Detailed Description

The following describes the embodiments of the present utility model in further detail with reference to the drawings.

The utility model provides by fig. 1 to 6, including opening barrel 1 up, barrel 1 left side downside intercommunication has L shape pipe 2, can dismantle in the L shape pipe 2 and be connected with connecting pipe 3, connecting pipe 3 free end can communicate with the breathing machine, barrel 1 upper end can be dismantled and be connected with cover 4, cover 4 upper end is equipped with alarm 5 and travel switch 6, sliding connection has the depression bar 7 of falling L shape on the cover 4, the depression bar 7 lower extreme is equipped with the floater 8 that can insert in the barrel 1, the depression bar 7 upper end runs through cover 4 and its lower step face can be contacted with travel switch 6, the lower step face of depression bar 7 is connected with cover 4 through the extension spring, the through-hole that link up from top to bottom has been seted up on the cover 4, dismantle respectively in the through-hole and be connected with outlet duct 9, outlet duct 9 free ends can communicate with the breathing mask.

In order to detachably connect the connecting tube 3 with the L-shaped tube 2, the connecting tube 3 may be inserted into the L-shaped tube 2 and may be interference fit with the L-shaped tube 2.

In order to make barrel cover 4 and barrel 1 detachable connection, barrel 1 in the upside be equipped with opening casing 10 forward, barrel cover 4 shape is big-end-up's boss shape, barrel cover 4 lower extreme can insert in the barrel 1, is equipped with the inserted link 11 of falling L shape on the barrel cover 4, the inserted link 11 rear end can insert in casing 10 and can with casing 10 interference fit.

In order to detachably connect the air outlet pipe 9 with the through hole, the air outlet pipe 9 can be inserted into the through hole and can be in interference fit with the through hole.

In order to facilitate the observation of the height of the liquid level in the cylinder 1, the front end of the pressure lever 7 is provided with scale marks 12.

In order to achieve better use effect, the L-shaped pipe 2 is higher than the barrel 1 in height, a through hole is formed in the barrel cover 4, and a plug 13 is in interference fit in the hole.

When the device is used, the initial state is that water is filled in the cylinder body 1, the inserted link 11 is inserted into the shell 10, the pressure lever 7 is separated from the travel switch 6, the lower end of the connecting pipe 3 is inserted into the L-shaped pipe 2, the lower end of the air outlet pipe 9 is inserted into the through hole, when oxygen is required to be humidified, the free end of the connecting pipe 3 is connected with a breathing machine, the air outlet pipe 9 is connected with a breathing mask, the alarm 5 is turned on, and the breathing machine is started;

after the breathing machine is started, a power switch is turned on, oxygen enters the barrel 1 through the connecting pipe 3, the L-shaped pipe 2 and water, and oxygen enters the breathing mask through the through hole and the air outlet pipe 9 after being wetted, and as the oxygen can enter the barrel 1 through the water, the oxygen can be fully wetted by the water, so that the phenomenon that the flow rate of the oxygen is too high or the water vapor is too low to be fully wetted is avoided;

as the oxygen is continuously wetted, the oxygen continuously takes away the moisture in the cylinder body 1, the water level in the cylinder body 1 is gradually reduced, the pressure lever 7 drives the floating ball 8 to move downwards under the action of the tension spring until the lower surface of the floating ball 8 is inserted into water, as the water level in the cylinder body 1 is reduced, the pressure lever 7 continuously moves downwards, the corresponding scale mark 12 value on the pressure lever 7 is continuously reduced until the travel switch 6 is extruded and extruded, the circuit formed by the alarm 5 and the travel switch 6 is communicated, the alarm 5 gives an alarm, and medical staff is reminded of water injection into the cylinder body 1;
