Description

A ceiling fan Technical Field

[0001] The utility model relates to the field of fans, in particular to a ceiling fan. Background Art

[0002] The fan is used to blow air. In order to facilitate use and reduce space occupied, the fan can be hung on the ceiling to form a ceiling fan.

[0003] Specifically referring to Figure 1, the ceiling fan suspension structure currently used by the applicant generally uses a hollow hanging tube 1 as a load-bearing structure. In the design of the hanging tube, two through holes are opened on the side walls at the upper and lower ends of the hanging tube 1, and a single cross pin 1' is used as a structural connection between the upper and lower ends. Since the hollow hanging tube needs to pass the motor leads and the lamp leads (for ceiling fan lights), although the leads are slender, in order to facilitate the electrical connection of the leads, glue plugs 11' are usually provided at the ends of the leads. The setting of the cross pin 1' will block the two glue plugs 11' of the motor and lamp leads, so consumers need to perform secondary assembly of the hanging tube, that is, first remove the connection between the hanging ball 3 and the hanging tube 1, then pass the motor leads and lamp leads with glue plugs, and then assemble the hanging ball 3 and the hanging tube 1 again with the cross pin 1'. The assembly workload is large, and may cause consumers to have abnormal noise or poor swing of the fan due to poor assembly.

[0004] For this reason, it is necessary to improve and optimize the existing ceiling fan suspension structure.

DETAILED DESCRIPTION

[0043] To make the purpose, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is any conflict, the embodiments and features in the embodiments described below can be combined with each other in any manner.

[0044] Many different implementations or examples are provided below to implement the structure of the present invention.

[0045] Referring to Figures 2 to 15, an embodiment of the first aspect of the present invention provides a ceiling fan, including a hanging tube 1, which is generally a metal pipe to ensure that it has sufficient strength. The hanging tube 1 is hollow to form a wire hole 11; a fan body 2, which is connected and fixed to the lower end of the hanging tube 1. The specific connection method between the fan body 2 and the hanging tube 1 is a well-known technology in the art and will not be elaborated here. The fan body 2 can be a separate fan or can include a fan and a lighting assembly to form a fan lamp; a hanging ball 3, which is generally a metal part, is connected and fixed to the upper end of the hanging tube 1. The hanging ball 3 is provided with a sleeve hole 31, and the upper end of the hanging tube 1 is inserted into the sleeve hole 31. A pin 4 is provided on the side wall of the tube 1. There are multiple pins 4. In this embodiment, there are two pins 4 and they are arranged at 180°. The hanging tube 1 is suspended on the hanging ball 3 by the pin 4. The pin 4 does not extend into the wire hole 11. At this time, the pin can be welded to the outer wall of the hanging tube 1, or the pin can be integrally formed on the outer wall of the hanging tube 1. It can be understood that the pin can also be fixed to the outer wall of the hanging tube 1 by other well-known technologies. Since the pin 4 does not extend into the wire hole 11, there is obviously no problem of the pin blocking the wire glue insertion. Consumers can directly insert the wire glue through the wire hole 11 without disassembling the hanging ball and the hanging tube. In other embodiments, as shown in Figures 6, 7, and 14, the pin 4 extends into the wire hole 11 to form an insertion end, and the insertion ends of multiple pins 4 are spaced apart. In this embodiment, since two pins are used to replace the existing single cross pin structure shown in Figure 1, the insertion ends of the two pins 4 are spaced apart and do not contact each other. As a result, an avoidance space is formed between the insertion ends of the two pins, allowing the wire glue to be inserted through. Consumers can directly insert the wire glue through the wire hole without disassembling the hanging ball and the hanging tube.

[0046] As shown in Figures 6, 7 and 14, in some embodiments of the present invention, a pin hole is provided on the side wall of the hanging pipe 1, and the pin shaft 4 is riveted into the pin hole, which not only simplifies the structure of the hanging pipe 1 but also makes the connection of the pin shaft 4 on the hanging pipe reliable; in other embodiments, the pin shaft 4 can also be welded in the pin hole; thus, the pin shaft 4 and the hanging pipe 1 form a whole, which eliminates the process of installing the pin shaft for consumers, making the assembly of the ceiling fan simpler and faster.

[0047] Specifically referring to Figure 8, in some embodiments of the present invention, a U-shaped groove 32 is provided on the hole wall of the sleeve hole 31, and the pin 4 is placed in the U-shaped groove 32. The U-shaped groove 32 can guide and limit the pin 4, thereby facilitating the assembly of the hanging pipe 1 pre-installed with the pin 4 on the hanging ball 3, and the assembly position is accurate and the connection is reliable.

[0048] 6 and 9 , in some embodiments of the present invention, a screw hole 33 is provided on the wall of the sleeve hole 31. A screw 5 is provided in the screw hole 33. The screw 5 passes through the screw hole 33 and abuts against the outer wall of the hanging tube 1, tightening the hanging tube 1, thereby connecting the hanging tube 1 and the hanging ball 3 as a whole. As a result, after the hanging tube 1 is assembled on the hanging ball 3, it will not rotate or shake, ensuring stable rotation and air supply when the ceiling fan is in operation.

[0049] 10-13 and 15 and 16 , an embodiment of the second aspect of the present invention provides another ceiling fan, comprising a hanging tube 1, the hanging tube 1 being hollow to form a wire hole 11; a fan body 2, connected and fixed to the lower end of the hanging tube 1; a hanging ball 3, connected and fixed to the upper end of the hanging tube 1, the hanging ball 3 being provided with a sleeve hole 31, the upper end of the hanging tube 1 being inserted into the sleeve hole 31, the upper end of the hanging tube 1 being formed with an outer flange 14, the maximum radial dimension of the outer flange 14 being greater than the minimum radial dimension of the sleeve hole 31, and the hanging tube 1 being suspended on the hanging ball 3 through the outer flange 14.

[0050] Specifically referring to Figure 16, in some embodiments, the outer flange 14 is arranged perpendicular to the hanging tube 1, and the outer flange 14 abuts against the upper surface of the hanging ball 3. In this embodiment, the outer flange 14 is formed by extending the upper end tube wall of the hanging tube 1 outward by extruding the mold, and the outer flange 14 is used to abut against the upper surface of the hanging ball 3, thereby completing the suspension of the hanging tube 1 on the hanging ball 3; in other embodiments, specifically referring to Figures 10-13 and 15, the outer flange 14 is arranged obliquely to the hanging tube 1, so that the upper end outer wall of the hanging tube 1 is larger at the top and smaller at the bottom to form an oblique outer wall 12, and the sleeve hole 31 has an oblique inner wall 34 that is larger at the top and smaller at the bottom, and the oblique outer wall 12 is adapted to the oblique inner wall 34, and the hanging tube 1 is suspended on the hanging ball 3 by the cooperation of the oblique outer wall 12 and the oblique inner wall 34. In this embodiment, the upper end of the hanging tube 1 is expanded to form a large end, so that the sleeve 31 forms an axial limit on the upper end of the hanging tube 1, thereby completing the suspension of the hanging tube 1 on the hanging ball 3. As a result, the cross pin used in the existing structure is discarded, and the obstruction of the lead wire glue plug due to the presence of a single cross pin is completely avoided. Consumers can directly pass the lead wire and the glue plug on it through the wire hole 11 without having to disassemble the hanging ball and the hanging tube. According to the specific shape of the inclined inner wall 34 and the inclined outer wall 12, in this embodiment, the sleeve 31 forms a conical flare at the position of the inclined inner wall 34 and the hanging tube 1 forms a conical flare at the position of the inclined outer wall 12. The hanging tube 1 is suspended on the hanging ball 3 through the cooperation of the two conical flares. The two conical flares are tightly attached circumferentially, so that the connection of the hanging tube 1 to the hanging ball 3 is reliable and does not shake. The conical flare can be a conical inclined flare as shown in Figure 11, or a conical arc flare (not shown in the figure).

[0051] Specifically referring to Figures 10, 11, 13, 15 and 16, in some embodiments of the present invention, a screw hole 33 is provided on the sleeve hole 31, and a screw 5 is provided in the screw hole 33. The screw 5 passes through the screw hole 33 and is connected with the hanging pipe 1, so that the hanging pipe 1 and the hanging ball 3 are connected as a whole. The hanging pipe 1 will not loosen relative to the hanging ball 3, which facilitates the subsequent assembly process and is also convenient for transportation.

[0052] In some embodiments, the screw 5 is tightened against the hanging pipe 1, specifically against the oblique outer wall of the hanging pipe 1; in other embodiments, a hole 13 is provided on the hanging pipe 1 (specifically, the oblique outer wall shown in FIG11 , or the outer wall of the hanging pipe below the outer flange 14 shown in FIG16 ), and the screw 5 is inserted into the hole 13, so that the hanging pipe 1 is limited by the screw 5, thereby preventing the hanging pipe 1 from shaking or rotating relative to the hanging ball 3, thereby ensuring that the ceiling fan rotates smoothly and reliably.

[0053] Specifically referring to Figures 4 and 5, the ceiling fan also includes a hanger 6, which is provided with a hanging hole 61. The hanging pipe 1 passes through the hanging hole 61, and the hanging ball 3 on the hanging pipe 1 is axially limited in the hanging hole 61. Specifically, the maximum radial dimension of the hanging ball 3 is greater than the inner diameter of the hanging hole 61, so that the hanging ball 3 will not fall out of the hanging hole 61 from top to bottom. A limiting groove 35 is provided on the outer wall of the hanging ball 3, and a limiting block 62 is provided in the hanging hole 61. The limiting block 62 is inserted into the limiting groove 35 to limit the circumferential rotation of the hanging ball 3, thereby ensuring that the ceiling fan rotates smoothly and reliably.

[0054] From the above structural analysis, it can be seen that the embodiment of the present invention is to set the pin shaft 4 not to extend into the wire hole 11, or the pin shaft 4 is extended into the wire hole 11 to form an extending end, and the extending ends of multiple pin shafts 4 are spaced apart; or the upper end of the hanging tube 1 is formed with an outer flange 14, and the maximum radial dimension of the outer flange 14 is larger than the minimum radial dimension of the sleeve hole 31. The hanging tube 1 is suspended on the hanging ball 3 through the outer flange 14, abandoning the existing single cross pin structure, so that there is no cross pin passing through the wire hole of the hanging tube, thereby avoiding the presence of the cross pin to block the lead wire glue plug of the motor, etc. Therefore, when assembling, consumers do not need to disassemble the connection between the hanging ball and the hanging tube, and can directly pass the glue plug of the motor lead, etc. through the wire hole of the hanging tube, avoiding the secondary installation of consumers, and will not cause abnormal noise or poor swing of the fan due to poor assembly, thereby ensuring the reliability of the ceiling fan after installation, simple structure and low implementation cost.

[0055] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
