A sprayer includes a spray gun and a hopper. An air source provides compressed air to the sprayer to both eject fluid from the spray gun as a spray and to pressurize the hopper. The spray gun includes passages for providing compressed air to the nozzle for spraying and to the hopper for pressurizing the hopper. The spray gun further includes a relief valve for venting pressurized air from the hopper. The hopper receives the compressed air through a port in the hopper, and the compressed air assists the flow of material out of the hopper and into the spray gun.

A portable apparatus for dispensing and foaming of a product, including: a product container which contains a product that is to be foamed by and dispensed from the apparatus; a gas container, at least containing a gas, for example a single gas or a gas mixture, wherein the gas substantially does not contain any greenhouse gases such as N20; a dispersion device, having a product entrance that is connectable to the product container for receiving product, the dispersion device further being connectable to the gas container for supplying the gas to the product during product discharge; a processing device downstream of the dispersion device for performing a mixing treatment and/or pressure reduction on the product provided with the gas; and a product dispensing head, being part of a top section of the apparatus and being arranged downstream of the processing device.

The present invention relates to a liquid chemical sprayer includes: a nozzle cap which is rotatably assembled and installed in place at a rotation guide of a body; a nozzle head; a nozzle is formed at a front end of a nozzle pipe formed extending a predetermined length toward the front, and a guide plate is formed protruding to be assembled to a guide rail formed at a neck capable of operating forward and backward; a valve body formed in a cylindrical shape; a valve housing formed in a cylindrical structure fixedly installed at a rear of the nozzle head and forming a valve seat at an inner portion; and a motor housing faced and assembled with the rear of the valve housing so that the rear thereof is maintained in a fixed state, in which an air blowing module is installed.

The invention relates to a dispensing device (11) for spraying a sprayable medium, in particular a fluid or powder, which device is designed as a handheld apparatus, in which a compressed air device (86) is provided, comprising a spray head (14) that is connected to the housing (12) and is intended for dispensing the medium, comprising a fluid line (44) leading from the storage container (41) to the spray head (14) and comprising a supply line (36) leading from the compressed air device (86) to the spray head (14), and comprising a first nozzle (38) that is connected to the supply line (36) and, separately therefrom, comprising a second nozzle (46) that is connected to the fluid line (44) and that protrudes into an airflow emerging from the first nozzle (38), such that an atomizing zone (49) is formed outside of the spray head (14), wherein, in a plan view of the outlet opening (83) of the first nozzle (38), the second nozzle (46) covers at least 1% of an internal cross section of the first nozzle (38).

The disclosure concerns a spray bottle assembly for use with an atomized-spray dispensing device. The spray bottle assembly generally includes a bottle containing an amount of cosmetic composition, a release mechanism having a port associated therewith, an insert with an insert lumen configured to engage the port for communicating the cosmetic composition therethrough, a nozzle for configuring a stream of the cosmetic composition expelled from the spray bottle assembly, a mixing chamber for mixing compressed air with the stream of the cosmetic composition, and a spray aperture for communicating atomized spray. The spray bottle assembly is designed for use with equipment having corresponding release elements for engaging the insert and release mechanism of the bottle.

A device or system is provided that provides olfactory stimuli, and includes a piezoelectric vibration device that is used to produce scents corresponding to actions performed in a VR or AR environment, or other application. In some implementations, a user interacts with one or more game elements within a game program being executed by a game engine, and responsive to the interaction, the game engine may communicate a series of commands that cause a piezoelectric device of the device to generate scents to be experienced by the user.

A portable apparatus for dispensing and foaming of a product, including: a product container which contains a product that is to be foamed by and dispensed from the apparatus; a gas container, at least containing a gas, for example a single gas or a gas mixture, wherein the gas substantially does not contain any greenhouse gases such as N.sub.2O; a dispersion device, having a product entrance that is connectable to the product container for receiving product, the dispersion device further being connectable to the gas container for supplying the gas to the product during product discharge; a processing device downstream of the dispersion device for performing a mixing treatment and/or pressure reduction on the product provided with the gas; and a product dispensing head, being part of a top section of the apparatus and being arranged downstream of the processing device.

A spray gun includes a machine body, a gun body and a spray cup. A motor is provided in the machine body. A gas exhaust port and a gas intake port communicating with the gun body are provided on a gas outlet passage on the motor. A pressure relief valve is provided at the gas exhaust port and comprises a valve body having a valve cavity. A valve port, a pressure relief port and a mount port communicating with the valve cavity are provided on the valve body. A valve stem and a valve ball rotatable along the valve cavity are provided in the valve cavity. A valve stem spring is provided in the valve cavity to control opening and closing of the gas exhaust port. A gas outlet port is provided on the gas outlet passage. A pressure port is provided on the valve body and communicates with the valve cavity and the gas outlet port.

A wireless charging air compressor includes a housing having a motor operably connected to an air pump, which forces air into a cavity, and an actuator operably connected to the cavity for selectively discharging air through a nozzle secured to the housing. A rechargeable battery is operably connected to the motor for providing power to the motor. A wireless charging receiver mechanism is operably connected to the rechargeable battery. The wireless charging receiver mechanism is configured to recharge the rechargeable battery upon interacting with a wireless charging transmission mechanism. This allow the rechargeable battery to be recharged without the need for a hardwired connection.

A system and method for dermal spraying includes a portable, hand-held dermal application device with one or more disposable cartridges that spray a dermal formulation onto the skin, the disposable cartridge having a nozzle that can be activated by placing the cartridge into the spray device.
