[0028] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0029] An incubator is a commonly used in vitro cell culture device, allowing for precise control of temperature, carbon dioxide concentration, and humidity as needed. Meanwhile, given the known antioxidant properties of hydrogen, including its ability to promote cell proliferation, maintain cell quality, preserve differentiation, inhibit apoptosis, optimize the culture environment, and regulate immunity, the delivery of hydrogen to incubators has become a trend. Existing incubators also incorporate PTC humidification systems to humidify the culture chamber. However, current PTC humidification systems introduce high-temperature, near-saturated water vapor into the culture chamber, with a dew point temperature much higher than the chamber temperature. This vapor easily condenses inside the pipes, and without proper treatment of the humidification inlet, water can be sprayed into the culture chamber.

[0030] like Figures 1 to 6 As shown, this disclosure provides a humidification system and an incubator for use in an incubator, which can deliver steam into the incubation chamber 11 through a humidifier 20 and a humidification pipe 30, and can prevent condensate in the humidification pipe 30 from being blown into the incubation chamber 11.

[0031] like Figures 1 to 6As shown, the present disclosure provides a humidification system for an incubator. The incubator comprises a cabinet 10 provided with an incubation chamber 11. The humidification system comprises a humidifier 20 and a humidification tube 30. The humidifier 20 comprises a housing 21 provided with a water storage cavity, and a first heating device 22 arranged in the water storage cavity. The humidification tube 30 is connected to the water storage cavity, and at least partially located in the incubation chamber 11. The part of the humidification tube 30 located in the incubation chamber 11 is provided with upward steam holes. The humidifier 20 inputs steam into the incubation chamber 11 through the humidification tube 30.

[0032] Specifically, the incubator comprises a cabinet 10 provided with an incubation chamber 11. The housing 21 of the humidifier 20 is mounted on the cabinet 10, and the housing 21 is located outside the incubation chamber 11. The housing 21 is provided with a hollow water storage cavity, and the first heating device 22 is arranged in the water storage cavity. The first heating device 22 is used to heat the moisture in the water storage cavity to generate steam. The first end of the humidification tube 30 is connected to the water storage cavity through an air inlet, and the air inlet is connected to the upper half of the water storage cavity. The second end of the humidification tube 30 extends into the incubation chamber 11, and the part of the humidification tube 30 located in the incubation chamber 11 is provided with steam holes. In this way, when it is necessary to humidify the incubation chamber 11, the first heating device 22 can be controlled to operate to heat the moisture in the water storage cavity and generate steam. The steam flows upward to the air inlet of the humidification tube 30 and flows into the humidification tube 30. The steam in the humidification tube 30 flows into the incubation chamber 11 through the steam holes to humidify the incubation chamber 11. Since the temperature of the steam is higher than the temperature of the wall of the humidification tube 30, the steam will condense into condensed water when flowing in the humidification tube 30. Therefore, by opening the steam holes upward, the condensed water can be prevented from flowing into the incubation chamber 11 from the steam holes. In this way, the humidifier 20 and the humidification tube 30 can be used to deliver steam into the incubation chamber 11, and the condensed water in the humidification tube 30 can be prevented from being blown into the incubation chamber 11.

[0033] As shown, the second end of the humidification tube 30 is higher than the first end of the humidification tube 30, i.e. the humidification tube 30 extends upward. In this way, the condensed water can be prevented from accumulating at the second end of the humidification tube 30, and the condensed water can be further prevented from overflowing from the steam holes into the incubation chamber 11. Figures 1 to 6

[0034] Optionally, the first end of the humidification tube 30 is connected to the water storage cavity, and the second end of the humidification tube 30 extends upward into the incubation chamber 11. The part of the humidification tube 30 located in the incubation chamber 11 extends horizontally first, and then bends upward, and the steam holes are arranged at the end of the second end of the humidification tube 30. In this way, the condensed water can accumulate in the horizontally extending part of the humidification tube 30, so as to further prevent the condensed water from flowing into the incubation chamber 11 from the steam holes.

[0035] ​Optionally, if the portion of the humidifying pipe 30 located within the culture chamber 11 extends horizontally and then bends upwards, the humidifying pipe 30 is provided with multiple steam holes located on the upward-bending portion, with one steam hole located at the second end of the humidifying pipe 30. This configuration improves the humidification efficiency of the humidification system for the culture chamber 11.

[0036] Optionally, the first end of the humidifying pipe 30 is connected to the water storage chamber, and the second end of the humidifying pipe 30 extends upward into the culture chamber 11. The portion of the humidifying pipe 30 extending into the culture chamber 11 is horizontally positioned, and the steam vent is located on the upper half of the pipe wall. This configuration simplifies the structure of the humidifying pipe 30.

[0037] Optionally, when the humidifying pipe 30 extends horizontally into the culture chamber 11, the humidifying pipe 30 is provided with multiple steam holes, which are evenly spaced along the length of the humidifying pipe 30 on the pipe wall. This arrangement can improve the humidification efficiency of the humidification system for the culture chamber 11.

[0038] Optionally, the humidifier 20 is positioned in the housing 10 corresponding to the incubation chamber 11 to shorten the length of the humidification tube 30, thereby reducing the amount of condensate in the humidification tube 30.

[0039] like Figures 2 to 6 As shown, in some embodiments, the humidifying pipe 30 includes a connecting pipe section 31, a steam pipe section 32, and a condenser pipe section 33. The connecting pipe section 31 includes a first end connected to the water storage chamber and a second end extending to the incubation chamber 11; the steam pipe section 32 is connected to the second end of the connecting pipe section 31 and extends upward, and a steam hole is provided at the upper end of the steam pipe section 32; the condenser pipe section 33 is connected to the connecting pipe section 31 and the steam pipe section 32, and the condenser pipe section 33 extends horizontally or downward.

[0040] Specifically, the first end of the connecting pipe section 31 is connected to the water storage chamber, and the second end of the connecting pipe section 31 extends into and connects to the culture chamber 11. The first end of the steam pipe section 32 is connected to the second end of the connecting pipe section 31, and the second end of the steam pipe section 32 is bent upwards, with a steam hole located at the second end of the steam pipe section 32. The first end of the condenser pipe section 33 is connected to the second end of the connecting pipe section 31 and the first end of the steam pipe section 32, and the condenser pipe section 33 extends horizontally or bends downwards. In this way, the steam in the water storage chamber flows through the connecting pipe section 31 to the steam pipe section 32 and flows into the culture chamber 11 through the steam hole. The condensate at the steam pipe section 32 can flow downwards along the pipe wall to the condenser pipe section 33. With this arrangement, steam can be delivered to the culture chamber 11 through the steam pipe section 32, and the condensate in the humidifying pipe 30 can be collected through the condenser pipe section 33 to prevent condensate from flowing into the chamber.

[0041] Optionally, the length of the steam pipe section 32 is greater than or equal to a preset length, and the distance between the steam hole and the condensation pipe section 33 is greater than or equal to a preset distance. The distance between the steam hole and the condensation pipe section 33 is greater than or equal to 1 cm, for example, the distance between the steam hole and the condensation pipe section 33 can be 1 cm, 2 cm, 3 cm, 4 cm or 5 cm. In this way, the condensed water can be further prevented from flowing into the culture chamber 11 through the steam hole.

[0042] Optionally, the connecting pipe section 31, the steam pipe section 32 and the condensation pipe section 33 can be integrally formed to avoid gaps at the connection, or can be fixedly connected by fasteners and provided with sealing members at the connection to facilitate the processing and transportation of the humidification pipe 30.

[0043] As shown in Figures 1 to 6 In some embodiments, the humidification system further comprises a water storage tank 41 and a water pump 42. The water pump 42 comprises a pump inlet connected to the water storage tank 41 and a pump outlet connected to the water storage cavity. Specifically, the water storage tank 41 is arranged in the tank body 10, and the size of the water storage tank 41 is greater than that of the water storage cavity. The pump inlet of the water pump 42 is communicated with the water storage tank 41 through the water supply pipe 44, and the pump outlet of the water pump 42 is communicated with the water storage cavity to transport the water in the water storage tank 41 into the water storage cavity. It can be understood that in order to shorten the length of the humidification pipe 30, the humidifier 20 is generally arranged on the side wall of the tank body 10, and therefore the weight of the humidifier 20 needs to be less than or equal to a preset weight in order to avoid the humidifier 20 from falling off. Therefore, by providing the water storage tank 41 and the water pump 42 for supplying water to the humidifier 20, the weight of the humidifier 20 itself can be reduced while ensuring the humidification effect and endurance of the humidifier 20.

[0044] Optionally, the water pump 42 is a peristaltic pump.

[0045] As shown in Figures 1 to 6 In some embodiments, the humidification system further comprises a water collecting pipe 43. The water collecting pipe 43 is used to communicate the condensation pipe section 33 with the water storage tank 41 to introduce the condensed water in the condensation pipe section 33 into the water storage tank 41, or the water collecting pipe 43 is used to communicate the condensation pipe section 33 with the water storage cavity to introduce the condensed water in the condensation pipe section 33 into the water storage cavity.

[0046] Specifically, the first end of the condensation pipe section 33 is communicated with the connecting pipe section 31 and the steam pipe section 32, and the second end of the condensation pipe section 33 is arranged to extend in the horizontal direction or to extend downwardly and bent. The first end of the water collecting pipe 43 is communicated with the second end of the condensation pipe section 33, and the second end of the water collecting pipe 43 is communicated with the water storage tank 41 or the water storage cavity. In this way, the condensed water in the humidification pipe 30 can be transported into the water storage tank 41 or the water storage cavity through the water collecting pipe 43 to realize the recycling of the condensed water and be more environmentally friendly.

[0047] Optionally, in the case that the water collecting pipe 43 is connected to the condensing pipe section 33 and the water storage tank 41, the water storage tank 41 is located below the condensing pipe section 33, i.e. the second end of the water collecting pipe 43 is arranged to extend downwardly, so that the condensed water can flow into the water storage tank 41 under the action of gravity. In the case that the water collecting pipe 43 is connected to the condensing pipe section 33 and the water storage cavity, the humidifier 20 is located below the condensing pipe section 33, so that the condensed water can flow into the water storage cavity under the action of gravity.

[0048] In some embodiments, the first heating device 22 is a PTC heating element.

[0049] Specifically, the humidifier 20 or the incubator further comprises a power supply, which is electrically connected to the first heating device 22 to supply power to the first heating device 22, so that the first heating device 22 heats the moisture in the water storage cavity. It can be understood that, compared with other heating devices, the PTC heating element has the advantages of automatic constant temperature anti-overheating, high efficiency, energy saving, long service life, compact structure, etc., and therefore the use of the PTC heating element as the first heating device 22 has significant advantages in safety and stability.

[0050] As shown in FIG. 1, the incubator according to the present disclosure further comprises a humidification system for the incubator. The humidification system comprises a humidifier 20 and a humidification pipe 30. The humidifier 20 is arranged outside the incubation chamber 11 of the incubator 10, and the humidification pipe 30 is connected to the humidifier 20 and the incubation chamber 11. The humidifier 20 can supply steam to the incubation chamber 11 through the humidification pipe 30. Figures 1 to 6 Specifically, the incubator comprises an incubator body 10, which is provided with an incubation chamber 11. The humidifier 20 of the humidification system is arranged outside the incubation chamber 11 of the incubator body 10, and the humidification pipe 30 of the humidification system is connected to the humidifier 20 and the incubation chamber 11. The humidifier 20 can supply steam to the incubation chamber 11 through the humidification pipe 30. The use of the humidification system according to the present disclosure in the incubator can supply steam to the incubation chamber 11 through the humidifier 20 and the humidification pipe 30, and can avoid the condensed water in the humidification pipe 30 from being blown into the incubation chamber 11.

[0051] Specifically, the incubator comprises an incubator body 10, which is provided with an incubation chamber 11. The humidifier 20 of the humidification system is arranged outside the incubation chamber 11 of the incubator body 10, and the humidification pipe 30 of the humidification system is connected to the humidifier 20 and the incubation chamber 11. The humidifier 20 can supply steam to the incubation chamber 11 through the humidification pipe 30. The use of the humidification system according to the present disclosure in the incubator can supply steam to the incubation chamber 11 through the humidifier 20 and the humidification pipe 30, and can avoid the condensed water in the humidification pipe 30 from being blown into the incubation chamber 11.

[0052] Figure 3 As shown in FIG. 1, in some embodiments, the incubator further comprises a plurality of second heating devices 12. The plurality of side walls and the upper end face of the incubation chamber 11 are respectively provided with at least one second heating device 12.

[0053] Specifically, the second heating device 12 is arranged on the side wall and the upper end face of the incubation chamber 11, and the second heating device 12 is used to heat the corresponding side wall or upper end face.

[0054] ​It can be understood that the steam delivered by the humidification system to the culture chamber 11 is generally high in temperature, and therefore if the steam directly contacts the side wall surface or the upper end surface of the culture chamber 11, the steam can condense into condensed water on the side wall surface or the upper end surface of the culture chamber 11. Therefore, when the culture chamber 11 is humidified by the humidification system, the side wall surface and the upper end surface of the culture chamber 11 can be heated by the plurality of second heating devices 12 first to increase the temperature of the side wall surface and the upper end surface of the culture chamber 11, thereby avoiding the condensation of the steam into condensed water in the culture chamber 11.

[0055] In the above embodiment, the side wall surface of the culture chamber 11 includes the left side wall, the right side wall, and the back wall, i.e., the left side wall, the right side wall, the back wall, and the upper end surface of the culture chamber 11 are respectively provided with at least one second heating device 12.

[0056] Alternatively, the second heating device 12 can be a PTC heating element or an electric heating wire, as long as it can achieve rapid heating of the side wall surface and the upper end surface of the culture chamber 11.

[0057] In some embodiments, the culture chamber 11 further comprises a temperature sensor 51 and a control device. The temperature sensor 51 is configured to obtain an indoor temperature of the culture chamber 11; the control device is electrically connected to the temperature sensor 51 and the second heating device 12, respectively; in a case where the indoor temperature is less than or equal to a preset temperature, the control device controls the second heating device 12 to operate to heat the culture chamber 11 to a target temperature; wherein the difference between the preset temperature and the target temperature is greater than 0°C and less than or equal to 5°C.

[0058] Specifically, the temperature sensor 51 comprises a first detection probe and a plurality of second detection probes, the first detection probe is configured to obtain an indoor temperature in the culture chamber 11, and the plurality of second detection probes are respectively arranged on the side wall surface and the upper end surface of the culture chamber 11 to obtain the temperatures of the corresponding side wall surface and upper end surface. In a case where the indoor temperature is less than or equal to a preset temperature, the control device controls the second heating device 12 to operate to heat the culture chamber 11 to a target temperature to avoid condensation of steam in the culture chamber 11. Wherein the target temperature is less than the preset temperature, the difference between the preset temperature and the target temperature is greater than 0°C and less than or equal to 5°C, and in particular the difference between the preset temperature and the target temperature can be 1°C, 2°C, 3°C, 4°C or 5°C.

[0059] As shown in FIG. 1, Figure 3 In some embodiments, the incubator further comprises a third heating device 13. The third heating device 13 is arranged on the lower end surface of the culture chamber 11, and the control device is further electrically connected to the third heating device 13; in a case where the indoor temperature is greater than or equal to the target temperature, the control device controls the second heating device 12 to stop and controls the third heating device 13 to operate to heat the culture chamber 11 to the preset temperature.

[0060] Specifically, the third heating device 13 is arranged at the lower end surface of the incubation chamber 11, and is configured to heat the lower end surface of the incubation chamber 11. After the second heating device 12 heats the indoor temperature of the incubation chamber 11 to the target temperature, the control device controls the second heating device 12 to stop heating, and controls the third heating device 13 to operate, so as to continue heating the incubation chamber 11 to the preset temperature by the third heating device 13.

[0061] Optionally, the third heating device 13 can be a PTC heating element or an electric heating wire, as long as it can realize rapid heating of the lower end surface of the incubation chamber 11.

[0062] Optionally, the power box 10 of the plurality of second heating devices 12, and the power of the third heating device 13 is greater than that of the second heating device 12.

[0063] Optionally, after the temperature in the incubation chamber 11 is heated to the preset temperature, the control device can further control the plurality of second heating devices 12 to operate, so as to maintain the temperature in the incubation chamber 11 by the second heating device 12 and the third heating device 13 at the same time.

[0064] In some embodiments, the control device is further electrically connected with a humidification system; in the case that the indoor temperature is greater than or equal to the target temperature, the humidification system is controlled to deliver steam to the incubation chamber 11.

[0065] Specifically, after the indoor temperature of the incubation chamber 11 reaches the target temperature, the humidification system is controlled to humidify the incubation chamber 11, and since the humidification system delivers high-temperature steam to the incubation chamber 11, the temperature of the incubation chamber 11 can be further heated to the preset temperature by the high-temperature steam. In this way, the energy-saving effect can be achieved.

[0066] In the above disclosed embodiments, the working process of the incubator is as follows: the temperature sensor 51 acquires the indoor temperature of the incubation chamber 11, and in the case that the indoor temperature of the incubation chamber 11 is lower than the preset temperature, the control device controls the second heating device 12 to operate, so as to heat the side wall surface and the upper end surface of the incubation chamber 11 by the second heating device 12, and further heat the indoor temperature of the incubation chamber 11 to the target temperature. After the indoor temperature of the incubation chamber 11 is greater than or equal to the target temperature, the control device controls the second heating device 12 to stop, and controls the third heating device 13 and the humidification system to operate, so as to continue heating the incubation chamber 11 by the third heating device 13, and to humidify the incubation chamber 11 by the humidification system, at this time, the third heating device 13 and the humidification system can jointly heat the indoor temperature of the incubation chamber 11 to the preset temperature. After the indoor temperature of the incubation chamber 11 reaches the preset temperature, the control device can control the second heating device 12 to operate, so as to uniformly heat the incubation chamber 11 together with the third heating device 13 and the humidification system, so as to maintain the indoor temperature of the incubation chamber 11.
