CA 03020350 2018-10-09
A fan 12 is provided at the air inlet 6. The fan 12 continuously sends the
clean air source into
the breathing chamber 1 to further reduce the inspiratory resistance, and is
especially suitable for
people with insufficient lung capacity. On the other hand, since the fan 12
continuously pumps
fresh air, a negative pressure difference is generated in the breathing
chamber 1, making it
difficult for the outside air to be sucked from the gap around the breathing
chamber 1, and
preventing the unfiltered air from entering into the breathing chamber 1.
On the outer side wall of the purifying chamber 4, a plurality of air guiding
grooves 13
communicating with the air inlet 6 are provided. The air guiding grooves 13

extending into the breathing
chamber 1 and engaged with a second fixing sleeve 22, and a unidirectional air
outlet valve piece
23 is disposed at a portion which locates in the inner part of the air outlet
chamber 2 and
connects the air outlet chamber 2 and the air outlet passage 21.
The air purifying negative oxygen ion generating device comprises the negative
oxygen ion
emitting head 3 extending into the purifying chamber 4, and a high voltage
package 24 connected
to the negative oxygen ion emitting head 3.
The negative oxygen ion emitting head 3 comprises a fiber bundle of a micron
order, the

connected to the high voltage package through the wire. With the negative
oxygen ion emitting
6

CA 03020350 2018-10-09
head 3 of the above structure, the negative oxygen ion yield can be greatly
improved and the
ozone concentration can be greatly reduced.
The air inlet device and the air outlet chamber 2 are detachably disposed on
the breathing
chamber 1 through Velcro. The air inlet device and the air outlet chamber 2
and the breathing
chamber 1 are detachable, which facilitates the replacement and cleaning of
the breathing

The battery 5 is disposed in the air outlet chamber 2, and may of course be
disposed at other
suitable positions.
Pressing the switch button 15, the air purifying negative oxygen ion
generating device works.
The air is filtered through the filter layer and enters into the purifying
chamber 4, and the
generated negative oxygen ions purify and sterilize the air, and the fresh air
after sterilization and
purification passes through the intake passage 18 and the one-way air inlet
valve piece 20 and
then enters the breathing chamber 1; and the one-way inlet valve piece 20 is
opened when the
person inhales, and is closed when the person exhales. The effect of natural
oxygen bar is
generated between the breathing chamber 1 and the wearer's face, so that the
wearer can breathe
clean fresh air rich in negative oxygen ions, can sterilize, be anti-virus,
improve body immunity,
and have good health effects. When the person exhales, the one-way air outlet
valve piece 23 is
opened, and the generated exhaust gas enters the air outlet chamber 2 through
the air outlet
passage 21 and the one-way air outlet valve piece 23, thereby being discharged
into the outside,
the exhaust gas is not retained, and the fan 12 can be opened as needed.
The above is only the preferred embodiment of the present invention, and is
not intended to
