[0002] The salt aerosol therapeutic apparatus is mainly used for treating respiratory diseases. Its main function is to convert the saline spray into tiny particle gas, so that it can penetrate into the tiny parts of the respiratory tract, thus achieving the therapeutic effect. The working principle of the salt aerosol therapeutic apparatus is to atomize and evaporate the saline by using the salt aerosol generating device to generate salt aerosol, and then spray it into the respiratory tract of the patient through a special nozzle. These tiny particle gases can penetrate into the tiny parts of the respiratory tract, including the trachea, bronchi, alveoli, etc., so as to play the roles of cleaning the respiratory tract, diluting sputum, relieving inflammation, etc.

Even so, the solution with such a concentration can only generate salt mist with a concentration range close to each other in the salt aerosol generating device. Not only is the concentration controllability poor and the concentration control accuracy low, but also every time the salt mist concentration needs to be changed, it is necessary to additionally mix the solution concentration and replace the solution bottle with a suitable concentration, and the process is very cumbersome.

[0038] The salt aerosol therapeutic apparatus is used to treat respiratory diseases. Its main function is to convert saline spray into tiny particle gas, enabling it to penetrate deep into the tiny parts of the respiratory tract, thereby achieving the therapeutic effect. The working principle of the salt aerosol therapeutic apparatus is to use a salt aerosol generating device to atomize and evaporate the saline to generate salt aerosol, and then spray it into the patient's respiratory tract through a special nozzle. These tiny particle gases can penetrate deep into the tiny parts of the respiratory tract, including the trachea, bronchi, alveoli, etc., thus playing roles such as cleaning the respiratory tract, diluting phlegm, and relieving inflammation.

[0039] Currently, the concentration of salt mist can only be controlled by controlling the concentration of the solution. Even so, the solution of this concentration can only generate salt mist with a concentration range close to it in the salt aerosol generating device. Not only is the concentration controllability poor and the concentration control accuracy low, but also every time the salt mist concentration needs to be changed, it is necessary to additionally prepare the solution concentration and replace the solution bottle with the appropriate concentration, and the process is very cumbersome.

[0040] Therefore, in order to achieve controllability of the salt mist concentration, improve the control accuracy of the salt mist concentration, and simplify the concentration adjustment method, this embodiment provides a salt aerosol generating device.

[0041] As Figures 1 to 8 shown, the salt aerosol generating device includes a salt mist generating module 1, a concentration control module 2, a liquid supply module 3, a air supply module 4, a heating module 5 and a duct module 6;

[0042] The salt mist generating module 1 includes a connection line 11 and an atomization unit 12. The connection line 11 is used to connect the atomization unit 12 and the concentration control module 2. The atomization unit 12 is an atomization sheet that performs ultrasonic vibration. The atomization sheet breaks up the salt solution through ultrasonic vibration to obtain salt mist. Both the concentration control module 2 and the liquid supply module 3 are connected to the salt mist generating module 1. The concentration control module 2 is used to monitor the concentration of the salt mist in real time and adjust the vibration frequency of the atomization sheet at any time. The liquid supply module 3 is used to provide the salt solution for generating salt mist. Both the salt mist generating module 1 and the air supply module 4 are connected to the duct module 6. The heating module 5 is connected between the air supply module 4 and the duct module 6. The heating module 5 is used to heat the air blown into the duct module 6 by the air supply module 4, thereby evaporating the salt mist to obtain salt aerosol.

[0043] By setting a concentration control module 2 in the salt aerosol generating device, the concentration of the wet salt mist generated by the salt mist generating module 1 is monitored in real time, and the vibration frequency of the atomizing sheet is adjusted accordingly, so as to realize the regulation of the salt mist concentration, obtain a salt mist with a specific concentration, which has high controllability and accurate control accuracy. And the salt solution is dispersed by the ultrasonic vibration of the atomizing sheet to obtain the salt mist, so that there is no need to additionally prepare the solution concentration and replace the solution bottle 32, which simplifies the operation.

[0044] In this embodiment, in order to better control the vibration frequency of the atomizing sheet, the atomizing unit 12 has a built-in atomizing program and outputs a fixed PWM (Pulse Width Modulation) wave to control the atomizing sheet to perform ultrasonic vibration.

[0045] Specifically, as Figure 3 shown, the atomizing sheet includes a piezoelectric ceramic sheet 121 and a stainless steel sheet 122. The piezoelectric ceramic sheet 121 is connected to the concentration control module 2 through a connection line 11. The stainless steel sheet 122 is connected to the piezoelectric ceramic sheet 121 and vibrates with the vibration of the piezoelectric ceramic sheet 121.

[0046] Optionally, as Figure 4 shown, the concentration control module 2 includes a control unit 21 and a detection unit 22. The detection unit 22 is used to detect the concentration of the salt mist and feedback it to the control unit 21. The control unit 21 is used to control the vibration frequency of the atomizing sheet of the atomizing unit 12 according to the concentration information fed back by the detection unit 22. Through the mutual cooperation of the detection unit 22 and the control unit 21, the salt mist concentration is monitored and adjusted in real time, so as to ensure the concentration of the required salt mist.

[0047] Furthermore, as Figure 5 shown, the control unit 21 includes an industrial control board 211 and a voltage regulating circuit 212. The voltage regulating circuit 212 is used to connect the industrial control board 211 to the connection line 11 and output voltage to the atomizing unit 12. The industrial control board 211 is used to control the voltage output by the voltage regulating circuit 212 to the atomizing unit 12. In this way, the voltage on the atomizing unit 12 is controlled. In this embodiment, through the chip pins of the industrial control board 211, using the I2C communication protocol, the voltage output to the atomizing unit 12 is controlled according to the voltage regulating circuit 212. At the same time, the function start and stop of the atomizing unit 12 are controlled by using the pins. When the atomizing unit 12 is turned on and there is an input voltage, the atomizing sheet will change the vibration frequency according to different input voltages, so as to realize the adjustment of different atomizing amounts.

[0048] Even further, as Figure 6As shown, the voltage regulating circuit 212 includes a buck chip 2121 and a digital potentiometer 2122. The industrial control board 211 is used to control the resistance value of the digital potentiometer 2122, and the digital potentiometer 2122 is used to change the voltage output by the buck chip 2121. By controlling the digital potentiometer 2122 with the industrial control board 211, changing the resistance value, and changing the voltage output of the buck chip 2121, the voltage output to the atomization unit 12 is adjusted, thereby realizing the adjustment of the vibration frequency of the atomization sheet. In this embodiment, the model of the buck chip 2121 is AP2955, and the model of the digital potentiometer 2122 is MCP4017-104E / LT.

[0049] Optionally, as Figure 7 shown, the detection unit 22 includes a concentration sensor 221 and a transmitter 222. The concentration sensor 221 is connected to the transmitter 222 and is used to detect the concentration of the salt mist, and the transmitter 222 is used to send the concentration information to the control unit 21. By setting the concentration sensor 221, the concentration of the salt mist is detected, and by setting the transmitter 222, it is convenient to timely feedback the concentration information of the salt mist to the control unit 21.

[0050] Optionally, as Figure 8 shown, the liquid supply module 3 includes a liquid filling device 31, a solution bottle 32 and a piercer 33. A salt solution is provided in the solution bottle 32. The solution bottle 32 is connected to the liquid filling device 31, and the liquid filling device 31 is used to drive the solution bottle 32 to approach or move away from the piercer 33, so that the piercer 33 pierces the solution bottle 32 and transports the salt solution to the salt mist generating module 1. By setting the liquid filling device 31 and the piercer 33, it is convenient to drive the solution bottle 32 to move, and by moving the solution bottle 32, the solution bottle 32 is pierced by the piercer 33, eliminating the need for an operator to pierce the solution bottle 32 separately outside, simplifying the liquid supply operation.

[0051] Optionally, the air supply module 4 is a blower, and the heating module 5 is a thermite heating sheet arranged at the air outlet of the blower. By placing the heating module 5 at the air outlet of the blower, heated air is input into the air duct module 6, so that the heated air heats the moist salt mist in the air duct module 6, thereby realizing the evaporation of the salt mist. The thermite heating sheet is adopted, which has the characteristics of rapid heating, environmental protection, health, strong durability, high efficiency, automatic constant temperature, safety and reliability, and energy saving.

[0052] In this embodiment, a salt aerosol therapeutic apparatus is further provided. The salt aerosol therapeutic apparatus includes the above-mentioned salt aerosol generating device.
