Description

Technical Field

[0001] The utility model relates to the technical field of mosquito repellent equipment, and more specifically to the technical field of mosquito repellent signboards. Background Art

[0002] In addition to biting, sucking blood and harassing humans, mosquitoes can also spread diseases. There are four diseases in China that are transmitted by mosquitoes, namely dengue fever, epidemic encephalitis B, malaria and filariasis. The prevention and control of mosquitoes is an important means of controlling and eliminating mosquito-borne infectious diseases. Eliminating mosquito breeding grounds is the most fundamental way, so when necessary, use high-efficiency and low-toxic chemical pesticides. Common signs on the market only have the function of indicating information, and their functions are relatively simple, and they do not have a mosquito repellent effect. Existing patents disclose the following technologies:

[0003] The patent with the publication number CN217640520U and the patent name "Signage and mosquito repellent signage that can be installed with mosquito repellent sheet" discloses the following content: a signage and mosquito repellent signage that can be installed with mosquito repellent sheet. The signage that can be installed with mosquito repellent sheet includes a bottom plate and a sliding plate. A guide groove is provided on the bottom plate, and a storage groove for placing the mosquito repellent sheet is provided at the bottom of the guide groove, and slide grooves are provided on the two opposite side walls in the guide groove. A vent is provided on the sliding plate, and two opposite edges of the sliding plate are provided with connecting parts, and the two connecting parts are respectively slidably arranged in the two slide grooves. The sliding plate can slide in the guide groove, and the sliding plate has an open position and a closed position on its sliding track. When the sliding plate is in the closed position, the sliding plate blocks the opening of the storage groove, and the mosquito repellent sheet will not fall out of the storage groove; the vent will emit odor, which can repel mosquitoes. When the sliding plate is in the open position, the sliding plate and the storage groove are misaligned, and the user can install the mosquito repellent sheet in the storage groove or take out the mosquito repellent sheet for replacement. The sign on which the mosquito repellent sheet can be installed is easy to carry and convenient to use.

[0004] The patent with the publication number CN104964205A and the patent name "A bus station mosquito repellent billboard" discloses the following content: A bus station mosquito repellent billboard belongs to the field of advertising media technology. The billboard of the present invention includes a light source and a light guide plate. The light guide plate is arranged in front of the light source. The light source includes a light emitter and a shell. The shell is coated with a mosquito repellent fluorescent powder layer. The light guide plate is a transparent material that can absorb the blue spectrum. Specifically, the light guide plate is a yellow light guide plate. The billboard of the bus station of the present invention uses the characteristics of mosquitoes being afraid of green and red light to filter out the blue light emitted by the light source, so that mosquitoes stay away from the bus station, thereby achieving the mosquito repellent effect of the present invention.
