Because the setting of flexible block, the inwall of paddle and cartridge have big gap, thereby the manufacturing accuracy of puddle support and cartridge can reduce, thereby production cost is lower.In addition since flexible block be arranged on the paddle that radially extends along turning axle; The length that flexible block radially extends along turning axle need not very long; Thereby less elastic force can make flexible block contact with the inwall of cartridge; Friction force was less when it contacted and rotate with the cartridge inwall, and noise is little and energy consumption is little.
More concrete scheme is that the material of flexible block is a sponge.Flexible block adopts the less flexible material of elasticity, except that sponge, can also adopt other materials such as rubber.
Scheme is the downstream that flexible block is arranged on the paddle sense of rotation more specifically.The downstream that flexible block is arranged on the paddle sense of rotation makes the stirring resistance littler, thereby energy consumption is littler.
Further scheme is to state paddle to have to the crooked part in its sense of rotation downstream more specifically.Further reduce and stir resistance.
The length that the length that the part that another more concrete scheme is the relative meal outlet of flexible block is radially extended along turning axle is radially extended along turning axle greater than other parts.Length corresponding to the flexible block of meal outlet can make carbon dust discharge from meal outlet more reposefully than length.
