DETAILED DESCRIPTION

[0025] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0026] refer to Figures 1 to 6

[0027] A handheld fan with a hidden supporting mechanism comprises a fan housing 10, wherein a fan assembly 20 capable of flipping over to change the air outlet direction is arranged on the upper portion of the fan housing; an arc plate 30 is arranged on the upper rear side of the fan housing, the two ends of which are hinged to the fan housing and used for support after flipping; the arc plate fits with the fan housing when stored, thereby improving the aesthetics and reducing the occupied space.

[0028] In this embodiment, a front concave step surface 11 for accommodating the arc plate is provided on the upper rear side of the fan housing, so that when the arc plate is stored, it fits with the front concave step surface, so that the arc plate and the fan housing are integrated, which improves the aesthetics and reduces the occupied space.

[0029] In this embodiment, hinge shafts 31 are transversely arranged on the inner sides of both ends of the arc plate, and the hinge shafts are hinged to the hinge holes 12 on the side walls of the front concave step surface of the fan housing, thereby realizing the flipping of the arc plate.

[0030] In this embodiment, in order to control the rotation angle of the arc plate, a passing point limit mechanism for the arc plate flipping is provided on the fan housing, and the passing point limit mechanism includes a step side wall 13 formed after a front concave step surface is set on the rear side of the upper part of the fan housing, and a passing point limit ridge 14 is provided on the front concave step surface located on the front side of the end of the arc plate, and a front groove 15 is provided on the front concave step surface at the lower side of the passing point limit ridge, so that after the end of the arc plate flips over the limiting ridge, the end corner of the arc plate sinks into the front groove for positioning, and the rear side surface of the arc plate rests on the step side wall.

[0031] In this embodiment, in order to prevent the arc plate from shaking when it is accommodated and attached to the front concave step surface of the fan housing, the arc plate is provided with a clamping structure when it is attached to the fan housing, and the clamping structure includes a front convex column 32 provided at the front side of the lower end of the arc plate, and a front concave portion 16 for the front convex column to extend into is provided at the rear side of the upper part of the fan housing and at the lower part of the front concave step surface, and a spring piece 17 for clamping the front convex column is provided in the front concave portion. Thus, the front convex column is clamped by the spring piece, so that the arc plate does not shake.

[0032] In this embodiment, the fan housing, the arc-shaped plate, etc. may be plastic parts; the structure of the spring piece may be V-shaped and a convex portion protruding outward is provided at the cantilever end to better clamp the front boss.

[0033] In this embodiment, in order to facilitate the flipping of the arc plate, a turning protrusion 33 is provided at the lower part of the arc plate, so that the user can turn the arc plate outward by turning the protrusion to disengage the front protrusion from the spring sheet, thereby realizing the subsequent flipping of the arc plate.

[0034] In this embodiment, in order to facilitate the rotation of the fan assembly, a rotating shaft 21 rotatably connected to the fan housing is transversely arranged on both sides of the fan assembly, an axial hole matched with the rotating shaft is arranged on the fan housing, and a soft material 22 having rotation damping is arranged on the circumferential surface of the rotating shaft to cooperate with the rotating part of the fan housing to form a rotation damping, so that the fan assembly can be positioned after rotation and maintained at a desired angle. The soft material can be a silicone ring or a rubber ring, and the soft material can be sleeved on the rotating shaft and interference fit, and the outer ring is clamped or interference fit with the axial hole on the fan housing, so that the fan assembly has rotation damping when rotating.

[0035] In this embodiment, in order to prevent the fan assembly from rotating 360° around the fan housing and breaking the wire of the fan assembly, a flip angle limiting mechanism is provided between the fan assembly and the fan housing, and the flip angle limiting mechanism includes a convex shaft 23 which is transversely arranged at the end of the rotating shaft and protrudes outward, and a radial convex portion 24 is provided on the convex shaft, and a limiting convex portion 18 for rotation limiting of the radial convex portion is provided on the fan housing. When the radial convex portion rotates to abut against the limiting convex portion, the fan assembly can no longer rotate.

[0036] In this embodiment, in order to reduce the wear of the fan housing and prevent the handheld fan from sliding when it is tilted and placed on the desktop (the arc plate is unfolded), an anti-slip pad 19 is provided on the rear side of the lower part of the fan housing, and the anti-slip pad is a silicone pad.

[0037] When the handheld fan stands on the desktop, the wind angle can be changed by rotating the fan assembly, and the fan assembly can be turned around the rotating shaft 180 degrees to change direction. At the same time, when the handheld fan is placed on the desktop, the fan can be tilted and supported on the desktop by rotating the curved plate, and the wind direction can be adjusted by rotating the fan assembly. When the curved plate is stored, it can be attached to the front concave step surface, effectively reducing the occupied space, improving the aesthetics, and making the structure more compact.

[0038] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection to each other can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0039] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0040] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0041] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
