Description

Technical Field

[0001] This utility model relates to the field of combustion testing technology, and in particular to a combustion testing machine. Background Technology

[0002] In daily life, various electronic products used by users often malfunction due to the complexity of the usage environment or improper use, thus creating fire hazards. Therefore, electronic products are usually tested for flame retardancy before leaving the factory.

[0003] Existing combustion testing equipment has certain drawbacks. First, because combustion produces smoke and dust, existing combustion equipment cannot collect the dust, which then disperses into the air and causes pollution. Second, existing combustion equipment lacks protective mechanisms, resulting in insufficient safety and thus having a certain impact. Therefore, a combustion testing machine is urgently needed to solve these problems. Utility Model Content

[0004] To solve the above problems, this utility model provides a combustion testing machine, which is achieved through the following technical solution.

[0005] A combustion testing machine includes a test platform. A combustion cylinder is fixedly connected to the top of the test platform. A protective cover is installed above the combustion cylinder. A water tank, a water pump, and an igniter are fixedly connected to the top of the protective cover. A spray head is fixedly connected to the output end of the water pump. An ignition gun is installed on the igniter. A smoke exhaust port is opened on the combustion cylinder. A dustproof net is fixedly connected inside the smoke exhaust port. A column is fixedly connected to the top of the test platform. A movable seat is movably connected to the column. A servo motor is fixedly connected to one end of the column. A lead screw is fixedly connected to the output shaft of the servo motor. An air intake pump is fixedly connected to the bottom of the test platform. An air intake pipe is fixedly connected to the air intake end of the air intake pump. A connecting pipe is connected through the air intake pipe. A fuel tank is installed inside the combustion cylinder. A storage rack is installed inside the fuel tank.

[0006] Furthermore, the input end of the water pump is connected to the water tank.

[0007] Furthermore, one end of the ignition gun extends above the fuel tank.

[0008] Furthermore, one end of the movable seat is fixedly connected to the protective cover, and the lead screw is threadedly engaged with the movable seat.

[0009] Furthermore, handles are fixedly connected to both ends of the top of the fuel tank.

[0010] Furthermore, the connecting pipe passes through the experimental platform and connects to the smoke exhaust port.

[0011] Furthermore, the bottom of the experimental platform is provided with an air inlet, which is connected to the combustion chamber.

[0012] The beneficial effects of this invention are that, during operation, the air pump draws air into the connected protective cover through the air intake pipe and connecting pipe, while external air enters the combustion cylinder through the air inlet to supply oxygen, thus facilitating the complete combustion of the combustible material. During the air intake process, the dust filter fixed inside the exhaust port filters the smoke and dust generated during combustion. Finally, the water pump installed on the protective cover draws water from the water tank and sprays it out through the spray nozzle, which increases the safety of the combustion experiment.
