Description

Technical Field

[0001] The present invention relates to the field of oxygen generators, and particularly to a humidifying cup for an oxygen generator. Background Art

[0002] An oxygen generator is a type of machine for producing oxygen, and its principle is to utilize air separation technology. First, air is compressed at high density and then, due to the different condensation points of the components in the air, it is subjected to gas-liquid separation at a certain temperature, and then rectified to separate it into oxygen and nitrogen. Generally, since it is mostly used for oxygen production, people are used to calling it an oxygen generator.

[0003] Since medical oxygen is pure oxygen but also dry oxygen without moisture, unlike natural air which contains a certain amount of moisture, dry oxygen will stimulate the upper respiratory tract of people and cause discomfort. Therefore, when inhaling oxygen, it is necessary to humidify the oxygen first. A humidifying cup is a device for humidifying oxygen. Patent Application No.: CN201820674944.0 discloses a humidifying device and an oxygen generator including the humidifying device, a first humidifying cup for containing a humidifying liquid, the first humidifying cup is connected with an oxygen input pipe and an oxygen output pipe, the oxygen input pipe is connected to the oxygen output port of the oxygen generator, and the oxygen output pipe is connected to the air outlet of the oxygen inhalation pipe; a second humidifying cup for containing a spare humidifying liquid, the second humidifying cup is connected with a liquid replenishing pipe, the bottom side walls of the first humidifying cup and the second humidifying cup are communicated through a pipeline, and a one-way valve is provided on the pipeline; a first sensor is installed at the bottom of the inner wall of the first humidifying cup; the first sensor can automatically monitor whether the liquid level of the humidifying liquid in the first humidifying cup is lower than the allowed minimum water level, and transmit a signal to the control unit, and the control unit automatically controls the one-way valve to open and the voice unit issues a reminder voice for liquid replenishment. However, the water level alarm function of such a humidifying cup is realized through a sensor in cooperation with a monitoring unit, a control unit, etc., which not only has a complex structure but also a high cost and is not easy to control.

[0004] The present invention is studied and proposed in view of the deficiencies of the prior art. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide a humidifying cup for an oxygen generator.

[0006] The present invention can be realized by the following technical solutions:

[0007] The present invention discloses a humidifying cup for an oxygen generator, which comprises a bottle body and a bottle cap. An air inlet pipe and an air outlet pipe are respectively fixed on the bottle cap. The air inlet pipe is connected to an extension pipe inside the bottle cap. A water level pipe is also fixed on the bottle cap. One end of the water level pipe is arranged inside the bottle body, and the bottom of the extension pipe is arranged above the end of the water level pipe. The other end of the water level pipe is fixed with a variable-diameter pipe, and the end of the variable-diameter pipe is connected with a whistle through a connecting pipe. An air outlet hole is arranged on the whistle. After water is added into the bottle body, the oxygen separated by the oxygen generator enters the bottle body through the air inlet pipe, the oxygen is discharged from the bottom of the extension pipe, and the oxygen is discharged from the water and humidified and then discharged for use through the air outlet pipe. The liquid level of the water in the bottle body gradually decreases. When the water surface is lower than the bottom of the water level pipe, the oxygen enters the water level pipe from the bottom of the water level pipe and then enters the whistle through the connecting pipe. Part of the gas forms an air flow and is discharged from the air outlet hole, and the other part of the gas flows through the inner surface of the whistle and is discharged from the air outlet hole again. The two gas flows collide, resulting in the air flow being disordered and vibrating to emit a sound, reminding the user that the water volume is insufficient and water needs to be added.

[0008] Preferably, the bottle body is threadedly connected to the bottle cap.

[0009] Preferably, a spherical ball is further arranged inside the whistle. The air flow inside the whistle pushes the spherical ball to roll inside the whistle, further disordering the air flow and causing the air flow to collide and vibrate to emit a sound.

[0010] Preferably, a pressure relief pipe is also fixed on the bottle cap. A pressure relief air pipe is fixed on the pressure relief pipe inside the bottle cap. The pressure relief pipe is also connected to the connecting pipe through an exhaust pipe above. A sealing plug is arranged inside the pressure relief pipe. A spring is arranged inside the pressure relief pipe above the sealing plug. Air permeation holes penetrating through the sealing plug are evenly arranged on the sealing plug at the position of the pressure relief air pipe. When the humidified oxygen cannot be discharged for use through the air outlet pipe, the air pressure inside the bottle body gradually increases. The air pressure pushes the sealing plug to separate from the pressure relief air pipe, and the air flow reaches the whistle position through the air permeation holes, and the whistle emits a sound, which can effectively remind the user to check the device and avoid damage to the device.

[0011] The present invention has the following advantages compared with the existing technology:

[0012] When the water surface is lower than the bottom of the water level pipe, the oxygen enters the water level pipe from the bottom of the water level pipe and then enters the whistle through the connecting pipe. Part of the gas forms an air flow and is discharged from the air outlet hole, and the other part of the gas flows through the inner surface of the whistle and is discharged from the air outlet hole again. The two gas flows collide, resulting in the air flow being disordered and vibrating to emit a sound, reminding the user that the water volume is insufficient and water needs to be added.

[0019] The following will describe in detail the embodiments of the present invention with reference to the accompanying drawings:

[0020] Embodiment 1:

[0021] As Figures 1 to 4 shown, this embodiment discloses a humidifying cup for an oxygen generator, which includes a bottle body 1 and a bottle cap 2. An air inlet pipe 4 and an air outlet pipe 3 are respectively fixed on the bottle cap 2. The air inlet pipe 4 is connected to an extension pipe 5 inside the bottle cap 2. A water level pipe 6 is also fixed on the bottle cap 2. One end of the water level pipe 6 is arranged inside the bottle body 1, and the bottom of the extension pipe 5 is arranged above the end of the water level pipe 6. The other end of the water level pipe 6 is fixed with a reducing pipe 7. The end of the reducing pipe 7 is connected to a whistle 9 through a connecting pipe 8, and an air outlet hole 10 is arranged on the whistle 9. After adding water into the bottle body 1, the oxygen separated by the oxygen generator enters the bottle body 1 through the air inlet pipe 4, the oxygen is discharged from the bottom of the extension pipe 5, and the oxygen is discharged after being humidified from the water and is discharged for use through the air outlet pipe 3. The liquid level of the water in the bottle body 1 gradually decreases. When the water surface is lower than the bottom of the water level pipe 6, the oxygen enters the water level pipe 6 from the bottom of the water level pipe 6 and then enters the whistle 9 through the connecting pipe 8. Part of the gas forms an air flow and is discharged from the air outlet hole 10, and the other part of the gas flows through the inner surface of the whistle 9 and is discharged from the air outlet hole 10 again. The two air flows collide, resulting in a disordered vibration of the air flow and generating a sound, reminding the user that the water volume is insufficient and water needs to be added.

[0022] Among them, the bottle body 1 is threadedly connected to the bottle cap 2.

[0023] Among them, a spherical ball 11 is also arranged inside the whistle 9. The air flow inside the whistle 9 pushes the spherical ball 11 to roll inside the whistle 9, further disordering the air flow and causing the air flow to collide and vibrate to generate a sound.

[0024] Embodiment 2:

[0025] This embodiment discloses a humidifying cup for an oxygen generator. On the basis of the structure and principle of Embodiment 1, a pressure relief pipe 12 is further fixed on the bottle cap 2 of this embodiment. A gas discharge pipe 13 is further fixed on the pressure relief pipe 12 inside the bottle cap 2. The upper part of the pressure relief pipe 12 is also connected to the connecting pipe 8 through an exhaust pipe 17. A sealing plug 14 is further arranged inside the pressure relief pipe 12. A spring 15 is arranged inside the pressure relief pipe 12 above the sealing plug 14. The sealing plug 14 at the position of the gas discharge pipe 13 is also evenly provided with ventilation holes 16 penetrating through the sealing plug 14. When the humidified oxygen cannot be discharged through the air outlet pipe 3 for use, the air pressure inside the bottle body 1 gradually increases. The air pressure pushes the sealing plug 14 to separate from the gas discharge pipe 13. The air flow reaches the position of the whistle 9 through the ventilation holes 16, and the whistle 9 makes a sound, which can effectively remind the user to check the device and avoid damage to the device.

[0026] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, various changes, modifications, substitutions and variations can be made to these embodiments, and these changes, modifications, substitutions and variations should also be regarded as the protection scope of the present invention.
