Description

Technical Field

[0001] This utility model belongs to the field of water detection technology, specifically, it relates to a liquid titrator for water detection. Background Technology

[0002] Drinking water quality is primarily assessed based on its impact on human health. In addition to physical and chemical indicators, its water quality standards also include microbiological indicators. For industrial water, the focus is on whether it affects product quality or is likely to damage containers and pipes. Therefore, water testing is necessary, and current water testing typically uses a titrator for separation.

[0003] A search revealed that CN219038946U discloses a liquid titrator for water detection. By setting up a container and a dispensing component, it is possible to easily control the amount of water to be tested, making it convenient to operate and avoiding the situation of adding too much water. This solves the problem that existing liquid titrators are not convenient to control the amount of water added, are prone to adding too much water, which will cause sample waste, and that excessive sample volume will affect the test results.

[0004] This titrator can control the amount of water added for testing. However, after the water is added to the container, there is no mechanism to stir and mix it. As a result, the water will settle for a long time and sedimentation will occur, which will affect the quality of the liquid being dispensed and thus the accuracy of the subsequent water test data.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To address the technical problem that while the titrator can control the amount of water added for testing, the lack of a stirring and mixing mechanism after the water is added to the receiving chamber leads to sedimentation due to prolonged static state, which affects the quality of the dispensed liquid and consequently the accuracy of subsequent water testing data, the basic concept of this invention is as follows:

[0007] A separatory titrator for water detection, comprising a main housing;

[0008] A water inlet is connected to the top of the main tank. An agitator is installed inside the main tank, and a drip dispensing mechanism is installed at the bottom of the agitator. The agitator includes a fixing plate fixedly connected to the outer wall of the main tank.

[0009] A motor is fixedly connected to the inner outer wall of the fixed plate. A rotating rod is fixedly connected to the output end of the motor. A support rod is fixedly connected to the end of the rotating rod away from the motor. A groove is formed on the outer wall of the support rod. A sliding rod is fixedly connected to the inner wall of the groove. A slider is slidably connected to the outer wall of the sliding rod. A first spring is fixedly connected to the outer wall of the slider. The end of the first spring away from the slider is fixedly connected to the inner wall of the groove. A fixing block is fixedly connected to the top of the slider. A support ring is fixedly connected to the end of the fixing block away from the slider. A stirring blade is fixedly connected to the outer wall of the support ring. A transmission wheel is fixedly connected to the outer wall of the rotating rod. A transmission belt is rotatably connected to the outer wall of the transmission wheel. A rotating column is rotatably connected to the other end of the transmission belt. A cam groove is formed on the outer wall of the rotating column. A connecting push rod is slidably connected to the outer wall of the cam groove.

[0010] In a preferred embodiment of this utility model, the dripping mechanism includes a second spring fixedly connected to the bottom end of the inner wall of the upper inner cavity of the main body. A connecting ring is fixedly connected to the end of the second spring away from the inner wall of the upper inner cavity. A leaking cylinder is fixedly connected to the inner wall of the connecting ring. A connecting rod is fixedly connected to the top end of the leaking cylinder. The outer wall of the connecting rod slides through the top end of the main body. A connecting plate is fixedly connected to the end of the connecting rod away from the leaking cylinder. A drip tube is connected to the bottom end of the main body, and a valve is provided in the drip tube.

[0011] In a preferred embodiment of the present invention, a limiting groove is provided at the bottom end of the inner wall of the top cavity of the main housing, and the bottom outer wall of the connecting push rod is slidably connected to the inner wall of the limiting groove and fits snugly against the inner wall of the limiting groove.

[0012] In a preferred embodiment of this utility model, the number of stirring blades is two, and the stirring blades are distributed in a symmetrical structure at the upper and lower ends of the support rod.

[0013] In a preferred embodiment of this utility model, the inner wall of the groove at the top of the support rod is fitted to the outer wall of the slider.

[0014] In a preferred embodiment of this utility model, a liquid outlet is provided at the bottom end of the inner wall of the upper inner cavity of the main box, and the inner wall of the liquid outlet fits snugly against the outer wall of the leakage cylinder.

[0015] In a preferred embodiment of this utility model, the outer wall of the leakage cylinder is provided with through holes, and the number of through holes is two, which are distributed on the left and right sides of the outer wall in a left-right symmetrical structure.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] This invention involves starting a motor, whose output will drive a rotating rod to rotate. This rotation of the rod causes the support rod and stirring blades to rotate, thus mixing the water to be tested and preventing the sedimentation of impurities and other substances. Simultaneously, the rotation of the rod drives the transmission wheel and transmission belt, which in turn drives the rotating column. This rotating column then drives the cam groove to rotate, causing the connecting push rod to move back and forth. When the connecting push rod moves to the left, it contacts and compresses the support ring. The compressed support ring then moves the fixed block and the slider. The slider moves along the outer wall of the sliding rod, simultaneously compressing the first spring. As the cam groove continues to rotate, causing the connecting push rod to move to the right, the connecting push rod loses its compressive force on the support ring. The first spring then rebounds, causing the support ring and stirring blades to return to their original position to the right. This repeated movement of the stirring blades increases the mixing range of the water to be tested, improving the mixing effect and ultimately enhancing the accuracy of subsequent testing data.

[0018] In this invention, when dispensing, the connecting plate can be pressed down, which will cause the connecting rod to move downward, thereby moving the leaking cylinder downward. During the downward movement of the leaking cylinder, the second spring will be compressed until the through hole on the outer wall of the leaking cylinder moves to the bottom cavity. At this point, the water to be tested will flow downward through the through hole into the dropper. Then, the valve can be opened to discharge the water to be tested through the dropper. This method can control the downward extension of the through hole on the outer wall of the leaking cylinder according to the pressure applied by the operator, thereby controlling the water output, making it quite convenient to use.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figures 1 to 4 As shown, a water titrator for water testing includes a main housing 1, connected to a water inlet 2 located at the top of the main housing 1. A stirring mechanism 31 is installed inside the main housing 1, and a dispensing mechanism 32 is installed at the bottom of the stirring mechanism 31. The stirring mechanism 31 includes a fixing plate 311 fixedly connected to the outer wall of the main housing 1. A motor 312 is fixedly connected to the inner outer wall of the fixing plate 311. A rotating rod 313 is fixedly connected to the output end of the motor 312. A support rod 314 is fixedly connected to the end of the rotating rod 313 away from the motor 312. A groove is formed on the outer wall of the support rod 314, and a sliding rod 315 is fixedly connected to the inner wall of the groove. A slider 316 is slidably connected to the outer wall of the sliding rod 315. A first spring 317 is fixedly connected to the outer wall of block 316. The end of the first spring 317 away from slider 316 is fixedly connected to the inner wall of the groove. A fixing block 318 is fixedly connected to the top of slider 316. A support ring 319 is fixedly connected to the end of fixing block 318 away from slider 316. A stirring blade 3110 is fixedly connected to the outer wall of support ring 319. A transmission wheel 3111 is fixedly connected to the outer wall of rotating rod 313. A transmission belt 3112 is rotatably connected to the outer wall of transmission wheel 3111. A rotating column 3113 is rotatably connected to the other end of transmission belt 3112. A cam groove 3114 is opened on the outer wall of rotating column 3113. A connecting push rod 3115 is slidably connected to the outer wall of cam groove 3114.

[0028] Furthermore, a limiting groove is provided at the bottom of the inner wall of the top cavity of the main housing 1. The bottom outer wall of the connecting push rod 3115 is slidably connected to the inner wall of the limiting groove and fits snugly against the inner wall of the limiting groove. This can limit the connecting push rod 3115. At the same time, the snug fit with the limiting groove can ensure the stability of the connecting push rod 3115 during reciprocating movement.

[0029] Furthermore, there are two stirring blades 3110, which are distributed symmetrically at the upper and lower ends of the support rod 314, so that the water to be tested inside the main tank 1 can be stirred and flowed at the upper and lower positions.

[0030] Furthermore, the inner wall of the groove at the top of the support rod 314 fits snugly against the outer wall of the slider 316, thus ensuring a tight fit between the slider 316 and the inner wall of the groove, thereby ensuring the stability of the slider 316 during movement.

[0031] The dripping mechanism 32 includes a second spring 321 fixedly connected to the bottom of the inner wall of the upper inner cavity of the main housing 1. A connecting ring 322 is fixedly connected to the end of the second spring 321 away from the inner wall of the upper inner cavity. A leaking cylinder 323 is fixedly connected to the inner wall of the connecting ring 322. A connecting rod 324 is fixedly connected to the top of the leaking cylinder 323. The outer wall of the connecting rod 324 slides through the top of the main housing 1. A connecting plate 325 is fixedly connected to the end of the connecting rod 324 away from the leaking cylinder 323. A drip tube 326 is connected to the bottom of the main housing 1. A valve 327 is provided in the drip tube 326.

[0032] Furthermore, a liquid outlet is provided at the bottom of the inner wall of the upper part of the main housing 1. The inner wall of the liquid outlet fits snugly against the outer wall of the liquid leakage cylinder 323, so that the liquid leakage cylinder 323 can fit tightly against the liquid outlet, ensuring that the liquid leakage cylinder 323 can seal the liquid outlet in the initial state.

[0033] Furthermore, the outer wall of the liquid discharge cylinder 323 is provided with two through holes, which are distributed symmetrically on the left and right sides of the outer wall. The liquid can be discharged through the through holes as the liquid discharge cylinder 323 moves downward, thus completing the subsequent dripping operation.

[0034] The implementation principle of a water titrator for water testing in this embodiment is as follows: First, open the water inlet 2 and put the water to be tested into the main tank 1. Then, start the motor 312, whose output end will drive the rotating rod 313 to rotate. The rotation of the rotating rod 313 drives the support rod 314 and the stirring blade 3110 to rotate, thereby stirring and mixing the water to be tested to prevent impurities and other substances in the water from settling. Simultaneously, the rotation of the rotating rod 313 drives the transmission wheel 3111 and the transmission belt 3112 to rotate, which in turn drives the rotating column 3113 to rotate. The rotating column 3113 drives the cam groove 3114 to rotate. The rotation of the cam groove 3114 drives the connecting push rod 3115 to move back and forth. When the connecting push rod 3115 moves to the left... When in motion, it can contact and squeeze the support ring 319. The squeezed support ring 319 will drive the fixed block 318 and the slider 316 to move. At this time, the slider 316 will move on the outer wall of the slide rod 315, and at the same time drive the first spring 317 to compress. As the cam groove 3114 continues to rotate, it drives the connecting push rod 3115 to move to the right. The connecting push rod 3115 will lose its squeezing effect on the support ring 319. At this time, the first spring 317 can rebound and reset, driving the support ring 319 and the stirring blade 3110 to reset to the right. By repeating this process, the stirring blade 3110 can move back and forth, thereby increasing the stirring range of the stirring blade 3110 on the water to be tested, improving the stirring effect, and further improving the accuracy of subsequent test data.

[0035] When performing the dripping, the connecting plate 325 can be pressed down. At this time, the connecting plate 325 will drive the connecting rod 324 to move downward, which will drive the dripping cylinder 323 to move downward. During the downward movement of the dripping cylinder 323, it will squeeze the second spring 321 until the through hole on the outer wall of the dripping cylinder 323 moves to the bottom cavity. At this time, the water to be tested will flow downward through the through hole into the dripping tube 326. Then, the valve 327 can be opened to discharge the water to be tested through the dripping tube 326. This method can control the downward extension of the through hole on the outer wall of the dripping cylinder 323 according to the pressure of the operator, thereby controlling the water output, which is more convenient to use.
