A portable breathing apparatus has a respirator and a filter. The filter has a multifunctional strainer, a photocatalyst element, an exhauster, a high-pressure generator and an active carbon net in the interior thereof. Via the exhauster, external air can be filtered by the multifunctional strainer and mixed with ozone and negative ions generated from the photocatalyst element and the high-pressure generator thereby filtering and sterilizing the external air. Furthermore, the external air passes through a tube via the active carbon net to the respirator. Hence, it is easy for people wearing the portable breathing apparatus to breathe and experience the functions of air sterilization and filtration.

Disclosed are: a non-woven fabric for a multi-functional filter, which has excellent adsorption performance on various toxic / hazardous substances such as malodorous substances, VOCs, allergens and pathogenic viruses, has an anti-bacterial / anti-fungal activity, and rarely undergoes pressure loss; and a method for producing the non-woven fabric in a simple manner. Specifically disclosed are: a non-woven fabric for a filter, which comprises an insolubilized metal-crosslinked polypeptide and a non-woven fabric coated with the polypeptide and has excellent adsorption performance, and which can be produced by such a simple process that the non-woven fabric is immersed in an aqueous polypeptide solution and further treated with a metal salt; and a process for producing the filter in a simple manner.

Filters, more particularly to multifunctional filters that are capable of removing as well as adding components to a filtered material are provided by the present invention. In addition to a multifunctional filter, the present invention relates to the use of such a multifunctional filter in an apparatus, to process a filtrate and to the filtrate produced by the process of the present invention.

An integrated filter assembly is provided. The filter assembly includes a fastener that holds two substantially opposing elements of a housing together. Also included is a multi-purpose filter that has at least a particle filter component and a chemical filter component. The multi-purpose filter is attached to the fastener. The multi-purpose filter is within the housing when the fastener holds the two substantially opposing elements of the housing together.

The invention relates to a gas generator (10) for use in a safety device for motor vehicles comprising a housing and a propellant (4) contained in a combustion chamber (25) of the housing for generating a pressurized gas, the housing comprising a first housing part (40) and a second housing part (30) at least partly surrounded by the first housing part (40) and at least one igniter (6) for igniting the propellant (4), and an annular filter (50) surrounding the combustion chamber (25) in which the propellant (4) is located. The filter (50) comprises a peripheral portion (52) and a radial portion (51), the radial portion (51) serving as filling body for the propellant (4) in the combustion chamber (25).

The invention discloses a multifunctional filter which comprises a cylindrical filter body, wherein a feed port and a filtrate outlet are formed at the upper and lower ends of the filter body. The multifunctional filter is characterized in that two rotary shafts are symmetrically arranged on the two sides of the filter body respectively; the rotary shafts are sleeved on a shaft sleeve; the shaft sleeve is arranged at the top of the base; a positioning disc is also fixed on each rotary shaft; corresponding positioning pin holes are circumferentially formed in the positioning disc and the shaft sleeve; and a positioning pin passes through the positioning pin holes at the same time to fix the positioning disc and the shaft sleeve. The filter disclosed by the invention is arranged on a base through the rotary shafts, a certain angle can be selected as necessary, and then a positioning pin is inserted for positioning and fixing, therefore, the filter is convenient to disassemble and clean, and later maintenance is easier.

An air purifier, characterized in that it includes a suction grill that guides air inhaled from the rear, a multifunctional filter assembly that purifies air passing through the suction grill, a bottom surface discharge port that guides the purified air to discharge to the bottom surface, and guides the purified air to discharge to the bottom surface. The air is discharged to the side through the side exhaust port. The invention can improve the air purification efficiency and bring people a more comfortable environment.

The invention relates to the field of environmental protection, in particular to a multi-functional, full-structure, high-efficiency, cleanable ultra-static air purification system. It is a multifunctional filter that removes particles, removes TOVC, sterilizes and removes odors, and can release negative ions. The filter is composed of a primary filter plate (1), an ionization plate (2), a dust collecting plate (3), an ultraviolet lamp (4) and a high-voltage negative ion power supply (5). Mainly through the combination of negative ion technology and high-voltage power supply, the use of electrostatic adsorption technology, the addition of nano-materials that can sterilize and deodorize, remove formaldehyde, benzene and other harmful gases, use the principle of photocatalysis, use high-tech nano and nano-modification technology, and pass multiple screenings , composition and activation modification, multi-layer waterproof insulation sealing structure, to achieve a multi-functional combined washable nano-filter that can release negative ions, remove particulate matter, remove formaldehyde and other harmful gases, sterilize and deodorize, so as to achieve the goal of purifying the air Effect. This product can be cleaned and used repeatedly, which reduces the cost of use and improves the service life.
