Electric heating liquid mosquito killer with controllable mosquito repellent liquid release concentration

Abstract

The invention discloses an electric heating liquid mosquito killer with a controllable mosquito repellent liquid release concentration. The electric heating liquid mosquito killer comprises an electric heating head (1) and a mosquito repellent liquid storage tank (2) matched with the electric heating head (1). A capillary cotton core (3) is arranged in the mosquito repellent liquid storage tank (2); and an atomization cavity (4) is formed in the electric heating head (1), and an atomization piece (5) is arranged at the bottom of the atomization cavity (4). One end of the capillary cotton core(3) extends into the bottom of the mosquito repellent liquid storage tank (2), and the other end of the capillary cotton core (3) extends out of the top of the mosquito repellent liquid storage tank (2) to be in contact with the bottom surface of an atomization piece (5). Effective components of mosquito-repellent liquid volatilize uniformly during working, the mosquito-repellent liquid is low inloss at normal temperature, and the release concentration of the mosquito-repellent liquid is controllable according to the size of space.

Description

technical field [0001] The invention relates to the technical field of mosquito coils, in particular to an electric heating liquid mosquito coil with controllable release concentration of mosquito repellent liquid. Background technique [0002] Mosquito coils are divided into two types: electric heating sheet mosquito coils and electric heating liquid mosquito coils. They both use the heating of heating elements to slowly release the medicine and volatilize the gas to kill and repel mosquitoes. The principle of the existing electric heating liquid mosquito-repellent incense device structure is that one end of the capillary cotton core is soaked in the mosquito repellent liquid, and an electric heating element is directly used around the top of the other end to heat around the end of the capillary cotton core, so that the capillary cotton soaked with the mosquito repellent liquid The core volatilizes mosquito repellent gas, and the electric heating liquid mosquito coil with t...

AI Technical Summary

Problems solved by technology

[0003] 1) Directly heat the outer periphery of the capillary cotton core. Due to the poor thermal conductivity of the capillary cotton core, the outer periphery of the capillary cotton core is heated more and the center is less heated, resulting in uneven distribution of the active ingredients of the mosquito repellent in the capillary cotton core, similar to that in alloys. The segregation phenomenon caused by the uneven distribution of each component element during crystallization will lead to uneven volatilization of active ingredients during the operation of the electric heating liquid mosquito coil, which will seriously affect the mosquito repellent effect;

[0004] 2) Because the existing structure uses capillary cotton core top peripheral heating, the end of the capillary cotton core must be close to the volatilization outlet of the mosquito coil device. When the mosquito coil device is not working, the convection between the capillary cotton core and the air is large, and the mosquito coil liquid at room temperature will continue to volatilize , resulting in rapid loss of mosquito repellent;

[0005] 3) Due to the continuous heating method directly on the periphery of the capillary cotton core, the volatilization of the mosquito repellent in the existing structure is fixed and uncontrollable, which means that no matter the size of the room, the volume of the mosquito repellent in the air cannot be changed according to the size of the used space. If the concentration is too low in a large room, the mosquito repellent effect will be poor, and if the concentration in a small room is too high, it will affect the health of the inhaler
