5. An automatic feeding device according to claim 4, wherein said one-way valve is configured to act under the pressure difference between said holding chamber and the outside, to switch from said closed state to said open state.

6. The automatic feeding device according to claim 5, wherein the one-way valve comprises a fixing part connected with the air inlet channel and a sealing part which is connected with the fixing part and made of elastic materials, the sealing part is provided with an air passing gap, and the air passing gap is switched from the closed state to the open state under the action of pressure difference between the material containing cavity and the outside and is switched from the open state to the closed state under the action of elasticity of the sealing part.

7. The automatic feeding device according to claim 1, wherein the storage bin comprises a bin body and a cover body sealing the bin body, the bin body and the cover body enclose to form the material containing cavity, and the air inlet channel is formed in the cover body.

8. The automatic feeding device according to claim 1, wherein a partition plate extending along an axial direction is arranged in the storage bin so as to divide the material containing cavity into a plurality of parts, and the air inlet channel is arranged above the partition plate, or the air inlet channel is provided with a plurality of parts and is arranged above each material containing cavity.

9. A food processor comprising the automatic feeding device according to any one of claims 1-8, further comprising a body and a pulverizing cup disposed in the body and having a pulverizing chamber, wherein the discharge tube is in communication with the pulverizing cup.

10. The food processor of claim 9 further comprising a blanking bin disposed above the pulverizing cup, the blanking bin having a blanking chamber communicable with the pulverizing chamber, and the blanking chamber being communicable with the suction device and the blanking tube, the blanking chamber being disconnectable from connection with the pulverizing chamber by the suction device and forming a negative pressure chamber to allow material to be sucked from the holding chamber into the blanking chamber.
