Description

Technical Field

[0001] The invention relates to a vibration-damping negative pressure box with an intelligent telescopic device. Background Art

[0002] Negative pressure means that the absolute pressure of the airflow is less than the absolute pressure at the same elevation outside the box, and its relative pressure is a negative value; the motor in the negative pressure box of the integrated stove drives the impeller in the volute to rotate at high speed, forming a negative pressure in the air inlet area, achieving the effect of inhaling oil smoke;

[0003] At present, the negative pressure box and volute of most integrated stoves are fixed with bolts. When the integrated stove is cleaned internally, it is inconvenient to disassemble and assemble the volute inside the negative pressure box due to the compact space and low position of the negative pressure box. The outer shell of the volute is fixed to a fixed position in the negative pressure box with a steel lifting lug. During operation, the high-speed rotation of the motor drives the volute to vibrate, and a layer of rubber gasket is usually added between the lifting lug and the fixed position to reduce vibration. However, this vibration reduction method does not achieve a good vibration reduction effect. Summary of the invention
