[0002] Cast iron pots are made by melting gray cast iron and casting it into molds. Composed of a high proportion of carbon and iron, cast iron pots possess excellent heat storage and distribution capabilities. This material allows them to transfer heat evenly and stably, maintaining a high temperature for a considerable period, making them ideal for long-term simmering, baking, or stir-frying. Cast iron pots are very durable, able to withstand high temperatures and heavy pressure, and are not easily deformed or cracked. With proper maintenance, a cast iron pot can last for many years or even decades. Because of its even heat distribution and ease of use for stewing, it remains widely used in many places. Restaurants in many areas use cast iron pots to stew food, especially meat, to preserve its rich flavor.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1:
[0023] Please see Figures 1 to 3 The cast iron pot in this embodiment is designed for safe venting and includes a pot body 1, a pot lid 2 on the upper side of the pot body 1, and a handle 3 fixedly connected to the top of the pot lid 2.
[0024] In this embodiment, the pot lid 2 is provided with an exhaust assembly, which includes a fixed cover 4 and a fixed cylinder 5. The fixed cylinder 5 is located on the upper side of the fixed cover 4 and is fixedly connected to the upper side of the pot lid 2. The fixed cover 4 is fixedly connected to the lower side of the pot lid 2. The bottom of the fixed cover 4 is provided with an air hole 6. The fixed cylinder 5 corresponds to the air hole 6. An exhaust port 7 is provided on the outer wall of the fixed cylinder 5. A connecting rod 8 is inserted into the inner side of the fixed cylinder 5. A connecting plate 10 is fixedly connected to the upper end of the connecting rod 8. An exhaust plate 9 is fixedly connected to the lower end of the connecting rod 8. The exhaust plate 9 is adapted to the inner wall of the fixed cylinder 5.
[0025] A slider 17 is fixedly connected to the outer wall of the connecting rod 8. The slider 17 is slidably connected to the inner wall of the fixed cylinder 5. A groove adapted to the slider 17 is opened on the inner wall of the fixed cylinder 5. A second spring 18 is sleeved on the outer wall of the connecting rod 8. The lower end of the second spring 18 abuts against the slider 17, and the upper end of the second spring 18 abuts against the inner wall of the fixed cylinder 5. The position of the connecting rod 8 can be elastically adjusted by using the second spring 18.
[0026] Example 2:
[0027] Please see Figures 1 to 2Based on Embodiment 1, an adjustment assembly is provided on the inner side of the fixed cover 4. The adjustment assembly includes a partition 11, which is fixedly connected to the inside of the fixed cover 4. A fixed rod 12 is fixedly connected between the partition 11 and the fixed cover 4. A movable sleeve 13 is sleeved on the outer wall of the fixed rod 12. An adjustment rod 15 is fixedly connected to the upper side of the movable sleeve 13. The adjustment rod 15 extends to the upper side of the pot lid 2. A strip-shaped opening adapted to the adjustment rod 15 is opened on the inner side of the pot lid 2. A baffle 16 is fixedly connected to the outer wall of the adjustment rod 15. The baffle 16 passes through the inner side of the partition 11 and is located on the lower side of the fixed cylinder 5.
[0028] A first spring 14 is sleeved on the outer wall of the fixed rod 12. One end of the first spring 14 abuts against the movable sleeve 13, and the other end of the first spring 14 abuts against the inner wall of the fixed cover 4. The first spring 14 facilitates the elastic adjustment of the position of the adjusting rod 15.
[0029] The working principle of the above embodiments is as follows:
[0030] In use, by pushing the adjusting rod 15, the movable sleeve 13 is moved, which in turn moves the baffle 16 away from the fixed cylinder 5. The high-temperature gas inside the pot body 1 enters the fixed cover 4 through the air hole 6 and then enters the fixed cylinder 5. At the same time, the exhaust plate 9 inside the fixed cylinder 5 is moved, which in turn moves the connecting rod 8, so that the exhaust plate 9 moves upward away from the exhaust port 7, which facilitates exhaust. The adjusting rod 15 is located on the other side of the fixed cylinder 5 away from the exhaust port 7, so it is not easy to be burned by the high-temperature gas, thus improving the safety of use.
