The present disclosure has the following advantageous effects: by mounting a metal tube in the spray head, the metal tube can reduce the outward expansion pressure of high-pressure water flow, thus enhancing the pressure resistance of the metal tube, the metal tube is not easily damaged, and the spraying can can be connected to a higher-pressure water gun, the pressure resistance is excellent, and the service life of spraying can is increased, thus improving the use experience of the user.

A countertop foam dispenser has a spout made of a spout extension front housing and a spout extension rear housing. The spout includes a spout nozzle with a spout opening. A spout mounting shaft is mounted to the spout at a mounting shaft bracket. A mixer pump housing has a spout retainer latch. The mixer pump housing houses a mixer pump. The mixer pump includes a motor. A retainer notch is formed on the lower portion of the spout. The retainer notch is configured to engage the spout retainer latch. A bottle contains liquid soap. The bottle has a connection to the mixer pump housing.

A fluid pump includes a press head portion, first and second unidirectional-valves, and extensible sleeve-pipe. Disposed in the press head portion, the first unidirectional-valve allows fluid to flow from its second end to its first end. The extensible sleeve-pipe includes a rebound element and outer and inner pipes which form a capacity-variable storage chamber. The inner pipe has a first end communicating with the first unidirectional-valve and a second end fitted to a first end of the outer pipe. The second unidirectional-valve allows the fluid to flow from its second end to its first end. The first end of the second unidirectional-valve communicates with the second end of the outer pipe. Upon contraction displacement of the inner pipe, the fluid flows from the storage chamber into the discharge passage via first unidirectional-valve. Upon expansion displacement of the inner pipe, the fluid flows into the storage chamber via second unidirectional-valve.

The invention relates to a wiper blade (10) to clean a vehicle window (1), with a wiper blade body (18), with the wiper blade adapter (14) to fasten the wiper blade (10) to a wiper arm (12), with at least one spray opening (20) arranged on the longitudinal side of the wiper blade body (18) for spraying a cleaning medium on the vehicle window (1), wherein the at least one spray opening (20) is hydraulically connected to a supply element (30) arranged in the area of the wiper blade adapter (14), and wherein the supply element (30) has at least one connection element (31, 32) to supply at least one cleaning liquid (2) to the supply element (30). It is provided according to the invention that the supply element (30) has a device (40) to supply air and a mixing device (35) to generate a cleaning foam as a cleaning medium, the cleaning medium being composed of the cleaning liquid (2) and the air.

A soap dispenser including a rigid cartridge, an inverted dispensing pump, a collar carrying a lever for actuating the pump, and a venting system for equalizing air pressure in the rigid cartridge. The rigid cartridge and collar cooperate to removably attach the soap dispenser to a wall-mounted bracket, in which at least the rigid cartridge is disposable being made of recyclable and/or biodegradable material.

A countertop foam dispenser has a spout made of a spout extension front housing and a spout extension rear housing. The spout includes a spout nozzle with a spout opening. A spout mounting shaft is mounted to the spout at a mounting shaft bracket. A mixer pump housing has a spout retainer latch. The mixer pump housing houses a mixer pump. The mixer pump includes a motor. A retainer notch is formed on the lower portion of the spout. The retainer notch is configured to engage the spout retainer latch. A bottle contains liquid soap. The bottle has a connection to the mixer pump housing.

The present disclosure relates to a foam machine. Liquid for generating foams is conveyed onto a laminating member through a liquid pump. The laminating member further conveys the liquid onto a foam forming device. On the foam forming device, a rotating ring is provided with a plurality of forming rings and a plurality of forming ribs, so that a plurality of foam film forming holes are formed in the rotating ring; afterwards, as the rotating ring rotates, the laminating member can form foam films on the respective foam film forming holes, and continuous foams are formed after an air flow is blown through; the foams are pushed by the air flow to be continuously sprayed out; and new foam films are continuously formed on the respective foam film forming holes.
