Definitions

  • the invention is based on fog machines, which have at least one evaporator.
  • Fog machines are generally known in the art.
  • a fog machine makes artificial fog by evaporating fog fluid.
  • the known from the prior art smoke machines consist of a pump which promotes the fog fluid from a tank in an evaporator with pressure.
  • a heating element is arranged to heat the evaporator housing and the fluid.
  • the fluid evaporates as a result of the heat supply, whereby it expands very much.
  • the evaporator accordingly has a line connection, via which the mist fluid passes from the pump into the evaporator.
  • a fluid line is arranged, in which the fluid can sometimes be heated to the gas phase.
  • the fluid line ends at a nozzle. Due to the expanded fluid and the high pressure build-up, the fluid is forced through the nozzle. Outside the fog machine, the fluid condenses into small droplets, which then form the mist
  • a disadvantage of the evaporators known from the prior art it is therefore that the fluid lines can almost no longer be maintained and cleaned.
  • the heating elements can not be replaced in the event of a defect, since they are firmly cast in the aluminum block. With blocked fluid lines or defective heating resistor, the evaporator must be replaced.
  • the object of the present invention is to provide an evaporator for fog machines, with the improved accessibility of the fluid line and the heating element is achieved.
  • Another object of the present invention is to provide a simpler evaporator that can be manufactured via simpler and less expensive production methods.
  • the evaporator in particular for a smoke machine, has an evaporator housing with a fluid inlet and a fluid outlet. Fluid inlet and the fluid outlet are connected to each other via a fluid line, is arranged in the evaporator housing.
  • the present invention is characterized in that the fluid line is formed from at least two fluid sub-lines which break through at least one outer surface of the evaporator housing, wherein the openings are closed by at least one closure plate.
  • the outer surface is meant the entire enveloping surface of the evaporator housing. This means that the fluid line can also end in a hole that is open to the outside.
  • the bore is defined by the outer peripheral surface.
  • the evaporator according to the invention thus has at least four openings.
  • the evaporator housing is broken at least at two further point of the fluid line. This leads advantageously
  • the fluid line can be cleaned via the further openings on the evaporator housing.
  • the fluid line breaks through the evaporator housing at a plurality of diametrically opposite points. This leads to the advantage that, for example, in a rectangular construction of the evaporator fluid lines can run parallel to each other and at right angles to the side surfaces.
  • the fluid lines can be realized by simple holes perpendicular to the side surfaces. The openings are then closed by the closure plate according to the invention. Clogged the fluid line at one point, the closure plate can be removed by a simple screw and the fluid lines are cleaned in the simplest way. The fluid lines are easily accessible and can be cleaned by a suitable drilling or broaching method. A complex and costly casting process is avoided otherwise.
  • the fluid lines run meander-shaped in the evaporator housing.
  • the meandering arrangement of the fluid lines has the advantage that the smoke fluid has to travel a longer distance in the evaporator. As a result of the longer path, the fluid is heated evenly and there is more chance that the fluid expands. As a result of the uniform heating and expansion, a uniform mist is created at the nozzle outlet.
  • the closure plate of the fluid line is formed so that a deflection of the fluid from one sub-line takes place in another sub-line.
  • Particularly advantageously opens the breakthrough of a single fluid sub-line in a connecting cavity into which also opens a breakthrough of another fluid sub-line.
  • a deflection device for example in the form of a plug, can be introduced into the connection cavities.
  • the deflection device has a recess (cavity) designed in such a way that the fluid can flow from one fluid sub-line to the next.
  • the deflection device can be connected in advantageous embodiments by means of a screw or press connection with it. This leads to the advantage that an ideal fluid flow is achieved.
  • a seal of the housing openings of the evaporator with respect to the outside world can be achieved, since the seal via the separate deflecting device and the closure plate takes place.
  • a sealing compound in the form of high-temperature-resistant silicone or a rubber or Teflon seal is arranged between the evaporator housing and closure plate.
  • seals of different metals, aluminum, copper and / or bronze can be used.
  • At least heating elements in a recess formed separately from the fluid line are arranged in the evaporator housing.
  • the heating elements are just resistance elements in the holes, casually blind holes can be introduced. This leads to the advantage that a defective heating element in the simplest way disassembled again, ie can be taken out of the evaporator housing. In conventional evaporators spiral coils are used, the assembly due to the pouring into the aluminum block is virtually impossible.
  • the evaporator housing is made of aluminum.
  • Aluminum has the great advantage that it is lightweight and easy to work with.
  • aluminum offers a high thermal conductivity.
  • the evaporator housing can also be formed in two parts.
  • the one part of the fluid lines, d. H. the lower half can be placed in the lower block and the other half in the upper block. This leads to the advantage that both aluminum blocks are easy to work.
  • the fluid lines can be introduced by milling process.
  • the two housing parts can be interconnected by simple connection mechanisms such as writing or gluing.
  • FIG. 1 shows an evaporator 1 with an evaporator housing 2.
  • a fluid line 4 is formed, which is also formed of a plurality of mutually parallel fluid sub-lines 4a.
  • the Evaporator housing 2 has a fluid inlet 5 and a fluid outlet 6.
  • the evaporator housing further has an outer surface 7.
  • a fluid connection 15 is arranged on the evaporator housing 2.
  • the fluid connection 15 serves to allow the supply of the fluid into the fluid line 4 and, moreover, to provide a connection possibility for an external fluid line, for example a hose. A simple coupling of a hose is thereby possible.
  • Fluid can be supplied from the pump via a pump, not shown, and a hose, not shown, of the fluid line 4 via the fluid port 15.
  • the fluid connection 15 can be screwed into the evaporator housing 2, glued or already covered by the evaporator housing.
  • a nozzle 10 is further arranged.
  • the nozzle 10 can preferably be screwed into the evaporator housing 2 via a thread.
  • Other connection alternatives such as welding, gluing, etc. are of course also possible.
  • the fluid line 4 extends perpendicular to the fluid inlet 5, wherein other arrangements of the fluid line are possible.
  • the fluid line 4 breaks through the evaporator housing at a plurality of diametrically opposite points, wherein the fluid sub-lines 4a extend parallel to one another and at right angles to the side surfaces 17.
  • the breakthroughs 8 formed thereby are open to the outside and open into picturshohl continuu18.
  • the fluid line 4 is a total and are the associated fluid sub-lines 4a very easy to access and clean from the outside.
  • the fluid sub-lines 4a can be cleaned with brushes.
  • the fluid line 4 is dimensioned so that, depending on the fluid to be conveyed, sufficient heating is achieved over the entire conveying path, so that the fluid has reached the gas phase at the latest at the fluid outlet 6.
  • the openings 8 are closed by two closure plates 3 so that no fluid escapes.
  • deflecting devices 9 are arranged in the form of plugs in the connecting cavities 18.
  • the plugs 9 have cavities through which the fluid can flow from one into the other fluid part line 4a.
  • the closure plate 3 is screwed by screws 14 to the evaporator housing. As shown, a seal for better sealing can be arranged between the closure plate 3 and the evaporator housing 2.
  • the deflection device 9 is pressed via the closure plate 3 in the Ardsholraum 16, in which case the closure plate 3 and the deflection device 9, the evaporator housing 2 seals substantially outwardly.
  • the deflection device 9 can be inserted, pressed or screwed.
  • the fluid line 4 runs as shown in FIG Figure 1 to 3 as closely as possible to the heating elements 12 enclosed by the evaporator housing 2.
  • the heating elements 12 serve to heat the fluid up to the gas temperature and are formed in separate Bankelementausnaturalept 17 in the evaporator housing 2.
  • the evaporator housing 2 and the closure plates 3 are preferably made of aluminum.
  • Aluminum has the advantage that it is relatively easy to work and has a high thermal conductivity.
  • other alloys and materials are conceivable.
  • FIG. 3 shows a arranged on the evaporator housing bimetal switch 14, which turns on and off the pump in dependence on the temperature in the evaporator housing 2.
  • a temperature sensor may be arranged on the evaporator housing 2, the pump power being controlled as a function of the determined evaporator housing temperature.
  • the evaporator according to the invention can be supplied with fluid particularly advantageously via a central pump unit, wherein a plurality of evaporators according to the invention can be connected in parallel.
  • a central pump unit supplies as many evaporators according to the invention as provided for the respective application, wherein the respective individual evaporator according to the invention can be activated or deactivated in a further advantageous embodiment of the invention via a switching unit.
  • the switching unit can be provided instead of the bimetallic switch, which then comprises at least one temperature sensor.
