As shown in fig. 3 to 10, the bottom plate 116 is recessed downward to form a recess, the cover plate 117 is covered on the recess, and the bottom of the cover plate 117 is provided with a partition 119, and the partition 119 is connected to 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 to the cover plate 117, and the lower end of the partition 119 extends to the bottom plate 116, so that the partition 119 divides the recess formed by the bottom plate 116 into a plurality of compartments.
It should be noted that the partition 119 and the bottom plate 116 are preferably sealed by a gasket, sealant, etc., but the partition 119 and the bottom plate 116 may have a smaller gap, which is smaller than the nominal cross-sectional area described later, so as to avoid a large amount of air leakage between the compartments.
Like this, utilize bottom plate 116 of shell structure 110 and the apron 117 that is located bottom plate 116 top to form and separate the chamber, and then utilize to separate the chamber and form air inlet chamber 020, on the one hand can strengthen shell structure 110's bearing capacity, and on the other hand utilizes shell structure 110's bottom to form air inlet chamber 020, and for other positions of shell structure 110, the bottom shape is more regular, the formation of the chamber 020 of being convenient for admit air, its simple structure, the practicality is strong.
As shown in fig. 3 and 6, the bed 120 is disposed on the cover plate 117.
The bed 120 may be integrally or removably attached to the cover 117. As shown in fig. 8 and 9, when the bed is detachably connected, a plurality of baffles for limiting the bed body 120 may be disposed on the cover plate 117, and a plurality of baffles may be disposed around the bed body 120.
Optionally, the total area of the projections of all the cells in the horizontal plane is a first area, the cross-sectional area of the inner contour of the housing structure 110 at the height position 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, the horizontal plane and the cross section are both parallel to the XY plane.
It should be noted that, in the nmr incubator, the humidified gas is generally introduced into the incubator 100 through the air inlet duct structure 000, so as to provide a constant temperature and humidity environment for the infant, but the temperature of the bed body 120 below the infant is not easily guaranteed, and a large temperature difference may exist between the upper side and the lower side of the body of the infant (for example, when the incubator 100 starts to operate or performs a large temperature and humidity adjustment), so as to cause discomfort.
The proportion 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 bed, 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 kept, and the use experience can be improved.
Optionally, the total area of the projections of all the cells on the bed surface of the bed 120 is a third area, the area of 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 0.6-0.8, for example 0.7. Here, the bed surface of the bed 120 may be defined as the bottom surface of the cavity formed by the bed 120 or the upper surface of the mattress 130.
So, can be under the condition that keeps ventilating, realize the effective heat transfer to bed body 120 through apron 117 to promote and use experience.
Further, the third area is 0.6-0.95 times, for example 0.7-0.9 times the first area. That is to say that separate the chamber and concentrate as far as possible and arrange in bed body 120 below, can effectively conduct heat to bed body 120, can also avoid separating the chamber too close to cultivate the edge of storehouse 100, and then can avoid to a certain extent to cultivate the heat loss of storehouse 100 inside too fast, can reduce the energy consumption to a certain extent.
As shown in fig. 3, in an alternative embodiment of the present invention, the air inlet duct structure 000 comprises a main air inlet channel 010 at least partially located outside the culture chamber 100, a first end of each air inlet cavity 020 is communicated with the first end of the main air inlet channel 010, and a second end of the main air inlet channel 010 is communicated with the ventilation driving device 200.
Illustratively, the first end of the air inlet main channel 010 extends to the inside of the culture compartment 100, that is to say the air inlet chamber 020 communicates with the air inlet main channel 010 inside the culture compartment 100.
Illustratively, the first end of the air inlet cavity 020 extends to the outside of the incubation well 100, that is, the air inlet cavity 020 communicates with the air inlet main channel 010 on the outside of the incubation well 100 (the rear side of the rear wall plate 113).
In this way, by providing the main intake passage 010, direct communication of each intake chamber 020 to the ventilation driving device 200 is avoided, material saving and space arrangement convenience can be achieved to some extent, for example, a heater 300, a humidifier 400 and the like described later can be arranged at the main intake passage 010, and the structure arrangement of the heater 300, the humidifier 400 and the like is facilitated.
As shown in fig. 4 to 8, in an alternative embodiment of the present invention, the air intake cavity 020 includes a first air intake cavity 021 and a second air intake cavity 022, an air outlet 030 of the first air intake cavity 021 is correspondingly disposed at one longitudinal end of the bed body 120, and an air outlet 030 of the second air intake cavity 022 is correspondingly disposed at a side of the bed body 120.
As shown in fig. 5, the outlet 030 of the first inlet cavity 021 is a first outlet 031, and the first outlet is located at the front end of the bed 120 and formed at the seam position between the cover plate 117 and the bottom plate 116.
It should be understood that the first air outlet 031 is farthest away from the ventilation driving apparatus 200, and air intake through the first air intake cavity 021 alone is beneficial to ensure that the air volume of the first air outlet 031 is stable.
As shown in fig. 5, further, the number of the second air intake chambers 022 is multiple, wherein the second air intake chambers 022 include third air intake chambers 0221 and fourth air intake chambers 0222 therein, the air outlets 030 of the third air intake chambers 0221 and the fourth air intake chambers 0222 are respectively located at different sides of the bed 120, and the air outlets 030 of the third air intake chambers 0221 and the fourth air intake chambers 0222 are arranged in a staggered manner.
Specifically, the air outlets 030 of the third air inlet cavity 0221 and the fourth air inlet cavity 0222 are respectively the second air outlet 032 and the third air outlet 033, wherein the air outlets 030 are sequentially sequenced according to the distance from the air outlet 030 to the ventilation driving device 200: a first outlet 031, a third outlet 033, and a second outlet 032.
Thus, a plurality of air outlets 030 are formed on the periphery of the bed body 120 in the culture bin 100, and each air outlet 030 is supplied with air through the separate air inlet cavity 020, which is beneficial to rapidly forming a culture environment with uniform temperature and humidity at each position in the culture bin 100, and also avoids a part of the air outlets 030, such as the first air outlet 031, from being windless to some extent due to too far distance from the ventilation driving device 200.
In order to further obtain better ventilation and air-out effects, the nominal cross-sectional area of the air inlet cavity 020 which is farthest in conveying distance is the largest;
the conveying distance is the distance from the first end of the air inlet cavity 020 to the corresponding air outlet 030, and the calibrated cross-sectional area is the minimum value of the cross-sectional area of the air inlet cavity 020.
For convenience of description, the air outlet area of each air outlet 030 is defined to be larger than the calibrated cross-sectional area of the corresponding air inlet cavity 020, and the air outlet areas of the air outlets 030 are substantially the same.
Taking the first air intake cavity 021 as an example, the distance from the first air outlet 031 to the place where the first air intake cavity 021 is communicated with the air intake main channel 010 is the conveying distance of the first air intake cavity 021. At this time, the nominal cross-sectional areas of the other intake chambers 020, such as the third intake chamber 0221 and the fourth intake chamber, may be the same or different.
Therefore, the maximum calibrated cross-sectional area of the air inlet cavity 020 with the farthest conveying distance, such as the first air inlet cavity 021, is beneficial to ensuring the air outlet amount of the air outlet with the farther distance from the ventilation driving device 200, such as the first air outlet, and is also beneficial to returning air through the air return port 140 arranged at the middle upper part and the like of the rear wall plate 113, so that ventilation circulation is formed, and the ventilation condition of the nuclear magnetic culture bin 100 can be improved to a certain extent.
Optionally, the nominal cross-sectional area of the inlet chamber 020 increases the further the transport distance.
That is, each air inlet cavity 020 follows this rule, and illustratively, as shown in fig. 5, the first air inlet cavity 021, the third air inlet cavity 0221 and the fourth air inlet cavity 0222 have the same height in the up-down direction, and the minimum widths of the first air inlet cavity 021, the third air inlet cavity 0221 and the fourth air inlet cavity 0222 are D1, D2 and D2, respectively, where D1 > D3 > D2. E.g., D1= (1.3-2.4) D2, e.g., D1= (1.8-2) D2, which will not be described in detail herein.
As shown in fig. 3, the nmr compatible incubator further comprises a venturi 500; one end of the venturi tube 500 is connected to the air return port 140 of the culture chamber 100, and the other end is connected to the aeration driving means 200, and the negative pressure suction port of the venturi tube 500 is connected to the air through the filter means 510.
Further, as shown in fig. 2 and 3, the nmr compatible incubator further includes an outer cover 600 and a bottom frame 800, the incubation chamber 100 and the outer cover 600 are longitudinally distributed on the bottom frame 800 (i.e. in the direction of the Y axis in the drawing), the outer cover 600 is located at the rear end of the incubation chamber 100 (i.e. at the end where the rear end is located in the opposite direction of the Y axis), the ventilation driving device 200, the electric cabinet, the heater 300, the humidifier 400 and the venturi tube 500 are all located in the outer cover 600, the rear end of the outer cover 600 is provided with a control panel 610, the control panel 610 is used for man-machine interaction of the whole nmr compatible infant incubator, the upper end of the outer cover 600 can be provided as a spliced cover which can move longitudinally, so as to open the internal space of the outer cover 600, which is not used as a limitation.
The outer cover 600 is provided with an air inlet (not shown in the figure), after the outside air is filtered by the filtering device 510 (the filtering layer may be a purifying cloth or filtering fiber), the outside fresh air is sucked by the negative pressure generated by the venturi tube 500, the fresh air and the return air from the return air inlet 140 are introduced into the cultivation cabin 100 through the air inlet duct structure 000 by the ventilation driving device 200 (for example, a motor-driven fan), and the heater 300 and the humidifier 400 can selectively heat and humidify at the air inlet main channel 010, which will not be described herein.
As shown in fig. 6, the bottom chassis 800 may be a frame body formed by welding rectangular tubes, the nuclear magnetic compatibility incubator may further include a sealing plate 118, the sealing plate 118 is connected to the bottom of the bottom chassis 800, and the bottom chassis 800 is prevented from being exposed, for example, the sealing plate 118 and the bottom plate 116 surround to form an accommodating space for accommodating the bottom chassis 800.
In the above embodiment, the cultivation container 100 is preferably made of a non-magnetic material, the electric device is provided with a corresponding shielding structure, such as an electromagnetic shielding structure, a magnetic shielding structure, and the like, for example, the electric cabinet performs an electromagnetic shielding treatment, and the motor of the ventilation driving device 200 performs a magnetic shielding.
In the above embodiment, the nmr compatible incubator further comprises a temperature and humidity detecting device 700, which may be disposed at the air return opening 140, for example, in the venturi tube 500.
The air outlet 030 is correspondingly provided with an air door adjusting mechanism 900, and the area of the air outlet corresponding to the air outlet 030 is adjusted through the air door adjusting mechanism 900, so that the air quantity is adjusted.
As shown in fig. 11, in the above embodiment, the nmr compatible incubator may further include an adjusting mechanism 900, and the adjusting mechanism 900 is configured to adjust the cross-sectional area of at least one air inlet cavity 020, for example, adjust the cross-sectional area of the third air inlet cavity 0221, and when it adjusts the cross-sectional area of the third air inlet cavity 0221 to decrease its nominal cross-sectional area, the ratio between the nominal cross-sectional areas of the air inlet cavities 020 can be changed, so that the air volume of the outlet 030 of the first air inlet cavity 021 can be increased as required.
Illustratively, when the temperature in the culture bin 100 is increased when the baby performs nuclear magnetic detection, the calibrated cross-sectional area of the air inlet cavity 020 corresponding to the air outlet 030 far away from the nuclear magnetic part of the baby is reduced, so that the air volume of the air outlet 030 near the nuclear magnetic part is increased in a short time. In this case, the power of the ventilation driving apparatus 200 may be increased to stop heating of the heater 300, or the heating of the heater 300 may be switched to cooling, or humidification of the humidifier 400 may be suspended.
For example, when the temperature in the incubation chamber 100 is increased during the head nuclear magnetic resonance examination, the body temperature may be changed by the nuclear magnetic resonance examination, and the nominal cross-sectional area of the third air inlet chamber 0221 may be adjusted to be small by the adjusting mechanism 900.
