[0017] 1. The portion of the circuit board in the utility model located between the two response elements is provided with an avoidance gap, and the projection of the lever on the circuit board is completely located within the avoidance gap. In this way, no matter which one of the circuit board and the lever is installed first, it will not affect the other one, that is, it will not interfere with the later installed parts, thereby lowering the requirements for the assembly sequence of the two and facilitating the assembly of workers. In addition, by providing the avoidance gap on the circuit board to avoid the projection of the lever on the circuit board, the lever can pass through the avoidance gap during assembly, thereby preventing the lever from interfering with the circuit board, thereby reducing the processing accuracy requirements for the circuit board and the lever and the assembly accuracy requirements for the two, thereby reducing the manufacturing cost of the cooking appliance.

[0018] 2. The housing includes a base and an upper cover. The circuit board is mounted on the base, and the lever is mounted on the upper cover. When the upper cover and the base are assembled, the lever is assembled under the circuit board through the avoidance notch. With this design, during assembly, the assembly of the lever and the upper cover, and the assembly of the circuit board and the base can be carried out simultaneously at two assembly stations. Then, the base and the upper cover are assembled so that the lever can be assembled under the circuit board through the avoidance notch, thereby improving the assembly efficiency of the product. In addition, by using the space under the circuit board to accommodate the lever, the overall height of the housing can be reduced, making the product thinner and lighter.

[0019] 3. The response element is a Hall element, and a magnet is provided at the trigger end. When the trigger end drives the magnet to swing into the sensing area of ​​the Hall element, the Hall element is triggered by the magnetic field around the magnet and sends out a corresponding sensing signal in response. With this design, the trigger end triggers the response element without the need for the two to contact, and the spatial layout between components is more flexible and convenient, which facilitates product assembly; in addition, since the trigger end and the response element do not need to contact, interference and obstruction to the swing of the lever can be prevented, the operation feel is better, component damage is less, and the service life is longer.

[0020] 4. The lever comprises a first lever section that passes through the shell and a second lever section that is completely located in the shell. The end of the first lever section that is exposed outside the shell forms an operating end. The end of the first lever section that is located in the shell is connected to the second lever section to drive the second lever section to swing. The end of the second lever section that is away from the first lever section forms a trigger end. With such a design, the size of the portion where the second lever section is connected to the first lever section can exceed the size of the hole on the shell through which the first lever section passes, so as to reduce the size restriction on the portion where the second lever section is connected to the first lever section, thereby reducing the processing requirements for the size of the portion where the second lever section is connected to the first lever section; in addition, the lever is designed to consist of the first lever section and the second lever section, so that the structures of the two lever sections can be designed as needed to meet different design requirements, and the processing difficulty of the lever is also reduced.

[0021] 5. The second lever section includes a first lever sleeve and a second lever sleeve, which are buckled together to enclose a mounting cavity for accommodating the magnet. Such a design can protect the magnet to prevent the magnet from falling off, thereby ensuring the installation reliability of the magnet.

[0022] 6. One end of the first lever segment located in the housing is inserted into the installation cavity. One of the wall of the installation cavity and the end of the first lever segment is provided with a transmission column, and the other is provided with a transmission hole. The transmission column and the transmission hole are plugged and matched, so that the first lever segment drives the second lever segment to swing. With this design, the linkage of the first lever segment and the second lever segment can be achieved through the cooperation of the transmission column and the transmission hole, without the need for screw connection between the two, thereby simplifying the assembly of the first lever segment and the second lever segment.

[0023] 7. The lever is arranged to pass through the avoidance gap so that the two side walls of the avoidance gap limit the swing angle of the lever. This design can effectively limit the lever to swing only within a certain area, ensuring the safety of the lever and the response element. In particular, for the response element that needs to be touched to be triggered, this design can ensure that the lever can only touch the response element without damaging the response element.

[0024] 8. The response element is a micro switch, which includes an action reed. The trigger end presses the action reed to trigger the micro switch. The micro switch has sensitive detection accuracy and can accurately detect the touch or release action of the trigger end of the lever. It can respond to the touch or release action of the trigger end by sending a response signal to convert the swing action of the lever into an electrical control signal. In addition, the micro switch has a simple structure and a low price, which is conducive to simplifying the internal structure of the cooking appliance and reducing the production cost of the cooking appliance.

[0025] 9. A fixing plate is installed in the housing, and a fixing shaft and a torsion spring sleeved on the fixing shaft are provided on the fixing plate. The lever is rotatably sleeved on the fixing shaft, and the operating end and the triggering end are located on both sides of the fixing shaft. The torsion spring is used to drive the lever to swing in the opposite direction and reset after the lever swings and triggers one of the response elements. With this design, the lever can be swingably installed on the housing, and at the same time, when there is no external force on the operating end, the lever can be automatically reset by using the elastic reset of the torsion spring, without the user having to reversely toggle the lever, thereby improving user operability.

[0026] 10. The operation terminal is a resin ball, and the surface of the resin ball is electroplated with a metal layer. This design can not only improve the touch feel of the operation terminal, but also make the operation terminal have a metallic texture to improve the appearance of the operation terminal.

[Specific implementation method]

[0038] The utility model provides a cooking utensil, comprising a shell, a circuit board arranged transversely in the shell, and a lever capable of swinging relative to the shell, wherein one end of the lever is located outside the shell to form an operating end, and the other end is located inside the shell to form a triggering end, the circuit board has two response elements arranged opposite to each other and located on both sides of the triggering end, the triggering end is driven to swing by shifting the operating end, so that the triggering end triggers one of the response elements, an avoidance gap is provided at a portion of the circuit board located between the two response elements, and the projection of the lever on the circuit board is entirely located within the avoidance gap.

[0039] The portion of the circuit board in the utility model located between the two response elements is provided with an avoidance gap, and the projection of the lever on the circuit board is entirely located within the avoidance gap, so that no matter which of the circuit board or the lever is installed first, it will not affect the other one, that is, it will not interfere with the later installed parts, thereby requiring a lower assembly sequence for the two, and facilitating assembly by workers; in addition, by providing an avoidance gap on the circuit board to avoid the projection portion of the lever on the circuit board, the lever can pass through the avoidance gap during assembly, thereby preventing the lever from interfering with the circuit board, thereby reducing the requirements for the processing accuracy of the circuit board and the lever and the assembly accuracy of the two, thereby reducing the manufacturing cost of the cooking appliance.

[0040] The technical scheme of the embodiment of the utility model is explained and illustrated below in conjunction with the drawings of the embodiment of the utility model, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without making creative work all belong to the protection scope of the utility model. In addition, it should be understood that the following words indicating orientation or position relationship such as "up", "down", "left", "right", "longitudinal", "lateral", "inside", "outside", "vertical", "horizontal", "top", "bottom", etc. are only based on the orientation or position relationship shown in the drawings, only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0041] Reference Figures 1 to 7As shown, the cooking appliance in this embodiment can be an induction cooker, an electric ceramic cooker, etc. Taking the electric ceramic cooker as an example, it includes a shell 100, a circuit board 200 arranged horizontally in the shell 100, and a lever 300 that can swing relative to the shell 100, wherein the circuit board 200 is electrically connected to the control board 700, and the control board 700 is connected to the heating plate in the shell 100, and one end of the lever 300 is located outside the shell 100 to form an operating end 301, and the other end is located in the shell 100 to form a triggering end 302. The circuit board 200 has two response elements 210 arranged opposite to each other and located on both sides of the triggering end 302. The operating end 301 is moved to drive the triggering end 302 to swing, so that the triggering end 302 triggers one of the response elements 210, and the control board 700 controls the heating power or the start and stop of the heating plate according to the induction signal of the response element 210. When assembling the electric ceramic stove, the circuit board 200 and the lever 300 are assembled successively. Since the projection of the lever 300 on the horizontal plane is located within the projection of the circuit board 200 on the horizontal plane, and there are machining errors and assembly errors of the parts, the lever 300 may interfere with the circuit board 200 after assembly, which may cause the lever 300 to be unable to swing or even damage the circuit board 200. In order to avoid the above situation, the machining accuracy and assembly accuracy of the circuit board 200 and the lever 300 need to be ensured, which increases the manufacturing cost of the cooking appliance.

[0042] In order to reduce manufacturing costs and avoid interference between the lever 300 and the circuit board 200, the portion of the circuit board 200 located between the two response elements 210 in this embodiment is provided with an avoidance notch 220, and the projection of the lever 300 on the circuit board 200 is completely located within the avoidance notch 220. In this way, no matter which of the circuit board 200 and the lever 300 is installed first, it will not affect the other installed later, that is, it will not interfere with the later installed parts, thereby requiring a lower assembly sequence for the two, and facilitating assembly for workers; in addition, by providing the avoidance notch 220 on the circuit board 200 to avoid the projection of the lever 300 on the circuit board 200, the lever 300 can pass through the avoidance notch 220 during assembly, thereby preventing the lever 300 from interfering with the circuit board 200, thereby reducing the processing accuracy requirements for the circuit board 200 and the lever 300 and the assembly accuracy requirements for the two, thereby reducing the manufacturing cost of the cooking appliance.

[0043] Specifically, Figure 3 and 4As shown, the response element 210 in this embodiment is a Hall element. Two response elements 210 are installed on the bottom surface of the circuit board 200, and the trigger end 302 is provided with a magnet 400. When the trigger end 302 drives the magnet 400 to swing into the sensing area of ​​the Hall element, the Hall element is triggered by the magnetic field around the magnet 400 and sends a corresponding sensing signal to respond, thereby realizing the function of adjusting the heating power or starting the heating plate. For example: triggering the Hall element on the left can reduce the heating power, and triggering the Hall element on the right can increase the heating power, or triggering the Hall element on the right to increase the heating power, and triggering the Hall element on the left can reduce the heating power; or triggering the Hall element heating plate on the left to stop working, and triggering the Hall element heating plate on the right to start working. Further, when the lever 300 triggers the response element 210 once, a one-time gear adjustment of the heating plate can be realized; when the lever 300 triggers the response element 210 for a long time, continuous gear adjustment of the heating plate can be realized. Therefore, based on the different toggle parameters such as the number of triggers, the trigger duration or the trigger frequency, the same response element 210 can make different responses, and then the control board 700 can make different adjustments and controls on the working state of the heating plate according to the different responses issued by the same response element; in addition, the use of the Hall element as the response element 210 can make the trigger end 302 trigger the response element 210 without the need for the two to contact, and the spatial layout between the components is more flexible and convenient, which is convenient for product assembly; in addition, since the trigger end 302 and the response element 210 do not need to contact, it can prevent interference and obstruction to the swing of the toggle lever 300, and the operation feel is better, the damage to the components is less, and the service life is longer.

[0044] In order to enable the trigger end 302 to trigger the Hall element more sensitively, the trigger end 302 in this embodiment is located below the circuit board 200, and the shell 100 includes a base 110 and an upper cover 120, the upper cover 120 includes an annular upper cover frame 121 and a panel 122 installed on the top of the upper cover frame 121, and a strip-shaped through hole is provided on the front side wall of the upper cover frame 121, and the lever 300 passes through the through hole and is rotatably installed on the upper cover frame 121 to realize the swing of the lever 300 relative to the upper cover 120, and the two ends of the through hole can limit the swing angle of the lever 300. The bottom wall of the base 110 is provided with a screw column extending upward, and the four corners of the circuit board 200 are supported on the screw column and fixed on the screw column by screws, so that the circuit board 200 is installed on the base 110, and the avoidance gap 220 is provided on the side of the circuit board 200 close to the front side wall of the upper cover frame 121 and extends inwardly, and the avoidance gap 220 is located between the two screw columns, and the width of the avoidance gap 220 is greater than the width of the lever 300, and the distance between the closed end of the avoidance gap 220 and the front side wall of the upper cover frame 121 is greater than the distance between the trigger end 302 and the front side wall of the upper cover frame 121. In this way, when the upper cover 120 and the base 110 are assembled, the lever 300 can be smoothly assembled to the bottom of the circuit board 200 through the avoidance gap 220. After the shell 100 is assembled, the projection of the lever 300 on the circuit board 200 is all located in the avoidance gap 220. With such a design, during assembly, the assembly of the lever 300 and the upper cover 120, and the assembly of the circuit board 200 and the base 110 can be carried out simultaneously at two assembly stations, and then the base 110 and the upper cover 120 are assembled, so that the lever 300 can be assembled under the circuit board 200 through the avoidance gap 220, thereby improving the assembly efficiency of the product; in addition, by using the space under the circuit board 200 to accommodate the lever 300, the overall height of the shell 100 can also be reduced, so as to make the product lighter and thinner.

[0045] In addition, if Figures 5 to 7As shown, the lever 300 in this embodiment includes a first lever segment 310 and a second lever segment 320 which are separately formed, wherein the first lever segment 310 is arranged to penetrate the upper cover frame 121, and the end of the first lever segment 310 exposed outside the shell 100 forms an operating end 301, and the second lever segment 320 is entirely located inside the shell 100, and the end of the first lever segment 310 located inside the shell 100 is connected to the second lever segment 320 to drive the second lever segment 320 to swing, and the end of the second lever segment 320 away from the first lever segment 310 forms a trigger end 302. With such a design, the size of the portion where the second lever segment 320 and the first lever segment 310 are connected can exceed the size of the through hole on the upper cover frame 121 through which the first lever segment 310 passes, so as to reduce the size restriction on the portion where the second lever segment 320 and the first lever segment 310 are connected, thereby reducing the processing requirements for the size of the portion where the second lever segment 320 and the first lever segment 310 are connected; in addition, by designing the lever 300 to be composed of the first lever segment 310 and the second lever segment 320, the structures of the two lever segments can be designed as needed to meet different design requirements, while also reducing the processing difficulty of the lever 300.

[0046] Preferably, the first lever section 310 in this embodiment is a solid rod-shaped plastic part, and one end of the first lever section 310 located outside the housing 100 is a resin ball, the outer diameter of the resin ball is larger than the diameter of the perforation, and the resin ball forms the operating end 301, and the surface of the resin ball is electroplated with a metal layer. Such a design can not only improve the touch feel of the operating end 301, but also make the operating end 301 have a metallic texture, so as to improve the appearance of the operating end 301.

[0047] The second lever section 320 includes a first lever sleeve 321 and a second lever sleeve 322 which are formed separately. The first lever sleeve 321 and the second lever sleeve 322 are made of nylon glass fiber material to increase the structural strength and wear resistance of the first lever sleeve 321 and the second lever sleeve 322. The first lever sleeve 321 is provided with a buckle 3210 extending downward, and the second lever sleeve 322 is provided with a snap-on hole 3220. The first lever sleeve 321 and the second lever sleeve 322 are snap-on-locked with the buckle 3210 and the snap-on hole 3220 to form an installation cavity. The magnet 400 is bonded or embedded in the installation cavity corresponding to the trigger end 302. Such a design can protect the magnet 400 to prevent the magnet 400 from falling off, thereby ensuring the installation reliability of the magnet 400.

[0048] It is understandable that in other embodiments of the present invention, the snap-in hole may be provided on the first lever sleeve, and the buckle may be provided on the second lever sleeve; or, the first lever sleeve and the second lever sleeve may be fixed by bonding to enclose and form the installation cavity.

[0049] It is understandable that in other embodiments of the present invention, the second lever segment may also be a solid rod-shaped structure, the magnet is bonded and fixed to the outer side of the second lever segment, and the first lever segment and the second lever segment are fixedly connected by screws.

[0050] In order to realize the connection between the first lever segment 310 and the second lever segment 320, in this embodiment, one end of the first lever segment 310 located in the housing 100 is inserted into the installation cavity, and two transmission columns 323 are provided on the bottom wall of the installation cavity, that is, two transmission columns 323 extending upward are provided at one end of the second lever sleeve 322 away from the trigger end 302, and the two transmission columns 323 are spaced apart along the length direction of the second lever segment 320, and two transmission holes 311 are provided at one end of the corresponding first lever segment 310 located in the housing 100, and the transmission columns 323 are plugged and matched with the transmission holes 311, so that the first lever segment 310 drives the second lever segment 320 to swing. With such a design, the linkage between the first lever segment 310 and the second lever segment 320 can be realized by matching the transmission columns 323 with the transmission holes 311, without the need for screw connection between the two, thereby simplifying the assembly of the first lever segment 310 and the second lever segment 320.

[0051] In order to enable the lever 300 to swing relative to the upper cover frame 121 , a fixing plate 500 is further installed in the housing 100 in this embodiment. The fixing plate 500 is made of nylon glass fiber material to increase the structural strength and wear resistance of the fixing plate 500 . The upper cover frame 121 is also provided with two screw columns extending downward, and the two ends of the fixing plate 500 are fixed to the bottom surfaces of the screw columns by screws. The fixing plate 500 is provided with an integrally formed fixing shaft 510 and a torsion spring 600 sleeved on the fixing shaft 510. The fixing shaft 510 is formed by extending upward, and the operating end 301 and the trigger end 302 are located at the front and rear sides of the fixing shaft 510. The first lever sleeve 321 is provided with a first matching hole 3211, and the second lever sleeve 322 is provided with a second matching hole 3221. The second matching hole 3221 is located between the two transmission columns 323. The end of the first lever section 310 located in the shell 100 is provided with a third matching hole 312. The first matching hole 3211, the second matching hole 3221 and the third matching hole 312 are all rotatably matched with the fixing shaft 510, so as to realize that the lever 300 is rotatably sleeved on the fixing shaft 510, and then realize that the lever 300 is rotatably installed on the shell 100. One end of the torsion spring 600 is connected to the fixing plate 500, and the other end is connected to the second lever sleeve 322. In this way, after the lever 300 is swung to trigger one of the response elements 210, the torsion spring 600 will be deformed. In the absence of external force on the operating end 301, the elastic reset of the torsion spring 600 can be utilized to make the lever 300 swing in the opposite direction to achieve automatic reset, without the need for the user to reversely swipe the lever 300, thereby improving user operability.

[0052] It can be understood that in other embodiments of the present invention, the transmission column can also be arranged on the first lever sleeve; or the first lever sleeve and the second lever sleeve are both provided with transmission holes, and one end of the first lever section located in the shell is provided with a transmission rod, one end of the transmission rod upwardly penetrates the transmission hole on the first lever sleeve, and the other end downwardly penetrates the transmission hole on the second lever sleeve.

[0053] It is understandable that in other embodiments of the utility model, the response element can also be a micro switch, and two micro switches are installed on the front of the circuit board. At this time, the trigger ends of the lever are all located above the substrate of the circuit board and swing back and forth above the substrate of the circuit board.

The micro switch has sensitive detection accuracy, can accurately detect the touch or release action of the trigger end of the lever, and can respond to the touch or release action of the trigger end by sending a response signal to convert the swing action of the lever into an electrical control signal; in addition, the micro switch has a simple structure and a low price, which is conducive to simplifying the internal structure of the cooking appliance and reducing the production cost of the cooking appliance.

[0054] It is understandable that in other embodiments of the present invention, the lever can also be a solid integral piece, and the size of the trigger end on the lever does not exceed the size of the perforation on the upper cover frame, so that the trigger end can enter the upper cover frame through the perforation, and the lever is provided with a through hole that rotates with the fixed shaft.

[0056] Different from the first embodiment, when a micro switch is used as a response element and installed on the front of the circuit board, the lever can also extend downward and pass through the avoidance gap, so that the two side walls of the avoidance gap limit the swing angle of the lever. Such a design can effectively limit the lever to swing only within a certain area, ensuring the safety of the lever and the response element. Especially for a micro switch that needs to be touched to be triggered, such a design can make the lever only touch the response element without damaging the response element.

[0057] Embodiment 3

[0058] Different from the first and second embodiments, the fixing plate in this embodiment is installed on the base, the corresponding lever is rotatably installed on the base through the fixing plate, and the circuit board is installed on the upper cover frame through screws. After the upper cover and the base are assembled, the lever can be located below the circuit board or above the circuit board or pass through the avoidance gap. The specific structure of the lever and the way of cooperating with the fixing plate can refer to the setting of the first embodiment and will not be described in detail here.

[0059] It is understandable that in other embodiments of the present invention, the lever can also be rotatably mounted on the upper cover frame via a fixing plate, and the circuit board can be mounted on the upper cover frame via screws; or, the lever can be rotatably mounted on the base via a fixing plate, and the circuit board can be mounted on the base via screws. In the above two cases, the avoidance notch design can also be used to prevent interference between the lever and the circuit board after assembly, thereby reducing the processing accuracy requirements for the circuit board and the lever and the assembly accuracy requirements for the two, thereby reducing the manufacturing cost of the cooking appliance.

[0060] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
