A hand-held integral airbrush includes a shell provided with a grab handle, wherein an upper accommodating cavity and a lower accommodating cavity are formed in the shell, an airbrush assembly is arranged in the upper accommodating cavity of the shell, and an air pump assembly is arranged in the lower accommodating cavity of the shell and is used for pumping compressed air into the airbrush assembly. The hand-held integral airbrush further includes a switch part, as well as an operating button which includes a first control part and a second control part. According to the hand-held integral airbrush, an air pump and an airbrush are integrated in the ergonomically designed grab handle, and the air pump and the airbrush are controlled by the trigger-type operating button to operate, so that the hand-held integral airbrush is more convenient to hold and operate.

A spray tip includes a cylindrical body having a through hole oriented along a fluid flow axis, and a spray outlet piece and upstream chamber piece located in the through hole. The spray outlet piece includes an outlet aperture configured to atomize a spray fluid. The upstream chamber piece includes an internal aperture wall with an upstream surface and a downstream surface, and an aperture through the wall. The aperture includes an inlet orifice and an outlet orifice. The spray tip further includes a turbulation chamber defined by the spray outlet piece and the upstream chamber piece.

A holding device is used to maintaining a push button of a spray container to be pressed to release contents without continuous press by an operator. The holding device for a spray container comprises a supporting part which is placed around the push button, an adjusting part having a pillar-shaped portion standing on the supporting part and a diving board-shaped portion connected to the pillar-shaped portion and extending over a top of the push button, on a top of the diving board-shaped portion having a recess; and an auxiliary part being pillar-shaped and standing on the supporting part, having a protrusion toward the adjusting part to be engaged with the recess.

A shower column assembly includes a shower column, and first and second shower column mounts. A showerhead is fluidically connected at a first end of the shower column, and a hand shower is fluidically connected to the shower column via a hose connection at a second end of the shower column opposite the first end. A diverter is positioned within the shower column at the supply location, and a flow selection valve is positioned offset from the diverter along a fluid path defined, at least in part, by the shower column.

A water discharging device includes a body including a first water channel connected to a water supply source, and a second water channel connected to the first water channel and to an external entity; and an opening and closing portion including a first opening and closing member opening and closing a first opening and closing hole formed in the first water channel, and a second opening and closing member opening and closing a second opening and closing hole formed in the second water channel. The first opening and closing member moves along the first water channel to open and close the first opening and closing hole as the second opening and closing member moves in the second water channel to open and close the second opening and closing hole.

A spray tip includes a cylindrical body having a through hole oriented along a fluid flow axis, and a spray outlet piece and upstream chamber piece located in the through hole. The spray outlet piece includes an outlet aperture configured to atomize a spray fluid. The upstream chamber piece includes an internal aperture wall with an upstream surface and a downstream surface, and an aperture through the wall. The aperture includes an inlet orifice and an outlet orifice. The spray tip further includes a turbulation chamber defined by the spray outlet piece and the upstream chamber piece.

The invention solves the problem of protecting air-craft components during finishing. Such components are large and require masking films of vast dimensions which are difficult to handle and position rapidly. The invention relates to films packaged to facilitate transport, and to a method of positioning the packaged films on the corresponding components. The longitudinal and/or transverse portions of the films are packaged by means of at least one operation chosen from among: accordion folding, telescopic folding, gate folding, roll folding, winding around a mandrel, and winding on itself. The packaged films can have positioning markers on at least one surface and/or tear lines suitable for detaching the portions of film to be separated. The invention also concerns a kit comprising a film and a guide element for guiding the positioning of the film on the component.

A spray wand for use with a chemical or chemical formulation in solid form. The wand hose end has a wand hose end valve for control of water flow from a hose. A refill cartridge having a swirl chamber may be attached to the hollow tube. The refill cartridge has at least one nub, indent and/or external channel or groove on its external surface.

Disclosed is a holder device with waterway switching function. Water flows out of the first outlet waterway when the handle matter is pulled out of the socket, after the handle matter is inserted to the socket, water can flow out of the first outlet waterway, the second outlet waterway or the two outlet waterways by the second switch mechanism, the automatic switch and the practical need are elegantly combined, the present invention has compact structure and occupies small space.

A switchable shower head includes a waterway device providing at least two water flow outlet functions; and a waterway switching device including a water diversion plate rotatable to switch between outlet functions; a fixing seat disposed above the water diversion plate; a ratchet wheel coaxially connected to and synchronously rotatable with the water diversion plate via the fixing seat and including a ratchet; a transmission element that abuts against the ratchet to cause the ratchet wheel to rotate; a transmission rack that has the transmission element slidably assembled thereto to slide in a sliding direction, that is movable with respect to the ratchet wheel in a moving direction, and that is resettable by two or more elastic elements; and a driving device that comprises a press button in communication with the fixing seat and a driver mechanism provided between the press button and the transmission rack.
