[0038] See Figure 1 As shown, a portable external auditory canal detector includes a main unit 100, a detection line 200, a sensing probe 300, and a protective ear cap 500. The detection line 200 is electrically connected to the main unit 100. The sensing probe 300 is disposed at one end of the detection line 200 away from the main unit 100 and is used to extend into the ear canal to detect humidity. The protective ear cap 500 includes an abutting portion 510 and a clamping portion. The abutting portion 510 is connected to the clamping portion, and the clamping portion is detachably connected to the detection line 200. Wherein, the position of the abutting portion 510 on the detection line 200 is lower than the position of the sensing end of the sensing probe 300 on the detection line 200. When the detection line 200 extends into the ear canal, the abutting portion 510 abuts against the ear canal, and the sensing end of the sensing probe 300 is exposed in the ear canal.

[0039] Specifically, in this embodiment, a portable external auditory canal detector is disclosed, which includes a main unit 100, a detection line 200, a sensing probe 300, and a protective ear cap 500. The main unit 100 generally refers to an integrated device, which is used to receive the signal of the sensing probe 300 and process the signal of the sensing probe 300 for display. The sensing probe 300 is disposed at one end of the detection line 200 away from the main unit 100 and is used to extend into the ear canal to detect humidity.

[0040] Furthermore, in this embodiment, a protective ear cap 500 is also disclosed. The protective ear cap 500 includes an abutting portion 510 and a clamping portion. The abutting portion 510 is connected to the clamping portion, and the clamping portion is detachably connected to the detection line 200. Wherein, the position of the abutting portion 510 on the detection line 200 is lower than the position of the sensing end of the sensing probe 300 on the detection line 200. "Lower" means that the abutting portion 510 does not block the sensing end of the sensing probe 300. When the detection line 200 extends into the ear canal, the abutting portion 510 abuts against the ear canal, avoiding excessive penetration and causing damage to the patient's ear canal. The sensing end of the sensing probe 300 is exposed in the ear canal. The sensing end refers to the part of the sensing probe 300 for detection. In this way, only by exposing the sensing end of the sensing probe 300 can the detection effect of the sensing probe 300 be ensured, while improving the detection accuracy of the sensing probe 300 without damaging the patient's ear canal.

[0041] SeeFigure 2 and Figure 3 As shown in Figure 3 , in another embodiment of the present application, one end of the detection line 200 facing away from the host 100 has a first connection portion 210 and a second connection portion 220. One end of the first connection portion 210 is connected to the end of the detection line 200 facing away from the host 100, and the other end is connected to the second connection portion 220. The sensing probe 300 is provided on the second connection portion 220. The first connection portion 210 is cylindrical in shape, and the second connection portion 220 is trumpet-shaped; a channel 511 is formed at the middle position of the abutting portion 510 and is sleeved on the first connection portion 210; the engaging portion includes a plurality of elastic strips 520, and the plurality of elastic strips 520 are arranged on the abutting portion 510 along the periphery of the channel 511. The plurality of elastic strips 520 are used to pass through the first connection portion 210 and are engaged and connected to the second connection portion 220.

[0042] Specifically, this embodiment provides a specific way of detachably connecting the detection line 200 and the protective earplug 500. When the protective earplug 500 needs to be replaced, a channel 511 is formed in the middle of the abutting portion 510 of the protective earplug 500. The channel 511 is used to be sleeved on the first connection portion 210 of the detection line 200. The engaging portion includes a plurality of elastic strips 520, and the plurality of elastic strips 520 are arranged on the abutting portion 510 along the periphery of the channel 511. Since the second connection portion 220 is trumpet-shaped and the diameter gradually increases, the elastic strips 520 are engaged on the second connection portion 220, so that the protective earplug 500 is engaged and connected to the detection line 200. It can be understood that the position of the protective earplug 500 is lower than the sensing end position of the sensing probe 300. At this time, the protective earplug 500 does not block the sensing probe 300. More specifically, the abutting portion 510 of the protective earplug 500 is hemispherical in shape, the outer diameter is preferably 10 mm, and the inner diameter of the middle channel 511 for the first connection portion 210 to pass through is set to 6.5 mm. In this embodiment, by setting the cooperation relationship between the protective earplug 500 and the detection line 200, the protective earplug 500 is engaged on the detection line 200, the structure is simple, and the assembly process is simplified, which is convenient for maintenance and replacement.

[0043] Furthermore, in this embodiment, the elastic strips 520 are also disclosed. The plurality of elastic strips 520 are arranged on the abutting portion 510 along the periphery of the channel 511. Preferably, the number of the elastic strips 520 is four, and there is a gap between each elastic strip 520. Each elastic strip 520 is a plastic strip, and the plastic can be made of elastic plastic materials such as polypropylene and silica gel, so that the elastic strip 520 has elasticity and is convenient for being engaged on the second connection portion 220.

[0044] In another embodiment of the present application, the diameter of the channel 511 is the same as the diameter of the first connecting portion 210, and the diameter of the first connecting portion 210 is smaller than the diameter of the second connecting portion 220.

[0045] Specifically, when the abutting portion 510 passes through the first connecting portion 210, the abutting portion 510 has the same diameter as the first connecting portion 210. The diameter of the first connecting portion 210 is smaller than the diameter of the second connecting portion 220. The abutting portion 510 is limited by the second connecting portion 220 to prevent the protective earplug 500 from moving on the first connecting portion 210 and the second connecting portion 220, which is beneficial to improving the use stability of the protective earplug 500.

[0046] See Figure 3 As shown, in another embodiment of the present application, a protective shell 400 is sleeved on the sensing probe 300. The protective shell 400 is fixedly connected to the detection line 200, and a through hole 410 is provided on the protective shell 400.

[0047] In this embodiment, the protective shell 400 is disclosed. The shape of the protective shell 400 can be correspondingly set according to the shape of the sensing probe 300, such as cylindrical, cuboid, etc. The protective shell 400 is sleeved on the sensing probe 300 and fixedly connected to the detection line 200, so as to protect the sensing probe 300. It can be understood that the through hole 410 is provided on the side wall of the protective shell 400, and the through hole 410 is provided to enable the sensing probe 300 to contact the air in the patient's ear canal without affecting the normal use of the sensing probe 300.

[0048] The protective shell 400 disclosed in this embodiment is made of a transparent material, such as polycarbonate (PC), polyvinyl chloride (PVC), etc., so that users can directly observe the situation of the internal sensing probe 300.

[0049] Furthermore, in another embodiment of the present application, a waterproof and breathable membrane is provided on the through hole 410. Specifically, the waterproof and breathable membrane is a polymer material membrane that can allow gas to pass through but not liquid water. The main component of this material is usually expanded polytetrafluoroethylene (e-PTFE), but it may also contain other polymers, such as polyester (PET), polyethersulfone (PES), polyamide (Nylon), polyvinylidene fluoride (PVDF), polypropylene (PP), etc., depending on the application requirements, so as to effectively protect the sensing probe 300, improve the safety of the sensing probe 300, and in addition, prevent cross-infection between patients.

[0050] Furthermore, in another specific embodiment of the present application, the waterproof and breathable membrane is a polytetrafluoroethylene membrane. Specifically, the polytetrafluoroethylene membrane is also known as PTFE, which has good chemical stability, high temperature resistance, and non-stick properties. The waterproof and breathable membrane made of polytetrafluoroethylene membrane is stable, reliable, and low in cost.

[0051] In another embodiment of the present application, the protective earplug 500 is a silicone protective earplug 500. Silicone refers to silicone material. By using the protective earplug 500 made of silicone, the head 510 of the protective earplug 500 has certain elasticity and deformation ability, making it soft and comfortable when inserted into the patient's ear canal, thus improving the comfort level.

[0052] In another embodiment of the present application, the sensing probe 300 is a humidity sensor. By using the humidity sensor to detect the air in the patient's ear canal, the humidity in the ear canal can be measured.

[0053] See Figure 1 As shown, in another embodiment of the present application, a display 110 is provided on the host 100. The display 110 is electrically connected to the host 100, and the display 110 is used to display the detection result of the sensing probe 300. Specifically, the display 110 is installed on the front of the host 100. By displaying the detection result of the sensing probe 300 through the display 110, it is convenient for the user to view.

[0054] Further, see Figure 1 and Figure 4 As shown, in another embodiment of the present application, a reminder module is provided on the host 100. The host 100 is electrically connected to the reminder module, and the reminder module is used to issue a reminder when the detection result of the sensing probe 300 is greater than a predetermined target.

[0055] Specifically, the reminder module of the present application is installed inside the host 100 and is electrically connected to the host 100. For example, a predetermined target is set on the display 110. The predetermined target refers to a predetermined humidity value. Under normal conditions, the predetermined humidity value of the patient is generally 20 - 30 degrees, preferably 25 degrees; when the detection result of the sensing probe 300 is greater than the set predetermined target, the sensing probe 300 sends the detection result to the host 100. The host 100 analyzes and processes to determine whether it is greater than the predetermined target. When the detection result is greater than the predetermined target, the host 100 controls the reminder module to issue a reminder to the patient. It can be understood that there are various reminder modes for the reminder module. For example, an alarm is electrically connected to the host, and an alarm reminder is given through the alarm.

[0056] In summary, the present utility model provides a portable external auditory canal detector. By providing a detachable protective ear sleeve on the sensing probe, the protective ear sleeve can abut against the patient's ear canal to prevent excessive penetration and cause damage to the patient's external auditory canal. The sensing probe is exposed on the protective ear sleeve, which can accurately detect the humidity in the patient's ear canal. The detachable protective ear sleeve is convenient for replacement and avoids cross-infection between patients.

[0057] It should be understood that the application of the present utility model is not limited to the above examples. For those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations shall fall within the protection scope of the appended claims of the present utility model.
