Description

Technical Field

[0001] This utility model relates to the field of ear thermometer technology, and in particular to an ear thermometer with an adjustable temperature measuring head. Background Technology

[0002] An ear thermometer is an electronic instrument that measures human ear temperature using infrared technology, primarily for rapid body temperature detection. Its principle is based on detecting infrared energy in the eardrum region and assessing core body temperature by referring to the location of blood vessels connected to the hypothalamus.

[0003] Existing ear thermometers typically employ a one-piece or fixed-angle design, where the angle between the probe and the main handle remains constant. This traditional structure has gradually revealed several limitations in practical applications:

[0004] Significant individual differences exist in the physiological structure of the external auditory canal among different users (e.g., the diameter and curvature of the adult ear canal differ from those of an infant). Furthermore, the optimal insertion angle of the device varies considerably depending on whether the user is measuring themselves or others. A fixed-angle probe struggles to adapt to these differences. To accurately align the probe with the tympanic membrane, users often need to use awkward wrist and arm postures to accommodate the device. This not only requires strenuous operation but also greatly increases the risk of the probe failing to align with the tympanic membrane and instead touching the ear canal wall, introducing significant measurement errors and affecting the reliability of the results.

[0005] Even under ideal conditions, the fixed-angle design limits the device's versatility. Users cannot adjust the device according to their most comfortable and natural grip habits. This "device adapts to person" rather than "person adapts to device" interaction method reduces the user experience, especially in clinical environments where frequent and rapid measurements are required, and increases operational fatigue for medical staff.

[0006] Therefore, further improvements are needed. To this end, we have proposed an ear thermometer with an adjustable temperature sensor. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable ear thermometer.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable ear thermometer, comprising an ear thermometer body, an assembly base fixedly connected to the top of the ear thermometer body, mounting grooves provided on both sides of the inner wall of the assembly base, spring brake rings fixedly installed on one side of the inner wall of each of the two mounting grooves, and brake shafts rubbing against each of the two spring brake rings.

[0009] One end of each of the two spring brake rings is fixedly connected to a bearing housing, and the inner ring of the bearing housing is fixedly connected to the brake shaft.

[0010] Two deflection angle limiting blocks are symmetrically fixedly connected to adjacent sides of the outer surface of the two bearing housings;

[0011] Both brake shafts are fixedly connected to a movable seat, and a temperature measuring head body is fixedly connected to the top of the movable seat;

[0012] The ear thermometer has a matching pen cap on its upper part.

[0013] Furthermore, both of the spring brake rings include a connecting seat, which is fixedly connected to the mounting groove. A fixing ring is fixedly connected to one side of the outer surface of the connecting seat, and the fixing ring is fixedly connected to the seat body of the bearing seat, providing a reliable mounting base for the braking function.

[0014] Furthermore, a spring body is sleeved on the outer surface of the fixed ring, and the spring body is fixedly connected to the connecting seat. The other end of the spring body is fixedly connected to a brake ring body, and the brake ring body is slidably sleeved on the outer surface of the bearing seat, using the preload of the spring to provide a continuous and uniform clamping force to the brake ring body.

[0015] Furthermore, both brake shafts include a support shaft, and the support shaft is fixedly connected to the inner ring of the bearing in the bearing housing. One end of the support shaft is fixedly connected to a brake disc, and the brake disc rubs against the brake ring body and is fixedly connected to the movable seat. A stop block is fixedly connected to the brake disc on one side of the support shaft. This structure converts the rotational motion into planar friction between the brake disc and the brake ring body, which has a large torque and reliable locking.

[0016] Furthermore, the pen cap matches the temperature measuring head body and is fastened to the ear thermometer body. When not in use, the pen cap provides all-round protection for the precision temperature measuring head, effectively preventing dust and impacts, and extending the product's service life.

[0017] Furthermore, the electrical connection between the temperature measuring head and the ear thermometer body ensures that the signal transmission remains stable and reliable even after the temperature measuring head is adjusted at any angle.

[0018] The beneficial effects of this utility model are:

[0019] In use, this invention achieves stepless adjustment and adaptive locking of the temperature measuring head body relative to the ear thermometer body through the cooperation of the mounting base, mounting groove, spring brake ring and brake shaft. This effectively solves the problem of probe alignment caused by differences in the physiological structure of the ear canal and different measurement postures in the background technology, ensuring that the infrared probe is accurately aligned with the tympanic membrane, avoiding measurement errors caused by angular deviation touching the ear canal wall, significantly improving the accuracy and reliability of the measurement, and greatly improving the comfort of operation and the versatility of the equipment.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-4As shown, this relates to an adjustable ear thermometer, including an ear thermometer body 1, which serves as the core carrier of the device. Internally, it integrates a motherboard, battery, display screen, and signal processing unit, providing a platform for human-computer interaction and data processing, ensuring the integrity and functionality of the device. A mounting base 2 is fixedly connected to the top of the ear thermometer body 1, serving as the basic mounting platform for the entire adjustment mechanism. Mounting grooves 9 are formed on both inner walls of the mounting base 2. Spring brake rings are fixedly mounted on one inner wall of each of the two mounting grooves 9. Both spring brake rings rub against a brake shaft. A bearing seat 13 is fixedly connected to one end of each spring brake ring, and the inner ring of the bearing inside the bearing seat 13 is fixedly connected to the brake shaft. Each spring brake ring includes... A connecting seat 10 is fixedly connected to the mounting groove 9. A fixing ring 11 is fixedly connected to one side of the outer surface of the connecting seat 10, and the fixing ring 11 is fixedly connected to the seat body of the bearing seat 13. A spring body 12 is sleeved on the outer surface of the fixing ring 11, and the spring body 12 is fixedly connected to the connecting seat 10. A brake ring body 14 is fixedly connected to the other end of the spring body 12, and the brake ring body 14 is slidably sleeved on the outer surface of the seat body of the bearing seat 13. The spring body 12 provides a continuous and stable axial preload, which is the source of frictional damping and self-locking force. Its performance directly determines the adjustment feel and locking reliability. The outer ring of the bearing seat 13 and the inner ring of the brake ring body 14 are not circular, which has a guiding function to prevent the brake ring body 14 from deflecting.

[0029] Both brake shafts include a support shaft 5, and the support shaft 5 is fixedly connected to the inner ring of the bearing in the bearing housing 13. One end of the support shaft 5 is fixedly connected to a brake disc 8, and the brake disc 8 rubs against the brake ring body 14 and is fixedly connected to the movable seat 7. A stop block 6 is fixedly connected to one side of the support shaft 5.

[0030] Two deflection angle limiting blocks 15 are symmetrically fixedly connected to adjacent sides of the outer surface of the two bearing seats 13. The deflection angle limiting blocks 15 mechanically limit the maximum deflection angle of the temperature measuring head body 3 by contacting the stop block 6.

[0031] Two brake shafts are fixedly connected to a movable seat 7. The top of the movable seat 7 is fixedly connected to a temperature measuring head body 3. The temperature measuring head body 3 is electrically connected to the ear thermometer body 1.

[0032] The ear thermometer body 1 is equipped with a matching pen cap 4 on its upper part. The pen cap 4 matches the temperature measuring head body 3 and is fastened to the ear thermometer body 1.

[0033] Working principle: When the user needs to adjust the angle of the temperature measuring head body 3, a rotational force is applied to the movable seat 7 or the temperature measuring head body 3. This force is transmitted to the two brake shafts fixedly connected to the movable seat 7. The brake disc 8 and the brake ring body 14 sleeved on the bearing seat 13 are in frictional contact. When the applied torque is greater than the preload friction force applied by the spring body 12 to the brake ring body 14, the brake disc 8 will rotate relative to the brake ring body 14, thereby causing the entire temperature measuring head body 3 to deflect around the axis of the support shaft 5. The bearing built into the bearing seat 13 ensures the smooth rotation of the support shaft 5.

[0034] The spring brake ring is a key component for angle adjustment and locking. One end of the spring body 12 is fixed to the connecting seat 10, and the other end is connected to the brake ring body 14. The preload of the spring body 12 forces a large static friction force between the brake ring body 14 and the brake disc 8. When no external force is applied, this friction force is sufficient to overcome the weight of the temperature sensor body 3 itself and the torque caused by a slight external force, reliably locking the temperature sensor body 3 at any adjusted angle, effectively avoiding measurement errors caused by unexpected angle changes during measurement.

[0035] The deflection angle limiting block 15 is symmetrically fixed on the two bearing seats 13. When the movable seat 7 deflects to a certain angle, the stop block 6 will contact the deflection angle limiting block 15, thereby preventing it from rotating further. This design prevents the internal circuitry, such as the wires between the temperature measuring head body 3 and the ear thermometer body 1, from being damaged due to excessive rotation, ensuring the durability and safety of the product.

[0036] After adjusting the angle, the user holds the ear thermometer body 1 at the most comfortable and natural angle, and inserts the temperature measuring head body 3, which is already aligned with the ear canal, into the ear to measure the temperature. After use, the pen cap 4 can be fastened to the ear thermometer body 1 to cover the temperature measuring head body 3, providing protection against dust, dirt, and physical impact.
