Description

Embedded type blowing charger baby

Technical Field

The utility model relates to an embedded blowing and charging device; the portable chest hanging rope is particularly suitable for being carried in a trip, hanging the back and the chest to be hung with the rope for blowing and placing the office desktop for blowing and charging.

Background

When the temperature rises in summer and people go out or work on the desk, a convenient tool for cooling the human body is particularly needed.

The traditional fan is large in size and inconvenient to carry during traveling; and general portable fan can only handheld use, restricts the activity of hand, and handheld restriction is dispelled the heat at front body and face, has restricted the back position of blowing, and the back is bloied the biggest area that the human body can directly blow, and the radiating effect is good, especially when sweating, takes away a large amount of heats. The treasured that charges is as the necessity when people's long-distance trip, and especially, people need carry two things of portable fan, treasured that charges simultaneously very inconvenient when going out.

The precious fan that charges is exposed now, and during the blowing, the fan position is easily drawn into the xenogenesis, perhaps the noise is great, and is not pleasing to the eye.

Disclosure of Invention

The utility model discloses an embedded treasured that charges of blowing to human cooling can only singlely be handheld or blow the face in solving current removal and desktop fan technique, can not relieve both hands and carry out the back heat dissipation of blowing in the removal, need carry components of a whole that can function independently fan and the precious problem of charging when charging the dual demand of blowing, also solve the precious fan that charges and be exposed, the fan position is easily drawn into the object when blowing, perhaps the great scheduling problem of noise.

The utility model comprises a charger, a turbofan and an air duct; the charger baby comprises an upper cover, a bottom cover, a control circuit board and a battery; two air inlet grids are arranged at one end of the left side and the right side of the upper cover close to the air outlet, an air outlet grid is arranged at the end part of the lower cover, the battery is tightly installed in the middle, and the control circuit board and the turbofan are respectively arranged at two sides of the battery; the control circuit board is arranged on the lower cover; the upper cover and the bottom cover are connected in a buckling manner to form an integral structure; the height of the cavity between the upper cover and the bottom cover is larger than the whole thickness of the turbofan; the turbofan is embedded in the charger baby; the turbofan air duct is arranged on the upper side of the turbofan blade; an air chamber is formed between the turbofan air duct and the upper cover; the air inlet of the turbofan is positioned at the side edge of the snail-shaped air channel; a miniature direct current high-speed motor is embedded in the turbofan blade, the turbofan blade is adhered to the air outlet grid side of the lower cover, and air is exhausted from the air outlet grid; the control circuit board comprises a booster circuit of the turbofan circuit; the upper cover is provided with two mounting ports, and two jacks of the control circuit board are matched with the two mounting ports of the upper cover; two sockets of the control circuit board are used for charging the battery and outputting and charging the battery; and the control circuit board can be used for boosting the turbofan circuit, so that the air output is ensured to be large enough and the speed can be adjusted.

The control circuit board can control the turbofan to rotate at low, medium and high third gear speeds, and different air output requirements are provided.

Wind is pumped into the wind chamber through the wind inlet grid, enters from the circular wind inlet of the wind channel of the turbofan, is pressurized by the rotation of the fan blade of the turbofan, and is blown out from the wind outlet grid; foreign matters are effectively prevented from entering the interior of the turbofan; the treasured that charges possesses mainstream interface, and quick charge satisfies most cell-phones or other consumer fast and stable charging on the market, safe and reliable to but function switch is as the fan.

The utility model has the advantages of: the waist can be hung to blow air to release two hands without holding the hands; the portable cooling fan is convenient to carry during traveling, can be fixed on the office table top and used as an office table top fan to take away sweat and cool a human body; meanwhile, the turbofan is adopted, so that compared with the traditional axial flow fan, the fan has the advantages of low noise and soft air volume; the problem of traditional precious fan that charges that the fan position exposes and the noise is solved.
