[0002] Some water outlet devices currently available on the market, such as shower heads, spray guns, faucets, etc., are generally provided with multiple water channels, and different water channels flow out different water sprays, thereby diversifying the functions of the water outlet devices. However, the switching mechanism for switching water channels on the current water outlet devices mostly adopts a ballpoint pen-type pressing switching mechanism, which cannot be reset to a pre-set common water outlet mode. After switching the water outlet mode, the next time the water outlet device is used, it needs to be switched and adjusted again to reset to the pre-set common water outlet mode, which is inconvenient for users.

[0011] The second valve core reset elastic member applies an elastic force to the second valve core in the direction of the third position. When the water inlet channel stops water, the second valve core moves to the third position under the action of the second valve core reset elastic member.

After the first button is released, the switching shaft moves to the sixth position under the action of water pressure, and the switching shaft and the first valve core move relative to each other through an idle stroke, so that the first valve core remains in the second position.

[0017] When the switching shaft is at the sixth position, when the first button is pressed in a direction perpendicular to the axis of the switching shaft, under the action of the inclined surface or the arc surface, the first button drives the switching shaft to slide in a second direction opposite to the first direction, and the switching shaft further drives the first valve core to slide from the second position to the first position.

[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] Please refer to Figures 1 to 6According to an embodiment of the present invention, a multi-waterway switching water outlet device with a reset function includes a main body 10, a first valve core 20, a second valve core 30, a switching assembly 40, a first valve core reset elastic member 50 and a second valve core reset elastic member 60.

[0048] The body 10 has a water inlet channel 14, a first water outlet 11, a second water outlet 12, a third water outlet 13, a first valve port 15, a second valve port 16, a third valve port 17 and a fourth valve port 18. The flow path between the water inlet channel 14, the first valve port 15, the third valve port 17 and the first water outlet 11 forms a first water path W1, that is, when the first valve port 15 and the third valve port 17 are both opened (when the first valve core 20 is in the first position and the second valve core 30 is in the third position), water flows through the first water path W1. At this time, Figure 3 As shown; the flow path between the water inlet channel 14, the second valve port 16 and the second water outlet 12 forms a second water path W2, that is, when the second valve port is opened (when the first valve core 20 is in the second position), the second water path W2 flows, at this time as Figure 4 As shown; the flow path between the water inlet channel 14, the first valve port 15, the fourth valve port 18 and the fourth water outlet forms a third water path W3, that is, when the first valve port 15 and the fourth valve port 187 are both opened (the first valve core 20 is in the first position and the second valve core 30 is in the fourth position), the third water path W3 flows, at this time Figure 5 shown.

[0049] The first valve core 20 is disposed in the body 10 , and the second valve core 30 moves between a first position for opening the first valve port 15 and blocking the second valve port 16 and a second position for blocking the first valve port 15 and opening the second valve port 16 .

[0050] The second valve core 30 is disposed in the body 10, and the second valve core 30 moves between a third position of opening the third valve port 17 and blocking the fourth valve port 18 and a fourth position of blocking the third valve port 17 and opening the fourth valve port 18. When the second valve core 30 is driven, the second valve core 30 moves to the fourth position and remains in the fourth position under the action of water pressure, and the second valve core 30 can link the first valve core 20 to move to the first position so that water can flow through the third waterway W3.

[0051] The switching assembly 40 is movably disposed on the main body 10 and cooperates with the first valve core 20 to drive the first valve core 20 to move between the first position and the second position. When the switching assembly 40 drives the first valve core 20 to move to the second position, the first valve core 20 remains in the second position under the action of water pressure.

[0052] The first valve core reset elastic member 50 applies elastic force to the first valve core 20 in the direction of the first position. When the water inlet channel 14 stops water, the first valve core 20 moves to the first position under the action of the first valve core reset elastic member 50, thereby resetting to the initial position. The first valve core reset elastic member 50 is preferably a compression spring.

[0053] The second valve core reset elastic member 60 applies elastic force to the second valve core 30 in the direction of the third position. When the water inlet channel 14 stops flowing, the second valve core 30 moves to the third position under the action of the second valve core reset elastic member 60, thereby resetting to the initial position. The second valve core reset elastic member 60 is preferably a compression spring.

[0054] In this embodiment, when the second valve core 30 is located at the third position, the movement of the first valve core 20 between the first position and the second position will not drive the second valve core 30. At this time, driving the first valve core 20 to move between the first position and the second position, that is, switching, allows water to flow through the first water channel W1 or the second water channel W2; when the second valve core 30 is maintained at the fourth position under the action of water pressure, the switching component 40 is driven, and the switching component 40 drives the first valve core 20 to move to the second position, thereby allowing water to flow through the second water channel W2, and the first valve core 20 drives the second valve core 30 to reset to the third position. In this way, when the switching component 40 is driven again to make the first valve core 20 move to the first position, since the second valve core 30 has been reset to the third position at this time, water is allowed to flow through the first water channel W1. That is to say, when the third water channel W3 is flowing through water, when the first valve core 20 is driven once, the second water channel W2 will be controlled to flow through water first, and when the first valve core 20 is driven again, the first water channel W1 will be controlled. In terms of the water flow order, the second water channel W2 is prior to the first water channel W1.

[0055] In this embodiment, the first valve core 20 and the second valve core 30 are linked together through the linkage shaft 70. The first valve core 20, the second valve core 30 and the linkage shaft 70 are coaxially arranged, and the first valve core 20, the second valve core 30 and the linkage shaft 70 slide on the coaxial line.

[0056] Specifically, the two ends of the linkage shaft 70 are respectively abutted against the first valve core 20 and the second valve core 30 to achieve linkage cooperation. When the second valve core 30 is in the third position, the sum of the transmission idle stroke between one end of the linkage shaft 70 and the first valve core 20 and the transmission idle stroke between the other end of the linkage shaft 70 and the second valve core 30 is L1, and the active stroke of the first valve core 20 in the first position and the second position is L2, and L1≥L2.

[0057] In this embodiment, a first button 80 and a first button reset elastic member 81 are also included. The switching assembly 40 includes a switching shaft 41, a first linkage block 42, a second linkage block 43, and a switching shaft reset elastic member 44. The first linkage block 42 is relatively fixed to the first button 80, and the second linkage block 43 is relatively fixed to the switching shaft 41. The first linkage block 42 and / or the second linkage block 43 are provided with inclined surfaces or arc surfaces on both sides. The switching shaft 41 is linked with the first valve core 20 and has a fifth position and a sixth position. A sliding cavity for sliding the switching shaft 41 is provided in the body 10, and a convex ring 411 is provided on the switching shaft 41 to seal and slide with the inner wall of the sliding cavity of the body 10.

[0058] Please refer to Figure 5 When the switch shaft 41 is in the fifth position, when the first button 80 is pressed in a direction perpendicular to the axis of the switch shaft 41, the first button 80 drives the switch shaft 41 to slide in the first direction under the action of the inclined surface or the arc surface, and the switch shaft 41 further drives the first valve core 20 to slide from the first position to the second position. After releasing the first button 80, the convex ring 411 on the switch shaft 41 moves to the sixth position under the action of water pressure, and the switch shaft 41 and the first valve core 20 move relative to each other by an idle stroke, so that the first valve core 20 remains in the second position.

[0059] Please refer to Figure 6 When the switch shaft 41 is in the sixth position, when the first button 80 is pressed in a direction perpendicular to the axis of the switch shaft 41, the first button 80 drives the switch shaft 41 to slide in a second direction opposite to the first direction under the action of the inclined surface or the arc surface, and the switch shaft 41 then drives the first valve core 20 to slide from the second position to the first position. After releasing the first button 80, the switch shaft 41 is reset to the fifth position under the action of the switch shaft reset elastic member 44. The elastic force of the switch shaft reset elastic member 44 is smaller than the first valve core reset elastic member 50, so that the first valve core 20 can be ensured to remain in the first position in the initial state.

[0060] Please refer to Figure 4 In this embodiment, the inclined surface includes a first inclined surface and a second inclined surface. The first inclined surface 421 is provided on both sides of the first linkage block 42, and the second inclined surface 431 is provided on both sides of the second linkage block 43. Figure 5 As shown, when the switch shaft 41 is in the fifth position, the first inclined surface 421 on one side of the first linkage block 42 cooperates with the second inclined surface 431 on one side of the second linkage block 43 to drive the switch shaft 41 to slide in the first direction. Figure 6 As shown, when the switch shaft 41 is at the sixth position, the first inclined surface 421 on the other side of the first linkage block 42 cooperates with the second inclined surface 431 on the other side of the second linkage block 43 to drive the switch shaft 41 to slide in the second direction.

[0061] In this embodiment, a second button 90 is further included, and the second button 90 cooperates with the second valve core 30. When the second button 90 is driven, the second button 90 drives the second valve core 30 to move from the third position to the fourth position, and the second valve core reset elastic member 60 pops up between the second button 90 and the main body 10. The second button 90 is reset under the action of the second valve core reset elastic member 60, thereby driving the second valve core 30 to reset from the fourth position to the third position.

[0062] In this embodiment, it also includes a shell 100 extending in the axial direction and sleeved outside the main body 10, a first button 80 is movably provided in the radial direction of the shell 100, and a second button 90 is movably provided at one axial end opening of the shell 100, the first button 80 drives the first valve core 20 to move through the switching component 40, and the second button 90 drives the second valve core 30 to move; the shell 100 is also provided with a first make way hole 110 and a second make way hole 120 in the radial direction, a water outlet 200 is provided at the first make way hole 110, the first water outlet 11 and the second water outlet 12 are connected to the corresponding water outlet holes on the water outlet nozzle 200, and the position of the second make way hole 120 corresponds to the third water outlet 13.

[0063] The working process of this embodiment is briefly described as follows:

[0064] Please refer to Figure 3 At this time, it is the default state of the water outlet device. The first valve core 20 is located in the first position under the action of the first valve core reset elastic member 50, the first valve core 20 opens the first valve port 15 and blocks the second valve port 16, and the second valve core 30 is located in the third position under the action of the second valve core reset elastic member 60, the second valve core 30 opens the third valve port 17 and blocks the fourth valve port 18. In this way, the first water path W1 formed by the flow path between the water inlet channel 14, the first valve port 15, the third valve port 17 and the first water outlet 11 passes water.

[0065] exist Figure 3 In the default water outlet state, the switching shaft 41 is located in the fifth position. The first button 80 is pressed, and the first button 80 drives the first linkage block 42, so that the first inclined surface 421 on the left side of the first linkage block 42 in the figure cooperates with the second inclined surface 431 on the right side of the second linkage block 43 in the figure, so that the second linkage block 43 and the switching shaft 41 slide to the left (first direction), and the switching shaft 41 then drives the first valve core 20 to slide to the left from the first position to the second position, and the first valve core 20 blocks the first valve port 15 and opens the second valve port 16, so that water can flow through the second waterway W2.

[0066] After the first valve core 20 slides to the second position, it remains in the second position under the action of water pressure, and the convex ring 411 on the switching shaft 41 slides rightward to the sixth position under the action of water pressure. Figure 4As shown, when the switch shaft 41 is in the sixth position, the first inclined surface 421 on the right side of the first linkage block 42 cooperates with the second inclined surface 431 on the left side of the second linkage block 43, so that pressing the first button 80 again can drive the switch shaft 41 to slide to the right (the second direction), thereby returning to the sixth position. Figure 3 In the default state, repeatedly pressing the first button 80 can cause the first valve core 20 to slide back and forth between the first position and the second position, thereby switching the first water path W1 or the second water path W2 to flow water.

[0067] Please refer to Figure 5 ,exist Figure 3 or Figure 4 In this state, the second button 90 is pressed, and the second button 90 drives the second valve core 30. The second valve core 30 moves to the fourth position and remains in the fourth position under the action of water pressure. In addition, the second valve core 30 links the first valve core 20 to the first position through the linkage shaft 70, thereby realizing water flow to the third water channel W3 and water cut-off of the first water channel W1 and the second water channel W2.

[0068] When water flows through the third water channel W3, the first button 80 is pressed to drive the switching component 40. The switching component 40 drives the first valve core 20 to move to the second position, thereby allowing water to flow through the second water channel W2, and the first valve core 20 drives the second valve core 30 to reset to the third position. When the switching component 40 is driven again to make the first valve core 20 move to the first position, the second valve core 30 has been reset to the third position at this time, thereby allowing water to flow through the first water channel W1. That is to say, when water flows through the third water channel W3, driving the first button 80 once will control the second water channel W2 to flow through water first, and driving the first button 80 again will control the first water channel W1. In terms of water flow order, the second water channel W2 precedes the first water channel W1.
