Description

Technical Field

[0001] This invention relates to the field of cleaning technology, and more particularly to an integrated water tank for cleaning tools. 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. 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.

[0005] 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.

[0006] 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

[0007] The main technical problem solved by this invention is to provide an integrated water tank for cleaning tools. This water tank is equipped with an adapter box for powering the water electrolysis module, located away from the clean water outlet, to avoid short circuits between the power-generating electrodes caused by water leakage. At the same time, the sealed bottom cover structure of the clean water tank, combined with the power-generating adapter box, ensures complete insulation and isolation between the water tank and the power-generating electrodes of the water electrolysis module, while also ensuring a certain degree of maintainability of the water electrolysis module. This facilitates production and allows consumers to replace the water electrolysis module themselves.

[0008] To solve the above-mentioned technical problems, the present invention provides an integrated water tank for cleaning tools, including a clean water chamber, a wastewater chamber and a water tank cover. The water tank cover can cover the clean water chamber and the wastewater chamber simultaneously from the top. The water tank cover is provided with a clean water outlet, and a water pumping pipe is directly or indirectly connected to the clean water chamber and connected to the clean water outlet. A water electrolysis module is provided at the bottom of the clean water chamber, and a water pumping connector connected to the water pumping pipe is provided at the same horizontal level to ensure that the water that has just been electrolyzed and disinfected is directly pumped out of the water tank.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] In one embodiment, the integrated water tank further includes an electrical connection component that is connected to the water electrolysis module and can draw power from outside the water tank.

[0011] In one embodiment, the integrated water tank further includes a water tank bottom cover assembly that encloses the clean water chamber and / or the sewage chamber.

[0012] In one embodiment, the water tank bottom cover assembly seals over the clear water chamber, and the water electrolysis module is mounted on the water tank bottom cover assembly with its access end passing through the closed interlayer of the water tank bottom cover assembly.

[0013] In one embodiment, the water pump is mounted on the bottom cover assembly of the water tank.

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

[0015] 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.

[0016] In one embodiment, the water tank bottom cover assembly includes a water tank bottom cover middle frame, the upper surface of which encloses a clear water cavity, and the lower surface of which surrounds a wiring cavity for the connection of the water electrolysis mold access terminal.

[0017] In one embodiment, one end of the elastic electrode is limited by the panel of the adapter box, and the other end is abutted by a spring inside the adapter box.

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

[0019] In one embodiment, a portion of the upper surface of the water tank bottom cover frame encloses the clear water chamber, while the upper surface area not used to enclose the clear water chamber is provided with a support platform for installing the adapter box. The support platform is provided with a cable passage port directly opposite the cable outlet.

[0020] 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 for detachable connection between the wiring cavity and the access end of the water electrolysis mold.

[0021] In one embodiment, both the sewage chamber and the adapter box are columnar with a single cross-section. The panel of the adapter box is located on the side wall of the adapter box, the outlet is located on the bottom wall of the adapter box, and the top wall of the adapter box is completely closed.

[0022] In one embodiment, the bottom wall of the adapter box and the bottom wall of the clear water chamber occupy the entire upper surface of the middle frame of the water tank bottom cover.

[0023] In one embodiment, the bottom of the sewage chamber is closed, the bottom wall of the sewage chamber abuts against the top wall of the adapter box, and the projection of the sewage chamber on its bottom wall completely covers the projection of the adapter box on its bottom wall. The clean water chamber, the sewage chamber, and the adapter box together fill a complete, gapless columnar body.

[0024] In one embodiment, the water tank bottom cover assembly further includes a removable cover for closing the wiring cavity.

[0025] Based on the above technical solution, the present invention can be further improved as follows.

[0026] In one embodiment, the elastic electrode comprises an electrode cap formed by stamping a sheet of metal.

[0027] This invention provides an integrated water tank for cleaning tools, comprising a clean water chamber, a wastewater chamber, and a tank lid. The tank lid can simultaneously cover both the clean water chamber and the wastewater chamber from the top. The tank lid has a clean water outlet and is also connected to a water suction pipe placed in the clean water chamber and communicating with the clean water outlet. A water electrolysis module is located at the bottom of the clean water chamber, and a water suction connector connected to the water suction pipe is also provided at the same horizontal level, ensuring that the water that has just been electrolyzed and disinfected is directly drawn away and sent out without being diluted by the water in the entire clean water chamber. Since the clean water outlet on the tank lid is far from the electrolysis module's electrode, and the clean water outlet is drawn by a negative pressure pump located outside the tank and placed on the cleaning tool body, the separation of the clean water outlet from the negative pressure pump's suction pipe when the tank is removed will only cause a small amount of water remaining at the clean water outlet on the tank lid to flow back into the clean water chamber. This minimizes the risk of short circuits between the electrolysis module's electrodes caused by water tank leakage. Meanwhile, the water tank bottom cover assembly, in conjunction with the power take-off adapter box, ensures complete insulation and isolation between the water tank and the power take-off electrodes of the water electrolysis module, while also ensuring a certain degree of maintainability of the water electrolysis module's connection. This facilitates production organization and allows consumers to replace the water electrolysis module themselves.

[0028] The beneficial effects of this invention are as follows: Firstly, a water electrolysis module is located at the bottom of the clear water chamber, and a water pump connector connected to the pumping pipe is also provided at the same horizontal level. This ensures that the water immediately after electrolysis and disinfection is directly pumped out without being diluted by the water in the entire clear water chamber, thus improving the efficiency of water electrolysis sterilization and disinfection. Secondly, the clear water outlet on the water tank cover is far from the power-taking electrodes of the water electrolysis module. When the water tank is removed, the separation of the clear water outlet from the negative pressure pump's pumping pipe will only cause a small amount of residual water at the clear water outlet on the water tank cover to flow back into the clear water chamber, minimizing the risk of short circuits between the power-taking electrodes of the water electrolysis module caused by water tank leakage. Furthermore, the use of a clear water tank bottom cover assembly in conjunction with a power-taking adapter box ensures complete insulation between the water tank and the power-taking electrodes of the water electrolysis module, while also ensuring a certain degree of maintainability for the water electrolysis module's connection. This facilitates production and allows consumers to easily replace the water electrolysis module themselves. Attached Figure Description

[0057] 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.

[0058] See Figures 1-3 , Figure 5 , Figure 7 This invention provides an integrated water tank for cleaning tools, comprising a clean water chamber 1, a wastewater chamber 2, and a tank lid 3. The tank lid 3 covers both the clean water chamber 1 and the wastewater chamber 2 from the top. The tank lid 3 has a clean water outlet 31 and is also connected to a water suction pipe 14 placed in the clean water chamber 1 and communicating with the clean water outlet 31. A water electrolysis module 13 is provided at the bottom of the clean water chamber 1, and a water suction connector 15 connected to the water suction pipe 14 is provided at the same horizontal level to ensure that the water that has just been electrolyzed and disinfected is directly drawn away and sent out of the tank.

[0059] In this embodiment, the water tank cover 3 can simultaneously cover the clear water chamber 1 and the wastewater chamber 2, which can improve the overall maintainability of the water tank. A water electrolysis module 13 is provided at the bottom of the clear water chamber 1, and a water pumping connector 15 connected to the water pumping pipe 14 is also provided at the same horizontal level. This can ensure that the water that has just been electrolyzed and disinfected is directly pumped out of the water tank, preventing the whole tank of clear water from diluting the electrolysis and disinfection capacity, and improving the disinfection and sterilization efficiency of the water electrolysis module. The clear water outlet 31 provided on the water tank cover 3 can reduce the number of pipes connected to the water tank and increase the space for pipe connections. It also increases the distance between the clear water outlet and the power supply interface, reducing the risk of short circuits in the power supply interface caused by water tank leakage. This facilitates the connection and maintenance of external pipes of the water tank, facilitates production organization, and also makes it easy for consumers to maintain the tank themselves.

[0060] Specifically, in the embodiments shown in the accompanying drawings, as Figures 1-7As shown, the integrated water tank for cleaning tools includes a clean water chamber 1, a wastewater chamber 2, and a tank lid 3. The clean water chamber 1 and the wastewater chamber 2 abut against each other through their respective flat side walls. The tank lid 3, with its stepped bottom surface, can simultaneously cover the clean water chamber 1 and the wastewater chamber 2 from the top. The clean water chamber 1 contains and outputs clean water to the cleaning tool. The top wall 101 of the clean water chamber has a water outlet 1014, and the bottom inner wall of the clean water chamber is connected to a water pump connector 15. The wastewater chamber 2 collects the wastewater output by the cleaning tool. The peripheral and bottom walls of the wastewater chamber are closed, with only the top of the wastewater chamber having an opening 201. The tank lid 3 can simultaneously cover the clean water chamber 1 and the wastewater chamber 2 from the top. The tank lid 3 has a clean water outlet 31 and a wastewater inlet 32, and the tank lid 3 is also directly or indirectly connected to a water pump pipe 14 placed in the clean water chamber. The water pump pipe 14 connects the clean water outlet 31 and the water pump connector 15.

[0061] See Figure 3 , Figure 5 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 close the top wall of the clear water chamber (not shown in the figure). The area around the long hook at the rear of the "η" shape, i.e., the second stepped surface (not shown in the figure), is used to close the opening of the sewage chamber (not shown in the figure). The long hook at the rear 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 chamber should be emptied in time.

[0062] See Figure 2 In some embodiments, the water tank cover 3 is provided with a sewage inlet 32 ​​at the same level and end face as the clean water outlet 31, so as to facilitate the sewage treated by the cleaner to be pumped back into the sewage chamber 2.

[0063] See Figure 1 , Figure 3 , Figure 5 , Figures 8-10In some embodiments, the clear water chamber 1 includes a clear water chamber body 10, a handle assembly 11, and a water tank bottom cover 12. The bottom of the clear water chamber body 10 is open, and the bottom of the peripheral wall of the clear water chamber body (not shown in the figure) has an annular protrusion 10a extending downward. The top of the clear water chamber body 10 is provided with a top wall 101, on which is provided a water outlet 1014 and an atmospheric communication docking hole (not shown in the figure). An annular weir (not shown in the figure) also extends upward on the top wall. The clear water chamber 1 abuts against the planar sidewall of the sewage chamber 2 (not shown in the attached diagram) via a planar sidewall. The symmetrical mid-section of the clear water chamber 1 presents an L-shape. The bottom of the clear water chamber 1 is sealed by the tank bottom cover 12. 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 sewage chamber 2, facilitating the sliding of the sewage chamber 2 and the clear water chamber 1. The upper part of the L-shape of the clear water chamber 1 is a column with a single cross-section. A water pump connector 15 is also provided at the bottom of the clear water chamber 1. One end of the water pump connector 15 has an opening facing the bottom of the clear water chamber 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 connects to the clear water outlet 32 ​​of the tank cover 3. A filter device (not shown in the attached diagram) is also provided around the water pump connector 15.

[0064] See Figures 1-3 , Figure 8 In some embodiments, the sewage chamber 2 includes a sewage chamber body 20 and a bottom wall (not shown in the figure). The sewage chamber 2 abuts against the planar side wall of the clean water chamber 1 through the planar side wall. The symmetrical mid-section of the sewage chamber 2 presents an inverted "L" shape. The peripheral wall (not shown in the figure) and bottom wall of the sewage chamber 2 are closed, and only the top of the sewage chamber 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 chamber 1. Slide grooves or ribs (not shown in the figure) are also provided on the two vertical edges of the planar side wall. Correspondingly, ribs or slide grooves (not shown in the figure) are also provided on the two vertical edges of the planar side wall of the clean water chamber 1 to facilitate the vertical sliding of the sewage chamber 2 and the clean water chamber 1. The lower part of the inverted "L"-shaped sewage chamber is a column with a single cross-section. A protruding eave 21 extends horizontally outward from the open planar sidewall. The protruding eave 21 includes the eave body (not shown in the attached drawing), which completely covers the top wall of the clear water chamber. The first stepped surface of the water tank cover 3 (not shown in the attached drawing) covers the entire protruding eave 21. The upper and lower interfaces 211 and 212 extend from the middle of the protruding eave body, respectively. The lower interface abuts against the outlet of the clear water chamber (not shown in the attached drawing), and the upper interface extends into the water tank cover 3 and communicates with the clear water outlet 31. The lower surface of the protruding eave 21 and the top wall are sealed by a pressing annular weir.

[0065] See Figure 8In some embodiments, the groove or rib of the sewage chamber 2 is first aligned with the rib or groove of the clear water chamber 1. The planar sidewall of the sewage chamber 2 is then slid downwards on the planar sidewall of the clear water chamber 1, allowing the guide block of the bottom wall of the sewage chamber to extend into the guide opening on the clear water chamber 1 (not shown in the attached figure). The downward sliding continues until the lower surface of the eaves 21 abuts against the annular weir of the top wall. A screw is driven into the blind hole connecting stud of the top wall (not shown in the attached figure) at the fixing hole of the eaves body (not shown in the attached figure). After tightening and compaction, the lower surface of the eaves 21 and the top wall are connected by... The compressed annular weir forms a seal between the two. At the same time, the atmospheric connection hole on the top wall and the atmospheric connection port of the eaves 21 (not shown in the attached diagram) are also connected and connected. After the water tank cover 3 is closed, the air in the clear water chamber 1 can still be connected to the outside atmosphere through the atmospheric connection hole, the atmospheric connection port, the gap between the first step surface of the water tank cover and the eaves 21. This allows the water level in the clear water tank to 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.

[0066] See Figure 6 , Figure 7 In some embodiments, the center of the eaves 21 is directly configured with a through hole through which the water pipe 14 can pass directly. This allows the water pipe to pass directly through the outlet 1014 and the through hole in the center of the eaves 21, extending into the water tank cover 3 and connecting to the clean water outlet 32. The water tank cover 3 connects directly to the water pipe 14 in the clean water chamber through the through hole in the center of the eaves 21. The water pipe 14 connects to the clean water outlet 31 and the water pump connector 15. When maintenance of the clean water chamber 1 is required, the water tank cover 3 can be opened directly, the water pipe 14 straightened, and then the end of the water pipe inserted into the water tank cover pulled out, thus achieving complete separation of the clean water chamber 1 from the water tank cover 3.

[0067] In some further improved embodiments, such as Figure 8 , Figure 9 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 faces the front of the sewage tank 1 (not shown in the attached figure) and 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 21 of the tank cover 3.

[0068] In some further improved embodiments, such as Figure 1 , Figure 3 As shown, after the water tank cover 3 covers the clean water chamber 1 and the sewage chamber 2, the side wall of the water tank cover is completely against 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.

[0069] In some further improved embodiments, such as Figures 1-10As shown, the clear water chamber 1 is also provided with an L-shaped support surface (not shown in the attached figure) that abuts against the sewage chamber 2. 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 clear water tank and appropriately reduce the volume of the sewage tank within a limited space.

[0070] In some further improved embodiments, such as Figure 1 , Figure 7 , Figure 9 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 is fixed to the upright plate by a fixing stud (not shown in the attached figure). The fastener is engaged between the panel 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. Pressing down on the fastener compresses the spring, which allows the locking tongue to retract below the top of the panel. After the water tank is installed in place, the force pressing on the fastener is released, and the locking tongue can extend to complete the engagement and fixation of the water tank on the cleaner body.

[0071] In some further improved embodiments, such as Figure 1 , Figure 3 , Figure 9 , Figure 10 As shown, the upper part of the water cavity, which is slightly lower than the gripping mechanism 11, can be set in a recessed shape to form a concave part (not shown in the attached figure). The concave part, together with the gripping mechanism 11, can give the user a better grip on the water tank.

[0072] In some further improved embodiments, such as Figure 3 , Figure 4 , Figure 6 As shown, a water electrolysis module 13 is located at the bottom of the clear water chamber 1. A directional channel (not shown in the attached diagram) surrounds the water electrolysis module 13 and the water pump connector 15, ensuring that the water immediately after electrolysis and disinfection is directly pumped out of the clear water chamber 1 without being diluted by the entire tank of clear 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 externally.
