Description

Technical Field

[0001] This utility model belongs to the field of instrument cleaning technology, and more specifically, relates to a pH meter cleaning device. Background Technology

[0002] A pH meter is a commonly used instrument, mainly used to precisely measure the acidity or alkalinity of liquid media. It is widely used in environmental protection, wastewater treatment, scientific research, pharmaceuticals, light industry, chemical industry and other fields. The electrode head of a pH meter is a very precise detection element. During use, it is often contaminated, which leads to increased pH measurement error, reduced sensitivity and poor stability.

[0003] Currently, although some laboratories use fully automated pH meter cleaning systems, the cleaning devices use a bottom-up spray method to wash the electrode head. The spray head is fixed at an angle upward inside the cleaning cup, which is an unreasonable spraying method. The spray liquid splashes upward, and the electrode head is easily contaminated by residual droplets in the cup, affecting the accuracy of the pH meter. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a pH meter cleaning device. This addresses the problem mentioned in the background section where, during pH meter cleaning, the spray head is fixed at an angle upward inside the cleaning cup, the angle cannot be adjusted, resulting in an unreasonable spraying method. This causes the spray liquid to splash upward, making the electrode head susceptible to contamination by residual droplets in the cup, thus affecting the accuracy of the pH meter.

[0005] To achieve the above objectives, this utility model provides a pH meter cleaning device, which includes: Frame; A lifting mechanism is provided at the top of the frame. A clamping mechanism is connected to the lifting end of the lifting mechanism, and the clamping mechanism is used to clamp at least one pH meter; A cleaning cup, which is disposed at the bottom of the frame; A ring tube is connected to the inner side of the cleaning cup. The ring tube has a water inlet hole and multiple water outlet holes on its outer periphery. Multiple telescopic rods, one end of which is connected to the inner side of the annular tube; Multiple spray heads, each of which is hinged to the other end of a telescopic rod to adjust the angle between the spray head and the axis of the cleaning cup, with the electrode head of a pH meter placed between the multiple spray heads; Multiple hoses, one end of each hose is connected to one of the water outlets, and the other end of each hose is connected to the input end of the spray head.

[0006] Preferably, the clamping mechanism includes: A disc, the middle of which is rotatably connected to the lifting end of the lifting mechanism, and the disc having multiple mounting holes on its periphery; Multiple clamps, one clamp for each of the mounting holes.

[0007] Preferably, the clamp includes: A threaded rod, wherein the edge of the disc is provided with a threaded hole, and the threaded hole is threadedly connected to the threaded rod; A rotating handle, which is connected to one end of the threaded rod; Two chucks, each semi-circular in shape, are positioned opposite each other within the mounting hole. Each chuck is connected to the other end of the threaded rod and the inner side of the mounting hole, respectively.

[0008] Preferably, the telescopic rod is an electrically operated telescopic rod.

[0009] Preferably, the other end of the telescopic rod is provided with a groove, and the two sides of the spray head are respectively damped and rotatably connected to the inside of the groove.

[0010] Preferably, the pH meter cleaning device further includes: Two extension rods, one end of each of the two extension rods being hinged to the inner sides of the annular tube; The cover has the other ends of the two extension rods respectively hinged to the two sides of the cover. The cover is positioned above multiple spray heads and has a through hole in the middle for inserting the electrode head of the pH meter.

[0011] Preferably, the cover is a transparent cover.

[0012] Preferably, the pH meter cleaning device further includes a positioning plate connected to the inner side of the frame, the positioning plate having a positioning hole, and the cleaning cup being disposed within the positioning hole.

[0013] Preferably, the spray head is tilted downwards and set at 45° to the axis of the cleaning cup.

[0014] Preferably, the bottom side of the cleaning cup is provided with a water outlet.

[0015] This invention provides a pH meter cleaning device, the advantages of which are as follows: When cleaning the electrode head of the pH meter, the angle of the spray head can be adjusted so that the spray head is tilted downwards and set at 45° with the axis of the cleaning cup. This ensures that the waste liquid is rinsed to the bottom of the cleaning cup and does not form waste liquid upwards. Then, the pH meter is clamped on the clamping mechanism, and the lifting mechanism is controlled to lower the electrode head between multiple spray heads. At this time, distilled water can be introduced into the ring tube, and the lifting mechanism is controlled to drive the electrode head to move up and down. The electrode head can be cleaned under the spray cleaning action of multiple spray heads. This pH meter cleaning device realizes the adjustment of the spray head angle. When cleaning the electrode head, the spray head can be adjusted to a reasonable tilt direction and angle to avoid the spray liquid splashing upwards.

[0016] During the cleaning process of the pH meter electrode head, when there is contamination on the electrode head that is difficult to clean, the lifting mechanism and telescopic rod can be controlled to adjust the position of the spray head, bringing the spray head closer to the electrode. This allows for more concentrated distilled water and stronger impact to rinse the electrode head, resulting in a more thorough cleaning of the electrode head, improved cleaning accuracy, and ensured the accuracy and continuity of subsequent pH meter test data.

[0017] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0021] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a pH meter cleaning device, which includes: Frame 1; Lifting mechanism 2 is located on the top of frame 1; A clamping mechanism is connected to the lifting end of the lifting mechanism 2. The clamping mechanism is used to clamp at least one pH meter 3. Cleaning cup 4 is located at the bottom of the frame 1; The ring pipe 5 is connected to the inner side of the cleaning cup 4. The ring pipe 5 is provided with a water inlet hole and multiple water outlet holes on the outer periphery of the ring pipe 5. Multiple telescopic rods 6, one end of which is connected to the inner side of the ring pipe 5; Multiple spray heads 7, each spray head 7 is hinged to the other end of a telescopic rod 6 to adjust the angle between the spray head 7 and the axis of the cleaning cup 4, and the multiple spray heads 7 are used to place the electrode head of the pH meter 3. Multiple hoses 8, one end of each hose 8 is connected to a water outlet, and the other end of each hose 8 is connected to the inlet of the spray head 7.

[0023] Specifically, to address the current problem of pH meter cleaning where the spray head is fixed upwards inside the cleaning cup at an angle that cannot be adjusted, resulting in an unreasonable spraying method, with the spray liquid splashing upwards and the electrode head easily contaminated by residual droplets in the cup, affecting the accuracy of the pH meter, this invention provides a pH meter cleaning device. The lifting mechanism 2 is an electric, pneumatic, or hydraulic lifter. When cleaning the electrode head of the pH meter 3, this pH meter cleaning device can first adjust the angle of the spray head 7 so that the spray head 7 is tilted downwards at a 45-degree angle to the axis of the cleaning cup 4. The system is configured to flush waste liquid to the bottom of the cleaning cup 4 without causing it to rise. The pH meter 3 is then clamped onto the clamping mechanism, and the lifting mechanism is controlled to lower the electrode head between multiple spray heads 7. At this time, distilled water can be introduced into the ring pipe 5, and the lifting mechanism is controlled to drive the electrode head to move up and down. The electrode head can be cleaned by the spraying action of multiple spray heads 7. This pH meter cleaning device allows for the adjustment of the angle of the spray heads 7. When cleaning the electrode head, the spray heads 7 can be adjusted to a reasonable tilt direction and angle to avoid the spray liquid splashing upwards.

[0024] During the cleaning process of the pH meter electrode head, when there is contamination on the electrode head that is difficult to remove, the lifting mechanism 2 and the telescopic rod 6 can be controlled to adjust the position of the spray head 7, bringing the spray head 7 closer to the electrode head. This allows for more concentrated distilled water and stronger impact to rinse the contaminated area, resulting in a more thorough cleaning of the electrode head. This improves cleaning accuracy and ensures the accuracy and continuity of subsequent pH meter test data. When there is no contamination on the electrode head, the spray head 7 is moved away from the electrode head to avoid excessive impact and damage to the electrode head coating.

[0025] like Figure 3 As shown, preferably, the clamping mechanism includes: The disc 9 is rotatably connected to the lifting end of the lifting mechanism 2 at its center, and the disc 9 has multiple mounting holes 10 on its periphery. Multiple clamps, one clamp for each mounting hole 10.

[0026] Specifically, multiple pH meters can be held on the disc 9, and the disc 9 can be rotated to clean each pH meter 3 in turn, which improves work efficiency.

[0027] Preferably, the fixture includes: The threaded rod 11 has a threaded hole on the edge of the disc 9, and the threaded hole is threadedly connected to the threaded rod 11. Rotary handle 12 is connected to one end of threaded rod 11; Two collets 13 are semi-circular and are positioned opposite each other in the mounting hole 10. The two collets 13 are respectively connected to the other end of the threaded rod 11 and the inner side of the mounting hole 10.

[0028] Specifically, when the pH meter 3 is inserted into the mounting hole 10, the handle 12 can be rotated. At this time, the threaded rod 11 can drive the two clamps 13 to come closer together to clamp the pH meter 3.

[0029] Preferably, the telescopic rod 6 is an electrically operated telescopic rod.

[0030] Specifically, the electric telescopic rod 6 is used to adjust the position of the spray head 7 for easy adjustment.

[0031] Preferably, the other end of the telescopic rod 6 is provided with a groove, and the two sides of the spray head 7 are respectively damped and rotatably connected to the inside of the groove.

[0032] Specifically, the groove allows for the adjustment of the angle of the spray head 7.

[0033] Preferably, the pH meter cleaning device further includes: Two extension rods 14, one end of each extension rod 14 is hinged to the inner two sides of the ring tube 5 respectively; The cover 15 has two extension rods 14, the other ends of which are hinged to the two sides of the cover 15 respectively. The cover 15 is positioned above multiple spray heads 7. The cover 15 has a through hole 16 in the middle, which is used to insert the electrode head of the pH meter 3.

[0034] Specifically, the cover 15 is used to prevent distilled water from splashing. During the cleaning process, the electrode head can be completely passed through the through hole 16 first, and then the spray head 7 can be controlled to spray. During the spraying process, the electrode head is controlled to rise through the lifting mechanism 2. The electrode head of the cleaning part will gradually rise above the cover 15. At this time, the cover 15 can block distilled water from splashing upwards, preventing waste liquid from contaminating the cleaned electrode head and further improving the cleaning effect.

[0035] Preferably, the cover 15 is a transparent cover.

[0036] Specifically, this makes it easier to observe the cleaning process.

[0037] Preferably, the pH meter cleaning device further includes a positioning plate 16, which is connected to the inner side of the frame 1. The positioning plate 16 has a positioning hole, and the cleaning cup 4 is placed in the positioning hole.

[0038] Specifically, the positioning hole is used to limit the cleaning cup 4 and prevent the cleaning cup 4 from shifting and tipping over.

[0039] Preferably, the spray head 7 is tilted downwards and set at 45° to the axis of the cleaning cup 4.

[0040] Specifically, after verification, spraying at a 45° angle not only washes the waste liquid into the cleaning cup 4, but also prevents the waste liquid from forming upwards and is less likely to splash.

[0041] Preferably, the bottom side of the cleaning cup 4 is provided with a water outlet.

[0042] Specifically, the waste liquid can be discharged in a timely manner through the outlet.

[0043] In summary, when implementing the pH meter cleaning device of this application, the pH meter cleaning device can first adjust the angle of the spray head 7 to make the spray head 7 tilt downwards and set at 45° with the axis of the cleaning cup 4, so that the waste liquid is rinsed to the bottom of the cleaning cup 4 and will not form waste liquid upwards. Then, the pH meter 3 is clamped on the clamping mechanism, and the lifting mechanism is controlled to lower the electrode head between the multiple spray heads 7. At this time, distilled water can be introduced into the ring pipe 5, and the lifting mechanism is controlled to drive the electrode head to move up and down. Under the spray cleaning action of multiple spray heads 7, the electrode head can be cleaned. The pH meter cleaning device realizes the adjustment of the angle of the spray head 7. When cleaning the electrode head, the spray head 7 can be adjusted to a reasonable tilt direction and angle to avoid the spray liquid splashing upwards.

[0044] During the cleaning process of the pH meter electrode head, when there is contamination on the electrode head that is difficult to remove, the lifting mechanism 2 and the telescopic rod 6 can be controlled to adjust the position of the spray head 7, bringing the spray head 7 closer to the electrode head. This allows for more concentrated distilled water and stronger impact to rinse the electrode head, resulting in a more thorough cleaning and improved cleaning accuracy. This ensures the accuracy and continuity of subsequent pH meter test data. When there is no contamination on the electrode head, the spray head 7 is moved away from the electrode head to avoid excessive impact and damage to the electrode head.

[0045] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
