Description

Technical Field

[0001] The utility model relates to the technical field of formaldehyde detection, in particular to a portable building formaldehyde detection device. Background Art

[0002] Indoor formaldehyde pollution has attracted much attention. Indoor formaldehyde is now generally considered by all walks of life to be the number one indoor killer. Its release period is generally 3-15 years. It is very serious to the human body, especially infants, pregnant women, the elderly and patients with chronic diseases. The release cycle of toxic gases in the air is relatively long, and it is difficult for residents to detect when it exceeds the standard slightly.

[0003] When in use, the existing formaldehyde detection equipment performs inhalation detection by inhaling the air of the detection equipment. When using this method, firstly, the air inhalation efficiency is low, resulting in low efficiency of the detection process. At the same time, the residual air in the air intake duct will affect the accuracy of the detection, which will lead to the problem that the formaldehyde detection process is affected.

DETAILED DESCRIPTION

[0019] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model.

[0020] Reference Figure 1-3 A portable building formaldehyde detection device comprises a detector 1, a collecting tank 2 is provided on one side of the detector 1, two symmetrically arranged rotating shafts 9 are rotatably connected in the collecting tank 2, a rotating cover plate 3 is fixedly connected to the side wall of the rotating shaft 9, a movable tube 7 is slidably connected through the collecting tank 2, one end of the movable tube 7 located in the collecting tank 2 is fixedly connected to a shrink tube 15, and an air inlet 6 is provided at one end of the movable tube 7;

[0021] A traction mechanism for moving and traction the movable tube 7 is provided in the collecting trough 2, and the traction mechanism includes a mounting frame 12 fixedly connected in the collecting trough 2, a connecting gear 13 is rotatably connected in the mounting frame 12, the connecting gear 13 is coaxial with a rotating gear 14, the connecting gear 13 is meshed with a traction tooth plate 11, and a rotating gear 14 is rotatably connected in the mounting frame 12. A lifting tooth plate 8 is fixedly connected to the side wall of the movable tube 7, the lifting tooth plate 8 is meshed with the rotating gear 14, and the tooth comb density ratio of the traction tooth plate 11 to the lifting tooth plate 8 is 2:3, which can provide a longer extension and compression distance for the lifting tooth plate 8.

[0022] The side wall of the rotating shaft 9 is provided with a driving mechanism for driving the traction mechanism. The driving mechanism includes a driving gear 10 fixedly connected to the side wall of the rotating shaft 9 . A traction tooth plate 11 is slidably connected in the collecting trough 2 , and the traction tooth plate 11 meshes with the driving gear 10 .

[0023] An auxiliary mechanism for assisting the air inlet 6 to intake air is provided on one side of the rotating cover 3 , and the auxiliary mechanism includes an air inlet groove 5 opened on the side wall of the rotating cover 3 , and two symmetrically arranged air inlet fans 4 are fixedly connected in the air inlet groove 5 , and the air inlet fans 4 correspond to the air inlet 6 .

[0024] When the utility model is used, Figure 1-3 As shown, when in use, first turn and open the rotating cover 3, at this time, the air intake fan 4 in the air intake slot 5 starts to work, and the air on both sides of the detector 1 is quickly transported to the air inlet 6. At this time, the auxiliary air intake of the air intake fan 4 can improve the air intake efficiency of the detector 1, that is, improve the efficiency of the detector 1 in the overall formaldehyde detection process. In this process, the rotation of the rotating cover 3 drives the driving gear 10 on the side wall of the rotating shaft 9 to engage with the traction tooth plate 11, and the engagement of the traction tooth plate 11 with the connecting gear 13 can drive the rotating gear coaxial therewith.

At the same time, when the rotating cover plate 3 is closed, the movable tube 7 moves downward in the opposite direction to squeeze the shrink tube 15 downward, and squeezes out the residual air inside it, so as to avoid the problem of interference of the residual air in the pipeline with the next detection process. At the same time, it can provide protection for the movable tube 7 and the air inlet 6 and promote movement during the opening process.
