Description

Technical Field

[0001] This invention relates to shaving equipment, and more particularly to shaving foil, shaving head, and shaving blade. Background Technology

[0002] The razor head is a key component used for shaving in daily life. Currently, there are roughly three types of razor heads: The first is the reciprocating electric razor head, which uses a mesh structure for hair entry. This structure prevents long hairs from entering the cutting aperture, meaning most mesh razor heads cannot cut relatively soft long hairs. The second type is the reciprocating clipper head structure for cutting long hair. This clipper head structure uses toothed moving blades and toothed fixed blades to cut long hair. In this cutting method, the blades directly contact the skin, which can easily cause cuts. Furthermore, the blade thickness makes it impossible to cut short hairs. The third type is a mesh-type razor head with clipper heads stacked on the side, allowing the razor to handle both short and long hair. This type of razor head is inconvenient to switch between, and its structure is complex, bulky, and inefficient. How to provide a razor head with a simple structure that can adapt to both short and long hair is a research object for those skilled in the art. Summary of the Invention

[0033] The following is in conjunction with the appendix Figure 1-13 The invention will be further described in detail with reference to the embodiments. Example 1

[0034] The shaving foil includes a foil housing 10, which includes a head 101. The head 101 has a cavity. The included angle between the front and rear sides of the head 101 is α, where 0° < α < 120°. In this embodiment, α is 60°, meaning the cross-sectional shape of the head 101 is an inverted "V". The junction of the two sides of the head 101 is rounded. The top of the head 101 has a number of comb holes 1011 for combing body hair. The comb holes 1011 are notched comb holes. All the comb holes 1011 are arranged in a row and extend through both sides of the head 101, so that both sides of the shaving foil can be used to comb body hair. All comb holes 1011 are connected to the receiving cavity. The comb holes 1011 are used to comb body hair and introduce body hair into the receiving cavity. The body hair first enters the comb hole 1011 through the notch of the comb hole 1011, so that the body hair is cut by the blade 13 in the receiving cavity.

[0035] The top of the shell head 101 is provided with a number of comb teeth 1012. The cross-sectional shape of the comb teeth 1012 is an inverted "V" shape. Half of each comb tooth 1012 is on the front side of the shell head 101, and the other half of each comb tooth 1012 is on the rear side of the shell head 101. A comb hole 1011 is formed between adjacent comb teeth 1012. When the front side of the shell head 101 is projected, the end face shape of the comb teeth 1012 is rectangular. In other embodiments, it can also be square, such as... Figure 2As shown. Since the projected shape of the end face of the comb teeth 1012 is rectangular, the projected shape of the comb hole 1011 is also rectangular. The comb hole 1011 penetrates the top of the shell head 101, making it convenient for body hair to enter the comb hole 1011.

[0036] The blade shell 10 includes a shell body 102, with a shell head 101 integrally formed on the shell body 102. The two sides of the shell body 102 are parallel to each other, and the shell body 102 is square.
