[0019] The present application is described in further detail below. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1

[0021] like Figure 1-3As shown, a down drying device convenient for recycling and outputting down includes a drying box 1, the drying box 1 is provided with a feeding port 2 for feeding wet down and a discharging port 3 for outputting dry down, the box wall of the drying box 1 is provided with more than two annular cavities 4 in sequence from top to bottom, and more than two spray holes 5 for spraying hot air obliquely upward are provided at equal distances between the annular cavity 4 and the inner cavity of the drying box 1 along the circumference of the annular cavity 4, the amount of hot air sprayed from the spray holes 5 gradually increases from top to bottom, and the annular cavity 4 is provided with an air pipe for inputting hot air inward, and the air pipe leads to a blower.

[0022] As a further solution of the present invention, the size of the spray hole 5 provided on the same annular cavity 4 increases as the distance between the spray hole 5 and the corresponding air pipe increases, so that the air flow rate sprayed by the spray hole 5 provided on the same annular cavity 4 is the same.

[0023] In the above embodiment, hot air is introduced into the annular cavity 4 on the drying box 1 through a blower. After the hot air fills the annular cavity 4, it is sprayed into the interior of the drying box 1 from the multiple spray holes 5 on the annular cavity 4. Because the spray holes 5 are arranged at an angle, the hot air sprayed from the spray holes 5 is inclined upward. Then, the wet down is put into the drying box 1 from the feeding port 2, and the down is blocked by the upward moving hot air during the falling process. Driven by the hot air, the falling speed of the down is slowed down, and it stops falling when it reaches the annular cavity 4 at the bottom, and it shakes in the drying box 1 driven by the hot air, that is, the down is in a floating state in the inner cavity of the drying box 1. When the down changes from a wet state to a dry state, the input of hot air is stopped, and the down moves downward under the action of its own gravity and moves out of the drying box 1 from the discharge port 3.

[0024] Among them, different nozzle holes 5 at the same horizontal height have different sizes, so that the hot air can be evenly ejected from different nozzle holes 5 during the movement in the annular cavity 4, avoiding the down being deflected in the drying box 1 due to a large amount of air ejected from the nozzle holes 5 close to the air pipe.

[0025] As a further solution of the present invention, a mounting seat 6 is provided at the top of the inner cavity of the drying box 1, a rotatable shaft 7 is provided at the bottom of the mounting seat 6, a folding fan is provided at the bottom end of the shaft 7, hot air ejected from the spray hole 5 at the bottom of the drying box 1 faces the folding fan, a movable fan 8 for cleaning down on the surface of the shaft 7 is provided on the shaft 7, and the movable fan 8 rotates and blows air downwards under the drive of the folding fan;

[0026] The folding fan includes a base 9 and blades 10. The side wall of the base 9 is provided with more than two mounting grooves 11 along the circumference of the rotating shaft 7. The blades 10 are hingedly mounted in the mounting grooves 11. The top of the base 9 is an arc-shaped structure.

[0027] In the above embodiment, by providing the base 9 and the fan blade 10, when the nozzle 5 blows hot air toward the fan blade 10, the fan blade 10 is driven upward, and when the fan blade 10 rotates to a horizontal state, it stops rotating, and driven by the hot air, the base 9 and the fan blade 10 rotate radially along the rotating shaft 7. At this time, the rotating shaft 7 is driven synchronously, so that the mobile fan 8 rotates. The mobile fan 8 generates a downward airflow when rotating, and the mobile fan 8 gradually moves upward under the dual force of the hot air and its own rotation. In the process of the mobile fan 8 moving upward, the down in the drying box 1 can be scattered, which helps to reduce the agglomeration of the down. In addition, the downward airflow can prevent the down from floating upward, reduce the adhesion of the down to the drying box 1 and the loss of the down. When the mobile fan 8 moves to the top of the drying box 1, it continuously outputs airflow downward, so that two upper and lower airflows are generated in the drying box 1, so that the down can move in the drying box 1, and then get uniform drying. In addition, when the hot air stops being input, the fan blades 10 gradually rotate downwards under their own weight until they stop rotating, and the rotating shaft 7 also stops rotating accordingly. At this time, the mobile fan 8 also gradually descends under its own weight, and the surface of the rotating shaft 7 is cleaned during the descent process, thereby reducing the adhesion loss of down. At the same time, the mobile fan 8 can drive the floating down to move downwards during the descent process, thereby reducing the waiting time required for collecting the down.

[0028] When the fan blades 10 stop rotating, they enter the mounting grooves 11. The down does not contact the fan blades 10 during the falling process. The down that falls to the top of the base 9 slides directly on the top of the base 9, reducing the adhesion of the down.

[0029] As a further solution of the present invention, the rotating shaft 7 is a hollow structure, and a brake block 12 is provided at the top of the rotating shaft 7 for driving the rotating shaft 7 to stop suddenly. A reset spring 13 is provided between the brake block 12 and the rotating shaft 7, and a connecting rope 14 is provided between the fan blade 10 and the brake block 12, which passes through the cavity of the rotating shaft 7 and is used to drive the brake block 12 to move.

[0030] In the above embodiment, the slow stopping process of the fan blade 10 causes the down to adhere to the fan blade 10, affecting the collection efficiency of the down. By providing the brake block 12, the fan blade 10 gradually rotates downward after the hot air stops being input, so that the tension of the connecting rope 14 on the brake block 12 is weakened, and the brake block 12 moves upward under the action of the reset spring 13. When the brake block 12 contacts the mounting seat 6, the rotating shaft 7 stops rotating immediately, and the fan blade 10 also stops rotating immediately. The fan blade 10 rotates downward rapidly under its own gravity until it enters the mounting groove 11. The down will not contact the fan blade 10 during the falling process to cause adhesion, which is helpful for the collection of the down.

[0031] As a further solution of the present invention, an air bag 15 capable of restoring its own shape is provided at the bottom of the mobile fan 8 , and the air bag 15 is provided with more than two air holes for blowing away the down on the surface of the base 9 .

[0032] As a further solution of the present invention, the airbag 15 is annular and sleeved on the rotating shaft 7, and the air holes on the airbag 15 are arranged obliquely downward.

[0033] In the above embodiment, when the mobile fan 8 moves downward, it contacts the base 9, so that the airbag 15 is squeezed, thereby squeezing out the air in the airbag 15. The air in the airbag 15 blows away the down adhering to the top of the base 9 and the mobile fan 8 during the outward ejection process, and blows away the down cleaned on the surface of the rotating shaft 7 during the movement of the mobile fan 8, thereby preventing the mobile fan 8 from clamping a certain amount of down when contacting the base 9, and further improving the down collection efficiency.

[0034] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
