[0058] Embodiment 1

[0059] This embodiment provides a filtering barrel, as Figures 1 to 8 shown, comprising:

[0060] A barrel body 1 is provided with a plurality of filter holes 11, and the filter holes 11 are distributed on the side wall and / or the bottom wall of the barrel body 1, so that the liquid in the dust-containing fluid entering the barrel body 1 can flow out of the barrel body 1 through the filter holes 11;

[0061] A connecting plate 2 is connected to the barrel body 1, so that the filtering barrel can be installed into a recovery container through the connecting plate 2.

[0062] It should be noted that the above-mentioned dust-containing fluid includes solid debris (such as hair, debris, etc.), waste liquid, and dust-containing air flow, etc. The substances absorbed by the cleaning components (such as floor brushes, roller brushes, etc.) of the cleaning equipment from the ground and entering the recovery container are all included in the dust-containing fluid.

[0063] Compared with the prior art, the filtering barrel of the present invention enables the dust-containing fluid entering the recovery container to achieve solid-liquid separation through the filtering barrel, that is, the solid debris in the dust-containing fluid is stored in the filtering barrel, and the liquid in the dust-containing fluid flows out of the filtering barrel through the filter holes 11 and is stored in the liquid storage space between the recovery container and the filtering barrel. In this way, the solid debris and the waste liquid in the dust-containing fluid entering the recovery container are stored in separate areas, which not only facilitates the cleaning of the recovery container, but also avoids the growth of bacteria caused by the mixing of solid debris and waste liquid.

[0064] The barrel body 1 is provided with a liquid inlet 101 and an air outlet 102. The dust-containing fluid enters the barrel body 1 through the liquid inlet 101, and the gas in the dust-containing fluid is discharged out of the barrel body 1 through the air outlet 102.

[0065] The liquid inlet 101 is located above the filter holes 11 to ensure that all the filter holes 11 can play a role in filtering solid debris.

[0066] The air outlet 102 is located at the top end face of the barrel body 1 to avoid the solid debris in the barrel body 1 blocking the discharge of the dust-containing air flow.

[0067] In this embodiment, the top of the barrel body 1 is open, that is, the wall of the air outlet 102 is flush with the inner wall of the barrel body 1. The liquid inlet 101 is located on the side wall of the barrel body 1, and the liquid inlet 101 is located at a position above the middle of the side wall of the barrel body 1 to ensure that the barrel body 1 has a relatively large volume for storing solid debris.

[0068] In this embodiment, the filter holes 11 are formed on the side wall and the bottom wall of the barrel body 1, and all the filter holes 11 are located below the liquid inlet 101. Specifically, the filter holes 11 on the side wall are evenly distributed at a position below the middle of the side wall of the barrel body 1. Preferably, the filter holes 11 are evenly distributed between the middle and the bottom of the side wall of the barrel body 1. The positions of the filter holes 11 are set in this way so that the waste liquid in the dust-containing fluid entering the barrel body 1 can seep out of the barrel body 1 as soon as possible under the action of gravity, and at the same time, ensure that the barrel body 1 has sufficient strength.

[0069] The shapes of all the filter holes 11 can be the same or different, and the sizes of the filter holes 11 can be the same or different. The manufacturer can design the shapes and sizes of the filter holes 11 according to the shape and size of the filter barrel and the environment in which the filter barrel is used.

[0070] Preferably, all the filter holes 11 have the same shape and size so that the filter barrel has a stable filtering effect. The filter holes 11 are circular holes because the number of circular holes is the largest when the same hole area is opened on the same area. The diameter of the filter hole 11 is d, and 2 mm ≤ d ≤ 5 mm. While ensuring that solid debris can be filtered out as much as possible, it is ensured that the waste liquid has a relatively fast seepage speed. In this embodiment, d = 3 mm. The distance between adjacent filter holes 11 on the side wall of the barrel body 1 (the distance between the centers of adjacent filter holes) is L, and 2.5d ≤ L ≤ 6d. While ensuring that the waste liquid has a relatively fast seepage speed, it is ensured that the barrel body 1 has sufficient strength. In this embodiment, L = 3d. The distance between adjacent filter holes 11 on the bottom wall of the barrel body 1 is S, and S ≤ L. Specifically, 2d ≤ S ≤ 2.5d. Since the bottom wall of the barrel body 1 bears the greatest gravity and most of the waste liquid seeps out from the filter holes 11 on the bottom wall, in order to accelerate the seepage of the waste liquid, the density of the filter holes 11 on the bottom wall is greater than that of the filter holes on the side wall, that is, S ≤ L. In this embodiment, S = 2d.

[0071] In this embodiment, the shape of the barrel body 1 is a cylindrical barrel to facilitate the cleaning and installation of the filter barrel.

[0072] The connecting plate 2 is connected to the side wall of the barrel body 1 and is located above the liquid inlet 101 to facilitate the assembly of the filter barrel and not affect the introduction of the dust-containing fluid.

[0073] Specifically, the connecting plate 2 is perpendicularly connected to the side wall of the barrel body 1, so that the barrel body 1 is vertically arranged in the recycling container, thereby improving the filtering effect of the filtering barrel. The connecting plate 2 is supported upward by the recycling container and downward by the gravity of the barrel body 1 and the dust-containing fluid inside the barrel body 1. These two forces are easily balanced, enabling the filtering barrel to be stably balanced in the recycling container, having a stable filtering effect, and the connecting plate 2 is in force balance, making its connection with the barrel body 1 firm and reliable.

[0074] In this embodiment, the connecting plate 2 is an annular plate, which is vertically arranged around the outer side of the top end of the side wall of the barrel body 1, that is, the connecting plate 2 is arranged around the outside of the air outlet 102. In some embodiments, there are multiple connecting plates 2, and these connecting plates 2 are vertically arranged around the outer side of the side wall of the barrel body 1.

[0075] To ensure that the dust-containing air flow inside the barrel body 1 is discharged as soon as possible, a wind guiding part 12 is arranged inside the barrel body 1. The wind guiding part 12 is located at the bottom of the barrel body 1 and is opposite to the air outlet 102, so as to guide the dust-containing air flow to the air outlet 102 as soon as possible.

[0076] Specifically, the bottom of the wind guiding part 12 is connected to the bottom wall of the barrel body 1, there is a gap between the side wall of the wind guiding part 12 and the side wall of the barrel body 1, and the filter holes 11 on the bottom wall of the barrel body 1 are arranged around the outside of the bottom of the wind guiding part 12.

[0077] To enable the wind guiding part 12 to have a better guiding effect, the shape of the wind guiding part 12 is a frustum of a cone, and it gradually shrinks inward from its bottom to the top, that is, the side wall of the wind guiding part 12 gradually inclines inward from bottom to top.

[0078] In this embodiment, the shape of the wind guiding part 12 is a frustum of a cone, and the radius of the top end face is smaller than the radius of the bottom end face. The central axis of the wind guiding part 12 is collinear with the central axis of the barrel body 1, that is, the wind guiding part 12 is located at the central position of the bottom of the barrel body 1. The dust-containing air flow inside the barrel body 1 spirally flows upward to the air outlet 102 under the guiding action of the wind guiding part 12 and is then discharged from the air outlet 102 out of the filtering barrel.

[0079] In order to reduce the weight of the barrel body 1, in some embodiments, a cavity is arranged inside the wind guiding part 12, and the cavity wall forms a frustum of a cone inside the barrel body 1. In this embodiment, a groove 13 is opened at the position corresponding to the wind guiding part 12 on the lower end face of the bottom wall of the barrel body 1. The groove 13 is adapted to the wind guiding part 12. Without affecting the guiding effect of the wind guiding part 12, the weight of the wind guiding part 12 can be reduced as much as possible, thereby reducing the weight of the barrel body 1, and the groove 13 is communicated with the liquid storage space of the recycling container, which can increase the liquid storage performance of the recycling container.

[0080] In this embodiment, to ensure that the filtering barrel has a high filtering effect, the number of filtering holes 11 on the bottom wall of the barrel body 1 cannot be too small, and if the bottom area of the air guiding part 12 is too small, it cannot play a guiding role. The ratio of the bottom area of the air guiding part 12 to the upper end face area of the bottom wall of the barrel body 1 is greater than or equal to 1:4 and less than or equal to 1:2. To avoid the air guiding part 12 affecting the filtering effect of the dust-containing fluid, the ratio of the height of the air guiding part 12 to the height of the barrel body 1 is greater than or equal to 1:12 and less than or equal to 1:8, preferably 1:10.

[0081] To improve the filtering effect of the barrel body 1 and prevent the dust-containing airflow from forming turbulence in the barrel body 1 and affecting the filtering of the dust-containing fluid, the filtering barrel further includes a guiding member 3. The guiding member 3 includes an exhaust pipe 31 and a cyclone part 32. The cyclone part 32 is disposed around the outside of the exhaust pipe 31. The exhaust pipe 31 is communicated with the air outlet 102, and the cyclone part 32 is connected to the liquid inlet 101. The dust-containing fluid enters the filtering barrel from 101. Under the guidance of the cyclone part 32 and the exhaust pipe 31, the waste liquid and solid debris quickly fall to the bottom of the barrel body 1 under the action of centrifugal force and gravity. The dust-containing airflow forms a cyclone in the barrel body 1, and then is guided by the air guiding part 12 to converge to the center of the barrel body 1 and is led out through the exhaust pipe 31 via the air outlet 102.

[0082] The cyclone part 32 includes a wind baffle 321 and a spiral plate 322. One end of the wind baffle 321 is connected to one side of the liquid inlet 101, and the other end of the wind baffle 321 is tangent to the exhaust pipe 31. One end of the spiral plate 322 is connected to the top end face of the wind baffle 321, and the other end of the spiral plate 322 is connected to the bottom end face of the wind baffle 321, that is, the spiral plate 322 spirally extends downward from the top end face of the wind baffle 321 to the bottom end face. The inner side wall of the spiral plate 322 is connected to the exhaust pipe 31, and the outer side wall of the spiral plate 322 is connected to the inner side wall of the barrel body 1.

[0083] The wind baffle 321 faces the liquid inlet 101, and the projection of the wind baffle 321 on the liquid inlet 101 can completely cover the liquid inlet 101. Then the included angle α between the wind baffle 321 and the liquid inlet 101 is <90°, so that the dust-containing fluid entering from the liquid inlet 101 is first blocked by the wind baffle 321, eliminating the inertia of most of the waste liquid and solid debris, so that these waste liquid and solid debris fall as soon as possible under the action of gravity. The dust-containing airflow forms a spiral downward cyclone in the barrel body 1 under the guiding action of the wind baffle 321, the spiral plate 322 and the exhaust pipe 31, and then under the guiding action of the air guiding platform 12 at the bottom of the barrel body 1, spirally converges upward to the center and is led out of the filtering barrel through the exhaust pipe 31. Except for most of the waste liquid and solid debris that fall after being blocked by the wind baffle 321, the remaining small part of the waste liquid and solid debris is carried by the dust-containing airflow to do spiral motion, and this part of the waste liquid and solid debris finally falls to the bottom of the barrel body 1 under the action of the centrifugal force of the cyclone and its own gravity.

[0084] To ensure that the wind deflector 321 has both a good blocking and guiding effect and does not affect the entry of the dusty fluid into the barrel 1, 30° ≤ α ≤ 70°. In this embodiment, α = 50°.

[0085] In this embodiment, the wind deflector 321 is a rectangular plate, and the liquid inlet 101 is similar to a rectangle (it is a rectangle when the side wall of the barrel 1 is flattened). The height of the wind deflector 321 (the distance between the upper and lower end faces) is equal to the height of the liquid inlet 101, and the width of the spiral plate 322 is the same as the width of the wind deflector 321 (the distance between the left and right end faces, the left end face is connected to the liquid inlet 101, and the right end face is connected to the exhaust pipe 31).

[0086] The exhaust pipe 31 is a cylindrical pipe, with an air inlet 301 and an air outlet 302 provided at both ends respectively. A fluid passage for the air flow to pass through is provided between the air inlet 301 and the air outlet 302. The air inlet 301 is located inside the barrel 1 and is opposite to the air guiding part 12. The air outlet 302 is communicated with the air outlet 102, so that all the dusty air flow entering the exhaust pipe 31 is led out of the filter barrel through the air outlet 102.

[0087] It should be noted that the lower end of the exhaust pipe 31 (the end with the air inlet 301) is opposite to the air guiding part 12 and has a certain distance, so as to smoothly guide the air flow into the exhaust pipe 31.

[0088] The cyclone part 32 is hermetically connected to the side wall of the barrel 1 to ensure that the air flow can only be introduced into the downstream components through the exhaust pipe 31.

[0089] The flow guide member 3 is detachably installed inside the barrel 1 for cleaning impurities inside the barrel 1. In this embodiment, the flow guide member 3 is detachably installed at the top of the barrel 1. The cyclone part 32 is located inside the barrel 1 and is in sealed contact with the side wall of the barrel 1, and the exhaust pipe 31 is also located inside the barrel 1.

[0090] To improve the connection strength between the flow guide member 3 and the barrel 1, hanging ears 33 are provided on both sides of the flow guide member 3, and ear slots 14 adapted to the hanging ears 33 are provided on the top end face of the side wall of the barrel 1. The hanging ears 33 are snapped into the ear slots 14 to achieve the detachable connection between the flow guide member 3 and the barrel 1. In this embodiment, the hanging ears 33 are located above the cyclone part 32.

[0091] The flow guide member 3 is also provided with a connection frame 34. The connection frame 34 is located above the cyclone part 32 and the exhaust pipe 31 and surrounds the outside of the air outlet 302, so that all the dusty air flow led out from the air outlet 302 enters the connection frame 34. The connection frame 34 is used for guiding the dusty air flow and connecting with other components.

[0092] The bottom end face of the connection frame 34 is hermetically connected to the top of the cyclone part 32 and the exhaust pipe 31 to prevent the leakage of the dusty air flow.

[0093] In this embodiment, the connecting frame 34 is a rectangular frame.

[0094] Embodiment Two

[0095] This embodiment provides a recycling container, such as Figures 9 to 13 , including the filtering barrel provided in Embodiment One.

[0096] Compared with the prior art, the recycling container provided in this embodiment has the beneficial effects of the filtering barrel provided in Embodiment One, which will not be elaborated here one by one.

[0097] The above-mentioned recycling container is provided with a recycling cavity 4. The above-mentioned filtering barrel is detachably installed in the recycling cavity 4 through a connecting plate 2. Specifically, the connecting plate 2 is in sealing contact with the side wall of the recycling cavity 4. The barrel body 1 is located in the recycling cavity 4, and there is a gap between the bottom end surface of the barrel body 1 and the bottom wall of the recycling cavity 4 to ensure the solid-liquid separation effect in the recycling container.

[0098] The recycling container is provided with a fluid inlet 401 communicating with the recycling cavity 4. The recycling container is communicated with the cleaning component of the cleaning device through the fluid inlet 401. The dust-containing fluid absorbed by the cleaning component enters the recycling container through the fluid inlet 401.

[0099] A diversion pipe 41 is provided in the recycling cavity 4. One end of the diversion pipe 41 is communicated with the fluid inlet 401, and the other end of the diversion pipe 41 is communicated with the liquid inlet 101 to introduce all the dust-containing fluid entering the recycling container into the barrel body 1.

[0100] The pipe wall of the diversion pipe 41 is as close as possible to the cavity wall of the recycling cavity 4 to avoid the diversion pipe 41 crisscrossing in the recycling cavity 4, occupying the volume of the recycling cavity 4, and thus compressing the volume of the barrel body 1 and the liquid storage space.

[0101] In this embodiment, the fluid inlet 401 is located on the bottom wall of the recycling cavity 4. The diversion pipe 41 includes a first elbow 411, a second elbow 412, a longitudinal pipe 413, and a transverse pipe 414 connected in sequence. The first elbow 411 is connected to the fluid inlet 401. After two bending transitions through the first elbow 411 and the second elbow 412, the longitudinal pipe 413 can be close to the side wall of the recycling cavity. The transverse pipe 414 is perpendicularly connected to the longitudinal pipe 413, and the outlet end of the transverse pipe 414 is connected to the liquid inlet 101.

[0102] After the first elbow 411 and the second elbow 412 are connected together, they form a shape similar to an "S" to achieve the purpose of making the longitudinal pipe 413 close to the side wall of the recycling cavity 4. Specifically, both the first elbow 411 and the second elbow 412 are arc-shaped pipes with one bend. The arc of the first elbow 411 faces the adjacent cavity wall of the recycling cavity 4, and the arc of the second elbow 412 faces the internal space of the recycling cavity 4.

[0103] In some embodiments, the first elbow 411 and the second elbow 412 can be combined into a bent pipe with two bending degrees, as long as it can make the longitudinal pipe 413 close to the side wall of the recovery cavity. However, the production cost of such a bent pipe is relatively high, and the assembly difficulty is relatively large.

[0104] The first elbow 411 and the second elbow 412 of the diversion pipe 41 of the present invention make the longitudinal pipe 413 close to the side wall of the recovery cavity 4, which can effectively save the volume of the recovery cavity 4, avoid the crisscross of pipelines in the recovery cavity 4, and facilitate the cleaning of the recovery container. In addition, this segmented design of the diversion pipe 41 also makes its assembly more convenient and reduces the production cost. Moreover, the first elbow 411 and the second elbow 412 make a part of the pipeline of the diversion pipe 41 a bent pipeline, which can slow down the flow rate of the dusty fluid in the diversion pipe 41, thereby prolonging the flow time of the dusty fluid in the diversion pipe 41, increasing the filtration time of the filtration barrel for the dusty fluid entering the barrel body 1, avoiding a large amount of the dusty fluid pouring into the barrel body 1 in a short time, causing too much filtration pressure on the filtration barrel, and ensuring that the filtration barrel has a stable and good filtration effect.

[0105] It should be noted that there is a gap between the side wall of the barrel body 1 and the side wall of the recovery cavity 4, and this gap is large enough for the diversion pipe 41 to pass through.

[0106] The recovery container further includes a filtration part 5, which is located above the diversion part 3 and filters and removes dust from the dusty air flow led out by the diversion part 3. Specifically, the filtration part 5 is located above the connection frame 34, and the dusty air flow in the connection frame 34 is led out of the recovery container after being filtered by the filtration part 5.

[0107] The filtration part 5 includes a filter hepa and a dehumidifying agent to remove dust and water molecules in the dusty gas, make the air flow discharged from the recovery container dry and clean, and avoid corroding the downstream components of the recovery container.

[0108] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
