Detailed Implementation

[0014] To make this utility model clearer, the water supply and filtration structure of a baby bottle washing machine according to this utility model will be further described below with reference to the accompanying drawings. The specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0015] like Figure 1 , Figure 2 As shown, a water supply and filtration structure for a baby bottle cleaner is located in a water tank 100 outside the main body of the baby bottle cleaner. The water tank 100 serves as a water storage container to provide clean water for cleaning baby bottles.

[0016] The water supply filtration structure includes a water inlet 110 at the bottom of the water tank 100 and a filter assembly 200 that is rotatably detachable from the water inlet 110. The water inlet 110 is a stepped straight pipe structure that is larger at the top and smaller at the bottom. It is integrally formed with the water tank 100. The smaller end of the water inlet 110 extends out of the bottom wall of the water tank 100 and is connected to a power component such as a water pump via a flexible hose. The larger end is located inside the water tank 100 and can be detachably connected to the filter assembly 200 via a threaded structure or a screw-lock structure. This structure facilitates the replacement of the filter assembly 200. The threaded structure and the screw-lock structure are conventional detachable structures and will not be described in detail here. The figure shows the screw-lock structure.

[0017] The filter assembly 200 includes a base 210, which serves as a support connector, detachably connected at one end to the water inlet 110 and detachably connected at the other end to the filter sleeve 220. Figure 3As shown, the filter sleeve 220 is a sleeve structure with an open lower end and a limiting upper end. Its peripheral sidewalls are connected by ribs to form a hollow structure, which serves as a flow channel 221. The specific hollow shape can be rectangular, circular, or other shapes that facilitate liquid flow. The filter sleeve 220 contains a filter body 230, which has a water inlet 232 and a water outlet 233. In this embodiment, the filter body 230 is a scale filter element, which is a tubular filter element 231 with a porous filtration structure. The lower end of the central hole of the tubular filter element 231 is the water outlet 233. A sealing mounting sleeve 240 is fitted on this end, which is sealed and connected to the base 210 and sealed and connected to the water inlet 110. The other end of the tubular filter element 231 is fitted with a cap 250 that closes the central hole. The cap 250 is limited by the limiting stop at the upper end of the filter sleeve 220, so that the tubular filter element 231 has a single water outlet 233. The porous structure on the periphery of the tubular filter element 231 serves as the water inlet 232. The water inlet 232 is connected to the flow channel 221 formed by the hollow structure on the periphery of the filter sleeve 220. The water outlet 233 is sealed and connected to the water inlet 110. When the water in the water tank enters the filter body 230 through the flow channel 221 and the water filter inlet 232, it is filtered by the dense porous structure on the side wall of the filter body 230, and finally enters the water inlet 110 through the water filter outlet 233. The specific water flow path is shown by the arrow in the figure.

[0018] In some embodiments, the base 210 and the sealing mounting sleeve 240 have the following specific structures: [Combined] Figure 4 As shown, the base 210 has a sleeve-like structure, including an inner sleeve 211 and an outer sleeve 212 arranged concentrically. The inner and outer sleeves are connected as one unit by an annular connecting plate 213. A limiting step 214 is provided at the bottom of the inner sleeve 211. The inner sleeve 211 is convex, and the lower ends of the inner and outer sleeves, along with the connecting plate 213, form a downward-opening annular mounting groove 215. A sealing gasket 216 is installed within the annular mounting groove 215. The outer sleeve 212 is provided with a detachable connection structure, such as threads and a screw thread structure, for fitting the water inlet 110. The figure shows a screw thread groove, and the corresponding water inlet 110 is provided with a screw thread head. The upper part of the inner sleeve 211 is provided with a detachable structure, such as threads and a screw thread structure, for fitting the filter sleeve 220. The figure shows an external thread on the outer wall of the inner sleeve 211, and the corresponding filter sleeve 220 is provided with an internal thread. Figure 5As shown, one end of the sealing mounting sleeve 240 has an annular mounting groove 241 that matches the cross-sectional shape of the tubular filter element 231 and can be positioned therewith. An annular sealing groove 242 is located on the lower part of the outer peripheral side of the sealing mounting sleeve 240. A sealing ring 243, an O-ring, is installed inside the annular sealing groove 242, forming a compression seal with the inner wall of the water inlet 110. When the filter assembly 200 is assembled, the bottom end of the sealing mounting sleeve 240 is limited to the limiting step 214. The sealing ring 243 deforms under pressure, sealing the sealing mounting sleeve 240 and the base 210, preventing filtered water from entering the water tank 100. When the filter assembly 200 is connected to the water inlet 110, the sealing gasket 216 is pressed against the end face of the water inlet 110 to form a sealed connection, preventing unfiltered water from entering the water inlet 110.

[0019] This device features a detachable filter assembly 200, facilitating its removal and installation. Furthermore, the detachable sealing structure formed by the base 210 and filter sleeve 220 facilitates the replacement of the filter element 230. Overall, this structure is compact, easy to assemble and disassemble, and convenient to use.
