[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] See Figures 1-10 The detachable spray arm mounting structure of this baby bottle cleaning machine includes an inner tank 1 and a spray arm assembly 2. A sealing element 3 is provided at the bottom of the inner tank 1, and a water column 4 is provided on the spray arm assembly 2. The water column 4 and the sealing element 3 are interlocked to allow the spray arm assembly 2 to be detachably fixed on the inner tank 1.

[0028] The upper end of the seal 3 is provided with a plug part 5, and the lower end of the water column 4 is provided with a plug hole 6. The plug part 5 and the plug hole 6 are plugged into each other to connect the spray arm assembly 2 and the seal 3. When installing the spray arm assembly 2, simply insert the spray arm assembly 2 downwards into the seal 3. When disassembling the spray arm assembly 2, simply pull the spray arm assembly 2 upwards from the seal 3.

[0029] The outer side of the insertion part 5 is provided with several rings of first protruding ribs 7. The first protruding ribs 7 are tightly fitted with the hole wall of the insertion hole 6, so that the insertion part 5 and the insertion hole 6 can be tightly inserted into each other, improving the connection strength between the spray arm assembly 2 and the seal 3, and at the same time achieving a good sealing effect, which can seal the gap between the inner tank 1 and the water column 4.

[0030] The water column 4 is made of plastic, and the sealing element 3 is made of flexible material, such as, but not limited to, silicone, rubber, EPDM, etc. Plastic has a lower cost, while flexible material provides a good connection and sealing effect.

[0031] The bottom of the inner liner 1 is provided with a mounting hole 8, and the sealing element 3 is provided with a mounting part 9, which is fixedly installed on the mounting hole 8.

[0032] The outer side of the mounting part 9 is provided with several rings of second ribs 10. The second ribs 10 are tightly fitted with the hole wall of the mounting hole 8, so that the sealing element 3 can be clamped on the mounting hole 8, and at the same time, it can achieve a good sealing effect.

[0033] The spray arm assembly 2 includes a water column 4 and a lower spray arm 11. The lower spray arm 11 is fitted at the bottom of the water column 4. A shelf 12 is suspended at the bottom of the inner tank 1. The lower spray arm 11 is located below the shelf 12. When the spray arm assembly 2 is installed, the water column 4 is inserted downward into the seal 3. When the spray arm assembly 2 is disassembled, the water column 4 is pulled upward from the seal 3 and drives the lower spray arm 11 to move upward. When the lower spray arm 11 moves upward to the corresponding position, it pushes the shelf 12 to move upward, thereby disassembling the shelf 12. Users do not need to reach to the bottom of the inner tank 1 to disassemble the shelf 12. They only need to pull the spray arm assembly 2 upward, which facilitates the disassembly of the shelf 12.

[0034] The bottom of the inner liner 1 is provided with several upward-extending support ribs 13, and the shelf 12 is provided with support edges 14 around its perimeter. The shelf 12 is supported on the support ribs 13 by the support edges 14, so that the shelf 12 is suspended in the inner liner 1.

[0035] The spray arm assembly 2 also includes a middle spray arm 19 and an upper nozzle 20. The middle spray arm 19 is fitted into the lower middle part of the water column 4, and the upper nozzle 20 is inserted into the top of the water column 4. The water column 4 is connected to the lower spray arm 11, the middle spray arm 19 and the upper nozzle 20 respectively.

[0036] The middle spray arm 19 is provided with several limiting blocks 21 around its periphery, and the shelf 12 is provided with a limiting ring 22 at its center. When the shelf 12 moves upward, it is limited by the limiting ring 22 to the limiting block 21. When the shelf 12 moves downward, it is limited by the lower spray arm 11, so that the shelf 12 will not detach from the spray arm assembly 2. The shelf 12 and the spray arm assembly 2 are used together.

[0037] A support part 23 is provided at the lower end of the water outlet column 4, and the water outlet column 4 is supported on the bottom wall of the inner tank 1 by the support part 23.

[0038] A washing pump 15 is installed below the inner tank 1. A water outlet connector 16 is installed on the washing pump 15. A plug groove 17 is installed at the lower end of the seal 3. The water outlet connector 16 and the plug groove 17 are plugged into each other. The water outlet connector 16 is connected to the water outlet column 4. The water outlet column 4 is provided with through holes 24 distributed vertically. The water outlet column 4 is connected to the lower spray arm 11, the middle spray arm 19 and the upper spray head 20 through the corresponding through holes 24.

[0039] The groove wall of the insertion slot 17 is provided with a third rib 18. The water outlet connector 16 is tightly fitted with the third rib 18, so that the water outlet connector 16 and the insertion slot 17 can be inserted tightly to each other, which improves the connection strength between the water outlet connector 16 and the sealing element 3, and at the same time achieves a good sealing effect, which can seal the gap between the inner tank 1 and the water outlet connector 16.

[0040] When the washing pump 15 is working, it draws water to the water outlet column 4, and then the water is sprayed into the inner tank 1 through the lower spray arm 11, the middle spray arm 19 and the upper spray head 20 respectively.
