Abstract

The invention discloses a dust recovery cover for tea processing, and relates to the technical field of range hoods. The dust recovery cover for tea processing comprises a top cover plate and a firstouter-packaging ring, and a first smoke inlet pipe is fixedly connected to the inner surface of the top cover plate; a first net cover is fixedly connected to the other end of the first smoke inlet pipe; a circular pipe is fixedly connected to the inner surface of the first smoke inlet pipe; a second smoke inlet pipe is matched to the inner surface of the circular pipe; a second net cover is fixedly connected to the other end of the second smoke inlet pipe; an outer decorative cover is fixedly connected to the outer surface of the top cover plate; a plurality of sliding grooves are formed in the inner surface of the first outer-packaging ring; and a second outer-packaging ring is slidably connected to the inner surface of the first outer-packaging ring through the sliding grooves. According to the dust recovery cover for tea processing, through the mutual coordination between the inner surface of the first outer-packaging ring and the outer surface of the second outer-packaging ring and the sliding up and down of the second smoke inlet pipe, the problems that the height of an existing range hood is relatively high from a stove, and the smoking effect of the range hood is not obvious during working are solved.

Description

technical field [0001] The invention belongs to the field of dust collection, in particular to a dust recovery cover for tea making. Background technique [0002] The height of the existing dust recovery hood is fixed, and at the same time, the opening size of the recovery hood is also fixed. When the dust density is high, the absorption capacity of the recovery hood is limited, resulting in dust escape, affecting the workshop environment, and polluting the environment at the same time. For this reason, a new dust recovery cover is now proposed. Contents of the invention [0003] The purpose of the present invention is to provide a dust recovery cover for tea making, through the mutual cooperation between the inner surface of the first outer wrapping ring and the outer surface of the second outer wrapping ring and the second smoke inlet pipe can slide up and down, which solves the problem that the height of the recovery cover cannot be adjusted Problem: Four expansion pla...
