Food safety testing equipment is a device used to detect food microorganisms. Food microbial testing mainly detects the number and types of microorganisms in food through methods such as separation and cultivation of microorganisms, physiological and biochemical reactions, and microscopic examination, so as to reliably evaluate the quality of food and the hygiene conditions during the processing process.

[0003] In food testing, a food is usually tested for different items, including bacteria, viruses, fungi, actinomycetes, rickettsia, mycoplasma, chlamydia, spirochetes, etc. Due to the different test items, different cultures are required for testing. Usually, the food is divided into multiple portions and cultured for different items. Currently, the samples that need to be tested later may be agglomerated or precipitated due to the long waiting time, which leads to errors in the test results. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a microbiological inspection and observation device for food, which can shake untested samples to avoid sample agglomeration or precipitation.

[0024] A specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0025] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the technical solutions of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] In the description of the embodiments of the present invention, unless otherwise specified, “plurality” means two or more.

[0027] like Figures 1 to 6As shown, the present invention provides a microbiological inspection and observation device 1 for food, including an observation device 1, the observation device 1 is placed on a box 5, a shaking component is provided in the box 5, the shaking component includes a clamping member 2 and a vibration mechanism 3, the clamping member 2 is used to clamp a test tube, the clamping member 2 is connected to the vibration mechanism 3, the vibration mechanism 3 drives the clamping member 2 to shake, thereby shaking the test tube, the vibration mechanism 3 includes a rotating shaft 31, a guide rod 32, a rotating plate 33 and a motor 34, the rotating shaft 31 is arranged in the box 5 through a bracket, and the rotating shaft 31 is rotatably connected to the bracket, one end of the rotating shaft 31 is connected to the clamping member 2, and the other end of the rotating shaft 31 is provided with a through hole in the diameter direction, one end of the guide rod 32 is inserted in the through hole, and the guide rod 32 is slidably matched with the rotating shaft 31, and the other end of the guide rod 32 is arranged at a non-axial position of the rotating plate 33, the axis of the rotating plate 33 is connected to the transmission shaft of the motor 34, and the motor 34 drives the rotating plate 33 to rotate.

[0028] The present invention clamps the sample that has not been tested yet through the test tube through the clamping member 2, and the motor 34 drives the rotating plate 33 to rotate. Since the guide rod 32 is fixed at a non-axial position of the rotating plate 33, the guide rod 32 swings back and forth, and the guide rod 32 is slidably connected to the rotating shaft 31, so that the rotating shaft 31 rotates forward and reverse continuously, thereby driving the test tube to swing left and right, shaking the sample in the test tube to prevent the sample from agglomerating or settling.

[0029] like Figure 2 As shown, in the embodiment provided by the present invention, there are at least two shaking components, and each shaking component is rotatably connected to the lower wall of the placement box 5 through a turntable 6.

[0030] It can be understood that at least two shaking components are provided in order to be able to clamp multiple test tubes at one time and shake them mechanically at the same time.

[0031] It can be understood that each time a test tube is clamped, the turntable 6 can be rotated to continue clamping the next test tube through the shaking component, and the staff does not need to move.

[0032] In the embodiment provided by the present invention, the clamping member 2 includes a clamping base 21 and two clamping arms 22. The clamping base 21 is connected to the rotating shaft 31. The two clamping arms 22 are located on both sides of the clamping base 21, and the two clamping arms 22 are rotatably connected to the clamping base 21. The two clamping arms 22 are respectively provided with a first spring between the clamping base 21 to make the two clamping arms 22 approach each other.

[0033] like Figure 5 and Figure 6 As shown, in the embodiment provided by the present invention, a sealing component 4 is provided on the clamping base 21, and the sealing component 4 is used to seal the opening of the test tube to prevent the culture solution in the test tube from flowing out.

[0034] It is understandable that when the test tube is shaken, the sample in the test tube is likely to leak out. Mechanically sealing the test tube with the sealing assembly 4 can effectively prevent the sample from leaking out and also prevent external factors of the test tube from affecting the sample in the test tube.

[0035] In the embodiment provided by the present invention, the sealing assembly 4 includes a guide tube 41, a sealing pad 42 and a telescopic tube 43. The clamping base 21 is provided with a cavity, the guide tube 41 is provided with a channel along the length direction, the guide tube 41 is arranged on the clamping base 21, and the channel is connected with the cavity, one end of the telescopic tube 43 is located between the two clamping arms 22, and the other end of the telescopic tube 43 passes through the cavity and the channel in turn to be connected with the sealing pad 42.

[0036] The working principle is as follows: when the test tube is clamped, the test tube squeezes the telescopic tube 43, and the telescopic tube 43 moves in the channel of the guide tube 41, thereby pressing the sealing pad 42 on the opening of the test tube, thereby preventing the sample from leaking.

[0037] It should be noted that the telescopic tube 43 does not have a telescopic function itself, but is displaced in the guide tube 41 , and the end connected to the sealing gasket 42 is telescoped relative to the guide tube 41 .

[0038] In the embodiment provided by the present invention, the telescopic tube 43 includes a soft tube 432 and a hard tube 431. The hard tube 431 is located at one end of the two clamping arms 22. The hard tube 431 extends into the cavity of the clamping base 21. The part of the hard tube 431 located in the cavity is provided with a baffle along the circumferential direction. A second spring 432 is provided between the baffle and the inner wall of the clamping base 21. The second spring 432 allows the hard tube 431 to reset after being pressed.

[0039] It can be understood that the hard tube 431 is used to prevent the telescopic tube 43 from bending when the test tube is squeezed by the telescopic tube 43 .

[0040] Optionally, a shock-absorbing pad is provided at the place where the hard tube 431 contacts the test tube to prevent the hard tube 431 from breaking the test tube.

[0041] In the embodiment provided by the present invention, the guide tube 41 includes a straight tube 411 and a curved tube 412 , one end of the straight tube 411 is connected to the clamping base 21 , and the curved tube 412 is connected to the other end of the straight tube 411 .

[0042] It can be understood that the function of the bent tube 412 is to change the direction of the telescopic tube 43 so that the sealing gasket 42 can be pressed against the opening of the test tube.

[0043] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0044] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily realized. Therefore, without departing from the general concept defined by the claims and equivalent scope, the present invention is not limited to the specific details and the illustrations shown and described here.
