Description

Technical Field

[0001] The utility model relates to the technical field of smoke generating devices, and in particular mainly to an automatic smoke generator. Background Art

[0002] According to the requirements of GB / T 18801-2015, when conducting the CCM test of the particulate matter of the air purifier, it is necessary to use the smoke generated by cigarettes as the standard pollution source, and evaluate the air purifier based on its purification ability of cigarette smoke. With the development of filter technology, the CCM value of particulate matter is getting higher and higher, resulting in the burning of hundreds of cigarettes in the whole process from the beginning to the end of the test to meet the test requirements.

[0003] However, the current generation of cigarette smoke mainly relies on manual methods, where the inspector manually lights the cigarette and manually puts the lit cigarette into the sealed combustion chamber. Therefore, manually placing and lighting the cigarette alone is time-consuming and laborious, and there are also problems such as unstable smoke generation, cumbersome operation, and inconvenient counting.

[0004] In view of this, it is necessary to improve the existing smoke generator. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides an automatic smoke generator to solve the problem that the existing smoke generator needs to manually place cigarettes during operation, which is time-consuming and labor-intensive, resulting in unstable smoke generation. It has the functions of automatic cigarette delivery and cigarette lighting, reduces time costs, and improves efficiency. It is achieved through the following technical solutions:

[0006] An automatic smoke generator comprises a silo device, a pushing assembly, a combustion device and an equipment box; the silo device comprises a guide rail and a guide block, the guide rail is connected to the guide block, the guide rail is used to accommodate cigarettes, the guide block is provided with a connecting groove, and the connecting groove is connected to the guide rail; the pushing assembly comprises a push rod and a driving device, the push rod is installed on the driving device, the guide block is provided with a conducting hole, the push rod is inserted into the conducting hole, the guide block is provided with a smoke exhaust hole, and the smoke exhaust hole is connected to the conducting hole; the combustion device comprises a cigarette lighting chamber, the cigarette lighting chamber is connected to the conducting hole, and an igniter is arranged in the cigarette lighting chamber.

[0007] Preferably, the push rod is provided with an end hole, the push rod is provided with a connecting hole, and the end hole is communicated with the connecting hole.

[0008] Preferably, a mounting groove is provided on the push rod, and a first sealing ring is provided at the mounting groove.

[0009] Preferably, the mounting groove is an annular structure, the first sealing ring is annular, and the first sealing ring is installed in the mounting groove.

[0010] Preferably, the combustion device comprises a sealing chamber, the sealing chamber is provided with a mounting hole, the cigarette lighting chamber is provided with a second connecting hole, the mounting hole is connected to the second connecting hole, and the second sealing ring is provided between the mounting hole and the second connecting hole.

[0011] Preferably, the silo device comprises an infrared pair tube, a sensing hole is opened on the guide block, and the infrared pair tube is arranged in the sensing hole.

[0012] Preferably, the infrared pair tube comprises a transmitter and a receiver, and the transmitter and the receiver are respectively arranged at two ends of the sensing hole.

[0013] Preferably, the equipment box is provided with an indicator light and a counting screen.

[0014] Preferably, an air pump is provided in the equipment box, and the equipment box is also provided with an air pump regulating switch, and the air pump regulating switch is connected to the air pump.

[0016] The beneficial effects of the utility model are:

[0017] (1) Driven by the driving device, the push rod moves through the guide hole of the guide block to the cigarette lighting chamber, pushing the cigarette in the guide hole forward. When the push rod pushes the cigarette to the cigarette lighting chamber, it automatically discharges the previous cigarette butt into the sealed compartment, and the lighter ignites the cigarette, realizing the automatic ignition function, reducing time cost and improving efficiency. When the push rod returns to its original position, the cigarette on the guide rail automatically falls into the guide hole, saving the time of manual placement and realizing the effect of automatic cigarette delivery and lighting.

[0018] (2) Sealing rings are provided between the push rod and the sealing chamber to prevent smoke leakage. When the push rod pushes the cigarette into the cigarette lighting chamber and the cigarette is lit, the push rod remains stationary, ensuring that the cigarette burns fully and the released smoke can be fully discharged through the smoke exhaust hole; thus, the problem of unstable smoke generation is solved.

[0019] (3) The equipment box is equipped with a counting screen and indicator light. When the push rod completes a cycle of forward and backward movement, the mechanical switch is triggered to automatically count the number of times. This can reduce manual operation counting; at the same time, the infrared pair tube on the guide block can detect the status of cigarettes in real time, and when the cigarettes are consumed, it can automatically stop.

[0020] It can be seen that the utility model solves the problem that the existing smoke generator needs to manually place cigarettes when working, which is time-consuming and labor-intensive and leads to unstable smoke generation. BRIEF DESCRIPTION OF THE DRAWINGS
