As shown in fig. 1 to 4, the circuit board 2 is disposed in the cavity 11, the circuit board 2 has a first surface 23 and a second surface 24 opposite to each other, the first surface 23 of the circuit board 2 faces the transparent lens 3, the first surface 23 of the circuit board 2 is attached to the transparent lens 3, and the second surface 24 of the circuit board 2 is provided with the temperature sensor 5, or is further provided with a power filter capacitor related to the temperature sensor 5. Optionally, the second side 24 is a pad.

In some embodiments, the wiring board 2 comprises a first area 21 for arranging the temperature sensor 5, i.e. the first area 21 is at least a part of the wiring board 2, the first area 21 having at least a part of a first side 23 and a second side 24.

The optical biosensor 4 may be disposed in a second area of the wiring board 2 or in a wiring board different from the wiring board 2.

In some embodiments, a heat conducting medium 26 is disposed between the first face 23 of the circuit board 2 and the transparent lens 3, and the heat conducting medium is made of an electrically insulating material. For example, a heat conducting medium 26 is disposed between the heat conducting metal layer 25 and the transparent lens 3, so as to facilitate heat conduction of the heat conducting metal layer 25 and the transparent lens 3 through the heat conducting medium.

As shown in fig. 2, the first surface 23 and the second surface 24 are opposite to each other in the thickness direction of the transparent lens 3, the heat conductive metal layer 25 is connected to the transparent lens 3 through the heat conductive medium 26, and the metal via 22 is connected to the heat conductive pin of the temperature sensor 5. The heat conducting pins can be special pins, and can also share the power grounding pin 51 of the temperature sensor 5; the heat conduction pins can receive the body surface heat conducted by the light-transmitting lens 3. For example, the thermally conductive pins include a ground pin 51 and a data pin 52.

Optionally, the heat-conducting medium 26 includes at least one of a heat-conducting silicone sheet, a heat-conducting silicone grease, a heat-conducting silicone adhesive tape, a heat-conducting adhesive tape, a phase-change material, and a heat-conducting potting adhesive.

Optionally, the heat conductive metal layer 25 is sheet-shaped and forms a part of the first face 23 so that heat of the light-transmissive glass is easily conducted to the metal via 22.

Optionally, the temperature sensor 5 is a contact temperature sensor 5.

In practical application, when human body temperature detection is required, the body temperature detection device 100 is in contact with a human body, so that the transparent lens 3 is in contact with the human body skin 200, heat of the human body skin 200 sequentially passes through the transparent lens 3, the heat-conducting medium 26, the heat-conducting metal layer 25, the metal via hole 22 and the heat-conducting pin on the second surface 24, and the heat-conducting pin transmits body surface heat to the temperature sensor 5 for detecting the temperature of the human body skin 200. Because temperature sensor 5 passes through heat conduction metal layer 25 and the laminating setting of printing opacity lens 3, do not have direct electrical connection between temperature sensor 5 and the printing opacity lens 3 promptly, consequently in the temperature detect process, avoided taking place static and surge and lead to the phenomenon that temperature sensor 5 damaged.

For example, the thermally conductive metal layer 25 is a copper sheet. The shell is a bottom shell, the lower surface of the transparent lens 3 is suitable for contacting with the skin 200 of a human body, and the inner surface of the transparent lens 3 is attached to the heat-conducting metal layer 25 for conducting heat. The up-down direction is shown by the arrows in fig. 2. At this time, the light-transmitting lens 3 is located below the circuit board 2, the upper surface of the circuit board 2 is the second surface 24, the lower surface of the circuit board 2 is the first surface 23, the temperature sensor 5 is provided on the upper surface of the circuit board 2, and the lower surface of the copper heat-conducting layer 25 constitutes a part of the lower surface of the circuit board 2.

In some embodiments, the temperature sensor 5 is connected to other components within the device by conductive traces. For example, the temperature sensor 5 is electrically connected to the controller through a conductive line, wherein a zero-ohm resistor is connected in series to the conductive line. Specifically, the conducting circuit is arranged on the circuit board 2, and the zero-ohm resistor connected in series on the conducting circuit can be used for isolating heat conduction of the temperature sensor 5 and the controller, so that dissipation of heat conducted to the temperature sensor 5 by the conducting circuit can be reduced, and accuracy and heat balance speed of human body temperature detection are further improved.

In some embodiments, the temperature sensor 5 is coated with an insulating material 6 on the outside. Specifically, the surface of the chip package of the temperature sensor 5 is attached with heat insulation foam, the heat insulation foam enables the circuit board 2 connected with the temperature sensor 5 to be tightly attached to the transparent lens 3 by utilizing the compression force of the heat insulation foam so as to ensure the heat conduction effect, and is used for isolating other heat sources of the temperature body temperature detection device 100 and preventing the other heat sources from influencing the body temperature detection of the temperature sensor 5. For example, the insulating material 6 is positioned between the temperature sensor 5 and the heart rate circuit board 43 so that the heart rate circuit board 43 can press the insulating material 6 against the temperature sensor 5. In some embodiments, the temperature sensor 5 may be normally open, or the temperature sensor 5 may be dormant or off and turned on or activated by the controller when body temperature detection is required, for example, when human skin is detected to be in contact with the light-transmitting lens. As shown in fig. 3 and 4, the controller is electrically connected to the temperature sensor 5, and the controller is used to control the state of the temperature sensor 5. Specifically, the controller is configured to control the temperature sensor 5 to be in a sleep or off state, and to control the temperature sensor 5 to be switched from the sleep or off state to the operating state when it is determined that the activation condition is satisfied. For example, if the controller determines that the human body contact condition is satisfied, the controller controls the temperature sensor 5 to be switched to the operating state to detect the human body temperature. In addition, it should be noted that when the temperature sensor 5 communicates with the controller, the heat conducting pin can be used as a reference ground, so that the temperature sensor 5 and the controller share the same ground. When the transparent lens 3 in this embodiment contacts with the skin 200 of the human body, the transparent lens 3 transmits the body surface heat of the human body to the ground pin 51 and the data pin 52 through the heat-conducting metal layer 25 and the metal via hole 22, so as to transmit the body surface heat to the core of the temperature sensor 5 through the ground pin 51 and the data pin 52, thereby detecting the temperature of the human body. In addition, the data pin 52 in this embodiment may also serve as a communication port between the temperature sensor 5 and the controller, so as to transmit the temperature data of the temperature sensor 5 to the controller. It should be noted that, in general, the area of the ground pin 51 is larger than that of the data pin 52, and only the ground pin 51 with a larger area is used to realize rapid heat conduction; in order to realize rapid conduction of body surface heat, the body surface heat can be transmitted to the temperature sensor 5 by using the ground pin 51 and the data pin 52 simultaneously.

The metal vias 22 are metal traces that connect the layers of the circuit board 2 and, in addition to conducting electrical signals, also conduct heat in this embodiment. Alternatively, the optical biosensor 4 may be connected to a controller, and when the optical biosensor 4 for detecting a heart rate of a human body detects a heart rate of a human body, which indicates that the body temperature detecting apparatus 100 is in contact with the human body, the controller controls the temperature sensor 5 to collect the temperature of the human body.

As shown in fig. 4, in some embodiments, the body temperature detecting device 100 further comprises a contact sensor for detecting that the human skin contacts the light transmissive lens 3. Specifically, the contact sensor is connected to the controller and is used for detecting whether the light-transmitting lens 3 of the body temperature detection apparatus 100 is in a contact state with the human body; the controller is used for judging whether the light-transmitting lens 3 of the body temperature detection device 100 is in contact with the human body according to the output of the contact sensor.

The contact sensor can detect the contact state of the body temperature detection device 100 and the skin of the human body in real time, and send detected data to the controller, so that the controller 3 judges whether the body temperature detection device 100 is in contact with the human body according to the detected data, if so, an enable signal can be output to the temperature sensor 5, the temperature sensor 5 is controlled to enable operation, so that the current temperature of the human body is detected, and if not, the enable signal does not need to be output to the temperature sensor 5, namely, the current temperature of the human body does not need to be detected. The contact sensor may periodically perform contact state detection, or the controller controls the contact sensor to perform contact state detection when receiving a user instruction or determining that body temperature detection is needed, which is not limited herein.

In some embodiments, if the controller receives a body temperature detection instruction of the user and the detection data of the contact sensor indicates that the human skin does not contact the light-transmitting lens, the controller may control the device to send a prompt message to prompt the user to press the light-transmitting lens or to adjust the wearing tightness or wearing position of the device.

Alternatively, the contact sensor may be at least one of the following sensors: acceleration sensor, gyroscope, electronic compass, capacitive sensor or infrared sensor. Therefore, when the body temperature detection device 100 is detected to be worn or contacted with a human body through the contact sensor, the temperature of the human body is detected through the temperature sensor 5, and the phenomenon of overlarge power consumption caused by temperature detection when the body temperature detection device is not contacted with the human body is avoided, namely, unnecessary power consumption is reduced.

In some embodiments, the body temperature detection device 100 is a wrist-worn device, such as a smart watch or a smart bracelet, for ease of donning.

As shown in fig. 5, the present invention further provides a wearable device 300, according to the present invention, a body temperature detecting device 100 is provided.
