阅读说明：本技术 伸缩调向式口罩 (Telescopic direction-adjustable mask ) 是由 赵秀卿 于 2020-04-13 设计创作，主要内容包括：该发明涉及一种伸缩调向式口罩。在非典肺炎抗疫中,普通一次性口罩均含有防毒药剂,由此比较安全。其缺点是鼻和口对应的过滤材料区域之间,接触压力和张力比较大,导致呼吸气流产生的湿性及粘性浓度大,出现不良反应。我利用一只医务供氧面罩SIZE型改造,制成伸缩调向式口罩,特别适用于老人和儿童。(The invention relates to a telescopic direction-adjusting mask. In SARS epidemic prevention, the common disposable mask contains anti-virus medicine, so it is safe. The disadvantages are that the contact pressure and tension between the filter material areas corresponding to the nose and the mouth are relatively large, so that the humidity and viscosity concentration generated by respiratory airflow are large, and adverse reactions occur. I utilize a medical oxygen suppliment face guard SIZE type to reform transform, make flexible accent formula gauze mask, be particularly useful for old man and children.)

1. A telescopic mask with adjustable direction is composed of mask shell, movable handle for breathing air flow, unidirectional box for breathing air flow, and tying band. Wherein:

respiratory airflow movable handle, telescopic direction-regulating pipeline]And single-side drum type gas defense box [ H ]₀]Assembled, telescopic and direction-adjustable pipeline (S)]Has the functions of compressing, extending and adjusting direction; half-drum type gas defense box with shield (H)₀]And a filter material [ F ] containing an anti-toxic substance]Composition is carried out;

the expiratory flow one-way box is composed of a shield [ C ]]And a vibration membrane [ C ] containing gas defence₀]And (4) forming.

2. According to claim 1, the diameter, height (length) and diameter of the expiratory flow outlet of each type of respiratory flow inlet pipe are designed in a proportional manner, and the minimum value is 1.6 times. Namely, the diameter of the respiratory airflow delivery port pipeline is 25 mm: 40mm, height (length) 20 mm: 32mm, expiratory flow outlet diameter 20 mm: 32 mm.

3. According to claim 1, [ S ]]The front end of the pipeline is connected with a half-drum type anti-poison box by screw threads [ S ]]End is male end, [ S ]]The tail end of the pipeline is connected with the respiratory airflow port of the mask for insertion, and a thread is left outside the socket port and corresponds to a half-drum type gas defense box [ H ]₀]If not, [ S ]]Half-drum type gas defense box [ H ] for pipeline₀]The thread is screwed into the mask for use.
