Description

Reciprocating razor

Technical Field

The present utility model relates to shavers, and in particular to reciprocating shavers.

Background

The reciprocating shaver comprises a front shaver net, a rear shaver head and a driving device, wherein the shaver net is pressed close to the skin forwards during shaving, beard on the skin penetrates through meshes backwards and stretches into the rear side of the shaver net, and the driving device drives the shaver head to move left and right or up and down so as to cut off the beard together with the shaver net. The left-right direction and the up-down direction are both lateral, and the driving device drives the cutter head to reciprocate laterally. The driving device is usually positioned at the rear of the cutter head and comprises a driving motor, an eccentric shaft, a movable part and a guide part, wherein the driving motor is arranged at the front end of the driving shaft of the driving motor, the eccentric shaft is arranged at the front side of the eccentric shaft and driven by the eccentric shaft, the guide part is arranged at the front side of the eccentric shaft and covers the movable part backwards, an extension rod is arranged at the front part of the movable part in a stretching way, a rod penetrating hole is formed in the front part of the guide part for the extension rod to penetrate through, the cutter head is arranged at the front part of the extension rod, and the driving motor drives the movable part to laterally reciprocate under the guide of the guide part through the rotation of the driving eccentric shaft so as to drive the cutter head to laterally reciprocate. The disadvantages of such reciprocating shavers are: the head and the eccentric shaft must be kept at a relatively large distance so that a space is left between them for the movable member, the guide member and the extension rod, which results in a relatively large shaver.

Detailed Description

The utility model is further described in detail below in connection with the detailed description.

The reciprocating shaver, see fig. 1, comprises a razor module 10, a drive module 20 and a cap 30, all of which have a magnet 40 mounted therein. The razor module 10 is detachably mounted on the front side of the driving module 20 in a magnetic attraction manner, the cover 30 detachably covers the razor module 10 in a magnetic attraction manner in normal times, the razor module 10 is exposed when shaving, the front end of the exposed razor module 10 is close to the skin, and the driving module 20 drives the razor of the razor module 10 to move sideways to shave beards on the skin. The other directions except the front-rear direction are lateral directions, and in this embodiment, the lateral directions are specifically left-right directions.

The razor module 10 is shown in fig. 2 and comprises front and rear protective cases 101 and 102 fastened together, a blade holder 7 is mounted between the front and rear protective cases 101 and 102, a front blade net 1 and a rear left-right guide bar 5 are detachably mounted on the blade holder 7, a slider 25 is sleeved on the guide bar 5, and a blade 26 is detachably mounted on the slider 25, in conjunction with fig. 3. The blades 26 together with the slider 25 form a shaving head 2, and the shaving head 2 together with the blade net 1 form a razor of the razor module 10. The rear part of the tool bit 2 is provided with a driving hole 21, the cross section of the driving hole 21 is strip-shaped, and the axis of the cross section is perpendicular to the guide rod 5. The tool holder 7 and the rear protective housing 102 are provided with front and rear alignment holes 22, 23, respectively, at the drive hole 21, so that the drive hole 21 can communicate with the rear drive module 20. Referring to fig. 1 and 4, the driving module 20 includes a protective case 201, a driving motor 4 installed in the protective case 201, a battery 45 for supplying power to the driving motor 4, and a control switch 46 for controlling the connection of the battery 45, the control switch 46 being exposed. In the drive module 20, see fig. 3 and 4, an eccentric shaft 3 protruding forward is mounted on the drive shaft of the drive motor 4, the eccentric shaft 3 is aligned with the drive hole 21 of the cutter head 2, and the drive motor 4 is driven by the eccentric shaft 3 in such a manner as to be connected to the cutter head 2, passing forward through the rear alignment hole 23 and the front alignment hole 22 in sequence and then protruding into the drive hole 21 of the cutter head 2. The beard passes through the meshes of the cutter mesh 1 and stretches into the rear side of the cutter mesh 1, the driving motor 4 drives the eccentric shaft 3 to rotate so as to push the wall of the driving hole 21 of the cutter head 2 laterally, and the cutter head 2 is driven by the driving motor to reciprocate left and right along the guide rod 5 so as to cut off the beard which stretches into the rear side of the cutter mesh 1 together with the cutter mesh 1. Referring to fig. 1 and 4, the razor module 10 can be removed from the drive module 20 upward for cleaning after a long period of use, and the drive hole 21 of the shaving head 2 of the razor module 10 is disengaged from the eccentric shaft 3 after removal.

Referring to fig. 3 and 4, the reciprocating shaver uses the guide rod 5 as a guide member, the cutter head 2 is sleeved on the guide rod 5 and reciprocates laterally along the guide rod 5, and the guide member is positioned at the same position as the cutter head 2 instead of being positioned between the cutter head 2 and the eccentric shaft 3, so that a space is not required to be reserved between the cutter head 2 and the eccentric shaft 3 for placing the guide member. The shaver is characterized in that the driving hole 21 is formed in the shaver head 2, and the eccentric shaft 3 extends into the driving hole 21 to drive and connect the shaver head 2, so that a movable part and an extension rod in the prior art are omitted, and a space is not required to be reserved between the shaver head 2 and the eccentric shaft 3 to place the movable part and the extension rod. The shaver head 2 and the eccentric shaft 3 do not need to leave a space for placing the guide piece, the movable piece and the extension rod as in the prior art, and can be relatively close to each other, so that the volume of the shaver can be relatively small.

Referring to fig. 2, the rear protective housing 102 extends forward and has a mounting post 103, the tool rest 7 is sleeved on the mounting post 103 and can move forward and backward along the mounting post 103, the mounting post 103 is sleeved with a pushing frame spring 8, the pushing frame spring 8 is clamped between the tool rest 7 and the rear protective housing 102, the tool rest 7 is pushed forward, and the upper and lower protective housings 101 and 102 serve as front and rear limiting members respectively and are blocked in front of and behind the tool rest 7 respectively. When the cutter mesh 1 at the front end of the razor module 10 moves on the skin during shaving, when the cutter mesh 1 moves to the skin bulge, the skin bulge applies a backward pushing force to the cutter mesh 1, and the cutter mesh 1 is retracted backward, so that the razor is not easy to scratch the skin bulge. When the cutter mesh 1 moves to the skin concave part, the pushing frame spring 8 pushes the cutter frame 7 forwards to drive the cutter mesh 1 to be close to the skin forwards, so that the shaver can keep a good shaving effect in the skin concave part. Referring to fig. 3, the cutter holder 7 is provided with a top spring portion 71 at the rear side of the cutter head 2, a push cutter spring 6 is sandwiched between the cutter head 2 and the top spring portion 71, and the push cutter spring 6 pushes the cutter head 2 forward to be close to the cutter mesh 1, so that the shaving effect is good. Since the cutter holder 7 is provided with the top spring portion 71, after the cutter head 2 is mounted on the cutter holder 7, an installer can first mount the push cutter spring 6 between the top spring portion 71 of the cutter holder 7 and the cutter head 2, and then cannot mount the push cutter spring 8 on the mounting post 103 until the cutter head 2 is mounted on the mounting post 103 of the rear protective housing 102, that is, the push cutter spring 6 and the push cutter spring 8 are mounted in two steps, so that the mounting is not easy to make mistakes.

The above-described embodiments are provided for the present utility model only and are not intended to limit the scope of patent protection. Insubstantial changes and substitutions can be made by one skilled in the art in light of the teachings of the utility model, as yet fall within the scope of the claims.
