- FIG. 6 shows the air-conducting funnel 30 in which an engagement protection element 40 is arranged at the outlet opening 32 of the air-guiding funnel 30 in a perspective view.
- Fig. 7 is a plan view of the Luftleittrichters 30 is shown with Eingreifschutzelement 40.
- Fig. 8 shows the Luftleittrichter 30 with Eingreiftikelement 40 in a sectional view taken along the line CC of Fig. 7.
- an additional material 50 is disposed, the odor-neutralizing and odor-masking substances containing the Suction air stream 16 are discharged and fight odors.
- the odor-neutralizing substances are delivered in the form of clathrates in the suction air stream 16, the clathrates were purchased through the company "et-project” with the trade name "SinoAir®".
- This ingredient consists mainly of plant clathrates.
- the active ingredient is combined with essential essences in a gel derived from vegetable substances. As a result, the use can be realized up to one year.
- the odor-masking substances are emitted as perfume substances into the suction air stream 16, which gives the air a lemon odor.
- a filter element 60 which is in a replaceable filter cartridge, the air duct 20 in the direction of the suction air flow 16th upstream. Through the filter element 60, the suction air stream 16 can be freed of residual dust to protect the motor-fan unit 15 from contamination.
- the present invention enables the provision of a vacuum cleaner with an interventional protection element which can prevent the user from engaging in dangerous parts such as the fan blades by simple constructive and inexpensive means.
- the resistance opposed to the suction air flow by the engagement protection element can be reduced. This is achieved by the surface elements of the Eingreiftikelements are formed propeller blade-like.
- a compact design can be achieved.
