Description

Technical Field

[0001] This invention relates to the field of cleaning technology, and in particular to an integrated water tank that can separate cleaned water from contaminants. Background Technology

[0002] Current floor cleaning tools are generally categorized into two branches: air-jet cleaning, represented by vacuum cleaners, and water-jet cleaning, represented by floor scrubbers. However, due to the limitations of their working principle, vacuum cleaners cannot clean some stubborn debris and stains that are firmly attached to the floor. Water-jet floor scrubbers, on the other hand, use a motor to drive a cleaning drum that wipes the floor. The cleaning drum typically uses a sponge-like structure, and the scrubber is also equipped with a water supply system and a water tank to clean the drum, thus achieving a perfect cleaning of the floor. To clean the drum, a closed cleaning space connected to the water supply system is usually set up to clean specific sections of the drum, providing clean water for rinsing the drum before the wastewater is pumped away.

[0003] Due to limitations in their underlying technology, existing "air-dust circulation" floor scrubbers can only use water tank systems with completely separate clean water and wastewater tanks. Most existing "water-dust circulation" floor scrubbers use the traditional separate design for clean water and wastewater tanks, while some adopt an integrated design. The integrated design allows users to add clean water while emptying wastewater, making it more convenient to use.

[0004] Chinese patents CN215937253U and CN218128365U disclose a water tank and cleaning tool. The water tank has an internal partition dividing it into a clean water zone and a wastewater zone, each equipped with a water level detection device. This combined clean water and wastewater zones significantly reduces the tank's size, allowing for a compact and lightweight cleaning tool design. Furthermore, the water level detection devices in both zones enable users to promptly know when the clean water is depleted or the wastewater is full, improving cleaning effectiveness.

[0005] Chinese patent CN215016831U discloses a water tank and a cleaning device. The cleaning device includes a body, and the water tank includes a clean water tank, a wastewater tank, a locking sleeve, and a guide cover. The body has a water tank mounting groove, and the top of the water tank mounting groove has a water outlet. The water tank includes a clean water tank and a wastewater tank. The clean water tank has a first water inlet, and the wastewater tank has a second water inlet. The clean water tank and the wastewater tank are connected by a locking sleeve and installed in the water tank mounting groove. The guide cover includes a first cover, a second cover, and a sliding groove. One end of the sliding groove is connected to the first cover, and the other end is connected to the second cover. The first cover covers the first water inlet, and the second cover covers the second water inlet. The second cover has a water inlet corresponding to the water outlet. During water tank installation, the water outlet is pushed upward by the sliding groove until the water outlet aligns with the water inlet, thus embedding the water outlet into the water inlet. This solves the technical problem that the water tank needs to be installed repeatedly, causing wear and tear on the installation parts of the machine and the water tank, resulting in a poor user experience. (Paragraph 18 of the specification is mentioned in conjunction with...) Figure 1 , Figure 2 , Figure 3 It can be seen that the guide cover has a relatively complex structure that directly covers the first and second water inlets.

[0006] Chinese patents CN307180807S and CN307349603S each disclose an integrated clean water and wastewater tank for a sweeping and mopping integrated cleaning device.

[0007] Chinese patent CN114468899A discloses an integrated clean water and wastewater tank, comprising a tank body with a sealed cavity. The tank body contains a clean water chamber and a wastewater chamber with variable storage space. The clean water chamber has an outlet connected to a first water pump, and the wastewater chamber has an inlet connected to a second water pump. Because the tank body has flexible partitions, the clean water and wastewater chambers, which serve as storage spaces for both clean and wastewater, can store a larger amount of clean or wastewater in a smaller volume, extending the usage time with a single fill. Furthermore, each independent chamber can be divided into multiple interconnected partitions, preventing liquid sloshing during use and improving the user experience.

[0008] In existing technologies, both separate and integrated water tank systems require complex piping inside and outside the clean water and wastewater tanks to ensure their coordinated operation. While some solutions allow the tank lid to cover both tanks simultaneously, the clean water outlets are often located at low elevations and far from the wastewater return outlets, making manufacturing and maintenance cumbersome. The low elevation of the clean water outlet also increases the risk of leaks, especially in systems with additional power connections, which can lead to short circuits. Furthermore, the complex coordination between the clean water and wastewater tanks, coupled with the intricate piping inside and outside, results in low overall space utilization and makes individual maintenance of either tank difficult. Some integrated water tank systems, while separating the clean water and wastewater chambers internally, still maintain a single, integrated structure, making it impossible to remove and replace the clean water or wastewater tanks separately for maintenance or replacement. Summary of the Invention

[0009] The main technical problem solved by this invention is to provide an integrated water tank that can be cleaned and separated from contaminants, which simplifies the internal pipeline connection of the water tank system, improves the space utilization of the entire water tank system, and improves the efficiency of the manufacturing process and the maintenance of spare parts.

[0011] The clean water tank contains and outputs clean water for cleaning tools. It has a water outlet on its top wall and a water pump connector on its bottom inner wall.

[0012] A wastewater tank for collecting wastewater from cleaning tools; its sides and bottom are enclosed, with only the top open.

[0013] The water tank cover can simultaneously cover the clean water tank and the wastewater tank from the top. It is provided with a clean water outlet and a wastewater inlet, and is also directly or indirectly connected to a water pumping pipe placed in the clean water tank. The water pumping pipe connects the clean water outlet and the water pumping connector.

[0014] Based on the above technical solution, the present invention can be further improved as follows.

[0015] In one embodiment, the opening extends horizontally outward from one side of the side wall as a protrusion, which covers the entire top wall of the clean water tank. A portion of the tank lid covers the entire protrusion, and an upper interface portion and a lower interface portion extend from the upper and lower sides of the middle of the protrusion, respectively. The lower interface portion abuts against the water outlet, and the upper interface portion extends into the tank lid and communicates with the clean water outlet.

[0016] In one embodiment, an annular weir extends upward from the upper side of the top wall to frame the outlet, thereby achieving a seal with the lower wall surface of the eaves.

[0017] In one embodiment, the annular weir is located on the outer edge of the top wall, and the top wall and the eaves are provided with through holes that connect to the outside atmosphere and the clean water tank in sequence.

[0018] Based on the above technical solution, the present invention can be further improved as follows.

[0019] In one embodiment, a vertical plate extends upward from one side of the top wall, and the front of the plate facing the sewage tank can slide up and down to abut against a vertical side wall of the tank cover and the front end of the eaves.

[0020] In one embodiment, after the water tank cover closes the clean water tank and the wastewater tank, the side wall of the water tank cover completely abuts against the front of the entire upright plate, and the side wall of the water tank cover and the upright plate are at the same height.

[0021] Based on the above technical solution, the present invention can be further improved as follows.

[0022] In one embodiment, a gripping mechanism is detachably connected to the back of the upright plate.

[0023] In one embodiment, a water electrolysis module is provided at the bottom of the clear water chamber, and a directional channel is provided between the water electrolysis module and the water pump connector to ensure that the water that has just been electrolyzed and disinfected is directly pumped out of the clear water tank.

[0024] In one embodiment, the integrated water tank capable of separating clean and contaminant also includes an electrical connection component that is connected to the access end of the water electrolysis module and can draw power from outside the water tank.

[0025] In one embodiment, the integrated water tank with separable clean and dirty water further includes a water tank bottom cover assembly that closes the clean water tank and / or the dirty water tank from the bottom.

[0026] In one embodiment, the water tank bottom cover assembly seals the clean water tank from the bottom, and the water electrolysis module is mounted on the side of the water tank bottom cover assembly facing the clean water tank with its access end passing through the clean water tank sealing layer of the water tank bottom cover assembly.

[0027] In one embodiment, the water pump is mounted on the bottom cover assembly of the water tank.

[0028] Based on the above technical solution, the present invention can be further improved as follows.

[0029] In one embodiment, the electrical connection member is an adapter box with a cable outlet having two flexible electrodes electrically connected to the water electrolysis module via a wire harness.

[0030] In one embodiment, the water tank bottom cover assembly includes a water tank bottom cover frame, the upper surface of which encloses the clean water tank, and the lower surface of which encloses a wiring cavity for connecting the water electrolysis mold access terminal.

[0031] In one embodiment, a portion of the upper surface of the water tank bottom cover frame encloses the clean water tank, while the upper surface area not used to cover the clean water cavity is provided with a support platform for installing the adapter box. The support platform is provided with a cable passage port directly opposite the outlet port.

[0032] In one embodiment, one end of the wire harness is connected to the elastic electrode, and the other end passes through the outlet and through-hole in the connection cavity to the water electrolysis mold access end for detachable connection.

[0033] In one embodiment, the water tank bottom cover assembly further includes a removable cover for closing the wiring cavity.

[0034] Based on the above technical solution, the present invention can be further improved as follows.

[0035] In one embodiment, both the side wall of the clean water tank and the side wall of the wastewater tank are flat, and the two flat side walls can slide against each other.

[0036] In one embodiment, the clean water tank and the wastewater tank are respectively provided with grooves or ribs on the two side walls that abut against each other, and the ribs can slide up and down in the grooves.

[0037] This invention provides an integrated water tank with separate clean and dirty water components, including a clean water tank, a dirty water tank, and a tank cover. The clean water tank holds and outputs clean water to cleaning tools, with a water outlet on its top wall and a pump connector on its bottom inner wall. The dirty water tank collects the dirty water output by the cleaning tools, with its perimeter and bottom walls closed, and only its top open. The tank cover can simultaneously close the clean water tank and the dirty water tank from the top, and has a clean water outlet and a dirty water inlet. It is also directly or indirectly connected to a pump pipe placed in the clean water tank and communicating with the clean water outlet, with the other end of the pump pipe connected to the pump connector. Because the clean water outlet and dirty water inlet are located on the tank cover and are far away from the power supply interface of the water tank, short circuits between the power supply interfaces caused by water tank leakage can be avoided to the greatest extent. At the same time, the clean water outlet and dirty water inlet integrated on the tank cover are close to each other, which facilitates the connection and maintenance of external pipelines for the water tank, facilitates production organization, and allows consumers to easily maintain it themselves.

[0038] The beneficial effects of this invention are as follows: Firstly, the water tank cover can simultaneously close the clean water tank and the wastewater tank from the top, making the overall assembly and maintenance of the water tank more convenient. Secondly, the clean water outlet and wastewater inlet on the water tank cover are located close to each other, facilitating the connection and maintenance of external pipelines, simplifying production organization, and allowing consumers to easily maintain the tank themselves. Thirdly, the clean water outlet and wastewater inlet on the water tank cover are located far from the power supply interface of the water tank, minimizing the risk of short circuits between the power supply interfaces caused by water tank leaks.

[0078] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0079] See Figures 1 to 3 , Figures 8 to 13 as well as Figure 15This invention provides an integrated water tank with separate clean and dirty water components, comprising a clean water tank 1, a dirty water tank 2, and a tank cover 3. The clean water tank 1 contains and outputs clean water to cleaning tools. The top wall 101 of the clean water tank has an outlet 1014, and the inner bottom wall of the clean water tank is connected to a suction connector 15. The dirty water tank 2 collects the dirty water output from the cleaning tools. The peripheral and bottom walls of the dirty water tank are closed, with only the top of the dirty water tank having an opening 201. The tank cover 3 can simultaneously cover the clean water tank 1 and the dirty water tank 2 from the top. The tank cover 3 has a clean water outlet 31 and a dirty water inlet 32, and the tank cover 3 is also directly or indirectly connected to a suction pipe 14 placed in the clean water tank, which connects the clean water outlet 31 and the suction connector 15.

[0080] In this embodiment, the water tank cover 3 can simultaneously cover the clean water tank 1 and the sewage tank 2, which can improve the overall maintainability of the water tank. The clean water outlet 31 and sewage inlet 32 ​​on the water tank cover 3 are close to each other, which facilitates the connection and maintenance of external pipelines of the water tank, facilitates production organization, and also makes it easy for consumers to perform simple maintenance themselves.

[0081] Specifically, in the embodiments shown in the accompanying drawings, as Figures 1-3 As shown, the integrated water tank with separate clean and dirty water includes a clean water tank 1, a dirty water tank 2, and a water tank cover 3. The clean water tank 1 and the dirty water tank 2 abut against each other through their respective flat side walls. The water tank cover 3 can cover the clean water tank 1 and the dirty water tank 2 from the top simultaneously using its stepped bottom surface.

[0082] See Figure 3 , Figure 8 , Figure 10 , Figure 13 In some embodiments, the symmetrical mid-section of the water tank cover 3 is shaped like an "η". The short hook at the front of the "η" shape, i.e., the first stepped surface (not shown in the figure), is used to directly or indirectly close the outlet 1014 of the top wall 101 of the clean water tank. The area around the long hook at the back of the "η" shape, i.e., the second stepped surface (not shown in the figure), is used to close the opening 201 of the sewage tank. The long hook at the back of the "η" shape is a Hall sensor (not shown in the figure) that can be detachably installed on the water tank cover, used to determine whether the sewage in the sewage tank should be emptied in time.

[0083] See Figures 1-3 , Figures 8-13In some embodiments, the clean water tank 1 includes a clean water tank body assembly 10, which includes a clean water tank body 100 and a top wall 101. The clean water tank 1 abuts against the clean water tank 2's clean water tank body 200a via a planar side wall 100a. The symmetrical mid-section of the clean water tank 1 presents an L-shape. The peripheral wall (not shown in the figure) and bottom wall (not shown in the figure) of the clean water tank 1 are closed. Only the top wall 101 of the clean water tank 1 is provided with an outlet 1014 and an atmospheric communication docking hole 1013. An annular weir 1011 extends upward on the top wall 101. Slide grooves or ribs 100a1 are provided on the two vertical edges of the planar side wall 100a. Correspondingly, ribs or slide grooves 200a1 are provided on the two vertical edges of the clean water tank 2's planar side wall 200a, which facilitates the sliding of the clean water tank 1 and the wastewater tank 2. The upper part of the L-shape of the clean water tank 1 is a column with a single cross-section. The bottom of the clean water tank 1 is also equipped with a water pump connector 15. One end of the water pump connector has a hole facing the bottom of the water tank (not shown in the attached drawing), and the other end is connected to a water pump pipe 14. The other end of the water pump pipe is connected to the clean water outlet 32 ​​of the water tank cover 3. A filter device is also provided around the water pump connector 15 (not shown in the attached drawing).

[0084] See Figures 1-3 , Figure 9 , Figure 12 In some embodiments, the sewage tank 2 includes a sewage tank body assembly 20, which includes a sewage tank body 200 and a bottom wall 202. The sewage tank 2 abuts against the planar side wall 100a of the clean water tank 1 through the planar side wall 200a. The symmetrical mid-section of the sewage tank 2 presents an inverted "L" shape. The peripheral wall (not shown in the figure) and the bottom wall 202 of the sewage tank 2 are closed, with only the top of the sewage tank 2 having an opening 201. The bottom wall 202 is also provided with a guide block 2021 for cooperating with the clean water tank 1. Slide grooves or ribs 200a1 are also provided on the two vertical edges of the planar side wall 200a. Correspondingly, ribs or slide grooves 100a1 are also provided on the two vertical edges of the planar side wall 100a of the clean water tank 1, so as to facilitate the vertical sliding of the sewage tank 2 and the clean water tank 1. The lower part of the inverted "L"-shaped sewage tank is a column with a single cross-section. A protruding eave 21 extends horizontally outward from the side wall of the open end 201. The protruding eave 21 includes a body 210, which completely covers the entire top wall 101 of the clean water tank. The first stepped surface of the tank cover 3 (not shown in the attached diagram) covers the entire protruding eave 21. An upper interface 211 and a lower interface 212 extend from the upper and lower sides of the middle of the protruding eave body 210, respectively. The lower interface 212 abuts against the clean water tank outlet 1014, and the upper interface 211 extends into the tank cover 3 and communicates with the clean water outlet 32. The lower surface of the protruding eave 21 and the top wall 101 are sealed by a pressing annular weir 1011. The tank cover 3 indirectly connects to the water pump 14 in the clean water tank through the upper interface 211 and lower interface 212 of the protruding eave 21. The water pump 14 connects the clean water outlet 31 and the water pump connector 15.

[0085] See Figure 6 , Figure 7 In some embodiments, the middle of the cantilever body 210 is directly configured with a through hole for the water pump 14 to pass through. This allows the water pump to pass directly through the outlet 1014 and the through hole in the middle of the cantilever body 210, extending into the water tank cover 3 and connecting to the clean water outlet 32. The water tank cover 3 is directly connected to the water pump 14 in the clean water tank through the through hole in the middle of the cantilever 21. The water pump 14 connects the clean water outlet 31 and the water pump connector 15. When maintenance of the clean water tank 1 is required, the water tank cover 3 can be opened directly, the water pump 14 straightened, and then the end of the water pump inserted into the water tank cover pulled out, thus achieving complete separation of the clean water tank 1 from the water tank cover 3.

[0086] See Figure 9 , Figure 10 , Figure 12 , Figure 13 In some embodiments, the groove or rib 200a1 of the sewage tank 2 is first aligned with the rib or groove 100a1 of the clean water tank 1. The flat sidewall 200a of the sewage tank 2 is then slid downwards on the flat sidewall 100a of the clean water tank 1, allowing the guide block 2021 of the bottom wall 202 of the sewage tank to extend into the guide opening 1021 on the clean water tank 1. The downward sliding continues until the lower surface of the eaves 21 abuts against the annular weir 1011 of the top wall 101. Screws are driven into the blind hole connecting studs 1012 of the top wall 101 at the fixing hole 214 of the eaves body 210. After tightening and compaction, the lower surface of the eaves 21 and the top wall... 101 forms a seal between the two by pressing the annular weir 1011. At the same time, the atmospheric connection hole 1013 of the top wall 101 and the atmospheric connection port 213 of the eaves 21 are also connected and connected. After the water tank cover 3 is closed, the air in the clear water tank 1 can still be connected to the outside atmosphere through the atmospheric connection hole 1013, the atmospheric connection port 213, the gap between the first step surface of the water tank cover (not shown in the attached figure) and the eaves 21. Thus, the water level in the clear water tank can drop as the clear water is lost during use, and the clear water tank will not be unable to dispense clear water due to the pressure difference between the inside and outside of the water tank.

[0087] In some further improved embodiments, such as Figure 10 , Figure 12 , Figure 14 As shown, a vertical plate (not shown in the attached figure) extends vertically upward on the side where the top wall 101 intersects with the planar side wall 100a. This plate can slide up and down to abut against the front 100b of the sewage tank 1 and the front end of the vertical side wall (not shown in the attached figure) and the eaves 21 of the water tank cover 3.

[0088] In some further improved embodiments, such as Figure 1 , Figure 3 , Figure 8 , Figure 11 As shown, after the water tank cover 3 covers the clean water tank 1 and the sewage tank 2, the side wall of the water tank cover completely abuts the front of the entire upright plate 100b. The side wall of the water tank cover and the upright plate are at the same height, so as to make better use of the space in the height direction of the entire water tank.

[0089] In some further improved embodiments, such as Figures 1-15 As shown, the clean water tank 1 is also provided with an L-shaped support surface 102 that abuts against the sewage tank 2 from the top and bottom. The L-shaped support surface 102 is provided with a guide opening 1021 that cooperates with the guide block 2021, so as to increase the volume of the clean water tank and appropriately reduce the volume of the sewage tank within a limited space.

[0090] In some further improved embodiments, such as Figure 3 , Figure 4 , Figure 9 , Figure 10 , Figure 16 As shown, a gripping mechanism 11 is detachably connected to the back of the upright plate. The gripping mechanism 11 includes a panel 110, a fastener 111, and a spring 112 that elastically abuts against the fastener. The panel 110 is fixed to the upright plate by a fixing stud 1101. The fastener 111 is engaged between the panel 110 and the upright plate. The top of the fastener is provided with a locking tongue 1111 that can elastically extend out of the top of the panel 110. Pressing down on the fastener 111 compresses the spring 112, which allows the locking tongue 1111 to retract below the top of the panel 110. After the water tank is installed in place, the force pressing on the fastener 111 is released, and the locking tongue 1111 extends to complete the engagement and fixation of the water tank on the cleaner body.

[0091] In some further improved embodiments, such as Figure 16 As shown, the upper part of the water tank, which is slightly lower than the gripping mechanism 11, can be set in a recessed shape to form a recess 1001. The recess 1001, together with the gripping mechanism 11, can give the user a better grip on the water tank.

[0092] In some further improved embodiments, such as Figure 3 , Figure 5 , Figure 8 , Figure 10 , Figure 13As shown, a water electrolysis module 13 is installed at the bottom of the clean water tank 1. A directional channel (not shown in the attached diagram) is provided between the water electrolysis module 13 and the water pump connector 15 to ensure that the water that has just been electrolyzed and disinfected is directly pumped out of the clean water tank 1 without being diluted by the whole tank of clean water, thus improving the efficiency of electrolysis disinfection. The water electrolysis module 13 includes an electrolysis module housing 131, an electrolysis plate 132, an indicator LED light 133, and an electrode connector 134. The electrolysis plate 132 and the indicator LED light 133 are installed inside the electrolysis module housing 131 through the internal structure of the electrolysis module housing 131. The electrode connector 134 enables a waterproof connection for the electrolysis module 13 to draw power from the outside. When water flows through the electrolysis plate 132, the electrolysis plate 132 can electrolyze the water into effective disinfecting components under the action of the electric field. The indicator LED light 133 is used to indicate the current working status of the electrolysis module 13.

[0093] In some further improved embodiments, such as Figures 2-15 As shown, the integrated water tank that can separate clean and dirty water also includes an electrical connection component that connects to the access end of the water electrolysis module and can draw power from outside the water tank.

[0094] In some further improved embodiments, such as Figure 3 , Figure 5 , Figure 13 As shown, the electrical connection component is a junction box 4 with two elastic electrodes (not shown in the figure) and a wire outlet (not shown in the figure). The water electrolysis module 13 is electrically connected to the elastic electrodes by a wire harness (not shown in the figure).

[0095] In some further improved embodiments, such as Figure 3 , Figure 5 , Figure 13 As shown, the adapter box 4 includes a front shell 41 and a bottom shell 42 that are interlocked. An electrode cap 43, which is abutted by a spring 45, is elastically clamped between the front shell 41 and the bottom shell 42. After the water tank is installed into the cleaner, the electrode cap 43 can maintain a stable electrical connection with the power supply interface of the cleaner body (not shown in the attached figure) under the elastic support of the spring 45.

[0096] In some further improved embodiments, the integrated water tank with separate clean and dirty water also includes a water tank bottom cover assembly 12, which closes the clean water tank 1 and the dirty water tank 2 from the bottom.

[0097] In some further improved embodiments, the tank bottom cover assembly 12 closes the sewage tank 2 from the bottom.

[0098] In some further improved embodiments, such as Figure 1 , Figure 3 , Figures 5-13As shown, the integrated water tank with separate cleaning and contamination also includes a water tank bottom cover assembly 12, which closes the clean water tank 1 from the bottom. The water tank bottom cover assembly 12 includes a water tank bottom cover middle frame 120, the upper surface of which closes the clean water tank 1, and the lower surface of which forms a wiring cavity for the connection of the water electrolysis mold 13 (not shown in the figure).

[0099] In some further improved embodiments, such as Figure 13 , Figure 15 As shown, a portion of the upper surface of the water tank bottom cover frame 12 encloses the clean water tank 1, while the upper surface area not used to enclose the clean water tank 1 is provided with a support platform for installing the adapter box 4 (not shown in the attached figure). The support platform is provided with a cable passage (not shown in the attached figure) that is directly opposite the cable outlet (not shown in the attached figure).

[0100] In some further improved embodiments, such as Figure 15 As shown, the water tank bottom cover assembly 12 also includes a removable cover 121 for sealing the wiring cavity (not shown in the figure).

[0101] In some further improved embodiments, such as Figure 1 , Figure 9 , Figure 12 , Figures 14-16 As shown, the other side walls of the non-planar side wall 100a of the clean water tank 1 are provided with water inlet flaps 103, which allows users to easily fill the clean water tank 1 without having to open the water tank cover 3.

[0102] In some further improved embodiments, all the internal structures of the adapter box 4 are further compressed into the wiring cavity of the water tank bottom cover assembly 12, which can further increase the volume of the sewage tank without increasing the overall volume of the water tank.

[0103] It should be noted that the shape of adapter box 4 does not have to be... Figures 1-15 The hexahedral shape shown is not the only one that can achieve the main design concept of this application. Other regular shapes such as cylindrical, spherical, tubular, conical, and tetrahedral shapes can also achieve the same result, as long as the two elastic electrodes can be stably connected to the power interface of the cleaner body. These will not be elaborated on here.

[0104] It should also be noted that the connection between the clean water tank 1, the wastewater tank 2, the tank cover 3, and the adapter box 4 is not entirely limited to... Figures 1-14 The four components shown are arranged in a form that completely fills the space. Of course, we can also make trade-offs in the corresponding space according to the other requirements of the water tank and the cleaner body, that is, deliberately hollow out certain spaces. In order to adapt to the cooperation with other parts of the cleaner body, all of these solutions reflect the main design ideas of this application, which will not be elaborated here.

[0105] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification.
