Description

Technical Field

[0001] This invention belongs to the field of fan technology, and more specifically, relates particularly to a fan with a handheld camera.

Background Art

[0002] A handheld fan is a small electric air blower with a lightweight design that is easy to hold and operate with one hand. Generally, it uses a built-in rechargeable battery as a power source, and a motor drives the fan blades to rotate to generate a directional airflow. This device is mainly utilized in scenes such as outdoor activities, commuting, indoor movement, or local spaces, providing immediate and directional air blowing to users, aiming to relieve heat, promote sweat evaporation, and lower the perceived temperature. It is a portable personal air blower device different from urban, fixed fans.

[0003] Conventional handheld fan products generally have the problem of a single function. Their main and even only function is limited to providing local air blowing. Such single functionality greatly restricts its application scenarios, making it difficult for users to enjoy the convenience of portable air blowing while satisfying the growing daily needs for multifunctional integrated devices. For example, when users are engaged in outdoor activities or traveling, they often need to record videos (such as taking photos and videos) simultaneously. However, conventional handheld fans cannot provide such auxiliary functions, and users need to carry a dedicated imaging device separately, which not only increases the carrying burden but also reduces convenience, and is particularly inconvenient in scenarios of one-handed operation. Therefore, in order to maintain the core function of portable air blowing and expand its application range to improve the user experience, the development of a new handheld device that can effectively integrate the video collection function has become an urgent task.

[0019] (Examples) As shown in Figures 1 to 3, This invention provides a fan with a handheld camera, which includes a handheld body 1 to which a connecting arm 3 is rotatably connected at the top, a fan assembly including a mounting cylinder connected to the other end of the connecting arm 3, fan blades 5 mounted inside the mounting cylinder, and a camera 8 mounted near the center of the intake port of the mounting cylinder. By integrating the camera 8 at the center of the intake port of the mounting cylinder of the fan assembly, obstruction of the camera 8 by the rotation of the fan blades 5 can be avoided to the greatest extent possible, a clear and unobstructed field of view can be obtained, and auxiliary heat dissipation for the camera 8 can be performed by the airflow from the intake port, improving the stability of its operation.

[0020] Here, the mounting cylinder includes an outer cylinder 2 in which an inner cylinder 4 is fixedly mounted. A mounting bracket is installed at one end of the inner cylinder 4 near the air outlet, and a motor, which is scalably connected to the fan blades 5, is fixedly mounted at the inner center of the mounting bracket. By adopting a two-layer structure design in which the inner cylinder 4 is enclosed by the outer cylinder 2, the rigidity of the entire structure is strengthened, effectively reducing the transmission of noise and vibration to the outside due to the high-speed rotation of the motor and fan blades 5, and improving user comfort. By providing a stable support platform for the motor with the mounting bracket at the end of the inner cylinder 4, stable operation of the motor is ensured, resulting in high rotational concentricity of the fan blades 5 and superior airflow efficiency.

[0021] Here, a digital display tube 9 for displaying fan speed stage information is mounted on the outer center of the mounting bracket, and a hemispherical protective cover 10 is fitted over the outer part of the mounting bracket closest to the digital display tube 9. The digital display tube 9 is positioned at the outer center of the mounting bracket, making its location conspicuous and allowing users to intuitively and clearly confirm the current fan operating speed stage information. The hemispherical protective cover 10 covers the outside of the digital display tube 9, effectively protecting it from erosion by dust and water vapor and damage from accidental impacts, while its transparent or translucent material ensures that the display content is clearly visible, improving the durability and reliability of the equipment.

[0022] Here, at both ends of the outer cylinder body 2, a rear fixing ring 7 and a front fixing ring 11 for positioning and fixing the inner cylinder body 4 are respectively attached. At one end of each of the rear fixing ring 7 and the front fixing ring 11, a plurality of sets of connecting claws are installed. At both ends of the inner cylinder body 4, locking blocks connected to the connecting claws corresponding to the connecting claws are installed. The rear fixing ring 7 and the front fixing ring 11 are fitted and connected to the locking blocks at both ends of the inner cylinder body 4 through the plurality of sets of connecting claws on them, realizing accurate positioning and firm fixing of the inner cylinder body 4 inside the outer cylinder body 2. By the engaging connection method, the assembly and disassembly of the fan assembly become more convenient and efficient, facilitating production manufacturing and later maintenance.

[0023] Here, a fixing frame is installed at the center of the rear fixing ring 7. The camera 8 is fixedly attached to the outer center of the fixing frame. A protective net 6 is attached between the rear fixing ring 7 and the inner cylinder body 4. The fixing frame specially installed at the center of the rear fixing ring 7 provides a reliable and accurate mounting base for the camera 8, ensuring that the camera 8 maintains stability during the operation of the device, reducing the impact of vibration on the imaging quality. The protective net 6 can effectively prevent a user's finger, hair or other foreign objects from being卷入 into the fan blade rotating at high speed from the air inlet, not only ensuring the safety of use, but also preventing large particle dust from directly entering the interior of the device and protecting the internal elements.

[0024] It should be noted that there is an unclear expression "卷入" in the original text, which may need to be further clarified in the original context. I have translated it as "being involved in" tentatively.Here, the display 101 is fixedly attached to the front of the handheld body 1, and a plurality of sets of control keys 102 are attached below the display 101 near the display 101. A speaker 103 is attached to one side of the handheld body 1. The display 101 located on the front of the handheld body 1 can display the screen taken by the camera 8 in real time. Therefore, the user can accurately view the subject and compose the picture, preview the taken photos / videos, and play back the recorded videos. Moreover, information such as the operating state of the fan and the power amount can also be displayed. By intensively arranging a plurality of sets of control keys 102 below the screen, it becomes easier for the user to operate with one hand, realizes flexible control of the shooting function, provides an operation prompt sound with the speaker 103, can play back the recorded voice or the voice of the video, and improves the user's interaction experience.

[0025] Here, inside the handheld body 1, a main board and a battery are attached. On one side of the main board, a TF card slot 106 and a power port 105 are attached. The built-in battery provides a power source that is easy to carry independently for the entire device, liberating it from dependence on a fixed power source. The main board integrates a core control circuit. The TF card slot 106 supports the insertion of a memory card, can simply save the taken photos and videos in a large capacity, is convenient for data transfer and backup. The power port 105 (for example, USB Type-C) is used to safely and efficiently charge the battery and ensure the duration of the device.

[0026] Here, an adjustment key 107 and a power switch 104 are attached to the other side of the handheld body 1, and a strap hole 108 is further provided at one end of the handheld body 1. The adjustment key 107 is used to adjust the airflow of the fan, improving flexibility of use. The independent power switch 104 allows the user to quickly turn the power of the entire device on / off, and the strap hole 108 allows the user to attach a wristband or strap, providing additional safety when using the device by hand, preventing it from accidentally slipping and being damaged, and improving the convenience and reliability of portable use.

[0027] The operating principle of this embodiment is as follows: After the user turns on the power switch 104, the battery inside the handheld body 1 supplies power to the entire system. The main board immediately starts up and initializes each function module. The user can select the fan speed level using the adjustment key 107 on the side of the handheld body 1. The main board controls the motor at the mounting bracket at the end of the inner cylinder 4 of the fan assembly to drive the fan blades 5 to rotate at high speed. Airflow is drawn in from the intake port, guided and accelerated in the inner cylinder 4, and then blown out from the air outlet of the front fixing ring 11, providing the user with directional cooling. Additionally, the camera 8, which is integrated on the outside of the fixing frame at the center of the rear fixing ring 7, is activated. Its field of view is located at the center of the intake port, effectively avoiding obstruction by the rotation of the fan blades 5, and allowing for a clear forward image. This image data is transmitted in real time to the main board of the handheld body 1 for processing and displayed on the front display 101, providing the user with a view and preview of the subject. The user can execute a command to take a photo or record video by controlling key 102, and the recorded video is stored on a memory card inserted into the TF card slot 106. Throughout the operation, the fan assembly is connected to the handheld body 1 via connecting arm 3, making it easy to adjust the airflow and shooting angles. The outer cylinder 2, the inner cylinder 4, and the rear fixing ring 7 and front fixing ring 11, which tightly fit into the locking block structure via connecting claws, together constitute a stable and robust support structure, ensuring the stability of the motor and camera 8's operation. After use of the device is complete, the battery can be charged via power port 105, and a strap can be attached to the strap hole 108 to improve carrying safety.
