In order to facilitate an understanding of the present disclosure, the present disclosure is described in more detail below in conjunction with the accompanying drawings and specific examples. It will be understood that when an element is referred to as being "fixed" to another element, it can be directly on the other element or one or more intervening elements may be present therebetween. When an element is referred to as being "electrically connected" to another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The terms "upper," "lower," "inner," "outer," "bottom," and the like as used in this specification refer to an orientation or positional relationship based on that shown in the drawings, merely to facilitate description of the disclosure and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the disclosure. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in the description of the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The term "and/or" as used in this specification includes any and all combinations of one or more of the associated listed items. In addition, the technical features referred to in the different embodiments of the present disclosure described below may be combined with each other as long as they do not make a conflict with each other.
The embodiment of the disclosure provides an ear-hook measuring device. Referring to fig. 1 and 2, the ear-hook measuring device 10 includes an ear-hook body 20, an interface circuit 30, a body temperature sampling circuit 40, a control circuit 50 and a power module 60.
The earhook body 20 has a first end and an opposite second end for hanging over the ear of a user during measurement, wherein the earhook body 20 is curved in shape, generally in the shape of a "C". In some embodiments, the two ends of the ear-hook body 20 taper towards the middle, and the use of such a shaped ear-hook body 20 in this embodiment is advantageous for being able to be reliably hung on the ear.
The interface circuit 30 is disposed at a first end of the ear-hook body 20. Referring to fig. 3, the first end of the ear hook body 20 is provided with an interface slot 21, and the interface circuit 30 is disposed in the interface slot 21. The charging interface of the charging cradle can be inserted into the interface slot 21, which is connected to the interface circuit 30 in a suitable manner, wherein the interface circuit 30 can support not only a power supply but also a data transmission, i.e. the charging cradle transmits power to the on-the-ear measuring device 10 on the basis of the charging interface and the interface circuit 30 and can also transmit data to the on-the-ear measuring device 10.
The body temperature sampling circuit 40 includes at least one body temperature sensor 41 and a body temperature conditioning circuit 42, wherein the body temperature sensor 41 is disposed on the back surface of the ear-hook body 20 and electrically connected to the body temperature conditioning circuit 42, and the back surface is the surface facing the ear when the ear-hook body 20 is hung on the ear.
The body temperature sensors 41 are used for acquiring the temperature of the back of the ear, wherein the number of the body temperature sensors 41 can be one or more than two, and when the number of the body temperature sensors 41 is more than two, the plurality of body temperature sensors 41 can be distributed on the back of the ear hook body 20 according to a preset arrangement mode, for example, the preset arrangement mode is a matrix arrangement mode or a triangular array mode, etc. The use of multiple body temperature sensors 41 to measure the back of the ear can provide multiple back of the ear temperatures to the control circuit 50 simultaneously to determine a more accurate back of the ear temperature, i.e., to avoid the problem of incapacitation of a single body temperature sensor 41 when it is not functioning properly.
The body temperature conditioning circuit 42 is used for filtering and amplifying the back of the ear temperature acquired by the body temperature sensor 41, and outputting the conditioned back of the ear temperature, so as to prevent the signal corresponding to the back of the ear temperature from being too weak to be beneficial to recognition or loss.
When the user uses the ear-hook measuring device 10, the ear-hook body 20 can be hung on the ear, and since the body temperature sensor 41 is disposed on the back of the ear-hook body 20 facing the ear, the body temperature sensor 41 can measure the temperature closely to the back of the ear, on one hand, the ear-hook measuring device 10 can measure closely to the back of the ear in a short distance relative to the forehead temperature measurement mode, thus reducing the influence of the surrounding environment and improving the accuracy of the measurement result. On the other hand, with respect to the ear temperature measurement mode, the ear-hook measurement device 10 does not need to insert a probe into an earhole to perform measurement, and directly measures the temperature of the back of the ear, so as to reduce measurement pollution, and be beneficial to improving the acceptance of users and the experience of users.
The control circuit 50 is electrically connected to the interface circuit 30 and the body temperature conditioning circuit 42, respectively, where the control circuit 50 interacts with the charging stand through the interface circuit 30, and the control circuit 50 processes the conditioned back of the ear temperature, for example, when detecting that the back of the ear temperature is greater than the normal body temperature threshold, the control circuit 50 displays the back of the ear temperature and generates a prompt message, and when detecting that the back of the ear temperature is less than the normal body temperature threshold, the control circuit 50 displays the back of the ear temperature.
The power module 60 is electrically connected to the at least one body temperature sensor 41, the body temperature conditioning circuit 42 and the control circuit 50, respectively, for providing power and storing power. For example, the charging interface of the charging stand is in interface with the interface circuit 30, and the power module 60 is controlled by the control circuit 50, so that the power provided by the charging stand can be transmitted to the power module 60 for storage through the charging interface and the interface circuit 30. For another example, the power module 60 provides the normal operating voltage, such as 3.3V or 5V, to the body temperature sensor 41 and the body temperature conditioning circuit 42, respectively, under the control of the control circuit 50.
It is understood that the power module 60 may be a lithium battery pack or a battery pack made of other materials.

Wherein, the first preset distance can be any distance value between 0 and 5 cm. Since the retroauricular nephelium acupuncture point is one of the convergence of the artery and vein of the head, the body temperature sensor 41 can sample more reliable and accurate temperature data at the first measurement position 20 a.
In some embodiments, the first measurement location 20a is located above the behind-the-ear nebula acupoint.
In some embodiments, referring to fig. 5, the ear-hook measuring device 10 further includes at least one heart rate sensor 70 and a heart rate conditioning circuit 80, wherein the at least one heart rate sensor 70 is disposed at a second measuring position 20b of the ear-hook body 20 and is electrically connected to the heart rate conditioning circuit 80, and the heart rate conditioning circuit 80 is further electrically connected to the control circuit 50, and the second measuring position 20b is a position on the ear-hook body 20 spaced from a post-ear nebula hole of an ear by a second predetermined distance. Wherein the second preset distance may be any distance value between 0 and 5 cm. As previously described, since the behind-the-ear nebula is one of the convergence of the arteries and veins of the head, the heart rate sensor 70 is able to sample more reliable and accurate heart rate data at the second measurement location 20 b.
In some embodiments, the second measurement location 20b is directly opposite to the location of the behind-the-ear nebula, or the second measurement location 20b is located below the behind-the-ear nebula.
