The invention provides a switch structure and a cooking device, wherein the switch structure can be used as a control device for controlling the heating of the cooking devices such as an electric cooker, a stewpot or a pressure cooker to be started and closed. It should be noted that the application scenario type of the present invention is not limited to the switch structure and the cooking device of the present invention.

The following uses the switch structure applied to the electric cooker as an example to describe the composition and working principle of the related cooking device. As shown in fig. 1a, the electric rice cooker may include a key switch 10, an outer case 20, a liner 30, an inner pot 40, a cover 50, a heating device 60, a magnetic steel thermostat 70, and a lever 80. Wherein the key switch 10 is a vertically moving component, and the key switch 10 is shifted to switch the working mode of the electric cooker, for example, the electric cooker with the key switch 10 is shifted downwards to enter a rice cooking mode, a rice cooking indicator light is on, and the heating device 60 is heated with a set higher power; the electric cooker with the dial-up key switch 10 enters a heat preservation mode, a heat preservation indicator lamp is on, and the heating device 60 heats or stops heating with set smaller power. 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 arranged between the outer shell 20 and the inner pot 40, so that the inner pot 40 can 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 located in a substantially middle region of the bottom wall of the liner 30. The magnetic steel temperature limiter 70 comprises temperature sensing soft magnets 71 and permanent magnets 72 which are arranged at intervals along the vertical direction, wherein the temperature sensing soft magnets 71 can be fixedly connected with the liner 30, and the permanent magnets 72 can be in spring connection with the temperature sensing soft magnets 71 and can move along the vertical direction relative to the temperature sensing soft magnets 71. The temperature sensitive soft magnet 71 does not always have magnetism, but the magnetism of the temperature sensitive soft magnet 71 changes with a change in temperature, and the temperature sensitive soft magnet 71 loses magnetism after reaching the curie temperature. Curie temperature refers to the temperature at which the spontaneous magnetization in a 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 the permanent magnet 72 can be attracted and kept in the attracted state; when the temperature is higher than 103 ℃, the temperature-sensitive soft magnet 71 loses magnetism, so that the permanent magnet 72 is separated from the temperature-sensitive soft magnet 71 and falls under the action of gravity. The heating device 60 is disposed around the magnetic steel temperature limiter 70 in most of the lower portion of the inner container 30, and after the heating device 60 is powered on, heat can be generated and transferred to the inner pot 40 to heat food. The lever 80 connects the switch 10 to the permanent magnet 72 of the magnetic temperature limiter 70. Hereinafter, the operation of the rice cooker will be generally summarized according to the above-described structural composition.

The specific working process is as follows: as shown in fig. 1a, the inner pot 40 containing food is first put into the inner container 30 and attached to the upper surface of the heating device 60, the key switch 10 is depressed, the right end of the lever member 80 is depressed, and accordingly the left end of the lever member 80 is lifted up, and the permanent magnet 72 is driven to move upward to contact the temperature-sensitive soft magnet 71. At this time, the temperature in the pot is not raised yet, and the temperature-sensitive soft magnet 71 is still below the curie temperature, and 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 bar 81 fixed to the lever 80 to be out of contact with the metal sheet 82 below it, thereby causing the contacts 83 of the upper and lower metal sheets to be in contact, the circuit of the heating means is completed, and the heating means 60 heats up and continuously transfers heat to the inner pot 40 after being energized to heat the food in the pot. When the temperature of the bottom of the inner pot 40 reaches 103 ℃, the temperature sensing soft magnet 71 loses magnetism, the permanent magnet 72 is separated from the temperature sensing 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 downwards, namely, the left end of the lever member 80 is pressed down, as shown in fig. 1b, the contact rod 81 stirs the metal sheet 82 below the lever member 80 along with the movement of the lever member 80, so that the contacts 83 of the upper metal sheet and the lower metal sheet are separated, the circuit of the heating device 60 is disconnected, and the heating device 60 does not continue to generate heat after power failure. And, the left end of the lever member 80 moves downward while the right end of the lever member 80 is lifted up, and drives the key switch 10 to move upward for reset. In addition, in order to keep the temperature of the food in the inner pot 40 warm, a thermostat controller may be provided in the electric rice cooker to stabilize the temperature thereof within a range. In the related cooking device, the key switch 10 is pressed to move downward, so that the driving assembly is driven to drive the driving assembly to drive the heating device 60 to start to heat in a working state, and after a certain time of heating, when the temperature in the cooking device reaches a threshold value, the driving assembly correspondingly moves to close the heating working state of the heating device 60 and drive the key switch 10 to move upward to reset.

In an embodiment of the invention, a switch structure different from that of a related cooking device and a 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 casing 11 of the cooking apparatus and independent from the outer casing 11, and the outer casing 11 may be a substantially thin-walled member to meet the requirement of light weight of the cooking apparatus; in other embodiments, the base 111 may be integrally formed with the outer housing 11 as a unitary structure. The outer case 11 encloses a receiving chamber to receive and protect the internal components of the cooking apparatus and to provide support for the installation and fixation of the partial components. The shape of the base 111 may be set according to actual needs, and for example, the overall outer contour shape may be a cylindrical shape, or may be an approximately rectangular cylinder or other shape. 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 the movement direction of the slider 12 (the up-down direction as shown in fig. 4). Specifically, the base 111 may be a slide bracket that is disposed on an inner wall surface of the outer casing 11 and is independent of the outer casing 11 and fixedly connected with the outer casing 11, the base 111 is provided with a slide groove extending along a first direction (an up-down direction as shown in fig. 4), and the slide 12 can slide reciprocally along the slide groove 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 with the base 111 to abut against the slider 12 in a first direction (up-down direction as shown in fig. 4). The abutment means not only contact but also interaction force between the two members. In particular, the rotation device 13 may be connected to the outer housing 11 of the cooking device, and the rotation device 13 is rotatable with respect to the outer housing 11. It should be noted that, in the rotation stroke range of the rotation device 13, the rotation device 13 does not need to be always kept in abutment with the slider 12, and in a stroke range, the rotation device 13 may not be in contact with the slider 12, that is, the rotation device 13 and the slider 12 have relative movement, that is, the rotation device 13 moves while the slider 12 does not move, or the rotation device 13 does not move while the slider 12 moves. In another range of travel, the rotating device 13 may be abutted against the slider 12 in a first direction (up-down direction as shown in fig. 4), so that a force along the first direction is generated between the rotating device 13 and the slider 12, the force may be actively applied to the slider 12 by the rotating device 13, so that the rotating device 13 can drive the slider 12 to move along the first direction, or, of course, the force may be actively applied to the slider 12 to the rotating device 13, so that the slider 12 can drive the rotating device 13 to move along the first direction. That is, in the operating state, the rotating device 13 and the slide 12 can move synchronously, and the transmission between them realizes simultaneous movement at the same time, but does not need to synchronize at the same time, i.e. the movement of the rotating device 13 or the slide 12 is allowed to be carried out independently for a period of time.

As shown in fig. 5a, a first end 141 of the lever 14 can abut 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 adapted to receive a first force. The abutment means not only contact but also interaction force between the two members. Specifically, as shown in fig. 5a, the lever 14 is located below the slider 12, and the lever 14 may include a rod member 143 and a magnetic steel member 144, where the rod member 143 may be an elongated rod, and the magnetic steel member 144 may be a permanent magnet 72, and as known from the foregoing principle, the rod member and the permanent magnet are substantially synchronously moved, so that the rod member and the permanent magnet may be considered 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 remote from the rod member 143. It should be noted that, during the sliding process, the slider 12 may always keep abutting against the first end 141 of the lever 14, so as to keep the synchronous movement of the two at any time. However, the slider 12 may not be fully abutted against the first end 141 of the lever 14, i.e., a certain assembly clearance 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 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 and sometimes absent, which will be described in detail below. The presence or absence of the first force corresponds to the heating circuit in which the heating device 60 is turned on and off, and can be considered as: when the heating circuit is closed, a first acting force exists, and the first acting force correspondingly keeps the heating circuit closed; when the heating circuit is disconnected, the first acting force does not exist, and the withdrawal of the first acting force correspondingly disconnects the heating circuit. Specifically, the type of the first acting force can be adjusted according to practical situations, for example, the first acting force can be a magnetic attraction force between magnets (including electromagnets).

As shown in fig. 5a and 5b, the working state of the second end 142 of the lever 14 is changed according to the state of the temperature sensing soft magnet 71, specifically, when the temperature sensing soft magnet 71 is below the curie temperature, the temperature sensing soft magnet 71 has good magnetism, and can attract the permanent magnet 72 to move upwards and keep the attracted state, namely, the second end 142 of the lever 14 is lifted upwards, namely, the state shown in fig. 5b, in which the second end 142 of the lever 14 is subjected to a force acting upwards in a first direction (up-down direction as shown in fig. 4), namely, a magnetic force (namely, a first force) from the temperature sensing soft magnet 71. Correspondingly, in the state shown in fig. 5b, the circuit where the heating device is located is turned on, and the heating device is turned on to be in a heating state. When the heating means is operated such that the temperature sensitive soft magnet 71 reaches the curie temperature, the temperature sensitive soft magnet 71 loses magnetism, the permanent magnet 72 is separated from the temperature sensitive soft magnet 71, the second end 142 of the lever 14 is disengaged, the magnetic force (i.e., the first force) is cancelled, the permanent magnet 72 falls down by its own weight, and the second end 142 of the lever 14 is depressed, i.e., the state shown in fig. 5a, in which the second end 142 of the lever 14 is subjected to a force downward in the first direction (up-down direction as shown in fig. 4), i.e., the weight of the lever body 143 and the permanent magnet 72. Correspondingly, in the state shown in fig. 5a, the circuit where the heating device is located is opened, and the heating device is turned off in the heating state.

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

The second end 142 of the lever 14, which is retracted from the open position to the closed position, moves the first end 141 of the lever 14 and the slider 12 in a direction opposite to the first direction (upward direction as shown in fig. 5 b) to rotationally reset the rotary device 13 in a direction opposite to the second direction (clockwise direction as shown in fig. 4). Specifically, when the heating means heats the temperature-sensitive soft magnet 71 to reach the curie temperature, the magnetism is lost, and the second end 142 of the lever 14 also loses the magnetic force (i.e., the first acting force) originally acting thereon. The second end 142 of the lever 14 falls back under gravity, i.e. presses the second end 142 of the lever 14, and moves from the top dead center position back to the bottom dead center position, i.e. from the state shown in fig. 5b to the state shown in fig. 5 a. Correspondingly, the first end 141 of the lever 14 is lifted, and the slider 12 slides upwards along the first direction under the driving of the first end 141 of the lever 14. As shown in fig. 4, the rotating device 13 is rotated clockwise by the pushing of the slider 12 and returns to the original position.

The switch structure comprises a base, a sliding block, a rotating device and a lever, wherein the rotating device rotates in the forward direction along the second direction so as to drive the sliding block and the first end of the lever to move in the forward direction along the first direction, so that the second end of the lever moves from a closed position to an open position to bear first acting force; the second end of the lever which withdraws 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 reversely along the first direction so as to drive the rotating device to rotate reversely along the second direction for resetting. According to the switch structure provided by the embodiment of the invention, the switch control is realized in a rotating mode through the graded transmission of the rotating device, the sliding block and the lever, and the diversified switch modes are simply and effectively realized. And moreover, the larger operation displacement of the rotating device can be realized through the smaller height of the base protruding out of the outer shell, and the requirement of a user on the 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 abuttable to the rotating device 13 and second abutment portions 12B abuttable to the lever 14, which are spaced apart in a first direction (up-down direction as shown in fig. 6a and 6B). Specifically, the structural forms 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 to form convex edges on two opposite sides of the slider 12 respectively, the rotating device 13 may abut against the convex edge on the adjacent side, and the lever 14 may abut against the convex 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 structure or a groove structure may be formed on the slider 12, so long as the rotating device 13 and the lever 14 can extend into the hole structure, wherein the hole of the hole 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 apart along the first direction, so that the first abutting portion 12A and the second abutting portion 12B of the slider 12 are spaced apart a predetermined distance along the first direction to cooperate for transmission. The specific working process is as follows: the rotating device 13 is rotated to be abutted against the first abutting part 12A, so that the sliding 12 is driven to slide, the sliding block 12 can slide to enable the second abutting part 12B to be abutted against the lever 14, and the lever 14 is moved. Or, the lever 14 moves to be abutted against the second abutting part 12B, so that the sliding block 12 is pushed to move, and the sliding block 12 moves to enable the first abutting part 12A to be abutted against the rotating device 13, so that the rotating device 13 is driven to rotate and reset.

The first abutting part and the second abutting part are arranged on the sliding block, so that the transmission connection of the rotating device and the sliding block and the transmission connection of the sliding block and the lever are respectively realized, and the multistage linkage of the motion from the rotating device to the lever is realized.

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, and the rotating device 13 is located through or partially in the first through hole 121, and the first through hole 121 allows the rotating device 13 to rotate in 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 the exemplary embodiment, the first through hole 121 and the second through hole 122 each have a substantially rectangular through hole. The cross-sectional areas of the two through holes can be the same or different. The rotating device 13 may pass completely 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 that the sliding 12 is driven to slide, or the sliding block 12 can move until the wall surface adjacent to the first through hole 121 abuts against the rotating device 13, so that the rotating device 13 is driven to rotate.

The rotational movement of the rotation means 13 generates displacement components in the vertical direction as well as in the horizontal direction, so that the dimension of the first through hole 121 in the vertical direction needs to be larger than the dimension of the rotation means 13 in the vertical direction, and likewise, the dimension of the first through hole 121 in the horizontal direction needs to be larger than the dimension of the rotation means 13 in the horizontal direction. Through reserving certain space in the vertical direction and the horizontal direction of the first through hole 121, the rotating device 13 can move in the first through hole 121, and the rotating device 13 is effectively prevented from being blocked by rotation. Since the slider 12 can move up and down and cannot move in the horizontal direction, the dimension 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 synchronous movement of the rotating device 13 and the slider 12 in the vertical direction can be more effectively realized, 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 completely pass through the second through hole 122, or may be located in the second through hole 122. The slide block 12 can slide until the wall surface of the second through hole 122 is abutted against the lever 14, so that the lever 14 is moved, or the lever 14 can be moved to be abutted against the wall surface of the second through hole 122, so that the slide block 12 is pushed to move. The lever 14 has a force component in the vertical direction and a force component in the horizontal direction due to the lever force generated from the end portion thereof during the lever movement, and the upper and lower surfaces adjacent to the second through hole 122 may be damaged due to the accumulation of the long-term force although the force in the horizontal direction is small. The second through hole 122 can be designed to be slightly thicker than the thickness of the lever 14 in the vertical direction, so that a certain movable 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 the service life of the sliding block 12 is prolonged.

The sliding block is provided with a first through hole and a second through hole at intervals, and the rotating device is arranged in the first through hole in a penetrating way, 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 is arranged in the second through hole in a penetrating way, so that the sliding block drives the lever to move or the lever drives the sliding block to move. The sliding block and the rotating device can be connected through the through hole formed in the sliding block, and the sliding block and the lever are connected, so that the structure is simple, and transmission is effective.

In some embodiments, as shown in fig. 6b, the gap between the first through hole 121 and the rotating device 13 in the first direction (up-down direction shown in fig. 6 b) and the gap between the second through hole 122 and the lever 14 in the first direction are 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 6mm. In an exemplary embodiment, the first through hole 121 may have a dimension value in the vertical direction different from that of the rotation device 13 by 5mm, and the second through hole 122 may have a dimension value in the vertical direction different from that of the lever 14 by 3mm. The gap between the first through hole 121 and the rotating device 13 in the direction perpendicular to the first direction is greater than a 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 8mm. In an exemplary embodiment, the first through hole 121 may be different from the rotating device 13 in size value in the horizontal direction by 10mm. Through setting up the clearance between first through-hole and second through-hole and rotary device and the lever, can move the motion of rotary device and lever on the one hand, realize the transmission smoothly, the clearance is too big and cause the transmission discontinuous and influence user experience in the first direction also has been avoided to the other direction, realizes basic continuous synchronous transmission. In some embodiments, as shown in fig. 6b and 10, the rotary device 13 includes a body 131 and a lever 1314. The body 131 may be used to apply a rotational force in the second direction. Specifically, the body 131 is rotatably connected with the base 111, and the body 131 has a guide structure so that the body 131 can be rotated in the second direction with respect to the base 111. The lever 1314 is fixedly connected to the inner side of the body 131, and the lever 1314 may abut against the slider 12 in the first direction. Specifically, the lever 1314 is also rotated in the second direction under the driving of the body 131, and can abut against the slider 12 to generate a force in the first direction, so as to realize the transformation from the rotational motion to the linear motion. The rotary device is arranged in the structure form of the body and the deflector rod, so that the change of the movement form is realized.

In some embodiments, as shown in fig. 6b and 7, body 131 includes an outer side wall 1312, an end wall 1313. The outer side wall 1312 is provided with a knob 1315 for applying a rotational force in the second direction. Specifically, the outer side wall 1312 may be a substantially cylindrical wall surface that is closed in the circumferential direction, and the outer casing 11 of the cooking apparatus is provided with an opening having substantially the same shape and size as the outer contour of the outer side wall 1312, so that the outer side wall 1312 can be fitted into the opening to be connected with the outer casing 11. The outer side wall 1312 may serve as a guide surface rotatably coupled to the outer housing 11 to enable the body 131 to rotate in a second direction relative to the outer housing 11. The knob 1315 is located outside the outer sidewall 1312 and is fixedly connected 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 can facilitate the user to apply a rotation force along the second direction, so that the body 131 rotates relative to the outer housing 11, which is convenient and labor-saving.

As shown in FIG. 6b, end wall 1313 is fixedly coupled to outer side wall 1312 and lever 1314 is fixedly coupled to end wall 1313. Specifically, end wall 1313 is fixedly attached to or integrally formed with one end of outer side wall 1312. The lever 1314 is located on a side of the end wall 1313 adjacent the slider 12 and projects from the wall to form an elongated post that extends into the first through-hole 121 of the slider 12 and is movable within the first through-hole 121. The cross-sectional shape of the lever 1314 may be circular, rectangular, or any other shape, and the cross-section refers to a plane perpendicular to the direction in which the lever 1314 extends. In an exemplary embodiment, the cross-sectional shape of the lever 1314 is circular. Taking the forward movement process as an example, the 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, so as to push the slider 12 to slide, thereby completing the conduction of the acting force.

Through setting up rotary device into 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 to establish on the driving lever, thereby realize the conduction 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 within the guide slot 112 in a second direction. Specifically, the end wall 1313 is provided with a guide block 1316 protruding from a side thereof adjacent to the slider 12, and may have any shape and structure, for example, a substantially rectangular parallelepiped projection. The outer casing 11 is provided with a guide groove 112 extending along the second direction, and the guide groove 112 may be a circular groove continuously opened in the circumferential direction or an arc groove partially opened in the circumferential direction. In the exemplary embodiment, an annular guide slot 112 is employed. The guide block 1316 is capable of sliding along the guide groove 112 to rotate the body 131 in the second direction relative to the outer case 11. Compared with the arrangement of the end wall 1313 in the guide groove 112, the contact area between the guide block 1316 and the guide groove 112 is much smaller, so that the friction force is smaller, and the rotation efficiency can be improved better. Of course, in other embodiments, the guide block 1316 may be provided on the outer housing 11 or the base 111, and the guide groove 112 may be provided on the end wall 1313. The body is rotated relative to the base in a mode of matching the guide block and the guide groove, so that 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 stopper 113 for blocking the rotation of the guide block 1316 is provided in the guide groove 112, and a resilient member 114 adjacent to the stopper 113 is provided in the guide groove 112. Specifically, the stop member 113 may be a protrusion with a similar structure 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 is capable of deforming under an external force and generating a restoring force, and the elastic member 114 may be an elastic element such as a compression spring or a rubber cushion, and in an exemplary embodiment, the elastic member 114 is a compression spring. The body 131 is rotated by applying a force clockwise, so that the elastic member 114 in a free state is gradually compressed to be deformed, and a reaction force opposite to the external force is generated, 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 transmission process of mechanical motion, 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 and the like. Therefore, the elastic piece can be used for assisting the rotating device to reset completely, and the structure is simpler and easy to manufacture.

In some embodiments, as shown in fig. 7, an end wall 1313 of body 131 encloses a third through bore 1311. Specifically, the end wall 1313 has a third through hole 1311, and the outer side of the body 131 can be embedded into the cover body 15, so that the cover body can protect part of components of the body 131, thereby effectively reducing dust or liquid entering and prolonging the service life of the switch structure. An indication panel 132 may be further disposed on the cover 15 to visualize the operation mode of the cooking apparatus, and a connection line 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, where the limiting structure 115 is at least partially located 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 a horizontal direction (i.e., stationary relative to the base), and may have a small range of movement relative to the outer housing 11 in a vertical direction. The end wall 1313 has an arcuate inner wall surface 131B extending in the second direction, and the stop structure 115 may be located wholly or partially within the third through hole 1311 such that one end of the stop structure 115 can abut the inner wall surface 131B.

As shown in fig. 8, the inner wall surface 131B is provided with a limiting groove 131A, and the inner wall surface 131B can rotate relative to the limiting structure 115 to enable the limiting structure 115 to be clamped into and separated from the limiting groove 131A. Specifically, in the state that the limiting structure 115 is kept in contact with the inner wall surface 131B, the body 131 is rotated clockwise, the inner wall surface 131B can rotate relative to the limiting structure 115, and is rotated to the limiting groove 131A to be clamped with the limiting structure 115, and the acting force of the clamping between the limiting structure and the limiting groove is slightly greater than the restoring force of the elastic member, so that the body 131 is limited to continue to rotate, and the clamping state with the limiting structure 115 is maintained. When the second end of the lever falls back, the resilience force of the first end of the lever is greater than the acting force of the engagement between 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 rotates anticlockwise to return to the initial position.

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

Alternatively, 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 an energy storage structure 116. Specifically, the limiting structure 115 has opposite ends, one end of which abuts against the inner wall surface 131B, and the other end of which is connected with the energy storage structure 116. When the limit structure 115 is not engaged with the limit groove 131A, the limit structure 115 is in a compressed state under the action of the energy storage structure 116 to keep elastic abutment with the inner wall surface 131B of the end wall 1313, and the compression force in the energy storage state is greater than the restoring force of the elastic member, so as to limit the movement of the body 131. When the limit structure 115 is in a state of being clamped with the limit groove 131A, the limit structure 115 is still in a compressed state, and the limit structure 115 upwards moves a small distance to be clamped with the limit groove 131A, so that the compression force applied when the limit structure 115 is clamped with the limit groove 131A is smaller than that applied when the limit structure 115 is separated from the limit groove 131A. The energy storage structure is arranged on the limiting structure to effectively control the motion state of the body, so that the stability of the operation of the switch structure is further improved.

The following describes the specific process of the switch structure in the above embodiment briefly by combining the rotating device with a cylindrical shape, when the cooking device needs to be started to enter a heating working state, a user applies a rotating force on the knob, the whole rotating device rotates relative to the outer shell and drives the sliding block and the lever to move, so that the lever lifts the permanent magnet to the attraction of the temperature-sensing soft magnet until the temperature of the temperature-sensing soft magnet rises above a temperature threshold, the permanent magnet is separated from the temperature-sensing soft magnet to disconnect the heating circuit and drive the lever to move, and then the sliding block and the rotating shaft reversely slide and reversely rotate to reset, and in the resetting process, the action of the auxiliary force of the energy storage structure and the elastic piece can be received, so that the knob can reset to the state before the user rotating force is not acted.

In other embodiments, the body 131 may have other specific configurations. As shown in fig. 10 and 11, the body 131 includes an arc-shaped wall 133, a connecting body 134.

Specifically, as shown in fig. 11, the arc-shaped wall 133 is extended in the second direction and can serve as a guide wall surface for the rotation of the rotating device 13. Knob 1315 is fixedly attached to the outer side of arcuate wall 133. The knob 1315 is fixedly connected with the outer side surface of the arc wall 133 or integrally formed, and the knob 1315 can conveniently rotate the rotating device 13, so that the user can conveniently operate the rotating device. The connecting body 134 is fixedly connected to the inner side surface of the arc-shaped wall 133 and rotatably connected to the base 111, and the lever 1314 is fixedly connected to the connecting body 134. Specifically, the connecting body 134 may be an elongated rod body, and the extending direction of the length of the elongated rod body is substantially perpendicular to the extending direction of the arc-shaped wall 133. The connector 134 may be rotatably coupled to the base 111, and toggling the knob 1315 may rotate the connector 134 in a second direction relative to the base 111. The lever 1314 is fixedly connected to the connecting body 134 and disposed inside the inner side surface of the arc-shaped wall 133, and the lever 1314 may abut against the slider 12 in the first direction. Specifically, a lever 1314 is formed on a side of the connecting body 134, which is close to the slider 12, and the lever 1314 may be a long bar-shaped shaft, and a distance between a center of the connecting body 134 and a rotation center is smaller than a distance between an inner side surface of the arc-shaped wall 133 and the rotation center. The lever 1314 is capable of extending into the first throughbore 121 of the slider 12 and of moving within the first throughbore 121. The cross-sectional shape of the lever 1314 may be circular, rectangular, or any other shape, and the cross-section refers to a plane perpendicular to the direction in which the lever 1314 extends. In an exemplary embodiment, the cross-sectional shape of the lever 1314 is circular. Taking a forward motion state as an example, the lever 1314 rotates along with the rotation of the connecting body 134 until abutting 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. By arranging the rotation device as a rod-like member rotatable relative to the base, the flexibility of the arrangement of the rotation device structure 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, and 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 opposite ends, one end of which is fixedly connected to the inner side surface of the arc wall 133, and the other end of which 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 rotating device and the rotation of base and be connected, simple structure easily processes manufacturing.

Alternatively, as shown in fig. 11, an elastic member 114 is provided 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 rotating direction along with the movement of the connection body 134. The specific working process of the switch structure in this embodiment is as follows: the external force is applied to rotate the toggle knob 1315 clockwise, and drives the toggle lever 1314 to move to abut against the slider 12, so as to push the slider 12 to move downwards, thereby pressing the first end 141 of the lever 14, 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 in a state of attracting 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 cannot restore to the initial position after the external force is removed. After the temperature-sensitive soft magnet 71 reaches the curie temperature, the second end 142 of the lever 14 falls back under the action of gravity, and correspondingly the first end 141 of the lever 14 is rebound to lift up, so as to push the slide block 12 to move upwards, and the slide block 12 drives the rotating device 13 to rotate anticlockwise. Due to mechanical losses such as friction, the slider 12 is not able to return the rotating means 13 to the initial position completely, so that the rotating means 13 can be reset completely by providing a torsion spring. Through setting up the elastic component between connector and base, the rotatory process that is more convenient and effective.

In other embodiments, as shown in fig. 12, the outer side of the body 131 is provided with a cover 15, the cover 15 is fixedly connected with 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 notch 1521.

The inner diameter of the side wall 152 may be slightly larger than the distance between the arcuate wall 133 and the center of rotation so that the cover 15 may better cover the connector 134 and the arcuate wall 133 to protect these components. The end wall 151 may be used as an indication panel on which an indication lamp may be mounted, and the housing cavity may also be used for mounting a power supply circuit of the indication lamp. The arcuate wall 133 is disposed adjacent the side wall 152 and encloses a circumferential notch 1521, and the knob 1315 is rotatable within the circumferential notch 1521 in a second direction, with the connector 134 and the lever 1314 being adjacent the end wall 151. Specifically, a portion of the notch 1521 is formed in the side wall 152 along the circumferential direction, the length of the notch 1521 is greater than or equal to the length of the arc wall 133, and the knob 1315 is partially located outside the notch 1521, so that the notch 1521 can play a guiding role, and the knob 1315 can rotate along the notch 1521. By arranging the cover body, the cover body can protect part of components of the switch structure, so that the entry of dust or liquid is effectively reduced, and the service life of the switch structure is prolonged; and the notch arranged on the cover body can play a role in guiding the rotary motion of the knob, so that the convenience of use is improved.
