[0035] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application.

[0036] Refer to the following Figures 1 - 9 Describe the spray assembly 100 according to the embodiments of the present application. The spray assembly 100 can be used for spraying water to clean the items to be cleaned (such as tableware, cookware, etc.) through the water sprayed by the spray assembly 100. The spray assembly 100 can be applied to cleaning equipment and used as a spraying device in the cleaning equipment for spraying cleaning liquid onto the items to be cleaned, so as to improve the cleaning effect of the cleaning equipment on the items to be cleaned. Among them, the cleaning equipment can be a dishwasher, etc.

[0037] The spray assembly 100 according to the embodiments of the present application includes: a main body part 1 and a cap body 2. The main body part 1 is provided with a water supply flow path, and the water supply flow path can be communicated with a water supply source. The water supply source can supply cleaning liquid (such as water, etc.) to the water supply flow path of the main body part 1.

[0038] As Figure 1 shown, the water supply flow path includes a main water path 101 and a branch water path 102. The main water path 101 is used for supplying water to the branch water path 102, and the branch water path 102 extends circumferentially around the first axis X and gradually extends away from the main water path 101, thereby forming a water path structure extending in a spiral shape for the branch water path 102, so that the water supply flow path can output a water flow flowing obliquely relative to the first axis X, that is, the flowing direction of the water flow discharged from the water outlet port 12 of the branch water path 102 is arranged obliquely relative to the first axis X.

[0039] Refer to Figure 1 , the cap body 2 is connected to the main body part 1 to form a water outlet cavity 10. The water outlet cavity 10 is communicated with the water outlet port 12 of the branch water path 102. The water flow output from the water outlet port 12 can converge in the water outlet cavity 10, and the cap body 2 is provided with a water outlet hole 23 communicated with the water outlet cavity 10. The water flow in the water outlet cavity 10 can be further discharged outwards through the water outlet.

[0040] Among them, Figure 1 The arrows shown in are schematic diagrams of the flowing direction of the water flow in the water supply flow path.

[0041] It can be understood that since the water flow flowing into the water outlet cavity 10 through the water outlet port 12 is conveyed obliquely relative to the first axis X, a rotating conveying water flow can be formed in the water outlet cavity 10, that is, a vortex is formed in the water outlet cavity 10.

[0042] Further, since the water supply source can continuously supply water to the spraying assembly 100, a certain water pressure is generated in the water outlet cavity 10. Driven by the water pressure, the rotating water flow can be ejected from the water outlet holes 23 to the outside of the spraying assembly 100. At the same time, due to the rotational conveyance of the water flow in the water outlet cavity 10, the water ejected outward through the water outlet holes 23 will be thrown out along the tangent direction of the water column under the action of centrifugal force, thereby forming a water column that spreads out in all directions, which can increase the coverage area of the water column ejected by the spraying assembly 100, and further improve the cleaning effect on the items to be cleaned by increasing the coverage area of the water column ejection.

[0043] It should be noted that currently, in cleaning equipment (such as dishwashers, etc.), the cleaning function is realized by spraying a water column on the items to be cleaned. In the related art, usually, the cleaning effect is improved by increasing the washing pressure of the water column, but the coverage area of the water column is small, and it cannot achieve a good cleaning effect on different types of tableware (such as deep-mouthed cups). That is to say, only by increasing the output pressure of the water column, some types of tableware cannot be fully cleaned, which affects the cleaning effect of the cleaning equipment on the items to be cleaned, such as deep-mouthed cups with a relatively large depth.

[0044] In the present application, the water column ejected by the spraying assembly 100 can gradually spread outward, thereby increasing the coverage area of the water column, enabling the water column to fully cover the items to be cleaned, and improving the cleaning ability of the spraying assembly 100. Thus, the spraying assembly 100 improves the cleaning ability of the cleaning equipment by increasing the ejection coverage area of the water column. That is to say, the spraying assembly 100 in the present application can be used to effectively clean the items to be cleaned that require a relatively large cleaning coverage area (such as deep-mouthed cups, etc.).

[0045] Such as Figure 5 and Figure 6 As shown, in some embodiments of the present application, the main body 1 has a cavity, and a water dividing rib 13 is provided in the cavity. The water dividing rib 13 and the wall surface of the cavity define a water dividing channel 102.

[0046] It can be understood that the above-mentioned water dividing channel 102 can be separated and formed in the cavity by the water dividing rib 13. The water flow flowing to one side of the water dividing rib 13 through the main water channel 101 can be divided at the water dividing rib 13 and flow into the water dividing channel 102, so as to guide the water flow into the water dividing channel 102 through the water dividing rib 13.

[0047] Combined with Figure 1 、 Figure 5 and Figure 6 As shown, in a further embodiment of the present application, the water dividing rib 13 and the wall surface of the cavity define two water dividing channels 102. The two water dividing channels 102 are respectively formed on both sides of the water dividing rib 13, and the two water dividing channels 102 are symmetrically arranged with respect to the first axis X.

[0048] Thus, the two water diversion channels 102 can play the same guiding role for the water flow, and when the two water diversion channels 102 send water to the side of the water outlet cavity 10 respectively, the water flows flowing into the water outlet cavity 10 from the two water diversion channels 102 can act together to form a vortex, which helps to improve the water flow effect in the water outlet cavity 10 (such as: increasing the flow velocity, etc.).

[0049] As Figure 1 shown, in some embodiments of the present application, the cap body 2 is formed with an installation cavity 201 that is open to one side of the main body portion 1. When the cap body 2 is connected and cooperated with the main body portion 1, at least part of the main body portion 1 extends into the installation cavity 201, and the end portion of the main body portion 1 forming the water outlet port 12 and the installation cavity 201 jointly define the water outlet cavity 10. The water flow flowing into the water outlet cavity 10 through the water outlet port 12 can form a vortex in the water outlet cavity 10, so that the water in the water outlet cavity 10 has a rotational movement tendency when discharged outward through the water outlet holes 23, and the coverage area when the water column is ejected can be increased.

[0050] It can be understood that the cap body 2 covers the main body portion 1, and the end portion of the main body portion 1 and the wall surface of the installation cavity 201 define the water outlet cavity 10. The water flow discharged from the water outlet port 12 on the main body portion 1 can flow into and converge in the water outlet cavity 10, and the water flow in the water outlet cavity 10 can be further discharged outward through the water outlet holes 23.

[0051] Referring to Figure 1 and Figure 8 shown, the inner peripheral wall of the installation cavity 201 is configured as an arc surface, so that the flow resistance of the water flow in the water outlet cavity 10 can be reduced, and a good guiding effect can be played on the flow direction of the water flow, so as to facilitate the formation of a vortex in the water outlet cavity 10.

[0052] Wherein, the cross-section of the installation cavity 201 in the axial direction of the first axis X is circular. Configuring the inner peripheral wall of the installation cavity 201 as a wall surface extending in a circumferential direction can reduce the flow resistance of the water flow, and can play a guiding role for the airflow flowing into the water outlet cavity 10 from the water diversion channel 102.

[0053] In some embodiments of the present application, the central axis of the water outlet hole 23 is collinear or parallel to the first axis X. When the central axis of the water outlet hole 23 is collinear with the first axis X, the flow direction of the water flow in the water outlet cavity 10 can rotate around the first axis X. At the same time, referring to Figure 1 and Figure 8 shown, the water outlet hole 23 is formed on the surface of the cap body 2 opposite to the open side of the installation cavity 201, so that the water flow ejected from the water outlet hole 23 can be thrown outward along the tangential direction of the water column (i.e., away from the first axis X side), ensuring the coverage area of the water column ejected from the water outlet hole 23.

[0054] It can be understood that when the central axis of the water outlet hole 23 is parallel to the first axis X, the water column discharged through the water outlet hole 23 also has a tendency to diffuse in the tangential direction, which can ensure the coverage range of the water column sprayed at the water outlet hole 23.

[0055] As Figure 2 , Figure 3 and Figure 9 shown, in some embodiments of the present application, the outer peripheral wall of the main body portion 1 is attached to the inner peripheral wall of the installation cavity 201 to prevent the water in the water outlet cavity 10 from flowing out through the gap between the main body portion 1 and the cap body 2. The outer peripheral wall of the main body portion 1 is provided with a sliding groove 11, and the sliding groove 11 extends along the circumferential direction of the main body portion 1 and towards the water outlet side of the main body portion 1, so as to form a helically extending sliding groove 11 on the outer periphery of the main body portion 1.

[0056] Referring to Figure 2 , Figure 3 and Figure 8 shown, the inner peripheral wall of the cap body 2 is provided with a positioning protrusion 21, and the positioning protrusion 21 protrudes inward (i.e., towards the side close to the first axis X) from the inner peripheral wall. When the cap body 2 is connected and cooperated with the main body portion 1, the positioning protrusion 21 is arranged in the sliding groove 11 and is in sliding cooperation with the sliding groove 11. Thus, the cap body 2 can rotate relative to the main body portion 1 through the sliding cooperation between the positioning protrusion 21 and the sliding groove 11 to adjust the dimension of the water outlet cavity 10 in the axial direction of the first axis X.

[0057] Combined with Figure 2 and Figure 3 shown, the positioning protrusion 21 is arranged in the sliding groove 11, and the positioning protrusion 21 can slide along the extending direction of the sliding groove 11. When the positioning protrusion 21 and the sliding groove 11 are cooperated, it can prevent the cap body 2 from being disengaged from the main body portion 1 and improve the connection reliability between the cap body 2 and the main body portion 1.

[0058] It can be understood that the water flow in the water outlet cavity 10 rotates and flows. Referring to Figure 3 , when the dimension of the water outlet cavity 10 in the axial direction increases, the space of the water outlet cavity 10 becomes larger, and the heat dissipation effect of the water column sprayed out through the water outlet hole 23 is better, which can increase the coverage area of the water column sprayed by the spraying assembly 100; referring to Figure 2 , when the dimension of the water outlet cavity 10 in the axial direction decreases, the space of the water outlet cavity 10 decreases, and the water column sprayed out through the water outlet hole 23 will be relatively concentrated (compared with the water outlet cavity 10 with a larger space).

[0059] Thus, the spray wheel assembly in the present application can adjust the water column spraying mode according to the cleaning requirements, so that the spraying assembly 100 can meet the cleaning requirements of various types of items to be cleaned, thereby achieving the best washing effect and improving the application range of the spraying assembly 100.

[0060] As Figure 2As shown, in some embodiments of the present application, a limiting portion 22 is provided on the inner peripheral wall of the cap body 2. The limiting portion 22 is used to abut and position against the end of the main body portion 1 close to the water outlet hole 23, so as to limit the further rotation of the cap body 2 relative to the main body portion 1. At this time, the main body portion 1 cannot be further screwed into the installation cavity 201, and the volume of the water outlet cavity 10 is the smallest.

[0061] Referring to Figure 2 , the limiting portion 22 is configured as a limiting boss. Correspondingly, a limiting groove matching the shape of the limiting boss is formed at one end of the main body portion 1 provided with the water outlet port 12. When the cap body 2 is screwed relative to the main body portion 1 to a certain position, the limiting boss can abut against the limiting groove to limit the further rotation of the cap body 2 relative to the main body portion 1, so as to realize the positioning between the cap body 2 and the main body portion 1.

[0062] In some embodiments of the present application, there are multiple positioning protrusions 21. The multiple positioning protrusions 21 are arranged at intervals in the circumferential direction of the inner peripheral wall of the cap body 2, and at least one of the multiple positioning protrusions 21 can be in positioning cooperation with the sliding groove 11, so that the position of the cap body 2 relative to the main body portion 1 can be kept fixed, the volume of the water outlet cavity 10 is constant, and further the coverage range of the water column sprayed by the spraying assembly 100 is also kept constant.

[0063] It should be noted that the positioning protrusion 21 can be in positioning cooperation with positioning structures (such as positioning grooves, etc.) at different positions in the sliding groove 11 to fix the cap body 2 relative to the main body portion 1 at a corresponding position, so as to realize the adjustment of the volume of the water outlet cavity 10, and thus the adjustment of the coverage range of the water column sprayed by the spraying assembly 100 can be realized.

[0064] As Figure 8 shown, in a specific embodiment of the present application, there are two positioning protrusions 21, and the two positioning protrusions 21 are arranged at intervals on the inner peripheral wall of the cap body 2.

[0065] Among them, one of the two positioning protrusions 21 can be in positioning cooperation with one end of the sliding groove 11 and keep the cap body 2 relative to the main body portion 1 in the first position; the other of the two positioning protrusions 21 can be in positioning cooperation with the other end of the sliding groove 11 and keep the cap body 2 relative to the main body portion 1 in the second position.

[0066] It can be understood that the sliding groove 11 extends in a spiral shape, and the two positioning protrusions 21 are respectively arranged at different positions of the sliding groove 11 in the extending direction and can move synchronously relative to the sliding groove 11. When one of the positioning protrusions 21 slides to the end of the sliding groove 11, it can be in positioning cooperation with the sliding groove 11 to limit the further rotation of the positioning protrusion 21 relative to the sliding groove 11, position the cap body 2 and the main body part 1, and make the volume of the water outlet cavity 10 fixed; when the other positioning protrusion 21 slides to the other end of the sliding groove 11, it can also be in positioning cooperation with the sliding groove 11 to limit the further rotation of the positioning protrusion 21 relative to the sliding groove 11, position the cap body 2 and the main body part 1, and make the volume of the water outlet cavity 10 fixed.

[0067] It should be noted that in some embodiments, the positioning cooperation mode between the positioning protrusion 21 and the sliding groove 11 can be abutting positioning, for example: the positioning protrusion 21 abuts against one end of the sliding groove 11 in the extending direction; in other embodiments, the positioning protrusion 21 can be in positioning cooperation with the positioning groove in the sliding groove 11, that is to say, a further recessed positioning groove is provided in the sliding groove 11, and when the positioning protrusion 21 slides to the positioning groove, it can be in positioning cooperation with the positioning groove. Among them, the cooperation mode between the positioning protrusion 21 and the sliding groove 11 is not limited to this, and can also be designed according to the assembly and positioning requirements of the cap body 2 and the main body part 1.

[0068] As Figure 1 shown, in some embodiments of the present application, the sub-waterways 102 are in multiple segments, and the multiple segments of sub-waterways 102 are connected in parallel between the water outlet cavity 10 and the main waterway 101.

[0069] Among them, the structures of the multiple segments of sub-waterways 102 are the same and are all arranged around the first axis X to respectively convey water flows to one side of the water outlet cavity 10 through the multiple sub-waterways 102, and each diversion path conveys a water flow inclined relative to the first axis X to the water outlet cavity 10. Since the extending modes of the multiple segments of sub-waterways 102 are the same, multiple water flows shooting towards the water outlet cavity 10 can converge in the water outlet cavity 10 and form a vortex, which helps to improve the flow effect of the water flow in the water outlet cavity 10.

[0070] Combined Figure 5 and Figure 7 shown, in some embodiments of the present application, the cross-sectional area of the main waterway 101 at the end connected to the sub-waterway 102 is S1, the connection area between the sub-waterway 102 and the main waterway 101 is S2, the number of sub-waterways 102 is N, and the relational expression is satisfied: S1 > N × S2.

[0071] It can be understood that when the number of sub-waterways 102 is multiple, N × S2 is the total connection area between the multiple sub-waterways 102 and one side of the main waterway 101.

[0072] Among them, the cross-sectional area of the main waterway 101 at one end connected to the branch waterway 102 is larger than the area of the port where the branch waterway 102 is connected to the main waterway 101, so that the water pressure at the main waterway 101 can fully act on the branch waterway 102, thereby ensuring the water supply effect from the main waterway 101 to the branch waterway 102 side.

[0073] Referring to Figure 2 、 Figure 3 and Figure 7 , in some embodiments of the present application, in the water supply direction of the main waterway 101 to the branch waterway 102, the size of the flow cross-section of the main waterway 101 gradually decreases to ensure the water supply effect from the main waterway 101 to the branch waterway 102 side.

[0074] In some embodiments of the present application, the opening cross-section of the water outlet hole 23 gradually increases from the end connected to the water outlet cavity 10 to the side away from the water outlet cavity 10, so that the water outlet hole 23 is configured to be gradually expanding toward the water outlet side, facilitating the water column to be thrown out tangentially under the action of centrifugal force to form a water column that spreads out in all directions, thereby increasing the coverage area of the water column.

[0075] Referring to Figure 2 and Figure 3 , the water outlet hole 23 includes an equal-aperture section 231 and a variable-aperture section 232. The equal-aperture section 231 is connected between the variable-aperture section 232 and the water outlet cavity 10, and the variable-aperture section 232 is configured to be gradually expanding from the end connected to the equal-aperture section 231 to the water outlet side, so as to improve the diffusion effect of the water column.

[0076] According to the cleaning device of the embodiments of the present application, the cleaning device includes the above-mentioned spraying assembly 100 to spray a water column on the article to be cleaned through the spraying assembly 100, and the water column sprayed by the spraying assembly 100 has a large coverage area and has a good cleaning effect on articles to be cleaned such as deep-mouth cups.

[0077] At the same time, the water outlet coverage area of the spraying assembly 100 in the present application is adjustable. The gear of the spraying assembly 100 can be adjusted by rotating the cap body 2, and the scattering effect of the spraying assembly 100 can be adjusted by adjusting the size of the water outlet cavity 10, so that the spraying assembly 100 has multiple water outlet modes and improves the versatility of the spraying assembly 100.

[0078] As Figure 9 shown, in some embodiments of the present application, a water supply pipeline 200 is further provided in the cleaning device. The water supply pipeline 200 is connected to the main body portion 1 and is used for supplying water to the water supply flow path.

[0079] Among them, the spraying assembly 100 can be connected to the water supply source of the cleaning device through a water supply component.
