[0037] Reference Figures 1 to 3 , the present utility model provides an antibacterial electric shaver, which includes a knife grid 1, a net cover 2, a blade 4, and a connecting piece 5 embedded in the blade 4. The net cover 2 is installed on the knife grid 1, and the connecting piece 5 equipped with the blade 4 is arranged inside the net cover 2. The knife grid 1 and the connecting piece 5 are made of antibacterial plastic; antibacterial coatings are provided on the surfaces of the net cover 2 and the blade 4.

[0038] In this embodiment, the electric shaver does not have a dedicated sterilization part, which simplifies the structure of the shaver, has a simple assembly, and reduces the material and labor costs; the knife grid 1 and the connecting piece 5 are made of antibacterial plastic, and the method is simpler and the cost is lower; the antibacterial coatings on the surfaces of the blade 4 and the net cover 2 enable all the components in contact with the skin of the shaver to have antibacterial effects, reduce the growth of bacteria inside the net cover 2, and significantly reduce the risk of bacterial infection.

[0039] Specifically, the cutter grid frame 1 is provided with an installation groove penetrating through the middle, and the mesh cover 2 is installed in the installation groove; the cutter blade 4 is fixedly installed on the connecting piece 5, the inner surface of the mesh cover 2 is provided with a first fixing piece, and one end of the connecting piece 5 close to the inner surface of the mesh cover 2 is correspondingly provided with a second fixing piece, and the second fixing piece is connected to the first fixing piece; the end of the connecting piece 5 away from the inner surface of the mesh cover 2 is further provided with a third fixing piece connected to the whole machine. The second fixing piece and the first fixing piece are mutually matched, and the first fixing piece, the second fixing piece, and the third fixing piece include but are not limited to installation structures such as shafts and holes. The surfaces of the mesh cover 2 and the cutter blade 4 are treated with a coating and are attached with an antibacterial coating. The cutter grid frame 1 and the connecting piece 5 are antibacterial plastics. The antibacterial plastic is mainly obtained by adding an antibacterial agent to ordinary plastic. In this embodiment, before the cutter grid frame 1 and the connecting piece 5 are injection-molded, antibacterial masterbatch is added to the plastic particles, and after being stirred evenly, they are injection-molded. The inside and surface of the cutter grid frame 1 and the connecting piece 5 both contain antibacterial masterbatch; the addition amount of the antibacterial masterbatch is 1%-10% of the weight of the plastic particles of the cutter grid frame 1 or the connecting piece 5. It should be noted that the cutter grid frame 1, the mesh cover 2, the cutter blade 4, and the connecting piece 5 can be composed of one or more parts.

[0040] Further, referring to Figure 4 , silver ion antibacterial particles 101 are provided on the surface and inside of the cutter grid frame 1 or the connecting piece 5. After the silver ion antibacterial particles 101 are put into the plastic particles of the cutter grid frame 1 or the connecting piece 5, they should be stirred evenly so that the silver ion antibacterial particles 101 are evenly distributed in the cutter grid frame 1 or the connecting piece 5. The weight ratio of the silver ion antibacterial particles 101 should also be strictly controlled. The addition amount of the silver ion antibacterial particles 101 is 3%-5% of the weight of the plastic particles of the cutter grid frame 1 or the connecting piece 5. If the addition amount of the silver ion antibacterial particles 101 is too small, the sterilization effect is not ideal. If the addition amount of the silver ion antibacterial particles 101 is too large, the plastic properties will be affected. Specifically, the antibacterial masterbatch is any one of silver ion antibacterial particles 101, copper ion antibacterial particles, zinc ion antibacterial particles, cerium ion antibacterial particles, gallium ion antibacterial particles, and magnesium ion antibacterial particles. It should be noted that in the field of antibacterial plastics, based on silver ion technology, before plastic molding, silver ion antibacterial powder and silver ion antibacterial liquid can also be added to make the molded plastic have antibacterial effects.

[0041] Further, both the cutter blade 4 and the mesh cover 2 are made of metal; the antibacterial coating includes an inorganic antibacterial coating. Specifically, the antibacterial coating is any one of zinc ion antibacterial coating 401, copper ion antibacterial coating 201, silver ion antibacterial coating, cerium ion antibacterial coating, gallium ion antibacterial coating, and magnesium ion antibacterial coating. The preparation methods of the inorganic antibacterial coating include existing methods such as ultrasonic spraying, electroplating, or chemical methods. Referring to Figure 5, the blade 4 is subjected to an antibacterial coating treatment in the last process (for example, after the rust prevention treatment on the surface of the blade 4, antibacterial coatings are applied to the four surfaces around the cutting edge surface of the blade 4), and a zinc ion antibacterial coating 401 is formed on the surface of the blade 4, and its area covers more than 80% of the surface area of the blade 4. Adding the zinc ion antibacterial coating 401 to the blade 4 can effectively inhibit the growth of bacteria on the surface of the blade 4 and further reduce the risk of bacterial infection. Refer to Figure 6 , after appropriate processes (no longer removing materials from the outer surface and no longer adding other materials to the outer surface), the mesh cover 2 is subjected to an antibacterial coating treatment, and a copper ion antibacterial coating 201 is formed on the surface of the mesh cover 2, and its area covers at least the outer surface of the mesh cover 2 in contact with the skin.

[0042] It should be noted that the antibacterial coating may also include an organic antibacterial coating, such as chitin, chitosan and their derivatives, etc., which are all existing means in the field of antibacterial.

[0043] Furthermore, it further includes a decorative piece 3. A groove is provided on the outer surface of the mesh cover 2, and the decorative piece 3 is installed in the groove, and an antibacterial coating is provided on the surface of the decorative piece 3.

[0044] Specifically, the decorative piece 3 is made of metal. After appropriate processes (no longer removing materials from the outer surface and no longer adding other materials to the outer surface), the decorative piece 3 is subjected to an antibacterial coating treatment, and a copper ion antibacterial coating 201 is formed on the surface of the decorative piece 3, and its area covers at least the outer surface of the decorative piece 3 in contact with the skin.

[0045] It should be noted that the above embodiments can be freely combined according to needs. The above is only the preferred embodiment of the present invention.
