Systems and methods for spraying a liquid treatment solution include a syringe attachment device and a handheld device. The syringe attachment device can be configured to secure a syringe containing the liquid treatment solution. The handheld device can have a movable slide configured to dispense the treatment solution from the syringe. The spray deposition system can include a cover' positioned to provide an impervious barrier between at least a portion of the syringe attachment device and the handheld device. The cover can be attached to the syringe attachment device prior to coupling the devices together. In an example, the cover can have a generally tubular shape with a closed end and an open end. The handheld device can be inserted into the cover and the cover can enclose the handheld device in the assembled position. In an example, the cover can be sterile and at least a portion of the syringe attachment device can be sterile.

An essential oil reflux-type atomizer comprising the following structures: chassis (10), housing (30), atomization chamber (310), gas pump (21), gas tube (22), gas nozzle (23), oil nozzle (24), filter atomization mechanism (40). The filter atomization mechanism (40) is installed in the housing (30) and has a plurality of filter housings (41). A lower end of each of the filter housings (40) has one or more through holes (411). When the gas nozzle (23) ejects an airflow, the airflow draws out the essential oil through the oil nozzle (24) to form a mixed airflow which passes through each of the filter housings (41) successively. Larger essential oil droplets in the airflow are filtered by each of the filter housings (41) to be recycled, while the atomized essential oil gas will pass through the through holes (411) of each of the filter housings to be dispensed. At the same time, the essential oil droplets in the through holes (411) are re-atomized by the airflow to improve the atomization performance. The atomization chamber (310) comprises a guide board guiding the airflow from the gas nozzle (23) upwards towards the filter atomization mechanism (40).

An essential oil reflux-type atomizer comprising the following structures: a chassis, housing, atomization chamber, gas pump, gas tube, gas nozzle, oil nozzle, and filter atomization mechanism. Oil and gas flow together at the gas and oil nozzles to disperse and atomize the oil in the gas flow. A heater is used to raise the temperature of the oil where it is atomized, either by heating the oil itself or by heating the gas flowing into the oil. Thus, the atomizer can have improved performance, especially with essential oils having high viscosity and molecular weight.

Systems and methods for spraying a liquid treatment solution can include a syringe attachment device and a handheld device, which are configured to be coupled together in an assembled position of the system. The syringe attachment device can be configured to secure a syringe containing the liquid treatment solution. In an example, the treatment solution can include autologous skin cells for treating a tissue wound. The handheld device can have a movable slide configured to dispense the treatment solution from the syringe. In an example, the spray deposition system can include a cover positioned to provide an impervious barrier between at least a portion of the syringe attachment device and the handheld device. The cover can be attached to the syringe attachment device prior to coupling the devices together. In an example, the cover can have a generally tubular shape with a closed end and an open end. The handheld device can be inserted into the cover and the cover can enclose the handheld device in the assembled position. In an example, the cover can be sterile and at least a portion of the syringe attachment device can be sterile. In an example, after delivery of the treatment solution, the syringe attachment device can be disposed of and the handheld device can be reused.

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 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. 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.
