The specific meaning of the terms in this application can be understood by those of ordinary skill in the art in a specific context.

Referring to fig. 1 and 2, the present application discloses a surface cleaning apparatus 101 comprising a body 10 and a handle 20 and a floor brush 30 at both ends of the body 10, respectively. The surface cleaning apparatus 101 generally comprises a cleaning liquid supply system comprising a cleaning liquid tank 3 for spraying a cleaning liquid onto a wiping part and/or a surface to be cleaned. The apparatus further comprises a soil recycling system, which generally comprises a recycling bin 1 and a suction motor for generating a suction air flow for recycling the soil from the surface to be cleaned into the recycling bin 1. To ensure that the recovery tank 1 can still be used when the surface cleaning apparatus 101 is in a lying state, and that no substantial liquid in the recovery tank 1 is sucked into the suction motor during use. The structure of the recovery box 1 is improved to a certain extent.

Referring to fig. 3 to 17, the recovery tank 1 includes a housing 11, the housing 11 defining a receiving space for receiving the dirt, the receiving space including a first space 111 and a second space 112 located below the first space 111, the housing 11 further defining an opening for dumping the dirt. The recovery tank 1 comprises a liquid inlet pipe 17, and dirt enters the accommodating space of the recovery tank 1 through the liquid inlet pipe 17. The recovery tank 1 further includes a backflow preventing structure (refer to fig. 4 and 5) provided in the housing 11. Generally, the backflow preventing structure is disposed between the first space 111 and the second space 112. When the housing 11 is upright, the space above the backflow preventing structure is the first space 111, and the space below the backflow preventing structure is the second space 112. The backflow preventing structure includes a flow passage 13 and a backflow preventing member 12 provided at the flow passage 13. The flow passage 13 is used to communicate the first space 111 and the second space 112. The dirt entering from the liquid inlet pipe 17 is subjected to gas-liquid separation in the first space 111, and the liquid and/or solid after the gas-liquid separation can pass from the circulation channel 13 into the second space 112, and the second space 112 is generally used for storing the dirt. In order to prevent the recovery tank 1 from returning a large amount of liquid in the second space 112 to the space when in a lying or substantially lying state, a large amount of water is turned up in the first space 111 to cause a large amount of water vapor to be brought into the suction motor by the suction air flow, and therefore, the backflow preventing member 12 has the following configuration: the backflow prevention member 12 is configured to allow the liquid in the first space 111 to flow into the second space 112 through the flow passage 13, and is configured to prevent at least part of the liquid in the second space 112 from flowing back into the first space 111 through the flow passage 13. In this way, the liquid can be effectively prevented from flowing back into the first space 111 when the recovery tank 1 is in the lying position. Specifically, there are many structures that can realize the functions possessed by the backflow preventing member 12, for example: a one-way valve may be provided in the flow channel 13 or the flow channel 13 may be opened or closed by movement of a ball (here and following "closing the flow channel 13" does not mean a complete seal, but rather prevents a substantial part of the fluid from flowing from the second space 112 to the first space 111), and other realizable ways that are conceivable by the skilled person are not described here again. Referring to the drawings, in order to make the structure simpler, the flow passage 13 is less likely to be blocked by relatively large dirt, and the backflow preventing member 12 includes a baffle plate 121, and the baffle plate 121 is pivotably disposed at the flow passage 13. The baffle 121 may be arranged so as not to close the flow channel 13 when standing upright, for example, by arranging the baffle 121 at the flow channel 13 with a rotating shaft, the baffle 121 may be in an open state under the influence of gravity. The baffle 121 may be gradually moved closer to the flow channel 13 when the recovery tank 1 is in an inclined state, and the baffle 121 substantially closes the flow channel 13 when the recovery tank 1 is lying down, especially in case of liquid in the second space 112, the liquid in the second space 112 may exert a pressure on the baffle 121 to further close the flow channel 13. Of course, the baffle 121 may be configured to always keep the circulation channel 13 in a closed state without an external force, and when the liquid exists in the first space 111, the baffle 121 may be opened by the gravity of the liquid so as to flow into the second space 112. Specifically, the baffle 121 may be a baffle made of a piece of rubber material, and may be automatically reset by means of elasticity of rubber.

Referring to fig. 12-17, in one specific embodiment, the backflow preventing member 12 includes a support plate 122, the support plate 122 defines a receiving slot 123, the support plate 122 defines a flow channel 13, and a switch structure is disposed at the flow channel 13 and configured to close the flow channel 13 or reduce a flow area of the flow channel 13. The switch structure may be a baffle 121 as described above, a check valve, or the like, and will not be described in detail herein. The emphasis here is on the tray 122, which tray 122 may function as a support switch structure if it is. The supporting plate 122 may also be provided with a filter screen 14, where the filter screen 14 is disposed in the first space 111 for solid-liquid separation, and the filter screen 14 is located upstream of the backflow preventing component 12. Further, filter 14 may also be disposed within receiving slot 123. In this way, some relatively large particles do not easily enter the second space 112. Further, filter screen 14 may be pivotable relative to backflow prevention member 12 for cleaning solid dirt deposited on filter screen 14.

In order to further prevent the liquid in the second space 112 from flowing back into the first space 111, at least part of the outer periphery of the pallet 122 is in sealing contact with the inner wall of the recovery tank 1. The periphery of the supporting plate 122 can be provided with one or half circle of sealing gasket 18, the sealing gasket 18 is in interference fit with the inner wall of the recovery tank 1, liquid backflow is effectively prevented, and the volume of the sewage tank can be used in a percentage, so that when the sewage tank is in a horizontal position, the periphery of the lower half part of the supporting plate 122 is in sealing contact with the inner wall when the sewage tank is in the horizontal position. The upper half of the supporting plate 122 may have a gap with the inner wall of the recovery tank 1, so that the flow of water in the first space 111 to the second space 112 can be accelerated when the sewage tank is not in a lying state.

Referring to fig. 10 and 11, a mounting frame 15 is provided at an opening of the recovery tank 1, and the mounting frame 15 is used for mounting a filtering sea kerchief 151 and a conductive detector 152. The mounting frame 15 is further defined with a communication port 168, and the gas flow after gas-liquid separation sequentially passes through the first space 111, the communication port and the filter hepa 151 and then flows out of the recovery tank 1. The conductive detector 152 is used for sensing whether the liquid in the recovery tank 1 reaches a preset level. When the liquid level reaches the preset liquid level, the conductive detector 152 is turned on, and an alarm signal is sent. In order to further improve the gas-liquid separation efficiency, the first space 111 is further provided with a gas-liquid separator 16 for separating the dirt from the gas, and the gas-liquid separator 16 includes a U-shaped baffle 161 and an arc-shaped baffle 162 provided at one end of the U-shaped baffle 161. The arc-shaped baffle 162 includes a closing section 163 and an opening section 164, the closing section 163 is used for closing the upper end of the arc-shaped baffle 162, and the opening section 164 is disposed on the opening 169 side of the U-shaped baffle. The arc-shaped deflector 162 is provided with a plurality of flow guiding grooves 165, and the flow guiding grooves 165 are used for guiding fluid flowing out from the outlet of the liquid inlet pipe 17 after being scattered. If there is no flow guide groove 165, the fluid will impact on the flat surface of the flow guide plate, the fluid will splash, and then a large amount of water vapor is generated, and when the water vapor is not collected into water drops, the water vapor is taken away by the air flow to the communication port 168. After a large amount of water vapor is sucked to the motor, the service life of the motor is influenced, and a large amount of water vapor is filtered by the HEPA 151, so that peculiar smell is easy to generate. Similarly, no gap exists between two adjacent diversion trenches 165, so that when the recovery box 1 is in a lying state, air flow after gas-liquid separation directly flows to the communication opening 168 positioned on the mounting frame 15, and a large amount of water spray is prevented from being blown up. The liquid gathers along the diversion trench 165 and flows to a position far away from the communication opening 168, so as to avoid being blown away by the air flow.

Referring to fig. 8, the cleaning liquid tank 3 and the recovery tank 1 may be integrally formed. Thus, when the user removes the recovery tank 1, the cleaning liquid tank 3 can be removed together with the recovery tank 1, and the cleaning liquid tank 3 can be refilled by the way when the recovery tank 1 is cleaned. When the body 10 of the surface cleaning apparatus 101 is substantially flat with the surface to be cleaned, the cleaning liquid tank 3 is located directly above the recovery tank 1.

Although embodiments of the present invention have been disclosed above, it is not limited to the details and embodiments shown and described, it is well suited to various fields of use for which the invention would be readily apparent to those skilled in the art, and accordingly, the invention is not limited to the specific details and illustrations shown and described herein, without departing from the general concepts defined in the claims and their equivalents.
