Abstract
A kind of breathing mask with filter dump valve of the present utility model, comprise breathing mask body and dump valve, described breathing mask body is provided with breathing regulator interface, and connect breathing regulator (not shown) by breathing regulator interface, be provided with outlet in mask body bottom position simultaneously, this outlet end is provided with passing away, and is provided with support barrier.Its main points of the utility model are also that described outlet is provided with dump valve, and this dump valve is provided with discharges check valve sheet and filter.This filter comprises filtration barrier and screen pack.The utility model efficiently solves under the environment that water quality is bad, the foreign material such as the silt in water easily enter in face shield by outlet passage, final blocking or block air-breathing or discharge check valve sheet, causes air-breathing or discharges check valve sheet action malfunctioning, and causing cannot the problem of eupnea.
Description
Technical field
The utility model relates to a kind of breathing mask with filter dump valve, its respirator apparatus class belonging to diving or use in the bad environment of water quality.
Background technology
Existing this type of general breathing mask mainly comprises mask body, and general mask body is provided with breathing regulator interface and mouth for subsequent use.Described breathing regulator is second depressurized device, and gas reaches needed for the breathing of people through decompression.The air inlet of this breathing regulator connects with gas cylinder, and breathing regulator body also establishes exhaust outlet.During the work of this type of breathing mask, during user's air-breathing, suction one-way valve opens in the breathing regulator that face shield is external, air is derived and is supplied user through reduced pressure treatment from gas cylinder, during expiration, the suction closed check valve in respiratory air box, discharges one-way valve opens, the gas of breathing out is discharged to exhaust outlet by the discharge check valve opened, and is discharged in the external world eventually through exhaust outlet.Foregoing breathing mask is generally less compliant in water and uses, and is especially not suitable for using in the poor environment of condition of water quality is as mine perviousness.An outlet is not established, to solve the problem entering water in breathing mask or air and discharge in general breathing mask bottom.Though minority is provided with outlet in mask body bottom, directly communicate between its outlet with discharger.This breathing mask, as used under the environment of condition of water quality difference, impurity in water etc. are as easy as rolling off a log to be entered in discharger and breathing mask when user breathes by outlet, block or block air-breathing or discharge check valve sheet, cause air-breathing or discharge check valve sheet sealing incessantly malfunctioning, end user cannot eupnea, occurs unsafe condition.For this reason, the breathing mask of Novel belt filter dump valve improves for this problem.
Summary of the invention
The purpose of this utility model is to provide a kind of breathing mask with filter dump valve, to solve prior art Problems existing.
A kind of breathing mask with filter dump valve of the present utility model, comprise breathing mask body, described breathing mask body is provided with breathing regulator interface, and connect breathing regulator (not shown) by breathing regulator interface, be positioned at breathing mask body lower position and be provided with outlet.
A kind of breathing mask with filter dump valve of the present utility model, is characterized in that described outlet end is provided with passing away, and is provided with support barrier.The setting of this support barrier thus guarantee there is the flowing space between passing away.
A kind of breathing mask with filter dump valve of the present utility model, is characterized in that its foot outlet described is provided with dump valve.This dump valve is provided with discharge check valve sheet.
A kind of breathing mask with filter dump valve of the present utility model, as further improvement, this dump valve is provided with filter.Can enter in face shield by outlet by the foreign material such as silt effectively in filtered water, and cause air-breathing or discharge check valve sheet malfunctioning, thus improve the security reliability of use.In existing breathing mask, Problems existing is solved effectively.
As further improvement, described filter comprises screen pack and filters barrier, and this filtration barrier is screwed on dump valve port, and this screen pack is arranged between filtration barrier and passing away.This screen pack is selected as stainless steel braided metal screen pack, more durable in use like this and resistant to rust.
A kind of breathing mask with filter dump valve of the present utility model, is characterised in that described filter screen filtration precision is 80-100 order altogether, can meets use needs like this, be unlikely to again to bring excessive pressure drag.
Accompanying drawing explanation
A kind of breathing mask structure schematic diagram with filter dump valve that Fig. 1 provides for the utility model preferred embodiment.
Fig. 2 is the A close-up schematic view of Fig. 1.
In each figure, 1 be breathing mask body, 11 for breathing regulator interface, 12 for outlet, 13 for passing away, 14 for support barrier, 2 for dump valve, 3 for discharge check valve sheet, 4, filter, 41 screen packs, 42 filter barriers.
Detailed description of the invention
A kind of breathing mask with filter dump valve provided below with reference to the utility model preferred embodiment and accompanying drawing are described in further detail concrete enforcement of the present utility model.
A kind of breathing mask with filter dump valve that the utility model preferred embodiment provides, comprise breathing mask body 1, described breathing mask body 1 is provided with breathing regulator interface 11, and connects breathing regulator (not shown) by breathing regulator interface 11.This mask body 1 is also provided with outlet 12, and described outlet 12 is positioned on breathing mask body 1 bottom position.
In this preferred embodiment, this outlet 12 end described is provided with passing away 13, and is provided with support barrier 14.The setting of this support barrier 14 thus guarantee there is the flowing space between passing away 13.
In this preferred embodiment, it is characterized in that this outlet 12 described is provided with dump valve 2.This dump valve 2 is provided with discharges check valve sheet 3.
In this preferred embodiment, this dump valve 2 described is provided with filter 4.
In this preferred embodiment, this filter 4 comprises screen pack 41 and filters barrier 42, and this filtration barrier 42 is screwed on dump valve 2 port, and this screen pack 41 is arranged between this filtration barrier 42 and passing away 13.This filtration barrier 42 pairs of screen packs 41 play the effect of location and anti-loose distortion.
In this preferred embodiment, this screen pack 41 described is stainless steel braided metal screen pack, more durable in use in this preferred embodiment like this, and this screen pack 41 filtering accuracy described is 80-100 order, use needs can be met like this, be unlikely to again to bring excessive discharge pressure.
In sum, a kind of breathing mask with filter dump valve of the present utility model, comprise breathing mask body 1, described breathing mask body 1 is provided with breathing regulator interface 11, and be connected with diving breathing regulator (not shown) by breathing regulator interface, also be provided with outlet 12 at this cover body 1 foot, this outlet 12 is provided with dump valve 2, and dump valve 2 is provided with discharges check valve sheet 3 and filter 4.
The utility model solves existing breathing mask in the environment that water quality is bad, uses the problem that cannot overcome.The foreign material such as the silt in water enter in face shield easily via outlet passage, finally block or block air-breathing or discharge check valve sheet, cause air-breathing or discharge check valve sheet action malfunctioning, and causing cannot the safety problem of eupnea.
And resistant to rust.
