For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] This invention aims to provide a fan with adjustable airflow and a fixed placement capability. This allows users to fix the handheld fan in place outdoors and adjust the fan's outlet direction, improving the ease of use.

[0025] As shown in Figures 1 to 12, this embodiment of the utility model provides a handheld fan, such as... Figure 1-2 As shown, the handheld fan includes a handle 1 and a rotating shell 2 rotatably connected to the top of the handle 1. The rotating shell 2 is fixedly connected to the fan body 3. In this embodiment, the handle 1 is formed by fastening a first handle 16 and a second handle 17 together. The handle 1 has an internal structure with a receiving space in which a power supply 5 is installed. The power supply 5 is used to supply power to the motor 51 to ensure the operation of the fan.

[0026] like Figure 1-5 The outer side of the handle 1 is provided with a fixing end 8 for fixing the strap 4, so that the strap 4 can be fixed to the handle 1. Specifically, the outer side of the handle 1 has a pair of recesses 11, the horizontal plane of which is lower than the horizontal plane of the outer handle 1, so that after the strap 4 is fixed in the recesses 11, the outer surface of the strap 4 is basically horizontal with the horizontal plane of the outer handle 1 of the recesses 11, improving the user's grip comfort. The fixing end 8 of the handle 1 is a positioning post 81 extending horizontally outward on the recesses 11. Preferably, the positioning post 81 is cylindrical, and the top area of ​​the positioning post 81 extends horizontally outward, so that the diameter of the top of the positioning post 81 is larger than the diameter of the bottom of the positioning post 81.

[0027] The strap 4 is fixed to the outside of the handle 1 via the fixed end 8. The strap 4 is elastic and can undergo elastic deformation when it encounters external force. Specifically, the strap 4 has a connecting hole 41, the diameter of which is approximately the same as the diameter of the bottom of the positioning post 81.

[0028] In use, the connecting holes 41 on both sides of the strap 4 are fitted onto the bottom area of ​​the positioning post 81, so that the strap 4 is detachably fixed to the positioning post 81. If it is necessary to fix the fan to an external object (the handle of an umbrella), simply remove the connecting hole 41 on one side of the strap 4 from the positioning post 81, then wrap the strap 4 around the handle, and finally fix the removed connecting hole 41 back to the positioning post 81. The tension of the strap 4 fixes the handheld fan to the umbrella. The user does not need to hold the handheld fan separately when using an umbrella or in other usage scenarios, making it more convenient to use.

[0029] like Figure 10-12In another embodiment of this utility model, the fixed end 8 of the handle 1 consists of through holes 82 on both sides of the handle 1 for the strap 4 to pass through. One end of the strap 4 has a fixing part 42, which is cylindrical and integrally connected with the strap 4. The strap 4 has a connecting hole 41, the size of which is smaller than the size of the fixing part 42. This prevents the fixing part 42 from detaching from the connecting hole 41 after it is inserted into the connecting hole 41, and also allows the strap 4 to be detachably connected to the handle 1. In use, the strap 4 is passed through the through holes 82 in sequence and wrapped around the back of the object to be fixed (e.g., the handle of an umbrella). The fixing part 42 is then inserted into the connecting hole 41, so that the fan is fixed to the external object by the tension of the strap 4. The strap 4 is made of an elastic material, and multiple connecting holes 41 are provided on the strap 4, so that the fixed length of the strap 4 can be changed to match external objects of various sizes.

[0030] By setting the strap 4 on the outside of the handle 1, the user can fix the handheld fan to an external object, so that the user does not have to fix the fan by hand, thus improving the user experience.

[0031] like Figure 3-4 The handle 1 has a accommodating area 13 above it for the rotating shell 2 to rotate. The top of the handle 1, which is also the two sides of the accommodating area 13, has shaft holes 14. Specifically, the rotating shell 2 has a rotating shaft 21 on both sides that is placed in the shaft holes 14, so that the rotating shell 2 can rotate relative to the top of the handle 1 through the rotating shaft 21.

[0032] In a preferred embodiment of this utility model, the rotating shell 2 is formed by fastening together a first rotating shell 22 and a second rotating shell 23. A rectangular through-hole is provided on the outer side of the first rotating shell 22, and a digital display screen 6 electrically connected to the PCB board is placed in the through-hole. The second rotating shell 23 is fixedly connected to the fan body 3, specifically, the second rotating shell 23 is fixedly connected to the outer shell 31 in the fan body 3, so that the rotating shell 2 and the fan body 3 are fixedly connected and rotate as a whole. The fan body 3 achieves relative rotation at the top of the handle 1 through the rotating shaft 21 on the rotating shell 2.

[0033] like Figure 6-9The rotating housing 2 has a reserved space inside for accommodating a PCB board. The PCB board is fixed to the inside of the rotating housing 2 with bolts. A through-hole 26 is provided on the inner side of the rotating shaft 21 on at least one side of the rotating housing 2. The electronic switch on the PCB board is directly opposite the first through-hole 26. A second through-hole 18 is provided on the outer side of the shaft hole 14 corresponding to the first through-hole 26. The first through-hole 26, the second through-hole 18, and the shaft hole 14 correspond to each other. A button slot 15 for placing the locking part 72 is provided between the shaft hole 14 and the second through-hole 18. Specifically, a button 7 is embedded in the accommodating space inside the first through hole 26 and the second through hole 18. The button 7 consists of a contact part 71, a locking part 72, and a pressing part 73. During installation, the contact part 71 is located in the first through hole 26 and abuts against the electronic switch point. The pressing part 73 is located in the second through hole 18. The locking part 72 is located in the button slot 15 between the shaft hole 14 and the second through hole 18. The size of the locking part 72 is larger than the diameter of the first through hole 26 and the second through hole 18 to prevent the button 7 from falling out of the first through hole 26 and the second through hole 18. The outer end face of the pressing part 73 protrudes from the outside of the second through hole 18, making it convenient for the user to press the button 7. In use, the user presses the pressing part 73 of the button 7, which drives the contact part 71 on the button 7 to trigger the electronic switch, thereby controlling the fan's on / off state.

[0034] Most existing designs place the button 7 on the handle 1 or the digital display 6 on the rotating shell 2. When the handheld fan is folded, placed on a table, or fixed to an external object, the folded fan body 3, the table, or the external object will obstruct the button 7. This means that the user needs to swing the fan body 3 again or pick up the handheld fan to press the button 7, which is inconvenient. In contrast, this patent places the button 7 on the side of the pivot 21. The rotatable fan body 3, the table, or external objects will not obstruct the button 7, allowing the user to operate it directly. In addition, the button 7 of this patent has a compact structure, making installation easier and eliminating the need for extra wiring.

[0035] like Figure 6 and Figure 8-9 In this invention, the fan body 3 includes an outer shell 31 located above the rotating shell 2, an inner shell 32 fixed inside the outer shell 31, and electronic components such as fan blades 53 and a motor 51. All electronic components are electrically connected, enabling the fan to operate normally. Specifically, the second rotating shell 23 is integrally formed with the outer shell 31, and rotating the outer shell 31 drives the relative rotation of the rotating shell 2 on the handle 1. The outer shell 31 has a cylindrical structure, with an open front and a mesh cover on the back. The specific structure of the fan body 3 is not the focus of this invention and will not be described further here.

[0036] The description of various embodiments of this utility model is for illustrative purposes only and is not intended to limit the scope of the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used in the embodiments is intended to best explain the principles of the embodiments, their practical application, or to enable others skilled in the art to understand the disclosed embodiments, and should not be construed as limiting the utility model.
