Description

Technical Field

[0001] This utility model relates to the field of air circulation fan technology, and in particular to a desktop air circulation fan. Background Technology

[0002] Desktop air circulators are convenient fans designed for personal use or small spaces. Combining the advantages of air circulation and quiet operation, they are ideal companions for offices, bedrooms, or study desks. These fans typically feature a compact and elegant design, saving space while efficiently circulating indoor air to create smooth airflow and effectively improve cooling, bringing a touch of coolness even on hot summer days. Their unique spiral airflow design and adjustable speed settings not only quickly and evenly distribute cool air but also allow for precise adjustments to suit individual needs, making them a compact and practical home appliance that enhances the quality of life and work environments.

[0003] However, traditional air circulators lack a misting humidification function, leading to multiple inconveniences and shortcomings. In hot summers or dry environments, relying solely on air circulators for cooling is often ineffective, leaving users feeling stuffy and lacking coolness. Furthermore, the absence of humidification prevents effective increases in indoor humidity, potentially exacerbating dry skin and affecting respiratory health, causing symptoms like sore throat and dry cough. Moreover, for users seeking a high-quality lifestyle, the limited functionality of traditional air circulators restricts their versatility and flexibility. For instance, in situations requiring simultaneous cooling and humidification, users may need to use multiple devices, increasing energy consumption, occupying more space, and affecting indoor cleanliness and aesthetics.

[0004] Furthermore, we disclose a desktop air circulator fan to meet the practical needs of existing air circulator fans, which have poor cooling effects and cannot humidify indoor environments. Utility Model Content

[0013] The beneficial effects of this utility model are:

[0014] 1. This desktop air circulator fan integrates a misting humidification function through its misting component. It not only inherits the advantages of traditional air circulator fans—efficiently agitating indoor air, creating smooth circulation, and rapidly improving cooling—but also, in hot summers or dry environments, utilizes multiple atomizing nozzles inside the casing in conjunction with the misting component to achieve precise humidification of the indoor environment. This effectively increases air humidity, providing users with a cooler and more comfortable experience, while alleviating problems such as dry skin and throat discomfort caused by dry air. Furthermore, it meets users' dual needs for cooling and humidification in various scenarios, eliminating the need for additional humidification equipment. This saves energy and maintains indoor cleanliness and aesthetics, significantly improving users' living and working environments.

[0015] 2. This desktop air circulator fan, through its adjustable components, offers greater flexibility and versatility in functionality, meeting diverse user needs for different spray angles. The combination of components such as the rotating ring, insert rod, fixing plate, telescopic spring, and slider allows users to easily and precisely adjust the spray angle of the atomizing nozzle. This design not only enhances the product's practicality and operability but also provides a more personalized user experience. The wedge, sliding rod, and roller design further enhance the flexibility and accuracy of adjustment, allowing the atomizing nozzle to rotate within the housing to achieve spray effects across different ranges.
