The further improvement lies in, the filter cartridge construction includes level-one filter core and second level filter core, the one of the level-one filter core End is connected by conduit with the probe, and the other end of level-one filter core is connected by conduit with the second level filter core, and described two Grade filter core is connected to quick connector.

The further improvement lies in, the display module is connected to gyroscope, the use state of handle passes through the gyro Instrument detection.

The further improvement lies in, the pneumoelectric connector passes through gas-guide tube respectively and power supply communication line is connected to the master Machine.

The further improvement lies in, the conduit is internal diameter 0.5mm, the stereotypes hoses of outer diameter 5mm.

The built-in infrared sensor handle apparatus of the utility model makes it have following due to using above technical scheme Effect:

The utility model is structurally reasonable, easy to operate, uses double-filtration mode, more effectively carries out front end filtering, To protecting sensor, substantially prolong the service life of sensor, not only precision it is high, again can than in relatively rugged environment surely Fixed work, accurately detects working environment.

Detailed description of the invention

Fig. 2 is the schematic diagram of internal structure of the utility model built-in infrared sensor handle apparatus.

Appended drawing reference in corresponding Figure of description is with reference to as follows:

Probe 1, sensor 2, quick connector 3, function button 4, display module 5, pneumoelectric connector 6, conduit 7, gas-guide tube 8, Power supply communication line 9, host 10, level-one filter core 20, second level filter core 30, gyroscope 40.

Specific embodiment

In order to realize utility model technological means, create feature, reach purpose and effect is easy to understand, lower knot Conjunction is specifically illustrating, and the utility model is further described.

The embodiments of the present invention provide a kind of built-in infrared sensor handle apparatus, as shown in Fig. 2, including hand Handle, handle includes probe 1, gentle set on internal sensor 2, filter cartridge construction, quick connector 3, function button 4, display module 5 Electric connection 6, filter cartridge construction are connect by conduit 7 with quick connector 3, and conduit 7 uses the stereotypes hoses of internal diameter 0.5mm outer diameter 5mm, 7 angle of bending conduit, the various testing requirements of flexible adaptation, quick connector 3 it can pass through gas-guide tube 8 and 2 phase of sensor as requested Even, sensor 2 is connected separately with function button 4 and display module 5, and display module 5 is connected to 2.4 inches of high-definition liquid crystals and shows Screen, display screen are embedded in handle, user can be allowed to observe detection data in time；It can be with when environmental pollution is serious generates false alarm The operation such as it is zeroed out with the function button 4 on handle；Pneumoelectric connector 6 is connected to sensor 2 and host 10, and pneumoelectric Connector 6 is connected to host 10, pneumoelectric connector 6 and gas-guide tube 8, power supply communication line 9 by gas-guide tube 8 and power supply communication line 9 respectively Between be respectively equipped with air pump, air pump maximum coutroi velocity is 2L/min.

Specifically, filter cartridge construction includes level-one filter core 20 and second level filter core 30, one end of level-one filter core 20 passes through conduit 7 It is connected with probe 1, it is fast and simple can to cross most of impurity, substitute mode in air filtering for high-precision copper sintered filter core；Probe 1 The case where detecting leakage point, the sucking of 1 structure of open probe is wide, and sampling is more complete to stablize；The other end of level-one filter core 20 is logical It crosses conduit 7 to be connected with second level filter core 30, second level filter core 30 can be changed to waterproof filter element under necessary condition, adapt to various work Environment, and second level filter core 30 is connected to quick connector 3.

In addition, display module 5 is connected to gyroscope 40, the use state of handle is detected by gyroscope 40, when environment dirt Dye is serious the operation such as can be zeroed out when generating false alarm with the function button 4 on handle.

In use, when probe 1 has detected leakage point, by after air entry suction lead 7 through 20 mistake of level-one filter core Most of impurity in air is filtered, then partial moisture and irritative gas are filtered out into second level filter core 30 by conduit 7, Then it is detected by sensor 2, conversion output electric signal after being detected using infrared principles, and will test data and be shown in display mould On block 5, operation can be zeroed out etc. with the function button 4 on handle when environmental pollution is serious generates false alarm；Then it passes Sensor 2 is separately connected gas-guide tube 8 and power supply communication line 9 after pneumoelectric connector 6 and air pump, is finally connected to host 10 and is observed It is operated with the statistics of data etc.；When the use state that gyroscope 40 detects handle is transferred to when placement 30 seconds or more stationary Standby mode reduces the power consumption of complete machine.

The built-in infrared sensor handle apparatus of the utility model, it is structurally reasonable, easy to use, it not only can will be in air Contaminant filter completely can also precisely detect the air conditions of environment, and be provided with numerical value on handle and show that equipment and operation are pressed Button, can observe in time numerical value and inhibit interference etc. operation, bring convenience to users, industry, refrigeration, heating or electric power row Industry all has very high practicability.

The specific embodiment of utility model is described above.It is to be appreciated that utility model is not limited to Above-mentioned particular implementation, devices and structures not described in detail herein should be understood as is given with the common mode in this field To implement；Those skilled in the art, which can make various deformations or amendments within the scope of the claims and make, several simply to push away It drills, deform or replaces, this has no effect on the substantive content of utility model.
