Abstract:
PROBLEM TO BE SOLVED: To provide a mist generator, capable of efficiently generating mist even in a case where the supply flow rate of a liquid to be made to mist is low due to a low supply pressure thereof. SOLUTION: Supply hot water 4 is supplied downward from a hot water supply pipe 3 within a sauna device body 2 set in the ceiling surface of a bathroom 1, and air compressed by an air pump 5 is swiftly injected through air nozzles 7a and 7b. The supply hot water 4 is adjusted to a low flow rate of about 0.03-0.1 l/min, and the injection flow rate of air jets 9a and 9b is adjusted to a flow velocity relatively high, compared with the falling flow velocity of the supply hot water 4. The air jets 9a and 9b with the relatively high flow velocity collide with the supply hot water 4, and the supply hot water 4 is thereby finely crushed to generate mist 10. The generated mist 10 is mixed with air circulated by a fan motor 8, and diffused evenly within the bathroom 1, and the diffused mist 10 raises the temperature and humidity within the bathroom 1, providing a high-temperature, high-humidity sauna space.

Abstract in simplified Chinese:一种产生一雾状流体流以施加一大致均匀之雾状流体镀层至一表面之设备与方法,譬如使用于电路板的一种液体熔剂镀层。一个喷射一圆锥形雾化状态之雾状流体之超音波喷雾器,以及一个导气角,喷射一与该雾状流体流路径相交之空气流,并将该雾状流体流夹带于空气流中。二个彼此位于该超音波喷雾器二对边之空气喷口,每一空气喷口喷射出一彼此方向相反之低压空气喷流。而每一空气喷流将圆锥形雾化状态之雾状流体分别剪切成一雾状流体卷流。然后此二雾状流体卷流会被由导气角所喷射出之一片移动空气所夹带,因此形成一大致均匀线性分散之雾状流体,并以此雾状流体镀敷一表面。
Abstract:
A delivery nozzle for aerosol and solvent includes a nozzle body defining an aerosol passage and a solvent passage therethrough. The aerosol and solvent passages each extend from an inlet end of the nozzle body to an outlet end thereof. The nozzle body can include a solid, unitary structure with the aerosol and solvent passages both defined through the solid, unitary structure. The inlet end of the nozzle body can include a mounting flange configured to mount the nozzle body in a device for delivering aerosol through the aerosol passage and for delivering solvent through the solvent passage. The solvent passage can define a smaller cross-sectional flow area than that of the aerosol passage.
Abstract:
A laminated nozzle assembly is provided. The laminated nozzle includes a first end plate having a first fluid inlet and a second fluid inlet, a second end plate, a plurality of nozzle plates positioned and clamped between the first end plate and the second end plate, a first fluid conduit in fluid communication with the first fluid inlet formed in one or more of the nozzle plates, a second fluid conduit in fluid communication with the second fluid inlet formed in one or more of the nozzle plates, a first orifice in fluid communication with the first fluid conduit formed in one of the nozzle plates, and a second orifice in fluid communication with the second fluid conduit formed in the same nozzle plate as the first orifice. The laminated nozzle assembly minimizes the number of nozzle plates and includes no more than eight, and preferably no more than five nozzle plates.
Abstract:
A film forming apparatus includes a spray nozzle, a first chamber, a first gas supply port, a second chamber, a through hole, and a mist outlet. A solution transformed into droplets that is to be sprayed from the spray nozzle is housed in the first chamber and transformed into a mist in the first chamber by gas injected from the first gas supply port. The solution in mist form moves from the first chamber through the through hole to the second chamber and is misted onto a substrate from the mist outlet of the second chamber.
Abstract:
Apparatus and methods are configured to coat a medical device, such as a stent, with a beneficial medicinal agent using one or more liquid feeds and one or more micromist nozzles. In one implementation, an agent coating rig includes a vertical adjustment means, a rotation means, and a traverse adjustment means for moving a medical device along virtually any point on an x or y axis. In additional or alternative implementations, the agent coating rig can further include a secondary horizontal adjustment means that allows adjustment along virtually any point on a z axis. Furthermore, methods and apparatus are provided for distributing the beneficial agent on the medical device, including delivering the beneficial agent efficiently over time.
