[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] refer to Figure 1-3 A dustproof and anti-theft smart door lock includes a door lock body 1, a password button 11 and a fingerprint recognition switch 12 arranged on the door lock body 1, and also includes: a groove 2, which is opened on the door lock body 1, and the password button 11 and the fingerprint recognition switch 12 are both installed in the groove 2; a mounting groove 3, which is opened above the groove 2; a cover plate 4, which is vertically guided and installed in the mounting groove 3; a touch switch 5, which is installed on the top of the mounting groove 3, and the password button 11 and the fingerprint recognition switch 12 are started and closed by pressing and separating the touch switch 5 by the cover plate 4; a driving component 6, which is installed in the door lock body 1, drives the cover plate 4 up and down, and then closes and opens the groove 2. It can be understood that the depth of the groove 2 can completely accommodate the password button 11 and the fingerprint recognition switch 12, and then the cover plate 4 can be smoothly moved down to close the groove 2. The mounting groove 3 provides space for the cover plate 4 to accommodate and move up and down. The guide installation of the cover plate 4 can install slide rails on both sides of the installation groove 3, and install slides that slide with the slide rails on both sides of the cover plate 4. Of course, guide matching structures such as shaft holes can also be used. For the start and close of the driver, it can be started by wirelessly connecting to the mobile terminal APP, mobile phone, computer, etc. In this way, when opening the door, the drive component 6 is started by the APP to drive the cover plate 4 to move up and fully open the groove 2. The top of the cover plate 4 is pressed on the touch switch 5, and the password button 11 and the fingerprint recognition switch 12 are started, and people can operate. When leaving home, the APP pneumatic drive component 6 drives the cover plate 4 to move down to seal the groove 2, the top of the cover plate 4 is separated from the touch switch 5, and the password button 11 and the fingerprint recognition switch 12 are closed. In this way, even if an outsider knows the password and damages the cover plate 4 by opening a hole, the password button 11 and the fingerprint recognition switch 12 cannot be operated.

[0029] In some embodiments, the top of the mounting groove 3 is provided with a receiving groove 51 with an opening facing downward, and the touch switch 5 is completely located in the receiving groove 51; the top of the cover plate 4 is provided with a protrusion 41 that engages with the opening to touch the touch switch 5. In this way, the touch switch 5 is completely located in the receiving groove 51, and the touch switch 5 can only be triggered when the cover plate 4 is completely raised to the top and the protrusion 41 is inserted from the opening into the receiving groove 51, thereby ensuring the stability of the touch.

[0030] In some embodiments, a cavity 7 is provided in the door lock body 1, which is located above the groove 2 and connected to the mounting groove 3, and the drive assembly 6 is installed in the cavity 7. Furthermore, the drive assembly 6 includes a rack 61 installed on the inner side of the cover plate 4 and arranged vertically, and a motor at the bottom of the cavity 7; a gear 62 meshing with the rack 61 is installed at the output end of the motor. It can be understood that the purpose of connecting the cavity 7 with the mounting groove 3 is to enable the rack 61 on the cover plate 4 to extend into the cavity 7 and cooperate with the motor. Of course, the drive assembly 6 can also use devices such as electric push rods and threaded screw transmissions. In this way, the gear 62 is driven to rotate by the forward and reverse rotation of the motor, and cooperates with the rack 61 to realize the automatic up and down movement of the cover plate 4.

[0031] In some embodiments, a limit switch 9 is installed on one side of the mounting slot 3 of the door lock body 1, and a telescopic driver 8 that drives the limit switch 9 to do telescopic work; when the telescopic driver 8 drives the limit switch 9 to extend, the cover plate 4 is located below the limit switch 9; after the limit switch 9 is triggered, the password button 11 and the fingerprint recognition switch 12 are turned off. It can be understood that the telescopic driver 8 can also use electric push rods, threaded screw transmission and other devices, and the limit switch 9 can be connected to the touch switch 5, and the touch switch 5 will be turned off after being triggered. It can also be connected to the password button 11 and the fingerprint recognition switch 12, and the password button 11 and the fingerprint recognition switch 12 are directly turned off after being triggered. In this way, when the cover plate 4 moves down, the telescopic driver 8 drives the limit switch 9 to retract, so that the cover plate 4 cannot contact the dynamic switch when it moves down. After moving down to the bottom, the telescopic driver 8 drives the limit switch 9 to extend to limit the upward movement of the cover plate 4. At this time, the telescopic driver 8 will only drive the limit switch 9 to retract when the drive component 6 is operated by APP. If an outsider forcibly moves the cover plate 4 upward to trigger the touch switch 5, the limit switch 9 will be hit, and the password button 11 and the fingerprint recognition switch 12 will be turned off, thus further improving the anti-theft effect.

[0032] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
