Description

Technical Field

[0001] This utility model relates to the technical field of baby bottle washing machines, and in particular to a waterproof structure for a baby bottle washing machine. Background Technology

[0002] Current bottle washing machines consist of a main body, an inner tank, a top cover, a 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. When the rotating rinsing arm assembly sprays water to wash the bottles inside the inner tank, the water sprayed by the rotating rinsing arm assembly will spray onto the inner wall of the top cover. The water will flow down the inner wall of the top cover and out through the gap between the top cover and the inner tank, and then flow to the top of the main body, resulting in water accumulation on the top of the main body. This water accumulation can easily breed bacteria and is inconvenient for users. Utility Model Content

[0003] The purpose of this invention is to provide a waterproof structure for a baby bottle washing machine with good waterproof performance.

[0004] The purpose of this utility model is achieved as follows: A waterproof structure for a baby bottle washer includes a housing, an inner liner, a lid, and a bottle spraying mechanism. The inner liner is located inside the housing, with an opening at its top. The bottle spraying mechanism is located inside the inner liner. The lid is detachably positioned over the opening of the inner liner. A waterproof annular groove is formed around the circumference of the opening, and the lower edge of the lid rests within this groove. Multiple drainage notches are spaced apart on the sidewalls of the waterproof annular groove, connecting it to the inner liner. This invention, by providing a waterproof annular groove and drainage notches at the opening of the inner liner, allows water sprayed onto the inner wall of the lid during the bottle spraying mechanism to flow back into the inner liner, preventing water accumulation on the top of the housing and providing convenience for the user.

[0005] The opening is surrounded by an outer waterproof annular groove along its circumference, located outside the inner waterproof annular groove. This invention features a reasonable structural design, ensuring that even if the inner waterproof annular groove is full, water will overflow into the outer waterproof annular groove, effectively preventing water from flowing onto the top surface of the casing.

[0006] The outer waterproof annular groove is deeper than the inner waterproof annular groove. Therefore, the water storage capacity of the outer waterproof annular groove is greater than that of the inner waterproof annular groove, allowing the outer waterproof annular groove to hold more water and preventing water from flowing to the top of the casing.

[0007] The thickness of the lower edge of the cover is less than the width of the inner waterproof annular groove. Therefore, the lower edge of the cover will not occupy too much volume of the inner waterproof annular groove, allowing the inner waterproof annular groove to hold more water and preventing it from easily overflowing into the outer waterproof annular groove.

[0008] The horizontal height of the drainage gap is lower than the horizontal height of various locations in the inner waterproof annular groove, which causes the water in the inner waterproof annular groove to flow towards the drainage gap and then out of the inner waterproof annular groove.

[0009] The opening is surrounded by a lower outward flange, on which the outer waterproof annular groove and the inner waterproof annular groove are located. This invention features a reasonable structural design, which is beneficial for designing the outer and inner waterproof annular grooves.

[0010] The lower edge of the cover has an upper outward flange, which sits on the lower outward flange to position and support the cover.

[0011] The bottom surface of the upper outward-turned edge is provided with a positioning protrusion ring. The positioning protrusion is located on the outer side of the lower edge of the cover, and the positioning protrusion ring sits in the outer waterproof annular groove, thereby achieving positioning and support of the cover.

[0012] The beneficial effects of this utility model are as follows: This invention features an inner waterproof annular groove and a drainage notch at the opening of the inner liner, allowing water sprayed onto the inner wall of the lid during the bottle washing mechanism to flow back into the inner liner, thus preventing water accumulation on the top of the casing. This makes it convenient for users and provides excellent waterproofing. Attached Figure Description

[0037] 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.

[0038] 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.

[0039] The depth of the outer waterproof annular groove 63 is greater than the depth of the inner waterproof annular groove 61.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] The bottom surface of the upper outward flange 64 is provided with a positioning protrusion ring 66. The positioning protrusion is located on the outer side of the lower edge of the cover 2.

[0045] The top surface of the cover 2 is provided with an exhaust hole 21, and the inner top wall of the cover 2 is connected to a baffle plate 22. There is an exhaust gap between the baffle plate 22 and the inner top wall of the cover 2, and the baffle plate 22 is located directly below the exhaust hole 21.

[0046] The bottle spraying mechanism 4 includes a main water channel 41 and multiple branch water channels 417. The bottom surface of the main water channel 41 has an inlet 413, and the top surface of the main water channel 41 has a central column 42. One end of each branch water channel 417 is connected to the main water channel 41. Multiple rotating spraying arms 44 are horizontally rotatable on each branch water channel 417. The other end of each branch water channel 417 has a supporting protrusion 45. A rotating spraying arm 44 is horizontally rotatable on the supporting protrusion 45. 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.

[0047] The rotating spray arm 44 is connected to and detachably connected to the branch waterway 417.

[0048] The main waterway 41 and multiple branch waterways 417 are connected in an I-shape.

[0049] The central column 42 is located at the center of the top surface of the main waterway 41.

[0050] The horizontal height of the central column 42 is higher than the horizontal height of the rotating spray arm 44.

[0051] 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. The spray column 48 is located on the top surface of the upper arm 471. The lower end of the spray column 48 is connected to the rotating arm 47.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.
