Description

Technical Field

[0001] The invention relates to the technical field of microbial detection, and in particular to a device for separating and counting molds and yeasts in microbial detection. Background Art

[0002] In the context of the rapid development of modern science and technology and society, microbial testing has become an indispensable key link in many industries. Microorganisms are widely present in many fields such as food, medicine, environment, and agriculture. Among them, molds and yeasts are common and influential microorganisms, and their detection and analysis are particularly important.

[0003] Although some of the existing microbial detection equipment on the market has achieved automation or semi-automation to a certain extent, the functional integrity and practicality of the equipment specifically for the separation and counting of molds and yeasts still need to be improved. Many devices lack effective switching functions and cannot easily and flexibly switch between the overall observation state and the local observation state. The existing switching methods are mostly to change the focal length of the microscope to achieve the switch between regional observation and overall observation. Since the focal length of the microscope is adjusted slowly, it is impossible to quickly and accurately locate. At the same time, due to the activity of microorganisms, microorganisms will move during observation and counting, which can easily lead to inaccurate microbial technology and affect the accuracy and convenience of detection.

The lower end of the fill light 36 is fixedly connected to the slider 35. By controlling the on and off of the electromagnet 34 and the strength of the magnetism, the magnetic force between the electromagnet 34 and the slider 35 and the elastic restoring force of the second spring 37 cooperate with each other, the slider 35 will slide in the movable groove, thereby driving the fill light 36 to move. After the selection sleeve 28 rotates to the left, the fill light 36 is always directly below the selection sleeve 28.

[0033] Among them, it also includes a cleaning component, which includes a first motor 41 installed at the lower end of the workbench 1, the output shaft of the first motor 41 passes through the workbench 1 and is fixedly connected to a cleaning cylinder 38, the inner bottom and the inner bottom of the cleaning cylinder 38 are fixedly connected to a sponge block 40, and the inner wall of the cleaning cylinder 38 is embedded with a plurality of electric heating plates 39, the lower end of the conductive rod 15 is fixedly connected to a telescopic rod 18, the telescopic end of the telescopic rod 18 is fixedly connected to a pressure block 16, and the pressure block 16 is elastically connected to the conductive rod 15 through two first springs 17, and the upper end of the workbench 1 is embedded with a pressure sensor 14, and a controller is provided. After each device reset, the pressure sensor 14 is squeezed to generate an electrical signal transmitted to the controller, and the controller controls the first motor 41 and the electric heating plate 39 to run for a period of cleaning. Before each cleaning, it is necessary to control the first pneumatic rod 5 on the right to stretch so that the selection sleeve 28 moves into the cleaning cylinder 38. When cleaning is completed, it is necessary to control the first pneumatic rod 5 to shrink and reset.

[0034] The present invention can explain its functional principle through the following operation mode: first, place the culture dish containing the bacterial colony in the placement opening 8, start the second motor 42 at the lower end of the workbench 1, and the rotation of the output shaft of the second motor 42 will drive the vertical rod 3 fixedly connected thereto to rotate, and the two first pneumatic rods 5 at the lower end of the top plate 4 will move synchronously with the rotation of the vertical rod 3. When it is necessary to observe the whole, the sealing ring 6 and the first transparent plate 7 located on the left side are located directly above the culture dish, and the first pneumatic rod 5 is operated to extend its telescopic end, driving the sealing ring 6 and the first transparent plate 7 to move downward until the lower end of the sealing ring 6 is pressed against the upper end of the culture dish. At this time, the sample containing mold and yeast placed above the placement opening 8 can be observed as a whole through the first transparent plate 7 to understand the approximate distribution of the sample.

[0035] If the state of partial observation is to be switched, the first pneumatic rod 5 on the left side is operated to retract its telescopic end, driving the first transparent plate 7 to move upward, so that the placement opening 8 is completely exposed, and then the vertical rod 3 can be driven by the second motor 42 to rotate 180 degrees, so that the positions of the two sealing rings 6 are exchanged, and the selection component is rotated to the top of the target area. At this time, the fill light 36 is located directly below the selection sleeve 28, and the second pneumatic rod 29 is controlled to move first, so as to move the selection sleeve 28 to a suitable position in the lateral direction (first control the first pneumatic rod 5 on the left side to stretch, so that the sealing ring 6 moves down a certain distance, and the first gear 12 and the second gear 24 are engaged), and then the knob 11 is turned, and then the rotating ring 13 is driven to rotate through the first gear 12 and the plurality of tooth edges 27, so as to accurately align the selection sleeve 28 with the specific position where the target microorganism is located, and then the first pneumatic rod 5 is controlled to stretch, so that the selection sleeve 28 covers the specific position where the target microorganism is located (at this time, the lower end of the selection sleeve 28 is in contact with the inner bottom of the culture dish), so as to facilitate the subsequent separation and counting of molds and yeasts in the area.

[0036] During the rotation of the knob 11, since the first gear 12 and the second gear 24 are in a meshing state, the transmission rod 23 will be driven to rotate, and the fixed rod will be driven to rotate through the transmission assembly 22, so that the fill light 36 will rotate, and during the contraction of the second pneumatic rod 29, the conductive sheet 30 will move on the copper plate 31. Since the vertical rod 3 contacts the conductive rod 15 and the two conductive blocks 26 after rotation, the electromagnet 34 is in a powered state at this time (in the initial state, the selection sleeve 28 is located directly below the middle of the first transparent plate 7. At this time, the length of the copper plate 31 connected to the circuit is the longest, the resistance is the largest, and the current passing through the electromagnet 34 is close to zero). When the selection sleeve 28 moves, the length of the copper plate 31 connected to the circuit will continue to decrease, and the resistance of the connected circuit will continue to decrease. The current passing through the electromagnet 34 will increase, so that the attraction of the electromagnet 34 to the slider 35 will increase, so that the fill light 36 moves synchronously with the lateral movement of the selection sleeve 28, so that the fill light 36 is always located directly below the selection sleeve 28.

[0037] After each detection is completed, it is necessary to control the second motor 42 to run in reverse, so that the two sealing rings 6 are reset, and then the sealing ring 6 on the right is controlled to move downward, so that the selection sleeve 28 enters the cleaning cylinder 38. After resetting, due to the elastic action of the first spring 17, the pressure sensor 14 will be squeezed, thereby generating an electrical signal to be transmitted to the controller. The controller controls the first motor 41 and multiple electromagnetic plates 39 to run for a period of time, so that the cleaning cylinder 38 rotates, and then the sponge block 40 will be in full contact with the surface of the selection sleeve 28. The adsorption and wiping effect of the sponge block 40 can remove microorganisms, impurities, etc. attached thereto. At the same time, the operation of multiple electric heating plates 39 can not only dry the selection sleeve 28, but also use high temperature for sterilization to avoid the residue of microorganisms on the selection sleeve 28.

[0038] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
