[0002] Current bottle washing machines consist of a main body, inner tank, top cover, water tank, and multiple water pumps. The inner tank contains a heating element and a rotating rinsing arm assembly. The top cover is located at the top opening of the inner tank. The rotating rinsing arm assembly sprays water onto the bottles inside the inner tank. This assembly includes a central spray column and a horizontally rotating spray arm. The central spray column is fixed inside the inner tank, and the rotating spray arm rotates horizontally around it. The rotating spray arm has multiple first-stage rinsing holes, and several smaller spray columns are connected around the central spray column, each with multiple second-stage rinsing holes. With the bottle opening facing down, the smaller spray columns extend into the bottle. Because the direction of the second-stage rinsing holes on the smaller spray columns is fixed and their number is limited, the inner walls of the bottles are not thoroughly cleaned. Utility Model Content

[0003] The purpose of this utility model is to provide a baby bottle spraying mechanism for a baby bottle washing machine that provides good and thorough cleaning of baby bottles.

[0004] The purpose of this utility model is achieved as follows: A bottle washing machine includes a bottle spraying mechanism comprising a main water channel and multiple branch water channels. The bottom surface of the main water channel has a water inlet, and the top surface of the main water channel has a central column. One end of each branch water channel is connected to the main water channel. A rotating spraying arm is horizontally rotatable on each branch water channel. A supporting protrusion is provided on each branch water channel, and the rotating spraying arm is horizontally rotatable on the supporting protrusion. The rotating spraying arm includes a rotating arm and a spraying column connected together. The spraying column is located on the top surface of the rotating arm. The rotating arm and the spraying column are respectively provided with a first spraying hole and a second spraying hole. The bottom surface of the rotating arm has a downwardly protruding connecting cylinder, which is inserted into the supporting protrusion. The connecting cylinder and the supporting protrusion are horizontally rotatable. The rotating arm is connected to the branch water channel through the supporting protrusion. After water enters the main water channel of this invention, the water then enters each branch water channel and is finally sprayed out from each rotating spray arm. Driven by the water flow, the rotating spray arm will automatically rotate and spray. Compared with the previous spray arm, the rotating spray arm of this invention has a larger spray range, a reasonable layout, and a better, more thorough, and dead-angle-free cleaning effect on baby bottles.

[0005] The present invention can be further improved in the following ways.

[0006] The outer wall of the connecting cylinder is provided with a rotating annular protrusion, and the inner wall of the supporting protrusion is provided with a rotating annular groove corresponding to the position of the rotating annular protrusion. The rotating annular protrusion and the rotating annular groove are in a concave-convex fit, which facilitates the disassembly and assembly of the rotating spray arm. The rotating spray arm can also rotate horizontally around the supporting protrusion.

[0007] The rotating arm is composed of an upper arm and a lower arm connected together. The shape and size of the upper arm and the lower arm are matched.

[0042] This is a more specific technical solution of the present invention.

[0043] The inner liner 6 has an inner waterproof annular groove 61 around its circumference at the opening. The lower edge of the cover 2 sits within the inner waterproof annular groove 61. Multiple drainage notches 62 are spaced apart on the side wall of the inner waterproof annular groove 61, connecting the inner waterproof annular groove 61 to the inner liner 6. This invention, by providing an inner waterproof annular groove and drainage notches at the opening of the inner liner, allows water flowing down the inner wall of the cover during operation to flow back into the inner liner, thus preventing water accumulation on the top of the casing and providing convenience for the user.

[0044] An outer waterproof annular groove 63 is provided around the perimeter of the opening, located outside the inner waterproof annular groove 61. This invention features a reasonable structural design, ensuring that even if the inner waterproof annular groove 61 is full, water will overflow into the outer waterproof annular groove 63, effectively preventing water from flowing onto the top surface of the casing 1.

[0045] The depth of the outer waterproof annular groove 63 is greater than the depth of the inner waterproof annular groove 61.

[0046] The thickness of the lower edge of the cover 2 is less than the width of the inner waterproof annular groove 61. Therefore, the lower edge of the cover 2 will not occupy too much volume of the inner waterproof annular groove 61, the inner waterproof annular groove 61 can hold more water, and the inner waterproof annular groove 61 is less likely to overflow into the outer waterproof annular groove 63.

[0047] The horizontal height of the drainage gap 62 is lower than the horizontal height of various locations in the inner waterproof annular groove 61, so that the water in the inner waterproof annular groove 61 flows to the drainage gap 62 and then flows out of the inner waterproof annular groove 61.

[0048] The opening is surrounded by a lower outward flange 65, and the outer waterproof annular groove 63 and the inner waterproof annular groove 61 are provided on the lower outward flange 65. The structural design of this utility model is reasonable and facilitates the design of the outer waterproof annular groove 63 and the inner waterproof annular groove 61.

[0049] The lower edge of the cover 2 is provided with an upper outward flange 64, which sits on the lower outward flange 65 to achieve positioning and support of the cover 2.

The rotating spraying arm 44 includes a rotating arm 47 and a spraying column 48. The spraying column is located on the top surface of the rotating arm. The rotating arm and the spraying column are respectively provided with a first spraying hole 49 and a second spraying hole 410. The bottom surface of the rotating arm 47 has a downwardly protruding connecting cylinder 411. The connecting cylinder is inserted into the supporting protrusion, and the connecting cylinder and the supporting protrusion rotate horizontally in cooperation, thereby ensuring a secure connection and stable rotation between the rotating spraying arm 44 and the supporting protrusion 45. The rotating arm is connected to the branch water channel through the supporting protrusion.

[0053] The rotating spray arm 44 is connected to and detachably connected to the branch waterway 417.

[0054] The main waterway 41 and multiple branch waterways 417 are connected in an I-shape.

[0055] The central column 42 is located at the center of the top surface of the main waterway 41.

[0056] The horizontal height of the central column 42 is higher than the horizontal height of the rotating spray arm 44.

[0057] The rotating arm 47 is formed by connecting the upper arm 471 and the lower arm 472 together. The shape and size of the upper arm 471 and the lower arm 472 are matched.

[0065] The outer wall of the rotating annular protrusion 414 is provided with a sealing annular protrusion 416, thereby sealing the gap between the connecting cylinder and the supporting protrusion and preventing water leakage and insufficient water pressure in the rotating arm.

[0066] The working principle of this utility model is as follows: Before this utility model starts working, the user first pours water into the water tank 3 until a certain amount of water is reached. Then, the user inverts multiple baby bottles onto the bottle rack and then puts the bottle rack together with the baby bottles into the inner liner 6. At this time, the bottle mouths face down and the spray column 48 extends into the baby bottles. After that, the bottle caps, nipples and other baby products are placed on top of the bottle rack, and finally the machine cover 2 is closed.

[0067] When this utility model starts working, the user presses the switch on the display screen, and the water inlet pump 9 starts first. The water inlet pump 9 begins to draw water from the water tank 3 into the inner tank 6. The water in the water tank 3 enters the inner tank 6 through the water inlet pump 9, the first water inlet 12, and the water inlet 69 until the water in the inner tank 6 reaches a certain volume. Then the washing pump starts and begins to draw water from the inner tank 6. Under the huge suction force, the water in the inner tank 6 enters the main water channel 41 through the water outlet 610 and the water inlet 413 in sequence. The high-pressure water then enters the branch water channel 417 and the central column 42. Finally, the water is sprayed out through the first spray hole 49 on the rotating spray arm, the second spray hole 410 on the spray column 48, and the third spray hole 419. Driven by the water flow, the rotating spray arm automatically rotates and sprays water. The water sprayed from the first spray hole 49 rinses the outer wall of the bottle, while the water sprayed from the first spray hole 49, the second spray hole 410, and the third spray hole 419 rinses the inner wall of the bottle. The fourth spray hole of the central column 42 rinses the bottle cap and nipple on the top of the bottle holder. After rinsing the bottle, the bottle spraying mechanism 4 returns all the water to the bottom of the inner liner 6.

[0068] Next, the control panel controls the heating element 7 to heat up, and the heating element 7 heats the water in the inner tank 6. The water in the inner tank 6 gradually turns into high-temperature steam. The high-temperature steam sterilizes the bottles, caps and nipples on the bottle rack. The high-temperature steam in the inner tank 6 is discharged from the exhaust hole 21 on the cover 2. After the steam condenses into water, it flows back down to the bottom of the inner tank 6.

[0069] After the baby bottles and other parts are steam sterilized, the control board controls the drain pump 81 to start draining. The drain pump 81 draws the water out of the inner tank 6. The water in the inner tank 6 passes through the outlet 610, the second water inlet 13, the third water inlet 14, and the drain outlet (not shown in the figure) in sequence and is discharged from the baby bottle washing machine.

[0070] Then, the control panel controls the drying assembly 5 to start, the fan 51 and the heating device 53 to start, the drying assembly 5 blows hot air into the inner tank 6, the hot air enters the inner tank 6 from the air inlet 611, and the hot air begins to dry the moisture on the bottle, bottle cap and nipple.

[0071] After the bottles and other parts are dried, the control panel stops the entire bottle washing machine, and the user can then open the cover 2 and take out the bottle rack and bottles from the inner tank 6.
