Description

Magnetic fan unit

technical field

The invention relates to a fan group, in particular to a fan group spliced through magnetic suction.

Background technique

According to the investigation, the current fan manufacturers design on the fan frame in order to meet the needs of users to splice multiple fans horizontally. For example, China Taiwan TW M396884 and the United States US2017/0331346 disclose the technical means of splicing fans through additional fixing parts. Specifically, the fan frames are provided with coupling grooves or coupling parts, and the coupling grooves and The connecting parts are respectively provided with through holes in which the fixing parts are set. When the user splices the fans, the connecting part on one of the fans is inserted into the combining groove on the other fan, so that the connecting part The perforations on the upper part are aligned with the perforations on the combining groove, and then the fixing part is used to pass through the through holes, so that the fixing part restricts the combining part and the combining groove. However, the splicing method of the above-mentioned multiple fans relies heavily on the limiting function provided by the fixing piece. Once the user fails to use the fixing piece when splicing the fans, the fans cannot be fixed and are prone to displacement. In addition, conventionally, the fixing part is an independent part, and generally speaking, the size of the fixing part is obviously smaller than that of the fans, so the fixing part is easily lost during storage, causing inconvenience to users.

In order to improve the above-mentioned problems, fan manufacturers have spliced these fans together without additional fixing parts, as disclosed in patents such as US 10,690,336B and Chinese CN 101725571B. Take the United States US10,690,336B as an example, these fans are provided with slots or positioning blocks on the fan frame, when the user splices these fans, the positioning block of one of the fans is assembled to the other fan These fans form an assembly relationship in the card slot. However, the conventional technical solution of directly forming the mechanical connection structures on the fans is prone to misalignment of the mechanical connection structures due to excessive dimensional tolerances among the fans. Furthermore, the conventional fan has certain gestures when it is assembled or disassembled, which makes disassembly and assembly of the conventional fan complicated and inconvenient for users.
