Description
Water quality tester Technical Field
[0001] This application relates to the field of water quality analysis and testing, and in particular to a water quality testing instrument. Background Technology
[0002] Water quality testing is the process of analyzing and measuring various physical, chemical, and biological indicators in water bodies. Its purpose is to assess water quality, determine whether it meets specific usage standards, and monitor changes in water quality.
[0003] Currently, numerous water quality analysis devices exist on the market, employing diverse analytical methods, primarily encompassing electrode methods and colorimetric methods. Electrode methods are mainly used to measure total dissolved solids (TDS) in water, utilizing electrochemical principles for water quality analysis. When the electrode comes into contact with the water sample, the analyte in the water undergoes a chemical reaction or physical change on the electrode surface, generating electrical signals such as current, potential, or resistance. These signals are related to the concentration or properties of the analyte. Colorimetric methods, on the other hand, are often used to accurately determine specific chemical components and mineral ions in water, such as total chlorine, residual chlorine, total alkalinity, and total hardness. Based on the color of the solution itself, or the color produced after adding reagents, the concentration of the analyte in the solution is determined by comparing the depth of the color or measuring the absorption of light at a specific wavelength. These colorimetric objects can be fully reacted liquid reagents or reaction-completed test strips. Currently, water quality analyzers require additional tools for collecting water samples and cannot directly sample water within the analyzer itself. Technical issues

[0051] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.
[0052] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.
[0053] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.
[0054] Referring to Figures 1 to 9, a water quality analyzer according to a preferred embodiment of this application is illustrated. The water quality analyzer 1 is used to test a water sample. A test tablet reacts with the analyte in the water sample, causing the water sample to display different colors. This allows for rapid and accurate test results, avoiding errors from visual observation and ensuring the precision and consistency of the test results.
[0055] Figure 1 is a schematic diagram of the overall structure of the water quality analyzer 1 according to a first preferred embodiment of this application. In this embodiment, the water quality analyzer 1 includes a main body assembly 10, a mounting frame assembly 20, a control assembly 30, and a detection assembly 40. The mounting frame assembly 20 is disposed within the main body assembly 10. The control assembly 30 and the detection assembly 40 are both mounted on the mounting frame assembly 20. The water sample to be tested is adapted to be placed in the main body assembly 10. The control assembly 40 is adapted to control the detection assembly 40 to detect the water sample to be tested and display the detection result on the main body assembly 10.
[0056] Figure 2 is an exploded view of a water quality analyzer according to an embodiment of this application. The main body component 10 includes a housing portion 11, a storage portion 12, a display portion 13, and an internal region 14 located within the housing portion 11. The display portion 13 is disposed on the surface of the housing portion 11 to display the test results of the water sample to be tested. The mounting bracket assembly 20 is detachably installed within the internal region 14 of the housing portion 11. The storage portion 12 is placed within the mounting bracket assembly 20, and the water sample to be tested is placed in the storage portion 12. Then, the user controls the detection component 40 to test the water sample and display the test results on the display portion 13 via the control component 40. The water quality analyzer 1 can quickly provide test results, greatly shortening the testing time, improving testing efficiency, and meeting the needs of rapid testing.
[0057] The control component 30 includes a power supply 31 and a circuit board 32. The power supply 31 and the circuit board 32 are mounted on the mounting frame 20. The power supply 31 provides power to the water quality analyzer 1. The circuit board 32 is electrically connected to the detection component 30. The circuit board 32 is also equipped with a built-in program. After analysis and processing by the built-in program, accurate detection results can be quickly given.
[0058] Specifically, the detection component 40 includes an illumination light source 41 and a photodetector 42. The illumination light source 41 and the photodetector 42 are respectively disposed on both sides of the mounting bracket assembly 20 and close to the storage section 12 to facilitate the detection of the water sample to be tested within the storage section 12. Furthermore, the illumination light source 41 and the photodetector 42 are electrically connected to the control component 30, allowing the user to control the on / off state of the illumination light source 41 and the photodetector 42 via the control component 30.
[0059] More specifically, in the embodiments of this application, the illumination light source 41 is implemented as an ultra-high brightness white LED light source, and the photodetector 42 is implemented as a high-performance photodetector device. Within the housing 12, the detection tablet reacts with the analyte in the water sample, causing the water sample to exhibit different colors. Then, the water sample is illuminated by the ultra-high brightness white LED light source. The high-performance photodetector device accurately measures the wavelength of the light, and after analysis and processing by the built-in program, accurate detection results can be quickly provided, avoiding errors from visual observation and ensuring the accuracy and consistency of the test results. In other words, when the LED light source illuminates the water sample, specific light is absorbed by the water sample, and the degree of absorption is related to the liquid color. Therefore, after the illumination light source 41 illuminates the water sample, the photodetector 42 quickly obtains accurate detection results based on the RGB values of the water sample and a preset program algorithm.
[0060] In another possible implementation, a filter and a special diode are added to the illumination light source 41 and the photodetector 42, respectively. The filter can filter out interfering light and improve the purity of light at a specific wavelength, thereby improving measurement accuracy. The special diode can quickly respond to and lock onto light at a specific wavelength, greatly shortening the measurement time. Compared with traditional visual colorimetry and photoelectric colorimetry, our improved scheme not only solves the problems of errors caused by visual observation and external interference, but also overcomes the limitations of photoelectric colorimetry. Overall, this improvement makes water quality testing more intelligent and accurate, meeting the needs of modern water quality testing.
[0061] The mounting bracket assembly 20 includes a first mounting bracket 21 and a second mounting bracket 22, the first mounting bracket 21 being connected to the front end of the second mounting bracket 22, wherein the storage portion 12 is adapted to be placed on the first mounting bracket 21, and the control component 30 is mounted on the second mounting bracket 22.
[0062] The first fixing frame 21 includes a first fixing frame body 211 and a measuring chamber 212, the measuring chamber 212 being located within the first fixing frame body 211. In other words, the measuring chamber 212 extends downwardly from the surface of the first fixing frame body 211, and the receiving part 12 is adapted to be placed within the measuring chamber 212.
[0063] The second mounting bracket 22 includes a second mounting bracket body 221, a first battery cavity 222, and a second battery cavity 223. The first battery cavity 222 and the second battery cavity 223 are disposed on the second mounting bracket body 221. The first battery cavity 222 and the second battery cavity 223 are used to house the power supply 31. In the embodiments of this application, four AAA batteries are installed in the first battery cavity 222 and the second battery cavity 223 for power supply. That is, two AAA batteries are installed in the first battery cavity 222, and two AAA batteries are also installed in the second battery cavity 223.
[0064] It is worth mentioning that the fixing frame assembly 20 also includes a first mounting part 23 and a second mounting part 24. The first mounting part 23 and the second mounting part 24 are respectively disposed on both sides of the first fixing frame 21. The illumination light source 41 is mounted on the first mounting part 23, and the photoelectric receiver 42 is mounted on the second mounting part 24.
[0065] The first mounting portion 23 includes a first mounting unit 231, a first positioning post 232, and a first mounting cavity 233. The first mounting unit 231 is disposed on the right side of the first fixing frame 21, and the first mounting cavity 233 is disposed on the first mounting unit 231. Further, the first mounting cavity 233 extends inwardly from the surface of the first mounting unit 231 to mount the illumination light source 41. The first positioning post 232 is disposed on the surface of the first mounting unit 231.
[0066] The second mounting portion 24 includes a second mounting unit 241, a second positioning post 242, and a second mounting cavity 243. The second mounting unit 241 is disposed on the left side of the first fixing frame 21, and the second mounting cavity 243 is disposed on the second mounting unit 241. Furthermore, the second mounting cavity 243 extends inwardly from the surface of the second mounting unit 241 to mount the photoelectric receiver 42. The second positioning post 242 is disposed on the surface of the second mounting unit 241.
[0067] In embodiments of this application, the position of the first positioning post 232 relative to the first mounting unit 231 is different from the position of the second positioning post 242 relative to the second mounting unit 241. For example, the first positioning post 232 is located at the upper right corner of the first mounting unit 231, and the second positioning post 242 is located at the lower left corner of the second mounting unit 241. In another possible embodiment, the first positioning post 232 is located at the lower right corner of the first mounting unit 231, and the second positioning post 242 is located at the upper left corner of the second mounting unit 241. Those skilled in the art should understand that the positions of the first positioning post 232 relative to the first mounting unit 231 and the second positioning post 242 relative to the second mounting unit 241 are not limitations of this application. The first positioning post 232 and the second positioning post 242 are merely for differentiation to ensure correct installation of the illumination light source 41 and the photoelectric display 42, preventing them from being installed in reverse and affecting the detection results. In addition, the illumination light source 41 is installed in the first mounting cavity 233, and the photoelectric receiver 42 is installed in the second mounting cavity 243. The illumination light source 41 and the photoelectric display 42 can also block light to prevent external light from affecting the detection results and the accuracy of the detection.
[0068] The mounting bracket assembly 20 further includes a plurality of mounting posts 25, which are disposed on the surface of the second mounting bracket 22 and protrude upward from the surface of the second mounting bracket 22 for fixing the circuit board 32. Preferably, in this embodiment, the mounting posts 25 are disposed at the four corners of the second mounting bracket 22 to ensure the stability of the circuit board 42 when it is installed on the second mounting bracket 22.
[0069] The mounting bracket assembly 20 further includes two positioning crossbars 26, which are respectively disposed on both sides of the first mounting bracket 21 and protrude outward from the first mounting bracket 21. In this embodiment, the positioning crossbars 26 are used to better position the front end of the first mounting bracket 21, preventing deformation of the plastic part's front and rear length from affecting the detection accuracy, thus facilitating better fixation of the first mounting bracket 21 inside the housing portion 11 of the main body assembly 10. On the other hand, it helps to better fix the mounting bracket assembly 20 and the main body assembly 10, improving the sealing performance of the water quality analyzer 1.
[0070] The housing portion 11 includes a housing unit 111, a storage support portion 113, and a bucket storage chamber 112. The bucket storage chamber 112 is disposed within the housing unit 111. In this embodiment, the bucket storage chamber 112 is located at the front end of the housing unit 111 and extends downwardly from the front end surface of the housing unit 111 to form a cavity. The first fixing frame 21 is adapted to be placed within the bucket storage chamber 112. The measuring chamber 212 of the first fixing frame 21 communicates with the bucket storage chamber 112, and the storage portion 12 is adapted to be placed within the measuring chamber 212. The storage support portion 113 is integrally formed into the housing unit 111. The storage portion 12 is placed within the measuring chamber 212, and the storage portion 12 is supported by the storage support portion 113.
[0071] The housing unit 111 includes a placement and fixing member 1111, a first groove 1112 and two second grooves 1113. The placement and fixing member 1111 is disposed at the bottom of the housing unit 111. In this embodiment, the number of placement and fixing members 1111 is set to two. One placement and fixing member 1111 is semi-arc and is disposed at the front end of the bottom of the housing unit 111. The other placement and fixing member 1111 is straight and is disposed at the rear end of the bottom of the housing unit 111. When the water quality tester 1 is placed on the platform, the placement and fixing member 1111 plays a stabilizing role.
[0072] The first groove 1112 is disposed on the receiving part support 113. Specifically, the first groove 1112 extends downward from the surface of the receiving part support 113, forming a V-shaped groove. The first groove 1112 increases the bonding area, improves the bonding strength, and provides a waterproof effect. Furthermore, it allows the receiving part 12 to be better positioned in the center of the measuring chamber 212, improving detection accuracy. Specifically, the first groove 1112 significantly increases the bonding area. During bonding operations, the adhesive material can penetrate deep into the first groove 1112, greatly improving the stability and sealing of the receiving part support 113 and the receiving part 12. This large-area bonding method significantly improves the bonding strength. Moreover, this high-strength bonding effectively prevents moisture penetration, forming a robust waterproof barrier.
[0073] The storage support 113 extends horizontally from the outer shell toward the center of the storage chamber 112, so as to better place the storage bucket 121 at the center of the measuring chamber 212.
[0074] Two second grooves 1113 are provided on both sides of the housing unit 111. In other words, the two second grooves 1113 extend inward from both sides of the housing unit 111. Due to the wall thickness caused by the internal structure of the housing unit 111, there will be shrinkage marks on both sides of the housing unit 111. In order not to affect the appearance of the housing unit 111 and to reduce the shrinkage marks caused by the wall thickness, semi-circular long grooves are opened on both sides of the housing unit 111 to reduce the problem caused by the wall thickness.
[0075] The storage unit 12 includes a storage bucket 121 and a storage bucket lid 122. The storage bucket lid 122 is detachably installed on the storage bucket 121. The storage bucket 121 is adapted to be placed in the measuring chamber 212 of the first fixing frame 21 and supported by the storage unit support 113. The storage bucket 121 has a storage cavity 1211. The water sample to be tested is adapted to be placed in the storage cavity 1211. The test tablet reacts with the test substance in the water sample, causing the water sample to show a different color. Then, the water sample is irradiated by the illumination light source 41. The wavelength of the light is accurately measured by the photoelectric receiver 42. After analysis and processing by the built-in program, accurate test results can be quickly given, avoiding the error of visual observation and ensuring the accuracy and consistency of the test results.
[0076] In embodiments of this application, the storage container 121 is preferably configured as a transparent container, so that when the water sample to be tested is placed in the storage container 121, the illumination light source 41 can illuminate the water sample through the storage container 121. When the LED light source illuminates the water sample, specific light is absorbed by the water sample, and the degree of absorption is related to the liquid color. Therefore, when the illumination light source 41 illuminates the water sample, the photoelectric receiver 42 can quickly obtain an accurate detection result based on the RGB value of the water sample and a preset program algorithm.
[0077] The display unit 13 includes a display screen 131, a display screen mounting port 132, and a screen fixing slot 133. The display screen mounting port 132 is disposed in the housing unit 111 of the housing part 11. The display screen mounting port 132 extends downwardly from the surface of the housing unit 111 of the housing part 11 to communicate with the internal region 14. The display screen 131 is snapped into the display screen mounting port 132. The display screen 131 is used to display the test results of the water sample to be tested, which is convenient for users to observe. The water quality tester 1 is easy to operate and can be operated without complicated training, reducing the professional requirements for operators. The screen fixing slot 133 is soldered to the circuit board 32. By placing the display screen 131 in the screen fixing slot 133, it serves to fix the display screen 131, align the display screen mounting port 132, and protect the display screen 131.
[0078] It is worth mentioning that the housing part 11 further includes a housing button 114, which includes a master switch 1141, a switch item button 1142, and a test button 1143. The master switch 1141, the switch item button 1142, and the test button 1143 are all disposed on the surface of the housing unit 111 of the housing part 11. The master switch 1141 is used to control the water quality detector 1 to turn on and off. The switch item button 1142 is used to adjust the water quality detector 1 to zero so that the previous test result will not interfere with the next test result. The test button 1143 is used to control the illumination lamp source 41 and the photoelectric receiver 42 to turn on and off.

[0080] The main component 10 also includes a labeling unit 15, which is attached to the surface of the housing portion 11 and serves to transmit and guide information.
[0081] Specifically, in the embodiments of this application, the labeling unit 15 includes a first label 151 and a second label 152. The first label 151 is affixed to the housing button 114 and the display screen 131. The first label 151 can be used to indicate the operation steps, label the function and operation sequence of each button and switch, that is, label the main power button 1141, the item switching button 1142, and the test button 1143. On the other hand, it can also protect the housing button 114 and the display screen 131, greatly enhancing the sealing performance of the housing button 114 and the display screen 131, thereby giving the water quality analyzer 1 good sealing performance, facilitating the sampling of the water sample to be tested, and preventing the water sample to be tested from entering the water quality analyzer 1 and causing damage.
[0082] The second label 152 is affixed to the back of the housing portion 11. The second label 152 can indicate important information such as the name, brand, model, specifications, ingredients, and usage method of the water quality analyzer 1. In this embodiment, the area below the second label 152 is the injection point for the housing portion 11 during injection molding. To ensure the overall aesthetics of the housing portion 11, a rectangular groove is created at this location to attach the second label 152.
[0083] The main component 10 also includes a front shield 16 and a rear cover 17. The front shield 16 is disposed at the front end of the first fixing frame 21 of the fixing frame assembly 20 to shield the storage bucket 121 placed inside the measuring chamber 212, thereby preventing external light from interfering with the water sample to be tested inside the storage bucket 121 and improving the accuracy of the test results of the water quality analyzer 1.
[0084] The rear cover 17 is disposed at the rear of the housing portion 11. In other words, the rear cover 17 is used to seal the rear end of the housing portion 11, so that the fixing bracket assembly 20 and the detection assembly 40 disposed within the housing portion 11 can remain sealed, preventing the water sample to be tested from entering the water quality analyzer 1 and causing damage. Specifically, the rear cover 17 includes a rear cover body 171, a sealing ring 174, and a positive and negative electrode spring slot 172 and a sealing groove 173. The rear cover body 171 is disposed at the rear end of the housing portion 11. The positive and negative electrode spring slot 172 is disposed within the rear cover body 171 to install a battery positive and negative electrode spring corresponding to the power supply 31. The sealing groove 173 is disposed within the rear cover body 171 to install the sealing ring 174. The sealing groove 173 is implemented as a trapezoidal groove, and the sealing ring 174 is implemented as an O-ring, which facilitates installation and provides a better sealing effect, preventing the water sample to be tested from entering the water quality analyzer 1 and causing damage. The positive and negative electrode springs are installed on the fixing frame assembly 20 and located within the positive and negative electrode spring grooves 172.
[0085] Therefore, the water quality analyzer 1 has good sealing performance, which facilitates the sampling of the water sample to be tested and prevents the water sample from entering the water quality analyzer 1 and causing damage. In other words, the water quality analyzer 1 has good sealing performance, and the water quality analyzer 1 can be directly placed into the water sample to be tested for sampling, eliminating cumbersome sampling steps and making the operation convenient and quick.
[0086] The main body assembly 10 also includes a limiting part 18, which includes two upper baffles 181, two protrusions 182, and two insert nuts 183. The two upper baffles 181 protrude from the inner wall surface of the housing part 11, and the two protrusions 182 protrude from the inner wall surface of the housing part 11. The upper baffles 181 guide and limit the upper part of the fixing bracket assembly 20 when it is pushed into the housing part 11, while the protrusions 182 control the lower and lateral limiting of the fixing bracket assembly 20. In other words, when the rear cover 17 is removed, the fixing bracket assembly 20 is adapted to be inserted into the internal region 14 of the main body assembly 10 through the rear end of the housing part 11. The upper baffles 181 and the protrusions 182 both serve a limiting function, facilitating the installation of the fixing bracket assembly 20 at a predetermined position on the main body assembly 10. The insert nut 183 is provided on the protrusion 182 to facilitate better connection and fixation of the fixing bracket assembly 20 to the housing part 11, while the screws can be repeatedly removed without damaging the screw holes.
[0087] The detection method and detection principle of the water quality analyzer 1 are described below by way of example.
[0088] First, the water sample to be tested is placed into the storage cavity 1211 of the storage bucket 121. For example, the water sample to be tested can be injected into the storage cavity 1211 of the storage bucket 121 using a syringe. Preferably, in the embodiments of this application, since the water quality analyzer 1 has good sealing performance, the water quality analyzer 1 can be directly placed into the water sample to be tested for sampling, eliminating cumbersome sampling steps and making the operation convenient and quick.
[0089] The user then controls the activation and deactivation of the illumination light source 41 and the photoelectric receiver 42 via the housing button 114. Inside the storage cavity 1211 of the storage container 121, the test tablet reacts with the analyte in the water sample, causing the water sample to display different colors. The water sample is then illuminated by an ultra-high brightness white LED light source. A high-performance photoelectric receiver accurately measures the wavelength of the light, and the built-in program analyzes and processes the data to quickly provide accurate test results, avoiding errors from visual observation and ensuring the accuracy and consistency of the test results. In other words, when the LED light source illuminates the water sample, specific light is absorbed by the water sample, and the degree of absorption is related to the liquid color. Therefore, when the illumination light source 41 illuminates the water sample, the photoelectric receiver 42 quickly obtains accurate test results based on the RGB values of the water sample and a preset program algorithm.
[0090] In summary, the water quality analyzer 1 has excellent sealing properties, facilitating the sampling of the water sample to be tested and preventing damage caused by the water sample entering the analyzer 1. The analyzer 1 can be directly placed into the water sample for sampling, eliminating cumbersome sampling steps and making operation convenient and quick. Furthermore, the water quality analyzer 1 illuminates the water sample through the illumination light source 41, and then the photoelectric receiver 42 accurately measures the wavelength of the light and detects the color change of the water sample, avoiding errors from visual observation and ensuring the accuracy and consistency of the test results.
[0091] It is worth mentioning that during the installation of this water quality analyzer, the control component 30 and the detection component 40 are installed on the mounting bracket assembly 20, and then the mounting bracket assembly 20 is fixed inside the housing portion 11. Then, the rear cover 17 is sealed and installed on the housing portion 11. Next, the storage bucket 121 is installed, and then the storage bucket 121 is fixed to the housing portion 11 by the storage bucket cover 122. The water quality analyzer is then installed. After installation, the two sides of the mounting bracket assembly 20 are connected to the two sides of the housing portion 11, leaving a gap between the control component 30 and the detection component 40 and the housing portion 11. With this structural design, the water quality analyzer of this application is easy to assemble and has good waterproof performance. Preferably, the length of the rear cover 17 accounts for 12.5% to 25% of the total length of the water quality analyzer. More preferably, it is 20%. The length of the housing portion 11 accounts for 87.5% to 75% of the total length of the water quality analyzer. In this way, the housing 11 is designed for collecting water samples when placed in pool water, and it is also waterproof. Furthermore, the entire water quality analyzer can also be submerged in water for sampling.
[0092] It is worth mentioning that the housing part 11 is integrally molded. This improves the waterproof capability. Existing water quality testers use a combination of an upper shell and a lower shell, which is prone to water leakage at the joint, making it unsuitable for waterproofing. The housing part 11 and the rear cover 17 are used for installation. The housing part 11 houses the entire mounting frame assembly 20. When the housing part 11 is placed in the pool water, its integral molding provides strong waterproof capability. Furthermore, the upper part of the storage tank 121 has an outwardly extending support ring. This support ring is supported by the storage part support 113 to fix and support the storage tank 122. When the storage tank 122 is filled with collected water, the weight of the storage tank 121 increases, increasing the pressure on the support ring and further tightening the storage part support 113 to increase sealing. This improves the waterproof performance of the water quality tester of this application. The first groove 1112 is provided in the storage support part 113 to prevent water from directly entering the storage cavity 112, thereby further improving the waterproof performance.
[0093] When using this water quality tester, the user can hold the rear of the housing 11 and the rear cover 17 and place the housing 11 into the swimming pool. Water from the pool enters the collection tank 121 through the collection tank lid 122 to collect the pool water. The first label 151 affixed above the housing buttons 114 and the display screen 131 is waterproof, preventing water from entering the water quality tester from the display screen 131 and the housing buttons 114. The rear cover 17 is waterproofed by a sealing ring 174, thereby improving the overall waterproof effect.
[0094] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The purpose of this application has been fully and effectively achieved. The functions and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
