Description

Breathing filter

Technical Field

The utility model relates to the technical field of medical equipment, specifically a respiratory filter.

Background

The respiratory filter is a filter used in a respiratory circuit, has the functions of biological filtration heating in different degrees and reducing the generation of clean raw water, prevents the collapse of small airways and atelectasis, and can reduce the microbial pollution of the respiratory circuit and reduce the nosocomial pollution. The respiratory filter generally comprises a front cover and a rear cover, wherein an electrostatic filter membrane is clamped between the front cover and the rear cover and is used for isolating germs; in the conventional respiratory filter, germs are concentrated at the middle position of the filtering membrane, the utilization rate is not high, and the adsorptivity is poor.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the technical problem that the utilization rate of an electrostatic filtering membrane in a traditional breathing filter is not high is solved.

The utility model provides a respiratory filter, protecgulum and hou gai including interconnect, the protecgulum with be provided with electrostatic filtration membrane between the back lid, the protecgulum is equipped with a plurality of first guide vanes that are the vortex and evenly arrange, the back lid is equipped with a plurality of second guide vanes that are the vortex and evenly arrange, the protecgulum with when the back lid is connected, first guide vane with second guide vane vortex direction is the same.

The first air guide sheet and the second air guide sheet guide air blown into the filter, so that part of air concentrated at the center of the electrostatic filter membrane is diffused to the periphery of the electrostatic filter membrane, the whole electrostatic filter membrane has a filtering effect, and the problem that the utilization rate of the electrostatic filter membrane in the traditional breathing filter is not high is solved.

Furthermore, a first reinforcing column is connected to the position, close to the center of the front cover, of the first air deflector, and the diameter of the first reinforcing column is larger than the thickness of the first air deflector; and a second reinforcing column is connected to the second air guide sheet at a position close to the center of the rear cover, and the diameter of the second reinforcing column is larger than the thickness of the second air guide sheet. Because the air blown in by the filter is concentrated at the circle center positions of the front cover and the rear cover, the stress is large, the strength of the air guide sheet is increased through the reinforcing column, and the air guide sheet is not easy to deform.

Furthermore, a clamping groove is formed in the peripheral wall of the rear cover, and clamping teeth clamped with the clamping groove are arranged on the front cover. The clamping groove is clamped with the clamping teeth, so that the front cover, the rear cover and the rear cover are installed, and the operation is simple and convenient.

Further, the latch head is equipped with the barb, the draw-in groove bottom be equipped with the bayonet socket of barb joint. Through barb and bayonet joint, make protecgulum and back lid difficult break away from.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1, the present invention relates to a respiratory filter, which comprises a front cover 1 and a rear cover 2 connected with each other, wherein an electrostatic filtering membrane is arranged between the front cover 1 and the rear cover 2, as shown in fig. 4 and 5, the front cover 1 is provided with six first air deflectors 11 uniformly arranged in a vortex manner, as shown in fig. 6 and 7, the rear cover 2 is provided with six second air deflectors 21 uniformly arranged in a vortex manner, and when the front cover 1 is connected with the rear cover 2, the vortex directions of the first air deflectors 11 and the second air deflectors 21 are the same; a first reinforcing column 12 is connected to the position, close to the circle center of the front cover 1, of the first air deflector 11, and the diameter of the first reinforcing column 12 is larger than the thickness of the first air deflector 11; the second air deflector 21 is connected with a second reinforcing column 22 close to the circle center of the rear cover 2, the diameter of the second reinforcing column 22 is larger than the thickness of the second air deflector 21, and because the air blown by the filter is concentrated at the circle center positions of the front cover 1 and the rear cover 2, the stress is larger, the strength of the air deflector is increased through the reinforcing column, and the air deflector is not easy to deform;

as shown in fig. 3, a clamping groove 23 is formed in the peripheral wall of the rear cover 2, a bayonet 24 is formed at the bottom of the clamping groove 23, as shown in fig. 2, a latch 13 clamped with the clamping groove 23 is formed in the front cover 1, and an agnail 14 clamped with the bayonet 24 is formed at the head of the latch 13; the front cover 1 and the rear cover 2 are installed by clamping the clamping groove 23 and the clamping teeth 13, and the front cover 1 and the rear cover 2 are not easy to separate by clamping the barbs 14 and the bayonets 24;

the first air guide plate 11 and the second air guide plate 21 guide air blown into the filter, so that part of the air concentrated at the center of the electrostatic filter membrane is diffused to the periphery of the electrostatic filter membrane, the whole electrostatic filter membrane has a filtering effect, and the problem that the utilization rate of the electrostatic filter membrane in the traditional breathing filter is not high is solved.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
