DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1 - Fig.13A smart lock with monitoring and early warning function includes a smart lock body 1 and a sensor 46.

An outer wheel 21 is fixedly connected to the outer wall of the driven gear 20, and a swing arm 22 is rotatably connected to the outer wall of the outer wheel 21.

[0021] Contact plates 36 are fixedly connected to both sides of the interior of the shielding cover 2, and the inner wall of the contact plate 36 is slidably connected to the mounting plate 25. The end of the swing arm 22 away from the outer wheel 21 is rotatably connected to the outer wall of the mounting plate 25. A pressing rod 17 is slidably connected to the mounting plate 25, and pressing magnets 29 are provided on both sides of the pressing rod 17. A pressure plate 23 is provided at the end of the pressing rod 17.

[0022] A plurality of cleaning brushes 41 are arranged on the pressure plate 23, one end of the pressing rod 17 away from the pressure plate 23 penetrates to the outside of the shielding cover 2, and a trigger magnet is arranged on the outer wall. A sliding groove corresponding to the pressing rod 17 is opened on the shielding cover 2, and resistance teeth 47 are arranged on both sides of the pressing rod 17. Elastic rods 28 corresponding to the resistance teeth 47 are arranged on both sides of the mounting plate 25, and the ends of the elastic rods 28 are in sliding contact with the resistance teeth 47.

[0023] A plurality of spray tubes 38 are arranged inside the mounting plate 25, and an extrusion rod 37 is slidably connected to the interior of each of the spray tubes 38. A side plate 26 is arranged at the tail of the contact plate 36, and the end of the extrusion rod 37 is fixedly connected to the side plate 26. An exhaust pipe 31 and an infusion box 32 are connected to the inner wall of the spray tube 38, and a telescopic tube 27 is connected to the interior of the infusion box 32. One end of the telescopic tube 27 away from the infusion box 32 is connected to the interior of the liquid storage tank 16, and a baffle 35 is slidably connected to the interior of the exhaust pipe 31 and the infusion box 32.

[0024] The baffle plate 35 is respectively provided with a flow hole 39 and a through hole 40, and both ends of the baffle plate 35 are fixedly connected with a side magnetic block 30 and a side magnetic block 42. The magnetic poles of the side magnetic block 30 and the pressing magnetic block 29 are opposite, and the magnetic poles of the side magnetic block 42 and the pressing magnetic block 29 are the same. A plurality of reset grooves are provided inside the mounting plate 25, and a support plate 34 is slidably connected to the inner side wall of the reset groove, and the support plate 34 is fixedly connected to the baffle plate 35. A pressing spring 33 is arranged inside the reset groove, and the other end of the pressing spring 33 is in contact with the support plate 34.

[0025] The end of the spray barrel 38 is connected to a spray pipe 49 , the spray pipe 49 is in sliding contact with the pressure plate 23 , and a branch pipe 24 is provided at the end of the spray pipe 49 .

[0026] An upper magnetic stripe 3 and a lower magnetic stripe 4 are respectively arranged on the smart lock body 1. The upper magnetic stripe 3 has an opposite magnetic pole to the trigger magnet, and the lower magnetic stripe 4 has the same magnetic pole as the trigger magnet. A password input area 6 is arranged on the smart lock body 1, and a locking protection mechanism is arranged inside the smart lock body 1.

[0027] In this embodiment, when the password is required to open the smart lock body 1, the shielding cover 2 can be pushed up. At this time, the pressing rod 17 on the shielding cover 2 is located on the positive side of the lower magnetic strip 4 (refer to Fig.14 ), under the action of the repulsive magnetic force between the lower magnetic strip 4 and the trigger magnet on the pressing rod 17, the pressing rod 17 will push the pressing plate 23 to move towards the direction close to the password input area 6 until the cleaning brush 41 at the bottom of the pressing plate 23 contacts the password input area 6. When the shielding cover 2 is pushed up, the rollers 19 located on both sides of the shielding cover 2 will contact and rotate with the outer wall of the smart lock body 1 during the upward movement of the shielding cover 2. When the rollers 19 rotate, the driven gear 20 will be driven to rotate through the driving gear 18. Since the wheel diameter of the driving gear 18 is larger than the driven gear 20, when the driving gear 18 rotates, it can drive the driven gear 20 to rotate relatively quickly. When the driven gear 20 drives the outer wheel 21 to rotate synchronously and quickly, it will be driven by the swing arm 22 pushes the entire mounting plate 25 to reciprocate in the contact plate 36. When the mounting plate 25 swings back and forth, it drives the cleaning brush 41 on the pressure plate 23 to scrape and clean the password input area 6 back and forth. When the mounting plate 25 swings back and forth, allowing the pressure plate 23 to scrape and clean the password input area 6 back and forth, the extrusion rod 37 located in the spray barrel 38 will also swing with the mounting plate 25 and perform reciprocating suction movement in the spray barrel 38. According to the above principle, when the pressing rod 17 is pushed down, the pressing magnetic block 29 will move down synchronously with the pressing rod 17 and move away from the positive side of the side magnetic block 30. When the pressing magnetic block 29 moves away from the positive side of the side magnetic block 30, at this time, under the elastic force of the pressing spring 33, the entire baffle 35 will move to the right (refer to Figure 5), when the baffle 35 moves to the right, the flow hole 39 will enter the air extraction pipe 31, so that the through hole 40 moves out of the infusion box 32, and the infusion box 32 is blocked again by the unopened part of the baffle 35. Under the above principle, when the extrusion rod 37 performs reciprocating suction movement in the spray cylinder 38, the air extraction pipe 31 will suck the external air into the spray cylinder 38 through the flow hole 39 inside it, and then spray it to the password input area 6 through the spray pipe 49 and the branch pipe 24, and the reciprocating scraping of the cleaning brush 41 will clean the password. The input area 6 is cleaned. When the shielding cover 2 moves to the top of the smart lock body 1 to expose the entire password input area 6, the cleaning brush 41 cooperates with the wind blown out by the branch pipe 24 to clean the entire surface of the password input area 6, which can effectively prevent the password input area 6 from having any input traces left and the password from being deciphered. When the shielding cover 2 moves to the top of the smart lock body 1, the pressing rod 17 on the shielding cover 2 is located on the right side of the upper magnetic strip 3. Under the action of the magnetic force of attraction between the two, the pressing rod 17 will move upward.

[0028] See also Figure 1 - Fig.14 This embodiment further explains Example 1. The locking protection mechanism includes a bottom box 8 arranged on the smart lock body 1, a push plate 9 is slidably connected to the inside of the bottom box 8, a plug-in protrusion 48 is provided on the side wall of the push plate 9, an electric telescopic rod 10 is provided on the outer wall of the push plate 9, a rack 11 is provided at the end of the electric telescopic rod 10, a tension spring 12 is provided at the tail of the push plate 9, and the end of the tension spring 12 away from the push plate 9 is fixedly connected to the inner wall of the bottom box 8.

[0029] The smart lock body 1 is internally rotatably connected with a handle 13, and a one-way bearing 15 is arranged inside the bottom box 8. A gear 14 is rotatably connected to the one-way bearing 15. The gear 14 is meshed with the rack 11. The handle 13 slides through the gear 14 and the inside of the one-way bearing 15. A plurality of one-way plates 45 are rotatably arranged inside the gear 14. Reset springs 44 are fixedly connected to the outer walls of the plurality of one-way plates 45, and one end of the reset spring 44 away from the one-way plate 45 is fixedly connected to the inner wall of the gear 14.

[0030] A one-way toothed disc 43 is fixedly sleeved on the outside of the handle 13 , and the one-way plate 45 is in sliding contact with the one-way toothed disc 43 .

[0031] In this embodiment, after the password is entered, the operator can release the shielding cover 2. When the shielding cover 2 is released, the shielding cover 2 will move downward along the driving rail 5 under the action of its own gravity. When the shielding cover 2 moves downward, the roller 19 will still drive the driven gear 20 to rotate through the driving gear 18, and under the action of the swing arm 22, the mounting plate 25 will reciprocate in the contact plate 36. Under the above principle, when the shielding cover 2 moves to the top of the smart lock body 1 and then moves downward, the pressing rod 17 at this time moves upward. When the pressing rod 17 moves upward, the cleaning brush 41 at the bottom of the pressing plate 23 will be driven to move upward synchronously, and will no longer contact the surface of the password input area 6. When the pressing rod 17 moves upward, the pressing magnetic blocks 29 on both sides of the pressing rod 17 will come to the positive sides of the side magnetic blocks 30 and the side magnetic blocks 42 respectively. When the pressing magnetic block 29 on one side comes to the positive side of the side magnetic block 30, suction will be generated. When the pressing magnetic block 29 on the other side of the pressing rod 17 comes to the positive side of the side magnetic block 42, repulsive thrust will be generated. Therefore, under the combined action of suction generated on the left and thrust generated on the right (refer to Fig. 9 ), the baffle 35 will overcome the elastic force of the pressing spring 33 and move to the left. When the baffle 35 moves to the left, the through hole 40 will enter the infusion box 32, and the flow hole 39 will move out of the air extraction pipe 31. The unopened part of the baffle 35 will block the air extraction pipe 31 again. When the air extraction pipe 31 is blocked and the infusion box 32 is circulated again, as the mounting plate 25 reciprocates, the extrusion rod 37 performs a reciprocating suction motion in the spray cylinder 38. At this time, the spray cylinder 38 will pass through the infusion box 32 and the telescopic tube 27. The disinfecting alcohol in the liquid storage tank 16 is sucked into the interior thereof, and then sprayed onto the password input area 6 through the branch pipe 24 to disinfect the password input area 6 until the entire shielding cover 2 completely covers the password input area 6, thereby ensuring the safety of the entire smart lock body 1. During the up and down movement of the shielding cover 2, the traces are cleaned first and then disinfected, which ensures the input safety of the password input area 6 while avoiding input traces such as dust and other dirt on the password input area 6, which affects the disinfection and sterilization effect of the disinfecting alcohol.

[0032] During use, if the sensor 46 monitors and recognizes an unfamiliar face, the sensor 46 will drive the electric telescopic rod 10 to extend through the built-in controller (this is a prior art and will not be elaborated on in detail), so that the rack 11 is in contact and meshing with the gear 14. When the stranger enters an incorrect password through the password input area 6 as described above, and repeatedly presses the handle 13 to try to open the smart lock body 1, the pressed and flipped handle 13 will drive the one-way toothed disc 43 to rotate clockwise at a certain angle. When the one-way toothed disc 43 rotates clockwise, the one-way plate 45 will press against the right-angled side of the one-way toothed disc 43, thereby driving The gear 14 rotates synchronously by a certain angle. When the gear 14 rotates synchronously by a certain angle, it will drive the meshing rack 11 to move a certain distance to the right. When the handle 13 is pressed to the bottom, the handle 13 is released. The handle 13 will rotate counterclockwise and rebound to its original position under the action of its own elastic force. When the handle 13 drives the one-way toothed disc 43 to return to its original position counterclockwise, the one-way plate 45 will continuously contact the beveled edge of the one-way toothed disc 43 until it returns to its original position. Since the handle 13 is frequently pressed, the above process is repeated, and the intermittent clockwise rotating gear 14 will drive the rack 11 to move to the right side of the bottom box 8 (refer to Figure 2 ), until the push plate 9 is against the side of the bottom box 8. When the push plate 9 is against the side of the bottom box 8, the position of the rack 11 will be fixed. After the rack 11 is fixed, the gear 14 will be locked, so that the handle 13 cannot be pressed. When the handle 13 is locked, the sensor 46 will sound and light alarm (this is the prior art and will not be elaborated on). Since the handle 13 is usually connected to the lock body through a rectangular square pin, when the handle 13 is locked, the square pin will be fixed. Even if the lawless elements can break the lock core, they cannot drive the mechanical structure inside the lock body by rotating the handle 13 because the handle 13 is locked. , so that it cannot be opened, further ensuring the safety of the entire smart lock body 1, and in the process of the rack 11 driving the electric telescopic rod 10 to move to the side of the bottom box 8 and locking the handle 13, if the shielding cover 2 just returns to its original position to block the password input area 6, the buckle 7 on the shielding cover 2 will be inserted into the bottom box 8 and located on the positive side of the plug-in protrusion 48. When the push plate 9 moves to the positive side of the bottom box 8, the plug-in protrusion 48 will be inserted into the buckle 7 to fix the buckle 7, thereby locking the shielding cover 2 and shielding the entire password input area 6 to prevent criminals from damaging the password input area 6.

[0033] It should be noted that, under the above principle, when the through hole 40 enters into the infusion box 32 and the circulation hole 39 is away from the exhaust pipe 31, the spray gun 38 only sprays alcohol and does not discharge air, because the exhaust pipe 31 for sucking air has been blocked; correspondingly, when the circulation hole 39 enters into the exhaust pipe 31 and the through hole 40 moves out of the infusion box 32, the spray gun 38 only discharges air and does not spray alcohol, because the infusion box 32 for sucking alcohol is also blocked by the unopened part of the baffle 35, and the exhaust pipe 31, the infusion box 32 and the spray gun 49 are all provided with a one-way valve, which can ensure that the exhaust pipe 31 and the infusion box 32 only draw air and suck alcohol, and the spray gun 49 only sprays air or alcohol.

[0034] It should be noted that under the action of the one-way bearing 15, the gear 14 can only rotate clockwise. Therefore, when the handle 13 is released and rebounds, the gear 14 will not rotate under the inertia of the handle 13. When the alarm is lifted and the handle 13 needs to be used normally, it is only necessary to retract the electric telescopic rod 10 to disengage the rack 11 from contact with the gear 14. At this time, under the tension of the tension spring 12, the push plate 9 will drive the rack 11 back to its original position. Without the blocking limit of the rack 11, the one-way bearing 15 can rotate clockwise normally, and the handle 13 can also be used normally.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
