[0002] Accurate flour sampling is crucial in flour production, processing, and quality testing. However, while existing flour sampling devices improve sampling convenience to some extent, they also present several problems. For example, some samplers have poorly designed structures, resulting in significant resistance when inserting into the flour. This not only makes operation laborious but may also damage the original structure of the flour, affecting its quality. Furthermore, these sampling devices can easily cause flour to fly around during sampling, polluting the working environment and harming the health of operators. In addition, existing sampling devices present difficulties in sample preservation and transportation after sampling. Many devices lack adequate sealing measures, making flour leakage during transportation easy, leading to sample loss and potentially contaminating the surrounding environment. Moreover, the lack of effective sealing can allow external air and moisture to enter the sample, affecting flour quality and test results.

[0003] In summary, there is an urgent need for a flour sampling device that is easy to operate, accurate in sampling, can effectively prevent flour from flying and contaminating, and is convenient for sample preservation and transportation, so as to meet the actual needs of flour production and quality testing.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1

[0026] like Figure 1-2 As shown, a flour sampling device includes a sample insertion tube 1, a sealing head 4 inserted into the bottom of the sample insertion tube 1, a handheld rod 15 connected to the top of the sample insertion tube 1, a power supply fixing shell 14 connected to the top of the handheld rod 15, a control switch 12 connected to the top of the power supply fixing shell 14, a sampling tube 6 inserted inside the sample insertion tube 1, a sample inlet groove 7 opened on the side of the sampling tube 6, a lower sealing block 5 connected to the bottom of the sampling tube 6, an upper sealing block 8 connected to the top of the sampling tube 6, a miniature electric push rod 10 connected inside the handheld rod 15, a connector 9 connected to the pushing end of the miniature electric push rod 10, the connector 9 passing through the sample insertion tube 1 and detachably connected to the upper sealing block 8, a mobile power supply 11 connected inside the power supply fixing shell 14, and the miniature electric push rod 10 connected to the mobile power supply 11 through the control switch 12.

[0027] Working principle

[0028] 1. Preparation

[0029] Before sampling the flour, first check that all parts of the sampling device are intact. Ensure that the sampling tube 1 and sampling tube 6 are clean and free of impurities, ensure that the power supply 11 has sufficient power, and ensure that the mini electric push rod 10, the power supply 11, and the control switch 12 can be connected and work normally.

[0030] 2. Insertion sampling

[0031] Pull out the sealing head 4, align the sample tube 1 with the flour pile or flour bag, and gently insert the sample tube 1 into the flour.

[0032] 3. Start sampling

[0033] Once the sample tube 1 is inserted to the appropriate depth, press the push button on the control switch 12. The micro electric push rod 10 starts to push, and the micro electric push rod 10 pushes the upper sealing block 8 through the connector 9. The upper sealing block 8 pushes the sampling tube 6 out of the sample tube 1, and the flour outside enters the sampling tube 6 through the sample inlet groove 7.

[0034] 4. Sampling completed

[0035] After sampling is completed by the sampling tube 6, press the retraction button of the control switch 12. The miniature electric push rod 10 starts the retraction operation. The miniature electric push rod 10 pulls the upper sealing block 8 through the connector 9. The upper sealing block 8 pulls the sampling tube 6 to re-insert it into the sampling tube 1.

[0036] The lower sealing block 5 and the upper sealing block 8 seal the sampled flour within the space between the sampling tube 1 and the sampling tube 6, while the sealing head 4 is reconnected to prevent the sampling tube 6 from shifting downwards. Replacing the sampling tube 1 with a new one connected to the sampling tube 6 allows for the next sampling operation.

[0037] Example 2

[0038] like Figure 1-2 As shown, a flour sampling device includes a sample insertion tube 1, a sealing head 4 inserted into the bottom of the sample insertion tube 1, a handheld rod 15 connected to the top of the sample insertion tube 1, a power supply fixing shell 14 connected to the top of the handheld rod 15, a control switch 12 connected to the top of the power supply fixing shell 14, a sampling tube 6 inserted inside the sample insertion tube 1, a sample inlet groove 7 opened on the side of the sampling tube 6, a lower sealing block 5 connected to the bottom of the sampling tube 6, an upper sealing block 8 connected to the top of the sampling tube 6, a miniature electric push rod 10 connected inside the handheld rod 15, a connector 9 connected to the pushing end of the miniature electric push rod 10, the connector 9 passing through the sample insertion tube 1 and detachably connected to the upper sealing block 8, a mobile power supply 11 connected inside the power supply fixing shell 14, and the miniature electric push rod 10 connected to the mobile power supply 11 through the control switch 12.

[0039] The bottom of the sample insertion tube 1 is tapered. This design facilitates the insertion of the sample insertion tube 1 and effectively improves its working efficiency and effectiveness.

[0040] The sample tube 1 is embedded with a viewing window 2 corresponding to the sample inlet groove 7. The viewing window 2 allows the user to easily observe the sample volume of the sampling tube 6, which can effectively improve the working efficiency and effect of the sampling tube 6.

[0041] The sample insertion tube 1 is made of stainless steel. Stainless steel products have good hardness, as well as good wear resistance and corrosion resistance, resulting in a long service life for the stainless steel sample insertion tube 1.

[0042] A pull ring 3 is connected to the bottom of the sealing head 4. This design makes it easy for the user to pull the sealing head 4, which can effectively improve the working efficiency and performance of the sealing head 4.

[0045] The sealing head 4, lower sealing block 5, and upper sealing block 8 are all made of rubber. Rubber products have good compressibility, as well as good wear resistance and corrosion resistance, resulting in a long service life for the sealing head 4, lower sealing block 5, and upper sealing block 8 made of rubber.

[0046] The upper sealing block 8 is threadedly connected to the connector 9. This design facilitates the connection between the upper sealing block 8 and the connector 9, effectively improving the connection efficiency between them.

[0047] The power bank 11 uses a rechargeable lithium battery. Rechargeable lithium batteries can be repeatedly charged and used, effectively reducing the operating cost of the power bank 11.

[0048] A glove strap 13 is attached to the outside of the power supply housing 14. This design makes it easier for the user to carry the handheld lever 15, effectively improving the working efficiency and performance of the handheld lever 15.
