Description

[0001] This application is a divisional application of Chinese Patent Application No. 202310448906.9, entitled "A water tank with integrated cleaning and separation functions", the contents of which are hereby incorporated by reference. TECHNICAL FIELD

[0002] The present application relates to the technical field of cleaning, in particular to a water tank with integrated cleaning and separation functions. BACKGROUND

[0003] Current floor cleaning tools are generally classified into two branches: the air-dust circulation technology represented by vacuum cleaners and the water-dust circulation technology represented by drum-type scrubbers. However, due to the limitations of its working principle, the vacuum cleaner cannot clean some garbage and stains firmly attached to the ground. The "water-dust circulation" scrubber drives the cleaning cylinder to wipe the ground through the operation of the motor. The cleaning cylinder usually adopts a sponge cylinder structure, and the floor cleaner is also equipped with a water supply system and a water tank to clean the cleaning cylinder, thereby perfectly achieving the cleaning of the floor. In order to clean the cleaning cylinder, a closed cleaning space is usually provided in communication with the water supply system to clean the local drum, and clean water is provided to clean the cleaning cylinder, and then the sewage after cleaning the cleaning cylinder is pumped away.

[0004] The existing "air-dust circulation" scrubber can only adopt a water tank system with completely independent separation of the clean water tank and the sewage tank due to the limitations of the underlying technical principle. The water tank of the existing "water-dust circulation" scrubber mostly adopts a traditional split design scheme of the clean water tank and the sewage tank. There are also schemes of integrated design of the clean water tank and the sewage tank, which can allow the user to pour sewage while conveniently adding clean water, making the use more convenient.

[0005] Chinese Patents CN215937253U and CN218128365U disclose a water tank and a cleaning tool. The water tank is internally provided with a partition, which divides the water tank into a clean water area and a sewage area, and the clean water area and the sewage area are respectively provided with water level detection devices. The water tank combines the clean water area and the sewage area together, greatly saving the volume of the water tank, so that the cleaning tool can be designed to be small and light. Moreover, the clean water area and the sewage area are both provided with water level detection devices, which can allow the user to know in time that the clean water is used up or the sewage is full, thereby improving the cleaning effect.

[0006] Chinese patent CN215016831U discloses a water tank of a cleaning device and a cleaning device. The cleaning device comprises a machine body, and the water tank comprises a clean water tank, a sewage tank, a locking sleeve and a guide cover. The machine body is provided with a water tank mounting groove, and the top end of the water tank mounting groove is provided with a water outlet nozzle. The water tank comprises a clean water tank and a sewage tank. The clean water tank is provided with a first water inlet, and the sewage tank is provided with a second water inlet. The clean water tank and the sewage tank are connected through the locking sleeve and are installed in the water tank mounting groove. The guide cover comprises a first cover, a second cover and a sliding groove. One end of the sliding groove is connected with the first cover, and the other end is connected with the second cover. The first cover covers the first water inlet, and the second cover covers the second water inlet. The second cover is provided with a water filling port corresponding to the water outlet nozzle. When the water tank is installed, the water outlet nozzle is pressed upward by the sliding groove until the water outlet nozzle corresponds to the water filling port. The water outlet nozzle is embedded in the water filling port, which solves the technical problem that the repeated installation process of the water tank causes the installation part of the machine and the water tank to be worn and the use experience to be poor. The description of the 18th paragraph Figure 1 、 Figure 2 、 Figure 3 It can be seen that the guide cover comprises a relatively complex structure to cover the first water inlet and the second water inlet.

[0007] Chinese patents CN307180807S and CN307349603S each disclose an integrated clean water tank and sewage tank for a mop-sweeping integrated cleaning device.

[0008] Chinese patent CN114468899A discloses a clean water and sewage integrated water tank, which comprises a water tank body provided with a closed cavity. The water tank body is provided with a clean water cavity and a sewage cavity with variable storage space. The clean water cavity is provided with a water outlet connected with a first water pump, and the sewage cavity is provided with a water inlet connected with a second water pump. Since the water tank body is provided with a flexible partition, the clean water cavity and the sewage cavity for storing clean water and sewage can store more clean water or sewage with smaller volume, thereby prolonging the use time after adding water once. Meanwhile, each independent cavity can be provided with a partition plate for dividing the cavity into multiple interconnected partition plates, which can avoid liquid shaking during use and improve the use experience.

[0009] The existing technology has a split water tank system or an integrated water tank system, and the cooperation of the clean water tank and the sewage tank needs to be additionally configured with complex pipelines inside or outside the clean water tank and the sewage tank. In some schemes, the water tank cover can simultaneously cover the clean water tank and the sewage tank, but the clean water outlet of the water tank is arranged at a low position and is separated from the sewage backflow port by a long distance, and the manufacturing process and the maintenance process are relatively troublesome. The clean water outlet arranged at a low position is prone to cause water dripping at the clean water outlet, especially the schemes additionally provided with an extra power connection interface are prone to cause water dripping and short circuit. On the other hand, the cooperation mode of the clean water tank and the sewage tank is relatively complex, and some complex pipelines are additionally arranged inside or outside the clean water tank and the sewage tank, so that the space utilization rate of the whole water tank system is not high, and it is difficult to maintain the clean water tank or the sewage tank alone. Although the integrated water tank system has a clean water chamber and a sewage chamber separated in the water tank, the water tank itself is still an integrated structure, and the clean water tank and the sewage tank cannot be separately removed for maintenance or replacement. SUMMARY

The convex eave body 210 is extended with an upper interface part 211 and a lower interface part 212 on the upper and lower surfaces of the middle part, respectively. The lower interface part 212 abuts against the water outlet 1014 of the clean water tank, and the upper interface part 211 extends into the water tank cover 3 and is in communication with the clean water outlet 32. The lower surface of the convex eave 21 and the top wall 101 form a seal therebetween through the compression of the annular weir 1011. The water tank cover 3 indirectly connects the water suction pipe 14 in the clean water tank through the upper interface part 211 and the lower interface part 212 of the convex eave 21. The water suction pipe 14 is in communication with the clean water outlet 31 and the water suction joint 15.

[0088] Referring to Figure 6 , Figure 7 In some embodiments, the middle part of the convex eave body 210 is directly provided with a through hole for the water suction pipe 14 to directly pass through. In this way, the water suction pipe can directly pass through the water outlet 1014 and the through hole in the middle part of the convex eave body 210, extend into the water tank cover 3, and be in communication with the clean water outlet 32. The water tank cover 3 directly connects the water suction pipe 14 in the clean water tank through the middle part through hole of the convex eave 21. The water suction pipe 14 is in communication with the clean water outlet 31 and the water suction joint 15. When the clean water tank 1 needs to be maintained, the water tank cover 3 can be directly opened, the water suction pipe 14 can be straightened, and then the end of the water suction pipe extending into the water tank cover can be pulled out, thereby realizing the complete separation of the clean water tank 1 and the water tank cover 3.

[0089] Referring to Figure 9 , Figure 10 , Figure 12 , Figure 13In some embodiments, the chute or rib 200a1 of the sewage tank 2 is first aligned with the rib or chute 100a1 of the clean water tank 1, the planar side wall 200a of the sewage tank 2 is slid down on the planar side wall 100a of the clean water tank 1, the guide block 2021 of the sewage tank bottom wall 202 extends into the guide port 1021 on the clean water tank 1, then the lower surface of the eave 21 abuts the annular weir 1011 of the top wall 101, and the fixing hole 214 of the eave body 210 is screwed into the blind hole connecting stud 1012 of the top wall 101. After tightening, the lower surface of the eave 21 and the top wall 101 form a seal between them through the compression of the annular weir 1011, and at the same time, the atmospheric communication butt joint hole 1013 of the top wall 101 and the atmospheric communication port 213 of the eave 21 are also perfectly connected and conducted. When the water tank cover 3 is closed, the air in the clean water tank 1 can still be communicated with the outside atmosphere through the gap between the atmospheric communication butt joint hole 1013, the atmospheric communication port 213, the first step surface of the water tank cover (not labeled in the figure), and the eave 21, so that the water level in the clean water tank can decrease with the loss of clean water during use, and the clean water tank will not be unable to discharge clean water due to the pressure difference between the inside and outside of the tank.

[0090] In some further improved embodiments, as shown in Figure 10 、 Figure 12 、 Figure 14 , a vertical plate (not labeled in the figure) is vertically extended upward on the side where the top wall 101 intersects with the planar side wall 100a, and the vertical plate can slide up and down against the front face 100b of the sewage tank 1, the vertical side wall (not labeled in the figure) of the water tank cover 3, and the frontmost end of the eave 21.

The top end of the fastening member 111 is provided with a lock tongue 1111 which can elastically extend above the top of the panel 110. The lock tongue 1111 can be retracted below the top of the panel 110 by pressing the fastening member 111 to compress the spring 112. When the water tank is installed in place, the force pressing the fastening member 111 is released, and the lock tongue 1111 extends to complete the engagement and fixation of the water tank on the cleaner body.

[0094] In some further improved embodiments, as shown in Figure 16 As shown, the upper part of the clean water tank is slightly lower than the position of the holding mechanism 11, which can be set as a recess to form a recess 1001. The recess 1001 cooperates with the holding mechanism 11 to provide the user with a better holding feeling when holding the water tank.

[0095] In some further improved embodiments, as shown in Figure 3 、 Figure 5 、 Figure 8 、 Figure 10 、 Figure 13 As shown, the bottom of the clean water tank 1 is provided with a water electrolysis module 13, and a directional channel (not labeled in the figure) is arranged between the water electrolysis module 13 and the water suction connector 15, which ensures that the water just after electrolytic disinfection is directly sucked out of the clean water tank 1 without being diluted by the whole tank of clean water, thereby improving the efficiency of electrolytic disinfection and sterilization. The water electrolysis module 13 includes an electrolysis module shell 131, an electrolysis sheet 132, an indicator LED lamp 133 and an electrode connecting seat 134. The electrolysis sheet 132 and the indicator LED lamp 133 are installed in the electrolysis module shell 131 through the internal structure of the electrolysis module shell 131, and the electrode connecting seat 134 can realize waterproof connection of the water electrolysis module 13 to external power supply. When water flows through the electrolysis sheet 132, the electrolysis sheet 132 can electrolyze the water to generate effective disinfectant under the action of an electric field, and the indicator LED lamp 133 is used to indicate the working state of the water electrolysis module 13.

[0096] In some further improved embodiments, as shown in Figures 2-15 As shown, the integrated water tank capable of separating clean water and sewage further includes an electric connection member capable of taking power from outside the water tank and communicating with the access end of the water electrolysis module.

[0097] In some further improved embodiments, as shown in Figure 3 、 Figure 5 、 Figure 13 As shown, the electric connection member is a conversion box 4 with two elastic electrodes (not shown in the figure) and a wire outlet (not shown in the figure), and the water electrolysis module 13 is electrically connected to the elastic electrodes by a wire harness (not shown in the figure).

[0098] In some further improved embodiments, as shown in Figure 3 、 Figure 5 、 Figure 13 The adapter box 4 comprises a face shell 41 and a bottom shell 42 which are buckled to each other, and an electrode cap 43 which is elastically clamped between the face shell 41 and the bottom shell 42 and is abutted by a spring 45. After the water tank is installed into the cleaner, the electrode cap 43 can be stably electrically connected with a power supply interface (not shown in the figure) of the cleaner body under the elastic support of the spring 45.

[0099] In some further improved embodiments, the integrated water tank with clean and dirty water separation further comprises a water tank bottom cover assembly 12 which closes the clean water tank 1 and the dirty water tank 2 from the bottom.

[0100] In some further improved embodiments, the water tank bottom cover assembly 12 closes the dirty water tank 2 from the bottom.

[0101] In some further improved embodiments, as shown in Figure 1 、 Figure 3 、 Figures 5-13 The integrated water tank with clean and dirty water separation further comprises a water tank bottom cover assembly 12 which closes the clean water tank 1 from the bottom. The water tank bottom cover assembly 12 comprises 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 surrounds a wiring cavity (not shown in the figure) for the connection of the access end of the water electrolysis module 13.

[0102] In some further improved embodiments, as shown in Figure 13 、 Figure 15 The upper surface of the water tank bottom cover middle frame 12 closes the clean water tank 1 in part, and the upper surface area which is not used to close the clean water tank 1 is provided with a bearing table (not shown in the figure) for installing the adapter box 4, and the bearing table is provided with a wire passing port (not shown in the figure) which is opposite to the wire outlet port (not shown in the figure).

[0105] In some further improved embodiments, all the structures inside the adapter box 4 are further compressed into the wiring cavity of the bottom cover assembly 12 of the water tank to achieve that the volume of the sewage tank can be further increased without increasing the overall volume of the water tank.

[0106] It should be noted that the shape of the adapter box 4 can not be a hexahedron as shown in Figures 1-15 the figure, but other regular shapes such as cylinder, sphere, cylinder, cone, tetrahedron, etc. as long as the two elastic electrodes can be stably connected with the corresponding power supply interface of the cleaner body. Therefore, the main design idea of the present application is not repeated here.

[0107] It should also be noted that the cooperation between the clean water tank 1, the sewage tank 2, the water tank cover 3 and the adapter box 4 is not completely limited to Figures 1-14 the form that the four cooperating surfaces are completely filled. Of course, we can also make compromises on the corresponding position space by using other cooperation schemes between the entire water tank and the cleaner body, that is, intentionally hollowing out some space to adapt to the cooperation of other parts of the cleaner body. These schemes also embody the main design idea of the present application, which will not be repeated here.
