Description

Technical Field

[0001] This utility model relates to the field of compound bacterial culture technology, specifically to a compound bacterial mixing incubator. Background Technology

[0002] Compound microbial strains are microbial preparations made from two or more non-antagonistic microbial strains. These microbial agents generally have excellent characteristics such as complete variety, reasonable compatibility, strong functionality, and high economic benefits. They can improve immunity, disease resistance, promote growth, and purify water quality by stimulating the body's immune system, regulating the body's microecological balance, antagonizing pathogenic microorganisms, and degrading organic waste in the breeding process. They are a type of green product with great development potential.

[0003] During the mixed culture of multiple microorganisms, it is necessary to observe the growth status of the microorganisms in real time to adjust the culture parameters, and to regularly sample and detect the activity and metabolites of the microorganisms. Currently, the observation windows of most mixed microorganism incubators are single-layered glass structures. When the humid and warm air inside the incubator comes into contact with the low-temperature external environment, fog easily forms on the inside of the glass, obstructing the view. This necessitates frequent shutdowns for wiping, and frequent opening and closing of the incubator not only affects the continuity of the culture but may also disrupt the sterile environment inside the incubator. Therefore, improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a compound bacterial culture box to solve the above problems.

[0005] The purpose of this utility model is achieved as follows: A compound bacterial culture box includes a box body, an observation window on the side wall of the box body, a transparent heating film attached to the inner side of the observation window, a temperature controller on the outer side of the box body, the transparent heating film being electrically connected to the temperature controller, a rotating shaft rotatably connected to the box body, the end of the rotating shaft penetrating the box body and connected to a connecting plate, a flexible scraper on the side wall of the connecting plate, and the flexible scraper being attached to the transparent heating film.

[0006] Preferably, the transparent heating film is an indium tin oxide transparent conductive film with a thickness of 50-100 μm.

[0007] Preferably, a knob is fixedly connected to one end of the rotating shaft located outside the housing.

[0008] Preferably, the flexible scraper includes a scraper body, and the sides of the scraper body are provided with a first scraping blade and a second scraping blade in a stepped manner. The first scraping blade is located above the second scraping blade, and a guide groove is provided between the first scraping blade and the second scraping blade.

[0009] Preferably, there are two guide grooves arranged at an angle and symmetrically, and the intersection of the two guide grooves is located directly below the central axis of the first scraper.

[0010] This utility model has the following beneficial effects:

[0011] 1. This composite microbial incubator uses a temperature controller to control the heating of a transparent heating film, raising the surface temperature of the observation window. This prevents condensation of humid air from forming fog when it comes into contact with the observation window. By rotating the shaft, the connecting plate rotates synchronously. A flexible scraper on the connecting plate slides on the surface of the transparent heating film, scraping away any residual water vapor or dirt. The heating film prevents fog condensation, and the use of the flexible scraper reduces the problem of blurred observation window. This eliminates the need for frequent shutdowns for wiping, avoiding damage to the sterile environment inside the incubator or affecting culture parameters such as temperature and humidity caused by frequent opening and wiping of the observation window.

[0012] 2. The flexible scraper includes a scraper body. The sides of the scraper body are arranged in a stepped manner with a first scraping blade and a second scraping blade. The first scraping blade is located above the second scraping blade. A guide groove is provided between the first scraping blade and the second scraping blade. The first scraping blade first contacts the surface of the heating film and scrapes off larger water droplets or stains. The second scraping blade then further scrapes off the residual droplets, forming a double-layer cleaning effect. The guide groove is located between the two scraping blades and is used to guide the scraped liquid to flow down the groove, avoiding the liquid from accumulating on the scraping blades or flowing back to the cleaning area, thus maintaining a clear field of vision.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0020] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0021] Example 1:

[0022] A mixed bacterial culture chamber includes a chamber body 1. The side wall of the chamber body 1 is provided with an observation window 2. A transparent heating film 3 is attached to the inner side of the observation window 2. A temperature controller 4 is provided on the outer side of the chamber body 1. The transparent heating film 3 is electrically connected to the temperature controller 4. A rotating shaft 5 is rotatably connected to the chamber body 1. The end of the rotating shaft 5 passes through the chamber body 1 and is connected to a connecting plate 6. A double fluororubber sealing ring is provided at the point where the rotating shaft 5 passes through the chamber body 1, and a sealing groove is provided to ensure that the sterility level inside the chamber reaches the ISO 5 standard. A flexible scraper 7 is provided on the side wall of the connecting plate 6, and the flexible scraper 7 is attached to the transparent heating film 3.

[0023] This incubator uses a temperature controller 4 to control the transparent heating film 3 to generate heat, raising the temperature of the inner surface of the observation window 2. This prevents the humid air inside the incubator from condensing into fog when it comes into contact with the observation window 2. By rotating the shaft 5, the connecting plate 6 is driven to rotate synchronously. The flexible scraper 7 on the connecting plate 6 slides on the surface of the transparent heating film 3, scraping away any residual water mist or stains. The heating film prevents fog from condensing, and the use of the flexible scraper 7 reduces the problem of blurring in the observation window 2. This eliminates the need for frequent shutdowns for wiping, avoiding damage to the sterile environment inside the incubator or affecting culture parameters such as temperature and humidity due to frequent opening and wiping of the observation window 2.

[0024] In this embodiment, the transparent heating film 3 is an indium tin oxide transparent conductive film with a thickness of 50-100 μm. Indium tin oxide has good transparency and conductivity, and can heat up evenly after being energized. The thickness is controlled at 50-100 μm, which can ensure the mechanical strength and durability of the heating film, and avoid the decrease in light transmittance or uneven heating caused by excessive thickness. At the same time, indium tin oxide has good chemical stability. It is an inert metal oxide, insoluble in water at room temperature, and will not react chemically with pure water mist. It will not directly cause short circuits in the film layer or a sudden drop in conductivity. Only when a large amount of electrolyte, such as nutrient salt residues in the incubator or microbial metabolites, is mixed in the water mist, local conductivity fluctuations may occur. However, in the clean environment of the composite bacteria incubator, the content of such impurities is extremely low, so there is no need to consider the impact too much.

[0025] It should be noted that the temperature controller 4 monitors the surface temperature of the transparent heating film 3 in real time and converts the resistance or voltage signal into a digital temperature value, which is then transmitted to the microprocessor of the temperature controller 4. The controller compares the measured temperature with a preset temperature, such as 40℃, and calculates the deviation. If the measured temperature is lower than the preset value, heating is started; if it is higher than the preset value, heating is stopped or the heating power is reduced. A safe 24V power supply is used, with a power density of 0.5-1W / cm³. 2 The time required to heat to 40℃ is ≤5 minutes. The technical means of the temperature controller 4 is a common existing technology, so it will not be described in detail here.

[0026] In this embodiment, a knob 8 is fixedly connected to one end of the rotating shaft 5 located outside the housing 1. The operator can manually rotate the knob 8 to drive the rotating shaft 5 to rotate, thereby driving the connecting plate 6 and the flexible scraper 7 inside the housing 1 to rotate synchronously, so as to achieve scraping and cleaning of the surface of the transparent heating film 3.

[0027] In this embodiment, the flexible scraper 7 includes a scraper body 71. The scraper body 71 has a first scraping blade 72 and a second scraping blade 73 arranged in a stepped parallel arrangement on its side. The scraper body 71 and the two scraping blades are made of food-grade silicone. The first scraping blade 72 is located above the second scraping blade 73. A guide groove 74 is provided between the first scraping blade 72 and the second scraping blade 73. The first scraping blade 72 first contacts the surface of the heating film and scrapes off larger water droplets or stains. The second scraping blade 73 then further scrapes off the residual droplets, forming a double-layer cleaning effect. The guide groove 74 is located between the two scraping blades and is used to guide the scraped liquid down the groove to avoid the liquid accumulating on the scraping blades or flowing back to the cleaning area, thus maintaining a clear field of vision.

[0028] In this embodiment, there are two guide channels 74 arranged in an inclined and symmetrical manner. The intersection of the two guide channels 74 is located directly below the central axis of the first scraper 72. The vertical distance between the intersection of the two channels and the central axis of the first scraper 72 is 2mm. The symmetrically inclined guide channels 74 can concentrate and guide the liquid scraped off from both sides to the area below the central axis, so that the liquid flows down along the edge of the observation window 2, avoiding diffusion to both sides and preventing liquid accumulation on one side.

[0029] The working principle of this utility model is as follows: The compound bacterial culture box includes a box body 1. An observation window 2 is provided on the side wall of the box body 1. A transparent heating film 3 is attached to the inner surface of the observation window 2. A temperature controller 4 is provided on the outer side of the box body 1. The transparent heating film 3 is electrically connected to the temperature controller 4. A rotating shaft 5 is rotatably connected to the box body 1. The end of the rotating shaft 5 passes through the box body 1 and is connected to a connecting plate 6. A flexible scraper 7 is provided on the side wall of the connecting plate 6. The flexible scraper 7 is attached to the transparent heating film 3. The temperature controller 4 controls the transparent heating film 3 to be energized and heated, increasing the temperature of the inner surface of the observation window 2. This prevents the humid air inside the box from condensing into mist when it comes into contact with the observation window 2. By rotating the rotating shaft 5, the connecting plate 6 is driven to rotate synchronously. The flexible scraper 7 on the connecting plate 6 slides on the surface of the transparent heating film 3, scraping away any residual water mist. To prevent condensation of water or dirt, the heating film prevents fogging. Combined with the flexible scraper 7, it reduces blurring of the observation window 2, eliminating the need for frequent shutdowns for wiping. This avoids disrupting the sterile environment inside the chamber or affecting culture parameters such as temperature and humidity due to frequent opening and wiping of the observation window 2. The flexible scraper 7 includes a scraper body 71. The sides of the scraper body 71 are arranged in a stepped, parallel manner with a first scraper blade 72 and a second scraper blade 73. The first scraper blade 72 is located above the second scraper blade 73. A guide groove 74 is provided between the first scraper blade 72 and the second scraper blade 73. The first scraper blade 72 first contacts the heating film surface, scraping away larger water droplets or dirt. The second scraper blade 73 then further scrapes away residual droplets, forming a double-layer cleaning effect. The guide groove 74 is located between the two scraper blades and is used to guide the scraped liquid down the groove, preventing liquid from accumulating on the scraper blades or flowing back into the cleaning area, maintaining a clear field of vision.

[0030] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be divided into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
