[0028] To further facilitate the use of patients, the hose interface 4 is connected to the connecting hose 3 and is connected to the breathing mask 2. The breathing mask 2 is provided with an elastic elastic band 1. The patient fixes the breathing mask 2 to the face by wearing the elastic elastic band 1 to perform atomization treatment; thus, the patient does not need to use his hands to maintain the fixed atomizer mask when in use, thereby freeing the patient's hands and solving the limitations of the existing portable atomizer usage scenarios; in addition, this embodiment is fixed to the rear side of the atomizer body 11 through a shoulder strap 9, and the tightness of both ends of the shoulder strap 9 can be adjusted. The entire atomizer can be fixed to the patient's waist or chest by hanging it around the waist or carrying it diagonally, which is further convenient for the patient to carry and completely frees his hands; in addition, the sliding cover 14 of this embodiment is fixed to the middle of the front shell 16 by a slide rail structure, and can be slid horizontally according to the arrow indication on the surface to open and close the storage bin 25. The storage bin 25 is used to store spare medicines, the breathing mask 2 and the connecting hose 3, ensuring the hygiene of the equipment while further facilitating the patient to carry it outside.

[0029] In this embodiment, a power supply 18 is fixed to the other side of the air filtration module 19, and the power supply 18 supplies power to the air module, temperature control module 20, fan 30, control module 17, electronic display screen 15 and ultrasonic module 22. The inner shell 12 and the atomizer body 11 are reserved with a USB TypeC interface 29 to charge the power supply 18; specifically, the power supply 18 provides stable power support for the control module 17, temperature control module 20, air filtration module 19, ultrasonic module 22, fan 30 and electronic display screen 15 through the internal circuit. The power supply 18 is connected to the USB TypeC interface 2929 to facilitate charging and power maintenance of the equipment.

[0030] The physical connections in this embodiment are as follows: the temperature control module 20, ultrasonic generator 31, and transducer 32 are all electrically connected to the control module 17 via wires, ensuring stable and accurate signal transmission. The electronic display 15 also communicates with the control module 17 via electrical connections, ensuring rapid response to user input. In the physical circuit design, all modules share power provided by the power supply 18. Through rational circuit routing, efficient collaboration between modules is achieved.

[0031] The program logic of this embodiment is as follows: the control program is stored in the control module 17, which sets the default parameters of each module (such as the default temperature and atomization rate) during initialization. After the user inputs information through the electronic display 15, the control module 17 adjusts the operating status of the corresponding module (such as adjusting the speed of the fan 30 and changing the operating frequency of the ultrasonic module 22) according to the preset logic algorithm.

[0032] It should be emphasized that the control relationship between the control module 17 and each module in this embodiment is the existing public content. This embodiment does not make any improvements or innovations. It is within the knowledge of those skilled in the art based on the content of the embodiment. The control relationship and connection relationship between the control module 17 and other modules are further explained below:

[0033] Relationship between control module 17 and function buttons: Control module 17 interacts with the device's physical function buttons (such as the switch button 5 and the scroll wheel 6) through electrical connections. These button interfaces convert the user's physical operation signals into digital signals for recognition and processing by control module 17.

[0034] Key function realization:

[0035] (1) Switch button 5: When the user presses the switch button 5, an on / off instruction is sent to the control module 17. The control module 17 controls the power supply 18 to be connected or disconnected according to the signal, thereby realizing the overall start / stop control of the device.

[0036] (2) Roller 6: The rotation of the roller 6 is captured by the built-in sensor and converted into a regulation signal, which is transmitted to the control module 17. The control module 17 adjusts the power output of the fan 30 according to the rotation direction and amplitude of the roller 6, thereby changing the atomization rate.

[0037] (3) Feedback mechanism: After each key operation, the control module 17 will feedback the current device status through the electronic display screen 15, including: the power supply 18 on status, current atomization rate, atomization time, air temperature, atomization countdown, atomization rate input, timed atomization, and temperature adjustment input operations, so that the user can understand the working status of the device in real time.

[0038] Relationship between control module 17 and temperature control module 20: Control module 17 controls the operating state of temperature control module 20 by receiving input instructions (such as temperature setting values) from electronic display 15. Temperature control module 20 adjusts the incoming air temperature according to the instructions of control module 17 to ensure that the mixing of air and liquid medicine achieves the best atomization effect.

[0039] The temperature control module 20 is equipped with temperature sensors for detecting the temperature of the incoming air or the temperature inside the atomization chamber in real time. These sensors send the monitored temperature data to the control module 17.

[0040] Heating element adjustment: Based on the instructions sent by the control module 17, the temperature control module 20 adjusts the output power of the internal heating element to increase or decrease the temperature of the air or the atomization chamber. The heating element of this embodiment adopts a heating wire.

[0041] Feedback control: The temperature control module 20 adopts a closed-loop feedback control system. By continuously comparing the current temperature with the target temperature, the power of the heating element is dynamically adjusted to ensure that the temperature is maintained within the set range.

[0042] Relationship between control module 17, transducer 32, and ultrasonic generator 31: Control module 17 is responsible for activating and adjusting the operating state of ultrasonic module 22. Specifically, control module 17 sends signals to ultrasonic generator 31 to activate or deactivate ultrasonic wave generation and adjusts the operating frequency and power of transducer 32 to optimize the atomized particle size of the liquid medicine.

[0043] The relationship between the control module 17 and the electronic display 15: The electronic display 15 not only displays the current operating status of the device (such as temperature and atomization rate), but also allows the user to input control commands. These input commands are transmitted to the control module 17, which interprets and executes them, enabling the user to precisely control the device.

[0044] In this embodiment, Figure 4 As shown, a water blocking piece 27 is provided at the connection between the liquid medicine chamber 33 and the mist outlet 26 to prevent the liquid medicine from spraying out.

[0045] In this embodiment, the injection port 28 is sealed by a sealing cap 8, and the hose interface 4 is sealed by a mist outlet cover 7. The liquid medicine flows into the liquid medicine chamber 33 through the injection port 28. When the atomizer is activated, the injection port 28 is sealed by the sealing cap 8. The mist outlet cover 7 can slide laterally to control the opening and closing of the mist outlet 26.

[0046] The ultrasonic generator 31 of this embodiment is also conventional technology. Its operating principle is as follows: An ultrasonic atomizer is a device that converts liquid into tiny particles using the principle of ultrasonic vibration. It primarily consists of the ultrasonic generator 31, a vibration system, an atomization chamber, and a control system. The ultrasonic vibration system is the core component of an ultrasonic atomizer, using high-frequency vibration to disperse the liquid into tiny particles and form a mist-like substance. The operating principles of an ultrasonic atomizer primarily include the principles of ultrasonic vibration, liquid atomization, and atomization effect control.

[0047] First, the principle of ultrasonic vibration is the foundation of ultrasonic atomizers' atomization. Ultrasonic waves are sound waves with frequencies exceeding 20kHz. Their high vibration frequency and short wavelength produce a strong vibration effect. The ultrasonic vibration system converts electrical energy into ultrasonic energy, which is then transmitted to the liquid through the vibration system, causing the liquid molecules to vibrate at high frequencies. This high-frequency vibration breaks down the liquid's surface tension, gradually dispersing the liquid molecules into tiny particles. Therefore, ultrasonic vibration is the key to achieving liquid atomization.

[0048] Secondly, the principle of liquid atomization is the physical process achieved by an ultrasonic atomizer. Under the influence of ultrasonic vibrations, liquid molecules are subjected to intense vibrational forces, gradually forming tiny particles. These tiny particles gradually detach from the liquid surface as the ultrasonic vibrations act, forming a mist-like substance. Due to the high frequency of ultrasonic vibrations, the liquid particles are very small, generally between 1 and 100 μm, resulting in a uniform and fine mist.

[0049] In order to further improve the air purification effect, the air filter module 19 is an activated carbon filter layer and a HEPA filter layer.
