Description

Technical Field

[0001] This invention relates to the field of bacterial identification instruments, specifically to a portable bacterial identification instrument and its usage method. Background Technology

[0002] In current applications of microbial detection and public health monitoring, portable bacterial identification instruments have gradually become important equipment for rapid on-site screening due to their compact size, flexibility, and high detection efficiency. These instruments are widely used in various fields such as food safety, water quality monitoring, hospital infection control, and emergency public health event handling. However, existing portable bacterial identification instruments generally use microfluidic chips, reagent chambers, or sample mixing tanks to process samples. After completing a bacterial test, the instrument often retains test liquid, bacterial solutions, or biological reaction residues. If these residues are not removed promptly and thoroughly, they may not only affect the accuracy of subsequent sample tests and create a risk of cross-contamination, but may also breed bacteria or damage internal components, reducing the instrument's lifespan. Especially in field environments or where sterility is difficult to guarantee, operators often lack professional cleaning conditions or equipment, significantly reducing the efficiency of subsequent equipment use.

[0003] Furthermore, although some portable bacterial identification devices are equipped with automatic rinsing or simple cleaning functions, manual intervention is still required in most cases, such as replacing chips, disassembling chambers, and manually wiping residual liquid. This not only increases the operator's workload but also prolongs the operation process and testing cycle. In some designs, the cleaning area is located deep inside the device, making disassembly cumbersome and creating many blind spots for cleaning, leading to frequent false detections due to inadequate cleaning. In addition, in time-sensitive scenarios such as sudden outbreaks of epidemics and contamination incidents, the simpler and more efficient the operation process, the more valuable the device becomes. However, existing designs have not yet adequately addressed the technical bottleneck of "automatic liquid drainage after use to avoid residue." Therefore, there is an urgent need for a portable bacterial identification instrument with a more optimized structure, automatic residue drainage, and ease of repeated and rapid use to improve the device's continuous working capacity and the convenience of on-site testing.

[0004] In view of the above, in order to overcome the above technical problems, the present invention designs a portable bacterial identification instrument and a method of use, thereby solving the above technical problems. Summary of the Invention

[0005] The technical objective of this invention is to design a portable bacterial identification instrument and its usage method, which has a more optimized structure, can automatically remove residues, and is easy to use quickly and repeatedly.

[0006] To achieve the above-mentioned technical objectives, the present invention provides the following technical solution: A portable bacterial identification instrument includes multiple structural components such as a shell, a flip cover, a detection circuit board, a rotating disk, a mounting column, a rotating column, and a detection assembly. The shell is generally rectangular in shape with a hollow interior to house and protect the various electronic components and mechanical structures inside. The flip cover is hinged to the top of the shell and can be opened and closed as needed, facilitating the placement of samples into the detection assembly or the removal of the tested components. The detection circuit board, installed inside the shell, controls the electrical signal transmission and detection logic processing of the entire device and is the core control unit of the system. The rotating disk is located adjacent to the detection circuit board and can rotate around its center point, thereby driving the detection assembly to rotate.

[0007] A mounting column, a hollow cylindrical structure, is fixedly installed at the center of the rotating disk. A rotating column is fitted around its outer side to provide stable support and transmission connection for the detection component. The detection component is mounted on top of the mounting column, and its bottom is a detection base plate for placing bacterial samples. When the device is running, the detection circuit board controls the rotating disk to rotate, causing the mounting column and the upper detection component to rotate. This rotation generates a strong centrifugal force at the detection base plate, throwing any residual liquid in the test solution into the internal storage chamber, effectively separating any liquid remaining after the test. This design automatically performs preliminary cleaning of the test solution after each test, reducing manual cleaning steps, improving testing efficiency and the reusability of the equipment, making it particularly suitable for rapid field or on-site testing applications.

[0008] This device also includes a heat dissipation section, a ventilation section, and a cooling section to ensure temperature stability during operation. The heat dissipation section is located on the side of the casing and consists of multiple parallel-arranged heat dissipation fins made of highly thermally conductive materials (such as aluminum alloy or copper), which efficiently and quickly conduct internally generated heat to the outside air, effectively preventing overheating. The ventilation section is located at the top of the casing and consists of multiple neatly arranged strip-shaped through-holes to accelerate airflow within the device and improve overall heat dissipation efficiency. To further optimize the thermal management system, the cooling section is located next to the ventilation section and can be configured as a fan, electrothermal coil, or other active cooling device to assist the ventilation and heat dissipation systems, ensuring that the equipment maintains a normal and stable operating temperature during continuous operation or high-intensity testing, thus improving system reliability and lifespan.

[0009] The cooling unit is equipped with a set of miniature, high-efficiency fans that operate from the inside out, rapidly expelling hot air accumulated inside the device during operation. This helps lower the internal temperature and maintain stable operation. The fans feature a low-noise, low-power design, ensuring that detection accuracy and environmental quietness are not affected during prolonged operation. To further enhance the flexibility of ventilation and cooling, an adjustable rotary lever is located above the cooling unit. This lever can be rotated to different angles as needed, thereby adjusting the ventilation area of ​​the fan exhaust vents. By increasing or decreasing the ventilation opening, the airflow volume and direction can be controlled, achieving more precise regulation of the internal temperature. This structure not only improves cooling efficiency but also enhances the device's adaptability to different environmental conditions.

[0010] This device also includes a handle for easy carrying and data interaction, as well as a communication interface. The handle is securely mounted on the top of the housing and features an ergonomic, curved design with a non-slip textured surface, allowing for easy one-handed grip during outdoor testing or site transport, enhancing the device's convenience and mobility. The communication interface is located on the back of the housing and is used to connect external devices, such as computers, mobile terminals, or data acquisition systems. It supports USB, Type-C, or serial communication methods, enabling rapid transmission and remote analysis of test data, providing reliable support for subsequent processing and recording of on-site test results.

[0011] The upper end of the mounting post has a mounting hole for installing detection components or related connecting structures. This mounting hole has a cross-shaped design, allowing for stable mating with various shapes of connectors or fasteners, enhancing the installation firmness between components. The cross-shaped hole also facilitates positioning and adjustment, improving assembly accuracy and simplifying later maintenance and replacement operations.

[0012] The rotating column's structural design includes positioning holes, limiting grooves, and snap-fit ​​grooves, aiming to improve the overall component's connection stability and ease of installation. The positioning holes are located in the center of the rotating column, used for precise alignment with corresponding structures on the mounting column, ensuring coaxiality and smooth operation of the rotating component during rotation. The limiting grooves are located along the sides of the positioning holes, serving a dual function of guidance and limitation. They guide the component accurately into the designated position during installation or disassembly, effectively preventing misalignment or loosening due to offset. At the bottom of the limiting grooves is a snap-fit ​​groove with a fan-shaped cross-section. This structure enhances the locking strength during engagement, improves the tensile and torsional resistance of the rotating column when connected to other components, and ensures that the device does not loosen or slip during operation.

[0013] The detection assembly, consisting of a detection tray and a detection base plate, is a key structural component for receiving and processing bacterial samples. The detection tray is mounted on top of the mounting column and securely connected to ensure stability during equipment operation. The tray's concave cross-section, forming a shallow bowl shape, effectively prevents liquid sample spillage during testing and facilitates liquid concentration at the bottom during centrifugation, improving collection efficiency. The detection base plate, located at the bottom of the detection tray, is the reaction area directly supporting the bacterial sample. Its surface can be coated with detection reagents or microbial culture media as needed for bacterial identification, reaction, or preliminary separation. The base plate fits tightly to the detection tray, ensuring no leakage or displacement during centrifugation, cleaning, or sample testing, thus enhancing overall reliability and accuracy.

[0014] The detection assembly also includes structural components for residual liquid collection and temporary storage, including a collection tank, a collection channel, and a storage cavity, for effective management of residual liquid during the detection process. Specifically, the collection tank is located in the upper area of ​​the detection tray. Its function is to throw excess liquid or residual liquid from the liquid sample into the tank when the detection assembly rotates under centrifugal force, preventing it from flowing back to the detection base plate and ensuring the accuracy of the detection results. The collection channel is located directly below the collection tank, guiding the liquid downwards into the storage cavity. The storage cavity is located at the bottom of the collection channel and is mainly used to centrally store waste liquid generated during detection. Its cross-sectional shape is designed as a ring, which can be evenly distributed along the circumference of the detection assembly, saving space and increasing storage capacity. This ensures that waste liquid will not affect equipment operation or cause pollution during long-term or repeated use. This structural design greatly simplifies the cleaning process and improves detection efficiency and the continuous use capability of the equipment.

[0015] The detection assembly further includes a mating column, a mounting block, a connecting column, and a rotating locking block; the mating column is installed below the detection disk, the mounting block is installed below the mating column, the connecting column is arranged in a circumferential array around the mating column, and the rotating locking block is located at the bottom of the connecting column.

[0016] A method for using a portable bacterial identification instrument, the method being used in conjunction with the aforementioned portable bacterial identification instrument; the steps of the method are as follows: S1: The staff opens the flip cover and drips the liquid to be tested into the test base plate. The test circuit board performs the test and sends the test data to the display device through the communication interface or wireless transmission. S2: The heat dissipation unit is responsible for dissipating heat from the detection circuit board. The cooling unit can allow air to enter the interior of the housing from the outside through the ventilation opening, carry away the heat above the detection circuit board, and then exhaust it to the outside of the housing. S3: After the test is completed, the rotating disk drives the test component to rotate. The rotating block will rotate a certain angle in the slot and then lock to the bottom. S4: The test liquid on the test base plate enters the collection tank under the action of centrifugal force, and then enters the storage chamber through the collection channel for storage.

[0017] The beneficial effects of the present invention are as follows: (1) This invention achieves automatic cleaning of the portable bacterial identification instrument during multiple continuous tests through the rational design of the detection components and their internal structure, significantly improving ease of use and detection efficiency. Specifically, a rotating disk drives the detection components to rotate, and centrifugal force is used to automatically throw the residual liquid on the detection base plate into the collection tank, and then guide it into the annular storage chamber through the collection channel for storage. This avoids the tedious steps of manual cleaning of residual detection liquid in traditional equipment and effectively prevents cross-contamination. This not only reduces the labor intensity of operators and saves cleaning time, but also reduces the risk of detection errors caused by incomplete cleaning, greatly improving the reliability and accuracy of the instrument. In addition, the annular design of the storage chamber makes reasonable use of space, increases the storage capacity of waste liquid, and meets the needs of long-term continuous use.

[0018] (2) This invention also features a highly efficient heat dissipation and ventilation system to ensure stable temperature operation of the equipment under high load conditions. The heat dissipation unit uses multiple fins made of high thermal conductivity material, combined with the ventilation unit and fan cooling unit, to effectively accelerate the removal of internal heat and prevent overheating of electronic components, which could affect performance or shorten lifespan. This design ensures the stable operation of the detection circuit board, enabling the equipment to maintain excellent working condition in complex environments, improving the overall user experience and safety. In summary, this invention not only improves the detection efficiency and accuracy of the portable bacterial identification instrument, but also greatly enhances the practicality and adaptability of the equipment, making it suitable for rapid on-site detection and multi-scenario applications.

Detailed Implementation

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1-8 As shown, a portable bacterial identification instrument includes multiple structural components such as a shell 01, a flip cover 02, a detection circuit board 08, a rotating disk 09, a mounting post 10, a rotating post 11, and a detection assembly 12. The shell 01 is generally rectangular in shape with a hollow interior to house and protect various internal electronic components and mechanical structures. The flip cover 02 is hinged to the top of the shell 01 and can be opened and closed as needed, facilitating the placement of samples into the detection assembly 12 or the removal of tested components. The detection circuit board 08 is installed inside the shell 01 and controls the electrical signal transmission and detection logic processing of the entire device, serving as the core control unit of the system. The rotating disk 09 is located adjacent to the detection circuit board 08 and can rotate around its center point, thereby driving the detection assembly 12 to rotate.

[0024] A mounting column 10 is fixedly installed at the center of the rotating disk 09. The mounting column 10 is a hollow columnar structure, with a rotating column 11 sleeved on its outer side to assist in the stable support and transmission connection of the detection component 12. The detection component 12 is installed on top of the mounting column 10, and the bottom of the detection component 12 is a detection base plate 122 for placing bacterial samples. When the device is running, the detection circuit board 08 controls the rotating disk 09 to start rotating, causing the mounting column 10 and the upper detection component 12 to rotate. The rotational motion generates a strong centrifugal force at the detection base plate 122, causing the residual part of the detection liquid to be thrown into the storage chamber 125 inside the device, effectively separating the residual liquid during the detection process. This structural design can automatically complete the preliminary cleaning of the detection liquid after each detection, reducing manual cleaning steps, improving detection efficiency and the reusability of the equipment, and is particularly suitable for rapid field or on-site detection applications.

[0025] like Figure 1 As shown, this device also includes a heat dissipation section 03, a ventilation section 04, and a cooling section 05 to ensure the temperature stability of the equipment during operation. The heat dissipation section 03 is located on the side of the outer casing 01 and is composed of multiple parallel heat dissipation fins made of highly thermally conductive materials (such as aluminum alloy or copper), which efficiently and quickly conduct internally generated heat to the outside air, effectively preventing overheating. The ventilation section 04 is located above the outer casing 01 and consists of multiple neatly arranged strip-shaped through-holes to accelerate airflow within the equipment and improve overall heat dissipation efficiency. To further optimize the thermal management system, the cooling section 05 is located next to the ventilation section 04 and can be configured as a fan, electric cooling coil, or other active cooling device to assist the ventilation and heat dissipation systems, ensuring that the equipment maintains a normal and stable operating temperature during continuous operation or high-intensity testing, thus improving system reliability and lifespan.

[0026] The cooling unit 05 is equipped with a set of miniature high-efficiency fans. The fans operate from the inside out, rapidly expelling hot air accumulated inside the device during operation, thus helping to lower the internal temperature and maintain stable operation. The fans feature a low-noise, low-power design, ensuring that detection accuracy and environmental quietness are not affected during prolonged operation. To further enhance the flexibility of ventilation and cooling, an adjustable rotary lever is located above the cooling unit 05. This lever can be rotated to different angles as needed, thereby adjusting the ventilation area of ​​the fan exhaust vents. By increasing or decreasing the ventilation opening, the airflow volume and direction can be controlled, achieving more precise temperature regulation. This structure not only improves cooling efficiency but also enhances the device's adaptability to different environmental conditions.

[0027] like Figure 1-2As shown, this device also includes a handle 06 for easy carrying and data interaction, and a communication interface 07. The handle 06 is securely mounted on the top of the housing 01, featuring an ergonomic arc-shaped design and a non-slip textured surface, allowing for easy one-handed grip during outdoor testing or site transport, enhancing the device's convenience and mobility. The communication interface 07 is located on the back of the housing 01 and is used to connect external devices, such as computers, mobile terminals, or data acquisition systems. It supports USB, Type-C, or serial communication methods, enabling rapid transmission and remote analysis of test data, providing reliable support for subsequent processing and recording of on-site test results.

[0028] like Figure 4 As shown, the upper end of the mounting post 10 has a mounting hole 101 for mounting the detection component 12 or related connecting structures. The mounting hole 101 has a cross-shaped design, allowing for stable engagement with various shapes of connectors or fasteners, enhancing the installation firmness between components. The cross-shaped hole also facilitates positioning and adjustment, improving assembly accuracy and simplifying later maintenance and replacement operations.

[0029] like Figure 5 As shown, the rotating column 11 is structurally designed with a positioning hole 111, a limiting groove 112, and a snap-fit ​​groove 113, aiming to improve the connection stability and ease of installation of the overall assembly. The positioning hole 111 is located in the middle of the rotating column 11, used for precise docking with the corresponding structure on the mounting column 10 to achieve axial alignment and ensure the coaxiality and smooth operation of the rotating assembly during rotation. The limiting groove 112 is located along the side of the positioning hole 111, serving a dual function of guidance and limitation. It guides the component to accurately slide into the designated position during installation or disassembly, effectively preventing misalignment or loosening due to offset. At the bottom of the limiting groove 112, a snap-fit ​​groove 113 is provided. The cross-sectional shape of the snap-fit ​​groove 113 is designed as a fan-shaped ring. This structure enhances the fit and improves the tensile and torsional resistance of the rotating column 11 when connected to other components, ensuring that the device does not loosen or slide during operation.

[0030] like Figure 6As shown, the detection assembly 12 consists of a detection tray 121 and a detection base plate 122, and is a key structural component for receiving and processing bacterial samples. The detection tray 121 is mounted on the top of the mounting column 10, and its secure connection ensures stability during equipment operation. The detection tray 121 has a concave cross-sectional shape, forming a shallow bowl-like structure, which effectively prevents liquid sample spillage during detection and helps the liquid concentrate at the bottom during centrifugation, improving the collection efficiency of the detection liquid. The detection base plate 122 is installed at the bottom of the detection tray 121 and is the reaction area that directly supports the bacterial sample. Its surface can be coated with detection reagents or microbial culture media as needed for bacterial identification, reaction, or preliminary separation operations. The base plate fits tightly to the detection tray 121, ensuring no leakage or displacement during centrifugation cleaning or sample detection, thus improving the overall reliability and accuracy.

[0031] like Figure 7 As shown, the detection component 12 also includes structural parts for residual liquid collection and temporary storage, including a collection tank 123, a collection channel 124, and a storage cavity 125, for effective management of residual liquid during the detection process. Specifically, the collection tank 123 is located in the upper area of ​​the detection plate 121. Its function is to throw excess liquid or residual liquid after reaction into the tank when the detection component 12 rotates under centrifugal force, preventing it from flowing back to the detection base plate 122 and ensuring the accuracy of the detection results. The collection channel 124 is located directly below the collection tank 123. Through the guiding effect of the channel, the liquid flows smoothly down into the storage cavity 125. The storage cavity 125 is located at the bottom of the collection channel 124 and is mainly used for centralized storage of waste liquid generated during detection. Its cross-sectional shape is designed as a ring, which can be evenly distributed along the circumference of the detection component 12, saving space and increasing storage capacity, ensuring that the equipment operation will not be affected or contaminated by waste liquid overflow during long-term or multiple uses. This structural design greatly simplifies the cleaning process and improves testing efficiency and the ability to use the equipment continuously.

[0032] like Figure 8 As shown, the detection component 12 further includes a mating post 126, a mounting block 127, a connecting post 128, and a rotating locking block 129; the mating post 126 is installed below the detection disk 121, the mounting block 127 is installed below the mating post 126, the connecting post 128 is arranged in a circumferential array around the mating post 126, and the rotating locking block 129 is located at the bottom of the connecting post 128.

[0033] A method for using a portable bacterial identification instrument, the method being used in conjunction with the aforementioned portable bacterial identification instrument; the steps of the method are as follows: S1: The staff opens the flip cover 02, drips the liquid to be tested into the test base plate 122, the test circuit board 08 performs the test, and sends the test data to the display device through the communication interface 07 or wireless transmission. S2: The heat dissipation unit 03 is responsible for dissipating heat from the detection circuit board 08. The cooling unit 05 can allow air to enter the interior of the housing 01 from the outside through the ventilation opening, carry away the heat above the detection circuit board 08, and then exhaust it to the outside of the housing 01. S3: After the test is completed, the rotating disk 09 drives the testing component 12 to rotate. The rotating block 129 will rotate a certain angle in the locking groove 113 and then lock to the bottom. S4: The detection liquid on the detection base plate 122 enters the collection tank 123 under the action of centrifugal force, and enters the storage chamber 125 through the collection channel 124 for storage.

[0034] During operation, the operator first opens the instrument's flip cover 02 and drips the liquid sample to be tested into the detection base plate 122 of the detection component 12. At this time, the internal detection circuit board 08 begins to analyze and test the sample. The obtained data is transmitted to an external display device via the communication interface 07 or a wireless transmission module for real-time viewing of the test results. Simultaneously, the heat dissipation unit 03 activates, utilizing high-efficiency heat dissipation fins mounted on the side of the outer casing 01 in conjunction with the ventilation system of the cooling unit 05 to draw external air into the device. After passing over the detection circuit board 08 and carrying away the generated heat, the air is then exhausted to the outside, ensuring stable temperature during operation. After testing, the rotating disk 09 drives the detection component 12 to rotate. The rotating locking block 129 rotates to a preset angle in the locking groove 113 and then locks at the bottom, fixing the component's position. During rotation, the liquid on the detection base plate 122 is thrown into the collection tank 123 on the detection plate 121 under the action of centrifugal force, and then flows into the annular storage chamber 125 below through the collection channel 124, completing the effective collection and storage of residual liquid, realizing the automatic cleaning of the equipment in preparation for the next test.
