[0036] In related technologies, razor heads mainly use the traditional structure of a rotating foil. When trimming hair or beard, long hair is not easily caught, which can easily cause hair pulling and affect the user experience.

[0037] Reference Figures 1 to 6 According to a first aspect embodiment of the present invention, a shaver head includes a stationary blade 100 and a moving blade 200. The stationary blade 100 includes a cylindrical body 110 and a blade holder 120. The blade holder 120 is connected to one end of the cylindrical body 110. The blade holder 120 is provided with a plurality of first blades 121 spaced apart circumferentially along the cylindrical body 110. A second blade 122 is provided between each adjacent first blade 121. A first blade groove 123 is formed between the first blades 121 and the second blades 122 at intervals. A hair inlet gap 124 is formed between the second blades 122 and the cylindrical body 110 at intervals. The moving blade 200 is housed within the cylindrical body 110. The shaver includes a connecting frame 210 and a plurality of first blades 220 spaced apart along the circumferential direction. The connecting frame 210 is rotatably connected to the blade holder 120. The first blades 220 are located on the outer periphery of the connecting frame 210. The first blades 220 are used to cut hair that enters the body 110 from the first blade groove 123 or the hair inlet gap 124. In this way, the traditional shaver head can only enter the hair through the blade groove. The hair can enter the body 110 from the hair inlet gap 124 or the first blade groove 123, which can increase the hair inlet space of the shaver head, making it easier for the shaver head to enter the hair, avoiding hair pulling, and improving the user experience.

[0038] For example, when the shaver head is working, the moving blade 200 rotates relative to the stationary blade 100. The first blade 121 and the first blade 220 cooperate to cut the hair that enters the body 110 from the first groove 123. The second blade 122 and the first blade 220 cooperate to cut the hair that enters the body 110 from the hair inlet gap 124. This eliminates the need for the traditional shaver head where hair can only enter through the groove. Instead, hair can enter the body 110 from both the first groove 123 and the hair inlet gap 124, increasing the hair inlet space of the shaver head, making it easier for hair to enter, avoiding hair pulling, and improving the user experience.

[0039] In some embodiments of this utility model, the second blade 122 is spaced apart from the end face of the barrel 110, so that hair can enter the interior of the barrel 110 through the hair entry gap 124. This increases the hair entry space of the shaver head, making it easier for the shaver head to enter hair, avoiding hair pulling, and improving the user experience.

[0040] In some embodiments of this utility model, along the axial direction of the barrel 110, the projection of the second blade 122 is located on the inner side of the barrel 110, that is, the second blade 122 is spaced apart from the inner peripheral wall of the barrel 110, so that hair can enter the interior of the barrel 110 through the hair entry gap 124, which can increase the hair entry space of the shaver head, making it easier for the shaver head to enter hair, avoiding hair pulling, and improving the user experience.

[0041] In some embodiments of this utility model, the blade holder 120 is provided with a plurality of second blade grooves 125 spaced apart along the circumference of the barrel 110. The second blade grooves 125 are located inside the first blade strip 121. The moving blade 200 includes a plurality of second blades 230 spaced apart along the circumferential direction. The second blades 230 are provided on the connecting frame 210 and located inside the first blade 220. The second blades 230 are used to cut hair that enters the barrel 110 from the second blade grooves 125, which can facilitate the hair entry of the shaving head and prevent hair pulling.

[0042] In some embodiments of this utility model, the width of the first blade 220 is D, which satisfies: 1.2mm≤D≤1.5mm. For example, the value of D can be 1.2mm, 1.25mm, 1.3mm, 1.35mm, 1.4mm, 1.45mm, or 1.5mm. By reasonably designing the width of the first blade 220, the structural strength of the first blade 220 can be enhanced, thereby improving the service life of the first blade 220.

[0043] In some embodiments of this utility model, the connecting frame 210, the first blade 220, and the second blade 230 are an integral structure, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds and thus reducing the production and manufacturing cost of the shaver head.

[0044] For example, the connecting frame 210, the first blade 220, and the second blade 230 can be integrally formed by die casting, which can reduce the number of molds, thereby reducing the production cost of the molds and thus reducing the production cost of the shaver head.

[0045] As another implementation, the connecting frame 210, the first blade 220, and the second blade 230 can also be connected by welding, wherein the welding method includes, but is not limited to, resistance welding, laser welding, or ultrasonic welding.

[0046] In some embodiments of this utility model, the barrel 110 and the blade holder 120 are an integral structure, which can reduce the number of molds, thereby reducing the production and manufacturing cost of the molds and thus reducing the production and manufacturing cost of the shaver head.

[0047] For example, the barrel 110 and the blade holder 120 can be integrally formed by die casting, which can reduce the number of molds, thereby reducing the production cost of the molds and thus reducing the production cost of the shaver head.

[0048] As another embodiment, the cylinder 110 and the knife holder 120 can also be connected by welding, wherein the welding method includes, but is not limited to, resistance welding, laser welding or ultrasonic welding.

[0049] In some embodiments of this utility model, a positioning structure is provided between the connecting frame 210 and the blade holder 120, which can position the relative position of the connecting frame 210 and the blade holder 120 to facilitate the assembly of the shaver head.

[0050] In some embodiments of this utility model, the positioning structure includes a positioning hole 211 provided in the connecting frame 210 and a positioning protrusion 126 provided in the blade holder 120. The positioning protrusion 126 is accommodated in the positioning hole 211 and abuts against the side wall of the positioning hole 211, which can position the relative position of the connecting frame 210 and the blade holder 120 to facilitate the assembly of the shaver head.

[0051] For example, the positioning protrusion 126 is located at the center of the blade holder 120, and the positioning hole 211 is located at the center of the connecting frame 210. The positioning protrusion 126 is accommodated in the positioning hole 211 and abuts against the side wall of the positioning hole 211, so that the blade holder 120 and the connecting frame 210 are coaxially arranged, and the moving blade 200 can rotate around the axis of the barrel 110, which can position the relative position of the connecting frame 210 and the blade holder 120, so as to facilitate the assembly of the shaver head.

[0052] It should be noted that the positions of the positioning protrusion 126 and the positioning hole 211 can be interchanged. That is, the positioning protrusion 126 can be located on the connecting frame 210 and the positioning hole 211 can be located on the tool holder 120. The relative positions of the connecting frame 210 and the tool holder 120 can also be positioned. No restrictions are imposed here.

[0053] As another implementation, the positioning structure can also be a structure in which the positioning groove and the positioning pin cooperate, and there is no limitation here.

[0054] In some embodiments of this utility model, the tool holder 120 is provided with an annular protrusion 127 on the side facing the moving tool 200. The annular protrusion 127 is located between the first tool groove 123 and the second tool groove 125, and the annular protrusion 127 extends along the circumference of the cylinder 110, which can improve the structural strength of the stationary tool 100, thereby improving the structural stability of the stationary tool 100.

[0055] For example, the annular protrusion 127 is a ring-shaped structure that extends around the axis of the tool holder 120. Along the radial direction of the tool holder 120, the annular protrusion 127 is located between the first tool groove 123 and the second tool groove 125, which can improve the structural strength of the stationary tool 100 and thus improve the structural stability of the stationary tool 100.

[0056] In some embodiments of this utility model, the tool holder 120 is provided with an annular groove 128 on the side away from the moving tool 200. The annular groove 128 is located between the first tool groove 123 and the second tool groove 125, and the annular groove 128 extends along the circumference of the cylinder 110, which can save the material cost of the stationary tool 100.

[0057] In some embodiments of this utility model, the first and second cutting grooves are respectively connected to an annular groove, which can increase the hair entry space of the shaving head.

[0058] For example, the first groove 123 extends through the side wall of the annular groove 128, allowing hair to enter the first groove 123 through the annular groove 128. The second groove 125 extends through the side wall of the annular groove 128 away from the first groove 123, allowing hair to enter the second groove 125 through the annular groove 128, thereby increasing the hair entry space of the shaver head.

[0059] Reference Figure 1 , Figure 2 According to the second aspect of the present invention, the shaver includes the shaver head of the first aspect of the present invention. It can abandon the traditional shaver head that can only enter the hair through the blade groove. The hair can enter the body 110 through the hair entry gap 124 or the first blade groove 123, which can increase the hair entry space of the shaver head, making it easier for the shaver head to enter the hair, avoiding hair pulling, and improving the user experience.

[0060] For example, when the shaver head is working, the moving blade 200 rotates relative to the stationary blade 100. The first blade 121 and the first blade 220 cooperate to cut the hair that enters the body 110 from the first groove 123. The second blade 122 and the first blade 220 cooperate to cut the hair that enters the body 110 from the hair inlet gap 124. This eliminates the need for the traditional shaver head where hair can only enter through the groove. Instead, hair can enter the body 110 from both the first groove 123 and the hair inlet gap 124, increasing the hair inlet space of the shaver head, making it easier for hair to enter, avoiding hair pulling, and improving the user experience.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
