    摘要: A spray head (10) for a device for dispensing a fluid product, comprising a body (11) provided with a spray hole (12), the spray head (10) comprising a connecting member (15) rigidly attached to the body (11), the connecting member (15) defining a central axial channel (16), the spray head (10) comprising at least one valve (20; 40) forming precompression means for generating a calibrated spray through the spray hole (12), an intermediate member (14) being inserted between the connecting member (15) and the body (11), the intermediate member (14) being hollow and comprising an opening (14′) that opens into the connecting member (15), a sleeve (40) being mounted so as to slide in the connecting member (15) around the intermediate member (14) between an open position and a closed position, a resilient element (41) biasing the sleeve (14) to its closed position in which it closes off the opening (14′), the sleeve (40) being moved towards its open position when the flow of fluid product (F) is actuated based on a predetermined pressure.

    摘要: A nebulizing device (100) is provided, including: a hollow housing (101), including a cavity (110). where the cavity (110) includes a liquid channel (111) located inside the cavity and a nebulizing spray nozzle (103) located at a distal end of the liquid channel (111) with a plurality of fluid outlets; and an injector (102), at least partially accommodated in the cavity (110). The injector (102) includes: a reservoir (120), configured to accommodate liquid; a liquid conveying pipe (121) including a liquid inlet (122) and a liquid outlet (123), where the liquid inlet (122) is located in the reservoir (120), the liquid outlet (123) is located in the liquid channel (111), the liquid outlet and the nebulizing spray nozzle (103) jointly define a liquid chamber (124), and the liquid conveying pipe (121) is configured to convey the liquid in the reservoir (120) into the liquid chamber (124); and an injector proximal end (102), which is coupled to the liquid conveying pipe (121) and configured to receive a pushing force, so that the liquid conveying pipe (121) is movable in the cavity (110) from a proximal position to a distal position to form a predetermined nebulizing pressure at the nebulizing spray nozzle (103), and the liquid can flow out through the nebulizing spray nozzle (103) and converge to generate a plume spray with a predetermined initial speed, where at least 50% of droplets in the plume spray have an average particle size ranging from 1 um to 10 um.
