[0025] In order to solve the above technical problems, the present invention provides an outer blade assembly of an electric shaver, which is used for a reciprocating shaver, comprising:

[0026] An outer knife, wherein the outer knife is provided with cutting teeth and / or cutting holes along its length direction,

[0027] An external tool holder, the external tool holder is used to install an external tool,

[0028] The skin contact surface is used to stick to the skin when shaving.

[0032] In the outer blade assembly of an electric shaver as described above, the height h of the ball protruding from the skin contact surface and the ball diameter r of the ball satisfy 0.05mm≤h≤0.7r≤1mm.

[0033] Compared with the prior art, the present invention has the following advantages:

[0034] 1. The electric shaver blade net of the rotary shaver of the present invention has a plurality of rolling balls protruding from the skin contact surface on the top of the net. When shaving, the top of the net is pressed on the skin, the skin contact surface moves against the skin, the balls protrude from the skin contact surface, and the protruding parts thereof are also pressed on the skin. The balls move on the skin and roll due to friction on the skin, which can improve the skin feel, weaken the stimulation caused by shaving, and improve the comfort of shaving.

[0035] 2. The present invention is used for the blade net of the electric shaver of the rotary shaver, and a ball is arranged on the blade net. The ball is a sphere and can roll in any direction of 360 degrees. Even if the rotary shaver is held by hand and moved on the skin in different directions without rotating the angle of the rotary shaver, the ball can roll in the corresponding direction, avoiding being restricted by the moving direction of the rotary shaver, and can better match the non-directional movement of the rotary shaver.

[0036] 3. The blade net of the electric shaver used for the rotary shaver of the present invention has a height h of the ball protruding from the skin contact surface that is smaller than the ball diameter r, particularly h≤0.7r, and 0.05mm≤h≤0.5mm. This can prevent the ball from protruding too high, which may affect the stability of the ball assembly, and prevent the skin from being lifted too high, which may cause the skin contact surface in the shaving area to have poor contact with the skin, thereby reducing the shaving efficiency and the degree of cleanliness. In addition, a ball that protrudes too high may also affect the skin feel. In addition, it can prevent the ball from protruding too small, which may cause friction with the skin and make it difficult for the ball to roll.

[0037] 4. The present invention is used for the blade net of an electric shaver of a rotary shaver, and a plurality of balls are arranged in a circumferential direction on the inner side and / or the outer side of a shaving track. Since skin stimulation during shaving is mainly caused by the interaction between the rotating motion of the moving blade and the edge of the entrance pore, the skin stimulation area is distributed on the annular shaving track, and a plurality of balls are evenly or nearly evenly distributed in a circumferential direction on the inner side and / or the outer side of the shaving track. The effective area of ​​the balls on the blade net is evenly distributed, which is beneficial to improving the skin feel, and the balls are closer to where the skin stimulation is generated, so as to better reduce the stimulation caused by shaving.

[0038] 5. The blade net of the electric shaver used for the rotary shaver of the present invention has inner and outer continuous skin contact surfaces between two adjacent shaving tracks on the inner and outer sides of the ball. The skin contact surfaces corresponding to the two shaving tracks are continuous. In addition, the ball protrudes on the middle of the skin contact surfaces of the two shaving tracks, which can better improve the skin feel and comfort.

[0039] 6. The blade net of the electric shaver used for the rotary shaver of the present invention is manufactured by powder metallurgy, and the exposed opening and the ball groove are formed by injection molding of a mold, and the production process is simple.

[0040] 7. The blade net of the electric shaver used for the rotary shaver of the present invention is made of powder metallurgy, and the top of the net includes an extension extending to the outside of the blade net body, and the blade net body is provided with a floating connection structure, and a plurality of balls are protruded on the skin contact surface of the extension part, so as to improve the skin feel and comfort of shaving. The extension part cooperates with the floating connection structure and can be directly installed on the blade head frame for use, avoiding the need to use another blade frame to float the blade net on the blade head frame in the prior art, thereby saving parts.

[0041] 8. The outer blade assembly of the electric shaver used for the rotary shaver of the present invention is provided with a plurality of rolling balls protruding from the corresponding skin contact surface on the mesh top and / or the blade holder. The protruding balls improve the skin feel during shaving, weaken the stimulation caused by shaving, and improve the comfort of shaving.

[0042] 9. The outer blade assembly of the electric shaver of the reciprocating shaver of the present invention has several rows of balls, each row includes a plurality of balls protruding from the skin contact surface and capable of rolling. The protruding balls improve the skin feel of the reciprocating shaver during shaving, weaken the stimulation caused by shaving, and improve the comfort of shaving.

[0060] The present invention will be further described below in conjunction with the accompanying drawings:

[0061] like Figures 1 to 12 The blade net 100 of an electric shaver shown is used for a rotary shaver and comprises a blade net body 1, wherein the blade net body 1 is provided with a net top 10, wherein the net top 10 has a skin contact surface 11 for being attached to the skin during operation, and wherein a plurality of rolling balls 2 protruding from the skin contact surface 11 are provided on the net top 10. During shaving, the net top 10 is pressed against the skin, the skin contact surface 11 moves against the skin, the balls 2 protrude from the skin contact surface 11, and the protruding parts thereof are also pressed against the skin, and the smooth surface of the balls 2 moves on the skin and rolls due to friction on the skin, which can improve the skin feel, weaken the stimulation caused by shaving, and improve the comfort of shaving.

[0062] A ball bearing is arranged on the blade net of the rotary shaver. The ball bearing is a sphere and can roll in any direction of 360 degrees. Even if the rotary shaver is held in the hand and moved in different directions on the skin without rotating the angle of the rotary shaver, the ball bearing can roll in the corresponding direction, thereby avoiding being restricted by the moving direction of the rotary shaver and being able to better match the non-directional movement use of the rotary shaver.
