Abstract
The invention discloses a structure capable of directly calibrating a portable gas detector. The structure comprises a detector shell and a calibration hole and is characterized in that the calibration hole, a first degassing hole and a second degassing hole are formed in the detector shell; and the calibration hole comprises an inserting tube supporting column, an air inlet and a containing tube. By using the structure, the portable gas detector can be more rapidly and conveniently calibrated. Calibration can be realized if only gases exist. An independent calibration hood or air distribution box is not needed. The problems that the operation is troublesome and the calibration hood is easy to lose are avoided. Therefore, the cost for independently manufacturing the calibration hood is saved, and the trouble that the calibration hood is additionally provided during calibration every time can also be eliminated.
Description
Technical field
the present invention relates to a kind of gas analyzer, particularly relate to a kind of structure directly can demarcated portable gas detector.
Background technology
be unsuitable for speedily carry out rescue work or hazardous area inspection etc. the place using stationary gas detector at present, people generally can use portable hand-held gas detector.This type of detector is easy to carry, can use in the environment of various complicated certain danger gas.There is a large amount of use market.
existing portable gas detector timing signal all must use supporting calibration mask, or gas tank.Gas tank is not easy to be carried to hazardous area, and the gas mixing ratio relative complex of gas tank.Time more, people make separately a kind of calibration mask to portable gas detector.Each portable gas detector all needs a kind of calibration mask being applicable to this portable gas detector of design separately like this, and cost of manufacture is very high.And this calibration mask can not be contained on portable gas detector when normal use, needs excision to fall.Easily cause the loss of calibration mask.
Summary of the invention
for the problems referred to above, the object of the invention is a kind of demarcation mouth be directly made on the shell of portable gas detector.Make it both for detection gas at ordinary times, directly can demarcate it at needs timing signal again.
in order to realize object of the present invention, the technical solution adopted in the present invention is: a kind of structure directly can demarcated portable gas detector, comprises detector housing, demarcates mouth; It is characterized in that: described detector housing is provided with demarcates mouth, the first air diffuser, the second air diffuser; Described demarcation mouth comprises intubate pillar, air intake opening, Rong Guan.
be provided with air intake opening in the middle of described intubate pillar, be provided with outside intubate pillar and hold pipe.
the invention has the beneficial effects as follows: the present invention can be quicker, demarcates more easily to portable gas detector.As long as there is gas just can demarcate.Without the need to independent calibration mask or air chest.Avoid the problem that troublesome poeration and calibration mask are easily lost.Which save the cost making separately calibration mask, the trouble that each timing signal installs calibration mask additional can be saved again.

fig. 3 is schematic side view of the present invention.
in figure: 1-first air diffuser, 2-second air diffuser, 3-intubate pillar, 4-air intake opening, 5-holds pipe.
Embodiment
below in conjunction with accompanying drawing, the present invention is described further.
embodiment one:
the structure directly can demarcated portable gas detector, comprises detector housing, demarcates mouth; It is characterized in that: described detector housing is provided with demarcates mouth, the first air diffuser 1, second air diffuser 2; Described demarcation mouth comprises intubate pillar 3, air intake opening 4, holds pipe 5.
be provided with air intake opening 4 in the middle of described intubate pillar 3, be provided with outside intubate pillar 3 and hold pipe 5.
embodiment two:
hose Jacket on intubate pillar 3, is demarcated by air intake opening 4 pairs of sensors by timing signal, and excessive gas is discharged by the first air diffuser 1, second air diffuser 2.The width holding pipe 5 space should be larger than the thickness of soft tube of air inlet.
embodiment two:
air diffuser can be the various shapes such as rectangle, circle, triangle, and intubate pillar 3 can be the shapes such as circular ellipse.Demarcate the part that mouth is directly housing.Do not need other web members to connect.
Claims (2)
