Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic sanitary ware, in particular to a toilet water spray assembly and a toilet. Background Art

[0002] As people's living standards continue to improve, people are no longer satisfied with simple toilet needs, but are more pursuing a hygienic, healthy and comfortable toilet experience. The upper nozzle is a more important water outlet device in smart toilets. Its water outlet effect largely affects whether people have a hygienic, healthy and comfortable toilet experience.

[0003] Traditional upper nozzles often have such a problem: the performance is affected by the structural size, the water flow diverges heavily, and a stable rectified water flow cannot be obtained, resulting in splashing when flushing the toilet. The splashing water droplets will pollute the inside and outside of the toilet and cause water waste. At the same time, due to the divergence of the water flow, its impact force is low and the coverage range is small, resulting in poor flushing effect and failure to meet the needs of users. Utility Model Content

[0004] In order to solve the problems in the above-mentioned background technology, the utility model provides a toilet water spray assembly and a toilet. The water spray assembly has a rectifying structure, which can improve the concentration of water flow when water flows through the water spray assembly to form a rectifying effect, thereby preventing water from splashing.

[0005] The first aspect of the utility model is to provide a toilet water spray assembly, which includes a nozzle body and a water outlet member sealed at one end of the nozzle body through a nozzle upper cover;

[0006] A first water passage, a second water passage and an installation cavity are formed in the nozzle body from top to bottom, and the diameter of the first water passage is smaller than that of the second water passage.

[0007] One end of the water outlet part extends into the installation cavity, and the other end of the water outlet part passes through the nozzle cover and extends out of the nozzle body; the water outlet part includes a rectifying column located in the middle and a plurality of water holes separated from each other formed around the rectifying column. A third water passage is formed in the water outlet part below the water hole, and the second water passage is connected to the third water passage through the water hole.

[0008] Furthermore, the inner peripheral wall of the installation cavity is formed as a first curved surface, and the outer peripheral wall of the water outlet component located in the installation cavity forms a second curved surface. The first curved surface is adapted to the second curved surface, and the water outlet component can swing and rotate along the first curved surface of the installation cavity under the impact force of water.

[0009] Furthermore, the upper end portion of the rectifying column is a conical structure, and the upper end surface of the rectifying column is the small end of the conical structure.

[0010] Furthermore, the water holes are formed by multiple partitions surrounding the rectifying column, and the partitions include annular partitions and radial partitions. The multiple annular partitions are arranged in sequence from the inside to the outside. The annular partitions divide the space between the rectifying column and the inner side of the water outlet into multiple annular spaces. Multiple radial partitions are arranged annularly at intervals in each annular space. The radial partitions divide the annular space into multiple water holes, and the water holes are arranged vertically downward.

[0011] Furthermore, a confluence groove is formed above the water hole in the water outlet member, and the upper end of the rectifying column is located in the confluence groove.

[0012] Furthermore, a rib abutting against the nozzle cover is provided on the outer wall of the nozzle body, a first external thread is provided on the outer wall of the nozzle body below the rib, and a first internal thread screwed to the first external thread is provided in the nozzle cover.

[0013] Furthermore, a second external thread is provided on the outer wall of the nozzle body above the retaining edge, and the second external thread is located on the outer wall of the second water passage. A sealing gasket and a locking nut are screwed on the second external thread in sequence. The outer wall of the first water passage is a connecting part, which is used to connect to the connecting pipe.

[0014] Furthermore, a sealing ring is provided between the nozzle upper cover and the water outlet member.

[0015] A second aspect of the present invention is to provide a toilet, comprising a toilet body and a water spray assembly installed on the toilet body.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) The water spray assembly of the present invention includes a nozzle body and a water outlet. A first water passage and a second water passage are provided in the nozzle body, and the diameter of the first water passage is smaller than that of the second water passage. The water outlet includes a rectifying column located in the middle and a plurality of water holes formed around the rectifying column and separated from each other. A third water passage is formed in the water outlet below the water holes. When flushing the toilet, when water flows from the first water passage into the second water passage, the flow rate increases and vertical flow and spiral flow are generated. Since the rectifying column is provided, the centrifugal force of most of the spiral flow disappears, making the water flow more evenly distributed in the vertical direction. After the evenly distributed water flow passes through the water hole and enters the third water passage, the flow rate becomes more even and stable, thereby ensuring that the water flow ejected outward from the water spray assembly will not splash outward.

[0018] (2) The inner peripheral wall of the installation cavity of the water spray assembly of the present application is formed into a first curved surface, and the outer peripheral wall of the water outlet is formed into a second curved surface that matches the first curved surface. When the water flow from the second water passage flows to the water outlet, an impact force is generated on the water outlet, causing the water outlet to swing and rotate along the first curved surface, allowing the water spray assembly to more freely adjust the water outlet direction, increase the flushing area, more effectively improve the flushing effect, and ensure the cleanliness of the inside of the toilet.

DETAILED DESCRIPTION

[0027] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The following is combined with Figure 1 To the attached Figure 5 And specific embodiments discuss the present invention in detail.

[0029] like Figure 1-5 As shown, the present invention provides a toilet water spray assembly, which is installed on the toilet body 8 and provides a stable water flow with a certain impact force for flushing the toilet. The water spray assembly 0 of the present application includes a nozzle body 1 and a water outlet 3 sealed at one end of the nozzle body 1 by a nozzle upper cover 2; a first water flow channel 11, a second water flow channel 12 and an installation cavity 13 are formed in the nozzle body 1 from top to bottom, which are connected in sequence; one end of the water outlet 3 extends into the installation cavity 13 and is sealed in the installation cavity 13 by the nozzle upper cover 2, and the other end of the water outlet 3 penetrates the nozzle upper cover 2 and extends out of the nozzle body 1, and the water flows through the first water flow channel 11 and the second water flow channel 12 in sequence and then flows out through the water outlet 3;

[0030] The water outlet 3 includes a rectifying column 31 in the middle and a plurality of water holes 32 formed around the rectifying column 31 and separated from each other. A third water channel 33 is formed in the water outlet 3 below the water hole 32. The diameter of the first water channel 11 is smaller than that of the second water channel 12. The second water channel 12 is connected to the third water channel 33 through the water hole 32. When flushing the toilet, the control button is pressed, and the water flows into the first water channel 11. The water entering the first water channel 11 is a vertical flow. When the water flows from the first water channel 11 into the second water channel 12, according to the Venturi principle, as the diameter becomes larger, the pressure becomes smaller and the flow rate becomes larger, causing the water flow through the second water channel 12 to generate a vertical flow and a spiral flow. Since the water outlet 3 is provided with a rectifying column 31 and water holes 32 separated from each other and surrounding the rectifying column 31, the spiral flow will be blocked by the hole wall of the water hole 32, causing a portion of the water to flow upward to form a spiral flow. The reverse flow flows back toward the top of the second water passage 12. During the backflow process, the reverse flow will be merged with the vertical flow and flow toward the water outlet 3. The rectifying column 31 of the water outlet 3 will cause most of the centrifugal force of the spiral flow to disappear. Finally, under the action of the hole wall of the water hole 32 and the rectifying column 31, the spiral flow and the reverse flow disappear, making the water flow more evenly distributed in the vertical direction. After the evenly distributed water flow passes through the water hole 32 and enters the third water passage 33, the flow rate is more uniform and stable, thereby ensuring that the water jetted outward from the water spray component 0 will not splash outward.

[0031] Specifically, to increase the effective flushing area of the water spray assembly 0, the inner peripheral wall of the mounting cavity 13 is formed into a first curved surface 131, and the outer peripheral wall of the water outlet member 3 located within the mounting cavity 13 is formed into a second curved surface 34. The first curved surface 131 and the second curved surface 34 are adapted to each other, and the water outlet member 3 can rotate along the first curved surface 131 of the mounting cavity 13 under the impact force of water. Specifically, when water from the second water passage 12 flows toward the water outlet member 3, it generates an impact force on the water outlet member 3, causing the water outlet member 3 to swing and rotate within a small range of 360 degrees along the first curved surface 131. This allows the water spray assembly to more freely adjust the water outlet direction, increase the flushing area, more effectively enhance the flushing effect, and ensure the cleanliness of the inside of the toilet. It should be noted that, since a second curved surface 34 is formed on the water outlet part 3, and the gap between the second curved surface 34 and the first curved surface 131 is uniform and very small, it is only necessary to ensure that the water outlet part 3 can be rotated at a small angle in the installation cavity 13. When the water outlet part 3 rotates from one side to the other, the gap between the first curved surface 131 and the second curved surface 34 within the side range is close to zero, the infiltrated water will be discharged, and the drainage water flow and flow rate are small, which will not affect the overall performance of the nozzle assembly 0.

[0032] Specifically, the upper end of the rectifying column 31 is a conical structure, and the upper end surface of the rectifying column 31 is the small end of the conical structure. When the water flows through the first water passage 11 and enters the second water passage 12, a spiral flow is generated. In the middle of the spiral flow, an inward concave water flow is generated. The flow rate of this water flow is relatively high. By setting the rectifying column 31, the inward concave water directly collides with the rectifying column 31. After the collision, the water flow will spread out to the surroundings. At this time, the spiral flow disappears, and the centrifugal force generated by the spiral flow will naturally disappear with the absence of the spiral flow. The water flow flowing to the surroundings due to the collision of the rectifying column 31 will merge with the vertical flow, which can effectively reduce the flow rate of the vertical flow, avoid the splashing of the impact water flow, strengthen the impact force, make it easier to flush dirt, and ensure the cleanliness of the inside and outside of the toilet. The present application sets the upper end of the rectifying column 31 into a conical structure to increase the contact area between the spiral flow and the rectifying column 31, and eliminate the centrifugal force generated by the spiral flow to the greatest extent.

[0033] Specifically, the water holes 32 are formed by a plurality of partitions surrounding the rectifying column 31. The partitions include annular partitions 35 and radial partitions 36. The plurality of annular partitions 35 are arranged in sequence from the inside to the outside. The annular partitions 35 divide the space between the outer wall of the rectifying column 31 and the inner wall of the water outlet 4 into a plurality of annular spaces. A plurality of radial partitions 36 are arranged annularly at intervals in each annular space. The radial partitions 36 in each annular space divide the annular space into a plurality of water holes 32. The annular partitions 35 and radial partitions 36 are both perpendicular to the horizontal plane, thereby making the water holes 32 arranged vertically downward. The present application can block the water flow by setting the partitions, causing part of the water flow to form a reverse flow upward. During the reverse flow, it merges with the vertical flow and flows toward the water outlet 3, reducing the water flow rate, avoiding congestion and interference between the water flows, and improving the integrity and stability of the water flow when passing through the water spray assembly 0. In addition, because the spiral flow will directly collide with the rectifying column, it will generate a large impact force. The partitions arranged at different intervals can improve the structural strength and stability of the partitions. The present application does not limit the number of water holes and the thickness of the partition, and those skilled in the art can make a selection based on specific experimental results.

[0034] Specifically, a confluence groove 37 is formed above the water hole 32 in the water outlet part 3, and the upper end of the rectifying column 31 is located in the confluence groove 37. The water flows from the second water flow channel 12 to the water outlet part 3, first enters the confluence groove 37, and the spiral flow located above the rectifying column 31 collides with the rectifying column 31 in the confluence groove 37 and then spreads to the surroundings, also falling directly into the confluence groove 37, and then enters the third water flow channel 33 through the water hole. Since the cross-sections of the water flow hole 32 and the third water flow channel 33 are both vertical surfaces, the water flows more smoothly and the flow rate is more uniform, further ensuring that the water jetted outward will not splash out.

[0035] Specifically, the outer wall of the nozzle body 1 is provided with a rib 14 that abuts the nozzle cover 2. A first external thread is provided on the outer wall of the nozzle body 1, below the rib 14. The nozzle cover 2 is provided with a first internal thread that is threadedly connected to the first external thread. The nozzle cover 2 is threadedly connected to the first external thread via the first internal thread. A sealing ring 5 is provided between the nozzle cover 2 and the water outlet 3. This sealing ring 5 ensures a tight seal between the nozzle cover 2 and the water outlet 3, preventing water from flowing out of the gap between the nozzle body 1 and the water outlet 3, and preventing water from flowing out of the gap between the nozzle body 1 and the water outlet 3.

[0036] Specifically, a second external thread is provided on the outer wall of the nozzle body 1 above the rib 14, and the second external thread is located on the outer wall of the second water flow channel 12. A sealing gasket 5 and a locking nut 6 are screwed on the second external thread in sequence. The locking nut 6 and the sealing gasket 5 are used to install the water spray assembly 0 of the present application on the toilet body 8; and the outer wall of the first water flow channel 11 is a connecting part, which is used to connect with the connecting pipe 7. When in use, the connecting pipe 7 is inserted into the connecting part to direct the water flow into the first water flow channel 11.

[0037] The present invention also provides a toilet, comprising a toilet body 8 and a water spray assembly 0 mounted on the toilet body 8. The toilet provided in this application adopts all the technical solutions of all the above-mentioned embodiments of the water spray assembly, and thus has at least all the beneficial effects brought about by the technical solutions of the embodiments of the water spray assembly, which will not be described in detail here.

[0038] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
