This makes it easy to disassemble and replace the sponge block 10 when it becomes dirty or worn after long-term use, thereby improving the practicality of use.

[0033] Specifically, a square plug hole matching the square plug block 91 is provided on the top of the mounting plate 8 , and a guide groove matching the guide rod 95 is provided at one end of the square plug block 91 .

[0034] By adopting the above technical solution, the square plug hole is convenient for inserting the square plug block 91 to fix the mounting plate 8, and the guide groove is convenient for cooperating with the guide rod 95, so that the square plug block 91 can slide stably.

[0035] When this embodiment is in use: pull the pull rod 92, the pull rod 92 moves to drive the fixed slider 93 to move and compress the fixed spring 94, so that the square plug block 91 is disengaged from the square plug hole, and then the mounting plate 8 can be removed and the sponge block 10 can be replaced. This makes it easy to disassemble and replace the sponge block 10 when it becomes dirty or worn after long-term use, thereby improving the practicality of use.

[0036] The structure and use principle of the smart fingerprint lock body 1, battery body 2, fingerprint reader 5 and operation panel 6 in the utility model have been disclosed in a fingerprint smart lock based on the Internet of Things disclosed in Chinese patent application number 202122288902.8. Its working principle is that when the user needs to unlock, the user moves the toggle block so that the toggle block drives the slide cover 7 to move upward, exposing the operation panel 6 and fingerprint reader 5 in the slot, and then reads the fingerprint through the fingerprint reader 5 to unlock, or enters the password through the operation panel 6 to unlock, and then after the unlocking is completed, the user enters the password through the operation panel 6. The sliding cover 7 is driven by the toggle block to move downward, so that the sliding cover 7 completely covers the operation panel 6 and the fingerprint reader 5, so that the sliding cover 7 can protect the operation panel 6 and the fingerprint reader 5, and prevent the operation panel 6 and the fingerprint reader 5 from being hit or scratched by foreign objects, which may affect the normal operation of the operation panel 6 and the fingerprint reader 5. When the sliding cover 7 moves downward, the sponge block 10 is driven to move downward, and the sponge block 10 is tightly attached to the inner wall of the groove, so that the sponge block 10 can wipe the operation panel 6 and the fingerprint reader 5 during the downward movement, and wipe off the dust on the surface of the operation panel 6 and the fingerprint reader 5.

[0037] The working principle and use process of the utility model: According to the utility model, when the user needs to unlock, the user moves the toggle block so that the toggle block drives the slide cover 7 to move upward to expose the operation panel 6 and the fingerprint reader 5 in the slot, and then reads the fingerprint through the fingerprint reader 5 to unlock, or enters the password through the operation panel 6 to unlock, and then after the unlocking is completed, the toggle block drives the slide cover 7 to move downward so that the slide cover 7 completely covers the operation panel 6 and the fingerprint reader 5, so that the slide cover 7 can protect the operation panel 6 and the fingerprint reader 5, and prevent the operation panel 6 and the fingerprint reader 5 from being hit or scratched by foreign objects, affecting the normal operation of the operation panel 6 and the fingerprint reader 5, and when the slide cover 7 moves downward, it drives the sponge block 10 to move downward, and the sponge block 10 is in close contact with the inner wall of the slot, so that the sponge block 10 can wipe the operation panel 6 and the fingerprint reader 5 during the downward movement, and wipe off the dust on the surface of the operation panel 6 and the fingerprint reader 5, and when the battery body 2 needs to be replaced, the cover 3 can be quickly opened and closed through the convenient switch assembly 4. , replace the battery body 2, and disassemble the assembly 9 to facilitate the disassembly of the mounting plate 8 to replace the sponge block 10. When the convenient switch assembly 4 is in use, the push rod 42 is pushed, and the push rod 42 drives the fixed rod 41 to move. The movement of the fixed rod 41 will drive the extrusion block 43 to move and compress the reset spring 44, so that the fixed rod 41 is separated from the fixed hole. When the push rod 42 moves to the maximum limit, it pushes the limit plate 421 to move, and the limit plate 421 moves to the inside of the smart fingerprint lock body 1, thereby limiting the push rod 42 to prevent it from rebounding, and then the cover can be closed. The cover 3 is removed, so that when the device is in use, it is convenient to open and close the cover 3 and replace the battery body 2, which improves the practicality of use. When the disassembly and assembly component 9 is in use, the pull rod 92 is pulled, and the movement of the pull rod 92 drives the fixed slider 93 to move and compress the fixed spring 94, so that the square plug block 91 is disengaged from the square plug hole, and then the mounting plate 8 can be removed and the sponge block 10 can be replaced. When the device is in use, it is convenient to disassemble and replace the sponge block 10 when it becomes dirty or worn after long-term use, which improves the practicality of use.
