Abstract
Description
Technical Field
[0001] This utility model relates to the field of temperature measurement technology, specifically to a body temperature sensor. Background Technology
[0002] A body temperature sensor is a device that measures the temperature of an object or the human body. It typically consists of a sensing element, signal processing circuitry, and an output interface. Body temperature sensors are widely used in various fields such as medicine, health monitoring, motion tracking, and smart homes.
[0003] Body temperature sensors primarily detect body temperature through sensing elements. When these elements come into contact with the human body, they convert the body temperature into electrical signals. These electrical signals undergo analog-to-digital conversion and processing, and the microprocessor calculates the actual body temperature value, which is then output through a display screen or other devices. The entire process relies on the sensor's sensitivity to temperature changes and the precise conversion and processing by the electronic circuitry. To accurately measure body temperature, the sensor needs to maintain stable contact with the skin. As the person being measured moves, the sensor may also move, affecting the accuracy of the measurement. Traditional body temperature sensors often use an adhesive-on wearing method, which is very inconvenient to remove. In addition, due to different users having different body shapes and needs, the adhesive-on wearing method has certain limitations.
[0004] In view of this, a body temperature sensor is proposed. Utility Model Content
[0005] The purpose of this invention is to solve the problem that traditional body temperature sensors are inconvenient to adjust when worn, and to provide a body temperature sensor.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a body temperature sensor, including a sensor body, a plug, and a data transmission line for connecting the sensor body and the plug. A fixing component is fixedly connected to the sensor body. The fixing component includes a first fixing strap, a second fixing strap, and a connecting block fixedly connected to the first fixing strap. A slot for inserting the second fixing strap is provided on the connecting block. A locking rod for fixing the second fixing strap and the connecting block is detachably provided in the slot.
[0007] Preferably, a locking block is fixedly connected to the end of the locking rod. Multiple first channels, adapted to the dimensions of the locking block and locking rod, are equally spaced on the connecting block for the passage of the locking block. Multiple second channels, adapted to the dimensions of the locking block and locking rod, are equally spaced on the second fixing band for the passage of the locking block. Multiple third channels, adapted to the dimensions of the locking block and locking rod, are equally spaced within the slot for the passage of the locking block. A locking groove for locking the locking block and locking rod is formed within each third channel. The locking groove is offset from the third channel to prevent the locking block from disengaging from the locking groove.
[0008] Preferably, both the first fixing band and the second fixing band have a layered structure, and the first fixing band and the second fixing band are, from bottom to top, a contact layer, a buffer layer, a support layer and a protective layer.
[0009] Preferably, the contact layer is made of medical-grade silicone with a thickness of 100-500 μm. The contact layer is used to directly contact the user's skin and reduce skin irritation, thereby improving wearing comfort.
[0010] Preferably, the buffer layer is made of breathable polyester fiber with a thickness of 500-1000 μm, and the buffer layer is used to absorb sweat to keep the skin at the temperature measurement site dry.
[0011] Preferably, the support layer is made of polycarbonate sheet with a thickness of 1000-2000 μm, and the support layer is used to provide structural strength.
[0012] Preferably, the protective layer is made of thermoplastic polyurethane with a thickness of 500-1500 μm, and the protective layer is used to improve the wear resistance of the first fixing belt and the second fixing belt.
[0013] Compared with the prior art, this utility model has the following beneficial effects:
[0014] 1. The body temperature sensor provided by this utility model has an adjustable setting between the first fixing band and the second fixing band, which allows the body temperature sensor to be adjusted for users with different body types and needs, ensuring stable contact between the body temperature sensor and the skin and improving the accuracy of measurement.
[0015] 2.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] Please see Figure 1-6 .
[0027] This utility model of a body temperature sensor includes a sensor body 1, a plug 3, and a data transmission line 2 for connecting the sensor body 1 and the plug 3. A fixing component 4 is fixedly connected to the sensor body 1. The fixing component 4 includes a first fixing strap 5, a second fixing strap 6, and a connecting block 7 fixedly connected to the first fixing strap 5. The connecting block 7 has a slot 71 for inserting the second fixing strap 6. A locking rod 8 for fixing the second fixing strap 6 and the connecting block 7 is detachably provided in the slot 71. This arrangement allows the sensor to fit more stably against the skin of the person being measured, improving the accuracy of the temperature sensor measurement.
[0028] Specifically, a locking block 9 is fixedly connected to the end of the locking rod 8. Multiple first channels 10, which are adapted to the size of the locking block 9 and the locking rod 8, are equally spaced on the connecting block 7 for the locking block 9 to pass through. Multiple second channels 11, which are adapted to the size of the locking block 9 and the locking rod 8, are equally spaced on the second fixing band 6 for the locking block 9 to pass through. Multiple third channels 12, which are adapted to the size of the locking block 9 and the locking rod 8, are equally spaced in the slot 71 for the locking block 9 to pass through. A locking groove 13 for locking the locking block 9 and the locking rod 8 is provided in the third channel 12. The locking groove 13 is staggered from the third channel 12 to prevent the locking block 9 from disengaging from the locking groove 13. That is, when the locking rod 8 is locked, it drives the locking block 9 to pass through the first channel 10, the second channel 11 and the third channel 12 in sequence, and then locks it in the locking groove 13 in the third channel 12.
[0029] Secondly, both the first fixing band 5 and the second fixing band 6 are layered structures, and from bottom to top, the first fixing band 5 and the second fixing band 6 are a contact layer 14, a buffer layer 15, a support layer 16 and a protective layer 17.
[0030] The contact layer 14 is made of medical-grade silicone with a thickness of 100-500μm. The contact layer 14 is used to make direct contact with the user's skin and reduce skin irritation, thereby improving the comfort of wearing it. Since silicone has good biocompatibility and softness, it can ensure that the skin will not have an allergic reaction. In addition, its good thermal conductivity ensures the accurate transfer of body temperature.
[0031] In addition, the buffer layer 15 is made of breathable polyester fiber with a thickness of 500-1000μm. The buffer layer 15 is used to absorb sweat to keep the skin at the temperature measurement site dry. This design can increase the comfort of wearing and prevent skin indentations or discomfort caused by prolonged wear. At the same time, the buffer layer 15 can maintain the stability of the sensor and reduce displacement caused by movement, thereby improving the accuracy of body temperature measurement.
[0032] Furthermore, the support layer 16 is made of polycarbonate sheet with a thickness of 1000-2000μm. The support layer 16 is used to provide structural strength to further maintain the stability of the sensor.
[0033] Furthermore, the protective layer 17 is made of thermoplastic polyurethane with a thickness of 500-1500μm. The protective layer 17 is used to improve the wear resistance of the first fixing belt 5 and the second fixing belt 6 and extend the service life of the first fixing belt 5 and the second fixing belt 6.
[0034] It should be noted that the lengths of the first fixing band 5 and the second fixing band 6 can be adjusted according to the body temperature measurement requirements during specific settings. For example, the length of the fixing band for measuring body temperature at the arm should be much shorter than the length of the fixing band for measuring body temperature at the head or chest. In addition, the locking groove 13 can be set such that the thickness of the bottom of the groove is less than the thickness of the opening, so as to increase the limiting effect of the locking groove 13 on the rotating locking block 9.
[0035] 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 exemplary 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.
