The desktop Air Purifier mainly focuses on the purification of personal private space in the open office area, and the air purification goal is one-to-one. Different from the traditional whole-house air purification, this machine uses a front wide-angle air outlet to cover the breathing area of the face. The air outlet angle that can be adjusted up and down allows the purified air to be sent directly to the user.

Taking into account the common pollution in the office environment, the Mijia desktop air purifier uses a high-precision filter, which is officially claimed to be able to filter out 99.6% of particles with a particle size of more than 0.3μm, and to deal with PM2.5, pollen allergens, Dust, second-hand smoke and other pollutants.
The latest intelligent electric valve controller
Shenzhen Dongyi Electronics Co., Ltd., established in 1993, is a leading high-tech enterprise specializing in the design, development, manufacturing, and marketing of industrial automation products. As one of the pioneers in China's industrial automation measurement and control instrumentation sector, the company has consistently focused on innovation and quality. With a strong technical team, advanced production and testing equipment, and a commitment to excellence, Dongyi has earned numerous national patents in instrumentation technology, including patent numbers ZL94212013.2, ZL95228872.9, and ZL00133062.4.
The company actively implements the ISO9001 quality management system, ensuring that all products meet the highest industry standards. Over the years, Dongyi has continuously upgraded its product line, particularly the ZXQ series of high-performance digital instruments. These devices are widely used across various industries, such as power generation, steel, petrochemicals, and light manufacturing. They serve as intelligent regulators, DCS, PLC systems, and inverter backup units, offering seamless integration with different control systems.
The ZXQ series supports direct operation of actuators and inverters, enabling smooth transitions between manual and automatic modes without disturbance. This feature greatly simplifies system start-up and fault handling processes. The positioner can receive DC 4-20mA signals from upper instruments or three-wire signals (or valve position feedback) from lower actuators, allowing precise control of valve opening and regulation.
Key features of the ZXQ series include:
1. Control accuracy: 0.1% to 3.0% (adjustable)
2. Compatibility with electric actuator feedback signals: Potentiometer range of 500Ω to 10KΩ
3. Support for external control signals (DC): 4-20mA
4. Adjustable settings for "forward/reverse actuator" and "interrupt" mode (OPEN, STOP, SHUT)
5. Option to enable or disable the electronic system
6. SCR output: AC 600V, 25A
7. Output actuator position signal: Low drift 4-20mADC, fully isolated from input via optical isolation
8. Operating temperature: 0–70°C (user-adjustable), humidity ≤90% RH
9. Over-temperature protection
10. Dimensions available in online descriptions
11. On-screen calibration of input signals corresponding to the actuator
12. Interference-free manual/auto switching
13. Actuator stall detection and control
14. Adjustable accuracy and re-adjustment time settings
15. Password protection to prevent unauthorized use
16. Intelligent step adjustment based on angular positions for precise actuator positioning
17. Error code display for quick troubleshooting
18. RS485 communication capability for extended functionality
19. Customization options for special requirements
Dongyi Electronics continues to deliver reliable, high-performance solutions tailored to the evolving needs of modern industrial automation. Its dedication to quality, innovation, and customer satisfaction has made it a trusted name in the field. Whether for standard applications or custom designs, the company remains committed to providing cutting-edge technology that meets global standards.
