Abstract: A garden sprayer includes: comprises a main body, a spray head, a control valve set, a pressing handle and a fastening device. The fastening device is pivoted on the main body adjacent to the pressing handle. The fastening device has at least two brackets and a pressing rod connecting the two brackets. The pressing rod of the fastening device pushes against the third locking edge of the pressing handle to hold down the pressing handle for a constant water flow without the pressing handle needing to be pressed by the user. When the pressing handle is held down, the cover of the spray head can be rotated to adjust a gap between the spraying aperture of the cover and the head portion to adjust the water flow rate.

Abstract: A sprayer for a hose includes: a handle portion, a tube portion and a water control valve set. The handle portion and the tube portion are two individual metallic members. The handle portion and the tube portion are assembled together, and the water control valve set is disposed in the handle portion. Moreover, the handle portion is placed into a mold to form a grip cover around the handle portion covering the connecting tube and the connecting member to combine together the handle portion and the tube portion.

Abstract: A garden hose sprayer has a main body, an adjusting member, a flow control shaft, a spray head, a pressing handle, the two stopping knobs and an axial rod. The pressing handle is capable of staying in a fixed compressed status, and the adjusting member can drive the flow control shaft to rotate to provide adjustable flow after the pressing handle is fixed.

Abstract: An easy-clean spray head for a garden hose comprises a spray member, an adjustment device and a spray head. The spray member has a hollow body having a water intake channel, a water outlet channel, a pivot portion protruding from a surface of the spray member and attached to a handle, a valve seat disposed in the hollow body having two connecting openings respectively disposed on two sides to respectively fluidly connected to the water intake channel and the water outlet channel, and an outlet head attached onto a front end of the spray member. The adjustment device comprises a knob valve capable of receiving a securing member, a valve cap, a rotatable valve, an elastic member and a valve stem. The spray head comprises a spray member and a cover. The spray member is a flexible material and having a plurality of spray nozzles individually providing a fluidic path.

Abstract: The present invention relates to an acrylated semi-crystalline hyperbranched polyurethane oligomer and a preparation method thereof, which is characterized in that on the basis of the synthesis of hyperbranched polyurethane oligomer, it adopts a two-step process to make modifications to form a methacrylic and/or acrylic double bond and a long carbon chain with a carbon atom number higher than 10 or a benzene ring or a naphthalene ring at the terminals. The obtained oligomer has a lower melting point and a higher glass transition temperature and can be cured by means of radiation, and the curing rate is high enough to effectively improve production efficiency and save energy to form a cured film having a higher hardness and excellent thermal stability. The raw materials used in the method of the invention are easily obtained, and the method is suitable for large-scale production in industry.

Abstract: A holder for displaying a garden hose includes a base, a holding board, and a plurality of supporting rods disposed between the base and the holding board. The base has positioning holes at four corners and a center of the base, and a plurality of protrusions disposed in a predetermined arrangement on an upper surface of the base. Two long side edges of the base have an inclined or beveled surface, and the holding board has a plurality of fastening slots with different depths on both of two opposing sides. The fastening slot has a V-shaped opening with a narrowing end and a curved surface at the end. The curved surface has three evenly placed flanges, and each flange narrows or tapers from an upper side to a lower side of the holding board. A lower end of two lateral sides of the curved surface has a stopping edge. The narrowing opening of the fastening slot assists a positioning movement, and the arrangement of the three flanges and two stopping edges stabilizes the positioning of the garden hose.

Abstract: A gardening sprinkler includes a water inlet member having a water inlet channel, a water outlet member pivotally mounted on the water inlet member and having a water outlet channel connected to the water inlet channel of the water inlet member and a spraying head pivotally mounted on the water outlet member and having a plurality of spraying holes each connected to the water outlet channel of the water outlet member. Thus, the water outlet member is rotated relative to the water inlet member, and the spraying head is swiveled relative to the water outlet member so that the spraying head is pivoted relative to the water inlet member in a two-dimensional manner.

Abstract: A spraying gun includes a handle having a mounting portion which has a receiving hole, a shank connected with the handle and having an end provided with a plug inserted into the receiving hole, a locking cap mounted on the shank and locked onto the mounting portion, an extension secured on the locking cap, and a resilient grip mounted on the shank and locked onto the extension. The extension has an outer wall provided with a plurality of positioning bosses engaging the grip. The grip has an end portion surrounding the extension and engaging the positioning bosses. Thus, the end portion of the grip engages the positioning bosses so that the grip is locked onto the extension closely and tightly to prevent the grip from being detached from the extension during a long-term utilization.
