[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0047] In this document, references to "embodiment" or "implementation" mean that a particular feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0048] like Figures 1 to 9 This application provides a rotary spray arm 320b and a container cleaning machine 10b. The rotary spray arm 320b can be applied to the container cleaning machine 10b, which can be understood as the container cleaning machine 10b including the rotary spray arm 320b. The container cleaning machine 10b includes a main water pipe 410b and a shelf 220b. The rotary spray arm 320b can be connected to and communicate with the main water pipe 410b, and the rotary spray arm 320b can rotate around the main water pipe 410b. The shelf 220b is used to place containers such as baby bottles. Along the length direction of the main water pipe 410b, the rotary spray arm 320b is disposed below the shelf 220b, and the rotary spray arm 320b can spray cleaning fluid to clean the containers such as baby bottles placed on the shelf 220b. In an optional embodiment, the shelf 220b can be the lower shelf of the container cleaning machine 10b, and the rotary spray arm 320b can be the lower rotary spray arm of the container cleaning machine 10b. Understandably, the container washing machine 10b may also include other components, such as an upper shelf, an upper rotating spray arm, etc.

[0049] like Figures 1 to 5 The 320b rotary spray arm can be used in container cleaning machines, such as... Figure 9 The container washer 10b shown is capable of cleaning containers, such as baby bottles, using a cleaning solution, such as water. The rotating spray arm 320b includes a rotating part 3210 and at least three spray arm bodies 3220, which are fixedly connected, for example, integrally formed. Exemplarily, the at least three spray arm bodies 3220 are spaced apart on the periphery of the rotating part 3210 and communicate with the rotating part 3210, or in other words, the at least three spray arm bodies 3220 are connected to the outer periphery of the rotating part 3210.

[0050] In one optional embodiment, at least three spray arm bodies 3220 are equally spaced around the periphery of the rotating part 3210. When the rotating spray arm 320b includes three spray arm bodies 3220, adjacent pairs of the three spray arm bodies 3220 form an included angle of 120°. This application uses three spray arm bodies 3220 as an example for illustrative purposes. It is understood that the number of spray arm bodies 3220 can also be four, five, or other numbers.

[0051] The rotating part 3210 is rotatable around the main water pipe 410b of the container washing machine 10b. Exemplarily, the rotating spray arm 320b includes a through hole 3230 through which the main water pipe 410b passes, allowing the rotating part 3210 to be fitted onto the outside of the main water pipe 410b. The rotating spray arm 320b also includes a connecting structure 3250, which is integrally formed with the rotating part 3210. After the rotating part 3210 is fitted onto the main water pipe 410b, the connecting structure 3250 is connected to a connecting structure on the main water pipe 410b, such as a protruding ring, and the rotating spray arm 320b is rotatable around the main water pipe 410b.

[0052] For example, the rotating part 3210 is hollow inside, so that the through hole 3230 communicates with the channel 3240 of each spray arm body 3220 through the rotating part 3210. The through hole 3230 also communicates with the internal channel of the main water pipe 410b, which can be connected to the cleaning fluid and transported to the rotating spray arm 320b. The main water pipe 410b may be connected to a housing, which can be filled with cleaning fluid.

[0053] For example, any spray arm body 3220 is provided with at least two sets of spray holes (A11 and B11; or, A12 and B12; or, A13 and B13). Each set of spray holes (A11, B11, A12, B12, A13, B13) includes multiple spray holes 3201, and at least two spray holes 3201 in at least one set of spray holes have different spray directions. This allows at least two spray holes 3201 in at least one set of spray holes to spray cleaning fluid in multiple directions during the spraying process, thereby achieving multi-directional water jet spraying and improving the cleaning effect.

[0054] For example, the innermost (closest to the rotating part 3210) spray hole 3201 of each group of spray holes (A11, B11, A12, B12, A13, B13) has an outward tilting angle. In an optional embodiment of this application, the distance between the corresponding positions of at least two groups of spray holes on the same spray arm body 3220 and the rotating part 3210 is different, and the distance between the corresponding positions of multiple spray holes 3201 in a group of spray holes on the same spray arm body 3220 and the rotating part 3210 is different; wherein, the spray direction of the spray hole 3201 closest to the rotating part 3210 in any group of spray holes is tilted away from the rotating part 3210. This can enhance the rinsing effect on the inside of the tilted container.

[0055] For example, the spray directions of all spray holes 3201 in any group of spray holes are different, so that the direction of the water jets generated by all spray holes 3201 in any group of spray holes during the spraying of cleaning fluid is different. For example, the spray hole arrangement can provide water jet coverage to the container above it in multiple directions, such as 9 or 18, during the rotation of the rotating spray arm 320b.

[0056] For example, the groups of spray holes on any spray arm body 3220 are arranged along the length direction F4 of the spray arm body 3220, and the spray holes 3201 in any group of spray holes are arranged along the length direction F4 of the spray arm body 3220. In one case, the spray holes 3201 in any group of spray holes are staggered along the length direction F4 of the spray arm body 3220. The staggered arrangement can be understood as the distance between each spray hole 3201 in any group of spray holes and the edge of the side of the spray arm body 3220 is different.

[0057] For example, the spray arm body 3220 includes a first spray arm body 3221, a second spray arm body 3222, and a third spray arm body 3223; the first spray arm body 3221 is provided with a first group of spray holes A11 near the rotating part 3210 and a second group of spray holes B11 away from the rotating part 3210; the second spray arm body 3222 is provided with a third group of spray holes A12 near the rotating part 3210 and a fourth group of spray holes B12 away from the rotating part 3210; the third spray arm body 3223 is provided with a fifth group of spray holes A13 near the rotating part 3210 and a sixth group of spray holes B13 away from the rotating part 3210.

[0058] For example, the first set of nozzles A11 is located at the first position P1 of the first spray arm body 3221, the third set of nozzles A12 is located at the third position P3 of the second spray arm body 3222, and the fifth set of nozzles A13 is located at the fifth position P5 of the third spray arm body 3223; the first position P1, the third position P3, and the fifth position P5 are arranged around the rotating part 3210, and the corresponding parts of the first position P1, the third position P3, and the fifth position P5 are spaced at the same distance from the rotating part 3210. Alternatively, it can be understood that the first position P1, the third position P3, and the fifth position P5 together define a first ring R1 around the rotating part 3210.

[0059] The second set of nozzles B11 is located at the second position P2 of the first spray arm body 3221, the fourth set of nozzles B12 is located at the fourth position P4 of the second spray arm body 3222, and the sixth set of nozzles B13 is located at the sixth position P6 of the third spray arm body 3223. The second position P2, the fourth position P4, and the sixth position P6 are arranged around the rotating part, and the corresponding parts of the second position P2, the fourth position P4, and the sixth position P6 are spaced the same from the rotating part 3210. Alternatively, it can be understood that the second position P2, the fourth position P4, and the sixth position P6 together define a second ring R2 around the rotating part 3210, the second ring R2 is spaced from the first ring R1, and the second ring R2 surrounds the first ring R1.

[0060] Combination Figure 6 , Figure 7 , Figure 8 and Figure 9 All spray holes 3201 of the rotating spray arm 320b are oriented towards the shelf 220b. When spraying cleaning fluid, all spray holes 3201 of the rotating spray arm 320b can act on containers on the shelf 220b, such as the first baby bottle 21A and the second baby bottle 21B, to clean the first baby bottle 21A and the second baby bottle 21B. In an optional embodiment, the coverage area of ​​the spray holes 3201 is aligned with the mouth of the container, such as the baby bottle, to ensure that the spray holes 3201 can spray into the container, such as the baby bottle, when a cleaning column is generated by spraying cleaning fluid.

[0061] Among them, the spray holes 3201 in the first group of spray holes A11, the third group of spray holes A12, and the fifth group of spray holes A13 all face the seventh position P7 of the shelf 220b; the spray holes 3201 in the second group of spray holes B11, the fourth group of spray holes B12, and the sixth group of spray holes B13 all face the eighth position P8 of the shelf 220b; the seventh position P7 and the eighth position P8 are different.

[0062] When the rotating spray arm 320b is spraying cleaning fluid, the cleaning fluid sprayed from the spray holes 3201 in the first group of spray holes A11, the spray holes 3201 in the third group of spray holes A12, and the spray holes 3201 in the fifth group of spray holes A13 can act on the seventh position P7 of the shelf 220b; the cleaning fluid sprayed from the spray holes 3201 in the second group of spray holes B11, the spray holes 3201 in the fourth group of spray holes B12, and the spray holes 3201 in the sixth group of spray holes B13 can act on the eighth position P8 of the shelf 220b.

[0063] In one scenario, the eighth position P8 is located at a corner of the shelf 220b. For example, if the shelf 220b has four corner positions, it has four eighth positions P8. Each eighth position P8 can hold and limit a container, such as the second baby bottle 21B. The seventh position P7 is located between two adjacent eighth positions P8. For example, if the shelf 220b has four seventh positions P7, each P7 can hold and limit a container, such as the first baby bottle 21A. Thus, during the rotation of the rotating spray arm 320b, when all the spray holes of the rotating spray arm 320b are spraying cleaning fluid, the cleaning fluid sprayed from the spray holes 3201 in the first group of spray holes A11, the spray holes 3201 in the third group of spray holes A12, and the spray holes 3201 in the fifth group of spray holes A13 can act on multiple, for example, four first baby bottles 21A to clean the first baby bottles 21A; the cleaning fluid sprayed from the spray holes 3201 in the second group of spray holes B11, the spray holes 3201 in the fourth group of spray holes B12, and the spray holes 3201 in the sixth group of spray holes B13 can act on multiple, for example, four second baby bottles 21B to clean the second baby bottles 21B. Figure 7 As shown, the cleaning liquid sprayed from the spray hole 3201 in the first group of spray holes A11, the spray hole 3201 in the third group of spray holes A12, or the spray hole 3201 in the fifth group of spray holes A13 can generate a first column A01, which can enter the interior of the first bottle 21A from the opening of the container, such as the first baby bottle 21A. Figure 8 As shown, the cleaning liquid sprayed from the spray hole 3201 in the second group of spray holes B11, or the spray hole 3201 in the fourth group of spray holes B12, or the spray hole 3201 in the sixth group of spray holes B13 can generate a second column B01, which can enter the interior of the second bottle 21B from the bottle opening of the container, such as the second bottle 21B.

[0064] It is also understandable that during the rotation of the rotating spray arm 320b, when all the spray holes of the rotating spray arm 320b are spraying cleaning fluid, the cleaning fluid sprayed from the spray holes 3201 in the first group of spray holes A11, the spray holes 3201 in the third group of spray holes A12, and the spray holes 3201 in the fifth group of spray holes A13 are confined in the first ring R1; the cleaning fluid sprayed from the spray holes 3201 in the second group of spray holes B11, the spray holes 3201 in the fourth group of spray holes B12, and the spray holes 3201 in the sixth group of spray holes B13 are confined in the second ring R2.

[0065] For example, the arrangement of the spray holes 3201 in the first group of spray holes A11, the third group of spray holes A12, and the fifth group of spray holes A13 is the same. For instance, the positions of the spray holes 3201 in the first group of spray holes A11, the third group of spray holes A12, and the fifth group of spray holes A13 are the same. In other optional embodiments, the arrangement of the spray holes 3201 in the first group of spray holes A11, the third group of spray holes A12, and the fifth group of spray holes A13 can also be different.

[0066] For example, the arrangement of the spray holes 3201 in the second group of spray holes B11, the fourth group of spray holes B12, and the sixth group of spray holes B13 is the same. For instance, the positions of the spray holes 3201 in the second group of spray holes B11, the fourth group of spray holes B12, and the sixth group of spray holes B13 are the same. In other optional embodiments, the arrangement of the spray holes 3201 in the second group of spray holes B11, the fourth group of spray holes B12, and the sixth group of spray holes B13 can also be different.

[0067] For example, each spray arm body 3220 has at least one power hole 3202 for providing rotational torque below it. The power hole 3202 is inclined relative to the central axis L11 of the rotating spray arm 320b so as to drive the spray arm body 3220 to rotate by reaction force during the spraying of cleaning fluid by the power hole 3202, wherein the direction of spraying cleaning fluid by the power hole 3202 is opposite to the rotation direction of the spray arm body 3220.

[0068] The rotary spray arm and container cleaning machine provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this application. Therefore, the content of this specification should not be construed as a limitation of this application.
