Description

Technical Field

[0001] This utility model belongs to the field of water quality testing technology, specifically relating to a portable multifunctional water quality testing pen. Background Technology

[0002] The core value of water quality testing lies first and foremost in safeguarding life and health. The safety of every drop of water is directly related to human survival. When E. coli or Vibrio cholerae lurks in water, it becomes a vector for infectious diseases.

[0003] Traditional water quality testing relies on large laboratory equipment, which is cumbersome, time-consuming, and costly, making it difficult to meet the immediate testing needs of daily life. Especially in scenarios such as fieldwork, household water use, and emergency disaster relief, portable, fast, and easy-to-use water quality testing tools have become essential. Water quality testing pens have emerged to address this need, simplifying the complex testing process into a one-click operation. This allows even non-professionals to obtain key water quality parameters such as pH value, total dissolved solids (TDS), and residual chlorine content within seconds. Their widespread adoption has brought water quality monitoring from professional laboratories to households, making it an everyday tool for ensuring drinking water safety.

[0004] The evolution of water quality testing pens is inseparable from technological breakthroughs in multiple fields. The maturity of microelectronics technology has enabled the miniaturization of high-precision sensors; for example, the size of pH glass electrodes has been reduced from bulky laboratory probes to the size of a pen tip. Advances in signal processing chips (such as low-noise operational amplifiers) ensure the accurate acquisition of weak electrical signals. Developments in materials science have led to more durable probes; for example, the invention of solid-state reference electrodes reduces the risk of leakage from traditional electrolytes and extends their lifespan. Furthermore, the integration of the Internet of Things (IoT) and wireless transmission technologies allows modern water quality testing pens to not only display data locally but also synchronize results to mobile phones or the cloud via Bluetooth or Wi-Fi, enabling long-term monitoring and data analysis.

[0005] Despite significant advancements in the convenience of water quality testing pens, several limitations remain. Their single-function nature restricts their application scenarios; most pens can only measure one parameter, while water quality safety often requires comprehensive evaluation of multiple indicators. Therefore, providing a water quality testing pen capable of simultaneously measuring multiple water quality parameters is a crucial technical problem that this invention aims to solve. Utility Model Content

[0006] In view of this, the present invention provides a portable multifunctional water quality testing pen.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A portable multifunctional water quality testing pen includes a pen barrel, a probe quick-change telescopic mechanism, a split multi-electrode module, and a probe magnetic sleep chamber. The split multi-electrode module includes an OPR probe and a pH probe. The probe magnetic sleep chamber is located at the top of the water quality testing pen, and the probe quick-change telescopic mechanism is located at the bottom of the water quality testing pen.

[0009] Furthermore, the probe quick-change telescopic mechanism includes a groove embedded in the side of the pen barrel, a connecting rod, and an axial adjustment ring;

[0010] The groove has two first planes, which are parallel to each other and perpendicular to the direction of the pen barrel. A first through hole is formed on both first planes at the same height. A second through hole is formed on the bottom end face of the pen barrel.

[0011] The side of the connecting rod is covered with continuous threads. The connecting rod passes through the second through hole and the two first through holes in sequence to be rotatably installed at the bottom of the pen barrel. At the same time, the end of the connecting rod is exposed at the outer bottom of the pen barrel.

[0012] The axial adjusting ring is a hollow cylindrical structure with internal threads, and the axial adjusting ring is threaded onto the connecting rod at the groove position.

[0013] Furthermore, the connecting rod includes a first rod body and a second rod body connected in sequence. The second rod body has a hollow structure. The first rod body is provided with a first magnetic connector, which is used to connect one of the split electrode modules.

[0014] Furthermore, the probe magnetic sleep chamber includes a second magnetic connector disposed at the top of the pen barrel, the second magnetic connector being used to temporarily store the unused split multi-electrode module; the probe magnetic sleep chamber also includes a protective top cover that snaps into the second magnetic connector.

[0015] Furthermore, a water storage tank is embedded in the outer top of the protective cover.

[0016] Furthermore, the pen barrel is equipped with a display screen and a switch button.

[0017] Furthermore, the pen barrel is wrapped with a silicone anti-slip layer in the circumferential direction.

[0018] The beneficial effects of this utility model are as follows:

[0019] The quick-change telescopic mechanism of the probe makes the length of the water quality test pen adjustable. Through the full thread coverage of the connecting rod and the cooperation of the axial adjustment ring, the probe can be adjusted in micron-level steps to meet the needs of different water depths. When the pitch is 1mm, the probe can be extended or retracted by about 0.0417mm for every 15° rotation of the rotating ring, which is better than the ±1mm error of the traditional snap-on positioning.

[0020] The split-type multi-electrode module enables the device to detect at least two water quality parameters, reducing costs compared to the traditional integrated design, and eliminating the need to scrap the entire unit when a single electrode fails; the silicone anti-slip layer on the outer shell improves stability when operating with wet hands.

[0021] The design of the water storage tank enables point sampling and steady-state detection in confined spaces such as pipelines in field environments. Attached Figure Description

[0032] Example

[0033] like Figure 1-6 As shown, this embodiment discloses a portable multifunctional water quality testing pen, which includes a pen barrel 1, a probe quick-change telescopic mechanism 2, a split multi-electrode module, and a probe magnetic dormancy chamber 3. The split multi-electrode module includes an OPR probe 4 and a pH probe 5. The probe magnetic dormancy chamber 3 is located at the top of the water quality testing pen. The probe quick-change telescopic mechanism 2 is located at the bottom of the water quality testing pen. In this application, when it is necessary to measure oxidation-reduction potential and indirectly indicate disinfection effect and pollutant degradation status, the OPR probe 4 can be installed on the first magnetic connector 14 of the probe quick-change telescopic mechanism 2, and the pH probe 5 can be installed in the probe magnetic dormancy chamber 3 to prevent damage from collision; when it is necessary to determine the acidity, neutrality, or alkalinity of the water body, the positions of the two can be interchanged.

[0034] The probe quick-change telescopic mechanism 2 includes a groove 6 embedded in the side of the pen barrel 1, a connecting rod 7, and an axial adjusting ring 8. Two first planes 9 are provided on the groove 6, which are parallel to each other and perpendicular to the direction of the pen barrel 1. A first through hole 10 is provided at the same height on both first planes 9. A second through hole 11 is provided on the bottom end face of the pen barrel 1. Both the first through holes 10 and the second through hole 11 are at the same height, and both are threaded holes.

[0035] The side of the connecting rod 7 is covered with continuous threads. The connecting rod 7 passes through the second through hole 11 and the two first through holes 10 in sequence to be rotatably mounted on the bottom end of the pen barrel 1. At the same time, the end of the connecting rod 7 is exposed on the outer bottom of the pen barrel 1. The axial adjustment ring 8 is a hollow cylindrical structure with internal threads, and the axial adjustment ring 8 is threaded onto the connecting rod 7 at the position of the groove 6.

[0036] The connecting rod 7 includes a first rod body 12 and a second rod body 13 welded together in sequence. The second rod body 13 has a hollow structure. A first magnetic connector 14 is provided on the first rod body 12. The first magnetic connector 14 is used to connect a split electrode module. In this application, a probe quick-change telescopic mechanism 2 is provided. The axial adjustment ring 8, which is locked in the groove 6, is rotated clockwise or counterclockwise. The rotation of the axial adjustment ring 8 causes the connecting rod 7, which is threaded to it, to move away from or towards the pen barrel 1, thereby adjusting the overall length of the water quality testing pen.

[0037] The probe magnetic dormancy compartment 3 includes a second magnetic connector 15 disposed at the top of the pen barrel 1. The second magnetic connector 15 is used to temporarily store unused OPR probes 4 or PH probes 5. The probe magnetic dormancy compartment 3 also includes a protective top cover 16 that snaps into the second magnetic connector 15. A protective cover can also be provided at the bottom of the water quality testing pen, but since the position of the connecting rod 7 can be moved by rotating the axial adjustment ring 8 in this application, thereby causing the probe at the end of the connecting rod 7 to retract into the water quality testing pen, which also has a protective function, it is not specifically described.

[0038] The protective top cover 16 has a water storage tank 17 embedded in its outer top. When in the field or when it is necessary to test flowing water, the protective top cover 16 can be removed to fill the water storage tank 17 with water. Then, the axial adjustment ring 8 can be rotated to expose the probe for water quality testing. This setup can achieve fixed-point sampling and steady-state testing in confined spaces such as pipelines.

[0039] The pen barrel 1 is equipped with a display screen 18 and a power switch 19. A lithium battery and a processor are also installed inside the pen barrel 1; the lithium battery powers the water quality testing pen. A pH probe 5 or an OPR probe 4 is mounted on a first magnetic connector 14, the other end of which is connected to the processor. The processor analyzes the signals collected by the pH probe 5 or the OPR probe 4 and displays them on the display screen 18. The lithium battery is also connected to the processor via the power switch 19, which turns the water quality testing pen on or off. However, since this application primarily focuses on protecting the extension and retraction of the water quality testing pen and providing technical solutions for at least two types of water quality testing, the above is not the main technical problem addressed by this application. Furthermore, the principle of this water quality testing pen has already been disclosed in the prior art, therefore, it will not be elaborated upon further here.

[0040] The pen barrel 1 is wrapped with a silicone anti-slip layer 20 in the circumferential direction to increase friction and improve stability when operating with wet hands.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
