Description

Respirator

The invention is based on a respiratory protection mask for the respiratory protection of a mask wearer, with a mask body and at least one filter for filtering a fluid, preferably air, flowing through the mask and / or the mask body.

Filtering half masks are mask and filter in one. In the case of known half masks, the filter can usually not be replaced. Rather, these half masks are completely disposed of after use or when the filter is exhausted. Half masks are usually relatively light and comfortable to wear, have a relatively large filter surface and are relatively hygienic. The disadvantage is that conventional half masks are generally more expensive to use than full masks and are usually not suitable for filtering gaseous pollutants.

Half masks are often used as occupational safety, e.g. in the medical field to protect against infections, but also e.g. when working with dust, wood, fiberglass or concrete, have a mask body, usually made of rubber or silicone, and encompass the mouth and nose of a mask wearer . In some embodiments, one or two filter cartridges can be attached to the mask body.

A half mask of the type mentioned is known from DE 40 17336 C1. The known half mask has a half mask body with a sealing edge which is inserted into a filter holder. A filter is attached to the filter holder in the mouth area. The filter holder extends from the mouth area to the cheek area of the half-mask body and rests freely on the half-mask body. Inhalation takes place through an inhalation valve, and exhalation runs through an exhalation valve, which is buttoned into the half-mask body in the chin area is. A strap with which the half mask can be attached to the head of an equipment wearer is fastened in an eyelet of the filter holder.

In the known half mask, the tightness between the oral cavity and the environment is determined by the geometry and rigidity of the sealing edge, the flexibility of the half mask body and the lateral support of the half mask body by the filter holder. A soft mask body or soft sealing edge increases the wearing comfort, but worsens the mechanical stability, while a high rigidity of the mask body or the sealing edge is perceived as uncomfortable when the half mask is worn.

The filter holder resting on the half mask body in the cheek area only brings about a certain lateral stabilization of the half mask body, while there is no direct interaction between the filter holder and the sealing edge, which is decisive for the tightness of the half mask.

A half mask known from GB-PS 761 263 consists of a flexible half mask body in which a filter holder with a filter is inserted in the mouth area. In the area of the sealing edge of the half mask body, a wire helix is vulcanized into the mask body in order to give the sealing edge a corresponding rigidity. The wire helix can be roughly adapted to the face contour of the mask wearer.

Although the known half mask is given increased rigidity in the area of the sealing edge due to the wire helix, the half mask can only be worn by a specific mask wearer because of the individually curved wire helix. This makes handling more difficult in practical use, since after the device has been reprocessed, the individual preformed half masks have to be returned individually to the mask wearer. The invention is based on the object of improving a half mask in such a way that, in addition to being comfortable to wear, it also has a high degree of tightness for different face shapes and has particularly good filtering of a fluid flow flowing through the mask.

Brief description of the invention

The object is achieved in that a) the mask body has a cutout and / or b) the mask body has at least one support means which, when the mask is in place, is arranged at least in the cheek area and / or in the nose area of a mask wearer; and / or c) the at least one filter at least one or more from heating coil, biofilter and / or moss, moisture storage, airgel, gel foam, activated carbon, salt water filter, labyrinth filter and / or labyrinth, UV filter and / or UV radiator, electrical and / or an electrostatic filter, membrane filter and / or particle filter.

The UV filter or the UV radiator can have at least one UV radiation source, for example a UV-C radiation source, which can be designed, for example, as an LED.

The shape of the mask or the mask body can be flexible due to the cutout. The mask can thus be adapted to the face shape of a mask wearer be adjusted. By means of the support means, the mask can be adapted to the face shape of a mask wearer. The proppant can increase the mechanical stability of the mask. The support means can have a former with which the mask can be brought into a shape adapted to the face shape of a mask wearer. Depending on the fluid to be filtered or the substances to be filtered out of the fluid, the filter can be suitably selected.

The mask can be a half mask. The mask body can be a half-mask body. The mask according to the invention can be suitable for filtering or killing germs, bacteria and / or viruses, for example corona viruses or influenza viruses, from the air to be inhaled by the mask wearer. In this way, the mask can protect the mask wearer from infections or respiratory diseases, for example. For this purpose, the mask can have at least one suitable filter, e.g. as described below. It can also be provided that the mask alternatively or additionally contains particles, e.g. fine dust (e.g. filters with PM 2.5 to PM50) or exhaust particles, car exhaust, volatile organic compounds, formaldehyde, asbestos, harmful smoke gas components or smoke particles, smoke odors, pollen, animal hair, fungal spores , Dust mite excrement, NOX can filter out of gas or air. The mask can have a filter suitable for this.

The mask body can have a cutout. The cutout can preferably have a V-shape or the like. In this way, when the sides of the cutout are brought together and preferably connected to one another, the mask can be converted from an essentially two-dimensional shape into an essentially three-dimensional shape. The cutout can preferably be arranged essentially in a chin area and / or mouth area of a mask wearer when the mask is put on. The three-dimensional shape can correspond to a face shape of a mask wearer. The sides of the cutout can each have a sealing lip. Thus, in the applied state, when the sides of the cutout are brought together, the sealing lips can be in engagement with one another and / or contact and / or overlap. A flow of a fluid through the sealing lips can thus be blocked in at least one flow direction.

The mask wearer can have a support means. When the mask is in place, the support means can be arranged at least in the cheek area and / or in the nose area of a mask wearer. The support means can be designed in the cheek area of the mask body as an essentially circumferential first shoulder, preferably as a stop for a first end face of a filter holder. Thus, when the mask is placed on the face of the mask wearer with a strap, a sealing edge of the mask in the cheek area can be supported by the first paragraph, in that the first end face of the filter holder can preferably rest against the first paragraph by pulling the strap.

The mask body 1 can be foamed in a mold. The foamed material can contain additives that have an antibacterial effect, e.g. silver ions. The mask body 1 can serve as a holder for filter elements and / or be a filter itself and / or have a filter function. The material of the mask body 1 can be porous. A three-dimensional mask body 1 can be created from a two-dimensional mask body 1 by means of certain folding techniques and cuts.

The mask body 1 can consist of one or more zones, e.g. first zone 2, flexible zone 10, or have such zones. The Shore hardness of different zones 2, 8, 10 can be different or the same. The zones 2, 8, 10 can have a different material thickness. The zones 2, 8, 10 can have different materials. It can be provided that the mask 1000 or the mask body 1 in the first zone 2 can be cut to size, for example with scissors.

The mask 1000 and / or the mask body 1 can have a former 3. The former 3 can consist of a flexible material or can have such a material. The former 3 can consist of or have a plastic, a metal or a metal alloy. The former 3 can retain its shape and serve to adapt the mask 1000 to the anatomical shape of a user. It can be provided that the former 3 is deformable by bending, so that the shape of the mask 1000 can be adapted to a face shape of a mask wearer 1001. The former 3 can also at least partially consist or have a plastic that can be cured by UV light. As an alternative or in addition, the mask 1000 or the mask body 1 can at least partially consist of or have a plastic that can be cured by UV light. If the former 3 and / or the mask 1000 and / or the mask body 1 have such a plastic, an unused mask 1000 can be stored and / or delivered in a light-tight, black cover.

The mask body 1 can have an essentially circumferential support means at least in the cheek area and in the nose area, which in the cheek area can be designed as a first shoulder as a stop for a first end face of a filter holder 6. The support means can be designed in the nose area as a second shoulder as a stop for a second end face of the filter holder 6. When the mask is on, the end faces and the shoulders can be brought into engagement by a strap 1003 in a manner that supports a sealing edge 47. The support means can be or have the former 3. It can also be provided that the support means is designed in several parts. It is also conceivable that the support means is subsequently attached and / or fastened to the mask body 1.

The mask 1000 or the mask body 1 can have an at least partially circumferential sealing edge 47. The sealing edge 47 can be arranged on and / or along the edge of the mask body 1. The mask body 1 can be stiffened by the support means in the area of the sealing edge 47. For example, the support means can be brought into engagement on the mask body 1 with the end faces of the fixed filter holder 6 with the mask 1000 on, for example essentially circumferentially, by pulling the strap 1003. The sealing edge 47 or the mask body 1 can therefore be made of a particularly flexible material, for. B. a pliable elastomer, since the sealing edge 47 can be supported by the filter holder 6 resting on the support means. By attaching a support means to the mask body 1 in a defined manner, it can also It may be possible to adapt the rigidity of the sealing edge 47 to the respective area of the mask body 1. The rigidity can be influenced, for example, by changing the distance between the support means and the sealing edge 47, or by a specific geometry of the support means in cooperation with the end face of the filter holder 6. One or more adhesive layers can expediently be present between the support means and the associated end faces of the filter holder 6, by means of which the sealing edge 47 of the mask body 1 can be additionally fixed in and / or on the filter holder 6, e.g. B. if when putting on the mask 1000 the train of the harness 1003 is not yet fully effective.

The mask 1000 and / or the mask body 1 can have a closure 4 or a connecting element 5, which are shown in detail in FIG. 4 by way of example. The closure 4 can be fluidically tight. The closure 4 can, for example, also fix the former 3, and / or, as shown in FIG. 5, serve as a flap for an outlet valve having, for example, two lips 33, 35 lying on top of one another.

One or more parts of the connecting element 5 or of the closure 4 can also serve as a shaping device for the mask body 1. The connecting element 5 can at least partially have a color code or be colored in a specific color. The color of the connecting element 5 can indicate a filter, filter type and / or filter characteristics inserted in a filter holder 6. The color code or the color coding can comply with corresponding international standards. The connecting element 5 can be or have a bolt 37. The connecting element 5 can, however, also be or have, for example, the fixed element 38 shown in FIG.

The mask 1000 and / or the mask body 1 can have at least one filter holder 6. The filter holder 6 can with the mask 1000 or the mask body 1 connected. The filter holder 6 can be formed in one piece with the mask 1000 or the mask body 1. The filter holder 6 can also be retrofitted, ie connected to the mask 1000 or the mask body 1 at a later date. The filter holder 6 can be or have a filter chamber. The filter holder 6 can be used to hold one or more, possibly different, filters. For example, one or more filter mats can be accommodated in the filter receptacle 6. The filter holder 6 can have an outer lattice structure. The outer lattice structure can be so closely meshed that the filter holder 6 can be used as a prefilter. The filter holder 6 can also be designed as a chamber with a closure. Filters and / or substances in loose form can be accommodated in the chamber, for example granules, gel balls, fibers, silica, zeolite. The filter can have at least one or more of a membrane, particle filter, UV filter, biofilter, air filter, gas filter, activated carbon filter, electrostatic filter, electrostatic filter, cyclone filter, liquid filter, oil-soaked filter, bag filter, or the like, individually or in combination.

The mask 1000 and / or the mask body 1 can have one or more filter holders 6, which can be arranged symmetrically, for example. If the mask 1000 has, for example, two mask halves or several mask parts, it can be provided that one or both mask halves or one or more of the mask parts each have a filter holder 6.

Special embodiments of the filter holder 6 can be or have a first filter holder 6 for a filter with a screw thread and / or a second filter holder 6 for a respiratory protection filter with a round thread. The first filter holder 6 and the second filter holder 6 or their embodiments can differ, for example, only in the special connection of the respective filter types. The filters can be attached directly to or in the connection opening of the filter holder 6. The support means can be designed in the cheek area of the mask body 1 as an essentially circumferential first shoulder as a stop for a first end face of the filter holder. When the mask 1000 is placed on the face of the mask wearer 1001 with the strap 1003, the sealing edge in the cheek area can be supported by the first paragraph, in that the first face of the filter holder 6 can rest against the first paragraph by pulling the strap 1003. The support means in the nose area can be embodied as an essentially circumferential second shoulder, which can be embodied in the shape of a bead, for example, and can abut directly against a second end face of the filter holder 6. In the nose region of the mask body 1, a deformation zone, for example in the form of a bellows, can additionally be attached to adapt the mask body 1 to the nose region of the mask wearer 1001.

The first shoulder can expediently be designed as an inclined, funnel-shaped surface in the transition area between the sealing edge 47 and the mask body 1. The first end face of the filter holder 6 can be designed in the area of the first shoulder to correspond to the shoulder, e.g. the inclined funnel-shaped surface.

In the chin area, the mask body 1 can have a support lip pointing towards the filter holder as a support means. The support lip can be supported against a third end face of the filter holder 6. The support lip can essentially provide support for the mask body in the chin area in the radial direction.

The filter holder 6 can be designed in such a way that it at least partially encompasses and / or covers and / or overlaps the nose area, the cheek area and the chin area of the mask body 1, cf., for example, the embodiment of the mask 1000 shown in FIG be made in one piece. The filter holder 6 can thus be an outer, stabilizing and supporting Shell for the mask body 1, which can be limp, be or have. The filter holder 6 can be designed essentially cylindrical. As a result, a particularly cost-effective positioning of the filter holder 6 as a molded part can be made possible.

The mask body 1 can be provided with an inhalation valve. The inhalation valve can be buttoned into a connection opening of the filter holder 6 and / or can be connected to it. In this way, simple assembly and disassembly of the mask body 1 can be made possible without tools. In the case of a second filter holder 6 for a respiratory protection filter with a round thread connection, the buttoned and / or connected valve housing surface of the inhalation valve can at the same time be or have a sealing surface for the round thread. In this way, a separate sealing ring can be saved, since the round thread of a filter, e.g. a respiratory protection filter, can be sealed directly with the valve housing surface of the inhalation valve. An exhalation valve can be attached in the chin area of the mask body 1, for example. Since the exhalation valve can be covered by the filter holder 6 in the assembled state, exhalation openings can be provided in the filter holder 6 below the exhalation valve. The filter holder 6 can also serve as a shock protection for the exhalation valve in this area. The exhalation valve can essentially correspond to the embodiment of the closure 4 shown in FIG. 5. The exhalation valve may, for example, have one or more of the thin sealing lips 41 shown in FIG. 5 and described further below.

The mask 1000 and / or the mask body 1 can have a fastening interface 7 for fastening a fastening tape or strap 1003. The fastening tape can be at least partially flexible and / or stretchable and / or elastic. The fastening tape can be or comprise a cord. The fastening strap can be hollow so that functional elements such as cables for headphones, transmitting or receiving units, storage media and / or Sensors passed through the fastening tape or can be received in this. The fastening tape can be a tube that can transport gaseous or liquid substances away from the mask 1000 or towards the mask 1000, for example coolants and / or liquid active substances that clean the filter and / or can be injected into the filter For example, to keep the filter moist and / or to regenerate, or to bind pollutants. The respective substances can be guided in and out of the mask 1000 or the mask body 1, in particular the filter holder 6 and / or a filter, through the fastening interface 7 and / or a further fastening interface 11. However, the fluids described below with reference to the further fastening interface 11 can also be introduced or discharged. The flow rate can provide information about the condition of the filter. It is also conceivable that disinfectants, for example guided through the hose, constantly clean the filter. The mask 1000 or the mask body 1 can have suitable liquid channels which can fluidically connect the fastening interface 7, the further fastening point 11, the filter receptacle 6 and / or further cavities in the mask 1000 or the mask body 1 to one another.

If it is provided that the filter or filters in the at least one filter holder 6 can be regenerated and / or are regenerated and / or cleaned, for example by a fluid introduced through the first fastening interface 7 or the further fastening interface 11, not all of them can be provided To regenerate or clean the filter at the same time. In this way, even when one or more filters are being regenerated or cleaned, filtering, for example of air to be inhaled through the mask carrier 1001, can be provided or ensured by means of the filter or filters that are currently not regenerating and / or cleaning.

The mask body 1 or the mask 1000 can at least partially consist of or have a solid material, for example in a reinforced zone 8 The mask 1000 and / or the mask body 1 can have a flexible zone 10 or a thin membrane 10, wherein the flexible zone 10 or the membrane 10 can be kept in shape and / or fixed in a stabilized manner by the reinforced zone 8. The filter holder 6 can be arranged in the area of the reinforced zone 8. The mask body 1 can also have a plurality of reinforced zones 8, which can be arranged, for example, symmetrically with respect to an axis of symmetry of the mask 1000. Because the mask body 1 or the mask 1000 can have at least one or more reinforced zones 8 and flexible zones 10, the mask 1000 can have high stability and / or a good and tight fit of the mask 1000 on the face of a user 1001 be ensured, while at the same time being very comfortable to wear.

The mask 1000 and / or the mask body 1 can have at least one chip, a sensor, in particular a so-called chemical nose, or a so-called electronic nose for measuring odors. For this purpose, microelectronic gas sensors can generate electronic signals. The mask 1000 can have a computer unit and / or a control unit for evaluating the measured values measured by the at least one sensor, for example. The computer unit and / or the control unit can be or have a microcontroller, an FPGA, an integrated circuit, or the like. Alternatively or additionally, it can also be provided that the mask 1000 can have a suitable interface for data transmission to an external computer unit. The suitable interface can be or have, for example, a radio interface, e.g. Bluetooth, mobile radio, loT, WiFi or the like, and / or be set up for the connection of a suitable data transmission cable. In this way, for example, the measured values and / or, if applicable, the evaluation of the computer unit can be transmitted to the external computer unit.

As described, the mask 1000 and / or the mask body 1 can have a flexible zone 10 or membrane 10. This ensures that the Mask 1000 has better tightness in areas that are deformed when speaking. The membrane 10 can, for example, be hollow and / or inflatable in order to provide an even better adaptation to the deformations of the mask 1000 or of the mask body 1 caused by speech.

The mask 1000 and / or the mask body 1 can have a further fastening interface 11 for a fastening tape or a strap 1003. The further fastening interface 11 and / or the fastening interface 7 can contain contacts, plug connections and / or coupling. There can thus be the possibility of transferring active substances or other liquid and / or gaseous substances into the filter or mask body 1 through the further fastening interface 11 and / or the fastening interface 7 via the fastening tape. The active ingredients can be or have medical active ingredients that can be transferred to a fluid flowing through the mask 1000 and / or the filter and / or to be filtered. However, the fluids described with reference to the fastening interface 7, 11 can also be introduced or carried out. The respective substances can be stored in an external container, whereby the container can be under pressure if necessary. The substances can be cleaned, detoxified and / or enriched in the external tank.

The mask 1000 and / or the mask body 1 can have at least one inflatable flea space. The inflatable flea space can be arranged, for example, on the edge and / or along the frame of the mask and / or of the mask body 1. The sealing edge 47 can be or have the inflatable flea space. Alternatively or in addition to the sealing edge 47, however, the inflatable flea space can also be provided. By suitably filling or discharging the flea space with a fluid, for example air, gas and / or liquid, the mask 1000 can be individually adapted to the shape of the face of the user 1001 when it is put on. The mask 1000 can be suitably set up for this purpose, for example have suitable valves. Assigns the mask 1000 and / or the Mass body 1 has more than one flea space, so the flea spaces can be fluidically separated from one another and / or filled separately. However, it can also be provided that some flea spaces are fluidically connected to one another. In one embodiment, the mask 1000 for filling the at least one flea space can be connected, for example, to a compressed air cylinder via a suitable connecting element.

FIG. 3 shows different embodiments of a filter or a filter holder 6 of the half-face masks according to the invention. The cross-sections shown in FIG. 3 can each correspond to either a filter or a filter layer which can be inserted into the filter holder 6. The respective cross-sections can, however, also correspond to cross-sections through the filter holder 6 with the filter inserted therein. If the cross-sections shown in FIG. 3 correspond in each case to filter layers, a filter can correspond to a combination of filter layers arranged one above the other. Even if the term filter is used below, it is obvious that a filter layer or the filter receptacle 6 with filter can also be meant without restrictions.

In a first embodiment, the filter can have at least one fleece spiral 12. Fleizspirale 12 can generate streak, e.g. up to approx. 70 °. Viruses contained in the air flowing through the filter can be inactivated by the action of the streak. At a temperature of 55 to 70 ° C (wet flitz), for example, the virus envelope can denature within a few minutes and thus a loss of infectivity.

As an alternative or in addition, the filter can have at least one biofilter 13.

The biofilter 13 can have moss or consist of moss. The biofilter 13 can, for example, have open-pore foam with possibly different pore sizes, which can have or contain nutrients for moss. The biofilter 13 can be a Have or contain cellulose acetate. The cellulose acetate can have, store or contain a liquid nutrient solution for moss. Liquid nutrient solutions are those inorganic and organic compounds from which mosses can extract the elements that make up their body. These are mostly simple inorganic compounds such as water (H20) and carbon dioxide (C02) as well as ions such as nitrate (N03-), phosphate (P043-) and potassium (K +). Provision can be made for the gases and moisture exhaled when using a biofilter 13 comprising moss to be used again in part as fertilizer for the biofilter 13. Moss consists of countless tiny leaflets, which not only form a very large surface, but can also attract positively charged microparticles such as nitrogen and carbon dioxide due to the negative charge. Particles of fine dust can serve as important nutrients for mosses. Moss is particularly good at catching fine dust and converting it into biomass via metabolism. Components of fine dust, such as salts and organic hydrocarbons, are food for bacteria, blue-green algae and unicellular organisms that vegetate on moss leaves. Liverworts can even incorporate heavy metals into their cells. Moss can also serve as protection against aggressive toxins from diesel engines and nitrogen dioxide, which can lead to inflammation in the blood vessels in the human body. One square meter of moss can absorb 13 to 22 grams of fine dust per day. If the filter has at least one heating coil 12 and one biofilter 13, then the biofilter 13 can be positioned downstream of the heating coil 12 in the direction of flow, as shown in FIG. 3.

As an alternative or in addition, the filter can have a moisture reservoir 14. The moisture reservoir 14 can generate moist fleece when the fleece spiral 12 is activated. Superabsorbents, so-called flydrogels, can be used for optimal fluid storage. These can form crosslinked polymers that are polar (e.g. polyacrylamide, polyvinylpyrrolidone, amylopectin, gelatin, cellulose). Usually, however, a copolymer of acrylic acid (propenoic acid, FI2C = CFI-COOFI) or sodium acrylate (sodium salt of acrylic acid, H2C = CH-COONa) on the one hand and acrylamide on the other hand, the ratio of the two monomers to one another can vary. If the filter has a moisture reservoir 14 and a biofilter 13, then the moisture reservoir 14 can be located downstream of the biofilter 13 in the direction of flow, as shown in FIG. 3.

Use of virucides can be provided. These substances can denature the surface proteins of a virus (e.g. formaldehyde), remove lipids from a virus envelope (alcohols, detergents) or directly damage the nucleic acids of the viral genome (alkylants).

The filter can have an airgel 15. With the mask 1000 on, the airgel 15 can shield heat from the skin surface. Aerogels are highly porous solids in which up to 99.98% of the volume can consist of pores. In this way, an air flow entering the filter or the filter chamber 6 can exit the filter or the filter chamber 6 through the airgel 15. The airgel can, for example, have a silicate base. If the filter has an airgel 15 and a moisture reservoir 14, the airgel 15 can be located downstream of the moisture reservoir 14 in the direction of flow, as shown in FIG. 3.

In a further variant of a filter 16, a disinfectant can be produced from pure salt water 20 without heating. Electrochemically treated, the solution can be given a slight voltage so that the cell nuclei of viruses or legionella can simply burst. The salt water 20 treated by electrolysis can thus destroy any type of bacteria or virus. The salt water 20 can disinfect the filters at the same time. The filter can have a water-storing, sponge-like material 21. The salt water solution can be supplied with a voltage of approx. 1-2 volts, which can be sufficient for the destruction of bacteria or viruses. Detergents and / or surfactants can also be used. Surfactants are substances that can facilitate a cleaning process. Surfactants reduce the surface tension between the surface to be cleaned, the dirt and the solvent (usually water). It is understood to mean both naturally occurring and synthetically produced surfactants (emulsifiers and wetting agents). In addition to the term detergents, the artificial word Syndet is also used in German-speaking countries for synthetic detergents.

The term “detergent” can denote a substance or a preparation which contains soaps and / or other surfactants and is intended for washing and cleaning processes. Detergents can take various forms (liquid, powder, paste, bar, slab, shaped pieces, figurines, etc.) and can be sold or used for household or institutional or industrial purposes.

The filter can have a slot 17 for inserting a test strip, test stick or the like. With test strips or test sticks an elongated object can be meant with which the presence, the amount or the concentration of a substance can be determined according to one or more criteria. The evaluation can be carried out visually or by means of electronic devices. As an aid in visual evaluation, samples are often used for color comparison, which are either applied to separate cards or directly on the packaging of the respective product.

In one or more embodiments, the filter can comprise semi-liquid gel foam 18. The semi-liquid gel foam 18 can have or contain nutrients for spores, bacteria, and / or moss. In one or more embodiments, the filter can have activated carbon 19. The activated carbon 19 can be provided, for example, to filter one or more of the following substances: chlorine, ozone and other substances that interfere with taste and smell, as well as bacteria from water, sweeteners, glycerine and chemical liquids; emitting substances and contaminants from liquid streams in the chemical or food industry; Toxins from the air (filters in respirators, ventilation systems for tanks and shelters, exhaust air in production systems); Flue gases from glass melting furnaces, waste incinerators and other waste gases; Uranium hexafluoride from the air in nuclear engineering (fuel production); Petrol vapors from exhaust air from tank systems; Chlorinated hydrocarbons from exhaust air and exhaust gases z. B. with dry cleaning; Tar from cigarette smoke in cigarette filters and / or fine dust, pollen and odors.

In one or more embodiments, the filter can have at least one channel 22 for the passage or discharge of liquid or gaseous substances.

As an alternative or in addition, the filter can have a labyrinth 23 for the air flow serving as a baffle, surfaces set up against the flow direction of the air. The surfaces can be statically charged. With ionized air it is possible to neutralize positively and negatively charged static in a very short time (<0.5 sec.). The surfaces 23 can have pores 24 and / or be porous. The pores 24 can be arranged in such a way that they do not have a preferred orientation or opening direction. As an alternative or in addition, micro-LEDs can also be built into the surfaces 24, for example LEDs that emit UV light.

In one embodiment, the filter can alternatively or additionally have one or more UV emitters 29 and / or such can be arranged in the filter chamber 6. The UV radiator 29 can be or have a UV-C LED. Of the The filter or the filter chamber 6 can optionally have a prefilter 25. The prefilter 25 can, for example, be or have a foam and / or contain fluorescent particles which, for example, can preferably emit in a range of 200-280 nm. The breathing air flowing through the filter chamber can be irradiated with the radiation emitted by the UV radiator, for example UV-C radiation, in order to kill microorganisms, in particular viruses, contained therein. A light barrier 26 can prevent UV-C radiation from penetrating to the outside can and / or can leave the filter or the filter chamber 6 to the outside. The filter and / or the filter chamber 6 can have one or more mirror surfaces 27 which can reflect radiation, in particular UV light. The radiation can thus be reflected back into the chamber in which the UVC radiator 29 can be accommodated. Due to the wall reflection of the UV-C radiation, the UV-C dose and thus the efficiency of the killing of germs can be increased significantly. Such a material that reflects UV-C radiation is, for example, polished metal, which can reflect at least 40% of the UV-C radiation. The filter and / or the filter chamber 6 can have a cooling base 28. The UV radiator 29 or the UV-C LED 29 can be cooled with a cooling system 28. In one embodiment, the cooling 28 can have at least one pelletizing element in order to cool the UV radiator 29. The UV radiator or the UV-C LED can have a large emission angle, preferably greater than 120 °, particularly preferably greater than 180 °. The UV lamp can be designed as a non-ozone-forming mercury low-pressure discharge lamp with a primary radiation of 250-280 nm. This type of emitter has the advantage over ozone-forming emitters that no ozone occurs inside or outside the filter for breathing masks.

Viruses 30 and bacteria 30 can be destroyed by the radiation. If the applied UV dose is doubled, the disinfection capacity can be increased by a factor of 10. If you double a UV dose that is needed to destroy all microorganisms 90%, you get 99% destruction of all organisms, with one Tripling it gives 99.9% destruction of the organisms and so on. The UV radiator 29 or the UV-C LED and / or the cooling system 28 can be controlled and / or regulated with a control unit 31. For this purpose, the control unit 31 is connected to at least one sensor 32 in the chamber in which the UV emitter 29 can be accommodated. The sensor 29 can, for example, measure the temperature and / or concentration and / or composition of the fluid in the chamber. The measured values measured by the sensor 29 can be transmitted to the control unit 31 and evaluated by the latter.

Air to be filtered can enter the chamber in which the UV radiator 29 is accommodated from the outside of the mask through the prefilter 25, for example, with the mask 1000 on, be filtered in the chamber by the UV radiation and exit as filtered air on the inside of the mask .

In contrast to chemical disinfection processes, UV disinfection is based on a physical process in which microorganisms can be killed quickly and effectively. When bacteria, viruses and protozoa are exposed to the germicidal wavelengths of UV radiation, they can lose their ability to reproduce and become infected. UV radiation is highly effective in inactivating a wide range of microorganisms and also eliminates chlorine-resistant pathogens such as Cryptosporidium and Giardia. UV radiation can also be suitable for breaking down toxic chemical contaminants while disinfecting them at the same time.

In one embodiment, the mask 1000 can have at least two filters and / or filter holders 6 that are fluidically separated from one another and / or spatially separated from one another. The mask wearer 1001 can thus breathe through a filter, for example, while another filter can be cleaned or regenerated. The filter can consist of a foam material or have one.

The filter can be made of open-cell foam material, PU, polyester, ceramic and / or a gel-like material that can optionally release aerosols. The filter can be porous. Cassettes filled with granulate and / or a hollow body similar to a tank with liquids are also conceivable as filters. Additives can be introduced into the filter and / or the foam, e.g. fine pores in the case of a fine dust filter, chemical substances, gases, corresponding compounds, and / or activated carbon. The filter can contain active ingredients, e.g. silver, silver ions or silver-based, zinc oxide, additives based on silver and copper, silica and / or metal powder. The active ingredients can have an antimicrobial effect. The active ingredients can also have a medicinal effect. In this way, for example, a drug can be administered when inhaling. The active ingredients can, for example, be incorporated into the filter during the manufacturing process. Provision can be made for the metal powder introduced into the filter to be heated by induction.

The filter can have pores which, for example, can be smaller than 1 micrometer, for example in cross section. The filter can be soaked in salt water. Here, for example, a current can flow or be applied. The filter can consist of transparent silicone foam, which can be externally exposed to UV-C light, for example. The external light can, for example, be generated in an external additional device and guided into the filter via glass fibers. The external additional device, for example a UV-C LED, can for example be arranged on or in the mask 1000 or the mask body 1 and / or these have the external additional device. It can also be provided that the UV-C LED is arranged in one of the filter receptacles 6, which can also be the one in which the filter is arranged. The light source can also be used to adapt the mask 1000 to the face shape of the mask wearer 1001 when it is used for the first time. The mask 1000 or the mask body 1 can at least partially consist of flexible plastic that can be cured by UV rays. The filter can have a membrane. In contrast to a sponge, a membrane filter can have a pressure-resistant structure and behave like a close-meshed, multi-layered sieve with uniform meshes, so-called pores. The filter can have a heterogeneous double membrane. The membrane filter can have a pore size of 0.2 μm, which can hold back bacteria and larger microorganisms on the surface. A breakthrough of already separated microorganisms can therefore be impossible, even with high pressure fluctuations or pressure surges. The pore size can also be between 0.01 and 8 μm. For example, a pore size of 0.2 μm can be suitable for sterile filtration, 0.45 μm for determining the number of colonies and for particle removal, and 0.65 μm for determining or removing flecks and molds.

The membrane filter can consist or have of high-purity cellulose derivatives, of polytetrafluoroethylene, of polyamide and / or of gelatin.

FIG. 4 shows an embodiment of the closure 4. A first closure lip 33 can form the closure 4 with a corresponding second closure lip 35. The first sealing lip 33 can have openings 34 through which the corresponding locking elements 36 of the second sealing lip 35 can be guided. The locking elements 36 can be U-shaped. If the locking lips 33, 35 or sealing lips lie sealingly on top of one another, as shown in FIG. 4, the locking elements 36 can protrude over the first sealing lip 33 so that a latch 37 is parallel to the plane of the first sealing lip 33 or the contact surface of the sealing lips 33, 35 can be pushed through the locking elements 36. Loosening of the sealing lips 33 and 35 by the bolt 37 can thus be prevented.
