[0019] like Figures 1-4As shown, this utility model provides a gas compression device with flexible selection and setting time, characterized in that it includes: a housing 10, a compressed air pump 11 fixedly installed inside the housing 10, a first air outlet 12 on the top of the housing 10, and a second air outlet 13 on the top of the compressed air pump 11. The first outlet and the second outlet 13 are connected by a pipe. A control board 14 is also installed inside the housing 10 and at the bottom of the compressed air pump 11. The control board 14 integrates a timing control circuit 15 and a microprocessor 17. The timing control circuit 15 includes: a DC_IN interface, a capacitor C1, a resistor R1, and an MO switch. The DC_IN interface is used to connect to a 5V 2A external power supply. The capacitor C1 and the resistor R1 are connected in series between the DC_IN interface and the input terminal of the MO switch. The output terminal of the switch is connected to the microprocessor 17. The housing 10 is also provided with a control button 16, which is connected to the microprocessor 17 and is used to adjust a set time. The microprocessor 17 is also connected to the compressed air pump 11 and is used to control the start and stop of the compressed air pump 11. Specifically, a compressed air pump 11 is fixedly installed inside the outer casing 10. This compressed air pump 11 is used to provide compressed gas. The top of the compressed air pump 11 is provided with a second air outlet 13, and the top of the outer casing 10 is provided with a first air outlet 12. The first air outlet 12 and the second air outlet 13 are connected together by a pipe. The compressed air pump 11 is preferably a miniature brushless air pump. A rubber shock-absorbing pad can be provided between its outer periphery and the inner wall of the outer casing 10. The first air outlet 12 is also connected to an external atomizing cup through a pipe so that the compressed gas can be delivered to the atomizing cup for atomization. The atomization principle is that the compressed air pump 11 generates a high-pressure airflow, which is delivered to the atomizing cup through the pipe. A nozzle or guide structure can be set in the atomizing cup to form a high-speed airflow jet, which produces a shearing and tearing effect on the liquid medicine in the atomizing cup, so that the originally liquid liquid medicine is dispersed into particles with a diameter of 5-10 μm. The nebulizer produces tiny droplets, forming a medicinal mist, which is then inhaled by the patient through a mouthpiece or mask to achieve a therapeutic effect. This is a conventional technique, and the actual assembly can refer to existing technologies; therefore, the structure of the nebulizer cup will not be described in detail here. A control board 14 is also located at the bottom of the compressed air pump 11. This control board 14 integrates a timing control circuit 15 and a microprocessor 17. The timing control circuit 15 is used to control the working time of the compressed air pump 11. It includes: a DC_IN interface, a capacitor C1, a resistor R1, and an MO switch. The DC_IN interface is used to connect to a 5V 2A external power supply. The capacitor C1 and resistor R1 are connected in series between the DC_IN interface and the input terminal of the MO switch. The output terminal of the MO switch is connected to the microprocessor 17. The compressed air pump 11 is also connected to the microprocessor 17 so that the microprocessor 17 can control the start and stop of the compressed air pump 11. The DC_IN interface... An external 5V / 2A power supply is connected to the interface. After being filtered and regulated by capacitor C1 and current-limited by resistor R1, a stable 5V / 1.7A current is output through the MO switch. Control buttons 16 are also provided on the outer casing 10. The primary control buttons 16 include time increment and time decrement buttons, which are electrically connected to the microprocessor 17 for adding or subtracting time. It should be noted that the time increment / decrement buttons can also be used to wake up the system; pressing either button will wake the circuit system to set the time. When the button is not pressed for a long time, the system enters a sleep state. A power button can also be added for turning the system on or off, depending on the actual usage requirements. During use, the setting mode can be entered through control buttons 16, and the corresponding time can be set according to the initial nebulization time of the medication. Time can be added or subtracted using the time increment and decrement buttons. After confirmation, the microprocessor 17 receives a confirmation signal and controls the MO switch to close, providing 5V / 1.7A.A 7A power supply drives the compressed air pump 11 to start. When the running time reaches the set value, the microprocessor 17 controls the MO switch to open, and the compressed air pump 11 stops working and enters a standby state. This method allows for setting corresponding nebulization times according to different medications, without restrictions, providing greater flexibility. Furthermore, the microprocessor 17 clears the previous setting record after each nebulization session to ensure orderly continuous use.

[0020] Furthermore, to help users understand the remaining time, a digital tube is also provided on the outer casing 10. This digital tube is connected to the microprocessor 17 and is used to display the set time and the remaining time.

[0021] Furthermore, the microprocessor 17 has PA7 pin, PA5 pin and PB3 pin, the digital tube has a tens digit selection pin, which is connected to the PA7 pin of the microprocessor 17 by a wire, the units digit selection pin is connected to the PA5 pin of the microprocessor 17, and the segment selection pins are connected to the PB0-PB7 pins of the microprocessor 17 respectively, so that the digital tube can display the set time and the remaining time, and the control button 16 is electrically connected to the PB3 pin of the microprocessor 17.

[0022] Furthermore, an air inlet 18 is provided at the position corresponding to the compressed air pump 11 on the outer casing 10, so that external airflow can enter when the compressed air pump 11 is working, ensuring that the compressed air pump 11 can work normally and output high-pressure airflow.

[0023] It should be noted that a power interface is also provided at the bottom of the housing 10. This power interface is used to connect to an external power source to provide operating power. The power interface is preferably connected to a 5V2A charging head for power supply.

[0024] In summary, this application achieves timing within any time period through the timing control circuit 15, adapting to diverse clinical medication needs. Furthermore, the power supply filtering and current limiting design of the timing control circuit 15 ensures stable power supply, avoiding timing errors or air pump start-stop failures caused by voltage fluctuations. It also features a simple structure, low cost, and can meet different usage requirements. Moreover, it can be continuously set for continuous nebulization, making it more versatile.

[0025] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
