Mosquito-repellent patch

Abstract

The invention relates to a mosquito-repellent patch. The mosquito-repellent patch comprises a substrate made from a flexible material, an adhesive layer is arranged on the bottom face of the substrate, and a capsulation film is arranged on the bottom of the adhesive layer. A mosquito-repellent layer is arranged on the top face of the substrate, and the mosquito-repellent layer is filled with mosquito-repellent drugs; thermal-expansion protrusions are arranged on the portion, between the substrate and the mosquito-repellent layer, attached to the top face of the substrate, and as the temperature is higher, more largely the thermal-expansion protrusions expand. The outer surface of the mosquito-repellent layer is wrapped with a sealing layer, normally-closed air holes are formed in the sealing layer, and the opening positions of the normally-closed air holes directly face the positions of the thermal-expansion protrusions and are matched with the positions of the thermal-expansion protrusions; only when the thermal-expansion protrusions expand, the normally-closed air holes are jacked up and opened. The mosquito-repellent patch is novel in structure, unique in principle, high in sealing performance and convenient to package and store; the mosquito-repellent patch can pause in the midway and continues to be used, and the using duration is effectively ensured. The structure can better fit the skin, and the using experience is more comfortable.

[0002] In the hot summer, mosquitoes are rampant, and various mosquito repellent products emerge in endlessly; among them, mosquito repellent stickers are loved by users for their advantages of small size, convenient use, safety and harmlessness; mosquito repellent stickers are a kind of products that can be attached to clothing, A patch on the skin, one side of the mosquito repellent patch is attached with adhesive, and the other side contains a mosquito repellent sheet. The mosquito repellent sheet slowly and continuously volatilizes the mosquito repellent smell, thereby protecting the user from mosquito bites; because the mosquito repellent patch is easy to volatilize , if the airtightness of the packaging is not good, it is easy to fail early, so the packaging and storage of the mosquito repellent stickers are more troublesome; the mosquito repellent effect may be insufficient in actual use; Uncomfortable, if the stickiness is too weak, it will fall off easily; therefore, there are minor problems such as shortened use time and easy fall off during use; in addition, sometimes children may only go out for half an hour, and the mosquito repellent patch cannot be used halfway after opening Pause, at this time a mosquito repellent patch will be wasted, resulting in a certain waste of resources
