[0077] Example 1

[0078] This embodiment provides a recycling container, such as Figures 1 to 18 Shown, including:

[0079] The recovery chamber is provided with a fluid inlet 501 to allow dust-laden fluid to enter the recovery chamber;

[0080] The filter barrel 1 is installed in the recovery chamber to separate the dust-laden fluid entering the recovery chamber from solid and liquid. The filter barrel 1 includes a connecting portion 11 and a rotating portion 12. The rotating portion 12 is located below the connecting portion 11 and is rotatably connected to the connecting portion 11 so that the rotating portion 12 can rotate around the center line of the filter barrel 1.

[0081] The connecting portion 11 is provided with a liquid inlet 101 for the dust-laden fluid to enter the filter barrel 1;

[0082] The rotating part 12 is provided with a plurality of filter holes 121 , which are distributed on the side wall and / or the bottom wall of the rotating part 12 , so that liquid in the dust-laden liquid entering the filter barrel 1 can flow out through the filter holes 121 .

[0083] It should be noted that the above-mentioned dust-laden fluid includes solid debris (such as hair, debris, etc.), waste liquid and dust-laden airflow, etc. The substances absorbed from the ground into the recovery container by the cleaning components of the floor cleaning equipment (such as floor brushes, roller brushes, etc.) are all included in the dust-laden fluid.

[0084] Compared with the prior art, the recovery container of the present invention is provided with a filter barrel 1, so that the dust-laden fluid entering the recovery container can be separated into solid and liquid, that is, the solid debris in the dust-laden fluid is stored in the filter barrel 1, and the liquid in the dust-laden fluid is filtered by the filter barrel 1 and stored in the liquid storage space between the recovery cavity and the filter barrel 1. In this way, the solid debris and waste liquid in the dust-laden fluid entering the recovery container are stored in separate areas, which not only facilitates the cleaning of the recovery container, but also avoids the breeding of bacteria caused by the mixing of solid debris and waste liquid.

[0085] In addition, the rotating part 12 can rotate relative to the connecting part 11. Driven by external force, the rotating part 12 generates centrifugal force when it rotates axially, so that the waste liquid in the dust-containing fluid is thrown out from the filter hole 121 under the action of centrifugal force and enters the liquid storage space, so as to accelerate the filtering effect of the filter barrel 1 and accelerate the solid-liquid separation process of the recovery container.

[0086] The recovery container further includes a drive assembly 2 , a fluid pipeline 3 , an upper end cover 4 and a box body 5 .

[0087] The upper end cover 4 is located above the box body 5, and the upper end cover 4 and the box body 5 jointly limit the recovery cavity. Specifically, the upper end cover 4 is provided on the box body 5, the fluid inlet 501 is opened on the box body 5, a part of the filter barrel 1 is connected to the upper end cover 4, and the remaining part of the filter barrel 1 is located in the box body 5.

[0088] The driving assembly 2 is installed in the recovery chamber and connected to the rotating part 12 to drive the rotating part 12 to rotate. Specifically, the driving assembly 2 is installed at the bottom of the box 5, below the filter barrel 1, and connected to the bottom of the rotating part 12.

[0089] The fluid conduit 3 is installed in the recovery chamber, and one end is connected to the fluid inlet 501 and the other end is connected to the liquid inlet 101 to guide the dust-laden fluid into the filter barrel 1. Specifically, the fluid conduit 3 is located in the box body 5.

[0090] The filter barrel 1 is connected to the upper end cover 4 via a connecting portion 11 , which is located above the rotating portion 12 . Therefore, the liquid inlet 101 is located above the filter holes 121 to ensure that all the filter holes 121 can filter solid debris.

[0091] The filter barrel 1 is also provided with an air outlet 102 for the gas in the dust-laden fluid to be discharged through the air outlet 102. Specifically, the air outlet 102 is located on the connecting portion 11, and preferably the air outlet 102 is opened on the top end surface of the connecting portion 11 to prevent solid debris in the filter barrel 1 from blocking the discharge of the dust-laden airflow.

[0092] In this embodiment, the connecting part 11 includes a connecting plate 111 and a connecting ring wall 112. The connecting plate 111 is arranged on the outside of the top of the connecting ring wall 112 and is connected to the upper end cover 4 through the connecting plate 111. The top end face of the connecting ring wall 112 is provided with an air outlet 102, and the side wall of the connecting ring wall 112 is provided with a liquid inlet 101. The bottom end of the connecting ring wall 112 is connected to the rotating part 12, and the connecting ring wall 112 and the side wall of the rotating part 12 together form the side wall of the filter barrel 1.

[0093] It should be noted that both ends (top and bottom) of the connecting ring wall 112 are open, that is, the mouth wall of the air outlet 102 is flush with the inner side wall of the connecting ring wall 112 .

[0094] In this embodiment, the filter holes 121 are formed on the sidewalls and bottom wall of the rotating portion 12, and the filter holes 121 on the sidewalls are evenly distributed on the sidewalls of the rotating portion 12. Since all the filter holes 121 are located below the liquid inlet 101, the waste liquid in the dust-laden fluid entering the filter barrel 1 is quickly expelled from the filter holes 121 under the action of gravity.

[0095] The shapes of all the filter holes 121 can be the same or different, and the sizes of the filter holes 121 can be the same or different. The manufacturer can design the shape and size of the filter holes 121 according to the shape and size of the filter barrel and the environment in which the filter barrel is used. Preferably, all the filter holes 121 have the same shape and size so that the filter barrel 1 has a stable filtering effect. The filter holes 121 are circular holes. Since holes of the same area are opened on the same area, the number of circular holes is the largest. The diameter of the filter hole 121 is d, 2mm≤d≤5mm, which ensures that the waste liquid has a faster seepage rate while ensuring that solid impurities are filtered out as much as possible. In this embodiment, d=3mm.

[0096] In this embodiment, the connecting ring wall 112 is a cylindrical barrel with both ends open, and the rotating part 12 is a cylindrical barrel with the top open. The bottom end of the connecting ring wall 112 is connected to the top end of the rotating part 12, and the center lines of the connecting ring wall 112 and the rotating part 12 are collinear and have the same radius to facilitate cleaning and installation of the filter barrel.

[0097] The bottom end of the connecting ring wall 112 is rotatably connected to the top end of the rotating part 12 (not shown in the accompanying drawings). Specifically, the bottom end of the connecting ring wall 112 is provided with an annular slide rail, and the top end of the rotating part 12 is provided with a pulley or sliding ball compatible with the annular slide rail, so that the rotating part 12 rotates relative to the connecting ring wall 112, and the rotating part 12 rotates around its center line under the drive of the driving assembly 2, so that the liquid in the dust-containing fluid in the rotating part 12 is quickly thrown out under the action of centrifugal force, so as to accelerate the solid-liquid separation speed of the filter barrel 1.

[0098] The connecting plate 111 is connected to the connecting ring wall 112 , and the connecting plate 111 is located above the liquid inlet 101 , so that the filter barrel 1 can be assembled into the recovery cavity without affecting the introduction of the dust-laden fluid.

[0099] Specifically, the connecting plate 111 is vertically connected to the connecting ring wall 112 so that the filter barrel 1 is vertically arranged in the recovery chamber, thereby improving the filtering effect of the filter barrel. The connecting plate 111 is supported by the upper end cover 4 upward and is supported by the connecting ring wall 112, the rotating part 12 and the gravity of the dust-containing fluid in the filter barrel 1 downward. The two forces are easily balanced, so that the filter barrel 1 is stably balanced in the recovery container and has a stable filtering effect. The connecting plate 111 is subjected to balanced force, so that the connection between it and the connecting ring wall 112 is firm and reliable.

[0100] In this embodiment, the connecting plate 111 is an annular plate, which is vertically arranged outside the top end of the side wall of the connecting ring wall 112, that is, the connecting plate 111 is arranged outside the air outlet 102. In some embodiments, there are multiple connecting plates 111, and these connecting plates 111 are vertically arranged outside the connecting ring wall 112.

[0101] To ensure that the dust-laden airflow in the filter barrel 1 is discharged as quickly as possible, an air guide platform 122 is provided in the rotating part 12. The air guide platform 122 is located at the bottom of the rotating part 12 and is opposite to the air outlet 102 to guide the dust-laden airflow to the air outlet 102 as quickly as possible.

[0102] Specifically, the bottom of the air guide platform 122 is connected to the bottom wall of the rotating part 12 , a gap is provided between the side walls of the air guide platform 122 and the side walls of the rotating part 12 , and the filter holes 121 of the bottom wall of the rotating part 12 are surrounded by the outside of the bottom of the air guide platform 122 .

[0103] In order to make the air guide platform 122 have a better guiding effect, the air guide platform 122 is in the shape of a cone, and gradually shrinks from the bottom to the top, that is, the side wall of the air guide platform 122 gradually slopes inward from bottom to top.

[0104] In this embodiment, the air guide platform 122 is shaped like a truncated cone, with the top end radius being smaller than the bottom end radius. The central axis of the air guide platform 122 is collinear with the central axis of the rotating portion 12, meaning that the air guide platform 122 is located at the bottom center of the rotating portion 12. Guided by the air guide platform 122, the dust-laden airflow within the filter barrel 1 spirals upward toward the air outlet 102, and then exits the filter barrel 1 through the air outlet 102.

[0105] A groove 123 is provided at a position corresponding to the air guide platform 122 on the lower end surface of the bottom wall of the rotating part 12. The groove 123 is adapted to the air guide platform 122. Without affecting the guiding function of the air guide platform 122, the weight of the air guide platform 122 can be reduced as much as possible, thereby reducing the weight of the filter barrel 1.

[0106] A portion of the driving assembly 2 is installed in the groove 123. Specifically, the driving assembly 2 includes a bracket 21, a rotating motor 22 and a rotating blade 23. The bracket 21 is connected to the housing 5. The rotating motor 22 is installed on the bracket 21. The rotating blade 23 is sleeved on the output shaft of the rotating motor 22. After the rotating motor 22 is started, the rotating blade 23 rotates with the output shaft.

[0107] The groove 123 is provided with a key portion 123a, and the rotating blade 23 is located in the groove 123 and is engaged with the key portion 123a, so that the rotating portion 12 can rotate along with the rotating blade 23. It should be noted that the shape of the key portion 123a is adapted to the shape of the rotating blade 23, so that the rotating blade 23 can be detachably engaged with the key portion 123a.

[0108] The driving assembly 2 is partially located in the groove 123, so that the driving assembly 2 does not affect the volume of the filter barrel 1 and occupies as little liquid storage space as possible. There is no need to increase the volume of the recovery container, and the components in the recovery container are arranged compactly and orderly.

[0109] In this embodiment, the bracket 21 is connected to the bottom wall of the box body 5, that is, the bracket 21 is connected to the bottom wall of the recovery chamber.

[0110] In order to improve the filtering effect of the filter barrel 1 and prevent the dust-laden airflow from forming turbulence in the filter barrel 1 and affecting the filtration of the dust-laden fluid, the filter barrel 1 also includes a flow guide 13. The flow guide 13 includes an exhaust pipe 131 and a cyclone portion 132. The cyclone portion 132 is arranged around the outside of the exhaust pipe 131. The exhaust pipe 131 is connected to the air outlet 102, and the cyclone portion 132 is connected to the liquid inlet 101. The dust-laden fluid enters the filter barrel 1 from the liquid inlet 101. Under the guidance of the cyclone portion 132 and the exhaust pipe 131, the waste liquid and solid debris quickly fall to the bottom of the filter barrel under the action of centrifugal force and gravity. The dust-laden airflow forms a cyclone in the filter barrel, and is then guided by the air guide platform 122 to converge to the center of the filter barrel and discharged from the exhaust pipe 131 through the air outlet 102.

[0111] The cyclone portion 132 includes a wind shield 132a and a spiral plate 132b, one end of the wind shield 132a is connected to one side of the liquid inlet 101, the other end of the wind shield 132a is tangent to the exhaust pipe 131, one end of the spiral plate 132b is connected to the top end face of the wind shield 132a, and the other end of the spiral plate 132b is connected to the bottom end face of the wind shield 132a, that is, the spiral plate 132b spirally extends downward from the top end face of the wind shield 132a to the bottom end face, the inner side wall of the spiral plate 132b is connected to the exhaust pipe 131, and the outer side wall of the spiral plate 132b is connected to the inner side wall of the connecting ring wall 112.

[0112] The windshield 132a is opposite to the liquid inlet 101, and the projection of the windshield 132a toward the liquid inlet 101 can completely cover the liquid inlet 101. The angle α between the windshield 132a and the liquid inlet 101 is less than 90°, so that the dust-laden fluid entering from the liquid inlet 101 is first blocked by the windshield 132a, eliminating the inertia of most of the waste liquid and solid debris, so that these waste liquid and solid debris fall as quickly as possible under the action of gravity, and the dust-laden airflow is 2b and the exhaust pipe 131, a spiral downward cyclone is formed in the filter barrel, and then, under the guidance of the air guide platform 122, the cyclone spirals upward and converges to the center and is guided out of the filter barrel 1 through the exhaust pipe 131. Except for most of the waste liquid and solid debris that are blocked by the wind shield 132a and fall down, the remaining small part of the waste liquid and solid debris is carried by the dust-laden airflow to perform spiral motion. This part of the waste liquid and solid debris eventually falls to the bottom of the filter barrel under the action of the centrifugal force of the cyclone and its own gravity.

[0113] In order to ensure that the wind shield 132a has a good blocking and guiding effect without affecting the dust-laden fluid from entering the filter barrel 1, 30°≤α≤70°. In this embodiment, α=50°.

[0114] In this embodiment, the wind shield 132a is a rectangular plate, the liquid inlet 101 is similar to a rectangle (the liquid inlet is rectangular when the connecting ring wall is flattened), the height of the wind shield 132a (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 132b is the same as the width of the wind shield 132a (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 131).

[0115] The exhaust pipe 131 is a cylindrical tube with an air inlet 103 and an air outlet 104 at both ends. A fluid channel for air flow is provided between the air inlet 103 and the air outlet 104. The air inlet 103 is located in the filter barrel 1 (in this embodiment, the air inlet 103 is located in the rotating part 12) and is opposite to the air guide platform 122. The air outlet 104 is connected to the air outlet 102, so that all the dust-laden airflow entering the exhaust pipe 131 is guided out of the filter barrel 1 through the air outlet 102.

[0116] To quickly direct dust-laden gas into the exhaust pipe 131, an air collecting hood 133 is provided at the bottom of the exhaust pipe 131. The air collecting hood 133 has a conical ring wall that gradually extends outward from top to bottom. The air collecting hood 133 faces the air guide platform 122, allowing the gas to quickly gather into the exhaust pipe 131. Specifically, the air collecting hood 133 is trumpet-shaped and is located at the bottom end of the exhaust pipe 131, surrounding the outside of the air inlet 103, with the trumpet opening facing the air guide platform 122.

[0117] A filter 134 is provided at the bottom of the air collecting hood 133 . The gas must be filtered through the filter 134 before entering the air collecting hood 133 to prevent light solid debris (such as paper scraps, hair, etc.) in the filter barrel from being introduced into the exhaust pipe 131 along with the air flow.

[0118] It should be noted that the lower end of the air collecting cover 133 is opposite to the air guide platform 122 and has a certain distance therefrom, so that the air flow can be smoothly introduced into the exhaust pipe 131 .

[0119] In this embodiment, the air collecting cover 133 can be detachably mounted on the bottom of the exhaust pipe, and the filter 134 can be detachably mounted on the air collecting cover 133 so as to facilitate the recovery of the container for cleaning and maintenance.

[0120] The cyclone portion 132 is sealed to the inner wall of the connecting ring wall 112 to ensure that the airflow in the filter barrel 1 can only be discharged through the exhaust pipe 131 .

[0121] The guide member 13 is detachably mounted in the connecting portion 11 to clean impurities in the filter barrel 1. In this embodiment, the guide member 13 is detachably mounted on the top of the connecting ring wall 112. The cyclone portion 132 is located in the connecting ring wall 112 and is in sealing contact with the inner wall of the connecting ring wall 112.

[0122] To enhance the connection strength between the deflector 13 and the connecting portion 11, hooks 135 are provided on both sides of the deflector 13. The top end surface of the sidewall of the connecting ring wall 112 is provided with a groove 112a adapted to fit the hooks 135. The hooks 135 are snapped into the groove 112a to achieve a detachable connection between the deflector 13 and the connecting portion 11. In this embodiment, the hooks 135 are located above the cyclone portion 132.

[0123] The guide member 13 is also provided with a connecting frame 136, which is located above the cyclone part 132 and the exhaust pipe 131, and is surrounded by the outside of the air outlet 104 so that the dust-laden airflow derived from the air outlet 104 can all enter the connecting frame 136. The connecting frame 136 is used to guide the dust-laden airflow and connect with other components.

[0124] The bottom end surface of the connection frame 136 is sealed with the cyclone portion 132 and the top of the exhaust pipe 131 to prevent the dust-laden airflow from leaking out.

[0125] In this embodiment, the connection frame 136 is a rectangular frame.

[0126] The connecting plate 111 is detachably connected to the bottom of the upper end cover 4 to facilitate installation, disassembly, cleaning and maintenance of the filter barrel 1.

[0127] The upper end cover 4 is provided with an exhaust channel, which is provided with a channel inlet 401 and a channel outlet. The channel inlet 401 is connected to the air outlet 102. The dust-laden airflow discharged from the filter barrel 1 from the air outlet 102 is discharged from the upper end cover 4 through the exhaust channel.

[0128] Specifically, the channel inlet 401 is located at the bottom end surface of the upper end cover 4, and the channel outlet is located at the top end surface of the upper end cover 4. The channel inlet 401 is opposite to and connected to the connecting frame 136, so that all the dust-laden airflow in the filter barrel 1 is introduced into the exhaust channel.

[0129] A filter unit 41 is provided in the exhaust passage, and the filter unit 41 is sealed to the side wall of the exhaust passage, so that the dust-laden airflow entering the exhaust passage is removed by the filter unit 41 for dust removal and dehumidification before being discharged from the recovery container.

[0130] Filter unit 41 corresponds to air outlet 102 and filters the dust-laden airflow exiting air outlet 102 before discharging the filtered air into a recovery container. Specifically, filter unit 41 includes a HEPA filter and a dehumidifier to remove dust and water from the dust-laden air, ensuring that the airflow exiting the recovery container is dry and clean, preventing corrosion on downstream components of the recovery container.

[0131] In this embodiment, a detachable cover of the filter portion 41 is provided at the channel outlet for easy installation, disassembly, cleaning and maintenance.

[0132] The upper end cover 4 and the box body 5 are detachably connected, and a sealing ring 42 is provided at the connection. The sealing ring 42 can not only enhance the connection strength between the upper end cover 4 and the box body 5, but also realize a sealed connection between the upper end cover 4 and the box body 5, so that the airflow entering the recovery chamber can only be discharged through the exhaust channel.

[0133] In this embodiment, an assembly ring 43 is provided at the bottom of the upper end cover 4, and a sealing ring 42 is sleeved on the outside of the assembly ring 43. The shape of the assembly ring 43 is adapted to the shape of the box body 5. The assembly ring 43 is sleeved with the sealing ring 42 and can be inserted into the box body 5. The upper end cover 4 is interference-connected (or tightly-fitted) with the box body 5 through the sealing ring 42, thereby realizing a sealed connection between the upper end cover 4 and the side wall of the box body 5.

[0134] Furthermore, the outer wall of the assembly ring 43 is provided with a thread, and the inner wall of the sealing ring 42 is provided with a thread adapted to the thread of the assembly ring 43 to enhance the connection performance between the upper end cover 4 and the box body 5. In addition, the outer wall of the sealing ring 42 is provided with a thread to facilitate the disassembly of the upper end cover 4 and the box body 5.

[0135] It should be noted that the assembly ring 43 is arranged around the outside of the connecting plate 111 to prevent the assembly ring 43 from interfering with the assembly of the filter barrel 1.

[0136] The upper end cover 4 also includes a pressing member 44, and the recovery container is detachably installed in the cleaning device through the pressing member 44. Specifically, the button of the pressing member 44 is located on the side wall of the upper end cover 4.

[0137] The connecting plate 111 is connected to the upper end cover 4, the connecting ring wall 112 and the rotating part 12 are located in the box body 5, and a gap is provided between the side wall of the filter barrel (i.e., the side wall of the connecting ring wall and the rotating part 12) and the side wall of the box body 5, as well as a gap is provided between the bottom wall of the filter barrel (i.e., the bottom wall of the rotating part 12) and the bottom wall of the box body 5 to ensure the solid-liquid separation effect in the recovery container, and the gap between the side wall and the bottom wall is sufficient for the fluid pipe 3 to pass through, so as not to affect the circulation of the dust-containing fluid in the fluid pipe 3.

[0138] The ratio of the sum of the heights of the connecting ring wall 112 and the rotating portion 12 to the height of the housing 5 is greater than or equal to 1:2 and less than or equal to 4:5, to ensure that the recovery container has both good solid-liquid separation and sufficient volume for storing waste liquid. In this embodiment, the ratio of the sum of the heights of the connecting ring wall 112 and the rotating portion 12 to the height of the housing 5 is 3:4.

[0139] The fluid conduit 3 is located in the box body 5 , and one end of the fluid conduit 3 is connected to the fluid inlet 501 , and the other end is connected to the liquid inlet 101 , so as to guide all the dust-laden fluid entering the recovery container into the filter barrel 1 .

[0140] The wall of the fluid pipeline 3 is as close as possible to the wall of the recovery cavity (i.e., the inner wall of the box body 5) to avoid the fluid pipeline 3 crisscrossing in the recovery cavity, occupying the volume of the recovery cavity, and then compressing the volume of the filter barrel and the liquid storage space.

[0141] In this embodiment, the fluid inlet 501 is located on the bottom wall of the box body 5, and the fluid pipeline 3 includes a first bend pipe 31, a second bend pipe 32, a longitudinal pipe 33 and a transverse pipe 34 connected in sequence. The first bend pipe 31 is connected to the fluid inlet 501. After two bending transitions of the first bend pipe 31 and the second bend pipe 32, the longitudinal pipe 33 can be close to the side wall of the recovery cavity. The transverse pipe 34 is vertically connected to the longitudinal pipe 33, and the outlet end of the transverse pipe 34 is connected to the liquid inlet 101.

[0142] The first curved tube 31 and the second curved tube 32 are connected together to form an S-shaped structure, which allows the longitudinal tube 33 to be closely attached to the side wall of the recovery chamber (i.e., the inner wall of the housing 5). Specifically, the first curved tube 31 and the second curved tube 32 are both curved tubes with a curvature. The first curved tube 31 is curved toward the adjacent recovery chamber wall, while the second curved tube 32 is curved toward the interior of the recovery chamber.

[0143] In some embodiments, the first bend 31 and the second bend 32 can be combined into a curved tube with two curvatures, as long as the longitudinal tube 33 can be close to the side wall of the recovery cavity. However, the production cost of this curved tube is high and the assembly is difficult.

[0144] The first bend 31 and the second bend 32 of the fluid pipeline 3 of the present invention make the longitudinal tube 33 close to the side wall of the recovery chamber, which can effectively save the volume of the recovery chamber, avoid the criss-crossing of the pipes in the recovery chamber, and facilitate the cleaning of the recovery container; in addition, the segmented design of the fluid pipeline 3 also makes its assembly more convenient and reduces production costs; furthermore, the first bend 31 and the second bend 32 make a part of the fluid pipeline 3 a curved pipeline, which can slow down the flow rate of the dust-laden fluid in the fluid pipeline 3, and thus prolong the flow time of the dust-laden fluid in the fluid pipeline 3, so as to increase the filtering time of the filter barrel for the dust-laden fluid entering the filter barrel 1, and avoid the dust-laden fluid from pouring into the filter barrel 1 in a short period of time, causing the filtering pressure of the filter barrel to be too high, so as to ensure that the filter barrel has a stable and good filtering effect.

[0145] In this embodiment, the upper end cover 4 is flush with the outer side wall of the box body 5 to facilitate the transfer of the recovery container.

[0146] In order to facilitate the removal and placement of the mobile recycling container, the recycling container further includes a handle 6. Specifically, the handle 6 is located on the outside of the box body 5, and the handle 6 and the button of the pressing member 44 are located on the same side of the recycling container.
