[0025] Example
[0026] like Figure 1 and 2 As shown, the dry and wet sweeper body structure of this embodiment includes a body 1. The interior of the body 1, from front to back, is arranged as a water storage chamber 11, a functional chamber 12, a filter chamber, and a dust collection chamber 13. The dust collection chamber 13 has an openable or closable tailgate 15 at its rear end. The filter chamber is divided into an upper chamber 131 and a lower chamber 132 by a partition. A filter cartridge mounting hole is provided on the partition. A filter cartridge 16 connected to the filter cartridge mounting hole is installed in the lower chamber 132. An openable or closable ash outlet is provided on the side wall of the lower chamber 132. An independent diversion compartment 1 is provided at the rear of the upper chamber 131. 7. The aforementioned diversion chamber 17 is connected to the aforementioned dust collection chamber 13. The aforementioned diversion chamber 17 is provided with an airflow channel that can be selectively connected to the aforementioned upper chamber 131 or lower chamber 132. The aforementioned functional chamber 12 is equipped with a fan 2. The air inlet of the aforementioned fan 2 is connected to and communicates with the aforementioned upper chamber 131 through the guide channel 18. The top of the aforementioned functional chamber 12 is provided with an air hole. The upper part of the aforementioned dust collection chamber 13 is provided with a spray flushing structure 3. The aforementioned water storage chamber 11 is provided with a first pump that is connected to the aforementioned spray flushing structure 3 through a pipeline. The bottom wall of the aforementioned dust collection chamber 13 is provided with an upwardly extending dust extraction pipe 7.
[0027] The dry and wet dual-purpose sweeper body structure of this embodiment has the following two operating modes:
[0028] 1) "Dry suction" operation mode
[0029] like Figure 1 As shown ( Figure 1 (The middle arrow indicates the airflow direction). Before dry suction (referring to the suction of ground debris with low moisture content), the diversion chamber 17 is connected to the lower chamber 132. During operation, the fan 2 is turned on, and the airflow direction is: outside -- dust extraction pipe 7 -- dust collection chamber 13 -- diversion chamber 17 -- lower chamber 132 -- filter cartridge 16 -- upper chamber 131 -- guide channel 18 -- fan 2 -- air vent -- outside. After entering through the upper end of the dust extraction pipe 7, the debris falls into the dust collection chamber 13. The airflow carrying the dust flows along the above route through the first airflow port and is filtered by the filter cartridge 16. The filtered gas is discharged to the outside. The assembly between the filter cartridge 16 and the filter cartridge mounting hole is existing technology and will not be described again.
[0030] 2) "Wet suction" operation mode
[0031] like Figure 2 As shown ( Figure 2The arrow points to the direction of the airflow, and the wet suction is used for garbage and sundries (sewage, etc.) with a high water content. The shunting chamber 17 is in communication with the upper chamber 131. During operation, the fan 2 is turned on, and the airflow flows in the following direction: the outside -- the dust extraction pipe 7 -- the dust collection chamber 13 -- the upper chamber 131 -- the flow guide channel 18 -- the fan 2 -- the air hole -- the outside. The gas does not pass through the lower chamber 132 and the filter cartridge 16.
[0032] After operation, the first pump is turned on to supply water to the spray flushing structure 3 to flush the dust collection chamber 13, so as to avoid the accumulation of sundries in the dust collection chamber 13 and maintain a good environment in the dust collection chamber 13.
[0033] It should be noted that the filter cartridge mounting hole is provided with a component for blocking or opening the filter cartridge mounting hole, which belongs to the conventional technical design of the sweeper, and thus will not be described here. During wet suction, the filter cartridge mounting hole is blocked, and during dry suction, the filter cartridge mounting hole is opened.
[0034] As a preferred embodiment, the spray flushing structure 3 includes two first pipelines 31. The two first pipelines 31 are respectively arranged on the upper portions of the left and right inner walls of the dust collection chamber 13 in the front-rear direction. The two first pipelines 31 are connected to a first main pipeline. The first main pipeline is connected to the first pump. A plurality of flushing nozzles 32 are respectively and intermittently arranged on the two first pipelines 31.
[0035] In the above embodiment, the directions of the plurality of flushing nozzles 32 can be multi-directional, and the flushing nozzles 32 can be arranged to spray water to the upper portion, the lower portion, or the bottom wall of the corresponding side wall of the dust collection chamber 13. A plurality of flushing nozzles 32 can be arranged in each direction. Some flushing nozzles 32 can be arranged to spray water to the front inner wall of the dust collection chamber 13. Of course, the first main pipeline can be provided with a rotating device to rotate the inner wall of the dust collection chamber 13 to realize upward and downward spraying.
[0036] As a preferred embodiment, the spray flushing structure 3 includes two first pipelines 31. The two first pipelines 31 are respectively arranged on the upper portions of the left and right inner walls of the dust collection chamber 13 in the front-rear direction. The two first pipelines 31 are connected to a first main pipeline. The first main pipeline is connected to the first pump. A plurality of flushing nozzles 32 are respectively and intermittently arranged on the two first pipelines 31.
[0037] In the above embodiment, the design of the atomization dust suppression structure is particularly effective in suppressing dust raising during the dumping of garbage from the tailgate 15 of the compartment. Of course, when the dust content is high, the atomization dust suppression structure can be used during operation to reduce the dust content in the gas and reduce the load of subsequent filtration.
[0038] As a preferred embodiment, the atomization dust suppression structure includes two second pipelines. The two second pipelines are respectively arranged on the upper portions of the left and right inner walls of the dust collection chamber 13 in the front-rear direction. The two second pipelines are connected to a second main pipeline. The second main pipeline is connected to the second pump. A plurality of atomization nozzles are respectively and intermittently arranged on the two second pipelines.
[0039] In the above implementation scheme, water is supplied to the second pipeline by the second pump, thereby spraying water mist from the atomizing nozzle to suppress dust in the dust collection chamber 13.
[0040] As a preferred implementation method, such as Figure 3 As shown, the aforementioned diversion chamber 17 contains three independent sub-chambers arranged on the left, middle, and right. The lower ends of the left and right sub-chambers extend downwards to near the bottom of the lower chamber 132, and each of them has an opening at its lower part. The lower end of the middle sub-chamber is closed. The upper chamber 131 is divided into three flow channels arranged on the left, middle, and right by a partition (left A1, middle A2, and right A3 are referred to as A1, A2, and A3, respectively). The front ends of the three flow channels are close to the aforementioned guide channel 18, and the rear ends are connected to the rear sidewall of the upper chamber 131. The partition has sections corresponding to the left and right flow channels. The dust collection chamber 13 has a filter cartridge mounting hole, and a first airflow port e communicating with the middle sub-chamber is opened in the middle part of the upper part of the front side wall. The upper part of the front side wall of the middle sub-chamber is connected to the middle flow channel through a second airflow port f. The left and right sides of the upper part of the front side wall of the dust collection chamber 13 have third airflow ports g that are respectively connected to the left and right sub-chambers. The left and right sub-chambers are respectively provided with a first control device for opening or closing the corresponding third airflow port. The middle flow channel is provided with a second control device for opening or closing the second airflow port.
[0041] In the above implementation scheme, the diversion chamber 17 forms three independent sub-chambers. The left and right sub-chambers are used to connect with or close the lower chamber 132, and the middle sub-chamber connects the dust collection chamber 13 and the upper chamber 131. Furthermore, the upper chamber 131 is also divided into three independent flow channels. The middle flow channel is mainly used to open during wet suction, and the left and right flow channels are mainly used to open during dry suction. Specifically, during dry suction operation, the first control device opens the third airflow port, and the second control device closes the second airflow port. Under the action of fan 2, the airflow direction is: outside -- dust extraction pipe 7 -- dust collection chamber 13 -- third airflow port -- left and right sub-compartments -- lower chamber 132 -- left and right flow channels -- guide channel 18 -- fan -- outside; during wet suction operation, the first control device closes the third airflow port, and the second control device opens the second airflow port. Under the action of fan 2, the airflow direction is: outside -- dust extraction pipe 7 -- dust collection chamber 13 -- second airflow port -- middle flow channel -- guide channel 18 -- fan -- outside. Not only is dry suction separated in the diversion chamber 17, but different flow channels for dry and wet suction are also formed in the upper chamber 131, avoiding mixing of dry and wet suction and ensuring normal operation of each. The airflow channel design is very ingenious and reasonable.
[0042] It should be noted that in this embodiment, the airflow path (or route) between the opened first airflow port e, the intermediate sub-chamber and the second airflow port forms a wet suction airflow channel, and the airflow path (or route) between the opened third airflow port and the left or right sub-chamber forms a dry suction airflow channel.
[0043] In this embodiment, the first control device includes a first telescopic device a and a first shutter b, the first telescopic device is installed on the front side wall of the corresponding sub-chamber and has a telescopic end located in the sub-chamber, and the first shutter b is connected to the telescopic end, the first telescopic device is used to drive the first shutter b to move back and forth to close or open the corresponding third airflow port, the second control device includes a second telescopic device c and a second shutter d, the second telescopic device is installed in the middle flow channel through a support, and the telescopic end of the second telescopic device is connected to the second shutter d, the second telescopic device is used to drive the second shutter d to move back and forth to close or open the second airflow port. The first telescopic device and the second telescopic device can be a conventional hydraulic cylinder of a suitable model, and the first shutter and the second shutter can be a vertically and horizontally extending plate body.
[0044] In this embodiment, the front side upper part of the inner wall of the dust collecting chamber 13 corresponding to the first airflow port is provided with a filter structure 4 through a support. The filter structure 4 includes two mounting plates distributed left and right, and a filter grid or filter screen is arranged between the mounting plates, which is used to intercept light-weight sundries (such as bags, etc.), and also has the purpose of filtering dust.
[0045] In this embodiment, the top of the filter chamber is provided with an access hole, and a cover plate 19 that can be opened or closed is arranged at the access hole.
[0046] As a preferred embodiment, the rear side wall of the lower chamber 132 is recessed into the dust collecting chamber 13 to form a dust collecting area 20, the lower ends of the left and right sub-chambers extend downward into the dust collecting area 20, and the rear side of the lower ends is provided with an opening, and the dust collecting area 20 is provided with a dust discharging auger 30 extending towards the dust discharging port.
[0047] In the above embodiment, after use, the entire compartment body can be lifted up at the front end, and the dust in the lower chamber 132 will converge into the dust collecting area 20, and then be discharged outward through the dust discharging auger 30. The dust discharging auger 30 is a conventional spiral auger on the market, and its structure is not described here.
[0048] As a preferred embodiment, the lower end face of the shunt chamber 17 is inclined downward to the rear, and the lower part of the shunt chamber 17 is provided with a guide plate 41 extending upward from rear to front, the guide plate 41 extends left and right and is connected with the left and right side walls of the lower chamber 132, and the lower end of the guide plate 41 and the bottom wall of the lower chamber 132 form an ash gap.
[0049] In the above embodiment, the special inclined surface of the lower end of the left and right sub-chambers (i.e. the bottom wall) allows the dust-containing airflow to enter the dust collection area 20 first when it exits the sub-chamber, and after "walking around" in the dust collection area 20, it flows upward along the guide plate 41 towards the lower filter cartridge 16, which allows some dust to "stay" in the dust collection area 20. At the same time, the design of the guide plate 41 makes it easier for the airflow to flow towards the filter cartridge 16, thereby reducing the load on the fan 2 and reducing energy consumption.
[0050] In this embodiment, inclined plate surfaces are provided at the corners of the dust collection chamber 13 to prevent dust accumulation at the corners of the dust collection chamber 13.
[0051] As a preferred embodiment, a dust collection cover 51 is provided in the upper part of the dust collection chamber 13, the lower part of the dust collection cover 51 is open, and the upper end of the dust extraction pipe 7 extends into the dust collection cover 51.
[0052] In the above embodiment, the front end of the dust collection cover 51 is close to the front side of the upper part of the dust extraction pipe 7, and there is a large space between the rear end of the dust collection cover 51 and the rear side of the upper part of the dust extraction pipe 7, so that the debris coming out of the dust extraction pipe 7 will not "spray" everywhere.
