[0031] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0032] In one embodiment of the cleaning machine of this utility model, the cleaning machine specifically includes a spray arm structure for washing baby bottles. The spray arm structure can be used to clean items inside the cleaning machine, ensuring the cleaning range and increasing the cleaning effect.

[0033] Specifically, please refer to Figures 1 to 6 The bottle washing machine spray arm structure includes a water supply pipe 100, a first rotating spray arm 200, and a second rotating spray arm 300. The bottom end of the water supply pipe 100 has a water inlet 101. The water supply pipe 100 has a first mounting position 102 and a second mounting position 103 along its axial direction. Both the first mounting position 102 and the second mounting position 103 have water outlets 104 that communicate with the interior of the water supply pipe 100. The first rotating spray arm 200 is rotatably fitted onto the first mounting position 102, and the second rotating spray arm 300 is rotatably fitted onto the second mounting position 103. A first water flow channel 201 is provided inside the first rotating spray arm 200, and a second water flow channel 301 is provided inside the second rotating spray arm 300. The first water flow channel 201 and the second water flow channel 301 are connected to the water supply pipe 100 through corresponding water outlets 104. The top side of the first rotating spray arm 200 is provided with a first water nozzle 202, and the water flow sprayed from the first water nozzle 202 drives the first rotating spray arm 200 to rotate. The top side of the second rotating spray arm 300 is provided with a second water nozzle 302, and the water flow sprayed from the second water nozzle 302 drives the second rotating spray arm 300 to rotate.

[0034] In the above embodiment, the bottom end of the water supply pipe 100 can be fitted onto the water supply pipe of the cleaning machine, so the water supply system of the cleaning machine can input high-pressure cleaning water into the water supply pipe 100. When cleaning the objects inside the cleaning machine, when high-pressure cleaning water is input into the water supply pipe 100, the water flow in the water supply pipe 100 will enter the first water flow channel 201 of the first rotating spray arm 200 and the second water flow channel of the second rotating spray arm 300 from the outlet 104 of the first mounting position 102 and the second mounting position 103, respectively, and then spray upward from the first spray nozzle 202 and the second spray nozzle 302, respectively, to clean the objects inside the cleaning machine. During the spraying process, due to the reaction force of the water flow, the first spray nozzle 202 and the second spray nozzle 302 push the first rotating spray arm 200 and the second rotating spray arm 300 to rotate, thus increasing the cleaning range of the second rotating spray arm 300, making the cleaning range larger and the cleaning effect better.

[0035] Furthermore, refer to Figures 1 to 6 The first mounting position 102 has a support ring 105 at its upper end, and the first rotating spray arm 200 has a support part 203. The support part 203 is supported on the support ring 105, allowing the first rotating spray arm 200 to be rotatably mounted on the outer ring of the water supply pipe 100. A sealing ring 210 extends downward from the bottom of the first rotating spray arm 200. The sealing ring 210 fits around the outer ring of the water supply pipe 100, ensuring that the outlet 104 is completely located within the first water flow channel 201 of the first rotating spray arm 200. This achieves a sealing effect, preventing water from spraying out from the gap connecting the first rotating spray arm 200 and the water supply pipe 200.

[0036] The lower end of the second mounting position 103 is provided with a support sleeve 110, and the bottom end of the second rotating spray arm 300 is supported on the support sleeve 110. A limiting collar 120 is also fitted on the water pipe 100 to limit it to the top side of the second rotating spray arm 300. This allows the second rotating spray arm 300 to be rotatably connected to the second mounting position 102.

[0037] Furthermore, refer to Figure 3 and Figure 4 The bottom end of the first mounting position 102 also has a raised ring 106, which forms a sealing position with the sealing ring 210. The raised ring 106 further increases the sealing performance with the sealing ring 210 and also reduces the friction force when the first rotating spray arm 200 rotates, making the rotation of the first rotating spray arm 200 smoother.

[0038] Furthermore, the bottom end of the second rotary spray arm 300 is also provided with a downwardly extending sealing sleeve 303. Specifically, the sealing sleeve 303 can increase the sealing between the second rotary spray arm 300 and the outside of the water supply pipe 100, and can prevent excessive cleaning water from overflowing from the position of the second mounting 103.

[0039] Reference Figure 3 and Figure 4 The upper end of the second mounting position 103 is provided with a support step 107, and the upper end of the second rotating spray arm 300 is supported on the support step 107. In this embodiment, the second rotating spray arm 300 is rotatably connected to the second mounting position 103.

[0040] Furthermore, refer to Figures 1 to 4 The outer side of the limiting collar 120 is also evenly distributed with a plurality of support arms 121, and the support arms 121 are also provided with a plurality of locking positions 122. In this embodiment, the object to be cleaned can be isolated by the support arms 121 to prevent the object to be cleaned from directly contacting the second rotating spray arm 300 and thus hindering the rotation of the second rotating spray arm 300.

[0041] Furthermore, refer to Figure 3 and Figure 6 The second rotating spray arm 300 also has a support protrusion 304 on its top side, and the limiting collar 120 is supported on the support protrusion 304. In this embodiment, the limiting collar 120 can be supported by the support protrusion 304, which can further reduce the contact area between the second rotating spray arm 300 and the limiting collar 120, reduce friction, and make the rotation smoother. Preferably, the top surface of the support protrusion 304 can be an arc surface, which can achieve line contact between the second rotating spray arm 300 and the limiting collar 120.

[0042] Furthermore, a retaining ring is provided on the outside of the water pipe 100, and a retaining collar 120 extends downward with an elastic arm, the elastic arm having a retaining buckle that engages with the retaining ring.

[0043] Furthermore, refer to Figure 6 The second rotating spray arm 300 includes a collar 310, and multiple spray arms 320 extend outward from the outer side of the collar 310. Each spray arm 320 has an upwardly extending water column 330 at its free end. The top side of the water column 330 has multiple water outlets facing different directions, and the multiple water outlets form a second water nozzle 302.

[0044] Furthermore, in order to dry baby bottles and other items while washing them, the spray arm structure of the baby bottle washing machine in this embodiment also includes an air duct 400, as detailed in the following reference. Figure 1 , Figure 2 and Figure 7The air duct 400 is located between the first rotating spray arm 200 and the second rotating spray arm 300. The air duct 400 includes an annular pipe 410, with an air inlet pipe 420 extending from its outer side. The air inlet pipe 420 is used to connect to the hot air device of the cleaning machine. Multiple ribs 411 extend from the inner ring of the annular pipe 410, with one end of each rib 411 connected to the same connecting sleeve 430. The connecting sleeve 430 is fitted onto the water supply pipe 100, thereby allowing the air duct 400 to be fixed to the water supply pipe 100. The bottom end of the second rotating spray arm 300 is supported on the connecting sleeve 430. Additionally, the connecting sleeve 430 also limits the movement of the first rotating spray arm 200, preventing it from shifting upwards.

[0045] Furthermore, refer to Figure 1 , Figure 3 and Figure 6 The water flow output from the water supply pipe 100 pushes the first rotating spray arm 200 and the second rotating spray arm 300 to rotate in opposite directions. Specifically, the first spray nozzle 202 and the second spray nozzle 302 have different orientations, so the first rotating spray arm 200 and the second rotating spray arm 300 are subjected to different forces, which can make the first rotating spray arm 200 and the second rotating spray arm 300 rotate in opposite directions.

[0046] The bottom side of the second rotating spray arm 300 is also provided with an elastic lever 340, which is located between two adjacent ribs 411. The rotating first rotating spray arm 200 pushes the elastic lever 340, causing the second rotating spray arm 300 to rotate in the same direction. In this embodiment, when the first rotating spray arm 200 rotates, it can push the second rotating spray arm 300 to rotate in the same direction when it touches the elastic lever 340. When the elastic lever 340 touches the rotating spray arm 200, it deforms elastically, causing the elastic lever 340 to disengage from the rotating spray arm 200. Therefore, the second elastic spray arm 300 rotates in the opposite direction under the action of water flow. This cycle continues, so that the second rotating spray arm 300 always rotates back and forth within a fixed range, thereby increasing the cleaning frequency of the area and improving the cleaning efficiency.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
