Description

Portable respirator with liquid filtering function

Technical Field

The utility model belongs to the public health field relates to a portable respirator that has liquid filtering capability.

Background

At present, the breathing device has the following several kinds, the first kind is the fixed large-scale breathing machine on ground, this kind can not carry, the second kind is, has very long pipe, and the air-blower is put on ground, send the air to the face guard through the pipe in, this kind also can not carry, the third kind is to use micro-fan, will pass through the filterable air of filter core and send the air to the face guard through the pipe, this kind needs special filter core, does not have liquid filtering capability, does not use medical gauze mask as the filter core, the filtration link only has a filter core to filter. The fourth is head-wearing type, which is designed with a breather valve and a filtering device, and this also needs special filter elements, and all special filter elements are not medical standard filter elements, and because of the head-wearing type, the weight and the volume are limited, batteries, motors and the like can not use heavy and large, the filtering links are few, and the liquid filtering function is not provided. And the air compression pump is used as an air source and is filtered by the liquid filter box filter element, so that the air compression pump has the advantages of large vibration, large noise and short service life of the motor.

A portable respirator with liquid filtering function is suitable for the closed occasions of intensive care units, subways, motor cars, elevators and the like in hospitals and can prevent viruses, dust and the like from being inhaled.

Utility model content [0004]

The utility model aims at providing a portable respirator with liquid filtering function, the filter core adopts a medical disposable mask with more than 95 percent of filtering rate as the filter core, the air is filtered by the filter core and the active carbon layer, and after being filtered by the liquid honey and filtered by water, harmful substances such as aerosol, virus and the like are filtered by the liquid honey and the water, thereby not only ensuring the filtering effect, but also reducing the use cost, and the cost is low because the filter core uses the disposable medical mask; meanwhile, the utility model is convenient for the user to replace at any time; through the transmission of electric fan, the user breathes smoothly.

The technical scheme adopted by the utility model is that the portable breathing device with the liquid filtering function comprises a power supply, a fan, a liquid box, a battery, a switch and the like which can be put into a satchel and are convenient to carry, wherein the liquid box is provided with a hollow column; comprises a honey chamber and a water filtering chamber; the honey filter is provided with a honey partition plate and a water filter partition plate, an air inlet filter box is arranged at the top end of a hollow column, three layers of filter elements are arranged in the box, an upper filter element and a lower filter element are medical 95% masks which are cut into filter elements, an activated carbon layer is arranged in the middle of the filter elements, a suction force is generated when a fan works, air entering the hollow column is firstly filtered by the masks with the filter rate of 95% and the activated carbon layer, cleaner air enters the bottom of liquid honey in a honey chamber, air coming out of the honey chamber enters a sandwich channel between the honey partition plate and the water filter partition plate through a top gap of the honey partition plate and enters the water bottom, the air comes out of water through a lower gap of the water filter partition plate, enters the fan after moisture is filtered by a water filtering sponge, the air enters a latex mask through an air guide pipe from an outlet of the fan, the cleaner air reaches, except over breathing, the surplus air is discharged to the outside through the face guard, so that the user can breathe the filtered clean air through a plurality of modes even in a severe environment, and basically, the air is not sucked from the outside of the mask, so that the safety of the user is ensured, and the filter element is a disposable medical mask except the over-active carbon filter element, so that the use cost is low.

Adopt above-mentioned technical scheme the utility model discloses compare with prior art, have following advantage: the liquid box is provided with a honey chamber and a water filtering chamber, the honey chamber and the water filtering chamber are provided with hollow columns, the top end of each hollow column is provided with an air inlet filtering box, and when the fan works, suction force is generated, so that air is filtered by a medical mask and an active carbon layer in the air inlet filtering box, and then filtered by liquid honey and water, and the filtering rate of the medical mask is more than 95%, so that the filtering effect is ensured, and the replacement of a user is facilitated; the cost is low; utilize the viscidity of honey, at the in-process that the air passed from liquid honey, impurity in the filtering air, including harmful substance such as aerosol, filter the back through water again, the air is just cleaner.

The utility model discloses a characteristics still lie in: the honey filter is provided with a liquid tank, a honey chamber and a water filtering chamber are arranged in the liquid tank, an interlayer channel formed by a honey partition plate and a water filtering partition plate is arranged in the liquid tank, and the flow generated by a fan can be adjusted through two stages of power switches; except the air for breathing, the redundant air can be input into the back of the user through the conduit to reduce the temperature, and the water filter chamber is used in summer due to the action of the water stored in the water filter chamber, so that the temperature is obviously reduced. In the honey chamber, the used filter liquid is honey liquid, the viscosity of the liquid honey is used for filtering small molecular substances such as aerosol of about 0.01um and the like, and the mask can only filter substances of more than 0.07um, so that the loophole of the mask filtration is made up. The water in the water filter chamber is used for secondarily purifying the air. The filter element in the air inlet filter box adopts a mask with disposable medical filtration rate of more than 95 percent, so the use cost is low, the mask is directly discarded after use, and the air inlet filter box also has an active carbon filter layer which utilizes active carbon and micro-aperture to filter air. In the use, if break down, the fan has not worked, and the user directly uses the latex face guard to breathe, does not delay the use, and the effect does not have liquid filtering capability portable respirator good only. Water and liquid honey in the liquid tank can be discharged through the inlet and outlet after being used for a period of time, and can be continuously used after being cleaned and disinfected by 75% alcohol.
