1. 1. Bei der axial angetriebene Wasserumleitungsvorrichtung treibt die Antriebseinheit axial die Stopfenstange an, um axial in der inneren Wassereinlass-Kavität zu gleiten. Die Stopfenstange gleitet in der inneren Wassereinlasskavität, um ein Umschalten einer Verbindung zwischen dem Wassereinlasskanal und den mindestens zwei Wasserauslasskanäle zu erreichen, wodurch es vermieden wird, dass eine Drehscheibenwasserkanalschaltstruktur einen relativ großen radialen Raum benötigt, sodass der Duschkopf einen guten Umschalteffekt und einen kleinen Dichtungsraum aufweist, und deshalb passender für Duschköpfe mit kleinen Durchmesser ist.
2. 2. Der Wasserauslass des Wassereinlasskanals und der Wassereinlass jedes Wasserauslasskanals sind versetzt. Die Stopfenstange ist mit einem ersten Dichtungselement versehen, das in dichtendem Kontakt mit einer inneren Wand der inneren Wassereinlass-Kavität ist. Die Stopfenstange treibt das erste Dichtungselement an, um in der inneren Wassereinlass-Kavität zu gleiten, wodurch ein Umschalten einer Verbindung zwischen dem Wasserauslass des Wassereinlasskanals und den Wassereinlässen der mindestens zwei Wasserauslasskanäle erreicht wird, und das Umschalten der Wasserauslasskanäle durch die Bewegung des ersten Dichtungselementes mit einer einfachen Struktur, einer einfachen Ausführung und einer guten Stabilität erreicht wird.
3. 3. Das zweite Dichtungselement ist ebenfalls in dichtendem Kontakt mit der inneren Wand der inneren Wassereinlass-Kavität, so dass die Wasserdurchgangsnut der Stopfenstange und die innere Oberfläche der inneren Wassereinlass-Kavität miteinander zusammenwirken, um eine Wasserdurchgangkavität zu umgrenzen. Wenn der Wassereinlass jedes Wasserauslasskanals und das Wasserauslass des Wassereinlasskanals mit der Wasserdurchgangkavität verbunden sind, ist der Wassereinlasskanal mit dem entsprechenden Wasserauslasskanal verbunden. Wegen der Gestaltung der Wasserdurchgangkavität tritt das Wasser in die Wasserauslässe der Wasserauslasskanäle durch die Wasserdurchgangkavität nachdem es die Wasserdurchgangkavität durchströmt. Ferner, da die Wasserdurchgangkavität voller Wasser ist, werden Gegendrücke am oberen Ende und am unteren Ende der Wasserdurchgangkavität in einer Aufwärtsrichtung und in einer Abwärtsrichtung aufgebaut. Wenn die Stopfenstange bewegt wird, gleichen sich die Gegendrücke in der Wasserdurchgangkavität in der Aufwärtsrichtung und in der Abwärtsrichtung gegeneinander aus, sodass di Stopfenstange nicht von den Gegendrücke beeinflusst wird. Somit wird ein arbeitssparende Effekt erreicht und es wird vermieden, dass die Stopfenstange wegen einer Erhöhung der Gegendrücke schwer zu bewegen oder gesperrt ist, wenn das Wasserdruck hoch ist.
4. 4. Das erste elastische Element ist zwischen dem Knopf und der Druckantriebsstruktur vorgesehen. Die Druckantriebsstruktur erstreckt sich in die innere Wassereinlass-Kavität und liegt an der Stopfenstange an. Das zweite elastische Element ist zwischen der Stopfenstange und der inneren Wassereinlass-Kavität vorgesehen. Das erste elastische Element und das zweite elastische Element sind axial zusammenschiebbar. Die Druckantriebsstruktur treibt die Stopfenstange an, sodass der Aufbau einfach und die Stabilität gut ist.
5. 5. Der Knopf wird zum Drücken des ersten Dorns verwendet, wodurch der erste Dorn in der Schafthülse gleitet. Der erste Dorn und der zweite Dorn werden durch den Kontaktantrieb zwischen schrägen Flächen verbunden. Der erste Dorn treibt den zweiten Dorn an, sodass sich der zweite Dorn synchron in der Schafthülse dreht und bewegt. Der zweite Dorn treibt die Stopfenstange an, sodass sich die Stopfenstange mit einer einfachen Struktur, einer einfachen Ausführung und einer guten Stabilität aufwärts und abwärts bewegt.

In comparison with the prior art, the technical solution of the present utility model has the following advantages:

1. 1. In the axially driven water diverter, the drive unit axially drives the stopper rod to slide axially in the inner water inlet cavity. The stopper rod slides in the inner water inlet cavity to achieve switching of a connection between the water inlet channel and the at least two water outlet channels, thereby avoiding that a hub water channel switching structure requires a relatively large radial space such that the shower head has a good switching effect and a small sealing space , and therefore is more suitable for small diameter showerheads.
2. 2. The water outlet of the water inlet channel and the water inlet of each water outlet channel are offset. The stopper rod is provided with a first sealing member which is in sealing contact with an inner wall of the inner water inlet cavity. The stopper rod drives the first sealing member to slide in the inner water inlet cavity, whereby switching of a connection between the water outlet of the water inlet channel and the water inlets of the at least two water outlet channels is achieved, and switching the Wasserauslasskanäle by the movement of the first sealing element with a simple structure, a simple design and a good stability is achieved.
3. 3. The second sealing member is also in sealing contact with the inner wall of the inner water inlet cavity such that the water passageway of the stopper rod and the inner surface of the inner water inlet cavity cooperate with each other to define a water passageway cavity. When the water inlet of each water outlet channel and the water outlet of the water inlet channel are connected to the water passageway, the water inlet channel is connected to the corresponding water outlet channel. Because of the design of the water passage cavity, the water enters the water outlets of the water outlet channels through the water passage cavity after passing through the water passageway cavity. Further, since the water passageway cavity is full of water, back pressures at the upper end and at the top of bottom end of the water passage cavity in an upward direction and in a downward direction. When the stopper rod is moved, the back pressures in the water passageway cavity balance each other in the upward direction and the downstream direction, so that the stopper rod is not affected by the back pressures. Thus, a labor-saving effect is achieved and it is avoided that the stopper rod is difficult to move or lock because of an increase in the back pressures when the water pressure is high.
4. 4. The first elastic element is provided between the button and the pressure drive structure. The pressure drive structure extends into the inner water inlet cavity and abuts against the stopper rod. The second elastic member is provided between the stopper rod and the inner water inlet cavity. The first elastic element and the second elastic element are axially collapsible. The pressure drive structure drives the stopper rod so that the structure is simple and the stability is good.
5. 5. The button is used to push the first mandrel, causing the first mandrel to slide in the shaft sleeve. The first mandrel and the second mandrel are connected by the contact drive between inclined surfaces. The first mandrel drives the second mandrel so that the second mandrel rotates and moves synchronously in the shaft sleeve. The second mandrel drives the stopper rod so that the stopper rod moves up and down with a simple structure, a simple design and a good stability.
