[0044] Example 1

[0045] In view of the aforementioned deficiencies in the prior art, the applicant, drawing upon years of extensive practical experience and expertise in design and manufacturing in this field, combined with the application of academic theory, has actively engaged in research and innovation, hoping to create a technology that can address these deficiencies. Through continuous research and design, and through repeated trial production and improvements, the applicant has finally created the present utility model, which possesses truly practical value.

[0046] Please refer to Figure 1-3 The present invention provides a standard release container designed to accurately determine the gas release rate standard. Its unique structural design and clear functions make it possible to accurately determine the gas release rate standard. The container primarily consists of two components: a bottle body 1 and a bottle cap 2. The two components are connected by a detachable design, facilitating operation and maintenance while ensuring the container's tightness and reusability.

[0047] The bottle body 1, the main body of the container, is meticulously designed to safely and stably contain various reference liquids, including but not limited to highly volatile chemicals like toluene and formaldehyde. This design prevents accidental leakage of reference liquids during storage, ensuring a safe and pure laboratory environment.

[0048] The bottle cap 2 is one of the innovative highlights of this utility model, featuring an ingenious opening 3. This opening has been precisely calculated and tested to ensure that when a standard liquid evaporates under specific temperature, humidity, and atmospheric pressure conditions, the gas generated is released through the opening into the external environment at a constant and predictable rate. This feature provides a solid foundation for standardized measurement of gas release rates in scientific research and industrial production.

[0049] The standard release container of this utility model successfully establishes a standardized reference benchmark for gas release rates. This benchmark is not only highly scientific and reasonable, but also serves as a core comparison basis during the release chamber qualification testing process. During the testing process, the release chamber under test and the standard release container are placed under the same or similar environmental conditions. By comparing the gas release rates and characteristics between the two, the performance and compliance of the release chamber under test can be intuitively evaluated.

[0050] In summary, this new standard release container, with its unique design and superior performance, provides strong technical support and assurance for scientific research, industrial production, and quality control in related fields. It not only simplifies the gas release rate measurement process, improving the accuracy and reliability of measurement results, but also promotes the unification and standardization of technical standards in related fields.

[0051] In one embodiment of this invention, special emphasis is placed on the sealed connection design between the bottle body 1 and the bottle cap 2. This sealed connection not only ensures the tightness of the container when loaded with the standard liquid, effectively prevents accidental leakage of the liquid during storage or transportation, but also further ensures the purity and safety of the experimental or testing environment.

[0052] To achieve an efficient sealing effect, various technical means may be adopted, such as a threaded fit with a sealing gasket design, or a bottle cap made of an elastic material that generates sufficient sealing force during the tightening process. These designs can ensure that when the bottle cap 2 is properly installed on the bottle body 1, the contact surface between the two can form a tight seal, preventing any unintended penetration of gas or liquid.

[0053] The sealed connection also provides strong support for precise control of the gas release rate. Since the evaporation rate of the standard liquid is affected by various factors such as ambient temperature, humidity, and atmospheric pressure, the sealed connection can reduce the interference of external environmental factors on the internal environment of the container, thus ensuring accurate measurement of the gas release rate under constant conditions.

[0054] In one implementation of this embodiment, the standard release container is endowed with higher flexibility and adjustability, which is mainly due to the newly added capillary tube 4.

[0055] Specifically, the capillary tube 4 is cleverly designed to be inserted into the opening 3 on the bottle cap 2. The innovation of this design is that it allows the gas release rate to be precisely controlled by adjusting the length of the capillary tube 4 itself without replacing the entire bottle cap.

[0056] The gas release rate is closely related to the pore size and depth. In traditional designs, the thickness of the bottle cap is often constant, which limits the adjustable range of the pore depth. This embodiment cleverly overcomes this limitation by introducing a capillary tube 4. Users can select the appropriate length of capillary tube 4 and insert it into the opening 3 to achieve the desired pore depth, based on the specific needs of the experiment or test, thereby fine-tuning the gas release rate.

[0057] This design also offers operational convenience. Without having to replace the bottle cap, users can quickly and easily adjust the gas release rate without compromising the container's seal. This not only saves experimental preparation time, but also reduces costs and improves work efficiency.

[0058] In summary, the introduction of capillary tube 4 inserted into opening 3 in this embodiment not only enhances the flexibility and adjustability of the standard release container, but also provides users with a more convenient and efficient experimental operation experience. This innovative design will undoubtedly provide more accurate and reliable experimental data support for scientific research, industrial production, and quality control in related fields.

[0059] In a more sophisticated implementation of this embodiment, particular emphasis is placed on the sealed connection between the capillary tube 4 and the opening 3. The design of this sealed connection is crucial because it ensures that when the capillary tube 4 is inserted into the opening 3, the contact surface between the two can form a tightly sealed state, effectively preventing unintended leakage of gas or liquid.

[0060] To achieve an effective seal, various techniques may be employed. For example, a thin layer of sealant may be applied between the outer wall of the capillary tube 4 and the inner wall of the opening 3 to ensure a tight fit. Alternatively, a capillary tube 4 may be designed with a specially constructed sealant or elastic sealing element at its end, which automatically expands and fills any minor gaps when inserted into the opening 3.

[0061] The importance of a sealed connection lies not only in preventing leaks but also in precisely controlling the gas release rate. Because the gas release rate is affected by multiple factors, including pore diameter, pore depth, and the seal around the pore, ensuring a tight seal between the capillary tube 4 and the opening 3 is crucial for obtaining accurate and reliable gas release rate data.

[0062] Furthermore, the sealed connection improves the overall performance and stability of the standard release container. It reduces the impact of external environmental factors on the internal environment of the container, allowing gas release rate measurements to more closely resemble realistic, stable conditions. This is of great significance for scientific research, industrial production, and quality control.

[0063] In a more flexible and diverse implementation of this embodiment, multiple capillaries 4 are introduced, and the length of each capillary 4 is different. This design innovation provides more options and possibilities for adjusting the gas release rate.

[0064] By preparing multiple capillaries of varying lengths, users can select the appropriate length for insertion into opening 3 based on specific experimental or testing requirements. Because the depth of the opening is closely related to the gas release rate, capillaries of varying lengths correspond to different gas release rates. This design allows users to quickly and easily adjust the gas release rate to meet diverse experimental or testing requirements without having to replace the entire bottle cap or perform complex adjustments.

[0065] Furthermore, multiple capillary lengths offer users a wider range of adjustments. Whether fine-tuning the gas release rate for detailed studies or drastically changing it to simulate extreme conditions, users can achieve this by selecting the appropriate capillary. This flexibility significantly enhances the applicability and practicality of the standard release vessel.

[0066] In another embodiment of this invention, in order to flexibly meet the needs of changing the gas release rate, a completely different strategy than adding capillaries 3 is adopted: multiple bottle caps 2 with different opening depths are prepared. This design also provides users with a convenient way to adjust the gas release rate.

[0067] Specifically, since several bottle caps 2 are manufactured, the openings 3 on each cap are carefully designed to have different depths. These varying depths directly affect the rate of gas release after the standard liquid evaporates. Therefore, users can select a bottle cap with an appropriate opening depth to assemble the bottle body 1 based on the specific requirements of the experiment or test.

[0068] In this way, users do not need to make complex modifications or adjustments to individual bottle caps; they can simply replace the caps to change the gas release rate. This not only simplifies the operation process, but also reduces operational difficulty and error rate.

[0069] In addition, the availability of multiple caps with varying opening depths provides users with more options. Users can flexibly select or replace caps based on the different stages, conditions, or needs of an experiment or test, to meet diverse and complex experimental or testing requirements.

[0070] Although the terms "container," "bottle," and "bottle cap" are frequently used in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.

[0071] The utility model provides a standard release container. The bottle body is designed to contain a standard substance liquid and a bottle cap detachably connected thereto. An opening is provided on the bottle cap, so that the gas generated after the evaporation of the standard substance liquid can be constantly released. A standardized reference benchmark for gas release rate is scientifically and reasonably established, which can serve as the core comparison basis in the release chamber qualification test process, ensures the objectivity and fairness of the test results, and provides strong technical support and guarantee for scientific research, industrial production and quality control in related fields.

[0072] Example 2

[0073] The embodiment of the present utility model provides a gas release rate standard determination system, comprising a weighing device and a standard release container as provided in the above embodiment 1;

[0074] The weighing device is used to weigh the weight change of the standard release container to determine the gas release rate standard.

[0075] It should be noted that the working principle of the system is as follows:

[0076] Preparation stage:

[0077] A certain amount of standard substance liquid is injected into the bottle body of the standard release container.

[0078] If necessary, a suitable capillary tube can be selected and inserted into the opening of the bottle cap to adjust the gas release rate.

[0079] Place the assembled standard release container on the weighing device for initial weighing and record the initial weight.

[0080] Measurement phase:

[0081] The standard release container is placed under preset temperature, humidity and atmospheric pressure conditions to ensure the stability and repeatability of the measurement environment.

[0082] Start the weighing device and start real-time monitoring and recording the change in the container weight. As the standard liquid evaporates, the container weight will gradually decrease.

[0083] Record the container weight at preset time intervals (such as every minute, every hour, etc.) and calculate the weight change during this time period.

[0084] Data processing stage:

[0085] The gas release rate can be obtained by mathematical calculation using the collected weight change data.

[0086] It is understood that statistical parameters such as the average value and standard deviation of the gas release rate can be determined by performing statistical analysis on multiple measurement results to evaluate the stability and reliability of the measurement results.

[0087] In one implementation of this embodiment, the specific type of the weighing device is specified, that is, a balance is used as a tool to measure the weight change of the standard release container.

[0088] As a long-standing and widely used measuring tool, the balance features high precision, high stability, and ease of operation. In the gas release rate standard determination system, the balance can accurately monitor the weight change of the standard release container during the gas release process in real time, providing reliable basic data for subsequent data processing and gas release rate calculation.

[0089] Using a balance as a weighing device ensures accurate and repeatable measurement results. Balances typically achieve a high level of accuracy, meeting the demands for precise gas release rate measurements in scientific research and industrial production. Balances are also relatively simple to operate; users simply place a standard release container on the balance and weigh it to obtain the desired weight data.

[0090] Furthermore, balances have a wide range of applications, from small-scale laboratory research to large-scale industrial testing. This makes the gas release rate standard determination system more adaptable and flexible, meeting the needs of applications in different fields and at different scales.

[0091] In summary, the gas release rate standard determination system provided in Example 2 of the present invention provides strong technical support and guarantee for research and production in related fields with its high precision, flexibility and wide applicability.

[0092] Please refer to Figure 6 A method for determining a gas release rate standard based on a gas release rate standard determination system includes:

[0093] S101 , obtaining the initial weight of the standard release container before release and the final weight after release measured by a weighing device.

[0094] It should be noted that this step involves weighing the standard release container using a high-precision weighing device (such as a balance) and recording its initial weight before gas release. Then, after the predetermined release time, the container is weighed again, and the final weight after release is recorded.

[0095] It is understood that during the weighing process, the stability and accuracy of the weighing device should be ensured to avoid the influence of external factors (such as vibration, airflow, etc.) on the measurement results. At the same time, the accurate release time should be recorded for subsequent calculations.

[0096] S102. Calculate the gas release rate standard according to the following formula:

[0097] Gas release rate standard = (initial weight of standard release container before release − final weight after release) / release time.

[0098] It should be noted that during the calculation process, attention should be paid to the unification and conversion of units. For example, if the unit of release time is hours and the unit of weight is grams, the unit of the calculated gas release rate standard will be grams per hour. In addition, to improve the calculation accuracy, floating point numbers can be used for calculations, and an appropriate number of decimal places can be retained.

[0099] In summary, the method for determining a gas release rate standard provided in this embodiment can accurately determine the gas release rate standard through precise measurement and calculation. This method offers advantages such as ease of operation and reliable results, and can be widely applied in fields such as air quality monitoring, assessment of volatile organic compound emissions from building materials, and quality control of chemical products.

[0100] Please refer to Figure 7 , the embodiment of the utility model further provides a release chamber detection method, the method comprising:

[0101] S201. Place the release source into the release chamber.

[0102] It should be noted that this step involves placing the release source to be tested (such as building materials or chemical products containing volatile organic compounds) into the release chamber. The release chamber should be well sealed to ensure that the gas does not leak during the test process.

[0103] S202: Detecting the gas release rate of the release chamber at the detection port.

[0104] It should be noted that this step involves using appropriate testing equipment (such as a gas concentration sensor, flow meter, etc.) to detect the gas release rate in the release chamber. During the testing process, the accuracy and stability of the testing equipment should be ensured to obtain reliable data.

[0105] S203. Compare the gas release rate of the release chamber with the gas release rate standard to determine whether they are consistent; the gas release rate standard is determined by the gas release rate standard determination system provided in the above-mentioned embodiment 2; if so, execute step S204; if not, execute step S205.

[0106] It should be noted that this step is to compare the gas release rate detected in step S202 with the gas release rate standard determined by the gas release rate standard determination system provided in Example 2. When comparing, attention should be paid to the unification and conversion of units to ensure the accuracy of the comparison.

[0107] Judgment logic: If the gas release rate of the release chamber is consistent with the standard (completely consistent, or allowed within a preset error range), the release chamber is considered qualified and step S204 is executed; if not, the release chamber is considered unqualified and step S205 is executed.

[0108] S204: Determine whether the release bin is qualified.

[0109] It should be noted that when the gas release rate of the release chamber is consistent with the standard, the test result is recorded and the release chamber is determined to be qualified. This means that the release chamber has met the expected requirements in controlling the gas release rate.

[0110] S205: Determine whether the release bin is unqualified.

[0111] It should be noted that if the gas release rate of the release chamber does not meet the standard, the test results will be recorded and the release chamber will be determined to be unqualified. In this case, further analysis of the cause, such as the sealing of the release chamber and the nature of the release source, may be required to implement appropriate improvement measures.

[0112] In summary, the release chamber testing method provided in Example 4 achieves rapid and accurate assessment of release chamber eligibility by comparing the actual gas release rate from the release chamber with a preset gas release rate standard. This method offers advantages such as ease of operation and reliable results, and can be widely applied to release chamber testing in fields such as building materials and chemical products.

[0113] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
