Description

Technical Field

[0001] This utility model relates to a controller with a power-on frequency sweep function. When the atomizer is powered on each time, the controller can lock the optimal oscillation frequency of atomization by sweeping the frequency. Background Technology

[0002] Medical nebulizers are mainly used to treat various diseases of the upper and lower respiratory systems, such as colds, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis, and other diseases occurring in the trachea, bronchi, alveoli, and pleural cavity.

[0003] Nebulized inhalation therapy is an important and effective treatment method for respiratory diseases. It uses a nebulizer to atomize the medication into tiny particles (such as aerosols), which are then inhaled and deposited in the respiratory tract and lungs, thus achieving painless, rapid and effective treatment.

[0004] like Figure 1 As shown, utility model patent application number 201390000437.4 discloses an atomizer 1, including a controller 2, whose output end is connected to a vibrating mesh atomizer head 3 and whose input end is connected to a USB cable and a plug 4 for connecting to a host system. The connection between the plug 4 and the controller 2 is a USB cable 5 having power and data channels. The controller 2 is connected to the atomizer head 3 via the cable and the plug.

[0005] The controller 2 includes a boost circuit 10, a processor 11, and a drive circuit 12. The boost circuit 10 receives a 12V DC voltage from a range of 4.75V-5.25V DC to generate the drive circuit 12, producing a drive frequency of 120 to 150kHz to drive the nebulizer 3 to generate sufficient amplitude to atomize the liquid medicine into an aerosol. However, each time the nebulizer is turned on and the plug 4 initially supplies power, the controller 2 does not perform a frequency sweep to obtain the optimal drive frequency required by the nebulizer oscillator at that moment. An inappropriate drive frequency may cause the nebulizer oscillator to over-oscillate, resulting in a temperature rise. Once the temperature rises above 10°C, it will significantly affect the quality of the liquid medicine. Utility Model Content

[0006] Purpose of the utility model: In view of the fact that an inappropriate drive frequency of the controller may cause excessive oscillation of the nebulizer oscillator and thus affect the quality of the liquid medicine, this utility model discloses a controller with a power-on frequency sweep function. This utility model can scan multiple oscillation frequencies and lock the optimal frequency for the nebulizer to perform atomization every time the nebulizer is turned on and powered by the USB plug, so as to ensure that the above problems can be effectively solved.

[0007] Technical solution: A controller with a power-on frequency sweep function supplies power to the controller and atomizer head via a USB plug. The controller consists of a current detector, a processor, and a drive circuit. The processor sets multiple oscillation frequencies and supplies them to the drive circuit sequentially. The current detector measures the current consumed by each oscillation frequency and feeds it back to the processor for recording. The processor scans the records and locks the oscillation frequency corresponding to the largest current value, setting the oscillation frequency as the optimal oscillation frequency for atomization when the atomizer is powered on and initially supplied by the USB plug.

[0026] To help those skilled in the art understand the technical features, content, advantages, and effects of this utility model, the following detailed description will be provided in conjunction with the accompanying drawings and in the form of embodiments. The accompanying drawings are for illustrative purposes only and are not necessarily the actual proportions and precise configurations of this utility model after implementation. Therefore, the proportions and configurations of the accompanying drawings should not be used to interpret or limit the scope of this utility model in actual implementation.

[0027] Please see Figure 2 The controller 2a, which has a power-on frequency sweep function, receives power from the USB plug 4a to the controller 2a and the atomizer head 3a when powered on.

[0028] The controller 2a consists of a current detector 10a, a processor 11a, and a drive circuit 12a. The processor 11a sets multiple oscillation frequencies and provides them to the drive circuit 12a sequentially. The current detector 10a measures the current value consumed by each oscillation frequency and feeds it back to the processor 11a for recording. The controller scans the records and locks the oscillation frequency corresponding to the largest current value. This oscillation frequency is set as the optimal oscillation frequency for atomization when the atomizer 1a is turned on and powered by the USB plug 4.

[0029] In summary, the core value of this utility model lies in providing a controller for an atomizer with a power-on frequency sweep function. Each time the device is powered on, the controller can sweep the frequency to lock the optimal oscillation frequency for the atomizer to perform atomization, thereby avoiding the temperature rise caused by excessive oscillation of the atomizer due to inappropriate drive frequency.
