After the completion of the mopping, the felt cloth can be disassembled from the rubbing block and then cleaned.

[0078] Example 3

[0079] A back-and-forth reciprocating-type mop is provided, including a handle device 2, a handle lever device 3, an upper cover portion 5 as part of a housing, a bottom case portion 12 as part of the housing, and a rubbing device 16 configured to rub a surface to be cleaned for the purpose of cleaning the same. As an extension of the handle, the handle lever device 3 can be designed to be adjustable in length by considering the degree of comfort of a user operating the mop, or the length of the handle lever device 3 is fixed by taking an average height of the adults as a reference length. In this embodiment, the upper cover portion and the bottom case portion can be independent or a corresponding portion of a housing in an integrated design or a split design.

[0080] Most of control switches are concentrated on the handle device 2 and in wired or wireless connection to the components in the housing and control the components. The handle can be provided with one or all of the following: a switch configured to control a main motor device 10, a switch configured to control a water injection motor 8, a battery charge interface, and a water inlet of a water storage device 7. The housing is a portion for wrapping the main motor device 10, an eccentric connection device, the water injection motor 8, the water storage device 7 and part of the sliding connection devices. Of course, if possible, a smaller height of the housing is applicable to a larger variety of furniture and more application scenarios.

[0081] Wherein, the bottom case portion 12 includes a main motor device 10, an eccentric connection device, a water injection motor device 8 and a water storage device 7;

[0082] the main motor device 10 is connected to the eccentric connection device;

[0083] the rubbing device 16 includes a sliding connection device, and an eccentric

connection device connected to the sliding connection device;

[0084] the rubbing device 16 is mounted on the sliding connection device and driven by the eccentric connection device to do reciprocating motion;

[0085] the upper cover portion 5 is located at a portion of the bottom case portion 12 above the rubbing device 16;

[0086] the upper cover portion 5 is connected to the handle device 2 by the handle lever device 3; and

[0087] the bottom case portion 12 further includes a water injection nozzle 11 provided at a front end from the perspective of a user.

[0088] Further, a piece of felt cloth is provided in a portion of the rubbing device 16 facing a surface to be cleaned; wherein the felt cloth is sleeved on the rubbing device 16 or stuck on the rubbing device 16, or by similar connection modes, for example, the felt cloth is fixed on the bottom of the rubbing device 16 by nails.

[0089] Further, as shown in Fig. 5 and Fig. 6, the difference from the above embodiments is that the rubbing device 16 may have an arc-shaped bottom surface rather than a planar bottom surface, in order to adapt to some dirty places. In this case, the felt cloth can be utilized as much as possible, and dust or stains can be struck on the felt cloth as evenly as possible.

[0090] Moreover, as a noise-isolating device 6, in addition to the noise enclosure mentioned in the above embodiments, soft noise-isolating materials such as noise-isolating cotton wrapped around the main motor device 10 should also be included. Meanwhile, silencing components such as a silencing mat should be provided at the main motor device 10 and other components, such as a joint of the housing.

[0091] A water injection outlet is provided at a front end of the housing, and the "front end" means an end in front of the working direction of the mop.

[0092] In order to reduce the height of the mop housing, the main motor device 10 and the water injection motor device 8 are in transverse arrangement, and the "transverse arrangement" refers to an arrangement generally perpendicular to or at least forming a crossing angle with the advancing path of the mop. The main motor device 10 and the water injection motor device 8 are coaxially arranged, or at least central axes of the two are in the same direction. Moreover, the water storage device 7 may be provided between the two motors, and designed to be substantially elongated and the extension direction of the elongated length is consistent with or identical to the advancing path of the mop. As described in the above embodiments, the eccentric connection device includes an eccentric wheel 17 connected to the main motor device 10 and an eccentric connection rod 9 connected to an eccentric shaft of the eccentric wheel 17, but the length direction of the eccentric connection rod 9 is set to be consistent with the advancing path of the mop. When the above structures are applied to the mop of this embodiment, the height of the mop housing is greatly reduced. Similar but less significant effects can be achieved by applying only part of the above structures to the mop of this embodiment.

[0093] Finally, as a connection mechanism of the rubbing device 16, the sliding connection device includes at least one sliding support and at least one connecting support which are fixedly connected to the rubbing device 16; wherein the rubbing device 16 slides on the sliding support; and one end of the connecting support is fixedly connected to the rubbing device 16, and the other end thereof is connected to the eccentric connection device. The sliding support and the connecting support are separately arranged, which means that the sliding support and the connecting support are not connected directly. In this embodiment, such an arrangement is provided to improve the stability and also reduce part of vibration. The number of the connecting support and sliding support can be increased appropriately, and there is one connecting support and two sliding supports in this embodiment. The appropriate increase in the number of connecting support and the sliding support can enable the stress to be distributed more evenly. The slider racks include a combination of a slide rail 14 and a slide block 13 which are respectively connected to the rubbing device 16 and the bottom case portion 12 of the housing.

[0094] In conclusion, the above description is merely some preferred Example of the present invention, all the equivalent variations and modifications made in accordance with the scope of the invention patent should belong to the scope of the invention patent.
