Referring to fig. 1 and 5, a testing apparatus 100 is provided in an embodiment of the present disclosure. The testing device 100 is used for acquiring infrared light information of the drying device 200 (shown in fig. 2 and 3) to be tested. The drying device under test 200 is capable of emitting infrared light. The testing apparatus 100 includes a light-equalizing structure 10 and an infrared light testing structure 20. The light equalizing structure 10 has a predetermined area 101 for receiving infrared light and forming a light spot. The predetermined area is provided with a scattering structure 102 for scattering light, the scattering structure 102 covering at least a part of the edge of the spot. The infrared light testing structure 20 includes an image collector 21 and a first processor 22. The image collector 21 is configured to collect an image of a preset area 101 on the light equalizing structure 10, and the first processor 22 is configured to obtain infrared light information according to the image collected by the image collector 21, where the infrared light information includes at least one of whether the light intensity of the infrared light is qualified or not and the light intensity value of the infrared light.
The testing device 100 in the embodiment of the present application provides the scattering structure 102 capable of scattering light by the predetermined region 101 capable of receiving infrared light and forming a light spot in the light-equalizing structure 10, and the scattering structure 102 covers at least a portion of the edge of the light spot. So can carry out the scattering to the light at least some facula edge to make the light of marginal visual field also can go into image collector 21 afterwards, be favorable to promoting the precision that testing arrangement 100 detected.
The following is further described with reference to the accompanying drawings.
Referring to fig. 1, the testing apparatus 100 includes a light-equalizing structure 10 and an infrared testing structure 20, wherein the light-equalizing structure 10 is used for receiving and scattering infrared light emitted by a drying apparatus 200 to be tested (as shown in fig. 2 and 3) and generating light spots. The infrared test structure 20 is used for acquiring infrared light information according to the light spots on the light-homogenizing structure 10. It should be noted that the drying device 200 to be tested can be a blower, a body dryer, a hand dryer, a dryer, etc., and the following embodiments all take the drying device 200 to be tested as a blower as an example for description.
Specifically, the light equalizing structure 10 is disposed on the light path of the drying device 200 to be tested, and the drying device 200 to be tested can emit infrared light along the light path when the drying device 200 to be tested is in operation. The light equalizing structure 10 is now capable of receiving the infrared light emitted by the device to be dried 200. Further, in some embodiments, the light-equalizing structure 10 has a predetermined area 101 for receiving infrared light and forming a light spot, the predetermined area 101 is provided with a scattering structure 102 for scattering light, and the scattering structure 102 covers at least a portion of the edge of the light spot. That is, the infrared light emitted by the drying device 200 to be tested can form a light spot on the preset area 101 of the light-equalizing structure 10, and the scattering structure 102 in the light-equalizing structure 10 can scatter the infrared light.
Usually, the drying device 200 to be tested is controlled to emit radiation light to the transparent member to form a light spot on the transparent member, and the imaging module obtains infrared information of the drying device 200 to be tested according to the light spot. However, since the imaging module collects better to the central field of view and collects worse to the edge field of view, the radiation light passing through the edge of the transparent piece can not completely enter the imaging module to collect the field of view. For example, as shown in fig. 4, the light emitted from the light source is diffused, the light in the middle view field can directly enter the imaging module, and the light in the edge view field (light a and light b in fig. 4) cannot enter the imaging module due to the large deflection angle of the light path, that is, the imaging module cannot collect the light a and the light b, so that only the light in the inside of the view field can be collected actually, and the detection accuracy is affected. Referring to fig. 5, in the embodiment of the present application, the predetermined region 101 for forming the light spot is provided with the scattering structure 102 capable of scattering light, and the scattering structure 102 covers at least a portion of the edge of the light spot. The scattering structure 102 can scatter light at the edge of the light spot, so that light at the edge field can also enter the image collector 21. For example, as shown in fig. 5, the light rays (light rays a and b in fig. 5) in the marginal field of view are scattered by the scattering structure 102, and a part of the light rays a and b are deflected and can enter the image collector 21 after the optical path is changed. That is, the image collector 21 can collect part of the light rays a and b. Therefore, in the embodiment of the application, the scattering structure 102 capable of scattering light is arranged on the preset region 101 for forming the light spot, and the scattering structure 102 at least covers the edge part of the light spot, which is beneficial to improving the detection accuracy of the testing device 100.
Referring to fig. 1, in some embodiments, the light equalizing structure 10 includes a light equalizing element 11, and the light equalizing element 11 is configured to receive infrared light and form a light spot.
For example, referring to fig. 5, in some embodiments, the predetermined area 101 is disposed on the light equalizing member 11, that is, the light equalizing member 11 has the predetermined area 101 for receiving infrared light and forming a light spot. When the drying device 200 to be tested works, the emitted infrared light can be incident to the preset region 101 of the light equalizing member 11 to form a light spot, the preset region 101 of the light equalizing member 11 is provided with the scattering structure 102, and the scattering structure 102 can scatter the infrared light.
Specifically, in some embodiments, the light equalizing member 11 is a semi-transparent structure, and one side of the light equalizing member faces the to-be-dried device 200 to form the light incident surface 111, and the other side of the light equalizing member faces the image collector 21 to form the light emergent surface 112. The scattering structure 102 is disposed on the light incident surface 111 and/or the light emitting surface 112. That is, the scattering structure 102 may be disposed on at least one of the light incident surface 111 and the light emitting surface 112. In this way, the scattering structure 102 can be arranged on at least one surface of the existing molded light homogenizing element 11 according to requirements, and the light homogenizing element 11 does not need to be changed again. Of course, in some embodiments, the light homogenizing element 11 comprises at least one of single-sided frosted glass, double-sided frosted glass, and a volume scattering element.
Referring to fig. 6, in some embodiments, the light-equalizing structure 10 may further include a supporting plate 12 and a transparent member 13. The supporting plate 12 is provided with a through hole 121, and the light equalizing member 11 is arranged in the through hole 121. The transparent member 13 is disposed on a side of the supporting plate 12 close to the drying device 200 to be tested, and at least a portion of the transparent member 13 corresponds to the light-equalizing member 11, so that infrared light can be incident on the light-equalizing member 11 after passing through the transparent member 13.
It should be noted that the drying apparatus 200 to be tested includes a gas flow element (not shown) and one or more radiation sources (not shown). When the drying device 200 to be tested operates, the motor of the airflow component rotates to drive the surrounding air to rotate so as to generate wind in the air channel, the radiation source can emit infrared light along the light path, and the drying device 200 to be tested has the light path and the air channel which are at least partially overlapped. In order to receive the infrared light emitted from the drying device 200 to be tested, the light-equalizing member 11 is necessarily disposed on the light path of the drying device 200 to be tested, so that the light-equalizing member 11 also receives at least part of the wind generated by the drying device 200 to be tested. Since the light equalizing member 11 needs to ensure translucency and have the requirement of astigmatism, the strength is low, and the light equalizing member is easily blown or deformed when being blown by the airflow of the drying device 200 to be tested. However, in the embodiment, the light equalizing member 11 is accommodated in the through hole of the supporting plate 12, and the transparent member 13 is disposed on a side of the light equalizing member close to the drying device 200 to be tested, so that the light equalizing member can be prevented from being blown or deformed by air flow generated by the drying device 200 to be tested, and the service life of the light equalizing member 11 can be prolonged.
When the light-equalizing structure 10 includes the light-equalizing member 11, the supporting plate 12, and the transparent member 13, in some embodiments, the predetermined area 101 of the light-equalizing structure 10 may be disposed on the light-equalizing member 11, that is, the predetermined area 101 of the light-equalizing member 11 is disposed with the scattering structure 102. Specifically, in some embodiments, as shown in fig. 6, the preset structure 101 may further include a first sub-preset region 1011 and a second sub-preset region 1012, and the second sub-preset region 1012 corresponds to the first sub-preset region 1011. The first sub-default region 1011 is provided with a scattering structure 102 for scattering light, and the second sub-default region 1012 is used for receiving infrared light passing through the first sub-default region 1011 and forming a light spot. The first sub-predetermined area 1011 is disposed on the transparent member 13, and the second sub-predetermined area 1012 is disposed on the light-equalizing member. That is, the infrared light emitted by the drying device 200 to be tested can be incident on the first sub-predetermined area 1011 of the transparent member 13, the scattering structure 102 disposed on the first sub-predetermined area 1011 of the transparent member 13 can scatter the infrared light, and then the scattered infrared light can be incident on the second sub-predetermined area 1012 of the light-equalizing member 11, and a light spot is formed on the second sub-predetermined area 1012.
Referring to fig. 1, the infrared light testing structure 20 includes an image collector 21 and a first processor 22. The image collector 21 is located on a side of the light-equalizing structure 10 away from the drying device 200 to be tested, and the image collector 21 is used for collecting an image of the preset area 101 on the light-equalizing structure 10. The first processor 22 is configured to obtain infrared light information according to the image collected by the image collector 21.
For example, when the drying device 200 to be tested is in operation, the infrared light emitted by the drying device 200 can form a light spot in the predetermined area 101 after being emitted onto the light-equalizing structure 10. The image collector 21 collects an image on the preset area 101, wherein the collected image includes a light spot formed on the preset area 101 of the light-equalizing structure 10 through infrared light emission. The image collector 21 may be a camera or a photosensitive sensor.
The first processor 22 then acquires infrared light information from the acquired image. In some embodiments, the infrared light information may be obtained according to the size of the light spot on the preset area 101 of the light-equalizing structure 10. For example, in one example, the infrared light information may include whether the intensity of the infrared light is acceptable. The first processor 22 identifies the spot in the acquired image and calculates the area of the spot. If the calculated light spot area is within the preset light spot area qualified range, the light intensity of the infrared light is qualified, and at the moment, the infrared light information is that the light intensity of the infrared light is qualified; if the calculated light spot area is not in the preset light spot area qualified range, the light intensity of the infrared light is unqualified, and at the moment, the infrared light information is the light intensity of the infrared light which is unqualified. For another example, in one example, the infrared light information may include a light intensity value of the infrared light. After acquiring the light spot area in the acquired image, the first processor 22 may further calculate the light intensity value of the infrared light according to the distance between the drying device 200 to be measured and the light-equalizing structure 10 and the light spot area in the acquired image. Similarly, after a specific light intensity value of the infrared light is acquired, whether the light intensity of the infrared light is qualified or not can be judged according to whether the light intensity value of the infrared light is within a preset qualified light intensity value range or not. The infrared light information thus obtained includes whether or not the light intensity of the infrared light is acceptable, in addition to the specific light intensity value of the infrared light.
In some embodiments, the infrared light information may also be obtained according to the brightness of the light spot on the preset area 101 of the light-equalizing structure 10. In some embodiments, the first processor 22 identifies a spot region in the acquired image and obtains a brightness value for the spot region. In one example, the infrared light information may include whether the intensity of the infrared light is acceptable. After the brightness value of the light spot area is obtained, the obtained brightness value is compared with a preset brightness value, if the brightness value is in a preset brightness value qualified range, the light intensity of the infrared light is qualified, and at the moment, the infrared light information is that the light intensity of the infrared light is qualified; if the brightness value is not in the preset brightness value qualified range, the light intensity of the infrared light is unqualified, and at the moment, the infrared light information is the light intensity of the infrared light is unqualified. For another example, in one example, the infrared light information may include a light intensity value of the infrared light. After obtaining the brightness value of the light spot area, the first processor 22 may further calculate the light intensity value of the infrared light according to the distance between the drying device 200 to be tested and the light-equalizing structure 10 and the brightness value of the light spot area. Similarly, after a specific light intensity value of the infrared light is acquired, whether the light intensity of the infrared light is qualified or not can be judged according to whether the light intensity value of the infrared light is within a preset qualified light intensity value range or not. The infrared light information thus obtained includes whether or not the light intensity of the infrared light is acceptable, in addition to the specific light intensity value of the infrared light.
Of course, in some embodiments, the area of the light spot and the brightness of the light spot area may be combined to obtain the infrared light information, which is not limited herein.
Referring to fig. 1, in some embodiments, the infrared light testing structure 20 further includes a filtering unit 23, and the filtering unit 23 is disposed on the light-equalizing structure 10 and/or the image collector 21. The filter unit 23 only allows light with a predetermined wavelength band to pass through, wherein the predetermined wavelength band at least includes a wavelength band of infrared light emitted by the device under test 200. Therefore, light rays of other wave bands can be filtered, the phenomenon that light rays in the environment are mistakenly used as infrared light emitted by the drying device 200 to be tested is avoided, and therefore the accuracy of the testing device 100 for acquiring infrared light information is further improved.
It should be noted that, in some embodiments, when the filtering unit 23 is disposed on the image collector 21, the filtering unit 23 is disposed on a side of the image collector 21 close to the light-equalizing structure 10, and at this time, the filtering unit 23 only allows light with a preset wavelength band to enter the image collector 21. In some embodiments, when the filtering unit 23 is disposed on the light-equalizing structure 10, the filtering unit 23 may be disposed on a side of the light-equalizing structure 10 close to the drying device 200 to be tested, and/or on a side of the light-equalizing structure 10 close to the image collector 21, where the filtering unit 23 only allows light with a predetermined wavelength band to be emitted from the light-equalizing structure 10.
Referring to FIG. 1, in some embodiments, the testing device 100 is further configured to capture the wind force of the device under test 200. The drying device 200 to be tested has at least partially overlapped light path and air channel, and the testing device 100 further comprises a wind power testing structure 30. The light-homogenizing structure 10 is arranged in a superposition area of the light path and the air channel, and when the drying device 200 to be tested runs, the light-homogenizing structure 10 can also move under the action of wind power. The wind power testing structure 30 is used for obtaining wind power information according to the movement of the light-homogenizing structure 10 under the action of wind power, and the wind power information includes at least one of whether the wind power is qualified and a wind power value.
When the current testing device is used for testing the air volume, the testing device, such as an air velocity tube (pitot tube), an anemometer (impeller type) and the like, needs to be placed on a testing station on an airflow channel for testing. However, because the direction of the light emitted by the drying device to be tested is consistent with the direction of the air flow blown by the air, the testing device can shield the light when placed in the air flow direction for testing the wind power, so that the testing station can not test the light intensity. Namely, the wind power test and the light intensity test must be realized by matching with related test equipment at different stations, so that the cost, the occupied space and the test time of the test equipment are increased. However, in this embodiment, the light-equalizing structure 10 in the overlapping area of the light path and the air duct is utilized to generate movement under the action of wind to obtain the wind information of the drying device 200 to be tested, so that the wind information can be obtained while the light is not blocked, and the light intensity test and the wind power test can be performed by using the same testing device.
When the drying device 200 to be tested operates, the drying device 200 to be tested generates wind along the wind channel and emits infrared light along the light path. At this time, the light-equalizing structure 10 disposed in the overlapping region of the light path and the air duct can receive infrared light, and the light-equalizing structure 10 can move under the influence of wind. It should be noted that the wind generating the moving wind force of the light equalizing structure 10 is all from the wind generated outwards when the drying device 200 to be tested operates. In addition, the movement of the light-equalizing structure 10 under the action of wind includes not only macroscopic relative movement (such as swinging, rotating, sliding, etc.), but also fine deformation of the connection between the light-equalizing structure 10 and other devices.
Specifically, in some embodiments, referring to fig. 7, the wind testing structure 30 may include a bracket 31 and a strain gauge 321. The light-equalizing structure 10 is disposed on the support 31. The stress meter 321 is disposed at a joint of the bracket 31 and the light-equalizing structure 10, and is configured to detect stress change information at the joint of the bracket 31 and the light-equalizing structure 10, so as to obtain wind power information of the drying device 200 to be tested according to the stress change information. Because the stress meter 321 is arranged at the joint of the bracket 31 and the light-equalizing structure 10, the optical radiation information tested by the optical radiation testing structure 20 is not affected when the wind power information is tested, so that the wind power test and the optical radiation test of the drying device 200 to be tested are not required to be realized by different devices at different stations, and the cost and the occupied space of the wind and light testing device 100 are reduced.
It should be noted that, in some embodiments, the light-equalizing member 11 of the light-equalizing structure 10 may be disposed on the support 31, so that the light-equalizing structure 10 is disposed on the support 31. In some embodiments, when the light-equalizing structure 10 includes the supporting plate 12, the supporting plate 12 may be disposed on the support 31 in the light-equalizing structure 10, so that the light-equalizing structure 10 is disposed on the support 31. Of course, other structures in the light-equalizing structure 10 may be disposed on the support 31 as long as the light-equalizing structure 10 can be connected to the support 31, and the present invention is not limited thereto.
For example, the light equalizing structure 10 can slightly deform at the joint with the bracket 31 under the action of wind force, and the stress meter 321 can measure stress change information at the deformed position and obtain wind force information according to the stress change information. For example, in some embodiments, the stress change information includes a stress increase value and the wind information includes whether the wind is acceptable. If the detected stress increment value is within the preset increment value range, the wind power is qualified, and the wind power information is wind power qualified; and if the detected stress increment is not within the preset increment range, the wind power is unqualified, and the wind power information is wind power unqualified. For another example, in some embodiments, the stress change information includes a stress increase value and the wind force information includes a wind force value. After the stress increment is obtained, the wind force value corresponding to the obtained stress increment can be calculated according to the stress increment and the relation function between the stress increment and the wind force value, so that the wind force information is obtained. Similarly, after the specific wind power value is obtained, whether the wind power is qualified or not can be judged according to whether the specific wind power value is within the range of the preset qualified wind power value or not. The wind information thus obtained includes, in addition to the specific wind value, whether the wind is qualified or not.
Referring to FIG. 8, in some embodiments, wind test structure 30 may further include a transfer arm 33 and a load cell 322. The adapter arm 33 is rotatably mounted on the bracket 31 and connected to the light-equalizing structure 10. When the drying device 200 to be tested operates, the light-equalizing structure 10 drives the transfer arm 33 to rotate around the bracket 31 under the action of wind power. The dynamometer 322 corresponds to the transfer arm 33, and the dynamometer 322 is used for detecting stress information of the transfer arm 33 so as to obtain wind power information according to the stress information. Because the deformation of the joint of the light-equalizing structure 10 and the bracket 31 may be small under the action of wind, if the stress change of the joint is directly detected, the stress change of the joint can be accurately detected only by the stress meter with higher accuracy, but the stress meter with higher accuracy has higher cost. In this embodiment, the light-equalizing structure 10 drives the transfer arm 33 to rotate around the bracket 31 under the action of wind, so as to amplify the stress variation at the joint of the light-equalizing structure 10 and the bracket 31. Therefore, in the embodiment, compared with directly obtaining the stress change information of the connection part of the light equalizing structure 10 at the bracket 31 and then obtaining the wind power information according to the stress change information, the method for detecting the stress information of the transfer arm 33 and obtaining the wind power information according to the stress information can reduce the cost of the wind power testing mechanism 30 and is beneficial to improving the testing accuracy of the wind power testing mechanism 30.
It should be noted that, in some embodiments, the transition arm 33 may be connected to the light equalizing member 11 in the light equalizing structure 10. In some embodiments, when the light-equalizing structure 10 includes the support plate 12, the transition arm 33 may be connected to the support plate 12 in the light-equalizing structure 10. Of course, the transition arm 33 may also be continuous with other structures in the light-equalizing structure 10, and is not limited herein.
Furthermore, in some embodiments, the connecting arm 33 may be directly connected to the light-equalizing structure 10. In some embodiments, the connection arm 33 may also be indirectly connected to the light-equalizing structure 10 through an adapter (not shown). The connecting arm 33 is indirectly connected with the light-equalizing structure 10 through the adapter, and compared with the direct connection between the connecting arm 33 and the light-equalizing structure 10, the proportional relation between the movement stroke of the light-equalizing structure 10 and the movement stroke of the adapter arm 33 can be reduced or increased to adapt to the measuring range of the dynamometer 322. For example, the adaptor may be a gear, i.e. the connecting arm 33 may be indirectly connected with the light-homogenizing structure 10 through a gear. Of course, the adaptor may be other members, and is not limited herein.
Illustratively, the light-equalizing structure 10 drives the transfer arm 33 to rotate around the bracket 31 under the action of wind power, and the dynamometer 322 detects the stress information of the transfer arm 33 to obtain the wind power information according to the stress information. For example, in some embodiments, the force information includes a force value of the transfer arm 33, and the wind information includes whether the wind is qualified. If the detected stress value of the transfer arm 33 is within the preset stress value range, the wind power is qualified, and the wind power information is wind power qualified; if the detected stress value of the transfer arm 33 is not within the preset stress value range, the wind power is unqualified, and the wind power information is wind power unqualified. For another example, in some embodiments, the force information includes a force value of the interface arm 33 and the wind information includes a wind force value. After the stress value of the transfer arm 33 is obtained, the wind force value corresponding to the stress value of the transfer arm 33 can be calculated according to the stress value and the relation function between the stress value and the wind force value, so that the wind force information is obtained. Similarly, after the specific wind power value is obtained, whether the wind power is qualified or not can be judged according to whether the specific wind power value is within the range of the preset qualified wind power value or not. The wind information thus obtained includes, in addition to the specific wind value, whether the wind is qualified or not.
Referring to FIG. 1, in some embodiments, the connecting arm 33 is perpendicular to the light-equalizing structure 10, and the force gauge 322 corresponds to the free end 331 of the connecting arm 33. The load cell 322 is used to detect the pressure exerted by the free end 331 to obtain wind force information when the light equalizing structure 10 is rotated and the free end 331 is in contact with the load cell 322. In this case, the load cell 322 may be another load cell 322 capable of detecting pressure, such as an electronic scale, and is not limited herein.
Illustratively, one end of the connecting arm 33 is connected to the light-equalizing structure 10, and the connecting arm 33 is perpendicular to the light-equalizing structure 10. The free end 331 of the connecting arm 33, i.e. the end of the connecting arm 33 remote from the light-equalizing structure 10, corresponds to the load cell 332. When the light-equalizing structure 10 is rotated, the light-equalizing structure 10 can rotate the free end 332 of the connecting arm 33, so that the free end 332 contacts the load cell 322 and applies pressure to the load cell 322. The force gauge 322 can detect the pressure applied by the free end 331 and obtain wind force information according to the detected pressure. Thus, the wind force without the Piao mists can be converted into more intuitive pressure, which is favorable for detecting the wind force information of the drying device 200 to be tested.
For example, in some embodiments, the wind information includes whether the wind is qualified. If the detected pressure value is within the preset pressure value range, the wind power is qualified, and the wind power information is qualified; and if the detected pressure value is not in the preset pressure value range, the wind power is unqualified, and the wind power information is wind power unqualified. For another example, in some embodiments, the wind information includes a wind force value. After the pressure value is obtained, the wind force value corresponding to the detected pressure value can be calculated according to the pressure value and the relation function between the pressure value and the wind force value, so that the wind force information is obtained. Similarly, after the specific wind power value is obtained, whether the wind power is qualified or not can be judged according to whether the specific wind power value is within the range of the preset qualified wind power value or not. The wind information thus obtained includes, in addition to the specific wind value, whether the wind is qualified or not.
In some embodiments, the light homogenizing structure 10 is rotatably mounted to the bracket 31. That is, the light equalizing structure 10 can rotate relative to the bracket 31. At this time, please refer to fig. 8, the wind testing structure 30 may further include a damping unit 34 and an indicating unit 35. The damping unit 34 is disposed at the mounting position of the bracket 31 and the light-equalizing structure 10, and is used for providing damping for the light-equalizing structure 10. Under the condition that the drying device 200 to be tested blows air towards the light-equalizing structure 10, the indicating unit 35 outputs indicating information according to the rotation angle of the light-equalizing structure 10 after overcoming the damping so as to indicate the wind power information of the drying device 200 to be tested. Compared with the method that the connecting arm 33 is arranged at the joint of the light-homogenizing structure 10 and the bracket 31, and the wind power information is indirectly acquired by detecting the stress information of the switching arm 33, the structure of the testing device 100 can be more compact while the wind power information is detected, so that the size of the testing device 100 is reduced.
Illustratively, the damping unit 34, which is disposed at the mounting position of the support 31 and the light-equalizing structure 10, can provide damping for the light-equalizing structure 10, so that the light-equalizing structure 10 can be kept stationary relative to the support 31 without being affected by external force. The light-equalizing structure 10 can rotate relative to the bracket 31 against the damping of the damping unit 34 under the action of wind. At this time, the indicating unit 35 can output indicating information according to the rotation angle of the light equalizing structure 10 after overcoming the damping, so as to indicate the wind power information of the drying device 200 to be tested.
For example, in some embodiments, the indication unit 35 includes an electrical signal generator (not shown), and the indication information includes generation of an electrical signal by the electrical signal generator and non-generation of an electrical signal. The wind power information comprises whether the wind power is qualified or not, and when the indication information indicates that the electric signal generator generates the electric signal, the wind power is qualified at the moment, namely the wind power information is qualified at the moment; when the indication information indicates that the electric signal generator does not generate the electric signal, the wind power is unqualified, namely the wind power information is unqualified. Specifically, under the action of the wind force generated by the drying device 200 to be tested, the light-equalizing structure 10 can rotate relative to the bracket 31 against the damping of the damping unit 34. If the rotation angle after the damping is overcome by 10 is not within the preset angle range, the wind power emitted by the drying device to be tested 200 is unqualified, and the electric signal generator does not generate an electric signal; if the rotation angle of the device 10 after overcoming the damping is within the preset angle range, it indicates that the wind power emitted by the drying device 200 to be tested is qualified at this time, and the electric signal generator generates an electric signal at this time.
For example, in some embodiments, the indication unit 35 may further include a mechanical pointer (not shown), and the indication information includes a deflection angle of the mechanical pointer. The wind power information comprises whether the wind power is qualified, and if the deflection angle of the mechanical pointer is within the preset angle range, the wind power is qualified; and if the deflection angle of the mechanical pointer is not in the preset angle range, the wind power is unqualified, and the wind power information is wind power unqualified. Likewise, in some embodiments, the indication unit 35 may further include a resistance meter (not shown), and the indication information includes a deflection angle of the resistance meter. The wind power information comprises whether the wind power is qualified, and if the deflection angle of the resistance meter is within the preset angle range, the wind power is qualified; if the deflection angle of the resistance meter is not in the preset angle range, the wind power is unqualified, and the wind power information is wind power unqualified.
It should be noted that, in some embodiments, the wind force information includes a wind force value, and the wind force value may be calculated by indicating a function of a deflection angle of the mechanical pointer (or a deflection angle of the resistance meter) in the information and a relationship between the deflection angle of the mechanical pointer and the wind force value (or a relationship between the deflection angle of the resistance meter and the wind force value).
Referring to FIG. 9, in some embodiments, the wind testing structure 30 may further include a guide rail 36. The light homogenizing structure 10 is movably mounted to the guide rail 36. Under the condition that the drying device to be tested 200 blows air towards the light-homogenizing structure 10, the light-homogenizing structure 10 moves along the guide rail 36, and wind power information is acquired according to the moving stroke of the light-homogenizing structure 10 along the guide rail 36. For example, in some embodiments, the wind information includes whether the wind is qualified. If the moving stroke of the light equalizing structure 10 along the guide rail 36 is within the preset stroke range, the wind power is qualified, and at the moment, the wind power information is wind power qualified; if the stroke of the light equalizing structure 10 moving along the guide rail 36 is not within the preset stroke range, the wind power is unqualified, and the wind power information is wind power unqualified. It should be noted that in some embodiments, a scale is further disposed on the guide rail 36 to obtain the stroke of the light-homogenizing structure 10 moving along the guide rail 36.
In some embodiments, the wind test structure 30 may further include a spring 37. The light-equalizing structure 10 is mounted on the guide rail 36 through the elastic member 37, and under the condition that the drying device 200 to be tested blows air towards the light-equalizing structure 10, the light-equalizing structure 10 can overcome the elasticity of the elastic member 37 to move along the guide rail 36 from the initial position, and the elastic member 37 is elastically deformed; in case the drying device under test 200 stops blowing air towards the light homogenizing structure 10, the elastic force of the elastic member 37 can move the light homogenizing structure 10 back to the initial position along the guide rail 36. After the wind power test is completed on the drying device 200 to be tested each time, the light equalizing structure 10 can automatically return to the initial position under the action of the elastic piece 37 so as to perform the next wind power test, so that the light equalizing structure 10 does not need to be reset manually, the detection time is saved, and the operation difficulty of a user on the testing device 100 is reduced.
Further, in some embodiments, the wind test structure 30 may further include a second processor (not shown) for obtaining wind information of the drying device 200 to be tested according to the length of the elastic member 37 after being elastically deformed. For example, in some embodiments, the wind information includes whether the wind is qualified. If the length of the elastic member 37 after elastic deformation is within the preset length range, the wind power is qualified, and the wind power information is qualified; if the length of the elastic member 37 after elastic deformation is not within the preset length range, the wind power is unqualified, and the wind power information is wind power unqualified. For another example, in some embodiments, the wind information includes a wind force value. The second processor obtains the length of the elastic member 37 after elastic deformation, and after obtaining the length of the elastic member 37 after elastic deformation, the second processor may calculate the wind force value according to the length of the elastic member 37 after elastic deformation and a relation function between the length of the elastic member 37 after elastic deformation and the wind force value, so as to obtain the wind force information. Similarly, after the specific wind power value is obtained, whether the wind power is qualified or not can be judged according to whether the specific wind power value is within the range of the preset qualified wind power value or not. The wind information thus obtained includes, in addition to the specific wind value, whether the wind is qualified or not.
Referring to fig. 1, in some embodiments, the testing device 100 may further include a temperature collector 40. The temperature collector 40 is disposed on the light-equalizing structure 10 and is used for collecting the temperature of the light-equalizing structure 10. Since the light-equalizing structure 10 receives the infrared light and the air flow (i.e., the air emitted by the drying device 100 to be tested) at the same time, the infrared light can transfer energy to heat the drying device and the air flow can cool the drying device, and the temperature change of the drying device 200 to be tested in actual operation is difficult to estimate under the combined action of the infrared light and the air flow. However, in the present embodiment, the temperature collector 40 is disposed on the light-equalizing structure 10, and after the temperature of the light-equalizing structure 10 is collected, the temperature sensed by the user when the drying apparatus is actually used can be detected.
It should be noted that, in some embodiments, the infrared light information and the wind power information may also be obtained according to the temperature of the light equalizing structure 10 collected by the temperature collector 40. At the moment, the infrared light information comprises whether the infrared light intensity is qualified or not, and the wind power information comprises whether the wind power is qualified or not. If the temperature of the light equalizing structure 10 is within the preset temperature range, the infrared light intensity is qualified and the wind power is qualified.
Referring to fig. 1, in some embodiments, the testing device 100 further includes an adjustment structure 50. One or more of the light equalizing structure 10, the infrared light testing structure 20, and the wind force testing structure 30 are disposed on the adjusting structure 50. Wherein at least one of the light equalizing structure 10, the infrared light testing structure 20, and the wind power testing structure 30 is movable relative to the adjusting structure 50. Because at least one of the light equalizing structure 10, the infrared light testing structure 20 and the wind power testing structure 30 can move relative to the adjusting structure 50, a user can adjust the distance between the light equalizing structure 10, the infrared light testing structure 20 and the wind power testing structure 30 according to requirements, and the drying device 200 to be detected can be detected according to different requirements.
Referring to fig. 1 and 3, in some embodiments, the testing apparatus 100 further includes a fixing tool 60 and a stage 70. The fixing tool 60 is used for installing the drying device 200 to be tested, and the rack 70 is used for installing the fixing tool 60 and the adjusting structure 50. The adjusting structure 50 comprises a limiting shaft 51, and one or more of the light equalizing structure 10, the infrared light testing structure 20 and the wind power testing structure 30 which are arranged on the adjusting structure 50 can move along the limiting shaft 51. That is, the structure provided on the adjustment structure 50 can move along the stopper shaft 51. For example, in some embodiments, the light-equalizing structure 10 is disposed on the adjusting structure, so that the light-equalizing structure 10 can move along the limiting shaft 51; alternatively, in some embodiments, the light equalizing structure 10 and the infrared light testing structure 20 are disposed on the adjusting structure, so that the light equalizing structure 10 and the infrared light testing structure 20 can move along the limiting shaft 51; alternatively, in some embodiments, the light equalizing structure 10, the infrared light testing structure 20, and the wind power testing structure 30 are disposed on the adjusting structure, so that the light equalizing structure 10, the infrared light testing structure 20, and the wind power testing structure 30 can move along the limiting shaft 51. In addition, the drying device 200 to be tested mounted on the fixing tool 60 can emit infrared light and blow air toward the adjusting structure 50, and the limiting shaft 51 is parallel to the optical path of the drying device 200 to be tested mounted on the fixing tool 60. Because the limiting shaft 51 is parallel to the optical path of the drying device 200 to be tested installed on the fixed tool 60, that is, the direction in which one or more of the light equalizing structure 10, the infrared light testing structure 20 and the wind power testing structure 30 can move is parallel to the optical path of the drying device 200 to be tested installed on the fixed tool 60, so that no matter how the user adjusts the drying device, the light equalizing structure 10, the infrared light testing structure 20 and the wind power testing structure 30 can not deviate, and the normal operation of the testing device 100 is prevented from being influenced.
Referring to fig. 1 and 10, in some embodiments, the fixing tool 60 includes a substrate 61, a base 62, and a limiting frame 63. In particular, the substrate 61 is provided with an electrical interface 611. The base 62 is disposed on the substrate 61, and the base 62 is used for carrying the handheld portion 210 of the drying device 200 to be tested. An electrical interface 611 on the substrate 61 corresponds to the base 62, and the electrical interface 611 is used for electrically connecting the handle 210 and an external device to realize data transmission. That is, the drying device 200 to be tested performs data transmission with the external device through the electrical interface 611. The drying device 200 to be tested installed on the fixed tool 60 can realize data transmission with external equipment, the drying device 200 to be tested is conveniently controlled through the external equipment, and quick testing is favorably realized.
The limiting frame 63 is disposed on the substrate 61, and the limiting frame 63 is used for bearing the air outlet portion 220 of the drying device 200 to be tested, so that at least part of the infrared light emitted by the drying device 200 to be tested passes through the light equalizing structure 10. Therefore, before the drying device 200 to be tested is detected each time, only the air outlet part 220 needs to be directly borne on the limiting frame 63, and at least part of infrared light in the infrared light emitted by the drying device 200 to be tested can pass through the light equalizing structure 10 without debugging for many times by a user, so that the rapid test can be realized, and the complexity of using the testing device 100 by the user can be reduced.
