DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, this application provides:

[0037] The invention discloses an anti-clogging self-cleaning compression nebulizer for eliminating drug residues, comprising a nebulizer body 1 and a rotor 2 rotatably arranged in the nebulizer body 1, wherein the nebulizer body 1 is provided with a drug liquid inlet, a pure water inlet 112 and a mist liquid outlet 113, two coaxial atomizing sheets 3 are respectively arranged at both ends of the nebulizer body 1, and the gas outlet sides of the two atomizing sheets 3 are opposite to each other, and the rotor 2 is provided with a gas-liquid channel 21 capable of connecting the gas outlet end of the atomizing sheet 3 with the pure water inlet 112 and the mist outlet, and a drug liquid channel 22 capable of connecting the back side of the atomizing sheet 3 with the drug liquid inlet, and a rotating drive component for guiding the rotor 2 to rotate in the nebulizer body 1 is provided on the outer side of the nebulizer body 1.

[0038] like Figure 5 As shown, the rotation drive assembly includes a gear 41 and a servo motor 42. The outer circumferential surface of the rotor 2 is provided with teeth distributed along its circumference. The gear 41 is rotatably arranged on the outside of the atomizer body 1. The gear 41 penetrates the atomizer body 1 and meshes with the teeth. The servo motor 42 is fixedly arranged on the outside of the atomizer body 1. The output shaft of the servo motor 42 is coaxially fixedly connected with the gear 41. When the servo motor 42 is started, the gear 41 rotates and drives the rotor 2 to rotate a certain angle in the atomizer body 1.

[0039] like Figure 4 As shown, a sealing shell 5 is further provided on the outer side of the atomizer body 1 , and the gear 41 and the servo motor 42 are both located in the sealing shell 5 , so as to prevent external pollution from corroding the gear 41 and the servo motor 42 .

[0040] A liquid medicine tank 16 threadedly connected to the liquid medicine inlet is provided.

[0041] The atomizer 3 is mainly composed of a piezoelectric ceramic ring and a metal diaphragm. When it is powered, the piezoelectric ceramic will generate high-frequency vibration, which in turn drives the copper sheet to vibrate and knock the water on the absorbent cotton strip, causing the water to spray out from the pores of the copper sheet to form mist.

[0042] In the initial state, there is a gas-liquid channel 21 connected to the mist liquid outlet 113, the atomizer sheet 3 connected to the gas-liquid channel 21 is started, and the liquid medicine channel 22 connected to the atomizer sheet 3 is connected to the liquid medicine inlet, so that the atomizer sheet 3 can work, and the atomizer sheet 3 vibrates the liquid medicine on its back side and sprays it out on its gas outlet side to form mist.

[0043] The mist is discharged outward through the gas-liquid channel 21, thereby realizing the atomization of the liquid medicine.

[0044] A mist volume sensor is also provided at the mist liquid outlet 113, and the mist volume sensor can check whether the mist volume generated by the atomizer is sufficient and uniform. If the mist volume is significantly reduced or uneven, it may be due to a blockage or failure of the atomizer.

[0045] When the small hole of the atomizing sheet 3 is blocked, the rotating driving assembly is started, so that the rotating driving assembly drives the rotor 2 to rotate in the atomizer body 1, so that another gas-liquid channel 21 that was not originally connected to the medicine liquid inlet is connected to the medicine liquid inlet, and then the back side of the atomizing sheet 3 on the other side is filled with medicine liquid, so that the atomizing sheet 3 is started for atomization, and the mist liquid outlet 113 connected to the blocked atomizing sheet 3 is connected to the pure water inlet 112, so that the pure water fills the air outlet side of the atomizing sheet 3, and the atomizing sheet 3 is started again, so that the medicine stains are discharged under the high-frequency vibration and the water pressure on one side of the small hole, thereby preventing the small hole of the atomizing sheet 3 from being blocked and unable to work normally.

[0046] This embodiment successfully solves the common problem of blockage of the atomizer sheet 3 by continuously switching and cleaning the replaced atomizer sheet 3. In practical applications, blockage of the atomizer sheet 3 often leads to a weakening or even complete loss of the atomization effect, thereby seriously affecting the effectiveness of atomization treatment.

[0047] The system can monitor the working status of the atomizer sheet 3 in real time. Once the atomizer sheet 3 is found to be blocked or its performance is degraded, the switching mechanism will be automatically activated. At this time, the system will replace the blocked atomizer sheet 3 with a spare atomizer sheet 3 to ensure that the nebulizer can work continuously and stably. This continuous switching mechanism not only avoids the interruption of treatment caused by the blockage of the atomizer sheet 3, but also ensures the continuity and stability of the atomization treatment process.

[0048] At the same time, in order to keep the atomizer sheet 3 clean and at optimal performance, the system is also equipped with a cleaning and replacement mechanism. After the atomizer sheet 3 has been used for a period of time, the system will automatically clean it to remove accumulated dirt and impurities.

[0049] By adopting this continuous switching and cleaning and replacement management method of the atomizer sheet 3, this embodiment effectively solves the problem of atomizer sheet 3 blockage, ensuring that the atomizer can work continuously and stably. This not only improves the efficiency and quality of atomization treatment, but also brings a better treatment experience to patients. Therefore, the atomizer management system of this embodiment has broad application prospects and important practical value.

[0050] like Figure 3 As shown, a buffer chamber 12 is provided in the atomizer body 1 on the back side of the atomizing plate 3, a collecting tank 13 is provided at the mist liquid outlet 113, a mist outlet is provided at the upper part of the collecting tank 13, and a drainage channel 23 that can connect the buffer chamber 12 and the collecting tank 13 is provided on the rotor 2.

[0051] A mist pipe 17 is provided at the mist outlet, and the breathing mask can be communicated with the mist pipe 17 .

[0052] In the design process of the nebulizer, in order to ensure its efficient and stable performance, a buffer cavity 12 located on the back side of the atomizer plate 3 is provided in the nebulizer body 1. The main purpose of this design is to optimize the process of the drug liquid entering the atomizer plate 3, so that the drug liquid can smoothly enter the buffer cavity 12 through the drug liquid inlet. The existence of the buffer cavity 12 not only ensures the uniform distribution of the drug liquid, but also prevents the drug liquid from directly impacting the atomizer plate 3, thereby extending the service life of the atomizer plate 3.

[0053] When the liquid medicine enters the buffer chamber 12, after proper dispersion and stabilization, it can ensure that the atomizing sheet 3 can continuously and stably generate mist. Such a design makes the atomization process more efficient, and the speed and amount of mist generation can be accurately controlled.

[0054] In addition, in order to achieve effective collection and discharge of mist, the atomizer is also provided with a collection tank 13 at the mist liquid outlet 113, and a mist outlet is arranged along the upper portion thereof, so that the mist generated from the atomizing sheet 3 can smoothly enter the collection tank 13 through the mist liquid channel. Once the mist enters the collection tank 13, it can be discharged outward through the mist outlet, providing the desired atomization effect for the user.

[0055] When the other mist sheet needs to be cleaned, the drug stains or drug residues discharged from the other side of the mist sheet will fall into the buffer chamber 12. The collection function of the buffer chamber 12 is utilized so that the drug stains and drug residues will not be directly scattered in the external environment. Subsequently, these drug stains and drug residues will smoothly fall into the collection tank 13 through the drainage channel 23. In this way, the user can conveniently collect and process the cleaned drug stains and drug residues, which not only facilitates the cleaning work, but also improves the hygiene of use.

[0056] In summary, by providing the buffer chamber 12 and the collection tank 13 in the atomizer body 1, and combining the synergistic effect of the liquid medicine inlet, the mist liquid channel, and the mist gas outlet, the efficient, stable, and hygienic use of the atomizer is achieved. Such a design not only improves the user experience, but also provides a more reliable technical guarantee for the atomization process of the liquid medicine.

[0057] like Figure 2 As shown, the liquid medicine inlet and the pure water inlet 112 are both located at the top of the nebulizer body 1 , and the mist outlet is located at the bottom of the nebulizer body 1 .

[0058] When the liquid medicine inlet and the pure water inlet 112 are cleverly designed at the top of the atomizer body 1, such a layout makes full use of the effect of gravity. Under the natural drive of gravity, the liquid medicine and pure water can flow smoothly into the atomizer body 1 without the need for additional pumping or pressure devices, thereby simplifying the operation process and improving the convenience of use.

[0059] The smooth entry of the drug solution and pure water not only provides the necessary material conditions for the atomization process, but also facilitates the subsequent cleaning and maintenance work. During the atomization process, the drug solution is converted into fine mist particles through the atomization sheet 3. When necessary, the pure water can generate appropriate water pressure on the drug stains in the small holes of the atomization sheet 3, help remove the accumulated impurities, and keep the atomization sheet 3 clean and unobstructed.

[0060] The mist outlet is located at the bottom of the atomizer body 1. The position of the bottom allows the mist outlet to be far away from the inlet of the liquid medicine and pure water, avoiding possible contamination and confusion. At the same time, since the mist accumulates and stabilizes inside the atomizer for a period of time, the mist discharged from the bottom can be more uniform and stable. Such a design ensures the quality and stability of the mist, making the atomization effect better and the user experience more comfortable.

[0061] In general, the layout of the liquid medicine inlet and the pure water inlet 112 at the top, and the design of the mist outlet at the bottom, together constitute an efficient, stable and convenient working system of the atomizer. Such a design not only improves the effect and quality of atomization, but also facilitates the user's use and maintenance, bringing a better user experience.

[0062] like Figure 3 As shown, the gas-liquid channel 21 has a central section that is coaxial with and connected to the gas outlet side of the atomizing plate 3, and an inclined section that can connect the central section with the pure water inlet 112 or the mist outlet.

[0063] By opening a central section coaxial with the rotor 2 at both ends and an inclined section at the inner end of the central section, the central section and the inclined section form a gas-liquid channel 21. When one of the gas-liquid channels 21 is connected to the mist liquid outlet 113 and the air outlet side of the atomizing sheet 3, the mist generated by the atomizing sheet 3 is discharged outward through the gas-liquid channel 21. After the rotor 2 rotates, the gas-liquid channel 21 can connect the pure water inlet 112 and the air outlet side of the atomizing sheet 3, so that the pure water generates water pressure on the drug stains in the small holes of the atomizing sheet 3 from the air outlet side, so that the atomizing sheet 3 can discharge the drug stains when vibrating.

[0064] like Figure 2 As shown, a pure water tank 14 connected to the pure water inlet 112 is provided on the pure water inlet 112. When the rotor 2 rotates in the atomizer body 1, the inclined section of one gas-liquid channel 21 is connected to the pure water inlet 112, and the inclined section of the other gas-liquid channel 21 is connected to the mist liquid outlet 113.

[0065] A pure water tank 14 is arranged on the pure water inlet 112 so that the pure water in the pure water tank 14 can flow into the atomizer body 1 by itself, so that the pure water flows to the air outlet side of the atomizer plate 3 through one of the gas-liquid channels 21, so that the pure water generates water pressure on the blockages in the small holes of the atomizer plate 3, so that the atomizer plate 3 can discharge the blockages when vibrating. The inclined section of the other gas-liquid channel 21 is connected to the mist liquid outlet 113, so that after the rotor 2 rotates, the pure water remaining in the gas-liquid channel 21 can flow into the collection tank 13, thereby preventing the pure water in the gas-liquid channel 21 from affecting the circulation of the mist.

[0066] like Figure 3 As shown, both ends of the atomizer body 1 are provided with closing covers 15 threadedly connected thereto, and a buffer chamber 12 for temporarily storing the drug solution is formed between the closing cover 15 and the atomizing plate 3 .

[0067] When the atomizer sheet 3 needs to be replaced, the user only needs to open the closing covers 15 at both ends to easily remove the old atomizer sheet 3 and install a new one. The existence of the buffer chamber 12 makes this operation process smoother and avoids the difficulty of replacement due to complex structure. At the same time, the buffer chamber 12 can also effectively collect tiny debris or residues that may be generated during the replacement process to ensure the internal cleanliness of the atomizer.

[0068] In addition, after the atomizing sheet 3 has been used for a period of time, some drug stains or drug residues may remain on its surface, and these drug residues cannot be removed in time. At this time, the user can also clean the atomizing sheet 3 by himself by opening the closing cover 15. The design of the buffer chamber 12 makes the cleaning process more convenient, and the user can easily scrape off and collect the drug stains or drug residues, avoiding secondary contamination caused by inconvenient cleaning.

[0069] like Figure 3 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the outer circumferential surface of the atomizer sheet 3 is provided with a coaxial rubber ring 31, the rubber ring 31 is interference fit with the inner wall of the atomizer body 1, and the rubber ring 31 is provided with a lower notch 311 capable of connecting the buffer cavity 12 and the discharge channel 23, and an upper notch 312 capable of connecting the buffer cavity 12 and the liquid channel 22.

[0070] By arranging a rubber ring 31 on the outer circumferential surface of the atomizer sheet 3, the atomizer sheet 3 can be buffered during high-frequency vibration, thereby reducing the vibration of the atomizer body 1, and can improve the sealing performance of the peripheral side of the atomizer sheet 3 to prevent the overflow of the drug solution or pure water. At the same time, the lower notch 311 can connect the buffer chamber 12 and the drainage channel 23, so that the drug stains or drug residues remaining in the buffer chamber 12 can flow to the collection tank 13 through the lower notch 311 and the drainage channel 23, and the drug solution in the drug solution channel 22 can flow to the buffer chamber 12 through the upper notch 312, so as to facilitate atomization.

[0071] like Figure 3 As shown, sealing rings 24 located on the end surfaces of the atomizing sheet 3 and the rotor 2 are provided at both ends of the rotor 2 .

[0072] By providing sealing rings 24 at both ends of the rotor 2, it is possible to effectively prevent the drug solution or pure water from overflowing through the gap between the rotor 2 and the atomizing sheet 3, thereby effectively improving the sealing performance of the structure.

[0073] like Figure 3 As shown, an inner conical ring 151 is provided at the inner end of the closing cover 15, and the inner diameter of the inner conical ring 151 gradually decreases from the rubber ring 31 to the other end thereof, and the inner inner diameter of the rubber ring 31 gradually decreases from the closing cover 15 to the other end thereof.

[0074] By setting an inner conical ring 151 at the inner end of the closing cover 15, the inner diameter of the rubber ring 31 gradually decreases from the closing cover 15 to the other end thereof, so that pure water or drug residues flow to the lower notch 311 of the rubber ring 31 under the action of the inclined surface, thereby facilitating discharge and preventing clogging in the buffer chamber 12.

[0075] The self-cleaning method of the anti-clogging self-cleaning compression nebulizer for eliminating drug residues is applied to the anti-clogging self-cleaning compression nebulizer for eliminating drug residues, and comprises the following steps:

[0076] Step 1: When one of the atomizing sheets 3 is blocked, the rotating drive assembly is started, and the rotor 2 rotates to connect the liquid medicine channel 22 connected to the blocked atomizing sheet 3 with the pure water inlet 112, and the pure water flows to the outlet side of the blocked atomizing sheet 3;

[0077] Step 2: start the clogged atomizer plate 3 . Under the action of water pressure on the gas outlet side of the atomizer plate 3 , the clogged foreign matter is separated from the atomizer plate 3 and discharged outward through the gas-liquid channel 21 .

[0078] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
