[0035] One end of the pressing member 6 presses against the switch member 5, and the other end extends outside the mounting cavity 2 to form a pressing end. One end of the switch member 5 is provided with a first sealing part 52. The switch member 5 is maintained in its initial position by the support of the elastic member 4. The first sealing part 52 isolates the inlet 21 and the outlet 22, forming a water-stopping state.

Figure 7 and Figure 8As shown. The other end of the switch element 5 is provided with a second sealing part 53. When the switch element 5 is in the water-stopped state, the second sealing part 53 isolates the switching space 24, which houses the pressing element 6 in the mounting cavity 2, from the water outlet 22. Alternatively, in other embodiments, when the switch element 5 is in the water-outflow state, the switching space 24 is connected to the water outlet 22. The switch element 5 is provided with a water passage 54, which connects the switching space 24 and the water inlet channel 1, preventing the switch element 5 from being subjected to water force only on one side when the water is stopped.

[0036] In one embodiment, the mounting cavity 2 has a stepped hole 25 between the inlet 21 and the outlet 22. The stepped hole 25 forms a channel between the inlet 21 and the outlet 22, and its opening faces the inlet 21. The diameter of the first sealing part 52 is larger than that of the stepped hole 25, and the first sealing part 52 abuts against the peripheral wall of the stepped hole 25 in a water-stopped state. Preferably, the stepped hole 25 is conical or trumpet-shaped for better sealing. In another embodiment, the opening of the switching space 24 facing the inlet 21 is also conical or trumpet-shaped, and the other end, along with the portion of the pressing member 6 extending out of the mounting cavity 2, is provided with a sealing mechanism to prevent water leakage from the mounting cavity 2.

To improve the stability when the pressing member 6 and the switch 5 are connected, the end of the pressing member 6 is provided with a limiting post for inserting into the water outlet, and the end of the switch 5 is provided with a water passage notch connecting the water outlet and the switching space 24 to avoid blockage.

[0039] In one embodiment, the pressing component 6 includes a switching rod 61 and a pressing rod 62. The elastic element 4, the switch element 5, the switching rod 61, and the pressing rod 62 are sequentially installed into the mounting cavity 2, with the pressing rod 62 extending out from the opening of the mounting cavity 2. The top end of the switching rod 61 has a lower ratchet, and the bottom end of the pressing rod 62 has an upper ratchet. The inner wall of the mounting cavity 2 has a guide groove for the upper ratchet to slide. The elastic element 4, the switch element 5, the switching rod 61, the pressing rod 62, and the mounting cavity 2 constitute a ballpoint pen pressing switching mechanism. The switch element 5 switches states through the ballpoint pen pressing switching mechanism, which has the advantages of simple structure, convenient operation, and mature reliability. It should be noted that the ballpoint pen pressing switching mechanism is existing technology, and its working principle of switching step by step by pressing will not be described here.
