The working principle of the invention is as follows:
in a normal state, as shown in fig. 1-5, condensed water flows into the inclined plane 202 from the through hole 101 and then flows into the two breathing machine branch pipelines below, the condensed water enters the first condensed water collecting cavity 5 and the second condensed water collecting cavity 6 from the condensed water guide pipe 8, the water passing hole 51 and the check passage port 1001 (at the moment, the check side frame 9 and the check side buckle 10 are clamped together), so that the condensed water is collected, the floating ball floats at the moment, and the atomization capillary 19 is completely immersed in the liquid level of the condensed water;
meanwhile, high-speed air/air-oxygen mixture (although the high-speed air/air-oxygen mixture is still very small compared with the gas quantity in the built-in pipe of the breathing machine, the influence on the oxygen content ratio is very small) is introduced into the ventilation manifold 16, the gas in one ventilation branch pipe 17 passes through the conical pipe 18, the gas speed is gradually increased due to the gradual decrease of the inner diameter, the speed is maximum when reaching the top end of the conical pipe 18, the pressure is also reduced, at the moment, condensed water is sucked up by the atomization capillary 19 to strike the stop block 20, so as to form atomized gas, and the atomized gas is flushed into the atomization guide pipe 21 on the ventilation impact of the other ventilation branch pipe 17 (which is arranged in an upward extending way) and then is sent into the built-in pipe 1; the last ventilation branch pipe 17 is arranged to ensure that the pressure intensity in the first condensation water collecting cavity 5 and the second condensation water collecting cavity 6 is always the same as the external pressure intensity, so that the situation that the atomization capillary 19 cannot suck up the condensation water when the first condensation water collecting cavity 5 and the second condensation water collecting cavity 6 are sealed into a sealed cavity due to backflow prevention is avoided;
when the ventilator pipeline is inclined, as shown in fig. 6-8, at this time, the non-return side buckle 10 slides leftwards/rightwards, and when the non-return side buckle 10 slides onto the wall of the first condensation water collecting cavity 5, the buckling surface of the non-return side buckle completely covers the water passing hole 51, and as the non-return channel port 1001 and the water passing hole 51 are staggered, the condensation water backflow channel is closed, so that the backflow preventing function is realized, and at this time, the two elastic adsorption films are adsorbed together (the adsorption force is also flushed under the action of certain gravity of water);
at this time, the floating ball floats, and the atomization capillary 19 is completely immersed in the condensed water level;
meanwhile, high-speed air/air-oxygen mixture (although the high-speed air/air-oxygen mixture is still very small compared with the gas quantity in the built-in pipe of the breathing machine, the influence on the oxygen content ratio is very small) is introduced into the ventilation manifold 16, the gas in one ventilation branch pipe 17 passes through the conical pipe 18, the gas speed is gradually increased due to the gradual decrease of the inner diameter, the speed is maximum when reaching the top end of the conical pipe 18, the pressure is also reduced, at the moment, condensed water is sucked up by the atomization capillary 19 to strike the stop block 20, so as to form atomized gas, and the atomized gas is flushed into the atomization guide pipe 21 on the ventilation impact of the other ventilation branch pipe 17 (which is arranged in an upward extending way) and then is sent into the built-in pipe 1; the last ventilation branch pipe 17 is arranged to ensure that the pressure intensity in the first condensation water collecting cavity 5 and the second condensation water collecting cavity 6 is always the same as the external pressure intensity, so that the situation that the atomization capillary 19 cannot suck up the condensation water when the first condensation water collecting cavity 5 and the second condensation water collecting cavity 6 are sealed into a sealed cavity due to backflow prevention is avoided;
when the ventilator pipeline is inverted for 180 degrees in extreme cases, as shown in fig. 9-11, the balancing weight 11 is pinned on the buckling surface of the buckle 10 at the non-return side and is positioned below the non-return passage port 1001, and the balancing weight 11 is inverted for 180 degrees to be placed to completely cover the non-return passage port 1001, so that a condensate water backflow passage is closed, and a backflow prevention function is realized; it should be noted that, when the ventilator circuit is inverted to a certain angle (less than 180 °) in a more extreme case, the counterweight 11 will also move to completely cover the return passage port 1001 due to the magnetic attraction of the first magnet block 12 and the second magnet block 13;
at this time, the floating ball falls down along with the gravity of the connecting block and floats on the liquid surface in the first condensate collecting cavity 5 along with the liquid surface, and the atomizing capillary 19 is completely immersed in the liquid surface of the condensate;
meanwhile, high-speed air/air-oxygen mixture (although the high-speed air/air-oxygen mixture is still very small compared with the gas quantity in the built-in pipe of the breathing machine, the influence on the oxygen content ratio is very small) is introduced into the ventilation manifold 16, the gas in one ventilation branch pipe 17 passes through the conical pipe 18, the gas speed is gradually increased due to the gradual decrease of the inner diameter, the speed is maximum when reaching the top end of the conical pipe 18, the pressure is also reduced, at the moment, condensed water is sucked up by the atomization capillary 19 to strike the stop block 20, so as to form atomized gas, and the atomized gas is flushed into the atomization guide pipe 21 on the ventilation impact of the other ventilation branch pipe 17 (which is arranged in an upward extending way) and then is sent into the built-in pipe 1; the last ventilation branch pipe 17 is arranged to ensure that the pressure intensity in the first condensation water collecting cavity 5 and the second condensation water collecting cavity 6 is always the same as the external pressure intensity, so that the situation that the atomization capillary 19 cannot suck up the condensation water when the first condensation water collecting cavity 5 and the second condensation water collecting cavity 6 are sealed into a sealed cavity due to backflow prevention is avoided.
The present invention is not limited to the above-mentioned embodiments, and any person skilled in the art, based on the technical solution of the present invention and the inventive concept thereof, can be replaced or changed within the scope of the present invention.
