Abstract

The present disclosure provides a drive assembly and a food processor. The drive assembly comprises: a drive body; and a transmission assembly comprising at least a first transmission member and a second transmission member, the first transmission member being in driving connection with the drive body and provided thereon with a first drive shaft, and the second transmission member being in driving connection with the drive body and provided thereon with a second drive shaft. The technical solution is capable of driving, using a single drive body, at least two drive shafts to move, so that multi-shaft output with a single drive body can be realized.

First claim

What is claimed is:

1. A food processor, comprising:
a drive assembly which comprises a drive body and a transmission assembly comprising at least a first transmission member and a second transmission member, the first transmission member being in driving connection with the drive body and provided thereon with a first drive shaft, and the second transmission member being in driving connection with the drive body and provided thereon with a second drive shaft;
a host assembly comprising the drive assembly;
a barrel body assembly installed on the host assembly and comprising:
a feed inlet;
a first barrel body communicating with the feed inlet;
a second barrel body communicating with the first barrel body through a communication port;
a smashing device that is arranged in the first barrel body, is in driving connection with the first drive shaft of the drive assembly and is rotated under the driving of the first drive shaft; and
a squeezing device that is arranged in the second barrel body, is in driving connection with the second drive shaft of the drive assembly and is rotated under the driving of the second drive shaft,
wherein when rotating, the smashing device is capable of cooperating with an inner side wall of the first barrel body to smash food entering the first barrel body from the feed inlet, and the smashed food enters, under the effect of the smashing device, the second barrel body through the communication port and is squeezed by the squeezing device in the second barrel body to achieve separation between juice and food residues.

2. The food processor according to claim 1 , further comprising:
a juice discharge opening arranged on the second barrel body, wherein after the separation between juice and food residues, the food juice is discharged through the juice discharge opening; and
a residue discharge opening arranged on the second barrel body, wherein after the separation between juice and food residues, the food residues are discharged through the residue discharge opening.

3. The food processor according to claim 1 , wherein
the smashing device is a grinding spiral head or a cutter, and the squeezing device is a squeezing screw rod.

4. The food processor according to claim 1 , wherein
the drive body is a motor comprising a motor shaft, the first transmission member is in driving connection with the motor shaft, and the second transmission member is in driving connection with the first transmission member.

5. The food processor according to claim 1 , wherein the first drive shaft and the second drive shaft are arranged to form a preset angle β, and
wherein the value of the preset angle β is more than or equal to 60° and less than or equal to 135°.

6. The food processor according to claim 1 , wherein the rotational speed ratio between the first drive shaft and the second drive shaft is A, the value of which is more than or equal to ⅔ and less than or equal to 3.

7. The food processor according to claim 1 , wherein the first drive shaft and the second drive shaft rotate in the same direction or in opposite directions.

8. The food processor according to claim 1 , wherein
the first transmission member and the second transmission member are bevel gears that are meshed with each other; or
the first transmission member is a turbine, and the second transmission member is a worm; or
the first transmission member and the second transmission member are two helical gears whose shafts are arranged in a staggered manner.

9. The food processor according to claim 1 , wherein the transmission assembly further comprises:
a housing comprising an upper housing and a lower housing that are assembled, the upper housing and the lower housing defining an installation cavity, the first transmission member and the second transmission member being positioned in the installation cavity, and the first drive shaft and the second drive shaft extending out of the housing.

10. The food processor according to claim 1 , wherein the transmission assembly further comprises:
a deceleration assembly arranged between the first transmission member and the motor shaft.

11. The food processor according to claim 1 , wherein the drive body is an electrified coil, the first transmission member and the second transmission member are both magnetically conducting disc bodies that rotate under a magnetic field generated by the electrified coil.
