A hose end sprayer includes a concentrate tank and a sprayer head. The sprayer head has an inlet end, an outlet end and a flow tube, along with a suction tube and a valve. When the sprayer head is closed, neither the first nor the second flow orifice communicates with the flow opening and the concentrate opening is closed by the valve body. When the sprayer head is in wet mode, the vent opening communicates with the concentrate opening as concentrate is drawn into the flow tube. When the sprayer head is in dry mode, the concentrate orifice communicates with the concentrate opening to direct a portion of the fluid into the concentrate tank. A metering plate injects a selectively adjustable amount of concentrate into the fluid stream. The sprayer head may further include a concentrate basket to hold a dry product within the concentrate tank.

An undercarriage soapy foam dispenser having a handle adapted to receive pressurized water, a cleaning solution aspirator, a first supply line coupled to the cleaning solution aspirator, a second supply line disposed at a non-zero angle relative to the first supply line, a spray bar coupled to the second supply line, one or more nozzles coupled to the spray bar, and aerators respectively disposed between the nozzles and the second supply line.

A device for delivering an agent may comprise a chamber for receiving agent through an agent inlet; and a body received within the chamber. The body may be movable in first and second directions along a longitudinal axis of the chamber. In a first configuration of the body, an amount of the agent may flow into the chamber via the agent inlet. In a second configuration of the body, the agent is prevented from flowing into the chamber via the agent inlet. When the body is transitioned from the first configuration to the second configuration, the amount of the agent may be moved from a first position along the longitudinal axis of the chamber to a second position along the longitudinal axis of the chamber.

A shower head has upper and lower ends and a side wall in a frusto-conical configuration. An intermediate plate with a plurality of apertures is positioned between the upper and lower ends forming upper and lower chambers. A positioning ball has a lower portion within the upper chamber and an upper portion above the upper chamber. A hole is in the lower portion of the positioning ball. A cartridge supporting a quantity of therapeutic liquid is removably received in the lower chamber of the shower head. The therapeutic liquid is dispensed from the cartridge into a path of travel of shower water flowing through the shower head.

Proposed is a laser treatment device having a cooling system, the device including a laser module which irradiates a patient's skin with a laser, a sensing unit which detects a temperature of a surface of the patient's skin before, during, or after the skin is heated by the laser, a cooling module which includes an inlet which receives a refrigerant from a refrigerant storage unit, a nozzle which sprays the refrigerant on the skin, a conduit which connects the inlet with the nozzle, an flow rate control unit which controls a spray amount of the refrigerant by using a valve which is positioned on the conduit and connects or disconnects the inlet with or from the nozzle, and a refrigerant condition control unit which applies a thermal energy to the refrigerant by using a thermoelectric element located between the flow rate control unit and the nozzle.

A dispenser for mixing and dispensing a liquid chemical concentrate with a diluent from a container. The dispenser includes two slidable eductors one of which is also rotatable. Both a high and low flow rate can be obtained with simultaneous adjustment of concentration of the chemical concentrate. The dispenser has a high degree of accuracy of the amount of dilution of the chemical concentrate as well as positive positioning of the high and low flow rate.

A sprayer for mixed solution and water is revealed. The sprayer can be used for cleaning objects, spraying mixed solution for agricultural purposes, and so on. The mixed solution is formed by liquid mixed with water, while the liquid can be fertilizers, pesticides, detergents, and etc. The sprayer can selectively spray out the mixed solution or water only.

A shower head liquid agent dispenser includes a storage tank having a hollow interior space for storing a liquid agent, a first tubular member that is connected to the bottom end of the storage tank, a valve which can be manipulated between an on and off position, a second tubular member that is connected to a tee fitting which is selectively connected to a building's shower arm and a shower head assembly.

A soap dispenser showerhead for releasing soap directly into the shower stream for easier soap application includes a showerhead comprising a handle portion and a head portion. A water flow channel extends through a bottom side of the handle portion up through the head portion to be released through a plurality of flow apertures. A valve is coupled within the water flow channel and has a valve control extending through the handle portion. A soap dispenser is selectively engageable within a cavity of the handle portion of the showerhead adjacent the valve. The soap dispenser has a storage compartment configured to store liquid soap and a nozzle in fluid communication with the storage compartment and the valve. The valve control regulates the flow of liquid soap into the water flow channel.

The present invention provides a multi-mode high-pressure foam lance, which includes a foam-making component and a spray-mode component, wherein the foam-making component and the spray-mode component are connected through a sheath, the sheath is internally provided with an air mixing connecting tube, the spray-mode component includes a foam-making eccentric disc and a nozzle-mode rotary disc, an axis of the foam-making eccentric disc and an axis of the nozzle-mode rotary disc are fixedly connected through a positioning screw, a positioning pin is arranged between the foam-making eccentric disc and the nozzle-mode rotary disc, a spray hole of the foam-making eccentric disc is corresponding to a nozzle of the nozzle-mode rotary disc, and metallic foaming cotton is arranged between the foam-making eccentric disc and the air mixing connecting tube. The present invention has the advantages of reasonable structure design and multi-spray modes optimally matched with the foam-making component and convenient to switch, which greatly enriches the spray forms on the premise of optimizing a foam-making effect, and meets the requirements of user groups with different heights on covering and spraying foams on surfaces of various objects.
