Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings of the present invention, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The first embodiment is as follows:

according to fig. 1, an anti-pressure sore face mask mainly comprises: the mask body 1 is covered at the mouth and nose part of a user, and a trachea interface 2 extending outwards is arranged in the middle of the mask body 1 and is used for being communicated with breathing equipment; the driving impeller 3 is arranged in the air pipe connector 2, the driving impeller 3 is provided with an output shaft 4, and the output shaft 4 extends to the outside of the air pipe connector 2 through a shaft hole; the impeller pump 5 is fixedly arranged on the outer side wall of the air pipe connector 2, and an input shaft of the impeller pump 5 is coaxially connected with the output shaft 4; a first annular duct 6, arranged around the edge of the opening of the mask body 1, said first annular duct 6 being in contact with the skin of the user for sealing the edge of the mask body 1; a plurality of vent holes 7 are densely distributed in the area of the first annular pipeline 6 corresponding to the skin of the human face; a first air inlet interface 8 communicated with the interior of the first annular pipeline 6 is arranged in a region, which is not overlapped with the vent hole 7, of any one side of the first annular pipeline 6, and the first air inlet interface 8 is communicated with an air outlet end 9 of the impeller pump 5 through a hose; and the exhaust valve 10 is arranged in the area, which is not overlapped with the trachea interface 2, in the center of the cover body 1, and is used for exhausting the gas exhaled by the user.

Through the arrangement, when a user wears the pressure sore prevention mask to breathe, the air sucked from the air pipe connector 2 blows to drive the impeller 3 to rotate, the impeller 3 is driven to drive the external impeller pump 5 to work through the output shaft 4, the air flow blown out by the impeller pump 5 is guided into the first annular pipeline 6 through the hose and is discharged from the vent hole 7, an air film is formed between the skin of the face of the user and the first annular pipeline 6, and pressure sores caused by long-term skin compression are avoided. Wherein, the cover body 1 is fixed with the face of a user through a fixing band, so that the cover body 1 cannot be moved away and dislocated at four positions due to the generation of an air film; in addition, the working mode of the driving impeller 3 is ensured, the cover body 1 is provided with the exhaust valve 10 independently, the air inlet part and the air outlet part of the cover body 1 are separated, and the stress direction of the driving impeller 3 is ensured to be invariable all the time, so that a guarantee condition is provided for the formation of an air film.

Example two:

the exhaust fan cover further comprises a second annular pipeline 11 which surrounds the opening edge of the cover body 1 and is parallel to the first annular pipeline 6, the second annular pipeline 11 is arranged flexibly, a second air inlet port 12 which is communicated with the inside is formed in the second annular pipeline 11, and the second air inlet port 12 is communicated with the exhaust end 9 of the impeller pump 5 through a hose.

Through the above arrangement, in the process of breathing by a user, the air flow fluctuation in the air pipe interface 2 enables the air pressure at the exhaust end 9 of the impeller pump 5 to change, the flexible second annular pipeline 11 is enabled to expand and contract continuously through the air pressure change, when the second annular pipeline 11 expands, the cover body 1 is used as a sealing support for the user, the pressure of the first annular pipeline 6 on the face of the user is reduced, when the second annular pipeline 11 contracts, the pressure of the cover body 1 is borne by the first annular pipeline 6 again, therefore, the alternative change of the support part is brought to the user, the discomfort caused by long-time compression of the same position is avoided, and meanwhile, the effect of extrusion massage is achieved.

Example three:

according to fig. 2 and 3, the device further comprises a third annular pipeline 13 which is arranged in parallel with the second annular pipeline 11 around the opening edge of the cover body 1, the third annular pipeline 13 is flexibly arranged, the third annular pipeline 13 is provided with a third air inlet port 14 communicated with the inside, and the third air inlet port 14 is communicated with a suction end 19 of the impeller pump 5 through a hose; the air pipe connector further comprises a coil spring 15 nested on the output shaft 4, wherein the inner end of the coil spring 15 is connected with the outer side wall of the output shaft 4, and the outer end of the coil spring 15 is connected with the inner side wall of the air pipe connector 2.

Through the arrangement, in the process of inhaling air by a user, the air flow in the air pipe connector 2 drives the impeller 3 to rotate, the output shaft 4 drives the impeller 3 to pump air into the second annular pipeline 11, so that the second annular pipeline 11 expands to bear the supporting and sealing functions of the cover body 1, and meanwhile, the rotating output shaft 4 drives the coil spring 15 to tighten, so that the coil spring 15 gathers elastic potential energy. When a user exhales, the air pipe connector 2 does not admit air, no air flow enables the driving impeller 3 to rotate, at the moment, under the releasing action of the coil spring 15, the output shaft 4 rotates at a high speed, the driving impeller 3 pumps reversely, at the moment, the impeller pump 5 pumps out air in the second annular pipeline 11 through exhaust short time and conveys the air into the third annular pipeline 13 through air suction short time, the third annular pipeline 13 expands to bear the supporting and sealing functions of the cover body 1, and the operation is repeated in a cycle, under the alternative work of the second annular pipeline 11 and the third annular pipeline 13, long-time compression of the cover body 1 on the same position of the face of the user is avoided, pressure sores are avoided, and meanwhile, the heat dissipation massage effect is also achieved.

Example four:

the outer side walls of the contact parts of the second annular pipeline 11 and the third annular pipeline 13 with the face of the user are attached with moisture-proof layers 16.

The uncomfortable sense that causes when the effectual second toroidal tube 11 of avoiding of dampproof course 16 among the above-mentioned setting, third toroidal tube 13 and user's skin contact wherein this dampproof course 16 preferred uses the cotton-flax cloth material, still has the sweat-absorbing effect when improving the comfort level.

Example five:

according to fig. 3, the outer arm of the output shaft 4 is provided with a weight 17 in the circumferential direction.

The counterweight 17 in the above arrangement is started to store energy, so that the impeller 3 is driven to rotate no matter a user exhales or inhales, and a continuous working state of the impeller pump 5 is ensured, so that the ventilation holes 7 of the first annular pipeline 6 are always blown by breeze to achieve a ventilation state.

Example six:

according to fig. 4, the exhaust valve 10 communicates with the first inlet port 8 via a bellows; the bellows is provided with a water-blocking isolator 18.

In the above-mentioned setting, through the bellows with the leading-in first ring channel 6 of the gaseous of user expiration, and discharge through air vent 7, form short-lived air film between first ring channel 6 and user's facial skin, avoid pressing the production of sore, in avoiding the moisture of expired gas to get into first ring channel 6 simultaneously, isolator 18 that blocks water on the bellows, effectual moisture to in the air current filters, thereby the drying environment in first ring channel 6 has been kept, avoid causing the discomfort to the user.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
