The utility model discloses a biomass combustion boiler, which relates to the technical field of agricultural machinery and comprises a boiler body, and a bag breaking chamber and a hearth are arranged in the boiler body. A plurality of horizontally-arranged branch pipes are arranged in the bag breaking chamber and arranged around straw bags, the ends of the branch pipes are fixed to a main pipe, the main pipe penetrates through the bag breaking chamber and extends outwards, the extending end of the main pipe is provided with a connector, the connector is connected with a hearth or a heat exchanger, and the heat exchanger is connected with the hearth. By means of the arrangement, the main pipe discharges smoke generated by materials in the hearth to the surfaces of straw bags through the branch pipes; smoke contains gas components such as carbon dioxide and nitrogen which do not support combustion, and when the smoke surrounds the straw bags, air (oxygen) can be isolated to a certain degree, so that combustion of the straw bags is inhibited, and the flame-retardant effect is achieved.

The application provides a smoking set, which comprises a heating cylinder, a heating cavity extending upward and having an opening for inserting a cigarette, the heating cylinder having a first through hole area and a second through hole area, the first through hole area being farther from the bottom of the heating cylinder than the second through hole area, the first through hole area being provided with at least one first overheating hole, and the second through hole area being provided with at least one second overheating hole; a heat conducting member sleeved on the heating cylinder; a combustion cavity below the heating cylinder; a feeding structure for feeding combustible medium to the combustion cavity; an igniter for igniting the combustible medium in the combustion cavity; the combustion cavity, the heat conducting member, the first overheating hole or the second overheating hole, and the heating cavity sequentially communicating to form an airflow circulation channel; and the airflow entering the heating cavity through the first overheating hole is greater than the airflow entering the heating cavity through the second overheating hole per unit time. The cigarette provided by the application can realize rapid and uniform heating of the cigarette in the heating cavity.

The utility model discloses a moxa -moxibustion cupping apparatus, including cupping body, it is the hollow cavity of two ends opening, set up in the flow guide sleeve of cupping body, the protection cylinder is through the flow guide sleeve and is set up in cupping body, detachable setting on the outer lid body of cupping body, the multiple air inlets are set up on it and pass through, the adjusting inner lid subassembly includes the adjusting piece and knob of setting respectively on the opposite two sides of outer lid body, and the adjusting piece is fixedly connected with knob through fixed screw, and fixed screw movable passes through outer lid body, adjusting piece is provided with a plurality of stoppers, and the gap is provided between two adjacent stoppers, stopper can respectively to a plurality of air inlets carry out the shading operation. The utility model discloses through cupping body, flow guide sleeve, protection cylinder, outer lid body and the cooperation of adjusting inner lid subassembly, has effectively solved the problem that the slow burning speed of current moxa -moxibustion cupping apparatus reaches the moxa -moxibustion temperature.
