[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example: Drop resistance testing equipment for vacuum cleaner floor brushes, such as... Figure 1 and Figure 2 As shown, the device includes a main body 1, which includes a testing housing 2 and a support 3. Two bearings 4 are symmetrically arranged on the top surface of the support 3. The outer peripheral wall of the bearing 4 is fixed to the support 3, and a rotating shaft 5 is fixedly connected to the inner peripheral wall of the bearing 4. The diameter of the rotating shaft 5 is the same as the inner diameter of the bearing 4, so that the rotating shaft 5 can be rotatably connected to the support 3 through the bearing 4. A test chamber 6 is provided between the two rotating shafts 5. The test chamber 6 includes a guide part 7 and two impact parts 8. The two sides of the guide part 7 are fixedly connected to the two ends of the rotating shafts 5 that are close to each other. The rotation axes of the guide part 7, the rotating shafts 5, and the bearings 4 are on the same straight line, so that the guide part 7 can rotate on the support 3 through the rotating shafts 5 and the bearings 4.

[0021] like Figure 2 and Figure 3 As shown, four symmetrically arranged screws 11 are fixedly connected to the outer walls at both ends of the guide part 7. Four rectangular grooves 12 are symmetrically opened on the peripheral wall of the impact part 8. The length of the screw 11 is greater than the depth of the groove 12. The screw 11 and the groove 12 are arranged correspondingly, so that the end of the screw 11 away from the guide part 7 passes through the groove 12, allowing the screw 11 to move back and forth in the groove 12. The inner wall of the impact part 8 abuts against the outer wall of the guide part 7, allowing the impact part 8 to move back and forth on the guide part 7. A nut 13 is threadedly connected to the end of the screw 11 that passes through the groove 12. By tightening the nut 13 on the screw 11, the guide part 7 and the impact part 8 can be fixed.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, both the guide section 7 and the impact section 8 are hollow inside, allowing the interior of the guide section 7 to communicate with the interiors of the two impact sections 8. A rectangular placement groove 14 is provided at the end of the impact section 8 away from the guide section 7. A through groove 15 is provided on the same side of the impact section 8 at the placement groove 14. A door 16 for opening and closing the through groove 15 is rotatably connected to the impact section 8. A limiting rod 18 is rotatably connected to both sides of the impact section 8 at the door 16. A rubber layer is fixedly connected to the side of the limiting rod 18 near the impact section 8. The rubber layer has good anti-slip and elasticity. When the limiting rod 18 is rotated until the rubber layer abuts against the door 16, it can generate a large friction force, thereby restricting the rotation of the door 16. When the limiting rod 18 is rotated until it is disengaged from the door 16, the through groove 15 can be opened. At this time, the floor brush to be tested can be placed into the test chamber 6.

[0023] like Figure 1 and Figure 2As shown, the testing housing 2 has a through hole 17 near the support 3 for the rotating shaft 5 to pass through. The testing housing 2 contains a drive motor and a controller. The end of the rotating shaft 5 that passes through the through hole 17 is fixedly connected to the drive motor. This drive motor is a servo motor, capable of high-precision and high-repeatability position, speed, and torque control. When the drive motor rotates, it drives the test chamber 6 to rotate. The bearing 4 reduces the force required to rotate the test chamber 6, thereby reducing the energy consumption of the drive motor. The floor brush located inside the test chamber 6 rotates with the test chamber 6 to move from the bottom to the top, and is subject to its own... The brush falls back to the bottom of the test chamber 6 due to gravity, thus repeatedly simulating the brush falling. The frequency of the brush fall test can be adjusted by controlling the speed of the drive motor. Both the bracket 3 and the test chamber 6 are made of aluminum alloy. The lightweight and high strength of aluminum alloy can ensure the structural strength of the bracket 3 and the test chamber 6. The cross-section of the bracket 3 is an isosceles trapezoid, which can maintain good stability when the test chamber 6 rotates. The outer wall of the test chamber is equipped with a control panel 19. The drive motor is electrically connected to the control panel 19 through the controller. The operating parameters of the drive motor can be adjusted and the drive motor can be started, stopped or stopped urgently through the control panel 19.

[0024] like Figures 1-4 As shown, a simulation plate 9 is snapped into the placement slot 14. A piece of wood flooring, tile, or carpet is fixedly connected to the side of the simulation plate 9 near the guide section 7. After any simulation plate 9 with wood flooring, tile, or carpet is selected and snapped into the placement slot 14, the falling floor brush will impact the wood flooring, tile, or carpet, thus simulating the impact of the floor brush falling onto different materials for simulation testing. A guide strip 10 is fixedly connected to the inner wall at both ends of the guide section 7. The guide strip 10 is made of rubber and has a fan-shaped cross-section. When the floor brush touches the guide strip 10 during the drop, the arc surface of the guide strip 10 can change the impact angle of the floor brush after the drop, thereby conducting impact tests on multiple surfaces of the floor brush. After the sliding impact part 8 is fixed by the screw 11 and nut 13, the length of the test chamber 6 can be adjusted, thereby simulating the situation after the floor brush is dropped and impacted at different heights. This makes the drop resistance test of the floor brush more comprehensive and more in line with actual use. A standardized and efficient test plan can be formulated according to different floor brush designs, and corresponding quality control requirements can be formulated to ensure the quality of the floor brush.

[0025] Working principle: To simulate the impact of a floor brush on different materials, a suitable simulation plate 9 is selected and inserted into the placement slot 14. After rotating the limiting rod 18 until it disengages from the door 16, the door 16 can be rotated to open and insert the floor brush. After rotating the limiting rod 18 until the door 16 abuts, the door 16 is closed, restricting its rotation. The drive motor is started via the control panel 19. When the drive motor rotates, it drives the test chamber 6 to rotate via the rotating shaft 5 and bearing 4. The floor brush located in the test chamber 6 rotates with the test chamber 6 and moves from the bottom to the top. Under its own weight, the brush falls back to the bottom of the test chamber 6 and collides with the wooden floor, tile, or carpet on the surface of the simulation board 9, thus repeatedly simulating the impact of the brush falling on different materials. When the brush touches the guide bar 10 during the fall, the arc surface of the guide bar 10 can change the impact angle of the brush after the fall, thereby conducting impact tests on multiple surfaces of the brush. The sliding impact part 8 can be fixed by the screw 11 and nut 13 to adjust the length of the test chamber 6, thereby simulating the impact of the brush falling at different heights.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
