[0045] Referring to Figures 1-6 , the utility model embodiment proposes a handheld vacuum cleaner testing device, including testing platform 1, LED lamp detection module 2, display screen detection module 3 and negative pressure suction force detection module 4.

[0046] The test platform 1 can support the handheld vacuum cleaner 5. The LED lamp detection module 2 and the display screen detection module 3 are both arranged on the test platform 1. The LED lamp detection module 2 can detect the illumination of the LED lamp 511 on the handheld vacuum cleaner 5 in the on state, and the display screen detection module 3 can detect whether the first display screen 521 on the handheld vacuum cleaner 5 in the on state is lit and the brightness. The negative pressure suction detection module 4 is located on one side of the test platform 1 and can be inserted into the air inlet 531 of the handheld vacuum cleaner 5 to detect the negative pressure suction of the handheld vacuum cleaner 5 in the on state.

[0047] In use, after the handheld vacuum cleaner 5 is supported on the test platform 1, the illumination of the LED lamp 511 on the handheld vacuum cleaner 5 is detected by the LED lamp detection module 2, whether the first display screen 521 on the handheld vacuum cleaner 5 is lit and the brightness are detected by the display screen detection module 3, and the negative pressure suction is detected by the negative pressure suction detection module 3 inserted into and closed in the air inlet 531 of the handheld vacuum cleaner 5, so as to simultaneously detect the illumination of the LED lamp 511, whether the first display screen 521 is lit and the brightness, and the negative pressure suction of the handheld vacuum cleaner 5 in the on state, so as to improve the test efficiency of the handheld vacuum cleaner 5 and further improve the production efficiency. At the same time, the LED lamp detection module 2 and the display screen detection module 3 are integrated on the test platform 1, and the negative pressure suction detection module 4 is arranged on one side of the test platform 1, so as to reduce the overall volume of the test device and facilitate placement on the production line with limited space.

[0048] Further, in order to realize the alignment detection of the handheld vacuum cleaner 5, the test platform 1 can also limit the translational degrees of freedom of the handheld vacuum cleaner 5 supported on the test platform 1 in the x-axis, y-axis and z-axis, and the rotational degrees of freedom of the handheld vacuum cleaner 5 around its own axis, so as to limit the handheld vacuum cleaner 5 on the test platform 1, and make the LED lamp 511, the first display screen 521 and the air inlet 531 on the handheld vacuum cleaner 5 correspond to the LED lamp detection module 2, the display screen detection module 3 and the negative pressure suction detection module 4 one by one, so as to facilitate alignment detection and improve detection accuracy and detection efficiency.

[0049] The axis of the handheld vacuum cleaner 5 refers to the axis of the dust collecting box 51 of the handheld vacuum cleaner 5.

[0050] Specifically, the test platform 1 includes a horizontally oriented base 11, and a first support plate 12 and a second support plate 13 vertically fixed on the top of the base 11. The first support plate 12 and the second support plate 13 are perpendicular to each other.

[0051] The base 11, the first support plate 12 and the second support plate 13 form a space for supporting the axially vertical dust collecting box 51 in the handheld vacuum cleaner 5, and limit the translational degrees of freedom of the dust collecting box 51 in the x-axis, the y-axis and the z-axis. The limiting block 14 capable of abutting against one side of the vertically oriented handheld part 52 in the handheld vacuum cleaner 5 is arranged on the first support plate 12 or the second support plate 13, so as to limit the rotational degree of freedom of the handheld part 52 around the axis of the dust collecting box 51.

[0052] In use, the dust collecting box 51 of the handheld vacuum cleaner 5 is first placed on the base 11 in an axially vertical state and abuts against the side walls of the first support plate 12 and the second support plate 13, so as to limit the translational degrees of freedom of the dust collecting box 51 in the x-axis, the y-axis and the z-axis. Then, the handheld vacuum cleaner 5 is rotated to the side of the vertically oriented handheld part 52 abutting against the limiting block 14, so as to limit the rotational degree of freedom of the handheld part 52 around the axis of the dust collecting box 51.

[0053] Further, the LED lamp detection module 2 is arranged on the first support plate 12, and the detection end of the LED lamp detection module 2 is arranged downward, so as to face and support the LED lamp 511 on the upper end of the dust collecting box 51 on the base 11, the first support plate 12 and the second support plate 13, and detect the illumination of the LED lamp 511.

[0054] The display screen detection module 3 is arranged on the second support plate 13, and the detection end of the display screen detection module 3 is horizontally oriented, so as to face the first display screen 521 on the handheld part 52 which is vertically oriented and has one side abutting against the limiting block 14, and detect whether the first display screen 521 is lit and the brightness.

[0055] Preferably, the LED lamp detection module 2 and the display screen detection module 3 are both photoelectric sensors.

[0056] Specifically, the first support plate 12 is fixedly connected with a fixed box 16, and the fixed box 16 contains the LED lamp detection module 2. The bottom of the fixed box 16 is provided with a window 161 capable of exposing the detection end of the LED lamp detection module 2, so that the detection end of the LED lamp detection module 2 is arranged downward.

[0057] The second support plate 13 is fixedly provided with a fixed block 17, and the display screen detection module 3 is fixedly connected to the fixed block 17.

[0058] Therefore, the LED lamp detection module 2 and the display screen detection module 3 are integrated on the test platform 1, so as to reduce the overall volume of the test device.

[0059] Further, the negative pressure suction force detection module 4 comprises a negative pressure detector 41, a first air pipe 42 and a test head 43.

[0060] Two ends of the first air pipe 42 are connected with the negative pressure detector 41 and the test head 43 respectively. Two ends of the test head 43 are through, for inserting into the suction port 531 of the suction cylinder 53 and closing the suction port 531. The suction cylinder 53, the test head 43 and the first air pipe 42 are communicated to form a negative pressure passage.

[0061] In use, the test head 43 is inserted into the suction port 531 of the suction cylinder 53 of the handheld vacuum cleaner 5 supported on the test platform 1, and then the handheld vacuum cleaner 5 is turned on. The suction cylinder 53 inhales the first air pipe 42 through the test head 43, and the negative pressure of the suction cylinder 53 is detected by the negative pressure detector 41.

[0062] Specifically, the negative pressure detector 41 comprises a negative pressure sensor for detecting the negative pressure of the handheld vacuum cleaner 5.

[0063] Further, the detection principle of the handheld vacuum cleaner testing device is as follows:

[0064] S1: First, place the dust collecting box 51 of the handheld vacuum cleaner 5 in an axial vertical state on the base 11 and abut against the side walls of the first support plate 12 and the second support plate 13, and then rotate the handheld vacuum cleaner 5 to make one side of the handheld part 52 abut against the limiting block 14. In this way, the LED lamp detection module 2 can be directed to the LED lamp 511 at the upper end of the axial vertical dust collecting box 51, and the display screen detection module 3 can be directed to the first display screen 521 on the vertically oriented handheld part 52, which is convenient to operate and ensures the alignment accuracy.

[0065] S2: Insert the test head 43 into the suction port 531 of the suction cylinder 53 of the handheld vacuum cleaner 5 supported on the test platform 1.

[0066] S3: Turn on the handheld vacuum cleaner 5, obtain the illumination of the LED lamp 511 through the LED lamp detection module 2, obtain whether the first display screen 521 is lit and the brightness through the display screen detection module 3, and inhale the first air pipe 42 through the test head 43 by the suction cylinder 53, so as to obtain the negative pressure of the suction cylinder 53 through the negative pressure detector 41.

[0067] Therefore, the handheld vacuum cleaner testing device can conveniently realize the alignment detection of the LED lamp 511, the display screen 521 and the negative pressure of the handheld vacuum cleaner 5 in the on state by the LED lamp detection module 2, the display screen detection module 3 and the negative pressure detection module 4 one by one, which ensures the detection accuracy and improves the detection efficiency.

[0068] As can be seen from the above, the detection process in the handheld vacuum cleaner testing device utilizes the conventional performance of conventional instruments including photoelectric sensors and negative pressure sensors, and there is no analysis and control process in the detection process.

[0069] Specifically, the test head 43 comprises a test head body 431.

[0070] The test head body 431 is an elongated plate body, which is adapted to the internal shape of the suction cylinder 53 for easy insertion. The thickness of the test head body 431 gradually decreases from the first end to the second end in the length direction, and the two ends are through. The second end of the test head body 431 can be inserted into the suction port 531, and the peripheral wall of the first end of the test head body 431 can abut against the inner wall of the suction cylinder 53 to be clamped in the suction cylinder 53, so that the test head body 431 is not sucked into the suction cylinder 53 as a whole, and the suction port 531 can be sealed to improve the detection accuracy.

[0071] Preferably, the two sides of the first end of the test head body 431 protrude to form inclined blocks 432 in the thickness direction. The inclined blocks 432 extend along the length direction of the test head body 431, and the thickness of the inclined blocks 432 gradually decreases from the first end to the second end of the test head body 431. The longitudinal section of the inclined blocks 432 is triangular.

[0072] When the second end of the test head body 431 is inserted into the suction port 531, the inclined surface of the inclined blocks 432 can abut against the end of the suction port 531 to further improve the clamping force with the suction cylinder 53, so that the test head body 431 is not sucked into the suction cylinder 53 as a whole.

[0073] Specifically, in order to facilitate the connection of the test head body 431 and the first air pipe 42, the test head 43 further comprises an end cover 434 sealingly connected to the first end of the test head body 431.

[0074] The end cover 434 and the test head body 431 are in communication. The first air pipe joint 435 is arranged on the end cover 434, and the first air pipe joint 435 is connected to the first air pipe 42. The suction port 531 of the suction cylinder 53, the test head body 431, the end cover 434 and the first air pipe 42 are in communication to form a negative pressure passage.

[0075] During testing, the suction cylinder 53 can sequentially inhale air through the test head body 431 and the end cover 434 to the first air pipe 42.

[0076] More specifically, in order to facilitate the connection of the test head body 431 and the end cover 434: the first end of the test head body 431 extends outward along the length direction to form a cylindrical connecting head 433. The two ends of the connecting head 433 are through.

[0077] The end cover 434 is a cylinder body with two through ends. The end cover 434 can be sleeved outside the connecting head 433, and the gap between the end cover 434 and the connecting head 433 is filled with sealant to seal the gap between the end cover 434 and the connecting head 433, so as to avoid air leakage and improve the negative pressure detection accuracy. The test head body 431, the connecting head 433 and the end cover 434 are in communication in sequence.

[0078] When testing, the suction tube 53 can sequentially pass through the test head main body 431, the connecting head 433 and the end cover 434 to inhale air from the first air pipe 42.

[0079] Further, the negative pressure suction force detection module 4 further comprises a box body 44, which is located on one side of the test platform 1, and the negative pressure detector 41 is arranged on the box body 44.

The side wall of the box body 44 is further provided with a switch 446 for controlling the opening and closing of the power supply 47.

[0083] When testing, the handheld vacuum cleaner 5 is first supported and positioned on the test platform 1, the switch 446 is turned on to turn on the power supply 47, and at the same time, the power supply switch of the handheld vacuum cleaner 5 is turned on. The LED lamp detection module 2, the display screen detection module 3 and the negative pressure detector 41 are turned on and detect the illumination of the LED lamp 511, whether the first display screen 521 is lit and the brightness, and the negative pressure of the handheld vacuum cleaner 5 in the turned-on state.
