[0036] Next, the knob module 100 of the cooking device according to an embodiment of the present utility model will be described with reference to the accompanying drawings.

[0037] It should be noted that the cooking device 1000 is provided with a knob module 100, a main body 200 and a combustion structure (not shown in the figure). Gas can be introduced into the combustion structure. The main body 200 is provided with an ignition member 201, and the ignition member 201 is used to ignite the gas introduced into the combustion structure so that the combustion structure can emit heat outward. The knob module 100 is used to cooperate with the ignition member 201 so that the knob module 100 can control the ignition or shutdown of the ignition member 201.

[0038] As Figures 1 - 6As shown in the figure, the knob module 100 of the cooking device according to an embodiment of the present utility model includes: a knob 2, a fixed bracket 5, a display screen 41, and a pivot shaft 7. The knob 2 includes a body 21 and a mating portion 22. An accommodating cavity 211 is provided inside the body 21. One side of the accommodating cavity 211 is open, and the other side is provided with the mating portion 22 and a through hole 212.

[0039] Thus, an integrated design of the display screen 41 and the knob 2 can be achieved, which is beneficial to saving space, shortening the transmission path, improving the user's operation feel, reducing the failure rate of the knob module 100, and improving the reliability of the knob module 100.

[0040] First, as Figures 1 - 5 shown, the knob module 100 includes a knob 2 and a pivot shaft 7. The knob 2 includes a body 21 and a mating portion 22. The body 21 can be configured as a circle, a square, etc. for the user to hold. An accommodating cavity 211 is provided inside the body 21. One side of the accommodating cavity 211 facing away from the main body 200 is open, and the other side is provided with the mating portion 22 and a through hole 212. The through hole 212 is arranged around the mating portion 22.

[0041] The pivot shaft 7 is rotatably arranged on the main body 200. The side of the mating portion 22 facing the main body 200 is connected to the pivot shaft 7 to rotatably mount the knob 2 on the main body 200. Moreover, the pivot shaft 7 can also be connected to the ignition member 201, so that the knob 2 can drive the pivot shaft 7 to move, thereby controlling the ignition member 201.

[0042] Meanwhile, it can be set that the knob module 100 further includes a display module 4 and a fixed bracket 5. The display module 4 includes a display screen 41. The display screen 41 is located inside the accommodating cavity 211. The side of the display screen 41 facing away from the main body 200 forms a display area, which can be used to display the working information of the cooking device 1000, such as temperature, working duration, etc.

[0043] An installation protrusion 411 is provided on the side of the display screen 41 facing the main body 200. The fixed bracket 5 is arranged inside the accommodating cavity 211. The fixed bracket 5 is provided with an installation through hole 51. The installation protrusion 411 is used to be inserted into the installation through hole 51 to connect the display screen 41 and the fixed bracket 5. The fixed bracket 5 is arranged opposite to the through hole 212. One end of the fixed bracket 5 facing the main body 200 can extend out of the through hole 212 to the outside of the accommodating cavity 211 and be connected to the main body 200 to fix the display screen 41 on the main body 200.

[0044] It should be noted that the display screen 41 and the knob 2 are set to be relatively rotatable. When the knob 2 rotates relative to the main body 200, the display screen 41 and the main body 200 remain stationary. The through hole 212 is used to avoid the fixing bracket 5 to prevent interference between the fixing bracket 5 and the knob 2, thereby ensuring that the position of the display screen 41 can always remain unchanged for the user to view the display screen 41.

[0045] In the specific working process, when the knob 2 is in the closed position, the cooking device 1000 remains closed; when the cooking device 1000 needs to work, the user can press down and rotate the knob 2 to the open position. The cooking device 1000 can introduce gas into the combustion structure, and the igniter 201 can ignite the gas introduced into the combustion structure so that the combustion structure can radiate heat outward. At this time, the display screen 41 can be lit; after the gas is ignited, the user releases the knob 2, and the knob 2 resets upward, and the igniter 201 closes accordingly. At this time, gas continuously flows into the combustion structure so that the combustion structure can continuously radiate heat outward, and the display screen 41 remains lit; during the continuous operation of the combustion structure, the knob 2 can be rotated within the open position to adjust the gas intake in the combustion structure, thereby adjusting the firepower; then, after the cooking device 1000 finishes cooking, the user can rotate the knob 2 in the reverse direction to reset the knob 2 to the closed position, and the cooking device 1000 cuts off the gas supply so that the combustion structure stops working. At this time, the display screen 41 can be turned off.

[0046] It can be understood that by installing the display screen 41 in the containing cavity 211, an integrated design of the display screen 41 and the knob 2 can be realized, which is beneficial to saving space, and the main body 21 can be used to protect the display screen 41 to extend the service life of the display screen 41. In addition, by directly connecting the matching part 22 with the pivot shaft 7, the rotation axis of the matching part 22 can be made to coincide with the rotation axis of the pivot shaft 7, shortening the transmission path, reducing the force required for the user to rotate the knob 2, improving the user's operation feel, and reducing the failure rate of the knob module 100.

[0047] For the knob module 100 of the cooking device according to the embodiment of the present invention, by installing the display screen 41 in the containing cavity 211, an integrated design of the display screen 41 and the knob 2 can be realized, which is beneficial to saving space, and by directly connecting the matching part 22 with the pivot shaft 7, the transmission path can be shortened, the force required for the user to rotate the knob 2 can be reduced, the user's operation feel can be improved, the failure rate of the knob module 100 can also be reduced, and the reliability of the knob module 100 can be improved.

[0048] In some embodiments of the present invention, such as Figures 3 - 5As shown, the mating portion 22 is located in the middle of the accommodating cavity 211, and the mating portion 22 can be connected to the inner wall of the accommodating cavity 211 through the connecting arm 23. Exemplarily, the body 21 can be configured as an annular shape, the mating portion 22 is located at the center of the body 21, and the connecting arm 23 extends along the radial direction of the body 21 and is respectively connected to the mating portion 22 and the inner wall of the accommodating cavity 211 at both ends to fix the mating portion 22.

[0049] Through the above arrangement, the central axis and the rotation axis of the knob 2 can be made to coincide, so that the user can better control the rotation angle of the knob 2, improving the design rationality of the knob module 100.

[0050] In some embodiments of the present invention, as Figures 3 - 5 shown, the outer peripheral wall of the mating portion 22, the connecting arm 23 and the inner wall of the accommodating cavity 211 define a through hole 212. The through hole 212 is arranged around the mating portion 22 and extends along the rotation direction of the knob 2. Through the above arrangement, the size of the through hole 212 can be made larger to ensure that the fixing bracket 5 does not interfere with the inner wall of the through hole 212, improving the movement stability of the knob 2, and the forming difficulty of the through hole 212 can be reduced, and the processing difficulty of the knob 2 can be reduced.

[0051] In some embodiments of the present invention, as Figure 3 shown, the thickness of the connecting arm 23 can be set to be greater than the wall thickness of the body 21. Through the above arrangement, the connection strength between the mating portion 22 and the body 21 can be improved to improve the structural stability of the mating portion 22, so that the knob 2 can better drive the pivot shaft 7 to rotate, improving the reliability of the knob module 100.

[0052] In some embodiments of the present invention, as Figure 1 、 Figure 3 and Figure 5 shown, a mating groove 221 is provided in the mating portion 22. The mating groove 221 opens towards the main body 200. The cross-section of the mating groove 221 is configured as non-circular, such as oval, polygonal, irregular, etc. The pivot shaft 7 is matched with the mating groove 221. The pivot shaft 7 is used for plugging and mating with the mating groove 221 to connect the knob 2 with the pivot shaft 7, so that the knob 2 can drive the pivot shaft 7 to rotate.

[0053] Through the above arrangement, the connection difficulty between the knob 2 and the pivot shaft 7 can be reduced, and it can be ensured that relative rotation between the knob 2 and the pivot shaft 7 is not likely to occur, improving the design rationality of the knob module 100.

[0054] In some embodiments of the present utility model, the knob module 100 of the cooking device according to the embodiments of the present utility model further includes: a first bracket 1, a trigger member, and a switch member 42. The first bracket 1 is adapted to be mounted to the main body 200, and a pivot shaft 7 is rotatably provided on the first bracket 1; the trigger member is connected to the knob 2 to rotate synchronously with the knob 2; the switch member 42 is electrically connected to the display screen 41, and the trigger member is used to cooperate with the switch member 42 to control the opening and closing of the switch member 42 during rotation so that the display screen 41 is lit or turned off.

[0055] For example, referring to Figures 1 - 5 As shown, the knob module 100 includes a first bracket 1 and a trigger member. The first bracket 1 is adapted to be mounted on the main body 200, and a pivot shaft 7 is rotatably provided on the first bracket 1. The trigger member is sleeved on the pivot shaft 7 and connected to the knob 2 so that the trigger member can rotate synchronously with the knob 2. In this way, centralized installation of the knob module 100 can be achieved, which is beneficial to reducing the installation difficulty of the knob module 100.

[0056] Among them, the display module 4 further includes a switch member 42. The switch member 42 is electrically connected to the power supply and the display screen 41 respectively. The trigger member cooperates with the switch member 42, and the trigger member is used to control the opening and closing of the switch member 42 during rotation so that the switch member 42 can selectively electrically connect the display screen 41 to the power supply, thereby lighting or turning off the display screen 41.

[0057] In the specific working process, when the knob 2 is in the closed position, the cooking device 1000 remains closed; when the cooking device 1000 needs to work, the user can press down and rotate the knob 2 to the open position. The cooking device 1000 can introduce gas into the combustion structure, and the igniter 201 can ignite the gas introduced into the combustion structure so that the combustion structure can radiate heat outward. At this time, the trigger member can rotate with the knob 2 to control the switch member 42 to open, thereby lighting the display screen 41; after the gas is ignited, the user releases the knob 2, and the knob 2 resets upward, and the igniter 201 closes accordingly. At this time, gas can continuously flow into the combustion structure so that the combustion structure can continuously radiate heat outward, and the switch member 42 can remain in the open state to continuously light the display screen 41; during the continuous operation of the combustion structure, the knob 2 can be rotated within the open position to adjust the gas intake in the combustion structure, thereby adjusting the firepower; then, after the cooking device 1000 finishes cooking, the user can rotate the knob 2 in the reverse direction to reset the knob 2 to the closed position, and the cooking device 1000 cuts off the gas supply so that the combustion structure stops working, and the trigger member rotates to close the switch member 42, thereby turning off the display screen 41.

[0058] It can be understood that by setting the trigger member to rotate synchronously with the knob 2, so that the trigger member can turn on and off the display screen 41 when it rotates, the display screen 41 and the knob 2 can be linked, and there is no need to control the display screen 41 separately, which effectively avoids the situation where the user forgets to turn on or off the display screen 41, thereby improving the operating convenience of the cooking device 1000.

[0059] In some embodiments of the present invention, Figure 2 As shown, in a direction perpendicular to the rotation axis of the pivot shaft 7 , the trigger member and the switch member 42 are arranged side by side, and the trigger member rotates to contact or separate from the switch member 42 .

[0060] For example, when the knob 2 is in the closed position, the trigger is separated from the switch 42, the switch 42 is closed, and the display screen 41 remains closed; when the knob 2 is rotated and rotated to the open position, the trigger contacts the switch 42 to open the switch 42, and the display screen 41 lights up; and when the knob 2 is rotated to the closed position again, the trigger can be separated from the switch 42 to close the switch 42, thereby closing the display screen 41. Of course, the switch 42 can also be set to open when separated from the trigger, and closed when contacted with the trigger, and the utility model does not limit this.

[0061] Through the above arrangement, the structural complexity of the knob module 100 can be reduced, the switching stability of the switch element 42 can be improved, and the reliability of the knob module 100 is improved.

[0062] In some embodiments of the present invention, Figure 2 and Figure 6 As shown, the triggering member can be formed as a cam 3, and a notch 31 is provided on the outer peripheral wall of the cam 3. When the notch 31 is directly opposite to the switch member 42, the triggering member can be separated from the switch member 42, and when the notch 31 is staggered from the switch member 42, the triggering member can contact the switch member 42. In this way, the structure of the knob module 100 can be simplified, and the processing difficulty of the knob module 100 can be reduced.

[0063] In some embodiments of the present invention, Figure 2 As shown, the switch member 42 is disposed on the first bracket 1, and for example, the switch member 42 can be mounted on the first bracket 1 through the switch bracket 7. It can be understood that by arranging both the switch member 42 and the knob 2 on the first bracket 1, the integration of the knob module 100 can be improved, the installation difficulty of the knob module 100 can be reduced, and the relative stability between the switch member 42 and the knob 2 can be improved, so as to improve the switching stability of the switch member 42, thereby improving the reliability of the knob module 100.

[0064] The utility model also provides a cooking device 1000 .

[0066] For the cooking device 1000 according to an embodiment of the present invention, by mounting the display screen 41 in the containing cavity 211, an integrated design of the display screen 41 and the knob 2 can be realized, which is beneficial to saving space. And by directly connecting the engaging portion 22 with the pivot shaft 7, the transmission path can be shortened, the force required for the user to rotate the knob 2 can be reduced, the operation feel of the user is improved, the failure rate of the knob module 100 can be reduced, the reliability of the knob module 100 is improved, and it is beneficial to improving the overall performance of the cooking device 1000.

[0067] In some embodiments of the present invention, as shown Figures 1 - 2 in FIG. Figures 1 - 2 , the main body 200 is provided with a control panel 202, and the knob module 100 is arranged on the control panel 202. Thus, the knob module 100 can be integrated onto the control panel 202, making the cooking device 1000 easier to operate and improving the design rationality of the cooking device 1000.

[0068] In some embodiments of the present invention, as shown Figures 1 - 2 in FIG. Figures 1 - 2 , the knob 2 and the display screen 41 are located on one side of the control panel 202, and the ignition component 201 and the first bracket 1 are located on the other side of the control panel 202.
