Technical Field

The present application belongs to the technical field of personal care equipment, and more particularly relates to a shaving head assembly and an electric shaving apparatus.

Background

The electric shaver consists of a mesh enclosure, a shaver blade, a micro motor and a shell. The net cover is a fixed outer blade, and a plurality of holes are formed in the net cover, and beards can extend into the holes. The micro motor is driven by electric energy to drive the shaver blade to act, and the beard extending into the hole is cut off by utilizing the shearing principle.

Since the razor blade needs to be frequently in contact with and rubbed against the beard or the net, the razor blade loses its sharpness when leaving the factory after being used for a certain period of time. As the use time increases, the razor blades become duller and the user experience is worse. However, other parts of the electric shaver are often longer in service life due to less wear. Therefore, after long-time use, the electric shaver often has the situation that the shaving is not light and clean, but other parts can still be normally used. If a new electric shaver is selected again, the use cost of the user is increased, and the waste of resources is easily caused. If the razor blades are replaced, it is difficult to obtain razor blades matching the model. In addition, the razor blade is usually integrally formed, and is influenced by processing conditions, so that the razor blade has a simple structure and a single style, and is difficult to meet diversified consumer demands.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1 and 2, the razor head assembly of the present embodiment includes a razor head 1 and razor blades 2, the razor blades 2 are detachably mounted on the razor head 1, at least a first blade mounting location and a second blade mounting location are provided on an end surface of the razor head 1, and when the razor blades 2 are mounted on the first blade mounting location or the second blade mounting location, the cutting edges 22 of the razor blades 2 are arranged in different positions along the inside and outside directions of the geometry of the razor head 1.

Wherein the cutting edges 22 of the razor blades 2 are arranged in different positions in the inner and outer direction of the geometry of the shaver head 1, meaning: the cutting edges 22 of the razor blades 2 are arranged in a direction from the geometric center of the razor cartridge 1 to the outer edge of the razor cartridge 1 (i.e., the direction S in fig. 1, the inner-outer direction S merely indicating an example of the inner-outer direction along the geometric shape of the razor cartridge 1 and not being the only limitation of the inner-outer direction), and the cutting edges 22 of the razor blades 2 are alternately spaced. For example, the shaver head 1 is a circular head, and when the shaver blades 2 are mounted at the first blade mounting position or the second blade mounting position, the inner and outer directions S are radial directions of the disk.
