A heatable ceiling boom for washing facilities, which is rotatably mounted on a bearing shaft that is fastened to the ceiling or to a wall of a wash box, and which is made up of one or more support arms via which the washing medium is supplied from the bearing shaft to high-pressure hoses leading to the operating means in the form of a washing brush and/or spray lance, for example, wherein the high-pressure hoses have an electrically heatable design, and at least one rotational power distributor is situated on the bearing shaft for supplying electrical energy from the stationary bearing shaft to the support arms rotatably mounted thereon, wherein the electrical heating takes place via a heating cable that is led inside the high-pressure hose with sealing.

The present invention relates generally to the field of pressure washer wands and a cleaning attachment that can be attached to any standard pressure washer wand. The attachment has a roller assembly with a bristled roller head. The head can be positioned in front of the spray tip of a wand such that water that exits the wand and causes the head to spin.

A dual purge ejector and a dual purge system using the same are provided. A first end of a main body is fully open and an ejecting end of a nozzle is located proximate to the opening hole. Therefore, even if the ejector is disconnected from an adapter, negative pressure is not formed in a main body, to prevent discharge of fuel evaporation gas into the atmosphere and a failure of the dual purge system may be reliably diagnosed.

Retaining bracket for a fluid spray delivery apparatus to ensure that an applicator rod remains properly attached to the apparatus and in fluid communication with the fluid even when subjected to a driving force. Also disclosed is a fluid application system or assembly, and a method of applying fluid using the same, the system or assembly including a source of fluid to be applied to a target object, a siphon gun assembly, an applicator rod, tubing for placing the applicator rod in fluid communication with the siphon gun assembly, and a retaining bracket that secures the tubing to the siphon gun assembly such that the tubing remains in place and does not disconnect from the siphon gun assembly when subjected to a driving force such as water under pressure.

Spray apparatus and uses thereof are described herein. A vacuum spray nozzle apparatus may include a first tube in fluid communication with a fluid source, a rotor coupled to the tube, a conduit in fluid communication with the passages of the first tube, and a second tube coupled to the conduit, the second tube being in fluid communication with a vacuum source. The rotor is in fluid communication with the pressurized fluid source. The conduit is substantially arched or angled such that an outlet of the conduit is offset a radial distance in a radial direction from the rotor axis, and when pressurized fluid is ejected from the outlet, during use, rotates the conduit. The vacuum spray nozzle apparatus is configured to remove components from a material through the second tube when a pressure of the system is reduced using the vacuum source.

Provided is a carwash machine. The carwash machine includes: a steam generator and a spray gun connected to the steam generator. The steam generator has a gas outlet used for discharging gas. The spray gun includes a spray gun outer shell and an operating handle. The operating handle is provided on the spray gun outer shell. The steam generator includes: a boiler body, the boiler body having a combustion chamber, and the combustion chamber being in communication with the gas outlet; an inner cover, the inner cover being sleeved on an outer side of the boiler body, and a gap between the inner cover and the boiler body forming a gas discharge channel used for connecting the combustion chamber and the gas outlet; and an outer cover, the outer cover being sleeved on an outer side of the inner cover. The spray gun also includes: a locking switch.

A self-contained washing device for vehicles and other uses that compactly combines the necessary washing components including a pressure pump, extension hose, pressure wand, soap holder and rechargeable battery into an integrated assembly that can be attached to a standard open topped bucket mounted to a rolling retaining platform enabling the user to wash a vehicle at a location that may be distant from a standard pressurized water supply.

A handpiece of a skin care device is disclosed. The handpiece includes a body part having an attaching and detaching hole provided on one side thereof, a solution introducing part linked with the attaching and detaching hole, an air discharging part, and a disposable tip module mounted onto the attaching and detaching hole of the body part. The tip module includes a cylinder body detachably mounted onto the attaching and detaching hole, and an inner cylinder configured to have a hollow inside and installed in the cylinder body. The hollow inside of the inner cylinder is linked with the solution introducing part and is configured as a solution injection flow channel in which a solution introduced from the solution introducing part flows when the tip module is mounted onto the attaching and detaching hole.

High pressure water jet gun comprising: a dispensing body (6); a gripping body (13) connected to the dispensing body (6); an actuation member (10) reversibly movable between an activation position, wherein it is active on a shutter member (9) in order to at least partly cause an open condition, and a rest position, corresponding to a closed configuration of the shutter member (9); a blocking means (15) reversibly movable between a safety configuration, in which it is active on the actuation member (10) to prevent a passage from the rest position to the activation position, and a working configuration, wherein it enables a reversible passage of the actuation member (10) between the rest position and the activation position. In particular, the blocking means (15) comprises a manual activation element (21) at least partially opposed to the gripping body (13) with respect to the dispensing body (6). The actuation member (10) and the activation element (21) are arranged on opposed portions of the dispensing body (6) so that a single hand of the user can act on the activation element (21) with the thumb and on the actuation member (10) with at least another finger of the same hand.
