Disclosed is a fingernail printing device, comprising a main frame (1) provided with an annular groove (11), an annular soft rubber ring (2) engraved with printing patterns (21), wherein the annular soft rubber ring (2) is embedded into the annular groove (11), the outer peripheral surface of the annular soft rubber ring (2) is provided with arch-shaped protrusions (22), with the printing patterns (21) being engraved on the arch-shaped protrusions (22); and further comprising an oil-scraping sheet (3) may be provided on the main frame (1). The present device is able to coat fingernails with patterns simply and quickly, and the device is safe enough so as to cause no damage to a user&#39;s skin during usage.
A: A portable, suction-type, anti-fogging myopia-correction eyewear, the eyewear comprising: a myopia-correction lens body (1) and a suction pad (2) constructed using soft silicone rubber. The myopia-correction lens body (1) and the suction pad (2) are formed using injection molding. The suction pad (2) is a hollow frustum with a narrower top. An upper portion of the suction pad (2) is formed into a circular surface (22). The upper portion of the suction pad (2) is provided with a circular groove (21). The myopia-correction lens body (1) comprises a lens portion (11) and a connecting portion (12). The lens portion (11) and the connecting portion (12) are formed as a single structure. The connecting portion (12) is a frustum-shaped structure with a narrower top. A top end of the connecting portion (12) is connected to the lens portion (11). The diameter of a bottom end of the connection portion (12) corresponds to the diameter of a top end of the suction pad (2). The bottom end of the connection portion (12) is provided with a circular snap-fit protrusion (121) corresponding to the ring-shaped groove (21). The circular snap-fit protrusion (121) forms a snap-fit connection by being inserted into the circular groove (21). The portable, suction-type, anti-fogging myopia-correction correction eyewear has a simple structure and good sealing and anti-fogging properties. The eyewear can be adhered multiple times over an extended period and is resistant against aging and deformation.
B: Disclosed are a device capable of manicuring a nail using a spray gun and a method for manicuring a nail using the manicure machine. The manicure machine (1) comprises a measuring module (2) capable of measuring a three-dimensional configuration of a finger (11)/nail; a print film module (7), wherein the print film module (7) comprises at least one print film execution module (73), the print film execution module (73) comprises a print film (710), and the print film execution module (73) can unwind/wind/move the print film (710); an engraving module (3) capable of engraving a pattern on the print film (710), wherein the print film module (7) can press the print film (710), on which the pattern is engraved, onto the finger (11); and a spraying and painting module (8) capable of coating the pattern of the print film (710) with a paint/nail polish by means of spraying and/or brushing, so as to print the pattern onto the nail. The manicure machine (1) can manicure the nail by using an airbrush and a brush without damaging the manicure pattern.
C: Disclosed are a drip irrigation pipe with an anti-blocking function and a machining method thereof. The drip irrigation pipe comprises: a water supply pipe (1), wherein the water supply pipe (1) is used for delivering irrigation water; a cylindrical dropping head (2), wherein the cylindrical dropping head (2) is provided with an annular groove (21), and a water outlet hole (22) penetrating the cylindrical dropping head (2) is provided in the annular groove (21); and an elastic sleeve (3), wherein the elastic sleeve (3) is arranged on the cylindrical dropping head (2) in a sheathed manner and is located in the annular groove (21), the elastic sleeve (3) covers the water outlet hole (22), the cylindrical dropping head (2) is arranged in the water supply pipe (1), a water outlet (11) matching the cylindrical dropping head (2) is provided in the water supply pipe (1), and the water outlet (11) is located outside the annular groove (21). The machining method comprises the step of, in the extrusion molding process of the water supply pipe (1), enabling the cylindrical dropping head (2) to be embedded in the extrusion-molded water supply pipe (1).
D: A waterproof ventilating sole (1) is provided. A plurality of grooves (2) are distributed on the upper surface of the sole (1). At least one through hole (3) leading to the bottom surface of the sole (1) is provided on the bottom of each of the grooves (2). A film button (5) is mounted in each of the grooves (2). The film button (5) comprises a ring corresponding to the grooves (2) and at least one waterproof ventilating film (7) tensioned on the ring. The film button (5) is provided with waterproof chamfers (6) which are the outward prolongation of the upper end of the film button (5). The bottom surface of the waterproof chamfers (6) is a plane or provided with at least a cycle of annular protrusion and/or annular concave groove. A configuration matched with the annular protrusion and/or ring concave groove is correspondingly provided on the upper surface of the sole (1).
