The utility model provides a fall structure 10 falls, this fall structure 10 is used for installing in the cavity 21 of humidifying bottle, and this fall structure 10 of falling includes air duct 100 and air current buffer 200 to the great use noise of current humidifying bottle exists and influences user's use experience's problem, see fig. 1, fig. 2 and fig. 3.

Wherein, the air duct 100 is used for air flow to pass through, and the air duct 100 has an air outlet 110. The air flow buffer 200 is disposed on the air duct 100, and the air flow buffer 200 has a first buffer chamber 300 communicating with the air outlet 110, and the air outlet 110 faces the bottom of the first buffer chamber 300.

Moreover, an air flow channel 310 is formed at the top of the first buffer chamber 300, and the air flow channel 310 is used for communicating the first buffer chamber 300 with the chamber 21. I.e. when the noise reducing structure 10 of the present application is mounted in the cavity 21 of the humidification bottle, the first buffer chamber 300 communicates with the cavity 21 of the humidification bottle through the air flow channel 310.

It should be noted that, when the noise reduction structure 10 of the present application is configured and installed in a humidification bottle, the air duct 100 extends into the cavity of the humidification bottle, the air flow buffer 200 is immersed in the liquid in the cavity, and the air flow channel 310 communicated with the cavity 21 is provided in the first buffer cavity 300 on the air flow buffer 200, so that the liquid in the cavity 21 flows into the first buffer cavity 300 through the air flow channel 310, so that the first buffer cavity 300 is filled with the liquid. The air inlet 120 of the air duct 100 is connected with a corresponding oxygen input bottle, and when in use, the oxygen input bottle inputs an oxygen flow into the air duct 100, and the oxygen flow flows out from the air outlet of the humidifying bottle after being wetted by the humidifying bottle for inhalation by a user.

The noise reduction structure 10 of the present application is configured to set up the air flow buffer 200 on the air duct 100, and set up the first buffer chamber 300 that is connected with the air outlet 110 of the air duct 100 on the air flow buffer 200, simultaneously, make the air outlet 110 of the air duct 100 face the bottom of the first buffer chamber 300, and set up the air flow channel 310 that is connected with the cavity 21 on the top of the first buffer chamber 300, so that when the humidifying bottle with the noise reduction structure 10 is installed to humidify the oxygen air flow, the oxygen air flow enters the air duct 100 and flows out from the air outlet 110 of the air duct 100, the oxygen air flow will flow with a larger flow velocity towards the bottom of the first buffer chamber 300, and because the air flow channel 310 that is connected with the cavity 21 is located at the top of the first buffer chamber 300, the oxygen air flow flows from the bottom of the first buffer chamber 300 to the air flow channel 310 on the top of the first buffer chamber 300.

In the above process, the oxygen gas flow synchronously pushes part of the liquid in the first buffer chamber 300 to flow into the cavity 21 of the humidification bottle from the gas flow channel 310, that is, the oxygen gas flow overcomes the liquid resistance in the first buffer chamber 300 from bottom to top to apply work, so that the oxygen gas flow is converted from a rapid state to a gentle state, and thus, the oxygen gas flow can flow through the cavity 21 of the humidification bottle in a gentle state and be thoroughly wetted by the liquid in the cavity 21, thus, the noise of the oxygen gas flow flowing in the cavity 21 of the humidification bottle 20 can be reduced, and the wetted oxygen gas flow flows out from the gas outlet of the humidification bottle for the user to inhale. Therefore, the noise in the use process of the humidifying bottle can be effectively reduced, and the use experience of a user is improved.

In some embodiments of the present application, referring to fig. 2 and 3, the direction of extension of the airflow channel 310 is disposed to intersect the length direction of the airway tube 100.

Specifically, the air outlet 110 of the air duct 100 is vertically oriented toward the bottom of the first buffer chamber 300, and the air flow channel 310 is vertically oriented toward the air duct 100. That is, the first buffer chamber 300 is a vertical chamber, the air flow channel 310 is a horizontal channel, the air outlet 110 of the air duct 100 is located between the bottom and the top of the first buffer chamber 300, so that after the oxygen air flows out from the air outlet 110 of the air duct 100, the oxygen air flows into the first buffer chamber 300 vertically downwards, flows into the top of the first buffer chamber 300 vertically upwards after being turned in the first buffer chamber 300, and finally flows into the chamber of the humidification bottle along the air flow channel 310 after being turned in the air flow channel 310.

It will be appreciated that in the process that the oxygen gas flows from the air outlet 110 of the air duct 100 into the cavity of the humidification bottle, the oxygen gas flows through the three turns and still overcomes the liquid resistance of the first buffer cavity 300 to do work, when the oxygen gas flows turn and overcomes the liquid resistance of the first buffer cavity 300 to do work, the flow speed of the oxygen gas is always reduced, and the flow speed of the oxygen gas is reduced by a larger extent when the oxygen gas flows turn, so that the oxygen gas flows through the cavity 21 of the humidification bottle in a more gentle state and is comprehensively wetted by the liquid in the cavity 21, the noise of the oxygen gas flowing in the cavity 21 of the humidification bottle 20 is effectively reduced, and the use experience of a user is further improved.

In some embodiments of the present application, referring to fig. 2 and 4, a first seal 700 is disposed between the airflow damper 200 and the airway tube 100.

Specifically, the middle part of the air flow buffer 200 is provided with an internal thread groove, the lower end of the air duct 100 is provided with an external thread matched with the internal thread groove, the air duct 100 is in threaded connection with the middle part of the air flow buffer 200, and the air outlet 110 of the air duct 100 extends into the first buffer cavity 300 of the air flow buffer 200, so that the air duct 100 and the air flow buffer 200 are convenient for a user to assemble, disassemble and replace.

The first sealing ring 700 may be a rubber sealing ring, and the first sealing ring 700 is disposed at a connection position between the air flow buffer 200 and the air duct 100, so as to enhance tightness between the air flow buffer 200 and the air duct 100, avoid leakage of liquid in the first buffer cavity 300 from between the air flow buffer 200 and the air duct 100, and avoid that oxygen air flows out of the air outlet 110 of the air duct 100 and directly enters into a cavity of the humidifying bottle, so that the oxygen air flows out of the air outlet 110 of the air duct 100 can be decelerated and noise reduced in the first buffer cavity 300.

In some embodiments of the present application, referring to fig. 1, 2 and 4, a buffer plate 400 is disposed on an air flow buffer 200, a second buffer cavity 500 communicating with an air flow channel 310 is formed between the buffer plate 400 and the air flow buffer 200, a plurality of ventilation holes are formed on the buffer plate 400, and the second buffer cavity 500 is communicated with the cavity 21 through the ventilation holes.

Specifically, the buffering plate 400 is circular, and the buffering plate 400 is sleeved on the air duct 100 and fixed on the air flow buffer 200. The first buffer chamber 300 and the second buffer chamber 500 are annular chambers, and the axis of the first buffer chamber 300 and the axis of the second buffer chamber 500 are on the same line, i.e. the first buffer chamber 300 and the second buffer chamber 500 are two vertical chambers distributed up and down.

It will be appreciated that, since the second buffer chamber 500 is communicated with the cavity 21 of the humidification bottle through the vent hole, when the noise reduction structure 10 is integrally installed in the cavity of the humidification bottle, the liquid in the cavity will enter the second buffer chamber 500 through the vent hole, so as to fill the whole second buffer chamber 500.

After the oxygen gas flows out of the gas flow channel 310 at the top of the first buffer chamber 300, the oxygen gas flows into the second buffer chamber 500 formed between the buffer plate 400 and the gas flow buffer 200, and then flows vertically upward along the second buffer chamber 500. Because the oxygen gas flow can form bigger bubbles along the second buffer chamber 500 in the process of flowing into the chamber of the humidification bottle, when the oxygen gas flow passes through the buffer plate 400, the buffer plate 400 breaks up the big bubbles into small bubbles, and meanwhile, when the big bubbles pass through the buffer plate 400, the big bubbles can be differentiated into the small bubbles by the vent holes on the buffer plate 400.

Thus, the large bubble oxygen flow can be differentiated into smaller bubbles by the buffer plate 400 to flow into the cavity of the humidifying bottle and be further humidified by the liquid in the cavity of the humidifying bottle, so that the flow speed of the oxygen flow is reduced, and the noise reduction effect is further achieved; moreover, the oxygen gas flow flows out upwards along the cavity of the humidifying bottle in a smaller bubble form, so that splash generated when the oxygen gas flow flows out of the cavity of the humidifying bottle is avoided, namely, the effervescent phenomenon is avoided, and the noise generated in the humidifying treatment process of the oxygen gas flow by the humidifying bottle is further reduced.

In some embodiments of the present application, referring again to fig. 2 and 4, the noise reducing structure 20 of the present application further includes a fastener 800, where the fastener 800 abuts against the damper plate 400 and is screwed with the air flow damper 200 to fasten the damper plate 400 to the air flow damper 200.

Specifically, the upper end of the air flow buffer 200 has a step surface, the buffer plate 400 is sleeved on the air duct 100 and is abutted against the step surface, and the fastener 800 is in threaded connection with the air flow buffer 200, so that the buffer plate 400 is pressed against the step surface.

Obviously, through fastener 800 and air current buffer 200 threaded connection's mode, can guarantee the installation stability of slow press board 400, avoid slow press board 400 to appear position offset or dislocation, and then guarantee that the oxygen air current homoenergetic of big bubble is differentiated into less bubble by slow press board 400, guarantee the whole noise reduction effect of structure 20 of making an uproar and the effect that the water proof flower splashes.

In some embodiments of the present application, referring to fig. 2 and 4, the airflow damper 200 includes a first defining case 210 sleeved on the air duct 100 and a second defining case 220 sleeved on the first defining case 210, and the first defining case 210 and the second defining case 220 define a first damper cavity 300.

Specifically, the first limiting case 210 and the second limiting case 220 are each in a cylindrical shape, and the first limiting case 210 and the second limiting case 220 are connected by internal threads, so as to facilitate the installation and the removal of the first limiting case 210 and the second limiting case 220.

In addition, the buffer plate 400 and the first defining case 210 define a second buffer chamber 500, and the air flow channel 310 is opened at a sidewall of the first defining case 210.

Through the above arrangement, the oxygen gas flow flowing out from the gas outlet 110 of the gas guide tube 100 can sequentially flow through the first buffer cavity 300, the gas flow channel 310, the second buffer cavity 500 and the vent hole on the buffer plate 400, and then enter the cavity of the humidification bottle, thereby ensuring the speed reduction and noise reduction effects of the first buffer cavity 300 and the buffer plate 400 on the oxygen gas flow.

In some embodiments of the present application, referring again to fig. 2 and 4, a second seal 600 is disposed between the first and second containment shells 210, 220.

Specifically, the second seal ring 600 is a rubber seal ring provided at a connection position between the first and second defining cases 210 and 220, ensuring sealability between the first and second defining cases 210 and 220.

The bottle body is provided with a cavity 21, the cavity 21 is filled with humidifying liquid, and the noise reduction structure 10 is arranged in the cavity 21.
