Example 1:

referring to fig. 1, the present invention provides a three-way structure, which includes a body 10 and a filtering assembly 20.

The main body 10 is a main and auxiliary pipe structure, which may be formed in a split manner or in an integral manner. The main body 10 includes a main pipe 12 and an auxiliary pipe 14, both of which are circular pipes, wherein one end of the main pipe 12 is provided with a water inlet 122, the other end is provided with a first water outlet 124, the auxiliary pipe 14 is perpendicular to the main pipe 12, and the end is provided with a second water outlet 142. In other examples, the secondary pipe 14 may be inclined at other angles to the primary pipe 12. In use, water (or other liquid) flows in from the water inlet 122 and then out of the first and second water outlets 124, 142. Optionally, the end of the auxiliary pipe 14 is provided with a thread 144 on the outside for externally rotating a water pipe joint (not shown) with a thread, and water flows out from the second water outlet 142 to the external water pipe joint. In this embodiment, an annular step surface 146 is formed on the inner side of the secondary pipe 14 near the second water outlet 142, and the filter assembly 20 is mounted to the second water outlet 142 through the step surface 146. In other examples, filter assembly 20 may be mounted by forming other structures, such as other protruding structures in secondary pipe 14 or protruding structures in primary pipe 12 to support filter assembly 20, or in some examples, fixing filter assembly 20 in primary or secondary pipes by bolts or the like.

Referring to FIG. 3, in particular, the filter assembly 20 is disposed within the secondary pipe 14 and extends inwardly of the primary pipe 12 such that the bottom thereof is disposed within the channel defined by the primary pipe 12. The filtering assembly 20 comprises in particular a support 21 and a filtering screen 22. The bracket 21 includes an upper end 211, a collar 212, a skeleton 213, and a bottom end cap 214. The upper end portion 211 is provided at an outer circumference thereof with a protruding ring 212, and the protruding ring 212 is mounted on the stepped surface 146 such that the filter assembly 20 is mounted at the second water outlet 142. The upper end 211 is a hollow cylinder, and a bottom end cap 214 having the same outer diameter as the upper end 211 is coaxially disposed with the upper end 211. The number of the skeletons 213 is plural, and the skeletons 213 are disposed in parallel, and both ends of the skeletons are respectively and vertically connected to the opposite end faces of the upper end part 211 and the bottom end cover 214. In this embodiment, the filter screen 22 is cylindrical and covers the frame 213, and both ends of the filter screen reach the end surfaces of the upper end 211 and the bottom end cap 214, respectively, and the bottom end cap 214 extends into the channel formed by the main pipe 12, so that the filter screen 22 is partially located in the main pipe 12.

Use the utility model discloses during the tee bend structure, put into auxiliary pipe 14 with filter assembly 20, then the water pipe head of screwing can fix filter assembly 20. After water flows in from the water inlet 122, the water continuously washes the part of the filter screen 22 located in the main pipe 12 and the part close to the main pipe 12, wherein a part of the water flows out from the second water outlet 142 after being filtered by the filter screen 22, and the other part of the water flows out from the first water outlet 124. Since the screen 22 does not completely cover the inner diameter of the main pipe 12, impurities in the water do not accumulate on the screen 22 and flow toward the first water outlet 124 along with the water. Therefore, the unfiltered water flowing out of the first water outlet 124 can be used for washing clothes, flushing toilets and the like with low requirements on water quality, and the filtered water flowing out of the second water outlet 142 can be used for occasions with high requirements on water quality, such as bathing, cooking and the like.

Example 2:

referring to fig. 4, compared with embodiment 1, the three-way structure further includes a fixing cap 16, and the sub-pipe 14 and the filter assembly 20 of embodiment 2 are different from embodiment 1.

Referring to fig. 4 and 5, in the present embodiment, the secondary pipe 14 is a square pipe, the fixing cover 16 is disposed on an end portion of the second water outlet 142 of the secondary pipe 14, a through hole is disposed in the middle of the fixing cover 16, a sidewall 162 with an external thread extends upward from the through hole for externally connecting a water pipe joint (not shown), and the fixing cover 16 is detachably and fixedly connected with an end of the secondary pipe 14 at the second water outlet 142. The support 21 is also in a square cylinder shape, and the outer edge of the support is attached to the inner edge of the auxiliary pipe 14, so that the support 21 is attached to the inner wall of the auxiliary pipe 14 and is installed in the auxiliary pipe 14. In other examples, the sub-pipe 14 and the holder 21 may have a cylindrical structure having other shapes.

In order to fix the filter assembly 20 in the secondary pipe 14, in the present embodiment, the bracket 21 is fixedly connected to the fixing cover 16 by welding or integral molding with the fixing cover 16, and is further fixedly connected to the secondary pipe 14. In other embodiments, the bracket 21 is fixedly connected to the secondary pipe 14 by screws.

A screen 22 is placed over the end of the support 21 adjacent the main pipe 12. In the present embodiment, the filter net 22 is disposed on the bottom surface of the bracket 21, and has a larger area and higher filtering efficiency than the cylindrical filter net in embodiment 1; a filter screen with smaller filter mesh can be selected, so that smaller impurities can be filtered, and the water quality is further improved; and the filter screen is on a parallel with the water flow direction in the main pipe, and the washing effect of the water flow on the filter screen is better, and impurities are not easy to accumulate.

Example 3:

please refer to fig. 6 and 7, which are schematic structural views of the toilet flush valve of the present embodiment. The toilet flushing valve comprises a water inlet assembly 30, a first water outlet assembly 40 and a second water outlet assembly 50, wherein the first water outlet assembly 40 and the second water outlet assembly 50 are identical in structure and are respectively connected to two sides of the water inlet assembly 30. In other examples, the toilet flush valve includes more than 2 outlet assemblies of the same configuration, each connected to the inlet assembly 30.

The water inlet assembly 30 includes a water inlet pipe 32 and a communication pipe 33 which are vertically and communicatively connected to each other, and both of the water inlet pipe 32 and the communication pipe 33 are T-shaped, and in other examples, the water inlet pipe 32 and the communication pipe 33 may be disposed at other inclination angles. The end of the inlet pipe 32 is provided with an externally threaded inlet 322 for externally connecting a water pipe connector (not shown). In the example of fig. 6-7, the sub-pipe 14 and the filter assembly 20 are provided at the connection of the communication pipe 33 and the inlet pipe 32. The water flows in from the water inlet 322, flows out from the filtered water outlet 35 after being filtered by the filter assembly 20 from the sub-pipe 14, and flows out from both ends of the communicating pipe 33 without being filtered. Preferably, the connection pipe 33 is further provided with a connector 34 on the wall opposite to the inlet pipe 32 for connecting a vacuum breaker (not shown) to prevent siphon backflow. The toilet flush valve of the present embodiment employs the three-way structure of embodiment 1, and in other examples, embodiment 2 or other forms of three-way structures may also be employed, and in some examples, the three-way structure may also be formed on the water inlet pipe 32, that is, the secondary pipe 14 and the filter assembly 20 are provided on the water inlet pipe 32.
