By testing the total amount of volatile components in tobacco flavorings, we can ensure that the total amount of volatile components remains consistent across each batch, thereby guaranteeing the stability and consistency of cigarette product quality.

[0003] In existing technologies, water baths are commonly used to determine the total volatile components of tobacco flavorings and fragrances. Water baths are typically placed directly in the natural environment, and the pressure used for testing is the local atmospheric pressure. However, due to differences in altitude, atmospheric pressure varies across regions, which affects the water bath's results for determining the total volatile components of tobacco flavorings and fragrances. Therefore, the consistency of test results across different regions is poor, making comparative analysis of the results difficult.

[0004] Therefore, there is an urgent need for a device for measuring the total amount of volatile components in tobacco flavorings and fragrances to solve the above-mentioned technical problems. Utility Model Content

[0035] like Figure 1As shown, this embodiment provides a device for determining the total volatile components of tobacco flavorings, including a water bath 1, an evaporating dish 2, a sealing cover 3, and a pressure regulating component 4. The sample to be tested is placed inside the water bath 1, and a placement position 11 is provided on the water bath 1, where the evaporating dish 2 is placed. A sealed space is formed inside the sealing cover 3, and the evaporating dish 2 is placed within the sealed space. The sealed space is connected to the interior of the water bath 1, meaning the pressure in the sealed space is the same as inside the water bath 1. The pressure regulating component 4 includes a barometer 41 and a constant pressure valve 42. Part of the barometer 41 is located outside the sealing cover 3, and the other part extends into the sealing cover 3 to detect the pressure inside the sealing cover 3. The constant pressure valve 42 is installed on the sealing cover 3 and can adjust the pressure inside the sealing cover 3. To ensure that the pressure inside the water bath 1 is the same, before testing, the constant pressure valve 42 is adjusted, and the pressure value displayed by the barometer 41 is observed to adjust the pressure inside the sealing cover 3 to standard atmospheric pressure before testing. By adjusting the pressure inside the sealing cover 3 to standard atmospheric pressure, the pressure inside the water bath 1 is uniformly at standard atmospheric pressure. This ensures that the water bath 1 in different regions is tested under the same pressure, improving the consistency of the test results. Furthermore, this device for determining the total volatile components of tobacco flavorings and fragrances has a simple structure and is easy to operate.

[0036] Specifically, the water bath 1 has a rectangular parallelepiped structure. The sample to be tested is tobacco flavoring. The sealing cover 3 has a rectangular parallelepiped structure, and the sealed space is a rectangular parallelepiped space with a length greater than or equal to 75 cm, a width greater than or equal to 60 cm, and a height greater than or equal to 70 cm. The wall thickness of the sealing cover 3 is greater than or equal to 0.5 cm, giving the sealing cover 3 a certain strength. The barometer 41 and the constant pressure valve 42 are both installed on the top of the sealing cover 3. The barometer 41 includes a detection part and a display part. The display part is located outside the sealing cover 3, and the detection part extends into the sealing cover 3. The range of the barometer 41 is 80-106 kPa. The specific structure of the barometer 41 is based on the prior art and will not be described in detail here.

[0037] Optionally, multiple placement positions 11 are provided, with each evaporating dish 2 corresponding to one of the placement positions 11. Providing multiple placement positions 11 allows multiple evaporating dishes 2 to be placed on the water bath 1, thereby shortening the detection time and improving detection efficiency. The specific number of placement positions 11 is determined according to the size of the water bath 1, and this embodiment does not limit this.

[0038] Optionally, the sealing cover 3 is made of a transparent material to facilitate observation of the internal environment of the sealing cover 3.

[0039] Optionally, the sealing cover 3 is placed on one side of the water bath 1 at the placement position 11, and the sealing cover 3 is sealed to the water bath 1, so that the water bath 1 is located outside the sealing cover 3, which facilitates the connection of the water bath 1 to the power supply.

[0040] In other embodiments, the water bath 1 can be placed within a sealed space, with a through hole in the sealing cover 3. A sealing plug is installed at the through hole, and an electrical wire is connected to the water bath 1. One end of the wire passes through and extends out of the through hole 12 to connect to an external power source, ensuring the sealing of the sealing cover 3. The diameter of the through hole 12 is greater than or equal to 2.5 cm. The annular seal is made of rubber.

[0041] Optionally, the sealing cover 3 includes a box body 31 and a box door 32. The box body 31 is provided with an opening, and one side of the box door 32 is rotatably connected to the box body 31. The box door 32 can block the opening. By providing the box door 32, it is convenient to place the evaporating dish 2 into the sealing cover 3 and to take out the evaporating dish 2. The box door 32 is rotatably connected to the box body 31, which facilitates the opening and closing of the box door 32.

[0042] Specifically, the opening is located on the side wall of the box body 31, and the box door 32 is rotatably connected to the side wall of the opening via hinges. Two hinges are spaced apart vertically to improve the stability of the connection between the box door 32 and the box body 31. The box door 32 has a rectangular plate-like structure. The length of the box door 32 is greater than or equal to 75cm, the width is greater than or equal to 60cm, the height is less than or equal to 15cm, and the thickness is greater than or equal to 0.5cm.

[0043] Optionally, the device for measuring the total volatile components of tobacco flavorings and fragrances also includes a door lock assembly 5. The door lock assembly 5 includes a first lock body 51 and a second lock body 52. ​​One of the first lock body 51 and the second lock body 52 is connected to the housing 31, and the other is connected to the door 32. The first lock body 51 and the second lock body 52 are fixedly connected. The door lock assembly 5 can fix the door 32 to the housing 31, preventing the door 32 from rotating after it is closed.

[0044] Specifically, the first lock body 51 is fixed to the side of the door 32 away from the hinge by screws, and the second lock body 52 is installed on the side wall of the door 31 by screws, corresponding to the first lock body 51. The first lock body 51 can be locked in place by engaging with the second lock body 52. ​​In other embodiments, the first lock body 51 and the second lock body 52 can also be connected by magnetic attraction or by thread.

[0045] Optionally, the device for determining the total volatile components of tobacco flavorings and fragrances also includes a temperature measuring component 6, which can measure the temperature of the sample to be tested in the water bath 1, thereby obtaining the temperature of the sample to be tested in the water bath 1, i.e., the tobacco flavorings and fragrances, so as to analyze the total volatile components of the tobacco flavorings and fragrances.

[0046] Specifically, the temperature measuring component 6 includes a temperature measuring element and a display screen. The temperature measuring element is set inside the water bath 1, and the display screen is installed on the outer wall of the water bath 1. The temperature measuring element and the display screen are connected in communication so that the temperature measured by the temperature measuring element is displayed on the display screen for easy observation.

[0047] Optionally, the pressure regulating assembly 4 also includes a control element. The control element is communicatively connected to the barometer 41 and the constant pressure valve 42. The barometer 41 transmits the measured pressure value to the control element. If the pressure value differs from atmospheric pressure, the control element controls the constant pressure valve 42 to adjust the pressure inside the sealing cover 3 until the pressure value of the barometer 41 equals atmospheric pressure. The constant pressure valve 42 is automatically adjusted by the control element, which is convenient and provides higher accuracy. The constant pressure valve 42 is an automatically controlled constant pressure valve. Specific control elements are described in the prior art and will not be elaborated upon here.

[0048] Optionally, the device for determining the total volatile components of tobacco flavorings and fragrances also includes a one-way permeable membrane. This membrane covers the evaporating dish 2, allowing gas within the dish to pass through it, thus evaporating the volatile components. Since the volatile components produce vapor after evaporation, the one-way permeable membrane prevents this vapor from falling into the evaporating dish 2 under gravity, ensuring the accuracy of the measurement results.

[0049] In another embodiment, the device for determining the total volatile components of tobacco flavorings and fragrances further includes a one-way vent valve. The one-way vent valve is installed on the evaporating dish 2, allowing gas inside the evaporating dish 2 to pass through it. This prevents the vapor generated after the volatile components of the tobacco flavorings and fragrances evaporate from the dish and from falling back into the evaporating dish 2 under gravity, ensuring the accuracy of the measurement results. Specifically, a cover plate is provided on top of the evaporating dish 2, and the cover plate has vent holes. The one-way vent valve is installed on the cover plate and seals the vent holes, allowing gas inside the evaporating dish 2 to pass through the one-way vent valve.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
