The independent pocket spring is compressible and resilient; wherein the independent pocket spring has an air inlet valve and an air outlet valve provided thereon; an air outlet tube is connected to the air outlet valve of the independent pocket spring and the air inlet valve of an adjacent independent pocket spring, and an air inlet tube is connected to the air inlet valve of the independent pocket spring and the air outlet valve of an adjacent independent pocket spring.

Claims

1. An air cushion type independent pocket spring structure, comprising a top cushion, a lower cushion and a plurality of independent pocket springs, wherein, the top cushion and the lower cushion are respectively located in a top portion and a bottom portion of the independent pocket spring, and the plurality of independent pocket springs are distributed on a base; the independent pocket springs are compressible and resilient pocket springs; wherein the top cushion and the lower cushion are made of a flat and non-deformable material; the independent pocket spring has an air inlet valve and an air outlet valve disposed on a periphery of a bottom thereof, an air outlet tube is connected to the air outlet valve of the independent pocket spring and the air inlet valve of the adjacent independent pocket spring, and an air inlet tube is connected to the air inlet valve of the independent pocket spring and the air outlet valve of the adjacent independent pocket spring; accordingly, air from the compressed independent pocket spring is introduced into the adjacent independent pocket spring instead of flowing into the uncompressed independent pocket spring to enable the independent pocket springs in a compressed area to have adequate flexibility without collapsing completely.

2. The air cushion type independent pocket spring structure of claim 1, wherein the independent pocket spring is a pocket spring having a serrated periphery.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] An air cushion type independent pocket spring structure according to the present invention, as shown in FIGS. 1, 2, 3, 4 and 5. An independent pocket spring 20 is mainly comprised of a top cushion 21, a lower cushion 22 and a base 30. A plurality of independent pocket springs 20 are placed on the base 30, and the top cushion 21 and the lower cushion 22 are respectively located in a top portion and a bottom portion of each of the independent pocket springs 20; each of the independent pocket springs 20 is a pocket spring having a serrated periphery and may be a compressible and resilient pocket spring made of a soft material. The top cushion 21 and the lower cushion 22 are flat and made of a non-deformable material, and is generally made of a slightly tougher material; each of the independent pocket springs 20 has an air inlet valve 23 and an air outlet valve 24 disposed on a periphery of a bottom thereof, and the air outlet valve 24 of the independent pocket spring 20 has an air outlet tube 241 connectingly provided thereon, the air outlet tube 241 is further connected to the air inlet valve 23 of an adjacent independent pocket spring 20; the air inlet valve 23 of the independent pocket spring 20 has an air inlet tube 231 communicated thereto, and the air inlet tube 231 is further connected to the air outlet valve 24 of an adjacent independent pocket spring 20 (as shown in FIGS. 4 and 5, the reversed V indicates the independent pocket spring 20 is rising, and V indicates the independent pocket spring 20 is dropping).

[0017] By using the aforesaid improved structure, the present invention provides an air cushion type independent pocket spring structure in which the independent pocket spring 20 can be used as a bed, a head pillow, a slumber pillow, a throw pillow, a bed pillow, a seat cushion and a car pillow; in addition to household uses, the present invention can also be used in cars. During use, the independent pocket spring 20 is pressed downwards by the weight of the body of a person (as shown in FIG. 5), in which a part of the independent pocket springs 20 are compressed, and air therein is discharged into an adjacent independent pocket spring 20 via the air outlet valve 24 instead of being discharged into uncompressed independent pocket springs 20; when the independent pocket springs 20 are not pressed downwards by the weight of the body of the person, that is, when the person rolls over or is not pressing on the independent pocket springs 20, the independent pocket springs 20 return to an original shape naturally, and air from the compressed independent pocket springs 20 is introduced into the adjacent independent pocket springs 20 instead of flowing into the uncompressed independent pocket springs 20, so as to enable the independent pocket springs 20 in a compressed area to have adequate flexibility without collapsing completely.

[0018] When each of the independent pocket springs 20 is compressed, the top cushion 21 and the lower cushion 22 have a force exerted thereon respectively, and the force is also exerted on the independent pocket spring 20. Because the top cushion 21 and the lower cushion 22 are both flat and made of a non-deformable material, the top cushion 21 slowly rises without deformation when not compressed or under an air pressure of other independent pocket springs 20, whereas the top cushion 21 slow drops without deformation when air exits from the independent pocket spring 20, such that when the body of the person contacts and presses on a plurality of independent pocket springs 20, the independent pocket springs 20 still have adequate flexibility without collapsing completely; a balance is achieved between the independent pocket springs 20, so that the occurrence of having the independent pocket springs 20 in a part of areas over-tilted due to compression can be avoided, and the issue of having the independent pocket springs 20 in an uncompressed area protruded excessively can be eliminated. The air cushion type independent pocket spring structure does not cause clear disparity in the tilting between the compressed and the uncompressed areas, which is an improvement over the prior application and is more applicable.

[0019] Similar to the prior application, the invention of the present application can also have multiple layers added to a bottom portion thereof for filtering air (a filter body, an activated carbon material, a fragrance), and the filter body and the activated carbon material used for filtering the impurities in the air can be various types of filter materials (such as bamboo charcoals), and then a fragrance is applied to disseminate a pleasant smell, thus enabling a person to be associated with the natural environment, so as to make the person feel refreshed and pleased.

[0020] Further, the compression and returning to an original shape for all of the independent pocket springs 20 are achieved by utilizing natural movements resulted from the weight of a person and rolling over of the person without requiring additional forces. When pressed by the weight of a person, internal air in an independent pocket spring 20 serially flows between the other independent pocket springs 20; moreover, the independent pocket spring 20 can be mounted with a sensor and combined with a modern electronic transmission mode, such that a duration and intervals of a sleep time of a person can be transmitted to an electronic device such as a mobile phone after being sensed, in order to record the sleep time to serve as a basis for reference.

[0021] It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.

[0022] In summary, the present invention provides an air cushion type independent pocket spring structure having novelty, applicability and non-obviousness which are beyond doubt and satisfying the requirements for patent application, and thus an application has been filed accordingly.
