DETAILED DESCRIPTION OF THE INVENTION

(14) The embodiments of this invention will be described below and the technical solutions of the invention will be further illustrated in connection with the accompanying figures. However, the present invention shall not be limited to these embodiments.

First Embodiment

(15) As shown in FIG. 1, FIG. 2 and FIG. 3, the present combined shower comprises a top shower head (1), a handheld shower head (2) and an assembly hub (3) which has a water inlet (3a). The top shower head (1) has the First Outlet Chamber (1c). The handheld shower head (2) has the Second Outlet Chamber (2c). The assembly hub (3) has a water inlet cavity (3b) inside that connects to the water inlet (3a). The Second Outlet Chamber (2c) of the handheld shower head (2) always connects to the water inlet cavity (3b) through the water hose (4).

(16) Here, inside the assembly hub (3), there is also the first magnetic piece (5), an elastic piece (6) and a sealing structure which can connect or block the First Outlet Chamber (1c) of the top shower head (1) and the water inlet cavity (3b). Without any effects of external forces, under the action of the elastic force from the elastic piece (6), the first magnetic piece (5) moves and makes the sealing structure block the First Outlet Chamber (1c) of the top shower head (1) from the water inlet cavity (3b). A holder cavity (8) to hold the handheld shower head (2) is designed in front of the assembly hub (3) as well. The second magnetic piece (9) of a bulk shape is fixed on the area near the rear end of the handheld shower head (2) and the second magnetic piece (9) is arranged magnetically opposite and facing the first magnetic piece (5). Under the action of the attraction force from the second magnetic piece (9), the first magnetic piece (5) can overcome the elastic force from the elastic piece (6), moves in the opposite direction, and connects the First Outlet Chamber (1c) of the top shower head (1) to the water inlet cavity (3b).

(17) In this embodiment, the handheld shower head (2) comprises a roughly round head part (2a) and a handle part (2b). The water hose (4) is a soft hose. The elastic piece (6) is a spring and the two ends of the spring press against the inner wall of the assembly hub (3) and the first magnetic piece (5) respectively. Both of the first magnetic piece (5) and the second magnetic piece (9) are strong magnets. As shown in FIG. 5, the top shower head (1) is of an arc shape and the gap (1a) is located in the lower part. The assembly hub (3) is arranged at the rear side of the top shower head (1) and in line with the center of the top shower head (1). The assembly hub (3) connects to the top shower head (1) by the support bracket (10). The middle part of the top shower head (1) forms a holder cavity (8) for the placement of the head part (2a) of the handheld shower head (2), and the gap (1a) allows the handle part (2b) of the handheld shower head (2) to pass through it. The projecting limit blocks (1b) are fixed on both sides of the top shower head (1), which are adjacent to the gap (1a). The rear ends of the limit blocks (1b) can press against the front end of the handheld shower head (2) inside the holder cavity (8), so as to limit the position of the handheld shower head (2).

(18) As shown in FIG. 4, FIG. 5, and FIG. 6, the assembly hub (3) also has a water outlet cavity (3c) inside. The water outlet cavity (3c) connects to the First Outlet Chamber (1c) of the top shower head (1) through the Water Outlet (10a). The Water Outlet (10a) is designed inside the support bracket (10). The water outlet cavity (3c) also connects to the water inlet cavity (3b) through a water passage port (3d), and the water passage port (3d) faces forward. The sealing structure is arranged in front of the water passage port (3d), the first magnetic piece (5) is arranged in front of the sealing structure, and the elastic piece (6) is arranged in front of the first magnetic piece (5). Under the action of the elastic force from the elastic piece (6), the first magnetic piece (5) can drive the sealing structure to open or close the water passage port (3d).

(19) Specifically, the sealing structure comprises a pressure control cavity (71) located in the front area of the water passage port (3d), and a sealing washer (77) arranged between the pressure control cavity (71) and the water outlet cavity (3c). Under the action of the water pressures from the front and rear sides, the sealing washer (77) can move back and forth. When the sealing washer moves backward, it can press against the end of the water passage port (3d) and form a seal. On the sealing washer (77), there is a through hole (77a) which can connect the water inlet cavity (3b) to the pressure control cavity (71), and a pressure release passage which can connect the pressure control cavity (71) to the water outlet cavity (3c). The minimum cross-sectional area of the pressure release passage is greater than that of the through hole (77a).

(20) As shown in FIG. 11 and FIG. 12, in the present embodiment, the Assembly Hub (3) includes a cylindrical shell (11) formed integrally with the Support Bracket (10), and a Cavity (11a) is provided in the shell (11). Inside the Cavity (11a), coaxially with the Shell (11) and from the front to the back, is provided with the Mounting Seat (11b), the disc-shaped Magnet Seat (12) and Spool Seat (13), the annular Valve Seat (14), and the cylindrical Pressure Cap Connector (15). At the rear of the Pressure Cap Connector (15) is provided with a Connection Fitting (16) for water inflow and a Back Cap (17) for joining the Connection Fitting (16) to the Pressure Cap Connector (15).

(21) Here, the front end of the Mounting Seat (11b) is integrally connected to the Shell (11) and the rear end of the Mounting Seat (11b) is provided with an annular Plug (11b1). The Spool Seat (13) has an annular concave Slot (13a) at the front end thereof. The Plug (11b1) is inserted into the Slot (13a) and sealed to form the Flow Passage Cavity (72). The Magnet Seat (12) and the Elastic Piece (6) are provided within the Flow Passage Cavity (72) in the Mounting Seat (11b). The rear end of the Spool Seat (13) has several protruding cylindrical Pins (13b). The several Pins (13b) are distributed evenly around the axis of the Spool Seat (13). The Valve Seat (14) is provided with several Holes (14c) at the front end thereof. These matching Pins (13b) are inserted into these Holes (14c). The edge of the Sealing Washer (77) is pressed in between the Spool Seat (13) and the Valve Seat (14). The rear end of the Valve Seat (14) also has protruding columnar Connection Studs (14d). The front end of the Pressure Cap Connector (15) has concave Connection Holes (15a). The Connection Studs (14d) correspondingly insert into Connection Holes (15). A Limiting Slot (14e) for circumferentially limiting the Valve Seat (14) is also provided in the axial direction on the side of the Valve Seat (14). Specifically, the First Magnetic Piece (5) is fixed inside the Magnet Seat (12). The center rear side of the First Magnetic Piece (5) is connected with the two block-shaped Sealing Parts made of a rubber material. The two the Sealing Parts (5a), with the larger one in the front and the smaller one in the rear, are superposed into a step shape. The Magnet Seat (12) can move towards the Spool Seat (13) at the same time with the First Magnetic Piece (5) and the Sealing Parts (5a), under the elastic force of the Elastic Piece (6) provided on the front side of the Magnet Seat (12). The Magnet Seat (12), the First Magnetic Piece (5), the Sealing Parts (5a) and the Elastic Piece (6) are placed inside the Flow Passage Cavity (72).

(22) The rear side of the Spool Seat (13) is recessed forward to form the above-mentioned Pressure Control Cavity (71). The Pressure Control Cavity (71) opens to the rear and is opposite to the Water Passage Port (3d) located on the rear side of the Pressure Control Cavity (71) and the opening is larger in size than the Water Passage Port (3d). The Sealing Washer (77) is provided at the opening of the Pressure Control Cavity (71). The Sealing Washer (77) is made of a rubber material and whose peripheral edge is compressed and sealed by the rear side of the Spool Seat (13) and the front side of the Valve Seat (14). The Seal Washer (77) can deform to the front or to the rear, under water pressurization. When the Sealing Washer (77) is seated against the end opening of the Water Passage Port (3d) forming a seal, the unrestricted outer edge of the Sealing Washer (77) extends out of the Water Passage Port (3d) and contacts the water inside the Water Inlet Cavity (3b). The Hole (77a) is opened on the outer edge of the Sealing Washer (77).

(23) The rear side of the Spool Seat (13) also has a protruding cylindrical Pressure Release Cylinder (73). The Pressure Release Cylinder (73) is provided in the forward and backward direction. The rear end of the Pressure Release Cylinder (73) passes through the Sealing Washer (77) and the Water Passage Port (3d) and extends into the Water Outlet Cavity (3c). The front end of the Pressure Release Cylinder (73) passes through the Pressure Control Cavity (71) and is connected to the Flow Passage Cavity (72). The Sealing Washer (77) is sleeved over the Pressure Release Cylinder (73) and moves back and forth along the Pressure Release Cylinder (73). The Sealing Washer (77) is tightly abutted against the Pressure Release Cylinder (73) and is always sealed. The above mentioned pressure relief passage includes a Flow Passage Hole (74) punctured on the Spool Seat (13) and which connects the Pressure Control Cavity (71) with the Flow Passage Cavity (72) and the Pressure Release Hole (73a) in the Pressure Release Cylinder (73) and which connects the Flow Passage Cavity (72) with the Water Outlet Cavity (3c). The Flow Passage Hole (74) and the Pressure Release Hole (73a) all have larger diameter than that of the Through Hole (77a). Under the elastic force of the Elastic Piece (6), The First Magnetic Piece (5) and the Magnet Seat (12) are able to drive the Sealing Parts (5a) to press against the front end of the Pressure Release Cylinder (73) on the Spool Seat (13) and to form a seal.

(24) The Valve Seat (14) has a flat Outflow Port (14a). The Outflow Port (14a) has the above described Water Outlet Cavity (3c). The Water Passage Port (3d) is designed on the front side of the Outflow Port (14a) and is opposite to the Sealing Washer (77). The two sides of the Outflow Port (14a) and the inner wall of the valve Seat (14) form a part of the above Water Inlet Cavity (3b). The Outflow Port (14a) has both ends extending to the side wall of the Valve Seat (14) and communicating with the Water Outlet (10a) through the Vent (14b) punctured through the side wall of the Valve Seat (14). The front end of the Pressure Cap Connector (15) is in close contact with, or integral with, the rear end of the Valve Seat (14). The rear end of the Pressure Cap Connector (15) has male threads and the front end of the Back Cap (17) has female threads and has a threaded connection with the Pressure Cap Connector (15). The front end of the Connection Fitting (16) is located within the Pressure Cap Connector (15) and the Back Cap (17) and the rear end of the Connection Fitting (16) extends rearward from the middle of the Back Cap (17) and extends out of the above described Water Inlet (3a).

(25) As shown in FIG. 10, when the present combined shower is used, the assembly hub (3) is secured to the wall by tube fittings. If the handheld shower head (2) is needed, the user may hold the handle part (2b) of the handheld shower head (2) and push the handheld shower head (2) upward to have its front side detach from the limit blocks (1b). Hence, the handheld shower head (2) can be taken down. At this point, the first magnetic piece (5) inside the assembly hub (3) is not subject to the attraction force from the second magnetic piece (9) on the handheld shower head (2). Under the action of the elastic force from the elastic piece (6), it drives the sealing part (5a) to move backward and block the pressure release hole (73a). Therefore, water in the water inlet cavity (3b) flows into the pressure control cavity (71) through the through hole (77a) on the sealing washer (77), and then flows into the flow passage cavity (72) through the flow passage hole (74) but cannot flow into the water outlet cavity (3c). With the water pressure inside the pressure control cavity (71) gradually increasing, the sealing washer (77) is subject to the water pressure in the pressure control cavity (71), deforms backward and blocks the water passage port (3d), so the water inlet cavity (3b) and the water outlet cavity (3c) are disconnected. Hence, the water can only flow into the outflow cavity of the handheld shower head (2) through the water hose (4), and sprays out from the spraying panel of the handheld shower head (2), while the top shower head (1) does not spray water.

(26) Conversely, when the top shower head (1) is needed, the user may put the head part (2a) of the handheld shower head (2) into the holder cavity (8) which is slightly bigger than the head part (2a) of the handheld shower head (2). At this point, the second magnetic piece (9) inside the handheld shower head (2) is subject to the attraction force from the first magnetic piece (5) and secures the handheld shower head (2). In coordination with the two limit blocks (1b), a three-point fixation of the handheld shower head (2) is achieved. Meanwhile, the first magnetic piece (5) is subject to the attraction force from the second magnetic piece (9) inside the handheld shower head (2), overcomes the elastic force from the elastic piece (6), and moves forward. This makes the sealing part (5a) separate from the pressure release hole (73a), and the pressure release hole (73a) is open again. Because both hole diameters of the pressure release hole (73a) and the flow passage hole (74) are greater than that of the through hole (77a), the flow rate of the water in the pressure control cavity (71) flowing into the water outlet cavity (3c) through the flow passage hole (74) and the pressure release hole (73a), is greater than the supplying rate of the water in the water inlet cavity (3b) flowing into the pressure control cavity (71) through the through hole (77a). The water pressure in the pressure control cavity (71) gradually decreases. The sealing washer (77) is subject to the higher water pressure in the water inlet cavity (3b), deforms toward the pressure control cavity (71) and detach from the water passage port (3d), so that the water outlet cavity (3c) connects to the water inlet cavity (3b) through the water passage port (3d). The water can directly flow into the outflow cavity of the top shower head (1) through the water passage port (3d) and the water outlet cavity (3c), and then spray out from the spraying panel of the top shower head (1). At the same time, the handheld shower head (2) is also spraying water, so the handheld shower head (2) and the top shower head (1) surrounding the handheld shower head (2) are both spraying water. This largely increases the water spraying area.

(27) During the usage of the present combined shower, the connection control over the water passage of top shower head (1) is achieved by the user taking down or hanging up the handheld shower head (2), without manually turning the switch knob on the top shower head (1). It does not require a tall stature of the user and is easier to use.

Second Embodiment

(28) As shown in FIG. 6, this Second Embodiment is roughly the same as the technical proposal in First Embodiment. The differences are:

(29) The sealing structure comprises a swinging plate (75) hinged on the front part of the water passage port (3d). The elastic piece (6) comprises a torsion spring connected to the hinge point. Under the action of the elastic force from the torsion spring, the swinging plate (75) can lean against the end of the water passage port (3d) and forms a seal. The first magnetic piece (5) is connected to the front side of the swinging plate (75) and can drive the swinging plate (75) to swing back and forth. Of course, the first magnetic piece (5) may also be connected to the rear side of the swinging plate (75) as needed.

(30) When the top shower head (1) is not required to spray water, the second magnetic piece (9), along with the handheld shower head (2), is taken down. Under the action of the elastic force from the torsion spring, the swinging plate (75) can lean against the end of the water passage port (3d) and disconnects the water inlet cavity (3b) from the water outlet cavity (3c). Conversely, under the action of the attraction force from the second magnetic piece (9), the first magnetic piece (5) drives the swinging plate (75) which is connected to it to swing forward, and hence the water passage port (3d) opens, so the water in the water inlet cavity (3b) flows through the water passage port (3d), enters into the water outlet cavity (3c) and flows into the outflow cavity of the top shower head (1).

Third Embodiment

(31) As shown in FIG. 7, this Third Embodiment is roughly the same as the technical proposal in First Embodiment. The differences are:

(32) The sealing structure comprises a sheet-like sealing piece (76). The sealing piece (76) is fixed on the rear side of the first magnetic piece (5), and the sealing piece (76), along with the first magnetic piece (5) can tightly press against the end of the water passage port (3d) and forms a seal, under the action of the elastic force from the elastic piece (6).

(33) The description of the preferred embodiments thereof serves only as an illustration of the spirit of the invention. It will be understood by those skilled in the art that various changes or supplements in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
