The air inlet chamber 020 is at least partially located in the culture chamber 100, and the structure of the air inlet chamber 020 is not limited.
In this way, the air inlet duct structure 000 is set to include a plurality of air inlet chambers 020, so that the air outlets 030 corresponding to the air inlet chambers 020 are independently communicated to the ventilation driving device 200, and air can be discharged from each air outlet 030 in the culture bin 100, so that all air outlets 030 at different positions in the longitudinal direction (i.e. in the Y-axis direction in the figure) of the bed body 120 are communicated with the ventilation driving device 200 through integral cavities, so that most of air driven by the ventilation driving device 200 can be prevented from entering the culture bin 100 from the air outlet 030 close to the ventilation driving device 200 to a certain extent, the temperature and humidity non-uniformity possibly formed in the longitudinal direction in the culture bin 100 due to the fact that the air quantity at the air outlet 030 far from the ventilation driving device 200 is small is avoided, the use experience and comfort of critical people such as infants can be ensured to a certain extent, the culture requirement and the nuclear magnetic compatibility requirement can be considered, and the reliability is high.
In an alternative embodiment of the present invention, the housing structure 110 described above is used to form an air intake cavity 020.
That is, the air inlet cavity 020 is formed at least partially inside the housing structure 110, instead of being formed using, for example, a communication pipe.
The specific manner in which this is accomplished is not limiting, as for example, an air inlet cavity 020 is provided at the top, side or bottom of the housing structure 110.
Optionally, the housing structure 110 includes a bottom plate 116 and a cover plate 117 above the bottom plate 116, the cover plate 117 being connected to the bottom plate 116, and a plurality of compartments for forming an air intake chamber 020 being provided between the cover plate 117 and the bottom plate 116.
As shown in fig. 1 to 3, the case structure 110 further includes a case body 111, a front wall plate 112, and a rear wall plate 113, as an example; the case body 111 is connected to and surrounds a cylindrical structure having openings at both ends in the longitudinal direction, and the front wall plate 112 and the rear wall plate 113 are respectively located at the front end and the rear end (the front end is the end in the positive direction of the Y axis, and the rear end is the end in the negative direction of the Y axis) of the cylindrical structure, and the front wall plate 112 and the rear wall plate 113 are respectively connected to the bottom plate 116.
The case body 111 may include a fixed portion connected to the bottom plate 116 and a movable portion rotatable with respect to the fixed portion, the movable portion of which may be kept relatively locked or unlocked by, for example, a limit knob 115 or the like; the case body 111 may be provided with an operation window 114 at a fixed portion, for example, and the operation window 114 may be opened with respect to the case body 111, which may be kept relatively locked or unlocked by a limit knob 115 or the like.
As shown in fig. 3 to 10, illustratively, the bottom plate 116 is downwardly recessed to form a groove, the cover plate 117 is disposed on the groove, the bottom of the cover plate 117 is provided with a partition 119, the partition 119 is connected with at least one of the bottom plate 116 and the cover plate 117, for example, as shown in fig. 6 and 10, the partition 119 is integrally connected to the bottom of the cover plate 117, that is, the upper end of the partition 119 is connected with the cover plate 117, and the lower end of the partition 119 extends to the bottom plate 116, so that the partition 119 partitions the groove formed by the bottom plate 116 into a plurality of compartments.
It should be noted that sealing treatment is preferably performed between the partition 119 and the bottom plate 116 by a gasket, a sealant, or the like, but a small gap may be provided between the partition 119 and the bottom plate 116, which is small relative to a nominal cross-sectional area described later, so that a large amount of blow-by gas between cells is avoided.
In this way, the bottom plate 116 of the shell structure 110 and the cover plate 117 above the bottom plate 116 are utilized to form the separation cavity, and then the separation cavity is utilized to form the air inlet cavity 020, so that on one hand, the bearing capacity of the shell structure 110 can be enhanced, on the other hand, the bottom of the shell structure 110 is utilized to form the air inlet cavity 020, and compared with other positions of the shell structure 110, the bottom shape is more regular, the formation of the air inlet cavity 020 is facilitated, and the structure is simple and the practicability is strong.
As shown in fig. 3 and 6, the bed 120 is disposed on the cover 117.
The bed 120 may be integrally or detachably connected to the cover 117. As shown in fig. 8 and 9, when detachably connected, a plurality of baffles for limiting the bed 120 may be provided on the cover 117, and the baffles may be provided in plurality around the circumference of the bed 120.
Optionally, the total projected area of all cells in the horizontal plane is a first area, the cross-sectional area of the inner contour of the shell structure 110 at the height of the bed 120 is a second area, and the ratio of the first area to the second area is 0.3-0.75. For example 0.45-0.6, for example 0.5.
Specifically, both the horizontal plane and the cross section are parallel to the XY plane.
In the nuclear magnetic resonance compatible incubator, the air inlet duct structure 000 is generally used to supply heated and humidified air into the incubator 100, so as to provide a constant temperature and humidity environment for the infant, but the temperature of the bed 120 below the infant is not easily ensured, and a large temperature difference may occur between the upper and lower sides of the infant's body (for example, when the incubator 100 is just started or temperature and humidity adjustment is performed to a large extent), which may cause discomfort.
The ratio of the first area to the second area is set to be 0.3-0.75, so that on one hand, ventilation can be performed by utilizing the air inlet channel, and on the other hand, the bottom of the culture, particularly the bottom of the bed body 120, can be heated while ventilation is performed, the temperature and humidity consistency of the peripheral side of the bed body 120 can be maintained, and the use experience can be improved.
Optionally, the total projected area of all the compartments on the bed surface of the bed 120 is a third area, the bed surface of the bed 120 is a fourth area, and the ratio of the third area to the fourth area is 0.5-0.1. For example in a ratio of 0.6 to 0.8, for example 0.7. Here, the bed surface of the bed body 120 may be defined as a bottom surface of the cavity formed by the bed body 120 or an upper surface of the mattress 130.
In this way, effective heat transfer to the bed 120 can be achieved through the cover plate 117 while maintaining ventilation, thereby improving the use experience.
Further, the third area is 0.6-0.95 times, e.g., 0.7-0.9 times, the first area. That is, the compartments are arranged under the bed 120 as centrally as possible, so that not only can the bed 120 be effectively heat-transferred, but also the compartments can be prevented from being too close to the edge of the culturing compartment 100, and further the heat loss in the culturing compartment 100 can be prevented from being too fast to a certain extent, and the energy consumption can be reduced to a certain extent.
In an alternative embodiment of the present invention, as shown in FIG. 3, the inlet plenum structure 000 comprises inlet primary channels 010 at least partially located outside the culture compartment 100, a first end of each inlet plenum 020 being in communication with a first end of the inlet primary channels 010, and a second end of the inlet primary channels 010 being in communication with the aeration drive 200.
Illustratively, a first end of inlet primary channel 010 extends into the interior of culture compartment 100, that is, inlet chamber 020 communicates with inlet primary channel 010 within culture compartment 100.
Illustratively, a first end of the air inlet chamber 020 extends to the exterior of the incubator 100, that is, the air inlet chamber 020 communicates with the air inlet main channel 010 at the exterior of the incubator 100 (the rear side of the rear wall plate 113).
Thus, by providing the air intake main passage 010, each air intake chamber 020 is prevented from being directly communicated to the ventilation driving device 200, materials can be saved to a certain extent and space arrangement can be facilitated, for example, a heater 300, a humidifier 400 and the like described later can be arranged at the air intake main passage 010, and structural arrangement of the heater 300, the humidifier 400 and the like can be facilitated.
As shown in fig. 4 to 8, in an alternative embodiment of the present invention, the air inlet chamber 020 includes a first air inlet chamber 021 and a second air inlet chamber 022, the air outlet 030 of the first air inlet chamber 021 is correspondingly disposed at one longitudinal end of the bed body 120, and the air outlet 030 of the second air inlet chamber 022 is correspondingly disposed at a side of the bed body 120.
As shown in fig. 5, the air outlet 030 of the first air inlet cavity 021 is a first air outlet 031, and the first air outlet is located at the front end of the bed 120 and is formed at the seam position of the cover plate 117 and the bottom plate 116.
It should be appreciated that the distance of the first air outlet 031 from the ventilation driving device 200 is farthest, and the air inlet of the first air outlet 031 is beneficial to ensure the stable air quantity of the first air outlet 031 through the separate first air inlet cavity 021.
As shown in fig. 5, further, the number of the second air inlet chambers 022 is plural, wherein the plurality of second air inlet chambers 022 includes a third air inlet chamber 0221 and a fourth air inlet chamber 0222, air outlets 030 of the third air inlet chamber 0221 and the fourth air inlet chamber 0222 are respectively located at different sides of the bed body 120, and the air outlets 030 of the third air inlet chamber 0221 and the fourth air inlet chamber 0222 are arranged in a staggered manner.
Specifically, the air outlets 030 of the third air inlet chamber 0221 and the fourth air inlet chamber 0222 are the second air outlet 032 and the third air outlet 033, respectively, wherein the air outlets 030 are sequentially ordered according to the distance from the air outlet 030 to the ventilation driving device 200: the first outlet 031, the third outlet 033 and the second outlet 032.
In this way, a plurality of air outlets 030 are formed on the peripheral side of the bed body 120 in the culture bin 100, and each air outlet 030 is fed by an independent air inlet cavity 020, which is favorable for quickly forming a culture environment with consistent temperature and humidity at each position in the culture bin 100, and avoiding that part of the air outlets 030, such as the first air outlets 031, are windless due to too far distance from the ventilation driving device 200 to a certain extent.
In order to further obtain better ventilation and air outlet effects, the nominal cross-sectional area of the air inlet cavity 020 with the farthest conveying distance is maximum;
the conveying distance is the distance from the first end of the air inlet cavity 020 to the corresponding air outlet 030, and the nominal cross-sectional area is the minimum value of the cross-sectional area of the air inlet cavity 020.
For convenience of description, it is defined that the air outlet area of each air outlet 030 is larger than the nominal cross-sectional area of the corresponding air inlet cavity 020, and the air outlet areas of the air outlets 030 are substantially identical.
Taking the first air inlet cavity 021 as an example, the distance from the first air outlet 031 to the position where the first air inlet cavity 021 is communicated with the air inlet main channel 010 is the conveying distance of the first air inlet cavity 021. At this time, the nominal cross-sectional areas of the other intake chambers 020, for example, the third intake chamber 0221 and the fourth intake chamber, may be the same or different.
In this way, setting the nominal cross-sectional area of the air intake chamber 020, such as the first air intake chamber 021, which is farthest from the conveyance distance, to be maximum is advantageous in ensuring the air output of the air outlet, such as the first air outlet, which is farther from the ventilation driving device 200, and also in forming ventilation circulation by the return air inlet 140 provided at the middle upper part, etc., of the rear wall plate 113, so that the ventilation condition of the nuclear magnetic resonance incubator 100 can be improved to some extent.
Alternatively, the greater the delivery distance the greater the nominal cross-sectional area of the intake chamber 020.
That is, each air intake chamber 020 follows this rule, and illustratively, as shown in fig. 5, the heights of the first air intake chamber 021, the third air intake chamber 0221, and the fourth air intake chamber 0222 are uniform in the up-down direction, and the minimum widths of the first air intake chamber 021, the third air intake chamber 0221, and the fourth air intake chamber 0222 are D1, D2, respectively, where D1 > D3 > D2. For example d1= (1.3-2.4) D2, for example d1= (1.8-2) D2, which will not be described in detail here.

Illustratively, when the temperature in the incubator 100 increases during the nuclear magnetic detection of the infant, the nominal cross-sectional area of the air inlet chamber 020 corresponding to the air outlet 030 distant from the nuclear magnetic site of the infant is reduced, thereby increasing the air volume near the air outlet 030 at the nuclear magnetic site in a short time. At this time, the power of the ventilation driving device 200 may be increased, and the heating of the heater 300 may be stopped, or even the heating of the heater 300 may be switched to cooling, and the humidification of the humidifier 400 may be suspended.
For example, when the temperature in the incubator room 100 increases during the head nuclear magnetic resonance examination, the temperature change may be caused by the nuclear magnetic resonance examination, and the nominal cross-sectional area of the third inlet chamber 0221 may be reduced by the adjustment mechanism 900.
