Embodiment 1

[0032] combined with figure 1As shown, a rotary reciprocating shaving compound cutter head includes a motor 7 for providing shaving power, a rotary shaving unit and a reciprocating shaving unit drivingly connected with the motor 7, and the rotary shaving unit includes two symmetrical The rotary shaver blade and the first drive mechanism installed on both sides of the drive shaft of the motor 7; The motor 7 is driven and connected, and the two rotating driven gears 4 are symmetrically meshed on both sides of the active eccentric gear 3, and the rotating driven gears 4 are all driven and connected to the rotary razor blade;

[0033] The reciprocating shaving unit comprises a driving eccentric gear 3 drivingly connected with the motor 7, a reciprocating cutter head 1, and a second driving mechanism drivingly connecting the driving eccentric gear 3 and the reciprocating cutting head 1; the second driving mechanism is composed of The reciprocating pendulum 5, the reciprocating fra...

Embodiment 2

[0038] In order to realize the present invention better, on the basis of the structure and principle of embodiment 1, further combine figure 1 and figure 2 As shown, the reciprocating shaving unit also includes a motor fixing base 6 for installing and fixing the motor 7, the upper surface of the motor fixing base 6 is fixedly provided with a reciprocating pendulum strut 11 penetrating and hinged with one end of the reciprocating pendulum 5 , the motor fixing seat 6 is sleeved and clamped in the motor waterproof case 8 for accommodating the motor 7 . The purpose of setting the motor fixing seat 6 is mainly to facilitate the installation of the rotating driven gear 4 and the reciprocating pendulum 5. At the same time, setting a separate motor fixing seat 6 can combine all the structures included in the rotating shaving unit and the reciprocating shaving unit with the motor. The waterproof case 8 is separated to realize a detachable structure, which is beneficial to later maint...

Embodiment 3

[0040] In order to better realize the present invention, on the basis of embodiment 2, further in conjunction with the attached Figure 1-5 As shown, in this embodiment, any end of the reciprocating pendulum 5 is provided with a hinged hole 52 for accommodating the strut 11 of the reciprocating pendulum, and a bar-shaped hole 51 is provided in the middle; the active eccentric gear 3 includes an integrally formed wheel The tooth 31 and the eccentric column 32 , and the shaft hole 33 provided at the center of the gear tooth 31 for installing the drive shaft of the motor 7 ; the strip-shaped hole 51 is sleeved on the eccentric column 32 .

[0041] working principle:

[0042] When the active eccentric gear 3 rotates, it will drive the eccentric column 32 to rotate coaxially. Since the center of the eccentric column 32 does not coincide with the center of the active eccentric gear 3, it will make a circular shaking motion relative to the active eccentric gear 3 during the rotation....

Abstract

The invention discloses a rotation and reciprocation composite razor blade. The Rotation and reciprocation composite razor blade comprises a motor, a rotating shaving unit and a reciprocating shavingunit, wherein the motor is used for providing shaving power; the rotating shaving unit and the reciprocating shaving unit are in driving connection with the motor; the rotating shaving unit comprisestwo rotating shaving blades and a first driving mechanism, wherein the rotating shaving blades are symmetrically installed at the two sides of a driving shaft of the motor; the reciprocating shaving unit comprises a driving eccentric gear, a reciprocating tool bit and a second driving mechanism, wherein the driving eccentric gear is in driving connection with the motor; and the second driving mechanism is in driving connection with the driving eccentric gear and the reciprocating tool bit. According to the rotation and reciprocation composite razor blade disclosed by the invention, the rotating shaving unit and the reciprocating shaving unit are integrated and driven by the same motor so that the limitation of an existing razor blade having a simplex shaving function is solved when the razor blade is applied to whiskers different in length, a corresponding shaving unit can be selected according to different length of the whiskers, so the rotation and reciprocation composite razor bladeis convenient and practical.

Description

technical field [0001] The invention relates to the field of razors, in particular to electric razors, in particular to a compound rotary and reciprocating shaver head. Background technique [0002] A razor is a shaving tool that almost every adult man needs to use every day. According to the principle of shaving, it can be divided into manual razors and electric razors. The structure of the manual shaver is very simple. It is mainly composed of a cutter head and a handle. The effect is also very good. At present, mainstream electric shavers on the market are roughly divided into two categories: one is a rotary cutter head, and the other is a reciprocating cutter head; people buy according to their preferences. Generally, the reciprocating cutter head is used for relatively long beards, and the rotating cutter head is used for relatively short beards. However, due to the separation of functions, users who need both can buy two types and are not easy to carry. In view of t...
