The invention discloses a covering device of a squatting pan inlet of a squatting pan toilet. The device is formed by connecting a cover (1) and trousers (2) and can also be provided with an upright pole (5) connected with the trousers (2) and a handle (4) connected with the upright pole (5). In another technical scheme of the device, the cover (1) is connected with the lower part of the trousers (2); the upper part of the trousers (2) is rotatably connected with the lower end of the upright pole (5); and the upper end of the upright pole (5) is connected with the handle (4); and a mechanism enabling the cover (1) to turn over relative to the upright pole (5) is comprised. Under the condition that the upright pole (5) is roughly vertical to the ground without changes, the cover (1) can be turned over from flat lying into vertical standing, thereby solving the problem that when the covering device is used for a small-area squatting pan toilet, after the cover (1) is removed from the squatting pan inlet, the cover (1) has nowhere to place when people go to the toilet. The invention has simple structure, low cost and easy manufacture, can beautify the environment of the squatting pan toilet and obviously improve the sanitary level of the squatting pan toilet.
