Description

Technical Field

[0001] The invention relates to the technical field of hydrogen and oxygen atomizers, and in particular to a hydrogen conveying and water removing device for a hydrogen and oxygen atomizer. Background Art

[0002] The hydrogen and oxygen nebulizer is a device that can replace, control or change a person's normal physiological breathing, increase lung ventilation, improve respiratory function, reduce respiratory function consumption, and save heart reserve capacity. It is mainly used in hospitals, clinics, homes and other places. It is a vital medical device that can prevent and treat respiratory failure, reduce complications, save and prolong patients' lives. It occupies a very important position in the field of modern medicine.

[0003] The hydrogen and oxygen atomizer forms tiny atomized particles by mixing hydrogen and oxygen for respiratory treatment and other purposes. In the field of hydrogen medicine, hydrogen is considered to have potential therapeutic effects such as antioxidant and anti-inflammatory effects. In the transportation of hydrogen, the gas-liquid separation effect of hydrogen and water is very important. In the process of water electrolysis, hydrogen will inevitably carry water vapor. In addition, when hydrogen is transported in a pipeline, changes in ambient temperature may also cause the generation or condensation of water vapor. For example, when hydrogen enters a low-temperature pipeline from a high-temperature environment, water vapor easily condenses into small water droplets on the inner wall of the pipeline. The current hydrogen delivery device of the hydrogen and oxygen atomizer has an unsatisfactory water removal effect.

[0004] If there is water in the hydrogen delivery pipeline, it will dilute the purity of the hydrogen and affect its therapeutic effect; it may change the size, distribution and uniformity of the atomized particles; when there are water droplets in the hydrogen, the fluid state in the pipeline becomes complicated, and the water droplets will increase the viscosity of the hydrogen, increasing the resistance encountered by the hydrogen when flowing in the pipeline.

[0005] In addition, since the hydrogen and oxygen atomizer is an electrical device with an internal circuit system, if the water in the hydrogen delivery pipeline leaks into the equipment, it may contact the circuit components and cause a short circuit. Short circuits will not only damage the equipment, but may also generate electric sparks. Since hydrogen and oxygen are flammable gases, electric sparks may cause combustion or even explosion, posing a serious safety hazard. Removing water can effectively avoid such safety accidents caused by water. Summary of the invention

[0018] A method for using a hydrogen gas transporting and dehydrating device for a hydrogen and oxygen atomizing machine, using any of the hydrogen gas transporting and dehydrating devices for a hydrogen and oxygen atomizing machine described above, the specific method is as follows: S1. The gas-liquid two-phase flow composed of mixed hydrogen and water enters from the horizontal interface of the three-way joint. After the gas enters the spiral tube, it mainly flows upward. Part of the water flows downward under the influence of gravity and flows out through the lower interface of the three-way joint. The other water flows upward with the gas and collides with the side wall during the rotating upward process. Under the action of centrifugal force and impact inertia, the water will separate from the hydrogen and flow down along the spiral tube to complete a filtration. S2, the guide piece 1 in the three-way joint can block the upward movement of water, and the guide piece 2 and the guide piece 3 form an S-shaped channel, which can prolong the passage time of hydrogen and reduce the amount of hydrogen going downward; and the guide piece 1, the guide piece 2, and the guide piece 3 are arranged in an inclined direction to increase the contact area with the hydrogen carrying water. When the hydrogen collides with it, the water will remain on the guide piece, thereby improving the water separation efficiency; the guide piece 1, the guide piece 2, and the guide piece 3 are secondary filtration of hydrogen; S3, when the filter cotton absorbs less water, the air permeability is good and the air pressure is low. When the gas moves upward from the air outlet, it first gradually enters the cavity on the lower end surface of the extrusion ring. During the filling process, part of the water will remain on the inner wall of the extrusion ring and then fall under the influence of gravity. Here, the hydrogen is filtered three times by delaying the outflow rate of hydrogen. The remaining water will move from the outside through the gap between the extrusion ring and the blocking sheet (32) and be filtered for the fourth time by the filter cotton to remove water. When the filter cotton absorbs more water, the air permeability is reduced, the gas cannot be discharged, and remains in the housing, resulting in an increase in the internal air pressure. The extrusion ring increases the extrusion force on the filter cotton, which will squeeze out the water inside the filter cotton. As the water is squeezed out, the air permeability of the filter cotton is improved, and the gas can pass through the filter cotton, so that the air pressure in the water removal device is reduced, and the cycle is repeated in sequence. S4. The separated water in the accommodating shell is collected at the bottom of the lower conical tube. In the initial state, the lower surface of the limit ring 1 is in contact with the upper surface of the water accumulation platform. At this time, the height of the drainage hole is within the range of the water accumulation platform, and the drainage hole is closed, and no water is discharged at this time; when more water is accumulated, the buoyancy generated by the water pushes the airbag upward, driving the sliding tube to move upward, and the lower surface of the limit ring 1 is no longer in contact with the upper surface of the water accumulation platform. At this time, the height of the drainage hole is greater than the height of the water accumulation platform, the drainage hole is opened, and drainage begins. During the drainage process, the amount of water decreases, resulting in a decrease in buoyancy. The height of the airbag and the sliding tube decreases under the influence of gravity and returns to the initial state.

[0019] The beneficial effects of the present invention are: 1. A spiral separation component is arranged inside the housing, including a connected three-way joint and a gradually spiral spiral tube. The spiral radius of the spiral tube changes from small to large. The mixed gas-liquid two-phase flow enters from the horizontal interface of the three-way joint. After the gas enters the spiral tube, it flows upward. Part of the liquid flows downward under the influence of gravity and flows out through the lower interface of the three-way joint. The other liquid flows upward with the gas and collides with the side wall during the rotating upward process. Under the action of centrifugal force and impact inertia, water will be separated from hydrogen and flow down along the pipeline; 2. A drainage filter assembly is designed at the upper end of the spiral tube. Medical absorbent filter cotton is used to filter hydrogen and absorb moisture. Filter cotton is set above the extrusion ring. When the gas flows upward, it can push the extrusion ring to squeeze the filter cotton to discharge moisture; 3. A water discharge component is set at the bottom of the housing, and a sliding pipe and a drain pipe with sliding connection are designed. An air bag is set on the drain pipe. According to the change of the water level of the accumulated water, the height of the drain pipe can be adjusted independently to drain the water in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] The inventors have found that the current hydrogen-oxygen atomizer hydrogen delivery device has an unsatisfactory water removal effect. If there is water in the hydrogen delivery pipeline, the purity of the hydrogen will be diluted, affecting its therapeutic effect; it may change the size, distribution and uniformity of the atomized particles; when there are water droplets in the hydrogen, the fluid state in the pipeline becomes complicated, and the water droplets increase the viscosity of the hydrogen, which increases the resistance of the hydrogen when it flows in the pipeline. In addition, since the hydrogen-oxygen atomizer is an electrical device, it has an internal circuit system. If the water in the hydrogen delivery pipeline leaks into the inside of the device, it may contact the circuit components and cause a short circuit. Short circuits will not only damage the equipment, but may also generate electric sparks. Since hydrogen and oxygen are flammable gases, electric sparks may cause combustion or even explosions, posing serious safety hazards. Water removal can effectively avoid such safety accidents caused by water.

[0023] Based on the above findings, the present application proposes a hydrogen transport and water removal device for a hydrogen and oxygen atomizer, wherein a spiral separation component 2 is arranged inside a housing 1, including a connected three-way joint 21 and a gradually spiral spiral tube 22, the spiral radius of the spiral tube 22 changes from small to large, and the mixed gas-liquid two-phase flow enters from the horizontal interface 211 of the three-way joint 21. After the gas enters the spiral tube 22, it flows upward, and part of the liquid flows downward under the influence of gravity and flows out through the lower interface 213 of the three-way joint 21, and the other liquid flows upward with the gas and collides with the side wall during the rotating upward process. Under the action of impact inertia, water will separate from hydrogen and flow down the pipeline; a drainage filter component 3 is designed at the upper end of the spiral tube 22, and a medical water-absorbing filter cotton 35 is used to filter the hydrogen and absorb moisture. The filter cotton 35 is arranged above the extrusion ring 34. When the gas flows upward, it can push the extrusion ring 34 to squeeze the filter cotton 35 to discharge moisture; a water discharge component 5 is arranged at the bottom of the housing 1, and a sliding tube 54 and a drain pipe 53 are designed to be slidably connected. An air bag 55 is arranged on the drain pipe 53. According to the change of the water level of the accumulated water, the height of the drain pipe 53 can be adjusted autonomously to drain water in time. Example

[0024] See also Figure 1 - Fig.17 The present application discloses a hydrogen conveying and dehydrating device for a hydrogen-oxygen atomizer, comprising a containing shell 1, a containing tube 11 having a cylindrical middle section and an upper conical tube 12 having a conical convergent shape at the upper end, the containing tube 11 and the upper conical tube 12 being integrally connected, and a lower conical tube 4 being movably connected to the lower end of the containing tube 11.

[0025] A spiral separation assembly 2 is arranged inside the housing tube 11, including a three-way joint 21, a horizontal interface 211 of the three-way joint 21 passes through the side wall of the housing tube 11 and the end thereof extends outward, and is used to be connected to the hydrogen output pipe 61 of the existing water electrolysis device 6. A gradually spiral spiral tube 22 is connected to the upper interface 212 of the three-way joint 21, and the spiral radius of the spiral tube 22 changes from small to large, with the smallest diameter at the end close to the three-way joint 21 and the largest diameter at the end away from the three-way joint 21.

[0026] The gas-liquid two-phase flow composed of the mixed hydrogen and water enters from the horizontal interface 211 of the three-way joint 21, and most of it goes upward along the pipeline and enters the spiral tube 22 whose spiral radius increases from small to large. During the rotating upward process, a high-speed rotating airflow is formed, which will also collide with the side wall. Because water is denser than hydrogen, under the action of centrifugal force and impact inertia, water will separate from hydrogen and flow down along the wall of the spiral tube 22.

[0027] The centrifugal force generated by the rotating airflow is mainly used for separation. The centrifugal forces on hydrogen and water are different. Water, due to its high density, will be thrown to the edge of the spiral tube 22, while hydrogen is concentrated in the area biased towards the center of rotation.

[0028] The spiral radius changes from small to large, which can prolong the residence time of hydrogen and water compared with ordinary straight tubes. In this process, the airflow moves along the spiral tube 22 to generate centrifugal force. Under the action of centrifugal force, water will be thrown to the edge of the spiral tube 22, adsorbed on the inner wall of the spiral tube 22, separated from the hydrogen, and then closed and fell along the spiral tube 22. In addition, its temperature can be reduced, thereby enhancing the temperature change effect, promoting the condensation and precipitation of water in the hydrogen, and enhancing the water-liquid separation effect. This part is the primary filtration of hydrogen.

[0029] A guide plate is also provided inside the three-way joint 21 to control the flow direction of hydrogen and block the moisture carried by the hydrogen.

[0030] A guide plate 23 is provided at the upper interface 212 of the three-way joint 21. The guide plate 23 is arranged at one end close to the horizontal interface 211 and is inclined downward. The guide plate 23 will block the incoming hydrogen to a certain extent, causing an impact effect. The hydrogen will continue to flow upward after the impact, while the moisture therein will be blocked and gathered and dripped downward.

[0031] A guide plate 24 is provided at the lower interface 213 of the three-way joint 21. The guide plate 24 is arranged at one end close to the horizontal interface 211 and is inclined downward. The guide plate 24 can guide the flowing water, reduce the diameter of the downward flow of hydrogen, and can largely block the downward flow of hydrogen, so that the hydrogen mainly flows upward through the spiral pipeline.

[0032] A guide piece 3 25 is also provided at the lower interface 213 of the three-way joint 21. The guide piece 3 25 is arranged at one end away from the horizontal interface 211, below the guide piece 2 24, and the angle is inclined downward. The guide piece 3 25 can receive the water flowing down, and the staggered design with the guide piece 2 24 can further block the hydrogen from flowing downward, so that the hydrogen mainly flows upward through the spiral pipeline. The guide piece 2 24 and the guide piece 3 25 form an S-shaped channel, which can extend the passage time of hydrogen and reduce the amount of hydrogen flowing downward. And the guide piece 1 23, the guide piece 2 24, and the guide piece 3 25 are arranged in an inclined direction to increase the contact area with the hydrogen carrying water. When the hydrogen collides with it, the water will remain on the guide piece, thereby improving the water separation efficiency. The guide piece 1 23, the guide piece 2 24, and the guide piece 3 25 are secondary filtration of hydrogen.

[0033] The gas-liquid two-phase flow composed of the mixed hydrogen and water enters from the horizontal interface 211 of the three-way joint 21. After the gas enters the spiral tube 22, it mainly flows upward due to its low density. Part of the water flows downward under the influence of gravity and is guided by the guide plate 24 and the guide plate 3 25, and flows out from the lower interface 213 of the three-way joint 21; other water flows upward with the gas and is blocked at the guide plate 1 23. Part of the water gathers and drips downward, and the other water collides with the side wall multiple times during the subsequent rotation and ascent. Under the action of centrifugal force and impact inertia, the water will be separated from the hydrogen and flow down along the pipeline. Example

[0034] A drainage filter assembly 3 is provided at the pipe opening of the upper conical pipe 12 , which can absorb and automatically process the moisture above the receiving pipe 11 .

[0035] The drainage filter assembly 3 includes a connecting pipe 31 integrally connected to the upper conical tube 12, the connecting pipe 31 is coaxially arranged with the accommodating tube 11, a plugging piece 32 is horizontally arranged at the position where the connecting pipe 31 is connected to the upper conical tube 12, a boss 33 is coaxially arranged above the plugging piece 32, and the boss 33 is integrally connected to the plugging piece 32. A through hole passing through the spiral tube 22 is arranged in the center of the plugging piece 32 and the boss 33, and a plurality of air outlets 321 surrounding the boss 33 are arranged on the plugging piece 32. An extrusion ring 34 is arranged around the boss 33, and the extrusion ring 34 covers the air outlet 321. The upper end face of the extrusion ring 34 is arc-shaped, and the lower end face has a cavity, and the material is selected from lightweight rubber. A ring-shaped medical water-absorbing filter cotton 35 is placed above the extrusion ring 34 to filter hydrogen and absorb moisture.

[0036] The extrusion ring 34 and the filter cotton 35 are both sleeved on the boss 33, and the outer diameter of the filter cotton 35 is larger than the outer diameter of the extrusion ring 34, and the inner diameter of the extrusion ring 34 is the same as the outer diameter of the boss 33, so that the inner outer wall of the extrusion ring 34 contacts the outer wall of the boss 33. The extrusion ring 34 is arranged above the air outlet 321 and covers the air outlet 321. When the gas moves upward from the air outlet 321, it first gradually enters the cavity of the lower end face of the extrusion ring 34. During the filling process, part of the water will stay on the inner wall of the extrusion ring 34, and then fall under the influence of gravity; here, the hydrogen is filtered three times by delaying the outflow speed of hydrogen. The remaining water will move from the outside through the gap between the extrusion ring 34 and the blocking sheet 32, and will be filtered for the fourth time through the filter cotton 35 to remove water. The connecting pipe 31 is detachably connected with a connecting seat 36, and the connecting pipe 31 and the connecting seat 36 can be set to be connected in a plug-in, threaded, or clamped manner, as long as the airtightness can be met. The connecting seat 36 includes a short tube 1, a connecting ring and a short tube 2 which are integrally connected. The short tube 1 is used to connect to the hydrogen end of the existing atomizer 8. The outer diameter of the short tube 2 is smaller than the outer diameter of the connecting ring, and the inner diameter of the short tube 2 is larger than the inner diameter of the filter cotton 35.

[0037] The end of the spiral tube 22 is inserted into the boss 33, and the hydrogen treated by the separation tube can enter the atomizer 8 through the connecting seat 36. Other gases located inside the housing 1 and outside the spiral tube 22 flow upward from the air outlet 321, and flow out through the filter cotton 35 through the gap around the extrusion ring 34. When the filter cotton 35 absorbs less water, the air permeability is good, the air pressure is low, and the force of the extrusion ring 34 on the filter cotton 35 is also low. When the filter cotton 35 absorbs more water, the volume becomes larger, the air permeability decreases, the gas cannot be discharged, and remains in the housing 1, resulting in an increase in the internal air pressure. The extrusion ring 34 increases the extrusion force on the filter cotton 35, which will squeeze out the water inside the filter cotton 35. After the water is squeezed out, it flows downward under the influence of gravity. As the water is squeezed out, the air permeability of the filter cotton 35 improves, and the gas can pass through the filter cotton 35, so that the air pressure in the water removal device is reduced, and it circulates in sequence.

[0038] After a certain period of use, the filter cotton 35 needs to be replaced regularly to maintain ventilation, filtration and water absorption. Example

[0039] The lower conical tube 4 is provided with a water discharge assembly 5. The lower conical tube 4 includes a receiving base 51 of a conical structure and a tubular drainage pipe 53 below. The receiving base 51 and the drainage pipe 53 are integrally connected through a water accumulation platform 52. The water accumulation platform 52 is an annular structure, and the inner diameter of the water accumulation platform 52 is smaller than the inner diameter of the drainage pipe 53. A sliding tube 54 is slidably connected in the drainage pipe 53. The sliding tube 54 is a tubular structure with a cavity inside. The two ends of the sliding tube 54 are integrally connected with a limiting ring 1 541 and a limiting ring 2 542. The limiting ring 1 541 is located at one end close to the receiving base 51, and the limiting ring 2 542 is located at one end close to the sliding tube 54, which can limit the upward and downward movement path of the sliding tube 54. An airbag 55 filled with air is fixedly connected above the sliding tube 54. The airbag 55 is fixedly connected to the limiting ring 1 541. A plurality of drainage holes 543 are opened along the circumferential surface of one end of the sliding tube 54 close to the limiting ring 1 541.

[0040] The separated water in the containing shell 1 is collected at the bottom of the lower conical tube 4, i.e., the water accumulation platform 52. In the initial state, the lower surface of the limiting ring 1 541 contacts the upper surface of the water accumulation platform 52. At this time, the height of the drain hole 543 is within the range of the water accumulation platform 52, and the drain hole 543 is closed. At this time, no water is discharged, and the inside of the containing shell 1 is isolated from the sliding tube 54, which can prevent hydrogen from flowing out of the sliding tube 54 and prevent foreign substances from entering in the opposite direction to pollute the hydrogen. When more water is accumulated, the buoyancy generated by the water pushes the airbag 55 upward, driving the sliding tube 54 to move upward, and the lower surface of the limiting ring 1 541 is no longer in contact with the upper surface of the water accumulation platform 52. At this time, the height of the drain hole 543 is greater than the height of the water accumulation platform 52, and the drain hole 543 is opened to start draining. During the drainage process, the amount of water decreases, resulting in a decrease in buoyancy. The height of the airbag 55 and the sliding tube 54 decreases under the influence of gravity and returns to the initial state.

[0041] In addition, since both sides of the sliding pipe 54 and the drainage pipe 53 are filled with water during the drainage process, the direct connection between the interior of the housing 1 and the sliding pipe 54 can be blocked to prevent hydrogen from leaking therefrom. The circulation can not only drain water in time, but also reduce the probability of hydrogen leakage and contamination.

[0042] In addition, a device for receiving water is connected below the drain pipe 53, which can also serve as a protective device for hydrogen leakage to avoid direct circulation with the external environment.

[0043] When the dehydration device is used, the horizontal interface 211 of the three-way joint 21 is connected to the hydrogen output pipe 61 of the water electrolysis device 6, and the oxygen output pipe 62 of the water electrolysis device 6 is connected to the oxygen input end of the atomizer 8 through the existing oxygen pipeline 7. After the hydrogen removes water in the dehydration device, it enters the atomizer 8 and is finally discharged from the breathing port 81 of the atomizer 8.

[0044] The principle of water removal by the water removal device is: 1. A gas-liquid two-phase flow composed of mixed hydrogen and water enters from the horizontal interface 211 of the three-way joint 21. After the gas enters the spiral tube 22, it mainly flows upward due to its low density. Part of the water flows downward under the influence of gravity and is guided by the guide plate 24 and the guide plate 3 25, and flows out from the lower interface 213 of the three-way joint 21; other water flows upward with the gas and is blocked at the guide plate 1 23. Part of the water gathers and drips downward, and the other water collides with the side wall multiple times during the subsequent rotation and ascent. Under the action of centrifugal force and impact inertia, the water will be separated from the hydrogen and flow down along the pipeline.

[0045] 2. The end of the spiral tube 22 is inserted into the boss 33, and the hydrogen treated by the separation tube can enter the atomizer 8 through the connecting seat 36. Other gases located inside the housing 1 and outside the spiral tube 22 flow upward from the air outlet 321, and flow out through the filter cotton 35 through the gap on the periphery of the extrusion ring 34. When the filter surface absorbs less water, the air permeability is good, the air pressure is low, and the force of the extrusion ring 34 on the filter cotton 35 is also low. When the filter cotton 35 absorbs more water, the volume becomes larger, the air permeability decreases, the gas cannot be discharged, and remains in the housing 1, resulting in an increase in the internal air pressure. The extrusion ring 34 increases the extrusion force on the filter cotton 35, which will squeeze out the water inside the filter cotton 35. After the water is squeezed out, it flows downward under the influence of gravity. As the water is squeezed out, the air permeability of the filter cotton 35 improves, and the gas can pass through the filter cotton 35, so that the air pressure in the water removal device is reduced, and it circulates in sequence.

[0046] 3. The separated water in the containing shell 1 is collected at the bottom of the lower conical tube 4, i.e., the water accumulation platform 52. In the initial state, the lower surface of the limit ring 1 541 contacts the upper surface of the water accumulation platform 52. At this time, the height of the drain hole 543 is within the range of the water accumulation platform 52, and the drain hole 543 is closed. At this time, no water is discharged, and the inside of the containing shell 1 is isolated from the sliding tube 54, which can prevent hydrogen from flowing out of the sliding tube 54 and prevent foreign substances from entering in the opposite direction to pollute the hydrogen. When more water is accumulated, the buoyancy generated by the water pushes the airbag 55 upward, driving the sliding tube 54 to move upward, and the lower surface of the limit ring 1 541 is no longer in contact with the upper surface of the water accumulation platform 52. At this time, the height of the drain hole 543 is greater than the height of the water accumulation platform 52, and the drain hole 543 is opened to start draining. During the drainage process, the amount of water decreases, resulting in a decrease in buoyancy. The height of the airbag 55 and the sliding tube 54 decreases under the influence of gravity and returns to the initial state.

A method for using a hydrogen gas transport and water removal device for a hydrogen and oxygen atomizer, characterized in that: The specific method of using the hydrogen gas transport and water removal device for the hydrogen and oxygen gas atomizer according to any one of claims 1 to 9 is as follows: S1, a gas-liquid two-phase flow consisting of a mixture of hydrogen and water enters from the horizontal interface (211) of the three-way joint (21), and the gas mainly flows upward after entering the spiral tube (22), and part of the water flows downward under the influence of gravity and flows out through the lower interface (213) of the three-way joint (21), and the rest of the water flows upward with the gas and collides with the side wall during the rotating upward process. Under the action of centrifugal force and impact inertia, the water is separated from the hydrogen and flows down along the spiral tube (22), completing a filtration; S2, the guide piece 1 (23) in the three-way joint (21) can block the upward movement of water, and the guide piece 2 (24) and the guide piece 3 (25) form an S-shaped channel, which can prolong the passage time of hydrogen and reduce the amount of hydrogen flowing downward; and the guide piece 1 (23), the guide piece 2 (24), and the guide piece 3 (25) are arranged in an inclined direction to increase the contact area with the hydrogen carrying water, and when the hydrogen collides with the guide piece, the water will remain on the guide piece, thereby improving the water separation efficiency; the guide piece 1 (23), the guide piece 2 (24), and the guide piece 3 (25) are secondary filters for hydrogen; S3, when the filter cotton (35) absorbs less water, the air permeability is good and the air pressure is low. When the gas moves upward from the air outlet (321), it first gradually enters the cavity on the lower end surface of the extrusion ring (34). During the filling process, part of the water will remain on the inner wall of the extrusion ring (34) and then fall down under the influence of gravity. Here, the hydrogen is filtered three times by delaying the outflow speed of the hydrogen. The remaining water will move from the outside through the gap between the extrusion ring (34) and the blocking plate (32) and pass through the filter cotton (35) for the fourth filtration to remove water. When the filter cotton (35) absorbs more water, the air permeability is reduced, the gas cannot be discharged, and remains in the housing (1), resulting in an increase in the internal air pressure. The extrusion force of the extrusion ring (34) on the filter cotton (35) increases, which will squeeze out the water inside the filter cotton (35). As the water is squeezed out, the air permeability of the filter cotton (35) is improved, and the gas can pass through the filter cotton (35), so that the air pressure in the water removal device is reduced, and the cycle is repeated in sequence. S4, the separated water in the containing shell (1) is collected at the bottom of the lower conical tube (4). In the initial state, the lower surface of the limiting ring (541) is in contact with the upper surface of the water accumulation platform (52). At this time, the height of the drainage hole (543) is within the range of the water accumulation platform (52), and the drainage hole (543) is closed, and no water is discharged at this time; when more water is accumulated, the buoyancy generated by the water pushes the airbag (55) upward, driving the sliding tube (54) to move upward, and the lower surface of the limiting ring (541) is no longer in contact with the upper surface of the water accumulation platform (52). At this time, the height of the drainage hole (543) is greater than the height of the water accumulation platform (52), and the drainage hole (543) is opened to start drainage. During the drainage process, the amount of water decreases, resulting in a decrease in buoyancy. The height of the airbag (55) and the sliding tube (54) decreases under the influence of gravity and returns to the initial state.
