Description

Technical Field

[0001] The present invention relates to the technical field of etching solution additive detection, and specifically provides a detection device and a detection method for etching solution additives. Background Technique

[0002] Etching solution additives refer to chemical substances added to the etching solution to improve the etching effect or adjust the properties of the etching solution. There are various types of etching solution additives, and each additive has its specific functions and uses.

[0003] Currently, when detecting the additive content in the etching solution, a conductivity meter and a pH meter are required to detect whether its concentration and pH value are within the specified range. During the detection, the detection personnel need to manually insert the detection probes of the conductivity meter and the pH meter into the etching solution to be measured in sequence for corresponding detections. In continuous operations of multiple detections, after one detection is completed, part of the etching solution will adhere to the outer wall of the detection probe. If not processed in time, it will affect subsequent detections. At the same time, if the detection personnel operate improperly, the etching solution may drip onto the detection table or be accidentally touched by the personnel, thus affecting the safety of the detection process. Therefore, it is necessary to process the adhered etching solution after one detection.

[0004] A patent with the publication number 202420159787.5 discloses a self-cleaning conductivity meter. In this patent, the probe is inserted into the cleaning cylinder along the second support member and is clamped and fixed with the third support member. The cleaning roller consists of a rotating rod and a soft brush. By driving the cleaning roller to rotate through the driving component, the probe inserted into the cleaning cylinder can be brushed to clean the adhered detection liquid and prevent crystallization on the probe. The position of the cleaning cylinder can be adjusted through the adjustment component to clean other probes.

[0005] However, in the actual use process of this self-cleaning conductivity meter, it still requires manual movement and fixation of multiple probes, resulting in time-consuming and laborious cleaning operations due to frequent cleaning, thus affecting continuous detection operations. Moreover, the cleaning method of this self-cleaning conductivity meter for the detection liquid still has drawbacks and cannot effectively remove the detection liquid, resulting in an impact on subsequent detection effects.

[0006] Therefore, in view of the existing structure and deficiencies, research and improvement are carried out, and a detection device and a detection method for etching solution additives are proposed. Summary of the Invention

[0007] The purpose of the present invention is to provide a detection device and a detection method for etching solution additives to solve the problems raised in the above background technique.

[0008] To achieve the above object, the present invention provides the following technical solution: A detection device for an etching solution additive, comprising a workbench and a position-changing component. In the center of the top of the workbench, an electric push rod is installed, and the top of the telescopic end of the electric push rod is connected to a driving sleeve. Inside the driving sleeve, a rotating frame is arranged, and the rotating frame consists of a round rod in the middle and a plate body fixedly connected to the top of the round rod. Inside one end of the upper part of the rotating frame, a pH meter is installed, and inside the other end of the upper part of the rotating frame, a conductivity meter is arranged.

On the outer side of the middle of the rotating frame, a guide groove is opened, and the guide groove is composed of two vertical grooves and two inclined grooves connected in an alternating manner. A guide block is fixed in the middle of the vertical groove of the guide groove. On the outer side of the driving sleeve, limit frames are symmetrically arranged, and inside the limit frames, driving columns are slidably connected. The driving columns are slidably connected to the rotating frame through the guide groove. A compression spring is sleeved on the outer side of the driving column, and the two ends of the compression spring are respectively in close contact with the middle of the driving column and the middle of the limit frame.

[0009] Further, a liquid supplementing component is arranged at one end of the workbench. The liquid supplementing component includes a water tank, a liquid supplementing pipe, and a metering cylinder. At one end of the top of the workbench, a water tank is installed. At the lower end of one side of the water tank, a liquid supplementing pipe is connected. The lower end of the liquid supplementing pipe is connected to a metering cylinder, and the metering cylinder is fixedly connected to the workbench.

[0010] Further, the liquid supplementing component further includes a first one-way valve, a sealing float ball, and a limit frame. A first one-way valve is arranged on one side of the metering cylinder. At the lower end of the liquid supplementing pipe, a sealing float ball is arranged. The top of the sealing float ball is fixedly connected to a limit frame, and the limit frame is in a right-angled shape.

[0011] Further, the liquid supplementing component further includes a first magnet and a second magnet. A first magnet is fixedly connected to the top of the limit frame. At the top of the liquid supplementing pipe, a second magnet is arranged, and the second magnet is adsorbed to the first magnet.

[0012] Further, a flushing component is arranged in the middle of the workbench. The flushing component includes a cleaning cylinder, a spring seat, a sealing plate, and a fixing ring. The cleaning cylinder is fixedly connected to the top of the workbench. A spring seat is arranged on the outer side of the cleaning cylinder, and the top of the spring seat is connected to a sealing plate. Fixing rings are arranged on the outer sides of the middle and lower parts of the pH meter and the conductivity meter.

[0013] Further, the flushing assembly further includes a driving frame, a contact button and an air pump. One side of the sealing plate is fixed with a driving frame, and the driving frame is fixedly connected to the second magnet. A contact button is arranged below the driving frame. One end of the first one-way valve is connected to an air pump, and the air pump is fixedly connected to the workbench.

[0014] Further, the flushing assembly further includes a delivery pipe, a rotating seat, a water spraying pipe and a guiding hole. The lower end of the metering cylinder is connected to a delivery pipe, and the delivery pipe is fixedly connected to the cleaning cylinder. A rotating seat is rotatably connected inside the cleaning cylinder, and the top of the rotating seat is equidistantly and circumferentially provided with a plurality of water spraying pipes in communication. A plurality of guiding holes are opened on one side of the water spraying pipe.

[0015] Further, one end of the bottom plate is provided with an anti-dripping component. The anti-dripping component includes a telescopic airbag and a fixing frame. A telescopic airbag is arranged on the top of one end of the bottom plate, and the top of the telescopic airbag is connected to a fixing frame, and the fixing frame is fixedly connected to the fixing cylinder.

[0016] Further, the anti-dripping component further includes a second one-way valve, a connecting pipe and a jet ring. Second one-way valves are arranged on both the upper and lower sides of the telescopic airbag. The end of the second one-way valve on the upper side is connected to a connecting pipe. The end of the connecting pipe is provided with a jet ring, and the jet ring is fixedly connected to the fixing frame.

[0017] Further, a detection method for an etching solution additive, which is applied to the detection device for the etching solution additive, includes the following steps:

[0018] Step 1: Place the container with the sample to be tested below the jet ring, and then control the electric push rod to drive the driving sleeve to move down. When the driving column slides to the lower end of the guiding groove, it can drive the bottom plate to squeeze the return spring, so that the pH meters and the conductivity meters on both sides move down, so that when one probe detects the sample in the container, the other probe can extend into the cleaning cylinder;

[0019] Step 2: The fixing ring outside the conductivity meter will squeeze the sealing plate, so that its top contacts and covers the top of the cleaning cylinder. During this process, the sealing plate will also drive the driving frame to move down, so that it presses the contact button, and then the air pump can be automatically started through the controller. At the same time, the second magnet will adsorb the first magnet, and then the sealing float ball can be pulled through the limiting frame to seal the lower end of the liquid supply pipe. Therefore, the air pump will deliver high-pressure air flow into the metering cylinder, and then use the air flow to squeeze the cleaning liquid in the metering cylinder into the rotating seat through the delivery pipe and spray it out from the nozzles on the water spraying pipe to flush the instrument probe. When the cleaning liquid in the metering cylinder is used up, the air flow will also be sprayed out from the water spraying pipe to dry the water droplets outside the probe;

[0020] Step 3: The electric push rod drives the drive sleeve to move upward. At this time, the reset spring will first squeeze the bottom plate, causing the rotating frame to move upward a certain distance, and moving out the probes of the pH meter and the conductivity meter. At the same time, the bottom plate will squeeze the telescopic airbag on the fixed frame, and the air inside it will enter the jet ring through the second one-way valve and the connecting pipe at the upper part and be sprayed to the outside of the probe, using the airflow to blow off the sample droplets attached to the outside of the probe;

[0021] Step 4: The spring seat will drive the sealing plate to move upward, causing the drive frame to separate from the contact button, and the air pump will stop working. At the same time, the distance between the second magnet and the first magnet is too far, and the sealed float ball will separate from the bottom of the liquid supply pipe under the action of gravity. Therefore, the cleaning liquid inside the water tank will automatically be replenished into the metering cylinder. When the metering cylinder is filled with cleaning liquid, the sealed float ball will block the bottom of the liquid supply pipe under the action of buoyancy again;

[0022] Step 5: When the drive sleeve continues to move upward, since the end of the drive column fits with the bottom of the guide block, the bottom of the guide block will guide the drive column, causing it to move to the inclined groove part of the guide groove, thereby causing the rotating frame to rotate half a circle to quickly swap the positions of the pH meter and the conductivity meter. After that, repeating the above steps can complete the detection operation of the sample solution.

[0023] The present invention provides a detection device and a detection method for an etching solution additive, having the following beneficial effects:

[0024] 1. When the electric push rod drives the drive sleeve to move downward in the present invention, the drive column will move along the vertical groove of the guide groove. And when the drive column slides to the lower end of the guide groove, it can drive the rotating frame to squeeze the reset spring, causing the pH meter and the conductivity meter on both sides to move downward, so that when one probe detects the sample in the container, the other probe can extend into the cleaning cylinder for flushing operation, thereby reducing the downtime for maintenance, being suitable for continuous detection work, and improving the detection efficiency of the etching solution;

[0025] And after detection or cleaning, with the cooperation of the electric push rod driving the drive sleeve to move upward and other components, the rotating frame will rotate half a circle to quickly swap the positions of the pH meter and the conductivity meter, so as to flush the detection probe that is not in use at the same time, which is beneficial to improving the automation degree of the equipment, and there is no need for manual replacement of the detection equipment, ensuring the safety of the detection operation.

[0026] 2. Before cleaning, the fixed ring outside the pH meter or conductivity meter will squeeze the sealing plate, causing it to drive the driving frame to move downward, pressing the contact button, and then the air pump can be automatically started through the controller. The cleaning liquid in the metering cylinder is squeezed into the rotating seat through the delivery pipe by the air flow and sprayed out from the nozzles on the water spraying pipe to wash the instrument probe. At the same time, the reaction force of the water spraying from the side guiding holes is used to drive the rotating seat to rotate, increasing the washing range and reducing the washing blind area, thereby improving the washing effect on the instrument probe, reducing the influence of the attached detection liquid on the subsequent detection, and improving the accuracy of the subsequent detection data.

[0027] Moreover, when the cleaning liquid in the metering cylinder is used up, the air flow will also be sprayed out from the water spraying pipe, so as to quickly dry the water droplets on the outside of the probe by using the high-speed air flow, avoiding the situation that the liquid droplets remain and affect the subsequent detection effect. Subsequently, when the rotating frame moves upward, the spring seat will drive the sealing plate to move upward, causing the driving frame to separate from the contact button, and the air pump will stop working. At the same time, the distance between the second magnet and the first magnet is too far, the adsorption force decreases, and the sealed floating ball will separate from the bottom of the liquid replenishing pipe under the action of gravity. Therefore, the cleaning liquid in the water tank will be automatically replenished into the metering cylinder. When the metering cylinder is filled with cleaning liquid, the sealed floating ball will block the bottom of the liquid replenishing pipe under the action of buoyancy, thus automatically limiting the water consumption each time and avoiding waste.

[0028] 3. During the detection process of the present invention, first place the sample container below the air jet ring. When the rotating frame moves downward and the instrument probe extends into the sample solution, at the same time, the bottom plate will also pull the telescopic airbag, so that the external air enters the telescopic airbag through the second one-way valve below. After the detection, when the rotating frame moves upward and the instrument probe is removed from the container, during this process, the bottom plate will squeeze the telescopic airbag on the fixed frame, and the air inside it will enter the air jet ring through the second one-way valve above and the connecting pipe and be sprayed to the outside of the probe. Therefore, during the upward movement of the probe, the air flow can be used to blow off the sample liquid droplets attached to the outside of the probe, avoiding the situation of dripping due to more adhered liquid during the transfer process.

Detailed implementation manners

[0037] Embodiment 1

[0038] Please refer to Figures 1 to 3, the present invention provides a technical solution: a detection device for an etching solution additive, including a workbench 1 and a position-changing assembly 7. A power push rod 2 is arranged at the center of the top of the workbench 1, and the top of the telescopic end of the power push rod 2 is connected with a driving sleeve 3. A rotating frame 4 is arranged inside the driving sleeve 3, and the rotating frame 4 is composed of a round rod in the middle and a plate body fixedly connected to the top of the round rod. A pH meter 5 is arranged inside one end of the upper part of the rotating frame 4, and a conductivity meter 6 is arranged inside the other end of the upper part of the rotating frame 4. The position-changing assembly 7 is arranged on the outer side of the lower part of the rotating frame 4. The position-changing assembly 7 includes a bottom plate 701, a return spring 702, a fixed cylinder 703, a guide groove 704, a guide block 705, a limit frame 706, a driving column 707 and a compression spring 708. The bottom of the rotating frame 4 is rotatably connected with the bottom plate 701, and the bottom of the bottom plate 701 is connected with the return spring 702. The outer side of the bottom plate 701 is slidably connected with the fixed cylinder 703. A guide groove 704 is opened on the outer side of the middle part of the rotating frame 4, and the guide groove 704 is composed of two vertical grooves and two inclined grooves connected in an alternating manner. A guide block 705 is fixed in the middle of the vertical groove of the guide groove 704. Limit frames 706 are symmetrically arranged on the outer side of the driving sleeve 3, and a driving column 707 is slidably connected inside the limit frame 706. The driving column 707 is slidably connected with the rotating frame 4 through the guide groove 704. A compression spring 708 is sleeved on the outer side of the driving column 707, and the two ends of the compression spring 708 are respectively in close contact with the middle part of the driving column 707 and the middle part of the limit frame 706;

[0039] The specific operation is as follows. When the power push rod 2 is in the extended state, the probe position of the pH meter 5 is relatively high and will not block the placement operation of the sample container. Then, place the sample container to be tested below the air jet ring 1005. After that, when the power push rod 2 drives the driving sleeve 3 to move downward, the driving column 707 will move along the vertical groove of the guide groove 704. During this process, since the driving column 707 has a sliding space inside the driving sleeve 3, when the driving column 707 slides downward and contacts the guide block 705, it can slide outward under the guidance of its inclined surface and squeeze the compression spring 708, so as to automatically avoid the guide block 705. And when the driving column 707 slides to the lower end of the guide groove 704, it can drive the bottom plate 701 to squeeze the return spring 702, so that the pH meters 5 and the conductivity meters 6 on both sides move downward, so that when one probe detects the sample in the container, the other probe can extend into the cleaning cylinder 901 for flushing operation, thereby reducing the downtime for maintenance;

[0040] And after detection or cleaning, as the electric push rod 2 drives the driving sleeve 3 to move upward, at this time, the reset spring 702 will first squeeze the bottom plate 701, causing the rotating frame 4 to move upward a certain distance, and removing the probes of the pH meter 5 and the conductivity meter 6 from the sample container and the cleaning cylinder 901 respectively. During this process, the driving column 707 will move to the bottom of the guiding block 705. Subsequently, as the driving sleeve 3 continues to move upward, at this time, the compression spring 708 will push the driving column 707 under the limitation of the limiting frame 706, so that the end of the driving column 707 fits against the bottom of the guiding block 705. At the same time, because the bottom of the guiding block 705 blocks too much of the top of the driving column 707, the driving column 707 cannot cross the guiding block 705 and continue to move upward along the vertical groove. Instead, under the guidance of the bottom inclination angle of the guiding block 705, it will move to the inclined groove part of the guiding groove 704, thus causing the rotating frame 4 to rotate half a circle, quickly swapping the positions of the pH meter 5 and the conductivity meter 6. And after the swapping, because the driving column 707 will move into the vertical groove of the guiding groove 704 again, its angle can be automatically locked. Therefore, during the lifting and lowering of the driving sleeve 3, the positions of the pH meter 5 and the conductivity meter 6 can be automatically swapped to facilitate flushing the detection probes that are not in use at the same time, which is beneficial to improving the automation degree of the equipment.

[0041] Embodiment 2

[0042] Please refer to Figures 4 to 6 , a liquid replenishing assembly 8 is arranged at one end of the workbench 1. The liquid replenishing assembly 8 includes a water tank 801, a liquid replenishing pipe 802 and a metering cylinder 803. The water tank 801 is arranged at the top end of one side of the workbench 1. A liquid replenishing pipe 802 is connected to the lower end of one side of the water tank 801. The lower end of the liquid replenishing pipe 802 is connected to the metering cylinder 803, and the metering cylinder 803 is fixedly connected to the workbench 1. The liquid replenishing assembly 8 further includes a first one-way valve 804, a sealing float 805 and a limiting frame 806. The first one-way valve 804 is arranged on one side of the metering cylinder 803. The sealing float 805 is arranged at the lower end of the liquid replenishing pipe 802, and a limiting frame 806 is fixed to the top of the sealing float 805, and the limiting frame 806 is in a right-angled shape. The liquid replenishing assembly 8 further includes a first magnet 807 and a second magnet 808. The first magnet 807 is fixed to the top of the limiting frame 806. The second magnet 808 is arranged at the top of the liquid replenishing pipe 802, and the second magnet 808 and the first magnet 807 are mutually adsorbed;

[0043] In the middle of the workbench 1, a flushing assembly 9 is arranged. The flushing assembly 9 includes a cleaning cylinder 901, a spring seat 902, a sealing plate 903 and a fixing ring 904. The cleaning cylinder 901 is fixed on the top of the workbench 1, and the spring seat 902 is arranged on the outer side of the cleaning cylinder 901. The top of the spring seat 902 is connected with the sealing plate 903. Fixing rings 904 are arranged on the outer sides of the middle and lower parts of the pH meter 5 and the conductivity meter 6. The flushing assembly 9 further includes a driving frame 905, a contact button 906 and an air pump 907. One side of the sealing plate 903 is fixed with the driving frame 905, and the driving frame 905 is fixedly connected with the second magnet 808. A contact button 906 is arranged below the driving frame 905. One end of the first one-way valve 804 is connected with the air pump 907, and the air pump 907 is fixedly connected with the workbench 1. The flushing assembly 9 further includes a delivery pipe 908, a rotating seat 909, a water spraying pipe 910 and a guiding hole 911. The lower end of the metering cylinder 803 is connected with the delivery pipe 908, and the delivery pipe 908 is fixedly connected with the cleaning cylinder 901. The rotating seat 909 is rotatably connected inside the cleaning cylinder 901, and water spraying pipes 910 are equidistantly communicated in a circumferential distribution on the top of the rotating seat 909. A plurality of guiding holes 911 are opened on one side of the water spraying pipe 910. Specifically, the rotating seat 909 is a circular ring structure, and an annular groove is opened on the outer ring surface of the circular ring. A sealing ring is arranged at the part where the circular ring structure of the rotating seat 909 is rotatably connected with the cleaning cylinder 901 to prevent the cleaning liquid from overflowing. The delivery pipe 908 passes through the cleaning cylinder 901 and is communicated with the annular groove of the rotating seat 909. That is to say, the cleaning liquid can be sent into the annular groove of the rotating seat 909 from the delivery pipe 908 and then sent into the water spraying pipe 910 to be sprayed out.

[0044] The specific operation is as follows. When the fixing ring 904 outside the pH meter 5 or the conductivity meter 6 presses down the sealing plate 903, the top of the sealing plate 903 will also contact and block the top of the cleaning cylinder 901, thus preventing the cleaning liquid from splashing out. During this process, the sealing plate 903 will also drive the driving frame 905 to move downwards, so that it moves towards the contact button 906 and presses it, and the air pump 907 can be automatically started through the controller.

[0045] Meanwhile, the second magnet 808 will also attract the first magnet 807, and then the sealing float ball 805 can be pulled by the limiting frame 806 to seal the lower end of the liquid replenishing pipe 802. Therefore, the air pump 907 will transport high-pressure air flow into the metering cylinder 803, and then the cleaning liquid in the metering cylinder 803 will be extruded through the delivery pipe 908 into the middle of the cleaning cylinder 901 by the air flow, promoting the cleaning liquid to flow inside the rotating seat 909. Since the water spraying pipe 910 is composed of a pipe and a nozzle, the cleaning liquid can be sprayed out from the nozzles on the water spraying pipe 910 to wash the instrument probe. At the same time, the nozzles have a certain inclination angle, and the orientation of the guiding holes 911 is parallel to the tangential direction of the annular rotating seat 909. Therefore, the reaction force when spraying water from the guiding holes 911 will always push the rotating seat 909 in the tangential direction of the rotating seat 909, causing it to rotate, so as to improve the flushing range and reduce the flushing blind area;

[0046] When the cleaning liquid in the metering cylinder 803 is used up, the air flow will be sprayed out from the water spraying pipe 910, and then the water droplets outside the probe will be quickly dried by the high-speed air flow, avoiding the situation that liquid droplets remain and affect the subsequent detection effect. Subsequently, when the rotating frame 4 moves upward, since the spring seat 902 is composed of a spring and a damping rod, the elastic force of the spring can be used to drive the sealing plate 903 to move upward, so that the driving frame 905 is separated from the contact button 906, and the air pump 907 will stop working. At the same time, the distance between the second magnet 808 and the first magnet 807 is too far, the adsorption force is reduced, and the sealing float ball 805 will separate from the bottom of the liquid replenishing pipe 802 under the action of gravity. Therefore, the cleaning liquid inside the water tank 801 will automatically replenish into the metering cylinder 803. At this time, the first one-way valve 804 will block the liquid from entering the air pump 907. When the metering cylinder 803 is filled with cleaning liquid, the sealing float ball 805 will block the bottom of the liquid replenishing pipe 802 under the action of buoyancy, thus automatically limiting the water consumption each time and avoiding excessive waste.

[0047] Please refer to Figure 1 and Figure 7 As shown in FIGS. and, one end of the bottom plate 701 is provided with a drip-proof component 10. The drip-proof component 10 includes a telescopic airbag 1001 and a fixing frame 1002. The telescopic airbag 1001 is arranged at the top of one end of the bottom plate 701, and the top of the telescopic airbag 1001 is connected with the fixing frame 1002, and the fixing frame 1002 is fixedly connected with the fixing cylinder 703. The drip-proof component 10 further includes a second one-way valve 1003, a connecting pipe 1004 and a jet ring 1005. The second one-way valves 1003 are arranged on both the upper and lower sides of the telescopic airbag 1001. The end of the second one-way valve 1003 located on the upper side is connected with the connecting pipe 1004. The end of the connecting pipe 1004 is provided with the jet ring 1005, and the jet ring 1005 is fixedly connected with the fixing frame 1002;

[0048] The specific operation is as follows. During the detection, when the rotating frame 4 moves downward and the instrument probe extends into the sample solution, at the same time, the rotating frame 4 also drives the bottom plate 701 to move downward. Since the position of the telescopic airbag 1001 is fixed, the distance between the bottom plate 701 and the telescopic airbag 1001 becomes larger, which will pull the telescopic airbag 1001, causing the external air to enter the telescopic airbag 1001 through the second one-way valve 1003 below. After the detection is completed, when the rotating frame 4 moves upward and the instrument probe is removed from the container, during this process, the bottom plate 701 will squeeze the telescopic airbag 1001 on the fixing frame 1002, so that the air inside it enters the jet ring 1005 through the second one-way valve 1003 above and the connecting pipe 1004 and is sprayed outside the probe. Since the nozzle outlet on the jet ring 1005 is small and the air storage capacity of the telescopic airbag 1001 is large, when the large-capacity air flow passes through the small-diameter channel, its flow rate will increase, and a high-speed air flow can be formed. The sprayed air flow will form a blocking force, similar to an "air flow scraper". Therefore, during the upward movement of the probe, a larger air flow is used to intercept and blow off the liquid outside the probe, avoiding the situation that the liquid adheres to the outside of the probe and drips during the subsequent transfer operation, resulting in contamination of the workbench 1 surface.

[0049] Embodiment 3

[0050] Based on the above-mentioned Embodiments 1 and 2, a detection method for an etching solution additive is proposed, which is applied to a detection device for an etching solution additive, and includes the following steps:

[0051] Step 1: Place the container with the sample to be measured below the jet ring 1005, and then control the electric push rod 2 to drive the drive sleeve 3 to move downward. When the drive column 707 slides to the lower end of the guide groove 704, it can drive the bottom plate 701 to squeeze the return spring 702, so that the pH meters 5 and the conductivity meters 6 on both sides move downward, so that when one probe detects the sample in the container, the other probe can extend into the cleaning cylinder 901.

[0052] Step 2: The fixed ring 904 outside the conductivity meter 6 presses against the sealing plate 903, causing its top to contact and cover the top of the cleaning cylinder 901. During this process, the sealing plate 903 also drives the driving frame 905 downward, pressing against the contact button 906, enabling the air pump 907 to be automatically started through the controller. At the same time, the second magnet 808 also attracts the first magnet 807, enabling the sealing float ball 805 to be pulled by the limiting frame 806 to seal the lower end of the liquid replenishing pipe 802. Therefore, the air pump 907 delivers high-pressure air flow into the metering cylinder 803, and the cleaning liquid in the metering cylinder 803 is squeezed into the rotating seat 909 through the delivery pipe 908 and sprayed out from the nozzles on the water spraying pipe 910 to wash the instrument probe. Moreover, when the cleaning liquid in the metering cylinder 803 is used up, the air flow will also be sprayed out from the water spraying pipe 910 to blow dry the water droplets on the outer side of the probe;

[0053] Step 3: The electric push rod 2 drives the driving sleeve 3 upward. At this time, the reset spring 702 first presses against the bottom plate 701, causing the rotating frame 4 to move upward a certain distance first, moving the probes of the pH meter 5 and the conductivity meter 6 out. At the same time, the bottom plate 701 presses against the telescopic airbag 1001 on the fixing frame 1002, and the air inside it enters the air jet ring 1005 through the upper second one-way valve 1003 and the connecting pipe 1004 and is sprayed onto the outer side of the probe, using the air flow to blow off the sample liquid droplets attached to the outer side of the probe;

[0054] Step 4: The spring seat 902 drives the sealing plate 903 upward, causing the driving frame 905 to separate from the contact button 906, and the air pump 907 stops working. At the same time, the distance between the second magnet 808 and the first magnet 807 is too far, and the sealing float ball 805 separates from the bottom of the liquid replenishing pipe 802 under the action of gravity. Therefore, the cleaning liquid inside the water tank 801 automatically replenishes into the metering cylinder 803. When the metering cylinder 803 is filled with cleaning liquid, the sealing float ball 805 blocks the bottom of the liquid replenishing pipe 802 again under the action of buoyancy;

[0055] Step 5: When the driving sleeve 3 continues to move upward, since the end of the driving column 707 fits against the bottom of the guiding block 705, the bottom of the guiding block 705 guides the driving column 707, causing it to move to the inclined groove part of the guiding groove 704, thereby causing the rotating frame 4 to rotate half a circle to quickly swap the positions of the pH meter 5 and the conductivity meter 6. After that, repeating the above steps can complete the detection operation of the sample solution;

[0056] During use, first place the container of the sample to be measured below the air jet ring 1005. Secondly, when the electric push rod 2 drives the drive sleeve 3 to move downward, the drive column 707 will move along the vertical groove of the guide groove 704. During this process, since the drive column 707 can slide inside the outer side of the drive sleeve 3, it can automatically avoid the guide block 705. And when the drive column 707 slides to the lower end of the guide groove 704, it can drive the bottom plate 701 to squeeze the return spring 702, so that the pH meters 5 and conductivity meters 6 on both sides move downward, enabling one of the probes to detect the sample in the container while the other probe can extend into the cleaning cylinder 901. At the same time, the bottom plate 701 will also pull the telescopic airbag 1001, causing the external air to enter the telescopic airbag 1001 through the second one-way valve 1003 below. Then, the fixed ring 904 outside the conductivity meter 6 will squeeze the sealing plate 903, making its top contact and block the top of the cleaning cylinder 901. During this process, the sealing plate 903 will also drive the drive frame 905 to move downward, pressing the contact button 906, and the air pump 907 can be automatically started through the controller. At the same time, the second magnet 808 will adsorb the first magnet 807, and the sealing float ball 805 can be pulled by the limit frame 806 to seal the lower end of the liquid supply pipe 802. Therefore, the air pump 907 will deliver high-pressure air flow into the metering cylinder 803, and then use the air flow to squeeze the cleaning liquid in the metering cylinder 803 into the rotating seat 909 through the delivery pipe 908 and spray it out from the nozzles on the water spray pipe 910 to wash the instrument probe, and cooperate with the reaction force of the water sprayed from the side guide holes 911 to drive the rotating seat 909 to rotate. And when the cleaning liquid in the metering cylinder 803 is used up, the air flow will spray out from the water spray pipe 910, so as to quickly dry the water droplets on the outer side of the probe by using the high-speed air flow. And the waste liquid and air flow can be discharged through the collection pipe at the bottom of the cleaning cylinder 901. Then, after the detection and cleaning are completed, as the electric push rod 2 drives the drive sleeve 3 to move upward, at this time the return spring 702 will first squeeze the bottom plate 701, making the rotating frame 4 move upward a certain distance to move the probes of the pH meter 5 and the conductivity meter 6 out. At the same time, the bottom plate 701 will squeeze the telescopic airbag 1001 on the fixed frame 1002, and the air inside it will enter the air jet ring 1005 through the second one-way valve 1003 and the connecting pipe 1004 above and spray it to the outside of the probe, using the air flow to blow off the sample liquid droplets attached to the outside of the probe. After that, when the rotating frame 4 moves upward, the spring seat 902 will drive the sealing plate 903 to move upward, separating the drive frame 905 from the contact button 906, and the air pump 907 will stop working. At the same time, the distance between the second magnet 808 and the first magnet 807 is too far and the adsorption force decreases, and the sealing float ball 805 will separate from the bottom of the liquid supply pipe 802 under the action of gravity. Therefore, the cleaning liquid inside the water tank 801 will automatically replenish into the metering cylinder 803. At this time, the first one-way valve 804 will block the liquid from entering the air pump 907. And when the metering cylinder 803 is filled with cleaning liquid,The sealed floating ball 805 will block the bottom of the liquid replenishing pipe 802 under the action of buoyancy. Finally, as the driving sleeve 3 continues to move upward, the driving column 707 will slide inside the guiding groove 704. At this time, the compression spring 708 will push the driving column 707 under the limitation of the limiting frame 706, so that the end of the driving column 707 fits with the bottom of the guiding block 705. Therefore, the bottom of the guiding block 705 will guide the driving column 707 to move to the inclined groove part of the guiding groove 704, thereby causing the rotating frame 4 to rotate half a circle to quickly swap the positions of the pH meter 5 and the conductivity meter 6. And after the swapping, since the driving column 707 will move into the vertical groove of the guiding groove 704 again, its angle can be automatically locked. After that, by repeating the above detection operation, the detection probe that is not in use during the detection can be rinsed, which is beneficial to improving the automation degree of the equipment.
