Referring to fig. 1-7, the present utility model provides a faucet with temperature switching function, which comprises: comprises a valve seat 1, a water outlet end cover 2, a manual valve and an inner cylinder 5. The valve seat 1, the water outlet end cover 2 and the inner cylinder 5 are made of stainless steel 316, so that the valve seat has preferable corrosion resistance and higher strength and toughness.
The valve seat 1 is used for being connected with an external water source, and the valve seat 1 is provided with a hot water interface C and a cold water interface D; the middle position of the top is provided with a hole for arranging the valve body 6 of the manual valve, and a plurality of water permeable holes 11 distributed in a ring shape are reserved on the top.
The water outlet end cover 2 is fixed on the valve seat 1, and an annular sealing ring 4 is arranged at the joint of the water outlet end cover and the valve seat to prevent water from seeping out from the joint. A water outlet channel B for discharging water is arranged on one side of the water outlet end cover 2, and a filter screen is arranged at a water outlet of the water outlet channel B; the filter screen is used for avoiding external impurities from entering the inside of the water outlet end cover 2. The water outlet channel B is lower than the water permeable holes 11 in horizontal height, so that water is conveniently discharged from the water outlet channel B along the water flow.
The manual valve comprises a valve body 6 for opening and closing water outlet and a valve rod 3 for moving the valve body 6; the valve rod 3 is fixedly connected with the valve body 6; the valve rod 3 is arranged at the top of the water outlet end cover 2; this facilitates the user to perform a rotational movement of the valve body 6 by manipulating the valve stem 3.
The valve body 6 is cylindrical, and the side surface is provided with a water inlet end 61 and a water outlet end 63, the water inlet end 61 and the water outlet end 63 are communicated through a communication chamber 62 inside the valve body 6, it is noted that the water inlet end 61 has 2 adjacent corners for distribution (see fig. 6), and the number of the water outlet ends 63 is not limited (see fig. 3-4).
The inner cylinder 5 is fixed inside the valve seat 1, the inner cylinder 5 is provided with a water inlet 51 (see fig. 7), the water inlet 51 is provided with 2 adjacent angles for distribution, and one water inlet is used for being communicated with the hot water interface C, and the other water inlet is communicated with the cold water interface D; the valve body 6 is installed in the inner cylinder 5, and water inlet is completed by corresponding the water inlet end 61 of the valve body 6 to the water inlet 51 (the water inlet 51 corresponding to the hot water interface C is hot water inlet, the water inlet 51 corresponding to the cold water interface D is cold water inlet, and meanwhile, the cold water and hot water inlet) or the valve body 6 is rotated to enable the water inlet end 61 of the valve body 6 to be staggered from the water inlet 51 for valve closing.
The top of the inner cylinder 5 is provided with a first chamber A; the water outlet end 63 of the valve body 6 is positioned in the first chamber A; the first chamber a is annular, and communicates with the water permeable hole 11, and water is discharged from the first chamber a to the water outlet end cap 2 through the water permeable hole 11.
A plurality of ball valve assemblies are annularly distributed at the top of the first chamber A; the ball valve assembly comprises a plurality of water permeable holes 11 annularly distributed on the inner barrel 5, ball valves 12 arranged on the water permeable holes 11, ball valve seats 13 for limiting the ball valves 12 and limiting rings 14. The ball valve seat 13 is annular and is provided with an inner inclined plane, and the ball valve seat 13 is fixedly arranged on the inner cylinder 5 and positioned at the outer edge of the water permeable hole 11, so that the ball valve 12 can stably fall on the water permeable hole 11 under the influence of the inclined plane. The inner diameter of the ball valve seat 13 is equal to that of the water permeable hole 11, and the outer diameter of the ball valve seat is larger than that of the ball valve 12, so that the ball valve seat 13 can not influence water outlet of the water permeable hole 11, and can limit the ball valve 12. The ball valve seat 13 is located at the bottom of the ball valve 12, so that when the valve body 6 is locked, the ball valve 12 can fall on the ball valve seat 13 due to gravity. The limiting ring 14 is fixedly connected with the valve body 6 through a plurality of cross bars, so that the limiting ring 14 is fixed. The limit ring 14 is positioned on top of the ball valve 12 such that when the water permeable hole 11 is drained, the ball valve 12 will be blocked by the limit ring 14 from moving upwards. The spacing between the limiting ring 14 and the ball valve seat 13 is smaller than the diameter of the ball valve 12, so that the ball valve 12 is prevented from being influenced by water flow and running out from a gap between the limiting ring 14 and the ball valve seat 13. The diameter of the ball valve 12 is larger than that of the water permeable hole 11, so that the ball valve 12 can be pressed against the water permeable hole 11 without falling (see fig. 6).
Working principle: by rotating the valve rod 3, the water inlet end 61 of the valve body 6 corresponds to the water inlet 51 of the inner barrel 5, water flows from the water inlet 51 to the water inlet end 61 to the communicating chamber 62 to the water outlet end 63, then water fills the first chamber A, when the first chamber A is full of water, more water will prop against the ball valve 12, the ball valve 12 floats, and then water flows out of the water outlet channel B.
