Description

Technical Field

[0001] This utility model relates to the field of shaver technology, specifically to a high-efficiency three-ring shaver head with an inner floating ring. Background Technology

[0002] As an important tool for men's daily personal care, the core performance indicators of shavers are the cleanliness, comfort, and efficiency of shaving. Most mainstream high-end shavers on the market adopt the "three-ring" head design, which covers the shaving area through three large ring-shaped foils (fixed blades). The moving blades and fixed blades inside this type of head usually adopt an integrated structure, that is, each foil and the moving blade assembly below it are a whole unit.

[0003] Although this one-piece large three-ring shaving head provides a larger shaving contact area, its inherent structural defects have gradually become apparent during actual use, mainly in terms of shaving fit. Due to the large area of ​​the foil, the contact area between the moving and stationary blades is also correspondingly increased, which makes the entire shaving head unit more rigid and less flexible.

[0004] When there are variations in facial contours, such as the jawline, neck, and philtrum, the large, one-piece shaving head cannot adapt to these changes and cannot maintain a close fit to the skin. As a result, short stubble in these contour transition areas is difficult for the foil to capture and remove effectively. Users must repeatedly adjust the shaving angle or shave the same area multiple times, which significantly reduces shaving efficiency. Furthermore, repeatedly shaving the same area can cause discomfort such as burning and pulling on the skin, severely impacting the shaving experience. Utility Model Content
