[0048] Hereinafter, for each embodiment of the present invention, an explanation will be given based on the drawings. In order to make the technical features easy to understand, there are cases where parts of the technical features are enlarged in the drawings, but the dimensional ratios of the components are not necessarily the same as in reality.

[0049] Figures 1 to 9 This is the first embodiment of the present invention. As Figures 1 to 9As shown in the figure, the waterless toilet 100 of the present invention includes: a base 1 with a frame 2 provided on the top; the frame 2 is of a square structure and is composed of a front support rod 21, a rear support rod 22, a left support rod 23 and a right support rod 24, and a through opening 25 is formed in the middle part; a first roller 3 pivotally arranged between the front support rod 21 and the rear support rod 22; the first roller 3 has at least one concave portion 31; a second roller 4 is pivotally arranged between the front support rod 21 and the rear support rod 22 side by side with the first roller 3; when the concave portion 31 of the first roller 3 does not face the frame 2 or the second roller 4, the first roller 3 and the second roller 4 together airtightly seal the through opening 25 of the frame 2; two support frames 5 are respectively arranged on the top of the frame 2; two support plates 6, the first sides 61 of the two support plates 6 are respectively arranged on the two support frames 5, the second sides 62 of the two support plates 6 extend inwards and downwards relatively by a predetermined length, and there is a gap 63 between the second sides 62 of the two support plates 6; two cloth rolls 7 are respectively arranged on both sides of the base 1; a plastic cloth 71 is respectively wound on the two cloth rolls 7, the plastic cloths 71 of the two cloth rolls 7 are respectively laid on the two support plates 6, the plastic cloths 71 of the two cloth rolls 7 pass through the gap 63 between the two support plates 6, and then pass through between the first roller 3 and the second roller 4; a driving mechanism 8 can rotate the first roller 3 and the second roller 4 and drive the plastic cloths 71 of the two cloth rolls 7 to move downwards; a seat support 9 is arranged on the base 1; a toilet seat 91 is arranged on the seat support 9; a discharge port 911 is provided in the center of the toilet seat 91; with this structure, dirt can be collected without using water, the smell of concentrated dirt can be prevented from spreading, and the cost of consumables such as plastic cloth can be saved. The following will be described in detail.

[0050] As Figures 2 to 3 shown, a frame 2 is provided on the top of the base 1. The frame 2 is of a square structure and is composed of a front support rod 21, a rear support rod 22, a left support rod 23 and a right support rod 24, and a through opening 25 is formed in the middle part. The base 1 is mainly used to support components such as the frame 2. In addition, a separable storage tank 11 is provided at a position of the base 1 below the through opening 25 of the frame 2. The top of the storage tank 11 has an opening 111 communicating with the through opening 25 of the frame 2 for centrally placing dirt to facilitate subsequent treatment.

[0051] As Figure 4 shown, the first roller 3 and the second roller 4 are pivotally arranged between the front support rod 21 and the rear support rod 22 side by side. The first roller 3 has at least one concave portion 31.

[0052] When the concave portion 31 of the first roller 3 does not face the frame 2 or the second roller 4, the first roller 3 and the second roller 4 together airtightly seal the through opening 25 of the frame 2 to prevent the smell of the dirt in the storage tank 11 from spreading.

[0053] In the first embodiment, mainly by the structure that the first roller 3 and the second roller 4 are together against the inner side of the frame 2, and the first roller 3 and the second roller 4 are against each other with a plastic cloth 71 in between, so as to achieve the effect of air-tightly closing the through-opening 25 of the frame 2 by the first roller 3 and the second roller 4 together. In fact, a soft pad or other airtight structure (not shown in the figure) can also be provided between the first roller 3 and the frame 2 and between the second roller 4 and the frame 2.

[0054] The periphery of the opening 111 of the storage tank 11 can also be airtightly joined to the frame 2 to further prevent the smell of the dirt in the storage tank 11 from dissipating. Specifically, as Figure 3 shown, the smell of the dirt stored in the storage tank 11 can only dissipate outward through the through-opening 25 of the frame 2 from the opening 111 of the storage tank 11. Therefore, as Figure 4 shown, when the first roller 3 and the second roller 4 together airtightly close the through-opening 25 of the frame 2, it can effectively prevent the smell of the dirt in the storage tank 11 from dissipating.

[0055] As Figures 6 to 8 shown, for the convenience of description, the diameter direction X of the first roller 3 is defined as the width direction of the concave portion 31 of the first roller 3. The width W1 of the concave portion 31 of the first roller 3 is less than the diameter D1 of the first roller, so that there are at least two sealing sides 32 on the first roller 3 (the positions of the sealing sides 32 are represented by a grid in Figure 7 ). The two sealing sides 32 are the widest structures on the first roller 3, and the two sealing sides 32 of the first roller 3 can airtightly close the through-opening 25 of the frame 2 together with the second roller 4; on the contrary, when the first roller 3 is rotated so that the concave portion 31 of the first roller 3 faces the second roller 4, the waterless toilet 100 can provide the dirt to pass through the through-opening 25 of the frame 2. When the concave portion 31 of the first roller 3 does not face the frame 2 or the second roller 4, the two sealing sides 32 of the first roller 3 are respectively against the second roller 4 and the frame 2, so that the first roller 3 and the second roller 4 together airtightly close the through-opening 25 of the frame 2 to prevent the smell of the dirt in the storage tank 11 from dissipating.

[0056] As Figure 5 shown, the position of the gap 63 between the two support plates 6 is correspondingly arranged above the first roller 3 and the second roller 4 to facilitate the concentration of dirt.

[0057] As Figure 9 shown, the plastic cloths 71 of the two cloth rolls 7 are respectively laid on the two support plates 6, and the plastic cloths 71 of the two cloth rolls 7 respectively pass through the gap 63 between the two support plates 6 and then pass between the first roller 3 and the second roller 4. As Figure 8As shown in the figure, in the state where there is no dirt, the plastic sheet 71 is clamped by the first roller 3 and the second roller 4, so the plastic sheet 71 is in a taut state. When dirt falls onto the plastic sheet 71, it drives the cloth roll 7 to roll and extend more plastic sheet 71, so that the plastic sheet 71 and the dirt are concentrated in the concave portion 31 of the first roller 3.

[0058] The plastic sheets 71 of the two cloth rolls 7 are in sheet form, which is convenient to manufacture and can save costs compared with the commonly used long strip bag body. In addition, since the plastic sheets 71 are convenient to manufacture, by using a longer cloth roll 7, the service life of the cloth roll 7 can be increased, and the number of times of replacing consumables such as the cloth roll 7 can be reduced. The plastic sheets 71 can be made of biodegradable materials to facilitate subsequent disposal.

[0059] The dimensions of components such as the first roller 3, the second roller 4 and the storage tank 11 in the drawings are only set for convenience of explanation. In practice, for example, the size of the recess 31 of the first roller 3 is larger than the amount of dirt generated at one time, and the capacity of the storage tank 11 can accommodate the plastic sheet 71 of the entire cloth roll 7.

[0060] The driving mechanism 8 can be a mechanism powered by manual or foot-operated forces, or an electric mechanism powered by a motor, etc. In this embodiment, a structure with a manual rocker is used as an example. For example, the driving mechanism 8 can further include: a first gear 81, which is linked to the first roller 3; a second gear 82, which is linked to the second roller 4, and the second gear 82 is meshed with the first gear 81; a rocker 83, which is linked to the first gear 81, and the rocker 83 can rotate the first roller 3 to drive the second roller 4, and the first roller 3 and the second roller 4 clamp together to drive the plastic cloth 71 of the two cloth rolls 7 to move downward.

[0061] The seat support 9 is used to support the toilet seat 91. In this case, the vertically upward area of ​​the two support plates 6 can be larger than the vertically upward area of ​​the discharge port 911 of the toilet seat 91, so that the plastic sheet 71 laid on the support plate 6 can completely receive the dirt falling from the discharge port 911 of the toilet seat 91. In addition, in other embodiments, the height of the seat support 9 can be slightly higher than the two support frames 5, that is, without affecting the rotation of the cloth roll 7, the bottom of the toilet seat 91 is made as close to the first side edge 61 of the support plate 6 as possible, so that the plastic sheet 71 on the support plate 6 can completely receive the dirt falling from the discharge port 911 of the toilet seat 91.

[0062] like Figure 4 As shown, when the first roller 3 and the second roller 4 together seal the through opening 25 of the frame 2, the first roller 3 and the second roller 4 can prevent the smell of the dirt in the storage tank 11 from being emitted. Figure 2 and Figure 9As shown in the figure, after the dirt falls from the discharge port 911 of the toilet seat 91, since the vertically upward area of the two support plates 6 is larger than the vertically upward area of the discharge port 911 of the toilet seat 91, even if the dirt splashes downward and outward, it will be completely received by the plastic cloth 71 on the support plates 6 and fall into the recess of the first roller 3 from the gap 63 between the two support plates 6. As Figure 8 shown in the figure, when it is necessary to concentrate the dirt, the drive mechanism 8 is used to rotate the first roller 3 and the second roller 4 by more than half a turn until all the dirt falls into the storage tank 11, and then the first roller 3 and the second roller 4 are returned to the state where they airtightly seal the through hole 25 of the frame 2 as Figure 4 shown in the figure. Through the above structural design of this embodiment, the dirt can be collected without using water, and the cost of consumables such as plastic cloth can be saved.

[0063] Figure 10 This is the second embodiment of the present invention. As Figure 10 shown in the figure, at least one radial soft pad 33a is provided beside the recess 31a of the first roller 3a, and the radial soft pad 33a is arranged around the surface of the first roller 3a along the diameter direction of the first roller 3a. The radial soft pad 33a can cooperate with the first roller and the second roller to clamp the plastic cloth with a predetermined pressure, so as to drive the plastic cloth to move downward when the first roller and the second roller are rotated.

[0064] Figure 11 This is the third embodiment of the present invention. As Figure 11 shown in the figure, at least one axial soft pad 34b is provided beside the recess 31b of the first roller 3b, and the axial soft pad 34b is arranged on the surface of the first roller 3b along the central axis direction of the first roller 3b. The axial soft pad 34b can be filled between the first roller and the second roller when the first roller and the second roller airtightly seal the through hole of the frame, so as to prevent the smell of the dirt in the storage tank from spreading.

[0065] To achieve a better airtight effect. The axial soft pad 34b can be used together with the above-mentioned radial soft pad 33a.

[0066] Figure 12 This is the fourth embodiment of the present invention. As Figure 12 shown in the figure, the second roller 4c has a recess 41c corresponding to the recess 31c of the first roller 3c for concentrating dirt. In addition, the second roller 4c is also provided with a radial soft pad 43c and / or an axial soft pad 44c corresponding to the first roller 3c.

[0067] The above are the embodiments listed in the present invention, which are only for convenience of description and should not be used to limit the present invention. That is, all various transformation designs made according to the content of this application should be included in the protection scope of the present invention.
