They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0019] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.
[0020] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:

The subsequent raw materials are placed in the cavity inside the cover shell through the feed pipe, and the first switch valve is closed after the raw materials are placed to cut off the connection between the feed pipe and the cavity, so as to avoid the problem that when the cavity is connected to the inner cavity of the kettle body, the raw materials will be sprayed out of the feed pipe due to the pressure in the inner cavity of the kettle body; at this time, the cover shell is driven to rotate by the driving component, so that the cavity inside the cover shell rotates to connect with the first feed port of the kettle body, and the raw materials in the cavity are mixed with the solution in the kettle body, so as to realize feeding to the bottom side of the kettle body, and then through the feeding method from the bottom side of the kettle body, the subsequent raw materials can directly enter the bottom of the kettle body, so that the subsequent raw materials are fully mixed with the previous raw materials that have sunk to the lower part of the kettle body, and stirred evenly, so as to effectively ensure the product quality;
[0023] And the bottom feeding of subsequent raw materials such as powder, granules or solution can be met by the cooperation between the feeding pipe and the cavity.
[0024] Further, the driving member 10 includes a cylinder 11 disposed on one side of the kettle body 1, a first connecting seat 12 is connected to the driving shaft of the cylinder 11, a guide shaft 13 is disposed on the first connecting seat 12, a second connecting seat 14 is connected to one side of the cover shell 5, a guide groove 15 is provided on the second connecting seat 14 along its length direction, and the guide shaft 13 is movably disposed in the guide groove 15. Specifically, the first connecting seat is driven to move telescopically by the cylinder, so that the guide shaft on the first connecting seat moves along the guide groove of the second connecting seat, and then the cover shell is driven to reciprocate relative to the kettle body, so as to realize the mutual connection and docking or disconnection between the first feed port of the kettle body and the housing cavity of the cover shell.
[0025] Furthermore, a first reflux pipe 16 connected to the cavity 7 is provided on one side of the cover shell 5, and a second reflux pipe 17 is provided on the kettle body 1. The first reflux pipe 16 and the second reflux pipe 17 are connected by a hose, and a liquid pump (not shown) is provided on the first reflux pipe 16 or the second reflux pipe 17. Specifically, when the cover shell and the kettle body rotate relative to each other so that the cavity of the cover shell and the first feed port of the kettle body are not connected to each other, the cavity will be loaded with a solution, and then the solution in the cavity will be pumped back into the kettle body through the cooperation between the liquid pump, the first reflux pipe, the second reflux pipe and the hose.
[0026] Furthermore, the first reflux pipe 16 is connected to a drain pipe 18, and a second switch valve (not shown) is provided on the drain pipe 18. Specifically, when the housing and the kettle body rotate relative to each other so that the housing cavity and the first feed port of the kettle body are disconnected, the cavity will be loaded with solution, and then the first reflux pipe and the drain pipe cooperate with the second switch valve to facilitate sampling and testing of the mixed solution in the kettle body.

[0028] Furthermore, a third switch valve 20 is provided on the discharge pipe 6. The third switch valve is used to control the opening and closing of the discharge pipe.
[0029] Furthermore, the upper end of the kettle body 1 is provided with a second feed port 21, and the kettle body 1 is provided with a cover plate 22 capable of sealing and covering the second feed port 21. Furthermore, by providing the second feed port at the upper end of the kettle body, the preceding raw material can directly enter the kettle body from the second feed port, and the succeeding raw material can enter the kettle body from the feed pipe through the cavity through the first feed port.
[0030] Furthermore, a plurality of sealing rings (not shown) are arranged along the circumference between the cover shell 5 and the kettle body 1. The sealing performance between the cover shell and the kettle body when they rotate relative to each other is enhanced by the plurality of sealing rings matched along the circumference.
