Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner testing technology, and in particular to a vacuum cleaner testing device. Background Technology

[0002] As people's living standards continue to improve, vacuum cleaners, as a convenient and efficient cleaning tool, have been widely used in homes and commercial spaces. To ensure that the performance and quality of vacuum cleaners meet market demands and relevant standards, comprehensive and precise testing is required in all stages of vacuum cleaner research and development, production, and quality control.

[0003] In current vacuum cleaner testing processes, data interpretation primarily relies on manual operation. Testers need to carefully observe the data displayed by the testing equipment and, based on preset standards and experience, analyze and judge these data one by one to determine whether the vacuum cleaner's various performance parameters meet the standards. However, this traditional manual data interpretation method has many significant drawbacks.

[0004] On the one hand, manual operation greatly increases the workload of testing personnel. During the large-scale production or R&D of vacuum cleaners, a large amount of testing is required, and each test generates a significant amount of data. Testing personnel need to concentrate for extended periods to process this data, which not only consumes a lot of time and energy but also easily leads to fatigue, thus affecting work efficiency.

[0005] On the other hand, human error is prone to occur in manual judgment. Subjective factors such as personal experience, differing judgment standards, and fatigue levels can lead to inconsistent data interpretations. Even experienced testers struggle to guarantee accuracy in every judgment when faced with large amounts of complex data. This human error directly impacts the accuracy and reliability of test results, potentially leading to misjudgments of the vacuum cleaner's performance.

[0006] Therefore, developing a device that can automate vacuum cleaner testing to reduce the workload of testers and improve the accuracy and reliability of test results has become an urgent problem to be solved in the field of vacuum cleaner testing technology. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a vacuum cleaner testing device.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] This utility model embodiment provides a vacuum cleaner testing device, including: an operating table, and a main unit, a vacuum cleaner, a floor brush, a suction meter, a first cylinder, a second cylinder, and a camera placed on the operating table. The vacuum cleaner, the floor brush, the suction meter, the first cylinder, the second cylinder, and the camera are all electrically connected to the main unit. The vacuum cleaner has an air intake at the front end and a gear switch at the rear end. The first cylinder is driven to be connected to an end piece, which is adapted to the gear switch. The second cylinder is driven to be connected to a plug, which is adapted to the air intake. The suction meter is connected to the vacuum cleaner. The camera is located at the rear end of the vacuum cleaner. The floor brush is connected to a plug.

[0010] In one specific embodiment, the rear end of the vacuum cleaner is provided with an indicator light corresponding to the gear switch.

[0011] In one specific embodiment, the vacuum cleaner also has a control display panel at its rear end.

[0018] In one specific embodiment, the operating table is provided with a third support frame, the third support frame is connected to a third cylinder, and the block is drivenly connected to the third cylinder.

[0019] The advantages of this vacuum cleaner testing device compared to existing technologies are as follows: The main unit acts as the core control and data processing unit, electrically connected to the vacuum cleaner, suction meter, first cylinder, second cylinder, and camera. During testing, the first cylinder automatically drives the end-capsule to touch the vacuum cleaner's gear switch, automatically switching between low, medium, and high gears without manual operation, significantly reducing human intervention. Simultaneously, the main unit displays suction data, power, and operating voltage, eliminating the need for manual recording and processing by testers, greatly reducing their workload and improving testing efficiency. Furthermore, the automated control and data acquisition of this testing device avoids the influence of human factors on test results. For example, in gear switching tests, the first cylinder accurately drives the end-capsule to touch the gear switch according to a preset program, ensuring accurate and consistent gear switching. The suction meter measures suction data accurately and in real time and transmits it to the main unit, which then judges the test data according to preset standards, reducing potential deviations from manual judgment and thus improving the accuracy and reliability of the test results.

[0032] See Figures 1 to 3 The specific embodiment shown in this utility model discloses a vacuum cleaner testing device, including: an operating table 10, and a main unit 20, a vacuum cleaner 30, a floor brush 40, a suction meter 50, a first cylinder 60, a second cylinder 70, and a camera 80 placed on the operating table 10. The vacuum cleaner 30, the floor brush 40, the suction meter 50, the first cylinder 60, the second cylinder 70, and the camera 80 are all electrically connected to the main unit 20. The vacuum cleaner 30 has an air intake at its front end and a gear switch at its rear end. The first cylinder 60 is driven to have an end piece 61 connected to it, and the end piece 61 is adapted to the gear switch. The second cylinder 70 is driven to have a plug piece 71 connected to it, and the plug piece 71 is adapted to the air intake. The suction meter 50 is connected to the vacuum cleaner 30. The camera 80 is located at the rear end of the vacuum cleaner 30. The floor brush 40 is connected to a block 90.

[0033] Specifically, the operating platform 10 is placed in a stable working environment, ensuring it has sufficient strength and stability to support the various components placed on it. The main unit 20, vacuum cleaner 30, floor brush 40, suction meter 50, first cylinder 60, second cylinder 70, and camera 80 are then placed in suitable positions on the operating platform 10. The main unit 20, as the control and data processing center of the entire testing device, should be placed in a location convenient for operation and observation. The vacuum cleaner 30 is placed in the central area of ​​the operating platform 10, with its front air intake and rear gear switch facilitating operation of other components. The floor brush 40 is placed near the vacuum cleaner 30 for easy connection and testing. The suction meter 50 is connected to the vacuum cleaner 30 via a suitable pipe, ensuring a tight connection to prevent air leakage from affecting test results. The first cylinder 60 and second cylinder 70 are placed near the vacuum cleaner 30's gear switch and air intake, respectively, according to their transmission connection. The camera 80 is installed at a suitable height and angle at the rear of the vacuum cleaner 30, allowing for clear imaging of the relevant area at the rear of the vacuum cleaner 30. Use wires to electrically connect the vacuum cleaner 30, floor brush 40, suction meter 50, first cylinder 60, second cylinder 70 and camera 80 to the main unit 20 respectively, ensuring that the connection is firm and the contact is good, so as to ensure that the signal can be transmitted accurately.

[0034] The main unit 20 has a preset control program for switching the vacuum cleaner 30's speed settings. This program controls the extension and retraction of the first cylinder 60. When the testing device is started, the main unit 20 sends a control signal to the first cylinder 60 according to the preset program. Upon receiving the signal, the first cylinder 60 begins operation, its drive shaft moving the end piece 61 towards the speed switch of the vacuum cleaner 30. The end piece 61 is compatible with the speed switch, accurately contacting it to switch the vacuum cleaner 30 from the current speed to the next (e.g., from low to medium). During the speed switching process, the suction meter 50 measures the suction power data of the vacuum cleaner 30 in real time and transmits the data to the main unit 20. The main unit 20 simultaneously displays the suction power data, as well as related parameters such as the vacuum cleaner 30's power and operating voltage, allowing testers to fully understand the working status of the vacuum cleaner 30 at different speed settings.

[0035] The main unit 20 includes a pre-programmed control program for the second cylinder 70, which controls the sealing action of the plug 71 against the suction port of the vacuum cleaner 30. When simulating stall and full-dust conditions, the main unit 20 sends a control signal to the second cylinder 70, which drives the drive shaft to move the plug 71 towards the suction port of the vacuum cleaner 30 until it completely seals the port. Even with the suction port blocked, the vacuum cleaner 30 continues to operate. The suction power measured by the suction meter 50 changes, and the main unit 20 records and displays this data. By observing the changes in suction power and the operating status of the vacuum cleaner 30 (such as whether the motor overheats or its speed decreases), the performance of the vacuum cleaner 30 under stall and full-dust conditions can be evaluated, including whether it has overload protection and whether the suction power drop is within a reasonable range.

[0036] Before testing, the block 90 connected to the floor brush 40 was not blocking the suction port of the floor brush 40. When a simulated clogging test of the floor brush 40 was required, the block 90 was manually moved to the position of the suction port of the floor brush 40, completely blocking it. The vacuum cleaner 30 was then started. At this time, the vacuum cleaner 30 performed vacuuming operations through the floor brush 40, but because the suction port was blocked by the block 90, the suction data measured by the suction meter 50 would change. The main unit 20 recorded and displayed these data, and simultaneously observed the working status of the vacuum cleaner 30, such as whether there were any abnormalities in the motor or any abnormal noises from the vacuum cleaner 30, in order to evaluate the operation of the vacuum cleaner 30 under the condition of a blocked floor brush 40.

[0037] During the test, camera 80 continuously captures images of the rear of vacuum cleaner 30 in real time and transmits the image data to host computer 20. Host computer 20 processes and displays the image data transmitted by camera 80. Testers can observe the status of the gear switch and indicator lights at the rear of vacuum cleaner 30 on the host computer 20 screen to help determine whether vacuum cleaner 30 is operating normally. For example, when switching gears, the image from camera 80 can confirm whether the gear switch is accurately switched to the correct position; when vacuum cleaner 30 malfunctions, the indicator lights can be detected promptly through the image from camera 80.

[0038] In other words, the host unit 20 serves as the core control and data processing unit, and is electrically connected to the vacuum cleaner 30, suction meter 50, first cylinder 60, second cylinder 70, and camera 80. During testing, the first cylinder 60 automatically drives the end piece 61 to touch the gear switch of the vacuum cleaner 30, enabling the vacuum cleaner 30 to automatically switch between low, medium, and high gears without manual operation, greatly reducing the need for manual intervention. At the same time, the host unit 20 can simultaneously display suction data, power, and operating voltage information, eliminating the need for testers to manually record and organize this data, greatly reducing the workload of testers and improving testing efficiency. In addition, the testing device avoids the influence of human factors on the test results through automated control and data acquisition. For example, in the gear shifting test, the first cylinder 60 accurately drives the end piece 61 to touch the gear switch according to the preset program, ensuring the accuracy and consistency of gear shifting. The suction meter 50 measures the suction data in real time and accurately and transmits it to the host 20. The host 20 judges the test data according to the preset standard, reducing the deviation that may occur due to manual judgment, thereby improving the accuracy and reliability of the test results. In addition, by driving the end piece 61 to touch the gear switch through the first cylinder 60, the gear switching test of the vacuum cleaner 30 can be performed to detect the performance of the vacuum cleaner 30 at different gears, such as the changes in parameters such as suction power and power, to ensure that the vacuum cleaner 30 can work normally and meet performance requirements at each gear. The second cylinder 70 drives the end piece 71 to block the air intake, which can simulate the stall and dust full state, and test the working performance and protection mechanism of the vacuum cleaner 30 under these extreme conditions, such as whether it will be damaged due to overload, and whether the suction power will drop significantly when the dust is full. The block 90 blocks the suction port of the floor brush 40, which can simulate the scenario of the floor brush 40 being blocked, and detect the operation of the vacuum cleaner 30 when the floor brush 40 is blocked, and evaluate its ability to deal with blockage. This comprehensive testing function helps to discover potential problems in the design and manufacturing process of the vacuum cleaner 30, and provides a strong basis for product optimization and improvement. In addition, the host 20 can not only display various test data synchronously, but also make real-time judgments on these data. During the test, if abnormal data or non-compliance with standards occurs, the host 20 can immediately issue a prompt, enabling testers to promptly identify problems and take corresponding measures. This real-time monitoring and judgment function avoids the tedious process of manually analyzing data one by one in traditional testing, greatly shortening the testing cycle and improving testing efficiency. At the same time, it can also promptly identify product quality problems and reduce the risk of unqualified products entering the market.

[0039] In one embodiment, the vacuum cleaner 30 has an indicator light corresponding to the gear switch at its rear end.

[0040] Specifically, an indicator light corresponding to the gear switch is designed and installed at the rear of the vacuum cleaner 30. The installation position of the indicator light must ensure that it is within the normal shooting range of the camera 80, and the brightness, color, and other characteristics of the indicator light must be clearly visible so that the camera 80 can accurately capture its status. Image processing and comparison software is installed in the host unit 20 to receive the photos transmitted by the camera 80 and perform subsequent processing. Before testing, according to the expected display status of the indicator light at different gears of the vacuum cleaner 30, photos of the indicator light when it is normally displayed at low, medium, and high gears are taken using a high-definition device and stored in the host unit 20 as preset default images. For example, the indicator light is solid green at low gear, solid yellow at medium gear, and solid red at high gear. Photos of these three states are taken and saved respectively. The testing device is started, and the host unit 20 controls the first cylinder 60 to drive the end piece 61 to touch the gear switch according to the preset program, so that the vacuum cleaner 30 switches to low, medium, and high gears in sequence. At each gear position, camera 80 monitors the indicator light status in real time and takes photos of the indicator light at regular intervals (e.g., one photo per second), then transmits these photos to host 20 in real time. Upon receiving the photos from camera 80, host 20's image processing and comparison software automatically compares the monitored indicator light status photos with preset default images. The comparison process can employ algorithms such as pixel-level comparison and feature point comparison to ensure accuracy. If the comparison result shows that the monitored indicator light status photo matches the preset default image, it indicates that the indicator light display is as expected, and host 20 records that the indicator light status for that gear position is normal. If the comparison result is inconsistent, host 20 determines that the indicator light display for that gear position is abnormal, records the abnormal information, and can simultaneously issue an alarm to alert the test personnel.

[0041] In other words, by monitoring the indicator light status in real time through camera 80 and comparing it with a preset default image, it is possible to accurately determine whether the indicator light's display at different levels meets expectations. Compared to manual observation, camera 80 can more accurately capture subtle changes in the indicator light, avoiding the oversights and errors that may occur during manual observation, thereby improving the accuracy of the test. For example, manual observation may lead to inaccurate judgment of the indicator light's color due to factors such as lighting and angle, while camera 80 can accurately record the indicator light's color and brightness information, ensuring the reliability of the test results. In addition, this technology enables automated detection of the indicator light's status, eliminating the need for manual observation and recording of the indicator light's status at each level. The host 20 automatically completes the image reception, comparison, and analysis process, greatly improving testing efficiency, reducing manual intervention, and lowering testing costs. At the same time, automated detection can avoid the influence of human factors on the test results, making the testing process more standardized and regulated. Furthermore, when the indicator light displays abnormally, the host 20 can promptly record the abnormal information and issue an alarm to alert the test personnel. This allows test personnel to quickly locate the problem and take timely measures for repair or adjustment, preventing faulty products from entering the market. For example, if the indicator light for a certain gear position is not lit or displays an incorrect color, it may indicate a problem with the gear switch or indicator light circuit. Timely detection allows for quick resolution of these issues, improving product quality. Furthermore, the host unit 20 records the status information of each gear indicator light during testing, including normal and abnormal conditions. This data can be used for subsequent quality analysis and product improvement. Statistical analysis of a large amount of test data can reveal patterns and trends in indicator light display anomalies, providing a basis for product optimization design. For instance, if the indicator light for a specific gear position is found to frequently malfunction, a thorough inspection and improvement of the circuitry or control logic for that gear position can be conducted.

[0042] In one embodiment, the vacuum cleaner 30 is further provided with a control display panel 31 at its rear end.

[0043] Specifically, a control display panel 31 is designed and installed at the rear of the vacuum cleaner 30, positioned within the field of view of the camera 80 to ensure the camera 80 can clearly capture the content on the control display panel 31. The control display panel 31 has the function of displaying stall and dust full indicators, which can be achieved through specific combinations of icons, text, or indicator lights. For example, a flashing red icon indicates a stalled state, and a solid yellow "Dust Full" text indicates a dust full state. Image recognition and analysis software is installed in the host unit 20 to receive, process, and judge the images captured by the camera 80. Before testing, based on the design requirements and testing specifications of the vacuum cleaner 30, the display indicators that the control display panel 31 should display in the stall and dust full states are determined and stored in the host unit 20 as expected display standards. For example, it is clearly stipulated that the control display panel 31 should display a specific flashing red pattern when stalled, and display the words "Dust Full" in yellow when dust is full.

[0044] When the testing device is started, in the simulated stall state, the host 20 controls the second cylinder 70 to drive the plug 71 to block the air intake of the vacuum cleaner 30, causing the vacuum cleaner 30 to enter the stall state. At this time, the control display panel 31 will display the corresponding stall indicator. The camera 80 takes pictures of the control display panel 31 in real time, acquiring pictures of the control display panel 31 at preset time intervals (e.g., one picture every 0.5 seconds), and sends the pictures to the host 20. In the simulated dust full state, a large amount of dust can be filled into the dust collection device of the vacuum cleaner 30 to make the vacuum cleaner 30 reach the dust full state, and the control display panel 31 will display the dust full indicator. Similarly, the camera 80 takes pictures of the control display panel 31 in real time and transmits them to the host 20. After receiving the pictures transmitted by the camera 80, the host 20's image recognition and analysis software processes the pictures. First, the software preprocesses the pictures, such as denoising and enhancing contrast, to improve image quality. Then, the software uses a preset image recognition algorithm to identify the markings on the control display panel 31 in the pictures. The identified identifier content is compared with the expected display standard stored in the host 20. If the comparison results are consistent, it means that the identifier display of the control display panel 31 in the corresponding state meets the expectations, and the host 20 records the test result of that state as normal; if the comparison results are inconsistent, the host 20 determines that the identifier display is abnormal, records the abnormal information, and can issue an alarm through sound, light, or other means to remind the test personnel.

[0045] In other words, by using camera 80 to capture real-time photos of the control display panel 31 and then performing image recognition and comparison via host 20, it is possible to accurately determine whether the label display on the control display panel 31 meets expectations under stalled and dust-filled states. Compared to manual observation, this automated detection method avoids the influence of human factors (such as visual fatigue, inconsistent judgment standards, etc.) on the test results, greatly improving the accuracy and reliability of the test. For example, manual observation may lead to misjudgments of the label display due to lighting conditions or differences in personal experience, while host 20 can accurately identify the label content through precise image recognition algorithms. In addition, this technology enables automated testing of the label display on the control display panel 31, eliminating the need for manual inspection of each label's display status. Host 20 automatically completes the process of receiving, processing, and judging photos, reducing manual intervention and improving testing efficiency. At the same time, automated testing ensures the consistency and standardization of the testing process, making the test results more comparable. For example, in large-scale production testing, automated testing can quickly and accurately complete the testing of a large number of vacuum cleaners 30, improving production efficiency. When the indicator display on the control display panel 31 does not meet expectations, the host unit 20 can promptly determine this and issue an alarm, enabling testers to quickly identify product problems. For example, if the control display panel 31 does not display the corresponding indicator when the vacuum cleaner is stalled, it may indicate a malfunction in the stall detection circuit of the vacuum cleaner 30 or the drive circuit of the control display panel 31. Timely detection and feedback allow for rapid problem location and repair, preventing substandard products from entering the market and improving product quality. Furthermore, the host unit 20 records the indicator display results of the control display panel 31 for each test state, including normal and abnormal conditions. This data can be used for subsequent quality analysis and product improvement. Statistical analysis of a large amount of test data can reveal patterns and trends in indicator display anomalies, providing a basis for product optimization design. For example, if a high proportion of products in a certain batch exhibit abnormal indicator displays when the dust is full, the relevant circuitry for that batch can be inspected and improved.

[0046] In one embodiment, the operating table 10 is provided with a mounting base 11, and the floor brush 40 is placed on the mounting base 11.

[0047] Specifically, the structure of the mounting base 11 is designed based on parameters such as the shape, size, and weight of the floor brush 40. The mounting base 11 is typically made of materials with sufficient strength and stability, such as metal (aluminum alloy, stainless steel, etc.) or high-strength plastic. The connection method between the mounting base 11 and the operating table 10 is determined, such as bolt fixing, welding, or snap-fit ​​connection. If bolt fixing is used, corresponding holes need to be pre-drilled on the operating table 10, and corresponding mounting holes should also be provided on the mounting base 11 to ensure a firm and reliable connection. Considering the convenience and stability of placing the floor brush 40, a suitable placement groove or positioning structure is designed on the mounting base 11. The shape of the placement groove should match the bottom contour of the floor brush 40, and the depth should ensure that the floor brush 40 will not easily wobble after placement; the positioning structure can be a raised positioning block or a groove used to limit the position of the floor brush 40 on the mounting base 11 and prevent its movement.

[0048] In other words, the mounting base 11 provides a stable platform for the floor brush 40, preventing the floor brush 40 from shaking or shifting during testing and affecting the test results. For example, during a simulated clogging test of the floor brush 40, if the floor brush 40 is not placed stably, the connection between the floor brush 40 and the vacuum cleaner 30 may become loose, affecting the vacuuming effect and the accuracy of the test data. The presence of the mounting base 11 ensures that the floor brush 40 remains in a fixed position during the test, guaranteeing the stability and reliability of the test.

[0049] In one embodiment, the operating table 10 is provided with a fixed base 12, and the vacuum cleaner 30 is connected to the fixed base 12.

[0050] Specifically, the mounting base 12 is designed based on the external dimensions, weight distribution, and stress conditions of the vacuum cleaner 30 during testing. It must ensure that the mounting base 12 can stably support the vacuum cleaner 30 while facilitating its installation and removal. For example, if the vacuum cleaner 30 is cylindrical, the mounting base 12 can be designed with a matching arc-shaped groove structure to increase the contact area and improve stability. The mounting base 12 is made of materials with sufficient strength and rigidity, such as steel or aluminum alloy. Steel has high strength and can withstand significant weight and pressure, but it is relatively heavy; aluminum alloy is lightweight and has good corrosion resistance, allowing for a reduction in the overall weight of the operating table 10 while meeting strength requirements. Furthermore, the surface of the mounting base 12 can be treated with anti-slip features, such as adding anti-slip textures or attaching anti-slip rubber pads, to prevent the vacuum cleaner 30 from sliding during testing. The mounting base 12 can be fixed to the operating table 10 using welding, bolting, or snap-fit ​​connections. Welded connections are strong, but their position is difficult to adjust once fixed. Bolted connections facilitate disassembly and replacement of the mounting base 12, and the position of the mounting base 12 can be fine-tuned by adjusting the tightness of the bolts. Snap-on connections are simple and quick to operate, suitable for situations requiring frequent replacement of the mounting base 12. Based on the structural characteristics of the vacuum cleaner 30, a suitable connection structure can be designed. For example, a slot or hook can be provided at the bottom of the vacuum cleaner 30 to cooperate with the protrusions or snaps on the mounting base 12, enabling a quick connection between the vacuum cleaner 30 and the mounting base 12. Alternatively, an elastic clamp can be provided on the mounting base 12 to clamp and fix the vacuum cleaner 30 using its elastic force.

[0051] In other words, the fixed base 12 provides stable support for the vacuum cleaner 30, effectively reducing its shaking and displacement during testing. When performing tests requiring precise measurement and control, such as suction power tests and gear switching tests, a stable position of the vacuum cleaner 30 ensures the accuracy and reliability of the test data. For example, if the vacuum cleaner 30 shakes when measuring its suction power, it may cause deviations in the suction power meter 50's measurement, affecting the test results.

[0052] In one embodiment, the operating table 10 is provided with a bracket 13, and the camera 80 is connected to the bracket 13.

[0053] Specifically, the structure of the bracket 13 is designed based on factors such as the spatial layout of the operating table 10, the area to be monitored by the camera 80, and the position of the vacuum cleaner 30 during testing. The bracket 13 typically uses a multi-member combination, such as a vertical bar, a horizontal bar, and diagonal braces, to enhance its stability. The vertical bar supports the overall height of the bracket 13, the horizontal bar is used to mount the camera 80 and adjust its horizontal position, and the diagonal braces provide reinforcement to prevent the bracket 13 from wobbling. The bracket 13 is made of a material with sufficient strength and lightness, such as aluminum alloy or stainless steel. Aluminum alloy is lightweight, corrosion-resistant, and easy to install and move; stainless steel has high strength and good stability, making it suitable for use in harsh environments. At the same time, the surface of the bracket 13 material must be smooth to avoid interference with the camera 80's recording. The bracket 13 is installed on the operating table 10 using bolts or welding. The mounting interface for the camera 80 is designed on the horizontal bar of the bracket 13, which can be achieved using threaded connections, snap-fit ​​connections, or magnetic connections. Threaded connections are strong and reliable, but installation and disassembly are relatively troublesome; snap-fit ​​connections are simple and quick to operate, but the connection strength may be slightly weaker; magnetic connections are convenient and flexible, but it is necessary to ensure that the magnetic force is strong enough to prevent the camera from falling.

[0054] In other words, the bracket 13 provides stable support for the camera 80, preventing the camera 80 from blurring or deviating from the target area due to shaking or displacement. By precisely adjusting the height, angle, and position of the bracket 13, the camera 80 can always be pointed at the part that needs to be monitored, such as the indicator light of the vacuum cleaner 30 or the control display panel 31, thereby ensuring that the captured images are clear and accurate, providing a reliable basis for subsequent image analysis and judgment.

[0055] In one embodiment, the operating table 10 is provided with a mounting bracket 14, and the suction meter 50 is connected to the mounting bracket 14.

[0056] Specifically, the structure of the mounting frame 14 is designed based on the size, weight, and testing requirements of the suction meter 50. A frame structure is typically used, consisting of horizontal beams, vertical beams, and support rods to ensure the stability and strength of the mounting frame 14. The horizontal and vertical beams can be made of square or round tubing and assembled together by welding or bolting. The mounting frame 14 is installed onto the operating table 10 using bolts or welding. A suitable connection method is selected based on the interface type of the suction meter 50 and the structural characteristics of the mounting frame 14. Common connection methods include threaded connections, clamp connections, and flange connections. Threaded connections are simple and convenient, but the connection strength is relatively low; clamp connections are suitable for pipe connections and can provide good sealing; flange connections have high strength and good sealing, but installation is relatively complex.

[0057] In other words, the mounting bracket 14 provides stable support for the suction meter 50, preventing inaccurate measurement results due to shaking or displacement of the suction meter 50 during measurement. By precisely adjusting the height and angle of the mounting bracket 14, the measuring port of the suction meter 50 can be tightly fitted with the air intake of the vacuum cleaner 30, ensuring stable airflow during measurement and thus improving the accuracy of suction measurement.

[0058] In one embodiment, the operating table 10 is provided with a first support frame 15, and the first cylinder 60 is connected to the first support frame 15.

[0059] Specifically, the structure of the first support frame 15 is designed based on the size and weight of the first cylinder 60 and the stress it experiences during testing. A frame structure is typically used, consisting of crossbeams, vertical beams, and reinforcing ribs. The crossbeams and vertical beams can be made of square tubing or channel steel to ensure sufficient strength and stability. The reinforcing ribs enhance the overall rigidity of the support frame and prevent deformation during cylinder operation. The first support frame 15 is installed on the operating table 10 using bolts or welding. A suitable connection method is selected based on the interface type of the first cylinder 60 and the structural characteristics of the first support frame 15. Common connection methods include flange connections, threaded connections, and pin connections. Flange connections offer high strength and good sealing, suitable for larger cylinders and higher pressure cylinders; threaded connections are simple and convenient, but have relatively lower connection strength; pin connections are suitable for cylinders that require oscillation or rotation.

[0060] In other words, the first support frame 15 provides a stable mounting base for the first cylinder 60, ensuring that the cylinder will not shake or shift during operation. This helps improve the working accuracy and stability of the cylinder and reduces testing errors caused by cylinder instability. For example, when conducting suction adjustment tests on the vacuum cleaner 30, a stable cylinder can precisely control the suction adjustment components of the vacuum cleaner 30, ensuring the accuracy of the test results.

[0061] In one embodiment, the operating table 10 is provided with a second support frame 16, and the second cylinder 70 is connected to the second support frame 16.

[0062] Specifically, the support frame structure is designed based on the specifications of the second cylinder 70 (such as cylinder diameter, stroke, thrust, etc.) and its specific functional requirements in the testing process. If the cylinder needs to withstand a large lateral force, the support frame should be designed as a frame structure with reinforcing ribs to enhance its bending and torsional resistance. For example, a triangular or trapezoidal reinforcing rib layout can be used to improve the stability of the support frame. The support frame can be fixed to the operating table 10 using bolts. A suitable connection method is selected based on the interface type of the second cylinder 70 and the structural characteristics of the support frame. If the cylinder interface is flanged, a flange connection can be used, aligning the cylinder flange with the flange on the support frame and tightening it with bolts; if the interface is threaded, a threaded connection can be used, screwing the cylinder threaded interface into the threaded hole on the support frame.

[0063] In other words, the second support frame 16 provides a stable support platform for the second cylinder 70, effectively reducing errors caused by vibration and shaking during cylinder operation. This is especially important for testing processes that require precise control of cylinder movement, such as in the performance testing of the vacuum cleaner 30. A stable cylinder can ensure the driving precision of the vacuum cleaner 30 components and improve the accuracy of the test results.

[0064] In one embodiment, the operating table 10 is provided with a third support frame, the third support frame is connected to a third cylinder, and the block 90 is throttle connected to the third cylinder.

[0065] Specifically, the third support frame is designed based on the size and weight of the third cylinder and the movement trajectory of the cylinder and the plug 90 during the test. Considering the location of the dust suction port of the floor brush 40 and the test operation space, the support frame can adopt a frame structure, consisting of horizontal beams, vertical beams, and reinforcing ribs. The horizontal and vertical beams are made of high-strength square tubing to ensure that the support frame has sufficient strength and stability. The reinforcing ribs adopt a triangular layout and are distributed in the key stress parts of the support frame to enhance its bending and torsional resistance. The third support frame is fixed to the operating table 10 using bolts. According to the interface type of the third cylinder and the structural characteristics of the third support frame, a suitable connection method is selected. If the cylinder interface is flanged, a flange connection can be used, aligning the cylinder flange with the flange on the support frame and tightening it with bolts; if the interface is threaded, a threaded connection can be used, screwing the cylinder threaded interface into the threaded hole on the support frame. If a direct connection is used, the plug 90 is fixed to the end of the cylinder piston rod with bolts or clips to ensure a firm connection and not affect the movement of the piston rod. If a linkage mechanism is used, the linkage is connected to the cylinder piston rod and the plug 90 according to the design requirements. The length and angle of the linkage are adjusted so that the plug 90 can be accurately moved to the dust suction port position of the floor brush 40.

[0066] When a simulated clogging test of the floor brush 40 is required, the third cylinder drives the block 90 to move to the suction port position of the floor brush 40, completely blocking the suction port. The vacuum cleaner 30 is then started. At this time, the vacuum cleaner 30 performs vacuuming operations through the floor brush 40, but because the suction port is blocked by the block 90, the suction power data measured by the suction meter 50 will change. The main unit 20 records and displays this data, while simultaneously observing the working status of the vacuum cleaner 30, such as whether the motor malfunctions or whether the vacuum cleaner 30 makes any abnormal noises, thereby evaluating the operation of the vacuum cleaner 30 under the condition of a clogged floor brush 40.

[0067] In other words, by driving the block 90 to move to the suction port of the floor brush 40 via the third cylinder, the potential clogging of the floor brush 40 during actual use can be accurately simulated. This simulation can be repeated, providing reliable experimental conditions for the performance testing of the vacuum cleaner 30 and helping to identify potential problems of the vacuum cleaner 30 under different degrees of clogging.

[0068] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
