The above is the mutual relationship between the various components of the fluid switch device of the utility model using the magnetic control inner faucet. Secondly, the effect that the utility model can achieve is described as follows:

As shown in Fig. 2 and Fig. 3, the insert 313 of the driven magnetic ring 30 is first embedded in the positioning groove 41 of the driving block 40 during assembly, and the inner faucet set 2 can be formed. And the inner faucet set 2 is sleeved in the accommodation space 12 of the cylinder base 10; then, the main control magnetic ring 60 is sleeved in the concave ring 15 of the cylinder base 10; The leak-proof ring 70 is sleeved on the flange 53 of the output ring 50, and the output ring 50 is positioned on the bottom surface of the screw hole 21 of the fixing seat 20 by using two positioning pins 521, so that the hole 51 is aligned with the diversion groove 28 and the channel 26; finally, as long as the thread 16 of the cylinder seat 10 is inserted into the screw hole 21 of the fixed seat 20 and the rotating parts 14, 27 are clamped by hand tools Hold and do the screwing action, and make the protrusion 63 of the main control magnetic ring 60 extend in the limit groove 24 of the fixed seat 20, then the end surface of the bottom end of the cylinder seat 10 can be gradually pressed On the anti-leakage ring 70 , the flange 53 that promotes the output ring 50 is also pressed and positioned, so that the effect of anti-leakage can be obtained.

As shown in Figure 2 again, in order to facilitate the user's operation, a triangular mark 291, 292 is provided on the sides of the two ends of the limiting groove 24 of the fixed seat 20, and the sides of the two marks 291, 292 The words "ON" and "OFF" are printed respectively, and a mark 631 is also provided on the protrusion 63 of the main control magnetic ring 60, so that after the assembly is completed, if the mark 631 is aligned with the mark 291 [On alignment "ON"], it means that the perforation 42 of the drive block 40 is aligned with the hole 51 of the output ring 50, and is in an open state, allowing fluid to pass through (as shown in Figure 5); on the contrary Specifically, if the mark 631 is aligned with the mark 292 [to be aligned with "OFF"], it means that the perforation 42 of the driving block 40 and the hole 51 of the output ring 50 are staggered by 90 degrees and are in the closed state Instead, the fluid can be prevented from passing through (as shown in Figure 10).

In the open state shown in Figure 3, when viewed from the side sectional view (as shown in Figure 4), the through hole 311 of the driven magnetic ring 30 is aligned with the entrance 11 of the cylinder seat 10, and is aligned with the driven magnetic ring 30. The driving block 40 embedded with the magnetic ring 30 has two through holes 42 connected with the through hole 311 , and the two through holes 42 are aligned with the two holes 51 of the output ring 50 . In this way, when the fluid flows in from the input pipe 100, it can smoothly flow through the through hole 311, the two through holes 42, and the two holes 51, and finally be guided by the guide groove 28 of the fixing seat 20, which can Flows into the outlet pipe 200 via the channel 26 .

As shown in Fig. 5 and Fig. 6, when in the open state, the protrusion 63 of the main control magnetic ring 60 is located at one end of the limit groove 24 of the fixed base 20 provided with the "ON" mark 291, and the inside thereof The inner side 621 of each magnet 62 can attract the outer side 322 of the magnet 32 of the driven magnetic ring 30 in the opposite position. At this time, the driven magnetic ring 30 can be positioned in conjunction with the driving ring 40 , and the through hole 42 is aligned with the hole 51 .

Next, as shown in FIG. 7 and FIG. 8 , when the user rotates the main control magnetic ring 60 and moves the protrusion 63 of the main control magnetic ring 60 in the limiting groove 24 at an appropriate angle, The magnet 62 inside it will also rotate along with it, and the magnet 62, 32 is utilized to attract each other with different polarities, so that the driven magnetic ring 30 can rotate the same angle with the rotation of the main control magnetic ring 60, And the driving block 40 will be driven to rotate on the output ring 50, so that the matching amount of the through hole 42 and the hole 51 will be reduced, and with the rotation amount of the main control magnetic ring 60, the fluid can be controlled. How much flow flows out from the hole 51.

As shown in Figure 9, Figure 10 and Figure 11, when the protrusion 63 of the main control magnetic ring 60 has moved to the end of the limit groove 24 with the "OFF" mark 292, the driving block 40 It will be driven to rotate on the output ring 50 , and make the perforation 42 completely stagger from the hole 51 , so as to achieve the purpose of closing and preventing the fluid from flowing out from the output pipe 200 .

Therefore, it can be known from the above description that the protrusion 63 of the main control magnetic ring 60 can only move a stroke of about 90 degrees in the limiting groove 24 due to the limitation of the stroke of the limiting groove 24, and can Controlling the driven magnetic ring 30 and the driving block 40 also produces a 90-degree rotation, so that the 90-degree stroke change can achieve the effects of opening and closing the fluid and adjusting the fluid flow, and the operation is quite accurate. .

In addition, it is worth mentioning that the inner faucet group 2 of the present utility model is installed in the accommodation space 12 of the cylinder base 10 in a sealed state, and the setting of the leak-proof ring 70 is added, and the cylinder base 10, fixed The screw connection of the seat 20 is coated with adhesive, which can further ensure that the fluid inside the body 1 will not leak, and the feature of the utility model is that the main control ring magnet 60, which controls the opening and closing of the fluid, is located in the cylinder. Outside the seat 10, the inner faucet group 2 is magnetically controlled to rotate inside the barrel seat 10, which not only completely solves the problem of easy leakage of the previous fluid control switch, but also saves labor and is convenient in operation, and is a very practical The product.
