As shown in fig. 1 to 4, a cleaning head 100 according to an embodiment of the present invention includes a housing 1 and a roll brush assembly 2, the roll brush assembly 2 including a first roll brush 21 and a second roll brush 22, a first roll brush chamber 17 provided at a front portion of the housing 1, and a second roll brush chamber 16 provided at a rear portion of the housing 1. The first rolling brush 21 is provided in the first rolling brush chamber 17, and the second rolling brush 22 is provided in the second rolling brush chamber 16. A main suction passage 11, a first flow passage 12 and a second flow passage 13 are provided in the housing 1, and a lower end of the main suction passage 11 constitutes a main suction port 111.

Specifically, the first rolling brush 21 is provided at the front of the casing 1, the second rolling brush 22 is provided at the rear of the casing 1, and the main suction opening 111 is provided on the bottom surface of the casing 1. The first flow path 12 is located in front of the second flow path 13, and a first port (e.g., the front port, left port, of the first flow path 12 in fig. 2) of the first flow path 12 communicates with the first brush chamber 17, and a second port (e.g., the rear port, right port, of the first flow path 12 in fig. 2) of the first flow path 12 communicates with the main suction opening 111.

A first port (e.g., a rear port, a right port, of the second flow passage 13 in fig. 2) of the second flow passage 13 communicates with the second brush chamber 18, and a second port (e.g., a front port, a left port, of the second flow passage 13 in fig. 2) of the second flow passage 13 communicates with the main suction opening 111. The first upper wall surface 121 of the first flow passage 12 is orthogonal to the wall surface of the main suction opening 111, and the second upper wall surface 131 of the second flow passage 13 is orthogonal to the wall surface of the main suction opening.

According to the cleaning head 100 of the embodiment of the utility model, the first upper wall surface 121 of the first flow channel 12 and the second upper wall surface 131 of the second flow channel 13 are orthogonal to the wall surface of the main suction opening 111, so that the sewage sucked into the first flow channel 12 and the sewage sucked into the second flow channel 13 by the cleaning head 100 collide with each other when entering the main suction opening 111, the problem that the sewage in the first flow channel 12 and the sewage in the second flow channel 13 are mutually crossed is reduced, the energy loss is reduced, the cleaning capability of the cleaning head 100 is improved, and the cleaning efficiency is high.

Alternatively, the upper end of the first flow passage 12 has a first upper wall surface 121, the upper end of the second flow passage 13 has a second upper wall surface 131, the first upper wall surface 121 and the second upper wall surface 131 are located on the same horizontal plane, and the wall surface of the main suction opening 111 extends in the vertical direction. According to the cleaning head 100 of the embodiment of the utility model, the first upper wall surface 121 of the first flow channel 12 and the second upper wall surface 131 of the second flow channel 13 are arranged on the same horizontal plane, so that the sewage sucked into the first flow channel 12 and the sewage sucked into the second flow channel 13 by the cleaning head 100 collide with each other when entering the main suction opening 111, the energy loss is further reduced, the cleaning capability of the cleaning head 100 is improved, and the cleaning efficiency is high.

It will be appreciated that the main suction opening 111 has an axial direction which is orthogonal to the first and second upper walls 121, 131, in other words the main suction opening 111 has an axial direction which is orthogonal to the working plane of the cleaner head 100, and the first and second upper walls 121, 131 are arranged parallel to the working plane of the cleaner head 100, so that the suction force of the main suction opening 111 is equally distributed between the first and second flow paths 12, 13, and the dirt-absorbing capacity of the main suction opening 111 is increased, resulting in a better cleaning effect of the cleaner head 100.

Further, as shown in fig. 2, the lower end of the first flow passage 12 has a first lower wall surface 122, the lower end of the second flow passage 13 has a second lower wall surface 132, the first lower wall surface 122 is parallel to the first upper wall surface 121, and the second lower wall surface 132 is parallel to the second upper wall surface 131, it can be understood that the first upper wall surface 121 and the first lower wall surface 122 are arranged at intervals in the height direction (the up-down direction in fig. 2) of the housing 1. The second upper wall surface 131 and the second lower wall surface 132 are arranged at intervals in the height direction of the housing 1 (the up-down direction in fig. 2). Alternatively, the first lower wall 122 and the second lower wall 132 are located at the same level, and the cleaning head 100 according to the embodiment of the present invention can further reduce the problem that the polluted water is mixed in the first flow channel 12 and the second flow channel 13 by setting the first lower wall 122 and the second lower wall 132 at the same level, thereby reducing energy consumption and improving the cleaning capability of the cleaning head 100.

In some embodiments, as shown in fig. 2, the bottom of the housing 1 is provided with a water storage tank 14, the water storage tank 14 is arranged between the first flow passage 12 and the second flow passage 13, and the projection of the main suction opening 111 towards the water storage tank 14 is positioned in the water storage tank 14. It will be appreciated that the reservoir 14 is located directly below the main suction opening 111 so that when the cleaner head is deactivated, the dirty water attached to the main suction opening 111 can fall back into the reservoir 14 to prevent the dirty water from flowing to the outside along the first flow path 12 and the second flow path 13, improving the reliability of the cleaner head 100 during use and providing a better user experience.

In some embodiments, as shown in fig. 2, the distance between the first port of the first flow passage 12 and the second port of the first flow passage 12 is L1, and the distance between the first port of the second flow passage 13 and the second port of the second flow passage 13 is L2, wherein L1 is L2. It can be understood that the size of the first flow channel 12 in the front-back direction of the housing 1 is equal to the size of the second flow channel 13 in the front-back direction of the housing 1, so that the cleaning performance of the cleaning head 100 moving back and forth is stable, and the use experience of a user is improved.

Further, as shown in fig. 3 and 4, the cleaning head 100 further includes a water spray channel 3, the water spray channel 3 having a water inlet and a water spray 31 for spraying water toward at least one of the first rolling brush 21, the second rolling brush 22 and the surface to be cleaned. The roll brush assembly 2 further includes a first wiper blade 23, and the first wiper blade 23 is connected to the first upper wall surface 121 and abuts against the first roll brush 21. The roll brush assembly 2 further includes a second wiper blade 24, and the second wiper blade 24 is connected to the second upper wall surface 131 and abuts against the second roll brush 22. The cleaning head 100 according to the embodiment of the present invention may spray water to the first and/or second round brushes 21 and 22 through the water spray passage 3, and scrape contaminated water from the first and second round brushes 21 and 22 through the first and second wiper blades 23 and 24, so that the first and second round brushes 21 and 22 may be cleaned, thereby improving a cleaning effect of the cleaning head 100.

Specifically, as shown in fig. 2, the water jet 31 is provided above the first wiper blade 23, opposite to the first round brush 21. Further, the water spray 31 is opposed to the first roll brush 21 in a horizontal direction to spray water toward the first roll brush 21. It can be understood that, taking the first rolling brush 21 as an example, when the first rolling brush 21 rotates counterclockwise, the water spraying port 31 is located downstream of the first wiper blade 23, the first wiper blade 23 can avoid the main suction port 111 from directly sucking the clean water sprayed from the water spraying port 31, and the clean water can be brought to the floor for scrubbing along the rotation direction of the first rolling brush 21 due to the clockwise rotation of the first rolling brush 21, thereby improving the cleaning effect of the cleaning head 100.

Alternatively, as shown in fig. 4, the water spray opening 31 may be plural, and the plural water spray openings 31 are arranged at intervals along the axial direction of the first rolling brush chamber 15, so that the first rolling brush 21 can be sufficiently and comprehensively sprayed with water, thereby improving the cleaning effect of the cleaning head 100.
