Description

Technical Field

[0001] This invention relates to the field of flush toilet technology, and in particular to a flushing guide, flushing assembly and urinal. Background Technology

[0002] A urinal is a sanitary fixture specifically designed for men, primarily used for collecting and discharging urine. It is widely used in public restrooms and home bathrooms. Its core function is to address the hygiene issues of male urination. Compared to a toilet seat, it is more in line with male physiological habits and features water conservation and easy cleaning. Existing urinals include an opening with a horizontal flow-receiving area for collecting urine horizontally and a vertical flow-receiving area for collecting urine vertically. However, the outer wall of the urinal inevitably becomes soiled with urine. To achieve automatic cleaning of the urinal's outer wall, existing technologies propose designing the urinal with a rotating structure. For example, Chinese Patent Publication No. CN215888492U discloses a water-saving self-cleaning urinal and urinal system. When not in use, the urinal is rotated into the inner cavity for cleaning, using a nozzle to spray a solid cone of flushing water to clean the urinal, thereby reducing the environmental impact of the cleaning process.

[0003] However, in the process of realizing this invention, the applicant discovered that, due to the limitations of the urinal's own structure, a large amount of cleaning water is required when the outer wall of the urinal needs to be thoroughly rinsed, resulting in a waste of water resources. Summary of the Invention

[0004] This invention discloses a flushing guide, a flushing assembly, and a urinal to solve the technical problem of water waste when flushing the outer wall of a urinal in related technologies.

[0005] To solve the above problems, the present invention adopts the following technical solution: The first aspect of the present invention discloses a flushing guide for use in a urinal, comprising a plate, the upper edge of which is configured to cooperate with the urinal body to form a confluence port for flushing fluid to be introduced, the lower edge of which corresponds to a portion of the urinal's opening edge; along the direction of gravity, the projection of the urinal's outer wall surface is located inside the projection of the lower edge, and there is a preset gap between the projection of the lower edge and the projection of the urinal's outer wall surface, and the projection of the upper edge is located outside the projection of the lower edge.

[0006] Furthermore, multiple raised strips are provided on the inner side of the plate along the direction of gravity.

[0007] Furthermore, the protrusion is at least located at the bottom of the plate. And / or, the cross-section of the protrusion is arc-shaped; And / or, the convex strip smoothly transitions to the inner sidewall of the plate.

[0008] Furthermore, the inner sidewall of the plate is smoothly transitioned from the upper edge to the lower edge; And / or, the lower edge corresponds to part or all of the edge of the urinal's lateral flow-facing area; And / or, the upper edge includes an arc-shaped segment for engaging with the nozzle to achieve uniform collection of the flushing fluid by the plate.

[0009] Furthermore, the plate body includes a main body area and support arm areas located on both sides of the main body area, with the side edges of the support arm areas corresponding to the pool opening edges of the vertical flow-facing area.

[0010] Furthermore, a mounting part is provided on the support arm area, which is used to fix the plate body in place; And / or, the arm area and the main body area transition smoothly; And / or, the upper edge and lower edge smoothly transition with the side edge of the support arm area, respectively.

[0011] A second aspect of the present invention discloses a flushing assembly, including a nozzle and the aforementioned flushing guide, wherein the nozzle is disposed above the flushing guide and is used to generate flushing fluid toward the confluence port.

[0012] A third aspect of the present invention discloses a urinal, comprising a urinal and the aforementioned flushing assembly, wherein the urinal has a rotational stroke about the direction of gravity, the rotational stroke including a first position and a second position, wherein in the first position the flushing guide corresponds to the opening of the urinal; and in the second position the flushing guide corresponds to the back of the urinal.

[0013] Furthermore, the urinal also includes a cleaning chamber, and the flushing guide and nozzle are disposed inside the cleaning chamber. In the first position, the front of the urinal is located inside the cleaning chamber, and in the second position, the front of the urinal is located outside the cleaning chamber.

[0014] Furthermore, along the direction of gravity, the projection of the outer wall of the urinal corresponding to the urinal opening is an arc on the first circumference, and the projection of the lower edge is an arc on the second circumference. The first and second circumferences are concentric, and the rotation axis of the urinal coincides with the axis of the first circumference.

[0015] The technical solution adopted in this invention can achieve the following beneficial effects: This invention utilizes a flushing guide to collect the flushing fluid generated by the nozzle outside the urinal's outer wall. Based on the design of the plate with the upper edge on the outside and the lower edge on the inside, the collected flushing fluid is simultaneously guided and converged into a stream. Guided by the bottom of the plate, the stream flows towards the outer wall of the urinal, thereby increasing the amount of flushing fluid acting on the outer wall. Simultaneously, the converged flushing fluid can continuously act downwards along the outer wall, flushing the outer wall from top to bottom. This not only effectively improves the utilization rate of flushing water resources but also reduces the amount of flushing water used, shortens the flushing time of the urinal, and improves the response rate of the rotating urinal.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0021] In related technologies, since the interior of a urinal is a necessary cleaning area, and considering factors such as the rational use of space, efforts are made to reduce the horizontal encroachment of the urinal on the surrounding space, such as... Figure 1 As shown, a flushing nozzle 20 needs to be installed above the urinal so that the flushing fluid generated by the flushing nozzle 20 (corresponding to...) Figure 1 The flushing fluid (covered by the central angle a) mainly flows into the interior of the urinal 30 for flushing, so very little flushing fluid flows to the outer wall of the urinal 30 (the front of the urinal 30). Simultaneously, there is an angle between the outer wall of the urinal 30 and the nozzle 20, resulting in a very small effective central angle between the outer wall of the urinal 30 and the corresponding flushing nozzle 20. Figure 1 For the area covered by the middle corner (b), the flushing time needs to be extended to completely clean the outer wall of the urinal 30. During this process, not only may the flushing water flowing into the urinal 30 be wasted, but the flushing fluid outside the outer wall of the urinal 30 is almost entirely unused (corresponding to...). Figure 1 The area covered by the central corner (c) further exacerbated the problem of water waste.

[0022] To address this, this application provides a flushing guide, a flushing assembly, and a urinal. The flushing guide collects flushing fluid generated by the nozzle outside the outer wall of the urinal 30. Based on the design of the plate with the upper edge on the outside and the lower edge on the inside, the collected flushing fluid is simultaneously guided and converged into a stream. Guided by the bottom of the plate, the stream flows towards the outer wall of the urinal 30, thereby increasing the amount of flushing fluid acting on the outer wall of the urinal 30. At the same time, the converged flushing fluid can continue to act downward along the outer wall of the urinal 30, flushing the outer wall from top to bottom. This not only effectively improves the utilization rate of flushing water resources but also reduces the amount of flushing water used, shortens the flushing time of the urinal 30, and improves the response rate of the rotating urinal.

[0023] The following is in conjunction with the appendix Figures 1 to 12 The present application provides a detailed description of the headphones and electronic devices provided through specific embodiments and application scenarios.

[0024] This embodiment provides a flushing guide 10 applied to a urinal 30. The urinal 30 can be an existing rotating urinal 30 or a fixed urinal 30; no specific limitation is made here. To facilitate the use of the urinal 30, when the urinal 30 is a rotating urinal 30, the flushing guide 10 can be a fixed structure; when the urinal 30 is a fixed urinal 30, the flushing guide 10 can be a movable structure, allowing the opening of the urinal 30 to be exposed for use. Figures 2-5 As shown, the flushing guide 10 includes a plate 100. To improve space utilization, the structure of the plate 100 corresponds to and matches the structure of the urinal opening 310, thereby making reasonable use of the space at the urinal opening 310. Figure 8As shown, the upper edge 110 of the plate 100 is used to cooperate with the urinal 30 to form a confluence port 150. The confluence port 150 is used to introduce flushing fluid, which is generally generated by the nozzle 20 to achieve a conical flushing fluid. The flushing fluid enters between the flushing guide 10 and the urinal 30 through the confluence port 150, mainly towards the opening 310 of the urinal 30 for flushing. A portion of the flushing fluid flows in a direction corresponding to the plate 100. The plate 100 is used to collect and guide this portion of the flushing fluid, directing the collected flushing fluid to the outer wall surface 320 of the urinal 30. In this process, the dispersed flushing fluid is gathered into a stream and concentrated towards the outer wall surface 320 of the urinal 30, enhancing the impact effect of the flushing fluid on the outer wall surface 320 of the urinal 30. The lower edge 120 of the plate 100 corresponds to the edge of part of the opening 310 of the urinal 30, so that the flushing fluid can flush the outer wall surface 320 of the urinal 30 from the edge of the opening 310. The projection of the outer wall surface 320 of the urinal 30 along the direction of gravity is located inside the projection of the lower edge 120, and there is a preset gap between the projection of the lower edge 120 and the projection of the outer wall surface 320 of the urinal 30. The preset gap can allow the flushing fluid left from the plate 100 to pass through and guide it to the edge of the opening 310 of the urinal 30. The projection of the upper edge 110 is located outside the projection of the lower edge 120, so that the bottom of the plate 100 is inclined toward the urinal 30. During the application, the flushing fluid on the plate 100 can be guided to flow toward the urinal.

[0025] In practical applications, the flushing guide can be applied to existing rotating urinals. When flushing of the urinal 30 is required, the nozzle 20 generates a solid cone-shaped flushing fluid above the flushing guide 10. The flushing fluid flows through the confluence port 150 to the front of the urinal 30 and the inside of the flushing guide 10. The flushing fluid flowing to the urinal 30 mainly passes through the bowl opening 310 of the urinal 30 to flush the inside of the urinal 30. The flushing fluid flowing to the flushing guide 10 interacts with the plate... The flushing fluid is collected by the flushing guide 10 on the inner sidewall of the urinal 100 and flows downward along the inner sidewall of the urinal 100 under the action of gravity. During the downward flow, the urinal 100 contacts and collects flushing fluid at different central angles. The newly collected flushing fluid merges with the flushing fluid flowing through it, and gradually converges into a stream during the flow guidance process of the urinal 100. This allows the originally dispersed flushing fluid to converge into a concentrated flushing fluid, which flows synchronously towards the edge of the urinal opening 310 (the edge of the urinal opening 310 is easily...). The urine-contaminated area is flushed from top to bottom along the edge of the urinal opening 310 onto the outer wall 320 of the urinal 30. This allows flushing fluid that was originally outside the outer wall 320 of the urinal 30 to be utilized for flushing the outer wall 320 as well. Simultaneously, due to the increased flow rate, the final flow rate of the flushing fluid acting on the outer wall 30 increases, enhancing the impact effect of the flushing fluid on the outer wall 320 of the urinal 30. This not only improves the flushing effect on the outer wall of the urinal 30... The flushing effect is improved, and the problem of blind spots in the flushing of the dispersed flushing fluid acting on the outer wall of the urinal 30 is reduced. In addition, the flushing fluid will also flow from top to bottom along the outer wall 320 of the urinal 30 to flush the outer wall 320. All the collected flushing fluid will flow from top to bottom to flush the outer wall 320, which not only effectively improves the utilization rate of flushing water resources, but also reduces the amount of flushing water used, shortens the flushing time of the urinal 30, and improves the response rate of the rotating urinal.

[0026] Furthermore, based on the above structural design, even if the nozzle 20 is designed in the square shape of the urinal 30, that is, the projection of the nozzle 20 in the direction of gravity is located on the inner side of the outer wall of the urinal 30 (correspondingly, the flushing fluid sprayed by the nozzle 20 cannot directly act on the outer wall 320 of the urinal 30), the flushing fluid that was originally sprayed outside the outer wall 320 of the urinal 30 can be collected and guided to flush the outer wall of the urinal 30 through the cooperation of the flushing guide 10, further reducing the occupation of the horizontal space by the urinal 30 spray assembly and improving the space utilization rate.

[0027] In some embodiments, to ensure that the flushing fluid collected by the flushing guide 10 is uniformly applied to the outer wall 320 of the urinal 30, multiple protrusions 130 can be provided along the direction of gravity on the inner side of the plate 100. The multiple protrusions 130 separate the flushing fluid collected on the plate 100, reducing the inertial influence of the flushing fluid before contacting the plate 100, and making the flow rate of the flushing fluid on the plate 100 after separation similar. Finally, multiple streams of flushing fluid are formed on the plate 100 and flush different areas of the outer wall 320 of the urinal 30 respectively, thereby achieving uniform flushing of the outer wall 320 of the urinal 30, reducing the flushing blind zone of the outer wall 320 of the urinal 30, and improving the utilization rate of flushing water resources. At the same time, the design of the protrusions 130 can also enhance the structural strength of the flushing guide 10, improve the physical properties of the flushing guide 10, reduce its damage risk, and increase its service life.

[0028] In some embodiments, in order to effectively guide the flushing fluid that is separated and collected on the plate 100, the protrusion 130 may be provided at least at the bottom of the plate 100; specifically, the protrusion 130 may extend from the middle of the plate 100 to the bottom of the plate 100, or the protrusion 130 may extend from the top of the plate 100 to the bottom of the plate 100. In this embodiment, it is preferred that the protrusion 130 extend from the top of the plate 100 to the bottom of the plate 100.

[0029] In some embodiments, to improve the collection, guiding, and aggregation effect of the flushing fluid on the plate 100, the cross-section of the protrusion 130 can be set to be arc-shaped; specifically, the protrusion 130 can also be set to smoothly transition with the inner sidewall of the plate 100 to avoid the formation of dead corners between the protrusion 130 and the inner sidewall of the plate 100 to trap dirt.

[0030] In some embodiments, a hydrophobic layer may be provided on the inner sidewall of the plate 100, or the plate 100 may be made of a hydrophobic material to improve the collection, diversion and aggregation effect of the plate 100 on the flushing fluid.

[0031] In some embodiments, to achieve orderly flow of flushing fluid on the plate 100, the inner sidewall of the plate 100 may be configured to smoothly transition from the upper edge to the lower edge.

[0032] In actual use, the outer wall surface 320 of the urinal 30 corresponding to the transverse flow-facing area is more easily contaminated by urine. To meet actual cleaning needs, the lower edge 120 can be set to correspond to part or all of the edge of the urinal opening 310 in the transverse flow-facing area. Based on the above structure, the flushing fluid collected in the plate 100 can be concentrated to flush the outer wall surface 320 of the urinal 30 corresponding to the transverse flow-facing area, further improving water resource utilization.

[0033] In some embodiments, to achieve uniform flushing of the urinal 30 outer wall 320 by flushing fluid, the upper edge 110 may include an arc-shaped segment 111, such as... Figure 5 As shown, the arc-shaped segment 111 is used in conjunction with the nozzle 20 to achieve uniform collection of flushing fluid by the plate 100. Specifically, the arc-shaped segment 111 is adapted to the boundary of the solid cone flushing fluid generated by the nozzle 20 on the same horizontal plane, that is, the arc-shaped segment 111 is close to the boundary of the flushing fluid on the same plane. This can ensure that the amount of flushing fluid collected by the plate 100 within the arc-shaped segment 111 is similar, and reduce the lateral displacement on the plate 100 caused by the inertia of the flushing fluid before contacting the plate 100. In conjunction with the protrusion 130, uniform collection of flushing fluid is achieved, and then subsequent guidance and convergence are carried out. The flow rate of flushing fluid flowing to different areas of the outer wall 320 of the urinal 30 is similar, thereby achieving uniform flushing of the outer wall 320 of the urinal 30 by the flushing fluid and improving water resource utilization.

[0034] In some embodiments, to achieve cleaning of the outer wall 320 of the urinal 30 corresponding to the vertical flow-facing area, the plate 100 may be provided with a main body area and support arm areas 140 on both sides of the main body area. The side edge of the support arm area 140 corresponds to the edge of the pool opening 310 of the vertical flow-facing area. The support arm area 140 collects flushing fluid and guides and converges it to the edge of the pool opening 310 of the vertical flow-facing area to flush the outer wall 320 of the urinal 30 corresponding to the vertical flow-facing area, thereby reducing the cleaning blind spots of the outer wall 320 of the urinal 30.

[0035] Specifically, an mounting part 142 can be provided on the support arm area 140. The mounting part 142 is used to fix the plate 100. For a rotating urinal, the mounting part 142 can be fixedly connected to the inner wall of the washing chamber to fix the flushing guide 10. Preferably, part of the arc-shaped segment 111 is located in the support arm area 140, and the other part is located in the main body area.

[0036] Specifically, the support arm area 140 and the main body area can be set to have a smooth transition, so as to improve the collection, guidance and aggregation effect of the plate 100 on the flushing fluid.

[0037] Specifically, the upper edge 110 and lower edge 120 can be set to smoothly transition with the side edge 141 of the support arm area 140, so as to improve the collection, guiding and converging effect of the plate 100 on the flushing fluid.

[0038] This embodiment provides a rinsing assembly, such as... Figures 8-10As shown, the device includes a nozzle 20 and a flushing guide 10 as described in the above embodiment. The nozzle 20 is positioned above the flushing guide 10 and is used to generate flushing fluid toward the manifold 150. Specifically, the nozzle 20 generates flushing fluid in a solid cone shape. It should be noted that the nozzle 20 is prior art and can specifically be a solid cone nozzle.

[0039] In some implementations, to improve the utilization rate of flushing fluid, the nozzle 20 can be positioned above the arc segment 111, with the spray direction of the nozzle 20 facing the opening 310 of the urinal 30, and the angle between the spray direction of the nozzle 20 and the direction of gravity is 45°~75°, preferably 55°~65°.

[0040] This embodiment provides a urinal, such as Figures 6-12 As shown, the urinal includes a urinal 30 and the flushing assembly in the above embodiment. The urinal 30 has a rotational stroke about the direction of gravity. The rotational stroke includes a first position and a second position. In the first position, the flushing guide 10 corresponds to the opening 310 of the urinal 30. In the second position, the flushing guide 10 corresponds to the back 330 of the urinal 30. When it is necessary to flush the front of the urinal 30, rotate the urinal 30 to the first position. At this time, activate the nozzle 20 to spray a solid cone of flushing fluid. Most of the flushing fluid enters the opening 310 of the urinal 30 to flush the inside of the urinal 30. A small portion flows to the flushing guide 10, which collects, guides, and converges the dispersed flushing fluid to form a relatively larger flow of flushing fluid that flushes the outer wall 320 of the urinal 30 from top to bottom along the edge of the opening 310. This allows the flushing fluid that was originally outside the outer wall 320 of the urinal 30 to be used to flush the outer wall 320 of the urinal 30. This not only effectively improves the utilization rate of flushing water resources but also reduces the amount of flushing water used, shortens the flushing time of the urinal, and improves the response rate of the rotating urinal.

[0041] When it is necessary to rinse the back of the urinal 30, the urinal 30 is rotated to the second position, and the rinsing fluid generated by the nozzle 20 acts on the back of the urinal 30 330, which can rinse the back of the urinal 30 330.

[0042] In some embodiments, the urinal further includes a cleaning chamber, which can be provided by the outer shell 40 of the urinal 30, by the mounting wall of the urinal 30, or by the outer shell 40 and the mounting wall together. The cleaning chamber reduces the amount of flushing fluid entering the external environment during the flushing process, thus avoiding pollution of the environment surrounding the urinal. The flushing guide 10 and the nozzle 20 are disposed within the cleaning chamber. In the first position, the front of the urinal 30 is located inside the cleaning chamber; in the second position, the front of the urinal 30 is located outside the cleaning chamber, allowing men to urinate.

[0043] In some embodiments, to reduce interference during urinal operation and improve space utilization, the projection of the outer wall of the urinal 30 corresponding to the opening 310 of the urinal 30 can be set as an arc on a first circumference along the direction of gravity, and the projection of the lower edge 120 can be an arc on a second circumference. The first and second circumferences are concentric, and the rotation axis of the urinal 30 coincides with the axis of the first circumference. Based on the above structure, the volume of the urinal can be reduced, the space utilization of the urinal can be improved, and the front outer wall 320 of the urinal 30 can be efficiently flushed in conjunction with the flushing guide 10 and the nozzle 20. This not only effectively improves the utilization rate of flushing water resources, but also reduces the amount of flushing water used, shortens the flushing time of the urinal, and improves the response rate of the rotating urinal.
