Description

Technical Field

[0001] This utility model specifically relates to a rapid water quality testing device. Background Technology

[0002] Current rapid water quality testing primarily involves squeezing water samples into a test bag containing reagents, allowing them to react for a period of time, and then performing a rough determination by comparing the results to a color chart. The tested indicators are conventional, such as COD. mn (i.e., permanganate index), ammonia nitrogen, and total phosphorus.

[0003] However, the existing water quality testing equipment is relatively loose and inconvenient to operate. Each analysis requires three test strips. Currently, the main indicators for water quality testing are permanganate index, ammonia nitrogen, and total phosphorus. These three indicators need to be measured simultaneously, which is cumbersome and affects the testing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a rapid water quality testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water quality rapid testing device, comprising a housing, wherein a CODmn monitoring window, an ammonia nitrogen monitoring window and a total phosphorus monitoring window are sequentially provided on the front of the housing from left to right, and a receiving cavity is provided inside the housing and located on one side of the total phosphorus monitoring window, wherein a total phosphorus indicator is placed in the receiving cavity.

[0006] Preferably, test strips are inserted into the CODmn monitoring window, ammonia nitrogen monitoring window, and total phosphorus monitoring window, and a limiting groove for fixing the test strips is provided on the lower surface of the CODmn monitoring window, ammonia nitrogen monitoring window, and total phosphorus monitoring window.

[0007] Preferably, the upper surface of the housing has a slot for inserting test strips, located vertically above the CODmn monitoring window, the ammonia nitrogen monitoring window, and the total phosphorus monitoring window.

[0008] Preferably, the housing contains three cavities corresponding to the CODmn monitoring window, the ammonia nitrogen monitoring window, and the total phosphorus monitoring window, and each of the three cavities contains a test strip corresponding to CODmn, ammonia nitrogen, and total phosphorus.

[0009] Preferably, the upper surfaces of the three cavities are all connected to a cover plate by hinges.

[0010] Preferably, a groove for placing a plastic dropper is provided on the front of the housing, on one side of the total phosphorus monitoring window.

[0011] Preferably, a heating element is provided inside the housing and at the bottom of the CODmn monitoring window, ammonia nitrogen monitoring window and total phosphorus monitoring window, and a power supply for power supply is provided on the back of the housing.

[0012] The technical effects and advantages of this utility model are as follows: First, the cover plate on the surface of the cavity is opened using a hinge. Test strips corresponding to CODmn, ammonia nitrogen, and total phosphorus are taken out and inserted into the corresponding monitoring windows. Then, water samples and indicator reagents are dropped into the test strips. After a period of time, the color change is observed through the monitoring window to roughly determine the data for these three indicators. When the temperature is low, heating can be used to accelerate the reaction time. During use, a power supply is installed in advance, and the three indicators are integrated into one device. It is portable, easy to operate, and allows for a convenient and intuitive overall assessment of water quality. The temperature can be adjusted to accelerate the reaction time and improve work efficiency. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] For portability and ease of operation, please refer to... Figure 1 , Figure 2 and Figure 3As shown, the device includes a housing 1. From left to right, the front of the housing 1 has a CODmn monitoring window 2, an ammonia nitrogen monitoring window 3, and a total phosphorus monitoring window 4. Inside the housing 1, and on one side of the total phosphorus monitoring window 4, is a receiving cavity 5 containing a total phosphorus indicator. First, open the cover 10 on the surface of the cavity 9 using a hinge. Take out the test strip 6 corresponding to CODmn, ammonia nitrogen, and total phosphorus, insert it into the corresponding monitoring window, and then drop the water sample and indicator into the test strip 6. After a period of time, observe the color change through the monitoring window to roughly determine the data for these three indicators. When the temperature is low, heating can be achieved using a heating element 13 to accelerate the reaction time. During use, a power supply 14 should be installed beforehand, concentrating the three indicators into one device. It is portable, easy to operate, and allows for a convenient and intuitive overall assessment of water quality.

[0020] To speed up the reaction time, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, test strips 6 are inserted into the CODmn monitoring window 2, ammonia nitrogen monitoring window 3, and total phosphorus monitoring window 4. A limiting groove 7 for fixing the test strip 6 is formed on the lower surface of each of these windows. When the test strip 6 is inserted into the CODmn monitoring window 2, ammonia nitrogen monitoring window 3, and total phosphorus monitoring window 4, it is fixed in the limiting groove 7, ensuring the stability of the test strip 6 during testing. A slot 8 for inserting the test strip 6 is formed on the upper surface of the housing 1, vertically above the CODmn monitoring window 2, ammonia nitrogen monitoring window 3, and total phosphorus monitoring window 4. The test strip 6 can be inserted into the CODmn monitoring window 2, ammonia nitrogen monitoring window 3, and total phosphorus monitoring window 4 through the slot 8. Inside the housing 1, three cavities 9 are respectively formed at locations corresponding to the CODmn monitoring window 2, ammonia nitrogen monitoring window 3, and total phosphorus monitoring window 4. Each of the three cavities 9 contains three different test strips 6 corresponding to CODmn, ammonia nitrogen, and total phosphorus. The cavities 9 can carry three different test strips 6, allowing simultaneous testing of CODmn, ammonia nitrogen, and total phosphorus, improving overall convenience. Each of the three cavities 9 has a cover plate 10 connected to its upper surface by a hinge. Opening the cover plate 10 by rotating the hinge allows the test strips 6 to be removed from the cavity 9. On the front of the housing 1, next to the total phosphorus monitoring window 4, there are two grooves 12 for placing plastic droppers 11, allowing for the simultaneous placement of two plastic droppers 11, further enhancing overall practicality and convenience. Heating elements 13 are installed inside the housing 1, at the bottom of the CODmn monitoring window 2, ammonia nitrogen monitoring window 3, and total phosphorus monitoring window 4. A power supply 14 is located on the back of the housing 1. Heating can be applied when necessary, such as at low temperatures, to accelerate the reaction time; however, heating is generally not frequently used. The device must be charged or have batteries installed before use.

[0021] When using, first open the cover plate 10 on the surface of cavity 9 using the hinge, take out the test paper 6 corresponding to CODmn, ammonia nitrogen and total phosphorus, insert it into the corresponding monitoring window, then drop the water sample and indicator into the test paper 6, and after a period of time, observe the color change through the monitoring window to roughly judge the data of these three indicators. When the temperature is low, it can be heated by the heating element 13 to speed up the reaction time. When using, install the power supply 14 in advance and concentrate the three indicators on one device.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
