[0052] The first embodiment of the present invention is a piece of cloth, which is divided into upper, middle and lower parts. For beautification purposes, small star patterns are also printed at the junctions of the upper, middle and lower parts. See Figure 1 There is an opening (208) in the middle part, the lower part is a lower skirt (203) (also called a skirt), and there is a slit opening (204) in the upper part, which can be used to put on a plate-shaped cover and pull it down to the root of the plate-shaped cover, so as to play a fixing role (some also have the function of covering the hinge of the plate-shaped cover), and also has the function of restricting the relative displacement between the sheath and the toilet. For the sake of simplicity, in the figure, this piece of cloth is drawn as: folded into a three-dimensional shape when in use, and this piece of cloth is in a flat state when placed on the ground (the following Figure 8 , Figure 11 , Figure 14 , similarly).

[0053] When in use, the slit opening 204 in the upper part is put on the end of the upright root-shaped cover and pulled down to the root of the plate-shaped cover. The middle part (202) of the anti-splash sleeve is laid flat on the flat circular cover and completely covers the circular cover. The through hole (208) in the middle part is located above the circular cover to serve as a channel for excrement to fall. The lower part (203) hangs down to cover the front facade of the toilet, thus separating the front facade of the toilet from the human body and clothes to prevent contact infection. A little can be stuffed into the upper part of the lower part under the circular cover to play a fixing role, which is indicated by a wrinkle (209) in the figure. See Figure 3 , for the sake of simplicity, the small star pattern is not drawn in the figure.

[0054] Figure 3 It is made of a transparent film, Figure 4 It is made of an opaque non-woven fabric.

[0055] The second embodiment of the present invention is a piece of cloth, which is divided into upper, middle and lower parts. For beautification purposes, small star patterns are also printed at the junctions of the upper, middle and lower parts. See Figure 5 . There is an opening (208) in the middle part, the lower part is a lower skirt (203) (also called a skirt), and there is a bag-like structure (205) in the upper part, which can be put on the end of the upright plate-shaped cover (102) in an inverted manner, so as to cover the plate-shaped cover from the end to the root, separate the plate-shaped cover from the back and upper body clothes of the person, play a hygienic anti-contact protection role, and also enable the person sitting on the toilet to lean back and relax the body without worrying about hygiene. It also has the function of restricting the relative displacement between the sheath and the toilet. Thus, it plays a fixing role and also has the function of restricting the relative displacement between the sheath and the toilet. See Figure 6 .

[0056] When in use, the upper bag is put on the end of the vertical plate-shaped cover (102) in an inverted manner. In this way, the upper part (201) of the protective cover covers the plate-shaped cover from the end to the root. The middle part (202) is laid flat on the flat circular cover and completely covers the circular cover. The through hole (208) in the middle part is located above the circular cover and serves as a channel for excrement to fall. The lower part (203) hangs down to cover the front facade of the toilet, thus separating the front facade of the toilet from the human body and clothes to prevent contact infection. A little can be stuffed into the upper part of the lower part under the circular cover to play a fixing role, which is shown by the wrinkle (209) in the figure. Refer to Figure 6 (For the sake of simplicity, the small star pattern is not drawn in the figure.)

[0057] After defecation, the lower part of the protective cover can be pulled by hand to take the protective cover out from under the circular cover. Then (at this time, the bag body (205) is still put on the vertical plate-shaped cover), the middle part and the lower part of the protective cover are straightened, folded in half longitudinally (folded downwards), then twisted into the shape of a rope, and then the upper part (201) is removed and the rope is stuffed into the bag body. (Or first stuff the rope into the gap between the bag body and the plate-shaped cover and then take away the bag body together with the rope). At this time, the bag body becomes a garbage bag, with the function of a garbage bag, making the used protective cover reduce its volume and be sealed to prevent the dirt from polluting the air.

[0058] Figure 7 It is a schematic diagram of the third embodiment of the present invention put on the toilet. The difference between it and the second embodiment is that the shape of the upper bag is triangular on the side and the length of the bag is relatively long, almost equal to the length of the upper part of the protective cover, and can be put on the root of the plate-shaped cover.

[0059] The fourth embodiment of the present invention is a cloth-like object, which is divided into upper, middle and lower parts. For the purpose of beautification, small star patterns are also printed at the junctions of the upper, middle and lower parts.

It also has the function of restricting the relative displacement between the protective cover and the toilet. Thus, it plays a fixing role (some also have the function of covering the hinge of the plate-shaped cover), and also has the function of restricting the relative displacement between the protective cover and the toilet. Refer to Figure 8

[0060] When in use, put the mouth 207 of the cylinder in the upper part (201) into the end of the upright plate-shaped cover (102). In this way, the upper part (201) of the protective cover will completely cover the plate-shaped cover or expose the top of the plate-shaped cover. The middle part (202) is laid flat on the flat circular cover and completely covers the circular cover. The through hole (208) in the middle part is located above the circular cover and serves as a channel for excrement to fall. The lower part (203) hangs down to cover the front facade of the toilet, thus separating the front facade of the toilet from the human body and clothes to prevent contact infection. A little can be stuffed into the lower part near the upper part under the circular cover to play a fixing role, which is indicated by wrinkles (209) in the figure. See Figure 9 , (for the sake of simplicity, the little star pattern is not drawn in the figure).

[0061] After defecation, you can pull the lower part of the protective cover by hand to take the protective cover out from under the circular cover. Then (at this time, the bag body 205 is still sleeved on the upright plate-shaped cover), straighten and twist the middle part and the lower part of the protective cover into a single rope, and then remove the upper part (201) and stuff the rope into the bag body. At this time, the cylinder becomes a garbage bag, with the function of a garbage bag, making the used protective cover reduce its volume and be sealed to prevent the dirt from polluting the air.

The back of the upper part is provided with a T-shaped tie (211). The tie is fixed. Both ends of each tie are fixed to the protective cover body or other ties. It can be put into the end of the upright plate-shaped cover (102), so as to cover the plate-shaped cover from the end to the root, separate the plate-shaped cover from the back and upper body clothes of people, play a protective role in preventing contact hygiene, and also enable the person sitting on the toilet to lean back to relax the body without worrying about hygiene. It also has the function of restricting the relative displacement between the protective cover and the toilet. Thus, it plays a fixing role (some also have the function of covering the hinge of the plate-shaped cover), and also has the function of restricting the relative displacement between the protective cover and the toilet. See Figure 12 .

[0064] In use, the lacing on the back of the upper part (201) is inserted through the end of the upright plate-shaped cover (102), so that the upper part (201) of the protective cover completely covers the plate-shaped cover or exposes the top of the plate-shaped cover. The middle part (202) of the protective cover is laid flat on the flat circular cover and completely covers the circular cover. The through hole (208) in the middle part is located above the circular cover to serve as a channel for excrement to fall. The lower part (203) hangs down to cover the front facade of the toilet, thus separating the front facade of the toilet from the human body and clothes to prevent contact infection. A little can be stuffed into the lower part near the top under the circular cover to play a fixing role, which is not shown in the figure. See Figure 12 (For the sake of simplicity, the little star is not shown in the figure).
