Description

The present invention relates to ground cleaning techniques, especially to ground brush assemblies.

Floor brushes are commonly used for floor cleaning. For example, after connecting to a hand cleaner via an extension tube, the user can power the floor brush assembly through the hand cleaner to rotate the roller brush to clean the floor.

In the commercially available double roller brush structure and the floor brush assembly described in Patent Document 1, an air inlet channel is formed between the two roller brushes, and the rotation direction of the two roller brushes is toward the air inlet channel. This is relatively costly because the two motors drive the two roller brushes separately to achieve forward and reverse rotation. Using one motor makes the drive mechanism connected to the output end very complicated, costly, and makes the overall volume of the ground brush relatively large, making it inconvenient to operate.

The following is a clear and complete description of the technical solutions in the embodiments of the present invention, along with the drawings in the embodiments of the present invention. Of course, the embodiments described are only a part of the embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the art without creative work shall be included in the scope of protection of the present invention.

The floor brush assembly 1 shown in FIG. 1 or 2 is provided with a base 2, a roller brush assembly 3, a roller brush drive mechanism 4, a cover plate 5, and a floor brush joint 6 connected in this order.

The roller brush assembly 3 includes a roller brush end cover 31, a first roller brush 32 and a second roller brush 33.

The roller brush end cover 31 is fixed to the base 2. The roller brush end cover 31 is provided on a connecting shaft (not shown).

The first roller brush 32 and the second roller brush 33 are connected to the roller brush end cover 31 via a connecting shaft. For convenient placement of the air duct, the first roller brush 32 and the second roller brush 33 are arranged horizontally in the front-rear direction, and the base 2 is arranged between the first roller brush 32 and the second roller brush 33 for dust. The suction port 21 is used.

The dust suction port 21 is connected to an external vacuum unit (shown in the figure). The external vacuum unit is a vacuum generator such as a motor or fan. In this embodiment, the first roller brush 32 and the second roller brush 33 are attached to the first roller brush cover 22 and the second roller brush cover 23 in order to prevent dust from being scattered when the roller brush is rotated. It is a base formed so as to correspond to each other.

The cover plate 5 is located between the first roller brush cover 22 and the second roller brush cover 23, surrounds the roller brush end cover 31 and the base 2 to form a cavity, and is installed at the upper end of the roller brush end cover 31. An opening 51 corresponding to the cover button 34 is provided and is connected to the roller brush end cover 31 via the cover button 34 and the roller brush end cover 31.

The cover plate 5 also has an opening 51 corresponding to the dust suction port 21. The dust suction port 21 and the opening 51 are connected via a seal ring. Connection positions 53 are symmetrically provided at both ends of the opening 51.

A rotating shaft hole 54 is provided inside the connection position 53. By providing rotating shafts 61 corresponding to the rotating shaft holes 54 on both sides of the floor brush joint 6, the floor brush joint 6 can rotate back and forth with respect to the cover plate 5. One end of the floor brush joint 6 has an opening 51, and the other end has an outlet 62 for connecting to the main body of the hand cleaner or an extension pipe.

The roller brush drive mechanism 4 is arranged on the side away from the roller brush end cover 31. The roller brush drive mechanism 4 includes a roller brush motor 41, a drive gear 42, a driven gear 43, a first drive wheel 44, and a second drive wheel 45.

The drive gear 42 is located on the output shaft of the roller brush motor 41, and drives the first drive wheel 44 by rotating the belt. The first drive wheel 44 is connected to the first roller brush 32 to rotate the first roller brush 32. The driven gear 43 is driven by the drive gear 42, the second drive wheel 45 is driven by the rotation of the belt, and the second drive wheel 45 is rotated to rotate the second roller brush 33. As a result, the second roller brush 33 and the first roller brush 32 rotate in opposite directions.

Preferably, in order to rotate the first roller brush 32 and the second roller brush 33 synchronously, the number of teeth of the drive gear 42 and the driven gear 43 is the same, and the first drive wheel 44 and the second drive wheel 45 have the same number of teeth. The diameter is the same. In order to make the structure more compact, the drive gear 42 and the driven gear 43 are arranged vertically. If size is not taken into consideration, it can be arranged on the left and right so that they can be engaged and do not interfere with each other. In order to improve the appearance, the drive end cover 46 is provided on the outside of the roller brush drive mechanism 4, and the shape of the drive end cover 46 corresponds to the roller brush end cover 31.

The usage of the present invention will be described below.
As shown in FIG. 3, the floor brush assembly 1 is connected to the hand cleaner 8 via an extension tube 7. After turning on the power of the hand cleaner 8, three become conductive connections. The internal power supply unit of the hand cleaner 8 supplies electric power to the roller brush motor 41. The drive gear 42 rotates to rotate the driven gear 43 in the opposite direction.

The first roller brush 32 and the second roller brush 33 rotate toward the dust suction port 21, and the two rotation speeds are synchronized. The first roller brush 32 and the second roller brush 33 are useful for increasing the degree of vacuum of the dust suction port 21 and increasing the suction force by sealing the surface to be cleaned. As the floor brush moves back and forth, the two roller brushes always carry dust to the dust suction port 21. Compared to a single roller brush, dust is less likely to remain on the work surface and the cleaning effect is excellent.

Although embodiments of the present invention have been shown and described, various changes, modifications, and modifications to these embodiments have been made to ordinary engineers in the art without departing from the principles and spirit of the present invention. It may be recognized that substitutions and transformations can be made. The scope of this utility model right is defined by the scope of claims for utility model registration and their equivalents.
