[0002] Food inspection is to inspect the quality of food raw materials, auxiliary materials, semi-finished products, finished products and by-products to ensure that the product quality is qualified. The content of food inspection includes sensory detection of food, detection of nutrients, additives, and harmful substances in food, etc. When inspecting food, the extracted samples are usually put into test tubes, and then the solvents used for detection are added to the test tubes to fully mix the solvents with the samples before inspection. After the food inspection is completed, in order to enable the test tubes to be used subsequently, the test tubes need to be cleaned by a cleaning device.

[0003] Existing cleaning devices, such as the cleaning device with the publication number CN202320697782.3, during its use, it is necessary to insert the test tubes into the insertion cylinders one by one in an inverted manner, and then by starting the instrument, the brush and the nozzle are used to scrub and flush the inner wall of the test tube. Although this solution can clean the test tubes, it cannot clean multiple test tubes simultaneously, the cleaning efficiency is not high, and after a single test tube is removed, the operator may still need to bend down to observe the position of the insertion cylinder where the test tube is inserted in order to place the test tube at the designated position, further increasing the burden of the operator in cleaning the test tubes. Therefore, this solution proposes a test tube cleaning device for food inspection. Summary of the Utility Model

[0036] Please refer to Figures 1-5 , a test tube cleaning device for food inspection, including a cleaning box 1, an ultrasonic generator 2 is installed on the inner wall of the cleaning box 1, a transducer is installed at the bottom end of the cleaning box 1, a control panel 3 is installed at the front end of the cleaning box 1, a limiting frame 31 is fixedly connected to the inner wall of the cleaning box 1, and a placing assembly 4 is provided above the limiting frame 31, wherein;

[0037] The placement component 4 includes a carrying frame 41 provided on the upper side of the limiting frame 31. A filter screen 42 is fixedly connected between the inner walls of the carrying frame 41. Both the left and right sides of the carrying frame 41 are fixedly connected with upright columns 43. The upper ends of the upright columns 43 are fixedly connected with a support frame 44. A positioning member 45 is installed at the upper end of the filter screen 42.

[0038] During the use of this solution, in order to enable personnel to be more efficient when cleaning test tubes for food inspection, with a low labor burden and no easy damage to the inner wall of the test tubes. In this embodiment, the cavitation effect, acceleration effect, and rectilinear flow effect of ultrasonic waves in the liquid are used to directly and indirectly act on the liquid and dirt, so that the dirt layer is dispersed, emulsified, and peeled off to achieve the cleaning purpose, greatly enhancing the cleaning efficiency of the test tubes.

[0039] During the cleaning process, this solution can also replace the cleaning medium inside the cleaning tank 1, thereby further expanding the cleaning effect of the test tubes.

[0040] Moreover, in the ultrasonic cleaning mode of this solution, it can also avoid the phenomenon of scratches on the inner wall caused by the rotation of the brush when cleaning test tubes in the existing technology, and is not easy to cause damage to the test tubes during cleaning.

[0041] During the use of this solution, under the action of the positioning member 45, it can also position test tubes of different calibers, with a larger applicable range of test tubes, and it also makes the test tubes not easy to shake and collide with other objects during cleaning, greatly improving the protection of the test tubes during cleaning.

[0042] Compared with the prior art, this solution uses ultrasonic vibration to clean test tubes. Not only can it clean a larger number of test tubes at one time, but also it can clean more thoroughly, greatly improving the cleaning efficiency of personnel for test tubes. At the same time, it also avoids phenomena such as scratches and collisions on the inner wall of the test tubes during cleaning, enhancing the protection of the test tubes during cleaning.

[0043] During use, personnel can insert the test tubes one by one upside down above the positioning member 45, then place the carrying frame 41 on the surface of the limiting frame 31, then inject the cleaning medium into the cleaning tank 1, and then start the ultrasonic vibration cleaning work on the test tubes by controlling the ultrasonic generator 2 through the control panel 3, so as to disperse, emulsify, and peel off the dirt on the test tubes. And the peeled dirt continuously precipitates until it is at the bottom of the cleaning tank 1. Subsequently, personnel clean it uniformly. After the test tubes are cleaned, personnel lift the support frame 44 by hand to take out the entire placement component 4 from the inside of the cleaning tank 1 so as to remove the test tubes.

[0044] When the test tube is removed from the surface of the positioning member 45 in this solution, since the test tube is continuously in contact with the positioning member 45, when the test tube is pulled out upward, the positioning member 45 can still wipe clean the cleaning medium attached to the inside of the test tube, reducing the labor time for subsequent personnel to wipe the test tube and further improving the efficiency of test tube cleaning.

[0045] Please refer to Figures 1-3 , the positioning member 45 includes a support column 451 fixedly connected to the upper end of the filter screen 42. A support assembly 452 is installed at the upper end of the support column 451. Two symmetrically distributed clamping members 453 are movably connected inside the support assembly 452. A contraction member 454 is installed between the inner walls of the two clamping members 453.

[0046] More specifically: The clamping member 453 is made of elastic sponge material, and a plurality of uniformly distributed through holes 4531 are formed on the surface. The top end of the clamping member 453 is set to be a semi-circular angle.

[0047] During the use of this solution, when placing the test tube, the user can place the test tube upside down and place it above the clamping member 453. As the test tube continues to move downward, under the limitation of the tube mouth diameter, the two clamping members 453 move toward the side close to each other on the support assembly 452, and at the same time, the contraction member 454 contracts, thereby positioning the inverted test tube.

[0048] Subsequent personnel add the cleaning medium. The clamping member 453 adsorbs part of the cleaning medium. Then, with the ultrasonic vibration of the ultrasonic generator 2, the dirt on the inner wall of the test tube is peeled off, leaks out through the through holes 4531, and precipitates downward through the gap between the two clamping members 453.

[0049] At the same time, under the elastic sponge material of the clamping member 453, it is not easy to scratch the inner wall of the test tube during the cleaning process, enhancing the protection during test tube cleaning. And under the semi-chamfer at the top ends of the two clamping members 453, it is more convenient for the test tube to be inserted upside down.

[0050] Please refer to Figures 2-4 , the support assembly 452 includes a base 4521 fixedly connected to the upper end of the support column 451. A chute 4522 is formed inside the base 4521. Two sliders 4523 are movably connected between the inner walls of the chute 4522. The top ends of the sliders 4523 are fixedly connected to the clamping member 453.

[0051] More specifically: a through hole is provided at the bottom end of the base 4521, a connecting plate 4524 is fixedly connected to the central end between the inner walls of the through hole, blanking plates 4525 are fixedly connected to the left and right sides of the connecting plate 4524, the upper surface of the blanking plates 4525 is arranged in an inclined shape, and a plurality of uniformly distributed blanking holes 4526 are provided at the upper ends of the blanking plates 4525.

[0052] During the use of this solution, when the inverted test tube gradually moves down and sleeves on the surface of the clamping member 453, due to the pressing force, while the contraction member 454 contracts, the two sliders 4523 also slide synchronously towards the side close to each other. Then, during the test tube cleaning stage, the dirt on the inner wall of the test tube gradually precipitates. To prevent the precipitate from accumulating inside the base 4521 and causing blockage, which may lead to the phenomenon that the slider 4523 cannot slide. In this embodiment, a connecting plate 4524 is also embedded at the bottom end of the base 4521 and connected to the support column 451. Inclined blanking plates 4525 are installed on both sides of the connecting plate 4524, so that the dirt can slide down along the inclined surface and gradually precipitate and fall downward along the blanking holes 4526.

[0053] Please refer to Figures 2-3 and Figure 5 : The contraction member 454 includes an adapter sleeve 4541 fixedly connected to the inner wall of one side of the clamping member 453. A limiting block 4542 is movably connected between the inner walls of the adapter sleeve 4541. A spring 4543 is fixedly connected between the other end of the limiting block 4542 and the inner wall of the adapter sleeve 4541. One end of the limiting block 4542 is fixedly connected to an adapter rod 4544, and the adapter rod 4544 is fixedly connected to the inner wall of the other side of the clamping member 453.

[0054] During the use of this solution, when the test tube is inverted and moves down to press against the two clamping members 453, since the inner walls of the two clamping members 453 are respectively connected to the adapter rod 4544 and the adapter sleeve 4541, when the test tube is inverted and moves down, the adapter rod 4544 contracts into the adapter sleeve 4541 and presses the spring 4543 to compress. After the test tube is removed for cleaning later, the clamping member 453 is no longer limited by the limiting force to limit the contraction member 454. At this time, under the elastic return of the spring 4543, the adapter rod 4544 returns to its initial state, thereby displacing the clamping member 453 to both sides. At the same time, during the inversion of the test tube, the test tube can also be limited by being resisted and clamped.

[0055] The above-described embodiments merely represent certain implementation manners of the present utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
