Abstract
The utility model discloses a mining breathing mask which comprises a mask main body (2). The mask main body is used for covering the face of a wearer. The mining breathing mask is characterized in that a first cavity and a second cavity are respectively formed in the mask main body (2), the first cavity and the second cavity are respectively arranged at the periphery of the mouth of the wearer and at the periphery of the nose of the wearer when being used, the first cavity and the second cavity are respectively communicated with one end of a first air pipe (4) and one end of a second air pipe (6), an opening is formed in the other end of the first air pipe (4), the other end of the second air pipe (6) is communicated with an oxygen bottle (8), the first air pipe (4) and the second air pipe (6) are respectively connected with one-way air valves (10 and 12) where air can only enter in a one-way mode, and air inlets (14) of the one-way air valves (10 and 12) are respectively connected with the oxygen bottle (8) and a first accommodating cavity. When the wearer wears the mining breathing mask, the nose can only inhale but not exhale. Thus, waste gas cannot flow back into the oxygen bottle (8). The mouth can only exhale but not inhale, so that the waste gas can be exhausted through the mouth. Due to the fact that the mouth cannot inhale, the using safety is improved.
Description
Technical field
The utility model relates to a kind of mining self-help apparatus, is a kind of breathing mask specifically.
Background technology
Self-rescuer is that coal mine underground operators runs into the disaster such as fire, blast, Gas Outburst and lives other place oxygen supply conditions when not enough, and a kind of safety equipment of escaping for absence from work without reason, can be divided into filter type self-rescuer and oxygen-producing type self-rescuer according to operation principle.
Oxygen-producing type self-rescuer, as the term suggests be exactly a kind of self-rescuer that oxygen can be provided for disaster affected people, common oxygen-producing type self-rescuer comprises with oxygen cylinder breathing mask, breathing mask of the prior art can only cover nose under normal circumstances, when breathing, nose is oxygen intake from oxygen cylinder, then by mouth, waste gas is discharged.But in the time that dangerous situation occurs, not all people can both keep such breath rhythm, accidentally breathe through one's mouth, so very likely the waste gas in air is sucked to threat to life.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of safe breathing mask.
For addressing the above problem, the utility model provides a kind of mining breathing mask, comprise the mask body for covering wearer's face, it is characterized in that, in described mask main body, be also respectively arranged with in use time-division first cavity and second cavity of confession around wearer's mouth and around nose indescribably, described the first cavity and the second cavity are communicated with one end of the first tracheae and the second tracheae respectively, the other end opening of described the first tracheae, the other end of described the second tracheae is communicated with an oxygen cylinder, only on described the first tracheae and the second tracheae, be all connected with can one-way air inlet Non-return air valve, the air inlet of described Non-return air valve is communicated with described oxygen cylinder and the first cavity volume respectively.
As further improvement of the utility model, between the air inlet of described Non-return air valve and gas outlet, be provided with a passage, in this passage, be provided with it vertical cut off and be netted the first baffle plate and second baffle of ventilating, described the first baffle plate is provided with the through hole being communicated with described air inlet, on described the first baffle plate, be also provided with and connect a spring, the other end of described spring is connected with a bulb stopper that is stuck in described through hole aperture, and the diameter of this bulb stopper is greater than the diameter of described through hole.
As further improvement of the utility model, on described bulb stopper, be also fixedly connected with a suction disc, described suction disc is parallel with described the first baffle plate.
As further improvement of the utility model, on described oxygen cylinder, be also fixedly connected with braces.
The beneficial effects of the utility model are, adopt the utility model, and when user uses mask, nose only can air-breathingly can not be exhaled, and ensure that waste gas can not flow back in oxygen cylinder; And face only can exhale can not be air-breathing, can waste gas be discharged by face, and can not be air-breathing by face.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further details.
As depicted in figs. 1 and 2, the utility model provides a kind of mining breathing mask, comprise the mask body 2 for covering wearer's face, in described mask main body, be also respectively arranged with in use time-division first cavity and second cavity of confession around wearer's mouth and around nose indescribably, described the first cavity and the second cavity are communicated with one end of the first tracheae 4 and the second tracheae 6 respectively, the other end opening of described the first tracheae 4, the other end of described the second tracheae 6 is communicated with an oxygen cylinder 8, only on described the first tracheae 4 and the second tracheae 6, be all connected with can one-way air inlet Non-return air valve 10, 12, described Non-return air valve 10, 12 air inlet 14 is communicated with described oxygen cylinder 8 and the first cavity volume respectively.
In the utility model, when user's nose is air-breathing, Non-return air valve 12 is opened, and the oxygen in oxygen cylinder 8 enters the second tracheae 6 and sucked by nose, and in the time that user's nose is exhaled, check valve 12 is closed.Now, nose only can air-breathingly can not be exhaled, and ensures that waste gas can not flow back in oxygen cylinder 8; And user's face is while exhaling, Non-return air valve 10 is opened, and the waste gas in face discharges by the first tracheae 4, and in the time that user use face is air-breathing, Non-return air valve 10 is closed.Now only can exhale can not be air-breathing for face, can waste gas be discharged by face, and can not be air-breathing by face, prevent that the waste gas in air is inhaled in face.
As further improvement of the utility model, between the air inlet 14 of described Non-return air valve and gas outlet 16, be provided with a passage 18, in this passage 18, be provided with it vertical cut off and be netted the first baffle plate 20 and second baffle 22 of ventilating, described the first baffle plate 20 is provided with the through hole 24 being communicated with described air inlet 14, on described the first baffle plate 20, be also provided with and connect a spring 26, the other end of described spring 26 is connected with a bulb stopper 28 that is stuck in described through hole 24 apertures, and the diameter of this bulb stopper 28 is greater than the diameter of described through hole 24.
Adopt this Non-return air valve 10,12, when blowing to air inlet 14 or when air-breathing to gas outlet 16, bulb stopper 28 is under the effect of the power of blowing or suction, leave through hole 24, now whole passage 18 will connect, and gas can pass through this passage 18, and blows or air-breathing to gas outlet 16 to air inlet 14, cannot make bulb stopper 28 separate with through hole 24, cause whole passage 18 obturations, gas cannot pass through, the Non-return air valve 10,12 of this structure, construct uncomplicatedly, use more convenient.
As further improvement of the utility model, on described bulb stopper 28, be also fixedly connected with a suction disc 30, described suction disc 30 is parallel with described the first baffle plate 20.
