A coffee filtering device includes a filtering cup, a grinding device, and a base. The filtering cup includes a first peripheral wall and a first bottom wall. First lateral filtering nets are disposed in the first peripheral wall. The first bottom wall includes a longitudinal hole and first lower filtering nets. The grinding device includes a blade unit disposed in the filtering cup and a transmission shaft coupled with the blade unit to rotate therewith. The base is disposed around the filtering cup and includes a second bottom wall connected to a lower end of a second peripheral wall which is coupled with the first peripheral wall of the filtering cup. Second lateral filtering nets are disposed in the second peripheral wall. The second bottom wall includes a longitudinal hole and second lower filtering nets. The transmission shaft extends through the longitudinal holes of the first and second bottom walls.

A separation apparatus for separating an unwanted substance from an extraction target includes a forming unit configured to form a separation chamber through which the extraction target passes, and a suction unit communicating with the separation chamber in a direction crossing a passage direction of the extraction target and configured to suck air in the separation chamber. The forming unit includes an inlet for the extraction target, which communicates with the separation chamber, and an outlet for the extraction target, which communicates with the separation chamber, and the air is sucked from the outlet into the separation chamber by suction of the suction unit.

The present disclosure discloses a double-material grinder for grinding materials comprising a housing and a grinding component. The housing comprises a first housing and a second housing removably attached to each other to form a closed cavity. The first housing comprises a vertical baffle. The grinding component comprises a first grinding unit arranged in the first chamber and a second grinding unit arranged in the second chamber. A blanking gap of the first grinding unit corresponds to the first blanking hole. A blanking gap of the second grinding unit corresponds to the second blanking hole. The second housing comprises a driving unit to drive the first grinding unit and the second grinding unit. The mouth for adding materials is open and substantially larger than those of other two-material grinders so that replenishing of materials becomes easier and mixture of different materials is completely prevented.

A bean grinding machine includes a base seat, a bean container mounted on the base seat, and a grinding mechanism removably mounted on the base seat. The grinding mechanism includes first and second grinding members which are rotatable relative to and cooperate with each other to define a grinding space for receiving beans introduced from the bean container. Both the first and second grinding members can be removed from the base seat for facilitating cleaning.

An adhesive tape dispenser having a holder for an adhesive tape roll (2) and a guide system for an adhesive tape (3) pulled off from the adhesive tape roll (2) and a deflecting edge (10) for the pulled-off adhesive tape (3). Deflecting edge is arranged at the end of the guide system in the pull-off direction (A) and deflects the pulled-off adhesive tape (3) from the pull-off direction (A). The deflecting edge (10) has a deflection axis, which has a component directed in the pull-off direction (A), and an affixing direction (B) is arranged transversely to the pull-off direction (A).

A grinder for preparing brewing materials has a main casing, a grinding assembly and an unloading assembly to measure the amount of the brewing powder to unload. The unloading assembly has an unloading motor and a measuring barrel. When the user puts the brewing materials into the main casing, the grinding assembly grinds the brewing materials into the brewing powder. The brewing powder drops into the unloading assembly. When the unloading motor actuates the measuring barrel rotates, the brewing powder is deposited in a partafilter. Therefore, a user can grind tea leaves, Chinese herbal medicine, the petals and so on to have fresh brewing powder. Brewing liquids with the fresh brewing powder keeps the nutrient content and flavor. In addition, the bags for packaging the brewing powder is no longer needed to reduce environmental pollution and packaging cost.

A grinder comprises: a receiving container, formed with an accommodation space and an installation space, and the bottom end thereof being extended with a connection ring have a feeding port, and a hollow grinding seat and a fasten ring are respectively and detachably disposed in the feeding port and the connection ring; an electric driving device, detachably disposed in the installation space; and a base, detachably disposed at the bottom end of the receiving container and including a hollow grinding chamber having the interior disposed with a support member with a pivotal shaft, a passive rod is sleeved and linked with a conical grinding disk, the top end and the bottom end of the passive rod are respectively sleeved with the output shaft and the pivotal shaft, thereby allowing the grinding disk to protrude into the grinding seat and forming a gap between the above two.
