[0002] Nebulizer is a medical device that atomizes liquid medicine into tiny particles, which are then inhaled into the respiratory tract and lungs for precipitation, achieving painless, rapid and effective treatment. Currently, nebulizers have gone through three generations. The first generation is ultrasonic nebulizers, the second generation is compression nebulizers, and the third generation is mesh nebulizers. At present, compression nebulizer technology is relatively mature and has a high cost-effectiveness, making it the mainstream product in the market. The mesh nebulizer combines the advantages of the first two nebulizers with the advantage of a small size, and is the future development trend of the medical nebulizer industry.

[0003] However, in the prior art, the atomizer sheet used in the mesh atomizer contains ceramics, and the performance of ceramics is significantly affected by temperature. Within an appropriate range, the higher the temperature, the better the performance of the ceramics, and vice versa. Therefore, the atomization rate will also change with the change of ceramic performance. In addition, the surface of the atomizer sheet is formed by laser drilling. During the atomization process, the surface of the atomizer sheet is prone to water accumulation and clogging, causing the atomization rate to fluctuate, thereby affecting the user's treatment effect. Summary of the invention

[0005] According to one aspect of an embodiment of the present application, a method for controlling an atomization rate of a mesh atomizer is provided, wherein the mesh atomizer comprises: an atomizer cup and an inductive sensing module, and the method for controlling the atomization rate comprises: obtaining a liquid level state in the atomizer cup of the atomizer; if there is liquid in the atomizer cup, when the atomizer is working, controlling the inductive sensing module to determine a current value of atomized liquid passing through a liquid outlet of the atomizer cup; and adjusting the atomization rate according to the current value of the atomized liquid at the liquid outlet of the atomizer cup.

[0006] By setting up an inductive sensing module, the current value of the atomized liquid at the outlet of the atomizer cup is obtained, the atomization rate is characterized by the current value of the atomized liquid at the outlet of the atomizer cup, and the atomization rate is adjusted by the feedback of the current value of the atomized liquid at the outlet of the atomizer cup, so that the atomization rate can be dynamically maintained, and the influence of the temperature on the atomization rate of the ceramic atomizer is reduced to a certain extent, and the surface of the atomizer is prone to water accumulation and clogging during the atomization process, which causes the atomization rate to fluctuate. The atomization rate is characterized by easy-to-handle and simple-principle features, which improves the accuracy of the atomization rate control of the mesh atomizer, reduces the difficulty of data processing, and improves the atomization efficiency of the mesh atomizer, thereby improving the user experience of the mesh atomizer and improving its practicality.

[0007] As an optional embodiment, the inductance sensing module includes: a magnetic ring arranged at the liquid outlet of the atomizer cup and a coil wound around the magnetic ring, wherein the atomized liquid flowing out of the liquid outlet of the atomizer cup passes through the inner ring of the magnetic ring; controlling the inductance sensing module to obtain the current value of the atomized liquid passing through the liquid outlet of the atomizer cup includes: determining the current value of the coil when the atomized liquid at the liquid outlet passes through the magnetic ring.

[0008] The inductive sensing module includes a magnetic ring at the liquid outlet of the atomizer cup and a coil wound around the magnetic ring. When the mesh atomizer is working, the atomized liquid passes through the inner ring of the magnetic ring, and the charged liquid passes through the center of the coil. Due to the mutual induction phenomenon, the coil generates current, and then determines the current value of the coil when the atomized liquid at the liquid outlet passes through the magnetic ring. The inductive sensing module uses a simple and low-cost setting to make the atomized liquid at the liquid outlet generate current, and then characterizes the atomization rate through the obtained current, and adjusts the atomization rate accordingly. The structure with simple principle, small volume, low cost and easy production is adopted to make the atomized liquid at the liquid outlet generate current, and then realize the dynamic maintenance of the atomization rate, further improving the user experience of the mesh atomizer and improving practicality.

[0010] Specifically, the charged liquid passes through the center of the coil. Due to the mutual inductance phenomenon, the coil will generate current to form a reverse induced electromotive force, thereby forming a current. The current directly formed at the liquid outlet of the atomizer cup is further processed by the current measurement submodule to form a current value that can be accurately identified and obtained, thereby realizing the collection of the atomization current of the atomizer cup, which can improve the accuracy of obtaining the current value at the liquid outlet of the atomizer cup, and then improve the atomization rate of the atomizer cup. The accuracy can be further improved.

[0011] As an optional implementation, adjusting the atomization rate according to the current value of the atomized liquid at the liquid outlet of the atomization cup includes: adjusting the duty cycle of the atomization rate PWM according to the current value of the atomized liquid.

[0014] The liquid level state in the atomizer cup is obtained by a water level probe. When the water level probe detects that there is liquid in the atomizer cup and the atomizer is working, the inductive sensing module is controlled to determine the current value of the atomized liquid passing through the liquid outlet of the atomizer cup, thereby improving the accuracy of the current value acquisition.

[0015] As another aspect of the present application, a mesh nebulizer is provided, comprising: a main unit and an nebulizer cup; the nebulizer cup is provided with a medicine liquid storage chamber, the medicine liquid storage chamber is provided with a liquid outlet, a spray tube is installed on the outer side of the liquid outlet, an atomizer sheet is arranged between the spray tube and the liquid outlet, the spray tube is connected with the atomizer sheet and the liquid outlet in sequence to form a medicine liquid atomization channel, characterized in that an inductance sensor module is provided on the spray tube, the inductance sensor module is electrically connected to a controller in the main unit so that the controller collects a current value in the inductance sensor module for feedback adjustment of the working frequency of the atomizer sheet.

[0016] By setting up an inductive sensing module and electrically connecting the inductive sensing module to the controller in the host, the connection between the atomizer structure and the circuit can be realized, and the characterization and processing of the current and the feedback adjustment of the atomization rate can be realized. The setting of the electrode plate integrates the transmission and conversion of the circuit into the electrode plate, which simplifies the circuit and reduces the complexity of the circuit.

[0017] As an optional implementation, the inductive sensing module is sleeved or embedded on the spray pipe and the spray particles pass through it to generate an induced current signal, and the current signal is transmitted to the controller through a current sampling circuit.

[0018] The charged liquid passes through the inductive sensor module. Due to the mutual inductance phenomenon, the coil generates current to form a reverse induced electromotive force, thereby forming a current. The current is transmitted to the controller through the current sampling circuit to process the current. The working current signal of the atomizer cup is transmitted to the current detection part, thereby realizing the structural component of current collection. The circuit structure is simple and easy to implement, reducing the process cost of the atomizer.

[0019] As an optional embodiment, a current detection probe electrically connected to the inductance sensing module is provided in the atomizer cup, and the current detection probe is connected to a current detection electrode provided on an electrode plate, and the electrode plate is provided in the host and electrically connected to the controller, so that the inductance sensing module transmits the current signal in the loop to the controller.

[0020] By connecting the current detection probe to the current detection electrode arranged on the electrode plate, the inductance sensing module can transmit the current signal in the loop to the controller, thereby further realizing the collection of the current signal, and can process the current signal, and feedback-adjust the atomization rate according to the processed current signal, thereby improving the practicality of the atomizer.

[0021] As an optional embodiment, an atomizer driving electrode and a water-free detection electrode are also provided on the electrode plate. The atomizer driving electrode is electrically connected to the atomizer through an atomizer driving probe and is used to drive the atomizer to vibrate. The water-free detection probe is arranged in the medicine storage chamber and connected to the water-free detection electrode.

[0022] The water level signal in the atomizer cup passes through the water-free detection probe, and the water-free detection probe transmits the water or water-free signal in the atomizer cup to realize the structural component of water-free sensing; at the same time, an atomizer plate driving electrode is also provided, which is electrically connected to the atomizer plate through the atomizer plate driving probe, and can drive the atomizer plate to vibrate, so that the atomizer can realize the atomization function.

[0025] The atomizer is composed of a ceramic sheet and a stainless steel sheet. Piezoelectric ceramics have the property of spontaneous polarization, and spontaneous polarization can be transformed under the action of an external electric field. Therefore, when an external electric field is applied to a piezoelectric dielectric, the piezoelectric ceramic will deform. The reason why the piezoelectric ceramic will deform is that when an external electric field equal to the spontaneous polarization is applied, the polarization intensity is enhanced. The increase in polarization intensity causes the piezoelectric ceramic sheet to stretch along the polarization direction; if a reverse electric field is applied, the ceramic sheet shortens along the polarization direction. The stainless steel sheet and the ceramic sheet are bonded together. Due to the expansion and contraction movement of the ceramic sheet, the atomizer diaphragm is driven to vibrate radially, thereby realizing the atomization operation. The structure is simple and the practicality of the atomizer is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The inductive sensing module includes a magnetic ring 3 at the liquid outlet 2 of the atomizing cup 1 and a coil 4 wound around the magnetic ring 3. When the mesh atomizer is working, the atomized liquid passes through the inner ring of the magnetic ring 3, and the charged liquid passes through the center of the coil 4. Due to the mutual induction phenomenon, the coil 4 will generate current, and then determine the current value of the coil 4 when the atomized liquid at the liquid outlet 2 passes through the magnetic ring 3.

The setting of the electrode plate 5 integrates the transmission and conversion of the circuit into the electrode plate 5, simplifies the circuit and reduces the complexity of the circuit.

[0052] As an optional implementation, the inductive sensing module is sleeved or embedded on the spray pipe and the spray particles pass through it to generate an induced current signal, and the current signal is transmitted to the controller through the current sampling circuit 12.

[0053] The charged liquid passes through the inductive sensing module.

The current passes through the current sampling circuit 12 to transmit the current signal to the controller for current processing. The working current signal of the atomizer cup is transmitted to the current detection part, thereby realizing the structural component of current collection. The circuit structure is simple and easy to implement, reducing the process cost of the atomizer.

[0060] The atomizer is composed of a ceramic sheet and a stainless steel sheet. Piezoelectric ceramics have the property of spontaneous polarization, and spontaneous polarization can be transformed under the action of an external electric field. Therefore, when an external electric field is applied to a piezoelectric dielectric, the piezoelectric ceramic will deform.
