Abstract
Description
field of technology
[0001] The present application relates to the technical field of bladeless fans, in particular a foldable and collapsible bladeless fan that can be easily disassembled. State of the art
[0002] A bladeless fan, also known as an air amplifier, creates a natural and continuous flow of cool air. Because it has no rotor blades, it doesn't collect dust and can't cause injury from children's fingers. Its unusual shape, with a streamlined yet elegant appearance, is particularly noteworthy.
[0003] However, according to the current state of the art, bladeless fans have the following disadvantages: Non-foldable: In conventional bladeless fans, the air outlet ring and the base are often permanently connected, resulting in a large overall volume. They take up a lot of space when stored and are neither easy to transport nor space-saving to store (e.g., for seasonal storage in the home, during transport, or when used in small apartments).
[0004] Limited air outlet angle: Most bladeless fans can only adjust the air outlet angle by horizontal rotation, without allowing adjustment of the tilt angle (up or down). This makes it difficult to implement various application scenarios (such as direct airflow onto a tabletop or supplying air to higher areas).
[0005] Insufficient structural stability: In some bladeless fans with adjustable angles, the connecting structure tends to loosen after repeated adjustments, leading to unstable angle fixation and impairing ease of use.
[0006] Difficult maintenance of the air outlet: When the air outlet needs to be replaced or cleaned, it is often necessary to completely disassemble the device in order to separate the U-shaped air outlet pipe, which is very cumbersome. Content of the utility model
[0007] Against this background, it is necessary to provide a foldable and easily disassemblable bladeless fan to address the aforementioned problems, which is both foldable to save space and allows flexible adjustment of the tilt angles for upward and downward airflow, and which has a stable structure.

An elastic detent is arranged on each of the two side faces of the upper half-tube, and a detent receptacle is formed on the inside of the arcuate groove; and a connecting assembly, wherein the connecting assembly is movably clipped into the interior of the air outlet openings and connected to the main fan body housing, one end of the connecting assembly extends outwards beyond the main fan body housing, and a U-shaped air outlet pipe is movably connected to the outside of the connecting assembly.
[0009] In one embodiment, the connecting assembly comprises a movable circular disk and an arcuate plate, wherein the arcuate plate is fixedly attached to the lower end face of the movable circular disk, one end of the movable circular disk is movably clipped into the interior of the air outlet opening, and the arcuate plate is clipped into the interior of the snap-fit receptacle through the interior of the arcuate groove.
[0010] In one embodiment, the connecting assembly further comprises a rotary groove and an annular groove, wherein the elastic detents are each movably clipped into the interior of the rotary groove, the elastic detents each have an arcuate surface, the rotary groove has an annular groove on the side facing the U-shaped air outlet pipe, and one side of the annular groove is movably clipped into the interior of the U-shaped air outlet pipe.
[0011] In one embodiment, the U-shaped air outlet pipe comprises a front cover, a rear cover and a mounting ring plate, wherein the front cover and the rear cover each have a semicircular opening at their end sections, and one end of the annular groove of the movable circular disc is movably clipped into the interior of the semicircular opening.
[0012] In one embodiment, the U-shaped air outlet pipe further comprises a frame detent, air outlet openings and plug-in detents, wherein the rear cover has several frame detents on the inside of the side facing the front cover, the front cover has several plug-in detents on the side facing the rear cover, the plug-in detents are each movably clipped into the interior of the frame detents, and the front cover has several air outlet openings on its front side.
[0013] In one embodiment, an air-generating assembly is arranged inside the main body of the fan, wherein the air-generating assembly has a protective housing at its upper end, the air-generating assembly has a filter at its lower end, the air-generating assembly includes a servo motor inside, the output of the servo motor is connected to an ultra-quiet fan wheel via a coupling, and the ultra-quiet fan wheel is movably clipped into the interior of the protective housing.
[0014] In one embodiment, the U-shaped air outlet pipe has a mounting device at each of its upper and lower ends, wherein the mounting device comprises a handle, a receiving groove, a threaded rod, a receiving bore and a threaded hole, the front cover and the rear cover each have a handle firmly attached to their upper and lower end faces, the handles each have a receiving groove on their outer surface, the handles each have a threaded hole, a threaded rod is screwed into each of the threaded holes, and the handles each have a receiving bore at their ends, wherein the receiving bore is appropriately connected to the surface of the threaded rod.
[0015] In one embodiment, a lower half-pipe is arranged inside the main fan body housing, wherein the lower half-pipe is connected to the upper half-pipe by screws, and the two ends of the lower half-pipe are each movably clipped into the interior of the air outlet openings.
[0016] In one embodiment, a base assembly is rotatably mounted at the lower end of the fan body, wherein the base assembly comprises a lower base, a bearing and an air inlet opening, the lower end of the fan body housing is rotatably connected to the upper end of the lower base, a bearing is arranged at the connection point between the upper end of the lower base and the fan body housing, and an air inlet opening is formed on the outside of the lower end of the bearing.
[0017] In one embodiment, an operating panel is arranged on the outer surface of the main fan body housing, and a top cover is arranged on the top of the main fan body housing.
[0018] In the above-described foldable and easily disassemblable bladeless fan, the interaction of the U-shaped air outlet pipe with the connecting assembly allows the U-shaped air outlet pipe and the connecting assembly to be rotated at the air outlet openings, enabling the U-shaped air outlet pipe to rotate around the central axis of the connecting assembly. This allows the device to be assembled in a foldable and collapsible manner, which facilitates its storage.
[0019] The interaction of the curved groove with the curved plate allows the curved plate to be aligned with the curved groove during use; subsequently, the front and rear covers can be pulled outwards, allowing the covers, along with the connecting assembly, to be removed from inside the air outlet openings. This enables easy disassembly and assembly of the device, facilitates maintenance, and simplifies transport and storage.
[0020] The interaction of the handles with the mounting grooves allows the left and right handles to be connected via these grooves during the installation of the front and rear covers. The threaded rod is then inserted into the threaded hole, screwing and securing the front and rear handles together. This prevents the front and rear covers from being pulled outwards by gravity or other forces when the U-shaped air outlet pipe is rotated, thus preventing unintentional disassembly.
