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.
- the handset should be as simple and free as possible to move.
- the invention has for its object to provide a handheld device of the type described, which is easier to handle and more mobile.
- the hand-held device can be designed independently and without any supply lines of any kind. This results in a very convenient handling of the handheld device.
- the design of the pump as a vane pump according to pa claim 7 allows 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 8 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 divisible design of the housing according to claim 9 allows continuous use of the complex and expensive main part of the hand-held device containing the motor and the pump, the energy supply unit not being used being charged equally.
- the vane pump can advantageously be manufactured in the dimensions specified in claims 11 and 12, so that it can be installed in relatively thin hand-held devices 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 thus slightly smaller than the inner diameter of the housing 1, the outer diameter of which is max. is about 17 mm.
- the flight egg 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, a pressure change is generated during the rotation of the rotor 9 in accordance with the change in volume of each partial chamber closed by two slides 10 in the circumferential direction, which is transferred via the suction nozzle 5 and the hose connection 2 to the adapter 3 and thus to the opening area of a nozzle (not shown) placed on the adapter 3.
- the chamber housing 7 On the rear side of the vane pump 6 facing away from the adapter 3, the chamber housing 7 is closed off by a cover plate 11. On this cover plate 11, a motor 12 is flanged, through the drive shaft of the rotor 9
- Vane pump 6 is rotatable.
- the motor 12 is powered by a rechargeable battery 15 which can be charged via a charging socket 4 and to which it runs by means of a coupling pin 4
- Lines can be connected and which belongs to an energy supply unit 13, is supplied with energy.
- the accumulator 15 can have connections and a circuit board with a
- Potentiometer can be connected, the variable resistance of which can be set on a control knob. By adjusting the control knob, the speed of the vane pump 6 can be changed, and thus that of the opening area of the nozzle 2
- the vane pump is switched on and off using 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.
