Description

Technical Field

[0001] This utility model relates to the field of fan accessory technology, and in particular to the atomizing duct adapter structure of an air convection circulation fan. Background Technology

[0002] Air convection circulators are equipped with atomizing components that spray mist while expelling air. The mist is generated by the atomizing components and delivered through a flexible conduit to the spray nozzle in the center of the fan blade cover. The atomizing components are typically located inside the support column. This causes the flexible conduit to extend upwards along the support column, then around the perimeter of the fan blade cover, finally connecting to the spray nozzle in the center. The fan blade assembly can at least move up and down to provide multi-directional airflow. When the fan blade assembly moves up and down, the flexible conduit moves with it. This can easily cause folds in the flexible conduit at the points of movement, affecting the flow of mist and creating resistance that hinders the up-and-down movement of the fan blade assembly, resulting in somewhat uneven movement.

Detailed Implementation

[0012] The present invention will now be described in further detail with reference to the accompanying drawings.

[0013] refer to Figures 1 to 7 The atomizing duct adapter structure of the air convection circulation fan; refer to Figures 4 to 7 The air convection circulation fan includes an air outlet assembly 1, a support assembly 2, and an atomizing assembly 3; The air outlet assembly 1 includes a first motor and a fan blade. The first motor drives the fan blade to rotate. The air outlet assembly 1 is located on the top of the support assembly 2, for example, it is rotatably connected. The air outlet assembly 1 achieves rotation in the up and down directions through an oscillating mechanism. The oscillating mechanism consists of a small motor and a gear set, etc.

[0014] The support assembly 2 is used to support the air outlet assembly 1. The support assembly 2 is a shell structure, and an atomizing assembly 3 may be installed inside it. The atomizing assembly 3 includes a water tank 31 and an atomizing generator 32. The atomizing generator 32 may be an ultrasonic atomizer, a compressor atomizer, or a mesh atomizer, etc., used to generate mist. The mist is delivered to the spray nozzle 11 through a duct. The spray nozzle 11 may be located in the middle of the fan blade mesh cover of the air outlet assembly 1. The atomizing assembly 3 may also be equipped with a small fan to drive the mist flow towards the spray nozzle 11. Thus, the air convection circulation fan can not only generate airflow, but also generate mist to achieve humidification and improve the cooling effect; the aforementioned air outlet component 1, atomizing component 3 and oscillation mechanism are all existing technologies, and are only applied here.

[0015] refer to Figures 1 to 4 The adapter 5 includes a base 51, an end cap 52, and a movable tube 53; The base 51 can be fixed to the top of the support mechanism of the circulating fan; The base 51 includes a first channel 511 and a second channel 512 that are interconnected. The first channel 511 is used to connect to the atomizing component 3. The first section 53a of the movable tube 53 is rotatably connected to the second channel 512, and the second section 53b of the movable tube 53 is used to connect to the spray nozzle 11 of the air outlet assembly 1 of the circulating fan. The first pipe section 53a and the second pipe section 53b are connected at a 90-degree angle; that is, the movable pipe body 53 is a two-way pipe with an approximately 90-degree structure.

[0016] The first pipe section 53a is provided with a shoulder 531, and the end face of the second channel 512 is provided with a shaft groove 513 that mates with the shoulder 531; the shoulder 531 and the shaft groove 513 mate to improve the connection accuracy and the smoothness of rotation, and also to achieve a degree of freedom limitation in the axial direction. The end cap 52 is used to limit the axial position of the first pipe segment 53a, that is, the end cap 52 limits another degree of freedom of the first pipe segment 53a.

[0017] Thus, the first section 53a of the movable tube 53 extends horizontally along the radial direction of the air outlet assembly 1, and the second section 53b extends horizontally along the axial direction of the air outlet assembly 1. The adapter 5 is located at the connection between the support assembly 2 and the air outlet assembly 1. In this way, when the air outlet assembly 1 is rocked up and down, the movable tube 53 can rotate up and down with the air outlet assembly 1, thereby reducing the resistance to the air outlet assembly 1 when it is rocked up and down, and ensuring that the mist can flow smoothly.

[0018] refer to Figure 3 The first pipe section 53a has a first annular groove 532 at its end, and a sealing ring 533 is provided in the first annular groove 532. The sealing ring 533 can abut against the inner wall of the second channel 512, playing a certain degree of sealing role and preventing or reducing the leakage of mist. The sealing ring 533 can be made of silicone.

[0019] The axes of the first channel 511 and the second channel 512 are perpendicular to each other, forming a 90-degree structure. The first channel 511 extends downward for easy connection with the atomizing component 3, while the second channel 512 extends horizontally for easy connection with the first section 53a of the movable tube 53, so that the first section 53a extends horizontally along the radial direction of the air outlet component 1.

[0020] refer to Figure 2 and Figure 3 The end cap 52 is provided with an opening 521 and a baffle 522. The end cap 52 is fitted onto the movable tube 53 through the opening 521. The baffle 522 is provided on the side of the shoulder 531 away from the shaft groove 513, thereby achieving axial positioning of the first tube section 53a.

[0021] refer to Figure 2 The base 51 is provided with a first assembly hole 514, and the end cap 52 is provided with a corresponding second assembly hole 523. Thus, by passing screws or the like through the second assembly hole 523 and the first assembly hole 514 in sequence, they are screwed into the screw hole of the support component 2, thereby realizing the connection between the end cap 52 and the base 51, and at the same time, fixing the base 51 to the support component 2.

[0022] refer to Figure 4 The first channel 511 is connected to the atomizing component 3 via the first flexible conduit 41, and the second pipe section 53b is connected to the spray nozzle 11 via the second flexible conduit 42. Both the first flexible conduit 41 and the second flexible conduit 42 can be corrugated plastic pipes, and the connection of the flexible conduits can be fixed by clamps or the like. The first flexible conduit 41 can be located inside the support component 2; the second flexible conduit 42 extends around the periphery of the fan blade screen and then connects to the spray nozzle 11.

[0023] The above description only discloses some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
