Description

Breathing filter structure

The present invention relates to a respiratory filtering structure, in particular to a breathing filter structure having an exhaust pipe, which has the advantages and effects of separate discharge of the exhaust gas and smooth exhalation process.

As shown in the ninth, tenth, and tenthth drawings, it is a conventional technical diagram in which a one-way exhaust valve 91 is provided on a general mask 90.

The mask 90 and the face of a user 70 have a certain mask space 95. When the user 70 inhales, the gas 71 cannot pass through the one-way exhaust valve 91, and can only be filtered through the mask 90. When the user 70 exhales and the air pressure reaches a predetermined value, the airtight valve body 911 of the one-way exhaust valve 91 is opened, and the gas 71 is discharged out of the mask 90.

However, in such a design, when the user 70 exhales, the discharged exhaust gas body (e.g., carbon dioxide) is easily dispersed in the mask space 95, not only mixed with the gas filtered through the mask 90, but also the pressure is easily dispersed in the mask space. In 95, it is difficult to completely push open the one-way exhaust valve 91, which is liable to cause a phenomenon of unsatisfactory exhalation.

Therefore, it is necessary to develop new products to solve the above shortcomings and problems.

The purpose of the present invention is to provide a respiratory filtering structure, which has the advantages and effects of separate discharge of the exhaust gas and smooth exhalation process, and is used to solve the problems of easy mixing and unsmoothing of the exhaust gas of the prior art.

The technical means for solving the above problems is to provide a respiratory filtering structure, comprising: a filtering body having an outer surface and an inner surface, the inner surface facing a user and forming a predetermined with the user Space, and the filter system is a filter material and has gas permeability; a unidirectional exhaust portion is disposed on the filter body for restricting one-way circulation of gas; an exhaust pipe having two ends, one end of which is connected to the one-way exhaust portion, and the other end And extending to the user's mouth for the user to exhale; and the one-way exhausting portion is only for the gas flowing from the exhaust pipe to the one-way exhausting portion to pass outward Discharging; thereby, when the user inhales, the gas system outside the outer surface enters the inner surface direction space through the filtering of the filter body, and when the user exhales, the discharged gas is discharged by the exhaust The tube is discharged outward through the one-way exhaust portion.

The above objects and advantages of the present invention will be readily understood from the following detailed description of the embodiments and the accompanying drawings.

Figure 10B is a schematic diagram of the exhaust of a mask with a one-way exhaust valve.

As shown in the first to fourth figures, the present invention is a respiratory filtering structure comprising: a filter body 10, a unidirectional exhaust portion 20 and an exhaust pipe 30.

The filter body 10 has an outer surface 11 and an inner surface 12 facing the user 70 and forming a predetermined space 13 with the user 70, and the filter body 10 is a Filter material and breathable.

The unidirectional exhaust portion 20 is disposed on the filter body 10 for restricting unidirectional circulation of gas.

The exhaust pipe 30 has two ends, one end of which is connected to the one-way exhausting portion 20, and the other end is extended to the predetermined space 13 to the mouth of the user 70 for the user 70 to exhale (for example: It fits around the mouth of the user or in the mouth of the user 70).

Further, the one-way exhaust unit 20 is discharged only by the passage of the gas flowing through the exhaust pipe 30 to the one-way exhaust unit 20.

Thereby, when the user 70 inhales, the gas system outside the outer surface 12 enters the predetermined space 13 through the filtering of the filter body 10, and when the user 70 exhales, the discharged gas will be discharged from the row. The air tube 30 is discharged outward through the one-way exhaust portion 20.

In practice, the one-way exhaust unit 20 can adopt a one-way exhaust valve generally on the market; as shown in the third, fourth and fifth figures, the one-way exhaust unit 20 has a frame body 21 and An airtight valve body 22, the frame body 21 has a plurality of venting portions 23, the airtight valve body 22 is attached to the frame body 21, and is an airtight material; as shown in the third figure, When the gas 71 flows from the outside to the unidirectional exhaust portion 20, the gas-impermeable valve body 22 is attached to the frame body 21, so that the gas 71 cannot pass, and the filter portion 10 can only enter the predetermined space. 13; as shown in the fourth figure, when the user 70 exhales, the gas 71 will blow the gas-tight valve body 22, and the gas-impermeable valve body 22 is blown away from the frame 21, thereby The venting portion 23 flows to the outside. Of course, spit it out The pressure of the gas 71 is required to push the gas impermeable valve body 22 to be discharged outward through the venting portion 23.

In more detail, regarding the breathing filter structure of the present invention, it can be directly made into a general mask (refer to the first to fourth figures), and can also be applied to general protective clothing such as dustproof clothing and sandproof clothing. (See sixth and seventh figures).

Of course, a mask with a one-way exhaust valve is generally provided. When the user 70 exhales, the discharged exhaust gas body (such as carbon dioxide) is easily dispersed in the mask space, which not only mixes with the gas filtered by the mask, but also has easy pressure. Dispersed in the mask space, it is difficult to completely push open the one-way exhaust valve, which is easy to cause the phenomenon of unsatisfactory exhalation. When the one-way exhaust valve is disposed in the protective filter clothing, especially the multi-type protective clothing, the space is large, and after the user 70 exhales, the gas pressure is more likely to be dispersed due to dispersion, thereby causing unsatisfactory exhalation. The present invention utilizes the exhaust pipe 30 to directly exhale, and not only the discharged exhaust gas body is separated from the filtered gas in the predetermined space 13 but also the exhaust gas is concentrated in the exhaust pipe 30. The air pressure is increased, and the airtight valve body 22 can be smoothly pushed open, whether applied to a mask or a protective filter, so that the user 70 can smoothly exhale.

In addition, regarding the design of the exhaust pipe 30, it can be a generally equal diameter round pipe (such as FIG. 8A) and a tapered cone pipe (such as the eighth B diagram, which is tapered by a first diameter D1. Up to a second diameter D2), an elastic telescopic tube (such as the eighth C diagram), and then the tube is placed around the mouth of the user 70 or placed in the mouth according to different needs (contracted to slightly It can be placed in the mouth smaller than the mouth; of course, the design of the adjustable length of the flexible telescopic tube can adjust the exhaust pipe 30 to the most suitable length according to the needs of use.

Further, as shown in FIGS. 8D and 8E, the exhaust pipe 30 is provided for the user 70 to exhale one end, and may also be designed in the shape of a general bell mouth.

In summary, the advantages and effects of this creation can be summarized as:

[1] The exhaust gas is discharged separately. Generally, a mask with a one-way exhaust valve is provided. When the user 70 exhales, the discharged exhaust gas body (such as carbon dioxide) is easily dispersed in the mask space and mixed with the gas filtered by the mask; and the creation utilizes the row. The gas pipe 30 directly exhales, and the discharged exhaust gas body can be separately discharged, and is separated from the filtered gas in the predetermined space 13.

[2] The exhalation process is smooth. Generally, a mask with a one-way exhaust valve is used. When the person 70 exhales, the gas pressure of the discharge gas is easily dispersed in the mask space, and it is difficult to completely push open the one-way exhaust valve, which may cause the phenomenon of unsatisfactory exhalation; and the present invention uses the exhaust pipe 30 to directly exhale, so that the spit can be discharged. The gas pressure is concentrated to smoothly push the gas-tight valve body 22 of the one-way exhaust portion 20, so that the user 70 can smoothly exhale.

The above is only a detailed description of the present invention by way of a preferred embodiment, and any modifications and variations of the embodiments are possible without departing from the spirit and scope of the present invention.

From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the aforementioned objectives, and has been in compliance with the provisions of the Patent Law, and proposes a new type of patent application.
