Abstract

The present invention relates to a kind of inner cutting head of rotary shaver with simple machining, high strength and low cost. The inner cutting head includes inner support ring with several inner support pins in the circumferencial direction, outer support ring with corresponding outer support pins in the circumferencial direction, and inner cutting bits, each of which is set between the end of one inner support pin and the end of one outer support pin and forms one cutting edge with its top and front side wall.

Description

technical field [0001] The invention relates to an inner cutter head of a rotary shaver. Background technique [0002] The rotary razor heads currently on the market generally include an inner cutter head and an outer cutter head. The outer cutter head generally remains stationary, and the inner cutter head can rotate relative to the outer cutter head, so the inner cutter head is also called a moving cutter head. The inner cutter head of the rotary shaver in the prior art mainly includes a planar annular support, a plurality of upright support posts rising from the outer peripheral edge of the planar annular support, and an inner cutter body formed on the end of the upright support posts. In the rotary shaver inner cutter head with this structure, each inner cutter body has only one upright support column, the inner cutter body has low strength, high material requirements, complex processing, high cost, and the inner cutter body formed by processing is ring-shaped The accur...
