Description

Technical Field

[0001] The utility model relates to the technical field of ventilation structures, in particular to a module top plate ventilation structure for a rail train toilet. Background Art

[0002] As we all know, a rail train is a vehicle that runs on specific tracks and is typically used in public transportation systems. It is powered by electricity or diesel and travels along specially constructed tracks, providing efficient and stable transportation services. Rail trains include subways, light rail, and intercity railways. To enhance passenger comfort, rail trains are often equipped with multiple restrooms. These restrooms are designed with a strong emphasis on ventilation. Ventilation systems utilize a combination of natural and mechanical ventilation to ensure air circulation within the restrooms, maintaining a fresh and hygienic environment.

[0003] However, the traditional rail train toilet module ceiling ventilation structure usually uses fixed vents and ventilation ducts, which cannot dynamically adjust the ventilation volume according to usage needs. When some toilets have a strong odor, the odor may be retained in the toilet and cannot be discharged quickly and effectively. Therefore, technical improvements are urgently needed. Utility Model Content

[0004] The purpose of the present utility model is to solve the shortcomings existing in the prior art, and a rail train toilet module roof ventilation structure is proposed. When the rail train toilet module roof ventilation structure is used, the servo motor is started to drive the rotating column to rotate, and at the same time, the driving gear and the driven gear are driven to rotate, thereby driving the front end multiple rotating rods to rotate in the opposite direction, and the transmission wheel and the synchronous belt are used to drive the rear end multiple rotating rods to rotate, thereby driving the multiple opening and closing leaves to open and close. The air circulation rate can be effectively controlled by adjusting the spacing of the toilet opening and closing leaves. For toilets with larger odors, the spacing of the opening and closing leaves can be increased, and the spacing of the opening and closing leaves of some toilets can also be reduced to improve air flow and quickly discharge odors.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A roof ventilation structure for a rail train toilet module includes multiple roof panels and a mounting frame. The outer wall of one side of each roof panel is provided with a flow slot.

[0007] Ventilation slots are provided at the front and rear ends of both sides of the bottom surface of the mounting frame, a storage slot is provided in the middle of the upper surface of the mounting frame, and a plurality of rotating rods are rotatably connected to the front and rear ends of the inner wall of the storage slot, both sides of the rotating rods pass through the ventilation slot and are rotatably connected to the inner wall of the ventilation slot, opening and closing leaves are sleeved on both sides of the rotating rod body, a servo motor is fixedly connected to the middle of the inner wall of one side of the storage slot, and the output end of the servo motor is fixedly connected to the rotating column.

[0008] Through the above technical solution, compared with the existing rail train toilet module top plate ventilation structure, when the rail train toilet module top plate ventilation structure is used, the dust filter can be easily installed and disassembled through the elastic card block and the card slot, and the connection frame can be cleaned or replaced as needed.

[0015] Furthermore, the front ends of the outer wall of the rotating column and the rotating rod near the rear end of the rotating column are both sleeved with a transmission wheel 1, and the outer wall of the transmission wheel 1 is sleeved with a synchronous belt 1;

[0016] Through the above technical solution, a synchronous belt is provided through the outer wall of the transmission wheel, so as to drive the rear end rotating rod to rotate as the rotating column rotates.

[0021] Furthermore, the front end and the rear end of the upper surface of the mounting frame are fixedly connected to a mounting plate, and the upper surface of the mounting plate is provided with a plurality of mounting holes;
