Abstract
The utility model provides a one-way air inlet and outlet dust mask which comprises a mask and a filter, wherein the mask is communicated with the filter through an air inlet pipe and an air outlet pipe; the mask and the filter are both provided with an air inlet and an air outlet; the air outlet of the filter is located above a filtering cavity, and the air inlet of the filter is located above a waste-air discharge cavity; the air inlet end of the air inlet pipe is communicated with the air outlet of the filter, and the air outlet end of the air inlet pipe is communicated with the air inlet of the mask; the air inlet end of the air outlet pipe is communicated with the air outlet of the mask, and the air outlet end of the air outlet pipe is communicated with the air inlet of the filter; the air inlet pipe is provided with a light-weight one-way air inlet valve which is opened towards the air inlet of the mask; and the air outlet pipe is provided with a light-weight one-way air outlet valve which is opened towards the air inlet of the filter. The one-way air inlet and outlet dust mask is simple in structure and convenient to use and can ensure that breathing is smooth and fresh air is inhaled.
Description
Technical field
The utility model relates to a kind of mask, the dust mask that specifically a kind of unidirectional air inlet is given vent to anger.
Background technology
Existing dust suction mask generally all is to comprise a dust mask and filter; Then dust mask is communicated with filter through wireway; Its air inlet all is to carry through a pipeline with breathing, through regular meeting because admittance sluggish in air circulation causes problems such as the user can feel uncomfortable in chest, calms the anger, scorching and unsmooth breath.And air inlet and expiration adopt same pipeline, and the gas after can causing filtering mixes with the waste gas of exhalation, and the gas that breathing is entered is polluted, and is not health very.
Summary of the invention
The purpose of the utility model provides a kind of with air inlet with give vent to anger separately, and it is unimpeded to cause air inlet to be given vent to anger, and guarantees the dust mask that the unidirectional air inlet of the gas clean hygiene of incoming call is given vent to anger.
The dust mask that said unidirectional air inlet is given vent to anger comprises face shield and filter, and face shield is connected through wireway with filter, in filter, is provided with the toxic emission chamber; Below the toxic emission chamber, be provided with waste gas outlet, it is characterized in that: said wireway is made up of air inlet pipe and escape pipe, on face shield and filter, all offers air inlet and gas outlet; The gas outlet of filter is arranged on the filter chamber top; Air inlet is arranged on top, toxic emission chamber, and the inlet end of air inlet pipe is communicated with the gas outlet of filter, and the outlet side is communicated with the air inlet of face shield; The inlet end of escape pipe is communicated with the gas outlet of face shield; The outlet side is communicated with the air inlet of filter, on the pipeline of air inlet pipe, is provided with the lightweight one-way inlet valve of opening towards the face shield air inlet, on the pipeline of escape pipe, is provided with the unidirectional air outlet valve of opening towards the air inlet of filter of lightweight.
Be equipped with the filtration sponge at the air inlet place of waste gas outlet and filter.
Said lightweight one-way inlet valve and the unidirectional air outlet valve of lightweight all are to adopt light material to process, and control its switch through air-flow.
The beneficial effect of the utility model: air inlet pipe of the utility model and escape pipe are independent pipeline; And on air inlet pipe and escape pipe, be respectively equipped with light material one-way inlet valve and unidirectional air outlet valve; All open towards direction only, the negative pressure that utilizing exhales between face shield and the tracheae produces when air-breathing is controlled the switch of inlet valve and air outlet valve, controls air inlet and gives vent to anger; It is smooth and easy to ensure respiration, and breathing is with fresh air.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: the 1-face shield, the 2-filter, 3 air inlet pipe, the 4-escape pipe, 5 lightweight one-way inlet valve, the unidirectional air outlet valve of 6-lightweight, 7-filters sponge, 8 toxic emission chambeies, 9 waste gas outlets.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.Among Fig. 1, said. the dust mask that a kind of unidirectional air inlet is given vent to anger, it comprises face shield 1 and filter 2; Face shield 1 and filter 2 are connected through wireway, in filter 2, are provided with toxic emission chamber 8, below the toxic emission chamber, are provided with waste gas outlet 9; It is characterized in that: said wireway is made up of air inlet pipe 3 and escape pipe 4; On face shield 1 and filter 2, all offer air inlet and gas outlet, the gas outlet of filter 2 is arranged on the filter chamber top, and air inlet is arranged on 8 tops, toxic emission chamber; The inlet end of air inlet pipe 3 is communicated with the gas outlet of filter 2; The outlet side is communicated with the air inlet of face shield 1, and the inlet end of escape pipe 4 is communicated with the gas outlet of face shield 1, and the outlet side is communicated with the air inlet of filter 2; On the pipeline of air inlet pipe 3, be provided with the lightweight one-way inlet valve 5 of opening, on the pipeline of escape pipe 4, be provided with the unidirectional air outlet valve of opening towards the air inlet of filter 26 of lightweight towards face shield 1 air inlet.
Be equipped with filtration sponge 7 at the air inlet place of waste gas outlet 9 and filter 2.
Said lightweight one-way inlet valve 5 all is to adopt light material to process with the unidirectional air outlet valve 6 of lightweight, and controls its switch through air-flow.
During use, filter 2 is fixed on user's waist, face shield 1 is placed on the face; When air-breathing, certain air pressure is arranged in the air inlet pipe 3, because the flow path direction of the opening direction of lightweight one-way inlet valve 5 and air pressure always; Lightweight one-way inlet valve 5 just can be opened; And the opening direction of the unidirectional air outlet valve 6 of lightweight is just opposite with airflow direction, just closes automatically, and fresh air just gets into face shield along air inlet pipe; When giving vent to anger, on the contrary, the unidirectional air outlet valve 6 of lightweight is opened, and lightweight one-way inlet valve 5 is closed automatically, and the waste gas of exhalation is discharged through the discarded outlet on the filter 29 just along escape pipe 4 inflow filters again.
