Sieve pore 151, sieve pore 151 are used to flow into the outside air progress primary filtration and guidance outside air that enter in ventilation slot 13 logical
The effect of wind groove 13.Outside air enters air intake 21 by ventilation slot 13, and filter 6 is in ventilation slot 13 to the air of entrance
It is filtered, filtered air enters blower 2.
The blower 2 is arranged in helmet shell 1, and blower 2 is fixed in helmet shell 1, and blower 2 is specifically in helmet shell 1
Rear, outlet air end 22 are connected to the inside of mask 3 by discharge pipe 9, and blower 2 uses small-sized radial fan 2, and discharge pipe 9 is
Oblate pipe fitting, discharge pipe 9 are fixed at the inner wall of helmet shell 1, and 9 overall structure of discharge pipe is in and the head of human body is adapted
Arcuate structure, discharge pipe 9 will be sent into mask 3 by the filtered air of blower 2, and the air outlet 91 of discharge pipe 9 is towards face
The inner wall of cover 3, therefore air-flow can be flushed in large area on mask 3, and wearer's breathing is avoided to generate fog on mask 3, and
And mask 3 has the effect of drainage to filtered air, so that the inside of mask 3 forms circulating current, circulating current can band
The steam in mask 3 is walked, so that wearer experiences the nice and cool and breathing smooth of face.
In addition, the air outlet 91 of discharge pipe 9, in oblateness, the shape and 3 upper end cross sectional shape of mask of air outlet 91 are opposite
It answers, when so that filtered air being entered in mask 3 from air outlet 91, rinses area and increase, the air velocity into mask 3
It reduces, so that air can enter mask 3 to homogeneous soft, avoids high-speed flow from directly blowing and beating facial bring uncomfortable.
Flexible surrounding edge 31 is arranged in the edge of the mask 3, and elastic surrounding edge 31 is whole circular in configuration, and elastic surrounding edge 31 is solid
The edge of mask 3 is set calmly, mask 3 is worn on face, elastic surrounding edge 31 is tightly attached to the periphery of face, to guarantee to dress
The fitting effect of mask 3 avoids mask 3 from loosening and improve mask for human body face and extraneous partition effect, elastic surrounding edge 31
On offer several air discharge ducts 32, filtered air is sent into mask 3 by blower 2, and extra air mainly passes through row in mask 3
Air drain 32 is discharged, and the additional air in mask 3 is oriented discharge.
The air outlet 91 of discharge pipe 9 is located at the front of 1 inside of helmet shell, and discharge pipe 9 passes through the upper end of elastic surrounding edge 31, so that
The inside of mask 3 forms top-down circulating current.
The upper end of the helmet shell 1 offers opening 14, and when dressing this helmet, opening 14 allows head to be connected to the external world, is open
14 play purpose that is ventilative, perspiring, and the extra air of 3 inner part of mask is outwardly discharged, in circulating current band from bottom to top
Under dynamic, the air for having part extra can be discharged from the upper end of elastic surrounding edge 31, which brushed human body head from opening
14 are discharged and take away the sweat of human body head, and wearing can also generate feeling of oppression and heat, therefore this helmet for a long time to avoid human body head
Has the advantages that wearing comfort.
The front end of helmet shell 1 is also equipped with headlamp 8, and headlamp 8 is electrically connected battery 4, starts headlamp 8, illumination
Lamp 8 works under dim environment for wearer to front irradiation and provides illumination.
The process of circulation of the air introduced below in the helmet:
Arrow in Fig. 6 represents blower 2 and works the dynamic direction of Airflow, turns on the power switch 7, and battery 4 is to blower 2
Power supply, blower 2 start, and outside air enters ventilation slot 13 by 15 primary filtration of vent flap, the filter 6 in ventilation slot 13
Air is further filtered, filtered air flows to blower 2 by ventilation slot 13, then is flowed in mask 3 by ventilation channel,
Air in mask 3 is discharged by the gap between air discharge duct 32 and mask 3 and human body face, as long as blower 2 continues work
Make, the air in mask 3 can obtain lasting update.
As shown in fig. 6, arrow indicates the dynamic direction of this helmet work Airflow in figure.Use the general flow of this helmet
Are as follows: turn on the power switch 91, blower 3 starts, blower 3 by by extraneous air successively pass through vent flap 15, air intake duct 121,
Blower 3, wind speed sensing device 5 and discharge pipe 8 enter in breathing area, and extraneous air passes through 4 mistake of filter in air intake duct
Filter, blower continue working to maintain barotropic state in breathing area, the additional air in breathing area by air discharge duct 32,
It arranges outwardly in the gap of mask and human body face.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model
