[0002] With the continuous development of technology and the improvement of people's living standards, new household appliances such as floor washing machines and other household cleaning equipment have increasingly appeared in people's lives.

[0003] In related technologies, cleaning equipment such as floor washing machines includes a floor brush device, and the floor brush device includes a clean water tank, a roller brush, and a water pump. The water pump is used to pump the cleaning water in the clean water tank to the roller brush to wet the roller brush, so as to improve the effect of the roller brush cleaning the ground or for the self-cleaning of the roller brush.

[0004] However, in related technologies, the cleaning effect of the cleaning equipment is poor and the service life is short. Summary of the Utility Model

[0005] Embodiments of the utility model provide a floor brush device and a cleaning equipment, which are used to improve the cleaning effect and extend the service life of structures such as a clean water tank, a water pipe, and a water pump.

[0006] In order to achieve the above purpose, the embodiments of the present application provide the following technical solutions:

[0007] A first aspect of an embodiment of the present application provides a floor brush device, including: a floor brush main body, a cleaning member, and a water tank assembly. The cleaning member is connected to the floor brush main body, and the water tank assembly is disposed on the floor brush main body; the water tank assembly has a clean water chamber and a cleaning liquid chamber. The cleaning liquid chamber has a liquid outlet communicating with the clean water chamber, and the cleaning liquid chamber is configured to add cleaning liquid into the clean water chamber through the liquid outlet; the clean water chamber has a clean water outlet, and the clean water chamber is configured to supply cleaning water to the cleaning member through the clean water outlet; the liquid outlet is located on a side of the cleaning liquid chamber facing the clean water outlet.

[0008] In the floor brush device provided by the embodiments of the present application, by designing a clean water chamber and a cleaning liquid chamber in the water tank assembly, the cleaning liquid chamber has a liquid outlet communicating with the clean water chamber. The cleaning liquid chamber is used to hold the cleaning liquid, and the cleaning liquid in the cleaning liquid chamber is added into the clean water chamber through the liquid outlet, so that the cleaning liquid is mixed and diluted with the cleaning water in the clean water tank and then supplied to the cleaning member through the clean water outlet. In this way, the cleaning effect of the cleaning member when cleaning the ground and self-cleaning can be improved; in addition, by setting the liquid outlet on the side of the cleaning liquid chamber facing the clean water outlet, the cleaning liquid is mixed and diluted with the cleaning water at a position close to the clean water outlet, so as to reduce the area covered by the cleaning liquid in the clean water chamber, thereby reducing the corrosion of the cleaning liquid on the water tank assembly, and further ensuring the service life of the water tank assembly.

[0009] In some embodiments, the fresh water outlet is located at the bottom wall of the fresh water chamber, and the liquid outlet is arranged facing the bottom wall of the fresh water chamber.

[0010] With such an arrangement, the position of the liquid outlet relative to the fresh water outlet is shortened, enabling the cleaning liquid to be quickly mixed and diluted at the fresh water outlet and then quickly supplied to the cleaning member through the fresh water outlet, reducing the residue of the cleaning liquid in the fresh water chamber, thereby further reducing the corrosion of the cleaning liquid on the water tank and ensuring the service life of the fresh water tank.

[0011] In some embodiments, a water outlet valve is provided at the fresh water outlet, and the liquid outlet is located on the side of the water outlet valve.

[0012] With such an arrangement, the water outlet valve can control the inflow and outflow of water at the fresh water outlet. The liquid outlet is arranged on the side of the water outlet valve, allowing the cleaning liquid to quickly mix and dilute with the cleaning water near the water outlet valve after flowing out from the liquid outlet and then quickly flow out from the water outlet valve, further reducing the corrosion of the cleaning liquid on the water tank.

[0013] In some embodiments, the water outlet valve includes a valve body, a valve core, and a first elastic member. The valve body is connected to the inner wall of the fresh water chamber and is opposite to the fresh water outlet. The side wall of the valve body has a water inlet hole; the valve core is movably arranged in the valve body to close or open at least one of the fresh water outlet and the water inlet hole; the first elastic member abuts against the valve core, and the first elastic member is configured to apply a force towards the fresh water outlet to the valve core.

[0014] With such an arrangement, when water is not needed, such as when the water tank assembly is removed from the floor brush body, the valve core can be pressed against the fresh water outlet under the action of the first elastic member to block the fresh water outlet and prevent water leakage. When water is needed, such as when the water tank assembly is installed on the floor brush body, the valve core is pushed up a certain distance by an external force, and the first elastic member is compressed, thereby opening the fresh water outlet. The water in the fresh water chamber flows out of the fresh water chamber through the water inlet formed in the valve body and flows out from the fresh water outlet to achieve the cleaning purpose.

[0015] In some embodiments, the liquid outlet is provided with a fixing portion protruding into the fresh water chamber; the water tank assembly further includes a first one-way valve sleeved outside the fixing portion, and the liquid outlet is in one-way communication with the fresh water chamber through the first one-way valve.

[0016] With such an arrangement, the first one-way valve can be stably sleeved outside the fixing portion, and the liquid outlet conveys to the fresh water chamber unidirectionally through the first one-way valve, preventing the backflow of the cleaning water into the cleaning liquid chamber, ensuring the self-concentration of the cleaning liquid in the cleaning liquid chamber, and avoiding waste and affecting the subsequent cleaning effect.

[0017] In some embodiments, an installation groove is provided at the top of the cleaning liquid chamber, and a through hole communicating the inside and outside of the cleaning liquid chamber is provided in the installation groove; a pressing assembly is provided in the installation groove, and the pressing assembly is configured to press the cleaning liquid in the cleaning liquid chamber into the clear water chamber.

[0018] With such a setting, the user can intermittently press a quantitative amount of cleaning liquid into the clear water chamber through the pressing assembly located at the top of the cleaning liquid chamber, so as to add the cleaning liquid as needed, prevent excessive addition of the cleaning liquid, and the operation is fast, improving the cleaning efficiency. At the same time, the pressing assembly is arranged in the installation groove, which also ensures the structural integrity of the water tank assembly.

[0019] In some embodiments, the pressing assembly includes a pressing member, a fixing frame, a second elastic member and a first sealing member; the pressing member is connected to the fixing frame; at least part of the fixing frame is inserted into the through hole; the first sealing member is sleeved on the outside of the fixing frame and abuts against the inner wall of the through hole; the second elastic member abuts between the bottom wall of the installation groove and the fixing frame, and the second elastic member is configured to apply a force towards the outside of the installation groove to the fixing bracket.

[0020] With such a setting, when the pressing member is not pressed, it is subject to the elastic force of the second elastic member, and the first sealing member effectively seals and cooperates with the through hole, preventing the cleaning liquid from leaking through the through hole. When it is necessary to add the cleaning liquid, the user applies a force to the pressing member, the second elastic member is compressed, the fixing member moves towards the inside of the installation groove, and then the internal space of the cleaning liquid chamber is squeezed, forcing the cleaning liquid to flow into the clear water chamber from the liquid outlet, realizing a fast and stable addition of the cleaning liquid.

[0021] In some embodiments, the pressing assembly further includes a second one-way valve, the second one-way valve is connected to the fixing frame, the pressing member is provided with an air inlet hole, the air inlet hole is opposite to the air inlet end of the second one-way valve, and the second one-way valve is configured to make the air inlet hole communicate with the through hole unidirectionally.

[0022] With such a setting, when the pressing member is pressed and the air pressure inside and outside the cleaning liquid chamber is unbalanced and cannot be reset, the air in the cleaning liquid chamber will sequentially flow into the inside of the cleaning liquid chamber through the air inlet hole, the second one-way valve and the through hole, realizing the balance of the internal and external air pressures, and enabling the pressing member to be reset smoothly.

[0023] In some embodiments, a water filling port is provided at the top of the clear water chamber, and a first sealing plug is provided at the water filling port, and the first sealing plug is sealingly connected to the water filling port; and / or, a liquid adding port is provided at the top of the cleaning liquid chamber, and a second sealing plug is provided at the liquid adding port, and the second sealing plug is sealingly connected to the liquid adding port.

[0024] With such a setting, cleaning water can be quickly replenished into the clean water chamber through the water filling port, and after the replenishment is completed, the first sealing plug is used to prevent the leakage of the cleaning water. And through the liquid filling port, cleaning liquid can be quickly replenished into the cleaning liquid chamber, and after the replenishment is completed, the second sealing plug is used to prevent the leakage of the cleaning liquid. Furthermore, the quick separate replenishment of the cleaning water and the cleaning liquid is achieved.

[0025] In some embodiments, the water tank assembly includes a clean water tank, and the clean water tank has an independent clean water chamber and a cleaning liquid chamber.

[0026] With such a setting, the clean water chamber and the cleaning liquid chamber are independent of each other, and can separately store a fixed amount of cleaning water and cleaning liquid, and can prevent the cleaning water and the cleaning liquid from being mixed in advance, further preventing the cleaning liquid from corroding the clean water chamber and improving the service life.

[0027] In some embodiments, the clean water tank includes a first housing, a second housing and a third housing. The first housing and the second housing are connected and jointly enclose to form the clean water chamber; the third housing is disposed in the clean water chamber, and the third housing encloses to form the cleaning liquid chamber; or, the third housing is connected to one of the first housing and the second housing and jointly encloses to form the cleaning liquid chamber.

[0028] With such a setting, the first housing, the second housing and the third housing are combined together to form the clean water tank, and the third housing is located in the clean water chamber. The formed cleaning liquid chamber is also entirely located in the clean water chamber, further reducing the distance between the liquid outlet and the clean water outlet of the clean water chamber, improving the adding efficiency of the cleaning liquid into the cleaning water, and further reducing the contact time of the cleaning liquid with the clean water chamber, preventing the corrosion of the clean water chamber.

[0029] In some embodiments, the third housing encloses to form the cleaning liquid chamber, and the third housing is detachably connected to the clean water tank.

[0030] With such a setting, the third housing is a separate detachable part, and the cleaning liquid chamber formed by it can be detached from the clean water tank. Furthermore, it is possible to clean only with the cleaning water, and at the same time, the cleaning liquid chamber can be quickly cleaned.

[0031] In some embodiments, the third housing is connected to one of the first housing and the second housing and jointly encloses to form the cleaning liquid chamber, and a first positioning portion is provided at the circumferential edge of the third housing, and a second positioning portion is provided on one of the first housing and the second housing; at least a part of the first positioning portion is hermetically connected to the second positioning portion.

[0032] With such a setting, when it is necessary to add cleaning liquid for cleaning, the third housing can be quickly fitted and connected with the second positioning part in the first housing or the second housing through the first positioning part, and a seal can be achieved to quickly form a sealed cleaning liquid cavity, meeting the usage requirements.

[0033] In some embodiments, the first positioning part is one of a positioning groove and a positioning rib, the second positioning part is the other of the positioning groove and the positioning rib, and at least a part of the positioning rib is inserted into the positioning groove.

[0034] With such a setting, the positioning groove and the positioning rib are connected by means of insertion. Furthermore, quick alignment connection can be achieved between the third housing and the first housing or the second housing, improving the assembly efficiency.

[0035] In some embodiments, an anti-corrosion layer is provided on the cavity wall of the cleaning liquid cavity.

[0036] With such a setting, the anti-corrosion layer can prevent the cavity wall of the cleaning liquid cavity from being corroded by the cleaning liquid, thereby improving the service life of the cleaning liquid cavity.

[0037] In some embodiments, the floor brush device further includes a water pump and a water spraying assembly. The water pump is arranged on the floor brush main body, and the water spraying assembly is connected with the water tank assembly; the water inlet of the water pump is communicated with the clean water outlet, and the water outlet of the water pump.

[0038] With such a setting, the water pump can suck the cleaning water mixed with the cleaning liquid from the clean water outlet and supply the liquid to the cleaning part through the water spraying holes of the water spraying assembly, so that the cleaning part remains wet and the cleaning effect is improved. At the same time, the water pump directly sucks the cleaning water mixed with the cleaning liquid, and there is no need to suck the cleaning liquid and the cleaning water separately and then mix them, improving the liquid supply efficiency to the cleaning part.

[0039] In some embodiments, a second sealing member is provided at the clean water outlet, and the second sealing member abuts against the inner wall of the water inlet of the water pump; and / or, a third sealing member is provided at the water outlet of the water pump, and the third sealing member abuts against the inner wall of the water inlet of the water spraying assembly.

[0040] With such a setting, the second sealing member enables the cleaning water mixed with the cleaning liquid flowing out of the clean water outlet to smoothly enter the water inlet of the water pump without leakage. And the third sealing member can prevent the cleaning water mixed with the cleaning liquid from leaking from the water outlet of the water pump, ensuring the efficient delivery of the cleaning water mixed with the cleaning liquid to the water spraying assembly.

[0041] In some embodiments, the floor brush device further includes a scraping strip, the scraping strip is connected with the outer wall of the water tank assembly, and the scraping strip abuts against the cleaning part.

[0042] With such a setting, the squeegee can scrape off the sundries adhering to the cleaning member and scrape out the cleaning water mixed with the cleaning liquid infiltrated on the cleaning member onto the surface to be cleaned, thereby improving the cleaning effect.

[0043] In some embodiments, a latch and a third elastic member are provided outside the water tank assembly. The latch is movably connected to the water tank assembly. A locking groove is provided on the floor brush main body. The latch can be inserted into the locking groove or disengaged from the locking groove; the third elastic member abuts against the latch and applies a force towards the locking groove to the latch.

[0044] With such a setting, the water tank assembly realizes detachable connection with the floor brush main body through the mutual insertion and cooperation of the latch and the locking groove, thereby facilitating the replenishment of cleaning water and cleaning liquid into the water tank assembly and facilitating the cleaning of the water tank assembly. At the same time, the third elastic member can prevent the latch from falling off the locking groove, ensuring the connection stability between the water tank assembly and the floor brush main body.

[0072] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application.

[0073] First of all, those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present application and are not intended to limit the protection scope of the present application. Those skilled in the art can adjust it as needed to adapt to specific application scenarios.

[0074] Secondly, it should be noted that in the description of the present application, terms such as "inner", "outer", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present application.

[0075] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0076] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present disclosure. In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0077] With the continuous development of technology and the improvement of people's living standards, more and more new household appliances such as floor washers have emerged in people's lives.

[0078] In the related art, cleaning devices such as floor washers include a floor brush device. The floor brush device includes a water tank, a rolling brush, and a water pump. The water pump is used to pump the cleaning water in the water tank to the rolling brush to wet the rolling brush, so as to improve the effect of the rolling brush cleaning the ground or for the self-cleaning of the rolling brush. However, in the related art, the cleaning water in the cleaning device is difficult to clean some surfaces to be cleaned with stubborn stains such as oil stains. Therefore, the cleaning effect can be improved by adding a cleaning solution to the cleaning water. Currently, generally, the method of manually mixing the cleaning solution into the cleaning water is adopted, or the method of pumping liquids from two containers containing the cleaning solution and the cleaning water respectively through the water pump and mixing them is adopted.

[0079] However, if the cleaning solution is manually added to the cleaning water, it is difficult to control the mixing ratio, and the concentration of the cleaning solution in the resulting mixed liquid cannot be controlled, resulting in a poor cleaning effect of the cleaning device. And if the method of pumping the cleaning solution and the cleaning water respectively through the water pump and mixing them is adopted, then an additional pipeline will be added, increasing the structural complexity. At the same time, since the cleaning solution is corrosive, it will cause corrosion to the pipeline and the water pump, thereby reducing the service life of the cleaning device.

[0080] To solve the above problems, in the floor brush device provided in the embodiments of the present application, a fresh water chamber and a cleaning liquid chamber are designed in the water tank assembly. The cleaning liquid chamber has a liquid outlet communicating with the fresh water chamber. The cleaning liquid chamber is used to hold the cleaning liquid, and the cleaning liquid in the cleaning liquid chamber is added to the fresh water chamber through the liquid outlet, so that the cleaning liquid is mixed and diluted with the cleaning water in the fresh water tank and then supplied to the cleaning member through the fresh water outlet. In this way, the cleaning effect of the cleaning member when cleaning the floor and self-cleaning can be improved; in addition, by arranging the liquid outlet on the side of the cleaning liquid chamber facing the fresh water outlet, the cleaning liquid is mixed and diluted with the cleaning water at a position close to the fresh water outlet, so as to reduce the area covered by the cleaning liquid in the fresh water chamber, thereby reducing the corrosion of the cleaning liquid on the water tank assembly, and further ensuring the service life of the water tank assembly.

[0081] In order to make the above objects, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0082] Please refer to Figure 1 As shown, the embodiments of the present application provide a floor brush device 10, including: a floor brush main body 100, a cleaning member 200 and a water tank assembly 300. The cleaning member 200 is connected to the floor brush main body 100, and the water tank assembly 300 is arranged on the floor brush main body 100. As Figures 2 - 5 shown, the water tank assembly 300 has a fresh water chamber 310 and a cleaning liquid chamber 320. The cleaning liquid chamber 320 has a liquid outlet 321 communicating with the fresh water chamber 310. The cleaning liquid chamber 320 is configured to add the cleaning liquid to the fresh water chamber 310 through the liquid outlet 321; the fresh water chamber 310 has a fresh water outlet 311, and the fresh water chamber 310 is configured to supply the cleaning water to the cleaning member 200 through the fresh water outlet 311.

[0083] In the embodiments of the present application, the fresh water chamber 310 is used to store the cleaning water. The fresh water chamber 310 has a fresh water outlet 311, and the fresh water chamber 310 is configured to supply the cleaning water to the cleaning member 200 through the fresh water outlet 311. Exemplarily, the fresh water outlet 311 can be directly aligned with the cleaning member 200 to supply the cleaning water to the cleaning member 200, or the fresh water outlet 311 can be connected by a pipeline to supply the cleaning water to the cleaning member 200 in a spraying, pipeline conveying or other ways.

[0084] The cleaning liquid chamber 320 and the clean water chamber 310 are two independent and separated chambers. The cleaning liquid chamber 320 is used to store the cleaning liquid, and the cleaning liquid chamber 320 has a liquid outlet 321. The cleaning liquid chamber 320 is configured to supply the cleaning liquid to the clean water chamber 310 through the liquid outlet 321, so as to mix the cleaning liquid and the cleaning water in the clean water chamber 310, and finally form the cleaning water containing the cleaning liquid.

[0085] Exemplarily, the liquid outlet 321 can be set to communicate with the top wall, bottom wall, side wall, etc. of the clean water chamber 310. After the cleaning water containing the cleaning liquid flows out from the clean water outlet 311, it can be supplied to the cleaning member 200. Exemplarily, the cleaning liquid can be a liquid with a stain-removing function such as a detergent. Among them, the cleaning liquid chamber 320 can be arranged side by side with the clean water chamber 310, or the cleaning liquid chamber 320 can be wholly placed in the clean water chamber 310, as long as the airtight separation between the two is ensured. At the same time, the liquid outlet 321 and the clean water outlet 311 can be respectively opened or closed to meet different cleaning requirements.

[0086] Among them, the cleaning member 200 includes but is not limited to a rotary brush, a cleaning cotton, a cleaning strip, etc., as long as it can be used to clean the ground. Hereinafter, the cleaning member 200 being a rotary brush will be taken as an example for introduction.

[0087] When the cleaning device is cleaning the ground, as the cleaning device moves along the forward direction, the cleaning member 200 can move relative to the ground (for example, rotate relative to the ground). The clean water chamber 310 supplies the cleaning water or the cleaning water containing the cleaning liquid to the cleaning member 200 through the clean water outlet 311 to humidify the cleaning member 200. Further, the cleaning member 200 infiltrated with the cleaning water containing the cleaning liquid wipes the ground during the movement relative to the ground, so as to achieve the purpose of cleaning the ground, and the cleaning liquid and the cleaning water sprayed onto the cleaning member 200 can improve the cleaning effect of the cleaning member 200 to remove stronger stains on the ground.

[0088] In addition, the liquid outlet 321 is located on the side of the cleaning liquid chamber 320 facing the clean water outlet 311. Exemplarily, if the clean water outlet 311 is located on the side wall of the clean water chamber 310 and the cleaning liquid chamber 320 is located inside the clean water chamber 310, then the liquid outlet 321 can be set on the side wall of the cleaning liquid chamber 320 facing the clean water outlet 311, so that the shortest straight-line distance is provided between the clean water outlet 311 and the liquid outlet 321.

[0089] Furthermore, the distance between the liquid outlet 321 and the clean water outlet 311 is relatively short. After the cleaning liquid flows out from the liquid outlet 321, it can quickly reach the clean water outlet 311, so as to be mixed and diluted with the cleaning water at a position close to the clean water outlet 311, and quickly discharged from the clean water outlet 311 after being mixed and diluted. Furthermore, the area covered by the cleaning liquid in the clean water chamber 310 can be effectively reduced, preventing the cleaning liquid from corroding the inner wall of the clean water chamber 310 and prolonging the service life of the water tank assembly 300.

[0090] In some embodiments, please refer to Figures 2 to 5 As shown, the clean water outlet 311 is located at the bottom wall of the clean water chamber 310, and the liquid outlet 321 is arranged facing the bottom wall of the clean water chamber 310.

[0091] The clean water outlet 311 is opened on the bottom wall of the clean water chamber 310, and the cleaning water can flow out from the clean water outlet 311 under the influence of gravity. At the same time, the liquid outlet 321 also faces the bottom wall of the clean water chamber 310. After the cleaning liquid flows into the clean water chamber 310 from the liquid outlet 321, it will also be affected by gravity and quickly mix with the cleaning water and quickly flow out from the clean water outlet 311. Furthermore, the residue of the cleaning liquid in the clean water chamber 310 can be effectively reduced, thereby further reducing the corrosion of the cleaning liquid on the water tank, and further ensuring the service life of the clean water tank 360.

[0092] Among them, the liquid outlet 321 and the clean water chamber 310 can be arranged opposite to each other to further improve the mixing and dilution efficiency.

[0093] In some embodiments, as Figure 4 and Figure 5 shown, the clean water outlet 311 is provided with a water outlet valve 312, and the liquid outlet 321 is located on the side of the water outlet valve 312.

[0094] The water outlet valve 312 is a structure that can be opened and closed connected to the clean water outlet 311. When the water outlet valve 312 is in the open state, the cleaning water mixed with the cleaning liquid or pure cleaning water can flow out from the clean water outlet 311. When the water outlet valve 312 is in the closed state, the liquid in the clean water chamber 310 cannot flow out from the clean water outlet 311, which is suitable for the situation where it is necessary to supplement the cleaning water into the clean water chamber 310. With such a setting, the water outlet valve 312 can control the inflow and outflow of water at the clean water outlet 311, and the liquid outlet 321 is arranged on the side of the water outlet valve 312, so that the cleaning liquid can be quickly mixed and diluted with the cleaning water at a position close to the water outlet valve 312 after flowing out from the liquid outlet 321, and quickly flow out from the water outlet valve 312 after dilution, further reducing the corrosion of the cleaning liquid on the clean water chamber 310.

[0095] Exemplarily, the water outlet valve 312 can be located inside the clean water chamber 310 and block the clean water outlet 311. When the water outlet valve 312 is in the open state, the water outlet valve 312 can move towards the inside of the clean water chamber 310, thereby exposing the clean water outlet 311. At this time, the liquid outlet 321 located on the side of the water outlet valve 312 can quickly flow towards the vicinity of the clean water outlet 311 with the cleaning liquid.

[0096] In some embodiments, as Figure 4 shown, the water outlet valve 312 includes a valve body 3121, a valve core 3122, and a first elastic member 3123. The valve body 3121 is connected to the inner wall of the clean water chamber 310 and is opposite to the clean water outlet 311. The side wall of the valve body 3121 has a water inlet hole 31211.

[0097] The valve body 3121 is fixedly connected inside the clean water chamber 310, and the valve body 3121 has a certain length, protruding a certain distance from the clean water outlet 311 towards the inside of the clean water chamber 310 as a whole. The inside of the valve body 3121 has a cavity, and one or more water inlet holes 31211 are provided on the side wall of the valve body 3121. The liquid in the clean water chamber 310 can enter the cavity in the valve body 3121 through the water inlet hole 31211.

[0098] In addition, the valve core 3122 is movably arranged inside the valve body 3121 to enable the valve core 3122 to close or open at least one of the clean water outlet 311 and the water inlet hole 31211; the first elastic member 3123 abuts against the valve core 3122, and the first elastic member 3123 is configured to apply a force towards the clean water outlet 311 to the valve core 3122.

[0099] The valve core 3122 is movably arranged in the cavity of the valve body 3121 and can move along the cavity to realize the blocking or opening of the clean water outlet 311. The first elastic member 3123 is a structure with elasticity and can perform elastic expansion and contraction. When the valve core 3122 is in the open state of the clean water outlet 311, the first elastic member 3123 can be in a compressed state or a natural state. At this time, the valve core 3122 can be set to block the clean water outlet 311 or the water inlet hole 31211, or block both at the same time.

[0100] As Figure 4As shown, the valve core 3122 is arranged to block the clean water outlet 311, and there is a gap between the valve core 3122 and the water inlet hole 31211 without blocking the water inlet hole 31211; when the valve core 3122 moves in a direction away from the clean water outlet 311, the first elastic member 3123 is compressed to a greater extent. At this time, the clean water outlet 311 is opened, and the liquid in the clean water chamber 310 can flow into the cavity of the valve body 3121 through the water inlet hole 31211 and finally flow out of the clean water chamber 310 through the clean water outlet 311. Alternatively, the water inlet hole 31211 can also be arranged near the clean water outlet 311. When the valve core 3122 moves in a direction away from the clean water outlet 311, the water inlet hole 31211 and the clean water outlet 311 are simultaneously opened, so that the liquid in the clean water chamber 310 can flow into the cavity of the valve body 3121 through the water inlet hole 31211 and finally flow out of the clean water chamber 310 through the clean water outlet 311.

[0101] In this way, when water is not needed, for example, when the water tank assembly 300 is removed from the floor brush main body 100, the valve core 3122 can be pressed against the clean water outlet 311 by the acting force of the first elastic member 3123 to block the clean water outlet 311 and prevent water leakage. When water is needed, for example, when the water tank assembly 300 is installed on the floor brush main body 100, a raised lifting member can be arranged in the floor brush main body 100. The lifting member can abut against one end of the valve core 3122 that faces away from the clean water chamber 310 and blocks the clean water outlet 311, and apply an external acting force to the valve core 3122, so that the valve core 3122 is lifted into the interior of the clean water chamber 310 by a certain distance, thereby opening the clean water outlet 311. The water in the clean water chamber 310 flows out of the clean water chamber 310 through the water inlet opened on the valve body 3121 and flows out from the clean water outlet 311 to achieve the cleaning purpose.

[0102] It can be understood that when the water tank assembly 300 is removed, the first elastic member 3123 will automatically reset, driving the valve core 3122 to block at least one of the clean water outlet 311 and the water inlet hole 31211 again.

[0103] In some embodiments, as Figure 5 shown, the liquid outlet 321 is provided with a fixing portion 3211 protruding into the clean water chamber 310; the water tank assembly 300 further includes a first one-way valve 330. The first one-way valve 330 is sleeved outside the fixing portion 3211, and the liquid outlet 321 is in one-way communication with the clean water chamber 310 through the first one-way valve 330.

[0104] The fixing part 3211 surrounds the side of the liquid outlet 321 completely or partially, so that the first one-way valve 330 can be stably sleeved outside the fixing part 3211. The first one-way valve 330 only allows liquid to pass through unidirectionally. Furthermore, the liquid outlet 321 can unidirectionally transport to the clean water chamber 310 through the first one-way valve 330, preventing the backflow of the cleaning water into the cleaning liquid chamber 320, ensuring the self-concentration of the cleaning liquid in the cleaning liquid chamber 320, avoiding the waste of the cleaning liquid and affecting the subsequent cleaning effect.

[0105] Wherein, the outlet of the first one-way valve 330 can face the clean water outlet 311, so that after the cleaning liquid flows out from the outlet of the first one-way valve 330, it can be directly mixed and diluted with the cleaning water near the clean water outlet 311, thereby further preventing the corrosion of the inner wall of the clean water chamber 310 by the cleaning liquid.

[0106] In some embodiments, as Figure 4 and Figure 5 shown, an installation groove 340 is provided at the top of the cleaning liquid chamber 320, and a through hole 341 communicating the inside and the outside of the cleaning liquid chamber 320 is provided in the installation groove 340; a pressing component 350 is provided in the installation groove 340, and the pressing component 350 is configured to press the cleaning liquid in the cleaning liquid chamber 320 into the clean water chamber 310.

[0107] The installation groove 340 is recessed at the top of the cleaning liquid chamber 320, and the pressing component 350 is movably arranged in the installation groove 340. The pressing component 350 can move along the direction close to or away from the inside of the cleaning liquid chamber 320, and at least part of the pressing component 350 can extend into the through hole 341 and be located inside the cleaning liquid chamber 320. When the user presses the pressing component 350, the pressing component 350 moves towards the inside of the cleaning liquid chamber 320, at least part of the pressing component 350 enters the cleaning liquid chamber 320 through the through hole 341, and squeezes the cleaning liquid in the cleaning liquid chamber 320 to squeeze out the cleaning liquid from the liquid outlet 321.

[0108] Among them, a reset structure, such as a pneumatic rod structure, can be set in the pressing component 350 to realize the automatic reset of the pressing component 350 after one pressing, which is convenient for the next pressing.

[0109] In this way, the user can press a fixed amount of cleaning liquid into the clean water chamber 310 through the pressing component 350 located at the top of the cleaning liquid chamber 320, realize the addition of the cleaning liquid as needed, prevent the addition of too much cleaning liquid, and the operation is fast, improving the cleaning efficiency. At the same time, the pressing component 350 is arranged in the installation groove 340, which also ensures the structural integrity of the water tank assembly 300.

[0110] Among them, the end face of the pressing assembly 350 facing away from the cleaning liquid chamber 320 can be set to protrude a certain distance from the outer surface of the cleaning liquid chamber 320, so as to facilitate the user's pressing.

[0111] In some embodiments, as Figure 5 shown, the pressing assembly 350 includes a pressing member 351, a fixing bracket 352, a second elastic member 353, and a first sealing member 354; the pressing member 351 is connected to the fixing bracket 352; at least part of the fixing bracket 352 is inserted into the through hole 341; the first sealing member 354 is sleeved on the outside of the fixing bracket 352 and abuts against the inner wall of the through hole 341; the second elastic member 353 abuts between the bottom wall of the mounting groove 340 and the fixing bracket 352, and the second elastic member 353 is configured to apply a force towards the outside of the mounting groove 340 to the fixing bracket.

[0112] The fixing bracket 352 is movably arranged in the mounting groove 340, and the fixing bracket 352 can move closer to or away from the inside of the cleaning liquid chamber 320 together with the pressing member 351. At least part of the fixing bracket 352 is inserted into the through hole 341, and the fixing member and the through hole 341 are sealed by the first sealing member 354. The second elastic member 353 is a structure that can elastically expand and contract, such as a spring. The pressing member 351 is located at one end of the pressing assembly 350 facing away from the cleaning liquid chamber 320 for the user to press. When the pressing member 351 is not pressed, it is subjected to the elastic force of the second elastic member 353 in the direction away from the cleaning liquid chamber 320 for the user to press.

[0113] When the user presses the pressing assembly 350, the fixing member will also be subjected to a pushing force and then move towards the inside of the cleaning liquid chamber 320. At this time, the second elastic member 353 is compressed. Since the first sealing member 354 seals the through hole 341, the cleaning liquid will not leak from the through hole 341 into the mounting groove 340. The fixing member moves towards the inside of the mounting groove 340, thereby squeezing the internal space of the cleaning liquid chamber 320, forcing the cleaning liquid to flow from the liquid outlet 321 into the clear water chamber 310, realizing rapid and stable addition of the cleaning liquid.

[0114] It can be understood that after one pressing, the second elastic member will drive the pressing member 351 to reset, so that the user can intermittently press the pressing member 351 multiple times to realize multiple quantitative additions of the cleaning liquid.

[0115] In some embodiments, as Figure 5 shown, the pressing assembly 350 further includes a second one-way valve 355. The second one-way valve 355 is connected to the fixing bracket 352. The pressing member 351 is provided with an air inlet hole 3511. The air inlet hole 3511 is opposite to the air inlet end of the second one-way valve 355. The second one-way valve 355 is configured to make the air inlet hole 3511 communicate with the through hole 341 unidirectionally.

[0116] The second one-way valve 355 allows air to flow unidirectionally, with the flow direction being from the outside of the cleaning liquid chamber 320 to the inside of the cleaning liquid chamber 320. At the same time, the air inlet hole 3511 on the pressing member 351, the second one-way valve 355, and the through hole 341 are sequentially connected. When the cleaning liquid chamber 320 is not full, after the user presses the pressing member 351 once, the volume inside the cleaning liquid chamber 320 is compressed, and there may be a situation where the internal air pressure of the cleaning liquid chamber 320 is less than the external air pressure, resulting in the pressing member 351 being unable to reset.

[0117] In specific implementation, by setting the air inlet hole 3511 and the second one-way valve 355, when the user completes one press, air can enter the second one-way valve 355 through the air inlet hole 3511, then enter the through hole 341 from the one-way valve, and finally enter the cleaning liquid chamber 320, achieving the balance of the internal and external air pressures of the cleaning liquid chamber 320 and enabling the pressing member 351 to reset smoothly. At the same time, the second one-way valve 355 can prevent the cleaning liquid from gushing out from the through hole 341.

[0118] It can be understood that at this time, an air passage can be opened on the fixing bracket 352, and the air passage penetrates through the through hole 341, enabling gas to flow from the second one-way valve 355 into the inside of the cleaning liquid chamber 320, while the cleaning liquid flowing back in the air passage will be blocked by the second one-way valve 355.

[0119] With such a setting, when the pressing member 351 is pressed and the internal and external air pressures of the cleaning liquid chamber 320 are unbalanced and it cannot reset, the air in the cleaning liquid chamber 320 will successively enter the inside of the cleaning liquid chamber 320 through the air inlet hole 3511, the second one-way valve 355, and the through hole 341, achieving the balance of the internal and external air pressures and enabling the pressing member 351 to reset smoothly.

[0120] In some embodiments, please refer to Figure 2 and Figure 6 , Figure 6 which is the third disassembled structural schematic diagram of the water tank assembly 300 in the floor brush device 10 provided by the embodiment of the present application. As Figure 2 and Figure 6 shown, a water filling port 313 is provided at the top of the clean water chamber 310, and a first sealing plug 314 is provided at the water filling port 313, and the first sealing plug 314 is sealingly connected to the water filling port 313; and / or, a liquid filling port 322 is provided at the top of the cleaning liquid chamber 320, and a second sealing plug 323 is provided at the liquid filling port 322, and the second sealing plug 323 is sealingly connected to the liquid filling port 322.

[0121] The first sealing plug 314 is detachably connected to the water filling port 313, and the second sealing plug 323 is detachably connected to the liquid filling port 322. After the user opens the first sealing plug 314, cleaning water can be quickly replenished into the interior of the clean water chamber 310 through the water filling port 313, and after the replenishment is completed, the first sealing plug 314 is used to prevent the leakage of the cleaning water. After the second sealing plug 323 is opened, cleaning liquid can be quickly replenished into the interior of the cleaning liquid chamber 320 through the liquid filling port 322, and after the replenishment is completed, the second sealing plug 323 is used to prevent the leakage of the cleaning liquid. Furthermore, the quick separate replenishment of the cleaning water and the cleaning liquid is realized.

[0122] In some embodiments, please refer to Figure 2 and Figure 7 , Figure 7 which is the schematic diagram of the fourth disassembled structure of the floor brush device 10 provided by the embodiment of the present application. As Figure 2 and Figure 7 shown, the water tank assembly 300 includes a clean water tank 360, and the clean water tank 360 has an independent clean water chamber 310 and a cleaning liquid chamber 320.

[0123] The clean water chamber 310 and the cleaning liquid chamber 320 are two independent chambers in the clean water tank 360. The clean water chamber 310 and the cleaning liquid chamber 320 are independent of each other and are located in the overall clean water tank 360, ensuring the integrity of the structure. At the same time, the clean water chamber 310 and the cleaning liquid chamber 320 are independent of each other, and can store a certain amount of cleaning water and cleaning liquid respectively, and can prevent the cleaning water and the cleaning liquid from being mixed in advance, further preventing the corrosion of the clean water chamber 310 by the cleaning liquid and improving the service life.

[0124] In some embodiments, please refer to Figure 2 , Figure 7 and Figure 8 , the clean water tank 360 includes a first housing 361, a second housing 362 and a third housing 363. The first housing 361 and the second housing 362 are connected and jointly enclose to form the clean water chamber 310; the third housing 363 is disposed in the clean water chamber 310, and the third housing 363 encloses to form the cleaning liquid chamber 320; or, the third housing 363 is connected to one of the first housing 361 and the second housing 362 and jointly encloses to form the cleaning liquid chamber 320.

[0125] The third housing 363 is located in the clear water chamber 310 formed by the common enclosure of the first housing 361 and the second housing 362, and the third housing 363 itself can enclose to form a closed cleaning liquid chamber 320; alternatively, one end face of the third housing 363 is an open end face, and this open end face is attached to the first housing 361 or the second housing 362 to form an independent cleaning liquid chamber 320. The third housing 363 is located in the clear water chamber 310, and the formed cleaning liquid chamber 320 is also entirely located in the clear water chamber 310, further reducing the distance between the liquid outlet 321 and the clear water outlet 311 of the clear water chamber 310, improving the addition efficiency of the cleaning liquid to the cleaning water, and further reducing the contact time of the cleaning liquid with the clear water chamber 310, preventing the corrosion of the clear water chamber 310. Among them, the first housing 361, the second housing 362 and the third housing 363 can be detachably connected to each other to achieve rapid disassembly and cleaning.

[0126] In some embodiments, such as Figure 2 , Figure 5 and Figure 7 shown, the third housing 363 encloses to form a cleaning liquid chamber 320, and the third housing 363 is detachably connected to the clear water tank 360.

[0127] The third housing 363 has a detachable connection with one or both of the first housing 361 and the second housing 362, specifically, it can be a plug connection or a snap connection, etc. The liquid outlet 321 is opened on the third housing 363, and the third housing 363 is a fully enclosed structure. With such a setting, the third housing 363, as a separate detachable part, the cleaning liquid chamber 320 enclosed by it can be detached from the clear water tank 360, and then the cleaning member 200 can be supplied and cleaned with only cleaning water to cope with the situation where the cleaning liquid is not applicable. At the same time, the cleaning liquid chamber 320 can be quickly cleaned after the third housing 363 is detached.

[0128] In some embodiments, such as Figure 2 , Figure 5 and Figure 7 shown, the third housing 363 is connected to one of the first housing 361 and the second housing 362 and jointly encloses to form a cleaning liquid chamber 320, and a first positioning portion 364 is provided on the circumferential edge of the third housing 363, and a second positioning portion 365 is provided on one of the first housing 361 and the second housing 362; at least a part of the first positioning portion 364 is hermetically connected to the second positioning portion 365.

[0129] The first positioning portion 364 and the second positioning portion 365 are used to determine the installation position and direction of the third housing 363, so as to prevent the open end face in the third housing 363 from enclosing with the wrong housing among the first housing 361 and the second housing 362, and avoid leakage caused by loose enclosure. When it is necessary to add cleaning liquid for cleaning, the third housing 363 can be quickly connected and sealed with the second positioning portion 365 in the first housing 361 or the second housing 362 through the first positioning portion 364, so as to quickly form a sealed cleaning liquid cavity 320, meeting the usage requirements.

[0130] In some embodiments, the first positioning portion 364 is one of a positioning groove and a positioning rib, the second positioning portion 365 is the other of the positioning groove and the positioning rib, and at least part of the positioning rib is inserted into the positioning groove.

[0131] The positioning rib is a structure protruding on the first housing 361, the second housing 362 or the third housing 363, while the positioning groove is a structure recessed on the first housing 361, the second housing 362 or the third housing 363.

[0132] Exemplarily, as Figure 5 shown, the first positioning portion 364 can be set as a positioning rib, the second positioning portion 365 on the first housing 361 can be set as a positioning groove, and the positioning rib is inserted into the positioning groove. Furthermore, quick alignment connection can be achieved between the third housing 363 and the first housing 361 or the second housing 362. While improving the assembly efficiency, the sealing performance of the cleaning liquid cavity 320 is ensured.

[0133] In some embodiments, the wall of the cleaning liquid cavity 320 has an anti-corrosion layer. The anti-corrosion layer can be a structure separately installed on the cleaning liquid cavity 320 or a plating structure. The anti-corrosion layer is made of anti-corrosion material. Thus, the anti-corrosion layer can prevent the wall of the cleaning liquid cavity 320 from being corroded by the cleaning liquid, and the service life of the cleaning liquid cavity 320 is prolonged.

[0134] In some embodiments, please refer to Figure 2 、 Figures 9 - 13 , Figure 9 is a schematic structural diagram of the water tank assembly 300 in the floor scrubbing device 10 provided by the embodiment of the present application; Figure 10 is a schematic structural diagram of the floor scrubbing main body 100 in the floor scrubbing device 10 provided by the embodiment of the present application; Figure 11 is a schematic disassembled structural diagram of the floor scrubbing main body 100 in the floor scrubbing device 10 provided by the embodiment of the present application; Figure 12 is a schematic sectional structural diagram of the floor scrubbing device 10 provided by the embodiment of the present application; Figure 13 is another schematic sectional structural diagram of the floor scrubbing device 10 provided by the embodiment of the present application. As Figure 2 、Figures 9 - 13 As shown, the floor brush device 10 further includes a water pump 400 and a water spraying assembly 500. The water pump 400 is disposed on the floor brush main body 100, and the water spraying assembly 500 is connected to the water tank assembly 300. The water inlet of the water pump 400 is communicated with the clean water outlet 311, and the water outlet of the water pump 400 is communicated with the water inlet of the water spraying assembly 500. The water spraying assembly 500 has water spraying holes 510 facing the cleaning member 200.

[0135] The water inlet of the water pump 400 can suck the liquid flowing out from the clean water outlet 311, then pump it into the water spraying assembly 500, and finally spray the liquid onto the cleaning member 200 through the water spraying holes 510 opened in the water spraying assembly 500 to realize the wetting of the cleaning member 200.

[0136] Exemplarily, as Figures 11 - 13 shown, a first pipeline 420 and a second pipeline 430 can be respectively connected to the water inlet and the water outlet of the water pump 400. The water inlet of the water pump 400 is communicated with the clean water outlet 311 through the first pipeline 420, and the clean water outlet 311 of the water pump 400 is communicated with the water inlet of the water spraying assembly 500 through the second pipeline 430. The water inlet of the water spraying assembly 500 is communicated with the water spraying holes 510. Further, the water pump 400 can suck the cleaning water mixed with the cleaning liquid from the clean water outlet 311 and supply the liquid to the cleaning member 200 through the water spraying holes 510 of the water spraying assembly 500, so that the cleaning member 200 is kept wet and the cleaning effect is improved.

[0137] It can be understood that the water pump 400 directly sucks the cleaning water mixed with the cleaning liquid, without separately sucking the cleaning liquid and the cleaning water and then mixing them, which eliminates excessive pipelines, reduces the structural complexity, and improves the liquid supply efficiency to the cleaning member 200. Among them, the water spraying holes 510 can be one or more. If there are multiple water spraying holes 510, the multiple water spraying holes 510 can be arranged at intervals side by side to supply liquid to the cleaning member 200 evenly.

[0138] Among them, the structure of the water pump 400 can refer to the related art and will not be elaborated here.

[0139] In some embodiments, as Figures 11 - 13 shown, a second seal 315 is provided at the clean water outlet 311, and the second seal 315 abuts against the inner wall of the water inlet of the water pump 400; and / or, a third seal 410 is provided at the water outlet of the water pump 400, and the third seal 410 abuts against the inner wall of the water inlet of the water spraying assembly 500. The second seal 315 and the third seal 410 can be made of materials conducive to sealing, such as silicone.

[0140] Exemplarily, a protrusion may be provided protruding around the water outlet 311 of the clean water. The protrusion partially or completely surrounds the periphery of the clean water outlet 311, and the second seal 315 is sleeved outside the protrusion. One end of the first pipe 420 is sleeved outside the second seal 315 to achieve the seal between the water inlet of the water pump 400 and the clean water outlet 311. One end of the third seal 410 extends into the water inlet of the water spraying assembly 500 and fits against the inner wall of the water inlet of the water spraying assembly 500, and the second pipe 430 is sleeved on one end of the third seal 410 located outside the water inlet of the water spraying assembly 500 to achieve the seal between the water outlet of the water pump 400 and the water inlet of the water spraying assembly 500.

[0141] In this way, the second seal 315 enables the cleaning water mixed with the cleaning liquid flowing out of the clean water outlet 311 to smoothly enter the water inlet of the water pump 400 without leakage. The third seal 410 can prevent the cleaning water mixed with the cleaning liquid from leaking from the water outlet of the water pump 400, ensuring the efficient delivery of the cleaning water mixed with the cleaning liquid to the water spraying assembly 500.

[0142] In some embodiments, as Figure 9 and Figure 12 shown, the floor brush device 10 further includes a squeegee 600. The squeegee 600 is connected to the outer wall of the water tank assembly 300, and the squeegee 600 abuts against the cleaning member 200.

[0143] Exemplarily, the squeegee 600 can be installed on the end face of the water tank assembly 300 facing the cleaning member 200, and the extension axis of the squeegee 600 is parallel to the extension axis of the cleaning member 200. Exemplarily, the cleaning member 200 is rotatably connected to the floor brush main body 100, and the rotation axis of the cleaning member 200 is parallel to the extension axis of the squeegee 600. The squeegee 600 fits against the side wall of the cleaning member 200.

[0144] When the cleaning member 200 rotates while rubbing on the ground, the squeegee 600 can scrape off the sundries adhered to the cleaning member 200, and can scrape out the cleaning water mixed with the cleaning liquid infiltrated on the cleaning member 200 to the surface to be cleaned, or evenly scrape the cleaning water mixed with the cleaning liquid to various positions on the side wall of the cleaning member 200, thereby improving the cleaning effect.

[0145] In some embodiments, as Figure 2 , Figure 9 and Figure 10As shown, a latch 370 and a third elastic member 380 are provided outside the water tank assembly 300. The latch 370 is movably connected to the water tank assembly 300. A locking groove 110 is provided on the main body 100 of the floor brush. The latch 370 can be inserted into the locking groove 110 or disengaged from the locking groove 110; the third elastic member 380 abuts against the latch 370 and applies a force to the latch 370 towards the locking groove 110.

[0146] The third elastic member 380 is disposed between the latch 370 and the water tank assembly 300, and the locking groove 110 is recessed on the main body 100 of the floor brush. When the user needs to connect the water tank assembly 300 to the main body 100 of the floor brush, the latch 370 can be pressed towards the water tank assembly 300 by a certain distance, and then the latch 370 is snapped into the locking groove 110. At this time, the third elastic member 380 will push the latch 370 to reset and be inserted into the locking groove 110.

[0147] It can be understood that the water tank assembly 300 realizes a detachable connection with the main body 100 of the floor brush through the mutual insertion and cooperation of the latch 370 and the locking groove 110, thereby facilitating the replenishment of cleaning water and cleaning liquid into the water tank assembly 300 and facilitating the cleaning of the water tank assembly 300. At the same time, the third elastic member 380 can prevent the latch 370 from falling out of the locking groove 110, ensuring the connection stability between the water tank assembly 300 and the main body 100 of the floor brush.
