[0001] This utility model belongs to the technical field of air purification equipment, and in particular relates to an air purification device and control circuit. Background Technology
[0002] Currently, most negative ion generators and ozone generators on the market are independent devices, and each device needs to be equipped with its own power supply and control circuit, which results in high costs, large space occupation, and complex structure; and they cannot achieve coordinated control and flexible switching of functions. Summary of the Invention

[0006] The power supply component is equipped with a unified power input interface and power management circuit. The power management circuit and the main control board distribute power to the negative ion generating module and the ozone generating module.
[0007] A control circuit, connected to the main control board, is used to adjust and control the working state of the negative ion generating module and the ozone generating module. The control circuit includes a mode selection unit, a timing control unit, and a safety protection unit. The control circuit is configured to achieve at least one of the following: an independent working mode for negative ions, an independent working mode for ozone, and a collaborative working mode. In the collaborative working mode, the negative ion generating module and the ozone generating module work alternately according to a preset timing sequence.
[0008] Furthermore, the power management circuit has a built-in power distribution module, which provides time-sharing power to the negative ion generating module and the ozone generating module according to the instructions of the control circuit.
[0009] Furthermore, the mode selection unit is used to switch between the negative ion independent working mode, the ozone independent working mode, the collaborative working mode, and the timer mode; the timer mode allows setting the working time of the device and automatically shutting it down after the set time is reached.
[0010] An air purification device control circuit is provided. The core controller of the control circuit is a microcontroller. The control circuit controls the working timing of the negative ion generating module and the ozone generating module through PWM signals to avoid synchronous operation interference.
[0011] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects:
[0012] In this utility model, the two modules are physically integrated through an integrated shell, saving more than 50% of the installation space. It can simultaneously support three working modes: negative ion, ozone, and ozone and negative ion synergy, meeting the needs of different purification scenarios. It shares a power supply and control circuit, reducing material costs by 30% compared to independent devices. It adopts a time-sharing multiplexing control algorithm to avoid electrical interference when the two modules work simultaneously. Unified power management and control logic reduce the equipment failure rate. Its size is smaller than that of independent devices, making it suitable for various scenarios such as vehicle and home use. Attached Figure Description
