Abstract: A fire apparatus includes a housing, a water tank mounted in the housing, a support unit mounted on the housing, a spray gun mounted on and supported by the support unit, a hose having a first end connected with the water tank and a second end connected with the spray gun, a drive motor mounted in the housing and electrically connected with the spray gun to pressurize the spray gun, and an electric storage unit mounted in the housing and electrically connected with the drive motor to supply an electric power to the drive motor. Thus, the spray gun injects atomized water outward to extinguish the fires easily and quickly.

Abstract: A versatile cleaning-used duster broom structure comprises a dusting broom body composed of elastic soft bristles to fit to a coupling seat equipped with a handle. The coupling seat has an opening end to which the dusting broom body is accommodated and located thereto. The opening end has multiple conjoining blocks each defined by an insert groove thereon, and the dusting broom body has the surface bundled up into a collecting portion so that the elastic soft bristles can be more evenly arranged to match to a fixing pole thereby. Besides, each elastic soft bristle has multiple individual cellular suction portions, forming an elastic and dense bristle surface thereon to suck up fine particles of dust thereby. Thus, via the stretchable character of the suction portions thereof, the elastic soft bristles can accurately enwrap trash and clean up sand, dust and hair, etc., providing effective and effortless cleaning benefit thereby.

Abstract: A sprinkling gun structure including a main body having two ends respectively formed with a water inlet and an adaptation hole. An assembling tunnel is transversely formed through the main body between the water inlet and the adaptation hole to communicate therewith. The sprinkling gun further includes an adjustment member, a controlling member having a water-checking section and a water intake, and a water-guiding member having a watertight sleeve fitted on bottom end of the water-guiding member. The controlling member is fitted in the assembling tunnel and rotationally drivable by the adjustment member. When driven, the water-checking section of the controlling member is rotated to cooperate with the watertight sleeve so as to shut off/turn on and micro-adjust the water flow.

Abstract: A cushion for a chair includes a cushion body (20) having a mediate position provided with a convex waist support portion (21), an upper end provided with an inclined backrest support portion (22) and a lower end provided with a concave resting portion (24). Thus, the backrest support portion and the waist support portion of the cushion body are designed to fit the user's back and waist ergonomically so that the cushion body can support the user's back and waist smoothly and exactly. In addition, the upper buffering space (202) and the lower buffering space (201) of the cushion body provide a buffering effect to allow deformation of the cushion body so as to regulate the user's seating posture and to provide a comfortable sensation to the user.

Abstract: A rotary spray nozzle for spray guns comprises a metallic outer housing and a plastic assembling element wherein the metallic outer housing has a hollow chamber disposed at one side to accommodate the plastic assembling element therein, a water-emitting port disposed at the other side to fluidly connect to the hollow chamber, and a ringed water-blocking seat protruding between the hollow chamber and the water-emitting port. The plastic assembling element, formed a hollow extending there-through, is molded similarly to the hollow chamber and equipped with an internal-threaded portion therein to secure to an external-threaded section defining a water-outlet cylinder of a gun body. The plastic assembling element also has a reverse-stop ring extending at the middle section to restrict the position of a sealing ring mounted to the water-outlet cylinder thereof, achieving anti-leaking and anti-loosing benefits as well as simplifying the structure and manufacturing process of the present invention thereby.

Abstract: A spray gun structure comprises a control valve mounted into an assembling chamber of a body and regulated by an adjusting device to control the on/off of water discharge thereby. A coupling sleeve is joined to the body with an abutment surface of a water-sealing sleeve abutting tight against a water-sealing area of the control valve, and protruding tracks engaged with guide recesses of a water-guiding element. A spray head having a connecting sleeve and a restrain collar mounted thereto is fitted to the body and screw-joined to the water-sealing element. The connecting sleeve is mounted to abut against the coupling sleeve, and the restrain collar has restrain blocks to restrict protrusions of the body. Therefore, when the spray head is pivotally rotated to and forth in its place, the water-guiding element can be synchronically actuated to move linearly forwards or backwards to verify the pattern of water spray thereby.
