Description

Stepless flapping mechanism of skin beautifying device

The present invention relates to a stepless flapping mechanism of a skin beautifying device, and particularly refers to a reciprocating flapping mechanism with simple structure and high durability.

Traditionally known facial massage devices are mostly based on the principle of vibration massage. They use slight vibrations to stimulate facial skin to promote blood circulation and delay facial skin aging. In recent years, industry studies have found that this type of vibration massage cannot achieve facial skin massage. The lifting effect will make the connective tissue of the skin soft and prone to wrinkles. To solve this problem, the industry has developed a slap-type skin beautification device to replace the traditional vibrating facial massage device.

Please refer to Figures 1 to 3, in addition to the housing (20), the control circuit board (30) and the drive motor (50), the common flapping skin beautification device mainly uses a massage unit (40) to provide a The thrust (as shown in Figure 1) produces a skin-lifting effect on facial massage. Simply put: the massage unit (40) must at least include a linking rope (60), a moving part (42), and a combined seat (41), wherein the upper half of the coupling seat (41) has two parallel transmission parts (411), (412), and the space generated between the two transmission parts (411) and (412) is for the movement The member (42) reciprocates up and down, and the lower half of the coupling seat (41) is for the motor (50) to be fixed, so that the output end (51) of the motor (50) can be extended to the transmission part (411), ( 412) (as shown in Figure 2), the output end (51) of the motor (50) uses a sheave (52) to drive the aforementioned draw rope (60) to pull a moving part (42) between the two transmission parts ( 411) and (412) (as shown in Figure 3), so that a properly shaped massage head (70) installed at the upper end (43) of the moving part (42) Thrust massage the face to produce skin lifting effect.

Please refer to Figures 2 to 3 again, where the two ends of the pull rope (60) are respectively fixed to the motor (50) sheave (52) and the fixing groove (417) of the transmission part (411). (60) The middle section is wound on the first roller (413), the second roller (414), the third roller (422), and the fourth roller (415) (as shown in Figure 2), where the third roller (422) ) Is used to link the moving member (42) to move up and down, and the third roller (422) is arranged between the second roller (414) and the fourth roller (415);

When the motor (50) rotates forward, its output end (51) rotates the rope pulley (52) to wind the rope (60), and the rope (60) between the second roller (414) and the fourth roller (415) is tight And push the third roller (422) so that the third roller (422) moves the moving part (42) upward (as shown in Figure 3). When the motor (50) reverses or does not work, the second roller (414) The draw rope (60) between) and the fourth roller (415) relaxes accordingly, and the movable member (42) uses its own elastic force and its gravity to move downward to reset (as shown in Figure 2).

The composition of the aforementioned flapping skin beautification device is too complicated, resulting in high assembly costs, and the device uses a drawstring (60) to be wound on multiple rollers to pull a single moving part (42), except that the drawstring (60) is easy The thread is easily broken due to repeated pulling and resistance friction, and the user exerts too much pressure on the massage head (70), which may cause the third roller (422) to over-stress the corresponding draw rope (60) and cause the thread to break In addition, the above-mentioned structure will inevitably cause the overall skin beautifying device to be too bulky, which seems to be a great limitation for today's electronic products that are thin and short.

How to effectively simplify the components of the skin beautification device and simultaneously have high durability is the subject of the present invention.

The main purpose of the present invention is to provide a stepless flapping mechanism of a skin beautification device, which utilizes a central drive shaft to drive a reciprocating sleeve so that the reciprocating sleeve is driven by the central drive shaft Drive upward displacement, so that the elastic shaft at the upper end of the reciprocating sleeve can provide an upward pushing force to massage the face to produce skin lifting effect, and then use the elastic force accumulated upward by the elastic shaft itself to reverse (downward) reciprocating The sleeve is pushed back to reset, and then achieves the slap effect produced by moving to the reset.

The present invention mainly provides a stepless flapping mechanism of a skin beautifying device. The mechanism includes at least one power source, at least one reduction gear set and at least one reciprocating mechanism, wherein the power source provides an intermittent power to the reduction gear The reciprocating mechanism is decelerated by a reduction gear set and drives the reciprocating mechanism to perform intermittent movement, wherein the reciprocating mechanism at least includes: a central drive shaft driven by the reduction gear set; The shaft is driven by the central drive shaft to move upward; an elastic shaft is fixed at the upper end of the reciprocating sleeve; an outer cylinder is sleeved with the reciprocating sleeve and the elastic shaft, and the outer cylinder and the An elastic element is arranged between the elastic shafts. The elastic element is used to accumulate the energy of the upward displacement of the reciprocating sleeve, and the reciprocating sleeve is pushed back and reset by the elastic shaft; thereby, the reciprocating sleeve is driven to rotate by the central drive shaft When the reciprocating sleeve is guided by the central drive shaft or the outer cylinder to move up to a distance, the elastic shaft at its end is synchronously raised a distance, and the elastic element reverses the reciprocating sleeve to return Push reset.

According to the above-mentioned main feature, the central drive shaft is a twisted spiral pattern for guiding the reciprocating sleeve to move upward for a distance.

According to the aforementioned main feature, the outer cylinder is a cam cylinder with a progressive slide, and the reciprocating sleeve extends corresponding to the guide shaft of the progressive slide. When the reciprocating sleeve is driven by the central drive shaft When rotating, the guide shaft of the reciprocating sleeve is guided by the progressive slide rail of the cam cylinder to move upward to a distance, and then the end elastic shaft is synchronously raised.
