Siphon pipe end part structure for steam-head roller

The invention discloses a siphon pipe end part structure for a steam-head roller, belongs to the mechanical field, and primarily relates to the siphon pipe end part structure for the steam-head roller. The structure is characterized in that a siphon pipe is provided with a protecting end part. Minimization and effectiveness of a siphon gap are guaranteed through the protecting end part by enlarging the siphon gap of the siphon pipe in terms of principles of couple hardness with softness and Yin and Yang assisting each other: the siphon pipe is easy to break if too rigid and the siphon pipe isnot rigid persistently, the siphon pipe is easy to bend if too flexible and the flexibility is not persisted, and it is bound to loss and Yin is lost to benefit Yang. Impact of the roller is absorbedand avoided by means of elastic deformation, flexible deformation and quick wear of the protecting end part, so that a technical problem in a dilemma that it is to guarantee the minimum siphon gap ofthe siphon pipe and it is t
