This application claims priority to Chinese Patent Application No. 202420001346.2, filed on Jan. 2, 2024, which is hereby incorporated by reference in its entirety.
The present disclosure relates to the technical field of cleaning brushes, and particularly to an electric cleaning brush.
An electric cleaning brush usually includes a motor and a brush broom, and the motor drives the brush broom to rotate. In the prior art, a motor shaft and a brush broom are coaxially arranged, and a motor is always located behind the brush broom when in use. When being started, the motor drives the brush broom to rotate; when the brush broom comes into contact with a cleaning surface, it is difficult for a user to control the direction of the brush broom due to its rotation, and the user usually needs to press the brush broom hard, otherwise, the brush broom will pull to one side. Moreover, in the cleaning process, the brush broom will be subjected to significant vibration, making it inconvenient to use and resulting in low cleaning efficiency and poor cleanliness.
An objective of the present disclosure is to provide an electric cleaning brush, aiming to improving the existing design of electric cleaning brushes, and solving the problems in the prior art that the motor shaft and the brush broom are coaxially arranged, and the direction of the brush broom during cleaning is hard to be controlled, resulting in substantial vibrations of the brush broom, inconvenient use and low cleaning efficiency.
The present disclosure is implemented through the following technical solution: an electric cleaning brush includes a handle and a brush broom assembly, where the brush broom assembly includes a frame, a motor and a rolling brush, the rolling brush includes a roller, the handle is connected to the frame, the motor is installed on the frame, a fixed shaft is arranged on the frame, the motor is provided with an output rotating shaft, and the output rotating shaft and the fixed shaft are arranged on a common central axis; a first coupling groove and a second coupling groove are separately formed on two ends of the roller, a connecting hole is formed between the first coupling groove and the second coupling groove, the motor and the fixed shaft are disposed inside the first coupling groove and the second coupling groove respectively, the output rotating shaft is inserted into the connecting hole, and the output rotating shaft and the roller rotate synchronously; and the output rotating shaft and the roller are arranged on a common central axis, and a length direction of the handle is perpendicular to an axis direction of the output rotating shaft.
Further, the frame includes an arc-shaped plate, the fixed shaft and an electrical installation box are respectively arranged at two ends of an inner arc surface of the arc-shaped plate, the motor is installed inside the electrical installation box, and the output rotating shaft of the motor extends out from the electrical installation box.
Further, a storage battery and a main control circuit board is also arranged inside the electrical installation box, the storage battery supplies power to the main control circuit board and the motor, the main control circuit board is electrically connected to a charging connector, and the storage battery can be charged through the charging connector.
Further, each end of the outer arc surface of the arc-shaped plate is provided with a mounting portion, a certain spacing is reserved between the two mounting portions, and a mounting hole is formed on each of the ends of the two mounting portions that are close to each other; and each side of the end of the handle connected to the frame is provided with a short connecting shaft, and the two short connecting shafts of the handle are respectively mounted in the mounting holes of the two mounting portions.
Further, a coil spring is disposed inside each of the mounting holes of the mounting portions, and the coil springs are connected to the mounting portions and the short connecting shafts, respectively.
Further, the rolling brush includes a brush head or bristles, and the brush head or the bristles is/are arranged on an outer cylindrical surface of the roller.
Compared with the prior art, the present disclosure has the following beneficial effects:
1. In the present disclosure, the motor and the rolling brush are arranged coaxially and horizontally, and the motor is disposed inside an internal space of the rolling brush, such that the rolling brush can rotate horizontally with a cleaning surface, and the rolling brush can also move forwards or backwards, or the rolling brush can rotate in place, making the electric cleaning brush in the present disclosure easy to control and easier to use, and improving cleaning efficiency.
2. In the present disclosure, the coil springs are arranged at the connection between the handle and the brush broom assembly, such that angle and strength of the brush broom assembly and the cleaning surface can be adjusted when in use, making the user more comfortable; and after being used, the brush broom assembly automatically returns to its original position under the restoring force of the coil springs, facilitating the storage and placement of the electric cleaning brush.
In the accompanying drawings: 1. handle; 11. short connecting shaft; 2. brush broom assembly; 21. frame; 211. fixed shaft; 212. arc-shaped plate; 213. electrical installation box; 214. mounting portion; 215. coil spring; 22. motor; 221. output rotating shaft; 23. rolling brush; 231. roller; 2311. first coupling groove; 2312. second coupling groove; 2313. connecting hole; and 232. brush head.
In the present disclosure, unless otherwise explicitly specified and defined, the terms “mounting”, “connecting”, “connection”, “fixing”, etc. should be understood in a broad sense, for example, they may be a fixed connection, a detachable connection, or an integrated connection; may be a mechanical connection, or an electrical connection; may be a direct connection, or an indirect connection via an intermediate medium; and may be communication inside two elements, or an interactive relation between two elements. Those of ordinarily skilled in the art can understand specific meanings of the above terms in the present disclosure according to specific circumstances.
The present disclosure will be further described below in conjunction with the accompanying drawings and specific embodiments:
The motor 22 can have various modes of power supply, including being powered by a power cord and a plug connected to a socket, or being powered by a storage battery. When the motor 22 is powered by the storage battery, the storage battery is arranged inside the electrical installation box 213, in addition, a main control circuit board is also arranged inside the electrical installation box 213, the storage battery supplies power to the main control circuit board and the motor 22, the main control circuit board is electrically connected to a charging connector, and the storage battery can be charged through the charging connector.
As shown in
Working principle of the present disclosure: the motor 22 and the rolling brush 23 are arranged coaxially and horizontally, and the motor 22 is disposed inside an internal space of the rolling brush 23, such that the rolling brush 23 can rotate horizontally with a cleaning surface, and the rolling brush 23 can also move forwards or backwards, or the rolling brush 23 can rotate in place, making the electric cleaning brush in the present disclosure easy to control and easier to use, and improving cleaning efficiency, especially better efficiency when cleaning a ceiling. In addition, the coil springs 215 are arranged at the connection between the handle 1 and the brush broom assembly 2, such that angle and strength of the brush broom assembly 2 and the cleaning surface can be adjusted when in use, making the user more comfortable; and after being used, the brush broom assembly 2 automatically returns to its original position under the restoring force of the coil springs 215, facilitating the storage and placement of the electric cleaning brush.
The above descriptions are only preferred embodiments of the present disclosure, and are not intended to be limiting of the present disclosure, and various changes and modifications may be made by those skilled in the art.
