Abstract
The utility model discloses a telescopic close type breathing mask which is characterized in that a filter box is arranged between a mask body and an air bag housing; one end of the filter box is connected with the mask body to form an integral structure and the other end of the filter box is movably connected with the air bag housing in the plug-in joint way, so as to facilitate the assembly; and a silicone rubber filler is arranged inside the filter box and is used for processing carbon dioxide in the closed type breathing mask, which is exhaled by a human being, so as to control the total concentration of carbon dioxide in the air bag, prevent carbon dioxide poisoning during the use process and improve the safety of the product. The entire structure of the product is reasonable; and the mask body fits well with the user's face, is convenient to wear and adapts to emergency handling. With the optimal combination of design structure, the manufacturing cost of the product is reduced while the functionality of the product is effectively improved, thereby improving the market competitiveness of the product. Compared with the prior art, the telescopic close type breathing mask is superior in substantial features and remarkable progress.

Technical field:
The utility model relates to the technical field of emergency relief equipment, a kind of specifically telescopic closed breathing mask, particularly its mechanical connecting structure.
Background technology:
Documents, the patent No.: ZL94213314.5, patentee: Han Han, the applying date: 1994.06.07, this case discloses a kind of " fire prevention escape oxygen mask ", it is characterized in that said face shield is made up of a head-shield and a solid oxygen generator that is enclosed within human body head, said head-shield includes the photoscope corresponding to human body eyes position, corresponding to the human body mouth, the respirator of nose position and tightly be enclosed within the brain cover of human body back brain, position corresponding to the human body bridge of the nose between photoscope and the respirator has one with the two sealing strip that separates, the elasticity band of tying tight is arranged in the bottom of head-shield, said solid oxygen generator is a satchel, in adorn an oxygen-making agent and close and a reactant bag, the oral pore of giving vent to anger is arranged on the solid oxygen generator, oxygen-making agent closes with reactant bag phase-contact surface and has a few row's apertures, and solid oxygen generator is placed on the respirator place in the head-shield.
By being not difficult to find out in the above-mentioned documents, there is defective on traditional closed oxygen breathing mask structure, wearing mode is unreasonable, be not easy under the burst emergency, use and wear, and be not provided with the gas concentration lwevel control structure in traditional oxygen breathing mask, the accident of carbon dioxide poisoning in use takes place easily, moreover, traditional closed oxygen breathing mask costs an arm and a leg, and is unfavorable for penetration and promotion.
The defective of comprehensive above-mentioned technology is so still need existing closed oxygen breathing mask structure is further improved.
The utility model content:
The purpose of this utility model is to provide a kind of telescopic closed breathing mask, it adopts the filter cartridge structure, filter cartridge and air bag shell adopt the chucking mode to flexibly connect, easy to assembly, silica gel filler in the filter cartridge is used for handling the carbon dioxide that circulates and breathe out this sealing breathing mask people, with the carbon dioxide accumulative total concentration in the control air bag, prevent carbon dioxide poisoning in use, overcome the shortcoming and defect that exists in the prior art.
To achieve these goals, the technical solution of the utility model is: a kind of telescopic closed breathing mask, it mainly comprises mask body and air bag shell, be provided with the air bag inner bag in the air bag shell, it is characterized in that: be provided with filter cartridge between described mask body and the air bag shell, one end of filter cartridge and the mask body structure that links into an integrated entity, the other end of filter cartridge and air bag shell adopt the chucking mode to flexibly connect.
The utility model discloses a kind of telescopic closed breathing mask, filter cartridge and air bag shell adopt the chucking mode to flexibly connect, easy to assembly, silica gel filler in the filter cartridge, be used for handling the carbon dioxide that circulates and breathe out this sealing breathing mask people, with the carbon dioxide accumulative total concentration in the control air bag, prevent carbon dioxide poisoning in use, improved the safety coefficient of product, fit the fully face design of product reasonable integral structure, mask body, it is convenient to wear, can be adapted to accident, because the optimum organization on the project organization effectively improves under the prerequisite of product functionality, has reduced the manufacturing cost of product, thereby improved the competitiveness of product in market, product has outstanding substantive distinguishing features and marked improvement compared to existing technologies.

The specific embodiment:
With reference to the accompanying drawings, the utility model further is described
The utility model is a kind of telescopic closed breathing mask, it mainly comprises mask body 1 and air bag shell 2, air bag shell 2 is one by cylindrical shell 9 and lid 10 sockets, be provided with air bag inner bag 3 in the air bag shell 2, the air bag inner bag is that an a kind of soft plastic foil of columniform usefulness is made, the air bag shell is the cylindrical shape of a shaped slightly greater than the air bag inner bag, it is different from prior art and is: be provided with filter cartridge 4 between described mask body 1 and the air bag shell 2, filter cartridge 4 is cylindrical shape, one end of filter cartridge 4 and mask body 1 structure that links into an integrated entity, the other end of filter cartridge 4 and air bag shell 2 adopt the chucking modes to flexibly connect.
In the specific implementation, described filter cartridge 4 outer wall places are provided with spacing snap ring 5, and spacing snap ring 5 is integrative-structure with filter cartridge 4, and the cross section of spacing snap ring 5 shape triangular in shape, circular-arc is provided with hollowed-out board 12 in the filter cartridge 4, be provided with filler between the hollowed-out board 12.
In the specific implementation, described air bag shell 2 places are provided with the ring-type draw-in groove 6 that matches with spacing snap ring 5, ring-type draw-in groove 6 inwalls form circular step 7, the height of circular step 7 is 0.2mm, the wall thickness of ring-type draw-in groove 6 is 1mm-1.2mm, spacing snap ring 5 can cooperate chucking with ring-type draw-in groove 6, guarantees closely to engage between air bag shell and the filter cartridge.
