A spray-gun apparatus, comprising a spray-gun handle, a spray-gun tube-body, and a connection adapter; wherein the connection adapter is connected between the spray-gun handle and the spray-gun tube-body; wherein the first conduction tube is connected with the spray-gun handle and the spray-gun tube-body to use as a gas output path, and the second conduction tube is connected with a second cover-body to use as a gas suction path. Thereby, the gas sent from the spray-gun handle is blown out through the first conduction tube of the connection adapter and the spray-gun tube-body, and the water-sucking tube set inside the spray-gun tube-body will be made to spray liquid; and the second conduction tube of the connection adapter is used to connect a gas suction apparatus, so that the gas around the second conduction tube can be sucked into through the second conduction tube of the connection adapter.

Particular aspects provide novel atomizers for generating particles over a broad range of MMAD size distributions, the eliminating the requirement for an impaction baffle in generating the desired particle sizes. In particular aspects, the atomization means communicates with a remote particle filter member configured and positioned to provide for particle size filtering. In additional aspects, the atomization means communicates with a particle dispersion chamber suitable to impart a desired particle flow pattern to particles within and exiting the dispersion chamber. In further aspects, the atomization means communicates with a nasal, ocular, oral or vicinity adapter. The novel devices provide for targeted (e.g., nasal, ocular, oral, local vicinity), systemic, and/or topical delivery of an atomized liquid (e.g., via the nasal cavity, olfactory region, and mouth). Further exemplary aspects relate to aerosolization and delivery of perfume, fragrance, essential oil or cosmeceutical agents and the like.

A media applicator includes an airbrush body couplable to a reservoir and defining a passage for conducting a gas, and a spray head couplable to the airbrush body. The spray head has a nozzle portion in fluid communication with a media tube extending into the reservoir, the nozzle portion defining a lumen in fluid communication with the passage when the spray head is coupled to the airbrush body. The nozzle portion further includes a discharge tube in fluid communication with the media tube, and situated such that gas flow from the passage through the lumen draws a media contained in the reservoir through the media tube into the discharge tube, and from the discharge tube into a flow of gas exiting the lumen of the nozzle portion. The spray head is detachable from the airbrush body to allow the nozzle portion to be carried away with the spray head.

A fluid dispersion assembly comprises a diffusion unit disposed in fluid communication with a fluid container, the assembly being powered by a compressed air source. The diffusion unit at least partially defines a diffusion chamber, and includes a diffusion assembly containing an atomizer assembly which, in combination with the diffusion chamber, generates a fluid dispersion from a mixture of compressed air and an operative fluid, for example, fragrant oils, essential oils, odor neutralizers, disinfectants such as triethylene glycol, air sanitizers, etc.

A device for discharging fluids includes a container, to be opened and closed, which forms an interior space of the device for accommodating a spray medium; a capsule connector means in order to establish a fluidic connection between an exchangeable capsule filled with gas and the device; a discharge opening through which the spray medium can be discharged from the device interior space upon actuating the device. A pressure regulator is provided in order to guarantee the discharge of the spray medium, for example, in the form of hot chocolate, at a uniform pressure.

A disposable gas diffusion device includes a gas supply device, which includes therein a gas inlet device, which includes a coupling section, and a compression element. The coupling section includes therein a gas conveyance hole. A container has an end connected to a diffuser that is provided with a gas entrance passage having an opposite end extending to a bottom of the diffuser. The bottom of the diffuser is provided with a liquid guiding device, which has an opposite end extending to a location adjacent to a bottom of the container. The diffuser has a top end in which an exit opening is formed. The gas supply device is operable to guide a pressurized gas into the container on induce a negative pressure zone inside the container in order to convey a liquid through the liquid guiding device to an atomization hole to be atomized and sprayed out.

A device for applying drywall texture material to a surface is provided. The device generally comprises a hollow tube for holding drywall joint compound, a spray nozzle with a removably attached air hose, a piston, and a ramrod. The device allows users to easily apply drywall joint compound to a surface to create various surface textures.

A particulate sprayer includes a gas reservoir to hold a gas, a liquid reservoir to hold a product, and a low pressure section including an exit opening connected to the liquid reservoir. The product includes a liquid and solid particles. The low pressure section transports gas released from the gas reservoir over the exit opening. The product is drawn, pushed, or drawn and pushed from the exit opening into the transported gas to create a spray of the product to be sprayed from the particulate sprayer.

Provided is a hypochlorous acid water spray device that utilizes ultrasonic spraying and inhibits decomposition of hypochlorous acid. The present invention relates to a hypochlorous acid water (7) spray device (100) including a storage unit (1) that stores hypochlorous acid water (7), an atomization mechanism (2) that atomizes the hypochlorous acid water (7) using ultrasonic vibration, and a guiding mechanism (3) that guides the hypochlorous acid water (7) to the atomization mechanism (2) by capillary action.
