[0021] In order to make the above objects, features, and advantages of the present utility model more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0022] Figures 1 to 4 A rotating hydrodermabrasion instrument nozzle is provided. First, refer to Figure 1 , Figure 1 which shows the usage effect range diagram of a non-rotating hydrodermabrasion instrument nozzle. It is the usage effect range diagram of the hydrodermabrasion instrument without using the rotating hydrodermabrasion instrument nozzle provided by the present utility model.

[0023] As shown in the figure, it is the effect when a linear nozzle is in use. The inverted triangle represents the nozzle, the vertical straight line represents the liquid outlet pipe of the nozzle, and the dotted line part indicates the diffusion range of the water molecule beam ejected by the liquid outlet pipe. The water molecule beam ejected by the nozzle is linear, and the radius of its water molecule beam usually does not exceed the inner radius of the nozzle. Due to the action of air, as the water molecule beam moves away from the nozzle, the volume of the water molecule mist formed gradually spreads. However, because the inner radius of the nozzle is very small, the volume of the water molecule mist formed by such a nozzle is usually small. At this time, when acting on the skin at a short distance, the skin area usually affected by the water molecule mist is narrow and limited.

[0024] Based on this, the improvement of the present utility model for the nozzle is achieved by changing the setting of the thin tube in the nozzle to expand the radius of the water molecule beam. On the other hand, the inventor also found that it is usually difficult for the user of the hydrodermabrasion instrument to control the distance between the nozzle and the skin well during operation, that is, the action distance of the hydrodermabrasion instrument, and different action distances result in uneven beauty effects. Therefore, a stable action distance helps to evenly beautify the skin. So the designed nozzle needs to increase the action area while stabilizing this action area.

[0025] Refer to Figures 2 to 3, the rotating hydrodermabrasion instrument nozzle 1 provided by the present utility model specifically includes: a housing 10, a rotating mechanism 20, and a stabilizing mechanism 30. The housing 10 is a nozzle housing that wraps the core, and specifically includes a front handle body 11, a front handle body cover 12, and a nozzle sleeve 13. The core is the core part of the rotating hydrodermabrasion instrument nozzle 1 and is a component that provides a water molecule beam. The front handle body 11 is connected to the front handle body cover 12, and the front handle body cover 12 is connected to the nozzle sleeve 13. For ease of understanding, in this schematic diagram, the rotating hydrodermabrasion instrument nozzle 10 is set with the nozzle sleeve 13 at the lower end and the front handle body 11 at the upper end. As shown in the figure, on the housing space formed by the front handle body 11, the front handle body cover 12, and the nozzle sleeve 13, there is also a motor pressure plate shielding cover 14. The motor pressure plate shielding cover 14 is connected to the front handle body 11 and the front handle body cover 12 and covers the motor pressure plate 23 to form a part of the housing 10.

[0026] The nozzle sleeve 13 includes a nozzle sleeve main body 131 part and an extension part 132, and the extension part 132 extends out of the nozzle sleeve main body 131 part with a preset length. The preset length can be any length greater than 0, and the extension part can wrap the toothed rotating shaft type nozzle.

[0027] The housing 10 provides protection for the core of the rotating hydrodermabrasion instrument nozzle 1. In some examples, the material of the housing can be ABS, PC, PE, POM, PPO, PP, PVC, iron, aluminum, steel, synthetic metal, etc. And the materials of the front handle body 11, the front handle body cover 12, the nozzle sleeve 13, and the electrode pressure plate shielding cover 14 can be different.

[0028] The rotating mechanism 20 is the part that provides power for liquid output in the core of the rotating hydrodermabrasion instrument nozzle 1. The rotating mechanism includes a toothed motor 21, a toothed rotating shaft type nozzle 22, and a motor pressure plate 23. The toothed motor 21 includes a motor pressure plate main body 211 part and a first gear 212. The toothed rotating shaft type nozzle 22 includes a rotating shaft type nozzle main body 221 part and a second gear 222. Among them, the first gear 212 meshes with the second gear 222. The motor pressure plate 23 tightly presses the toothed motor 21 so that the toothed motor 21 is closely attached to the front handle body cover 12.

[0029] The function of the rotating mechanism 20 is to provide an atomized liquid small molecule beam with a relatively large radius in the cross section.

[0030] The stabilizing mechanism 30 includes a needle 31, a needle tube gasket 32, and a needle tube gasket pressing ring 33. The needle 31 is arranged on the central axis of the needle tube gasket 32 and is inserted into the bottom end of the needle tube gasket 32 while passing through the toothed rotating shaft type nozzle 22.

[0031] The needle tube gasket 32 includes a gasket main body 321 and a gasket front shell 322, and the needle 31 is arranged on the central axis of the gasket front shell 322.

[0032] Based on the design of the above-mentioned stable mechanism 30, the liquid bottle 40 is disposed in the space formed by the needle tube gasket 32. In an alternative embodiment, a movable sealing piston 41 is provided at the upper end of the liquid bottle 40. When the piston moves downward, it can squeeze the liquid to the liquid outlet part 202 and spray it in the form of a water molecule beam. Of course, the liquid bottle 40 may not be provided with a movable sealing piston, and the liquid is discharged to the liquid outlet part 202 through the pressure difference between the upper and lower ends of the needle 31.

[0033] When installing the liquid bottle 40 onto the needle tube gasket 32, the needle 31 on the needle tube gasket 32 is inserted into the bottle mouth of the liquid bottle 40, and at this time, the upper end of the needle 31 contacts the liquid in the liquid bottle 40.

[0034] In the case where the above structure is assembled into the rotating hydrodermabrasion instrument nozzle 1, the front handle body 11, the front handle body cover 12, the nozzle sleeve 13, the toothed rotating shaft type nozzle 22, the needle tube gasket 32, and the needle tube gasket pressing ring 33 are all concentric with the central axis.

[0035] In a preferred embodiment, the rotating hydrodermabrasion instrument nozzle further includes a first O-ring 51 and / or a second O-ring 52. The first O-ring 51 is located in the upper concave portion of the front handle body 11 and is concentric with the front handle body 11. At this time, the first O-ring 51 helps for a tight connection when the nozzle is connected to the hydrodermabrasion instrument. The second O-ring 52 connects the front handle body 11 and the toothed rotating shaft type nozzle 22 and is concentric with the front handle body 11. At this time, the second O-ring 52 helps for a tight connection between the front handle body 11 and the toothed rotating shaft type nozzle 22.

[0036] In a preferred embodiment, a bearing 224 is further provided on the outer periphery of the liquid outlet part 202 of the toothed rotating shaft type nozzle 22, and the bearing 224 is concentric with the toothed rotating shaft type nozzle 22. Preferably, a retaining ring 225 concentric with the bearing 224 is provided at the lower end of the bearing 224. The toothed rotating shaft type nozzle 22 includes a rotating shaft type nozzle main body 201 part and a liquid outlet part 202.

[0037] Among them, the liquid outlet part 202 is a pipe with a liquid outlet thin tube, including a liquid outlet pipe 2021 and a liquid outlet thin tube 2022. The liquid outlet thin tube 2022 is deflected at a preset angle, that is, the straight line where the liquid outlet pipe 2021 is located and the straight line where the liquid outlet thin tube 2022 is located form a preset angle. Preferably, the preset angle can be an angle greater than 0°. The preset angle can be 5°, 8°, 10°, 12°, etc. The rotating shaft type nozzle main body 201 is a flat conical shell and is connected to the liquid outlet part 202.

[0038] According to the rotating water-light instrument nozzle described above, when the motor is started, the first gear 212 rotates. Since the first gear 212 meshes with the second gear 222, the rotation of the first gear 212 drives the rotation of the second gear 222. The toothed rotating shaft type nozzle 22 where the second gear 222 is located is driven to start rotating, and further drives the rotation of the liquid outlet part 202.

[0039] Referring to Figure 4 , at this time, the toothed motor is in the starting state. As shown in the figure, it is the effect when the nozzle provided by this application is in use. The inverted triangle represents the nozzle, the vertical line represents the liquid outlet pipe of the nozzle, the solid and dashed lines indicate the space that the liquid outlet pipe can reach after rotation, and the dashed part indicates the diffusion range of the water molecule beam ejected by the liquid outlet pipe. Different from Figure 1 the situation, the water molecule beam ejected by the nozzle is linear. However, since the thin pipe of the liquid outlet part has a certain preset angle with the central axis (vertical direction), at this time, the rotation of the liquid outlet part drives the thin pipe to rotate around the central axis at the preset angle on the fulcrum P, and the water molecule beam sprays out from the thin pipe. At this time, the water molecule mist formed is a water molecule mist with a second radius, and the second radius is greater than the preset radius. With the adjustment of the preset angle, the size of the second radius also changes.

[0040] A rotating water-light instrument nozzle provided by the present utility model can increase the spraying area of the water molecule beam of the water-light instrument, thereby expanding the area acting on the skin and making the use of the water-light instrument more convenient; the nozzle head increases the extended distance on the basis of the existing ordinary nozzle, which can facilitate the user to stabilize the distance between the liquid outlet and the skin when using the water-light instrument. The stable acting distance helps to achieve a better beauty effect.
