First of all, from the appearance of the product, the overall image of this air purifier is extended with the image of a housekeeper as the background, matching its functional structure and highlighting its appearance personality. In terms of product expertise, I have conducted research on various purifiers in the market. Now the air purifiers on the market mainly have several technical cores: negative ion technology, photocatalyst technology, HEPE technology (also known as the abbreviation of efficient purification), and we use negative ion purification technology because it can produce negative ions to purify dust, odor, and bacteria in the air, another reason is that negative ion technology does not need a filter screen or a fan of a traditional air purifier, which can achieve extreme noise reduction and does not require excess material loss and cleaning. Then see the function positioning of this product. The first remote control can set the mode, parameters, time, route, and the second autonomous operation through the mobile phone APP. It can independently carry out route planning and corresponding route planning at the set time node. The purification work of the mode, the third humanized interactive experience, first set different situations on the interactive interface of the product, and will give relatively professional recommendations according to changes in the environment, secondly, two innovative functions have been added to the product itself: screen casting and shooting. The product is equipped with a hidden camera, which can record life video and upload it to the mobile APP at ordinary times, and can also monitor the family environment in real time, which is echoed and related to the appearance of the housekeeper. The screen casting function can share spare time with family members. APP will cooperate with major audio-visual platforms to form a network library to serve customers, later, corresponding managers will also carry out regular upgrade and update services to continuously optimize the service system.
