[0039] The following is for reference. Figure 1 and Figure 2 Description of a cleaning water tank according to an embodiment of the present utility model.

[0040] like Figure 1 and Figure 2 As shown, the cleaning water tank according to an embodiment of the present invention includes an inner tank 100, an outer water tank 200, and an inner water tank 300.

[0041] The inner liner 100 has an inner liner cavity 110, which can hold water, and a washing device 120 is installed inside the inner liner cavity 110; see reference. Figure 3 The outer water tank 200 is used for water storage, and a water pump 130 is connected between the outer water tank 200 and the inner tank 100; see reference. Figure 4 , Figure 5 The inner water tank 300 is located inside the outer water tank 200. A filter port 310 is provided on the lower side of the inner wall of the inner water tank 300. A filter 600 is covered on the upper side of the filter port 310. A water storage space 220 is formed between the bottom wall 301 of the inner water tank and the bottom wall 201 of the outer water tank. Water from the inner water tank 300 can pass through the filter 600 and the filter port 310 in sequence to enter the water storage space 220. The water pump 130 can draw water from the water storage space 220 into the inner liner cavity 110.

[0042] For example, taking the cleaning of baby bottles as an example, such as Figure 1 and Figure 2 As shown, the inner liner 100 has an inner cavity 110, which can hold water, and the baby bottle is also placed inside the inner cavity 110. The inner liner 100 remains relatively stationary during operation. A washing device 120 is installed inside the inner cavity 110, which is responsible for washing. (Refer to...) Figure 3 The outer water tank 200 is used for water storage, and a water pump 130 is connected between the outer water tank 200 and the inner tank 100. The inner water tank 300 is located inside the outer water tank 200 and can also store water. (Refer to...) Figure 4 , Figure 5 A filter port 310 is provided on the lower side of the inner wall of the inner water tank 300, and a filter 600 is covered on the upper side of the filter port 310 to filter the water in the inner water tank 300. A water storage space 220 is formed between the bottom wall 301 of the inner water tank and the bottom wall 201 of the outer water tank. That is, after the inner water tank 300 is installed in the outer water tank 200, a cavity is formed between the bottom of the inner water tank 300 and the inner side of the outer water tank 200 as the water storage space 220. The water in the inner water tank 300 can pass through the filter 600 and the filter port 310 in sequence to enter the water storage space 220. The water pump 130 can draw the water in the water storage space 220 into the inner liner cavity 110, and the washing device 120 can use the water in the inner liner cavity 110 to wash the baby bottle.

[0043] The outer water tank 200 and the inner water tank 300 together form a water tank assembly, which can be used to collect water. In actual operation, refer to... Figure 1 First, place the baby bottle into the inner liner 100, and fill the inner water tank 300 of the water tank device with water. Then, the water in the inner water tank 300 is filtered by the filter 600 and flows into the lower water storage space 220 through the filter port 310 of the inner water tank 300. The water in the water storage space 220 can then be drawn into the inner liner cavity 110 by the water pump 130, and the washing device 120 can be started to work, using the water in the inner liner cavity 110 to wash the baby bottle.

[0044] Since the water filtration process of filter 600 is relatively time-consuming, water can be filled into the water tank and left for a period of time. Once there is enough filtered water in the water storage space 220, the water pump 130 can be started to pump water. This allows sufficient time for the filtration process to ensure the filtration effect.

[0045] In some embodiments of this utility model, reference is made to Figure 3 The outer water tank 200 and the inner water tank 300 are detachably connected, so the outer water tank 200 and the inner water tank 300 can be separated for cleaning.

[0046] In some embodiments of this utility model, a handle 400 is provided at the upper end of the inner water tank 300. The handle 400 includes a central grip portion 410 and connecting portions 420 on both sides. A connecting groove 421 is provided on the lower side of the connecting portion 420, and the connecting groove 421 is engaged with the upper opening of the inner water tank 300. The user can hold the handle 400 to lift the water tank device composed of the outer water tank 200 and the inner water tank 300, or hold the handle 400 to detach the inner water tank 300 from the outer water tank 200.

[0047] A user-friendly handle 400 is installed at the upper part of the inner water tank 300. This handle 400 consists of key parts such as a grip 410 and a connecting part 420. Each connecting part 420 has a connecting groove 421 on its lower side, which precisely engages with the opening at the upper end of the inner water tank 300, ensuring a secure connection between the handle 400 and the inner water tank 300. This design not only improves the portability of the water tank device but also ensures the safety and comfort of the user during operation.

[0051] In some embodiments of this utility model, the upper side or sidewall of the filter 600 serves as the input section, and the lower side of the filter 600 serves as the output section connected to the filter port 310. Water in the inner water tank 300 can pass through the input section of the filter 600 and enter the filter 600 for filtration and purification, and then be discharged from the output section of the filter 600 and flow into the water storage space 220 from the filter port 310.

[0052] In some embodiments of this utility model, the filter 600 and the inner water tank 300 are detachably connected, so that the filter 600 can be removed for cleaning or replacement.

[0053] In some embodiments of this utility model, the lower end and side wall of the inner water tank 300 are respectively provided with a first support groove 330 and a second support groove 340, which can respectively abut against the bottom wall 201 of the outer water tank and the side wall of the outer water tank 200. That is, after the inner water tank 300 is installed into the outer water tank 200, at least the first support groove 330 or the second support groove 340 of the inner water tank 300 can support the outer water tank 200, which not only ensures that the inner water tank 300 is sufficiently stable after being installed into the outer water tank 200, but also ensures that the water storage space 220 can leave enough space.

[0054] In some embodiments of this utility model, an inner wall support rib 250 is provided on the bottom wall 201 of the outer water tank. The inner wall support rib 250 can hold the second support groove 340 or the bottom wall 301 of the inner water tank, ensuring that the inner water tank 300 is sufficiently stable and reliable after being installed into the outer water tank 200.

[0055] In some embodiments of this utility model, an outer positioning groove 260 is provided on the outer water tank 200, and an outer positioning plate 423 is provided on the side wall of the handle 400. After the inner water tank 300 is installed into the outer water tank 200, the outer positioning plate 423 on the inner water tank 300 can hold against the outer positioning groove 260 on the outer water tank 200, further ensuring that the inner water tank 300 is sufficiently stable after being installed into the outer water tank 200.

[0056] In some embodiments of this utility model, the first support groove 330 has a filter receiving cavity 331, the filter port 310 is located on the bottom wall of the filter receiving cavity 331, the filter 600 is inserted into the filter receiving cavity 331, and the inner side wall of the filter receiving cavity 331 holds the outer side wall of the filter 600. This ensures that the filter 600 is securely installed in the inner water tank 300.

[0057] In some embodiments of this utility model, reference is made to Figure 3 The cleaning water tank of this utility model also includes a base frame 800, on which the outer water tank 200 can be placed. An outer water tank outlet 230 is opened on the bottom wall 201 of the outer water tank, and a water outlet switch 700 is provided on the outer water tank outlet 230. (Refer to...) Figure 8 , Figure 9 The water outlet switch 700 includes a switch linkage 710, a sealing plate 720, and a return spring 730. The switch linkage 710 passes through the outer water tank outlet 230 and can move up and down. The lower end of the switch linkage 710 has a linkage protrusion 711. The sealing plate 720 can cover the upper side of the outer water tank outlet 230. The return spring 730 is fitted onto the switch linkage 710.
