On March 9, 2018, a significant event took place in the Kerry Hotel in Pudong, Shanghai. The China Household Electrical Appliances Association, along with the full drinking media of the drinking water era and the AWE China Environmental and Health Appliances Summit Forum, co-hosted a forum. This event was also supported by Chinese net media. Attendees included Xu Dongsheng, Vice Chairman of the China Household Electrical Appliances Association; Bai Xuetao, Research Fellow at the Environmental Monitoring Center of the Chinese Center for Disease Control and Prevention; Yue Renliang, Associate Research Fellow at the Institute of Process Research, Chinese Academy of Sciences; Chen Qi, General Manager of AO Smith Water Purification Division; and Ji Bing, General Manager of Air Purification Products Division. Representatives from major e-commerce platforms such as JD.com, Suning, and Tmall were also present.

**Safety, environmental protection, and high efficiency have become the future development trend of two net products**
At the forum, Xu Dongsheng, Bai Xuetao, and Yue Renliang emphasized that as environmental challenges continue to grow, consumer demand for water and air purification products will only increase. They noted that future developments will focus on safety, reliability, energy efficiency, and environmental friendliness. In terms of water purification, reverse osmosis remains the most effective technology. For air purification, while outdoor environments improve, addressing indoor pollutants like formaldehyde is key to future advancements.

**The three major e-commerce companies gathered together, e-commerce big data to support the "new retail" era, two net consumption upgrades**
In 2017, often referred to as the “Year of New Retail,†the lines between online and offline shopping began to blur. Ye Bo of JD.com, Su Xiaoyong of Suning, and Nanxuan of Tmall shared insights based on e-commerce data showing a surge in demand for high-end water and air purification products. Consumers are increasingly seeking premium options priced above 3,000 yuan. E-commerce platforms are now focusing on omnichannel strategies to break down barriers between online and offline shopping, enhancing convenience for users.

**AO Smith water purification variety of innovative boutique solutions to consumer pain points define a new way of life**
As a leader in the industry, AO Smith has consistently focused on solving real user problems through innovation. Since entering the Chinese market, the company has developed over 100 patented technologies. One notable product is the MAX3.0 Plus long-life reverse osmosis purifier, which significantly improves filter lifespan while maintaining high purification efficiency. In 2018, AO Smith introduced a hot water purifier that allows instant access to hot water, eliminating the need to wait for boiling. It also launched a compact integrated design, making installation more flexible and space-efficient.

High Frequency Power Supply
I. Definition and overview
A high-frequency UPS is an Uninterruptible Power Supply (UPS) technology. It uses the high-frequency switching power supply technology to convert the input AC power into high-frequency AC power through the inverter and then converts the input AC power into stable direct current (DC) power for electronic devices. High frequency UPS plays an important role in modern power supply system because of its efficient conversion rate, small size design and fast response ability.
Two, the main characteristics
Efficient conversion rate:
High frequency UPS adopts a new IGBT (insulated gate bipolar transistor) inverter technology, and its conversion efficiency can reach more than 90%, which is much higher than the traditional low-frequency UPS, effectively reducing energy loss and improving the use efficiency.

Small volume design:
Because high-frequency UPS uses a more compact design, its volume is significantly smaller than low-frequency UPS, and its footprint is smaller, which is very suitable for use in space-limited environments, such as data centers and computer rooms. (source ibid.)
High power density:
The power density of high-frequency UPS is large, and it can provide greater power output in a small volume, improving the capacity and power supply efficiency of the equipment.
Quick response:
The high frequency UPS has a fast response capability and can provide stable power for the device immediately when the power supply of the grid is interrupted, ensuring that the continuous operation of the device is not affected.
Intelligent management:
Many high-frequency UPS are equipped with advanced intelligent management systems, which can monitor the status of power supply, battery status, load situation in real time, and have fault diagnosis, automatic switching, remote monitoring and other functions, improving the reliability and maintainability of the system.
