Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and more specifically, to a vacuum cleaner durability testing device and its method of use. Background Technology

[0002] As competition intensifies in the home appliance market, consumers are constantly raising their demands for products. As a frequently used cleaning tool, vacuum cleaners need to undergo durability testing before mass production to ensure their quality.

[0003] The durability of a vacuum cleaner is reflected in many aspects, such as the lifespan of the drive motor, wiring, and accessories, as well as battery life and structural stability. However, the usage of vacuum cleaners varies greatly in different environments. Existing vacuum cleaner testing equipment often focuses on testing a single performance aspect and cannot simulate the actual performance of vacuum cleaners on different floor materials. This results in problems such as low testing efficiency, discrepancies between actual usage and test data, and difficulty in meeting quality control requirements.

[0004] Therefore, a new solution is needed to address these problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a vacuum cleaner durability testing device and its usage method.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a vacuum cleaner durability testing device, comprising a frame, wherein the frame is provided with:

[0007] The drive mechanism includes an electrical control box, a drive motor, and a transmission assembly. The drive motor drives the transmission assembly to rotate. The electrical control box controls the start / stop and speed of the drive motor and records the number of rotations of the transmission assembly within a set time. The electrical control box contains a control module and a detection computer. The outer wall of the electrical control box has a control panel. The drive motor, control module, detection computer, and control panel are all electrically connected. The electrical control box can control the start / stop of the drive motor, and the detection computer records and analyzes the parameters of the vacuum cleaner during the detection process and feeds them back to the control panel.

[0008] The traction mechanism includes a connecting rod and a sliding assembly that are fixedly connected to each other. The connecting rod is rotatably connected to the transmission assembly. When the transmission assembly rotates, it drives the sliding assembly to reciprocate along the length of the frame. The electrical control box is used to record the distance the sliding assembly moves within a set time.

[0009] Two clamping mechanisms are provided. The clamping mechanisms move together with the traction mechanism and have the same direction and distance of movement. Each clamping mechanism includes a clamping component and a connecting component. The clamping component is detachably connected to the traction mechanism through the connecting component. The clamping component is used to connect to the vacuum cleaner. Changing the height and angle of the clamping component connected to the traction mechanism changes the test height and test angle of the vacuum cleaner.

[0010] The frame has symmetrically arranged sockets on both sides and several symmetrically opened grooves on the bottom of the frame. Pressure rods are detachably connected to the grooves by fasteners. A simulation board is detachably connected to the bottom of the frame. The bottom surface of the pressure rod abuts against the top surface of the simulation board. The simulation board can be any wood floor, tile, carpet, cement board, or floor paint board. The vacuum cleaner can be continuously powered by the sockets and charger. The control panel can be set to continuously run the vacuum cleaner for a detection time to detect the service life of the motor and wiring and the stability of the structure. By setting simulation boards of different materials, the wear degree of the vacuum cleaner's floor brush on different materials can be detected.

[0011] As a preferred embodiment of the present invention: the transmission assembly includes a rotating rod, a traction rod, two bearings, and a second connecting rod. The length of the traction rod is greater than the length of the rotating rod. The rotating rod has a first through groove and a second through groove. The second connecting rod is slidably connected in the first through groove. A limit block is fixedly connected to the top end of the second connecting rod. A fastener for fixing the second connecting rod is provided in the second through groove. One end of the rotating rod is fixedly connected to the rotating shaft of the drive motor through the fastener.

[0012] The above structure can drive the transmission components to move back and forth by a drive motor, and the reciprocating distance of the traction rod can be increased or decreased by adjusting the position of the connecting rod two in the through groove one.

[0013] As a preferred embodiment of the present invention: the outer walls of the two bearings are respectively fixedly connected to both ends of the traction rod, the inner wall of the bearing at the end of the traction rod closer to the rotating rod is engaged with the second connecting rod, and the inner wall of the bearing at the end of the traction rod away from the rotating rod is engaged with the first connecting rod. Both the first connecting rod and the second connecting rod are provided with two buckles for limiting the bearings.

[0014] The above structure reduces friction between the traction rod and the rotating rod during reciprocating movement through the bearings, thereby reducing the energy consumption of the drive motor. The buckle restricts the bearings from sliding up and down on connecting rod one or connecting rod two. Adjusting the two bearings to the same height allows the traction rod to move horizontally back and forth.

[0015] As a preferred embodiment of the present invention: the sliding assembly includes a first connecting plate, two second connecting plates, a rotating shaft, and two rollers. One end of the first connecting rod is fixedly connected to the top surface of the first connecting plate, one end of each of the two second connecting plates is symmetrically fixedly connected to the bottom surface of the first connecting plate, both ends of the rotating shaft are fixedly connected to the side of the two second connecting plates that are close to each other, and the two rollers are rotatably connected to the rotating shaft.

[0016] The above structure, through bearings and connecting rods, enables the traction rod to apply cyclic thrust and pull to the sliding component when it reciprocates, thereby driving the sliding component to reciprocate.

[0017] As a preferred embodiment of the present invention: two support rods are symmetrically fixed on the frame, and a sliding groove is formed on the top surface of the support rod. The bottom ends of the two rollers abut against the bottom surfaces of the two sliding grooves respectively. The connecting rod is driven by the pushing or pulling force applied by the traction rod to make the sliding assembly slide on the two support rods.

[0018] The above structure restricts the movement trajectory of the rollers through the slide groove, allowing the sliding component to translate in a straight line. The rollers reduce the friction of the sliding component during movement, thereby reducing the burden on the drive motor.

[0019] As a preferred embodiment of the present invention: the clamping assembly includes a fixed plate, a first support plate, a second support plate, a third support plate, two rubber pads, and a spring. The first support plate and the third support plate are symmetrically fixedly connected to the side wall of the fixed plate on the same side. The two ends of the spring are respectively fixedly connected to the side of the first support plate and the second support plate that are close to each other. The second support plate moves back and forth between the first support plate and the second support plate by the spring. The two rubber pads are respectively fixedly connected to the side of the second support plate and the third support plate that are close to each other.

[0020] The above structure allows the vacuum cleaner handle to be placed between two rubber pads by pulling the second support plate upwards. After the tension applied to the second support plate is removed, the rebound force generated by the spring compression will cause the two rubber pads to clamp the vacuum cleaner handle.

[0021] As a preferred embodiment of the present invention: the connecting assembly includes a handle, a screw, and a connector. One end of the screw is fixedly connected to the handle. The connecting plate and the fixing plate are respectively provided with a through groove and a through hole for the end of the screw away from the handle to pass through. The screw slides back and forth in the through groove along the height direction of the frame. A gasket is provided between the handle and the connecting plate. The connector is threadedly connected to the end of the screw that passes through the through groove.

[0022] The above structure can be tightened or loosened by turning the handle clockwise or counterclockwise. The height and angle of the vacuum cleaner during testing can be adjusted by adjusting the height and angle of the fixed plate.

[0023] As a preferred embodiment of the present invention: the connector consists of a nut and two connecting blocks. The two connecting blocks are symmetrically fixed on the outer wall of the nut along the length of the frame. A slider is fixedly connected to the side of the connecting block near the connecting plate two. Two sliding grooves are provided on the side of the connecting plate two away from the handle. The length of the sliding grooves two is the same as the length of the through groove three. The two sliding grooves two are symmetrically arranged on both sides of the through groove three. The two sliders one are slidably connected in the two sliding grooves two respectively.

[0024] The above structure is designed so that the connecting parts can be restricted to rotate together with the screw by the slider, so as to ensure that the fixed plate can be tightened or loosened when the handle is turned.

[0025] As a preferred embodiment of the present invention, a method of using a vacuum cleaner durability testing device includes the following steps;

[0026] S1: Select the test scenario, choose a simulation board of appropriate material according to the required test scenario, and fix it to the bottom of the frame with several pressure bars and several fasteners;

[0027] S2: Connect the vacuum cleaner, after the vacuum cleaner's floor brush is pressed against the simulation board, pull the second support plate upward and place the vacuum cleaner's handle between the second and third support plates. At this time, remove the tension applied to the second straight plate and use the spring compression to generate a rebound force to drive the two rubber pads to clamp the vacuum cleaner's handle.

[0028] S3: Adjust the test angle and test height of the vacuum cleaner. Adjust the height and tilt angle of the fixing plate according to the handle height and tilt angle of the vacuum cleaner. Turn the handle and fix the fixing plate through the threaded screw and connector.

[0029] S4: Adjust the moving distance of the vacuum cleaner. Adjust the distance between the connecting rod 2 and the drive motor to increase or decrease the rotation radius of the rotating rod, thereby increasing or decreasing the distance that drives the traction mechanism to move back and forth on the two support rods.

[0030] S5: Set detection parameters. The detection time, drive motor speed, number of drive motor rotations, and reciprocating distance of the traction mechanism can be set through the control panel.

[0031] S6: Start / Stop. This function controls the power supply to the drive motor, its start, stop, or emergency stop via several buttons or knobs on the control panel.

[0032] In summary, this invention has the following beneficial effects: The clamping mechanism allows for adjustment of the vacuum cleaner's test height and angle while it is connected; the drive and traction mechanisms enable the vacuum cleaner on the clamping mechanism to move back and forth, simulating vacuuming operations by users of different heights; different materials can be selected to simulate vacuuming operations on different floor surfaces; two clamping mechanisms allow for simultaneous testing of two vacuum cleaners, facilitating performance comparisons between different models; the control panel displays the vacuum cleaner's battery performance when its power is depleted; setting the test time and continuously supplying power to the vacuum cleaner via the control panel allows for testing the lifespan of the motor, wiring, and accessories; and it also tests the structural stability of the vacuum cleaner under prolonged operation. This provides a more comprehensive durability test, with test data more closely reflecting actual usage conditions. A standardized testing plan and quality control requirements can be established to ensure the quality of the vacuum cleaner. Attached Figure Description

[0042] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] Example: A vacuum cleaner durability testing device, such as Figures 1-6 As shown, the frame 1 is made of aluminum alloy. The lightweight and high-strength properties of aluminum alloy ensure the support and structural strength of the frame 1. The frame 1 has a drive mechanism, a traction mechanism, and two clamping mechanisms. The drive mechanism includes an electrical control box 2, a drive motor 3, and a transmission assembly 4. The drive motor 3 is fixedly connected to the top of the frame 1, with its rotating shaft 603 facing downwards. The transmission assembly 4 includes a rotating rod 401, a traction rod 402, two bearings 403, and a connecting rod 404. The rotating rod 401 has a through groove 10 and a through groove 11. The lengths of the through groove 10 and the through groove 11 are the same and perpendicularly connected. The connecting rod 404 slides along the length of the rotating rod 401. The connecting rod 404 is connected to a square limiting block 25 at the top of the connecting rod 404. The side length of the limiting block 25 is greater than the width of the connecting rod 404. The limiting block 25 can restrict the connecting rod 404 from falling out of the connecting rod 404. A fastener 12 for fixing the connecting rod 404 is provided in the connecting rod 404. The fastener 12 consists of a screw 802 and a nut. One end of the rotating rod 401 is fixedly connected to the rotating shaft 603 of the drive motor 3 through the fastener 12. The rotating rod 401 is set horizontally along the transverse side of the frame 1, so that when the drive motor 3 rotates, it can drive the rotating rod 401 to rotate around the drive motor 3 as the center. The drive motor 3 is a servo motor, which can achieve high-precision and high-repeatability position, speed and torque control.

[0044] like Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, the outer walls of the two bearings 403 are fixedly connected to both ends of the traction rod 402. The inner wall of the bearing 403 at the end of the traction rod 402 closest to the rotating rod 401 is engaged with the connecting rod 404. The traction mechanism includes a connecting rod 5 and a sliding assembly 6 fixedly connected to each other. The inner wall of the bearing 403 at the end of the traction rod 402 furthest from the rotating rod 401 is engaged with the connecting rod 5. By adjusting the engagement height of the two bearings 403 on the connecting rod 5 and the connecting rod 404, the traction rod 402 can be adjusted to achieve the desired effect. 2. Horizontally arranged along the transverse side of frame 1, each of the connecting rod 1 5 and connecting rod 2 404 is provided with two buckles 13. The two buckles 13 are symmetrically arranged on both sides of bearing 403. The two buckles 13 can restrict the bearing 403 from sliding up and down on connecting rod 1 5 or connecting rod 2 404. The two bearings 403 make the two ends of the traction rod 402 rotatably connected to connecting rod 1 5 and connecting rod 2 404 respectively, so that when the traction rod 402 moves back and forth with the rotating rod 401, it can drive the connecting rod 1 5 to move back and forth.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the sliding assembly 6 includes a connecting plate 601, two connecting plates 602, a rotating shaft 603, and two rollers 604. One end of the connecting rod 5 is fixedly connected to the top surface of the connecting plate 601, and one end of each of the two connecting plates 602 is symmetrically fixed to the bottom surface of the connecting plate 601. Both ends of the rotating shaft 603 are fixedly connected to one side of the connecting plates 602 that are close to each other. Both rollers 604 are rotatably connected to the rotating shaft 603. Two support rods 14 are symmetrically fixed on the frame 1. The top surface of the support rod 14 is provided with a long groove 15. The bottom ends of the two rollers 604 abut against the bottom surfaces of the grooves 15 respectively. The length of the traction rod 402 is greater than the length of the rotating rod 401. When the end of the rotating rod 401 away from the drive motor 3 moves away from the support rod 14, the traction rod 402 moves away from the rotating shaft 601. When rod 14 rotates, the traction rod 402 pulls the sliding component 6 to slide on the support rod 14 in the direction close to the drive motor 3. When the end of the rotating rod 401 away from the drive motor 3 rotates in the direction close to the support rod 14, the traction rod 402 pushes the sliding component 6 to slide on the support rod 14 in the direction close to the drive motor 3, thereby achieving the effect of driving the sliding component 6 to move back and forth. The width of the roller 604 is smaller than the width of the slide groove 15. The rotating shaft 603 is provided with four buckles 13 to limit the two rollers 604 and prevent the side wall of the roller 604 from abutting against the inner wall of the slide groove 15. The two rollers 604 and the two bearings 403 reduce the friction when the transmission component 4 and the sliding component 6 move, thereby reducing the energy consumption of the drive motor 3.

[0046] like Figures 1-7 As shown, two clamping mechanisms are symmetrically arranged on the side of the two connecting plates 602 that are far apart from each other. The clamping mechanism includes a clamping assembly 7 and a connecting assembly 8. The clamping assembly 7 includes a fixed plate 701, a support plate 702, a support plate 703, a support plate 704, two rubber pads 705, and a spring 706. The support plates 702 and 704 are symmetrically fixed on the same side of the fixed plate 701 away from the connecting plate 602 along the height direction of the frame 1. The two ends of the spring 706 are respectively close to the support plates 702 and 703. The support plate 703 is fixedly connected to the side closest to the support plate 702. The support plate 703 moves back and forth between the support plate 702 and the support plate 703 by compression or tension of the spring 706. Two rubber pads 705 are fixedly connected to the side of the support plate 703 and the support plate 704 that are close to each other. Pull the support plate 703 upward and place the vacuum cleaner handle between the support plate 703 and the support plate 704. At this time, the tension applied to the support plate 703 is removed and the spring 706 generates a rebound force to drive the two rubber pads 705 to clamp the vacuum cleaner handle, so that the vacuum cleaner can be connected to the clamping assembly 7.

[0047] like Figures 1-7 As shown, both rubber pads 705 have arc-shaped indentations on their adjacent sides. The rubber pads 705 have good anti-slip properties and elasticity, allowing them to fit snugly against the vacuum cleaner handle. The fixing plate 701 has a T-shaped groove 26. A slider 27 is slidably connected within the groove 26. One end of the slider 27 protruding from the groove 26 is fixedly connected to the support plate 703. The slider 27 restricts the support plate 703 from shifting when moving with the spring 706. A connecting groove 28 is symmetrically provided on the opposite sides of the support plates 703 and 704. An elastic band can be fitted between the support plates 703 and 704 through the two connecting grooves 28 for shielding during long-term testing. The vacuum cleaner handle detaches from the two rubber pads 705, and the elastic force of the rubber band further enhances the pressure exerted by the two rubber pads 705 on the vacuum cleaner handle, thereby stabilizing the height and angle of the vacuum cleaner during the test. The vacuum cleaner can be connected to the clamping assembly 7 by pulling the support plate 2 703 and attaching the rubber band, which is simple and convenient. The length of the through groove 2 11 is marked with a distance scale, which makes it easy to fix the connecting rod 2 404 in the required position. Adjusting the distance between the connecting rod 2 404 and the drive motor 3 increases or decreases the rotation radius of the rotating rod 401, thereby increasing or decreasing the distance that drives the sliding assembly 6 to reciprocate on the two support rods 14, thus adjusting the reciprocating distance of the vacuum cleaner during the test.

[0048] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the connecting assembly 8 includes a handle 801, a screw 802, and a connector 803. One end of the screw 802 is fixedly connected to the handle 801. The connecting plate 602 has an elongated through slot 16 along the height direction of the frame 1. The top of the fixing plate 701 has a through hole. The end of the screw 802 away from the handle 801 passes through the through hole and the through slot 16. The connector 803 is threaded to the end of the screw 802 that passes through the through slot 16, so that the handle 801, the fixing plate 701, and the connector 803 can pass through the screw. Simultaneously, 802 slides back and forth on connecting plate 602 along the height direction of frame 1. Connecting part 803 consists of a nut and two connecting blocks 18. The two connecting blocks 18 are symmetrically fixed on the outer wall of the nut along the length direction of frame 1. A slider 19 is fixedly connected to the side of connecting block 18 near connecting plate 602. Two long grooves 20 are opened on the side of connecting plate 602 away from handle 801. The length of grooves 20 is the same as the length of through groove 16. The two grooves 20 are symmetrically arranged on both sides of through groove 16. The two sliders 19... 19 is slidably connected to the two slide grooves 20 respectively, so that the handle 801 drives the screw 802 to rotate on the connector 803 while restricting the rotation of the connector 803. A gasket 17 is provided between the handle 801 and the connecting plate 602. The gasket 17 is made of rubber. When the handle 801 is rotated clockwise, the screw 802 increases the distance it passes through the connector 803 through the threaded connection, thereby continuously reducing the distance between the handle 801, the fixing plate 701, the connecting plate 602, the connector 803 and the gasket 17, until the handle 801... The fixing plate 701, connecting plate 602, connector 803 and gasket 17 abut against each other and generate a large pressure to achieve a fixing effect. Turning the handle 801 counterclockwise will loosen the handle 801, fixing plate 701, connecting plate 602, connector 803 and gasket 17 from each other, so that the clamping assembly 7 is detachably connected to the traction mechanism through the connecting assembly 8. When the clamping assembly 7 is fixed to the connecting plate 602 through the connecting assembly 8, the clamping assembly 7 moves together with the sliding assembly 6 and the moving direction, moving distance and moving speed are the same.

[0049] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 8As shown, a simulation plate 9 is detachably connected to the bottom of the frame 1. Six grooves 23 are symmetrically opened at the bottom of the frame 1. A pressure rod 24 is detachably connected to two grooves 23 symmetrically arranged along the length of the frame 1 through fasteners 12. The bottom surface of the pressure rod 24 abuts against the top surface of the simulation plate 9. The three pressure rods 24 can fix the simulation plate 9. The floor brush of the vacuum cleaner abuts against the simulation plate 9. The simulation plate 9 can be any wood floor, tile, carpet, cement board or floor paint board. According to the required test scenario, the service life of the floor brush of the vacuum cleaner on different materials can be tested by placing a simulation plate 9 of appropriate material on the frame 1. The test height and test angle of the vacuum cleaner can be adjusted by changing the height and angle of the clamping component 7 when it is fixed on the connecting plate 602, thereby simulating the state of users of different heights holding the vacuum cleaner and performing vacuuming operations.

[0050] like Figures 1-6 As shown, the electrical control box 2 contains a control module and a detection computer. A control panel 21 is located on the outer wall of the electrical control box 2. The drive motor 3, control module, detection computer, and control panel 21 are all electrically connected. The control panel 21 has knobs and several buttons for controlling the drive motor 3 to power on, power off, start, stop, or emergency stop. When the vacuum cleaner's battery is depleted, the detection computer records the working time and reflects it on the control panel 21, thus obtaining the vacuum cleaner's battery performance. Sockets 22 are symmetrically arranged on both sides of the frame 1. The detection time and the speed of the drive motor 3 are set via the control panel 21, and the reciprocating distance of the vacuum cleaner is set according to the position of the connecting rod 404 on the through slot 11. The vacuum cleaner can continuously perform vacuuming by being powered by the charger and the sockets 22. The durability of the vacuum cleaner is tested. The testing computer can obtain the number of rotations of the drive motor 3 and the number of movements of the sliding component 6 within a set time. The computer can then analyze the lifespan of the vacuum cleaner's motor and wiring to determine the lifespan. Simultaneously, the tightness of the overall structure of the vacuum cleaner can be observed during long-term operation, reflecting its stability over extended use. After the test, the lifespan can be determined by observing the wear of the floor brush roller. This makes the durability testing of the vacuum cleaner more comprehensive, and the test data more closely reflects actual usage conditions. Two clamping components 7 can connect two different models of vacuum cleaners for simultaneous testing, facilitating performance comparison between different models. A standardized testing plan and quality control requirements can be established to ensure the quality of the vacuum cleaner.

[0051] like Figures 1-8 As shown, a method for using a vacuum cleaner durability testing device includes the following steps;

[0052] S1: Select the test scenario. Select a simulation board 9 of appropriate material according to the required test scenario and fix it to the bottom of the frame 1 with several pressure rods 24 and several fasteners 12.

[0053] S2: Connect the vacuum cleaner, after the vacuum cleaner's floor brush is pressed against the simulation plate 9, pull the support plate 2 703 upward and place the vacuum cleaner's handle between the support plate 2 703 and the support plate 3 704. At this time, remove the tension applied to the straight plate 2 and use the spring 706 to generate a rebound force to drive the two rubber pads 705 to clamp the vacuum cleaner's handle.

[0054] S3: Adjust the test angle and test height of the vacuum cleaner. Adjust the height and tilt angle of the fixing plate 701 according to the handle height and tilt angle of the vacuum cleaner. Rotate the handle 801 and fix the fixing plate 701 through the threaded screw 802 and connector 803.

[0055] S4: Adjust the moving distance of the vacuum cleaner, adjust the distance between the connecting rod 404 and the drive motor 3 to increase or decrease the rotation radius of the rotating rod 401, thereby increasing or decreasing the distance that drives the traction mechanism to move back and forth on several support rods 14;

[0056] S5: Set detection parameters. Set the detection time, the speed of the drive motor 3, the number of rotations of the drive motor 3, and the reciprocating distance of the traction mechanism through the control panel 21.

[0057] S6: Start / Stop. Control the drive motor 3 to be powered on, powered off, started, stopped, or stopped by several buttons or knobs on the control panel 21.

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