Referring to fig. 1-2, an electric kettle cover comprises a kettle cover body 1, wherein a plurality of heat exchange ports 7 are formed in the outer side wall of the kettle cover body 1, a heat conduction plate 2 is fixedly connected to the inner side wall of the kettle cover body 1, a cavity is formed in the heat conduction plate 2, a rotating plate 4 is arranged in the cavity, a plurality of guide blocks 5 which are obliquely arranged are arranged at the bottom of the rotating plate 4 in a surrounding manner, and a plurality of air inlets 6 which are obliquely arranged and correspond to the guide blocks 5 are formed in the inner bottom of the cavity;

it should be noted that: wherein the air inlet 6 and the guide block 5 are inclined in opposite directions, so that the air flow from the air inlet 6 upwards pushes the rotating plate 4 to rotate through the guide block 5, thereby realizing the process of accumulating the force of the rotating plate 4.

Wherein, the bottom of the rotating plate 4 is fixedly connected with a fixed shaft 8, and the bottom of the fixed shaft 8 penetrates through the inner bottom of the cavity and is fixedly connected with a plurality of fan blades 9;

it should be noted that: the interior bottom of cavity is seted up and is run through the mouth that corresponds with fixed axle 8, runs through the inside wall fixedly connected with sealing layer of mouth, guarantees the leakproofness when fixed axle 8 and heat-conducting plate 2 rotate like this, and then prevents that ascending air current from passing through fixed axle 8 and running through the space between the mouth and entering into in the cavity.

The top of the rotating plate 4 is fixedly connected with a control shaft 10, the top of the control shaft 10 sequentially penetrates through the inner top of the cavity and the kettle cover body 1 and is fixedly connected with a control block 11, the top of the kettle cover body 1 is fixedly connected with a sealing ring 12, the control shaft 10 is rotatably connected with the inner side wall of the sealing ring 12, the top of the heat conducting plate 2 is fixedly connected with a connecting ring 13, the control shaft 10 is positioned in the connecting ring 13, and the outer side wall of the control shaft 10 is fixedly connected with the inner side wall of the connecting ring 13 through a clockwork spring 3;

it should be noted that: wherein constantly store kinetic energy after taking place deformation through clockwork spring 3 to, realize the rotation of rotor plate 4 after the later energy release, in addition, at the inside wall fixed connection rubber sealing layer of sealing ring 12, guarantee like this that the heat in the kettle lid 1 can not outwards spill over, guarantee the leakproofness in the kettle lid 1 promptly.

The using process of the invention is as follows:

when the kettle is used, the kettle cover body 1 is covered on the electric kettle, wherein attention needs to be paid that the heat exchange port 7 is sealed with the inner side wall of the water inlet of the electric kettle, namely the heat exchange port 7 is positioned in the water inlet of the electric kettle, when the electric kettle heats water, the water can continuously generate hot steam, the hot steam can move upwards, the upward moving hot steam can be upwards sprayed out through the air inlet 6, the inclined direction of the air inlet 6 is opposite to the inclined direction of the guide block 5, so that the guide block 5 is driven to slowly rotate under the action of the steam, the rotating plate 4 is further driven to rotate, the rotating plate 4 can drive the control shaft 10 at the top of the rotating plate 4 to rotate, the rotating of the control shaft 10 can enable the clockwork spring 3 to continuously obtain elastic potential energy through rotation, the process of the clockwork spring 3 for storing force is realized, wherein, although the kinetic energy of the clockwork spring 3 is larger and larger when the clockwork force is stored, however, as the temperature of the water is higher and higher, the amount of the hot steam is larger and larger, so that the rotation of the rotating plate 4 is continuously pushed.

When water is poured, a hand can hold the handrail on the electric kettle, meanwhile, the control block 11 is pressed by a thumb, the rotation of the control block 11 is prevented, namely, after the water in the electric kettle is poured out, the hot steam is reduced, the clockwork spring 3 is prevented from releasing elastic potential energy at this time by pressing the control block 11, after the water in the electric kettle is poured out, the kettle cover body 1 is lifted upwards slightly, so that the heat exchange port 7 is just separated from the water inlet of the electric kettle, but the kettle cover body 1 is not separated, the outside air is contacted with the heat conduction plate 2 through the heat exchange port 7, so as to cool the heat conduction plate 2, the hot steam entering from the air inlet 6 is cooled when encountering the cooled heat conduction plate 2, so that the rotation of the rotating plate 4 is not driven, at this time, the control block 11 is loosened, the clockwork spring 3 can instantly release the elastic potential energy, the clockwork spring control shaft 10 is rotated under the action of the work spring 3, so as to drive the rotation of the rotating plate 4, and then the rotating plate 4 drives the fan blades 9 to rotate through the fixed shaft 8, the rotation of the fan blades 9 can generate downward air flow, the downward air flow can enable hot steam in the electric kettle to be sprayed out from a spout of the electric kettle, and then the hot steam in the electric kettle can not be sprayed out upwards to scald people after the kettle cover body 1 is opened.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
