Detailed Description

The present application is described in further detail below with reference to the attached drawings.

At present, a blower is generally provided with a driving motor and fan blades on an air duct, and the driving motor is controlled by a switch on a handle to drive the fan blades to rotate to stir air flow, so that a large amount of air is blown out. During use, the increased flow rate of the blown air results in increased evaporation of the water vapor. And set up heating element in the dryer, can make the wind that the hair-dryer blew out be the warm braw, further accelerate the steam evaporation. The hair dryer is often used to dry hair or clothes in life.

The dryer may be used to dry hair for pets, in addition to its own use. When the pet is dried, the pet needs to be combed at the same time. For pets with larger body sizes, the greater the range of hair drying needs to be. When the handle is held for hair drying, the direction of the air outlet of the air duct is not easy to control, and the use is troublesome. In addition, in barbershops, hair stylists do not leave hair dryers in order to create an originally designed hair style. Under the general condition, in order to make a hairstyle more quickly, a hairstyle designer can also hold the air outlet of the air duct, so that the air outlet direction of the hair dryer can be controlled more conveniently. However, under the condition that the air duct from the air blowing port blows warm air, the temperature of the air duct is gradually increased along with the increase of time, and people are easily scalded. In view of the above circumstances, the existing hair dryer has the defect that the air outlet direction is not convenient to control in use.

The embodiment of the application discloses a portable air blowing tube. Referring to fig. 1, the portable hair dryer includes a dryer body 1, a handle 2, and an arc-shaped connector 3. Arc connecting piece 3 sets up the tip of dryer body 1 to be provided with arcwall face 31 on the arc connecting piece 3, handle 2 carries out sliding connection along arcwall face 31 and arc connecting piece 3. By changing the position of the handle 2, the air outlet direction of the air blowing tube controlled by the handle 2 is correspondingly changed. When the air-blowing device is used in different scenes, the position of the handle 2 can be adjusted at any time according to the scene requirements, so that the air-blowing direction of the air-blowing barrel is easier to control.

Referring to fig. 2, an air cavity 11 is formed in the air duct body 1, the air cavity 11 is used for air flowing, and an air outlet is formed in one end, far away from the arc-shaped connecting piece 3, of the air duct body 1. A baffle plate 12, a wind power driving motor 13 and a heating element 14 are provided in the wind chamber 11. Baffle 12 is fixed on the inner wall of dryer body 1 in the joint, and wind-force driving motor 13 is fixed on baffle 12. The baffle 12 is provided with a through hole to facilitate the air to enter the wind power driving motor 13 from the wind cavity 11, thereby realizing the flow acceleration of the air. The heating element 14 is arranged between the air outlet and the wind power driving motor 13, and after the wind power driving motor 13 accelerates the air flow, the air passes through the heating element 14 and takes away heat, so that the air output by the air outlet is changed into warm air.

In the present embodiment, when the handle 2 covers the first air inlet 32, the longitudinal direction of the handle 2 and the longitudinal direction of the air cylinder body 1 are perpendicular to each other. When the handle 2 covers the second air inlet 33, the longitudinal direction of the handle 2 and the longitudinal direction of the air cylinder body 1 are parallel to each other.

When the handle 2 and the air cylinder body 1 are perpendicular to each other, air enters from the second air inlet 33 and is exhausted from the air outlet after being accelerated by the wind power driving motor 13, and at the moment, the handle 2 and the air cylinder body 1 are in a perpendicular mode and can be used for blowing in a common use scene. When the handle 2 and the air cylinder body 1 are parallel to each other, air enters from the first air inlet 32 and is exhausted from the air outlet after being accelerated by the wind power driving motor 13, and at the moment, the handle 2 and the air cylinder body 1 are in a parallel mode. When the air-blowing device is used, the handle 2 is held by hand, and the air-out direction of the air-blowing cylinder is the same as the length direction of the handle 2. When carrying out hair to the pet and weather, can hold handle 2 and can also comb hair when blowing at the air outlet department installation comb of dryer body 1. Because the length direction of the handle 2 is the same as the air outlet direction, the air outlet direction of the air blowing barrel is easier to control. Similarly, for the hair stylist, when the air outlet direction needs to be accurately controlled, the handle 2 is adjusted to be parallel to the air duct body 1, so that the control is better facilitated.
