Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and more particularly to a housing structure and a cleaning device having the same. Background Technology

[0002] Cleaning equipment refers to robots capable of performing cleaning operations in environments without human guidance; a common example is the robotic vacuum cleaner. Existing robotic vacuum cleaners generally consist of a vacuum cleaner body, a dustbin housed within the body, and a water tank. When sweeping is needed, the vacuum cleaner body and dustbin work together to form a vacuum cleaner with sweeping and dust removal functions; when mopping is needed, the vacuum cleaner body and water tank work together to form a mopping machine. As can be seen, when switching between different cleaning modes, the dustbin or water tank needs to be frequently replaced. For example, when switching from sweeping mode to mopping mode, the dustbin must be removed first, and then the water tank installed; conversely, the water tank must be removed first, and then the dustbin installed. This results in a poor user experience.

[0003] To address the aforementioned issues, an integrated housing has emerged on the market, comprising a wastewater tank and a clean water tank. During operation, the robotic vacuum cleaner mixes wastewater and solid particles generated during sweeping and mopping and sucks them into the wastewater tank. This integrated housing contains a filter assembly. However, when the robotic vacuum cleaner is working, the movement of the housing during walking, turning, and obstacle crossing causes it to shake. There is a risk that the fluid inside the housing may come into contact with and be absorbed by the filter assembly, causing long-term blockage and significantly reducing its lifespan. Furthermore, the fluid may pass through the filter assembly and flow into the fan duct, damaging the fan's operation. Therefore, it is necessary to improve the existing technology to overcome the aforementioned shortcomings. Summary of the Invention

[0004] The purpose of this invention is to provide a housing structure and a cleaning device having the same, which can effectively prevent liquid contained in the first receiving cavity from entering the filter assembly, thereby effectively extending the service life of the filter assembly.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] In a first aspect of the present invention, a box structure is provided, comprising: a box body having a first receiving cavity and a first inlet and a first outlet communicating therewith; a filter assembly disposed at the first outlet; and a separation component having one end fixed in the first receiving cavity to form a mounting end, and the other end suspended in the first receiving cavity to form a suspended end; the separation component dividing the first receiving cavity into an inflow channel communicating with the first inlet and an outflow channel communicating with the first outlet; the suspended end forming a communication port with its portion facing the first receiving cavity, the inflow channel and the outflow channel communicating through the communication port; the mounting end being distributed above the suspended end, at least such that the top surface of the separation component forms a downwardly extending guide surface.

[0007] In one embodiment, the guide surface is a plane that slopes downward from the mounting end toward the suspended end.

[0008] In one embodiment, the separating component includes a mounting portion having the mounting end and a flow guide portion having the suspended end, wherein the end of the mounting portion away from the mounting end is connected to the end of the flow guide portion away from the suspended end; the flow guide surface is provided on the flow guide portion.

[0009] In one embodiment, the angle of inclination of the guide surface H relative to the horizontal plane is in the range of 1° to 5°.

[0010] In one embodiment, the filter assembly includes a mounting base detachably disposed on the top of the housing body, the top of the housing body being recessed downward to form a groove, and the mounting base being disposed within the groove.

[0011] In one embodiment, the first inlet is located on the side wall of the first receiving cavity, and the first outlet is located at the bottom of the groove.

[0012] In one embodiment, the housing structure further includes a sliding component and a fixing component connected together; wherein the mounting base and the groove are slidably connected by the sliding component, and when the mounting base slides into place on the groove, the fixing component is used to detachably fix the mounting base in the groove.

[0013] In one embodiment, the housing body further includes a second receiving cavity, which is located outside the first receiving cavity; wherein the first receiving cavity has a first center of mass, the second receiving cavity has a second center of mass, and the first center of mass and the second center of mass are located on the same vertical plane; the vertical plane is configured to divide the space occupied by the first receiving cavity and the second receiving cavity into a first region and a second region with equal media mass, the first region and the second region being located on opposite sides of the vertical plane.

[0014] In one embodiment, the number of the second receiving cavities is at least two, and the centroid of all the second receiving cavities is the second centroid.

[0015] In a second aspect of the present invention, a cleaning device is provided, comprising: a housing structure as described above.

[0016] The present invention has the following beneficial effects:

[0017] The box structure and cleaning device provided by the present invention can extend the inflow and outflow channels by setting a separation component, thereby preventing the liquid in the fluid in the first receiving cavity from contacting the filter assembly. Furthermore, one end of the separation component is fixed in the first receiving cavity to form an installation end, and the other end is suspended in the first receiving cavity to form a suspended end. The installation end of the separation component is distributed higher than the suspended end, thereby forming a downwardly extending guide surface on the top surface of the separation component. Under the action of the guide surface, the liquid in the fluid can flow back into the first receiving cavity, thereby preventing the liquid in the first receiving cavity from contacting the filter assembly and effectively extending the service life of the filter assembly.

[0035] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the terms "upper," "lower," "left," "right," "longitudinal," "lateral," "inner," "outer," "vertical," "horizontal," "top," and "bottom," etc., indicating orientation or positional relationships, are based solely on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0036] It should also be noted that, for ease of description, the accompanying drawings only show the parts relevant to the present invention, not the entire structure. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 14As shown, the present invention provides a box structure, including: a box body 100, having a first receiving cavity 111 and a first inlet 1111 and a first outlet 1112 communicating therewith; a filter assembly 200, disposed at the first outlet 1112; and a separating component 150, one end of the separating component 150 being fixed inside the first receiving cavity 111 to form a mounting end X, and the other end being suspended inside the first receiving cavity 111 to form a suspended end Y; the separating component 150 divides the first receiving cavity 111 into an inflow channel communicating with the first inlet 1111 and an outflow channel communicating with the first outlet 1112; a connecting port 170 is formed between the suspended end Y and its portion facing the first receiving cavity 111, and the inflow channel and the outflow channel are connected through the connecting port 170; the mounting end X is distributed higher than the suspended end Y, at least such that the top surface of the separating component 150 forms a downwardly extending guide surface H.

[0038] The aforementioned housing structure can be applied to cleaning equipment such as vacuum cleaners, sweepers, mops, and floor scrubbers. The first receiving cavity 111 is used to contain fluid, which can be clean water, wastewater, cleaning solutions, gas-liquid mixtures, etc. The following explanation uses a floor scrubber as an example, specifically when the first receiving cavity 111 is a wastewater cavity; other equipment can be implemented similarly.

[0039] When the first receiving chamber 111 is a wastewater chamber, it is used to collect wastewater generated when the floor scrubber cleans the surface (floor). When the first receiving chamber 111 is a chamber that combines the functions of a wastewater chamber and a dust box, it is used to collect both dust and wastewater from the surface to be cleaned. In this case, the first receiving chamber 111 is an integrated housing mounted on the floor scrubber. The filter assembly 200 is used to filter dust and debris from the dirty air drawn into the first receiving chamber 111. The filter assembly 200 can be a HEPA filter, or it can be made of filter cotton, activated carbon, or other materials. Considering that the floor scrubber will shake during walking, turning, and obstacle crossing, there is a risk that the sewage in the first receiving chamber 111 may come into contact with the filter component 200 and be adsorbed onto the filter component 200 during the shaking process. After long-term contact with sewage, the filter component 200 is prone to clogging, which greatly reduces the service life of the filter component 200. In severe cases, the sewage may even pass through the filter component 200 and enter the blower duct, causing damage to the operation of the blower. In this invention, by providing a separating component 150, the inflow channel and the outflow channel can be extended, preventing the liquid in the fluid in the first receiving cavity 111 from contacting the filter assembly 200. Furthermore, one end of the separating component 150 is fixed in the first receiving cavity 111 to form an installation end, and the other end is suspended in the first receiving cavity to form a suspended end. The installation end of the separating component is distributed higher than the suspended end. As a result, the top surface of the separating component forms a downwardly extending guide surface. Under the action of the guide surface, the liquid in the fluid can flow back into the first receiving cavity 111, thereby preventing the liquid in the first receiving cavity from contacting the filter assembly and effectively extending the service life of the filter assembly.

[0040] In this invention, please refer to Figure 3 and Figure 7 As shown, the separating component includes a mounting portion 152 with a mounting end X and a guide portion 151 with a suspended end Y. The end of the mounting portion 152 away from the mounting end X is connected to the end of the guide portion 151 away from the suspended end Y. The mounting portion 152 and the guide portion 151 are part of an inflow channel, and the guide portion 151 is also part of an outflow channel; both can be outflow channels. A guide surface H is provided on the guide portion 151 and located within the outflow channel. It is understood that there can be one or more guide portions 151. A single guide portion can be an inclined plate or an inclined curved surface; multiple guide portions can form a stepped, funnel-shaped, or any other possible shape.

[0041] Specifically, the suspended end Y is positioned further away from the first inlet 1111 than the installation end X, so that the connecting port 170 is distributed away from the side of the first inlet 1111. This extends the length of the inflow channel, facilitating gas-liquid separation. Preferably, the vertical projection of the guide portion 151 overlaps with the vertical projection of the first outlet 1112, meaning the guide portion 151 is located directly below the first outlet 1112. Thus, when the floor scrubber shakes, the wastewater in the first receiving cavity 111 cannot contact the filter assembly 200 due to the shielding effect of the guide portion 151, providing better protection for the filter assembly 200. Furthermore, the arrangement of the guide portion 151 directly below the first outlet 1112 makes the overall structure more compact.

[0042] In one embodiment, the guide surface H is a plane that slopes downwards from the mounting end X towards the suspended end Y. The angle of inclination of the guide surface H relative to the horizontal plane ranges from 0° to 90°, preferably from 1° to 5°. If the angle of inclination of the guide surface H is too small, the purpose of fluid backflow will not be achieved. If the angle of inclination of the guide surface H is too large, the opening of the connecting port 170 will be too large, and the fluid in the first receiving cavity 111 can easily enter the outflow channel through the connecting port 170. In this case, the guide part 151 can be regarded as an inclined baffle located below the filter assembly 200. The fluid in the first receiving cavity 111 can only enter the outflow channel from the direction of the connecting port 170 and cannot enter the outflow channel from other directions. Similarly, when the floor scrubber body shakes, the sewage can only enter from the direction of the connecting port 170 and cannot enter the outflow channel from other directions. Thus, the filter assembly 200 can be better protected.

[0043] In this invention, please refer to Figures 8 to 10 As shown, the filter assembly 200 includes a mounting base 210 detachably mounted on the top of the housing body 100 and a filter element unit 220 housed within the mounting base 210. The mounting base 210 has an air inlet 211 at its bottom, allowing gas flowing from the first outlet 1112 to enter the filter assembly 200. The mounting base 210 has an exhaust port 212 on its top and / or side wall, discharging the gas filtered by the filter element unit 220. The filter assembly 200 can also be integrally mounted on the top of the housing or inside the housing. "Integratedly mounted" can be understood as mounting the mounting base 210 and the filter element unit 220 as a single unit. When the filter assembly 200 is integrally mounted on the top of the housing or inside the housing, it can be detachably mounted on the housing body 100 using methods such as snap-fit ​​connections or magnetic connections.

[0044] Further, please refer to Figures 2 to 4 , Figure 7As shown, the top of the box body 100 is recessed downwards to form a groove 160, and the mounting base 210 is disposed within the groove 160. The first outlet 1112 is located at the bottom of the groove 160, which is also the top of the first receiving cavity 111. The first inlet 1111 is located on the side wall of the first receiving cavity 111, and the mounting part 152 is disposed opposite to the first inlet 1111. It can be understood that the first outlet 1112 can also be located on the side wall of the groove 160, and the first inlet 1111 can also be located at the top of the first receiving cavity 111. (See attached image) Figure 3 The hollow arrow represents the flow path of the fluid. The fluid enters the first receiving cavity 111 through the first inlet 1111. When it flows to the mounting part 152, the flow direction changes under the action of the mounting part 152, and then flows along the extension direction of the separation part 150. When it flows to the connecting port 170, the flow direction of the fluid changes again. The gas in the fluid after the flow direction changes flows out of the first receiving cavity 111 along the outflow channel, while the liquid in the fluid flows back to the first receiving cavity along the guide part.

[0045] In this invention, the housing structure further includes a sliding component and a fixing component connected together. Specifically, the mounting base 210 and the groove 160 are slidably connected by the sliding component, and when the mounting base 210 slides into place on the groove 160, the fixing component is used to detachably fix the mounting base 210 in the groove 160.

[0046] Furthermore, the aforementioned sliding assembly includes a first connecting structure 161 and a second connecting structure 213. The first connecting structure 161 and the second connecting structure 213 are slidably engaged, and this slidable engagement serves as a guide and limiter for installation. The first connecting structure 161 and the second connecting structure 213 restrict the degree of freedom of movement of the mounting base 210 in the front, back, left, and right directions. The first connecting structure 161 is disposed on a pair of sidewalls of the groove 160, and the second connecting structure 213 is disposed on the sidewall of the mounting base 210 opposite to the aforementioned sidewalls. One of the first connecting structure 161 and the second connecting structure 213 is a groove, and the other is a slider. The groove extends from the top of the housing body 100 towards the bottom of the housing body 100, allowing the mounting base 210 to be inserted into the groove 160 from top to bottom. Preferably, the groove is an arc-shaped groove, but it can also be a straight line or other types of grooves.

[0047] Furthermore, the aforementioned fixing assembly includes a third connecting structure 216 and a fourth connecting structure 162, which are engaged in a snap-fit ​​configuration. The third connecting structure 216 is located on the side of the mounting base 210 away from the second connecting structure 213, and the fourth connecting structure 162 is located on the side wall of the groove 160 corresponding to the side of the third connecting structure 216. Please refer to [link / reference]. Figure 10 As shown, the third connecting structure 216 includes a bent element 2161 with elastic deformation capability and a first protruding edge 2162 fixed to the bent element 2161 and protruding towards the side wall of the groove 160. Specifically, the bent element 2161 extends from the bottom to the top of the mounting base 210, and the bent element 2161 is inclined towards the side wall of the groove 160, wherein the bottom of the bent element 2161 is fixed to the bottom of the mounting base 210. The fourth connecting structure 162 is a second protruding edge protruding on the side wall of the groove 160, and the first protruding edge 2162 and the second protruding edge are engaged.

[0048] The third connecting structure 216 and the fourth connecting structure 162 have an engaged state and an unlocked state. When the third connecting structure 216 and the fourth connecting structure 162 are in the engaged state, the second protruding edge is located above the first protruding edge 2162, thereby restricting the vertical movement freedom of the mounting base 210, and thus confining the mounting base 210 within the groove 160. When the third connecting structure 216 and the fourth connecting structure 162 are in the unlocked state, the mounting base 210 can be removed from the groove 160. Understandably, the switching between the engaged state and the unlocked state is achieved by moving the bending member 2161. When it is necessary to switch from the engaged state to the unlocked state, press the top of the bending member 2161 and move the bending member 2161 towards the mounting base 210 to disengage the first protruding edge 2162 and the second protruding edge from the engaged relationship.

[0049] In this invention, please refer to Figure 9 As shown, the mounting base 210 is hollow inside, and the filter element unit 220 is disposed inside the hollow cavity of the mounting base 210. The air inlet 211 and the air outlet 212 are respectively connected to the hollow cavity of the mounting base 210. The bottom of the hollow cavity of the mounting base 210 is also provided with a recess 215 for mating with the bottom of the filter element unit 220. The air inlet 211 is located at the bottom of the recess 215. By providing the recess 215, the assembly accuracy and installation convenience of the filter element unit 220 can be improved.

[0050] Please see Figures 9 to 12 As shown, the filter element unit 220 includes a filter element body, a first sealing member 223 disposed at the bottom of the filter element body and surrounding the air inlet 211, and a top block 2213 disposed at the top of the filter element body. The bottom of the filter element body is the air inlet area of ​​the filter element unit 220, and the top of the filter element body is the air outlet area. The first sealing member 223 is located in the recess 215. After the filter element unit 220 is installed onto the mounting base 210, the top block 2213 abuts against the top plate 214 of the mounting base 210, so that the first sealing member 223 is pressed between the bottom of the filter element body and the air inlet 211, thereby improving the sealing performance at the air inlet 211 and allowing all gas to pass through the filter element body.

[0051] The top of the mounting base 210 has an opening, and a top plate 214 is hinged to the top of the mounting base 210. A fifth connecting structure 2141 is provided on the side of the top plate 214 opposite to the hinge side, and this fifth connecting structure 2141 connects the top plate 214 to the mounting base 210. Preferably, the fifth connecting structure 2141 is a snap-fit. The top plate 214 has a closed state (closing the opening) and an open state (opening the opening), and is configured to switch between these states in response to user operation. This allows for convenient replacement of the filter element unit 220 within the mounting base 210. The aforementioned abutment block 2213 also serves a gripping function; when replacing the filter element unit 220, the user can remove it from the mounting base 210 using the abutment block 2213.

[0052] To improve the sealing performance between the opening and the top plate 214, a second sealing element 217 is provided between the opening at the top of the mounting base 210 and the top plate 214. The second sealing element 217 is arranged around the opening for sealing between the opening and the top plate 214. Understandably, the second sealing element 217 can be located on the top plate 214 or at the opening, depending on the actual application. Furthermore, a third sealing element 230 is provided between the mounting base 210 and the first outlet 1112 for sealing. The third sealing element 230 is arranged around the connection between the mounting base 210 and the first outlet 1112 to improve the sealing performance between the mounting base 210 and the first outlet 1112.

[0053] In this invention, please refer to Figure 12 As shown, the filter element body includes a filter element frame 221 and a filter element 222 housed within the filter element frame 221. The top of the filter element frame 221 is the air outlet area of ​​the filter element unit 220, and the bottom of the filter element frame 221 is the air inlet area of ​​the filter element unit 220. The filter element frame 221 is divided into upper and lower parts to facilitate the installation of the filter element 222 within the filter element frame 221. The filter element frame 221 includes a hollow main frame 2211 with an open bottom and a bottom frame cover 2212 covering the bottom opening of the main frame 2211.

[0054] The filter element 222 includes a filter element body 2221 and a perforated partition 2222. The perforated partition 2222 is located closer to the air inlet area than the filter element body 2221. The perforated partition 2222 is used to prevent sharp particulate matter in the gas from damaging the filter element body 2221. The filter element body 2221 can be a material with adsorption and filtration effects, such as HEPA or filter cotton, while the perforated partition 2222 can be a material with the same effect, such as nylon mesh or metal mesh.

[0055] In this invention, please refer to Figure 5 and Figure 6As shown, the main body 100 also has a second receiving cavity 112 inside, which is located outside the first receiving cavity 111 and is used to store cleaning liquid. This cleaning liquid is used to wet the cleaning rollers at the bottom of the floor scrubber. The first receiving cavity 111 has a first center of mass A, and the second receiving cavity 112 has a second center of mass B. The first center of mass A and the second center of mass B are located on the same vertical plane Z. The vertical plane Z is configured to divide the space occupied by the first receiving cavity 111 and the second receiving cavity 112 into a first region Z1 and a second region Z2 with equal media mass. The first region Z1 and the second region Z2 are located on opposite sides of the vertical plane Z.

[0056] The aforementioned equality of medium mass can be understood as follows: the medium mass in the first region Z1 is completely equal to the medium mass in the second region Z2; or, the medium mass in the first region Z1 is approximately equal to the medium mass in the second region Z2; or, the masses in the first region Z1 and the second region Z2 are equal when there is no medium. In this specification, "approximately" can be understood as close to, approximately, or differing from the target value within a predetermined range. Through this method, regardless of how the medium in the first receiving cavity 111 and the medium in the second receiving cavity 112 change, the medium mass on both sides of the vertical plane Z within the housing body 100 remains equal, possessing the advantages of uniform mass distribution and stable centroid distribution.

[0057] Furthermore, the number distribution of the second receiving cavities 112 includes the following cases: first, there is only one second receiving cavity 112; second, there are at least two second receiving cavities 112. When there is only one second receiving cavity 112, the second receiving cavity 112 is distributed in a ring shape around the outer periphery of the first receiving cavity 111. Of course, the second receiving cavity 112 can also be square, elliptical, or other regular or irregular shapes. When there are at least two second receiving cavities 112, the centroid of all the second receiving cavities 112 is the second centroid. To facilitate obtaining the above-mentioned centroid, the second receiving cavities 112 are symmetrically distributed on the outer side of the first receiving cavity 111, and each second receiving cavity 112 is interconnected. When the second receiving cavities 112 are interconnected, the medium height in each second receiving cavity 112 is consistent, thereby making it easier to obtain the above-mentioned centroid. The second receiving cavity 112 is symmetrically distributed on the outside of the first receiving cavity 111 in the following forms: First, the second receiving cavity 112 is distributed on both sides of the first receiving cavity 111 in an axially symmetrical manner; Second, the second receiving cavity 112 is distributed on the outside of the first receiving cavity 111 in a centrally symmetrical manner; Third, the second receiving cavity 112 is distributed on the outside of the first receiving cavity 111 in a rotationally symmetrical manner.

[0058] When there are two second receiving cavities 112, please refer to Figure 5 As shown, two second receiving cavities 112 are distributed on both sides of the first receiving cavity 111 in an axially symmetrical, centrally symmetrical, or rotationally symmetrical manner. In this case, the first receiving cavity 111 and the second receiving cavity 112 are distributed on the same straight line.

[0059] When there are three second receiving cavities 112, in one embodiment, please refer to Figure 10 As shown, the three second receiving cavities 112 are arranged to form an equilateral triangle, with the first receiving cavity 111 located at the center of the equilateral triangle. The center refers to the point where the centroid, orthocenter, incenter, and circumcenter of the equilateral triangle converge. In this case, the three second receiving cavities 112 can be distributed symmetrically or rotationally outside the first receiving cavity 111. In another embodiment, please refer to... Figure 11 As shown, the three second receiving cavities 112 are arranged to form an isosceles triangle, and the first receiving cavity 111 is located at the midpoint of the base of the isosceles triangle. At this time, the three second receiving cavities 112 are distributed symmetrically on the outside of the first receiving cavity 111.

[0060] When there are four second receiving cavities 112, please refer to Figure 12 As shown, four second receiving cavities 112 are arranged to form a square, with the first receiving cavity 111 located at its center of symmetry, which is the intersection of the diagonals of the square. In this case, the second receiving cavities 112 can be arranged outside the first receiving cavity 111 in an axially symmetrical, centrally symmetrical, or rotationally symmetrical manner. It can be understood that when the four second receiving cavities 112 are arranged to form a rectangle, the second receiving cavities 112 are located at the intersection of its diagonals. In this case, the second receiving cavities 112 can be distributed outside the first receiving cavity 111 in an axially symmetrical or centrally symmetrical manner.

[0061] Specifically, please refer to Figure 7 As shown, two adjacent second receiving cavities 112 are connected by a fluid channel 130, which is located inside the housing body 100. This ensures that the distribution of the medium within each second receiving cavity 112 is highly consistent. The fluid channel 130 is preferably located at the bottom of the second receiving cavity 112. It is understood that adjacent second receiving cavities 112 can also be connected via pipes or other connection methods.

[0062] Understandably, the box structure in this invention can be applied to different usage scenarios, as illustrated below.

[0063] The housing structure of this invention can be applied to cleaning equipment. Please refer to [link / reference]. Figure 13 and Figure 14As shown, the cleaning equipment includes a body 300, a brush chamber at the bottom of the body 300, and a cleaning roller 310 inside the brush chamber; a drive wheel located at the bottom of the body 300 for driving the body 300 forward or backward; and a housing structure located inside the body 300, communicating with the brush chamber; wherein the housing structure is as described above. The housing structure in this invention prevents wastewater in the first receiving chamber 111 from contacting the filter assembly 200, effectively extending the service life of the cleaning equipment; furthermore, the housing structure ensures uniform force distribution on the drive wheel, improving the stability and reliability of the cleaning equipment's operation.

[0064] The aforementioned cleaning equipment is a robot capable of performing the required cleaning operations in an environment without human guidance. In this invention, the cleaning equipment can be a sweeping robot, mopping robot, floor scrubber, or similar device. Considering that the cleaning liquid in the second receiving cavity 112 will be consumed during the operation of the cleaning equipment, it is necessary to replenish the second receiving cavity 112 with cleaning liquid periodically. There are two methods for replenishing the second receiving cavity 112: one is manual replenishment; the other is automatic replenishment after docking with an external device. Please refer to [link / reference]. Figure 1 , Figure 5 and Figure 6 As shown, in the case of manual replenishment, the top of the second receiving cavity 112 is provided with a manual filling port 1122 for manual replenishment, which communicates with the second receiving cavity 112. A detachable sealing cap 1123 is provided on the manual filling port 1122 for sealing it. The sealing cap 1123 is preferably made of soft rubber material. After the second receiving cavity 112 is filled with cleaning liquid, the sealing cap 1123 can be directly placed on the manual filling port 1122. Understandably, the sealing cap 1123 can also be made of plastic material. In this case, the sealing cap 1123 can have a threaded, screw-on, or snap-fit ​​connection structure, and the sealing cap 1123 is connected to the manual filling port 1122 through the above connection structure. In the case of automatic replenishment, the second receiving cavity 112 is provided with an automatic filling port (not shown) for automatic replenishment by interfacing with external equipment, which communicates with the second receiving cavity 112. The automatic filling port is provided with a valve (not shown) for controlling the opening and closing state of the automatic filling port.

[0065] In order to know the liquid level in the second receiving cavity 112, in this invention, the top of the second receiving cavity 112 is provided with a pair of second top conductive connecting pieces (not shown) for detecting the highest liquid level in the second receiving cavity 112; the bottom of the second receiving cavity 112 is provided with a pair of bottom conductive connecting pieces 1124 for detecting the lowest liquid level in the second receiving cavity 112; wherein, the cleaning liquid in the second receiving cavity 112 is a conductive medium.

[0066] Considering that if the first receiving cavity 111 is not emptied in time after being fully loaded, it will affect the cleaning effect of the floor scrubber, in this invention, the bottom of the first receiving cavity 111 is provided with a drain port (not shown). The drain port can be divided into a manual drain port for manual drainage and an automatic drain port for automatic drainage. It can be understood that the first receiving cavity 111 can be provided with both a manual drain port and an automatic drain port, or one of them can be selected. When the bottom of the first receiving cavity 111 is provided with a manual drain port communicating with the first receiving cavity 111, a sealing gasket (not shown) for closing the manual drain port can be detachably provided on the manual drain port; when the bottom of the first receiving cavity 111 is provided with an automatic drain port (not shown), the automatic drain port is provided with a valve for controlling the opening and closing state of the automatic drain port, and the automatic drain port is used to connect with external equipment to realize the function of automatic drainage of the first receiving cavity 111.

[0067] In order to detect the highest liquid level in the first receiving cavity 111, a pair of first top conductive connecting pieces 1113 are provided on the top of the first receiving cavity 111. The first top conductive connecting pieces 1113 are configured to detect the highest liquid level in the first receiving cavity 111. The solid-liquid mixture is a conductive medium. When the liquid level in the first receiving cavity 111 is higher than the pair of first top conductive connecting pieces 1113, the pair of first top conductive connecting pieces 1113 are connected under the action of the first medium to realize liquid level detection.

[0068] In this invention, the first top conductive connecting piece 1113, the second top conductive connecting piece, and the bottom conductive connecting piece 1124 have the same structure. The first top conductive connecting piece 1113 will be used as an example for explanation. The first top conductive connecting piece 1113 includes a metal substrate, a positive electrode fin, and a negative electrode fin disposed on the metal substrate. When the liquid level in the first receiving cavity 111 is higher than the positive electrode fin and the negative electrode fin, the positive electrode fin and the negative electrode fin are connected by a first medium, forming a fully loaded electrical signal in the first receiving cavity 111.

[0069] Furthermore, a pressure regulating member 1125 is provided at the top of the second receiving cavity 112. The pressure regulating member 1125 is configured to make the pressure inside the second receiving cavity 112 consistent with the external pressure during liquid discharge or replenishment. The pressure regulating member 1125 is preferably a waterproof and breathable membrane. However, the pressure regulating member 1125 includes, but is not limited to, the above-mentioned waterproof and breathable membrane, and may also be a duckbill valve, etc.

[0070] In this invention, the main body 100 is divided into upper and lower parts, including a hollow base 110 with an open top and an upper cover 120 fixed to the top opening of the base 110. In one embodiment, the base 110 and the upper cover 120 are integrally formed by ultrasonic welding after assembly. The upper cover 120 is provided with the aforementioned pressure regulating component 1125, and a handle 140 is also hinged to the upper cover 120. The handle 140 facilitates the user to remove the main body 100 from the floor scrubber, providing the advantage of easy disassembly and assembly.

[0071] Further, please refer to Figure 6 As shown, a protrusion 141 is provided at the pivot point between the handle 140 and the top cover 120. The handle 140 has an initial state and a pulled state; when the handle 140 is in the initial state, the handle 140 is generally parallel to the upper surface of the top cover 120, and when the handle 140 is in the pulled state, the handle 140 is generally perpendicular to the upper surface of the top cover 120. In this invention, the protrusion 141 is configured to fix or release the case body 100 in response to the change of the handle 140 between the initial state and the pulled state, thereby realizing a detachable connection between the case body 100 and the body 300. Understandably, the body 300 is provided with a groove (not shown) that mates with the protrusion 141; when the handle 140 is in the initial state, the protrusion 141 engages with the groove; when the handle 140 is in the pulled state, the protrusion 141 disengages from the groove.

[0072] In this invention, please refer to Figure 1 As shown, a magnet 180 is also provided on the outer wall of the box body 100, and a Hall sensor (not shown) is provided on the body 300 of the floor scrubber. The Hall sensor works in conjunction with the magnet 180 to sense whether the box body 100 is installed in place.

[0073] The cleaning device of the present invention can be viewed as a structure symmetrical about its axial plane M; see [link to relevant documentation]. Figure 13 As shown, the aforementioned central axis plane M can be understood as a vertical plane distributed along the forward direction of the cleaning equipment, and the drive wheels of the cleaning equipment are symmetrically distributed about the central axis plane M. The housing body 100 is located inside the cleaning equipment body and in the middle of the cleaning equipment body. The first receiving cavity 111 and the second receiving cavity 112 are used to contain fluids, which can be clean water, sewage, cleaning solutions, gas-liquid mixtures, etc. When the first receiving cavity 111 is used as a sewage tank, it is used to contain sewage on the cleaning rollers of the cleaning equipment and dirt swept by the cleaning rollers; the mixture of sewage and dirt is the first medium contained in the first receiving cavity 111. When the second receiving cavity 112 is used as a clean water tank, the clean water tank stores cleaning liquid; the cleaning liquid is the second medium contained in the second receiving cavity 112.

[0074] The first inlet 1111 is used to allow sewage and dirt to enter the first receiving chamber 111; the first outlet 1112 is used to allow gas separated by the guide section to flow out of the first receiving chamber 111. The second receiving chamber 112 is provided with an outlet 1121 for liquid to exit from the second receiving chamber 112. The second receiving chamber 112 delivers cleaning liquid to the cleaning roller of the cleaning equipment through the outlet 1121 to wet the cleaning roller. The forward direction of the cleaning equipment is defined as forward, the backward direction as rearward, and the two sides of the forward and backward directions of the cleaning equipment are defined as left and right directions. During the forward movement of the cleaning equipment, the first receiving chamber 111 continuously draws in sewage from the cleaning roller and dirt from the ground, while the second receiving chamber 112 continuously delivers cleaning liquid to the cleaning roller. During this process, the mass of the first medium in the first receiving chamber 111 and the mass of the second medium in the second receiving chamber 112 are constantly changing. Commercially available box structures cannot guarantee that the mass of the medium in the box structures on the left and right sides of the central axis M is always equal. When cleaning equipment is running, the different media masses on both sides of the central axis surface M exert different forces on the drive wheels, resulting in poor operational stability. The housing structure in this invention, during installation, only needs to ensure that its vertical plane Z coincides with the central axis surface M of the floor scrubber. This guarantees that the media mass within the housing body 100 on both sides of the central axis surface M remains equal, effectively solving the problem of poor operational stability caused by inconsistent mass on both sides of the central axis surface M.

[0075] The above is only one specific embodiment of the present invention, and any improvements made based on the concept of the present invention shall be considered within the scope of protection of the present invention.
