[0024] In an embodiment of the present utility model: The bottom case 2 is connected to the top side of the portable Wi-Fi 1 through a buckle. The battery cover 3 is slidably connected to the front end of the top side of the bottom case 2. A cotton pad is arranged on one side of the battery cover 3 close to the 18650 battery 5.

[0025] In one embodiment of the utility model: a plurality of heat dissipation holes 7 are provided at the rear ends of the left and right sides of the top of the portable wifi 1, and an elastic band 13 is provided at the middle of the side of the connecting rod 11 away from the portable wifi 1.

[0026] In one embodiment of the present invention: a charging interface 8 is provided at one end of the rear side of the portable wifi 1, and a dust cover is provided at one end of the charging interface 8 away from the portable wifi 1.

[0027] In one embodiment of the present utility model: a storage compartment 6 is provided on the rear side wall of the portable wifi 1, the width of the storage compartment 6 is slightly larger than the width of the baffle 9, and one end of the storage compartment 6 is connected to the charging port 8.

[0028] In one embodiment of the utility model: both ends of the 18650 battery 5 are connected to an anti-reverse discharge circuit, which is composed of an NMOS tube and a resistor. A main board is arranged inside the portable wifi 1 near the battery slot 4, and a thermal control element is arranged on the main board.

[0029] In one embodiment of the present invention, the two card interfaces 15 are respectively located at the upper and lower sides of the storage bin 6 , and the two card interfaces 15 are not on the same horizontal plane.

[0030] Example 1, please refer to the attached Figure 1 -Attached Figure 4 Through the design of a detachable battery, a combination of a fixed part and a movable part is designed, which can be quickly connected and separated from the fixed part, providing users with the possibility of selecting appropriate battery capacity according to different needs and improving utilization efficiency; and through the setting of an anti-reverse discharge circuit, unknown dangers caused by reverse connection of the battery are avoided.

[0031] Specifically, an anti-reverse discharge circuit is connected to both ends of the 18650 battery 5, which is composed of an NMOS tube and a resistor. The MOS tube acts as a switch: when the battery is installed correctly, the voltage is directly applied to the G gate, the Vgs voltage increases, and the MOS tube is turned on, and the portable WiFi works normally; when the battery is installed in reverse, the G gate is connected to the negative electrode of the battery, Vgs is less than 0V, and the MOS tube is turned off, so that the battery is disconnected from the mainboard, which plays a role in preventing reverse discharge.

[0032] Example 2, please refer to the attached Figure 1 -Attached Figure 4 Through the cooperation of the storage compartment 6, the baffle 9, the telescopic column 10, the connecting rod 11, the clamping block 12 and other components, the spare battery is combined with the device, which further improves the portability of the battery and avoids the situation of battery life anxiety and inability to use the spare battery because it cannot be found.

[0033] Specifically, the elastic band 13 is pulled outward to drive the connecting rod 11 to move, so that the clamping block 12 and the telescopic column 10 connected to the connecting rod 11 move synchronously. When the clamping block 12 is disengaged from the card interface 15 below, the connecting rod 11 is rotated to rotate 90° around the telescopic column 10, and the limit of the baffle 9 is released. The baffle 9 is opened to put the spare battery into the storage bin 6 or take the spare battery out of the storage bin 6.

[0034] Working principle:

[0035] First, slide the battery cover 3 outward and place the 18650 battery 5 in the battery slot 4 for use with the portable wifi 1. Because the battery can be quickly connected and separated from the portable wifi 1, it is easy to carry and replace, providing great convenience for users in various occasions. In addition, because the 18650 battery 5 has added anti-reverse discharge protection, it is achieved through the NMOS tube, which completely cuts off the discharge current to protect the battery, and at the same time prevents the adverse reaction caused by reverse connection due to the use of uncertain battery polarity, that is, the anti-reverse discharge circuit is connected at both ends of the 18650 battery 5, which is composed of an NMOS tube and a resistor. The MOS tube acts as a switch here: when the battery is correctly installed, the voltage is directly applied to the G gate, and the Vgs voltage increases. At this time, the MOS tube is turned on, and the portable WiFi works normally. When the battery is installed in reverse, the G gate is connected to the negative pole of the battery, Vgs is less than 0V, and the MOS tube is cut off, so that the battery is disconnected from the motherboard, which plays a role in preventing reverse discharge.

[0036] When a spare battery is needed or placed, the elastic band 13 is pulled outward to drive the connecting rod 11 to move synchronously. Since the clamping block 12 is connected to the left end of the connecting rod 11 and the telescopic column 10 is connected to the right end of the connecting rod 11, when the connecting rod 11 moves outward, the clamping block 12 and the telescopic column 10 move synchronously. When the clamping block 12 is disengaged from the card interface 15 below, the connecting rod 11 is rotated so that it rotates 90° around the telescopic column 10 and moves to above the baffle 9. At this time, the connecting rod 11 releases the limit of the baffle 9, and the baffle 9 is opened to put the spare battery into the storage bin 6 or take the spare battery out of the storage bin 6. At this point, the entire workflow is completed.

[0037] The above-mentioned front, back, left, right, top and bottom are all based on the figures in the specification. Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
