In the presence of, thus by controller make Non-return air valve 13 open, two-position two-way solenoid valve 14 be powered so that 11 He of horizontal communication road
Vertical air passage 12 is connected to, while three position four-way electromagnetic valve is powered, and 9 air inlet of the first tracheae, 10 outlet of the second tracheae are then without bar
7 volume of chamber becomes larger, and piston rod 5 moves down, and oxygen filling head 3 is driven to be moved downward to the upper end of Portable oxygen cylinder 16；Oxygen
During gas filling head 3 moves down, oxygen filling head 3 gradually gos deep into the bottle cap cavity of Portable oxygen cylinder 16.
When oxygen filling head 3 compresses Portable oxygen cylinder 16, a pair of of photoelectricity that oxygen filling head 3 blocks lower section at this time is opened
It closes, so that the disconnection of optoelectronic switch, and then controller acts three position four-way electromagnetic valve, the first tracheae 9 and the second tracheae 10
Gas circuit block, guarantee that piston rod 5 is not moved and remain stationary, piston rod 5 avoided to continue to move down and oxygen filling head 3
The case where damaging Portable oxygen cylinder 16 by pressure generation；At the same time, the compressed gas in high-pressure oxygen cylinder 15 passes through Non-return air valve 13
It enters in horizontal communication road 11 and vertical air passage 12, compressed gas is greater than the gas pressure in Portable oxygen cylinder 16 because of pressure
By force, and then from high-pressure oxygen cylinder 15 compressed gas come out enters in Portable oxygen cylinder 16 by vertical air passage 12, into
The filling of row oxygen.
After the completion of the oxygen of Portable oxygen cylinder 16 has been filled with, because oxygen is difficult to continue to fill up, oxygen is deposited in perpendicular
Into air passage 12, and then the air pressure of vertical air passage 12 increases, and informs that controller closes unidirectional gas by pressure sensor
Valve 13, horizontal communication the road 11 so that gas supply of high-pressure oxygen cylinder 15 disconnects, while when two-position two-way solenoid valve 14 acts and perpendicular
Blocked to the connectivity part of air passage 12, control three position four-way electromagnetic valve at the same time and be powered so that 10 air inlet of the second tracheae and the
One tracheae, 9 outlet, 8 inner volume of rod chamber increase, and piston rod 5 moves up, when piston rod 5 drives oxygen filling head 3 to moving up
When moving to the position of top optoelectronic switch, the light of optoelectronic switch is not blocked i.e. overlying photoelectric switch connection, then passes through control
Device processed makes the electromagnetism valve events of 3-position 4-way, and the gas circuit of the first tracheae 9 and the second tracheae 10 blocks, and guarantees that piston rod 5 exists
It is remain stationary after rising to top.
Piston rod 5 drives after oxygen filling head 3 moves upwardly together, convenient for traveller by the portable oxygen for oxygen of substituting the bad for the good
Bottle 16 is removed from fixing seat 17.
It is used together, is realized in highlands to oxygen with Portable oxygen cylinder 16 using present apparatus combination oxygen vending machine
The function that the Portable oxygen cylinder 16 that gas is used up is filled reduces from factory and transports oxygen cylinder bring transportation cost, together
When also avoid explosion present in oxygen cylinder transportational process dangerous situation occur, overcome in the prior art on plateau not
There are problems that the filling device of oxygen.
The device allows Portable oxygen cylinder 16 to repeat to fill oxygen and is repeatedly utilized, on the one hand the trip of reducing
The consumer cost of passerby, on the other hand, the quantity of disposable oxygen cylinder are reduced, and are equivalent to and are played the role of protecting environment.
The present apparatus is realized by oxygen filling head 3, piston type cylinder 2, controller etc. and is filled out automatically to the adding pressure type of oxygen
It fills, does not need individually to employ artificial progress oxygen filling, thus cost is lower, is conducive to the device in scarcely populated plateau
Area popularizes.
