Description

Technical Field

[0001] The invention relates to a drip core tightness testing mechanism for a flat plate support of a vacuum cleaner. Background Art

[0002] The vacuum cleaner industry has been upgraded from traditional vacuum cleaners to handheld vacuum cleaners. The new handheld vacuum cleaners have added more functions in floor cleaning, making household dust removal more convenient and labor-saving. The flat tray can be filled with water to add a dripping function to the vacuum cleaner, which can be wet mopped, making mopping more convenient and clean. A drip core is set at the drip port of the flat tray product, which can better control the amount of water dripping. The tightness of the drip core after installation has a greater impact on the amount of water. In the prior art, the operator tests and judges the tightness of the drip core by hand pulling. For batch products, the operator's hands are pulled for a long time, which consumes a lot of energy, makes the hands sore, and has a very high fatigue strength. It is also easy to cause hand injuries during the test process. Summary of the invention

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 and Figure 2As shown, a drip core tightness testing mechanism for a flat tray of a vacuum cleaner is provided, the testing mechanism includes an equipment frame, a positioning seat arranged on the equipment frame, a pulling mechanism (the pulling mechanism has two groups) for sucking the drip core 10 on the flat tray 100 and pulling it upward, and a monitoring system for monitoring the force output by the pulling mechanism. The testing mechanism also includes a driver 30 (a cylinder) arranged on the equipment frame for providing power for the pulling mechanism to move up and down. The equipment frame includes a support platform 20, a plurality of columns 21 arranged on the support platform 20, and a top plate 22 fixed on the top of the plurality of columns 21.

[0022] In this example, the equipment frame has a support plate 23 slidably arranged on a plurality of columns 21 along the up-down direction, the pulling mechanism is arranged on the support plate 23 , and the power output shaft of the driver 30 is fixedly connected to the support plate 23 .

[0023] Specifically, the pulling mechanism includes a suction nozzle that is slidably arranged relative to the support plate 23 in the up-down direction, and a power mechanism that pulls the suction nozzle to move upward. The suction nozzle includes a seat body 402 located below the support plate 23, and a vacuum nozzle head 401 arranged on the lower surface of the seat body 402. The seat body 402 is arranged to slide relative to the support plate 23 through a sliding column 41, and the upper end of the sliding column 41 passes through the support plate 23 upward to the top of the support plate 23. A horizontal block 42 is arranged at the upper end of the sliding column 41, and the power mechanism is used to push the horizontal block 42 to move upward, thereby driving the suction nozzle to move upward.

[0024] Furthermore, the power mechanism includes a seat plate 44 disposed on the upper surface of the support plate 23 and a telescopic cylinder 43 disposed above the seat plate 44. The power output shaft of the telescopic cylinder 43 extends upward and can push the cross block 42 to move upward.

[0025] Furthermore, the monitoring system includes a pressure sensor disposed at the bottom of the telescopic cylinder 43 (the pressure sensor is not shown in the figure, buried in the seat plate 44 and located at the bottom of the telescopic cylinder 43), and a signal processing and display device 50 connected to the pressure sensor signal.

[0026] In this example, the positioning seat includes a bottom plate 60, a stopper 61 disposed at the rear side of the bottom plate 60, and limit blocks 62 disposed at the left and right sides of the bottom plate 60. When unloading, the flat plate holder 100 is pushed into the positioning seat, and the stopper 61 and the limit block 62 position the flat plate holder 100, and the limit block 62 can also prevent the flat plate holder 100 from moving upward when the flat plate holder 100 is pulled upward.

[0027] The use of the dripping core 10 tightness testing mechanism of the vacuum cleaner flat tray 100 of the present invention is as follows: first, the flat tray 100 is placed in the positioning seat, and then the driver 30 moves downward and moves the support plate 23 and the pulling assembly thereon downward, until the vacuum nozzle head 401 of the suction nozzle in the pulling assembly contacts the dripping core 10, and the external vacuum generating device evacuates the seat body 402 and the vacuum nozzle head 401, thereby sucking the dripping core 10. After sucking, the power mechanism pushes the cross block 42 upward, and the suction nozzle pulls the dripping core 10 upward until the pressure monitored by the pressure sensor reaches the set value, and then the pulling is stopped. If the dripping core 10 is not pulled out, it means that the tightness meets the requirements.

[0028] In summary, the drip core tightness testing mechanism of the vacuum cleaner flat tray of the present invention can perform an automated pulling test on the tightness of the drip core without the need for manual pulling test, thereby reducing the labor intensity of operators and greatly improving the testing operation efficiency and the economic benefits of the enterprise.

[0029] The above detailed description of the present invention is intended to enable persons familiar with the art to understand the contents of the present invention and implement them. It does not limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
