Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mesh nebulizers, and in particular to a mesh nebulizer and a temperature control system thereof. BACKGROUND

[0002] A nebulizer is a device that converts liquid substances into fine mist particles using mechanical or electronic technology. Its working principle involves vibration, ultrasonic wave action, or the application of heating elements to facilitate the breakdown of liquid into extremely fine droplets and their uniform release into the air through nozzles or mesh structures, resulting in the desired nebulization effect. The human body can achieve rapid, painless, and efficient treatment by inhaling the drug, which directly acts on the respiratory tract and lungs, and accelerates drug absorption through capillaries.

[0003] Nebulizers have a long history of application in the medical field, and their development has gone through three generations. Although the first generation of ultrasonic nebulizer technology is mature, it still faces the problem of insufficient particle size control accuracy in precise drug delivery. The second generation of compressed nebulizers, as the current market mainstream, still face challenges in noise level and size. In contrast, the third generation of mesh nebulizers quickly gained market favor due to their high efficiency, low noise, and uniform distribution of nebulized particles. However, when mesh nebulizers operate at low temperatures, the intermolecular tension of water molecules increases with decreasing temperature, and the working efficiency of ceramic sheets decreases at low temperatures, which can lead to a decrease in nebulization efficiency and affect their use.

[0054] A liquid detection module 8 is configured to detect whether the liquid is present in the mesh atomizer.

[0055] The controller module 7 is electrically connected with the driving module 4, the heating module 6, the atomization sheet temperature sensor 5 and the ambient temperature sensor 9 respectively, and is configured to receive the temperature data of the atomization sheet temperature sensor 5 and the ambient temperature sensor 9, and to perform feedback control on the heating module 6 to heat and warm up the atomization sheet 3 based on the temperature data.

[0056] The controller module 7 is electrically connected with the liquid detection module 8, and is configured to receive the detection data of the liquid detection module 8, and to control the driving module 4, the heating module 6, the atomization sheet temperature sensor 5, the ambient temperature sensor 9 and the liquid detection module 8 based on the detection data.

[0057] As shown in Figure 2 , the driving module 4 includes a boost circuit module 41 and an oscillation circuit module 42, and the boost circuit module 41 and the oscillation circuit module 42 are electrically connected; the controller module 7 generates a PWM1 waveform and inputs the PWM1 waveform into the boost circuit module 41; the controller module 7 generates a PWM2 waveform and inputs the PWM2 waveform into the oscillation circuit module 42; an AN1 pin of the controller module 7 is connected to the boost circuit module 41 to monitor the voltage of the boost circuit module 41.

[0058] As shown in Figure 3 , in the embodiment of the present application, one end of the atomization sheet temperature sensor 5 is connected to one end of an atomization resistor R25, the other end of the atomization resistor R25 is connected to a VDD pin (power voltage) of the controller module 7, one end of the atomization sheet temperature sensor 5 is connected to a PB3 pin of the controller module 7 to transmit ambient temperature data to the controller module 7, and the other end of the atomization sheet temperature sensor 5 is connected to an AN5 pin of the controller module 7. The controller module 7 outputs a power voltage through the VDD pin.

[0059] One end of the ambient temperature sensor 9 is connected to one end of an ambient resistor R26, the other end of the ambient resistor R26 is connected to a VDD pin of the controller module 7, one end of the ambient temperature sensor 9 is connected to a PB3 pin of the controller module 7 to transmit atomization sheet 3 temperature data to the controller module 7, and the other end of the ambient temperature sensor 9 is connected to a PB2 pin of the controller module 7.

[0060] The heating module 6 is grounded at one end, and the other end of the heating module 6 is connected with one end of the heating resistor R27, the other end of the heating resistor R27 is connected with the PB5 pin of the controller module 7, the other end of the heating module 6 is connected with the source of the MOS transistor Q6, the gate of the MOS transistor Q6 is connected with the PB5 pin of the controller module 7, and the drain of the MOS transistor Q6 is connected with the VDD pin of the controller module 7.

[0061] In one specific example, referring to Figure 3 , the controller module 7 adopts FT61F143 single-chip microcomputer, and the atomizing sheet temperature sensor 5 and the environment temperature sensor 9 both adopt GX0011 temperature sensor.

[0062] Figure 4 The working flow chart of the temperature control system provided by the embodiment of the application includes the following steps:

[0063] Step 1, detecting the environment temperature of the mesh atomizer based on the environment temperature sensor 9 to obtain the environment temperature.

[0064] The environment temperature of the mesh atomizer currently working can be obtained, which provides basic data (environment temperature) for subsequent temperature control.

[0065] The environment temperature sensor 9 (such as DS18B20 digital temperature sensor) integrated in the host 2 is used to collect and transmit the environment temperature data to the controller module 7 in real time.

[0066] Step 2, comparing the environment temperature with the preset environment temperature threshold value, and controlling the heating module 6 to work when the environment temperature is less than the environment temperature threshold value.

[0067] The heating module 6 can be controlled to work to increase the temperature of the atomizing sheet 3 in a low-temperature environment (the environment temperature is less than the preset environment temperature threshold value).

[0068] An environment temperature threshold value (such as 20℃) is preset in the controller module 7, and when the detected environment temperature is lower than the environment temperature threshold value, the heating module 6 is started to heat the atomizing sheet 3.

[0069] Step 3, detecting the temperature of the atomizing sheet 3 based on the atomizing sheet temperature sensor 5 to obtain the temperature of the atomizing sheet 3.

[0070] The working temperature of the atomizing sheet 3 can be directly monitored, which provides basic data (the temperature of the atomizing sheet 3) for subsequent temperature control, so as to ensure the atomizing effect and avoid damage of the atomizing sheet 3 caused by overheating to a certain extent.

[0071] Step 4, comparing the temperature of the atomizing sheet 3 with the preset atomizing sheet 3 temperature threshold value to control the heating efficiency of the heating module 6 until the mesh atomizer stops working.

[0072] The specific steps are described in detail by steps 41 to 44.

[0073] Step 41, compare the atomizing sheet 3 temperature with the atomizing sheet 3 temperature threshold value.

[0074] The atomizing sheet 3 temperature is compared with the preset atomizing sheet 3 temperature threshold value to determine the working state of the heating module 6, providing theoretical data for subsequent heating efficiency adjustment of the heating module 6.

[0075] Step 42, when the atomizing sheet 3 temperature is less than the atomizing sheet 3 temperature threshold value, increase the heating efficiency of the heating module 6.

[0076] When the atomizing sheet 3 temperature is lower than the atomizing sheet 3 temperature threshold value, the heating efficiency is increased to quickly raise the atomizing sheet 3 temperature to the atomizing sheet 3 temperature threshold value.

[0077] Step 43, when the atomizing sheet 3 temperature is greater than or equal to the atomizing sheet 3 temperature threshold value, reduce the heating efficiency of the heating module 6.

[0078] When the atomizing sheet 3 temperature reaches or exceeds the atomizing sheet 3 temperature threshold value, the heating efficiency is reduced to prevent the atomizing sheet 3 from overheating.

[0079] Step 44, determine whether the mesh nebulizer has finished nebulizing based on the preset determination condition; wherein the determination condition includes at least one of the following: the mesh nebulizer reaches a preset working time, there is no liquid medicine left in the mesh nebulizer.

[0080] According to the preset determination condition, it is determined whether the mesh nebulizer should stop working, and the running state of the mesh nebulizer is controlled accordingly.

[0081] If yes, the mesh nebulizer stops working.

[0082] If no, the temperature of the atomizing sheet 3 is detected based on the atomizing sheet temperature sensor 5, and the atomizing sheet 3 temperature is compared with the atomizing sheet 3 temperature threshold value to control the heating efficiency of the heating module 6 until the mesh nebulizer stops working.

[0083] At least one determination condition is preset in the controller module 7 to determine whether the nebulization process is finished. These determination conditions include but are not limited to: the mesh nebulizer has been continuously working for a preset upper limit of working time (such as 30 minutes, which is set by human or default value); the liquid medicine in the mesh nebulizer has been completely consumed (monitored by the liquid medicine detection sensor). When any determination condition is met, the controller module 7 issues an instruction to control the mesh nebulizer to automatically stop working, including turning off the heating module 6 and stopping the liquid medicine delivery. If the stop condition is not met, the controller module 7 repeatedly executes steps 3 to 4, continuously monitors the atomizing sheet 3 temperature and dynamically adjusts the heating efficiency, realizes the temperature control of the mesh nebulizer, makes the atomizing sheet 3 dynamically constant temperature, until the stop condition is met.

[0084] In one example, the ambient temperature threshold is set to 20℃, the atomization piece 3 temperature threshold is set to 40℃, and the preset working time is 30 minutes. The ambient temperature sensor 9 module collects ambient temperature data every 1 second and sends it to the controller module 7. The controller module 7 determines whether the ambient temperature is lower than 20℃. If yes, the heating module 6 is started to raise the ambient temperature to above 20℃; if no, the heating module 6 remains off or maintains the current heating state. The atomization piece temperature sensor 5 module reports the atomization piece 3 temperature to the controller module 7 every 0.5 seconds. The controller module 7 dynamically adjusts the heating efficiency of the heating module 6 according to the comparison result of the atomization piece 3 temperature and the 40℃ threshold. Specifically, if the atomization piece 3 temperature is lower than 40℃, the heating efficiency is increased to increase the atomization piece 3 temperature. If the atomization piece 3 temperature reaches or exceeds 40℃, the heating efficiency is reduced to avoid overheating. The controller module 7 simultaneously monitors the ambient temperature, the atomization piece 3 temperature, and the working time. When any of the following conditions is met, the atomization process is determined to be completed: the working time reaches the preset 30 minutes. The liquid detection module 8 detects that the liquid in the liquid storage compartment is exhausted. If the atomization is completed, the controller module 7 sends a command to stop the working of the heating module 6 and the driving module 4, and turns off the system power. If the atomization is not completed, steps 3 to 4 are repeatedly executed to continuously monitor and adjust the heating efficiency until the atomization is completed.

[0085] Before monitoring and adjusting the atomization piece 3 temperature of the mesh atomizer, the mesh atomizer needs to be started according to the preset starting program, which includes the following steps:

[0086] A1, output PWM1 to the boost circuit module 41 to realize the boost function, and monitor the voltage of the boost circuit module 41 through the AN1 pin to obtain the boost voltage.

[0087] A2, adjust the duty cycle of PWM2 based on the boost voltage, and output the adjusted PWM2 to the oscillation circuit module 42 to determine the working frequency of the atomization piece 3.

[0088] In one example, controller module 7 is configured to generate a PWM1 signal every 1 millisecond via the PWM output pin, with an initial duty cycle of 50% and a frequency of 50kHz, to ensure stable operation of the boost circuit and provide the required output voltage. The AN1 pin is connected to the output of boost circuit module 41 via a resistor divider module to monitor the actual output voltage of boost circuit module 41. Controller module 7 contains a voltage-frequency mapping table, which corresponds to different PWM2 frequencies based on the voltage range of boost circuit module 41. For example, when the boost voltage is 12V, the corresponding PWM2 frequency is 100kHz; while when the boost voltage is 15V, the PWM2 frequency is adjusted to 80kHz. Controller module 7 outputs the adjusted PWM2 signal via another PWM output pin. Upon receiving the PWM2 signal, oscillation circuit module 42 generates an oscillation signal to drive the atomizing plate 3 via an oscillator.

[0089] A mesh atomizer, its structure is as follows Figures 5 to 11 As shown, it includes:

[0090] Atomizer cup 1 and main unit 2.

[0091] like Figure 5 As shown, the atomizing cup 1 is provided with a medicine storage chamber 19, the medicine storage chamber 19 is provided with a liquid outlet 20, a spray pipe 21 is installed on the outside of the liquid outlet 20, an atomizing plate 3 is provided between the spray pipe 21 and the liquid outlet 20, and the spray pipe 21 is connected to the atomizing plate 3 and the liquid outlet 20 in sequence to form a medicine atomization channel.

[0092] like Figure 7 As shown, the atomizing cup 1 is also equipped with a heating probe 12, an atomizing plate temperature sensing probe 10, an atomizing plate driving probe 11, and a medicine detection probe 13 that are in contact with and connected to the atomizing plate 3.

[0093] Reference Figure 7 The atomizing plate temperature sensing probe 10 and the heating probe 12 are arranged on both sides of the atomizing plate 3. This arrangement can avoid or reduce the direct influence of the heating module 6 in the heating probe 12 on the atomizing plate temperature sensor 5 in the atomizing plate temperature sensing probe 10 to a certain extent, so that the atomizing plate temperature sensor 5 can accurately detect the temperature of the atomizing plate 3.

[0094] and Figure 7 Correspondingly, such as Figure 6 As shown, the atomizing plate temperature sensing probe contact plate 15 and the heating probe contact plate 17 are disposed on both sides of the atomizing plate 3. The atomizing plate temperature sensing probe 10 is connected to the atomizing plate temperature sensing probe contact plate 15, and the heating probe 12 is connected to the heating probe contact plate 17.

[0095] If the atomization piece temperature sensing probe 10 is arranged too close to the heating probe 12, the heat released by the heating probe 12 does not heat the atomization piece 3 to the predetermined temperature, and the atomization piece temperature sensor 5 has detected the predetermined temperature, which will affect the temperature identification of the atomization piece 3 by the atomization piece temperature sensor 5, and further affect the adjustment of the heating module 6 by the controller module 7.

[0096] Referring to Figures 8 to 10 , the PCB adapter plate 14 is arranged in the host 2, and the PCB adapter plate 14 connects the heating probe 12, the atomization piece temperature sensing probe 10, the atomization piece driving probe 11, and the liquid medicine detection probe 13 with the host 2.

[0097] Referring to Figure 11 , the host 2 is provided with the driving module 4, the atomization piece temperature sensor 5, the heating module 6, and the liquid medicine detection module 8.

[0099] In an embodiment of the present application, the atomization cup 1 and the host 2 are detachably connected, so as to facilitate the cleaning and replacement of the atomization cup 1.

[0100] Figure 6 For Figure 5 , the liquid medicine detection probe contact plate 18 is arranged in the atomization cup 1, and the liquid medicine detection probe contact plate 18 is arranged on one side of the atomization cup 1 and used to contact the liquid medicine detection probe 13. Figure 6 As shown in

[0101] , the atomization cup 1 is provided with the heating probe contact plate 17, the atomization piece temperature sensing probe contact plate 15, and the atomization piece driving probe contact plate 16. Figure 5 As shown in

[0102] , the heating probe 12 is connected in contact with the atomization piece 3 through the heating probe contact plate 17; the atomization piece temperature sensing probe 10 is connected in contact with the atomization piece 3 through the atomization piece temperature sensing probe 10; the atomization piece driving probe 11 is connected in contact with the atomization piece 3 through the atomization piece driving probe contact plate 16; and the liquid medicine detection probe 13 is connected in contact with the liquid medicine detection probe contact plate 18. Figure 11

[0103] ​In one embodiment of this application, the heating probe contact plate 17, the atomizing sheet temperature sensing probe contact plate 15, and the atomizing sheet driving probe contact plate 16 are all flexible FPCs. The flexible FPCs can, to a certain extent, prevent poor contact between the heating probe 12 and the heating probe contact plate 17 when the atomizing sheet 3 is working, thereby enabling the heating probe 12 to effectively heat the atomizing sheet 3.

[0104] The flexible FPC setting can, to some extent, avoid poor contact between the atomizing plate temperature sensing probe 10 and the atomizing plate temperature sensing probe contact plate 15, thereby enabling the atomizing plate temperature sensor 5 to accurately measure the temperature of the atomizing plate 3.

[0105] The flexible FPC setting can, to some extent, avoid poor contact between the atomizing plate drive probe 11 and the atomizing plate drive probe contact plate 16, so that when the drive module 4 drives the atomizing plate 3 to vibrate, the drive probe and the atomizing plate 3 are tightly connected.

[0106] In one embodiment of this application, the heating module 6 is a PTC thermistor, such as... Figure 3 As shown, the PTC thermistor has a built-in high-temperature limiting function, which can prevent the atomizing plate 3 from overheating to a certain extent. Combined with the control of the controller module 7, the ambient temperature sensor 9 and the atomizing plate temperature sensor 5, it can provide dual protection for the heating process of the atomizing plate 3, so as to ensure the safe heating of the atomizing plate 3 in low-temperature environments.

[0107] In specific examples, such as Figure 12 As shown, 99 atomizers with temperature compensation and 99 atomizers without temperature compensation were used to test the atomization rate of existing products. At an ambient temperature of 10°C, the atomization rate of the mesh atomizer with the embodiment of this application was higher than that of the mesh atomizer without the embodiment of this application. The vertical axis of the figure represents the atomization rate, and the horizontal axis represents the sample atomizer number.

[0108] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
