[0002] The animal monitoring cabin can provide an adaptive environment for animals and is widely used in postoperative recovery, intensive care and other scenarios of animals. Generally, the animal monitoring cabin also needs to be designed with an emergency ventilation port to deal with various accidents.

[0003] However, the current emergency ventilation port is generally arranged in the air duct assembly, and the emergency ventilation port needs to be indirectly connected between the air duct assembly and the animal-containing space, which means that when the emergency ventilation is performed, the air from the outside needs to move a long path to reach the inside of the animal-containing space. Although the animal monitoring cabin can be ventilated in emergency, the ventilation efficiency is very low. Due to the relatively closed environment inside the animal-containing space, the low ventilation efficiency may also lead to high carbon dioxide concentration and low oxygen concentration, thereby causing suffocation of the animals.

[0035] The animal monitoring cabin 1 is a device commonly used in the scene of postoperative recovery of animals, intensive care, etc., and generally has functions of temperature control, humidity control, oxygen concentration control, carbon dioxide concentration control, etc. Generally speaking, the animal monitoring cabin 1 also has an emergency ventilation function to avoid accidents such as suffocation of animals inside the animal monitoring cabin 1 when the animal monitoring cabin 1 is powered off.
[0036] Referring to Figure 1 , the animal monitoring cabin 1 generally includes an animal containing cabin 10 and an air duct assembly 20. The air duct assembly 20 is arranged in the animal containing cabin 10 and communicates with the animal containing space inside the inner container 11. The air duct assembly 20 is internally provided with a heating unit and a refrigeration unit. The air duct assembly 20 can be one air duct, and the heating unit and the refrigeration unit are arranged in the same air duct. The air duct assembly 20 can also include a heating air duct with a heating unit and a refrigeration air duct with a refrigeration unit.
[0037] Referring again to Figure 1 , the present application opens the emergency ventilation port 12 on the animal containing cabin 10, so that the emergency ventilation port 12 is closer to the animals in the containing space, shortens the distance of outside air entering the containing space during emergency ventilation, and thus improves the efficiency of air exchange.
[0038] As Figure 1 and Figure 3The animal containment cabin 1 with the emergency ventilation device 30 comprises an animal containment cabin 10 and an emergency ventilation device 30. The animal containment cabin 10 has an inner container 11 for containing animals, and the inner container 11 is provided with an emergency ventilation opening 12. The emergency ventilation device 30 is arranged on the animal containment cabin 10 and is configured to switch to a first state when a first signal is received and to switch to a second state when a second signal is received. In the first state, the emergency ventilation device 30 closes the emergency ventilation opening 12, and in the second state, the emergency ventilation device 30 opens the emergency ventilation opening 12.
[0039] Generally, the emergency ventilation device 30 can be in the first state to make the animal containment cabin 1 as closed as possible, which is more conducive to temperature control and humidity control. When the animal containment cabin 1 is powered off or other unexpected events occur, the emergency ventilation device 30 can be switched to the second state to connect the animal containment cabin 10 to the outside world to avoid suffocation or oxygen deficiency of the animals. The emergency ventilation opening 12 is provided on the inner container 11, which greatly reduces the difficulty of air exchange between the outside and the inner container 11 when the emergency ventilation opening 12 is opened, thereby improving the efficiency of air exchange between the inner container 11 and the outside.
[0040] The emergency ventilation opening 12 is provided on the side wall of the inner container 11 and located at the middle part of the side wall. The emergency ventilation opening 12 is arranged at the middle part of the side wall, which can be closer to the animals and avoid being blocked by the thermal insulation pad and the animals. At the same time, the emergency ventilation opening 12 arranged at the middle part can also adapt to animals of different sizes. For example, the distance between the emergency ventilation opening 12 and the bottom wall can be greater than 10 cm and less than 50 cm. The distance between the emergency ventilation opening 12 and the remaining side walls can be greater than 10 cm.
[0041] The emergency ventilation opening 12 can comprise a plurality of arrayed air holes 120. The air holes 120 are provided on the inner container 11. The arrayed air holes 120 form the structure of the emergency ventilation opening 12, and the part of the emergency ventilation opening 12 without holes can limit the ventilation opening shutter 32 (to be described later) from entering the inner container 11 accidentally. In addition, this structure can reduce the risk of the animals getting their heads stuck in the emergency ventilation opening 12 when the emergency ventilation opening 12 is opened. The diameter of the air holes 120 can be 1 mm to 10 mm. The inner container 11 can be formed by welding sheet metal parts, and the arrayed air holes 120 can be integrally punched on the sheet metal parts, which can reduce the manufacturing and assembly processes.
[0042] Referring to Figure 2The animal monitoring cabin 1 can further comprise a power module 40, a control module 50 and a voltage regulating circuit 45. The power module 40 can supply power to the control module 50. The voltage regulating circuit 45 is coupled to the power module 40, the control module 50 and the emergency ventilation device 30, and is configured to output a first signal or a second signal to the emergency ventilation device 30 under the control of the control module 50.
[0043] wherein, the first signal and the second signal can also be referred to as a first voltage signal and a second voltage signal. The second signal can be a low-level signal. In this way, the emergency ventilation device 30 can not only actively receive the low-level signal output by the voltage regulating circuit 45 controlled by the control module 50, but also receive the low-level signal when the animal monitoring cabin 1 is powered off, so as to switch to the second state. In this case, the animal monitoring cabin 1 can have the functions of active emergency ventilation and automatic emergency ventilation after power failure at the same time.
[0044] The voltage regulating circuit 45 can include one or more of a voltage conversion circuit (such as a DC-DC circuit), a switching circuit and the like. If the voltage regulating circuit 45 is a switching circuit, when the control module 50 controls the switching circuit to be turned on, the switching circuit can output a high level (first signal), and when the control module 50 controls the switching circuit to be turned off, the switching circuit can output a low level (second signal). If the voltage regulating circuit 45 is a voltage conversion circuit, the voltage conversion circuit can also output high and low levels (first signal and second signal) under the control of the control module 50.
[0045] Of course, the situation that requires to start the emergency ventilation is not limited to the power failure of the animal monitoring cabin 1, for example, the carbon dioxide absorption device is not replaced in time, the carbon dioxide absorption device fails, the oxygen generator is not connected, the oxygen generator pipeline is blocked, etc. In these cases, the animal monitoring cabin 1 also needs to have the function of active emergency ventilation.
[0046] Therefore, the animal containment cabin 10 can also be provided with an oxygen concentration detection device 13 and / or a carbon dioxide concentration detection device 14 coupled to the control module 50. The oxygen concentration detection device 13 can be used to detect the current oxygen concentration. The carbon dioxide concentration detection device 14 can be used to detect the current carbon dioxide concentration. The control module 50 can obtain the current oxygen concentration or the current carbon dioxide concentration, and control the emergency ventilation device 30 to switch to the second state when the current oxygen concentration is too high or the carbon dioxide concentration is too low.
[0047] Specifically, the control module 50 can obtain the current oxygen concentration collected by the oxygen concentration detection device 13, and determine whether the current oxygen concentration is less than a preset oxygen concentration. If the determination result is yes, the control module 50 controls the voltage regulating circuit 45 to output the second signal, and further controls the emergency ventilation device 30 to switch to the second state.
[0048] Likewise, the control module 50 can acquire the current carbon dioxide concentration collected by the carbon dioxide concentration detection device 14, determine whether the current carbon dioxide concentration is greater than the preset carbon dioxide concentration, and if the determination result is yes, control the voltage regulation circuit 45 to output a second signal, and further control the emergency ventilation device 30 to switch to the second state.
[0049] Of course, the control module 50 can also have other functions, for example, coupled with the oxygen concentration detection device 13 and / or the carbon dioxide concentration detection device 14 to acquire the current oxygen concentration and / or the current carbon dioxide concentration, and further alarm when the oxygen concentration is too low or the carbon dioxide concentration is too high to prompt the user.
[0050] In addition, considering that the animal monitoring cabin 1 has an active emergency ventilation function, the emergency ventilation device 30 can still switch to the second state and open the emergency ventilation port 12. If the emergency ventilation port 12 and the air outlet of the air duct assembly 20 are arranged face to face, the air output by the air duct assembly 20 can not circulate inside the accommodation space, but directly flow from the emergency ventilation port 12 to the outside, which can cause the temperature inside the animal monitoring cabin 1 to fluctuate greatly. Therefore, the emergency ventilation port 12 should be arranged as much as possible in the dead angle of the air circulation of the air duct assembly 20, so that the air output by the air duct assembly 20 can at least circulate in the animal accommodation cabin 10. For example, the emergency ventilation device 30 and the air duct assembly 20 can be arranged on adjacent side walls (see Figure 1 Of course, it is also feasible to arrange the emergency ventilation device 30 and the air duct assembly 20 on the same side wall.
[0051] Referring to Figure 3 , the emergency ventilation device 30 can include an actuator 31 and a ventilation port shutter 32. The ventilation port shutter 32 is arranged on the actuator 31. When the emergency ventilation device 30 switches from the second state to the first state, the actuator 31 pushes the ventilation port shutter 32 to close and block the emergency ventilation port 12. When the emergency ventilation device 30 switches from the first state to the second state, the actuator 31 pushes the ventilation port shutter 32 away from the emergency ventilation port 12.
[0052] The ventilation port shutter 32 can be an acrylic plate or a metal plate. The actuator 31 can include at least one of a motor, an electromagnet, or an air cylinder, which can push the ventilation port shutter 32 to move upon receiving different signals.
[0053] In one specific embodiment, the actuator 31 can include a support 311 and a push-pull electromagnet 312. The support 311 is arranged on the inner container 11 and is used to support the push-pull electromagnet 312, which is used to push the vent baffle 32. The support 311 can be a connecting plate. The push-pull electromagnet 312 can be a push electromagnet, a pull electromagnet, and a through-type push-pull electromagnet.
[0054] The push-pull electromagnet 312 generally includes a coil, a core, and an armature. The coil is generally wound by an insulated wire (such as enameled copper wire). When an electric current passes through the coil, a magnetic field is generated. The core is usually made of soft magnetic material, such as electrical pure iron. The core can be magnetized under the action of the magnetic field generated by the coil to enhance the magnetic field strength of the electromagnet. The armature is the part that interacts with the core. When the coil is energized, the armature will move towards the core (pull electromagnet) or away from the core (push electromagnet) under the action of the magnetic force, thereby realizing the action of pushing or pulling. Of course, some push-pull electromagnets 312 also include elastic components such as springs. Taking the push electromagnet as an example, the armature will be attracted to the core under the action of the magnetic force when the coil is energized, and the armature needs to be reset away from the core under the action of the spring when the coil is de-energized. Of course, the spring can be replaced by other means to reset the armature, for example, by gravity or other external forces.
[0055] In one specific embodiment, the control module 50 can be coupled to the oxygen concentration detection device 13 and the carbon dioxide concentration detection device 14 to obtain the current oxygen concentration and the current carbon dioxide concentration. If the current oxygen concentration is less than the preset oxygen concentration or the current carbon dioxide concentration is greater than the preset carbon dioxide concentration, the control voltage regulation circuit 45 outputs a second signal to make the emergency ventilation device 30 switch to the second state to open the emergency vent 12. If the current oxygen concentration is greater than the preset oxygen concentration or the current carbon dioxide concentration is less than the preset carbon dioxide concentration, the control voltage regulation circuit 45 outputs a first signal to make the emergency ventilation device 30 switch to the first state to close the emergency vent 12.
[0056] When the actuator 31 of the emergency ventilation device 30 includes a push-pull electromagnet 312, the coil will heat very seriously if the emergency ventilation device 30 receives the first signal for a long time, and the overall power consumption of the emergency ventilation device 30 will be very high.
[0057] Based on this, the control module 50 can also be configured to: after the control voltage regulation circuit 45 outputs the first signal to make the emergency ventilation device 30 switch to the first state, the control voltage regulation circuit 45 outputs a third (voltage) signal smaller than the first (voltage) signal to reduce the power of the emergency ventilation device 30. The voltage of the third signal can be smaller than the voltage of the first signal. For example, the first signal can be a 15V voltage, and the third signal can be a 12V voltage. In this way, the power of the emergency ventilation device 30 and the heat of the coil can be reduced while keeping the emergency ventilation device 30 in the first state. That is, when the emergency ventilation device 30 needs to switch to the first state to close the emergency ventilation port 12, the first signal with a higher level can be accepted first to make the push-pull electromagnet perform a push / pull action, so that the ventilation port shutter 32 closes the emergency ventilation port, and then the third signal with a lower level is accepted to maintain the state of the push-pull electromagnet.
[0058] In addition, even though the direct arrangement of the emergency ventilation port 12 on the inner container 11 improves the efficiency of air exchange, experiments have shown that the carbon dioxide concentration in the animal containment cabin 10 can continue to rise for some large pets (such as large dogs). That is, even with passive emergency ventilation, some large pets can still have accidents.
[0059] Therefore, the emergency ventilation device 30 can also include an active air exchange fan 60 arranged near the emergency ventilation port 12. The active air exchange fan 60 is used to start to accelerate air circulation when the emergency ventilation device 30 is in the second state. The control module 50 can be coupled to the active air exchange fan 60. The power supply module 40 can be coupled to the active air exchange fan 60 to supply power to the active air exchange fan 60. The active air exchange fan 60 can be arranged opposite to the emergency ventilation port 12, which can improve the efficiency of air exchange.
[0060] Further, the active air exchange fan 60 is a bidirectional fan. In this way, when the oxygen concentration is too low, the active air exchange fan 60 rotates forward to make fresh air from the outside enter the animal containment cabin 10, and when the carbon dioxide concentration is too high, the active air exchange fan 60 rotates reversely to suck out the dirty air from the animal containment cabin 10.
[0061] That is, the control module 50 can obtain the current oxygen concentration, determine whether the current oxygen concentration is less than the preset oxygen concentration, and if the determination result is yes, control the active air exchange fan 60 to rotate forward. Similarly, the control module 50 can obtain the current carbon dioxide concentration, determine whether the current carbon dioxide concentration is greater than the preset carbon dioxide concentration, and if the determination result is no, control the active air exchange fan 60 to rotate reversely.
[0062] The active air exchange fan 60 can only work when the animal care cabin 1 is connected to the external power supply, and if the animal care cabin 1 is powered off, the active air exchange fan 60 cannot be started due to power failure. Therefore, the power module 40 can include an energy storage battery 41, which is charged when the animal care cabin 1 is connected to the external power supply and discharged when the external power supply is disconnected. In this way, when the animal care cabin 1 is powered off (not connected to the external power supply), the energy storage battery 41 can supply power to the active air exchange fan 60 to ensure that the active air exchange fan 60 can work normally.
[0063] 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 foregoing 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 foregoing embodiments, or replace part 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. Especially, in the absence of structural conflicts or combination barriers, the technical features mentioned in each embodiment can be combined in any way, and these combinations still essentially should not be considered as deviating from the scope of the technical solutions of the present application.
