Description

Technical Field

[0001] The utility model relates to the technical field of formaldehyde detection, in particular to a high-efficiency formaldehyde detection box. Background Art

[0002] A formaldehyde test kit is a portable tool used to detect formaldehyde concentrations in indoor air. It works based on a chemical reaction. The kit typically contains a special reagent that changes color when it comes into contact with formaldehyde. The color change is observed as the air and reagent come into contact. The degree of color change is proportional to the formaldehyde concentration in the air. By comparing the color change with a standard color chart or reading chart, the user can estimate the approximate formaldehyde concentration.

[0003] When using the formaldehyde detection kits currently on the market, the test kit is usually placed in a suitable location indoors for testing. Since the indoor air is in a relatively static state, the contact between the air and the reagent is passive, and the indoor air and the reagent cannot fully contact each other. Therefore, it takes a long time to achieve the detection effect, which seriously affects the efficiency of the detection. Therefore, a high-efficiency formaldehyde detection kit is needed.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] See also Figure 1-4 In the utility model: a high-efficiency formaldehyde detection box, including a box body 1, two feeding ports 2 and an air outlet 3 are opened on the top of the box body 1, a motor 4 is embedded in the bottom of the box body 1, the output shaft of the motor 4 is fixedly connected to a rotating rod 5, the top of the rotating rod 5 passes through the box body 1 and extends to the air outlet 3, the top of the rotating rod 5 is fixedly connected to a fan 6, the bottom end of the rotating rod 5 is fixedly connected to four stirring rods 7, and air inlet holes 8 are opened on both sides of the left and right sides of the box body 1.

[0027] In the present invention, when in use, the required reagents can be added to the inside of the box body 1 through the feeding port 2, and then the user turns on the motor 4 to drive the rotating rod 5 to rotate. The rotation of the rotating rod 5 will drive the stirring rod 7 to stir the reagents, thereby allowing different reagents to be fully integrated, thereby improving the detection effect. The rotation of the rotating rod 5 will drive the fan 6 to rotate. After the fan 6 rotates, the air in the temporal part of the box body 1 will be extracted. At this time, the indoor air will rush into the air hole 8 to replenish the inside of the box body 1. As the motor 4 is started, the indoor air will continuously enter the inside of the box body 1, ensuring that the reagent can contact more formaldehyde molecules, thereby improving the accuracy of the detection. Moreover, by accelerating the air flow, sufficient air samples can be collected faster in the box body 1, shortening the detection time, improving efficiency, and ensuring that the air samples collected by the box body 1 are more representative, avoiding the influence of local high concentrations of formaldehyde.

[0028] See also Figure 1-3 , wherein: the inner wall of the feeding port 2 is threadedly connected with a sealing plug 9, and the top height of the sealing plug 9 is higher than the top of the box body 1.

[0029] In the present invention, the sealing plug 9 can seal the feeding port 2 to prevent the air exhausted from the interior of the box body 1 from being drawn back into the interior of the box body 1, thereby improving the practicability of the device.

[0031] In the present invention, the filter plate 12 can filter the air entering the box body 1 to prevent dust in the air from contaminating the reagent, thereby improving the practicality of the device.

[0032] See also Figure 4 , wherein: a disassembly rod 13 is fixedly connected to one side of the filter plate 12, and the disassembly rod 13 is cylindrical in shape.

[0033] In the present invention, the disassembly rod 13 can facilitate the user to disassemble the filter plate 12, thereby improving the practicality of the device.

[0035] In the present invention, the setting of the air adding pipe 14 can draw the air entering the box body 1 into the reagent after the air pump 15 is turned on, thereby allowing the air and the reagent to fully contact, improving the efficiency of the reaction between the reagent and formaldehyde in the air, and accelerating the detection speed.

[0036] See also Figure 1 and 2 , wherein: an observation window 16 is opened on the front of the box body 1, and a transparent plate 17 is fixedly connected to the inner wall of the observation window 16.

[0037] In the present invention, the arrangement of the observation window 16 and the transparent plate 17 can facilitate the user to observe the color change of the reagent, thereby improving the practicality of the device.
