Description

Portable individual air purification system

The present invention relates to a portable individual air cleaning system comprising an air filter device for a portable individual air cleaning device for cleaning ambient air and for discharging purified air, which air filter device comprises a filter housing, which filter housing defines a receiving space in which at least one filter element is accommodated, which receiving space of a Housing bottom and an outer circumferential, extending away from the housing bottom filter housing wall is limited.

Portable individual air cleaning system in the manner described above, are used in particular in areas with high levels of air pollution. A user can optionally cover his mouth and nose with a piece of clothing. Ambient air is cleaned with the air filter device received in the air cleaner and supplied to the user.

Usually air filter devices are arranged in such air cleaning systems difficult to access within a housing of the Luftreinigungsvorrich- device. An exchange of the air filter device is therefore usually cumbersome and time consuming.

It is therefore an object of the present invention to improve a portable individual air cleaning system of the type described above so that it is as easy to handle.

This object is achieved in a portable individual air cleaning system of the type described above according to the invention that the receiving space the housing bottom opposite to at least one air inlet opening is closed with a housing cover. Developing a portable individual air cleaning system in the described manner has the particular advantage that the air filter device can be arranged on the air cleaning device such that the air to be purified can flow directly through the at least one air inlet opening of the air filter device, without previously flowing through another opening of the air cleaning device to have to. Thus, stressed and to be cleaned air can be performed so in particular directly to the at least one filter element exclusively by the air filter device. Thereby, contamination of an air cleaning device for which the air filter device is designed can be minimized because only purified air can flow through the air cleaner. With an exchange of the air filter device, the entire contaminants filtered out of the air with the at least one filter element can thus be removed from the air cleaning system.

The air cleaning system can be handled in a simple manner if the air filter device is designed in the form of a filter cassette. For example, such a used filter element, which may be covered by the filter cassette, can be easily replaced and optionally also cleaned.

It is advantageous, in particular also in an air cleaning system of the type described in the introduction, if the air filter device is a filter carrier and if the at least one filter element is arranged or formed on the filter carrier. Such an air filter device is easy to handle for the user. In particular, so the filter element can be changed easily and safely, without it must be touched directly by a user. For example, the user can grasp the filter element via the filter carrier and remove it from the air cleaning device or even insert.

In order to increase the reliability of the air cleaning system, it is advantageous if the at least one filter element insoluble with the filter carrier connected is. Thus, in addition, a filter cassette which can be handled as a part by a user can also be formed in a simple manner.

Preferably, the filter support is dimensionally stable. In particular, the air filter device can be handled by a user in a simple and secure manner. In addition, it is thus also possible in particular to prevent the air filter device in the air cleaning device from being deformed in such a way that unfiltered air can flow from the air inlet to the air outlet.

A particularly compact design of the air cleaning system can be achieved in particular by the fact that the filter carrier comprises a filter housing. Thus, in particular, a filter element can be surrounded by the filter housing so that only those surfaces of the filter element are freely accessible through which contaminated air is to flow through the filter element.

A filter element can be particularly easily and safely arrange in a filter housing, if this comprises an annular housing bottom with a central opening and. In particular, such a pot-like filter housing can be formed. In addition, it is possible that the entire air to be cleaned must first flow through the at least one air inlet opening on the air filter device. Thereby, contamination of an air cleaning device for which the air filter device is designed can be minimized because only purified air can flow through the air cleaner. With an exchange of the air filter device thus the entire filtered out of the air with the at least one filter element pollutants can be disposed of.

It is advantageous if the housing cover and the filter housing are non-positively and / or positively connected with each other. For example, they can be glued together, screwed or welded. A connection can be made in particular after the insertion of the filter element in the filter housing. It is advantageous if the housing cover and the at least one filter element are sealed against each other and / or that the housing bottom and the at least one filter element are sealed against each other. In particular, it can be ensured that polluted air which has flowed into the air cleaning device through the air inlet can flow exclusively through the at least one filter element. This can be prevented in particular that contaminated air is conveyed through the air cleaning device to the user.

The at least one filter element can be arranged securely and protected in the filter housing if the filter housing comprises a support ring connected to the housing bottom via webs and if the at least one filter element and the support ring are sealed against one another. In particular, the support ring can be sealed against the housing cover or connected to this airtight, for example by gluing or welding.

It is advantageous if the portable individual air cleaning system comprises a garment for covering a user's mouth and nose, which garment is adapted for releasable connection to a portable individual air cleaning device for purifying ambient air and discharging purified air. In particular, an air space around the mouth and nose of a user can be formed by the item of clothing into which the air cleaned with the air-cleaning device can be directed. Thus, a user can breathe relatively freely, without having to have a caged feeling, as may be the case for example with tight-fitting gas masks and the like.

It is advantageous if the item of clothing has a clothing piece wall with a user facing the inside of the item of clothing and a piece of clothing outside the user, the item of clothing having a device receptacle for receiving the air purification device. In this way, the air cleaning device can be quickly and easily connected to the garment, namely lent by being inserted into the fixture receptacle. In particular, the air cleaning device can completely close the device receptacle so that no contaminated air can get into the air space formed by the garment around the mouth and nose.

Preferably, the garment comprises a mask and / or a scarf. A mask, in particular in the form of a face mask, which covers substantially only the mouth and nose of a user, can be made particularly small and compact. In particular, it can be carried independently of an outside temperature without the user having to sweat excessively. The same applies to a scarf. This may in particular be an open scarf with two free ends or even a self-contained scarf. In particular, both types of scarf described make it easy to cover the mouth and nose of the user, so that the portable individual air cleaning device can supply the user with purified air directly to the mouth and nose. Optionally, a combination of a mask and a scarf may be provided as a garment. In particular, both the mask and the scarf can be formed from a textile material in order to allow the user a high wearing comfort.

It is favorable if the device receptacle is arranged or formed on the mask and / or on the scarf. If the garment comprises only one mask, the device receptacle is formed on the mask. The same applies if the garment comprises only a scarf. If both a mask and a scarf are provided, the device receptacle can optionally be arranged or formed on the mask or on the scarf. Optionally, it can be formed both on the mask and on the scarf. In this case, the mask and scarf may in particular be worn so that the portable individual air cleaning device is placed on the scarf and the scarf covers the device opening on the mask, so that no unfiltered unpurified foreign air from the garment outside can get to the garment inside.

Preferably, the portable individual air cleaning system comprises a garment arranged or formed carrying means for attaching or hanging on at least one ear of the user. This allows the garment to be worn comfortably on the user's body. Optionally, the carrying device can also be attached to or hung on both ears of the user.

It is advantageous if the carrying device comprises at least one ear hook and / or at least one ear strap, which are designed to at least partially overlap and / or engage behind the at least one ear of the user. In particular, a high load comfort for the user can be achieved.

The air cleaning system can be carried particularly comfortably by a user if the ear carrier band is designed to be elastic or substantially inelastic. An elastic ear strap can be adjusted very well. Inelastic ear straps in particular allow a particularly defined arrangement of the garment on the ear of a user.

In order to avoid that uncleaned ambient air can reach the mouth or nose of the user, it is advantageous if the mask is formed from an at least partially dimensionally stable material. Thus, the mask can in particular be provided roughly adapted to a facial contour of the user. Basically, an individual adaptation of the mask would be possible.

Preferably, the mask is formed by press molding. This way, it can be trained in a simple and cost-effective way. It is advantageous if the mask and the scarf are permanently connected to one another. Thus, a defined arrangement of the mask in front of the mouth and nose of the user can be achieved, the scarf helps additionally to avoid that uncleaned ambient air can reach the inside of the garment piece.

In a simple way, the mask and the scarf can be connected to each other when they are sewn or glued together. Depending on the type of material from which the mask and the scarf are formed, so an optimal connection can be selected.

According to another preferred embodiment of the invention, it can be provided that the portable individual air cleaning system comprises a coupling device for coupling the mask and the scarf in a coupling position, which coupling device can be brought from the coupling position into a separating position in which the mask and the scarf are separated from one another are. In this way, mask and scarf can be separated, for example, for cleaning. In addition, the coupling device makes it possible to apply the mask and the scarf separately from each other and only when both mask and scarf occupy a position that is ideal for the user in front of the mouth and nose, connect to each other in a defined manner.

It is advantageous if the coupling device comprises at least one first coupling element which is arranged or formed on the mask and in the coupling position with the scarf force and / or positively engages and is disengaged in the disconnected position with the scarf. Thus, the air purification system can be formed in a particularly simple manner, since in particular when the scarf is suitable to be directly positively and / or positively engaged with the first coupling element, on a second coupling element, which is additionally arranged or formed on the scarf would have to be waived. The scarf itself forms in this case, as it were, a second coupling element of the coupling device.

It is advantageous if the coupling device comprises at least one second coupling element which is arranged or formed corresponding to the first coupling element on the scarf and with the at least one first coupling element in the coupling position non-positive and / or positive engagement and disengaged in the disconnected position , Regardless of whether the material from which the scarf is formed, is suitable for non-positively and / or positively engaged with the first coupling element in the coupling position, it allows at least one second coupling element, in a simple and defined manner to be brought into engagement with the at least one first coupling element in the coupling position.

It is favorable if the coupling device is designed in the form of a hook-and-loop fastener device, a snap connection device or a zipper connection device. This list is purely exemplary and not exhaustive. In particular, all the described types of connection make it possible in a simple and secure manner to connect the mask and the scarf in a defined manner.

Preferably, the snap connection device is designed in the form of a push-button connection device. Such a can be easily attached to the mask and the scarf, for example by sewing or riveting.

It may also be favorable if the at least one first coupling element is designed in the form of a first hook-and-loop fastener element, a snap-connection element or a zipper connecting element. In particular, the first hook-and-loop fastener element can be designed in the form of a hook-and-loop fastener tape, which can be brought directly into engagement with a scarf made of a knitted fabric. Optionally, the least at least one second coupling element may be designed to correspond, that is to say in the form of a second hook-and-loop fastener element, a further snap-fastener element and a further zip fastener element.

So that the scarf, for example, can easily and securely cover a lower edge or optionally also a device opening on the mask when it is coupled to the mask, it is favorable if the at least one first coupling element is arranged or formed on a mask outside of the mask.

Preferably, the at least one second coupling element is arranged or formed on a scarf inner side of the scarf. This makes it possible, in particular, for the at least one second coupling element to be brought into engagement in a simple manner with at least one first coupling element which is arranged or formed on a mask outside of the mask.

It can also be advantageous if the scarf forms the at least one second coupling element. This simplifies the production and thus also the production costs. In this case, no separate second connection element has to be connected to the scarf.

According to a further preferred embodiment of the invention, it may be provided that the scarf is formed from a scarf material, which engages with the at least one first coupling element in the coupling position. Selecting a corresponding formwork material thus has the particular advantage that the attachment or formation of a second coupling element on the scarf can be dispensed with.

It is advantageous if the item of clothing, in particular the piece of clothing, is formed from an air-impermeable material or from a material having a high air resistance. In particular, it can be prevented that contaminated, unpurified ambient air is removed by the tion piece, in particular through the garment wall, can enter into an interior defined by the garment, in which the mouth and nose of the user are arranged.

The air purification system can be designed simply and cost-effectively if the item of clothing, in particular the piece of clothing, is made of a textile material, in particular a woven fabric or a knitted fabric. The air cleaning system can thus be designed in particular with low weight and high comfort for the user. In particular, so the garment can be easily adapted optimally for a user. Conceivable here are in particular knitted fabrics in the form of so-called Fleece fabrics.

Conveniently, the garment is formed of a moisture permeable material from the garment inside to the garment outside. For example, moisture or perspiration contained in the air exhaled by the user may be drained from the interior through the garment.

In order to prevent the penetration of moisture into the interior of the item of clothing in a simple manner, it is favorable if the item of clothing outside is water-repellent or impermeable to water and / or coated. For example, the air cleaning system can also be worn when it is raining or when the ambient air has a high humidity and, in particular, condensation on the outer side of the clothing occurs.

It is advantageous if the garment is made of a UV-resistant material. Thus, especially for the garment selected colors can be obtained long-term stability. In addition, destruction of the garment by UV radiation can be prevented or at least delayed. According to a further preferred embodiment of the invention, it can be provided that the device receptacle is arranged or formed on a front side or a rear side of the item of clothing or laterally on the item of clothing. Depending on the individual preferences of a user, the appropriate garment can be selected. In particular, the position of the device receptacle also defines the position of the air cleaning device so that the location of the device receptacle also defines where ultimately the weight of the air cleaning device on the garment engages.

It is advantageous if the device receptacle is arranged or formed closer to a lower edge of the item of clothing than at an upper edge. Such an arrangement increases the wearing comfort, since in particular the weight of the air cleaning device engages deeper on the garment, so that it can be partially supported by the user neck, neck or shoulders and not completely, for example via an ear strap or an earhook on the ears of the user attacks.

Preferably, the device receptacle is formed in the form of a passage opening on the item of clothing. In particular, the passage opening may be circular or substantially circular. A passage opening can be produced in a simple manner. A circular or substantially circular through-opening makes it possible in a simple manner to arrange and fix the air-cleaning device in different orientations on the item of clothing.

In order to achieve an optimal adaptation of the garment, it is advantageous if the garment wall is flexibly deformable. In particular, it can cling well to a user's facial contour.

In order to achieve a particularly simple and secure connection between the garment and the air cleaning device, it is advantageous when the garment panel has an opening edge delimiting the device receptacle, and when the opening edge is inelastic or substantially inelastic, or when the opening edge is elastic. For example, an inelastic opening edge can be easily and securely clamped between suitable clamping surfaces on the air cleaner to secure the air cleaner to the garment. An elastic opening edge in particular has the advantage that it can be easily and safely inserted into a corresponding receptacle, for example into a circumferential groove which is open in the radial direction. If a free cross-section or a diameter of the device receptacle is smaller than a diameter of the receptacle on the air-cleaning device, the garment can thus be kept taut and secure in the receptacle due to the elasticity of the opening edge.

It is advantageous if the mask is formed of a mask material and if the mask material is stiffer than the formwork material. For example, it is thus possible to form a mask which is more dimensionally stable in comparison to the scarf so that the mask can, in particular, also permanently maintain a desired contour.

According to a further preferred embodiment of the invention it can be provided that the mask of a mask material and the scarf are formed of a scarf material and that the mask material and the scarf material differ. Thus, the mask and the scarf with different properties and optimal wearer comfort can be formed.

It is advantageous if the portable individual air cleaning system, in particular also one of the type described above, comprises a portable individual air cleaning device which comprises an air inlet for air to be cleaned and an air outlet for purified air. Such an air cleaning system makes it possible, in particular, to shield a user's mouth and nose from an environment. With the air purification device then ambient air can be cleaned and fed to the user via the air outlet.

The air cleaning system is easy to handle if the air cleaning device comprises a housing with the air inlet for air to be cleaned and the air outlet for purified air. Such an air cleaning device can be formed, for example, particularly compact.

Preferably, the air cleaning device comprises the air filter device. This makes it possible in particular to clean contaminated and polluted ambient air by the air filter device filters harmful and / or suspended solids from the ambient air, so that a user purified air can be supplied.

It is favorable if the housing has an air filter receptacle for receiving the air filter device. Thus, the air filter device can be arranged in a defined manner on the air cleaning device. Optionally, the Luftfiltereinrichtungsaufnahme also be closed, for example through the housing cover.

It is advantageous if the air filter device, in particular the housing cover, closes the air filter device receptacle. In particular, the housing cover can be positively and / or positively connected to the housing in a connection position. Furthermore, can be achieved by this development in particular also that the ambient air to be purified flows directly into the air filter device and only the purified air after flowing through the at least one filter element can come into contact with a flow path passing through the air cleaning device.

The air purification device can be made particularly compact if the air filter device comprises the housing cover. Thus, therefore, the air filter device and the housing cover form a unit. If the air filter device comprises a filter cassette, in particular the housing cover form part of the filter cartridge. This makes it possible, in particular, to replace the air filter device in a simple manner. There is no need to remove a separate cover to enable this. Rather, it is for example possible to easily detach the filter cartridge from the housing, in which case in particular the air filter device recording can be released.

It is advantageous if the air cleaning system comprises an edge holding device for non-positively and / or positively holding the device receptacle, in particular the opening edge, on the portable individual air cleaning device in a connecting position. In particular, the edge holding device enables a defined and secure connection of the item of clothing with the air cleaning device.

The edge holding device can be formed in a simple manner if it has a circumferential opening edge receptacle for at least partially receiving the opening edge. In particular, it can completely absorb the peripheral opening edge. If the opening edge is particularly elastic, it can be easily and safely inserted into the opening edge receptacle, for example into a circumferential groove which is open in the radial direction. If a free cross-section or a diameter of the device receptacle is smaller than a diameter of the opening edge receptacle, the garment can thus be kept taut and secure in the receptacle due to the elasticity of the opening edge.

The opening edge can be fixed in the opening edge receptacle simply and safely when the opening edge receptacle is designed in the form of a circumferential receiving groove.

A secure connection between the item of clothing and the air cleaning device can be achieved, in particular, by virtue of the fact that the opening edge in the opening edge receptacle is clamped in the connecting position. is held mend. In particular, garments of varying thickness can be easily and securely connected to the air cleaning device. For example, as an option, a connection between the air cleaning device and a mask or a scarf can be made.

Preferably, the edge holding device has at least two clamping surfaces facing each other, between which the opening edge is arranged or held in the connecting position. Thus, the opening edge can be easily and securely clamped on both sides between the clamping surfaces.

According to a further preferred embodiment of the invention can be provided that a first clamping surface of the at least two clamping surfaces on the housing of the air cleaning device is arranged or formed, that a second clamping surface of the at least two clamping surfaces on the air filter device, in particular on the filter cartridge, is arranged or formed and that the housing and the air filter device in the connecting position non-positively and / or positively connected to each other. This embodiment makes it possible, for example, to securely clamp the item of clothing, in particular its opening edge, between the two clamping surfaces, these being defined on the one hand by the housing and on the other hand by the air filter device. In particular, when the air filter device is formed by or comprises a filter cartridge, communication between the air cleaner and the garment can be easily achieved by connecting the air filter device to the housing, at least a part of which Air filter device and / or the housing passes through the device receptacle. A secure connection is achieved, in particular, in which the housing and the air filter device are non-positively and / or positively connected with each other. Thus, in particular, a distance between the clamping surfaces can be adjusted and thus a clamping force can be specified.

It is favorable if the air inlet comprises the at least one air inlet opening which is arranged or formed on the outer side of the clothing is. This makes it possible, in particular, to pick up polluted or contaminated ambient air through the air inlet from a garment outside and in particular to supply it to the user through the air outlet.

It is advantageous if at least one air inlet opening is open from the housing pointing away in a direction parallel to a transverse to a perpendicular to a protruding from the garment housing front side of the housing transverse axis. This makes it possible, in particular, to introduce ambient air directly from the front through the air inlet opening into the housing. In particular, a flow resistance of the air cleaning device can be minimized.

The air purification system can be made particularly compact if the at least one air inlet opening is annular. In particular, it may be designed in the form of an annular gap. In particular, so contaminated ambient air can be supplied to an annular air filter element from the outside, so that the contaminated air can flow through the filter element in the direction of its longitudinal axis.

It is advantageous if the air outlet has at least one air outlet opening, which is aligned in the connecting position in the direction of the mouth and nose of a user. This allows purified air to be delivered directly and simply to the mouth and nose of the user easily and safely.

It is advantageous if the at least one air inlet opening and the at least one air outlet opening are aligned transversely to one another. In particular, they can be oriented perpendicularly or substantially perpendicular to one another. In particular, contaminated air can flow from the front into the air purification device and be supplied to the user in a direction transverse thereto. A flow resistance of the air cleaning device can be minimized in a simple manner. In order to guide a defined airflow as accurately as possible to the mouth and nose of a user, it is advantageous if a free air inlet cross-sectional area defined by the air inlet is greater than a free air outlet cross-sectional area defined by the air outlet.

According to a further preferred embodiment of the invention, it can be provided that the air cleaning device comprises an air conveying device and that the air conveying device is designed to produce an unfiltered air flow from the air inlet to the air filter device and a filtered air flow away from the air filter device to the air outlet. In particular, the air conveyor may be arranged or formed upstream or downstream relative to the air filter device.

It is favorable if the air filter device and the air conveyor device are fluidically connected to one another and arranged or formed in the housing. Thus, in particular, a particularly compact air purification device can be formed overall. In addition, so air can be easily and safely conveyed away from the air filter device and from this.

In a simple and secure manner, ambient air can be cleaned and fed to a user's mouth and nose in a protected space defined by the garment when the air cleaner is received in the fixture receptacle. In particular, the air cleaning device can completely close the device receptacle.

It is advantageous if the air cleaning device is arranged and configured such that the air inlet is arranged or formed on the outer side of the garment and that the air outlet is arranged or formed on the inside of the garment. Thus, contaminated air may be taken into the air cleaner from the garment outside and supplied to the user on the garment inside through the air outlet after cleaning. In order to prevent polluted air from getting from the garment outside to the garment inside, it is favorable when the device receptacle is closed by the air cleaning device. Thus, ideally, there is only one flow path from the garment outside to the garment inside through the air purifier.

Conveniently, the air cleaning system comprises a power supply device for operating the air conveyor. In particular, this can be a network-independent energy supply device. Thus, the air purification system can be operated by a user completely independent of a power grid.

The air purification system can be designed in a particularly simple and compact manner if the energy supply device is designed in the form of a battery. In particular, it may be a rechargeable battery. In this way, the power supply device can be used several times, which increases the environmental friendliness of the air purification system.

The air purification system can be made particularly compact if the energy supply device is arranged in or on the housing.

In a simple way, an air flow can be generated when the air conveyor device comprises a motor-driven fan.

According to a further preferred embodiment of the invention it can be provided that the air cleaning system comprises a control and / or regulating device for controlling and / or regulating a volume flow of filtered air generated by the air conveyor. For example, a user can manually set the flow rate by default on the control and / or regulating device. However, a volume flow can also be adjusted automatically depending on environmental parameters and / or vital values of the user, for example, depending on a physical load of the user.

In order to activate the air cleaning system, it is advantageous if it comprises an actuating device for activating and deactivating the air conveying device. For example, the actuator may be actuated by the user or automatically activated in response to environmental parameters.

The housing cover preferably limits the air inlet in sections. Thus, the housing cover in particular protect the filter element or the air filter device as a whole and also lead the air flowing into the housing in a defined manner.

It is advantageous if the air filter device is positively and / or positively coupled to the housing in a coupling position. In particular, it can be ensured that the air filter device can not be detached from the housing in an undesired manner. In addition, it is optionally also possible to keep the garment between the air filter device and the housing, in particular by clamping. Alternatively, between the housing and the air filter device in the coupling position, a circumferential opening edge receptacle can be formed for receiving the opening edge. If the opening edge is particularly elastic, it can be easily and safely inserted into the opening edge receptacle, for example into a circumferential groove which is open in the radial direction. Is a free one Cross-section or a diameter of the device receptacle smaller than a diameter of the opening edge receptacle, so can keep the garment due to the elasticity of the opening edge simply and safely stretched in the recording.

It is advantageous if the air cleaning system comprises a coupling device for non-positive and / or positive coupling of the air filter device and the housing in the coupling position with each other. With such a coupling device, the air filter device and the housing can be interconnected in a defined manner.

The air cleaning system can be formed in a simple manner if the coupling device is designed in the form of a clamping connection device, a latching or snap connection device, a screw connection device or a bayonet connection device.

According to a further preferred embodiment of the invention, it can be provided that the air cleaning system comprises an air filter device detection device for detecting whether an air filter device is inserted into the air filter device receptacle on the housing or not. In particular, the air filter detection means may be configured to output a signal to the controller when an air filter device is inserted in the air filter receiver, so that the air conveyor can only be operated when an air filter device is inserted in the air filter receiver, and in particular in a specific and defined way.

It is favorable if the air filter device detection device is designed to detect whether the air filter device and the housing in the Coupling position are coupled together. In particular, it can be detected whether the air filter device is coupled to the housing in a defined manner. Only then, for example, can a signal be emitted from the air filter device detection device to the control and / or regulating device in order to activate the air conveyor device. Otherwise it can be deactivated.

In a simple way, it can be detected whether or not an air filter device is inserted into the air filter receptacle on the housing or not if the air filter device detection device comprises at least one detection element which is arranged or formed on the housing on or in the filter device receptacle. Thus, the presence of an air filter device in the air filter device receptacle can be detected in a simple manner in a contactless or mechanical manner.

The air purification system can be designed in a simple and cost-effective manner if the at least one detection element is in the form of an electronic switch or pushbutton or in the form of a magnetic sensor, in particular in the form of a Hall sensor. For example, an electronic switch or pushbutton may cooperate with a protrusion or return on the air filter device. A magnetic sensor can in particular interact with a magnet. In particular, the at least one detection element can cooperate with a position specification element which specifies in particular whether the air filter device is arranged on or in the air filter device receptacle or not.

It is advantageous if the air filter device detection device comprises at least one position setting element which is arranged or formed on the air filter device and cooperates with the at least one detection element in the coupling position. This makes it possible, for example, for the at least one detection element to be able to detect the presence of the air filter device in the air filter device recording, in particular, only if the at least one position specification element cooperates with the at least one detection element. In particular, a plurality of position specification elements may be provided to cooperate with one or more detection elements in the coupling position. Thus, in particular a plurality of different coupling positions between the air filter device and the housing can be specified. For example, this can be achieved with a coupling device which has an n-fold symmetry, in particular a two, three or fourfold symmetry.

In a simple manner, the air filter device detection device can be formed if the at least one position predetermining element is designed in the form of a magnet, a position predetermining projection, a position presetting recess or a position presetting section of the air filter device. In particular, a position specification section may be formed by a side surface or a bottom of the air filter device or a part thereof, respectively.

According to a further preferred embodiment of the invention it can be provided that the control and / or regulating device is formed cooperatively with the air filter device detection device or comprises the air filter device detection device and that the control and / or regulating device is designed such that the air conveyor device can only be activated when the air filter detection means detects that the housing and the air filter means are coupled together in the coupling position. This embodiment can in particular ensure that the air conveyor can only be activated when an air filter device is arranged in a defined manner on the housing and coupled with this in the coupling position.

It is advantageous if the air cleaning system comprises a radio interface device for communicating and / or exchanging data, in particular with the control and / or regulating device, with other devices, in particular with a computer and / or a smartphone. So The air cleaning system can be easily activated and deactivated by a user in a non-contact manner. In particular, depending on environmental parameters, it can also be activated or deactivated automatically, for example if pollutant concentrations in the ambient air exceed or fall below a certain limit.

According to a further preferred embodiment of the invention can be provided that the filter housing is open at the top and that the housing cover closes the filter housing at the top except for the air inlet opening which is formed between the housing cover and the filter housing wall. Thus contaminated air can flow into the filter housing between the housing cover and the filter housing wall and into the filter element in the filter housing.

A particularly compact construction of the air cleaning system can be achieved, in particular, by arranging or forming the at least one position presetting element on the filter housing, in particular on the filter housing wall. For example, a projection or a recess may be arranged on the filter housing. Optionally, a magnet may also be arranged on the filter housing.

The air cleaning system can be designed particularly cost-effectively if the filter carrier is made of a plastic. For example, such a filter carrier can be produced by injection molding.

A reliable cleaning of contaminated ambient air can be achieved, in particular, by the fact that the at least one filter element in the form of a pleated filter is formed with a plurality of mutually inclined filter element wall sections, wherein in particular the filter element wall sections extend parallel or substantially parallel to a longitudinal axis of the filter cassette. Further, a compact structure of the air cleaning system can be improved when the filter cartridge is disposed surrounding the electric motor in the housing. In particular, it is thus possible to achieve a substantially symmetrical design of the air purification device.

It is advantageous if the housing cover forms part of the housing front side. In particular, the housing cover can be arranged on an outer side of the item of clothing and thus be visible. For example, the housing cover may be designed to be semitransparent in order to allow luminous elements arranged behind the housing cover to be recognized. These may in particular illuminate in one or more different colors, for example to indicate an operating mode of the air cleaning device. For example, it may be a certain volume flow, which is funded by the air conveyor.

It is favorable if the air outlet defines an air outlet direction, if the air inlet defines an air inlet direction and if the air outlet direction and the air inlet direction are oriented transversely, in particular vertically, to one another. In particular, contaminated air can flow from the front into the air cleaning device and be discharged perpendicularly from the air cleaning device, in particular in a direction towards the mouth and nose of the user, when the air cleaning device is arranged according to the item of clothing.

It is favorable if the actuating device comprises an electrical switching element for activating and deactivating the air conveying device. In particular, a user can activate or deactivate the air purification device manually.

If the garment 12 comprises both the mask 50 and the scarf 52, the mask 50 may optionally comprise the device receptacle 46 as shown in FIG. 16. represents, comprise, or be formed without a device receptacle, as shown by way of example in Figure 17 or in Figures 1 to 6 schematically.

It is also possible in principle for a device receptacle 46 or 48 to be provided both on the mask 50 and on the scarf 52. For the intended use, it is then provided that the mask 50, when the air cleaning device 24 is disposed thereon, covers and closes the device receptacle 48 on the scarf 52. If, on the other hand, the air cleaning device 24 is arranged on the scarf 52, as shown schematically in FIGS. 1 to 6, the scarf 52 should intentionally cover and close the device receptacle 46 on the mask 50.

The garment 12 has a carrying device 54 for attaching or hanging on at least one ear 56 of the user 18 is arranged or formed. In the case of the air cleaning system 10 exemplified in the figures, the carrying device 54 comprises two ear straps 58. Alternatively, one or more ear hooks may be provided instead of the ear straps 58.

Both the ear straps 58 and the earloops are configured to be disposed on one or both ears 56 of the user 18 by at least partially engaging or engaging one or both ears 56. This is shown by way of example in FIGS. 1 and 3.

The ear straps 58 are arranged laterally on the mask 50 in the embodiments shown in the figures. If the garment 12 does not comprise a mask 50, it may also be arranged or formed on the scarf 52.

For a high wearing comfort the ear straps 58 are preferably formed elastically. Alternatively, they may also be substantially inelastic to allow for a defined positioning of the garment 12 on the head 60 of the user 18. In order to allow the best possible adaptation of the mask 50 to a facial contour of the user 18, the mask 50 is formed of an at least partially dimensionally stable material.

For example, the mask 50 can be made of a neoprene material, in particular by press molding, in order to achieve a contour that is as close as possible to the head 60 of the user 18 in the area above the nose 16.

The mask 50 and the scarf 52 may be permanently connected to each other, for example by sewing and / or gluing.

FIGS. 1 to 6 show by way of example a coupling device 62 for coupling the mask 50 and the scarf 52 in a coupling position shown schematically in FIGS. 1 to 4 and 6. The coupling device 62 can be brought from the coupling position into a separating position shown by way of example in FIG. 5, in which the mask 50 and the scarf 52 are completely separated from one another.

The coupling device 62 is formed in the embodiment schematically illustrated in the figures in the form of a Velcro connection device 64.

Alternatively, instead of or in addition to the Velcro connection device 64, a snap connection device or a zipper connection device for connecting the mask 50 and the scarf 52 may also be provided. The snap connection device can be designed in particular in the form of a push button connection device, in which the two interacting parts of the push button connection device are arranged or formed on the mask 50 on the one hand and on the scarf 52 on the other hand.

The coupling device 62 may comprise one or more first coupling elements 66, which are arranged or formed on the mask 50. examples For example, the first coupling element 66 may be formed in the form of a first hook-and-loop fastener element 68.

If the coupling device 62 is designed in the form of a snap connection device or a zipper connection device, the at least one first coupling element 66 is correspondingly designed in the form of a snap connection element or a zipper connection element.

The first coupling element 66, in particular if it is designed in the form of a first hook-and-loop fastener element 68, can engage in force and / or in a form-fitting manner, in particular in the coupling position, directly with the scarf 52. In this case, the scarf 52 forms a second coupling element. For example, this embodiment can be provided when the first hook-and-loop fastener element 68 comprises a plurality of hook-type hooks and the scarf 52 is formed from a formwork material which can hook directly to the hook-type hook. In this case, the scarf 52 is thus formed from a scarf material which engages with the at least one first hook-and-loop fastener element 68 in the coupling position.

Regardless of the formwork material from which the scarf 52 is formed, the coupling device 62 may comprise one or more second coupling elements 70, which are formed corresponding to the first coupling element 66.

The at least one second coupling element 70 can, as shown in particular in FIGS. 5 and 6, be arranged or formed on the scarf 52. It is in the coupling position with the at least one first coupling element 66 non-positively and / or positively engaged, as shown by way of example in Figure 6.

The second coupling element 70 can, as shown by way of example in FIGS. 5 and 6, be designed in the form of a second hook-and-loop fastener element 72 or, depending on the form in which the coupling device 62 is formed, as a second snap connection element or second zipper connecting element.

The at least one first coupling element 66 is arranged or formed in the embodiment of an air cleaning system 10 shown schematically in FIGS. 1 to 6 on a mask outer side 74 of the mask 50. On the other hand, the at least one second coupling element 70 is arranged or formed on an inner side of the scarf 76 of the scarf 52, so that the mask 50 and the scarf 52 can be coupled to one another in an overlapping manner.

The garment 12, particularly the garment panels 32 and 34, is preferably formed of an air-impermeable or at least high-drag material. In this way it can be prevented that polluted ambient air can flow into an interior space 78, which is formed in the intended use of the air cleaning system 10 between the garment 12 and a face 80 of the user 18.

The garment 12, in particular the garment walls 32 and 34, are preferably formed from a textile material. This can be, in particular, a woven fabric or a knitted fabric, ie a so-called knitted fabric. In particular, a knitted fabric, for example in the form of a so-called fleece material or fleece fabric, is particularly suitable for forming a scarf 52, since this material can be used as a second coupling element 70 for connecting to a first hook-and-loop fastener element 68 comprising a plurality of hook-and-loop fasteners. to couple the mask 50 and the scarf 52 together in the coupling position.

The wearing of the garment 12 can be made particularly pleasant for the user 18, when the garment 12 from a for Moisture from the garment inside 36, 38 to the garment outside 40, 42 permeable material is formed.

The garment outer side 40, 42 may also optionally be water-repellent or impermeable to water and / or coated.

For a good durability of the air cleaning system 10, it is advantageous if the garment 12 is formed of a UV-resistant material.

The device receptacle 46 or 48 is always arranged on the front side 82 and 84 of the mask 50 and the scarf 52 in the embodiments illustrated in the figures. Alternatively, the device receptacles 46 and 48 can also be arranged or formed on a rear side of the item of clothing 12 or laterally thereon. An arrangement on the back is particularly suitable for a scarf 52 surrounding the head 60.

The scarf 52 may optionally be formed in the form of a self-contained tube scarf. Alternatively, it may be formed in the form of a scarf with two free ends 86.

If the mask 50 and the scarf 52 are formed separately from each other, an optimal fit of the garment 12 to the head 60 and a contour of the face 80 can be achieved when the mask 50 is first applied. In a second step, the scarf 52 equipped with the air-cleaning device 24 can then be placed around the head 60 and the neck 88 of the user 18 so that overall a particularly comfortable carrying situation for the user 18 can be achieved. The described method of putting on the item of clothing 12 additionally allows individual adaptation of the mask 50 on the one hand and of the scar 52 on the other hand to the head 60 or a contour of the face 80 of the user 18. The device receptacles 46 and 48 may in particular, as in the embodiments shown schematically in the figures, be arranged or formed closer to the lower edge 90 or 92 of the mask 50 or of the scarf 52 than on an upper edge 94 or 96 of the mask 50 or of the scarf 52nd

The device receivers 46 and 48 are formed in the form of through holes 98 and 100, respectively, with a circular or substantially circular free cross section.

The garment walls 32 and 34, in particular those of the scarf 52, are flexibly deformable.

The device receptacles 46, 48 are each bounded by an opening edge 102 and 104, respectively. For optimal coupling between the garment 12 and the air cleaning device 24, the opening edge 102 is preferably inelastic or substantially inelastic. This means, in particular, that a circumferential length defined by the opening edge 102 or 104 can not change or only insignificantly.

The mask 50 is preferably formed of a mask material, the scarf 52 of a scarf material, wherein the mask material and the scarf material may differ from each other or be identical. For example, the mask material may be a neoprene material or another thermoplastically deformable plastic material, the scarf material a textile material as described above. Preferably, the mask material is stiffer than the scarf material so that the scarf 52 can be more individually conformed to the head 60 of the user 18 than the mask 50.

The air cleaning system 10 may in particular also include the air cleaning device 24. This comprises an air inlet 106 for polluted and to be cleaned ambient air 26 and an air outlet 108 for purified air 28.

The air inlet port 130 and the air outlet port 140 are aligned transversely to each other. This allows a flow of ambient air 26 into the air cleaning device 24 through the air inlet 106 in a direction transverse, in particular perpendicular to a direction in which the purified air 28 flows out of the air cleaning device through the air outlet 108.

A free air inlet cross-sectional area defined by the air inlet 106 is preferably larger than a free air outlet cross-sectional area defined by the air outlet 108.

Due to the described embodiment of the filter cartridge 22, the housing cover 128 limits the air inlet 106.

The filter housing 116 is open at the top or on a front side, so that the housing cover 128 closes off the filter housing 116 except for the air inlet opening 130. This is formed between the housing cover 128 and the filter housing wall 124, in particular between the sleeve wall section 138, which is encompassed by the filter housing wall 124.

The first and second coupling elements 166 and 168 are non-positively and / or positively engaged in the coupling position. In a disconnected position, as shown by way of example in FIG. 8, the coupling elements 166 and 168 are disengaged, that is, they are separated from one another.

In the air cleaning system 10 exemplified in the figures, three first coupling elements 166 are provided and formed in the form of coupling recesses 170. Further, three corresponding second coupling elements 168 are formed in the form of coupling recesses 170 corresponding to the coupling projections 172. The coupling projections 172 extend at a circumferential angle of about 120 ° offset on the outside of the filter housing wall 124 and extend substantially in the circumferential direction.

The coupling recesses 170 are formed on the air filter device receptacle 126 on a wall surface of the housing 110 substantially concentrically surrounding the longitudinal axis 152. They each have an insertion region 174, so that the air filter device 20 can be inserted parallel to the longitudinal axis 152 in the Luftfiltereinrichtungsaufnahme 126 until the coupling projections 172 engage in the coupling recesses 170. By rotating the air filter device about the longitudinal axis 152 by an angle which substantially corresponds to an angle over which the coupling projections 172 extend in the circumferential direction, the air filter device 20 is positively and / or positively coupled to the housing 110 in the coupling position.

Alternatively, it is also possible to form the first coupling element in the form of a coupling projection and the second coupling element in the form of a coupling recess.

Instead of the coupling recesses 170 and the coupling projections 172, thread sections corresponding to one another may be provided on the air filter device receptacle 126 and on the filter housing 116 in order to screw the air filter device 20 to the housing 110.

Another possibility for non-positive and / or positive connection of the air filter device 20 and the housing 110 may consist in particular that mutually engageable, corresponding latching or snap elements are formed, on the one hand to the air filter device 20 and the other part of the housing 110 in the area the air filter device receptacle 126 are arranged or formed.
