Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the embodiments or the technical solutions in the prior art will be briefly described below. In the drawings, elements or portions are not necessarily drawn to scale.
FIG. 1 is a schematic view of the external structure of the present invention;
fig. 2 is the internal structure schematic diagram of the cylindrical shell after being dissected.
Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1 and fig. 2, one embodiment of the present invention provides a handheld formaldehyde detector, which includes a cylindrical housing 1, a handle 2 and a detecting component; the handle 2 is fixedly connected with the bottom of the cylindrical shell 1; an air suction cavity with an upward opening is arranged at the upper part in the cylindrical shell 1, and an instrument cavity is arranged at the lower part; the side wall of the bottom of the air pumping cavity is provided with an air outlet communicated with the outside; the detection assembly comprises a methanol detector 31, a fan frame 32 and a fan 33; the methanol detector 31 is arranged in the instrument cavity, and a gas probe on the methanol detector 31 penetrates through and extends into the air pumping cavity; the fan frame 32 is fixedly connected to the cylindrical shell 1 at the middle part in the air suction cavity, and the fan 33 is fixedly arranged on the bottom surface of the fan frame 32.
As a specific embodiment, the top surface of the cylindrical shell 1 is provided with an LED lamp 11; the outer side wall of the cylindrical shell 1 is provided with a display screen 12.
In a specific embodiment, the handle 2 is provided with an anti-slip leather sheath 21.
As a specific embodiment, the handle 2 is provided with a control button 22; the methanol detector 31, the fan 33 and the LED lamp 11 are electrically connected with the control button 22.
In a specific embodiment, the bottom of the handle 2 is provided with an adsorption disk 23.
The working principle is as follows:
when the formaldehyde gas exhaust device is used, the control button 22 is pressed to start the fan 33 and the formaldehyde detector 31, the fan 33 defaults to exhaust gas flow into the air exhaust cavity from the opening above the air exhaust cavity, and the air flow flows out of the air outlet on the side wall of the bottom of the air exhaust cavity after being detected by the gas probe of the formaldehyde detector 31 in the air exhaust cavity to form a cycle.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
