[0002] Chinese patent 202311803900.5 (published on February 9, 2024) discloses a bubbler that can switch between two water splash effects by flipping the inner core of the bubbler. One of the water splashes is bubble water, which is inhaled through the air inlet channel when the water comes out, so that water and air are mixed in the inner core of the bubbler to form bubble water. Based on this patent, how to make the bubble effect better and make the air and water flow more fully mixed is the current research focus.

[0003] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0006] A bubbler inner core, comprising an inner core body, a first water flow panel and a second water flow panel, wherein the first water flow panel and the second water flow panel respectively have a first water flow hole and a second water flow hole; the inner core body has a spherical outer wall and a water flow inner cavity, the water flow inner cavity communicates with the first water flow panel and the second water flow panel; the first water flow panel extends into the water flow inner cavity to form an inner surrounding wall, the inner surrounding wall is integrally connected to the inner side wall of the inner core body through a connecting portion, and an air suction channel is formed between the inner surrounding wall and the inner side wall of the inner core body; the second water flow panel is fixedly connected to the inner core body;

[0007] The second water-passing panel extends into the water-passing inner cavity to form at least two guide rings from inside to outside, and the guide rings are all located inside the inner surrounding wall. The second water-passing panel between two adjacent guide rings has a plurality of second water-passing holes.

[0008] Furthermore, the extension height of the guide ring increases gradually from the outside to the inside, the lower edge of the guide ring of the outermost circle is higher than the upper edge of the inner surrounding wall, and the lower edges of the remaining guide rings are lower than the upper edge of the inner surrounding wall.

[0009] Furthermore, the guide ring includes a first guide ring, a second guide ring and a third guide ring from the inside to the outside; an inclined flow channel is formed at the lower part of the outer wall of the second guide ring, and the intersection of the extension line of the inclined flow channel and the inner surrounding wall is lower than the lower edge of the inner surrounding wall.

[0010] Furthermore, a first inner inclined ring is formed at the junction between the inner side wall of the inner peripheral wall and the upper edge of the inner peripheral wall; and a first outer inclined ring facing the first inner inclined ring is formed at the lower part of the outer side wall of the third guide ring.

[0011] Furthermore, a second inner inclined ring is formed at the lower portion of the inner side wall of the second guide ring.

[0012] Furthermore, the outer surface of the second water-passing panel has a central convex surface, and part of the second water-passing holes penetrates the central convex surface.

[0013] Furthermore, a center column is formed at the center of the second water-passing panel extending toward the water-passing inner cavity; and a plurality of second water-passing holes are arranged on the second water-passing panel between the center column and the innermost guide ring.

[0014] Furthermore, the inner surface of the first water-passing panel is an inner concave surface, and the central column extends into a spherical space formed by the inner concave surface.

[0015] Furthermore, the outer surface of the second water-passing panel also has an outer wall surrounding the outer sides of all the second water-passing holes; the second water-passing panel is buckled and fixedly connected to the inner core body.

[0016] A water outlet device comprises a water outlet and the above-mentioned bubbler inner core; the bubbler inner core is rotatably arranged at the water outlet; when the first water flow panel is located at the water outlet side, the second water flow panel is located at the water inlet side, or when the second water flow panel is located at the water outlet side, the first water flow panel is located at the water inlet side; when the first water flow panel is located at the water outlet side, water flows out of the first water flow hole to produce bubble water; when the second water flow panel is located at the water outlet side, water flows out of the second water flow hole to produce shower water.

In this way, more air can be sucked in through the air intake channel to mix with the water flow, forming bubble water with richer bubbles.

[0019] Second, the lower edge of part of the guide ring is lower than the upper edge of the inner wall, so that a negative pressure area can be formed at the lower inner side of the inner wall, guiding the air to pass over the inner wall into the water flow cavity and mix with the water flow.

[0020] 3. The extension height of the guide ring gradually increases from the outside to the inside, and the lower edge of the guide ring of the outermost circle is higher than the upper edge of the inner wall; in this way, when the first water flow panel is located on the water inlet side and the second water flow panel is used as the water outlet side, the water flow through the air intake channel on the first panel can also conveniently reach the first water flow hole inside the outermost guide ring for discharge.

[0021] Fourth, the outer wall on the second water-passing panel plays the role of converging water flow, so that the water flow is concentrated through the second water-passing hole.

[0022] Compared with the prior art, the utility model provides a plurality of guide rings, and the second water through hole is located between two adjacent guide rings. In this way, the water flow through the second water through hole can more easily form a negative pressure in the area between the two adjacent guide rings, so that the inner core of the bubbler inhales more air through the air intake channel, thus forming bubble water with rich bubbles.

[0039] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0040] like Figures 1 to 11 As shown, it is a bubbler inner core involved in the utility model, comprising an inner core body 1, a first water flow panel 2 and a second water flow panel 3, wherein the first water flow panel 2 and the second water flow panel 3 respectively have a first water flow hole 21 and a second water flow hole 30; the inner core body 1 has a spherical outer wall 11 and a water flow inner cavity 12, wherein the water flow inner cavity 12 communicates with the first water flow panel 2 and the second water flow panel 3; the first water flow panel 2 extends into the water flow inner cavity 12 to form an inner surrounding wall 22, wherein the inner surrounding wall 22 is integrally connected to the inner side wall of the inner core body 1 through a connecting portion 13, and an air suction channel 14 is formed between the inner surrounding wall 22 and the inner side wall of the inner core body 1; the second water flow panel 3 is fixedly connected to the inner core body 1;

[0041] The second water flow panel 3 extends into the water flow inner cavity 12 to form at least two guide rings from inside to outside. The guide rings are located inside the inner surrounding wall 22. The second water flow panel 3 between two adjacent guide rings has a plurality of second water flow holes 30.

[0042] In this way, the utility model involves a bubbler inner core and a water outlet device, which are provided with at least two circles of guide pipes and a second water hole 30 between two adjacent guide circles. In this way, it is easier to form a negative pressure when the water flows downward through the second water hole 30 passes between the adjacent guide circles. In this way, more air can be sucked in through the air intake channel 14 to mix with the water flow, forming bubble water with richer bubbles.

[0043] Preferably, the extension height of the guide ring increases gradually from the outside to the inside, the lower edge of the guide ring of the outermost circle is higher than the upper edge of the inner surrounding wall 22, and the lower edges of the remaining guide rings are lower than the upper edge of the inner surrounding wall 22. The lower edges of some guide rings are lower than the upper edge of the inner surrounding wall 22, so that a negative pressure area can be formed at the lower inner side of the inner surrounding wall 22, guiding the air to pass over the inner surrounding wall 22 and enter the water passage cavity 12 to mix with the water flow.

[0044] The lower edge of the guide ring of the outermost circle is higher than the upper edge of the inner wall 22; in this way, when the first water flow panel 2 is located on the water inlet side and the second water flow panel 3 is used as the water outlet side, the water flow through the air intake channel 14 on the first panel can also conveniently reach the first water flow hole 21 inside the outermost guide ring for discharge.

[0045] Specifically, the guide ring includes a first guide ring 31, a second guide ring 32 and a third guide ring 33 from the inside to the outside; the lower edge of the third guide ring 33 of the outermost circle is higher than the upper edge of the inner wall 22; the lower edges of the first guide ring 31 and the second guide ring 32 are lower than the upper edge of the inner wall 22 (both are referenced when the second water-passing panel 3 faces upward). An inclined flow channel 322 is formed at the lower part of the outer wall of the second guide ring 32, and the intersection of the extension line of the inclined flow channel 322 and the inner wall 22 is lower than the lower edge of the inner wall 22. In this way, the water flowing through the inclined flow channel 322 is ejected outward and downward, and is guided downward by the inner wall of the inner wall 22, so that a negative suction pressure is generated inside the inner wall 22, and the air is mixed with the water flow after turning upward through the suction channel 14 to form bubble water.

[0046] Preferably, a first inner inclined ring 221 is formed at the junction of the inner side wall of the inner surrounding wall 22 and the upper edge of the inner surrounding wall 22; a first outer inclined ring 331 facing the first inner inclined ring 221 is formed at the lower part of the outer side wall of the third guide ring 33. The first inner inclined ring 221 can better guide the water flow from the inclined flow channel 322, and the first outer inclined ring 331 cooperates with the first inner inclined ring 221 to make the air pass more smoothly.

[0047] Preferably, a second inner inclined ring 321 is formed at the lower portion of the inner wall of the second guide ring 32. In this way, when the first water-passing panel 2 is located at the water inlet side and the second water-passing panel 3 is used as the water outlet side, water can easily flow between the first guide ring 31 and the second guide ring 32 to enter the second water-passing hole 30.

[0048] Preferably, the outer surface of the second water-passing panel 3 has a central convex surface 34, and part of the second water-passing holes 30 penetrate the central convex surface 34. In this way, even if there is mud and sand, the mud and sand will first be concentrated outside the central convex surface 34, so it is not easy to completely block the second water-passing holes 30.

[0049] Preferably, the center of the second water-passing panel 3 extends toward the water-passing inner cavity 12 to form a central column 35; a plurality of second water-passing holes 30 are arranged on the second water-passing panel 3 between the central column 35 and the innermost first guide ring. The central column 35 is equivalent to the innermost solid guide ring, and the central column 35 reduces the volume of the water-passing inner cavity 12, so that the negative pressure generated by the water flow is stronger, thereby improving the air suction effect. Furthermore, the inner surface of the first water-passing panel 2 is an inner concave surface, and the central column 35 extends to the inner concave surface to form a spherical space 23.

[0050] Preferably, the outer surface of the second water-passing panel 3 further comprises an outer wall 36 surrounding the outer sides of all the second water-passing holes 30; the second water-passing panel 3 is buckled and fixedly connected with the inner core body 1. The outer wall 36 on the second water-passing panel 3 plays the role of converging water flow, so that the water flow passes through the second water-passing holes 30 in a concentrated manner.

[0051] The utility model also provides a water outlet device, including a water outlet end 110 and the above-mentioned bubbler inner core; the bubbler inner core is rotatably arranged at the water outlet end 110; when the first water pass panel 2 is located at the water outlet side, the second water pass panel 3 is located at the water inlet side, or when the second water pass panel 3 is located at the water outlet side, the first water pass panel 2 is located at the water inlet side; when the first water pass panel 2 is located at the water outlet side, the first water pass hole 21 discharges water to produce bubble water; when the second water pass panel 3 is located at the water outlet side, the second water pass hole 30 discharges water to produce shower water. The water outlet end 110 is formed on the water outlet housing 100.

[0052] Compared with the prior art, the utility model provides a plurality of guide rings, and the second water through hole 30 is located between two adjacent guide rings. In this way, the water flow through the second water through hole 30 can more easily form a negative pressure in the area between the two adjacent guide rings, so that the inner core of the bubbler inhales more air through the air intake channel 14, thereby forming bubble water rich in bubbles.

[0053] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
