The drying method of the conventional air outlet device is usually that there is a certain distance between the air outlet device and the object to be dried, and the airflow generated by the air outlet device is directly blown to the object to be dried, and the moisture on the surface of the object to be dried is detached or evaporated by the impact of the air flow. Achieve drying. However, when the drying object is other parts of the human body such as hair and hands, the air outlet device has the disadvantages of poor usability and practicability. For example, when the air outlet device is a hair dryer, the airflow formed by the hair dryer is perpendicular to the head of the human body and impacts the hair. The hair is dispersed by the airflow, and the water on the surface of the hair is scattered to different areas, which is not easy to clean. Scattering is more likely to be entangled and knotted. In addition, the direction of the airflow hitting the hair is opposite to the growth direction of the cuticles, resulting in dry hair and poor suppleness. For example, when the air outlet device is a hand dryer, when the airflow formed by the hand dryer hits the hands of the human body, the moisture on the surface of the hand splashes into different areas of the inner cavity of the hand dryer, making it difficult to clean and less convenient to use.

Referring to FIG. 1 and FIG. 2 , an air outlet device is provided in an embodiment of the present invention to generate airflow to dry objects. The air outlet device includes an air outlet structure 100. The air outlet structure 100 includes a first air outlet part 110 and a second air outlet part 120. The second air outlet part 120 is sleeved outside the first air outlet part 110. The first air outlet There is an air outlet channel 130 between the part 110 and the second air outlet part 120, and one end of the air outlet channel 130 forms an air outlet 140, and the air flow can flow in the air outlet channel 130, and flow out of the air outlet channel 130 through the air outlet 140; The cross-sections of the first air outlet 110 and the second air outlet 120 are non-closed structures, and the sides of the first air outlet 110 and the second air outlet 120 are open. Therefore, the first air outlet 110 and the second air outlet The air outlet portion 120 has two endpoints in the circumferential direction of the air outlet structure 100. The air outlet structure 100 also includes a first end portion 150 and a second end portion 160. 100 are respectively connected to one end of the first air outlet 110 and one end of the second air outlet 120 in the circumferential direction, and the opposite sides of the second end 160 are respectively connected to the first air outlet along the circumferential direction of the air outlet structure 100 The other end of 110 and the other end of the second air outlet 120, the first end 150 and the second end 160 respectively close the two ends of the air outlet channel 130 in the circumferential direction of the air outlet structure 100, and the first end 150 There is a gap between the second end portion 160 and an opening 170 is defined. The side of the first air outlet portion 110 facing away from the second air outlet portion 120 defines an accommodating chamber 180 penetrating along the air outlet direction.

Since the airflow is not blowing vertically to the object to be dried, but flows along the extended surface of the object to be dried, it can avoid The object to be dried is scattered, and the moisture on the surface of the object to be dried falls along its own extension direction, and will not splash to the inside of the air outlet device, which is convenient for cleaning and maintenance, and has high convenience in use.

Specifically, when the air outlet device is used as a hair dryer, the user grabs the hair and puts the hair into the accommodating cavity 180 through the opening 170, the first air outlet part 110 is wrapped around the outer circumference of the hair, and the air outlet of the air outlet structure 100 140 is towards the tail of the hair, the airflow blown out through the air outlet 140 flows to the surface of the hair, and takes away the moisture on the surface of the hair, so as to realize the drying of the hair. Since the air outlet structure 100 is wrapped around the outside of the hair, it can prevent the hair from During the drying process, it scatter around, even entangled and knotted; it should be noted that since the flow direction of the airflow is the same as the growth direction of the hair cuticles, the airflow blows the hair cuticles to close during the drying process, making the hair more supple after drying. When the air outlet device is used as a hand dryer, the wrist or arm of the human body enters the accommodating cavity 180 through the opening 170, the air outlet structure 100 is wrapped around the outside of the wrist or arm, and the air outlet 140 faces the hand. The airflow discharged from the air outlet 140 is blown to the surface of the hand along the extension direction of the finger, and the moisture is taken away to realize the drying of the hand; it should be noted that since the airflow flows along the surface of the hand, the moisture on the surface of the hand is driven by the airflow Dropping directly downwards without splashing into the inside of the air outlet device can reduce liquid residue inside the air outlet device and facilitate cleaning and maintenance.

It should be noted that, in order to facilitate putting the object to be dried into the accommodating chamber 180 through the opening 170, in this embodiment, the accommodating chamber 180 and the opening 170 both penetrate the air outlet structure 100 along the air outlet direction of the air outlet channel 130, so as to avoid waiting The dried object interferes with the air outlet structure 100 during the process of being placed into the accommodating cavity 180 . The air outlet device also includes an air induction structure 200 for generating airflow. The airflow generated by the air introduction structure 200 enters the air outlet channel 130 and is discharged from the air outlet 140 to dry the object to be dried.

Specifically, the air outlet device further includes a fixed structure 300 connected to the outer peripheral surface of the second air outlet portion 120 , the fixed structure 300 has an air-introduction cavity 310 inside, and the air-induction structure 200 is accommodated in the air-induction cavity 310 . The fixed structure 300 can be a handle for the user to hold, so that the user can hold the air outlet device to dry, and can flexibly adjust the angle of the air outlet structure 100, the position of the opening 170, etc. according to the needs, which has a high degree of convenience, such as When the air outlet device is a hair dryer, the fixed structure 300 is set to a handle, and the air outlet structure 100 is an air outlet; Seat, the fixed seat can be installed and fixed on the installation surface (such as wall, washstand), so that the air outlet structure 100 is in a fixed state. For example, when the air outlet device is a hand dryer, the fixed structure 300 is on the hand dryer. Fixing seat for fixing.

The fixed structure 300 also has an air inlet 320, the air inlet 320 communicates with the air-introducing chamber 310, the air-introducing chamber 310 communicates with the air-out channel 130, the external air can enter the air-inducing chamber 310 from the air inlet 320, and is subjected to the air-introducing structure. Driven by 200 , an airflow is formed, and the airflow enters the air outlet channel 130 from the air induction cavity 310 , passes through the air outlet channel 130 , and is discharged from the air outlet 140 . Further, in one embodiment, the air inlet 320 is set at the end of the fixed structure 300 away from the air outlet structure 100. When the user uses the air outlet device, the user can hold the middle area of the fixed structure 300 or the area close to the air outlet structure 100, which can Avoid the air inlet 320 to avoid blocking the air inlet 320 and affecting the air intake of the air inlet 320 . There are multiple air inlets 320 , and the plurality of air inlets 320 are distributed at intervals along the circumference of the fixed structure 300 to increase the air inlet area of the fixed structure 300 and improve the air outlet efficiency of the air outlet structure 100 .

The air-introduction chamber 310 forms a through hole near the end of the air inlet structure, and the through hole communicates with the side of the air outlet channel 130. The airflow entering the air outlet channel 130 from the through hole is received by the first air outlet part 110 and the second air outlet part 120 to flow toward the air outlet 140, and finally blow out from the air outlet 140. In some embodiments, the opening 170 is located on the side of the air outlet structure 100 facing away from the fixed structure 300 , that is, the opening 170 is opposite to the fixed structure 300 and located on both sides of the air outlet structure 100 , and the air outlet structure 100 is opposite to the opening 170 The central plane of the air outlet channel 130 is divided into two parts with respect to the central plane of the opening 170. In this way, the airflow entering the air outlet channel 130 from the through hole passes between the first air outlet part 110 and the second air outlet part. Guided by 120, it is divided into two parts, and enters both sides of the air outlet channel 130 respectively. Since the air outlet structure 100 has an opening 170, the airflow in the air outlet channel 130 will not form a closed loop on the side facing away from the fixed structure 300, but The closed-loop airflow will affect the airflow distribution on both sides of the air outlet channel 130, resulting in damage to the air outlet efficiency and wind pressure.

As shown in Figures 3 to 6, the opening 170 is arranged on the side of the air outlet structure 100 facing away from the fixed structure 300, and the airflow blown out from the air induction cavity 310 is divided into two paths and enters the two sides of the air outlet channel 130 respectively, and the two parts The airflows will not merge again in the air outlet channel 130 to form a closed loop, and collide with each other to form turbulent flow, thereby affecting the air outlet effect. As shown in FIG. 7 , in some embodiments, the position of the opening 170 is set such that the center plane of the opening 170 in the radial direction of the air outlet structure 100 is between the center plane of the fixed structure 300 in the radial direction of the air outlet structure 100 The angle between them is less than 180°, that is, 0°∠a≤180°. The position of the opening 170 deviates from the side of the air outlet structure 100 facing away from the fixed structure 300. When the user uses the air outlet device, hold the fixed structure 300 and hold the opening 170 faces the object to be dried, which is more convenient to use. For example, when the air outlet device is used as a hair dryer, the user holds the fixed structure 300 and places the air outlet structure 100 on one side of the head. At this time, the opening 170 is just facing the hair, and the hair can be more conveniently placed in the accommodating cavity 180. .
