Description

Technical Field

[0001] The present invention relates to the field of portable bacterial strain inoculation equipment, in particular to portable bacterial strain inoculation equipment. Background Art

[0002] In modern biological research and the biotechnology industry, inoculation is a crucial operational step. Whether in the production of various products through microbial fermentation, such as food fermentation, antibiotic production in the pharmaceutical field, or the preparation of biofertilizers in the agricultural field, accurate and efficient inoculation directly affects production efficiency, product quality, and the accuracy of experimental results.

[0003] Currently, there are many types of bacterial strain inoculation equipment on the market. Common ones include large-scale automated inoculation workstations, which usually have high-precision inoculation operation capabilities and can achieve large-scale, standardized bacterial strain inoculation. However, they are often large in size, integrating complex mechanical transmission, control systems, and sterile operating spaces, etc., and need to be fixedly installed on a dedicated laboratory bench or workshop site, and have strict requirements on the use environment. In addition, some small manual inoculation tools, although they have certain advantages in operational flexibility, most of them do not fully consider portability factors when they are designed. For example, common manual inoculation loops, inoculation needles, etc., and their accompanying alcohol lamps, culture medium storage devices, etc., are extremely inconvenient to carry when working outdoors or transferring them to different sites, and are easily damaged or contaminated during movement, making it difficult to meet the needs of scientific researchers for bacterial strain inoculation in scenarios such as field sampling and temporary experimental sites.

[0004] In summary, the existing bacterial strain inoculation equipment has obvious defects in portability, which greatly limits its application in diverse scenarios. There is an urgent need for a new type of portable bacterial strain inoculation equipment to solve this problem and meet the growing flexible operation needs of modern biological research and related industries. Summary of the Invention

[0005] In order to solve the problem that the existing equipment is inconvenient to carry, the present invention provides a convenient bacterial inoculation device.

[0006] In order to solve the above problems, the technical solution adopted by the present invention is: A portable bacterial strain inoculation device includes a box body with a glass door on the front side, a mounting platform inside the box body, a storage box installed on the right side of the mounting platform, a feed pump connected to the storage box, a feed pump installed on the left side of the mounting platform, a syringe connected to the feed pump, and the syringe installed on the bottom surface of the mounting platform. The portable bacterial strain inoculation device also includes a Z-axis translation mechanism and a two-axis translation mechanism; the mounting platform is installed on the two-axis translation mechanism; the Z-axis translation mechanism includes a lifting plate; and the Z-axis translation mechanism is arranged on the inner bottom surface of the box body. The design of the box body with a glass door not only facilitates observation of the inoculation operation inside the box body, but also maintains a relatively stable environment inside the box body to a certain extent, ensuring the safety and sterility of the inoculation process; the connection between the storage box and the feed pump can stably supply bacterial strains and other materials to the syringe, ensuring the continuity and accuracy of the inoculation process. The layout in which the feed pump is installed on the left side of the mounting platform and the syringe is installed on the bottom surface of the mounting platform makes rational use of space and makes the equipment structure compact. The Z-axis translation mechanism and the two-axis translation mechanism provide the mounting platform with multi-dimensional mobility. The Z-axis translation mechanism's lift plate enables vertical movement, while the two-axis translation mechanism allows horizontal movement. This allows for flexible adjustment of the mounting platform's position, facilitating precise inoculation operations and improving efficiency and accuracy. Furthermore, the entire device is housed in a convenient case for easy portability and transport, resolving the portability issues of existing equipment and making it suitable for a variety of work scenarios. The lift plate provides a stable operating platform for convenient placement of various inoculation-related items.

[0007] Preferably, the Z-axis parallel mechanism includes a concave plate mounted on the bottom of the box; two ball screws (1) are vertically mounted on the concave plate; the ball screws (1) extend through the concave plate and are connected to a motor (1); and the nuts of the ball screws (1) are connected to the lifting plate. The concave plate, mounted on the bottom of the box, provides a solid foundation for the entire Z-axis translation mechanism, capable of bearing the weight of the lifting plate and its mounted components, ensuring stability during operation, reducing shaking and displacement, and providing reliable positioning for bacterial inoculation operations. The design of a motor (1) driving the ball screw (1) to drive the lifting plate allows for flexible adjustment of the lifting range and speed of the lifting plate according to the actual needs of the inoculation operation, adapting to different types of bacterial inoculation operations and inoculation objects at different heights, demonstrating strong adaptability and versatility.

[0008] Preferably, the two-axis translation mechanism comprises an X-axis translation assembly and a Y-axis translation assembly. The X-axis translation assembly comprises two parallel ball screws (2). One end of each ball screw extends through the housing and is connected to a second motor. The nut of each ball screw is connected to a first slider. The Y-axis translation assembly is mounted on the two first sliders. The two parallel ball screws (2) are directly connected to the second motor. Leveraging the high precision and low friction of the ball screws, the first sliders achieve precise and efficient translation along the X-axis, ensuring precise position control of the mounting platform and significantly improving the accuracy of bacterial inoculation. The parallel ball screws (2) offer a stable structure and strong load-bearing capacity, stably supporting the Y-axis translation assembly, reducing the risk of shaking during translation and ensuring smooth operation. The simple structure simplifies maintenance, with components easily disassembled and assembled, reducing maintenance costs. The first slider serves as a connecting hub, conveniently integrating with the Y-axis translation assembly, giving the mounting platform dual-axis X- and Y-axis translation capability on the horizontal plane, expanding its operational range and adapting to a variety of bacterial inoculation scenarios.

[0009] Preferably, the Y-axis translation assembly includes a fixed seat hinged on slider one; a ball screw three is installed between the two fixed seats; one end of ball screw three is connected to motor three; ball screw three is installed at the bottom of the fixed seat; a guide rod is installed at the top of the fixed seat; the nut of ball screw three is connected to slider two; slider two is connected to the mounting platform via an angle deflection mechanism. The fixed seat connected to slider one is flexible and stable, providing reliable support for the overall structure. Ball screw three installed between the two fixed seats is connected to motor three and can efficiently drive slider two to move precisely in the Y-axis direction. In conjunction with the guide rod installed at the top of the fixed seat, it ensures smooth movement, further improving the accuracy of the mounting platform's position control in the Y-axis direction, thereby improving the accuracy of bacterial inoculation. Ball screw three is installed at the bottom of the fixed seat, with a reasonable layout and space saving. Slider 2 is connected to the mounting table through an angle deflection mechanism, which not only realizes translation in the Y-axis direction, but also gives the mounting table the angle adjustment function, so that the inoculation equipment can flexibly adjust its posture according to actual needs, greatly expanding the operational flexibility and scope of application, and meeting complex and diverse strain inoculation tasks.

[0010] Preferably, the angle deflection mechanism includes a hinged seat fixedly mounted on the lower side wall of the second slider; the lower part of the mounting platform is hinged on the hinged seat; the upper side wall of the second slider is hinged with an electric push rod; and the piston rod of the electric push rod is hinged to the upper side wall of the mounting platform. The hinged seat fixed to the lower side wall of the second slider is hinged to the lower part of the mounting platform, providing a stable rotation fulcrum for the mounting platform. The piston rod of the electric push rod hinged to the upper side wall of the second slider is hinged to the upper side wall of the mounting platform. The tilt angle of the mounting platform can be accurately controlled by retracting and extending the electric push rod. This design allows the portable bacterial strain inoculation device to flexibly adjust its posture. Whether facing inoculation objects of different shapes and angles, or adapting to complex and changing working environments, it can ensure that the inoculation operation is performed at the optimal angle, greatly improving the accuracy and efficiency of bacterial strain inoculation, and expanding the application range of the equipment in various scenarios.

[0011] Preferably, a battery pack is installed beneath the concave plate. This design frees the portable inoculation device from reliance on an external power source, allowing it to operate continuously and stably even in scenarios without an external power source, such as field sampling or temporary experimental sites, ensuring that inoculation tasks are not restricted by site power conditions. Furthermore, installing the battery pack beneath the concave plate rationally utilizes the device's internal space, making the overall layout more compact and further optimizing its portability, allowing researchers to conduct inoculation work anytime, anywhere.

Before the equipment is used, the ultraviolet germicidal lamp can thoroughly disinfect the interior of the box, effectively killing all possible microorganisms, reducing the risk of contamination by foreign bacteria in the inoculation environment, and ensuring that the inoculation operation is carried out in a nearly sterile environment, thereby significantly improving the success rate of bacterial inoculation and the reliability of experimental results and product quality. During periods of idle time, the ultraviolet germicidal lamp is periodically turned on to continuously maintain the cleanliness of the internal environment of the box, prevent bacterial growth, extend the service life of the equipment, and provide a long-term, stable, and safe environment for bacterial inoculation.

[0013] Preferably, a ventilation fan is installed on the side wall of the box; an air filter is installed inside the box in conjunction with the ventilation fan. On the one hand, the ventilation fan can promote the circulation of air in the box, maintain the freshness of the air inside the box, avoid local temperature and humidity imbalances in the box due to poor air circulation, and create more suitable environmental conditions for bacterial inoculation. On the other hand, the air filter can effectively filter the air entering the box, blocking dust, microorganisms and other impurities in the air, preventing them from entering the box and contaminating the bacterial strains. This further improves the cleanliness of the internal environment of the box, ensures the sterility of the inoculation process, and improves the quality and success rate of bacterial inoculation. At the same time, it also reduces the risk of damage to the equipment due to impurities entering the interior of the equipment, thereby extending the service life of the equipment.

[0014] Preferably, a display screen is provided on the top surface of the box. Through this screen, operators can obtain real-time information on key operating parameters of the equipment, such as the flow rate of the feed pump, the motor speed, and the coordinates of the inoculation position, facilitating timely understanding of the equipment status and precise control of the inoculation process. Furthermore, the display screen can also be used to display operating instructions, fault prompts, and other information, making it easier for operators to quickly get started and quickly troubleshoot and resolve problems, reducing operational difficulty and improving work efficiency, making inoculation more intelligent, convenient, and reliable.

[0015] Preferably, the controller of the display screen is provided with a USB interface. Firstly, it is convenient for data transmission, and various types of data during the operation of the equipment, such as vaccination operation records, equipment status parameters, etc., can be quickly exported to storage devices such as USB flash drives, which is convenient for subsequent data sorting, analysis and archiving, and provides strong data support for scientific research or production. Secondly, it is convenient for software updates and system maintenance. New control programs or system patches can be transferred to the controller through the USB interface, and the software system of the equipment can be upgraded in time to improve the performance and stability of the equipment, so that it can better adapt to different work needs. Thirdly, the setting of the interface can also be connected to external devices, such as connecting input devices such as a mouse and keyboard, to optimize the operating experience, improve the convenience and efficiency of operation, and make it easier for operators to control and set the equipment.

[0016] The advantages of the present invention are as follows: the glass door design of the housing facilitates observation of the inoculation process while maintaining a relatively stable environment within the housing, ensuring safety and sterility during the inoculation process. The connection between the container and the feed pump ensures a stable supply of bacteria and other materials to the syringe, ensuring continuity and accuracy during the inoculation process. The feed pump is mounted on the left side of the mounting platform, while the syringe is mounted on the bottom surface, effectively utilizing space and resulting in a compact device. The Z-axis translation mechanism and the two-axis translation mechanism provide the mounting platform with multi-dimensional mobility. The lift plate of the Z-axis translation mechanism enables vertical movement of the mounting platform, while the two-axis translation mechanism enables horizontal movement. This allows for flexible adjustment of the mounting platform's position, facilitating precise and efficient inoculation operations, and improving both efficiency and accuracy. Furthermore, the entire device is integrated into the housing, making it easy to carry and transport, addressing the portability issues of existing devices and making it suitable for a variety of work scenarios.

It can also continue to work stably in scenarios without an external power supply, such as field sampling and temporary experimental sites, ensuring that the bacterial inoculation task is not restricted by the site's power supply conditions.At the same time, the battery pack is installed under the concave plate 6, which rationally utilizes the internal space of the equipment, makes the overall layout more compact, further optimizes the portability of the equipment, and facilitates scientific researchers to carry out strain inoculation work anytime and anywhere.
