Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a recycling bin and a wet cleaning device. Background Technology

[0002] A typical wet cleaning system's dirt recovery system includes a suction motor and a recovery tank. The recovery tank, which contains a riser, collects dirt as it enters the tank. To improve gas-liquid separation efficiency, a gas-liquid separator is usually added inside the recovery tank. This separator is typically installed on the riser. Fluid flowing from the riser's outlet undergoes gas-liquid separation in the separator; the liquid is stored in the recovery tank, while the gas exits.

[0003] When cleaning the wastewater tank, users need to manually remove the gas-liquid separator from the riser and then clean the inside of the tank and the gas-liquid separator, which is quite troublesome. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, this invention provides a recycling bin with dual roller brushes, which can effectively clean both roller brushes simultaneously.

[0005] On the one hand, this utility model provides a recycling bin, including

[0006] A first enclosure, having defined a first space for containing dirt, and the first enclosure having defined a first opening.

[0007] A first cover is movably mounted on the first opening to close / open the first opening;

[0008] The first housing also includes a riser, which includes a liquid inlet, a liquid outlet, and a liquid inlet channel located between the liquid inlet and the liquid outlet. Fluid flows out from the liquid outlet and enters the first space.

[0009] A gas-liquid separator located near the liquid outlet is used to separate the gas and liquid from the fluid flowing out of the liquid outlet.

[0010] The gas-liquid separator is located on the first cover and can move together with the first cover.

[0011] Optionally, the gas-liquid separator includes a first baffle, the first baffle and a portion of the inner wall of the first cover together define a fifth space, and the liquid outlet is located within the fifth space.

[0012] Optionally, the gas-liquid separator is integrally formed with the first cover.

[0013] Optionally, the first baffle includes a plurality of baffles extending in a direction away from the inner wall, the plurality of baffles being spaced apart in the circumferential direction of the riser.

[0014] Optionally, it also includes an air outlet pipe, which includes an air inlet, an air outlet, and an air outlet channel located between the air inlet and the air outlet, with at least a portion of the first baffle located between the liquid outlet and the air inlet.

[0015] Optionally, the lowest point of the first baffle is lower than the lowest point of the air inlet in the vertical direction.

[0016] Optionally, the first housing and the first cover together define the air inlet.

[0017] Optionally, the projection of the air intake along the horizontal direction falls entirely on the first baffle.

[0018] Optionally, the first baffle is semi-annular, and the first baffle extends circumferentially along the riser.

[0019] On the other hand, this utility model also provides a wet cleaning device, which includes a body, characterized in that a suction motor for generating suction airflow is provided in the body.

[0020] The body defines an installation space for installing a recycling bin as described above.

[0021] Optionally, the wet cleaning equipment also includes a cleaning fluid tank for providing cleaning fluid, the cleaning fluid tank and the recycling tank being integrally formed.

[0022] This utility model provides a recycling bin and a wet cleaning device, comprising a first bin body and a first cover. The first bin body defines a first space for containing dirt and a first opening. The first cover is movably mounted on the first opening to close / open the first opening. The first bin body also includes a riser, which includes an inlet, an outlet, and an inlet channel located between the inlet and outlet, through which fluid flows from the outlet into the first space. A gas-liquid separator located near the outlet is used to separate the fluid flowing from the outlet into gas and liquid. The gas-liquid separator is disposed on the first cover and can move with the first cover. By placing the gas-liquid separator on the first cover, it is not necessary to remove the gas-liquid separator separately when cleaning the recycling bin; only the first cover needs to be opened. Similarly, when cleaning the gas-liquid separator, the user does not need to touch the gas-liquid separator by hand; only the first cover needs to be held. Furthermore, by placing the gas-liquid separator on the first cover, the height of the gas-liquid separator relative to the bottom of the first box can be effectively increased, thereby increasing the effective volume of the recovery box and improving the gas-liquid separation efficiency.

[0047] refer to Figure 1-3 The figure discloses a wet cleaning device 100, which can be a horizontal cleaning device, a vertical cleaning device, a handheld cleaning device, or a self-contained cleaning device. The wet cleaning device 100 generally includes a dirt recovery system and / or a cleaning fluid supply system. The dirt recovery system includes a suction motor 3 for generating a suction airflow, a suction pipe 31 for guiding the suction airflow, and a recovery tank 1 for recovering dirt. The cleaning fluid supply system provides cleaning fluid and includes a cleaning fluid pump and a cleaning fluid tank 2. The wet cleaning device 100 also includes an electrical control system, which includes circuit boards and other electrical components, and can control the operation and shutdown of the wet cleaning device 100. Since electrical control systems are very common in cleaning equipment, they will not be described in detail here. This application mainly describes the structure in detail.

[0048] refer to Figure 4-9 The suction line 31 includes a first line 311 located upstream of the suction motor 3 and a second line 312 located downstream of the suction motor 3. The dirt recovery system also includes a cooling line 32 for cooling the suction motor 3, which includes a third line 321 located upstream of the suction motor 3 and a fourth line 322 located downstream of the suction motor 3. Figure 8 As shown by the arrows in the diagram, the upper left arrow represents the cooling airflow, and the lower right arrow represents the suction airflow.

[0049] refer to Figure 5-9 The specific structure of one embodiment is described in detail below. The wet cleaning device 100 includes a body 4. The body 4 defines a receiving space 47 for accommodating a suction motor 3. The wet cleaning device 100 also includes a hose 5 (see reference). Figure 3 One end of the hose 5 is fluidly connected to the first conduit 311, and the other end of the hose 5 is fitted with a cleaning head 6. The body 4 also defines a storage space 41 for storing the hose 5. The body 4 also defines a first air outlet 42 connected to the second conduit 312 and a second air outlet 43 connected to the fourth conduit 322. The gas discharged from the first air outlet 42 and the second air outlet 43 enters the storage space 41.

[0050] refer to Figure 8The airflow from the first air outlet 42 and the second air outlet 43 is discharged into the storage space 41, preventing the airflow from blowing directly onto the ground and other surrounding objects. Both the first air outlet 42 and the second air outlet 43 are designed to face downwards. When the airflow blows directly onto the surface of the lower housing 45, it is deflected, resulting in a very low airflow velocity and minimal impact on surrounding objects. To further disperse the airflow, the first air outlet 42 and the second air outlet 43 are located on opposite sides of the wet cleaning device 100, or they can be spaced apart. This separate arrangement of the two air outlets effectively disperses the airflow and reduces noise.

[0051] refer to Figure 5-9 The body 4 includes an upper shell 44 and a lower shell 45, both of which are integrally molded. Both the upper and lower shells can be injection molded. The body 4 also includes a handle 49, which is located on the upper shell 44 and above the suction motor 3. A receiving space 47 is defined between the upper shell 44 and the lower shell 45 (see reference). Figure 9 The space 47 is used to install a water pump, piping, steam generator, and other components. As shown in the embodiment, the wet cleaning equipment 100 also includes a recovery tank 1 and a cleaning solution tank 2, and the upper housing 44 defines an installation space 48 (see reference). Figure 7 The recycling bin 1 and the cleaning fluid tank 2 are detachably installed in the installation space 48. In the embodiment shown in the figure, the lower housing 45 is generally elliptical and defines a storage space 41. This design can effectively reduce mold costs and assembly costs.

[0052] Continue to refer to Figure 5-9 The wet cleaning device 100 also includes a motor cover 46 disposed within the body 4, which, together with the lower housing 45, defines a motor mounting cavity. A suction motor 3 is disposed within the motor mounting cavity. The motor cover 46 and the lower housing 45 together define a fourth conduit 322. A motor inlet is located at the top of the motor cover 46, and a cooling air inlet is located on either the upper housing 44 or the lower housing 45. Under the action of the suction motor 3, external cooling airflow enters the body 4 through the cooling air inlet, then enters the motor through the motor inlet to cool its internal structure. The cooled airflow then exits through the rear outlet of the motor and flows along the fourth conduit 322 to the second outlet 43, where it is discharged into the storage space 41. The suction airflow generated by the suction motor 3 carries dirt from the cleaning head 6 into the first pipe 311. The fluid undergoes gas-liquid separation in the recovery box 1. After the gas-liquid separation, the airflow flows through the impeller of the suction motor 3 and enters the second pipe 312. Then it is discharged from the first air outlet 42 into the storage space 41.

[0053] refer to Figure 9 To balance the overall weight, the recovery tank 1 is positioned between the cleaning liquid tank 2 and the suction motor 3 along the length of the wet cleaning equipment 100. This design also simplifies the piping and reduces costs.

[0054] The following describes in detail the recycling bin 1 in one embodiment. The recycling bin 1 can be applied to robotic vacuum cleaners, upright, handheld, or horizontal wet cleaning devices. (See reference) Figure 10-20 The figure discloses a recycling bin 1, which includes a first body 12 and a first cover 14. The first body 12 defines a first space 11 for containing dirt, and the first body 12 defines a first opening 13. The first cover 14 is movably (pivoting or detaching, etc.) installed on the first opening 13 to close / open the first opening 13. Users can empty the dirt in the first space 11 through the first opening 13, and at the same time, they can clean the first space 11 through the first opening 13. The first body 12 also includes a riser 15, which includes a liquid inlet 151, a liquid outlet 152, and a liquid inlet channel 153 located between the liquid inlet 151 and the liquid outlet 152. Fluid carrying dirt flows sequentially through the liquid inlet 151, the liquid inlet channel 153, and the liquid outlet 152 under the action of the suction airflow generated by the suction motor 3, and then flows out from the liquid outlet 152 into the first space 11. The recycling bin 1 also includes a gas-liquid separator 16 located near the liquid outlet 152 for gas-liquid separation of the fluid flowing out of the liquid outlet 152. The separated contaminants are stored in the containment space 47, and the separated airflow flows out of the recycling bin 1. To guide the airflow out of the recycling bin 1, the first housing 12 also includes an exhaust pipe 17, which is in fluid communication with the suction motor 3. The exhaust pipe 17 includes a first portion 171 located in the first housing 12 and a second portion 172 located in the first cover 14 (see reference). Figure 15 and 17 The first part 171 and the second part 172 together define the air inlet 173 of the vent pipe 17. The vent pipe 17 also includes an air outlet 174 and an air outlet passage 175 located between the air inlet 173 and the air outlet 174. When the liquid level in the recovery tank 1 reaches the warning line, the use of the recovery tank 1 needs to be restricted. At this time, a float 18 is installed in the recovery tank 1. (Reference) Figure 13 , 14 16-18, the float 18 is movably disposed at the air outlet 17. When the liquid level in the first space 11 reaches a preset value, the float 18 can move with the liquid level to the air inlet 173 and close at least part of the air inlet 173. At this time, the airflow is cut off and will not flow through the recovery tank 1, and dirt will not be sucked into the recovery tank 1. In a specific embodiment, the riser 15 is inclined relative to the central axis X of the suction motor 3 (see reference). Figure 9 ).

[0055] refer to Figure 15-20 When emptying recycling bin 1, if the wastewater discharge path passes through air inlet 173, wastewater may enter air inlet 173 during the emptying process and then leak onto the ground or other places through air outlet 175 (see reference). Figure 19 Therefore, in the disclosed solution, the air inlet 173 is defined by the air outlet pipe 17 and the first cover 14. In this case, when sewage is discharged, the sewage discharge path does not flow through the air inlet 173, effectively preventing sewage from entering the air outlet channel 175 (see reference). Figure 20 To further ensure that sewage does not enter the venting channel 175, the upper edge of the first pipe body 179 is not lower than the upper edge of the first box body 12.

[0056] refer to Figure 15-19 The first part 171 includes a first tube 179 integrally formed with the first housing 12. The second part 172 includes a second baffle 178 extending from the inner wall 141 of the first cover 14. The second baffle 178 and the first tube 179 together define an air inlet 173. To improve sealing performance, a sealing structure (not shown) is provided between the first tube 179 and the second baffle 178, the sealing structure being configured to prevent airflow from passing through the contact area between the first tube 179 and the second baffle 178.

[0057] Continue to refer to Figure 13 and 14 The air outlet channel 175 includes a first channel 176 and a second channel 177 located downstream of the first channel 176, with the first channel 176 and the second channel 177 forming a certain angle. The first channel 176 is substantially parallel to the riser 15. The second channel 177 is substantially perpendicular to the surface to be cleaned. To effectively reduce costs, the outer wall of the air outlet pipe 17 forms part of the outer wall of the first housing 12.

[0058] refer to Figure 10-12 To improve separation efficiency, the recovery tank 1 also includes a gas-liquid separator 16 located near the liquid outlet 152 for gas-liquid separation of the fluid flowing out of the liquid outlet 152. To facilitate cleaning of the interior of the recovery tank 1 and the gas-liquid separator 16, and to reduce costs, the gas-liquid separator 16 is disposed on the inner wall 141 of the first cover 14 and can move with the first cover 14. The gas-liquid separator 16 is detachably installed on the first cover 14, and can also be integrally formed with the first cover 14.

[0059] Continue to refer to Figure 10-12The gas-liquid separator 16 includes a first baffle 162, which, together with the inner wall 141 of part of the first cover 14, defines a fifth space, within which the liquid outlet 152 is located. The first baffle 162 is semi-annular and extends circumferentially along the riser 15. This arrangement effectively utilizes space, as the higher the gas-liquid separator 16 is positioned above the liquid surface, the smaller the force exerted by the airflow on the liquid in the first space 11 (if the airflow is too strong, it will blow away some of the liquid, which will be sucked away by the suction motor 3, affecting the motor's operation), resulting in higher gas-liquid separation efficiency. Simultaneously, this design effectively reduces costs.

[0060] Continue to refer to Figure 10-12 To further improve separation efficiency, the first baffle 162 includes multiple baffles 163 extending away from the inner wall 141, spaced apart along the circumferential direction of the riser 15. Liquid gradually accumulates at the baffles 163, condensing into water droplets that fall directly into the first space 11, as these droplets are not easily carried by the airflow. The separated gas flows through the gaps between the baffles 163 to the air inlet 173. At least a portion of the first baffle 162 is located between the liquid outlet 152 and the air inlet 173. The lowest point of the first baffle 162 in the vertical direction is lower than the lowest point of the air inlet 173. In one specific embodiment, the projection of the horizontal air inlet 173 falls entirely on the first baffle 162 (see reference). Figure 14 At this point, the airflow first flows downwards at the gas-liquid separator 16, and then turns upwards towards the inlet 173. This prevents the airflow from flowing directly towards the inlet 173, thus improving the gas-liquid separation efficiency.

[0061] In one embodiment, the recycling bin 1 includes a first housing 12 and a first cover 14. The cleaning fluid tank 2 includes a second housing 24 and a second cover 23. To facilitate cleaning of the recycling bin 1 and simultaneously adding cleaning fluid to the cleaning fluid tank 2, the cleaning fluid tank 2 and the recycling bin 1 can be integrally formed into a storage tank 101. This allows for direct filling of the cleaning fluid after cleaning the recycling bin 1. The structural design of the recycling bin 1 within the storage tank 101 can adopt the structure described in the above embodiment, and will not be detailed here.

[0062] refer to Figure 10-20The liquid storage tank 101 includes a first space 11 for containing dirt and a second space 21 for containing cleaning fluid. The liquid storage tank 101 includes a body 102 and a cover 103. The body 102 is integrally formed from a first body 12 and a second body 24. The cover 104 may be integrally formed from a first cover 14 and a second cover 23. The body defines openings, including a first opening 13 communicating with the first space 11 and a second opening 22 communicating with the second space 21. The cover is movably mounted on the openings to close / open the first opening 13 and the second opening 22. The body also includes a riser 15, which includes an inlet 151, an outlet 152, and an inlet channel 153 located between the inlet 151 and the outlet 152. Fluid flows out from the outlet 152 and enters the containing space 47. The liquid storage tank 101 includes a gas-liquid separator 16 located near the liquid outlet 152 for gas-liquid separation of the fluid flowing out of the liquid outlet 152. The gas-liquid separator 16 is disposed on the inner wall 141 of the cover and can move with the cover.

[0063] Continue to refer to Figure 10-20 The housing 102 includes an outer shell and a first partition 104 for dividing the outer shell into a first space 11 and a second space 21 (see reference). Figure 15 The first partition plate 104 and the body of the riser 15 overlap. The liquid storage tank 101 also includes an air outlet pipe 17, which includes an air inlet 173, an air outlet 174, and an air outlet channel 175 located between the air inlet 173 and the air outlet 174. The outer shell and the body of the air outlet pipe 17 overlap. An upper baffle 25 is provided at the second opening 22, and an injection port 26 is provided on the upper baffle 25 near the handle 121. When the user cleans the liquid storage tank 101, especially when emptying the dirt in the recovery tank 1, the upper baffle 25 can block some of the liquid from flowing out of the cleaning liquid tank 2. The user can add cleaning liquid into the second space 21 of the injection port 26. A second partition plate corresponding to the first partition plate 104 is provided on the cover, and the second partition plate divides the space defined by the cover into a third space 161 and a fourth space (see reference). Figure 12 The liquid storage tank 101 also includes a gas-liquid separator 16, which is disposed in the third space 161 and is integrally formed with the cover. For easy access, the tank body also includes a handle 121, and the second space 21 is located between the first space 11 and the handle 121. The riser 15 is located between the handle 121 and the vent pipe.
