Abstract: A cooling assembly and a heat-not-burn cartridge are provided. The cooling assembly includes a cooling member, a first closing member, and a second closing member. The cooling member has a first end and a second end opposite to the first end, and defines a cooling passage penetrating through the first end and the second end. The first closing member is fixed to the first end. The first closing member defines at least one first through-hole. The at least one first through-hole is in communication with the cooling passage. The second closing member is fixed to the second end. The second closing member defines at least one second through-hole. The at least one second through-hole is in communication with the cooling passage.

Abstract: A method for assembling a cartridge is provided. The method for assembling the cartridge includes the following. Multiple outer tubes are provided, where each of the multiple outer tubes has a sealing portion at a first end of a corresponding outer tube. Tobacco is loaded from a second end of the outer tube, where the second end is opposite to the first end. A closed end of a cooling tube is identified, and the cooling tube is mounted into the outer tube from the second end to make the closed end adjacent to the tobacco, where the cooling tube has the closed end and an open end opposite to the closed end. A filter member is mounted into the outer tube from the second end to make the filter member adjacent to the cooling tube.

Abstract: A filter assembly and a cartridge are provided. The filter assembly includes a filter member and a functional member. The filter member defines a receiving space in a radial direction of the filter member. The functional member is fixed in the receiving space. The filter member is in contact with part of an outer surface of the functional member.

Abstract: The present invention provides a method for improving tobacco-planting soil by using biochar, and belongs to the technical field of soil improvement. The method includes the following steps: (1) carbonizing agricultural and forestry waste to obtain biochar; (2) pulverizing the biochar to obtain a biochar particle; and (3) mixing the biochar particle with a plow layer of the tobacco-planting soil to obtain biochar-improved soil. Compared with tobacco-planting soil that is not added with the biochar (control), the method provided by the present invention greatly increases carbon and nitrogen contents of the tobacco-planting soil, and significantly increases moisture and available potassium contents of the tobacco-planting soil, which is beneficial to ensure the sorption of soil moisture and nutrients by the tobacco plant.

Abstract: A mechanism for releasably locking a drawer and preventing the drawer from inadvertently slipping out of its recess includes a user-accessible bar that actuates locking hooks to release the drawer from a locked position.

Abstract: This utility model relates to a type of multi-door interlocked tool box, consisting of box body and box door. Left and right side doors on the box body can be opened outward. Box door is of 2-leaf type. A rotor disc is provided on lower bottom plate. On rear board of the box, and inner surfaces of left and right side doors and the 2-leaf box door, hook plates that can accommodate many tools are provided. Connecting rod installation seat is provided on inner surface of each door at frame side near lower edge of the door, and on upper disc of the rotor disc assembly. Rigid connecting rod is fitted between corresponding connecting rod installation seats on each door and the upper disc. The upper disc can rotate freely about the installation axis, so that as hauled by rigid connecting rod, left/right side doors and front 2-leaf door are driven to open synchronously, and all tools will be shown or withdrawn in the box and locked. Use and management is easy and safe.
