Description

Technical Field

[0001] This application relates to the field of cleaning tool technology, and more specifically to a floor brush with a built-in motor. Background Technology

[0002] Floor brushes in cleaning tools typically work in conjunction with the machine body to vacuum and clean floors. Patent application number 202411915746.5 discloses a floor scrubber, which includes a base, an adjustment assembly, a fan assembly, a squeegee, and a drive assembly. The base has a receiving cavity, and a dirt inlet communicating with the cavity is located at the bottom of the base. The adjustment assembly is movably fitted into the receiving cavity. The fan assembly is at least partially fitted into the receiving cavity, forming a dirt inlet channel with the adjustment assembly at a distance. The dirt inlet communicates with the dirt inlet channel and is located between the adjustment assembly and the fan assembly. The drive assembly is fitted into the receiving cavity and is driven by the adjustment assembly, used to move the adjustment assembly closer to or away from the fan assembly. The base of this floor scrubber needs to be connected to the fan assembly inside the machine body through the dirt inlet channel and air duct, resulting in a relatively long airflow path. This leads to a loss of suction power in the motor, affecting the cleaning effect. Summary of the Invention

[0030] Combination Figures 1-8 As shown, this application provides a floor brush cleaning tool with a built-in motor, including a floor brush base 1, a suction motor assembly mounted on the floor brush base 1, an air guide cavity 2 communicating with the outside inside the floor brush base 1, the suction motor assembly including a suction motor 4, a motor base 6 on the floor brush base 1, the suction motor 4 fixed on the motor base 6, and air inlets 8 symmetrically arranged on both sides of the motor base 6, the air inlets 8 communicating with the air guide cavity 2. The suction motor 4 is used to draw outside air into the air guide cavity 2 and discharge it from the floor brush base 1; specifically, the suction motor assembly also includes a front motor cover 3 and a rear motor cover 5, the suction motor... The motor 4 is fixed to the motor base 6 by the front cover 3 and the rear cover 5 of the motor. The suction motor 4 is provided with sealing rings between the front cover 3 and the rear cover 5 of the motor, and a sealing strip is also installed at the bottom of the front cover 3 for sealing connection with the motor base 6. In this embodiment, the front cover 3 of the motor is provided with an air guide channel 9, which connects the suction motor 4 and the air inlets 8 at both ends. The air guide channel 9 allows the suction motor 4 to absorb the air in the air guide cavity 2. The rear cover 5 of the motor is provided with an air outlet pipe 10 that connects to the outside of the floor brush base 1, and the air drawn in is discharged to the outside through the air outlet pipe 10.

[0031] In some embodiments, such as Figures 1-3As shown, a wastewater tank assembly is installed on the brush base 1. The wastewater tank assembly includes a roller brush 11 and a housing 12 disposed on one side of the roller brush 11. The housing 12 is installed on the brush base 1 and has a wastewater chamber 13 inside. The roller brush 11 is connected to the wastewater chamber 13 through a suction channel 14. The wastewater chamber 13 has an air duct 7, which is connected to an air inlet 8 through an air guide chamber 2. When the suction motor 4 is running, it can connect to the inside of the wastewater chamber 13 through the air inlet 8, the air guide chamber 2, and the air duct 7, thereby absorbing the air in the wastewater chamber 13 and discharging it to the outside, thus realizing the dust and dirt suction function. A series of air ducts are all set inside the brush base 1, reducing airflow loss and thus improving the suction power of the fan. Specifically, a filter assembly is provided between the wastewater tank assembly and the floor brush base 1. The filter assembly includes a filter 15 and a sealing coating 16. The upper end of the filter 15 is fixed to the bottom of the housing 12 by the sealing coating 16, and the lower end of the filter 15 is fixed to the floor brush base 1 by the sealing coating 16. The filter 15 protrudes at the air inlet 8 and the air inlet 8 is sealed by the sealing coating 16. An air guide cavity 2 is formed between the floor brush base 1 and the filter 15. The air in the wastewater tank 13 flows through the air duct 7 and then through the filter 15 in the air guide cavity 2, and finally enters the suction motor 4 through the air inlet 8. The sealing coating 16 can prevent the wastewater and impurities in the wastewater tank 13 from being carried into the suction motor 4.

[0032] In some embodiments, such as Figure 2 and Figure 6 As shown, the air duct 7 is symmetrically arranged at the upper end of the sewage chamber 13 via the mounting base 17. The mounting base 17 is equipped with a sealing element 20 via the mounting bracket 18 and spring 19. The spring 19 pushes the sealing element 20 to seal the air duct 7. A flip-up sealing cover 21 is installed on the sewage suction channel 14. The sealing cover 21 is kept in the normal state by a torsion spring to seal the sewage suction channel 14, preventing sewage from overflowing from the sewage chamber 13. After the suction motor 4 is running, both the sealing element 20 and the sealing cover 21 will be opened, and sewage suction will be performed at this time.
