DETAILED DESCRIPTION

[0022] The following is a combination of the appended examples of the present invention Figure 1-6 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] As shown in the figure, a small hand-push floor scrubber includes a frame plate 1, a handle bar 2, a brush head assembly 3, a squeegee assembly 4, a clean water tank 5 and a sewage tank 6. The brush head assembly 3 includes a brush head component 31, a drive motor 32 and a liquid sprayer. The squeegee assembly 4 includes a squeegee component 41 and a suction motor 42. The lower ends of the clean water tank 5 and the sewage tank 6 are respectively formed with a plurality of first limiting protrusions 51 and a second limiting protrusion 61. The frame plate 1 is provided with a plurality of first limiting holes 11 matching the first limiting protrusions 51 and a plurality of second limiting holes 12 matching the second limiting protrusions 61. The clean water tank 5 is placed on the frame plate 1 and is connected to the spray nozzle 41 provided below the frame plate 1. The liquid dispenser is connected so that the first limiting protrusion 51 is inserted into the first limiting hole 11 (the specific structure of the connection between the clean water tank 5 and the liquid sprayer has been fully disclosed in the prior art and will not be repeated here). An air intake 62 and a water inlet 63 are provided at the lower end of the sewage tank 6. The air intake 62 and the water inlet 63 are respectively fixedly connected with an air intake pipe 64 and a water inlet pipe 65 located in the sewage tank 6. The upper port of the air intake pipe 64 is higher than the upper port of the water inlet pipe 65. The sewage tank 6 is placed on the frame so that the second limiting protrusion 61 is inserted into the second limiting hole 12. The air inlet is communicated with the suction motor 42 provided below the frame plate 1, and the water inlet 63 is communicated with the squeegee assembly 41.

[0024] Specifically, the brush head assembly 3 is arranged on the frame plate 1 and cooperates with the clean water tank 5: the drive motor 32 is arranged on the frame plate 1 and the output shaft of the drive motor 32 passes through the frame plate 1 and is fixedly connected to the brush head assembly 31, the frame plate 1 is provided with an electrical box 7 located on one side of the drive motor 32, and the clean water tank 5 is formed with a accommodating cavity 52 for accommodating the drive motor 32 and a makeshift opening 53 that can expose the upper end of the electrical box 7, the drive motor 32 is placed in the accommodating cavity 52, the handle rod 2 is movably connected to the upper end of the electrical box 7 through the makeshift opening 53, and the electronic control device of the drive motor 32, the sprayer and the suction motor 42 is arranged in the electrical box 7.

[0025] Specifically, the handle rod 2 is movably connected to the structure of the electrical box 7: the upper end of the electrical box 7 is rotatably connected to the adapter block 71 that can swing back and forth, and the lower end of the handle rod 2 is connected to the adapter block 71 so as to swing left and right. The swing of the adapter block 71 on the electrical box 7 and the swing of the handle rod 2 on the adapter block 71 can realize multi-dimensional swing of the handle rod 2, which is convenient for controlling the moving direction of the floor scrubber.

[0026] After the cleaning machine is installed on the frame plate 1, the cleaning tank 5 and the sewage tank 6 are connected to each other, and the outer contours of the cleaning tank 5 and the sewage tank 6 match the outer contours of the frame plate 1. After the cleaning tank 5 and the sewage tank 6 are connected, they form a shell covering the components such as the drive motor 32 arranged on the frame plate 1. The overall height of the base part of the floor scrubber is only limited by the height of the drive motor 32, thereby making the overall height of the floor scrubber more compact and adaptable to more usage scenarios. After the cleaning tank 5 is placed on the frame plate 1, the first limiting protrusion 51 is automatically maintained in the first limiting hole 11 by the cleaning tank 5 and the clean water therein. The first limiting protrusion 51 cooperates with the first limiting hole 11 to limit the horizontal displacement of the cleaning tank 5 relative to the frame plate 1, so that the cleaning tank 5 remains on the frame plate 1 when the floor scrubber moves to supply clean water to the brush head assembly 31. Similarly, after the sewage tank 6 is placed on the frame plate 1, the second limiting protrusion 61 cooperates with the second limiting hole 12 to The sewage tank 6 remains on the frame plate 1 to store sewage when the floor scrubber is moved. When the clean water tank 5 or the sewage tank 6 needs to be removed from the frame plate 1, it is only necessary to lift the clean water tank 5 or the sewage tank 6 so that the first limiting protrusion 51 or the second limiting protrusion 61 can be withdrawn from the first limiting hole 11 or the second limiting hole 12. The operation is also very convenient. During the operation of the floor scrubber, sewage gathers in the squeegee assembly 41, and the suction motor 42 works to discharge the air in the sewage tank 6 through the suction port 62 and the suction pipe 64, so that the sewage tank 6 is in a negative pressure state. The sewage in the squeegee assembly 41 enters the sewage tank 6 through the water inlet 63 and the water inlet pipe 65 under the action of the pressure difference to realize sewage recovery. In the above-mentioned sewage recovery process, since the distance between the water inlet 63 and the squeegee is small, it is ensured that the sewage in the squeegee assembly 41 can be quickly sucked into the sewage tank 6, and it is not easy to remain in the water inlet pipe 65 and the squeegee assembly 41, thereby effectively preventing secondary pollution to the ground.

[0027] In addition, based on the above structure, the handle rod 2 is composed of a first rod body 21 and a second rod body 22 that are plugged together. The lower end of the first rod body 21 is connected to the adapter block 71, and the relative sliding of the first rod body 21 and the second rod body 22 is limited by the fastener 23. The fastener 23 can be a fastening bolt screwed on the second rod body 22 and tightly pressed against the first rod body 21, or it can be a clamp fixed on the second rod body 22 and tightly holding the first rod body 21. By loosening the fastener 23 and sliding the first rod body 21 and the second rod body 22 relative to each other, the overall length of the handle rod 2 can be adjusted to adapt to users of different heights. When storing the floor scrubber, the first rod body 21 is fully inserted into the rod body to adjust the length of the handle rod 2 to the shortest, and then the handle rod 2 is swung along the adapter block 71 and placed on the clean water tank 5, thereby reducing the space occupied by the floor scrubber and facilitating the storage and transportation of the floor scrubber.

[0028] In addition, on the basis of the above structure, a support plate 8 is fixedly provided on the frame plate 1 and is located below the air intake 62 and the water inlet 63. A first positioning ring 81 and a second positioning ring 82 are formed on the support plate 8. A positioning groove 66 matching with the support plate 8 is formed at the lower end of the sewage tank 6. The air intake 62 and the water inlet 63 are arranged on the bottom wall of the positioning groove 66. A first positioning step 661 and a second positioning step 662 are formed on the bottom wall of the positioning groove 66 to match the first positioning ring 81 and the second positioning ring 82 and are respectively located at the ports of the air intake 62 and the water inlet 63. The support plate 8 penetrates into the positioning groove 66 and rests on the bottom wall of the positioning groove 66, so that the first positioning ring 81 and the second positioning ring 82 are respectively inserted into the first positioning step 661 and the second positioning step 662 and are respectively interference fit with the side walls of the first positioning step 661 and the second positioning step 662. The input port of the suction motor 42 penetrates the first positioning ring 81 and the second positioning ring 82 The air intake 62 is connected, and the output port of the squeegee assembly 41 passes through the second positioning ring 82 and is connected to the water inlet 63. The support plate 8 passes through the positioning groove 66 and cooperates with the positioning groove 66 to limit the horizontal movement of the sewage tank 6 relative to the frame plate 1, thereby enhancing the stability of the sewage tank 6 on the frame, and the first positioning ring 81 and the second positioning ring 82 are respectively interfered with by the first positioning step 661 and the second positioning step 662 to limit the longitudinal displacement of the sewage tank 6 and the support plate 8, thereby ensuring that the sewage tank 6 can be stably placed on the frame plate 1 in an unloaded state, and the first positioning ring 81 and the second positioning ring 82 are respectively cooperated with the first positioning step 661 and the second positioning step 662 to provide a positioning effect for the position of the air intake 62 and the water inlet 63 relative to the support position, so that the air intake 62 and the water inlet 63 can be accurately aligned and connected with the input port of the suction motor 42 and the output port of the squeegee assembly 41.

[0029] In addition, on the basis of the above structure, a sewage outlet is provided at the lower end of the sewage tank 6, a cover 67 is screwed on the sewage outlet, and a through-hole 13 is provided on the frame plate 1 for the cover 67 to pass through. The cover 67 passes through the through-hole 13, and after the sewage tank 6 is removed from the frame plate 1, the cover 67 can be removed to allow the sewage in the sewage tank 6 to flow out autonomously, which is convenient for dumping the sewage. In addition, in order to facilitate cleaning of the sewage tank 6, a cleaning port is provided at the upper end of the sewage tank 6, and a cover is provided on the cleaning port.

[0030] In addition, based on the above structure, two first hand-picking grooves 54 are symmetrically formed on the side of the clean water tank 5, and two second hand-picking grooves 68 are symmetrically formed on the side of the sewage tank 6. The first hand-picking grooves 54 and the second hand-picking grooves 68 can be used to more conveniently lift the clean water tank 5 and the sewage tank 6, thereby facilitating the disassembly and assembly of the clean water tank 5 and the sewage tank 6.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
