Abstract

The invention discloses a frog type respirator which comprises a body. The body comprises an isolation cavity. A filter layer is arranged on the front wall of the isolation cavity. An air inlet channel is arranged at the lower end of the isolation cavity. The two sides of the isolation cavity are each connected with an exhaust chamber through an inner valve. Outer valves are arranged on the outer sides of the exhaust chambers. An air blowing cavity is formed in the position of the air inlet channel at the lower end of the isolation cavity. An air blowing blade is arranged in the air blowing cavity and connected with a motor and a battery in a battery mounting area. According to another frog type respirator, an air inlet channel is arranged at the lower end of an isolation cavity and connected with an external air filter through a hose, the two sides of the isolation cavity are each connected with an exhaust chamber through an inner valve, and outer valves are arranged on the outer sides of the exhaust chambers. An expiration channel and an inspiration channel in the respirator are separated, the area of the filter layer is increased, the inspiration channel is connected, and therefore inspiratory resistance is reduced; and a channel is additionally formed for expiration, expiration air is directly exhausted out of the expiration channel through valves, exhaust resistance is small, and respiration is very smooth through the comprehensive effect.

Description

Frog breathing device

Technical field

The present invention relates to a kind of Worn type respirator, belong to and breathe equipment manufacture field.

Background technology

When dust exceeding in air, the most frequently used method wears mouth mask, can wear the respirator with filter when dust severe overweight.But wear mouth mask for a long time or respirator all can feel unhappy, namely sensation is breathed very hard, tradition mouth mask causes and breathes hard reason is that filter course directly stops expiration and air-breathing, although most of dust can be stopped, but cause and breathe difficultly, and the filter course of respirator can not be very large due to normal section, equally can because to exhale and air-breathing all will cause through this cross section and breathes difficultly.

Summary of the invention

The object of this invention is to provide and a kind ofly can reduce the resistance that filter course causes and make to breathe frog breathing device smoothly.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of frog breathing device, comprise body, body comprises separate cavities, and the antetheca of separate cavities is provided with filter course, and separate cavities lower end is provided with inlet channel, and the both sides of separate cavities are respectively connected with exhaust chamber by inner valve, and the arranged outside of exhaust chamber has outer valve.

Exhaust chamber is fixed by fixed bar and separate cavities.

Inlet channel place, separate cavities lower end is provided with air blast chamber, and air blast is provided with airblast blade in chamber, and airblast blade connects the battery of motor and Battery compartment.

Air blast cavity wall face is provided with air blast chamber surface filtration layer, and air blast cavity wall is also provided with pressure sensor and control circuit board.

Another kind of frog breathing device, comprise body, body comprises separate cavities, separate cavities lower end is provided with inlet channel, inlet channel connects extraneous air filter by flexible pipe, and the both sides of separate cavities are respectively connected with exhaust chamber by inner valve, and the arranged outside of described exhaust chamber has outer valve.

The invention has the beneficial effects as follows:

The present invention takes the exhalation passages in respirator and air intake passage to separate, increasing filter course area and connecting air intake passage makes inspiratory resistance reduce, to exhale another open walk, exhalation passages directly discharges expiration through one to two valve, not only pass through filter course to discharge, exhaust resistance is little, and resultant effect makes breathing very smooth and easy.Use frog breathing device of the present invention to make to breathe smooth and easy, can wear for a long time, simultaneously can effective preventing pollution air being mixed into when air-breathing, can be used for the dust in effective filtered air, and make breathing smooth and easy.

Detailed description of the invention

embodiment 1

A kind of frog breathing device, comprise body, body comprises separate cavities 1, the antetheca of separate cavities 1 is provided with filter course 1A, separate cavities 1 lower end is provided with inlet channel 6, and the both sides of separate cavities 1 are respectively connected with exhaust chamber 2 by inner valve 3A, and the arranged outside of exhaust chamber 2 has outer valve 3B.

Exhaust chamber 2 is fixed by fixed bar 4 and separate cavities 1.

Inlet channel 6 place, separate cavities 1 lower end is provided with air blast chamber 7, and be provided with airblast blade 8 in air blast chamber 7, airblast blade 8 connects the battery of motor 9 and Battery compartment 10.

Air blast chamber 7 internal face is provided with air blast chamber surface filtration layer 7A, and air blast chamber 7 inwall is also provided with pressure sensor and control circuit board.

Separate cavities 1 is manufactured according to the shape of face of people, separate cavities 1 can be made with plastics or metal, the inner surface of separate cavities 1 manufactures filter course 1A and can pass through air, and the edge manufacture that separate cavities 1 contacts with face has flexible foam plastic, can be close to face when straining to face.Circular row air chamber 2 is manufactured with elastoplast, exhaust chamber 2 and separate cavities 1 junction manufacture inner valve 3A, the outside of exhaust chamber 2 manufactures outer valve 3B, manufacture fixed bar 4 for exhaust chamber 2 being fixed on the both sides of separate cavities 1, connect contiguous block 5 with elastic cord or hasp around head, make separate cavities 1 to be close to face.

Wall around air blast chamber 7 settles air blast chamber surface filtration layer 7A, air can be passed through, at this space wall setting pressure sensor and control circuit board, when air pressure is greater than normal pressure, such as when exhaling, cut off circuit, air-blowing stops, when air pressure is less than normal pressure, such as during air-breathing, connect circuit, air-blowing starts.Pressure sensor and control circuit board can be saved in order to reduce costs, the switch of an electronic air-blowing device is only installed.

embodiment 2

As shown in Figure 3 and Figure 4, body comprises separate cavities 1, separate cavities 1 lower end is provided with inlet channel 6, inlet channel 6 connects the inlet channel 11 of extraneous air filter by flexible pipe and then connects extraneous air filter, the both sides connecting separate cavities 1 are respectively connected with exhaust chamber 2 by inner valve 3A, and the arranged outside of exhaust chamber 2 has outer valve 3B.

The cavity 14 inner filtration layer surface 13 connecing extraneous air filter is provided with extraneous air metre filter layer 15, the expiration of inlet channel Valve controlling is closed air-breathing and is opened, and extraneous air filter can be worn on head or health by extraneous air filter contiguous block 12.

The filter course sectional area of filter will manufacture large as far as possible, filter can be placed in head or with it.Exhalation passages 6 is connected to exhaust chamber 2 by inner valve 3A, and exhaust chamber 2 is vented by outer valve 3B.Settle exhaust chamber 2 be in order to when being transformed into air-breathing, inner valve and outer valve closing in a flash because there is the existence in exhaust chamber space can reduce being mixed into of outside contamination air as far as possible.Exhaust chamber 2 can be made with soft elastic material, has agitate phenomenon, so be called frog breathing device when being vented.The exhaust chamber 2 made of soft elastic material is inner when being vented can cause less malleation that exhaust chamber is heaved, this malleation exhale convert air-breathing to can stop being mixed into of outside contamination air in a flash.People discharges except exhaling from exhaust chamber when exhaling, and also has sub-fraction to discharge from the filter course of insulating space.
