Wearable non-electric air-supply mask device and method of use

Abstract

A wearable non-electric air-supply mask device and its use method, which include an air-supply system, a power system and a respiratory system; the chest drape is worn on the user's shoulders and front chest; The bellows device and the linkage device on the drape seat, the linkage device is connected with the power input end of the bellows device, the bellows device includes the first bellows and the second bellows arranged side by side; the power system includes the swing rod device and the flexible shaft worn on the lower limbs, The shaft is connected to the linkage device, and the swing rod device transmits the pulling force generated by the limb movement to the linkage device through the flexible shaft, driving the bellows device to supply air; the respiratory system includes an air supply pipe and a mask, and one end of the air supply pipe is connected to the air outlet of the bellows device. One end is connected with the mask worn on the face for air supply. The device integrates the bellows device on the chest, and the swing rod device is integrated on the legs, which transmits pulling force by swinging while walking, and alternately pulls the bellows to supply air and purify air through the principle of lever movement.

Description

technical field [0001] The invention belongs to the field of non-electric air-supply masks, and relates to a wearable non-electric air-supply mask device and a use method. Background technique [0002] Masks are widely used in daily life, but there are many problems with ordinary masks: ordinary masks have breathing resistance, which reduces the smoothness of breathing; the breath exhaled by the wearer contains moisture, which cannot be completely discharged from the outside of the mask; Covered by warm and humid gas, the wearing comfort is reduced. The air supply mask can comprehensively solve the above-mentioned defects of common masks. However, the existing air supply masks use battery-driven air pumps to supply air, and the battery life is limited, and they need to be charged frequently, and the use and maintenance are poor, which limits the popularization and application of battery-powered air supply masks; and effective purification measures are often not adopted.

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a wearable non-electric air-supply mask device and its use method. The device integrates two bellows devices on the chest, and integrates the swing rod device on the waist and legs. The leg swings to transmit the pulling force, and the bellows are alternately pulled to supply air and purify through the principle of lever movement, which solves the problem that the existing technology uses battery drive, which cannot last long, and the mask is too large to affect wearing. It can be hidden in clothes and is easy to carry. Long-lasting features that do not require electricity
