[0026] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by technicians in the technical field of the present invention.

[0027] A floor scrubber is an efficient and convenient cleaning device, and its main function is to deeply clean the floor by brushing and sucking dirt. A floor scrubber generally includes a floor scrubber head and a dirt suction assembly. The floor scrubber head is generally provided with a roller brush assembly and a dirt suction port connected to the dirt suction assembly. During use, the dirt suction port sucks the dirt rolled back by the roller brush assembly into the dirt suction assembly. When the existing floor scrubber head is cleaning the floor, the dirt rolled back by the roller brush assembly is easily adsorbed on the surface of the dirt suction channel connected to the dirt suction port, resulting in the dirt rolled back by the roller brush assembly being unable to effectively enter the dirt suction assembly, affecting the cleaning effect and efficiency.

[0028] In the embodiment of the present application, a wavy sewage suction channel connected to the sewage suction port is provided on the head body of the floor scrubber, so that a strong turbulence effect can be generated when the fluid flows through the wavy sewage suction channel. The turbulence will form small vortices and small bubbles, which can roll away the dirt remaining on the surface of the wavy sewage suction channel. In this way, the possibility of dirt being adsorbed on the surface of the sewage suction channel can be reduced, so that the dirt rolled back by the roller brush assembly can effectively enter the sewage suction assembly.

[0029] In order to facilitate readers to understand the inventive concept of the present application, the specific structure of the floor scrubber head is described below:

[0030] See also Figure 1-3The floor scrubber head 1000 includes a head body 100 and a roller brush assembly 200. The head body 100 is provided with a wavy sewage suction channel 11 and a sewage suction port 100a. One end of the sewage suction channel 11 is connected to the sewage suction port 100a, and the sewage suction port 100a is used to connect to the sewage suction assembly; the roller brush assembly 200 is rotatably installed at the front end of the head body 100, and the other end of the sewage suction channel 11 faces the roller brush assembly 200. The sewage suction channel 11 and the sewage suction port 100a are used for allowing the dirt rolled back by the roller brush assembly 200 to pass through and enter the sewage suction assembly. In this way, when the floor scrubber head 1000 is working, negative pressure will be formed near the sewage suction port 100a, and the external gas will flow through the roller brush assembly 200, the sewage suction channel 11, the sewage suction port 100a and the sewage suction assembly in sequence, thereby driving the dirt rolled back by the roller brush assembly 200 to enter the sewage suction assembly through the sewage suction port 100a, wherein the dirt rolled back by the roller brush assembly 200 is easily combined with the gas during the process of being sucked into the sewage suction port 100a, thereby forming a fluid state, and when the fluid flows through the wavy sewage suction channel 11, a strong turbulence effect can be generated, and the turbulence will form small vortices and small bubbles, which can roll away the dirt remaining on the surface of the wavy sewage suction channel 11, thus reducing the possibility of dirt being adsorbed on the surface of the sewage suction channel 11.

[0031] For details, please refer to Figure 4 The head body 100 is provided with a wavy concave-convex portion 111 on the inner surface of the sewage suction channel 11, so that a strong turbulence effect can be generated when the fluid flows through the concave-convex portion 111. Obviously, the concave-convex portion 111 is arranged at different positions on the inner surface of the sewage suction channel 11 to produce different turbulence effects. In addition, different shapes and numbers of the concave-convex portions 111 can also produce different turbulence effects.

[0032] In a preferred embodiment, the concave-convex portion 111 is disposed at one end of the sewage suction channel 11 away from the sewage suction port 100a, so that the disturbance flow generated at the end of the sewage suction channel 11 away from the sewage suction port 100a can follow the fluid flow to the sewage suction port 100a, that is, the disturbance flow can cover the entire sewage suction channel 11 to a large extent, thereby sweeping away a large area of ​​the dirt remaining on the surface of the sewage suction channel 11. Further, the concave-convex portion 111 is in a strip shape, so that the strip-shaped concave-convex portion 111 can extend from one end of the sewage suction channel 11 to the other end, and only a few concave-convex portions 111 need to be designed to cover most of the area of ​​the sewage suction channel 11, thereby reducing the number of concave-convex portions 111 required, thereby reducing the processing procedures of the sewage suction channel 11. Further, considering that when the concave-convex portion 111 is parallel to the horizontal plane, the strip-shaped concave-convex portion 111 may be parallel to the flow direction of the fluid, and at this time, no turbulence effect is generated when the fluid flows through the concave-convex portion 111; when the concave-convex portion 111 is perpendicular to the horizontal plane, the strip-shaped concave-convex portion 111 may be perpendicular to the flow direction of the fluid, and at this time, a strong turbulence effect is generated when the fluid flows through the concave-convex portion 111, but at the same time, the resistance of the concave-convex portion 111 to the fluid is also very large, thereby reducing the efficiency of the floor scrubber head 1000 in adsorbing dirt; therefore, the angle between the concave-convex portion 111 and the horizontal plane is preferably an acute angle, such as In this way, the possibility that the strip-shaped concave-convex portion 111 is parallel to or perpendicular to the direction of fluid flow can be reduced, so that when the fluid flows through the concave-convex portion 111, a turbulent flow effect can be generated with less resistance, that is, the turbulent flow effect and resistance of the fluid can be better balanced; further, the number of the concave-convex portions 111 is multiple, and along the direction from the other end of the sewage suction channel 11 to one end of the sewage suction channel 11, the multiple concave-convex portions 111 are arranged in a stepped manner. In this way, when the fluid flows through the multiple concave-convex portions 111 arranged in a stepped manner, a self-spinning stepped turbulent flow effect can be generated, thereby improving the waste recovery efficiency.

[0033] It can be understood that the position of the concave-convex portion 111 in the sewage suction channel 11 is not limited. For example, the concave-convex portion 111 is set in the middle of the inner surface of the sewage suction channel 11 or at one end close to the sewage suction port 100a; the shape of the concave-convex portion 111 is also not limited. For example, the concave-convex portion 111 can be rectangular or circular.

[0034] In some embodiments, please refer to Figure 5 , along the direction from one end of the sewage suction channel 11 to the other end of the sewage suction channel 11, the sewage suction channel 11 protrudes from the sewage suction port 100a, so that it is beneficial for the sewage to flow into the sewage suction port 100a along the sewage suction channel 11, and the sewage can be Figure 5In some embodiments, the head body 100 is further provided with a curved connection portion 12, one end of which is connected to one end of the sewage suction channel 11, and the other end of which is connected to the sewage suction port 100a, so that the connection portion 12 forms a similar guide structure to facilitate the introduction of sewage from the sewage suction channel 11 into the sewage suction port 100a.

[0035] Furthermore, the number of the connecting parts 12 and the number of the sewage suction channels 11 are both two, and the two connecting parts 12 and the two sewage suction channels 11 are respectively arranged on both sides of the sewage suction port 100a, one end of one connecting part 12 is connected to one end of one sewage suction channel 11, and the other end of one connecting part 12 is connected to the sewage suction port 100a, and along the direction of the sewage suction channel 11 toward the sewage suction port 100a, the distance between the two connecting parts 12 gradually decreases to form a similar gathering structure, so that dirt can be introduced into the sewage suction port 100a from the sewage suction channels 11 on both sides of the sewage suction port 100a. In addition, by reducing the distance between the two connecting parts 12, the size of the sewage suction port 100a can also be narrowed. Under the same working power, the narrower sewage suction port 100a of the floor scrubber head 1000 can have a better wind force utilization rate. It is understandable that the number of the connecting parts 12 and the sewage suction channels 11 is not limited to two. For example, the number of the connecting parts 12 and the sewage suction channels 11 is multiple, and the multiple connecting parts 12 and the multiple sewage suction channels 11 are respectively arranged around the sewage suction port 100a.

[0036] In some embodiments, please refer to Figure 6 The floor scrubber head 1000 further includes a scraper blade 300, which is fixed to the head body 100 and is used to scrape dirt off the floor; the scraper blade 300 is spaced apart from the roller brush assembly 200, and the other end of the dirt suction channel 11 is connected to the gap between the roller brush assembly 200 and the scraper blade 300, so that the dirt between the roller brush assembly 200 and the scraper blade 300 can be sucked into the dirt suction channel 11, and the dirt can be Figure 6The direction indicated by the middle arrow flows into the sewage suction port 100a; further, the scraper blade 300 is arranged between the sewage suction channel 11 and the roller brush assembly 200, that is, the roller brush assembly 200 is closer to the front end of the floor scrubber head 1000 than the scraper blade 300, so that the floor scrubber head 1000 can roll first and then scrape, thereby having a better cleaning effect. It can be understood that the relative position between the scraper blade 300 and the roller brush assembly 200 is not limited, for example, the roller brush assembly 200 is arranged between the sewage suction channel 11 and the scraper blade 300, or the roller brush assembly 200 and the scraper blade 300 are respectively arranged at both ends of the floor scrubber head 1000, and there are two connecting structures between the sewage suction port 100a and the sewage suction channel 11, one connecting structure between the sewage suction port 100a and the sewage suction channel 11 is close to the roller brush assembly 200, and the other connecting structure between the sewage suction port 100a and the sewage suction channel 11 is close to the scraper blade 300.

[0037] In some embodiments, the floor scrubber head 1000 further includes a front cover 400, which is detachably mounted on the head body 100, and the front cover 400 is spaced apart from the roller brush assembly 200, and the other end of the sewage suction channel 11 is connected to the gap between the roller brush assembly 200 and the front cover 400, so that the dirt between the roller brush assembly 200 and the front cover 400 can be sucked into the sewage suction channel 11, and the dirt can be as Figure 6 The front cover 400 is used to cover the roller brush assembly 200 to block the dirt rolled back by the roller brush assembly 200 and reduce the possibility of dirt flying around due to the rolling of the roller brush assembly 200. In some embodiments, the floor scrubber head 1000 further includes an upper cover 500, which is detachably mounted on the top of the head body 100. The upper cover 500 is used to cover the head body 100 to reduce the possibility of dirt entering the head body 100 and make the floor scrubber head 1000 more beautiful.

[0038] In the embodiment of the utility model, the floor scrubber head 1000 includes a head body 100 and a roller brush assembly 200, the head body 100 is provided with a wavy sewage suction channel 11 and a sewage suction port 100a, one end of the sewage suction channel 11 is connected to the sewage suction port 100a, and the sewage suction port 100a is used to connect the sewage suction assembly; the roller brush assembly 200 is rotatably mounted on the front end of the head body 100, the other end of the sewage suction channel 11 faces the roller brush assembly 200, and the sewage suction channel 11 and the sewage suction port 100a are used for the dirt rolled back by the roller brush assembly 200 to pass through to enter the sewage suction Component; the dirt rolled back by the roller brush component 200 is easily combined with the gas during the process of being sucked into the sewage suction port 100a, thereby forming a fluid state. By setting a wavy sewage suction channel 11 connected to the sewage suction port 100a on the head body 100, a strong turbulence effect can be generated when the fluid flows through the wavy sewage suction channel 11. The turbulence will form small vortices and small bubbles, which can roll away the dirt remaining on the surface of the wavy sewage suction channel 11. In this way, the possibility of dirt being adsorbed on the surface of the sewage suction channel 11 can be reduced, so that the dirt rolled back by the roller brush component 200 can effectively enter the sewage suction component, thereby improving the cleaning effect and efficiency.
