Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] With the development of technology, various harmful gases are present in the air, some of which seriously endanger people's health. The extensive use of vehicles also emits various gases, and garbage incineration contributes to air pollution. Furthermore, formaldehyde is present in people's living environments. Formaldehyde is generally detected using methods such as spectrophotometry. Spectrophotometric detection modules for air quality testing are tools that help us detect and analyze various harmful gases in the air in real time, thereby enabling us to take appropriate measures to protect the environment and human health. The spectrophotometric detection module for air quality testing provided by this invention measures the formaldehyde content by detecting air. During the detection process, a filter screen can be used to filter the air entering the spectrophotometric detection module body 4, avoiding the problem of inaccurate detection results due to excessive dust in the air.
[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a spectrophotometer for air detection, including a housing 1, an installation plate 3 installed inside the housing 1, a spectrophotometer body 4 installed through the top of the installation plate 3, a connecting pipe 9 provided at the bottom of the spectrophotometer body 4, the connecting pipe 9 passing through the top of the installation plate 3, a connector 10 screwed to the top of the connecting pipe 9, a first connecting shell 11 fixed to the top of the connector 10, a second connecting shell 14 screwed to the top of the first connecting shell 11, an installation pipe 15 fixed to the top of the second connecting shell 14, a limiting plate 12 fixed to the inner wall of both the first connecting shell 11 and the second connecting shell 14, a filter frame 13 inserted between the two limiting plates 12, a plurality of filter screens installed inside the filter frame 13, the filter screens having progressively smaller apertures from top to bottom, and an installation cover 16 screwed to the top of the installation pipe 15.
[0021] It is important to note that by setting up a filter screen to filter dust and other particles in the air, it is possible to prevent a large amount of dust from entering the spectrophotometer detection module body 4 through the connecting tube 9, which could lead to inaccurate detection results. In addition, when a lot of dust accumulates on the filter screen, the filter frame 13 can be removed by rotating the second connecting shell 14 off the first connecting shell 11, making it convenient to clean the filter screen. Furthermore, when not in use, the mounting cover 16 can be used to cover the mounting tube 15 to prevent dust from entering the mounting tube 15.
[0022] like Figure 2 As shown, a storage box 6 is fixed to the top of the mounting plate 3. An extension tube 7 is placed inside the storage box 6. A fixing piece is fixed to one end of the extension tube 7, and the fixing piece is screwed to the mounting tube 15. A strap is installed on the outer wall of the storage box 6, and a limit block is fixed to one end of the storage box 6. The limit block is inserted into the strap. An air pump is installed at the bottom of the mounting plate 3. The air inlet of the air pump is fixedly connected to the connecting pipe 9, and the air outlet of the air pump is connected to the spectrophotometer detection module body 4.
[0023] It should be noted that the extension tube 7 is stored in the storage box 6. The extension tube 7 is connected to the mounting tube 15 through the fastener. The extension tube 7 facilitates the collection of air from different locations for detection. The outside air is drawn in by the air pump and then detected by the spectrophotometer detection module 4.
[0024] like Figure 2 As shown, a printer 5 is installed through the top of the mounting plate 3, a battery is installed at the bottom of the mounting plate 3, and a socket 8 is installed through the top of the mounting plate 3. A display screen is installed at the top of the spectrophotometer detection module body 4. A cover 2 is installed at the top of the housing 1, and a collection slot 17 is opened on one side of the housing 1, in which a tripod 18 is placed. A door is installed on one side of the housing 1, and both the cover 2 and the door are connected to the housing 1 by snap-fit. The door is located on one side of the collection slot 17. Multiple support legs 19 are fixed at the bottom of the housing 1, which facilitates the placement of the device in a designated position. In addition, the tripod 18 makes the positioning of the spectrophotometer detection module more flexible. Users can easily adjust the angle and height of the module as needed, which is very important for accurately measuring the gas concentration in a specific area or air. The tripod 18 is generally lightweight and easy to carry and move. When conducting tests at multiple monitoring points, users can easily move the detection module from one place to another without resetting the equipment or performing cumbersome calibration operations.
[0025] It should be noted that printer 5 can print out the detection results. The socket 8 is set up to facilitate the charging of the battery. The battery powers the spectrophotometer module 4, the air pump and printer 5. The collection slot 17 is set up to facilitate the storage of the tripod 18. The specific connection methods and working principles of the multiple electrical components are well known in the field and will not be described in detail here.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
