Problems solved by technology

However, due to the heavy weight of the oven exhaust fan, it will crush the top of the oven, and because the oven exhaust fan is installed on the top of the oven through the installation bolts, after a long period of use, the installation bolts will be loose due to the vibration of the oven exhaust fan. The bottom of the oven exhaust fan collides with the top of the oven, which creates a lot of noise and affects the quality of the working environment

Abstract

The invention discloses an oven exhaust fan, which comprises an exhaust fan base, wherein an elastic cushion is arranged below the exhaust fan base through a mounting bolt; the lower surface of the exhaust fan base is provided with a plurality of protruding cylinders; grooves matched with the cylinders are formed on the upper surface of the elastic cushion; and elastic parts are arranged between the small surfaces of the cylinders and the lower surfaces of the grooves. By the oven exhaust fan, the top of an oven is prevented from being crushed when the oven exhaust fan is arranged on the top of the oven, when the oven exhaust fan is used for a long time, the mounting bolt is loosened due to vibration of the oven exhaust fan, after the mounting bolt is loosened, and the bottom of the oven exhaust fan collides with the elastic cushion only, so that the running noise is greatly reduced, and the quality of a working environment is improved; and moreover, after the mounting bolt is loosened, the cylinders act on the elastic parts, and a buffering function is realized, so that relative motion between the exhaust fan base and the elastic cushion is reduced, the service life of the elastic cushion is prolonged, the maintenance cycle is long, and the efficiency of the oven exhaust fan is improved.

Description

technical field [0001] The invention relates to an exhaust fan, in particular to an oven exhaust fan. Background technique [0002] An oven is a device that heats an electric heating device through a power supply to dry objects. The oven exhaust fan is used to exhaust the moisture and smoke inside the oven to the outside. In order to save space, the oven exhaust fan is often installed on the top of the oven. However, due to the heavy weight of the oven exhaust fan, it will crush the top of the oven, and because the oven exhaust fan is installed on the top of the oven through the installation bolts, after a long period of use, the installation bolts will be loose due to the vibration of the oven exhaust fan. The bottom of the oven exhaust fan collides with the top of the oven, which creates a lot of noise and affects the quality of the working environment. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present inve...
