When the rotating base is used, the upper part of the rotating disk 2 needs to be connected to the shell 4 of the existing waterless toilet, and the design of the rotating disk 2 is convenient for connecting with the shell 4 of the existing waterless toilet.

[0038] like Figures 7 to 9 As shown, a waterless toilet with the rotating base includes the rotating base described in this embodiment, and the shell 4 of the waterless toilet is connected to the upper part of the turntable 2. Specifically, in this embodiment, the waterless toilet is arranged in a motorhome. For the convenience of description, in this embodiment, it is assumed that the user faces forward when sitting down to use the toilet, and the button 31 is located at the front side of the waterless toilet, so that it is convenient to press the button 31 to install the waterless toilet relative to the rotating chassis in a motorhome with limited space, or to press the button 31 to rotate the waterless toilet relative to the rotating base. First, the waterless toilet can be adaptively installed in various orientations at any time according to the actual installation scene, and second, the user can change the toilet direction of the waterless toilet according to his own toilet habits when using it.

[0039] The assembly process of the rotating base is as follows:

[0040] First, the button 31, the push plate 321, the lever 322 and the slide buckle 33 are placed in the corresponding positions of the installation groove 13 in sequence, and the push plate 321 is pressed against the first spring 34, and the slide buckle 33 is pressed against the second spring 35, and then the cover plate 14 is fixed on the base body 1 to close the installation groove 13. Figure 2As shown, the button 31 is pressed down again, and the button 31 drives the push plate 321, the lever 322 and the slide buckle 33 in sequence, so that the two slide buckles 33 slide away from each other. At this time, the lower part of the turntable 2 can be inserted into the annular groove 11, and the conical hole 22 of the turntable 2 is sleeved on the round table 12, and the upper part of the turntable 2 is located above the annular groove 11. The button 31 is released again, and the button 31 is reset under the action of the first spring 34. At the same time, the slide buckle 33 slides and resets close to the limiting flange 21 under the action of the second spring 35 until the slide buckle 33 hooks the limiting flange 21 to limit the axial movement of the turntable 2, and the slide buckle 33 maintains the limiting state of hooking the limiting flange 21 under the action of the second spring 35, ensuring that the slide buckle 33 is firmly hooked on the limiting flange 21 without slipping, and the assembly of the rotating base is completed. Figure 1 shown.

[0041] The installation process of this waterless toilet with swivel base is as follows:

[0042] First, install the assembled rotating base to the reserved position of the RV, such as Fig. 9 As shown, please note that the turntable 2 is separated from the rotating base as an independent component. After the independent turntable 2 is installed to the bottom of the shell 4 of the waterless toilet, the assembly process of the turntable 2 is repeated to complete the assembly of the turntable 2. The direction of the waterless toilet can be adjusted according to the actual reserved position. Just press the button 31. The button 31 drives the push plate 321, the lever 322 and the slide buckle 33 in turn, so that the two slide buckles 33 slide away from each other until they are separated from the limit flange 21. At this time, the turntable 2 can be rotated to any angle to adjust the direction of the waterless toilet. Then release the button 31 to complete the installation of the waterless toilet with the rotating base. Figure 7 When the user uses the waterless toilet, the direction of the waterless toilet can be changed according to the user's own toilet habits. There are two ways to change the direction of the waterless toilet. One is to directly rotate the shell 4 of the waterless toilet. By overcoming the resistance of the second spring 35, the shell 4 of the waterless toilet drives the turntable 2 to rotate to adjust the direction of the waterless toilet. The second spring 35 makes the turntable 2 have a certain damping when rotating, which improves the user's operating experience. The second is to press the button 31. As mentioned above, the two sliders 33 slide away from each other until they are separated from the limit flange 21. At this time, the turntable 2 can be rotated to any angle to adjust the direction of the waterless toilet, which greatly reduces the operating intensity and makes the operation more convenient. The disadvantaged groups can also operate it easily.
