2results about How to "Increase the extension length" patented technology

The utility model discloses a kind of heating device and cleaning equipment with it, wherein heating device provides high-temperature water liquid and steam for cleaning assembly in cleaning equipment, and heating device includes shell and heating element, shell has cavity, and heating element is arranged in cavity with multiple segments bending.This utility model, heating element is arranged in cavity with multiple segments bending, can substantially extend the extension length of heating element in cavity without increasing the overall volume of heating device, without additionally promoting the power of heating element, to increase its contact with water liquid and the heat exchange area of medium, while breaking the one-way flow trend of medium, prompting it to form turbulence or circular flow, make medium and heating element contact more fully uniform, not only significantly speed up medium temperature rising speed, effectively shorten the waiting time of cleaning equipment initial high-temperature water liquid or steam, but also can reduce water drop in steam, improve cleaning effect.

The utility model provides a kind of anti-splashing device, including rack, gravure roll, two shaft sleeves and the splash guard plate respectively fixed in two shaft sleeves;Gravure roll includes roller body and the roller shaft fixed in the opposite ends of roller body, splash guard plate includes the first arc plate part that can be detached and fixed in the side of shaft sleeve away from roller body and is perpendicular to the axis of shaft sleeve Setting, second arc plate part and the arc-shaped slot formed by the recess of the side of second arc plate part away from first arc plate part;The outer circumferential side of roller body and second arc plate part are spaced from roller body, and the orthographic projection part of second arc plate part along perpendicular to the axis of roller shaft towards roller body falls on roller body;First arc plate part is spaced from rack, and arc-shaped slot penetrates second arc plate part along the circumference of second arc plate part.The anti-splashing device of the utility model can reduce the splashing of coating liquid at roller shaft, reduce the pollution of equipment, and facilitate the cleaning, replacement and other maintenance operations of splash guard plate.
