Description

Technical Field

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

[0002] In today's society, people are paying increasing attention to water quality safety. Whether it's outdoor adventurers drawing water from natural water sources, households paying attention to the quality of their drinking water, or aquaculture farmers monitoring the aquatic environment in real time, there is an urgent need for convenient and accurate water quality testing methods. Traditional water quality testing methods often rely on professional laboratory equipment, which are complex, time-consuming, and costly, and cannot meet the needs of testing anytime and anywhere. Multifunctional portable water quality testing pens have emerged to address this need. They are lightweight and portable, integrating multiple testing functions, allowing ordinary people to quickly know key indicators of water quality such as pH, dissolved oxygen, and conductivity with simple operation, without the need for professional knowledge, providing timely and reliable water quality information for various water use scenarios.

[0003] Existing multifunctional portable water quality testing pens have certain inconveniences in practical use. When water quality testing is required, users need to remove the pen cap and then insert the probe into the water to complete the test. However, after the test, in order to ensure the accuracy of the next test and the service life of the device, the probe needs to be dried. However, because the testing pen has a protective structure, this part, which is originally intended to protect the probe, becomes an obstacle when wiping. The presence of the protective structure makes the probe part difficult to reach, increasing the difficulty of wiping and making it impossible to dry the probe efficiently and thoroughly. This affects the cleaning and maintenance of the testing pen after use, so improvements and optimizations are needed. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a multifunctional portable water quality testing pen, which has the advantage of being easy to wipe the probe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional portable water quality testing pen, comprising a testing pen, a probe protective cover fixedly mounted on the side of the testing pen, a probe fixedly mounted on the side of the testing pen, a wiping assembly movably sleeved on the outer side of the probe protective cover and located on the side of the testing pen, the wiping assembly including a pen sleeve movably sleeved on the outer side of the probe protective cover, a movable plate movably mounted on the inner side of the pen sleeve, a sponge block snapped into the inner side of the movable plate, an abutment plate movably mounted between the movable plate and the sponge block, a connecting rod fixedly mounted on the side of the abutment plate and passing through the movable plate and the pen sleeve, a rotating disk fixedly mounted at the end of the connecting rod, a spring fixedly connected to the inner side of the movable plate and the pen sleeve, a sponge groove formed on the inner side of the sponge block and corresponding to the probe, a sliding groove formed on the outer surface of the pen sleeve and the sliding groove being L-shaped, and a sliding block fixedly mounted on the outer surface of the movable plate and extending out of the sliding groove.

[0006] As a preferred technical solution of this utility model, the detection pen is fixedly installed with snap-fit ​​components on both sides of its side. The snap-fit ​​components include extension plates fixedly installed on both sides of the detection pen. The extension plates are fixedly installed with protrusions on their sides. The protrusions are fixedly installed with rubber rings at their ends. The outer surface of the pen sleeve is provided with fitting grooves on both sides, and the fitting grooves are provided with snap-fit ​​slots on their inner sides.

[0007] As a preferred technical solution of this utility model, the sponge block, the movable plate and the pen cap are provided with air-drying grooves on their sides, and they fit together.

[0008] As a preferred embodiment of this utility model, the movable plate is in close contact with the inner wall of the pen cap, and the inner diameter of the probe protective cover is smaller than the diameter of the movable plate.

[0009] As a preferred embodiment of this utility model, a hook is fixedly installed on the outer surface of the detection pen, and the hook is hook-shaped.

[0010] As a preferred embodiment of this utility model, flexible protrusions are fixedly installed on both sides of the outer surface of the detection pen, and the flexible protrusions are uniformly spaced.

[0011] As a preferred embodiment of this utility model, the outer surface of the detection pen is provided with a display screen, and a detection button is fixedly installed on the outer surface of the detection pen.

[0012] As a preferred embodiment of this invention, the probe protective cover is annular in shape, and the probe is located inside the probe protective cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model utilizes a sponge groove on the inner side of the sponge block to fully absorb water stains on the outer surface of the probe. After absorption, the sliding block is moved in the opposite direction, and the spring force restores the movable plate and sponge block to their original positions. Compared with traditional devices, this device has several advantages. First, when the operator applies force, the linkage design between the components allows the sponge groove to wrap around the probe. Rotating the rotating disk drives the connecting rod, prompting the sponge groove to fully absorb water stains on the outer surface of the probe, effectively removing water stains. Second, after absorption, moving the sliding block in the opposite direction and utilizing the spring force restores the relevant components to their original positions. The operation is simple. This design overcomes the problem of difficult-to-wipe probes in existing testing pens. It not only dries the probes efficiently and thoroughly but also facilitates cleaning and maintenance of the testing pen after use, ensuring the accuracy of the next test and extending the service life of the equipment.

[0015] 2. This utility model uses external force to make the rubber ring snap into the inner side of the slot. Since the rubber ring is made of rubber, it can increase static friction, making the wiping component snap into place more stably. Compared with traditional devices, this device can easily be moved to both sides by the elasticity of the extension plate, quickly achieving a precise match with the fitting groove, making the docking process efficient and smooth. At the same time, the rubber ring fits tightly into the slot. In particular, the rubber ring is made of rubber, which is not only soft and easy to snap into the inner side of the slot, but also has high static friction due to its natural characteristics, which provides a solid guarantee for the overall snap-in stability, effectively preventing the components from loosening or shifting, and greatly improving the reliability and durability of the connection.

[0025] 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.

[0026] like Figures 1 to 8 As shown, this utility model provides a multifunctional portable water quality testing pen, including a testing pen 1. A probe protective cover 4 is fixedly installed on the side of the testing pen 1, and a probe 5 is fixedly installed on the side of the testing pen 1. A wiping assembly 7 is movably sleeved on the outside of the probe protective cover 4 and located on the side of the testing pen 1. The wiping assembly 7 includes a pen sleeve 701 movably sleeved on the outside of the probe protective cover 4. A movable plate 702 is movably installed on the inside of the pen sleeve 701. A sponge block 703 is snapped into the inside of the movable plate 702. An abutment plate 70 is movably installed between the movable plate 702 and the sponge block 703. 4. A connecting rod 705 is fixedly installed on the side of the abutment plate 704 and the connecting rod 705 passes through the movable plate 702 and the pen cap 701. A rotating disk 706 is fixedly installed at the end of the connecting rod 705. A spring 710 is fixedly connected to the inner side of the movable plate 702 and the pen cap 701. A sponge groove 707 is opened on the inner side of the sponge block 703 and the sponge groove 707 corresponds to the probe 5. A sliding groove 708 is opened on the outer surface of the pen cap 701 and the sliding groove 708 is L-shaped. A sliding block 709 is fixedly installed on the outer surface of the movable plate 702 and extends out of the sliding groove 708.

[0027] When the operator applies downward force to the sliding block 709, it will slide downward along the sliding groove 708. Simultaneously, the sliding block 709 will cause the movable plate 702 to shift downward, resulting in elastic deformation of the spring 710. As the movable plate 702 moves downward, it will cause the sponge block 703 to move downward. When the sponge block 703 moves downward, the sponge groove 707 will wrap around the probe 5, causing the sliding block 709 to slide towards the sliding groove 708, thus limiting its position. At this point, by rotating the rotating disk 706, when the rotating disk 706 rotates... This will cause the connecting rod 705 to start rotating. When the connecting rod 705 starts rotating, it will abut against the sponge block 703 to generate friction. At this time, the friction is not enough to completely rotate the sponge block 703, so the sponge block 703 can only rotate incompletely left and right. This allows the sponge groove 707 on the inner side of the sponge block 703 to fully absorb the water stains on the outer surface of the probe 5. After the water stains are absorbed, the sliding block 709 is pushed in the opposite direction, which will cause the movable plate 702 and the sponge block 703 to return to their original positions through the elastic force of the spring 710, making it easier to remove the water stains on the outer surface of the probe 5.

[0028] The sponge groove 707 inside the sponge block 703 fully absorbs water stains on the outer surface of the probe 5. After absorption, the sliding block 709 is moved in the opposite direction, and the elastic force of the spring 710 will cause the movable plate 702 and the sponge block 703 to return to their original positions. Compared with traditional devices, this device has several advantages. First, when the operator applies force, the linkage design between the components allows the sponge groove 707 to wrap around the probe 5. Rotating the rotating disk 706 can drive the connecting rod 705, prompting the sponge groove 707 to fully absorb water stains on the outer surface of the probe 5, effectively removing water stains. Second, after absorption, moving the sliding block 709 in the opposite direction and using the elastic force of the spring 710 can reset the relevant components. The operation is simple. This design overcomes the problem of difficult-to-wipe probes in existing testing pens. It can not only efficiently and thoroughly dry the probe, but also facilitate the cleaning and maintenance of the testing pen after use, ensuring the accuracy of the next test and the service life of the equipment.

[0029] The detection pen 1 has a snap-fit ​​assembly 6 fixedly installed on both sides of its side. The snap-fit ​​assembly 6 includes an extension plate 601 fixedly installed on both sides of the detection pen 1. The extension plate 601 has a protrusion 602 fixedly installed on its side. The protrusion 602 has a rubber ring 603 fixedly installed at its end. The pen sleeve 701 has a fitting groove 604 on both sides of its outer surface. The fitting groove 604 has a snap-fit ​​groove 605 on its inner side.

[0030] When the staff needs to engage the wiping component 7, the extension plate 601 is elastic, allowing it to be moved to both sides, thus matching the extension plate 601 with the fitting groove 604. One end of the extension plate 601 abuts against one end of the fitting groove 604, at which point the rubber ring 603 matches the slot 605. Then, external force is applied to make the rubber ring 603 engage inside the slot 605. Since the rubber ring 603 is made of rubber, it increases static friction, making the engagement of the wiping component 7 more stable.

[0031] External force causes the rubber ring 603 to engage with the inside of the slot 605. Because the rubber ring 603 is made of rubber, it increases static friction, making the wiping assembly 7 more securely engaged. Compared to traditional devices, this device, thanks to the elasticity of the extension plate 601, can easily be moved to both sides, quickly achieving precise matching with the fitting groove 604, making the docking process efficient and smooth. Simultaneously, the rubber ring 603 fits tightly with the slot 605. In particular, the rubber ring 603, being made of rubber, is not only soft and easy to engage with the inside of the slot 605, but its inherent high static friction provides a solid guarantee for the overall engagement stability, effectively preventing loosening or displacement of components and greatly improving the reliability and durability of the connection.

[0032] Among them, the sponge block 703, the movable plate 702 and the pen cap 701 have air-drying grooves 711 on their sides, and they fit together.

[0033] The sponge block 703, the movable plate 702, and the pen cap 701 have air-drying grooves 711 on their sides, which are in a corresponding manner, so that the sponge block 703 can be quickly air-dried naturally after use through the air-drying grooves 711.

[0034] The movable plate 702 is in close contact with the inner wall of the pen cap 701, and the inner diameter of the probe protective cover 4 is smaller than the diameter of the movable plate 702.

[0035] By making the inner diameter of the probe protective cover 4 smaller than the diameter of the movable plate 702, the movable plate 702 can effectively limit the probe protective cover 4 when it moves downward, thus preventing damage to the probe 5 when the movable plate 702 moves downward.

[0036] The outer surface of the detection pen 1 is fixedly equipped with a hook 8, and the hook 8 is hook-shaped.

[0037] The hook 8 is hook-shaped, which makes it easier to expand the placement scenario of the detection pen 1.

[0038] Among them, flexible protrusions 9 are fixedly installed on both sides of the outer surface of the detection pen 1, and the flexible protrusions 9 are uniformly spaced.

[0039] The flexible protrusions 9 are evenly spaced, which can increase the comfort of the staff when using them.

[0040] The outer surface of the testing pen 1 is provided with a display screen 2, and a testing button 3 is fixedly installed on the outer surface of the testing pen 1.

[0041] A detection button 3 is fixedly installed on the outer surface of the detection pen 1, which makes it easy to start and stop the detection of the probe 5. At the same time, the display screen 2 makes it easy to observe the detected data, and the probe 5 and the detection button 3 are electrically connected.

[0042] The probe shield 4 is annular in shape, and the probe 5 is located inside the probe shield 4.

[0043] With the probe shield 4 being ring-shaped and the probe 5 located inside the probe shield 4, the probe 5 can be effectively physically protected.

[0044] Working principle and usage process of this utility model:

[0045] When the operator applies downward force to the sliding block 709, it will slide downward along the sliding groove 708. Simultaneously, the sliding block 709 will cause the movable plate 702 to shift downward, resulting in elastic deformation of the spring 710. As the movable plate 702 moves downward, it will cause the sponge block 703 to move downward. When the sponge block 703 moves downward, the sponge groove 707 will wrap around the probe 5, causing the sliding block 709 to slide towards the sliding groove 708, thus limiting its position. At this point, by rotating the rotating disk 706, when the rotating disk 706 rotates... This will cause the connecting rod 705 to start rotating. When the connecting rod 705 starts rotating, it will abut against the sponge block 703 to generate friction. At this time, the friction is not enough to completely rotate the sponge block 703, so the sponge block 703 can only rotate incompletely left and right. This allows the sponge groove 707 on the inner side of the sponge block 703 to fully absorb the water stains on the outer surface of the probe 5. After the water stains are absorbed, the sliding block 709 is pushed in the opposite direction, which will cause the movable plate 702 and the sponge block 703 to return to their original positions through the elastic force of the spring 710, making it easier to remove the water stains on the outer surface of the probe 5.

[0046] When the staff needs to engage the wiping component 7, the extension plate 601 is elastic, allowing it to be moved to both sides, thus matching the extension plate 601 with the fitting groove 604. One end of the extension plate 601 abuts against one end of the fitting groove 604, at which point the rubber ring 603 matches the slot 605. Then, external force is applied to make the rubber ring 603 engage inside the slot 605. Since the rubber ring 603 is made of rubber, it increases static friction, making the engagement of the wiping component 7 more stable.
