Description

Technical Field

[0001] This utility model relates to the field of water source testing, and in particular to a sealing structure for a portable water quality testing device. Background Technology

[0002] With the development of environmental monitoring and water resource management, the demand for rapid on-site water quality testing is increasing. The sealed structure of portable water quality testing devices can adapt to various harsh environments, ensuring that the internal testing components are not affected by external environmental factors.

[0003] Early, simple portable water quality testing devices used a simple rubber ring sealing structure, which would deform over time, leading to a decrease in sealing performance. Current sealing structures enhance sealing through a tight fit between the sealing ring and the sealing cap. After water quality testing, residual water is cleaned with pure distilled water to avoid introducing new impurities that could affect subsequent test results. However, some water residue remains inside the instrument after cleaning. This residue can breed microorganisms that multiply rapidly, contaminating subsequent water samples and affecting the accuracy of test results. Furthermore, it can corrode the sealing structure itself, reducing sealing performance and shortening the device's lifespan. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sealing structure for a portable water quality testing device, which aims to improve the problem of water stains remaining after cleaning in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a sealing structure for a portable water quality testing device, comprising a base and a sealing cover. A button is provided on the top of the sealing cover, and a round rod is rotatably connected to the bottom of the button. A threaded groove is formed on the outer wall of the round rod, and the outer wall of the threaded groove is threadedly connected to the inner wall of the sealing cover. A fixing block is fixedly connected to the bottom of the round rod, and a spring is fixedly connected to the bottom of the fixing block. A Velcro fastener is fixedly connected to the bottom of the spring, and a sponge block is provided at the bottom of the Velcro fastener. The sponge block engages with the Velcro fastener. A groove is formed on the inner wall of the sealing cover. A round block is fixedly connected to the front top of the base. A sealing mechanism is provided on the inner wall of the sealing cover, and the sealing mechanism is used to increase the sealing performance between the instrument and the sealing cover.

[0006] As a further description of the above technical solution:

[0007] The sealing mechanism includes a partition plate, the bottom of which is fixedly connected to the inner wall of the base. The inner wall of the base is provided with compression cotton. Multiple anti-slip protrusions are fixedly connected to the outer wall of the partition plate. A limiting ring is fixedly connected to the bottom of the sealing cover. A magnetic ring is provided on the inner wall of the limiting ring, the top of which is fixedly connected to the sealing cover. Multiple anti-slip recesses are provided on the inner wall of the limiting ring.

[0008] As a further description of the above technical solution:

[0009] The bottom of the base is fixedly connected to a bottom cover, and a rotating column is fixedly connected to the rear side of the outer wall of the bottom cover. A drop-proof cover is rotatably connected to the outer wall of the rotating column.

[0010] As a further description of the above technical solution:

[0011] A concave block is fixedly connected to the top of the outer wall of the anti-fall cover, and a locking block is fixedly connected to the front side of the bottom cover. The concave block and the locking block engage with each other.

[0012] As a further description of the above technical solution:

[0013] An interface is provided on the right side of the outer wall of the base, and a warning light is fixedly connected to the top left side of the base.

[0014] As a further description of the above technical solution:

[0015] A fixing post is fixedly connected to the right side of the bottom cover, and a ring buckle is fixedly connected to the right side of the outer wall of the fixing post.

[0016] As a further description of the above technical solution:

[0017] Multiple buttons are fixedly connected to the top front side of the circular block, and a display screen is fixedly connected to the top rear side of the circular block.

[0018] As a further description of the above technical solution:

[0019] The inner wall of the partition is rounded, and the inner wall of the sealing cover is the same size as the outer wall of the partition.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, after the water sample test is completed, the sealing cap is removed, the water sample in the base is poured out, and the sample is rinsed with distilled water. Then, the sealing cap is put back on, the top button is pressed, and the round rod is rotated and moved downwards. This causes the fixing block, spring, and sponge block to move downwards in sequence. When the sponge block contacts the bottom of the instrument, it absorbs residual water stains. Excess pressure is converted into elastic potential energy by the spring and stored. When the button is released, the spring returns to its original state, thus avoiding damage to the instrument, ensuring that the sponge block absorbs water efficiently, and preventing water stains from causing microbial growth.

[0022] 2. In this utility model, when testing a water sample, the water sample is poured into the partition on the inner wall of the base. The sealing cover is then placed on top, causing the limiting ring to move downwards. When the limiting ring contacts the partition, the anti-slip concave block on its inner wall engages with the anti-slip protrusion on the outer wall of the partition. At the same time, the magnetic ring attracts the partition, making the sealing cover fit tightly against the instrument, forming a closed space. During testing, the squeezing cotton at the top of the inner wall of the base squeezes the partition, filling tiny gaps, preventing air and impurities from entering and water sample leakage, enhancing the sealing performance, and ensuring accurate and reliable test data.

[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] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a sealed structure for a portable water quality testing device, comprising a base 1 and a sealing cover 3. A button 4 is located on the top of the sealing cover 3, serving as a start switch for controlling the cleaning and drying functions. A round rod 5 is rotatably connected to the bottom of the button 4, transmitting power. A threaded groove 6 is formed on the outer wall of the round rod 5, controlling linear motion. The outer wall of the threaded groove 6 is threadedly connected to the inner wall of the sealing cover 3. A fixing block 7 is fixedly connected to the bottom of the round rod 5, enabling synchronous and stable movement of the components. The bottom of the fixing block 7... A spring 8 is fixedly connected, and the spring 8 has an elastic buffering function. A Velcro 9 is fixedly connected to the bottom of the spring 8. The Velcro 9 can be replaced in time when the water absorption capacity decreases after multiple uses. A sponge block 10 is set at the bottom of the Velcro 9. The sponge block 10 has a water absorption function. The sponge block 10 and the Velcro 9 are locked together. A groove 11 is opened on the inner wall of the sealing cover 3. The groove 11 enhances the sealing effect. A circular block 12 is fixedly connected to the top front side of the base 1. A sealing mechanism 2 is set on the inner wall of the sealing cover 3. The sealing mechanism 2 is used to increase the sealing between the instrument and the sealing cover 3.

[0032] Specifically, after the water sample test is completed, remove the sealing cap 3, pour out the water sample in the base 1, rinse with distilled water to remove residual impurities, then put the sealing cap 3 back on, press the top button 4 to drive the round rod 5 to rotate and move downwards, which in turn drives the fixing block 7, spring 8 and sponge block 10 to move down. When the sponge block 10 contacts the bottom of the instrument, it absorbs residual water stains. Excess pressure is converted into elastic potential energy by the spring 8 and stored. Release the button 4, and the spring 8 returns to its original state to avoid damage to the instrument, ensure that the sponge block 10 absorbs water efficiently, and prevent water stains from causing microbial growth.

[0033] Reference Figure 3 , Figure 4 and Figure 5The sealing mechanism 2 includes a partition 201. The bottom of the partition 201 is fixedly connected to the inner wall of the base 1. The inner wall of the base 1 is provided with compression cotton 203, which prevents water leakage and enhances the sealing performance. The outer wall of the partition 201 is fixedly connected with multiple anti-slip protrusions 202. The anti-slip protrusions 202 and anti-slip concave blocks 206 have friction and stability to prevent relative displacement. The bottom of the sealing cover 3 is fixedly connected with a limiting ring 205, which seals the stability of the detection environment. The inner wall of the limiting ring 205 is provided with a magnetic ring 204, which connects the magnetic ring 204 to the instrument body and improves the sealing effect. The top of the magnetic ring 204 is fixedly connected to the sealing cover 3. The inner wall of the limiting ring 205 is provided with multiple anti-slip concave blocks 206.

[0034] Specifically, when testing a water sample, the water sample is poured into the partition 201 on the inner wall of the base 1. The sealing cover 3 is then placed on top, causing the limiting ring 205 to move downwards. When the limiting ring 205 contacts the partition 201, the anti-slip concave block 206 on its inner wall engages with the anti-slip protrusion 202 on the outer wall of the partition 201. At the same time, the magnetic ring 204 attracts the partition 201, making the sealing cover 3 fit tightly against the instrument, forming a closed space. During the test, the squeezing cotton 203 at the top of the inner wall of the base 1 squeezes the partition 201, filling tiny gaps, preventing air and impurities from entering and water sample from leaking, enhancing the sealing performance, and ensuring accurate and reliable test data.

[0035] Reference Figure 1 and Figure 2 The bottom of the base 1 is fixedly connected to the bottom cover 15, which provides stable support for the instrument. The outer wall of the bottom cover 15 is fixedly connected to the rear side of the outer wall of the bottom cover 15. The rotating column 17 is the pivot for rotation. The outer wall of the rotating column 17 is rotatably connected to the anti-drop cover 16, which buffers the impact force and protects the precision components inside the instrument. The top of the outer wall of the anti-drop cover 16 is fixedly connected to the concave block 18. The front side of the bottom cover 15 is fixedly connected to the locking block 19. The locking block 19 and the concave block 18 are engaged to fix and prevent drops. The concave block 18 and the locking block 19 are engaged. The right side of the outer wall of the base 1 has an interface 21, which ensures the continuous operation of the equipment. The top left side of the base 1 is fixedly connected to the warning light 20, which is associated with the internal detection system of the device.

[0036] Specifically, when the instrument is no longer in use, the bottom cover 15 is connected to the base 1 itself. First, the anti-drop cover 16 is rotated around the rotating column 17 to make the anti-drop cover 16 fit against the bottom cover 15. The internal components of the instrument are protected by the engagement of the concave block 18 and the locking block 19, reducing damage caused by drops. The data transmission line can be connected through the interface 21 to transmit the water quality test data stored in the detection device to a computer or other storage device for further data analysis and processing. It can also be connected to the charging cable to charge the built-in battery of the device, ensuring continuous operation of the device in different environments. When an abnormality occurs during the detection process, the warning light 20 will light up red to issue a warning signal. When the yellow light is on, it indicates that the battery is low.

[0037] Reference Figure 1 , Figure 2 and Figure 4 A fixing post 22 is fixedly connected to the right side of the bottom cover 15. The fixing post 22 is used for fixing. A ring buckle 23 is fixedly connected to the right side of the outer wall of the fixing post 22. The ring buckle 23 is used for carrying and operation. Multiple buttons 13 are fixedly connected to the top front side of the circular block 12. The buttons 13 are used to start the detection program and switch the data display, which facilitates the control of the instrument operation. A display screen 14 is fixedly connected to the top rear side of the circular block 12. The display screen 14 is responsible for displaying detection data, equipment status and operation prompts. The inner wall of the partition 201 is rounded. The inner wall of the sealing cover 3 is the same size as the outer wall of the partition 201.

[0038] Specifically, when the instrument is in hand, fingers are threaded through the ring buckle 23 to secure the instrument more firmly and prevent accidental slippage. The circular block 12 is equipped with multiple buttons 13, which are used to turn the instrument on and off, as well as to operate the detection program and switch the data display mode. The progress and results of the water quality detection are displayed on the screen 14.

[0039] Working principle: After the water sample is tested, remove the sealing cap 3 from the instrument and slowly and thoroughly pour out the water sample from the base 1. Then, slowly pour pure distilled water into the base 1 to rinse away the water sample and impurities. After cleaning, tightly attach the sealing cap 3 to the instrument and press the button 4. The button 4 drives the round rod 5, causing the threaded groove 6 to rotate through the threaded connection of the sealing cap 3. As the round rod 5 rotates downwards, it sequentially drives the fixing block 7, spring 8, and sponge block 10 to move downwards synchronously. When the sponge block 10 rotates and gradually approaches the bottom of the instrument and finally contacts it, it will draw out the water. The instrument collects residual water stains. When the sponge block 10 contacts the bottom, the excess pressure is converted into elastic potential energy and stored by the spring 8. Then, the button 4 is pulled back to its original position. At the same time, the pressure on the spring 8 is released, thus restoring the instrument to its original state. This buffer not only effectively prevents scratches and deformation damage to the bottom of the instrument due to excessive pressure, but also ensures that the spring 8 has low elasticity and will not put excessive pressure on the sponge block 10. This perfectly solves the problem of microbial growth and reproduction caused by water stains inside the instrument, providing a clean and sterile environment for the next test.

[0040] Furthermore, through the sealing mechanism 2, when testing the water sample, the water sample is slowly poured into the interior of the partition 201. The sealing cover 3 drives the limiting ring 205 to move downward. When the limiting ring 205 moves downward to contact the partition 201, the anti-slip concave block 206 on the inner wall of the limiting ring 205 engages with the anti-slip protrusion 202 on the partition 201. At the same time, the magnetic suction ring 204 on the inner wall of the limiting ring 205 is tightly fitted with the partition 201, and the sealing cover 3 is tightly fitted with the instrument, forming a closed testing space. During the testing process, the squeezing cotton 203 at the top of the inner wall of the base 1 will squeeze the partition 201. This squeezing action further fills the existing tiny gaps, preventing external air and impurities from entering the testing space, and also preventing water sample leakage. This greatly enhances the sealing performance of the instrument, thereby effectively improving the accuracy of water sample testing and ensuring the reliability of the test data.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
