Description

Technical Field

[0001] The invention relates to the field of mobile cleaning equipment, and in particular to a floor brush module for a cleaning machine and a cleaning machine. Background Art

[0002] Existing mobile cleaning equipment has made many adaptability improvements to meet environmental changes in different cleaning scenarios. For example, the Chinese invention application with patent number CN202010568160.1 (public announcement number: CN111820816A) discloses "A water machine wet and dry dual-purpose sewage tank assembly". A sewage inlet pipe is provided at the bottom of the sewage tank, and the filter assembly is placed inside the sewage tank and sleeved on the sewage inlet pipe. The tank cover assembly is installed on the sewage tank. After the mixed fluid passes through the sewage tank, the liquid and solid remain in the sewage tank, while the airflow continues to flow toward the downstream negative pressure source. An air outlet is provided at the end of the air path of the floor scrubber, that is, on the outer shell of the fan module in the floor scrubber, and the airflow absorbed by the negative pressure is finally discharged from the air outlet.

[0003] Although the above-mentioned cleaning machine achieves a certain degree of wet and dry dual-purpose, it is not optimized for positions such as corners, and the cleaning effect is not good in some corners. To this end, the Chinese invention application with patent number CN202110852755.4 discloses "A wet and dry dual-purpose vacuum cleaner with increased corner cleaning ability". In this vacuum cleaner, by installing the roller brush at the front end of the main shell, there is no fixed obstruction in front of the roller brush, and the roller brush can roll to the corners and other corners to the greatest extent, greatly increasing the cleaning ability of the roller brush to the corners.

[0004] Although the above-mentioned vacuum cleaner has specially improved the structure for cleaning corners, since only the front side of the roller brush is vacant and is limited by the shape of the roller brush itself, it still cannot completely adhere to the corners, thus inevitably leaving cleaning dead corners, and during the entire cleaning stage, the water channel is still in a normal water outlet state, which also leads to insufficient cleaning strength at the corners. Summary of the invention

[0034] The present invention is further described in detail below with reference to the accompanying drawings.

[0035] like Figures 1 to 9 As shown, it is a preferred embodiment of the present invention. In this embodiment, the floor brush module is suitable for use in a cleaning machine. The cleaning machine mentioned here can be different types of mobile cleaning equipment. Taking a floor scrubber as an example, in addition to the floor brush module, it also includes a dust separation module 102 and a fan module 103. The floor brush module 101, the dust separation module 102 and the fan module 103 are arranged in sequence along the flow direction of the fluid, and the outlet end of the floor brush module 101 is the exhaust port of the housing 1.

[0036] The floor brush module for the cleaning machine comprises a housing 1, a brush head 2, a fluid distribution member 3, an elastic member 4 and a trigger structure 5. The housing 1 has a dust suction chamber 1a for collecting solid particles and fluids, the brush head 2 is used to sweep the surface to be cleaned, and the brush head 2 is rotatably arranged in the dust suction chamber 1a, and the rotation axis of the brush head 2 in this embodiment extends vertically.

[0037] In order to realize different strategies for supplying cleaning water under different conditions, the fluid distribution component 3 in this embodiment is arranged in the shell 1 and has a diverter seat 31 and a guide member 32. The water path between the diverter seat 31 and the guide member 32 is always unobstructed, that is, the diverter seat 31 has an inlet channel 31a inside, and the guide member 32 has an outlet channel 32a that is always fluidly connected to the inlet channel 31a. The above-mentioned different cleaning water supply methods are caused by the different connection methods between the diverter seat 31 and the guide member 32, which changes the direction of the air path.

[0038] The diverter seat 31 in this embodiment also has an inlet flow channel 31b arranged independently from the water inlet flow channel 31a, and the diverter seat 31 also has a docking port 310, and the guide member 32 has an outlet flow channel 32b. Since the guide member 32 can be movably constrained on the diverter seat 31, and can be in a first use state tightly fitted at the docking port 310 or a second use state disengaged from the docking port 310, when the guide member 32 is in the first use state tightly fitted at the docking port 310, the inlet flow channel 31b and the outlet flow channel 32b are in fluid communication, and in the second use state when the guide member 32 is disconnected from the docking port 310, the outlet end of the inlet flow channel 31b is in fluid communication with the dust suction chamber 1a. Specifically, the front side of the housing 1 has a base 12, and a gap is left between the bottom of the base 12 and the surface to be cleaned to form a dust suction chamber 1a, and the fluid distribution member 3 is arranged on the base 12 and located at the front side of the dust suction chamber 1a.

[0039] The flow guide 32 in this embodiment includes a shell 321, which is strip-shaped and hollow inside to form a receiving groove 320 with an opening facing downward. The front side of the shell 1 is provided with a mounting opening 13 penetrating along the thickness direction at a corresponding position. When the fluid distribution member 3 is assembled on the base 12, the receiving groove 320 is engaged with the mounting opening 13 at the notch. The flow diverter seat 31 is arranged at the periphery of the mounting opening 13, and the connection port 310 is provided at the side of the flow diverter seat 31. The shell 321 is specifically arranged to extend along the width direction of the shell 1. The flow guide 32 also has a flow guide terminal 322 provided at the inner end of the shell 321. The two ends of the flow guide terminal 322 respectively have a port 323 for engaging with the connection port 310 and a mixing nozzle 324 in fluid communication with the receiving groove 320.

[0040] The flow diverter seat 31 in this embodiment is arranged in the middle area of ​​the base 12, and has a connection port 310 on both sides thereof. There are two flow guide members 32, and the flow guide end 322 of each flow guide member 32 is respectively engaged with the corresponding connection port 310. The end wall of the outer end of each shell 321 has a support rod 33 extending outward, and the support seats 11 are arranged at corresponding positions on both sides of the base 12, and the support rod 33 is arranged to be able to slide relative to the support seat 11.

[0041] In this embodiment, the docking or disconnection between the diverter seat 31 and the guide member 32 is achieved by the cooperation of the elastic member 4 and the trigger structure 5. The elastic member 4 is used to make the two engage. The elastic member 4 acts on the guide member 32 so that the guide member 32 always has a tendency to engage with the docking port 310 of the diverter seat 31. The elastic member 4 is a spring sleeved on the support rod 33. The two ends of the spring are respectively against the outer end wall of the shell 321 and the inner side of the support seat 11, so that the guide member 32 always has a tendency to move inward. The trigger structure 5 is used to drive the diverter seat 31 and the guide member 32 to actively disconnect. The trigger structure 5 has a trigger member 51 that is at least partially exposed outside the shell 1. The trigger member 51 can act on the guide member 32 under pressure to make the guide member 32 disengage from the docking port 310. The trigger member 51 in this embodiment is a convex column penetrating the side of the base 12, and the convex column is arranged to be reciprocatingly movable along its own axial direction relative to the base 12. In addition, the trigger structure 5 also has a connecting rod 52, which extends forward and backward and is rotatably connected to the base 12 at its middle part, and one end of the connecting rod 52 is connected to the support rod 33, and the other end is located on the moving path of the convex column. Under pressure, the convex column moves inward and acts on the connecting rod 52, so that the connecting rod 52 drives the support rod 33 and the flow guide 32 to move outward synchronously, so that the fluid distribution member 3 is in the second use state where the flow guide 32 is disengaged from the connection port 310.

[0042] The "fluid connection" referred to in the present invention refers to the spatial position relationship between two parts or parts (hereinafter collectively referred to as the first part and the second part respectively), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path or / and be transported to the second part. The first part and the second part can be directly connected, or the first part and the second part can be indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, channel, duct, guide member, hole, groove, etc., or it can be a chamber allowing fluid to flow through, or a combination of the above.
