Furthermore, a rear cover 12 adjacent to the movable front cover 8 and capable of covering the first rotary driving mechanism 3 is further installed at a position of the machine body 1 corresponding to the first rotary driving mechanism 3, a movable supporting hook 81 is installed at an upper end of one side of the movable front cover 8 close to the rear cover 12, a supporting groove 121 is installed at a position of the rear cover 12 corresponding to the movable supporting hook 81, the movable supporting hook 81 is movably inserted into the supporting groove 121 and supported by the supporting groove 121 and can swing up and down relative to the supporting groove 121, an extending portion capable of extending into the rear cover 12 is installed at a position of one side of the movable front cover 8 close to the rear cover 12 lower than the movable supporting hook 81, an inclined top 82 extending upward is installed at an end of the extending portion, a trigger switch 100 (such as a microswitch) is installed at an inner side of the rear cover 12, the trigger switch 100 is electrically connected with a control system to control on and off of circuits of the first rotary driving mechanism 3, the second rotary driving mechanism 6 and the heating device 7 and the, the trigger part 101 of the trigger switch 100 is positioned above the inclined top 82, when the movable front cover 8 swings downwards around the supporting groove 121 to cover the pot body 4, the inclined top 82 upwards abuts against the trigger part 101 of the trigger switch 100, and a circuit between the first rotary driving mechanism 3, the second rotary driving mechanism 6 and the heating device 7 and a control system is connected, so that the control system can control the first rotary driving mechanism 3, the second rotary driving mechanism 6 and the heating device 7; when the movable front cover 8 swings up to the inclined top 82 and is separated from the trigger part 101 of the trigger switch 100, the circuits between the first rotary driving mechanism 3, the second rotary driving mechanism 6 and the heating device 7 and the control system are disconnected, so that the control system cannot control the first rotary driving mechanism 3, the second rotary driving mechanism 6 and the heating device 7 to work, and the safety protection effect is achieved.

In the present embodiment, the structure of the stirring head 5 has various embodiments, for example, the prior art is adopted. Of course, the structure shown in fig. 7 may be adopted. This stirring head 5 includes the main shaft 51 that the rotatory drive end of upper end and second rotary driving mechanism 6 links to each other, scrape axle 52 and the side that upwards extends from the tip of scraping axle 52 down from the lower extreme of main shaft 51 is scraped axle 53, after the stirring head stretched into the pot body, scrape axle 52 and press close to 4 diapalls of pot body down, in order to scrape the edible material of 4 diapalls of pot body, axle 53 and 4 inside walls of pot body are pressed close to the side, in order to scrape the edible material of 4 inside walls of pot body department, and the maximum diameter of the rotation orbit of scraping axle 53 of side is preferred to be greater than 4 internal radius of pot body, in order to guarantee that the edible material homoenergetic in the pot body 4 can receive. Specifically, during the stirring process, the side scraping shaft 53 continuously pushes the food material at the shaft edge outwards, the inner peripheral area of the side scraping shaft 53 is formed into a vacuum shape, a submerged vortex in the same direction as the stirring power is generated, liquid at the periphery or close to the water surface and light fixed are pumped to the inner peripheral area of the side scraping shaft 53 through the pumping force of the vortex, and then the liquid is pushed outwards by the side scraping shaft 53, and the three-dimensional stirring effect is formed in a circulating mode, so that the stirring uniformity is ensured.

Specifically, the distances between the lower scraping shaft 52 and the bottom wall of the pot body 4 and between the side scraping shaft 53 and the inner side wall of the pot body 4 are 0.1 ~ 3 mm, preferably less than 2 mm, so as to better scrape the food materials on the bottom wall and the inner side wall of the pot body 4, and particularly, the materials adhered to the inner side wall and the bottom wall of the pot body 4 can be peeled off in the half-cooked stage of the sticky food materials, so that the food materials are uniformly heated, and the condition of local coking is avoided.

In the embodiment of the present invention, as shown in fig. 7 to 10, the number and length of the lower scraping shafts 52 can be determined according to the stirring requirement. In an embodiment of the present invention, there are four lower scraping shafts 52, and four lower scraping shafts 52 are perpendicular to each other two by two. The number of the four lower scraping shafts 52 may be equal, or two opposite lower scraping shafts may be the same or different. For example, as shown in fig. 8, when the four lower scraping shafts 52 are the same in length and are opposite to each other two by two, the trajectory formed by the four side scraping shafts 53 in the working process is relatively sparse and is suitable for stirring and/or cooking soup, pasty and thin liquid food. As shown in fig. 9, two opposite lower scraping shafts 52 are equal in length and two adjacent lower scraping shafts are different in length, the four side scraping shafts 53 form a trajectory in the working process, and the trajectory density is medium, so that the four side scraping shafts are suitable for stirring and/or cooking water-boiling powdery food materials (such as cake food materials). As shown in fig. 10, two lower scraping shafts 52 are opposite and equal in length, and the other two lower scraping shafts are opposite but not equal in length, the four side scraping shafts 53 form a trajectory line in the working process, and the trajectory line density is high, so that the four side scraping shafts are suitable for stirring and/or cooking various food materials (such as western cake food materials).

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
