Description

Technical Field

[0001] This utility model relates to the field of water quality analyzer cleaning technology, and in particular to a residual liquid adsorption device for water quality analyzers. Background Technology

[0002] A water quality analyzer is an instrument used to detect and analyze various parameters in water samples to ensure that the water quality meets specific standards or requirements. It can measure a variety of water quality indicators, including but not limited to pH, dissolved oxygen, turbidity, conductivity, total dissolved solids (TDS), residual chlorine, hardness, ammonia nitrogen, nitrate, and phosphate. Depending on the application and testing needs, water quality analyzers can be divided into two types: laboratory-grade and portable. Laboratory-grade water quality analyzers typically have high accuracy and stability, enabling complex analyses and long-term monitoring. Portable water quality analyzers are easy to carry and can be quickly used for on-site water quality testing, suitable for emergency testing, field operations, environmental monitoring, and other similar situations. The operation of a water quality analyzer generally includes sampling, calibration, measurement, and data analysis. Some advanced water quality analyzers are equipped with automatic calibration and data logging functions, providing real-time monitoring and long-term data recording, facilitating trend analysis and decision support for users.

[0003] Water quality analyzers do indeed have the problem of residual liquid on their inner walls after use. If the instrument is not thoroughly cleaned after testing different water samples, the residual sample components may mix into the next water sample, leading to inaccurate test results. For example, if the previous water sample contained a high concentration of a certain metal ion, these ions may remain in the instrument's detection cell. In the next test, these residual ions may be incorrectly included in the test results of the new water sample, causing the detected value of that metal ion in the new water sample to be higher. Similarly, if the residue can react chemically with the test reagents, it may consume the reagents and change the stoichiometric relationship of the reaction, thus causing the detected substance content to differ from the actual value.

[0004] Some residual liquids are quite stubborn and difficult to clean with conventional cleaning solutions. These residues may adhere to the inner walls of the instrument, affecting not only the accuracy of the detection but also potentially damaging its performance. For example, if the optical components of the instrument are covered with dust or stains, it will affect light transmittance and detection sensitivity. For instruments that use chemical reagents for detection, if there are unwashed residual reagents or other substances on the instrument surface, it may alter the reagent concentration or reaction environment, resulting in inconsistent reaction degrees between the reagent and the water sample in each detection, thus affecting the repeatability and reproducibility of the detection results. Utility Model Content

[0005] The main objective of this invention is to provide a residual liquid adsorption device for a water quality analyzer, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A residual liquid adsorption device for a water quality analyzer includes a detection chamber, an inlet and outlet, a sealing cover, a mounting base, and a cavity. The inlet and outlet are distributed on the upper and lower parts of the side wall of the detection chamber. The sealing cover and the mounting base are installed at the upper and lower ends of the detection chamber. The interior of the detection chamber is a cavity for storing the water to be tested by the water quality analyzer.

[0008] A connecting pipe is installed in the middle of the side wall of the detection chamber, and a docking cover is installed at the opening of the connecting pipe. An air pipe is connected to the inner end of the docking cover. A telescopic hose is connected to the inner end of the air pipe, and a telescopic expansion airbag is connected to the inner end of the telescopic expansion airbag. A telescopic adsorption sponge is connected to the outer wall of the telescopic expansion airbag. The telescopic adsorption sponge is placed in the cavity through the telescopic expansion airbag, and the residual liquid on the inner wall of the cavity is adsorbed.

[0009] The lower end of the docking cover is provided with a fixed seat, and an air pump is installed on the seat body of the fixed seat. The air pump is connected to an air pipe and performs inflation and deflation operations on the telescopic inflatable airbag.

[0010] As a preferred embodiment of this application, the air tube is fixed to the docking cover with adhesive, and a sealant is provided at the connection between the air tube and the docking cover. The air tube and the telescopic hose are designed as an integral part. The telescopic hose is divided into a pleated part and a connecting part. The connecting part is located at both ends of the pleated part. The pleated part expands and contracts as the air pump inflates and deflates.

[0011] As a preferred embodiment of this application, the end face of the docking cover is provided with multiple mounting holes, which are distributed in a ring on the docking cover. The docking cover and the connecting pipe are fixed by connecting flanges, bolts, and nuts.

[0012] As a preferred embodiment of this application, the telescopic hose and the telescopic inflatable airbag are designed as an integral unit. The telescopic inflatable airbag is spherical in shape. When the telescopic inflatable airbag is fully contracted, it is placed at the connection between the connecting pipe and the cavity. A sealing ring is fitted between the telescopic inflatable airbag and the telescopic hose. The sealing ring contacts the inner retaining ring of the connecting pipe to achieve a sealing operation.

[0013] As a preferred embodiment of this application, the telescopic inflatable airbag is adapted to the telescopic absorbent sponge, the telescopic absorbent sponge has an arc-shaped design, and the folds of the telescopic absorbent sponge are adapted to the folds of the telescopic inflatable airbag.

[0014] As a preferred embodiment of this application, the inner wall of the stretchable absorbent sponge is connected with multiple elastic bands, which are distributed in a dotted pattern. The elastic bands are heat-fused and fixed to the stretchable expansion airbag, and the stretchable absorbent sponge is contracted into the folds of the stretchable expansion airbag through the elastic bands.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By expanding and contracting the telescopic inflatable air bladder, the telescopic adsorption sponge efficiently adsorbs residual liquid on the inner wall of the cavity, resulting in a significant cleaning effect and ensuring the accuracy and stability of the water quality analyzer. The mechanism is rationally designed and easy to operate; simply starting the air pump to inflate and deflate the telescopic inflatable air bladder and the telescopic adsorption sponge eliminates the need for manual cleaning, thus improving work efficiency.

[0017] The telescopic absorbent sponge is secured to the telescopic expansion airbag with an elastic band, facilitating disassembly and replacement and reducing maintenance costs. Simultaneously, the sponge's curved design and pleats match the pleated shape of the telescopic expansion airbag, improving adsorption efficiency and extending its service life. When fully retracted, the telescopic expansion airbag is positioned at the connection between the connecting pipe and the cavity, minimizing its footprint and making the entire device more compact, easy to carry, and easy to store.

[0018] The components of the device, such as the connecting cover, connecting pipe, and telescopic hose, adopt a robust connection method, such as connecting flanges, bolts, and nuts, which enhances the structural strength of the device and ensures that it will not be damaged by vibration or external force during the cleaning process.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1- Figure 4 As shown, a residual liquid adsorption device for a water quality analyzer mainly consists of a detection chamber 1, inlet and outlet 2, sealing cover 3, mounting base 4, and cavity 5. The inlet and outlet 2 are respectively located on the upper and lower parts of the side wall of the detection chamber 1 to facilitate the entry and exit of liquid. The sealing cover 3 and mounting base 4 are respectively installed at the upper and lower ends of the detection chamber 1 to ensure the device's airtightness. The interior of the detection chamber 1 is designed as a cavity 5, whose main function is to store the water sample to be tested by the water quality monitor.

[0026] A connecting pipe 6 is specially designed and installed in the middle of the side wall of the testing chamber 1. A docking cover 7 is installed at the opening of the connecting pipe 6, and the inner end of the docking cover 7 is connected to an air pipe 9. The other end of the air pipe 9 is connected to a telescopic flexible hose 10, and the inner end of the telescopic flexible hose 10 is connected to a telescopic inflatable airbag 11. A telescopic absorbent sponge 12 is fixed to the outer wall of the telescopic inflatable airbag 11. By expanding and contracting the telescopic inflatable airbag 11, the telescopic absorbent sponge 12 can be placed in the cavity 5, thereby effectively adsorbing residual liquid on the inner wall of the cavity 5.

[0027] To enable the inflation and deflation of the telescopic inflatable airbag 11, a fixing seat 13 is specially provided at the lower end of the docking cover 7, and an air pump 14 is installed on the fixing seat 13. The air pump 14 is connected to the telescopic inflatable airbag 11 through the air pipe 9, thereby realizing the inflation and deflation control of the telescopic inflatable airbag 11.

[0028] The air tube 9 is fixed to the docking cover 7 with adhesive to ensure a stable connection. A sealant is also applied at the connection between the air tube 9 and the docking cover 7 to prevent gas leakage. Furthermore, the air tube 9 and the telescopic hose 10 are integrated into a single unit. The telescopic hose 10 consists of a pleated section and a connecting section, with the connecting section located at both ends of the pleated section. The pleated section can expand and contract with the inflation and deflation of the air pump 14, thereby driving the corresponding movements of the telescopic inflatable airbag 11 and the telescopic absorbent sponge 12.

[0029] The end face of the docking cover 7 has multiple mounting holes 8, which are distributed in a ring on the docking cover 7 to ensure the stability and reliability of the device. The docking cover 7 and the docking pipe 6 are fixed together by fasteners such as connecting flanges, bolts, and nuts, which further enhances the structural strength of the device.

[0030] The telescopic hose 10 and the telescopic inflatable airbag 11 are integrated into one piece. The telescopic inflatable airbag 11 has a spherical design to better fit the space of the cavity 5. When the telescopic inflatable airbag 11 is fully retracted, it will be positioned at the connection between the connecting pipe 6 and the cavity 5 to minimize space occupation. A sealing ring is fitted at the connection between the telescopic inflatable airbag 11 and the telescopic hose 10. This sealing ring contacts the retaining ring inside the connecting pipe 6 to achieve a good sealing effect.

[0031] The telescopic expansion airbag 11 and the telescopic adsorption sponge 12 are designed to be compatible. The telescopic adsorption sponge 12 has an arc-shaped design, and its folds are adapted to the folds of the telescopic expansion airbag 11 to improve adsorption efficiency. Multiple elastic bands are connected to the inner wall of the telescopic adsorption sponge 12. These elastic bands are distributed in a dotted pattern and are fixed to the telescopic expansion airbag 11 by heat fusion. The function of the elastic bands is to allow the telescopic adsorption sponge 12 to contract and fit into the folds of the telescopic expansion airbag 11, thus facilitating cleaning and replacement after adsorbing residual liquid.

[0032] Assembly Process: Install inlet and outlet 2 on the upper and lower parts of the side wall of the detection chamber 1 to ensure smooth liquid flow. Install sealing caps 3 and mounting bases 4 at the upper and lower ends of the detection chamber 1 to ensure the device's airtightness. A specially designed and installed connecting pipe 6 is installed in the middle of the side wall of the detection chamber 1, ensuring that a docking cap 7 is installed at its opening. Connect the air pipe 9 to the inner end of the docking cap 7, ensuring the connection is secured with adhesive and sealed with sealant to prevent gas leakage. Connect the inner end of the telescopic hose 10 to the air pipe 9, and connect the other end of the telescopic hose 10 to the telescopic expansion airbag 11. Fix the telescopic adsorption sponge 12 to the outer wall of the telescopic expansion airbag 11, ensuring it can adsorb as the airbag expands and contracts. Install a mounting base 13 at the lower end of the docking cap 7, and install an air pump 14 on the mounting base 13, ensuring that the air pump 14 is connected to the telescopic expansion airbag 11 via the air pipe 9. Multiple mounting holes 8 are made on the end face of the docking cover 7, and the docking cover 7 is fixed to the docking pipe 6 by fasteners such as connecting flanges, bolts, and nuts to enhance the structural strength of the device. Ensure that the telescopic hose 10 and the telescopic inflatable airbag 11 are designed as a single unit, and that the telescopic inflatable airbag 11 has a spherical design. Multiple elastic bands connecting the inner wall of the telescopic absorbent sponge 12 are fixed to the telescopic inflatable airbag 11 by heat fusion.

[0033] Residual liquid adsorption cleaning process: Start the air pump 14 to inflate the telescopic expansion airbag 11, causing it to expand. The inflated telescopic expansion airbag 11 pushes the telescopic adsorption sponge 12 outwards, making it adhere to the inner wall of the cavity 5. When the telescopic adsorption sponge 12 is completely adhered to the inner wall of the cavity 5, the residual liquid is adsorbed on the sponge surface. Turn off the air pump 14, causing the telescopic expansion airbag 11 to contract, simultaneously causing the telescopic adsorption sponge 12 to contract as well. The contracted telescopic adsorption sponge 12 detaches from the inner wall of the cavity 5, concentrating the adsorbed residual liquid on the sponge surface. Remove the telescopic adsorption sponge 12 for cleaning or replacement. If necessary, repeat the above steps multiple times for adsorption cleaning until the inner wall of the cavity 5 is clean and free of residual liquid.
