Description

Technical Field

[0001] This utility model relates to the field of depilatory razor technology, and in particular to a floating assembly for a manual depilatory razor head. Background Technology

[0002] A manual razor is a personal care tool that removes hair manually, primarily used to remove unwanted hair from various parts of the body.

[0003] Traditional manual razors mostly use a fixed blade design, with a single contact angle between the blade and the skin, which is difficult to adapt to the complex curves of different parts of the body. Especially in areas with uneven skin, the rigid blade is prone to insufficient contact, resulting in cutting residue or excessive local pressure, causing problems such as skin redness, swelling, and scratches.

[0004] Therefore, this utility model provides a floating component for the head of a manual depilatory razor. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a floating assembly for a manual hair removal razor head.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a manual depilatory razor head floating assembly, including a housing assembly, the housing assembly including a front locking block, a blade support being movably connected inside the front locking block, a locking frame being provided on the outside of the blade support, and a handle connecting seat being provided on the outside of the locking frame;

[0007] A floating bonding assembly includes an inner horizontal plate fixedly connected inside the card frame, and spring pieces are fixedly connected to the four outer corners of the inner horizontal plate.

[0008] In a preferred embodiment, a handle is fixedly connected to the end of the handle connector away from the card frame, and a blade protection cover is fitted onto the end of the housing assembly of the card frame away from the handle connector.

[0009] In a preferred embodiment, a plurality of hook blocks are fixedly connected to the outer side of the front locking block near the blade bracket, and a hook plate is fixedly connected to the end of the blade bracket near the locking frame.

[0010] In a preferred embodiment, the handle connector has several mounting slots arranged in a circular array inside.

[0011] In a preferred embodiment, the outer side of the hook block engages with the mounting slot, and the outer side of the hook plate engages with the mounting slot.

[0012] In a preferred embodiment, the front locking block is fixedly connected to the handle connecting seat via a locking hook block, and the blade holder is fixedly connected to the handle connecting seat via a hook plate.

[0013] In a preferred embodiment, the end of the spring piece away from the card frame contacts the interior of the handle connector.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] This invention allows the user to apply pressure by gripping the handle, causing the blade holder to slide linearly along the guide track of the front locking block. This, in turn, causes the hook plate to move within the mounting slot of the handle connector, compressing and deforming the inner spring sheet of the locking frame. This, in turn, causes the blade head to float and automatically adjust its tilt angle according to the skin's curvature. This design achieves the effects of dynamic floating of the blade head with the skin's curvature, multi-directional micro-tilt fit, and automatic reset. The elastic deformation of the spring sheet evenly buffers the pressure, while the locking and limiting action of the hook block and the mounting slot ensures stable sliding. This solves the problems of difficulty in adapting to the complex curvature of the human body, insufficient fit leading to cutting residue, and excessive local pressure. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 - Figure 2 As shown, this embodiment provides a technical solution: a manual hair removal razor head floating assembly, including a housing assembly 1, the housing assembly 1 including a front locking block 11, a blade support 12 movably connected inside the front locking block 11, a locking frame 13 provided on the outside of the blade support 12, a handle connecting seat 14 provided on the outside of the locking frame 13, a handle 15 fixedly connected to the end of the handle connecting seat 14 away from the locking frame 13, and a razor head protective cover 16 sleeved on the end of the housing assembly 1 away from the handle connecting seat 14;

[0024] The front locking block 11 is internally connected to the blade support 12, providing a guide track for the blade support 12 to move in a straight line, limiting its movement trajectory, and ensuring the stability of the blade head when floating. The blade support 12 carries the blade and achieves the purpose of sliding through the movable connection with the front locking block 11. Under the action of external force, it drives the blade head to slide along the housing assembly 1, realizing the floating function. The outer side of the locking frame 13 is connected to the handle connecting seat 14, and the inner side is fixed to the blade support 12 through the buckle, forming an integration of the blade head base and the elastic device. The handle connecting seat 14 serves as the connector between the locking frame 13 and the handle 15, transmitting the gripping force and being fixed to the housing assembly 1 through the buckle. The handle 15 is a support structure that provides a grip for the user, making it easy to control the movement of the blade head. The blade head protective cover 16 is sleeved on the front end of the housing assembly 1, covering the blade head area, preventing the blade from accidentally contacting foreign objects when not in use, which could cause damage or safety hazards.

[0025] like Figure 1 - Figure 3 As shown, the floating bonding component 2 includes an inner horizontal plate 21 fixedly connected inside the card frame 13. Spring pieces 22 are fixedly connected to the four outer corners of the inner horizontal plate 21. The end of the spring piece 22 away from the card frame 13 contacts the interior of the handle connecting seat 14. Several hook blocks 23 are fixedly connected to the outer side of the front card block 11 near the blade bracket 12. A hook plate 24 is fixedly connected to the end of the blade bracket 12 near the card frame 13. Several mounting slots 25 are arranged in a circular array inside the handle connecting seat 14. The outer sides of the hook blocks 23 engage with the mounting slots 25, and the outer sides of the hook plates 24 engage with the mounting slots 25. The front card block 11 is fixedly connected to the handle connecting seat 14 via the hook blocks 23, and the blade bracket 12 is fixedly connected to the handle connecting seat 14 via the hook plates 24.

[0026] The inner horizontal plate 21 serves as the supporting skeleton inside the frame 13, fixing the installation position of the spring piece 22 and ensuring that the spring piece 22 maintains a stable deformation direction when subjected to force. It also provides lateral restraint for the blade holder 12, preventing it from shifting during floating. Utilizing the elastic properties of the plastic material, when the blade holder 12 is compressed by external force, the spring piece 22 deforms, causing the blade head to float along the guide track of the front locking block 11. When the external force disappears, the spring piece 22 resets, driving the blade head back to its original position. Furthermore, through a symmetrical design at the four corners, the pressure on the blade head is evenly transmitted to the handle connecting seat 14, ensuring that the blade head remains horizontal during floating. The four corner spring pieces 22 form an elastic matrix, allowing the blade head to move freely with the surroundings. The skin surface is slightly tilted up, down, left, and right to improve the fit accuracy during hair removal. The design of the hook block 23 allows the front hook block 11 to engage with the mounting slot 25 of the handle connector 14 through the outer hook block 23, realizing the detachable fixation of the front hook block 11 and the handle connector 14. At the same time, the design of the sliding track hook plate 24 for the blade holder 12 allows the blade holder 12 to engage with the mounting slot 25 of the handle connector 14 through the hook plate 24, so that the blade holder 12 will not fall off the front hook block 11 when it floats with the blade head. The design of the mounting slot 25 is adapted to the hook block 23 and the hook plate 24 to realize the integrated fixation of the front hook block 11, the blade holder 12 and the handle connector 14.

[0027] Working principle:

[0028] like Figure 1 - Figure 3 As shown:

[0029] In use: First, when the user holds the handle 15 and applies pressure, the blade holder 12 slides linearly along the guide track of the front locking block 11 under the action of external force, which in turn drives the hook plate 24 to move synchronously in the mounting slot 25 of the handle connector 14; at this time, the spring piece 22 on the inner side of the frame 13 is compressed and deformed by the thrust of the blade holder 12, which can drive the blade head to float along the direction of the housing assembly 1, so that the blade can automatically adjust the tilt angle according to the skin curvature. The elastic deformation of the spring piece 22 evenly transmits the pressure to the handle connector 14, thereby driving the blade head to tilt slightly in the up, down and left and right directions. At the same time, the locking and limiting of the hook block 23 and the mounting slot 25 ensures that the sliding trajectory of the front locking block 11 and the blade holder 12 is stable; after the external force is released, the spring piece 22 rebounds and resets, pushing the blade holder 12 back to the initial position along the guide track, and finally realizing the dual functions of floating head fitting and automatic reset, improving the skin fit during hair removal.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
