[0025] When the impact force of the water is large, the plurality of springs 7, the plurality of limiting plates 6 and the elastic hose 5 cannot completely absorb and offset the impact force, when the vertical cylinder 3 shakes, the shock-absorbing mechanism can buffer the vertical cylinder 3, so that the vertical cylinder 3 can quickly and stably land, at the same time, since the water inlet pipeline 11, the water outlet pipeline 12 and the two connecting pipelines 14 are telescopic hose structures, during the shaking of the vertical cylinder 3, the water inlet pipeline 11, the water outlet pipeline 12 and the two connecting pipelines 14 can twist along with the shaking of the vertical cylinder 3, preventing the shaking of the vertical cylinder 3 from being transmitted to the external pipeline and the electric boiler body 2, and further protecting the external pipeline and the electric boiler body 2.

[0026] As a technical optimization scheme of the utility model, the shock-absorbing mechanism comprises a first hinge base 8 fixedly connected to the outer wall of the vertical cylinder 3, and the front end face of the mounting plate 1 is fixedly connected with two second hinge bases 9 distributed left and right, and the two second hinge bases 9 and the first hinge base 8 are movably connected with shock-absorbing damping rods 10.

[0027] In the embodiment, when the vertical cylinder 3 shakes, the vertical cylinder 3 buffers the vertical cylinder 3 with the plurality of shock-absorbing damping rods 10, so that the vertical cylinder 3 can quickly and stably land.

[0028] As a technical optimization scheme of the utility model, the upper end face of the electric boiler body 2 is communicated with a water inlet pipeline 11 and a water outlet pipeline 12 distributed left and right, and the other ends of the water inlet pipeline 11 and the water outlet pipeline 12 are respectively communicated with the two through holes 4 located below.

[0030] As a technical optimization scheme of the utility model, electromagnetic valves 13 are installed inside the through hole 4 located below the left side and the through hole 4 located above the right side.

[0031] In the embodiment, the electromagnetic valves 13 can control the water entering and exiting the electric boiler body 2.

[0032] As a technical optimization scheme of the utility model, the upper end surface of the vertical cylinder 3 is fixedly connected with a connecting pipeline 14 in communication with the upper through hole 4, and the other end of the connecting pipeline 14 is in communication with a fixed flange 15.

[0039] When the two electromagnetic valves 13 are closed, water impacts the two electromagnetic valves 13 by inertia, at this time, the elastic hose 5 is stretched out by the impact force, at the same time, the elastic hose 5 pushes the plurality of limiting plates 6 to move outward, so that the impact force of the water is released, then the plurality of springs 7 push the plurality of limiting plates 6 to reset, at the same time, the elastic hose 5 shrinks to the original shape, thereby absorbing and canceling the impact force of the water, preventing the vertical cylinder 3 and the electric boiler body 2 from shaking, and avoiding affecting the external pipeline and the electric boiler body 2.
