A pressure assisted washer or pressure washer with hose reel and motor pump assembly. The hose reel defines a bore in which a motor pump assembly is disposed. The hose reel comprises a cylinder having an aperture through which pressurized fluid can be accessed through a coupling in fluid communication with a pump. The pump has a rotating collar.

A foam generating device for a high-pressure water gun has a supporting body defining part of a conduit, which extends along an axis and has a mixing chamber communicating with a lower inlet, and subject, in use, to a vacuum to aspirate a liquid from said lower inlet; the device has a first sleeve which is fitted around one end of the supporting body, is axially fixed, is rotatable and is provided with an end portion carrying a nozzle; such a nozzle defines the outlet of the conduit and is adjustable so as to vary the outgoing flow type between a fan-like jet and a solid stream jet; the device has, in addition, a second sleeve which is coupled to the first sleeve in a fixed axial position and in a rotatable manner and is provided with cams to adjust the nozzle in response to a rotation of the second sleeve with respect to the first sleeve.

While the described wand can include any suitable component, in some cases, it includes a wand head having a vacuum port with a front face and a back face, a jet port that is coupled at the back face of the vacuum port, and a jet that is coupled to the jet port, the jet being configured to spray effluent through the vacuum port to a surface to be cleaned. In some cases, the front face includes a first jog that extends from a front side of the front face and across a width of the front face. In some cases, the second face includes a second jog that extends across a width of the back face of the vacuum port such that the second jog extends into the vacuum port and defines a second recess at a back side of the back face. Additional implementations are also described herein.

An apparatus that can be connected to a conventional sprayer bottle that permits the sprayer bottle to generate ozonated and ionized water to be used as a cleaning fluid. The apparatus includes an ozonator element submerged in the bottle water via a first electrical conductor and an ionizer lead submerged in the water via a second electrical conductor which is connected to an ionizer that is not submerged. Respective apertures are formed in the sidewall of the bottle, each having respective electrical connectors to permit the respective electrical connections to different power sources. The dip tube of the spray head is then passed through the top opening and into the water in the bottle and the spray head is secured onto the bottle. Electrical energy is provided through the respective conductors to ozonate and ionize the water in the bottle for use a cleaning agent. Humidifier or vaporizer versions of this invention provide an ozonated and ionized water mist or vapor.

A system to process a waste food includes a housing; at least one drum enclosed in the housing where the waste food is mixed up and digested by microorganisms or dehydrated; and at least one cleaner incorporated in or on the machine to permit a jet of water to be turned on and off to clean the drum.

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.

A hand-held personal hygiene device includes a main body having an upper end, a lower end, and a pump therein. The pump is configured to pump water or another fluid from an inlet port at the upper end to an outlet port at the lower end. A reservoir has a lower base configured to removably seat in the upper end of the main body to engage and open a self-closing valve with the inlet port of the main body. A tubular nozzle member has a lower end comprising one or more nozzle outlets and an upper end configured to be removably secured to the outlet port of the main body causing liquid pumped by the pump to flow through the tubular nozzle member to the one or more nozzle outlets. The reservoir and the main body may be aligned to form a liquid flow path that may be held vertically to allow gravity flow from the reservoir to the pump.

An electric starting system for an internal combustion engine is provided. The starting system includes a battery, a starter motor, and a blower housing. The starter motor is configured to start the internal combustion engine. The battery is integrated with the blower housing.

A washing system that includes a vessel for storing a cleaning solution, an inlet connection point for pressurizing the vessel, and an outlet connection point for dispensing the cleaning solution. In one embodiment, the washing system includes a regulator valve configured to remain open and allow the inside of the vessel to be filled with pressurized gas via the inlet connection point when pressure inside the vessel is below a predetermined value and automatically close when pressure inside the vessel exceeds the predetermined value. In another embodiment, the washing system includes a relief valve (e.g., at the top of the vessel) that is configured to remain closed when pressure inside the vessel is below a predetermined value and automatically open when pressure inside the vessel exceeds the predetermined value.

The present disclosure relates generally to protective devices and cover members. In some embodiments, cover members are provided that are operable to protect covered components and to allow heat dissipation from the components. Cover members of the present disclosure are suitable for use with heat exchangers including, for example, those provided with hot water pressure washers.
