[0027] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Reference Figures 1 to 5 As shown, the utility model provides a layered sampling device for food detection, comprising a base 1, a threaded sleeve 2, a sampling tube 3, and a separating insert 4.

[0030] In this embodiment, the base 1 is a rectangular support plate. The food to be tested is placed on the base. A pressing column is vertically arranged on the base 1. The height of the pressing column is adjustable. The pressing column is connected to a supporting arm 14.

[0031] Combination Figure 1 and Figure 2 As shown, the pressing column includes: a guide sleeve 11, a core rod 12, and a lifting spring 13.

[0032] The guide sleeve 11 is vertically arranged on the base 1. The core rod 12 is coaxially arranged with the guide sleeve. One end of the core rod 12 is movably inserted into the guide sleeve 11. The other end of the core rod 12 extends above the guide sleeve 11, and the other end of the core rod 12 is connected to one end of the support arm 14.

[0033] The lifting spring 13 is connected between one end of the core rod 12 and the bottom of the guide sleeve 11 .

[0034] In this embodiment, the lifting spring is a coil spring.

[0035] The threaded sleeve 2 is arranged vertically. The threaded sleeve 2 has an upper closed end and a lower open end. The upper closed end of the threaded sleeve 2 is connected to the support arm 14.

[0036] The sampling barrel 3 is used to accommodate soft and glutinous food samples. The sampling barrel adopts a spliced ​​barrel body. Specifically, the sampling barrel 3 includes two arc-shaped plates 31. The two arc-shaped plates 31 are detachably enclosed to form the sampling barrel 3. One arc-shaped plate 31 is provided with a plurality of insert openings 30. The plurality of insert openings 30 are arranged at intervals in the vertical direction. An external thread is formed at one end of the sampling barrel 3. One end of the sampling barrel 3 is screwed into the lower open end of the threaded sleeve 2.

[0037] See also Figure 1 , and combined with Figure 4 and Figure 5As shown, Figure 4 and Figure 5 The schematic diagram of the cross section of the insert opening of the sampling tube is shown. In this embodiment, the arc plate is semicircular. The arc plate has two opposite sides in the arc direction. The opposite sides of one arc plate are provided with socket grooves. The opposite sides of the other arc plate are formed with plug-in convex ridges. The plug-in convex ridges of the other arc plate are detachably inserted into the socket grooves of one arc plate so that the two arc plates are enclosed to form the sampling tube.

[0038] In this embodiment, a limiting flange 311 is formed on one side of the plug-in convex ridge away from the other arc-shaped plate. An anti-slip flange for preventing the limiting flange from slipping is formed on the opposite extension of the notch of the socket through groove. The anti-slip flange abuts against the inner side of the limiting flange.

[0039] Furthermore, the cross-sections of the plug-in ribs and the limiting flanges are T-shaped, and the cross-sectional shape and size of the socket through grooves are adapted to the cross-sectional shapes and sizes of the plug-in ribs and the limiting flanges.

[0040] There are multiple partition inserts 4. The partition inserts 4 are inserted into the soft and glutinous food sample in the sampling tube 3 through the insert opening 30 to intercept the target layer of the soft and glutinous food.

[0041] The insertion position of the separation insert is based on the position of the target layer of the soft and glutinous food. In this embodiment, the soft and glutinous food is pastry, cake, etc.

[0042] In this embodiment, the length of the insert opening 30 is smaller than the diameter of the sampling tube 3. The length of the partition insert 4 is adapted to the diameter of the sampling tube 3. The width of the partition insert 4 is smaller than the length of the insert opening 30. The diameter of the sampling tube 3 described in this embodiment is the inner diameter of the sampling tube 3.

[0043] See also Figure 5 As shown, the separating insert 4 is oval in shape.

[0044] As a preferred embodiment, the other end of the support arm 14 is connected with a vertical rod 141. The vertical rod 141 is connected to the upper closed end of the threaded sleeve 2.

[0045] In this embodiment, the upper closed end is provided with an air hole, which is connected to a suction air pipe 21. The suction air pipe is used to exhaust the air in the sampling tube and can also assist in adsorbing the soft and glutinous food sample in the sampling tube to prevent the sampling tube from slipping out.

[0046] When sampling, the soft and glutinous food to be tested is placed on the base and placed below the sampling tube. The tester presses the support arm toward the base so that the sampling tube is inserted into the soft and glutinous food. When the soft and glutinous food enters the lower port of the sampling tube, the suction air pipe draws out the gas in the sampling tube so that the soft and glutinous food enters the sampling tube smoothly. The suction air pipe can be connected to a small suction pump.

[0047] After the sampling tube is inserted into the bottom of the soft and glutinous food, the inspector slowly releases the supporting arm, so that the core rod is pushed by the elasticity of the lifting spring, and the sampling tube carrying the soft and glutinous food sample retreats to the top of the soft and glutinous food on the base.

[0048] When the sampling tube slowly withdraws the soft and glutinous food, based on the position of the target layer of the soft and glutinous food, one end of the separating insert is inserted into the soft and glutinous food sample in the sampling tube through the insert opening, and the other end of the separating insert is inserted in the insert opening, thereby preventing the soft and glutinous food from slipping out of the sampling tube.

[0049] In addition, when the height of the sampling tube is adapted to the thickness of the soft and glutinous food, before the sampling tube is inserted into the soft and glutinous food, a smooth gasket is placed at the sampling position of the soft and glutinous food, so that the bottom of the smooth gasket fits tightly against the upper surface of the soft and glutinous food. The smooth gasket is circular and its size is slightly smaller than the inner diameter of the sampling tube. When the sampling tube is inserted into the soft and glutinous food, it is just accommodated in the sampling tube together with the smooth gasket. After the suction pipe continues to evacuate air, when the top of the smooth gasket fits against the inner wall of the upper closed end of the threaded sleeve, the soft and glutinous food sample is stably adsorbed in the sampling tube.

[0050] When the sampling tube is completely removed from the soft and glutinous food on the base, the sampling tube is rotated to remove the sampling tube from the threaded sleeve, and then the other ends of all the partition inserts are inserted into the soft and glutinous food sample, that is, the partition inserts are completely inserted into the sampling tube.

[0051] The two curved plates of the sampling tube are separated and staggered so that the soft and glutinous food sample is left on one curved plate, and the inspector can take out the target layer of the soft and glutinous food between the two separation inserts, thereby realizing layered sampling. In this embodiment, a scale line is set on the outer side of one curved plate of the sampling tube. With the help of the scale line, when intercepting the target layer, the inspector can accurately insert the separation insert into the corresponding insert opening.

[0052] After the sampling is completed, the two curved plates have smooth inner walls and can be disassembled, so the cleaning of the two curved plates is very convenient and quick.

[0053] The layered sampling device for food testing of the utility model adopts a spliced ​​sampling tube, which is very convenient and quick to clean after sampling. In addition, the target layer of the soft and glutinous food sample can be intercepted with the help of the partition insert, which can not only accurately obtain the sample of the target layer, but also prevent the target layer of the soft and glutinous food from slipping out of the sampling tube, thereby improving the one-time success rate of sampling.

[0054] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical solution.
