Prevent remaining dive full face guard of carbon dioxide

Technical Field

The utility model relates to a mask articles for use technical field, concretely relates to can prevent lens fogging and prevent remaining dive whole face guard of carbon dioxide.

Background

The diving mask generally comprises a face shell, a silica gel face cover, an outer frame, a breathing tube, a head band and the like, wherein the face shell is provided with a lens, the breathing tube is fixed on the face shell, a visual field cavity and a breathing cavity are arranged in the face shell, and the breathing tube is communicated with the breathing cavity. Adopt full face guard breathing mode can provide an independent space, hug closely diver's face through the face guard, diver's mouth nose can freely breathe in this independent space to can provide expiration and inspiratory channel, thereby can improve the travelling comfort of breathing under water. However, the existing diving full mask is easy to accumulate carbon dioxide in the full mask due to the factors of long exhaust stroke and the like, and the inner surface of the mirror surface generates fog, so that potential safety hazards are easy to generate. Therefore, a diving full mask capable of reducing carbon dioxide accumulation is invented, for example, an antifogging diving full mask disclosed in patent CN201721017711.5, the mask can shorten the exhaust stroke through the design of a single pipeline, can discharge carbon dioxide and dirty air out of the full mask more quickly, and greatly reduces the accumulation of carbon dioxide in the full mask, thereby reducing the generation of fog. However, although this solution does provide an improvement in reducing the accumulation of carbon dioxide over conventional masks, the exhaust passage is still long, carbon dioxide remains in the exhaust passage to a large extent, and carbon dioxide is inhaled from the exhaust passage during inhalation, thus posing a safety risk. In addition, the upper end and the lower end of the headband are generally connected and fixed on the outer frame of the existing mask, and the headband is easy to lose due to the fact that no place is fixed after being detached, and the problem that the existing headband is inconvenient to operate when tightness is adjusted is solved.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model adopts the following technical scheme: a diving full face mask for preventing carbon dioxide residue comprises a face shell provided with lenses and a face sleeve with sealing function, wherein the face sleeve is arranged inside the face shell to be combined with the face; the inside position of aiming at the mouth nose that aims at the face-piece has the respiratory cavity, and the position of aiming at eyes has the field of vision chamber, separates each other between field of vision chamber and the respiratory cavity, and the respiratory cavity makes air can one-way entering respiratory cavity through one-way admission valve intercommunication with the field of vision chamber, and the field of vision chamber communicates its characterized in that with the respiratory tube: an exhaust channel is arranged at the edge of the face shell, and a one-way exhaust valve is arranged between the exhaust channel and the breathing cavity so as to form an exhaust structure capable of discharging air from the breathing cavity into the exhaust channel in one way; a waterproof exhaust valve is arranged between the exhaust channel and the outside, the waterproof exhaust valve is arranged at the edge of the face shell, and the breathing cavity is made to form a structure capable of exhausting outwards through the waterproof exhaust valve, the exhaust channel and the one-way exhaust valve.

Furthermore, the exhaust channel comprises exhaust grooves which surround the lower part and two sides of the breathing cavity, the whole exhaust groove is completely embedded in the edge of the face shell, and the exhaust groove is opened towards the back; the edge of the face sleeve is provided with a cover edge which protrudes outwards at the position corresponding to the exhaust groove, and after the face sleeve is combined and fixed with the face shell, the opening of the exhaust groove is sealed by the cover edge to form a complete exhaust channel.

Furthermore, the positions close to the tail ends of the two sides of the exhaust groove are respectively provided with a waterproof exhaust valve, the tail end of the exhaust groove is provided with a partition sheet, and the tail end of the exhaust groove is partitioned by the partition sheet to form a sealing structure.

Furthermore, two one-way exhaust valves are arranged at the positions of the lower part of the breathing cavity, which are opposite to the nose, and the two one-way exhaust valves are respectively communicated with the exhaust channel. The inhaled air enters the visual field cavity through the breathing tube and then enters the breathing cavity through the one-way air inlet valve for breathing; the expired air passes through one-way exhaust valve and gets into exhaust passage, flows to waterproof exhaust valve back discharge face guard outside, and remains the air that contains carbon dioxide in exhaust passage then can not flow back to the breathing chamber owing to one-way exhaust valve's the blockking to can really realize reducing the effect of breathing intracavity residual carbon dioxide.

Furthermore, the lower end of the head band is divided into two branches which are respectively connected and fixed with the fixing ears on the outer frame; the lower part of the respiratory tube is fixed with a bandage, and the upper end of the head band is connected and fixed with the bandage. The headband is normally secured by a strap and therefore is not easily dislodged or lost.

Furthermore, a buckle head is arranged on the binding belt, and the upper end of the head belt penetrates through the buckle head to realize fastening and fixing.

Further, the position that is close to the ribbon on the respiratory tube still is provided with the ear of buckleing, the afterbody of bandeau is provided with first spacing head and second spacing head, separates a section distance between the two, and the bandeau upper end that does not bifurcate passes in proper order and detains the ear to block first spacing head by detaining the ear, block the second spacing head by detaining the head to form the adjustable fixed knot structure of bandeau. The tightness of the headband needs to be adjusted by pulling the headband upwards or downwards, and the upper end of the headband is not divided into two parts, so that the adjustment is more convenient.

The one-way exhaust valve is arranged between the breathing cavity and the exhaust groove in the mask, after the exhaled air enters the exhaust groove through the one-way exhaust valve, although a part of carbon dioxide can inevitably remain in the exhaust groove, the remaining carbon dioxide can not flow back into the breathing cavity due to the blocking of the one-way exhaust valve, so that the problem of carbon dioxide backflow of the existing mask is solved, the safety is improved, and the anti-fog effect is further improved; in addition, through set up the bundle on the respiratory tube and bring fixed bandeau, the bandeau upper end does not need the branch, directly penetrates the ribbon and can play normal fixed bandeau effect, can also conveniently link together respiratory tube and full face mask main part simultaneously simply, prevents that respiratory tube from droing or losing to also make the fixed knot of bandeau construct simpler, the bandeau elasticity is adjusted more conveniently.
