Description

Technical Field

[0001] The invention relates to the technical field of toilets, and in particular to a vortex flushing water outlet structure and a toilet. Background Art

[0002] The vortex water outlet method is already a common toilet flushing method; in the prior art, the vortex water outlet adopts the form of a water inlet head and a water flow cavity, the water inlet head is connected to the inner cavity of the water flow cavity, and a water outlet hole is opened on the water flow cavity, forming a water inlet head-water flow cavity-water outlet hole water outlet method. The above-mentioned vortex water outlet structure can only see the water outlet hole from the appearance, thereby ensuring the aesthetics of the toilet.

[0003] When the above-mentioned water inlet head and water flow cavity are adopted, there is a large gap from the water inlet head to the top of the water inlet cavity. At the same time, in order to prevent stagnant water in the water flow cavity, the water outlet hole is generally close to the bottom of the water flow cavity. The above factors lead to the presence of gas above the water flow cavity for a long time in actual use. This part of the gas will be driven out of the water outlet hole by the water flow, forming a mixed spray mode of water and gas, which will cause continuous noise. Summary of the invention

[0004] The purpose of the present invention is to provide a vortex flushing water outlet structure and a toilet to reduce the continuous noise impact caused by the vortex flushing.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] The vortex water outlet structure includes a water passage cavity surrounded by a side wall, a top wall and a bottom wall, wherein the side wall is provided with a relative inlet and a first cavity outlet; the vortex water outlet structure also includes:

[0007] A water inlet head is provided with a water spray port, and the water inlet head is plugged into the inlet so that the water spray port is located in the water passage cavity, and the water spray port is at least partially facing the top wall.

[0008] In some embodiments, the top wall of the water flow cavity located above the first outlet has a first inclined surface, the water spray outlet at least partially faces the first inclined surface, and the distance between the first inclined surface and the bottom wall gradually increases from close to the first outlet to close to the inlet.

[0009] In some embodiments, the water spray port of the water inlet head faces the first inclined surface.

[0010] In some embodiments, the water spray outlet is a bell-shaped mouth that expands toward the top wall.

[0011] In some embodiments, the inlet is provided with a sealing rubber plug, and the water inlet head is sealed and penetrated through the sealing rubber plug.

[0012] In some embodiments, a second outlet cavity is further provided on the side wall, and the second outlet cavity is set at an angle with the first outlet cavity. The vortex water outlet structure is also provided with a partition plate, and the first end of the partition plate is fixedly inserted in the water spray port, and the second end of the partition plate protrudes from the water spray port and is provided with a first bent portion bent in the direction of the second outlet cavity. The partition plate divides the water spray port into a first nozzle and a second nozzle set at an angle, and at least part of the first nozzle faces the top wall, and the second nozzle faces the second outlet cavity.

[0013] In some embodiments, the opening direction of the second outlet is horizontal and is arranged at the intersection of the side wall and the bottom wall of the water flow cavity. The second nozzle faces the bottom wall, and the angle between the opening direction of the second nozzle and the horizontal direction is 20°-40°.

[0014] In some embodiments, a surface of the partition plate facing away from the second nozzle is a second inclined surface, and an inclination of the second inclined surface gradually increases from the first end of the partition plate to the second end of the partition plate.

[0015] In some embodiments, the second end of the partition plate is provided with a second bent portion bent in a direction away from the second nozzle.

[0016] A toilet is also provided, comprising a toilet body, on which the vortex flushing water outlet structure as described above is arranged.

[0017] Beneficial effects of the present invention:

[0018] When the water inlet head injects water into the water flow cavity, at least part of the water flow is sprayed toward the top wall through the water nozzle, so that part of the water flows to the upper space between the water inlet head and the top wall, quickly filling up the space. Therefore, only in the initial stage of water injection does air and water mix and noise appears briefly. When the upper space between the water inlet head and the top is filled, there is no air inside, so there will be no mixing of water and air, eliminating subsequent noise, thereby reducing the continuous noise impact caused by vortex.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] like Figures 1 to 7 As shown, the present application provides a vortex water outlet structure, which includes a water flow cavity 1 surrounded by a side wall 11, a top wall 12 and a bottom wall 13, and the vortex water outlet structure also includes a water inlet head 2, and a relative inlet 14 and a first outlet 15 are provided on the side wall 11 of the water flow cavity 1, and the water inlet head 2 is provided with a water spray port 21, and the water inlet head 2 is plugged into the inlet 14 so that the water spray port 21 is located in the water flow cavity 1, and the water spray port 21 is at least partially facing the top wall 12 of the water flow cavity 1.

[0039] Part of the water spray port 21 of the water inlet head 2 faces the top wall 12. When the water inlet head 2 injects water into the water cavity 1, at least part of the water flow is sprayed toward the top wall 12 through the water spray port 21, so that part of the water flows to the upper space between the water inlet head 2 and the top wall 12, and the space is quickly filled. Therefore, only in the initial stage of water injection, there is a mixed spray of air and water, and noise occurs briefly. When the upper space between the water inlet head 2 and the top wall 12 is filled, there is no air inside, and the phenomenon of water and air mixing will not occur, thereby eliminating the subsequent noise and reducing the continuous noise impact caused by vortex.

[0040] like Figure 2 and Figure 3As shown, in some embodiments, the top wall 12 of the water flow cavity 1 above the first outlet port 15 has a first inclined surface 16, and the distance between the first inclined surface 16 and the bottom wall 13 of the water flow cavity 1 gradually increases from the direction close to the first outlet port 15 to the direction close to the inlet 14, and the water spray port 21 at least partially faces the first inclined surface 16. The setting of the above-mentioned first inclined surface 16, on the one hand, when the water flow hits the first inclined surface 16, part of the water flow can be more smoothly introduced into the upper space between the water inlet head 2 and the top wall 12, thereby improving the filling speed; on the other hand, it can also make part of the water flow flow toward the first outlet port 15 along the first inclined surface 16, so that the water flow flowing out of the first outlet port 15 has a downward pressure tendency, thereby reducing continuous noise while also reducing the possibility of splashing.

[0041] like Figure 2 As shown, in some embodiments, the water inlet 21 of the water inlet head faces the first inclined surface 16, that is, all the water flows entering the water passage cavity 1 through the water inlet 21 hit the first inclined surface 16 first for diversion. Figure 3 As shown, in other embodiments, the water spray outlet 21 is a bell-shaped mouth that expands toward the top wall 12, so that at least part of the water flow sprayed from the water spray outlet 21 is transported along a horizontal straight line, while the other part can be sprayed toward the first inclined surface 16, thereby guiding the water flow to the first inclined surface 16 for diversion.

[0042] It should be noted that the inlet 14 is provided with a sealing rubber plug 3, and the water inlet head 2 is sealed and penetrated through the sealing rubber plug 3, so as to seal the inlet 14 and prevent water leakage. The sealing rubber plug 3 can be provided at the inlet 14 in a snap-fit ​​manner, but is not limited to.

[0043] like Figures 4 to 7As shown, in some embodiments, a second cavity outlet 17 is further provided on the side wall 11 of the water passage cavity 1, and the first cavity outlet 15 and the second cavity outlet 17 are set at an angle, so as to form a double vortex structure, which is different from a single vortex flushing with a first cavity outlet 15. In view of the above-mentioned situation of setting two outlets, the first cavity outlet 15 and the second cavity outlet 17, the vortex flushing water outlet structure is also provided with a partition plate 4, the partition plate 4 has a first end and a second end opposite to each other, the first end of the partition plate 4 is fixedly inserted in the water spray port 21, and the fixing form of the partition plate 4 and the water inlet head 2 is not specifically limited, and can be a welding connection. In some alternative embodiments, the partition plate 4 can also be integrally formed with the water inlet head 2. The second end of the partition plate 4 protrudes from the water spray port 21, and a first bending portion 5 bent toward the second cavity outlet 17 is provided at the second end of the partition plate 4, and the first bending portion 5 and the partition plate 4 are L-shaped, and the first bending portion 5 and the partition plate 4 can also be integrally formed. The partition plate 4 divides the water outlet 21 into a first outlet 211 and a second outlet 212. At least part of the first outlet 211 faces the first inclined surface 16 of the top wall 12, while the second outlet 212 faces the second outlet 17, thereby directing part of the water flow to the second outlet 17 to form a double vortex.

[0044] Furthermore, the opening direction of the second outlet port 17 is horizontal and is arranged at the junction of the side wall 11 and the bottom wall 13 of the water flow cavity 1, so as to reduce the retained dead water; accordingly, the second nozzle 212 faces the bottom wall 13, and the angle between the opening direction of the second nozzle 212 and the horizontal direction is 20°-40°. By setting the above angle, the possibility of water flowing out of the second nozzle 212 directly hitting the side wall 11 is reduced, so that the water flow out of the second nozzle 212 hits the bottom wall 13 by tilting, and passes through the horizontally arranged second outlet port 17 as quickly as possible, thereby reducing water resistance.

[0045] like Figure 6 As shown, in some embodiments, the side of the partition plate 4 facing away from the second nozzle 212 is a second inclined surface, and the inclination of the second inclined surface gradually increases from the first end of the partition plate 4 to the second end of the partition plate 4, so that the water flow to the first outlet 15 is further inclined upward, quickly filling the upper space between the water inlet head 2 and the top wall 12, and quickly reducing noise. Figure 7 As shown, in some alternative embodiments, the second end of the partition plate 4 is provided with a second bent portion 6 bent away from the second nozzle 212, so that the water flow is guided upward through the second bent portion 6, which also plays a role in rapid noise reduction. In the current embodiment, the second bent portion 6 is integrally formed with the partition plate 4.

[0046] It should be noted here that when the first bending portion 5 and the second bending portion 6 are provided, one side of the first bending portion 5 and the second bending portion 6 facing the first end of the partition plate 4 is an arc-shaped surface, thereby being able to guide the water flow more smoothly and reduce the possibility of forming turbulence.

[0047] In some embodiments, when the water inlet head 2 is arranged at the inlet 14, the water spray port 21 can also be offset to the side away from the second outlet port 17, so that the water flow can be closer to the pot surface when flowing out from the first outlet port 15, and the splash-proof effect is better.

[0048] The present invention also provides a toilet, which includes a barrel body 7, the barrel body 7 has a pot surface, and the barrel body 7 is provided with the above-mentioned vortex water outlet structure, which guides the water in the water passage cavity to the pot surface, thereby reducing the continuous noise and splashing effects caused by the vortex.

[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
