A floor brush 100 for a vacuum cleaner according to an embodiment of the present invention will be described with reference to fig. 1 to 17.

As shown in fig. 1 to 17, a floor brush 100 for a vacuum cleaner according to an embodiment of the present invention includes: a ground brush base 1 and a rolling brush body 3.

In particular, the floor brush base 1 defines a rolling brush chamber. The rolling brush body 3 is rotatably provided in the rolling brush cavity, the floor brush 100 has a first cleaning mode and a second cleaning mode, the first cleaning mode and the second cleaning mode are suitable for cleaning different working surfaces (such as carpet or floor, etc.), the rolling brush body 3 at least comprises a first rolling brush body 31 and a second rolling brush body 32 which are interchangeable, the first rolling brush body 31 is suitable for working in the first cleaning mode, and the second rolling brush body 32 is suitable for working in the second cleaning mode. Therefore, the first rolling brush body 31 and the second rolling brush body 32 can be interchangeably installed in the rolling brush cavity to enable the floor brush 100 to be in the first cleaning mode or the second cleaning mode, so that the floor brush 100 can clean different working surfaces.

Meanwhile, the rolling brush body 3 can rotate in the rolling brush cavity, so that the working surface can be cleaned, and the dust collection function of the dust collector is realized. In the floor brush 100 according to the embodiment of the present invention, the first rolling brush body 31 and the second rolling brush body 32 are interchangeable, and when a user needs to clean different working surfaces, the user can select the first cleaning mode or the second cleaning mode according to the actual environment of the working surface to be cleaned, and further select different rolling brush bodies 3, so that the dust collection function of the dust collector can be improved, the use range of the dust collector is expanded, and the use of the floor brush 100 is more flexible.

According to the floor brush 100 for the dust collector of the embodiment of the invention, by arranging the rolling brush body 3, the rolling brush body 3 at least comprises the first rolling brush body 31 and the second rolling brush body 32 which can be exchanged, the first rolling brush body 31 is suitable for working in the first cleaning mode, and the second rolling brush body 32 is suitable for working in the second cleaning mode, so that the dust collecting function of the dust collector can be improved, the use range of the dust collector is expanded, and the use of the floor brush 100 is more flexible.

As shown in fig. 13 to 17, according to some embodiments of the present invention, the cleaning elements provided on the surface of the first brush body 31 are formed as bristle members, and the cleaning elements provided on the surface of the second brush body 32 are formed as fur members. As is known, bristles are generally referred to as hard, long hairs on horses or pigs, while pile hairs are referred to as soft, fine hairs. It can thus be seen that the first rolling brush body 31 is adapted to cleaning a carpet, i.e., the first cleaning mode can be used for cleaning a carpet, and the second rolling brush body 32 is adapted to cleaning a floor, i.e., the second cleaning mode can be used for cleaning a floor. So that the user can select a cleaning mode of the floor brush according to the environment of the work surface to be cleaned, thereby selecting the first drum brush body 31 or the second drum brush body 32, while being advantageous to secure the cleaning ability of the floor brush 100.

As shown in fig. 1, according to some embodiments of the present invention, the floor brush 100 further includes an upper cover assembly 2, and the upper cover assembly 2 is detachably disposed on the floor brush base 1 and connected to the roller brush body 3. Therefore, when the upper cover assembly 2 is matched and connected with the floor brush base 1, the dust collector can work normally. When a user needs to clean or replace the rolling brush body 3, the upper cover assembly 2 can be disengaged from the floor brush base 1 (i.e. detached from the floor brush base 1), and the rolling brush body 3 can be cleaned or replaced. The structure is arranged, so that the operation of cleaning or replacing the rolling brush body 3 by a user is convenient, time and labor are saved, and the use feeling of the user can be improved. In addition, it can be understood that, since the upper cover assembly 2 is detachably connected to the floor brush base 1, a user can replace the upper cover assembly 2 engaged with the roller body 3 at the same time when replacing the roller body 3. So, the user need not to dismantle the rolling brush body 3 from with it complex upper cover subassembly 2, and then can improve the efficiency of changing the rolling brush body 3, improves user's use and experiences.

As shown in fig. 13 to 14, according to some embodiments of the present invention, the upper cover assembly 2 includes a first upper cover 2a and a second upper cover 2b, the first upper cover 2a is coupled to the first rolling brush body 31, the second upper cover 2b is coupled to the second rolling brush body 32, and the first rolling brush body 31 and the first upper cover 2a and the second rolling brush body 32 and the second upper cover 2b are interchangeably mounted to the floor brush base 1 to clean different working surfaces. Therefore, when the user replaces the rolling brush body 3, the upper cover assembly 2 correspondingly matched with the rolling brush body 3 can be replaced at the same time. So, the user need not to dismantle the rolling brush body 3 from the upper cover subassembly 2 that corresponds the complex with it, and then can improve the efficiency of changing the rolling brush body 3, improves user's use and experiences.

It will also be understood that the cleaning elements provided on the surface of the roller brush body 3 may be formed as pile members (for cleaning the floor), as shown in fig. 9 and 11, or as bristle members (for cleaning the carpet), as shown in fig. 8 and 10. When a user uses the vacuum cleaner to clean different working surfaces (carpets or floors), different cleaning modes of the floor brush 100 can be selected according to the environment of the working surface to be cleaned, and then different types of rolling brush bodies 3 can be selected. As shown in fig. 8 and 10, when the user selects the rolling brush body 3 whose surface is provided with the cleaning element as the bristle member to clean the carpet, the friction between the rolling brush body 3 and the carpet is large, and at the same time, the small dust on the carpet is more and is scraped by the rolling brush body 3, so that the area of the bottom opening of the rolling brush cavity is relatively small, which is beneficial to increasing the negative pressure in the rolling brush cavity, increasing the suction force of the dust collector, and sucking more dust into the dust collector, thereby enhancing the cleaning effect of the dust collector. As shown in fig. 9 and 11, when the user selects the rolling brush body 3 whose cleaning element is a fluff piece to clean the floor, the dust particles on the floor are large, so that the dust collector can suck large dust particles into the interior, the opening area of the bottom of the rolling brush cavity should be relatively large, and the cleaning effect of the dust collector can be enhanced. It will be appreciated that the variation in the size of the area of the bottom opening of the roller brush chamber may be achieved by selecting different sizes of the upper cover assembly 2. That is, the rolling brush bodies 3 with different cleaning elements arranged on the surface can have different sizes of the upper cover assembly 2 correspondingly matched with the rolling brush bodies, thereby improving the cleaning capability of the floor brush 100 and the dust collection function of the dust collector.

According to some embodiments of the present invention, one end of the upper cover assembly 2 is pivotally connected to the floor brush base 1, and the other end of the upper cover assembly 2 is detachably connected to the floor brush base 1. Therefore, when the other end of the upper cover component 2 is matched and connected with the floor brush base 1, the dust collector can work normally. When the other end of the upper cover assembly 2 is disengaged from the floor brush base 1 (i.e., detached from the floor brush base 1), the upper cover assembly 2 can rotate relative to the floor brush base 1 around the end of the upper cover assembly 2 pivotally connected to the floor brush base 1, i.e., the upper cover assembly 2 can rotate relative to the floor brush base 1. Meanwhile, when the user needs to clean or replace the rolling brush body 3, the user only needs to make the other end of the upper cover assembly 2 disengaged from the floor brush base 1 and then rotate the upper cover assembly 2 to a position convenient for the user to operate, so that the rolling brush body 3 can be cleaned or replaced. The structure is arranged, so that the operation of cleaning or replacing the rolling brush body 3 by a user is convenient, time and labor are saved, and the use feeling of the user can be improved.

As shown in fig. 1, 3-8, and 10-11, in some embodiments of the present invention, the upper cover assembly 2 includes: a cover 21, a first end cap 22 and a second end cap 23. Specifically, the first end cap 22 is disposed at one end of the cover body 21 and connected to the cover body 21, and the first end cap 22 is pivotally connected to the floor brush base 1. The second end cover 23 is arranged at the other end of the cover body 21 and connected with the cover body 21, and the second end cover 23 is detachably connected with the floor brush base 1. Therefore, the upper cover assembly 2 is pivotally connected with the floor brush base 1 through the first end cover 22, and the upper cover assembly 2 is detachably connected with the floor brush base 1 through the second end cover 23.

Specifically, the cover body 21 is detachably connected to the first end cap 22 and the second end cap 23, respectively, and the roll brush body 3 is detachably connected to the cover body 21 and the second end cap 23, respectively. It can be seen that the cover 21 can be detached separately, the second cap 23 can be detached separately, and the cover 21 and the second cap 23 can be detached together. The rolling brush body 3 can be detached together with the cover body 21, the rolling brush body 3 can also be detached together with the second end cap 23, the rolling brush body 3 can also be detached together with the cover body 21 and the second end cap 23 at the same time, and the rolling brush body 3 can also be detached separately after at least one of the cover body 21 and the second end cap 23 is detached. Thereby the mode of making clean and change the round brush body 3 is diversified, and the user can take off the round brush body 3 through multiple mode, and the user of being convenient for cleans or changes the round brush body 3.

For example, as shown in fig. 4 to 5, the cover body 21 is detachably connected to the first end cap 22, and the roll brush body 3 is detachably connected to the cover body 21. Therefore, when the second end cap 23 is disengaged from the floor brush base 1 and then the cover body 21 is disengaged from the first end cap 22, the whole body formed by the cover body 21 and the second end cap 23 can be detached from the floor brush base 1. Since the roller brush body 3 is detachably coupled to the cover body 21, the roller brush body 3 can be detached simultaneously with the cover body 21 if the roller brush body 3 is coupled to the cover body 21. If the roller brush body 3 is disengaged from the cover body 21, the user can first detach the cover body 21 and the second end cap 23 from the floor brush base 1, and then remove the roller brush body 3. Thereby be convenient for the user more and clean or change the round brush body 3, promote user's use experience.

At this time, there are two ways for the user to clean or replace the roller brush body 3, the first being: as shown in fig. 5, the cover 21, the second end cap 23 and the roller brush body 3 are removed from the floor brush base 1. The second method is as follows: as shown in fig. 4, the cover 21 and the second end cap 23 are removed from the base 1, and then the roller brush body 3 is removed.

At this time, the second end cap 23 may be fixedly connected to the cover body 21 by screws. So that the reliability of the upper cap assembly 2 can be improved.

For another example, as shown in fig. 6, the cover body 21 is detachably connected to the second end cap 23, and the roll brush body 3 is detachably connected to the second end cap 23. Therefore, when the second end cap 23 is disengaged from the floor brush base 1 and then the cover body 21 is disengaged from the second end cap 23, the second end cap 23 can be removed as a whole. Since the roll brush body 3 is detachably coupled to the second end cap 23, if the roll brush body 3 is coupled to the second end cap 23, the roll brush body 3 and the second end cap 23 can be simultaneously detached. If the rolling brush body 3 is disengaged from the second end cap 23, the user can first remove the second end cap 23 and then remove the rolling brush body 3. Thereby be convenient for the user more and clean or change the round brush body 3, promote user's use experience.

At this time, there are two ways for the user to clean or replace the roller brush body 3, the first being: as shown in fig. 6, the second end cap 23 is removed together with the roller brush body 3. The second method is as follows: the second end cap 23 is removed first and then the brush body 3 is removed. Therefore, in the floor brush 100 according to the embodiment of the present invention, the manner of taking the rolling brush body 3 is flexible, and the user can select the manner of taking the rolling brush body 3 according to actual requirements.

Specifically, the roll brush body 3 is axially separable from the cover body 21. Accordingly, when the user detaches the roller brush body 3 from the upper cover assembly 2, the user can move the roller brush body 3 in the axial direction of the roller brush body 3 and separate the roller brush body 3 from the cover body 21.

As shown in fig. 1 and 2, according to some embodiments of the present invention, the floor brush 100 further includes a connecting assembly 5, the connecting assembly 5 is disposed on the floor brush base 1, and the upper cover assembly 2 is pivotally connected to the connecting assembly 5. Therefore, the upper cover assembly 2 is pivotally connected with the floor brush base 1 through the connecting assembly 5, and the rotating function of the upper cover assembly 2 relative to the floor brush base 1 can be realized. The reliability of the floor brush 100 is ensured.

In some embodiments of the invention, the connecting member 5 is a hinge. Therefore, the connecting assembly 5 has a simple structure, low cost and wide source, and is beneficial to ensuring the reliability of the pivotal connection between one end of the upper cover assembly 2 and the floor brush base 1, and further ensuring the reliability of the floor brush 100. In particular, the hinge may be fixed to the floor brush base 1 by means of screws.
