[0023] Please see Figure 1This invention provides the following technical solution: a shopping mall marketing customer flow identification system, including multiple cameras and a cash register inside the store. The multiple cameras are respectively set at the store entrance to monitor the flow of people entering the store. The data output end of the cameras is connected to a human body recognition module to identify the human body entering the store in real time. The data output end of the human body recognition module is connected to a human body counting module to count the number of people entering the store by time period. The data output end of the human body counting module is connected to an analysis module. At the same time, the data output end of the cash register is connected to the analysis module. Therefore, the cash register transmits sales data to the analysis module. The analysis module combines the sales data and the actual number of people entering the store in each time period to analyze the traffic conversion rate of the store in each time period.

[0024] Please see Figures 2-9 The present invention provides a new technical solution based on the above-mentioned scheme: a camera, including a body 1, a bracket 2 is provided on the top of the body 1, the body 1 is mounted on the wall of the shopping mall through the bracket 2, a groove is provided on the front of the body 1, a lens 4 is provided on the inner wall of the groove, and a fill light 5 is provided on the inner wall of the groove directly below the lens 4. Therefore, the fill light 5 provides supplementary lighting to the shooting scene, ensuring the clarity of the image captured by the lens 4.

[0025] The bottom of the body 1 is provided with a base block 3. An L-shaped heat dissipation cavity 7 is opened on the upper surface of the base block 3. The vertical cavity on the rear side of the L-shaped heat dissipation cavity 7 extends into the rear side of the body 1. An exhaust fan 6 is embedded in the rear surface of the body 1, which penetrates into the vertical cavity of the L-shaped heat dissipation cavity 7. A heat dissipation base plate 8 is provided on the bottom wall of the body 1. Electronic components with high heat generation inside the body 1 are mounted on the heat dissipation base plate 8. Multiple heat dissipation fins 9 are arranged in parallel left and right on the lower surface of the heat dissipation base plate 8. The lower sides of the multiple heat dissipation fins 9 penetrate into the horizontal cavity of the L-shaped heat dissipation cavity 7 and are connected to its bottom wall. The heat dissipation base plate 8 and the heat dissipation fins 9 are both made of materials with high thermal conductivity.

[0026] When the camera is in use, the electronic components inside the body 1 generate heat. Since the heat dissipation base plate 8 and the heat dissipation fins 9 are made of materials with high thermal conductivity, the heat is conducted to the L-shaped heat dissipation cavity 7 through the heat dissipation base plate 8 and the heat dissipation fins 9. At the same time, the exhaust fan 6 is started, which can draw out the hot air in the L-shaped heat dissipation cavity 7, thereby achieving the purpose of dissipating the heat.

[0027] A cylindrical conveying cavity 12 is provided inside the bottom block 3. A connecting cavity 11 is provided inside the bottom block 3 between the L-shaped heat dissipation cavity 7 and the cylindrical conveying cavity 12. The connecting cavity 11 is funnel-shaped. Multiple first ventilation slots 10 communicating with the connecting cavity 11 are provided on the bottom wall of the horizontal cavity of the L-shaped heat dissipation cavity 7. The first ventilation slots 10 are located between two heat dissipation fins 9. Multiple second ventilation slots 13 communicating with the cylindrical conveying cavity 12 are provided on the bottom wall of the connecting cavity 11. A dust suction slot 14 is provided on the bottom wall of the groove on the front of the body 1. The dust suction slot 14 is also funnel-shaped. The bottom of the dust suction slot 14 is connected to the front side of the cylindrical conveying cavity 12.

[0028] During use, when the exhaust fan 6 draws air from the L-shaped heat dissipation cavity 7, the internal air pressure of the L-shaped heat dissipation cavity 7 decreases, thus creating a negative pressure at the dust suction groove 14. This allows external cold air to enter the cylindrical conveying cavity 12 through the dust suction groove 14, and then sequentially pass through the second ventilation groove 13, the connecting cavity 11, and the first ventilation groove 10 to the L-shaped heat dissipation cavity 7. This achieves heat exchange for the heat dissipation fins 9, ensuring the camera's heat dissipation efficiency during long-term operation. Simultaneously, due to the negative pressure effect of the dust suction groove 14, dust or lint near the lens 4 and the supplementary light 5 enters the cylindrical conveying cavity 12 under the negative pressure, minimizing the accumulation of dust on the lens 4 during long-term monitoring of passenger flow, which would affect the monitoring effect. Furthermore, the camera's heat dissipation components provide real-time cleaning of dust on the lens 4, eliminating the need for regular cleaning by staff and reducing their workload.

[0029] The inner wall of the front side of the cylindrical conveying cavity 12 is rotatably connected to a first rotating shaft 15. The outer surface of the first rotating shaft 15 is fitted with an auger blade 16. At the same time, the outer surface of the auger blade 16 is in contact with and slides against the inner wall of the cylindrical conveying cavity 12. Multiple filter holes 17 are opened on the surface of the auger blade 16 near the bottom and front side of the connecting cavity 11. The diameter of the second ventilation slot 13 is smaller than the diameter of the dust.

[0030] During use, because the auger blades 16 have filter holes 17, the auger blades 16 do not obstruct the airflow. However, when dust enters the cylindrical conveying chamber 12 with the airflow, the dust is blocked by the auger blades 16 and does not flow with the airflow. At this time, the first rotating shaft 15 drives the auger blades 16 to rotate. Therefore, the auger blades 16 can convey the dust that has entered the cylindrical conveying chamber 12 backward. At the same time, the diameter of the second ventilation slot 13 is smaller than the diameter of the dust. When the dust is conveyed to the bottom of the connecting chamber 11, the dust will not enter the connecting chamber 11 with the airflow. Since the filter holes 17 are only opened on the surface of the auger blades 16 near the bottom and front of the connecting chamber 11, when the dust is conveyed beyond the bottom of the connecting chamber 11, it will not be affected by the airflow. This ensures the dust collection effect and minimizes the possibility of dust entering the L-shaped heat dissipation chamber 7 with the airflow, which would affect the heat dissipation of the heat dissipation fins 9.

[0031] A collection chamber 18 is provided inside the bottom block 3. The collection chamber 18 is connected to the rear end of the cylindrical conveying chamber 12. The rear end of the first rotating shaft 15 and the rear side of the auger blade 16 both extend into the collection chamber 18. A drawer 19 is slidably connected to the bottom wall of the collection chamber 18. One side of the drawer 19 slides through the outer surface of the bottom block 3.

[0032] During use, the auger blades 16 continuously transport dust backward into the collection chamber 18. When the dust is transported into the collection chamber 18, it falls into the drawer 19 under the action of inertia, thereby achieving the purpose of dust collection. At the same time, the dust can be cleaned simply by pulling out the drawer 19 later, which reduces the difficulty of operation for the staff.

[0033] A transmission block 20 is provided on the top wall of the collection cavity 18. A transmission cavity 21 is opened at the bottom of the transmission block 20. The rear end of the first rotating shaft 15 rotates through into the transmission cavity 21. A first bevel gear 22 is provided at one end of the first rotating shaft 15 located in the transmission cavity 21. A second bevel gear 23 is meshed on the first bevel gear 22. The diameter of the second bevel gear 23 is smaller than that of the first bevel gear 22. A second rotating shaft 24 is provided on the upper surface of the second bevel gear 23. The upper end of the second rotating shaft 24 rotates through into the vertical cavity of the L-shaped heat dissipation cavity 7. A fan blade 25 is provided at one end of the second rotating shaft 24 located in the L-shaped heat dissipation cavity 7.

[0034] When the exhaust fan 6 draws in hot air, the airflow will create a thrust on the fan blades 25, causing the fan blades 25 to drive the second rotating shaft 24 to rotate. The second bevel gear 23 rotates synchronously with the second rotating shaft 24, thus meshing with and driving the first bevel gear 22 to rotate, thereby synchronously driving the first rotating shaft 15 to rotate. Through the above simple mechanical structure, the airflow can be utilized and converted into driving force to drive the auger blades 16 to rotate, without the need for additional electric components, reducing the consumption of natural resources.

[0035] In actual use, due to the high density of people in shopping malls, dust inevitably contains flexible impurities such as clothing fibers and paper scraps. When these flexible impurities fall into drawer 19, they tend to accumulate due to their light weight, affecting the actual collection effect of drawer 19. Therefore, a pressure plate 26 is installed in the collection cavity 18. The pressure plate 26 is located directly above drawer 19, and its outer surface is in contact with the inner wall of drawer 19. Therefore, when in use, the pressure plate 26 is moved down and into drawer 19, which can flatten the flexible impurities that fall into drawer 19, making full use of the space inside drawer 19 and providing a good collection effect for impurities.

[0036] A through groove 27 is provided on the pressure plate 26. The through groove 27 is located directly below the auger blade 16. Impurities pushed by the auger blade 16 can fall into the drawer 19 through the through groove 27. Two swing plates 28 are provided in the through groove 27. The outer surface of the swing plates 28 is in contact with the inner wall of the through groove 27. When the two swing plates 28 are rotated to a horizontal position, their lower surfaces are flush with the pressure plate 26. Therefore, when the pressure plate 26 moves down, the two swing plates 28 rotate to a horizontal position. Thus, the lower side of the swing plates 28 can also flatten the impurities.

[0037] A fixing plate 32 is provided on the upper surface of the rear side of the pressure plate 26, and a first sleeve rod 33 is provided on the top wall of the collection cavity 18. The interior of the fixing plate 32 is hollow, and the lower end of the first sleeve rod 33 slides through the fixing plate 32. A first built-in plate 34 that slides in the fixing plate 32 is provided at the lower end of the first sleeve rod 33. A first spring 35 that is movably sleeved on the outer surface of the first sleeve rod 33 is provided between the upper surface of the first built-in plate 34 and the top wall of the fixing plate 32. When the first spring 35 is not compressed, the first spring 35 will exert a pushing force on the fixing plate 32, so that the fixing plate 32 pulls the pressure plate 26 to the middle position of the collection cavity 18, and the upper surface of the pressure plate 26 is flush with the bottom wall of the cylindrical conveying cavity 12.

[0038] A third rotating shaft 30 is provided on the rear surface of the first rotating shaft 15. The rear end of the third rotating shaft 30 rotates through the rear surface of the transmission block 20. A rotating disk 31 is provided at the rear end of the third rotating shaft 30. A connecting shaft 37 is provided on the rear surface of the rotating disk 31. The connecting shaft 37 is located at an eccentric position on the rotating disk 31. A transverse sliding plate 36 is provided on the front side of the fixed plate 32. A compensation component is provided between the transverse sliding plate 36 and the fixed plate 32. A transverse sliding groove 39 is provided on the front surface of the transverse sliding plate 36. The vertical cross-section of the transverse sliding groove 39 is circular. A sliding ball 38 is provided at the rear end of the connecting shaft 37, extending into the transverse sliding groove 39. At the same time, the sliding ball 38 slides in the transverse sliding groove 39.

[0039] In use, when the first rotating shaft 15 rotates, the third rotating shaft 30 rotates synchronously with the first rotating shaft 15. At this time, the rotating disk 31 rotates synchronously, while the connecting shaft 37 rotates eccentrically. The connecting shaft 37 drives the slider 38 to slide in the transverse sliding groove 39. During the sliding process, the slider 38 can generate a pushing or pulling force on the fixed plate 32, causing the fixed plate 32 to drive the pressure plate 26 to move downward or upward. At the same time, the fixed plate 32 slides on the first sleeve rod 33, and the first spring 35 can contract or extend.

[0040] The compensation component includes a compensation plate 48, which is disposed on the surface of the fixed plate 32 near the transverse slide plate 36. A compensation groove 49 is formed on the surface of the compensation plate 48 near the transverse slide plate 36. A mounting rod 50 is disposed between the upper and lower inner walls of the compensation groove 49. A mounting sleeve 51 is slidably fitted on the outer surface of the mounting rod 50. One side of the mounting sleeve 51 extends out of the compensation groove 49 and connects to the rear surface of the transverse slide plate 36. A second spring 52 is movably fitted on the outer surface of the mounting rod 50 between the lower surface of the mounting sleeve 51 and the bottom wall of the compensation groove 49. The strength of the second spring 52 is greater than that of the first spring 35. Therefore, when the fixed plate 32 is moved downward, the second spring 52 will not be compressed, thereby driving the fixed plate 32 to move downward.

[0041] When the pressure plate 26 presses down a thick layer of dust, since the displacement distance of the transverse slide plate 36 driven by the connecting shaft 37 is fixed, when the pressure plate 26 cannot press down the dust, the transverse slide plate 36 drives the mounting sleeve 51 to slide on the surface of the mounting slide rod 50. At the same time, the second spring 52 is stressed and contracts, which further improves the dust pressing effect.

[0042] Two swing plates 28 are each provided with a drive shaft 29 on the left and right surfaces away from one side. The other end of the drive shaft 29 is rotatably connected to the inner wall of the through groove 27. Two control cavities 40 are opened on the right side of the pressure plate 26. The right end of the right drive shaft 29 rotates through into the control cavity 40. A gear 41 is sleeved on the outer surface of the end of the drive shaft 29 located in the control cavity 40. A rack 42 is meshed on the lower side of the gear 41. Control grooves 45 are opened on the inner walls of the front and rear sides of the collection cavity 18. A contact push rod 43 is provided on the surface of the rack 42 facing the control groove 45. The other end of the contact push rod 43 slides through the surface of the pressure plate 26 and extends into the control groove 45. The rack 42 and the control cavity A first tension spring 44 is provided between the inner walls of 40 and is movably sleeved on the outer surface of the contact push rod 43. When the first tension spring 44 is not affected by the tension, the first tension spring 44 will exert a tension on the rack 42, so that the initial position of the rack 42 is close to the side of the control slide 45. This makes the initial position of the swing plate 28 tilted downward. A lifting block 46 is provided on the inner wall of the control slide 45 facing the pressure plate 26. The lifting block 46 is in the shape of a right trapezoid, and the inclined surface of the lifting block 46 is set upward. One end of the contact push rod 43 located in the control slide 45 contacts the inclined surface and the vertical surface of the lifting block 46 and slides. A plurality of movable grooves 47 are provided on the vertical surface of the lifting block 46.

[0043] When the pressure plate 26 moves downward, the contact push rod 43 moves downward synchronously with the pressure plate 26. When the contact push rod 43 slides to the inclined surface of the lifting block 46, the contact push rod 43 is squeezed by the inclined surface of the lifting block 46, causing the contact push rod 43 to move into the control cavity 40. The first tension spring 44 is stressed and stretched, and at the same time, the rack 42 meshes and drives the gear 41 to rotate, thereby causing the swing plate 28 to rotate upward. When the contact push rod 43 slides to contact the vertical surface of the lifting block 46, the adjacent side of the two swing plates 28 tilts upward slightly. When the contact push rod 43 slides to the movable groove 47, the first tension spring 44 pulls the contact push rod 43 to move into the movable groove 47, causing the swing plate 28 to rotate downward a little and rotate into a horizontal position. When it moves out of the movable groove 47, it tilts upward again. Because multiple movable grooves 47 are provided, the swing plate 28 can swing up and down in a small amplitude. In this way, when pressing impurities, the impurities can be knocked, which further improves the pressing effect on flexible impurities.
