[0002] The dust collection device of the sanding machine is a device used to collect and remove the dust generated by sanding during the sanding process. The device usually consists of one or more dust collection fans, a filtering system and a dust collection pipe connected to the working surface of the sanding machine. During the sanding process, the fan of the dust collection device sucks the generated dust into the pipe, and then filters it through the filtering system, and discharges the clean air into the environment, while the collected dust is stored or discharged into a designated container, thereby effectively protecting the operating environment and the health of the workers;

[0003] Existing vacuum cleaners often face the problem of blockage caused by large impurities during the cleaning process. These large particles are easily stuck in the suction port or filter net of the vacuum cleaner, causing the device to malfunction. In addition, it is inconvenient to clean the water filter in the vacuum cleaner. However, the existing cleaning method is usually cumbersome, requiring the disassembly of multiple parts, and easily causing the water filter to be damaged or lost. These problems bring inconvenience to users and reduce the user experience of the vacuum cleaner. Utility Model Content

[0024] In this embodiment, a sealing plug 15 is engaged with the middle of the housing 1 , and a sealing plug 15 is also engaged with the bottom of the housing 1 .

[0025] Water is injected between the inner wall of the shell 1 and the partition 11, and the water level is not higher than the highest position of the sealing plug 15. The sealing plug 15 can seal the screw hole penetrating the shell 1 to prevent the water inside the shell 1 from flowing out.

[0026] In this embodiment, the rear end of the sealing plug 15 is provided with threads, and the front part of the housing 1 is provided with two screw holes penetrating to the interior.

[0027] The sealing plug 15 is connected to the housing 1 via threads and can maintain or release the sealing of the screw hole of the housing 1 .

[0028] In this embodiment, a plurality of special-shaped holes are opened at the rear of the wind shield 5 , a round hole is opened at the bottom of the wind shield 5 , and a round hole is opened at the top of the housing 1 .

[0029] Dust enters the interior of the hood 5 through the irregular hole at the rear of the hood 5 and enters the interior of the housing 1 through the circular hole at the bottom of the hood 5.

[0030] In this embodiment, a circular hole is opened on the top of the partition 11, and the air duct 9 has a Z-shaped appearance.

[0031] The airflow can enter the air duct 9 through the circular hole of the partition plate 11 and be discharged from below the liquid surface of the water under the guidance of the air duct 9 .

[0032] In this embodiment, two strip-shaped protrusions are provided at the inner bottom of the housing 1 , and the distance between the two sides of the filter screen 12 matches the length of the two sides of the inner wall of the housing 1 .

[0033] Both sides of the filter screen 12 are connected to the housing 1 by being placed on the top of the strip-shaped protrusions, and can intercept impurities in the water.

[0034] In this embodiment, T-shaped holes are formed on both sides of the stopper 7 , and screw holes are formed on both sides of the housing 1 .

[0035] The stopper 7 can be fixed to the housing 1 by means of bolts 14 and seals the front of the housing 1 so that the housing 1 does not leak.

[0036] It should be noted that the utility model is a dust collecting device with a filtering function, which can separate the impurities of different sizes sucked in when in use, and can clean the fine impurities filtered by water. The specific implementation method is to rotate the sealing plug 15 at the highest point, remove it from the shell 1, and inject water into the inside of the shell 1 through the corresponding screw hole. When the height of the water surface in the shell 1 is higher than the bottom of the air duct 9 and slightly lower than the screw hole corresponding to the highest sealing plug 15, stop injecting water, and tighten the sealing plug 15 to the screw hole to seal the shell 1.

[0037] Then, the fan 4 is started, and the fan 4 draws out the air inside the housing 1, so that the pressure inside the housing 1 is reduced. The air outside the housing 1 will enter the housing 1 through the wind hood 5 under the action of the pressure difference. When the air enters the housing 1, the debris and dust generated by the sander 2 are brought into the housing 1 together. The air rises from under the water surface through the air duct 9 and is discharged from the housing 1 through the fan 4. After the dust and debris enter the housing 1, the heavier dust and debris fall into the material box 10, and the lighter dust and debris move with the air to the air duct 9 and are captured by the water when the air passes through the water, so that the air is purified;

[0038] After use, remove the lowest sealing plug 15 to drain the water inside the housing 1. During the process of water flowing out of the housing 1, dust and debris in the water are intercepted by the filter 12, and the dust and debris are deposited inside the housing 1. Remove the two bolts 14 to release the fixing of the bolts 14 to the stopper 7, remove the stopper 7, release its sealing to the housing 1, and then take out the filter 12 for replacement or cleaning;

[0039] By providing the dust filtering mechanism 3, the dust collecting device can separate dust and debris of different sizes, thereby enhancing the filtering effect, and can also absorb fine dust and debris through water, thereby further improving the filtering effect.

[0040] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
