(1) In the present invention, by setting up a bottom scraping and mixing mechanism, the scraper on the outer wall of the mixing rod will be thrown out with the centrifugal force of the rotation of the mixing rod, causing the scraper to slide on the outer wall of the mixing rod and pull the elastic rope to deform, and the scraper will Slide the outer wall of the mixing rod, and slide and scrape the bottom of the outer wall of the mixing rod. The bottom of the outer wall of the mixing rod will scrape off the residue deposited and adhered to the bottom of the inner wall of the mixing box in real time, ensuring that the mixing rod deposits on the inner wall of the mixing box. While the residue is slidingly cleaned, it further improves the cleaning effect on the bottom of the inner wall of the mixing box, preventing a large amount of residue from adhering to the bottom of the inner wall of the mixing box during mixing, causing the food mixing effect to decrease.

(2) In the present invention, by setting up a bottom scraping and mixing mechanism, when the scraper slides on the outer wall of the stirring rod, the magnetic attraction between the scraper and the magnetic block on the outer wall of the opening and closing plate is carried out, so that the magnetic block drops closer to the mixing rod. scraper, and press the opening and closing plate to drive the rotating shaft to rotate and descend. As the scraper continues to slide, the magnet block and the connecting plate are opened and closed to slide on the outer wall of the fixed block. When the scraper slides away from the magnet block, the gap between the magnet block and the scraper is The magnetic attraction between them becomes smaller due to the distance until it is less than the elastic tension of the small elastic rope, so that the opening and closing plate is quickly pulled back by the small elastic rope, and the scraper is magnetically attracted to the next magnet block, thereby achieving continuous magnetic attraction to the magnet block. And disengage, realizing the reciprocating vibration opening and closing of the opening and closing plate.

(3) The present invention sets up a scraping, opening and closing agitation mechanism. When magnetically attracted to the magnetic block, the magnetic block drives the connecting plate to slide and rotate on the outer wall of the fixed block, thereby wiping and cleaning the outer wall of the opening and closing plate, ensuring that the opening and closing plate is The inside of the mixing box is opened and closed and vibrated for a long time to clean, which not only improves the uniformity of mixing inside the mixing box, but also minimizes the possibility of residues adhering to the outer wall of the opening and closing plate.

(4) In the present invention, a scraping, opening and closing agitation mechanism is provided. After the magnetic block is separated from the magnetic attraction between the scraper and the scraper, the opening and closing plate is pulled back by the small elastic rope, thereby performing a circular opening and closing movement, connecting the plate and the magnet. The blocks are quickly thrown out as the centrifugal force of the opening and closing plate opens and closes, and the outer wall of the opening and closing plate performs a opening and closing rotation and swing, which further improves the scraping and cleaning effect on the outer wall of the opening and closing plate, and improves the cleaning effect on the mixing box through the movement of the connecting plate.

Elastic rope 305. One end of the elastic rope 305 is fixedly connected to the outer wall of the rotating rod 301. The outer wall of the stirring rod 302 is rotationally connected to a rotating shaft 308. The outer wall of the rotating shaft 308 is fixedly connected to an opening and closing plate 307. The outer wall of the opening and closing plate 307 is provided with a magnetic block 306. The outer wall of the opening and closing plate 307 A small elastic rope 309 is fixedly connected, one end of the small elastic rope 309 is fixedly connected to the outer wall of the stirring rod 302, and a scraping opening and closing stirring mechanism 4 is provided outside the opening and closing plate 307;

The scraping, opening and closing stirring mechanism 4 includes a connecting plate 401. One end of the connecting plate 401 is fixedly connected to the outer wall of the magnet block 306. The other end of the connecting plate 401 is fixedly connected to a fixed block 402. One end of the fixed block 402 is rotationally connected to the outer wall of the opening and closing plate 307.

The scraping, opening and closing stirring mechanism 4 also includes a scraper block 403, the outer wall of the scraper block 403 is fixedly connected to the bottom of the opening and closing plate 307.

The magnetic properties of the opposite sides of the scraper 304 and the magnet block 306 are that opposite poles attract each other.

The outer wall of the scraping block 403 is triangular.

The magnetic attraction force between the scraper 304 and the magnet block 306 is greater than the elastic force of the small elastic rope 309 .

The scraper 304 has a trapezoidal shape.

A chute is provided on the outer wall of the scraper 304, and the outer wall of the scraper 304 is slidingly connected to the outer wall of the stirring rod 302 through the chute;

When in use, put the crushed food into the inside of the mixing box 2 through the inlet cover 5 on the top of the mixing box 2, and then start the motor 8 to drive the rotating rod 301 and the stirring rod 302 to rotate synchronously, water the food and mix it, so that The broken food is fully mixed with water to facilitate unified detection, and is released through the outlet cover 9 after the mixing is completed;

When the rotating rod 301 drives the stirring rod 302 to rotate and mix, the scraper 304 on the outer wall of the stirring rod 302 will be thrown out along with the centrifugal force of the rotation of the stirring rod 302, causing the scraper 304 to stir during mixing. The outer wall of the rod 302 slides and pulls the elastic rope 305 to deform. The scraper 304 slides on the outer wall of the mixing rod 302 and slides and scrapes the bottom of the outer wall of the mixing rod 302. The bottom of the outer wall of the mixing rod 302 is deposited and adhered to the bottom of the inner wall of the mixing box 2. The attached residue is scraped off in real time, ensuring that the stirring rod 302 slides and cleans the residue deposited on the inner wall of the mixing box 2, further improving the cleaning effect on the bottom of the inner wall of the mixing box 2, and preventing a large amount of residue from sticking during mixing. Attached to the bottom of the inner wall of the mixing box 2, the food mixing effect is reduced;

And when the scraper 304 slides on the outer wall of the stirring rod 302, magnetic attraction occurs through the magnetic attraction between the scraper 304 and the magnetic block 306 on the outer wall of the opening and closing plate 307, so that the magnetic block 306 drops close to the scraper 304 and presses The opening and closing plate 307 drives the rotating shaft 308 to rotate and descend. As the scraper 304 continues to slide, it drives the magnet block 306 and the connecting plate 401 to open, close and slide on the outer wall of the fixed block 402. When the scraper 304 slides away from the magnet block 306, the magnet block 306 and the connecting plate 401 slide. The magnetic attraction between the scrapers 304 becomes smaller due to the distance until it is less than the elastic pulling force of the small elastic rope 309, so the opening and closing plate 307 is quickly pulled back by the small elastic rope 309, and the scraper 304 is magnetically attracted to the next magnet block 306. As a result, the magnetic block 306 is continuously magnetically attracted to and separated from the magnetic block 306, and the opening and closing plate 307 is opened and closed with reciprocating vibration. The vibration of the opening and closing plate 307 will quickly push away the residue scraped from the outer wall of the stirring rod 302 to avoid the residue being scraped. If it falls around, it cannot be efficiently integrated into the mixture inside the mixing box 2, thereby achieving the effect of improving the mixing efficiency;

And when magnetically attracted to the magnetic block 306, the magnetic block 306 drives the connecting plate 401 to slide and rotate on the outer wall of the fixed block 402, thereby wiping and cleaning the outer wall of the opening and closing plate 307, ensuring that the opening and closing plate 307 cleans the inside of the mixing box 2 for a long time. The opening and closing vibration is clean, which not only improves the mixing uniformity inside the mixing box 2, but also avoids the residue adhering to the outer wall of the opening and closing plate 307 to the greatest extent;

When the scraper 304 drives the opening and closing plate 307 to press down through the magnetic attraction between the magnet blocks 306, the opening and closing plate 307 drives the rotating shaft 308 to rotate and press down, causing the scraping block 403 at the bottom of the opening and closing plate 307 to contact the outer wall of the scraper 304. and fit together, so that when the scraper 304 slides, the residue on the outer wall can be scraped off by the scraper 403. By continuously magnetically attracting each magnet block 306, the scraper 304 is constantly in contact with different scrapers 403 and Scraping, cleaning itself, avoids the problem that the scraping effect is reduced due to the accumulation of mixture on the outer wall of the scraper 304 for a long time, and it is difficult to clean.

After the magnetic block 306 breaks away from the magnetic attraction between the scraper 304, the opening and closing plate 307 is pulled back by the small elastic rope 309, thereby performing a circular opening and closing movement. The connecting plate 401 and the magnetic block 306 open and close with the opening and closing of the opening and closing plate 307. The centrifugal force is quickly thrown out, and the outer wall of the opening and closing plate 307 performs an opening and closing rotation and swing, which further improves the scraping and cleaning effect on the outer wall of the opening and closing plate 307, and improves the cleaning effect on the bottom area inside the mixing box 2 through the movement of the connecting plate 401. The blending effect of the mixture with the middle and upper layers.
