Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, specifically a simple device for water quality testing. Background Technology

[0002] Humans cannot live without water, and the quality of drinking water is closely related to human health. As people's demands for drinking water quality continue to rise, drinking water quality standards are also constantly developing and improving. Because the formulation of drinking water quality standards is related to various factors such as people's living habits, culture, economic conditions, the level of scientific and technological development, and the current state of water resources and their quality, the requirements for drinking water quality vary.

[0003] Water quality testing is crucial in environmental monitoring, drinking water safety, and industrial production. However, existing professional testing equipment is bulky and complex, requiring specialized personnel to operate, making it difficult to conduct rapid testing in fields and remote areas. While small portable testing devices are convenient to carry, they often lack a stable sampling structure during water sample collection, resulting in unrepresentative water samples that affect the accuracy of test results. Furthermore, impurities in the water can easily clog the sampling channel. Additionally, when testing, water is dripped onto test paper for observation, and only the part of the test paper in contact with the water droplet reacts, which may result in insufficient adsorption and reaction of various components in the water sample. Moreover, most simple testing devices place the various testing components in a scattered manner, making them inconvenient to store and carry. Therefore, this utility model provides a simple device for water quality testing. Utility Model Content

[0013] Beneficial effects

[0014] This invention provides a simple device for water quality testing. Compared with the prior art, it has the following advantages:

[0015] Firstly, in the testing process of this invention, the water source to be tested is placed in the test tube body. Then, the first clamping plate is pulled by the pull rod, and compressed against the inner wall of the fixing block by the positioning rod and spring. The first clamping plate then moves away from the second clamping plate. One end of the pH test paper is placed between the clamping plates. The pull rod is released, allowing the teeth and grooves between the clamping plates to fix the pH test paper. Finally, the threaded cap is threaded onto the upper end of the test tube body. The test tube is gently shaken to bring the water source into contact with the test paper. The results are then compared and observed using a colorimetric card, thus completing the testing process. Simultaneously, shaking the test tube allows for better mixing of the water source and the pH test paper. The shaking allows for more thorough contact and reaction, avoiding inaccurate results due to localized concentration differences. Simultaneously, better mixing of the water sample ensures a more uniform distribution of components, making the test results more representative of the overall pH level and improving accuracy and reliability. The shaking also promotes material exchange between the water sample and the test strip, allowing the reaction to reach equilibrium more quickly and enabling the test strip to display a stable color faster, thus shortening testing time and increasing efficiency. Furthermore, the shaking of the test tube eliminates the need for additional complex equipment or procedures, achieving sufficient contact and mixing between the water sample and the test strip, facilitating rapid water quality testing in various scenarios.

[0016] Secondly, the counterweight in this invention ensures the stability of the connecting hose in the water, preventing displacement due to water flow impact or shaking. This guarantees that each sample is taken at the preset position, ensuring representativeness and improving the accuracy of the test results. Simultaneously, the filter effectively removes impurities such as leaves, sediment, and plankton, preventing them from entering the syringe body and affecting the subsequent reaction between the pH test strip and the water sample. It also prevents impurities from clogging the connecting hose and syringe body, ensuring smooth sampling and extending the device's lifespan. Finally, the syringe body is conveniently housed in a carrying case for easy transport of the entire simple water quality testing device. When not in use, the connecting hose, counterweight, filter, and syringe body are stored together as a single unit, saving space, preventing component loss, and facilitating future use.

[0026] The testing component includes a support ring 4 fixed to the inner wall of the main body 1 of the carrying case, a test tube body 401 inserted inside the support ring 4, a threaded cap 402 threaded on the outer wall of the top of the test tube body 401, and a clamping component for fixing the test paper at the lower end of the threaded cap 402.

[0027] The installation components include a test strip shell 7 fixed inside the main body 1 of the carrying case. Inside the test strip shell 7 is a pressure plate 704 connected by a threaded assembly. Inside the main body 1 is a syringe body 6 for sampling. A connecting hose 601 is fixed to one end of the syringe body 6. A counterweight 602 is fixed to the outer wall of the front end of the connecting hose 601. A filter screen 603 is fixed to the input end of the connecting hose 601. Opening the cover 2 of the main body 1, the syringe body 6 is removed. The connecting hose 601 is inserted into the water source to be tested. Because the counterweight 602 is fixed to the outer wall of the front end of the connecting hose 601, it allows the connecting hose 601 to sink more stably in the water, maintaining a suitable water sampling position. Pushing the piston of the syringe body 6 expels internal air. Slowly pulling the piston, under negative pressure, the water source passes through the connecting hose 601, and after passing through the filter screen 603 to remove larger impurities and suspended solids, enters the syringe body 6, completing the water sample collection. The syringe body 6 has a volume of... Compact and easy to hold, this device, equipped with a connecting hose 601, allows for sampling in water at different depths and locations. Whether it's a shallow puddle or a deep river or lake, it can flexibly obtain water samples, improving the convenience and applicability of sampling. The counterweight 602 ensures the stability of the connecting hose 601 in the water, preventing displacement due to water flow or shaking. This ensures that each sampling is performed at the preset location, guaranteeing the representativeness of the water sample and improving the accuracy of the test results. Meanwhile, the filter 603 effectively filters out impurities in the water, such as leaves, silt, and plankton, preventing these impurities from entering the syringe body 6 and affecting the subsequent reaction between the pH test strip and the water sample. It also prevents impurities from clogging the connecting hose 601 and the syringe body 6, ensuring a smooth sampling process and extending the device's lifespan. Finally, the syringe body 6 is placed in the carrying case 1 for easy transport of the entire simple water quality testing device. When not in use, the connecting hose 601, counterweight 602, and filter 603 are integrated with the syringe body 6 and stored together as a whole, saving space and preventing parts from being lost, making it convenient for the next use.

[0028] In a preferred embodiment, the upper end of the carrying case body 1 is provided with a cover plate 2 rotatably connected via a rotating shaft. A carrying ring 201 is fixed to the upper end of the cover plate 2, and a snap fastener 202 is fixed to the front end of the cover plate 2, making it convenient for users to carry the device. Whether for short-distance movement or long-distance carrying, it can provide a stable grip point, making it easy to take the device to different testing locations, such as rivers, lakes, wells, and other places where water quality needs to be tested. The carrying case structure can store all the items needed for testing in a relatively independent space, avoiding the scattering and loss of parts, making it easy for users to quickly find and retrieve the required items when needed, improving testing efficiency. At the same time, the overall carrying case design also allows the device to be conveniently stored when not in use, without taking up too much space, allowing users to easily carry it to different places for water quality testing.

[0029] In a preferred embodiment, the inner wall of the cover plate 2 is provided with a colorimetric card 3 for observing water quality testing. Three sets of pressure rings 301 are fixed to the inner wall of the cover plate 2 to press down on the installed threaded cap 402, preventing loosening during transport. The colorimetric card 3 works by using the color produced by the reaction of a standard solution with a known pH value and an acid-base indicator as a reference standard. In water quality testing, pH test paper soaked in the water sample is compared with the colorimetric card 3. Because water samples with different pH values ​​will cause the acid-base indicator on the pH test paper to show different colors... By comparing the pH value of the water sample with the standard color on the colorimetric card 3, the pH range of the water sample can be determined, thus understanding the acidity or alkalinity of the water. The colorimetric card 3 is placed on the inner wall of the cover plate 2. When the device is opened for water quality testing, the colorimetric card 3 is right in front of you. Users can easily place the pH test strip and the colorimetric card 3 together for comparison and observation without having to search for or look for the colorimetric card 3 separately, which improves the efficiency and convenience of the test. The colorimetric card 3 is integrated into the structure of the device itself, eliminating the need to set aside a separate storage space for the colorimetric card 3, making the entire water quality testing device more compact, easy to carry and store.

[0030] In a preferred embodiment, the clamping assembly includes a fixing block 5 fixed to the lower end of the threaded cap 402, a spring 503 fixed to the inner wall of the fixing block 5, a first clamping plate 502 fixed to the end of the spring 503, four sets of positioning rods 501 fixed to the side wall of the first clamping plate 502, the positioning rods 501 being slidably connected to the fixing block 5, and a second clamping plate 504 fixed to the front end of the clamping face of the first clamping plate 502 at the lower end of the threaded cap 402, the clamping surface of the second clamping plate 504 having evenly spaced toothed grooves. The clamping surface of the first clamping plate 502 is uniformly fixed with toothed blocks that mesh with the toothed grooves. During testing, the test tube body 401 is placed with the water source to be tested. Then, the first clamping plate 502 is pulled by the pull rod, compressing it against the inner wall of the fixing block 5 through the positioning rod 501 and the spring 503. Then, the first clamping plate 502 moves away from the second clamping plate 504, and one end of the pH test paper is placed between the clamping plates. The pull rod is then released, allowing the toothed blocks and grooves between the clamping plates to fix the pH test paper. Then, thread the cap 402 to the upper end of the test tube body 401. Gently shake the test tube to bring the water source into contact with the test paper, and then compare and observe using the colorimetric card 3 to complete the detection. At the same time, shaking the test tube can better mix the water source. Shaking the test tube allows the water source and pH test paper to fully contact and react more fully, avoiding inaccurate test results due to local concentration differences. In addition, better mixing of the water source can make the various components in the water sample more evenly distributed, making the test results more representative of the overall acidity and alkalinity of the water sample, improving the accuracy and reliability of the test. Shaking promotes the exchange of substances between the water sample and the test paper, allowing the reaction to reach equilibrium more quickly, and allowing the test paper to show a stable color more quickly, thereby shortening the detection time and improving the detection efficiency. Moreover, by shaking the test tube, the water source and test paper can be fully contacted and mixed without additional complicated equipment or operating steps, making it convenient for users to quickly conduct water quality tests in different scenarios.

[0031] In a preferred embodiment, the threaded assembly includes a baffle 701 fixed at the center of the test strip housing 7. A groove 702 is provided at the center of the baffle 701. A pressure plate 704 is slidably connected to the inner wall of the groove 702. A screw 703 is rotatably connected to the groove 702 in the vertical direction. The screw 703 is threadedly connected to the pressure plate 704. The test strip housing 7 is used to hold pH test strips. Then, by rotating the screw 703, the pressure plate 704 slides downward along the groove 702, clamping and fixing the test strip inside the carrying case. Placing the test strip in the test strip housing 7 inside the carrying case makes it easy for users to quickly find the test strip when water quality testing is needed. The test strips are neatly stored in a specific position and will not be scattered messily in the carrying case, improving the efficiency of retrieving the test strips and making the testing process more convenient and smooth. It can prevent the test strips from being squeezed and rubbed against other testing tools or items in the carrying case, effectively preventing the test strips from being broken or torn, and extending the service life of the test strips.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] During operation, open the cover 2 of the carrying case body 1, take out the syringe body 6, and insert the connecting hose 601 into the water source to be tested. Because a counterweight 602 is fixed to the outer wall of the front end of the connecting hose 601, the counterweight 602 allows the connecting hose 601 to sink more stably in the water, maintaining a suitable water sampling position. Push the piston of the syringe body 6 to expel internal air, and then slowly pull the piston. Under negative pressure, the water source passes through the connecting hose 601, and after being filtered by the filter screen 603 to remove larger impurities and suspended solids, enters the syringe body 6, completing the water sample collection. The source is injected into the test tube. The test tube body 401 is placed with the water source to be tested. Then, the first clamp 502 is pulled by the pull rod and compressed on the inner wall of the fixing block 5 through the positioning rod 501 and the spring 503. Then, the first clamp 502 moves away from the second clamp 504. One end of the pH test paper is placed between the clamps. The pull rod is released so that the teeth and grooves between the clamps fix the pH test paper. Finally, the threaded cap 402 is threaded onto the upper end of the test tube body 401. The test tube is gently shaken to bring the water source into contact with the test paper. Then, the colorimetric card 3 is used for comparison and observation to complete the detection work.

[0034] The test strip housing 7 is designed to hold pH test strips. Then, by rotating the screw 703, the pressure plate 704 slides down along the slide groove 702 to clamp and fix the test strip inside the carrying case. The test strip is placed in the test strip housing 7 inside the carrying case, making it easy for users to quickly find the test strip when water quality testing is needed. The test strip is neatly stored in a specific location and will not be scattered messily inside the carrying case, thus improving the efficiency of retrieving the test strip.
