The patent includes a non-handheld first shower head and a handheld second shower head, and also includes a control device, which is installed on the first shower head and is used to control whether the first shower head discharges water; the second shower head and the first shower head have two matching states, one of which is that the second shower head is installed on the first shower head and drives the control device to operate to make the first shower head discharge water, and the other state is that the second shower head is separated from the first shower head, and the control device controls the first shower head to turn off the water.

[0003] However, the first shower head is always connected to the water source, and the second shower head is always structurally connected to the first shower head through a hose.

[0051] Please refer to Figures 1 to 4 , a first preferred embodiment of a waterway switching structure, the waterway switching structure comprises a first water outlet component 10, a second water outlet component 20 and a switching control mechanism.

[0052] The first water outlet component 10 is provided with a water inlet channel 12 and a first water outlet channel 11; the second water outlet component 20 is provided with a second water outlet channel 21, which is detachably assembled with the first water outlet component 10, and when the first water outlet component 10 is separated from the second water outlet component 20, the second water outlet component 20 is completely independent of the first water outlet component 10; the switching control mechanism is installed on the first water outlet component 10 and / or the second water outlet component 20; when the second water outlet component 20 is assembled with the first water outlet component 10, the switching control mechanism controls the water inlet channel 12 to be connected with the second water outlet channel 21, or the first water outlet channel 11 and the second water outlet channel 21 are connected with the water inlet channel 12 at the same time; when the second water outlet component 20 is separated from the first water outlet component 10, the water inlet channel 12 is only connected with the first water outlet channel 11.

[0053] In this embodiment, the first water outlet component 10 is further provided with a water passage 13 . When the first water outlet component 10 and the second water outlet component 20 are assembled, the switching control mechanism controls the water inlet channel 12 to be connected with the second water outlet channel 21 through the water passage 13 .

[0054] like Figure 2 As shown, the first water outlet component 10 includes a first upper body 14, a first inner body 15 and a first lower body 16, the first upper body 14 and the first lower body 16 are threadedly connected, the first inner body 15 is located in the first lower body 16 and is limited between the first upper body 14 and the first lower body 16. The first inner body 15 is provided with a switching cavity 151 with an opening, the switching cavity 151 and the water passage 13 are both arranged horizontally, the water inlet channel 12 is located below the switching cavity 151, the first water outlet channel 11 is located above the switching cavity 151, and the inlet of the first water outlet channel 11 and the inlet of the water passage 13 are both connected to the switching cavity 151. The water inlet channel 12 can be connected to the water source through a hose or a joint.

[0055] In this embodiment, Figure 4 As shown, the outlet of the water passage 13 is located on the outer side of the first water outlet component 10 .

[0056] The second water outlet component 20 is provided with a slot 22, and the first water outlet component 10 can be plugged into the slot 22; the second water outlet channel inlet 211 is connected to the slot 22. Figure 2 As shown, the slot 22 passes through the second water outlet component 20 from top to bottom, and the slot 22 has an opening 221; Figure 4 As shown, the second water outlet channel 21 is arranged horizontally. When the second water outlet component 20 is assembled with the first water outlet component 10, the water passage 13 and the second water outlet channel 21 are in the same plane and aligned, and the outlet of the water passage 13 can be connected to the inlet 211 of the second water outlet channel.

[0057] In this embodiment, Figure 4 As shown, a hollow sealing portion 212 is provided at the inlet 211 of the second water outlet channel.

[0058] The switching control mechanism includes a switching component and a triggering mechanism.

[0059] The trigger mechanism is installed in the second water outlet component 20. In this embodiment, the trigger mechanism includes a guide rail 30, which is fixed to the inner wall of the slot 22 and extends along the length direction of the slot 22.

[0060] In this embodiment, Figure 1 As shown, the guide rail 30 protrudes from the inner circumference of the slot 22. Preferably, a guide slope 31 is provided at the top of the guide rail 30 so that the switching shaft can slide smoothly along the guide rail 30.

[0061] The switching assembly is installed in the first water outlet component 10 , and the switching assembly is triggered by the trigger mechanism to switch the water inlet channel 12 to connect with the second water outlet channel 21 and / or the first water outlet channel 11 .

[0062] In this embodiment, the switching assembly is installed in the switching cavity 151 and includes a switching shaft 40 and a sealing gasket 41 fixed to the switching shaft 40; the switching shaft 40 is movably mounted on the first water outlet component 10 and the sealing gasket 41 moves between a position sealing the entrance of the first water outlet channel 11 and a position sealing the entrance of the water passage 13. When the second water outlet component 20 is assembled with the first water outlet component 10, the switching shaft 40 can drive the sealing gasket 41 to move to a position sealing the entrance of the first water outlet channel 11 under the push-pull action of the guide rail 30. The head end of the switching shaft 40 extends out of the opening of the switching cavity 151.

[0063] In this embodiment, the switching assembly also includes a reset elastic member 50, the two ends of which respectively press against the sealing gasket 41 and the switching cavity 151 of the first water outlet component 10. When the second water outlet component 20 is separated from the first water outlet component 10, the reset elastic member 50 drives the sealing gasket 41 to move to the position of the entrance of the sealing water channel 13 under its own elastic action.

[0064] The working principle of the waterway switching structure is:

[0065] like Figure 1 As shown, when the first water outlet component 10 is separated from the second water outlet component 20, the sealing gasket 41 seals the entrance of the water passage 13, the water inlet channel 12 is connected to the first water outlet channel 11, and water is discharged from the first water outlet channel 11; the second water outlet component 20 is not connected to the water inlet channel 12 or the water source by any waterway, and the second water outlet component 20 is not connected to the first water outlet component 10 by any structure. The second water outlet component 20 is an independent component and can be moved at will. It can be taken out for use when needed and can be directly removed when not needed, without affecting the water discharge of the first water outlet component 10; or, it can be switched and assembled with multiple first water outlet components 10, and the utilization rate is greatly improved;

[0066] like Figure 3 and Figure 4 As shown, the first water outlet component 10 is plugged into the slot 22. When the first water outlet component 10 is inserted into the slot 22 from top to bottom, the switching shaft 40 moves downward along the guide rail 30. When the switching shaft 40 moves downward, it moves toward the central axis of the switching shaft 40 under the top of the guide rail 30, driving the sealing gasket 41 to move synchronously until the sealing gasket 41 seals the entrance of the first water outlet channel 11. At this time, the first water outlet channel 11 does not discharge water, the water passage 13 is connected to the water inlet channel 12, and water discharges from the second water outlet channel 21. In this embodiment, the waterway switching is automatically completed after the second water outlet component 20 and the first water outlet component 10 are assembled.

[0067] Please refer to Figure 5, which is the second preferred embodiment of the water channel switching structure. The difference between this embodiment and the previous embodiment is that when the first water outlet component 10 is plugged into the slot 22, the sealing gasket 41 is located between the entrance of the first water outlet channel 11 and the entrance of the water passage 13, that is, at this time, the first water outlet channel 11 and the second water outlet channel 21 discharge water at the same time.

[0068] Please refer to Figures 6 to 9 , which is the third preferred embodiment of the waterway switching structure.

[0069] The difference between this embodiment and the previous embodiment is that:

[0070] In this embodiment, the guide rail 30 is movably mounted in the second water outlet component 20 and is provided with a clearance groove 32 and a top abutment surface 33. When the second water outlet component 20 is assembled with the first water outlet component 10, the movable guide rail 30 enables the switching shaft 40 to drive the sealing gasket 41 to move to a position that seals the entrance of the first water outlet channel 11 under the action of the top abutment surface 33 of the guide rail 30. Figure 5 As shown, the side surface of the guide rail 30 is provided with two groups of upper and lower clearance grooves 32 and top abutment surfaces 33, and each group of top abutment surfaces 33 is arranged adjacent to the clearance grooves 32 in front and back, and the top abutment surfaces 33 are planes. The clearance grooves 32 include an inclined front groove wall, a horizontal bottom groove wall, a vertical rear groove wall and a guide groove wall connected in sequence.

[0071] In this embodiment, a transmission member 60 is movably disposed in the second water outlet channel 21 , and the transmission member 60 is transmission-connected between the guide rail 30 and the switching shaft 40 .

[0072] In this embodiment, a transmission block 61 is provided on the outer periphery of the transmission member 60, and the transmission block 61 can be matched with the clearance groove 32 and the abutment surface 33 of the guide rail 30, and the transmission member 60 can abut against the switching shaft 40. Figure 5 As shown, the transmission member 60 is cylindrical, and a transmission rod 62 is provided at the center of the end of the transmission member 60, and the transmission rod 62 can be pressed against the switching shaft 40. The transmission block 61 is provided with two transmission blocks 61, which are symmetrically arranged up and down and correspond to the two groups of top abutting surfaces 33 and the clearance grooves 32 one by one, and the transmission block 61 can move freely between the top abutting surfaces 33 and the clearance grooves 32. When the transmission block 61 is pressed against the top abutting surface 33, the transmission member 60 drives the switching shaft 40 and the sealing gasket 41 to move until the sealing gasket 41 moves to the position of sealing the entrance of the first water outlet channel 11. When the transmission block 61 is matched with the clearance groove 32, the transmission member 60 is separated from the switching shaft 40, and the switching shaft 40 is reset under the action of the reset elastic member 50 to enable the sealing gasket 41 to move to the position of sealing the entrance of the water passage 13.

[0073] In this embodiment, the trigger mechanism further includes a button assembly, which is mounted on the second water outlet component 20 and is transmission-connected to the guide rail 30. Figure 5As shown, the button assembly includes a button 70, an upper gear shaft 71, a lower gear shaft 72 and a spring 73. The structural principle of the button assembly is similar to the structural principle of a ballpoint pen core. Pressing the button 70 drives the guide rail 30 to move forward and backward, so that the guide rail 30 has two states, one of which is: when the button 70 is pressed for the first time, the top abutment surface 33 of the guide rail 30 corresponds to the transmission block 61, and the other state is: when the button 70 is pressed again, the yield groove 32 of the guide rail corresponds to the transmission block 61.

[0074] In this embodiment, the user can select whether the second water outlet channel 21 discharges water when the second water outlet component 20 is assembled with the first water outlet component 10 as required. Figure 7 As shown, the button 70 is pressed to drive the guide rail 30 to move, the top abutting surface of the guide rail 30 corresponds to the transmission block 61, and the top abutting surface 33 abuts the transmission block 61 to drive the transmission member 60 to move, thereby driving the switching shaft 40 and the sealing gasket 41 to move until the sealing gasket 41 moves to the position of sealing the entrance of the first water outlet channel 11, the water inlet channel 12 is connected to the water passage 13, and water flows out of the second water outlet channel 21. The waterway switching structure of this embodiment has a situation where the sealing gasket 41 cannot completely seal the entrance of the first water outlet channel 11 due to the variation of the size of the parts. At this time, water will flow out of both the first water outlet channel 11 and the second water outlet channel 21. When the second water outlet component 20 is assembled with the first water outlet component 10, if the second water outlet channel 21 is not required to discharge water, the button 70 can be pressed to drive the guide rail 30 to move, and the clearance groove 32 of the guide rail 30 corresponds to the transmission block 61. At this time, the transmission block 61 is not subjected to the top resistance force, and the sealing gasket 41 is restored to the position of sealing the entrance of the water passage 13 under the action of the reset elastic member 50, and the transmission member 60 is synchronously reset under the action of the spring 90. Figure 8 shown.

[0075] Please refer to Figure 11 to Figure 12 , which is the fourth preferred embodiment of the waterway switching structure.

[0076] The difference between this embodiment and the second embodiment is that:

[0077] A reversing valve core 80 is disposed in the water inlet channel 12, and the reversing valve core 80 is provided with a water inlet 81, a first outlet 82, and a second outlet 83. The water inlet 81 is connected to the water inlet channel 12, the first outlet 82 is connected to the first water outlet channel 11, and the second outlet 83 corresponds to the water passage 13. The reversing valve core 80 is provided with a reversing valve shaft 84 and two reversing sealing pads 85, and the two reversing sealing pads 85 are respectively fixed to the two ends of the reversing valve shaft 84 and respectively matched with the first outlet 82 and the second outlet 83.

[0078] The trigger mechanism is the same as that of the second embodiment, and includes a button assembly and a guide rail 30 .

[0079] The switching assembly includes a switching shaft 40 and a sealing gasket 41 fixed to the switching shaft 40. The switching shaft 40 is movably mounted on the first water outlet component 10 and the sealing gasket 41 moves between a position sealing the entrance of the water passage 13 and a position opening the entrance of the water passage 13. When the second water outlet component 20 is assembled with the first water outlet component 40, the switching shaft 40 can drive the sealing gasket 41 to move to a position opening the entrance of the water passage 13 under the push-up action of the guide rail 30.

[0080] In this embodiment, when the sealing gasket 41 is in a position to open the entrance of the water passage 13, the second outlet 83 is connected to the water passage 13, and when the sealing gasket 40 is in a position to close the entrance of the water passage 13, the second outlet 83 is disconnected from the water passage 13.

[0081] Specifically, Fig.12 As shown, when the second water outlet component 20 is assembled with the first water outlet component 10, and the top abutment surface 33 of the guide rail 30 corresponds to the transmission block 61, the transmission member 60 drives the switching shaft 40 and the sealing gasket 41 to move until the sealing gasket 41 moves to a position where the entrance of the water passage 13 is opened. At this time, the pressure applied to the reversing sealing gasket 85 at the lower end of the reversing valve shaft 84 is greater than the pressure applied to the reversing sealing gasket 85 at the upper end of the reversing valve shaft 84. The reversing valve shaft 84 moves downward to allow the reversing sealing gasket 85 at the upper end to seal the first outlet 82, and the reversing sealing gasket 85 at the lower end contracts inward to open the second outlet 83. Water enters from the water inlet channel 12, flows through the water inlet 81, the second outlet 83, and the water passage 13, and then flows into the second water outlet channel 21, and water flows out from the second water outlet channel 21. When water flows out from the second water outlet channel 21 under the action of the reversing valve core 80, the first water outlet channel 11 always remains in a state of not discharging water.

[0082] When the second water outlet component 20 is separated from the first water outlet component 10, the sealing gasket 41 is restored to the position of sealing the entrance of the water passage 13 under the action of the reset elastic member 50, and the pressure applied to the reversing sealing gasket 85 at the upper end is greater than the pressure applied to the reversing sealing gasket 85 at the lower end, so that the reversing sealing gasket 85 at the lower end seals the second outlet 83, and the reversing sealing gasket 85 at the upper end opens the first outlet 82, and the water in the water inlet channel 12 flows through the water inlet 81 and the first outlet 82 into the first water outlet channel 11, and water flows out of the first water outlet channel 11.

[0083] Applying the switching method of the water channel switching structure described above, the second water outlet component 20 is assembled with the first water outlet component 10, and the switching control mechanism controls the water inlet channel 12 to be connected with the second water outlet channel 21, or the first water outlet channel 11 and the second water outlet channel 21 are connected with the water inlet channel 12 at the same time, and the second water outlet channel 21 discharges water, or the first water outlet channel 11 and the second water outlet channel 21 discharge water at the same time; the second water outlet component 20 is separated from the first water outlet component 10, the water inlet channel 12 is only connected with the first water outlet channel 11, and only the first water outlet channel 11 discharges water, and the second water outlet channel 21 does not discharge water, and the second water outlet component 20 can be separated from the first water outlet component 10 and moved arbitrarily.

[0085] In this embodiment, the first water outlet terminal 100 is a hand-held shower. As needed, the first water outlet terminal 100 can also be one of a top-spray shower, a shoulder-neck water shower, a kitchen shower, a kitchen faucet, a bathtub faucet and a spray gun, or one of the mother-and-child showers; the second water outlet terminal 200 is a shoulder-neck water shower. As needed, the second water outlet terminal can also be one of a hand-held shower, a top-spray shower, a kitchen shower, a kitchen faucet, a bathtub faucet and a spray gun, or another of the mother-and-child showers, but is not limited to this.

[0086] like Figures 14 to 16 , which is the second preferred embodiment of the kitchen and bathroom product. In this embodiment, the first water outlet terminal 100 is a sub-shower in a sub-shower, and the second water outlet terminal 200 is a sub-shower in a sub-shower. The waterway switching structure can adopt any one of the above four embodiments, or can also be as follows:

[0087] In this embodiment, the trigger mechanism is a push rod 110, and the switching component is a pilot valve core. The pilot valve core is installed in the water passage 13 and has a pilot valve stem 120. When the second water outlet component 20 is assembled with the first water outlet component 10, the pilot valve stem 120 can open the water passage 13 under the push action of the push rod 110. Fig.15As shown, the pilot valve core also includes a pilot valve seat 121, a pilot sealing gasket 122 and a pilot spring 123. The pilot valve seat 121 is fixedly connected to the entrance of the water passage 13 and is provided with a pilot back pressure chamber 124. The head end of the pilot valve stem 120 passes through the pilot back pressure chamber 124 and then extends out of the pilot valve seat 121. The pilot sealing gasket 122 is hollow and its inner periphery is fixedly connected to the outer periphery of the tail end of the pilot valve stem 120, and its outer periphery is fixedly connected to the inner wall of the entrance of the water passage 13. The pilot spring 123 presses between the inner wall of the water passage 13 and the pilot valve stem 120. When the second water outlet component 20 is aligned with the first water outlet component 20, the pilot valve stem 120 is pressed against the inner wall of the water passage 13. When the components 10 are assembled, the push rod 110 just presses against the pilot valve stem 120 to drive the pilot valve stem 120 to move along its central axis to open the pilot back pressure chamber 124. At this time, the pressure in the pilot back pressure chamber 124 is released, so that the pilot sealing gasket 123 opens the water passage 13. At this time, the water inlet channel 12 is connected with the water passage 13. A part of the water in the water inlet channel 12 flows through the water channel 13 and then enters the second water outlet channel 21. Another part of the water in the water inlet channel 12 flows out from the first water outlet channel 11. At this time, the first water outlet channel 11 and the second water outlet channel 21 discharge water at the same time.

[0088] In this embodiment, a water connection structure capable of moving under the action of water pressure is provided at the outlet of the water passage 13. The water connection structure comprises a hollow connecting pipe 130 and a hollow movable sealing pad 131. The inner periphery of the movable sealing pad 131 is fixedly sleeved on the outer periphery of the connecting pipe 130, and its outer periphery is fixedly connected to the inner wall of the water passage 13. The movable sealing pad 131 can drive the connecting pipe 130 to move at the outlet of the water passage 13 under the action of water pressure to extend into or move out of the second water outlet channel 21. Preferably, a hollow third sealing portion 140 and a spring 141 are provided at the entrance of the second water outlet channel 21. When there is water flow in the water passage 13, the pressures on both sides of the movable sealing pad 131 are different, and the water pressure is greater than the atmospheric pressure. At this time, if Fig.16 As shown, under the action of water pressure, the movable sealing gasket 131 is driven to move to the right and then drives the connecting pipe 130 to move to the right until the end of the connecting pipe 130 is pressed against the third sealing part 140. The third sealing part 140 is movable to reduce the pressure difference on the movable sealing gasket 131 and increase the service life of the movable sealing gasket 131.

[0089] The method of using the shower head is as follows: Fig.15 As shown, the sub-shower head and the main shower head are in a separated state, and only the first water outlet channel 11 is discharging water; Fig.16 As shown, when the sub-shower head is assembled with the main shower head, the first water outlet channel 11 is always connected with the water inlet channel 12, and the second water outlet channel 21 is connected with the water inlet channel 12 through the water passage 13. The first water outlet channel 11 and the second water outlet channel 21 discharge water at the same time, which can increase the water outlet area.

[0090] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
