Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, specifically to a floor brush structure for cleaning equipment, applicable to various floor cleaning equipment such as vacuum cleaners, floor scrubbers, and sweeping robots. Background Technology

[0002] The existing floor brush structure of cleaning equipment has many shortcomings: First, the suction port design is simple, mostly a single suction port on one side or a single suction port at the bottom. During cleaning, it can only pick up dirt in one direction of movement, resulting in a gap in the suction during the back-and-forth cleaning process, leading to low cleaning efficiency. Second, the side arms of the floor brush are mostly fixed structures, which cannot be adjusted according to the cleaning scenario. It is difficult to clean narrow areas such as under sofas, corners, and furniture gaps, resulting in cleaning dead spots. Third, some floor brushes lack auxiliary moving parts, resulting in greater resistance and poor mobility when manually operated. Fourth, when cleaning in the dark, due to insufficient light, it is difficult for users to observe the distribution of dirt and the cleaning effect, which can easily lead to missed cleaning problems. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a floor brush with a variable angle suction inlet.

[0004] The technical solution adopted by this invention to solve its technical problem is: A floor brush with a variable-angle suction inlet includes a brush body and a pair of symmetrically arranged rocker arms. The brush body has a suction channel. Each rocker arm includes a base, a connecting channel on the base, and an arm shell fixed to the base and capable of covering the connecting channel. The bottom surface of the base has an integrally formed bidirectional suction port, which communicates with one end of the connecting channel. Integral-formed stop block assemblies are located on the front and rear sides of the bottom of the base. The brush body and rocker arms are also connected by a connector, which includes a connecting base shell, a protective shell that can be fitted onto the connecting base shell, and a connecting element disposed between the connecting base shell and the protective shell. The air duct between the shells has a hinge interface on the bottom shell for inserting the upper end of the connecting channel. The upper end of the air duct is connected to the air intake channel. The rocker arm is symmetrically arranged below the floor brush body through a connector. The connecting channel inside the rocker arm is inserted into the hinge interface to form a rotatable connection. The lower end of the air duct is connected to one end of each of the two connecting channels. A limiting member is fixed at one end of the connecting channel inserted into the hinge interface. The limiting member has at least one round hole with a ball bearing inside. A transmission ring located inside the connector is sleeved on the limiting member. A cylinder is provided at the end of the bottom shell away from the hinge interface. A return spring that undergoes elastic deformation is connected between the cylinder and the transmission ring.

[0005] Furthermore, the bottom of the rocker arm is provided with at least two casters, which are symmetrically distributed at both ends of the bidirectional suction port.

[0006] Furthermore, the block assembly includes several protrusions, which are arranged in two parallel groups, with the protrusions in each group being equidistant.

[0007] Furthermore, the stop assembly includes a pair of parallel protrusions.

[0008] Furthermore, a light is embedded in the front of the floor brush body.

[0009] Compared with the prior art, the present invention has the following advantages and effects: 1. The two-way suction port design eliminates the suction gap during cleaning, and can achieve efficient dust suction by moving forward and backward, thus improving cleaning efficiency.

[0010] 2. The rocker arm is rotatable, and the suction inlet can be adjusted in angle, which not only expands the cleaning range, but also folds up to reach into narrow gaps, thoroughly solving the problem of cleaning dead corners and expanding the application range of this floor brush; 3. It is equipped with a return spring and ball bearings, which can improve the smoothness of the rocker arm rotation and ensure that the rocker arm does not rotate excessively back and forth.

Detailed Implementation

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Example 1.

[0021] like Figures 1-6 As shown, this embodiment includes a floor brush body 1, a pair of symmetrically arranged rocker arms 2, and a connector 3 that connects the floor brush body 1 and the rocker arms 2 together. The floor brush body 1 is provided with a suction channel 11, and the end of the suction channel 11 is usually connected to a fan to provide suction for the floor brush.

[0022] like Figures 1-6 As shown, the rocker arm 2 includes a chassis 21, a connecting channel 22 disposed on the chassis 21, and an arm housing 25. The bottom surface of the chassis 21 has an integrally formed bidirectional suction port 23, which communicates with one end of the connecting channel 22. The bottom of the rocker arm 2 has two casters 24, symmetrically distributed at both ends of the bidirectional suction port 23, allowing the rocker arm 2 to move freely forward, backward, left, and right. The arm housing 25 is fixed to the chassis 21 and, in conjunction with the chassis 21, covers the connecting channel 22 to prevent dust from entering the shaft connection and affecting performance. The bottom sides of the chassis 21 have integrally formed stop block assemblies 26, each consisting of several protrusions arranged in two parallel groups. The protrusions in each group are equidistant, with gaps between them for passage. When the floor brush is used, the protrusions function as the bristles in a conventional floor brush.

[0023] like Figures 1-6 As shown, the connector 3 includes a connecting base shell 31, a protective outer shell 32 that can be covered by the connecting base shell 31, and an air duct 33 disposed between the connecting base shell 31 and the protective outer shell 32. The connecting base shell 31 has a hinge interface for inserting the upper end of the connecting channel 22. The upper end of the air duct 33 is connected to the suction channel 11. Specifically, the rocker arm 2 is symmetrically disposed below the floor brush body 1 through the connector 3. The connecting channel 22 inside the rocker arm 2 is inserted into the hinge interface to form a rotatable connection. The lower end of the air duct 33 is connected to one end of each of the two connecting channels 22. When the fan connected to the tail end of the suction channel 11 is started, objects outside the floor brush will sequentially enter the suction channel 11 through the bidirectional suction port 23, the connecting channel 22, and the air duct 33.

[0024] like Figures 1-6As shown, a limiting member 29 is fixed at one end of the connecting channel 22 inserted into the hinge interface. The limiting member 29 is used to prevent the rocker arm 2 from dislodging from the connecting member 3. The limiting member 29 has at least one circular hole, and a ball bearing 27 is provided in the circular hole. The ball bearing 27 abuts between the connecting bottom shell 31 and the protective outer shell 32. When the rocker arm 2 rotates, the ball bearing 27 is used to limit the path of the rotation process and improve the smoothness of the rotation. A transmission ring 28 located inside the connecting member 3 is sleeved on the limiting member 29. A cylinder 34 is provided at the end of the connecting bottom shell 31 away from the hinge interface. A return spring 35 that undergoes elastic deformation is connected between the cylinder 34 and the transmission ring 28. The return spring 35 will undergo elastic deformation when the rocker arm 2 rotates, which can prevent the rocker arm 2 from rotating excessively, and at the same time help the rocker arm 2 to complete the return when no force is applied.

[0025] like Figures 1-6 As shown, a light 4 is embedded in the front of the brush body 1. The light 4 can provide sufficient lighting, and the distribution of debris can be clearly observed when cleaning in the dark, so as to avoid missing any cleaning spots.

[0026] Example 2.

[0027] like Figure 7 As shown, the baffle assembly 26 in this embodiment consists of a pair of parallel protrusions. A gap is provided between the protrusions on the same side of the two rocker arms 2, which allows dirt to pass through and be sucked in.

[0028] The above description is merely illustrative of the invention. Those skilled in the art can make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined by the claims, all of which should fall within the protection scope of this invention.
