Description

Technical Field

[0001] This utility model belongs to the field of analytical testing technology, specifically relating to a device for testing domestic water. Background Technology

[0002] Domestic water testing devices can detect basic indicators in domestic water such as pH value, hardness, and total dissolved solids. For example, by detecting the pH value, it can be determined whether the water is neutral. If the pH value deviates from the normal range, it may mean that the water has been contaminated by acids or alkalis. Detecting hardness can reveal the content of calcium, magnesium, and other ions in the water. High hardness may lead to scale formation and affect the lifespan of water-using equipment.

[0003] Some existing domestic water testing devices often struggle to separate and collect impurities in the water during use, causing impurities to mix into the water sample and interfere with the test results. Although some domestic water testing devices may have some filtration capabilities, they may still have the defect of not separating impurities thoroughly enough, which may lead to errors when observing the color of the water after the reagent is mixed. This makes it difficult to accurately assess the quality of domestic water. In addition, some existing domestic water testing devices usually use a static method to react water and reagents, resulting in a long reaction time, which may not meet the testing needs in scenarios where rapid test results are required.

[0027] Example

[0028] Reference Figures 1-5 This is an embodiment of the present invention, which provides a domestic water testing device, comprising:

[0029] The detection tank body 100 includes a carrier tank 101, a feed pipe 102 connected to the top of the carrier tank 101, a sealing cover 103 fixedly installed on the inner surface of the bottom of the carrier tank 101, a fixing ring 104 fixedly connected to the bottom of the inner wall of the feed pipe 102, a filter cartridge 105 fixedly installed on the outer end face of the fixing ring 104, an observation window 106 fixedly installed on the inner surface of the carrier tank 101, and a solenoid valve 107 connected to the bottom of the carrier tank 101.

[0030] It should be noted that the carrier tank 101 is the main container of the entire device, used to hold domestic water and pH reagent. The feed pipe 102 is used to introduce domestic water and pH reagent into the carrier tank 101. The sealing cap 103 is used to prevent liquid leakage and can also be manually opened after the test to discharge the liquid. The fixing ring 104 is not only used to support the filter cartridge 105, but also forms a circular groove at the gap between it and the inner wall of the carrier tank 101 for preliminary collection of impurities. The filter cartridge 105 is used to filter the domestic water entering the carrier tank 101, separating the water and impurities, so that the water enters the inside of the filter cartridge 105, and the impurities remain on the outside of the filter cartridge 105 and fall into the gap between the fixing ring 104 and the inner wall of the carrier tank 101 by gravity. The observation window 106 is used to observe the color of the water after it is mixed with the pH reagent and to judge the water quality by referring to the pH color chart. The solenoid valve 107 is used to discharge the impurities that fall into the gap between the fixing ring 104 and the inner wall of the carrier tank 101.

[0031] The dispensing mechanism 200 includes a drive assembly 201 for scraping and automatically collecting impurities on the surface of the filter cartridge 105, and a vibration assembly 202 for converting the power of the drive assembly 201 into a knocking motion to knock off residual impurities on the surface of the filter cartridge 105.

[0032] Specifically, the drive assembly 201 includes a servo motor 201a adapted to be installed on the top of the carrier tank 101, a connecting column 201b fixedly connected to the output end of the servo motor 201a via a coupling, a fixed plate 201c fixedly installed on the through end of the connecting column 201b, and several scrapers 201d fixedly connected to the other side of the fixed plate 201c and used in conjunction with the filter cartridge 105.

[0033] Furthermore, the drive assembly 201 also includes a hollow disc 201e fixedly mounted on the outer end face of the scraper 201d, and several pusher blocks 201f fixedly connected to the other side of the hollow disc 201e and used in conjunction with the solenoid valve 107.

[0034] Servo motor 201a is used to drive the connecting column 201b, fixed plate 201c, fixed scraper 201d, hollow plate 201e and pusher block 201f to rotate synchronously, so that the fixed scraper 201d scrapes the impurities on the surface of the filter cartridge 105 to the gap between the fixed ring 104 and the inner wall of the carrier tank 101, and then the pusher block 201f pushes the dispersed impurities into the interior of the solenoid valve 107, so that the solenoid valve 107 can be opened to discharge the impurities after the detection is completed.

[0035] Preferably, the solenoid valve 107 is used to collect and discharge impurities in the water and is located between the inner wall of the carrier tank 101 and the outer surface of the fixing ring 104. The inner wall of the scraper 201d is in sliding contact with the outer surface of the filter cartridge 105. The scrapers 201d are distributed in a circumferential array between the fixed disk 201c and the hollow disk 201e. The pusher block 201f is distributed in a circumferential array on the outer surface of the hollow disk 201e.

[0036] It should be noted that the vibration assembly 202 includes a first pulley 202a fixedly sleeved on the outer surface of the connecting column 201b, a synchronous belt 202b sleeved on the outer surface of the first pulley 202a, a second pulley 202c sleeved on the inner surface of the other end of the synchronous belt 202b, and a connecting rod 202d fixedly connected to the inner surface of the second pulley 202c.

[0037] Furthermore, the vibration assembly 202 also includes a rotating column 202e fixedly connected to the top of the connecting rod 202d, an inclined groove 202f opened on the outer surface of the rotating column 202e, and a ball bearing 202g movably connected to the inner wall of the inclined groove 202f.

[0038] Specifically, the vibration assembly 202 also includes a T-shaped rod 202h fixedly connected to the outer surface of the ball 202g, and a limiting sleeve 202i fixedly installed on the top of the bearing tank 101 and used in conjunction with the T-shaped rod 202h.

[0039] It should be noted that the first pulley 202a is used to receive the rotational power of the connecting column 201b, and through cooperation with the synchronous belt 202b, drives the second pulley 202c and the connecting rod 202d to rotate. Then, the connecting rod 202d drives the rotating column 202e and the inclined groove 202f to rotate synchronously, so that the ball 202g rotates with the rotating column 202e, driving the T-shaped rod 202h to perform vertical reciprocating motion along the inner wall of the limiting sleeve 202i, accurately striking the bearing tank 101 to generate vibration, causing the impurities attached to the surface of the filter cartridge 105 to fall off.

[0040] Furthermore, the outer end face of the connecting rod 202d is fixedly installed on the top of the bearing tank 101 by a bearing, and the outer surface of the T-shaped rod 202h is slidably connected to the inner wall of the limiting sleeve 202i.

[0041] The ball bearing 202g can follow the rotation of the inclined groove 202f to drive the T-shaped rod 202h to move vertically back and forth along the inner wall of the limiting sleeve 202i.

[0042] When in use, domestic water and pH reagent are added to the carrier tank 101 through the feed pipe 102 and filtered through the filter cartridge 105 to separate the liquid and impurities. The liquid enters the inside of the filter cartridge 105, while the impurities remain on the outside and fall into the gap between the fixing ring 104 and the inner wall of the carrier tank 101 by gravity.

[0043] Start the servo motor 201a, which drives the connecting column 201b, fixed plate 201c, scraper 201d, hollow plate 201e and pusher block 201f to rotate synchronously. The scraper 201d scrapes the impurities on the surface of the filter cartridge 105 to the gap between the fixed ring 104 and the inner wall of the carrier tank 101. Then, the pusher block 201f pushes the dispersed impurities to the solenoid valve 107 and they fall into the pipeline of the solenoid valve 107.

[0044] Meanwhile: the rotation of the connecting column 201b drives the first pulley 202a to rotate synchronously, and the cooperation between the first pulley 202a and the synchronous belt 202b drives the second pulley 202c and the connecting rod 202d to rotate, so that the connecting rod 202d drives the rotating column 202e and the inclined groove 202f to rotate synchronously. The inclined groove 202f guides the ball 202g to move, so that the ball 202g drives the T-shaped rod 202h to move vertically back and forth along the inner wall of the limiting sleeve 202i. Then, the T-shaped rod 202h accurately strikes the vibration generated by the bearing tank 101, causing the impurities that are more firmly attached to the surface of the filter cartridge 105 to fall off.

[0045] Finally, observe the color of the water after mixing with the pH reagent through the observation window 106, judge the water quality by referring to the pH color chart, manually open the sealing cap 103 to drain the liquid after the test is completed, and then open the solenoid valve 107 to drain impurities.

[0046] In summary, by combining the drive component 201 and the vibration component 202, not only can impurities in the water be separated and collected during the testing process, but also vibration can be generated by striking the carrier tank 101 without the need for an additional drive source. This causes firmly attached impurities on the surface of the filter cartridge 105 to fall off, reducing the interference of impurities on the reaction between water and pH reagent, ensuring that the tested water sample is purer. Furthermore, the series of mechanical movements generated by the drive component 201 and the vibration component 202 accelerate the reaction speed between water and pH reagent, thereby providing more reliable data for the assessment of domestic water quality and significantly improving the efficiency of water quality testing.
