Worn powerless air supply mask device and application method

Abstract

The invention discloses a worn powerless air supply mask device and an application method. The device comprises an air supply system, a power system and a breathing system; a pectoral base is worn atshoulder parts and forebreasts of users; the air supply system comprises an air box device and a linkage device integrated on the pectoral base at the forebreasts of the users; the linkage device is connected with a power input end of the air box device; the air box device comprises a first air box and a second air box arranged side by side; the power system comprises a swing rod device and a softshaft worn on lower limbs; the soft shaft is connected with the linkage device; the swing rod device conveys tension generated by a limb motion to the linkage device by the soft shaft to drive the air box device to supply air; the breathing system comprises an air supply pipe and a mask; and one end of the air supply pipe is connected with an air outlet of the air box device, and the other end isconnected with the mask worn on faces for air supply. In the device, the air box device is integrated on the forebreasts, and the swing rod device is integrated on the legs; the tension is transferred by using swing during walking; and the air boxes are alternately pulled through a lever motion principle for air supply and purification.

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
