Description

Technical Field

[0001] This invention relates to the field of bladeless fan technology, and more specifically to a bladeless fan with a liftable air outlet. Background Technology

[0002] The principle of bladeless electric fans is based on the technology of jet engines and automobile turbochargers. Air is drawn in through the air intake at the bottom, and an impeller hidden inside the casing blows the air out, ultimately forming a continuous flow of cold air.

[0003] There are various shapes and air outlet methods for bladeless fans, such as bladeless fans with ring-shaped air outlets, water-cooled bladeless fans with ring-shaped air outlets, and bladeless fans with vertical strip-shaped air outlets (also known as tower fans). Regardless of the type of bladeless fan, its power components (i.e., motor and impeller) are located in the lower part of the casing, while the upper part of the casing is the air outlet structure.

[0004] While the aforementioned bladeless fans possess numerous advantages, they still have areas for improvement. For instance, the exhaust structure is part of the casing and cannot be extended or retracted, thus occupying a significant amount of space. This results in substantial packaging material requirements for mass production. Furthermore, the large transport space they occupy during transit prevents cost reduction. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a bladeless fan with a liftable air outlet, which reduces the consumption of packaging materials, lowers packaging costs, and simultaneously reduces the space occupied in transportation, thereby reducing transportation costs.

[0006] The present invention provides a bladeless fan with a lifting air outlet, comprising a housing and a drive assembly installed inside the housing; the drive assembly is provided with an air outlet pipe;

[0007] It also includes ring-shaped air outlets;

[0008] The housing has a mounting cavity with an opening at the top, and the air outlet is slidably connected to the mounting cavity along the vertical direction;

[0009] The air outlet is connected to the air outlet pipe, and the airflow generated by the drive component is discharged from the air outlet by extending the air outlet out of the housing.

[0010] The beneficial effects of this invention are reflected in:

[0011] When the air outlet is extended, it functions the same as existing bladeless fans and occupies the same space. However, when the air outlet is retracted into the housing, it reduces the space occupied by the air outlet compared to existing bladeless fans. Consequently, the volume of packaging boxes and bags will be reduced, especially for mass production, reducing packaging material consumption and helping to lower packaging costs. For transportation, the reduced transport volume allows for larger quantities to be transported at once, thereby lowering transportation costs.

[0012] Preferably, the inner surface of the vertical sidewall of the mounting cavity is provided with a slide rail, and the outer surface of the air outlet is provided with a slider corresponding to the slide rail. The air outlet is slidably connected to the mounting cavity by the slider sliding in the corresponding slide rail.

[0013] The air outlet adopts a sliding connection structure of slider and slide rail, or a common sliding connection structure such as guide rail, which helps to reduce the difficulty of production and manufacturing.

[0014] Preferably, it also includes a telescopic component; the air outlet is slidably connected to the mounting cavity via the telescopic component.

[0015] Preferably, the telescopic assembly includes a telescopic tube; both ends of the telescopic tube are connected between the air outlet and the bottom wall of the mounting cavity.

[0016] Preferably, there are two telescopic tubes, and the two telescopic tubes are located on both sides of the mounting cavity.

[0017] Preferably, the telescopic tube is provided and is located in the middle of the mounting cavity.

[0018] Preferably, the inner cavity of the telescopic tube is conductively connected between the air outlet and the air outlet pipe.

[0019] The air outlet and mounting cavity can also be connected by a sliding telescopic tube. The telescopic tube extends to allow the air outlet to extend, and retracts to retract it. The telescopic tube can be used singly or in pairs, depending on the actual specifications of the extended head. Furthermore, the telescopic tube is hollow, also acting as a conduit to guide airflow from the outlet duct to the air outlet. In short, the telescopic tube achieves a dual function: connecting the air outlet and guiding airflow. Attached Figure Description

[0029] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0030] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0031] Example 1:

[0032] like Figure 1 As shown, this embodiment provides a bladeless fan with a lifting air outlet, including a housing 1 and a drive assembly 2 installed inside the housing 1. The specific structure of the drive assembly 2 is as follows: the drive assembly 2 includes an air outlet duct 3, a motor 4, a fan wheel 5, and a housing 6. The housing 6 is fixed in the housing 1, wherein the fan wheel 5 is fixed to the rotating shaft of the motor 4, and the fan wheel 5 and the motor 4 are installed in the housing 6. The housing 6 has an air inlet and an air outlet. The air inlet is connected to the outside of the housing 6, and the air outlet duct 3 is installed at the air outlet to discharge the airflow generated by the fan wheel 5 in the housing 6.

[0033] This device also includes an annular air outlet 7. The specific shape of the air outlet 7 is not limited in this embodiment and can be circular, square, elliptical, polygonal, etc. The housing 1 has a mounting cavity 8 with an upper opening, and the air outlet 7 is slidably connected to the mounting cavity 8 along the vertical direction. Specifically, the sliding connection structure is as follows: the inner surface of the vertical sidewall of the mounting cavity 8 is provided with a slide rail, and the outer surface of the air outlet 7 is provided with a slider corresponding to the slide rail. The air outlet 7 is slidably connected to the mounting cavity 8 by the slider sliding in the corresponding slide rail. Two pairs of slide rails and sliders can be provided, located on both sides of the air outlet 7. The air outlet 7 adopts a sliding connection structure of slider and slide rail, or a common sliding connection structure such as a guide rail, which helps reduce manufacturing difficulty.

[0034] Furthermore, the air outlet 7 is electrically connected to the air outlet duct 3, allowing the airflow generated by the drive assembly 2 to be discharged from the air outlet 7 by extending it out of the housing 1. Specifically, the air outlet 7 has an air inlet on its side wall opposite to the air outlet duct 3. When the air outlet 7 rises to its highest position, the air inlet is directly opposite the air outlet duct 3, thus guiding the airflow. When the air outlet 7 descends to its lowest position, the air inlet is misaligned with the air outlet duct 3, thereby closing the airflow.

[0035] In this embodiment, the air outlet 7, when extended, functions the same as an existing bladeless fan and occupies the same space. However, when the air outlet 7 retracts into the housing 1, the space occupied by the air outlet 7 is reduced compared to existing bladeless fans. Furthermore, the volume of the packaging box and bag is reduced, especially for mass production, reducing packaging material consumption and thus lowering packaging costs. For transportation, the reduced transport volume allows for larger quantities to be transported at once, thereby lowering transportation costs.

[0036] Example 2:

[0037] This embodiment provides another type of bladeless fan with a lifting air outlet. The structure of Embodiment Two is largely the same as that of Embodiment One, except that it also includes a telescopic component. The air outlet 7 is slidably connected to the mounting cavity 8 via the telescopic component. Specifically, the telescopic component includes a telescopic tube 9, with both ends of the telescopic tube 9 connected between the air outlet 7 and the bottom wall of the mounting cavity 8. Due to the different specifications of the air outlet 7, this embodiment can provide two telescopic tubes 9, located on both sides of the mounting cavity 8. Alternatively, a single telescopic tube 9 can be provided, located in the middle of the mounting cavity 8. In actual use, the air outlet 7 is manually pulled out using the telescopic tube 9 to extend it; conversely, pressing down on the air outlet 7 and the telescopic tube 9 shortens and retracts them into the housing 1. An electric lifting device can also be used to drive the air outlet 7 for automatic upgrading.

[0038] Furthermore, the telescopic tube 9 is hollow, and its inner cavity connects the air outlet 7 and the air outlet duct 3. The telescopic tube 9 also functions as a conduit, guiding the airflow from the air outlet duct 3 to the air outlet 7. In other words, the telescopic tube 9 achieves a dual function: connecting the air outlet 7 and guiding the airflow.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
