A crusher includes a blade assembly and a drive assembly. The blade assembly includes a first blade and a second blade. The drive assembly is respectively connected with the first blade and the second blade, and is configured to drive the first blade and the second blade to rotate. The first blade is configured to disperse and perform primary cutting of the materials. The second blade is configured to perform secondary cutting of the materials. The first blade makes the materials fully disperse, so that the second blade can fully cut the materials. In addition, the first blade initially cuts the materials, so that the formed fragments can achieve a better fertilization effect.

An energy-saving preparation system for a silicon-carbon anode material of a lithium battery includes a pulverizing box and a feed port. The feed port is formed in the top of the pulverizing box; a pulverizing roller is rotatably mounted inside the pulverizing box; the inner wall of the pulverizing box is symmetrically fixedly connected with mounting plates; fixed plates are symmetrically fixedly connected between the two mounting plates; the surfaces of the two mounting plates are fixedly connected with rotating devices; the two fixed plates are fixedly connected with the rotating devices; the rotating devices are slidably connected with the pulverizing roller; the upper parts of the two mounting plates are fixedly connected with transverse plates; the rotating devices and the transverse plates are rotatably installed.

A handheld comminutor—spray bottle assembly includes a bottle; a comminutor; and a sprayer assembly. The bottle has an externally threaded mouth. The comminutor includes a comminutor body, with an internally threaded rim, housing a power source and an electrically connected motor. Blades connected to the motor by a shaft extend from the comminutor body. The sprayer assembly includes a spray head attached to a spray bottle cap, a siphon straw and an elongated filter housing connected with a spray head inlet, with a filter on the housing. A filter housing cap secures the filter to the housing. The spray bottle cap has an internally threaded rim and a seal ring. The comminutor rim and the spray bottle cap rim alternately connect with the mouth of the bottle. The motor rotates the shaft and the blades. Biomatter and liquid comminuted in the bottle are dispensed using the spray head.

A cap for closing a container including a cap body for contacting an open end of the container and at least one connector mounted to an exterior of said cap body for coupling said cap body to the container. The at least one connector includes an engaging piece and a lever. An initial movement of said at least one connector causes said engaging piece to contact the container and a further movement of said at least one connector causes said engaging piece to affix said cap body to the container.

A food recycler includes a case, a control system within the case, and a set of user interface components that are usable to at least cause the control system to initiate a food recycling cycle. The food recycler also includes a motor within the case and a bucket that has a volumetric capacity between 2.51 and 10 liters. A filter system configured to accommodate air filters is also included in the case of the food recycler. To remove water from waste food items, the food recycler includes a drying component.

A food preparation appliance has a base, a blade member rotatable in a direction of rotation, and a container with a closed bottom, an open top and a tubular sidewall together defining an interior space of the container. The top of the container is configured for releasable connection with the base, with the blade member disposed within the interior space of the container. The sidewall has a rib projecting inward of the interior space of the container and extending lengthwise along at least a portion of the sidewall from the top of the container toward the bottom of the container. The rib has, in the direction of rotation of the blade member, a peak defined as the shortest transverse dimension measured from the center of the container to the sidewall at a respective height along the portion of the sidewall having the rib, the rib being asymmetric in transverse cross-section.
