Modes for Carrying Out the Invention

[0016] Hereinafter, with reference to the drawings in the embodiments of the present invention, the technical means in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative labor shall fall within the protection scope of the present invention.

[0017] As shown in FIGS. 1 to 8, the side-cooling type cooling fan includes a fan head 1 and a grip handle 2. The grip handle 2 is surrounded in the circumferential direction by a first side surface, a second side surface, a third side surface, and a fourth side surface. The first side surface is provided on the air blowing direction side of the fan head 1. The third side surface is provided opposite to the first side surface. The second side surface and the fourth side surface are provided on both the left and right sides of the first side surface, respectively. A conductive plate 4 is provided on the outer surface of the grip handle 2. The conductive plate 4 is provided on the upper The grip handle 2 is provided with an extending longitudinal direction thereof, and a receiving cavity is formed inside the grip handle 2, and a cold-heat generating device is mounted in the receiving cavity. The grip handle 2 is provided with an intake port 23 and an exhaust port 24, and the cooling end of the cold-heat generating device is connected to the conductive plate 4 in a heat-conductive manner, and the heat-dissipating end of the cold-heat generating device is provided in communication with the exhaust port 24, and heat is dissipated to the outside through the exhaust port 24, and the exhaust port 24 is provided on the second side surface and / or the fourth side surface, and the exhaust port 24 is provided on the second side surface and / or the fourth side surface. If the air outlets 24 are provided on these two sides, it will help to prevent the hot air blown out from the air outlets 24 from acting on the human body and causing an unpleasant tactile sensation, and it will also help to prevent the heat-dissipating airflow carrying the heat from returning into the operating airflow of the fan head 1, thereby reducing the normal operating effect of the fan head 1. The grip handle 2 is divided into five equal segments in the longitudinal direction from the end closest to the fan head 1 to the end remote from the fan head 1, and the air outlets 24 are provided at the end of the grip handle 2 closest to the fan head 1, and are provided within the area where the first segment and / or the second segment are located. By limiting the air outlet 24 to between the first and second segments at the upper end of the grip handle 2, it is ensured that there is a length left at the lower end of the grip handle 2 for a human hand to grasp, and it is possible to avoid the phenomenon that the remaining length of the grip handle 2 is too short and blocks the air outlet 24 during the process of gripping, which will affect the heat dissipation effect of the cooling device.

[0018] The connection method between the cold generating device and the grip handle 2 has two specific embodiments in this application.

[0019] In Example 1, as shown in FIGS. 1 to 4, the intake port 23 is provided on the second side surface and / or the fourth side surface and is provided adjacent to the exhaust port 24. The heat and cold generation device includes a wind guide cover 31, a blower blade group 32, a radiator 33, and a semiconductor cooling plate 34. The wind guide cover 31 is provided with a first ventilation hole 311, and the first ventilation hole 311 is provided in communication with the intake port 23. The blower blade group 32 is mounted in the wind guide cover 31. The radiator 33 is provided on the side away from the first ventilation hole 311 of the blower blade group 32. The radiator 33 is provided with a second ventilation hole 331, and the second ventilation hole 331 is provided in communication with the exhaust port 24. The heat generating end of the semiconductor cooling plate 34 is thermally conductively connected to the radiator 33, and the cooling end of the semiconductor cooling plate 34 is thermally conductively connected to the conduction plate 4. When the semiconductor cooling plate 34 operates, the cooling end cools the conduction plate 4 in a heat conduction manner, so that the conduction plate 4 achieves a cooling effect. In this case, based on the principle of energy equivalent exchange, the heat generating end of the semiconductor cooling plate 34 generates heat. After the heat quantity is conducted to the radiator 33, it is simultaneously diffused on the radiator 33. Finally, when the air flow formed by the blower blade group 32 flows through the radiator 33, the heat quantity on the radiator 33 is discharged from the exhaust port 24 to the outside of the housing of the gripping handle 2, thereby achieving the effect of heat dissipation.

[0020] In Example 2, as shown in FIGS. 5 to 8, the intake port 23 is provided on the third side surface. The cooling and heating device includes a semiconductor cooling plate 34, a radiator 33, and a blower blade group 32. The cooling end of the semiconductor cooling plate 34 is thermally conductively connected to the conduction plate 4, and the heat generating end of the semiconductor cooling plate 34 is thermally conductively connected to the radiator 33. A blower blade group 32 is provided on the side of the radiator 33 opposite to the semiconductor cooling plate 34. The radiator 33 is provided with a second ventilation hole 331. The second ventilation hole 331 is provided in communication with the exhaust port 24. The blower blade group 32 guides the air at the intake port 23 to blow out to the outside from the exhaust port 24 after flowing through the radiator 33 and the second ventilation hole 331. The semiconductor cooling plate 34 is surrounded by a separation frame 341 in the circumferential direction. The separation frame 341 serves to assist in fixing the semiconductor cooling plate 34 and achieves a heat insulation effect, so that the semiconductor cooling plate 34 and the conduction plate 4 do not interfere with each other. A housing cavity cover 29 is attached to the opening of the housing cavity, and the intake port 23 is provided on the housing cavity cover 29.

[0021] The blower head 1 and the grip handle 2 are rotatably connected by a rotation mechanism. The rotation mechanism includes a rotation shaft 51 integrally connected to the blower head 1, a shaft seat 52 provided on the grip handle 2, and a damping ring 53 interposed between the rotation shaft 51 and the shaft seat 52. The rotation shaft 51 is inserted into the shaft seat 52 and rotatably connected to the shaft seat 52.

[0022] The above-mentioned gripping handle 2 includes a handle front housing 21 and a handle rear housing 22 that are connectable to engage with each other. A circuit board assembly 25 and a storage battery 26 are provided between the handle front housing 21 and the handle rear housing 22. The storage battery 26 is electrically connected to the circuit board assembly 25. A control button 27 and a USB interface 28 are electrically connected and provided on the circuit board assembly 25. Both the control button 27 and the USB interface 28 are provided in a through hole provided in advance in the housing of the gripping handle and extend outward from the through hole. The control button 27 adjusts and switches the operating states and operating modes of the blower blade group 32 and the semiconductor cooling plate 34. The USB interface can charge the storage battery 26 when connected to an external power supply using a charging cable.

[0023] As described above, in the present invention, a conductive plate 4 is provided on the outer surface of the gripping handle 2 of the portable fan. The conductive plate 4 achieves a cooling effect by the action of the heat and cold generating device. In the process of the consumer gripping and using the portable fan, the consumer will not feel hot, and the cooling feeling of the fan can be improved by cooling the palm.
