- the mode of operation consists in the fact that the resonant circuit of the resonant circuit arrangement 20 excited by an excitation switch (not shown) emits electromagnetic waves to the outside.
- the AC voltage signals generated due to the vibrations in the electronic circuit are rectified in the rectification arrangement 21, so that a signal is present at the output thereof which is dependent on the amplitude of the vibrations.
- the comparator arrangement 20 containing two comparators it is checked whether this signal is smaller than its first threshold value S 1 and at the same time larger than a second, lower threshold value S 2 . Only when these two conditions are met, the triac 23 is switched to conduct current, so that the vacuum cleaner motor 24 can be switched on by means of a manual switch (not shown).
- the first threshold value S 1 is set so that the output signal of the rectification arrangement 21 is higher when the resonant circuit arrangement 20 is not damped, so that the triac 23 is blocked.
- the sensitive element 5 or 18 comes into the effective range of the resonant circuit arrangement 20 and is induced by voltage in the sensitive element 5 or 18 Eddy currents are generated which withdraw energy from the resonant circuit and dampen it.
- the oscillation amplitude thereby decreases, so that the output signal of the rectification arrangement 21 also decreases.
- the two threshold values S 1 and S 2 are set so that the damping of the resonant circuit arrangement 20 generated by the sensitive element 5 or 18 in the correctly installed state of the additional filter 1 or connecting piece 11 is just sufficient to reduce the output signal of the rectification arrangement 21 below the upper one To press threshold S 1 , but not below the lower threshold S 2 so that the intended condition is met and the triac 23 is switched to the current-carrying state, so that the vacuum cleaner motor 24 can be switched on or operated.
- the threshold value S 1 would not be fallen below and the vacuum cleaner could not be operated.
- the comparator arrangement could 22 also have only one comparator, so that only checked is whether a sensitive element 5 or 18 with a certain Minimum size in or on the additional filter 1 or connector 11 is included.
- a triac 23 a other known electrical or electronic switches to step.
- the connector 11 is a schematic Shown top view.
- four different sensitive elements 25 - 28 arranged: three sensitive Elements 25 - 27 in a rectangular shape with different Areas and a sensitive element 28 in the form of a double stripe.

- Each of the The resonant circuit arrangements 29-33 are thereby determined Damped way, the resonant circuit arrangement 33 no damping experiences. This is shown in comparator arrangements, not shown checked, and only if the intended damping value everywhere is detected, the triac 23 is turned on.
- the number and arrangement of the sensitive elements and resonant circuit arrangements can of course be chosen practically arbitrarily become.
- FIG. 4 An arrangement corresponding to FIG. 4 can of course be used also on one or, if available, on several additional filters 1 may be arranged, for example on a frame or housing an additional filter. The mode of action is then corresponding the description of FIG. 4.
- Circuit for checking a correct additional filter or filter bag or connector there is a sensor device from a transmitter 34 and a receiver 35 for electromagnetic Waves.
- One to be attached to the additional filter 1, for example sensitive element 36 is designed as a microchip and also consists of a receiver 37 and a transmitter 38 for electromagnetic waves.
- Power supply device 39 for the receiver 37 and the Transmitter 38 is provided, which is either designed as a battery or which are connected to the resonant circuit of the receiver 37 and the supply voltage from the RF energy received in the resonant circuit wins, as for example from DE 41 10 683 is known.
- a converter is contained in the receiver 37 or in the transmitter 38, by which the received signal is changed. This changed The signal is then transmitted by the transmitter 38 of the sensitive element 36 back to the receiver 35 of the sensor device.
- the conversion can be done, for example, by that the frequency or phase of the RF signal is changed.
- the retransmitted can Signal can be modulated in a certain way, so that a certain code sent to the receiver 35 of the sensor device becomes.
- the signal received in the receiver 35 is then in one Decoder 40 then checks whether the intended information of the sensitive element 36 is included. Is this the If so, the decoder 40 switches the triac 23 in a current-conducting manner. Further possibilities of signal coding and retransmission by sensitive elements 36 designed as microchips known from DE 41 10 683 already mentioned.
- the transmitter for electromagnetic waves as the light transmitter and the receiver trained as a light receiver for electromagnetic waves is.
- a barcode or another can then be used as a sensitive element Appear device that changes the light in or unchanged Way to the light receiver of the sensor device returns.
- a light guide can be provided, which on a Place light received by the sensor device on another Leads back to the additional filter or connector, on which the light receiver is arranged.
- the sensitive element in turn as a current-conducting plate or metallic surface element may be formed, the one Forms part of a capacitor of a resonant circuit.
- the sensor devices and evaluation devices can be integrated or non-integrated Circuits on the circuit board 6 and 19 may be included.
- the entire circuit fully or partially to form an integrated circuit or there can be several sensitive elements at different Make multiple circuit boards or other sensor devices be provided.
- a sensitive element or several sensitive elements arranged on the actual filter bag 10 be who usually clings to the walls during operation creates a filter bag space in the vacuum cleaner.
- the circuit board 19 and / or an integrated Sensor and evaluation circuit can be arranged. They are too combined versions possible, some of which are sensitive Elements on the actual filter bag 10 and some on the connector 11 are arranged. Of course, this applies also for additional filters.
