Description

Technical Field

[0001] This utility model specifically relates to the field of experimental auxiliary equipment technology, and more specifically to a device for rapidly dissolving and mixing dry powder culture medium. Background Technology

[0002] A rapid dissolving and mixing device for dry powder culture media is a device used to accelerate the dissolution and uniform mixing of dry powder culture media. Dry powder culture media contain organic components such as peptone and yeast extract, as well as high molecular weight substances such as agar. When added directly to water, they are prone to forming "encapsulated clumps". Manual stirring requires repeated breaking up, which is time-consuming and laborious. In order to ensure that the culture media achieves the requirements of high efficiency, uniformity, sterility and stability in the dissolution and mixing process, a magnetic stirring and mixing device is generally used to rapidly dissolve the dry powder culture media. The magnetic field generated by the magnetic stirring and mixing drive unit in the magnetic stirring and mixing device can rotate the disposable magnetic stirring paddle coupled with the non-detachable ceramic bearing, thereby efficiently dispersing and mixing the powder.

[0003] However, in practice, it has been noted that current magnetic stirring mixing devices typically place the culture cup directly on the device's worktable and then use the rotational force of the magnetic core to create a vortex within the dry powder culture medium solution. However, the rotation of the solution generates centrifugal force, which can easily cause the culture cup to shift or tip over, resulting in solution spillage, directly interrupting the mixing process, or even contaminating the experimental environment or damaging device components. Utility Model Content

[0004] The purpose of this invention is to provide a device for rapidly dissolving and mixing dry powder culture media. By cooperating with a micro-vacuum pump through a negative pressure adsorption hole on the worktable, the device adsorbs the culture dish or culture cup placed on the worktable, ensuring the stability of the rotating magnetic core during rotation inside the culture dish or culture cup. This prevents the culture dish or culture cup from tipping over due to centrifugal force generated by the solution during rotation, thereby improving the stability of the mixing process. This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for rapidly dissolving and mixing dry powder culture medium includes a culture medium placement platform for placing culture cups, a support base below the culture medium placement platform, and an installation shell for the culture medium placement platform between the support base and the culture medium placement platform.

[0007] The culture medium placement platform has a workbench with a hollow groove at the bottom and negative pressure adsorption holes arranged in a ring array in the workbench that communicate with the hollow groove. The end of the negative pressure adsorption hole away from the hollow groove is connected to the top of the workbench.

[0008] As a further technical solution of this utility model, the interior of the support base is hollow, and a limiting ring is integrally provided on the bottom inner side of the support base. A micro drive motor is fixedly connected in the limiting ring, and a rotating disk is fixedly connected to the output shaft end of the micro drive motor. Both ends of the rotating disk are embedded with driving magnetic poles.

[0009] As a further technical solution of this utility model, the mounting shell includes a support plate fixed to the top of the support base, and one end of the support plate is integrally provided with a positioning protrusion, and the top of the positioning protrusion is inserted into the hollow groove.

[0010] A sealing sleeve is inserted between the positioning protrusion and the hollow groove, and the sealing sleeve is fixedly connected to the worktable, while the sealing sleeve fits tightly against the positioning protrusion.

[0011] As a further technical solution of this utility model, the bottom of the support plate is also provided with an inner recessed groove corresponding to the positioning protrusion, and the rotating disk is located inside the positioning protrusion. The inner side of the inner recessed groove is also provided with an air outlet pipe, which is located on one side of the rotating disk, and the top of the inner side of the air outlet pipe extends to the top of the positioning protrusion.

[0012] As a further technical solution of this utility model, a miniature vacuum pump is also provided below the support plate. The air inlet of the miniature vacuum pump is fixedly connected to a negative pressure pipe, and the other end of the negative pressure pipe is fixedly connected to an air outlet pipe.

[0013] The air inlet of the miniature vacuum pump is connected to the inside of the negative pressure pipe through a negative pressure pipe, and the miniature vacuum pump is fixedly connected to the support base.

[0014] As a further technical solution of this utility model, a rotating magnetic core is also provided above the worktable. The rotating magnetic core is arranged in a quadrangular shape, and the inner side of the rotating magnetic core is also wrapped with a traction magnet corresponding to the driving magnetic pole.

[0015] As a further technical solution of this utility model, rubber pads are fixedly connected in a rectangular array above the support plate, and the top of the rubber pads contacts the workbench. The end of the support plate away from the workbench is inclined, and a control module is fixedly connected below the support plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, a culture cup containing dry powder culture medium is first placed on top of a workbench. Then, by using a micro vacuum pump and a negative pressure pipeline, the air inside the hollow groove is extracted, reducing the air pressure inside the hollow groove. Since the culture cup completely covers the negative pressure adsorption hole, the negative air pressure inside the hollow groove will adsorb the culture cup on top of the workbench through the negative pressure adsorption hole, thus improving the stability of the culture cup on the workbench.

[0018] 2. In this invention, a rotating magnetic core is placed in a culture cup containing dry powder culture medium. Then, a micro drive motor is started. The output shaft of the micro drive motor drives the rotating disk to rotate. The driving magnetic poles at both ends of the rotating disk attract each other with the magnets inside the rotating magnetic core, causing the rotating magnetic core to rotate in the dry powder culture medium solution. This rapidly mixes the dry powder culture medium solution. Furthermore, during mixing, eddies are generated in the solution due to centrifugal force. Combined with the negative pressure adsorption of the culture medium placement platform, this improves the stability of the mixing process.

[0019] 3. In this utility model, a sealing sleeve is fixed inside the hollow groove, and the sealing sleeve seals the gap between the hollow groove and the positioning protrusion, thereby forming a gap between the hollow groove and the positioning protrusion. This gap, combined with the negative pressure adsorption hole, adsorbs the culture cup. In addition, rubber pads are provided around the positioning protrusion, which can not only support the worktable but also reduce the vibration of the worktable and further improve stability.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-7 This utility model provides a device for rapidly dissolving and mixing dry powder culture medium, including a culture medium placement platform 4 for placing culture cups, a support base 1 below the culture medium placement platform 4, and an installation shell 2 for the culture medium placement platform 4 between the support base 1 and the culture medium placement platform 4. Before use, the culture medium placement platform 4 is placed on the experimental table, and then the culture cup is placed on top of the culture medium placement platform 4.

[0031] The culture medium placement platform 4 has a workbench 41. The bottom of the workbench 41 has a hollow groove 42, and the workbench 41 has negative pressure adsorption holes 44 arranged in a ring array that communicate with the hollow groove 42. The culture cup can be adsorbed onto the surface of the workbench 41 by the internal negative pressure adsorption mechanism, thereby improving the stability of the culture cup. The end of the negative pressure adsorption hole 44 away from the hollow groove 42 is connected to the top of the workbench 41.

[0032] By adopting the above technical solution, the culture cup containing dry powder culture medium is first placed above the workbench 41. Then, the air inside the hollow groove 42 is extracted to reduce the air pressure inside the hollow groove 42. Since the culture cup completely covers the negative pressure adsorption hole 44, the negative air pressure inside the hollow groove 42 will adsorb the culture cup above the workbench 41 through the negative pressure adsorption hole 44, thereby improving the stability of the culture cup above the workbench 41.

[0033] Furthermore, the interior of the support base 1 is hollow, and a limiting ring is integrally provided on the inner bottom of the support base 1. A micro drive motor 7 is fixedly connected in the limiting ring, and a rotating disk 8 is fixedly connected to the output shaft end of the micro drive motor 7. Both ends of the rotating disk 8 are embedded with driving magnetic poles 9.

[0034] Furthermore, both sides of the support base 1 are provided with heat dissipation holes 6 in a rectangular array, which allow airflow inside and outside the support base 1 to flow rapidly.

[0035] More specifically, the mounting housing 2 includes a support plate 21 fixed to the top of the support base 1, and one end of the support plate 21 is integrally provided with a positioning protrusion 22, and the top of the positioning protrusion 22 is inserted into the hollow groove 42.

[0036] Furthermore, a sealing sleeve 43 is inserted and fitted between the positioning protrusion 22 and the hollow groove 42, and the sealing sleeve 43 is fixedly connected to the worktable 41, while the sealing sleeve 43 is tightly fitted to the positioning protrusion 22.

[0037] Furthermore, the bottom of the support plate 21 is provided with an inner recess 25 corresponding to the positioning protrusion 22, and the rotating disk 8 is located inside the positioning protrusion 22. The inner side of the inner recess 25 is also provided with an air outlet 24, which is located on one side of the rotating disk 8, and the top of the inner side of the air outlet 24 extends to the top of the positioning protrusion 22.

[0038] More specifically, a miniature vacuum pump 27 is also provided below the support plate 21. The air inlet of the miniature vacuum pump 27 is fixedly connected to a negative pressure pipe 26, and the other end of the negative pressure pipe 26 is fixedly connected to an air outlet pipe 24.

[0039] The air inlet of the miniature vacuum pump 27 is connected to the inside of the negative pressure pipe 26 through the negative pressure pipe 26, and the miniature vacuum pump 27 is fixedly connected to the support base 1.

[0040] Furthermore, a rotating magnetic core 5 is provided above the workbench 41. The rotating magnetic core 5 is arranged in a quadrangular shape, and the inner side of the rotating magnetic core 5 is also wrapped with a traction magnet corresponding to the driving magnetic pole 9.

[0041] By adopting the above technical solution, the rotating magnetic core 5 is placed in a culture cup containing dry powder culture medium, and then the micro drive motor 7 is started. The output shaft of the micro drive motor 7 drives the rotating disk 8 to rotate. The driving magnetic poles 9 at both ends of the rotating disk 8 attract each other with the magnets inside the rotating magnetic core 5, so that the rotating magnetic core 5 rotates in the dry powder culture medium solution, thereby quickly mixing the dry powder culture medium solution. In addition, during the mixing process, eddies are generated in the solution due to centrifugal force. Combined with the negative pressure adsorption of the culture medium placement platform 4, the stability of the mixing process is improved.

[0042] Furthermore, rubber pads 23 are fixedly connected in a rectangular array above the support plate 21, and the top of the rubber pads 23 contacts the worktable 41. The end of the support plate 21 away from the worktable 41 is inclined, and a control module 3 is fixedly connected below the support plate 21.

[0043] Furthermore, the control module 3 includes a support plate 21 fixedly connected to the bottom of the circuit board 32, and a display screen 31 is also fixedly connected to the support plate 21. The end of the support plate 21 is also provided with a hole corresponding to the display screen 31, and the display screen 31 extends through the hole to the upper surface of the support plate 21.

[0044] By adopting the above technical solution, a sealing sleeve 43 is fixed inside the hollow groove 42, and the sealing sleeve 43 seals the gap between the hollow groove 42 and the positioning protrusion 22, thereby forming a gap between the hollow groove 42 and the positioning protrusion 22. This gap, combined with the negative pressure adsorption hole 44, adsorbs the culture cup. In addition, rubber pads 23 are provided around the positioning protrusion 22, which can not only support the worktable 41, but also reduce the vibration of the worktable 41 and further improve stability.

[0045] Furthermore, a speed adjustment knob 33, a switch button 34, and an indicator light 35 are also installed on the top of the support plate 21. At the same time, the surface of the support plate 21 is also provided with through holes corresponding to the speed adjustment knob 33, the switch button 34, and the indicator light 35. Moreover, the speed adjustment knob 33, the switch button 34, and the indicator light 35 extend through the through holes to the surface of the support plate 21.

[0046] The support plate 21 is powered by an external power source. The rotation speed adjustment knob 33 can adjust the rotation speed of the micro drive motor 7, thereby controlling the rotation speed of the drive magnetic pole 9, thus achieving variable speed mixing and improving the mixing effect.

[0047] Furthermore, when the positioning protrusion 22 is inserted into the inner side of the hollow groove 42, a sealed space is provided between the hollow groove 42 and the positioning protrusion 22. At this time, by pressing and holding one of the switch buttons 34, the micro vacuum pump 27 is started. The micro vacuum pump 27 extracts air from the sealed space through the cooperation of the negative pressure pipe 26 and the air outlet pipe 24. At this time, since the culture cup completely covers the negative pressure adsorption hole 44, a negative pressure is formed in the sealed space, and the bottom of the culture cup is adsorbed through the negative pressure adsorption hole 44.

[0048] After mixing the dry powder culture medium, press another switch button 34 to control the micro vacuum pump 27 to rotate in reverse, delivering air into the sealed space to counteract the adsorption force, and finally remove the culture cup from the workbench 41.

[0049] The working principle of this utility model is as follows: First, the rotating magnetic core 5 is placed in a culture cup containing a solution. Then, the culture cup is placed above the workbench 41, ensuring that the bottom of the culture cup completely covers the top of the negative pressure adsorption hole 44. An external power supply is then used to control the micro vacuum pump 27, which, through the cooperation of the negative pressure pipe 26 and the air outlet pipe 24, extracts air from the sealed space. Since the culture cup completely covers the negative pressure adsorption hole 44, a negative pressure is created within the sealed space, adsorbing the bottom of the culture cup through the negative pressure adsorption hole 44. Then, rotating the speed adjustment knob 33 adjusts the rotation speed of the micro drive motor 7. The output shaft of the micro drive motor 7 drives the rotating disk 8 to rotate. The driving magnetic poles 9 at both ends of the rotating disk 8 attract the magnets inside the rotating magnetic core 5, causing the rotating magnetic core 5 to rotate in the solution. Centrifugal force creates a vortex in the internal solution. A sampling spoon is then used to pour the dry powder culture medium into the solution, allowing it to dissolve quickly. The structure is simple, the operation is very convenient, and it effectively reduces manual labor intensity.
