In one embodiment, the blocking member 2 is located in any of the inlet branches of the three-way branch 5, the blocking member 2 has a through hole for the liquid to flow through and a blocking surface 21 for blocking, and the blocking surface 21 may be formed by a local area on the outer wall. The example of the blocking member 2 being located in the first inlet branch 51, coaxially to the first inlet branch 51, is described. When the blocking member 2 slides in the first inlet branch 51 to the first position, the through hole communicates the first inlet branch 51 and the outlet branch 53 to open the first return passage, and the blocking surface 21 blocks the inlet of the second inlet branch 52 at the three-way suction port, i.e. blocks the second return passage. When the blocking member 2 slides to the second position, the second return channel is conducted, and the blocking surface 21 blocks the first inlet branch 51.

Specifically, as shown in fig. 1 and 2, on the floor brush assembly, the three-way branch 5 is T-shaped or T-like, and the second inlet branch 52 and the outlet branch 53 are coaxial or substantially coaxial and are located at the axial end of the first inlet branch 51 (the first inlet branch 51 may be vertically disposed, and one end of the inlet is regarded as the top end). The blocking member 2 is located in one of the inlet branches and is tubular, and the first orifice of the through hole is in the axial direction and the second orifice is opened in the radial direction. The blocking surface 21 is an inclined surface which is obliquely opposite to both the first orifice and the second orifice, i.e. the blocking surface 21 has an angle with both the axial direction and the radial direction. Meanwhile, in the radial direction in the branch pipe cavity, the blocking surface 21 can block the pipe cavity of the branch pipe where the blocking piece 2 is located from one end of the pipe cavity in the radial direction to the other end of the pipe cavity in the radial direction.

Alternatively, the blocking member 2 may be a cylinder, the through hole extends along the axial direction, the first aperture is opened in the axial direction, the second aperture is opened in the radial direction, and the blocking surface 21 is formed by the outer end surface of the cylinder in the axial direction far away from the first aperture.

As shown in FIG. 1, when the blocking member 2 is moved to the end of the first inlet branch 51 and is located at the first position, the blocking surface 21 blocks the inlet of the second inlet branch 52 on the three-way suction port, the second opening of the through hole is opposite to and communicated with the outlet branch 53, and the first return passage is communicated. As shown in fig. 2, when the blocking member 2 moves to the top end of the first inlet branch 51 and moves to the position above the outlet branch 53, the blocking surface 21 blocks the lumen of the first inlet branch 51, and the sidewall of the first inlet branch 51 also blocks the second opening of the through hole, so that the first return channel is closed and the second return channel is open.

In this embodiment, when the blocking member 2 moves to the first position, the blocking member can be blocked and limited by the tube wall of the second return channel, that is, when the blocking member 2 moves to the end of the first inflow branch 51 and the tube wall of the second return channel is abutted, the blocking member is located at the first position where the first return channel is conducted. And a limiting member 3 for limiting when the blocking member 2 moves to the second position is provided at the top end of the first inlet branch 51. The limiting member 3 is located in the first inlet branch 51 or connected to the pipe orifice of the first inlet branch 51. The limiting part 3 is provided with a through hole.

When the first return channel is used, the first cover 6 of the floor brush assembly is connected to the base, and the suction port channel on the first cover 6 for liquid to flow into is opposite to and communicated with the pipe orifice, and flows back through the suction port channel on the first cover 6 and the first return channel on the main body 1. When needs wash, pull down first lid 6, through buckle structure, pull down locating part 3 conveniently, locate intraductal block 2 with sliding again and take off, accomplished the dismantlement promptly, can wash tee bend suction inlet and return flow path inner chamber. After the cleaning is finished, the blocking pieces 2 and the limiting pieces 3 are installed back to the main body 1 one by one, and the operation is very convenient.

The limiting member 3 comprises a sleeve 31 and an elastic buckle piece 32 arranged outside the sleeve 31, one end of the elastic buckle piece 32 is connected with the outer wall of the sleeve 31, the other end of the elastic buckle piece 32 is spaced from the outer wall of the sleeve 31, and a buckle body is arranged on the side wall of the elastic buckle piece 32. The elastic buckle piece 32 can generate elastic deformation in the radial direction of the sleeve 31 and can be detachably connected with the main body 1, and the main body 1 is provided with a buckle groove for embedding the buckle body. The elastic buckle piece 32 generates elastic deformation in the radial direction of the sleeve 31 and is connected with or detached from the main body 1, so that the disassembly and assembly operation is very convenient, and the use is convenient.

The inner diameter of the sleeve 31 may be smaller than the inner diameter of the orifice of the first inlet branch 51, and the blocking member 2 is blocked by the outer end surface of the sleeve 31. Or, an inverted groove 33 (with the notch facing the blocking piece) is further arranged on the outer wall of the sleeve 31, the rib plate 22 extending into the inverted groove 33 is arranged on the outer wall of the blocking piece 2, and a communication opening communicated with the sleeve 31 for the rib plate 22 to slide is formed in the side wall of the inverted groove 33. When the blocking element 2 is moved to the second position, in which the top of the rib 22 abuts against the bottom of the inverted groove 33, the second return channel is opened.

For simple structure, in one embodiment, the driving member is an elastic member 4, and the elastic member 4 can be elastically deformed to drive the blocking member 2 to displace by restoring the acting force generated during deformation.

As shown in fig. 4, 5 and 6, the elastic member 4 is a spring, the blocking member 2 has a cylinder for the spring to be sleeved on and a plate connected between the main body 1 and the outer wall of the blocking member 2, a spring cavity 54 for accommodating the spring is disposed beside the lumen of the first inlet branch 51, and an opening communicated with the lumen of the first inlet branch 51 for plate displacement is disposed on the side wall of the spring cavity 54. The top end of the spring chamber 54 is sealed to prevent liquid from escaping from the spring chamber 54. The cavity opening can be sealed by a cover plate, and can also be closed by covering an inverted groove 33 on the limiting part 3.

The driving member may also be a magnetic member, and the blocking member 2 has a region formed by a ferrous material, or the blocking member 2 has another magnetic member that is attracted or repelled by the magnetic member.

Of course, the driving member for driving the blocking member 2 to displace may be a motor or a cylinder.

When the driving member is a member that applies a unidirectional acting force, such as the elastic member 4 or the magnetic member, the blocking member 2 is driven to displace in a certain direction, for example, from the second position to the first position, and the force required for displacing the blocking member 2 from the first position to the second position can be applied by other acting members. For example, the first cover 6 has a pressing ring 62 provided at the outlet of the suction port passage 61, and when the first cover 6 is coupled to the main body 1, the pressing ring 62 protrudes into the first flow inlet branch 51 to press against the blocking member 2, so that the blocking member 2 moves from the first position to the second position, and at the same time, the elastic member 4 is deformed. When the second backflow channel is needed for backflow, the first cover body 6 can be detached, and the pressing effect of the pressing ring 62 on the blocking piece 2 is eliminated. The blocking member 2 is moved to the first position by the driving member. At this time, the limiting member 3 and the pipe orifice of the first inlet branch 51 can be covered by the second cover body to prevent impurities from falling.
