Description

Technical Field

[0001] The present application relates to the technical field of tobacco flavor testing, and in particular to a sampler capable of accurately sampling at different depths in a tobacco flavor blending tank. Background Art

[0002] Tobacco flavors are indispensable additives in the modern cigarette industry, as they impart aroma characteristics to tobacco products, blend the aroma of tobacco, improve the quality of smoking, and improve processing performance. In the production process of tobacco flavors, different tobacco flavors and solvents are first accurately added to the tobacco flavor mixing tank according to the formula ratio, and then stirred and mixed. After the mixture is evenly mixed, it can be filled. The formula ratio of some flavors in tobacco flavors may be one hundred thousandth or even one millionth of the dosage (mass fraction), so the formula ratio of each flavor and solvent is required to be very accurate when adding the materials. At the same time, it is also required that the quality and component uniformity of the obtained flavors after even mixing in the production process are good.

[0003] Since the properties of different tobacco flavors vary greatly, from the perspective of morphology, there are solid and liquid flavors, as well as viscous extract-like flavors, uniform solution-type flavors, and suspension-type flavors; from the perspective of color, there are colorless and transparent flavors, as well as light yellow, light brown flavors, and dark brown flavors; from the perspective of physical and chemical properties, there are hydrophilic flavors and hydrophobic flavors. Therefore, whether the flavor is evenly mixed during the blending process is very important, and it is necessary to sample and test samples at different locations in the blending tank before making a judgment. However, the tobacco flavor blending tank is generally large in volume, with a volume of about 1000 liters to 20000 liters. In the prior art, non-sealed samplers are generally used for sampling samples of different depths in the blending tank. After the sampler reaches the preset depth, it pauses, and then the sampler is removed from the liquid surface to complete the sampling. When the non-sealed sampler enters the liquid surface, the liquid starts to automatically enter the sampler until it is full. The sample taken is difficult to accurately represent the sample condition at the predetermined sampling depth. Moreover, the deeper the sampling site, the worse the sampling representativeness. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a sampler which can accurately take samples at different depths in a tobacco flavor blending tank. The sampler only takes samples at a predetermined depth, and the samples taken are highly representative.

[0005] The technical solution provided by the utility model is as follows:

[0006] A sampler that can accurately sample at different depths in a tobacco flavor blending tank, comprising a sampling container, a ventilation port provided at the upper end of the sampling container, and a sampling port provided at the lower end of the sampling container. A sealing unit is provided at the sampling port for opening the sampling port during sampling and being in a sealed state before sampling. A one-way check valve is provided at the connection between the sampling container and the sampling port. A floating ball is provided in the sampling container, and the outer diameter of the floating ball is larger than the inner diameter of the ventilation port.

[0007] Preferably, the sealing unit includes a sealing sleeve provided at the end of the sampling port and a control switch for controlling the opening of the sealing sleeve. The inner diameter of the sealing sleeve matches the outer diameter of the sampling port.

[0008] Preferably, the control switch includes a pressing rod and a fixing bracket for fixing the pressing rod. One end of the pressing rod is fixedly connected to the sealing sleeve.

[0009] Preferably, a plurality of ventilation pipe assemblies matching the ventilation port are connected to the ventilation port. The plurality of ventilation pipe assemblies are assembled in the same direction to form a long pipe matching the sampling depth. The height of the operating end of the pressing rod is not less than the height of the ventilation end of the long pipe.

[0010] Preferably, the ventilation pipe assemblies are also fixed by the fixing bracket.

[0011] Preferably, the fixing bracket includes a plurality of clamping sleeves.

[0012] Preferably, a scale mark one is provided on the outer surface of the ventilation pipe assembly, and the scale mark one is arranged along the length direction of the ventilation pipe assembly.

[0013] Preferably, the pressing rod is formed by connecting several sections of rods by means of connectors or by threaded connection.

[0014] Preferably, a scale mark two is provided on the sampling container, and the scale mark two starts from the top end of the sampling port and ends at the top end of the ventilation port.

[0015] Preferably, the end of the sampling container at the part connected to the ventilation port has a conical structure, and the diameter gradually becomes smaller from the sampling container to the ventilation port direction.

[0016] The present application has the following advantages compared with the prior art:

[0017] By using the sampler of the present application, before the sampler reaches the predetermined depth, the sampler is in a closed state; when the sampler reaches the predetermined depth, the sampling port opens for sampling; after sampling is completed, the sampler is in a closed state again. Therefore, the sampler only samples at the predetermined depth, and the representativeness of the samples taken is strong, and accurate sampling can be carried out at different depths in the tobacco flavor blending tank.

[0023] In order to enable those skilled in the art to better understand the technical solutions in the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of them. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present application.

[0024] Embodiment 1:

[0025] As Figure 1 shown, the embodiment of the present utility model provides a sampler that can accurately sample at different depths in a tobacco flavor blending tank, including a sampling container 1, a ventilation port 11 provided at the upper end of the sampling container 1, and a sampling inlet 12 provided at the lower end of the sampling container 1. A sealing unit 2 for opening the sampling inlet 2 during sampling and being in a sealed state before sampling is provided at the sampling inlet 12. A one-way check valve 3 is provided at the connection between the sampling container 1 and the sampling inlet 12. The liquid flow direction is from the sampling inlet 12 into the sampling container 1. Each time sampling is performed, a sampling container 1 with a suitable volume is selected according to the volume of the sample. A floating ball 4 is provided in the sampling container 1. The outer diameter of the floating ball 4 is greater than the inner diameter of the ventilation port 11. By using the floating ball 4 in the sampling container 1, the volume of each sample can be kept consistent, which is beneficial for batch sampling.

[0026] In this embodiment, the sealing unit 2 includes a sealing sleeve 21 disposed at the end of the injection port 12 and a control switch 22 for controlling the opening of the sealing sleeve 21. The inner diameter of the sealing sleeve 21 matches the outer diameter of the injection port 12. The control switch 22 includes a pressing rod 221 and a fixing frame 222 for fixing the pressing rod 221. One end of the pressing rod 221 is fixedly connected to the sealing sleeve 21. The fixing frame 222 includes a plurality of jackets.

[0027] In this embodiment, a second scale mark (not shown in the figure) is provided on the sampling container 1. The second scale mark starts from the top of the injection port 12 and ends at the top of the vent 11. The second scale mark can indicate the depth of the sampling container 1 entering the liquid surface.

[0028] In this embodiment, the end of the sampling container 1 at the portion where the sampling container 1 is connected to the vent 11 is in a tapered structure, and the diameter gradually decreases from the sampling container 1 to the vent 11 .

[0029] The sampling process of the sampler of this embodiment that can accurately sample at different depths in the tobacco flavor blending tank is as follows:

[0030] From the top of the mixing tank, insert the sampler from top to bottom into the essence liquid surface of the mixing tank. According to the second scale mark on the sampling container 1, when the position of the bottom of the sampler (i.e., the sealing sleeve 21) reaches the predetermined sampling depth, press the pressing rod 221 downward. At this time, the sealing sleeve 21 is separated from the sampling port 12, and the essence sample enters the sampling container from the sampling port 12; as more and more essence is in the sampling container 1, the liquid level rises, and the float 4 continues to rise with the liquid level. Finally, when the float 4 presses against the vent 11, the essence no longer enters the sampling container 1. Since a one-way check valve 3 is provided at the connection between the sampling container 1 and the sampling port 12, the sampler is taken out upward at this time, and the connection between the sampling container 1 and the sampling port 12 is in a sealed state.

[0031] Embodiment 2:

[0032] like Figure 2As shown, the difference between this embodiment and Embodiment 1 is that: to adapt to sampling of samples at different depths, a number of ventilation pipe assemblies 5 matching the ventilation port 11 are connected to the ventilation port 11. During sampling, according to the different sampling depths, it is determined whether the ventilation pipe assemblies 5 need to be connected and how many ventilation pipe assemblies 5 are needed, and they are connected. The number of ventilation pipe assemblies 5 are assembled in the same direction to form a long pipe matching the sampling depth. The height of the operating end of the pressing rod 221 is not less than the height of the ventilation end of the long pipe. The material, inner diameter, and outer diameter of the ventilation pipe assembly 5 are the same as those of the ventilation port. The ventilation pipe assembly 5 can be conveniently and fixedly connected to the ventilation port 11, and has good sealing performance; convenient and fixed connection can also be achieved between the internal pipes of the ventilation pipe assembly 5, and the sealing performance is good. A first scale mark (not shown in the figure) is provided on the outer surface of the ventilation pipe assembly 5, and the first scale mark is arranged along the length direction of the ventilation pipe assembly 5. The ventilation pipe assembly 5 is also fixed by a fixing frame 222 (jacket). The pressing rod 221 is formed by connecting several sections of rods by means of connectors or threaded connections, and convenient and fixed connection can be achieved. The rest is the same as in Embodiment 1.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
