Description

Technical Field

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

[0002] The home environment is prone to breeding many harmful insects, which bring harm and annoyance to people's lives. To solve this problem, people usually adopt chemical methods, such as putting insect repellent and insecticidal drugs, which are harmful to both humans and pets to a certain extent, and the home environmental hygiene will also be affected to a certain extent.

[0003] Traditional mosquito killing methods can attract mosquitoes through light. However, this kind of mosquito killing lamp can only kill mosquitoes and has a single function, only the function of attracting and killing pests. In daily life, in addition to the harm of pests, there are also mice and the like that bring annoyance to people's lives. For this reason, some ultrasonic insect repellents have emerged one after another. Although the existing ultrasonic insect repellents can drive pests such as mosquitoes, mice, and cockroaches through ultrasonic waves, their emission windows are usually only set on the front. Although this can meet the emission of ultrasonic waves, limited by the emission window set on the front, when it is applied to the corner of a 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, and it still emits towards the front, unable to directly face the corner or the ground laterally to directly repel insects in the corner or on the ground, resulting in poor insect repellent effect.

[0004] Therefore, it is necessary to research a new technology to solve the above problems. Summary of the Utility Model
