Abstract

The utility model discloses an air filtering device containing a respiratory conduit having a direct connection with respiratory tract and filter with plurality of inlet air which can realize a filtering of air entering into the respiratory conduit. The device may resist against backwards flow completely. Connected with the respiratory tract directly, the device is therefore free from the influence of different shapes of faces. Equipped with the filtering cores with plurality of inlet air, the device may realize a full filtering of air without any influence imposed by the relative positions of devices.

Description

Air filter

Technical field

The utility model relates to a kind of labor protection device of air cleaning, relate in particular to a kind ofly be used for mouthful, air filter that nasal respiration is used.

Background technology

Mouth mask now commonly used generally is to cover mouth and nose simultaneously, use the multi-layered gas-permeable gauze, and the centre accompanies cotton layer or filter course, enters the human respiratory tract by gauze layer and filter course again with dust in air, impurity, after being harmful to filtrations such as germ or gas.But it is because too near between respiratory tract and the gauze every getting; and human body is in the exhalation body during waste gas; also can have the exchange of heat; make often to assemble in the gauze steam is arranged; be bonded near the skin of respiratory tract; or be to increase an air chamber so that air enters respiratory tract again after fully filtering, do not allow skin directly contact with the filtration gauze.But under the usual condition, extraneous air, the air that filters gauze and enter respiratory tract have a specific order comparatively speaking, position between each device is certain comparatively speaking, air inlet necessarily can only be arranged on and filter after the gauze, in case a certain partial devices wherein moves or places mistake, will influence the quality that enters the respiratory tract air at last.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned technology and a kind of air filter that the multilayer air intake filter is arranged is provided.

The utility model can will be realized by following technical proposals:

This air filter includes the corrugated hose that directly links to each other with respiratory tract and will enter many air intake filters that the air in the corrugated hose filters.

Also include air chamber, air chamber communicates with an end of corrugated hose, and air chamber also communicates with an end of blast pipe, and other has air inlet pipe to connect many air intake filters and air chamber.

Be provided with the breather check valve door in the described air inlet pipe.

Be provided with double gas check valve in the described blast pipe.

Described venting check valve is provided with spring or flatwise is gently pressed check-valves.

Described corrugated hose comprises nipple that communicates with oral area and the nose larynx that communicates with nose.

Described many air intake filters comprise filter chamber and the filter core of crossing that is arranged at wherein, and air inlet pipe was inserted in the filter core, cross to comprise successively between filter core outermost layer and the air inlet pipe that many inlet air filtrations net and filter chamber dredge square.

Described many air intake filters comprise the filter chamber, and filter chamber's one end communicates with air inlet pipe, and the other end is provided with the coarse filtration net, is provided with many inlet air filtrations net in the filter chamber, and air inlet pipe is provided with the active carbon core; The air inlet pipe appropriate location is provided with pressurized feed pump midway.

Described filter chamber is outside equipped with bucker.

Be connected with in order to fix being linked with of this device on described many air intake filters.

By technique scheme, thereby this utility model has following beneficial effect:

1. anti-backflow fully;

2. directly be connected with respiratory tract, thereby not influenced by the different shapes of face of different people;

3. have many inlet air filtrations core, thereby can fully and not be subjected to respectively to install the influence of relative position air filtration.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is made further instruction.

Shown in Figure 2 as Fig. 1, this utility model include with breathe in oral area, nipple 1 and nose larynx 2 that nose directly links to each other respectively and will enter many air intake filters 3 that the air in the corrugated hose filters.Also include air chamber 4, air chamber communicates with an end of corrugated hose, and air chamber also communicates with an end of blast pipe 5, and other has air inlet pipe 6 to connect many air intake filters and air chamber; Be provided with breather check valve door 62 in the described air inlet pipe; Be provided with double gas check valve 52 in the described blast pipe; Venting check valve is provided with spring 522.And described many air intake filters comprise filter chamber 32 and the filter core 34 excessively that is arranged at wherein, and air inlet pipe was inserted in the filter core, cross to comprise successively between filter core outermost layer and the air inlet pipe that many inlet air filtrations net 342 and filter chamber dredge square 344; Can also outside the described filter chamber bucker 7 be set, and a drain plug 8 be set, when because after the steam that exhalation vents and air entry produce after temperature exchange is arranged too much condenses into water, turn on the drying that drain plug can be guaranteed air chamber in the air chamber lower end.Compared with prior art, thus following advantage is arranged: full anti-backflow; Directly be connected with respiratory tract, thereby not influenced by the different shapes of face of different people; Have many inlet air filtrations core, thereby can fully and not be subjected to respectively to install the influence of relative position air filtration.

Figure 4 shows that the utility model second embodiment as Fig. 3, the difference of itself and first embodiment is: the oral area in including and breathing, the nipple 1 ' that nose directly links to each other respectively is with nose larynx 2 ' and will enter many air intake filters 3 ' that the air in the corrugated hose filters, many air intake filter 3 ' sealings are provided with, thereby not only can the air filtration of respiratory tract will be entered, the also gas filtration that can breathe out from respiratory tract, thereby can avoid cross-infection, and many inlet air filtrations core directly is connected with corrugated hose, also be provided with in addition and be linked with 9, perhaps also can without fixed band in order to this device is fixed in the human body face proper site.Small and exquisite and light, adapt to child and women and use.

As Fig. 5 is many air intake filters schematic diagram of the utility model the 3rd embodiment, its difference with first embodiment is: filter chamber's 32 ' one end communicates with air inlet pipe 6 ', the other end is provided with coarse filtration net 320 ', in the filter chamber, be provided with many inlet air filtrations net 322 ', be outside equipped with bucker 7 ' in the filter chamber, air inlet pipe is provided with active carbon core 64 '; The air inlet pipe appropriate location is provided with pressurized feed pump 10 midway, can increase air pressure, make supply gas more smooth and easy, thereby need being fit to uses in a large number with the gas person.
