Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in this application.

As shown in Figures 1-2, the embodiment of the present application provides a water spray structure 100, the water spray structure 100 includes a housing 10, the housing 10 has an inner cavity, and is provided with a water inlet 11 and a flow guide cavity 12 , the water outlet chamber part 13, the water outlet part 14 and a plurality of water outlet holes 15, which can realize uniform water spraying. Here, the X direction, the Y direction, and the Z direction can be defined as follows. The X direction is a horizontal direction extending from the rear side of the housing 10 to its front side, the front side and the rear side of the housing 10 are defined as the direction when the user uses the cleaning device, and the Y direction is the extending direction of the inner cavity of the housing 10, The Z direction is the vertical extension direction of the casing 10 .

The diversion chamber part 12 communicates with the water inlet hole 11 , and the liquid is introduced into the diversion chamber part 12 through the water inlet hole 11 . The flow guide cavity 12 is configured to make the liquid flowing into the flow guide cavity 12 flow along the extension direction of the flow guide cavity 12 , so that the liquid can evenly spread to the entire area of the flow guide cavity 12 along the extension direction. Here, the liquid may be configured according to actual needs, and may be of a type such as clean water or cleaning liquid, which is not limited in this embodiment of the present application.

The water outlet cavity 13 is at least partly adjacent to the diversion cavity 12 along the first direction, the first direction is perpendicular to the extension direction of the diversion cavity, and the diversion cavity 12 is adjacent to the water inlet hole 11 , the water outlet cavity portion 13 is adjacent to the water outlet hole 15 . The extending direction of the flow guide chamber part 12 and the extending direction of the water outlet chamber part 13 are the same as the extending direction of the inner chamber of the housing 10 . As shown in FIGS. 1 and 3 , in some embodiments, all the cavity sections in the water outlet cavity 13 are arranged adjacent to the flow guide cavity 12 in sequence along the first direction, and the first direction and the flow guide The extending direction of the cavity is vertical. As shown in Figures 5 to 8, in some other embodiments, the water outlet cavity 13 is only arranged adjacent to the flow guide cavity 12 in a certain cavity segment along the first direction, and the first direction is adjacent to the flow guide cavity 12. The direction of extension is vertical, and no diversion cavity portion 12 is provided on the remaining cavity segments. In some other embodiments, some cavity sections in the water outlet cavity section 13 that are not directly connected to the guide cavity section 12 are arranged adjacently in sequence along the first direction, while the flow guide cavity section 12 is not provided on the remaining cavity sections.

As shown in Fig. 2 and Fig. 4, the water outlet part 14 is formed in the adjacent area of the flow guide cavity part 12 and the water outlet cavity part 13, the water outlet part 14 communicates with the water outlet cavity part 13 and the flow guide cavity part 12, and the water outlet part 14 The length direction of the guide cavity part 12 is parallel to the extending direction. In this way, after being diverted by the diversion cavity part 12, the liquid distributed in the direction of the diversion cavity part 12 along its extending direction can enter the water outlet cavity part 13 synchronously through the water outlet part 14, and be immediately distributed along the direction of the water outlet cavity part 13. At least part of the area in its extending direction, and then quickly spread to each area of the water outlet chamber portion 13 along its extending direction.

The aforementioned plurality of water outlet holes 15 are formed on the side of the water outlet chamber portion 13 away from the guide chamber portion 12 , and are sequentially arranged at intervals along the extending direction of the water outlet chamber portion 13 . In this way, after the liquid enters the water outlet cavity 13 synchronously through the water outlet portion 14 , it can flow to each water outlet hole 15 along the extending direction of the water outlet cavity 13 to spray water evenly.

In the related art, the water spray structure of the cleaning equipment is composed of a water inlet hole end, a fluid cavity and a plurality of water outlet hole ends. The fluid cavity generally extends along the horizontal direction, and the ends of these water outlet holes are sequentially arranged along the extending direction of the fluid cavity, forming a horizontal array distributed from near to far from the ends of the water inlet holes. Correspondingly, the distances between the ends of the different water outlet holes and the ends of the water inlet holes are different, with the area in the fluid chamber that is closer to the end of the water inlet hole as the proximal end, and the area in the fluid chamber that is farther away from the end of the water inlet hole The region of is the remote end. When spraying water, the liquid entering the fluid chamber from the water inlet end needs to pass through each water outlet hole end from near to far along the extension direction of the fluid chamber, and sprays sequentially at each water outlet hole end. Part of the liquid will be ejected from the end of each outlet hole, resulting in the loss of liquid mass and pressure in the fluid cavity, and the pressure of the liquid will continuously drop from near to far. In this way, at the near end of the water outlet hole, the liquid pressure is relatively large and easy to overcome the external air pressure, so that the water outlet end is easy to spray water; while at the far end of the water outlet hole, the liquid pressure is small and difficult to overcome the external air pressure. Pressure makes it difficult to spray water at the water outlet end; when the liquid pressure drops rapidly or the input flow at the water inlet end is small, it may even be unable to overcome the gas pressure in the fluid chamber to reach the water outlet end at the far end. As a result, there will be a problem of uneven water spraying at the water outlet ends with different distances from the water inlet end, so that the water spray structure shows that the near end sprays water but the far end does not spray water, or the near end sprays a large amount of water and the far end does not spray water. The small amount of water sprayed at the end causes some areas in the cleaned area to be wet while other areas are dry, or some areas have more water while other areas have less water, resulting in a decline in the cleaning degree and cleaning efficiency of cleaning equipment in related technologies , and there is a risk of damaging the area being cleaned, the brush or the rag by scrubbing in dry conditions. This problem is particularly noticeable when the input flow at the water inlet end is small, that is, when the flow rate is low, or when the number of water outlet holes reaches more than twenty or thirty.

Compared with the related technology, the water spray structure 100 provided by the embodiment of the present application is provided with a flow guide cavity 12 and a water outlet cavity 13 in the housing 10, and forms a communication in the adjacent area of the water outlet cavity 13 and the flow guide cavity 12 The water inlet portion 14 of the two, the length direction of the water inlet portion 14 is configured to be parallel to the extending direction of the diversion cavity portion 12 . When the liquid enters the diversion cavity from the water inlet hole 11, the diversion cavity part 12 can make the liquid flow along the extension direction of the diversion cavity part 12 and evenly spread to the entire area of the diversion cavity part 12 along its extension direction, and then Every place along the extending direction of the diversion chamber part 12 enters the water outlet chamber part 13 through the water outlet part 14 respectively.

In this way, when the aforesaid plurality of water outlet holes 15 are all located in the cavity section directly connected to the water outlet portion 14 in the water outlet cavity portion 13, the liquid entering the water outlet cavity portion 13 through the water outlet portion 14 can directly reach each water outlet hole 15 for further processing. Direct injection, the liquid does not need to pass through each water outlet 15 from near to far without pressure loss, and the liquid pressure at each water outlet 15 is consistent or basically the same, so that each water outlet 15 sprays water evenly, ensuring that the area to be cleaned can be uniform Receiving water can increase the cleanliness and cleaning efficiency of cleaning equipment. Part of the water outlet hole 15 is located in the water outlet cavity portion 13 and the cavity segment directly connected to the water outlet portion 14 (hereinafter referred to as the proximal cavity segment), while the remaining water outlet holes 15 are located in the remaining cavity segments in the water outlet cavity portion 13 (hereinafter referred to as the distal end. When the liquid enters the water outlet cavity 13 through the water outlet 14, part of the liquid can directly reach the water outlet holes 15 located in the proximal cavity section for direct spraying, and this part of the liquid does not need to pass through the near-end cavity section Each water outlet hole 15 of the end chamber section does not have pressure loss, and the liquid pressure at each water outlet hole 15 of the near-end chamber section is consistent or basically the same, and the water spray is relatively uniform; The area of the section enters the far-end chamber section, passes through each water outlet hole 15 located in the far-end chamber section in turn along the extension direction of the water outlet chamber part 13, and sprays through these water outlet holes 15 respectively, which can reduce the amount of water passing through from near to far. The number of water outlet holes 15 and the resulting liquid pressure loss increase the water spray uniformity of each water outlet hole 15 located in the far-end chamber section, reduce or eliminate the near-end water spray and the far-end no water spray, or the near-end water spray Risk of inhomogeneity with larger volumes and smaller volumes at the far end. When the input flow rate of the water inlet hole 11 is small, that is, the flow rate is low, each water outlet hole 15 can still spray water evenly. To sum up, the water spraying structure 100 provided by the embodiment of the present application can make the water spraying from each water outlet hole 15 relatively uniform. When the water spray structure 100 is applied to cleaning equipment, it can keep the area to be cleaned uniform and fully wet, so that the roller brush or rag can thoroughly scrub the area to be cleaned, increasing the cleanliness and cleanliness of the cleaning equipment. efficiency.

Laminar flow is formed. In this way, the liquid injected from the water inlet 11 can first be adjusted to an orderly laminar flow state in the front chamber part 121, and then flow into the guide chamber part 12 in an orderly manner along the preset direction and along the direction of the guide chamber. The extension direction of the portion 12 flows sequentially, so as to avoid disordered turbulent flow disturbance after the liquid is ejected from the water inlet hole 11 . Here, the flow cross-section of the front chamber part 121 may be configured to be larger than the flow cross-section of the flow guide chamber part 12, and the connection area between the two forms a slope structure.

Here, a plurality of water inlet holes 11 can be set as before; and a plurality of flow guide cavity parts 12 are successively arranged at intervals along the extending direction of the water outlet cavity part 13, so that each flow guide cavity part 12 is connected with one of the water outlet cavity parts 13 respectively. The cavity segments are arranged adjacently in sequence along the first direction. Meanwhile, each diversion chamber part 12 communicates with at least one water inlet hole 11 respectively, and the water inlet holes 11 connected by different diversion chamber parts 12 may be different. In this way, a plurality of water inlet holes 11 can be corresponded to by a plurality of diversion cavity parts 12, and different diversion cavity parts 12 are used to make the liquid imported by each water inlet hole 11 fully divert, so that each water outlet hole 15 sprays water for comparison. uniform. Exemplarily, the number of diversion chambers 12 and water inlet holes 11 are equal and communicated in one-to-one correspondence, so that the liquid input by each water inlet hole 11 can enter different diversion chambers 12, and the diversion effect is more sufficient And the distribution is relatively uniform, increasing the water spray uniformity of each water outlet hole 15.

As shown in FIGS. 7-8 , for example, the part of the water outlet cavity 13 between two adjacent guide cavity parts 12 may form a first rear sub-cavity 132 , and the first rear sub-cavity 132 It gradually shrinks from the opposite ends along its extension direction to the middle. The first rear sub-chamber 132 is not adjacent to any one of the guide chambers 12 in the first direction, but the opposite ends of the first rear sub-chamber 132 along its extending direction are respectively close to different guide chambers part 12, and the middle part located between the two opposite ends is relatively far away from the diversion chamber part 12; from any one of the two opposite ends to the middle part, the flow cross-sectional area of the first rear sub-cavity part 132 gradually decreases , forming a contracted lumen structure. In this way, in the process of the liquid flowing from the end of the first rear sub-cavity 132 to the middle, the liquid passes through the water outlet holes 15 on the first rear sub-cavity 132 to be sprayed, so that the water in the first rear sub-cavity 132 The quality of the liquid is continuously lost; since the flow cross-sectional area of the first rear sub-cavity 132 gradually decreases, the liquid can be continuously concentrated while the mass is reduced to increase the pressure of the liquid, thereby compensating for the pressure loss caused by the loss of the liquid mass and making the liquid pressure The flow process is generally kept stable without fluctuations or obvious fluctuations. Correspondingly, the liquid pressure at each water outlet hole 15 in the first rear sub-cavity 132 is kept consistent or substantially consistent, and the water spray is relatively uniform.

The gradual contraction structure of the first rear sub-cavity 132 can be realized by any side or multiple sides of the first rear sub-cavity 132 having a gradual design, which is not limited in this embodiment of the present application. Exemplarily, the first rear sub-chamber 132 may have a first side and a second side oppositely disposed along the first direction, the water outlet hole 15 is disposed on the first side, and the second side extends from opposite ends along its extending direction to The middle gradually shrinks. In this way, the shrinkage and gradual change structure of the first rear sub-chamber 132 can be realized mainly through the second side, and the other sides can be kept flat. On the one hand, the water spray structure 100 can be easily arranged on the cleaning equipment and save space. On the one hand, it can make the water outlet holes 15 arranged on the first side more evenly close to the area to be cleaned, increasing the cleaning effect. Here, the second side can be formed by extending along an arc, so that the second side has an arc-shaped wall structure, and the first rear sub-cavity 132 has a circular-arc contraction cavity structure; The first rear sub-cavity 132 has a straight-line contraction cavity structure at both ends, and forms a rounded transition cavity structure at the transition in the middle.

Here, the second sub-rear cavity part is not adjacent to any one of the flow guide cavity parts 12 in the first direction, and the second sub-rear cavity part 133 is only close to one flow guide cavity part 12 at one end. One end of the second rear sub-chamber 133 is connected to the front sub-chamber 131 along its extending direction, and the other end is relatively far away from the front sub-chamber 131 to form an end of the water outlet chamber 13 . From the end of the second rear sub-cavity 133 close to the front sub-cavity 131 to the end away from the front sub-cavity 131 , the flow cross-sectional area of the second rear sub-cavity 133 gradually decreases, forming a contracted cavity structure. In this way, after the liquid enters the second rear sub-chamber 133 from the front sub-cavity 131, the liquid flows through the outlet holes 15 on the second rear sub-cavity 133 in sequence along the extension direction of the second sub-rear chamber 133 to Spraying, so that the liquid quality in the second rear sub-cavity 133 is continuously lost; because the flow cross-sectional area of the second rear sub-cavity 133 gradually decreases, the liquid can be continuously concentrated while the mass is reduced to increase the liquid pressure, In this way, the pressure loss caused by the loss of liquid mass is compensated, so that the liquid pressure remains roughly stable during the flow process without fluctuations or obvious fluctuations. Correspondingly, the liquid pressure at each water outlet hole 15 in the second rear sub-chamber 133 remains consistent Or basically the same, and the water spray is relatively uniform.

The direction of 131 gradually shrinks. In this way, the shrinking and gradual structure of the second rear sub-chamber 133 can be realized mainly through the second side, so that the other sides can be kept flat. On the one hand, the water spray structure 100 can be easily arranged on the cleaning equipment and save space. On the one hand, the water outlet holes 15 arranged on the first side can be made to be evenly close to the area to be cleaned, increasing the cleaning effect. Here, the second side portion can be formed by extending along an arc, so that the second side portion has an arc-shaped wall surface structure, and the second rear sub-cavity portion 133 has a circular-arc shrinking cavity structure; or, the second side portion can also be formed along a straight line. The line is extended so that the second rear sub-cavity part 133 has a straight-line shrinkage cavity structure. Exemplarily, the minimum distance between the second side part and the first side part is not less than 2mm, which meets a relatively large flow requirement.

The part of the water outlet cavity 13 adjacent to the guide cavity 12 along the first direction can form the front sub-cavity 131, and the structure of the front sub-cavity 131 can be determined according to actual needs, which is not limited in the embodiment of the present application. . In some embodiments, when the ratio of the length of the front sub-chamber 131 to the length of the water outlet chamber 13 is not greater than the first threshold, the flow cross-sectional area of the front sub-chamber 131 is equal everywhere. Here, the flow section of the front sub-chamber 131 remains constant along its extending direction, which can ensure that each water outlet hole 15 sprays water evenly and has a better flow rate. The specific numerical value of the first threshold may be obtained according to practical structural tests, which is not limited in this embodiment of the present application. In some examples, the first threshold may be 1/10.

In other embodiments, when the ratio of the length of the front sub-chamber 131 to the length of the outlet chamber 13 is not less than the second threshold, the front sub-chamber 131 gradually shrinks along its extending direction. Here, the flow cross-section of the front sub-cavity portion 131 gradually decreases along its extending direction. Like this, when there may be liquid flowing along its extension direction in the front sub-chamber 131, the liquid is sprayed through the water outlet holes 15 on the front sub-chamber 131 successively, so that the liquid quality in the front sub-chamber 131 is continuously lost; The flow cross-sectional area of the front sub-cavity 131 gradually decreases, which can make the liquid continuously concentrate and increase the liquid pressure while the mass is reduced, thereby compensating for the pressure loss caused by the loss of liquid mass, and keeping the liquid pressure roughly stable during the flow process. There will be fluctuations or obvious fluctuations. Correspondingly, the liquid pressure at each water outlet hole 15 in the front subcavity 131 remains consistent or substantially consistent, and the water spray is relatively uniform. When the water outlet cavity 13 includes the first rear sub-cavity 132 and/or the second rear sub-cavity 133 connected to the front sub-cavity 131, the front sub-cavity 131 can approach the first rear sub-cavity 132 and/or Or the direction of the second rear sub-cavity portion 133 gradually shrinks.
