Description

Technical Field

[0001] The utility model relates to the field of insect repeller technology, in particular to an ultrasonic insect repeller. Background Art

[0002] The home environment is prone to breeding many harmful insects, causing harm and trouble to people's lives. To solve this problem, people usually take chemical methods, such as using anthelmintics and insecticides, which are harmful to both humans and pets, and the hygiene of the home environment will also be affected to a certain extent.

[0003] The traditional mosquito killing method is to attract mosquitoes through light. However, this mosquito killing lamp can only kill mosquitoes and has a single function, which is to lure and kill pests. In addition to the harm caused by pests in daily life, rats and other pests also bring troubles to people's lives. For this reason, some ultrasonic insect repellents have been born. Although the existing ultrasonic insect repellents can repel mosquitoes, rats, cockroaches and other pests through ultrasonic waves, their emission windows are usually only set on the front. Although this can meet the emission of ultrasonic waves, it is limited by the emission window set on the front. When it is applied to the corner of the house, the socket interface is facing away from the wall. When it is inserted into the socket, its emission window is facing away from the wall. It still emits toward the front and cannot directly face the corner sideways to repel insects in the corner, resulting in poor insect repellent effect.

[0004] Therefore, it is necessary to develop a new technology to solve the above problems. Utility Model Content
