[0032] DETAILED DESCRIPTION OF EMBODIMENT

[0033] The present invention appears more clearly during the detailed description which follows with reference to the attached drawings.

[0034] The present invention relates to a toilet bowl with vortex current flushing comprising a toilet bowl body 1, the toilet bowl body 1 comprising a top panel, an annular channel 2, a container body 3, a cap head 5 and a drain pipe 10. The annular channel 2 is located at the upper part of the toilet bowl body 1 and is connected to the top panel of the toilet bowl body 1, the lower edge of the annular channel 2 is connected to a conical annular-shaped current guide groove 9, and the lower edge of the current guide groove 9 extends and is connected to the container body 3 to form a smooth conical arc surface.The annular channel 2 is an annular structure, a water outlet hole 4 is provided on the side wall of the annular channel 2 close to the inner cavity of the toilet bowl body 1, and the water flowing out of the water outlet hole 1 washes the container body 3 along the current guide groove 9 to provide a vortex flushing effect. The outer side of the water outlet hole 4 is . provided with a water retaining edge 41, such water retaining edge 41 is used to prevent overflow of a part of the water caused by excessive water flow from the flushing hole, thereby solving the problem of water overflow and promoting the control of the flushing angle. Preferably, the junction between the water retaining edge 41 and the annular channel 2 is designed for rounding and the rounding angle range is between 55° to 70°.

[0035] The container body 3 is a funnel-shaped structure, which promotes downward flushing and increases the flow rate of the water; the bottom of the container body 3 is provided with a cap head 5 and the cap head 5 is in communication with the drain pipe 10. Preferably, the diameter of the drain pipe 10 is less than or equal to 65 mm.

[0036] Example 1

[0037] As shown in Figures 1 to 4 (In order to better show the change of the radian of the product, the scanning profile of the actual object is mounted by a dotted line inside), an angle between a connection of the center of the circle of the water outlet hole 4 to the center of the cross-section of the annular channel 2 on the plane where the water outlet hole 4 is located and the symmetrical axis of the toilet bowl on the plane where the center of the circle of the water outlet hole 4 is located is less than 60°; after an annular toilet bowl cover plate is mounted, because the inner diameter of the cover plate is smaller than the inner diameter of the upper panel of the toilet bowl body, the water outlet hole 4 is hidden by the cover plate and invisible to the user when standing in front of the toilet bowl, thus improving the aesthetics of the toilet bowl.

[0038] The container body 3 is a funnel structure with the inner wall in a volute shape, and the starting point of the volute spiral is smoothly connected without clearance to the flow guide groove 9, and the ending point of the volute spiral corresponds to the connecting position between the container body 3 and the cap head 5. The junction between the container body 3 and the cap head 5 has a stepped structure, i.e., the left height is greater than the right height or the right height is greater than the left height.This junction corresponds to the outlet position of the container body 3, and the inner wall of the container body on both sides of the outlet has different heights, when the toilet bowl is observed from the point of view of normal use, the left side or the right side of the container body is higher than the opposite side, which forms a difference of rotation levels at different heights, ensures that the water current enters the hat head 5 smoothly with the dirt, avoids the phenomenon that the water current only performs rotation without going down and the phenomenon of the water current swinging left and right in the container body 3. In [Fig.3], the height of the left side of . outlet 31 is greater than the height of the outlet right side 32. In some preferred embodiments, the front wall 6 of the container body outlet is an arc surface, and the radian of the cross-section of the arc surface is less than jt / 6, such arc surface is close to the vertical plane, which is different from the large radian surface of existing vortex flush toilet bowls and effectively prevents the water that is ejected from the container body 3 to the hat head 5 from splashing outward. In the present example, the arrangement without a clearance hole also reduces the occurrence of splashing and overflow.

[0039] From the point of view of [Fig.3], the top of the hat head 7 has a large radian arc structure, in particular, the radian preferably lies between ir / 4 to jt / 2, compared to a traditional top of the hat head close to a plane whose radian is strictly less than the radiant of the top of the hat head 7 of the present solution; the pipe diameter of the hat head 5 is strictly less than the outlet of the bowls of traditional toilets, therefore, when the hat head is filled with water, a siphon phenomenon occurs in the hat head under the effect of pressure, and the upper surface with a large radian also allows the flushing phenomenon to occur, so that the hat head 5 performs the dual role of siphon and flushing, thus greatly improving the dirt purging effect.

[0040] When in use, the water current in the water tank flows along the annular channel 2 to the water outlet hole 4, exits obliquely from the water outlet hole 4, washes the container body 3 along the current guide groove 9 to the outlet at the bottom of the container body, due to the inner wall of the container body at the outlet of the container body having different heights on two sides, a spiral channel inclined to the cap head 5 is formed, and the water current enters the cap head 5 smoothly, thereby solving the problem that the water current only rotates without descending.

[0041] Example 2

[0042] As shown in Figures 5 and 6, when the junction between the container body 3 and the cap head 5 has the same left height and right height, the toilet bowl body 1 also comprises a main waterway 11 and an auxiliary waterway 13, the annular channel 2 on the side of the water outlet hole 4 is provided with a cavity, and the cavity is the main waterway 11; and the annular channel 2 on the other side of the water outlet hole 4 is a blocking structure, which can increase the water pressure at the water outlet hole 4 and facilitate flushing.

[0043] A water inlet hole 8 is provided above the rear portion of the toilet bowl body 1, and the water inlet hole 8 is provided above the rear portion of the main waterway 11. An auxiliary waterway 13 is formed between the toilet bowl body 1 and the upper part of the container body 3, and the front part of the main waterway 11 is in communication with the annular channel 2 and the auxiliary waterway 13 respectively. The side wall of the container body on which the auxiliary waterway 13 is located is provided with an inclined jet hole 12, the position of the original clearance hole has been changed, and the inclination angle of the clearance hole 12 enables the water stream ejected from the clearance hole 12 to aim at the lower position of the hat head 5 and flush it.Preferably, the jet hole 12 is a flat oval hole, that is, the length in the left and right direction is greater than the length in the up and down direction, and the water outlet width in the left and right direction is consistent with the water covering width, which increases the surface area of ​​the water covering the product and promotes the passage of the medium.

[0044] When in use, the water stream enters the main waterway 11 through the water inlet hole 8, and then is divided into two water streams, one water stream passes through the annular channel 2 and is ejected from the water outlet hole 4 at the front end of the annular channel 2, and then washes the container body along the flow guide groove 9; the other water stream passes through the auxiliary waterway 13, ejected from the clearance hole 12 and enters the cap head 5, the two water streams mix to achieve flushing on the flow guide groove 9, the container body 3 and the cap head 5, thereby solving the problem of dirt adhering to the container body 3 and the annular channel 2 of the existing toilet bowl.

[0045] Example 3

[0046] Combining Example 1 and Example 2, that is, the junction between the container body 3 and the cap head 5 has a stepped structure with the left side or the right side higher than the opposite side, the rear side wall of the container body 3 is provided with an inclined jet hole 12, and the jet hole 12 is oriented toward the bottom of the cap head 5.

[0047] Compared with other existing flush toilet bowls, the present invention has the following advantages:

[0048] (1) Easy to clean: The existing toilet bowl is generally a product with circular holes or opposite holes, dirt often accumulates at the holes and is not easy to remove, on the contrary, the vortex flush toilet bowl of the present invention is provided with a funnel-shaped container body and is easy to brush.

[0049] (2) Good visual effect: dirt often accumulates at the circular holes of the existing toilet bowl, which are difficult for the user to accept after long-term use, on the contrary, the water outlet position of the toilet bowl The toilet of the present invention is located at the front part of the product and is invisible to the user, and a water retaining edge is provided, which is also invisible.

[0050] (3) The diameter of the product pipe is smaller than that of the toilet bowl with ordinary flushing: when the current passes through the funnel-shaped container body, it produces acceleration and flows downwards from the hat head, thanks to the high flow rate, the pipe is easy to fill, which can temporarily provide a siphon effect and accelerate the purging of dirt.

[0051] (4) The connecting structure between the jet hole and / or the stepped container body and the Hat head solves problems of incomplete rinsing and overflow.

[0052] Of course, the present invention is not limited to the description of the above embodiment, which is only the preferred embodiment. It should be noted that all equivalent substitutions and obvious modifications made by any person familiar with this field, according to the teachings of this description fall within the essential scope of this description and must be protected by the present invention.
