[0026] In the present example, a feeding pipe 104 which penetrates through the water collecting cavity 200 and extends into the reaction cavity 201 is arranged on the kettle cover 101, and a water feeding pipe 105 which extends into the water collecting cavity 200 is also arranged on the kettle cover 101; a discharge pipe 103 is arranged at the bottom of the kettle body 100, and a heating rod 205 is also arranged at the bottom of the kettle body 100;

[0027] In actual use, the raw materials are added into the reaction cavity 201 through the feeding pipe 104, heated by the heating rod 205, and stirred by the stirring assembly, so that the raw materials and the heating rod 205 occur chemical reaction in the kettle body 100 to prepare the chemical solution; when the preparation of the chemical solution is completed, the chemical solution can be discharged from the reaction cavity 201 through the discharge pipe 103.

[0028] In actual use, cooling water is added into the water collecting cavity 200 through the water adding pipe 105, and the water collecting cavity 200 is connected with the water tank 112 through the flow channel, and the water tank 112 is connected with the water adding pipe 104. Figures 2-3 As shown in the figure, in this embodiment, the flow channel includes a first cavity 202 and a second cavity 203. The first cavity 202 is arranged axially along the rotating rod 300 in the rotating rod 300.

[0029] Therefore, after the preparation of the chemical solution is completed, the cooling water in the water collecting cavity 200 flows through the stirring assembly, so that the stirring assembly can exchange heat with the chemical solution in the reaction cavity 201, and the chemical solution in the reaction cavity 201 can be cooled and cooled down. At the same time, the rotation of the stirring assembly can make the chemical solution in the reaction cavity 201 be uniformly cooled and cooled down, so that it can be discharged through the discharge pipe 103.

[0030] The lower end of the kettle body 100 is provided with a plurality of supporting legs 102, which support the kettle body 100, so that the lower end of the kettle body 100 can be away from the ground, thereby facilitating the discharge of the discharge pipe 103 and the installation of the water tank 112 at the lower end of the kettle body 100.

[0031] Since the feeding pipe 104 is connected with the reaction cavity 201, in order to avoid the irritating gas in the reaction cavity 201 when the chemical solution with irritating smell is prepared, the irritating gas flows out of the reaction cavity 201 through the feeding pipe 104, which affects the health of the operator, in this embodiment, a pipe cover is arranged at the pipe opening position of the feeding pipe 104 through screw thread.
