## Abstract

A food heating device contain: a cup and a base used to hold the cup and including a transmission mechanism. The cup includes plural ribs mounted around an inner wall thereof, and each rib extends downwardly along the inner wall of the cup. The cup also includes plural protrusions fixed on a bottom end thereof and a shaft secured at a central position of the bottom end thereof. The shaft has a blade disposed on a top end thereof, such that the shaft is inserted through the bottom end of the cup and is connected with a transmission mechanism via a bearing. Thereby, ingredients are crushed into juices after the transmission mechanism drives the blade, and during a crushing process, the shaft nibs with the bearing to produce a high temperature, and the ingredients are crashed in the cup by the plural ribs and the protrusions to be heated quickly.

## Claims

### Claim 1

A food heating device comprising:
a cup;
a base used to hold the cup and including a transmission mechanism;
wherein the cup includes a plurality of ribs mounted around an inner wall thereof, and each rib extends downwardly along the inner wall of the cup;
wherein the cup also includes a plurality of protrusions fixed on a bottom end thereof and a shaft secured at a central position of the bottom end thereof, and the shaft has a blade disposed on a top end thereof, such that the shaft is inserted through the bottom end of the cup and is connected with a transmission mechanism via a bearing;
thereby, ingredients are crushed into juices after the transmission mechanism drives the blade, and during a crushing process, the shaft nibs with the bearing to produce a high temperature, and the ingredients are crashed in the cup by the plurality of ribs and the protrusions to be heated quickly.

### Claim 2 (depends on 1)

The food heating device as claimed in claim 1, wherein the shaft is inserted through the bottom end of the cup and a bearing and is connected with a first toothed member under the bearing, and the transmission mechanism of the base has a second toothed member mounted thereon for meshing with the first toothed member, such that the transmission mechanism drives the shaft to rotate and then drives the blade to rotate rapidly.

### Claim 3 (depends on 1)

The food heating device as claimed in claim 1, wherein each protrusion is formed in a sharp cone shape.

### Claim 4 (depends on 1)

The food heating device as claimed in claim 1, wherein the transmission device of the base is a motor.

### Claim 5 (depends on 1)

The food heating device as claimed in claim 1, wherein the plurality of ribs are equidistantly mounted around the inner wall of the cup and are spaced apart from each other.

### Claim 6 (depends on 1)

The food heating device as claimed in claim 1, wherein each protrusion is defined between two ribs.
