Abstract
The utility model discloses a dust and toxic gas resistant respirator consisting of case-hardened respirator covering on the mouth, nose and their surrounding parts on the face, provided with exhaust holes and breathing chamber on surface and at interior respectively and a air feed pipe with two ends connected with the breathing chamber and air conveyor respectively. The air feed pipe comprises case-hardened respirator and the upper and lower air feed pipes of air conveyor. The joint of the two pieces of air feed pipes forms an active juncture which can rotate freely. The utility model has the advantages of that the breathing chamber of the case-hardened respirator worn by operator can continuously feed the fresh air to the mouth and nose of the operator through the air feed pipes of the air conveyor and the mouth and nose of the operator are kept away from the dust and toxic and harmful gases in the externally operating ambient. Thus, the occurrences of occupational diseases may be prevented effectively and workers may be assured with a healthy breathing environment in operations. Enjoying assets of simple structure, low cost and convenient operation, this respirator is suitable for the operators working in mines and engaged in spray painting work.
Description
Technical field
The utility model relates to the dust proof and gas defence respirator of being engaged in dust atmosphere operation or toxic and harmful operating personnel use.
Background technology
At present, the personnel that are engaged in the dust atmosphere operation or are engaged in the toxic and harmful operation, for example mine down-hole mining personnel, the operating personnel that are engaged in surface lacquer lack a kind of operation and effective mouth mask of dust proof and gas defence of not influencing.Existing antidusting and anti-poisoning mask; it generally all is the filtering type structure; or sponge or multiple ply sterilization cotton yarn are set in the interlayer of mouth mask cloth, or filter paper, fiber charcoal filtering material are set in the mouth mask protective layer, what also have is combined into respirator with mouth mask and water filtering device.But, wear this filter-type respirator or respirator, can make the operating personnel feel worn-out gas, dry, inhibition eupnea; This mouth mask can only alleviate the harm of dirt, poison, really can not break away from dirt, poison to the infringement of people's respiratory apparatus, and wears this respirator and also influence staff's normal operation.
Summary of the invention
Goal of the invention of the present utility model is: for being engaged in the personnel of dust work or toxic and harmful operation, provide a kind of in the environment of toiling on, can effectively prevent occupational disease that normal operation, dust proof and gas defence respirator simple in structure take place, do not influence.
Invention order of the present utility model is realized by implementing following technical proposals:
A kind of dust proof and gas defence respirator, it is characterized in that: include enclosed hood muzzle and around on the face, its surface be provided with steam vent, in the typing mouth mask of breathing chamber is arranged, the snorkel that is communicated with typing mouth mask internal respiration cavity, and the air conveyor that is communicated with this snorkel.Additional technical feature is: described snorkel, and by the short snorkel of the epimere that is communicated with the typing mouth mask, reach the following segment length's snorkel that is communicated with air conveyor and form, this is the abutting end of two snorkels up and down, forms one for forming the movable connection structure that freely rotates.
Operation principle of the present utility model is as follows: when operation under mine, snorkel and air conveyor are connected, the workman wears the utility model typing mouth mask then, start air conveyor, fresh air is imported in the typing mouth mask respiratory cavity by snorkel, the workman can be in dust work the fresh air in the respirator, and the waste gas of breathing out is discharged by the steam vent on the typing mouth mask.Because snorkel can be very long, and snorkel has the syndeton that can freely rotate, the operating personnel turns round freely, does not influence the digging operation progress
Advantage of the present utility model is: because the operating personnel wears in the typing mouth mask respiratory cavity, there is continuously fresh air supply with by snorkel by air conveyor, nose, mouth do not contact dust and toxic and harmful in the external procedure environment, therefore can effectively prevent the generation of occupational disease, the respiratory health of workman in operation process is protected.Simultaneously, this respiratory organ structure is simple, cost is low, easy to use, is suitable for the digging personnel of down-hole, mine, the operating personnel that are engaged in surface lacquer use.
Description of drawings
Fig. 1 is the utility model structural representation
Mark among the figure: 1 is air conveyor, 2 is the following segment length's snorkel that is connected with air conveyor, and 3 is the movable connection structure that can freely rotate, and 4 is the short snorkel of epimere that is connected with the typing mouth mask, 5 are the typing mouth mask, and 6 for being arranged on the steam vent on the typing mouth mask.
The specific embodiment
A kind of dust proof and gas defence respirator, its surface be provided with steam vent 6, in the typing mouth mask 5 of breathing chamber is arranged, enclosed hood operating personnel's nose, mouthful and around on the face, the breathing chamber of typing mouth mask 5 is communicated with the short snorkel 4 of epimere, air-blaster 1 connects down, and the abutting end of 2, two sections snorkels of segment length's snorkel 4,2 forms the movable connection structure 3 that freely rotates and these two sections snorkels is formed one.
Claims (2)
1, a kind of dust proof and gas defence respirator, it is characterized in that: include enclosed hood muzzle and around on the face, its surface be provided with steam vent (6), in the typing mouth mask (5) of breathing chamber is arranged, the snorkel that is communicated with typing mouth mask (5) internal respiration cavity, and the air conveyor (1) that is communicated with this snorkel.
