Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0029] Embodiment 1. As shown by Figures 1 to 4 the present embodiment of the present utility model provides a spool for adaptively switching the water outlet water path, which includes a spool housing 1 and a spool assembly 2 movably disposed in the spool housing 1.
[0030] The spool housing 1 is provided with a water passage 6 capable of sleeving the spool assembly 2, and a water inlet 3, a first water outlet 4 and a second water outlet 5 communicating with the water passage 6. Among them, the water inlet 3 is configured to be able to engage with a water source with a switch. The first water outlet 4 is configured to be able to engage with a first water outlet device. The second water outlet 5 is configured to be able to engage with a second water outlet device with a switch.
[0031] Preferably, in this embodiment, the first water outlet device is a rain shower. The second water outlet device is a handheld showerhead. In other embodiments, the first water outlet device and the second water outlet device can be other sanitary ware, such as a faucet, and the present utility model does not make specific limitations thereto.
[0032] The spool assembly 2 includes a sealing portion 21 located on the water outlet side of the first water outlet 4 and a water blocking portion 18 located on the water inlet side of the first water outlet 4. The sealing portion 21 and the water blocking portion 18 are respectively arranged on both sides of the water inlet 3. Wherein, the water blocking portion 18 is configured to be impacted by water flow when water flows out of the second water outlet 5 to generate a force along the water flow direction, so as to drive the sealing portion 21 to be in sealing contact with the first water outlet 4.
[0033] Specifically, the original pipeline is connected to the water inlet 3 and the first water outlet 4. The newly added waterway needs to be equipped with a waterway switch. When the waterway switch of the new waterway is not opened and the switch of the original waterway is opened, since the water flow cannot flow out from the second water outlet 5, under the action of water pressure, the sealing portion 21 is pushed open, so that the water flow flows from the first water outlet 4 to the original waterway. When the waterway switch of the new waterway is opened, the water flow flows to the new waterway (i.e., the second water outlet 5). At this time, the water flow impacts, thereby driving the sealing portion 21 to press down and sealingly disconnecting the first water outlet 4.
[0034] A spool of the utility model for adaptively switching the water outlet waterway can be used for the expansion of the existing pipeline. On the basis of retaining the original pipeline, a new pipeline is added. And when the newly added pipeline is opened, the original pipeline can be automatically disconnected, so as to realize the expansion of the existing pipeline, which has good practical significance.
[0035] As Figure 1 、 Figure 3 and Figure 4 shown, on the basis of the above embodiments, in an optional embodiment of the utility model, the spool assembly 2 includes a spool body 9 provided with the sealing portion 21 and the water blocking portion 18, and a first sealing ring 7 disposed on the sealing portion 21. Wherein, the first sealing ring 7 is used to seal the first water outlet 4. Specifically, the sealing ring can better fit the first water outlet 4 to seal the first water outlet 4. In other embodiments, other existing sealing contact structures can also be adopted, and the utility model does not make specific limitations thereto.
[0036] As Figure 1 、 Figure 3 and Figure 4 shown, on the basis of the above embodiments, in an optional embodiment of the utility model, the water blocking portion 18 is provided with a first water blocking blade 20 that can be impacted by water flow, and a first water passing hole 19 disposed on the first water blocking blade 20. Preferably, the water blocking portion 18 is provided with a second water blocking blade 13 that can be impacted by water flow, and a second water passing hole 14 disposed on the second water blocking blade 13. Wherein, the first water blocking blade 20 and the second water blocking blade 13 are arranged at intervals, and at least part of the second water blocking blade 13 is facing the first water passing hole 19.
[0037] Specifically, the water flow sequentially passes through the first water passing hole 19 and the second water passing hole 14, and then flows to the second water outlet 5. During the flowing process, it impacts the first water blocking blade 20 and the second water blocking blade 13, thereby driving the valve core to move downward, so that the sealing portion 21 is hermetically abutted against the first water outlet 4, thus disconnecting the original pipeline. Through the design of the double-layer water blocking blades, the area impacted by the water flow can be greatly increased, thereby generating a greater downward pressure to seal the first water outlet 4.
[0038] As Figure 4 shown, on the basis of the above embodiment, in an optional embodiment of the present utility model, the valve core assembly 2 includes a valve core attachment 16 joined to the valve core body 9. Wherein, the second water blocking blade 13 is arranged on the valve core attachment 16. Preferably, on the side of the first water blocking blade 20 away from the sealing portion 21, there extends an attachment groove 10 outward, and an attachment buckle 17 extends outward from the periphery of the attachment groove 10. The valve core attachment 16 can be embedded in the attachment groove 10 and is limited in the attachment groove 10 by the attachment buckle 17. The valve core assembly 2 further includes a second sealing ring 15 sleeved on the attachment buckle 17.
[0039] Specifically, arranging the second water blocking blade 13 on the valve core attachment 16 and constructing the valve core assembly 2 as a split structure can make the production and manufacturing simpler. In other embodiments, the two can be integrally designed, and the present utility model does not make specific limitations thereto. The second sealing ring 15 can increase the fastening force of the buckle and prevent the valve core attachment 16 from coming off under the impact of the water flow. In other embodiments, the valve core attachment 16 can be fixed by means such as welding, and the present utility model does not make specific limitations thereto either.
[0040] Preferably, the water blocking portion 18 further includes a third water blocking blade 12 extending from the second water blocking blade 13 towards the first water blocking blade 20. Wherein, at least a part of the third water blocking blade 12 is configured as an arc structure. The valve core assembly 2 further includes a third sealing ring 11 sleeved on the third water blocking blade 12. It should be noted that in other embodiments, the third water blocking blade 12 and the third sealing ring 11 may not be provided. Specifically, the third sealing ring 11 can keep the flow constant and increase the downward force of the piston.
[0041] As Figures 1 to 4As shown, on the basis of the above embodiments, in an alternative embodiment of the present utility model, the diameter of the water blocking portion 18 is greater than the diameter of the first water outlet 4, such that the axial projection area of the first water blocking blade 20 is greater than the axial projection area of the first water outlet 4, or the axial projection area of the first water blocking blade 20 + the axial projection area of the second water blocking blade 13 > the axial projection area of the first water outlet 4. Preferably, the axial projection area of the first water outlet hole < the axial projection area of the first water blocking blade 20 + the axial projection area of the second water blocking blade 13 + the axial projection area of the third water blocking blade 12.
[0042] As Figure 1 , Figure 3 and Figure 4 shown, on the basis of the above embodiments, in an alternative embodiment of the present utility model, the spool assembly 2 further includes a lip seal 8 sleeved on the water blocking portion 18. The opening of the lip seal 8 faces the first water outlet 4. The lip seal 8 is sealingly abutted against the side wall of the second water outlet 5.
[0043] Specifically, as Figure 1 shown, the opening of the lip seal 8 facing the first water outlet 4 can make the resistance when the spool assembly 2 moves downward less than the resistance when it moves upward, so that the spool assembly 2 can play a better role during operation. Preferably, the lip seal 8 is a U-shaped seal or a Y-shaped seal.
[0044] Embodiment 2: The present application further provides a valve for adaptively switching the water outlet waterway, which includes a valve housing 22 and a spool for adaptively switching the water outlet waterway as described in any section of Embodiment 1 disposed in the valve housing 22. Wherein, the valve housing 22 is provided with a water inlet interface 23 communicating with the water inlet 3, a first water outlet interface 24 and / or a second water outlet interface 25 communicating with the first water outlet 4, and a third water outlet interface 26 communicating with the second water outlet 5.
[0045] Specifically, the spool housing 1 of the spool and the valve housing 22 can be integrally provided or can be separately provided, and the present utility model does not make specific limitations on this.
[0046] Embodiment 3: The present application further provides a shower head for adaptively switching the water outlet waterway, which includes a valve for adaptively switching the water outlet waterway as described in any section of Embodiment 2 and a second water outlet device joined to the valve for adaptively switching the water outlet waterway.
