Description

Technical Field

[0001] This utility model relates to the field of detection instrument technology, specifically to a pH detector electrode that is easy to maintain. Background Technology

[0002] A pH meter is an instrument used to measure the acidity or alkalinity of a solution. It is also called a pH meter or acid-base meter. It can measure the pH value of a solution, that is, the concentration of hydrogen ions (H+) in the solution, thereby determining the acidity or alkalinity of the solution. A pH meter is usually composed of electrodes, an amplifier, and a display.

[0003] The electrode is the core component of a pH meter. It senses the concentration of hydrogen ions in the solution by contacting it and transmits the signal to an amplifier. The amplifier then converts the signal into a digital signal, which is displayed on a monitor. Based on the displayed pH value, people can understand the acidity or alkalinity of the solution and make corresponding adjustments. The electrode should be cleaned and maintained after using the pH meter.

[0004] During testing, these impurities may participate in the detection reaction, altering the component ratios and chemical environment of the detection system, thus causing deviations in the detection data and resulting in inaccurate final results that fail to accurately reflect the actual situation of the tested object. For example, in some high-precision chemical substance content detection, impurities may react additionally with the detection reagents, causing the detected target substance content to be higher or lower than the true value.

[0005] To address the aforementioned issues, a pH meter electrode that is easy to maintain is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an easy-to-maintain pH meter electrode, solving the problem that in the prior art, impurities may participate in the detection reaction, altering the component ratios and chemical environment of the detection system, thus leading to deviations in the detection data and inaccurate final results that fail to truly reflect the actual situation of the detected object. For example, in some high-precision chemical substance content detection, impurities may react additionally with the detection reagents, causing the detected target substance content to be higher or lower than the true value.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-maintain pH meter electrode, comprising a detection body, a connecting sleeve provided on the left side of the detection body, a silicon cap fitted on the outer wall of the left side of the connecting sleeve, a connecting tube fixedly connected to the left side of the silicon cap, a tapered tube fixedly connected to the left side of the connecting tube, a threaded groove formed on the inner wall of the connecting sleeve, a connecting ring provided inside the connecting sleeve, and a fixing component fitted on the outer wall of the connecting sleeve.

[0008] By adopting the above technical solution, the air inside the silicone cap is expelled by pressing it down, and the silicone cap is released to allow the liquid to enter the interior. Liquid leakage is prevented by using a tapered tube.

[0009] As a further description of the above technical solution: the fixing component includes an upper half ring, which is disposed at the top of the connecting sleeve, and a lower half ring is disposed at the bottom of the upper half ring.

[0010] The connecting sleeve is fixed by adopting the above technical solution.

[0012] By adopting the above technical solution, the connecting ring is fixed by the threaded ring and the threaded groove.

[0013] As a further description of the above technical solution: a filter screen is fixedly connected inside the connecting ring.

[0014] By adopting the above technical solution, impurities are filtered out through a filter screen.

[0015] As a further description of the above technical solution: a connector is provided between the rear ends of the upper half circle and the lower half circle.

[0016] By adopting the above technical solution, the upper and lower halves of the circle are rotated through the connecting parts.

[0017] As a further description of the above technical solution: the connector is rotatably connected to the upper half ring via a first rotating shaft.

[0018] By adopting the above technical solution, the first rotating shaft drives the upper half of the rotation.

[0019] As a further description of the above technical solution: the lower half ring is rotatably connected to the connector via a second rotating shaft.

[0020] By adopting the above technical solution, the second rotating shaft drives the lower half of the rotation.

[0021] As a further description of the above technical solution: the front end of the upper half ring is internally threaded with a locking rod, and the locking rod is rotatably connected to the lower half ring.

[0022] By adopting the above technical solution, the upper half circle is locked and fixed by the locking rod.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] 1. The pH meter electrode provided by this utility model is easy to maintain. First, a filter screen is set inside the connecting ring, which can effectively block impurities from entering the detection body. This helps to ensure the purity of the internal environment of the detection body. At the same time, the silicone cap, connecting tube and conical tube facilitate extraction, avoiding interference from impurities to the detection process or the detection body itself, ensuring the accuracy of the detection results and the normal use and service life of the detection body.

[0025] 2. The pH meter electrode provided by this utility model is easy to maintain. It is fixed by the upper half-turn and the lower half-turn, which makes the connection between the connecting sleeve and the detection body more stable. This makes the overall installation process more convenient and the structure more stable after installation. For maintenance, simply loosen the locking rod and rotate the upper half-turn and the lower half-turn to remove the connecting sleeve. This makes the maintenance operation of the equipment simple and easy, and allows for timely inspection, replacement and other maintenance work of the components, ensuring the continuous and good operation of the entire equipment.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0032] Reference Figure 1 The present invention provides a pH meter electrode that is easy to maintain, including a detection body 1, and a connecting sleeve 2 is provided on the left side of the detection body 1.

[0033] Reference Figure 2and Figure 3 A silicon cap 3 is fitted onto the outer left side of the connecting sleeve 2. Made of silicon, the cap 3 possesses flexibility and chemical stability, protecting the connecting sleeve 2 and potentially contributing to isolation or assistance in the testing environment. A connecting tube 4 is fixedly connected to the left side of the silicon cap 3, and a tapered tube 5 is fixedly connected to the left side of the connecting tube 4. The connecting tube 4 acts as a conductive component, connecting the silicon cap 3 to the tapered tube 5 further to the left, forming a complete connection path between the components. This facilitates the transmission of substances or signals during the testing process. A threaded groove 7 is formed on the inner wall of the connecting sleeve 2. The threaded groove 7 is designed for connection with subsequent components. A reliable threaded connection is achieved to ensure the stability and disassembly of the entire structure, facilitating maintenance and component replacement. A connecting ring 6 is provided inside the connecting sleeve 2, and a threaded ring 8 is fixedly connected to the outer ring of the connecting ring 6. The threaded ring 8 is threadedly connected to the threaded groove 7. This threaded connection allows the connecting ring 6 to be easily installed inside or removed from the connecting sleeve 2. A filter screen 9 is fixedly connected inside the connecting ring 6. The filter screen 9 filters liquids or other substances flowing through the connecting sleeve 2 during the testing process, preventing impurities from entering the testing body 1 or other critical parts, thus affecting the accuracy of the test and the lifespan of the electrode.

[0034] Reference Figure 3The connecting sleeve 2 has a fixing component fitted on its outer wall. The fixing component includes an upper half-circle 10, which is located at the top of the connecting sleeve 2. A lower half-circle 11 is located at the bottom of the upper half-circle 10. A connector 12 is located between the rear ends of the upper half-circle 10 and the lower half-circle 11. The connector 12 is rotatably connected to the upper half-circle 10 via a first rotating shaft 13, and the lower half-circle 11 is rotatably connected to the connector 12 via a second rotating shaft 14. This rotatable connection allows the upper half-circle 10 to rotate flexibly relative to the connector 12, thus allowing adjustment of its angle and position to a certain extent. The lower half-circle 11 is rotatably connected to the connector 12 via the second rotating shaft 14, and similarly, the lower half-circle 11 can also rotate relative to the connector 12. In actual operation, this rotatable connection design allows the fixing component to be easily installed on or removed from the outer wall of the connecting sleeve 2. The front end of the upper half ring 10 has a threaded structure that is threadedly connected to the locking rod 15. The locking rod 15 is also threadedly connected to the front end of the upper half ring 10, and the locking rod 15 is rotatably connected to the lower half ring 11. When it is necessary to fix the connecting sleeve 2, the locking rod 15 can be rotated. Due to its threaded connection with the upper half ring 10, the locking rod 15 will move along the thread direction, thereby pulling the lower half ring 11 towards the upper half ring 10. This allows the upper half ring 10 and the lower half ring 11 to tightly hold the connecting sleeve 2, thus achieving a stable fixation of the connecting sleeve 2. When it is necessary to disassemble the fixing components or perform maintenance on the connecting sleeve 2, the locking rod 15 can be rotated in the opposite direction to loosen the fixation of the connecting sleeve 2 by the upper half ring 10 and the lower half ring 11.

[0035] Working principle: In use, connect the connecting sleeve 2 to the detection body 1. The connecting ring 6 is fixed inside the connecting sleeve 2 by the threaded groove 7 and the threaded ring 8. At the same time, the filter screen 9 inside the connecting ring 6 can prevent impurities from entering the detection body 1. Then, the silicon cap 3 is put on the outer left side of the connecting sleeve 2. The connecting tube 4 and the tapered tube 5 can be connected to other equipment. Press the silicon cap 3 to pull it out. By fixing the upper half ring 10 and the lower half ring 11, the connecting sleeve 2 and the detection body 1 are more stable. When maintenance is required, the connecting sleeve 2 can be removed for maintenance by loosening the locking rod 15 and rotating the upper half ring 10 and the lower half ring 11.
