More specifically, the top of the stirring block 301 is placed in the front end 1011 of the support rod 101, and the bearing 107 is fixed to the stirring block 301 through the shaft retaining ring and the boss structure on the stirring block 301, and then the bearing 107 is fixed in the support rod 101 through the retaining ring of the inner hole of the front end 1011 of the support rod 101, so that the stirring block 301 is completely fixed; five pins 315 are arranged on the top of the stirring block 301, half of the pins 315 are stuck in the pin holes at the top of the stirring block 301, and the other half are stuck in the shaft holes of the five lower planetary gears 112 (see Figure 3 ). When the stirring main shaft 305 rotates, the two stirring blades 304 are rotated simultaneously through the bevel gear pair, and the stirring mechanism 3 completes the stirring action of the food through the stirring blades 304.

[0024] See Figure 2 , Figure 3When the motor 106 is started, the upper sun gear 110 on the output shaft of the motor 106 rotates, causing the five upper planetary gears 111 in the same gear pair to rotate. Since the five upper planetary gears 111 are sleeved on the upper shaft 1141 of the planetary gear mounting block 114, when the upper planetary gears 111 rotate, the planetary gear mounting block 114 will also be driven to rotate. Half of the shaft holes of the five lower planetary gears 112 are sleeved on the lower shaft 1142 of the planetary gear mounting block 114, so when the planetary gear mounting block 114 rotates, the five lower planetary gears 112 will also be driven to rotate. And because the other half of the shaft holes of the five lower planetary gears 112 are sleeved on the five pins 315 at the top of the stirring block 301, when the five lower planetary gears 112 rotate, the stirring block 301 will also be driven to rotate. The lower sun gear 113 meshes with the five lower planetary gears 112 . When the lower planetary gears 112 rotate, the lower sun gear 113 rotates. At the same time, because the sun gear 113 is connected to the stirring main shaft 305 , when the sun gear 113 rotates, the stirring main shaft 305 rotates simultaneously.

[0025] In this planetary gear mechanism, the upper sun gear 110 and the lower sun gear 113 both have 17 teeth, the upper planetary gear 111 and the lower planetary gear 112 both have 14 teeth, and the reduction gear ring 109 has 46 teeth. In this planetary gear mechanism, the reduction gear ring 109 is fixed, and the power is transmitted from the sun gear to the planetary gear. The transmission formula can be obtained as i=1+ZR / ZS, where i is the transmission ratio, ZR is the number of teeth of the gear ring, and ZS is the number of teeth of the sun gear. It can be obtained that the transmission ratio i=3.7, when the planetary gear rotates 1 circle along the reduction gear ring, the sun gear rotates 3.7 circles.

[0026] See Figure 1 , Figure 5 , Figure 6 The scraper mechanism 2 is installed on the stirring mechanism 3 to scrape the food that is not within the stirring range of the stirring mechanism 3 back into the stirring range, and includes a mounting block 201 connected to a protrusion 3011 on a stirring block 301, a hanging rod 202 provided on the mounting block 201, and a silicone scraper 204 provided at the front end of the hanging rod 202 through a scraper mounting plate 203. When the scraper mechanism 2 rotates, the silicone scraper 204 scrapes the food stuck to the edge of the pot into the pot for stirring.

[0027] When the utility model is used, the support mechanism 1 is fixed on the rotating shaft a of the swing motor of the cooking machine through the motor shaft fixing plate 104 (see Figure 2), by controlling the swing motor and the support mechanism 1 to drive the utility model to swing up and down in the pot, and the magnetic attraction 105 and the external sensor induction control the stop position of the utility model's up and down swing. When cooking, the utility model swings downward, starts the motor 106, and drives the upper sun gear 110, the upper planetary gear 111, the lower planetary gear 112, and the lower sun gear 113 to rotate through the planetary gear mechanism, so that the stirring block 301 and the stirring main shaft 305 rotate at different speeds. The stirring block 301 drives the scraping mechanism 2 and the gear mounting block 302 to rotate together, thereby forming a stirring mechanism revolution. The stirring main shaft 305 drives the stirring blade 304 on the driving shaft 313 to rotate and form self-rotation through the universal joint coupling 307, and the driving shaft 313 rotates the driven shaft 312 through the bevel gear pair, thereby driving the stirring blade 304 on the driven shaft 312 to rotate and form self-rotation, forming two stirring blades 304 that rotate while revolving.
