Portable multifunctional infant clean air blower

Abstract

The invention relates to the field of an air purification device, and particularly relates to a portable multifunctional infant clean air blower. The portable multifunctional infant clean air blower comprises a chassis and a fan combination, a filtering device and a detection device which are arranged in the chassis; the fan combination and the filtering device are positioned at the lower segmentof the chassis; the filtering device is positioned at the lower end of the fan combination; the detection device is positioned at the upper segment of the chassis; and a functional key group is arranged at the top of the upper segment of the chassis. According to the invention, the supercharging principle of a turbofan is utilized to obtain high-flow clean air under the condition of a small air opening area; the output air volume is large; surrounding air can be rapidly filtered; the purification effect is good; a novel structure is adopted; the sealing performance is good; the portable multifunctional infant clean air blower is simple in structure, small in volume, convenient to carry, convenient to use and suitable for various indoor and outdoor use scenes, can take effects of filteringthe air and cooling; and meanwhile, real-time numerical values of PM2.5 particles, the temperature and the humidity of the environment where the portable multifunctional infant clean air blower is located can be detected.

Description

technical field [0001] The invention relates to the field of air purification devices, in particular to a portable multifunctional clean air blower for infants. Background technique [0002] In people's daily life activities, they often encounter some environments with poor air, especially when infants and young children are in some public places, such as in crowded places, places with poor air circulation, and on the road, because the air in these places will be relatively poor or It is relatively stuffy, so it has a serious impact on the health of infants and young children. The appearance of portable air purifiers has greatly reduced the threat of the environment to infants and young children. However, for the current portable air purifiers, one of the factors affecting the purification efficiency of the purifier is the output air volume. According to the air volume Q is equal to the product of the wind speed V and the cross-sectional area of ​​the air duct F. That is; Q=...

Problems solved by technology

However, for the current portable air purifiers, one of the factors affecting the purification efficiency of the purifier is the output air volume. According to the air volume Q is equal to the product of the wind speed V and the cross-sectional area of ​​the air duct F. That is; Q=VF, where the air volume calibrated by the fan determines the purification The maximum output air volume that can be obtained by the air purifier. Due to the limitation of small size, the current portable air purifiers all use small axial flow fans to supply air. In order to reduce the wind resistance of the air outlet and obtain the maximum output air volume, they all use large air purifiers. Due to the above reasons, the wind speed of the air outlet of the current portable air purifier is very low, generally 1 m / s, and the air supply distance is short, so its use can only be placed in a small space The air in a small space is filtered through a certain period of time, but the filtered clean air cannot be directly and quickly blown to the user, especially in a large space with poor air quality and high temperature or outdoor use, the user cannot breathe in time Clean air can't get the experience of cool breeze

[0003] Due to the low wind speed, the portable air purifiers currently on the market do not have the function of sweeping the air and have a single function. They cannot not only have the characteristics of infant products, but also provide timely clean air and cooling effects for infants and young children in various indoor and outdoor use scenarios.
