Detailed implementation manners

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] Embodiment: As Figures 1 - 5 and Figure 8 shown, a self-sterilizing microorganism bacteria culture and propagation inoculation instrument of the present invention includes a machine body 1. A fixed pressing part 5 is provided on the upper part of the machine body 1. The machine body 1 is divided into a sterilization chamber and an installation chamber by a partition board. A sterilization module 11 capable of killing bacteria is provided in the sterilization chamber. A cover plate is provided on the top of the sterilization chamber, and at least two T-shaped positioning cylinders 12 communicating with the sterilization chamber are provided on the cover plate; the sterilization module 11 can sterilize multiple inoculation tools 3 at the same time; Above the sterilization module 11, at least two inoculation mechanisms are provided, which are composed of a transmission support 6, a T-shaped movable part 8 connected to the transmission support 6 through a movable connection component, and an inoculation tool 3 connected to the T-shaped movable part 8. The transmission support 6 includes a connection seat 61, and a fixed component 7 for fixing the T-shaped movable part 8 by cooperating with the fixed pressing part 5 is provided on the connection seat 61; A suspension cylinder 2 capable of extending into the sterilization chamber is provided in the T-shaped positioning cylinder 12; the provided machine body 1 and the suspension cylinder 2 can also be used as storage racks to store the inoculation tools 3; An elevating mechanism for driving the inoculation mechanism to lift is provided in the installation chamber, and the moving body of the elevating mechanism is connected to the connection seat 61 through a transmission arm 4.

[0026] In this embodiment, since more than one inoculation mechanism and suspension cylinder 2 are provided, the inoculation tools 3 can be used alternately, avoiding the time waste caused by waiting for sterilization. Especially for the streaking method that requires multiple streaks, it can greatly save time and improve work efficiency.

[0027] In this embodiment, the lifting mechanism can be an electric linear module. One end of the transmission arm 4 is fixed to the slide seat (i.e., the moving body) of the electric linear module, and the other end is fixed to the connecting seat 61. Therefore, the inoculation mechanism can be driven to lift by the lifting mechanism.

[0028] In addition, the sterilization module 11 can be one of an electric hot plate, an electric heating wire, an electric heating tube, and an infrared lamp. By supplying power to the electric hot plate, the electric heating wire, or the electric heating tube, high temperature is generated to kill bacteria. At this time, the hanging cylinder 2 is made of a high thermal conductivity material, such as copper, stainless steel, etc. The inoculation tool 3 is irradiated by the infrared rays generated by the infrared lamp to heat the inoculation tool 3, and the purpose of killing bacteria can also be achieved, and the heating speed is fast. At this time, the hanging cylinder 2 is made of a colorless transparent material, such as glass, etc.

[0029] In this embodiment, components such as a power interface, a controller, a button module, and a voice reminder module also need to be provided. The above components can all be arranged on the machine body 1. The controller is electrically connected to the power interface, the button module, the voice reminder module, and the lifting mechanism. The voice reminder module is used to remind the user how long it will take to unlock the inoculation tool 3 and perform a countdown. The specific installation positions and installation methods of the power interface, the controller, the button module, and the voice reminder module are not limited here, so they are not marked in the drawings.

[0030] In addition, a distance sensor electrically connected to the controller can be set to detect the distance between the connecting seat 61 and the fixed pressing member 5. The controller receives the detection signal from the distance sensor, processes and analyzes the detection signal to judge how far the distance is between the connecting seat 61 and the fixed pressing member 5 and how much time it will take to unlock the inoculation tool 3. Other sensors can also be used, such as a speed sensor, but the speed sensor needs to be set on the connecting seat 61. Sensors can also not be set, but the speed at which the lifting mechanism drives the inoculation mechanism can be used for determination.

[0031] Among them, as Figures 8 - 11 shown, the fixing component 7 includes a fixing bracket 71, a movable member 79 installed inside the fixing bracket 71, and a plugging column 74 connected to the movable member 79 through a reinforcing plate 75. A movable rod 73 that can be pressed downward by the fixed pressing member 5 penetrates through the top plate of the fixing bracket 71. A matching cylinder 76 is provided at the lower end of the movable rod 73, and the lower end of the matching cylinder 76 is provided as an inclined surface. A connecting spring 72 for supporting the movable rod 73 and enabling the movable rod 73 to reset is sleeved outside the movable rod 73. And clips 78 are symmetrically provided at one end of the top plate of the fixing bracket 71, and a limiting boss is provided at the bottom of the bottom plate of the fixing bracket 71. T-shaped sliding strips 77 are symmetrically provided at one end of the limiting boss. The connecting part two can be effectively prevented from deforming through the reinforcing plate 75.

[0032] Specifically, as Figures 8 - 11As shown, the movable member 79 includes a first connecting portion, a second connecting portion connected to the fixed bracket 71, an elastic portion 791, and a rigid abutting portion 792 abutting against the inclined surface. One end of the elastic portion 791 is bent upward and connected to the lower end of the first connecting portion, the other end is bent downward and connected to the upper end of the rigid abutting portion 792. The lower end of the rigid abutting portion 792 is bent upward and connected to the lower end of the second connecting portion. A through hole for installing the insertion column 74 is formed in the second connecting portion. The through hole is used to install the insertion column 74, facilitating the connection between the insertion column 74 and the second connecting portion.

[0033] The inoculation mechanism is driven by the lifting mechanism to move upward. After the movable rod 73 contacts the fixed pressing member 5, the movable rod 73 moves downward due to pressure, causing the connecting spring 72 to be in a stretched state. The movable rod 73 drives the fitting cylinder 76 to move downward. The fitting cylinder 76 pushes the rigid abutting portion 792. The rigid abutting portion 792 squeezes the elastic portion 791 and drives the insertion column 74 to disengage from the insertion hole 81, completing the unlocking operation of the inoculation tool 3. After one inoculation is completed and the used inoculation tool 3 is fixed, the operator can activate another lifting mechanism to remove another inoculation tool 3 from the corresponding suspension cylinder 2, which is conducive to the alternate use of the inoculation tool 3.

[0034] Among them, as Figure 4 , Figure 7 and Figure 8 shown, the T-shaped movable member 8 is a T-shaped column. A threaded blind hole is formed in the large-diameter end of the T-shaped column. Symmetric positioning chutes 83 and an insertion hole 81 for inserting the insertion column 74 are provided on the outer wall of the small-diameter end. A hanging ring 82 is rotatably connected to the end of the small-diameter end. One end of the holding portion of the inoculation tool 3 is provided with a threaded joint 31 screwed into the threaded blind hole; the inoculation tool 3 is connected to the T-shaped movable member 8 by screwing the threaded joint 31 into the threaded blind hole.

[0035] In addition, the inoculation tool 3 is one or several of an inoculation loop, an inoculation needle, an inoculation spatula, and an inoculation rod, so that different inoculation methods can be applied for inoculation, enabling the operator to select different inoculation tools 3 according to needs, which is very flexible.

[0036] Among them, as Figure 7 and Figure 8 shown, the movable connection assembly includes a spiral telescopic rope 9. One end of the spiral telescopic rope 9 is connected with a buckle ring that can be hung on the hanging ring 82, and the other end is connected with a T-shaped screw rod. Through the buckle ring that can be hung on the hanging ring 82 and the T-shaped screw rod, the spiral telescopic rope 9 is connected to the T-shaped movable member 8 and the connecting cylinder 62, and the disassembly is convenient; the spiral telescopic rope 9 can effectively prevent the loss of the T-shaped movable member 8 or even the inoculation tool 3, and the telescopic property of the spiral telescopic rope 9 will not hinder the bacterial inoculation.

[0037] Among them, as Figure 4 , Figure 5 and Figure 8 shown, the transmission support 6 further includes a connecting cylinder 62 fixed to the center of the top of the connecting seat 61. An installation hole for installing a T-shaped screw is provided at the top of the connecting cylinder 62, and the T-shaped screw is fixed to the connecting cylinder 62 through a nut. The connecting cylinder 62 provides support for the installation of the spiral telescopic rope 9, and the connecting cylinder 62 can hide the spiral telescopic rope 9, making it more beautiful.

[0038] Among them, as Figure 5 and Figure 6 shown, a sliding through hole 63 that is slidably matched with the small-diameter end of the T-shaped movable part 8 is provided at the center of the connecting seat 61. The sliding through hole 63 is connected to the installation groove 64 through a communication hole that is slidably matched with the insertion column 74. Symmetrically arranged on the inner wall of the sliding through hole 63 are positioning ridges that are slidably matched with the positioning sliding grooves 83, and two card slots 66 that are connected to the installation groove 64 and can be clamped with the clip 78 are provided above the communication hole; through the clamping of the clip 78 and the card slot 66, the stability of the installation of the fixed support 71 is improved; through the sliding fit of the positioning ridges and the positioning sliding grooves 83, the T-shaped movable part 8 is quickly positioned.

[0039] Among them, as Figures 3 - 6 shown, installation grooves 64 for installing the fixed support 71 are symmetrically provided on the connecting seat 61. A positioning table 65 is provided in the installation groove 64. A T-shaped sliding groove that is slidably matched with the T-shaped sliding bar 77 is provided on the positioning table 65, and a pressing ring 67 is further provided at the bottom of the connecting seat 61. Through cooperation with the T-shaped positioning cylinder 12, the suspension cylinder 2 is fixed; through the sliding fit of the T-shaped sliding bar 77 and the T-shaped sliding groove, the fixed support 71 is quickly positioned.

[0040] Among them, as Figure 1 and Figure 2 shown, a plurality of avoidance holes for avoiding the connecting cylinder 62 are provided on the fixed pressing member 5. The shape of the avoidance holes can be C-shaped, U-shaped, etc. The specific shape of the avoidance holes is not limited here, as long as the connecting cylinder 62 can be avoided so that the fixed pressing member 5 does not block the connecting cylinder 62.

[0041] Among them, as Figure 2 and Figure 3 shown, a limiting ring protruding outward is provided at the upper end of the suspension cylinder 2, which can be pressed by the pressing ring 67. The suspension cylinder 2 is provided to separate the bacterial liquid on the inoculation tool 3 from the sterilization module 11, avoiding contamination caused by the bacterial liquid dripping onto the sterilization module 11, and the suspension cylinder 2 can be taken out separately for cleaning, effectively avoiding water ingress into the equipment; with the help of the pressing ring 67 and the T-shaped positioning cylinder 12, the suspension cylinder 2 can be fixed, effectively avoiding collisions between the suspension cylinders 2 due to reasons such as the movement of the moving body 1, etc.

[0042] During operation, power is turned on, and bacteria are killed by the sterilization module 11. After the first sterilization is completed, the inoculation mechanism is driven upward by the lifting mechanism. After the movable rod 73 contacts the fixed pressing member 5, the movable rod 73 moves downward under pressure, causing the connecting spring 72 to be in a stretched state. The movable rod 73 drives the mating cylinder 76 to move downward, and the mating cylinder 76 pushes the rigid contact portion 792. The rigid contact portion 792 squeezes the elastic portion 791 and drives the insertion column 74 to disengage from the insertion hole 81, completing the unlocking operation of the inoculation tool 3. After that, the experimenter can use the inoculation tool 3 for bacterial inoculation. After one inoculation is completed, the T-shaped movable member 8 is inserted into the sliding through hole 63. Then, the inoculation mechanism is driven downward by the lifting mechanism. The movable rod 73 returns to its original position under the drive of the elastic force of the connecting spring 72, and the elastic portion 791 expands, causing the rigid contact portion 792 to drive the insertion column 74 to insert into the insertion hole 81, completing the fixation of the inoculation tool 3. Then, the inoculation tool 3 is driven downward by the lifting mechanism so that the inoculation tool 3 extends into the suspension cylinder 2 for sterilization. After the inoculation tool 3 is fixed, the operator can activate another lifting mechanism to take another inoculation tool 3 away from the corresponding suspension cylinder 2 and unlock another inoculation tool 3 to continue the inoculation operation.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
