In this embodiment, the first tooth member 11 is a tooth ring, which is sleeved on the end of the second valve rod 8 extending out of the second valve cavity 19 and is located between the propping portion 9 and the second valve cavity 19.

The working principle of the water outlet device in this embodiment is as follows:

as shown in fig. 2, the water outlet device is in a first water outlet state, and the water outlet state is also a default water outlet state of the water outlet device. At this time, the first valve rod 6 is in the first position under the action of the first elastic member 26, the second valve rod 8 is in the second state under the action of the second elastic member 30, and water flows in from the water inlet channel 1, flows through the first valve cavity 15, the water flow channel 2 and the second valve cavity 19, and then flows out from the second water outlet channel 4. In this state the abutment surface 12 of the first tooth 11 is close to the abutment 9 of the second valve stem 8.

When the first operating portion 28 of the first operating element 27 is pressed, as shown in fig. 3, the water outlet device is in the second water outlet state, the second elastic element 30 is compressed, the first valve rod 6 is also in the first position by the first elastic element 26, the second valve rod 8 is lifted to the first state, and water flows in from the water inlet channel 1, flows through the first valve cavity 15, the water outlet channel 2 and the second valve cavity 19, and then flows out from the third water outlet channel 5. Since the water pressure is greater than the elastic force of the second elastic member 30, the water outlet device is not automatically restored to the default state by the elastic force of the second elastic member 30 but can be maintained in the current state. In this state, the abutment 9 of the second valve stem 8 is away from the abutment face 12 of the first tooth member 11. Thus, when the first valve stem 6 is in the first position, the abutment 9 of the second valve stem 8 can be switched between being close to and far from the abutment surface 12, i.e. the second valve stem 8 can slide with respect to the first toothing 11 without interfering with the first toothing 11.

When the second operating member 31 is pressed, as shown in fig. 4, the water outlet device is in the third water outlet state, the first valve rod 6 moves from the first position to the second position along the first direction 39 to drive the gear 10 to rotate, and the gear 10 drives the first tooth member 11 to move away from the first direction 39 because the first tooth member 11 is meshed with the gear 10. Since the first tooth member 11 changes its position and thus the abutment surface 12 also changes its position, if the second operating member 31 is pressed down while the second valve stem 8 is in the first state, the abutment surface 12 and the abutment 9 will be changed from the original distance to the approach, and the first tooth member 11 and the second valve stem 8 will not interfere in this process as well. If the second operating member 31 is pressed while the second valve stem 8 is in the second state, the abutment surface 12 abuts against the abutment 9 in this process, since the abutment surface 12 is close to the abutment 9 when the second valve stem 8 is in the second state, the abutment surface 12 abuts against the abutment 9 to move the second valve stem 8 from the second state to the first state away from the first direction 39. Thus, whenever the second operating member 31 is depressed, the second valve stem 8 becomes in the first state, and its abutment 9 is close to the abutment face 12 of the first tooth 11, regardless of the state in which it is originally. After the second operating member 31 is pressed down, the water inlet passage 1 communicates with the first valve chamber 15 and thus with the first water outlet passage 3, and the state of the second valve stem 8 does not affect the water passage, and the water outlet device can be maintained in such a water outlet state because the sum of the elastic forces of the first elastic member 26 and the second elastic member 30 is smaller than the water pressure. Since the second valve rod 8 is in the first state no matter what state it is in, and the abutting portion 9 thereof is close to the abutting surface 12 of the first tooth member 11, the second valve rod 8 can be moved along the first direction 39 by pressing the second operating portion 29 of the first operating member 27, and the gear 10 is driven to rotate by the abutting portion 9 abutting the abutting surface 12, so that the first valve rod 6 is driven to move from the second position to the first position away from the first direction 39, and the water outlet device returns to the default water outlet state. Of course, the water outlet device in this embodiment can be restored to the default water outlet state by turning off water, that is, after turning off water, the first elastic member 26 and the second elastic member 30 are reset, so that the water outlet device is restored to the default water outlet state.

In this embodiment, by providing the gear 10 between the two valve rods, the first tooth portion 7 and the first tooth member 11 of the first valve rod 6 are always engaged with the gear 10, and the second valve rod 8 can freely slide relative to the first tooth member 11 when the first valve rod 6 is located at the first position, and can abut against the abutting surface 12 through the abutting portion 9 when the first valve rod 6 is not located at the first position, so as to drive the gear 10 to rotate and further control the movement of the first valve rod 6. In the practical application scenario, the first valve rod 6 is connected to the small key, the second valve rod 8 is connected to one end of the long key, and when the small key is pressed, that is, the first valve rod 6 moves to the second position, the long key can be pressed to be connected to one end of the second valve rod 8, so that the first valve rod 6 returns to the first position through the transmission of the gear 10, and then the small key is reset. Therefore, the technical scheme is equivalent to providing an operation mode for the first valve rod 6, the first valve rod 6 can be reset without a spring, and the second valve rod 8 can freely move when the first valve rod 6 is at the first position, so that the original three-function water outlet of the water outlet device is not influenced.

In this embodiment, the base is split into the base body, the first valve core base 14 and the second valve core base 18, so that the processing, the manufacturing and the assembling are facilitated.

In this embodiment, by providing the first plug portion 22 and the first groove 23 and the second plug portion 24 and the second groove 25, it is ensured that both the first valve stem 6 and the second valve stem 8 can be moved stably in the first direction 39 or away from the first direction 39.

In this embodiment, by arranging the first elastic member 26, one end of the first elastic member abuts against one end of the first valve rod 6, and the other end abuts against the seat, so that the first valve rod 6 can be stably located at the first position under the condition of low water pressure, thereby avoiding water leakage caused by that the water inlet channel 1 is simultaneously communicated with the first water outlet channel 3 and the water outlet channel 2.

In the present embodiment, by rotating the first operating element 27 having the first operating portion 28 and the second operating portion 29 to be connected to the base with the rotation shaft being located between the first operating portion 28 and the second operating portion 29 and with the second operating portion 29 being connected to the second valve stem 8, it is possible to control the movement of the second valve stem 8 between the first state and the second state by providing only one operating element.

In this embodiment, since one end of the second elastic member 30 abuts against the base and the other end abuts against the first operating portion 28, the second valve rod 8 can be stably in the second state even when the water pressure is low, so that water leakage caused by the fact that the water passing channel 2 communicates with the second water outlet channel 4 and the third water outlet channel 5 at the same time is avoided.

In this embodiment, the movement of the first valve stem 6 from the first position to the second position is facilitated by providing the second operating member 31 and connecting it to the first valve stem 6.
