Description

Technical Field

[0001] This application relates to the field of cleaning technology, specifically to a cleaning device and a cleaning system. Background Technology

[0002] Cleaning equipment, such as floor scrubbers, is a type of cleaning machinery suitable for cleaning surfaces like floors and carpets. It simultaneously vacuums up solid and liquid debris from the surfaces and pumps the dirt into a wastewater tank for removal from the site. Floor scrubbers integrate cleaning, vacuuming, and drying, offering advantages such as environmental friendliness, energy efficiency, and high performance.

[0003] In related technologies, a wastewater tank is used to pump out solid and liquid waste from the surface to be cleaned. After cleaning, the user disposes of the solid and liquid waste in the wastewater tank. However, during the cleaning process, as the wastewater tank continuously pumps out solid and liquid waste from the surface, its weight increases, leading to increased hand strength required from the user to operate the floor scrubber. This makes operating the floor scrubber more strenuous and negatively impacts the user experience. Utility Model Content

[0004] This application provides a cleaning device and a cleaning system that can solve the problem of excessive hand force during the cleaning process, which affects the user experience.

[0005] In a first aspect, this application provides a cleaning device, comprising:

[0006] A floor brush assembly for cleaning surfaces to be cleaned;

[0007] The body is connected to the floor brush assembly;

[0008] Wastewater tank, the wastewater tank comprising:

[0009] A first housing, disposed on the machine body, is used to receive solids and liquids recovered from the surface to be cleaned;

[0010] The second housing is a separate structure from the first housing. The second housing is disposed on the floor brush assembly and is connected to the first housing. The second housing is used to partially receive the liquid in the first housing.

[0011] The solid remains in the first container, while the liquid enters the second container.

[0012] The cleaning equipment provided in this application is readily understood to have a situation where the weight of the liquid generated during the cleaning process is typically much greater than the weight of the solids. Therefore, the weight of the second chamber is usually greater than the weight of the first chamber. Furthermore, since the first chamber is located within the main body and the second chamber is located within the floor brush assembly, the height of the main body is typically higher than the height of the floor brush assembly during cleaning. Therefore, by placing the heavier second chamber within the relatively lower-positioned floor brush assembly, the weight of the main body can be reduced, and the center of gravity of the main body can be lowered.

[0013] During the cleaning process, the user holds the device by its grip to operate it and clean the surface to be cleaned. When the liquid in the first chamber flows into the second chamber, the first chamber retains solids and a small amount of liquid, reducing the device's weight and lowering its center of gravity. This reduces the force exerted on the device and the lever arm of gravity relative to the rotation point of the floor brush assembly. Therefore, it effectively reduces the force required by the user to hold the device, achieving a more labor-saving effect and improving the user experience.

[0014] Specifically, during the cleaning process, the cleaning equipment maintains an angle of inclination between its body and the surface to be cleaned. The direction of the user's hand-held force is opposite to the direction of the equipment's weight. The product of the user's hand-held force and its lever arm is greater than or equal to the product of the equipment's weight and its lever arm. The flow of liquid from the first chamber into the second chamber reduces the weight within the first chamber, thus lightening the equipment's weight and lowering its center of gravity. Consequently, both the equipment's weight and its lever arm decrease, resulting in a significant reduction in their product. When the lever arm remains constant, this effectively reduces the user's hand-held effort, achieving a labor-saving effect.

[0015] Furthermore, since the liquid in the first chamber can enter the second chamber on the floor brush assembly, the gravity of the liquid can still act on the floor brush assembly to ensure the floor brush assembly's pressure on the ground, thereby ensuring the cleaning effect on the surface to be cleaned, especially for stubborn stains.

[0016] In addition, since the liquid in the first chamber can enter the second chamber, and a small amount of liquid remains in the first chamber, it is relatively easy to dry the first chamber, thereby reducing the possibility that dirt in the first chamber will remain in a humid environment for a long time, leading to the growth of bacteria or the generation of odors.

[0017] Since the first chamber is located on the main body and the second chamber is located on the floor brush assembly, the height of the first chamber relative to the surface to be cleaned is higher than the height of the second chamber relative to the surface to be cleaned. Therefore, the liquid in the first chamber can enter the second chamber under the action of gravitational potential energy.

[0018] It should be noted that in this embodiment, the first and second tanks are separate structures, therefore, the first and second tanks can be cleaned independently. Since the liquid in the first tank can flow into the second tank, the first tank is mainly used for storing solids, and the second tank is mainly used for storing liquids. This facilitates user sorting of contaminants, improving the cleaning efficiency of the wastewater tank. Furthermore, it reduces the possibility of solid and liquid mixtures clogging the drain pipes.

[0019] According to one embodiment of this application, the first box is provided with a drain port, which is used to transport the liquid in the first box to the second box, and the drain port is located at the lowest position of the first box.

[0020] In this embodiment, the liquid in the first tank can enter the second tank through the drain port. By positioning the drain port at the lowest point of the first tank, the liquid in the first tank can be drained more easily, which helps reduce the possibility of liquid remaining at the bottom or edge of the first tank.

[0021] According to one embodiment of this application, the first box has a bottom wall that is inclined, the drain outlet is disposed on the bottom wall and is located at the lowest point of the bottom wall, so that the drain outlet is located at the lowest position of the first box.

[0022] By sloping the bottom wall, it can guide the liquid in the first tank to the drain outlet, thereby improving drainage efficiency. Furthermore, since the drain outlet is located at the lowest point of the bottom wall, liquid at the lowest point can enter the second tank through the drain outlet, reducing the likelihood of liquid accumulating at the lowest point of the first tank.

[0023] It's easy to understand that having liquid inside the first chamber has two main problems. First, it increases the weight of the first chamber, affecting the overall lightweight design and thus reducing the effort required to hold the device. Second, it exacerbates the humidity level inside the first chamber, making it prone to bacterial growth and unpleasant odors. Furthermore, it hinders the drying process within the first chamber.

[0024] Furthermore, when the cleaning equipment is stationary or charging, the body can tilt forward relative to the brush assembly along the direction of travel to stabilize the equipment's center of gravity and prevent it from tipping over. The forward-tilting body also provides a certain amount of forward thrust to assist the user in pushing the cleaning equipment forward, reducing the burden on the user.

[0025] Therefore, by setting the bottom wall to be tilted, the possibility of liquid flowing back from the lowest position of the bottom wall to other directions can be reduced when the fuselage is tilted forward.

[0026] In some examples, along the forward direction of the cleaning equipment, the first housing may be located at the front of the machine or at the rear of the machine, and this is not limited in the embodiments of this application.

[0027] For example, taking the first housing as being located at the rear of the machine body, the bottom wall can be tilted downwards from front to back. Therefore, when the cleaning equipment is stationary or charging so that the machine body is tilted forward, the drain outlet can be ensured to be at the lowest position of the first housing. Thus, when the cleaning equipment is running and the machine body is tilted backwards, the drain outlet can still be kept at the lowest position of the first housing, thereby more effectively reducing the possibility of liquid accumulation in the first housing.

[0028] According to one embodiment of this application, a separator is further included, the separator being located in the first housing, the separator being used to separate the solid and the liquid in the first housing, so that the solid is retained in the first housing and the liquid passes through the separator to enter the second housing.

[0029] In this embodiment, the separator can be used to screen solids in the first chamber to retain them within the first chamber. This reduces the likelihood of solids entering the second chamber and affecting the solid-liquid separation effect. It also reduces the possibility of solids clogging the drain outlet and affecting the flow rate of liquid into the second chamber.

[0030] Specifically, solids can be screened to the top of the separator, while liquids can pass through the separator downwards and enter the second chamber through the drain port. In other words, solids can remain above the separator, thus preventing solids from easily entering between the separator and the bottom wall of the first chamber, reducing the possibility of solids clogging the drain port.

[0031] According to one embodiment of this application, the separator is located near the bottom wall of the first housing.

[0032] In this embodiment, the solids in the first chamber will settle downwards under the influence of gravity. By placing the separator close to the bottom wall, the amount of liquid contained between the separator and the bottom wall is reduced, which decreases the likelihood of liquid flowing within the first chamber and the liquid between the separator and the bottom wall carrying the solids upwards and mixing them in the liquid. This is beneficial for improving the separation efficiency and effect of solids and liquids.

[0033] Furthermore, when the liquid between the separator and the bottom wall causes the solids on the separator to resuspend, the solids will sink downwards again under the action of gravity. Moreover, the solids will cause secondary impact and wear on the separator under the action of liquid flow, which will affect the separation effect and service life of the separator.

[0034] According to one embodiment of this application, the first chamber has a first negative pressure environment for drawing the solid and liquid from the surface to be cleaned into the first chamber;

[0035] The second chamber has a second negative pressure environment, and the second chamber is in a negative pressure state relative to the first chamber;

[0036] When the second chamber is in the negative pressure state, the air pressure of the second negative pressure environment is less than the air pressure of the first negative pressure environment, so that the liquid in the first chamber is automatically drawn into the second chamber.

[0037] In this embodiment, when the second chamber is under negative pressure relative to the first chamber, it can provide the liquid in the first chamber with the power to flow to the second chamber. Under the influence of gravitational potential energy and the second negative pressure environment within the second chamber, the liquid in the first chamber can be rapidly drawn into the second chamber. This reduces the slow flow rate of the liquid from the first chamber to the second chamber, preventing the weight of the machine from being released and increasing the likelihood that the user will still exert significant force when holding the cleaning device.

[0038] The first negative pressure environment inside the first chamber can refer to the situation where the air pressure inside the first chamber is lower than the air pressure of the external environment (e.g., the surface to be cleaned), thus creating a first negative pressure environment relative to the external environment. The air pressure in the external environment and the air pressure inside the first chamber create a pressure difference, which allows solids and liquids on the surface to be cleaned to be automatically drawn into the first chamber under the action of the pressure difference.

[0039] The second negative pressure environment within the second chamber refers to a situation where the air pressure within the second chamber is lower than the air pressure within the first chamber, thus creating a second negative pressure environment relative to the first chamber. A pressure difference can be created between the air pressure within the first chamber and the air pressure within the second chamber. Under the influence of this pressure difference, solids and liquids within the first chamber can flow towards the drain port. Solids within the first chamber are blocked by the separator and remain within the first chamber, while liquids within the first chamber can be drawn into the second chamber through the separator.

[0040] According to one embodiment of this application, it further includes a first negative pressure device, which is disposed on the body and connected to the first housing, thereby creating the first negative pressure environment for the first housing.

[0041] In this embodiment of the application, the first negative pressure environment is connected to the first box. When the first negative pressure environment is running, air can be extracted from the first box to provide the first negative pressure environment for the first box.

[0042] Because the first and second housings are separate structures for storing solids and liquids respectively, and the second housing is located on the floor brush assembly, the first housing occupies less space within the machine body. The height of the first housing can be reduced, allowing the position of the first negative pressure device to also be lowered. Since the first negative pressure device has a certain weight, lowering its position lowers the machine's center of gravity, thus more effectively reducing the force exerted by the user on the cleaning equipment.

[0043] According to one embodiment of this application, the first negative pressure device is connected to the second box, the first negative pressure device provides the second box with a second negative pressure environment, and the first negative pressure device simultaneously draws air from the first box and the second box.

[0044] In this embodiment, the first negative pressure device can be used to provide a first negative pressure environment for the first chamber, and it can also be used to provide a second negative pressure environment for the second chamber. Therefore, a single first negative pressure device can simultaneously suction the first and second chambers, ensuring that the air pressure in the second negative pressure environment is lower than that in the first negative pressure environment. This eliminates the need for additional equipment on the cleaning device to create a second negative pressure environment for the second chamber, saving space and reducing the likelihood of increased weight and cost due to such additional equipment.

[0045] It should be noted that the first negative pressure device suctions the first chamber, creating a first negative pressure environment inside the first chamber. Furthermore, since the first chamber is connected to the external environment, it can draw solids and liquids from the surface to be cleaned into the first chamber, and outside air can enter the first chamber. Therefore, when the first negative pressure device simultaneously suctions the first and second chambers, the air pressure inside the first chamber can switch between the external air pressure and the air pressure under the first negative pressure environment. When the first negative pressure environment is established inside the first chamber, the air pressure inside the first chamber is lower than the external air pressure, thus drawing solids and liquids from the surface to be cleaned into the first chamber. When the air pressure inside the first chamber is close to the external air pressure, the air pressure inside the second chamber is lower than the air pressure inside the first chamber, so that the liquid in the first chamber is drawn into the second chamber under the effect of the pressure difference between the second and first chambers.

[0046] According to one embodiment of this application, the suction effect of the first negative pressure device on the first box is greater than the suction effect on the second box.

[0047] In this embodiment of the application, during the cleaning process, the cleaning equipment mainly relies on the air pressure inside the first chamber being lower than the air pressure of the external environment to achieve the suction of solids and liquids on the surface to be cleaned. Therefore, when the first negative pressure device simultaneously suctions the first chamber and the second chamber, by setting the suction effect of the first negative pressure device on the first chamber to be greater than that on the second chamber, the suction force on the surface to be cleaned can be guaranteed, thereby ensuring the cleaning effect on the surface to be cleaned.

[0048] According to one embodiment of this application, the ratio of the suction effect of the first negative pressure device on the second box to the suction effect provided by the first negative pressure device is greater than or equal to 5% and less than or equal to 30%.

[0049] In this embodiment, the first negative pressure device can simultaneously suction the first and second chambers. Ideally, the first negative pressure device can provide 100% suction. When the suction effect of the first negative pressure device on the second chamber is greater than 30%, the suction effect of the first negative pressure device on the first chamber is less than 70%, which can easily affect the suction force of solids and liquids on the surface to be cleaned, thereby affecting the cleaning effect.

[0050] When the suction effect of the first negative pressure device on the second chamber is less than 5%, the pressure change inside the second chamber is small, and the pressure difference between the second and first chambers is small. This can easily affect the suction force of the first chamber drawing liquid into the second chamber, thus affecting the speed at which liquid enters the second chamber from the first chamber. As more and more liquid accumulates in the first chamber, the liquid level rises. Therefore, during the suction process of the first negative pressure device, it is easy to draw liquid from the first chamber towards the first negative pressure device, affecting the normal operation of the cleaning equipment.

[0051] In summary, in this embodiment of the application, by setting the ratio of the suction effect of the first negative pressure device on the second box to the suction effect provided by the first negative pressure device to be greater than or equal to 5% and less than or equal to 30%, the above-mentioned technical problems can be effectively solved.

[0052] According to one embodiment of this application, a second negative pressure device is also included, which is connected to the second housing and provides the second negative pressure environment for the second housing.

[0053] In this embodiment, when the second negative pressure device is used to provide a negative pressure environment for the second chamber, the first negative pressure device can be used only to provide a first negative pressure environment for the first chamber. The second negative pressure device and the first negative pressure device can be independent of each other and do not affect each other, thereby facilitating the control of the air pressure in the first negative pressure environment and the second negative pressure environment.

[0054] According to one embodiment of this application, the first negative pressure device and the second negative pressure device respectively provide a suction effect on the first box and the second box;

[0055] The second negative pressure device is used to create the second negative pressure environment at the same time or after the first negative pressure environment is created in the first chamber.

[0056] In this embodiment, the suction effect of the second negative pressure device on the second chamber can be no earlier than the suction effect of the first negative pressure device on the first chamber, so as to reduce the possibility that the second chamber will suction the first chamber when there is no liquid in the first chamber, which would cause abnormal noise between the first and second chambers and also lead to energy loss, thereby affecting the endurance of the cleaning equipment.

[0057] The first and second negative pressure devices can operate simultaneously. At this time, solids and liquids on the surface to be cleaned can be drawn into the first chamber. Simultaneously, the second chamber can draw liquid from the first chamber, allowing it to enter the second chamber. The simultaneous operation of the first and second negative pressure devices increases the flow rate of liquid from the first chamber into the second chamber, reducing the possibility of excessive liquid level in the first chamber causing backflow towards the first negative pressure device. It also effectively reduces the force required for the user to hold the cleaning equipment.

[0058] Alternatively, the first negative pressure device can operate before the second negative pressure device. The first negative pressure device can first suction the solids and liquids on the surface to be cleaned, drawing them into the first chamber. Then, the second negative pressure device can be activated, allowing the liquid in the first chamber to be drawn into the second chamber.

[0059] According to one embodiment of this application, it further includes an airflow duct, one end of which is connected to the first negative pressure device, and the other end of which is connected to the second housing.

[0060] In this embodiment of the application, when the first negative pressure device can provide a second negative pressure environment for the second chamber, the first negative pressure device and the second chamber can be connected through an airflow pipe. During the operation of the first negative pressure device, air can be drawn from the second chamber through the airflow pipe to reduce the air pressure inside the second chamber, thereby creating a second negative pressure environment.

[0061] According to one embodiment of this application, it further includes a suction channel, one end of which is connected to the surface to be cleaned, and the other end of which is connected to the first housing. The suction channel is used to guide the liquid and the solid from the surface to be cleaned to the first housing.

[0062] The suction channel is provided with a baffle plate on the side facing the first negative pressure device. The baffle plate is used to prevent the solid and the liquid from being sprayed out to the outside of the first box.

[0063] In this embodiment, the suction channel can connect the first chamber and the external environment so that when the first chamber is in a first negative pressure environment, the dirt on the surface to be cleaned can be sucked into the first chamber.

[0064] The suction channel can have a suction port and a discharge port. The suction port corresponds to the surface to be cleaned, and the discharge port can be located inside the first chamber. When the first negative pressure device is running, it can suck up the first chamber, creating a first negative pressure environment inside the first chamber. The air pressure inside the first chamber is lower than the air pressure of the external environment at the suction port. Under the action of the air pressure difference, solids and liquids on the surface to be cleaned at the suction port can be automatically sucked into the suction channel and discharged into the first chamber through the discharge port of the suction channel.

[0065] Solids and liquids on the surface to be cleaned can flow from bottom to top within the suction channel under the influence of air pressure difference. To prevent solids and liquids sucked into the suction channel from flowing back downwards, they are typically sprayed into the first housing when discharged from the drain port. By installing a baffle plate on the side of the first suction channel facing the first negative pressure device, the possibility of solids and liquids sprayed from the drain port of the suction channel entering the first negative pressure device can be reduced, thus improving the operational reliability of the first negative pressure device.

[0066] According to one embodiment of this application, a liquid conduit is further included, one end of which is connected to the drain port of the first housing, and the other end of which is connected to the second housing.

[0067] In this embodiment, the liquid conduit can be used to transfer liquid from the first chamber to the second chamber. By transferring the liquid to the second chamber on the floor brush assembly, the weight of the machine body can be reduced and the center of gravity lowered, which helps to reduce the hand strength required by the user to clean the equipment.

[0068] According to one embodiment of this application, a clean water tank is also included, the clean water tank being disposed on the floor brush assembly.

[0069] In this embodiment, the clean water tank provides clean water to the roller brush, the surface to be cleaned, etc. The clean water tank stores clean water to provide significant gravity. By positioning the clean water tank on the floor brush assembly, the center of gravity of the cleaning device can be lowered, reducing the user's hand-holding effort and improving the stability of the cleaning device.

[0070] According to one embodiment of this application, the clean water tank and the second tank body are detachably connected to the floor brush assembly.

[0071] In this embodiment, both the clean water tank and the second tank can be mounted on the floor brush assembly. The clean water tank and the second tank can be disassembled independently. When it is necessary to store clean water, only the clean water tank can be removed from the floor brush assembly. When it is necessary to clean the second tank, only the second tank can be removed from the floor brush assembly. The independent disassembly of the clean water tank and the second tank facilitates user maintenance of both.

[0072] The clean water tank and the second tank can be arranged side by side. Since both the clean water tank and the second tank can be used to store liquid, arranging them side by side on the floor brush assembly can make the force on the floor brush assembly relatively balanced, thereby improving the uniformity of the pressure exerted by the floor brush assembly on the ground and enhancing the cleaning effect.

[0073] According to one embodiment of this application, the clean water tank and the second tank are an integral structure, and the clean water tank and the second tank are detachable from the floor brush assembly.

[0074] In this embodiment, the clean water tank and the second tank can be non-removable. By making the clean water tank and the second tank an integral structure, the stability of the connection between the clean water tank and the second tank and the floor brush assembly can be improved, reducing the possibility of the clean water tank and the second tank shaking and causing abnormal noise during cleaning. Furthermore, it also allows the floor brush assembly to have a better aesthetic appearance, which is beneficial to improving the appearance of the cleaning equipment.

[0075] According to one embodiment of this application, a drying device is also included, which is connected to at least one of the first housing and the suction channel, and the drying device is used at least for drying the first housing and the suction channel.

[0076] In this embodiment, the drying device can provide hot airflow to at least one of the first box and the suction channel, so that the first box and the suction channel can be kept dry, thereby reducing the possibility that the interior of the first box and the suction channel will be in a humid environment for a long time, leading to the growth of bacteria and the generation of odors.

[0077] Since the first chamber is connected to the suction channel, when the drying device provides hot airflow to either the first chamber or the suction channel, the first chamber and the suction channel can be dried.

[0078] Secondly, this application provides a cleaning system comprising:

[0079] Base station or base station;

[0080] The cleaning device described in any of the above embodiments may be placed on a base or a base station.

[0081] The beneficial effects of the cleaning equipment provided in this application are:

[0082] The separate design of the wastewater tank, with a second tank for storing liquid located on the floor brush assembly at a relatively lower position, reduces the weight and center of gravity of the machine, significantly reducing the force required for users to hold the cleaning equipment and achieving a labor-saving effect.

[0083] The overall weight of the cleaning equipment has not changed significantly. Therefore, the pressure of the floor brush assembly on the ground can be maintained while reducing the user's hand strength, thus ensuring the cleaning effect.

[0084] Furthermore, since the second tank for storing liquid is located on the floor brush assembly, some space in the machine body can be freed up, allowing the first tank to be moved down, so that the first negative pressure device can also be moved down, thereby lowering the center of gravity of the machine body to achieve a more effective labor-saving effect.

[0085] In addition, since the liquid in the first chamber can enter the second chamber, and the first chamber contains solids and a small amount of liquid, it is easier to dry the first chamber, reducing the possibility that the first chamber and the suction channel will be in a humid environment for a long time, which may lead to the growth of bacteria or the generation of odors.

[0086] In addition to the technical problems solved by the embodiments of the present invention, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions as described above, other technical problems that can be solved by the cleaning equipment and cleaning system provided by the embodiments of the present invention, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific embodiments.

[0103] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0104] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. Clearly, the described embodiments are only a portion, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0105] This application provides a cleaning device, which may be, but is not limited to, a floor scrubber. This application uses a floor scrubber as an example. A floor scrubber is a device used for cleaning floors and generally consists of multiple parts such as a brush assembly, a roller brush, a clean water tank, and a wastewater tank. The working principle of the floor scrubber is as follows: the high-speed rotation of the motor drives the roller brush to rotate at high speed, while the clean water tank rotates, spraying clean water forward onto the roller brush through the water path. Combined with the high-speed rotation of the roller brush, solid and liquid debris from the surface to be cleaned is sucked into the wastewater tank through a vacuum suction channel located behind the roller brush and another water path, thus completing the cleaning process.

[0106] However, during the cleaning process, as the wastewater tank continuously pumps solid and liquid waste from the surface to be cleaned, the weight of the wastewater tank will continue to increase. This will increase the force required for the user to hold the cleaning equipment, making it more strenuous to operate and affecting the user experience.

[0107] The applicant found that while reducing the weight of the cleaning equipment by reducing the weight of the wastewater tank or the machine body can reduce the force the user has to hold the cleaning equipment, the reduction in the weight of the cleaning equipment will lead to a decrease in the pressure of the floor brush on the ground, which will affect the cleaning effect on stubborn stains on the floor and thus affect the user's user experience.

[0108] Based on the aforementioned technical problems, the applicant has improved the structure of existing cleaning equipment. In the embodiments of this application, the wastewater tank may include a first tank and a second tank. The first tank is mainly used to store solids (garbage). The second tank is mainly used to store liquids (garbage). The first tank is generally lighter than the second tank. Furthermore, during cleaning, the height of the machine body is generally higher than the height of the floor brush assembly. By placing the first tank for storing solids in the machine body and the second tank for storing liquids in the floor brush assembly, the weight of the machine body can be reduced, and the center of gravity of the machine body can be lowered, allowing the user to save hand strength and operate the cleaning equipment with ease.

[0109] Furthermore, since the second tank for storing liquid is located on the floor brush assembly, the overall weight of the cleaning equipment does not change significantly. Therefore, while saving the user's hand strength, the floor brush assembly can maintain pressure on the ground to ensure effective cleaning of stubborn stains on the surface to be cleaned.

[0110] The floor brush assembly, cleaning equipment, and cleaning system provided in this application are described below with reference to the accompanying drawings and specific embodiments.

[0111] See Figure 1 and Figure 2As shown, the cleaning device 100 of this application embodiment includes a floor brush assembly 110, a body 120, and a wastewater tank 130.

[0112] The floor brush assembly 110 can be used to clean surfaces. The main body 120 is connected to the floor brush assembly 110. The user can hold the handle on the main body 120 to operate the cleaning device 100 to move forward or backward.

[0113] The wastewater tank 130 may include a first tank 131 and a second tank 132. The first tank 131 may be disposed on the body 120. The first tank 131 may be used to receive solids and liquids recovered from the surface to be cleaned.

[0114] The second housing 132 is a separate structure from the first housing 131. The second housing 132 can be installed on the floor brush assembly 110. The second housing 132 is connected to the first housing 131. The second housing 132 can be used to partially receive the liquid in the first housing 131.

[0115] Solids can be stored in the first chamber 131, while liquids can enter the second chamber 132.

[0116] In this embodiment, it is readily understood that the weight of the liquid generated during the cleaning process is usually much greater than the weight of the solid. Therefore, the weight of the second housing 132 is usually greater than the weight of the first housing 131. Furthermore, since the first housing 131 is disposed on the body 120 and the second housing 132 is disposed on the floor brush assembly 110, the height of the body 120 is usually higher than the height of the floor brush assembly 110 during the cleaning process. Therefore, by placing the heavier second housing 132 on the relatively lower floor brush assembly 110, the weight of the body 120 can be reduced, and the center of gravity of the body 120 can be lowered.

[0117] During the cleaning process, the user holds the grip on the main body 120 to operate the cleaning device 100 to clean the surface to be cleaned. When the liquid in the first tank 131 enters the second tank 132, the first tank 131 retains solids and a small amount of liquid, which reduces the weight of the main body 120 and lowers its center of gravity. This reduces the weight of the main body 120 and the gravitational lever arm of the main body 120 relative to the rotation point of the floor brush assembly 110. Therefore, it can effectively reduce the hand force exerted by the user on the cleaning device 100, which helps to achieve a labor-saving effect and improve the user experience.

[0118] Specifically, during the cleaning process, the cleaning device 100 maintains an angle of inclination between the device body 120 and the surface to be cleaned. The direction of the user's hand-held force on the cleaning device 100 is opposite to the direction of the device body 120's gravity. The product of the user's hand-held force and its lever arm is greater than or equal to the product of the device body 120's gravity and its lever arm. The flow of liquid from the first housing 131 into the second housing 132 reduces the weight within the first housing 131, thus lightening the weight of the device body 120 and lowering its center of gravity. Consequently, both the weight of the device body 120 and its lever arm are reduced, resulting in a significant decrease in the product of the weight and its lever arm. When the lever arm of the hand-held force remains constant, the user's hand-held force is effectively reduced, achieving a labor-saving effect.

[0119] Furthermore, since the liquid in the first housing 131 can enter the second housing 132 on the floor brush assembly 110, the gravity of the liquid can still act on the floor brush assembly 110 to ensure the pressure of the floor brush assembly 110 on the ground, thereby ensuring the cleaning effect on the surface to be cleaned, especially for stubborn stains.

[0120] In addition, since the liquid in the first chamber 131 can enter the second chamber 132, and a small amount of liquid remains in the first chamber 131, it is relatively easy to dry the first chamber 131, thereby reducing the possibility that the dirt in the first chamber 131 will remain in a humid environment for a long time, leading to the growth of bacteria or the generation of odors.

[0121] Since the first housing 131 is located on the body 120 and the second housing 132 is located on the floor brush assembly 110, the height of the first housing 131 relative to the surface to be cleaned is higher than the height of the second housing 132 relative to the surface to be cleaned. Therefore, the liquid in the first housing 131 can enter the second housing 132 under the action of gravitational potential energy.

[0122] It should be noted that in this embodiment, the first tank 131 and the second tank 132 are separate structures, therefore, the first tank 131 and the second tank 132 can be cleaned independently. Since the liquid in the first tank 131 can flow into the second tank 132, the first tank 131 is mainly used for storing solids, and the second tank 132 is mainly used for storing liquids. This facilitates the user's sorting of dirt and grime, thereby improving the cleaning efficiency of the wastewater tank 130. Furthermore, it also reduces the possibility of solid and liquid mixtures clogging the drain pipes.

[0123] See also some of the possible implementation methods. Figure 2 and Figure 3As shown, the first housing 131 of this embodiment is provided with a drain port 131a. The drain port 131a can be used to transport liquid in the first housing 131 to the second housing 132. The drain port 131a is located at the lowest position of the first housing 131.

[0124] In this embodiment, the liquid in the first housing 131 can enter the second housing 132 through the drain port 131a. By setting the drain port 131a at the lowest position of the first housing 131, the liquid in the first housing 131 can be drained more easily, which helps to reduce the possibility of liquid remaining in the bottom or edge areas of the first housing 131.

[0125] See also some of the possible implementation methods. Figure 2 and Figure 3 As shown, the first housing 131 of this application embodiment has a bottom wall 1311. The bottom wall 1311 is inclined. A drain port 131a is provided on the bottom wall 1311, and the drain port 131a is located at the lowest point of the bottom wall 1311, so that the drain port 131a is located at the lowest position of the first housing 131.

[0126] It should be noted that the inclined setting of the bottom wall 1311 means that the bottom wall 1311 of the cleaning device 100 has an inclined angle with the horizontal plane in cleaning mode, static mode or charging mode.

[0127] In this embodiment, the bottom wall 1311 is inclined, allowing it to guide the liquid within the first tank 131 towards the drain port 131a, thereby improving drainage efficiency. Furthermore, since the drain port 131a is located at the lowest point of the bottom wall 1311, liquid at the lowest point of the bottom wall 1311 can enter the second tank 132 through the drain port 131a, reducing the likelihood of liquid remaining at the lowest position of the first tank 131.

[0128] It's easy to understand that the presence of liquid inside the first chamber 131 has several negative consequences. First, it increases the weight of the first chamber 131, affecting the lightweight design of the main body 120 and thus reducing the effort required to hold the device. Second, it exacerbates the humidity level inside the first chamber 131, making it prone to bacterial growth and unpleasant odors. Furthermore, it hinders the drying process of the first chamber 131.

[0129] Furthermore, when the cleaning device 100 is stationary or charging, the body 120 can tilt forward relative to the brush assembly 110 along the forward direction of the cleaning device 100 to stabilize the center of gravity of the cleaning device 100 and prevent it from tipping over. The tilted body 120 can also provide a certain forward thrust to assist the user in pushing the cleaning device 100 forward, reducing the burden on the user.

[0130] Therefore, by setting the bottom wall 1311 to be tilted, the possibility of liquid flowing back from the lowest position of the bottom wall 1311 to other directions can be reduced when the fuselage 120 is tilted forward.

[0131] In some examples, along the forward direction of the cleaning device 100, the first housing 131 may be located at the front of the body 120 or at the rear of the body 120, and this is not limited in the embodiments of this application.

[0132] For example, taking the first housing 131 located at the rear of the body 120 as an example, the bottom wall 1311 can be tilted downwards from front to back. Therefore, when the cleaning equipment 100 is stationary or charging so that the body 120 is tilted forward, the drain port 131a can be ensured to be located at the lowest position of the first housing 131. Thus, when the cleaning equipment 100 is running and the body 120 is tilted backwards, the drain port 131a can still be kept at the lowest position of the first housing 131, so as to more effectively reduce the possibility of liquid accumulating in the first housing 131.

[0133] See also some of the possible implementation methods. Figure 2 and Figure 3 As shown, the cleaning device 100 of this application embodiment may further include a separator 1312. The separator 1312 is located in the first housing 131. The separator 1312 can be used to separate solids and liquids in the first housing 131, so that solids are retained in the first housing 131 and liquids pass through the separator 1312 to enter the second housing 132.

[0134] In this embodiment, the separator 1312 can be used to screen solids within the first housing 131, retaining the solids within the first housing 131. This reduces the likelihood of solids entering the second housing 132 and affecting the solid-liquid separation effect. It also reduces the likelihood of solids clogging the drain port 131a, thus affecting the flow rate of liquid into the second housing 132.

[0135] Specifically, solids can be screened to the top of the separator 1312, while liquids can pass down through the separator 1312 and enter the second chamber 132 through the drain port 131a. In other words, solids can remain above the separator 1312, thus preventing solids from easily entering between the separator 1312 and the bottom wall 1311 of the first chamber 131, thereby reducing the possibility of solids clogging the drain port 131a.

[0136] In some examples, the separator 1312 may have multiple sieve holes. The size of the sieve holes can be set according to the application environment of the cleaning equipment 100. The sieve holes prevent solids from passing through while allowing liquids to pass through smoothly.

[0137] See also some of the possible implementation methods. Figure 2 and Figure 3 As shown, in this embodiment of the application, the separator 1312 is close to the bottom wall 1311 of the first housing 131.

[0138] It is easy to understand that the solids in the first chamber 131 will settle downwards under the influence of gravity. By placing the separator 1312 close to the bottom wall 1311, the amount of liquid contained between the separator 1312 and the bottom wall 1311 is reduced, which can decrease the possibility of liquid flowing in the first chamber 131 and the liquid between the separator 1312 and the bottom wall 1311 carrying the solids upwards and re-suspending them and mixing them in the liquid. This is beneficial to improving the separation efficiency and effect of solids and liquids.

[0139] Furthermore, when the liquid between the separator 1312 and the bottom wall 1311 causes the solids on the separator 1312 to resuspend, the solids will sink downwards again under the action of gravity. Moreover, the solids will cause secondary impact and wear on the separator 1312 under the action of liquid flow, which will affect the separation effect and service life of the separator 1312.

[0140] In some examples, the separator 1312 may also be inclined. The inclination direction of the separator 1312 may be the same as the inclination direction of the bottom wall 1311 of the first housing 131. The inclination angle of the separator 1312 may be the same as or different from the inclination angle of the bottom wall 1311, and is not limited in this embodiment.

[0141] In some feasible embodiments, the first chamber 131 of this application embodiment may have a first negative pressure environment for drawing solids and liquids from the surface to be cleaned into the first chamber 131. The second chamber 132 may have a second negative pressure environment. The second chamber 132 is under negative pressure relative to the first chamber 131.

[0142] When the second chamber 132 is under negative pressure, the air pressure of the second negative pressure environment can be lower than the air pressure of the first negative pressure environment, so that the liquid in the first chamber 131 can be automatically drawn into the second chamber 132.

[0143] In this embodiment, when the second chamber 132 is under negative pressure relative to the first chamber 131, it can provide the liquid in the first chamber 131 with the power to flow to the second chamber 132. Under the influence of gravitational potential energy and the second negative pressure environment in the second chamber 132, the liquid in the first chamber 131 can be quickly drawn into the second chamber 132, thereby reducing the slow flow speed of the liquid from the first chamber 131 to the second chamber 132, which makes it difficult to release the weight of the machine body 120, and the possibility that the user still has a lot of hand strength on the cleaning device 100.

[0144] The first negative pressure environment within the first housing 131 refers to a situation where the air pressure inside the first housing 131 is lower than the air pressure of the external environment (e.g., the surface to be cleaned), thus creating a first negative pressure environment relative to the external environment. The air pressure in the external environment and the air pressure inside the first housing 131 create a pressure difference, which allows solids and liquids on the surface to be cleaned to be automatically drawn into the first housing 131 under the influence of this pressure difference.

[0145] The second negative pressure environment within the second chamber 132 can refer to the air pressure within the second chamber 132 being lower than the air pressure within the first chamber 131, thus forming a second negative pressure environment relative to the first chamber 131. A pressure difference can be created between the air pressure within the first chamber 131 and the air pressure within the second chamber 132. Under the influence of this pressure difference, solids and liquids within the first chamber 131 can flow towards the drain port 131a. Solids within the first chamber 131 are blocked by the separator 1312 and retained within the first chamber 131. Liquids within the first chamber 131 can be drawn into the second chamber 132 through the separator 1312.

[0146] See also some of the possible implementation methods. Figure 2 and Figure 3 As shown, the cleaning equipment 100 also includes a first negative pressure device 140. The first negative pressure device 140 is disposed on the body 120. The first negative pressure device 140 is connected to the first housing 131. The first negative pressure device 140 provides the first housing 131 with a first negative pressure environment.

[0147] In this embodiment of the application, the first negative pressure environment is connected to the first box 131. When the first negative pressure environment is running, the air inside the first box 131 can be extracted to provide the first negative pressure environment for the first box 131.

[0148] In some examples, the first negative pressure device 140 can be an electric motor. The high-speed operation of the motor can drive a fan or impeller to rotate rapidly to extract air from the first chamber 131, so that the air pressure inside the first chamber 131 is lower than the air pressure of the external environment, and solids and liquids on the surface to be cleaned can be automatically sucked into the first chamber 131.

[0149] It should be noted that, in this embodiment, since the first housing 131 and the second housing 132 are separate structures for storing solids and liquids respectively, and the second housing 132 is located on the floor brush assembly 110, the first housing 131 can occupy less space in the body 120. The height of the first housing 131 can be reduced, thereby allowing the position of the first negative pressure device 140 to be lowered. Since the first negative pressure device 140 has a certain weight, lowering its position can lower the center of gravity of the body 120, thereby more effectively reducing the hand force exerted by the user on the cleaning device 100.

[0150] See also some of the possible implementation methods. Figure 2 and Figure 3 As shown, in this embodiment of the application, the first negative pressure device 140 is connected to the second housing 132. The first negative pressure device 140 provides the second housing 132 with a second negative pressure environment. The first negative pressure device 140 simultaneously draws air from the first housing 131 and the second housing 132.

[0151] In this embodiment of the application, the first negative pressure device 140 can be used to provide a first negative pressure environment for the first housing 131, and the first negative pressure device 140 can also be used to provide a second negative pressure environment for the second housing 132. Figure 3 The direction indicated by the middle arrow is the airflow direction within the first housing 131, the second housing 132, and the suction channel 160 when the first negative pressure device 140 is operating. Therefore, the first negative pressure device 140 can simultaneously suction the first housing 131 and the second housing 132, ensuring that the air pressure in the second negative pressure environment is lower than that in the first negative pressure environment. This eliminates the need for additional equipment on the cleaning equipment 100 to create a second negative pressure environment in the second housing 132, saving space and reducing the likelihood of increased weight and cost due to such equipment.

[0152] It should be noted that the first negative pressure device 140 suctions the first chamber 131, creating a first negative pressure environment inside the first chamber 131. Furthermore, since the first chamber 131 is connected to the external environment, solids and liquids on the surface to be cleaned can be drawn into the first chamber 131, and outside air can enter the first chamber 131. Therefore, when the first negative pressure device 140 simultaneously suctions the first chamber 131 and the second chamber 132, the air pressure inside the first chamber 131 can switch between the air pressure of the external environment and the air pressure under the first negative pressure environment. When the first negative pressure environment is formed inside the first chamber 131, the air pressure inside the first chamber 131 is lower than the air pressure of the external environment, thus drawing solids and liquids from the surface to be cleaned into the first chamber 131. When the air pressure inside the first chamber 131 is close to the air pressure of the external environment, the air pressure inside the second chamber 132 is less than the air pressure inside the first chamber 131. Under the action of the air pressure difference between the second chamber 132 and the first chamber 131, the liquid inside the first chamber 131 is drawn into the second chamber 132.

[0153] In some feasible ways, the suction effect of the first negative pressure device 140 on the first housing 131 is greater than the suction effect on the second housing 132.

[0154] In this embodiment of the application, during the cleaning process, the cleaning device 100 mainly relies on the air pressure inside the first housing 131 being lower than the air pressure of the external environment to achieve the suction of solids and liquids on the surface to be cleaned. Therefore, when the first negative pressure device 140 simultaneously suctions the first housing 131 and the second housing 132, by setting the suction effect of the first negative pressure device 140 on the first housing 131 to be greater than the suction effect on the second housing 132, the suction force on the surface to be cleaned can be guaranteed, thereby ensuring the cleaning effect of the surface to be cleaned.

[0155] In some possible implementations, the ratio of the suction effect of the first negative pressure device 140 on the second housing 132 to the suction effect provided by the first negative pressure device 140 is greater than or equal to 5% and less than or equal to 30%.

[0156] In this embodiment, the first negative pressure device 140 can simultaneously suction the first housing 131 and the second housing 132. Ideally, the first negative pressure device 140 can provide 100% suction. When the suction effect of the first negative pressure device 140 on the second housing 132 is greater than 30%, the suction effect of the first negative pressure device 140 on the first housing 131 is less than 70%, which can easily affect the suction force of solids and liquids on the surface to be cleaned, thereby affecting the cleaning effect.

[0157] When the suction effect of the first negative pressure device 140 on the second chamber 132 is less than 5%, the air pressure change inside the second chamber 132 is small, and the pressure difference between the second chamber 132 and the first chamber 131 is small. This can easily affect the suction force of the first chamber 131 drawing liquid into the second chamber 132, thus affecting the speed at which liquid enters the second chamber 132 from the first chamber 131. As more and more liquid accumulates in the first chamber 131, the liquid level rises. Therefore, during the suction process of the first negative pressure device 140 on the first chamber 131, the liquid in the first chamber 131 is easily drawn towards the first negative pressure device 140, affecting the normal operation of the cleaning equipment 100.

[0158] In summary, in this embodiment of the application, by setting the ratio of the suction effect of the first negative pressure device 140 on the second box 132 to the suction effect provided by the first negative pressure device 140 to be greater than or equal to 5% and less than or equal to 30%, the above-mentioned technical problems can be effectively solved.

[0159] In some examples, the suction effect of the first negative pressure device 140 on the second box 132 can be set to 20%, and the suction effect of the first negative pressure device 140 on the first box 131 can be set to 80%.

[0160] In some possible implementations, the cleaning device 100 may include a second negative pressure device (not shown). The second negative pressure device is connected to the second housing 132. The second negative pressure device provides the second housing 132 with a second negative pressure environment.

[0161] In this embodiment, when the second negative pressure device is used to provide a negative pressure environment for the second housing 132, the first negative pressure device 140 can be used only to provide a first negative pressure environment for the first housing 131. The second negative pressure device and the first negative pressure device 140 can be independent of each other and do not affect each other, thereby facilitating the control of the air pressure in the first negative pressure environment and the second negative pressure environment.

[0162] The second negative pressure device can be installed on the body 120 or on the floor brush assembly 110, and is not limited in this embodiment.

[0163] For example, the second negative pressure device can be disposed on the floor brush assembly 110. On the one hand, it can reduce the possibility that the increased weight of the body 120 will lead to an increase in the hand strength of the user in the cleaning device 100. On the other hand, since both the second negative pressure device and the second housing 132 are disposed on the floor brush assembly 110, it can facilitate the control of the air pressure in the second housing 132 by the second negative pressure device, thereby reducing energy loss.

[0164] In some examples, the second negative pressure device may be, but is not limited to, an air pump.

[0165] In some feasible embodiments, the first negative pressure device 140 and the second negative pressure device can respectively provide suction to the first housing 131 and the second housing 132. The second negative pressure device can be used to create a second negative pressure environment simultaneously with or after the first negative pressure environment is created in the first housing 131.

[0166] In this embodiment, the suction effect of the second negative pressure device on the second housing 132 can be no earlier than the suction effect of the first negative pressure device 140 on the first housing 131, so as to reduce the possibility that when there is no liquid in the first housing 131, the second housing 132 will suck the first housing 131, causing abnormal noise between the airflow in the first housing 131 and the second housing 132, and will also lead to energy loss, thereby affecting the endurance of the cleaning equipment 100.

[0167] The first negative pressure device 140 and the second negative pressure device can operate simultaneously. At this time, solids and liquids on the surface to be cleaned can be drawn into the first chamber 131. Simultaneously, the second chamber 132 can draw liquid from the first chamber 131, allowing the liquid to enter the second chamber 132. The simultaneous operation of the first negative pressure device 140 and the second negative pressure device increases the flow rate of liquid from the first chamber 131 into the second chamber 132, reducing the possibility of excessive liquid level in the first chamber 131 causing backflow towards the first negative pressure device 140, and effectively alleviating the user's hand pressure on the cleaning device 100.

[0168] Alternatively, the first negative pressure device 140 can operate before the second negative pressure device. The first negative pressure device 140 can first suction the solids and liquids on the surface to be cleaned, drawing them into the first chamber 131. Then, the second negative pressure device can be activated, allowing the liquid in the first chamber 131 to be drawn into the second chamber 132.

[0169] In some possible implementations, the cleaning device 100 may also include an airflow duct 150. One end of the airflow duct 150 is connected to the first negative pressure device 140. The other end of the airflow duct 150 is connected to the second housing 132.

[0170] In this embodiment of the application, when the first negative pressure device 140 can provide a second negative pressure environment for the second housing 132, the first negative pressure device 140 and the second housing 132 can be connected through the airflow pipe 150. During the operation of the first negative pressure device 140, air can be drawn from the second housing 132 through the airflow pipe 150 to reduce the air pressure inside the second housing 132, thereby forming a second negative pressure environment.

[0171] In some examples, a portion of the airflow duct 150 may be located on the body 120 and extend toward the first negative pressure device 140. A portion of the airflow duct 150 may be located on the floor brush assembly 110 for communication with the interior space of the second housing 132 on the floor brush assembly 110.

[0172] In some possible implementations, the cleaning device 100 may also include a suction channel 160. One end of the suction channel 160 communicates with the surface to be cleaned. The other end of the suction channel 160 communicates with a first housing 131. The suction channel 160 is used to guide solids and liquids from the surface to be cleaned into the first housing 131.

[0173] The suction channel 160 is provided with a baffle plate 170 on the side facing the first negative pressure device 140. The baffle plate 170 can be used to prevent solids and liquids from being sprayed out to the outside of the first housing 131.

[0174] In this embodiment, the suction channel 160 can connect the first housing 131 and the external environment so that when the first housing 131 is in a first negative pressure environment, the dirt on the surface to be cleaned can be sucked into the first housing 131.

[0175] The suction channel 160 may have a suction port 160a and a discharge port 160b. The suction port 160a is connected to the surface to be cleaned. Solids and liquids on the surface to be cleaned can enter the suction port 160a through the channel between the roller brush 111 and the scraper 112. The discharge port 160b may be located inside the first housing 131. When the first negative pressure device 140 is running, it can suck up the first housing 131, creating a first negative pressure environment in the first housing 131. The air pressure inside the first housing 131 is lower than the air pressure of the external environment at the suction port 160a. Under the action of the air pressure difference, solids and liquids on the surface to be cleaned at the suction port 160a can be automatically sucked into the suction channel 160 and discharged into the first housing 131 through the discharge port 160b of the suction channel 160.

[0176] Solids and liquids on the surface to be cleaned can flow from bottom to top within the suction channel 160 under the influence of air pressure difference. To prevent solids and liquids sucked into the suction channel 160 from flowing back downwards within it, they are typically sprayed into the first housing 131 when discharged from the drain port 160b. By providing a baffle plate 170 on the side of the first suction channel 160 facing the first negative pressure device 140, the possibility of solids and liquids sprayed from the drain port 160b of the suction channel 160 entering the first negative pressure device 140 can be reduced, thus improving the operational reliability of the first negative pressure device 140.

[0177] In some examples, the cross-sectional area of ​​the airflow channel can be smaller than that of the suction channel 160 to ensure sufficient suction force on the surface to be cleaned, thereby ensuring a good cleaning effect. The direction of the cross-section can be perpendicular to the direction of airflow.

[0178] It should be noted that the shape of the baffle plate 170 can be set according to the internal structure of the body 120, and the shape of the baffle plate 170 is not limited in this embodiment. For example, part of the baffle plate 170 can be located above the drain outlet 160b of the suction channel 160.

[0179] In some possible implementations, the cleaning device 100 may also include a liquid conduit (not shown). One end of the liquid conduit may be connected to a drain port 131a of the first housing 131. The other end of the liquid conduit may be connected to a second housing 132.

[0180] In this embodiment, the liquid conduit can be used to transfer liquid from the first housing 131 into the second housing 132. By transferring the liquid into the second housing 132 on the floor brush assembly 110, the weight of the body 120 can be reduced and the center of gravity lowered, which helps to reduce the hand strength of the user in handling the cleaning device 100.

[0181] See also some of the possible implementation methods. Figure 2 As shown, the cleaning device 100 may also include a clean water tank 180. The clean water tank 180 may be mounted on the floor brush assembly 110.

[0182] In this embodiment, the clean water tank 180 can provide clean water to the roller brush 111, the surface to be cleaned, etc. The clean water tank 180 stores clean water to have a large gravity. By setting the clean water tank 180 on the floor brush assembly 110, the center of gravity of the cleaning device 100 can be lowered, thereby reducing the hand strength of the user on the cleaning device 100 and improving the stability of the cleaning device 100.

[0183] In some possible implementations, the clean water tank 180 and the second tank 132 are detachably connected to the floor brush assembly 110.

[0184] In this embodiment, both the clean water tank 180 and the second tank 132 can be mounted on the floor brush assembly 110. The clean water tank 180 and the second tank 132 can be disassembled independently. When it is necessary to store clean water, only the clean water tank 180 can be removed from the floor brush assembly 110. When it is necessary to clean the second tank 132, only the second tank 132 can be removed from the floor brush assembly 110. The independent disassembly of the clean water tank 180 and the second tank 132 facilitates user maintenance of both.

[0185] The clean water tank 180 and the second tank 132 can be arranged side by side. Since both the clean water tank 180 and the second tank 132 can be used to store liquid, by arranging the clean water tank 180 and the second tank 132 side by side on the floor brush assembly 110, the force on the floor brush assembly 110 can be relatively balanced, thereby improving the uniformity of the pressure exerted by the floor brush assembly 110 on the ground and improving the cleaning effect.

[0186] It should be noted that this application embodiment does not limit the direction in which the clean water tank 180 and the second tank 132 are arranged side by side. For example, the clean water tank 180 and the second tank 132 can be arranged front to back along the forward direction of the cleaning equipment 100. The clean water tank 180 can be positioned forward or backward. Alternatively, the clean water tank 180 and the second tank 132 can also be arranged left to right along the width direction of the cleaning equipment 100. The clean water tank 180 can be positioned to the left or right.

[0187] In some examples, the clean water tank 180 and the second tank 132 may be detachably connected to the floor brush assembly 110 by means of snap-fit, hook-fit, or other means.

[0188] In some examples, the clean water tank 180 and the second tank 132 can also be connected to each other. The clean water tank 180 and the second tank 132 can be detachably connected to form a whole, and then detachably connected to the floor brush assembly 110.

[0189] In other examples, the clean water tank 180 and the second tank 132 can be an integral structure. The clean water tank 180 and the second tank 132 are detachable from the floor brush assembly 110.

[0190] In this embodiment, the clean water tank 180 and the second housing 132 may be non-removable. By making the clean water tank 180 and the second housing 132 an integral structure, the stability of the connection between the clean water tank 180 and the second housing 132 and the floor brush assembly 110 can be improved, reducing the possibility of the clean water tank 180 and the second housing 132 shaking and causing abnormal noise during cleaning. Furthermore, it also allows the floor brush assembly 110 to have a better aesthetic appearance, which is beneficial to improving the appearance of the cleaning equipment 100.

[0191] In some possible implementations, the cleaning device 100 may also include a drying device (not shown). The drying device is in communication with at least one of the first housing 131 and the suction channel 160. The drying device is used at least to dry the first housing 131 and the suction channel 160.

[0192] In this embodiment, the drying device can provide hot airflow to at least one of the first box 131 and the suction channel 160 so that the first box 131 and the suction channel 160 can be kept dry, thereby reducing the possibility that the interior of the first box 131 and the suction channel 160 will be in a humid environment for a long time, which may lead to the growth of bacteria and the generation of odors.

[0193] Since the first chamber 131 is connected to the suction channel 160, when the drying device provides hot airflow to either the first chamber 131 or the suction channel 160, the drying process of the first chamber 131 and the suction channel 160 can be achieved.

[0194] The drying device may include a heating element (not shown). The heating element can be used to provide heat. The cleaning device 100 may also include a power unit for causing airflow. The power unit can cause the heat generated by the heating element to flow, forming a hot airflow. The hot airflow flows within the first housing 131 and the suction channel 160 to achieve drying treatment of the first housing 131 and the suction channel 160.

[0195] In some examples, the first negative pressure device 140 can be used to power the flow of hot air. When the heating element approaches the suction port 160a of the suction channel 160, the first negative pressure device 140 is activated to create a first negative pressure environment in the first housing 131. The airflow at the suction port 160a can flow along the extension direction of the suction channel 160 and enter the first housing 131 through the discharge port 160b, so that the hot airflow can circulate throughout the suction channel 160 and the first housing 131 to dry the suction channel 160 and the first housing 131.

[0196] It should be noted that since the operation of the first negative pressure device 140 can also be used to suck up solids and liquids on the surface to be cleaned, the first negative pressure device 140 can be controlled by the controller to operate separately to achieve the cleaning function of the surface to be cleaned and the drying function of the suction channel 160 and the first box 131.

[0197] For example, in the cleaning mode of the cleaning equipment 100, the first negative pressure device 140 can be used to suck solids and liquids on the surface to be cleaned into the first housing 131. When the cleaning equipment 100 stops running, the first negative pressure device 140 can be used to dry the suction channel 160 and the interior of the first housing 131.

[0198] In other examples, the flow of hot air can also be powered by other power units. For example, a motor and impeller can be used to enable the hot air to flow within the suction channel 160 and the first housing 131.

[0199] In some examples, the drying device can be mounted on a base or base station. The drying device can be used to dry the roller brush 111 after the cleaning equipment 100 has completed cleaning. At this time, the first negative pressure device 140 is activated to create a first negative pressure environment within the first housing 131. The hot airflow used to dry the roller brush 111 can enter the suction channel 160 through the suction port 160a under the influence of the pressure difference. After flowing through the entire suction channel 160, the hot airflow can enter the first housing 131 through the drain port 160b of the suction channel 160 and dry the first housing 131. After completing the drying operation, the hot airflow can flow out to the outside of the cleaning equipment 100, thus completing the entire drying process for the roller brush 111, the suction channel 160, and the first housing 131.

[0200] This application provides a cleaning system, which may include a base or a base station. The cleaning device 100 may be placed on the base or base station.

[0201] In some examples, the base can be used to clean and dry the roller brush 111 to prevent the roller brush 111 from being damp for a long time, which could lead to odors or bacteria.

[0202] In some examples, the base station may have a charging function. When the cleaning device 100 is placed on the base station, the cleaning device 100 can be charged and automatically fed and drained. The base and the base station may be separate structures, or they may be an integrated structure; this is not limited in the embodiments of this application.
