Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, in particular to a cleaning mechanism for a cleaning machine and the cleaning machine. Background Art

[0002] There are many types of cleaning machines in the prior art. For example: a sweeper that only sweeps the floor, a mopper that only mops the floor, and a sweeper-mopper integrated machine that combines the functions of sweeping and mopping.

[0003] In order to realize the mopping function of the cleaning machine, in the prior art, a mop structure is usually configured at the bottom of the cleaning machine. For example: the Chinese utility model patent "A crawler-type cleaning mechanism, cleaning device, and sweeper" with the patent number ZL202020457484.3 (the authorized announcement number is CN213097715U), and another example is the Chinese utility model patent "Mop assembly and cleaning robot" with the patent number ZL202120113848.0 (the authorized announcement number is CN214804444U). Both of the above two patents disclose a crawler-type mop structure.

[0004] On the one hand, since the crawler-type mop structures in the prior art are all in a ring shape, in order to realize the cleaning of the floor by the mop, the center of the transmission shaft of the crawler-type mop structure needs to be very close to the ground. Therefore, during the operation of the crawler-type mop structure, the driving component is extremely easy to collide with the ground, which will cause damage to the driving component, affect the cleaning performance and obstacle-crossing ability of the crawler-type mop structure, and at the same time, it is very likely to cause damage to the ground and affect the user experience; on the other hand, the crawler-type mop structure in the prior art is limited by the horizontal space of the cleaning machine, the area of the mop is limited, and it is difficult to change the area of the mop, thereby improving the cleaning power. Therefore, in order to improve the cleaning power, it is necessary to increase the running speed of the crawler-type mop structure. However, due to the increase in speed, the driving mechanism will generate serious heat and consume a large amount of power. Therefore, further improvement of the prior art is needed. Summary of the Utility Model

[0043] The present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0044] The cleaning machine in this embodiment is a mopping machine or a mopping and sweeping integrated machine. As Figures 1 to 11As shown in the figure, the cleaning machine in this embodiment includes a cleaning mechanism, and the cleaning mechanism includes a mop assembly. The mop assembly includes a driving shaft 1, a driven shaft, and a mop 2 wound around the circumferential walls of the driving shaft 1 and the driven shaft. In this embodiment, there are at least two driven shafts. Two of the driven shafts are denoted as the first driven shaft 31 and the second driven shaft 32. The first driven shaft 31 and the second driven shaft 32 are arranged at intervals along the traveling direction of the cleaning machine. The position where the driving shaft 1 is located is higher than the position where the first driven shaft 31 and / or the second driven shaft 32 are located.

[0045] Taking the traveling direction of the cleaning machine as the front, the driving shaft 1, the first driven shaft 31, and the second driven shaft 32 all extend along the left-right direction of the cleaning machine. And in order to keep the area in contact with the ground as large as possible, the first driven shaft 31 and the second driven shaft 32 are basically at the same height. Due to the assembly of the above-mentioned driving shaft 1, the first driven shaft 31, and the second driven shaft 32, the mop 2 can be basically triangular. As Figure 8 shown in the figure, in this embodiment, the driving shaft 1 is located directly above the first driven shaft 31, so the mop 2 is a right triangle. The driving shaft 1 is driven by a driving component a. In this way, the driving component a can be arranged above the mop 2, which can effectively avoid the problems of damage and obstacle-crossing ability caused by the driving component a being too close to the ground.

[0046] In addition, in order to make better use of space and compress the space occupied by the mop 2 as much as possible, a driven member (not shown in the figure) parallel to the driving shaft 1 is provided beside the driving shaft 1. The outer peripheral wall of the driven member can be in contact with the surface of the mop 2 to change the shape of the mop 2. As Figure 3 shown in the figure, by the driven member fitting the outer surface of the mop 2, the hypotenuse of the mop 2 is basically in an L shape, which improves the space utilization rate of the mop 2. The driven member in this embodiment can be a driven shaft or a driven component with an external arc. The purpose of the driven member is to realize the shape constraint of the mop 2, which will not be elaborated here.

[0047] As Figures 4 to 6 shown in the figure, the cleaning mechanism further includes a first bracket 4, a second bracket 5, and a first elastic member 6. The first bracket 4 is used for installing the driving shaft 1 and the first driven shaft 31. The second bracket 5 is arranged opposite to the first bracket 4 and is used for installing the second driven shaft 32. The first elastic member 6 is constrained between the second bracket 5 and the first bracket 4. The first elastic member 6 acts on the second bracket 5 to make the second bracket 5 always have a tendency to move away from the first bracket 4. The first elastic member 6 in this embodiment is a spring, and the spring is arranged along the traveling direction of the cleaning machine. In addition, there are at least two springs, and each spring is arranged at intervals along the extending direction of the second bracket 5. A recess 511 for constraining the first elastic member 6 is provided on the second bracket 5.

[0048] In addition, as Figure 1As shown, a cover body b having the same shape as the mop 2 is further installed on the first bracket 4. The cover body b covers the outer periphery of the mop 2 and has a gap with the outer surface of the mop 2. A collection bin c is further provided on the side of the cover body b away from the second driven shaft 32. The structure of the cleaning mechanism installed in the cleaning machine can refer to the prior art, such as the Chinese utility model patent "A crawler-type cleaning mechanism, cleaning device, and floor sweeper" with the patent number ZL202020457484.3 (the authorized announcement number is CN213097715U), and also such as the content disclosed in the Chinese utility model patent "Mop assembly and cleaning robot" with the patent number ZL202120113848.0 (the authorized announcement number is CN214804444U), which will not be elaborated here.

[0049] Both the first bracket 4 and the second bracket 5 extend along the left-right direction of the cleaning machine, and the first bracket 4 is detachably connected to the second bracket 5. In this embodiment, one of the first bracket 4 and the second bracket 5 has a first locking foot 51, and the other has a locking block 41. The locking block 41 has a clamping portion 411 for the first locking foot 51 to be clamped, so as to realize the detachable connection between the first bracket 4 and the second bracket 5 through the cooperation of the first locking foot 51 and the clamping portion 411. As Figure 4 and Figure 5 shown, there are two locking blocks 41, which are respectively arranged at both ends of the second bracket 5. Correspondingly, there are also two first locking feet 51. In this embodiment, the first locking foot 51 is arranged on the second bracket 5, and the locking block 41 is arranged at the end of the first bracket 4. The locking block 41 is provided with an insertion hole 414 for the first locking foot 51 to be inserted therein, and the clamping portion 411 is arranged inside the locking block 41.

[0050] In order to facilitate the disassembly and assembly of the mop and keep the mop in a taut state during work, the locking block 41 is constrained on the first bracket 4. A second elastic member 7 is arranged inside the first bracket 4. The second elastic member 7 acts on the locking block 41, so that the locking block 41 always has a tendency to move towards the outer end of the first bracket 4, and further makes the first locking foot 51 always have a tendency to be clamped with the clamping portion 411. In this embodiment, the second elastic member 7 is also a spring, and the second elastic member 7 is arranged along the extending direction of the first bracket 4. In addition, the locking block 41 has a second locking foot 412. A long slot 413 is opened on the first bracket 4 along the extending direction of the first driven shaft 31. The second locking foot 412 can move along the extending direction of the long slot 413, and the second locking foot 412 is clamped on the groove wall of the long slot 413, thereby realizing the constraint of the locking block 41 on the first bracket 4.

[0051] As Figure 4 and Figure 5As shown, one of the first bracket 4 and the second bracket 5 is provided with a first limiting component 8, and the other has a second limiting component 9 that can be adapted to the first limiting component 8, so that the first bracket 4 and the second bracket 5 are kept stable. The first limiting component 8 in this embodiment includes two protrusions 81 distributed left and right and a limiting block 82 arranged between the two protrusions 81. Correspondingly, the second limiting component 9 includes grooves 91 adapted to each protrusion 81 and a limiting groove 92 adapted to the limiting block 82. The grooves 91 are used for the corresponding protrusions 81 to be inserted, and the limiting groove 92 is used for the limiting block 82 to be inserted. The assembly of the first limiting component 8 and the second limiting component 9 can be as Figure 7 , Figure 9 and Figure 11 shown. As Figure 11 shown, the protrusion 81 is a right trapezoid, and a trapezoidal recess is formed between the two protrusions 81.

[0052] In this embodiment, the state of the mopping component in Figure 3 is recorded as the first state. As Figure 7 shown, it is a cross-sectional view of the mopping component in the first state; the state of the mopping component in Figure 8 is recorded as the second state. As Figure 9 shown, it is a cross-sectional view of the mopping component in the second state; the state of the mopping component in Figure 10 is recorded as the third state. As Figure 9 shown, it is a cross-sectional view of the mopping component in the third state.

[0053] In the first state, as Figure 7 shown, the first latch 51 on the second bracket 5 is inserted into the jack 414, but the first latch 51 is not latched on the latching portion 411; as Figure 3 shown, the mopping cloth 2 changes its shape under the action of the driven member to ensure the transmission efficiency and reduce the crosstalk of the mopping cloth;

[0054] In the second state, the driven member is disassembled. As Figure 8 shown, at this time, the mopping cloth 2 changes from the shape in the first state to a triangular shape; as Figure 9 shown, the first latch 51 on the second bracket 5 is not inserted into the jack 414, so that the mopping cloth 2 can be kept in a taut state to avoid the mopping cloth falling off during storage, transportation and other states.

[0055] In the third state, an external force can push the second bracket 5 in the second state towards the first bracket 4, so that the first latch 51 is inserted into the jack 414 and the first latch 51 is latched on the latching portion 411. At this time, the mopping cloth 2 becomes loose. As Figure 11 shown, this can facilitate the removal of the mopping cloth 2.

[0056] In this embodiment, the disassembly and assembly process of the mop assembly is as follows:

[0057] First, after replacing the mop 2 in the third state, press the two locking blocks 41. The two locking blocks 41 both move inward. At this time, the first locking feet 51 will be separated from the engaging portion 411, and the second bracket 5 will move away from the first bracket 4 under the action of the first elastic member 6, and the mop assembly becomes the second state. Then, install the driven member in the second state, and the mop assembly changes from the second state to the first state, that is, the assembly of the mop assembly is completed. On the contrary, the mop assembly changes from the first state to the second state, and then from the second state to the third state, that is, the disassembly and replacement of the mop assembly are realized.
