Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a cleaning brush with the function of breaking down stubborn stains. Background Technology

[0002] Existing floor cleaning brushes typically rely on a single rotating roller brush for cleaning. They are often unable to effectively remove and peel off stubborn, dried stains such as dried mud and sugar stains. Users often need to stop the machine midway and manually wipe or scrape them repeatedly, which greatly reduces cleaning efficiency and user experience.

[0003] Some products on the market have attempted to incorporate vibrating brush structures, but most use ordinary eccentric motors for drive. These motors have low vibration frequencies and limited amplitudes, making it difficult to break down stubborn solid dirt in a short time. Furthermore, the lack of a reasonable coordinated layout and power distribution between these vibrating brushes and the main roller brush results in poor overall cleaning performance, failing to achieve both deep cleaning and large-area cleaning. In addition, the internal transmission structure of floor brushes often uses enclosed gearboxes or ordinary belts, which are not only complex and costly, but also prone to slippage, jamming, or even damage in damp conditions or when small dirt particles intrude. Daily disassembly and cleaning of the roller brush is also very inconvenient.

[0004] Therefore, there is an urgent need for a floor cleaning brush that can efficiently break down stubborn stains, has a reliable structure, and is easy to maintain. Summary of the Invention

[0005] The purpose of this invention is to provide a cleaning brush with the function of breaking down stubborn stains, so as to solve the problems of existing cleaning brushes having weak ability to remove stubborn stains, low cleaning efficiency, complex structure, and inconvenient maintenance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cleaning floor brush with the function of breaking down stubborn stains, comprising: a main housing and a secondary housing, wherein the secondary housing is mounted on the front side of the main housing;

[0007] A sweeping and vibration assembly is disposed inside the sub-housing housing. The sweeping and vibration assembly includes a sweeping frequency motor and a brush that is driven by the sweeping frequency motor and extends out of the bottom of the sub-housing housing. The sweeping frequency motor is used to drive the brush to perform high-frequency reciprocating oscillation to break down stubborn solid dirt through high-frequency impact.

[0008] The main motor is installed inside the main housing, and the output end of the main motor is connected to the central gear of a helical gear set.

[0009] A connecting base is fixed inside the main housing, and the helical gear is assembled on the connecting base;

[0010] The transmission component has its input end connected to the output end of the helical gear set.

[0011] The spline base is connected to the output end of the transmission assembly; and the roller brush is detachably connected to the spline base and driven to rotate by the main motor via the helical gear set, the transmission assembly, and the spline base, for cleaning up the broken-down dirt.

[0012] The brush is located in front of the roller brush and has a narrow strip structure.

[0013] As a further description of the above technical solution:

[0014] The sweeping and vibration assembly also includes an inner tube, which is fixed to the inner circumferential surface of the brush, and the output shaft of the sweeping frequency motor is tightly inserted and fixed in the inner tube.

[0015] As a further description of the above technical solution:

[0016] The sweep frequency motor drives the brush to reciprocate and swing at an angle of 50-70°, and its vibration frequency can reach up to 60,000 times / minute.

[0017] As a further description of the above technical solution:

[0018] The transmission assembly includes a transmission gear, a chain, and a sprocket. The transmission gear is coaxially disposed on the right outer wall of the helical gear set. The chain is meshed and sleeved between the transmission gear and the sprocket. A spline seat is integrally disposed or fixedly connected to the left side of the sprocket.

[0019] As a further description of the above technical solution:

[0020] A bearing for radial support is provided on the right side of the transmission gear.

[0021] As a further description of the above technical solution:

[0022] The transmission assembly is covered by an outer shell to isolate it from dirt.

[0023] As a further description of the above technical solution:

[0024] The sub-shell and the main shell are connected by a detachable snap-fit, and the brush is detachably installed below the sub-shell.

[0025] As a further description of the above technical solution:

[0026] The end of the roller brush is provided with a spline hole, and the center of the spline seat is provided with a spline shaft. The roller brush achieves torque transmission and detachable connection through the cooperation of the spline shaft and the spline hole.

[0027] As a further description of the above technical solution:

[0028] The main housing is also equipped with a control circuit board, which is electrically connected to the main motor and the sweep frequency motor respectively, and is used to independently control the start and stop and speed / frequency of the two.

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0030] 1. In this invention, through the coordinated work of the front high-frequency sweeping brush and the rear rotating roller brush, the sweeping motor first drives the brush to perform high-frequency reciprocating impacts of up to 60,000 times / minute, which quickly loosens and breaks down stubborn solid dirt, and then the roller brush directly rolls it into the suction port, which greatly improves the thoroughness and efficiency of cleaning.

[0031] 2. In this invention, the sweeping and vibration assembly adopts a compact inner tube direct drive structure with a sweeping and vibration angle of 50-70°, specifically designed to break down dry and hardened stains. The narrow strip brush provides precise action and significant results. The transmission assembly uses a combination of helical gears and a chain, resulting in a stable and reliable structure. Combined with the outer casing, it effectively isolates dirt, making the entire machine highly adaptable.

[0032] 3. In this invention, the secondary housing and the main housing are snap-fitted together, and the brush can be disassembled separately; the roller brush can be quickly disassembled without tools via a splined base, facilitating daily cleaning and maintenance for users. The main motor and the sweep frequency motor can be independently adjusted via a control circuit board, allowing for free switching according to the scenario while effectively saving energy and reducing noise.
