Abstract

A vapour trap cartridge has an entrance leading into a substantially vertical conduit. The conduit has a float located therein and narrows at a constriction. The conduit defines an exit having a lower edge and a cap located at the exit. The cup has a base and sides defining a reservoir therebetween and sides defining an upper edge above the lower edge of the exit so as to be able to collect a reservoir of urine therein in use into which the exit is submerged. As such, in use, the float seal against the constriction to define the physical vapour barrier which prevents odour emanation, including from the small reservoir of urine collected within the cup thereunderneath and the cup forms a further liquid vapour barrier. As such, the double vapour barrier effectively provides odour control for waterless urinal application.

Description

Improvement of waterless toilet

The present invention relates to an improvement of an anhydrous toilet. More specifically, the present invention relates to a vapor collection box for a urinal.

The waterless urinal vapor collection box includes a generally cylindrical body, and the generally cylindrical body is inserted into the urinal drain basin.

The box has an upper inlet through which urine flows into the vapor collection box.

Some configurations include S-shaped curved vapor traps (vapour traps), such as WO 2001/025554 A1 (ROEDIGER VAKUUM UND HAUSTECHNIK GMBH) published on April 12, 2001. Figure 6 discloses an S-shaped curved vapor trap ( vapour traps); another example is CN 101892701 B (FURU WEI) published on March 14, 2012, Figure 1 of which discloses a double S-curved vapor collector.

Other vapour trap configurations use floats, such as WO 1999/057382 A1 (KELLER) published on November 11, 1999. Figure 2 shows a float that can rise to block The height of the entrance of the urinal; or as shown in Figure 11, the aforementioned floating body can also float away without blocking the entrance.

A modern waterless urinal vapor collection box includes a reservoir, and the reservoir is provided with an overflow drainage weir to maintain a certain amount of urine in the reservoir and collect the sediment in the urine.

In addition, the density of the liquid sealant is relatively smaller than that of the liquid and floats on the top of the urine, and a vapour trap can be formed between the top of the urine and the top of the inlet, thereby reducing or eliminating Smell.

However, it is necessary to replenish the liquid sealant after approximately every 7000 times. In addition, common chemical detergents, such as bleach, may also have an adverse effect on the liquid sealant. Therefore, when disinfecting the urinal, it is necessary to use special and compatible chemicals.

In addition, the above-mentioned vapour trap may be blocked by sediment in the urine and needs to be maintained regularly.

The present invention seeks to provide a method to overcome or improve at least a part of the defects of the prior art, or at least to provide an alternative solution.

It should be understood that any document related to the prior art cited in this article does not imply that it is in Australia or other countries, and the document is part of the general knowledge in the field.

Disclosed is a steam collection box for a urinal, which can be inserted into the drain of the urinal. The vapor collection box includes an inlet through which urine flows into the vapor collection box in use, and the inlet leads to a substantially vertical duct.

The catheter has a floating body located in it. The float has a diameter of the float and the catheter has a narrowing constriction and the cross section of the constriction is circular. The constriction has a constriction diameter and the constriction diameter is smaller than the diameter of the floating body. The floating body is dropped to the constriction to seal the constriction to form a physical vapor barrier.

The duct defines an outlet with a lower edge and a cup located at the outlet. A liquid storage tank is defined between the bottom of the cup and the plurality of sides, and the plurality of sides defines an upper edge located above the lower edge of the outlet, so that in use, the urine collected in the liquid tank immerses the outlet to form Liquid vapor barrier.

In this way, in the state of use, the floating body seals the constriction to form a physical vapor barrier, which prevents the emission of odors, including odors emitted from a small amount of urine collected in the cup.

In addition, the liquid vapor barrier prevents the odor in the urinal drain pipe from overflowing.

When urine flows into the vapor collection box, the floating body floats and leaves the contraction part, so that the urine flows into the liquid storage tank, and the urine is discharged from the liquid storage tank to the drainage pipe.

In this way, the double vapor barrier prevents the smell of the waterless urinal from overflowing.

In addition, the vapor collection box provided by the present invention does not need to rely on a liquid sealant, and has infinite potential in application. And can be cleaned with common detergents.

In addition, through the vapor collection box of the present invention, the urine can be configured to flow freely, avoiding the urine sediment or crystallization problem of the existing vapor collection device. Specifically, the physical vapor barrier is located above the liquid vapor barrier. The design of the physical vapor barrier allows urine to flow through the catheter at a high speed into the cup, thus solving the problem of low flow rate of the existing urinals that require regular maintenance to prevent blockage.

In this way, the water consumption of the urinal can be reduced, or it can be The urinal does not require water.

According to the embodiment, the vapor collection box may include a body defining a liquid storage tank inside and an overflow hole passing through the body, and urine can flow out of the liquid storage tank from the overflow hole to move outside the body.

Here, the main body includes a side wedge, which abuts against the inner surface of the drain inlet, and forms a gap between the vapor collection box and the drain inlet. Urine can pass through the gap between the main body and the drain inlet of the urinal. Flow between. The side wedges are compressible, for example made of rubber or foam, so that the body can be squeezed into the drainage inlet.

The body may include an upper part and a lower cup body, and the upper part and the lower part jointly define a liquid storage tank in the body. The lower cup contains the aforementioned side wedge, so that when the upper part is periodically taken out, the lower part remains in its original position.
