Figure 13 for Figure 12 Enlarged view of the structure of region A in the middle. (Reference) Figure 1-3 , Figure 1 A cleaning system 100 is disclosed, comprising a host 101 and a base station 102 for docking with the host 101. The host 101 is used to clean the surface to be cleaned. (Reference) Figure 2 and 3 The main unit 101 generally includes a body 10 and floor brushes 30 with handles 20 connected to both ends of the body 10. The main unit 101 may also include a dirt recovery system and a cleaning fluid supply system. The dirt recovery system generally includes a suction motor for generating suction airflow and a recovery tank 1. The suction airflow is used to recover dirt into the recovery tank 1 for gas-liquid separation and / or solid-liquid separation. The cleaning fluid supply system generally includes a cleaning fluid tank and a water pump, which supplies cleaning fluid to the sample or surface to be cleaned. The water pump can also be replaced by other commonly used power equipment, which will not be detailed here.

[0041] refer to Figure 4-13 This application provides a recycling bin 1, which includes a shell and a gas-liquid separator. The shell defines a receiving space for containing dirt. After the gas carrying dirt enters the recycling bin 1, the liquid separated by the gas-liquid separator is stored inside the recycling bin 1. The gas flows from the opening of the recycling bin 1 to the suction motor. The shell also defines an opening for emptying the dirt. The gas-liquid separator is disposed within the receiving space. The recycling bin 1 also includes a liquid inlet pipe 17, which guides dirt from the outside into the recycling bin 1. The liquid inlet pipe 17 is generally disposed within the receiving space of the recycling bin 1. Of course, part or all of the liquid inlet pipe 17 can also be disposed outside the recycling bin 1. The gas-liquid separator is disposed at the outlet of the liquid inlet pipe 17. To prevent the liquid inside the recycling bin 1 from easily splashing when the recycling bin 1 is in a horizontal position, this application makes some improvements to the gas-liquid separator:

[0042] refer to Figure 8-13 The gas-liquid separator includes a U-shaped baffle 161 and an arc-shaped guide plate 162 disposed at one end of the U-shaped baffle 161. The U-shaped baffle 161 surrounds the outer periphery of the liquid inlet pipe 17 and extends along the axial direction of the liquid inlet pipe 17; wherein, along the axial direction of the liquid inlet pipe 17 ( Figure 8In the diagram, the Z direction represents the height of the U-shaped baffle 161, the X direction represents the length of the U-shaped baffle 161, and the Y direction represents the width. The U-shaped baffle 161, with its U-shaped cross-section, defines an elongated opening. An arc-shaped guide plate 162 is disposed at one end of the U-shaped baffle 161 along its length. Specifically, the arc-shaped guide plate 162 includes a closed section 163 and an open section 164. The closed section 163 is used to close the upper end of the arc-shaped guide plate 162, and the open section 164 is disposed on the side of the opening 169 of the U-shaped baffle. The open section 164 is inclined relative to the opening 169 of the U-shaped baffle, that is, along the height direction of the U-shaped baffle 161, from top to bottom, the distance between the open section 164 and the opening 169 of the U-shaped baffle gradually increases, so that airflow can exit the U-shaped baffle 161 from this point. Furthermore, the arc-shaped guide plate 162 is provided with multiple guide channels 165, which are used to guide the fluid flowing out from the outlet of the liquid inlet pipe 17. Both the closed section 163 and the open section 164 have guide channels 165, which are connected to each other. The function of the guide channels 165 is to disperse the large amount of liquid flowing out from the outlet of the liquid inlet pipe 17, so that the liquid can quickly leave the gas-liquid separator in the form of water droplets along the guide channels 165 and then fall into the bottom of the recovery tank 1. This avoids a large amount of water vapor remaining between the U-shaped baffle 161 and the arc-shaped guide plate 162, preventing it from being sucked into the motor along with the gas. Especially when the recovery tank 1 is in a horizontal state (the body 10 is in a flat state), the guide channels 165 can effectively guide the liquid to a position away from the connecting port 168. In this way, it can effectively avoid the generation of a large amount of water splashes due to turbulent airflow at this point. The closed section 163 and the open section 164 can be integrally formed, and the guide channel 165 is formed on top of it at the same time. Multiple guide channels 165 can be arranged in parallel, and the entire arc-shaped guide plate 162 is wavy. The guide channel 165 can also gradually increase or decrease in size.

[0043] refer to Figure 6-11 The recycling bin 1 also includes a mounting bracket 15, which is detachably mounted at the opening. The mounting bracket 15 defines an installation space for installing a HEPA filter 151, wherein the HEPA filter 151 and the U-shaped baffle 161 are located on opposite sides of the closed section 163. That is, when the recycling bin 1 is upright, the HEPA filter 151 is positioned directly above the gas-liquid separator.

[0044] refer to Figure 6-11The mounting bracket 15 also defines a connecting port 168 that connects the receiving space and the installation space. The connecting port 168 and the open section 164 are located on opposite sides of the U-shaped baffle 161 along the width direction. When the main unit 101 is in the flat position, the connecting port 168 is located above the arc-shaped guide plate 162. That is, the opening 169 of the U-shaped baffle and the connecting port 168 are located on opposite sides of the liquid inlet pipe 17. In this way, after the liquid-carrying airflow flows out from the outlet of the liquid inlet pipe 17, under the guiding action of the arc-shaped guide plate 162, most of the liquid will flow along the guide groove 165 to the bottom of the recovery tank 1, while the gas will separate from the liquid, flow upward to the connecting port 168, and then flow out of the recovery tank 1 after passing through the filter HEPA 151. The air outlet is not provided between the guide grooves 165 of the arc-shaped guide plate 162 as in the structure described in the prior art because it can effectively prevent some airflow from blowing the liquid at this point and generating water splashes (i.e., water churning), thereby reducing the amount of water vapor being drawn into the suction motor.

[0045] refer to Figure 8 It also includes conductive detectors 152 arranged on both sides of the U-shaped baffle 161 along its length. The conductive detectors 152 are arranged substantially parallel to the liquid inlet pipe 17. The function of the conductive detectors 152 is to issue an alarm signal when the liquid surface is connected to both conductive detectors 152, and at the same time, the suction motor stops, which can prevent a large amount of liquid from being sucked into the motor.

[0046] To further ensure normal operation of the recycling bin 1 when it is in a horizontal position, an anti-backflow structure is provided below the U-shaped baffle 161. The anti-backflow structure includes a flow channel 13 and an anti-backflow component 12 disposed at the flow channel 13. The anti-backflow component 12 is configured to allow liquid flowing from the inlet pipe 17 to flow through the flow channel 13 into the area below the anti-backflow structure, and is configured to prevent at least part of the liquid below the anti-backflow component 12 from flowing back through the flow channel 13 to the area above the anti-backflow component 12. Especially when the recycling bin 1 is in a horizontal position, this effectively prevents the liquid on the left side of the figure from flowing back to the location of the arc-shaped guide plate 162 on the right side. The less water accumulates at the location of the arc-shaped guide plate 162, the less likely it is to cause water splashing, and the less water vapor is carried by the airflow to the suction motor, effectively extending the service life of the suction motor and the HEPA filter 151.

[0047] refer to Figure 11-13To achieve solid-liquid separation of waste, the anti-backflow structure includes a tray 166, which defines a receiving groove containing a filter screen 14 for solid-liquid separation of the waste. The solid waste after solid-liquid separation can be held above the filter screen 14. Furthermore, the filter screen 14 is pivotable relative to the anti-backflow component 12 to remove solid waste deposited on it. When the user removes the anti-backflow structure for cleaning, the filter screen 14 can be rotated to remove the solid waste deposited on it, and the waste on the tray 166 can also be cleaned. Furthermore, to prevent liquid backflow into the area where the arc-shaped guide plate 162 is located, at least a portion of the outer periphery of the tray 166 is in sealed contact with the inner wall of the recycling bin 1. To achieve this seal, a partial sealing gasket can be provided on the outer periphery of the tray 166; the sealing gasket can be made of rubber.

[0048] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
