In the self-cleaning bubbler, the inner core is rotatably installed in the outer casing 1, and when the inner core is rotated to rotate to the first position in the outer casing 1, the first water port communicates with the water outlet 11 and the second water The molding port communicates with the water inlet 12, and the water in the pipeline enters the water passage from the second water molding port, and then flows out of the first water molding port. When the inner core is rotated to rotate to the second position in the casing 1, The first water port is connected to the water inlet 12 and the second water port is connected to the water outlet 11. The water in the pipeline enters the water passage from the first water port, and then flows out from the second water port to achieve water discharge. Switch. Both the first water port and the second water port have the functions of water inlet and outlet. When the bubbler needs to be cleaned, it can be cleaned by the circulating water by switching the position of the inner core in the shell 1. The entire cleaning process Simple and time-consuming, no need to disassemble the bubbler, there will be no missing parts and the problem of reducing the bubbler's tightness.

The water outlet types of the first water port and the second water port can be the same (for example, both shower water or bubble water can be used), or they can be different. For example, the first water port and the second water port are any two of a bubble water port, a shower water port, a spray water port, and the like. The inner core and the outer shell 1 can be rotated and matched by a spherical mating structure, that is, the inner core can be rotated in the outer shell 1.

Exemplarily, as shown in FIG. 3, FIG. 4, FIG. 8 and FIG. 9, the surfaces on the inner core where the first water-shaped opening and the second water-shaped opening are provided (that is, both end surfaces of the inner core) are flat (two The planes can be set to be parallel to each other), and the side surface of the inner core located between the two planes is a spherical surface. The inner surface of the casing 1 has a mating surface that realizes a rotational fit with the spherical side surface of the inner core. The inside of the casing 1 may be spherical or cubic. One of the inner surface of the outer casing 1 and the outer surface of the inner core may have a spherical structure to realize rotation.

In the first exemplary embodiment, as shown in FIGS. 1 to 4, the inner core includes a second water-type housing 31 having a top wall and an annular side wall, and a second water-type port is provided on the top wall. 22; and a first water-type component 32 installed in the second water-type case 31, and a water storage cavity 33 is formed between the first water-type component 32 and the second water-type case 31, and the first water-type component 32 The first water-type port 23 is located at the bottom opening of the second water-type shell 31, and the water storage cavity communicates with the second water-type port 22 and the first water-type port 23. The first water-type port 23 may be a spray water port, and the second water-type port 22 may be a shower water port. The shower spout may be a plurality of circular holes spaced along the top wall of the second water-type casing 31 in the circumferential direction.

The inner core may further include a fixing member 34 installed in a bottom opening of the second water type casing 31, and the fixing member 34 restricts the first water type component 32 from coming out of the second water type.壳 31。 The housing 31. The fixing member 34 is a ring-shaped structure, which is sleeved on the first water type module 32 and can be screwed and fixed in the bottom opening of the second water type casing 31. The fixing member 34 is opposite to the first water type module. 32 is limited to prevent it from coming out of the second water-type casing 31.

In order to increase the water output of the bubbler when the water type of the bubbler is a certain water type, for example, a limiting groove 341 is formed on the inner surface of the fixing member 34 (that is, two are arranged on the inner surface of the fixing member 34 at intervals. The convex ring, because the two convex rings are convex compared to the inner side of the fixing member 34, the two convex rings and the inner side portion of the fixing member 34 located between the two convex rings form the limiting groove 341) The two side walls of the limiting groove 341 (that is, the inner walls of the two convex rings) cooperate with the outer side surface of the first water type component 32, and may or may not contact the outer surface of the first water type component 32. A first water passage 342 is provided on the bottom wall of the limiting groove 341 (that is, a part of the side wall of the fixing member 34 between the two convex rings), and the first water passage 342 is in communication with the water storage cavity 33.

The blade 43 moves to open the water increasing hole 451, and the water flow enters from the second water profile port 22 and the water increasing hole 451, and then is sprayed into the water storage cavity 44 through the water ejection plate 43. The negative pressure formed by the water jet will generate suction and make the outside world The air enters the water storage cavity 44 from the water outlet 11 and the air inlet, and is mixed with the water in the water storage cavity 44 and finally passes through the turbulence plate 42 from the first water type port (such as a bubble water port) 21 (at this time, the first The first water port 21 is located in the water outlet 11 of the housing 1), and completes the function of the second water port 22 (such as shower water) to the first water port 21 (such as bubble water). Switch (simultaneously flush out the dirt accumulated in the bubbler when the shower water is flushed out). The turbulence sheet 42 can fully mix the water flow and the air, and enhance the water outlet effect of the bubble water.

When the inner core rotates 180 degrees, that is, when the inner core rotates to the second position in the casing 1, as shown in FIG. 9, the water flow enters the blistering from the first water port (for example, the bubble water port) 21 and the air inlet. After the turbulence plate 42 and the water ejection plate 43 pass through, the blocking member 46 is pressed against the fixing member 45 by the water pressure, and the water increasing hole 451 is blocked. The water in the bubbler comes from the second water port (for example, The shower water outlet) 22 flows out (at this time, the second water profile opening 22 is located in the water outlet 11 of the housing 1), and the water from the first water profile opening 21 (such as bubble water) to the second water profile opening 22 is realized. Type (such as shower water) function switching (contamination accumulated in the bubbler when the bubble water is flushed out at the same time).

As shown in FIG. 5, FIG. 8 and FIG. 9, a sealing member 49 may be provided on the blocking member 46 to improve the sealing performance, and a sealing member 49 and a check ring 48 may also be provided on the water inlet 12 of the housing 1 to improve Performance of bubbler.

The water in the pipeline enters the water passage from the second water port, and then flows out from the first water port. Rotate the inner core to rotate it in the casing to In the second position, the first water port is connected to the water inlet, and the second water port is connected to the water outlet. The water in the pipeline enters the water passage from the first water port, and then flows out from the second water port. To achieve water switching. Both the first water port and the second water port have the functions of water inlet and outlet. When the bubbler needs to be cleaned, it can be cleaned by circulating water by switching the position of the inner core in the shell. The whole cleaning process is simple and convenient. Short time consuming, there is no need to disassemble the bubbler, there will be no missing parts and problems of reducing the sealability of the bubbler.
