[0026] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed embodiments of the present invention in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0027] As Figures 1 to 3As shown, in one embodiment, a fan head assembly 10 is provided, comprising a shaft sleeve 11 and an adjustment box 12. The adjustment box 12 is provided with a mounting tube 1211 for being mutually sleeved with the shaft sleeve 11. The side wall of the adjustment box 12 is provided with a first wiring hole 1212. The shaft sleeve 11 is provided with a pressing member 13, and a wiring channel 111 is provided between the pressing member 13 and the shaft sleeve 11. Figure 2 As shown, when the sleeve 11 and the mounting tube 1211 are assembled in place, the first wiring hole 1212 is provided on the side wall of the regulating box 12 and is located on the side of the pressing member 13 away from the wiring channel 111, and the first wiring hole 1212 is located between the entrance and the exit of the wiring channel 111.

[0028] The above scheme provides a fan head assembly 10, wherein the first wiring hole 1212 and the wiring channel 111 are used for the power cord 20 to pass through. Based on the fact that the first wiring hole 1212 is provided on the side wall of the regulating box 12, it is located on the side of the pressing member 13 away from the wiring channel 111, and the first wiring hole 1212 is located between the entrance and exit of the wiring channel 111. Therefore, during the assembly process, the forward direction of the power cord 20 from the first wiring hole 1212 to the entrance of the wiring channel 111 is different from the forward direction from the entrance to the exit of the wiring channel 111, so that Figure 2 As shown, the end of the power cord 20 on the pressing member 13, near the entrance of the wiring channel 111, is pressed and bent by the pressing member 13. This creates significant friction between the power cord 20, the pressing member 13, and the sidewalls of the adjustment box 12, securing the power cord 20. As the shaft sleeve 11 is assembled with the mounting barrel 1211, it also secures the power cord 20, improving overall assembly efficiency.

[0029] Specifically, if Figure 3 As shown, during the assembly process, the power cord 20 is first inserted into the regulating box 12 through the first wiring hole 1212, and then inserted into the wiring channel 111 from bottom to top. Then the sleeve 11 is inserted into the regulating box 12 from the open end of the regulating box 12 and assembled to the mounting cylinder 1211. Figure 1 and Figure 2 As shown, the pressing member 13 extends to the side of the first wiring hole 1212 away from the opening of the regulating box 12, so that the power cord 20 will be bent at the first wiring hole 1212 and at the entrance of the wiring channel 111, so that there is a large friction force between the power cord 20 and the regulating box 12 and the pressing member 13, which plays a role in fixing the power cord 20.

[0030] Furthermore, in one embodiment, Figures 1 to 3As shown, the bushing 11 and the mounting cylinder 1211 are snap-fitted. Thus, after the bushing 11 and the mounting cylinder 1211 are properly fitted, without releasing the snap connection between them, the pressing member 13 and the bushing 11 are both fixed in the adjustment box 12, and the power cord 20 is pressed and fixed in the adjustment box 12.

[0031] Specifically, as Figures 2 to 4 shown, in one embodiment, the side wall of the bushing 11 is provided with a snap 112, and a bayonet is provided at a position corresponding to the snap 112 on the mounting cylinder 1211. When the bushing 11 is installed in the mounting cylinder 1211, the snap 112 is stuck in the bayonet, so that the bushing 11 and the mounting cylinder 1211 are snap-fitted.

[0032] More specifically, after the bushing 11 and the mounting cylinder 1211 are assembled, the support spindle of the main motor of the electric fan can be inserted therein to support the main motor. And the power cord 20 can be electrically connected to the main motor.

[0033] To facilitate the contact between the power cord 20 and the main motor, in one embodiment, as Figure 2 shown, the wire routing channel 111 is arranged along the axial direction of the bushing 11. The outlet of the wire routing channel 111 is located near the opening of the adjustment box 12, so that the power cord 20 arranged in the wire routing channel 111 just extends to a position near the main motor.

[0034] Optionally, in other embodiments, the wire routing channel 111 can also be arranged in other directions, which is not specifically limited here.

[0035] Furthermore, as Figure 4 shown, a cantilever 14 is further provided outside the bushing. A support column (not shown in the figure) for assembling the connecting rod is provided on the adjustment box. One end of the connecting rod is rotatably connected to the support column, and the other end of the connecting rod is rotatably connected to a crank on the swing motor of the machine head. One end of the cantilever 14 far from the bushing 11 is used to limit the connecting rod on the support column.

[0036] Furthermore, the bushing 11 and the mounting cylinder 1211 can be such that the bushing 11 is inserted into the mounting cylinder 1211, or the bushing 11 is sleeved outside the mounting cylinder 1211.

[0037] Specifically, when the bushing 11 is inserted into the mounting cylinder 1211, as Figure 2As shown, the pressing member 13 is located between the mounting tube 1211 and the side wall of the regulating box 12 , and the pressing member 13 and the mounting tube 1211 are arranged at intervals, and the power cord 20 arranged in the wiring channel 111 is located between the pressing member 13 and the mounting tube 1211 .

[0038] When the sleeve 11 is sleeved outside the mounting tube 1211 , the pressing member 13 is located between the sleeve 11 and the side wall of the regulating box 12 , and the power line 20 arranged in the wiring channel 111 is located between the pressing member 13 and the sleeve 11 .

[0039] When the sleeve 11 is sleeved on the outside of the mounting tube 1211, the pressing member 13 can be a raised block-shaped structure provided on the outside of the sleeve 11, and the wiring channel 111 is a channel formed in the pressing member 13. Moreover, the raised block-shaped structure can fully squeeze the power line 20 located between the side wall of the adjustment box 12 and the pressing member 13, thereby improving the fixing effect.

[0040] More specifically, in one embodiment, Figure 4 As shown, the pressing member 13 includes a pressing plate 131 and a connecting portion 132. The pressing plate 131 is arranged along the axial direction of the shaft sleeve 11, and the spacing between the pressing plate 131 and the shaft sleeve 11 forms the wiring channel 111 arranged along the axial direction of the shaft sleeve 11. The connecting portion 132 connects the pressing plate 131 and the shaft sleeve 11, and the connecting portion 132 is provided with a second wiring hole 1321 that is connected to the wiring channel 111. The power cord 20 passes through the second wiring hole 1321 when passing through the wiring channel 111. The portion where the first wiring hole 1212 is provided on the side wall of the regulating box 12 is located on the side of the pressing plate 131 away from the wiring channel 111.

[0041] like Figure 2 As shown, when the power cord 20 is squeezed in the regulating box 12, the power cord 20 located between the first wiring hole 1212 and the entrance of the wiring channel 111 is distributed on the pressure plate 131 and the side wall bracket of the regulating box 12, and the part of the pressure plate 131 that constitutes the entrance of the wiring channel 111 presses against the power cord 20, changes the direction of the power cord 20, and provides friction for the power cord 20.

[0042] Furthermore, in one embodiment, Figure 2 As shown, the shaft sleeve 11 is inserted into the mounting tube 1211. The pressing plate 131 is located between the mounting tube 1211 and the side wall of the regulating box 12. The pressing plate 131 and the mounting tube 1211 are spaced apart, and the power line 20 arranged in the wiring channel 111 is located between the pressing plate 131 and the mounting tube 1211.

[0043] The spacing space between the mounting cylinder 1211 and the side wall of the adjustment box 12 is limited. After the pressing plate 131 divides the limited space into two parts, when the power cord 20 winds therein, the bending is obvious, the frictional force received is large, and the fixing effect is better.

[0044] Further, in another embodiment, the part of the sleeve 11 inserted into the mounting cylinder 1211 first is the head, and the connecting portion 132 is located at the tail of the sleeve 11. Thus, the setting of the connecting portion 132 will not hinder the insertion of the sleeve 11 into the mounting cylinder 1211.

[0045] Alternatively, in yet another embodiment, the mounting cylinder 1211 is provided with a relief notch arranged along its own axial direction, and the connecting portion 132 passes through the relief notch to connect the sleeve 11 and the pressing plate 131. The setting of the relief notch provides a relief space for the connecting portion 132 to ensure that the sleeve 11 can be completely inserted into the mounting cylinder 1211. During the process of the sleeve 11 being inserted into the mounting cylinder 1211, the connecting portion 132 moves in the relief notch.

[0046] Further, in one embodiment, the sleeve 11 is sleeved outside the mounting cylinder 1211, and the pressing plate 131 is located between the sleeve 11 and the side wall of the adjustment box 12. At this time, the power cord 20 is pressed between the pressing plate 131 and the side wall of the adjustment box 12, and between the pressing plate 131 and the sleeve 11.

[0047] More specifically, as Figure 4 shown, in one embodiment, the pressing member 13 further includes a first side plate 133 and a second side plate both arranged along the axial direction of the sleeve 11. The first side plate 133 and the second side plate are respectively located on the left and right sides of the pressing plate 131, and both the first side plate 133 and the second side plate are connected to the pressing plate 131 and extend to the side of the pressing plate 131 close to the sleeve 11.

[0048] As Figure 4As shown, the first side plate 133, the second side plate, the pressing plate 131 and the bushing 11 together enclose the wire routing channel 111, and the first side plate 133 and the second side plate can limit the power cord 20 within the wire routing channel 111. Specifically, the bushing 11 and the pressing plate 131 are positioned on the inner and outer sides of the power cord 20, and the first side plate 133 and the second side plate are positioned on the left and right sides of the power cord 20. It should be noted that although both the first side plate 133 and the second side plate extend to the side of the pressing plate 131 close to the bushing 11, the first side plate 133 and the second side plate do not contact the bushing 11. In other words, there is a gap for accommodating the mounting cylinder 1211 between the first side plate 133 and the bushing 11, and there is also a gap for accommodating the mounting cylinder 1211 between the second side plate and the bushing 11. Thus, when the bushing 11 is inserted into the mounting cylinder 1211, the first side plate 133, the second side plate and the pressing plate 131 can all be located outside the mounting cylinder 1211.

[0049] More specifically, in one embodiment, as Figure 5 shown, the adjustment box 12 includes a cylindrical barrel-shaped main body portion 121 and a hinge portion 122 located at the bottom of the main body portion 121. The mounting cylinder 1211 is located within the main body portion 121, the mounting cylinder 1211 is coaxially arranged with the main body portion 121, and the first wire hole 1212 is provided on the side wall of the main body portion 121.

[0050] The bushing 11 is inserted into the main body portion 121 from the open end of the main body portion 121 and cooperates with the mounting cylinder 1211, and the pressing member 13 is located between the side wall of the main body portion 121 and the bushing 11. The main motor is provided on the open end of the main body portion 121.

[0051] When the bushing 11 is inserted into the mounting cylinder 1211, as Figure 2 shown, the pressing plate 131 is located between the mounting cylinder 1211 and the side wall of the main body portion 121.

[0052] The hinge portion 122 is used for rotatably connecting with the fuselage to adjust the orientation of the main motor. The main motor can also swing relative to the adjustment box 12, and during the swinging process, the support main shaft of the main motor is supported in the bushing 11 and rotates within the bushing 11. The specific swinging process is realized by the crank and connecting rod mechanism composed of the swing motor and the connecting rod.

[0053] Furthermore, in another embodiment, an electric fan is provided, which includes a power cord 20 and the above-mentioned fan head assembly 10, and the power cord 20 is arranged along the first wire hole 1212 and the wire routing channel 111.

[0054] An electric fan provided by the above solution, by adopting the fan head assembly 10 described in any of the above embodiments, during the assembly process, while the bushing 11 and the mounting cylinder 1211 are assembled, the power cord 20 can be fixed by means of the pressing member 13, improving the assembly efficiency.

[0055] Further, in one embodiment, the electric fan further includes a main motor and a body, and the support main shaft of the main motor is inserted into the mounting cylinder 1211 and the bushing 11. Specifically, when the bushing 11 is inserted into the mounting cylinder 1211, the support main shaft is inserted into the bushing 11; when the bushing 11 is sleeved outside the mounting cylinder 1211, the support main shaft is inserted into the mounting cylinder 1211. The power cord 20 is electrically connected to the main motor, and the adjustment box 12 is rotatably arranged on the top of the body.
