Definitions

  • the invention relates to a hand-held device for generating local negative or positive pressure according to the preamble of patent claim 1.
  • Such handheld devices serve a wide variety of purposes, e.g. the handling of small and smallest objects, such as components from electronics, optics, laboratory and medical technology.
  • the handset should be as simple and free as possible to move.
  • a hand-held device for generating local negative or positive pressure in which a housing is provided on which an adapter is arranged and in which a pump which is connected to the adapter via a line , a motor, by means of which the pump can be driven, and an energy supply unit, by means of which the motor is supplied with energy, are arranged.
  • the case points a section designed as a handle, by means of which the hand-held device can be handled.
  • the invention has for its object to make this handheld device convertible and mountable in a simpler manner.
  • the housing of the hand-held device is so divisible between the motor and the power supply unit that its portion containing the energy dispensing unit can be dismantled from the rest of the housing and replaced by another portion containing a charged power supply unit.
  • This divisible design of the housing permits continuous use of the complex and expensive main part of the hand-held device containing the motor and the pump, the energy supply unit that is not in use being charged at the same time.
  • the design of the pump as a vane pump according to claim 2 enables a particularly simple and lightweight design of the pump and thus a particularly low weight of the handheld device.
  • the vane pump has proven itself to be ideally suited for the desired purposes.
  • a particularly space-saving accommodation of the motor within the hand-held device is possible according to claim 3 by flange-mounting the motor on the vane pump.
  • the handheld device is easily adaptable to a wide variety of possible uses without any particular effort.
  • the vane pump can advantageously be produced in the dimensions specified in claims 5 and 6, so that it can be installed in relatively thin hand tools or handles without problems.
  • the hand-held device shown in the figure has a housing 1.
  • An adapter 3 is provided at the front end of the housing 1.
  • This adapter 3 is connected via a line or hose connection 2 arranged in the interior of the housing to the suction port 5 of a vane pump 6.
  • the outer diameter of the vane pump 6 is 13.5 mm and is therefore slightly smaller than the inner diameter of the housing 1, whose outer diameter max. is about 17 mm.
  • the vane pump 6 has a chamber housing 7 in which a chamber is formed.
  • the chamber is arranged eccentrically around a rotor 9 which is provided at regular circumferential intervals with slots running in its axial direction, in each of which a slide 10 is slidably mounted in the radial direction.
  • each slide 10 lies with its outer edge against the chamber wall. Due to the eccentric course of the chamber wall with respect to the rotor 9, when the rotor 9 rotates, a pressure change is generated in accordance with the change in volume of each partial chamber closed by two sliders 10 in the circumferential direction, which change via the suction nozzle 5 and the hose connection 2 to the adapter 3 and thus is transferred to the opening surface of a nozzle, not shown, placed on the adapter 3.
  • the chamber housing 7 is closed off by a cover plate 11.
  • a motor 12 is flanged to this cover plate 11, through the drive shaft of which the rotor 9 of the vane pump 6 can be rotated.
  • the motor 12 is supplied with energy by an accumulator 15 which can be charged via a charging socket 14, to which it can be connected by means of lines running through a coupling pin 4 and which belongs to an energy supply unit 13.
  • the accumulator 15 can be connected via connections and a circuit board to a potentiometer, the variable resistance of which can be set on a control button. By adjusting the Control knob, the speed of the vane pump 6 can be changed and thus the power prevailing at the opening surface of the nozzle 3 can be controlled.
  • the vane pump is switched on and off at an on / off switch 14.
  • the illustrated and described embodiment of the hand-held device has a maximum outer diameter of 17 mm and a length of 155 mm.

Abstract

Un outil manuel pour la production de dépression ou de surpression locale présente un boîtier sur lequel est prévu un raccord, une pompe reliée au raccord par l'intermédiaire d'un conduit, un moteur assurant l'entraînement de la pompe, et une source d'énergie alimentant le moteur. En vue de faciliter la manipulation et la mobilité d'un tel outil, il est proposé que la pompe et le moteur soient logés à l'intérieur du boîtier de cet outil.

Claims (10)

  1. Appareil tenu à la main pour produire une dépression ou suppression locale, comprenant un boîtier (1) sur lequel est prévu un embout adaptateur (3), une pompe (6) qui est reliée par une conduite (2) à l'embout adaptateur (3), un moteur (12) par lequel la pompe (6) peut être entraînée, et une unité d'alimentation en énergie (13) par laquelle le moteur (12) est alimenté en énergie, la pompe (6), le moteur (12) et l'unité d'alimentation en énergie (13) étant disposés à l'intérieur du boîtier (1) de l'appareil et ce dernier étant réalisé sous la forme d'une poignée, caractérisé par le fait que le boîtier (1) de l'appareil tenu à la main peut être subdivisé, entre le moteur (12) et l'unité d'alimentation en énergie (13) de telle manière que son tronçon contenant l'unité d'alimentation en énergie (13) puisse être démonté du boîtier restant et être remplacé par un autre tronçon contenant une unité d'alimentation en énergie (13) chargée.
