[0002] With the improvement of living standards, more and more people are choosing to use vacuum cleaners to clean their homes. Vacuum cleaners are typically used to pick up and clean dust, hair, particles, and other debris from floors. To improve cleaning ability, existing vacuum cleaners have roller brush assemblies on their floor brushes. A motor drives the roller brush assembly to rotate, sending debris from the floor into the suction inlet, where negative pressure suction removes the debris. However, due to limitations in the installation structure of the roller brush assembly, existing floor brushes often fail to achieve thorough cleaning along the edges, resulting in incomplete cleaning and reduced cleaning power and effectiveness.

[0024] To further illustrate the technical means and effects adopted by this application to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0025] like Figures 1-8 As shown, this utility model discloses a floor brush for side cleaning, including a base 1, a roller brush assembly 2 rotatably mounted on the base 1, and a cover 3 detachably connected to the base 1; a drive device 14 is integrated in the base 1, and the drive device 14 drives the roller brush assembly 2 to rotate.

[0026] When cleaning with a floor brush, the roller brush assembly 2 comes into contact with the ground, and as the roller brush assembly 2 rotates, it carries the debris on the ground into the suction port 11 at the bottom of the base 1. The suction port 11 is usually equipped with negative pressure suction, which quickly sucks away the debris that enters the suction port 11, thereby achieving fast and efficient cleaning.

[0027] In order to improve the cleaning ability of the roller brush assembly 2, this utility model provides side cleaning mechanisms on both ends of the roller brush assembly 2. The side cleaning mechanisms provide side cleaning for the floor brush located on both ends of the roller brush assembly 2, thereby eliminating the blind spots that cannot be cleaned between the end of the floor brush and the wall when the floor brush is used alone by the roller brush assembly 2, which is conducive to improving the cleaning ability of the floor brush.

[0028] A roller brush groove is provided at the front end of the base 1, and the roller brush assembly 2 is rotatably assembled in the roller brush groove. The suction port 11 at the bottom of the base 1 is located at the rear end of the base relative to the roller brush groove. The drive device 14 is coupled to one end of the roller brush assembly 2, thereby driving the roller brush assembly 2 to rotate in the roller brush groove and carrying the garbage on the ground into the suction port 11.

[0029] The side cleaning mechanism includes: a first movable cavity 131 located at both ends of the roller brush groove on the base 1, and a side brush assembly 17 disposed within the first movable cavity 131. For example... Figure 5As shown, the side brush assembly 17 includes a side brush body 171 and multiple bundles of soft bristles 174 disposed on the side brush body 171. The side brush assembly 17 is confined within the first movable cavity 131, and the lower end of the soft bristles 174 extends out of the side of the base 1 by at least 1 mm (see...). Figure 2 and Figure 7 (As shown).

[0030] By installing side brush assemblies 17 on both ends of the floor brush, and setting soft bristles 174 extending from the side of the base 1, the soft bristles 174 can clean the blind spots on both sides of the floor brush that cannot be cleaned by the roller brush assembly 2 when cleaning with the floor brush. Therefore, the side brush assembly 17 and the roller brush assembly 2 work together to improve the shortcomings of existing floor brushes in terms of thorough cleaning, thus enhancing the cleaning ability and effect of the floor brush.

[0031] The side cleaning mechanism also includes: a second movable cavity 132 provided on both ends of the roller brush groove on the base 1, the second movable cavity 132 being located between the first movable cavity 131 and the end of the roller brush groove; a rolling assembly 18 rotatably disposed in the second movable cavity 132, the rolling assembly 18 including a rotating shaft 181 and a roller 182 coaxially fixed on the rotating shaft 181 and a top platform 183 (the top platform 183 usually adopts a non-circular shape structure) that can drive the side brush body 171 to move up and down reciprocally. The roller 182 is located in the second movable cavity 132, and the top platform 183 abuts against the bottom side of the side brush body 171 so that when the roller 182 rotates, the side brush assembly 171 moves up and down reciprocally through the top platform 183, thereby improving the cleaning ability of the side brush assembly 17.

[0032] One end of the rotating shaft 181 is connected to the base 1 via a bearing 19, so that the roller 182 is rotatably assembled in the second movable cavity 132.

[0033] When the floor brush is in use, both the roller brush assembly 2 and the roller 182 are in contact with the ground. When the floor brush is moved, the roller 182 rotates in the second movable cavity 132, and drives the top platform 183 to rotate synchronously through the rotating shaft 181. Since the top platform 183 is not circular, the height of the side brush body 171 relative to the ground is different when the top platform 183 contacts the bottom side of the side brush body 171 at different positions during the rotation. This causes the side brush assembly 17 to move up and down repeatedly. During the up and down movement, the lower end of the soft brush 174 is used to clean the ground on both sides of the floor brush.

[0034] The roller 182 typically employs a multi-tooth structure to increase friction and improve torque, and preferably uses an outer soft rubber coating to reduce noise during rolling. The top platform 183 is preferably a prism with an equilateral polygonal cross-section, and the polygon has rounded corners to prevent it from jamming during operation with the side brush assembly 17.

[0035] When any side of the top platform 183 comes into contact with the side brush body 171, the side brush body 171 is in a lower position close to the ground; as the top platform 183 rotates with the roller 182, when the junction of two adjacent sides of the top platform 183 comes into contact with the side brush body 171, the side brush body 171 is in a higher position close to the ground.

[0036] In addition, through repeated experiments, it was found that when the soft brush 174 on the side brush assembly 17 moves up and down a distance of 2-3mm during use by the rolling component 18, the side brush assembly 17 can achieve better cleaning results in the most likely cleaning environments such as homes and offices.

[0037] When the top platform 183 is implemented using an equilateral polygonal prism, if the side brush assembly 17 is to move vertically by 2-3 mm, the top platform 183 needs to be designed to be larger, which is not conducive to the design requirements of miniaturizing the floor brush. Therefore, the side of the bottom surface of the side brush body 171 near the top platform 183 is set as a wavy abutment surface 172, and the top platform 183 abuts against the abutment surface 172; the side of the bottom surface of the side brush body 171 away from the top platform 183 is set as a bristle-forming surface 173, and multiple bundles of soft bristles 174 are fixed on the bristle-forming surface 173.

[0038] In addition, the bristle-planting surface 173 is set as an inclined surface, so that when the upper end of the soft bristle brush 174 is fixed on the bristle-planting surface 173, the soft bristle brush 174 is set at an angle so that the lower end of the soft bristle brush 174 is tilted downward and extends out of the side of the base 1 by at least 1 mm.

[0039] Furthermore, in order to ensure that the side brush assembly 17 maintains reliable up-and-down reciprocating movement under the action of the rolling assembly 18, a fixing frame 15 is provided at the upper end of the first active cavity 131, and a return spring 16 is provided between the fixing frame 15 and the top surface of the side brush body 171.

[0040] For example, the two opposite side walls of the fixing frame 15 are respectively provided with fastening positions 151, which are fastened and connected to the top ends of the two opposite cavity walls 1311 of the first movable cavity 131 through the fastening positions 151, thereby quickly installing the fixing frame 15 on the upper end of the first movable cavity 131, such as Figure 6 As shown.

[0041] The number of return springs 16 is one or more. Usually, there are two return springs 16, which are located at opposite ends of the side brush body 171. The two return springs 16 generate a reliable downward return force on the side brush body 171.

[0042] Recombined Figure 2 and Figure 8As shown, a soft bristle strip 12 is provided at the bottom of the base 1 behind the suction port 11, with the two ends of the soft bristle strip 12 positioned close to the soft bristle brushes 174 at both ends of the floor brush. When the floor brush is placed on the ground for use, the roller brush assembly 2, the roller 182, and the soft bristle strip 12 all abut against the ground, thereby forming a relatively sealed suction area between the roller brush assembly 2, the soft bristle brushes 174, and the soft bristle strip 12 on the bottom side of the base 1, and the suction port 11 is located within this suction area.

[0043] The floor brush is connected to the device head (not shown) via the air duct 5 to form a cleaning device. When in use, the cleaning device uses the air duct 5 to create a negative pressure suction at the suction port 11, thus creating a negative pressure zone in the suction area at the bottom of the floor brush, making it easier for debris in the suction area to be sucked in from the suction port 11 under the action of negative pressure suction.

[0044] The cleaning mechanism of the floor brush is as follows: The drive device 14 drives the roller brush assembly 2 to rotate counterclockwise at high speed at the front end of the floor brush, bringing the objects to be cleaned into the suction area of ​​the floor brush; at the same time, during the back and forth movement of the floor brush, the roller 182 rotates due to friction with the ground, and the roller 182 drives the regular polygonal top platform 183 to rotate. Each highest point lifts the side brush body 171 as the roller 183 rotates, thereby raising the soft bristles 174 on the side brush assembly 17 by 2-3mm. During the process of the side brush soft bristles being raised, dust and small particles can enter the suction area of ​​the floor brush. The objects to be cleaned are sucked in from the suction port 11 under negative pressure, thereby achieving a better cleaning effect.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
