Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to an intelligent handheld fan. Background Technology

[0002] With the advancement of technology and the improvement of living standards, people have increasingly higher demands for the comfort and convenience of daily necessities. Although traditional handheld fans are portable, they have certain limitations in use. For example, they cannot automatically adjust the switch according to the ambient temperature, and the handle area is prone to heat buildup, affecting the user experience.

[0003] In the prior art, the Chinese patent document with publication number CN211501026U, "Intelligent Handheld Fan," proposes a sensor that senses human body temperature or the distance between the human body and the fan, as well as a processor that can store the fan's last adjusted speed and restore the last speed when the fan is turned on again. This makes the fan's start-up and speed adjustment more intelligent. However, in practical applications, the use of the fan often requires manual operation of the switch, which affects the user experience. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose an intelligent handheld fan to solve the problem that the existing technology cannot operate autonomously according to the ambient temperature, which affects the user experience.

[0005] To achieve the above objectives, this utility model provides an intelligent handheld fan, including a handle. A bimetallic strip is movably installed inside the handle. A limiting block is fixedly connected to the lower part of the bimetallic strip. A rotating rod is rotatably connected to the limiting block. A knob is fixedly connected to one side of the rotating rod. The knob is located on the outside of the handle and rotatably connected to the handle. The bimetallic strip is a split structure with one rectangular side and one U-shaped side. The rectangular side is fixedly connected to the inner wall of the handle, and the U-shaped side is fixed to the limiting block. It is slidably disposed inside the handle.

[0006] Preferably, the grip has a plurality of air holes fixedly formed thereon, and the grip has a groove fixedly formed inside, with the air holes communicating with the groove.

[0007] Preferably, a power button is fixedly installed on the grip, and a wire is fixedly connected to the power button. The wire is fixed to the bimetallic strip, and the other side of the bimetallic strip is also provided with the wire, the other end of which is connected to a battery.

[0008] Preferably, a base is inserted into the bottom of the grip, a rear frame is fixedly connected to the top of the grip, a front cover is rotatably snapped onto one side of the rear frame, and a fan blade is rotatably connected inside the rear frame.

[0009] Preferably, the U-shaped portion of the bimetallic sheet is a thermosensitive material.

[0010] Preferably, the power button, the wire, the bimetallic strip, and the battery are electrically connected.

[0011] Preferably, the outer surface of the grip is provided with a thermoplastic elastomer material.

[0012] The beneficial effects of this utility model are:

[0013] 1. This intelligent handheld fan uses a temperature-sensitive bimetallic strip to power on the fan when the temperature exceeds a preset value, eliminating the need for manual on / off operation. When adjustments to the triggered temperature are required, they can be easily made using a knob, enhancing the fan's practicality.

[0014] 2. This intelligent handheld fan, through its interconnected air duct design, allows the handle to be cooled during operation, thereby improving the grip and user experience. It also cools the internal components of the fan, maintaining the internal operating temperature, extending the fan's lifespan, and further enhancing its practicality. Attached Figure Description

[0024] like Figures 1 to 4As shown, a smart handheld fan includes a handle 1. A bimetallic strip 10 is movably installed inside the handle 1. A limiting block 12 is fixedly connected to the lower part of the bimetallic strip 10. A rotating rod 13 is rotatably connected to the limiting block 12. A knob 6 is fixedly connected to one side of the rotating rod 13. The knob 6 is located on the outside of the handle 1 and is rotatably connected to the handle 1. The bimetallic strip 10 is a split structure with one rectangular side and one U-shaped side. The rectangular side is fixedly connected to the inner wall of the handle 1, and the U-shaped side is fixedly and slidably disposed inside the handle 1 with the limiting block 12. The interaction between the limiting block 12, the rotating rod 13, and the knob 6 can personalize the distance between the bimetallic strips 10, thereby adapting to different temperatures for start-up. The U-shaped part of the bimetallic strip 10 is a heat-sensitive material, which allows the bimetallic strip 10 to deform at higher temperatures, thereby causing the U-shaped part to contact the rectangular part to form a circuit, enabling the fan to operate. The outer surface of the handle 1 is provided with a thermoplastic elastomer material, which can prevent hand fatigue caused by prolonged holding. The handle 1 has multiple air holes 7 fixedly opened on it, and a groove 9 fixedly opened inside the handle 1. The air holes 7 are connected to the groove 9. This design ensures that air can enter the groove 9 through the air holes 7 when the fan is working, thereby accelerating the airflow of the handle 1 and thus producing a cooling effect on the handle 1. A power button 5 is fixedly installed on the handle 1. A wire 11 is fixedly connected to the power button 5. The wire 11 is fixed to the bimetallic strip 10. A wire 11 is also provided on the other side of the bimetallic strip 10. The other end of the wire 11 is connected to the battery 14. The power button 5, the wire 11, the bimetallic strip 10 and the battery 14 are electrically connected. The multiple electrically connected components can ensure that the fan is powered off when it is not in use, thereby avoiding power waste. A base 2 is inserted into the bottom of the handle 1, and a rear frame 3 is fixedly connected to the top of the handle 1. A front cover 4 is rotatably snapped onto one side of the rear frame 3. The fan blade 8 is rotatably connected inside the rear frame 3. This design makes the fan more coordinated and practical.

[0025] Workflow: When the fan is working, first press the power button 5 to provide basic electrical power. When the temperature around the fan rises, the U-shaped part of the bimetallic strip 10 will deform and bend, making it contact the rectangular part. At this time, the circuit is completed, and the current drives the fan blade 8 to rotate through the built-in motor. At this time, because the air is pushed by the fan blade 8, the air inside the groove 9 is also pulled and blown out. The air will then enter the interior of the groove 9 through the air hole 7, thereby cooling the handle 1. When the temperature drops, the bimetallic strips 10 move away from each other, forming a circuit break. At this time, the fan stops rotating. When it is necessary to adjust the temperature limit that triggers the fan to work, the operation knob 6 can be rotated to make the rectangular part and the U-shaped part of the bimetallic strip 10 move away from each other or move closer together.
