DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0036] In the present application, the terms "upper", "lower", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0037] In addition, in addition to indicating the orientation or positional relationship, the above-mentioned part of the terms can also be used to indicate other meanings, for example, the term "upper" can also be used to indicate a certain dependent relationship or connection relationship in some cases. For those skilled in the art, the specific meaning of these terms in the present application can be understood according to the specific situation.

[0038] In addition, the terms "set", "connected" should be understood broadly. For example, it can be fixedly connected, detachably connected, or integrally constructed; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication between two devices, elements or components. For those skilled in the art, the specific meaning of the above-mentioned terms in the present application can be understood according to the specific situation.

[0039] In addition, the terms "first", "second" and the like are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise stated, the meaning of "multiple" is two or more.

[0040] Bed cover is a protective product used to wrap the mattress, with multiple functions and effects. For example, bed cover can effectively prevent liquids (such as water, beverages, sweat, etc.) and stains (such as dust, dirt, etc.) from directly contacting the mattress, thereby protecting the cleanliness and hygiene of the mattress. At the same time, bed cover can also reduce the friction between the surface of the mattress and the bed sheet, quilt, etc., thereby prolonging the service life of the mattress. In addition, bed cover can also prevent allergens such as dust mites, bacteria and mold from accumulating on the surface of the mattress, helping to improve the sanitary conditions of the sleeping environment.

[0041] Through these effects, bed cover not only protects the mattress, but also improves the comfort and hygiene of the sleeping environment, and is one of the indispensable bedding products in modern home life.

[0042] However, in the daily use of bed cover, bed cover with a single fabric material often cannot meet all the needs of users in different temperatures and seasons. For example, bed covers made of different materials have different comfort levels in different seasons, such as pure cotton bed covers have poor warmth in winter, and polyester bed covers have poor air permeability in summer.

[0043] In addition, the filling inside the bed cover also plays an important role in the user's experience. In winter, functional layers such as warm and fluffy materials can effectively maintain the temperature of the bed cover, providing additional warmth, allowing users to enjoy a warm sleeping environment even in cold seasons. In summer, users often need materials that dissipate heat quickly as the filling inside the bed cover.

[0044] Based on this, the present application discloses a bed cover, a mattress and a bed, which are designed to use multiple different functional layers to fill the accommodation space of the bed cover, thereby meeting the needs of users for multiple sleeping experiences. Specifically, the present application connects the fabric layer and the mattress protection layer through the connecting piece, and the interlayer space formed between the two provides conditions for conveniently replacing the functional layer of the bed cover. Users can replace different functional layers according to different sleeping experience needs to achieve comfortable sleep.

[0045] The technical solutions of the present application will be further described below in conjunction with the embodiments and the drawings.

[0046] Please refer to Figure 1 , Figure 1This is a schematic diagram of the structure of a fitted sheet 1 disclosed in an embodiment of this application. This application discloses a fitted sheet 1 that can be laid on a mattress 2. The mattress 2 may have an upper surface 21 and a side surface 22 connected to the upper surface 21. The fitted sheet 1 includes a mattress protective layer 11, a fabric layer 12, and a functional layer 13. The mattress protective layer 11 includes an upper pad 111 and side panels 112. The upper pad 111 is configured to cover the upper surface 21 of the mattress 2, and the side panels 112 are connected to and surround the outer periphery of the upper pad 111, and are configured to cover the side surface 22 of the mattress 2. The fabric layer 12 is located above the upper pad 111 along the thickness direction of the upper pad 111, and the fabric layer 12 is detachably connected to the upper pad 111 and / or the side panels 112, and the fabric layer 12 and the upper pad 111 form a first interlayer space 121 in the thickness direction of the upper pad 111. Along the thickness direction of the upper pad 111, the functional layer 13 is located in the first interlayer space 121, and the functional layer 13 is stacked between the upper pad 111 and the fabric layer 12.

[0047] The fitted sheet 1 disclosed in this application comprises a mattress protector 11 including an upper mattress body 111 and side panels 112. The side panels 112 surround the outer periphery of the upper mattress body 111, and a fabric layer 12 is detachably connected to the upper mattress body 111, forming a first interlayer space 121 between the fabric layer 12 and the upper mattress body 111. Thus, users can install functional layers 13 with different functions in the first interlayer space 121 according to their actual needs, thereby meeting different sleep requirements. Furthermore, since the fabric layer 12 is detachably connected to the upper mattress body 111, meaning it is essentially a layer that comes into contact with the user, when the fitted sheet 1 needs cleaning, the fabric layer 12 can be removed from the upper mattress body 111 for cleaning. This eliminates the need to remove the entire fitted sheet 1 for cleaning, greatly reducing the cleaning difficulty for the user.

[0048] Please see Figure 2 and Figure 3 , Figure 2 yes Figure 1 A magnified view of a portion of point A in the middle. Figure 3 yes Figure 2 A magnified view of a section at point B.

[0049] In some embodiments, the detachable connection between the fabric layer 12 and the upper mattress 111 may include, but is not limited to, zipper connection, Velcro connection, or strap connection. Using detachable connectors such as Velcro, zippers, or straps allows the fabric layer 12 to be easily removed for washing or replacement, keeping the fitted sheet 1 clean and hygienic. Furthermore, users can quickly replace the fabric layer 12 without replacing the entire fitted sheet 1, saving time on cleaning and maintenance.

[0050] Optionally, the outer periphery of the upper layer 111 is provided with a first connecting member 113, and the fabric layer 12 is provided with a second connecting member 122 corresponding to the first connecting member 113, and the second connecting member 122 is detachably connected with the first connecting member 113. The fabric layer 12 and the upper layer 111 are connected through the detachable connecting member, so that the fabric layer 12 can be conveniently detached for cleaning or replacement, keeping the bed cover 1 clean and sanitary, and the user can quickly replace only the fabric layer 12 without replacing the entire bed cover 1, saving cleaning and maintenance time.

[0051] At the same time, the user can choose different colors, patterns and materials of the fabric layer 12 according to personal preferences, seasonal changes or decoration needs, realizing personalized customization.

[0052] As described above, the first connecting member 113 and the second connecting member 122 can be at least one of Velcro, zipper or strap. For example, the first connecting member 113 and the second connecting member 122 can be both zippers, or the first connecting member 113 and the second connecting member 122 can be both straps. With this detachable connection mode, the connection mode is simple and fast, and the fabric layer 12 is convenient to disassemble and replace.

[0053] In addition, the connection between the fabric layer 12 and the upper layer 111 through the first connecting member 113 and the second connecting member 122 can also ensure the connection reliability of the fabric layer 12 and the upper layer 111, prevent displacement or sliding during use, and keep the bed clean.

[0054] In some embodiments, the first connecting member 113 is located at the edge of the upper surface 21 of the upper layer 111, and when the second connecting member 122 is connected with the first connecting member 113, the fabric layer 12 covers at least part of the first connecting member 113 and the second connecting member 122. In this way, when the first connecting member 113 and the second connecting member 122 are connected, the fabric layer 12 can cover at least part of the first connecting member 113 and the second connecting member 122 when it is sagging, that is, by using the fabric layer 12, the connecting member can be hidden inside the edge of the bed cover 1, so that the appearance of the bed cover 1 is more clean and beautiful.

[0055] In addition, by arranging the connecting member at the edge of the upper surface 21 of the upper layer 111, the user can also avoid accidentally hooking the connecting member during use, improve the safety of using the bed cover 1, and also prevent the connecting member from scratching the surface of the mattress 2.

[0056] Please refer to Figure 4 , Figure 4is a structural schematic diagram of the mattress protection layer 11 of the bed canopy 1 disclosed in the embodiments of the present application. In some embodiments, the upper layer of the cushion body 111 includes a first cover surface 1111, a second cover surface 1112, and a waterproof layer 1114. The second cover surface 1112 is arranged on the first cover surface 1111 in the thickness direction of the upper layer of the cushion body 111, and a second interlayer space 1113 is formed between the first cover surface 1111 and the second cover surface 1112. The waterproof layer 1114 is located in the second interlayer space 1113, and is stacked between the first cover surface 1111 and the second cover surface 1112 in the thickness direction of the upper layer of the cushion body 111.

[0057] By arranging the second interlayer space 1113 inside the upper layer of the cushion body 111, the waterproof layer 1114 can be arranged in the second interlayer space 1113, so that the penetration of liquid (such as water, beverage, sweat, etc.) into the mattress 2 can be effectively avoided, and the cleanliness and dryness of the mattress 2 can be maintained. It can be seen that the waterproof layer 1114 can prevent the mattress 2 from being damp, mildew and breeding bacteria, and prolong the service life of the mattress 2.

[0058] Optionally, the first cover surface 1111 and the second cover surface 1112 can generally adopt soft, breathable and other fabric materials, for example, can be cool fiber, nylon, linen, all-cotton flannelette, coral velvet, flannel and the like, so as to provide users with more comfortable and richer sleep experience.

[0059] In some embodiments, the first cover surface 1111 and the second cover surface 1112 can adopt different materials. Thus, different materials of the fabric can be arranged according to actual needs.

[0060] For example, the first cover surface 1111 can adopt cool fiber material, and the second cover surface 1112 can adopt all-cotton flannelette material, so that users can select cover surfaces of different materials to contact the body according to actual needs. For example, the first cover surface 1111 of cool fiber material is suitable for summer use, and provides a cool touch. The second cover surface 1112 of all-cotton flannelette material is suitable for winter use, and provides a warm touch.

[0061] In some embodiments, the materials of the first cover surface 1111, the second cover surface 1112 and the fabric layer 12 are different from each other. The cover surfaces and the fabric layer 12 of different materials can provide appropriate touch and temperature adjustment according to seasonal changes, and meet the use needs of users in different seasons.

[0062] For example, the fabric layer 12 can be one of bamboo fiber fabric, Tencel fabric, modal fabric and pure cotton fabric.

[0063] The fabric layer 12 is made of breathable, moisture-wicking, antibacterial and anti-mite high-elasticity comfortable fabric. The moisture-wicking function can keep the bed cover 1 dry, avoid discomfort caused by moisture, and provide a soft, elastic and breathable sleep experience.

[0064] In some embodiments, the upper layer 111 and the side wall 112 are made of the same material, and the upper layer 111 and the side wall 112 are configured as an integrated structure. That is, the upper layer 111 and the side wall 112 are an integrated structure, which can prevent the bed cover 1 from moving during use, thereby maintaining the cleanliness and stability of the bed, and ensuring that the bed cover 1 closely fits the mattress 2, providing better support and stability. At the same time, the integrated structure of the upper layer 111 and the side wall 112 can reduce the gap between the splices, reduce the accumulation of dirt and dust, keep the bed cover 1 clean, and simplify the production process and reduce production costs.

[0065] In addition, the upper layer 111 and the side wall 112 made of the same material have the same physical properties (such as elasticity, softness, air permeability, etc.), which can provide uniform performance and improve comfort.

[0066] In some embodiments, the material of the functional layer 13 can be at least one of PCM (Phase Change Material), silicone rubber material, down material, and pure cotton material.

[0067] The functional layer 13 can be set according to different functional requirements. For example, the user can select different materials of the functional layer 13 according to the change of seasons, such as cool material in summer and warm down material in winter, which not only provides different touch and experience and improves the comfort of sleep, but also meets the individual needs of users. In addition, different functional layers 13 can provide antibacterial, anti-mite, warm, heat dissipation and other functions, and users can choose according to actual needs to improve the practicality of the bed cover 1, and users can also choose the appropriate functional layer 13 according to different use scenarios (such as home, hospital, nursing home, etc.) to improve the applicability of the bed cover 1.

[0068] In addition, since the functional layer 13 can be replaced separately, the cost of replacing the bed cover 1 by the user can be reduced.

[0069] Please refer to Figure 5 , Figure 5 is a structural schematic diagram of a bed mattress disclosed in the embodiments of the present application. In some embodiments, the bed mattress 2 can include a bed mattress body 2a and a bed cover 1 as described above. The bed mattress body 2a can include an upper surface 21 and a side surface 22, and the bed cover 1 is wrapped around the upper surface 21 and the side surface 22.

[0070] By covering the bed skirt 1 on the upper surface 21 and the side surface 22 of the mattress body 2a, the mattress 2 can be protected comprehensively. Specifically, the mattress protection layer 11 can effectively prevent liquid and stains from directly contacting the mattress 2, maintain the cleanliness and hygiene of the mattress 2, reduce the friction between the surface of the mattress 2 and the bed sheet, quilt and the like, prolong the service life of the mattress 2, and prevent allergens such as dust mites, bacteria and mold from accumulating on the surface of the mattress 2, which helps to improve the sanitary conditions of the sleeping environment.

[0071] Please refer to Figure 6 , Figure 6 is a structural schematic diagram of a bed disclosed by the embodiments of the present application. In some embodiments, the bed 3 comprises a bed body 3a and the mattress 2 as described above. The mattress 2 can be arranged on the bed body 3a. The user can replace the functional layer 13 of the bed skirt 1 wrapping the mattress 2 on the bed body 3a to obtain different sleep experiences.

[0072] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
