[0044] The following further illustrates the detailed implementation manners of the present invention with reference to the accompanying drawings.

[0045] It is easy to understand that according to the technical solution of the present invention, without changing the essence of the present invention, there are various structural ways and implementation ways that can be mutually replaced by those of ordinary skill in the art. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the invention.

[0046] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined relative to the structures shown in the respective drawings. They are relative concepts and may accordingly change depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0047] The present application also provides a shower head water supply device 600, including: a shower head body 6 and a water path switching component 100.

[0048] The shower head body 6 includes a shower water chamber 60 and a bubbly water chamber 61. A bubbler 62 is arranged in the bubbly water chamber 61. The bubbler 62 mixes the water and air in the bubbly water chamber 61 so that the bubbly water chamber 61 sprays out bubbly water.

[0049] As Figures 1 to 5 shown, the shower head body in the present application provides un-mixed air shower water through the shower water chamber 60, and provides bubbly water with bubbles through the bubbler installed in the bubbly water chamber 61. The switching of the following water path switching assembly 100 realizes the water output of the shower water chamber 60 or the bubbly water chamber 61.

[0050] Among them, as Figure 6 shown, the water path switching assembly 100 includes a control pipe 1, a water inlet pipe 3, a first water outlet pipe 4 and a second water outlet pipe 5 that are all connected to the control pipe 1, and a control member. The control pipe 1 includes a first control end 10 and a second control end 11 arranged along the length direction, and a side opening 12 opened between the first control end 10 and the second control end 11. A valve core 2 that can be movably arranged between the first control end 10 and the second control end 11 is arranged in the control pipe 1.

[0051] When the valve core 2 moves to the first control end 10, the valve core 2 and the first control end 10 are on the same side of the side opening 12; the valve core 2 and the second control end 11 are on the same side of the side opening 12.

[0052] Please refer to Figure 2 , Figure 3 , Figure 9 , Figure 10 at the same time. When the valve core 2 and the first control end 10 are on the same side of the side opening 12, it means that when the valve core 2 moves to the first control end 10, the valve core 2 is entirely on the side of the inner wall of the side opening 12 close to the first control end 10, or the valve core 2 is partially located between the inner walls of the side opening 12. It meets the requirement that when the side opening 12 supplies water to the control pipe 1, the water pressure maintains the valve core 2 in contact with the first control end 10.

[0053] Please refer to Figure 1 , Figure 4 , Figure 6 , Figure 8 , Figure 11 and Figure 12 at the same time. When the valve core 2 and the second control end 11 are on the same side of the side opening 12, it means that when the valve core 2 moves to the second control end 11, the valve core 2 is entirely on the side of the inner wall of the side opening 12 close to the second control end 11, or the valve core 2 is partially located between the inner walls of the side opening 12. It meets the effect that when the side opening 12 supplies water to the control pipe 1, the valve core 2 maintains contact with the second control end 11.

[0054] The water inlet pipe 3 is connected between the side opening 12 and the shower water.

[0055] The first water outlet pipe 4 is connected between the first control end 10 and the flower sprinkler cavity 60. The first water outlet pipe 4 includes a first water outlet 40, so that after the water inlet pipe 3 stops supplying water to the first water outlet pipe 4, the valve core 2 has a tendency to rise under the action of the inertial force of the water flow in the first water outlet pipe 4. During a single shower water outlet cycle, at the moment when the water inlet pipe 3 stops supplying water to the control pipe 1 for the first time, the water flow flowing at the first water outlet 40 of the first water outlet pipe 4 pulls up the valve core 2 by inertial force, and the valve core 2 is limited at the first control end 10 under the upward pulling action of the inertial force, as Figure 2 and Figure 9 shown.

[0056] The second water outlet pipe 5 is connected between the second control end 11 and the bubble water cavity 61, as Figures 1 to 5 shown.

[0057] The control member is used to control the start and stop of the water flow entering the control pipe 1 from the water inlet pipe 3, so as to drive the valve core 2 to move between the first control end 10 and the second control end 11 of the control pipe 1, and control the water outlet of the flower sprinkler cavity 60 or the bubble water cavity 61.

[0058] The following introduces the single shower water outlet cycle of the shower water supply device 600. The control member controls the water inlet pipe 3 to supply water to the control pipe 1 for the first time according to the water supply time. At this time, the valve core 2 is limited at the second control end 11 under the action of water pressure, as Figure 1 and Figure 8 shown, so that the first water outlet 40 of the first water outlet pipe 4 discharges water to the flower sprinkler cavity 60, and the outlet of the flower sprinkler cavity 60 starts to spray water outwards. After the water inlet pipe 3 stops supplying water for the first time, the valve core 2 is pulled to abut against the first control end 10 under the action of the inertial pulling force of the water flow in the first water outlet pipe 4, as Figure 2 , Figure 9 shown. The controller controls the start and stop of the water supply of the water inlet pipe 3 to the control member 1, and supplies water for the second time when the valve core 2 abuts against the first control end 10, and the shower water discharges from the bubble water cavity 61 for spraying, as Figure 3 and Figure 10 shown. Water is supplied when the valve core moves to the same side of the side opening 12 as the valve core 2 and the second control end 11, and the shower water starts to spray outwards from the outlet of the flower sprinkler cavity 60, as Figure 1 and Figure 8 shown.

[0059] The shower water supply device 600 provided by the embodiment of the present application controls the start and stop of the water inlet from the water inlet pipe 3 to the control pipe 1 through a control member, so as to realize the water outlet of the shower water cavity 60 or the bubble water cavity 61, simplify the water supply pipeline structure of the shower head. The bubbler 62 arranged in the bubble water cavity 61 mixes the water flow and air in the bubble water cavity 61, realizes the spraying of bubble water in the bubble water cavity 61, realizes the flexible spraying of parts such as the head, improves the spraying effect, and increases the comfort of the shower. The above-mentioned water outlet process is controlled by the water path switching assembly 100, which simplifies the water outlet mode of the shower head and improves the convenience of use of the shower head.

[0060] As an optional embodiment, the first control end 10 is located above the second control end 11. As Figures 1 to 5 shown, in this embodiment, the first control end 10 is located above the second control end 11 along the direction of gravity. In the initial state, the ball valve 2 abuts against the second control end 11 under its own gravity. In a single shower water outlet cycle, at the moment when the first water supply from the water inlet pipe 3 to the control pipe 1 stops for the first time, the water flow flowing at the first water outlet 40 of the first water outlet pipe 4 pulls up the valve core 2 by inertia force. The valve core 2 moves to the first control end 10 under the upward pulling action of the inertia force against its own gravity, as Figure 4 shown. After the first water supply from the water inlet pipe 3 stops for a period of time, air begins to enter the first water outlet pipe 4, controlling to destroy the inertia force of the first water outlet pipe 4 on the valve core 2, and the ball valve 2 moves to abut against the second control end 11 under its own gravity.

[0061] As an optional embodiment, in a single shower water outlet cycle, the water inlet pipe 3 supplies water to the control pipe 1 for the first time, and the valve core 2 is limited at the second control end 11 under the action of water pressure, so that the first water outlet 40 of the first water outlet pipe 4 discharges water to make the shower water cavity 60 spray water, as Figure 1 and Figure 8 shown.

[0062] When the first water supply from the water inlet pipe 3 stops, the valve core 2 is pulled and moved to the first control end 10 under the inertial pulling force of the water flow in the first water outlet pipe 4. The height of the first water outlet 40 is lower than the height of the first control end 10, so that the valve core 2 is adsorbed and maintained at the first control end 10 under the gravity of the water flow in the first water outlet pipe 4, as Figure 2 and Figure 9 shown. Specifically, at the moment when the first water supply from the water inlet pipe 3 to the control pipe 1 stops, the water flow at the first water outlet 40 of the first water outlet pipe 4 pulls up the valve core 2 by inertia force, and the valve core 2 moves to the first control end 10 under the upward pulling action. At the same time, since the height of the first water outlet 40 is lower than that of the valve core 2, the inverted "U" - shaped structure of the first water outlet pipe 4 changes the gravity of the water into a suction force on the valve core 2 to maintain the valve core 2 limited at the position of the first control end 10 unchanged.

[0063] Before or at a preset water cut-off interval, the water inlet pipe 3 starts to supply water to the control pipe 1 for the second time according to the second water supply time, so as to limit the valve core 2 at the first control end 10 by water pressure before the valve core 2 drops. The second water outlet pipe 5 discharges water so that the bubble water chamber 61 sprays out bubble water, realizing the alternating water discharge between the flower watering chamber 60 and the bubble water chamber 61.

[0064] Alternatively, after a preset water cut-off interval, the water inlet pipe 3 starts to supply water to the control pipe 1 for the second time, so as to limit the valve core 2 at the second control end 11 by water pressure after the valve core 2 drops to the second control end 11. The first water outlet pipe 4 discharges water so that the flower watering chamber 60 sprays out water, realizing continuous water discharge of the flower watering chamber 60.

[0065] The preset water cut-off interval can be 0.5 s or 0.8 s, or can be set between 0.1 - 2.0 s. Specifically, it is the time length from the stop of the first water supply to the time before the air 8 gradually entering from the first water outlet 40 destroys the upward suction force of the water flow inertia force on the valve core 2, causing the valve core 2 to drop.

[0066] After the water inlet pipe 3 stops the second water supply, the valve core 2 moves to the second control end 11, as Figure 5 and Figure 11 shown. The time of the first water supply in this embodiment can be 3 s, or can be selected between 2 s - 10 s by controlling the solenoid valve, or the user operates the manual valve to control the duration of the first water supply according to the required water discharge time, so as to achieve a better spraying effect of the flower watering chamber 60.

[0067] At the moment when the water inlet pipe 3 stops the second water supply to the control pipe 1, the water flow in the second water outlet pipe 5 pulls down and limits the valve core 2 at the second control end 11 by inertia force. The water outlet of the second water outlet pipe 5 is lower than the valve core 2, turning the gravity of the water into the suction force on the valve core 2, and jointly maintaining the position of the valve core 2 unchanged with the gravity action of the valve core 2. At the same time, air 8 gradually enters from the side of the first water outlet pipe 4, and the air 8 destroys the inertia force of the water in the second water outlet pipe 5 on the valve core 2. The time of the second water supply in this embodiment can be 4 s, or can be selected between 2 s - 10 s by controlling the solenoid valve, or the user operates the manual valve to control the duration of the first water supply according to the required water discharge time, so as to achieve a better spraying effect of the bubble water chamber 61.

[0068] As an optional embodiment, a first step 13 for limiting the valve core 2 is provided at the first control end 10, and a second step 14 for limiting the valve core 2 is provided at the second control end 11. As Figures 6 to 12As shown, the first step 13 in the embodiment of the present application plays a role of abutting and limiting the valve core 2 at the first control end 10, and the second step 14 plays a role of abutting and limiting the valve core 2 at the second control end 11. When the valve core 2 moves to the first step 13, the side opening 12 is located below the valve core 2; when the valve core 2 moves to the second step 14, the side opening 12 is located above the valve core 2.

[0069] As an optional embodiment, there is a gap between the valve core 2 and the second step 14. In the embodiment of the present application, the gap left between the valve core 2 and the second step 14 can be used as a water discharge channel. A notch is provided on the second step 14. When the spherical valve core 2 abuts against the annular second step 14, the notch and the valve core 2 define the gap. After the second water supply ends, air 8 gradually enters from the side of the first water outlet pipe 4. The air 8 enters the second water outlet pipe 5 through the above-mentioned water discharge channel to destroy the attraction of the water flow in the second water outlet pipe 5 to the valve core 2. After a period of time, the water path switching assembly 100 returns to the initial state as shown in Figure 5 and Figure 12 shown. In the next single shower water outlet cycle, the above process is repeated starting from the first water supply.

[0070] As an optional embodiment, the gap between the valve core 2 and the inner wall of the control pipe 1 is L, and 0.1mm ≤ L ≤ 2mm. Setting the gap between 0.1mm and 2mm can not only ensure the smooth movement of the valve core 2 in the control pipe 1 driven by the water pressure, but also avoid the large gap between the valve core 2 and the inner wall of the control pipe 1 from affecting the driving effect of the water flow inertia on the valve core 2.

[0071] As an optional embodiment, a one-way control member 30 for allowing water flow to enter the control pipe 1 unidirectionally from the water inlet pipe 3 is provided in the water inlet pipe 3. The one-way control member 30 in the embodiment of the present application is used to isolate the water inlet pipe 3 and the control pipe 1, and at the same time achieve the effect of unidirectionally controlling the water flow to enter the control pipe 1 from the water inlet pipe 3. The one-way control member 30 in the embodiment of the present application can be a one-way valve or a check valve.

[0072] As an optional embodiment, one end of the water inlet pipe 3 is provided with a connecting elbow 31. The connecting elbow 31 is connected to the side opening 12. The connecting elbow 31 is horizontally arranged or inclined downward in the direction of the side opening 12. The one-way control member 30 is arranged in the connecting elbow 31. In the embodiment of the present application, the connecting elbow 31 provides a receiving space for the one-way control member 30. At the same time, the connecting elbow 31 is horizontally arranged or inclined downward in the direction of the side opening 12, which is beneficial to avoiding water flow from gathering at the connection between the connecting elbow 31 and the control pipe 1 and being unable to be discharged in time.

[0073] As an optional embodiment, the control member includes a control switch 71. The shower water is pressurized water, and the control switch 71 is provided on the water inlet pipe 3 or the water supply device of the pressurized water to control the water outlet of the sprinkler water chamber 60 or the bubble water chamber 61 by controlling the opening and closing of the control switch 71. The control switch 71 in the embodiment of the present application can be either an electromagnetic switch, and the controller controls the opening or closing of the control switch 71 according to a preset time; or it can be a manual switch, and the user controls the opening or closing of the control switch 71.

[0074] As an optional embodiment, the water supply device is a shower column 7 or a shower pipe, and a control seat 70 is provided on the water supply device, and the control switch 71 is located on the control seat. As Figure 13 shown, the control switch in the embodiment of the present application is in the shape of a button. During a single shower water outlet cycle, when the button is pressed for the first time, the sprinkler water chamber 60 discharges water; when the button is pressed for the second time, the bubble water chamber 61 discharges water; when the button is pressed for the third time before or at a preset water stop interval, the bubble water chamber 61 discharges water, or when the button is pressed for the third time after the preset water stop interval, the sprinkler water chamber 60 discharges water; after the button is pressed for the fourth time, the single shower water outlet cycle ends, and the shower water supply device stops supplying water.

[0075] The present application also provides a water outlet method for a shower water supply device to control the water outlet of the shower water supply device 600 in the above embodiments. As Figure 14 shown, it includes the following steps:

[0076] S1: The control member is used to control the start and stop of the water inlet pipe 3 to supply water to the control member 1 to control the water outlet of the sprinkler water chamber 60 or the bubble water chamber 61.

[0077] The control member controls the water inlet pipe 3 to supply water to the control pipe 1 for the first time according to the water supply time. At this time, the valve core 2 is limited at the second control end 11 under the action of water pressure. As Figure 1 and Figure 8 shown, so that the first water outlet 40 of the first water outlet pipe 4 discharges water to the sprinkler water chamber 60, and the outlet of the sprinkler water chamber 60 starts to spray water outwards. After the water inlet pipe 3 stops supplying water for the first time, the valve core 2 is pulled by the inertial pulling force of the water flow in the first water outlet pipe 4 to abut against the first control end 10. As Figure 2 、 Figure 9 shown. The controller controls the start and stop of the water inlet pipe 3 to supply water to the control member 1, and supplies water for the second time when the valve core 2 abuts against the first control end 10, and the shower water discharges and sprays from the bubble water chamber 61. As Figure 3 and Figure 10 shown. When the valve core moves to the same side as the valve core 2 and the second control end 11 at the side opening 12, water is supplied, and the shower water starts to spray outwards from the outlet of the sprinkler water chamber 60.Figure 1 and Figure 8 as shown

[0078] As an alternative embodiment, as Figure 15 shown, the following steps are further included

[0079] S10: Set the first control end 10 above the second control end 11. The first control end 10 is above the second control end 11 along the direction of gravity. In the initial state, the ball valve 2 abuts against the second control end 11 under its own gravity

[0080] S11: The control member controls the water inlet pipe 3 to supply water to the control pipe 1 for the first time. The valve element 2 is limited at the second control end 11 under the action of water pressure. At this time, the shower water passes through the water inlet pipe 3, the control pipe 1, and the first water outlet pipe 4 so that the sprinkler water cavity 60 sprays water

[0081] S12: The control member controls the water inlet pipe 3 to stop the first water supply. The valve element 2 is pulled up and moved to abut against the first control end 10 under the action of the inertial pulling force of the water flow in the first water outlet pipe 4. The height of the first water outlet 40 is lower than the height of the first control end 10, so that the valve element 2 is adsorbed and maintained at the first control end 10 under the action of the gravity of the water flow in the first water outlet pipe 4, as Figure 2 and Figure 9 shown. Specifically, at the moment when the water inlet pipe 3 stops supplying water to the control pipe 1 for the first time, the water flow at the first water outlet 40 of the first water outlet pipe 4 pulls up the valve element 2 by inertia, and the valve element 2 moves to the first control end 10 under the pulling action. At the same time, since the height of the first water outlet 40 is lower than that of the valve element 2, the inverted "U" - shaped structure of the first water outlet pipe 4 changes the gravity of the water into a suction force on the valve element 2 to maintain the valve element 2 limited at the position of the first control end 10 unchanged

[0082] S13: The control member controls the water inlet pipe 3 to start the second water supply to the control pipe 1 according to the second water supply time before or at a preset water cut-off interval, so as to limit the valve core 2 at the first control end 10 by water pressure before the valve core 2 drops, and the second water outlet pipe 5 discharges water to make the bubble water chamber 61 spray bubble water; or, the control member controls the water inlet pipe 3 to start the second water supply to the control pipe 1 after an interval of the preset water cut-off interval, so as to limit the valve core 2 at the second control end 11 by water pressure after the valve core 2 drops to the second control end 11, and the first water outlet pipe 4 discharges water to make the sprinkler water chamber 60 spray water. The preset water cut-off interval can be 0.5 s or 0.8 s, or can be set between 0.1 - 2.0 s, specifically, it is the time length from the stop of the first water supply to the time when the valve core 2 drops due to the air 8 gradually entering from the first water outlet 40 and destroying the upward suction force of the water flow inertia on the valve core 2.

[0083] After the second water supply of the water inlet pipe 3 stops, the valve core 2 moves to the second control end 11, as Figure 5 and Figure 11 shown. The first water supply time in this embodiment can be 3 s, or can be selected between 2 s - 10 s to achieve a better spraying effect of the sprinkler water chamber 60.

[0084] According to needs, the above technical solutions can be combined to achieve the best technical effect.

[0085] The above are only the principles and preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, based on the principle of the present invention, several other variations can also be made, which should also be regarded as the protection scope of the present invention.
