Description

Technical Field

[0001] This utility model relates to the field of ear thermometer technology, specifically to an ear thermometer with a suspended probe. Background Technology

[0002] The ear thermometer consists of a gun body and a temperature probe. The temperature probe is cone-shaped and fixed to the gun body. The cone-shaped probe helps to penetrate deep into the ear canal and improve the accuracy of temperature measurement. When using it, insert the probe into the ear canal, make sure the probe fits well in the ear canal, press the measurement button, and the machine will display the temperature.

[0003] In some ear thermometers, the sensor is directly fixed to the plastic body, resulting in increasingly smaller probe tips. Smaller probes help measure a baby's temperature more accurately. However, because the probe is fixed to the body and has a small tip, at least two problems exist: 1. The small probe may cause discomfort or even pain to the baby if not operated properly. 2. Once the fixed probe is inserted into the ear canal, it is difficult to align with the eardrum if the person being tested is not cooperative, compromising measurement accuracy.

[0004] To overcome the above problems, existing ear thermometers have proposed solutions with movable probes. For example, the probe assembly is designed to be connected to a fixed plate via an elastic sleeve and spring. The spring is fitted onto an elastic limiting component (blade), and the fixed plate is then fixedly connected to the thermometer body. Alternatively, the probe and thermometer body can be connected via a guide rod with a spring on it, allowing the probe to move through the gap between the probe and the guide rod. While these movable designs allow the probe to move, they are still purely rigid structural connections. When the baby's head moves, it can still cause pain in the baby's ear canal after reaching a certain limit, resulting in poor comfort. Furthermore, the probe's position shifts after movement, reducing measurement accuracy.

[0005] In view of this, how to solve the problems of poor comfort and low measurement accuracy of existing ear thermometers with movable probes has become the research topic to be solved by this utility model. Utility Model Content

[0006] The purpose of this invention is to provide an ear thermometer with a suspended probe.

[0007] To achieve the above objectives, this utility model proposes a suspended probe ear thermometer, which includes a gun body and a temperature measuring probe. The front end of the gun body has a receiving cavity for accommodating the movable rear end of the temperature measuring probe. Its innovation lies in:

[0008] The gun body and the temperature probe are positioned and connected by a suspension assembly. The suspension assembly has a pressure plate, a fixing plate, and an elastic element located in the receiving cavity. The pressure plate is disposed on the gun body, the fixing plate is disposed on the temperature probe, and the elastic element includes a first elastic part and a second elastic part. The pressure plate and the fixing plate located at the rear are connected by the first elastic part, and the gun body and the fixing plate located at the front are connected by the second elastic part.

[0009] The ear thermometer is configured such that, in use, when the temperature probe is subjected to external pressing / squeezing force, one of the first elastic part and the second elastic part contracts and deforms, while the other stretches and deforms, so that the fixing plate and the temperature probe connected to the fixing plate are always in a suspended position.

[0010] The relevant contents of this utility model are explained as follows:

[0011] 1. In the above-mentioned technical solution of this utility model, a flexible connection between the gun body and the temperature probe is achieved by using a suspended assembly for positioning and connection. A pressure plate is mounted on the gun body, and a fixing plate is mounted on the temperature probe. The rear pressure plate and the fixing plate are connected by a first elastic part, and the front fixing plate and the gun body are connected by a second elastic part. The contraction and stretching deformation of both the first and second elastic parts under stress ensures that the push / pull force generated by the elastic elements acting on the fixing plate and the temperature probe keeps the temperature probe in a suspended state. The design angle between the gun bodies makes it easier to insert the smaller temperature probe into the ear canal during use. Once the temperature probe is in contact with the ear canal, it can be pushed further in until it reaches its full position. Because the temperature probe is suspended and has no rigid connection to the front or back of the gun body, the ear canal no longer bears greater force. This results in a better fit and greater comfort for the temperature probe, making it suitable for various ear canals. Even if the user moves their head slightly without cooperating, the temperature probe will remain in the measurement position, with the sensor aligned with the eardrum, without affecting the test results. Furthermore, the user will not experience any pain throughout the entire process, greatly improving the user experience.

[0012] 2. In the above technical solution, the first elastic part and the second elastic part of the elastic element can be integrally formed or separately formed. When integrally formed, one elastic element can be a single spring, with the middle part of the spring snapped onto the fixing plate, the spring forming the first elastic part at the rear end of the fixing plate, and the spring forming the second elastic part at the front end of the fixing plate; when separately formed, the first elastic element and the second elastic element can each be two springs, with the front end of the first elastic element and the rear end of the second elastic element respectively abutting against the fixing plate; the integral form has fewer parts, while the separate form is easier to assemble.

[0013] 3. In the above technical solution, the number of elastic elements in the suspension assembly is one or more. When the number of elastic elements in the suspension assembly is multiple, the multiple elastic elements are arranged in an array around the central axis of the temperature probe. Preferably, multiple elastic elements are used, which can ensure the stability of the temperature probe before and after testing. A single elastic element can also achieve the same function. The volume of a single elastic element can be increased to increase the contact area between the single elastic element and the pressure plate, the fixing plate, and the gun body, thereby maintaining stability.

[0014] 4. In the above technical solution, one or more buckles are provided on the front end face and the rear end face of the fixing plate, and the buckles limit the elastic element. Using buckles to limit and fix the first elastic part and the second elastic part that cooperate with the fixing plate is simple to assemble and better forms a suspended state with the fixing plate as a floating fulcrum.

[0015] 5. In the above technical solution, the front and rear faces of the fixing plate are each provided with three or more buckles, and the included angle α formed between each buckle and the adjacent buckle is the same. This multi-buckle design is used in conjunction with multiple elastic elements to keep the angle between the temperature probe and the gun body at the design value when the ear thermometer is in the initial state. When there are three buckles, the included angle α formed between each buckle and the adjacent buckle is 60°, that is, ∠a=60°.

[0016] 6. In the above technical solution, the buckle includes elastic arms and locking heads. Multiple elastic arms are connected to the end face of the fixed plate, and locking heads are provided on the elastic arms. The locking heads are combined to form a buckle with an outer diameter of D. The elastic element is a spring, and the inner diameter of the spring is d, where D > d. With this buckle structure design, when the elastic element is assembled onto the buckle, the elastic arm first contracts and deforms, causing the locking head to converge. After passing through the spring, the elastic arm and locking head return to their original positions, and the locking head locks the spring, preventing the spring from falling off.

[0017] 7. In the above technical solution, the outer edge of the clamp head is chamfered, where Dd ≥ 0.5mm. The chamfer on the clamp head will facilitate the guiding effect of the spring during assembly, improve assembly efficiency and assembly treatment. Designing the diameter D of the buckle to be 0.5mm larger than the inner diameter d of the spring can better hold the spring in place, further preventing the spring from falling off the buckle during use and improving product stability.

[0018] 8. In the above technical solution, the pressure block is provided with a first limiting post for limiting the first elastic part, the first limiting post extending towards the front end; the distance between the front-facing top surface of the first limiting post and the snap-on top surface of the rear-facing side of the fixing plate is B; an ear sleeve is detachably mounted on the temperature probe, the temperature probe has a snap-on part facing the rear end for snapping the ear sleeve, the distance between the rear-facing top surface of the snap-on part and the front-facing side of the gun body is b; in the initial state, the ear thermometer is configured such that bB≥1.5mm. The first limiting post effectively limits the first elastic part. The number and position of the first limiting post correspond to the buckle. The first limiting post mainly prevents the spring of the first elastic part from loosening and limits its extension and retraction. The dimensional relationship between the distance B between the front top surface of the first limiting post and the buckle top surface of the rear end face of the fixing plate, and the distance b between the rear top surface of the snap-fit ​​part and the front front face of the gun body, can prevent the ear cover from not being in place or falling out when assembling the ear cover or during actual measurement, thus increasing practicality.

[0019] 9. In the above technical solution, the gun body is provided with a second limiting post for limiting the second elastic part. The second limiting post extends towards the rear end. In the initial state, the first limiting post, the buckle, the second limiting post, and the elastic element are coaxial. The front end of the first limiting post and the rear end of the second limiting post are provided with bevels. The second limiting post effectively limits the second elastic part. The number and position of the second limiting post correspond to the buckle. The second limiting post mainly serves to prevent the spring of the second elastic part from loosening and to limit its extension and retraction. The bevels at the front end of the first limiting post and the rear end of the second limiting post make the assembly of the elastic element (spring) more convenient and precise.

[0020] 10. In the above technical solution, the temperature probe further includes a temperature sensor, a probe plastic part, and a soft adhesive. The temperature sensor is located at the front end of the probe plastic part, and the soft adhesive surrounds the periphery of the probe plastic part. When the temperature probe is inserted into the user's ear canal, the soft adhesive part directly contacts the ear canal, and the soft adhesive bears part of the pressing / squeezing force during slight shaking by the user, thereby improving measurement comfort.

[0021] 11. In the above technical solution, the rear end of the first elastic part is connected to the front end face of the pressure plate, the front end of the first elastic part is connected to the rear end face of the fixing plate, the front end of the second elastic part is connected to the rear end face of the fixing plate, and the front end of the second elastic part is connected to the rear end face of the gun body.

[0022] 12. In the above technical solution, the definition of "forward" in terms such as "front end" and "front end" refers to the direction in which the temperature measuring probe of the ear thermometer is aligned with the inside of the ear canal and points towards the tympanic membrane, while the "back" in terms such as "back end" and "rear end" refers to the direction opposite to that of pointing towards the tympanic membrane.

[0023] 13. In this utility model, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0024] 14. In this utility model, the terms "center", "upper", "lower", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional assembly relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. If the manual pressure relief valve is inverted or placed horizontally, the corresponding orientation is also adjusted accordingly.

[0025] 15. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] Due to the application of the above solution, this utility model has the following advantages and effects compared with the prior art:

[0027] This utility model innovatively designs a suspended probe ear thermometer with a novel structure. In this ear thermometer, the body and the temperature probe are positioned and connected using a suspended assembly, achieving a soft connection between them. The contraction and stretching deformation of the first and second elastic parts under stress allows the push / pull force generated by the elastic elements acting on the fixed plate and the temperature probe to keep the temperature probe suspended and maintain a designed angle with the body. During use, the smaller temperature probe is easier to insert into the ear canal. Once the probe is in contact with the ear canal, it can be pushed further in until it reaches its full position. Because the temperature probe is suspended and has no rigid connection to the body, the ear canal is no longer subjected to greater force. This results in better fit and comfort, suitable for various ear canals. Even with slight head movements without user cooperation, the temperature probe remains in the measuring position, with the sensor aligned with the tympanic membrane, without affecting the test results. Furthermore, the user will not experience pain throughout the process, significantly improving the user experience. Attached Figure Description

[0045] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0046] Example 1, as Figures 1 to 10 As shown in the figure, this utility model embodiment proposes a suspended probe ear thermometer. The ear thermometer includes a gun body 1 and a temperature measuring probe 2. The front end of the gun body 1 has a receiving cavity 10 for accommodating the rear end of the temperature measuring probe 2. The gun body 1 and the temperature measuring probe 2 are positioned and connected by a suspended assembly 3. The suspended assembly 3 has a pressure plate 31, a fixing plate 32, and an elastic element 33 located in the receiving cavity 10. The pressure plate 31 is disposed on the gun body 1, the fixing plate 32 is disposed on the temperature measuring probe 2, and the elastic element 33 includes a first elastic part 331 and a second elastic part 332. The pressure plate 31 and the fixing plate 32 located at the rear end are connected by the first elastic part 331, and the gun body 1 located at the front end and the fixing plate 32 are connected by the second elastic part 332.

[0047] The suspended probe ear thermometer of this utility model embodiment has an initial state and a usage state.

[0048] In the initial state: as follows Figure 8As shown, the force generated by the elastic deformation recovery ability of the first elastic part 331 located in the rear section and the second elastic part 332 located in the front section makes the fixing plate 32 and the temperature probe 2 connected to the fixing plate 32 suspended in the air, and the temperature probe 2 and the gun body 1 maintain the designed angle.

[0049] In use, such as Figure 9 , Figure 10 As shown, when the temperature probe 2 is subjected to external pressing / compression force, one of the first elastic part 331 and the second elastic part 332 contracts and deforms, while the other stretches and deforms, so that the fixing plate 32 and the temperature probe 2 connected to the fixing plate 32 are always in a suspended position, and there is no rigid connection between the front and the back of the temperature probe 2.

[0050] After adopting the above-described embodiments of this utility model, a soft connection between the gun body 1 and the temperature probe 2 is achieved by using a suspended assembly 3 for positioning and connection. The pressure plate 31 is mounted on the gun body 1, and the fixing plate 32 is mounted on the temperature probe 2. The rear pressure plate 31 and the fixing plate 32 are connected by a first elastic part 331, and the front fixing plate 32 and the gun body 1 are connected by a second elastic part 332. The first elastic part 331 and the second elastic part 332, under stress, provide a flexible connection. The contraction and stretching deformations allow the elastic element 33, which undergoes elastic deformation on the fixed plate 32 and the temperature probe 2, to generate a pushing / pulling force that keeps the temperature probe 2 suspended. Since the temperature probe 2 is suspended and has no rigid connection to the front or back of the gun body 1, the ear canal no longer bears greater force. The temperature probe 2 fits the ear canal better and is more comfortable, making it suitable for various ear canals. Even when the user does not cooperate with slight head movements, the temperature probe 2 will still be in the measuring position, with the sensor aligned with the tympanic membrane, without affecting the test results.

[0051] In one embodiment of this utility model, the first elastic part 331 and the second elastic part 332 in the elastic member 33 are integrally formed. When integrally formed, one elastic member 33 can be a whole spring, wherein the middle part of the spring is snapped onto the fixing plate 32, the spring forms the first elastic part 331 at the rear end of the fixing plate 32, and the spring forms the second elastic part 332 at the front end of the fixing plate 32. The number of integrally formed parts is small.

[0052] In another embodiment of this utility model, such as Figure 2 , Figure 3As shown, the first elastic part 331 and the second elastic part 332 in the elastic member 33 are set separately. When set separately, the first elastic member 33 and the second elastic member 33 can be two springs respectively. The front end of the first elastic member 33 and the rear end of the second elastic member 33 are close to the fixing plate 32 respectively. The separate setting is more convenient for assembly.

[0053] In another embodiment of this utility model, such as Figure 2 As shown, the number of elastic elements 33 in the suspension assembly 3 is multiple. When the number of elastic elements 33 in the suspension assembly 3 is multiple, the multiple elastic elements 33 are arranged in an array around the central axis of the temperature probe 2. Preferably, there are multiple elastic elements 33, which can ensure the stability of the temperature probe 2 before and after the test.

[0054] In one embodiment of this utility model, the number of elastic elements 33 in the air suspension component 3 is one. One elastic element 33 can also achieve a certain stability. The volume of a single elastic element 33 can be increased to increase the contact area between the single elastic element 33 and the pressure plate 31, the fixing plate 32 and the gun body 1, thereby maintaining stability.

[0055] In another embodiment of this utility model, such as Figure 4 , Figure 5 As shown, one or more latches 4 are provided on the front and rear faces of the fixing plate 32, which limit the elastic element 33. Using latches 4 to limit and fix the first elastic part 331 and the second elastic part 332 that cooperate with the fixing plate 32 simplifies assembly and better achieves a suspended state with the fixing plate 32 as a floating fulcrum.

[0056] In another embodiment of this utility model, such as Figure 4 , Figure 5 As shown, the fixing plate 32 has three or more buckles 4 on its front and rear faces, and the included angle α formed between each buckle 4 and its adjacent buckle 4 is the same. This design of multiple buckles 4 is used in conjunction with multiple elastic elements 33 to keep the angle between the temperature probe 2 and the gun body 1 at the design value when the ear thermometer is in the initial state. When there are three buckles 4, the included angle α formed between each buckle 4 and its adjacent buckle 4 is 60°, that is, ∠a=60°.

[0057] In the above embodiments, the present invention is not limited thereto. The number of buckles 4 can also be set to 4, 5, 6, etc. Setting multiple buckles 4 to match the corresponding number of elasticity can make the temperature probe 2 more stable.

[0058] In one embodiment of this utility model, such as Figure 4As shown, the buckle 4 includes elastic arms 41 and locking heads 42. Multiple elastic arms 41 are connected to the end face of the fixing plate 32. The locking heads 42 are provided on the elastic arms 41. After the locking heads 42 are combined, a buckle 4 with an outer diameter of D is formed. The elastic element 33 is a spring with an inner diameter of d, where D > d. With this structural design of the buckle 4, when the elastic element 33 is assembled onto the buckle 4, the elastic arms 41 first contract and deform, causing the locking heads 42 to partially converge and pass through the spring. After that, the elastic arms 41 and locking heads 42 return to their original positions, and the locking heads 42 lock the spring, preventing the spring from falling off.

[0059] In another embodiment of this utility model, such as Figure 4 As shown, the outer edge of the clip 42 is chamfered, where Dd ≥ 0.5mm. The chamfer on the clip 42 will facilitate the guiding effect of the spring during assembly, improve assembly efficiency and treatment. The diameter D of the buckle 4 is designed to be 0.5mm larger than the inner diameter d of the spring, which can better hold the spring in place and further prevent the spring from falling off the buckle 4 during use, thus improving product stability.

[0060] In the above embodiments, the present invention is not limited thereto. The diameter D of the buckle 4 can be designed to be greater than the inner diameter d of the spring by a value of 0.5mm, 0.6mm, 0.7mm, etc. If the number of buckles 4 and corresponding springs is large, smaller buckles 4 and smaller springs can be used. In this case, the value can be 0.4mm, 0.3mm, etc.

[0061] In another embodiment of this utility model, such as Figure 6 , Figure 7As shown, the pressure block is provided with a first limiting post 5 for limiting the first elastic part 331, and the first limiting post 5 extends toward the front end; the distance between the front-facing top surface of the first limiting post 5 and the top surface of the buckle 4 on the rear-facing side of the fixing plate 32 is B; an ear cover is detachably mounted on the temperature probe 2, and the temperature probe 2 has a locking part 20 facing the rear end for locking the ear cover, and the distance between the rear-facing top surface of the locking part 20 and the front-facing side of the gun body 1 is b; in the initial state, the ear thermometer is configured such that bB≥1.5mm. The first limiting post 5 effectively limits the first elastic part 331. The number and position of the first limiting post 5 correspond to the buckle 4. The first limiting post 5 mainly serves to prevent the spring of the first elastic part 331 from loosening and to limit its extension and retraction. The dimensional relationship between the distance B between the front top surface of the first limiting post 5 and the top surface of the buckle 4 on the rear end face of the fixing plate 32, and the distance b between the rear top surface of the snap-fit ​​part 20 and the front end face of the gun body 1, can prevent the ear cover from failing to be in place or falling out during assembly or actual measurement, thus increasing practicality. The dimensional relationship setting of bB ≥ 1.5mm can be set to 1.5mm, 1.6mm, 1.7mm, etc.

[0062] In one embodiment of this utility model, such as Figure 3 As shown, the gun body 1 is provided with a second limiting post 6 for limiting the second elastic part 332. The second limiting post 6 extends towards the rear end. In the initial state, the first limiting post 5, the latch 4, the second limiting post 6, and the elastic element 33 are coaxial. The front end of the first limiting post 5 and the rear end of the second limiting post 6 are provided with an angle. The second limiting post 6 effectively limits the second elastic part 332. The number and position of the second limiting post 6 correspond to those of the latch 4. The second limiting post 6 mainly serves to prevent the spring of the second elastic part 332 from loosening and to limit its extension and retraction. The angle provided at the front end of the first limiting post 5 and the rear end of the second limiting post 6 makes the assembly of the elastic element 33 (spring) more convenient and precise.

[0063] In another embodiment of this utility model, such as Figure 2 As shown, the temperature probe 2 also includes a temperature sensor 23, a probe plastic part 21, and a soft adhesive 22. The temperature sensor 23 is located at the front end of the probe plastic part 21, and the soft adhesive 22 surrounds and wraps around the periphery of the probe plastic part 21. When the temperature probe 2 is inserted into the user's ear canal, the soft adhesive 22 makes direct contact with the ear canal, and during slight shaking by the user, the soft adhesive 22 bears part of the pressing / squeezing force, thereby improving measurement comfort.

[0064] Through the implementation of the above embodiments, some novel suspended probe ear thermometers are proposed, which can solve the problems of poor comfort and low measurement accuracy of existing ear thermometers with movable probes. The suspended temperature probe 2 is not rigidly connected to the front and rear of the gun body 1, so the ear canal no longer bears greater force. The temperature probe 2 fits the ear canal better and is more comfortable, suitable for various ear canals. When the user moves their head slightly without cooperation, the temperature probe 2 will still be in the measurement position, with the sensor aligned with the tympanic membrane, without affecting the test results, thus achieving the purpose of this utility model.

[0065] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
