Description

Technical Field

[0001] The utility model relates to the technical field of folding rooms, in particular to a ventilation structure of a folding room. Background Art

[0002] A folding house is a mobile residential structure that can be folded or unfolded. This type of house is usually made of a series of foldable panels or materials, so that it can be unfolded into a house when needed, and folded up for easy carrying or storage when not needed.

[0003] Although existing folding houses are equipped with windows for ventilation, when residents choose to cook in the folding houses, oil smoke and hot air will be generated. Relying on the natural drift of oil smoke and hot air, it may not be quickly discharged from the windows of the folding houses, which will affect the living environment and health of residents; at the same time, in hot and humid weather, ventilation only through the windows of the folding houses will have poor ventilation effects, affecting the living experience of residents. To this end, we propose a ventilation structure for folding houses. Utility Model Content

[0024] See also Figure 4 In the figure, the elastic component includes a connecting ring 12, which is fixedly mounted on the outer wall of the plug post 14, and one end of the connecting ring 12 is attached to an inner side surface of the U-shaped shell 11, and a spring 13 is fixedly connected between the other end of the connecting ring 12 and the other inner side surface of the U-shaped shell 11, and the spring 13 is located on the outer side of the plug post 14.

[0025] See also Figure 4In the figure, the longitudinal sections of the two pulling posts 6 are both I-shaped; the I-shaped pulling posts 6 can be pulled more conveniently.

[0026] In this embodiment, the exhaust fan 17 is connected to an external power supply, so that the exhaust fan 17 can blow out the air in the room 1, and the outside air can be sucked into the room 1. When the residents choose to cook in the room 1, the generated fumes and hot air can be quickly discharged from the room 1 by the exhaust fan 17, so as to avoid affecting the living environment and health of the residents. At the same time, in hot and humid weather, the exhaust fan 17 can also improve the air flow in the room 1, thereby improving the ventilation effect and improving the living experience of the residents.

[0027] The arrangement of the filter 5 prevents flying insects from entering the room 1 along the circular ring 3 and affecting the occupants when the exhaust fan 17 is not in use and the doors and windows are closed at night. At the same time, when the filter 5 is gradually blocked after long-term use, in order to ensure the ventilation rate of the room 1 when the exhaust fan 17 is started, the occupants go to the corresponding filter 5 outside the room 1 and climb up with the help of a bench. Then, they can hold the two pull columns 6 with both hands and move them close to each other. The pull columns 6 can drive the plug column 14 to slide outward in the inner wall of the U-shaped shell 11, and the plug column 14 will drive the connecting ring 12 to squeeze the spring 13 connected to the inner wall of the U-shaped shell 11, until the plug column 14 leaves the socket 20 in the circular ring 3, the ring 4 and the filter 5 can be taken out together in the circular ring 3. On the contrary, the ring 4 and the filter 5 can be installed together in the circular ring 3. The filter 5 is easy to disassemble and assemble, thereby facilitating the cleaning and maintenance of the filter 5.

[0028] Example 2

[0029] See also Figure 2 , Figure 3 and Figure 5 The present embodiment further explains Example 1. In the figure, the shielding assembly includes a covering plate 2 and a slot 7. The covering plate 2 is rotatably arranged at the front end of the ring 3 through a rotating mechanism. The slot 7 is arranged at the front end of the ring 3 away from the covering plate 2, and a screw hole 21 is arranged on the inner wall of the slot 7. A U-shaped block 18 is fixedly connected to the outer wall of the covering plate 2 away from the ring 3, and a bolt 19 is penetrated and tightened on the inner wall of the U-shaped block 18.

[0030] See also Figure 3 In the figure, the rotating mechanism includes a groove 8, which is opened at the front end of the ring 3, and a cylinder 9 is rotatably connected between the upper and lower ends of the inner side of the groove 8. A U-shaped block 10 is fixedly sleeved in the middle of the outer wall of the cylinder 9, and one end of the U-shaped block 10 is fixedly connected to the outer wall of the cover plate 2.

[0031] In this embodiment, when it rains, the covering plate 2 is rotated so that the U-shaped block 18 on the outer wall of the covering plate 2 fits into the groove 7 of the circular ring 3. During the process, the covering plate 2 can drive the U-shaped block 10 to rotate, and the U-shaped block 10 can drive the cylinder 9 to rotate in the inner wall of the groove 8. Then, the bolt 19 is rotated to screw it into the screw hole 21 in the groove 7 to fix the covering plate 2. At this time, the covering plate 2 can seal the circular ring 3 to prevent rainwater from entering the room body 1 along the circular ring 3.

[0032] Example 3

[0033] See also Figure 4 This embodiment further explains Example 1. In the figure, the upper and lower parts of the inner wall of the circular ring 3 are fixedly connected with positioning plates 16. The two positioning plates 16 are located between the sleeve ring 4 and the exhaust fan 17. The front ends of the two positioning plates 16 are attached to the rear end of the sleeve ring 4. The front ends of the two positioning plates 16 are fixedly connected with positioning columns 15. The two positioning columns 15 are movable and penetrate the front end of the sleeve ring 4.
