FR3070822B1 - REMOVABLE DEVICE FOR ASPIRATING AND FILTERING THE BAD ODORS OF A CAT LITTER - Google Patents

Abstract

The invention relates to a device for vacuuming and filtering the bad odors of a litter produced by the excrement of an animal avoiding the spread of these in the house. It consists of a first housing (1) in which there are two compartments (2, 3) into which is introduced into the first (3) a fan (4) which sucks unpleasant odors excrement and clean air to direct them in the second compartment (2) where there is activated carbon granules (5) which filters the bad smells. Once filtered, the remaining odors pass through a pipe (6) which opens onto a second housing (7) and which arrive in the compartment (8) in which it finds an active carbon filter (9) where they are filtered thanks to this one. Once filtered, the air returns to the litter. The device according to the invention is particularly intended for individuals with a litter box. It can also be mounted in series during the manufacture of the litter at the factory.

Description

The present invention consists in sucking and filtering the bad odors of a litter produced by the excrement of an animal avoid the spread of these in the house.

Cat litter boxes are traditionally designed without effective filtration means which is troublesome when the animal is needed. The smell of its excrement spreads throughout the room and disturbs considerably.

The device according to the invention overcomes this disadvantage. It comprises indeed according to a first characteristic a housing in which it finds a fan of twelve volts which it aspires bad smells in the leaders in a compartment in which it finds charcoal pellets. At the exit of this compartment, the remaining odors are directed into a pipe quirepart in the litter and where it finds at its output a second housing equipped with an active carbon filter.

According to particular embodiments: - The mesh is not too small to filter well and not too large not to pass through the activated carbon pellets and it is attached to the housing. - The first compartment of the housing has four edges one at each corner to allow the fixing of the fan. - The second housing has four edges one at each corner to allow the attachment of the active carbon filter. - the two housings are connected with a flexible hose long enough to fit on as many litter box models as possible.

The attached drawing illustrates the invention:

Figure 1 shows in section, the device of the invention.

FIG. 2 is an overall view of the location of the device on the litter, the role and the path taken by the clean air (16), the dirty air (15) and the filtered air (17).

Referring to these drawings, the device comprises a first housing (1) that is fixed above the litter box (14) on the input side, in this housing there are two compartments (2,3) in whichon introduced in the first (3) a fan (4) with a voltage of twelve volts maximum, powered by a USB cable that can connect to any USB port or a sector of an input voltage of two hundred and twenty volts alternative and a maximum output voltage of twelve voltscontinu. The fan draws unpleasant odors (15) from excrement and clean air (16) into the second compartment (2) where there is granular activated carbon (5) which filters odors (15). Once filtered, the remaining odors pass through a hose (6) which opens onto a second housing (7) which is attached to the top of the rear litter pan (14). Odorsrestantes arrive in the compartment (8) in which it finds an active carbon filter (9) where they are filtered through it. Once filtered, the air (17) goes back into the litter thus allowing to renew the air inside and to be again sucked by the fan (4) which constitutes a closed circuit.

The device thus written allows that the smell of feces (15) does not come out of the litter box (14) and avoiding the spread of it throughout the room of the house. Also avoiding the inconvenience of the smell when you come home from work in the evening.

According to a variant not illustrated, it is possible to integrate a device for switching off the power supply and a voltage variator enabling the speed of rotation of the fan (4) to be controlled, thereby affecting the suction flow rate thereof.

The device according to the invention is particularly intended for individuals with a ferry bed. It can also be mounted in series during the manufacture of the litter at the factory.

Claims (5)

1) The device for sucking and filtering the bad odors of a litter produced by the excrements of an animal, characterized in that it comprises a first housing (1) in which it finds two compartments (2,3) into which one introduces in the first (3) a fan (4) and in the second (2) granulated activated carbon (5) followed by an elbow pipe (6) which goes to a second housing (7) provided with a compartment (8) where it finds an active carbon filter (9). 2) Device according to claim 1 characterized in that the mesh (10) is not too small to filter well and not too large not to pass through the activated carbon engranulés (5) and that it is integral with the housing ( 1). 3) Device according to claim 1 characterized in that the first compartment (3) of the housing (1) has four flanges (11) one at each corner to allow the attachment of the fan (4). 4) Device according to claim 1 characterized in that the second housing (7) comprises four edges (12) one at each corner to allow the attachment of the active carbon filter (9) in the compartment (8). 5) Device according to claim 1 characterized in that the two housings (1,7) are connected witha hose (6) long enough to fit on the largest number of possible litter tray model.
