Aerosol actuator for an aerosol device

Aerosol spray devices () may include one or more actuators () located on the sides or on the rear of the device wherein actuation of the one or more actuators disperses product from a container in communication with the spray device. A selector mechanism () may be used to toggle between an 'on' and an 'off' position for the one or more actuators.

Spray devices and methods for using the same

A cartridge for a handheld electrohydrodynamic (EHD) spraying device and a spraying device incorporating the cartridge. The cartridge is disposable, and can contain therapeutic products. The device includes a wetted lead screw with a compliant seal, where the placement of the seal relative to the screw inhibits leakage during both cartridge use and storage. A frame disposed within the cartridge acts as a load-transferring mechanism for the weight of the cartridge to a handle of the spraying device.

Handheld sprayer with removable cartridge and method of using same

A cartridge for an electrohydrodynamic spraying device and a spraying device incorporating the cartridge, where the cartridge includes a locking mechanism. The cartridge is disposable, and can contain therapeutic or other fluid products. The fluid is delivered from the cartridge by a shaft-mounted piston, while the locking mechanism can be selectively engaged with the shaft such that in the engaged position, the locking mechanism prevents the piston from advancing by inhibiting movement of the shaft. When the locking mechanism is disengaged from the shaft, the shaft and piston are free to move, such as in response to a power source in the spraying device. The selective engagement between the locking mechanism and the shaft during periods of inoperability of the spray device prevents the buildup of fluid pressure in the cartridge that otherwise could blurt out upon subsequent operation.

Lead screw locking device

A method for delivering an aerosol, especially an aromatic aerosol, comprising the steps of contacting a capillary wick, comprising an EHD comminution site, with a liquid source, whereby at least a portion of the liquid transports to the EHD comminution site; applying a voltage to the liquid within the capillary wick at a location spaced apart from the liquid source and proximate the EHD comminution site; and applying a ground reference at a location external to the EHD comminution site, wherein at least a portion of the liquid EHD comminutes to form a spray having a generally-consistent flowrate and a device therefor.
