Abstract
The utility model relates to a simple outdoor air-inducing breathing mask which comprises a mask main body and an air pump. The simple outdoor air-inducing breathing mask is characterized in that the mask main body is provided with an air inlet and a unidirectional vent valve, a tapered barrel-shaped noise-reducing barrel is installed on the air inlet, a thin end of the noise-reducing barrel is connected with the air pump through a connecting hose, and the air pump is connected with an outdoor air-inducing pipe. The simple outdoor air-inducing breathing mask has the advantages that the air in the working environment can be thoroughly isolated, outdoor fresh air is led into the mask through the air pump, and users can genuinely breathe the outdoor pollution-free fresh air.
Description
Technical field
The utility model relates to a kind of simple and easy outdoor air inducing breathing mask, belongs to gas defence dust mask field.
Background technology
Existing gas defence dust mask comprises a profiling rubber mask main body according to people's shape of face design; On the mask main body, be provided with air inlet and unidirectional air outlet valve; Be provided with the single or multiple lift filter course of being processed by filter paper or active carbon at the air inlet place, the mask main body can be held on people's the cheek oronasal mask in the mask main body.
Though this type mask can filter air, the filtered air of the smog that produces in the still working environment that the staff breathed, dust, toxic and harmful can not fundamentally solve the breath purifying problem.
Summary of the invention
The purpose of the utility model provides a kind of can thoroughly completely cutting off the working environment air, and outdoor fresh air is introduced in the mask, really let the user can breathe the simple and easy outdoor air inducing breathing mask of fresh air.
The purpose of the utility model is realized by following mode:
The utility model comprises mask main body, air pump; It is characterized in that: on the mask main body, be provided with air inlet and one-way exhaust valve; The noise abatement tube of taper tubular is installed on air inlet, and the thin end of noise abatement tube connects air pump with connecting flexible pipe, is connected with outdoor induced duct on the air pump.
The utility model has the advantages that: can be thoroughly isolated the working environment air, outdoor fresh air is introduced in the mask, really let the user can breathe outdoor free of contamination fresh air through air pump.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
With reference to accompanying drawing, the utility model comprises mask main body 1, air pump 8, on mask main body 1, is provided with air inlet 5 and one-way exhaust valve 2; One-way exhaust valve 2 is at least two; One-way exhaust valve 2 is made up of plastic skeleton 3 and the rubber film 4 that is installed in plastic skeleton 3 outsides, and the noise abatement tube 6 of taper tubular is installed on air inlet 5, and the thin end of noise abatement tube 6 connects air pump 8 with connecting flexible pipe 7; Air pump 8 is an electromagnetic air pump, is connected with outdoor induced duct 9 on the air pump 8.In use, the end of outdoor induced duct 9 need be placed on outdoor, so the length of outdoor induced duct 9 may be very long; If there is not the active air inducing of air pump 8, the people is difficult to breathe air through thinner induced duct, so must be equipped with air pump; Passive air inducing is become initiatively air inducing, and through air pump air inducing, the air-flow of introducing is stronger; So on mask main body 1, two one-way exhaust valves should be set at least, smooth and easy to guarantee exhaust; Owing to be active air inducing, so air-flow can produce noise when getting into the mask main body, noise abatement tube 6 is installed on air inlet 5 can effectively abate the noise.
Claims (2)
