Description

Technical Field

[0001] The utility model belongs to the technical field of fans, and in particular relates to a low-noise refrigeration fan. Background Art

[0002] Noise reduction fans are fan devices that provide a quiet environment by reducing noise pollution. As people's requirements for quality of life increase, noise pollution in home and office environments has received increasing attention. Traditional fans generate a lot of noise when working, especially when running at high speeds, which not only affects the user's comfort, but may also have adverse effects on hearing health.

[0003] The existing dust-proof electric fan (publication number: CN211599045U) generally has the following problems during use:

[0004] 1. Lack of noise reduction structure: Noise pollution: Affects sleep quality: High noise levels can disturb users' sleep, especially when using the fan at night. Continuous noise may cause insomnia or shallow sleep, affecting the overall quality of rest. Affects work efficiency: In an office or learning environment, fan noise can distract attention and reduce work and study efficiency. Health issues: Hearing damage: Long-term exposure to high noise environments may cause hearing damage, especially for children and the elderly. Psychological stress: Continuous noise can cause psychological stress and irritability, affecting mental health. Poor user experience: Reduced comfort: Excessive noise may make users feel uncomfortable, thereby reducing their satisfaction with the product. Negative reviews: High noise will lead to negative user reviews of the product, affecting brand reputation and market competitiveness, so there is an urgent need for a cooling fan with a noise reduction structure.

[0005] 2. Lack of remote control structure: User inconvenience: Manual operation is cumbersome: Users need to frequently manually adjust the settings of the fan, such as switch, wind speed, mode, etc., which is very inconvenient, especially at night or when it is inconvenient to move around. Not suitable for smart home environment: With the popularity of smart homes, fans without remote control functions are difficult to integrate into smart home systems and cannot be controlled by mobile phones or voice assistants, which reduces the convenience of use. Energy waste: Unable to turn off in time: Users may forget to turn off the fan due to inconvenience, resulting in energy waste. If it can be turned off in time through remote control, electricity can be significantly saved. Unable to adjust according to demand: Failure to adjust the fan settings in time according to actual needs may lead to excessive use or unnecessary energy consumption. Reduced comfort: Unable to respond to demand quickly: When the ambient temperature or user needs change, it is impossible to respond quickly through remote control, which may cause users to feel uncomfortable. Unable to preset the environment: Users cannot turn on the fan in advance before returning home to adjust the indoor temperature and reduce waiting time, which reduces the comfort of use, so a remote-controlled cooling fan is urgently needed.

[0006] 3. The overall structure is large and inconvenient to carry: Poor portability: Not suitable for travel: Large cooling fans are difficult to carry when traveling, limiting their application in tourism, camping, etc. Large space occupation: Occupies family space: Large fans occupy more use space in small apartments or rooms with limited space, affecting the layout and appearance of the room, so there is an urgent need for a cooling fan that is easy to carry.
