This will be explained in detail below.

The frame 1 can adopt various structures, and it is mainly used to support the ring body 2 and the elongated bag body 3.

The ring body 2 is used to make the elongated bag body 3 in a stretched state.

The structure of the elongated bag body 3 is tubular, and its bottom 31 can be knotted (as shown in Figure 2), hot melted (not shown in the figure), clamped (not shown in the figure) or other methods (not shown in the figure). Show) closed to collect dirt.

The elongated bag body 3 adopts a flexible body that can be folded and stored. Therefore, when the bottom 31 of the bag body 3 is arranged inside the ring body 2, most of the predetermined parts are still there. All 3a can be folded and stored around the frame 1, which can increase the frequency of use. The inner diameter D1 of the elongated bag body 3 should be greater than the outer diameter D2 of the ring body 2, so as to facilitate the eversion of the predetermined portion 3a to the outside of the ring body. In addition, when the bottom of the elongated bag body 3 and the elongated side edges 32 are placed inside the ring body 2, the various parts of the elongated side edges 32 can be folded to reduce the length of the elongated bag body 3. The overall inner diameter, however, for the convenience of illustration, the various parts of the elongated side portion 32 are omitted in each figure to be folded to reduce the folding lines of the overall inner diameter of the elongated bag body 3.

The elongated bag 3 is mainly used to collect dirt. Because it has a sufficient length, after use, the bottom can be folded to quickly achieve preliminary cleaning, so as to facilitate the next use. In addition, the elongated bag body 3 can be made of a biodegradable material to facilitate subsequent processing. Compared with conventional bedpans, urinal chairs and other structures, the elongated bag body 3 at least has the advantages of convenient and quick initial cleaning and no need for cleaning.

As shown in Figures 4-6, the combination of the frame 1, the ring body 2 and the elongated bag body 3 is mainly used to collect dirt without the use of water. However, the dirt generally emits an odor. Therefore, in order to solve For the problem of the odor emission of dirt, the bottom of the frame 1 can be further provided with a roller device 4, a gate device (not shown in the figure) or other sections that can close the long strip bag 3 that has contact with the dirt. Use the structure of part 3b (not shown in the figure) to prevent the smell of dirt from escaping.

A front support frame 11 and a rear support frame 12 can be provided at the bottom of the frame 1, and a roller device 4 is connected. The roller device 4 includes a first module 41 with a first rotating shaft 411 and a first roller 412; The first shaft 411 is pivoted between the front support frame 11 and the rear support frame 12; and a second module 42 has a second shaft 421 and a second roller 422; the second shaft 421 is pivoted on the front Support frame 11 and behind And a drive mechanism 43 connected to the first shaft 411, which can rotate the first shaft 411, and can drive the first roller 412 to rotate in the direction of the second roller 422; and a transmission mechanism 44, connected to the first The rotating shaft 411 and the second rotating shaft 421 can drive the first roller 412 and the second roller 422 to rotate in opposite directions when the first rotating shaft 411 rotates. The roller device can be used to close a part of the elongated bag body 3 in sections, especially for closing the used part 3b of the elongated bag body 3 that is in contact with dirt.

The frame 1 can be installed in various suitable places, for example, where there is a preset groove below (not shown in the figure), or a bottom bracket 13 (as shown in Fig. 18) is arranged under the frame 1, or in addition A number of brackets are erected under the toilet seat (not shown in the figure).

The driving mechanism 43 is connected to the first rotating shaft 411, can rotate the first rotating shaft 411, and can drive the first roller 412 to rotate in the direction of the second roller 422. It can use an electric mechanism such as an electric motor to save manpower, or it can be used for example Force-driven mechanisms such as manual and foot pedals (not shown in the figure).

The transmission mechanism 44 connects the first rotating shaft 411 and the second rotating shaft 421. When the first rotating shaft 411 rotates, it can drive the first roller 412 and the second roller 422 to rotate in opposite directions. It can use gears, belts (not shown in the figure). Show) and other common transmission mechanisms, examples are as follows. The transmission mechanism 44 may include: a first gear 441 arranged on the first rotating shaft 411; and a second gear 442 arranged on the second rotating shaft 421 and meshing with the first gear 441.

When the used part 3b of the long bag body 3 containing dirt passes through the first roller 412 and the second roller 422, the dirt will be squeezed and deformed. However, for the convenience of illustration, it is shown in all the figures. Replace the dirt with the same oval shape.

As shown in Figures 4-6, when the dirt 101 is placed in the elongated bag 3, the first rotating shaft 411 is rotated to make the first roller 412 and the second roller 422 roll, and then the elongated bag The used part 3b of 3 and the dirt 101 are brought under the first roller 412 and the second roller 422. In addition, the first roller 412 and the second roller 422 can also be used to close the used portion 3b of the elongated bag body 3, so as to prevent the smell of dirt from escaping.

As shown in FIGS. 7 to 8, the surface layer of one or both of the first roller and the second roller may have an elastic layer. The following is an example of the first roller having an elastic layer. As shown in Figure 7, there is an elastic layer 413a on the surface of the first roller 412a, which can make the first roller and the second roller close together in a tight-fitting manner, when the dirt is to be driven through the first roller and the second roller In the case of two rollers, the elastic layer 413a can be used as a buffer structure, and after the dirt passes, the first roller is still close to the second roller, which can surely seal the used part of the long bag. As shown in Figure 8, when both the first roller 412b and the second roller 422b are provided with an elastic layer 413b, 423b, it is different from only the elastic layer provided on the first roller (as shown in Figure 7) or only the second roller. Compared with the structure of the elastic layer (not shown), the amount of dirt allowed to pass between the first roller 412b and the second roller 422b can be increased.

As shown in Figs. 9-17, one or both of the first roller and the second roller may have a hollow part, and the second roller has a hollow part as an example for description as follows. As shown in Figure 9, the second roller 422c has a hollow portion 424c, which can facilitate the passage of dirt between the first roller 412c and the second roller 422c, so that there is no need to reserve between the first roller 412c and the second roller 422c. The space for the dirt to pass through can be close together as close as possible. When the dirt is to be driven through the first roller 412c and the second roller 422c, the hollow part 424c can contain the dirt, and After the dirt has passed, the first roller 412c is still close to the second roller 422c, so that the used part of the elongated bag can be reliably closed.

As shown in FIGS. 10-16, when the second roller 422c has a hollow portion 424c, a Programmable Logic Controller 45 can be used to control the driving mechanism 43, so as to control the second roller 422c to rotate every time One turn enables the first roller 412c and the second roller 422c to always stay close together (as shown in FIG. 16), so that the used part 3b of the elongated bag body is surely closed.

As shown in FIG. 17, when the first roller 412d and the second roller 422d both have hollow portions 414d and 424d, it is different from only the first roller having a hollow part (not shown) or only the second roller having a hollow part. Compared with the structure of the part (as shown in FIG. 10), the amount of dirt allowed to pass between the first roller 412d and the second roller 422d can be increased.

As shown in FIG. 18, a storage barrel 5 can be provided under the first roller 412 and the second roller 422 to temporarily store the elongated bag 3.

As shown in FIG. 19, the present invention further provides a water-free toilet 200, which includes: a toilet body 201, which can be set on the ground; and a toilet seat 202, which is set on the toilet body 201 and has a drain 203; And a water-free sewage discharge device 100, which is arranged under the toilet seat 202; with this structure, dirt can be collected without using water.
