Abstract
The invention relates to a handheld formaldehyde detector and belongs to the technical field of environmental engineering. The detector comprises a shell, a formaldehyde detection head, a central processing unit, a flow meter and a battery. The two ends of the shell are provided with an air inlet and an air outlet respectively. An air pump is arranged on the air inlet, and the flow meter and the formaldehyde detection head are arranged on the air outlet. The output end of the flow meter and the output end of the formaldehyde detection head are connected with the central processing unit. The output end of the central processing unit is connected with a display screen. The battery supplies power to the air pump, the flow meter, the formaldehyde detection head, the central processing unit and the display screen. According to the handheld formaldehyde detector, the air amount is counted through the flow meter, the formaldehyde amount is counted through the formaldehyde detection head, the formaldehyde concentration can be obtained instantly, and the detector is simple and effective.
Description
Technical field
The present invention relates to a kind of hand-held methylene oxide detecting instrument, belong to field of environment engineering technology.
Background technology
Existing methylene oxide detecting instrument is longer for detection time, can not reflect the concentration change of formaldehyde in real time.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, proposes a kind of portable, immediately can test the detector of concentration of formaldehyde.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of hand-held methylene oxide detecting instrument, comprising: housing, formaldehyde detecting head, central processing unit, flowmeter and battery; The two ends of described housing are shaped with air intake opening and gas outlet respectively; Described air intake opening place is provided with air pump, described flowmeter and formaldehyde detecting head and is arranged at described gas outlet place; Described flowmeter is connected described central processing unit with the output terminal of formaldehyde detecting head; The output terminal of described central processing unit is connected to display screen; Described battery is described air pump, flowmeter, formaldehyde detecting head, central processing unit and display screen are powered.
Such scheme further improves and is: described housing has the interface for described battery charges.
Such scheme further improves and is: described air intake opening is equipped with screen pack.
Hand-held methylene oxide detecting instrument provided by the invention, utilizes flowmeter to add up and enters air capacity, with formaldehyde detecting head statistics formaldehyde amount, immediately can draw concentration of formaldehyde, simply, effectively.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the present invention's preferred embodiment structural representation.
Number in the figure is schematically as follows: 1-housing, 2-air intake opening, 3-gas outlet, 4-air pump, 5-formaldehyde detecting head, 6-screen pack, 7-flowmeter.
Embodiment
Embodiment
The hand-held methylene oxide detecting instrument of the present embodiment, as shown in Figure 1, comprising: housing 1, formaldehyde detecting head 5, central processing unit, flowmeter 7 and battery; The two ends of housing 1 are shaped with air intake opening 2 and gas outlet 3 respectively; Air intake opening 2 place is provided with air pump 4, flowmeter 7 and formaldehyde detecting head 5 and is arranged at gas outlet 3 place; Flowmeter 7 is connected central processing unit with the output terminal of formaldehyde detecting head 5; The output terminal of central processing unit is connected to display screen; Battery is that above consuming parts is powered.
After starting the detector of the present embodiment, flowmeter 7 and formaldehyde detecting head 5 standby, air pump 4 starts, and according to housing 1 size, the air time replaced in housing is about 1 minute completely, so, flowmeter 7 and formaldehyde detecting head 5 standby 1 point started after 30 seconds, after starting latter 1 minute, and the air mass flow that central processing unit is added up according to flowmeter 7 and the formaldehyde amount that formaldehyde detecting head 5 detects, calculate concentration of formaldehyde, display on a display screen.
Screen pack 6 is also equipped with at air intake opening 2 place, prevents dust from blocking formaldehyde detecting head 5, affects measurement result.
The present invention is not limited to above-described embodiment.All employings are equal to the technical scheme of replacing and being formed, and all drop on the protection domain of application claims.
