Patent Description:
At present, a cleaning machine is gradually widely used, which greatly facilitates household deep cleaning work and reduces intensity of people's household chores. However, after a floor brush of the cleaning machine works, a rolling brush of the cleaning machine is usually dirty and needs to be detached separately for cleaning. Although some cleaning machines can self-clean, these cleaning machines have an incomplete cleaning effect. Moreover, dirt occurs at a clean water outlet, so the rolling brush still needs to be disassembled to clean the floor brush.

When a floor scrubber cleans a corner of wall, due to limitation of a structure of the floor brush, flannelette on the rolling brush may not be in contact with wall edges and corners.

The reason why an existing cleaning apparatus has cleaning blind areas is that when a rolling brush is mounted on the existing cleaning apparatus, a drive motor is generally provided at an end of the rolling brush. In addition, in order to ensure rotation stability of the rolling brush, most cleaning apparatuses may also be provided with a rotary support structure at another end of the rolling brush. Therefore, a space at two ends of the rolling brush is occupied by the drive motor and the rotary support structure, creating a distance between the two ends of the rolling brush and two ends of the cleaning apparatus. This distance may result in the two ends of the rolling brush not extending beyond both ends of the cleaning apparatus at all, or even not being flush with the two ends of the cleaning apparatus. Therefore, when the cleaning apparatus is used for cleaning the ground, the blind areas at a distance between the two ends of the cleaning apparatus and the two ends of the rolling brush are unable to be cleaned, and the blind area has a size depending on a distance between an end portion of the rolling brush and an end portion of the cleaning apparatus. In order to solve this problem, the present invention provides the following technical solutions.

The floor brush <NUM> according to some embodiments of the present invention is described below with reference to <FIG>. The floor brush <NUM> in this embodiment may be applied in various cleaning apparatuses. In some embodiments, the cleaning apparatus may be a cleaning machine, a mopping machine, or a dry and wet dual-purpose vacuum cleaner.

With continued reference to <FIG>, the floor brush <NUM> in this embodiment includes a body <NUM>, a cover plate <NUM>, and a rolling brush <NUM>. The cover plate <NUM> defines a rolling brush accommodation cavity. The rolling brush <NUM> is rotatably disposed in the rolling brush accommodation cavity. The cover plate <NUM> is connected to the body <NUM>, and one end surface of the cover plate <NUM> is provided with a collar portion <NUM>. The cover plate <NUM> is connected to the rolling brush <NUM> to form an integrated structure. One end surface of the rolling brush <NUM> is recessed inwards to form a sleeve portion <NUM>, and another end surface of the rolling brush <NUM> is rotatably connected to another end surface of the cover plate <NUM>. The sleeve portion <NUM> is sleeved on the collar portion <NUM>, and the rolling brush <NUM> is rotatable relative to the collar portion <NUM>.

In some embodiments, the collar portion <NUM> is disposed on the one end surface of the cover plate <NUM>, and the one end surface of the rolling brush <NUM> is recessed inwards to form the sleeve portion <NUM> sleeved outside the collar portion <NUM>. In this way, a structure on the cover plate <NUM> for positioning the rolling brush <NUM> is retracted in the rolling brush <NUM>, which can save an external space of the rolling brush <NUM> occupied by the structure on the cover plate <NUM> for positioning the rolling brush <NUM>. Moreover, a space at the end portion of the rolling brush <NUM> is further vacated, allowing the end portion of the rolling brush <NUM> to extend to an exterior of the cleaning apparatus and realizing cleaning of an original blind area.

In this embodiment, with continued reference to <FIG>, the rolling brush <NUM> is provided with a rolling brush shaft <NUM> coaxially disposed with the sleeve portion <NUM>, and the rolling brush shaft <NUM> passes through the sleeve portion <NUM> to be rotatably connected to the collar portion <NUM>. In some embodiments, the collar portion <NUM> may function to position the rolling brush shaft <NUM>. When the rolling brush <NUM> is in a rotation state, the rolling brush shaft <NUM> is driven to rotate relative to the collar portion <NUM>. Therefore, it may be realized that the rolling brush <NUM> rotates relative to the collar portion <NUM>.

Further, with continued reference to <FIG>, the floor brush <NUM> further includes a limiting support member <NUM>, and the rolling brush shaft <NUM> is connected to the collar portion <NUM> through the limiting support member <NUM>. In some embodiments, the limiting support member <NUM> is selected from a bearing or a shaft sleeve assembly. When the limiting support member <NUM> is selected from the bearing, the bearing has an inner ring sleeved on the rolling brush shaft <NUM> and an outer ring connected to the collar portion <NUM>. When the limiting support member <NUM> is selected from the shaft sleeve assembly, the shaft sleeve assembly is connected to the collar portion <NUM> and is sleeved on the rolling brush shaft <NUM>.

In this embodiment, with continued reference to <FIG>, the collar portion <NUM> is disposed on an inner side end surface of the cover plate <NUM>. At this time, a metal inserter, as the collar portion <NUM>, may be provided on an inwardly recessed inner side surface of the cover plate <NUM>, which can enhance intensity of the inner side end surface of the cover plate <NUM> and make it lighter and thinner. Therefore, a blind area clean distance between the end surface of the rolling brush <NUM> and the wall edges can be greatly reduced, and a cleaning effect of the floor brush along the wall edges is effectively improved.

As illustrated in <FIG>, the collar portion <NUM> in this embodiment is of a cylindrical shape and is internally provided with a rotary shaft mounting base 110a. An end portion of the rolling brush shaft <NUM> is connected to the rotary shaft mounting base 110a. In some embodiments, the rotary shaft mounting base 110a has a mounting hole formed thereon. Moreover, a plurality of reinforcing ribs 110b is provided between the rotary shaft mounting base 110a and an inner cylinder wall of the collar portion <NUM>. In this way, support strength of the rotary shaft mounting base for the rolling brush shaft <NUM> can be increased.

The integrated structure is detachably connected to the body <NUM>. Herein, the cover plate <NUM> is slidably connected to the body <NUM>. The body <NUM> is provided with a sliding rail. The cover plate <NUM> is provided with a sliding member <NUM>, and the sliding member <NUM> is slidably inserted to the sliding rail. It should be noted that the sliding rail and the sliding member <NUM> both extend in an axial direction of the rolling brush <NUM>. In this way, when the integrated structure formed by the cover plate <NUM> and the rolling brush <NUM> is removed, the sliding member <NUM> slides out of the body <NUM> along the sliding rail in the axial direction of the rolling brush <NUM>. The integrated structure formed by the cover plate <NUM> and the rolling brush <NUM> may also be directly flipped horizontally to be removed.

In other embodiments of the present invention, the integrated structure may also be connected to the body <NUM> through other detachable manners. Through a detachable connection between the integrated structure and the body <NUM>, it can realize easy assembly and disassembly of the integral structure, and decrease disassembly steps.

Further, with continued reference to <FIG> and <FIG>, the floor brush <NUM> further includes a locking mechanism, and the locking mechanism is configured to lock or unlock sliding between the sliding rail and the sliding member <NUM>. In this embodiment, the locking mechanism has a locking groove <NUM> formed on the body <NUM> and a locking portion <NUM> disposed on the cover plate <NUM>. Moreover, the locking portion <NUM> is engageable into or disengageable from the locking groove <NUM>. In some embodiments, the locking portion <NUM> may be an unlocking button disposed on the cover plate <NUM>. When the rolling brush <NUM> needs to be disassembled, a side of the unlocking button is held by user's hand to press the unlocking button for unlocking it, and the integrated structure formed by the rolling brush <NUM> and the cover plate <NUM> is pulled out horizontally from the sliding rail on the body.

In another embodiment of the present invention, the locking portion <NUM> may also be disposed on the body <NUM>, and the locking groove <NUM> is formed on the cover plate <NUM>. The details of this embodiment are omitted here.

In addition, the locking mechanism may further include a snapping groove disposed on the body <NUM> and a snap disposed on the cover plate <NUM>. In some embodiments, the body <NUM> and the cover plate <NUM> are locked or unlocked through an engagement between the snap and the snapping groove. The snap may also be disposed on the body <NUM>, and the snapping groove is formed at a corresponding position of the cover plate <NUM>. In this way, locking or unlocking can be realized through the engagement between the snap and the snapping groove.
