[0036] The utility model provides a device 100 for detecting the life of a blower. Specifically, please refer to Figures 1 to 2In this embodiment, the air duct life detection equipment 100 includes a detection box 1, a detection fixture 2, a suction device 3 and an electronic control device 4. The detection box 1 is hollow and is provided with an air inlet channel and an air outlet channel suitable for connecting the outside and its inner cavity; the detection fixture 2 is provided on one side of the detection box 1 and is suitable for fixing the air duct 200 thereon, so that the air outlet of the air duct 200 is suitable for communicating with the air inlet channel; the suction device 3 is connected to the air outlet channel, and the air flow blown out of the air outlet of the air duct 200 can enter the detection box 1 from the air inlet channel and be discharged from the air outlet channel under the action of the suction device 3; the electronic control device 4 is suitable for being electrically connected to the air duct 200 placed on the detection fixture 2.

[0037] In this embodiment, an air inlet channel and an air outlet channel are provided on the detection box 1, and a detection fixture 2 is provided on one side of the detection box 1. The detection fixture 2 can be used to fix the air duct 200 outside the detection box 1 so that the air outlet of the air duct 200 is connected to the air inlet channel. The electric control device 4 can provide power to the air duct 200. When performing a test, the air duct 200 can be turned on so that the air flow blown out of the air outlet of the air duct 200 can enter the detection box 1 through the air inlet channel and be discharged from the air outlet channel under the action of the suction device 3 to be discharged outside the detection environment, thereby preventing the detection environment temperature from rising and affecting the accuracy of the test. In addition, the electric control device 4 can be electrically connected to the air duct 200 and can obtain the operating data of the air duct 200, such as the voltage or current during the operation of the air duct 200, so as to understand the working status of the air duct 200 in real time, making the detection results of the air duct 200 more accurate and reliable.

[0038] The shape of the detection box 1 is not particularly limited, and the detection box 1 can be configured to be cylindrical, square, or irregularly shaped, etc. The square detection box 1 will be taken as an example to specifically describe the air duct life detection device 100 .

[0039] An air inlet 11 may be formed on the side wall of the detection box 1. In one embodiment, an elastic and flexible pipe may be connected to the air inlet 11, or a pipeline structure may be formed by enclosing the convex wall structure of the detection box 1. By sleeved the pipe on the blowing port of the air duct 200, the hot air flow blown out by the air duct 200 can better enter the detection box 1.

[0040] Preferably, the air inlet 11 forms the air inlet channel, making the structure simpler. And when performing testing, it is convenient for the air outlet of the wind tube 200 to be connected to the air inlet 11, and the operation is also more convenient. The testing jig 2 is located on one side of the air inlet 11 and has a clamping portion suitable for clamping the wind tube 200, so that when the wind tube 200 is fixed on the testing jig 2, the air outlet of the wind tube 200 at least partially extends into the air inlet 11. The wind tube 200 is clamped and fixed to one side of the testing box 1 by the clamping portion, and the air flow blown out of the air outlet of the wind tube 200 can better enter the air inlet 11 to enter the testing box 1, and then the hot air flow is discharged from the testing environment through the suction device 3, so that the wind tube 200 is always in a stable working environment, and the testing environment is more consistent with the actual use environment. Therefore, the test result has more practical comparison value and is more accurate and reliable.

[0041] Since the hair dryer 200 generally includes a main body and a handle, both of which are roughly cylindrical, and their central axes are arranged nearly vertically, and the air outlet is provided on the main body, it is preferable that the hair dryer 200 can be clamped and fixed to the handle by the clamping portion during testing, so that the air outlet can be aligned with the air inlet 11 on the test box 1. Specifically, the clamping portion includes two clamping plates arranged in opposition, at least one of which is movably provided on the test box 1, so that the two clamping plates can be moved closer to or further away from each other, thereby adjusting the distance between the two clamping plates to facilitate clamping hair dryers 200 of different sizes, and having a wider range of applications.

[0042] Further, combined with Figure 3 and Figure 4 As shown,

[0043] The two clamping plates are configured as a first clamping plate 21 and a second clamping plate 22. The inspection jig 2 also includes a guide cylinder 25 provided on the first clamping plate 21, and a guide post 23 with one end movably sleeved within the guide cylinder 25. The other end of the guide post 23 is connected to the second clamping plate 22. The guide post 23 moves relative to the guide cylinder 25 in response to an external force to adjust the distance between the first clamping plate 21 and the second clamping plate 22. Furthermore, the guided movement of the guide cylinder 25 and the guide post 23 makes the second clamping plate 22 more stable and reliable during movement.

[0044] It is understood that the guide post 23 can be moved manually or by a drive mechanism. Preferably, a handle is provided on the side of the second clamping plate 22 facing away from the first clamping plate 21. During use, the operator can pull the handle to move the second clamping plate 22 and the guide post 23 together to adjust the distance between the two clamping plates.

[0045] Moreover, if Figure 4 As shown in FIG, the inspection jig 2 further includes an elastic member 24 connecting the first and second clamping plates 21 and 22. When the second clamping plate 22 is moved away from the first clamping plate 21 by an external force, the elastic member 24 is elastically deformed. When the external force on the second clamping plate 22 is removed, the second clamping plate 22 can move toward the first clamping plate 21 under the elastic restoring force of the elastic member 24. The elastic member 24 can be configured as a telescopic spring or an elastic rubber member. When the operator pulls the handle, the second clamping plate 22 moves away from the first clamping plate 21, increasing the distance between the second clamping plate 22 and the first clamping plate 21 to facilitate placement of the handle portion of the hair dryer 200. At this point, the elastic member 24 is in a stretched state. Once the hair dryer 200 is in place, the force exerted by pulling the handle can be reduced or removed, causing the second clamping plate 22 to gradually move toward the first clamping plate 21, thereby clamping the second clamping plate 22 and the first clamping plate 21 together on both sides of the handle portion of the hair dryer 200. Moreover, through this arrangement, when the air outlet of the hair dryer 200 is not completely aligned with the air inlet 11, the handle can be pulled with one hand and the hair dryer 200 can be rotated with the other hand, which makes the adjustment convenient and flexible and the operation labor-saving.

[0046] Combine Figure 4 As shown in the figure, the first clamping plate 21 is roughly arranged in a "T" shape, with a bottom plate and a side plate protruding from the middle of the bottom plate, and the bottom plate has a first end and a second end located on both sides of the side plate, and the first end is provided with a mounting hole for connecting with the detection box 1, and the second end is arranged close to the second clamping plate 22 for supporting one side of the wind tube 200, and the guide column 23 can extend from the second end.

[0047] It is understood that when the air inlet 11 is arranged horizontally, both clamping plates also extend horizontally, so that after clamping and fixing the air cylinder 200, the handle portion of the air cylinder 200 is placed horizontally, so that the air outlet can be better oriented towards the air inlet 11. If the air inlet 11 is arranged in a vertical direction, both clamping plates can be arranged in the vertical direction, so that after clamping and fixing the air cylinder 200, the handle portion of the air cylinder 200 is placed in the vertical direction, so that the air outlet can be better oriented towards the air inlet 11. The position and direction of the corresponding clamping plates can be appropriately adjusted according to the position and direction of different air inlet 11.

[0048] In one embodiment, combining Figure 1 and Figure 2As shown, there are multiple air inlets 11, which are arranged in an array on the upper surface of the test box 1; there are multiple sets of detection fixtures 2, which are arranged one-to-one with the multiple air inlets 11, so that multiple air ducts 200 can be tested simultaneously, improving detection efficiency. Of course, the specific number and layout of the multiple air inlets 11 and the multiple sets of detection fixtures 2 can be reasonably set according to the actual detection space.

[0049] Preferably, multiple air inlets 11 are provided on the upper surface of the detection box 1, wherein the upper surface of the detection box 1 is arranged in a stepped manner, having a first stepped surface at a higher position and a second stepped surface at a lower position; wherein each of the first stepped surface and the second stepped surface is provided with at least one row of the air inlets 11. By providing surfaces of different heights, there is sufficient space on the side of the stepped portion of the detection box 1 to install a power socket 42, thereby conveniently providing power to each air duct 200.

[0050] An air outlet 12 is provided on one side of the detection box 1. In one embodiment, an elastic and flexible pipe can be connected to the air outlet 12, or a pipe structure can be formed by enclosing the convex wall structure of the detection box 1. By connecting the suction device 3 with the pipe at the air outlet 12, the hot air flow in the detection box 1 can be extracted and discharged to a designated location, such as outdoors or a location that requires heating, thereby improving energy conversion and utilization.

[0051] Preferably, if Figure 2 As shown in FIG, two air outlets 12 are provided. The two air outlets 12 are arranged near the bottom of the detection box 1 and are located on the back of the detection box 1. The suction device 3 is arranged at the air outlet 12 and is located outside the detection box 1. The suction device 3 is configured as a fan or a vacuum pump. The suction device 3 operates to suck the hot air generated by the multiple air ducts 200 when they are in operation out of the detection box 1, thereby preventing the temperature of each air duct 200 from rising, maintaining a stable detection environment, and improving detection accuracy.

[0052] In addition, a plurality of rollers may be provided at the bottom of the detection box 1 , and a locking wheel member may be provided on each roller to facilitate the transfer of the air duct life detection device 100 .

[0053] The electric control device 4 can not only provide electric energy to each wind tube 200, but also be used to obtain the working data of each wind tube 200 when it is working. Figure 1As shown in the figure, the electric control device 4 includes an electric control box 41, a power socket 42, and a power detection mechanism 43; the power socket 42 is provided on the detection box 1 and is provided corresponding to the detection fixture 2. Preferably, the power socket 42 and the detection fixture 2 are located on different surfaces of the detection box 1; the power detection mechanism 43 is provided in the electric control box 41 and is electrically connected to the power socket 42, and is used to detect the current value and / or voltage value at the power socket 42. The working condition of the hair dryer 200 can be determined by the detected current value and / or voltage value, so as to accurately determine the service life of the hair dryer 200.

[0054] Furthermore, there are multiple power supply sockets 42; the multiple power supply sockets 42 are arranged in a one-to-one correspondence with the multiple detection fixtures 2, so that each hair dryer 200 can be detected independently, and during the detection, it is not necessary to place each detection fixture 2 on the hair dryer 200 before the detection can be carried out, and the number of detections is more independent and flexible.

[0055] Correspondingly, a plurality of power detection mechanisms 43 are provided, and the plurality of power detection mechanisms 43 are arranged in a one-to-one correspondence with the plurality of power sockets 42. By detecting the corresponding air ducts 200 through the power detection mechanisms 43, the working status of each air duct 200 can be better understood, and the detection accuracy is improved. The plurality of power detection mechanisms 43 are all integrated into the electrical control box 41, making management and maintenance more convenient.

[0056] A display screen may be provided on the outside of the electric control box 41, and the display screen may be electrically connected to a plurality of power detection mechanisms 43. The detection status may be observed in real time through the display screen, so that the working condition of each air duct 200 during the detection process may be understood in real time and abnormalities may be discovered in time.

[0057] Moreover, a power control switch can be provided at each power socket 42, and the power on and off of the corresponding power socket 42 can be controlled by the power control switch, so that there is no need to repeatedly plug and unplug the plug of the hair dryer 200, and the power on and off of the hair dryer 200 is more convenient.
