[0023] Combine the following Figure 1 The utility model describes an infrared moisture meter capable of eliminating fog.
[0024] like Figure 1 As shown, in an embodiment of the utility model, the infrared moisture meter includes: a main body 10, a probe 20 and a defogger. The probe 20 includes a probe 21 and a cover 22. The cover 22 is arranged outside the probe 21. The cover 22 is connected to the main body 10, and the probe 21 is also connected to the main body 10. The defogger is connected to the cover 22. The defogger removes the fog when the probe 21 surface is fogged by compressed air or heating the probe 21.
[0025] Specifically, in this embodiment, the optical structure and electrical structure of the infrared moisture meter are the same as those in the prior art. In the prior art, the main body 10 is directly connected to the probe 21. In the embodiment of the utility model, a cover body 22 is arranged between the main body 10 and the probe 21, and the space inside the cover body 22 is used to eliminate the fog on the glass sheet of the probe 21.
[0026] Optionally, in an embodiment of the utility model, the defogger mechanism can use compressed air to remove the fog on the probe 21. Specifically, the defogger mechanism includes a pipe 31 and a compressed air source 32. The compressed air source 32 is connected to the cover body 22 through the pipe 31, so that the compressed air is delivered to the cover body 22. The compressed air blows the glass sheet of the probe 21 to remove the fog on the probe 21.
[0027] Optionally, in another embodiment of the utility model, the defogger mechanism may also utilize the air in the heating cover 22 to increase the temperature of the glass sheet of the probe 21, so that when the infrared moisture meter encounters moisture at a higher temperature, the temperature of the probe 21 is not much different from the moisture temperature, and thus it is not easy for fog to form on the surface of the probe 21; or when fog is formed on the surface of the probe 21, the probe 21 may be heated to eliminate the fog.
[0028] The infrared moisture meter capable of eliminating fog provided by the embodiment of the utility model can remove fog when fog occurs on the probe surface by means of a cover body and a defogger mechanism, using compressed air or heating the probe, thereby ensuring the detection accuracy of the infrared moisture meter.
[0029] like Figure 1 As shown, in an embodiment of the present invention, the infrared moisture meter further includes a light sensing element 40 , which is disposed in the cover 22 and opposite to the probe 21 , and is used to detect the area of fog on the surface of the probe 21 .
[0030] Specifically, the light sensing element 40 detects the area of fog on the probe 21 surface using the intensity of light passing through the probe 21 . When the fog coverage area on the probe 21 surface is greater than a preset value, the defogger mechanism is activated to remove the fog on the probe 21 surface.
[0031] Optionally, the light sensing element 40 may be a photoelectric coupler, a photoresistor or a photoelectric switch.
[0032] Furthermore, in the embodiment of the present utility model, the infrared moisture meter further includes a controller, and the controller is electrically connected to the light sensing element 40 and the defogger mechanism.
[0033] Specifically, when the infrared moisture meter detects the moisture in the material, the photosensitive element 40 detects the area of fog on the surface of the probe 21 in real time. When the area of fog is greater than a preset value, the photosensitive element 40 sends a signal to the controller, and the controller controls the defogger mechanism to turn on to eliminate the fog on the probe 21, thereby ensuring the accuracy of the probe 21 during detection.
[0034] like Figure 1 As shown, in the embodiment of the utility model, the demisting mechanism includes: a first demisting mechanism and a second demisting mechanism. The first demisting mechanism is connected to the cover body 22, and the first demisting mechanism is used to pass compressed air into the cover body 22 to remove the mist on the surface of the probe 21. The second demisting mechanism is arranged in the cover body 22, and the second demisting mechanism is used to heat the probe 21 to remove the mist on the surface of the probe 21.
[0035] Specifically, the first demisting mechanism includes: a pipe 31 and a compressed air source 32, and both ends of the pipe 31 are respectively connected to the compressed air source 32 and the cover body 22. When the surface of the probe 21 is fogged, the compressed air is blown to the surface of the probe 21 to remove the fog on the surface of the probe 21.
[0036] Furthermore, in an embodiment of the present utility model, the first defogger mechanism further includes a switch valve 33 , the switch valve 33 is disposed in the pipeline 31 , and the switch valve 33 is electrically connected to the controller.
[0037] Specifically, when the infrared moisture meter detects the moisture in the material, the photosensitive element 40 detects the area of the fog on the surface of the probe 21 in real time. When the area of the fog is greater than the preset value, the photosensitive element 40 sends a signal to the controller, and the controller controls the switch valve 33 to open, and compressed air enters the cover body 22 from the compressed air source 32 to remove the fog on the surface of the probe 21.
[0038] After the mist is eliminated, the controller controls the switch valve 33 to close. When the area of the mist on the surface of the probe 21 reaches the preset value again, the controller controls the switch valve 33 to open again to eliminate the mist.
[0039] Furthermore, in the embodiment of the present utility model, the pressure of the compressed air source 32 is less than or equal to 0.1 MPa to prevent the compressed air pressure from being too high and affecting the detection accuracy of the infrared moisture meter.
[0040] The infrared moisture meter capable of eliminating fog provided by the embodiment of the utility model can detect the area of fog on the probe surface in real time by setting a photosensitive element and a controller, and control the first defogger to open when the fog area is larger than a preset value, thereby eliminating fog in real time and ensuring the detection accuracy of the infrared moisture meter; and after the fog is eliminated, the first defogger can be closed in time to avoid energy waste.
[0041] like Figure 1As shown, in the embodiment of the present utility model, the second defogger mechanism includes a heating wire 50, the inner wall surface of the cover body 22 is provided with a spiral groove, and the heating wire 50 is arranged in the spiral groove.
[0042] Specifically, the inner wall surface of the cover body 22 is provided with a spiral groove, and the electric heating wire 50 is spirally wound around the inner wall of the cover body 22. When the electric heating wire 50 is heated, the air in the cover body 22 can be heated, thereby increasing the temperature of the probe 21. When the moisture with a higher temperature in the material meets the probe 21 with a lower temperature, fog will form on the surface of the probe 21, and when the temperature of the probe 21 is close to the temperature of the moisture in the material, no fog will be generated on the surface of the probe 21. Therefore, the electric heating wire 50 is arranged in the cover body 22, which can prevent the generation of fog, thereby ensuring the detection accuracy of the infrared moisture meter.
[0043] like Figure 1 As shown, in the embodiment of the present utility model, the second defogger mechanism further includes a switch 60 , which is disposed on the outer wall surface of the cover body 22 , and the switch 60 is electrically connected to the heating wire 50 .
[0044] Specifically, when the ambient temperature is low, the temperature of the surface of the probe 21 is low. At this time, when the higher temperature moisture in the material encounters the lower temperature probe 21, it is very easy to generate fog on the surface of the probe 21. A switch 60 is set outside the cover body 22. When the ambient temperature is low, the switch 60 can be pressed to energize the heating wire 50, thereby ensuring the constant temperature inside the cover body 22, thereby preventing fog from being generated on the surface of the probe 21.
[0045] Furthermore, in an embodiment of the present invention, the infrared moisture meter also includes a temperature sensor 70, which is disposed on the outer wall of the cover body 22. The temperature sensor 70 is used to detect the ambient temperature. The temperature sensor 70 and the switch 60 are both electrically connected to the controller.
[0046] Specifically, the temperature sensor 70 is used to detect the ambient temperature. When the ambient temperature is lower than a preset value, the temperature sensor 70 sends a signal to the controller, and the controller controls the switch 60 to turn on to heat the probe 21 .
[0047] It should be noted that: in this embodiment, the preset value can be specifically set according to the temperature of the water in the material.
[0048] Further, in the embodiment of the utility model, the first defogger mechanism and the second defogger mechanism can work separately or simultaneously. Specifically, when the ambient temperature is high, the fog area generated on the surface of the probe 21 is small. When fog is generated on the surface of the probe 21, the first defogger mechanism can be controlled to work separately, and the fog on the surface of the probe 21 can be removed by compressed air. When the ambient temperature is low, the fog area generated on the surface of the probe 21 is large, and the surface of the probe 21 is very easy to generate fog. At this time, the second defogger mechanism can be controlled to work first, and the heating wire 50 can be heated to prevent the surface of the probe 21 from fogging. If the power of the heating wire 50 is small and the ambient temperature is low, there is still fog on the surface of the probe 21 after the heating wire 50 is heated, then the first defogger mechanism can be turned on at the same time, and the fog on the surface of the probe 21 can be removed by compressed air.
[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
