[0002] A vacuum cleaner suction power tester is a device specifically designed to evaluate the performance of vacuum cleaners. It uses sensors, control systems, and data processing software to test and analyze the suction power of vacuum cleaners, thereby providing detailed test data.

[0003] Vacuum cleaners are used in a variety of scenarios, including wood floors, tiles, and carpets. However, the surface roughness, density, and structure of wood floors, tiles, and carpets are different, which means that the suction power generated by the vacuum cleaner with the same suction mode will be different on wood floors, tiles, and carpets. However, existing suction power testing machines only test the suction power of the vacuum cleaner itself, which makes it difficult to simulate and change the actual usage scenarios. This results in the test data provided by the suction power testing machine being different from the actual usage situation.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example: Vacuum cleaner suction power testing machine, such as Figures 1-4 As shown, the device includes a suction tester body 1, which comprises a housing 2, a gas flow meter 3, a negative pressure sensor 4, and an industrial control computer 5. The housing 2 is made of stainless steel, and the high strength of stainless steel allows the housing 2 to withstand greater pressure and is not easily deformed. The industrial control computer 5 is fixedly connected to the outer wall on one side of the width of the housing 2. An annular placement groove 16 is provided on the top surface of the housing 2. An annular sealing ring 17 is fixedly connected to the bottom of the placement groove 16. The thickness of the sealing ring 17 is less than the depth of the placement groove 16, and the cross-sectional shape of the sealing ring 17 is the same as that of the placement groove 16. An air outlet 18 is provided through the center of the placement groove 16 on the top surface of the housing 2. The gas flow meter 3 is fixedly connected to the inner top surface of the housing 2, and the gas flow meter 3 is connected to the air outlet 18.

[0022] like Figures 1-4 As shown, a circular through hole 19 is provided on one side of the width of the housing 2. The negative pressure sensor 4 is connected to the industrial control computer 5 via a wire. The diameter of the negative pressure sensor 4 is the same as the diameter of the through hole 19. The negative pressure sensor 4 passes through the through hole 19 into the housing 2. Both the gas flow meter 3 and the industrial control computer 5 are equipped with Bluetooth modules, enabling the gas flow meter 3 to connect with the industrial control computer 5 via Bluetooth. When the air inlet pipe of the vacuum cleaner abuts against the sealing ring 17, it is connected to the air outlet 18. When the vacuum cleaner is started, it can generate negative pressure by sucking gas from the housing 2. The negative pressure value generated by the vacuum cleaner can be measured by the negative pressure sensor 4, and the volume of air flowing into the vacuum cleaner per unit time can be measured by the gas flow meter 3. The values ​​measured by the negative pressure sensor 4 and the gas flow meter 3 are sent to the industrial control computer 5. After analyzing the measured values, the industrial control computer 5 can determine the suction power generated by the vacuum cleaner. When negative pressure is generated in the housing 2, it can drive the air inlet pipe of the vacuum cleaner to abut tightly against the sealing ring 17, ensuring the sealing effect.

[0023] like Figures 1-3As shown, the shell 2 is hollow inside. A groove 6 communicating with the inner cavity is opened at the bottom of the shell 2. The cross-section of the groove 6 is rectangular. The side of the groove 6 near the through groove 10 passes through the side wall of the shell 2. The groove 6 is provided with any one base plate 7, one base plate 8, and one base plate 9. The length, width, and thickness of the base plate 7, the base plate 8, and the base plate 9 are the same as the length, width, and depth of the groove 6, respectively. Two symmetrically arranged handles 15 are fixedly connected to the side of the base plate 7, the base plate 8, and the base plate 9 away from the shell 2. By pulling the two handles 15 at the same time, any one base plate 7, the base plate 8, or the base plate 9 can be detachably connected to the groove 6.

[0024] like Figures 1-3 As shown, the side of the slide groove 6 furthest from the through groove 10 is recessed into the inner wall of the length side of the housing 2, and the two sides of the width of the slide groove 6 are respectively recessed into the inner walls of the two sides of the width of the housing 2. When the end of any one of the base plates 7, 8, or 9 furthest from the handle 15 moves to abut against the side of the slide groove 6, the peripheral wall of any one of the base plates 7, 8, or 9 abuts against the inner wall of the through groove 10, thereby engaging in the through groove 10. A rectangular through groove 10 communicating with the slide groove 6 is provided on the length side of the housing 2. The length of the through groove 10 is the same as the length of the inner cavity of the housing 2. The through groove 10 is located above the slide groove 6. Any wooden floor 11, tile 12, or blanket 13 can be detachably connected in the through groove 10. The wooden floor 11, tile 12, and blanket 13 are respectively fixedly connected to the base plates 7, 8, and 9.

[0025] like Figures 1-3 As shown, the length and thickness of the wood flooring 11, tile 12, and blanket 13 are the same as the length and depth of the through groove 10, respectively. The distance between the width of the through groove 10 and the width of the inner cavity of the housing 2 is the same as the width of any one of the wood flooring 11, tile 12, or blanket 13. The wood flooring 11 and the side of the base plate 11 near the handle 15 are on the same horizontal plane. The tile 12 and the side of the base plate 2 near the handle 15 are on the same horizontal plane. The blanket 13 and the side of the base plate 3 near the handle 15 are on the same horizontal plane. When the base plate 11 is engaged in the slide groove 6, the wood flooring 11 is placed at the bottom of the housing 2. When the base plate 2 is engaged in the slide groove 6, the tile 12 is placed at the bottom of the housing 2. At the bottom of the housing 2, when the bottom plate 3 9 is engaged in the sliding groove 6, the blanket 13 is placed at the bottom of the housing 2, so that the suction tester body 1 can simulate and change any test scenario of wood flooring 11, tile 12, or blanket 13. This allows the suction tester body 1 to test the suction power of the vacuum cleaner under different usage scenarios. Both sides of the width of the housing 2 are provided with long strip-shaped air inlet slots 14. Several air inlet slots 14 are symmetrically arranged 5mm above the through groove 10, thereby simulating the distance of the bottom of the vacuum cleaner's floor brush from the ground. This makes the suction power test of the vacuum cleaner by the suction tester body 1 more consistent with actual usage conditions, which helps manufacturers improve product design.

[0026] Working principle: After the vacuum cleaner's air inlet pipe is pressed against the sealing ring 17, the vacuum cleaner is started. The suction force generated by the vacuum cleaner draws in the gas inside the housing 2, creating a negative pressure inside the housing 2. The negative pressure value generated by the vacuum cleaner can be measured by the negative pressure sensor 4, and the air flow meter 3 can be measured by the volume of air flowing into the vacuum cleaner per unit time. The negative pressure sensor 4 and the air flow meter 3 send the measured values ​​to the industrial control computer 5. After the industrial control computer 5 analyzes the measured values, the suction force generated by the vacuum cleaner can be obtained. After the base plate 1 7 is snapped into the slide 6, the bottom of the inner cavity is made of wood flooring 11, so the suction force generated by the vacuum cleaner on the wood flooring 11 can be tested. After the base plate 2 8 is snapped into the slide 6, the bottom of the inner cavity is made of ceramic tile 12, so the suction force generated by the vacuum cleaner on ceramic tile 12 can be tested. After the base plate 3 9 is snapped into the slide 6, the bottom of the inner cavity is made of blanket 13, so the suction force generated by the vacuum cleaner on blanket 13 can be tested.
