Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.
The first embodiment is as follows:
as shown in fig. 1, the present embodiment provides a bladeless fan with a lifting outlet, including a housing 1 and a driving component 2 installed inside the housing 1, where the driving component 2 has a specific structure: the driving assembly 2 comprises an air outlet pipe 3, a motor 4, a wind wheel 5 and a shell 6. The housing 6 is fixed in the housing 1, wherein the wind wheel 5 is fixed to the rotation shaft of the motor 4, and the wind wheel 5 and the motor 4 are mounted in the housing 6. The shell 6 is provided with an air inlet and an air outlet, the air inlet is communicated to the outside of the shell 6, and the air outlet pipe 3 is arranged at the air outlet and used for discharging airflow generated by the wind wheel 5 in the shell 6 from the air outlet pipe 3.
The equipment also comprises an annular air outlet head 7, and the specific shape of the air outlet head 7 is not limited in the embodiment and can be circular, square, oval, polygonal and the like. Casing 1 is equipped with upper end open-ended installation cavity 8, go out wind head 7 along vertical direction sliding connection in installation cavity 8. The specific sliding connection structure is as follows: the internal surface of the vertical lateral wall of installation cavity 8 is equipped with the slide, the surface of going out wind head 7 be equipped with the slider that the slide corresponds slides and then makes wind head 7 and installation cavity 8 sliding connection in the slide that corresponds through the slider. The slide way and the slide block can be provided with two pairs which are respectively positioned at two sides of the air outlet head 7. The air outlet head 7 adopts a sliding connection structure of a sliding block and a sliding way, and can also adopt common sliding connection structures such as a guide rail and the like, thereby being beneficial to reducing the production and manufacturing difficulty.
In addition, go out the wind head 7 with go out tuber pipe 3 turn on-off connection, through stretching out casing 1 with the wind head 7 and then discharge the air current that drive assembly 2 produced from the wind head 7. Specifically, be equipped with the air inlet opening on the lateral wall that air-out head 7 and air-out pipe 3 are relative, after air-out head 7 rose to the highest position, the air inlet opening just right with air-out pipe 3 to switch on the wind channel. When the air outlet head 7 descends to the lowest position, the air inlet opening is staggered with the air outlet pipe 3, so that the air channel is closed.
In the embodiment, the function of the extended air outlet head 7 is the same as that of the existing bladeless fan, and the occupied space is also the same.
