Description
Technical field
The invention relates to formaldehyde examination instrument more particularly to a kind of Portable formaldehyde detection instruments.
Background technique
Currently, health is increasingly paid attention to due to people, the working environment or life living environment to surrounding are good for
Health is increasingly paid close attention to.Especially newly-decorated workshop or house, inside contain volatile contaminant, wherein endangering maximum is exactly first
Aldehyde, formaldehyde can all bring biggish harm to environment and human body as being a kind of common pollution gas.Therefore it often needs to life
Living or work space carries out formaldehyde examination to guarantee Environmental Health, currently in order to portable will use portable formaldehyde examination
Instrument, it will usually which a detector is set outside detector, and hand-held detector tests the air of additional space, but this instrument
When idle, the bad placement of detector may wind up with route, interfere subsequent use.
Summary of the invention
The technical problem to be solved in the embodiments of the present application is that providing a kind of Portable formaldehyde detection instrument.
The embodiment of the present application is realized through the following technical scheme: a kind of Portable formaldehyde detection instrument, including detection
Instrument ontology and detection probe；The detector outer body wall is provided with elastic clip；The detection probe outer wall be provided with
Elastic clip matches the annular grooving being caught in for elastic clip；Vented cavity, the vented cavity are provided in the middle part of the detection probe
One end is opening, and the other end is connect with detector ontology by soft air-guide pipe, is equipped with inside the vented cavity towards soft air-guide pipe
The blower of blowing.
Further, one layer is provided in the vented cavity for absorbing the drying layer of moisture.
Further, one layer is provided in the vented cavity for absorbing the dust adsorption layer of dust.
Further, the elastic clip is a circular arc item for being greater than semicircle, the inner radii and ring of the elastic clip
The matching of shape grooving inner wall radius.
Further, there are two the elastic clip and annular grooving are correspondingly arranged.
Further, the elastic clip is made of plastic cement material.
Beneficial effect is: by the cooperation of elastic clip and annular grooving, detection probe can be caught on elastic clip real
Stablizing when now leaving unused is placed, to will not wind with soft air-guide pipe, facilitates subsequent use.
Detailed description of the invention
It is described in further detail below in conjunction with specific embodiment of the attached drawing to the embodiment of the present application, in which:
Fig. 1 is that the detection probe of the embodiment of the present application is caught in the structural schematic diagram under elastic clip state；
The detection probe and the structural schematic diagram under elastic clip discrete state that Fig. 2 is the embodiment of the present application；
Fig. 3 is the schematic diagram of internal structure of the detection probe of the embodiment of the present application.
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the embodiment of the present application, with reference to the accompanying drawing to this
Application embodiment is described in detail, the description of this part be only it is exemplary and explanatory, should not be to the guarantor of the embodiment of the present application
Shield range has any restriction effect.
As shown in figures 1 and 3, a kind of Portable formaldehyde detection instrument, including detector ontology 1 and detection probe 2；The inspection
It surveys 1 front setting screen of instrument ontology and button, lateral wall is provided with elastic clip 11, detector ontology 1 is internally provided with formaldehyde
The equipment of detection, specially formaldehyde sensor, detection probe 2 direct the air into detector ontology 1 for detection；The detection is visited
First 2 outer wall is provided with the annular grooving 21 for matching with elastic clip 11 and being caught in for elastic clip 11；Specifically, detection probe 2 is in
Cylindrical shape, elastic clip 11 is circular arc item, and circular arc is greater than semicircle and is less than full circle, reserves one and is caught in mouth so as to detection probe 2
It is caught in, the inner radii of the elastic clip 11 is matched with annular 21 inner wall radius of grooving.Elastic clip 11 is by elastic material system
At with certain elastic deformability so that detection probe 2 is caught in.Preferably, the elastic clip 11 is by plastic cement material system
At for example, by using the material of PC+ABS.In order to guarantee to stablize clamping detection probe 2, the elastic clip 11 and annular grooving 21
There are two being correspondingly arranged.
Vented cavity 22 is provided in the middle part of the detection probe 2, described 22 one end of vented cavity is opening, and the other end passes through air guide
Hose 3 is connect with detector ontology 1, and the blower 25 dried towards soft air-guide pipe 3 is equipped with inside the vented cavity 22.Soft air-guide pipe
3 are made of soft material, such as rubber tube etc..To make the impurity in air not influence detection effect, set in the vented cavity 22
One layer is equipped with for absorbing the drying layer 23 of moisture.Drying layer 23 is made of the good material of hygroscopicity, and intermediate is cellular
So that air passes through.One layer is provided in the vented cavity 22 for absorbing the dust adsorption layer 24 of dust, in order to avoid dust
It influences subsequent detection and leads to 1 building up inside dust of blower 25 and detector ontology.
