Ring and outer shroud, the inner ring centre is to fall sample channel；Marmon clamp slit between the inner ring and outer shroud circularizes air flue, is used for
Gas is set to form annular airflow；The top of the annular air channel is provided with air inlet, the lower face opening shape of the annular air channel
Gas outlet is circularized, and is stretched in ventilative crucible.
As a further improvement of the above technical scheme：
The upper end face closure of the annular air channel, the air inlet are located at the side on the outer shroud top.
The upper surface of the snorkel is provided with the first tube socket, and the first inlet channel is provided on first tube socket；Institute
The top loop for stating snorkel is equipped with the second header, is provided with the second inlet channel of L-shaped in the second header, one end and described the
One inlet channel is connected, and the other end is connected with air inlet；It is connected by fastener between first tube socket and the second header.
The fastener is trip bolt.
First tube socket and the second header are provided with seal assembly between outer shroud respectively.
The seal assembly is ring type seal.
Compared with the prior art, the advantages of the present invention are as follows：
The Jun Liu mechanisms for elemental analyser of the present invention, the annular air channel being made up of inner ring in snorkel and outer shroud, make
The gas being passed through forms annular airflow, and the sample in the middle part of annular airflow is completely cut off with outside air, ensures sample in pure oxygen environment
Lower fully burning；Snorkel lower end is inserted directly into ventilative crucible, the splashing of sample when can avoid being loaded；In addition sample
The gas generated after burning is directly taken out of by oxygen stream from the bottom of ventilative crucible, and it is residual in crucible to can avoid experimental gas
It stays, improves experimental precision.

Specific implementation mode
Below in conjunction with Figure of description and specific embodiment, the invention will be further described.
As depicted in figs. 1 and 2, the Jun Liu mechanisms for elemental analyser of the present embodiment, including with a source of oxygen（In figure
It is not shown）The snorkel 1 being connected, snorkel 1 include inner ring 101 and outer shroud 102, are to fall sample channel 103 among inner ring 101；
Marmon clamp slit between inner ring 101 and outer shroud 102 circularizes air flue 104, for making gas form annular airflow；Annular air channel
104 top is provided with air inlet 105, and the lower face opening shape of annular air channel 104 circularizes gas outlet 106, and stretches to
In gas crucible 5.The Jun Liu mechanisms for elemental analyser of the present invention are made up of inner ring 101 in snorkel 1 and outer shroud 102
Annular air channel 104, so that the gas being passed through is formed annular airflow, sample 6 and the outside air in the middle part of annular airflow completely cut off, protect
Card sample 6 fully burns under pure oxygen environment；1 lower end of snorkel is inserted directly into ventilative crucible 5, when can avoid sample-adding
The splashing of sample 6；In addition the gas that sample 6 generates after burning directly is taken out of by oxygen stream from the bottom of ventilative crucible 5, can keep away
Exempt from experimental gas to remain in crucible, improves experimental precision.
In the present embodiment, the upper end face closure of annular air channel 104, air inlet 105 is multiple, is evenly distributed on outer shroud 102
The side on top.
In the present embodiment, the upper surface of snorkel 1 is provided with the first tube socket 2 in Π shapes, and the first tube socket 2 covers on snorkel
On 1, the first inlet channel 201 is provided on the first tube socket 2, as shown in Fig. 2, the first inlet channel 201 is multiple, it is uniformly annular
It is distributed on the first tube socket 2；The top side of snorkel 1 is equipped with the second header 3, and L-shaped second is provided in the second header 3
Inlet channel 301, one end are connected with the first inlet channel 201, and the other end is then connected with air inlet 105, due to using multiple
