Description

Technical Field

[0001] The utility model relates to the technical field of recreational vehicle equipment, in particular to a ventilation device for recreational vehicles. Background Art

[0002] RV is a fashionable vehicle introduced from abroad. The household facilities on the vehicle include: bedding, stoves, refrigerators, cabinets, sofas, dining tables and chairs, washing facilities, air conditioners, televisions, stereos and other furniture and electrical appliances. It can be divided into driving area, living area, bedroom area, sanitary area, kitchen area, etc. RV is a fashionable product that integrates "clothing, food, housing and transportation" and realizes "traveling in life and living in travel". When the RV is in use, a ventilation device is generally installed to maintain air circulation in the car.

[0003] The current ventilation device needs to have a dustproof structure replaced when used for a long time. Since the dustproof structure is bolted to the inside of the ventilation device by fastening bolts, the disassembly of the dustproof structure is cumbersome and takes a lot of time. At the same time, when ventilating on rainy days, the inside of the ventilation device cannot be protected, causing rainwater to fall in and affect the ventilation device, thereby reducing the service life of the ventilation device.

[0004] According to the publication number: CN217778293U, a lightweight ventilation device is provided. The utility model includes an inner shell and an outer shell. The outer shell is installed in the inner shell. A vent is provided on one side of the inner shell. A fan frame is installed in the vent, and a fan is installed in the fan frame. An air outlet shutter is provided on the other side of the inner shell. With the addition of a fan, the outgoing wind effect is strong. The air outlet shutter can prevent dust from directly entering the RV. The lightweight ventilation device of the utility model has a simple shape and is close to a square. Not only is the air outlet effect ideal, but a fan is also installed, and the outgoing wind effect is strong. The product itself is made of plastic material, which is not only lightweight and will not increase the load-bearing burden of the RV itself, but also has ultra-low energy consumption and low noise, and will not affect people. The baffle of the vent has a certain curvature, and dust cannot directly enter the RV.

[0005] According to the ventilation device introduced above, the dustproof structure needs to be replaced when used for a long time. Since the dustproof structure is bolted to the inside of the ventilation device by fastening bolts, the disassembly of the dustproof structure is cumbersome and takes a lot of time. At the same time, when ventilating on rainy days, the inside of the ventilation device cannot be protected, causing rainwater to fall in and affect the ventilation device, thereby reducing the service life of the ventilation device. Therefore, we need to propose a ventilation device for RVs. Utility Model Content
