Description

[0001] This application is a divisional application of Chinese Patent Application No. 202323591466.7, with an application date of December 27, 2023, and an invention title of "A Detachable Electric Drive Device and a Cleaning Machine", the content of which is incorporated herein by reference. Technical Field

[0002] The utility model relates to the technical field of cleaning equipment, in particular to a detachable electric drive device and a cleaning machine. Background Art

[0003] In the prior art, an inner cylinder is provided in the outer cylinder of the cleaning roller of a floor washer, and the motor in the inner cylinder is powered by a power cord introduced from an end that is hinged to the cleaning head at one end of the inner cylinder. Since this end is hinged to the cleaning head, the end cannot be detached from the cleaning head together with the cleaning roller. At the same time, since the power cord passes through the end, when completely detaching the cleaning head to repair the drive motor, it is necessary to cut the power cord to completely separate from the cleaning head, and when reinstalling after the repair, it is necessary to reconnect the cut power cord, and the disassembly and assembly during the repair process are rather troublesome and other problems.

[0004] In the prior art, the motor sleeved inside the cleaning roller only drives the cleaning roller itself to work and cannot drive other components to work additionally.

[0005] In the prior art, since the wiping layer on the outer surface of the cleaning roller is worn to a certain extent after being used for a period of time, when the degree of wear seriously affects the cleaning efficiency, the entire cleaning roller needs to be replaced. Since the current manufacturing process of the cleaning roller is relatively complex, it is impossible to quickly maintain and replace only the wiping layer of the cleaning roller, but the entire cleaning roller needs to be replaced.

When the end cap 33 is pushed by the elastic force of the telescopic cap spring 34 to drive the telescopic cap 35 to drive the end cap 33 to be snapped into the snap - in position of the cleaning head housing 201, the driving tooth on the outer peripheral wall of the end cap is sleeved into the inner ring of the driven gear N. When the driving motor 12 built in the electric drive assembly 1 operates, it drives the output shaft 14 to rotate, thereby driving the cleaning roller 202 to rotate and simultaneously driving the driven gear N to rotate, and then driving the brush assembly to rotate. A part of the outer edge of the end cap 33 at the snap - in end of the end button assembly 3 is sleeved with the driven gear N. The snap - in end is snap - connected to the other side wall of the cleaning head housing and has a movement stroke along the axial direction of the electric drive assembly 1. The driven gear N drives the brush assembly to rotate, further saving the installation space of the motor required to additionally configure the drive for the brush assembly to rotate, and also further reducing the noise during the operation of the cleaner.

[0105] In the embodiment of the present invention, please further refer to Figure 9 , Figure 10 , Figure 15 and Figure 16 , a rotational connection between the inner peripheral wall of the end button mounting seat 31 and the outer peripheral wall of the output shaft socket end 321 of the end button body 32 is realized through the first bearing 311. The inner peripheral wall of the end button mounting seat 31 is in transitional fit with the outer ring of the first bearing 311, and the outer peripheral wall of the output shaft socket end 321 is in transitional fit with the inner ring of the first bearing 311. This can increase the stability of the entire end button assembly 3 driven by the output shaft 14 during high - speed rotation and also reduce the noise during the operation of the entire cleaner.

[0106] Specifically, in the embodiment of the present invention, as shown in Figure 9 , Figures 14 to 18 , the electric drive assembly 1 includes: a motor heat - conducting protection cylinder 10 and a driving motor 12, a speed - changing device 13 and an output shaft 14 which are sequentially coupled and accommodated therein. The motor heat - conducting protection cylinder 10 is preferably made of a metal material. The motor heat - conducting protection cylinder 10 can be directly attached to the outer shell of the driving motor 12 or the heat dissipation of the outer shell of the driving motor 12 can be achieved by filling the gap with heat - conducting silicone grease. The arrangement that each unit of the electric drive assembly 1 is accommodated in the motor heat - conducting protection cylinder 10 preferably ensures that each unit of the electric drive assembly 1 is not easily polluted by dust and water vapor, and improves the reliability of the use of each unit of the electric drive assembly 1.

[0107] In the embodiment of the present utility model, as Figure 10 , Figure 15 , Figure 16 , Figure 18 shown, an output end seal plug 141 is provided at a corresponding position on the inner wall of the motor heat conduction protection cylinder 10 around the outer circumference of the output shaft 14. The setting of the output end seal plug 141 further ensures the dust-proof property of the electric drive assembly 1.

[0108] In a second aspect, the embodiment of the present utility model further provides a cleaning machine 200, which includes a cleaning head housing 201, a cleaning roller 202, and the detachable electric drive device 100 described in the first aspect. The cleaning head housing 201 has a motor fixing part 2011, which is hinged to the first end of the hinge member 2, and the second end of the hinge member 2 is detachably electrically connected to the power connection end 1a of the electric drive assembly 1; the cleaning roller 202 is driven to rotate by the rotation output end 1b of the terminal button assembly 3. Since the cleaning machine 200 adopts all the technical solutions of the detachable electric drive device 100 described above, it correspondingly has the corresponding technical effects, which will not be elaborated here.

[0109] Specifically, in the embodiment of the present utility model, as Figures 6 to 9 shown, the motor fixing part 2011 includes a fixing part body 20111, a hinge head receiving cavity 20112 and a wire harness receiving cavity 20113 opened on the fixing part body 20111. A pin hole 20114 is opened on the side wall of the hinge head receiving cavity 20112 for cooperating with a hinge pin 20115 to be hinged to the corresponding hinge member 2, and the wire harness receiving cavity 20113 is used for the wire harness led out by the hinge member 2 to pass through.

[0110] Specifically, in the embodiment of the present utility model, 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 a position corresponding to the pin hole 20114. The setting of the annular clearance step 20116 enables a large activity space at the hinged position between the fixing part body 20111 and the hinge member 2, avoiding inconvenient rotation when the fixing part body 20111 and the hinge member 2 are hinged and rotated during the disassembly of the detachable electric drive device 100, and improving the convenience of disassembly.

[0111] Specifically, in the embodiment of the present utility model, as Figure 9 , Figure 11 , Figure 15 , Figure 16 and Figure 18As shown, the inner cylinder of the cleaning roller 202 is rotatably connected between one end of the hinge member 2 and the outer periphery of the motor fixing portion 2011 through a third bearing M. The inner peripheral wall of the cleaning roller 202 is in transitional fit with the outer ring of the third bearing M, and the outer peripheral wall of the motor fixing portion 2011 is in transitional fit with the inner ring of the third bearing M. This can increase the stability of the entire cleaning roller 202 driven by the output shaft 14 during high-speed rotation and also reduce the noise of the entire cleaner during operation. The inner cylinder of the cleaning roller 202 is rotatably connected between one end of the hinge member 2 and the outer periphery of the hinge portion 23, together with the terminal assembly 3, to achieve rotational support for the inner cylinder of the cleaning roller 202 with a relatively large spacing, minimizing the radial runout generated during the rotation of the inner cylinder of the cleaning roller 202 and ensuring relatively low noise during equipment operation.

[0112] In the embodiment of the present invention, please refer to Figure 4 and Figure 5 As shown, at the corresponding position of the clamping end of the terminal assembly 3 on the cleaning head housing 201, there is a clamping interface 2012, and a wear-resistant ring (not marked in the drawing) is provided inside the clamping interface 2012. The setting of the wear-resistant ring reduces the wear of the clamping end of the clamping interface 2012 on the terminal assembly 3.

[0113] In the embodiment of the present invention, please refer to Figure 12 , Figure 13 , the cleaning roller 202 includes an inner cylinder 2021, an outer cylinder 2022, and a coupling portion 2023; the inner cylinder and the outer cylinder can be slidably detached and separated along the axial direction, the coupling portion 2023 is provided at one end of the inner cylinder 2021, and an interference fit or bonding is provided between the coupling portion 2023 and the inner cylinder 2021; a sponge layer (not marked in the drawing) for scrubbing the surface to be cleaned is coated on the outer edge of the outer cylinder 2022. Regular grooves (not marked in the drawing) are provided between the inner cylinder 2021 and the outer cylinder 2022, and the equal cross-section of the regular grooves can be regular shapes such as V-shaped, T-shaped, I-shaped, L-shaped, M-shaped, H-shaped, P-shaped, etc. Along the tangential direction of the outer edge of the cleaning roller 202, no relative sliding occurs between the inner cylinder 2021 and the outer cylinder 2022, and the inner cylinder 2021 drives the outer cylinder 2022 to rotate synchronously. During operation, the terminal assembly 3 drives the coupling portion 2023 to rotate, and further drives the outer cylinder 2022 to rotate through the inner cylinder 2021, and the wiping layer of the outer cylinder 2022 scrubs the surface to be cleaned.

[0114] The coupling part 2023 is arranged at one end of the inner cylinder 2021. The coupling part 2023 and the inner cylinder 2021 are in interference fit or bonded to each other, so that it is not easy for them to slide and rotate relative to each other. The coupling part 2023 is coupled with the clamping part 322 of the terminal body 32. When the terminal body 32 rotates, it drives the coupling part 2023 to rotate synchronously, and then drives the entire cleaning roller 202 to rotate. The coupling part 2023 is arranged at one end of the inner cylinder 2021, which can facilitate the external rotation driving mechanism to drive the entire cleaning roller 202 to rotate by coupling one end of the cleaning roller 202.

[0115] Since the wiping layer on the outer surface of the cleaning roller 202 is worn to a certain extent after being used for a period of time, when the degree of wear seriously affects the cleaning efficiency, the outer cylinder 2022 of the cleaning roller 202 needs to be replaced. This 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 replacing the cleaning roller 202. 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 slid axially relative to each other and disassembled and separated improves the convenience and efficiency of replacing the outer cylinder 2022, enhances the user experience, and reduces the difficulty for the user to replace the outer cylinder 2022 by himself.

[0116] In the embodiment of the present utility model, 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 terminal assembly 3 through the coupling part 2023, and the driven end is rotatably connected with the hinge member 2 through the third bearing M. This can increase the stability of the entire cleaning roller 202 driven by the terminal assembly 3 during high-speed rotation, and also reduce the noise of the entire cleaner during operation. The inner cylinder 2021 of the cleaning roller 202 is rotatably connected to the outer periphery of the hinge member 2 at one end of the hinge member 2, and together with the terminal assembly 3, it realizes the rotational support of the inner cylinder 2021 of the cleaning roller 202 with a relatively large spacing, minimizing the radial runout generated during the rotation of the inner cylinder 2021 of the cleaning roller 202 and ensuring the relatively low noise of the equipment operation.
