Description

This invention relates to the technical field of eccentric exercise, and in particular to eccentric exercise devices and beauty equipment.

Currently, most motor-driven personal care products use a motor that is directly connected to a brush head to generate rotational or vibrational motion. This type of rotational motion structure is prone to misalignment from the target position, and the lotion or cleansing water is prone to splashing out of the rotational position, and the vibration motion structure is problematic in that it cannot thoroughly cleanse the skin.

The other is a structure disclosed in Chinese invention patent number CN108030427A, which is a swivel movement assembly and a personal cleaning and care device using the same, including a motor, a movement box, an eccentric member, a bearing, a swivel frame, a waterproof rubber ring, a brush head fixing member, and a brush head, the eccentric member and the swivel frame are installed in the movement box, the motor is installed outside the movement box, and the motor is connected to the eccentric member, the central axis of the swivel frame extends outside the movement box, the central axis of the swivel frame is fitted into the eccentric shaft hole of the eccentric member through a bearing, three limiting grooves are provided around the swivel frame, a limiting column is provided on the movement box, the eccentric member is rotated to drive the swivel frame to perform a circular motion with the eccentric amount e as a radius, the waterproof rubber ring is installed between the central axis and the casing, and the central axis passes through the casing and is connected to the brush head. Such a structure has the following defects. On the one hand, the structure is complex, making assembly, disassembly and maintenance difficult; on the other hand, one end of the brush head is connected to the central shaft via a brush head fixing member and is confined within the casing, and a waterproof rubber ring is installed at the junction between the central shaft and the hole in the casing. The waterproof rubber ring can only prevent water from flowing into the casing to which the movement box is attached, but does not achieve the purpose of waterproofing between the brush head and the casing, resulting in poor waterproofing and difficulty in use.

As shown in Figures 1 to 3, the eccentric motion device according to an embodiment of the present invention includes a bracket 7 having an opening, a motor 6, an eccentric member, a bearing 4, and an elastomer 20, the elastomer 20 is fitted around the outer periphery of the bracket 7 to close the opening of the bracket 7, the motor 6, the eccentric member, and the bearing 4 are located in a space formed by the elastomer 20 and the bracket 7, the motor 6 is connected to the bracket 7, the motor 6 is connected to the eccentric member, the output shaft of the eccentric member is connected to the bearing 4, one end of the elastomer 20 located in the space is connected to the bearing 4, and the motor 6 causes the elastomer 20 to perform eccentric circular motion via the eccentric member.

The elastomer 20 has a port portion, and after the port portion is fitted into the opening of the bracket 7, the elastomer 20 closes the opening. The structure of the present invention only includes a bracket, a motor 6, an eccentric member, a bearing 4, and an elastomer 20. The elastomer 20 is fitted around the outer periphery of the bracket 7 to close the opening of the bracket 7, and the motor 6 causes the eccentric member to move eccentrically. The eccentric member 5 drives the bearing 4 to move the elastomer 20. Since the port portion of the elastomer 20 is fitted into the opening of the bracket 7, during the eccentric movement, the connection between the elastomer 20 and the bracket 7 is elastically deformed, and the eccentric circular movement of the elastomer 20 is realized. The structure is simple, the assembly is easy, and the assembly efficiency is improved. During the movement process, the elastomer always closes the opening of the bracket 7 during the eccentric circular movement, improving the waterproof performance and providing a dustproof effect at the same time.

When this device acts on the skin, the eccentric circular motion rubs and kneads the skin, achieving the goal of cleaning the skin. This device moves accurately to the target position and can avoid splashing of lotion or cleanser, improving the user experience.
