[0002] In existing technologies, micro-mesh nebulizers, as a new generation of inhaled drug delivery devices, have been widely used in the treatment of chronic respiratory diseases such as asthma and COPD due to their advantages such as low noise, high efficiency, and portability. However, current mainstream products still have the following key problems: Significant drug waste: The continuous nebulization mode means that the drug is still being sprayed during the exhalation phase, resulting in ineffective drug delivery. Furthermore, the rear cover and the nebulizer's internal housing are often integrally molded, making disassembly inconvenient. These issues urgently require improvement.

[0003] This invention aims to mitigate or at least alleviate such problems or defects by providing new or otherwise improved atomizers. Utility Model Content

[0004] In view of one or more of the above-mentioned defects or improvement needs of the prior art, this utility model provides a breathing-synchronous nebulizer, which has the advantages of avoiding the continuous nebulization mode, where the exhalation phase is still spraying, resulting in the ineffective emission of drugs, and the rear cover and the nebulizer's internal shell are often integrally formed, making them inconvenient to disassemble and assemble.

[0005] To achieve the above objectives, this utility model provides a breathing-synchronized nebulizer, which includes a built-in nebulizer housing with a built-in cavity inside, and a built-in nebulizer controller is detachably installed in the built-in cavity.

An upper channel plate is detachably mounted on the top of the front cover. A built-in sensor is located in the upper channel plate, and the upper channel plate is connected to the atomizer mouthpiece. Multiple air inlets are located in the upper channel plate.

[0008] As a further improvement of this utility model, a fastening opening is provided at the top of the atomizer's inner housing, and the fastening opening extends along the inner cavity of the atomizer's inner housing.

[0009] As a further improvement of this utility model, a flexible fastening plate can be detachably installed on the rear cover, and the flexible fastening plate is arranged in the direction of the fastening opening. When the flexible fastening plate is fastened into the atomizer's inner housing, the rear cover can be positioned on the atomizer's inner housing.

[0010] As a further improvement of this utility model, a breathing valve can be detachably installed in the upper channel plate, and the breathing valve is located below the multiple sets of air inlets.

[0011] As a further improvement of this utility model, a built-in charging port can be detachably installed at the bottom of the rear cover, and a cover for sealing the built-in charging port is provided.

[0012] As a further improvement of this utility model, the feeding box is made of transparent plastic and has multiple sets of scale lines, which can be used to read the amount of liquid remaining in the feeding box.

[0013] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0028] The overall concept behind this invention is as follows: A built-in controller 2 for the nebulizer employs a nebulization main control chip integrating ADC and PWM. It initiates or periodically performs frequency scanning, using the peak drive current as a feedback indicator to automatically search for and lock the optimal resonant frequency, achieving adaptive and efficient nebulization. A breathing valve 45, based on a miniature differential pressure sensor, detects the breathing flow rate in real time. Digital filtering and threshold judgment identify the inhalation / exhalation phases, triggering nebulization only during the inhalation phase. It also supports a pre-start / delayed shutdown compensation mechanism. The breathing valve 45, air inlet 44, upper channel plate 43, and nebulizer nozzle 42 are interconnected, enabling seamless drug delivery, avoiding choking, and effectively preventing drug waste. A flexible fastening plate 32 fastens to the nebulizer's internal housing 1, allowing for quick disassembly of the rear cover 3 and the nebulizer's internal housing 1, improving the nebulizer's practicality.

[0029] In some embodiments, more specifically, in order to further improve the quick-release capability between the rear cover 3 and the atomizer inner housing 1, a fastening opening 21 is also provided on the top of the atomizer inner housing 1, and the fastening opening 21 extends along the inner cavity of the atomizer inner housing 1.

[0030] In some embodiments, more specifically, in order to further improve the quick-release capability between the rear cover 3 and the atomizer inner housing 1, a flexible fastening plate 32 is detachably installed on the rear cover 3, and the flexible fastening plate 32 is arranged toward the fastening opening 21. When the flexible fastening plate 32 is fastened into the atomizer inner housing 1, the rear cover 3 can be positioned on the atomizer inner housing 1.

[0031] In some embodiments, in order to detect respiratory flow rate in real time based on a micro differential pressure sensor, identify the inspiratory / exhalative phase through digital filtering and threshold judgment, trigger nebulization only during the inspiratory phase, and support a pre-start / delayed shutdown compensation mechanism, a breathing valve 45 is also detachably installed in the upper channel plate 43, and the breathing valve 45 is located below the multiple sets of air inlets 44.

[0032] In some embodiments, in order to facilitate rapid charging of the breathing-synchronous nebulizer, a built-in charging port is detachably installed at the bottom of the rear cover 3, and a cover for sealing the built-in charging port is provided.

[0033] In some embodiments, in order to facilitate quick and clear observation of the remaining liquid volume inside the feeding tank 31, the feeding tank 31 is made of transparent plastic and has multiple sets of scale lines, through which the remaining liquid volume inside the feeding tank 31 can be read.

[0034] In summary, the nebulizer's built-in controller 2, employing a nebulization main control chip integrating ADC and PWM, initiates or periodically performs frequency scanning, using the peak drive current as a feedback indicator to automatically search for and lock the current optimal resonant frequency, achieving adaptive and efficient nebulization. The installed breathing valve 45, based on a miniature differential pressure sensor, detects the breathing flow rate in real time, and uses digital filtering and threshold judgment to identify the inhalation / exhalation phase, triggering nebulization only during the inhalation phase. It also supports a pre-start / delayed shutdown compensation mechanism.
