[0004] Market demand.

[0005] A handheld fan is a small fan with a handle attached to the main body. It can be carried around by holding the handle, and its portability makes it popular among consumers.

[0006] However, after prolonged use of handheld fans, consumers often experience stuffy and sweaty palms. This unpleasant sensation not only affects the user experience but also reduces the fan's cooling effect. This is because the palms are highly sensitive to temperature, and the information perceived is amplified by the brain, influencing the body's perception. If the palms feel stuffy, the subconscious mind tends to perceive a hot environment; conversely, if the palms feel cool, the subconscious mind tends to perceive a cool environment. Therefore, improving the unpleasant sensation caused by prolonged use of handheld fans is crucial for enhancing their effectiveness. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-8 A side-cooled cooling fan includes a fan head 1 and a handle 2. The handle 2 is circumferentially formed by a first side, a second side, a third side, and a fourth side. The first side is located on the side of the fan head 1 facing the air outlet, the third side faces the first side, and the second and fourth sides are located on the left and right sides of the first side, respectively. A conductive plate 4 is laid on the outer surface of the handle 2, extending along the length of the handle 2. A cavity is provided inside the handle 2, and a cooling / heating generator is installed in the cavity. An air inlet 23 and an air outlet 24 are provided on the handle 2. The cooling end of the cooling / heating generator is thermally connected to the conductive plate 4, and the heat dissipation end of the cooling / heating generator is connected to the air outlet 24, through which heat is dissipated outward. The air outlet 24 is located on the second side. When the air outlet 24 is located on the first and / or fourth side, it can prevent the warm air blown out from the air outlet 24 from acting on the human body and causing an unpleasant tactile sensation. It also helps to prevent the heat dissipation airflow carrying heat from flowing back into the working airflow of the fan head 1, thereby reducing the normal working effect of the fan head 1. The handle 2 is divided into five segments along its length from the end closest to the fan head 1 to the end furthest from the fan head 1. The air outlet 24 is located at the end of the handle 2 closest to the fan head 1 and is located in the area of ​​the first and / or second segment. By restricting the air outlet 24 to the area between the first and second segments at the upper end of the handle 2, it can ensure that the lower end of the handle 2 has sufficient length for the person to hold and grip. This avoids the phenomenon of the air outlet 24 being blocked during the person's holding process due to the short grip length of the handle 2, which would affect the heat dissipation effect of the heat generation device.

[0028] The combination of the heating / cooling device and the handheld handle 2 has two specific embodiments in this application:

[0029] Example 1, see Figures 1-4 The air inlet 23 is disposed on the second side and / or the fourth side, and the air inlet 23 is disposed adjacent to the air outlet 24. The heat generation device includes an air guide shroud 31, a fan blade assembly 32, a radiator 33, and a semiconductor cooling chip 34. The air guide shroud 31 is provided with a first ventilation hole 311, which is connected to the air inlet 23. The fan blade assembly 32 is installed inside the air guide shroud 31. The radiator 33 is disposed on the side of the fan blade assembly 32 away from the first ventilation hole 311. The radiator 33 is provided with a second ventilation hole 331, which is connected to the air outlet 24. The heating end of the semiconductor cooling chip 34 is thermally connected to the radiator 33, and the cooling end of the semiconductor cooling chip 34 is thermally connected to the conductive plate 4. When the semiconductor cooling chip 34 is working, the cooling end cools the conductive plate 4 through heat conduction, thereby achieving a cooling effect. At this time, according to the principle of equal energy exchange, the heating end of the semiconductor cooling chip 34 will generate heat. The heat is conducted to the heat sink 33 and diffuses on the heat sink 33. Finally, the airflow formed by the fan blade assembly 32 carries the heat on the heat sink 33 out of the handle 2 housing from the air outlet 24, thereby achieving a heat dissipation effect.

[0030] Example 2, see Figures 5-8 The air inlet 23 is located on the third side. The heating and cooling device includes a semiconductor cooling chip 34, a heat sink 33, and a fan blade assembly 32. The cooling end of the semiconductor cooling chip 34 is thermally connected to the conductive plate 4, and the heating end of the semiconductor cooling chip 34 is thermally connected to the heat sink 33. The fan blade assembly 32 is located on the side of the heat sink 33 facing away from the semiconductor cooling chip 34. A second ventilation hole 331 is provided on the heat sink 33. The second ventilation hole 331 is connected to the air outlet 24. The fan blade assembly 32 guides the air located at the air inlet 23 to flow through the heat sink 33 and the second ventilation hole 331 and then blows it outward from the air outlet 24. The semiconductor cooling chip 34 is surrounded by an isolation frame 341. The isolation frame 341 serves to help fix the semiconductor cooling chip 34 and also has a heat insulation effect, so that the semiconductor cooling chip 34 and the conductive sheet 4 do not interfere with each other. The cavity opening is covered with a cavity cover plate 29, and the air inlet 23 is disposed on the cavity cover plate 29.

[0031] The fan head 1 and the hand handle 2 are rotatably connected by a rotating mechanism. The rotating mechanism includes a rotating shaft 51 integrally connected to the fan head 1, a bearing seat 52 disposed on the hand handle 2, and a damping ring 53 sandwiched between the rotating shaft 51 and the bearing seat 52. The rotating shaft 51 is inserted into the bearing seat 52 and is rotatably connected to the bearing seat 52.

[0032] The handheld handle 2 includes a front handle shell 21 and a rear handle shell 22 that are connected to each other. A circuit board assembly 25 and a battery 26 are disposed between the front handle shell 21 and the rear handle shell 22. The battery 26 is electrically connected to the circuit board assembly 25. The circuit board assembly 25 is electrically connected to a control button 27 and a USB interface 28. Both the control button 27 and the USB interface 28 are disposed in a pre-set through hole in the handheld handle shell and extend outward from the through hole. The control button 27 is used to adjust and switch the working state and working mode of the fan blade assembly 32 and the semiconductor cooling chip 34. When the USB interface is connected to an external power supply via a charging cable, it can charge the battery 26.

[0033] In summary, this utility model provides a conductive plate 4 on the outer surface of the handle 2 of the handheld fan. The conductive plate 4 achieves a cooling effect after being activated by the heat-generating device. When consumers hold and use the handheld fan, they will not feel stuffy; on the contrary, the cooling effect of the fan can be enhanced by cooling the palm of their hand.
