Example one
Referring to fig. 1, an embodiment of the present application provides an inner cutter fixing structure, including: an outer blade shell 11, one end of which is opened and a first accommodating cavity 111 is formed inside; the fixing ring 12 is covered at the opening end of the outer cutter shell 11; the outer cutter 13 is arranged in the first accommodating cavity 111 and is arranged close to an opening at one end of the fixing ring 12, and a second accommodating cavity is formed in the outer cutter 13; and the inner knife 14 is arranged in the second accommodating cavity.
As shown in fig. 1, the fixing ring 12 includes an inner ring 121 and an outer ring 122, at least two connecting arms 121a are uniformly connected between an outer circumferential wall of the inner ring 121 and an inner circumferential wall of the outer ring 122, and two end surfaces of the inner ring 121 and the outer ring 122 are respectively located on the same plane, so as to save space; the outer peripheral wall of the outer ring 122 is recessed inwardly to form two oppositely disposed first notches 122a, and the outer peripheral wall of the outer ring 122 is protruded away from the first notches 122a to form two oppositely disposed clamping portions 122b.
In this embodiment, four connecting arms 121a are uniformly connected between the outer circumferential wall of the inner ring 121 and the inner circumferential wall of the outer ring 122 to increase the connection strength between the inner ring 121 and the outer ring 122, the connecting arms 121a can also prevent the inner knife 14 from falling out of the second accommodating cavity, and the connecting arms 121a are uniformly distributed to balance the stress of the inner knife and further prevent the inner ring 121 and the outer ring 122 from being separated.
In this embodiment, two opposite clamping portions 122b are further formed by protruding the outer peripheral wall of the outer ring 122 away from the first notch 122a, and clamping slots 115 matched with the clamping portions 122b are respectively formed on two opposite sides of the inner wall of the outer cutter housing 11 near the opening 113; the outer circumferential wall of the outer ring 122 is located at each connecting arm 121a and is recessed inwards to form two first notches 122a which are arranged oppositely, inner wall portions of two opposite sides of the outer cutter casing 11 extend inwards to form protrusions 112 matched with the first notches 122a, the clamping portion 122b and the clamping groove 115 are arranged to enable the fixing ring 12 and the outer cutter casing 11 to be fixedly connected, and the first notches 122a and the protrusions 112 are arranged to prevent the fixing ring 12 from rotating to be separated from the outer cutter casing 11.
Specifically, in order to avoid the outer cutter 13 from rotating in the outer cutter housing 11, the outer end wall 131 of the open end of the outer cutter 13 extends radially outward, and the outer end walls 131 on the two opposite sides are respectively provided with the second notches 132 matched with the protrusions 112, so that the outer cutter 13 is prevented from rotating in the outer cutter housing 11, and the outer cutter can float up and down to fit the face of the user during shaving, thereby improving user experience.
Specifically, the inner wall of the outer blade shell 11 is inwardly reduced in diameter to form a limiting step 116 matched with the outer end wall 131, and the limiting step 116 and the clamping groove 115 are provided with a spacing distance so that the inner blade 14 and the outer blade 13 can vertically float in the outer blade shell 11 to be attached to the face of a user, and user experience is improved.
As shown in fig. 1, the outer edge of the inner blade 14 protrudes toward the side of the fixing ring 12 to form a protruding ring 141, and the diameter of the protruding ring 141 is larger than the outer diameter of the inner ring 121 and smaller than the inner diameter of the outer ring 122, so that the connecting arm 121a can prevent the inner blade 14 from falling out of the second accommodating cavity.
Specifically, the center of the outer cutter 14 protrudes toward one side of the fixing ring 12 to form a rotating shaft 142, the outer diameter of the rotating shaft 142 is smaller than the inner diameter of the inner ring 121, and the inner ring 121 can enable the rotating shaft 142 to protrude from the center of the ring, so that the inner cutter 14 can float up and down in the second accommodating cavity.
As shown in fig. 1, in order to make the inner knife 14 rotate in the outer knife 13 for normal operation, a first fixed shaft 143 is formed by protruding the center of the inner knife 14 away from the side of the fixed ring 12, and a fixed hole 143a is opened at the center of the first fixed shaft 143; the center of the inner end wall of the outer cutter 13 protrudes toward the inner cutter 14 to form a second fixing shaft 133 matched with the fixing hole 143a, the second fixing shaft 133 is inserted into the fixing hole 143a so that the inner cutter 14 rotates around the second fixing shaft 133, and the second fixing shaft 133 can axially slide in the fixing hole 143a while the inner cutter 14 rotates around the second fixing shaft 133 in the outer cutter 13 to perform a shaving process, so that the inner cutter 14 can axially float up and down in the outer cutter 13 to fit the face of a user, and user experience is improved.
In order to facilitate the detachment, the outer ring 122 is provided with a detachment opening 122c at each of the clamping portions 122b, and the fixing ring 12 can be detached from the outer cutter shell 11 by inserting a tool into the detachment opening 122 c.
Example two
Fig. 2 is a cross-sectional view of the outer blade fixing structure 1 when the inner blade 14 is fixed in the second accommodating cavity, the outer blade 13 is fixed in the first accommodating cavity 111, and the fixing ring 12 is covered on the opening end of the outer blade shell 11; fig. 3 is a top view of the outer cutter fixing structure 1 in fig. 2.
When the fixing ring 12 covers the opening end of the outer blade shell 11, each protrusion 112 abuts against the first notch 122a, and each clamping portion 122b is correspondingly clamped in the clamping groove 115. The arrangement of the clamping portion 122b and the clamping groove 115 can fixedly connect the fixing ring 12 and the outer cutter casing 11, and the arrangement of the first notch 122a and the protrusion 112 can prevent the fixing ring 12 from rotating to get out of the outer cutter casing 11, and at the same time, the clamping portion 122b can be conveniently inserted into the clamping groove 115 by inserting the first notch 122a and the protrusion 112. Each first recess 122a and each connecting arm 121a are correspondingly positioned to facilitate alignment of the first recess 122a and the protrusion 112 to connect the fixing ring 12 and the outer blade shell 11.
When the outer cutter 13 is installed inside the first accommodating cavity 111 of the outer cutter housing 11, each protrusion 112 abuts against the second notch 132, so that the outer cutter 13 is prevented from rotating in the outer cutter housing 11, and the outer cutter can float up and down to fit the face of a user during shaving, thereby improving user experience.
With reference to fig. 2 and 3, the inner wall of the outer blade housing 11 is inwardly reduced to form a limiting step 116 adapted to the outer end wall 131, a distance is provided between the limiting step 116 and the locking groove 115 so that the outer end wall 131 can move between the distances, and the arrangement enables the inner blade 14 and the outer blade 13 to float up and down in the outer blade housing 11 to fit the face of a user, thereby improving user experience.
When the inner cutter 14 is fixed in the second receiving chamber, since the outer diameter of the rotating shaft 142 is smaller than the inner diameter of the inner ring 121, the inner ring 121 may cause the rotating shaft 142 to protrude from the center of the ring, so that the inner cutter 14 may float up and down in the second receiving chamber.
EXAMPLE III
