Description

Technical Field

[0001] This utility model relates to the field of medical experimental technology, specifically to a microbial constant temperature incubator. Background Technology

[0002] Microbial incubators are widely used in research fields such as pharmaceutical microbiology, food microbiology, agricultural microbiology, and medical microbiology. They have become one of the commonly used instruments in laboratories in these fields. The principle behind them is to simulate the growth environment of microorganisms in vivo within the incubator to culture microorganisms in vitro.

[0003] However, existing microbial culture devices, such as the microbial high-efficiency culture box disclosed in patent publication number CN214571966U, include a box body, a top cover, a culture tray, a lifting component, and a temperature control component. The top cover is fastened to the upper end of the box body, and the temperature control component is installed in the internal cavity of the box body. Lifting components are provided at the four corners of the temperature control component. The box body includes a water inlet, a water outlet, and pipes. A water inlet is opened on the front side wall of the box body, and a water outlet is opened on the rear side wall. Pipes are connected to both the water inlet and the water outlet.

[0004] To address the inconvenience of biological cultivation, this solution employs a cultivation tray with multiple cultivation chambers for microbial cultivation. Before cultivation, a lifting component moves the cultivation tray downwards until its height is below the water inlet and outlet. Cleaning agent, clean water, sterilizing liquid, and disinfectant are then sequentially introduced into the tank through the water inlet. However, the use of water can easily generate microorganisms and bacteria, requiring sterilizing and disinfecting liquids to inhibit bacterial growth, which significantly increases costs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention aims to provide a microbial constant temperature incubator. This solution utilizes air filtration, temperature regulation via heating, and humidity regulation via humidification to prevent uneven temperature and humidity from affecting the growth and reproduction of microorganisms. Furthermore, the filter plate design prevents dust from entering, thus reducing the possibility of contamination.

[0006] This utility model is achieved through the following technical solution:

[0007] A microbial constant temperature incubator, comprising:

[0008] A cabinet assembly, comprising a cabinet body, a temperature control mechanism, and a humidifier;

[0009] The microbial culture dish fixing mechanism is located in the internal cavity of the box-shaped body; the humidifier is used to humidify the internal cavity;

[0010] The constant temperature mechanism includes an outer shell located on one side of the box-shaped body, the outer shell having a cavity inside, the cavity being connected to the internal chamber of the box-shaped body on the side near the box-shaped body, and a heating component being provided at the connection point;

[0011] The cavity is equipped with a suction component;

[0012] The cavity is open on the other side, and a filter assembly is provided at the opening.

[0013] Compared to existing technologies where water use easily breeds microorganisms and bacteria, requiring sterilization and disinfection solutions for inhibition, leading to significantly increased costs, this invention provides a microbial constant temperature incubator. This solution utilizes air filtration, temperature regulation via heating, and humidity regulation via humidification to prevent uneven temperature and humidity from affecting microbial growth and reproduction. Furthermore, the filter plate prevents dust from entering, reducing the possibility of contamination. Specifically, the solution includes a box-shaped body, a constant temperature mechanism, and humidifiers. The internal chamber of the box-shaped body houses a microbial culture dish fixing mechanism for securing multiple culture dishes. Humidifiers are installed on both sides of the microbial culture dish fixing mechanism, distributed within the box-shaped body for uniform humidification. The temperature control mechanism includes an outer shell located outside the box-shaped main body. Its internal cavity serves as a ventilation channel, with a filter assembly at the inlet to filter impurities from the air. An air intake assembly, such as a fan, is installed within the ventilation channel to supply gas into the box-shaped main body. A heating assembly, located at the outlet connecting the ventilation channel and the internal cavity of the box-shaped main body, heats the intake air to control the internal temperature. Therefore, this solution, by controlling the internal temperature and humidity and filtering the gas, effectively prevents uneven temperature and humidity from affecting the growth and reproduction of microorganisms and prevents dust from entering, thus reducing the possibility of contamination.

[0014] To further optimize the system and facilitate the disassembly and assembly of the filter components for cleaning or replacement, the outer casing has an opening on the side away from the box-shaped body, and the outer casing has a slot at the opening.

[0015] The filter assembly includes a filter plate that can be inserted into the slot and is used to close the opening. The slot may be located at the top of the housing near the opening, and its opening length is greater than its width, to facilitate closing the opening and allow air to enter only through the filter plate.

[0016] To further optimize the system and achieve dual filtration, the filter plate includes a plate body in the shape of a frame. An inner filter screen and an outer filter screen are arranged sequentially from the inside to the outside in the middle of the plate body. The pore size of the inner filter screen is smaller than that of the outer filter screen.

[0017] To further optimize the filtration effect, a glass fiber membrane is provided between the inner filter and the outer filter.

[0018] To further optimize the design, and to facilitate the insertion of the filter plate and seal the sliding position to prevent dust from entering through gaps, the plate body has raised guide strips on both sides, and the slot has matching guide grooves on both sides.

[0019] A rubber gasket for sealing is provided between the guide slide and the side wall of the guide groove.

[0020] To further optimize the system, a handle is provided on the top of the filter plate for easy removal.

The output shaft of the rotary motor has a gear one, and several gears two mesh with the gear one in the circumferential direction.

[0022] The cavity has several ventilation holes on the side near the box-shaped body, and each ventilation hole is rotatably connected to a fan blade;

[0023] Each of the gears is directly opposite a fan blade and coaxially connected to the fan blade. Several gears are rotatably connected to the inner wall of the cavity, allowing them to rotate freely around their axis.

[0024] To further optimize the process and achieve uniform heating and distribution of air, a support plate and an exhaust plate are provided on the side of the internal chamber of the housing assembly near the outer shell. The support plate is located between the exhaust plate and the side wall of the housing assembly.

[0025] The support plate has several connecting holes that communicate with the outlet of the suction component; the heating component is located between the support plate and the exhaust plate and is used to heat the gas passing through the connecting holes. In this design, a gap is formed between the support plate and the inner side of the housing component, allowing the evenly distributed connecting holes on the support plate to disperse air into the heating component, thereby achieving uniform heating and improving the gas heating efficiency; while the exhaust plate can evenly disperse the heated gas into the housing component.

[0026] To further optimize the microbial culture dish fixing mechanism, in order to facilitate the spaced placement of different groups of culture dishes through several circumferentially distributed movable plates, and to enable the rapid placement and removal of culture dishes within the same group, the microbial culture dish fixing mechanism includes a driving component and a fixing component fixed in the internal cavity of the box-shaped body.

[0027] The fixed component includes a turntable, and the driving component is used to drive the turntable to rotate about its own axis.

[0028] The upper side of the turntable is evenly distributed with several movable plates, and the movable plates have several placement slots for placing petri dishes; the movable plates are movably connected to the turntable and can move away from or towards the axis of the turntable.

[0029] To further optimize the system and facilitate the placement of more culture dishes, the driving component is equipped with a drive motor, and the shaft of the driving component is vertically oriented upwards.

[0030] The drive shaft has several turntables coaxially mounted on it along its length.

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0043] Example 1:

[0044] This embodiment 1 provides a microbial constant temperature incubator, such as Figures 2-4 As shown, it includes:

[0045] Box assembly 1, which includes a box-shaped body 11, a constant temperature mechanism 2 and a humidifier 14;

[0046] The box-shaped body 11 has a microbial culture dish fixing mechanism in its internal chamber; the humidifier 14 is used to humidify the internal chamber.

[0047] The constant temperature mechanism 2 includes an outer shell 201 located on one side of the box-shaped body 11. The outer shell 201 has a cavity inside. The cavity is connected to the internal chamber of the box-shaped body 11 on the side close to the box-shaped body 11. A heating component 212 is provided at the connection position.

[0048] The cavity is equipped with a suction component;

[0049] The cavity is open on the other side, and a filter assembly is provided at the opening.

[0050] Compared to existing technologies where water use easily breeds microorganisms and bacteria, requiring sterilization and disinfection solutions for inhibition, leading to significantly increased costs, this invention provides a microbial constant temperature incubator. This solution utilizes air filtration, temperature regulation via heating, and humidity regulation via humidification to prevent uneven temperature and humidity from affecting microbial growth and reproduction. Furthermore, the filter plate 205 prevents dust from entering, reducing the possibility of contamination. Specifically, the solution includes a box-shaped body 11, a constant temperature mechanism 2, and humidifiers 14. The internal chamber of the box-shaped body 11 houses a microbial culture dish fixing mechanism to secure several culture dishes. A set of humidifiers 14 is installed on both sides of the microbial culture dish fixing mechanism, distributed within the box-shaped body 11 for uniform humidification. The temperature control mechanism 2 includes an outer shell 201 located outside the box-shaped body 11. Its internal cavity serves as a ventilation channel, with a filter assembly at the inlet to filter impurities from the air. An air intake assembly, such as a fan, is installed within the ventilation channel to supply gas into the box-shaped body 11. A heating assembly 212 is located at the outlet where the ventilation channel connects to the internal cavity of the box-shaped body 11, heating the intake air to control the internal temperature. Therefore, by controlling the internal temperature and humidity and filtering the gas, the above solution effectively avoids uneven temperature and humidity that could affect the growth and reproduction of microorganisms, and prevents dust from entering, thus reducing the possibility of contamination.

[0051] In this embodiment, to facilitate the disassembly and assembly of the filter assembly for cleaning or replacement, the outer shell 201 has an opening on the side away from the box-shaped body 11, and the outer shell 201 has a slot 203 at the opening.

[0052] The filter assembly includes a filter plate 205, which can be inserted into the slot 203 and is used to close the opening. The slot 203 can be located on the top of the housing 201 near the opening, and the opening length is greater than the opening width, so as to close the opening and allow air to enter only through the filter plate 205.

[0053] In this embodiment, to achieve dual filtration, the filter plate 205 includes a plate body 2051, which is frame-shaped. An inner filter screen 2054 and an outer filter screen 2056 are arranged sequentially from the inside to the outside in the middle of the plate body 2051. The pore size of the inner filter screen 2054 is smaller than that of the outer filter screen 2056.

[0054] In this embodiment, to improve the filtration effect, a glass fiber membrane 2055 is also provided between the inner filter screen 2054 and the outer filter screen 2056.

[0055] In this embodiment, in order to facilitate the insertion of the filter plate 205 and seal the sliding position to prevent dust from entering through the gap, the plate body 2051 has raised guide strips on both sides, and the slot 203 has matching guide grooves on both sides.

[0056] A rubber gasket 204 for sealing is provided between the guide slide and the side wall of the guide groove.

[0057] In this embodiment, a handle 2052 is provided on the top of the filter plate 205 to facilitate pulling out the filter plate 205.

[0058] In this embodiment, as a specific structure of a suction component, the suction component includes a rotary motor 207, which is fixed in the cavity by a support platform 206. The output shaft of the rotary motor 207 is equipped with a gear 208, and a plurality of gears 209 mesh with the gear 208 in the circumferential direction.

[0059] The cavity has several ventilation holes on the side near the box-shaped body 11, and each ventilation hole is rotatably connected to a fan blade 210.

[0060] Each of the gears 209 is directly opposite a fan blade 210 and is coaxially connected to the fan blade 210. Several gears 209 are rotatably connected to the inner wall of the cavity, allowing them to rotate freely around their axis.

[0061] In this embodiment, in order to achieve uniform heating and uniform distribution of air, a support plate 211 and an exhaust plate 213 are provided on the side of the internal cavity of the housing assembly 1 near the outer shell 201. The support plate 211 is located between the exhaust plate 213 and the side wall of the housing assembly 1.

[0062] The support plate 211 has several connecting holes that communicate with the outlet of the suction component; the heating component 212 is located between the support plate 211 and the exhaust plate 213, and is used to heat the gas passing through the connecting holes. In this design, a gap is formed between the support plate 211 and the inner side of the housing component 1, allowing the several evenly distributed connecting holes on the support plate 211 to disperse air into the heating component 212, thereby achieving uniform heating and improving the gas heating efficiency; while the exhaust plate 213 can evenly disperse the heated gas into the housing component 1.

[0063] Example 2:

[0064] This embodiment 2 is a further optimization based on embodiment 1, such as... Figure 1 and Figure 5 As shown, a specific embodiment of a microbial culture dish fixation mechanism is provided; including:

[0065] Drive component 214;

[0066] Fixing component 3, the fixing component 3 includes a turntable 301, and the driving component 214 is used to drive the turntable 301 to rotate around its own axis;

[0067] The upper side of the turntable 301 is evenly distributed with several movable plates 312, and the movable plates 312 are provided with several placement slots 306 for placing petri dishes; the movable plates 312 are movably connected to the turntable 301 and can move away from or towards the axis of the turntable 301.

[0068] Compared to existing technologies, when several different groups of culture dishes are placed, the lack of a dedicated spacing device makes it difficult to quickly distinguish between them when removing them from the turntable 301, and also makes it difficult to quickly remove culture dishes from the same group. This utility model provides a microbial culture dish fixing mechanism and a microbial incubator. Using this solution, different groups of culture dishes can be placed at intervals through several circumferentially distributed movable plates 312, and the culture dishes in the same group can be quickly placed in and removed. The specific design includes a horizontally placed turntable 301, with a driving component 214 that rotates the turntable 301 around its own axis, thereby moving several culture dishes placed on the turntable 301 within the culture chamber. Several movable plates 312 are evenly distributed circumferentially on the side of the turntable 301. Preferably, the movable plates 312 are arranged radially along the rotation axis 215, and each movable plate 312 has several placement slots 306. Culture dishes in the same group can be placed on the same movable plate 312. Thus, by using the spaced-apart movable plates 312, different groups of culture dishes can be placed separately, achieving the purpose of differentiation. Furthermore, the movable plates 312 can move away from or towards the axis of the turntable 301. This allows for quick placement and removal of culture dishes when it is necessary to put in or take out the same group of culture dishes, simply by pulling out the movable plate 312, enabling rapid placement and removal without having to insert them into the culture chamber.

[0069] In this embodiment, as a specific method of movable connection, the turntable 301 is evenly distributed with a plurality of movable grooves 307 in the circumferential direction. The movable grooves 307 are arranged radially along the turntable 301 and pass through the end of the turntable 301. The movable plate 312 is slidably connected to the movable grooves 307 and slides radially along the turntable 301, so that the movable plate 312 can partially slide out of the movable grooves 307.

[0070] In this embodiment, to facilitate the guiding and limiting of the sliding of the movable plate 312, both sides of the movable groove 307 are provided with sliding grooves 304 arranged along their own length direction; both sides of the movable plate 312 are provided with slide rails 305 adapted to the sliding grooves 304. Both the sliding grooves 304 and the slide rails 305 can be adapted to each other in a dovetail shape.

[0071] In this embodiment, to prevent the movable plate 312 from slipping off the turntable 301, each of the movable slots 307 has a movable block 311 on the upper side of the turntable 301; the movable plate 312 has a stop block 315 on the side wall of the end near the axis of the turntable 301.

[0072] The movable block 311 is located within the path of the stop block 315 moving away from the axis of the turntable 301;

[0073] The movable block 311 has an embedding groove on the upper side of the turntable 301 at its bottom. The movable block 311 is connected to the bottom of the embedding groove by a first spring. The movable block 311 is embedded in or extends out of the embedding groove by the first spring. In this design, the movable block 311 is positioned near the outer end of the movable plate 312, and the stop block 315 is a protrusion on the inner side wall of the movable plate 312. Therefore, when the movable plate 312 slides outward and is about to slide out of the turntable 301, the movable block 311 can abut against the stop block 315, preventing the movable plate 312 from sliding out further. In addition, when it is necessary to remove the movable plate 312 from the turntable 301, the movable block 311 can be pressed into the embedding groove to remove the movable plate 312.

[0074] In this embodiment, to facilitate the pulling out of the movable plate 312, the end of the movable plate 312 away from the axis of the turntable 301 is equipped with a pull ring 308.

[0075] In this embodiment, after the movable plate 312 is pushed in, in order to prevent the movable plate 312 from sliding on its own, the pull ring 308 and the end of the movable plate 312 are rotatably connected and can rotate along its own axis; the pull ring 308 has a locking block 309 located outside the turntable 301 on its side wall;

[0076] The turntable 301 has a plurality of limiting blocks 310 evenly distributed on its circumferential end, and each limiting block 310 corresponds to a movable plate 312; the limiting block 310 has a slot 2053 on the side facing the pull ring 308.

[0077] The rotation of the pull ring 308 is used to drive the locking block 309 to screw into or out of the locking groove 2053, thereby limiting the displacement of the movable plate 312. In this design, the pull ring 308 is preferably perpendicular to the end of the movable plate 312. A limiting block 310 is provided on the end of the turntable 301 below the pull ring 308. The limiting block 310 can be an L-shaped plate, with one side connected to the end of the turntable 301 and the other side facing the pull ring 308. In this way, a locking groove 2053 can be formed at the L-shaped limiting block 310. By rotating the pull ring 308, the locking block 309 on the pull ring 308 can be screwed into the locking groove 2053, thereby limiting the displacement of the movable plate 312 in the radial direction of the rotating shaft 215.

[0078] In this embodiment, to clamp and fix the culture dish, the inner side of the placement groove 306 has two clamping plates 314 that can clamp towards each other. The back of the clamping plates 314 is connected to the placement groove 306 via a second spring 313. The top of the clamping plates 314 has a guide surface that slopes downward toward the axial direction of the placement groove 306. In this design, the two clamping plates 314 are in opposite arc shapes and are located on both sides inside the placement groove 306. They can be partially slidably embedded, allowing the two clamping plates 314 to move closer or further apart, and they have a certain clamping force under the action of the second spring 313. When the culture dish is placed in, it enters through the guide surface at the top of the clamping plates 314 and presses the two clamping plates 314, so that the two clamping plates can clamp the side wall of the culture dish relative to each other.

[0079] In this embodiment, to facilitate the placement of more groups of culture dishes, the driving component 214 is a driving motor, and the rotating shaft 215 of the driving component 214 is vertically arranged facing upward; the rotating shaft 215 of the driving component 214 is coaxially fitted with several turntables 301 along its own length direction.

[0080] In this embodiment, to facilitate the adjustment of the height of the turntable 301, the turntable 301 is sleeved on the rotating shaft 215 via a sleeve 302; the sleeve 302 and the rotating shaft 215 are slidably connected and can move along the axis of the rotating shaft 215; the sleeve 302 is also equipped with a clamp 303, which is used to fix the sleeve 302 and the rotating shaft 215 via the clamp 303. In this solution, the connection between the sleeve 302 and the rotating shaft 215 can be achieved by opening a vertical sliding groove on the rotating shaft 215, wherein the clamp 303 can be a threaded part, the clamp 303 and the sleeve 302 are threadedly connected, and screwed into the sliding groove, thereby maintaining only the vertical sliding of the turntable 301 and the sleeve 302. When the adjustment is in place, tightening the clamp 303 against the inner side of the sliding groove can achieve fixation.

[0081] Working principle:

[0082] like Figure 1-5As shown, by pulling handle 13 to open the box door 12, the petri dish is placed on the fixing assembly 3, and the filter plate 205 is aligned with the slot 203, so that the slots 2053 on both sides of the plate 2051 are inserted into the slot 203. The rubber pad 204 can prevent dust from entering through the gaps. When the rotary motor 207 on the surface of the support platform 206 drives the gear one 208 to rotate, the gear two 209 drives the fan blade 210 to rotate. Air enters through the outer filter screen 2056, is filtered by the glass fiber membrane 2055, and then passes through the inner filter screen 2054, which is finer than the outer filter screen 2056. At this time, the heating assembly 212 on the surface of the support plate 211 is heated, and the air passes through the surface of the support plate 211. After passing through the heating component 212, the heated air enters the interior of the chamber body 11 via the exhaust plate 213. At this time, the driving component 214 drives the rotating shaft 215, causing the fixing component 3 to rotate. This ensures that the culture dish on the surface of the fixing component 3 is heated evenly and maintained at a certain temperature. Simultaneously, the humidifiers 14 on both sides humidify the interior of the chamber body 11, maintaining the internal temperature and humidity. This device prevents uneven temperature and humidity from affecting the growth and reproduction of microorganisms. The filter plate 205 prevents dust from entering and reduces the possibility of contamination. When replacement or cleaning is needed, pulling the handle 2052 allows the filter plate 205 to be removed for replacement or cleaning. The outer casing 20... The top cover 202 of the thermostat mechanism 2 can block dust and facilitate disassembly for internal maintenance. Simultaneously, rotating the pull ring 308 disengages the locking block 309 from the limiting block 310. Pulling the pull ring 308 causes the movable plate 312 to slide on the surface of the movable groove 307, while the slide rail 305 slides inside the slide groove 304, moving the movable plate 312 outwards until the stop block 315 contacts the movable block 311. The culture dish is then placed on the placement groove 306. When the bottom of the placement groove 306 contacts the clamping plate 314, the clamping plate 314 compresses the second spring 313. After the culture dish is fully placed, the second spring 313 drives the clamping plate 314 to hold the culture dish in place. The movable plate 312 is pushed inward to reset. At this time, rotating the pull ring 308 causes the locking block 309 to engage with the limiting block 310 to complete the fixation. This device can clamp and fix the culture dish, and also creates a gap between different groups of culture dishes for easy identification. At the same time, by turning the clamp 303, the sleeve 302 drives the turntable 301 to adjust the height up and down. After the height adjustment is completed, turning the clamp 303 fixes it. When it is necessary to clean the movable plate 312, pull out the movable plate 312 and press the movable block 311. The bottom end of the movable block 311 is equipped with a spring, which causes the movable block 311 to retract into the turntable 301, so that the movable plate 312 can be taken out for cleaning, avoiding the growth of microorganisms. This improves the adaptability of the device.

It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
