Abstract
The utility model discloses a portable manual electric arc welding gasproof and dustproof helmet, belonging to a necessary labor protection commodity. Apart from playing a good role of protecting thermal radiation and strong light as general manual arc welding helmet, the utility model greatly solves the problem that the great welding ground flying dust can directly harm workers' body health. The utility model is provided with a miniature air pump which can add pressure to the air filtered by a gasproof and dustproof can and makes the gasproof and dustproof can, the miniature air pump, an adjusting valve sealed in a body cavity of an integrative forming box. Worker can breathe the air which is gasproof and dustproof and the air is processed by adding pressure.
Description
This utility model is the labor protection apparatus of welder's indispensability; specially refer to and to prevent that toxic gas and flue dust are to Welder's physical impairment and portable gas defence dust mask; can improve the welding job environment effectively, reduce labor strength, enhance productivity.
Manual arc welding mask in using now; can only play buffer action to the heat radiation and the high light of electric arc; protection workman's eyes and face are without prejudice; the poison gas and the flue dust that produce in the time of but can not preventing to weld effectively; in the existing welding healthy prevention measure, force ventilation, electrostatic filter are arranged.But because of it is invested greatly, difficulty of construction is high, only be applicable in the concentrated special-purpose Factory Building of welding job, the workshop, be difficult to apply in the industrial and mining establishment throughout the country.The personal protection face shield and the mask that also have, also big because of its air feed equipment complexity, volume, use inconvenient defective or because of its unpowered supercharging, the workman cries and exhales resistance to use sense of discomfort to be difficult to accept as the operator greatly or because of respiratory organ structure is unreasonable, long-time.
The purpose of this utility model is to overcome deficiency of the prior art, designs a kind of arc welding gas defence dust mask simple in structure, easy to carry.
Technical solution of the present utility model is: be provided with the micro air pump that the air through filtering after dustproof jar of poison filters is carried out supercharging, supported by ball-type pad grain between the base that is arranged on the respiratory organ in the face shield and the respiratory organ chamber and form cavity.The dustproof jar of filter poison, battery case, micro air pump and control valve four parts are packaged in the box body chamber of a global formation.
Accompanying drawing has been described a specific embodiment of the present utility model.
Fig. 1 is this utility model structural representation.
Fig. 2 is the respiratory organ structure sketch map.
As shown in Figure 1: dustproof jar (2)---air pump (3)---battery case (4)---control valve (5)---flexible pipe (6)---face shield (the 7)--respiratory organ of (1) filter poison.Wherein, the filter poison adopts active carbon or molecular sieve as filtrate for anti-jar, and dose aerated plastics, air pump can adopt the micro-blade pump in the existing structure, is driven by micromotor, power can use accumulator, also can use aneroid battery, respiratory organ is arranged in the face shield, and the dustproof jar of filter poison, battery case, micro air pump and control valve four parts are packaged in the box body chamber of a global formation, lie between waist, make it possess advantage easy to use.
As shown in Figure 2: (8) are the respiratory organ base, and its top is the hollow bowl shaped structure, and respiratory organ chamber (9) are the hollow bowl shaped structure that coincide in base (8) shaped upper part, form cavity with ball pad grain (10) supporting between the two, and (11) are hose coupling.
Extraneous air is filtered malicious dedusting by filter poison dustproof jar (1), air pump is with the pure air supercharging, enter the interior respiratory organ (7) of face shield (6) through control valve (4), flexible pipe (5), a positive pressure air part from ejection all around, forms the air-flow shielding along cavity, stops the air of OFP directly to enter operative employee's mouth, nose, a part mildly sprays by the hole, garden, center of respiratory organ chamber (9), for the usefulness of operative employee's breathing, can use control valve that air mass flow is regulated, comfortable to ensure respiration.
The discomfort that the operative employee breathes cold air when considering to work winter can be twined the multilamellar resistance wire in the pump chamber of air pump, in order to filter only, air heat after the supercharging.
This structure is comparatively simple, has that volume is little, weight is light, portable advantage.
This structure can be used for other military, civilian gas masks.
Claims (3)
1, a kind of portable manual arc welding gas defence dust mask, mainly forms by face shield (6), respiratory organ (7), filter poison dustproof jar (1), it is characterized in that being provided with to filter micro air pump (2) that air after dustproof jar of (1) processing of poison carries out supercharging, filter malicious dust excluder (1), micro air pump (2), battery case, control valve (4) be packaged in the box body chamber of a global formation.
2, portable manual arc welding gas defence dust mask according to claim 1 is characterized in that respiratory organ (7) is arranged in the face shield (6), forms cavity by ball pad grain supporting between respiratory organ base (8) and the respiratory organ (9).
3, portable manual arc welding gas defence dust mask according to claim 1 and 2 is characterized in that can be used in other military, civilian gas defence dust mask.
