[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] As per the instruction manual Figure 1 , 2 As shown in Figures 3 and 4, to facilitate battery replacement of the UPS 1, the miniature UPS 1 typically designs the battery as a pull-out removable battery 12, which is connected to the housing 11 of the UPS 1 via a snap-fit ​​structure. The connection method can be referenced to the snap-fit ​​connection of a household light switch. The housing 11 of the UPS 1 contains a battery compartment 111 for storing the pull-out removable battery 12 and a chip partition 112 for mounting the control circuit board 13. The outer side of the chip partition 112 has a control panel 14 for controlling the output circuit. The control panel 14 has a display screen 141, an output voltage adjustment button 142, and a status indicator light 143. The control circuit board 13 monitors and controls the output voltage of the pull-out removable battery 12. It includes a voltage output regulation system that controls the output voltage via the adjustment button 142, a low-voltage circuit breaker system for protection, and an abnormality indication system for controlling the indicator light. Furthermore, to facilitate control of the shutdown countdown, the control circuit board 13 has a timing system for detecting available time.

[0022] To facilitate maintenance of the control circuit board 13, the control panel 14 is located on the outer wall of the chip partition 112. The top surface of the chip partition 112 is an open end, and a cover 1121 connected by a pin is provided above the open end of the top surface of the chip partition 112.

[0023] To ensure that the pull-out removable battery 12 can be stably connected to the control circuit board 13 when inserted into the battery compartment 111, the chip separator 112 and the battery compartment 111 are provided with a power terminal 15 for connecting the pull-out removable battery 12, and the bottom surface of the pull-out removable battery 12 is provided with an arrow indicating the insertion direction.

[0024] To ensure stable output of the UPS uninterruptible power supply 1 when the removable pull-out battery 12 is replaced, a replacement backup battery 2 is provided on the inner wall of the cover 1121 by a snap-fit. A timer 3 for monitoring the usable time of the replacement backup battery 2 and a switch 4 for changing the output power are provided above the control panel 14. The timer 3 and the switch 4 are both connected to the replacement backup battery 2 through the control circuit board 13. The replacement backup battery 2 has an internal timing system for detecting the usable time. The timing system of the replacement backup battery 2 shares the same system as the usable countdown of the removable pull-out battery 12, and the timing mode is changed by the switch 4.

[0025] In a specific implementation of this invention, when the removable pull-out battery 12 experiences insufficient voltage, the timing system for available time inside the control circuit board 13 will be triggered, and a timing signal will be sent to the abnormality warning system. Subsequently, the abnormality warning system will trigger the abnormality indicator light 143. When the user discovers the abnormality, they will press the switch 4 to use the backup power source of the replacement battery 2 and complete the replacement of the removable pull-out battery 12 before the timer 3 expires. After the replacement is completed, the switch 4 will be pressed again to switch the output voltage source back. After the switch is back, the abnormality warning system will detect the normal voltage and switch the indicator light 143 back to the normal state. After the switch is back, the replacement battery 2 will enter the charging state, ready for the next backup.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
