[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 6 As shown, this utility model provides a shaver with replaceable blades, which aims to solve the problems of limited functionality and inconvenience of existing reciprocating shavers and vibrating shaving blades. It allows users to experience two different shaving or hair removal methods on the same product, thereby improving the product's usability and convenience.

[0031] The replaceable-head shaver mainly consists of a blade assembly 1, a reciprocating shaver head 2 that can be replaced and mounted on the blade assembly 1, and a vibrating shaving head 3.

[0032] The blade assembly 1 includes a blade housing 11 and a drive motor 12 installed within the blade housing 11. The drive motor 12 provides power for the movement of the blade head. A drive sleeve 13 is fixedly connected to the output shaft of the drive motor 12, and an eccentric shaft head 14 offset from its rotation center is provided at the end of the drive sleeve 13. This eccentric shaft head 14 can convert the rotational motion of the drive motor 12 into reciprocating motion or vibration, thereby driving different types of blade heads to work.

[0033] Reciprocating shaving mode:

[0034] When the reciprocating shaving function is required, the reciprocating shaving head 2 is connected to the end of the blade housing 11. The reciprocating shaving head 2 mainly consists of a first shaving head holder 21, a fixed blade 22, a moving blade 23, and a swing transmission component 24.

[0035] The first shaving head holder 21 is mainly a support structure for the reciprocating shaving head 2. It is detachably connected to the end of the shaving body housing 11 by means of a snap-fit ​​structure or magnetic structure, so that users can easily replace the shaving head.

[0036] Both the fixed blade 22 and the moving blade 23 are mounted on the first blade holder 21. The fixed blade 22 is fixed in place, while the moving blade 23 can reciprocate relative to the fixed blade 22 under the action of the drive mechanism. Through the cooperation between the moving blade 23 and the fixed blade 22, the hair can be effectively cut.

[0037] The oscillating transmission component 24 is the transmission part of the reciprocating shaver head 2, which converts the rotational motion of the drive motor 12 into the reciprocating motion of the moving blade 23. The middle part of the oscillating transmission component 24 is rotatably connected to the first shaver head holder 21 via a rotating shaft. Its lower end is provided with a first U-shaped groove 241, which fits onto the eccentric shaft head 14 of the drive sleeve 13, thereby converting the rotational motion of the eccentric shaft head 14 into the oscillation of the oscillating transmission component 24. The upper end of the oscillating transmission component 24 is also provided with an oscillating head 242, and the moving blade 23 is provided with a second U-shaped groove 231. The oscillating head 242 is inserted into the second U-shaped groove 231, thereby converting the oscillation of the oscillating transmission component 24 into the reciprocating motion of the moving blade 23.

[0038] Vibration scraper mode:

[0039] When the vibratory scraper function is required, the vibratory scraper head 3 is detachably connected to the end of the scraper housing 11. The vibratory scraper head 3 mainly consists of a second scraper head holder 31, a scraper assembly 32, and a vibration transmission component 33.

[0040] The second cutter head holder 31 is mainly a support structure for the vibrating scraper head 3. It is detachably connected to the end of the blade housing 11 by means of a snap-fit ​​structure or magnetic attraction structure, which makes it convenient for users to replace the cutter head.

[0041] The scraper assembly 32 is mounted on the second blade holder 31 and is used to shave hair off the skin surface.

[0042] The vibration transmission component 33 is the transmission part of the vibrating scraper head 3, which converts the rotational motion of the drive motor 12 into the vibration of the scraper assembly 32. Specifically, the lower end of the vibration transmission component 33 is provided with a slot 331, which can be fitted onto the drive sleeve 13 and the eccentric shaft head 14 and cooperates with the drive sleeve 13. In order to prevent the vibration transmission component 33 from rotating circumferentially relative to the drive sleeve 13 during use, a first circumferential limiting structure is provided between the slot 331 and the drive sleeve 13. In this embodiment, the outer side wall of the drive sleeve 13 is polygonal, and the inner side wall of the slot 331 is a polygonal corresponding to the outer side wall of the drive sleeve 13. The two are interlocked to form the first circumferential limiting structure. The upper end of the vibration transmission component 33 is provided with a vibrating eccentric wheel 34. The rotation of the eccentric wheel generates vibration, thereby driving the scraper assembly 32 to vibrate at high frequency, so as to effectively remove hair.

[0043] The following are examples of the detachable connection methods between the first cutter head holder 21, the second cutter head holder 31, and the cutter body housing 11:

[0044] In one embodiment, the first cutter head holder 21 and the second cutter head holder 31 are both connected to the cutter body housing 11 via a snap-fit ​​structure (not shown in the figure). Specifically, the cutter body housing 11 has a slot at its end, and the first cutter head holder 21 or the second cutter head holder 31 has a hook that engages in the slot, thereby achieving a detachable connection between the two.

[0045] In another embodiment, both the first cutter head holder 21 and the second cutter head holder 31 are connected to the blade housing 11 via a magnetic attraction structure. The magnetic attraction structure includes a first magnetic attraction element 15 (such as a ring magnet) located at the end of the blade housing 11 and a second magnetic attraction element 35 (such as a metal ring, which is fixed by screws) located at the end of the second cutter head holder 31. The second cutter head holder 31 is detachably connected to the blade housing 11 through the mutual magnetic attraction between the first magnetic attraction element 15 and the second magnetic attraction element 35.

[0046] To further improve the reliability and stability of the cutter head connection, a second circumferential limiting structure is provided between the first cutter head holder 21 and the cutter body housing 11, and between the second cutter head holder 31 and the cutter body housing 11. In this embodiment, the second circumferential limiting structure includes a non-circular boss 16 and non-circular slots 26 and 36 that are interlocked together. The non-circular boss 16 is located at the end of the cutter body housing 11, and the non-circular slots 26 and 36 are located at the ends of the first cutter head holder 21 and the second cutter head holder 31, respectively. Through the cooperation of the non-circular boss 16 and the non-circular slots 26 and 36, the rotation of the cutter head during use can be effectively prevented, improving the safety of use.

[0047] Working principle:

[0048] When using the reciprocating shaving function, the drive motor 12 is started, which drives the drive sleeve 13 and the eccentric shaft head 14 to rotate. The rotational motion of the eccentric shaft head 14 is converted into the reciprocating motion of the moving blade 23 through the swing transmission component 24, thereby realizing the shaving function.

[0049] When using the vibratory scraper function, the drive motor 12 is started, which drives the drive sleeve 13 and the eccentric shaft head 14 to rotate. The rotational motion of the eccentric shaft head 14 is transmitted to the vibratory eccentric wheel 34 through the vibration transmission component 33. The rotation of the vibratory eccentric wheel 34 generates vibration, thereby driving the scraper assembly 32 to vibrate at high frequency to achieve the scraping function.

[0050] By changing different blades, users can experience both reciprocating shaving and vibrating scraping functions on the same shaver, meeting diverse grooming needs.
