Description

Technical Field

[0001] This utility model relates to the field of fans, and in particular to handheld fans. Background Technology

[0002] Traditional fans drive airflow by rotating fan blades, simulating self-heating air to lower perceived temperature. However, traditional fans have limited cooling effects and cannot improve air humidity. Therefore, air-conditioned fans that utilize water evaporation to remove heat and have humidification functions were developed. But existing air-conditioned fans suffer from complex structures, single cooling water circuits, poor cooling performance, low energy efficiency, and inconvenient airflow adjustment. Therefore, handheld fans have been proposed. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0004] A handheld fan includes a base and a front shell vertically positioned on one side of the base. It also includes a support base for supporting the fan body, which consists of the base and front shell. A motor is positioned between the front and base shells, with the motor laterally located on one side of the front shell. The motor's drive end is connected to fan blades, which are vertically positioned between the front and base shells. An air inlet shroud is vertically positioned on the back of the base shell, and the motor drives the fan blades to rotate between the air inlet shroud and the back of the front shell. An air outlet shroud is vertically positioned on the front side of the front shell, and a cooling element is positioned between the air outlet shroud and the front shell. The cooling element is fixed to the other side of the front shell, and a cooling fin is electrically connected to the front side of the cooling element.

[0005] Preferably, a heat-conducting element is vertically arranged on the front side of the air outlet hood, and the heat-conducting element is electrically connected to the cooling element.

[0006] Preferably, a circuit board is provided between the front shell and the bottom shell, and a battery is provided on one side of the circuit board. The circuit board and the battery are electrically connected. The circuit board is electrically connected to the motor, the cooling chip and the cooling conductor, and the battery is electrically connected to the motor, the cooling chip and the cooling conductor.

[0007] Preferably, the circuit board is also electrically connected to a button, which is located on the side outside the casing, and the button is electrically connected to the motor.

[0008] Preferably, a power switch is provided on the side away from the button, and the power switch is located on the other side of the outer shell, and the power switch is electrically connected to the battery and the circuit board respectively.

[0009] Preferably, the front side of the housing is also provided with a display screen, and the display screen is electrically connected to the circuit board, and a display screen lens is vertically attached to the front side of the display screen to protect it.

[0010] Preferably, a bearing is provided at the connection between the motor and the fan blade, and the connecting end of the fan blade is inserted into the bearing, while the other end of the bearing is located inside the motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When the user holds the fan and starts the motor, the motor drives the fan blades to rotate, and at the same time, it draws in the external airflow. The drawn airflow passes through the air intake cover and is guided to flow under the continuous rotation of the fan blades. The guided airflow flows out from the faceplate and is then cooled by driving the cooling plate. The cooling plate diffuses the generated cold air through the cooling guide, so that when the airflow flows out from the faceplate and gradually passes through the cooling guide and the air outlet cover, the airflow continuously interacts with the cold air diffused from the cooling guide and is cooled down. Thus, the cold airflow allows the user to hold the fan to cool down the surface temperature in hot outdoor weather.

[0017] 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.

[0018] Please see Figure 1-2 In this embodiment of the utility model, the handheld fan includes a bottom shell 2 and a front shell 1 vertically disposed on one side of the bottom shell 2, and is also equipped with a support base 5 for supporting and placing the fan body composed of the bottom shell 2 and the front shell 1. A motor 9 is disposed between the front shell 1 and the bottom shell 2, and the motor 9 is horizontally located on one side of the front shell 1. The drive end of the motor 9 is connected to a fan blade 10, and the fan blade 10 is vertically located between the front shell 1 and the bottom shell 2. An air inlet shroud 11 is vertically disposed on the back of the bottom shell 2, and the motor 9 drives the fan blade 10 to rotate between the air inlet shroud 11. An air outlet shroud 3 is vertically disposed on the front side of the front shell 1, and a cooling guide 6 is disposed between the air outlet shroud 3 and the front shell 1. The cooling guide 6 is fixed to the other side of the front shell 1. The cooling element 6 is electrically connected to the cooling plate 7 on its front side. When the user holds the fan and starts the motor 9, the motor 9 drives the fan blades 10 to rotate. While rotating, the fan blades 10 draw in external airflow. The drawn airflow passes through the air intake shroud 11 and is guided to flow under the continuous rotation of the fan blades 10. The guided airflow flows out of the faceplate 1 and then drives the cooling plate 7 to cool it. The cooling plate 7 diffuses the generated cold air through the cooling element 6. As the airflow flows out of the faceplate 1 and gradually passes through the cooling element 6 and the air outlet shroud 3, the airflow continuously interacts with the cold air diffused by the cooling element 6 and cools down. This results in the cold airflow flowing out, allowing the user to cool the surface temperature of the skin by holding the fan in hot outdoor weather.

[0019] The air outlet hood 3 has a heat-conducting component 4 vertically arranged on its front side, and the heat-conducting component 4 is electrically connected to the cooling chip 7, so that the heat generated by the cooling chip 7 when it is working can be directed through the heat-conducting component 4.

[0020] A circuit board 12 is also provided between the front shell 1 and the bottom shell 2, and a battery 14 is provided on one side of the circuit board 12.

The circuit board 12 is electrically connected to the motor 9, the cooling chip 7 and the cooling conductor 6 respectively, and the battery 14 is electrically connected to the motor 9, the cooling chip 7 and the cooling conductor 6 respectively. Thus, the battery 14 provides power to the motor 9, the cooling chip 7, the circuit board 12 and the cooling conductor 6 so that the fan can be used normally.

[0021] The circuit board 12 is also electrically connected to a button 15, which is located on the side outside the casing 1. The button 15 is electrically connected to the motor 9, so that pressing the button 15 drives the motor 9 to rotate, thereby driving the fan blade 10 to rotate.

[0022] A power switch 13 is provided on the side away from the button 5, and the power switch 13 is located on the other side outside the faceplate 1. The power switch 13 is electrically connected to the battery 14 and the circuit board 12 respectively, so that the battery 14 can supply power to the circuit board 12 and other electronic devices by pressing the power switch 13.

[0023] The front side of the faceplate 1 is also provided with a display screen (not shown in the figure), and the display screen is electrically connected to the circuit board 12. The display screen lens 16 is vertically attached to the front side of the display screen to protect it, so that the speed level of the motor 9 can be displayed through the display screen.

[0024] A bearing 8 is provided at the connection between the motor 9 and the fan blade 10, and the connecting end of the fan blade 10 is inserted into the bearing 8, while the other end of the bearing 8 is located inside the motor 9.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
