Document Type and Number:
WIPO Patent Application WO/2020/184993
Kind Code:
A1
Abstract:
The present invention relates to a personal air purifier wherein a device for purifying air is directly connected to a respiratory device worn on the user's face so as to enable the consumer to directly inhale purified air such that same can be utilized in various indoor spaces according to the consumer's needs. More specifically, the present invention relates to a portable personal air purifier comprising: a purifier body shaped such that the user can carry same and configured to purify air by a filter; a ventilation body connected to the purifier body so as to circulate air; and a respiratory device connected to the ventilation body and mounted such that purified air can be inhaled. The purifier body has a filter containing space formed in a casing thereof such that a filter can be inserted therein. The filter containing space is provided in such a structure that a filter can be moved into/out of same in one direction, thereby making it possible to insert/remove a filter body. The respiratory device is configured such that respiration proceeds through a ventilation line for air introduced from the purifier body and a ventilation line for air exhaled from the user, which is separate therefrom, thereby making it possible to inhale purified air and then discharge exhaled air to the outside. In the filter containing space of the casing, a lock device for preventing the contained filter from detaching and an elastic support means for inducing an outward movement of the filter by means of an elastic restoration force, when the lock device disengages, are provided, thereby making it possible to easily move the filter outwards or to insert same. Accordingly, the air purifier can be worn on the user's face only when necessary while carrying same, thereby enabling the user to breathe only purified air. The filter is configured such that the user can easily replace same. The air purifier, in spite of being compact, has a simplified intake/exhaust structure while guaranteeing smooth respiration, thereby accomplishing compactness thereof.
