The invention relates to an injection device (10) configured to atomize a liquid into droplets using a gas, comprising a hollow tubular body (12) of longitudinal direction (X). An internal wall (13) defines a first zone referred to as a contact zone (Z1) and a second zone (Z2). The body has: at least a first and a second inlet opening (14; 16) opening into the said first zone (Z1), so as to respectively inject a liquid and an atomizing gas, at least one outlet orifice (18) situated downstream of the first and second zones, for removing the atomized liquid from the body. The internal wall (13) of the body is provided, between the zones (Z1) (Z2), with at least one chicane (20.sub.i) configured so that, in each plane perpendicular to the longitudinal direction of the body containing the said chicane, this chicane extends over just part of the periphery of the internal wall (13).

In a cleaning nozzle unit including an inner liquid passage guiding a cleaning solution, an inner air passage feeding air to an outlet of the inner liquid passage, and an injection port that mixes the cleaning solution guided by the inner liquid passage and the air fed by the inner air passage and injects a mixture of the cleaning solution and the air to a surface of an object, a plurality of the injection ports are provided, are disposed at predetermined intervals and inject the mixtures in directions such that the mixtures hits each other in the surface at a substantially predetermined angle in a front view of the surface.

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.

During the rolling of a metallic flat rolling stock (1) in a roll stand (2), lubricating oil (5) is sprayed onto the rolling stock (1) and/or at least one roll (3,4) of the roll stand (2) by multiple spray nozzles (7) arranged beside one another. In each case, a mixing chamber (8) of a spray nozzle (7) is fed with a respective quantity of lubricating oil (5) via respective multiple oil inlet openings (9). The respective mixing chamber (8) is fed with compressed air (11) via respectively one air inlet opening (10). Compressed air (11) atomizes the lubricating oil (5) in the respective mixing chamber (8) to form an aerosol and, via respectively at least one nozzle outlet (12), is sprayed onto the rolling stock (1) and/or the at least one roll (3,4) of the roll stand (2).

The present disclosure provides an electrostatic nozzle and a controllable jet minimal quantity lubrication (MQL) grinding system. The electrostatic nozzle comprises a nozzle core; an upper nozzle body is connected above the nozzle core; a free space is formed between the upper nozzle body and the nozzle core for storing compressed air and reducing pressure; a lower nozzle body is connected below the nozzle core; a gas-liquid mixing chamber, an acceleration chamber and a nozzle outlet are sequentially arranged inside the nozzle core from top to bottom; and micro-bulges are uniformly distributed on an inner wall of the acceleration chamber.

The present application provides an atomization device and the atomization device. The atomization device (20) includes a nozzle body (201), the nozzle body (20) including a gas inlet channel (21), an atomization channel (22), and a liquid inlet channel (23). One end of the gas inlet channel (21) defines a gas inlet (211), and the other end of the gas inlet channel (21) defines a gas ejecting port (212) intercommunicating with the atomization channel (22). One end of the liquid inlet channel (23) defines a liquid inlet (231), and the other end of the liquid inlet channel (23) defines a liquid ejecting port (232) intercommunicating with the atomization channel (22). An inner diameter of the atomization channel (22) approaching the liquid ejecting port (232) is greater than an inner diameter of the gas ejecting port (212) to enable an intake gas flow from the gas inlet channel (21) to form a negative pressure region at such site and to facilitate mixing of the liquid and gas to form an aerosol. The atomization channel (22) defines an aerosol generating port (221) configured to eject the aerosol. The atomization nozzle and the atomization device provided by the present application can effectively improve the atomization efficiency, and solve the problem that the prior art split type atomization nozzle has excessive volume and inconsistent atomization efficiency.

A method of filling a hand held spray device is disclosed. The spray device includes a body having a reservoir. The method includes filling the reservoir with a first composition having a non-volatile silicone fluid, an antiperspirant active, an organoclay material, and at least one liquid activation enhancer having a Hansen Solubility Parameter for Hydrogen Bonding, .sub.h between about 2 and about 6 and a light transmittance value greater than 90%. The method further includes filling the reservoir with a liquid fragrance material after the reservoir is filled with the first composition to form an antiperspirant composition, attaching a valve to the body; and filling the reservoir with a propellant, wherein the hand held spray device has a propellant concentration after filling from about 30% to about 90% by weight of the total fill of materials within the reservoir and the non-volatile silicone fluid has a concentration from about 30% to about 70% by weight of the antiperspirant composition.
