TECHNICAL FIELD
[0001] The application relates to the technical field of incubators, in particular to an internal circulation humidification system of an incubator. BACKGROUND
[0002] In many fields such as biology, medicine and scientific research, incubators are widely used to provide stable and suitable environmental conditions for the cultivation of microorganisms, cells, tissues and the like. Among them, humidity as a key environmental parameter has an important influence on the growth, development and experimental results of the cultivation objects.
[0003] At present, most of the mainstream incubators use an external humidifier to provide atomized mist to the incubator in one direction. This humidification method has many drawbacks. On the one hand, the atomization in the incubator lacks a water-saving recycling mechanism. After the mist generated by the external humidifier is used in the incubator, the excess water directly flows to the sewage pipe in the form of condensation water and is discharged, causing a large waste of water resources. According to actual tests, the water consumption of an incubator using an external humidifier is as high as 5.5 liters in one conventional cultivation cycle, which not only increases the operational burden of the user to frequently add water, but also increases the use cost, especially in the context of increasingly precious water resources and large-scale experimental applications, this problem is even more prominent.
[0004] On the other hand, the humidification rate of the external humidifier is relatively low, and it cannot quickly and effectively raise the humidity in the incubator to the set level, thereby affecting the efficient development of the experimental process. At the same time, its humidification parameter stability is poor, and it is difficult to accurately maintain a constant humidity environment required for cultivation, and the fluctuation of humidity may adversely affect the growth state of the cultivation objects, resulting in errors or deviations in the experimental results, and reducing the reliability and repeatability of the experiment.
[0005] In addition, the external humidifier usually needs to occupy additional space for installation and placement, making the overall layout of the incubator not compact enough, and the integration with the main body of the incubator is not high, which further limits the placement and use flexibility of the incubator in a limited laboratory environment. In summary, the existing external humidifier has obvious defects in the application of the incubator, and there is an urgent need for a more efficient, water-saving and stable humidification system to meet the actual needs, which also provides an important practical background and technical improvement direction for the research and development of the present application. CONTENT OF THE INVENTION

[0016] Further, the pipe port of the out-mist pipeline in the culture cavity is located at 2 / 3 of the height of the culture cavity, and the pipe port of the in-mist pipeline in the culture cavity is located at 1 / 3 of the height of the culture cavity.
[0017] Further, the out-mist pipeline and the in-mist pipeline are embedded in the foamed thermal insulation layer of the box body.
[0018] Further, the base of the ultrasonic atomizer is connected with an external water storage tank through a water pump.
[0019] Further, the return air fan is a waterproof fan.
[0020] Further, the base of the ultrasonic atomizer is provided with a water receiving groove for receiving condensation outside the ultrasonic atomizer.
[0021] Compared with the existing mainstream culture box external humidifier, the present application has the following beneficial effects:
[0022] 1. Water-saving recycling: the end of the out-mist pipeline located in the culture cavity is provided with an upwardly inclined pipe port, so that the condensed water can return to the water storage space of the base at the bottom of the ultrasonic atomizer, realizing water resource recycling and changing the current situation of no water-saving circulation and serious water resource waste of the existing external humidifier.
[0023] 2. Efficient internal circulation humidification: The ultrasonic atomizer is matched with the out-atomization pipeline, the in-atomization pipeline and the return air fan at the end of the in-atomization pipeline to realize the internal circulation of the mist in the culture cavity.

[0035] As Figures 1-4 shown, the internal circulation humidification system of the present culture box aims to solve the problems of large water consumption and no water saving circulation of the existing mainstream culture box external humidifier 2, and realizes efficient, water-saving and stable humidification effect through a series of structural design and functional setting. The specific technical solutions of the present application are as follows:
[0036] Overall working principle: the ultrasonic atomizer 21 in the humidifier 2 pipeline component produces fine mist particles and large mist volume. The mist circulates in the sealed inner cavity (culture cavity 11) of the box body 1 under the action of the in-out atomization pipeline 3 and the auxiliary return air waterproof fan, realizing internal circulation humidification. Compared with the external humidifier 2, the water consumption is reduced from 5.5 liters to 1 liter, saving 80% of water, and the humidification rate is increased by 28%.
[0037] Among them, the basic principle of humidifier 2 is the prior art, and the water circulation function is added on this basis. It mainly includes upper cover 23, float ball valve 24, base 22, sealing pad, ultrasonic atomizer 21, float ball valve 24 baffle and upper cover sealing pad 25. The ultrasonic atomizer 21 is provided with an ultrasonic atomization sealing pad.
[0038] Mist outlet design: the end of the mist outlet pipeline 3 located in the culture cavity 11 is provided with an upwardly arranged inclined pipe opening 31 to realize the backflow of the condensed water of the inclined pipe opening 31 to the bottom of the ultrasonic atomizer 21, and the bottom of the ultrasonic atomizer 21 is provided with a water storage space. The inclined pipe opening 31 is slightly upward and forms an angle of 13°-15° with the horizontal line, so that the condensed water of the pipe opening can flow back to the bottom of the humidifier 2 and be reused for humidification.
[0039] Air return structure: the air return waterproof fan (air return fan 5) inhales air inward, the air return flow guide cover 6 is a four-side tapered neck type, with a taper of 120°, to reduce air resistance and ensure that effective air enters the pipe. The pipe opening of the mist outlet pipeline 3 in the culture cavity 11 is located at 2 / 3 of the height of the culture cavity 11, and the pipe opening of the mist inlet pipeline 4 in the culture cavity 11 is located at 1 / 3 of the height of the culture cavity 11, which are distributed in the middle of the upper and lower parts.
[0040] Component layout: the humidification pipeline components (including the ultrasonic atomizer 21) are small in size and are placed at the bottom of the box body 1 without occupying space, and a large-capacity water storage tank 29 is arranged beside the humidification pipeline components. The mist outlet pipeline 3 and the mist inlet pipeline 4 are embedded in the foamed heat preservation layer of the box body 1, which has the functions of beauty, heat preservation and protection.
[0041] Material and sealing: the bottom 22 and the upper cover 23 of the humidifier 2 are made of 304 stainless steel, the inner and outer surfaces are electrolytically polished, and the inner surface has a flash silver anti-rust coating. The bottom 22, the ultrasonic atomizer 21 and the float ball valve 24 are respectively sealed by sealing pads and sealing ring lock nuts. The internal components of the humidifier 2 pipeline components are sealed by sealing pads to keep the humidification cycle sealed.
[0042] Water level control: the float ball valve 24 controls the water level in the bottom 22 of the humidifier 2. When the water level is low, a water replenishment signal is sent, the control system starts the water valve 7 and the water pump 8 to pump water from the water storage tank 29, and when the water replenishment is completed, the float ball of the float ball valve 24 floats up to cut off the circuit. The baffle of the float ball valve 24 is installed on the upper cover 23 and covers the float ball valve 24, which reduces the influence of water level fluctuation on the float ball and avoids frequent operation of the water valve 7 and the water pump 8.
[0043] Interface setting: the water inlet hole CPC quick interface 26 is connected with the external water storage tank 29, the water valve 7 and the water pump 8 are used to pump water to the humidification bottom 22; the overflow hole CPC quick interface 27 is connected with the water collecting groove 221 drain pipe to collect and discharge the condensed water droplets on the outer surface of the humidification bottom 22 due to temperature difference; the drain hole CPC quick interface 28 is connected with the drain pipe of the humidification bottom 22 to facilitate the cleaning of impurities in the bottom 22.
[0044] Insulation design: the humidifier 2 pipeline components and the bottom of the box body 1 are isolated by insulation pads 9 and insulation plates 10 to prevent interference with the atomization of the atomizer.
[0045] The parts of the present application not described in detail are prior art, and therefore the present application does not describe them in detail.
[0046] It can be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of one element can be one, and in another embodiment, the number of the element can be multiple, and the term "one" cannot be understood as a limitation on the number.
[0047] Although the terms such as box 1, humidifier 2, misting pipeline 3, misting pipeline 4, return air fan 5, return air flow guide cover 6, water valve 7, water pump 8, insulation pad 9, insulation plate 10, culture cavity 11, ultrasonic atomizer 21, base 22, upper cover 23, float ball valve 24, upper cover sealing pad 25, water inlet hole CPC quick connector 26, overflow hole CPC quick connector 27, drain hole CPC quick connector 28, water storage tank 29, water receiving groove 221, inclined pipe opening 31 are used more in this paper, the possibility of using other terms is not excluded. The use of these terms is only to facilitate the description and explanation of the essence of the application; any additional limitation is contrary to the spirit of the application.
[0048] The present application is not limited to the above best mode, and anyone can derive other various forms of products under the inspiration of the present application, but regardless of any changes in shape or structure, any technical solution with the same or similar to the present application falls within the scope of the present application.
