[0016] Compared with the prior art, the present invention provides a steam generator structure with a descaling function, and has the following beneficial effects:

[0017] 1. For the steam generator structure with a descaling function, scale generated in water is adsorbed by multiple thin sheets with concave holes on the outer wall, so that the scale adsorbed on the heating column is reduced, the service life of the heating column can be improved, and the energy consumption of the equipment can be reduced;

[0018] 2. The steam generator structure with a descaling function drives multiple reciprocating lead screws to rotate through a driving motor. Multiple reciprocating sliders will drive multiple reciprocating rods to slide up and down reciprocally. Multiple reciprocating rods will drive multiple groups of thin plates to slide up and down in the steam tank, so that multiple groups of thin plates can contact hot water more fully, thereby improving the effect of the thin plates adsorbing scale.

[0019] 3. The steam generator structure with a descaling function.

[0020] 4. The steam generator structure with a descaling function. By closing the first valve and opening the second valve, the steam in the steam tank will be discharged from the sewage pipe at this time. The steam flowing in the cavity will cause the massive scale on the outer wall of the thin plate to break off and be discharged from the sewage pipe under the action of the flowing steam, thereby automatically cleaning the scale on the thin plate and making the cleaning more convenient.

[0021] 5. The steam generator structure with a descaling function. The telescopic device drives the elastic airbag to extend into the cavity. When the reciprocating rod slides up and down reciprocally, the elastic airbag will contract and reset intermittently, and the annular airbag will drive the descaling brush to intermittently poke the scale on the outer wall of the thin plate, thereby further improving the effect of scale cleaning.

[0045] Working principle: In the present invention, during the operation of the steam generator, the thin sheets 7 on the outer wall of the reciprocating rod 6 will be inserted into the hot water in the steam tank 1, and multiple thin sheets 7 with concave holes on the outer wall will adsorb the scale generated in the water, thereby reducing the scale adsorbed on the heating column 3, which can improve the service life of the heating column 3 and reduce the energy consumption of the equipment.

When the reciprocating rod 6 slides up and down reciprocally, the bump 22 on the outer wall of the reciprocating rod 6 will indirectly press the elastic airbag 21, and the elastic airbag 21 will indirectly contract and reset. When the elastic airbag 21 contracts, it will transport the internal gas to the annular airbag 18 through the connecting pipe 23, and the annular airbag 18 will expand, and then the descaling brush 19 will be pushed against the cavity 5. The descaling brush 19 will brush the thin sheet 7 sliding up and down, thereby improving the efficiency of cleaning the scale on the thin sheet 7. And the indirectly contracting elastic airbag 21 will cause the annular airbag 18 to expand indirectly, and the annular airbag 18 will drive the descaling brush 19 to indirectly poke the scale on the outer wall of the thin sheet 7, thereby further improving the effect of cleaning the scale.
