Title:
OUTER ROTOR-TYPE WATERPROOF STRUCTURE AND OUTER ROTOR-TYPE DEVICE HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2022/141656
Kind Code:
A1
Abstract:
An outer rotor-type waterproof structure (100), comprising a waterproof assembly (3), wherein the waterproof assembly (3) covers at least an edge of a body through hole (21) on a body (2) through which a rotating shaft (11, 12) is led out, and the waterproof assembly (3) comprises a waterproof ring (31), a waterproof gasket (32), and a rotating shaft housing (33). By means of the tight fit between the waterproof ring (31) and the waterproof gasket (32), the waterproof performance can be greatly improved, and friction between the waterproof gasket (32) and the waterproof ring (31) is changed to relatively little side wall friction that can be generated by fitted side walls thereof. By means of the improvement, on one hand, the rubber waterproof gasket (32) is not in contact with a cutter head, and on the other hand, the rubber waterproof gasket (32) also avoids contact with a fluid during the operation of the device, thereby prolonging the lifetime of the waterproof gasket (32). A rotating shaft device comprising the waterproof structure (100), such as a slicer, a stirrer, etc. has a good waterproof performance.
