Provided are a bubble generation apparatus and a washing device, the bubble generation apparatus includes a gas dissolution chamber, a bypass member, and a bubbler. The gas dissolution chamber has a vent opening, a liquid inlet, and a liquid outlet, the bypass member has a gradually contracting section, a throat part, and a gradually expanding section which are connected in sequence from a bypass inlet to a bypass outlet; the bubbler is connected to the liquid outlet, the bypass inlet or bypass outlet of the bypass member is connected to the liquid inlet to supply liquid into the gas dissolution chamber, and the throat part is connected to the vent opening or a gas storage space in the gas dissolution chamber.

The present invention discloses a flame simulating device, comprising a mist generating chamber, an atomizing head, an air orifice and a nozzle. The inside of the mist generating chamber is provided with a liquid and the atomizing head, the atomizing head being capable of atomizing the liquid inside the mist generating chamber, the two sides of the nozzle being set as Coanda curved surfaces, the cross section of the air orifice being in a constricted shape and providing an air flow blown upward such that under the Venturi effect, the air flow blown upward will guide and attract the mist from inside the mist generating chamber to vent out and flow into a nozzle inlet; the upper surface of the mist generating chamber is provided with a breathing port, and the breathing port directly faces the atomizing head. Due to the Coanda curved surface on the side of the nozzle, the mist flows along both sides of the nozzle under the Coanda effect and then vents out of the nozzle.

A device and to a process which can be carried out using the device, for the production of fine particles from a liquid which solidifies upon cooling, in particular from liquid fat. The process has the advantage of producing fine particles of very small size, preferably with narrow size distribution. The device has the advantage that a solidifying liquid can be supplied at a temperature above its solidification temperature, without cooling gas leading to solidification of the liquid in the supply line, which cooling gas is used in the production of the particles.

An air amplifier utilizes a high-pressure input stream of air to accelerate a low-velocity input stream of air to provide a high-velocity, high-volume output stream of air. A coupled air amplifier array includes multiple air amplifiers which couple their respective output streams of air to one another to form a single collective output stream of air. Multiple coupled air amplifier arrays can be utilized to form coupled air amplifier array systems to provide multiple collective output streams of air which can be focused toward to an audience within a venue. The coupled air amplifier array system can be implemented within atmospheric effects systems to provide atmospheric effects, such as wind, scent, and/or temperature to provide some examples, relating to an event. These atmospheric effects systems can present these atmospheric effects to the audience to enhance the immersion of the audience as they are viewing the event. These atmospheric effects systems can include multiple portable mobile effects pods that are situated within different locations within the venue to present these atmospheric effects to different locations with the venue.

A handheld digital nebulizer device and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The handheld digital nebulizer device includes a housing having an exhalation valve, a reservoir, an ejector mechanism, and at least one differential pressure sensor. The handheld digital nebulizer device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The handheld digital nebulizer device is then actuated to generate a plume of droplets having an average ejected particle diameter within the respirable size range, e.g, less than about 5-6 μm, so as to target the pulmonary system of the user.

A trigger sprayer is described which utilizes a ball valve to control the flow of a carrier fluid such as water. The ball valve is actuated by a trigger which is biases to the open position by a torsion spring. Provision is made for the trigger sprayer to draw a chemical solution from a supply container and meter it through one or more outlet devices for providing streams in the form of fan or mist sprays, or other shaped sprays.

A pressure washer includes a motor configured to drive a pump, a frame having first and second end portions, a handle having first and second end portions, and a rotating joint rotatably coupling the first end portion of the handle to the second end portion of the frame. The rotating joint includes a locking mechanism to selectively lock the position of the handle relative to the frame. The handle rotates between a storage position and an extended position. In the storage position, the second end portion of the handle is positioned near the first end portion of the frame such that the motor and the pump are located within a volume defined by the first and second end portions of the handle and the frame. In the extended position, the second end portion of the handle is spaced apart from the frame.

A single-dose cartridge inhaler comprises a dosing chamber configured to contain dry powder medicament, a transducer and a controller electrically coupled to the transducer. The medicament delivery device is capable of delivering a therapeutically effective dose of dry powder medicament in response to between 2-20 tidal inhalations, the dose preferably having a mass median aerodynamic diameter (MMAD) of about 6 microns or less and a fine particle fraction of at least 30%.
