A mosquito repellent mechanism 5 is embedded in the middle of the front of the wooden door 2 along the up and down directions.

[0029] The self-locking mechanism 4 includes a shell 41 fixedly connected to the upper right corner of the front face of the door frame 1, a motor 42 is installed at the right end of the upper surface of the shell 41, a driving gear 43 is installed at the output end of the motor 42, a positioning component 44 is embedded at the left end of the upper surface of the shell 41, a timer 45 electrically connected to the motor 42 is installed at the rear side of the shell 41, and the motor 42 is started regularly by the timer 45, a rotating shaft 46 capable of rotating around its own axis is installed on the left side of the inner cavity of the shell 41 through a bearing, and a rotating disk 47, a driven gear 48 and a first connecting rod 49 are installed on the outer wall of the rotating shaft 46 from top to bottom, and the driven gear 48 is meshed and connected with the driving gear 43, and the transmission ratio of the driving gear 43 to the driven gear 48 is greater than 1. When 42 drives the active gear 43 to rotate, the active gear 43 drives the driven gear 48 to rotate more labor-saving, so that the first connecting rod 49 pulls the wooden door 2 to rotate more labor-saving, and a plurality of positioning holes 410 are equidistantly arranged on the outer edge of the upper surface of the turntable 47 along the circumferential direction, and the turntable 47 is braked by cooperating with the positioning holes 410 through the positioning assembly 44, and a groove 411 is arranged on the side wall of the turntable 47, and a first contact 412 entering the groove 411 is installed on the left inner wall of the shell 41, and the first contact 412 is electrically connected to the timer 45, and the end of the first connecting rod 49 away from the rotating shaft 46 is connected to one end of the second connecting rod 413 through a pin shaft, and the other end of the second connecting rod 413 is connected to the top of the front face of the wooden door 2 through a pin shaft.

[0030] As a preferred solution, further, the positioning assembly 44 includes a sleeve 441 embedded in the left end of the upper surface of the housing 41, and the upper and lower ends of the right inner wall of the sleeve 441 are respectively embedded with a first permanent magnet 442 and a second contact 443, and the second contact 443 is externally connected to a power supply, and the inner cavity of the sleeve 441 is plugged with a pull rod 444 that can slide up and down, and the upper and lower ends of the right side wall of the pull rod 444 are respectively embedded with a second permanent magnet 445 and a third contact 446, and the second permanent magnet 445 and the first The permanent magnet 442 magnetically attracts the pull rod 444 to position the third contact 446, and is electrically connected to the second contact 443 and the turntable 47. The outer wall of the pull rod 444 is rectangular in shape to prevent the second permanent magnet 445 and the third contact 446 from rotating. An insertion rod 447 is installed at the bottom end of the pull rod 444. When the insertion rod 447 moves downward and is inserted into the positioning hole 410, the turntable 47 is braked. The bottom of the insertion rod 447 is conical in shape, which facilitates the insertion of the insertion rod 447 into the positioning hole 410.

[0031] As a preferred embodiment, further, the mosquito repellent mechanism 5 includes a storage box 51 embedded in the middle of the front side of the wooden door 2 along the up and down directions, a switch assembly 52 is installed at the left end of the upper surface of the storage box 51, one end of a cover plate 53 is installed at the bottom of the inner cavity of the storage box 51 through a pin shaft, and the other end of the cover plate 53 is connected to the bottom of the switch assembly 52, a lampshade is installed on the outer wall of the cover plate 53 along the up and down directions, and a mosquito repellent lamp 54 is installed in the inner cavity of the lampshade. When the cover plate 53 rotates, the mosquito repellent lamp 54 can be stored in the storage box 51 to ensure the beauty of the wooden door 2. When the mosquito repellent lamp 54 is powered on, it emits yellow light that mosquitoes hate, and drives mosquitoes away from the human body.

[0032] As a preferred solution, further, the switch assembly 52 includes an outer cover 521 embedded in the left end of the upper surface of the storage box 51, a metal plate 522 is installed on the top of the inner cavity of the outer cover 521, the metal plate 522 is externally connected to a power supply, and insulating grooves 523 are provided at both ends of the lower surface of the metal plate 522. A limit sleeve 524 that can slide up and down and rotate is inserted into the inner cavity of the outer cover 521, and protrusions 525 electrically connected to the mosquito repellent lamp 54 are installed on both sides of the upper surface of the limit sleeve 524. The upper and lower ends of the limit sleeve 524 are respectively inserted with elastic The spring 526 and the spline shaft 527, the bottom end of the spline shaft 527 is connected to the top of the cover plate 53, and the limit sleeve 524 is pushed upward under the elastic force of the spring 526. When the protrusion 525 enters the insulating groove 523, the limit sleeve 524 is positioned. When the protrusion 525 contacts the metal plate 522, the mosquito repellent lamp 54 is powered on and works. The protrusion 525 is in the shape of an arc. When the spline shaft 527 drives the limit sleeve 524 to rotate, the protrusion 525 can be lowered under the obstruction of the insulating groove 523, allowing the protrusion 525 to move out of the insulating groove 523.

[0033] Working principle:

[0034] Step 1: Inputting a fingerprint on the cover of the fingerprint lock 3 can open the wooden door 2. During the rotation of the wooden door 2, the second connecting rod 413 pulls the first connecting rod 49 to rotate, thereby causing the rotating shaft to drive the turntable 47 and the driven gear 48 to rotate counterclockwise, and the first contact 412 comes out of the groove 411 and contacts the side wall of the turntable 47. A closed loop is formed between the second contact 443, the third contact 446, the turntable 47, the first contact 412 and the timer 45, and the timer 45 starts timing. When the timer 45 reaches the timing time, the timer 45 drives the motor 42, and the motor 42 drives the driving gear 43 to rotate counterclockwise, thereby causing the driven gear 48 to drive the first connecting rod 49 to rotate clockwise, allowing the second connecting rod 413 to push the wooden door 2 to close, thereby achieving the purpose of self-locking the wooden door 2.

[0035] Step 2: When the wooden door 2 needs to be opened for a long time, after opening the wooden door 2, the pull rod 444 is pressed down to separate the second permanent magnet 445 from the first permanent magnet 442, and the third contact 446 from the second contact 443. The timer 45 is powered off, and the insertion rod 447 is inserted into the positioning hole 410 at the corresponding position to position the turntable 47. The second connecting rod 413 stays at the current position, and the wooden door 2 is always open.

[0036] Step three, before entering the room, pull the cover plate 53 outwards, causing the spline shaft 527 to drive the limit sleeve 524 to rotate, and the protrusion 525 is squeezed out from the insulating groove 523. The elastic force of the spring 526 makes the protrusion 525 contact the metal plate 522, and the mosquito repellent lamp 54 is powered on to light up, repelling mosquitoes from the body of the person entering the room to prevent mosquitoes from being brought into the room.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
