Fig. 1 to 4 are schematic perspective views of an ear thermometer with infrared transmittance of a recognition probe cover according to the present invention, fig. 1 is a schematic partial sectional view of the ear thermometer with infrared transmittance of a recognition probe cover according to the present invention, fig. 3 is a schematic functional block diagram of the ear thermometer with infrared transmittance of a recognition probe cover according to the present invention, and fig. 4 is a schematic diagram of the ear thermometer with infrared transmittance of a recognition probe cover according to the present invention and the probe cover. The invention provides an ear thermometer T capable of identifying the infrared penetration rate of a probe sleeve U, which comprises an ear thermometer body 1, a probe 2 and a plurality of sensing assemblies 3. The probe 2 is arranged on the ear thermometer body 1. The probe can be provided with a probe sleeve U sleeved on the probe. The probe cover U has a closed end U1 through which the infrared radiation passes, i.e., the point through which the infrared radiation passes primarily, and the closed end U1 has a different infrared radiation transmission rate depending on the thickness of the closed end 11. The closed end 11 itself has a 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 11. Thus, the probe cover U will have a different infrared transmission rate depending on the change in thickness of the closed end 11. In addition, it should be noted that the probe cover U provided by the embodiment of the present invention may be an integrally formed hard earmuff.
A plurality of sensing assemblies 3 are disposed on the ear thermometer body 1 and adjacent to the probe 2. The plurality of sensing assemblies 3 are used for sensing the infrared ray penetration rate of the probe cover U. Further, each sensing element 3 includes an on state and an off state, so that the plurality of sensing elements 3 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 in the plurality of different sensing combinations are different from each other.
In view of the above, further, since the probe cover U provided by the present invention is sleeved on the probe 2 of the ear thermometer T, the flange U2 of the probe cover U has a plurality of detecting positions U3 corresponding to the plurality of sensing elements 3 of the ear thermometer T. When the probe cover U is fitted over the probe 2 of the ear thermometer T, the sensing elements 3 can contact the detecting positions U3 on the flange U2 of the probe cover U, and thereby detect the infrared transmittance of the probe cover U. That is, the sensing elements 3 can detect the infrared ray penetration rate of different probe covers U by using different sensing combinations arranged and combined at the detecting positions U3 on the flange U2 of the probe cover U.
In addition, the ear thermometer T further comprises at least one protrusion 6. A boss 6 is provided on the ear thermometer body and adjacent to the probe. In the present invention, the number of the projections 6 is two, but the present invention is not limited thereto. The ear thermometer T of the present invention is configured such that the plurality of sensing elements 3 of the ear thermometer T are brought into correspondence with the plurality of detecting positions U3 on the flange U2 of the probe cover U by engaging the concave portions U4 on the flange U2 of the probe cover U of the convex portion 6. Through the design of the convex part 6, the situation that the plurality of detecting positions U3 cannot align with the plurality of sensing assemblies 3 due to the rotation of the probe sleeve U when the probe sleeve U is sleeved on the probe 2 of the ear thermometer T can be avoided.
It should be noted that, in the embodiments of the present invention, the plurality of sensing elements 3 are elastic mechanical pins capable of being pressed, the on state of each sensing element 3 is a pin-pressing state, and the off state of each sensing element 3 is a pin-non-pressing state. That is, when the probe cover U is fitted over the probe 2 of the ear thermometer T, the sensing elements 3 on the ear thermometer T are not pressed or not pressed by the detecting positions U3 on the flange U2 of the probe cover U, so that the sensing elements 3 do not send out a sensing signal or send out at least one sensing signal. However, the present invention is not limited thereto, and in other embodiments of the present invention, the on state and the off state of the sensing element 3 may be in other forms, for example, the sensing element 3 may be a photoelectric switch (photoelectric sensor), and the light beam emitted by the photoelectric switch is blocked or transmitted by the light transmission/non-light transmission of the plurality of detecting positions U3 on the flange U2 of the probe cover U, so as to detect the infrared transmittance of the probe cover U. The on state of the sensing element 3 is the state that the light beam emitted by the photoelectric switch is shielded, and the off state of the sensing element 3 is the state that the light beam emitted by the photoelectric switch is not shielded.
The ear thermometer T further comprises an infrared detecting element 4 and a control element 5. The infrared detecting component 4 is disposed inside the ear thermometer body 1. When the probe sleeve U is sleeved on the probe 2 of the ear thermometer T, the infrared rays can pass through the probe sleeve U and enter the interior of the ear thermometer body 1 through the probe 2. The control component 5 is arranged inside the ear thermometer body 1, and the control component 5 is electrically connected with each sensing component 3. When each sensing element 3 is in an open state (i.e. a pin-down state), each sensing element 3 will send a sensing signal to the control element 5. Therefore, a plurality of different sensing combinations formed by the plurality of sensing elements 3 (for example, one sensing element 3 is in an on state, and the other sensing element 3 is in an off state) do not send out a sensing signal or send out at least one sensing signal to the control element 5. The control component 5 can recognize the infrared transmittance of the probe cover U according to the received sensing signal (or not receiving the sensing signal).
The operation principle of the ear thermometer T will be described next. The infrared ray entering the inside of the ear thermometer body 1 is received by the infrared ray detecting element 4 and outputs a detecting signal S1. It should be noted that the infrared ray referred to herein is mainly an infrared ray emitted from a human body. The control unit 5 is electrically connected to the infrared detecting unit 4, so that the control unit 5 receives the detecting signal and converts the detecting signal into an initial temperature value. The control component 5 may be, for example, a Central Processing Unit (CPU) or a Microcontroller (MCU) as is common in electronic devices, but the present invention is not limited thereto. The control device 5 includes a memory 51, and the memory 51 stores a predetermined infrared transmittance value and a transmittance calibration parameter. The control component 5 corrects the sensed initial temperature according to the preset infrared penetration value and penetration correction parameter and according to the infrared penetration of the probe cover U sensed by the sensing component 3, so as to obtain a corrected temperature value.

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.

That is, both sensing elements 3 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 2 of the ear thermometer T, the two sensing elements 3 can respectively contact the two detecting positions U3 on the flange U2 of the probe cover U, and the two sensing elements 3 are respectively pressed down by the two detecting positions U3, so that the infrared transmittance of the probe cover U detected by the sensing elements 3 is 80%.

That is, only one of the two sensing elements 3 on the ear thermometer T is in a (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 mounted on the probe 2 of the ear thermometer T, the two sensing elements 3 can respectively contact the two detecting positions U3 on the flange U2 of the probe cover U, and the first sensing element 31 of the two sensing elements 3 is pressed down by the two detecting positions U3, so that the infrared transmittance of the probe cover U detected by the sensing elements 3 is 79.5%.

That is, both sensing elements 3 on the ear thermometer T are in an (inserted pin) non-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 2 of the ear thermometer T, the two sensing elements 3 can respectively contact the two detecting positions U3 on the flange U2 of the probe cover U, and the two sensing elements 3 are not pressed down by the two detecting positions U3, so that the infrared transmittance of the probe cover U detected by the sensing elements 3 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%.

That is, only one of the three sensing elements 3 of the ear thermometer T is in the (latch) pressed state. In addition, the infrared transmittance of the probe cover U corresponding to the fourth sensing assembly is set to 79.5%, in other words, when the probe cover U is mounted on the probe 2 of the ear thermometer T, the three sensing elements 3 can respectively contact the three detecting positions U3 on the flange U2 of the probe cover U, and the third sensing element 33 of the three sensing elements 3 is pressed down by the three detecting positions U3, so that the infrared transmittance of the probe cover U detected by the sensing elements 3 is 79.5%.
Fig. 12 is a schematic view of a fifth sensing assembly of the ear thermometer with infrared transmittance of the identification probe cover according to the second embodiment of the present invention. The fifth sensing combination means that the first sensing element 31, the second sensing element 32 and the third sensing element 33 are all in the off state. In detail, in the fifth sensing combination, the first sensing element 31 on the ear thermometer T is in the off state, i.e. the first sensing element 31 is in the (latch) non-pressed state; the second sensing element 32 of the ear thermometer T is also in the off state, i.e. the second sensing element 32 is also in the (latch) non-pressed state; the third sensing element 33 of the ear thermometer T is also in the off state, i.e. the third sensing element 33 is also in the (latch) non-pressed state. That is, the three sensing elements 3 of the ear thermometer T are in the non-depressed state. In addition, the infrared transmittance of the probe cover U corresponding to the fifth sensing assembly is set to 79%, in other words, when the probe cover U is mounted on the probe 2 of the ear thermometer T, the three sensing elements 3 can respectively contact the three detecting positions U3 on the flange U2 of the probe cover U, and any one of the three sensing elements 3 (the first sensing element 31, the second sensing element 32 and the third sensing element 33) is not pressed down by the three detecting positions U3, so that the sensing element 3 detects that the infrared transmittance of the probe cover U is 79%.
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, the third sensing combination, the fourth sensing combination and the fifth sensing combination is not necessarily 80%, 80.5%, 81%, 79.5% and 79% as in the present embodiment, but may be other values, such as 82%, 81%, 80%, 79% and 78%.
The ear thermometer T with the function of identifying the infrared penetration rate of the probe sleeve U can sense the infrared penetration rate of the probe sleeve U through a plurality of sensing assemblies 3 arranged on the ear thermometer body 1 and each sensing assembly 3 comprises an opening state and a closing state, so that the sensing assemblies 3 are arranged and combined into a plurality of different sensing combinations, and the different sensing combinations respectively correspond to different infrared penetration rates, so that the ear thermometer T can quickly identify the penetration rate of the probe sleeve U sleeved on the ear thermometer T.
Further, the ear thermometer T can avoid the situation that the plurality of detecting positions U3 cannot align with the plurality of sensing elements 3 due to the rotation of the probe cover U when the probe cover U is sleeved on the probe 2 of the ear thermometer T by engaging the concave portions U4 on the flange U2 of the probe cover U of the convex portion 6.
It is to be emphasized that: the above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and all simple modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention are within the scope of the technical solution of the present invention.
