Technical Field
[0001] This application relates to the field of oven technology, and in particular to an up-and-down adjustment mechanism for the static pressure chamber of an oven. Background Technology
[0002] A static pressure chamber, also known as a static pressure box, is a device that converts the kinetic energy of airflow into static energy. Its principle is to introduce airflow into a sealed cavity, causing the airflow to slow down within the cavity, thus converting kinetic energy into static energy. Inside the static pressure chamber, the airflow velocity decreases, and the airflow pressure increases, thereby creating static pressure. Therefore, in the use of an oven, a pipe connection to the static pressure chamber is required to ensure stable airflow inside.
[0003] However, existing static pressure chambers can only be fixed with bolts during installation, making secondary adjustments inconvenient. As a result, it is difficult to adjust the connection to meet the requirements of the airflow duct during use, reducing the ease of use of the static pressure chamber. Therefore, in order to correct the above defects, we propose an up-and-down adjustment mechanism for the static pressure chamber of an oven. Summary of the Invention
