[0055] Embodiment 2:
[0056] As shown in Figure 2A A gel patch includes a sheet-shaped gel body 1 having an upper surface 11, a side surface 12 and a lower surface 13, the upper surface 11 of the gel body is provided with a plurality of fluffs 14, and the outer surface 141 of the fluff is connected with the upper surface 11 of the gel body; as shown in Figure 2B A housing capable of containing and / or forming the above-mentioned gel patch is shown, the housing 2 has a housing inner surface 21 and a housing outer surface 22, at least part of the housing inner surface 21 surrounds a housing inner cavity 20, the housing inner cavity 20 can contain the gel body 1, the housing inner cavity 20 has a plurality of containing cavities 200 corresponding to the fluffs 14 of the gel patch and capable of containing the fluffs 14, the containing cavities 200 are recessed from the housing inner surface 21 to the housing outer surface 22, further comprising a through hole 201 penetrating the containing cavity inner surface 202 and the housing outer surface 22, the containing cavities 200 are in communication with the external environment through the through hole 201, and the through hole 201 is located at the bottom of the containing cavities 200.
[0057] Figure 2C 、 2DThe gel body 1 of the gel patch is placed in the shell cavity 20 of the shell 2, and the shell cavity 20 is completely filled with the gel body 1. At this time, the hairs 14 of the gel patch are respectively located in the accommodating cavity 200, and the outer surface 141 of the hairs are in contact with the inner surface 202 of the accommodating cavity. The top 142 of the hairs is close to the through hole 201, and the lower surface 13 of the gel patch is flush with or slightly lower than the edge 211 of the shell. At this time, the shell 2 with the accommodating cavity 200 can not only be used as a container for storing the gel body 1 of the gel patch, but also as a mold for forming the gel body 1 of the gel patch. When used as a container, the hairs 14 are respectively placed in the accommodating cavity 200. During transportation or long-term storage, During the molding process, the shape of the villi 14 will not be affected, such as the villi will not be bent or kinked; when used as a mold, the raw materials for making the gel patch can be directly injected into the inner cavity of the shell. When the gel raw materials enter the accommodating cavity 200, the gas trapped in the accommodating cavity is discharged through the through hole 201, thereby avoiding the situation where the villi are defective due to poor exhaust during the molding process of the gel body, that is, the through hole 201 assists in molding the villi with a relatively complete shape; the shell 2 with the accommodating and molding functions can be molded with medical-grade materials such as polypropylene. During production, the flowing gel is poured into the inner cavity 20 of the shell and can be molded after cooling, thereby reducing production costs and improving production efficiency; Figure 2E The outer surface 22 of the shell 2 is shown, and a plurality of through holes 201 corresponding to the fluff are distributed on the outer surface 22 of the shell.
[0058] Example 3:
[0059] like Figures 3A-3E As shown, the upper surface 11 of the gel body 1 of the gel patch is provided with a plurality of sea anemone tentacle-like hairs 14, and the outer surface 141 of the hairs is connected to the upper surface 11 of the gel body; the gel body 1 is also provided with a weak connection area 15 that is easy to tear, and the gel body 1 between the weak connection areas 15 is in a disconnected state 16. The weak connection areas 15 are arranged circumferentially with the gel bodies 1 in the disconnected state 16, and the weak connection areas 15 are located in the gaps between the hairs 14; Figure 3A The gel body 1 of the gel patch is shown attached to the forehead of a human face; Figure 3B The complete gel patch is shown, with the weak connection area 15 and the gel body 1 in the disconnected state 16 arranged circumferentially and forming a blank area on the gel body 1; Figure 3C The diagram shows that part of the gel body 1 at the weak connection area 15 has been torn, forming a cross section 151. This means that the circumferentially arranged weak connection areas 15 between the hairs 14 can now be completely torn apart, leaving only a smaller area of the gel body 1 in the middle area to be attached to human skin, such as the skin surface of a child's forehead. Figure 3D A schematic cross-sectional view of the gel body 1 is shown, illustrating the specific structure of the weak connection region 15 , namely, the weak connection region 15 is where the upper surface 11 and / or the lower surface 13 of the gel body are concave toward the center but are not disconnected. In this figure, both the upper surface and the lower surface are concave toward the center;Figure 3E A cross-sectional view of the gel body 1 is shown, showing that the gel body at the weak connection area 15 has been completely broken to form a cross section 151 , and the central gel body 1 and the peripheral gel body 1 are separated.
[0060] like Figure 3F As shown, the gel body 1 of the gel patch has not yet been placed in the shell cavity 20 of the shell 2, and the support body 23 of the shell cavity 20 corresponds to the gel body 1 in the disconnected state 16, that is, when the gel body 1 is placed in the shell cavity 20, the support body 23 respectively penetrates into the disconnected state 16 and adheres to the gel body there, preventing the gel body 1 from shaking in the shell cavity 20, thereby avoiding damage to the morphology of the villi 14 on the gel patch.

The first molding body 24 and the second molding body 25 are located in the gap of the accommodating cavity 200 and are arranged at intervals around the circumference. When molding the gel body, the flowing gel raw material is poured into the shell cavity 20 until the gel raw material is flush with the shell edge 211 or slightly lower than the shell edge 211. At this time, due to the small opening of the through hole 201 at the bottom of the accommodating cavity 200, the gel raw material cannot flow out of the through hole 201, but the gas can be discharged from the through hole 201. After cooling for a period of time, a complete gel patch is formed. Figure 3H As shown, the shell 2 is used as a container for storing the gel patch. The gel body 1 of the gel patch has not yet been placed into the shell cavity 20. When placed, the villi 14 on the gel body 1 must correspond one-to-one with the accommodating cavity 200, the weak connection area 15 of the gel body must correspond to the first molded body 24 of the shell cavity 20, and the gel body 1 in the disconnected state 16 must correspond to the second molded body 25.

The hairs 14 extend upward from the upper surface 11 of the gel body, and the outer surface 141 of the hairs is connected to the upper surface 11 of the gel body. The figure shows that the hairs 14 on the upper surface 11 of the gel body 1 extend to different heights. The height of the hairs 14a in the central area of the gel body 1 is lower than the height of the hairs 14b in the peripheral area of the gel body 1, that is, the vertical distance from the top 142a of the hairs in the central area to the upper surface 11 of the gel body is lower than the vertical distance from the top 142b of the hairs in the peripheral area to the upper surface 11 of the gel body; as shown in FIG. Figure 4BAs shown, in order to increase the effective heat dissipation area of the gel body 1 and improve the cooling and antipyretic effect, the side surface 12 of the gel body 1 is provided with fluff 14, and the fluff 14 extends outward from the side surface 12 of the gel body; Figure 4C As shown, in order to increase the effective heat dissipation area of the gel body 1 and enhance the uniqueness of the gel patch, a portion of the side surface 12 of the gel body 1 extends outward to form an arc area 121 and is recessed inward to form a concave area 122. The side surface 12 of the gel body in the arc area 121 and the concave area 122 are both provided with a plurality of hairs 14.
