A disinfecting device is easy to use and can be easily mounted or removably connected in a dental operatory or other similar environment. The device can include a removable solution chamber attached to a base unit. The solution chamber can be a refillable chamber or a disposable chamber. The base unit can receive pressurized air, typically from a standard connection present in the dental operatory, or a dental chair, or the like. The pressurized air can be used to deliver a mist or an electrostatic fog of the solution in the solution chamber out of a nozzle. The solution bottle can be directly attached to the nozzle/sprayer device, with an air hose extending therefrom. In use, the user can turn on the system and use an activation/deactivation mechanism to deliver the atomized mist or fog to all surfaces in the room.

According to one embodiment of the invention, a coating apparatus includes a first pipe, a first pump, a first nozzle, a second nozzle, and a holder. The first pipe includes a first inflow port, a first outflow port, and a second outflow port. The first pump is configured to supply liquid toward the first inflow port. The first nozzle includes a first nozzle inflow port and a first nozzle discharge port. The first nozzle inflow port is connected to the first outflow port. The first nozzle discharge port is configured to discharge the liquid passing through the first pipe. The second nozzle includes a second nozzle inflow port and a second discharge port. The second nozzle inflow port is connected to the second outflow port. The second nozzle discharge port is configured to discharge the liquid passing through the first pipe. The holder holds the first nozzle and the second nozzle. The holder is configured to form a first state and a second state. In the first state, a height of the first nozzle discharge port and a height of the second nozzle discharge port are not less than a height of the first pipe. In the second state, the height of the first nozzle discharge port and the height of the second nozzle discharge port are lower than the height of the first pipe.

Delivering a payload across a plasma membrane of a cell includes providing a population of cells and contacting the population of cells with a volume of an aqueous solution. The aqueous solution includes the payload and alcohol content greater than 5 percent concentration. The volume of the aqueous solution may be a function of exposed surface area of the population of cells, or may be a function of a number of cells in the population of cells. Related compositions, apparatus, systems, techniques, and articles are also described.

An atomizing disc, an atomizing device with the atomizing disc, and an unmanned aerial vehicle are provided. The atomizing disc includes: a bottom disc, an upper surface of the bottom disc being provided with a liquid inlet space; and a plurality of ribs, the plurality of ribs being disposed on the upper surface of the bottom disc and being spaced apart in a circumferential direction of the bottom disc. A centrifugal flow passage in communication with the liquid inlet space is defined between two adjacent ribs and the bottom disc. An end of a rib close to an edge of the bottom disc is provided with a first groove penetrating a side portion of the rib so as to cut fluid flowing through the centrifugal flow passage.

A spray apparatus having built-in air regulation and a swivel connection to an air supply and uses thereof are described herein.

A fluid delivery system includes a smart hose. The smart hose includes a fluid conduit configured to deliver a fluid. The smart hose further includes a first electrically conductive element configured to deliver electricity through a length of the smart hose. The fluid delivery system further includes master hub disposed on a fluid delivery device. The fluid delivery system also includes at least one slave hub disposed on the smart hose and communicatively coupled to the master hub.

In a cleaning method for removing adhesive residues from surfaces, in particular after separating an adhesive connection between adhesively joined partners, liquid carbon dioxide from a reservoir enters a jet, apparatus and is guided there through a first dosing unit into an expansion chamber wherein a cold-resistant liquid is then supplied to a mixture created in the expansion chamber from gaseous carbon dioxide and carbon dioxide particles and wherein the mixture, to which the cold-resistant liquid has been added, exits the jet apparatus via an outlet opening thereof. Furthermore, a jet apparatus removes adhesive residues from surfaces.

A powered disinfectant dispensing device for providing disinfectants is presented. The powered disinfectant dispensing device allows for an easy distribution of disinfectant to a person. The device is both light weight and efficient while providing a small footprint for storage. The device automatically dispenses liquid disinfectant in an airborne manner. The device has a fan that is utilized to provide wind behind a disinfectant to cause the disinfectant to become airborne and evenly distribute the disinfectant.

A wobble plate for a sequentially activated multi-diaphragm foam pump includes three or more wings, a wobble plate shaft, and an aperture located in each of the three or more wings. A first wing is configured to have a first distance from first contact surface of a first pump diaphragm. A second wing is configured to have a second distance from a first contact surface on a second pump diaphragm, and a third wing is configured to have substantially the second distance from a first contact surface on a third pump diaphragm.

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.
