Detailed Implementation

[0023] The technical features of this utility model will be further described in detail below with reference to the accompanying drawings so that those skilled in the art can understand them.

[0024] A reciprocating double-blade razor head, such as Figures 1-5As shown, the device includes a base shell 1 and a ring cover 2 fixedly connected to the base shell 1. A mounting component 3 for connecting the main unit to reciprocate is movably disposed within the base shell 1. A moving blade 4 that moves synchronously with the mounting component 3 is fixedly mounted on the mounting component 3. A stationary blade 5 that engages with the teeth of the moving blade 4 is disposed on the outer side of the ring cover 2. A fixing component 6 is disposed on the mounting component 3 and above the moving blade 4. A moving blade mesh 7 is fixedly mounted on the fixing component 6. A stationary blade mesh 8 that engages with the moving blade mesh 7 is disposed on the inner side of the ring cover 2. The two sets of shaving blades, the moving blade 4 and the stationary blade 5, and the moving blade mesh 7 and the stationary blade mesh 8, can significantly increase the size of the shaving area and the contact area between the shaving component and the skin, thereby effectively enhancing the shaving effect and efficiency of the reciprocating shaving head.

[0025] Specifically, a first spring 9 is provided between the mounting member 3 and the bottom shell 1 to hold the mounting member 3 so that the moving blade 4 teeth fit into the stationary blade 5 teeth. A second spring 10 is provided between the fixing member 6 and the mounting member 3 to hold the fixing member 6 so that the moving blade net 7 fits into the stationary blade net 8. There are two of each of the first spring 9 and the second spring 10, which are symmetrically arranged. The first spring 9 and the second spring 10 can make the blade and the blade net fit into each other to enhance the cutting effect of the blade and the blade net, while preventing hair from getting caught.

[0026] Furthermore, the teeth of the moving blade 4 and the stationary blade 5 extend to the outer edges on both sides, and the teeth of the stationary blade 5 extend outward beyond the teeth of the moving blade 4. An arc-shaped protective head 11 is provided at the end of the teeth of the stationary blade 5. The protective head 11 can prevent skin scratches and enhance comfort. Both the moving blade net 7 and the stationary blade net 8 are upwardly curved arcs, which makes it easier for the stationary blade net 8 to fit the skin during shaving. At the same time, it makes it easier for hair to enter the cutting hole of the stationary blade net 8, thereby enhancing the shaving effect and efficiency.

[0027] In addition, a strip-shaped opening 29 is provided on the bottom surface of the bottom shell 1, and two reciprocating baffles 30 extending downward through the opening 29 are symmetrically provided at the center of the bottom end of the mounting member 3. The length of the opening 29 needs to be greater than the reciprocating stroke of the reciprocating baffles 30 so that the mounting member 3 can move freely in the bottom shell 1.

[0028] Specifically, mounting blocks 12 are symmetrically provided at both ends of the mounting component 3, and mounting holes 13 for nesting and locking the mounting blocks 12 are provided at both ends of the moving blade 4. The moving blade 4 is tightly fitted and nested with the mounting blocks 12 on the mounting component 3 through the mounting holes 13.

[0029] In addition, a step 14 is provided at the bottom of the outer edge of the ring cover 2, and the stationary blade 5 is nested on the step 14. The stationary blade 5 is clamped and fixed to the outer edge of the ring cover 2 by the bottom shell 1.

[0030] Specifically, symmetrically arranged upward-extending buckles 15 are provided on both sides of the upper center of the mounting component 3, and correspondingly arranged clip heads 16 for engaging the buckles 15 are provided on the inner wall of the fixing component 6. The fixing component 6 can be attached to the upper part of the mounting component 3 in a floating manner, so that the moving blade net 7 can float up and down by the second spring 10, which can enhance the shaving effect and facilitate the cleaning of hair stuck in the gap of the blade head.

[0031] In addition, a number of first positioning notches 17 and first slots 18 are symmetrically provided on the side walls on both sides of the moving blade mesh 7. On the outer walls on both sides of the fixing member 6, there are corresponding first positioning protrusions 19 for engaging the first positioning notches 17 and first locking blocks 20 for engaging the first slots 18. The moving blade mesh 7 and the fixing member 6 are fastened together and fixed, which is convenient for assembly.

[0032] Specifically, a number of second positioning notches 21 and second latches 22 are symmetrically provided on the outer edges of both sides of the stationary knife mesh 8. On both sides of the bottom end of the ring cover 2, there are corresponding second positioning protrusions 23 for engaging the second positioning notches 21 and second latches 24 for engaging the second latches 22. The stationary knife mesh 8 is pushed upward from the bottom end of the ring cover 2 so that the two are locked together and assembled quickly and easily.

[0033] In addition, positioning holes 25 and fixing holes 26 are symmetrically provided on the bottom surface at both ends of the ring cover 2. Positioning pins 27 for inserting into the positioning holes 25 and through holes 28 for passing through screws are provided at both ends of the bottom shell 1. After the screw passes through the through hole 28, it is screwed into the fixing hole 26, so that the ring cover 2 and the bottom shell 1 can be fixedly connected.
