Description

TECHNICAL FIELD

[0001] The present application relates to the field of monitoring devices, in particular to an animal monitoring cage. BACKGROUND

[0002] The animal monitoring cage can provide an adaptive environment for animals and is widely used in postoperative recovery, intensive care and other scenarios of animals. The animal monitoring cages in the prior art all have a serious problem of temperature stratification.

[0003] At present, the refrigeration and heating of the animal monitoring cage are usually completed by a separately purchased refrigeration system and a heating system. Such a refrigeration system and a heating system are often difficult to be directly arranged in the same air duct, and therefore a refrigeration air duct for outputting cold air to the accommodation space and a heating air duct for outputting hot air to the accommodation space need to be separately arranged. Then, the temperature control is achieved by adjusting the cold quantity output by the refrigeration air duct and the heat quantity output by the heating air duct. However, since the density of the cold air is greater than that of the hot air, the cold air will deposit at the bottom of the accommodation space after entering the accommodation space, and the hot air will gather at the upper layer of the accommodation space after entering the accommodation space, thereby causing the problem of temperature stratification.

[0004] In addition, in the scheme of using a separate refrigeration air duct and a heating air duct, with the average temperature in the accommodation space as a reference, the temperature of the air flowing back after being cooled in the refrigeration air duct will be lower than the average temperature in the accommodation space. Similarly, the temperature of the air flowing back after being heated in the heating air duct will be higher than the average temperature in the accommodation space. This condition will further increase the temperature fluctuation inside the accommodation space. SUMMARY

[0005] In order to solve the above problems, the present application provides an animal monitoring cage, which comprises an animal accommodation cage, an air duct assembly, a heating assembly, a refrigeration assembly and a circulating fan. The animal accommodation cage has an accommodation space for accommodating animals. The air duct assembly has an air duct in communication with the accommodation space. The refrigeration assembly comprises an evaporator. The evaporator and the heating assembly are arranged in the air duct, so that the air in the accommodation space enters the air duct under the action of the circulating fan, and then circulates to the accommodation space after being adjusted in temperature by the heating assembly and the refrigeration assembly.

[0006] The present application simultaneously arranges the refrigeration assembly and the heating assembly in the same air duct assembly, so that the air can complete the temperature adjustment in the same air duct assembly, and finally the air after temperature adjustment is input into the accommodation space, which greatly improves the problem of serious temperature stratification in the accommodation space.

Of course, some animal monitoring warehouses also increase the oxygen concentration control, carbon dioxide concentration control, infrared physiotherapy, ultraviolet sterilization and other functions.

[0025] The present application sets the refrigeration assembly and the heating assembly in the same air duct assembly, so that the air can complete the temperature adjustment in the air duct instead of the accommodation space.

[0026] Referring to Figure 1The animal monitoring cage 1 comprises an animal accommodating cage 10, an air duct assembly 20, a heating assembly 30, a refrigeration assembly 40 and a circulating fan 50. The animal accommodating cage 10 has an accommodating space 11 for accommodating animals and a cage door (not shown in the figure); the air duct assembly 20 has an air duct 21 communicating with the accommodating space 11; the refrigeration assembly 40 comprises a condenser 41, an evaporator 42 (the evaporator can also be referred to as an evaporating fin or a heat radiating fin), a compressor 43 and a condensing fan 44; the evaporator 42, the heating assembly 30 and the circulating fan 50 are arranged in the air duct 21, so that the air in the accommodating space 11 enters the air duct 21 under the action of the circulating fan 50, and is adjusted in temperature by the heating assembly 30 and the refrigeration assembly 40, and then is circulated to the accommodating space 11.

[0027] In the present application, the refrigeration assembly 40 and the heating assembly 30 are arranged in the same air duct assembly 20 at the same time, so that the air can complete the temperature adjustment in the same air duct assembly 20, and the air adjusted in temperature is finally input into the accommodating space 11, which greatly improves the problem of serious temperature stratification in the animal monitoring cage 1. In the present application, the temperature of the air flowing back through the air duct assembly 20 each time is close to the temperature inside the accommodating space 11, so that the above problem can be improved. The refrigeration assembly 40 comprises the evaporator 42, which can realize humidity control while realizing temperature adjustment in the same air duct assembly 20.

[0028] The animal monitoring cage 1 has a control module 60 coupled to the heating assembly 30, the refrigeration assembly 40 and the circulating fan 50 to control the working states thereof, so as to realize functions such as temperature adjustment and humidity control.

[0029]

Air duct structure

[0030] In some embodiments, the air duct 21 comprises a first section 211, a second section 212 and a third section 213. The third section 213 is connected between the first section 211 and the second section 212; the first section 211 has a first air port 22 communicating with the accommodating space 11; and the second section 212 has a second air port 23 communicating with the accommodating space 11.

[0031] The first air outlet 22 is in communication with the bottom of the accommodation space 11, and the second air outlet 23 is in communication with the top of the accommodation space 11. The density of cold air is greater than that of hot air, and the animal accommodation bin 10 needs to output cold air in most cases. If the second air outlet 23 (air outlet) is below, the cold air tends to accumulate at the bottom rather than spread upwards, which may cause temperature stratification problems. By arranging the second air outlet 23 (air outlet) at the top, the cold air will gradually spread downwards and then diffuse in the entire accommodation space 11, thereby improving the temperature stratification problem. In a direction perpendicular to the flow direction of the gas, the cross-sectional area of the second section 212 is greater than that of the first section 211 and the third section 213. That is, the structure of the first section 211 and the third section 213, and the structure of the second section 212 and the third section 213 can be substantially "T" shaped, or inverted "T" shaped. In this case, due to the larger cross-sectional area, the air speed when the air enters the first air outlet 22 from the accommodation space 11 can be reduced, and the air speed when the air enters the accommodation space 11 from the second air outlet 23 can be reduced, thereby reducing the negative effects of excessive air speed on animals.

[0032] The direction of the first air outlet 22 is different from the extension direction of the third section 213. The direction of the second air outlet 23 can also be different from the extension direction of the third section 213. For example, the direction of the second air outlet 23 can be perpendicular to the extension direction of the third section 213. In this case, the air can be buffered and turned in the second section 212 before entering the accommodation space 11 through the second air outlet 23, avoiding direct blowing on the animals and improving the comfort of the animals in the accommodation space 11.

[0033] The circulating fan 50 and the heating assembly 30 are arranged in the third section 213, the circulating fan 50 is arranged below the heating assembly 30, and the evaporator 42 is arranged in the second section 212. The circulating fan 50 and the heating assembly 30 are arranged in the third section 213 with a smaller cross-sectional area, which can reduce the possibility of being touched by users or animals. In addition, in order to uniformly heat the air, when arranged, a plurality of heating assemblies 30 should be laid along the cross section of the third section 213 to reduce the dead angle of heating as much as possible. Therefore, if the cross section of the third section 213 is small, the number of heating assemblies 30 can be reduced to a certain extent, thereby reducing the cost. In addition, the reduction of the cross-sectional area of the third section 213 also leaves a certain space for arranging other devices (such as the condenser fan 44, the compressor 43, the condenser 41, etc.), thereby making the overall structure more compact. The cross-sectional area of the second section 212 is large, which can be used to place a larger area evaporator 42. The larger the area of the evaporator 42, the faster the cooling rate can be achieved. In addition, the air speed of the first section 211 is low, which can also avoid the entry of hair into the air duct 21 to a certain extent.

[0034] A water tank 24 is arranged below the evaporator 42. When the evaporator 42 absorbs heat from the air, the water vapor in the air will condense into liquid and accumulate on the surface of the evaporator 42. When the accumulated water reaches a certain amount, the condensed water will be left. Therefore, the water tank 24 arranged below the evaporator 42 can be used to collect the condensed water.

[0035] The first air inlet 22 of the first section 211 and the second air inlet 23 of the second section 212 are provided with detachable filter members 25, and a mistaken touch prevention partition 26 is arranged between the first section 211 and the third section 213. When the air in the accommodation space 11 enters the first air inlet 22, it is possible to carry animal hair or other objects into the air duct 21, so the filter members 25 can improve the above phenomenon. In addition, the filter members 25 can be dust covers or dust gauze plates, which can also play the role of uniform air distribution. The filter members 25 are detachably arranged in the first air inlet 22 and the second air inlet 23, which can facilitate replacement or facilitate cleaning after being detached. The mistaken touch prevention partition 26 can prevent the user from touching the heating assembly 30 or the circulating fan 50 when the filter members 25 are detached. The mistaken touch prevention partition 26 can be a mesh structure or have a hollow structure to allow gas to pass through the mistaken touch prevention partition 26 into the third section 213.

[0036] The animal monitoring cage 1 further comprises a first temperature sensor 31 and a second temperature sensor 32 coupled with the control module 60. The first temperature sensor 31 is arranged in the first section 211. The second temperature sensor 32 is arranged in the second section 212. If the first temperature sensor 31 is placed in the animal accommodation cage 10, it may cause the animal to be touched, resulting in inaccurate temperature measurement or damage. The air temperature entering the first section 211 through the first air inlet 22 under the action of the circulating fan 50 is approximately the same as the temperature in the animal accommodation cage 10, so the temperature collected by the first temperature sensor 31 arranged in the first air duct 21 can also be used to represent the temperature in the animal accommodation cage 10, thereby providing relatively accurate feedback information for the control module 60.

[0037] The animal monitoring cage 1 can further comprise a humidity sensor 71 to detect humidity. The humidity sensor 71 is arranged in the first section 211. The accuracy of the operation of the humidity sensor 71 is affected by the wind speed. The wind speed in the third section 213 is relatively fast due to the small cross-sectional area, while the wind speed in the animal accommodation cage 10 is relatively small. Therefore, arranging the humidity sensor 71 in the first section 211 can more accurately represent the humidity information, and also can avoid the animal from contacting the humidity sensor 71.

[0038]

Temperature control scheme

[0039] Referring to Figure 2 and Figure 3The air duct 21 includes a first air inlet 22 and a second air inlet 23 which are in communication with the accommodation space 11. The circulating fan 50 is configured to drive the air in the accommodation space 11 to enter the air duct 21 through the first air inlet 22 and return to the accommodation space 11 through the second air inlet 23. It is to be explained that the circulating fan 50 can be a one-way fan to drive the air to enter the air duct 21 through the first air inlet 22. Of course, the circulating fan 50 can also be a two-way fan to adjust its forward rotation or reverse rotation according to different needs.

[0040] The animal monitoring cabin 1 can further include a first temperature sensor 31 and a second temperature sensor 32 coupled with the control module 60. The first temperature sensor 31 and the second temperature sensor 32 are respectively used to monitor the inlet air temperature of the first air inlet 22 and the outlet air temperature of the second air inlet 23. Since the air in the accommodation space 11 has not been heated or cooled when entering the first air inlet 22, the inlet air temperature detected by the first temperature sensor 31 can be used to represent the current temperature in the accommodation space 11.

[0041] The control module 60 controls at least one of the heating power of the heating assembly 30 and the refrigeration power of the refrigeration assembly 40 based on the inlet air temperature detected by the first temperature sensor 31 and the outlet air temperature detected by the second temperature sensor 32, so as to adjust the temperature in the accommodation space 11. For example, if it is necessary to increase the air temperature in the accommodation space 11, the adjustment can be performed by increasing the heating power while maintaining the refrigeration power unchanged, or by increasing the heating power and reducing the refrigeration power.

[0042] The heating assembly 30 includes a plurality of PTC heaters, and the control module 60 adjusts the heating power by controlling the duty cycle (i.e. the ratio of heating time to total working time) of the PTC heaters and / or the number of PTC heaters in the heating state. Of course, the heating assembly 30 can also include a plurality of resistance wires, and the control module 60 can adjust the heating power by controlling the current or the number of resistance wire lines in the heating state.

[0043] When the compressor 43 of the refrigeration assembly 40 is adjustable in rotation speed, the control module 60 can adjust the refrigeration power of the compressor 43 by controlling the rotation speed of the compressor 43. Of course, the power of the refrigeration assembly 40 can also be maintained unchanged, and the temperature rise can be controlled by controlling the heating power of the heating assembly 30 to be greater than the refrigeration power, and the temperature drop can be controlled by controlling the heating power of the heating assembly 30 to be less than the refrigeration power.

[0044] The control module 60 can obtain the inlet air temperature detected by the first temperature sensor 31 and the target temperature, and determine whether the difference between the inlet air temperature and the target temperature is greater than a first threshold value,

[0045] If the result of the judgment is yes, it is further judged whether the inlet air temperature is greater than the target temperature, if the result of the judgment is yes, the heating assembly 30 is controlled to operate at the first heating power, if the result of the judgment is no, the heating assembly 30 is controlled to operate at the second heating power;

[0046] If the result of the judgment is no, the heating assembly 30 is controlled to operate at the third heating power.

[0047] The target temperature can be a temperature input by a user, that is, a temperature that the user expects the accommodation space 11 to finally reach. The difference between the inlet air temperature and the target temperature refers to the absolute value. The first heating power can be greater than the second heating power. The first heating power can be the maximum heating power. The second heating power can be 0. The third heating power can be a preset heating power and can match the target temperature.

[0048] For example, the animal monitoring cage 1 has multiple temperature ranges, each of which has a corresponding third heating power. For example, the multiple temperature ranges can be [15, 17.5), [17.5, 22.5), [22.5, 27.5), [27.5, 32.5), [32.5, 37.5), [37.5, 40). The third heating powers corresponding to the above six temperature ranges are 55% of the maximum heating power, 60% of the maximum heating power, 61% of the maximum heating power, 63% of the maximum heating power, 65% of the maximum heating power, and 70% of the maximum heating power, respectively. Of course, the temperature ranges can also be set as needed.

[0049] The control module 60 can obtain the target temperature input by the user, judge the temperature range corresponding to the target temperature, and obtain the third heating power corresponding to the temperature range. The user can input the target temperature through an interactive device (such as a touch screen or a keyboard). For example, when the user inputs 30 degrees, it can be judged that it belongs to the temperature range [27.5, 32.5), and the corresponding third heating power is 65% of the maximum heating power.

[0050] That is, when the inlet air temperature and the target temperature have a large difference, the heating assembly 30 can be controlled to operate at a higher / lower heating power to quickly adjust the temperature. When the inlet air temperature and the target temperature have a small difference, the temperature can be maintained constant at a power matching the target temperature.

[0051] However, this scheme also has problems, for example, 15 and 16 degrees belong to the same range [15, 17.5) at the same time, but the matching heating powers of the two temperature requirements can also have differences, and the common use of the same third heating power can cause large temperature fluctuations.

[0052] Therefore, the control module 60 can also obtain a target outlet air temperature, determine whether a difference between the outlet air temperature and the target outlet air temperature is greater than a first threshold, and if the determination is yes, then fine tune the third heating power, and if the determination is no, then maintain the current heating power.

[0053] The target outlet air temperature can be obtained by a target temperature input by a user, and an average difference between an actual outlet air temperature and an actual inlet air temperature in a past preset time range. Since the target temperature is close to the actual inlet air temperature, the difference between the actual outlet air temperature and the actual inlet air temperature is close to the difference between the actual outlet air temperature and the target temperature. The target temperature plus the difference can approximately calculate the outlet air temperature (i.e. the target outlet air temperature) required when the average temperature in the accommodation space 11 reaches the target temperature. The average difference between the actual inlet air temperature and the actual outlet air temperature can exist some differences under different temperatures and different environments. Therefore, the preset time range can be within the past 10 minutes, so that more real-time data can be collected.

[0054] The fine tuning of the third heating power can include: if the outlet air temperature is greater than the target outlet air temperature, then controlling to reduce the third heating power; and if the outlet air temperature is less than the target outlet air temperature, then increasing the third heating power. For example, the third heating power can be increased by 1% of the maximum heating power or decreased by 1% of the maximum heating power.

[0055] The current heating power refers to the heating power when the difference between the outlet air temperature and the target outlet air temperature is less than or equal to the first threshold, which can be the third heating power, or the heating power after fine tuning based on the third heating power. The control module 60 can collect the outlet air temperature in real time or at a fixed time, and perform the above steps.

[0056] The present inventors have found that using the actual outlet air temperature and the target outlet air temperature as feedback signals can greatly reduce temperature fluctuations in the temperature adjustment process. However, using the general inlet air temperature and the target temperature as feedback signals can cause huge temperature fluctuations. This is because the target outlet air temperature is more affected by the heating device and the cooling device, and is easier to control, while the inlet air temperature is not only affected by the heating device and the cooling device, but also affected by the volume of the accommodation space 11, and the size and physiological state of the animals in the accommodation space 11.

[0057]

Humidity control scheme

[0058] The animal monitoring enclosure 1 also includes a humidifier 70, which is arranged outside or inside the animal accommodation enclosure 10. The humidifier 70 can be used to increase moisture in the accommodation space 11, thereby controlling humidity. The animal monitoring enclosure 1 can also include a humidity sensor 71 to detect humidity.

[0059] The control module 60 can be coupled to the humidity sensor 71 to obtain a current humidity, and determine whether the current humidity is less than a first target humidity. If the determination is yes, a humidification operation is performed. If the determination is no, it is determined whether the current humidity is greater than a second target humidity. If the determination is yes, a dehumidification operation is performed. The second target humidity is not less than the first target humidity.

[0060] The humidification operation includes at least one of controlling the humidifier 70 to start, increasing a rotation speed of the circulating fan 50, reducing a frequency of the compressor 43, and reducing a rotation speed of the condensing fan 44 of the refrigeration assembly 40. Controlling the humidifier 70 to start can directly increase the supply of water vapor, thereby increasing the humidity. Increasing the rotation speed of the circulating fan 50 can reduce the residence time of air in the vicinity of the evaporator 42. When the air and the evaporator 42 are in contact for a short time, the water vapor can not be sufficiently cooled and condensed, thereby inhibiting the decrease in humidity. Reducing the frequency of the compressor 43 or reducing the rotation speed of the condensing fan 44 can also inhibit the decrease in humidity to some extent.

[0061] Conversely, the dehumidification operation includes at least one of turning off the humidifier 70, reducing the rotation speed of the circulating fan 50, increasing the frequency of the compressor 43, and increasing the rotation speed of the condensing fan 44 of the refrigeration assembly 40.

[0062] Finally, it should be noted that the above embodiments are mainly used to illustrate the technical solutions of the present application, and should not be understood as a limitation of the present application; the above embodiments have been described in detail and specifically, and a person of ordinary skill in the art can modify the technical solutions described in the above embodiments, or replace some or all of the technical features; and these modifications or replacements cannot make the corresponding technical solutions and the technical solutions of the present application constitute different inventions, and thus should be covered in the scope of the claims and the specification of the present application. In particular, in the absence of structural conflicts or combination barriers, each technical feature mentioned in each embodiment can be combined in any way, and the technical solutions formed after the combination should not essentially be considered as deviating from the scope of the technical solutions of the present application.
