Description

Technical Field

[0001] This utility model relates to the field of humidification and oxygen supply terminal technology, and in particular to a humidification and oxygen supply machine. Background Technology

[0002] Existing oxygen supply terminals generally only provide oxygen. While some devices include humidification, their use is limited. These devices typically require users to manually add water to the tank. Others attempt to connect to tap water, but impurities in tap water and large pressure fluctuations can make it difficult to completely close the inlet valve, posing a risk of leakage. Furthermore, calcium and magnesium ions in tap water can easily form scale inside the device, affecting the lifespan and performance of the atomizing head. Existing oxygen supply terminals also suffer from the problem of inadequate water and electricity separation; the water and power supply systems are not effectively isolated, posing safety hazards such as leaks and electrical shocks. Another design concern is the lack of complete isolation between the oxygen concentration detection system and the oxygen delivery channel. If oxygen leaks at the delivery connector, it may interfere with oxygen concentration detection, leading to misjudgments. Finally, existing oxygen supply terminals lack an auxiliary air supply mechanism, resulting in limited oxygen delivery range. Utility Model Content

[0009] Furthermore, the water level control device includes a float device or a solenoid valve control component, which is installed inside the water tank; the water inlet of the water level control device is connected to the water outlet of the leakage protection device or the water pretreatment device.

The water inlet is connected to the water outlet of the filter device; or the water inlet is connected to the water outlet of the pressure reducing device. When the water level control device fails, the water in the water tank exceeds the specified water level. Water flows out from the overflow port of the water tank and into the drainage channel of the base and the front shell, flowing to the water absorption assembly in the leakage protection device. The sponge in the water absorption assembly absorbs water and expands, and the spring assembly springs up, cutting off the water inlet and outlet passage of the leakage protection device.

[0016] Beneficial effects:

[0017] This invention solves the problem that existing indoor oxygen supply units generally only have a single function of oxygen supply, or although some have a humidification function, they cannot continuously add water or leak water. By setting up a humidification system, an oxygen supply system and a controller unit in the unit body, the control unit can control the humidification system and the oxygen supply system individually or simultaneously.

Auxiliary air supply mechanisms are installed inside the mist outlet and oxygen outlet to deliver mist and oxygen further. Attached Figure Description

[0031] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] As attached Figure 1 To the attached Figure 3 The embodiment shown provides a humidification and oxygen supply machine, including a body 10, an oxygen supply system 20, a humidification system 30, and a water circuit control system 40.

[0036] The unit 10 has a first mounting position 11 and a second mounting position 12 arranged sequentially in a vertical or horizontal direction. The unit 10 also includes a mist outlet 13, an oxygen outlet 14, a base drainage channel 15, an external pipe channel 16, and an oxygen silencing chamber 17. An oxygen supply system 20 is located at the first mounting position 11, and a humidification system 30 is located at the second mounting position 12. It can be seen that the humidification system 30 and the oxygen supply system 20 do not interfere with each other. The oxygen supply system 20 is located above or to the side of the humidification system 30, effectively isolating the water tank of the humidification system 30, achieving a water-electricity separation effect. The humidification system 30 is equipped with a water circuit control system 40 for automatically supplying water to the humidification system 30. The water circuit control system 40 includes a water pretreatment device 41 and a water circuit control device 42. The water pretreatment device 41 includes a pressure reducing device 411 and a filter device 412. The water pretreatment device 41 is located outside the unit 10, and the water level control device 42 is located inside the unit 10. The water level control device 42 includes a leakage protection device 421, an elbow 422, a float device 423, an overflow device 424, and a drainage device 425. The leakage protection device 421 is located in the base drainage channel 15, the drainage device 425 is located at the bottom of the machine body, the overflow device 424 and the float device 423 are located inside the humidification system 30, and the elbow 422 is used to connect the leakage protection device 421 and the float device 423.

[0037] Understandably, the inlet of the pressure reducing device 411 is connected to an external tap water pipe, which provides a continuous water supply without the need for manual water addition; the outlet of the pressure reducing device 411 is connected to one end of the filter device 412. After the pressure reducing device 411 adjusts the tap water pressure to an appropriate value, the tap water flows into the filter device 412. The filter device 412 filters and purifies the tap water, removing impurities and substances such as calcium and magnesium ions. The purified water then enters the humidification system 30 through the leakage protection device 421, the elbow 422, and the float device 423.

[0038] like Figure 2-7As shown, the humidification system 30 also includes a water tank 31, a fan 32, an air duct 321, an atomizing device 33, a water shortage detection device 34, an atomizing pipeline 35, and a water tank cover 36. The water leakage protection device 421 includes a water inlet 4211, a water outlet 4212, an absorbent sponge 4213, a spring assembly 4214, and a bracket 4215; the water outlet of the filter device 412 is connected to the water inlet 4211 of the water leakage protection device and exits from the water outlet 4212 of the water leakage protection device. The water outlet 4212 of the water leakage protection device is connected to one end of the elbow 422 through the through hole of the body 10. A float device 423 is installed in the water tank and includes a lower rod 4231, a lower rod opening 4232, a float 4233, and a float 4234. When the water tank 31 is empty, the float device 423 is in the open state. The other end of the elbow 422 is connected to the lower rod 4231, and purified water flows into the water tank 31 from the lower rod opening 4232. After the purified water enters the water tank 31, the atomizing device 33 starts to work, generating mist. The mist is blown out from the mist outlet 13 along the atomizing pipe 35 by the air blower 32, humidifying the indoor environment. The mist outlet 13 is equipped with an auxiliary air supply mechanism. The mist outlet 13 is in a slanted shape with a slant angle of 10° to 89°. The auxiliary air supply mechanism can be used to deliver the mist further while preventing water accumulation in the atomizing pipe 35. When the water level in the water tank 31 reaches the designated position, the float 4234 rises with the water level, and the float rod 4233 blocks the drain rod opening 4232. The float device 423 is in the closed state, and the purified water stops entering the humidification system 30. The overflow device 424 includes a water tank overflow port 4241 and a drainage channel 4242. The water tank overflow port 4241 is located on one side of the water tank 31. When the float device 423 fails, the purified water in the water tank 31 exceeds the designated water level, and the purified water flows out from the water tank overflow port 4241, passes through the drainage channel 4242, and flows to the water-absorbing sponge 4213 in the leakage protection device 421. The water-absorbing sponge 4213 absorbs water and expands, and the spring assembly 4214 is pushed open and pops up, blocking the water inlet 4211 of the leakage protection device. The water stops flowing to the leakage protection device 421 and into the humidification system 30, thus avoiding uncontrollable abnormalities such as water leakage and overflow of the whole machine. The bottom of the water tank 31 is provided with a drain hole 311, which is connected to a rubber stopper 425 or a drain pipe 426. When it is necessary to clean the water tank 31 or empty the water in the water tank 31, the rubber stopper 425 is pulled out or the water in the water tank 31 is drained to the outside through the drain pipe.

[0039] The oxygen supply system 20 includes a control valve assembly 21, an oxygen concentration detection system 22, a three-way connector 23, a third control valve 24, and an oxygen delivery pipe 25. The control valve assembly 21 includes a first control valve 211, a second control valve 212, and a first oxygen connection pipe 213. The three-way connector 23 includes a first connector 231, a second connector 232, and a third connector 233. Oxygen is supplied from the outside. The external oxygen delivery pipe 25 runs through an external conduit channel 16, which is a recessed design to conceal the oxygen delivery pipe 25. External oxygen first enters the first control valve 211 through the oxygen delivery pipe 25, then enters the second control valve 212, and then exits from the second control valve 212.

[0040] The first oxygen connector 231 of the three-way connector 23 is connected to the first oxygen connector 213; the second connector 232 is connected to the oxygen silencing chamber 17 via the second oxygen connector 214, introducing oxygen into the oxygen silencing chamber 17. During this process, the oxygen undergoes internal silencing treatment in the oxygen silencing chamber 17 to reduce noise generated during flow. After silencing, the oxygen is then smoothly blown into the air from the oxygen outlet 14, ensuring the quiet operation of the entire oxygen delivery system. An auxiliary air supply mechanism is provided inside the oxygen outlet 14. The oxygen outlet 14 is in a slanted shape with a slant angle of 10° to 89°, which can be used to deliver oxygen further. The third connector 233 is connected to the third control valve 24 via the connector 215, and together with the oxygen inhalation accessories, supplies oxygen to individuals independently. The oxygen concentration detection system 22 is located at the base 15 and has an independent air intake system, separated from the internal oxygen delivery pipelines 21 and 23, to avoid interference from internal oxygen when the connector leaks oxygen.

[0041] The front cover 50 consists of a panel 51 and a panel bracket 52, and is then fixedly connected to the base 15 via the panel bracket 52; the control unit 60 mainly consists of a main control board 61, an operation panel 62 and its inter-board wiring 63, which controls and displays the entire machine.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
