Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a detachable electrically driven device and a cleaning machine. Background Technology

[0002] In the existing technology, the cleaning roller of the floor scrubber has an inner drum inside the outer drum. The motor in the inner drum is powered by a power line introduced from one end of the inner drum that is hinged to the cleaning head. Since this end is hinged to the cleaning head, the end cannot be removed from the cleaning head along with the cleaning roller. At the same time, since the power line runs through the end, there are problems such as needing to cut the power line to completely remove the cleaning head and repair the drive motor, and needing to reconnect the cut power line when reinstalling after repair, making the disassembly and reassembly process cumbersome.

[0003] In the prior art, the motor fitted inside the cleaning roller only drives the cleaning roller itself and cannot drive other components.

[0004] In the existing technology, the wiping layer on the outer surface of the cleaning roller will wear down after a period of use. When the wear seriously affects the cleaning efficiency, the entire cleaning roller needs to be replaced. Because the current manufacturing process of cleaning rollers is relatively complex, it is not possible to quickly maintain and replace only the wiping layer of the cleaning roller. Instead, the entire cleaning roller needs to be replaced. Summary of the Invention

The second end of the hinged piece 2 is detachably electrically connected to the electrically connected end la of the electric drive assembly 1. The cleaning roller 202 is driven to rotate by the rotating output end lb of the end knob assembly 3. Since the cleaning machine 200 adopts all the technical solutions of the detachable electric drive device 100 described above, it also has the corresponding technical effects. Therefore, no further description is given here.

[0107] Specifically, in the embodiment of the present application, as shown in Figures 6 to 9 , the motor fixing part 2011 comprises a fixing part body 20111, a hinged joint accommodating cavity 20112 and a wire harness accommodating cavity 20113 which are arranged on the fixing part body 20111. The side wall of the hinged joint accommodating cavity 20112 is provided with a pin hole 20114 which is used to cooperate with the hinged pin 20115 to hinge the hinged piece 2. The wire harness accommodating cavity 20113 is used for the wire harness led out by the hinged piece 2 to pass through.

[0108] Specifically, in the embodiment of the present application, please further refer to Figures 1 to 5 、 Figure 8 、 Figure 11 、 Figures 14 to 17 , the fixing part body 20111 is provided with an annular clearance platform 20116 at the corresponding position of the pin hole 20114. The arrangement of the annular clearance platform 20116 provides a larger space for the fixing part body 20111 and the hinged piece 2 to move at the hinged position, which avoids the inconvenience of rotation of the fixing part body 20111 and the hinged piece 2 when the detachable electric drive device 100 is disassembled, and improves the convenience of disassembly.

[0109] Specifically, in the embodiment of the present application, as shown in Figure 9 、 Figure 11 、 Figure 15 、 Figure 16 and Figure 18As shown, the inner cylinder of the cleaning roller 202 is rotatably connected to the outer periphery of the motor fixing part 2011 at one end of the hinge 2 through a third bearing M, the outer periphery wall of the motor fixing part 2011 is transitionally fitted with the inner ring of the third bearing M, and the inner cylinder of the cleaning roller 202 is transitionally fitted with the outer ring of the third bearing M. In this way, the stability of the entire cleaning roller 202 driven by the output shaft 14 in high-speed rotation can be increased, and the noise of the entire cleaner during operation can be reduced. The inner cylinder of the cleaning roller 202 is rotatably connected to the outer periphery of the hinge part 23 at one end of the hinge 2, and together with the end knob assembly 3, it realizes the rotation support of the cleaning roller 202 inner cylinder with a larger spacing, which minimizes the radial runout generated during the rotation of the cleaning roller 202 inner cylinder, and ensures that the equipment runs with less noise.

[0110] In the embodiment of the present application, please refer to Figure 4 and Figure 5 As shown, the cleaning head housing 201 is provided with a clamping port 2012 at the corresponding position of the clamping end of the end knob assembly 3, and a wear-resistant ring (not marked in the drawing) is arranged inside the clamping port 2012. The arrangement of the wear-resistant ring reduces the wear of the clamping end of the end knob assembly 3 by the clamping port 2012.

[0111] In the embodiment of the present application, please refer to Figure 12 、 Figure 13 The cleaning roller 202 includes an inner cylinder 2021, an outer cylinder 2022, and a coupling part 2023. The inner cylinder and the outer cylinder can be axially slidably detached and separated from each other. The coupling part 2023 is arranged at one end of the inner cylinder 2021, and the coupling part 2023 and the inner cylinder 2021 are in interference fit or bonded with each other. A sponge layer (not shown in the drawing) for scrubbing the surface to be cleaned is wrapped around the outer edge of the outer cylinder 2022. Regular grooves (not shown in the drawing) are arranged between the inner cylinder 2021 and the outer cylinder 2022. The cross section of the regular grooves can be V-shaped, T-shaped, I-shaped, L-shaped, M-shaped, H-shaped, P-shaped, etc. In the tangential direction of the outer edge of the cleaning roller 202, the inner cylinder 2021 and the outer cylinder 2022 will not slide relative to each other. The inner cylinder 2021 rotates synchronously with the outer cylinder 2022. During operation, the end knob assembly 3 drives the coupling part 2023 to rotate, and further drives the outer cylinder 2022 to rotate through the inner cylinder 2021. The scrubbing layer of the outer cylinder 2022 scrubs the surface to be cleaned.

[0112] The coupling part 2023 is arranged at one end of the inner cylinder 2021, and is in interference fit or bonded with the inner cylinder 2021, so that mutual sliding and rotation between the two is not easy to occur. The coupling part 2023 is coupled with the clamping part 322 of the end knob body 32, and when the end knob body 32 rotates, the coupling part 2023 is driven to rotate synchronously, and then the entire cleaning roller 202 is driven to rotate. The coupling part 2023 is arranged at one end of the inner cylinder 2021, so that the external rotating driving mechanism can conveniently drive the entire cleaning roller 202 to rotate by coupling with one end of the cleaning roller 202.

[0113] The cleaning roller 202 is worn by the wiping layer on the outer surface after being used for a period of time, and when the wear degree seriously affects the cleaning efficiency, the outer cylinder 2022 of the cleaning roller 202 needs to be replaced. The design that the inner cylinder 2021 and the outer cylinder 2022 can be quickly disassembled and replaced reduces the maintenance cost of the user when the cleaning roller 202 is replaced, and only the outer cylinder 2022 with the wiping layer needs to be replaced. The design that the inner cylinder 2021 and the outer cylinder 2022 can be axially slidably disassembled and separated improves the convenience and replacement efficiency of the outer cylinder 2022, improves the user experience, and reduces the difficulty of the user to replace the outer cylinder 2022.

[0114] In the embodiment of the application, please refer to Figure 12 、 Figure 13 , the cleaning roller 202 includes a driving coupling end 202A and a driven end. The driving coupling end 202A is coupled with the end knob assembly 3 through the coupling part 2023, and the driven end is rotatably connected with the hinged piece 2 through the third bearing M. In this way, the stability of the entire cleaning roller 202 driven by the end knob assembly 3 in high-speed rotation can be improved, and the noise of the entire cleaner during operation can be reduced. The inner cylinder 2021 of the cleaning roller 202 is rotatably connected with the outer periphery of the hinged piece 2 at one end of the hinged piece 2, and together with the end knob assembly 3, the inner cylinder 2021 of the cleaning roller 202 is rotatably supported at a large distance, so that the radial runout generated during rotation of the inner cylinder 2021 of the cleaning roller 202 is minimized, and the noise of the equipment during operation is ensured to be small.
