The garden spray structure has a main body, a water guiding member and a spray head. The main body has a handle portion and a chamber portion which are connected with each other, the handle portion is configured for connecting with a water source and hand-held purpose, and water is fed to from the handle portion to the chamber portion while the handle portion is held. Furthermore, an engagement opening provided in front of the chamber portion is configured for engaging with the water guiding member, after a supply tube provided with the water guiding member is inserted the chamber portion. Also, the water guiding member is provided with a central shaft extending from the front opening, and the central shaft passes through the spray head and the central shaft is locked so that the spray head is mounted at the front of the water guiding member.

An applicator assembly for gel-based product and method of use that includes a housing enclosing a pump with a handle extending from the housing. The handle holds a flush mounted trigger assembly that operates the pump. Product is drawn from an external cartridge by vacuum. A movable plug maintains product structural integrity as product is withdrawn from the cartridge.

Improvements in an agricultural manual sprayer for preventing leakage of fluids such as insecticides, herbicides or fungicides that comprises tank with a large storage capacity into which a pressure vessel is installed. A manually activated pumping assembly is connected with the inferior section of the pressure vessel and also with the inferior section of the tank. The pumping assembly comprises a reciprocating piston pump for extracting the fluid from the storage tank and pressurizing it within the pressure vessel. The pressurized fluid is applied with a hose and a throttle valve attached to the pressure vessel. The assembly also comprises a double walled piston and barrier against leakage consisting of a ring with interior lips which seal it against the cylinder preventing the exit of fluid, forcing it to remain in the collection chamber until it is emptied with the downward movement of the piston, returning the liquid from the collection chamber to the storage tank through a return hose and internal ducts.

A powered spray system designed for home use comprises a chemical supply tank, a sprayer for applying a chemical in the chemical supply tank, and a coupling connecting a water source with the chemical supply tank and sprayer for mixing chemical contained in the chemical supply tank with a stream of water as the water is sprayed. The coupling comprises a first inlet configured to connect to a standard garden hose for connecting the coupling to the water source, an outlet configured to connect to a standard garden hose for connecting the coupling to the sprayer, and a second inlet configured to connect to the chemical supply tank.
