[0006] In addition, when adjusting the outlet water temperature, one end of the communication groove is connected to the cold water inlet hole and the hot water inlet hole at the same time. When the cold and hot water flow, there will be a great influence on each other, resulting in the flow of the valve core being limited. Especially the structure in the comparison file 1

Embodiment 1

[0056] Embodiment 1, a rotary water mixing valve core,

[0057] like figure 1 As shown, a rotary water mixing valve core includes a casing 9 and a base 10, and a rotary anti-scalding ceramic mixing valve plate assembly, a chuck 12 and a handle 11 are installed in the casing 9 and the base 10.

[0058] The rotary anti-scald ceramic water mixing valve plate assembly includes a movable valve plate 2 and a fixed valve plate 1, and the lower surface of the movable valve plate 2 and the upper surface of the fixed valve plate 1 are attached. The fixed valve plate 1 is provided with a cold water through hole 4 , a hot water through hole 3 and a water outlet through hole 5 penetrating the fixed valve plate 1 . A communication groove 6 is opened on the lower surface of the fixed valve plate 1 . The water outlet through hole 5 is located in the middle of the fixed valve plate 1 , and a part of the water outlet through hole 5 in the middle of the fixed valve plate 1 is always in communi...

Embodiment 2

[0067] Embodiment 2, a rotary water mixing valve core

[0068] The difference between the second embodiment and the first embodiment is the ceramic water mixing valve plate assembly. The ceramic water mixing valve plate assembly used in the second embodiment is as follows: Figure 12~14 As shown, a circular water outlet through hole 5 is provided in the middle of the fixed valve plate 1, and the water outlet through hole 5 may also be in an oval shape, a strip shape or other irregular shapes. The cold water through hole 4 and the hot water through hole 3 are respectively arranged on both sides of the water outlet through hole 5 . The cold water through hole 4 and the hot water through hole 3 can be circular as shown in the figure, or other shapes, such as oval, diamond, etc., can be used, so that the two ends of the cold water through hole 4 and the hot water through hole 3 are smaller, and the middle larger. The movable valve plate 2 is provided with a communication groove...

Embodiment 3

[0069] Embodiment 3, a kind of anti-scald ceramic water mixing valve core,

[0070] The difference between the third embodiment and the first embodiment is the ceramic valve plate assembly. The ceramic valve plate assembly in the third embodiment is as Figure 15~17shown. The water outlet through hole 5 is arranged in the middle of the fixed valve plate 1 in a circular shape, and the cold water through hole 4 and the hot water through hole 3 are respectively located on one side of the water outlet through hole 5 . The central angle occupied by the hot water through hole 3 on the fixed valve plate 1 is greater than the central angle occupied by the cold water through hole 4 on the fixed valve plate 1 . The movable valve plate 2 is provided with a communication groove 6 , the communication groove 6 is V-shaped, and the opening between the A end and the B end of the V-shaped communication groove 6 faces the edge of the movable valve plate 2 . The middle part of the communicati...

Abstract

The invention discloses a rotary anti-scald ceramic water mixing valve plate assembly and a rotary water mixing valve core. The valve plate assembly comprises a movable valve plate and a fixed valve plate. By redesigning the structures and positions of a cold water through hole, a hot water through hole, a water outlet through hole and a communication groove in each of the movable valve plate andthe fixed valve plate, when the movable valve plate is opened from a closed position, whether the movable valve plate rotates clockwise or counterclockwise, cold water flows out when the movable valveplate is opened, and no scalding accident occurs.

Description

technical field [0001] The invention relates to a valve core, in particular to a rotary anti-scald ceramic water mixing valve assembly and a rotary water mixing valve core. Background technique [0002] Existing ceramic water mixing valve cores can be divided into rotary type and pull type according to the control mode. The rotating ceramic water mixing spool only needs to turn the handle to make the spool in the closed state, the mixed water outlet state, the cold water outlet state or the hot water outlet state. The pull-type ceramic water mixing valve core handle can be pulled up and down, and can also be turned left and right. When pulled up and down, it controls the opening, closing and water output, and when it is turned left and right, it controls the water outlet temperature. [0003] When the existing ceramic water mixing valve core is switched from the closed state to the open state, it can realize both full hot water output (ie hot start) and full cold water outp...
