Abstract
Description
Technical Field
[0001] The utility model relates to the field of beauty equipment, in particular to a microcrystal introduction instrument with stable transmission. Background Art
[0002] With improved living standards, people's demand for skin care and beauty is growing. Traditional skin care methods, such as application and massage, can improve skin condition to a certain extent. However, due to the barrier of the skin's stratum corneum, the active ingredients in skin care products often have difficulty penetrating deeper into the skin, resulting in limited effectiveness. In recent years, with the continuous development of nanotechnology, its application in the field of skin care has become increasingly widespread. Microdermabrasion devices are a typical nanotechnology product. They use extremely fine needles on a chip to penetrate the barrier layer on the human surface, opening millions of channels in the epidermis over an area of several square millimeters without damaging the epidermis. These channels allow nutrients to effectively penetrate the skin, stimulating collagen proliferation and cell regeneration, and repairing aging cells. This can achieve the effects of reducing wrinkles, treating scars and stretch marks, whitening the skin, fading dark spots, improving eye wrinkles and dark circles, and tightening and lifting facial skin tissue.
[0003] While existing micro-crystal delivery devices have addressed the issue of skincare product absorption to some extent, most use an eccentric shaft or cam to convert the motor's rotational motion into the reciprocating motion of the microneedles. During use, the high-speed rotation of the eccentric shaft or cam can easily cause the device to vibrate or shake, affecting the stability and accuracy of the microneedles, while also reducing the delivery effect and user experience. Therefore, the present invention proposes a micro-crystal delivery device with a stable transmission. Summary of the Invention

One end of the sleeve is provided with a push rod that cooperates with the microneedle head. The cylindrical cam is connected and cooperated with one end of the motor. The outer side of the cylindrical cam is provided with mutually staggered sliding grooves. The sleeve is installed with a sliding block that cooperates with the sliding groove through a pin.

DETAILED DESCRIPTION
[0025] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.
[0026] In this embodiment, refer to Figures 1-9 The invention specifically implements a microcrystal introduction instrument with stable transmission, characterized in that it includes a housing 1, a power assembly installed in the housing 1, a fine-tuning assembly installed at one end of the housing 1, a microneedle head 2 cooperating with the power assembly installed in the fine-tuning assembly, and a power assembly including a motor 3, a slidable sleeve 4, and a rotatable cylindrical cam 5. The motor 3 is fixedly installed in the housing 1, and one end of the sleeve 4 is provided with a push rod 6 cooperating with the microneedle head 2. The cylindrical cam 5 is connected to one end of the motor 3. The outer side of the cylindrical cam 5 is provided with mutually staggered sliding grooves 7. The sleeve 4 is equipped with a sliding block 9 cooperating with the sliding groove 7 through a latch 8. The motor 3 and the cylindrical cam 5 are connected by a key block so that the rotational motion of the motor 3 can be effectively transmitted to the cylindrical cam 5. The mutually staggered sliding grooves 7 allow the motor 3 to achieve the reciprocating motion of the sliding block 9 with only one-way rotation. The rotation of the cylindrical cam 5 drives the sliding block 9 to reciprocate within the sliding groove 7, which in turn causes the push rod 6 on the roller to reciprocate, pushing the microneedle head 2 for precise microcrystal introduction. This improves the stability and accuracy of the microneedle head 2, enhancing the precision and effectiveness of microcrystal introduction. The well-matched dimensions of the sliding groove 7 and the sliding block 9 make the transmission process smoother and more precise, thereby reducing the vibration and jitter caused by the high-speed rotation of the motor 3.
[0027] Furthermore, a stopper 10 is provided on the outside of the sleeve 4, and a stopper groove 11 is provided on the housing 1 to cooperate with the stopper 10. The design of the stopper 10 and the stopper groove 11 ensures that the sleeve 4 can only slide back and forth along the stopper groove 11, preventing the sleeve 4 from rotating with the cylindrical cam 5, which would affect the normal operation of the introduction instrument. Lubricating oil can be added between the stopper 10 and the stopper groove 11 to reduce friction, thereby ensuring smooth movement of the sleeve 4.
[0028] Furthermore, a support frame 12 for mounting the motor 3 is provided within the housing 1. The motor 3 is secured to the support frame 12 via screws. One end of the support frame 12 is provided with a protrusion 13 that engages with the retaining groove 11. The other end engages with the rear cover of the housing 1, forming a stable support structure between the support frame 12 and the housing 1. The protrusion 13 of the support frame 12 engages with the retaining groove 11 of the housing 1, securing the support frame 12 in a fixed position within the housing 1, thereby ensuring stable operation of the motor 3.
[0029] Furthermore, a circuit board 14 and a battery 15 are mounted on the support frame 12. The circuit board 14 is electrically connected to the battery 15 and the motor 3, respectively. A button 16 for cooperating with the circuit board 14 is provided on the outside of the housing 1. The circuit board 14 and the battery 15 are both fixed to the support frame 12 by screws, ensuring the stability and safety of the circuit board 14 and the battery 15. The connection between the circuit board 14, the battery 15, and the motor 3 ensures the normal operation of the power supply and control system of the microcrystal introduction instrument. The button 16 is arranged on the outside of the housing 1 and controls the opening and mode switching of the microcrystal introduction instrument through the connection with the circuit board 14, thereby meeting the different needs of users.
[0030] Furthermore, the fine-tuning assembly includes a rotatable adjustment knob 17, an adjustment sleeve 18 slidably mounted within the adjustment knob 17, and a stop sleeve 19 fixed to one end of the adjustment knob 17. The adjustment knob 17 has a groove on its outer side, within which a ferrule is located. The ferrule and housing 1 have corresponding threaded holes, allowing the screw and ferrule to engage while simultaneously securing the adjustment knob 17 to one end of the housing 1 and allowing for rotational movement. The adjustment sleeve 18 is threadedly engaged with the adjustment knob 17, and the stop sleeve 19 limits its sliding range, ensuring precise adjustment of the microneedle head 2.
[0031] Furthermore, the adjustment sleeve 18 is provided with a slot 20, and the microneedle head 2 is provided with a block 21 that cooperates with the slot 20. The design of the slot 20 and the block 21 allows the microneedle head 2 to be quickly installed on the adjustment sleeve 18, and the adjustment knob 17 allows for precise adjustment of the microcrystal insertion depth. The double-layer contact design between the slot 20 and the block 21 improves the stability and positioning accuracy of the microneedle head 2.
[0032] Furthermore, sleeve 4 is provided with reinforcing ribs 22. These ribs enhance the sleeve's structural strength and rigidity, ensuring it can withstand greater forces without deformation during microcrystal introduction. The provision of these ribs not only enhances the overall durability of the device but also effectively reduces fatigue damage from prolonged use, thereby extending the lifespan of the microcrystal introduction device.
[0033] The beneficial effects of this utility model are as follows: through the cooperation between the sliding block 9 and the sliding groove 7 on the cylindrical cam 5, the rotational motion of the motor 3 is converted into the reciprocating sliding motion of the sleeve 4, while maintaining high stability, effectively reducing vibration and jitter, and improving the accuracy and stability of the microneedle head 2. The interlaced sliding grooves 7 also make the movement of the sliding block 9 smoother and more fluid, thereby improving the user experience of the microcrystal introduction device.
