A sealing structure for the inner liner and the top cover, and a baby bottle washing machine.

Abstract

A sealing structure for an inner liner and a top cover, and a baby bottle washing machine, are disclosed. The sealing structure includes an inner liner and a top cover that fits over the top of the inner liner. A sealing strip is provided at the bottom of the top cover, and a support portion for supporting the top cover is provided at the top of the inner liner. The sealing strip rests downward or laterally against the support portion. A water-blocking rib extending downward is provided at the bottom of the top cover, extending into the interior of the inner liner. A support rib extending downward is also provided at the bottom of the top cover, with its bottom supported on the support portion. This sealing structure, by providing a sealing strip at the bottom of the top cover and a support portion at the top of the inner liner, seals the gap between the inner liner and the top cover. This prevents water from splashing onto the top cover during bottle washing and instead allows it to flow back into the inner liner, thus improving the user experience.

Description

Technical Field

[0001] This utility model relates to the technical field of baby bottle cleaning machines, and in particular to a sealing structure between the inner liner and the top cover, and a baby bottle cleaning machine. Background Technology

[0002] Chinese Patent Document No. CN221577482U, published on August 23, 2024, discloses a water supply structure for a multifunctional baby bottle cleaning device. The device includes a base, a baby bottle cleaning unit, and a formula maker. A water tank is mounted on the base, supplying water to either the baby bottle cleaning unit or the formula maker. However, a gap exists between the inner liner and the top cover of this baby bottle cleaning device. When the baby bottle is cleaned inside the inner liner, water can easily splash onto the top cover, and water may also leak out of the machine through the gap, affecting the user experience.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this utility model is to provide a sealing structure for the inner liner and the top cover that is simple in structure, has good sealing performance, is easy to use, provides a good user experience, and is highly practical, in order to overcome the shortcomings of the prior art.

[0005] A sealing structure for an inner liner and a top cover designed for this purpose includes an inner liner and a top cover that fits over the top of the inner liner. The structure is characterized in that: a sealing strip is provided at the bottom of the top cover, and a support portion for supporting the top cover is provided at the top of the inner liner, with the sealing strip pressing downward or laterally against the support portion.

[0006] The bottom of the top cover is equipped with a downward-extending water-blocking rib that extends into the inner liner.

[0007] The bottom of the top cover is provided with a downward-extending support rib, the bottom of which is supported on the support part.

[0008] The support rib is located outside the water-blocking rib, and the lower end of the water-blocking rib extends downward beyond the lower end of the support rib and the sealing strip.

[0009] The bottom of the top cover is provided with a sealing groove, and the sealing strip is installed in the sealing groove.

[0010] The bottom edge of the top cover is provided with an arc-shaped support rib, and the top edge of the inner liner is provided with a support edge, with the bottom of the support rib supported on the support edge.

[0011] The water-retaining bars, supporting bars, and bearing bars are distributed from the inside out in sequence, while the supporting parts and supporting edges are distributed from the inside out in sequence.

[0012] The sealing strip has a sealing part at the bottom and a sealing surface at the top of the support part. The sealing part abuts against the sealing surface downwards or laterally, and the sealing part and the sealing surface are in line contact or surface contact.

[0013] A sealing groove is formed between the water-blocking ribs, the supporting ribs, and the bearing ribs.

[0014] A baby bottle cleaning machine designed for this purpose is characterized by including the sealing structure of the inner liner and the top cover.

[0015] The sealing structure between the inner liner and the top cover of this utility model features a sealing strip at the bottom of the top cover and a support part at the top of the inner liner to support the top cover. The sealing strip presses downward or laterally against the support part, thereby sealing the gap between the inner liner and the top cover. This ensures that even if water splashes onto the top cover when the baby bottle is being washed inside the inner liner, it will not flow out of the bottle washing machine through the gap between the inner liner and the top cover, but will instead flow back into the inner liner, thus improving the user experience.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See Figures 1-5 The sealing structure of the inner liner and the top cover includes an inner liner 1 and a top cover 2 that covers the top of the inner liner 1. A sealing strip 3 is provided at the bottom of the top cover 2, and a support part 4 for supporting the top cover 2 is provided at the top of the inner liner 1. The sealing strip 3 presses down against the support part 4, thereby sealing the gap between the inner liner 1 and the top cover 2.

[0023] The bottom of the top cover 2 is provided with a downward-extending water-blocking rib 5. The water-blocking rib 5 extends downward into the inner liner 1. The water-blocking rib 5 can block most of the water splashed onto the top cover 2. This part of the water flows downward along the water-blocking rib 5 back into the inner liner 1.

[0024] The bottom of the upper cover 2 is provided with a downwardly extending support rib 6, the bottom of which is supported on the support part 4 so that the bottom of the upper cover 2 is supported on the top of the inner liner 1; the cooperation between the support rib 6 and the support part 4 also plays a sealing role, further improving the water-proof performance between the inner liner 1 and the upper cover 2.

[0025] The support rib 6 is located outside the water-blocking rib 5. The lower end of the water-blocking rib 5 extends downward beyond the support rib 6 and the lower end of the sealing strip 3, so that the water-blocking rib 5 can block most of the water splashed onto the upper cover 2. A small amount of water will enter the sealing groove 7 from the gap between the support part 4 and the water-blocking rib 5, but this part of the water will be blocked by the sealing strip 3, so it cannot pass through the sealing groove 7 and therefore cannot flow out of the bottle washing machine.

[0026] The bottom of the top cover 2 is provided with a sealing groove 7, and the sealing strip 3 is installed in the sealing groove 7.

[0027] The bottom edge of the top cover 2 is provided with an arc-shaped support rib 8, and the top edge of the inner liner 1 is provided with a support edge 9. The bottom of the support rib 8 is supported on the support edge 9, so that the bottom of the top cover 2 is supported on the top of the inner liner 1. The cooperation between the support rib 8 and the support edge 9 also plays a sealing role. Together with the sealing strip 3 and the support part 4, and the support rib 6 and the support part 4, a triple seal is formed, which greatly improves the water-proof performance between the inner liner 1 and the top cover 2.

[0028] Water-blocking ribs 5, supporting ribs 6 and supporting ribs 8 are distributed from the inside to the outside in sequence, and supporting parts 4 and supporting edges 9 are distributed from the inside to the outside in sequence; the lower end of supporting rib 6 extends downward beyond the lower end of supporting rib 8, and supporting parts 4 and supporting edges 9 are connected by vertical connecting parts 12 to form a step, and the height of supporting edges 9 is higher than the height of supporting parts 4.

[0029] The sealing strip 3 has a sealing part 10 at the bottom and a sealing surface 11 at the top of the support part 4. The sealing part 10 presses down against the sealing surface 11. The sealing part 10 and the sealing surface 11 are in line contact or surface contact to form a seal.

[0030] A sealing groove 7 is formed between the water-blocking rib 5, the supporting rib 6, and the supporting rib 8.

[0031] This baby bottle cleaner includes a sealed structure for the inner liner and the top cover.
