Description

[0001] This application is a divisional application of Chinese Patent Application No. 202310448901.6 entitled "A Bottom Cover Assembly and an Integrated Water Tank", the contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of cleaning technology, and more particularly to a bottom cover assembly and an integrated water tank for cleaning tools. Background Technology

[0003] 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.

[0004] 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.

[0005] 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. The water tank provided in this application combines the clean water and wastewater zones, significantly saving space and 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.

[0006] Chinese patents CN217592757U and CN217524951U disclose an electrolysis component, a storage tank, and a cleaning device. The electrolysis component is used in a storage tank, with a valve body assembly disposed at the bottom opening of the storage tank. The electrolysis component includes a support assembly and at least two electrodes. The support assembly includes a mounting structure and a conductive structure. At least one circumferential side of the mounting structure has a notch for accommodating the valve body assembly. At least two electrodes are disposed on the mounting structure and electrically connected to the conductive structure. The electrolysis component provided by this invention, when installed in the storage tank, allows the valve body assembly to be accommodated within the notch of the electrolysis component, enabling the electrolysis component to be closer to the bottom opening of the storage tank, thereby lowering the electrolyzable liquid level and increasing electrolysis efficiency.

[0007] In existing technologies, both split-type and integrated water tank systems incorporate a water electrolysis module inside the tank to sterilize and disinfect the water used for floor cleaning. The electrolysis module's power-taking structure and water outlet are located on the periphery and bottom walls of the water tank, respectively, which are very close to each other. When the water tank is removed, unused water inevitably drips along the water outlet into the corresponding cavity of the cleaning tools. Because the power-taking electrodes are positioned only slightly above the lowest point of the tank, the leaking water can easily cause short circuits between the electrodes of the water electrolysis module. If a separate water output pipe is added to the water circulation path... Adding a water electrolysis module places higher demands on its size and the corrosion resistance of the corresponding pipelines. Furthermore, integrating the water electrolysis module into the water tank presents a significant challenge, as the tank requires frequent disassembly for wastewater removal and clean water replenishment. Achieving rapid and stable electrical connection and disconnection for the module is a difficult problem to overcome. Additionally, ensuring the waterproofing and ease of replacement and maintenance of the power supply wiring harness and terminals, while maintaining the airtightness of the water tank system, also requires further improvement. Summary of the Invention

Simultaneously, the power supply access device in the bottom cover assembly ensures complete insulation between the water tank and the power-drawing electrodes of the water electrolysis module, while also guaranteeing a certain degree of maintainability for the water electrolysis module's connection. This facilitates production organization and allows consumers to easily replace the water electrolysis module themselves.

The top of the clean water tank body is provided with a top wall, an outlet, an atmospheric communication connection hole, and an annular weir extending upward from the top wall.

[0034] In one or more alternative embodiments, the symmetrical mid-section of the clean water tank is in the shape of an "L" and the bottom of the clean water tank body is closed by a bottom cover assembly. Slide grooves or ribs are provided on the two vertical edges of the planar sidewall. Correspondingly, ribs or slide grooves are provided on the two vertical edges of the planar sidewall of the sewage tank, so as to facilitate the upper and lower sliding of the sewage tank and the clean water tank.

[0035] In one or more alternative embodiments, the upper part of the L-shaped clean water tank is a column with a single cross-section, and the bottom of the clean water tank is also provided with a water pump connector.

[0042] This invention provides a bottom cover assembly and an integrated water tank including the bottom cover assembly. The bottom cover assembly is used to seal the bottom of the integrated water tank, which includes a clean water tank and a wastewater tank. The bottom cover assembly includes: a power supply connection device for connecting the water electrolysis module built into the clean water tank to an external power supply interface of the water tank; a bottom cover frame, the upper surface of which seals the clean water tank and / or the wastewater tank, and the lower surface of which encloses a wiring cavity for the connection of the power supply connection device. The lower surface of the frame includes a load-bearing ring rib to support the weight of the integrated water tank, and the power supply connection device is installed on the upper or lower surface of the frame. Because the clean water outlet on the water tank cover is far from the power supply connection device of the electrolysis module on the bottom cover, and the clean water outlet is drawn by a negative pressure pump located outside the water tank and placed on the cleaning tool body, the separation of the clean water outlet from the negative pressure pump's water supply line when the water tank is removed will only cause a small amount of water remaining at the clean water outlet on the water tank cover to flow back into the clean water cavity. This can minimize the risk of short circuits in the power supply connection device of the water electrolysis module caused by water tank leakage. Meanwhile, the power access device configured on the bottom cover ensures complete insulation between the power electrodes of the water tank and the water electrolysis module, while also ensuring a certain degree of maintainability of the water electrolysis module connection. This facilitates production organization and allows consumers to replace the water electrolysis module themselves.

[0043] The beneficial effects of this invention are as follows: Firstly, the power supply device configured on the bottom cover assembly is located away from the clean water outlet on the water tank cover, which avoids short circuits in the power supply device of the water electrolysis module caused by water tank leakage when the water tank is removed. Secondly, the power supply device configured on the bottom cover assembly ensures complete insulation between the water tank and the power supply electrodes of the water electrolysis module, while also ensuring a certain degree of maintainability for the water electrolysis module connection, facilitating production and allowing consumers to replace the water electrolysis module themselves. Thirdly, the bottom cover assembly further enhances the ability of the clean water tank and wastewater tank to retain leaking water even if bottom leakage occurs, adding an extra barrier and making it less likely for leaked water to cause other harmful or undesirable effects. Finally, the integrated water tank with this bottom cover assembly has high configurability and maintainability, allowing users to maintain and flexibly upgrade each component according to their actual usage.

[0070] 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.

[0071] Firstly, see Figures 1 to 17This invention provides a bottom cover for an integrated water tank for cleaning tools. The integrated water tank includes a clean water tank 1, a wastewater tank 2, a tank cover 3, and a bottom cover 4. The tank cover 3 simultaneously covers both the clean water tank 1 and the wastewater tank 2 from the top. The tank cover 3 has a clean water outlet 31 and is connected to a suction pipe 14 placed in the clean water tank 1 and communicating with the clean water outlet 31. A water electrolysis module 13 is located at the bottom of the clean water tank 1, and a suction connector 15 connected to the suction pipe 14 is located at the same horizontal level to ensure that the water, after electrolysis and disinfection, is directly drawn out of the tank. The bottom cover 4 of the integrated water tank seals the bottom of the integrated water tank and includes a power access device 41 and a bottom cover assembly 42. The power access device 41 electrically connects the water electrolysis module 13 built into the clean water tank 1 to an external power supply interface. The water electrolysis module has a waterproof access end (not shown in the attached drawings). The bottom cover assembly 42 includes a bottom cover frame 420 and a protective cover 421. The bottom of the clean water tank 1 and / or the sewage tank 2 is enclosed on the upper surface of the bottom cover frame 420, and a power supply access device 41 is installed on the upper or lower surface of the bottom cover frame 420.

[0072] In this embodiment, the bottom cover 4 seals the bottom of the integrated water tank, further enhancing the ability of the clean water tank 1 and the wastewater tank 2 to contain leaking water even if bottom leakage occurs. With this additional barrier, the leaked water is less likely to cause other harmful or undesirable effects. On one hand, the electrolysis module power access device 41 configured on the bottom cover 4 is located away from the clean water outlet 31 on the water tank cover 3, preventing short circuits in the power access device 41 caused by water tank leakage when the water tank is removed. On the other hand, the power access device 41 configured on the bottom cover 4 ensures complete insulation between the water tank and the power electrodes of the water electrolysis module 13, while also ensuring a certain degree of maintainability for the water electrolysis module, facilitating production and allowing consumers to replace the water electrolysis module themselves.

[0073] Specifically, in the embodiments shown in the accompanying drawings, as Figures 1-10 , Figure 13 As shown, the clean water tank 1 and the wastewater tank 2 abut against each other through their respective flat sidewalls. The tank cover 3, with its stepped bottom surface, can simultaneously cover both the clean water tank 1 and the wastewater tank 2 from the top. The symmetrical mid-section of the 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 attached diagram), is used to close the top wall of the clean water tank (not shown in the attached diagram). The area around the long hook at the back of the "η" shape, i.e., the second stepped surface (not shown in the attached diagram), is used to close the opening of the wastewater tank (not shown in the attached diagram). The long hook at the back of the "η" shape is a detachable Hall sensor (not shown in the attached diagram) used to determine whether the wastewater in the wastewater tank should be emptied in time. A Hall sensor 16 is installed at the bottom of the clean water tank 1 to determine whether the clean water in the clean water tank should be used up.

[0074] See Figures 1 to 11In some embodiments, the clean water tank 1 includes a clean water tank body 10, a handle assembly 11, and a partial bottom cover 4 for closing the bottom of the clean water tank body 10. The bottom of the clean water tank body 10 is open, and an annular protrusion 10a extends downward from the bottom of the peripheral wall of the clean water tank body (not shown in the figure). The top of the clean water tank body 10 is provided with a top wall, on which is provided a water outlet (not shown in the figure), an atmospheric communication connection hole (not shown in the figure), and an annular weir (not shown in the figure) extends upward from the top wall. The clean water tank 1 abuts against the flat sidewall of the wastewater tank 2 (not shown in the attached diagram) via its planar sidewall (not shown in the attached diagram). The symmetrical mid-section of the clean water tank 1 presents an L-shape. The bottom of the clean water tank body 10 is sealed by the bottom cover assembly 42. Slide grooves or ribs (not shown in the attached diagram) are provided on the two vertical edges of the planar sidewall. Correspondingly, ribs or slide grooves (not shown in the attached diagram) are also provided on the two vertical edges of the planar sidewall of the wastewater tank 2, facilitating the sliding of the wastewater tank 2 and the clean water tank 1. 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 provided with a water pump connector 15. One end of the water pump connector 15 has an opening facing the bottom of the clean water tank 1 (not shown in the attached diagram), 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 31 of the water tank cover 3. A filter device (not shown in the attached diagram) is also provided around the water pump connector 15.

[0075] See Figures 3-10 In some embodiments, the sewage tank 2 includes a sewage tank body 20 and a bottom wall (not shown in the figure). The sewage tank 2 abuts against the flat side wall of the clean water tank 1 through the flat side wall. The symmetrical mid-section of the sewage tank 2 presents an inverted "L" shape. The peripheral wall (not shown in the figure) and bottom wall of the sewage tank 2 are closed, and only the top of the sewage tank 2 is open (not shown in the figure). The bottom wall is also provided with a guide block (not shown in the figure) for cooperating with the clean water tank 1. Slide grooves or ribs (not shown in the figure) are also provided on the two vertical edges of the flat side wall. Correspondingly, ribs or slide grooves (not shown in the figure) are also provided on the two vertical edges of the flat side wall 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 (not shown in the attached diagram) extends horizontally outward from the open planar sidewall. The eave includes the eave body (not shown in the attached diagram), which completely covers the entire top wall of the clean water tank. The first stepped surface of the tank cover 3 (not shown in the attached diagram) covers the entire eave. An upper interface (not shown in the attached diagram) and a lower interface (not shown in the attached diagram) extend from the upper and lower sides of the middle of the eave body. The lower interface abuts against the clean water tank outlet (not shown in the attached diagram), and the upper interface extends into the tank cover 3 and communicates with the clean water outlet 31. The lower surface of the eave and the top wall are sealed by a pressing annular weir.

[0076] In some further improved embodiments, such as Figure 3 , Figure 4 , Figure 7, Figure 8 As shown, a vertical plate (not shown in the attached figure) extends vertically upward on the side where the top wall intersects with the planar side wall. This plate, facing the front of the sewage tank 2 (not shown in the attached figure), can slide up and down to abut against the front end of a vertical side wall (not shown in the attached figure) and the eaves of the tank cover 3.

[0077] In some further improved embodiments, such as Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 8 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. 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.

[0078] In some further improved embodiments, such as Figure 1 , Figures 3 to 6 , Figure 8 , Figure 10 , Figure 11 , Figure 13 As shown, the clean water tank 1 is also provided with an L-shaped support surface (not shown in the attached figure) that abuts against the wastewater tank 2 from the top and bottom. The L-shaped support surface is provided with a guide opening (not shown in the attached figure) that cooperates with the guide block, so as to increase the volume of the clean water tank and appropriately reduce the volume of the wastewater tank within a limited space.

[0079] In some further improved embodiments, such as Figures 3 to 11 As 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 chamber 1 without being diluted by the whole tank of clean water, thereby 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.

A portion of the upper surface of the bottom cover middle frame 420 closes the clean water tank body 10. An annular groove 420a is provided at the edge of the area on the upper surface of the bottom cover middle frame 420 used to close the clean water tank body 10. The annular protrusion 10a of the clean water tank body 10 fits perfectly into the annular groove 120a of the bottom cover middle frame 12, and the two form a sealed connection.

[0083] In some further improved embodiments, the annular protrusion 10a and the annular groove 420a are sealed together by a sealant filled in the annular groove 420a.

[0084] In some further improved embodiments, the annular protrusion 10a and the annular groove 420a are fused together and filled into the annular groove 420a by a heat-induced ultrasonic welding process, while the clean water tank body 10 and the bottom cover frame 420 are pre-pressed by external force, thereby achieving a sealed weld between the two.

[0085] In some further improved embodiments, the annular protrusion 10a and the annular groove 420a are sealed by the O-ring filled in the annular groove 420a under the action of other external fastening structures, and the O-ring's deformation under pressure fills the gap between them.

[0089] In some further improved embodiments, such as Figure 14 , Figure 16 As shown, the two elastic electrodes 413 of the power access device 41 pass through the wire connection wire 4131 through the wire outlet hole 4111 and then through the wire through hole 4201 and are detachably electrically connected to the electrode connection seat mounting base 4205.

[0090] In one embodiment, the bottom of the sewage tank 1 is closed, the top wall of the adapter box 41 abuts against part of the bottom wall of the sewage tank, and the clean water tank 1, sewage tank 2, adapter box 41 and bottom cover assembly 42 together fill a complete, gapless column.

[0091] In one embodiment, a gap is provided between the adapter box 41 and the sewage tank 2 and / or between the sewage tank 2 and the clean water tank 1.

[0092] In some further improved embodiments, such as Figure 7 , Figure 9 As shown, the bottom cover 4 seals the clean water tank 1 and the wastewater tank 2 from the bottom. The power access device 41 is part of the bottom cover assembly 42. The power access device 41 uses the end face of the bottom cover frame 420 near the power access interface of the cleaning tool as the face shell. One end of the elastic electrode 413 protrudes from the outer wall of the bottom cover frame 420, and the other end is abutted against the wiring cavity by the spring 415. The lead wire 4131 of the elastic electrode 413 is detachably electrically connected to the water electrolysis module 13. The upper surface of the bottom cover frame 420 is provided with an annular groove 420a (there are two annular grooves 420a corresponding to the bottom of the clean water tank and the wastewater tank respectively). The bottom of the clean water tank body 10 extends downward with an annular protrusion 10a, and the bottom of the wastewater tank body 20 extends downward with an annular protrusion 20a. The two annular grooves 420a on the upper surface of the bottom cover frame 420 are sealed and connected to the annular protrusions 10a and 10a respectively.

[0093] In one embodiment, after the bottom cover frame 420 encloses the clean water tank 1 and the sewage tank 2, a portion of the upper surface of the bottom cover frame 420 also encloses the clean water tank 1 and the sewage tank 2. The upper surface of the bottom cover frame 420 also has an unenclosed area (not shown in the attached figure). The power supply access device 41 is installed in this unenclosed area. The unenclosed area is provided with a support platform H for installing the power supply access device 41.

[0094] In one embodiment, the bottom of the sewage tank 1 is closed, the top wall of the adapter box 41 abuts against part of the bottom wall of the sewage tank, and the clean water tank 1, sewage tank 2, adapter box 41 and bottom cover assembly 42 together fill a complete, gapless column.

[0095] In one embodiment, a gap is provided between the adapter box 41 and the sewage tank 2 and / or between the sewage tank 2 and the clean water tank 1.

[0096] In some further improved embodiments, such as Figure 8 , Figure 10As shown, the bottom cover 4 seals the sewage tank 2 from the bottom. The power access device 41 is part of the bottom cover assembly 42. The power access device 41 uses the end face of the bottom cover frame 420 near the power interface of the cleaning tool as the face shell. One end of the elastic electrode 413 protrudes from the outer wall of the bottom cover frame 420, and the other end is abutted against the wiring cavity by the spring 415. The lead wire 4131 of the elastic electrode 413 is detachably electrically connected to the water electrolysis module 13. The upper surface of the bottom cover frame 420 is provided with an annular groove 420a, and the bottom of the sewage tank body 20 extends downward with an annular protrusion 20a. The annular groove 420a and the annular protrusion 20a on the upper surface of the bottom cover frame 420 achieve a sealed connection. A section of the lead wire 4131 extends out of the bottom cover frame 420 and is held between the small protective wall (not shown in the attached diagram) extending downward from the clean water tank body to the bottom cover frame 420 and the outer wall of the sewage tank body 20. Since the clean water tank 1 and the sewage tank 2 have already achieved bottom sealing, there is no risk of the lead wire 4131 breaking after being submerged in water.

[0097] In some further improved embodiments, such as Figures 3 to 12 As shown, the bottom cover assembly 42 also includes a removable cover 421 for sealing the wiring cavity, which can be sealed onto the wiring cavity by means of a stud 1208.

[0098] In some further improved embodiments, all the internal structures of the power access device 41 are further compressed into the wiring cavity of the bottom cover assembly 42. The power access device 41 has now become part of the bottom cover assembly 42, which can further increase the volume of the clean water tank or the sewage tank without increasing the overall volume of the water tank.

[0099] It should be noted that the shape of adapter box 4 does not have to be... Figures 1-14 The hexahedral shape shown, as well as other regular shapes such as cylindrical, spherical, tubular, conical, and tetrahedral shapes, can all achieve the main design concept of this application as long as the two elastic electrodes can be stably connected to the power input interface of the cleaner body. They will not be described in detail here.

[0100] It should also be noted that the fit between the clean water tank 1, the wastewater tank 2, the water tank cover 3, and the bottom cover 4 is not entirely limited to... Figures 1-17 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.
