Detailed Implementation

[0020] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] Please see the appendix Figure 1-4 The purpose of this embodiment is to provide an internal air recirculation system for a sweeper, including: a vehicle body 1, a compartment 2 provided on the vehicle body 1, and an air circulation cleaning system 3 arranged in the compartment 2.

[0023] In this embodiment, the dust collection cylinder 31 in the air circulation cleaning system 3 is connected to one end of the first pipe 34, and the other end of the first pipe 34 is connected to the second accommodating space 310. The upper part of the second accommodating space 310 is connected to one end of the flow channel 311 through the partition 314. The other end of the flow channel 311 is connected to one end of the third pipe 36, and the other end of the third pipe 36 is connected to the outside of the carriage 2.

[0024] An air filter 38 is installed in the middle of the third pipe 36. The third pipe 36 is also connected to one end of the second pipe 35. The connection between the third pipe 36 and the second pipe 35 is located above the air filter 38. The other end of the second pipe 35 is connected to the dust collection cylinder 31. An air quality monitor 37 is installed in the flow channel 311 near the third pipe 36.

[0025] Specifically, below the partition 314 is an impurity filter grid 313, and a second receiving space 310 is formed between the partition 314 and the impurity filter grid 313. The first pipe 34 extends into the second receiving space 310, which is used to accommodate larger impurities such as leaves. Below the impurity filter grid 313 is a collection box 312, and a first receiving space 39 is formed between the collection box 312 and the impurity filter grid 313. The first receiving space 39 is used to accommodate particulate impurities such as dust.

[0026] In this embodiment, a negative pressure fan 315 is mounted on the partition 314, a filter screen 316 is attached to the lower part of the partition 314, covering the negative pressure fan 315, and an air filter grille is attached to the upper part of the partition 314, covering the negative pressure fan 315. The negative pressure fan 315 rotates at high speed under the drive of a motor, generating negative pressure. The filter screen 316 prevents impurities from entering near the negative pressure fan 315, and the air filter grille performs preliminary filtration of the air.

[0027] It should be noted that a cleaning brush 32 is located at the front of the vacuum cleaner 31, with the opening of the vacuum cleaner 31 facing the cleaning brush 32. The opening of the vacuum cleaner 31 is a suction nozzle. It should be noted that the vacuum cleaner 31 is existing technology and will not be described further. A baffle 33, L-shaped and semi-encircling the cleaning brush 32, is located away from the vacuum cleaner 31. As the cleaning brush 32 rotates at high speed, the baffle 33, along with the cleaning brush 32 itself, throws dust and impurities towards the suction nozzle and into the vacuum cleaner 31. Several water spray nozzles are also provided around the cleaning brush 32. When the cleaning brush 32 rotates, the water spray nozzles work together to spray water, improving the cleaning effect.

[0028] During operation, impurities such as leaves and dust enter the second containment space 310 through the first pipe 34 under the action of the vacuum tube 31. Small particles such as dust enter the first containment space 39 through the impurity filter grille 313 and are collected in the collection box 312. Larger impurities such as leaves are temporarily stored in the second containment space 310. Under the action of the vacuum tube 31, the air that enters the second containment space 310 along with the impurities enters the flow channel 311 through the partition 314. Part of the air is discharged to the outside of the carriage 2 through the air filter 38 in the third pipe 36, and the other part of the air enters the vacuum tube 31 through the second pipe 35 and then re-enters the first pipe 34 for secondary circulation filtration.

[0029] It should be noted that, in the preferred embodiment, since the air filter 38 purifies a limited volume of air per unit time, and due to its interception effect, most of the air that does not meet the standards after passing through the air quality monitor 37 enters the dust collection cylinder 31 through the second pipe 35 and then re-enters the first pipe 34 for secondary or multiple circulation filtration. The remaining air filtered by the air filter 38 is discharged from the vehicle compartment 2. Further, in the preferred embodiment, the filtration parameters of the air filter 38 can be adjusted based on the monitoring data of the air quality monitor 37 in the flow channel 311, i.e., based on the air quality data in the flow channel 311, thereby changing the volume of air discharged from the vehicle compartment 2 and the volume of air entering the secondary or multiple circulation filtration.

[0030] Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model shall be included within the protection scope of this utility model.
