The present application also provides a shower water supply apparatus 600, comprising: the shower body 6 and the waterway switching assembly 100.

The shower body 6 comprises a shower water cavity 60 and a bubble water cavity 61, wherein a bubbler 62 is arranged in the bubble water cavity 61, and the bubbler 62 mixes water and air in the bubble water cavity 61 so that the bubble water cavity 61 sprays out bubble water.

As shown in fig. 1 to 5, the shower body of the present application provides shower water with unmixed air through the shower water chamber 60 and bubble water with bubbles through the installation of a bubbler in the bubble water chamber 61. The switching of the waterway switching assembly 100 as follows achieves the discharge of either the shower chamber 60 or the bubble water chamber 61.

As shown in fig. 6, the waterway switching assembly 100 includes a control tube 1, a water inlet tube 3, a first water outlet tube 4, a second water outlet tube 5, and a control member, all of which are connected to the control tube 1. The control tube 1 comprises a first control end 10, a second control end 11 and a side opening 12 arranged between the first control end 10 and the second control end 11 in a longitudinal direction. A valve spool 2 is arranged in the control tube 1 movably between a first control end 10 and a second control end 11.

When the valve core 2 moves to the first control end 10, the valve core 2 and the first control end 10 are positioned on the same side of the side opening 12; the spool 2 is located on the same side of the side opening 12 as the second control end 11.

Referring to fig. 2, 3, 9 and 10, the fact that the valve core 2 is located on the same side of the side opening 12 as the first control end 10 means that when the valve core 2 moves to the first control end 10, the valve core 2 is located on one side of the side opening 12 near the inner wall of the first control end 10, or the valve core 2 is located partially between the inner walls of the side opening 12. The requirement that the water pressure maintains the valve spool 2 in abutment against the first control end 10 when the side opening 12 supplies water to the control pipe 1 is satisfied.

Referring to fig. 1, 4, 6, 8, 11 and 12, the fact that the spool 2 and the second control end 11 are located on the same side of the side opening 12 means that when the spool 2 moves to the second control end 11, the spool 2 is located on one side of the side opening 12 near the inner wall of the second control end 11, or the spool 2 is located partially between the inner walls of the side opening 12. The effect of maintaining the valve spool 2 in abutment against the second control end 11 when the side opening 12 supplies water to the control pipe 1 is satisfied.

The inlet pipe 3 communicates between the side opening 12 and the shower water.

The first water outlet pipe 4 is communicated between the first control end 10 and the shower water cavity 60, and the first water outlet pipe 4 comprises 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 rising trend under the action of the inertia force of the water flow in the first water outlet pipe 4. In 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 flowing 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 is limited at the first control end 10 against self gravity under the action of the pulling-up of the inertia force, as shown in fig. 2 and 9.

The second water outlet pipe 5 is communicated between the second control end 11 and the bubble water chamber 61 as shown in fig. 1 to 5.

The control piece is used for controlling the start and stop of 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 the water outlet of the shower water cavity 60 or the bubble water cavity 61 is controlled.

The single shower outlet period of the shower water supply 600 is described below. The control piece controls the water inlet pipe 3 to supply water to the control pipe 1 for the first time according to the water supply time, and at the moment, the valve core 2 is limited at the second control end 11 under the action of water pressure, as shown in fig. 1 and 8, so that the first water outlet 40 of the first water outlet pipe 4 is enabled to discharge water to the shower water cavity 60, and the outlet of the shower water 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 inertial pulling force of water flow in the first water outlet pipe 4, as shown in fig. 2 and 9. The controller controls the start and stop of the water supply of the water inlet pipe 3 to the control pipe 1, the water is supplied for the second time when the valve core 2 is abutted against the first control end 10, and the shower water is sprayed from the bubble water cavity 61, as shown in fig. 3 and 10. 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, water is supplied, and shower water is sprayed outwards from the outlet of the shower water cavity 60, as shown in fig. 1 and 8.

According to the shower water supply device 600 provided by the embodiment of the application, the control part is used for controlling the water inlet pipe 3 to start and stop water inflow to the control pipe 1, so that water outflow of the shower water cavity 60 or the bubble water cavity 61 is realized, the water supply pipeline structure of the shower is simplified, wherein the bubbler 62 arranged in the bubble water cavity 61 mixes water flow and air in the bubble water cavity 61, the bubble water cavity 61 sprays bubble water, flexible spraying on the parts such as the head part is realized, the spraying effect is improved, and the comfort level of shower is increased. The water outlet process is controlled by the waterway switching assembly 100, so that the water outlet mode of the shower head is simplified, and the using convenience of the shower head is improved.

As an alternative embodiment, the first control terminal 10 is located above the second control terminal 11. As shown in fig. 1 to 5, in the present embodiment, the first control end 10 is located above the second control end 11 in the gravitational direction. In the initial state, the ball valve 2 is abutted against the second control end 11 under the action of self gravity. In 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 flowing 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 against self gravity under the upward pulling action of the inertia force, as shown in fig. 4. After the water inlet pipe 3 stops supplying water for a period of time for the first time, air starts to enter the first water outlet pipe 4, the inertia force of the first water outlet pipe 4 to the valve core 2 is controlled to be destroyed, and the ball valve 2 moves to be abutted against the second control end 11 under the action of self gravity.

As an alternative embodiment, in a single shower water outlet period, the water inlet pipe 3 supplies water to the control pipe 1 for the first time, 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 is used for discharging water, and the shower water cavity 60 is used for spraying water, as shown in fig. 1 and 8.

When the water inlet pipe 3 stops supplying water for the first time, the valve core 2 is pulled up to move to the first control end 10 under the action of inertial tension of the water flow in the first water outlet pipe 4, and the height of the first water outlet 40 is lower than that of the first control end 10, so that the valve core 2 is adsorbed and maintained at the first control end 10 under the action of gravity of the water flow in the first water outlet pipe 4, as shown in fig. 2 and 9. 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 core 2 through inertia force, and the valve core 2 moves to the first control end 10 under the action of the upward pulling. Meanwhile, as 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 water into the suction force to the valve core 2 so as to maintain the position of the valve core 2 limited at the first control end 10 unchanged.

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 before the preset water cut-off interval or when the preset water cut-off interval is set, so that the valve core 2 is limited at the first control end 10 before the valve core 2 falls down by water pressure, and the second water outlet pipe 5 discharges water so that the bubble water cavity 61 sprays out air bubble water, and alternate water discharge between the shower water cavity 60 and the bubble water cavity 61 is realized.

Or after the water inlet pipe 3 is separated by a preset water stopping interval, the water starts to be supplied to the control pipe 1 for the second time, so that the valve core 2 is limited at the second control end 11 through water pressure after the valve core 2 falls to the second control end 11, and the first water outlet pipe 4 discharges water so that the shower water cavity 60 sprays water, and continuous water discharge of the shower water cavity 60 is realized.

The preset water cut-off interval may be 0.5s or 0.8s, or may be set between 0.1 and 2.0s, specifically, the time period from when the first water supply is stopped to when the air 8 gradually entering from the first water outlet 40 breaks the upward suction force of the water flow inertial force on the valve core 2 to cause the valve core 2 to fall.

After the water inlet pipe 3 stops the second water supply, the valve cartridge 2 moves to the second control end 11 as shown in fig. 5 and 11. The time of the first water supply in this embodiment may be 3s, or may be controlled by an electromagnetic valve to select between 2s and 10s, or the user may operate a mechanical valve to control the duration of the first water supply according to the required water outlet time, so as to achieve a better spraying effect of the shower cavity 60.

At the moment when the water inlet pipe 3 stops supplying water to the control pipe 1 for the second time, the water flow in the second water outlet pipe 5 pulls down the valve core 2 to be limited at the second control end 11 through inertia force. The water outlet of the second water outlet pipe 5 is lower than the valve core 2, so that the gravity of water is changed into the suction force to the valve core 2, and the position of the valve core 2 is kept unchanged together with the gravity action of the valve core 2. Simultaneously, air 8 gradually enters from the side of the first water outlet pipe 4, and the air 8 damages the inertia force of water in the second water outlet pipe 5 to the valve core 2. The second water supply time in this embodiment may be 4s, or may be controlled by an electromagnetic valve to select between 2s-10s, or the user may operate a mechanical valve to control the duration of the first water supply according to the required water outlet time, so as to achieve a better spraying effect of the bubble water chamber 61.

As an alternative embodiment, the first control end 10 is provided with a first step 13 for limiting the valve spool 2, and the second control end 11 is provided with a second step 14 for limiting the valve spool 2. As shown in fig. 6 to 12, the first step 13 in the embodiment of the present application plays a role of abutment limit on the valve core 2 at the first control end 10, and the second step 14 plays a role of abutment limit on 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 positioned below the valve core 2; when the spool 2 moves to the second land 14, the side opening 12 is located above the spool 2.

As an alternative embodiment, there is a gap between the spool 2 and the second land 14. In the embodiment of the application, the gap reserved between the valve core 2 and the second step 14 can be used as a water drainage channel. A recess is provided in the second step 14, which recess delimits a gap with the valve element 2 when the spherical valve element 2 is in contact with the annular second step 14. After the second water supply is finished, air 8 gradually enters from the side of the first water outlet pipe 4, and the air 8 enters the second water outlet pipe 5 through the water discharging channel to destroy the attraction of water flow in the second water outlet pipe 5 to the valve core 2. After a period of time, waterway switching assembly 100 returns to the initial state shown in fig. 5 and 12. The next shower water outlet period is repeated from the first water supply.

As an alternative embodiment, the clearance between the valve core 2 and the inner wall of the control pipe 1 is L, and L is more than or equal to 0.1mm and less than or equal to 2mm. The gap is arranged between 0.1mm and 2mm, so that the valve core 2 can smoothly move in the control pipe 1 under the drive of water pressure, and the phenomenon that the gap between the valve core 2 and the inner wall of the control pipe 1 greatly influences the driving effect of water flow inertia on the valve core 2 is avoided.

As an alternative embodiment, a unidirectional control 30 is provided in the inlet pipe 3 for unidirectional flow of water from the inlet pipe 3 into the control pipe 1. The unidirectional control member 30 in the embodiment of the application is used for isolating the water inlet pipe 3 from the control pipe 1 and simultaneously achieving the effect of unidirectional control of the water flow from the water inlet pipe 3 into the control pipe 1. The one-way control 30 in embodiments of the present application may be a one-way valve or a check valve.

As an alternative embodiment, the water inlet pipe 3 is provided at one end with a connecting bend 31, the connecting bend 31 being connected at the side opening 12, the connecting bend 31 being arranged horizontally or inclined downwards in the direction of the side opening 12, the unidirectional control member 30 being arranged in the connecting bend 31. In the embodiment of the application, the connecting elbow 31 provides an accommodating space for the unidirectional control member 30, and meanwhile, the connecting elbow 31 is horizontally arranged or is arranged in a downward inclined way towards the direction of the side opening 12, so that the phenomenon that water flow is accumulated at the joint of the connecting elbow 31 and the control tube 1 and cannot be discharged in time is avoided.

As an alternative embodiment, the control member includes a control switch 71, the shower water is pressurized water, and the control switch 71 is disposed on the water inlet pipe 3 or on a water supply device of the pressurized water, so as to control the shower water cavity 60 or the bubble water cavity 61 to discharge water by controlling the on/off of the control switch 71. The control switch 71 in the embodiment of the application can be an electromagnetic switch, and the controller controls the control switch 71 to be turned on or off according to the preset time; a manual switch is also possible, and the on or off of the control switch 71 is controlled by the user.

As shown in fig. 13, the control switch in the embodiment of the present application is button-shaped, and in a single shower water outlet cycle, when the button is pressed for the first time, the shower water outlet cavity 60 is used for discharging water; when the button is pressed for the second time, the bubble water cavity 61 discharges water; pressing the button for the third time before or during the preset water cut-off interval, the bubble water cavity 61 discharges water, or pressing the button for the third time after the preset water cut-off interval, the shower water cavity 60 discharges water; after the button is pressed for the fourth time, the single shower water outlet period is finished, and the water supply of the shower water supply device is stopped.

The above technical schemes can be combined according to the need to achieve the best technical effect.

The foregoing is only illustrative of the principles and preferred embodiments of the present utility model.
