Description

Technical Field

[0001] The utility model relates to the technical field of bedding products, in particular to a silent and oil-proof cover, an elastic support module and a mattress. Background Art

[0002] In recent years, many mattresses have resin ball modules as support parts to improve the sleeping comfort of users. However, the top surface of the resin ball module needs to be coated with lubricating oil. In order to prevent the lubricating oil from contacting other parts of the mattress (such as the latex layer or spring layer, etc.), the resin ball module is usually installed in a TPU oil-proof sleeve (TPU, thermoplastic polyurethane elastomer, is a material with excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance).

[0003] During actual use, it was found that although the TPU oil-proof cover can achieve a good anti-oil seepage effect, the TPU material is prone to make abnormal noise when rubbed. The TPU oil-proof cover is made entirely of TPU material, and the amount of TPU material used is large. The large amount of TPU material causes the TPU oil-proof cover to make obvious abnormal noise even if the user slightly moves and squeezes the TPU oil-proof cover on the mattress.

[0004] Therefore, it is necessary to improve the existing mattress to solve the problem that it is easy to make abnormal noise.

[0005] The above information disclosed in this Background section is included only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not form the prior art that is currently known to a person of ordinary skill in the art. Utility Model Content

[0010] The edges of the oil-proof layer and the sound-absorbing layer are connected and surround each other to form an inner space;

[0011] Moreover, under the same stress environment, the friction noise generated by both the sound-absorbing layer and the coated fabric is smaller than the friction noise generated by the oil-proof film.

[0012] Optionally, the oil-proof film is a TPU film, a FKM film or a PEEK film.

[0016] Optionally, a sealing zipper is provided at the opening of the oil-proof sleeve.

[0017] Optionally, the edges of the oil-proof film and the coated fabric are fixed by sewing, heat sealing, or ultrasonic welding.

[0018] On the other hand, an elastic support module is provided, comprising a resin ball module and any one of the silent and oil-proof sleeves sleeved outside the resin ball module.

[0019] Optionally, the resin ball module includes a resin ball bottom plate and a plurality of resin ball bodies located on top of the resin ball bottom plate.

[0020] In another aspect, a mattress is provided, comprising a top fabric layer, a bottom fabric layer, and a plurality of intermediate layers between the top fabric layer and the bottom fabric layer;

[0021] Wherein, at least one of the intermediate layers is the elastic support module.

[0038] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0039] The utility model provides a silent oil-proof sleeve, an elastic support module and a mattress, which are suitable for application scenarios of providing sleep support for a human body, and can effectively solve the problem that the existing mattress is prone to abnormal noise.

[0040] See also Figure 1 The mattress provided in this embodiment includes a top fabric layer 100, a bottom fabric layer 200, and a plurality of intermediate layers located between the top fabric layer 100 and the bottom fabric layer 200; wherein, at least one of the intermediate layers is an elastic support module 300a, and the remaining intermediate layers may be a latex layer 300b, a 3D cotton layer or a spring layer, etc.

[0041] The elastic support module 300a includes a resin ball module 1 and a silent oil-proof sleeve 2 sleeved on the outside of the resin ball module 1. Specifically, the resin ball module 1 includes a resin ball bottom plate 101 and a plurality of resin ball bodies 102 located on the top of the resin ball bottom plate 101, wherein the top of the resin ball body 102 is coated with lubricating oil.

[0042] In this embodiment, the silent oil-proof sleeve 2 includes an oil-proof layer 201 and a sound-absorbing layer 202. The oil-proof layer 201 includes an oil-proof film 2011 and a coated fabric 2012 located on one side of the oil-proof film 2011. Optionally, the edges of the oil-proof film 2011 and the coated fabric 2012 are sewn, heat-sealed, or ultrasonically welded to prevent the oil-proof film 2011 and the coated fabric from separating from each other.

[0043] The sound-absorbing layer 202 is located on the side of the oil-proof film 2011 away from the coated fabric 2012. Optionally, the oil-proof layer 201 as a whole forms a box-like structure with the opening facing downward. The sound-absorbing layer 202 is located at the opening of the box-like structure, and the edges of the three sides (two short sides and one long side) of the oil-proof layer 201 and the sound-absorbing layer 202 are sewn, heat-sealed, or ultrasonically welded, so that the oil-proof layer 201 and the sound-absorbing layer 202 surround and form a sleeve space sufficient to accommodate the resin ball module 1.

[0044] The fourth side (the other long side) of the oil-proof layer 201 and the sound-absorbing layer 202 is reserved with an oil-proof sleeve opening that connects the inner space of the sleeve to the outer space of the silent oil-proof sleeve 2, and the oil-proof sleeve opening is provided with a sealing zipper 203. After opening the sealing zipper 203, the resin ball module 1 can be inserted into the silent oil-proof sleeve 2 through the oil-proof sleeve opening, and then the sealing zipper 203 is closed to prevent oil from seeping into the outside of the silent oil-proof sleeve 2.

[0045] The silent oil-proof sleeve 2 provided in this embodiment, under the same stress environment, the friction noise generated by both the silencing layer 202 and the coated fabric 2012 is smaller than the friction noise generated by the oil-proof film 211, for example:

[0046] ① The oil-proof film 2011 is a thin film with excellent oil-proof performance such as a TPU film, a FKM film (fluororubber film) or a PEEK film (polyetheretherketone film);

[0047] ② The coated fabric 2012 may be a waterproof canvas or non-woven fabric that is not likely to make noise after being rubbed; further, the coated fabric 2012 is preferably a waterproof fabric to enhance the oil-proof performance;

[0048] ③ The sound-absorbing layer 202 is preferably made of flannel, blanket, sound-absorbing cotton or foam cloth with excellent sound-absorbing performance.

[0049] After extensive research, it was found that the friction noise of TPU material is relatively large, so even if the user moves slightly on the mattress, the TPU anti-oil cover will make unusual noises due to friction.

[0050] Specifically, friction noise refers to the sound produced during the friction process, usually caused by the interaction and relative motion between two contacting surfaces. When objects rub against each other, surface irregularities (such as roughness) cause tiny collisions and vibrations, which are transmitted in the form of sound waves and are perceived by the human ear as noise.

[0051] As an optional method for evaluating the level of friction noise, you can use a variety of materials to make test samples of the same size, and then under the same temperature and humidity conditions, use the same method and strength to rub each test sample in turn, and while rubbing, obtain the noise volume caused by the rubbing. By sorting each test sample according to the size of the noise volume, you can sort the friction noise of multiple materials.

[0052] In the silent oil-proof sleeve 2 provided in this embodiment, under the same stress environment, the friction noise generated by both the silencing layer 202 and the coated fabric 2012 is smaller than the friction noise generated by the oil-proof film 2011. For example, under the same environmental conditions such as temperature and humidity, when the magnitude and direction of the friction force are the same, the noise generated by the mutual friction between the silencing layer 202 and other intermediate layers is smaller than the noise generated by the mutual friction between the oil-proof film 2011 and other intermediate layers, and the noise generated by the mutual friction between the coated fabric 2012 and other intermediate layers is smaller than the noise generated by the mutual friction between the oil-proof film 2011 and other intermediate layers.

[0053] On the one hand, a coating fabric 2012 is pasted on the top of the oil-proof film 2011 to prevent the oil-proof film 2011 from directly contacting with other components with large friction noise such as latex in the mattress, thereby reducing the friction noise generated by the oil-proof film 2011;

[0054] On the other hand, the lower part of the silent oil-proof sleeve 2 is made of the sound-absorbing layer 202 , which greatly reduces the amount of the oil-proof film 2011 and further reduces the friction noise generated by the oil-proof film 2011 .

[0055] Therefore, the silent oil-proof sleeve 2, the elastic support module 300a and the mattress provided by the present invention can effectively solve the problem that the existing mattress is prone to abnormal noise.

[0056] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0057] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the utility model should be included in the protection scope of the utility model.
