A floor brush module for a cleaning machine and the cleaning machine

Abstract

This invention relates to a floor brush module for a cleaning machine and the cleaning machine itself. The floor brush module has a dust collection chamber inside its housing, and a brush head is rotatably arranged within the dust collection chamber. A triggering element in the triggering structure, in conjunction with an elastic element, allows the flow distribution unit and the flow guide in the fluid distribution unit to engage or disengage. During normal use of the cleaning machine, the elasticity of the elastic element allows the water and air paths inside the flow distribution unit and the flow guide to be connected separately. With the participation of airflow, the cleaning water is atomized, making it easier to clean stains on the surface. When the cleaning machine moves to a corner, the triggering element forces the flow distribution unit and the flow guide to disengage, allowing water without airflow to be sprayed directly onto the surface to be cleaned. This water, propelled by the airflow, spreads to the corner, ensuring cleaning of the corners and avoiding leaving any cleaning dead zones.

Description

Technical Field

[0001] This invention relates to the field of mobile cleaning equipment, specifically to a floor brush module for a cleaning machine and a cleaning machine. Background Technology

[0002] Existing mobile cleaning equipment has made many adaptive improvements to adapt to environmental changes in different cleaning scenarios. For example, Chinese invention application with patent number CN202010568160.1 (publication announcement number: CN111820816A) discloses "A water purifier dry and wet dual-use sewage tank assembly". A sewage inlet pipe is provided at the bottom of the sewage tank. 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 downstream to the negative pressure source. At the end of the air path of the floor scrubber, that is, on the outer shell of the blower module in the floor scrubber, an air outlet is opened. The airflow drawn by the negative pressure is finally discharged from the air outlet.

[0003] While the aforementioned cleaning machines achieve a certain degree of wet and dry cleaning capability, their lack of optimization for corners and other sensitive areas results in poor cleaning performance in certain areas. To address this, Chinese invention application CN202110852755.4 discloses "A Wet and Dry Vacuum Cleaner with Increased Corner Cleaning Ability." In this vacuum cleaner, a roller brush is mounted at the front of the main housing, ensuring there are no fixed obstructions in front of the brush. This allows the brush to reach corners and other sensitive areas to the maximum extent, significantly increasing its cleaning ability in these areas.

[0004] Although the aforementioned vacuum cleaner has been specially designed to clean corners, the shape of the roller brush itself limits its ability to completely adhere to the corners due to the empty space at the front of the roller brush. This inevitably leaves cleaning dead spots. Furthermore, the water flow remains in a normal state throughout the cleaning process, which also results in insufficient cleaning power for corners. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a floor brush module for a cleaning machine that utilizes the disconnection and connection of a diverter seat and a guide to achieve the supply of cleaning water to the corners.

[0006] The second technical problem to be solved by the present invention is to provide a cleaning machine having the above-mentioned floor brush module, in view of the current state of the prior art.

[0007] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a floor brush module for a cleaning machine, comprising:

[0008] The casing contains a dust collection chamber for collecting solid particles and fluids;

[0009] The brush head is rotatably arranged inside the suction chamber;

[0010] A fluid distribution component, disposed within the housing, includes a flow divider and a flow guide. The flow divider has independent water inlet channels and air inlet channels, and also has a connection port. The flow guide has an air outlet channel and an outlet channel that is always in fluid communication with the water inlet channel. The flow guide is movably constrained on the flow divider to be in a first use state tightly fitted at the connection port or in a second use state disconnected from the connection port. In the first use state, the flow guide is in fluid communication with the air inlet channel and the air outlet channel. In the second use state, the flow guide is disconnected from the connection port, and the outlet end of the air inlet channel is in fluid communication with the dust collection chamber.

[0011] An elastic element acts on the flow guide to ensure that the flow guide always tends to engage with the connector of the flow divider; and

[0012] The triggering structure has a trigger element that is at least partially exposed outside the housing, which can act on the guide under pressure to disengage the guide from the connection port.

[0013] To ensure that the fluid can come into contact with the dust on the surface to be cleaned as soon as possible, preferably, the front side of the housing has a base, and a gap is left between the bottom of the base and the surface to be cleaned to form a dust suction chamber, and the fluid distribution component is disposed on the base and located in front of the dust suction chamber.

[0014] To ensure the restriction of water flow and atomized cleaning water and prevent it from seeping into the housing, preferably, the guide includes a shell, which is strip-shaped and hollow inside to form a downward-facing receiving groove. The front side of the shell has an installation port that extends through the thickness direction at a corresponding position. When the fluid distribution component is assembled on the base, the receiving groove engages with the installation port at the groove opening.

[0015] Specifically, the diverter seat is located around the periphery of the mounting port, and the connection port is located on the side of the diverter seat.

[0016] There are various structures for achieving end-point delivery of cleaning water. Preferably, the outer shell extends along the width of the shell, and the guide member also has a guide end located at the inner end of the outer shell. The two ends of the guide end have ports for engaging with the connection port and mixing nozzles for fluid communication with the receiving tank.

[0017] Specifically, the diverter is located in the middle area of ​​the base, and has connection ports on both sides. There are two flow guides, and the flow guide ends of each flow guide are respectively connected to the corresponding connection ports.

[0018] To facilitate the movement of the fluid distribution components, preferably, the end walls of the outer ends of each of the housings have outwardly extending support rods, and support seats are provided on both sides of the base at corresponding positions, and the support rods are arranged to slide relative to the support seats.

[0019] There are various structures for triggering. Preferably, the trigger is a protruding post that passes through the side of the base, and the protruding post is arranged to reciprocate relative to the base along its own axis.

[0020] Specifically, the triggering structure also has a connecting rod, which extends forward and backward and is rotatably connected to the base. One end of the connecting rod is connected to the support rod, and the other end is located on the moving path of the protrusion. Under pressure, the protrusion moves inward and acts on the connecting rod, so that the connecting rod drives the support rod and the guide to move outward synchronously, thereby putting the fluid distribution component into a second use state where the guide is disengaged from the connection port.

[0021] Preferably, the elastic element is a spring sleeved on the support rod, with both ends of the spring abutting against the outer end wall of the outer shell and the inner side of the support seat, so that the guide element always has a tendency to move inward.

[0022] To further solve the second technical problem mentioned above, the technical solution adopted by the present invention is as follows: a cleaning machine having the above-mentioned floor brush module, and further including a dust separation module and a fan module, wherein the floor brush module, the dust separation module and the fan module are arranged sequentially along the flow direction of the fluid, and the outlet end of the floor brush module is the exhaust port of the housing.

[0023] Preferably, the cleaning machine is a floor scrubber.

[0024] Compared with the prior art, the advantages of the present invention are as follows: In the floor brush module for the cleaning machine, the triggering element in the triggering structure cooperates with the elastic element to enable the flow distribution seat and the flow guide in the fluid distribution component to engage or disengage. When the cleaning machine is in normal use, the elasticity of the elastic element enables the water and air paths inside the flow distribution seat and the flow guide to be connected respectively. With the participation of the airflow, the cleaning water is atomized, making the stains on the surface to be cleaned easier to clean. When the cleaning machine moves to the corner, the triggering element forces the flow distribution seat and the flow guide to disengage, and the water without airflow supply is sprayed directly onto the surface to be cleaned. Under the blowing of the airflow, it can spread to the corner, ensuring the cleaning of the corner and avoiding leaving cleaning dead corners. Attached Figure Description

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] like Figures 1 to 9 The image shows a preferred embodiment of the present invention. In this embodiment, the floor brush module is applicable to a cleaning machine. The cleaning machine mentioned here can be of 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 sequentially along the flow direction of the fluid. 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 includes a housing 1, a brush head 2, a fluid distribution component 3, an elastic component 4, and a triggering structure 5. The housing 1 has a suction chamber 1a for collecting solid particles and fluids. The brush head 2 is used to sweep the surface to be cleaned. The brush head 2 is rotatably arranged in the suction chamber 1a, and in this embodiment, the axis of rotation of the brush head 2 extends vertically.

[0037] In order to achieve different strategies for supplying cleaning water under different conditions, the fluid distribution component 3 in this embodiment is located inside the housing 1 and has a diverter seat 31 and a guide component 32. The water passage between the diverter seat 31 and the guide component 32 is always unobstructed. That is, the diverter seat 31 has an inlet channel 31a inside, and the guide component 32 has an outlet channel 32a that is always in fluid communication with the inlet channel 31a inside. The different cleaning water supply methods mentioned above are caused by the different connection methods of the diverter seat 31 and the guide component 32, which change the direction of the air passage.

[0038] In this embodiment, the diversion seat 31 also has an air inlet channel 31b arranged independently of the water inlet channel 31a, and the diversion seat 31 also has a connection port 310. The guide member 32 has an air outlet channel 32b. Since the guide member 32 can be movably constrained on the diversion seat 31 and can be in a first use state that is tightly fitted at the connection port 310 or in a second use state that is disconnected from the connection port 310, the air inlet channel 31b and the air outlet channel 32b are in fluid communication when the guide member 32 is in the first use state that is tightly fitted at the connection port 310. In the second use state that the guide member 32 is disconnected from the connection port 310, the outlet end of the air inlet channel 31b is in fluid communication with the dust collection 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 collection chamber 1a. The fluid distribution member 3 is disposed on the base 12 and located in front of the dust collection chamber 1a.

[0039] The flow guide 32 in this embodiment includes a housing 321, which is strip-shaped and hollow inside, forming a downward-facing receiving groove 320. A mounting port 13 is provided on the front side of the housing 1, extending through the thickness direction at a corresponding position. When the fluid distribution component 3 is assembled on the base 12, the receiving groove 320 engages with the mounting port 13 at its opening. The aforementioned flow divider 31 is disposed around the periphery of the mounting port 13, and a connection port 310 is provided on the side of the flow divider 31. Specifically, the housing 321 extends along the width direction of the housing 1. The flow guide 32 also has a flow guide end 322 located at the inner end of the housing 321. The two ends of the flow guide end 322 have ports 323 for engaging with the connection port 310 and a mixing nozzle 324 for fluid communication with the receiving groove 320, respectively.

[0040] In this embodiment, the diverter seat 31 is located in the central region of the base 12, and has connection ports 310 on both sides. There are two flow guides 32, and the flow guide ends 322 of each flow guide 32 are respectively engaged with the corresponding connection ports 310. Furthermore, the end walls of the outer ends of each outer shell 321 have outwardly extending support rods 33, and support seats 11 are provided at corresponding positions on both sides of the base 12. The support rods 33 are arranged to slide relative to the support seats 11.

[0041] In this embodiment, the docking or disconnection between the diverter 31 and the guide 32 is achieved through the cooperation of the elastic element 4 and the trigger structure 5. The elastic element 4 is used to engage the two components. The elastic element 4 acts on the guide 32 so that the guide 32 always tends to engage with the connection port 310 of the diverter 31. The elastic element 4 is a spring sleeved on the support rod 33. The two ends of the spring abut against the outer end wall of the outer shell 321 and the inner side of the support base 11, respectively, so that the guide 32 always tends to move inward. The trigger structure 5 is used to drive the diverter 31 and the guide 32 to actively disconnect. The trigger structure 5 has a trigger element 51 that is at least partially exposed outside the shell 1. The trigger element 51 can act on the guide 32 under pressure so that the guide 32 disengages from the connection port 310. In this embodiment, the trigger 51 is a protrusion passing through the side of the base 12, and the protrusion is arranged to reciprocate relative to the base 12 along its own axial direction. 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. One end of the connecting rod 52 is connected to the support rod 33, and the other end is located on the movement path of the protrusion. Under pressure, the protrusion moves inward and acts on the connecting rod 52, so that the connecting rod 52 drives the support rod 33 and the guide member 32 to move outward synchronously, thereby putting the fluid distribution member 3 into a second use state where the guide member 32 is disengaged from the connection port 310.

[0042] The term "fluid connectivity" as used in this invention refers to the spatial relationship between two components or parts (hereinafter referred to as the first part and the second part, respectively), that is, a fluid (gas, liquid, or a mixture of both) can flow from the first part along a flow path and / or be transported to the second part. This can be a direct connection between the first part and the second part, or an indirect connection between the first part and the second part through at least one third party. This third party can be a fluid channel such as a pipe, channel, conduit, guide, hole, or groove, or a chamber or combination thereof that allows fluid to flow through.

[0043] Furthermore, the specification and claims of this invention use terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," to describe various exemplary structural parts and elements of the invention. However, these terms are used herein merely for ease of explanation and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this invention can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
