Cartridge for fragrance dispensing device and fragrance dispensing device

Abstract

The invention relates to a cartridge (1) for a fragrance dispensing device (20), comprising a hollow body (2) having an inlet (3) and an outlet (4), and means (7) for accumulating at least one odorant composition, which are arranged in the hollow body (2). According to the invention, the cartridge further comprises closing means (5) for closing the inlet (3) and the outlet (4) and airtight in the closed position. The invention also relates to a device (20) for dispensing fragrances, having a housing and comprising: at least two receptacles (22), each of which is adapted to receive, in a removable manner, a cartridge according to the invention and comprises inlet means (26) and exhaust means (27) of an air flow, which are connected respectively to the inlet and the outlet of the cartridge and are adapted to act on the closing means of the cartridge located in the receptacle so as to move them in the open position; air flow generating means (31) which are adapted to at least generate an air flow passing through the receptacles between the inlet means and exhaust means; and a control unit U which is capable of controlling the air flow generating means (31) as well as the inlet means and exhaust means and is adapted to ensure an independent or simultaneous dispensing of the odorant compositions contained in the cartridges in variable proportions and a closure of the cartridges when the apparatus is stopped.

Description

technical field [0001] The present invention relates to the technical field of fragrance (aroma) diffusion (distribution) equipment, in particular to a diffuser comprising a fragrance or odor cartridge. The invention also relates to a cartridge for a fragrance diffusion device. Background technique [0002] In the aforementioned field, dry fragrance diffusers are known which comprise a cartridge removably mounted in the diffuser, the cartridge being adapted to release at least one fragrance. [0003] For example, document WO 2016 / 098114 discloses a fragrance diffusion system comprising a housing with compartments open to the air, each compartment intended to receive a cartridge containing a fragrance. According to this document, each cartridge consists of a cylindrical hollow body containing a fragrance container, the top and bottom surfaces of which are perforated to allow the passage of air flow in contact with the container. Each compartment is also associated with a fa...

Problems solved by technology

[0004] This system allows for the diffusion of fragrance while being easy to use, but in particular has the disadvantage that the container of each cartridge is always in contact with the ambient air, so even when used with Fragrance diffuses permanently even when the fan associated with the cartridge is stopped or the device is completely stopped

This results in an uncontrolled discharge of the cartridge container and makes it impossible to provide a fragrance composition that does not contain the fragrance of a cartridge that diffuses the fragrance ingredients it contains even if the associated fan is stopped
