Referring to fig. 4, it can be appreciated that the lift lever 103 is provided with graduation marks 401. When the height of the heating element 301 of the related product is adjusted, the user cannot clearly know how much the heating element 301 is lifted, and therefore the user cannot intuitively know the position of the heating element 301 in the adjustment process, which results in lower efficiency of adjusting the height of the heating element 301. The cooking device provided by the scheme is provided with the scale marks 401 on the lifting rod 103, and in the adjustment process, a user can clearly know the lifting distance of the heating component 301 by observing the change of the scale marks 401, so that the efficiency of adjusting the height of the heating component 301 can be improved.

Referring to fig. 4, it can be understood that a pointer 402 is further disposed on the door body 102, the pointer 402 is located near the second through hole, and the pointer 402 is matched with the scale. By setting the pointer 402, a user can be given a more accurate reference point, and the specific scale value of the scale mark 401 is read by the indication of the pointer 402, so that the user can clearly and accurately grasp the lifting distance of the heating component 301.

Referring to fig. 5 to 8, it can be understood that the control assembly further includes a fixed seat 501 and a fixed bracket 502, the second power device includes a driving motor 505 and a driving element 506, and the driving motor 505 drives the locking tongue 507 through the driving element 506 to realize the back-and-forth telescopic motion. The fixing seat 501 is connected to the door body 102, the fixing bracket 502 is connected to the fixing seat 501, the driving motor 505 is mounted on the fixing bracket 502, and the driving motor 505 and the driving member 506 are respectively located at two opposite sides of the fixing bracket 502.

Referring to fig. 7, it will be appreciated that the actuating member 506 includes a first cam portion 604 for actuating the latch tongue 507. The driving motor 505 drives the first cam portion 604 to rotate, so that the first cam portion 604 periodically drives the lock tongue 507 to move, and the rotation of the first cam portion 604 drives the lock tongue 507 to make linear motion, thereby realizing the periodic back-and-forth telescopic motion of the lock tongue 507.

It can be understood that the second power device may also be an air cylinder or a linear motor, and the linear motion of the air cylinder or the linear motor drives the locking tongue 507 to make a linear motion, so as to realize the periodic back-and-forth telescopic motion of the locking tongue 507.

Referring to fig. 6 to 8, it can be understood that the control assembly includes a micro switch 601, the driving member 506 includes a second cam portion 605, the second cam portion 605 is disposed in the up-down direction with the first cam portion 604, and the second cam portion 605 is disposed alternately with the first cam portion 604, the micro switch 601 is disposed in the vicinity of the second cam portion 605, and the second cam portion 605 cooperates with the micro switch 601 to control the rotation of the driving motor 505. Specifically, the driving motor 505 drives the driving element 506 to rotate, when the second cam part 605 rotates to the micro switch 601, the first cam part 604 pushes the lock tongue 507, and the second cam part 605 contacts with the micro switch 601 to trigger the signal of the micro switch 601, the driving motor 505 stops rotating after receiving the signal of the micro switch 601, and then the driving element 506 stops rotating, at this moment, the lock tongue 507 is just far away from the lifting rod 103 and is separated from the limiting part 303, and the lifting rod 103 can freely move up and down, thereby realizing the lifting of the heating element 301.

As shown in fig. 5 to 8, it can be understood that the driver 506 includes a plurality of first cam portions 604 and a plurality of second cam portions 605, the plurality of first cam portions 604 are arranged at intervals in the circumferential direction, the plurality of second cam portions 605 are arranged at intervals in the circumferential direction, and each second cam portion 605 is located between adjacent two first cam portions 604 in the projection plane in the up-down direction. It will be appreciated that when a first cam portion 604 and a second cam portion 605 are provided, the driver 506 will need to rotate 360 ° in the same direction to begin the next cycle of control of the latch 507; when two first cam portions 604 and two second cam portions 605 are provided, if the two first cam portions 604 are arranged uniformly in the circumferential direction of the driver 506, the driver 506 needs to be rotated 180 ° in the same direction to start the control of the latch 507 for the next cycle. By analogy, the greater the number of first and

second cam portions

604, 605, the smaller the angle that the driver 506 needs to rotate to open the next cycle. Therefore, by providing the plurality of first cam portions 604 and the plurality of second cam portions 605, the rotation angle of the driving member 506 can be reduced, and the control of the next cycle can be realized, thereby saving time and improving the working efficiency.

Referring to fig. 5 to 8, it can be understood that the locking tongue 507 includes a third cam portion 602, and the third cam portion 602 cooperates with the first cam portion 604 to achieve effective control of the movement of the locking tongue 507. When the driving member 506 includes a plurality of first cam portions 604, the advantage of the cooperation between the plurality of first cam portions 604 and the third cam portion 602 is more obvious, that is, when the number of the first cam portions 604 is larger, the gap between two adjacent first cam portions 604 is smaller, and if the engaging surfaces of the locking tongue 507 and the driving member 506 are flat, the engaging surfaces of the locking tongue 507 and the driving member 506 may contact with the two first cam portions 604 at the same time at a certain time, which affects the control precision. By providing the third cam portion 602, the third cam portion 602 protrudes toward the driver 506, the area in the radial direction of the driver 506 is small, the possibility of simultaneous contact with the two first cam portions 604 is reduced, and the first cam portions 604 and the third cam portion 602 cooperate to increase the contact area and improve the smoothness of the movement.

Referring to fig. 5 to 8, it can be understood that the control assembly further includes a guide plate 503, the guide plate 503 is mounted on the fixing base 501, the guide plate 503 is provided with a guide groove 701 engaged with the locking tongue 507, the locking tongue 507 is disposed in the guide groove 701, and the guide groove 701 guides the telescopic movement of the locking tongue 507. Through setting up guide way 701 for the motion directionality of spring bolt 507 is more accurate, is difficult for rocking and skew track, and simultaneously, the spring bolt 507 motion is also more stable, guarantees that spring bolt 507 can accurately move to spacing portion 303, fixes lifter 103 at a certain height with spacing portion 303 cooperation.

Referring to fig. 5 to 8, it can be understood that the control assembly further includes a cover plate 504, the cover plate 504 is connected to the guide plate 503 and is located above the guide groove 701, and the cover plate 504 limits the displacement of the locking tongue 507 in the up-and-down direction, so as to prevent the locking tongue 507 from being separated from the guide groove 701, thereby ensuring the normal operation of the locking tongue 507.

Referring to fig. 7 and 8, it can be understood that the door 102 is provided with a first through hole 801 for accommodating the shift lever 603, the shift lever 603 is connected to the latch 507 in a threaded manner, and the latch 507 is driven to perform telescopic motion in the left-right direction by controlling the shift lever 603 to move in the left-right direction, so as to control the fixing of the lifting rod 103 or the releasing of the lifting rod 103. The driving lever 603 is sleeved with a covering piece 105 capable of covering the first through hole 801. The cover 105 is located at an outer side of the door body 102, and impurities capable of blocking dust are introduced into the door body 102 through the first through hole 801. Meanwhile, the surface area of the covering part 105 is large, so that the covering part is convenient for a user to grasp, and further convenient for the user to control.
