Description
Technical field
The utility model relates to a kind of detection analytical equipment, specifically a kind of formaldehyde content in indoor air self-testing device.
Background technology
Newly-decorated room all need to window a very long time of ventilating could live, and this is to allow formaldehyde emission go out by air circulation.Formaldehyde, also known as formaldehyde, chemical formula is HCHO, is a kind of colourless gas having special pungent odour.The main harm of formaldehyde is to Mucocutaneous spread effect, formaldehyde is when indoor reach finite concentration, people will not feel well, people can feel furious, throat discomfort, hoarseness, uncomfortable in chest, dermatitis etc., acute poisoning can be caused when concentration of formaldehyde is too high, show as expiratory dyspnea, allergic dermatitis, pulmonary edema etc., formaldehyde also has very strong carcinogenicity.The existing proprietary instrument of instrument Dou Shi company carrying out indoor formaldehyde content mensuration in the market, costly, and surveying instrument is bulky for instrument price, and the testing cost of carrying out indoor formaldehyde content is relatively high.
Utility model content
The purpose of this utility model is to provide a kind of formaldehyde content in indoor air self-testing device, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of formaldehyde content in indoor air self-testing device, comprise gas production bag, connecting pipe, clip, test tube and test tube rack, the capacity of described gas production bag is 10L and gas production bag is provided with straight-through connector, gas production bag is provided with the scale mark for showing volume, connecting pipe one end is connected with straight-through connector, the connecting pipe other end is connected in test tube, test tube rack is provided with test tube putting hole and the groove for placing absorbing agent medicine bottle, clip is on connecting pipe, test tube is provided with test tube with the use of test tube plug, test tube plug top is provided with escape pipe, test tube is arranged in the test tube putting hole of test tube rack.
As further program of the utility model: test tube is more than one with the quantity of test tube putting hole and test tube is consistent with the quantity of test tube putting hole.
As further program of the utility model: connecting pipe adopts ABS material to make.
Compared with prior art, the beneficial effects of the utility model are: this apparatus structure is simple, reasonable in design, compact, and floor area is little; Without the need to the instrument of costliness, equipment cost is low, and content of formaldehyde measured value is accurate; This device operates without the need to professional, simple to operation, and practicality is good, and use cost is low, long service life; This device can carry out the measurement of content of formaldehyde simultaneously to three rooms, work efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of formaldehyde content in indoor air self-testing device.
Wherein: 1-gas production bag, 11-leads directly to connector, 2-connecting pipe, 3-clip, 4-test tube, 5-test tube plug, 6-test tube rack, 7-absorbing agent.
Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1, a kind of formaldehyde content in indoor air self-testing device, comprise gas production bag 1, connecting pipe 2, clip 3, test tube 4 and test tube rack 6, the capacity of described gas production bag 1 is 10L and gas production bag 1 is provided with straight-through connector 11, gas production bag 1 is provided with the scale mark for showing volume, connecting pipe 2 one end is connected with straight-through connector 11, connecting pipe 2 other end is connected in test tube 4, test tube rack 6 is provided with test tube 4 putting hole and the groove for placing absorbing agent 7 medicine bottle, clip 3 is clipped on connecting pipe 2, test tube 4 is provided with test tube 4 with the use of test tube plug 5, test tube plug 5 top is provided with escape pipe, test tube 4 is arranged in the test tube putting hole of test tube rack 6.Test tube 4 is more than one with the quantity of test tube putting hole and test tube 4 is consistent with the quantity of test tube putting hole.Connecting pipe 2 adopts ABS material to make.
Principle of work of the present utility model is: the window and door that need the room detected all are closed 1 hour, carries out other preliminary works during this period; Absorbing agent 7 is poured in test tube 4 to scale mark 5 place (representing 5ml); 1 hours is to afterwards, connecting pipe 2 is connected with straight-through connector 11 and connecting pipe 2 is bent 180 degree, clip 3 is adopted to clamp connecting pipe 2, in room to be measured, open gas production bag 1 fill air to scale mark until gas production bag 1, again connecting pipe 2 to be inserted in test tube 4 and to adopt test tube plug 5 to clog test tube 4, open clip 3, slowly apply pressure and gas slowly is entered in test tube 4 absorbed by absorbing agent 7, avoid because overexert the liquid ejection test tube plug 5 caused; After absorption, take out test tube plug 5, in test tube 4, add developer and shake test tube 4 gently, leaving standstill after 15 minutes, observe the color of liquid in test tube 4 and find out corresponding content to contrasting than vitta, being measured result.
Table 1 survey by this device data and special instrument survey the correlative value of data, error range is less than 6%, and error is in tolerance interval.
