[0002] The nebulizer is a medical device that atomizes liquid medicine into small particles, which are inhaled into the respiratory tract and lungs to achieve painless, rapid and effective treatment. Currently, the nebulizer has experienced three generations. The first generation product is an ultrasonic nebulizer, the second generation is a compression nebulizer, and the third generation is a mesh nebulizer. At present, the compression nebulizer technology is relatively mature, and the cost performance is high, which is the mainstream product in the market. The mesh nebulizer has the advantages of the previous two types of nebulizers, and has the advantage of small size, which is the development trend of the future medical nebulizer industry.

[0003] However, in the prior art, the mesh nebulizer uses an atomizing sheet composed of ceramic, and the performance of ceramic is obviously affected by temperature. Within a proper range, the higher the temperature, the better the performance of ceramic, and vice versa. Therefore, the atomization rate will change with the change of the performance of ceramic. In addition, the surface of the atomizing sheet is formed by laser drilling, and water is easy to accumulate and block the holes on the surface of the atomizing sheet during the atomization process, which affects the treatment effect of the user. SUMMARY

[0006] By setting the inductive sensing module, the current value of the atomized liquid at the atomizing cup liquid outlet is obtained, the atomization rate is characterized by the current value of the atomized liquid at the atomizing cup liquid outlet, and the atomization rate is adjusted by the current value of the atomized liquid at the atomizing cup liquid outlet. Dynamic retention of the atomization rate can be achieved, which to some extent reduces the influence of the performance of the ceramic atomizing sheet being obviously affected by temperature on the atomization rate, and also alleviates the situation that the atomizing sheet surface is easy to accumulate water and block the holes during atomization, causing the atomization rate to fluctuate. The atomization rate is characterized by using easy-to-handle and simple principle features, which improves the atomization rate control accuracy of the mesh atomizer, reduces the data processing difficulty, improves the atomization efficiency of the mesh atomizer, and thus improves the use experience of the mesh atomizer and improves the practicality.

[0016] By arranging the inductance sensing module and electrically connecting the inductance sensing module with the controller in the host, the connection of the atomizer structure and the circuit is realized, the representation of the current and the processing of the current are realized, and the feedback adjustment of the atomizing rate is realized. The arrangement of the electrode plate integrates the transmission and conversion of the circuit in the electrode plate, 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 the inductive sensing module to generate an induced current signal, and the current signal is transmitted to the controller through the current sampling circuit.

[0018] The charged liquid passes through the inductive sensing module, and due to the mutual inductance phenomenon, the coil generates a current to form a reverse induced electromotive force, thereby forming a current, and the current is transmitted to the controller through the current sampling circuit. The working current signal of the atomizing piece cup is transmitted to the current detection part, thereby realizing the structural components of current acquisition, the circuit structure is simple and easy to realize, and the process cost of the atomizer is reduced.

[0019] As an optional implementation, the atomizing cup is provided with a current detection probe electrically connected with the inductive sensing module, the current detection probe is connected with a current detection electrode arranged on an electrode plate, and the electrode plate is arranged in the main machine and electrically connected with the controller, so that the inductive sensing module transmits the current signal in the loop to the controller.

The piezoelectric ceramic has the property of spontaneous polarization, and the spontaneous polarization can be transformed under the action of an external electric field. Therefore, when an external electric field is applied to the piezoelectric medium, the piezoelectric ceramic will be deformed. The piezoelectric ceramic will be deformed because when the same external electric field as the spontaneous polarization is applied, the polarization intensity is increased. The increase of the polarization intensity makes the piezoelectric ceramic sheet elongate along the polarization direction; if a reverse electric field is applied, the ceramic sheet will shorten along the polarization direction. The stainless steel sheet and the ceramic sheet are attached together, and due to the expansion and contraction movement of the ceramic sheet, the atomizing diaphragm is driven to vibrate radially, so as to realize the atomizing operation. The structure is simple, and the practicability of the atomizer is improved. BRIEF DESCRIPTION OF DRAWINGS

[0036] As shown in Figures 1-2 To solve the above technical problems, the present application provides a method for controlling the atomization rate of a mesh atomizer, the mesh atomizer comprising an atomization cup 1 and an inductive sensing module, the method comprising:

[0037] S1, acquiring the liquid level state in the atomization cup 1 of the atomizer;

[0038] S2, if there is liquid in the atomization cup, when the atomizer is working, controlling the inductive sensing module to determine the current value of the atomized liquid through the liquid outlet 2 of the atomization cup 1;

[0039] S3, adjusting the atomization rate according to the current value of the atomized liquid through the liquid outlet 2 of the atomization cup 1.

[0040] By setting the inductance sensing module, the current value of the atomized liquid at the liquid outlet 2 of the atomizing cup 1 is obtained, the atomization rate is characterized by the current value of the atomized liquid at the liquid outlet 2 of the atomizing cup 1, and the atomization rate is adjusted by the current value of the atomized liquid at the liquid outlet 2 of the atomizing cup 1. The dynamic retention of the atomization rate can be realized, which to some extent reduces the influence of the performance of the ceramic atomizing sheet which is obviously affected by temperature on the atomization rate, and also relieves the situation that the atomizing sheet surface is easy to accumulate water and block the holes during atomization, causing the atomization rate to fluctuate. The atomization rate is characterized by using the characteristics of easy processing and simple principle, which improves the atomization rate control accuracy of the mesh atomizer, reduces the data processing difficulty, improves the atomization efficiency of the mesh atomizer, and further improves the use experience of the mesh atomizer, and improves the practicability.

[0041] As an optional implementation, the inductance sensing module includes a magnetic ring 3 arranged at the liquid outlet 2 of the atomizing cup 1 and a coil 4 wound around the magnetic ring 3, wherein the atomized liquid flowing out of the liquid outlet 2 of the atomizing cup 1 passes through the inner ring of the magnetic ring 3; the control of the inductance sensing module to obtain the current value of the atomized liquid passing through the liquid outlet 2 of the atomizing cup 1 includes determining the current value of the coil 4 when the atomized liquid of the liquid outlet 2 passes through the magnetic ring 3.

[0042] The inductance sensing module includes a magnetic ring 3 of the liquid outlet 2 of the atomizing cup 1 and a coil 4 wound around the magnetic ring 3. When the mesh atomizer works, 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 inductance phenomenon, the coil 4 will generate current, and then the current value of the coil 4 when the atomized liquid of the liquid outlet 2 passes through the magnetic ring 3 is determined. The inductance sensing module makes the atomized liquid of the liquid outlet 2 generate current by simple and low-cost setting, and then the atomization rate is characterized by the obtained current, and the atomization rate is adjusted accordingly. The structure with simple principle, small size, low cost and easy production makes the atomized liquid of the liquid outlet 2 generate current, and then realizes the dynamic retention of the atomization rate, further improves the use experience of the mesh atomizer, and improves the practicability.

[0043] Among them, for example, the coil 4 can be hot melted into the liquid outlet 2 of the atomizing cup 1 in the process of injection molding, and the two ends of the coil 4 are led out and connected with the iron ring 10 at the screw hole of the atomizing sheet 9. The screw 9 fixes the atomizing cup 1, first contacts the current detection electrode 7 which is hot melted with the atomizing sheet, and then transmits the working current signal at the liquid outlet 2 of the atomizing cup 1 to the current detection part through the contact on the adapter PCB, so as to realize the structural composition part of current acquisition

[0044] As an optional implementation, the inductance sensing module further comprises: a current measurement sub-module electrically connected with the coil 4; after obtaining the current value of the coil 4, the current measurement sub-module is controlled to process the current value of the coil 4.

[0045] Specifically, the charged liquid passes through the center of the coil 4, and due to the mutual inductance phenomenon, the coil 4 generates a current to form a reverse induced electromotive force, thereby forming a current. The current directly formed by the liquid outlet 2 of the atomizing cup 1 is further processed by the current measurement sub-module to form a current value that can be accurately identified and obtained, thereby realizing the collection of the atomizing current of the atomizing cup 1, improving the accuracy of obtaining the current value of the liquid outlet 2 of the atomizing cup 1, and further improving the adjustment of the atomization rate of the atomizing cup 1, thereby further improving the accuracy of the atomization rate of the mesh atomizer.

[0046] As an optional implementation, the adjustment of the atomization rate according to the current value of the atomized liquid of the liquid outlet 2 of the atomizing cup 1 comprises: adjusting the duty cycle of the atomization rate PWM according to the current value of the atomized liquid.

[0047] By adjusting the duty cycle of the atomization rate PWM, the effect of keeping the atomization rate constant is realized, and the accuracy of the atomization rate of the mesh atomizer is further improved.

[0048] As an optional implementation, the mesh atomizer comprises a water level monitoring module, and the water level monitoring module comprises a water level probe arranged in the atomizing cup 1; the obtaining of the liquid level state in the atomizing cup 1 of the mesh atomizer comprises: controlling the water level probe to obtain the liquid level state in the atomizing cup 1.

[0049] The liquid level state in the atomizing cup 1 is obtained by the water level probe. When the water level probe obtains that there is liquid in the atomizing cup 1 and the mesh atomizer is working, the inductance sensing module is controlled to determine the current value of the atomized liquid passing through the liquid outlet 2 of the atomizing cup 1, thereby improving the accuracy of obtaining the current value.

[0050] As another aspect of the present application, a mesh atomizer is provided, comprising: a host, an atomizing cup 1; the atomizing cup 1 is provided with a liquid medicine storage cavity, the liquid medicine storage cavity is provided with a liquid outlet 2, the outer side of the liquid outlet 2 is provided with a spray pipe, the spray pipe and the liquid outlet 2 are provided with an atomizing sheet therebetween, and the spray pipe is in communication with the atomizing sheet and the liquid outlet 2 in sequence to form a liquid medicine atomization channel, characterized in that the spray pipe is provided with an inductance sensing module, the inductance sensing module is electrically connected with a controller in the host to enable the controller to collect the current value in the inductance sensing module, and is used for feedback adjustment of the working frequency of the atomizing sheet.

[0051] By setting the inductive sensing module and making the inductive sensing module electrically connected with the host controller, the connection of the atomizer structure and the circuit can be realized, the current representation and the current processing can be realized, and the feedback adjustment of the atomization rate can be realized. The setting of the electrode plate 5 integrates the transmission and conversion of the circuit in 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 through which the spray particles pass 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, and due to the mutual inductance phenomenon, the coil 4 generates a current to form a reverse induced electromotive force, thereby forming a current. The current is transmitted to the controller through the current sampling circuit 12, and the current is processed. The working current signal of the atomizing piece cup is transmitted to the current detection part, thereby realizing the structural components of current acquisition. The circuit structure is simple and easy to realize, and the process cost of the atomizer is reduced.

[0054] As an optional implementation, the atomizing cup 1 is provided with a current detection probe electrically connected with the inductive sensing module. The current detection probe is connected with the current detection electrode 7 provided on the electrode plate 5. The electrode plate 5 is provided in the host and is electrically connected with the controller, so that the inductive sensing module transmits the current signal in the loop to the controller.

[0055] By connecting the current detection probe with the current detection electrode 7 provided on the electrode plate 5, the inductive sensing module can transmit the current signal in the loop to the controller, thereby further realizing the acquisition of the current signal, and the current signal can be processed, and the atomization rate can be feedback adjusted according to the processed current signal, thereby improving the practicability of the atomizer.

[0056] As an optional implementation, the electrode plate 5 is further provided with an atomizing piece driving electrode 6 and a waterless detection electrode 8. The atomizing piece driving electrode 6 is electrically connected with the atomizing piece through an atomizing piece driving probe, and is used for driving the atomizing piece to vibrate. The waterless detection probe is provided in the liquid storage cavity and is connected with the waterless detection electrode 8.

[0057] The water level signal in the atomizing cup 1 is transmitted by the waterless detection probe. The water or waterless signal in the atomizing cup 1 is transmitted by the waterless detection probe, thereby realizing the structural components of waterless induction. Meanwhile, the atomizing piece driving electrode 6 is provided, which is electrically connected with the atomizing piece through the atomizing piece driving probe, and can drive the atomizing piece to vibrate, so that the atomizer realizes the atomization function. The circuit structure is simple and easy to realize, the process cost of the atomizer is reduced, and the intelligent degree of the atomizer is improved.

[0058] As an optional implementation, the inductive sensing module includes: a magnetic ring 3 disposed on the spray pipe, a coil 4 wound around the magnetic ring 3, and a current probe contact connected to the coil 4, wherein the probe contact is connected to the current detection probe.

[0059] As an optional implementation, the atomizing plate includes an atomizing plate driving contact and a ceramic plate and a stainless steel plate stacked together; the ceramic plate is annular and the stainless steel plate is circular.

[0060] The atomizing plate is composed of a ceramic plate and a stainless steel plate. Piezoelectric ceramics possess spontaneous polarization properties, which can change under the influence of an external electric field. Therefore, when an external electric field is applied to a piezoelectric dielectric, the piezoelectric ceramic will deform. This deformation occurs because applying an external electric field identical to the spontaneous polarization effectively enhances the polarization intensity. This increased polarization intensity causes the piezoelectric ceramic plate to elongate along the polarization direction; conversely, applying a reverse electric field causes the ceramic plate to shorten along the polarization direction. The stainless steel and ceramic plates are bonded together, and the expansion and contraction of the ceramic plate drives the atomizing diaphragm to vibrate radially, thus achieving atomization. The structure is simple, improving the practicality of the atomizer.

[0061] like Figure 4 The schematic diagram shown includes a microcontroller 11 and a current sampling circuit 12. For example, a power conversion module can be included to convert external power into system power, providing power to the microcontroller 11 system. A DC-DC power chip sets the first-stage voltage of the circuit to approximately 13.5V, and then a BOOST boost circuit, along with an inductor and capacitor, boosts the system voltage to approximately VPP50V. After the atomizer is powered on, the input terminal of the current sampling circuit contacts the stainless steel plate through the atomizer driving electrode 6 (the stainless steel portion carries a charge; after passing through the liquid, it reaches the water level probe, which detects the signal, indicating the presence of liquid and indicating a non-waterless state). The output terminal contacts the atomizer driving electrode 6. When the atomizing unit is working, the liquid in the atomizing cup 1 becomes charged. After the liquid is atomized, it forms an atomized airflow that passes through the magnetic ring 3 and coil 4 at the liquid outlet 2 of the atomizing cup 1. Due to mutual inductance, the coil 4 generates a current, which forms a reverse induced electromotive force. The current passes through the current detection electrode 7 and can be processed and output by the current sensor CC6920. The voltage is collected by the AD sampling section to determine the magnitude of the current of the liquid atomized out of the atomizing cup 1. The feedback adjustment control unit is set to adjust the duty cycle of the atomization rate PWM, thereby changing the peak-to-peak value of the current sampling circuit output terminal, thus realizing closed-loop control and achieving a stable atomization process.
