Description

Portable low-power consumption electric mosquito repellent

Technical Field

The invention relates to the technical field of mosquito repelling devices, in particular to an electric mosquito repellent.

Background

In hot summer, mosquito bites are a long-term puzzlement for people, so people invent various mosquito repelling and preventing articles, and an important one is mosquito repellent incense. In addition to the traditional disc type mosquito-repellent incense, people also invent electric mosquito-repellent incense, and the working principle of the electric mosquito-repellent incense is that the mosquito-repellent agent is baked by heating through electric energy, so that the mosquito-repellent agent is atomized, volatilized and diffused to an external space, and the mosquito-repellent effect is achieved. For example, chinese patent CN 201020049447.5 discloses an electric heating mosquito and fly repelling device, which comprises an electric heater and a liquid storage bottle connected with the electric heater, and is characterized in that a liquid suction tube is inserted into the liquid storage bottle, a cotton swab is inserted into the liquid suction tube, and one end of the cotton swab, which is located outside the liquid storage bottle, is connected with the electric heater.

The electric mosquito incense in the prior art can achieve the effect of repelling mosquitoes and flies, but has the following defects: 1. although the mosquito-repellent incense liquid bottle in the prior art can be replaced, only the mosquito-repellent incense liquid bottle is replaced, and the electric heater for heating and atomizing is not replaced together, but in practice, the electric heater is a part which is most easy to age and damage due to long-time heating, and the electric heater is aged to cause insufficient power, so that the effective components for repelling mosquitoes are not volatilized or are insufficient in concentration. 2. The mosquito-repellent incense liquid bottle is replaced independently, the installation precision is difficult to grasp, and the installation precision of the mosquito-repellent incense liquid bottle can influence the mosquito-repellent effect. 3. In order to convey the mosquito-repellent incense liquid to the upper end, a thick cotton stick is required, but the washing liquid amount of the thick cotton stick is large, so that the liquid guiding amount cannot be accurately controlled; people hope to realize accurate control on the using amount of the mosquito-repellent incense liquid, the liquid guiding amount is too small, the mosquito-repellent effect cannot be realized, the liquid guiding amount is too large, the mosquito-repellent incense liquid is consumed quickly, and the mosquito-repellent incense liquid is harmful to human bodies. 4. The cotton swab leads liquid measure greatly and just requires electric heater's use forceful electric power just can satisfy the requirement, and the power is too low can not reach the atomizing effect, so prior art's electric mosquito repellent makes power consumption great because of using the forceful electric power to use the forceful electric power to exist because of forgetting to close or pull out the potential safety hazard that causes. 5. Because lead among the prior art oily cotton stick and be mostly inflammable material, for ensureing safety, the heater usually not with lead oily cotton stick direct contact, and adopt peripheral baking mode to realize atomizing, but this mode makes the power consumption increase of electric mosquito repellent.
