Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a temperature sensor structure. Background Technology

[0002] In the field of liquid heating equipment, the container heating base is a core component for maintaining a constant temperature of the liquid inside the container, and its performance directly affects the user experience and the safety of the equipment. Especially in applications with high temperature control requirements, such as infant feeding, home cooking, and scientific experiments, the heating base needs to be able to accurately and stably control the temperature of the liquid inside the container.

[0003] Currently, most heating bases on the market integrate temperature sensors to monitor the temperature at the bottom of the container in real time and automatically adjust the heating power according to preset conditions, thereby ensuring that the liquid inside the container remains within the ideal temperature range. However, in practical applications, a prominent problem has gradually emerged: poor contact between the sensor and its housing due to the sensor's inherent dimensional instability. This poor contact not only reduces thermal conductivity, causing temperature readings to deviate, but also further affects the accuracy and stability of the heating base in maintaining a constant liquid temperature, and may even adversely impact the safety and lifespan of the equipment. Utility Model Content

[0004] The purpose of this invention is to disclose a sensor that solves the problem of poor contact between the sensor and the housing.

[0005] To achieve the above objectives, this utility model discloses a temperature sensor structure, comprising: a temperature sensing housing having a receiving groove; a limiting frame connected to the temperature sensing housing, with a portion of the limiting frame extending into the receiving groove to form an abutment platform; a single-ended output temperature sensing device including a sensing head and two transmission lines located at one end of the sensing head, the other end of the sensing head abutting the receiving groove, and the two transmission lines passing through the limiting frame; and an elastic element disposed between the sensing head and the abutment platform, for providing the sensing head with a force abutting towards the receiving groove.

[0006] By adopting the above scheme, the limiting bracket and the temperature sensing housing provide stable support and positioning for the temperature sensing device, ensuring the correct position of the sensing device within the housing. The elastic element provides a force to the sensing head towards the receiving groove, thereby ensuring a tight contact between the sensing head and the temperature sensing housing at all times. This design cleverly solves the problem of poor contact caused by changes in sensor model. Regardless of the sensor model, as long as its sensing head can be placed into the receiving groove of the temperature sensing housing, the elastic element can use its elastic force to firmly press the sensing head against the receiving groove, ensuring good thermal conductivity and accurate temperature readings.

[0007] Furthermore, the elastic element includes: a first abutment position located at one end of the elastic element, and one end of the sensing head abutting against the first abutment position; and a clearance groove disposed on both sides of the first abutment position and extending toward the limiting frame to avoid the transmission line.

[0008] By adopting the above solution, the elastic element, due to its inherent elasticity, allows the first contact point to adjust its contact with the sensing head when replacing sensors of different models but similar dimensions. This ensures appropriate contact force is provided to the sensing head, preventing poor contact due to sensor model changes and enhancing the versatility and adaptability of the temperature sensor structure. The avoidance groove prevents the transmission line from being squeezed or worn by the elastic element during installation and use. This helps protect the integrity of the transmission line, preventing signal transmission interruption or instability caused by transmission line damage, thus ensuring the normal operation of the temperature sensor.

[0009] Furthermore, a limiting groove is provided at the other end of the elastic element, and a limiting slide rod is provided on the abutment platform along the axial direction, the limiting slide rod sliding along its axial direction in the limiting groove.

[0010] By adopting the above scheme, the cooperation between the limiting slide rod and the limiting slide groove can limit the displacement of the elastic element in the horizontal direction, i.e., perpendicular to the axial direction, ensuring that the elastic element is always compressed or extended along the axial direction. This prevents the elastic element from shifting or tilting due to uneven force, thereby ensuring stable contact between the sensing head and the temperature sensing housing and maintaining good heat conduction. When the equipment is subjected to external forces such as vibration or shaking, the cooperation between the limiting slide rod and the limiting slide groove can effectively prevent the elastic element from loosening or falling off, ensuring that the temperature sensor structure can work normally and reliably.

[0011] Furthermore, the other end of the elastic member is provided with an abutting lip, which abuts against the abutting platform, and the abutting lip has an elastic deformation force that returns to the side away from the abutting platform.

[0012] By adopting the above solution, the contact lip possesses elastic deformation force, providing additional elastic support to the entire structure while the elastic component is functioning normally. This support further ensures stable contact pressure between the sensor head and the temperature sensing housing, making temperature measurement more accurate and reliable. When the equipment is subjected to external impacts, vibrations, or thermal expansion and contraction caused by temperature changes, the elastic deformation force of the contact lip acts as a buffer. It absorbs and releases some energy, reducing the impact and vibration effects on the internal components of the temperature sensor, preventing damage to components due to excessive force, and ensuring stable operation of the temperature sensor even in complex environments.

[0013] Furthermore, the side wall of the contact platform is provided with a first snap-fit ​​part, and the side wall of the temperature sensing shell is provided with a second snap-fit ​​part, and the first snap-fit ​​part and the second snap-fit ​​part snap-fit ​​together.

[0014] By adopting the above solution, the assembly process of the contact platform and the temperature sensing housing becomes extremely simple. Installers do not need to use additional tools; they only need to align the contact platform and the temperature sensing housing, and with a simple pressing or pushing motion, the two locking parts can quickly snap together, greatly shortening the installation time and improving production efficiency.

[0015] Furthermore, in the first and second locking parts, one is an outwardly protruding locking block, and the other is an inwardly recessed slot, which engages with the locking block.

[0016] By adopting the above solution, the shape design of the locking block and the slot provides a clear guiding function. During assembly, the installer only needs to roughly align the locking block with the slot, and the outline of the locking block will guide it smoothly into the slot, achieving quick and accurate locking and positioning. No complex tools or special training are required; a simple pressing or pushing action is all that's needed to complete the locking process, providing great convenience to users and enhancing the user experience. It also reduces the difficulty of installation and the skill requirements for operators, improving installation efficiency, and is particularly suitable for large-scale production environments, effectively shortening the product production cycle.

[0017] Furthermore, a slide is provided on the side of the slot facing the card block, and a slope is provided on the side of the card block facing the slot.

[0018] By adopting the above scheme, a natural guiding mechanism is formed during installation. The slide provides a clear sliding path for the locking block, while the slope of the locking block acts as a guide ramp, allowing it to gradually slide in along the direction of the slide, avoiding direct collision and jamming between the locking block and the edge of the slot, and reducing the force required during installation.

[0019] Furthermore, a hemispherical or semi-ellipsoidal sensing head groove is provided at the end of the receiving groove away from the limiting frame, and the sensing head abuts in the sensing head groove.

[0020] By adopting the above scheme, the hemispherical or semi-ellipsoidal sensor head slot has a smooth curved surface, enabling more uniform contact between the sensor head and the inner wall of the slot. Compared to flat surfaces or other irregular shapes, this curved surface contact ensures that there are no obvious contact gaps or stress concentration points between the sensor head and the sensor head slot, allowing heat to be transferred more evenly from the temperature sensing shell to the sensor head. This improves the accuracy of temperature measurement, enabling a more precise reflection of the actual temperature at the bottom of the container, meeting the needs of various applications requiring high temperature measurement accuracy, such as precision laboratory experiments and temperature control in high-end baby products.

[0021] Furthermore, an auxiliary temperature sensing device is also provided inside the limiting frame to detect the ambient temperature inside the limiting frame.

[0022] By adopting the above solution, the accuracy of temperature measurement is significantly improved, ensuring that the temperature sensor can provide reliable measurement data under different ambient temperatures, meeting the application scenarios with high requirements for temperature measurement accuracy; at the same time, it helps to detect potential equipment failures in advance, carry out timely maintenance and repair, avoid equipment damage due to overheating and other reasons, extend the service life of the equipment, and reduce maintenance costs.

[0023] Furthermore, the limiting frame is fitted with a sleeve, the inner wall of the sleeve is provided with an axial limiting groove, and the outer surface of the limiting frame is provided with limiting ribs corresponding to the limiting groove.

[0024] By adopting the above solution, the cooperation between the limiting groove and the limiting rib provides precise guidance for the movement of the limiting frame within the sleeve, making sleeve installation more convenient.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] 1. An elastic element is positioned between the sensing head and the contact platform, providing the sensing head with a force that abuts against the receiving groove. Regardless of the sensor model, as long as the sensing head can be placed into the receiving groove of the temperature sensing housing, the elastic element can use its elastic force to tightly abut the sensing head against the receiving groove. This effectively solves the problem of poor contact between the sensor and the sensor housing caused by changes in the sensor model, avoids reduced heat conduction efficiency and temperature reading deviation caused by poor contact, and improves the accuracy of temperature measurement.

[0027] 2. The elastic element can continuously provide resistance, compensating for the loosening between the sensor and the housing caused by factors such as vibration and wear, ensuring that the temperature sensor maintains good thermal conductivity and temperature measurement stability throughout its service life, reducing equipment failure and maintenance costs caused by poor contact;

[0028] 3. The tight contact between the sensor head and the temperature sensing shell reduces thermal resistance, allowing heat to be transferred from the bottom of the container to the sensor head more quickly and effectively. This enables the temperature sensor to more accurately sense the temperature at the bottom of the container, improving the accuracy of temperature measurement and meeting the needs of applications with high temperature control requirements, such as infant feeding, home cooking, and scientific experiments.

[0029] 4. Good contact and accurate temperature measurement can avoid equipment failure and safety hazards caused by excessively high or low temperatures, extend the service life of the equipment, reduce the probability of equipment failure and safety accidents, and protect the personal and property safety of users.

[0041] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0042] Please refer to Embodiment 1 of this utility model. Figures 1 to 4As shown, a temperature sensor structure is provided, including a temperature sensing housing 1, a limiting frame 2, a single-ended output temperature sensing device 3, and an elastic element 4. The temperature sensing housing 1 is made of glass or thermally conductive metal, and has a hollow interior forming a receiving groove 11. One end of the receiving groove 11 can be connected to the limiting frame 2. The connection between the temperature sensing housing 1 and the limiting frame 2 includes, but is not limited to, snap-fit, welding, bonding, or screwing. In this embodiment 1, the temperature sensing housing 1 is bullet-shaped, and the internal receiving groove 11 is also bullet-shaped. The limiting frame 2, after being connected to the temperature-sensing housing, extends partially into the receiving groove 11 to form an abutment platform 21. The single-ended output temperature sensing device 3 includes a sensing head 31 and two transmission lines 32 located at one end of the sensing head 31. The other end of the sensing head 31 abuts against the deepest part of the receiving groove 11. The two transmission lines 32 pass through the limiting frame 2. The elastic element 4 is disposed between the sensing head 31 and the abutment platform 21 to provide the sensing head 31 with a force abutting against the receiving groove 11. The limiting frame 2 and the temperature-sensing housing 1 provide stable support and positioning for the temperature sensing device, ensuring the correct position of the sensing device within the temperature-sensing housing 1. The function of the elastic element 4 is to provide the sensing head 31 with a force abutting against the receiving groove 11, thereby ensuring that the sensing head 31 and the temperature-sensing housing 1 always maintain a tight contact. This design cleverly solves the problem of poor contact caused by changes in sensor model. Regardless of the sensor model, as long as its sensing head 31 can be placed into the receiving groove 11 of the temperature sensing housing 1, the elastic member 4 can use its elastic force to tightly abut the sensing head 31 against the receiving groove 11, ensuring good thermal conductivity and accurate temperature readings.

[0043] In some embodiments, the elastic member 4 includes a first abutment position 41 and a clearance groove 42. The first abutment position 41 is located at one end of the elastic member 4, and one end of the sensing head 31 abuts against the first abutment position 41. The clearance groove 42 is disposed on both sides of the first abutment position 41 and extends towards the limiting frame 2 to avoid the transmission line 32. Because the elastic member 4 has a certain degree of elasticity, when replacing sensors of different models but similar sizes, the first abutment position 41 of the elastic member 4 can still adjust its contact state with the sensing head 31 through its own elasticity, ensuring that it provides a suitable abutment force to the sensing head 31 and avoiding poor contact due to changes in sensor model. This enhances the versatility and adaptability of the temperature sensor structure. The clearance groove 42 prevents the transmission line 32 from being squeezed or worn by the elastic member 4 during installation and use. This helps protect the integrity of the transmission line 32, avoiding signal transmission interruption or instability caused by damage to the transmission line 32, thereby ensuring that the temperature sensor can work normally.

[0044] In some embodiments, to improve the contact stability between the elastic element 4 and the abutment platform 21, a limiting groove 43 is provided at the other end of the elastic element 4, and a limiting slide rod 211 is provided on the abutment platform 21 along the axial direction. The limiting slide rod 211 slides along its axial direction within the limiting groove 43. The cooperation between the limiting slide rod 211 and the limiting groove 43 can limit the displacement of the elastic element 4 in the horizontal direction, i.e., perpendicular to the axial direction, ensuring that the elastic element 4 is always compressed or extended along the axial direction, avoiding the elastic element 4 from shifting or tilting due to uneven force, thereby ensuring stable contact between the sensing head 31 and the temperature sensing housing 1 and maintaining good heat conduction. When the equipment is subjected to external forces such as vibration or shaking, the cooperation between the limiting slide rod 211 and the limiting groove 43 can effectively prevent the elastic element 4 from loosening or falling off, ensuring that the temperature sensor structure can work normally and reliably.

[0045] In this embodiment 1, the elastic element 4 is made of silicone and is bullet-shaped. The other end of the elastic element 4 has an abutment lip 44, which abuts against the abutment platform 21. The abutment lip 44 has an elastic deformation force that allows it to return to its original position away from the abutment platform 21. Because the abutment lip 44 is made of silicone, a cavity is formed between it and the abutment platform 21. When subjected to compressive force, the cavity allows it to automatically return to its original position. The elastic deformation force of the abutment lip 44 provides additional elastic support to the entire structure when the elastic element 4 is working normally. This support further ensures a stable contact pressure between the sensor head 31 and the temperature sensing housing 1, making temperature measurement more accurate and reliable. When the device is subjected to external impacts, vibrations, or temperature changes causing thermal expansion and contraction, the elastic deformation force of the abutment lip 44 can act as a buffer. It can absorb and release some energy, reducing the impact and vibration on the internal components of the temperature sensor, preventing damage to the components due to excessive force, and ensuring that the temperature sensor can still work stably in complex environments.

[0046] It should be noted that in other embodiments, the shapes of the temperature sensing shell 1, the receiving groove 11 and the elastic member 4 are not limited, as long as they can be adapted to each other to maintain the continuous contact effect between the single-end output temperature sensing device 3 and the deepest part of the receiving groove 11.

[0047] In some embodiments, the abutment platform 21 and the temperature sensing housing 1 are assembled by a snap-fit ​​method. Specifically, the side wall of the abutment platform 21 is provided with a first snap-fit ​​part 212, and the side wall of the temperature sensing housing 1 is provided with a second snap-fit ​​part 12. The first snap-fit ​​part 212 and the second snap-fit ​​part 12 snap together, making the assembly process of the abutment platform 21 and the temperature sensing housing 1 extremely simple. Installers do not need additional tools; they only need to align the abutment platform 21 and the temperature sensing housing 1, and with a simple pressing or pushing action, the two snap-fit ​​parts can quickly snap together, greatly shortening the installation time and improving production efficiency. Preferably, of the first snap-fit ​​part 212 and the second snap-fit ​​part 12, one is an outwardly protruding snap block 2121, and the other is a concave slot 121. The slot 121 snaps with the snap block 2121, and the shape design of the snap block 2121 and the slot 121 has a clear guiding function. During assembly, the installer only needs to roughly align the locking block 2121 with the slot 121. The outline of the locking block 2121 will guide it smoothly into the slot 121, achieving quick and precise locking and positioning. No complicated tools or special training are required; a simple pressing or pushing action is all that's needed to complete the locking process, providing great convenience and enhancing the user experience. It also reduces the difficulty of installation and the skill requirements for operators, improving installation efficiency. It is particularly suitable for large-scale production environments, effectively shortening the product production cycle.

[0048] In this embodiment 1, the first latching part 212 is a latching block 2121, and the second latching part 12 is a slot 121. The slot 121 penetrates the side wall of the temperature-sensing housing 1, and the slot 121 allows the receiving groove 11 to communicate with the outside through the slot 121. In the inner wall of the receiving groove 11, a slide rail 13 is formed at the end of the slot 121 near the elastic member 4, which is arranged along the axial direction of the temperature-sensing housing 1. The latching block 2121 has a slope 2122 on the side facing the temperature-sensing housing 1, forming a natural guiding mechanism during installation. The slide rail 13 provides a clear sliding path for the latching block 2121, while the slope 2122 of the latching block 2121 acts as a guide ramp, allowing it to gradually slide in along the direction of the slide rail 13, avoiding direct collision and jamming between the latching block 2121 and the edge of the slot 121, and reducing the force required during installation. At the same time, when the locking block 2121 is engaged with the slot 121, it can prevent detachment. The side of the locking block 2121 facing away from the slope 2122 abuts against the edge of the slot 121, improving the engagement stability.

[0049] In some embodiments, to further improve the contact area between the sensing head 31 and the sensing head groove 14, i.e., the heat conduction effect between the sensing head 31 and the temperature sensing shell 1, a hemispherical or semi-ellipsoidal sensing head groove 14 is provided at the end of the receiving groove 11 away from the limiting frame 2, i.e., it is located at the deepest part of the receiving groove 11. The sensing head 31 abuts against the sensing head groove 14. The hemispherical or semi-ellipsoidal sensing head groove 14 has a smooth curved surface, enabling the sensing head 31 to achieve more uniform contact with the inner wall of the groove. Compared to flat surfaces or other irregular shapes, this curved surface contact ensures that there are no obvious contact gaps or stress concentration points between the sensing head 31 and the sensing head groove 14, allowing heat to be transferred more evenly from the temperature sensing shell 1 to the sensing head 31. This improves the accuracy of temperature measurement, enabling more precise reflection of the actual temperature at the bottom of the container, meeting the needs of various applications requiring high temperature measurement accuracy, such as precision laboratory experiments and temperature control for high-end baby products.

[0050] In some embodiments, optionally, an auxiliary temperature sensing device 5 may also be provided within the limiting frame 2 to detect the ambient temperature within the limiting frame 2. This can significantly improve the accuracy of temperature measurement, ensuring that the temperature sensor can provide reliable measurement data under different ambient temperatures, meeting the application scenarios with high requirements for temperature measurement accuracy; at the same time, it helps to detect potential equipment failures in advance, enabling timely maintenance and repair, avoiding equipment damage due to overheating or other reasons, extending the service life of the equipment, and reducing maintenance costs.

[0051] In some embodiments, the limiting frame 2 is fitted with a sleeve 6, the inner wall of the sleeve 6 is provided with an axial limiting groove 61, and the outer surface of the limiting frame 2 is provided with a limiting rib 22 corresponding to the limiting groove 61. The cooperation between the limiting groove 61 and the limiting rib 22 provides precise guidance for the movement of the limiting frame 2 within the sleeve 6, making the installation of the sleeve 6 more convenient.

[0052] During assembly, the limiting groove 43 of the elastic element 4 is fitted onto the limiting rod 211 of the limiting frame 2. The transmission line 32 of the single-end output temperature sensing device 3 passes through the clearance groove 42 and the limiting frame 2. The sensing head is pressed into the first abutment position 41 of the elastic element 4. Then, the elastic element 4, together with the single-end output temperature sensing device 3, is installed onto the limiting frame 2. Finally, the limiting frame 2 is aligned with the receiving groove 11 of the temperature sensing housing 1 for installation until the locking block 2121 of the limiting frame 2 is aligned with the slot 121 of the temperature sensing housing 1 to complete the locking.

[0053] Embodiment 2 of this utility model modifies the elastic element 4 based on Embodiment 1. The elastic element 4 is a spring, and the design of the abutment lip 44 is eliminated, so that the other end of the elastic element 4 directly abuts against the abutment platform 21. One end of the spring forms a natural limiting groove 43, which can be directly sleeved on the limiting slide rod 211 to ensure the stability of spring compression. The other end of the spring abuts against one end of the sensing head 31 to form the first abutment position 41 of the spring. Preferably, the design of the other end of the spring can ensure a perfect fit with the sensing head 31, and it is not advisable for the sensing head 31 to detach during the process of providing elastic force to the sensing head 31. The two transmission lines 32 of the sensing head 31 can pass directly through the spring, which can also avoid the influence of wiring.

[0054] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0055] 1. The elastic element 4 is disposed between the sensing head 31 and the abutment stage 21, which can provide the sensing head 31 with abutting force in the direction of the receiving groove 11. No matter how the sensor model changes, as long as the sensing head 31 can be placed into the receiving groove 11 of the temperature sensing housing 1, the elastic element 4 can use its elastic force to tightly abut the sensing head 31 against the receiving groove 11, which effectively solves the problem of poor contact between the sensor and the sensor housing caused by the change of the sensor model, avoids the reduction of thermal conductivity and temperature reading deviation caused by poor contact, and improves the accuracy of temperature measurement.

[0056] 2. The elastic element 4 can continuously provide a resisting force to compensate for the loosening between the sensor and the housing caused by factors such as vibration and wear, ensuring that the temperature sensor maintains good thermal conductivity and temperature measurement stability throughout its service life, reducing equipment failure and maintenance costs caused by poor contact;

[0057] 3. The tight contact between the sensor head 31 and the temperature sensing shell 1 can reduce thermal resistance, allowing heat to be transferred from the bottom of the container to the sensor head 31 more quickly and effectively; thus enabling the temperature sensor to more accurately sense the temperature at the bottom of the container, improving the accuracy of temperature measurement, and meeting the application scenarios with high temperature control requirements, such as infant feeding, home cooking, and scientific experiments.

[0058] 4. Good contact and accurate temperature measurement can avoid equipment failure and safety hazards caused by excessively high or low temperatures, extend the service life of the equipment, reduce the probability of equipment failure and safety accidents, and protect the personal and property safety of users.

[0059] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
