Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment calibration, in particular to a temperature and humidity integrated calibration device for an infant incubator. BACKGROUND

[0002] An infant incubator is a critical medical device in neonatal care, and the temperature and humidity of its internal environment have a direct impact on the healthy development of infants. Therefore, regular accurate calibration of the temperature and humidity in the infant incubator is a necessary link to ensure its safe and effective operation.

[0003] However, conventional calibration devices usually require sensors or probes to be connected by wires into the incubator, which often requires opening or damaging the sealing structure of the incubator, resulting in contamination of the sterile environment inside the incubator, thereby increasing the risk of cross-infection of newborns. If the calibration device itself cannot be thoroughly disinfected or is not thoroughly disinfected, the bacteria and pathogens it brings will pose a serious threat to the health of infants.

[0004] And the existing device, when detecting, the sensor is in contact with the static air, or only through a simple fan for local air circulation, which makes it difficult for the sensor to accurately reflect the real temperature and humidity distribution of the overall environment in the incubator, resulting in inaccurate detection results, especially in the presence of temperature or humidity gradients SUMMARY

[0005] The technical problem to be solved by the present application is that the existing infant incubator temperature and humidity calibration device has the disadvantages of damaging the airtightness, low detection accuracy, inconvenient disinfection, and safety hazards. Therefore, we propose a temperature and humidity integrated calibration device for an infant incubator.

[0006] To achieve the above purpose, the present application adopts the following technical scheme: a temperature and humidity integrated calibration device for an infant incubator, comprising an external host and an internal sterile detection disc, the external host is detachably attached to the outside of the incubator cover, and the internal sterile detection disc is detachably attached to the inside of the incubator cover, and the two are coaxially positioned and fixed by magnetic attraction;

[0007] The external host includes a host lower shell and an operation panel, the host lower shell coaxially has a ring-shaped first induction coil, a drive motor and a host circuit board, the drive motor is fixedly connected with the host lower shell coaxially, the output shaft of the drive motor extends along the direction towards the incubator cover and is fixedly connected with a first magnetic coupling disc, and the operation panel is electrically connected with the host circuit board;

[0008] The built-in sterile detection disc is a sealed cavity structure, comprising a detection disc arc-shaped cover and a detection disc bottom plate which are detachably and claspably connected, a detection well is formed in the center of the detection disc arc-shaped cover, and the detection well is completely sealed and isolated from the internal sealed cavity of the sterile detection disc;

[0009] A second induction coil is coaxially fixed on the detection disc bottom plate, an annular circuit board is arranged above the second induction coil, and the second induction coil and the annular circuit board are electrically connected and arranged around the detection well;

[0010] Temperature sensors and humidity sensors are embedded in the inner side wall of the detection well, and the temperature sensors and the humidity sensors are electrically connected with the annular circuit board;

[0011] A second magnetic coupling disc is rotationally connected to the bottom of the detection well through a bearing, the second magnetic coupling disc is coaxially arranged with the first magnetic coupling disc and magnetically attracted, and a driving rod is coaxially fixedly connected to the upper end surface of the second magnetic coupling disc;

[0012] A first lifting tower is axially and slidingly connected in the detection well, an array of air outlets is formed in the side wall of the first lifting tower, a centrifugal fan is coaxially and rotationally connected in the first lifting tower, a through air inlet through hole is formed in the center of the centrifugal fan, the driving rod penetrates through the air inlet through hole and forms a circumferential limiting and axial sliding fit with the centrifugal fan;

[0013] A central hole extending in the axial direction is formed in the center of the first lifting tower, a second lifting tower is axially and slidingly connected in the central hole, a plurality of air inlets are formed in the side wall of the second lifting tower, a threaded rod is coaxially and fixedly connected to the lower end surface of the second lifting tower, a threaded hole adapted to the threaded rod is formed in the center of the driving rod in the axial direction, and the threaded rod is threadedly engaged with the threaded hole;

[0015] The external host and the built-in sterile detection disc are magnetically attracted and positioned, contactless installation and fixation are realized, and the sealing property of the infant incubator is not damaged; the wireless power supply and data transmission are completed by using electromagnetic induction coupling technology, and the pollution risk caused by wired connection is avoided; the built-in sealed cavity structure guarantees the sterility of the detection disc, and the detection disc can be soaked and disinfected as a whole; the air circulation channel is formed by the driving rod, the first lifting tower, the second lifting tower and the centrifugal fan, so that the temperature and humidity sensors are in full contact with the flowing air, and the detection accuracy is improved; the operation panel displays the data in real time, meets the convenient detection requirement, and the overall structure meets the safe use requirement of the infant incubator.

[0016] Further, the main machine lower shell and the operation panel are detachably connected, the main machine circuit board is fixed in the main machine lower shell and is electrically connected with the first induction coil and the driving motor.

[0017] The detachable design of the main machine lower shell and the operation panel facilitates the maintenance and repair of the internal circuit board, induction coil and other components; the stable electrical connection of the circuit board with the first induction coil and the driving motor ensures the reliability of power transmission and power driving, and ensures the collaborative operation of the various functional modules of the external main machine.

[0018] Further, the outer side wall of the driving rod is integrally formed with a plurality of first sliding limiting strips extending in the axial direction, and the inner wall of the air inlet through hole of the centrifugal fan is provided with an axial sliding groove matched with the first sliding limiting strips, the first sliding limiting strips and the axial sliding groove are in sliding fit, and the circumferential limiting of the driving rod and the centrifugal fan is realized.

[0019] Through the matching of the first sliding limiting strips and the axial sliding groove, the relative rotation of the driving rod and the centrifugal fan in the circumferential direction is limited, while the axial relative sliding of the two is allowed, so that the driving rod can drive the centrifugal fan to rotate synchronously when the driving rod rotates, air circulation driving is realized, and the axial lifting action of the lifting tower is not affected, the stability and motion coordination of the transmission structure are ensured.

[0020] Further, the outer side wall of the first lifting tower is integrally formed with a plurality of second sliding limiting strips extending in the axial direction, and the inner side wall of the detection well is provided with an axial limiting groove matched with the second sliding limiting strips, the second sliding limiting strips and the axial limiting groove are in sliding fit, and the circumferential rotation of the first lifting tower is limited.

[0021] Through the sliding fit of the second sliding limiting strips and the axial limiting groove, the first lifting tower can only lift in the axial direction, avoiding synchronous rotation with the driving rod, ensuring that the threaded rod and the driving rod can accurately convert the threaded engagement transmission into the lifting action of the first lifting tower, realizing the stable opening and closing of the air outlet, and ensuring the normal switching of the air circulation channel.

[0022] Further, the outer side wall of the second lifting tower is integrally formed with a plurality of third sliding limiting strips extending in the axial direction, and the inner side wall of the central hole is provided with an axial limiting groove matched with the third sliding limiting strips, the third sliding limiting strips and the axial limiting groove are in sliding fit, and the circumferential rotation of the second lifting tower is limited.

[0023] Through the matching of the third sliding limiting strips and the axial limiting groove, the circumferential rotation of the second lifting tower is limited, so that it can only slide in the axial direction along the central hole of the first lifting tower, ensuring that the threaded rod drives the second lifting tower to accurately lift under the threaded transmission, realizing the synchronous opening and closing of the air inlet, and forming a complete air circulation path with the air outlet.

[0024] Furthermore, a first return spring is sleeved on the outer side of the first lifting tower, and an annular limiting edge is integrally formed on the lower end face of the first lifting tower. The first return spring abuts against the annular limiting edge and the upper end face of the arc-shaped cover of the detection plate, and is always in a compressed state, providing axial return elastic force for the first lifting tower.

[0025] The first return spring in the compressed state continuously provides axial return force. When the device stops working, it can drive the first lifting tower to automatically fall back to the initial position, close the air outlet, and maintain the sealed environment of the detection well. This facilitates subsequent disinfection and storage, and also prevents impurities from entering the detection well and affecting the accuracy of the sensor when not in operation.

[0026] Furthermore, a second return spring is fitted on the outer side of the second lifting tower, and an annular limiting edge is integrally formed on the lower end face of the second lifting tower. The second return spring abuts against the annular limiting edge and the upper end face of the first lifting tower, and is always in a compressed state, providing axial return elastic force for the second lifting tower.

[0027] The compression design of the second reset spring is linked with the first reset spring. After the device stops, it can drive the second lifting tower to fall back synchronously to close the air inlet, further enhancing the sealing effect of the detection well, ensuring a sterile environment inside the detection panel, and preventing moisture and impurities from entering and damaging the internal circuits or sensors.

[0028] Furthermore, an annular sealing gasket is provided between the arc-shaped cover of the testing tray and the bottom plate of the testing tray; an annular rubber gasket is provided between the first lifting tower and the opening end of the testing well; and an annular rubber gasket is provided between the second lifting tower and the upper opening of the central hole, thereby forming a waterproof seal in the internal sealed chamber of the sterile testing tray.

[0029] The installation of multiple sealing gaskets and rubber pads creates a high-strength waterproof sealing structure with an IP67 rating or higher, ensuring that the internal circuits, coils, and other components of the sterile testing tray are completely isolated from the outside. It can be directly immersed in alcohol or disinfectant for disinfection, meeting the sterility requirements of infant incubators, while preventing moisture from seeping into the incubator and damaging electronic components.

[0030] Furthermore, the air outlets are evenly distributed around the side wall of the first lifting tower, and the opening direction of the air outlets is inclined outward in the radial direction; the air inlets are evenly distributed around the side wall of the second lifting tower, and the opening direction of the air inlets is inclined in the radial direction.

[0031] The air outlets are evenly distributed circumferentially and tilted radially outward, allowing the exhausted air to diffuse evenly into the incubator and avoiding localized airflow concentration. The air inlets are circumferentially distributed and tilted radially inward, efficiently drawing in air from the incubator. Together, they form a stable and uniform air circulation field, ensuring that the temperature and humidity sensors detect accurate data of the overall environment inside the incubator, thus improving the accuracy and representativeness of the test results.

[0032] Furthermore, both the first and second magnetic coupling disks are neodymium iron boron permanent magnets, with opposite magnetic poles on their opposing surfaces. The first and second magnetic coupling disks are composed of multiple sector-shaped regions joined together, with adjacent regions having opposite magnetic pole directions, thus forming a coupling.

[0033] The coupling disk is made of neodymium iron boron permanent magnet with high magnetic force to ensure the magnetic attraction strength between the external host and the built-in detection disk, so as to achieve stable positioning. The design of opposite magnetic poles on opposite surfaces and opposite magnetic poles on adjacent fan-shaped areas enhances the magnetic coupling effect, improves the power transmission efficiency, and enables the rotational power of the drive motor to be accurately and stably transmitted to the drive rod of the built-in detection disk. At the same time, the non-contact transmission method avoids damage to the sealing of the detection disk.

[0034] The technical effects and advantages of this invention are as follows:

[0035] 1. This invention achieves contactless installation and fixation by magnetically engaging and positioning the external host with the built-in sterile detection tray. This eliminates the need to damage the sealed structure of the infant incubator, preventing the intrusion of bacteria or pathogens, greatly reducing the risk of cross-infection, and ensuring the health and safety of newborns. Furthermore, this invention uses electromagnetic induction coupling technology to achieve wireless power supply and data transmission, eliminating the pollution risks and operational obstacles associated with wired connections. The built-in detection tray contains no dangerous devices such as batteries and can be completely immersed for disinfection. It is convenient to operate and highly safe.

[0036] 2. Through the ingenious design of the drive rod, the first lifting tower, the second lifting tower, and the centrifugal fan, this invention forms a highly efficient and stable air circulation channel. The temperature and humidity sensor is in full contact with the constantly flowing air, which can reflect the real temperature and humidity of the overall environment inside the incubator in real time and accurately. Compared with traditional static contact, it significantly improves the detection accuracy and the representativeness of the data. Attached Figure Description

[0048] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of this application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. It should be noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0049] Example 1, refer to Figures 1 to 9 This invention provides an integrated temperature and humidity calibration device for an infant incubator, comprising an external main unit 1 and a built-in sterile detection tray 2. The external main unit 1 is detachably attached to the outside of the infant incubator lid, and the built-in sterile detection tray 2 is detachably attached to the inside of the infant incubator lid. The two are coaxially positioned and fixed by the magnetic attraction of a first magnetic coupling plate 7 and a second magnetic coupling plate 16. This contactless installation method ensures that the airtightness of the infant incubator is not compromised, thereby effectively avoiding external contamination and reducing the risk of cross-infection.

[0050] Specifically, the external host 1 includes a lower housing 3 and an operation panel 4. Inside the lower housing 3, a ring-shaped first induction coil 5, a drive motor 6, and a host circuit board 8 are coaxially arranged. The drive motor 6 is coaxially and fixedly connected to the lower housing 3, and its output shaft extends towards the infant incubator lid and is fixedly connected to a first magnetic coupling disk 7. The operation panel 4 is electrically connected to the host circuit board 8 and is used to display detection data and perform operation settings. The lower housing 3 and the operation panel 4 are detachably snap-fitted together, a design that facilitates later maintenance and repair of internal components such as the host circuit board 8, the first induction coil 5, and the drive motor 6. The host circuit board 8 is fixed inside the lower housing 3 and electrically connected to both the first induction coil 5 and the drive motor 6, ensuring the reliability of power transmission and drive, and ensuring the coordinated operation of all functional modules of the external host 1.

[0051] The built-in sterile testing tray 2 has a sealed cavity structure, including a detachable and snap-fit ​​testing tray arc-shaped cover 9 and a testing tray base plate 10. A testing well 11 is provided through the center of the testing tray arc-shaped cover 9. This testing well 11 is completely sealed and isolated from the internal sealed cavity of the built-in sterile testing tray 2 to prevent contamination.

[0052] A second induction coil 12 is coaxially fixed on the bottom plate 10 of the detection tray, and an annular circuit board 13 is arranged above it. The second induction coil 12 is electrically connected to the annular circuit board 13, and both are arranged around the detection well 11. A temperature sensor 14 and a humidity sensor 15 are embedded in the inner wall of the detection well 11. Both sensors are electrically connected to the annular circuit board 13 and are used to collect temperature and humidity data in the incubator.

[0053] The bottom of the detection well 11 is rotatably connected to a second magnetic coupling disk 16 via a bearing. The second magnetic coupling disk 16 is coaxially arranged with the first magnetic coupling disk 7 on the external host 1, and the power coupling is achieved by magnetic attraction. The upper end face of the second magnetic coupling disk 16 is coaxially fixedly connected to a drive rod 17.

[0054] The external host 1 provides wireless power to the ring circuit board 13, temperature sensor 14, and humidity sensor 15 through electromagnetic induction coupling of the first induction coil 5 and the second induction coil 12. Simultaneously, the detection data from the temperature sensor 14 and humidity sensor 15 are also transmitted to the external host 1 via electromagnetic induction coupling and ultimately displayed on the operation panel 4. This wireless power supply and data transmission method avoids the contamination risks associated with wired connections and improves the overall sterility of the system.

[0055] To achieve efficient air circulation and improve detection accuracy, this device is designed with a special drive and lifting structure: a first lifting tower 18 is axially slidably connected inside the detection well 11, and the side wall of the first lifting tower 18 has an array of air outlets 1801. A centrifugal fan 19 is coaxially rotatably connected inside the tower, and the centrifugal fan 19 has a through air inlet hole 1901 in the center. The drive rod 17 passes through the air inlet hole 1901 and forms a circumferential limiting and axial sliding fit with the centrifugal fan 19.

[0056] Specifically, the outer wall of the drive rod 17 is integrally formed with several first sliding limiting strips 1701 extending axially. The inner wall of the air inlet 1901 of the centrifugal fan 19 is provided with axial grooves that are adapted to the first sliding limiting strips 1701 one by one. The first sliding limiting strips 1701 slide in cooperation with the axial grooves to achieve circumferential limiting of the drive rod 17 and the centrifugal fan 19. This design ensures that the drive rod 17 can synchronously drive the centrifugal fan 19 to rotate when it rotates, thereby realizing air circulation drive. At the same time, it allows the two to slide relative to each other axially without affecting the subsequent axial lifting and lowering action of the lifting tower, ensuring the stability and motion coordination of the transmission structure.

[0057] The first lifting tower 18 has a central hole 1804 extending axially at its center, and a second lifting tower 20 is slidably connected to the central hole 1804 along the axial direction. The side wall of the second lifting tower 20 has several air inlets 2001, and a threaded rod 21 is coaxially fixedly connected to the lower end face of the second lifting tower 20. The center of the drive rod 17 has a threaded hole 1702 adapted to the threaded rod 21, and the threaded rod 21 is threadedly engaged with the threaded hole 1702. When the drive motor 6 drives the first magnetic coupling disk 7 and the second magnetic coupling disk 16 to rotate, the drive rod 17 rotates synchronously. Because the first lifting tower 18 and the second lifting tower 20 are constrained by the limiting structure and cannot rotate with the drive rod 17, the threaded rod 21 remains fixed. At this time, the rotation of the drive rod 17 drives the threaded rod 21 to move axially through thread engagement, thereby driving the second lifting tower 20 and the first lifting tower 18 to move synchronously.

[0058] In a preferred embodiment, the outer wall of the first lifting tower 18 is integrally formed with a plurality of axially extending second sliding limiting strips 1802, and the inner wall of the detection well 11 is provided with axial limiting grooves that are adapted to each of the second sliding limiting strips 1802. The second sliding limiting strips 1802 slide in cooperation with the axial limiting grooves to restrict the circumferential rotation of the first lifting tower 18. This design ensures that the first lifting tower 18 can only move up and down axially, preventing it from rotating synchronously with the drive rod 17, so that the threaded engagement transmission between the threaded rod 21 and the drive rod 17 is accurately converted into the lifting action of the first lifting tower 18, realizing the stable opening and closing of the airflow channel.

[0059] Furthermore, the outer wall of the second lifting tower 20 is integrally formed with several axially extending third sliding limit strips 2002. The inner wall of the central hole 1804 is provided with axial limiting grooves that are adapted to each of the third sliding limit strips 2002. The third sliding limit strips 2002 slide in cooperation with the axial limiting grooves to restrict the circumferential rotation of the second lifting tower 20. Through the adaptation of the third sliding limit strips 2002 with the axial limiting grooves, it is ensured that the second lifting tower 20 can only slide axially along the central hole 1804 of the first lifting tower 18. This allows the threaded rod 21 to drive the second lifting tower 20 to move up and down precisely under the action of threaded transmission, realizing the synchronous opening and closing of the air inlet 2001. This, together with the air outlet 1801, forms a complete air circulation path, ensuring the stability and efficiency of the entire air circulation system.

[0060] To automatically close the airflow channel when the device stops working, this invention includes a first return spring 1803 and a second return spring 2003. The first return spring 1803 is sleeved on the outside of the first lifting tower 18. The lower end face of the first lifting tower 18 has an integrally formed annular limiting edge. The first return spring 1803 abuts against the annular limiting edge and the upper end face of the arc-shaped cover 9 of the detection disc, and is always in a compressed state, providing axial return force for the first lifting tower 18. When the drive rod 17 stops rotating, the force of the first return spring 1803 automatically drives the first lifting tower 18 back to its initial position, closing the air outlet 1801, maintaining the sealed environment of the detection well 11, facilitating subsequent disinfection and storage, and preventing impurities from entering the detection well 11 and affecting the sensor accuracy when not in operation.

[0061] Similarly, a second return spring 2003 is sleeved on the outer side of the second lifting tower 20. An annular limiting edge is integrally formed on the lower end face of the second lifting tower 20. The second return spring 2003 abuts against the annular limiting edge and the upper end face of the first lifting tower 18, and is always in a compressed state, providing axial return force for the second lifting tower 20. The compression design of the second return spring 2003 is linked with the first return spring 1803. After the device stops, it drives the second lifting tower 20 to fall back synchronously to close the air inlet 2001, further enhancing the sealing effect of the detection well 11, ensuring the sterile environment inside the built-in sterile detection plate 2, and preventing moisture and impurities from entering and damaging the internal circuitry or sensors.

[0062] To achieve thorough disinfection of the built-in sterile testing tray 2, this invention employs sealing structures in multiple locations: an annular sealing gasket is provided between the arc-shaped cover 9 of the testing tray and the base plate 10 of the testing tray; an annular rubber gasket is provided between the first lifting tower 18 and the opening end of the testing well 11; and an annular rubber gasket is provided between the second lifting tower 20 and the upper opening of the central hole 1804. These sealing designs create a high-strength waterproof seal with an IP67 or higher rating for the internal sealed chamber of the built-in sterile testing tray 2. This not only ensures complete isolation of the internal circuitry, coils, and other components of the testing tray from the outside but also allows the built-in sterile testing tray 2 to be directly immersed in alcohol or disinfectant for disinfection. This greatly meets the sterility requirements of infant incubators and effectively prevents moisture from seeping into the incubator and damaging electronic components.

[0063] To optimize air circulation and detection accuracy, the air outlets 1801 are evenly distributed circumferentially along the side wall of the first lifting tower 18, and their openings are radially outwards, ensuring uniform diffusion of the discharged air into the incubator and preventing localized airflow concentration. Similarly, the air inlets 2001 are evenly distributed circumferentially along the side wall of the second lifting tower 20, and their openings are radially inwards, enabling efficient intake of air from the incubator. The coordinated operation of the air outlets 1801 and inlets 2001 creates a stable and uniform air circulation field, ensuring that the temperature sensor 14 and humidity sensor 15 detect accurate data of the overall environment within the incubator, significantly improving the accuracy and representativeness of the detection results.

[0064] Regarding magnetic coupling, both the first magnetic coupling disk 7 and the second magnetic coupling disk 16 are neodymium iron boron permanent magnets, with opposite magnetic poles on their opposing surfaces. Furthermore, both the first magnetic coupling disk 7 and the second magnetic coupling disk 16 are composed of multiple fan-shaped regions joined together, with adjacent regions having opposite magnetic pole directions, thus forming a stable coupling. The use of high-strength neodymium iron boron permanent magnets in the coupling disks ensures the magnetic attraction strength between the external host 1 and the built-in sterile detection disk 2, achieving stable positioning. The design of opposite magnetic poles on opposing surfaces and opposite magnetic poles in adjacent fan-shaped regions enhances the magnetic coupling effect, improves power transmission efficiency, and allows the rotational power of the drive motor 6 to be accurately and stably transmitted to the drive rod 17 of the built-in sterile detection disk 2. Simultaneously, the non-contact transmission method avoids damaging the sealing of the detection disk.

[0065] In use, first place the external main unit 1 on top of the infant incubator lid, and then place the built-in sterile detection tray 2 below the infant incubator lid. The two are coupled and fixed together by the mutual attraction of the first magnetic coupling tray 7 and the second magnetic coupling tray 16. Since the internal circuitry of the built-in sterile detection tray 2 is completely sealed and contains no dangerous devices such as batteries, it can be completely immersed in alcohol or disinfectant for sterilization. Therefore, placing it inside the infant incubator is harmless and risk-free.

[0066] After installation, the external host 1 supplies power to the annular circuit board 13, temperature sensor 14, and humidity sensor 15 within the built-in sterile detection plate 2 via electromagnetic induction between the first induction coil 5 and the second induction coil 12. At this time, the drive motor 6 within the external host 1 starts, driving the first magnetic coupling plate 7 to rotate; the first magnetic coupling plate 7 drives the second magnetic coupling plate 16 to rotate via magnetic coupling, which in turn drives the drive rod 17 to rotate. Because the first lifting tower 18 and the second lifting tower 20 are constrained by the limiting structure, they can only slide up and down and cannot rotate; therefore, the threaded rod 21 connected to the second lifting tower 20 remains fixed. When the drive rod 17 rotates, its central threaded hole 1702 engages with the threaded rod 21, causing the threaded rod 21 to rise upwards. This, in turn, pushes the second lifting tower 20 and the first lifting tower 18 upwards, exposing the air outlet 1801 and the air inlet 2001. Simultaneously, the drive rod 17 drives the centrifugal fan 19 to rotate, which discharges the air inside the detection well 11 to the surroundings through the air outlet 1801. Under negative pressure, external air enters the first lifting tower 18 through the air inlet 2001 and then enters the detection well 11 through the air inlet 1901. At this time, the temperature sensor 14 and humidity sensor 15 on the inner wall of the detection well 11 are in full contact with the flowing air, achieving temperature and humidity detection. The detected data is transmitted to the external host 1 for real-time display via electromagnetic induction.

[0067] Compared to the drawbacks of traditional temperature and humidity sensors that are in contact with the still air inside the infant incubator, resulting in inaccurate test results, this solution can form a stable and efficient air circulation, making the test results more accurate. At the same time, the built-in sterile test tray 2 of this solution is safer and easier to disinfect. During use, the infant incubator can remain completely closed and can be operated from the outside, which greatly meets the safety, accuracy and convenience requirements of temperature and humidity testing of infant incubators.

[0068] In the second embodiment, when the drive motor 6 is working, the drive rod 17 is rotated through magnetic coupling. The rotation of the drive rod 17 drives the first lifting tower 18 and the second lifting tower 20 to rise through the threaded engagement, so that the array of air outlets 1801 on the side wall of the first lifting tower 18 and the several air inlets 2001 on the side wall of the second lifting tower 20 are fully exposed, opening the air circulation channel. On the other hand, the drive rod 17 drives the centrifugal fan 19 to rotate synchronously at high speed through circumferential limiting.

[0069] When the centrifugal fan 19 rotates, it accelerates the still air inside the detection well 11 through its blades and pushes it outward radially. Since the air outlet 1801 is evenly distributed along the side wall of the first lifting tower 18 and the opening direction is radially outward, the pushed air can be evenly diffused into the internal space of the infant incubator, avoiding excessively strong or concentrated local airflow and ensuring uniform disturbance to the temperature and humidity environment inside the incubator.

[0070] While the centrifugal fan 19 exhausts air, a local negative pressure zone is formed inside the detection well 11. At this time, air inside the incubator is drawn in through the air inlet 2001 under the influence of atmospheric pressure difference. Since the air inlet 2001 is evenly distributed circumferentially along the side wall of the second lifting tower 20 and its opening direction is radially inward, it can efficiently and evenly draw air from the incubator, avoiding local deviations that may be caused by drawing air from only one direction. The drawn-in air enters the interior of the second lifting tower 20 through the air inlet 2001, then enters the interior of the first lifting tower 18 through the central hole 1804, and finally enters the air intake area of ​​the centrifugal fan 19 through the central air intake hole 1901.

[0071] Thus, a stable and continuous air circulation field is formed inside the detection well 11, where air is drawn in through the air inlet 2001, accelerated by the centrifugal fan 19, and then discharged through the air outlet 1801. In this air circulation field, the temperature sensor 14 and the humidity sensor 15 are always in full contact with the high-speed flowing air to be measured. The flowing air can quickly transmit the overall temperature and humidity information inside the incubator, enabling the sensors to respond quickly and accurately to environmental changes and provide high-precision real-time measurement data.

[0072] The instantaneous temperature and humidity analog signals collected by temperature sensor 14 and humidity sensor 15 are converted into digital signals by the analog-to-digital converter on the ring circuit board 13. These digital signals are wirelessly transmitted to the first induction coil 5 of the external host 1 via electromagnetic induction through the second induction coil 12. Subsequently, the host circuit board 8 processes and calibrates the received digital signals, and finally displays them in real time in an intuitive digital form on the operation panel 4. Operators can perform calibration operations based on the displayed data and can store or export the data for analysis.

[0073] This embodiment overcomes the problem of inaccurate data caused by the sensor contacting still air in traditional verification by precisely controlling the air circulation path and ensuring full contact between the sensor and the flowing air, thus significantly improving the representativeness and reliability of the verification results.

[0074] In Example 3, the sealed cavity structure of the built-in sterile testing tray 2 and its high-strength waterproof seal with an IP67 rating or higher are the core guarantees of its sterile disinfection capability. After the calibration task is completed, the operator can easily remove the built-in sterile testing tray 2 from the inside of the infant incubator lid. Since it does not contain components such as batteries that may react with the disinfectant or pose a safety hazard, the built-in sterile testing tray 2 can be directly immersed in medical alcohol, sodium hypochlorite solution, or other disinfectants that meet medical standards for thorough disinfection. This disinfection method is simple, efficient, and ensures that both the internal and external surfaces of the built-in sterile testing tray 2 meet strict sterility requirements, avoiding the dead corners or incomplete disinfection problems that may exist in traditional wiping disinfection.

[0075] The contactless magnetic attraction and fixation between the built-in sterile detection tray 2 and the external host 1, along with wireless electromagnetic induction power supply and data transmission, fundamentally eliminate any physical connections or perforations that could compromise the sterile environment of the infant incubator. This means that throughout the entire calibration process, the infant incubator remains completely sealed, and the internal sterile air does not exchange with the external environment, thus maximizing the protection of newborns from external contamination and infection.

[0076] In addition, the real-time data display function of the operation panel 4 allows the verification personnel to conveniently and quickly observe changes in temperature and humidity; the entire verification process is designed to be extremely simple and efficient.

[0077] The separate design of the external host 1 and the built-in sterile detection tray 2 ensures that all power supply, drive and data processing units are located outside the incubator during the verification process. The built-in sterile detection tray 2 has a simple structure, containing only a temperature sensor 14, a humidity sensor 15, a second induction coil 12 and a ring circuit board 13, which minimizes the number and complexity of electronic components placed inside the infant incubator, thereby eliminating any potential electrical failures or heat dissipation that could affect the incubator environment and the safety of the infant.

[0078] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
