Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a mosquito repellent fan. Background Art

[0002] An electric fan is an electrically driven device that generates airflow. When powered, the blades rotate, converting mechanical energy into wind energy, which in turn creates a natural breeze for a cooling effect. When the weather is hot, people often use electric fans to cool down. However, hot weather is often accompanied by the presence of mosquitoes. Mosquito bites can cause redness, swelling, and itching on the skin, disrupting rest. Some mosquitoes can even spread diseases such as dengue fever and malaria.

[0003] Mosquito repellent fans are available on the market. These typically use liquid mosquito coils installed on the fan. The liquid is driven by the fan to disperse, effectively repelling / killing mosquitoes. Once the liquid coil is used up, the liquid must be replaced (by rotating and removing the liquid bottle). However, this is inconvenient due to the narrow cavity in which the liquid coil is installed.

[0004] For example, the mosquito repellent fan disclosed in Chinese patent application number CN202410426139.6 specifically discloses that "the installation space runs through opposite sides of the support base, the upper end of the installation space has an installation position, a heating position is provided in the support base above the installation space, a heating element connected to the electronic control device is provided in the heating position, the support base is provided with a clearance hole, the clearance hole connects the heating position and the installation space, the installation position is used to install bottled electric mosquito repellent liquid, and the clearance hole is used to clear the liquid guide core of the electric mosquito repellent liquid." It can be seen that the installation position is small, and it is inconvenient to replace the electric mosquito repellent liquid after it is used up.

[0005] Another example is the mosquito repellent fan disclosed in Chinese patent application number CN202221696284.9, which specifically states that "the second chamber is used to place a mosquito repellent liquid bottle, a first heating seat is provided in the first chamber, a second heating seat is provided in the second chamber, the first heating seat and the second heating seat are respectively electrically connected to a switch assembly, the first heating seat is used to heat the mosquito coil, and the second heating seat is used to heat the heating rod of the mosquito repellent liquid bottle." Clearly, the space in the second chamber is also very small, making it inconvenient to replace the mosquito coil liquid. Utility Model Content
