Definitions

  • the invention relates to a device for Ver ⁇ spray of pressurized fluids supplied to the outside with the free end portion "of the liquid keitszu enclosureskanals ange- ⁇ rdneten adjustable nozzle for forming different Ausströmungsart.
  • Devices of this type for example for spraying fragrances, insecticides, disinfectants or the like, are sufficiently known, the nozzle being rotatably mounted relative to the liquid supply channel in order to form, for example, a full jet or a spray jet.
  • the object of the invention is to improve a device of the type specified in the preamble of claim 1 in such a way that a substantial simplification of the setting of the desired type of transmission can be achieved; the risk of contacting the medium to be sprayed should at least be reduced.
  • a rod is provided which is adjustable along the liquid supply channel and which is led out at the end facing away from the nozzle from the liquid supply channel in a sealing manner and one outside the liquid supply channel Has adjustment handle.
  • the end of the liquid supply channel is arranged.
  • the respective position of the rod carrying the handle relative to the liquid supply channel and thus the respective setting of the nozzle can be clearly recognized a priori. It is advantageous if the rod of the handle and / or on the liquid supply channel or on the housing of the device are arranged symbols which identify the respective setting, which results in a further simplification of handling.
  • a design which is both favorable in terms of production technology and long-lasting is characterized in that an annular sealing seat is arranged in the liquid supply channel, through which the rod is penetrated with play, into which the closure body to block the liquid supply channel, the closure body arranged on the rod is designed so that it can be gripped, preferably also an elastically flexible sleeve is arranged as a closure body, which in particular also tapers approximately conically in the closing direction.
  • nozzle in the liquid supply channel is mounted such that it can be adjusted axially and in a tightly closing manner, and that it can be retracted into the liquid supply channel by means of the rod, and in particular that the free end face of the rod at least approximately abuts against the drainage plate. lying. is arranged.
  • FIG. 1 shows a device for spraying liquids in front view
  • Fig. 2 likewise partially broken open, in the spray position
  • Both embodiments have a housing 1 in common, the connection piece 2 of which can be connected in a tightly closing manner to a liquid container (not shown). Furthermore, a piston pump (not shown) is arranged in the housing, which is operated manually via a handle 3 and by means of which liquid can be conveyed from the connected liquid container under pressure into a liquid supply channel 4 arranged in the housing 1.
  • Both embodiments also have an adjustable nozzle 5 arranged in the front end part of the liquid supply channel 4 for forming different outflow types, and a rod 6 which is axially displaceable in the liquid supply channel 4 and serves as an adjusting member for the nozzle 5.
  • the latter with the end part facing away from the nozzle 5, protrudes tightly from the cylindrical liquid supply channel 4 and carries an adjusting handle 7 on its projecting end part.
  • closure body 9 is fixed, the z ⁇ m Ver ⁇ close the liquid supply duct 'is 4 in a diameter reduced and forming a valve seat area 4 'of the liquid supply channel 4 can be adjusted.
  • a swirl plate 10 is also formed on the inside of the nozzle 5, which is followed by a channel 11, which is opposite the flow direction of the medium and widens conically, in which the rod 6 can engage with play on the circumference.
  • the nozzle 5 is fixed flush in the liquid supply channel 4 with its front end side, and the rod 6 is realistically axially limited to the nozzle 5 so that the end face of the rod 6 facing the nozzle 5 is in one End position (FIG. 2) bears against the swirl plate 10, while in the other end position (FIG. 4) the aforementioned rod end is outside the nozzle channel 11 and at the same time the liquid supply channel 4 is blocked by the closure body 9. While the in Fig. 2 d . position of the rod 6 results in a spray mist, a full jet is generated with the position of the rod 6 shown in FIG. 3.
  • symbols 12 which cooperate with the adjusting handle 7 and which indicate the respective setting of the nozzle or the position of the valve which can block the liquid supply channel 4 are arranged on the housing 1.
  • the respective switching positions can be made tangible by means of surmountable locking means arranged on the mutually adjustable parts.
  • the nozzle 5 in the liquid supply channel 4 is delimited along its length and is adjustably closed in a sealing manner, and is fastened to the end part of the rod 6 facing the nozzle 5, so that the nozzle 5 is carried along when the rod 6 is adjusted.
  • the nozzle 5 is flush with the front end face of the liquid supply channel 4. In this case, the liquid supply to the nozzle 5 is released and the liquid is sprayed by means of the nozzle.
  • the nozzle 5 is adjusted with the handle 7 together with the rod 6 from the aforementioned position into the position shown in FIG. 6 and thereby drawn into the liquid supply channel 4, the front opening area of the liquid supply channel 4 forms for the Spray mist leaving nozzle 5, which cause a further dissolution and foaming of the liquid.
  • the foaming effect can be further enhanced by depressions arranged in the aforementioned mouth region.
  • the nozzle 5 is sealed in the liquid supply channel 4 by means of a sleeve-like ring seal 13 formed on the rear end of the nozzle 5.

Abstract

Dispositif pour la projection à l'air libre de liquides alimentés sous pression, comportant une buse disposée à l'extrémité libre du canal d'alimentation du liquide afin d'obtenir différents types d'écoulement, amélioré pour permettre une simplification substantielle du réglage du type d'écoulement pressurisé souhaité. Cette amélioration est obtenue par le montage le long du canal d'alimentation de liquide (4) d'une tige disposée de manière réglable (6) et servant de régulateur pour la buse (5), cette tige sortant de manière étanche du canal d'alimentation de liquide (4) situé à l'extrémité opposée de la buse (5), et une commande (7) manuelle réglable étant située à l'extérieur du canal d'alimentation de liquide (4).
