Claims

1. A clean water tank for a surface cleaning apparatus adapted to dock with a base station for charging and / or replenishing a water supply, characterized in that, include: The housing is mounted on the floor brush of the surface cleaning equipment; A water inlet is located at the bottom of the housing and is used to connect with the water supply interface of the base station. A first water valve is provided at the water inlet interface. The first water valve has an open state and a closed state to open or close the water inlet interface. The ventilation structure includes a ventilation port and an opening and closing element for closing and opening the ventilation port. The ventilation port is located on the upper part of the tank and connects the inside of the clean water tank with the outside. When the floor brush of the surface cleaning device is placed in place on the base station, the first water valve switches to the open state, and the first water valve applies force to the ventilation structure to make the ventilation structure open.

2. The clear water tank according to claim 1, wherein The first water valve includes a first valve stem and a first reset member for resetting the first valve stem. Under the action of external force, the first valve stem can overcome the elastic force of the first reset member and switch to the open position. When the external force is removed, the first valve stem automatically returns to the closed position under the action of the first reset member.

3. The clean water tank as described in claim 2, characterized in that, The ventilation structure includes a ventilation reset member that acts on the opening and closing member to automatically close the ventilation port; the first valve stem, in the open position, overcomes the elastic force of the ventilation reset member and presses against the opening and closing member, and the ventilation port is in the open state; when the first valve stem returns to the closed position, the ventilation reset member pushes against the opening and closing member to close the ventilation port.

4. The clear water tank according to claim 3, wherein The opening and closing component includes a closing end for closing and opening the ventilation port, a trigger end for interacting with the first valve stem, and a pivot connection portion pivotally connected to the housing. The closed end and the trigger end are respectively disposed on both sides of the pivot connection. During the process of the first valve stem switching from the closed position to the open position, it presses against the trigger end, thereby causing the closed end to rotate around the pivot connection to open the air exchange port.

5. The clear water tank according to claim 4, wherein The ventilation reset component is a spring. A positioning post is provided on the side opposite to the first valve stem of the trigger end. One end of the ventilation reset component is sleeved on the positioning post, and the other end abuts against the inner wall of the box.

6. The clear water tank according to claim 4, wherein The opening and closing element is disposed through the air exchange port, the closed end is located outside the housing, and the opening and closing element also includes a trigger end located inside the housing, the trigger end being disposed opposite to the end of the first valve stem; During the switching process from the closed position to the open position, the first valve stem presses against the trigger end, which in turn moves the closed end away from the air exchange port, and an air exchange gap is formed between the opening / closing element and the air exchange port.

7. The clear water tank according to claim 6, wherein The opening and closing component includes a rod portion that penetrates the ventilation port. The rod portion includes a first end and a second end opposite to each other. The first end is located outside the clean water tank, and the second end is located inside the clean water tank. The closing end is located at the first end of the rod portion, and the trigger end is located at the second end of the rod portion. The ventilation reset component is sleeved on the rod portion, with one end abutting against the trigger end and the other end abutting against the inner wall of the clean water tank.

8. The clear water tank according to claim 1, wherein The housing includes a first volume section, a second volume section, and an intermediate volume section disposed between the first volume section and the second volume section, wherein the intermediate volume section is lower than the first volume section and the second volume section; The clean water tank also includes a connecting pipe, one end of which is connected to the upper space of the first volume section, and the other end of which is connected to the upper space of the second volume section.

9. The clear water tank according to claim 1, wherein The clean water tank also includes a duckbill valve, which is located on the top of the inner wall of the clean water tank.

10. A surface cleaning apparatus characterized by, It includes a floor brush and a clean water tank as described in any one of claims 1-9, wherein the clean water tank is disposed on the floor brush.

11. A surface cleaning system characterized by, Includes a base station and the surface cleaning device as described in claim 10.
