FIELD

The contents of this application involve composting toilets, portable toilets and straight toilets. A straight toilet refers to a toilet without an S-shaped water seal that has a valve at the bottom.

PRIOR ART

It is common to be able to see composting toilets and portable toilets on the market. Both types of toilets have an unpleasant odor and attract mosquitoes and flies, and portable toilets splash solid and liquid waste, which is annoying to users. We can make a waterless toilet that is better at these aspects.

SUMMARY

An odor-proof, splash-proof waterless toilet, comprising: a funnel-shaped soft passageway, hereafter referred to as passageway, and a pressing member. Said pressing member is located on one side of the peripheral circle of said passageway, exerting pressure on said passageway, deforming said passageway until said passageway is closed. When said pressing member reduces pressure, said passageway opens. The said pressing member can be a curved shape, and is tangential to the peripheral circle of said passageway. When the passageway is closed, it prevents odor and splashing.

SPECIFICATIONS AND EMBODIMENTS

This application describes an odor-proof, splash-proof waterless toilet, comprising: a funnel- shaped soft passageway made of high polymer material, hereafter referred to as passageway, and a pressing member. Top end of said passageway is connected to the toilet and hangs below it, forming an open funnel shape. The user's excreta pass through the top end of passageway, and fall through the middle part and bottom part, and slide out of the bottom end, entering the solid and liquid waste. Said pressing member is located on one side of the peripheral circle of said passageway, exerting pressure on said passageway, changing the shape of said passageway until said passageway is closed. When said pressing member reduces pressure, said passageway opens. The said pressing member and the peripheral circle of said passageway is a tangential curve. When the passageway is closed, it prevents odor and splashing. Because the passageway is soft, exerting pressure to the outside of passageway causes changes in the sectional surface of the passageway as well as the ability of the passageway to allow material to pass through, from a large amount to a small amount until nothing, the passageway closes. Reducing pressure causes changes in the sectional surface of the passageway as well as the ability of the passageway to allow material to pass through, from nothing to a small amount until a large amount, the passageway opens.

The said pressing member and the peripheral circle of said passageway may be externally tangent to each other, or they may be internally tangent to each other; the said pressing member may be an irregular curve, it may be internally tangent to the peripheral circle of said passageway, or it may be externally tangent to the peripheral circle of said passageway, said pressing member may be located on one side of the peripheral circle of said passageway, or it may be multi-sided. Said pressing member may be hard material, or it may be soft material. Said pressing member that is tangential to the peripheral circle of said passageway may be a curved pressure bar, or multiple curved pressure bars, such as multiple scissor shaped curved pressure bars, or it may be an inhaul cable, or it may be multiple inhaul cables, or it may be a curved overlapping inflatable ring, or it may be key ring shaped overlapping inflatable ring.

Said pressing member that is tangential to the peripheral circle of said passageway may be a straight pressure bar. Said straight pressure bar is tangential to the passageway, or there may be multiple straight pressure bars with multiple tangent points that are not on the same diameter. When multiple pressure bars are used, they apply shearing force to the passageway, such as a scissor-shaped two straight pressure bars with two tangent points, three straight pressure bars with three tangent points, or four straight pressure bars with four tangent points.

Said pressing member may be multiple pressing members used together, and may be multiple identical members, such as two juxtaposed curved pressure bars, or multiple non-identical members, such as curved pressure bar juxtaposed with an inhaul cable.

The user's excreta fall into passage with the lower end pressing member closed. After the user finishes use, the upper track pressing member closes and the lower track pressing member opens, and the excreta slide out the bottom end of passageway and into the solid and liquid waste. In the same way that this process allows the excreta to pass through easily, it also does not allow any opportunity for odor, mosquitoes and flies to come out, and it does not cause splashing.

Another method is that the user's excreta fall on to the passageway with the upper track pressing member closed. After the user finishes use, the upper track pressing member opens, and the excreta fall on to lower track of the passageway with the lower track pressing member in the closed position. The upper track pressing member closes, and for a short time, the excreta is located in the passageway with both upper track and lower track pressing members closed. The lower track pressing member opens, and the excreta slide out the bottom end of passageway and into the solid and liquid waste. In the same way that this process allows the excreta to pass through easily, it also does not allow any opportunity for odor, mosquitoes and flies to come out, and it does not cause splashing.

The force of said pressing member may be from a human motion, or from winding, or from a flywheel, or from a high position weight, or compressed air, or from hydraulic pressure, or from solar energy, or form wind energy, or from electricity. The reciprocating motion of said pressing member is mechanical transmission, it may be a gear drive, or a screw drive, such as a pneumatic piston and crankshaft connecting rod drive, are all able to achieve the reciprocal motion of the pressing member.

Said high polymer funnel-shaped soft passageway may be formed from soft rubber, soft plastics, thermoplastic elastomers, or a compound of them and a compound using reinforcing fibers as a sandwich layer and surface layer.
