Self-adaption electric mosquito-repellent incense device

Abstract

The invention provides a self-adaption electric mosquito-repellent incense device, and belongs to household appliances. The self-adaption electric mosquito-repellent incense device comprises a shell, wherein a heating plate and an indicating lamp are arranged above the shell; a concentration inductor for detecting the concentration of sensitive gas in air at the periphery of the electric mosquito-repellent incense device is also arranged on the shell; the concentration inductor is electrically connected with the control end of a heating control module for controlling heating power; the input end of the heating control module is connected with a power supply, and the output end of the heating control module is connected with the heating plate and the indicating lamp; and when a concentration signal of the sensitive gas sensed by the concentration inductor is smaller, the output of the heating control module is larger. In the electric mosquito-repellent incense device, the heating power can be adjusted in real time according to the residual dose of an electric mosquito-repellent incense tablet, and the residual does condition of the electric mosquito-repellent incense tablet is indicated simultaneously, so the concentration of sensitive smell is homogenized, and resources are saved.

Description

Technical field [0001] The invention relates to a household electrical appliance, in particular, an electric mosquito coil, which includes a casing and a heating plate. Background technique [0002] Electric mosquito-repellent incense is currently the most common small household appliance. Because there are many mosquitoes in summer, the use of ordinary mosquito-repellent incense has problems such as heavy smoke and high fire hazards. Therefore, electric mosquito-repellent incense has basically replaced ordinary mosquito-repellent incense and has become a must-have in summer. supplies. The electric mosquito-repellent incense device mainly relies on a heating plate above the shell to heat the electric mosquito-repellent incense sheet to make it emit mosquito-sensitive odor, thereby killing mosquitoes. However, the problem with the electric mosquito-repellent incense device is that it is difficult to distinguish the consumption of the mosquito-repellent-repellent incense shee...

AI Technical Summary

Problems solved by technology

However, the problem with the electric mosquito-repellent incense device is that it is difficult to distinguish the consumption of the mosquito-repellent-repellent incense sheet when the electric mosquito-repellent-repellent-repellent incense sheet is in use, and the heating power of the heating plate is fixed. Strong sensitive smell, and after a long heating time, the concentration will decrease a lot, and even the sensitive smell will no longer be produced. Since this kind of sensitive smell is generally difficult for humans to detect, it is impossible to know how much the electric mosquito-repellent-repellent-repellent-repellent incense is consumed. The sensitive smell emitted by the electric mosquito-repellent incense is not uniform. On the other hand, in order to ensure the mosquito-killing effect, the user often replaces a new electric mosquito-repellent incense every time the electric mosquito-repellent incense is turned on, which will cause a large waste of resources.
