Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to an improved floor scrubbing vehicle. Background Technology

[0002] Current floor scrubbing vehicles, as described in Chinese Patent Application No. 202010476922.5 entitled "A Floor Scrubbing Vehicle," typically have the suction motor directly fixed to the cleaning water tank. The cleaning water tank must bear the weight of the suction motor, requiring high structural strength, which makes it relatively heavy and inconvenient to transport and assemble during production. Furthermore, to accommodate the suction motor, the cleaning water tank has a motor housing cavity. The top of the motor housing cavity has an exhaust vent communicating with the top of the suction motor, the bottom of the motor housing cavity has a first cooling vent, and the side wall of the motor housing cavity has a second cooling vent. This structure makes the cleaning water tank complex, increases the difficulty of designing the production mold, and raises mold-making costs. Utility Model Content

Detailed Implementation

[0023] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7As shown, an improved floor scrubbing vehicle of this embodiment includes a chassis 1; a cleaning assembly 12 and a squeegee assembly 13 are installed below the chassis 1; a clean water tank 2, a cleaning motor 3, a suction device 4, and a wastewater tank 5 are provided above the chassis 1; the clean water tank 2 is used to supply water to the cleaning assembly 12; the cleaning motor 3 is used to drive the cleaning assembly 12 to work; the suction device 4 is used to create negative pressure in the wastewater tank 5 to suck in wastewater from the squeegee assembly 13; and an installation cavity 2 is formed on the top surface of the clean water tank 2. 1; The bottom of the mounting cavity 21 is provided with a mounting opening 22, which connects the bottom of the clean water tank 2 and the mounting cavity 21; A mounting frame 6 is mounted on the chassis 1; The upper part of the mounting frame 6 extends into the mounting cavity 21 through the mounting opening 22; Each of the two opposite sides of the suction device 4 is provided with a support plate part 41; The suction device 4 is embedded in the mounting frame 6, and each support plate part 41 of the suction device 4 is supported by the mounting frame 6, and each support plate part 41 is fixed together with the mounting frame 6. The suction device 4 is fixed to the chassis 1 via the mounting bracket 6. The suction device 4 does not require a structure mounted on the clean water tank 2, thus reducing the structural strength requirements of the clean water tank 2 in this improved floor scrubber. The weight of the clean water tank 2 is lighter compared to existing technologies, facilitating handling and assembly during production. Furthermore, the mounting cavity 21 of this improved floor scrubber does not need to be connected to the suction device 4, eliminating the need for detailed structures such as exhaust vents and cooling vents. During use, the suction device 4 directly exhausts and cools through the gaps in the chassis 1, greatly simplifying the structure of the clean water tank 2 and reducing mold design and opening costs. In addition, during assembly, the suction device 4 simply needs to be embedded into the mounting bracket 6, ensuring that each support plate 41 of the suction device 4 is supported by the mounting bracket 6 before being fixed, making assembly very convenient.

[0024] To make the structure of this improved floor scrubber more reasonable, such as Figure 5 , Figure 7 As shown, the chassis 1 is bent upwards to form a baffle portion 11; the baffle portion 11 extends into the mounting port 22 of the clean water tank 2, and the rear wall of the mounting port 22 abuts against the baffle portion 11. The clean water tank 2 of this improved floor scrubber is fixed to the chassis 1 by screws locked into its bottom surface. During the cleaning process, the friction between this improved floor scrubber and the ground is relatively large. The structure of the baffle portion 11 on the chassis 1 of this improved floor scrubber ensures that when the worker pushes the clean water tank 2 to move the chassis 1, the clean water tank 2 pushes the baffle portion 11 of the chassis 1, causing the chassis 1 to move. This avoids deformation of the screw holes on the bottom surface of the clean water tank 2 where the screws are connected, making the connection structure of this improved floor scrubber more robust.

[0025] To make the structure of mounting bracket 6 more reasonable, such as Figure 5 , Figure 6As shown, the mounting frame 6 is integrally bent to form a base plate 61, a front upright plate 62, and a rear upright plate 63; the base plate 61 is fixedly connected to the chassis 1; the bottom edges of the front upright plate 62 and the rear upright plate 63 are each connected to the base plate 61, and the front upright plate 62 and the rear upright plate 63 are arranged opposite to each other; the suction device 4 is located between the front upright plate 62 and the rear upright plate 63, and the top edges of the front upright plate 62 and the rear upright plate 63 are each bent to form a folded plate portion 64 for supporting the support plate portion 41. The mounting frame 6 with this structure can be constructed by bending a single plate, which is very easy to produce and helps to improve production efficiency.

[0026] Furthermore, such as Figure 3 , Figure 5 , Figure 6 As shown, each of the front upright plate 62 and the rear upright plate 63 has an insertion slot 65 on one side; it also includes a partition 7; the partition 7 is integrally bent to form a horizontal plate 71 and a vertical plate 72; one side of the horizontal plate 71 is connected to the bottom edge of the vertical plate 72, and each end of the horizontal plate 71 has an insertion protrusion 73. The two insertion protrusions 73 of the horizontal plate 71 are inserted into the insertion slots 65 of the front upright plate 62 and the rear upright plate 63 one by one, so that the partition 7 is connected to the mounting bracket 6; it also includes an electrical control module 8; the electrical control module 8 is installed on the top surface of the horizontal plate 71, and the electrical control module 8 and the suction device 4 are distributed on the left and right sides. The vertical plate 72 is used to separate the electrical control module 8 from the suction device 4; the electrical control module 8 is electrically connected to the suction device 4 and the cleaning motor 3. This structure, in which the two insert protrusions 73 of the horizontal plate 71 are inserted one-to-one with the insert seams 65 of the front upright plate 62 and the rear upright plate 63, connects the partition 7 to the mounting bracket 6. No welding or screw connection is required between the partition 7 and the mounting bracket 6, greatly improving production efficiency. Furthermore, the electrical control module 8 and the suction device 4 are separated to prevent the heat or airflow generated by the suction device 4 from affecting the service life of the electrical control module 8 during use.

[0027] To make the structure of this improved floor scrubber more reasonable, such as Figure 3 , Figure 4 , Figure 7 As shown, this improved floor scrubber also includes a battery 9 and a mounting bracket 10; the battery 9 is placed on the bottom of the mounting cavity 21, and is located behind the mounting bracket 6. The battery 9 is electrically connected to the electronic control module 8; the mounting bracket 10 is integrally bent to form a side plate 101 and a front panel 102; the top edge of the side plate 101 is connected to one side edge of the front panel 102, the bottom edge of the side plate 101 is fixedly connected to the bottom of the mounting cavity 21, and the side of the front panel 102 away from the side plate 101 is fixedly connected to the clean water tank 2. The battery 9 is clamped and fixed within the space enclosed by the mounting bracket 10 and the mounting cavity 21.

[0028] like Figure 1 , Figure 2 , Figure 3, Figure 4 , Figure 5 , Figure 7 As shown, this improved floor scrubbing vehicle also includes a cover plate 20; the cover plate 20 is fixedly placed on the top surface of the mounting frame 6, and a through hole 201 is formed on the cover plate 20 for the suction end of the suction device 4 to extend out. After the mounting frame 6 is connected to the cover plate 20, the mounting frame 6 is not easily deformed; the top surface of the cover plate 20 is coplanar with the top surface of the panel 102 of the fixing frame 10; the left and right sides of the clean water tank 2 each have a recess 23, and each recess 23 connects the mounting cavity 21 and the side of the clean water tank 2; the wastewater tank 5 is installed in the mounting cavity 21, and the left and right sides of the wastewater tank 5 are respectively embedded in the recesses 23 on the left and right sides of the clean water tank 2, and the bottom surface of the wastewater tank 5 is supported by the top surface of the cover plate 20 and the top surface of the panel 102. This structure allows most of the weight of the wastewater tank 5 to be supported by the chassis 1, preventing the clean water tank 2 from deforming; in addition, the left and right sides of the wastewater tank 5 are exposed to facilitate the removal of the wastewater tank 5 for cleaning.

[0029] To make the structural layout of this improved floor scrubber more reasonable, such as Figure 3 , Figure 5 , Figure 7 As shown, a receiving cavity 24 is formed on the bottom surface of the clean water tank 2; the receiving cavity 24 is located in front of the mounting cavity 21, and the rear wall of the receiving cavity 24 is connected to the lower part of the front wall of the mounting cavity 21; the cleaning motor 3 is located inside the receiving cavity 24, and the cleaning motor 3 is located in front of the electronic control module 8. This structure allows the cleaning motor 3 and the suction device 4 to be staggered, resulting in a more even distribution of force on the chassis 1 and smoother movement during use; the structure of the receiving cavity 24 being connected to the mounting cavity 21 simplifies the structure of the clean water tank 2, thereby further reducing the production cost of the clean water tank 2.

[0030] To facilitate the operation of this improved floor scrubber, such as Figure 1 , Figure 7 As shown, the mounting cavity 21 is formed in the middle of the top surface of the clean water tank 2, and the mounting recess 25 is formed at the rear end of the top surface of the clean water tank 2. The mounting recess 25 connects the rear cavity wall of the mounting cavity 21 with the rear side of the clean water tank 2. A metal plate 26 is installed on the bottom surface of the mounting recess 25 to enhance the structural strength of the clean water tank 2. A handle 30 is also included. The bottom end of the handle 30 is connected to the metal plate 26 via a rotation positioning mechanism 40. A control module is provided on the handle 30, which is electrically connected to the electronic control module 8 to control the cleaning motor 3 and the suction device 4. During use, the handle 30 switches between a folded state and an unfolded state under the action of the rotation positioning mechanism 40. When not in use, the handle 30 can be folded, making this improved floor scrubber occupy less space when not in use.

[0031] To protect the suction device 4 and prevent dust from entering it during operation, such as Figure 1 , Figure 2 , Figure 4 As shown, this improved floor scrubber also includes a filter module 50; a front recess 52, a mounting groove 51, and a rear recess 53 are sequentially provided on the top surface of the wastewater tank 5 along the front-to-back direction; the filter module 50 is installed in the mounting groove 51, and a middle recess 501 is provided on the top surface of the filter module 50, which connects the front and rear sides of the filter module 50; the front recess 52 connects the front end of the wastewater tank 5 to the front wall of the mounting groove 51; the rear recess 53 connects the rear end of the wastewater tank 5 to the rear wall of the mounting groove 51; the front recess 52, the middle recess 501, and the rear recess 53 are connected to form a handle recess; the suction end of the suction device 4 is connected to the wastewater tank 5 through the filter module 50. This structure also allows the handle 30 to be embedded in the handle recess when folded, thus making this improved floor scrubber smaller in size when not in use.
