Definitions

  • the present invention relates to spray guns for cleaning purposes and more particularly, to a rotary spray gun, which has a fluid and a flow of forced-air be mixed in a hard curved nozzle tip so that the hard curved nozzle tip is forced to rotate when spraying the fluid in the form of a mist of fine drops.
  • brushes, wipes, cleaning cloth, and/or many other cleaning tools may be used. Further, when washing a car, a forced flow of water may be applied. After washing of a car with a forced flow of water, a piece of cloth is usually used to dry and clean the car. This cleaning method takes much time and labor and consumes a big amount of water. To avoid these problems, rotary spray guns are created.
  • FIG. 7 illustrates a known design of rotary spray gun.
  • the rotary spray gun A comprises a grip A1, a T-pipe A2, a water container A3 and a nozzle assembly B.
  • the nozzle assembly B comprises a flared pipe B1 that has a fixed nut B11 located on its rear end and threaded onto the front end of a forced-air outlet port A4 at the front end of the T-pipe A2 of the rotary spray gun A, and a plastic rotary nozzle tube C, which has a connector C1 located on its rear end and connected to an inner thread in the forced-air outlet port A4 and a plurality of ring-shaped weight members C2 fastened to the periphery and spaced from one another along the length of the plastic rotary nozzle tube C.
  • the flow of forced-air flows through the T-pipe A2 toward the forced-air outlet port A4 to cause a Venturi effect in the T-pipe A2, thus water is sucked out of the water container A3 for mixing with the flow of forced-air in the forced-air outlet port A4.
  • the mixed water and forced-air is then forced out of the plastic rotary nozzle tube C for cleaning application.
  • the present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a rotary spray gun, which eliminates the drawbacks of the aforesaid prior art design.
  • a rotary spray gun comprises a control grip, which has an air hose connection located on the bottom side and connected to an external forced-air supply means for guiding in a flow of forced-air, a valve seat located on the top side and disposed in air communication with the air hose connection, a trigger pivoted to the valve seat for controlling output of the flow of forced-air through the valve seat, a connection tube horizontally forwardly extended from the valve seat, a water tube suspending in the connection tube, and an injection tube connected to a distal end of the connection tube, a fluid supply unit providing a fluid to the water tube, and a nozzle assembly fastened to a front connection end of the connection tube within the injection tube and connected to the water tube for directing the fluid out of the water tube.
  • the nozzle assembly comprises a nozzle tube sleeved onto the water tube and connected to the connection tube for guiding in the flow of forced-air from the external forced-air supply means, an adapter tube rotatably mounted on the nozzle tube by a plurality of bearings, and a hard curved nozzle tip connected to one end of the adapter tube and rotatable with the adapter tube for discharging the fluid out of the water tube and the flow of forced-air out of the nozzle tube.
  • a rotary spray gun in accordance with the present invention is shown comprising a control grip 1 , a fluid supply unit 2 and a nozzle assembly 3.
  • the control grip 1 comprises an air hose connection 11 located on its bottom side for the connection of an air hose of an external forced-air supply means for the inputting of forced air, a valve seat 12 located on its top side and disposed in air communication with the air hose connection 11, a trigger 13 pivoted to the valve seat 12 for controlling output of forced air through the valve seat 12 , a connection tube 14 horizontally forwardly extended from the valve seat 12 and terminating in a front connection end 141 , a water tube 15, which is concentrically mounted in the connection tube 14 and has its one end turned through 90-degrees and transversely extended out of the bottom side of the connection tube 14 and its other end suspending outside the connection tube 14 , and an injection tube 16 , which has one end connected to the front connection end 141 of the connection tube 14 and the other end terminating in an injection outlet 161 .
  • the injection tube 61 can be fastened to the front connection end 141 of the connection tube 14 by a screw joint, or by means of a tight-fit connection.
  • the fluid supply unit 2 comprises a fluid container 21 , a screw cap 22 capped on the top side of the fluid container 21, a control valve 23 installed in the screw cap 22 and kept in fluid communication with the water tube 15 in the connection tube 14 , a control knob 231 pivoted to the control valve 23 and operable to regulate the flow rate of the control valve 23 , and a dip tube 24 vertically downwardly extended from the control valve 23 and suspending in the fluid container 21.
  • the nozzle assembly 3 comprises a nozzle tube 31, which has its rear connection 311 located on its rear end and fitted onto the water tube 15 and press-fitted into the front connection end 141 of the connection tube 14 and a front connection 312 at its front end, an adapter tube 32 sleeved onto the front connection 312 of the nozzle tube 31, a plurality of bearings 35 mounted in the adapter tube 32 around the periphery of the front connection 312 of the nozzle tube 31 to support the adapter tube 32 on the nozzle tube 31 for allowing rotation of the adapter tube 32 relative to the nozzle tube 31, a spacer tube 33 sleeved onto the front connection 312 of the nozzle tube 31 within the adapter tube 32 and connected between the bearings 35 to kept the bearings 35 apart, a curved nozzle tip 34, which has a rear connection 341 fastened to one end, namely, the front end of the adapter tube 32 and connected with the water tube 15, and a retaining ring 36 fastened to the front end of the adapter tube 32 to
  • connection tube 14 connects to an external forced-air supply means (not shown), then connect the connection tube 14 to the valve seat 12 and the control valve 23 to keep the water tube 15 in fluid communication with the dip tube 24 in the fluid container 21 of the fluid supply unit 2, and then connect the rear connection 311 of the nozzle tube 31 of the nozzle assembly 3 to the front connection end 141 of the connection tube 14 to keep the curved nozzle tip 34 in fluid communication with the water tube 15 in the connection tube 14, and at final connect the injection tube 16 to the front connection end 141 of the connection tube 14 around the nozzle assembly 3 .
  • the control knob 231 when using the rotary spray gun, rotate the control knob 231 to adjust the opening degree of the passage between the dip tube 24 and the control valve 23, i.e., to regulate the flow rate of the control valve 23 .
  • the forced-air is guided through the air hose connection 11 and the valve seat 12 into the connection tube 14 and then the nozzle tube 31, the spacer tube 33 and the curved nozzle tip 34.
  • a Venturi effect is produced in the control valve 23, causing the fluid to be sucked through the dip tube 24 into the water tube 15 .
  • the forced-air causes rotation of the curved nozzle tip 34 with the adapter tube 32 in the injection tube 16 relative to the nozzle tube 31 due to the eccentric design of the curved nozzle tip 34 , and therefore the fluid that flows through the water tube 15 is forced out the injection outlet 161 of the injection tube 16 by the forced-air in a fine mist for removing dust from an object.
  • the curved nozzle tip 34 is made of a non-soft material, for example, metal or hard plastics, having high strength and toughness for long service life. Therefore, rotation of the curved nozzle tip 34 with the adapter tube 32 does not cause the nozzle tip 34 to break.
  • a brush 163 may be installed in an outer end edge 162 of the injection outlet 161 of the injection tube 16, as shown in FIG. 6 .
  • the injection tube 16 can be a flared tube with its injection outlet 161 expanding outward.
  • a water intake tube may be used to substitute for the aforesaid fluid container 21 and to guide water from an external water source to the control valve 23.
  • the invention provides a rotary spray gun, which has the following features and advantages:
  • FIGS. 1 ⁇ 6 A prototype of rotary spray gun has been constructed with the features of FIGS. 1 ⁇ 6 .
  • the rotary spray gun functions smoothly to provide all of the features disclosed earlier.
