The invention relates to an electronic smoking device (100) with an atomizer/liquid reservoir portion (114) and to an atomizer/liquid reservoir portion (114). In order to facilitate refilling a liquid reservoir (134) of the atomizer/liquid reservoir portion (114), the atomizer/liquid reservoir portion (114) comprises a docking valve (146) for docking a source of liquid (148) to be stored in the liquid reservoir (134), and a liquid duct (156) that is adapted to receive liquid (172) from the docking valve (146) and that opens into the refillable liquid reservoir (134) at a predetermined distance (A) to the docking valve (146).

Disclosed is a liquid dispenser, including a pumping structure and a pressure-accumulation ejecting structure which cooperate for use, wherein the pumping structure includes a main frame, a liquid storage cavity and a piston rod, the liquid storage cavity is built into the main frame, and the lower end of the liquid storage cavity is provided with a liquid inlet and a liquid outlet which can be opened and closed; the piston rod can move upward and downward along the liquid storage cavity under the action of a driving member, when the piston rod moves downward, only the liquid outlet is in an open state, and when the piston rod moves upward, only the liquid inlet is in an open state. The liquid dispenser of the present disclosure is simple to assemble, and the service life of the liquid dispenser is prolonged while improving the stability of assembly of parts.

A handheld misting device, having a fluid tank that can be pressurized to force the contained fluid under pressure through a fluid delivery system, includes a hand-operated pump for injecting air into the fluid tank to pressurize the fluid tank. The pump includes a pump handle located at the bottom of the tank at one end of a rod, and a piston at the other end of the rod. The pump handle rotates in order to lock, in a retracted position, against the tank; the form factor of the handle conforms to that of the tank, to define an unbroken outer surface of the device when the handle is locked in the retracted position. A pressure-relieving air channel extends through the piston, the rod, and the pump handle to emit air out of the pump and into the environment when the fluid tank is at a maximum pressure.

The present invention relates to a portable hydrogen water mist sprayer comprising a water container which has an open-top coupling part protruding from the top center, a central case, the bottom of which becomes coupled to the top of the water container, and a top cap that becomes coupled to the top of the central case, and wherein an enclosed installation frame placed in the bottom of the central case and the bottom of the central case, which becomes coupled and fixed to the bottom of the central case, are coupled to the open-top coupling part of the water container for airtightness, and an airtightness frame that has a discharge guide groove and a discharge guide hole to selectively release the gas from hydrogen water production inside the water container is applied so that, in case the internal pressure of the water container exceeds a certain level, the gas from inside the water container can flow through the enclosed installation frame and airtightness frame and be discharged outside via the discharge guide groove and discharge guide hole. Accordingly, in case the internal pressure of the water container exceeds a certain level, infiltration of gas containing hydrogen components and/or water molecules into the electrical components involved in hydrogen production, such as the control unit, can be prevented, and the gas is discharged outside so as to substantially improve the safety and durability of the mist spraying device.

A reusable dispensing container assembly, having a canister having a first end and a second end, the canister having an upper chamber to hold dispensable substance, an actuator arranged proximate the first end of the canister, in communication with the chamber, the actuator having a nozzle arranged to eject the dispensable substance, and, a deformable piston arranged within the canister below the upper chamber, the piston further arranged to sealingly engage an inner surface of the canister, the piston arranged for upward movement within the canister when the actuator is actuated, the deformable piston forming a lower chamber arranged to hold pressurized gas, the deformable piston comprising at least one integral external O-ring about its circumference arranged to sealingly engage the inner surface of the canister and maintain separation of the dispensable substance and the pressurized gas.

A dispenser for applying liquid, having a housing with an applicator opening and a liquid reservoir. The dispenser has a ventilation duct by which an ambient atmosphere is connected to the liquid reservoir so that, after the application of liquid, an inflow of air from the atmosphere is permitted into the liquid reservoir. The dispenser is provided with a detection installation which for detecting an application procedure detects air flowing in through the ventilation duct. The dispenser has a protective cap covering the applicator opening on the housing. The dispenser in the ventilation duct has a switch valve operable by activating a push-button on the external side of the housing. The protective cap acts on the push-button when placed on the housing or when the protective cap is being placed thereon to open the switch valve.

A misting device has a form factor that allows the device to be handheld. The device includes a fluid tank that can be pressurized to force the contained fluid under pressure through a fluid delivery system. A hand-operated pump injects air into the fluid tank to pressurize the fluid tank. The pump includes a pump handle located at the bottom of the tank at one end of a rod, and a piston at the other end of the rod. A pressure-relieving air channel extends through the piston, the rod, and the pump handle to emit air out of the pump and into the environment when the fluid tank is at a maximum pressure.

A two-component piston for a cartridge includes a piston cover as the first component and a piston body as the second component. The piston has a first side and a second side, and a rear side of the piston cover arranged adjacent to at least a part of the piston body. A front side of the piston cover is arranged at the first side, and the rear side of the piston cover includes a valve member. The valve member is to be received within the piston body and to extend into the piston body towards the second side. The piston cover is configured to be moved relative to the piston body on actuation of the valve member and the piston cover is non-releasably connected to the piston body.
