Toiler odor blocking system
Kind Code:

This invention odor blocking invention has two claims.

The object of this invention is to block any odor from escaping the toilet before it contaminates the whole bath room. Older toilets used more water, human waste had a chance to sink into the water, therefore blocking most odor from escaping.

Low flush toilets use only 1.6 gallons of water, water saving is offset by generating more odor. Since most human waste remains above the waterline it generates unavoidable odor.

1 This toilet odor blocking bubbler system is mountable inside or outside of the toilet tank. The odor blocking system consist of small water container filled with soapy, scented water, foam, or some cases chemical spray to be pumped into the toilet tank to cover the human waste. Air pump creates bubbles in the tank, bubbles flow through the hose guiding bubbles into the toilet tank. By covering the human waste with scented soap bubbles it blocks any odor from escaping into the surrounding area.

Pressurized foam can also be used to block odor from escaping.

2 The bubbles to cover the human waste as shown on FIG. 2 is guided through an embedded hose in the toilet seat. The object of this invention is to cover the excrement with bubbles (or foam) as fast as possible. Depending on the air pressure, volume of bubbles, design of toilet seat, several bubble nozzles could be installed for optimized area saturation.

What is claimed is:

1. Odor blocking is a low cost soap bubble innovation. Small container, such as a plastic bottle filled with soapy water attached to the toilet tank (or located inside the tank itself), aquarium type air pump pumps the air into the closed bottle creating the bubbles. Larger diameter plastic hose guides the bobble stream from the bubbler into the toilet bowl covering the human waste. Hose can be inserted between the toilet bowl and the toilet seat. Liquid soap based bubble or similar scented chemical can be pumped or sprayed on top of the excrement to block any embarrassing odor from escaping into the room. This invention makes the air freshener cans just about obsolete.

2. The bubbles to cover the human waste as shown on FIG. 2 is guided through an embedded hose in the toilet seat. The object of this invention is to cover the excrement with bubbles (or foam) as fast as possible. Depending on the air pressure, volume of bubbles, design of toilet seat, several bubble nozzles could be installed for optimized area saturation. Foam under pressure can also be used, as the claim of this invention is, to cover the excrement



[0001] The newer toilets in most parts of the USA are water saving low flush type. The human waste in the toilet bowl is exposed with less quantity of the water and creates an even greater need for a workable odor venting system for toilets. There are several innovations dealing with this kind of problem hardly any on the market due to cumbersome or impractical design. Some have inserts under the toilet bowl, some are above and on the back, and of course all need to use ventilator with a manual or automatic switch. Ventilated air should leave the toilet bowl before it reaches the ceiling or the wall type exhaust fan. Some prior art design require the vented air to be connect to the in wall vent pipe to sanitary tee. This Toilet odor blocking system invention is a low cost approach to solve the problem by blocking the odor at it's source before the whole area gets “polluted”.


[0002] The odor blocking invention consist of an air pump creating bubbles in a soapy container and the bubbles are guided into the toilet tank covering the human waste and blocking any odor from escaping. Scented liquid soap, water mixture, or chemical deodorant can be used in the bubbler. In some locations/commercial/pressurized foam can also be used. Soap bubbles or foam can be flushed away at any time without any problem and will greatly improve on the hygiene.


[0003] FIG. 1 shows a standard toilet bowl (1) with flushing water intake (8), sewage outlet (9). Air pump (2) is plugged into AC (20) on/off switch (10) attached to the side of the tank or bowl and optional pressure sensitive switch(5) can activate the air pump and it pumps the air trough hose (6) into the bubbler (3). Bubbler (3) is filled with soapy water trough cap(7). When air pump (2) is on, the bubbles are forced to flow trough the bubble hose (4)into the toilet bowl(1). Human excrement (18) gets covered with bubbles (19) blocking any odor escape. Bubbler can be shut off manually by switch (10) or automatically by the pressure sensor (5).

[0004] FIG. 2 show a toilet tank(14) with side mounted bubbler (3). Toilet tank valve (16) fills up the tank, and also keeps the bubbler(3) full of water by using hose (15) trough a check valve (21). When the air pump (2) is on, bubbles are forced out trough the bubble hose (4)Bubbles can be guided using the overfill tube in the tank, since it connects direct to the bowl (1) all around inside. Toilet seat (17) has an embedded bubble hose(13) providing a faster bubble coverage.

[0005] FIG. 3 shows a close up view of the bubbler (3) with automatic water filler wit water intake (15), air intake (6) and (25). Extended cap(23) is the liquid soap container, water(24) mixed with soap, bubbles (19) are forced out on hose(4).

[0006] FIG. 4 shows the rear view of the toilet tank(14) and bowl(1), on the side pressure filled foam container (29) generating water soluble foam or bubbles (19) /similar to shaving cream/. Foam spraying can be manual or automatically activated.


[0007] The Odor blocking invention blocks the odor evaporation from the human waste by covering it with scented soap bubble, chemical thin layer spray, or water soluble foam. After flushing, soapy bubbles also create a cleansing, refreshing effect. Bubbler (3) containing soapy water activated by the air pump (2) Odor blocking could also be achieved by blowing, spraying other type of chemical agents to cover the excrement. Bubbles act as a very inexpensive barrier to block the odor before it reaches the ceiling fan. In respect, after explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention, nor is it intended to be limiting as to the scope of the invention in any way.
