Detailed Description of the Embodiments

[0024] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0025] In the embodiments of the present invention, if there are directional indications (such as up, down, left, right, front, back...), they are only used to explain the relative positional relationship, movement conditions, etc. between components in a certain specific posture (as shown in the attached drawings). If this specific posture changes, the directional indications will also change accordingly.

[0026] In addition, in the present invention, the descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0027] Please refer to Figures 1 to 8 , the three-dimensional nail art printing device of the embodiments of the present invention includes a main body. The main body is filled with nail polish / paste. The nail polish / paste in the main body can be filled in a single color or in separate colors; due to the non-Newtonian fluid characteristics of the viscous liquid, when it is extruded and flows outwards, its flow is still layered and is ejected from the nozzle, so as to form a specific color / pattern accumulation on the nail.

[0028] The components of the nail polish / paste can be specifically selected according to the actual molding requirements. For example, the nail polish / paste includes the following components by mass percentage: Acrylate oligomer 30 - 40%; Photoinitiator TPO - L 3 - 5%; Nano - silica 5 - 8%; Pigment / magnetic particles 2 - 10%.

[0029] The viscosity of the nail polish / paste is 100 - 2200 cPs (thixotropic index > 2) to support rapid curing and three - dimensional molding.

[0030] A detachable nozzle is provided at the front end of the main body, and the nozzle is provided with a pattern hole of a preset shape (for example, a hole in the shape of a rose). Specifically, the nozzle can be connected to the main body by screwing or snap - fitting to achieve detachability, which is convenient for users to replace the nozzle with different shaped pattern holes. The nozzle adopts a three - dimensional nozzle module, which supports the molding of relief patterns with a height of 0.1 - 5 mm. Specifically, the nozzle can also adopt a split design, that is, the nozzle consists of a nozzle body and a replaceable pattern piece. The pattern piece is provided with a pattern hole of a preset shape. If the user needs to replace the pattern hole with a different shape, only the pattern piece needs to be replaced.

[0031] A quantitative extrusion mechanism and an ejection mechanism are provided on the main body. The quantitative extrusion mechanism facilitates the user to quantitatively extrude the nail polish / paste in the main body. The ejection mechanism is used to eject the quantitatively extruded nail polish / paste through the pattern hole of the nozzle. By releasing an instantaneous thrust through the ejection mechanism, the nail polish / paste forms a relief on the nail through the nozzle.

[0032] In embodiment 1, the main body is tubular or cylindrical, and preferably, the main body adopts a pen-shaped shell. In specific implementation, a nail polish tube containing nail polish / cream can also be directly arranged on the main body. After the nail polish / cream is used up, only the nail polish tube needs to be replaced separately, which is more convenient to use. The quantitative extrusion mechanism includes an upper piston rod correspondingly arranged at the end of the main body, and the ejection mechanism includes a lower piston rod and an ejection release member arranged in the main body. A plurality of positioning parts are arranged on the outer periphery of the lower piston rod, and one or more limiting parts corresponding to the positioning part are arranged on the inner wall of the main body, and the ejection release member is correspondingly arranged between the upper piston rod and the lower piston. The positioning part and the limiting part are convex rings or annular grooves, which can be selected according to the specific implementation.

[0033] As an implementation mode, the ejection release member is a spring (such as a coil spring, a leaf spring, an annular spring, a disc spring, etc.), a spring sheet (a rubber diaphragm may be used), a spring clip or a miniature gas spring, or is composed of two permanent magnets arranged opposite to each other (i.e., the ejection release is achieved by utilizing the principle that the same poles of two permanent magnets repel each other). In specific implementation, if the ejection release member is a spring clip, a plurality of spring clips may be used to connect the upper piston rod and the lower piston rod. Preferably, the positioning portion on the outer periphery of the lower piston rod and the limiting portion on the inner wall of the body are staggered equidistantly up and down. For example, the spacing is 2.5 mm, and the tolerance is ±0.05 mm, so that the single extrusion volume is 0.03±0.01 mL.

[0034] When the user presses the upper piston rod, the positioning part on the lower piston rod contacts the limiting part, the ejection release part is compressed, the user continues to press the upper piston rod, the positioning part on the lower piston rod presses over the limiting part, the ejection release part recovers quickly, and the lower piston rod continues to press down (the upper piston rod is pressed by the user's finger), and the lower piston rod is pressed down to the next limiting part, during which the nail polish / cream is quickly squeezed out, and the nail polish / cream forms a preset three-dimensional pattern on the nail through the nozzle. Due to the elastic force, the nail polish / cream is not easy to produce continuous drawing, and it is easy to form a three-dimensional shape. The multiple equidistant positioning parts on the piston rod make the volume of the nail polish / cream shot out each time the same.

[0035] In embodiment 2, a curing mechanism for curing nail polish / cream is provided at the end of the upper piston rod. The curing mechanism facilitates the user to cure the nail polish / cream on the nails to form a preset three-dimensional pattern. Preferably, the curing mechanism is one or more of a UV lamp curing component, an LED lamp curing component, a UV and LED lamp mixed curing component, and a ceramic heating plate curing component. The UV lamp curing component can use a dual-wavelength (365 / 405nm) UV lamp curing component.

[0036] As an embodiment, the nail polish / cream is a single-color nail polish / cream, or a multi-color nail polish / cream with a multi-layer structure. The multi-color nail polish / cream is filled in the body and mixed in an orderly manner to achieve a color pattern at one time during extrusion and complete the color distribution at one time.

[0037] As an implementation manner, a pressing portion is provided at the end of the upper piston rod. The diameter of the pressing portion is larger than that of the upper piston rod, which facilitates the user to press the upper piston rod. The pressing portion can also adopt a soft pressing pad, which can make the user more comfortable when pressing.

[0038] As an implementation manner, an outer cover corresponding to the pattern hole is provided at the front end of the nozzle. The outer cover covers outside the pattern hole. The height of the outer cover is greater than the height of the three-dimensional pattern expected in the injection design. When in use, the nozzle can be placed on the nail, and the outer cover covers the nail, and then the pattern can be directly injected. The outer cover is beneficial to reducing the wire drawing of the nail polish / paste and facilitating the positioning of the pattern on the nail.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalent scope.
