[0022] Refer to Figure 1 and Figure 2 , a collection drawer 15 is slidably connected to the front of the collection box 3. A pressure relief port 16 is opened on the surface of the collection box 3, and the pressure relief port 16 is located above the collection drawer 15. A dust-proof net 17 is fixedly connected to the inside of the pressure relief port 16.

[0023] As a technical optimization solution of the present utility model, through the settings of the collection drawer 15, the pressure relief port 16 and the dust-proof net 17, the dust collected in the collection box 3 can be stored, and the air pressure in the collection box 3 can be kept stable, thereby ensuring the normal operation of the negative pressure machine 8, and the dust-proof net 17 can prevent dust from overflowing outward through the pressure relief port 16.

[0024] Reference Figure 3 and Figure 4 On the surface of the rotating shaft 12, a main transmission wheel 18 is symmetrically sleeved. On the surface of the rotating shaft 13, a driven transmission wheel 19 is sleeved, and the driven transmission wheel 19 is in transmission connection with the main transmission wheel 18 through a transmission belt.

[0025] As a technical optimization solution of the present utility model, through the settings of the main transmission wheel 18 and the driven transmission wheel 19, the three brush disks 14 can be driven to rotate synchronously, thereby improving the cleaning effect.

[0026] Reference Figure 2 and Figure 1 The combined length of the three brush disks 14 is greater than the width of the bottom of the mounting frame 4, and the height of the brush disk 14 is lower than the height of the brakeable universal wheel 2.

[0027] As a technical optimization solution of the present utility model, through the setting that the combined length of the three brush disks 14 is greater than the width of the bottom of the mounting frame 4, the movement path of the mounting frame 4 can be covered, thereby improving the cleaning range. Through the setting that the height of the brush disk 14 is lower than the height of the brakeable universal wheel 2, it can ensure that the brush disk 14 contacts the ground.

[0028] Reference Figure 1 On the top of the mounting frame 4, a battery pack 20 is symmetrically and fixedly connected, and the battery pack 20 is electrically connected to the electric slide rail 5, the negative pressure machine 8 and the rotating motor 11 respectively.

[0030] Reference Figure 2 The number of the dust suction heads 7 is several, and the several dust suction heads 7 are arranged evenly.

[0031] As a technical optimization solution of the present utility model, through the setting of the several dust suction heads 7, the dust suction range can be improved, enabling it to cover the movement path of the mounting frame 4, and further enabling it to cooperate with the brush disk 14 for dust cleaning.

[0032] Working principle and usage process of the present utility model: When the staff uses this negative pressure cleaning device to clean the road surface, first ensure that the battery pack 20 has sufficient power, and then the base 1 can be pushed by the pusher to drive the brakeable universal wheels 2 to move. At this time, start the negative pressure machine 8 and the rotating motor 11. The output end of the rotating motor 11 drives the rotating shaft 12 to rotate, which can further drive the two main transmission wheels 18 to rotate. Then, the two driven transmission wheels 19 are driven to rotate by the transmission belt, and the rotating shaft 13 rotates, so that the three brush disks 14 can rotate. The movement path of the mounting frame 4 is cleaned by the three brush disks 14, and the suction heads 7 on the flow dividing strip 6 suck the dust after cleaning by the negative pressure of the negative pressure machine 8. At this time, the height of the flow dividing strip 6 and the suction heads 7 can be adjusted according to the actual situation through the electric slide rail 5, so as to adapt to dust of different particle sizes. The dust is transmitted to the collection box 3 through the hose 9 and collected by the collection drawer 15 for centralized collection for subsequent unified treatment. At this time, the pressure relief port 16 can ensure the pressure balance in the collection box 3, and the dustproof net 17 can prevent the dust from overflowing outwards through the pressure relief port 16.
