[0035] The present invention will be further described below in conjunction with the drawings and specific embodiments of the specification. A person of ordinary skill in the art will be able to implement the present invention based on these descriptions. In addition, the embodiments of the present invention involved in the following description are generally only embodiments of a part of the present invention, rather than all embodiments. Therefore, based on the embodiments in the present invention, all other embodiments obtained by a person of ordinary skill in the art without making any creative work should fall within the scope of protection of the present invention. In addition, the terms "vertical", "horizontal", "front", "rear", etc. mentioned in the embodiments of the present invention indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, or the orientations or positional relationships in which the product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention. It should be further explained that, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" in the description should be understood broadly. For example, "connected" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a direct connection, an indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0036] Example 1:

[0037] like Figures 1-5 As shown, this embodiment provides a fitted sheet unit 01, comprising a covering portion 100 for covering the visible part of the mattress when in use and a back portion 200 connected thereto. The fitted sheet unit 01 also includes a connecting portion 300 for connecting to another fitted sheet unit 01. It should be noted that the connecting portion 300 can be designed to have no width. Figure 1 In order to show the independence of the two fitted sheets except for the connecting portion 300, the width is specifically indicated. In the case of a design without width, the connecting portion 300 actually refers to the seam area of ​​the two fitted sheet units 01.

[0038] The covering portion 100 includes a main surface 110 and two side surfaces 120 connected thereto, an upper side surface 130 and a lower side surface 140. The connecting portion 300 is provided at the connection between the main surface 110 and one of the side surfaces 120. Figure 2 As shown, the side surface 120 of the two side surfaces 120 , which is located on the side corresponding to the connecting portion, is divided into two sections based on the length direction of the connecting portion 300 .

[0039] The back portion 200 is provided with four elastic bands 210 for wrapping the four corners of the mattress and an elastic member 220 for reinforcing the connection with the mattress.

[0040] Understandably, to accommodate split mattresses, no elastic bands are provided in the connection area 300. To ensure uniform force distribution, preferably, two elastic bands 210 are provided at the four corners, forming a symmetrical "Π" shape at the head and foot of the bed. The four elastic bands 210, in concert with the elastic members 220, provide a tight fit, meeting the demands of repeated movements of the electric bed and ensuring the stability and durability of the fitted sheet during operation, thereby ensuring that the mattress maintains excellent support and comfort over time.

[0041] It is understood that the elastic member 220 on each fitted sheet 01 can be one or two. When only one elastic member 220 is provided, the control box and the air pump can be easily avoided; when two elastic members are provided, the tightening effect is better. More specifically, the elastic member 220 is provided as an elastic band (such as Figure 3 as shown) or multi-level connections (as Figure 4The multi-stage button connection setting can effectively avoid the elastic attenuation problem that may occur during long-term use and allow the user to readjust the tightness. The elastic member 220 includes an outer connection point 221 arranged on the side away from the connecting portion 300 and an inner connection point 222 arranged on the side close to the connecting portion 300. Furthermore, the distance between the outer connection point 221 and the upper side 130 is shorter than the distance between the inner connection point 222 and the upper side 130, or the distance between the outer connection point 221 and the lower side 140 is shorter than the distance between the inner connection point 222 and the lower side 140. The outer connection point 221 of the elastic member 220 is biased toward the upper side 130 or the lower side 140 to facilitate installation. If it is biased toward the center position, the fit between the middle part of the mattress and the electric bed will be more secure, but there will be a lack of space for installation operations.

[0042] This embodiment is tested based on the application scenario of the fitted sheet unit 01, and provides the following preferred data: the length range of the main surface 110 is [190cm, 210cm]; the width range of the main surface 110 is [85cm, 95cm]. The length of the connecting portion 300 along the connection direction from the upper side surface 130 to the lower side surface 140 is set to 38cm; the minimum distance between the connecting portion 300 and the lower side surface 140 is set to 87cm. The length range of the elastic member 220 is [40cm, 44cm]; the width range of the elastic member 220 is [2cm, 3cm]. More specifically, you can refer to the following. Figure 5 Size settings shown.

[0043] Example 2:

[0044] This embodiment provides a split fitted sheet, which is based on the fitted sheet unit 01 described in the first embodiment and includes two fitted sheet units 01 . The two fitted sheet units 01 are fixed together by sewing.

[0045] Example 3:

[0046] This embodiment provides an electric bed, using the split fitted sheet as described in the second embodiment.
