Description

Technical Field

[0001] The utility model relates to the field of fans, in particular to a fan for a baby carriage. Background Art

[0002] A fan is a common small electrical appliance used to generate air flow to provide cooling or ventilation. The fan pushes air by rotating blades, thereby creating a flow and lowering the surrounding temperature. Fans are used in many scenarios, and some strollers also choose to install fans for heat dissipation to improve the comfort of the baby.

[0003] Fans can effectively dissipate heat and provide a comfortable environment, but there are still some problems: 1) They do not have an air filtering effect. When the wind blows the outside air into the stroller, a large amount of dust will also be inhaled, causing harm to the health of the baby; 2) They cannot monitor the air temperature and air quality; 3) They cannot automatically adjust the wind speed according to the ambient temperature, and the air output is not soft and diffuse enough; Therefore, in view of the above situation, it is urgent to develop a fan for baby strollers to overcome the shortcomings in current practical applications and meet current needs.
