[0002] Air negative oxygen ions, also known as "air vitamins", are an essential substance for human healthy life just like sunlight and air. Negative oxygen ions have the functions of strengthening immunity, preventing and recovering from diseases, regulating the internal rhythm, inhibiting aging, and defending against infections. Therefore, negative oxygen ions are widely used in the field of medical devices.

[0003] In the prior art, negative oxygen ion generating devices often use the principle of air excitation to generate negative oxygen ions, that is, high-pressure air is used to impact liquid, thereby generating negative oxygen ions and releasing them into the surrounding air to purify the air and improve people's living environment.

Generally, the input end of the existing ventilator is composed of a mixture of pure oxygen and external air. After filtration, it enters the airway and alveoli.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only one embodiment of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model.

[0032] Please refer to Figures 1 to 9 , the present utility model provides a direct inhalation negative oxygen ion generating device with a ventilator function.

[0033] As Figure 1 shown, the direct inhalation negative oxygen ion generating device with a ventilator function includes a respiratory mask 1 in contact with the face. The end of the respiratory mask 1 is connected to a Y-shaped connecting tube 2. The upper end of the Y-shaped connecting tube 2 penetrates the respiratory mask 1 and communicates with the patient's oral cavity. The lower end of the Y-shaped connecting tube 2 is fixedly connected to the upper ends of an inhalation channel 3 and an exhalation channel 4 respectively.

[0034] An aqua-removing bottle 41, an expiratory pressure sensor 42, an expiratory control valve 43, an expiratory flow sensor 44 and a check valve 45 are respectively installed on the expiratory channel 4. The gas exhaled by the human body sequentially passes through the breathing mask 1, the Y-shaped connecting tube 2, the expiratory channel 4, the aqua-removing bottle 41, the expiratory pressure sensor 42, the expiratory control valve 43, the expiratory flow sensor 44 and the check valve 45 and is discharged into the surrounding environment.

[0035] A negative oxygen ion generating device 5 is installed at the end of the inspiratory channel 3. The negative oxygen ions generated by the negative oxygen ion generating device 5 pass through an overpressure protector 31, an inspiratory flow sensor 32, an inspiratory control valve 33, an inspiratory pressure sensor 34 and a temperature controller 35, enter the Y-shaped connecting tube 2, and are input into the patient's airway and alveoli.

[0036] Further, an oxygen tank 36 and a mixer 37 are also installed at the end of the inspiratory channel 3. The oxygen tank 36 is used to input pure oxygen, and the negative oxygen ion generating device 5 is used to input negative oxygen ions. The mixer 37 mixes external air, pure oxygen and negative oxygen ions to meet the proportional requirements. Specifically, an oxygen valve 361 connected to the oxygen tank 36, an air valve 362 connected to the air, a negative oxygen ion valve 363 connected to the negative oxygen ion generating device 5 and an oxygen content detector 364 for detecting the oxygen content inside the mixer 37 are installed on the mixer 37.

[0037] The opening and closing of the oxygen tank 36 is controlled by the oxygen valve 361, the connection with the external channel is controlled by the air valve 362, the connection with the negative oxygen ion generating device 5 is controlled by the negative oxygen ion valve 363, and the amount of oxygen inside the mixer 37 is fed back by the oxygen content detector 364 so as to timely control the oxygen valve 361 to supplement oxygen.

[0038] The ventilator further includes an electronic control system. The electronic control system is electrically connected to the expiratory pressure sensor 42, the expiratory control valve 43, the expiratory flow sensor 44 and the check valve 45, the overpressure protector 31, the inspiratory flow sensor 32, the inspiratory control valve 33, the inspiratory pressure sensor 34, the temperature controller 35, the oxygen valve 361, the air valve 362, the negative oxygen ion valve 363 and the oxygen content detector 364, collects the data of the above sensors, and controls the opening and closing of the valve body.

[0039] Specifically, the electronic control system controls the opening and closing of the expiratory control valve 43 and the inspiratory control valve 33, thereby dividing the breathing into two-way control, namely: exhaled gas and inhaled gas. It can also control the oxygen valve 361 by collecting the data of the oxygen content detector 364 to supplement or reduce oxygen.

[0040] In this embodiment, as Figure 3As shown, the negative oxygen ion generating device 5 includes an air compressor 52 installed on one side for generating high-speed air flow, a generator 53 and a water bottle 54 installed on the other side; the generator 53 is installed in the upper part, and the water bottle 54 is installed below the generator 53; the generator 53 and the water bottle 54 are independent of each other and can be separated; thus, the water bottle 54 can be conveniently taken out and separated from the generator 53 later.

[0041] Since water circulation is required between the generator 53 and the water bottle 54, the generator 53 and the water bottle 54 still need to be connected by pipes; specifically, a water inlet assembly 55 and a water return assembly 56 are connected between the generator 53 and the water bottle 54, and the water inlet assembly 55 transports the water in the water bottle 54 into the generator 53; the water return assembly 56 returns the water in the generator 53 to the water bottle 54, thereby realizing water circulation, which is beneficial to saving water and reducing the consumption speed of the water in the water bottle 54.

[0042] However, for the convenience of quickly taking out and inserting the water bottle 54, both the water inlet assembly 55 and the water return assembly 56 are pluggable connections with the water bottle 54; the water bottle 54 can be directly and quickly pulled out from the water inlet assembly 55 and the water return assembly 56, and during installation, it can also be quickly inserted and directly fixed. Quick connectors in the prior art can be used to make the insertion and extraction both quick and convenient; further, in this embodiment, the water bottle 54 is pulled out horizontally, and if optimized, it can also be pulled out vertically.

[0043] As Figure 4 shown, the generator 53 is connected to the air compressor 52 through an input air pipe 521, and the high-speed air flow is input into the generator 53, so that a negative pressure is generated inside the generator 53, and the water in the water bottle 54 is directly sucked into the generator 53 through the water inlet assembly 55 and is cut and broken by the high-speed air flow to form negative oxygen ions; the negative oxygen ions are connected to the negative oxygen ion valve 363 through an output pipe 531 on the generator 53.

[0044] Further, a part of the negative oxygen ions are input into the ventilator through the negative oxygen ion valve 363, and another part of the negative oxygen ions are re-condensed into water and flow back to the water bottle 54 through the water return assembly 56.

[0045] As Figure 5 shown, the generator 53 further includes an upper housing 532, the upper housing 532 is cylindrical, and an input air pipe 521 is provided on one side of the upper housing 532, and the input air pipe 521 inputs high-pressure gas into the generator 53; further, the generator 53 further includes a lower housing 534 installed below the upper housing 532, the lower housing 534 is also cylindrical and has a U-shaped cross-section, and the lower housing 534 seals the generator 53 and also places and guides the water inside the generator 53.

[0046] As Figure 5 shown, the water inlet assembly 55 includes a first right-angle pipe 551 inserted into the water bottle 54, a second right-angle pipe 552 installed on the upper part of the upper housing 532, and a first U-shaped connecting pipe 553 for connecting the first right-angle pipe 551 and the second right-angle pipe 552; one end of the first U-shaped connecting pipe 553 is inserted into the first right-angle pipe 551, and the other end is inserted into the second right-angle pipe 552; under the action of negative pressure, the water in the water bottle 54 sequentially passes through the first right-angle pipe 551, the first U-shaped connecting pipe 553, and the second right-angle pipe 552 and enters the generator 53, and flows out vertically downward; further, seals are installed between the first right-angle pipe 551, the first U-shaped connecting pipe 553, and the second right-angle pipe 552 to seal the connection points.

[0047] As Figure 5 shown, the water return assembly 56 includes a first water return interface 561 installed on the lower housing 534, a second water return interface 562 installed on the water bottle 54, and a second U-shaped connecting pipe 563 for connecting the first water return interface 561 and the second water return interface 562; one end of the second U-shaped connecting pipe 563 is inserted into the first water return interface 561, and the other end is inserted into the second water return interface 562; the water in the generator 53 sequentially passes through the first water return interface 561, the second U-shaped connecting pipe 563, and the second water return interface 562 and flows back into the water bottle 54.

[0048] As Figure 5 shown, in order to make the water inlet of the generator 53 and the water return of the water bottle 54 more convenient and smooth, the second water return interface 562 is arranged at the upper part of the water bottle 54, the first right-angle pipe 551 is arranged at the lower part of the water bottle 54, and the second water return interface 562 is higher than the first right-angle pipe 551; there is a certain vertical height difference, which can be clearly seen in Figure 5 ; in this way, the second water return interface 562 can operate smoothly, return the re-condensed water flow back into the water bottle 54, so as to realize the recycling of water and ensure the full utilization of the water resources in the water bottle 54.

[0049] As Figure 8 shown, in order to collect the water in the generator 53 faster, a first inclined plane 535 is provided inside the lower housing 534, the end of the first inclined plane 535 is connected to the first water return interface 561, and the re-condensed water moves downward along the first inclined plane 535 to guide the water into the first water return interface 561 and flow back into the water bottle 54, so as to realize the water return.

[0050] Further, as Figure 6As shown, in order to fully absorb the water resources in the water bottle 54, a groove 543 is provided at the bottom of the water bottle 54. The groove 543 is at the lowest point of the water bottle 54. The first right-angle tube 551 is L-shaped, and its end is vertically inserted into the inside of the groove 543 and is connected to the first U-shaped connecting tube 553 on the side, so that all the water in the water bottle 54 can be sucked dry.

[0051] Furthermore, in order to seal the water bottle 54, a water injection port 549 and a water injection port cap 550 for sealing the water injection port 549 are provided at the top of the water bottle 54; water is added through the water injection port 549, and the water injection port cap 550 blocks or seals the water injection port 549 to prevent water from flowing out of the water injection port 549; furthermore, the water injection port cap 550 is threadedly connected to the water bottle 54 to block or seal the water injection port 549.

[0052] When water needs to be added, the water bottle 54 is horizontally pulled out to take out the independent water bottle 54, the sealing cover body is spirally removed, and then the water injection port rubber plug is vertically pulled out, and water is added through the water injection port 549.

[0053] As Figure 8 shown, a first support plate 571 is installed on the upper housing 532. The first support plate 571 is provided with a first through hole 572. A vertical water inlet pipe 573 connected to the second right-angle tube 552 is installed inside the first through hole 572. Water is vertically output outward inside the vertical water inlet pipe 573. A number of second through holes 579 are also provided on the vertical water inlet pipe 573. The second through holes 579 are communicated with the input air pipe 521. The diameter of the end of the vertical water inlet pipe 573 is smaller than the diameter of the first through hole 572. A high-speed air flow annular outlet 574 is formed between the vertical water inlet pipe 573 and the first through hole 572; the high-speed air flow annular outlet 574 is communicated with the input air pipe 521 through the second through holes 579 to eject high-speed air flow, generating negative pressure at the end of the vertical water inlet pipe 573, so that the water in the water bottle 54 flows downward through the vertical water inlet pipe 573, is cut and broken by the high-speed air flow to form negative oxygen ions. Part of the negative oxygen ions are input into the ventilator through the negative oxygen ion valve 363, and the other part of the negative oxygen ions are re-condensed into water and flow back into the water bottle 54 through the first water return interface 561.

[0054] As Figure 9As shown, a second annular inclined surface 5731 is provided on the side of the vertical water inlet pipe 573. The second annular inclined surface 5731 guides the high-speed air flow into the high-speed air flow annular outlet 574. An upper side of the first through hole 572 is provided with a first annular inclined surface 5721, and an end of the vertical water inlet pipe 573 is provided with an inclined chamfer surface 5732. Before the high-speed air flow enters the high-speed air flow annular outlet 574, it is compressed by the second annular inclined surface 5731 to increase the air flow speed, and the water molecules at the end of the vertical water inlet pipe 573 are inclinedly cut, impacted, and shattered along the first annular inclined surface 5721 and the inclined chamfer surface 5732, so as to fully mix the air flow and the water molecules, generating more negative oxygen ions. This is better than the above-mentioned ordinary annular impact effect and generates more negative oxygen ions.

[0055] As Figure 8 shown, a second support plate 575 for impact noise reduction is installed at a lower part of the first support plate 571. The second support plate 575 can be made of a flexible noise reduction material component, thereby reducing the noise generated by the impact of the high-speed air flow and having a sound insulation effect.

[0056] As Figure 8 shown, an impact filter screen 576 is provided below the second support plate 575. The impact filter screen 576 re-condenses the shattered water mist into water and flows back into the water bottle 54, thereby realizing the recycling of water and ensuring the full utilization of the water resources in the water bottle 54.

[0057] As Figure 8 shown, the generator 53 further includes a sealing cover 581 installed on the upper part of the upper housing 532. The sealing cover 581 is vertically inserted into the upper housing 532 to guide the negative oxygen ions into the output pipe 531. The output pipe 531 is connected to the sealing cover 581 through a universal joint. Among them, the presence of the sealing cover 581 can help prevent substances such as negative oxygen ions or water vapor from escaping from the device and maintain the sealing of the system. The sealing cover 581, the upper housing 532, and the lower housing 534 form a sealed body.

[0058] The sealing cover 581 is further provided with a safety valve 582, and the safety valve 582 is communicated with the output pipe 531. The presence of the safety valve 582 is to release excessive gas when the internal air pressure of the system rises abnormally, so as to avoid damage to the device due to increased air pressure. This is a protection measure to prevent damage to the device or safety hazards caused by excessive pressure.

[0059] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
