Survey connector of the entrance in gas inlet channel as the blow gun.
Based on above-mentioned, which further includes heating module, and the heating module is arranged in the air suction module.
Based on above-mentioned, the blow gun is anti-suck blow gun.
Based on above-mentioned, disposable blow gun is provided on the blow gun.
Based on above-mentioned, the bleeding point of the air suction module is provided with air filter cover.
Air-extractor based on above-mentioned, described air suction module uses fan, exhaust fan or micro air pump.
The present invention has substantive distinguishing features outstanding and significant progress compared with the prior art, and specifically, the present invention exists
In the case where not changing existing gas detection equipment main structure, no replacement higher gas detection sensor of precision, pass through
Gas washing is carried out to gas detection equipment using clean air, make similarly to check equipment in a short time Reusability the case where
It is lower still to keep a metastable detection accuracy.In the use of the present invention, only needing one, the set on anti-suck blow gun general
Logical disposable blow gun, with conventional detection devices directly using disposable anti-suck blow gun compared with, the present invention used in
It can be used repeatedly for anti-suck blow gun, greatly reduces the testing cost of user.

Specific embodiment
Below by specific embodiment, technical scheme of the present invention will be described in further detail.
As shown in Figs. 1-2, a kind of portable gas detection device tube cleaning arrangement, including gas entrance passage to be detected
1, air suction module 4, gas washing head 2, heating module 5 and anti-suck blow gun 3；The heating module 5 is arranged in the air suction module 4
Interior, the bleeding point of the air suction module 4 is provided with air filter cover 6；
The gas washing head 2 includes gas outlet 11, detection gas inlet channel 12 and gas washing chamber 13；The gas washing chamber 13 passes through air flue
The gas outlet of the 8 connection air suction modules 4；The gas outlet 11 is taper gas outlet, and the narrow end of the taper gas outlet is connected to
The wide end of the gas entrance passage to be detected 1, the taper gas outlet is connected to the gas washing chamber 13；The detection gas air inlet
Channel 12 is arranged in the gas washing chamber 13, and the outlet of the detection gas inlet channel 12 corresponds to the gas access to be detected
Channel 1 is arranged, connector of the entrance of the detection gas inlet channel 12 as the anti-suck blow gun 3.The anti-suck
Disposable blow gun 7 is provided on blow gun 3.
When specifically used, the air-exhaust method that the air suction module 4 uses includes fan degassing method, exhaust fan pumping
Which kind of air-exhaust method gas method, micro air pump degassing method etc., the air suction module specifically use can be in actual equipment use
It is determined according to the actual needs of gas detection equipment work.
As shown in figure 5, judgement is according to testing result after portable gas detection device completes a gas detection
It is no to need to carry out circuit-cleaning operation, if it is not required, then being detected work next time, if it is desired, it is clear then to trigger pipeline
Wash journey starts apparatus of the present invention.
As shown in fig. 6, pipeline cleaning flow chart of the invention.The workflow of pipeline cleaning part is to trigger pipeline first
Purge event filters out the impurity in air by the air filter cover 6, and the air suction module 4, which extracts, passes through filtered cleaning
Then air judges whether to be heated according to the actual working environment of equipment, if necessary to heat, then heating module is opened
Begin to carry out heating operation, next circuit-cleaning operation is carried out according to preset gas washing program, when pipeline cleaning reaches preset
Between after, air suction module 4 stops working, pipeline cleaning work complete.Specifically, when equipment is too low using temperature, in gas washing
Start heating module and carries out gas heating.
As shown in figure 3, tube cleaning arrangement of the invention carries out gas circuit schematic diagram when pipeline cleaning work, detection device pipe
After the starting of road cleaning procedure, air is under the driving of air suction module 4, into device, under the guidance of air flue 8, into gas washing
First 3, after the gas outlet of gas washing head 3 11 is accelerated and rotated, into gas entrance passage 1 to be detected, start to gas
Detection device carries out pipeline cleaning, simultaneously as the air velocity at the gas outlet 11 of gas washing head 2 is fast, air pressure is small, remains in inspection
The gas surveyed at gas inlet channel 12 also flows to gas entrance passage 1 to be detected under the action of draught head, and finally from inspection
The discharge of measurement equipment gas outlet.If the environment temperature that equipment uses is relatively low, heating module 5 starts work, starts to set detection
Standby internal subenvironment is heated.
As shown in figure 4, tube cleaning arrangement of the invention carries out gas circuit schematic diagram when gas detection work, when progress gas
When detection, gas to be detected passes through gas washing head 2 by anti-suck blow gun 3 and enters gas entrance passage 1 to be detected, the anti-suck
The escape pipe 31 of blow gun 3 is completely plugged by the gas outlet 11 of gas washing head 2, prevents because draught head causes air to pass through gas washing head 2
Into gas detection equipment, detected gas is diluted, influences detection accuracy.
Finally it should be noted that: the above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, it should be understood by those ordinary skilled in the art that: still
It can modify to a specific embodiment of the invention or some technical features can be equivalently replaced；Without departing from this hair
The spirit of bright technical solution should all cover within the scope of the technical scheme claimed by the invention.
