[0002] The existing rotary shaver has a blade net that generally only has a shaving function, and the top surface of the blade net moves close to the skin. In the announcement number CN218857030U, a blade net with a massage structure is disclosed, and the massage structure increases the skin feel during shaving. However, in the prior art, the massage structure is usually realized by installing an additional component on the blade net, and its structure is complicated. In addition, the blade net needs to be concave downward for the massage structure to be installed. The position of the blade net corresponding to the massage structure will form a partition wall in the inner cavity of the blade net that blocks the inner and outer shaving tracks. When the moving blade assembly is installed, this partition wall is easy to be very close to the blade disc of the moving blade assembly, blocking the hair shaved from the inner side of the partition wall from being discharged to the outside. Therefore, it is usually necessary to make the moving cutting teeth of the moving blade assembly relatively high so that there is an appropriate gap between the blade disc and the partition wall.

[0003] The utility model is made based on this situation. [Contents of the utility model]

With respect to the up and down direction, the slope of the first inclined section 304 is greater than that of the second inclined section 305 . Figure 7c and Figure 7d The illustrated embodiment is advantageous in that the blade 4b has a smaller angle and at the same time the mesh strip 30 between two adjacent feed holes 4 has a smaller width and better strength.

[0039] like Figure 7b-7dIn the embodiment shown, the side wall of the feed hole 4a on the side corresponding to the blade 4b has a greater slope on one side of the blade 4b than on the other side with respect to the up and down direction, which is beneficial for making the blade 4b have a smaller angle while making the mesh strip 30 between two adjacent feed holes 4 have a smaller width and better strength.

[0040] like Figure 1 and 2 As shown, the shape of the knife net body 1 is circular, or as shown in Figure 5 As shown, the shape of the knife net body 1 is a polygonal structure, or as shown in Figure 6 As shown, the shape of the knife net body 1 is a plum blossom structure.
