Technical Field
[0001] This application relates to the technical field of heart rate monitoring sensor components, specifically heart rate monitoring sensor components. Background Technology
[0002] Heart rate monitoring sensors are sensor devices used to measure human heart rate, and are commonly used in wearable devices such as smartwatches, health bracelets, and fitness trackers.
[0003] Heart rate detection sensors measure human heart rate by contacting the human body surface. Since the carrier of the sensor is usually made of metal, the carrier part of the heart rate detection sensor is susceptible to corrosion by sweat, thereby reducing its service life. To address this issue, a heart rate monitoring sensor is proposed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a heart rate monitoring sensor element that has advantages such as easy installation and reduced corrosion from contact with sweat.
[0005] To achieve the above objectives, this application provides the following technical solution: a heart rate monitoring sensor, comprising a square glass carrier and electrocardiogram electrode contacts disposed on the glass carrier, a body temperature detection contact disposed at the bottom of the glass carrier, and an electrode disposed at the top of the glass carrier.
[0006] Furthermore, two electrocardiogram electrode contacts are distributed on the bottom surface of the glass carrier, and the two electrocardiogram electrode contacts are exposed on the outside of the glass carrier in an arc shape.
[0007] Furthermore, the body temperature detection contact and the electrocardiogram electrode contact are on the same plane.
[0008] Furthermore, a glass ring is embedded in the middle of the glass carrier, and a circular tube for easy connection is fixedly installed inside the glass ring. A circular mirror is provided at the bottom end of the circular tube.
[0009] Furthermore, a first countersunk hole is formed in the middle of the glass carrier, and a second countersunk hole penetrating the glass carrier is formed on the inner wall of the first countersunk hole.
[0010] Furthermore, two connecting posts are fixedly connected to the top end of the circular tube, and the connecting posts extend into the glass ring.
[0011] Furthermore, the four corners of the glass carrier are rounded, and the edges of the glass carrier are rounded.
[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0013] This heart rate monitoring sensor replaces the metal carrier with a square glass carrier, eliminating the need for the metal carrier to come into contact with human skin and thus preventing corrosion from sweat. Furthermore, by placing electrodes on both sides of the glass carrier, the contact area between the carrier and the user's arm is maximized, effectively improving the utilization rate of the carrier surface. Additionally, by installing a glass ring in the center of the glass carrier and attaching a round tube to the center of the glass ring, the installation and connection of the glass carrier are facilitated, enhancing the device's practicality.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0020] Please see Figure 1-4 The heart rate monitoring sensor in this embodiment includes a square glass carrier 1 and electrocardiogram electrode contacts 2 disposed on the glass carrier 1. There are two electrocardiogram electrode contacts 2 distributed on the bottom surface of the glass carrier 1. The two electrocardiogram electrode contacts 2 are arc-shaped and exposed on the outside of the glass carrier 1 for contact with the user's skin for monitoring.
[0021] Preferably, the four corners of the glass carrier 1 are rounded, and the edges of the glass carrier 1 are rounded.
[0022] In this application, the electrocardiogram electrode contacts 2 are mounted on a glass carrier 1, thereby reducing the corrosion of the sensing components by sweat.
[0023] In this embodiment, the bottom of the glass carrier 1 is also provided with a body temperature detection contact 3. Since the body temperature detection contact 3 and the electrocardiogram electrode contact 2 are on the same plane, the glass carrier 1 can conveniently complete the measurement of the user's body temperature simultaneously.
[0024] Specifically, the electrocardiogram electrode contact 2 and the body temperature detection contact 3 are coated with a conductive film on the glass carrier 1 by magnetron sputtering, and then laser-engraved into two electrodes.
[0025] It should be noted that an electrode 4 is provided on the top of the glass carrier 1 to facilitate connection between the electrocardiogram electrode contact 2 and the body temperature detection contact 3 inside the glass carrier 1. The electrode 4 is divided into two halves and installed on the entire surface of the glass carrier 1 to increase the contact area between the electrode and the user's arm.
[0026] This application eliminates the need for the contact points to come into contact with human skin, thus preventing the carrier from being corroded by sweat due to contact with human skin, by using a square glass carrier instead of a metal carrier.
[0027] To facilitate the connection of the glass carrier 1, a glass ring 5 is embedded in the middle of the glass carrier 1 in this embodiment. A round tube 9 is fixedly installed inside the glass ring 5. The glass ring 5 has a hole in the middle, and the hole surface is inserted into the round tube 9. A round mirror 10 is provided on the bottom end of the round tube 9. The round mirror 10 is installed on one end of the round tube 9 by embedding.
[0028] Preferably, the inner wall of the glass carrier 1 is further provided with a first annular countersunk hole 6, and the inner wall of the first countersunk hole 6 is provided with a second countersunk hole 7 penetrating the glass carrier 1. The second countersunk hole 7 and the first countersunk hole 6 are connected to form a hole with a T-shaped longitudinal section. The inner walls of the first countersunk hole 6 and the second countersunk hole 7 are printed with ink, firstly to increase the adhesion when the circular tube 9 is attached, and secondly to block light. The glass circular mirror 10 is an LED light-emitting hole, and the circular ring 5 is a light-receiving sensor. The printed ink separates the two.
[0029] Two connecting posts 8 are fixedly connected to the top of the round tube 9. The connecting posts 8 extend into the glass ring 5. The connection between the round tube 9 and the glass ring 5 is enhanced through the connection of the connecting posts 8.
[0030] The working principle of the above embodiments is as follows:
[0031] A square glass substrate 1 is formed by cold processing. Electrocardiogram (ECG) electrode contacts 2 and body temperature detection contacts 3 are embedded in the glass substrate 1 to form a sensing element. By directly contacting the glass substrate 1 with the user's skin, the user's heart rate can be monitored through the contact of the ECG electrode contacts 2 and body temperature detection contacts 3. At the same time, the circular tube 9 in the middle of the glass substrate 1 is connected to the installation equipment, so that the electrical signal generated by the contact between the glass substrate 1 and the user can be transmitted in a timely manner.
