Detailed Implementation

[0034] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0038] A hair removal device includes a blade head 1 and a main unit. The blade head 1 includes a blade head seat 11 disposed at the bottom. The main unit includes a front cover 2 and a rear cover 3, which form a hollow installation space. A disassembly structure for the hair removal device blade head 1 is disposed between the blade head 1 and the main unit.

[0039] The disassembly structure includes a receiving member 4 fixed to the top of the installation space. The receiving member 4 is hollow inside and has an opening on one side. The sliding plate 5 is slidably locked inside the receiving member 4 by an anti-detachment structure. A compression spring 6 connected to the receiving member 4 is provided at the end of the sliding plate 5 away from the opening of the receiving member 4. A button 7 is provided at the end of the sliding plate 5 near the opening of the receiving member 4. The button 7 is located in the mounting hole 31 of the rear cover 3 and has a hook 71 extending into the opening of the receiving member 4 and connected to the sliding plate 5. The bottom of the blade holder 11 is formed with a pin 12 that is provided to the sliding plate 5. The sliding plate 5 is formed with a hole 51 that cooperates with the pin 12 to lock the blade 1.

[0040] The upper surface formed by the combination of the front cover 2 and the rear cover 3, as well as the accommodating member 4, are respectively provided with through holes 42 corresponding to the insertion hole 51. The pin 12 can be connected to the insertion hole 51 through the through holes 42 on the upper surface and the accommodating member 4, respectively.

[0041] The blade 1 is aligned with the host, the socket 51 passes through the through hole 42 on the upper surface and the through hole 42 of the receiving member 4, and abuts against the sliding plate 5. The blade 1 continues to press down, and the sliding plate 5 squeezes the compression spring 6, causing the socket 51 to move in the direction of the compression spring 6, allowing the pin 12 to pass through. Then the compression spring 6 returns to its original position, causing the socket 51 to move in the opposite direction of the compression spring 6 to lock the pin 12. When unlocking, the button 7 is pressed, and the hook 71 pushes the sliding plate 5 inward, the socket 51 unlocks the pin 12, and the blade 1 is detachable.

[0042] The above structure uses the receiving member 4 to house the sliding plate 5 and the compression spring 6, and then fixes the receiving member 4 in the installation space. The sliding plate 5 is restricted to move within the receiving member 4. In addition, the button 7 is directly connected to the sliding plate 5. Compared with the prior art, the structure is more robust, has better stability, and is not easily damaged.

[0043] Two compression springs 6 are provided. A fixing rod 58 is provided on the side of the sliding plate 5 where the compression spring 6 is located. The compression spring 6 is sleeved on the fixing rod 58. This structure effectively restricts the compression spring 6 between the sliding plate 5 and the receiving member 4, preventing the compression spring 6 from detaching.

[0044] The sliding plate 5 is slidably engaged within the accommodating member 4 via an anti-detachment structure. The anti-detachment structure includes an anti-detachment tongue 53 with a sliding hole on the sliding plate 5. An anti-detachment protrusion 54 is formed upward at the end of the anti-detachment tongue 53. An anti-detachment hole 41 is provided in the accommodating member 4 at a position relative to the anti-detachment tongue 53. The anti-detachment protrusion 54 is placed in the anti-detachment hole 41 and can move back and forth within the anti-detachment hole 41. The inward-facing side of the anti-detachment protrusion 54 is provided as a slope to facilitate the entry of the anti-detachment protrusion 54 into the anti-detachment hole 41.

[0045] The anti-detachment structure can restrict the sliding plate 5 within the accommodating member 4, preventing the sliding plate 5 and the compression spring 6 from coming out, without affecting the movement of the sliding plate 5 within the accommodating member 4, and can form an integral part with the accommodating member 4, which is convenient for assembly.

[0046] The rear cover 3 has a mounting hole 31 at a position relative to the receiving member 4. The button 7 passes through the mounting hole 31 and connects to the sliding plate 5. Two hooks 71 are provided, facing each other. The sliding plate 5 has a groove 52 for engaging with the hooks 71. During assembly, the button 7 is inserted through the mounting hole 31, and the hooks 71 are pushed in along the groove of the groove 52 and locked in place. In this structure, the button 7 is directly connected to the sliding plate 5, which is firm and reliable.

[0047] The button 7 is also provided with a limiting protrusion 72 between the two plug-in parts, and the sliding plate 5 is provided with a limiting groove 56 at the corresponding position. The limiting protrusion 72 is inserted into the limiting groove 56. This structure can prevent the button 7 from shifting up and down and ensure that the hook 71 is located in the slot 52.

[0048] The sliding plate 5 has multiple raised ribs 55 on its upper and lower surfaces. These raised ribs 55 can contact the inner wall of the accommodating member 4, thereby reducing the friction between the sliding plate 5 and the accommodating member 4.

[0049] The two sides of the accommodating member 4 are provided with fixing protrusions 43; the top of the front cover 2 and the rear cover 3 are respectively provided with fixing grooves 32 suitable for the top corners of the fixing protrusions 43 on both sides to be inserted and locked. The fixing groove of the front cover 2 is located in a position similar to the fixing groove 32 of the rear cover 3. This structure fixes the accommodating member 4 in the installation space to prevent shaking.

[0050] The bottom of the inner sidewalls on both sides of the receiving member 4 is formed with positioning grooves 44, and the sliding plate 5 is provided with positioning protrusions 57 on opposite sides. The positioning protrusions 57 are inserted into the positioning grooves 44 to quickly position the sliding plate 5 and prevent it from being installed upside down.

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
