[0030] With reference to the drawings, a switching device comprises a valve seat 10 with a water distribution cavity 11, the valve seat is provided with a first water outlet 14, a first water passage 12 and a second water passage 13 which can communicate with the water distribution cavity, the water flow of the water distribution cavity can flow out of the first water outlet through the first water passage, the valve seat is provided with a movable valve core 20, which can also be a plug, for controlling whether the two water passages are water or not, the valve core is provided with a first sealing part 21 and a second sealing part 22; the inner wall of the first water passage is formed with a first sealing surface 121 which can be sealed with the first sealing part, the inner wall of the second water passage is formed with a second sealing surface 131 which can be sealed with the second sealing part, the cross-sectional area S1 of the first sealing part is greater than the cross-sectional area S2 of the second sealing part; further comprising a first water passage 50, when the first sealing part cooperates with the first sealing surface, the water flow of the water distribution cavity can flow out of the first water outlet through the first water passage.
[0031] Preferably, the first water outlet is also connected with a water passing operation module 30, which has three states, namely small flow water passing (water pause), large flow water passing and water cut-off state. When the operation module is in the state of small flow water passing, the operation module forms a second water passing outlet 31 which can pass water. The water passing area S4 of the second water passing outlet is larger than the water passing area S3 of the first water passing outlet, so that the water flow can drive the valve core to move and enable the first sealing part to be unsealed from the first sealing surface. At this time, because of the difference in cross-sectional area, the water flow of the first water passing outlet cannot meet the requirement of the rear-end flow. In order to compensate for the water flow of the rear-end, the water flow will make the valve core move (a small displacement can be made from the sealing state), so that the first sealing part is slightly separated from the first sealing surface to form a water passing gap 122, which compensates for the difference in water passing area between S4 and S3, and prevents the water flow from unsealing the second sealing part from the second sealing surface after the first sealing part is sealed with the first sealing surface, so as to avoid the mis-switching situation. At the same time, the operation module can have two switching shafts 32 in use, the left one is used to switch between large flow water passing and small flow water passing, and the right one is used to realize water cut-off; in another use, the operation module has a combination of button control and knob control, the button is used to realize water cut-off, and the knob rotation is used to switch between large flow water passing and small flow water passing, or vice versa; in still another use, the operation module can be constructed to realize water cut-off and switch between large flow water passing and small flow water passing by knob rotation.
[0032] Further, the operation module also has a water cut-off state and a large flow water passing state; when the operation module is in the water cut-off state, the water flow can drive the valve core to move and unseal the second sealing part from the second sealing surface, at this time, the first sealing part is in sealing cooperation with the first sealing surface; when the operation module is in the large flow water passing state, the water flow can drive the valve core to move and unseal the first sealing part from the first sealing surface, and at the same time, the second sealing part is in sealing cooperation with the second sealing surface.
[0033] Still further, when the second sealing part is in sealing cooperation with the second sealing surface, the first sealing part can be in sealing cooperation with the first sealing surface, or the first sealing part can not be in sealing cooperation with the first sealing surface. In use, the two sealing cooperations cannot be unsealed at the same time, that is, the first water passing outlet and the second water passing outlet cannot pass water at the same time.
[0034] Preferably, the first water passing outlet can be arranged on the valve seat and / or the valve core.
[0035] In the embodiment one, the water outlet is arranged on the first sealing part, and a thimble 40 is inserted into the first water outlet, so that the scale remaining in the first water outlet can be automatically cleaned during use, and the water flow is ensured to be smooth; at this time, S3 is the minimum cross-sectional area of the water flow allowed by the first water outlet after deducting the space occupied by the thimble.
[0036] In the embodiment two, a water channel 16 is arranged in the valve seat, the first water outlet is arranged at the valve seat at the rear end of the first water passage, and the water distribution cavity can flow out from the first water outlet through the water channel and the first water outlet.
[0037] In a specific use, the first water outlet can be connected with a first water outlet device, and the second water passage can be connected with a second water outlet device; the first water outlet device can be a handheld shower, and the second water outlet device can be a top spray, and the two water outlet devices are not shown in the figure; the switching device in the utility model can also be integrated in the second water outlet device.
[0038] Further, the water flow of the first water outlet can flow out from the first water outlet device through an operation module, and the operation module can be integrated in the first water outlet device; the water flow in the water distribution cavity can keep connected with the first water outlet through the first water outlet.
[0039] The utility model more specifically discloses: a remote switching structure mainly includes: valve seat, is provided with first sealing surface and second sealing surface, all along valve seat axis arrangement, two sealing surfaces have a certain length on the axis, valve core is provided with first sealing part and second sealing part, can respectively with valve seat first sealing surface, second sealing surface sealing cooperation.When the valve core sealing part moves on the valve seat sealing surface, the sealing part and the sealing surface of the corresponding position are always in the sealed state. Still include with switching module cooperation's operation module. Among them: 1, sealing part cross-sectional area S1 > S2;2, flow cross-sectional area S3 < flow cross-sectional area S4;3, S3 flow cross-sectional area is less than 5 square millimeters. Valve seat two ends are fluidly connected with first water outlet device and second water outlet device, and the operation module is arranged in the process of being connected to the first water outlet device, and the operation module can switch three states: 1, large flow water; 2, small flow water;3, water cut-off (that is, no water).

The first sealing part and the first sealing surface are separated from the sealing cooperation, and the water flow of the water distribution cavity is connected to the first water outlet device.
[0041] During the movement of the valve core, the first sealing part and the second sealing part of the valve core and the valve seat can be in the intermediate state of sealing cooperation, and at this time, neither of the two water outlet devices can be out of water.
[0042] When the operation module is in the small flow water passing state, because S4>S3, the water flow through S3 is mostly discharged by S4, the valve core is not in the intermediate state, at this time, the water pressure on the first sealing part of the valve core is greater than the water pressure on the second sealing part, the valve core moves to the first sealing part direction, the first sealing part and the first sealing surface slightly separate from the sealing cooperation, and the water flow in the water distribution cavity slightly passes to the first water outlet device.
[0043] When the operation module is in the water cutting state, the switching device is in the second water passing opening water passing state, the water in the water distribution cavity is no longer in flow with the first water passing opening, under the communication of the first water passing opening, the water pressure on both sides of the valve seat near the first water outlet balances, and the water pressure on both sides of the first sealing part of the valve core offsets each other, at this time, only the second sealing part of the valve core has pressure, the valve core moves to the second sealing part direction under the water pressure on the second sealing part, the second sealing part and the second sealing surface separate from the sealing cooperation, the water flow in the water distribution cavity passes to the second water outlet device, at this time, the first water outlet device is not in water passing state.
