Reference is now made to Figure 1, which shows a side view of a filter cartridge 100 for the removal of malodors, for example due to animal waste, according to one embodiment of the present invention.

This figure shows a filter cartridge 100, for example for removing odors caused by animal excrement, comprising a liquid reservoir 101 and a pump 102 connected to the liquid reservoir 101 by at least two tubes 103, 104. It clearly shows that it is included. In this example, filter cartridge 100 is removable and open. Filter cartridge 100 may also be integrated with a device requiring malodorous air treatment, such as a pet litter box, for example. Liquid reservoir 101 contains liquid reagents. The liquid reagent may be water. The liquid reservoir 101 may serve as a nutrient source for plants. The filter cartridge 100 is disposed in one tube 103 and includes an air inlet 105 connected to an air injection valve 106 connected to the pump 102. The air injection valve 106 may be a venturi injector that creates low pressure on one side of the venturi when liquid reagents are pumped. The air inlet 105 is connected to the low pressure/suction side of the venturi 106. The tube 103 containing the air injection valve 106 includes a one-way valve 107 at its junction with the liquid reservoir 101. Filter cartridge 100 is configured to regulate air circulation and, in the embodiment shown in Figure 1, includes a presence sensor 109. A presence sensor 109 is connected to a printed circuit board (PCB) 108, resides within the filter cartridge, and is configured, among other things, to control a pump circulating the liquid reagent (see below). The presence detector 109 may be a sensor 110 selected from a motion detection sensor or an IR display sensor. Sensor 110 is also programmable. PCB 108 may be powered by an electrical network or any type of battery. PCB 108 may also supply power to pump 102. PCB 108 may also be a transformer. A light source 111, for example a lamp, LED or similar, may be provided inside the wall of the pet toilet 200, which, if desired, may also be connected to a presence detector 109, possibly If so, it may be programmable to control the switch on and off. The light source 111 may be powered by the PCB 108.

Reference is now made to FIG. 2 which shows an isometric longitudinal cross-sectional view of a pet toilet 200 including a filter cartridge 100 for removing malodors due to animal waste, according to one embodiment of the present invention. This figure clearly shows that the pet toilet 200 includes a filter cartridge 100. In this example, the filter cartridge 100 is removable and open and also includes a liquid reservoir 101. The filter cartridge 100 further comprises an additional filter 112 , which may be a carbon filter, disposed above the liquid reservoir 101 downstream of the air flow direction indicated by the arrow in FIG. 2 . Filter cartridge 100 further includes a PCB 108. The wall of the pet toilet 200 can be made to be light-shielding or opaque, for example, by constructing the wall of the pet toilet 200 with wood, diffusely transparent plastic, or the like. This has the advantage of providing sufficient privacy for the animal when using the pet toilet 200.

It is clear that the pet toilet 200 according to the present invention can be used by various species of animals, and the size of the pet toilet 200 can be adjusted to fit the animal that will use the pet toilet 200. do. Accordingly, an embodiment of the present invention provides for use by animals of a pet litter box comprising a filter cartridge according to the present invention.

A method for cleaning malodorous air within, for example, a pet toilet 200 is also shown in Figure 2 and is performed as follows. Pump 102 is turned on using sensor 110 or according to a user schedule. Water circulation begins using the pump 102. Air is sucked in from the pet toilet 200 using the air injection valve 106, preferably from the base (lower part) of the pet toilet through the air inlet 105. Air from the pet litter box (200) is mixed with the liquid reagent from the liquid reservoir (101) using the air injection valve (106). The purified air is discharged from the liquid reservoir 101 into the environment through an evaporation process. Pump 102 is turned off using sensor 110 or on a user schedule. The direction of air movement inside the pet toilet is indicated by arrows in Figure 2.

One of the advantages of the present invention is that the liquid reservoir and filter cartridge 100 shown in Figure 1 can be used as fertilizer for plants, where the liquid reservoir 101 becomes a source of nutrients, for example by being integrated with a planter. .

Figure 3 shows a schematic side perspective view of a pet toilet including a filter cartridge for removing odor caused by animal waste according to an embodiment of the present invention. This figure clearly shows that the pet toilet 200 includes a planter 201 integrated with the filter cartridge 100 shown in FIG. 1 . The pet toilet 200 may be integrated with the planter 201 or installed adjacent to it. The liquid reservoir 101 of the filter cartridge serves as a nutrient source for the plants in this example.

In this embodiment, where the filter cartridge and optionally the pet litter box are part of the plant, the removal of odors due to animal waste is carried out as follows. Air is sucked from the pet toilet 200 into the filter cartridge 100 according to the present invention as shown in FIG. 1, and nitrogen (N), potassium (K) and phosphorus (P) are extracted by the liquid reagent in the liquid reservoir. ) Adsorption of odors rich in odors is achieved. Because the plant nutrients are enriched, it is an advantage of the present invention to integrate the filter cartridge 100 with the planter 201, where the liquid reservoir acts as a nutrient source for the soil and plants placed in the planter 201. . Integration of filter cartridge 100 can be configured to use a water bridge system or hydroponics. Integration into the plant prevents saturation of the liquid reagent as odor is consumed, and only the level of the liquid reservoir needs to be monitored.

When the integration of the filter cartridge 100 shown in FIG. 1 is configured to use a water bridge system, the filter cartridge 100 is integrated with the planter 201 using the parting surface 202 . The position of the dividing surface 202 can also be adjusted depending on the plant species. If an adjustable split surface (202) is used, the split surface (202) must be sufficiently secured to the wall of the pet litter box (200) to prevent planter soil from falling into the liquid reservoir (101). It should be taken into account that the planter 201 using should be strong enough to support the (wet) planter soil and plants. Using a water bridge system, the soil and liquid reservoirs 101 are completely separated and layered on top of each other. A water bridge is a piece of fabric that contacts the liquid below on one side and the soil in the upper reservoir on the other side. The liquid is lifted by the capillary effect.

There are three options for water bridge systems: The first is a mat system where the mat carries the liquid, the second is where a wick acts as a wick, and the third is where the wick is replaced by granules. To visually represent the system with a water bridge, two examples were studied where the pet toilet 200 extends horizontally and vertically inside the planter. The horizontal expansion of the pet toilet 200 is illustrated in FIG. 3 . In this example, the soil-liquid solution is controllable. In some embodiments, according to the present invention, the soil-liquid solution may have a 2:1 ratio or a 4:1 ratio. The ratio varies depending on the plant species and can be adjusted depending on the position of the dividing surface 202. In this example, the soil-liquid solution ratio is 2:1.

Figure 4 shows a front perspective view of a filter cartridge for removing malodor caused by animal excrement according to one embodiment of the present invention. This drawing clearly shows the vertical expansion of the pet toilet 200. In this example, a vertical extension of the pet toilet 200 is used, and the planter 201 and the liquid reservoir 101 are placed on top of the pet toilet 200 to preserve the original space. The relatively large surface area of the proposed planter 201 may present difficulties in terms of uniform distribution of liquid, preferably liquid that serves as nutrient water, in the planter soil. This is why a mat system is used, with a mat 203 on which the soil is placed. The soil may be planter soil. Any doubts about the ability of these mats 203 to provide sufficient moisture to the deeper layers of the planter soil can be resolved with the help of so-called “pylons” 204. These pylons 204 are cylinders of porous material that vertically connect the liquid reservoir 101 with the shallowest part of the planter soil. For example, pylon 204 may be formed of a porous material such as fiberglass wool surrounded by a cylindrical plastic structure with slots to allow liquid transfer. This may be a mat-wick combination system. Figure 4 also shows a water level indicator (flagpole) 205 when the liquid reservoir 101 is opaque. Other options may be placed on the sides of the liquid reservoir 101.

Figure 5 shows a side view of a filter cartridge for removing malodor caused by animal excrement according to one embodiment of the present invention. This figure clearly shows that in this embodiment the integration of the filter cartridge 100 shown in Figure 1 is configured for use in hydroponics. In this example, filter cartridge 100 is integrated with planter 201 using a perforated separator plate 206. A perforated separator plate 206 is placed on top of a liquid reservoir 101 filled with a liquid reagent, preferably nutrient-rich water. Each hole of the perforated separator plate 206 includes a plate 207. The plants are held in hydroponic growing medium within dish 207. The plant's roots are placed in nutrient-rich water. Liquid reservoir 101 may also include an air pump and an air stone to enrich the water with oxygen.

If the liquid reservoir is configured to serve as a nutrient source for the plant, it has been found that the need for regular replacement of filter cartridges is significantly reduced. As a result of analyzing the odor caused by animal excrement, it was confirmed that the main volatile components are composed of thiol, ammonia, and pyruvic acid, of which ammonia is the main component. To test the durability of the liquid reservoir when used as a plant nutrient, an experiment was performed to monitor two parameters over time.

Absorption of volatile components in water is expected to affect pH, and since ammonia is the main component, increasing ammonia concentration will make it more basic and thus increase pH. In addition to pH, ammonia concentration was also measured over time. As can be seen in Figure 6, pH increased only slightly over the 27-day test period, and ammonia concentrations began to increase from day 20, but were well below the values of approximately 200 to 300 mg/L found in liquid fertilizers.
