Preferably, the oil-proof sealing ring is further provided with a tangential edge, the tangential edge is used for being tightly attached to the plastic package casing, the tangential edge of the oil-proof sealing ring is tightly attached to the plastic package casing, and the oil-proof sealing ring is tightly attached to the rear end cover through the connecting edge and the two adjacent edges of the connecting edge, so that a complete and fixed sealing structure is formed.

Preferably, the rubber oil-proof cap is provided with a top, a bottom and a hollow part, the width of the rubber oil-proof cap is gradually increased from the top to the bottom, the cross section of the rubber oil-proof cap can be circular, the longitudinal section of the rubber oil-proof cap can be trapezoidal, the structure which keeps the upper narrow and the lower wide can increase the stability of the rubber oil-proof cap, the rubber oil-proof cap can not be driven to move towards the direction of being far away from the plastic package shell when the rotating shaft rotates, and therefore the better sealing effect is achieved.

Preferably, the hollow part of the rubber oil-proof cap is tightly attached to the rotating shaft, and the bottom of the rubber oil-proof cap is tightly attached to the plastic package shell, so that a stable sealing structure is formed, and oil smoke can be effectively prevented from entering the motor from a gap.

The utility model has the advantages that:

1. the utility model discloses a polygon grease proofing sealing washer can laminate the gap that plastic envelope casing and rear end cap produced more to reach better sealed effect.

2. The utility model discloses add rubber oil-proof cap in the junction of plastic envelope casing and pivot, can prevent effectively that the oil smoke from getting into the motor from here gap to the grease proofing protection to the motor is realized.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example (b):

the oil-proof plastic package casing sealing structure for the integrated kitchen range comprises an oil-proof plastic package motor body, wherein a motor is arranged in the body, a plastic package casing 1 is arranged outside the motor, a rotating shaft 3 is arranged perpendicular to the plastic package casing 1 and penetrates through the plastic package casing 1 to be connected with the motor, and a gap exists at the joint of the rotating shaft 3 and the plastic package casing 1, so that oil smoke is easily caused to enter the gap from the gap and the service life of the internal motor is damaged; the bottom of the plastic package machine shell 1 is connected with the iron rear end cover 2, and the joint of the iron rear end cover 2 and the plastic package machine shell 1 is provided with two vertical edges, so that the rear end cover 2 and the plastic package machine shell 1 cannot be completely attached, and a gap is formed at the joint of the two, and oil smoke is easy to enter.
