Definitions

  • the present invention relates to a cleaning gun, in particular a pneumatic cleaning gun.
  • the rotary type pneumatic spray cleaning gun uses high pressure air to suck the liquid inside the liquid container through the liquid extraction hose so that the liquid is mixed with the high pressure air and further sprayed outside through the nozzle. This increases the cleaning capacity on the vehicle.
  • the pneumatic spray cleaning gun with a rotating mechanism with vacuum suction capability also has an air intake opening for sucking in the dust. Since the air inlet opening, the liquid inlet opening and the air suction opening all therefore require an external connecting hose to be connected to the container that provides the air or the liquid, the number of openings to be joined is greater without the composition of the external connecting hoses changing should change. It is therefore one of the problems to be solved by the designer how to make the assembly of the pneumatic spray cleaning gun with rotating mechanism with the external connecting hoses more practical.
  • a cleaning device for cleaning surfaces is previously known by providing at least one gaseous, pressurized pressure medium and at least one cleaning active cleaning medium for turbulence in a nozzle assembly of the cleaning device by means of a rotating nozzle arrangement.
  • the novelty of the invention is that a pneumatic cleaning gun is provided which increases the practicality of the assembly between the pneumatic spray cleaning gun with rotating mechanism and the external connecting hoses.
  • a pneumatic cleaning gun has a gun housing with a compressed air connection, a liquid nozzle with a nozzle jacket and an air suction pipe which on the one hand opens into the jacketed flow channel and on the other hand can be connected to a suction device via a suction hose in order to suck off dirt particles through the flow channel.
  • the suction hose can interfere with work if it interferes with the intended cleaning work.
  • the invention overcomes this disadvantage by improving a cleaning gun in that the air intake pipe is not rigidly attached to the cleaning gun, but is pivotable.
  • the air intake pipe can therefore be brought into several different positions of use, so that the user can choose the most comfortable or expedient position of use and adjust the air intake pipe accordingly.

  • the jacket sleeve can rotate in relation to the mounting sleeve.
  • the second positioning structure can optionally be in one of the first Snap in the positioning constructions so that the air intake pipe has several positions of use.
  • the pneumatic cleaning gun according to the above-mentioned embodiment is divided into two sections by the nozzle casing.
  • One section is a rigidly attached mounting sleeve
  • the other section is a rotatable jacket sleeve.
  • the latter can be connected to the air intake pipe of the casing sleeve and rotated into the required rotational position. It follows from this that not only can the practicality of mounting the air intake pipe on the cleaning gun be increased, but rather a disruption of the cleaning process by the air intake pipe can be avoided.
  • the pneumatic cleaning gun disclosed in another embodiment includes a gun body, a nozzle jacket, and a swivel tube.
  • the gun body includes a gun body, a handle, and a liquid nozzle.
  • the handle and the liquid nozzle are each connected to the two opposite sides of the gun body.
  • the nozzle jacket is attached to the gun body of the gun body.

  • the pneumatic cleaning gun shows a rotary connection tube which can be rotated in relation to the connecting pieces.
  • the rotary connection tube can be rotated into the position preferred by the user and thus assembled with the outer connection channels.

However, the positions are not limited to these two; In other exemplary embodiments, the rotary connection tube 300C can also have three or more positions of use (e.g. also a position of use with an air intake opening 321 directed upwards).
  • the nozzle jacket 200 is rigidly attached to the gun housing 100, and the swivel tube 300C rotates relative to the gun housing 100 Nozzle jacket 200.
  • the nozzle jacket 200 can also rotate relative to the gun housing 100, the rotary connection tube 300C being rigid on the nozzle jacket 200 is attached.
  • Figure 16 is a three-dimensional view of a detail of how the nozzle jacket is attached to the gun body, as shown in the second embodiment of this invention.
  • Figure 17 is a detailed representation of the nozzle casing from Figure 16 .
  • the nozzle casing 200a from this exemplary embodiment comprises a mounting sleeve 210a, a joint sleeve 220a, a flow disturbance sleeve 230a and a deflection sleeve 240a.
  • the mounting sleeve 210a envelops the liquid nozzle 130, the end being attached to the gun body 110 of the gun housing 100.
  • the articulated sleeve 220a envelops the fluid nozzle 130 and is also rotatable at the opposite end of the assembled sleeve 210a.
  • the joint sleeve 220a and the mounting sleeve 210a can be rotated with respect to one another.
  • the diameter of the annular conical surface is smaller the further it is away from the gun body.
  • the flow disturbance sleeve 230a comprises an outer ring 231a and an inner ring 232a, which are connected to one another.
  • the outer ring 231a surrounds the inner ring 232a and is attached to the end of the joint sleeve 220a which faces away from the assembly sleeve.
  • the outer ring 231a and the joint sleeve 220a may be fixed to each other by gluing, or the outer ring 231a and the joint sleeve 220a may be directly shaped and constructed as one body.
  • the deflection sleeve 240a is detachably attached to the end of the nozzle casing 230a which faces away from the joint sleeve 220a. It should be noted that the deflection sleeve 240a and the nozzle casing 230a can also be shaped and constructed as one body.
  • One end of the rotary connection tube 300a has an air intake opening 310a, the other end of the rotary connection tube 300a is connected to the joint sleeve 220a, so that the rotary joint pipe 300a can rotate through the joint sleeve 220a along the direction shown by arrow c in relation to the gun housing. Therefore, in this exemplary embodiment as well, by means of the rotatable connection tube 300a which can be rotated in relation, the rotation connection tube 300a can be rotated to the position preferred by the user in order to install the outer connection hose. This makes it more convenient to mount the outer connecting hose on the pneumatic cleaning gun.
  • the inner ring 232a of the deflection sleeve 230a is rigidly fastened in the interior of the outer ring 231a.
  • this is not restricted to this form, but rather in other exemplary embodiments the inner ring 232a of the deflection sleeve 230a can also be attached in a rotatable manner in the interior of the outer ring 231a.
  • the rotary connecting tube 300a can be rotated to the position preferred by the user by the relatively rotatable rotary connecting tube in order to install the outer connecting hose. This makes mating the outer connector hose with the rotatable pneumatic spray cleaning gun more convenient.
