Description
TECHNICAL FIELD
[0001] The present application relates to the field of down filling equipment, in particular to a light and thin down quilt and a down filling structure thereof. BACKGROUND
[0002] In order to realize the core function of preventing down from escaping (run-off), the light and thin down quilt usually adopts high-count and high-density fabric or fabric treated by coating / film covering. Although this kind of fabric effectively solves the problem of down escaping, its inherent low air permeability or almost no air permeability has a significant negative impact on the down filling process. When the down is filled into the closed cavity of the quilt shell through the down filling device, a large amount of air is brought in. Due to the poor air permeability of the fabric, the air cannot be discharged smoothly and in time, but is retained in each filling cavity. As a result, the down clumps entering the cavity are surrounded and buffered by the surrounding retained air, and cannot freely and fully spread and stretch in the cavity. The presence of air resistance makes the down more likely to accumulate near the down filling port or to move disorderly in the cavity, and it is difficult to be evenly distributed to each corner of the cavity, which easily forms "lumps" and "gaps" with too much or too little down, affects the quality of down filling, and requires manual patting and shaking to assist air discharge and down distribution, thereby reducing the production efficiency.

[0017] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0018] Example 1 Please see Figure 1 A lightweight down comforter includes: a down comforter body 1, the down comforter body 1 comprising a plurality of filling cavities 101 (the down comforter body 1 is divided into a plurality of filling cavities 101), and a down filling opening 102 (e.g., a down filling port 102) on one side wall of the down comforter body 1. Figure 1 As shown, the down filling port 102 is located on the left side of the down comforter body 1. There are several down filling ports 102, and one down filling port 102 corresponds to a row of filling cavities 101 (as shown). Figure 1 For example, the main body 1 of the down comforter of this application has four rows), and the horizontally adjacent filling cavities 101 are connected by a connecting port 103. The filling port 102 in the same row is on the same horizontal line as the connecting port 103. An exhaust port 104 is provided on the filling cavity 101. The exhaust port 104 of the second row of filling cavities 101 is connected to the first row of filling cavities 101, and the exhaust port 104 of the third row of filling cavities 101 is connected to the fourth row of filling cavities 101 (two adjacent filling cavities 101 are connected by an exhaust port 104). The exhaust ports of the first row and the fourth row of filling cavities 101 are connected to the outside.
[0019] It should be noted that when the hedge duvet body 1 is filled, the filling tube 3 of the filling device is inserted into the second or third row of filling cavities 101 corresponding to the filling port 102, and then the filling is started. After filling one filling cavity 101, the duvet body 1 is moved to the right, so that the filling tube fills several filling cavities 101 in the row at a time; during filling of the middle filling cavities 101, the gas in the filling cavity 101 enters the inner cavity of the outer filling cavity 101 through the exhaust port 104; after the filling cavities 101 in the second and third rows are filled, the above operation is repeated to fill the filling cavities 101 in the first or fourth row in turn. During the filling process, the gas in the outer filling cavity 101 is discharged to the outside through the exhaust port 104, and after the filling is completed, the exhaust port 104 and the filling port 102 on the outside are sealed.
[0020] Embodiment 2 As a further optimized solution of Embodiment 1, please refer to Figure 2 and Figure 3 A filling structure, comprising: a filling device body 2, the filling device body 2 is provided with a filling tube 3, and the outer wall of the filling tube 3 is provided with a support assembly 4; when the filling tube 3 is inserted into the filling port 102, the support assembly 4 expands the filling port 102, which can effectively support and expand the fabric around the filling port 102 from the inside, prevent it from collapsing and closing due to softness or pressure of the fabric, and establish and maintain a stable physical channel, so that the gas in the filling cavity 101 can be discharged, ensuring that the filling process is not affected. This supporting effect ensures that the gas in the filling cavity 101 can be discharged along the expanded filling port 102 area, greatly improving the stability and reliability of the exhaust efficiency, making the gas discharge process more smooth and controllable. This design reduces the dependence on manual auxiliary exhaust (such as beating) in the filling operation, making the entire filling process more standardized and automated.
[0021] In this embodiment, as a further optimized solution, please refer to Figure 3 and Figure 4The support assembly 4 includes a kit 401, several support bars 403, and a drive component (such as an electric telescopic rod). The kit 401 is fitted onto the outer wall of the down filling tube 3. Several support bars 403 are arranged in a ring on the outer side of the kit 401. A movable block 406 is provided on the side wall of the support bar 403 facing the kit 401. Several mounting slots 405 are provided on the outer wall of the kit 401 (the number of mounting slots 405 corresponds one-to-one with the number of movable blocks 406). The movable blocks 406 are slidably mounted on the kit 401. Inside the mounting slot 405, the driving component is located. A filter 404 (circular in shape) is provided between several support bars 403 and the kit 401 to intercept down feathers. The driving component drives the moving block 406 to move outward from the mounting slot 405, so that the support bars 403 are away from the kit 401. The support bars 403 open the down filling port 102. The gap between the support bars 403 and the kit 401 can be used to release the gas inside the filling cavity 101.
[0022] In this embodiment, as a further optimization, please refer to... Figure 3 , Figure 4 and Figure 5 The support bar 403 includes two mounting blocks 4031 and an elastic block 4032 (made of rubber). The mounting blocks 4031 are hinged to the movable block 406. Each of the two mounting blocks 4031 has a receiving groove 4034 at one end close to the other. The elastic block 4032 has movable blocks 4035 at both ends. The movable blocks 4035 slide into the inner cavity of the receiving groove 4034 (the inner wall of the receiving groove 4034 is tightly fitted to the outer wall of the movable block 4035 to prevent gas leakage inside the receiving groove 4034). The receiving grooves 4034 are connected by a connecting pipe 408, and one of the receiving grooves 4034 is connected to an external air pump. Air is injected into the receiving grooves 4034 and guided through the connecting pipe 408, ensuring that all receiving grooves 4034 are filled with air, which pushes the movable blocks 4035 to move outward from the receiving grooves 4034. This causes the elastic block 4032 to bend and bulge outwards (the elastic block 4032 is concave on the side away from the kit 401), increasing the area where the support strip 403 expands the filling port. This further ensures that the gas inside the filling cavity 101 can be discharged. It can quickly and actively remove the air injected with the down and retained in the filling cavity, fundamentally eliminating the "air resistance effect". As the air pressure inside the filling cavity 101 is rapidly released through the exhaust port, the down clumps lose the restraint of the air buffer and can freely and fully diffuse, expand and fluff in the cavity, ensuring the immediate performance of its fluffy performance. It effectively avoids down accumulation or uneven distribution caused by airflow turbulence, allowing the down to be evenly filled to all corners of the cavity at one time, significantly improving the consistency and efficiency of filling, and laying the foundation for the finished product to obtain a flat appearance and balanced warmth.
[0023] In this embodiment, as a further optimization, please refer to...Figure 5 The inner side wall of the elastic block 4032 is provided with a groove 4033, which facilitates the outward bending of the elastic block 4032, reduces the bending resistance of the elastic block 4032, and prolongs the service life of the elastic block 4032.
[0024] In this embodiment, as a further optimized scheme, please refer to Figure 3 and Figure 6 The sleeve 401 is sleeved on the outer wall of the filling tube 3, and the support strip 403 is provided with a clamping member 407 (such as a clamp). The clamping member 407 is clamped on the duvet body 1, so that when the duvet body 1 moves on the filling tube 3, the support assembly 4 slides on the outer wall of the filling tube 3, ensures that the support assembly 4 is always located in the filling opening 102, and ensures that the support assembly 4 supports the filling opening 102 and does not lose the effect.
[0025] In this embodiment, as a further optimized scheme, please refer to Figure 3 The end of the sleeve 401 is provided with a plurality of through holes 402; the gas inside the filling cavity 101 can be discharged through the through holes 402, the way of discharging the gas inside the filling cavity 101 by the support assembly 4 is increased, a high-efficiency and stable dynamic exhaust system is constructed, the rapid and sufficient fluffing and uniform distribution of the down are ensured, and thus the warmth-keeping performance, appearance quality and production consistency of the product are directly improved, and the reliability and efficiency of the production process are also enhanced.
[0026] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
