[0003] (1) black core cotton heat preservation cotton quilt:
[0004] ①dry black core cotton has poor heat preservation performance.
[0005] ②black core cotton has extremely high water absorption, and almost loses heat preservation performance when meeting water.
[0006] ③black core cotton is prone to elongation and deformation during the winding and unwinding process of the cotton quilt, and the aggregation phenomenon is generated, which affects the overall heat preservation performance of the cotton quilt.
[0007] (2) glueless cotton heat preservation cotton quilt:

[0009] ②the glueless cotton quilt is used for 1-2 years, and due to the winding and unwinding operation, the resilience is reduced, the cotton quilt with a thickness of 60mm is deformed into 20-30mm, almost loses the resilience, and the heat preservation performance is greatly reduced.
[0010] ③the price of the glueless cotton quilt is relatively high.
[0011] Therefore, we propose a pearl wool composite cotton quilt. CONTENT OF THE UTILITY MODEL
[0012] The utility model proposes a pearl wool composite cotton quilt, and solves the problems that the black core cotton quilt has poor heat preservation performance when meeting water and is prone to deformation, and the glueless cotton quilt is prone to deformation and has a relatively high price.
[0013] The technical scheme of the utility model is as follows:
[0014] A pearl wool composite cotton quilt comprises an inner container heat preservation layer and a secondary impermeable layer, and the secondary impermeable layer is fixed to the outer side of the inner container heat preservation layer.
[0015] Preferably, the inner container heat preservation layer is made of pearl wool material.
[0016] Preferably, the secondary impermeable layer is made of film-coated PE cloth material.
[0017] Preferably, the pearl wool composite cotton quilt composed of the inner container heat preservation layer and the secondary impermeable layer adopts a large row spacing sewing process.

[0019] Furthermore, the water injection bag is provided with a water injection port, and a sealing cap is provided at the water injection port.
[0020] The working principle and beneficial effects of this utility model are as follows:
[0021] The pearl cotton composite quilt proposed in this utility model has a reasonable and compact structure and is easy to use. It uses pearl cotton of the required thickness as the inner insulation layer and coated PE cloth as the anti-aging, tensile, and secondary anti-seepage layer. They are sewn together with large spacing from the inside to the outside. It has the advantages of stable product quality, good heat preservation performance, good anti-seepage performance, long service life, recyclability and large-scale industrial production.
[0022] Coated PE fabric has good anti-aging properties, water-proof properties, and tensile strength.

[0033] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0034] Example 1, as Figure 1 As shown in the figure, this embodiment proposes a pearl cotton composite quilt, including an inner insulation layer 1 and a secondary waterproof layer, with a secondary waterproof layer 2 fixed on the outside of the inner insulation layer 1.
[0035] The inner insulation layer 1 is made of pearl cotton. Pearl cotton has good waterproof and heat insulation properties, and it is a flexible insulation material that is easy to roll up. It can be used as the insulation layer of a quilt (the thickness of pearl cotton can be selected according to the required heat insulation performance) to play a heat insulation role. In addition, pearl cotton has good resilience and can remain unchanged, without clumping or thinning after being rolled up and down several times. At the same time, pearl cotton is relatively inexpensive.
[0036] The second layer of waterproofing is made of coated PE fabric. Coated PE fabric has good anti-aging properties, waterproof properties, and tensile strength. Using coated PE fabric for both the inner and outer layers of the quilt can enhance the quilt's anti-aging properties, waterproof properties, and tensile strength, thereby increasing the quilt's service life. Moreover, coated PE fabric is inexpensive.
[0037] The pearl cotton composite quilt, composed of the inner insulation layer 1 and the secondary waterproof layer 2, adopts a large-row-spacing sewing process, which can reduce pinholes, improve insulation performance, simplify processing, and increase production efficiency.
[0038] Example 2, as Figures 1 to 6As shown, this second embodiment further proposes, based on the first embodiment, that traditional greenhouse insulation quilts composed of multiple layers of black-heart cotton and non-adhesive cotton are relatively heavy and require more effort to use. In this embodiment, since the inner lining of the quilt is pearl cotton, which is a lightweight, soft, and elastic material, the pearl cotton composite quilt made of pearl cotton is more labor-saving and easier to operate than traditional greenhouse insulation quilts, whether it is laid out or taken away. However, it also leads to the fact that the lighter material is blown away in windy weather. Therefore, this embodiment has multiple recesses 3 on the pearl cotton composite quilt. A water injection bag 4 can be detachably installed in the recesses 3. The water injection bag 4 is provided with a water injection port, and a sealing cap 5 is provided at the water injection port.
[0039] In this embodiment, the countersunk opening 3 is uniformly opened after the pearl cotton composite quilt is sewn with a large row spacing sewing process. The opening position can be along the edge of the pearl cotton composite quilt. For pearl cotton composite quilts with a large area, several more rows or columns or rows and columns can be opened on the pearl cotton composite quilt in addition to the edge position. After the countersunk opening 3 is opened, the edge position of the countersunk opening 3 needs to be sewn again to make the countersunk opening 3 strong and durable.
[0040] Water filling bag 4 should preferably be made of soft material, with transparent soft material being even better, such as transparent soft plastic material. Transparent material makes it easier for users to see and control the required amount of water.
[0041] Considering the ease of use of the quilt, the detachable method of the water injection bag 4 and the recess 3 should be a quick and inexpensive one. For example, an elastic ring 6 can be sewn into the recess 3, and a corresponding protrusion 7 can be designed on the water injection bag 4. During installation, the elastic ring 6 can be elastically fitted onto the protrusion 7 on the water injection bag 4.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
