Example 4

With continued reference to fig. 1-4 based on embodiments 1-3, in the embodiment of the present invention, the implementation manner of the on-off valve 20 includes a plurality of ways, and one way that can be realized is that the on-off valve 20 includes a control assembly 21 and a sealing diaphragm 22.

Referring to fig. 4, the on-off valve 20 is in the second state, the sealing diaphragm 22 is away from the passage port 13, and a first gap is provided between the sealing diaphragm 22 and the passage port 13. At this time, the medium in the first passage 11 may enter the second passage 12 through the first gap, thereby performing the exhausting operation.

The embodiment of the utility model provides an in, control assembly 21 and sealed diaphragm 22 carry out abundant structure simplification under the prerequisite that satisfies the functional requirement, improve the compact and the use reliability of shower nozzle structure.

Example 5

With continued reference to fig. 1 to 4 based on embodiment 4, in an embodiment of the present invention, the control assembly 21 may be implemented in a manner that the control assembly 21 includes a valve seat 211 and a control rod 212. The valve seat 211 is connected to the tubular body 1021, and the valve seat 211 has a control chamber therein extending in the direction of the extension of the tubular body 1021. A control rod 212 is located within the control chamber and is movably connected to the valve seat 211. When the control rod 212 is moved in the direction of extension of the control chamber, the sealing diaphragm 22 is moved closer to or further away from the passage opening 13.

The valve seat 211 is attached to the tubular body 1021 in a manner that includes, but is not limited to, a threaded connection, a snap fit, etc. To facilitate the installation of the valve seat 211, an operating portion 2114 is provided on the outer surface of the valve seat 211. Implementations of the handling portion 2114 include, but are not limited to, handling ears at opposite ends of the outer surface of the valve seat 211 by which the valve seat 211 can be manually installed to enable quick installation of the valve seat 211 without tools.

The control rod 212 can be moved manually or electrically, and in case of electrical movement, the control assembly 21 further includes a driving motor, and a driving force is applied to the control rod 212 through a driving shaft of the driving motor to complete the movement of the control rod 212.

In this embodiment, a manual moving manner is taken as an example for description.

The connection between the control rod 212 and the valve seat 211 can be achieved in various ways, for example, referring to fig. 1 to 4, an operation handle is further disposed on the control rod 212, and a user can operate the control rod 212 through the operation handle, for example, the operation handle drives the control rod 212 to move along the extending direction of the control cavity. Of course, it is understood that the handle is only one implementation of the control rod 212, and in some 2 embodiments of the present invention, the control rod 212 can also implement its function without the handle. In the above or following embodiments, the control rod 212 may be provided with an operating handle, or not. The arrangement mode of the operation handle includes other modes besides the modes shown in fig. 1 to 4, and the description is omitted here.

In the embodiment of the present invention, the setting mode of the sealing diaphragm 22 includes the following several types, and one realizable mode is that the sealing diaphragm 22 is located between the control rod 212 and the channel port 13, and when the valve seat 211 is connected to the tubular main body 1021, the edge of the sealing diaphragm 22 is extruded on the end surface. In this way, when the control rod 212 moves toward the passage opening 13 along the extending direction of the control chamber, the portion at the middle position of the sealing diaphragm 22 is moved, and the passage opening 13 is sealed by the portion at the middle position of the sealing diaphragm 22. When the control rod 212 moves along the extension direction of the control chamber and moves away from the passage opening 13, the sealing diaphragm 22 rebounds under the action of its elastic restoring force, so that a first gap is formed between the sealing diaphragm 22 and the passage opening 13.

Alternatively, the sealing diaphragm 22 is arranged at the end of the control rod 212 facing the passage opening 13. In this way, when the control rod 212 moves toward the passage opening 13 along the extending direction of the control chamber, the portion at the middle position of the sealing diaphragm 22 is moved, and the passage opening 13 is sealed by the portion at the middle position of the sealing diaphragm 22. When the control rod 212 moves along the extension direction of the control chamber away from the passage opening 13, the sealing diaphragm 22 is moved away from the passage opening 13, so that a first gap is formed between the sealing diaphragm 22 and the passage opening 13. To further ensure the tightness of the passage opening 13, a sealing ring may be provided between the control rod 212 and the inner wall of the control chamber.

Example 6

With continued reference to fig. 1 to 4 on the basis of example 5, in an embodiment of the invention, in a realisable manner, at least two mounting slides 2111 are provided on the side wall of the control chamber, in the direction of extension of the control chamber. At least two control slideways 2112 are arranged on the side wall of the control cavity along the radial direction of the control cavity, and each control slideway 2112 is communicated with one installation slideway 2111. Along the extension direction of the control chamber, there is a height difference between the end of the control runner 2112 connected to the mounting runner 2111 and the end of the control runner 2112 remote from the mounting runner 2111.

The control rod 212 includes a rod body 2121 and at least two protrusions 2122 disposed on the rod body 2121, the protrusions 2122 can enter the control cavity along the installation slideway 2111 and enter the control slideway 2112 at a position where the installation slideway 2111 communicates with the control slideway 2112, and the protrusions 2122 drive the rod body 2121 to move along the extending direction of the control cavity when moving along the control slideway 2112.

Control rod 212 may be advanced into the control cavity through mounting runner 2111, and tab 2122 may be advanced along mounting runner 2111 into control runner 2112. Also, removal of the control rod 212 from the valve seat 211 may be accomplished by installing the slide 2111.

When the bump 2122 moves along the control slideway 2112, the rod body 2121 rotates correspondingly, and because there is a height difference between the two ends of the control slideway 2112, the bump 2122 moves a certain distance along the extending direction of the control cavity in the process that the bump 2122 moves from one end of the control slideway 2112 to the other end, that is, the rod body 2121 moves a certain distance along the extending direction of the control cavity, and the rod body 2121 can drive the sealing diaphragm 22 to move when moving towards the channel opening 13.

For example, in the initial state, the bump 2122 is located at an end of the control runner 2112 away from the passage opening 13, and at this time, there is a first gap between the sealing diaphragm 22 and the passage opening 13, and the medium in the first passage 11 can enter the second passage 12 to be discharged.

At this time, by rotating the control rod 212 in the switch valve 20, when the control rod 212 rotates, the protrusion 2122 gradually moves towards the end of the control slide 2112 close to the passage opening 13 along the end of the control slide 2112 away from the passage opening 13, during the movement, the protrusion 2122 correspondingly moves along the extending direction of the control cavity, and the protrusion 2122 drives the rod body 2121 to move when moving. When the rod 2121 moves along the extending direction of the control chamber, the sealing diaphragm 22 is driven to move towards the channel opening 13. When the projection 2122 moves to the end of the control slide 2112 near the ram, the sealing diaphragm 22 completely blocks the passage opening 13, and the first gap disappears.

Example 7

On the basis of embodiment 6, propose embodiment 7, embodiment 7 improves control slide 2112 on the basis of embodiment 6, the embodiment of the utility model provides an, the one end that control slide 2112 and installation slide 2111 are connected has first spacing groove. One end of the control slide 2112, which is far away from the installation slide 2111, is provided with a second limit groove. Along the extending direction of the control cavity, a height difference is formed between the first limiting groove and the second limiting groove. When the protrusion 2122 enters the first limiting groove or the second limiting groove along the control slideway 2112, the rod 2121 is driven to move along the axial direction of the control cavity.

When the bump 2122 moves along the control slideway 2112, the rod body 2121 rotates correspondingly, and the positions of the control slideway 2112 are all on the same rotating surface, and there is no height difference along the extending direction of the control cavity. Thus, when the block 2122 moves in the control slide 2112, the block 2122 does not move correspondingly along the extending direction of the control chamber. The height difference exists between the first and second limiting grooves, so that when the first or second limiting grooves at the two ends are moved, the bump 2122 moves a certain distance correspondingly, that is, the rod 2121 moves a certain distance along the extending direction of the control cavity, and the rod 2121 can drive the sealing diaphragm 22 to move when moving to the passage opening 13.

For example, when the control rod 212 in the switch valve 20 is rotated, the protrusion 2122 comes out of the first limit groove and enters the control slide 2112 when the control rod 212 is rotated, and when the protrusion 2122 moves along the control slide 2112, the protrusion 2122 does not move correspondingly along the extending direction of the control cavity. When the protrusion 2122 enters the second limiting groove, the protrusion 2122 moves along the extending direction of the control cavity, and the protrusion 2122 moves to drive the rod 2121 to move. When the rod 2121 moves along the extending direction of the control chamber, the sealing diaphragm 22 is driven to move.
