Technical Field

[0001] The present invention relates to the field of daily necessities, and in particular to a high-freedom universal shaver and a floating mechanism of a shaving unit thereof. Background Art

[0002] Razors are very common in our daily life and are even a must-have item for every man. There are many types of razors, including non-electric, electric, with fixed heads and with rotating heads.

[0003] In electric shavers, most shaving units are fixedly connected to the supporting structure, that is, the shaving unit cannot move relative to the supporting structure, and the blade head assembly on the shaving unit rotates under the drive of the internal transmission structure to perform shaving operations. Although this structure can meet shaving needs, when the shaving unit moves on the skin surface, there is a stiff conflict between the shaving unit and the skin, and the shaving force is entirely dependent on the hand grip strength of the human hand to adjust. That is, when the shaving unit feels that the contact with the skin is too tight, the human hand presses the shaver loosely, otherwise, press it tighter. During the entire shaving process, the hand is in a tense state. After shaving is completed, there may be a sore feeling, and the user experience is extremely poor.

[0004] Of course, there are many rotating razors on the market. Some shaving units use a cross-type universal joint to achieve rotation between the shaving unit and the supporting structure. However, such a structure is cumbersome to assemble, and the defect rate increases. In addition, the flexibility of this rotating structure is not high, and the problem of weak adaptability between the shaving unit and the skin is not fundamentally solved, and a good user experience cannot be provided.

[0005] In summary, existing shavers require manual adjustment of the distance between the shaving unit and the skin, and the adaptability between the shaving unit and the skin is not strong, which is laborious and results in a poor shaving experience. Summary of the Invention

[0058] The present invention provides a shaving unit floating mechanism, which comprises:

[0059] The fixing seat 61 is provided with a first connecting hole 71 for receiving the connector 4;

[0060] The connector 4 is supported on the fixing seat 61 through the first connecting hole 71 , and the connector 4 has a guiding inclined surface 51 in the movable direction;

[0061] n guide members 3 , each of which is equipped with an elastic element 2 and is received in the fixing seat 61 , and moves relative to the guide surface 5 , where n=1, 2, 3, 4, 5, etc.;

[0062] The upper cover 1 is provided with a guide channel 11 in the closing direction of the upper cover 1, which cooperates with the guide boss 313 to ensure that the guide member 3 moves on the corresponding track;

[0063] The guide member 3 defines a guide matching inclined surface 311 that matches the guide inclined surface 51 , and a movable gap 3111 is provided below the contact point between the guide inclined surface 51 and the guide matching inclined surface 311 and below the upper cover 1 .

[0064] Specifically:

[0065] The fixed seat 61 is placed in the annular cavity of the base 62, and the first connecting hole 71 of the fixed seat 61 corresponds to the second connecting hole 72 of the base 62. The connector 4 passes through the first connecting hole 71 of the fixed seat 61 and the second connecting hole 72 of the base 62. The guide rib 3121 cooperates with the guide groove 611 to perform relative movement during guidance. In a preferred embodiment of the present invention, the guide member 3 is an integrated structure composed of three guide blocks 31, which is convenient for assembly with the connector 4. The guide matching bevel 311 of the guide block 31 is in close contact with the guide bevel 51. The three guide blocks 31 are "Z"-shaped structures with conical protrusions. There is a movable gap 3111 below the contact point between the fixed seat 61 and the connector 4 in the diameter direction and below the upper cover 1. When the guide block 31 moves along the guide bevel 51, the entire shaving unit can float up and down, swing 360 degrees, and translate 360 ​​degrees within a small range. The guide block 31 has a guide boss 313, and the side portions of the three guide bosses 313 are extended and connected to form an integrated structure, which is convenient for installation with the joint 4, and the tail of the guide block 31 is a vacant structure, which is convenient for installing one end of the spring 21, and the other end of the spring 21 enters the mounting groove of the fixing seat 61 along the elastic direction. The number of the springs 21 is consistent with the number of the guide blocks 31, and a plurality of guide ribs 3121 extend from the upper surface of the guide boss 313 in the reset direction of the spring 21. In a preferred embodiment of the present invention, the number of the guide ribs 3121 is consistent with the number of the guide blocks 31, and the guide ribs cooperate with the guide grooves 611 to ensure that the guide block 31 moves in the corresponding track direction.

[0066] In addition, the guide blocks 31 include but are not limited to three, and can also be four, five, etc. The guide blocks 31 move a certain distance along the guide slope 51 and are reset by the spring 21. It is worth noting here that the elastic element 2 is not limited to the spring 21, such as a stainless steel shrapnel, etc. The guide block 31 can also be directly made of plastic elastic material, which itself has an elastic reset function.

[0067] The whole process of floating is:

[0068] The joint 4 is fixed on the supporting structure, and the entire head can move up and down, swing (tilt) 360 degrees, rotate at a certain angle, and translate in a small range. After assembly, a movable gap 3111 is left between the joint 4 and the upper cover 1 in the up and down directions, and a movable gap 3111 is left between the joint 4 and the fixing seat 61 in the diameter direction. When the head floats, (the joint 4 is provided with a guide bevel 51, and the corresponding guide block 31 is provided with a guide matching bevel 311, and the guide bevel 51 is conical in the present invention, including but not limited to a conical shape) the guide bevel 51 on the joint 4 acts to move the guide block 31 outward, and the guide block 31 is reset by the spring 21. The guide block 31 pushes the joint 4 through the guide bevel 51, and finally the head is reset.
