Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Referring to fig. 1 to 6, the present invention discloses a head cover assembly of an electric shaver, which comprises a head cover 10 and a cutter head assembly, wherein the cutter head assembly comprises a plurality of floating frames 20, a cutter head 30 and a cutter head fixing frame 40, the floating frames 20 are mounted on the head cover 10, and a part of the floating frames extend out of the outer side of the head cover; the cutter head 30 is detachably mounted in the floating frame 20 in the head cover 10 through a cutter head fixing frame 40, and a blade is built in the cutter head.

Two symmetrically arranged floating frame fasteners 21 are arranged on the inner circumferential surface of the bottom of each floating frame 20, tool bit fixing frame fasteners 41 are symmetrically arranged at two ends of the tool bit fixing frame 40, and during installation, the tool bit fixing frame fasteners 41 can be detachably arranged on the floating frame fasteners 21 to fix the tool bit 30; in the utility model, the number of the floating frame 20, the number of the tool bit 30 and the number of the tool bit fixing frame 40 are 3, and three mounting holes 12 are arranged on the head cover 10 for mounting the floating frame 20; certainly, the number of the floating frame 20, the cutter head 30 and the cutter head fixing frame 40 is also not limited to 3, and the number can be set according to actual needs, which is not described herein; the number of the three mounting holes 12 provided in the head cap 10 is set according to the number of the floating frame 20, the bit 30, and the bit holder 40.

The utility model discloses all be equipped with two draw-in grooves 22 on the outer peripheral face of the bottom of every floating frame 20, all be equipped with two lugs 11 on the inner peripheral face of every mounting hole 12 on skull 10 symmetrically, during the installation, floating frame 20 realizes both positions in lug 11 screw in draw-in groove 22 through the mode of rotation, adopts the mode of screw in block to improve the convenience of installation; the number of the card slots 22 and the number of the bumps 11 are not limited to two, and they may be determined according to actual needs, and are not described herein.

Furthermore, draw-in groove 22 is the little big waist type groove in the diameter outward in this application, and the diameter of lug 11 is less than the diameter of draw-in groove 22 import (being the diameter of waist type groove import), and this design makes lug 11 get into from the import of draw-in groove 22 under the effect of external force, then firmly block in draw-in groove 22 (the great part of draw-in groove 22 diameter), and is difficult for droing.

Further, when the bump 11 is located in the slot 22, the bump and the inner wall of the slot are in interference fit, and the interference fit enables the bump and the inner wall to be tightly combined when the bump and the inner wall are vibrated, so that looseness cannot be generated, and the bump and the inner wall of the slot are further prevented from falling off.

Preferably, the floating frame fastener 21 of the present application is an elastic fastener integrally formed with the floating frame 20, and has a simple structure and a low processing cost, and the floating frame fastener 21 is made of an elastic material; the floating frame fastener 21 is a step-shaped structure with a groove 21a at the upper part and a boss 21b at the lower part; the cutter head fixing frame fastener 41 is an elastic fastener integrally formed with the cutter head fixing frame 40, the structure is simple, the processing cost is low, and the cutter head fixing frame fastener 41 is made of an elastic material; a bayonet 41a is arranged on the peripheral surface of the cutter head fixing frame fastener 41; when the tool bit fixing fastener 41 is installed, the tool bit fixing fastener 41 is pressed to be compressed, the bayonet 41a is aligned to the boss 21b, the tool bit fixing fastener 41 is loosened, the boss 21b is clamped into the bayonet 41a due to the elastic restoring force of the tool bit fixing fastener 41, the floating frame fastener 21 is connected with the tool bit fixing fastener 41, and the tool bit 30 is fixed finally.

Further, because the floating frame fastener 21 and the bit mount fastener 41 are both elastic members, they are certainly extruded with each other, and because the thickness of the boss 21b is smaller than the depth of the bayonet 41a, a space is reserved for extrusion, so that the contact surfaces of the floating frame fastener 21 and the bit mount fastener 41 are firmly attached together, and the sealing property and the stability are improved.

Further, the linear distance between the bottoms of the two symmetrical bayonets 41a is smaller than the linear distance between the two symmetrical bosses 21b, and by the design, when the tool bit fixing frame 40 is installed, the tool bit fixing frame fastener 41 must be compressed first, and after the bosses 21b are placed in the bayonets 41a, the tool bit fixing frame fastener 41 and the floating frame fastener 21 are squeezed with each other due to the elastic restoring force of the tool bit fixing frame fastener 41 and the floating frame fastener 21, so that the bosses 21b are tightly clamped in the bayonets 41 a.

Furthermore, the cutter head fixing frame fastener 41 is arc-shaped, and the arc-shaped structure enables the cutter head fixing frame fastener 41 to have stronger elastic restoring force, so that the stability after installation is further improved; of course, the tool bit fixing frame fastener can also be in other shapes, and the description is omitted here.

Further, the included angle between the floating frame fastener 21 and the horizontal plane is 65-85 °, preferably 75 °, and since the floating frame fastener 21 itself has an inclination, after it is pressed, the elastic restoring force is stronger, and the boss 21b can be firmly fixed in the bayonet 41a by matching with the elastic restoring force of the bit fixing frame fastener 41.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
