The mixing seat 40 is sleeved between the first valve seat 20 and the second valve seat 30 in a sealing way, and the central axis of the mixing seat is coincident with the central axis of the first valve seat 20 and the central axis of the second valve seat 30. The water mixing seat 40 is provided with a first connecting cavity 41 communicated with the first water inlet channel 11 and a second connecting cavity 42 communicated with the second water inlet channel 12, the assembling cavity 13 is positioned between the first connecting cavity 41 and the second connecting cavity 42, and the central axis of the assembling cavity 13 is vertical to the central axis of the water mixing seat 40. The first and second through holes 131 and 132 are located at left and right side walls of the fitting chamber 13, respectively.
The pressure balancing component is arranged in the assembly cavity 13 and comprises a movable body 100 which can move relative to the assembly cavity 13, and the first through hole 131 and the second through hole 132 can be communicated with the mixing cavity 14 through the movable body 100; when the water inlet pressure of one of the through holes 131, 132 is small, the movable body 100 is moved by the water pressure to increase the water inlet flow rate of the through hole and decrease the water inlet flow rate of the other through hole.
In this embodiment, the movable body 100 is provided with a first water passing cavity 110 and a second water passing cavity 120 which are independent from each other and are communicated with the mixing cavity 14, the periphery of the movable body 100 is provided with a first water passing hole 130 and a second water passing hole 140 which are communicated with the first water passing cavity 110 and the second water passing cavity 120, respectively, when the movable body 100 moves, the first water passing hole 130 is driven to align or stagger with the first through hole 131, and the second water passing hole 140 is driven to stagger or align with the second through hole 132.
In this embodiment, when the movable body 100 is moved, the stroke of the first water through hole 130 and the first through hole 131 being aligned or staggered is the same as the stroke of the second water through hole 140 and the second through hole 132 being aligned or staggered.
In this embodiment, a partition 150 is disposed in the movable body 100, the partition 150 divides the interior of the movable body 100 into the first water passing cavity 110 and the second water passing cavity 120, and the first water passing hole 130 and the second water passing hole 140 are symmetrically disposed relative to the partition. As shown in fig. 4, the first water passing hole 130 is positioned below the partition 150, and the second water passing hole 140 is positioned above the partition 150.
In this embodiment, the volume of the first water passing cavity 110 is the same as that of the second water passing cavity 120. In this embodiment, the pressure balancing assembly further comprises an outer body 200, the outer body 200 is fixedly attached in the assembly chamber 13 and is provided with a first side hole 210 and a second side hole 220 communicated with the first through hole 131 and the second through hole 132, respectively; the movable body 100 is movably sleeved in the outer body 200, and the movable body 100 drives the first water passing hole 130 to align or stagger with the first side hole 210 and the second water passing hole 140 to align or stagger with the second side hole 220 when moving.
In this embodiment, the first side hole 210 and the first water through hole 130 cannot be completely staggered, that is, the inlet water flow cannot be reduced to zero when the movable body 100 moves to reduce the inlet water flow of the first through hole 131, so that when only the first inlet channel 11 is opened and the second inlet channel 12 is closed, the first inlet channel 11 can also continuously feed water to make the water outlet connector 50 always have water flowing out. In this embodiment, the moving direction of the moving body 100 is perpendicular to the axial direction of the water mixing seat 40, that is, the moving direction of the moving body 100 is parallel to the central axis of the outer body 200 or the assembling cavity 13.
When the movable body 100 is moved to reduce the water inflow rate of the second through hole 132, the water inflow rate cannot be reduced to zero. That is, the second side hole 220 and the second water passing hole 140 cannot be completely staggered, and when only the second water inlet channel 12 is opened and the first water inlet channel 11 is closed, the second water inlet channel 12 can continuously feed water so that water flows out of the water outlet connector 50 all the time.
Taking the first water inlet channel 11 as a hot water inlet channel and the second water inlet channel 12 as a cold water inlet channel as an example, the working principle of the valve structure is as follows:
the hot water flows through the first connecting cavity 41 in the first water inlet channel 11, then sequentially passes through the first through hole 131, the first side hole 210 and the first water passing hole 130, then enters the first water passing cavity 110, and then flows into the mixing cavity 14 from the first water passing cavity 110; cold water flows through the second connecting cavity 42 in the second water inlet channel 12, then sequentially passes through the second through hole 132, the second side hole 220 and the second water passing hole 140, then enters the second water passing cavity 120, then flows into the mixing cavity 14 from the second water passing cavity 120, is mixed with hot water, and then flows out from the water outlet connector 50;
because the volumes of the first water passing cavity 110 and the second water passing cavity 120 are the same, and the areas of the upper and lower surfaces of the partition 150 are also the same, when the flow rate of hot water in the first water inlet channel 11 is reduced, the pressure of hot water in the first water passing cavity 110 is reduced, and the flow rate of cold water in the second water inlet channel 12 is not changed temporarily, the pressure applied to the upper end surface of the partition 150 is greater than the pressure applied to the lower end surface of the partition 150, so that the movable body 100 moves downwards under the action of water pressure, and the first water passing holes 130 are more aligned with the first side holes 210 during the downward movement of the movable body 100, so that the water passing area of the hot water channel is larger, so as to increase the inflow rate of hot water, meanwhile, the second water passing holes 140 are gradually staggered with the second side holes 220, so that the water passing area of the cold water channel is reduced, so as to reduce the inflow rate of cold water, so that the movable body 100 stops moving until the pressures of the first water passing cavity 110 and the second water passing cavity, and remains in a stable state.
Referring to fig. 6 to 8, a second preferred embodiment of a valve structure with pressure balance is shown, which is different from the first embodiment in that: the first water passing hole 130 is located behind the partition 150, and the second water passing hole 140 is located in front of the partition 150.
Referring to fig. 9 to 10, a third preferred embodiment of a valve structure with pressure equalization is shown, which differs from the first embodiment in that: the moving direction of the moving body 100 is parallel to the axial direction of the water mixing seat 40.
As shown in fig. 10, the first connecting cavity 41, the assembling cavity 13 and the second connecting cavity 42 are sequentially located at the left end, the middle and the right end of the water mixing base 40, and the central axes of the first connecting cavity 41, the assembling cavity 13 and the second connecting cavity 42 are coincident. The first and second through holes 131 and 132 are both disposed at the top end of the water mixing seat 40 and are both located between the first and second connection chambers 41 and 42, and the mixing chamber 14 is located between the lower end of the water mixing seat 40 and the second valve seat 30.
