[0002] Food sample testing is the process of systematically analyzing and testing food samples to ensure food safety and quality, and compliance with relevant laws and standards, thereby protecting the public's food safety and consumer rights. According to the test method requirements, the sample needs to be processed into a uniform state, and then different testing equipment is selected according to the different test items to begin testing.

[0003] To improve sample homogenization efficiency, mechanical homogenization devices are often used to shake the solution in the test tube. Common homogenization devices mainly include a base with a turntable mounted on the base. The turntable is rotatably connected to the base and equipped with multiple tube clamps for placing sample test tubes. The drive element on the base controls the rotation of the turntable to shake the test tubes on the turntable.

[0024] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] according to Figure 1 、 2 As shown in Figures 3, 4, 5, and 6, a homogenizer for food sample testing is proposed in this embodiment, comprising a stand 1 and a fixed frame 2, the fixed frame 2 being fixedly connected to the upper end of the stand 1, a storage tray 5 being provided above the fixed frame 2, a plurality of test tube grooves 51 being provided at the upper end of the storage tray 5, the test tube grooves 51 being rotatably connected to the storage tray 5, and a driving member for controlling the rotation of the test tube grooves 51 being provided at the lower end of the storage tray 5;

[0026] The test tubes that need to be homogenized are placed in the corresponding test tube grooves 51 , and the driving member at the lower end of the storage tray 5 controls the test tube grooves 51 to rotate, thereby shaking the food samples in the test tubes.

[0027] A movable plate 3 is provided in the fixed frame 2, and the movable plate 3 is slidably connected to the fixed frame 2. A rotating shaft 54 ​​is fixedly connected to the lower end of the storage tray 5, and the rotating shaft 54 ​​is rotatably connected to the movable plate 3;

[0028] A power mechanism 4 for driving the movable plate 3 to move back and forth longitudinally is provided in the stand 1 , and a transmission member for driving the rotating shaft 54 ​​to rotate is provided at the upper end of the fixed frame 2 .

[0029] The power mechanism 4 pushes the movable plate 3 to move back and forth longitudinally, and the test tube groove barrel 51 on the placement tray 5 can also shake longitudinally during the rotation process. During the shaking process, the rotating shaft 54 ​​will also rotate with the entire placement tray 5, thereby increasing the centrifugal force of the liquid in the reagent tube on the placement tray 5 and improving the homogenization efficiency.

[0030] About drive components:

[0031] The drive assembly includes a first motor 52 and a motor bracket 53. The motor bracket 53 is fixedly connected to the lower end of the storage tray 5. The mounting end of the first motor 52 is fixedly connected to the motor bracket 53. The output end of the first motor 52 is fixedly connected to the lower end of the test tube trough 51. The rotation of the test tube trough 51 is controlled by the first motor 52. During rotation, the first motor 52 shakes the food sample tubes placed in the test tube trough 51.

[0032] The power assembly is used to push the movable plate 3 to move back and forth longitudinally in the fixed frame 2. Specifically, the power mechanism 4 includes a second motor 41. The mounting end of the second motor 41 is fixedly connected to the stand 1. The output end of the second motor 41 is fixedly connected to a crank 42. The crank 42 is rotated away from the end of the second motor 41 and is connected to a slider 43. The slider 43 is slidably connected to the second limit groove 31 opened at the lower end of the movable plate 3, and the two ends of the movable plate 3 are slidably connected to the first limit groove 21 opened on the inner side of the fixed frame 2.

[0033] The second motor 41 drives the crank 42 to rotate, and the rotation of the crank 42 drives the slider 43 to rotate together. The slider 43 slides along the second limiting groove 31 at the lower end of the movable plate 3 and continues to push the movable plate 3. The movable plate 3 moves back and forth longitudinally along the first limiting groove 21 on the inner side of the fixed frame 2. The first limiting groove 21 limits the movable plate 3 from both ends of the movable plate 3.

[0034] The transmission member is used to move the rotating shaft 54 ​​when the movable plate 3 moves longitudinally. Specifically, the transmission member includes a tooth plate 6 and a gear 61. The tooth plate 6 is placed on one side of the rotating shaft 54, and the gear 61 is sleeved on the outside of the rotating shaft 54. The gear 61 is fixedly connected to the rotating shaft 54, and the gear 61 is engaged with the tooth plate 6. The two ends of the tooth plate 6 are detachably connected to the fixed frame 2.

[0035] The gear 61 fixed on the outside of the rotating shaft 54 ​​is in a meshing state with the toothed plate 6. When the movable plate 3 moves back and forth longitudinally along the first limiting groove 21, the toothed plate 6 will cooperate with the teeth between the gear 61 to drive the rotating shaft 54 ​​to rotate. When the rotating shaft 54 ​​rotates, the storage tray 5 will also rotate.

[0036] To facilitate replacement of the tooth plate 6, a preferred embodiment includes bolt plates 7 at both ends of the tooth plate 6, which are fixedly connected to the tooth plate 6. A fixing bolt 71 is threadedly connected to the bolt plate 7, and the fixing bolt 71 is threadedly connected to a bolt hole provided in the upper end of the fixing frame 2. When removing the tooth plate 6 from the upper end of the fixing frame 2, the fixing bolt 71 on the bolt plate 7 is simply unscrewed from the bolt hole in the upper end of the fixing frame 2.

[0037] To prevent the test tubes placed in the test tube trough 51 from being thrown out of the test tube trough 51 due to the rotation of the storage tray 5 and the test tube trough 51, in a preferred embodiment, a plurality of rubber blocks 55 are provided on the inside of the test tube trough 51. The rubber blocks 55 are fixedly connected to the test tube trough 51, and a plurality of protrusions are provided on the surface of the test tube trough 51. After the test tube is inserted into the test tube trough 51, the rubber blocks 55 inside the test tube trough 51 will squeeze the test tube, increasing the damping of the test tube trough 51 on the rubber blocks 55, thereby preventing the test tube from falling out.

[0038] In order to improve the working stability of the homogenizer, in the preferred solution, a plurality of rubber pads are provided on the lower end surface of the stand 1, and the rubber pads are fixedly connected to the corners of the stand 1. They are used to increase the friction between the stand 1 and the table surface and improve the stability of the stand 1.

[0039] How this application works:

[0040] Reagent tubes to be homogenized are placed in corresponding test tube troughs 51. A drive member at the lower end of the storage tray 5 controls the rotation of the test tube troughs 51, thereby shaking the food samples within the test tubes. The power mechanism 4 propels the movable plate 3 in longitudinal reciprocating motion, causing the test tube troughs 51 on the storage tray 5 to shake longitudinally during rotation. During this shaking process, the rotating shaft 54 ​​also rotates the entire storage tray 5, increasing the centrifugal force on the liquids within the test tubes on the storage tray 5 and achieving higher homogenization efficiency.
