Pig house with anti-fog backflow function
By installing slatted floors, shovels, and adjustable baffles in the pigsty, the direction of foul air flow is controlled and leakage is reduced, thus solving the problem of foul air backflow in the pigsty and improving the quality of the breeding environment and the health of the pig herd.

Abstract
This invention relates to the field of pig farming technology, specifically to a pigsty with a function to prevent the backflow of foul air. The pigsty includes a frame, a support plate with multiple slatted floor panels, and side panels on both sides of the frame. A working cavity is located at the bottom of the support plate, and a manure collection cavity is located at the bottom of each slatted floor panel. A main ventilation duct is installed inside the pigsty frame, and a ventilation connection mechanism for controlling the flow of gas into the manure collection cavity is located on one side of the main ventilation duct. This invention uses multiple rotatable adjustable blocks to block the holes in the slatted floor panels in batches, controlling the flow direction of foul air. By creating hollow channels inside the adjustable blocks and installing internal ventilation ducts, ventilation through these hollow channels prevents foul air from rising and spreading into the pig farm. This prevents harmful gases in the foul air from affecting the growth of pigs, thereby reducing the content of harmful gases in the pig farm and lowering the probability of disease in pigs.
