It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0022] The utility model provides a technical solution: Figure 1-6 The utility model discloses a multifunctional attendance device, including a device body 1, which is mainly divided into three parts: a shell 11, a face recognizer 12 and a fingerprint recognizer 13. The face recognizer 12 and the fingerprint recognizer 13 are fixedly installed in the shell 11. The recognition end of the face recognizer 12 and the recognition end of the fingerprint recognizer 13 are extended to the outside of the shell 11 and are respectively arranged coplanar with the front side of the shell 11 and the right side of the shell 11. A cleaning mechanism 2 is provided on the outside of the shell 11, and an adjustment mechanism 3 is provided at the bottom end of the cleaning mechanism 2.
[0023] In the present embodiment, when the improved attendance device is used, as the face recognizer 12 detects that someone is approaching the face recognizer 12 to a certain distance, the adjusting mechanism 3 drives the cleaning mechanism 2 to operate, and the fingerprint recognizer 13 recognition end is disinfected by the cleaning mechanism 2 to prevent the user from contacting harmful debris when placing the finger on the fingerprint recognizer 13 recognition end, and the fingerprint recognizer 13 recognition end and the face recognizer 12 recognition end are cleaned at the same time, so that the face recognizer 12 recognition end and the fingerprint recognizer 13 recognition end can clearly perform face and fingerprint recognition processing, and perform user identity recognition through fingerprint information and face information, and avoid the external environment affecting the recognition effect of the device body 1, and after the device is used, the adjusting mechanism 3 drives the cleaning device to reset, and automatically completes the shielding of the fingerprint recognizer 13 recognition end, which can prevent chalk powder from adhering to the recognition end of the fingerprint recognizer 13 and affecting the use of the attendance device.
[0024] In a further preferred embodiment of the present invention, Figure 1-4As shown, the cleaning mechanism 2 includes a fixing plate 21, which is arranged on the right side of the housing 11, and the fixing plate 21 and the housing 11 are clearance-matched, a sponge plate 22 and a rubber ring 23 are fixedly installed in the fixing plate 21 from top to bottom, and the bottom side of the sponge plate 22 is fixedly connected to the top side of the rubber ring 23, a water-absorbing plate 24 is fixedly installed in the rubber ring 23, and the side of the rubber ring 23 close to the housing 11, the side of the sponge plate 22 close to the housing 11 and the side of the water-absorbing plate 24 close to the housing 11 are all in contact with the right side wall of the housing 11;
[0025] In this embodiment, due to the fit between the rubber ring 23 and the right side wall of the housing 11 , a relatively closed space is formed inside the rubber ring 23 , thereby preventing the alcohol or disinfectant in the rubber ring 23 from invading the sponge board 22 and affecting the use of the sponge board 22 .
[0026] In a further preferred embodiment of the present invention, Figure 5 As shown, a water storage tank 25 is provided in the fixing plate 21, and the water storage tank 25 is located below the rubber ring 23. A plurality of guide strips 26 are provided in the water storage tank 25, and the top of each guide strip 26 penetrates the rubber ring 23 and is fixedly connected to the fixing plate 21, the rubber ring 23 and the bottom side of the water absorption plate 24. A waterproof bolt 27 is threadedly installed at the position corresponding to the water storage tank 25 on the other side of the fixing plate 21, and the threaded end of the waterproof bolt 27 is inserted into the water storage tank 25.
[0027] In this embodiment, the operator needs to periodically unscrew the waterproof bolt from the fixing plate 21, and then pour a suitable amount of alcohol into the water storage tank 25 through the hole of the fixing plate 21. Then, the guide strip 26 continuously absorbs the alcohol or disinfectant in the water storage tank 25, and pours a certain amount of alcohol or disinfectant into the water absorption plate 24, so that the water absorption plate 24 contains a certain amount of alcohol or disinfectant, and the water absorption plate 24 is stored in the above-mentioned closed space, which can prevent external sunlight from shining on the water absorption plate 24, causing the alcohol or disinfectant to vaporize and escape.
[0028] In a further preferred embodiment of the present invention, Figure 6 As shown, a support plate 28 in an L-shape is fixedly installed on the front side of the top of the fixing plate 21, and the support plate 28 is gap-matched with the shell 11, and a sponge strip 29 is fixedly installed in the support plate 28, and the side of the sponge strip 29 close to the shell 11 is connected to the front side wall of the shell 11;
[0029] In this embodiment, the support plate 28 is arranged so that the support plate 28 can move together with the fixing plate 21, thereby driving the sponge strip 29 to slide along the recognition end of the face recognizer 12 and move to the bottom of the recognition end of the face recognizer 12, thereby sweeping away the debris on the recognition end of the face recognizer 12;
[0030] When the fixing plate 21 is reset, the supporting plate 28 can be driven to move above the recognition end of the face recognizer 12, so that after the face recognizer 12 detects that someone is approaching the face recognizer 12 to a certain distance or after the operator moves away from the recognition end of the face recognizer 12, the adjustment mechanism 3 is controlled to operate, thereby avoiding excessive power consumption by the adjustment mechanism 3 and the fingerprint recognizer 13 and other mechanisms due to long-term operation.
[0031] In a further preferred embodiment of the present invention, Figure 1 As shown, the adjustment mechanism 3 includes a magnetic strip 31, which is fixedly mounted on the bottom side of the fixed plate 21, a battery magnet is provided below the magnetic strip 31, and an electromagnet 32 is fixedly connected to the outer wall of the housing 11;
[0032] In this embodiment, when the face recognizer 12 detects that a person is approaching the face recognizer 12 to a certain distance, the electromagnet 32 is activated, and the fixed plate 21 is pulled downward by the attraction between the electromagnet 32 and the magnetic strip 31 .
[0033] In a further preferred embodiment of the present invention, Figure 5 As shown, two guide rods 33 are installed in the fixed plate 21 for relative sliding penetration, and the sponge plate 22, the rubber ring 23 and the water storage tank 25 are all located between the two guide rods 33, the bottom ends of the guide rods 33 are fixedly connected to the housing 11, and the outer peripheral side of the guide rods 33 is wound with a spring 34, and the two ends of the spring 34 are respectively fixedly connected to the fixed plate 21 and the bottom ends of the corresponding guide rods 33;
[0034] In this embodiment, when the fixing plate 21 moves downward, the spring 34 can be compressed synchronously, and when the fixing plate 21 moves downward, due to the mutual interference between the guide rod 33 and the fixing plate 21, the fixing plate 21 moves up and down in a linear trajectory, so that the sponge plate 22, the water absorption plate 24 and the sponge strip 29 always slide in contact with the outer wall of the housing 11;
[0035] After the operator moves away from the recognition end of the face recognizer 12, the electromagnet 32 is turned off, and the suction force between the magnetic strip 31 and the electromagnet 32 disappears. Due to the push of the spring 34 on the fixed plate 21, the fixed plate 21 and the support plate 28 automatically move up and reset, thereby completing the shielding of the recognition end of the fingerprint recognizer 13 through the fixed plate 21.
[0036] Working principle: Before using the improved attendance equipment, the operator needs to unscrew the waterproof bolt from the fixing plate 21, and then pour a proper amount of alcohol into the water tank 25 through the hole of the fixing plate 21, and then the guide bar 26 continuously absorbs the alcohol or disinfectant in the water tank 25, and pours a certain amount of alcohol or disinfectant into the water absorption plate 24, so that the water absorption plate 24 contains a certain amount of alcohol or disinfectant;
[0037] After the water absorption plate 24 absorbs a certain amount of alcohol or disinfectant into the water absorption plate 24 through the guide strip 26, the rubber ring 23 is tightly fitted with the right side wall of the housing 11, so that the water absorption plate 24 is located in a relatively closed space, thereby preventing external sunlight from irradiating the water absorption plate 24 and causing the alcohol or disinfectant to vaporize and escape;
[0038] During the use of the improved attendance equipment, as the face recognizer 12 detects that someone is approaching the face recognizer 12 to a certain distance, the electromagnet 32 is activated. Due to the attraction between the electromagnet 32 and the magnetic strip 31, the fixed plate 21 moves downward and compresses the spring 34. As the fixed plate 21 moves, the water absorption plate 24 and the sponge plate 22 slide against the identification end of the fingerprint recognizer 13. The water absorption plate 24 disinfects the identification end of the fingerprint recognizer 13, and the sponge plate 22 wipes off the residual liquid on the identification end of the fingerprint recognizer 13.
[0039] During the downward movement of the fixing plate 21, the sponge strip 29 can be driven by the supporting plate 28 to slide along the recognition end of the face recognizer 12 and move to the bottom of the recognition end of the face recognizer 12, thereby sweeping away the debris on the recognition end of the face recognizer 12;
[0040] After the face recognition device 12 and the fingerprint recognition device 13 have been cleaned, the user places his finger on the fingerprint recognition device 13 to identify the user through the fingerprint. At the same time, the face recognition device 12 can perform face recognition on the user and compare it with the information in the device body 1 to determine whether the fingerprint information and the face information are the same. If the face information and the fingerprint information do not match, the punch-in is unsuccessful. If the face information and the fingerprint information match, the punch-in is successful.
[0041] After the above-mentioned operator successfully clocks in, the user moves his finger away from the recognition end of the fingerprint identifier 13, and at the same time the operator moves away from the recognition end of the face identifier 12. At this time, the face identifier 12 detects that the user has completed the attendance clock-in, the electromagnet 32 is turned off, and the suction force between the magnetic strip 31 and the electromagnet 32 disappears. Due to the push of the spring 34 on the fixed plate 21, the fixed plate 21 and the support plate 28 move up and reset, thereby re-shielding the recognition end of the fingerprint identifier 13 through the fixed plate 21 to prevent external debris from adhering to the recognition end of the fingerprint identifier 13.
[0042] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
