[0002] A fan is a household appliance that uses an electric motor to rotate blades, accelerating air circulation, thereby achieving cooling or ventilation. It is widely used in homes, offices, classrooms, and other places to cool down and circulate air.

[0003] The season when fans are widely used is summer. When autumn and winter come, users will put the fans away. Most fans sold on the market now have fixed shapes and structures and occupy a large area. They are not easy to store for some small families. In order to solve this problem, some manufacturers have made foldable or detachable fans to facilitate users to store the fans when not in use. However, the fan's swing head structure still takes up a large area and affects the user's storage of the fan. In order to facilitate users to store fans, providing a new fan swing head structure is of practical value. Utility Model Content

[0004] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a fan swing head structure, which solves the problem that the existing fan swing head structure occupies a large space and affects the user's ability to store the fan.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a fan swing head structure, including a fan disc and a support assembly arranged on the back of the fan disc, the support assembly including a lower support part and an upper support part that are plugged into each other, and a cylinder that is plugged into the inner cavities of the lower support part and the upper support part, and a drive assembly is provided in the inner cavity of the cylinder; when the drive assembly is running, the drive end in the drive assembly engages with the swinging part, so that the cylinder drives the fan disc to move left or right.

[0006] Furthermore, the driving assembly includes a driving motor installed in the cylinder, the driving end is the output end of the driving motor, and the driving end extends into the upper support part.

[0007] Furthermore, the driving assembly also includes a gear sleeved on the driving end, and one side of the gear passes through the cylinder and engages with a tooth groove opened on the inner surface of the swing member in the upper support part.

[0008] Furthermore, the cylinder is conical and comprises an upper half and a lower half. The drive motor is located in the upper half, and the upper half overlaps with the top of the upper support portion.

[0009] Furthermore, the lower half is inserted from the inner cavity of the upper support part to the inner cavity of the lower support part, and a window is provided on a side of the lower half corresponding to the swinging part, and the gear part passes through the window and engages with the tooth groove.

[0010] Furthermore, the swinging member is in a semicircular arc shape, and a plurality of tooth grooves are provided on one side of the swinging member corresponding to the gear and are provided at equal intervals.

[0011] Furthermore, the lower end of the swinging member is connected to a limiting column, and the lower end of the limiting column is inserted into the lower supporting part through the inner cavity of the upper supporting part.

[0012] Furthermore, a connector is connected to the upper end of the cylinder, and the connector is connected to the lower part of the electric control box on the back of the fan disc.

[0029] Please refer to Figure 1-6 As shown, it shows the specific structure of the preferred first embodiment of the present invention, which is a fan swing head structure, including a fan disk 10 and a support assembly 20 arranged on the back of the fan disk 10, the support assembly 20 includes a lower support part 21 and an upper support part 22 that are plugged into each other, and a cylinder 2 that is plugged into the inner cavities of the lower support part 21 and the upper support part 22, and a driving assembly 23 is provided in the inner cavity of the cylinder 2; when the driving assembly 23 is running, the driving end a in the driving assembly 23 engages with the swinging member 232, so that the cylinder 2 drives the fan disk 10 to move left or right. Compared with the existing fan swing head structure, which controls the fan swing head through worm gear transmission, gear meshing transmission and crank rocker mechanism, the swing head structure of this fan is composed of a lower support part 21, an upper support part 22 and a cylinder 2. Through the operation of the driving assembly 23 in the cylinder, the driving end a drives the cylinder 2 to rotate by engaging with the swinging workpiece 232. The cylinder 2 drives the fan disk 10 to rotate left or right through rotation to complete the swing head action.

[0030] Specifically, the support assembly 20 is installed on the back of the fan disk 10, and the cylinder 2 that constitutes the support assembly 20 is inserted into the upper support part 22, and the upper support part 22 is inserted into the lower support part 21. The end of the lower support part 21 away from the upper support part 22 is connected to the base 30, thereby forming a complete fan; when the user needs the fan to swing its head, the drive assembly 23 in the cylinder 2 is started, so that the drive end a in the drive assembly 23 engages with the swinging member 232, so that the cylinder 2 turns left and right with the rotation direction of the drive end a, so that the fan disk 10 shakes left and right to facilitate the user to use the fan. In addition, the fan support assembly 20 composed of the cylinder 2, the upper support part 22, the lower support part 21 and the base 30 occupies a smaller area than the existing support structure, reducing the area occupied by the fan after the user stores the fan.

[0031] like Figure 4As shown, the drive assembly 23 exemplarily includes a drive motor 231 mounted within the barrel 2, with the drive end a being the output end of the drive motor 231, and the drive end a extending into the upper support portion 22. The drive motor 231 is mounted within the barrel 2, with the output end extending into the upper support portion 22. As the drive motor 231 operates, the upper rod of the drive motor 231 rotates, and the drive end a is located at the connection between the rod and the swinging member 232.

[0032] like Figure 5 As shown, the drive assembly 23 also includes a gear 233 that is sleeved on the drive end a. One side of the gear 233 extends through the barrel 2 and meshes with a tooth groove 2321 defined on the inner surface of the swing member 232 within the upper support portion 22. The gear 233 is sleeved and fixed to the rod at the output end of the drive motor 231 and meshes with the tooth groove 2321 defined on the inner surface of the swing member 232.

[0033] Specifically, the conventional operation mode of this transmission structure is that as the drive motor 231 operates, the gear 233 rotates accordingly, driving the swing member 232 to rotate. Although this driving mode is convenient, the drive motor 231 needs to be installed below the cylinder 2 connected to the fan disk 10. This mode requires a high degree of connection between the cylinder 2 and the upper support portion 22, resulting in difficulty in disassembling the cylinder 2 and the upper support portion 22 when the drive motor 231 is damaged. Therefore, in the swing head structure of the present fan, by installing the drive motor 231 in the cylinder 2 located above the upper support portion 22, and the cylinder 2 passes through the inner cavity of the upper support portion 22 to the lower support portion 21, the cylinder 2 rotates within the inner cavities of the upper support portion 22 and the lower support portion 21 as the gear 233 and the tooth groove 2321 engage. Compared with the conventional connection mode, this mode is more stable because the cylinder 2 has sufficient length, and the entire swing head structure of the fan is smaller.

[0034] like Figure 5 As shown, for example, the cylinder 2 is in a conical shape and includes an upper half 2a and a lower half 2b. The drive motor 231 is located in the upper half 2a, and the upper half 2a overlaps the top of the upper support portion 22. Because the cylinder 2 is configured in a conical shape, it is easier for the cylinder 2 to pass from the inner cavity of the upper support portion 22 to the lower support portion 21. In addition, in order to make the surface of the cylinder 2 parallel to the upper support portion 22 and the lower support portion 21, thereby increasing the aesthetics of the entire fan, the cylinder 2 is divided into an upper half 2a and a lower half 2b. The upper half 2a is inserted into the inner cavity of the upper support portion 22, and the outer wall of the upper half 2a is parallel to the outer walls of the upper support portion 22 and the lower support portion 21, while the lower half 2b is in a conical shape.

[0035] like Figure 6As shown, for example, the lower portion 2b is inserted from the inner cavity of the upper support portion 22 to the inner cavity of the lower support portion 21, and a window 2c is provided on the side of the lower portion 2b corresponding to the swinging member 232, through which the gear 233 partially passes and meshes with the tooth groove 2321. The driving motor 231 is located in the inner cavity of the upper portion 2a, and the output end of the driving motor 231 is inserted into the inner cavity of the lower portion 2b. At this time, the gear 233 on the rod body at the output end of the driving motor 231 is located in the inner cavity of the lower portion 2b. At this time, to facilitate the meshing of the gear 233 with the tooth groove 2321, a window 2c is provided on one side of the lower portion 2b. A portion of the gear 233 passes through the window 2c and meshes with the tooth groove 2321, so that the movement of the gear 233 on the tooth groove 2321 can drive the movement of the cylinder 2.

[0036] like Figure 1 As shown, the swing member 232 is exemplarily semicircular in shape, and the swing member 232 has multiple equally spaced tooth grooves 2321 on one side of the swing member 232 corresponding to the gear 233. By configuring the swing member 232 in a semicircular shape, the gear 233 rotates in a manner and at an angle consistent with conventional fans, preventing the barrel 2 from rotating excessively and potentially damaging the wiring harness connected to the bottom end of the barrel 2.

[0037] like Figure 3 As shown, for example, the lower end of the swing member 232 is connected to the limiting post 24, and the lower end of the limiting post 24 is inserted into the lower support part 21 through the inner cavity of the upper support part 22. The limiting post 24 and the swing member 232 are connected by screws, and the connection between the limiting post 24 and the swing member 232 is adapted so that the lower half of the cylinder 2 can be inserted into the limiting post 24. The limiting post 24 is fixed to the lower support part 21 by screws. At this time, the swing member 232 connected to the limiting post 24 is limited and cannot rotate under the drive of the gear 233. The gear 233 is installed in the cylinder 2, and the cylinder 2 is plugged into the lower support part 21 and the upper support part 22, so that the gear 233 can drive the cylinder 2 to rotate by meshing with the tooth groove 2321 on the swing member 232, so that the fan disc 10 rotates left and right.

[0038] It should be noted that this connection method can facilitate the separation of the cylinder 2 from the upper support portion 22 and the lower support portion 21 while effectively ensuring the stability of the cylinder 2 and the fan disc 10 installed on the cylinder 2.

[0039] like Figure 3 As shown, for example, a connector 3 is connected to the upper end of the cylinder 2. This connector 3 connects to the lower portion of the electrical control box 4 on the back of the fan disk 10. Connector 3 engages with connecting rods 41 in the electrical control box 4 via connecting holes 31 on either side of the upper portion. Connector 3 is mounted on the cylinder 2, and connecting holes 31 are provided on either side of the end of the connector 3 facing away from the cylinder 2. These holes 31 engage with connecting rods 41 in the electrical control box 4, enabling the fan disk 10 to be adjusted up and down.

[0040] The lower support part 21 is a column and contains multiple lower support parts 21. The multiple lower support parts 21 can be connected to each other through threads. When the lower support part 21 is a column and contains multiple lower support parts, the user can reduce the height difference between the fan disc 10 and the user's height according to his or her own usage needs to facilitate user use.

[0041] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
