DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] In order to more clearly understand the above objects, features, and advantages of the present disclosure, the following will further describe the solutions of the present disclosure. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0030] Referring to Figure 1 and Figure 2 As shown, an atomizing oxygen supply device is provided in an embodiment of the present disclosure, including a face mask 1, an air storage bag 2, an atomizing cup 3, and an oxygen supply machine 4; an atomizing chamber 32 for accommodating a liquid medicine is formed in the atomizing cup 3, and an air inlet passage 34 and a mist outlet passage 35 communicating with the atomizing chamber 32 are provided on the atomizing cup 3; the air inlet passage 34 is connected to the oxygen supply machine 4, the mist outlet passage 35 is communicated with the air storage bag 2, and the air storage bag 2 is communicated with the face mask 1.

[0031] Specifically, the face mask 1 is a medical face mask, the face mask 1 can cover the mouth and nose of a patient, and an air pipe is provided on the face mask 1 and is communicated with the air storage bag 2. Of course, it can also be selected that an opening is provided on the face mask 1, a plastic interface is provided on the air storage bag 2, and the plastic interface is connected to the opening of the face mask 1 to communicate the face mask 1 with the air storage bag 2.

[0032] The above-mentioned air storage bag 2 can be selected as a bag body made of medical plastic, and the air storage bag 2 is hermetically connected to the face mask 1 and the atomizing cup 3, so that the liquid medicine atomized by oxygen in the atomizing cup 3 can be stored in the air storage bag 2, and the air storage bag 2 is filled with oxygen carrying atomized liquid medicine particles, so that the patient can inhale sufficient oxygen and atomized liquid medicine when inhaling.

[0033] The above-mentioned atomizing cup 3 is a medical atomizing cup, the atomizing chamber 32 is used for storing the liquid medicine, the air inlet passage 34 and the mist outlet passage 35 can be formed at both ends of the atomizing cup 3, and the oxygen supply machine 4 conveys oxygen into the atomizing chamber 32 through the air inlet passage 34. The oxygen blows the liquid medicine in the atomizing cup 3, so that the liquid medicine collides with the inner wall of the atomizing chamber 32 or a baffle provided in the atomizing chamber 32 to form small droplets. The small droplets are dispersed in the atomizing chamber 32, and the oxygen flows and carries the small droplets through the mist outlet passage 35 to discharge from the atomizing chamber 32, thereby completing the atomization operation of the liquid medicine in the atomizing chamber 32.

[0034] The above-mentioned oxygen supply machine 4 can be selected to be provided with an output pipe, and the output pipe is hermetically inserted into the air inlet passage 34. The oxygen supply machine 4 can continuously output oxygen, and the oxygen supply machine 4 can control the flow rate and air flow velocity of the output oxygen. The oxygen supply machine 4 continuously conveys oxygen into the atomizing chamber 32, so that the oxygen atomizes the liquid medicine in the atomizing cup 3 and then enters the air storage bag 2; the air storage bag 2 stores oxygen and atomized liquid medicine, and the patient can inhale the oxygen and atomized liquid medicine in the air storage bag 2 into the respiratory tract when inhaling, so as to complete the atomizing drug administration operation on the patient while maintaining oxygen supply to the patient.

[0035] When the atomizing oxygen supply device provided by the embodiment of the present disclosure is specifically used, the patient wears the mask 1. The air storage bag 2 is communicated with the mask 1 and the atomizing cup 3. The atomizing cup 3 is communicated with the oxygen supply machine 4. The liquid medicine is placed in the atomizing cavity 32. The oxygen supply machine 4 conveys oxygen to the atomizing cavity 32 through the air inlet channel 34. The oxygen atomizes the liquid medicine in the atomizing cavity 32 and discharges it from the atomizing cavity 32 through the mist outlet channel 35. The oxygen and the atomized liquid medicine are stored in the air storage bag 2. The patient inhales, and inhales the oxygen and the atomized liquid medicine in the air storage bag 2 into the respiratory tract, so that the atomizing oxygen supply device supplies oxygen to the patient, and at the same time the patient can inhale the atomized liquid medicine.

[0036] The atomizing oxygen supply device provided by the embodiment of the present disclosure includes a mask 1, an air storage bag 2, an atomizing cup 3 and an oxygen supply machine 4. An atomizing cavity 32 for accommodating the liquid medicine is formed in the atomizing cup 3. The atomizing cup 3 is provided with an air inlet channel 34 and a mist outlet channel 35 that are communicated with the atomizing cavity 32, so that the gas enters the atomizing cavity 32 through the air inlet channel 34 and atomizes the liquid medicine. The atomized liquid medicine can be discharged from the atomizing cavity 32 through the mist outlet channel 35. The air inlet channel 34 is connected to the oxygen supply machine 4, and the mist outlet channel 35 is communicated with the air storage bag 2. The air storage bag 2 is communicated with the mask 1. The oxygen conveyed by the oxygen supply machine 4 atomizes the liquid medicine in the atomizing cavity 32 and then sends it into the air storage bag 2 through the mist outlet channel 35. When the patient inhales oxygen, the patient can inhale the atomized liquid medicine at the same time. Through the atomizing oxygen supply device, the patient can continuously receive atomization treatment while inhaling oxygen, improving the treatment effect on the patient.

[0037] Refer to Figure 1 and Figure 2 As shown, in some embodiments, the atomizing cup 3 includes a cup body 31, a baffle 36 and a cup core 33. The atomizing cavity 32 is formed in the cup body 31. The air inlet channel 34 and the mist outlet channel 35 are respectively arranged on the inner walls of the opposite sides of the atomizing cavity 32. The cup core 33 is arranged on the inner wall of the atomizing cavity 32 opposite to the mist outlet channel 35. The air inlet channel 34 penetrates through the cup core 33, and an air outlet is formed at one end of the cup core 33 close to the mist outlet channel 35. The cup core 33 is provided with a liquid supply channel 333 located inside the atomizing cavity 32, and the liquid supply channel 333 forms a liquid inlet and a liquid outlet at both ends of the cup core 33 respectively. The liquid outlet and the air outlet are arranged at the same end of the cup core 33. The baffle 36 is arranged on the side of the cup core 33 close to the mist outlet channel 35. The baffle 36 is opposite to the air outlet and arranged at an interval. With such a setting, the air outlet and the liquid outlet are relatively close, and the air outlet is arranged opposite to the baffle 36. When the oxygen flows out from the air outlet and collides with the baffle 36, a negative pressure is formed at the liquid outlet, so that the liquid medicine is ejected from the liquid outlet through the liquid supply channel 333. The liquid medicine ejected from the liquid outlet collides with the baffle 36 together with the flow of oxygen, so that the liquid medicine forms small droplets and completes atomization, so that the oxygen supply machine 4 supplies oxygen to the atomizing cavity 32, and the liquid medicine in the atomizing cavity 32 can be continuously atomized.

[0038] Specifically, the cup body 31 can be selected as a columnar cup body structure with a hollow interior, and the space inside the cup body 31 serves as the atomization chamber 32; a detachable cover can be optionally provided on the cup body 31, and by opening the cover, the liquid medicine can be added into the atomization chamber 32.

[0039] The above-mentioned air inlet channel 34 and mist outlet channel 35 are respectively provided at both ends of the cup body 31, and both the air inlet channel 34 and the mist outlet channel 35 penetrate through the side wall of the cup body 31, so that both the air inlet channel 34 and the mist outlet channel 35 are communicated with the atomization chamber 32.

[0040] The above-mentioned cup core 33 can be selected as a columnar structure, and of course, it can also be selected as a conical structure. The cup core 33 is arranged on the inner wall of the atomization chamber 32, and the cup core 33 is arranged along the direction from the air inlet channel 34 towards the mist outlet channel 35. The air outlet is arranged at one end of the cup core 33 close to the mist outlet channel 35, and the liquid outlet is arranged around the air outlet; when the liquid medicine is stored in the atomization chamber 32, the liquid inlet is below the liquid level of the liquid medicine. The oxygen input into the air inlet channel 34 by the oxygen supply machine 4 enters the atomization chamber 32 through the air outlet. A negative pressure is generated at the liquid outlet due to the flow of oxygen, so that the liquid inlet sucks the liquid medicine into the liquid supply channel 333 and sprays it out from the liquid outlet. The liquid medicine sprayed out from the liquid outlet and the oxygen sprayed out from the air outlet collide with the baffle 36 together, so that the liquid medicine forms small droplets after colliding with the baffle 36 to complete atomization. The oxygen in the atomization chamber 32 carrying the small droplets formed by the liquid medicine enters the mask 1 through the mist outlet channel 35.

[0041] The above-mentioned baffle 36 can be optionally connected to one end of the cup core 33 close to the mist outlet channel 35 through a leg, so that the baffle 36 is arranged at an interval from the cup core 33. Of course, it can also be selected that the baffle 36 is connected to the inner wall of the atomization chamber 32 through a leg, so that the baffle 36 is arranged at an interval from the cup core 33.

[0042] The above-mentioned oxygen changes its traveling direction after colliding with the baffle 36 when flowing out from the air outlet, so that the oxygen bypasses the baffle 36 and flows out of the atomization chamber 32 through the mist outlet channel 35 after flowing out from the air outlet; when the oxygen collides with the baffle 36 when flowing out from the air outlet, a negative pressure is formed at the liquid outlet, so that the liquid medicine is sprayed out from the liquid outlet through the liquid supply channel 333. The liquid medicine sprayed out from the liquid outlet and the flow of oxygen collide with the baffle 36 together, so that the liquid medicine forms small droplets to complete atomization.

[0043] The above-mentioned liquid supply channel 333 can be selected as a pipeline structure arranged outside the cup core 33, and the pipeline structure is arranged along the extension direction of the cup core 33. The openings at both ends of the pipeline structure are respectively the liquid inlet and the liquid outlet; of course, it can also be selected that the cup core 33 has a channel arranged along the extension direction of the cup core 33 as the liquid supply channel 333.

[0044] Refer to Figure 1 and Figure 2As shown, in some embodiments, the cup core 33 includes a conical protrusion 331 and a conical sleeve 332; the conical protrusion 331 is connected to the inner wall of the atomization chamber 32, and in the direction close to the mist outlet channel 35, the diameter of the conical protrusion 331 gradually decreases; the air inlet channel 34 penetrates through the conical protrusion 331 along the axis of the conical protrusion 331, and an air outlet is formed at one end of the conical protrusion 331 close to the mist outlet channel 35; the conical sleeve 332 covers the outside of the conical protrusion 331, and a gas guiding opening opposite to the air outlet is provided on the conical sleeve 332. The inner wall of the conical sleeve 332 is spaced from the outer wall of the conical protrusion 331, and the edge of the conical sleeve 332 far from the mist outlet channel 35 is spaced from the inner wall of the atomization chamber 32, so that the space between the conical sleeve 332 and the conical protrusion 331 forms a liquid supply channel 333.

[0045] With such a setting, when the atomization cup 3 is in use, it usually hangs naturally. The axis of the conical protrusion 331 is arranged in the vertical direction. The liquid supply channel 333 formed by the conical protrusion 331 and the conical sleeve 332 is arranged obliquely relative to the vertical direction, so that the liquid medicine can be sucked into the liquid supply channel 333 from the liquid inlet even when the negative pressure formed at the liquid outlet is small, which is convenient for the atomization operation of the liquid medicine in the atomization chamber 32.

[0046] Specifically, the conical protrusion 331 can be selected as a frustum structure arranged on the inner wall of the atomization chamber 32. The end face with a larger area of the frustum structure is connected to the inner wall of the atomization chamber 32, and the end face with a smaller area of the frustum structure faces the mist outlet channel 35. The air inlet channel 34 penetrates through the conical protrusion 331 along the axis direction of the conical protrusion 331 to form an air outlet at one end of the conical protrusion 331 close to the mist outlet channel 35.

[0047] The above-mentioned conical sleeve 332 covers the outside of the conical protrusion 331. Multiple legs can be arranged on the edge of the conical sleeve 332 far from the mist outlet channel 35, and the multiple legs are connected to the inner wall on the side of the atomization chamber 32 opposite to the mist outlet channel 35, so that the inner wall of the conical sleeve 332 is spaced from the inner wall of the atomization chamber 32, and the inner wall of the conical sleeve 332 is spaced from the outer wall of the conical protrusion 331; of course, convex blocks can also be arranged on the inner wall of the conical sleeve 332, and the convex blocks are in contact with and connected to the inner wall of the conical protrusion 331, so that the inner wall of the conical sleeve 332 is spaced from the outer wall of the conical protrusion 331, and the edge of the conical sleeve 332 far from the mist outlet channel 35 is spaced from the inner wall of the side of the atomization chamber 32 where the air inlet channel 34 is provided, so that the space between the conical sleeve 332 and the conical protrusion 331 can form a liquid supply channel 333.

[0048] The space between the above-mentioned conical sleeve 332 and the conical protrusion 331 forms a liquid supply channel 333. An outlet is formed between the edge of the air guide opening on the conical sleeve 332 and the outer wall of the conical protrusion 331. An inlet is formed between the edge of the conical sleeve 332 away from the mist outlet channel 35 and the inner wall of the side of the atomization chamber 32 where the air inlet channel 34 is provided.

[0049] Referring Figure 2 As shown, in some embodiments, the cup body 31 includes an upper cover 311 and a lower cover 312. The upper cover 311 and the lower cover 312 are detachably connected. The upper cover 311 and the lower cover 312 together enclose an atomization chamber 32. The mist outlet channel 35 is provided on the upper cover 311, and the air inlet channel 34 is provided on the lower cover 312. With this arrangement, the structures of the upper cover 311 and the lower cover 312 are simple and the manufacturing cost is low. After separating the upper cover 311 from the lower cover 312, medical staff can add the liquid medicine into the lower cover 312, which is convenient for medical staff to replace or supplement the liquid medicine in the atomization chamber 32.

[0050] Specifically, a receiving groove is recessed on the side surface of the lower cover 312 facing the upper cover 311. When the upper cover 311 and the lower cover 312 are connected, the upper cover 311 blocks the notch of the receiving groove of the lower cover 312, and the space in the receiving groove forms the atomization chamber 32; the mist outlet channel 35 penetrates through the upper cover 311, and the air inlet channel 34 penetrates through the lower cover 312. After the upper cover 311 and the lower cover 312 are connected, the mist outlet channel 35 is communicated with the atomization chamber 32, and the air inlet channel 34 is communicated with the atomization chamber 32.

[0051] Threads can be selectively provided on the edge of the above-mentioned lower cover 312, and a surrounding plate is provided on the edge of the upper cover 311 with threads provided thereon, so that the upper cover 311 and the lower cover 312 are detachably connected by threads; of course, it can also be selected that the upper cover 311 and the lower cover 312 are detachably connected by bolts after being fitted together.

[0052] Referring Figure 2 As shown, in some embodiments, a drain pipe 21 is further provided on the air storage bag 2. The drain pipe 21 is communicated with the air storage bag 2, and a control valve 22 is provided on the drain pipe 21. With this arrangement, the control valve 22 controls the opening and closing of the drain pipe 21. The atomized liquid medicine enters the air storage bag 2, and the liquid droplets adsorbed on the inner wall of the air storage bag 2 by part of the atomized liquid medicine can be discharged from the air storage bag 2 through the drain pipe 21, which is convenient for cleaning the air storage bag 2.

[0053] Specifically, a hollow tube body can be optionally provided on the air storage bag 2 as a liquid discharge pipe 21. The control valve 22 can optionally include a stop piece and a rotating handle. The stop piece is arranged in the liquid discharge pipe 21, and the rotating handle is arranged outside the liquid discharge pipe 21 and connected to the stop piece. The stop piece has the same cross-sectional area as the liquid discharge pipe 21. When the rotating handle rotates, it can drive the stop piece to rotate in the liquid discharge pipe 21. When the stop piece is horizontally arranged in the liquid discharge pipe 21, the edge of the stop piece fits against the inner wall of the liquid discharge pipe 21 to prevent gas or liquid from passing through the liquid discharge pipe 21. When the stop piece is arranged along the extension direction of the liquid discharge pipe 21, a space for liquid or gas to pass through is formed between the edge of the stop piece and the inner wall of the liquid discharge pipe 21.

[0054] After the above-mentioned oxygen carries the atomized liquid medicine into the air storage bag 2, part of the atomized liquid medicine will contact the inner wall of the air storage bag 2, causing part of the atomized liquid medicine to adsorb on the inner wall of the air storage bag 2 to form liquid droplets. After continuously inputting the atomized liquid medicine into the air storage bag 2 for a long time, the liquid on the inner wall of the air storage bag 2 will converge at the bottom of the air storage bag 2. At this time, the control valve 22 is opened so that the liquid medicine can be discharged from the air storage bag 2 through the liquid discharge pipe 21.

[0055] Refer to Figure 1 and Figure 2 As shown in the figure, in some embodiments, the liquid discharge pipe 21 is arranged at one end of the air storage bag 2 away from the mask 1. With this arrangement, when the air storage bag 2 is in use, the liquid discharge pipe 21 is below the mask 1, and the liquid droplets on the inner wall of the air storage bag 2 can conveniently be discharged from the air storage bag 2 through the liquid discharge pipe 21 after converging.

[0056] Specifically, the liquid discharge pipe 21 and the mask 1 are respectively at opposite ends of the air storage bag 2. When the atomizing oxygen supply device is in use, the air storage bag 2 naturally hangs down under its own gravity. When the air storage bag 2 is in use, the end of the air storage bag 2 away from the mask 1 is below the mask 1, and the liquid droplets on the inner wall of the air storage bag 2 will converge at the end of the air storage bag 2 away from the mask 1. When the control valve 22 is opened, the liquid droplets converged in the air storage bag 2 can be discharged through the liquid discharge pipe 21 under the action of gravity.

[0057] Refer to Figure 1 and Figure 2 As shown in the figure, in some embodiments, an auxiliary pipe 37 is provided on the cup body 31. The auxiliary pipe 37 is communicated with the atomizing chamber 32. The auxiliary pipe 37 is used to connect with a liquid supply device so that the liquid supply device can input liquid medicine into the atomizing chamber 32 through the auxiliary pipe 37. With this arrangement, the liquid supply device inputs the liquid medicine into the atomizing chamber 32 through the auxiliary pipe 37, so that it is not necessary to disassemble the upper cover 311 to replenish the liquid medicine into the atomizing chamber 32, improving the operation convenience of replenishing the liquid medicine into the atomizing chamber 32.

[0058] Specifically, the auxiliary tube 37 on the cup body 31 can be selectively arranged at one end of the cup body 31 where the mist outlet channel 35 is provided. The liquid supply device can be selectively an infusion bottle and an infusion set. The infusion bottle contains the liquid medicine, and the infusion set is connected to the infusion bottle and the auxiliary tube 37. The liquid medicine in the infusion bottle can be input into the auxiliary tube 37 through the infusion set, so as to supplement the liquid medicine into the atomization chamber 32 in a timely manner. Of course, the liquid supply device can also be selectively composed of a liquid storage tank and a micro pump. The liquid medicine is carried in the liquid storage tank, and the micro pump is connected to the liquid storage tank and the auxiliary tube 37. After the micro pump is started, the liquid medicine in the liquid storage tank can be input into the atomization chamber 32.

[0059] Referring to Figure 1 and Figure 2 As shown, in some embodiments, a plug 371 is detachably installed at one end of the auxiliary tube 37 away from the cup body 31. With this setting, when the auxiliary tube 37 is not in use, the plug 371 blocks the auxiliary tube 37, preventing the gas in the atomization chamber 32 from flowing out of the atomization chamber 32 through the auxiliary tube 37.

[0060] Specifically, the plug 371 can be selectively a rubber head. The rubber head is inserted into one end of the auxiliary tube 37 away from the cup body 31, and the rubber head abuts against the inner wall of the auxiliary tube 37, so as to block the auxiliary tube 37 with the rubber head. Of course, the plug 371 can also be selectively a cylindrical structure. The side surface of the cylindrical structure is provided with threads, and the inner wall of the auxiliary tube 37 is provided with threads. The cylindrical structure is inserted into the auxiliary tube 37, and the cylindrical structure is threadedly connected to the auxiliary tube 37, so as to block the auxiliary tube 37 with the plug 371.

[0061] Referring to Figure 1 and Figure 2 As shown, in some embodiments, a first one-way valve 11 that is opened by inhalation is provided on the mask 1. The air storage bag 2 is communicated with the mask 1 through the first one-way valve 11. With this setting, when the patient inhales, the first one-way valve 11 can be opened to inhale the atomized gas in the air storage bag 2 into the mask 1. When the patient exhales, the first one-way valve 11 is in a closed state, preventing the gas exhaled by the patient from entering the air storage bag 2 and polluting the environment inside the air storage bag 2.

[0062] Specifically, the first one-way valve 11 can be selectively composed of a plurality of rubber sheets. The edges of the plurality of rubber sheets abut against each other to form a sealing sheet. When the gas enters the mask 1 from the side away from the patient's face to the side close to the patient's face, the plurality of rubber sheets can be pushed by the gas to move away from each other, enabling the gas to pass through the first one-way valve 11 and enter the interior of the mask 1.

[0063] Of course, it is also possible to select that the first one-way valve 11 includes a disc-shaped sealing piece. A connecting pipe is provided on the mask 1, and the connecting pipe is communicated with the air storage bag 2. The sealing piece is arranged inside the connecting pipe, and part of the edge of the sealing piece is rotatably connected to the inner wall of the connecting pipe. The edge of the sealing piece abuts against the inner wall of the connecting pipe to prevent gas from passing through the connecting pipe. A limiting member is arranged between the sealing piece and the connecting pipe. When the gas in the air storage bag 2 moves towards the mask 1 through the connecting pipe, the sealing piece can rotate relative to the connecting pipe, so that the sealing piece can rotate from the position blocking the connecting pipe to the position allowing the gas to pass through the connecting pipe; when the gas moves from the mask 1 to the air storage bag 2, the limiting member restricts the rotation of the sealing piece, so that the sealing piece remains in the position blocking the connecting pipe, so that the gas exhaled by the patient cannot enter the air storage bag 2 through the first one-way valve 11.

[0064] Referring Figure 1 and Figure 2 As shown, in some embodiments, a second one-way valve 12 that opens during exhalation is provided on the mask 1. With such a setting, when the patient exhales, the patient can exhale through the second one-way valve 12, and the second one-way valve 12 remains closed when the patient inhales, so that the patient can only inhale the oxygen and atomized liquid medicine in the air storage bag 2, and the second one-way valve 12 prevents the patient from inhaling the air outside the mask 1 into the inside of the mask 1 when inhaling.

[0065] Specifically, the second one-way valve 12 can be selected to be arranged on the mask 1, and the gas exhaled by the patient can pass through the second one-way valve 12 and be discharged from the inside of the mask 1, preventing the patient from inhaling the air outside the mask 1 into the inside of the mask 1 when inhaling.

[0066] When the atomizing oxygen supply device provided by the embodiment of the present disclosure is specifically used, the patient wears the mask 1, the liquid supply device is communicated with the auxiliary pipe 37, the oxygen supply machine 4 is started to supply oxygen into the atomizing chamber 32 through the air inlet channel 34, and the oxygen changes the traveling direction after colliding with the baffle 36 when flowing out of the air outlet, so that the oxygen bypasses the baffle 36 and flows out of the atomizing chamber 32 through the mist outlet channel 35 after flowing out of the air outlet; when the oxygen collides with the baffle 36 when flowing out of the air outlet, a negative pressure is formed at the liquid outlet, so that the liquid medicine is sprayed out of the liquid outlet through the liquid supply channel 333, and the liquid medicine sprayed out of the liquid outlet collides with the baffle 36 together with the flow of oxygen, so that the liquid medicine forms small droplets to complete atomization.

[0067] The atomized liquid medicine and oxygen together are discharged from the atomizing chamber 32 through the mist outlet channel 35 and enter the air storage bag 2. The air storage bag 2 is filled with oxygen and atomized liquid medicine. When the patient inhales, the first one-way valve 11 is opened, so that the oxygen and atomized liquid medicine in the air storage bag 2 enter the patient's respiratory tract together, and the gas exhaled by the patient is discharged from the mask 1 through the second one-way valve 12.

[0068] When the liquid medicine in the atomization chamber 32 is consumed and needs to be replenished, the liquid supply device replenishes the liquid medicine into the atomization chamber 32 through the auxiliary pipe 37 so that the atomization cup 3 can continuously atomize the liquid medicine; when droplets are formed by adsorbing part of the atomized liquid medicine on the inner wall of the air storage bag 2, the control valve 22 is opened to discharge the droplets in the air storage bag 2 through the drain pipe 21.
