Description
The following statement is a full description of this invention, including the best method of performing it known to me: 2025202069 21 Mar 2025 TITLE OF YOUR INVENTION AIR FILTRATION SYSTEM / PURIFIER TECHNICAL FIELD This invention relates to a device that collects and removes all foreign (5) particles from the air like dust and other impurities and reduces humidity significantly by using the method of mixing water into air above the surface of the water. BACKGROUND OF THE INVENTION Our planet’s air has become very dirty and unhealthy, full of small, (10) microscopic par0cles from pollu0on, smoke, dust, pollen and ash. All these par0cles we see floa0ng around inside our homes when the sun shines through our windows. Many of these par0cles we inhale and the rest fall on our floors, our furniture, even in our food. We can dust one day and the next day our homes are again full of dust. All these par0cles which (15) are in the air my purifier collects and produces clean air to breathe and at the same 0me keeps homes clean. By filtering the air, we protect all our family members, especially our babies and the elderly from allergies such as asthma, high fevers and any other breathing illnesses. The device cleans the air by using water. There are many water filters using (20) the method of washing the air into the water, but they produce lots of bubbles which float out of the filter thus causing lots of moisture and carry a lot of dirty air. Consequently, people do not trust them anymore. My purifier solves the problems of bubbles and moisture as it uses a separa0on system which separates the air from the moisture and even (25) collects the humidity from the air and destroys all the bubbles on the water surface not allowing any bubbles to escape. These days purifiers use filters and those that have prevailed are very sophis0cated and clean the air of foreign par0cles. However, air carries lots of humidity, some0mes up to 70% or more, and as the air travels (30) though the filter it becomes wet and the dirt that has collected becomes 2025202069 21 Mar 2025 muddy crea0ng blockages, destroy the filter or by making holes and the air comes out unfiltered. My purifier never blocks, and the humidity improves the func0oning of the purifica0on system. The air always comes out totally clean and dehydrated and perfect for healthy breathing for all (5) our family members. Mother nature gave us the best air filtra0on system on the planet, the oceans. Ocean air is totally clean without any dust, smoke, pollu0on, pollens or any other foreign par0cles because it uses the method of mixing the water into the air and above the surface of the water especially if it’s (10) windy. The air in the ocean hits the surface of the water again and again, moves through the waves and becomes fully wet and as it travels upwards meets other dry air which becomes wet too and as it hits the surface again the moisture falls into the water carrying all the dirt and the air becomes totally clean. My purifier uses exactly the same method of mixing the (15) water into the air and above the surface of the water inside a system of pipes, the mixing pipes, and cleans the air. If one is on a boat or close to the coast and it’s a bit windy one will become wet from the ocean spray. This issue is overcome by my purifier by using a separa0on system which separates the air of any moisture, collects the (20) humidity and at the same 0me the water carrying all the dirt drops to the base of the container and only clean air comes out moisture free. SUMMARY OF THE INVENTION My inven0on, a purifier, is a very simple device and easy to manufacture. It is made up of three parts, the container, the lid of the container plus the (25) purifica0on system. All these parts can be made from plas0c or metal. The container is shaped like a bucket or any other shape that suits the purpose. The bucket shape allows for a bigger separa0on system. A line surrounds the container above its base which indicates the water level as the purifier works with a specific level of water. The lid screws onto the container and at the (30) centre of the lid and fixed to the lid is the entrance pipe. The entrance pipe drops down close to the water level and carries the rest of the purifica0on system, the mixing pipes and the separa0on system. Multiple small exhaust holes surround the entrance pipe on the lid's surface that carry the clean air 2025202069 21 Mar 2025 out of the purifier. Alterna0vely, we can use two exhaust pipes, one on each side of the entrance pipe and larger than the entrance pipe, for the air to escape freely. The entrance pipe drops downward close to the surface of the water stops (5) and separates in two, or more pipes, the mixing pipes. The mixing pipes feature an open curve with a small sec0on dipping just below the water’s surface. This reduces the water pressure and achieves the best airflow. The sec0on of the mixing pipes si>ng under the water contain a hole, the receiving hole, from where the mixing pipes draw water to be mixed with (10) the air. The small sec0on of the mixing pipes, with an open curve, rises above the water's surface, traveling upward with addi0onal curved angles. These curved angles help mix the water into the air inside the mixing pipes and above the surface of the water. The mixing pipes are assisted by the curving angles un0l all the air becomes moisturised and finishes at the top (15) of the interior of the separa0on system. The final curve directs the airflow to disperse evenly throughout the upper sec0on of the separa0on system and the entrance pipe, enhancing proper moisturisa0on. The separa0on system consists of three parts, the upside-down bowl (or bowl), the extension wall and the entrance pipe, that comes through to (20) the middle of the bowl a small distance from the container’s lid. The length and width of the separa0on system varies according to the size of the purifier to leave enough space between the container and the separa0on system so that the clean air can escape out of the purifier. The interior of the bowl is air0ght, only the boAom is open. I refer to this as the mouth (25) which is a bit wider than the top of the bowl. This allows the air which flows out to cover all the surface of the water and lower part of the inside wall of the container. The outside of the bowl is smooth and tapers down towards the mouth of the bowl, but before and close to the mouth it has an extension wall surrounding the bowl with a corner sloping downward (30) towards the wall of the container and finishing at the same level as the level where the bowl ends, leaving a small space between the wall of the container and the separa0on system enough for the clean air to escape. Inside of the bowl, the uppermost sec0on and all around the entrance pipe is smooth as is a small sec0on of the bowl’s wall that curves (35) downward. The remainder of the wall slopes downward in a ridge and channel forma0on to the boAom of the bowl. The lower part of the 2025202069 21 Mar 2025 channel is parallel to each other in distances of approximately 2-3 centre meters. Between the channels are the ridges. The ridges sit some millimetres above the channels and on the top form a corner which descends from both sides to the channels allowing all the water from the (5) top of the bowl to flow inside the channels and fall to the base of the container. Without the channels small drops of water near the edge of the mouth may be blown out of the purifier by air. The mixing pipes, which are opposite each other, blow all the moisturised air to the top of the bowl and the entrance pipe spreading it all over the upper sec0on of the (10) interior of the bowl. This process starts the separa0on of the air from the moisture and the air filtra0on. All the moisture together with the humidity turns to water which has trapped all the dirt from the air. It then drops downward some from the mixing pipes, some from the entrance pipe, however most of the water drops from the channels and as the water (15) falls to the base it forms lots of bubbles which try to escape from the surface of the water. This is the first stage of separa0on and filtra0on of the air which happens inside the separa0on system. The second stage happens under the separa0on system. The air comes down from the mouth of the bowl and gently hits the surface of the water thus destroying (20) all the bubbles. The moisture and the dirt they carry is trapped into the water and only the air escapes traveling to the sides and hi>ng the wall of the container. Any remaining moisture is caught there forming small drops which slowly slide downward. To func0on efficiently the separa0on system must be the correct size and (25) distance from the surface of the water for the air to hit the water gently. Some air, which flows downward, does not reach the surface of the water, it turns up and hits the inside container wall together with air which is underneath. Some air escaping out of the edge of the mouth meets the extension wall of the separa0on system as it turns upward and together (30) with addi0onal air travels up and turns this air downward hi>ng the inside container wall for the last 0me. As the air hits the wall of the container any remaining moisture and dirt in the air form small drops which s0ck to the container wall and slowly slide down to the water and the clean air, without moisture, travels up and out from the exhaust holes or pipes (35) which are on the top of the lid, and perfect for healthy breathing. In all the purifier designs, the operational processes take place above the water surface, while the water below remains undisturbed down to the base, 2025202069 21 Mar 2025 except for the disturbance caused by water falling from the separation system which generates bubbles. All my purifier designs, in any size, with one, two or more entrance and mixing pipes, work two ways. Air can be blown into the purifier from the (5) entrance pipe or alterna0vely clean air can be drawn out from the exhaust pipe. My purifier will never block if the fan which sends the air to the inside of the entrance pipe draws the air from a grill with holes smaller than the opening of the mixing pipes and the opening of the receiving holes. (10) Alterna0vely, if we draw the clean air from the exhaust pipe then the entrance pipe, or pipes, draw the air from a grill with holes smaller than the receiving holes. In addi0on, the air sent from the fan to the purifier must be cool, not hot, or the water will steam. This purifier design, featuring the entrance pipe in the centre, can be used with a small flow of (15) running water in areas with heavy dust and smoke. In this case water is directed into the entrance pipe through a small connec0ng pipe. Addi0onally, another pipe starts deep inside the water, extends upward, and exits the container approximately two millimetres above the water's surface, allowing excess dirty water to escape. In situa0ons where full (20) running water is used, the receiving hole in the mixing pipes is excluded. BRIEF DESCRIPTION OF EMBODIMENTS To assist with the understanding the inven0on, references will now be made to the accompanying drawings which show three (3) examples of the inven0on: (25) FIG 1 shows an example of the purifier with two mixing pipes; however, more can be added. FIG 2 shows an example of the purifier with only one mixing pipe. FIG 3 shows an example of the purifier with the exhaust pipe in the middle of the lid and with six, or more, entrance and mixing pipes to draw large (30) quan00es of clean air as the purifier is extra-large. 2025202069 21 Mar 2025 DETAILED DESCRIPTION OF EMBODIMENTS FIG 1 shows the complete purifier, including all opera0onal components. The container (1) is designed in the shape of a bucket. The water level or water surface (2). The lid (3) of the container (1). The entrance pipe (4) (5) which is connected from the centre of the lid (3) and descends downward inside the middle of the container (1) and above the water level / surface (2) separates into two or more pipes, the mixing pipes (6). The exhaust holes (5) or two exhaust pipes (5) on top of the lid (3) and around the entrance pipe (4) allows the clean air to escape out of the purifier. The (10) mixing pipes (6), which may be two or more, extend from the entrance pipe (4) and feature an open curve. A small sec0on of these pipes enters just below the surface of the water (2), but not too deeply. This design helps reduce water pressure and op0mizes airflow for maximum efficiency. The small sec0on of the mixing pipes (6) which sit under the (15) water level (2) has a receiving hole (7) at the base from which the mixing pipes (6) draw the water to be mixed with the air. That small sec0on of the mixing pipes (6) with an open curve (A) rise out of the water surface (2) and travel upwards with more curves (B), (C) and (D), to beAer mix the water with the air, inside the mixing pipes (6) un0l all the air becomes (20) moisturised and finishing at the top interior sec0on of the bowl (9). The separa0on system (8) resembles an upside-down bowl (9) with an extension wall (10). Posi0oned near the mouth (11) is the extension wall (10) which surrounds the bowl (9) with a corner slopping downward and extending towards the walls of the container (1) and ending at the same (25) height as the bowl’s (9) edge. This configura0on creates a narrow gap between the separa0on system (8) and container (1) wall, allowing clean air to flow upward and exit through the exhaust holes (5). Number (12) shows the internal ridge and channel structure within the wall of the bowl (9) that finish at the mouth (11) of the bowl (9). The threads (13) at (30) the top of the container (1) aligns with the corresponding threads (13) on the lid (3), ensuring a secure and air0ght fit when the lid (3) is screwed onto the container (1). For the purifier to operate efficiently, the fan must draw air through a grill with holes smaller than the openings of the mixing pipes (6) and smaller than the openings of the receiving holes (7) to (35) prevent blockages. The air which blows the fan inside the purifier must be 2025202069 21 Mar 2025 the same temperature as the atmospheric air, or a bit cooler, to prevent the water from overhea0ng and producing steam. As the fan blows the air into the entrance pipe (4) the air travels downward into the mixing pipes (6) and forces the water and air to hit the first curve (5) (A) crea0ng a substan0al splash which hits the inside wall of the mixing pipes (6). As the air and the water travel upward, they encounter the second curve (B) and the wall of the mixing pipe (6). The same happens at the third (C) and the fourth curves (D). This process mixes the water into the air above the water surface (2) satura0ng it. Normally the last curve, (10) in this case curve (D), sits inside the bowl (9) and the mixing pipes (6) finishing almost at the top of the bowl (9) with a curve towards the entrance pipe (4) blowing all the moisturised air and hi>ng the top of the bowl (9) and the entrance pipe (4) and the air from the opposite mixing pipe (6) spreading it all over the top of the bowl (9). The first stage of (15) separa0on and filtra0on of the air from the moisture and the dirt, inside the bowl (9), start at this point. All the moisture, together with the humidity and captured dirt from the air, turns to water that falls to the water surface (2) either from the mixing pipes (6) or from the entrance pipe (4). However, most of the water drops down from the channels to the (20) water surface (2) crea0ng lots of bubbles. The second stage of the separa0on of air from moisture and dirt happens underneath the separa0on system (8) and above the water surface (2). The air loses its strength because the bowl (9) is much wider than the entrance pipe (4). The air comes out and down from the mouth (11) of the (25) bowl (9) and hits many wet places, for example, the entrance pipe (4), the mixing pipes (6) and the falling water from the channels and the surface of the water (2) and becomes moisturised again. As the air travels downwards, it gently hits the surface of the water (2) and destroys all the bubbles and the moisture along with the dirt they carry remain in the (30) water. Only the air escapes to the sides and hits the container wall (1) and floats upward. Some air travels down from the mouth (11) of the bowl (9) but does not reach the surface of the water (2), it turns upward but the air from the mouth (11) of the bowl (9) forces that air to hit the wall of the container (1) together with the air underneath. Air travelling up, along (35) with addi0onal air which escape out of the edge of the mouth (11), meet the extension wall (10) forcing all the air to hit the wall of the container 2025202069 21 Mar 2025 (1) for the last 0me. The resul0ng clean air, free of moisture, turns up and out of the space between the extension wall (10) and the container wall (1) and floats up to the exhaust holes (5) and escapes out of the purifier. The air from the mouth (11) of the bowl (9) and the extension wall (10) (5) forces the air to hit the container wall (1) and the remaining moisture and dirt stays there forming small drops which slowly slide to the water surface (2) of the container (1). The arrows indicate the air circula0on inside the purifier. FIG 2 shows a purifier with only one mixing pipe (6). These are more (10) suitable for homes but can be used in larger sizes as well. The entrance pipe (4), which is curved at the base, sits just below the water level (2). This same pipe becomes the mixing pipe (6) and as the air pushes the water, which is always collected from the receiving hole (7), it rises out of the water with a smooth curve (A), travels up and inside the separa0on (15) system (8) with two or more curves (B) and (C). Within the separa0on system (8) the mixing pipe (6) breaks into two smaller curved branches (a) and (b). These hit the top of the inside sec0on of the bowl (9) and the entrance pipe (4) with the moisturised air. From this point onward, it operates in exactly the same manner as the purifier depicted in FIG. 1. (20) FIG 3 illustrates an extra-large purifier capable of drawing large quan00es of clean air with six or more entrance pipes (4) and mixing pipes (6). The container (1) is beAer if it’s shaped like a bucket as its top is wider than the boAom hence allowing for a bigger separa0on system (8) to reduce the air pressure and have perfect air filtra0on and enough space between (25) the extension wall (10) and the wall of the container (1) permi>ng clean air to flow upward and escape out of the purifier. The exhaust pipe (5) is securely aAached to the centre of the lid (3) and extends into the purifier, ending slightly below the lid (3) at the top centre of the separa0on system (8) which is connected firmly. Surrounding the exhaust pipe (5), between (30) the lid (3) and the separa0on system (8), are large holes (15) from which the exhaust pipe (5) draws the clean air. The separa0on system (8) in addi0on to the bowl (9) and its extension wall (10) also includes a dropping pipe (14). The dropping pipe (14) starts from the top centre of the bowl’s (9) interior and extends down to the water 2025202069 21 Mar 2025 surface (2). It is sealed at both ends, top and boAom, and its func0on is to spread the moist air across the upper interior of the bowl (9) while also direc0ng some water back to the water surface (2) during the first stage of the air-moisture separa0on. Number (12) indicates the beginning of the (5) ridge and channel sec0on which end at the mouth (11) of the bowl (9). This design allows the entrance pipes (4) to enter the purifier through the container wall (1) beneath the mouth (11) of the bowl (9) and near the surface of the water (2). The external section of the entrance pipe (4) is encircled by holes (13) that prevent large foreign particles from entering (10) the entrance pipe. To ensure the purifier remains unblocked, these holes must be smaller than the receiving holes (7). As the entrance pipes (4) extend downward inside the purifier, they curve toward the container wall (1) before descending into the water with an open curve. At this stage, these entrance pipes (4) become the mixing (15) pipes (6) with the receiving holes (7) posi0oned underneath and with another open curve (A) exi0ng the water and con0nuing through a series of addi0onal curves (B, C, D, & E) direc0ng the moisturised air to the upper interior of the bowl (9) and into the dropping pipe (14). As the fan draws clean air from the exhaust pipe (5), dirty air enters the purifier through (20) the entrance pipes (4) and flows into the mixing pipes (6) and to the top of the bowl (9). Following this process, the purifier operates in the same manner as the purifier shown in Figure 1. All purifiers including Figures 1, 2 and 3 follow the ocean method of mixing the water into the air and above the water surface (2), ensuring thoroughly dehydrated, clean air (25) ideal for healthy breathing.
Claims
1. My invention is a water-based air filtration system, designed with a container that can be shaped like a bucket or any other form that best (5) serves the intended purpose and includes a clear indication of the water level.
2. The top of the device features a lid that screws securely onto the container, featuring multiple holes to allow the release of clean air from the purifier. At the centre of the lid, the entrance pipe is fixed, (10) serving as the inlet for air, which extends into the middle of the container, to which is connected the rest of the purification system, the mixing pipes and the separation system.
3. The purifier in my invention removes all foreign particles from the air by employing a method that mixes water with the air until the air is(15) fully saturated. This process occurs above the water's surface, similar to the natural purification method found in the oceans.
4. The purifier utilizes a two-stage separation system that effectively removes all moisture, all humidity and all foreign particles from the air, all while operating above the surface of the water.(20) 5. The separation system is located close to the lid and is shaped like an upside-down bowl, with its centre connected to the entrance pipe. Its dimensions vary in length and width, depending on the size of the purifier. The interior is sealed tightly, with the only opening at the bo.om, where the mouth is slightly wider than the top of the bowl.(25) The inner walls taper downward and feature ridges and channels, while the outer surface is smooth. Near the mouth, there is an extension wall that angles toward the container walls, finishing at the same level as the bowl. This design leaves a small gap around the perimeter, allowing the purified air to escape upward through the exhaust holes.(30) 6. The process of mixing water into the air, as described in Claim 3, takes2025202069 21 Mar 2025place within the mixing pipes. These pipes draw water from the receiving hole, and with the aid of their curved design, they ensure that the air becomes fully moisturized before releasing it onto the top interior of the bowl.(5) 7. The first stage of separating the air from moisture and foreign particles,as described in Claim 4, occurs inside the bowl. The moisturized air, blown into the top of the bowl by the mixing pipes, initiates the separation of moisture from the air. The moisture and humidity, along with the dirt particles collected from the air, condense into water and(10) fall downward, flowing through the entrance pipe, mixing pipes, and most of the channels, creating bubbles on the surface of the water. The now clean, moisture-free air exits down from the mouth of the bowl.
8. In the second stage, as described in Claim 4, the air descending from the mouth of the bowl gently contacts the surface of the water,(15) disrupting the bubbles. The air then escapes to the sides and rises, striking the wall of the container. Some of the air that does not reach the water's surface turns upward, colliding with the inner wall of the container, along with the air beneath. As the air rises, it meets the extension wall near the bowl's edge, which redirects the air to make a(20) final impact with the container's wall. Upon striking the wall, any remaining moisture and particles condense into small droplets, which slowly slide back into the water, while the purified air rises and exits the purifier.
9. The purifier separates the air from all the moisture, all the dirt and (25) collects all of the humidity also. The air which comes out of the unit is totally clean and free of foreign particles and dehydrated.
10. In all purifiers, the functional processes occur above the water surface, while the water below the surface remains calm down to the base, except for the water falling from the separation system, which(30) generates bubbles.
11. All my purifiers, regardless of size or the number of mixing pipes, operate in two ways. Air can either be blown into the entrance pipe(s), or clean air can be drawn from the exhaust pipe.2025202069 21 Mar 202512. My purifier will never become clogged if the grill covering the fan that draws the air remains unobstructed. This grill is designed with holes smaller than the openings of the mixing pipes and the receiving holes. Similarly, if clean air is drawn from the exhaust pipe, the entrance(5) pipe(s) must also be equipped with a similar grill.
13. My purifier operates with a small flow of running water that enters through the entrance pipe with an additional pipe attached to its side. This setup is particularly recommended for environments with heavy dust and smoke. An additional pipe, starting from the bottom inside(10) the container, extends upward and protrudes about two millimetres above the water surface, allowing excess dirty water to drain out of the purifier.
14. My purifier can be built from plastic, metal or a combination of both.
