Heater for heating mosquito-killing liquid using high-frequency electromagnetic heating

Abstract

The present invention discloses a heater for heating mosquito-killing liquid using high-frequency electromagnetic heating. The heater for heating the mosquito-killing liquid using the high-frequency electromagnetic heating comprises a high-frequency electromagnetic heating circuit and a heating rod; the heating rod is a carbon rod or a cotton rod with a metal inner core; the high-frequency electromagnetic heating circuit comprises a power source with an output of 3-6 V, high-frequency resonant capacitors, a heating coil, a master control single chip microcomputer with a chip model of PIC12F629and MOS tubes; the heating coil is wound into a ring structure; the heating rod is located in the heating coil; the power supply supplies powder for the high-frequency resonant capacitors, heating coil and master control single chip microcomputer; the master control single chip microcomputer is respectively connected with the high-frequency resonant capacitors and heating coil via the MOS tubes;and the master control single chip microcomputer controls power of the heating coil. The carbon rod or a water absorption rod with the metal inner core is directly heated to reduce heat loss by heat transfer; and the heater achieves high-efficiency, low-power-consumption and fast-heating characteristics, uses 3-5 V power supply, is safe and low in cost, has the heating power of 0.6 W-1 W, can supply power for batteries, enhances mobility and realizes outdoor applications.

Description

technical field [0001] The invention relates to the field of electric mosquito-repellent incense heaters, in particular to a heater for heating mosquito-repellent incense liquid by using high-frequency electromagnetic. Background technique [0002] Mosquito repellent also is the important living environment problem that people face always. Insects such as mosquitoes and flies really disturb people's normal life very much in summer, so people often need a plate of mosquito coils to repel mosquitoes in summer nights. Electric mosquito-repellent incense is a small household appliance that uses heat-formed mosquito-repellent incense sheets or mosquito-repellent liquid to repel mosquitoes. Compared with other directly ignited mosquito coils, the advantage is that it is easy to operate, safer, and has more effective mosquito repellent ingredients. [0003] The existing electric mosquito coil heaters mainly use resistance wire heating, and the high-end ones use PTC thermistors to...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned electric mosquito-repellent coil heater has the following problems: 1. The use of 220V mains power supply has potential safety hazards, and the use position of the electric mosquito-repellent coil heater will be greatly limited by the position of the AC socket

2. Electric mosquito coil heaters generally have a heating power of 3-5 watts, and the power consumption is relatively high
