Description

Technical Field

[0001] The present invention relates to the field of water quality detection, and more particularly to a handheld water quality detector. Background Art

[0002] A handheld water quality tester is a portable instrument that integrates multiple online or on-site water quality parameter measurement functions. It is often used in scenarios such as environmental monitoring, drinking water safety, online detection of industrial emissions, and agricultural irrigation water quality monitoring.

[0003] In order to achieve rapid detection of water quality, the existing technology (Chinese utility model patent with announcement number CN214953453U) discloses a multifunctional handheld water quality detector, whose detection method is to directly inject the water sample to be tested into the water inlet of the instrument for detection. This detection method will make it inconvenient to clean the inside of the water inlet of the instrument. There are also some detectors in the existing technology that first put the water sample to be tested into a test tube, and then insert the test tube into the instrument for detection. This intubation type detector only needs to clean the test tube, which is more convenient to clean. However, when using a test tube to sample water outdoors, liquid, impurities and fingerprints will adhere to the outer surface of the test tube. Even after the outer surface of the test tube is cleaned manually, there will still be residual water marks on the outer surface of the test tube. The residual water marks will change the optical transmittance, causing the transmittance of the measurement band to deviate, resulting in unstable absorbance readings, which affects the detection accuracy.

This gradual contact avoids sudden high impact force and reduces the risk of scratches caused by the abrupt pressing of the bristles. At the same time, it can perform a deeper peeling of stubborn water spots and mineral deposits. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 13 A handheld water quality detector includes a housing 1, a slot 5 provided inside the housing 1, a detection light source 6 fixed to the inner wall of the slot 5, and a light source receiving portion 8.

[0023] The liquid supply assembly includes a micro pump body 79 fixedly connected to the inside of the shell 1 and the output end of which is connected to the flow channel of the hollow ring body 71, and a water storage box 80 located inside the shell 1. The input end of the micro pump body 79 is connected to the output end of the water storage box 80. A groove body for accommodating the water storage box 80 is opened on one side of the shell 1, and the water storage box 80 is clamped in the groove body.

[0024] The driving part includes a tooth key 2 77 integrally formed on the outer surface of the hollow rotating ring 1 72, a gear 1 76 rotatably connected to the inside of the shell 1 and meshing with the tooth key 2 77, a servo motor 1 75 fixed to the inside of the shell 1, a heat conducting part 1 78 fixed to one side of the outer surface of the servo motor 1 75 and extending outward through the shell 1, and the output shaft of the servo motor 1 75 is fixed to one side of the gear 1 76.

[0025] A display touch part 2 is also fixedly connected to one side of the shell 1, and an energy storage part 11 and a circuit board 12 are also fixedly connected inside the shell 1. The circuit board 12 is electrically connected to the energy storage part 11, the display touch part 2, the detection light source 6, the light source receiving part 8, and the anti-scattering processing component 7.

[0026] A protective cover 3 is rotatably connected to one side of the housing 1 , and the protective cover 3 is disposed outside the slot 5 . A charging unit 4 is fixedly connected to one side of the housing 1 , and the charging unit 4 is electrically connected to the energy storage unit 11 .

[0027] By adopting the above technical solution, the protective cover 3 is rotated to expose the slot 5, and the anti-scattering processing component 7 is controlled by the display touch part 2. The test tube containing the water sample to be tested is slowly inserted into the slot 5. When the test tube moves downward in the slot 5, the test tube first passes through the hollow ring body 71. The micro pump body 79 can pump the cleaning liquid (deionized water or low-concentration surfactant solution) in the water storage box 80 into the flow channel in the hollow ring body 71. The cleaning liquid enters the nozzle 711 from the flow channel and is discharged from the nozzle 711, spraying a trace amount of solution onto the outer surface of the test tube. Liquid moves downward through the test tube of the hollow ring body 71 to the inside of the hollow rotating ring 72, and the servo motor 75 drives the gear 76 to rotate, and the rotation of the gear 76 drives the hollow rotating ring 72 to rotate. The cleaning brush 73 on the inner wall of the hollow rotating ring 72 can generate physical shear force on the water droplets and water marks attached to the outer surface of the glass test tube, directly removing the liquid film and trace particles from the surface of the test tube. The polishing brush 74 on the inner wall of the hollow rotating ring 72 performs a secondary "polishing" wipe on the tube wall, further removing fine water marks and fine hair debris, which can effectively remove The outer surface of the test tube is free of water marks, which can prevent the optical transmittance from being affected by the water marks and change, reduce the deviation and stabilize the absorbance reading, and improve the detection accuracy. The test tube passing through the hollow swivel 72 continues to move downward and is inserted into the two sealing rings 52. The sealing rings 52 are made of rubber. The inner wall of the sealing ring 52 contacts the outer surface of the test tube. First, it can play a sealing effect to prevent the liquid on the outer surface of the test tube from flowing to the bottom of the slot 5. Second, it can scrape off the cleaned substances and liquids on the outer surface of the test tube. The substances flow into the drainage cavity 53 from the opening 51 along with the liquid. The liquid is discharged from the discharge port of the discharge cavity 53, and the test tube continues to move downward through the two sealing rings 52 until it reaches the bottom of the slot 5 and cannot move anymore. The detection light source 6 and the light source receiving part 8 are controlled by the display touch part 2. The detection light source 6 emits light of a specific wavelength (such as ultraviolet light, visible light) through the water sample in the test tube. The light source receiving part 8 (photoelectric sensor) detects the intensity change of the transmitted light or scattered light and feeds back the result to the circuit board 12. The display touch part 2 can display the detection data. The above-mentioned light source detection is a mature detection technology and will not be repeated here.

[0028] like Figures 9-11 As shown, the interior of the hollow rotating ring 72 is also connected to multiple deep cleaning components 9, and the deep cleaning components 9 include a rotating column 91 rotatably connected to the interior of the hollow rotating ring 72, a gear 92 fixed to one end of the rotating column 91, a disk 93 connected to the other end of the rotating column 91, and multiple cleaning brushes 94 fixed to one side of the disk 93 and extending into the slot 5. A movable groove 54 connected to the slot 5 is provided inside the shell 1, and a tooth key 56 is provided on the inner wall of the movable groove 54. The gear 92 is located in the movable groove 54 and the gear 92 is meshed with the tooth key 56.

[0029] By adopting the above technical solution, when the hollow rotating ring 1 72 rotates, it can drive multiple rotating columns 91 to rotate. When the multiple rotating columns 91 rotate, gear 2 92 will contact the tooth key 1 56. The tooth key 1 56 drives gear 2 92 and rotating column 91 to rotate. The rotating column 91 rotates inside the hollow rotating ring 1 72. When the rotating column 91 rotates, it drives the disk 93 and the cleaning brush 2 94 to rotate. The cleaning brush 2 94 is in vertical contact with the surface of the test tube, and forms tangential friction during rotation. The generated frictional shear force can peel off attached water droplets, water marks, microparticles and even biofilms in the radial direction, thereby improving the peeling effect on stubborn water marks.

[0030] like Figures 9-12 As shown, a plurality of arc-shaped flanges 55 are fixedly connected to the inner wall of the movable groove 1 54, and a movable rod 95 is movably inserted into the internal of the rotating column 91 and the gear 2 92, and one end of the movable rod 95 is fixedly connected to one side of the disk body 93, and the other end of the movable rod 95 extends into the movable groove 1 54, and the other end is rotatably connected to the ball 96, and a movable groove 2 97 is opened inside the rotating column 91, and a reset plate 98 and a spring 99 are provided in the movable groove 2 97, and the reset plate 98 is fixed to the outside of the movable rod 95, and the two ends of the spring 99 are respectively connected to the inner wall of the movable groove 2 97 and one side of the reset plate 98, and a plurality of guide bars 951 are fixed to the outer surface of the movable rod 95, and a plurality of guide grooves for respectively accommodating a plurality of guide bars 951 are opened inside the rotating column 91.

[0031] By adopting the above technical solution, when gear 2 92 moves in movable groove 1 54, ball 96 contacts arc flange 55, arc flange 55 pushes ball 96 and movable rod 95 to move, movable rod 95 moves inside rotating column 91 and drives disk 93 and cleaning brush 2 94 to move toward the test tube, so that cleaning brush 2 94 can gradually advance from "lightly touching the test tube" to "applying a certain pressure to the surface of the test tube". This progressive contact avoids sudden high impact force and reduces the risk of scratches caused by abrupt pressing of bristles. At the same time, it can also perform deeper peeling of stubborn water spots and mineral deposits.

[0032] like Figure 5 、 Figure 7 and Figure 13As shown, a pretreatment component 10 is also connected to the inside of the shell 1, and the pretreatment component 10 includes an air ring 101 fixed to the inside of the shell 1, a hollow rotating ring 102 rotatably connected to the inside of the shell 1 and rotatably connected to the upper end of the air ring 101, an annular cavity 110 opened in the inside of the hollow rotating ring 102 and connected to the air outlet of the air ring 101, a plurality of air outlets 103 opened in the inside of the hollow rotating ring 102 and connected to the annular cavity 110, a dynamic sealing part 104 connected to the connecting end face of the air ring 101 and the hollow rotating ring 102 (gas dynamic sealing technology is a mature existing technology, and in this application, a magnetic fluid sealing method can be selected for end face dynamic sealing, which will not be repeated here), a micro air pump 109 fixed to the inside of the shell 1 and the output end is connected to the input end of the air ring 101, and the input end of the micro air pump 109 extends outward through the shell 1, and the inner wall of the slot 5 is provided with an annular groove 57 for exposing the multiple air outlets 103.

[0033] The air ring 101 includes an annular body rotatably connected to the inside of the shell 1, a cavity opened inside the annular body, a plurality of alternating partitions 105 fixed to the inner wall of the cavity, an input port opened on one side of the annular body and connected to the cavity, and an annular exhaust port opened at the upper end of the annular body, and the annular exhaust port is connected to the annular cavity 110.

[0034] A gear three 107 is rotatably connected inside the shell 1. A servo motor two 106 is also fixed inside the shell 1, and the output shaft of the servo motor two 106 is fixed to the gear three 107. The outer surface of the hollow rotating ring two 102 is provided with a tooth key three 108 that meshes with the gear three 107. A heat conducting part two 111 is fixed to one side of the outer surface of the servo motor two 106, and the heat conducting part two 111 passes through the shell 1 and extends outward.

[0035] By adopting the above technical solution, before the test tube is inserted into the slot 5, the micro air pump 109 can be used to send gas into the air ring 101. After the gas is evenly divided by multiple partitions 105, the wind discharged from the annular exhaust port at the upper end of the air ring 101 is evenly discharged and enters the interior of the hollow rotating ring 102, and enters the air outlet 103 from the annular cavity 110 in the hollow rotating ring 102, and finally is discharged from the air outlet 103 and blown on the outer surface of the test tube. The airflow discharged from the air outlet 103 can first blow away the loose dust, fiber scraps, and particulate matter from the surface of the test tube, reducing the subsequent brush load. If there are water droplets or liquid films on the surface of the test tube, the airflow It can also blow away large droplets and take away part of the surface water film, which can reduce the amount of moisture absorbed by the bristles. The operation of the servo motor 2 106 can drive the gear 3 107 to rotate, and the rotation of the gear 3 107 drives the hollow rotating ring 2 102 to rotate. The air outlet 103 also moves with the rotation of the hollow rotating ring 2 102, which can form a spiral or annular uniform coverage to ensure that every inch of the surface of the entire test tube is treated with the same intensity of airflow, not only ensuring uniform coverage around the entire circumference, but also using the centrifugal force generated by the rotation and the vortex induced by the gas to achieve more thorough and efficient pre-cleaning, thereby providing the best workpiece surface state for the subsequent brushing process.

[0036] Instructions for use: Rotate the protective cover 3 to expose the slot 5, control the anti-scattering processing component 7 to work through the display touch part 2, and slowly insert the test tube containing the water sample to be tested into the slot 5. When the test tube moves downward in the slot 5, the anti-scattering processing component 7 inside the shell 1 can generate physical shear force on the water droplets and water marks attached to the outer surface of the glass test tube, directly removing the liquid film and trace particles from the surface of the test tube, taking away fine water marks and fine debris, and effectively removing water marks on the outer surface of the test tube, avoiding the optical transmittance from being affected by water marks and causing changes, reducing deviations and stabilizing absorbance readings, and improving detection accuracy. Then, rotate the protective cover 3 so that the protective cover 3 covers the outside of the upper end of the test tube. The protective cover 3 plays a light-shielding role, and then control the detection light source 6 and the light source receiving part 8 to work through the display touch part 2. The detection light source 6 emits light of a specific wavelength to transmit the water sample in the test tube. The light source receiving part 8 detects the intensity change of the transmitted light or scattered light and feeds the result back to the circuit board 12. The display touch part 2 can display the detection data.

Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
