Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermometer technology, and in particular to a protective cover for a high-sensitivity thermometer probe. Background Technology
[0002] High-sensitivity thermometer probe protective sleeves are primarily used to protect the probes of high-sensitivity thermometers, ensuring they are not damaged during storage and daily use, and maintaining the thermometer's high-precision detection performance. In various scenarios where thermometers are used, such as in homes and hospitals, the protective sleeve effectively prevents the probe from colliding with external objects and prevents dust and other impurities from adhering, thus ensuring the accuracy of the thermometer's readings. By fitting the thermometer body into the protective sleeve, and utilizing a fitting mechanism and a compression limiting mechanism, stable protection of the probe is achieved. Current devices typically require the following technologies in practical applications:
[0003] 1. Effective limiting technology ensures that the protective sleeve can securely protect the probe under various conditions;
[0004] 2. Excellent sealing technology prevents dust, moisture, etc. from entering the protective sleeve and affecting probe performance;
[0005] 3. The selection of durable materials ensures that the protective case is not easily damaged during long-term use.
[0006] Currently, various protective sleeve devices and methods are used to protect high-sensitivity thermometer probes. Some protective sleeves employ a simple, one-piece molded design made of elastic material, directly slipping onto the thermometer probe and relying on the tension of the elastic material for a snug fit. Other protective sleeves use soft rubber material, protecting the probe by wrapping it around it. Additionally, some protective sleeves incorporate cushioning materials such as sponge inside to reduce the impact of external collisions on the probe.
[0007] However, the above method has a prominent hardware structure problem: the protective case generally lacks a limiting function for the protective state. In actual storage or use, when subjected to external forces such as vibration or shaking, the protective case is prone to relative displacement or even falling off from the probe. For example, during the carrying process, due to daily bumps and vibrations, the protective case may not be able to maintain a tight fit with the probe, causing the probe to be exposed and increasing the risk of damage. Utility Model Content
[0008] To address the shortcomings of existing technologies, this utility model provides a protective cover for a high-sensitivity thermometer probe. It solves the problem that protective covers generally lack a limiting function for the protective state. In actual storage or use, when subjected to external forces such as vibration or shaking, the protective cover is prone to relative displacement or even detachment from the probe. For example, during carrying, due to daily bumps and vibrations, the protective cover may not be able to maintain a tight fit with the probe, causing the probe to be exposed and increasing the risk of damage.
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] A high-sensitivity thermometer probe protective sleeve includes a protective sleeve body. Inside the protective sleeve body is a fitting mechanism for protection, comprising three circular protective sleeves and three rubber sheaths. The three circular protective sleeves are slidably connected inside the protective sleeve body. The three rubber sheaths are respectively disposed on the inner surfaces of the three circular protective sleeves. Inside the protective sleeve body is a threaded mechanism for compression and limiting, comprising an external threaded rod and a hollow frustum-shaped limiting block. The external threaded rod is threaded inside the protective sleeve body, and the hollow frustum-shaped limiting block is fixedly connected to the outer surface of the external threaded rod. The hollow frustum-shaped limiting block is disposed on the outer surface of the three circular protective sleeves. A screw handle is fixedly connected to the end of the external threaded rod away from the hollow frustum-shaped limiting block.
[0011] Preferably, cylindrical connecting blocks are fixedly connected to the outer surfaces of the three circular protective sleeves, and three springs are fixedly connected to the inner surface of the protective sleeve body.
[0012] Preferably, the three springs are fixedly connected to the outer surfaces of the three cylindrical connecting blocks, and the thermometer body is sleeved on the inner surface of the protective sleeve.
[0013] Preferably, the probe body is provided on the outer surface of the thermometer body, and the three rubber sheaths are all provided on the outer surface of the probe body.
[0014] Preferably, a sealing ring is fitted onto the inner surface of the protective sleeve, and the sealing ring is fitted onto the outer surface of the thermometer body.
[0015] Preferably, a high-precision thermistor is provided on the inner surface of the thermometer body, and a high-performance microprocessor is provided on one end of the inner surface of the thermometer body close to the high-precision thermistor.
[0016] Preferably, the thermometer body has a button inside.
[0017] Preferably, a digital display screen is provided inside the thermometer body at one end near the button.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] 1. When in the compression state, hold the handle and turn the external threaded rod to rotate. The external threaded rod is connected to the internal thread of the protective sleeve body. The rotation displacement of the external threaded rod compresses the outer surface of the three circular protective sleeves, ensuring their stability. Even if shaking or vibration occurs during storage, the rubber sheath bonded inside the circular protective sleeves will always be in contact with the probe body surface, preventing the circular protective sleeves from accidentally slipping off during storage and enhancing the stability of the connection between the protective sleeve body and the thermometer body.
[0020] Second, when the three circular protective sleeves are simultaneously squeezed outwards and slide, the three circular protective sleeves will compress the three springs outwards. The elastic force provided by the three springs ensures that the three circular protective sleeves are always in close contact with the probe body surface. This continuous close contact is crucial during the storage of the thermometer, as it ensures that there will be no gaps or loosening between the protective sleeves and the probe.

[0027] This application provides a high-sensitivity thermometer probe protective sleeve, effectively solving the problem of the common lack of limiting function in protective sleeves. In actual storage or use, when subjected to external forces such as vibration or shaking, the protective sleeve is prone to relative displacement or even detachment from the probe. For example, during carrying, due to daily bumps and vibrations, the protective sleeve may not be able to maintain a tight fit with the probe, causing the probe to be exposed and increasing the risk of damage. In the fitted and compressed state, the external threaded rod is rotated by holding the handle and turning it. The external threaded rod is connected to the internal thread of the protective sleeve body. The rotation and displacement of the external threaded rod compresses the outer surface of the three circular protective sleeves, ensuring their stability. Even if shaking or vibration occurs during storage, the rubber sleeves bonded inside the circular protective sleeves can still be kept in contact with the probe body surface, preventing the circular protective sleeves from accidentally slipping off during storage and enhancing the stability of the connection between the protective sleeve body and the thermometer body.
[0028] Example
[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that protective covers generally lack a limiting function for protective states. During actual storage or use, when subjected to external forces such as vibration or shaking, the protective cover is prone to relative displacement or even detachment from the probe. For example, during transport, due to daily bumps and vibrations, the protective cover may not maintain a tight fit with the probe, causing the probe to be exposed and increasing the risk of damage. The overall concept is as follows: a high-sensitivity thermometer probe protective cover, including a protective cover body 11, with a protective cover body 11 internally configured with... The sleeve includes a protective fitting mechanism comprising three annular protective sleeves 12 and three rubber sheaths 16. The three annular protective sleeves 12 are slidably connected inside the protective sleeve body 11. The three rubber sheaths 16 are respectively disposed on the inner surfaces of the three annular protective sleeves 12. The protective sleeve body 11 contains a threaded mechanism for compression and limiting. The threaded mechanism includes an external threaded rod 13 and a hollow frustum-shaped limiting block 14. The external threaded rod 13 is threadedly connected inside the protective sleeve body 11, and the hollow frustum-shaped limiting block 14 is fixedly connected to the outer surface of the external threaded rod 13. A concentric frustum-shaped limiting block 14 is set on the outer surface of the three circular protective sleeves 12. A screw handle 15 is fixedly connected to the end of the external threaded rod 13 away from the concentric frustum-shaped limiting block 14. The thermometer body 19 is fitted onto the surface of the protective sleeve body 11. The lower surface of the thermometer body 19 and the lower probe body 21 will fit against the inner surface of the three circular protective sleeves 12. The three circular protective sleeves 12 are pushed outward simultaneously to compress and slide. All three circular protective sleeves 12 are in contact with the inner surface of the probe body 21 through the rubber sleeve 16, providing shielding and protection. When in a close-fitting and compressed state, the external threaded rod 13 is rotated by holding the screw handle 15. The external threaded rod 13 is connected to the internal thread of the protective sleeve body 11. The rotational displacement of the external threaded rod 13 compresses the outer surface of the three circular protective sleeves 12, ensuring their stability. Even if shaking or vibration occurs during storage, the rubber sheath 16 bonded inside the circular protective sleeve 12 can still be kept in contact with the surface of the probe body 21, preventing the circular protective sleeve 12 from slipping off accidentally during storage, and enhancing the stability of the connection between the protective sleeve body 11 and the thermometer body 19.
[0030] Three circular protective sleeves 12 are fixedly connected to cylindrical connecting blocks 17 on their outer surfaces. Three springs 18 are fixedly connected to the inner surface of the protective sleeve body 11. The three springs 18 are respectively fixedly connected to the outer surfaces of the three cylindrical connecting blocks 17. A thermometer body 19 is fitted onto the inner surface of the protective sleeve body 11. A probe body 21 is set on the outer surface of the thermometer body 19. Three rubber sleeves 16 are set on the outer surface of the probe body 21. A sealing ring 22 is fitted onto the inner surface of the protective sleeve body 11. When the three circular protective sleeves 12 are simultaneously squeezed outward and slide, the three circular protective sleeves 12 will squeeze the three springs 18 outward and contract. The elastic force provided by the three springs 18 ensures that the three circular protective sleeves 12 are always tightly fitted to the surface of the probe body 21. The sealing ring 22 fitted onto the inner surface of the protective sleeve body 11 and the outer surface of the thermometer body 19 will ensure the sealing of the fitting and block dust when not in use.
[0031] A sealing ring 22 is fitted onto the outer surface of the thermometer body 19. A high-precision thermistor 23 is installed on the inner surface of the thermometer body 19. A high-performance microprocessor 24 is installed at one end of the inner surface of the thermometer body 19 near the high-precision thermistor 23. A button 25 is installed inside the thermometer body 19. A digital display screen 26 is installed at one end of the thermometer body 19 near the button 25. When the probe body 21 is placed at the user's temperature measurement position, the body temperature detected by the probe body 21 will be directly converted into an electrical signal and displayed on the digital display screen 26. Before using the thermometer body 19, the user needs to press the button 25 to control the on / off state of the thermometer body 19. The high-precision thermistor 23 and high-performance microprocessor 24 installed inside the thermometer body 19 enable the thermometer body 19 to detect high sensitivity. The high-precision thermistor 23 is responsible for accurately sensing temperature changes and converting them into resistance value changes, while the high-performance microprocessor 24 performs precise processing and analysis of these changes. The combination of the two enables the thermometer body 19 to quickly and accurately convert the tiny resistance changes detected by the high-precision thermistor 23 into high-precision temperature measurement values. The converted measurement values are displayed on the digital display screen 26, which greatly improves the thermometer body 19's ability to detect subtle changes in human body temperature and achieves high-sensitivity measurement.
[0032] To address the problems existing in the prior art, this utility model provides a high-sensitivity thermometer probe protective sleeve. When in a close-fitting and compressed state, the external threaded rod 13 is rotated by holding and turning the handle 15. The external threaded rod 13 is internally threaded with the protective sleeve body 11. The rotational displacement of the external threaded rod 13 compresses the outer surface of the three circular protective sleeves 12, ensuring their stability. Even if shaking or vibration occurs during storage, the rubber sheath 16 bonded inside the circular protective sleeves 12 can still be kept in contact with the probe body 21 surface, preventing the circular protective sleeves 12 from accidentally slipping off during storage, thus enhancing the stability of the connection between the protective sleeve body 11 and the thermometer body 19.
[0033] Protective cover body 11: As the main frame of the entire protective cover, it provides installation space for internal fitting mechanism, thread mechanism and other components. At the same time, it fits the thermometer body 19 and provides overall protection for the thermometer. In conjunction with other internal components, it ensures that external dust and other impurities are blocked when the thermometer body 19 and the probe body 21 are protected when the thermometer body is not in use.
[0034] Circular protective sleeve 12: It works in conjunction with the rubber sheath 16. When the thermometer body 19 is fitted into the protective sleeve body 11, it protects the probe body 21 by adhering to the inner surface of the probe body 21. Under the action of external force, it can slide inside the protective sleeve body 11 and is connected to the cylindrical connecting block 17. With the help of the elastic force of the spring 18, it always adheres tightly to the surface of the probe body 21. Under the action of the threaded mechanism, it can also ensure its stable state inside the protective sleeve body 11 and prevent accidental slippage during storage.
[0035] Rubber sleeve 16: It is pasted on the inner surface of the circular protective sleeve 12 and directly contacts the surface of the probe body 21, providing soft and close protection, avoiding direct hard contact between the probe body 21 and the circular protective sleeve 12 to prevent damage, and enhancing the protection effect on the probe body 21.
[0036] External thread rod 13: It is connected to the internal thread of the protective sleeve body 11. By holding the screw handle 15 and rotating the external thread rod 13, the rotational displacement of the external thread rod 13 is used to squeeze the hollow frustum-shaped limiting block 14, thereby indirectly squeezing the outer surface of the three circular protective sleeves 12. This ensures that the circular protective sleeves 12 are in a stable state inside the protective sleeve body 11, preventing them from accidentally slipping off due to shaking or vibration during storage, and enhancing the stability of the connection between the protective sleeve body 11 and the thermometer body 19.
[0037] Hollow frustum-shaped limiting block 14: It is fixedly connected to the outer surface of the external thread rod 13. When the external thread rod 13 rotates, it moves with the external thread rod 13 and transmits the extrusion force of the external thread rod 13 to the three circular protective sleeves 12. It plays a limiting and extrusion role on the circular protective sleeves 12 and helps maintain the stable position of the circular protective sleeves 12 in the protective sleeve body 11.
[0038] Turning handle 15: Connected to the end of the external threaded rod 13 away from the hollow frustum-shaped limiting block 14, making it convenient for the user to hold and rotate it to drive the external threaded rod 13 to rotate, thereby realizing the compression and limiting operation of the annular protective sleeve 12 and enhancing the stability of the connection between the protective sleeve and the thermometer.
[0039] Cylindrical connecting block 17: Fixed on the outer surface of the annular protective sleeve 12 and connected to the spring 18 on the inner surface of the protective sleeve body 11. When the annular protective sleeve 12 is pushed outward and slid, it drives the spring 18 to contract. With the help of the elastic force of the spring 18, the annular protective sleeve 12 is always in close contact with the surface of the probe body 21.
[0040] Spring 18: One end is fixed to the inner surface of the protective sleeve body 11, and the other end is connected to the cylindrical connecting block 17. It contracts when the annular protective sleeve 12 slides and is squeezed, providing elasticity to the annular protective sleeve 12 and ensuring that the three annular protective sleeves 12 are always in close contact with the surface of the probe body 21, thus ensuring the protection effect of the probe body 21.
[0041] Sealing ring 22: It is fitted on the inner surface of the protective sleeve body 11 and the outer surface of the thermometer body 19 to ensure the sealing of the fitting. When not in use, it prevents dust and other impurities from entering the interior of the protective sleeve, prevents dust from affecting the performance of the probe body 21, and works with other components to maintain the cleanliness and stable working environment of the probe body 21.
[0042] High-precision thermistor 23: Installed on the inner surface of the thermometer body 19, it is responsible for accurately sensing temperature changes and converting temperature changes into resistance changes, providing basic data for the thermometer body 19 to achieve high-sensitivity detection;
[0043] High-performance microprocessor 24: Located on the inner surface of the thermometer body 19 near one end of the high-precision thermistor 23, it accurately processes and analyzes the resistance value changes detected by the high-precision thermistor 23. Working closely with the high-precision thermistor 23, it converts minute resistance changes into high-precision temperature measurement values, greatly improving the ability of the thermometer body 19 to detect subtle changes in human body temperature.
[0044] Button 25: Button 25 has a simple circuit connection structure inside. When the user presses button 25, the conductive parts inside button 25 contact or separate from each other, thereby changing the on / off state of the circuit. This on / off signal will be transmitted to the control circuit inside the thermometer body 19. After receiving the signal, the control circuit starts or stops the various working processes of the thermometer according to the preset logic, thereby controlling the on / off state of the thermometer body 19.
[0045] Digital display screen 26: The digital display screen 26 adopts technologies such as light-emitting diode (LED) display. The high-performance microprocessor 24 outputs the processed high-precision temperature measurement value to the digital display screen 26 in the form of a digitally encoded signal. The driving circuit inside the display screen controls the corresponding display unit (LED) to emit light or change color according to the received digitally encoded signal, so as to intuitively present the temperature value in digital form, making it convenient for users to read their body temperature.
[0046] Working principle:
[0047] The first step is to place the probe body 21 at the user's temperature measurement position. The body temperature detected by the probe body 21 will be directly converted into an electrical signal and displayed on the digital display screen 26. Before using the thermometer body 19, the user needs to press the button 25 to control the on / off operation of the thermometer body 19. The high-precision thermistor 23 and high-performance microprocessor 24 installed in the thermometer body 19 enable the thermometer body 19 to detect high sensitivity. The high-precision thermistor 23 is responsible for accurately sensing temperature changes and converting them into resistance value changes, while the high-performance microprocessor 24 accurately processes and analyzes these changes. The combination of the two enables the thermometer body 19 to quickly and accurately convert the tiny resistance changes detected by the high-precision thermistor 23 into high-precision temperature measurement values. The converted measurement values will be displayed on the digital display screen 26, which greatly improves the thermometer body 19's ability to detect subtle changes in human body temperature and achieves high-sensitivity measurement.
[0048] The second step involves protecting the thermometer body 19 after use when it is idle. This is achieved by attaching a protective sleeve 11 to the thermometer body 19. The lower surface of the thermometer body 19 and the probe body 21 at the lower end will adhere to the inner surface of the three annular protective sleeves 12. Simultaneously pushing and squeezing the three annular protective sleeves 12 outwards causes them to slide. As the three annular protective sleeves 12 slide outwards, they compress the three springs 18, ensuring a tight fit between the three annular protective sleeves 12 and the probe body 21. The sealing ring 22, which is fitted onto the inner surface of the protective sleeve 11 and the outer surface of the thermometer body 19, further contributes to this protection. This design ensures the sealing of the connection point and blocks dust during storage. The three circular protective sleeves 12 are all in contact with the inner surface of the probe body 21 through the rubber sleeves 16, providing protection. When in a pressed state, the external thread rod 13 is rotated by holding the screw handle 15. The external thread rod 13 is connected to the internal thread of the protective sleeve body 11. The rotation and displacement of the external thread rod 13 presses the outer surface of the three circular protective sleeves 12, ensuring their stability. Even if shaking or vibration occurs during storage, the rubber sleeves 16 bonded inside the circular protective sleeves 12 will always be in contact with the surface of the probe body 21, preventing the circular protective sleeves 12 from slipping off accidentally during storage and enhancing the stability of the connection between the protective sleeve body 11 and the thermometer body 19.
[0049] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
