It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] As Figure 1As shown, the portable electric heating mosquito repellent device of the present application mainly comprises a device shell and a heating area 2, an information display area 3 and a human-computer interaction area 4 arranged thereon, the repellent 1 is detachably and replaceably mounted on the heating area 2, and the device is powered by a detachable power supply element (which can be a dry battery, a rechargeable battery or a solar panel, not shown in the figure).

[0029] Specifically, the information display area 3 in the portable electric heating mosquito repellent device of the present application can be provided with a plurality of indicator lights or a single display screen to display the current working temperature value, the current power supply element power and time information and the like of the device; the human-computer interaction area 4 is provided with a plurality of keys to control the on-off and specific temperature gear of the device.

[0030] The repellent 1 of the present application comprises picaridin (also known as: icaridin), repellent ester, repellent amine and methyl nonyl ketone, and is combined with different carriers or adjuvants, and the repellent 1 can be made into various forms. In an embodiment of the present application, the form of the repellent 1 is gelatinous, which is prepared by the following method:

[0031] Step one: mix 0.35wt% carbomer, 4wt% butanediol and 59.66wt% sterile water, continuously stir until uniform, then heat to 85℃, keep warm for 30min, and homogenize for 5min to obtain an initial solution;

[0032] Step two: cool the initial solution to 50℃, add 0.18wt% aminomethyl propanol, stir until uniform to obtain an intermediate solution;

[0033] Step three: add 15wt% ethanol, 20wt% repellent, 0.3wt% triethyl citrate, 0.05wt% glyceryl caprylate and 0.46wt% preservative to the intermediate solution, stir until uniform, and the gelatinous repellent is obtained.

[0034] In another embodiment of the present application, the form of the repellent 1 is paste, which is prepared by the following method:

[0035] Step one: weigh 10-15g of collagen protein powder into 200-300g of deionized water, stir and mix until uniform to obtain a collagen protein solution, then add 6-8g of cellulose, 3-5g of glycerol, 1-2g of stearic acid and 1-2g of sodium dodecyl sulfate to the collagen protein solution, adjust the pH value to 10-11 with 15wt% sodium hydroxide solution, heat to 85-88℃ after adjustment, stir and mix for 50-60min, cool to room temperature after stirring, and obtain a viscous liquid for standby;

[0036] Step two: organic curing agent (such as vaseline, balsam of peru), in 70~80℃ water bath for 0.5 hours, become solution after; Add repellent drug liquid, stirring 3-5min, in 0~5℃ temperature cold storage curing 3~5h, after curing from the container, get solid paste;

[0037] Step three: the above solid paste is added to the viscous liquid prepared in step one at a mass ratio of 1:5; stir for 3-5min, and dry naturally for 6-8h to obtain the repellent ointment.

[0038] In another embodiment of the present application, the repellent drug 1 is carried by the adsorbent material (such as flexible non-woven fabric).

[0039] In another embodiment of the present application, the repellent drug 1 is in the form of a tablet, which can be formed by mixing the repellent drug with a clathrate agent (such as crown ether, cyclodextrin, calixarene, calixpyrrole, calixcarbazole, cucurbituril, pillararene) and drying to form a solid, and then pressing into a tablet. In this embodiment, the heating area 2 can be provided with a mounting groove to accommodate the repellent drug 1, or a rotating buckle to rotate and tighten the repellent drug 1, thereby mounting the repellent drug 1 on the heating area 2.

[0040] The repellent drug used in the present application will gradually accelerate the volatilization speed under heating conditions, but when the heating temperature exceeds 120℃, the volatilization speed will rapidly increase, resulting in premature consumption of the drug. In the present application, the working temperature of the heating area 2 is set to be greater than 40℃ and less than 120℃, and multiple temperature gears are set in this interval, which can be adjusted by operating in the human-computer interaction area 4. The minimum value of the interval is 40℃, which is higher than the normal body temperature of human body, and the maximum value of the interval is 120℃, which is the upper limit temperature of the maximum reasonable diffusion rate of the repellent drug.

[0041] The present application uses the heating area 2 to heat the repellent drug 1, so that the repellent drug 1 diffuses into the air, thereby achieving the effect of mosquito control. The working temperature of the repellent drug used in the present application is relatively low, so that the power consumption of the device is relatively low, the endurance performance is good, and the device can be matched with smaller power supply elements, so that the device is more lightweight.

[0042] The above embodiments only express the implementation of the present application, which is described in detail and specifically, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of protection of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
