a thermal expansion bulge is arranged between the substrate and the mosquito repellent layer and is tightly attached to the top surface of the substrate, and the volume expansion of the thermal expansion bulge is larger when the temperature is higher; the outer surface of the mosquito repelling layer is coated with a sealing layer, the sealing layer is provided with a normally closed vent hole, and the opening position of the normally closed vent hole is in right-to-right matching with the position of the thermal expansion bulge; the normally closed vent is lifted open only when the thermal expansion lobe expands.

The invention has the beneficial effects that: the mosquito repellent patch is packaged in the packaging sleeve and is placed in a shade place; at the moment, the temperature is lower, the volume of the thermal expansion bulge in the contraction state is smaller, the normally closed vent hole is in the closing state, and the mosquito repellent layer is sealed between the sealing layer and the substrate, so that the mosquito repellent can be effectively prevented from volatilizing;

when the mosquito repellent patch is used, the adhesive layer is attached to the skin or the surface of clothes, and the temperature of the mosquito repellent patch is gradually increased due to the fact that the mosquito repellent patch is close to the skin of a human body, so that the thermal expansion bulges are gradually expanded, and the volume of the mosquito repellent patch is enlarged; with the increase of the volume of the thermal expansion bulge, the mosquito repelling layer is jacked up to form a bulge, and the normally closed vent hole is jacked open; the mosquito repellent medicine volatilizes from the normally closed vent hole, thereby generating the mosquito repellent effect; if the user returns to the room after short-term use, the mosquito repellent patch is taken down and put back into the packaging box; with the mosquito repelling patch separated from the skin of a human body, the temperature of the heat swelling bulge is rapidly reduced, the volume is reduced, the mosquito repelling layer does not swell, and the normally closed vent hole is restored to a closed state.

In conclusion, the mosquito repellent patch has strong sealing property when not used, and can effectively avoid ineffective volatilization of the drugs, thereby prolonging the service life of the mosquito repellent patch; simultaneously, this structure has the function of pause, continuation of using, and when the user went out for a short time and came back, the medicine can be blockaded by oneself, avoids lasting volatilizing to improve the utilization ratio of mosquito repellent subsides, effectively reduced the wasting of resources.

Preferably, the substrate is provided with a flow guide hole which is matched and right opposite to the thermal expansion bulge; the thermal expansion bulge is made of porous material, and a sealing film for covering the surface of the thermal expansion bulge is arranged on the top surface of the substrate; after this mosquito repellent subsides are attached on skin, the protruding thermal expansion inflation that is heated, then with the air pocket of the ejecting epirelief of seal membrane, be in the low pressure state in this air pocket, can assist the mosquito repellent to paste inseparabler absorption on the skin surface, effectively improve the fastness that the mosquito repellent pasted, glue stain can not appear when taking off simultaneously, effectively improve the travelling comfort of using.

Preferably, a gel layer is arranged on the surface of the packaging film opposite to the substrate; the gel layer can seal each flow guide hole during storage, so that the thermal expansion bulge is prevented from excessively expanding to form an air bag, and the mosquito repellent patch is prevented from volatilizing and leaking in advance; effectively ensures the air tightness and the service life of the mosquito repelling patch.
