The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0051] In order to solve the technical problem in the prior art that the drum is easily unevenly soaked and wetted during the process of injecting water into the drum through the water spray holes, thereby affecting the floor cleaning effect, the present invention creates a cleaning component and a cleaning robot, including a bracket, a cleaning member, a first water tank and an air supply component, the air supply component being respectively connected to the first water tank and the water spray chamber, and the air supply component is used to transport the airflow in the first water tank to the water spray chamber to increase the pressure inside the water spray chamber, so that the water head in the water spray chamber is increased, the flow rate is accelerated, and the water flows quickly to each water spray hole, so that the water output at each water spray hole flows to the drum relatively evenly, thereby ensuring that the drum is evenly soaked and the floor cleaning effect is improved.

[0052] The following will be combined with the attached Figures 1 to 16 The cleaning component and the cleaning robot provided in the embodiments of the present invention are described in detail.

[0053] See also Figure 1 The cleaning robot includes a robot body 10 and a cleaning component 20. The cleaning component 20 is installed at the bottom of the robot body 10. When the cleaning robot cleans the ground, the cleaning component 20 contacts the ground to clean the ground.

[0054] See also Figures 2 to 5 , Figure 2 is a schematic diagram of the cleaning component. Figure 3 This is a schematic diagram of the cross-sectional structure of the water tank. Figure 4 It is a schematic diagram of the cross-sectional structure after the bracket and cleaning parts are assembled. Figure 5 yes Figure 4 A partial enlarged view of point A in the middle.

[0055] The cleaning component 20 includes a bracket 21, a cleaning member 22, a first water tank 231 and an air supply component 24. A water spray chamber 210 is provided on the bracket 21. A plurality of water spray holes 211 are provided on the cavity wall of the water spray chamber 210. The cleaning member 22 is installed on the inner side of the bracket 21. One end of the water spray hole 211 is connected to the water spray chamber 210, and the other end faces the cleaning member 22. The first water tank 231 is provided with a water inlet 2300 and an air outlet 2351. The input end of the air supply component 24 is connected to the air outlet 2351, and the output end is connected to the water spray chamber 210.

[0056] The bracket 21 is mounted on the robot body 10, and a cleaning member 22 is mounted on the inner side of the bracket 21. Optionally, the cleaning member 22 is a roller, and the roller is used to clean the ground. The outer side of the bracket 21 has a water spray chamber 210. Optionally, the water spray chamber 210 can be directly opened on the outer side wall of the bracket 21. A plurality of water spray holes 211 are opened at the bottom of the water spray chamber 210. The water in the water spray chamber 210 can flow into the cleaning member 22 through the plurality of water spray holes 211, so that the cleaning member 22 is soaked and cleans the ground. It can be understood that the water in the water spray chamber 210 can also be used to clean the cleaning member 22 to remove dirt on the cleaning member 22.

[0057] The first water tank 231 is installed on the robot body 10. The first water tank 231 has a sewage tank 230 on its outer side. The sewage tank 230 is used to receive the sewage on the cleaning member 22. The first water tank 231 is connected to the sewage tank 230 through the water inlet 2300. The first water tank 231 is used to recover the sewage in the sewage tank 230. Optionally, the sewage tank 230 is arranged adjacent to the bracket 21 and the cleaning member 22 to facilitate the recovery of the sewage generated after the cleaning member 22 cleans the ground. It is understandable that the sewage tank 230 can be provided on the robot body 10 or separately provided. In addition, the sewage tank 230 can also be provided on the box body of the first water tank 231 so that the first box body 231 can recover the sewage in the sewage tank 230.

[0058] The input end and the output end of the air delivery component 24 are respectively connected to the air outlet 2300 and the water spray chamber 210. When in use, the air delivery component 24 is started, and the airflow in the first water tank 231 is delivered to the water spray chamber 210 through the air delivery component 24. In this process, on the one hand, a negative pressure is formed in the first water tank 231, and the sewage in the sewage tank 230 is recovered to the first water tank 231 under the action of the negative pressure. On the other hand, the airflow in the first water tank 231 is delivered to the water spray chamber 210, so that a positive pressure is formed in the water spray chamber 210, so as to achieve the purpose of pressurizing the inside of the water spray chamber 210. In this way, the water head in the water spray chamber 210 increases and the flow rate is accelerated, and it quickly flows to each water spray hole 211. The water output at each water spray hole 211 is relatively uniform and flows to the cleaning member 22, so that the cleaning member 22 is evenly immersed in water, which helps to improve the floor cleaning effect.

[0059] In addition, since the water flow rate in the water spray chamber 210 is relatively fast, the water pressure at the water spray hole 211 is relatively high, so that the water spray hole 211 is not easily blocked.

[0060] In some embodiments, the cleaning component also includes a second water tank 232 and a water delivery component 25, the input end of the water delivery component 25 is connected to the second water tank 232, and the output end is connected to the water spray chamber 210, and the water delivery component 25 can deliver water in the second water tank 232 to the water spray chamber 210.

[0061] Optionally, the first water tank 231 includes a first box body 233, and the second water tank 232 includes a second box body 234. The first box body 233 and the second box body 234 are separated by a partition 235 and are sealed and connected to the first box body 233 and the second box body 234 respectively. The first box body 233, the second box body 234 and the partition 235 are assembled to form the water tank 23, wherein the partition 235 and the first box body 233 are enclosed to form the first water tank 231, and the partition 235 and the second box body 234 are enclosed to form the second water tank 232. In some embodiments, the first box body 233 is further provided with the sewage tank 230, which is arranged between the first water tank 231 and the cleaning member 22, and the second water tank 232 is arranged above the first water tank 231.

[0062] The second water tank 232 is used to store clean water. The water delivery component 25 is respectively connected to the second water tank 232 and the water spray chamber 210. When the water delivery component 25 is started, the clean water in the second water tank 232 is delivered to the water spray chamber 210. Under the pressure of the air delivery component 24, the clean water flows evenly to each water spray hole 211 and flows evenly to the cleaning member 22 through each water spray hole 211.

[0063] Optionally, the water delivery component 25 and the air delivery component 24 are started simultaneously, so that clean water and air flow are delivered to the water spray chamber 210 substantially simultaneously, so that the clean water can flow to each water spray hole 211 in time.

[0064] In some embodiments, the gas delivery component 24 includes an air pump 240, a first pipeline 241 and a second pipeline 242. The air pump 240 has an air inlet end 2400 and an air outlet end 2401. One end of the first pipeline 241 is connected to the air inlet end 2400, and the other end is connected to the first water tank 231. One end of the second pipeline 242 is connected to the air outlet end 2401, and the other end is connected to the water spray chamber 210.

[0065] An air inlet 2400 and an air outlet 2401 are respectively provided at both ends of the air pump 240, the first pipeline 241 is respectively connected to the air inlet 2400 and the first water tank 231, and the second pipeline 242 is respectively connected to the air outlet 2401 and the water spray chamber 210. After starting the air pump 240, the air flow in the first water tank 231 passes through the first pipeline 241, the air inlet 2400, the air outlet 2401 and the second pipeline 242 in sequence and then flows into the water spray chamber 210, thereby pressurizing the water spray chamber 210, so that the water flow velocity in the water spray chamber 210 is accelerated, the lift is farther, and flows to each water spray hole 211.

[0066] In some embodiments, the water delivery component 25 includes a water pump 250, a third pipeline 251 and a fourth pipeline 252. The water pump 250 has a water inlet end 2500 and a water outlet end 2501. One end of the third pipeline 251 is connected to the water inlet end 2500, and the other end is connected to the second water tank 232. One end of the fourth pipeline 252 is connected to the water outlet end 2501, and the other end is connected to the second water tank 232.

[0067] The water pump 250 is provided with a water inlet 2500 and a water outlet 2501 at both ends, respectively. The third pipeline 251 is connected to the water inlet 2500 and the second water tank 232, respectively. The fourth pipeline 252 is connected to the water outlet 2501 and the water spray chamber 210. After starting the water pump 250, the clean water in the second water tank 232 flows into the water spray chamber 210 through the third pipeline 251, the water inlet 2500, the water outlet 2501 and the fourth pipeline 252 in sequence.

[0068] See also Figures 6 to 12 , Figure 6 This is a schematic diagram of the exploded structure of the bracket body, cleaning cover and cleaning parts. Figure 7 It is a schematic diagram of the structure of the bracket body. Figure 8 yes Figure 7 A partial enlarged view of point B in the middle. Fig. 9 It is a schematic diagram of the structure of the cleaning cover. Fig.10 yes Fig. 9 A partial enlarged view of point C in the middle. Fig.11 It is a schematic diagram of the local structure near the middle of the bracket body. Fig.12 Schematic diagram of the structure near the diversion groove.

[0069] In some embodiments, the water spray chamber 210 includes a first flow channel 2100 and a second flow channel 2101. The first flow channel 2100 is parallel to the axial direction of the cleaning member 22. A plurality of water spray holes 211 are arranged at intervals along the length direction of the first flow channel 2100. The second flow channel 2101 is connected to the middle position of the first flow channel 2100, and the second flow channel 2101 is respectively connected to the water delivery component 25 and the gas delivery component 24.

[0070] The water spray chamber 210 includes a first flow channel 2100 and a second flow channel 2101 which are connected. The length of the first flow channel 2100 is relatively long, which is roughly the same as the axial length of the cleaning member 22. A plurality of water spray holes 211 are all opened at the bottom of the first flow channel 2100 and are evenly spaced along the length direction of the first flow channel 2100. The second flow channel 2101 is connected to the middle position of the first flow channel 2100, that is, the first flow channel 2100 and the second flow channel 2101 form a roughly "T" shaped structure.

[0071] The second flow channel 2101 is respectively connected to the water delivery component 25 and the gas delivery component 24 . In other words, the second pipeline 242 of the gas delivery component 24 and the fourth pipeline 252 of the water delivery component 25 are respectively connected to the second flow channel 2101 .

[0072] When in use, start the air pump 240 and the water pump 250, and the airflow in the first water tank 231 is transported to the second flow channel 2101, while the water in the second water tank 232 is also transported to the second flow channel 2101. In this way, in the second flow channel 2101, the airflow and the water flow can be fully and evenly mixed, so that the flow rate of water is increased, and the water flows through the second flow channel 2101 to the middle of the first flow channel 2100, and quickly flows from the middle of the first flow channel 2100 to the two ends of the first flow channel 2100, so that the water flow at each water spray hole 211 is relatively uniform, thereby ensuring that the cleaning element 22 is immersed in water and wetted evenly.

[0073] In some embodiments, the bracket 21 includes a bracket body 212 and a cleaning cover 213. The cleaning cover 213 and the bracket body 212 enclose a water spray chamber 210. The cleaning cover 213 is respectively provided with a water inlet hole 2130 and an air inlet hole 2131. The water inlet hole 2130 is respectively connected to the second flow channel 2101 and the water delivery component 25, and the air inlet hole 2131 is respectively connected to the second flow channel 2101 and the air delivery component 24.

[0074] The bracket 21 includes a bracket body 212 and a cleaning cover 213. The cleaning cover 213 is covered on the bracket body 212 and is surrounded by the bracket body 212 to form a water spray chamber 210. Optionally, the cleaning cover 213 is snapped onto the bracket body 212. For example, a slot 2120 is provided on the bracket body 212, and a snap ring 2132 is provided on the cleaning cover 213. The cleaning cover 213 is installed on the bracket body 212 by snapping the snap ring 2132 into the slot 2120.

[0075] The cleaning cover 213 is provided with a water inlet hole 2130 and an air inlet hole 2131 , which are located close to each other and are respectively connected to the second flow channel 2101 , so that the airflow and clean water entering the water spray chamber 210 are easily mixed in the second flow channel 2101 .

[0076] In some embodiments, a guide groove 2110 is provided on one end surface of the water spray hole 211 facing the cleaning member 22 , one end of the guide groove 2110 is connected to the water spray hole 211 , and the other end is connected to the outside.

[0077] like Fig.11 and Fig.12As shown, the guide groove 2110 is provided on the inner wall of the bracket 21 and is connected to the water spray hole 211. The provision of the guide groove 2110 increases the water outlet area of ​​the end of the water spray hole 211 opening toward the cleaning member 22, so that the water spray hole 211 is not easily blocked. In other words, if the guide groove 2110 is not provided, since the aperture of the water spray hole 211 is small, bubbles are easily generated at the end of the water spray hole 211 opening toward the cleaning member 22 and block the water spray hole 211.

[0078] In some embodiments, one end of the guide groove 2110 is connected to the water spray hole 211 , and the other end faces the middle of the bracket 21 .

[0079] The water spray hole 211 near the left side of the bracket 21 has a corresponding guide groove 2110, one end of which is connected to the water spray hole 211 and the other end is toward the right side of the bracket 21. The water spray hole 211 near the right side of the bracket 21 has a corresponding guide groove 2110, one end of which is connected to the water spray hole 211 and the other end is toward the left side of the bracket 21. In this way, the clean water can be guided toward the middle of the water squeezing part through the water spray hole 211 and the guide groove 2110 to avoid excessive water accumulation at both ends of the cleaning part 22 and cause leakage.

[0080] See also Fig.13 , and refer back to Figure 3 , Fig.13 It is a schematic diagram of the three-dimensional structure of the first box.

One end of the sewage suction channel 2311 is connected to the water inlet 2300 , and the other end is connected to the first water tank 231 .

[0082] The bottom of the first water tank 231 is provided with a column 2310, and optionally, the column 2310 is an integral structure with the first water tank 231. In addition, the column 2310 can also be detachably installed in the first water tank 231, so as to facilitate its cleaning and replacement and avoid clogging of the sewage suction channel 2311.

[0083] A sewage suction channel 2311 is opened along the axial direction (vertical direction) of the column 2310, and the two ends of the sewage suction channel 2311 are respectively connected to the water inlet 2300 and the first water tank 231. When the air pump 240 is started, the air pump 240 forms a negative pressure in the first water tank 231, and under the action of the negative pressure, the sewage in the sewage tank 230 flows into the first water tank 231 through the water inlet 2300 and the sewage suction channel 2311 in turn.

[0084] In this embodiment, the horizontal height of the column 2310 is higher than the bottom of the first water tank 231. By opening a sewage suction channel 2311 in the column 2310, it can ensure that the sewage in the sewage tank 230 can be sucked into the first water tank 231 under the action of negative pressure, and can also prevent the sewage in the first water tank 231 from flowing back into the sewage tank 230.

[0085] In some embodiments, the water inlet 2300 is respectively connected to the sewage tank 230 and the sewage suction channel 2311. After the air pump 240 is started, the sewage in the sewage tank 230 is sucked into the first water tank 231 through the water inlet 2300 and the sewage suction channel 2311 in turn.

[0086] In some embodiments, a groove 2350 is provided on the top wall of the first water tank 231 on one side of the bottom wall of the first water tank 231, one end of the column 2310 facing the top wall of the first water tank 231 is arranged in the groove 2350, and a notch 2312 is provided on the end surface of the column 2310, and the notch 2312 is respectively connected to the sewage suction channel 2311 and the first water tank 231. After the air pump 240 is started, the sewage in the sewage tank 230 flows into the first water tank 231 through the water inlet 2300, the sewage suction channel 2311 and the notch 2312 in sequence.

[0087] Since the partition 235 and the first box body 233 are enclosed to form the first water tank 231, the partition 235 is also the top wall of the first water tank 231. The column 2310 is arranged between the bottom of the first water tank 231 and the partition 235. One end of the column 2310 is connected to the bottom of the first water tank 231, and the other end extends upward into the groove 2350. A notch 2312 is opened on the end surface of the column 2310, that is, the position of the notch 2312 is close to the bottom of the groove 2350. It can be understood that the water level of the bottom of the groove 2350 is relatively high. Therefore, the water level at the notch 2312 is relatively high, which can prevent the sewage in the first water tank 231 from flowing back into the sewage tank 230 through the notch 2312. In this way, even if the sewage water level in the first water tank 231 is high, or the first water tank 231 is in a tilted or inverted state, it is difficult for the sewage in the first water tank 231 to flow into the sewage tank 230 through the notch 2312.

[0088] In some embodiments, the side wall of the groove 2350 extends toward the bottom of the first water tank 231 , further preventing the sewage in the first water tank 231 from flowing back into the sewage tank 230 through the notch 2312 .

[0089] In some embodiments, the second water tank 232 is provided with an air flow channel (not shown), the air flow channel having a first end and a second end, the first end is connected to the air outlet 2351, and the second end is connected to the input end of the air delivery component 24, wherein the horizontal height of the second end is higher than the horizontal height of the first end.

[0090] The air outlet 2351 is connected to the first pipeline 241 through an airflow channel. Specifically, the first end of the airflow channel is connected to the air outlet 2351, and the second end is connected to the first pipeline. Since the horizontal height of the second end is higher than the first end, the sewage entering the airflow channel can flow back to the first water tank 231 under the action of its own gravity, thereby preventing sewage from entering the air pump 240 and the water spray chamber 210.

[0091] Optionally, the air flow channel is provided between the air delivery component 24 and the first water tank 231 , one end of the air flow channel is connected to the first water tank 231 , and the other end of the air flow channel is connected to the air delivery component 24 .

[0092] Specifically, the air flow channel is disposed between the first pipeline 241 and the first water tank 231 , and is communicated with the first pipeline 241 and the first water tank 231 , respectively.

[0093] The air flow channel is opened on the second box body 234, and the first pipeline 241 is connected to the first water tank 231 through the air flow channel. After the air pump 240 is started, the air flow in the first water tank 231 passes through the air flow channel, the first pipeline 241, the air pump 240 and the second pipeline 242 in sequence and then flows to the water spray chamber 210.

[0094] In this embodiment, the arrangement of the airflow channel allows the airflow distance between the first water tank 231 and the first pipeline 241 to be relatively long, thereby reducing the negative pressure suction in the first water tank 231 and preventing the sewage in the first water tank 231 from flowing to the first pipeline 241 and further flowing to the air pump 240 and the water spraying chamber 210 under the negative pressure of the air pump 240, thereby causing damage to the air pump 240 and clogging of the water spraying hole 211 in the water spraying chamber 210. In addition, the second water tank 232 is located above the first water tank 231, so after the air pump 240 is started, if sewage enters the airflow channel, the sewage entering the airflow channel is easily returned to the first water tank 231 under the action of its own gravity, thereby preventing sewage from entering the air pump 240 and the water spraying chamber 210.

[0095] In other words, if the air flow channel is not provided, at this time, since the first water tank 231 is directly connected to the first pipeline 241, when the air pump 240 is started and under the action of negative pressure, the sewage in the first water tank 231 is easily sucked into the first pipeline 241, and flows from the first pipeline 241 to the air pump 240, the second pipeline 242 and the water spray chamber 210 in sequence, thereby causing sewage to enter the water spray chamber 210 and the air pump 240, and causing the water spray hole 211 to be blocked and the air pump 240 to be damaged.

[0096] See also Figures 14 to 16 , Fig.14 This is a schematic diagram of the cross-sectional structure of the water tank near the connection part. Fig.15 yes Fig.14 A partial enlarged view of point D in the middle. Fig.16 It is a three-dimensional structural schematic diagram of the connecting piece.

[0097] In some embodiments, the water tank 23 also includes a connecting member 26, which is installed in the second water tank 232. The second water tank 232 and the first water tank 231 are separated by a partition 235, and an air outlet 2351 is provided on the partition 235. A connecting port 2320 is provided on the side wall of the second water tank 232. An air intake channel 260 is provided in the connecting member 26, and one end of the air intake channel 260 is connected to the first water tank 231 through the air outlet 2351, and the other end of the air intake channel 260 is connected to the gas delivery component 24 through the connecting port 2320.

[0098] The water tank 23 further includes a connector 26, which is installed in the second water tank 232 and has an air suction channel 260. Optionally, the connector 26 can be detachably installed in the second water tank 232 by means of snap connection or the like. An air outlet 2351 is provided on the partition 235, and a connecting port 2320 is provided on the side wall of the second water tank 232. Both ends of the air suction channel 260 are respectively connected to the air outlet 2351 and the connecting port 2320. After the air pump 240 is started, the airflow in the first water tank 231 passes through the air outlet 2351, the air suction channel 260, the connecting port 2320, the first pipeline 241, the air pump 240 and the second pipeline 242 in sequence and then enters the water spray chamber 210 to pressurize the water spray chamber 210.

[0099] In this embodiment, a connector 26 is installed in the second water tank 232, and an air intake channel 260 is provided on the connector 26 to increase the air flow between the first water tank 231 and the first pipeline 241. This helps to reduce the possibility that after the air pump 240 is started, sewage in the first water tank 231 flows into the air pump 240 and the water spray chamber 210, causing water damage to the air pump 240 and blockage of the water spray hole 211 in the water spray chamber 210.

[0100] Furthermore, since the second water tank 232 is located above the first water tank 231, the air suction channel 260 is also located above the first water tank 231. Thus, if sewage enters the air suction channel 260, the sewage will fall into the first water tank 231 under its own gravity, thereby further preventing the sewage from flowing into the air pump 240 and the water spray chamber 210.

[0101] In addition, the connecting member 26 can be detachably installed in the second water tank 232, so that the connecting member 26 can be easily cleaned and replaced. Especially when the air intake channel 260 is blocked, the connecting member 26 can be easily removed for unblocking, thereby ensuring the normal operation of the cleaning robot 100.

[0102] In some embodiments, the air intake channel 260 includes a first air channel 261 and a second air channel 262 that are connected to each other. The first air channel 261 is arranged in a vertical direction and is connected to the air outlet 2351. The second air channel 262 is arranged at an angle to the first air channel 261 and is connected to the connecting port 2320. After the air pump 240 is started, the air flow in the first water tank 231 passes through the first air channel 261, the second air channel 262, the first pipeline 241, the air pump 240 and the second pipeline 242 in sequence and then enters the water spray chamber 210.

[0103] The first air channel 261 is arranged in the vertical direction. When sewage flows to the first air channel 261, the vertically arranged first air channel 261 allows the sewage to quickly flow back to the first water tank 231 under the action of its own gravity, thereby preventing the sewage from entering the second air channel 262 and flowing into the air pump 240 and the water spray chamber 210.

[0104] The second air channel 262 is connected to the second air channel 262 and is arranged at an angle, which can further prevent the sewage in the first air channel 261 from flowing into the second air channel 262. Optionally, the second air channel 262 is arranged substantially horizontally, and the first air channel 261 and the second air channel 262 are substantially inverted "L" shape.

[0105] In some embodiments, the water tank 23 further includes a first seal 236 and a second seal 237 , one end of the air intake channel 260 is sealedly connected to the air outlet 2351 through the first seal 236 , and the other end of the air intake channel 260 is sealedly connected to the connecting port 2320 through the second seal 237 .

[0106] Optionally, the first sealing member 236 and the second sealing member 237 may be silicone sealing members, and the first sealing member 236 and the second sealing member 237 can effectively prevent water in the second water tank 232 from entering the air intake channel 260 .

[0107] In some embodiments, the connecting member 26 has a first connecting end 263 and a second connecting end 264, which are respectively arranged at the two ends of the air intake passage 260, a convex ring 2352 is arranged on the surface of the side of the partition 235 facing the second water tank 232, the first connecting end 263 is installed on the inner side of the convex ring 2352, the air outlet 2351 is located on the inner side of the convex ring 2352, a first mounting groove 2630 is provided on the outer side of the first connecting end 263, the first sealing member 236 is installed in the first mounting groove 2630 and seals against the inner side wall of the convex ring 2352, thereby achieving sealed communication between the air intake passage 260 and the air outlet 2351. A second mounting groove 2640 is provided on the inner side of the second connecting end 264, the second sealing member 237 is installed in the second mounting groove 2640 and seals against the end surface of the communication port 2320, thereby achieving sealed communication between the second sealing member 237 and the communication port 2320.
