[0025] The driving assembly 20 includes a bidirectional threaded screw 21 that is rotatably arranged inside the elevator car 10. Two sliding seats 22 are arranged on the surface of the bidirectional threaded screw 21. The sliding seats 22 are slidably connected to the inner wall of the elevator car 10. Two driving plates 23 are slidably arranged on the inner side of the elevator car 10 and on both sides of the bidirectional threaded screw 21. A plurality of limit rods 24 are fixedly installed on the separated sides of the two driving plates 23.

[0026] The driving motor 26 starts working, driving the bidirectional threaded screw 21 to rotate, and the bidirectional threaded screw 21 drives the sliding seat 22 to move outward. The sliding seat 22 drives the driving plate 23 to slide inward through the hinge rod 25. The driving plate 23 drives the limiting rod 24 to disengage from the inner side of the limiting hole 35, and pulls the filter frame 31 upward to disengage the mounting block 33 from the mounting groove, and disassembles the filter assembly 30, which is convenient for the staff to clean it and ensure the subsequent filtering effect.

[0027] The filter assembly 30 includes a filter frame 31 disposed inside the elevator car 10 and located on the left and right sides of the bidirectional threaded screw 21. The elevator car 10 is provided with a mounting opening adapted to the filter frame 31. A filter screen 32 is provided inside the filter frame 31. Mounting blocks 33 are fixedly installed on both the front and rear sides of the filter frame 31. Mounting holes are provided inside the mounting blocks 33.

[0028] The ventilation assembly 40 includes connecting frames 41 arranged at the four corners inside the elevator car 10. Connecting blocks 42 are arranged near the bottom inside the connecting frames 41. Ventilation openings are formed near the left and right sides inside the connecting blocks 42. A baffle 43 is rotatably arranged at the top of the connecting block 42. Fixed blocks are fixedly installed on the top of the connecting block 42 and on both sides of the baffle 43. Two elastic members 44 are arranged on the surface of each fixed block. One ends of the two elastic members 44 on the same side are commonly fixedly installed with positioning blocks 45 adapted to the baffle 43.

[0029] During the use of the device, the electric fan 46 starts to work, blowing the wind outside the elevator car 10 to the inside. The filter net 32 filters the blown wind and blows it to the inside of the elevator car 10 through the ventilation openings, achieving the purpose of ventilation and air exchange inside the elevator car 10 and improving comfort. In winter, the positioning block 45 is squeezed outward. The positioning block 45 squeezes the elastic member 44 to contract. The baffle 43 is manually rotated to block the ventilation opening. The reaction force of the elastic member 44 squeezes the positioning block 45, and the positioning block 45 fits on the surface of the baffle 43 and limits it. By screwing the threaded rod 48 into the inner side of the threaded hole 60, the stability of the baffle 43 is increased, so that the wind will not directly blow on the human body surface, avoiding the phenomenon that people feel cold when ventilating in winter. At the same time, the number of ventilation openings can be adjusted according to the use needs, greatly increasing the applicability of the device.

[0032] An electric fan 46 is communicated and arranged at the top of the connecting frame 41. The tops of the electric fans 46 penetrate through the elevator car 10 and the inside of the filter rack 31 and extend to the inside of the filter rack 31. A protective net is fixedly connected to the top of the electric fan 46 by bolts.

[0033] Two clamping blocks 47 are fixedly installed near the center inside the connecting frame 41. Clamping grooves adapted to the clamping blocks 47 are formed on the front and rear sides of the connecting block 42.

[0034] A threaded rod 48 penetrates through the center of the baffle 43 and the connecting block 42. The inner side wall of the connecting block 42 is threadedly arranged with the surface of the threaded rod 48. A threaded hole 49 adapted to the threaded rod 48 is formed near the center inside the connecting frame 41.

[0035] The working principle of the ventilation structure of the elevator car provided by the utility model is as follows:

[0036] Step 1: When the device is in use, the electric fan 46 starts to work, blowing the wind outside the elevator car 10 to the inside, the filter 32 filters the blown wind, and blows it to the inside of the elevator car 10 through the vent, so as to achieve the purpose of ventilation and air exchange inside the elevator car 10 and improve comfort. In winter, the positioning block 45 is squeezed outward, and the positioning block 45 squeezes the elastic member 44 to shrink, and the baffle 43 is manually rotated to block the vent. The reaction force of the elastic member 44 squeezes the positioning block 45, and the positioning block 45 fits on the surface of the baffle 43 and limits it. The threaded rod 48 is threadedly connected to the inside of the threaded hole 60, thereby increasing the stability of the baffle 43, so that it will not blow directly on the human body surface, avoiding the phenomenon of wind blowing and making people cold during ventilation in winter. At the same time, the number of vents can be adjusted according to the needs of use, which greatly increases the applicability of the device;

[0037] Step 2: The driving motor 26 starts to work, driving the bidirectional threaded screw 21 to rotate, and the bidirectional threaded screw 21 drives the sliding seat 22 to move outward. The sliding seat 22 drives the driving plate 23 to slide inward through the hinge rod 25. The driving plate 23 drives the limiting rod 24 to disengage from the inner side of the limiting hole 35, and pulls the filter frame 31 upward to disengage the mounting block 33 from the mounting groove, and disassembles the filter assembly 30 to facilitate the staff to clean it and ensure the subsequent filtering effect.

[0038] Compared with the related art, the ventilation structure of the elevator car provided by the utility model has the following beneficial effects:

[0039] By cooperating with each other in the various parts of the device, when the device is in use, the electric fan 46 blows the wind outside the elevator car 10 to the inside, the filter 32 filters the blown wind, and blows it to the inside of the elevator car 10 through the vent, so as to achieve the purpose of ventilation and air exchange inside the elevator car 10 and improve comfort. In winter, the positioning block 45 is squeezed outward, the positioning block 45 squeezes the elastic member 44 to shrink, the baffle 43 is manually rotated and the vent is blocked, the reaction force of the elastic member 44 squeezes the positioning block 45, the positioning block 45 fits on the surface of the baffle 43 and limits it, and is threadedly connected to the inner side of the threaded hole 60 through the threaded rod 48, thereby increasing the stability of the baffle 43, so that it will not blow directly on the human body surface, avoiding the phenomenon of people being cold due to wind blowing during ventilation in winter. At the same time, the number of vents can be adjusted according to usage needs, which greatly increases the applicability of the device.
