[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model provides a sampling device for food safety detection, such as Figure 1-4 As shown, the sampling device for food safety detection includes: a sampling head 1, on which a storage shell 2 for storing food samples is fixedly mounted, handles are fixedly mounted on both sides of the storage shell 2, a discharge pipe is fixedly mounted on the storage shell 2, and a sealing cover is threadedly mounted on the discharge pipe; a motor 3 is fixedly mounted on the inner wall of the top of the storage shell 2, a rotating shaft 4 is fixedly mounted on the output shaft of the motor 3, and the rotating shaft 4 is located inside the sampling head 1; a spiral blade 5 is fixedly mounted on the rotating shaft 4; a cavity 6 for storing water is opened on the storage shell 2, and an installation port is opened on the inner wall of one side of the cavity 6; a shielding mechanism mounted on the storage shell 2 for shielding air; a cooling mechanism mounted on the storage shell 2 for storing samples at low temperatures.

[0023] In this embodiment, when sampling food, a person holds the handle and inserts the sampling head 1 of the device into the food, then starts the motor 3, the motor 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the spiral blade 5 to rotate, so that the food sample entering the sampling head 1 can be pushed into the storage shell 2. After the sampling is completed, the sampling head 1 is pulled out of the food, and then the shielding mechanism is used to block the air in the sampling head 1, and the air is blocked from entering the storage shell 2, which can reduce the contact between the sample and the external environment and reduce the risk of sample deterioration. Then, the cooling mechanism is started to cool the water in the cavity 6. Through the cooling effect of the water, the food sample in the storage shell 2 can be cooled, and then the food sample in the storage shell 2 can be stored at low temperature, so that the sample will not deteriorate during transportation, which can improve the accuracy and reliability of subsequent laboratory analysis, and the preservation effect is better. When it is necessary to take out the sample, the sealing cover is opened, and then the food sample stored in the storage shell 2 can be poured out from the discharge pipe by tilting the device.

[0024] In a further preferred embodiment of the utility model, the shielding mechanism includes: a sliding rod 7 fixedly mounted on the inner wall of the bottom of the storage shell 2, and a sliding block 8 is slidably mounted on the sliding rod 7; a sleeve 9 slidably sleeved on the sampling head 1, and one side of the sleeve 9 is fixedly connected to one side of the sliding block 8; a screw rod 10 rotatably mounted on the storage shell 2, and a connecting block 11 is threadedly mounted on the screw rod 10, and one side of the connecting block 11 is connected to one side of the sleeve 9.

[0025] In this embodiment, the shielding mechanism is used to shield the air. When in use, the screw 10 is rotated, the screw 10 will drive the connecting block 11 to move vertically, and the connecting block 11 will drive the sleeve 9 to slide vertically on the sampling head 1 until the top of the sleeve 9 contacts the top inner wall of the storage shell 2. After contact, the gas entering the sampling head 1 cannot enter the storage shell 2, which can reduce the contact between the sample and the external environment and reduce the risk of sample deterioration.

[0026] In a further preferred embodiment of the utility model, the cooling mechanism includes: a frame plate 12 welded on the storage shell 2, and a plurality of through holes are opened on the frame plate 12; a fan 13 fixedly mounted on the inner wall of the frame plate 12; a heat conducting plate 14 fixedly mounted on the inner wall of the mounting opening; and a semiconductor refrigeration plate 15 arranged inside the frame plate 12, and the cooling surface of the semiconductor refrigeration plate 15 is fixedly connected to one side of the heat conducting plate 14.

[0027] In this embodiment, the cooling mechanism is used to preserve the sample at a low temperature. When the sample needs to be preserved at a low temperature, the semiconductor refrigeration sheet 15 is started to start working. At the same time, the fan 13 also needs to be started to accelerate the flow rate of air in the frame plate 12. The low temperature generated by the semiconductor refrigeration sheet 15 is transferred to the water in the cavity 6 through the heat conduction plate 14. Through the cooling effect of the water, the food sample in the storage shell 2 can be cooled, and then the food sample in the storage shell 2 can be preserved at a low temperature, so that the sample will not deteriorate during transportation. At the same time, the operation of the fan 13 can speed up the heat dissipation rate of the heat dissipation surface of the semiconductor refrigeration sheet 15, so that the semiconductor refrigeration sheet 15 can maintain good stability during operation.

[0028] In a further preferred embodiment of the utility model, a protective net 16 is fixedly installed on one side of the frame plate 12, and a protective shell is fixedly installed on the top inner wall of the storage shell 2. The protective shell is located outside the motor 3 and is rotatably connected to the rotating shaft 4.

[0029] In this embodiment, a protective net 16 is fixedly installed on one side of the frame plate 12. The protective net 16 is added mainly to prevent the fan 13 from sucking in larger objects or foreign matter when working. The filtering effect of the protective net 16 ensures that the fan 13 can work continuously and stably. In addition, a protective shell is fixedly installed on the top inner wall of the storage shell 2. The protective shell is located outside the motor 3. The main function of the protective shell is to protect the motor 3 and prevent it from being disturbed by food samples during operation.

[0030] In a further preferred embodiment of the present invention, a temperature sensor 17 is fixedly mounted on one side of the storage shell 2 , and a detection probe of the temperature sensor 17 extends into the cavity 6 .

[0031] In this embodiment, the temperature sensor 17 is fixedly installed on one side of the storage shell 2, and its detection probe extends into the cavity 6. Since water is stored in the cavity 6, its temperature can directly affect the temperature environment inside the storage shell 2. Therefore, placing the detection probe of the temperature sensor 17 in the cavity 6 can directly and accurately monitor the temperature changes inside the storage shell 2. By real-time monitoring of the temperature inside the storage shell 2 and combining the adjustment of the cooling mechanism, we can ensure that the food sample is always in a low temperature state during the sampling and storage process. This can not only effectively inhibit the growth and activity of microorganisms and extend the shelf life of samples, but also avoid sample deterioration and nutrient loss caused by high temperature, thereby improving the accuracy and reliability of food safety testing.

[0032] In a further preferred embodiment of the utility model, a water changing pipe is fixedly installed on one side of the storage shell 2, the water changing pipe is connected to the cavity 6, and a cover body is threadedly installed on the water changing pipe.

[0033] In this embodiment, the water changing pipe is fixedly installed on one side of the storage shell 2 and is connected to the cavity 6. This design allows the user to easily drain the water in the cavity 6 or add new water by opening the cover on the water changing pipe.

[0034] In a further preferred embodiment of the present invention, a box is fixedly mounted on the top of the storage shell 2, a battery is arranged inside the box, and a controller is fixedly mounted on the top of the box.

[0035] In this embodiment, the battery serves as the power source of the device and can provide stable power support for components that require electrical energy, such as the motor 3, the fan 13, and the semiconductor cooling plate 15. This means that the sampling device can work independently without an external power supply, which greatly increases its flexibility and convenience of use. The addition of the controller makes the operation of the sampling device more intelligent and automated. The controller can connect and communicate with components such as the temperature sensor 17, the motor 3, the fan 13, and the semiconductor cooling plate 15. According to the real-time temperature data detected by the temperature sensor 17, the working state of the cooling mechanism is automatically adjusted to ensure that the interior of the storage shell 2 is always kept within an appropriate temperature range.

[0036] To sum up, compared with the related art, the two handles can facilitate personnel to insert the sampling head 1 into the food, and the starting motor 3 can drive the rotating shaft 4 to rotate, and the rotating shaft 4 will drive the spiral blade 5 to rotate, so that the food sample entering the sampling head 1 can be pushed into the storage shell 2 for storage, and the shielding mechanism can prevent the gas in the sampling head 1 from entering the storage shell 2, which can reduce the contact between the sample and the external environment and reduce the risk of sample deterioration. The cooling mechanism can cool the water in the cavity 6, and the food sample in the storage shell 2 can be cooled by the cooling effect of the water, so that the food sample in the storage shell 2 can be stored at low temperature, so that the sample will not deteriorate during transportation, and the accuracy and reliability of subsequent laboratory analysis can be improved, and the preservation effect is better. Through the coordinated use of the temperature sensor 17 and the controller, the working state of the cooling mechanism can be automatically controlled according to the water temperature in the cavity 6 to ensure that the inside of the storage shell 2 is always kept within an appropriate temperature range.
