Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-2, a compressed oxygen self-rescuer with high safety performance comprises a self-rescuer body 1, an oxygen storage cavity 2 is formed in the side wall of the self-rescuer body 1, an air bag 14 is fixedly connected to the upper end of the self-rescuer body 1, and a breathing mask 15 communicated with the interior of the air bag 14 is installed at the upper end of the air bag 14.

Square groove 3 has been seted up to the lower extreme of self-rescuer body 1, and square groove 3's interior top fixedly connected with is by the tee bend pipe 5 of violently managing 51 and standpipe 52 constitution, and the intercommunication has intake pipe 4 between violently managing 51 and the oxygen storage chamber 2, and the intercommunication has outlet duct 7 between violently managing 51 and the gasbag 14, and square groove 3's embedded blast pipe 9 that is equipped with is installed to the carminative exhaust apparatus in the directional blast pipe 9 in the standpipe 52.

The aqua storage tank 8 has been seted up to self-rescuer body 1's lateral wall, and in blast pipe 9 extended to aqua storage tank 8, the embedded strip 12 that absorbs water that is equipped with of blast pipe 9, the strip 12 that absorbs water sealed the pipe wall that runs through blast pipe 9 and extended to aqua storage tank 8 in, the first spring 13 of the upper end fixedly connected with of strip 12 that absorbs water, and the surperficial fixedly connected with of first spring 13 and the continuous fine hair that absorbs water of strip 12 that absorbs water.

It should be noted that, the absorbent velvet and the absorbent strip 12 both use high molecular water-absorbent resin, and the hydrophilic groups carried by the structure of the absorbent velvet and the absorbent strip endow the absorbent velvet and the absorbent strip with extremely strong water absorption, so as to ensure that water on the absorbent velvet can be supplemented in time after being shaken off.

The exhaust device comprises a sliding plug 6 which is connected in the vertical pipe 52 in a sealing and sliding manner, the sliding plug 6 is made of a magnetic material, an electromagnetic pulse valve 41 is installed in the air inlet pipe 4, and the installation means of the electromagnetic pulse valve 41 is the existing mature technology and is not described in detail.

And the upper surface of the sliding plug 6 is streamline, and the upper end of the sliding plug 6 is elastically connected to the inner wall of the transverse pipe 51 through the second spring 16.

It is worth mentioning that by streamlining the upper surface of the spool 6, the flow rate of oxygen above the spool 6 can be made faster, thereby further increasing the pressure difference between the upper and lower sides of the spool 6 to ensure that it can move upward against the elastic force of the second spring 16.

The first spring 13 is made of an iron material, the second spring 16 is made of a non-magnetic conductive material, the standpipe 52 is provided with a first check valve 11, and the exhaust pipe 9 is provided with a second check valve 10.

It should be noted that the first check valve 11 only allows air to flow into the standpipe 52 and not out, and the second check valve 10 only allows air to flow from the standpipe 52 into the vent pipe 9. And a first check valve 11 is provided at the air inlet end of the standpipe 52 and a second check valve 10 is provided at the air inlet end of the exhaust pipe 9.

When a fire disaster happens, the self-rescuer body 1 is worn on the body, the air outlet end of the exhaust pipe 9 is aligned with the body, and the electromagnetic pulse valve 41 is opened after the respirator 15 is worn. When the electromagnetic pulse valve 41 is opened, the oxygen compressed in the oxygen storage cavity 2 is discharged into the air inlet pipe 4 in a pulse form, and flows into the air bag 14 through the three-way pipe 5 and the air outlet pipe 7 to be breathed by the escape personnel.

Whenever the compressed oxygen flows in the horizontal pipe 51 in the three-way pipe 5 at a high speed, the gas above the sliding plug 6 has a high flow rate and a low pressure, and the air below the sliding plug 6 hardly flows and has a high pressure, so that a pressure difference is generated between the upper side and the lower side of the sliding plug 6, and the sliding plug 6 moves upwards for a certain distance and finally keeps balance under the elastic force of the second spring 16. When the air inlet pipe 4 stops supplying air into the three-way pipe 5, the air flow rate of the upper side and the lower side of the sliding plug 6 is the same, the pressure difference disappears, the second spring 16 extends and recovers, and the sliding plug 6 moves downwards and restores. This allows the sliding plug 6 to reciprocate up and down within the standpipe 52 during the pulsed exhaust of the inlet line 4. When the electromagnetic pulse valve is used, the pulse frequency of the electromagnetic pulse valve 41 can be adjusted to a higher state, so that the normal breathing of the escape personnel is not influenced, and the sliding plug 6 can move up and down in the vertical pipe 52 at a high frequency.

Under the flow limiting effect of the first check valve 11 and the second check valve 10, the sliding plug 6 moving up and down at high frequency can suck air containing smoke below the self-rescuer body 1 into the vertical pipe 52 and then discharge the air from the exhaust pipe 9. Meanwhile, the magnetic sliding plug 6 is continuously close to and far from the first spring 13 in the process of moving up and down, and the first spring 13 is continuously extended and contracted, and the first spring 13 vibrates because the sliding plug 6 moves at a high frequency.

Meanwhile, under the capillary action, water in the water storage tank 8 rises to the water absorption fluff on the surface of the first spring 13 along the water absorption strip 12 and is broken into small water drops in the vibration process of the first spring 13, and the broken small water drops can be fully combined with the air containing smoke discharged by the exhaust pipe 9, so that the smoke is removed. So can be at the in-process that uses this device, the smog concentration near greatly reduced self-rescuer body 1 makes the flee personnel of wearing this device can see near road situation and fire situation clearly, alleviates the difficulty of the in-process of fleing.

In addition, the air outlet end of the exhaust pipe 9 can be aligned to the body part, the broken small water drops can form water mist when being discharged along with air flow and cover the body, and the water mist covered on the body can be quickly evaporated under the high-temperature condition of a fire disaster, so that the low-temperature condition of the body is kept, the combustion can be prevented under the fire disaster condition, and the dehydration caused by the water loss in the body can be avoided.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
