It should be noted that, without conflict, the embodiments of the present disclosure and features of the embodiments may be combined with each other.

Typically, the pH of the cell culture broth is between 7.0 and 7.4, and the carbon dioxide incubator creates an environment that allows for better growth of cells or tissues by controlling the ambient conditions. For example, a carbon dioxide incubator can provide constant ph, stable temperature, higher relative humidity, and stable carbon dioxide concentration. Accordingly, the carbon dioxide incubator has become one of the conventional instruments commonly used in laboratories, and is widely used for research and production in medicine, immunology, genetics, microorganisms, agricultural science, and pharmacology.

The air duct plate in the carbon dioxide incubator is generally rectangular, and a rectangular air duct is directly defined by the side panels of the air duct plate. After the fan sucks air into the air duct, the fan blades of the fan can throw the air out to the periphery. Part of the air is blown directly to the side panels of the duct board by the blower and then bounces back to the other direction by the side panels of the duct board. The air flow can not normally participate in the air circulation in the incubator, but also can influence the air flow which normally participates in the air circulation. This increases the turbulence of the air flow in the incubator, thereby reducing the effect of air circulation in the incubator.

At present, under the condition that the air flow in the incubator is relatively disordered, the effect of air circulation required by experiments is generally ensured by increasing the rotating speed of the fan. However, increasing the rotation speed of the fan also causes problems such as noise and vibration, which may affect the final result of the experiment.

As shown in fig. 1 to 6, the embodiment of the present disclosure provides an incubator including a cabinet 10, an air duct plate 20, a scroll casing 30, and a blower 40. The case 10 includes a receiving chamber provided with an opening. The air duct plate 20 is installed in the accommodating cavity, and is provided with an air inlet 21 and an air outlet 22 communicated with the accommodating cavity. The volute 30 is disposed on a side of the air duct plate 20 facing the inner wall surface of the accommodating chamber, and is used for defining an air duct communicating the air inlet 21 and the air outlet 22. The fan 40 is disposed at a position corresponding to the air inlet 21 in the air duct, and can suck air flow through the air inlet 21. The volute 30 has an arc structure adapted to the fan 40.

Specifically, the accommodating chamber is provided with an opening and a first inner wall surface 11 opposite to the opening, and the duct plate 20 is fixedly mounted to the first inner wall surface 11 of the accommodating chamber. The scroll case 30 is disposed between the air duct plate 20 and the first inner wall surface 11 of the receiving chamber to define an air duct between the air duct plate 20 and the first inner wall surface 11. The spiral case 30 has an arc-shaped structure corresponding to the fan 40, and an arc-shaped air channel is defined by the inner wall surface of the spiral case 30. The fan 40 is disposed in the middle of the air duct, and can blow the air in the accommodating cavity into the air duct through the air inlet 21. Wherein, setting the spiral case 30 as arc structure in order to inject arc wind channel can improve the order of air current in the wind channel, and then improves the effect of air current circulation in the incubator.

As shown in fig. 4 to 6, when the blower 40 is turned on, the blower 40 may suck the air in the accommodating chamber into the air duct through the air inlet 21, and the air flow in the air duct contacts the inner wall surface of the volute 30, is guided to the air outlet 22 by the inner wall surface of the volute 30, and is blown into the accommodating chamber to complete the air circulation of the incubator.

Compared with the existing incubator, the incubator provided by the application can enhance the effect of air flow circulation in the incubator when the rotating speed of the fan 40 is not increased, and further avoid the influence of noise and vibration generated by the fan 40 on experimental results.

Alternatively, the width of the scroll case 30 is the same as the distance between the air duct plate 20 and the first inner wall surface 11, i.e., the scroll case 30 extends from the air duct plate 20 toward the first inner wall surface 11 of the accommodating chamber and is connected to the first inner wall surface 11. By the arrangement, gaps are avoided between the volute 30 and the air duct plate 20 and between the volute and the first inner wall surface 11, and further airflow turbulence caused by airflow leakage in the air duct is avoided.

Optionally, a sealing structure is provided between the volute 30 and the first inner wall surface 11, which may further reduce the risk of air leakage.

Alternatively, the duct plate 20 may be fixedly mounted to the first inner wall surface 11 of the accommodating chamber by a fastener such as a bolt.

Optionally, the fan 40 is a centrifugal fan 40, including an air intake for air suction. The air intake of the blower 40 is coaxially disposed with the air inlet 21, so as to improve the air suction efficiency of the blower 40 through the air inlet 21.

It will be appreciated that in the case of rotation of the blades of the centrifugal fan 40, the centrifugal fan 40 may draw air in through the intake and throw the air out around through the gaps between the blades. Therefore, the arc-shaped structure matched with the fan 40 is arranged on the volute 30 to guide the airflow thrown out by the fan 40 to the periphery, so that the order of the airflow in the air duct is improved.

As shown in fig. 2-4, in some embodiments, the duct board 20 includes a main panel 201 provided with an air intake 21 and a side panel 202 provided with an air outlet 22. Wherein the side panels 202 extend from the main panel 201 to the inner wall surfaces of the accommodation cavities corresponding to the main panel 201.

Specifically, the scroll casing 30 is disposed between the main panel 201 of the air duct board 20 and the first inner wall surface 11 of the accommodating chamber to define an air duct between the main panel 201 and the first inner wall surface 11. The main panel 201 is provided with a first opening to form the air inlet 21, and the fan 40 is disposed at a position of the air duct corresponding to the air inlet 21. The side panel 202 is provided along the edge of the main panel 201, and extends to the first inner wall surface 11 of the accommodating chamber and is connected to the first inner wall surface 11. The side panel 202 of the volute 30 is provided with a second opening to constitute the air outlet 22.

It will be appreciated that, since the centrifugal fan 40 will throw the air flow around, the side panel 202 of the volute 30 with the air outlet 22 can make the centrifugal fan 40 directly blow the air flow from the air outlet 22 into the accommodating cavity, so as to improve the air flow effect of the incubator.

As shown in fig. 2, alternatively, in the case where the side panel 202 is provided with the second opening to form the air outlet 22, the size of the second opening may be the same as the size of its corresponding side panel 202, that is, the side panel 202 may be completely provided with the second opening to form the air outlet 22.

Optionally, a sealing structure is provided between the side panel 202 and the first inner wall surface 11.

In some practical applications, the air inlet 21 is disposed in the middle of the main panel 201, and the air outlet 22 is disposed in the side panel 202. The air duct is used for communicating the air inlet 21 and the air outlet 22, and the fan 40 is arranged at a position corresponding to the air inlet 21 in the air duct. Thus, the blower 40 may form a circulation air path in the incubator, which draws air from the middle of the duct board 20 and discharges air from the edges.

In other implementations, the side panels 202 include upper and lower side panels 202, 202 disposed opposite the upper and lower sides of the main panel 201. The air inlet 21 is disposed on the half of the main panel 201 near the upper panel 202, and the air outlet 22 is disposed on the lower panel 202. The air duct is used for communicating the air inlet 21 and the air outlet 22, and the fan 40 is arranged at a position corresponding to the air inlet 21 in the air duct. Thus, the blower 40 may form a circulation air path in the incubator that draws air from the upper half of the duct plate 20 and discharges the air from the lower edge.

As shown in fig. 3 and 4, in some embodiments, the duct board 20 is provided with a plurality of air outlets 22, and the duct may respectively communicate the air inlets 21 with the plurality of air outlets 22.

Specifically, a plurality of air outlets 22 are provided on the side panel 202 of the air duct board 20, and the fan 40 can blow air to the plurality of air outlets 22 through the air duct and into the accommodating cavity through the plurality of air outlets 22. So set up, can improve incubator internal air circulation's effect.

As shown in fig. 3 to 6, in some practical applications, the duct board 20 includes a main panel 201 and a side panel 202, and the side panel 202 includes an upper side panel 202 and a lower side panel 202 disposed opposite to the upper and lower sides of the main panel 201. The middle part of the main panel 201 is provided with a first opening to constitute the air inlet 21, the upper side panel 202 is provided with a second opening to constitute the first air outlet 22, and the lower side panel 202 is provided with a second opening to constitute the second air outlet 22. The air duct comprises an upper air duct used for communicating the air inlet 21 with the first air outlet 22 and a lower air duct used for communicating the air inlet 21 with the second air outlet 22. The fan 40 is disposed in the air duct at a position corresponding to the air inlet 21. The blower 40 may suck air through the air inlet 21 and blow air flow to the first air outlet 22 and the second air outlet 22 through the upper duct and the lower duct, respectively. The first air outlet 22 and the second air outlet 22 have the same size. Thus, a circulation air path for sucking air from the middle portion of the air duct board 20 and discharging air from the upper and lower edges can be formed. By the arrangement, the uniformity of air flow circulation in the incubator can be further ensured.

As shown in fig. 1 and 5, in some embodiments, the incubator further comprises a water tank 70. The water tank 70 is disposed in the receiving chamber for storing water. The air duct board 20 includes at least one air outlet 22 corresponding to the water tank 70, so that the air flow blown into the accommodating chamber can flow through the water tank 70.

Specifically, the water tank 70 is disposed at the bottom end surface of the accommodating cavity, and the side panel 202 of the air duct board 20 near one side of the water tank 70 is provided with at least one air outlet 22, and the air outlet 22 is located above the water tank 70. Thus, when the fan 40 circulates air in the incubator, a portion of the circulating air flow may be caused to flow through the water tank 70. So configured, moisture may be carried to other locations of the incubator by the circulating air flow through the water trough 70, thereby increasing the humidity within the incubator.

Optionally, the air outlet 22 of the air duct board 20 corresponding to the water tank 70 is further provided with an air door. The incubator further comprises a humidity sensor electrically connected with the air door for detecting humidity in the incubator. In the case that the air duct board 20 is provided with a plurality of air outlets 22 and the humidity in the incubator is greater than or equal to the preset humidity, the humidity sensor can transmit a high humidity detection signal to the damper, and the damper closes the air outlets 22 corresponding to the water tank 70 after receiving the high humidity detection signal. Under the condition that the humidity in the incubator is less than the preset humidity, the humidity sensor can transmit a low humidity detection signal to the air door, and the air door opens the air outlet 22 corresponding to the water tank 70 after receiving the low humidity detection signal.

As shown in fig. 1 and 5, in some embodiments, the incubator further comprises a detection assembly 50. The detecting assembly 50 is disposed in the accommodating cavity at a position corresponding to the air outlet 22, and is used for detecting the carbon dioxide concentration of the air flow.

Specifically, the detecting assembly 50 includes a detecting probe fixedly disposed in the accommodating cavity of the box 10, and the detecting probe is disposed corresponding to the air outlet 22. The detection probe is arranged at the position corresponding to the air outlet 22, so that the detection probe can timely detect the carbon dioxide change condition in the circulating air flow, and further the carbon dioxide level in the incubator is ensured.

In practical application, if the air duct board 20 is provided with a plurality of air outlets 22, the detection assembly 50 may be provided with detection probes at positions corresponding to one of the air outlets 22, or may be provided with a plurality of detection probes at positions corresponding to the air outlets 22, where the number and positions of the detection probes may be set according to practical requirements.

Optionally, the incubator further comprises a display assembly. The display assembly is disposed outside the case 10 and electrically connected to the detection assembly 50, for displaying the carbon dioxide information detected by the detection assembly 50.

As shown in fig. 2-6, in some embodiments, the air outlets 22 include a primary air outlet 221 and a secondary air outlet 222. The incubator further comprises an air deflector 23. The air deflector 23 is disposed in the air duct at a position corresponding to the air outlet 22, and is used for dividing the air duct into a first air duct 31 communicated with the main air outlet 221 and a second air duct 32 communicated with the secondary air outlet 222. The detecting assembly 50 is disposed in the accommodating cavity at a position corresponding to the secondary air outlet 222.

Specifically, the blower 40 may blow a part of the air flow into the accommodating chamber through the first air duct 31 and the main air outlet 221 to complete the air flow circulation; another part of the air flow is blown to the detecting assembly 50 through the second air duct 32 and the secondary air outlet 222, so that the detecting assembly 50 can timely detect the carbon dioxide change in the air flow. By the arrangement, the detection assembly 50 can be arranged at other positions under the condition that the track of the circulating air flow is not changed so as to meet the detection requirement, and meanwhile, the interference of the detection assembly 50 on the circulating air flow can be avoided.

Alternatively, one end of the air deflector 23 may be fixedly mounted to the side panel 202 by a fastener, and the air deflector 23 is disposed between the primary air outlet 221 and the secondary air outlet 222. Wherein the air deflector 23 is disposed near the secondary air outlet 222, and the air deflector 23 extends into the air duct to divide the air duct into a first air duct 31 and a second air duct 32.

In some embodiments, the width of the second air channel 32 is less than the width of the first air channel 31.

Specifically, the width of the second air duct 32 is smaller than that of the first air duct 31, so that the airflow blown to the first air duct 31 by the fan 40 is ensured to be larger than that of the second air duct 32, and the airflow in the incubator can be ensured to complete normal airflow circulation.

It will be appreciated that, in the case where the airflow direction blown by the fan 40 is constant, if the width of the second air duct 32 is greater than that of the first air duct 31, most of the airflow in the air duct is split by the second air duct 32, so as to reduce the airflow rate in the first air duct 31.

In some embodiments, the distance of the detection assembly 50 from the blower 40 is less than or equal to a preset distance.

Specifically, the distance between the detecting component 50 and the fan 40 is smaller than or equal to the preset distance, so that the air flow can be blown to the detecting component 50 by the fan 40 in time, so that the detecting component 50 can detect the carbon dioxide level in the circulating air flow in time.

As shown in fig. 2-6, in some implementations, the duct board 20 includes a main panel 201 and side panels 202. The side panels 202 include an upper side panel 202, a lower side panel 202, and a right side panel 202, wherein the upper side panel 202 and the lower side panel 202 are oppositely provided with an upper side and a lower side of the main panel 201, and the right side panel 202 is provided on the right side of the main panel 201. The middle part of the main panel 201 is provided with a first opening to constitute the air inlet 21, the upper side panel 202 is provided with a second opening to constitute the first air outlet 22, the lower side panel 202 is provided with a second opening to constitute the second air outlet 22, and the right side panel 202 is provided with a second opening to constitute the third air outlet 22. The first air outlet 22 is a primary air outlet 221, and the third air outlet 22 is a secondary air outlet 222. The air duct comprises an upper air duct used for communicating the air inlet 21 with the first air outlet 22 and a lower air duct used for communicating the air inlet 21 with the second air outlet 22. An air deflector 23 is arranged in the upper air duct, and the air deflector 23 is obliquely arranged to the right side panel 202 to divide the upper air duct into a first air duct 31 connected with the first air outlet 22 and a second air duct 32 connected with the third air outlet 22. The fan 40 is disposed in the air duct at a position corresponding to the air inlet 21. The detecting assembly 50 is disposed in the accommodating cavity at a position corresponding to the third air outlet 22. The blower 40 may suck air through the air inlet 21 and blow air flow to the first air outlet 22, the second air outlet 22 and the third air outlet 22 through the first air duct 31, the lower air duct and the second air duct 32, respectively. Thus, the air inlet 21, the first air outlet 22 and the second air outlet 22 can form a circulating air path for sucking air at the middle part of the air duct plate 20 and exhausting air at the upper edge and the lower edge; the third air outlet 22 can guide the air flow to the detecting component 50, so that the detecting component 50 can timely detect the carbon dioxide level of the circulating air flow in the incubator.

Optionally, the size of the secondary air outlet 222 is smaller than or equal to the preset size, and the detecting assembly 50 is disposed corresponding to the secondary air outlet 222. Such an arrangement may further avoid the inability of the detection assembly 50 to timely and accurately detect the carbon dioxide level in the airflow blown out of the secondary air outlet 222 due to the oversized secondary air outlet 222.

As shown in FIG. 1, in some embodiments, the incubator further comprises a filter 60. The filter 60 is disposed at a position of the air duct board 20 corresponding to the air inlet 21, and is used for filtering air flowing through the air inlet 21.

Specifically, the filter 60 is a HEPA (High Efficiency Particulate Air Filter) filter 60, also referred to as a high efficiency air filter 60. The high efficiency air filter 60 can collect particle dust of 0.5 μm or more and various suspended matters, so that it is widely used in dust-free clean workshops such as biological medicine, precision instruments, and optical electronics.

The filter 60 is fixedly installed to the duct board 20 in such a manner as to entirely cover the air inlet 21, and the filter 60 is disposed at both sides of the main panel 201 opposite to the blower 40.

In practical applications, the volute 30 has a wind collecting function, so that the problem of increased circulation resistance of air flow in the incubator caused by the filter 60 is solved by adopting the volute 30 to define the air duct.

In some embodiments, the filter 60 is provided with a sealing structure at the junction with the duct plate 20.

Specifically, a sealing structure is disposed at the connection between the filter 60 and the duct board 20 to leak air at the connection therebetween, thereby affecting the filtering effect of the filter 60 on the circulating air flow.
