Definitions

  • 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 a mask and filter in one.
  • 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 and have a relatively large filter surface and are relatively hygienic. It is disadvantageous that conventional half masks are overall somewhat 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 .
  • 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 Ci.
  • 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.
  • 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.
  • 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 degree of rigidity of the mask body or the sealing edge when wearing the half mask is perceived as uncomfortable.
  • 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.
  • 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.
  • standardized masks with CE marking can protect against respirable dusts and liquid mists within their respective area of application.
  • they can have layers, for example with a meltblown Vhes, with an electrostatic material. Small dust particles and drops of liquid can be bound in the filter by electrostatic forces.
  • the electrostatic effect is quickly lost through exhaled moist air and dust accumulation. Tests have shown that the static charge is lost after just two hours of wear, among other things due to moisture that collects in the mask fabric. Even if the mask is dried, for example in an oven, the mask function can no longer be established. It is therefore an object of the invention to provide a mask which overcomes these disadvantages and whose electrostatic filtering effect lasts longer.
  • the filter effect of the mask according to the invention can be improved.
  • the present invention is characterized in that the at least one filter has at least one or more of activated carbon, UV filter and / or UV radiator, filter fleece, electrical and / or electrostatic filter, membrane filter and / or particle filter. It can be provided, for example, that the filter has an electrical and / or electrostatic filter.
  • the filter can have a filter fleece, for example. Combinations of activated carbon, UV filter and / or UV radiator, filter fleece, electrical and / or electrostatic filter, membrane filter and / or particle filter can also be possible.
  • the filter fleece can be a nonwoven fabric.
  • the filter fleece can be set up to filter pollutants and / or viruses from a fluid.
  • the mask can have at least one filter holder, wherein at least one filter can be received in the filter holder, wherein the filter holder can be arranged preferably and / or essentially at least in the mouth area and / or in the nose area of a mask wearer when the mask is in place.
  • the filter can be releasably connected to the mask and / or the mask body, preferably to the filter holder. This means that a filter can be changed quickly, for example if the filter effect is too low due to use or to regenerate the filter.
  • the filter and / or the electrical filter and / or electrostatic filter can have a grid.
  • the grid can preferably have a metal, particularly preferably copper, brass, silver, gold and / or combinations thereof.
  • the mesh can also have corresponding alloys, for example an alloy comprising copper, brass, silver and / or gold.
  • the grid may or may not be powered.
  • the grid can be or become electrostatically charged.
  • the grid can be or be electrostatically charged by a power supply.
  • the grid can be arranged between a first layer and a second layer, wherein the first and / or the second layer can comprise a fleece.
  • the grid can be sandwiched between the two layers.
  • the two layers can support and / or fix the grid.
  • the fleece can be a filter fleece or the filter fleece.
  • the fleece can have a filter effect.
  • the first and / or the second layer can be or have a meltblown fleece.
  • the meltblown fleece can preferably comprise a plastic, particularly preferably polypropylene.
  • the filter fleece can be or have a meltblown fleece.
  • the filter can have a molecular sieve.
  • the molecular sieve can have zeolites or activated carbon.
  • the molecular sieve can be arranged in front of or behind the grid in the direction of flow through the filter.
  • the molecular sieve can be supported, held or enclosed by the first, second or a further layer.
  • One or the UV radiator can be arranged in the filter in such a way that one or the filter fleece can be irradiated by the UV radiator.
  • pollutants or viruses that are present or filtered on or in the filter fleece can be deactivated or decomposed by the irradiation by the UV light.
  • the filter fleece can be or become disinfected by exposure to the UV lamp. The reusability of the mask can thus be increased.
  • the filter fleece can have a fluorescent substance with which the filter fleece is impregnated.
  • the fluorescent substance can be designed to be activated by the UV emitter.
  • the emitted wavelength of the fluorescent substance can be 250-400 nm, which has been found to be harmful to many viruses.
  • the mask and / or the filter can have an energy store, preferably a replaceable battery, and a control unit.
  • the energy store can be connected to the electrical filter and / or electrostatic filter and / or the grid for the power supply, wherein the control unit can be set up to control or regulate the power supply.
  • the control unit can activate or deactivate a power supply for the grid, for example.
  • the energy store can be connected to the UV radiator for power supply, wherein the control unit can be set up to control or operate the UV radiator.
  • the mask and / or the filter can have a solar cell which can be connected to the energy store and / or the control unit. The energy store can be charged by the solar cell.
  • the mask and / or the filter can have a flow sensor which can be configured to detect fluid to be filtered flowing in through the mask and / or the filter and / or fluid flowing out of the mask and / or the filter.
  • the flow sensor can be connected to one or the control unit, so that upon detection of fluid flowing through the mask and / or filter, preferably fluid flowing in and / or out, the control unit controls the power supply to the grid and / or the electrical filter can be. Alternatively or additionally, upon detection of fluids flowing through the mask and / or filter, preferably fluids flowing in and / or out, the control unit can control the UV radiator so that the filter fleece is or can be irradiated by the UV radiator.
  • the flow sensor can have a swivel plate and a contact, which can be swiveled about an axis of rotation into a flow position when the flow is flowing through the filter, so that the swivel plate can contact the contact in the flow position. If the contact is contacted by the swivel plate, it can be provided that the flow sensor transmits a signal to the control unit that indicates a flow.
  • the flow through can be or have a flow of a fluid into the filter or the mask. It can be provided that the flow sensor has a second contact which is arranged in such a way that it is contacted by the swivel panel when there is a flow through the filter in the opposite direction (e.g. an outflow). The flow sensor can thus detect different flow directions in a simple manner and communicate with the control unit.
  • the mask and / or the mask body can have a superabsorber at least in sections.
  • the superabsorber can preferably form at least part of the mask body.
  • the superabsorbent can be designed to absorb liquid.
  • the superabsorber can be arranged in such a way, preferably on or in an inside of the mask, that when the mask is on, moisture located inside the mask can be or can be absorbed by the superabsorbent.
  • the superabsorber can be arranged, for example, at those points on the inside of the mask at which condensate collects and / or exhaled air preferably condenses when the mask is on.
  • the superabsorber can be arranged, for example, in an area which, when the mask is put on, can be on, at or near an area of the mouth or nose.
  • the mask can have an oxygen generator, wherein the oxygen generator can be fluidically connected to an oxygen admixing unit which can be configured to enrich fluid flowing through the mask with oxygen. It can be provided that the mask has several oxygen generators in order to be able to provide oxygen continuously, for example. If the oxygen generators have to be regenerated, the multiple oxygen generators can be controlled or operated cyclically in such a way that when at least one oxygen generator is regenerated, at least one of the other oxygen generators does not regenerate or provides oxygen. If, for example, one of the oxygen generators is being regenerated, the remaining oxygen generator (s) can provide oxygen.

If a fluid flows through the flow sensor 150, compare, for example, streamline 132, then the swivel plate 136 can be or can be swiveled about the axis of rotation 137. In a rest position, in which there is no flow through the flow sensor 150, it can be provided that the pivot plate 136 makes contact with the contacting point 131.
  • the swivel plate can, for example, have a contactor 134, which can contact the contact point 131, for example, in the rest position. If the contacting point 131 is contacted, the flow sensor 150 can communicate a non-flow to the control unit 111. For example, a corresponding no-flow signal, for example a voltage or the like, can be transmitted or applied to the control unit 111 via the closed contact point 131. If the flow is flowing through the flow sensor 150, the swivel plate can be or be swiveled into a flow position in which the contact point 131 is no longer or will no longer be contacted. In this case, the flow sensor 150 can communicate a flow to the control unit 111.
