[0003] Chinese Patent with publication number CN208911167U discloses a new type of atomizing inhalation device. Through the setting of a medium and high temperature disinfection chamber, the atomizing nozzle can be disinfected and sterilized, improving its use safety; the setting of a storage groove can store the atomizing tube, avoiding its loss after disassembly; the setting of a snap ring allows the user to bite the snap ring, eliminating the need to hold the atomizing nozzle with the hand all the time, ensuring the stability between the atomizing nozzle and the face, reducing the nursing intensity of the staff. This atomizing inhalation device has diverse functions and is convenient for popularization.

[0004] In the above patent, during the atomization process, it is impossible to perform preparation operations for different medicament solutions, which may cause the situation that after atomization, the particles of some medicaments are relatively large and precipitate and adhere, thus affecting the atomization absorption effect.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1-2, an embodiment provided by the present invention: an atomizing inhalation device for automatically identifying and dispensing medicaments based on the Internet of Things, including an atomizer main body 1, and further including a transfer chamber 104, an assembly chamber 1011, an atomization chamber 1021, and an end oral cavity 1031. Among them, the assembly chamber 1011 is located below the dressing top cover 101, the transfer chamber 104 is arranged below the assembly chamber 1011, the end oral cavity 1031 is arranged on both sides of the transfer chamber 104, a mask hatch 103 is arranged on the outer surface of the end oral cavity 1031, the atomization chamber 1021 is arranged below the transfer chamber 104, a base 102 is arranged at the bottom of the atomization chamber 1021, medicament flow channels 1041 are arranged on both sides of the transfer chamber 104, ultrasonic components 5 are arranged at both ends inside the atomization chamber 1021, a water pump 503 is arranged below the ultrasonic components 5, and a screening pipe valve 6 is arranged above the ultrasonic components 5. The screening pipe valve 6 includes a steering interface 601 and a magnetron 602;

[0038] The medicament enters the transfer chamber 104 through the bottle body inside the assembly chamber 1011. If two medicaments are used in combination, they need to be mixed and stirred inside the transfer chamber 104. The stirred medicament will enter the atomization chamber 1021, and the ultrasonic components 5 cooperate with the water pump 503 to pump the medicament into the interior of the ultrasonic components 5 for atomization. The atomized medicament will be transported to the end oral cavity 1031 through a pipeline and used by connecting an external breathing mask through the steering interface 601.

[0039] Please refer to Figure 2-3 , a partition sleeve 504 is arranged inside the ultrasonic component 5. One end of the magnetron 602 is connected to the water pump 503 through the partition sleeve 504. Piezoelectric transducers 502 are arranged on both sides of the partition sleeve 504. A shock-absorbing cotton pad 501 is arranged on the outer side of the piezoelectric transducer 502. A conical atomization filter cover 603 is arranged inside the magnetron 602. A telescopic shaft seat 605 is arranged above the atomization filter cover 603. A blocking ring 604 below the atomization filter cover 603 is in fit connection with the magnetron 602. The outer diameter of the top of the atomization filter cover 603 is the same as the inner diameter of the blocking ring 604. An atomization through cavity 6011 is arranged above the atomization filter cover 603. The atomization filter cover 603 includes a liquid collection cavity 6033 and a particle sieve plate 6032. The particle sieve plate 6032 is located at the top of the liquid collection cavity 6033. The particle sieve plate 6032 is connected to the telescopic shaft seat 605 through a telescopic connecting rod 6051. A one-way valve nozzle 6031 is arranged at the bottom of the liquid collection cavity 6033;

[0040] The medicament atomized by the ultrasonic component 5 will enter the magnetron 602. The atomization filter cover 603 inside the magnetron 602 can be telescopically adjusted, so as to filter the atomized medicament passing through the magnetron 602 and further refine the atomized medicament particles. When filtration is required, the telescopic shaft seat 605 pushes the atomization filter cover 603 into the blocking ring 604 through the telescopic connecting rod 6051. At this time, the atomized medicament needs to pass through the particle sieve plate 6032 before it can enter the atomization cavity 6011. The large particle atomized medicament adsorbed by the particle sieve plate 6032 will gather in the conical liquid collection cavity 6033, and can be redropped into the ultrasonic component 5 through the one-way valve nozzle 6031 at the bottom of the liquid collection cavity 6033 for secondary atomization. When filtration is not required, the telescopic shaft seat 605 pulls the atomization filter cover 603 away from the blocking ring 604 through the telescopic connecting rod 6051. At this time, the atomized medicament enters the atomization cavity 6011 through the gap between the particle sieve plate 6032 and the blocking ring 604. At this time, the adsorption effect of the particle sieve plate 6032 on the large particle atomized medicament is limited, and the collected liquid medicine can also be redropped into the ultrasonic component 5 through the one-way valve nozzle 6031 at the bottom for secondary atomization.

[0041] Please refer to Figures 7-9, a filtering component is arranged inside the magnetron 602. The filtering component includes a first connecting pipe 701, and the first connecting pipe 701 is located below the atomizing filter cover 603. The outer wall of the first connecting pipe 701 is fixedly connected to the inner wall of the magnetron 602. A plug 702 is arranged at the lower end of the first connecting pipe 701. The plug 702 is set to be T-shaped and is fixedly connected to the lower end of the first connecting pipe 701. A number of communication holes 703 are arranged inside the plug 702. The upper and lower ends of the communication holes 703 respectively penetrate through the upper and lower surfaces of the plug 702. The number of communication holes 703 is distributed in an annular array around the center of the plug 702. A waterproof motor 704 is arranged below the plug 702. The waterproof motor 704 is fixedly connected to the plug 702 through a connecting rod 705. A rotating shaft 706 is arranged at the output end of the waterproof motor 704. One end of the rotating shaft 706 away from the waterproof motor 704 extends above the plug 702 and is provided with a first scraping plate 707. The lower surface of the first scraping plate 707 fits with the upper surface of the plug 702. The rotating shaft 706 is rotatably connected to the center of the plug 702. A second scraping plate 708 is further arranged on the rotating shaft 706. The second scraping plate 708 is located between the plug 702 and the waterproof motor 704. The upper surface of the second scraping plate 708 fits with the lower surface of the plug 702. The cross-sectional areas of both the first scraping plate 707 and the second scraping plate 708 are larger than the cross-sectional area of the communication hole 703. A blocking plate 709 is arranged above the first scraping plate 707. The outer periphery of the blocking plate 709 is fixedly connected to the inner wall of the first connecting pipe 701. A second connecting pipe 710 is arranged at the center of the blocking plate 709. A filtering seat 711 is arranged below the second connecting pipe 710. The filtering seat 711 has a hemispherical structure. The lower surface of the filtering seat 711 is fixedly connected to the upper end of the rotating shaft 706. The lower end of the second connecting pipe 710 is internally connected to the inside of the filtering seat 711. A number of filtering holes 712 are arranged on the filtering seat 711. A number of blocking rods 713 are arranged on the filtering seat 711 and the second connecting pipe 710. The blocking rods 713 are made of an elastic material. One end of the blocking rod 713 is fixedly connected to the inner wall of the filtering seat 711. A number of limiting grooves 714 are arranged on the outer wall of the second connecting pipe 710. The end of the blocking rod 713 away from the filtering seat 711 extends into the limiting groove 714;

[0042] The filtering component can filter the atomized medicament. Specifically, the atomized medicament enters the magnetron 602, and then the waterproof motor 704 is started. The rotation of the waterproof motor 704 drives the rotation of the rotating shaft 706. When the rotating shaft 706 rotates, it drives the first scraper 707 and the second scraper 708 to separate from the communication hole 703. Then, the atomized medicament can enter the first communication pipe 701 through the communication hole 703. Then, the atomized medicament entering the first communication pipe 701 can enter the interior of the filter seat 711 through the filter holes 712, and then flow from the second communication pipe 710 to the atomization filter cover 603. When the large-particle atomized medicament passes through the communication hole 703, it will be blocked by the lower end of the communication hole 703 and then get stuck at the lower end of the communication hole 703. The rotation of the second scraper 708 can scrape off the large-particle atomized medicament stuck at the lower end of the communication hole 703, preventing the communication hole 703 from being blocked, so that the large-particle atomized medicament drips back into the ultrasonic component 5 for secondary atomization. When the large-particle atomized medicament passes through the communication hole 703 and reaches the filter hole 712, the filter hole 712 will block the large-particle atomized medicament. The filter seat 711 rotates with the rotating shaft 706, so that the stop rod 713 separates from the limit groove 714 and then enters the next limit groove 714. Since the stop rod 713 is elastic, the stop rod 713 will vibrate when entering or leaving the limit groove 714, thereby driving the overall vibration of the filter seat 711, so that the large-particle atomized medicament stuck at the filter hole 712 falls on the upper end of the communication hole 703. The rotation of the first scraper 707 can break up the large-particle atomized medicament at the upper end of the communication hole 703, reduce the particle size of the large-particle atomized medicament, and then it can fall through the communication hole 703 or pass through the filter hole 712. When the atomization inhalation device is not working, the waterproof motor 704 controls the rotation of the rotating shaft 706, so that the first scraper 707 and the second scraper 708 block the communication hole 703, preventing external impurities from entering the ultrasonic component 5 through the magnetron 602 and affecting the quality of the atomized medicament, and ensuring the cleanliness of the atomized medicament.

[0043] Please refer to Figures 4-6 , a silent motor 4 is arranged inside the assembly cavity 1011. Medicine bottles 2 are arranged on both sides of the silent motor 4. Infrared scanning windows 3 are arranged on the surfaces of both sides of the silent motor 4. The output end of the infrared scanning window 3 is connected to the data reading module 301 for analyzing the label bar code in an interactive manner, and then interacts with the medicine database 303 containing different medicine information through the network data channel 302. The medicine database 303 includes a search engine module 3031, a verification unit 3032, and a retrieval unit 3033. Among them, the search engine module 3031 is responsible for retrieving the read medicine information in the database. After the retrieval is completed, the verification unit 3032 will conduct a comparison. After the comparison is confirmed, the retrieval unit 3033 will upload the medicine operation specifications to the control module inside the atomizer main body 1;

[0044] Before use, a label with a barcode needs to be attached to the surface of the medicine bottle 2. When in use, the medicine bottle 2 is inserted onto the sealing ring seat 203 inside the assembly cavity 1011, and the barcode label on its surface is rotated to the scanning area of the infrared scanning window 3. The infrared scanning window 3 reads the medicine information inside the barcode, and then uploads the read data to the medicine database 303 through the network data channel 302. Different medicine information and their usage specifications are collected in the medicine database 303. After the data is uploaded, the search engine module 3031 in the database will retrieve the read medicine information in the database. After the retrieval is completed, the verification unit 3032 will conduct a comparison. After the read data is confirmed and verified with the data recorded in the database, the retrieval unit 3033 will upload the operation specifications of the medicine to the control module inside the atomizer main body 1, so as to adjust the stirring speed of the motor and the atomization power of the atomization unit, achieving the optimal use effect of the medicine.

[0045] One end of the medicine bottle 2 is provided with a bottle body valve port 201. The bottle body valve port 201 is installed inside the sealing ring seat 203. A spring pressure valve 202 is arranged inside the sealing ring seat 203. The bottle body valve port 201 is connected to the spring pressure valve 202 through the medicine flow channel 1041. A transmission shaft 401 is arranged below the silent motor 4. A stirring blade 402 is arranged at the bottom of the transmission shaft 401. The stirring blade 402 is located inside the transfer cavity 104. The outer surface of the stirring blade 402 is provided with slots. A central gear 4011 is arranged between the transmission shaft 401 and the silent motor 4. Gear wheels 4012 are arranged on both sides of the central gear 4011. The gear wheels 4012 are meshed and rotationally connected with the central gear 4011. The gear wheels 4012 are in fit connection with the damping rubber ring 204 on the surface of the medicine bottle 2. A valve plate 4021 is arranged at the bottom of the stirring blade 402. A buffer bottom hopper 4022 below the valve plate 4021 is arranged at the top of the atomization cavity 1021. A valve port is arranged between the valve plate 4021 and the buffer bottom hopper 4022;

[0046] The silent motor 4 can drive the stirring blade 402 through the transmission shaft 401 to stir the medicine mixed inside the transfer cavity 104. The slot structure on the surface of the stirring blade 402 can play a role in guiding the medicine, thus avoiding the situation of generating bubbles when stirring the medicine;

[0047] During the stirring process of the silent motor 4, it will also drive the gear wheels 4012 on both sides to rotate synchronously by means of the central gear 4011. And the medicine bottle 2 and the sealing ring seat 203 can rotate, so when the gear wheels 4012 rotate, they can drive the medicine bottle 2 to rotate, thus avoiding the precipitation of the medicine in the medicine bottle 2.

[0048] It further includes a power adjustment device, which is electrically connected to the silent motor 4 and the control module respectively. The control module controls the operation of the silent motor 4 based on the average particle size of the pharmaceutical particles in the transfer chamber 104, including the following steps:

[0049] Step 1: Based on the average particle size of the pharmaceutical particles in the transfer chamber 104, calculate the target power of the silent motor 4 through the following formula:

[0050]

[0051] where P1 is the target power of the silent motor 4, n1 is the preset speed of the silent motor 4, D1 is the stirring diameter of the stirring blade 402, d1 is the average particle size of the pharmaceutical particles in the transfer chamber 104, ρ is the average density of the pharmaceutical particles in the transfer chamber 104, and N is the number of blades of the stirring blade 402;

[0052] Step 2: Based on the calculation result of Step 1, the control module controls the power adjustment device to adjust the actual power of the silent motor 4 to the target power of the silent motor 4.

[0053] To ensure a stable and constant speed when the silent motor 4 operates, a power adjustment device is also provided. The power adjustment device is used to adjust the actual power of the silent motor 4. Specifically, when the pharmaceutical enters the transfer chamber 104, first calculate the average particle size and average density of the pharmaceutical particles in the transfer chamber 104 through the input amount of different pharmaceuticals, and then calculate the target power of the silent motor 4 through the above formula. When calculating, the preset speed of the silent motor 4 is set according to user requirements. After obtaining the calculation result, the control module controls the power adjustment device to adjust the actual power of the silent motor 4 so that the actual power of the silent motor 4 reaches the calculated target power, thereby ensuring that the speed of the silent motor 4 always maintains the preset speed. The stirring speed of the stirring blade 402 will not change due to the different particle sizes or densities of the pharmaceutical particles in the transfer chamber 104. The stirring speed of the stirring blade 402 remains unchanged, ensuring the consistency of stirring, improving the stirring and mixing effect, being able to ensure that the pharmaceutical particles are fully stirred within the preset time, and ensuring the stirring efficiency.

[0054] Working principle: The medicament enters the transfer chamber 104 through the bottle body inside the assembly chamber 1011. If two medicaments are used in combination, they need to be mixed and stirred inside the transfer chamber 104. The stirred medicament will enter the atomization chamber 1021, and the ultrasonic component 5 cooperates with the water pump 503 to pump the medicament into the interior of the ultrasonic component 5 for atomization. The medicament atomized by the ultrasonic component 5 will enter the magnetron 602. The atomization filter cover 603 inside the magnetron 602 can be telescopically adjusted, so that the atomized medicament passing through the magnetron 602 can be filtered, and the atomized medicament particles can be further refined. When filtration is required, the telescopic shaft seat 605 pushes the atomization filter cover 603 into the blocking ring 604 through the telescopic connecting rod 6051. At this time, the atomized medicament needs to pass through the particle sieve plate 6032 to enter the atomization through cavity 6011, and the large-particle atomized medicament adsorbed by the particle sieve plate 6032 will gather in the conical liquid collection chamber 6033, and can be redropped into the ultrasonic component 5 through the one-way valve nozzle 6031 at the bottom of the liquid collection chamber 6033 for secondary atomization. When filtration is not required, the telescopic shaft seat 605 pulls the atomization filter cover 603 away from the blocking ring 604 through the telescopic connecting rod 6051. At this time, the atomized medicament needs to enter the atomization through cavity 6011 through the gap between the particle sieve plate 6032 and the blocking ring 604. At this time, the adsorption effect of the particle sieve plate 6032 on the large-particle atomized medicament is limited, and the collected liquid can also be redropped into the ultrasonic component 5 through the one-way valve nozzle 6031 at the bottom for secondary atomization.
