[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0034] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the purpose of simplifying the description and do not indicate or imply that the orientation is a specific orientation or specific orientation structure and operation. Therefore, they should not be construed as limiting this utility model.

[0035] like Figures 1 to 5As shown, this utility model relates to a replaceable battery handheld fan, which includes a handle 1, a fan tube 2, a plug-in battery 3, a control component 4, and an execution component 5. The fan tube 2 is located at the top of the handle 1, and an air duct 201 is formed in the fan tube 2, which is connected to both the front and rear ends of the fan tube 2. The front end of the fan tube 2 is the air outlet of the air duct 201, and the rear end is the air inlet. The execution component 5 is located in the air duct 201. When the execution component 5 is running, it pushes the air to flow from the air inlet to the air outlet, generating wind, thereby reducing airflow. The handle 1 has a mounting cavity 101 inside, which is a through cavity that communicates with the top and bottom of the handle 1. A wiring port 202 is provided at the bottom of the air duct 2 corresponding to the mounting cavity 101, connecting the air duct 201 of the air duct 2 to the mounting cavity 101 of the handle 1. A plug-in battery 3 is inserted into the mounting cavity 101 from the lower end and is detachably connected to the bottom of the handle 1. A control component 4 is located in the mounting cavity 101 and is connected to the plug-in battery. The battery 3 and the actuator 5 are electrically connected. This invention uses a removable plug-in battery 3 as a power source, replacing the built-in battery commonly used in existing handheld fans. This allows users to easily replace the plug-in battery 3 when it ages or its performance deteriorates, without having to replace the entire device. Furthermore, its large capacity supports long-term fan operation, resulting in low charging dependence and eliminating the need for frequent charging. This makes it better suited for use in environments without electricity. In addition, the lower end of the mounting cavity 101 is sealed by the plug-in battery 3. The handle 1 and the fan shroud 2, which are connected to each other, prevent the connection point between the mounting cavity 101 and the wiring port 202 from communicating with the external space, maintaining good sealing between the mounting cavity 101 and the wiring port 202. This effectively prevents dust and dirt from entering the plug-in battery 3 and the control assembly 4, avoiding short circuits, poor contact, or performance degradation caused by dust accumulation. It also isolates moisture and humidity, preventing dampness and corrosion, extending service life, and improving the safety of using the fan of this invention.

[0036] like Figures 1 to 5 As shown, the insertable battery 3 consists of three parts: a bottom cover 301, a housing 302, and a lithium battery 303. The housing 302 is located on top of the bottom cover 301 and is inserted into the mounting cavity 101. The bottom cover 301 covers the lower end of the mounting cavity 101. The insertable battery 3 is detachably connected to the handle 1 through the bottom cover 301. A cavity is formed between the housing 302 and the bottom cover 301. The lithium battery 303 is located in the cavity between the bottom cover 301 and the housing 302 and is protected by the bottom cover 301 and the housing 302. The lithium battery 303 is inserted into the mounting cavity 101 of the handle 1 along with the housing 302. The control component 4 is electrically connected to the lithium battery 303, and the lithium battery 303 supplies power to the entire circuit.

[0037] like Figures 1 to 5As shown, the bottom cover 301 has a push switch 301a, a first L-shaped latch 301b, and a deformation groove 301c. The push switch 301a is located on the outer wall of the bottom cover 301. The deformation groove 301c is opposite to the push switch 301a. The first L-shaped latch 301b is formed on the push switch 301a, which allows the push switch 301a to bend towards the deformation groove 301c when pressure is applied, and drives the first L-shaped latch 301b to rotate towards the center of the bottom cover 301. A first locking groove 101a is formed on the inner wall of the mounting cavity 101, and the first L-shaped latch 301b is fastened to the push switch 301a. When the first L-shaped latch 301b engages with the first locking groove 101a, the insert battery 3 is locked to the handle 1. When the push switch 301a is pressed, the first K-shaped latch rotates and disengages from the first locking groove 101a, releasing the engagement. At this time, the insert battery 3 can be removed from the handle 1 for replacement. The entire disassembly process only requires a simple pressing action on the push switch 301a. When reinstalling the replaced insert battery 3, first ensure that the first L-shaped latch 301b and the first locking groove 101a are aligned, and then remove the cover 302 and... The internal lithium battery 303 is inserted into the mounting cavity 101 of the handle 1. During insertion, the first L-shaped latch is rotated towards the deformation groove 301c by the pressure from the lower opening of the mounting cavity 101, thus allowing the first L-shaped buckle 301b to enter the interior of the mounting cavity 101. When this pressure is removed, the first L-shaped buckle 301b returns to its original shape due to the material properties, thereby engaging with the first locking groove 101a and fixing the inserted battery 303 to the handle 1. It should be noted that in order to ensure that the pressure from the lower opening of the mounting cavity 101 is better applied to the first L-shaped latch 301 when the inserted battery 3 is reinstalled, additional pressure is applied to the first L-shaped latch 301b. On the L-shaped buckle 301b, the top of the first L-shaped buckle 301b is inclined, so that when force is applied, the first L-shaped buckle 301b can rotate in the direction of the deformation groove 301c. In order to prevent the push switch 301a from slipping when pressed by the user, the push switch 301a has anti-slip texture. In order to make the fixation between the insert battery 3 and the handle 1 more secure, there are two sets of the first L-shaped buckle 301b and the corresponding first locking groove 101a, which are located on the left and right sides of the handle 1 and the insert battery 3. This increases the number of fixing points between the insert battery 3 and the handle 1, ensuring a secure connection.

[0038] like Figure 4 As shown, the number of lithium batteries 303 is four, thereby increasing the capacity of the plug-in battery 3. This will significantly increase the continuous running time of the handheld fan of this invention, further reduce the dependence on charging, and allow it to be used freely even in environments without electricity.

[0039] Furthermore, the air blower 2 is detachably connected to the handle 1. The air blower 2 can be a regular handheld fan or an ice pack handheld fan. Based on the above settings, the air blower 2 can be configured according to the user's actual needs. More specifically, it allows the air blower 2 of a regular handheld fan and the air blower 2 of an ice pack handheld fan to be interchanged, ensuring that the user receives better cooling in hot weather.

[0040] like Figures 7 to 10 As shown, a mounting base 102 is formed on the top of the handle 1. The mounting base 102 is a boss structure that surrounds the upper end of the mounting cavity 101. A second L-shaped buckle 102a and a baffle 102b are formed on the front and rear sides of the mounting base 102, respectively. A second locking groove 202a and a slot 202b are provided on the front and rear sides of the wiring port 202. The second locking groove 202a corresponds to the second L-shaped buckle 102a, and the locking groove corresponds to the baffle 102b. The mounting base 102 is inserted into the wiring port 202, the second L-shaped buckle 102a is fastened in the second locking groove 202a, and it is inserted into the air duct 201 through the slot 202b. A positioning block 201a is formed in the air duct 201. The baffle 102b and the positioning block 201a are fixed by threaded fasteners 6. In the inserted state, the second L-shaped buckle restricts the air duct 2 to the top of the handle 1, preventing the air duct 2 from moving up and down relative to the handle 1. The baffle 102b restricts the left and right movement and deflection of the air duct 2 relative to the handle 1. The threaded fastener 6 allows the side of the mounting base 102 with the baffle 102b to be fixed to the air duct 2. When the air duct 2 needs to be replaced, simply remove the threaded fastener 6. This allows the air duct 2 to be rotated with the mating position of the second L-shaped buckle 102a and the second locking groove 202a as the fulcrum. During the rotation, the baffle 102b can disengage from the air duct 201 and the slot 202b. Then, the second L-shaped buckle 102a can be separated from the second locking groove 202a, and the air duct 2 can be removed for replacement. Similarly, in order to securely fix the air duct 2 to the handle 1, there are two sets of the second L-shaped buckle 102a and the corresponding second locking groove 202a, and two sets of the baffle 102b. This increases the number of fixing points between the air duct 2 and the handle 1, ensuring a secure connection.

[0041] like Figure 6 and Figure 9 As shown, the execution component 5 includes a fan unit 501, a cooling semiconductor 502, and a metal sheet 503. The fan unit 501 and the cooling semiconductor 502 are both electrically connected to the control component 4. The metal sheet 503 is attached to the cooling semiconductor 502. The metal sheet 503 and the cooling semiconductor 502 are covered with a cover plate 7. The air duct 2 with the above-mentioned execution component 5 is an ice-cooling handheld fan. When running, the temperature of the cooling semiconductor 502 decreases, and the low temperature is conducted to the airflow through the air duct 201 through the metal sheet 503, thereby reducing the temperature of the airflow. The low-temperature air blown out by the air duct 2 can bring a cool experience to the user in hot weather.

[0042] like Figure 6 As shown, the execution component 5 also includes a heat sink 504, and the cooling semiconductor 502 is attached to the heat sink 504. The function of the heat sink 504 is to provide heat dissipation for the cooling semiconductor 502, thereby preventing the cooling semiconductor 502 from getting too hot during the operation of the handheld fan of this utility model, and ensuring that the cooling semiconductor 502 has a better cooling effect.

[0043] like Figure 1 , Figure 2 , Figure 6 , Figure 11 and Figure 12 As shown, the control component 4 includes a control circuit board 401, a control switch 402, and a charging interface 403. The control switch 402, the charging interface 403, the plug-in battery 3, and the execution component 5 are all electrically connected to the control circuit board 401. The control circuit board 401 has a chip for receiving control commands and controlling the operating state of the execution component 5. The control switch 402 and the charging interface 403 are fixed to the outer wall of the handle 1. The control switch 402 is used to control the start and stop of the handheld fan of this utility model and can perform gear shifting operations, thereby controlling the airflow speed blown out by the fan tube 2. The charging interface 403 is used to connect the power cord to charge the plug-in battery 3, so that the plug-in battery 3 can be recycled. The charging interface 403 is covered with a dust cover 8. The dust cover 8 can be rotated to open the charging interface 403. When the cover is on the charging interface 403, it can effectively prevent dust, dirt, and other impurities from entering and avoid poor contact.

[0044] like Figure 2 , Figure 6 , Figure 11 and Figure 12 As shown, the control component 4 also includes a display screen 404, which is electrically connected to the control circuit board 401 and fixed to the outer wall of the handle 1. The display screen 404 can display the remaining power of the plug-in battery 3, the operating speed, and the running time, so that the user can intuitively understand the operating status of the fan and help the user replenish the power of the plug-in battery 3 in a timely manner.

[0045] Combination Figures 1 to 12In use, the user controls the operation of this handheld fan via the control switch 402 on the outer wall of the handle 1. When the fan tube 2 is a cooling handheld fan, the temperature of the cooling semiconductor 502 decreases during operation. The low temperature is conducted through the metal plate 503 to the airflow through the air duct 201, thus lowering the airflow temperature. The low-temperature air blown out by the fan tube 2 provides a cooler experience for the user. During operation, the speed can be switched again via the control switch 402. The speed information, the remaining power of the plug-in battery 3, and the running time are all displayed on the screen 404. When the power of the plug-in battery 3 is low, the user can open the dust cover 8 covering the charging port 403 and charge it using the power cord. The inserted battery 3 is designed to be removable. Users can press the push switch 301a on the bottom cover 301 of the inserted battery 3 to rotate the first L-shaped buckle 301b towards the deformation groove 301c to disengage it from the first locking groove 101a. This allows the inserted battery 3 to be directly removed from the handle 1 for replacement. At the same time, after the threaded fastener 6 between the air blower 2 and the positioning block 201a is released, the air blower 2 can be rotated with the engagement position of the second L-shaped buckle 102a and the second locking groove 202a as the fulcrum. During the rotation, the baffle 102b can disengage from the air duct 201 and the slot 202b. After that, the second L-shaped buckle 102a can be separated from the second locking groove 202a, and the air blower 2 can be removed for replacement.

[0046] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of this utility model.
