The present invention relates to a device for cleaning and/or disinfecting surfaces, particularly for cleaning inner surfaces of the toilet bowl. The device comprises an elongated housing connected to a bottle with the cleaning and/or a disinfecting liquid, and a pumping mechanism for pressurizing said liquid composition, and at least one nozzle for the output of said liquid composition, wherein the nozzle is in fluid communication through a conduit of the device with said pumping mechanism. The pumping mechanism is provided at one side of said housing and said at least one nozzle is provided at the opposite side of the housing.

A liquid sprayer apparatus includes a multi-chamber spray mechanism, with at least one chamber being adapted to accumulate pressurized fluid for dispensation over an extended time period. The liquid sprayer apparatus is capable of emitting a liquid spray over a period of time that is substantially greater than a manual pump action applied to the trigger.

A trigger sprayer for connection to a container or liquid product which is to be dispensed is disclosed. The trigger sprayer includes a trigger body with a first engagement member and a nozzle with a second engagement member. The first engagement member is constructed and arranged to receive the second engagement member. The second engagement member is moveable relative to the first engagement member between a first position and a second position. Movement of the second engagement member relative to the first engagement member between the first and second positions encounters a region of increased resistance.

A connection system between a head and a bottle of a trigger dispensing device includes a main skirt having a first flexible tab and a neck (2b) having a first sloping plane and a first pocket. The first flexible tab extends circumferentially from a first end to a second end, and the first end is joined to an annular wall by a closing wall. The system also provides for an auxiliary window obtained through the annular wall of the main skirt, and a rigid auxiliary tooth of the neck, suitable to snap into the auxiliary window.

A spray nozzle for dispensing cleaning solution including embedded, battery-powered ultraviolet lights is disclosed. This invention improves the detection of contaminants that need to be removed or cleaned and obviates the need to locate a separate UV light in flashlight form. In addition, this invention maintains the traditional shape of a spray bottle and nozzle without adding any cumbersome elements that would make cleaning difficult.

A trigger type sprayer capable of easily performing air vent in a space between a second valve and a first valve, and preventing leakage of liquid in use is provided. The present invention includes a body 11 having a first flow channel 11a through which liquid can flow, a second flow channel 11d communicating with the first flow channel 11a, and a cylindrical cylinder chamber 11b communicating with the second flow channel 11d; a hollow piston 13 slidably incorporated into the cylinder chamber 11b, having a valve seat 13b and a hollow portion 13d of a second valve 14, and sliding back and forth according to operation of a trigger 12; the second valve 14 incorporated into the hollow portion 13d of the hollow piston 13 and positioned at a downstream side; and a first valve 15 incorporated into the cylinder chamber 11b and positioned at an upstream side, wherein the first valve 15 is pressed by the second valve 14 so that the first valve 15 is opened.

The bottle and spray assembly is a device that is designed pump liquids through a nozzle. The pump of the bottle and spray assembly is manually operated. The bottle and spray assembly is designed to rest on the arm of the user while the user holds a handle. The placement of bottle and spray assembly is in such a manner that the arm holds the bottle and spray assembly in place while the user pulls on the handle. The motion of pulling the handle operates the pump action within the spray assembly, which pumps the liquid through a nozzle. The bottle and spray assembly comprises a bottle and a spray assembly.

The invention relates to a pump comprising a piston (1) which slides in a body (3) having a chamber (5) defined between an inlet valve (11) and an outlet valve (12), comprising an outlet valve element sliding during actuation in a sealed manner in the chamber (5), which comprises passage means (40) such that, at the end of the actuation, said outlet valve element (39) cooperates in a non-sealing manner with said passage means (40) in order to open said outlet valve (12), said inlet valve (11) comprising an inlet valve element (10) which slides after closure of the inlet valve (11) in a sleeve (9) of the body (3) having a reduced diameter and containing a spring (20) bearing on said inlet valve element (10) and on a bottom of said sleeve (9), said spring (20) returning the piston (1) into its rest position, said sleeve (9) having an inner diameter of less than 4.2 mm, said spring (20) having a force of at least 20 N, so that said pump delivers said fluid product at a pressure (P) of at least 15 bars.

A pre-push miniaturized atomizing device has blank cap fixed to the outer diameter of pump nozzle underneath L-shaped water inlet of body. The blank cap and elastic body are fastened to the hole on the side of a large ring of body, the elastic body water outlet hole has a fastened and fixed valve needle, the thru-hole is connected to piston cavity in body, the outer diameter of the elastic body water outlet hole is set against the inner wall underneath the piston cavity at the L-shaped water inlet hole of the body to form a spray hole clearance. As the valve needle floats up and down in the water outlet hole, the clearance passage between the valve needle and elastic body opens or closes, while the spray hole clearance between the elastic body and the piston cavity closes or opens as corresponding to the deformation of the elastic body.
