Summary of the invention
To solve the above-mentioned problems, the utility model provides a kind of smoke helmet of replaceable gas cylinder, it is intended that
A kind of smoke helmet that can replace oxygen cylinder is provided, and oxygen cylinder is easy to carry and replaces.
To achieve the above object, the smoke helmet of replaceable gas cylinder provided by the utility model is achieved in that one kind
The smoke helmet of replaceable gas cylinder, including mask, mask connecting pipe and storage cylinder, the mask and storage cylinder are connected by mask
Adapter tube connection, the mask include rubber fixing belt, safety goggles and mask cover, and it is inverse that air-flow is housed on the mask connecting pipe
Stops and small pneumatic table, the storage cylinder bottle mouth position of the storage cylinder be provided with tooth form be isosceles triangle external screw thread and with even
The internal screw thread for taking over lower end interface matches, and storage cylinder bottle mouth position is equipped with push type air valve.
As further explanation, the mask cover and rubber fixing belt use hot-melt adhesive paste.
As further explanation, the eye protection eye is loaded at the nose support of mask cover, and the mode that is loaded is using molding slide fastener
Connection.
As further explanation, the filter screen as made of fibrous woven is covered on the air-flow check, the air-flow is inverse
The both ends of stops are provided with perforation card slot, and the buckle for air-flow check block is fixed.
As further explanation, the storage cylinder uses cylinder upper end inner concave shape body structure, and in the indent of the cabinet
Storage cylinder bottleneck is equipped at the heart.
Compared with prior art, when fire occur and needing to escape, air accumulator and mask connecting pipe need to only be carried out
It is screwed on, keeps the utility model very easy to use；And oxygen does not need to be produced by chemical reaction, saves significantly
The volume and weight for having saved device keeps the utility model more portable.By using the utility model, can be won for fire rescue
The more time is taken, so highly promoting.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Understand and is fully described by.It is not that this is practical new embodiment described herein a part of the embodiment of only the utility model
The whole embodiments of type.Based on the embodiments of the present invention, those skilled in the art is not making creative work
Under the premise of every other embodiment obtained, fall within the protection scope of the utility model.
It please refers to Fig. 1-5 to show, the utility model is a kind of smoke helmet of replaceable gas cylinder, and it includes have mask 1, face
Cover connecting tube 2 and storage cylinder 3.The connecting tube upper interface 201 and connection that mask 1 and storage cylinder 3 pass through 2 both ends of mask connecting pipe
Lower end interface 205 is managed to be attached；103 front of mask cover is equipped with screw thread mouth, the connecting tube upper interface of mask connecting pipe 2
201 are threadedly coupled with the use of mask cover 103, and it is relatively large in diameter, to guarantee that oxygen more evenly and is slowly transported to
The inside of mask.
In conjunction with Fig. 3, mask 1 is made of rubber fixing belt 101, safety goggles 102 and mask cover 103.The eye protection eye
Mirror 102 is loaded at the nose support of mask cover 103, and the mode that is loaded is using molding slide fastener connection.Mask cover 103 is by silica gel and increasing
Strong polycarbonate is combined, and can have good buffer action, pernicious gas enters human body when fire can be effectively prevent to occur；
101 main material of rubber fixing belt is rubber, with good shrinkage, to facilitate personnel to wear the utility model, rubber
Also there is certain skid resistance, mask is made to be not easy to fall off from head.Mask cover 103 and rubber fixing belt 101 are connected using hot melt
