[0036] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary, and embodiments of the present application are described in detail below.

[0037] Reference is made below to Figures 1-7 A recycling bin 10 according to an embodiment of the present application is described below, which can be applied to a scrubbing assembly 100, and the scrubbing assembly 100 can be applied to a scrubber 1000.

[0038] In combination Figures 3-6 As shown in the drawings, the recycling bin 10 according to an embodiment of the present application can mainly include a bin body 11, a bin cover 12 and a partition 13, wherein the bin cover 12 is arranged on the top of the bin body 11, the partition 13 is arranged in the bin body 11 and cooperates with the bin body 11 to define a recycling storage cavity 14, and the recycling storage cavity 14 is located below the partition 13.

[0039] Specifically, the recovery tank 10 is connected with the suction device, the suction device provides negative pressure for the recovery tank 10 to suck the dirt into the recovery tank 10, ensures the normal work of the scrubber 1000, by covering the tank cover 12 on the top of the tank body 11, so that the tank cover 12 and the tank body 11 can jointly define the inner cavity 101 of the recovery tank 10, by setting the partition plate 13 in the tank body 11, so that the partition plate 13 can define the recovery storage cavity 14 with the tank body 11, so that under the action of the suction device, the gas, sewage and solid waste and other dirt enter the inner cavity 101 of the recovery tank 10, and the sewage and solid waste are limited in the recovery storage cavity 14 by the partition plate 13, and the gas is separated from the recovery storage cavity 14.

[0040] Further, in combination with Figures 3-7 As shown, the partition plate 13 can mainly include a first partition plate part 131, a second partition plate part 132 and an extension part 133, the extension part 133 is arranged in the first partition plate part 131 and extends outward relative to the first partition plate part 131, the recovery storage cavity 14 is provided with a dirt suction channel 111, the dirt outlet end 112 of the dirt suction channel 111 at least partially extends into the extension part 133, the second partition plate part 132 is arranged in the extension part 133 and located outside the dirt suction channel 111, the dirt flowing out of the dirt outlet end 112 of the dirt suction channel 111 falls into the recovery storage cavity 14 after being blocked by the second partition plate part 132 and the top wall of the extension part 133, the extension part 133 includes a third partition plate part 1331 arranged beside the second partition plate part 132, the third partition plate part 1331 is provided with an air outlet 1332, the air outlet 1332 is connected with the recovery storage cavity 14, and the second partition plate part 132 is located between the dirt outlet end 112 of the dirt suction channel 111 and the third partition plate part 1331.

[0041] Specifically, by arranging the extension part 133 in the first partition plate part 131, the extension part 133 extends outward relative to the first partition plate part 131, the recovery storage cavity 14 is provided with a dirt suction channel 111, the dirt outlet end 112 of the dirt suction channel 111 at least partially extends into the extension part 133, the second partition plate part 132 is arranged in the extension part 133 and located outside the dirt suction channel 111, so that when the suction device of the scrubber 1000 sucks the dirt containing sewage, solid debris and gas, the dirt can be sucked into the inside of the recovery tank 10 through the dirt suction channel 111, the dirt flowing out of the dirt outlet end 112 of the dirt suction channel 111 can hit the top wall of the extension part 133, and then fall into the recovery storage cavity 14 after being blocked by the second partition plate part 132, thereby preventing the dirt from splashing and improving the collection efficiency of the dirt.

[0042] Further, the airflow enters from the suction channel 111, passes through the second partition portion 132, and is discharged from the air outlet 1332. In order to ensure the normal operation of the suction device and prevent liquid and solid debris from entering the suction device and damaging the structure of the suction device, the sewage needs to be gas-liquid separated. The third partition portion 1331 is arranged on the side wall of the extension portion 133, and the air outlet 1332 is arranged on the third partition portion 1331. In this way, the space above the partition 13 and the recovery storage cavity 14 can be connected through the air outlet 1332, and the sewage and solid debris in the sewage can be deposited in the recovery storage cavity 14 due to gravity, and the gas can flow out of the recovery storage cavity 14 through the air outlet 1332 and flow into the space above the partition 13. Therefore, the gas-liquid separation function of the recovery box 10 can be realized through the arrangement of the partition 13 without additionally arranging an auxiliary gas-liquid separation mechanism, and the structure of the recovery box 10 can be more simple.

[0043] Further, by arranging the second partition portion 132 between the sewage outlet end 112 of the suction channel 111 and the third partition portion 1331, the second partition portion 132 can shield the sewage during the process of the sewage impacting the top wall of the extension portion 133 and falling back to the recovery storage cavity 14, so as to prevent the sewage from flowing out directly through the air outlet 1332, so that the exhaust gas of the recovery box 10 contains liquid and debris, thereby further improving the reliability of the gas-liquid separation of the recovery box 10.

[0044] Therefore, through the structural design of the first partition portion 131, the second partition portion 132 and the extension portion 133 of the partition 13, the gas-liquid separation of the sewage can be realized without additionally arranging other auxiliary structures, not only the structure is more simple, but also the reliability of the gas-liquid separation of the sewage is higher.

[0045] As shown in FIGS. 1, 2 and 3, the first partition portion 131 is arranged on the partition 13, and the second partition portion 132 is arranged on the first partition portion 131. Figure 3 As shown in FIGS. 1, 2 and 3, the first partition portion 131 is arranged on the partition 13, and the second partition portion 132 is arranged on the first partition portion 131. Figure 4 As shown in FIGS. 1, 2 and 3, the first partition portion 131 is arranged on the partition 13, and the second partition portion 132 is arranged on the first partition portion 131.

[0046] Specifically, by opening the avoiding opening 1311 on the first partition plate part 131, and setting the extension part 133 at the circumferential edge of the avoiding opening 1311, the extension part 133 is arranged to extend upward, that is, the extension part 133 includes four side walls and a top wall, and by setting the second partition plate part 132 at the extension part 133, the second partition plate part 132 is arranged to extend downward, so that the second partition plate 13 and the extension part 133 can jointly form the blocking cavity 134, the outlet end 112 of the dirt suction channel 111 can extend into the blocking cavity 134 through the avoiding opening 1311, and the blocking cavity 134 can be in communication with the recovery storage cavity 14, so that the dirt flowing out of the outlet end 112 of the dirt suction channel 111 can first enter the blocking cavity 134, the blocking cavity 134 can effectively intercept the dirt, so that the dirt can timely and centrally fall into the recovery storage cavity 14, and the dirt is prevented from splashing.

[0047] In combination Figure 3 As shown in the figure, when the recovery tank 10 is placed on a horizontal plane, the height of the lower end surface of the second partition plate part 132 is lower than the height of the outlet end 112 of the dirt suction channel 111. Specifically, when the recovery tank 10 works horizontally, when the dirt enters the blocking cavity 134 from the outlet end 112 of the dirt suction channel 111, the dirt will continue to hit the top wall of the extension part 133 upward due to the suction of the suction device. By setting the height of the lower end surface of the second partition plate part 132 to be lower than the height of the outlet end 112 of the dirt suction channel 111, when the dirt enters the blocking cavity 134 from the outlet end 112 of the dirt suction channel 111, the dirt can be higher than the lower end of the second partition plate part 132, so as to prevent part of the dirt from directly passing over the lower end of the second partition plate part 132 and entering the space above the partition plate 13 through the air outlet 1332, thereby ensuring that the second partition plate part 132 more comprehensively and reliably blocks the dirt, and improving the reliability of the recovery tank 10 in separating the dirt.

[0048] In combination Figure 3 As shown in the figure, when the recovery tank 10 is placed on a horizontal plane, the height of the lower end surface of the second partition plate part 132 is lower than the height of the lowermost end of the air outlet 1332. Specifically, when the recovery tank 10 works horizontally, when the dirt hits the blocking cavity 134, it will fall back due to gravity. By setting the height of the lower end surface of the second partition plate part 132 to be lower than the height of the lowermost end of the air outlet 1332, when the dirt falls back due to gravity, the second partition plate part 132 can more comprehensively shield the air outlet 1332, so as to prevent part of the dirt from directly passing over the lower end of the second partition plate part 132 and entering the space above the partition plate 13 through the air outlet 1332, thereby ensuring that the second partition plate part 132 more comprehensively and reliably blocks the dirt, and improving the reliability of the recovery tank 10 in separating the dirt.

[0049] In combination Figure 3As shown, the second partitioning portion 132 is at least two, and the at least two second partitioning portions 132 are respectively located outside the suction passage 111 on both sides, and the third partitioning portion 1331 is two, and the two third partitioning portions 1331 are respectively located on the opposite two side walls of the extension portion 133. In this way, the recovery tank 10 can be exhausted through the gas outlet 1332 on the at least two third partitioning portions 1331, so as to provide the exhaust efficiency and improve the gas-liquid separation efficiency of the recovery tank 10.

[0050] As shown in Figure 3 、 Figure 4 and Figure 7 , the first partitioning portion 131 has a first position with a higher height and a second position with a lower height away from the first position, the first position is close to the suction passage 111, and the second position is away from the suction passage 111, and the second position is provided with a water inlet 1313, and the water inlet 1313 is in communication with the recovery storage cavity 14. Specifically, by providing the water inlet 1313 on the first partitioning portion 131, the space above the first partitioning portion 131 can be communicated with the recovery storage cavity 14 through the water inlet 1313, and by setting the water inlet 1313 at the second position with a lower height away from the first position, the dirt falling on the first partitioning portion 131 can flow to the water inlet 1313 under the action of gravity and flow into the recovery storage cavity 14 through the water inlet 1313, so as to prevent the dirt from being retained on the first partitioning portion 131, and further ensure the reliability of the recovery tank 10 in separating the dirt.

[0051] Further, the first position can be close to the suction passage 111, and the second position can be away from the suction passage 111, so that part of the dirt flowing out of the suction passage 111 and falling on the first partitioning portion 131 can flow to the water inlet 1313 under the action of gravity and flow into the recovery storage cavity 14, thereby improving the efficiency of dirt recovery and further improving the reliability of the recovery tank 10.

[0052] As shown in Figure 3 、 Figure 4 and Figure 7 , the front end of the first partitioning portion 131 is provided with a water blocking protrusion 1312, the water blocking protrusion 1312 is spaced apart from the extension portion 133, and the water blocking protrusion 1312 and the extension portion 133 jointly define a water blocking flow channel 135, and the water blocking flow channel 135 is in communication with the water inlet 1313.

[0053] Specifically, the gas in the dirt can still be mixed with some liquid after flowing out of the recovery storage cavity 14 through the gas outlet 1332 into the space above the baffle 13. By providing the water blocking protrusion 1312 on at least part of the front side of the first baffle part 131 corresponding to the airflow channel 121, the water blocking protrusion 1312 can jointly define the water blocking flow channel 135 with the front side wall of the extension part 133, and the water blocking flow channel 135 is connected to the water inlet 1313. When the gas and liquid mixture flows to the water blocking protrusion 1312, the liquid can contact the water blocking protrusion 1312 and collect in the water blocking flow channel 135, and then fall back into the recovery storage cavity 14 through the water inlet 1313, and the gas can continue to flow out through the water blocking protrusion 1312. In this way, the water content in the gas can be reduced, and the reliability of the gas-liquid separation of the recovery tank 10 on the dirt can be further improved.

[0054] In combination Figures 3-6 As shown, the tank cover 12 is provided with an airflow channel 121, and the gas in the recovery storage cavity 14 enters the upper side of the first baffle part 131 through the gas outlet 1332 and is discharged from the recovery tank 10 through the airflow channel 121.

[0055] Specifically, by providing the airflow channel 121 in the tank cover 12, the airflow channel 121 is connected to the gas outlet 1332. After the dirt is sucked in and hits the extension part 133 and the second baffle part 132 and falls into the recovery storage cavity 14, the gas in the dirt can flow out of the gas outlet 1332, then enter the upper side of the first baffle part 131, and finally be discharged from the recovery tank 10 through the airflow channel 121 into the suction device, thereby realizing the gas-liquid separation function of the recovery tank 10 and making the flow of the separated gas in the recovery tank 10 more stable and smooth.

[0056] In some embodiments of the present application, the recovery tank 10 can mainly include a tank body 11, a tank cover 12, and a baffle 13. The tank cover 12 is arranged on the top of the tank body 11, and the tank body 11 and the tank cover 12 jointly define an inner cavity 101 of the recovery tank 10. An airflow channel 121 is arranged above the inner cavity 101 of the recovery tank 10. The baffle 13 can mainly include a first baffle part 131, a second baffle part 132, and a third baffle part 1331. The first baffle part 131 and the tank body 11 define a recovery storage cavity 14. The recovery storage cavity 14 can mainly include a blocking cavity 134 formed by the second baffle part 132 and a gas separation cavity 136 formed by the third baffle part 1331 and the second baffle part 132.

[0057] Specifically, by arranging the partition plate 13 in the inner cavity 101, the partition plate 13 can form a recovery storage cavity 14 with the box body 11 below the inner cavity 101, and by arranging an airflow passage 121 above the inner cavity 101, the recovery storage cavity 14 can store the dirt, and the airflow passage 121 can facilitate the flow of gas, making the flow of gas more stable and smooth.

[0058] Further, the second partition plate portion 132 can enclose a blocking cavity 134 and a gas separation cavity 136 enclosed by the third partition plate portion 1331 and the second partition plate portion 132, both of which are located in the recovery storage cavity 14, so that when the dirt enters the inner cavity 101 of the recovery tank 10, it can first collide with the blocking cavity 134, then fall into the recovery storage cavity, then the liquid and solid are deposited in the recovery storage cavity 14, and the gas flows out through the gas separation cavity 136, thereby realizing the separation of the gas in the dirt by the recovery tank 10.

[0059] In combination Figure 2 As shown, the floor brush assembly 100 according to the embodiment of the present application can mainly include the above-mentioned recovery tank 10. Specifically, by arranging the recovery tank 10 in the floor brush assembly 100, the recovery path of the sewage is reduced, the loss is reduced, and at the same time, the center of gravity of the scrubber 1000 is lowered, and the operation is more convenient. Arranging the partition plate 13 in the recovery tank 10 can prevent sewage and debris from being sucked into the suction device of the floor brush assembly 100, damaging the structure of the suction device, so as to ensure the normal air intake and exhaust of the suction device, and ensure the normal operation of the suction device and even the scrubber 1000.

[0060] In combination Figure 1 As shown, the scrubber 1000 according to the embodiment of the present application can include the above-mentioned floor brush assembly 100. Specifically, by applying the floor brush assembly 100 to the scrubber 1000, the structural reliability of the scrubber 1000 can be improved, and the product competitiveness of the scrubber 1000 can be improved.
