DETAILED DESCRIPTION

[0018] In order to more clearly illustrate the purpose, technical solutions and advantages of the embodiments of the present invention, the present invention will be further described in conjunction with the accompanying drawings and embodiments below for a clear and complete description. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention. In addition, the directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "inside", "outside", etc., are only referenced to the directions of the attached diagrams. The directional terms used are for better and clearer explanation and understanding of the present invention, rather than indicating or implying the orientation that the present invention must have, and therefore cannot be understood as limitations on the present invention.

[0019] Embodiments of the present invention Figures 1 to 5As shown in the figure, an ice skin beauty instrument includes a cylindrical shell 1, which means that the shell 1 is connected from top to bottom. It can adopt a metal shell or a plastic shell that can withstand temperature changes, or a combination of the two, such as ABS plastic, aluminum alloy material. The diameter of the upper end of the shell 1 is smaller than the diameter of the lower end. The upper part of the shell 1 is equipped with an upper barrel body 2 with an opening facing upward for filling heat-insulating material. The upper barrel body 2 is installed in the upper part of the shell 1 through the opening at the upper end of the shell 1, and then the heat-insulating material is filled in the upper barrel body 2, and the heat-insulating material will not fall from the upper barrel body 2. At this time, the heat-insulating material can be water-absorbing beads made of water-absorbing resin, or ice stones, etc. When ice compress is needed, they are placed in a refrigerator to freeze or refrigerate for a certain period of time before use. time, such as 30 minutes, and then fill it into the upper barrel body 2, or first fill the upper barrel body 2 with insulation material, and then put the upper barrel body 2 and the insulation material into the refrigerator for refrigeration or freezing for a certain period of time, and then take out the upper barrel body 2 and install it in the shell 1. Refrigeration or freezing is carried out according to different needs. When hot compress is needed, it can be placed in hot water or other heat sources for heating. The lower part of the shell 1 is equipped with a lower barrel body 3 with an opening downward for filling insulation material. The lower barrel body 3 is installed and used in the same principle as the upper barrel body 2, and can also be prepared with the same material as the shell. The bottom of the upper barrel body 2 and the bottom of the lower barrel body 3 are arranged relative to each other and there is a gap between the two, that is, in the shell 1, the upper barrel body 2 is placed upright. The lower barrel body 3 is inverted, and the gap between the two prevents the upper and lower barrel bodies from contacting each other, thereby ensuring the cold compress effect of their corresponding ends. The flow of air can be used to keep the heat exchange speed in a stable state, avoiding the accumulation of insulation materials to the bottom under the action of gravity during holding, thereby causing local overcooling, thereby achieving uniform and effective ice compress and better beauty effect. A metal upper cover 4 that is matched and sleeved on the outside of the upper barrel body 2 is matched and installed in the upper end port of the shell 1, and a metal lower cover 5 that is matched and sleeved on the outside of the lower barrel body 3 is matched and installed in the lower end port of the shell 1. The metal upper cover 4 is matched and installed in the port at the upper end of the shell 1, which means that the size of the metal upper cover 4 matches the size of the upper end port of the shell 1. Similarly, the size of the metal lower cover 5 matches the size of the lower end port of the shell 1. Since the caliber of the upper end of the shell 1 is smaller than that of the lower end, the metal upper cover 4 is smaller than the metal lower cover 5. When they are installed on the shell 1, two ice compress areas with different surface areas are formed. The area corresponding to the upper end is small, and the area corresponding to the lower end is large. When the metal upper cover 4 and the metal lower cover 5 are installed on the shell 1, they are correspondingly sleeved on the outer walls of the upper barrel body 2 and the lower barrel body 3 to close the barrel body. At this time, the positions where they are connected to each other are, from the outside to the inside, the upper end of the shell 1 or the lower end of the shell 1, the metal upper cover 4 or the metal lower cover 5, the upper barrel body 2 or the lower barrel body 3. The installation of the metal upper and lower covers in the shell 1 can be achieved by a snap-fit ​​structure or a threaded connection.The matching sleeves of the upper and lower metal covers corresponding to the upper and lower barrel bodies mean that the upper and lower metal covers are both extended with annular side walls, and the inner walls of the annular side walls are tightly attached to the outer walls of the upper and lower barrel bodies. The two can be fixed by screws, that is, the upper and lower barrel bodies are fixed in the shell 1 to avoid shaking in the shell 1 during use. When in use, the thermal insulation material filled in the upper and lower barrel bodies is in contact with the metal upper cover 4 or the metal lower cover 5 correspondingly, and the metal upper and lower covers form a hot and cold conduction medium. At this time, the top of the metal upper cover 4 and the bottom of the metal lower cover 5 are both smooth planes. The smooth surface will not be conducive to the conduction of heat during the ice or hot compress process, will not cause damage to the skin, and is also conducive to its movement on the skin. Different sizes of metal upper covers 4 and metal lower covers 5 are used to achieve ice compresses on damaged skin of different areas to meet different usage requirements. When in use, hold the middle part of the shell 1 with your hand, and then select the metal upper cover 4 or the metal lower cover 5 to press on the corresponding skin according to the size of the area to be iced or hot-compressed. The whole structure is simple, easy to manufacture, can meet different usage requirements, and does not require wire power supply, so it is easy to carry and more conducive to use.

[0020] Further improvements such as Figure 1 , Figure 2 and Figure 5 As shown in , the housing 1 is provided with air holes 6. The provision of the air holes 6 enables the air in the housing to circulate with the outside air, thereby ensuring that the pressure inside and outside the housing 1 is the same and avoiding damage caused by thermal expansion and contraction.

[0021] Further improvements such as Figure 3 As shown in , the inner wall of the shell 1 is recessed radially outward with an upper step 10 at a position adjacent to the upper end of the shell 1, and the outer wall of the upper barrel body 2 is extended radially outward with an upper barrel body step 20 at a position adjacent to the barrel mouth, and the bottom surface of the upper barrel body step 20 presses against the top of the upper step 10. During use, it is only necessary to insert the upper barrel body 2 from the upper end of the shell 1. After insertion, the upper barrel body step 20 and the upper step 10 press against each other to form a limiting structure, so that the upper barrel body 2 will not fall downward in the shell 1. The position of the upper barrel body 2 is limited, and the upper barrel body 2 can be easily installed in the shell 1, and then a metal upper cover 4 is mounted on the upper barrel body 2, and the metal upper cover 4 is connected and fixed to the shell 1, thereby fixing the upper barrel body 2. Similarly, Figure 4 As shown in the figure, the inner wall of the shell 1 is recessed radially outward with a lower step 11 at a position adjacent to the lower end of the shell 1, and the outer wall of the lower barrel body 3 is extended radially outward with a lower barrel body step 30 at a position adjacent to the barrel mouth, and the top of the lower barrel body step 30 is pressed against the bottom surface of the lower step 11. During installation, it is only necessary to turn the shell 1 over, and then install the lower barrel body 3 and the metal lower cover 5 in the same installation manner.

[0022] Further improvements, such as Figure 1 As shown in , the outer wall of the upper barrel body 2 is provided with an upper barrel body trapezoidal card slot 21 extending from the open end of the upper barrel body 2 to the bottom end of the upper barrel body 2 along the axial direction of the upper barrel body 2. The card slot buffers the stress generated when the upper barrel body 2 is deformed during thermal expansion and contraction, avoiding the rupture of the barrel body. At the same time, the space in the card slot is also convenient for the flow of air therein, which is conducive to the transfer of heat. The card slot can be symmetrically arranged with two or more of them on the outer wall of the upper barrel body 2 with the axis of the upper barrel body 2 as the axis of symmetry. The card slot is formed by the radial inward depression of the side wall of the upper barrel body 2 along the upper barrel body 2, and the depressed part protrudes from the barrel of the upper barrel body 2, which enhances its strength and can also play a certain dispersion role on the heat preservation material filled in the upper barrel body 2, avoiding their accumulation, and more conducive to the transfer of heat. Similarly, the outer wall of the lower barrel body 3 is provided with a lower barrel body trapezoidal card slot 31 extending from the open end of the lower barrel body 3 to the bottom end of the lower barrel body 3 along the axial direction of the lower barrel body 3.

[0023] Further improvements, such as Figures 1 to 3 As shown in the figure, the shell 1 is a cylindrical body with a truncated cone-shaped side wall, which means that the diameter of the shell 1 gradually decreases from top to bottom, which is convenient for holding it during use. The outer wall of the shell 1 is provided with a plurality of spiral protrusions 12 at intervals along the circumferential direction, which increases the friction between the hand and the shell, prevents it from falling during use, and also increases the beauty of the product.

[0024] Further improvements, such as Figure 2 As shown in the figure, gaps 13 are provided between the upper barrel body 2 and the lower barrel body 3 and the inner wall of the shell 1, and there is no direct contact between the upper and lower barrel bodies and the inner wall of the shell 1, thereby avoiding drastic temperature changes. The air in the gap 13 is used to conduct heat, thereby maintaining a uniform speed of heat conduction and achieving a better ice compress effect.

[0025] As a further improvement, sealing rings are provided between the metal upper cover 4 and the metal lower cover 5 and the shell 1. The provision of the sealing rings allows the air inside the shell 1 to be cooled during use, and the moisture in the air condenses into liquid water, thereby preventing the liquid water from flowing out of the shell 1.

[0026] A method for preparing an ice skin beauty instrument, the steps of preparing the ice skin beauty instrument as described in any of the preceding items are as follows:

[0027] S1, preparation of the metal upper cover and the metal lower cover, cutting the aluminum alloy plate into aluminum strips and placing them in a steel mold for stamping, and then performing oxidation treatment on the surface to form the metal upper cover and the metal lower cover. When making the metal upper cover, the aluminum strips cut are adapted to the size of the metal upper cover, and then stamping is performed in the mold corresponding to the metal upper cover. Similarly, when making the metal lower cover, the aluminum strips cut are adapted to the size of the metal lower cover, and then stamping is performed in the mold corresponding to the metal lower cover. The stamped product is then oxidized to enhance its corrosion resistance and wear resistance. Before the oxidation treatment, the product can also be placed in a mixed acid solution of nitric acid and hydrofluoric acid for corrosion activation. The mixed acid contains 4-6% by weight of hydrofluoric acid. After activation, impurities in the aluminum alloy can be removed, and the quality of the oxide film on the surface of the aluminum alloy after oxidation treatment can be improved;

[0028] S2, preparation of the shell and the upper barrel and the lower barrel, adding the plastic raw material into the steel mold of the injection molding machine for injection molding, the molding temperature is 200-240 degrees, and the plastic raw material is baked at a temperature of 80-90 degrees for 2-2.5 hours before adding to the injection molding machine, and the pre-baking facilitates the subsequent molding process. In the subsequent molding process, the temperature inside and outside the raw material can be quickly consistent, saving energy, and the raw material can be mixed more evenly in the mold, thereby improving the quality of the product;

[0029] S3, assembly, soak the insulation material in clean water for 8-15 minutes, then pick it up and put it into the upper barrel and the lower barrel. When the insulation material absorbs water beads, the soaking will achieve the purpose of absorbing water. The ice stone can remove impurities and dirt on its surface on the one hand, and absorb moisture in it on the other hand. After the upper and lower barrels are filled with corresponding insulation materials, a metal upper cover is installed on the upper barrel and then placed in the upper part of the shell, and the metal upper cover and the shell are connected and fixed. At this time, the metal upper cover and the upper barrel can be connected and fixed with screws, and glue is applied to the edge of the metal upper cover and the metal upper cover and the shell are connected and fixed. A metal lower cover is installed on the lower barrel and then placed in the lower part of the shell, and the metal lower cover and the shell are connected and fixed. Similarly, the metal lower cover and the lower barrel can be connected and fixed with screws, and glue is applied to the edge of the metal lower cover and the metal lower cover and the shell are connected and fixed.
