Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically a small fan. Background Technology

[0002] To improve the portability of fans, existing technology provides a small fan including a base, a handle on the base, a battery inside the handle, a small fan electrically connected to the battery, and a cover on the outside of the small fan. The small fan can be controlled by a switch button on the handle. For example, the small fan disclosed in Chinese Patent Publication No. CN214424728U and Chinese Patent Publication No. CN208417008U are relatively portable. However, in actual use, the air vents on the cover are large and directly face the fan blades. Long hair and other foreign objects can easily get caught in the cover and entangle the fan blades, causing the small fan to become stuck. This not only shortens the lifespan of the small fan but also poses a significant safety hazard. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned shortcomings by providing a small fan that can stagger the air outlet and fan blades, thus preventing long hair and other foreign objects from easily getting caught in the casing and tangling around the fan blades, causing the small fan to become entangled and jammed. This extends the service life of the small fan and makes it safer and more reliable to use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A small fan includes a housing, a control button located on the top of the housing, a vertically arranged mounting cavity and a flow channel inside the housing, a controller and a battery disposed in the mounting cavity, an air outlet connected to the flow channel on the side of the housing, a fan disposed in the flow channel, and an air inlet connected to the flow channel on the bottom of the housing. The air inlet of the fan faces downward and the air outlet faces upward. The control button, the battery and the fan are all electrically connected to the controller.

[0006] Furthermore, the air outlet is provided with multiple diverter vanes at equal intervals.

[0007] Furthermore, the air outlet extends from near the top of the housing to the middle of the housing.

[0008] Furthermore, the outer shell includes a middle shell, a top shell, and a bottom shell, and the middle shell and the top shell, as well as the middle shell and the bottom shell, are connected by screws.

[0009] Furthermore, the air inlet is located on the top shell, and a mounting port extending to the middle of the middle shell is provided on one side of the top of the middle shell. A connecting block for snapping onto the mounting port is provided at the bottom of the top shell, and the air outlet is located on the connecting block.

[0010] Furthermore, the air inlet is disposed on the bottom shell, and the air inlet extends from the bottom of the bottom shell to the side of the bottom shell.

[0011] Furthermore, a charging interface is provided on the side of the housing away from the air outlet, and the charging interface is used to charge the battery.

[0012] The beneficial effects of this utility model are:

[0013] In practical applications, by setting an air outlet on the side of the vertically arranged flow channel and an air inlet at the bottom, the fan blades are staggered from the air outlet, preventing long hair and other foreign objects from easily getting caught inside the casing. This invention can stagger the air outlet and the fan blades, preventing long hair and other foreign objects from easily getting caught in the casing and tangling around the fan blades, thus preventing the small fan from getting stuck and extending its service life, making it safer and more reliable to use.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a small fan includes a housing 1, a control button 2 located on the top of the housing 1, a vertically arranged mounting cavity 11 and a flow channel 12 inside the housing 1, a controller 3 and a battery 4 disposed in the mounting cavity 11, an air outlet 13 connected to the flow channel 12 disposed on the side of the housing 1, a fan 5 disposed in the flow channel 12, and an air inlet 14 connected to the flow channel 12 disposed at the bottom of the housing 1. The air inlet end of the fan 5 faces downward and the air outlet end faces upward. The control button 2, the battery 4 and the fan 5 are all electrically connected to the controller 3.

[0020] This application can be used handheld or placed on a table. By setting an air outlet 13 on the side of the vertically arranged flow channel 12 and an air inlet 14 at the bottom, the blades of the fan 5 are staggered from the air outlet 13, which avoids the situation where long hair and other foreign objects can easily be rolled into the inside of the outer casing 1. The power range of the fan 5 is 9 to 12W. This utility model can stagger the air outlet and the fan blades of the fan 5, which can prevent long hair and other foreign objects from being easily rolled into the casing and tangled in the fan blades of the fan 5, thus extending the service life of the small fan and making it safer and more reliable to use.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the air outlet 13 is provided with multiple diverter plates 6 at equal intervals; in this embodiment, the air outlet is divided by the diverter plates 6, making the air outlet more uniform and comfortable.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the air outlet 13 extends from near the top of the outer casing 1 to the middle of the outer casing 1; in this embodiment, when the air outlet 13 extends from near the top of the outer casing 1 to the middle of the outer casing 1, the air outlet area is larger.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the outer shell 1 includes a middle shell 101, a top shell 102, and a bottom shell 103. The middle shell 101 and the top shell 102, and the middle shell 101 and the bottom shell 103 are all connected by screws. In this embodiment, the middle shell 101, the top shell 102, and the bottom shell 103 are injection molded, and then the middle shell 101 and the top shell 102, and the middle shell 101 and the bottom shell 103 are connected by screws, which simplifies the manufacturing process of the outer shell 1 and reduces the production cost.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the air inlet 14 is disposed on the top shell 102, and the top side of the middle shell 101 is provided with a mounting port 1011 extending to the middle of the middle shell 101. The bottom of the top shell 102 is provided with a connecting block 1021 that engages with the mounting port 1011, and the air outlet 13 is disposed on the connecting block 1021. In this embodiment, by disposing of the connecting block 1021 on the top shell 102, the demolding difficulty of the injection-molded horizontal flow divider 6 of the middle shell 101 is reduced.

[0025] like Figure 1 , Figure 2 , Figure 3and Figure 4 As shown, the air inlet 14 is disposed on the bottom shell 103, and the air inlet 14 extends from the bottom of the bottom shell 103 to the side of the bottom shell 103. In this embodiment, when the air inlet 14 extends from the bottom of the bottom shell 103 to the side of the bottom shell 103, it is placed on a table for use, and the air inlet 14 is more likely to draw air from the side.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a charging interface is provided on the side of the outer casing 1 away from the air outlet 13. The charging interface is used to charge the battery 4. In this embodiment, the battery 4 is charged through the charging interface.

[0027] The specific embodiments described herein are merely illustrative examples of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the scope defined by this utility model.
