Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, in particular to a damping device for a skin treatment instrument. BACKGROUND

[0002] The radio frequency skin treatment instrument is an instrument for skin treatment, which uses low-frequency electromagnetic waves to act on human pathological tissues, so that the polar water molecules in the tissues move at high speed to generate heat (i.e. endogenous heat effect), coagulate proteins at low temperature to lose activity, and finally fall off through the body's rejection, so as to achieve the treatment purpose. The radio frequency produces radio frequency waves at a specific depth under the skin, which act on the water molecules in the collagen, and the bipolar water molecules vibrate and rotate at high speed to generate heat by friction, thereby achieving the effect of heating the dermal collagen.

[0003] Since the radio frequency skin treatment instrument needs a high-frequency generator during use, the current passing through the transformer or coil generates electromagnetic vibration (magnetostriction effect) during the operation of the high-frequency generator.

DETAILED DESCRIPTION

[0020] The following examples are for illustrative purposes only and are not intended to limit the scope of the present application.

[0021] REFERENCE Figures 1-10A shock-absorbing device for a skin treatment instrument includes a movable base 1 with a rectangular lifting port 2. An instrument case 3 is fixedly connected to the upper end of the movable base 1 and outside the lifting port 2. The treatment instrument body 4 is mounted on the upper end of the instrument case 3. A load-bearing base plate 5 is located inside the lifting port 2. A movable box 6 is fixedly connected to the upper end of the load-bearing base plate 5. A high-frequency generator is fixedly installed inside the movable box 6. The high-frequency generator is existing technology and is connected to the treatment instrument body 4 via wiring, which will not be described in detail here. Slide grooves 9 are provided at both the front and rear ends of the movable box 6. The slide grooves 9 have a T-shaped cross-section when viewed from above. Movable grooves 10 are provided at both the front and rear ends of the movable box 6, communicating with the lower end of the corresponding slide grooves 9. The movable grooves 10 are isosceles trapezoids, and their width is greater than that of the slide grooves 9. The instrument box 3 has sliding openings 12 on both the front and rear walls, corresponding to the positions of the sliding grooves 9. The instrument box 3 is equipped with a lifting mechanism, which can drive the movable box 6 to move up and down through the sliding openings 12, so that the movable box 6 can be placed on the ground. The lower end of the load-bearing base plate 5 is fixedly connected to a rubber base 7. Under the weight of the load-bearing base plate 5 and the movable box 6, the rubber base 7 can effectively contact the ground, thus placing it stably on the ground and breaking its rigid contact with the movable seat 1, the instrument box 3 and the treatment instrument body 4. Then, when the high-frequency generator is working, the vibration force it generates can be absorbed by the rubber base 7, and will not affect the circuit board and precision instruments inside the treatment instrument body 4.

[0022] Ventilation openings are provided at both ends of the mobile box 6. A cooling fan 8 is fixedly installed in the ventilation opening at the left end. A heat dissipation vent is provided at the left end of the instrument box 3. The cooling fan 8 and the heat dissipation vent can effectively dissipate heat from the high-frequency generator and the treatment instrument body 4 during operation. Moreover, the mechanical vibration generated during the heat dissipation process will not affect the treatment instrument body 4.

[0023] The lifting mechanism includes two spring telescopic rods 11 that pass through and slide through corresponding sliding openings 12. One end of the spring telescopic rod 11 inside the instrument case 3 extends into the corresponding sliding groove 9 and is fixedly connected to a sliding plate. The sliding plate is slidably connected to the sliding groove 9. The two elastic telescopic rods 11 serve to support the moving box 6. The ends of the two spring telescopic rods 11 outside the instrument case 3 are fixedly connected to a horizontal plate 13. The right ends of the two horizontal plates 13 extend to the right side of the instrument case 3 and are fixedly connected to a lifting plate 14. The right end of the instrument case 3 is fixedly connected to a mounting plate 15 located above the lifting plate 14. A threaded rod 16 is rotatably connected between the mounting plate 15 and the moving seat 1. The threaded rod 16 passes through the lifting plate 14 and is threadedly connected to it. A drive motor 17 that drives the threaded rod 16 to rotate is fixedly installed on the mounting plate 15. Two sliding rods 18 are fixedly connected between the mounting plate 15 and the moving seat 1. Both sliding rods 18 pass through the lifting plate 14 and are slidably connected to it. The sliding rods 18 serve as limiters to ensure the stable lifting of the lifting plate 14.

[0024] Specifically, when the therapeutic instrument body 4 is to be used, the driving motor 17 needs to be started first, the threaded rod 16 is driven to rotate by the driving motor 17, thereby driving the lifting plate 14 and the two cross plates 13 to move downward, in the process of moving downward, the moving box 6 is kept in a suspended state supported by the two elastic extension rods 11, and the elastic extension rods 11 cannot be separated from the sliding groove 9 under the limiting action of the sliding groove 9 and the sliding plate, so that the moving box 6 can be stably moved to the ground. When the moving box 6 is moved to the ground, the lifting plate 14 and the two cross plates 13 can continue to move downward, so that the elastic extension rods 11 and the sliding plate continue to move along the sliding groove 9 until they are moved into the movable slot 10. In the movable slot 10, the sliding plate has sufficient left and right movement space, and cooperates with the extension and retraction of the elastic extension rods 11, so that each direction of vibration of the high-frequency generator in the moving box 6 has an effective movement space, and the influence on the moving seat 1 and the instrument box 3 is minimized. Similarly, the moving box 6 can be moved upward into the instrument box 3 by using the driving motor 17, which facilitates subsequent movement of the device (the vibration generated by the driving motor 17 is smaller than that of the high-frequency generator, and only works before and after the skin therapeutic instrument is used, so it will not cause substantial influence on the therapeutic instrument body 4).

[0025] The sponge frame 19 is fixedly connected to the inner wall of the lifting opening 2, and the sponge frame 19 is arranged in close contact with the outer wall of the moving box 6. The sponge frame 19 can ensure the stability of the moving box 6 and avoid shaking during movement, and has the effect of reducing shock and noise during movement. The inner walls of the instrument box 3 and the moving box 6 are attached with noise-reducing sponges, which are used to absorb the noise generated by the vibration of the high-frequency generator and reduce the noise influence of the device.

[0026] Through the shock-absorbing device, the main vibration source can be effectively separated from the instrument body before the skin therapeutic instrument is used, so that the vibration source is in contact with the ground alone, thereby minimizing the influence of vibration on the instrument body.

[0029] The two damping wheel assemblies on the left side are provided with a brake mechanism, the brake mechanism comprises an arc-shaped brake block 29 arranged above the wheel body 24, the wheel body 24 is made of antiskid rubber material, and the brake block 29 can effectively brake after being attached to the wheel body 24. The upper end of the brake block 29 is fixedly connected with two vertical rods 30, the upper ends of the two vertical rods 30 penetrate the inner top wall of the wheel frame 23 and are slidably connected therewith, the upper ends of the two vertical rods 30 are fixedly connected with a pressing plate 31, the pressing plate 31 is fixedly connected with the second spring 32 between the upper end of the wheel frame 23, the second spring 32 plays a supporting and resetting role, when the pressing plate 31 is pressed, the second spring 32 can be compressed, and the brake block 29 is attached to the wheel body 24 to realize braking, and after the pressing plate 31 is stopped pressing, the brake block 29 can be reset by using the elastic force of the second spring 32 to move upward, so as to release the brake.

[0030] The upper ends of the four movable shafts 22 are fixedly connected with end blocks, the upper ends of the corresponding two end blocks on the left and right sides are fixedly connected with a light rod 28, the upper end of each light rod 28 is provided with a limiting clamp block 33 corresponding thereto, the lower end of the limiting clamp block 33 is provided with a limiting opening, the width of the limiting opening is the same as the diameter of the light rod 28, the limiting clamp block 33 is fixedly connected with the corresponding horizontal plate 13 through a connecting rod, when the lifting mechanism moves the lifting box 6, the four limiting clamp blocks 33 are also moved downward, and then only the four light rods 28 need to be located below the four limiting clamp blocks 33, the four light rods 28 can be clamped by the four limiting clamp blocks 33, so as to lock the movable shafts 22 of the four universal wheels (when the universal wheels normally move, the four wheel bodies 24 are directed to the same direction, and then only the device needs to be moved to the left and be static, so as to ensure that the four light rods 28 are located below the four limiting clamp blocks 33).

[0031] When the movable shaft of the four universal wheels is locked, the device can only move laterally through the wheel bodies 24, and if the two wheel bodies 24 on the left are braked, the device can be locked in position.

[0032] The upper end of the moving seat 1 is provided with a groove 34 below the corresponding position of the four limiting clamping blocks 33, and the two grooves 34 on the left are both slidingly connected with a flat plate 35, the third spring 36 is fixedly connected between the flat plate 35 and the bottom wall of the groove 34, the lower end of the flat plate 35 is fixedly connected with a pressing block 37, the lower end of the pressing block 37 penetrates through the bottom wall of the groove 34 and is slidingly connected therewith, and the lower end of the pressing block 37 corresponds in position to the pressing plate 31.
