Definitions

  • This invention relates to a nozzle construction and in particular to a nozzle construction with a load element and a spray element.
  • the pressure spray gun or air spray gun is connected by a T-piece to a handle, a liquid cylinder and a nozzle, and the bottom of the handle is connected to an air compressor by a hose.
  • the handle regulates the high-pressure air from the air compressor into the T-piece, so that the liquid is pressed out of the liquid cylinder and then sprayed outwards through the nozzle.
  • the pressure spray gun or air spray gun has only a small spray range. If a user wants to carry out a large-scale cleaning at high speed using the pressure spray gun or air spray gun, it is easy due to the rapid flushing process that a part of the area to be cleaned is skipped so that this area remains uncleaned. As a result, it takes a lot of time for the user to repeatedly clean the same area until an optimal cleaning effect can be achieved. The developers therefore had to solve the question of how the overall cleaning power of the pressure spray gun can be improved overall.
  • the present invention represents a nozzle construction with which the underlying technical problem of the insufficient general cleaning power in the air spray gun is solved.
  • An example of the present invention relates to a nozzle construction for spraying air at a high flow rate and a liquid, which comprises an air flow tube, a rotating unit, a load element, a spray element, a jet tube and a liquid flow tube.
  • the air flow tube has an air flow channel in which the air circulates at a high flow rate.
  • the rotatable rotation unit is attached to the air flow pipe.
  • the load element is mounted on the rotary element to increase the weight of the rotary unit and its torque.
  • the spray element is fixed to the rotation unit.
  • the jet pipe is attached to the rotation unit, which has a jet channel and is connected to the air flow pipe.
  • the air flow channel is connected to the jet channel.
  • the jet channel has an outlet end and a jet channel at the outlet end.
  • the jet channel and the axis of the air flow tube are at an acute angle to one another.
  • the liquid flow tube has a corresponding liquid inlet end and a liquid outlet end.
  • the liquid inlet end is outside the air flow tube, and the liquid outlet end passes through the air flow tube into the air flow channel, the air flow channel extending to the outlet end of the jet channel, whereby the liquid emerges from the liquid outlet end and is mixed with air at a high flow rate for nebulization.
  • the air is sprayed at a high flow rate from the air flow channel towards the outlet end, so that the outlet end rotates relative to the axis due to the eccentric force from the jet pipe. While the rotation unit is rotating, the spray element is also rotated so that an air flow is formed.
  • the outlet end is in the flow path of the air flow.
  • the spray element and the load element are installed together on the rotary unit, and the spray element and load element are driven so that they rotate as soon as the air flows through the jet pipe at a high flow rate .
  • the rotating spray element generates an air flow and this flows from the spray element to the outlet end in order to increase the nebulizing effect of the liquid and the air at a high flow rate, or else it flows from the outlet end to the spray element in order to absorb the contaminants adjacent to the outlet end.
  • the load element increases the load of the rotary unit, so that the torque of the rotary unit is increased. In this way, the general cleaning power of the nozzle construction can be further improved in the arrangement of the spray element and the load element.

  • the connecting pipe body 43 is to be connected to the air flow pipe 10.

  • the high flow rate air flows through the jet duct 41 to the outlet end 411, the high flow rate air simultaneously generates a reaction force to the outlet end 411. Because the outlet end 411 is not on the axis P and the discharge path A is not is parallel to the axis P, when the reaction force acts on the outlet end 411, the outlet end 411 is in an eccentrically loaded state, so that the beam 40 drives the rotary element 30 to rotate together.
  • the discharge path A is at an acute angle ⁇ to the axis P of the air flow pipe 10, and the outlet end 411 is moved circularly around the axis P during the rotation of the jet 40.

  • the load element 70 is, for example, a compression spring; the load element 70 is attached to the second end of the rotation unit 30 and covers the jet pipe 40 in order to increase the load of the rotation unit 30 and thereby in turn increase the torque of the rotation element 30.
  • the arrangement in the present exemplary embodiment, in which a compression spring serves as the load element 70, is not intended to restrict the present invention. In other embodiments, other components such as tapes can be used.
