Description

Technical Field

[0001] The present application relates to the field of environmental monitoring, and in particular to an air duct connection mechanism for a regional detector. Background Art

[0002] According to the first-level standardization requirements, the working environment needs to be continuously monitored during on-site confined space operations to ensure that the oxygen content and toxic and harmful gases during the operation are qualified to ensure the personal safety of the workers. At present, area detectors are usually used to continuously monitor the working environment.

[0003] The BZ1 Area Detector is a multi-component gas area detector that can provide readings for up to seven gases simultaneously. Through eighteen compatible sensors, it can monitor oxygen and a variety of toxic and combustible gases. The BZ1 Area Detector can be used outdoors or indoors and is suitable for applications that require operator or site fences, fence line structures, stand-alone equipment, and enclosed space monitoring.

[0004] In the prior art, the inlet connecting pipe of the area detector is only connected to an air duct using a joint. When the area detector is in use, the air duct is pulled back and forth, which can easily cause the joint to break. Especially in winter when the outdoor temperature is low, the joint becomes more brittle and is more likely to loosen, bend, break, or fall off, affecting the measurement results. Utility Model Content

[0005] In response to the above problems, the present application provides a regional detector air duct connection mechanism, which can reduce the failure rate of the regional monitor and improve the measurement accuracy.

[0007] The present application provides an air guide pipe connection mechanism for a regional detector, comprising: an air intake module, an air guide pipe, and a protection spring;

[0008] The input end of the air inhalation module has a Luer connector, and the air guide tube is connected to the Luer connector;

[0009] The protection spring sleeve is arranged on a side of the airway tube outer wall that is connected to the Luer connector.

[0010] In a possible implementation, the regional detector airway tube connection mechanism further includes: an airway tube protection cover;

[0011] The air intake module is provided with a protective cover base arranged around the input end of the air intake module on one side close to the air guide pipe;

[0012] One end of the airway tube protective cover is fixedly connected to the air intake module through the protective cover base, and the airway tube is inserted into the airway tube protective cover.

[0013] In a possible implementation, the protective spring sleeve covers the Luer connector.

[0014] In a possible implementation manner, the airway tube protective cover is engaged with the protective cover base.

[0015] In a possible implementation, the protective cover base is composed of two sector rings.

[0016] In a possible implementation, the outer diameter of the protective cover base formed by the two sector rings is larger than the inner diameter of the airway tube protective cover.

[0017] In a possible implementation, the airway tube protective cover is made of soft material.

[0018] In a possible implementation, the other end of the airway tube protective cover is fixedly connected to an output end of an inhalation probe of the area detector.

[0019] The regional detector air duct connection mechanism provided in the present application can provide protection for the regional detector air duct opening, effectively reducing loosening, bending, breakage and falling off caused by environmental corrosion or improper operation during use, thereby improving the accuracy and precision of the measurement.

Obviously, the described embodiments are part of the embodiments of this application, not all of them.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of this application, unless otherwise specified, "plurality" means two or more.

[0026] Example 1

[0027] Figure 1-2 An air guide pipe connection mechanism for a regional detector provided in an embodiment of the present application includes: an air intake module 1, an air guide pipe 3, and a protection spring 4;

[0028] The input end of the air inhalation module 1 has a Luer connector 2, and the air guide tube 3 is connected to the Luer connector 2;

[0029] The protection spring 4 is sleeved on a side of the outer wall of the air guide tube 3 that is connected to the Luer connector 2 .

[0030] Optionally, the Luer connector 2 is inserted into the airway tube 3 to connect the airway tube 3 with the Luer connector 2 .

[0031] Optionally, the air inhalation module 1 has a gas sensor for analyzing gas components.

[0032] In a possible implementation, the regional detector airway tube connection mechanism further includes: an airway tube protection cover 6;

[0033] The side of the air intake module 1 close to the air guide pipe 3 has a protective cover base 5 arranged around the input end of the air intake module 1;

[0034] One end of the airway tube protective cover 6 is fixedly connected to the air intake module 1 through the protective cover base 5 , and the airway tube 3 is inserted into the airway tube protective cover 6 .

[0035] Optionally, the protective cover base 5 is a double-layer structure, and the airway tube protective cover 6 is disposed between the double-layer structures of the protective cover base 5 .

[0036] In a possible implementation, the protective spring 4 is arranged to cover the Luer connector 2. This implementation can protect the entire connection between the Luer connector 2 and the airway tube 3, which is prone to loosening, bending, breaking, and falling off, by protecting the toughness of the protective spring 4 itself.

[0037] Optionally, the protection spring 4 is of the same length as the air guide tube 3 and covers the entire protection spring 4 .

[0038] In a possible implementation, the airway tube protective cover 6 is engaged with the protective cover base 5 .

[0039] In a possible implementation, the protective cover base 5 is composed of two fan rings. This implementation can facilitate the engagement of the airway tube protective cover 6 with the protective cover base 5 .

[0040] In a possible implementation, the outer diameter of the protective cover base 5 composed of two fan rings is larger than the inner diameter of the airway tube protective cover 6. This implementation enables the airway tube protective cover 6 to be engaged with the protective cover base 5 through its own elasticity.

[0041] In a possible implementation, the airway tube protective cover 6 is made of a soft material. This implementation can facilitate the engagement of the airway tube protective cover 6 with the protective cover base 5 .

[0042] In a possible implementation, the other end of the airway tube protective cover 6 is fixedly connected to the output end of the inhalation probe of the area detector. This implementation enables the airway tube protective cover 6 to cover the entire airway tube 3 and protect the entire airway tube 3.

[0043] Working principle:

[0044] When using the area detector, the area gas is collected by a handheld suction probe, and when the interface of the air duct 3 is bent, the toughness of the protective spring 4 can be used to protect the interface of the air duct 3 at the Luer connector 2, and the air duct protection sleeve 6 can be used to protect the air duct 3 from being corroded by the environment while protecting the air duct 3 when it is bent.
