Description

Detachable motor driving device and cleaner

Technical Field

The utility model belongs to the field of cleaning cleaners, and particularly relates to a detachable motor driving device and a cleaner.

Background

With the development of modern technology, floor cleaning tools are widely used, including brooms, mops, floor wipers, dust collectors, and the like. The cleaner is a very conventional floor cleaning tool, but the cleaner is very noisy and uncomfortable. And the cleaning mode of the garbage is just to suck the garbage into the garbage box.

Broom, mop, floor brush are of the type of cleaning tools that generally have a fixed cleaning section with a cleaning capacity that is determined by the dirt removal and suction capacity of the cleaning section. Since the cleaning portion is contaminated upon contact with the soiled floor, the cleaning ability is gradually reduced during the subsequent cleaning process, and particularly when the cleaning is continuously performed over a large area, thorough cleaning is not possible. Therefore, the cleaning products must be rinsed frequently, which is very troublesome. The cleaning in the prior art uses a drum motor as a drum driving part of the sweeping robot, for example, in the sweeping robot.

The floor washing machine adopts clear water to infiltrate the cleaning roller and then uses the cleaning roller to clean the floor to be cleaned, has the advantage of low noise on a technical route compared with dust collector products, has the advantage of cleaning the cleaning roller in real time compared with the traditional mop, and is accepted by common consumers more and more.

The floor washer mainly drives the roller to rotate through motor driving so as to clean the ground, the corresponding motor is fixedly connected with a side plate of the floor washer towing head, the fixed end part of the motor and the side plate is provided with a grounding wire which is electrically connected with a circuit which is connected with the power supply device and is arranged in the side plate, and therefore the motor is driven to work; when the floor washing machine cannot work due to the motor, a user cannot maintain the floor washing machine by himself, the whole floor washing machine is required to return to a factory, and the after-sale cost of the product is increased; in addition, because the motor is electrically connected with the internal circuit of the floor washing machine body, the motor can be realized after the electric wires are cut off and the screws are disassembled when the motor is replaced, and meanwhile, the motor is required to be rewiring and assembled when the motor is replaced, so that the workload of maintenance personnel is increased, and meanwhile, long-term benign maintenance of products is not facilitated.

On the other hand, even if the waiting time in the repair process of returning to the factory is reduced, after the customer receives the standby motor, when the roller motor needs to be replaced, the user needs to detach the roller motor from the fixing structure such as the screw on the cleaner frame, and after the roller is repaired or cleaned or replaced, the roller motor is installed according to the process, so that the whole detachment process is complicated, and the detachment experience is poor. Similarly, when the drum is required to be mounted on the drum motor, the existing floor washer products on the market slide out of one end of the drum assembly from one side of the cleaning head after being pressed by a button at one end of the drum assembly, then slide out of the cleaning drum along the direction of the drum wall of the motor after rotating around a rotating shaft at the other end of the cleaning head along the built-in motor, the disassembling process is very complicated, the operation is required to be performed in a specific direction of the cleaning head of the floor washer, and the user is inconvenient to replace or maintain by himself.

When the roller motor of the existing cleaning machine needs to be replaced or the roller is required to be installed on the roller motor, a user needs to detach the roller motor from a fixing structure such as a screw on a cleaning appliance frame, a power line of the motor needs to be cut off, the roller motor is installed according to the previous process after maintenance or cleaning or roller replacement, the power line needs to be welded again, the whole detaching process is complex, and the detaching experience is poor.

In order to solve the above problems, the present utility model proposes a detachable motor driving device 100 for a cleaner, referring to fig. 1, 6, 15, 16, 17, 18, 19, and 20 in an embodiment of the present utility model, the detachable motor driving device 100 includes: the electric cleaning device comprises a fixed cylinder 1, an electric driving module 2, a transmission output piece 3 and two clamping pieces 4, wherein the electric driving module 2 is installed in the fixed cylinder 1, the rotation output end of the electric driving module 2 is in transmission connection with the transmission output piece 3, the transmission output piece 3 is used for driving a driven device 200 with a transmission receiving piece 201 to rotate, the two clamping pieces 4 are respectively arranged at two ends of the fixed cylinder 1, and the whole clamping piece 4 is provided with an elastic stroke extending and contracting along the axial direction of the fixed cylinder 1 and is used for being detachably connected with a cleaner shell 300.

It should be noted that the detachable connection may be a plug connection or an elastic clip connection; when the detachable connection is in plugging connection, the two clamping pieces 4 can be arranged into a telescopic cylinder shape through the clamping pieces 4 and are inserted into the jack of the cleaner shell 300, so that the whole clamping pieces 4 have elastic travel stretching along the axial direction of the fixed cylinder 1, and the elastic clamping can be arranged into cantilever clamping buckles through the clamping pieces 4 and matched with clamping grooves of the cleaner shell 300, so that the whole clamping pieces 4 have elastic travel stretching along the axial direction of the fixed cylinder 1; the two clamping pieces 4 can be simultaneously spliced or simultaneously elastically clamped, and the two clamping pieces 4 can be respectively spliced and elastically clamped to realize that the whole clamping piece 4 has elastic travel stretching along the axial direction of the fixed cylinder 1. The driven device 200 may be a cleaning cylinder sleeved outside the fixed cylinder 1, the transmission receiving member 201 is disposed on a shaft sleeve of the cleaning cylinder, and the transmission receiving member 201 and the transmission output member 3 may be a plurality of forms such as a gear and a gear fit or a friction wheel fit.

It should be noted that the two clamping pieces 4 may adopt an elastic telescopic structure at the same time, or may adopt a rigid structure in which one clamping piece 4 is not telescopic, and another clamping piece 4 is an elastic telescopic structure or an elastic clamping structure, or may also adopt a rigid structure in which one clamping piece 4 is not telescopic, and another clamping piece 4 is an elastic telescopic structure or an elastic clamping structure.

When the detachable motor driving device 100 needs to be detached, the two clamping pieces 4 apply force to each other along the axial direction of the fixed cylinder 1, and the two clamping pieces 4 integrally shrink along the axial direction of the fixed cylinder 1, so that the detachable motor driving device 100 can be easily detached from the cleaner housing 300, and naturally, the driven device 200 mounted on the detachable motor driving device 100 can also be detached together at the moment; when in installation, the two clamping pieces 4 of the detachable motor driving device 100 can be directly clamped into the corresponding positions of the machine shell, the disassembly and the assembly are convenient, the specific forms of the two clamping pieces 4 are not limited to the forms shown in the drawings, and the two clamping pieces can also be adapted according to the specific structure of the cleaning machine, and the utility model also belongs to the protection scope of the utility model.

The "force is applied to the two fixing members 4 in opposite directions along the axial direction of the sleeve 1" may be "force is applied to the telescopic cylinders of the two fixing members 4 in opposite directions along the axial direction of the sleeve 1" or "force is applied to the flexible cantilever snaps of the two fixing members 4 in a direction parallel to the axial direction of the sleeve 1" or "force is applied to the two points of elastic expansion and contraction of the telescopic cylinder of one fixing member and the cantilever snaps of the other fixing member" approximately parallel to the axial direction of the sleeve 1 ". In any of the above-listed manners, the distance between the fulcra of the two fixing members 4 clamped to the two side walls of the floor cleaning machine casing 300 is reduced, so that the motor detachable structure 100 can be conveniently removed from between the two side walls of the floor cleaning machine casing 300.

The detachable motor driving device 100 provided by the utility model adopts the transmission output piece 3 to output power to drive the driven device 200 with the transmission receiving piece 201 to rotate while the electric driving module 2 is arranged on the fixed cylinder 1, and two clamping pieces 4 which are detachably connected with the cleaner shell 300 and integrally have elastic travel extending and contracting along the axial direction of the fixed cylinder 1 are respectively arranged at two ends of the fixed cylinder 1. So that the cleaning machine formed by the detachable motor driving device 100 can take down the driving device from the cleaning machine shell through the two clamping pieces 4 conveniently in daily maintenance, the disassembly and assembly steps are simpler, and the daily maintenance disassembly and assembly experience of a user on the driving motor when using the cleaning machine is improved to a great extent.

Specifically, in order to ensure the reliability of the transmission output of the detachable motor driving device 100, in the embodiment of the present utility model, as shown in fig. 2, 3, 5, 7, 8, and 14, the transmission output member 3 is a latch member 3a rotatably mounted at one end of the fixed cylinder 1. It should be noted that, when the driven device 200 is a cleaning cartridge, the transmission receiving member 201 may be an annular latch slot member (not shown) that mates with the latch member 3a. The transmission output member 3 is selected as a latch member 3a, so that the detachable motor driving device 100 can synchronously output power to the driven device 200, and the latch member 3a is easy to cooperate with the transmission receiving member 201, so that the detachable motor driving device is convenient to install.

Specifically, referring to fig. 7 and 14, in this embodiment, the latch 3a includes a tooth shaft 3a1 and at least one latch plate 3a2 disposed on an outer peripheral surface of the tooth shaft 3a 1. When the plurality of teeth 3a2 are provided, they may be uniformly distributed along the circumferential direction of the tooth shaft 3a1, and the tooth shaft 3a1 may have a uniform diameter or may be provided in a stepped shaft shape as in the present embodiment. The latch plate 3a2 is configured to uniformly divide the output torque of the detachable motor driving device 100 and transmit the divided output torque to the driven device 200.

In order to facilitate the limitation of the driven device 200, in the embodiment of the present utility model, as shown in fig. 2 and 3, the transmission output member 3 is provided with a limiting sleeve 5, and the limiting sleeve 5 is mounted at one end of the latch member 3a away from the electric driving module 2 for limiting the driven device 200. The stop collar 5 can be screwed on the latch 3a and also can be clamped on the latch 3a, the stop collar 5 is convenient for limiting the driven device 200, the driven device 200 can be unlocked and removed from the detachable motor driving device 100 after the driven device 200 is removed along with the detachable motor driving device 100, and compared with the case that the driven device 200 is directly detached from the cleaner housing 300, the operation space is increased after the driven device 200 is removed along with the unlocking, and the driven device 200 such as the cleaning barrel can be disassembled and washed conveniently. The setting of the limit sleeve 5 not only can ensure the reliability of the unlocking driven device 200 and the rotation output of the driven device 200, but also is convenient to detach.

As a possible implementation manner, in order to facilitate the limitation of the driven device 200, in this embodiment of the present utility model, a hook and loop structure (not shown in the drawing) for limiting the driven device 200 is disposed on one side of the latch plate 3a2 of the transmission output member 3, a groove (not shown in the drawing) corresponding to the latch plate 3a2 in the transmission receiving member 201 of the driven device 200 is also disposed on the hook and loop structure (not shown in the drawing), a gap (not shown in the drawing) is disposed between the latch plate 3a2 and the groove, and when the transmission receiving member 201 of the driven device 200 is mounted in place along the axial direction of the latch plate 3a2, the hook and loop structure of the latch plate 3a2 can be firmly adhered together along the direction of the gap, so as to realize that the space for the axial movement of the driven device 200 is limited, and the driven device 200 cannot shake left and right in the axial direction during the high-speed rotation process. When the driven device 200 needs to be removed, the driven device 200 is only required to be rotated against the direction of the gap, so that the hook and loop fastener structure of the latch plate 3a2 is separated from the hook and loop fastener structure of the slot, and then the driven device 200 can be slowly taken out along the other side edge of the latch plate 3a2, on which the hook and loop fastener structure is not arranged.

As a possible implementation manner, in order to facilitate the limitation of the driven device 200, in an embodiment of the present utility model, as shown in fig. 8, a barb structure 3a3 for limiting the driven device 200 is disposed at the end of the latch plate 3a2 of the transmission output member 3, a gap (not shown in the drawing) is disposed between the latch plate 3a2 and a slot of the transmission receiving member 201 of the driven device 200, and when the transmission receiving member 201 of the driven device 200 is installed in place along the axial direction of the latch plate 3a2, the space for limiting the axial movement of the driven device 200 can be realized by rotating along the direction of the barb structure 3a by a certain angle, so that the driven device 200 cannot shake left and right in the axial direction during the high-speed rotation process. When the driven device 200 needs to be removed, the driven device 200 is only required to be rotated against the direction of the gap, so that the barb structure 3a3 of the latch plate 3a2 is separated from the groove, and then the driven device 200 can be slowly taken out along the other side edge of the latch 3a2, on which the barb structure 3a3 is not arranged.

In the embodiment of the present utility model, as shown in fig. 17, 18 and 19, one of the two fastening members 4 is a fixed socket 4a, and the inner end of the fixed socket 4a is mounted on the fixed socket 1 or mounted on the transmission output member 3, and the outer end extends out of the fixed socket 1 to cooperate with a jack (not shown in the drawings) of the cleaner housing 300 to achieve the detachable connection. It should be noted that, after one of the two clamping members 4 selects the fixed insertion tube 4a, the other one needs to select an elastic clamping member 4, such as a telescopic tube or an elastic arm, so as to realize that the whole of the two clamping members 4 has an elastic stroke extending and retracting along the axial direction of the fixed tube 1. One of the clamping pieces 4 is selected as a fixed insertion cylinder 4a, so that the integral production cost of the cleaner is reduced, and the economical efficiency of the detachable motor driving device 100 is improved.

In the embodiment of the present utility model, referring to fig. 5, 6 and 20, one of the two clamping members 4 is a fixed clamping cantilever 4b, the cantilever end of the fixed clamping cantilever 4b is elastically clamped with the cleaner housing 300, and the other end is mounted on the fixed cylinder 1. In this embodiment, the fixing clamping cantilever 4b is installed on the portion of the fixing barrel 1 and the cantilever portion may be integrally or separately assembled, and the fixing clamping cantilever 4b is configured so that the clamping member 4 is easier to elastically deform in the axial direction, so that the detachable motor driving device 100 can be easily removed from or clamped on the cleaner housing 300.

It should be noted that, even though the portion of the fixing and clamping cantilever 4b that is mated with the fixing cylinder 1 is made of an elastic material, the amount of expansion caused by the elastic material is limited, as shown in fig. 12, the distance between the fixing and clamping cantilever 4b and the other fixing element at the acting point between the two side plates of the floor cleaning machine casing 300 can be adjusted with greater adaptability under the elastic action of the thin-walled hanging lugs at the hanging lug portion (not shown in the drawing), where the elastic deformation is the result of the combined action of the elastic deformation of the portion of the fixing and clamping cantilever 4b that is mated with the fixing cylinder 1 and the elastic deformation of the hanging lug portion.

As the transmission output member 3 of the detachable motor driving device 100 needs to rotate, referring to fig. 5, 6, 14 and 20, in the embodiment of the present utility model, one of the two fastening members 4 is a rotation fastening cantilever 4c, and the cantilever end of the rotation fastening cantilever 4c is elastically fastened to the cleaner housing 300, and the other end is rotatably connected to the transmission output member 3. The rotary clamping cantilever 4c is sleeved with a bearing (shaft sleeve) 41, and the inner wall (not shown in the drawing) of the shaft of the transmission output member 3 is in transition fit with the bearing (shaft sleeve) 41. In the embodiment of the present utility model, the portion where the rotary clamping cantilever 4c is rotatably connected to the transmission output member 3 and the cantilever portion may be integrally or separately assembled, and the rotary connecting portion may be provided with a bearing or a shaft sleeve, and in order to prevent the bearing (shaft sleeve) 41 from falling off from the rotary clamping cantilever 4c, a clamp spring (not shown in the drawing) for stopping the bearing (shaft sleeve) 41 is further clamped thereon. The above arrangement of one of the clamping members 4 facilitates both the removal of the detachable motor drive device 100 from the cleaner housing 300 and the limitation of the transmission output member 3 when the detachable motor drive device 100 is mounted to the cleaner housing 300, thereby ensuring the reliability of transmission.

It should be noted that, even though the portion of the rotating clamping cantilever 4c that is mated with the sleeve 1 is made of an elastic material, the amount of expansion caused by the elastic material is limited, as shown in fig. 13, under the elastic action of the thin-walled hanging lugs, the distance between the fixed clamping cantilever 4b and the acting point of the other fixing piece between the two side plates of the floor cleaning machine shell 300 is adjusted with greater adaptability, and more, as shown in fig. 13, the axial center portion (not shown in the drawing) of the rotating clamping cantilever 4c is in transition fit with the bearing (shaft sleeve) 41, and under the action of an external force, the rotating clamping cantilever 4c can be adjusted with smaller axial displacement by virtue of the constraint of transition fit between the whole rotating clamping cantilever 4c and the bearing (shaft sleeve) 41, where the elastic deformation is the elastic deformation of the portion of the rotating clamping cantilever 4c that is mated with the sleeve 1, and the elastic deformation of the rotating clamping cantilever 4c that is in the axial direction of the joint cantilever 4c that is in the axial direction is in the joint with the bearing (shaft sleeve) and the joint bundle 41 is adjusted with smaller axial displacement by the joint result of the joint of the three.
