Description

Field of technology to which the utility model belongs

The claimed utility model relates to the field of keeping pets, in particular, to the field of caring for animals at home, namely to the toilet for pets [A01K1/01, A01K29/00].

State of the art

A type of pet litter box is widely known in the form of a tray containing a grate for holding a replaceable aggregate into which the pet urinates and defecates when in use. A space is provided under the grate for receiving animal urine and particles of damaged filler passing through said grate.

However, a mixture of particles of damaged filler and urine is an extremely favorable environment for the reproduction of bacteria that release ammonia during their life, which is the cause of the specific smell of urine.

To improve on the type of pet toilets described above, solutions have been developed in the prior art with a second grate made with a smaller mesh and located below the first grate. The second grid separates part of the damaged filler from the urine, resulting in a mixture with urine, there is a smaller amount of filler particles and the specific smell of urine does not appear as quickly.

In particular, a TOILET FOR TREATMENT OF EXCESS AND URINE [JP 2004194596 A publ. filler, and a lower metal grate configured to hold particles of damaged aggregated filler and pass liquid, wherein the average size of the holes in the lower grate is less than the average size of the holes in the upper grate.

Also known from the prior art is a URINE COLLECTION SET FOR ANIMALS [JP 2020080866 A publ. a grid formed by a liquid-permeable web of sheet material, wherein the average opening size of the bottom grid is smaller than the average size of the openings of the top grid.

Also known from the prior art is a TRAY FOR CAT WC [CN 206866300 U publ. , made with the possibility of retaining particles of damaged aggregated filler and passing liquid, and the average size of the holes of the lower grate is less than the average size of the holes of the upper grate.

A common disadvantage of the above-described known analogues of the claimed utility model is that the upper and lower grates are made adjacent to each other, as a result of which, during the use of the toilet, filler particles soaked in animal urine are collected on the lower grate, which do not dry out in a closed space limited by the body and filler on the upper grate, and form an extremely favorable environment for the growth of bacteria that cause urine odor.

As the closest analogue (prototype) of the claimed utility model, the applicant considers a FILLER SAVING DEVICE [US 5211133 A publ. a grate designed to hold particles of damaged aggregated filler and pass liquid, wherein the average size of the holes of the lower grate is less than the average size of the holes of the upper grate, and the upper and lower grates are removed from each other.

Making the grids at a distance from each other increases the space between the lower and upper grids, in which the filler particles soaked with urine are located, which theoretically should help them dry out and reduce the smell of urine. However, in the prototype (as in the analogues described above), when the filler is placed on top, the body forms a closed space, which, during the use of the toilet by the animal, is saturated with urine vapor, which prevents the wet filler particles from drying out on the lower grate. As a result, these particles form an extremely favorable environment for the reproduction of bacteria, which leads to the formation of a specific smell of urine.

The technical problem to be solved by the claimed utility model is to eliminate the possibility of creating favorable conditions for the growth of bacteria and the creation of a pet toilet that allows the filler particles soaked in urine to dry out.

Disclosure of the essence of the utility model

The technical result of the claimed utility model is the possibility of drying the filler particles soaked in urine.

The specified technical problem is solved, and the specified result is achieved by creating a pet toilet containing an open-top body, in which, at a distance from each other, are placed: particles of damaged aggregated filler and liquid transmission, wherein the average size of the holes of the lower grille is less than the average size of the holes of the upper grille, while ventilation holes are made in the side surface of the housing, below the upper grille.

The presence of ventilation holes in the body, in combination with the implementation of the gratings at a distance from each other, makes it possible to ventilate the interior of the body of the animal toilet and dry the urine-soaked filler particles held on the lower grate, as well as the urine-soaked filler particles that could remain on the upper grate. By drying the urine-soaked filler particles, favorable conditions for bacterial growth are eliminated and substantially eliminate the odor of the animal's urine, which is due to the ammonia produced by the bacteria.

In particular, the distance between the upper and lower gratings is more than 5 mm.

In particular, the upper grille and/or the lower grille are made of stainless steel or plastic.

In particular, the mesh size of the upper grate is 1-6 mm.

In particular, the cell size of the lower grating is 0.08-0.4 mm.

In particular, ventilation holes are made in the side surface of the housing below the lower grille.

Implementation of the utility model

The claimed pet litter box is shown in the drawings exploded and without one of the side walls for illustrative purposes only. All components of the claimed device are interconnected by assembly operations and are in functional and constructive unity.

In this application, a toilet is understood as a sanitary device for receiving urination and defecation products.

In this application, pets are understood as companion animals living with a person in the same room, and trained to send natural needs to the tray, in particular, cats, dogs, rabbits, ferrets, raccoons.

The relative signs "top" and "bottom" (as well as under/above, up/down) correspond to the directions up and down in the accompanying drawings and in the declared pet toilet installed on a horizontal surface.

The claimed toilet for pets contains a housing 1 open from above, in which, at a distance from each other, there are: an upper grate 2, made with the possibility of holding an integral aggregated filler, and a lower grating 3, made with the possibility of holding particles of a damaged aggregated filler and passing liquid, and also drain surface 4, made with a slope and containing at least one drain hole 5.

In the present application, the placement at a distance means placement at a non-zero distance from each other, preferably at a distance of more than 5 mm from each other.

The housing 1 is made of plastic, in particular polymethyl methacrylate, polyethylene, fluoroplastic or polypropylene. These materials do not absorb animal odors and urine, are not subject to corrosion, and therefore do not form an environment favorable for the growth of bacteria, and at the same time have sufficient strength for the use of the toilet by a pet.

In the exemplary embodiment shown in the drawings, the housing 1 has a rectangular shape and has four side walls, however, the housing 1 can also have, for example, an oval, square, round shape. The side surface of the housing 1 wall below the level of the upper grille 2 contains ventilation holes 6, preferably below the level of the lower grille 3. in particular, the lower grille 3.

The upper grate 2 is made of plastic or metal, preferably stainless steel, with a mesh size that allows the retention of intact aggregated filler and the passage of particles of damaged aggregated filler with animal urine, preferably with a mesh size of 1-6 mm.

The upper grate 2 is made removable, that is, with the possibility of being removed from the housing 1, and rests on supports 7 attached to the inner surface of the housing 1. The supports 7 are attached to the inner surface of the housing and provide vertical support for the upper grate 2 and, for example, are made in the form corners, one surface of which is attached to the inner surface of the body 1 or in the form of pins protruding from their body.

In the illustrated embodiment, bead 8 is attached to the upper grate 2 along the perimeter, configured to hold the aggregated filler in space above the upper grate 2. In alternative embodiments, the bead 8 may not be attached to the upper grate and be part of the housing 1. From below to the upper grate 2, at least one stiffening rib 9 is attached (FIG. 2), providing additional support for the upper grille 2 with an increase in its overall structural rigidity of the grille 2. In the embodiment shown in FIG. 2, one longitudinal stiffener is made, however, embodiments are also possible with multiple transverse strength ribs and/or multiple transverse ribs.

Aggregate litter refers to a wicking litter made up of capsules/granules/pellets/flakes that break down into smaller particles during pet use, e.g. wood granular litter, clay litter, corn litter, mineral litter such as bentonite. The size of the filler capsules/granules/pellets/flakes ranges from 2 mm for the smallest fractions of mineral filler to 20 mm for the largest sawdust granules. Thus, the specified range of cell sizes of the upper grid 2 makes it possible to keep essentially all types of aggregated filler in an intact state.

In the present application, the feature "grid 2 or 3 is capable of holding intact/crushed filler" is not limited to the ability of the grate to hold all intact/crushed filler and characterizes the ability to retain most (at least 95%) of intact/crushed filler.

The lower grille 3 is made of plastic or metal, preferably stainless steel, with a mesh size that allows the holding of filler particles and the passage of animal urine, preferably with a mesh size of 0.08-0.4 mm. The lower grille 3 is located on the canopies 10 attached to the inner surface of the housing 1. The lower grille 3 can be attached to the upper grille 2, for example, by means of jumpers, with the formation of a single removable unit. Alternatively, the lower grille 3 can be rigidly fixed to the visors 10.

The Applicant has found that no aggregated filler of the types available on the market produces particles larger than 0.4 mm when damaged. In addition, it was found that the grid is satisfactorily permeable to liquid with a mesh size of 0.08 mm.

Under the grating in this application is understood a surface made with a plurality of through holes, while the grating can have a different size and different shape of the holes - round, square, rhombic, and also have different stiffness and represent, among other things, a grid, that is, a flexible grate .

Grilles 2 and 3 made of plastic or stainless steel do not absorb odors and urine, are resistant to corrosion, and therefore do not form an environment favorable for the growth of bacteria.

The visors 10 are an angular, that is, L-shaped, profile, one of the sides of which is attached to the inner wall of the housing 1. At the same time, the second side of the L-shaped profile forms a horizontal visor that protects the ventilation holes from urine entering them when they are located below the level bottom grid.

Drainage surface 4 shown in the drawings of the exemplary embodiment is made in the form of a plane in the form of essentially a rectangle, one corner of which is located below the rest. In other possible embodiments, the drain surface 4 may be in the form of a substantially funnel. In the exemplary embodiment shown, the drain surface 4 is formed by the bottom of the housing 1, however, embodiments are also possible in which the drain surface 4 is located above the bottom of the housing 1.

Legs 11 are attached to the bottom of the body 1. In the example shown in the drawings, the claimed toilet comprises four legs 11, however, embodiments with three or more than four legs are possible. Preferably, the legs 11 are made with the possibility of height adjustment, for which, in particular, they are made of two parts, movable and fixed relative to each other, for example, connected by a threaded connection.

Under the drain hole 5 of the housing 1 of Figs. 1 and 2, a drain container 12 is placed, configured to collect and accumulate pet urine flowing from the drain hole 5. The drain container 12 is preferably closed from above by a removable lid 13 having a lid opening 14. The hole 14 of the lid in the lid is located under the drain hole 5 in the drain surface 4. Preferably, the area of the hole 14 of the cover is larger than the area of the drain hole 5 by 5-20%. Preferably, opening 14 occupies no more than 20% of the surface area of the lid. An exemplary embodiment is also possible in which the lid is provided with an inclined surface, in the lowest part of which the lid opening 14 is located.

The implementation of the drain container 12 with a lid 13 minimizes the evaporation of the collected urine, and also helps to further reduce the smell of urine.

The drain container 12 is configured to contain an antiseptic and/or disinfectant, such as chlorhexidine or chlorine disinfectants. The drain container 12 can function as an additional leg of the body 1 and function as an additional support.

This feature allows you to create a toilet in which the reproduction of bacteria is completely impossible, which allows, in essence, to completely get rid of the smell of urine.

Alternatively, the drain container 12 may be the lower compartment of the housing 1 and not include a container lid.

It is also possible to implement the claimed toilet, in which the drain container 12 is absent, and the outlet 5 is made with the possibility of connecting to a sewer pipe for draining urine into the sewerage system.

Sides 8, supports 7, visors 10, drain container 12, cover 13 of the drain container and legs 11 are preferably made of plastic, in particular polymethyl methacrylate, polyethylene, PTFE or polypropylene. These materials do not absorb odors and urine, are resistant to corrosion, and therefore do not form an environment favorable for the growth of bacteria.

When using the toilet by an animal, the upper aggregated filler is damaged due to mechanical action from the animal, is impregnated with animal urine, passes through the upper grate 2 and is retained by the lower grate 3. Urine in free form, that is, separately from the filler, passes unhindered both through the upper 2, and the bottom 3 of the grid and flows into the lower part of the body separately from the filler particles.

The presence of ventilation holes 6 in the side surface of the body ensures air exchange of the inner space of the tray and the external environment and air circulation through the grids 2 and 3, which leads to the evaporation of liquid from the surface of the filler soaked with urine and ensures its drying.

As a direct consequence of the possibility of drying out of the urine-soaked filler, the technical effect of reducing urine odor is unexpected. Indeed, it is counterintuitive that the possibility of urine vapor exiting the toilet does not increase the odor, but, on the contrary, reduces it. In order to ascertain this, the Applicant conducted an experiment in which Toilet A was made, corresponding to the embodiment shown in FIG. And the lack of ventilation holes and the lack of a drain hole with a container. The toilets were filled with the same amount of sawdust wood filler. Each toilet was used by the same cat for two days, performing an equal number of urination acts per day. Each toilet would be installed in the same closed room measuring 2×2 m. For each toilet, after three days, the ammonia content was measured using a SIGNAL-4E gas analyzer at a distance of 5 cm from the upper grate for the filler. At the same time, after measurements, the applicant studied the state of the filler trapped in the lower grate of toilets A, B and C. The results of the experiment are summarized in Table 1.
