[0032] The working principle and use process of the utility model are as follows: when using the improved smoke gas sampling probe, the external threaded mounting ring 102 is firstly used to rotate and fix the end of the collection tube connected to the end of the gas analyzer, and the sampling probe body 100 is fixedly installed by the external threaded mounting ring 102. Therefore, after the sampling probe body 100 is installed, when the gas analyzer takes samples, the smoke gas on the front surface enters the interior through the end of the main air inlet probe body 101, and at the same time, the smoke gas on the side enters the interior of the main air inlet probe body 101 through the air inlet hole 1011, so that it is convenient to sample and collect the smoke gas uniformly from the surrounding area and enter the interior of the main air inlet probe body 101. The collected gas is filtered again through the filter net 103 and enters the interior of the gas analyzer for analysis and detection, and it is convenient to accurately collect and sample the improved sampling probe body 100, thereby improving the uniformity and detection accuracy of the sampling probe body 100 in smoke gas sampling.

[0033] Then, after the sampling probe body 100 is fixedly installed at the end of the gas analyzer to sample and collect smoke gas for detection, the sampling probe body 100 is placed upside down. When dust falls on the inner surface of the filter 103 and the main air intake probe body 101 and adheres to the surface, the hand-held block 1032 can be taken and moved. When the hand-held block 1032 slides, it drives the rotating block 1034 to rotate inside the rotating groove 2 1035, so that when the hand-held block 1032 rotates, it drives the connecting plate 1037 and the scraper 1036 to rotate, and when the connecting plate 1037 rotates, it drives the cleaning brush 1038 to rotate, and when the cleaning brush 1038 rotates, it drives the rotating block 4 1030 to rotate in the rotating groove 3 1039 The internal rotation causes the connecting plate 1037 and the cleaning brush 1038 to rotate stably, making it convenient for the scraper 1036 to rotate and scrape the inner surface of the main air intake probe body 101 in contact with the scraper, and the cleaning brush 1038 to rotate and sweep the surface of the filter 103 in contact with the scraper, making it convenient to directly rotate and clean the inner surface of the sampling probe body 100 and the filter 103, without the need for disassembly and assembly operations each time for cleaning, making the cleaning process more convenient, and improving the convenience of cleaning the sampling probe body 100 after installation. When collecting samples, the fixing threaded button 1033 is rotated to fix the hand-held block 1032, thereby fixing the connecting plate 1037 and the cleaning brush 1038 for installation.

[0034] Although the embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
