The invention is capable of other and different embodiments and its several details are capable of modifications and various changes in detail, all without departing from the spirit and scope of the present invention. The drawings of the present invention are for illustrative purposes only and are not intended to be drawn to scale. The following embodiments will further explain the related art of the present invention in detail, but the disclosure is not intended to limit the scope of the present invention. In addition, it should be understood that although the terms "first," "second," "third," etc. may be used herein to describe various components, these components should not be limited by these terms. These terms are used primarily to distinguish one element from another. In addition, the term "or" as used herein should be taken to include any one or combination of more of the associated listed items as the case may be.
Fig. 1 to 3 are schematic diagrams illustrating steps of a temperature calibration method of an ear thermometer with a probe cover according to the present invention in fig. 1, fig. 2 is a schematic diagram illustrating a perspective view of the ear thermometer and the probe cover according to the present invention, and fig. 3 is a schematic diagram illustrating a front view of the ear thermometer according to the present invention. The invention provides an ear thermometer T and a probe sleeve U which are matched with each other in structure. The ear thermometer T includes an ear thermometer body T1, a probe T2, and a plurality of sensing assemblies T3. The probe T2 is arranged on the ear thermometer body T1, and the probe T2 can be provided with a probe sleeve U sleeved on the probe sleeve T1. A plurality of sensing assemblies T3 are disposed on the ear thermometer body T1 and adjacent to the probe T2. In addition, the ear thermometer T further includes a control assembly (not shown). The control component is disposed inside the ear thermometer body 1, the control component is electrically connected to each sensing component T3, and the control component includes a memory unit (not shown).
The probe cover U includes a conical body U1, an annular elastomer U2, and a flange U3. The conical body U1 has a closed end U11 and an open end U12, the closed end U11 being opposite the open end U12. It should be noted that the infrared ray referred to herein is mainly an infrared ray emitted from a human body. Closed end U11 itself has a thickness. Since the closed end U11 is the place for infrared rays to pass through, i.e. the main passing place of infrared rays, the closed end U11 has different infrared ray transmittance according to the change of its thickness. For the probe cover U, the infrared ray transmittance of the probe cover U is actually the infrared ray transmittance of the closed end U11. Thus, the probe cover U will have a different infrared transmission rate depending on the change in thickness of the closed end U11. An annular elastomer U2 is attached to the open end U12 of the conical body U1. The flange U3 is connected to an annular elastomer U2, and an annular elastomer U2 is located between the conical body U1 and the flange U3. It should be noted that the probe cover U provided by the embodiment of the present invention may be an integrally formed hard earcap.
The invention provides a temperature correction method of an ear thermometer T with a probe sleeve U, which comprises the following steps:
step S101: an ear thermometer T with a probe cover U is provided, the ear thermometer T comprises a plurality of sensing elements T3 and a control element with a memory unit, the plurality of sensing elements T3 are used for sensing the infrared ray penetration rate of the probe cover U to obtain a measured penetration rate value, and the memory unit stores a preset penetration rate value corresponding to the infrared ray penetration rate of the probe cover U.
In detail, in step S101, each sensing element T3 includes an on state and an off state, so that the plurality of sensing elements T3 are arranged and combined to form a plurality of different sensing combinations, the plurality of different sensing combinations respectively correspond to a plurality of different infrared transmittances, and two infrared transmittances corresponding to any two sensing combinations of the plurality of different sensing combinations are different from each other. Similarly, the flange U3 has a plurality of detecting positions U30, each detecting position U30 has a positive detecting pattern or a negative detecting pattern, so that the detecting positions U30 are arranged and combined to form a plurality of different detecting combinations, the detecting combinations respectively correspond to a plurality of different infrared transmittances, and two infrared transmittances corresponding to any two detecting combinations in the detecting combinations are different from each other.
Further, in the embodiment of the present invention, the sensing element T3 of the ear thermometer T is a mechanical latch, the open state of the sensing element T3 is a latch pressed state, and the closed state of the sensing element T3 is a latch not pressed state. The positive detection mode is that the flange U3 is formed with an opening at the detection position U30, and the negative detection mode is that the flange U3 is not formed with an opening at the detection position U30. However, the present invention is not limited thereto. In other embodiments, a positive detection pattern may indicate that the flange U3 is formed of a transparent material at the detection position U30, and a negative detection pattern may indicate that the flange is formed of an opaque material at the detection position U30 (not shown). The sensing element T3 may be, for example, a photoelectric switch (photo sensor), which uses the light transmittance/opacity of the detecting positions U30 on the flange U3 of the probe cover U to block or transmit the light beam emitted by the photoelectric switch, thereby detecting the infrared transmittance of the probe cover U. The on state of the sensing element T3 is the state in which the light beam emitted by the photoelectric switch is blocked, and the off state of the sensing element T3 is the state in which the light beam emitted by the photoelectric switch is not blocked.
When the probe cover U is fitted over the probe T2 of the ear thermometer T, if each sensing element T3 is in an open state (i.e., a pin is pressed down), it indicates that the detecting position U30 on the flange U3 of the probe cover U corresponding to the sensing element T3 is in a negative detecting state (no hole is formed). Conversely, if each sensor unit T3 is in the closed state (i.e., the latch is not pressed), it indicates that the detecting position U30 on the flange U3 of the probe cover U corresponding to the sensor unit T3 is in the positive detecting state (forming the hole). When each sensing element T3 is in the ON state (i.e., the pin is pressed down), each sensing element T3 sends a sensing signal to the control element. Therefore, the sensing elements T3 form different sensing combinations (e.g., one sensing element T3 is turned on and the other sensing element T3 is turned off) whereby no sensing signal or at least one sensing signal is sent to the control element. The control component can identify the infrared penetration rate of the probe cover U according to the received sensing signal (or not receiving the sensing signal), and then obtain the measured penetration rate value.
The memory unit in the control component stores a preset infrared penetration value and a correction parameter. The control component corrects the sensed initial temperature according to a preset infrared penetration value and a correction parameter and according to the infrared penetration rate of the probe sleeve U sensed by the sensing component T3, so as to obtain a corrected temperature value.
Step S102: an object to be measured is measured by the ear thermometer T to obtain an uncorrected temperature.
In detail, in step S102, the ear thermometer T with the probe cover U already put thereon is used to measure an object to be measured, such as a human body, and an initial temperature (ear temperature) is obtained. However, due to the relationship of the probe cover U itself, it has an infrared transmittance not consistent with the predetermined infrared transmittance stored in the memory unit inside the ear thermometer T. Thus, the initial temperature obtained in this case is actually an uncorrected temperature.
Step S103: according to the uncorrected temperature, the measured penetration rate value, the preset penetration rate value and a radiation energy measurement formula, infrared radiation energy emitted by the object to be measured is obtained.
Step S104: calibrating the uncorrected temperature to a corrected temperature according to a temperature correction function.
Further, in steps S103 and S104, the control component inside the ear thermometer T may be, for example, a Central Processing Unit (CPU) or a Microcontroller (MCU) commonly found in electronic devices, but the invention is not limited thereto. The control component can calculate according to the uncorrected temperature, the measured penetration rate value, the correction parameter and the preset penetration rate value obtained through measurement and according to a radiation energy measurement formula to obtain infrared radiation energy emitted by the object to be measured. Then, the control component calibrates the uncorrected temperature to a corrected temperature according to a temperature correction function. The radiant energy measurement formula comprises the following relation: e = K × ((T)objr）4-（Tamb）4）×tr/td. Wherein E is as describedThe infrared radiation energy emitted by the object to be measured, K is a correction coefficient, TobjrThe uncorrected temperature in the radiant energy measurement formula is expressed in units of Kelvin, TambIs an ambient temperature in units of Kelvin, tdIs the preset penetration value, trThe measured penetration value is used. In the present invention, the ambient temperature TambPreset to 296.15K.
As mentioned above, the temperature correction function includes the following relation: k × ((T)objd）4-（Tamb）4）= td/tr×E= td/tr×K×（（Tobjr）4-（Tamb）4）×tr/td=K×（（Tobjr）4-（Tamb）4). Wherein, TobjdThe corrected temperature of the object to be measured is expressed in units of kelvin. That is, by multiplying the radiant energy measurement formula by td/trSo that K × ((T)objd）4-（Tamb）4） = K×（（Tobjr）4-（Tamb）4) So that said uncorrected temperature T of said object to be measuredobjrCorrected to said corrected temperature Tobjd。
First embodiment
As shown in fig. 4 to 6, the specific features of the sensing assembly T3 on the ear thermometer T provided by the first embodiment of the present invention will be further described. In the present embodiment, the number of sensing elements T3 is set to two, and the number of sensing combinations is set to three. The two sensing elements T3 are divided into a first sensing element T31 and a second sensing element T32, and the three sensing combinations are divided into a first sensing combination, a second sensing combination and a third sensing combination. In addition, it should be noted that, since each sensing element 3 can have both of the on state and the off state, the two sensing elements 3 in the present embodiment can have 4 sensing combinations at most. However, the number of sensing combinations actually used can be adjusted according to the user's needs, and the present invention is not limited to the above examples.
Fig. 4 is a schematic view of a first sensing assembly of the ear thermometer with infrared transmittance for recognizing the probe cover according to the first embodiment of the present invention. The first sensing combination means that the first sensing element T31 is turned on and the second sensing element 32 is turned on. In detail, in the first sensing assembly, the first sensing element T31 on the ear thermometer T is in an open state, i.e. the first sensing element 31 is in a (latch) pressed state, and the first detecting position U301 on the flange U3 of the probe cover U is in a negative detecting state (no hole is formed); the second sensing element T32 of the ear thermometer T is also turned on, i.e. the second sensing element 32 is also pressed (latch), and the second detecting position U302 on the flange U3 of the probe cover U is in a negative detecting state (no opening is formed). That is, both sensing elements T3 on the ear thermometer T are in a (latch) depressed state. In addition, the infrared transmittance of the probe cover U corresponding to the first sensing assembly is set to 80%, in other words, when the probe cover U is sleeved on the probe T2 of the ear thermometer T, the two sensing elements T3 can respectively contact the two detecting positions U30 on the flange U3 of the probe cover U, and the two sensing elements T3 are respectively pressed down by the two detecting positions U30, so that the infrared transmittance of the probe cover U detected by the sensing elements T3 is 80%.
Fig. 5 is a schematic diagram of a second sensing assembly of the ear thermometer with infrared transmittance recognition probe cover according to the first embodiment of the present invention. The second sensing combination means that the first sensing element T31 is in an ON state and the second sensing element T32 is in an OFF state. In detail, in the first sensing assembly, the first sensing element T31 on the ear thermometer T is in an open state, i.e. the first sensing element T31 is in a (latch) pressed state, and the first detecting position U301 on the flange U3 of the probe cover U is in a negative detecting state (no hole is formed); the second sensing element T32 of the ear thermometer T is turned off, i.e., the second sensing element T32 is not pressed, and the second detecting position U302 of the flange U3 of the probe cover U is in a negative detecting state (no hole is formed). That is, only one of the two sensing elements T3 on the ear thermometer T is in the (latch) depressed state. In addition, the infrared transmittance of the probe cover U corresponding to the second sensing assembly is set to 79.5%, in other words, when the probe cover U is sleeved on the probe T2 of the ear thermometer T, the two sensing elements T3 can respectively contact the two detecting positions U30 on the flange U3 of the probe cover U, and the first sensing element T31 of the two sensing elements T3 is pressed down by the two detecting positions U30, so that the infrared transmittance of the probe cover U detected by the sensing element T3 is 79.5%.
Fig. 6 is a schematic diagram of a third sensing assembly of the ear thermometer with infrared transmittance identification probe cover according to the first embodiment of the present invention. The third sensing combination means that the first sensing element T31 is in the OFF state and the second sensing element T32 is in the OFF state. In detail, in the third sensing assembly, the first sensing element T31 on the ear thermometer T is in the off state, i.e. the first sensing element T31 is in the (latch) non-pressed state, and the first detecting position U301 on the flange U3 of the probe cover U is in the positive detecting state (forming the hole); the second sensing element T32 of the ear thermometer T is in the off state, i.e., the second sensing element T32 is also in the non-pressed state (latch), and the second detecting position U302 of the flange U3 of the probe cover U is in the positive detecting state (forming the opening). That is, both sensing elements T3 on the ear thermometer T are in an un-depressed state. In addition, the infrared transmittance of the probe cover U corresponding to the second sensing assembly is set to 80.5%, in other words, when the probe cover U is mounted on the probe T2 of the ear thermometer T, the two sensing elements 3 can respectively contact the two detecting positions U3 on the flange U3 of the probe cover U, and the two sensing elements T3 are not pressed down by the two detecting positions U3, so that the infrared transmittance of the probe cover U detected by the sensing element T3 is 80.5%.
In addition, it should be noted that the infrared transmittance of the probe cover U corresponding to each sensing combination is actually set according to the requirement of the user, and the invention is not limited thereto. Therefore, in other embodiments, the infrared transmittance of the probe cover U corresponding to the first sensing combination, the second sensing combination and the third sensing combination is not necessarily 80%, 79.5% and 80.5% as in this embodiment, and may be other values, such as 81%, 80% and 79%.
Second embodiment

The three sensing elements T3 are divided into a first sensing element T31, a second sensing element T32 and a third sensing element T33, and the five sensing combinations are divided into a first sensing combination, a second sensing combination, a third sensing combination, a fourth sensing combination and a fifth sensing combination. In addition, it should be noted that, since each sensing element T3 can have both the on state and the off state, the three sensing elements T3 in the present embodiment can have at most 8 sensing combinations. However, the number of sensing combinations actually used can be adjusted according to the user's needs, and the present invention is not limited to the above examples.
