The present invention relates to a vortex spray type steam head device, which includes: a nozzle member having a cylindrical shape, and receiving and spraying steam to the outside; a rotary body rotatably coupled to an upper portion of the nozzle member, having a receiving groove having a predetermined depth on an upper portion thereof, and having a through-hole longitudinally formed through a center portion; a ring-shaped support body inserted in the receiving groove and supporting the rotary body; a fixing bolt fixing the rotary body to the nozzle member with the support body inserted in the receiving groove; and a cover member having an open top, having a receiving space therein, and receiving the nozzle member, the rotary body, the support body, and the fixing bolt therein.

Disclosed is a noise suppressor for use inside a nozzle and adjacent a nozzle liner. The suppressor can include an inlet with a cross-sectional area larger than that of the nozzle liner outlet. The suppressor can also have an entrance length with a diverging cross-sectional area, and an exit length extending from the entrance length. By incorporating this geometry, the noise suppressor reduces noise and improves performance of the apparatus in which the suppressor is used.

A compressed air introduction part (5) capable of introducing compressed air into an air passage (2a) of a cylinder body (2) is provided. The compressed air introduction part (5) has a compressed air exit port (5a) formed in the shape of a ring that extends circumferentially about a cylinder-center axis (C1) of the cylinder body (2). An annular protuberance surface portion (30) is formed on an inner circumferential surface forming the air passage (2a) on an air blowout port (2c) side of the compressed air exit port (5a), and a protuberance surface (30a) of the annular protuberance surface portion (30) is shaped so as to extend from a peripheral edge portion of the air blowout port (2c) side of the compressed air exit port (5a) along the radial direction of the cylinder body (2) and to then gradually curve and extend toward the air blowout port (2c) side.

According to an embodiment of the present invention, a substrate processing apparatus including: a chamber in which a process is performed on a substrate; a susceptor installed in the chamber to support the substrate; and a showerhead installed above the susceptor, and the showerhead includes: a plurality of inner injection holes defined in an inner area corresponding to a portion above the substrate and injecting a reaction gas downward; and a plurality of outer injection holes defined in an outer area corresponding to a portion outside the inner area and injecting an inert gas along an inner wall of the chamber.

Includes an electromechanical device (1), which acts like an electronic catalog for the olfactory testing of different fragrances or aromas, contained in an absorbent cylindrical element (2) inserted into individual cartridges (3), which are interchangeable and encased in a carousel (4), supported on central bearings (5) and radially moved by means of an electric motor (6) with reducer (7) and gearing (8) that acts in a circular rack (9). Upon receiving a command, via application, the carousel (4) turns positioning the cartridge (3), corresponding to the fragrance or aroma chosen, in front of the connector nozzle (10), thanks to a positioning sensor (S), which counts the turns of the shaft of the electric motor (6). Next, a mechanical actuator (11) formed by an electric motor (12), gearing (13) that acts in a straight rack (14), which in turn drives a drawing cane (15), which pushes, and then retracts the cartridge, (3) inside the connector nozzle (10), and jointly with the air flow coming from a flexible hose (16), from where the air inflated by a compressor (17) enters said cartridge (3), forces the emission of the scent by the outlet orifice (18) of the top (19) of the box (20), thus providing the user a reliable olfactory testing.

A sensor apparatus includes a sensor window; a first nozzle adjacent to the sensor window and oriented to blow across the sensor window, the first nozzle positioned below the sensor window and in a first horizontal direction away from the sensor window, the first nozzle being slot-shaped with a first length and a first thickness; and a second nozzle adjacent to the first nozzle and oriented to blow across the sensor window, the second nozzle positioned below the sensor window and in the first horizontal direction away from the sensor window, the second nozzle being slot-shaped with a second length and a second thickness. The second nozzle is farther from the sensor window in the first horizontal direction than the first nozzle, and the first length of the first nozzle is greater than the second length of the second nozzle.

A gas distribution system having a first plurality of apertures to supply a gas source to a reaction chamber and a second plurality of apertures surrounding the first plurality of apertures and configured to remove the gas from the reaction chamber. In one embodiment, the second plurality of apertures may gradually increase in diameter as the distance from a main exhaust channel increases. Alternatively, or in addition, the angle spacing between adjacent apertures may gradually decrease as the distance from the main exhaust channel increases.

A vehicle washing system includes a vehicle treatment area that is configured to receive a vehicle to be dried. At least one dryer media device is positioned in the vehicle treatment area. The at least one dryer media device is configured to dry the vehicle upon contact with the vehicle. An air moving assembly is located adjacent to the at least one dryer media device in the vehicle treatment area, and is configured to remove excess moisture from the at least one dryer media device.

The present disclosure provides a toilet seat assembly for delivering medicine, washing, cleaning, and drying a perineal region of a user. The toilet seat assembly includes a spraying nozzle assembly having one or more retractable spray nozzle units for delivering a liquid product, a drying nozzle assembly having one or more retractable drying nozzle units for drying the region, and a medicine delivery assembly for delivering a medicinal product to the region, the medicine delivery assembly having a medicine delivery nozzle connected to a medicine storage element containing the medicinal product.
