The working principle is as follows: when air is circulated, the turbofan 6 filters the air through the airstrainer 8 and draws the air into the air inlet 4, and then the air is sucked into the body through the anti-backflow assembly, and the spit air can pass through the air outlet 5 and then be sent out of the air outlet 5 by the other turbofan 6, and is filtered through the airstrainer 8 before leaving the air outlet.

When a child wears the mask, the position of the mask can be too low, the size of the mask needs to be adjusted, firstly, when the size of the head bow 11 is adjusted, the auxiliary moving block 18 is pulled downwards, the auxiliary moving block 18 moves downwards to drive the movable head beam 12 to move downwards, the movable head beam 12 moves downwards to drive the second sliding moving block 17 to move downwards together, the second sliding moving block 17 moves in the moving groove 15, the second sliding moving block 17 extrudes the second sliding moving block 17 when moving through the first rubber bulge 16, after the second sliding moving block 17 passes through the first rubber bulge 16, an upward force is generated because the movable head beam 12 is pulled by the first return spring 13, and meanwhile, the second sliding moving block 17 is blocked by the first rubber bulge 16 to generate an acting force and a friction force between the first rubber bulge 16 and the second sliding moving block 17, the position of the movable head beam 12 is fixed by multiple forces, just so can, with the ascending lifting of position of gauze mask, the position of mouth nose can be covered to the part of gauze mask when letting child wear, can not make the gauze mask can't cover mouth nose because the position of gauze mask is low excessively, and buffering foam-rubber cushion 14 can cushion the impact force to bow 11 when resumeing the normal position with portable head roof beam 12 because of the elasticity of first reset spring 13 causes.

If the position of gauze mask is too high subsequently, need when the position of needs regulation gauze mask, need fixed block 21 will utilize flexible built-in layer 20 to pull down, and the in-process second rubber of flexible built-in layer 20 downward movement can extrude the friction each other, and when adjusting suitable position, second rubber is protruding 19 can prevent flexible built-in layer 20 because self gravity drops down, and the position of flexible built-in layer 20 will be fixed, fixes the position of gauze mask.

When the protective glasses 7 are required to be retracted into the mask body 1, the protective glasses 7 can be directly pulled downwards, the first sliding fixing block 9 of the protective glasses 7 can move downwards along the first sliding rail 10, and the protective glasses 7 are retracted into the mask body 1.

Position adjustment when the gauze mask is accomplished, need be with gauze mask inlayer 35 downward or rebound when the width of gauze mask needs to be adjusted, gauze mask inlayer 35 removes and can take gauze mask inlayer 35 both sides edge to be equipped with fixture block 41 and move together, when moving suitable width, press down the one end of spring fixture block 31, make the perk of the other end at spring 33 place, go into recess 30 with spring fixture block 31, just so fix the position of fixture block 41, just so fix the position of gauze mask inlayer 35, sealing washer 36 makes the gap before gauze mask body 1 and gauze mask inlayer 35 keep sealed can not pass through the air that carries out filtration circulation in the gauze mask body 1 and reveals.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
