- the tank 4 display a fill level for the liquid, For example, have a viewing window 33, which also with Markings not shown can be provided.
- the housing of the drive part 1 takes an electric motor 7 for a blower 8 and batteries 9.
- a pump 10 is provided, which is electrical can be operated by the batteries 9 or manually.
- a hose line 11 is attached to the outlet of the pump 10, the other end of which is provided with a coupling element 12.
- a valve 13 is provided which a Emptying of the tank 4 prevented when uncoupling.
- the drive part 1 contains two arranged upstream of the blower 8 Air outlet openings 14.
- One in the area of the handle 3 attached, combined switching element 15 is used alternately or joint actuation of the motor 7 and the pump 10. Instead one combined switching element 15 can also be two Use separate electrical switches.
- the suction part 2 consists of a hollow suction housing 16, the releasably on the drive part 1 by means of two snap locks 17 is attached.
- the suction housing 16 has an air inlet 18 and an open end on the drive part 1 for attachment is pushed. Is between the air inlet 18 and the blower 8 a filter element 19 is arranged in front of which there is a water separator 32 is located. This water separator 32 prevents known Way that moisture, for example, from the applied to the ground Detergent liquid gets into the drive part 1.
- the hollow suction housing 16 has a channel 20 for receiving the Hose line 11, which can be closed by a cover 21.
- the cover 21 has a receptacle for the in the hollow suction housing 16 located part of the coupling element 22 and a nozzle holder 23 with integrated spray nozzle 24.
- the handheld vacuum cleaner is equipped with a provided in the front part opening 26.
- the spray nozzle 24 has a spray opening 27 for fan-shaped, point-shaped or conical Application of the cleaning liquid 28.
- the spray nozzle 24 produces a satisfactory despite only a slight overpressure Application of the cleaning liquid 28.
- the tank 4 For operating the battery-operated hand-held vacuum cleaner according to the invention the tank 4 through the opening 5 with a cleaning liquid filled.
- the suction part 2 is by means of the snap locks 17 attached to the drive part 1.
- the two parts of the hose line 11 are connected by the coupling elements 12 and 22.
- the switching element 15 is actuated for suction. Now the detergent are applied, the switching element 15 becomes corresponding actuated so that the pump 10 is driven and the cleaning liquid 28 through the hose 11 through the spray opening 27 of the spray nozzle 24 is sprayed.
- the pump lever can be operated. If the spray extraction is interrupted, so the valve 25 ensures that the detergent liquid not dripping.
- the hand vacuum cleaner sucks both dry dirt as well as liquids and the detergent on.
- the drive part 1 and the suction part 2 when the hand vacuum cleaner is switched off can be separated by opening the snap locks 17. In doing so at the same time the coupling elements connecting the hose line 11 12 and 22 separately, wherein the valve 13 is an expiry of in the tank 4 detergent liquid prevented.
- FIG. 4 shows a special suction nozzle 29 according to the invention shown, which if necessary in the air inlet 18 of the suction part 2 can be inserted.
- FIG. 5 shows a top view of the Suction surface of the suction nozzle 29, which has a small opening 30, which is surrounded by two rubber lips 31, so that the only slight Vacuum of the hand vacuum cleaner is reinforced.
- This special Suction nozzle 29 for cleaning textile and hard, smooth surfaces of all kinds is able to suck in water despite a slight negative pressure, so that only a small residual moisture on the surface remains.
- the spray nozzle satisfactory output despite only a slight overpressure of the detergent causes a low pressure valve dripping prevents a clutch in the handheld vacuum cleaner for the spray extraction line that the handheld vacuum cleaner is provided is able to suck in water despite low vacuum and / or that the liquid tank is above the pump during operation.
