[0030] Embodiment 1

[0031] This embodiment provides an internal water tank assembly 100. Refer to Figure 1 , the internal water tank assembly 100 includes: a clean water tank assembly and a waste water tank assembly; the clean water tank assembly includes a clean water tank 10 and a water outlet member. A water outlet 13 is provided at the bottom of the clean water tank 10. The water outlet member is installed on the clean water tank 10, and the water outlet 13 is conducted or cut off through the water outlet member; the waste water tank assembly includes a waste water tank 2 and a water inlet member. A water inlet 14 is provided at the bottom of the waste water tank 2. The water inlet member is installed on the waste water tank 2, and the water inlet 14 is conducted or cut off through the water inlet member.

[0032] Since the existing water tank structures generally adopt the method of opening holes above the rear side and connecting silicone rubber tubes to the bottom of the water tank for pumping water, this connection method often fails to make full use of the water in the water tank. Due to the gaps and the inclination of the mold, the water pump cannot completely extract the water at the bottom layer of the water tank. However, for the built-in water tank assembly 100 provided in this embodiment, the water inlet 14 and the water outlet 13 are respectively arranged at the bottoms of the clean water tank 10 and the waste water tank 2. The opening or closing of the water outlet 13 is realized through a water outlet component, and the opening or closing of the water inlet 14 is realized through a water inlet component. After the positions of the water inlet and outlet are moved from the original rear end to the bottom of the water tank, the water tank can be taken and placed up and down instead of being pushed and pulled back and forth as before. Moreover, the fact that the water inlet 14 and the water outlet 13 are placed at the bottom of the water tank enables the full utilization of the water in the water tank, and the phenomenon that the water at the original bottom layer cannot be pumped out no longer occurs.

[0033] Referring to Figure 1 , in this embodiment, preferably, a first inclined surface 1001 concave downward towards the water outlet 13 is provided at the bottom of the clean water tank 10. Specifically, the water outlet 13 is arranged at the central position of the bottom of the clean water tank 10, and the bottom surface of the clean water tank 10 is a first inclined surface 1001 inclined downward from the periphery towards the central position, so that the water in the clean water tank 10 flows towards the water outlet 13 through the first inclined surface 1001, ensuring that all the water in the clean water tank 10 can be fully utilized.

[0034] Continuing to refer to Figure 1 , in this embodiment, preferably, the above-mentioned water outlet component includes a first bead 8, an inclined track 7 and an electromagnetic coil 11; the inclined track 7 is arranged on the bottom wall inside the clean water tank 10, and the lower end of the inclined track 7 is connected to the water outlet 13. A boss 21 is provided at the end of the inclined track 7, and the electromagnetic coil 11 is arranged in the boss 21; in the natural state, the first bead 8 is located above the water outlet 13 and is used to block the water outlet 13. When the electromagnetic coil 11 acts on the first bead 8, the first bead 8 can roll upward along the inclined track 7 to conduct the water outlet 13.

[0035] Specifically, the inclined track 7 includes a horizontal section, a vertical section, and a circular groove section. The horizontal section intersects with the vertical section. The circular groove section is arranged on the upper surface of the inclined track 7. The horizontal section is fixedly installed on the bottom wall inside the water purification tank 10, and one end of the horizontal section is connected to the water outlet 13. The circular groove section can accommodate the first bead 8 to roll up and down relative to the inclined track 7. The vertical section is connected to the boss 21, and the boss 21 is a hollow structure. The electromagnetic coil 11 can extend into the boss 21. The first bead can be a steel bead. In the natural state, the first bead 8 is located above the water outlet 13, blocking the water outlet 13. When the electromagnetic coil 11 is energized, a magnetic field is generated, causing the first bead 8 to move along the circular groove section in the direction close to the electromagnetic coil 11, thereby conducting the water outlet 13. When the work is finished, the electromagnetic coil 11 is powered off, and the first bead 8 moves downward along the circular groove section under the action of its own gravity. The first bead 8 falls above the water outlet 13, thereby blocking the water outlet 13. Through the cooperative setting of the electromagnetic coil 11 and the first bead 8, the first bead 8 can quickly conduct or block the water outlet 13 at the bottom of the water purification tank 10, enabling the complete utilization of the water in the water purification tank 10 and ensuring the working reliability of the water purification tank assembly.

[0036] In this embodiment, preferably, a rubber sealing ring is provided at the water outlet 13. Specifically, the rubber sealing ring is arranged along the circumference of the water outlet 13. By providing the rubber sealing ring, the sealing effect can be improved. It is ensured that in the natural state, the first steel bead presses the rubber sealing ring at the water outlet 13 with its own gravity to achieve sealing, improving the sealing effect of the water outlet 13.

[0037] Continue to refer to Figure 1 In a further preferred embodiment of this embodiment, the water outlet member further includes a water purification tank filter screen 9, and the water purification filter screen cover is arranged outside the water outlet member.

[0038] Specifically, a groove is provided at the bottom of the water purification tank 10, and the water purification tank filter screen 9 can be inserted into the groove at the bottom of the water purification tank 10 for connection. The water purification tank filter screen 9 is integrally sleeved outside the first bead 8 and the inclined track 7, which can play a restraining role on both sides of the first bead 8. The water purification tank 10 filter screen is a cuboid structure with five sides meshed and one side open, and the width is slightly larger than that of the first bead 8, so that the first bead 8 can only slide up and down along the inclined track 7, avoiding the first bead 8 deviating from the trajectory of the circular groove section when moving relative to the inclined track 7. At the same time, the water purification tank filter screen 9 is detachably installed on the water purification tank 10, facilitating the replacement of the water purification tank filter screen 9, and thus facilitating the maintenance of the built-in water tank assembly 100.

[0039] Continue to refer to Figure 1 In a further preferred embodiment of this embodiment, the water purification tank assembly further includes a tank cover assembly. The tank cover assembly includes a water purification tank cover 6 and a tank handle 5. Clasps 12 are provided on both sides of the water purification tank 10, and the water purification tank cover 6 is detachably connected to the water purification tank 10 through the clasps 12. The tank handle 5 is hinged to the water purification tank cover 6.

[0040] Specifically, a groove is provided at the top of the clean water tank cover 6, and the water tank handle 5 is hinged in the groove. The water tank handle 5 can rotate unidirectionally around the clean water tank cover 6. When in use, the water tank handle 5 is rotated upward to the vertical state for lifting and placing. When not in use, the water tank handle 5 is placed down into the groove. When the water tank handle 5 is not in use, it is stored, which can save the overall space of the built-in water tank assembly 100, thereby relatively increasing the volume of the clean water tank 10. Snap fasteners 12 in the form of Lock&Lock are provided on both sides of the clean water tank 10 for the mating connection between the clean water tank cover 6 and the clean water tank 10 to ensure the stability of the connection between the clean water tank 10 and the clean water tank cover 6 when lifting water with the water tank handle 5.

[0041] Refer to Figure 1 , in this embodiment, preferably, the water inlet member includes a second bead 17 and a water pump. In the natural state, the second bead 17 is located above the water inlet 14 for blocking the water inlet 14. When the water pump works, the second bead 17 moves relative to the water inlet 14 for conducting the water inlet 14.

[0042] Specifically, in the natural state, the second bead 17 is located above the water inlet 14, and the water inlet 14 is blocked by the self-gravity of the second bead 17. When the water pump works and pumps water into the wastewater tank 2, the water pressure lifts the second bead 17, causing it to separate from the water inlet 14, thereby conducting the water outlet 13 and allowing water to enter the wastewater tank 2 through the water inlet 14; when the work is finished and the water pump stops working, the second bead 17 naturally falls above the water outlet 13, thereby blocking the water outlet 13. Through the cooperative setting of the water pump and the second bead 17, the second bead 17 can quickly conduct or block the water inlet 14 at the bottom of the wastewater tank 2, enabling the full utilization of the water in the wastewater tank 2 and ensuring the working reliability of the wastewater tank assembly.

[0043] Refer to Figure 1 , in this embodiment, preferably, a second inclined surface 1002 concave downward toward the water inlet 14 is provided at the bottom of the wastewater tank 2. Specifically, the water inlet 14 is provided at the central position of the bottom of the wastewater tank 2, and the bottom surface of the wastewater tank 2 is a second inclined surface 1002 that slopes downward from the periphery to the central position, causing the water in the wastewater tank 2 to flow toward the water inlet 14 along this second inclined surface 1002 to ensure the full utilization of all the water in the wastewater tank 2.

[0044] In this embodiment, preferably, a rubber sealing ring is provided at the water inlet 14. Specifically, the rubber sealing ring is arranged along the circumference of the water inlet 14. By providing the rubber sealing ring, the sealing effect can be improved. It is ensured that in the natural state, the second steel ball presses the rubber sealing ring at the water inlet 14 with its own gravity to achieve sealing and improve the sealing effect of the water inlet 14.

[0045] Continue to refer to Figure 1, in a further preferred embodiment of the present embodiment, the above water inlet member further includes a waste water tank filter screen 3. The waste water filter screen is cylindrical and covers the outside of the water inlet member.

[0046] Specifically, a groove is provided at the bottom of the waste water tank 2. The waste water tank filter screen 3 is inserted into the waste water tank 2 through the groove. The waste water tank filter screen 3 is integrally sleeved outside the second bead 17 and can restrict both sides of the second bead 17. The filter screen of the waste water tank 2 is a cylinder with an open bottom surface, and the diameter is slightly larger than the diameter of the second bead 17, allowing the second bead 17 to move up and down to a certain extent, avoiding the second bead 17 deviating from the vertical trajectory when moving relative to the water inlet 14. At the same time, the waste water tank filter screen 3 is detachably installed on the waste water tank 2, facilitating the replacement of the waste water tank filter screen 3, and thus facilitating the maintenance of the built-in water tank assembly 100.

[0047] Continue to refer to Figure 1 , in a further preferred embodiment of the present embodiment, the above waste water tank assembly further includes a tank cover assembly. The tank cover assembly includes a waste water tank cover 4 and a water tank handle 5. Clasps 12 are provided on both sides of the waste water tank 2. The waste water tank cover 4 is detachably connected to the waste water tank 2 through the clasps 12, and the water tank handle 5 is hinged to the waste water tank cover 4.

[0048] Specifically, a groove is provided at the top of the waste water tank cover 4. Mounting holes 4001 are provided on both sides of the groove respectively. Mounting parts 5001 are provided on both sides of the water tank handle 5 respectively. The water tank handle 5 is hinged and fixed in the groove. The water tank handle 5 is connected through the cooperation of the mounting part 5001 and the mounting hole 4001. The water tank handle 5 can rotate unidirectionally around the waste water tank cover 4. When in use, the water tank handle 5 is rotated upward to the vertical state for lifting and placing. When not in use, the water tank handle 5 is put down and placed in the groove. The water tank handle 5 is stored when not in use, which can save the overall space of the built-in water tank assembly 100, thereby relatively increasing the volume of the waste water tank 2. Clasps 12 in the form of Lock&Lock are provided on both sides of the waste water tank 2 for the mating connection between the waste water tank cover 4 and the waste water tank 2, ensuring the stability of the connection between the waste water tank 2 and the waste water tank cover 4 when lifting water with the water tank handle 5.

An inlet hole 16 is provided at the bottom of the waste water tank cavity 20. The water inlet 14 is communicated with the inlet hole 16.

[0050] Specifically, when the clean water tank 10 is matched with the water tank bracket 1, the clean water tank 10 is placed in the clean water tank cavity 19, and the electromagnetic coil 11 located in the clean water tank cavity 19 extends into the boss 21, and the axis of the water outlet 13 coincides with the axis of the water outlet hole 15, and the water outlet hole 15 is connected to a water outlet pipe, through which the water in the clean water tank 10 is discharged; when the waste water tank 2 is matched with the water tank bracket 1, the waste water tank 2 is placed in the clean water tank cavity 19, and the water inlet hole 16 is connected to a water inlet pipe, through which water is input into the waste water tank 2. The clean water tank 10 and the waste water tank 2 water tank bracket 1 are detachably connected, which is convenient for taking and placing the clean water tank 10 and the waste water tank 2.
