Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and in particular to a food toxin detection sample pretreatment device. Background Technology

[0002] Food toxin testing is a core component of the food safety assurance system. It employs various scientific methods to identify and measure different types of natural biological toxins and harmful chemical contaminants that may be present in food, ensuring that food meets safety standards and minimizing health risks to consumers.

[0003] In the sample pretreatment process for food toxin detection, the liquid or active ingredient to be tested is extracted from the sample. The extracted liquid needs to be transferred to a test tube and mixed with the corresponding reagents before testing can begin. However, currently, in this process, testing personnel need to manually shake the test tube to promote mixing of the sample and reagents. To ensure thorough mixing, prolonged shaking is often required, which undoubtedly increases the workload of the testing personnel.

[0004] Therefore, it is necessary to provide a food toxin detection sample pretreatment device to solve the above-mentioned technical problems. Utility Model Content

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] This utility model embodiment provides a food toxin detection sample pretreatment device, such as... Figure 1-3As shown, the food toxin detection sample pretreatment equipment includes: a base plate 1, a support plate 2 fixedly installed on the top of the base plate 1, a housing 3 fixedly installed on the support plate 2, and a liquid outlet pipe 4 fixedly installed on the bottom of the housing 3; a cylinder 5 fixedly installed on the housing 3, the cylinder 5 having multiple filter holes; a bracket 6 fixedly installed on the housing 3, an electric telescopic rod 7 fixedly installed on the bracket 6, a support shell 8 fixedly installed on the output rod of the electric telescopic rod 7, a pressure plate 9 for pressing food fixedly installed on the support shell 8, the pressure plate 9 being correspondingly arranged with the cylinder 5; a rotating shaft 10 rotatably installed on the pressure plate 9, multiple crushing blades 11 for crushing food fixedly installed on the rotating shaft 10; a drive motor 12 fixedly installed on the inner wall of the top of the support shell 8, the output shaft of the drive motor 12 being fixedly connected to the top end of the rotating shaft 10; and a reagent mixing mechanism assembled on the base plate 1 for pretreatment of food toxin detection samples.

[0019] In this embodiment, when using this device to pre-treat food toxin detection samples, first, a test tube containing the corresponding reagent is placed into the sleeve 15 of the reagent mixing mechanism. Then, the food sample to be tested is placed into the cylinder 5. These foods can be fruits and vegetables, etc. After placement, the electric telescopic rod 7 is activated to move the pressure plate 9 into the cylinder 5, allowing the pressure plate 9 to press the sample inside the cylinder 5. This allows the juice in the sample to flow out through multiple filter holes on the cylinder 5. To enhance the pressing effect, the drive motor 12 can be activated simultaneously to rotate the rotating shaft 10. The rotating shaft 10 drives multiple crushing blades 11 to rotate, which can crush the sample while pressing, improving the liquid output. The juice flowing out from multiple filter holes flows into the housing 3, and then drips from the liquid outlet pipe 4 into the test tube below. When all the required juice has entered the test tube, the reagent mixing mechanism can be activated to replace the testing personnel in shaking the test tube, so that the juice and reagent in the test tube can be mixed under shaking. During this mixing process, the operator can do other things, such as preparing the next sample to be processed, which can effectively reduce the labor intensity.

[0020] In a further preferred embodiment of the present invention, the reagent mixing mechanism includes: a bottom shell 13 fixedly installed on the top of the bottom plate 1, a plurality of springs 14 fixedly installed on the inner wall of the bottom shell 13, a sleeve 15 for placing test tubes fixedly installed on the plurality of springs 14, and a vibration motor 16 fixedly installed at the bottom of the sleeve 15.

[0021] In this embodiment, the reagent mixing mechanism is used to pre-treat food toxin detection samples. When in use, the vibration motor 16 is started. After the vibration motor 16 is started, it will drive the sleeve 15 to shake on multiple springs 14, thereby mixing the sample juice in the test tube with the reagent used for detection. This can effectively replace manual shaking and is more labor-saving.

[0022] In a further preferred embodiment of the present invention, the food toxin detection sample pretreatment equipment further includes a blocking mechanism installed on the support plate 2 for blocking test tubes.

[0023] In this embodiment, the use of the blocking mechanism can block the test tube and effectively prevent the test tube from falling off the sleeve 15 during shaking.

[0024] In a further preferred embodiment of the present invention, the blocking mechanism includes: a screw 18 rotatably mounted on the support plate 2, a handwheel fixedly mounted at one end of the screw 18, a connecting plate 19 threadedly mounted on the screw 18, a baffle 20 fixedly mounted on the connecting plate 19, the baffle 20 being slidably connected to the support plate 2, and a sponge pad fixedly mounted at the bottom of the baffle 20.

[0025] In this embodiment, when the blocking mechanism is in use, the screw 18 is turned by hand, which will cause the connecting plate 19 to move horizontally. The connecting plate 19 will cause the baffle 20 to slide on the support plate 2 until the sponge pad on the baffle 20 is above the test tube. Under the protection of the sponge pad, the test tube can be effectively prevented from falling off the sleeve 15 during shaking, thus ensuring the safety of the device in use.

[0026] In a further preferred embodiment of the present invention, a test tube rack 17 is fixedly installed on the top of the base plate 1, and the test tube rack 17 has a plurality of through holes for placing test tubes.

[0027] In this embodiment, the use of multiple through holes makes it convenient for testing personnel to place the test tubes to be used on the test tube rack 17.

[0028] In a further preferred embodiment of the present invention, the bracket 6 is configured as a U-shape, and a rubber layer is fixedly installed on the inner wall of the sleeve 15.

[0029] In this embodiment, the use of a rubber layer can increase the friction between the test tube and the sleeve 15, thereby improving the stability of the test tube in the sleeve 15.

[0030] In a further preferred embodiment of the present invention, an anti-slip pad is fixedly installed on the bottom of the base plate 1, and the liquid outlet pipe 4 is located directly above the sleeve 15.

[0031] In this embodiment, the use of an anti-slip mat allows the device to be placed stably on the table for use without slipping.

[0032] In summary, compared with related technologies, the use of the electric telescopic rod 7 enables the pressure plate 9 to press the food sample placed in the cylinder 5, allowing the juice in the sample to flow out from multiple filter holes. The use of the drive motor 12 enables the rotating shaft 10 to drive multiple crushing blades 11 to rotate, which can crush the sample while pressing it, thus improving the liquid output. The use of the liquid outlet pipe 4 allows the pressed juice to flow into a test tube containing the corresponding reagents. The use of the reagent mixing mechanism can replace the testing personnel in shaking the test tube, allowing the juice and reagents in the test tube to mix under shaking, realizing the pretreatment of food toxin detection samples. During this mixing process, the operator can do other things, such as preparing the next sample to be processed, which can effectively reduce labor intensity and is more convenient to use.

[0033] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
