- FIG. 1 An embodiment of a stand-alone vacuum cleaner 10 as an example of a suction device, which is shown schematically in Figure 1 in a sectional view, has a dirt collecting container 12, on which a suction head 14 is placed.
- the vacuum cleaner 10 is designed as an autonomous device.
- the dirt collecting container 12 has a suction inlet 16 to which a suction hose 18 can be connected in the usual way.
- the suction head 14 seals the dirt collecting container 12 on the upper side and forms a suction outlet 20, on which a filter device 21 with (at least) a first filter 22 and a second filter 23 is held.
- a suction line 24 Connected to the second filter 23 is a suction line 24, via which the dirt collecting container 12 is in flow connection with a suction unit 26.
- the suction unit 26 comprises an electric motor 25 and a blower device 27 with an impeller 28 rotatably driven by the electric motor 25.
- the dirt collecting container 12 is subjected to negative pressure during the operation of the vacuum cleaner 10 by the suction unit 26, so that a suction flow represented by the arrows 30 in FIG. 1 is formed. Under the effect The suction flow 30 can be sucked with dirt-laden suction air through the suction inlet 16 into the dirt collecting 12, which can then be sucked by the suction unit 26.
- the suction air can from the
- Suction unit 26 are discharged via exhaust ports 29 of the suction head 14 to the environment.
- the suction air flows through the filters 22 and 23 and entrained solid particles are deposited. It is therefore necessary to clean the filter device 21, which has a dirty side 32, from time to time, since otherwise forms an increasing flow resistance, whereby the suction effect of the vacuum cleaner 10 is impaired.

It comprises a stationary in the suction head 14 arranged valve holder 36 which forms a valve seat for a movable valve body in the form of a valve plate 38.
- the valve plate 38 is acted upon by a closing spring 40 with a closing force in the direction of the valve holder 36.

- This particular (preferably as well as the closing spring 40) has a linear characteristic. It is for example designed as a helical spring.
- the stop spring 44 is not under tension in the closed position of the valve disk 38. Only when the valve plate 38 lifts off from the valve seat of the valve holder 36, the stopper spring 44 comes to rest on the underside of the valve plate 38 and is in another Be Movement of the valve plate 38 slightly compressed. It thus exerts an increasing restoring force on the valve disk 38 and accelerates the movement of the valve disk 38 from its closed valve position (shown in FIG. 2) back to the closed valve position via an open valve position. In the open valve position, the valve plate 38 takes a distance to the valve holder 36, which forms the valve seat.

- the electromagnet 50 is connected via a power supply line to an (electronic) control device arranged in the suction head 14 in electrical shear connection. From the controller, the electromagnet 50 is supplied with a supply current during the normal suction operation of the vacuum cleaner 10. Due to the forming magnetic field of the valve plate 38 is reliably held in its closed position. The holding force of the electromagnet 50 is supported by the spring force of the closing spring 40.
- the magnetic holding force acting on the valve disk 38 is eliminated and the valve disk 38 becomes due to the pressure difference acting on it, resulting from the external pressure of the outside air present in the region of the valve holder 36 and the internal pressure within the suction line 24 results, lifted against the action of the closing spring 40 from the valve seat.
- External air can then flow abruptly through the passage openings of the valve holder 36 into the suction line 24 and the filter device 21 is abruptly acted on its clean side 48 with external air. This leads to a mechanical vibration of the filter device 21.
- the filter device 21 flows in countercurrent direction, that is to say counter to the direction of flow 30 prevailing during the normal suction operation, as a pressure pulse by external air. This results in an effective cleaning of the first filter 22 of the filter device 21.

- the housing 134 is open downwardly via a first opening 138 and upwardly via a second opening 140.
- the first opening 138 serves for a fluid-effective connection with the first filter 22.
- the second opening 140 serves for a fluid-effective connection with the suction unit 26.
- the second housing 134 has a contact region 142 on the housing 122 of the first filter holder 72.
- an intermediate element 144 (corresponding to the intermediate element 114) for fixing to the housing 144 of the second
- Filter holder 74 is provided.
- the first filter holder 72 and the second filter holder 74 form "single cassettes" for the first filter 22 and the second filter 23, which can be stacked on the abutment region 142 and positioned on the suction device 10.
- the suction device 10 functions with such a first filter holder 72 and second filter holder 74 the same as described above. It is also possible that, for example, the second filter holder 74 is positioned on the suction head 14 and (subsequently) the first filter holder 72 is positioned on the second filter holder 74. Further, it is possible, for example, that first the first filter holder 72 is positioned on the second filter holder 74, and then this combination is positioned on the suction head 14 or the dirt collecting container 12.
