conduction of the acting force. The rotating device is arranged into a rod-shaped piece which can rotate relative to the base, so that the flexibility of the structural arrangement of the rotating device is improved. In other embodiments, as shown in fig. 10 and 11, one end of the connecting body 134 is fixedly connected to the inner side surface of the arc-shaped wall 133, the other end of the connecting body 134 is provided with a fourth through hole 1341, and the fourth through hole 1341 is rotatably sleeved on the base 111. Specifically, the connecting body 134 has two opposite ends, one end of the connecting body is fixedly connected to the inner side surface of the arc-shaped wall 133, and the other end of the connecting body is provided with a fourth through hole 1341 for being sleeved on the base 111, so that the connecting body 134 is rotatably connected with the base 111. Through set up the through-hole at the connector, realize that rotary device and base rotate to be connected, simple structure easily manufacturing.

Alternatively, as shown in fig. 11, an elastic member 114 is disposed between the other end of the connecting body 134 and the base 111. Specifically, a torsion spring is sleeved between the other end of the connecting body 134 and the base 111, one end of the torsion spring is fixedly connected with the base 111, the other end of the torsion spring is fixedly connected with the other end of the connecting body 134, and the rotation direction of the torsion spring is the same as the rotation direction of the connecting body 134. The torsion spring can generate a restoring force opposite to the rotation direction with the movement of the connection body 134. The specific working process of the switch structure in this embodiment is as follows: when an external force is applied, the toggle knob 1315 rotates clockwise, and drives the toggle lever 1314 to move to abut against the slider 12, so as to push the slider 12 to move downward, thereby pressing the first end 141 of the lever 14 downward, and lifting the second end 142 of the lever 14 to attract the temperature sensing soft magnet 71, and before the curie temperature is reached, the second end 142 of the lever 14 is always attracted to the temperature sensing soft magnet 71, that is, the attraction force of the magnet is greater than the restoring force generated by the torsion spring, so that the rotating device 13 does not return to the initial position after the external force is removed. After the temperature-sensing soft magnet 71 reaches the curie temperature, the magnetism is lost, the second end 142 of the lever 14 falls back under the action of gravity, accordingly, the first end 141 of the lever 14 rebounds and rises upwards to push the slider 12 to move upwards, and the slider 12 drives the rotating device 13 to rotate anticlockwise. Due to the existence of mechanical loss such as friction, the slider 12 cannot fully return the rotation device 13 to the initial position, so that the full return of the rotation device 13 can be assisted by providing a torsion spring. Through set up the elastic component between connector and base, the rotation process that is more convenient and effective.

In other embodiments, as shown in fig. 12, the cover 15 is disposed on the outer side of the body 131, the cover 15 is fixedly connected to the base 111, the cover 15 includes an end wall 151 and a side wall 152 disposed at the edge of the end wall 151, and the side wall 152 extends along the circumferential direction to form a circumferential gap 1521.

The inner diameter of the side wall 152 may be slightly larger than the distance between the arc wall 133 and the center of rotation, so that the cover 15 can cover the connecting body 134 and the arc wall 133 well to protect these components. The end wall 151 may serve as an indicator panel on which an indicator light may be mounted, and may also serve to mount power circuitry for the indicator light within the receiving cavity. The curved wall 133 is disposed adjacent to the side wall 152 and closes the circumferential gap 1521, the knob 1315 is rotatable in the circumferential gap 1521 in the second direction, and the connector 134 and the lever 1314 are both adjacent to the end wall 151.
