Description

Technical Field

[0001] This utility model relates to the field of floor cleaning equipment technology, and in particular to a floor cleaning device that can use cleaning fluid to wipe the floor and recycle the used liquid. Background Technology

[0002] Floor cleaning devices, such as floor scrubbers, are highly efficient floor cleaning equipment. They consist of a rotating roller brush, a squeegee, and a wastewater tank. Through the rotation of the roller brush and the cooperation of the squeegee, dirt and liquids on the floor are quickly removed and guided into the wastewater tank by gravity. The wastewater tank, as a key functional module, is usually located near the roller brush to shorten the wastewater flow path. Its structural design directly affects spill prevention performance and ease of user maintenance.

[0003] Currently, most commercially available floor cleaning devices use an open-top design for their wastewater collection boxes. The open area faces directly below the squeegee, allowing wastewater ejected by the roller brush to fall directly into the box. While this structure simplifies the wastewater flow path and reduces flow resistance, the lack of a closed structure at the top means that when the user disassembles the wastewater collection box or when the box tilts due to vibration during operation, the internal liquid is prone to overflowing from the open area due to inertia.

[0004] To address the issue of liquid splashing when disposing of wastewater, some improvements have attempted to add a movable cover to the opening, which can be opened and closed manually or via a spring mechanism. However, this design has significant limitations, such as requiring users to perform an additional action of opening the cover to install or remove the wastewater box, creating operational redundancy. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a floor cleaning device that can seal the wastewater box and requires no additional user intervention.

[0006] Therefore, this utility model provides a floor cleaning device with a floor brush capable of moving along the floor. The floor brush includes: a housing assembly including a main housing and a floor brush cover removably disposed above the main housing; a roller brush, rotatable about its own axis and disposed at the front of the main housing and capable of contacting the floor to be cleaned; a fluid dispenser configured to dispense cleaning fluid to the roller brush; a scraper configured to abut against the roller brush to scrape off excess liquid from the roller brush wetted with cleaning fluid; and a dirt collection box configured to be removably disposed on the main housing and can only be removed from the main housing after the floor brush cover is removed. The dirt collection box includes a box body and a box cover covering the upper part of the box body and removable or openable from the box body. The lid defines a waste collection chamber configured to collect excess liquid scraped from the roller brush by the scraper. The waste collection chamber has one or more waste inlets on the lid. The waste collection box also includes one or more sealing caps disposed on the one or more waste inlets. Each of the sealing caps is switchably arranged on the lid in an open position for opening the corresponding waste inlet and a closed position for closing the corresponding waste inlet, and each of the sealing caps is normally in the closed position. The floor brush cover includes a cover body and one or more triggering elements disposed on the cover body. The one or more triggering elements are configured to trigger the one or more sealing caps to move to the open position when the floor brush cover is mounted on the upper part of the main housing.

[0007] According to one embodiment of the present invention, each of the sealing caps is hinged to the box cover via a hinge shaft, and a spring is also provided between each of the sealing caps and the box cover, the spring being configured to hold the sealing cap in the closed position under normal conditions.

[0008] According to one embodiment of the present invention, the triggering component is a push rod. Each push rod is disposed on the cover body. When the floor brush cover is attached to the upper part of the main housing, each push rod contacts the corresponding sealing cover and causes the sealing cover to move to the open position.

[0009] According to one embodiment of the present invention, each of the sealing covers includes a sealing portion and a force-applying portion located at opposite ends of the hinge shaft, the sealing portion being configured to be adapted to the corresponding sewage inlet; when the floor brush cover is mounted on the upper part of the main housing, each of the top rods abuts against the corresponding force-applying portion.

[0010] According to one embodiment of the present invention, the dirt collection box is located behind the roller brush, and the box body and the box cover further define a solid waste collection chamber; with respect to the rotation direction of the roller brush, the solid waste collection chamber is located upstream of the scraper, and the solid waste collection chamber has a solid waste inlet located on the front side wall of the box body, the solid waste inlet facing the roller brush.

[0011] According to one embodiment of the present invention, the solid waste collection chamber and the wastewater recycling chamber are arranged one in front of the other.

[0012] According to one embodiment of the present invention, the lid defines the upper boundary of the solid waste collection chamber and the upper boundary of the wastewater recovery chamber.

[0013] According to one embodiment of the present invention, the cover is defined for one or more flow ramps that gradually slope downward from front to back, and each of the said sewage inlets is connected to the rear end of the corresponding flow ramp.

[0014] According to one embodiment of the present invention, the scraper strip is integrated on the top cover of the floor brush.

[0015] According to one embodiment of the present invention, the fluid distributor is integrated on the top cover of the floor brush; with respect to the rotation direction of the roller brush, the fluid distributor is located downstream of the scraper.

[0016] According to one embodiment of the present invention, the floor cleaning device further includes: an upright body, the upright body including a housing rotatably connected to the floor brush at its lower part, a liquid supply tank detachably mounted on the housing, and a handle assembly mounted on the upper part of the housing.

[0017] According to one embodiment of the present invention, the triggering component is a magnetic component, and each of the sealing caps is provided with a magnetic component adapted to the magnetic component.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: By providing sealing caps at each sewage inlet of the dirt collection box, when the floor brush cover is not assembled, the sealing caps are tightly closed at the sewage inlet of the dirt collection box, thus sealing the inside sewage and preventing it from flowing out; while when the floor brush cover is assembled, the sealing caps are pushed open by the corresponding triggering components on the floor brush cover, allowing the sewage to flow into the water tank from the sewage inlet; the sealing cap and triggering component structure of this application can effectively prevent sewage from overflowing from the box during the removal or handling of the dirt collection box by the operator.

[0028] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] like Figure 1 As shown, a floor cleaning device 100 is provided, which can wipe the floor with cleaning fluid and recycle the used liquid. The floor cleaning device 100 is configured to wipe the floor (e.g., hard floor such as wood flooring or tile) with liquid without using a suction motor.

[0030] The floor cleaning device 100 includes a floor brush 1 movable along the floor to be cleaned and an upright body 2 located above the floor brush 1. The upright body 2 is typically rotatably connected to the floor brush 1. The upright body 2 includes a housing 21 rotatably connected to the floor brush 1 at its lower part, a liquid supply tank 22 detachably mounted on the housing 21, and a handle assembly 23 mounted on the upper part of the housing 21. The upright body 21 may also include a power source (not shown), which may be a rechargeable battery or a power cord capable of connecting to an external power source. The liquid supply tank 22 can store and supply cleaning fluid (e.g., water, a mixture of solutions with added cleaning solvents, etc.). In some embodiments, the upright body may also be equipped with a steam generator capable of converting the liquid from the liquid supply tank into high-temperature steam and delivering it to the floor brush. In some embodiments, the upright body 2 is also equipped with a pump for outputting the cleaning liquid from the liquid supply tank 22; of course, the pump may also be mounted on the floor brush 1. The positional relationships of "up", "down", "front", and "back" described above and below are defined from the perspective of the operator standing behind the upright machine and pushing the floor brush forward.

[0031] Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the floor brush 1 includes a housing assembly 11 consisting of a main housing 111 and a floor brush cover 112. The housing assembly 11 supports at least some components arranged on the housing assembly 11, such as a roller brush 12, a dirt collection box 13, etc.

[0032] The brush cover 112 is located above the dirt collection box 13 and the roller brush 12 and is removably mounted on top of the main housing 111. The entire brush cover 112 can be injection molded from plastic and can be either a transparent part molded from translucent or transparent material or an opaque part. A locking mechanism 16 is provided between the brush cover 112 and the main housing 111; when the machine user triggers the locking mechanism 16, the brush cover 112 can be released from the main housing 111 to expose the roller brush 12 and the dirt collection box 13; both the roller brush 12 and the dirt collection box 13 are detachable, and after the brush cover 112 is removed from the main housing 111, both the roller brush 12 and the dirt collection box 13 can be removed separately.

[0033] A roller brush 12 is mounted at the front of the main housing 111. The roller brush 12 is configured to rotate about a central axis of rotation X to contact the floor to be cleaned and pick up dirt and liquids on the floor. The roller brush 12 may be a component suitable for wet mopping or sweeping, with its outer peripheral surface covered with fibrous bristles that can be wetted by liquids.

[0034] A fluid distributor 14 and a scraper 15 are integrated on the inner side of the brush cover 112. The fluid distributor 14 faces the roller brush 12 assembly and applies cleaning fluid from the liquid supply tank 22 to the roller brush 12. The scraper 15 contacts the roller brush 12, scraping off dirt or solid debris from it. The fluid distributor 14 is located downstream of the scraper 15 in the direction of rotation of the roller brush 12. A dirt collection box 13 is adjacent to and located behind the roller brush 12. The dirt collection box 13 is detachably supported within the main housing 111.

[0035] The waste collection box 13 includes a box body 131, a lid 132, and a pair of sealing covers 133. The lid 132 is positioned on top of the box body 131 and can be opened. The box body 131 and the lid 132 define a solid waste collection chamber 134 and a wastewater recovery chamber 135. The lid 132 defines the upper boundary of the solid waste collection chamber 134 and the upper boundary of the wastewater recovery chamber 135. The solid waste collection chamber 134 and the wastewater recovery chamber 135 are arranged one in front of the other. With respect to the rotation direction of the roller brush 12, the solid waste collection chamber 134 is located upstream of the scraper 15. The solid waste collection chamber 134 has a solid waste inlet 137 located on the front side wall of the box body 131, facing the roller brush 12. Most of the solid waste picked up by the roller brush 12 can enter the solid waste collection chamber 134 through the solid waste inlet 137 under inertia.

[0036] Each sealing cap 133 is hinged to the cover 132 via a hinge shaft 139. The wastewater recovery chamber 135 has a pair of wastewater inlets 136 located on the cover 132. The pair of sealing caps 133 are adapted to the pair of wastewater inlets 136. Each sealing cap 133 is configurable on the cover 132 to switch between an open position (open) and a closed position (closed) of the corresponding wastewater inlet 136. The wastewater recovery chamber 135 is typically equipped with a liquid level detection mechanism, which allows the user to easily determine whether the liquid level in the wastewater recovery chamber 135 has reached the warning line and requires emptying.

[0037] Combination Figure 6 As shown, each sealing cap 133 includes a hinge portion 1333 that passes through the hinge shaft 139, and sealing portions 1331 and force-applying portions 1332 located at opposite ends of the hinge portion 1333. The sealing portion 1331 is configured to mate with the corresponding sewage inlet 136.

[0038] The cover 132 defines a flow ramp 138 that slopes downwards from front to back, the rear end of which connects to a pair of wastewater inlets 136. The front end of the flow ramp 138 is located below and behind the scraper 15. When the pair of sealing covers 133 are in the open position, excess liquid scraped off the roller brush 12 by the scraper 15 can be directed via the pair of flow ramps 138 to the pair of wastewater inlets 136 and into the wastewater recovery chamber 135.

[0039] Combination Figure 7 As shown, the floor brush cover 112 includes a cover body 1121 and a pair of push rods 1122 disposed on the cover body 1121. The pair of push rods 1122 protrude downward relative to the lower surface of the cover body 1121.

[0040] See Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, when the brush cover 112 is attached to the upper part of the main housing 111, a pair of push rods 1122 respectively contact the force-applying parts 1332 of a pair of sealing covers 133 and cause the sealing covers 133 to move to the open position.

[0041] In some embodiments, a spring (not shown) is also provided between each sealing cap 133 and the cover 132. The spring is configured to hold the corresponding sealing cap 133 in the closed position after all external forces applied to the corresponding sealing cap 133 (such as the external force applied by the push rod 1122 to the force application part 1332) are completely removed. That is, each spring can keep the corresponding sealing cap in the closed position under normal conditions. Exemplarily, the spring is a torsion spring; of course, a tension spring or a compression spring can also be used instead of a torsion spring. In this example, after the top cover 112 of the ground brush is removed from the main housing 111, the pair of sealing caps 133 will automatically return to the normally closed position, thereby effectively preventing the sewage recovery chamber 135 from leaking from the pair of sewage inlets 136 when the user removes or moves the sewage collection box 13.

[0042] When the floor cleaning device 100 performs floor cleaning work, the roller brush 12 and the dirt collection box 13 are both installed at corresponding positions on the main housing 111. The floor brush cover 112 is installed on the upper part of the main housing 111 and covers the roller brush 12 and the dirt collection box 13 from above. The fluid distributor 14 on the floor brush cover 112 approaches the roller brush 12, and the scraper 15 abuts against the roller brush 12. A pair of push rods 1122 on the floor brush cover 112 abut against the force application part 1332 of a pair of sealing covers 122, and the pair of sealing covers 122 are triggered open by the pair of push rods 1122. The roller brush 12 continues to rotate to pick up solid debris and dirt on the floor to be cleaned, thereby achieving the purpose of cleaning the working surface. During one rotation cycle of the roller brush 12, it is first wetted by the cleaning fluid applied by the fluid distributor 14, and then comes into contact with the ground to be cleaned. Solid waste and sewage on the ground to be cleaned will adhere to the outer peripheral surface of the roller brush 12. Due to the centrifugal force of the roller brush 12, some larger pieces of waste will detach from the roller brush 12 and enter the solid waste collection chamber 134 through the solid waste inlet 137. Some smaller or more adherent waste will remain on the roller brush 12. When it moves to the scraper 15, these smaller or more adherent pieces of waste, along with the liquid wetting the roller brush 12, will be scraped off by the scraper 15. The waste will then be led through a pair of guide ramps 138 to a pair of sewage inlets 136 and fall into the sewage recovery chamber 135.

[0043] When the waste collection chamber 135 in the waste collection box 13 is full, the user first needs to remove the brush cover 112, and then the housing will remove the waste collection box 13. After the brush cover 112 is removed, as the brush cover 112 leaves the main housing 111, the pair of push rods 1122 on the brush cover 112 will also leave the pair of sealing covers 122. The pair of sealing covers 122 will return to the closed position under the action of the spring and close the pair of waste inlets 136, thereby sealing the waste collection chamber 135. The waste inside the waste collection chamber 135 cannot flow out, and the user can disassemble or move the waste collection box 13 without any burden.

[0044] In some embodiments, the top rod 1122 on the brush cover 112 can be omitted, and a magnetic attraction scheme can be used to trigger the corresponding sealing cover to the open position. A feasible scheme is to provide one or more magnetic attraction components in the brush cover 112 and magnetic components in each sealing cover. By utilizing the mutual attraction between the magnetic attraction components and the magnetic components, the corresponding sealing cover is triggered to move to the open position when the brush cover 112 covers the dirt collection box 13. After the brush cover 112 is separated from the dirt collection box 13, the sealing cover is normally kept in the closed position under the action of the spring.

[0045] The solution for opening and closing the sewage inlet with the sealing cap of this application is not limited to use on upright floor cleaning devices, but can also be used on canister-type and shoulder-mounted floor cleaning devices; by selectively closing the sewage inlet without user operation, it prevents sewage from leaking out of the dirt collection box, which greatly improves the user experience.

[0046] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
