Description

Technical Field

[0001] The utility model relates to the field of planktonic bacteria samplers, in particular to a microorganism collection and detection device. Background Art

[0002] The planktonic bacteria sampler is an efficient, portable and low-power device. Based on the Anderson impact principle, it can directly collect and reflect the indoor microbial concentration, and effectively sample and analyze suspended microorganisms in the air. The device is widely used in food safety, medical safety and environmental monitoring and other fields, providing important quality control and microbial monitoring tools for various industries. Its market price varies depending on the brand and function, but overall, the planktonic bacteria sampler plays an indispensable role in microbial sampling and analysis with its accuracy and efficiency.

[0003] When using existing planktonic bacteria samplers, it is usually necessary to remove the cover on the top air intake port for sampling. However, in actual operation, the process of removing the cover may cause the operator to forget to reinstall it, resulting in failure to effectively protect the air intake port after sampling is completed, and the cover may even be lost. This situation poses certain risks to the protection of the equipment and the accuracy of sampling. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a microbial collection and detection device to solve the technical problem that the operator may easily forget to remove the cover plate during the operation, resulting in failure to effectively protect the air intake position after the sampling is completed.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a microorganism collection and detection device, comprising a base and a device body, a protective shell is arranged on the top outer side of the device body, an air intake port is opened on the top of the protective shell, a protective mechanism is arranged on the inner side of the air intake port, the protective mechanism comprises a fixed blade, an expansion blade and a movable blade, a first limit strip and a second limit strip are arranged on the top surface of the fixed blade, a third limit strip and a fourth limit strip are arranged on the bottom surface of the movable blade, a first stop block is arranged on one side of the bottom surface of the expansion blade, and a second stop block is arranged on one side of the top surface of the expansion blade.

[0006] By adopting the above technical solution, when the movable blade is rotated, the third limit strip on its bottom surface will abut against the second stop block on the top surface of the extended blade, thereby driving the extended blade to rotate at an angle. At the same time, as the extended blade rotates, when the first stop block on its bottom surface abuts against the second limit strip on the top surface of the fixed blade, the rotation of the extended blade will be restricted. At this time, the three groups of fixed blades, extended blades and movable blades work together to cover the opening position of the air intake in a fan-shaped manner.

[0007] Furthermore, the fixed blades, the expansion blades and the movable blades are each provided in three, and are arranged in an equidistant ring along the central axis of the protective shell.

[0008] By adopting the above technical solution, the stability and coverage area of ​​the protective mechanism are ensured, and the three blades can be evenly distributed at the opening of the protective shell to form a balanced supporting structure, thereby improving the stability of the entire protective mechanism.

[0009] Furthermore, the fixed blades, the extended blades and the movable blades are rotatably connected to each other at their central axes.

[0010] By adopting the above technical solution, the blades can be flexibly unfolded and folded. Through a simple rotation action, the user can easily adjust the state of the protective mechanism to meet different usage requirements.

[0011] Furthermore, the first limiting strip and the fourth limiting strip are both used to limit the rotation angle position of the expansion blade.

[0012] By adopting the above technical solution, the accuracy and stability of the expansion blade during rotation are ensured, and the two limit strips can effectively limit the rotation angle of the expansion blade to prevent it from excessive rotation or deviation from the predetermined position.

[0013] Furthermore, the first abutment block abuts against the second limiting strip, and the second abutment block abuts against the third limiting strip, and is used to limit the extended blade when the fixed blade, the extended blade and the movable blade are rotated and unfolded.

[0014] By adopting the above technical solution, when the fixed blade, the expansion blade and the movable blade rotate and unfold, the abutment between the first stop block and the second limit strip, and the abutment between the second stop block and the third limit strip, jointly ensure the precise positioning and stability of the expansion blade during the unfolding process.

[0015] Furthermore, a control panel is disposed on the top surface of the base, and a handle is disposed on the top of the central axis of the movable blade to provide a user with a rotation force point for the movable blade.

[0016] By adopting the above technical solution, the control panel allows the user to conveniently operate and control the microbial collection and detection device, thereby improving the convenience and efficiency of the equipment. The control panel integrates various operation buttons and display interfaces, which facilitates the user to quickly set and adjust.

[0017] Furthermore, a support column is provided on one side of the base, and the top of the support column is rotatably connected to the device body through a connecting seat.

[0018] By adopting the above technical solution, a stable support is provided for the device body, ensuring the stability and balance of the microorganism collection and detection device. The solid structure of the support column can bear the weight of the device body and effectively distribute the weight to the base, preventing the device from tilting or shaking during use.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] The utility model uses a protective mechanism. After sampling is completed, the operator rotates the movable blade again. During the rotation, the third limit strip contacts the second stop block and drives the expansion blade to start rotating at an angle. Subsequently, the first stop block contacts the second limit strip, indicating that the protective mechanism is fully deployed. At this time, the three groups of fixed blades, expansion blades and movable blades work together to completely cover the opening position of the air intake port in a fan-shaped manner, providing effective protection for the sampling port. It not only avoids the problem that the traditional detachable cover is easily forgotten or lost, but also greatly improves the ease of use of the detection device. The sampling port can be easily opened and closed through a simple rotation operation, which is both convenient and practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0027] The following describes an embodiment of the utility model based on its overall structure.

[0028] Embodiment 1:

[0029] A microorganism collection and detection device, such as Figure 1-Figure 4 As shown, it includes a base 1 and a device body 3, a protective shell 5 is arranged on the outer side of the top of the device body 3, an air inlet 6 is opened on the top of the protective shell 5, and a protective mechanism 7 is arranged on the inner side of the air inlet 6, and the protective mechanism 7 includes a fixed blade 701, an expansion blade 702 and a movable blade 703, the top surface of the fixed blade 701 is provided with a first limit strip 704 and a second limit strip 705, the bottom surface of the movable blade 703 is provided with a third limit strip 708 and a fourth limit strip 709, a first stop block 706 is arranged on one side of the bottom surface of the expansion blade 702, and a second stop block 707 is arranged on one side of the top surface of the expansion blade 702. When the movable blade 703 is rotated, the third limit strip 704 and the second limit strip 705 on the bottom surface of the fixed blade 701 are provided. The strip 708 abuts against the second stop block 707 on the top surface of the extended blade 702, thereby driving the extended blade 702 to rotate at an angle. At the same time, as the extended blade 702 rotates, when the first stop block 706 on its bottom surface abuts against the second limit strip 705 on the top surface of the fixed blade 701, the rotation of the extended blade 702 will be restricted. At this time, the three groups of fixed blades 701, the extended blades 702 and the movable blades 703 work together to cover the opening position of the air intake port 6 in a fan-shaped manner, which not only provides an effective protection measure for the air intake port 6, but also is more convenient than the traditional detachable cover, avoiding the situation where the cover is forgotten or lost, thereby improving the ease of use of the entire device body 3.

[0030] See also Figure 1 , Figure 3 There are three fixed blades 701, three expansion blades 702 and three movable blades 703, which are arranged in an equidistant ring along the central axis of the protective shell 5, ensuring the stability and coverage area of ​​the protective mechanism 7. The three blades can be evenly distributed at the opening of the protective shell 5 to form a balanced support structure, which improves the stability of the entire protective mechanism 7. At the same time, these blades are arranged in an equidistant ring along the central axis of the protective shell 5. This layout not only makes the appearance more beautiful, but also ensures that the air intake 6 can be evenly and comprehensively protected. The equidistant arrangement also helps to disperse external force impact and enhance the pressure resistance of the overall structure, thereby extending the service life of the device.

[0031] See also Figure 1 , Figure 3The fixed blade 701, the extended blade 702 and the movable blade 703 are rotatably connected to each other at the central axis, so that the blades can be flexibly unfolded and folded. Through a simple rotation action, the user can easily adjust the state of the protective mechanism 7 to meet different usage requirements. At the same time, the rotating connection also enhances the adaptability and convenience of the device. When sampling, the blades can be folded to allow air to pass smoothly through the air inlet; after sampling is completed, the blades can be unfolded to form an effective protective barrier. This flexibility and convenience enable the device to achieve the best use effect in different scenarios.

[0032] See also Figure 3 , Figure 4 The first limit strip 704 and the fourth limit strip 709 are both used to limit the rotation angle position of the expansion blade 702, ensuring the accuracy and stability of the expansion blade 702 during the rotation process. The two limit strips can effectively limit the rotation angle of the expansion blade 702 to prevent it from excessive rotation or deviation from the predetermined position. At the same time, through the limiting effect of the first limit strip 704 and the fourth limit strip 709, it can be ensured that the protective mechanism 7 can achieve the expected effect when unfolding and folding, which not only improves the operability and ease of use of the device, but also enhances the reliability and durability of the entire protective mechanism 7.

[0033] See also Figure 3 , Figure 4 The first stop block 706 abuts against the second limiting strip 705, and the second stop block 707 abuts against the third limiting strip 708, which are used to limit the expansion blade 702 when the fixed blade 701, the expansion blade 702 and the movable blade 703 rotate and unfold. When the fixed blade 701, the expansion blade 702 and the movable blade 703 rotate and unfold, the abutment of the first stop block 706 and the second limiting strip 705, and the abutment of the second stop block 707 and the third limiting strip 708, together ensure the precise positioning and stability of the expansion blade 702 during the unfolding process. At the same time, this limiting setting enables the protection mechanism 7 to maintain a stable state after unfolding, and will not easily change its position due to external force or vibration, thereby ensuring the effective protection of the air inlet 6. This stability and reliability are crucial to the normal operation of the microorganism collection and detection device, and can avoid sampling errors or equipment damage caused by the instability of the protection mechanism.

[0034] Embodiment 2:

[0035] See also Figure 1 , Figure 2A control panel 2 is provided on the top surface of the base 1, and a handle 710 is provided on the top of the central axis of the movable blade 703, which is used to provide the user with a rotation force point for the movable blade 703. The control panel 2 allows the user to easily operate and control the microorganism collection and detection device, thereby improving the convenience and efficiency of the device. The control panel 2 integrates various operation buttons and display interfaces, which are convenient for the user to quickly set and adjust. At the same time, the handle 710 provided on the top of the central axis of the movable blade 703 provides the user with an intuitive rotation force point, so that the user can easily rotate the movable blade 703, thereby controlling the deployment and folding of the protective mechanism.

[0036] See also Figure 1 , Figure 2 A support column 4 is provided on one side of the base 1, and the top of the support column 4 is rotatably connected to the device body 3 through a connecting seat, providing a stable support for the device body 3, ensuring the stability and balance of the microorganism collection and detection device. The solid structure of the support column 4 can bear the weight of the device body and effectively distribute the weight to the base 1 to prevent the device from tilting or shaking during use. At the same time, the top of the support column 4 is rotatably connected to the device body 3 through the connecting seat, which allows the device body 3 to flexibly adjust the angle within a certain range, making it convenient for the user to adjust the working angle of the device according to actual needs, improving the adaptability and flexibility of the equipment, and thus better meeting the sampling and detection needs in different scenarios.

[0037] The implementation principle of the utility model is as follows: when sampling operation is required, first, the movable blade 703 is rotated by the handle 710, so that the positions of the fixed blade 701, the extended blade 702 and the movable blade 703 gradually overlap, wherein the first limiting strip 704 and the fourth limiting strip 709 are used to limit the extended blade 702, which is conducive to making the extended blade 702 completely overlap with the fixed blade 701 and the movable blade 703. At this time, the outer side of the fixed blade 701 is a through groove, which is used to provide the necessary air sampling operation during the sampling process;

[0038] When the sampling is completed, rotate the movable blade 703. With the gradual rotation, the third limit bar 708 abuts against the second stop block 707, and drives the extended blade 702 to rotate at an angle. Then, the first stop block 706 abuts against the second limit bar 705. At this time, using three groups of fixed blades 701, extended blades 702 and movable blades 703, it is beneficial to cover the opening position of the air inlet 6 in a fan shape, which is used to provide effective protection measures, which is beneficial to avoid the situation where the cover plate of the disassembly structure in the traditional form is forgotten and lost, and is beneficial to improving the convenience of use of the detection device.
