The working principle of the pressing member 63 here is similar to that of a watering can. The pressing member 63 is composed of a pressing part and a spring pump, so that it is reset by the action of the elastic force of the spring pump. The pressing member 63 is used to control the bubble removal liquid in the liquid storage tank 62 to be sprayed through the spray rod 65. The inner wall of the mixing barrel main body 2 is fixedly connected with an arc block 66, which compresses the pressing member 63.

[0025] The arc block 66 is on the motion track of the pressing member 63. The pressing member 63 is reset by the elastic force of its own spring pump to squeeze the liquid storage tank 62. A gap is set between the pressing member 63 and the liquid storage tank 62.

[0026] The spray rod 65 is below the stirring paddle 5, and a gap is provided between the liquid storage tank 62 and the stirring barrel body 2;

[0027] The pressing member 63 is pressed against the inner wall of the mixing barrel 2 and the pressing member 63 is pressed against the outer wall of the mixing barrel 2. The pressing member 63 is pressed against the inner wall of the mixing barrel 2 and the pressing member 63 is pressed against the outer wall of the mixing barrel 2.
