Title: COMPACT VAPORISING DEVICE, AND VAPORISING ASSEMBLY COMPRISING SUCH A DEVICE
Abstract:
This vaporising device comprises a tank (60) for receiving liquid, a piezoelectric element (30), a vaporisation chamber (20) comprising means for generating a mist of droplets (J) and at least one channel (22) for diffusing mist outside of said device (1), the air and the jet of droplets flowing, in operation, in the same direction, from the arrival means towards the diffusion means. According to the invention, the device comprises at least one of the following features: i. the cross-section (d21) of each diffusion orifice (21) is between 3 and 15 millimetres, ii. the height (H23) of the conduit for diffusing drops, linking the admission means (82) and the diffusion channels (22), is between 4 and 20 millimetres, iii. the ratio (S82/S21), between the surface area for admission of air into the chamber and the sum of the surface areas of the various diffusion orifices (21), is greater than 1, iv. the length (L20) of the vaporisation chamber (20) is in the range between 30 and 160 millimetres, whereas the width (l20) of the vaporisation chamber (20) is between 16 and 60 millimetres.
