Description

Technical Field

[0001] This utility model relates to water outlet devices, and more particularly to combination shower heads. Background Technology

[0002] Existing combination shower heads, such as CN201776206U (previously authorized in the Chinese Patent Database), include a shower head body with a water inlet path, a first water path connected to the water inlet path, and a second water path. The first water path connects to the shower head's outlet panel, and the second water path connects to the shower head body via a water pipe. A valve core assembly is located at the connection between the water inlet path and the first and second water paths. The floating valve core of this valve core assembly can move left and right within a valve seat. The water inlet path of the shower head body connects to the second water path of the shower head body. The shower head body also has two outlet paths connected to the water inlet path. In particular, a normally closed switch and a switching switch are sequentially arranged between the water inlet path and the two outlet paths. The normally closed switch and the switching switch are linked by a rocker arm to achieve the switching between the shower head and the shower head water output. This valve core assembly is directly located within the shower head body, making it inconvenient for users to operate and limiting it to only two water output states. Utility Model Content

[0063] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0064] Example 1

[0065] refer to Figures 1-27 This embodiment provides a remotely switchable combination shower head, including a handheld shower head 1, a water pipe 2, a head shower head 3, a pilot valve structure 4 for controlling the opening or closing of the head shower head 3, a switching structure 5 for controlling the opening or closing of the handheld shower head 1, and a first pressure relief channel 21 and a second pressure relief channel 22 disposed within the water pipe 2; a first flow channel 23 is defined between the inner wall of the water pipe 2 and the outer walls of the first pressure relief channel 21 and the second pressure relief channel 22; in this embodiment, the pilot valve structure 4 and the switching structure 5 are respectively disposed outside the head shower head 3 and the handheld shower head 1, and the specific arrangement order is head shower head 3, pilot valve structure 4, water pipe 2, switching structure 5, and handheld shower head 1. The water pipe 2 can be a flexible hose or a rigid pipe.

[0066] The aforementioned switching structure 5, in addition to controlling the opening and closing of the handheld shower head 1, can also control the opening and closing of the pilot valve structure 4, thereby enabling remote control of the opening and closing of the head shower head 3. Since the switching structure 5 is located on the side of the handheld shower head 1, it is more convenient for consumers to operate compared to traditional shower heads where the switching structure 5 is located on the side of the head shower head 3.

[0067] To achieve the above functions, the pilot valve structure 4 has a water inlet 41 for connecting to the head shower inlet 42 of the head shower 3, a first outlet 43 for connecting to the water pipe 2 and the first flow channel 23, a second outlet 44 for connecting to the water inlet of the first pressure relief channel 21, and a third outlet 45 for connecting to the water outlet of the second pressure relief channel 22; the third outlet 45 is connected to the head shower inlet 42; thus, the water pipe 2 is always connected to the water inlet 41, regardless of whether the pilot valve structure 4 is open or closed. Therefore, the state of the pilot valve structure 4 does not affect the water inlet of the water pipe 2, and thus does not affect the water inlet of the handheld shower 1. This ensures that the water output or shut-off of the handheld shower 1 is only related to the switching structure 5, and is independent of the state of the pilot valve structure 4, making the function more stable. In this embodiment, the water inlet 42 of the head shower is connected to the second pressure relief channel 22, thereby draining the water in the second pressure relief channel 22. Alternatively, a separate drain outlet can be set to connect to the second pressure relief channel 22. As long as the water in the second pressure relief channel 22 can be drained, it is a simple replacement of this embodiment.

[0068] The switching structure 5 includes a valve body 51, which has a first inlet 52 for connecting to the first flow channel 23, a handheld shower head inlet 50 for connecting to the handheld shower head 1, a second inlet 53 for connecting to the outlet of the first pressure relief channel 21, and a third inlet 54 for connecting to the inlet of the second pressure relief channel 22. After the above settings, the water flowing into the inlet 41 can flow through the first flow channel 23 in the water pipe 2 to the first inlet 52. As long as the switching structure 5 opens the first inlet 52, the water can flow through the first inlet 52 into the handheld shower head inlet 50 to achieve water output from the handheld shower head 1. The first pressure relief channel 21 and the second pressure relief channel 22 are also connected together through the second inlet 53 and the third inlet 54. Therefore, by connecting or disconnecting the second inlet 53 or the third inlet 54 through the switching structure 5, the pressure relief channel can be opened or closed.

[0069] As described above, the switching structure 5 needs to switch the first inlet 52 on and off, as well as the second inlet 53 and the third inlet 54 on and off. There are three possible states when these are combined. Therefore, the switching structure 5 switches between the first, second, and third positions under external force. When the switching structure 5 is in the first position, the first inlet 52 is connected to the handheld shower head inlet 50, the second inlet 53 is connected to the third inlet 54, the pilot valve structure 4 is open, and the inlet 41 is connected to the head shower head inlet 42. When the switching structure 5 is in the second position, the first inlet 52 is connected to the handheld shower head inlet 50, the second inlet 53 is disconnected from the third inlet 54, the pilot valve structure 4 is disconnected, and the inlet 41 is disconnected from the head shower head inlet 42. When the switching structure 5 is in the third position, the first inlet 52 is disconnected from the handheld shower head inlet 50, the second inlet 53 is connected to the third inlet 54, the pilot valve structure 4 is open, and the inlet 41 is connected to the head shower head inlet 42. This allows for three different water output modes: handheld water output, water output from head shower 3, and water output from both handheld shower 1 and head shower 3.

[0070] The on / off state of the pilot valve structure 4 is controlled by the on / off state of the pressure relief channel. For this purpose, the pilot valve structure 4 includes a spindle 49, a cup 46, and a cup seat 47. The spindle 49 is connected to the water inlet end 42 of the head shower to form a water outlet channel. The cup 46 is provided with an overflow hole 461 that connects the water inlet end 41 and the first pressure relief channel 21.

[0071] When the switching structure 5 is in the first or third position, the pressure relief channel is open because the second inlet 53 and the third inlet 54 are connected. Water flowing into the first pressure relief channel 21 through the overflow hole 461 can enter the second pressure relief channel 22 through the second inlet 53 and the third inlet 54, and finally flow out from the head shower inlet 42. Therefore, there is no pressure buildup in the pressure relief channel. In this way, the pressure P1 on the inlet side of the rubber cup 46 is greater than the pressure P2 on the outlet side. Under the action of water pressure, the rubber cup 46 moves towards the outlet side, thereby opening the connection 48 between the spindle 49 and the inlet end 42 of the head shower. Thus, the water outlet is in a conductive state, and the head shower 3 outputs water. When the switching structure 5 is in the second position, the pressure relief channel is in a closed state, and the water flowing into the first pressure relief channel 21 cannot be discharged. Therefore, the water pressure in the first pressure relief channel 21 gradually increases, making the pressure P1 on the inlet side of the rubber cup 46 less than the pressure P2 on the outlet side. Under the action of water pressure, the rubber cup 46 moves towards the inlet side, closing the connection 48 between the spindle 49 and the inlet end 42 of the head shower.

[0072] To achieve the aforementioned switching process, the switching structure 5 includes a first part 55 for controlling the connection or disconnection between the first inlet 52 and the handheld shower head inlet 50, a second part 56 for controlling the connection or disconnection between the second inlet 53 and the third inlet 54, and an operating part 57 for controlling the switching between the first part 55 and the second part 56. Through the operating part, the user can move the first part 55 and the second part 56 to different positions to achieve different functions.

[0073] In this embodiment, the linkage between the first part 55 and the second part 56 is achieved through an operating element 571. Therefore, the operating part 57 includes the operating element 571 and a switching shaft 572 that is linked to the operating element 571. By arranging the first part 55 and the second part 56 along the length of the switching shaft 572, the operating element 571 can simultaneously drive the first part 55 and the second part 56 to rotate to achieve their respective functions without affecting each other.

[0074] To achieve the function of closing the first inlet 52, the first part 55 is a first sealing gasket 551 disposed between the outer wall of the switching shaft 572 and the valve body 51, and a first water outlet 552 is provided on the first sealing gasket 551; the switching shaft 572 has a water passage cavity 5721 communicating with the first inlet 52, and a second water outlet 5722 is provided on the side wall of the water passage cavity 5721; when the switching structure 5 is in the first position or the second position, the first water outlet 552 and the second water outlet 5722 at least partially overlap, and water in the water passage cavity 5721 can flow out through the first water outlet 552 and the second water outlet 5722; when the switching structure 5 is in the third position, the first water outlet 552 and the second water outlet 5722 are staggered, and the communication between the first inlet 52 and the water inlet end 50 of the handheld shower head is closed.

[0075] The second part 56 is a second sealing gasket 561 disposed between the outer wall of the switching shaft 572 and the valve body 51, and moving with the switching shaft 572; when the switching structure 5 is in the first position or the third position, the second sealing gasket 561 moves to the outside of the connection between the second inlet 53 and the third inlet 54; when the switching structure 5 is in the second position, the second sealing gasket 561 moves to the inside of the connection between the second inlet 53 and the third inlet 54.

[0076] In order to ensure that the second sealing gasket 561 can seal the connection between the second inlet 53 and the third inlet 54 when it moves into the connection between the second inlet 53 and the third inlet 54, the second sealing gasket 561 is connected to the switching shaft 572 by a spring 562.

[0077] Since the switching structure 5 has three positions, to ensure the user clearly knows its current position, the switching structure 5 also includes a positioning element 58, which is positioned between the valve body 51 and the operating element 571. The operating element 571 has positioning grooves corresponding to the first, second, and third positions. When the positioning element 58 is positioned between two positioning grooves, it compresses the elastic element 59 to accumulate elastic restoring force. Thus, when the switching structure 5 switches to a new position, the positioning element 58 undergoes a process of accumulating and releasing elastic restoring force, colliding with the positioning groove and emitting a sound to indicate that the switching structure 5 has completed a position switch.

[0078] In this embodiment, since the switching component drives the switching shaft 572 to rotate, the operating component 571 is a knob. Of course, a button or push button can also be used to drive the switching shaft 572 to rotate, as long as a reversing structure is added.

[0079] Example 2

[0080] refer to Figures 28-38 The difference between this embodiment and Embodiment 1 is that the pilot valve structure 4 and the switching structure 5 are respectively installed inside the head shower head 3 and the hand shower head 1. Specifically, the pilot valve structure 4 is installed inside the head shower head 3, and the switching structure 5 is installed inside the hand shower head 1. In this case, the hand shower head 1 and the head shower head 3 only need to be connected by a water pipe 2.

[0081] Since the switching structure 5 is located at the handle of the handheld shower head 1, it needs to be connected to the first pressure relief channel 21 and the second pressure relief channel 22 in the water pipe 2 to enable water output from the handheld shower head 1. Three flow channels need to be installed inside the handle of the handheld shower head 1: a shower water path 11, a pressure relief inlet water path 12 connected to the first pressure relief channel 21, and a pressure relief outlet water path 13 connected to the second pressure relief channel 22.

[0082] In this embodiment, the switching structure 5 includes a knob 501, a water divider 502, and a sealing gasket 503; the knob 501 drives the water divider 502 to rotate relative to the sealing gasket 503 to realize the opening and closing of different water channels.

[0083] First position: The water distribution body 502 and the sealing gasket 503 rotate 0° relative to each other, the shower water passage 11 is open, and the pressure relief inlet water passage 12 and the pressure relief outlet water passage 13 are connected.

[0084] Second position: The water distribution body 502 and the sealing gasket 503 rotate 45° relative to each other, the shower water passage 11 is connected, and the pressure relief inlet water passage 12 and the pressure relief outlet water passage 13 are disconnected.

[0085] Third position: the water distribution body 502 and the sealing gasket 503 rotate relative to each other by -45°, the shower water passage 11 is disconnected, and the pressure relief inlet water passage 12 and the pressure relief outlet water passage 13 are connected.

[0086] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
