Description

Technical Field

[0001] This utility model belongs to the technical field of bladeless fans for both heating and cooling, and specifically relates to a multi-layer waterproof structure for a humidification module of a bladeless fan for both heating and cooling. Background Technology

[0002] Most fans on the market currently only have the single function of blowing out cool air, and are mostly only used in hot summer weather, limiting their use to a limited seasonal period. Therefore, traditional fans have low usage rates and poor applicability. To address this, bladeless fans with both cooling and heating functions have emerged, while also incorporating humidification to ensure that the air is not too dry while providing warmth.

[0003] Existing humidification modules are assembled from multiple structures, and the sealing at the assembly joints is limited, which may lead to leakage at the seams of the splicing assembly, causing other electronic components inside the humidification module to be damaged by moisture. To address this, this utility model designs a multi-layer waterproof structure for a bladeless fan humidification module that provides both heating and cooling. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer waterproof structure for a bladeless fan humidification module that provides both heating and cooling, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer waterproof structure for a bladeless fan humidification module, comprising a water collection recess on the bottom shell of the main housing, a water storage tank integrally formed with the main housing, a water guide channel on the top edge of the water storage tank, and the water guide channel extending downwards to the top surface of the water collection recess, the water collection recess having multiple drain outlets, a humidification base installed on the top edge of the water storage tank, the bottom of the humidification base extending into the water storage tank to form an extension conduit, and a [missing information - likely a device or component] installed at the bottom end of the extension conduit. The humidifier base has an atomizing plate and a humidifying sealing cover fixedly installed on its top. The top edge of the humidifier base and the bottom edge of the humidifying sealing cover are sealed by a raised sealing structure. The inner side of the humidifier base is provided with a pressure sealing element for secondary sealing of the gap between the humidifying sealing cover and the humidifier base. The other end of the humidifier base is provided with a drain hole that is aligned with the water guide groove. The drain hole communicates only with the gap between the humidifier base and the humidifying sealing cover, and the bottom edge of the drain hole is sealed to the top edge of the water guide groove by an interference fit seal.

[0006] Preferably, a top cover is sealed on the top of the main housing, and the top cover is provided with a spray nozzle aligned with the extension conduit.

[0007] Preferably, the raised sealing structure includes an integrally formed sealing raised edge on the top edge of the humidifying base, and an upper sealing groove opened on the bottom edge of the humidifying sealing cover and aligned with the sealing raised edge, wherein the sealing raised edge extends into the upper sealing groove for a tight seal.

[0008] Preferably, the press-fit sealing element includes an atomizing sealing ring disposed on the inner side of the humidifying base, and an extension rib extending downward from the inner edge of the humidifying sealing cover, the extension rib being press-fitted onto the atomizing sealing ring for sealing.

[0009] Preferably, the interference seal includes a raised ring disposed at the top edge of the water guide groove, a sealing ring groove disposed at the bottom edge of the drain hole, and an O-ring rubber ring interference disposed in the sealing ring groove, wherein the raised ring extends into the sealing ring groove and abuts against the O-ring rubber ring.

[0010] Preferably, the water guide channel and the main housing are integrally formed, and the humidifying base and the outer side of the humidifying sealing cover are assembled by screws.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By designing multiple waterproof structures, the water mist generated by the atomizing plate can be smoothly sprayed out of the spray nozzle, improving the sealing performance. The equipped drainage structure ensures that water can be smoothly discharged during user use or in the event of failure of some sealing mechanisms, minimizing the risk of water leakage and short circuits, thereby improving product safety, ensuring product performance and lifespan reliability, and enhancing the user experience.
