Description

Technical Field

[0001] The utility model relates to the technical field of quilt structures, in particular to an inflatable quilt. Background Art

[0002] A quilt is a kind of essential bedding for a family, used to keep people warm while sleeping. At present, a quilt generally includes a quilt cover and a quilt core arranged in the quilt cover, wherein the quilt core is generally a cotton core. Although the cotton core has good thermal insulation function and comfort performance, it is not convenient for storage and transportation due to its large volume and inability to be compressed. At the same time, since the thickness of the cotton core cannot be changed once it is made, its thermal insulation performance cannot be changed either, making it unable to meet the user's use needs in different environments (for example, in winter, users need to use a thick quilt; in summer, users need to use a thin quilt, so a quilt cannot meet the user's use needs in both winter and summer).

[0022] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] The terms "first", "second", "third", "fourth" and the like (if any) in the description and claims of the present invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0024] The directional words such as up, down, left, right, front, back, top, bottom, etc. (if any) involved in the specification and claims of the utility model are defined by the positions of the structures in the drawings and the positions of the structures relative to each other, and are only for the clarity and convenience of expressing the technical solution. It should be understood that the use of directional words should not limit the scope of protection claimed by the utility model.

[0025] like Figures 1 to 4 As shown, the inflatable quilt provided in the embodiment of the utility model comprises a quilt cover 1 and an inflatable quilt core 2 arranged in the quilt cover 1, the quilt cover 1 and the inflatable quilt core 2 are both hollow structures, and an air storage cavity 23 is arranged in the inflatable quilt core 2. An air charging and discharging port 20 is arranged on the inflatable quilt core 2, and the air charging and discharging port 20 is communicated with the air storage cavity 23, and an air charging and discharging valve 3 is arranged at the air charging and discharging port 20, and the air charging and discharging valve 3 is used to inflate the air storage cavity 23 or discharge the gas (generally air) in the air storage cavity 23.

[0026] Specifically, the inflation valve 3 can be connected to an external inflation device (not shown in the figure, the inflation device is, for example, an air pump, an air pump, etc.), and the inflation device is used to inflate the air storage cavity 23 of the inflatable quilt core 2 through the inflation valve 3. When a certain amount of gas is filled into the inflatable quilt core 2, the inflatable quilt core 2 has good thermal insulation performance due to the heat insulation performance of the gas; at the same time, by controlling the amount of gas filled, the thermal insulation performance of the inflatable quilt core 2 can be adjusted (for example, the more gas is filled, the better the thermal insulation performance of the inflatable quilt core 2, and the warmer the inflatable quilt; when it is necessary to weaken the thermal insulation performance of the inflatable quilt, it is only necessary to discharge part of the gas in the air storage cavity 23 through the inflation valve 3). When the inflatable quilt is stored and transported, the gas in the inflatable quilt core 2 is completely (or mostly) discharged through the inflation and deflation valve 3, so that the thickness and volume of the inflatable quilt core 2 are greatly reduced, which can greatly reduce the space occupied by the inflatable quilt, thereby facilitating storage and transportation.

[0027] The inflatable quilt provided in the embodiment of the utility model is provided with an inflatable quilt core 2, and an inflatable and deflated air port 20 and an inflatable and deflated air valve 3 are provided on the inflatable quilt core 2. The inflatable and deflated air valve 3 can be used to inflate or deflate the air storage cavity 23 of the inflatable quilt core 2, thereby adjusting the thickness and thermal insulation performance of the inflatable quilt core 2 to meet the different usage requirements of users and facilitate storage and transportation. At the same time, the inflatable quilt core 2 and the quilt cover 1 cooperate to achieve the effects of double thermal insulation and double air leakage prevention.

[0028] like Figure 3 As shown, as an implementation method, the inflation and deflation valve 3 has both inflation and deflation functions (the structure and function of the inflation and deflation valve 3 can be specifically referred to patents such as CN205278470U or other prior arts). At this time, it is only necessary to set an inflation and deflation port 20 and an inflation and deflation valve 3 on the inflatable quilt core 2 to realize the inflation and deflation functions of the inflatable quilt core 2.

[0029] like Figure 6 As shown, as another embodiment, the inflation and deflation port 20 includes an inflation port 201 and a deflation port 202 respectively arranged at different positions on the inflatable quilt core 2, and the inflation and deflation valve 3 includes an inflation valve 31 arranged at the inflation port 201 and an exhaust valve 32 arranged at the exhaust port 202. Among them, the inflation valve 31 only has an inflation function, and the inflation valve 31 can inflate the inflatable quilt core 2 after connecting the inflation valve 31 to an external inflation device; the exhaust valve 32 only has a deflation function, and when the exhaust valve 32 is opened, the gas in the inflatable quilt core 2 can be discharged through the exhaust valve 32; the inflation and deflation functions of the inflatable quilt core 2 can be realized by the coordination of the inflation valve 31 and the exhaust valve 32.

[0030] like Figure 1 and Figure 2As shown, as an embodiment, the quilt cover 1 includes a first fabric layer 11 and a second fabric layer 12 stacked up and down, and the edge position of the first fabric layer 11 is connected to the edge position of the second fabric layer 12 (specifically, an edge circle of the first fabric layer 11 and an edge circle of the second fabric layer 12 can be connected by sewing or the like), and the inflatable quilt core 2 is located between the first fabric layer 11 and the second fabric layer 12. The inflatable quilt core 2 and the quilt cover 1 are detachable, and an opening 10 is provided at the edge of the quilt cover 1 (the opening 10 can be provided at the edge of one side of the quilt cover 1, the edge of two adjacent sides, the edge of two opposite sides, the edge of three adjacent sides or the edge of four sides, etc.), and the opening 10 is used for the inflatable quilt core 2 to be loaded into or taken out of the quilt cover 1, so that the inflatable quilt core 2 can be inflated and deflated after being taken out of the quilt cover 1, and the quilt cover 1 and / or the inflatable quilt core 2 can be cleaned separately (of course, in other embodiments, the inflatable quilt core 2 and the quilt cover 1 can also be non-detachable, in which case it is necessary to set a hole on the quilt cover 1 at the position corresponding to the inflation and deflation valve 3); a zipper 13 is provided at the opening 10, and the opening 10 can be opened or closed by pulling the zipper 13.

[0031] As an embodiment, a detachable connection structure (not shown) is provided on the quilt cover 1 and / or the inflatable quilt core 2, and the inflatable quilt core 2 and the quilt cover 1 are fixed by the detachable connection structure. The detachable connection structure can be a component such as Velcro, a strap, a snap-on structure, etc., and the inflatable quilt core 2 can be fixed in the quilt cover 1 by the detachable connection structure to prevent the inflatable quilt core 2 and the quilt cover 1 from not fitting well; at the same time, since the inflatable quilt core 2 and the quilt cover 1 are fixed by the detachable connection structure, the inflatable quilt core 2 and the quilt cover 1 are detachable.

[0032] As an embodiment, the inflatable quilt core 2 is made of an airtight material (for example, synthetic fiber fabrics such as polyester and nylon), and an air leakage-proof layer is provided on the inner wall of the inflatable quilt core 2 (not shown in the figure, the air leakage-proof layer can be, for example, a PU coating, a PVC coating, etc.), so that the inflatable quilt core 2 has a good air retention function to prevent air leakage of the inflatable quilt core 2. The quilt cover 1 can be made of soft materials such as cotton, or can be made of an airtight material to further improve the air leakage-proof performance of the inflatable quilt.

[0033] like Figures 2 to 4 As shown, as an embodiment, the inflatable quilt core 2 includes an upper fabric layer 21 and a lower fabric layer 22 stacked up and down, the edge position of the upper fabric layer 21 is connected to the edge position of the lower fabric layer 22 (specifically, an edge circle of the upper fabric layer 21 and an edge circle of the lower fabric layer 22 can be fixed by hot pressing bonding), and an air storage cavity 23 is enclosed between the upper fabric layer 21 and the lower fabric layer 22; the air charging and discharging port 20 and the air charging and discharging valve 3 are arranged on the upper fabric layer 21 and / or the lower fabric layer 22.

[0034] like Figures 2 to 5 As shown, as an embodiment, the air storage cavity 23 includes a plurality of small air chambers 230 separated from each other, and the adjacent small air chambers 230 are interconnected, and the air charging and discharging port 20 is connected to at least one of the small air chambers 230; thus, by inflating and deflation of one of the small air chambers 230, all the small air chambers 230 can be inflated and deflated at the same time. The upper fabric layer 21 and the lower fabric layer 22 are connected up and down at the edge positions of each small air chamber 230, and the upper fabric layer 21 and the lower fabric layer 22 are not connected to each other at the connecting positions of adjacent small air chambers 230, thereby forming an airway 25 between adjacent small air chambers 230, so that adjacent small air chambers 230 are connected through the airway 25 (that is, except for the connecting positions, the upper fabric layer 21 and the lower fabric layer 22 are connected up and down at other positions between adjacent small air chambers 230; in other words, adjacent small air chambers 230 are separated and formed by connecting the upper fabric layer 21 and the lower fabric layer 22). Among them, Figure 2 , Figure 4 and Figure 5 In the figure, the small air chambers 230 are inflated, the surface of the inflatable quilt core 2 corresponding to the positions of the small air chambers 230 is in a bulging state, and the surface of the inflatable quilt core 2 corresponding to the positions between the adjacent small air chambers 230 is in a concave state.

[0035] Specifically, in this embodiment, the air storage cavity 23 is configured as a plurality of small air chambers 230 so that each small air chamber 230 can be evenly inflated, thereby making the inflation amount and thickness at each position of the inflatable quilt core 2 consistent, thereby ensuring the consistency of the thermal insulation performance at each position of the inflatable quilt core 2 and the fit of the inflatable quilt core 2 to the quilt cover 1 (it is easy to understand that if the interior of the inflatable quilt core 2 is an integral large air storage cavity, then after inflation, the inflatable quilt core 2 is likely to be thicker in the middle and thinner in the surroundings (i.e., the middle position is more bulging than the surrounding positions), and thus the thickness consistency and thermal insulation performance consistency at each position of the inflatable quilt core 2 cannot be guaranteed).

[0036] like Figures 2 to 5 As shown, as an embodiment, the upper fabric layer 21 and the lower fabric layer 22 are fixed by hot pressing at the edge of each small air chamber 230, and a composite mark 24 (i.e., a mark formed after hot pressing) is formed at the bonding position of the upper fabric layer 21 and the lower fabric layer 22, and adjacent small air chambers 230 are separated by the composite mark 24 (such as Figure 3 and Figure 5 As shown, since the upper fabric layer 21 and the lower fabric layer 22 are not heat-pressed and laminated at the communicating position of the adjacent small air chambers 230, there is no composite mark 24 at the communicating position).

[0037] like Figures 3 to 5As shown, as an embodiment, a plurality of small air chambers 230 are distributed in an array on the inflatable quilt core 2. Specifically, in this embodiment, the inflatable quilt core 2 is a rectangular structure, the inflatable quilt core 2 has a length direction L and a width direction W, and a plurality of small air chambers 230 are distributed in an array along the length direction L and the width direction W on the inflatable quilt core 2. At the same time, the small air chambers 230 are rectangular structures (such as Figure 3 As shown, a small air chamber 230 is defined between every four adjacent composite marks 24, and at least the four vertex positions of some of the small air chambers 230 are connected with the adjacent small air chambers 230 (i.e., the air passages 25 are formed at the four vertex positions of the small air chambers 230). Of course, in other embodiments, the inflatable quilt core 2 can also be in other shapes, such as a circle, etc.; the small air chamber 230 can also be in other shapes, such as a circle, etc.

[0038] like Figures 3 to 5 As shown, as an embodiment, a plurality of small air chambers 230 cover the entire inflatable quilt core 2, that is, each position of the inflatable quilt core 2 can be inflated and deflated at the same time, and only one set of inflation and deflation ports 20 and inflation and deflation valves 3 may be provided.

[0039] like Figure 7 As shown, as another embodiment, the inflatable quilt core 2 includes a first area portion 2A and a second area portion 2B, the first area portion 2A is an annular structure, the first area portion 2A is arranged around the edge of the inflatable quilt core 2, and the second area portion 2B is located on the inner side of the first area portion 2A (that is, the second area portion 2B is located on the side of the first area portion 2A close to the center of the inflatable quilt core 2; that is, the second area portion 2B is located within the range defined by the first area portion 2A). The air storage cavity 23 in the first area portion 2A and the air storage cavity 23 in the second area portion 2B are separated from each other independently and are not connected to each other, and the first area portion 2A and the second area portion 2B are respectively provided with a charging and discharging port 20 and a charging and discharging valve 3, so that the air storage cavity 23 in the first area portion 2A and the air storage cavity 23 in the second area portion 2B can be charged and discharged separately. Such a configuration allows the first area 2A to be filled with less gas than the second area 2B, so that the thickness of the first area 2A is slightly thinner and will not bulge, and the inflatable quilt core 2 and the quilt cover 1 fit better (the quilt cover 1 is thinner around the periphery than in the middle). In this embodiment, the air storage cavity 23 in the first area 2A is separated from the air storage cavity 23 in the second area 2B by a composite mark 24 (that is, the upper fabric layer 21 and the lower fabric layer 22 are fixed by hot pressing at the junction of the first area 2A and the second area 2B).

[0040] At the same time, the air storage chamber 23 in the second area portion 2B can be set in the form of multiple small air chambers 230, and the air storage chamber 23 in the first area portion 2A can be set in the form of an integral large annular air storage chamber, or can be set in the form of multiple small air chambers 230.

[0041] The inflatable quilt provided in the embodiment of the utility model is provided with an inflatable quilt core 2, and an inflatable and deflated air port 20 and an inflatable and deflated air valve 3 are provided on the inflatable quilt core 2. The inflatable and deflated air valve 3 can be used to inflate or deflate the air storage cavity 23 of the inflatable quilt core 2, thereby adjusting the thickness and thermal insulation performance of the inflatable quilt core 2 to meet the different usage requirements of users and facilitate storage and transportation. At the same time, the inflatable quilt core 2 and the quilt cover 1 cooperate to achieve the effects of double thermal insulation and double air leakage prevention.

[0042] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
