Description

CROSS-REFERENCE TO RELATED APPLICATIONS The present application is a U. S. continuation of co-pending International Patent Application No. PCT/CN2022/104886 filed Jul. 11, 2022, which claims foreign priority of Chinese Patent Application No. 202210666501.8, filed on Jun. 14, 2022 in the State Intellectual Properly Office of China, the contents of all of which are hereby incorporated by reference. TECHNICAL FIELD The present invention relates to the technical field of bean grinders, in particular to a powder discharge outlet and a bean grinder equipped with the powder discharge outlet. BACKGROUND Existing bean grinders are generally equipped with a powder outlet integrated with or fixed on their housing. The powder outlet is located on the lower side of the cutter head. With the rotation of the cutter head, ground powder is discharged through the powder outlet. However, powder (especially ground coffee with high value) is accumulated on the inner wall of the pipe in the powder outlet due to electrostatic adsorption, which would cause waste. What's more, powder accumulated in the powder outlet for a long time would be deteriorated, breeding bacteria and affecting edible quality. In order to solve the problem of powder accumulation in the powder outlet, in traditional way, users generally flick or tap the powder outlet after grinding powder to vibrate the powder outlet and shake residual powder out of the powder outlet. However, as the powder outlet is integrated with the bean grinder housing, it is vibrated with a small amplitude, and powder cannot be completely shaken out of the powder outlet. The operation needs to be performed for many times before cleaning residual powder, which is inconvenient to use. SUMMARY The present invention aims to solve the problem existing in the prior art, and provides a powder discharge outlet and a bean grinder using the powder discharge outlet.
