9. 9. Das zweite Wasserauslassstück ist am Boden des Schaltkanals angeordnet und kann insbesondere an eine Handbrause oder andere Wasserauslassvorrichtungen angeschlossen werden. Durch die Betätigung der Hebebaugruppe bewegt sich das Stöpselteil an verschiedenen Positionen entlang der vertikalen Richtung, so dass die Wasserdurchgangsöffnung so umgeschaltet werden kann, dass sie entweder mit der ersten Wasserverteilungsöffnung oder der zweiten Wasserverteilungsöffnung in Verbindung steht, die Wasserauslassrichtung geändert wird und verschiedene Nutzungsanforderungen erfüllt werden.
10. 10. Wenn die Zugstange und der Hebegriff nicht angehoben werden und in der untersten Position stehen bleiben, steht die Zugstange unter der Wirkung des elastischen Teils und treibt das Stopfenstück an, um die zweite Wasserverteilungsöffnung zuverlässig zu verschließen. Zu diesem Zeitpunkt steht die Wasserdurchgangsöffnung mit der ersten Wasserverteilungsöffnung in Verbindung. Sobald der Wassermischventilkern den Wassermischkanal so steuert, dass er mit dem ersten Wasserkanal und/oder dem zweiten Wasserkanal in Verbindung steht, fließt Wasser in den zweiten Rohrteil, und das erste Wasserauslassstück gibt Wasser aus. Wenn die Zugstange und der Hebegriff angehoben werden und in der höchsten Position anhalten, verstopft das Stopfenstück die Stopfenfläche. Zu diesem Zeitpunkt steht die Wasserdurchgangsöffnung mit der zweiten Wasserverteilungsöffnung in Verbindung. Wenn der Wassermischventilkern den Wassermischkanal öffnet, um mit dem ersten Wasserkanal und/oder dem zweiten Wasserkanal zu kommunizieren, fließt das Wasser, das von der Wasserdurchgangsöffnung in den Schaltkanal fließt, aus der zweiten Wasserauslassloch heraus. Zu diesem Zeitpunkt hält die drucktragende Fläche der Wirkung des Wasserflusses im Schaltkanal stand und stoppt zuverlässig an der aktuellen Position, so dass das Stopfenstück die Stopfenlfläche zuverlässig verstopfen kann.

Compared to the prior art, the above solution has the following beneficial effects:

1. 1. The water channel main body includes the first mounting base, the second pipe part, the second mounting base and the second pipe part connected sequentially along the first direction, the first mounting base having the water passage surface, the first water channel, the second water channel and the water mixing channel is provided, wherein the first water channel and the second water channel are both used for access to the water source. The water outlet ends of the first water channel and the second water channel are both on the water passage surface arranged, the water inlet end of the water mixing channel is also arranged on the water passage surface, and the water passage surface is suitable to cooperate with the external water mixing valve core, and the water mixing valve core controls the first water channel and the second water channel to communicate with or be separated from the water mixing channel , to realize the functions of opening and closing water and adjusting the flow rate. The water mixing channel communicates with the water passage hole on the second mounting base through the first pipe part, and the switching channel is used for the elevating assembly to divide water in the bathtub faucet to assemble, and the elevating assembly controls the water passage hole to communicate with the first water distribution hole or to be separated from it in order to realize the water output or the water drainage of the second pipe part. In the technical solution, the water channel main body is an integrally molded component and has little difficulty in structure formation and few parts, so assembly is facilitated, assembly cost is low, and there is no water leakage.
2. 2. The first submount includes a base body, a first connection pipe, and a second connection pipe. The base body is used to be placed in the body of the bathtub faucet and form the water path and the water passage surface. The first connection pipe and the second connection pipe can be used for a water inlet pipe fitting to be reliably inserted to be connected with bent feet. The structure is simple and the connection is convenient. The extending directions of the first connecting pipe and the second connecting pipe are both perpendicular to the first direction, so that during actual assembly, the first connecting pipe and the second connecting pipe are parallel to the wall surface and face the curved feet on two sides, respectively, thereby making the outer tubular Component can be mounted easily and stably and the connection of the waterway is realized. It should be noted that the opening ends of the first connection pipe and the second connection pipe are respectively on two sides of the first mounting base, and the first connection pipe and the second connection pipe are parallel to the wall surface. The first connection pipe and the second connection pipe can be used for the tubular component to assemble in an inserted connection manner and communicate with the cold water curved foot and the hot water curved foot on the wall surface. The connection of the first mounting base and the crooked foot on the wall surface is not limited by the size of the water channel main body, and reliable abutting and joining with the crooked foot can be flexibly realized even if there are different pitches of the crooked feet due to the assembly error , so that the water channel main body has high universality.
3. 3. The lower end of the base body is flush with a lower end of the second mounting base. When assembling, the lower end of the base body and the lower end of the second mounting base are jointly supported on the bottom wall of the bathtub faucet, so that the water channel main body has high stability in the bathtub faucet.
4. 4. An end surface of the second pipe part is inclined downwards. During actual use, the end face of the second pipe part may face toward an inner cavity of a bathtub, so that the flow of water discharged from the second pipe part can flow into the inner cavity of the bathtub more easily and not splash out of the bathtub.
5. 5. A stopper flange is formed on a peripheral wall of an end portion of the second pipe portion remote from the second mounting base. Due to the arrangement of the stop flange, the end face of the second pipe part has a larger contact area for hermetic contact with a water outlet part, as a result of which the sealing properties between the water channel body and the water outlet part are improved.
6. 6. The bathtub faucet provided by the technical solution adopts the water channel main body, so the bathtub faucet has the same advantages as the water channel main body.
7. 7. The faucet body includes a housing and a back cover. The mounting hole is formed in the rear of the case, which allows the water channel main body to be conveniently mounted from the mounting hole into the inner cavity of the case, and then shielded by the rear cover. During actual use, the back cover faces towards the cavity wall so that the A construction trace of the water channel main body is not visually visible, and good shielding effect and excellent aesthetic properties are achieved.
8. 8. By arranging the first water outlet piece, the flow of water discharged from the second pipe part can be diverted in a desired shape.
9. 9. The second water outlet piece is arranged at the bottom of the switching channel and can be connected in particular to a hand shower or other water outlet devices. By operating the lifting assembly, the plug part moves to different positions along the vertical direction, so that the water passage hole can be switched to communicate with either the first water distribution hole or the second water distribution hole, the water outlet direction is changed, and various use requirements are met .
10. 10. When the pull rod and the lifting handle are not lifted and remain in the lowest position, the pull rod is under the action of the elastic part and drives the plug piece to reliably close the second water distribution hole. At this time, the water passage hole communicates with the first water distribution hole. Once the water mixing valve core controls the water mixing channel to communicate with the first water channel and/or the second water channel, water flows into the second pipe part and the first water outlet piece discharges water. When the drawbar and lift handle are raised and stop at the highest position, the plug piece plugs the plug face. At this time, the water passage hole communicates with the second water distribution hole. When the water mixing valve core opens the water mixing channel to communicate with the first water channel and/or the second water channel, the water flowing into the switching channel from the water passage hole flows out from the second water outlet hole. At this time, the pressure-bearing surface withstands the effect of water flow in the switching channel and reliably stops at the current position, so that the plug piece can reliably plug the plug oil surface.
