Description

Technical Field

[0001] The invention relates to the technical field of hair dryer testing, in particular to a hair dryer performance testing device. Background Art

[0002] Hair dryers mainly use electric motors to drive fan blades to rotate, form airflow, and use electric heating elements to heat air, so as to quickly dry hair or other items. They usually have multiple wind speed and temperature settings to meet the needs of different users. As a commonly used electrical product in daily life, the reliability of hair dryers is directly related to the user experience and safety. Therefore, it is very important to test hair dryers.

[0003] However, the current testing methods mostly still rely on manual operation, mostly by manually holding a hair dryer and placing it at a preset position to test the wind force detector. The test range is single, and the test efficiency is low. In addition, workers are prone to fatigue during long-term testing, and operational errors are prone to occur, resulting in errors in the test results.

[0004] Or, as disclosed in the publication number "CN118168611B", a hair dryer testing device is provided. In this patented technology, the airflow blown out by the hair dryer enters the testing cylinder. When the airflow enters the testing cylinder, the wind measuring unit in the wind measuring box outside the testing cylinder detects the wind force entering, and the reader reads the value detected by the wind measuring box to detect the wind force. The two temperature measuring units in the temperature measuring box detect the temperature of the wind force blown out by the hair dryer to detect the wind temperature.

[0005] However, since the hair dryer is provided with different gears, the wind force at different gears needs to be detected during the test.

[0040] When testing, the hair dryer body 7 to be tested is first placed on the fixing assembly 3, and the air outlet of the hair dryer body 7 is clamped on the sealing cylinder 22. The sealing ring provided in the sealing cylinder 22 further increases the sealing between the hair dryer body 7 and the sealing cylinder 22, and the gear adjustment assembly 4 is started to make the hair dryer body 7 start running;

[0041] When the hair dryer body 7 is running, the wind force generated by the hair dryer body 7 pushes the temperature measuring plate 61 to slide along the limit slide groove 26 in the wind measuring cylinder 21, and the wind speed of the hair dryer body 7 is calculated by analyzing the sliding speed of the temperature measuring plate 61 through the speed sensor provided in the limit slide groove 26;

[0043] When the test is completed, start the drive motor 65, so that the drive motor 65 drives the rope collection drum 64 to rotate through the third connecting shaft 66, and at the same time drives the other rope collection drum 64 to rotate through the second synchronous belt 67. The connecting rope 63 is retracted through the rotation of the two rope collection drums 64, so that the connecting rope 63 pulls the temperature measuring disk 61 to reset, which is convenient for subsequent testing work.

[0044] In this embodiment, the fixing assembly 3 includes a fixing frame 31, which is fixedly connected to the mounting plate 11. A placement groove 32 having the same diameter as the wind tube of the hair dryer body 7 is provided on the top of the fixing frame 31. The hair dryer body 7 is placed on the placement groove 32. Electric push rods 33 are also installed on the inner walls on both sides of the fixing frame 31. The output ends of the two electric push rods 33 are fixedly connected to clamping rings 34. The arc surfaces of the two clamping rings 34 are in contact with the hair dryer body 7.

[0045] When fixing the hair dryer body 7, first place the hair dryer body 7 on the fixing frame 31 so that the bottom of the hair dryer body 7 is located between the two clamping rings 34. After the air outlet end of the hair dryer body 7 is clamped on the sealing tube 22, start the two electric push rods 33 so that the two electric push rods 33 drive the clamping rings 34 to move towards the direction close to the hair dryer body 7, so that the two clamping rings 34 are respectively in contact with the hair dryer body 7, and the hair dryer body 7 can be fixed.

[0046] In this embodiment, the gear adjustment component 4 includes a driving shaft 41, which is rotatably connected to a plurality of fixed frames 31 on the same side, one end of the driving shaft 41 passes through the sealing plate 12 and extends to the outside of the sealing plate 12, and a servo motor is fixedly connected to the extended end of the driving shaft 41, and a plurality of driving gears 43 are fixedly connected to the driving shaft 41, and the plurality of driving gears 43 are respectively rotatably connected to adjacent fixed frames 31, and a fixing rod 42 is also provided on one side of the driving shaft 41, and the fixing rod 42 is fixedly connected to the plurality of fixed frames 31, and a plurality of driven gears 44 with the same position as the driving gear 43 are rotatably connected to the fixing rod 42, and the plurality of driven gears 43 are respectively rotatably connected to the adjacent fixed frames 31. 4 are respectively meshed with the adjacent driving gears 43, one side of the driven gear 44 is also fixedly connected with a synchronous rotating disk 45, the synchronous rotating disk 45 is rotatably connected to the fixed rod 42, the side of the synchronous rotating disk 45 away from the driven gear 44 is fixedly connected with a connecting plate 46, both ends of the connecting plate 46 are respectively hinged with pressing plates 47, one end of the two pressing plates 47 away from the connecting plate 46 penetrates the inner wall of the adjacent fixing frame 31 and extends to the outside of the fixing frame 31, one side of the driving gear 43 is also fixedly connected with a first connecting shaft 48, the first connecting shaft 48 is provided with a first synchronous belt 49, and the other end of the first synchronous belt 49 is connected to the temperature adjustment component 5;

[0047] When testing, the servo motor on one side of the test bench 1 is started, so that the output end of the servo motor drives the driving shaft 41 to rotate. When the driving shaft 41 rotates, the driving gear 43 is driven to rotate at the same time. The driving gear 43 drives the synchronous turntable 45 to rotate through the driven gear 44. When the synchronous turntable 45 rotates, the connecting plate 46 provided on the synchronous turntable 45 rotates synchronously. Under the pull of the connecting plate 46, one of the pressing plates 47 is extended outward and the other pressing plate 47 is retracted inward. The pressing plate 47 extended outward squeezes the wind speed adjustment button 71, so that the hair dryer body 7 is started and the test is carried out.

[0048] When one gear test is completed, the servo motor is started again to repeat the above work and change the gear. After all tests are completed, the servo motor is driven to reverse, so that the connecting plate 46 drives the two pressing plates 47 to move in the opposite direction, so that the originally retracted pressing plate 47 extends outward to press the wind speed adjustment button 71 to close the hair dryer body 7.

[0049] In this embodiment, the temperature adjustment component 5 includes a second connecting shaft 51, which is connected to the first connecting shaft 48 through a first synchronous belt 49, and the second connecting shaft 51 is rotatably connected to the fixed frame 31. One side of the second connecting shaft 51 is fixedly connected to the first bevel gear 52 through a connecting rod, and the first bevel gear 52 is meshed with a second bevel gear 53, and the second bevel gear 53 is rotatably connected to the fixed frame 31. A fixed cylinder 54 is also installed in the fixed frame 31, and a synchronous shaft 56 is rotatably connected in the fixed cylinder 54, and one end of the synchronous shaft 56 close to the second bevel gear 53 is fixed to the second bevel gear 53, and a single A synchronous sleeve 57 is also slidably arranged in the fixed cylinder 54, and a pressing rod 55 is fixedly connected to the side of the synchronous sleeve 57 away from the synchronous shaft 56, and the pressing rod 55 passes through one side of the fixed cylinder 54 and extends to the outside of the fixed cylinder 54, and a return spring is also installed on the side of the synchronous sleeve 57 away from the pressing rod 55, and one end of the return spring is fixed to the synchronous sleeve 57, and the other end is fixed to the end of the fixed cylinder 54 close to the second bevel gear 53, and two spiral slideways 58 are centrally symmetrically installed on the outer surface of the synchronous shaft 56, and two pins 59 with the same position as the spiral slideways 58 are installed in the inner wall of the synchronous sleeve 57, and the two pins 59 are respectively located below the adjacent spiral slideways 58;

[0050] When the driving shaft 41 and the driving gear 43 rotate, the driving gear 43 drives the second connecting shaft 51 to rotate through the first connecting shaft 48 and the first synchronous belt 49 at the same time. When the second connecting shaft 51 rotates, the second bevel gear 53 is driven to rotate through the first bevel gear 52 at the same time, so that the synchronous shaft 56 rotates in the fixed cylinder 54. When the synchronous shaft 56 rotates, the pin 59 in the synchronous sleeve 57 moves downward under the push of the spiral slide 58, so that the synchronous sleeve 57 and the pressing rod 55 are simultaneously contracted toward the fixed cylinder 54, and the reset spring is compressed and contracted to accumulate force. When the hair dryer body 7 is tested at a temperature, the spiral slide 58 drives the two pins 59 to move to the bottom of the spiral slide 58 at the same time. When the servo motor on the gear adjustment assembly 4 reverses to drive the hair dryer body 7 to close, the one-way bearing arranged between the second bevel gear 53 and the synchronous shaft 56 prevents the second bevel gear 53 from driving the synchronous shaft 56 to reverse, and the synchronous shaft 56 remains stationary.

[0051] When the gear adjustment assembly 4 starts to adjust the gear again, the second bevel gear 53 drives the synchronization shaft 56 to rotate slightly, so that the spiral slide 58 is separated from the pin 59. After separation, under the action of the return spring, the synchronization sleeve 57 drives the pressing rod 55 to pop outward, so that the pressing rod 55 squeezes the temperature adjustment button 72 to adjust the air outlet temperature of the hair dryer body 7;

[0052] At the same time, when the pin 59 moves outward following the synchronization sleeve 57, since the pin 59 is below the spiral slide 58 in the initial position, when the synchronization shaft 56 drives the spiral slide 58 to rotate, the pin 59 will still be rotated to the bottom of the spiral slide 58 for reciprocating motion.

[0053] The working principle of the present invention is as follows: when testing, the hair dryer body 7 is first placed on the fixing frame 31, so that the bottom of the hair dryer body 7 is located between the two clamping rings 34, and after the air outlet end of the hair dryer body 7 is clamped on the sealing cylinder 22, the two electric push rods 33 are started, so that the two electric push rods 33 drive the clamping rings 34 to move toward the direction close to the hair dryer body 7, so that the two clamping rings 34 fix the hair dryer body 7;

[0054] Start the servo motor on one side of the test bench 1, so that the output end of the servo motor drives the driving shaft 41 to rotate. When the driving shaft 41 rotates, it drives the driving gear 43 to rotate at the same time. The driving gear 43 drives the synchronous turntable 45 to rotate through the driven gear 44. When the synchronous turntable 45 rotates, the connecting plate 46 provided on the synchronous turntable 45 rotates synchronously. Under the pull of the connecting plate 46, one of the pressing plates 47 extends outward and the other pressing plate 47 retracts inward. The pressing plate 47 extending outward squeezes the wind speed adjustment button 71, so that the hair dryer body 7 is started and the test is carried out.

[0055] When one gear test is completed, the servo motor is started again to repeat the above work to change the gear. After all tests are completed, the servo motor is driven to reverse, so that the connecting plate 46 drives the two pressing plates 47 to move in the opposite direction, so that the originally retracted pressing plates 47 extend outward to press the wind speed adjustment button 71 to close the hair dryer body 7;

[0056] When the driving shaft 41 and the driving gear 43 rotate, the driving gear 43 drives the second connecting shaft 51 to rotate through the first connecting shaft 48 and the first synchronous belt 49 at the same time. When the second connecting shaft 51 rotates, the second bevel gear 53 is driven to rotate through the first bevel gear 52 at the same time, so that the synchronous shaft 56 rotates in the fixed cylinder 54. When the synchronous shaft 56 rotates, the pin 59 in the synchronous sleeve 57 moves downward under the push of the spiral slide 58, so that the synchronous sleeve 57 and the pressing rod 55 are simultaneously contracted toward the fixed cylinder 54, and the reset spring is compressed and contracted to accumulate force. When the hair dryer body 7 is tested at a temperature, the spiral slide 58 drives the two pins 59 to move to the bottom of the spiral slide 58 at the same time. When the servo motor on the gear adjustment assembly 4 reverses to drive the hair dryer body 7 to close, the one-way bearing arranged between the second bevel gear 53 and the synchronous shaft 56 prevents the second bevel gear 53 from driving the synchronous shaft 56 to reverse, and the synchronous shaft 56 remains stationary.

[0057] When the gear adjustment assembly 4 starts to adjust the gear again, the second bevel gear 53 drives the synchronization shaft 56 to rotate slightly, so that the spiral slide 58 is separated from the pin 59. After separation, under the action of the return spring, the synchronization sleeve 57 drives the pressing rod 55 to pop outward, so that the pressing rod 55 squeezes the temperature adjustment button 72 to adjust the air outlet temperature of the hair dryer body 7;

[0058] When the hair dryer body 7 is running, the wind force generated by the hair dryer body 7 pushes the temperature measuring plate 61 to slide along the limit slide groove 26 in the wind measuring cylinder 21, and the wind speed of the hair dryer body 7 is calculated by analyzing the sliding speed of the temperature measuring plate 61 through the speed sensor provided in the limit slide groove 26;

[0059] When the temperature measuring disk 61 slides, the wind temperature at different positions is collected at the same time. The wind speed and wind temperature are integrated and transmitted to the processor 23 through the signal line 62. After being analyzed by the processor 23, they are displayed on the display 24.

[0060] It should be noted that any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
