For example, processes such as homogenization, dissolution, dilution, and mixing of food samples can all be carried out in test tubes. Many food testing methods require chemical reactions, such as detecting components such as sugars, proteins, and fats in food. Test tubes can be used for these reactions because they are resistant to chemical corrosion and are easy to control reaction conditions, so test tubes are widely used in food testing.

[0058] The present utility model will be further described below by way of embodiments, but the present utility model is not limited to the scope of the embodiments.

[0059] As Figure 1 and Figure 2 shown, a test tube cleaning device for food inspection includes a housing 1. The housing 1 includes a cylinder 11. A base 12 is fixed to the bottom of the cylinder 11. A cover plate 13 covers the top of the cylinder 11. First driving rods 14 are provided on both sides of the cylinder 11. The bottom end and the top end of the first driving rod 14 are respectively fixed to the base 12 and the cover plate 13. The first driving rod 14 is an electric push rod or a hydraulic push rod. A plurality of annularly distributed and vertically arranged mounting strip plates 17 are arranged inside the cylinder 11. The mounting strip plates 17 are fixed to the bottom side wall of the cover plate 13. The mounting strip plates 17 are slidably connected to guide rails 18, and the guide rails 18 are fixed to the inner wall of the cylinder 11;

[0060] A plurality of equally spaced mounting cavities 171 are formed on the surface of the mounting strip plate 17. A fixing assembly 4 for fixing a test tube is arranged inside the mounting cavity 171. The fixing assembly 4 is rotatably connected to the mounting cavity 171 with damping;

[0061] A rotatable bearing column 2, the bearing column 2 is rotatably connected to the center of the bottom side wall of the inner cavity of the cylinder 11 in the vertical direction;

[0062] An installation frame 22 is fixed to the bottom of the bearing column 2. A plurality of spray heads are fixed to the installation frame 22;

[0063] A cleaning structure that can be soaked first and then rinsed. The number of the cleaning structures is the same as that of the fixing assemblies 4. The cleaning structures are installed on the bearing column 2. The cleaning structures correspond to the fixing assemblies 4 one by one in the horizontal direction, and the cleaning structures and the fixing assemblies 4 are arranged alternately in the vertical direction;

[0064] A triggering assembly. The downwardly moving mounting strip plate 17 drives the triggering assembly to push the bearing column 2 to rotate through a lower pressing plate 172, so that the fixing assembly 4 and the corresponding cleaning structure are in a coincident position, facilitating the cleaning structure to clean the test tube on the corresponding fixing assembly 4;

[0065] A trigger block 3 with an inclined surface is disposed directly below the lower pressing plate 172. The trigger block 3 is connected to the bearing column 2 through a synchronizing rod 31. The trigger block 3 is connected to the bottom side wall of the cylinder body 11 through an arc-shaped sliding groove 111. One end of the trigger block 3 is connected to a spring, and the other end of the spring is connected to the inner wall of the sliding groove 111 or the cylinder body 11.

[0066] The inner wall of the test tube to be cleaned can be soaked first, and then the test tube is rotated to pour out the soaked waste liquid. The retractable rinsing part 5 extends into the interior of the test tube for effective rinsing, which improves the cleaning effect while ensuring the efficiency, and at the same time can clean test tubes of different lengths.

[0067] Embodiment 1

[0068] In this embodiment, the cleaning structure includes a soaking part and a rinsing part 5. The soaking part is located on one side of the top of the fixing component 4, and the rinsing part 5 is located on one side of the bottom of the fixing component 4;

[0069] The fixing component 4 drives the test tube with water to rotate from the soaking part to the rinsing part 5;

[0070] The rinsing part 5 is retractable.

[0071] The soaking part includes a water injection pipe 7 and a calibration part 6 for calibrating the position of the test tube mouth. The calibration part 6 includes a rotating rod 61 that rotates in the horizontal direction. The rotating rod 61 is rotatably connected to the end of a fixed rod 62. The fixed rod 62 is slidably connected to the bearing column 2 in the vertical direction. A calibration block 63 that can be lapped with the test tube is fixed to the end of the rotating rod 61. The top surface of the calibration block 63 is also of an inclined surface structure. An arc-shaped spring is provided at the connection between the rotating rod 61 and the fixed rod 62;

[0072] A lifting part 8 that can drive the fixed rod 62 to lift and lower is fixed to the bottom of the fixed rod 62;

[0073] A check member is also provided at the connection between the rotating rod 61 and the fixed rod 62, and the check member prevents the rotating rod 61 from rotating in the direction away from the corresponding height component;

[0074] The water injection pipe 7 constituting the soaking part is fixed to the rotating rod 61 of the soaking part above it, and the water injection pipe 7 is externally connected to a water pipe and a water pump.

[0075] In this embodiment, the installation strip 17 drives the lower pressing plate 172 to move downward until it reaches the inclined surface at the top of the trigger block 3 and then continues to move downward. During the downward movement, the lower pressing plate 172 pushes the trigger block 3 to slide inside the sliding groove 111, thereby driving the bearing column 2 to rotate on its own axis. The cleaning structure on the bearing column 2 also rotates accordingly until the soaking part and the flushing part 5 that make up the cleaning structure are respectively located at the top and bottom of the corresponding test tube. At this time, the lower pressing plate 172 continues to move downward until it disengages from the inclined surface of the trigger block 3 and abuts against the bottom of the cylinder body 11. The position of the installation strip 17 is fixed, that is, the position of the cleaning structure is fixed.

[0076] During the rotation of the bearing column 2 on its own axis, the calibration part 6 also rotates accordingly. The calibration block 63 on the calibration part 6 first abuts against the inclined test tube during the rotation process, and then as the lifting part 8 lifts, it drives the test tube to rotate upward until the tube opening of the test tube is aligned with the area where the water injection pipe 7 can inject water. At this time, the lifting part 8 stops lifting, and then the water pump connected to the water injection pipe 7 is started to inject water into the more inclined test tube to achieve soaking.

[0077] The check member includes a limiting plate 64. The limiting plate 64 is arranged on the side away from the corresponding fixing component 4. One end of the limiting plate 64 is rotatably connected to the surface of the fixing rod 62, and the other end of the limiting plate 64 abuts against the surface of the rotating rod 61. A torsion spring is arranged at the connection between the limiting plate 64 and the fixing rod 62;

[0078] One end of a transmission rope 65 is fixed on the limiting plate 64. The other end of the transmission rope 65 bypasses a plurality of guide wheels 66 and is connected to the second driving rod 21. The second driving rod 21 is fixed on the top of the bearing column 2. The guide wheels 66 play a role in guiding and limiting the transmission rope 65, that is, the guide wheels are distributed on the path passed by the transmission rope 65, and the guide wheels can be installed on the bearing column 2 and the corresponding fixing rod 62.

[0079] The second driving rod 21 is an electric push rod. When the second driving rod extends, it drives one end of the transmission rope 65. The transmission rope 65 drives the limiting plate 64 to rotate. At this time, the torsion spring on the limiting plate 64 is compressed, and the arc spring on the rotating rod 61 is stretched. The limiting plate 64 no longer limits the rotation direction of the rotating rod 61, and the check state is released.

[0080] The elastic force provided by the torsion spring on the limiting plate 64 is greater than that of the arc spring. At the same time, the elastic force provided by the torsion spring on the limiting plate 64 can keep the rotating rod 61 from rotating when pushing the test tube.

[0081] The elastic force provided by the arc spring enables the rotating rod 61 to rotate toward the side away from the test tube without being restricted by the limiting plate 64, avoiding affecting the rotation of the test tube. When the calibration block 63 rotates in the direction away from the corresponding test tube driven by the rotating rod 61, the test tube with water rotates downward to the limit position, and then flushing is carried out.

[0082] The rinsing part 5 includes an outer rod 51 and an inner rod 52. The inner rod 52 is sleeved in the inner cavity of the outer rod 51. A sliding piston 53 is fixed at the end of the inner rod 52. The sliding piston 53 is slidably connected to the side wall of the inner cavity of the outer rod 51. There is a sliding seal between the sliding piston 53 and the side wall of the inner cavity of the outer rod 51. Both the outer rod 51 and the inner rod 52 are hollow structures inside.

[0083] The sliding connection part between the end of the outer rod 51 and the surface of the inner rod 52 is a sliding seal structure. A plurality of water spraying holes are formed on the surface of the other end of the inner rod 52. A conical spring is sleeved on the surface of the inner rod 52. Due to the relatively flat characteristic of the conical spring, it is convenient for the inner rod 52 to be completely retracted into the inner rod 52, only exposing its end, so as to avoid interfering with the test tube during the rotation process. The two ends of the conical spring are respectively fixed to the exposed end of the inner rod 52 and the surface of the outer rod 51.

[0084] A through hole is formed on the sliding piston 53. A water passing switch part for closing and opening the through hole is arranged in the inner cavity at the end of the outer rod 51 and on the sliding piston 53. The through hole communicates the inner cavity of the outer rod 51 and the inner cavity of the inner rod 52. The end of the outer rod 51 is externally connected to a water pump through a water pipe.

[0085] The water passing switch part includes a sealing plate 55. The sealing plate 55 covers the through hole on the surface of the sliding piston 53 and is lapped with the surface of the sliding piston 53. Connecting shafts 56 are fixed at both ends of the sealing plate 55. The connecting shafts 56 are inserted into the mounting holes on the sliding piston 53. Springs are sleeved on the surfaces of the connecting shafts 56. The two ends of the springs are respectively fixed to the surface of the connecting shafts 56 and the side wall of the mounting holes.

[0086] Two or more ejector rods 54. The ejector rods 54 are fixed on the inner wall at the end of the outer rod 51, and the ejector rods 54 are arranged parallel to the inner rod 52. The ejector rods 54 can penetrate through the sliding piston 53 and are lapped with the sealing plate 55. The length of the ejector rods 54 is greater than the thickness of the sliding piston 53.

[0087] After the soaked test tube rotates downward to the limit position, the water used for soaking inside it flows out. At this time, the test tube mouth is aligned with the rinsing part 5.

[0088] Start the water pump connected to the outer rod 51. The water pump pumps water from the water pipe into the inner cavity of the outer rod 51. Since the sealing plate 55 covers the through hole, the water pushes the sliding piston 53 in the inner cavity of the outer rod 51 to slide towards the side of the inner rod 52, and the inner rod 52 also extends accordingly. The conical spring on the surface of the inner rod 52 is stretched and extends into the test tube. When the sliding piston 53 continues to move after moving to the position of the ejector rod 54, the ejector rod 54 penetrates through the sliding piston 53 and pushes the sealing plate 55 away from the through hole. The through hole is no longer blocked, and the water enters the cavity of the inner rod 52 through the through hole and is sprayed out from the water spraying holes, realizing the rinsing of the inside of the test tube.

[0089] After the flushing is completed, the water pump stops supplying water, and the inner rod 52 retracts under the action of the conical spring.

[0090] When the sealing plate 55 is pushed away from the through hole, the spring on the surface of the connecting shaft 56 is further stretched.

[0091] The lifting part 8 is connected to the corresponding calibration part 6 arranged in a vertical column. The lifting part 8 includes a pressure pipe 81 and a pressure-receiving pipe 82. The pressure pipe 81 and the pressure-receiving pipe 82 are interconnected through a soft conduit 83. The pressure pipe 81 is fixed on the bottom side wall of the base 12 below the corresponding mounting strip 17. A pressure piston 84 is slidably connected inside the pressure pipe 81. A transmission rod 85 is fixed at the center of the top of the pressure piston 84. The top of the transmission rod 85 penetrates through the bottom side walls of the base 12 and the cylinder 11 and extends into the inner cavity of the cylinder 11;

[0092] The top of the transmission rod 85 penetrates through the arc-shaped through groove on the trigger block 3 and is connected to the transmission plate 86. The transmission plate 86 can overlap with the lower pressing plate 172;

[0093] The pressure-receiving pipe 82 is fixed on the bearing column 2, and a pressure-receiving piston 87 is slidably connected inside the pressure-receiving pipe 82. A lifting rod 88 is fixed at the center of the top of the pressure-receiving piston 87. The top of the lifting rod 88 penetrates through the top side wall of the pressure-receiving pipe 82. The lifting rod 88 is connected to the fixed rod 62 through a cross bar;

[0094] A spring is sleeved on the surface of the transmission rod 85, and the two ends of the spring are respectively fixed on the transmission rod 85 and the inner wall of the pressure pipe.

[0095] When the lower pressing plate 172 moves downward, after contacting the top inclined surface of the trigger block 3, it contacts the transmission plate 86. The transmission plate 86 is pressed downward by the lower pressing plate 172, that is, the lower pressing plate 172 presses the transmission plate 86 and the trigger block 3 at the same time. When the trigger block 3 is completely pushed away by the lower pressing plate 172, the lower pressing plate 172 continues to move downward and presses the transmission plate 86 against the bottom side wall of the cylinder 11. During this process, the spring on the surface of the transmission rod 85 is stretched.

[0096] During the downward movement of the transmission plate 86, it drives the pressure piston 84 to move downward through the transmission rod 85. The pressure piston 84 presses the air in the pressure pipe 81 into the pressure-receiving pipe 82 through the conduit 83, thereby pushing the pressure-receiving piston 87 to move upward. The pressure-receiving piston 87 drives the lifting rod 88 to move upward to achieve lifting.

[0097] Embodiment 2

[0098] In this embodiment, the fixing component 4 includes a tubular fixing frame 41. Inside the fixing frame 41, there are two symmetric arc-shaped fixing blocks 43. The fixing blocks 43 are connected to the inner wall of the fixing frame 41 through telescopic rods 42 with springs. On the outer surface of the fixing frame 41, there is a connecting frame 44 fixed. On the surface of the connecting frame 44, there is a sleeve 45 rotatably sleeved on the surface of a rotating shaft 46. The rotating shaft 46 is fixed on the inner wall of the installation cavity 171;

[0099] A damping member is arranged at the connection between the rotating shaft 46 and the sleeve 45;

[0100] At the bottom of the fixing frame 41, there is a limiting rod located at the bottom of the fixing frame 41 to limit the downward rotation angle of the fixing frame 41.

[0101] The tail of the test tube is clamped between the two fixing blocks 43 to fix the test tube to be tested.

[0102] The damping member includes a mounting plate 47 fixed on the outer wall of the sleeve 45. A limiting threaded rod 48 penetrates through the mounting plate 47, and the limiting threaded rod 48 is threadedly connected to the mounting plate 47. The limiting threaded rod 48 can be lapped with the rotating shaft 46, and a damping block is fixed on the end of the limiting threaded rod 48 lapped with the rotating shaft 46. The damping block is made of soft rubber material. That is, through the damping block that can generate greater frictional force, frictional force is provided for the sleeve 45 to rotate on the surface of the rotating shaft 46, so that the fixing component 4 with an empty test tube does not rotate randomly without external forces other than gravity.
