Embodiment approach
[0037] As an embodiment of the present invention, another communication passage 20 connecting the installation groove 19 and the inner cavity of the tank body 1 is provided in the inner wall of the tank body 1 below the installation groove 19, and the communication passages on both sides of the installation groove 19 20 are all provided with one-way valves 21 with the same flow direction. Through the setting of the one-way valve 21, the material can be sucked in through one communication channel 20 when the piston 7 is pulled out, and then the material can be discharged through another communication channel 20 when the piston 7 is compressed, thus realizing the forced circulation mixing between the upper and lower layers of materials , to avoid delamination that affects the overall stirring effect; at the same time, compared with the use of the water pump in the prior art, the application can realize the circulation of the material in the tank 1 only through the setting of the ...
