Embodiment
As shown in Figure 1-Figure 3, a kind of minute water, mixed water integral multifunctional ceramic valve core, comprise housing 1 and be arranged on the base 2 of its bottom.Base 2 is provided with hook 25, and housing 1 is provided with corresponding hook groove 11, and hook 25 fastens behind location with hooking groove 11, and base 2, with housing 1, relative movement cannot occur.And in order to keep stability between the two, on the circumference of base 2, also form two chimbs, with the groove fit on housing 1, further limit the degrees of freedom that turns between the two.
Support 7 bottoms are connected with driver plate 4, and support 7 bottom circumference are provided with the boss 71 to downward-extension, and driver plate 4 is provided with the breach 41 that coordinates with boss 71 and can slide along boss 71.Support 7 and driver plate 4 can move along support 7 by having realized boss 71 and being connected of breach 41 driver plate 4, and can with the co-rotational object of support 7.
Through hole 42 edges are provided with the block body 43 with groove, and this block body 43 is positioned at a side of breach 41, and on block body 43, card has the block 44 being positioned on breach 41, and block 44 ends are connected with spring 45, and the end of spring 45 is positioned on support 7 inwalls.Under the effect of spring 45 elastic force, block 44 front ends are stuck on the groove of block body 43, if not firmly stirring driving lever 3, cannot overcome the movement that resistance drives driver plate 4, have prevented the wrong open and close valve causing due to misoperation.
The below of driver plate 4 clamps and is fixed with ceramic moving plate 5, on base 2, clamp and be fixed with ceramic still 6, between ceramic still 6 and base 2, also have inner seal ring 9, for sealing between the two, base 2 bottoms are provided with exterior seal ring 10, for the isolating seal between base 2 entery and delivery ports.
In the present embodiment, the bottom of every flow channels coincide mutually with water intake shape separately, and top and bottom shape are all not identical.Wherein, first and second flow channels 61,62 is oppositely arranged, and is positioned at the both sides at ceramic still 6 centers, and top forms can be switched the complete totally enclosed sector of face 52; The first flow channels 61 is compared with the second flow channels 62, more departs from the center of ceramic still 6, and the distance between the inner arcuate midway point of sector of the inner arcuate midway point of its sector and the second flow channels 62 is less than the diameter in mixed flow chamber 51.
Third and fourth flow channels 63,64 is located between first and second flow channels 61,62, and is symmetrically distributed in the both sides at ceramic still 6 centers, and top forms can be switched the complete totally enclosed sector of face 52, and the shape of two sectors is basically identical; Distance between the inner circular arc of third and fourth flow channels 63,64 sectors is greater than the diameter in mixed flow chamber 51.
As shown in Figures 2 and 3, spool is in closed condition.Now the diverter surface 52 on ceramic moving plate 5 closes first and third, four flow channels 61,63,64 completely, and partially enclosed firmly the second flow channels 62, although cold water can flow to mixed flow chamber 51 from the second water intake 22, cannot flow out from any one water outlet.
As Figure 6-Figure 8, driving lever 3 is stirred left, driving lever 3 drives driver plate 4 and ceramic moving plate 5 to move to right, diverter surface 52 just closes the first flow channels 61 and the 4th flow channels 64, the second flow channels 62 and the 3rd flow channels 63 are communicated with mixed flow chamber 51, cold water enters from the second water intake 22, from the first water outlet 23, flows out to corresponding pipeline.If the angle that driving lever 3 is stirred is Y, Y is larger, the second water intake 22, the first water outlet 23 and mixed flow chamber 51 to be communicated with area larger, also larger by the flow of spool.
As shown in Figure 9 and Figure 10, again driving lever 3 is rotated counterclockwise to several angle, diverter surface 52 still closes the 4th flow channels 64, and partially enclosed firmly first and second flow channels 61,62, but two passes still has the connected part with mixed flow chamber 51, hot water and cold water enter mixed flow chamber 51 from first and second water intake 21,22 respectively and mix and become warm water so, by the first water outlet 23, are flowing out spools to corresponding pipeline.If the rotation angle of driving lever 3 is X, X is larger, and the second flow channels 62 reduces with the connected part in mixed flow chamber 51, and the first flow channels 61 increases with the connected part in mixed flow chamber 51, and the inflow of hot water will, more than cold water, flow out the water partial heat of the first water outlet 23 so.When going to maximum angle, the second flow channels 62 is switched face 52 and seals completely, and the first 23 of water outlets go out hot water.Now, if stir driving lever 3 adjustment angle Y, also can adjust the flow of hot water.
In like manner, as shown in Figure 11-Figure 13, driving lever 3 is stirred to the right, and driving lever 3 drives driver plate 4 and ceramic moving plate 5 to move to left, the first water outlet 23 not water outlets, and the second 24 of water outlets go out cold water, and the angle that driving lever 3 is stirred is larger, and the flow of cold water is larger.
As shown in Figure 14 and Figure 15, then driving lever 3 is clockwise rotated, the second water outlet 24 will go out warm water so, adjusts the angle that driving lever 3 rotates, and can change the water-exit temperature of the second water outlet 24.
The above is the preferred embodiment of the present invention, and it does not form limiting the scope of the invention.
