Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, specifically to a split-type temperature sensor. Background Technology

[0002] Currently, split-type temperature sensors generally fall into two categories: one type transmits data via a wireless communication module, and the other type connects the main body and the temperature sensing unit together via a signal source cable. While the latter type, connected via a signal source cable, is more stable, its temperature sensing unit and signal source cable are often connected by threads, and signal transmission is mostly a contact-to-contact method. Over time, these threads can loosen, leading to unstable contact between the contacts responsible for signal transmission and causing malfunctions.

[0003] Currently, there is a lack of a good split-type temperature sensor that can meet the diverse temperature sensing needs. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a split-type temperature sensor to solve the problem of unstable contact connection at the contact point responsible for signal transmission in the prior art, which is prone to disconnection and failure.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a split-type temperature sensor, comprising: a temperature sensing end, wherein the temperature sensing end is provided with a source output end that can change position, the source output end being used to output a source signal; a source docking end, wherein the source docking end is connected to the source output end, the source docking end being used to receive the source signal output by the source output end; and a body, wherein the body and the source docking end are connected by a source line, and the temperature sensing end is detachably mounted on the body.

[0006] Optionally, the signal source output end is fitted with a rotating cylinder, which is driven to rotate by a knob fixedly connected to it. The rotating cylinder has a curved groove, and a limiting post is fixedly connected to the signal source output end. The limiting post slides within the curved groove.

[0007] Optionally, the rotating drum is rotatably connected to a housing, and the housing is fixedly connected to the temperature sensing end.

[0008] Optionally, the dial has a protrusion on the side near the housing, and the housing has a slot on the side near the dial, and the protrusion slides in the slot.

[0009] Optionally, the signal source output terminal and the temperature sensing terminal are connected via a signal source line two.

[0010] Optionally, the end of the signal source output terminal away from the temperature sensing terminal has a signal source docking slot, and the signal source docking terminal has a signal source connector for use with the signal source docking slot.

[0011] Optionally, the signal source docking terminal and the toggle switch are threaded together.

[0012] Optionally, one end of the signal source line is electrically connected to the receiving module of the main body, and the other end is electrically connected to the signal source connector.

[0013] Optionally, the main body is provided with a wiring groove, and the signal source line is disposed in the wiring groove.

[0014] Optionally, a detachable magnetic base is provided on one side of the main body, the outer shell is snapped into the magnetic base, and the signal source docking end is also snapped into the magnetic base.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention features a repositionable signal output terminal. When the temperature sensor and the main body are connected, the signal output terminal extends and inserts into the signal connection terminal, ensuring a secure signal connection and preventing signal transmission problems caused by loose contacts during use. When the temperature sensor and the main body are separated, the signal output terminal retracts, protecting it from damage by impacts.

[0017] This invention features a multi-functional connection method, supporting both wireless and wired connections. When the environmental signal to be detected is turbulent, a wired connection can be used. In this case, the source cable sequentially connects the main body, the source interface, the source output, and the temperature sensor, ensuring efficient and stable signal transmission. For applications requiring short-range wireless communication, a wireless connection can be used. In this case, the user can disconnect the temperature sensor and its source output from the main body and the source interface. Furthermore, this invention also allows the temperature sensor, source output, and source interface to be connected together and mounted on one side of the main body for integrated use, thus achieving multi-functionality and providing more application scenarios for the split-type temperature sensor designed in this invention.

[0027] 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.

[0028] As mentioned earlier, current split-type temperature sensors generally fall into two categories: one uses a wireless communication module for data transmission, and the other connects the main body and the temperature sensing unit together via a signal source line. While the latter type of split-type temperature sensor connected via a signal source line is stable, its temperature sensing unit and signal source line are often connected by threads, and signal transmission is mostly a contact-to-contact connection. Over time, the threads can loosen, causing unstable contact between the contacts responsible for signal transmission, thus leading to malfunctions. To address this, this invention provides a split-type temperature sensor that solves the above problems. This invention solves the problem in the following way.

[0029] Example 1:

[0030] like Figure 1 , Figure 2 As shown, this utility model provides a split-type temperature sensor, which includes a temperature sensing end 1, a signal output end 2, a signal output interface 3, a body 4, and a signal source line 5. The temperature sensing end 1 internally includes at least a temperature sensing element (e.g., thermocouple, thermistor, infrared temperature measurement module), a signal control and processing unit, a wireless signal transmission unit (e.g., Wi-Fi module, Bluetooth module, NFC module, RF module), a wired signal transmission unit, and an energy management unit (e.g., battery). The temperature sensing element measures the temperature of the surrounding environment, while the signal control and processing unit processes and converts the temperature data measured by the temperature sensing element, which is then transmitted by the wireless or wired signal transmission unit. The energy management unit continuously provides the necessary energy for the operation of the temperature sensing end 1. Since all of the above components are common technologies in this field, their technical principles will not be elaborated here.

[0031] The temperature sensor 1 is electrically connected to a signal source output terminal 2. The signal source output terminal 2 acts as an intermediary, responsible for transmitting the signal emitted by the temperature sensor 1 when the wireless signal transmission unit of the temperature sensor 1 is not working but the wired signal transmission unit is working. The signal source output terminal 2 can change its position relative to the temperature sensor 1 to achieve better docking.

[0032] The source interface 3 is used to receive the source signal output from the source output 2. One end of it is connected to the source output 2, and the other end is connected to the main body 4 through the source line 5. Finally, the signal received from the source output 2 through the source interface 3 is transmitted to the inside of the main body 4 through the source line 5, thereby realizing temperature monitoring and management.

[0033] Next, a cable routing groove 16 is provided on the main body 4, and the signal source cable 5 is placed in the cable routing groove 16. This allows the signal source cable 5 to have a place to be accommodated when the main body 4 and the temperature sensing terminal 1 are used as a whole, avoiding the impact or damage to the operation of the device caused by dragging it outside. A detachable magnetic base 17 is provided on one side of the main body 4, and the outer shell 10 and the signal source docking terminal 3 are both snapped into the magnetic base 17. This allows the user to remove the magnetic base 17 and the temperature sensing terminal 1 and the signal source docking terminal 3 together when the temperature sensing terminal 1 and the main body 4 are used separately, and then attach the magnetic base 17 to the place where temperature monitoring is required (or place it directly or snap it in place), thus achieving separate use. Furthermore, the temperature sensing end 1 and the signal source output end 2 can also be separated from the signal source docking end 3 and the signal source cable 5 and used independently for wireless transmission. When in use, the signal source output end 2 and the signal source docking end 3 can be disconnected, and the temperature sensing end 1 and the signal source output end 2 can be placed in the place where temperature detection is required, thereby realizing temperature detection.

[0034] Example 2:

[0035] Based on the above embodiments, in order to provide a clearer and more complete explanation of the technical solutions therein, this utility model also provides an embodiment two. For example... Figure 3 , Figure 4 As shown, in order to achieve the change of position of the signal source output terminal 2 relative to the temperature sensing terminal 1 in the aforementioned embodiments, in this second embodiment, a rotating cylinder 6 is fitted around the signal source output terminal 2. The rotating cylinder 6 is driven to rotate by a knob 7 fixedly connected to it. A curved groove 8 is formed on the rotating cylinder 6, which is opened along the cylindrical surface of the rotating cylinder 6. There is a distance difference between one end of the curved groove 8 and the other end, and this distance difference is parallel to the axis of movement of the signal source output terminal 2. A limiting post 9 is fixedly connected to the signal source output terminal 2, and the limiting post 9 slides within the curved groove 8. Therefore, when the user moves the knob 7, the rotating cylinder 6 rotates relative to the signal source output terminal 2, and the curved groove 8 has a displacement difference on the axis of movement parallel to the signal source output terminal 2, thereby causing the limiting post 9 to slide within the curved groove 8, thereby causing the signal source output terminal 2 to move. The signal source output terminal 2 and the temperature sensing terminal 1 are connected by a signal source line 13. This allows the source output terminal 2 to receive source data transmitted from the temperature sensing terminal 1 even while it is moving.

[0036] The rotating drum 6 is rotatably connected to a housing 10, which is fixedly connected to the temperature sensing terminal 1. Therefore, when the signal source output terminal 2 moves relative to the rotating drum 6, it also moves relative to the temperature sensing terminal 1.

[0037] In order to limit the rotation of the rotating drum 6 relative to the outer casing 10, in this second embodiment, a protrusion 11 (such as...) is provided on the side of the knob 7 near the outer casing 10. Figure 4As shown, a groove 12 is formed on the side of the outer casing 10 near the dial 7, and a protrusion 11 slides within the groove 12. When the protrusion 11 slides from one end of the groove 12 to the other, the limiting post 9 also slides from one end of the curved groove 8 to the other. Simultaneously, the outer casing 10 and the dial 7 are in contact with each other, and a friction layer is provided on both their contact surfaces. This friction layer is made of silicone material or is a granular layer composed of several fine particles. When the dial 7 is turned, causing the rotating cylinder 6 to rotate relative to the outer casing 10, friction is generated between the two friction layers. This friction is sufficient to ensure that no excessive force is required during rotation, and that the dial 7 and the outer casing 10 remain relatively stationary when not rotating, thereby achieving stability of the signal source output terminal 2 adjustment.

[0038] Example 3:

[0039] Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides Embodiment Three. For example... Figure 5 , Figure 6 As shown, in this third embodiment, the end of the signal source output terminal 2 furthest from the temperature sensing terminal 1 has a signal source docking slot 14 (e.g., Figure 5 As shown), the source docking end 3 has a source connector 15 for use with the source docking slot 14. The source docking end 3 and the dial 7 are threaded together. One end of the source line 5 is electrically connected to the receiving module of the main body 4, and the other end is electrically connected to the source connector 15.

[0040] Therefore, in the specific implementation of this utility model, when the temperature sensing end 1 and its source output end 2 and source docking end 3 are disengaged, the limiting post 9 is located at one end of the curved groove 8, and the protrusion 11 is located at the corresponding end of the slot 12. At this time, the source output end 2 retracts into the rotating cylinder 6. When the user needs to connect the temperature sensing end 1 and its source output end 2 and source docking end 3, the user needs to first align the threaded connection of the dial 7 and the source docking end 3, and then simultaneously hold the positions of the outer shell 10 and the source docking end 3, and rotate the dial 7 relative to that position. At this time, under the influence of the threads, the dial 7 and the source docking end 3 are threadedly connected to each other and continuously locked. The source output end 2 also extends under the rotation of the dial 7, locking the source docking groove 14 into the inside of the source connector 15, and the contacts are engaged until the limiting post 9 rotates to the other end of the curved groove 8, and the protrusion 11 also rotates to the corresponding other end of the slot 12. At this point, the temperature sensing end 1, the outer casing 10, the signal source output end 2, and the signal source docking end 3 are mutually fixed. Since the signal source docking slot 14 is engaged inside the signal source connector 15 in this state, it is less likely to fall off compared to the contact-to-contact type signal transmission docking in the prior art. This embodiment achieves stable signal transmission through this method.

[0041] In summary, the present invention, through the above embodiments, possesses advantages over the prior art, including but not limited to the following:

[0042] This invention utilizes a repositionable signal output terminal 2. When the temperature sensing terminal 1 and the main body 4 are connected, the signal output terminal 2 extends and inserts into the signal connection terminal 3, ensuring a stable signal connection and preventing signal transmission problems caused by loose contacts during use. When the temperature sensing terminal 1 and the main body 4 are separated, the signal output terminal 2 retracts, protecting it from damage by impacts.

[0043] This invention features a multi-functional connection method, supporting both wireless and wired connections. When the environmental signal to be detected is turbulent, a wired connection can be used. In this case, the source cable 5 sequentially connects the main body 4, the source docking terminal 3, the source output terminal 2, and the temperature sensing terminal 1, ensuring efficient and stable signal transmission. For applications requiring short-range wireless communication, a wireless connection can be used. In this case, the user can disconnect the temperature sensing terminal 1, along with the source output terminal 2, from the main body 4 and the source docking terminal 3. Furthermore, this invention also allows the temperature sensing terminal 1, the source output terminal 2, and the source docking terminal 3 to be connected together and installed on one side of the main body 4, serving as an integrated unit that works with the main body 4, thus achieving multi-functional use and providing more application scenarios for the split-type temperature sensor designed in this invention.

[0044] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
