Description

Technical Field

[0001] This application relates to the field of gas detection equipment, and in particular to an on-site detection device for organic substances in indoor air. Background Technology

[0002] TVOCs refer to a general term for organic substances that are easily volatile at room temperature. They exist in the air in the form of vaporization at room temperature. Their toxicity, irritancy, carcinogenicity, and distinctive odor can affect the skin and mucous membranes, causing acute damage to the human body.

[0003] Indoor TVOCs mainly originate from combustion products of coal and natural gas, smoke from smoking, heating, and cooking, adhesives, paints, varnishes, boards, wallpapers, etc. in building and decoration materials, furniture, household appliances, cleaning agents, and emissions from the human body itself. Indoor TVOC concentrations are typically around 0.2 mg / m³. 3 Up to 2mg / m 3 Between 0.16 mg / m³, indoor TVOC concentration 3 ~0.3mg / m 3 At normal temperatures, TVOC levels are generally harmless to human health, but these levels often exceed safe limits during home renovations, especially under improper conditions. Currently, on-site TVOC testing primarily relies on handheld VOC detectors.

[0004] Due to the convenience of handheld VOC detectors, users can perform the tests by hand. However, in multi-room venues such as hotels, guesthouses, and KTVs, handheld testing is not only labor-intensive, but also prone to errors in the test results due to variations in the height and angle of the handheld device when different users are testing. Utility Model Content

[0005] To address the issues of high labor intensity in handheld testing in multi-room locations and discrepancies in test results caused by switching between different users, this application provides an on-site testing device for organic substances in indoor air.

[0006] The technical solution adopted in this application for an indoor air organic matter on-site detection device is as follows:

[0007] An indoor air organic matter on-site detection device includes a handheld detector body, a base, a connecting rod, and a placement platform; the base and the placement platform are connected by the connecting rod; the placement platform is for placing the handheld detector body.

[0008] By adopting the above technical solution, and utilizing the limitation of the connecting rod length, along with the base and placement platform, the handheld testing instrument body can be made convenient to operate while providing a placement area with a limited height for the handheld testing instrument body. This reduces the labor intensity of holding the instrument for a long time, and ensures that the testing height and angle are standardized when different users perform the testing operation, thereby improving the problem of deviation in testing results when different users perform the testing operation.

[0009] Optionally, the base has an internal cavity; the side wall of the base has a water inlet; the water inlet is connected to the cavity of the base.

[0010] By adopting the above technical solution, the weight of the base can be increased or decreased by using the water inlet. On the one hand, this makes the base easier to carry, and on the other hand, it can add weight to the base on site, improving the stability of the base and reducing the risk of the handheld detector falling due to human impact.

[0011] Optionally, the surface of the base is provided with a first storage slot, a second storage slot, and a third storage slot; the first storage slot is used to store the handheld detector body; the second storage slot is used to store the placement platform; the connecting rod is a telescopic rod, and the two ends of the connecting rod are detachably connected to the base and the placement platform respectively; the third storage slot is used to store the connecting rod.

[0012] By adopting the above technical solution, the overall storage space is reduced. Furthermore, the hollow base further reduces the overall weight that can be carried.

[0013] Optionally, the base is provided with a cover cloth for covering the first storage slot, the second storage slot and the third storage slot; the side wall of the base is provided with a buckle; the male and female parts of the buckle are respectively connected to the base and the cover cloth.

[0014] By adopting the above technical solution, the risk of the handheld detector, connecting rod, and placement platform falling off the base during transportation is reduced by covering them with a tarpaulin. At the same time, it provides protection for the handheld detector and reduces the risk of sharp objects from the outside scratching the handheld detector.

[0015] Optionally, the side wall of the base is provided with an elastic band, and the two ends of the elastic band are respectively fixed to the base; the elastic band is used to fix the cover cloth in the rolled-up state.

[0016] By adopting the above technical solution and introducing the elastic band, the cover can be folded and stored, improving the problem of scattered cover hindering the transfer of the base and being stepped on by users.

[0017] Optionally, the base is provided with a handle, and the side wall of the base is provided with an exhaust port; the exhaust port is connected to the cavity of the base, and the water inlet and the exhaust port are respectively located on both sides of the handle.

[0018] By adopting the above technical solution, on the one hand, the introduction of the handle facilitates the handling of the base, and on the other hand, the introduction of the vent allows air to circulate in the cavity and water to flow smoothly during the filling and draining of the base. At the same time, it also allows for timely monitoring of whether the cavity is full of water.

[0019] Optionally, the base is provided with anti-slip pads on the side facing away from the connecting rod.

[0020] By adopting the above technical solution, the problem of wear and tear caused by prolonged contact and friction between the base and the ground can be improved.

[0021] Optionally, the surface of the handheld detector body away from its own operating interface and the surface of the placement platform are respectively connected to mutually magnetic sheets.

[0022] By adopting the above technical solution, the handheld detector can be easily placed on and taken off the platform at any time, while reducing the risk of the handheld detector falling off the platform due to human touch on the base.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] By utilizing the limited length of the connecting rod, along with the base and placement platform, the handheld testing instrument body can be made convenient to operate while providing a placement area with a limited height for the handheld testing instrument body. This reduces the labor intensity of holding the instrument for a long time, and ensures that the testing height and angle are consistent when different users perform the testing operation, thereby improving the problem of deviation in testing results when different users perform the testing.

[0025] The base has a first, second, and third storage slot, which, together with a cover, allows the base to not only function as a base but also as a storage box for the handheld detector and connecting rod, compressing the overall storage space while making it easy to carry.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses an indoor air organic matter on-site detection device, which, while taking into account the portability of the handheld detector, improves the problem of high labor intensity of handheld detection in multi-room locations and deviations in detection results caused by different users.

[0034] Reference Figure 1 and Figure 2 An indoor air organic matter on-site detection device includes a handheld detector body 1, a base 2, a connecting rod 3, and a placement platform 4. The handheld detector body 1 is used to detect the concentration of TVOC in the air. The connecting rod 3 is a telescopic rod, and its two ends are detachably connected to the base 2 and the placement platform 4, respectively. The placement platform 4 is used to place the handheld detector body 1.

[0035] Reference Figure 2 Specifically, the surface where the base 2 connects to the connecting rod 3 is defined as the front of the base 2, the surface facing away from the connecting rod 3 is defined as the back of the base 2, and the four sides of the base 2 are defined as the top, bottom, left, and right side walls of the base 2. The base 2 has an internal cavity.

[0036] Reference Figure 2 The base 2 has a first storage slot 21, a second storage slot 22 and a third storage slot 23 on its front side. The first storage slot 21 is used to store the handheld detector body 1, the second storage slot 22 is used to store the placement platform 4, and the third storage slot 23 is used to store the connecting rod 3.

[0037] Reference Figure 2A cover 5 is provided on the base 2 to cover the first storage slot 21, the second storage slot 22, and the third storage slot 23. One side of the cover 5 is glued to the right side wall of the base 2, and the other side is fixed to the left side wall of the base 2 with a fastener 6, thus achieving the binding and protection effect of the cover 5 on the handheld detector body 1 during the transfer of the base 2. An elastic band 7 is provided on the right side wall of the base 2, and the two ends of the elastic band 7 are fixed to the upper and lower side walls of the base 2, respectively. The elastic band 7 is used to fix the cover 5 in the rolled-up state.

[0038] Reference Figure 3 The upper side wall of the base 2 is provided with a water inlet 24 and an air vent 25, both of which are connected to the cavity of the base 2. A handle 26 is integrally formed between the water inlet 24 and the air vent 25 on the base 2 to facilitate the handling, water filling, and drainage of the base 2. Anti-slip pads 8 are attached and fixed to the back of the base 2 to improve the problem of wear and water leakage caused by prolonged contact and friction with the ground.

[0039] Reference Figure 4 and Figure 5 To further reduce the overall storage space, in this embodiment, the detachable connection between the connecting rod 3 and the base 2 and the placement platform 4 is a threaded connection. Of course, in other embodiments, the detachable connection can be a plug-in connection, a bolt connection, etc. The threaded hole where the base 2 and the connecting rod 3 are threaded is located in the second storage groove 22, and in the stored state, the threaded hole is covered by the placement platform 4, reducing the accumulation of external debris in the threaded hole.

[0040] Reference Figure 5 The placement platform 4 includes a rectangular plate 41 and baffles 42 located on opposite sides of the rectangular plate 41. The structure of the placement platform 4 is consistent with that of the channel steel. Magnetic sheets (not shown in the figure) are respectively bonded to the surfaces of the placement platform 4 between the opposite baffles 42 and the surface of the handheld detector body 1 facing away from its operating interface. This reduces the risk of the handheld detector body 1 slipping on the placement platform 4. Of course, the magnetic sheets can be flat or tilted to fix the detection angle of the handheld detector body 1.

[0041] The implementation principle of an indoor air organic matter on-site detection device according to an embodiment of this application is as follows: Separate the male and female parts of the buckle 6, roll up the cover cloth 5, and use the elastic band 7 to fix the cover cloth 5 in the rolled-up state. Take out the handheld detector body 1, the placement platform 4, and the connecting rod 3. Fill the base 2 with water and stretch the connecting rod 3. Connect the two ends of the base 2 to the designated positions on the base 2 and the placement platform 4, respectively. Hold the handheld detector body 1, turn it on, and perform a self-test. Grasp the connecting rod 3 or the handle 26 and go to the designated room to perform TVOC detection.

[0042] After placing the base 2 at the testing point, press the testing button on the handheld testing device 1 to start the testing. After the testing time is completed, move to the next room for testing. When changing personnel en route, inform them of the operating method of the handheld testing device 1 to hand over the testing work. In this way, by utilizing the limited length of the connecting rod 3, together with the base 2 and the placement platform 4, the handheld testing device 1 can be made convenient to operate while providing a limited height placement area, reducing the labor intensity of holding it for a long time. Furthermore, when different users are changing testing operations, the testing height and angle can be standardized, thereby improving the problem of deviation in testing results when different users are changing testing operations.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
