A reciprocating drive mechanism for a microcrystalline nanoparticle induction instrument

Abstract

This utility model discloses a reciprocating drive mechanism for a microcrystalline nanoparticle induction instrument, belonging to the technical field of microcrystalline nanoparticle induction instruments. It includes a motor body, with a fan-shaped eccentric sleeve to increase the weight of the eccentric block during rotation. This increases the inertial force during eccentric rotation and reduces vibration caused by eccentricity. The connection between the first and second bearings ensures smoother movement of the linkage rod, motor eccentric sleeve, and drive rod, reducing noise from friction and increasing the lifespan of the mechanism. The linkage rod is directly fixed to the motor eccentric sleeve using an anti-loosening screw passing through the first bearing, and then the first bearing is secured with a washer screw to prevent it from detaching from the linkage rod. The other end of the linkage rod is connected to the drive rod in the same way. This simplifies the structure, reduces the size of the mechanism, and reduces the wobbling of the linkage rod during reciprocating motion, thereby reducing handle vibration.

Description

Technical Field

[0001] This utility model relates to the field of microcrystalline nanoparticle induction instrument technology, specifically to a reciprocating drive mechanism for a microcrystalline nanoparticle induction instrument. Background Technology

[0002] Currently, in the beauty industry, microneedles on nanochips are used to open skin channels. The needles are distributed across the nanochips. Due to the extreme size of the microneedles, users experience almost no sensation when they act on the skin, allowing for non-invasive delivery of solutions deep into the skin for better absorption. However, this requires a high-frequency reciprocating mechanism. By moving the microneedles into contact with the user's face, it automatically opens skin channels and injects the treatment solution. The high-frequency contact between the microneedles and the face instantly creates numerous micropores, injecting the treatment solution into the skin before the micropores close, thus achieving a cosmetic effect.

[0003] In existing technologies, current reciprocating drive mechanisms for nanocrystalline nanoparticles use turbines and cam mechanisms. However, due to the high-frequency motion, the turbine-based steering and deceleration methods suffer from short lifespans due to wear during high-speed turbine operation. Cam mechanisms rely on springs for reset, which also experience lifespan reduction as the springs' lifespan may not be sufficient. Furthermore, the impact force of these solutions depends on the motor torque; most currently used motors are brushed, resulting in weak impact force and a tendency to jam. Moreover, current reciprocating drive structures cannot adjust the stroke according to the user's skin tightness. This means that for clients with looser skin, the microcrystals, with a fixed push stroke, cannot effectively deliver the solution into the deeper layers of the skin. Therefore, this device provides a reciprocating drive mechanism for a microcrystalline nanoparticle delivery instrument. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a reciprocating drive mechanism for a microcrystalline nanoparticle induction instrument, thereby solving the aforementioned technical problems.

[0006] A first bearing is provided at the connection between the linkage rod and the eccentric sleeve of the motor, and a second bearing is provided on the inner side of the linkage rod. One side of the second bearing is rotatably mounted to the drive rod.

[0007] As a further improvement to the above solution, an adjustment knob seat is fixedly installed on one side of the drive rod, and an adjustment knob is rotatably installed on the outer side of the adjustment knob seat.

[0009] As a further improvement to the above solution, a magnet is provided on one side of the microcrystalline fixing rod and the driving rod, and a buckle is provided at the connection between the microcrystalline head and the adjustment knob seat.

[0010] As a further improvement to the above solution, a threaded hole is provided at the connection between the linkage rod, the first bearing, and the second bearing, and a fixing bolt is installed on the inner thread of the threaded hole.

[0014] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0015] 1.

The connection between the first and second bearings makes the linkage rod, motor eccentric sleeve and drive rod move more smoothly, reducing the noise generated by the friction of the mechanism and increasing the service life of the mechanism.

[0016] 2. The linkage rod is directly fixed to the eccentric sleeve of the motor by passing through the first bearing with an anti-loosening screw, and then the first bearing is fixed with a washer screw to prevent it from falling off the linkage rod; the other end of the linkage rod is connected to the drive rod in the same way; this simplifies the structure, reduces the size of the mechanism, and reduces the wobbling of the linkage rod during reciprocating motion, thereby reducing the vibration of the handle.

[0025] The following is in conjunction with the appendix Figure 1-4 This document provides a detailed description of the technical solutions provided in each embodiment of the present invention.

[0026] This utility model embodiment provides a reciprocating drive mechanism for a microcrystalline nano-introduction instrument, including a motor bracket 2, a motor body 1 fixedly installed on the inner side of the motor bracket 2, a motor eccentric sleeve 3 fixedly installed on the output end of the motor body 1, and a linkage rod 4 provided on the front side of the motor eccentric sleeve 3.

[0027] A first bearing 5 is provided at the connection between the linkage rod 4 and the eccentric sleeve 3 of the motor, and a second bearing 6 is provided on the inner side of the linkage rod 4. One side of the second bearing 6 is rotatably mounted to the drive rod 7.

[0028] In a further preferred embodiment of this utility model, an adjustment knob seat 9 is fixedly installed on one side of the drive rod 7, and an adjustment knob 8 is rotatably installed on the outer side of the adjustment knob seat 9.

[0029] Furthermore, when the motor body 1 starts, it drives the motor eccentric sleeve 3 to rotate around the motor body 1. One end of the linkage rod 4 is eccentrically connected to the motor eccentric sleeve 3. Therefore, the rotation of the linkage rod 4 drives the drive rod 7 to make linear reciprocating motion under the guidance of the adjustment knob seat 9. In a further preferred embodiment of this utility model, a microcrystalline fixing rod 11 is fixedly installed on one side of the adjustment knob seat 9, and a microcrystalline head 10 is fixedly installed on the outer side of the microcrystalline fixing rod 11.

[0030] Furthermore, the user can adjust the distance between the end face of the microcrystalline head 10 and the microcrystalline chip on the microcrystalline fixing rod 11, so that the actual stroke of the microcrystalline chip and the microcrystalline head 10 on the handle can be adjusted according to the tightness of the user's skin during reciprocating motion.

[0031] In a further preferred embodiment of this utility model, a magnet 12 is provided on one side of the microcrystalline fixing rod 11 and the driving rod 7, and a buckle is provided at the connection between the microcrystalline head 10 and the adjusting knob seat 9.

[0032] Furthermore, the microcrystalline fixing rod 11 passes through the microcrystalline head 10, and the microcrystalline head 10 has a buckle to ensure that the microcrystalline fixing rod 11 will not easily fall off after it is inserted; when in use, the microcrystalline head 10 is fixed to the adjustment knob seat 9 by a detachable buckle.

[0033] In a further preferred embodiment of this utility model, a threaded hole is provided at the connection between the linkage rod 4, the first bearing 5, and the second bearing 6, and a fixing bolt is installed on the inner thread of the threaded hole.

[0034] Furthermore, the microcrystalline fixing rod 11 and the drive rod 7 are connected by a magnet 12, and the microcrystalline head 10 and the adjustment knob seat 9 are connected by a detachable snap-fit. These two parts are a kit for easy replacement by the user.

[0035] In a further preferred embodiment of the present invention, a threaded hole is provided on one side of the motor eccentric sleeve 3, and the motor eccentric sleeve 3 is connected to the first bearing 5.

[0036] Furthermore, the reciprocating motion of the drive rod 7 drives the microcrystalline fixing rod 11 to reciprocate, thereby achieving high-frequency contact between the microcrystalline head 10 on the microcrystalline fixing rod 11 and the face.

[0037] In a further preferred embodiment of this utility model, a limiting groove is provided above the adjustment knob seat 9, and the adjustment knob 8 and the adjustment knob seat 9 are connected.

[0038] Furthermore, the adjustment knob seat 9 has a groove, and a rib protrudes from the handle to restrict the direction and allow it to move axially. In use, the user can adjust the linear movement of the adjustment knob seat 9 on the handle housing by turning the adjustment knob 8.

[0039] In a further preferred embodiment of this utility model, the adjusting knob 8 is made of iron, and the outer side of the adjusting knob 8 is coated with Teflon.

[0040] Furthermore, the adjusting knob 8 is made of iron and coated with Teflon. As a guide sleeve, it greatly reduces the friction between the drive rod 7 and the adjusting knob 8 during reciprocating motion, thus increasing the lifespan of the mechanism. The linkage rod is curved, so the shape of the handle is not limited to the microchip and the other end of the linkage rod being aligned in a straight line.

[0041] The specific operation is as follows: when the motor body 1 starts, it drives the motor eccentric sleeve 3 to rotate around the motor body 1. One end of the linkage rod 4 is eccentrically connected to the motor eccentric sleeve 3. Therefore, the rotation of the linkage rod 4 drives the drive rod 7 to make linear reciprocating motion under the guidance of the adjustment knob seat 9. The reciprocating motion of the drive rod 7 drives the microcrystalline fixing rod 11 to make reciprocating motion, thereby achieving high-frequency contact between the microcrystalline head 10 on the microcrystalline fixing rod 11 and the face.

[0042] The microcrystalline fixing rod 11 passes through the microcrystalline head 10. The microcrystalline head 10 has a buckle to ensure that the microcrystalline fixing rod 11 will not easily fall off after it is inserted. When in use, the microcrystalline head 10 is fixed to the adjustment knob seat 9 by a detachable buckle. The adjustment knob seat 9 has a groove and a rib protruding on the handle to restrict the direction and allow it to move axially. When in use, the user can adjust the linear movement of the adjustment knob seat 9 on the handle shell by turning the adjustment knob 8. At this time, the user can adjust the distance between the end face of the microcrystalline head 10 and the microcrystalline chip on the microcrystalline fixing rod 11. This allows the user to adjust the actual travel of the microcrystalline chip and the microcrystalline head 10 on the handle during reciprocating motion according to the tightness of the user's skin.

[0043] The adjustment knob 8 is made of iron and coated with Teflon. As a guide sleeve, it greatly reduces the friction between the drive rod 7 and the adjustment knob 8 during reciprocating motion, thus increasing the lifespan of the mechanism. The linkage rod is curved, so the shape of the handle is not limited to the microchip being aligned with the other end of the linkage rod. The microchip fixing rod 11 is connected to the drive rod 7 by a magnet 12. The microchip head 10 and the adjustment knob seat 9 are connected by a detachable snap-fit. These two parts are a kit for easy replacement by the user.
