Description

Technical Field

[0001] This invention relates to the field of nebulizer technology, and more specifically to a drug nebulizer that is easy to disassemble and clean. Background Technology

[0002] A drug nebulizer is a medical device that converts liquid drugs into tiny mists for patients to inhale to treat respiratory diseases. A drug jet nebulizer uses compressed air to impact the liquid drug and produce mist particles. The working principle of existing drug atomizers is as follows: The air compressor introduces high-pressure airflow into the drug atomizing container. The venturi nozzle causes the high-pressure airflow to rush out of the drug pool. The high-pressure airflow carries the drug and impacts the baffle to break up the drug droplets and form a mist. The high-pressure airflow carries the mist through the mouthpiece and delivers it into the patient's respiratory tract. However, existing drug atomizers have some drawbacks, such as: After one nebulization, some residual liquid will remain on the surfaces of parts such as the liquid pool, baffle, inner wall, and baffle cylinder inside the liquid nebulizer. Therefore, they need to be disassembled and cleaned one by one, which is very inconvenient and increases the workload of medical staff. A search revealed a utility model patent titled "A Pediatric Drug Nebulizer Inhaler," with patent authorization announcement number CN213609080U and authorization announcement date of July 6, 2021. The nebulizer bottle, partition one, partition two, and other structures in this patent adopt the conventional structure of the existing drug jet nebulizers. The disadvantage similar to existing drug jet nebulizers is that the nebulizer bottle is internally sealed, and the internal drug pool, partitions, and other components are not easy to clean.

[0003] Therefore, the present invention provides a drug nebulizer that is easy to disassemble and clean, in order to solve the above-mentioned problems. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a drug nebulizer that is easy to disassemble and clean, so as to solve the problem that the existing drug liquid nebulizer containers are not easy to clean internally.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A drug nebulizer that is easy to disassemble and clean includes a nebulizer housing and a nebulizer base; Atomizer housing: A central support column is fixed inside the atomizer housing, and inner rotating sleeves are rotatably installed at both the upper and lower ends of the central support column; Both ends of the atomizer housing are connected to connecting pipes that move up and down. A mist chamber is set inside the end of the atomizer housing. A baffle is installed inside the mist chamber. A baffle plate is fixedly connected inside the baffle. A lifting device is installed between the upper inner sleeve and the connecting pipe and between the lower inner sleeve and the baffle. When the inner sleeve rotates, the lifting device drives the two connecting pipes and the baffle to move up and down. A first transparent tube and a second transparent tube are fixedly connected between the two ends of the two inner spiral sleeves, respectively. The first transparent tube and the second transparent tube rotate between the two ends of the atomizer shell. A first channel is provided between the inner spiral sleeve, the first transparent tube and the second transparent tube. First transparent tube: The first transparent tube is fixedly connected to an inner pipe, which is connected to one of the connecting pipes. The other end of the connecting pipe connected to the inner pipe is connected to an external water pipe. Second transparent cylinder: A spray pipe is fixedly connected inside the second transparent cylinder. The spray pipe is connected to another connecting pipe. A water suction pipe and a liquid tank are installed at the end of the spray pipe. The spray pipe and the water suction pipe are aligned with the baffle. The lower end of the atomizer housing moves up and down and is inserted into the atomizer base. A locking assembly is installed between the inner sleeve and the atomizer base. The locking assembly locks and opens accordingly when the inner sleeve rotates in both directions. A hot air system is installed inside the atomizer base, which supplies hot air to one end of the atomizer housing. A common airflow and water flow channel is provided between the atomizer base and the other end of the atomizer housing. Through the above technical solution, the nozzle, water suction pipe, medicine pool and other parts inside the second transparent cylinder work. The nozzle sprays out high-pressure airflow, and through the principle of negative pressure, the medicine in the medicine pool is drawn into the airflow from the water suction pipe and hits the baffle on the baffle to generate mist, thus performing the conventional atomization function. When the inner rotating sleeve rotates, it can drive the first and second transparent cylinders to change positions, allowing them to switch places. It also separates parts such as the spray pipe, water suction pipe, and medicine pool from parts such as the baffle and mist pipe. Water flow and hot air flow can clean and dry these parts separately, avoiding drug residue and bacterial growth, thus achieving the cleaning function. Secondly, the lifting device can be used to control the connecting pipe and the baffle to move away from the first and second transparent cylinders, so that the inner connecting pipe is separated from the connecting pipe, the nozzle is separated from the connecting pipe, and the water suction pipe is separated from the baffle. This achieves the disassembly and separation of the atomizer shell, the first transparent cylinder and the second transparent cylinder, avoiding obstruction of the rotation of the first and second transparent cylinders. Furthermore, the lifting device can be used to control the connecting pipe and the baffle to move back closer to the first and second transparent cylinders, ensuring that the second transparent cylinder connects to another connecting pipe and the first transparent cylinder connects to the baffle. The first transparent cylinder, the second transparent cylinder, the atomizer shell and the atomizer base are sealed, so that the water flow and hot air flow can be sealed and not leaked, improving cleanliness. Thirdly, the locking assembly can automatically lock the atomizer shell and the atomizer base after the inner rotating sleeve is rotated into place, preventing accidental loosening or disassembly during use, ensuring structural stability and safety, and sealing the atomizer shell and the atomizer base. Under the aforementioned closed conditions, cleaning water is introduced from the external water pipe into the first transparent cylinder, the second transparent cylinder, the mist chamber, and the airflow and water flow common channel to complete the cleaning task. Meanwhile, the hot air system introduces hot air into the first transparent cylinder, the second transparent cylinder, the mist chamber, and the airflow and water flow common channel for drying, thus completing the cleaning and drying work. The system is completely sealed, ensuring that the water flow and hot air flow are sealed off and do not leak out. To perform the above three functions, the inner sleeve, the first transparent cylinder, and the second transparent cylinder need to be rotated 180°. When the inner sleeve, the first transparent cylinder, and the second transparent cylinder are rotated 90°, the liquid tank can be exposed. Before atomization, the liquid tank can be replenished to achieve the function of replenishing the liquid.

[0006] Preferably, the hot air system includes a third channel, a fan, a filter, a fourth channel, and an electric heating grid. The fourth channel is located inside the atomizer base, and a filter is fixedly connected to the air inlet of the fourth channel. An electric heating grid is fixedly connected to the fourth channel. The third channel is located inside the end of the atomizer housing, and the upper end of the third channel is connected to the first transparent tube. A fan is fixedly connected inside the third channel. After the atomizer housing is inserted into the atomizer base, the fourth channel connects with the third channel. Through the above technical solution, the filter intercepts dust and particulate matter in the outside air at the air inlet end of the fourth channel, preventing pollutants from entering the atomizer and ensuring clean and hygienic gas. The electric heating grid provides controllable heating of the clean air, providing a stable heat source for the drying process. The fan is installed in the third channel, actively and quickly sending hot air into the atomizer to achieve the drying function. The fourth channel and the third channel automatically connect when the atomizer shell is inserted into the atomizer base, without the need for additional pipeline connections, which facilitates overall assembly and maintenance.

[0007] Preferably, the upper end of the third channel is closed and a first through hole is arranged in a circular array. The third channel is connected to the first transparent cylinder through the first through hole. A first one-way rotating plate is rotated by a rotating shaft in the upper end of the third channel. The first one-way rotating plate is located above the first through hole and blocks the first through hole. A central convex ring is fixedly connected in the third channel. The middle part of the central convex ring protrudes upward. The central convex ring is located below a circle of first through holes. The central hole of the central convex ring is located directly below the center of the circle of first through holes. Through the above technical solution, the first one-way rotating plate and the first through hole cooperate to form a one-way valve structure, which only allows airflow to enter the first transparent cylinder from the third channel, preventing the liquid medicine, water vapor or mist in the atomizer from flowing back into the third channel and components such as the fan and electric heating grid, thus avoiding contamination and damage to the fan equipment. The center hole of the convex ring is offset from the first through hole to prevent seepage between the first one-way rotating plate and the first through hole from dripping onto the fan. Even if there is a small amount of seepage, it will drip onto the convex ring. In addition, the middle part of the convex ring is raised upward, which can accumulate a small amount of cleaning water, preventing the cleaning water from seeping onto the fan and damaging it.

[0008] Preferably, the airflow and water flow universal channel includes a second channel, a fifth channel, a sixth channel, and a seventh channel. One end of the second channel is connected to the first transparent tube and communicates with the upper end of the third channel. After the atomizer shell is inserted downward into the atomizer base, the other end of the second channel is connected to one end of the fifth channel. The fifth channel is located inside the atomizer base, and the other end of the fifth channel is connected to the sixth channel. The two ends of the sixth channel extend out of the two ends of the atomizer base, and the seventh channel is provided on the side of the sixth channel. The other end of the seventh channel is aligned with the baffle. A first sealing valve is fixedly connected to the upper end of the second channel, and a second sealing valve is fixedly connected to one end of the sixth channel. The other end of the sixth channel is connected to the mist pipe, which is connected to the mist chamber. With the above technical solution, the second channel and the fifth channel are automatically connected when the atomizer shell is inserted into the base, without the need for additional pipeline connection, which facilitates the quick assembly of the whole machine. The first sealing valve and the second sealing valve automatically close when not in operation or under reverse pressure difference, controlling the direction of airflow and water flow, preventing external impurities from entering the channel, and blocking the water flow, so that the cleaning water can completely immerse the medicine pool, baffle and other parts.

[0009] Preferably, the baffle includes a second through hole, a second one-way rotating plate, a third through hole, an inner cylinder, a threaded inner tube, a threaded outer tube, a limiting block, and a limiting groove. A limiting groove is provided on the side of the mist chamber. The limiting block moves vertically through the limiting groove and is fixedly connected to the side of the threaded outer tube. The threaded outer tube moves vertically through the mist chamber. A threaded inner tube is threaded inside the threaded outer tube. An inner cylinder is integrally formed inside the threaded inner tube. A baffle is fixed inside the upper end of the inner cylinder. The water suction pipe and the spray pipe are connected to the inner cylinder. The bottom of the cylinder has a circular array of third through holes, which connect the inner cylinder and the threaded inner tube. The lower end of the threaded inner tube has a second through hole. Inside the lower end of the threaded inner tube, there is a second one-way rotating plate that rotates via a shaft. The second one-way rotating plate blocks the second through hole. A push plate protrusion is integrally formed on the upper side of the inside of the atomizer base. When the atomizer shell is inserted into the atomizer base, the push plate protrusion passes through the second through hole and pushes open the second one-way rotating plate, so that the inner cavity of the inner cylinder is connected to the seventh channel through the second through hole. Through the above technical solution, the second one-way rotating plate cooperates with the push plate protrusion to automatically open the air and water passages when the atomizer is inserted into the base, allowing the flow of hot air and cleaning water. It automatically closes when pulled out, without the need for manual operation. The threaded outer tube moves up and down and is inserted into the mist chamber, allowing the entire baffle to move up and down. When the baffle moves down, it can prevent the inner tube from blocking the horizontal movement of the water suction pipe. When the baffle moves up, it can return to its original position. The limiting block moves up and down in the limiting groove, which can restrict the threaded outer tube to move only up and down, and can ensure that the threaded outer tube does not move when the threaded inner tube is screwed out.

[0010] Preferably, the lifting device includes a ball bearing, an arc-shaped protrusion, a lifting rod, and a first spring. The lifting rod moves up and down and is inserted into the middle support column or the atomizer housing. The first spring is fixedly connected between the lifting rod and the middle support column. After the lifting rod moves up and down, the first spring drives the lifting rod to return to its original position. A ball bearing rolls inside one end of the lifting rod. In the lifting device installed between the inner rotating sleeve and the connecting pipe, the arc-shaped protrusion is fixed on the upper side of the inner rotating sleeve, the upper end of the lifting rod is fixedly connected to the side of the connecting pipe, and the lifting rod and the ball move between the surface of the arc-shaped protrusion and the inner rotating sleeve. The lifting device installed between the inner sleeve and the stop cylinder has an arc-shaped protrusion fixed to the lower side of the inner sleeve, and the upper end of the lifting rod fixedly connected to the side of the threaded outer tube. The lifting rod and the ball move between the surface of the arc-shaped protrusion and the inner sleeve. Through the above technical solution, the forward and reverse rotation of the inner sleeve is transformed into the up and down linear motion of the connecting tube and the baffle by the cooperation of the arc-shaped protrusion, the ball bearing, and the lifting rod. When the inner sleeve rotates, it pushes the connecting tube or the baffle. After rotation, the first spring automatically pulls the lifting rod to reset. The operation is simple. The ball bearing rolls between the arc-shaped protrusion and the surface of the inner sleeve, which significantly reduces sliding friction. The upper lifting device controls the connecting tube to move upward, and the lower lifting device controls the baffle to move downward. The two move simultaneously to realize the synchronous opening or closing of the atomizer shell, the first transparent tube, and the second transparent tube, with coordinated and consistent movement.

[0011] Preferably, the locking assembly includes a first locking block and a second locking block. The first locking block is fixedly connected to the upper inside of the atomizer base, and the second locking block is fixedly connected to the lower end of the inner sleeve below. When the atomizer shell is inserted into the atomizer base, the first locking block and the second locking block are misaligned. After rotating the inner sleeve, the second locking block rotates to the lower part of the first locking block. With the above technical solution, the first locking block and the second locking block are staggered during insertion, eliminating the need for additional pressing or alignment. After insertion, simply rotating the inner sleeve will automatically lock the atomizer, making the operation simple and quick. This allows the locking and unlocking actions to be synchronized with the positional changes of the first and second transparent tubes. In the locked state, the second locking block is located below the first locking block, preventing the atomizer shell from being pulled out even if it is accidentally lifted. This avoids the shell from becoming loose due to collisions or pulling during use, ensuring safety during use.

[0012] Preferably, a sealing layer is fixedly connected between the middle end of the first transparent cylinder and the lower inner spiral sleeve. The upper height of the sealing layer is equal to the upper height of the first channel. The inner tube passes through the sealing layer, and a tube notch is provided at the lower end of the inner tube. The lower height of the tube notch is equal to the upper height of the sealing layer. Through the above technical solution, the sealing layer is fixedly connected between the middle end of the first transparent cylinder and the lower inner spiral sleeve, dividing the internal space of the first transparent cylinder into upper and lower regions. The upper height of the sealing layer is equal to the upper height of the first channel, ensuring that the outlet of the first channel is located exactly on the upper plane of the sealing layer. The inner pipe passes through the sealing layer from top to bottom, and its lower end extends into the area below the sealing layer for the flow of cleaning water or drying air. When it reaches the pipe opening, the water flows out from the pipe opening and falls into the mist chamber.

[0013] Preferably, the support plate is fixedly connected to the middle end of the nozzle, a second spring is fixedly connected to the lower side of the support plate, and a sealing sleeve is fixedly connected to the other end of the second spring. The sealing sleeve moves up and down around the bottom of the liquid tank. A fourth through hole is arranged in a circular array at the bottom of the liquid tank, and the sealing sleeve blocks the fourth through hole. With the above technical solution, the sealing sleeve is movably fitted onto the outside of the bottom end of the liquid tank. The second spring pushes the sealing sleeve to fit tightly against the outer wall of the bottom end of the liquid tank, completely blocking the fourth through hole arranged in a circular array at the bottom end, preventing the liquid from flowing out of the fourth through hole. When the hot air system is started or cleaning water is introduced, the water pressure or air pressure pushes open the sealing sleeve, causing the sealing sleeve to move upward relative to the liquid tank, exposing the fourth through hole for the cleaning water and hot air to flow through. This can both assist the liquid tank in holding the liquid and allow the sealing sleeve to be opened when the air pressure and water pressure are sufficient, allowing the cleaning water and hot air to flow through.

[0014] The beneficial effects of this invention are as follows: 1. Conventional atomization function: The nozzle, suction pipe, and liquid tank inside the second transparent cylinder work. The nozzle sprays out a high-pressure airflow, and through the principle of negative pressure, the liquid in the liquid tank is drawn into the airflow from the suction pipe and hits the baffle on the baffle to produce mist, thus performing the conventional atomization function. 2. Cleaning function generated by the inner rotating sleeve: When the inner rotating sleeve rotates, it can drive the first transparent cylinder and the second transparent cylinder to change positions, so that the first transparent cylinder and the second transparent cylinder are interchanged, and the spray pipe, water suction pipe, medicine pool and other parts are separated from the baffle pipe, mist pipe and other parts. Water flow and hot air flow can clean and dry these parts separately, avoiding drug residue and bacterial growth, thus achieving the cleaning function. 3. Prevent the connecting pipe and baffle from obstructing the water suction pipe, the first transparent cylinder and the second transparent cylinder when the inner rotating sleeve rotates: When the inner rotating sleeve rotates, the connecting pipe and baffle can be controlled by the lifting device to move away from the first transparent cylinder and the second transparent cylinder, so that the inner connecting pipe is separated from the connecting pipe, the spray pipe is separated from the connecting pipe, and the water suction pipe is separated from the baffle, thereby realizing the disassembly and separation of the atomizer shell, the first transparent cylinder and the second transparent cylinder, and avoiding obstruction of the rotation of the first transparent cylinder and the second transparent cylinder; 4. Reset and sealing function after inner sleeve rotation: The lifting device controls the connecting pipe and the baffle to move closer to the first transparent tube and the second transparent tube, ensuring that the second transparent tube connects to another connecting pipe, the first transparent tube connects to the baffle, and the first transparent tube connects to the baffle. The first transparent tube, the second transparent tube, the atomizer shell and the atomizer base are sealed, so that the water flow and hot air flow can be sealed and not leaked, improving cleanliness. 5. Locking function of atomizer shell and atomizer base after inner sleeve rotation: The locking component can automatically lock the atomizer shell and atomizer base after the inner sleeve is rotated into place, preventing accidental loosening or disassembly during use, ensuring structural stability and safety of use, and sealing the atomizer shell and atomizer base. 6. Cleaning and drying functions: In a closed system, cleaning water is introduced from the external water pipe into the first transparent cylinder, the second transparent cylinder, the mist chamber, and the airflow-water flow common channel to complete the cleaning task. Meanwhile, the hot air system introduces hot air into the first transparent cylinder, the second transparent cylinder, the mist chamber, and the airflow-water flow common channel for drying, thus completing the cleaning and drying work. The system is completely sealed to prevent water and hot air from leaking out. 7. Replenishment function: When the inner sleeve, the first transparent cylinder and the second transparent cylinder rotate 90°, the liquid tank can be exposed. Before atomization, the liquid tank can be replenished to achieve the function of replenishing the liquid.

[0015] In summary, this device can achieve the functions of replenishing medicine and atomization. When rotating the inner sleeve, the first transparent cylinder and the second transparent cylinder, the atomizer shell and the atomizer base are simultaneously connected and sealed to form corresponding water and air channels, so that the cleaning water and hot air system can clean and dry the inside of the atomizer.

Detailed Implementation

[0028] The following will refer to the attached reference. Figure 1 To be continued Figure 11 The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0029] As attached Figure 1 - Appendix Figure 11 As shown, a drug nebulizer that is easy to disassemble and clean includes a nebulizer housing 16 and a nebulizer base 26. Atomizer housing 16: See attached Figure 1 and attached Figure 4 A central support column 4 is fixed inside the upper end of the atomizer housing 16, and an inner rotating sleeve 9 is rotatably installed at both the upper and lower ends of the central support column 4. See appendix Figure 4 There are two connecting pipes 2 that move up and down at both ends of the upper half of the atomizer housing 16. One connecting pipe 2 moves up and down and is inserted into the external water pipe 1. The external water pipe 1 is threaded through the atomizer housing 16. The other end of the external water pipe 1 is connected to an external cleaning water pump to supply cleaning water to the external water pipe 1. The other connecting pipe 2 moves up and down and is inserted into the compressed air connection pipe 35. The compressed air connection pipe 35 is threaded through the atomizer housing 16. The other end of the compressed air connection pipe 35 is connected to an external air compressor to supply compressed air to the compressed air connection pipe 35. See appendix Figure 4 and attached Figure 7 A mist chamber 29 is provided in the lower half of the nebulizer housing 16. A mist tube 27 is connected to the side of the mist chamber 29. A mouthpiece 36 is movably inserted into the mist tube 27. The patient bites on the mouthpiece 36 to perform nebulization treatment. At the same time, the mouthpiece 36 can also be replaced with a breathing mask, nasal cannula or other parts for nebulization in the oral cavity and nasal cavity. See appendix Figure 1 and attached Figure 4The two inner spiral sleeves 9 are fixedly connected to the two ends of the first transparent tube 3 and the second transparent tube 32 respectively. The upper ends of the first transparent tube 3 and the second transparent tube 32 are closed structures. The first transparent tube 3 and the second transparent tube 32 are both made of transparent acrylic material. Two sealing rings 30 are fixedly connected to the lower end of the atomizer shell 16. One sealing ring 30 is sandwiched between the first transparent tube 3 and the atomizer shell 16 to improve the sealing performance. The other sealing ring 30 is sandwiched between the second transparent tube 32 and the atomizer shell 16 to improve the sealing performance. The front and rear of the atomizer shell 16 are open structures, which allows the first transparent tube 3 and the second transparent tube 32 to rotate between the left and right ends of the atomizer shell 16 and to be exposed when the first transparent tube 3 and the second transparent tube 32 rotate to the front or rear of the atomizer shell 16. A first channel 8 is provided between the lower inner spiral sleeve 9, the first transparent tube 3 and the second transparent tube 32 to connect the interiors of the first transparent tube 3 and the second transparent tube 32. See appendix Figure 4 First transparent cylinder 3: The inner pipe 5 is fixedly connected inside the first transparent cylinder 3. The inner pipe 5 is connected to the connecting pipe 2 which is connected to the external water pipe 1. A sealing layer 7 is fixedly connected between the middle end of the first transparent cylinder 3 and the lower inner sleeve 9. The sealing layer 7 separates the inner cavity of the first transparent cylinder 3 vertically. The upper height of the sealing layer 7 is equal to the upper height of the first channel 8, so that the first channel 8 is connected to the upper half of the inner cavity of the first transparent cylinder 3. The inner pipe 5 passes through the sealing layer 7. A pipe notch 6 is provided at the lower end of the inner pipe 5. The lower height of the pipe notch 6 is equal to the upper height of the sealing layer 7. See appendix Figure 4 The second transparent cylinder 32 is fixedly connected to a nozzle 34. The upper end of the nozzle 34 is connected to the connecting pipe 2 that is connected to the compressed air connecting pipe 35. The lower end of the nozzle 34 is equipped with a water suction pipe 33 and a liquid medicine pool 45. A Venturi nozzle is formed between the lower end of the nozzle 34 and the water suction pipe 33. When the compressed gas is sprayed out, a negative pressure is generated, which causes the liquid medicine in the liquid medicine pool 45 to flow through the clamp between the lower end of the nozzle 34 and the water suction pipe 33. A baffle 28 is installed in the mist chamber 29. A baffle 31 is fixedly connected in the baffle 28. The nozzle 34 and the water suction pipe 33 are aligned with the baffle 31. The nozzle 34, water suction pipe 33, liquid medicine pool 45, baffle 28 and baffle 31 mentioned above are common jet atomizer structures in the prior art, and will not be described in detail here. The lower ends of the first transparent cylinder 3 and the second transparent cylinder 32 are both closed structures with a gap in the middle. The upper end of the baffle 28 moves upward through the gap. Lifters 37 are installed between the upper inner rotating sleeve 9 and the connecting pipe 2 and between the lower inner rotating sleeve 9 and the baffle 28. When the inner rotating sleeve 9 rotates, the lifters 37 drive the two connecting pipes 2 and the baffle 28 to move up and down. See appendix Figure 4and attached Figure 5 A support plate 41 is fixedly connected to the middle end of the nozzle 34. A second spring 42 is fixedly connected between the support plate 41 and the sealing sleeve 43. The sealing sleeve 43 is movably sleeved around the bottom end of the liquid tank 45. A fourth through hole 44 is arranged in a circular array at the bottom end of the liquid tank 45. The sealing sleeve 43 blocks the fourth through hole 44. See appendix Figure 1 and attached Figure 4 The lower end of the atomizer housing 16 is inserted into the atomizer base 26 and moves up and down. A locking assembly is installed between the inner sleeve 9 and the atomizer base 26. The locking assembly locks and opens accordingly when the inner sleeve 9 rotates in both directions. See appendix Figure 4 A hot air system is installed inside the atomizer base 26. The hot air system supplies hot air to one end of the atomizer housing 16. A common airflow and water flow channel is provided between the atomizer base 26 and the other end of the atomizer housing 16.

[0030] As attached Figure 4 As shown, the hot air system includes a third channel 15, a fan 17, a filter 19, a fourth channel 20 and an electric heating grille 21. The fourth channel 20 is located inside the atomizer base 26. The filter 19 is fixedly connected inside the air inlet of the fourth channel 20, and the electric heating grille 21 is fixedly connected inside the fourth channel 20. The third channel 15 is located inside the end of the atomizer housing 16. The upper end of the third channel 15 is connected to the first transparent tube 3. A fan 17 is fixedly connected inside the third channel 15. After the atomizer housing 16 is inserted into the atomizer base 26, the fourth channel 20 is connected to the third channel 15. The hot air system works as follows: When the lower end of the atomizer housing 16 is inserted into the atomizer base 26, the fourth channel 20 and the third channel 15 are connected. External air first enters the fourth channel 20 through the filter 19. Impurities in the air are intercepted by the filter 19 and purified. The clean air continues to enter the interior of the fourth channel 20 and is heated when it passes through the electric heating grille 21 to form hot air. The hot air then flows from the fourth channel 20 into the third channel 15. In the third channel 15, the fan 17 drives the hot airflow to quickly enter the interior of the second transparent cylinder 32. The hot airflow is discharged after passing through the first channel 8, the first transparent cylinder 3, the mist chamber 29, the mist pipe 27, and the airflow and water flow common channel.

[0031] As attached Figure 4As shown, the upper end of the third channel 15 is closed and a first through hole 12 is arranged in a circular array. The third channel 15 is connected to the first transparent cylinder 3 through the first through hole 12. A first one-way rotating plate 11 is rotated by a rotating shaft in the upper end of the third channel 15. The first one-way rotating plate 11 is located above the first through hole 12 and blocks the first through hole 12. A central convex ring 13 is fixedly connected in the third channel 15. The middle part of the central convex ring 13 protrudes upward. The central convex ring 13 is located below a circle of first through holes 12. The central hole of the central convex ring 13 is located directly below the center of a circle of first through holes 12. The working method is as follows: When the fan 17 starts working, the airflow flows from the lower end to the upper end of the third channel 15. The airflow first passes through the middle convex ring 13. The middle part of the middle convex ring 13 convexes upward, which gathers the airflow towards the center, so that the airflow is concentrated and aligned with the center area of ​​the first through hole 12 above. The airflow continues to impact the first one-way rotating plate 11 upward, causing the first one-way rotating plate 11 to rotate upward and open. At this time, the first through hole 12 is exposed, and the airflow enters the interior of the second transparent cylinder 32 through the first through hole 12. When the fan 17 stops working or reverse airflow occurs, the first one-way rotating plate 11 automatically falls under the action of gravity or reverse airflow pressure, and re-blocks the first through hole 12. The center hole of the central convex ring 13 is located directly below the center of the first through hole 12, ensuring that no liquid will drip from the first through hole 12 onto the fan 17, whether it is opened in the forward direction or closed in the reverse direction.

[0032] As attached Figure 4 As shown, the airflow and water flow universal channel includes a second channel 14, a fifth channel 23, a sixth channel 24, and a seventh channel 25. One end of the second channel 14 is connected to the first transparent tube 3 and communicates with the upper end of the third channel 15. After the atomizer shell 16 is inserted downward into the atomizer base 26, the other end of the second channel 14 is connected to one end of the fifth channel 23. The fifth channel 23 is set inside the atomizer base 26, and the other end of the fifth channel 23 is connected to the sixth channel 24. The two ends of the sixth channel 24 extend out of the two ends of the atomizer base 26, and the seventh channel 25 is set on the side of the sixth channel 24. The other end of the seventh channel 25 is aligned with the baffle 28. A first sealing valve 10 is fixedly connected to the upper end of the second channel 14, a second sealing valve 22 is fixedly connected to one end of the sixth channel 24, and the other end of the sixth channel 24 is connected to the mist pipe 27. The working principle of the airflow and water flow universal channel is as follows: when the atomizer housing 16 is inserted downward into the atomizer base 26, the second channel 14 and the fifth channel 23 are automatically connected. When the hot air system is working, hot air passes through the third channel 15, the first through hole 12, the second transparent cylinder 32, the first channel 8, the first transparent cylinder 3, the mist chamber 29 and the mist pipe 27. Then, part of the airflow passes through the seventh channel 25 and enters the sixth channel 24, and the other part of the airflow passes through the mist pipe 27 and merges into the sixth channel 24. The second sealing valve 22 is opened, and finally the airflow is discharged from the sixth channel 24. When cleaning water is introduced, the water flow is supplied by an external water pump, passing through external water pipe 1, connecting pipe 2, spray pipe 34, second transparent cylinder 32, first channel 8, upper part of first transparent cylinder 3, connecting pipe notch 6, inner connecting pipe 5, baffle 28, seventh channel 25, mist pipe 27 and sixth channel 24. After the first sealing valve 10 and the second sealing valve 22 are opened, the water flows out.

[0033] As attached Figure 4 and attached Figure 5 As shown, the baffle 28 includes a second through hole 2801, a second one-way rotating plate 2802, a third through hole 2803, an inner cylinder 2804, a threaded inner tube 2805, a threaded outer tube 2806, a limiting block 2807, and a limiting groove 2808. A limiting groove 2808 is provided on the side of the mist chamber 29. The limiting block 2807 moves vertically through the limiting groove 2808. The limiting block 2807 is fixedly connected to the side of the threaded outer tube 2806. The threaded outer tube 2806 moves vertically through the mist chamber 29. The threaded inner tube 2805 is threadedly inserted into the threaded outer tube 2806. The inner cylinder 2804 is integrally formed inside the threaded inner tube 2805. A baffle 31 is fixed inside the upper end of the inner cylinder 2804. The water suction pipe 33 and the spray pipe 34 are connected to it. Inside the inner cylinder 2804, a third through hole 2803 is arranged in a circular array at the bottom end of the inner cylinder 2804. The inner cylinder 2804 and the threaded inner tube 2805 are connected through the third through hole 2803. A second through hole 2801 is arranged at the lower end of the threaded inner tube 2805. A second one-way rotating plate 2802 is rotated through a rotating shaft inside the lower end of the threaded inner tube 2805. The second one-way rotating plate 2802 blocks the second through hole 2801. A push plate protrusion 40 is integrally formed on the upper side of the inside of the atomizer base 26. When the atomizer shell 16 is inserted into the atomizer base 26, the push plate protrusion 40 passes through the second through hole 2801 and pushes open the second one-way rotating plate 2802, so that the inner cavity of the inner cylinder 2804 is connected to the seventh channel 25 through the second through hole 2801. The working method of the baffle 28 is as follows: when the atomizer housing 16 is inserted downward into the atomizer base 26, the push plate protrusion 40 passes through the second through hole 2801 and pushes the second one-way rotating plate 2802 upward, so that the second one-way rotating plate 2802 rotates around the rotating shaft and opens. At this time, the inner cavity of the inner cylinder 2804 is connected to the seventh channel 25 through the second through hole 2801. When the inner sleeve 9 moves the baffle 28 up and down through the lifting device 37, the threaded outer tube 2806 slides up and down in the limiting groove 2808. When the atomizer housing 16 is pulled upwards out of the atomizer base 26, the push plate protrusion 40 exits the second through hole 2801, and the second one-way rotating plate 2802 automatically falls back under the action of gravity, re-blocking the second through hole 2801 and cutting off the connection between the inner cylinder 2804 and the seventh channel 25.

[0034] As attached Figure 3 Appendix Figure 8 Appendix Figure 9 and attached Figure 11 As shown, attached Figure 9 The slender and unnecessary parts are removed. The lifting device 37 includes a ball bearing 3701, an arc-shaped protrusion 3702, a lifting rod 3703 and a first spring 3704. Each lifting device 37 includes two lifting rods 3703. The lifting rods 3703 move up and down and are inserted into the middle support column 4 or the atomizer housing 16. The first spring 3704 is fixedly connected between the lifting rod 3703 and the middle support column 4. After the lifting rod 3703 moves up and down, the first spring 3704 drives the lifting rod 3703 to return to its original position. A ball bearing 3701 rolls inside one end of the lifting rod 3703. In the lifting device 37 installed between the inner rotating sleeve 9 and the connecting pipe 2, the arc-shaped protrusion 3702 is fixed on the upper side of the inner rotating sleeve 9, the upper end of the lifting rod 3703 is fixedly connected to the side of the connecting pipe 2, the arc-shaped protrusion 3702 is located between the two lifting rods 3703, and the lifting rod 3703 and the ball 3701 move between the surface of the arc-shaped protrusion 3702 and the inner rotating sleeve 9. In the lifting device 37 installed between the lower inner sleeve 9 and the stop cylinder 28, the arc-shaped protrusion 3702 is fixed on the lower side of the inner sleeve 9, the upper end of the lifting rod 3703 is fixedly connected to the side of the threaded outer tube 2806, the arc-shaped protrusion 3702 is located between the two lifting rods 3703, and the lifting rod 3703 and the ball 3701 move between the surface of the arc-shaped protrusion 3702 and the inner sleeve 9. The working principle of the elevator 37 is as follows: Installed in the upper lifting device 37: When the inner rotating sleeve 9 rotates, the arc-shaped protrusion 3702 rotates with it. The protruding part of the arc-shaped protrusion 3702 gradually pushes the ball 3701 at the end of the lifting rod 3703, so that the lifting rod 3703 overcomes the tension of the first spring 3704 and moves upward, thereby driving the connecting tube 2 to move upward. Then, when the inner rotating sleeve 9 continues to rotate, the ball 3701 and the lifting rod 3703 leave the arc-shaped protrusion 3702, and the first spring 3704 pulls the lifting rod 3703 downward to reset, driving the connecting tube 2 to move downward back to its original position. Installed in the upper lifting device 37: When the inner rotating sleeve 9 rotates, the arc-shaped protrusion 3702 rotates with it. The protruding part of the arc-shaped protrusion 3702 gradually pushes the ball 3701 at the end of the lifting rod 3703, causing the lifting rod 3703 to move downward against the tension of the first spring 3704, thereby driving the stop cylinder 28 to move downward. Then, when the inner rotating sleeve 9 continues to rotate, the ball 3701 and the lifting rod 3703 leave the arc-shaped protrusion 3702, and the first spring 3704 pulls the lifting rod 3703 downward to reset, driving the stop cylinder 28 to move upward back to its original position.

[0035] As attached Figure 4 and attached Figure 5 As shown, the locking assembly includes a first locking block 38 and a second locking block 39. The first locking block 38 is fixedly connected to the upper inside of the atomizer base 26, and the second locking block 39 is fixedly connected to the lower end of the inner spiral sleeve 9 below. When the atomizer housing 16 is inserted into the atomizer base 26, the first locking block 38 and the second locking block 39 are misaligned. After rotating the inner spiral sleeve 9, the second locking block 39 rotates to the lower part of the first locking block 38. The locking assembly works as follows: when the atomizer housing 16 is inserted downward into the atomizer base 26, the second locking block 39 fixed at the lower end of the inner rotating sleeve 9 and the first locking block 38 fixed on the upper side inside the atomizer base 26 are axially offset and do not interfere with each other, so the atomizer housing 16 can be smoothly inserted into the base. After the atomizer housing 16 is inserted into place, rotate the inner sleeve 9. The second locking block 39 rotates synchronously with the inner sleeve 9 and gradually moves to directly below the first locking block 38. At this time, the first locking block 38 and the second locking block 39 form an overlapping relationship. The first locking block 38 blocks the second locking block 39 from above, preventing the inner sleeve 9 and the atomizer housing 16 from being pulled upward. When it is necessary to remove the atomizer housing 16, rotate the inner screw sleeve 9 to make the second locking block 39 rotate away from directly below the first locking block 38 and return to the offset position. At this time, the atomizer housing 16 can be pulled upward.

[0036] A controller 18 is fixedly connected to the side of the atomizer base 26. The input terminal of the controller 18 is electrically connected to the output terminal of an external AC power source, and the output terminal of the controller 18 is electrically connected to the input terminals of the fan 17, the heating grid 21, the first sealing valve 10, and the second sealing valve 22.

[0037] The working principle of this device is as follows: In the appendix Figure 1-9 and attached Figure 11 Based on this, and in conjunction with the appendix Figure 10 This device has four states when in use: plug-in state a, rinsing state b, drying state c, and handheld atomization state d. Plug-in state a: In this state, the atomizer housing 16 is inserted into the atomizer base 26, the external water pipe 1, the connecting pipe 2 and the internal connecting pipe 5 are connected, and the compressed air connecting pipe 35, the connecting pipe 2 and the nozzle 34 are connected. In this state, atomization, rinsing and drying are not performed. Based on the insertion state a, rotate the inner rotating sleeve 9, the first transparent cylinder 3 and the second transparent cylinder 32. When the inner rotating sleeve 9 rotates, it drives the two connecting pipes 2 to move upward and then downward through the lifting device 37. The baffle 28 moves downward and then upward. For the specific movement mode, refer to the working mode of the lifting device 37 above. After the two connecting pipes 2 and the baffle 28 move away from the first transparent cylinder 3 and the second transparent cylinder 32, they move closer to the first transparent cylinder 3 and the second transparent cylinder 32 again. During this up and down movement, the inner connecting pipe 5 is disconnected from the connecting pipe 2 and the nozzle 34 is disconnected from the connecting pipe 2. Then the upper and lower ends of the first transparent cylinder 3 and the second transparent cylinder 32 are no longer obstructed on the horizontal plane, and the first transparent cylinder 3 and the second transparent cylinder 32 can rotate horizontally until the first transparent cylinder 3 and the second transparent cylinder 32 rotate 180° to reach the rinsing state b. The locking component locks the atomizer shell 16 and the atomizer base 26. Flushing state b: External water pipe 1, connecting pipe 2 and spray pipe 34 are connected, while compressed air connecting pipe 35, connecting pipe 2 and internal connecting pipe 5 are connected. Flushing work begins in this state. The external water pump supplies water, and the water flows through external water pipe 1, connecting pipe 2, spray pipe 34, lower half of second transparent cylinder 32, liquid pool 45, fourth through hole 44, upper half of second transparent cylinder 32, first channel 8, upper half of first transparent cylinder 3, connecting pipe notch 6, internal connecting pipe 5, baffle 28, seventh channel 25, mist pipe 27 and sixth channel 24. When the flushing water is about to submerge or has already submerged the first transparent cylinder 3 and the second transparent cylinder 32, the water supply is stopped, and the first sealing valve 10 and the second sealing valve 22 are opened. The water flows out from the sixth channel 24, and then drying state c is performed. Drying state c: External water pipe 1, connecting pipe 2 and spray pipe 34 are still connected, while compressed air connecting pipe 35, connecting pipe 2 and internal connecting pipe 5 are still connected, that is, the connection state remains unchanged. Drying begins in this state. Hot air passes through the third channel 15, the first through hole 12, the lower half of the second transparent cylinder 32, the liquid pool 45, the fourth through hole 44, the upper half of the second transparent cylinder 32, the first channel 8, the first transparent cylinder 3, the mist chamber 29 and the mist pipe 27. Then, part of the airflow passes through the seventh channel 25 and enters the sixth channel 24, and the other part of the airflow passes through the mist pipe 27 and merges into the sixth channel 24. The second sealing valve 22 is opened, and finally, the airflow is discharged from the sixth channel 24. In the drying state c, first rotate the inner sleeve 9. According to the working principle described above, the inner sleeve 9, the first transparent cylinder 3, and the second transparent cylinder 32 rotate. When the inner sleeve 9 rotates, the lifting device 37 drives the two connecting pipes 2 to move upward and then downward. The baffle cylinder 28 moves downward and then upward. For the specific movement method, refer to the working method of the lifting device 37 above. After the two connecting pipes 2 and the baffle cylinder 28 move away from the first transparent cylinder 3 and the second transparent cylinder 32, they move closer to the first transparent cylinder 3 and the second transparent cylinder 32 again, returning to the insertion state a. The locking assembly is opened, and then the atomizer shell 16 is pulled out for handheld atomization. Handheld nebulizer mode d: First, rotate the inner sleeve 9, the first transparent tube 3, and the second transparent tube 32 by 90° instead of 180° to expose the medicine pool 45. Pour the medicine into the medicine pool 45, then rotate it back 90° to return it to its original position. The external air compressor sprays compressed air from the compressed air connecting pipe 35, the connecting pipe 2, and the nozzle 34. Through the principle of negative pressure, the medicine in the medicine pool 45 is sucked out from the gap between the suction pipe 33 and the nozzle 34. The medicine is sprayed out with the airflow and hits the baffle 31 to form an aerosol. The aerosol is delivered from the notch of the second transparent tube 32, the mist pipe 27, and the mouthpiece 36 for the patient to inhale.
