Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Referring to fig. 1, 2 and 3, in an embodiment of the present application, a temperature measuring device 1 is provided, which is characterized by including a temperature measuring probe 2, a flexible wrap 3, a plurality of temperature sensitive units 4 and a plurality of heat conductors 5, wherein each temperature sensitive unit 4 is disposed on the temperature measuring probe 2, and the temperature sensitive units 4 are separated from each other;

the flexible wrapping 3 wraps the heat conductor 5 on the temperature measuring probe 2, so that the heat conductor 5 is pressed to be in close contact with the temperature sensitive unit 4, and a single heat conductor 5 corresponds to a single temperature sensitive unit 4;

the flexible wrapping object 3 is provided with a temperature measuring port, and a temperature measuring end of the heat conductor 5 penetrates through the temperature measuring port and is exposed outside the flexible wrapping object 3, wherein the temperature measuring end of the heat conductor 5 is the tail end of the heat conductor 5, which is far away from the temperature sensitive unit 4.

Preferably, the flexible wrap 3 is made of a heat insulating material.

Preferably, the temperature sensitive units 4 are spaced at the same interval.

In this embodiment, the temperature measuring device 1 includes a temperature measuring probe 2, a flexible wrap 3, a plurality of temperature sensitive units 4 and a plurality of heat conductors 5, wherein the temperature sensitive units 4 may specifically be temperature sensors for sensing temperature. Wherein, the temperature measuring probe 2 can be directly arranged on the main body of the temperature measuring device 1 (as shown in figure 3); or the temperature measuring probe 2 and the main body of the temperature measuring device 1 are separated from each other, and the temperature measuring probe 2 and the main body of the temperature measuring device 1 (the main body comprises a processor, a display screen and other components) are connected through a wireless signal or signal transmission line, so that the transmission of temperature measuring data is realized. The temperature sensitive units 4 are all arranged on the temperature measuring probe 2, the temperature sensitive units 4 are separated from each other, are not in contact with each other and are far away from each other as far as possible, and thermal isolation among the temperature sensitive units 4 is achieved. Preferably, the intervals between the temperature sensitive units 4 are the same, so that even if the temperature sensitive units 4 are uniformly distributed on the temperature measuring probe 2, the temperature sensitive units 4 on the temperature measuring probe 2 can be uniformly distributed in a temperature measuring area during temperature measurement, and the heat loss conditions of the temperature sensitive units 4 are the same; meanwhile, the temperature sensitive units 4 have the same distribution layout at intervals, so that the temperature sensitive units 4 have the same thermal impedance, the temperature sensitive units 4 are ensured to have the same temperature measuring environmental conditions, and the accuracy of the temperature data sensed by the temperature sensitive units 4 is effectively improved. The temperature measuring device 1 further comprises a processor, the processor respectively receives the temperature data sensed by the temperature sensitive units 4, and whether the temperature measuring probe 2 is normally used or not is judged according to the temperature data change curves corresponding to the temperature sensitive units 4. For example, if the deviation degrees between the temperature data change curves of the respective groups are within the preset deviation range and the difference between the final values of the temperature data of the respective groups is within the preset difference range, it can be determined that the temperature probe 2 is normally deployed and does not fall off. And after the processor judges that the temperature measuring probe 2 is normally deployed, averaging the final values of all the temperature data or taking the maximum value as a final temperature measuring result to output.

The heat conductor 5 has excellent heat conduction performance, and the single heat conductor 5 is correspondingly arranged on the top of the single temperature sensitive unit 4. Each heat conductor 5 is wrapped on the temperature measuring probe 2 by the flexible wrapping object 3, the heat conductor 5 is pressed to be in close contact with the temperature sensitive unit 4 through the binding force between the flexible wrapping object 3 and the temperature measuring probe 2, the flexible connection between the heat conductor 5 and the temperature sensitive unit 4 is realized, and the temperature of an object contacted by the heat conductor 5 can be transmitted to the temperature sensitive unit 4 through the heat conductor 5. A temperature measuring port is formed in the flexible wrapping 3, and a temperature measuring end of the heat conductor 5 penetrates through the temperature measuring port and is exposed outside the flexible wrapping 3, so that the heat conductor 5 is fixed on the flexible wrapping 3; the temperature measuring end of the heat conductor 5 is the tail end of the heat conductor 5 far away from the temperature sensitive unit 4. Preferably, the heat conductor 5 is disposed with a fixing member 6, and the fixing member 6 may be a sheet, a cylinder or a ring; the fixing member 6 is used for hanging the flexible wrap 3, so that the flexible wrap 3 can press the heat conductor 5 to be in close contact with the temperature sensitive unit 4 through the fixing member 6. When the temperature measuring device 1 is used for measuring temperature (for example, when body temperature is measured, a user needs to clamp the temperature measuring probe 2 in an armpit and other temperature measuring areas), the temperature measuring end of the heat conductor 5 protrudes out of the flexible wrapping object 3, and can preferentially contact the temperature measuring areas (for example, skin tissues of a human body), so that the temperature of the temperature measuring areas is conducted to the temperature sensitive unit 4 through the heat conductor 5, and the temperature sensitive unit 4 can sense the temperature of the temperature measuring areas through the heat conductor 5. Meanwhile, the temperature sensitive units 4 are separated from each other, and the heat conductor 5 is in direct contact with the temperature measuring area, so that thermal isolation among the temperature sensitive units 4 can be ensured, and the problem that the accuracy of temperature sensing is influenced by thermal connection among the temperature sensitive units 4 is avoided (if the heat conductor 5 does not break through the flexible wrapping object 3, the heat conductor 5 is in direct contact with the flexible wrapping object 3, and each temperature sensitive unit 4 is equivalent to have thermal connection through the flexible wrapping object 3, so that the accuracy of temperature sensing of the multiple temperature sensitive units 4 can be influenced). Preferably, the flexible covering 3 is made of a heat insulating material, so that the thermal insulation between the heat conductors 5 covered by the flexible covering 3 is further improved, and the measurement accuracy of the temperature measuring device 1 with the multiple temperature sensitive units 4 is further improved.

When the temperature measuring probe 2 is impacted by the outside (for example, the impact force when the temperature measuring probe 2 falls), the temperature sensitive unit 4 is connected with the heat conductor 5 by the flexible wrapping 3 to press and restrict the heat conductor 5, and the temperature sensitive unit 4 is not rigidly connected with the heat conductor 5. The flexible connection between the heat conductor 5 and the temperature sensitive unit 4 can be disconnected due to impact deflection of the heat conductor 5, so that the heat conductor 5 cannot conduct impact force to the temperature sensitive unit 4, the temperature sensitive unit 4 fixed on the circuit board 8 in the probe cannot be subjected to peeling impact, and the impact resistance of the temperature sensitive unit 4 and the probe is effectively improved.

Further, the heat conductor 5 is in a truncated cone shape, the cross-sectional area of the connecting end of the heat conductor 5 is larger than that of the temperature measuring end of the heat conductor 5, and the connecting end of the heat conductor 5 is the tail end of the heat conductor 5 directly contacting with the temperature sensitive unit 4;

the area of the temperature measuring port is smaller than the cross-sectional area of the connecting end of the heat conductor 5.

In this embodiment, the heat conductor 5 is in the shape of a truncated cone, and the end of the heat conductor 5 in direct contact with the temperature sensitive unit 4 is defined as the connection end of the heat conductor 5; the cross-sectional area of the connecting end of the heat conductor 5 is larger than that of the temperature measuring end of the heat conductor 5, namely, the end with larger area of the truncated cone-shaped heat conductor 5 is flexibly connected with the temperature sensitive unit 4, and the end with smaller area is contacted with the temperature measuring area. The area of the temperature measuring port of the flexible wrapping object 3 is smaller than the cross-sectional area of the connecting end of the heat conductor 5, when the heat conductor 5 penetrates through the temperature measuring port of the flexible wrapping object 3, the part, with the cross-sectional area larger than the area of the temperature measuring port, of the heat conductor 5 can be wrapped and bound by the flexible wrapping object 3, and therefore the heat conductor 5 can be pressed and fixed on the temperature measuring probe 2 through the flexible wrapping object 3.

Further, the heat conductor 5 is cylindrical, at least two first fixing pieces are arranged on a single heat conductor 5, the first fixing pieces are flaky or cylindrical, and the first fixing pieces are located on the heat conductor 5 at the same height and are distributed at equal intervals;

the flexible wrapping 3 wraps the first fixing piece and the temperature measuring probe 2 to press the heat conductor 5 to be in close contact with the temperature sensitive unit 4.

Preferably, the side edge of one end of the first fixing piece, which is far away from the heat conductor 5, is rounded.

In this embodiment, the heat conductor 5 may also be cylindrical, and at least two first fixing members, which are sheet-shaped or cylindrical, are disposed on a single heat conductor 5. The first fixing members are arranged at the same height above the heat conductor 5 and are equidistantly distributed. When the heat conductor 5 and the temperature probe 2 are wrapped by the flexible wrapping object 3, the heat conductor 5 above the first fixing part can penetrate through the temperature measuring port and be exposed outside the flexible wrapping object 3, the flexible wrapping object 3 is hung on the first fixing part, the first fixing part and the temperature probe 2 are bound, and therefore the heat conductor 5 and the temperature sensitive unit 4 are pressed to be in close contact through the first fixing part. Moreover, since the first fixing members are located on the heat conductor 5 and distributed at the same height and the same distance, the pressing force of the flexible wrapping object 3 on the heat conductor 5 can be distributed in a balanced manner (the flexible wrapping object 3 restrains the pressing force between the heat conductor 5 and the temperature sensitive unit 4 to act on the first fixing members, and the first fixing members distributed at the same height and the same distance can ensure that the pressing force is not deviated to a certain direction but distributed in a balanced manner), so that the stability of connection between the heat conductor 5 and the temperature sensitive unit 4 is ensured. Preferably, the fillet is all done to the one end side that heat conductor 5 was kept away from to first mounting, and each side of first mounting and the 3 contact one ends of flexible parcel all is provided with the fillet promptly to avoid being too sharp because of the side, lead to flexible parcel 3 to be cut apart by the side of first mounting.

Further, the heat conductor 5 is cylindrical, a second fixing piece is arranged on a single heat conductor 5, the second fixing piece is annular, and the second fixing piece is parallel to the radial section of the heat conductor 5;

the flexible wrapping 3 wraps the second fixing piece and the temperature measuring probe 2 to press the heat conductor 5 to be in close contact with the temperature sensitive unit 4.

In this embodiment, the heat conductor 5 is cylindrical, and the second fixing member is provided on the heat conductor 5, and the second fixing member is annular as a whole, and the annular second fixing member is provided parallel to the radial cross section of the heat conductor 5. When the heat conductor 5 and the temperature probe 2 are wrapped by the flexible wrapping object 3, the heat conductor 5 above the second fixing part can penetrate through the temperature measuring port and be exposed outside the flexible wrapping object 3, the flexible wrapping object 3 is hung on the second fixing part, the second fixing part and the temperature probe 2 are bound, and therefore the heat conductor 5 is pressed to be in close contact with the temperature sensitive unit 4 through the second fixing part. Because the second fixing piece is annular and is integrally parallel to the radial section of the heat conductor 5 during deployment, the pressing force of the flexible wrapping object 3 acting on the second fixing piece can be uniformly distributed, and the connection stability between the heat conductor 5 and the temperature sensitive unit 4 is effectively ensured. Preferably, each side of second mounting and the flexible wrapper 3 one end of contact all is provided with the fillet to avoid because of the side is too sharp, lead to flexible wrapper 3 to be split by the side of second mounting.

Furthermore, a temperature measuring bulge 7 is arranged at the temperature measuring end of the heat conductor 5.

Preferably, the temperature measuring bulge 7 is hemispherical, and the maximum cross-sectional area of the temperature measuring bulge 7 is the same as the cross-sectional area of the temperature measuring end of the heat conductor 5.

In this embodiment, the protruding setting of temperature measurement 7 is on the temperature measurement end surface of heat conductor 5, and when the user used temperature probe 2 to carry out temperature measurement, temperature measurement protruding 7 can be inseparabler with the regional surface of temperature measurement (for example human skin tissue) contact more, can better improve the installation steadiness between temperature probe 2 and the temperature measurement region, also can improve temperature measurement's the degree of accuracy. Preferably, the temperature measuring bulge 7 is hemispherical as a whole, and the maximum cross-sectional area of the temperature measuring bulge 7 is the same as that of the temperature measuring end of the heat conductor 5. When the temperature measuring device 1 is used for measuring the body temperature (the temperature measuring probe 2 is clamped in the armpit and other areas), the contact surface of the hemispherical temperature measuring bulge 7 and the skin tissue of the human body is a hemispherical surface, so that the comfort level of a user can be improved (the smooth contact surface has smaller irritation and obtrusiveness to the skin tissue of the human body compared with the contact surface with edges and corners, and therefore, the smooth contact surface has higher comfort level).

Furthermore, the temperature measuring probe 2 comprises a circuit board 8, the circuit board 8 is arranged inside the temperature measuring probe 2, the temperature sensitive unit 4 is fixedly arranged on the circuit board 8, and the circuit board 8 is a fracture circuit board or a ceramic substrate circuit board;

the split circuit board comprises a plurality of sub circuit boards, the sub circuit boards are mutually separated, and the single temperature sensitive unit 4 is correspondingly arranged on the single sub circuit board.

In this embodiment, the temperature probe 2 includes a circuit board 8, the circuit board 8 is disposed inside the temperature probe 2, and the temperature sensitive unit 4 is fixedly welded on the circuit board 8. The circuit board 8 is preferably a fracture circuit board or a ceramic substrate circuit board 8, and the substrate of the ceramic substrate circuit board 8 is a ceramic material, so that the temperature-sensitive units 4 arranged on the ceramic circuit board 8 can have the same thermal impedance and thermal loss. The split circuit board comprises a plurality of sub circuit boards which are separated from each other, and the single temperature sensitive unit 4 is correspondingly arranged on the single sub circuit board. Similarly, the sub-circuit boards separated from each other can ensure that the temperature sensitive units 4 arranged on the sub-circuit boards are separated from each other, have the same thermal impedance and heat loss, and improve the temperature measurement accuracy.

The temperature measuring device provided by the embodiment comprises a temperature measuring probe 2, a flexible wrapping object 3, a plurality of temperature sensitive units 4 and a plurality of heat conductors 5, wherein the temperature sensitive units 4 are arranged on the temperature measuring probe 2, and the temperature sensitive units 4 are mutually separated. The flexible wrapping 3 wraps the heat conductor 5 on the temperature measuring probe 2, so that the heat conductor 5 is pressed to be in close contact with the temperature sensitive unit 4, and the single heat conductor 5 corresponds to the single temperature sensitive unit 4. The flexible wrapping 3 is provided with a temperature measuring port, and the temperature measuring end of the heat conductor 5 passes through the temperature measuring port and is exposed outside the flexible wrapping 3, wherein the temperature measuring end of the heat conductor 5 is the tail end of the heat conductor 5, which is far away from the temperature sensitive unit 4. Because the connection between the temperature sensitive unit 4 and the heat conductor 5 is realized by the compression and the restraint of the flexible wrappage 3 to the heat conductor 5, the temperature sensitive unit 4 and the heat conductor 5 are not rigidly connected. When the probe is impacted, the flexible connection between the heat conductor 5 and the temperature sensitive unit 4 is broken due to impact deflection of the heat conductor 5, so that the heat conductor 5 cannot conduct impact force to the temperature sensitive unit 4, the temperature sensitive unit 4 fixed on the circuit board 8 in the probe cannot be impacted in a stripping manner, and the impact resistance of the temperature sensitive unit 4 and the probe is effectively improved.
