Abstract
Description
Technical Field
[0001] This application relates to the field of fan technology, and in particular to a spray fan. Background Technology
[0002] In summer, the weather is hot, and fans are inconvenient to carry when people go out. Ordinary handheld fans are not very effective at cooling people, and crowded places are filled with unpleasant odors such as sweat, causing discomfort. Therefore, various types of mist fans have been developed, which can simultaneously blow air and humidify the air, helping to cool the air and replenish its moisture content. However, the design of the mist fan's water tank is a significant technical challenge in the industry, affecting the fan's weight, size, and / or the duration of the water spray. Utility Model Content
[0003] The main purpose of this application is to provide a spray fan designed to improve the spraying and blowing effects.
[0004] To achieve the above objectives, this application provides a spray fan, including a housing, a fan assembly, and an atomizing element. The housing includes an annular enclosure structure, a mounting portion located on the annular inner side of the enclosure structure, a connecting portion connecting the enclosure structure and the mounting portion, and an extension portion connecting the lower part of the enclosure structure. The enclosure structure has a water inlet hole and a first cavity communicating with the water inlet hole. The extension portion has a second cavity communicating with the first cavity and a water outlet hole communicating with the second cavity. The fan assembly is mounted on the mounting portion. The atomizing element is disposed corresponding to the water outlet hole and is used to atomize the liquid in the water outlet hole into a spray and spray it out.
[0005] In the spray fan provided in this application embodiment, the enclosure structure not only has an installation part for mounting the fan assembly on its inner side, thereby forming an air duct around the fan assembly to reduce air leakage and improve air efficiency, but the enclosure structure also has a first cavity and a water injection hole, thus serving as a water tank for containing liquid. That is, it integrates at least two functions: air duct enclosure and liquid containment. Compared with other spray fans that have at least two components, air duct and water tank, the spray fan in this application embodiment has a higher degree of component integration, is simpler to assemble, and has a smaller size and weight, which is in line with the development trend of spray fans.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] First Embodiment
[0021] Please see Figures 1 to 10The first embodiment of this application provides a spray fan 1000 including a housing 10, a fan assembly 20, and an atomizing element 30. The housing 10 includes an annular enclosure structure 11, a mounting portion 12 located on the annular inner side of the enclosure structure 11, a connecting portion 13 connecting the enclosure structure 11 and the mounting portion 12, and an extension portion 14 connecting below the enclosure structure 11. The enclosure structure 11 has a water inlet 111 and a first cavity 112 communicating with the water inlet 111. The extension portion 14 has a second cavity 141 communicating with the first cavity 112 and a water outlet 142 communicating with the second cavity 141. The fan assembly 20 is mounted on the mounting portion 12. The atomizing element 30 is disposed corresponding to the water outlet 142 and is used to atomize the liquid in the water outlet 142 into a spray and spray it out.
[0022] In the spray fan 1000 provided in this application embodiment, the enclosure structure 11 not only has an mounting part 12 for mounting the fan assembly 20 on its inner side, thereby forming an air duct around the fan assembly 20 to reduce air leakage and improve air efficiency, but the enclosure structure 11 also has a first cavity 112 and a water injection hole 111, so it can be used as a water tank to contain liquid. That is, it integrates at least two functions: air duct enclosure and liquid containment. Compared with other spray fans 1000 that have at least two components, air duct and water tank, the spray fan 1000 of this application embodiment has higher component integration, simpler assembly, smaller size and weight, which is in line with the development trend of spray fans 1000.
[0023] Furthermore, since the atomizing element 30 is provided corresponding to the water outlet 142 of the extension 14, the entire enclosure structure 11 can be configured as a double-layer structure as a water tank, which is larger in size and capacity than the water tank of the existing spray fan 1000 (such as the arc-shaped area above the fan head), and can increase the spraying time.
[0024] Furthermore, the enclosure structure 11 includes a first enclosure portion 11a and a second enclosure portion 11b, which are joined together to form the first cavity 112. The extension portion 14 includes a first portion 14a and a second portion 14b, which form the second cavity 141. The first enclosure portion 11a connects to the connecting portion 13. The first enclosure portion 11a, the connecting portion 13, the first portion 14a, and the mounting portion 12 are integrally formed structures, as are the second enclosure portion 11b and the second portion 14b. The integral formation of the first enclosure portion 11a, the connecting portion 13, the first portion 14a, and the mounting portion 12, and the integral formation of the second enclosure portion 11b and the second portion 14b, results in a high degree of component integration in the enclosure structure 11, lower assembly costs, and higher structural strength compared to assembled structures.
