Description
SANDWICH-TYPE POCKETED SPRING UNIT AND POCKETED
SPRING
TECHNICAL FIELD
The present disclosure relates to the technical field of pocketed springs, and in particular to a sandwich-type pocketed spring unit and a pocketed spring.
BACKGROUND
In an existing pocketed-spring mattress, cloth, sponge, latex and the like are generally wrapped outside the mattress to improve the comfort of the mattress. Since the mattress is wrapped with an outer fabric or sponge, an inner space of the mattress is relatively closed, and thus the interior of the mattress is susceptible to growth of bacteria and mites after moist air enters the inner space of the mattress. In the prior art, in order to solve this technical problem, a dry filler is often added inside the mattress to prevent the growth of bacteria and mites.
Furthermore, in the prior art other fillers such as functional fragrances are also often added inside the mattress to increase the functionality of the mattress. However, since the inner space of the pocketed-spring mattress is narrow and small and is lack of a necessary filler supporting carrier, it is difficult to effectively fix the filler and uniformly arrange the filler.
SUMMARY
According to the present disclosure, there is provided with a structurally robust sandwich-type pocketed spring unit and a pocket spring.
According to one aspect of the present disclosure: a sandwich-type pocket spring unit, comprising: at least two accommodating chambers formed of cloth, divided into an upper accommodating chamber and a lower accommodating chamber; and a spring body encapsulated and packaged inside each accommodating chamber; a sandwiched chamber formed between the upper accommodating chamber and the lower accommodating chamber, wherein a functional filler is disposed inside the sandwiched chamber.
According to another aspect of the present disclosure: a sandwich-type pocket spring unit, comprising: at least two accommodating chambers formed of cloth, divided into an upper accommodating chamber and a lower accommodating chamber; and a spring body encapsulated and packaged inside each accommodating chamber; a sandwiched chamber formed between the upper accommodating chamber and the lower accommodating chamber, wherein the sandwiched chamber is formed as an airbag or is provided inside with an elastic filler.
According to a further aspect of the present disclosure: a sandwich-type pocketed spring, comprising multiple sandwich-type pocketed spring units of the one aspect or the another aspect sequentially connected with one another.
Advantageously, the sandwiched chambers between adjacent sandwich-type pocketed spring units are sequentially connected, and each of the sandwiched chambers has a curved shape with a continuous profile.
Beneficial technical effects: for this sandwich-type pocketed spring unit and pocketed spring, by additionally disposing one layer of sandwiched chamber between the upper and lower layers of pocketed springs, different fillers can be filled and placed inside the sandwiched chamber according to actual needs to achieve different effects, and the fillers are orderly and uniformly distributed inside the mattress through respective sandwiched chambers, thereby overcoming the defect of a traditional mattress that the filler is scattered and disordered.

BRIEF DESCRIPTION OF THE DRAWINGS
The present disclosure will be further described below in connection with the accompanying drawings and embodiments;
Fig. 1 is a schematic structural view of an embodiment of a sandwich-type pocketed spring unit of the present disclosure;
Fig. 2 is a schematic structural view of an embodiment of a sandwich-type pocketed spring of the present disclosure;
Fig. 3 is a schematic structural view of another embodiment of the sandwich-type pocketed spring of the present disclosure; and Fig. 4 is a schematic structural view of further embodiment of the sandwich-type pocketed spring of the present disclosure.
DETAILED DESCRIPTION
Referring to Fig. 1, the present disclosure provides a sandwich-type pocketed spring unit, which includes at least upper and lower layers of accommodating chambers 2 formed by cloth 1, and a spring body 3 respectively encapsulated and packaged in respective accommodating chamber 2. The cloth 1 is folded into an inverted U shape, and is divided into multiple chambers from top to bottom through multiple transverse welds. In this embodiment, three layers of chambers are formed, and the upper and lower layers of accommodating chambers
2 respectively package and encapsulate the spring body 3. The chambers between the upper and lower layers of accommodating chambers are sandwiched chambers 4, and different fillers can be filled and placed inside the sandwiched chambers 4 according to actual needs to achieve different effects.
For example, a desiccant can be placed into the chambers to achieve mildew proof and moisture proof effects; activated carbon can be placed into the chambers to eliminate odor; a magnet can be placed into the chambers to increase the biological effects of magnetic fields and promote blood circulation, thereby improving the function of a human body; other functional fillers such as hygienical fragrances, insecticides, mothproofing agents and flame retardants can also be placed into the chambers to achieve corresponding functional effects; and of course, multiple fillers also can be mixed to achieve a mixture of multiple functions.
An elastic filler such as sponge may also be placed inside the sandwiched chamber 4, or a cushion airbag formed by cloth with better gas tightness may also be provided as the sandwiched chamber 4, according to needs, such that a soft elastic layer is formed in the sandwiched chamber 4 to increase the cushioning effect of the mattress, and at the same time better separating the adjacent upper and lower spring body 3 to reduce the noise caused by rigid contact and friction between the adjacent upper and lower spring body 3.
Referring to Figs. 2-4, the present disclosure provides a sandwich-type pocketed spring, which includes multiple sandwich-type pocketed spring units sequentially connected with one another, wherein the construction of the sandwiched chamber 4 in the spring unit can be designed into a variety of types, as shown in Fig. 2 or Fig. 3. Preferably, the sandwiched chambers 4 between the adjacent sandwich-type pocketed spring units are sequentially connected and each of them has a curved shape with a continuous profile. That is, the upper and lower layers of accommodating chambers 2 each also has a curved shape with a continuous profile, and the curved shape can be designed according to different physiological curves of a human body and body weights to meet individual needs and thus better fit the physiological curve of the human body while ensuring good support, such that better and more comfort can be provided to a sleeper through a partitioned mattress formed by a string of pocketed springs.
The above detailed description is of the best mode or modes of the disclosure presently contemplated. Such description is not intended to be understood in a limiting sense, but to be an example of the disclosure presented solely for illustration thereof, and by reference to which in connection with the following description and the accompanying drawings one skilled in the art may be advised of the advantages and construction of the disclosure.
