[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: like Figures 1-5 As shown, a sweeper with an easily replaceable brush head according to an embodiment of the present invention includes a sweeper housing 1, which serves as an external protective layer for the sweeper. This housing is typically made of durable plastic and not only protects internal electronic components from dust and moisture, but also has ventilation openings for heat dissipation. A maintenance component 2 is located on one side of the sweeper housing 1. The maintenance component 2 includes two transmission structures 201 internally arranged within the sweeper housing 1. Each transmission structure 201 is driven by a main motor through a series of mechanical transmission devices (such as gears, belts, or...). Composed of connecting rods, etc., it is used to simultaneously drive the side brush 4 and the roller brush 3. The two ends of the transmission structure 201 pass through the sweeper housing 1 and are respectively provided with a maintenance cylinder 202 and a limiting post 203. The maintenance cylinder 202 has a disassembly groove 204. The two sides inside the disassembly groove 204 are provided with limiting spring pieces 205, which are used to limit the limiting plate 206. One end of the limiting spring piece 205 contacts the limiting plate 206, which is used to limit the installed roller brush 3. One end of the limiting post 203 is threadedly connected to a limiting block 207, which is used to limit the side brush 4. A roller brush 3 is installed on one side of the limiting plate 206 and inside the maintenance cylinder 202. It is used to rotate at high speed to grab and sweep dust and debris on the ground. A side brush 4 is installed at the opposite end of the limiting column 203 and the limiting block 207. It is used to sweep the garbage from the edge or corner to the center so that the roller brush 3 can collect it. An auxiliary frame 5 is installed inside the sweeper housing 1. It is used to collect and process the cleaned impurities. A dust suction structure 11 is installed inside the auxiliary frame 5. The dust suction structure 11 consists of a vacuum cleaner, a dust collection box and other components. It generates negative pressure to attract dust into the dust collection box, which is used to store the sucked-in dust and garbage. The dust collection box is also equipped with a filter, such as a HEPA filter, to capture fine particles and ensure that the exhaust air is clean. The two sides of the auxiliary frame 5 are connected through the transmission structure 201. The maintenance cylinder 202 and the roller brush 3 are located inside the auxiliary frame 5.

[0019] Example 2: like Figures 1-3 As shown, according to an embodiment of this utility model, a sweeping machine with an easy-to-change brush head has two snap-fit ​​slots inside the auxiliary frame 5, and a protective mesh plate 6 is snapped inside the snap-fit ​​slots to provide auxiliary protection for the roller brush 3. Two drive slots are provided at the bottom of the sweeping machine housing 1. Drive motors 7 are installed inside drive slots 1 and 1 to drive drive wheels 8. One end of the drive motor 7 is equipped with a drive wheel 8 for moving the sweeping machine. A second drive slot is provided at the bottom of the sweeping machine housing 1, and a universal wheel 9 is installed inside the second drive slot to assist the movement of the drive wheel 8. Multiple detection structures 10 are provided on the sweeping machine housing 1. Each detection structure 10 consists of a collision sensor, a cliff sensor (anti-fall sensor), and an optical or laser navigation system (camera, laser rangefinder, etc.). Collision sensor: used to detect if the robot vacuum cleaner collides with an obstacle and change its direction of travel in time; cliff sensor (anti-fall sensor): located on the bottom of the robot vacuum cleaner, used to detect edge positions such as stairs to prevent it from falling; optical or laser navigation system: including cameras, laser rangefinders, etc., used to map the room and plan the cleaning path. The detection structure 10, drive motor 7, suction structure 11, and transmission structure 201 are electrically connected to a controller (not shown in the figure) during actual use. The controller is a PLC (Programmable Logic Controller) or a microcontroller. The specific working control program of the controller is written and set according to the actual situation, which is conducive to the precise control of the electrically connected electrical components. The above structures are electrically connected to a battery during actual use. The battery is a rechargeable battery. The battery is electrically connected to a charging system during actual use. The charging system includes an automatic recharging function. When the battery is low, the robot vacuum cleaner can automatically return to the charging dock for charging. The detection structure 10, drive motor 7, dust collection structure 11, and transmission structure 201 are existing technologies and will not be described in detail. The specific model and specifications need to be selected and determined according to the actual specifications of the device.

[0020] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0021] In summary, with the help of the above-mentioned technical solution of this utility model, when it is necessary to replace the brush head, the limiting block 207 can be rotated to remove it from the limiting post 203. Then, the protective mesh plate 6 can be removed from the auxiliary frame 5. After removal, the limiting plate 206 can be taken out from the disassembly groove 204 of the maintenance cylinder 202, thereby removing the maintenance cylinder 202 from the sweeper housing 1. The new side brush 4 can be installed on the opposite end of the limiting post 203 and the limiting block 207, and the limiting block 207 can be re-threaded to the limiting post 203. At the same time, the new roller brush 3 can be installed inside the maintenance cylinder 202. After installation, the limiting plate 206 can be engaged with the disassembly groove 204 of the maintenance cylinder 202. At the same time, one end of the limiting spring piece 205 can be pressed against the limiting plate 206, thereby completing the reinstallation. After installation, the protective mesh plate 6 can be engaged with the auxiliary frame 5, which can provide auxiliary protection for the roller brush 3 and prevent debris from directly contacting the roller brush 3 and causing damage. When the sweeper is working, the drive motor 7 drives the drive wheel 8 and the caster wheel 9, enabling the sweeper to move along the planned path. The transmission structure 201, driven by the main motor, simultaneously drives the side brush 4 and the roller brush 3 to rotate. The side brush 4 sweeps the garbage from the edge or corner to the center, while the roller brush 3 rotates at high speed to grab and sweep up the dust and debris on the ground. At the same time, the negative pressure generated by the suction structure 11 attracts the dust into the dust collection box, thereby achieving the cleaning of the ground and the collection of garbage. Meanwhile, the collision sensor, cliff sensor, and optical or laser navigation system in the detection structure 10 continuously detect the surrounding environment, providing the robot vacuum with auxiliary functions such as obstacle avoidance, fall prevention, and path planning, ensuring that the robot vacuum can complete the cleaning task safely and efficiently.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
