[0002] Slightly scented down products are made by adding fragrance substances or using special processing technology during the production process, so that the products can emit a slight fragrance. In the production process of slightly scented down products, fumigation treatment is a crucial link. This step not only helps to kill bacteria, viruses and parasites in the down, but also effectively removes the odor of the down, improving the hygiene quality of the product and the consumer experience.

[0003] Existing fumigation equipment is difficult to adapt to the fumigation requirements of down products, and it is difficult to realize automated multiple fumigation operations. It is difficult for the fragrance steam to penetrate and diffuse into the interior of the down products. The firmness of the down products is low, resulting in the preparation quality of the slightly fragrant down products being unsatisfactory. In order to improve the fumigation quality of the slightly fragrant down products, the down products need to be fumigated at high temperature for a long time. However, continuous high temperature has an adverse effect on the quality of the down products, causing the down to lose its original elasticity and fluffiness. Long-term high temperature exposure to some down products may also cause fabric aging, discoloration or deformation, etc.; and existing fumigation equipment is difficult to disperse the down clumps of down products, and the fragrance steam is difficult to penetrate into every corner of the down products, so the down products cannot be fully exposed to the fragrance steam.

However, the continuous high temperature has an adverse effect on the quality of down products, causing the down to lose its original elasticity and fluffiness. Please refer to Figure 1-Figure 3 The present invention provides a fumigation treatment device for slightly fragrant down products, comprising a chassis 1, wherein the chassis 1 comprises a placement box 101, a transition box 102 and a fumigation box 103 which are fixed in sequence, wherein the placement box 101 is provided with a plurality of placement chambers 104 which are vertically evenly spaced, wherein the fumigation box 103 is provided with a common fumigation chamber 106, and wherein the transition box 102 is provided with a transition chamber 105 for connecting the fumigation chamber 106 with the placement chamber 104; wherein the placement chamber 104 is provided with a discharge frame 2 for fixing down products, wherein a reset component 4 and a traction component 5 are respectively provided on both sides of the discharge frame 2, wherein the traction component 5 is used to pull the discharge frame 2 into the fumigation chamber 106, wherein the reset component 4 is used to pull the discharge frame 2 back into the placement chamber 104, and wherein a driving mechanism 6 for pulling the traction component 5 is provided on the top of the fumigation box 103.

When the traction assembly 5 is separated from the driving mechanism 6, under the reset force of the first torsion spring 403, the reset wheel 401 drives the first pull rope 404 to reel, and the first pull rope 404 pulls the material discharge frame 2 back into the placement cavity 104, and pulls the traction assembly 5 to the initial position.

[0041] like Figure 6-Figure 8As shown, the traction assembly 5 includes a second pull rope 501; one end of the second pull rope 501 is fixedly connected to the limiting slide rod 3, and the other end extends to the top of the fumigation box 103 and is fixedly provided with a hook 502, and the top of the fumigation box 103 is provided with a vertical plate body 107 for the second pull rope 501 to pass through; the hooks 502 of multiple traction assemblies 5 are vertically evenly distributed on the vertical plate body 107; the hook 502 includes a base 502a and a ring body 502c, and a connecting column 502b is fixedly provided between the base 502a and the ring body 502c.

After the set time, the traction wheel 603 is driven to rotate by the motor 602 again. As the hook rod 604 rotates to the vicinity of the vertical plate body 107, the material discharging frame 2 is restricted and does not move. At this time, the hinged rod body of the hook rod 604 is subjected to a large pulling force and rotates, and the hook 502 is automatically unhooked, thereby completing the entire traction action; the height of the traction wheel 603 and the hook rod 604 is adjusted by the electric push rod 605 to adapt to the hook 502 of the corresponding height, so that the material discharging frames 2 in multiple placement cavities 104 can be pulled.

[0047] S3. Repeat step S2 at least twice to make the fragrance agent firmly adhere to the down product, so as to obtain a down product with a slight fragrance.

[0048] Embodiment 2

[0049] On the basis of the first embodiment, in order to facilitate taking out and placing down products from the placement cavity 104, as shown in FIG. Figure 4-Figure 5 As shown, the discharge frame 2 includes a plurality of hard frames 201, and a flexible connection portion 202 is provided between adjacent hard frames 201, and the flexible connection portion 202 can be specifically set to a rubber block or other flexible material; a plurality of fixing clips 204 for clamping down products are provided on the inner wall of the discharge frame 2, and the length of the fixing clips 204 can be adjusted to adapt to the clamping of down products of different specifications.

[0051] Embodiment 3

[0052] On the basis of the first and second embodiments, in order to further improve the effect of the aroma fumigation, the aroma steam can fully contact with the down products, such as Figure 3 , Figure 9-10 As shown, a flapping mechanism 7 is provided in the transition chamber 105. Figure 3Only one group is shown in the figure, the flapping mechanism 7 includes a plurality of flapping units equidistantly distributed on the upper and lower sides of the down product, the flapping unit includes two second bearing seats 701 and a transmission shaft 702 rotatably arranged between the two second bearing seats 701, the end of the transmission shaft 702 is fixedly sleeved with a toggle piece 703, and when the discharge frame 2 moves, the toggle piece 703 is pushed to drive the entire flapping unit to rotate; a rotating drum 704 is rotatably sleeved on the transmission shaft 702, and a second torsion spring 705 for limiting the rotation of the rotating drum 704 is installed on the transmission shaft 702 at the end of the rotating drum 704, and the second torsion spring 705 is set as a bidirectional torsion spring, and flapping heads 707 are equidistantly arranged on the surface of the rotating drum 704 along its axial direction.

The setting of the toggle member 703 enables the material discharging frame 2 to be beat by the beating mechanism 7 during the reciprocating motion. Then, the rotating drum 704 is driven by an external force, and the rotating drum 704 drives the beating head 707 to rotate. When the external force is removed, under the reset force of the second torsion spring 705, the beating head 707 immediately beats the down product during the reset rotation process, which can disperse the down clumps and make the down fibers more fluffy. During the fumigation process, the fragrance steam can more easily penetrate into every corner inside the down product and fully contact and absorb the fragrance steam.

[0054] In order to make the flapping mechanism 7 more energy-efficient, a gear 706 is fixedly sleeved on the end of the rotating drum 704, and a plurality of racks 203 with equal spacing are fixedly arranged on the material discharging frame 2, and the racks 203 mesh with the gears 706 to drive the rotating drum 704 to rotate. During the movement of the material discharging frame 2, the racks 203 drive the gears 706 to rotate, and the gears 706 drive the rotating drum 704 to rotate. The design of the racks 203 and the gears 706 enables the flapping mechanism 7 to automatically operate based on the movement of the material discharging frame 2, and has better energy-saving performance.

[0055] The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description 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 modifications 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.
