Description

Technical Field

[0001] This utility model relates to the field of infant care technology, and in particular to an infant monitor that can monitor an infant's body temperature. Background Technology

[0002] In existing technical literature, Chinese utility model publication CN217283049U discloses "a body temperature detection type intelligent baby monitor". It captures real-time video of the baby through a camera. The intelligent analysis module can intelligently determine whether the baby has kicked off the blanket by analyzing the baby's video. At the same time, it locks the temperature measurement point and uses a thermal infrared lens to accurately measure the temperature. Therefore, it is more practical and has more comprehensive functions than monitors that only provide a cry detection. In addition, this monitor can be clamped to the baby's crib with a clamping device, so the baby does not need to wear the sensor. It does not disturb the baby's sleep and will not cause data distortion due to sensor detachment.

[0003] Thermal infrared lenses can remotely monitor an infant's body temperature. However, since they are used indoors, they are inevitably affected by the air conditioning. When the air conditioning air gathers in front of the thermal infrared lens, it will significantly affect the accuracy of the temperature measurement.

[0004] For example, air conditioning air blowing from the back or top of the monitor can cause the Coanda effect due to the curvature of the camera casing. The air conditioning air flows along the curved surface of the casing and adheres to the thermal infrared lens, which has a significant impact on the infrared thermal imaging detection effect.

[0005] In addition, due to the addition of many internal components and the relatively compact internal space, it is not conducive to the installation of each module and to avoiding mutual thermal interference. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this invention aims to provide an infant monitor that can monitor an infant's body temperature and solve at least one of the aforementioned technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an infant monitor that can monitor an infant's body temperature, comprising an infant monitor housing, the infant monitor housing having an internal installation space, within which a visible light camera and an infrared thermal imaging module are installed, the infrared thermal imaging module including a thermal infrared detector, the front end of the infant monitor housing having a visible light shooting window corresponding to the visible light camera and a thermal infrared detection window corresponding to the thermal infrared detector, the front end of the infant monitor housing having a protruding air guide portion near the thermal infrared detection window, the air guide portion having a distal end away from the infant monitor housing, the distal end of the air guide portion being positioned away from the thermal infrared detection window;

[0008] The side of the air guide section away from the thermal infrared detection window has an air guide surface that is continuous with the surface of the baby monitor housing. The air guide surface is configured to guide the air flowing from the rear end to the front end of the baby monitor housing away from the thermal infrared detection window.

[0009] A further technical solution of this utility model: the internal installation space of the baby monitor housing extends to the air guide to form an outwardly protruding additional installation space.

[0010] Further technical solution of this utility model: The infrared thermal imaging module also includes a PCB board, the thermal infrared detector is soldered on the PCB board, and the additional installation space constitutes at least a part of the board body that accommodates the PCB board.

[0011] A further technical solution of this utility model: the air guide is located above the thermal infrared detection window on the front end of the baby monitor housing, and the far end of the air guide is set away from the thermal infrared detection window in the forward and upward direction.

[0012] A further technical solution of this utility model: the visible light shooting window and the thermal infrared detection window are arranged at a left-right interval at the front end of the baby monitor housing.

[0013] A further technical solution of this utility model: the air guide extends to the left and right to be located above both the visible light imaging window and the thermal infrared detection window.

[0014] A further technical solution of this utility model includes a bottom mounting base, on which a first motor is mounted, and a retainer is provided above the bottom mounting base. The first motor drives the retainer to rotate about the vertical axis as the rotation axis.

[0015] A further technical solution of this utility model: the retainer has a frame body connected to the rotary output shaft of the first motor, and retaining arms extending upward on the left and right sides of the frame body, the frame body and the retaining arms on both sides forming a mounting position;

[0016] The baby monitor housing is located at the mounting position, and a second motor is installed inside the baby monitor housing;

[0017] The left side of the baby monitor housing is rotatably connected to the left retaining arm via a pivot. The rotation output shaft of the second motor is set to the left and right, and extends to the right to connect with the right retaining arm.

[0018] A further technical solution of this utility model: the frame of the retainer and the retaining arms on both sides are respectively close to the bottom end, the left end and the right end of the baby monitor housing, and the frame of the retainer and the retaining arms on both sides form windproof components.

[0019] Compared with the existing technology, the beneficial effect of this technical solution is that when the air conditioning air flows from the rear end of the baby monitor housing to the front end of the baby monitor housing, it can be guided by the air guide to be away from the thermal infrared detection window, so as to reduce the influence of the air conditioning air on the thermal infrared temperature measurement, thereby making the baby's temperature measurement more accurate.

[0020] The PCB board of the infrared thermal imaging module can be kept as far away as possible from other heat-generating components inside the baby monitor housing by adding additional installation space, so as to avoid mutual thermal interference as much as possible.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figure 1-3 An infant monitor capable of monitoring an infant's body temperature includes an infant monitor housing 1, which has an internal mounting space 101. A visible light camera 2 and an infrared thermal imaging module are disposed within the internal mounting space 101. The infrared thermal imaging module includes a thermal infrared detector 3.

[0038] The front end of the baby monitor housing 1 has a visible light shooting window 102 corresponding to the visible light camera 2 and a thermal infrared detection window 103 corresponding to the thermal infrared detector 3.

[0039] An air guide 4 is formed on the front end of the baby monitor housing 1 near the thermal infrared detection window. The air guide 4 has a far end away from the baby monitor housing, and the far end of the air guide 4 is positioned away from the thermal infrared detection window 103.

[0040] The air guide section 4 has an air guide surface 401 on the side away from the thermal infrared detection window 103, which is continuous with the surface of the baby monitor housing. The air guide surface 401 is configured to guide the air flowing from the rear end of the baby monitor housing 1 to the front end of the baby monitor housing 1 away from the thermal infrared detection window 103.

[0041] When the air conditioning air flows from the rear end of the baby monitor housing 1 to the front end of the baby monitor housing 1, it can be guided by the air guide 4 to move away from the thermal infrared detection window 103, so as to reduce the influence of the air conditioning air on the thermal infrared temperature measurement, thereby making the baby's temperature measurement more accurate.

[0042] In some embodiments, the internal mounting space 101 of the baby monitor housing extends to the air guide portion to form an outwardly protruding additional mounting space 104.

[0043] Preferably, the infrared thermal imaging module further includes a PCB board 5, on which the thermal infrared detector 3 is soldered, and the additional mounting space 104 constitutes at least a portion of the board body accommodating the PCB board 5. The PCB board 5 of the infrared thermal imaging module can be kept as far away as possible from other heat-generating components within the baby monitor housing through the additional mounting space 104, so as to minimize mutual thermal interference.

[0044] The air guide section serves two purposes: firstly, it directs airflow to make temperature measurement of the baby more accurate; secondly, it provides additional installation space to minimize thermal interference between the heating components inside the baby monitor housing.

[0045] In some embodiments, the air guide 4 is located above the thermal infrared detection window 103 on the front end of the baby monitor housing 1, with the distal end of the air guide 4 facing forward and upward (or understood as obliquely forward and upward, or the resultant direction of forward and upward force) away from the thermal infrared detection window. The air guide 4 can be used to guide the rearward wind and block the upward wind.

[0046] In some embodiments, the visible light imaging window 102 and the thermal infrared detection window 103 are arranged at a left-right interval at the front end of the baby monitor housing 1.

[0047] In some embodiments, the air guide extends to the left and right, simultaneously positioned above the visible light imaging window and the thermal infrared detection window.

[0048] In some embodiments, the baby monitor further includes a bottom mounting base 6, on which a first motor 7 is mounted and a retainer 8 is provided. The first motor 7 is used to drive the retainer 8 to rotate.

[0049] Specifically, the first motor drives the retainer 8 to rotate around the vertical axis. For example, the housing of the first motor 7 is mounted on the bottom mounting base 6, and the rotation output shaft of the first motor 7 is vertically positioned.

[0050] The retainer 8 is located above the bottom mounting base 6. The upper end of the rotation output shaft of the first motor 7 is connected to the retainer 8. When the first motor 7 is working, it drives the retainer 8 to rotate relative to the bottom mounting base 6.

[0051] like Figure 1 As shown, the retainer 8 has a frame 801 connected to the rotary output shaft of the first motor 7. The left and right sides of the frame 801 have upwardly extending retaining arms 802a and 802b. The frame 801 and the retaining arms 802a and 802b on both sides surround to form a mounting position 803.

[0052] The baby monitor housing 1 is located at the mounting position 803. A second motor 9 is installed inside the baby monitor housing 1. The second motor 9 is used to drive the baby monitor housing 1 to rotate relative to the retainer 8 with the horizontal axis as the rotation axis.

[0053] Specifically, the baby monitor housing 1 is cylindrical or near-cylindrical in shape, extending left and right. The left side of the baby monitor housing 1 is rotatably connected to the left retaining arm 802a via a rotating shaft 105. The rotation output shaft of the second motor 9 is set left and right, and the rotation output shaft of the second motor 9 extends to the right to connect with the right retaining arm 802b.

[0054] When the second motor 9 is working, it can drive the baby monitor housing 1 to rotate relative to the retainer 8.

[0055] like Figure 1 As shown, the frame 801 of the retainer and the retaining arms 802a and 802b on both sides are close to the bottom end, the left end and the right end of the baby monitor housing 1, respectively. The frame 801 of the retainer and the retaining arms 802a and 802b on both sides all form windproof components.

[0056] The retainer 8 provides rotational support for the baby monitor housing 1. Furthermore, the airflow from the rear, lower, and front ends of the baby monitor housing is affected by the retainer's frame; the airflow from the rear, left, and front ends of the baby monitor housing is affected by the left retaining arm; and the airflow from the rear, right, and front ends of the baby monitor housing is affected by the right retaining arm. Combined with the air guide located above the thermal infrared detection window, this design effectively reduces the accumulation of airflow from the rear to the front of the baby monitor housing at the thermal infrared detection window, thus minimizing its impact on the thermal infrared module's temperature detection.

[0057] In this embodiment, the acquisition angles of the visible light camera and the thermal infrared detector can be adjusted accordingly by the first motor and the second motor.

[0058] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
