DETAILED DESCRIPTION

[0029] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0030] As attached Figure 1 To the attached Figure 8 As shown:

[0031] Example 1: According to Figure 1 、 Figure 5 and Figure 6As shown, the present invention provides a two-season fan with an adjustment function, including a support base 1, an adjustment component is provided on the top of the support base 1, and the adjustment component includes a connecting screw 2, the connecting screw 2 is fixedly connected to the middle part of the top of the support base 1, the outer wall of the connecting screw 2 is threadedly connected to an extension rod 3, the top of the extension rod 3 is fixedly connected to a connecting screw 2 4, and the top of the connecting screw 2 4 is threadedly connected to an extension rod 2 5. By rotating the extension rod 1 3 and the extension rod 2 5, the user can easily adjust the total length of the support rod, thereby realizing the use of the fan at two different heights on the table or on the ground, thereby improving the flexibility of the fan.

[0032] Example 2: According to Figure 1 、 Figure 3 and Figure 5 As shown, the drive assembly includes a drive motor 14, the drive motor 14 is mounted on the inner side wall of the extension rod 2 5, the drive motor 14 is provided with an anti-dump switch 13 near the bottom, the top of the extension rod 2 5 is also provided with a rotating head 6, the output end of the drive motor 14 is connected to the rotating head 6, the outer side of the rotating head 6 is provided with a connecting shaft 7, the outer side wall of the connecting shaft 7 is provided with a fan body, the fan body includes a fan housing 8, the fan housing 8 is mounted on the outer side wall of the connecting shaft 7 and is rotatably connected to the output end of the rotating head 6, the fan housing 8 also has a built-in fan blade assembly 10, the output end of the drive motor 14 is fixedly connected with a gear Wheel 15, two retaining springs 16 and bearings 17 are provided on the inner side of the extension rod 2 5, and a rotating rod 19 is provided near the inner side of the two retaining springs 16 and the bearings 17. The outer side of the gear 15 is meshed with the rotating rod 19 and connected together. An up and down shaking motor 18 is installed at the input end of the fan blade assembly 10. The up and down shaking motor 18 is used to drive the fan housing 8 to rotate it up and down. When the rotating head 6 is started, it will drive the fan housing 8 and the fan blade assembly 10 to rotate together through the connecting shaft 7, thereby generating wind flow and achieving the purpose of regulating air flow. By setting the anti-dumping switch 13, the switch can be controlled to be closed when the fan dumps, to avoid continuing to work after dumping;

[0033] By driving the gear 15 at the output end of the motor 14 to rotate, the rotational force is transmitted to the gear inside the rotating rod 19, so that the top of the rotating rod 19 drives the rotating head 6 to swing, and the upper and lower bearings 17 are limited by the retaining spring 16. The bearings 17 are restricted from shaking by the inner wall of the extension rod 2 5. The rotating rod 19 is connected to the front and rear concave and convex grooves of the liner to keep it upright.

[0034] Example 3: According to Figure 1 and Figure 3As shown, a filtering mechanism is provided in the fan body, and the filtering mechanism includes a filter cover 9. The filter cover 9 is provided on one side wall outside the fan casing 8. The other side wall outside the fan casing 8 is also provided with an air outlet 12. The filter cover 9 can perform preliminary filtering on the air entering the fan to remove large particles of impurities in the air.

[0035] Example 4: According to Figure 1 and Figure 3 As shown, the fan body also includes a heating component, which includes a heating wire 11. The heating wire 11 is installed on the inner wall of the fan housing 8. Two insulation boards are also provided on both side walls of the heating wire 11. The insulation boards are made of high-temperature resistant mica boards, which can effectively prevent heat leakage and improve heating efficiency. The heating wire 11 is made of iron-chromium-aluminum alloy with a thermal efficiency of ≥99%, and can maintain a stable heating efficiency throughout the service life of the product. When the heating function is required, the user can turn on the switch of the heating wire 11, and the heating wire 11 will generate heat and transfer the heat to the air through the wind flow of the fan to achieve the purpose of heating the air.

[0036] Working principle: When this device is needed, if it needs to be installed on the table, first separate the support base 1 and the extension rod 3 through the connecting screw 2, and then separate the extension rod 2 5 and the extension rod 3 through the connecting screw 2 4, and then insert the extension rod 2 5 into the position of the connecting screw 2 and thread them together. By turning on the switch of the drive motor 14, the drive motor 14 can rotate with the rotating rod 19 through the gear 15, so that it can swing left and right. By shaking the motor 18 up and down, the fan housing 8 can be controlled to swing up and down to sweep the wind. Then the fan blade assembly 10 works and can inhale air from the filter cover 9. The filter cover 9 can filter the incoming air and enter the position of the heating wire 11 through the fan blade assembly 10. The heating wire 11 heats the air and then discharges it through the air outlet 12. When heating is not needed, the switch of the heating wire 11 can be turned off for use.
