Description

Technical Field

[0001] The present invention relates to the technical field of invisible ceiling fan lamps, and in particular to an improved structure of an invisible ceiling fan lamp. Background Art

[0002] At present, ceiling fan lights have been widely used in various fields, especially for home use. It is a combination of a lamp and a ceiling fan, which has both the lighting and decorative functions of a lamp and the blowing effect of a fan. The best-selling ceiling fan light on the market is a kind of invisible ceiling fan light with hidden fan blades. The advantages of this ceiling fan light are: when the user does not use the fan to blow air, the fan blades will automatically retract and hide (store), which does not affect the appearance. When the user uses the fan function, the fan blades rotate with the storage tray and are thrown out under the action of centrifugal force, that is, the fan blades are unfolded.

[0003] In the existing invisible ceiling fan lamp, when the fan blades are stored on the storage tray, the front fan blade and the back fan blade partially overlap. The fan blade layout of the ceiling fan lamp with the above structure has the following shortcomings: (1) The overlapping fan blades make the overall height of the fan blades too large, and the packaging box is also large, which is not conducive to transportation; (2) When the overlapping fan blades are unfolded and stored, they are prone to friction, which not only generates noise but also damages the fan blades, affecting their service life. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and to provide a ceiling fan lamp with a simple and reasonable structure, no overlap between the fan blades, a small size, no friction between adjacent fan blades during unfolding and storage, no noise, and a long service life of the fan blades.

[0005] The object of the present invention is achieved in this way: an improved structure of an invisible ceiling fan lamp, comprising a storage tray and at least two fan blades, each fan blade comprising a root, a tip, a front edge and a rear edge, one end of the fan blade is the root, the other end is the tip, the front edge and the rear edge are respectively connected to the front side and the rear side between the root and the tip, the root of the fan blade is movably mounted on the storage tray, a motor connection portion is arranged in the center of the storage tray, and the characteristic is that when the fan blades are stored on the storage tray, the roots of the fan blades are evenly connected to the middle of the storage tray in a circumferential front and back order, and the front edge of the rear blade of the two adjacent fan blades is connected to the rear edge of the rear blade. The front edge of the rear fan blade goes around the root edge of the previous fan blade and then touches or is close to the rear edge of the previous fan blade. This invisible ceiling fan lamp is achieved by connecting the roots of the fan blades to the middle of the storage tray, and the front edge of the rear fan blade goes around the root edge of the previous fan blade and then touches or is close to the rear edge of the previous fan blade. In other words, the fan blades do not overlap and are all arranged on the storage tray. The overall height of the fan blades is small, and the packaging box is also small, which is convenient for transportation. In addition, since there is no overlapping part between the fan blades, the fan blades are not easy to rub and no noise will be generated when they are unfolded and stored, thereby avoiding damage to the fan blades. It has a long service life and a simple and reasonable structure.

[0006] The present invention can also be solved by the following technical measures:

[0007] Furthermore, the storage tray includes two to six fan blades, and each fan blade has the same shape and size, and each fan blade is approximately sickle-shaped. This sickle-shaped fan blade design makes full use of the storage tray area, so that the fan blades can be made as long as possible (it can also be an arc length) while the storage tray area remains unchanged, ensuring that the air volume remains unchanged and the fan blades do not overlap.

[0008] Furthermore, when the fan blades are stored on the storage tray, the front one-third to the front two-thirds of the length of the rear edge of each fan blade from the tip toward the root overlaps or is close to the outer edge of the storage tray, so that the fan blades are not exposed outside the storage tray as much as possible.

[0009] Furthermore, when the fan blades are stored on the storage tray, a straight line extending from the center of the storage tray toward the rear edge of the fan blade draws the largest width portion of the fan blade, and the rear edge portion of the rear edge starting from the largest width portion toward the top end of the fan blade coincides with or is close to the outer edge of the storage tray, thereby ensuring that the fan blade has a sufficiently long air supply area.

[0010] Furthermore, the motor connection portion is a circular groove, and the root of the rear fan blade is arranged on the storage tray between the front edge of the front fan blade and the motor connection portion, so that the root of the fan blade is connected to the middle of the storage tray.

[0011] Furthermore, the front edge and the rear edge extend outward from both sides of the root of the fan blade respectively. This root design is more conducive to the installation and rotation of the fan blade.

[0012] Furthermore, when the fan blades are stored on the storage tray, in a clockwise direction, the tip end of the rear fan blade extends to a starting position close to the rear edge of the front fan blade and close to the outer edge of the storage tray.

[0013] Furthermore, when the fan blade is stored on the storage tray, the tip end of the fan blade coincides with or is close to the outer edge of the storage tray.

[0014] The beneficial effects of the present invention are as follows:

[0015] (1) This invisible ceiling fan light is designed by connecting the roots of each blade to the middle of the storage tray, and the front edge of the rear blade goes around the root edge of the front blade and then touches or is close to the rear edge of the front blade. In other words, the blades do not overlap and are all arranged on the storage tray. The overall height of the blades is small, and the packaging box is also small, which is convenient for transportation. In addition, since there is no overlapping part between the blades, the blades are not easy to rub and generate noise when they are unfolded and stored, which avoids damage to the blades. It has a long service life and a simple and reasonable structure.

[0016] (2) Furthermore, this sickle-shaped fan blade design makes full use of the storage tray area, so that the fan blades can be made as long as possible (or the arc length) without changing the storage tray area, ensuring that the air volume remains unchanged while preventing the fan blades from overlapping.

[0017] (3) When the fan blades are stored on the storage tray, the front one-third to the front two-thirds of the length of the rear edge of each fan blade from the tip to the root are overlapped or close to the outer edge of the storage tray, so that the fan blades are not exposed outside the storage tray as much as possible.

[0018] (4) When the fan blade is stored on the storage tray, the straight line extending from the center of the storage tray toward the rear edge of the fan blade draws the largest width portion of the fan blade, and the rear edge portion of the rear edge starting from the largest width portion toward the tip of the fan blade coincides with or is close to the outer edge of the storage tray, thereby ensuring that the fan blade has a sufficiently long air supply area.
