Description

Technical Field

[0001] This utility model relates to the technical field of cleaning equipment, and in particular to a floor scrubber with a reinforced structure. Background Technology

[0002] Existing floor scrubbers, such as the Chinese utility model patent with publication number CN218220105U entitled "A Hand-Push Floor Scrubber," include a scrubber body with a wastewater tank at its upper end. A wastewater tank cover is hinged to the surface of the tank. A squeegee is located at the rear of the scrubber body, and a suction tube is attached to the lower surface of the squeegee, connected to the wastewater tank via a suction pump. In use, the wastewater tank cover is closed, creating a sealed space. The suction pump creates a negative pressure environment within the tank, drawing in and collecting the wastewater from the squeegee. As the water level in the tank rises, the liquid pressure on the lower part of the tank's inner wall increases, causing uneven stress between the upper and lower parts of the inner wall. This leads to deformation of the tank's inner wall, preventing a tight seal between the tank opening and the cover, reducing the scrubbing performance, decreasing the scrubber's suction capacity, and resulting in incomplete wastewater removal, making it inconvenient to use.

Detailed Implementation

[0026] like Figures 1 to 7 An embodiment of a floor scrubber with a reinforced structure includes a housing 1 and a chassis 8. The housing 1 is detachably mounted on the chassis 8. A mounting cavity 14 is formed on the bottom surface of the housing 1, and the mounting cavity 14 and the chassis 8 enclose a mounting space. A wastewater tank 11 is formed on the top surface of the housing 1. A first reinforcing rib 111 and a second reinforcing rib 112 are formed on the wastewater tank 11. The first reinforcing rib 111 and the second reinforcing rib 112 are arranged opposite each other on the inner walls of opposite sides of the wastewater tank 11 in the length direction. The first reinforcing rib 111 and the second reinforcing rib 112 are located near the middle position of the wastewater tank 11 in the length direction. The length direction of the first reinforcing rib 111 and the second reinforcing rib 112 is arranged vertically. The top ends of the first reinforcing rib 111 and the second reinforcing rib 112 are located near the opening of the wastewater tank 11. The system also includes a support member 2, and the two ends of the support member 2 are respectively connected to the top ends of the first reinforcing rib 111 and the second reinforcing rib 112.

[0027] The working principle of this embodiment is as follows:

[0028] By forming a first reinforcing rib 111 and a second reinforcing rib 112 vertically on the sewage tank 11, the inner wall of the sewage tank 11 has stronger resistance to bending. As the water level in the sewage tank 11 rises, the opening of the sewage tank 11 tends to deform inward. By setting a support member 2 between the first reinforcing rib 111 and the second reinforcing rib 112, the structural stability of the opening of the sewage tank 11 is ensured. Through the above design, the shell 1 of this floor scrubber has high structural strength, the sewage tank 11 is not easy to deform, and the sewage tank 11 can maintain good sealing performance with the sealing cover 3 of the floor scrubber during operation, so that the floor scrubber maintains good water absorption performance and is more convenient to use.

[0029] like Figure 2 and Figure 5 As shown, the two ends of the support member 2 are respectively formed with a locking groove 241. The length direction of the locking groove 241 is arranged vertically and connects the top surface and bottom surface of the support member 2. The top end of the locking groove 241 is formed with a positioning protrusion 242. The locking groove 241 at one end of the support member 2 is slidably disposed on the first reinforcing rib 111, and the locking groove 241 at the other end of the support member 2 is slidably disposed on the second reinforcing rib 112. The positioning protrusion 242 of each locking groove 241 is respectively supported on the top end of the corresponding first reinforcing rib 111 or second reinforcing rib 112. During installation, the support member 2 is inserted into the sewage tank 11 from above the opening of the sewage tank 11, so that the locking grooves 241 at both ends of the support member 2 can be slidably fitted onto the first reinforcing rib 111 and the second reinforcing rib 112 respectively. The support member 2 continues to slide downward until the positioning protrusions 242 of each locking groove 241 are supported on the top of the corresponding first reinforcing rib 111 or second reinforcing rib 112. Through this design, the installation and disassembly of the support member 2 are more convenient and quick, and maintenance is more convenient.

[0030] like Figure 2 and Figure 5 As shown, the support member 2 includes an upper crossbeam 21, a lower crossbeam 22, and a support plate 23. The upper crossbeam 21 and the lower crossbeam 22 are connected by the support plate 23. One end of the upper crossbeam 21, one end of the lower crossbeam 22, and one end of the support plate 23 are connected by a connecting column 24. The other end of the upper crossbeam 21, the other end of the lower crossbeam 22, and the other end of the support plate 23 are also connected by a connecting column 24. The connecting column 24 has the aforementioned locking groove 241 and positioning protrusion 242. The upper crossbeam 21 has an arc-shaped structure that is lower in the middle and higher at both ends. This structure enables the support member 2 to have high structural strength and bending resistance, further improving the structural strength of the sewage tank 11.

[0031] like Figure 4As shown, five first reinforcing grooves 12 are formed on the shell 1. The five first reinforcing grooves 12 are arranged in an X-shape directly below the sewage tank 11. The first reinforcing grooves 12 are cylindrical structures. By adopting a cylindrical structure, the first reinforcing grooves 12 have relatively balanced bending stiffness in all directions in the horizontal direction, which makes the bottom wall of the sewage tank 11 have good bending resistance, resulting in higher structural strength of the sewage tank 11 and making it less prone to deformation due to rising water levels.

[0032] like Figure 4 As shown, the groove opening and the wall, as well as the bottom of the groove and the wall, of the first reinforcing groove 12 are connected by arc surfaces. This structure eliminates the sharp corners of the first reinforcing groove 12, avoids local stress concentration in the first reinforcing groove 12, and results in a more reasonable stress structure and higher bending stiffness.

[0033] like Figure 4 As shown, the bottom surface of the shell 1 has two second reinforcing grooves 13. These two second reinforcing grooves 13 are arranged along the length of the sewage tank 11 directly below it. The five first reinforcing grooves 12 are located between the two second reinforcing grooves 13. The second reinforcing grooves 13 are elongated structures, with their length direction horizontal and perpendicular to the length direction of the sewage tank 11. By adopting an elongated structure and being perpendicular to the length direction of the sewage tank 11, the second reinforcing grooves 13 effectively strengthen the structural strength of the bottom wall of the sewage tank 11, making the sewage tank 11 less prone to deformation.

[0034] like Figure 4 As shown, the groove opening and the wall, as well as the bottom of the groove and the wall, of the second reinforcing groove 13 are connected by arc surfaces. This structure eliminates the sharp corners of the second reinforcing groove 13, avoids local stress concentration, and results in a more reasonable stress structure and higher bending stiffness.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, this embodiment also includes a sealing cover 3, a water scraper 4, and a negative pressure pump; the sealing cover 3 is movably connected to the housing 1, and the sealing cover 3 can close the slot of the sewage tank 11 to form a sealed sewage chamber; the water scraper 4 is set on the chassis 8, and the lower surface of the water scraper 4 is provided with a water suction space, which is connected to the sewage chamber through a sewage pipe 9; the negative pressure pump is hung on the housing 1 by a mounting bracket and is located in the placement space, and the negative pressure pump is connected to the sewage chamber through a negative pressure pipe, and the negative pressure pump is used to provide a negative pressure environment for the sewage chamber. The inner wall of the sewage tank 11 has an inlet hole 113 and a negative pressure hole 114 that communicate with the outside. It also includes a filter basket 5, a mounting connector 6, and a negative pressure connector 7. Both the mounting connector 6 and the negative pressure connector 7 are elbow structures. One end of the mounting connector 6 is the inlet end, and the other end is the outlet end. The inlet end of the mounting connector 6 is installed on the opening of the inlet hole 113 and communicates with the sewage pipe 9. The outlet end of the mounting connector 6 is positioned upwards and inside the sewage tank 11. The filter basket 5 has a mounting recess 52 and several filter holes 51. The filter holes 51 are not connected to the mounting recess 52. The mounting recess 52 connects the bottom surface of the filter basket 5 to an outer side surface. A fitting hole 521 communicating with the outer surface is formed on the top surface of the mounting recess 52. The filter basket 5 is hung on the mounting connector 6 through the mounting recess 52. The fitting hole 521 is fitted onto the outlet end of the mounting connector 6; one end of the negative pressure connector 7 is the mounting end, and the other end is the negative pressure end. The mounting end of the negative pressure connector 7 is installed on the opening of the negative pressure hole 114 and connected to the negative pressure pipeline. The negative pressure end of the negative pressure connector 7 is set upwards and is located inside the sewage tank 11; the sealing cover 3 has a flow guiding groove 31 and a waterproof groove 32. Both the flow guiding groove 31 and the waterproof groove 32 are cylindrical structures. The bottom and the wall of the flow guiding groove 31 are connected by an arc surface, and the bottom and the wall of the waterproof groove 32 are also connected by an arc surface. When the sealing cover 3 is in the closed sewage tank 11 state: the outlet end of the mounting connector 6 extends into the flow guiding groove 31, and the negative pressure end of the negative pressure connector 7 extends into the waterproof groove 32. Through the combination design of the mounting connector 6 and the filter basket 5, the installation and disassembly of the filter basket 5 are more convenient, and the cleaning of the filter basket 5 is more convenient. The design of the outlet end of the mounting connector 6 extending into the guide groove 31 allows the wastewater flowing out of the mounting connector 6 to be more evenly distributed by the guide groove 31, improving the filtration efficiency of the filter basket 5 and reducing the impact force of water flow on the filter basket 5. The design of the negative pressure end of the negative pressure connector 7 extending into the waterproof groove 32 prevents water splashes from entering the negative pressure connector 7 and then entering the negative pressure pump through the negative pressure pipeline, thus improving safety.

[0036] like Figure 6As shown, a liquid-retaining wall 33 is formed on the sealing cover 3. The liquid-retaining wall 33 partially surrounds the opening of the guide groove 31. When the sealing cover 3 is in the closed sewage tank 11 state, the liquid-retaining wall 33 and the wall of the sewage tank 11 form a closed structure. By adding the liquid-retaining wall 33, it can be ensured that the sewage flowing out of the guide groove 31 falls into the filter basket 5, ensuring that this floor scrubber has a good filtration effect on sewage.
