For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0035] As described in the background technology, fans are commonly used household appliances that can accelerate air circulation and improve living and working environments. In the prior art, fans are generally powered directly by the mains, but this power supply method has limited usage scenarios. It can only be used indoors or near a socket, and cannot be used in situations such as power outages or insufficient sockets.

[0036] In this regard, some fans can be powered by mobile power or other means, and accordingly, a corresponding interface will be set on the back or column of the fan head. However, the setting method of this interface may hinder the normal implementation of this power supply method due to factors such as the length of the mobile power transmission line or the height of the interface, affecting the user's experience. In addition, in different usage scenarios, in order to improve the user's experience, higher requirements will be placed on the appearance of the fan, such as the layout of buttons and interfaces, or the practicality of the fan, such as dust and water resistance of the interface.

[0037] In order to solve the problem of affecting user experience caused by the interface arrangement of existing fans, the present application provides a fan, comprising a fan head (10), a support part (20), a control part and an interface module (30), wherein the support part (20) comprises a support rod (21) and a base (22), the top end of the support rod (21) is connected to the fan head (10), the bottom end of the support rod (22) is connected to the base (22), and a placement groove (221) is provided on the base (22); the control part comprises a control board and a power board, and the control board is respectively connected to the motor and the power board; the interface module (30) is provided with an external power supply interface for connecting to the power board, and the interface module (30) can be movably arranged in the placement groove (221) so that the external power supply interface is exposed or hidden in the placement groove (221).

[0038] When the above technical solution is adopted, when a mobile power supply is used for power supply, regardless of the length of the power cord, the mobile power supply can be directly placed on the base (22), thereby avoiding the problem that when the external power supply interface is set on the support rod (21) or the back of the fan head (10), the mobile power supply has nowhere to be placed due to the insufficient length of the power cord, thereby hindering the normal implementation of the power supply method. In addition, the interface module (30) can be movable relative to the placement groove (221), so that the external power supply interface can be hidden in the placement groove (221) when not in use, thereby preventing dust and water droplets from directly contacting the external power supply interface.

[0039] Refer to the following Figure 1 and Figure 2 , the fan of the present application is described. Among them, Figure 1 This is the overall structural diagram of the fan of this application; Figure 2 This is a structural diagram of the interface module of this application.

[0040] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the fan comprises a fan head (10), a support part (20), a control part and an interface module (30), wherein the support part (20) comprises a support rod (21) and a base (22), wherein the top end of the support rod (21) is connected to the fan head (10), and the bottom end of the support rod (21) is connected to the base (22). The control part comprises a control board (not shown in the figure) and a power board (not shown in the figure), and the control board is respectively connected to a motor (not shown in the figure) and the power board for providing power to the fan blades.

[0041] The base (22) is provided with a placement groove (221), a groove (2211) is provided in the placement groove (221), one end of the interface module (30) is rotatably connected to the placement groove (221), a first external power supply interface (31) and a second external power supply interface (32) connected to a power board are provided on a side wall of the interface module (30) away from the rotation end, and a third external power supply interface (222) is also provided on the base (22).

[0042] By rotating the interface module (30), the first external power supply interface (31) and the second external power supply interface (32) can be exposed or hidden in the placement groove (221). Specifically, the fan also includes a fixing plate (33), one end of which is provided with a rotating shaft (331), and the bottom wall of the interface module (30) is provided with two parallel brackets (34), and the two ends of the rotating shaft (331) respectively pass through the two brackets (34) so ​​that the rotating shaft (331) can be rotatably connected to the bottom wall of the interface module (30). One side of the interface module (30) extends outward to form a lifting plate (35), and the interface module (30) can be rotated by pulling the lifting plate (35). When part of the interface module (30) extends above the base (22), one end of the fixing plate (33) can abut against the groove (2211), and when the interface module (30) is entirely in the placement groove (221), the two parallel brackets (34) can be received in the groove (2211). In addition, the control unit also includes a display panel (36), the control panel and the display panel (36) are both arranged on the interface module (30), and the power board is arranged on the base (22).

[0043] In this embodiment, the first external power supply interface (31) is set as a Type-A interface, the second external power supply interface (32) is set as a Type-C interface, and the third external power supply interface (222) is set as a power cord interface. It should be explained that in the prior art, the interfaces of the fan are usually set on the support rod (21) of the fan or the back of the fan head (10), and the power cord of the mobile power supply is usually short. When the interface height of the fan is too high, the mobile power supply has nowhere to be placed, thereby preventing the user from powering the fan through the mobile power supply. If a mobile power supply bracket is installed on the fan, it will affect the aesthetics of the fan. The setting of the interface module (30) allows the mobile power supply to be directly placed on the base (22) regardless of the length of the power cord when the mobile power supply is used for power supply. In addition, the setting of the interface module (30) not only improves the layout setting of multiple external power supply interfaces, but also realizes the integration of multiple external power supply interfaces and the display panel (36), so that the appearance of the fan is further simplified, and the aesthetics of the fan is improved while ensuring the normal realization of various functions of the fan, which is conducive to improving the user's experience.

[0044] It is also necessary to explain that a dedicated power conversion circuit is provided on the power board. In general, the fan is powered by the mains through the third external power supply interface (222), that is, one end of the power cord is plugged into the socket and the other end is plugged into the third external power supply interface (222). At this time, the power conversion circuit can convert 220V, 50Hz AC power into 12V DC power. In the case of a power outage or insufficient number of sockets, the fan can be powered by the solar panel through the first external power supply interface (31) or by the mobile power supply through the second external power supply interface (32). Specifically, when powered by the solar panel, the first external power supply interface (31) is used to connect the solar panel to the power board of the fan. At this time, the output voltage of the solar panel can be converted into 12V DC power through the voltage stabilizer and the power conversion circuit, wherein the voltage stabilizer is provided on the power board. When powered by the mobile power supply, the second external power supply interface (32) is used to connect the mobile power supply to the power board of the fan. At this time, the 5V DC power output by the mobile power supply can be converted into 12V DC power through the power conversion circuit.

[0045] It should be explained that, in general, the interface module (30) is entirely in the placement slot (221). When power is required through a mobile power source or a solar panel, the user can rotate the interface module (30) by pulling the lifting plate (35) upwards, and then the user can abut the bottom of the fixing plate 33 against one side of the groove (2211) in the placement slot (221), thereby completing the fixation of the interface module (30). At this time, the first external power supply interface (31) and the second external power supply interface (32) are both exposed to the outside of the placement slot (221), and then the user can power supply through the corresponding interface. When the fan stops using, the user can press the fixing plate (33) against the bottom wall of the interface module (30) and lower the interface module (30) into the placement slot (221). At this time, the two brackets (34) on the bottom wall of the interface module (30) are in the groove (2211). In addition, a display panel (36) is provided on the surface of the interface module (30), and the user can directly operate on the display panel (36) to realize the switch and gear adjustment of the fan. When the interface module (30) is rotated to the top of the base (22) and fixed, the angle between the interface module (30) and the horizontal direction is 45 degrees, and at this time, the user can clearly observe the display panel (36) in a standing state.

[0046] It is also necessary to explain that, although in this embodiment, the interface module (30) is provided with a first external power supply interface (31) to realize the power supply of the solar panel and a second external power supply interface (32) to realize the power supply of the mobile power supply, the configuration is not necessary, and those skilled in the art can change the specific configuration of the external power supply interface according to the needs. In an alternative embodiment, only the first external power supply interface (31) or the second external power supply interface (32) can be provided on the interface module (30). In another alternative embodiment, an additional interface such as a micro USB interface can be provided on the interface module (30).

[0047] In addition, although in the present embodiment, the first external power supply interface (31) and the second external power supply interface (32) are both arranged on the side wall of the interface module (30) away from the rotating end, their arrangement is not fixed. In an alternative embodiment, the first external power supply interface (31) or the second external power supply interface (32) can be arranged on any side wall on both sides of the width of the interface module (30). In another alternative embodiment, the first external power supply interface (31) or the second external power supply interface (32) can also be arranged on the bottom wall of the interface module (30). However, considering the difficulty of connecting the external power supply interface to the power cord, it is a better choice to arrange the first external power supply interface (31) and the second external power supply interface (32) on the side wall.

[0048] In addition, in this embodiment, the third external power supply interface (222) is arranged on the side wall of the base (22), but its arrangement is not fixed. In an alternative embodiment, the third external power supply interface (222) can also be arranged on the interface module (30), but considering the size of the power cord interface and the size of the interface module (30), it is a better choice to arrange the third external power supply interface (222) on the base (22). In another alternative embodiment, the third external power supply interface (222) can also be arranged on the support rod (21). In another alternative embodiment, the third external power supply interface (222) can be arranged on the surface of the base (22), but considering the dustproof and waterproof function of the external power supply interface, it is a better choice to arrange the third external power supply interface (222) on the side wall of the base (22). It should be explained that if Figure 2 As shown, a Type-A interface and a Type-C interface are also provided on one side of the third external power supply interface (222), but they are only used as a backup interface, and those skilled in the art can omit their settings as required.

[0049] It can be understood by those skilled in the art that, in the present embodiment, the two ends of the rotating shaft (331) pass through two parallel brackets (34) respectively, and the rotating shaft (331) can also slide on the two brackets (34). When the user lowers the interface module (30), the rotating shaft (331) can be placed on any side of the bracket (34), and then the fixing plate (33) is pressed against the bottom wall of the interface module (30). However, this arrangement is not necessary. In an alternative embodiment, two connecting rings can be provided only on the bottom wall of the interface module (30). In this case, the two ends of the rotating shaft (331) can be passed through the two connecting rings respectively to realize the rotatable connection between the fixing plate (33) and the interface module (30). In addition, in the present embodiment, the arrangement of the groove (2211) can realize the storage of the two brackets (34) when the interface module (30) is in the placement groove (221), but the arrangement of the groove (2211) is not necessary. In an alternative embodiment, the groove (2211) can be omitted. In this case, a groove can be opened on the bottom wall of the interface module (30), and a bracket can be arranged in the groove. The fixing plate (33) can be received in the groove on the bottom wall of the interface module (30). In this case, the fixing plate (33) can be abutted against the side wall of the placement groove (221) to fix the posture of the interface module (30). In another alternative embodiment, those skilled in the art can change the shape of the groove (2211) according to needs, or set a protrusion in the groove (2211) to adjust the fixed height of the interface module (30).

[0050] Those skilled in the art may also understand that, in this embodiment, extending one side of the interface module (30) outward to form a lifting plate (35) is conducive to quickly rotating the interface module (30) above the base so that the first external power supply interface (31) and the second external power supply interface (32) are exposed to the outside, but its provision is not necessary. In an alternative embodiment, the lifting plate (35) may be omitted. In another alternative embodiment, those skilled in the art may change the setting position and shape of the lifting plate (35) as required, as long as it does not affect the realization of its normal function, for example, a lifting ring may be provided above the interface module (30).

[0051] Those skilled in the art may also understand that, although in this embodiment, the external power supply interface is exposed or hidden in the placement slot (221) by rotating the interface module (30) and the placement slot (221), its setting is not fixed, and those skilled in the art may change it as needed, as long as it does not affect the normal function of the interface module (30). For example, the interface module (30) may be moved vertically relative to the placement slot (221) by a lifting mechanism. In addition, the setting of the display panel (36), the control panel, the power board, etc. is not fixed, and those skilled in the art may change it as needed. In an alternative embodiment, the display panel (36) may be set on the support rod (21), but considering the aesthetics of the fan and the degree of functional integration, setting the display panel (36) on the interface module (30) is a better choice.

[0052] In addition, although in this embodiment, the angle between the interface module (30) and the horizontal direction is 45°, which is conducive to the user to clearly observe the display panel (36), the setting of the angle is not fixed. Those skilled in the art can change the angle between the interface module (30) and the horizontal direction according to needs, for example, setting the angle to any value between 30° and 60°. However, it has been verified through experiments that when the angle is set to 45°, the user has a better observation effect on the display panel (36), so setting the angle to 45° is a better choice.

[0053] Those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present application and form different embodiments. For example, in the claims of the present application, any one of the claimed embodiments may be used in any combination.

[0054] So far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present application.
