Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a sewage tank structure, a cleaning component and a cleaning robot. Background Art

[0002] At present, the rag mops of cleaning robots usually adopt flat block rag trays, bilaterally symmetrical rag trays and roller rag drums. In addition to better cleaning and anti-smudge effects, the roller rag drum has the advantage of being easy to combine with the running water cleaning function. That is, when the robot performs the cleaning task, the drum rotates to clean the ground while clean water is sprayed onto the surface of the drum rag for cleaning, and then the dirty water is scraped off and collected and pumped away.

[0003] Sewage is generally collected by a sewage trough. After being scraped off by the scraper on the sewage trough, the sewage is temporarily stored in the sewage trough and then pumped into the sewage box through the pipeline. However, the sewage scraped off the drum may contain fluff or granular garbage, which flows into the sewage trough with the sewage. When the sewage pipe is pumping sewage, the fluff or granular garbage is easy to block the sewage pipe. Therefore, the sewage pipe in the prior art is easily blocked by garbage.

DETAILED DESCRIPTION

[0028] The present application embodiment provides a sewage tank structure 100, see Figure 1 The sewage tank structure 100 includes a tank body 110 and a filtering structure 120 disposed in the tank body 110 .

[0029] The tank body 110 has a sewage tank 110a and a water scraper rib 111 located at one side of the sewage tank 110a. The sewage tank 110a is used to temporarily store sewage, and the sewage flows into the sewage tank 110a along the water scraper rib 111.

[0030] The filter structure 120 includes at least a first filter component 121 having a first filter gap 121a and a second filter component 122 having a second filter gap 122a. The gap size of the first filter gap 121a is smaller than the gap size of the second filter gap 122a. The first filter component 121 is arranged in the sewage tank 110a, and at least the first filter component 121 is used to enclose a filter space 120a having a water absorption area 120a1 in the sewage tank 110a. The second filter component 122 is arranged on a side of the first filter component 121 away from the water absorption area 120a1, and is located upstream of the first filter component 121 along the sewage flow direction.

[0031] See also Figure 1 , Figure 2 and Figure 4 The second filter assembly 122 may be disposed in the sewage tank 110a or outside the sewage tank 110a.

[0032] The second filter assembly 122 is disposed in the sewage tank 110a. The purpose is that when the second filter assembly filters the sewage, the filtered fluff and garbage can be temporarily stored in the sewage tank 110a, which is convenient for subsequent cleaning. After the sewage enters the sewage tank 110a, it first flows through the second filter assembly 122, then flows through the first filter assembly 121, and enters the filter space 120a with the water absorption area 120a1. The second filter assembly 122 can filter fluff and large particles of garbage, and the first filter assembly 121 can filter fluff and smaller particles of garbage. The sewage is discharged from the sewage tank 110a in the water absorption area 120a1.

[0033] Figure 1 The filter structure 120 shown is only provided with a first filter component 121 and a second filter component 122. In other embodiments, the filter structure 120 may also be provided with one or more other filter components between the first filter component 121 and the second filter component 122. For example, the filter structure 120 may include a third filter component (not shown) having a third filter gap. The third filter component is located between the first filter component 121 and the second filter component 122. The gap size of the third filter gap is larger than the filter gap of the first filter gap 121a and smaller than the gap size of the second filter gap 122a. The third filter component can filter medium-sized garbage, reduce the filtering pressure of the first filter component 121, reduce the probability of the first filter component 121 being blocked by garbage, and further enhance the filtering effect of the filter structure 120.

[0034] See also Figure 2 The embodiment of the present application also provides a cleaning component 1000, which includes a rolling cleaning component 200, a sewage pipe 300, a sewage box 400 and a sewage trough structure 100 provided in any embodiment of the present application, the sewage trough structure 100 is arranged on one side of the rolling cleaning component 200, the scraper rib 111 is in contact with the rolling cleaning component 200, the water suction port 300a of the sewage pipe 300 is arranged in the water suction area 120a1, and the drainage port 300b of the sewage pipe 300 is connected to the sewage box 400.

[0035] The sewage on the rolling cleaning member 200 is scraped off by the scraper ribs 111 and flows into the sewage tank 110a along the scraper ribs 111. After the fluff, large particles of garbage and small particles of garbage in the sewage are filtered by the filtering structure 120, the sewage is sucked into the sewage box 400 by the sewage pipe 300 in the water absorption area 120a1.

[0036] For example, see Figure 2 , the rolling cleaning member 200 can be a roller mop. In another embodiment, the rolling cleaning member 200 can also be a crawler mop.

[0037] See also Figure 2The cleaning component 1000 may also include a clean water spray head 500, a roller comb tooth 600 plate and a dirt-blocking scraper 700. The clean water spray hole, the roller comb tooth 600 and the dirt-blocking scraper 700 are all arranged on the outside of the rolling cleaning member 200. The clean water spray hole sprays clean water to the rag on the surface of the rolling cleaning member 200 for cleaning. The roller comb tooth 600 plate abuts against the rolling cleaning member 200, which can clean large particles of garbage and hair on the rolling cleaning member 200, reduce the filtering pressure of the filter structure 120, and enhance the filtering effect of the filter structure 120; the dirt-blocking scraper 700 is arranged below the roller comb tooth 600 to prevent the garbage attached to the rolling cleaning member 200 from being thrown onto other components when the rolling cleaning member 200 rotates.

[0038] See also Figure 3 and Figure 5 An embodiment of the present application also provides a cleaning robot, which includes the cleaning component 1000 provided in any embodiment of the present application.

[0039] It should be noted that the cleaning component 1000 of the embodiment of the present application is not limited to being installed on a cleaning robot, and other cleaning equipment can also use the cleaning component 1000 of the embodiment of the present application, such as a floor scrubber.

[0040] The sewage tank structure 100 of the embodiment of the present application is provided with a tank body 110 having a sewage tank 110a and a water scraping rib 111, and a filter structure 120 having the tank body 110, the filter structure 120 at least includes a first filter component 121 having a first filter gap 121a and a second filter component 122 having a second filter gap 122a, the first filter component 121 is arranged in the sewage tank 110a, and at least the first filter component 121 is used to enclose a filter space 120a having a water absorption area 120a1 in the sewage tank 110a, and the second filter component 122 is arranged in the first filter component 121. The sewage flowing into the sewage tank 110a along the scraper rib 111, which is away from the water absorption area 120a1 and is located upstream of the first filter component 121 along the water flow direction, first passes through the second filter component 122, and the gap size of the first filter gap 121a is relatively large, which can filter the fluff and large particles of garbage in the sewage. The sewage then passes through the second filter component 122, and the gap size of the first filter gap 121a is relatively small, which can filter the fluff and small particles of garbage in the sewage. The filtered sewage flows into the filter space 120a with the water absorption area 120a1, which can reduce the probability of the sewage pipe 300 being blocked by garbage when extracting sewage.

[0041] It should be noted that the sewage trough structure 100 of the embodiment of the present application is not limited to being installed in the cleaning component 1000 of the cleaning robot, and other electrical equipment can also use the sewage trough structure 100 of the embodiment of the present application.

[0042] The gap size of the first filter gap 121a can be set as needed. For example, the gap size of the first filter gap 121a can be 0.5mm-1mm. The first filter gap 121a within this gap size range can not only ensure the flow rate of sewage when it flows through the first filter gap 121a, but also ensure the filtering effect of the first filter component 121, and reduce the probability of lint and small particles of garbage passing through the first filter gap 121a.

[0043] The gap size of the second filter gap 122a can also be set according to needs. For example, the gap size of the second filter gap 122a can be 2mm-4mm. The second filter gap 122a within this gap size range can not only ensure the flow rate of sewage when flowing through the second filter gap 122a, but also ensure the filtering effect of the second filter component 122, and reduce the probability of lint and large particles of garbage passing through the second filter gap 122a.

[0044] In one embodiment, please refer to Figure 1 The inner wall of the sewage tank 110a and the first filter assembly 121 can together enclose a filter space 120a.

Since most of the fluff and garbage have been filtered, when the sewage in the filter space 120a is drawn out by the sewage pipe, the probability of the sewage pipe being blocked can be reduced. In another embodiment, the sewage tank 110a can also be located on the inner side wall of the other side and the first filter assembly 121 jointly enclose a filter space 120a.

[0045] In another embodiment, the filtering space 120 a may be surrounded by only the first filtering component 121 .

There are still some fine garbage particles in the sewage filtered by the first filter component 121. When the sewage flows through the sedimentation tank 120a2, some of the fine particles can be settled in the sedimentation tank 120a2, which can further reduce the risk of garbage clogging the sewage pipe 300.

[0047] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4The first filter assembly 121 may include a plurality of first filter ribs 1211 disposed at intervals, and a first filter gap 121a is formed between two adjacent first filter ribs 1211.

[0048] In another embodiment, the first filter assembly 121 may include a filter screen having a first filter gap 121 a .

[0049] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The second filter assembly 122 may include a plurality of second filter ribs 1221 disposed at intervals, and a second filter gap 122a is formed between two adjacent second filter ribs 1221. The second filter ribs 1221 have a simple structure, are easy to process and manufacture, and can be integrally formed with the trough body 110.

[0050] In another embodiment, the second filter assembly 122 may include a filter screen having a second filter gap 122a.

[0051] In one embodiment, please refer to Figure 1 The second filter assembly 122 can be located on the side of the sewage tank 110a close to the wiper rib 111, and the sewage tank 110a is divided into a first area 110a1 and a second area 110a2, the first area 110a1 is located between the wiper rib 111 and the second filter assembly 122, the second area 110a2 is located on the side of the second filter assembly 122 away from the first area 110a1, and the first filter assembly 121 is arranged in the second area 110a2. The garbage filtered by the second filter assembly 122 can be temporarily stored in the first area 110a1, and the garbage filtered by the first filter assembly 121 can be temporarily stored in the second area 110a2, so as to facilitate the subsequent cleaning of the garbage.

[0052] In one embodiment, please participate Figure 1 and Figure 4 The width of the first filter rib 1211 is smaller than the width of the second filter rib 1221. The width of the second filter rib 1221 is larger, which can reduce the probability of hair and large particles of garbage clogging the second filter gap 122a and enhance the filtering effect.
