AI Technical Summary
Existing technologies typically require opening the cigarette box and relying on smell and observation to determine if cigarettes are moldy, which results in cigarette loss and is not accurate enough.
The mold inside the cigarette is drawn into the culture medium in a vacuum petri dish by using vacuum negative pressure. The mold growth is then determined by observing the colonies in the petri dish, thus avoiding cigarette loss.
It enables non-destructive testing of cigarette mold, improving testing accuracy and efficiency while avoiding destructive loss of cigarettes.

Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the field of cigarette technology, and more particularly, to a mold detection device for cigarettes. BACKGROUND
[0002] During the circulation and storage of cigarettes, mold may grow on the tobacco due to high temperature and high humidity, causing the cigarettes to mold. Moldy cigarettes lose their original color, aroma and taste, and bring bad smoking experience to consumers.
[0003] The commonly used method for identifying mold of cigarettes is to open the transparent cover of the cigarette box, take out the cigarettes, and determine whether there is a moldy smell by smell, whether there are white mycelium on the tobacco, and whether there are mold spots such as green, blue and black on the appearance of the cigarettes. This method is destructive and causes unnecessary loss. CONTENT OF THE UTILITY MODEL
[0004] The present application provides a mold detection device for cigarettes, which can drain the mold in the cigarettes into the culture solution in the vacuum culture dish through the vacuum negative pressure effect, and determine whether the cigarettes have mold by observing whether there are colonies in the culture dish after culture, thereby avoiding the loss caused by destroying the cigarettes.
[0005] The present application provides a mold detection device for cigarettes, which includes a vacuum culture dish and a drainage part arranged on the top surface of the vacuum culture dish.
[0006] At least one side surface of the vacuum culture dish is transparent, the top surface of the vacuum culture dish is provided with a drainage hole, and the drainage part is provided with a drainage assembly at a position corresponding to the drainage hole.
[0007] During the detection process, the end of the detected cigarette abuts against the drainage assembly.
[0008] Preferably, the drainage assembly includes a sterilized latex tube extending upward from the drainage hole to the top surface of the drainage part, and a switch arranged on the sterilized latex tube.
[0009] Preferably, the switch includes a plug-in switch arranged on the outer side of the drainage part, and a pull wire extending from the plug-in switch through the side wall of the drainage part to the sterilized latex tube, the pull wire surrounds and tightens the sterilized latex tube and forms a running knot.
[0010] Preferably, the sterilized latex tube is provided with a one-way valve.
[0011] Preferably, the upper side of the drainage part is further provided with a cigarette box accommodating cavity, the size of the cigarette box accommodating cavity matches the size of the finished cigarette box, and the bottom surface of the cigarette box accommodating cavity is provided with an air outlet hole at a position corresponding to the sterilized latex tube.
[0012] Preferably, the pull wire is a fiber rope.
[0013] Other features and advantages of this application will become clear from the following detailed description of exemplary embodiments with reference to the accompanying drawings. Attached Figure Description

[0018] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps set forth in these embodiments do not limit the scope of the present application.
[0019] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.
[0020] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.
[0021] In all the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.
[0022] This application provides a cigarette mold detection device, which uses vacuum negative pressure to guide the mold inside the cigarette into the culture medium in a vacuum petri dish. After culturing in the petri dish, the presence of bacterial colonies is observed to determine whether the cigarette has become moldy, thus avoiding losses caused by damaging the cigarette.
[0023] As an example, such as Figure 1 and 2 As shown, the cigarette mold detection device provided in this application includes a vacuum culture dish 20 and a drainage part 30 disposed on the top surface of the vacuum culture dish 20.
[0024] The vacuum culture dish 20 contains a culture medium for cultivating mold. At least one side of the vacuum culture dish 20 is transparent, forming a transparent window for easy observation of changes in the culture medium. A drainage hole is provided on the top surface of the vacuum culture dish 20, and a drainage component 31 is provided on the drainage part 30 at a position corresponding to the drainage hole. During the testing process, the end of the cigarette being tested comes into contact with the drainage component 31.
[0025] As an example, such as Figure 3 As shown, the drainage assembly 31 includes a sterilized latex tube 311 extending upward from the drainage hole to the top surface of the drainage section 30, and a switch disposed on the sterilized latex tube 311.
[0026] As one embodiment, the switch includes a plug-in switch 313 disposed outside the drainage section 30 and a pull wire 312 extending through the side wall of the drainage section 30 to the sterilized latex tube 311. The pull wire 312 surrounds and tightens the sterilized latex tube 311 to form a slip knot.
[0027] As an example, the pull cord 312 is a fiber rope to ensure that the pull cord 312 will not be broken during use.
[0028] Preferably, the sterilized latex tube 311 is provided with a one-way valve 314 to prevent the airflow in the vacuum culture dish from flowing back into the cigarette and causing the cigarette to become contaminated.
[0029] Based on the above, preferably, a cigarette box receiving cavity 10 is also provided above the flow-in portion 30. The size of the cigarette box receiving cavity 10 matches the size of the finished cigarette box, and an air outlet is provided on the bottom surface of the cigarette box receiving cavity 10 at a position corresponding to the sterilization latex tube 311. The cigarette box receiving cavity allows almost all the mold-containing gas in the cigarette to enter the vacuum culture dish, improving the accuracy of detection.
[0030] When consumers or merchants receive the boxed cigarettes, they open one end of the box and insert the cigarettes into the cigarette box's receiving cavity, with the opening facing the inlet assembly. Pulling outwards from the plug switch opens the slipknot attached to the latex tube, connecting the vacuum culture dish to the cigarettes inside the cigarette box's receiving cavity. Because the vacuum culture dish is under vacuum, a pressure difference is created between it and the air inside the cigarette box's receiving cavity, causing airflow from the receiving cavity to flow through the sterilized latex tube into the culture medium within the vacuum culture dish. After culture in the dish, if the cigarettes become moldy, the air inside the cigarette box's receiving cavity will contain mold. The mold will enter the vacuum culture dish and begin to multiply. Within one to two days, colonies will appear in the culture dish, which can be observed through the transparent window, thus determining if the cigarettes inside the box have become moldy. If the cigarettes are not moldy, no colonies will form in the culture dish.
[0031] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
