The press-to-switch structure is basically the same as the press structure of an existing ballpoint pen and will not be elaborated on in detail here.

[0030] During use, the main body of the utility model includes an upper shell 41, a water inlet 50 and a lower shell 42 arranged in sequence. The outer periphery of the upper and lower ends of the water inlet are annularly provided with connecting pieces 51, and a snap-in block 52 is provided on the connecting piece. The peripheral side walls of the upper and lower shells are provided with bayonet holes 40. The connecting piece can be extended into the inner periphery of the upper and lower shells and then snap-fitted with the bayonet holes, so that the three are connected and fixed together.

[0031] Furthermore, a first water passage 60 is provided on the inner circumference between the water inlet and the upper shell. A first water outlet 61 is provided around the first water passage, which is communicable with the first water outlet. The first water passage is located on the inner circumference of the connecting piece, and sealing rings 24 are provided at both the upper and lower ends of the first water passage. An upwardly concave first groove 43 is provided within the upper shell, into which the upper end of the first water passage abuts. A downwardly concave first recess 53 is provided at the upper end of the water inlet, into which the lower end of the first water passage abuts. A first locking groove 54 is also provided around the first recess. A first protrusion 62 is provided on the outer circumference of the lower end of the first water passage, which engages with the retaining groove. This ensures that the first water passage is fixed within the body and prevents rotation, while also being held down by the upper shell and the water inlet.

[0032] Furthermore, a second water passage 70 is provided on the inner circumference between the water inlet and the lower housing. A second water outlet 71 is provided around the second water passage, which is connected to the second water outlet.

A downwardly concave second groove 45 is provided within the lower housing, into which the lower end of the second water passage abuts. An upwardly concave second recess 55 is provided at the upper end of the water inlet, into which the upper end of the second water passage abuts. A second retaining groove 56 is also provided around the second recess. A second protrusion 72 is provided on the outer circumference of the upper end of the second water passage, which engages with the retaining groove. This ensures that the second water passage is fixed within the housing and prevents rotation, while also being held in place by the lower housing and the water inlet.

[0033] In one embodiment, the first water-spreading member and the second water-spreading member are an annular body, and please refer to the drawings in the specification for details.

[0034] Preferably, a water inlet is annularly arranged on the peripheral side wall of the water inlet body, a first water outlet is formed between two connecting pieces between the water inlet body and the upper shell, and a second water outlet is formed between two connecting pieces between the water inlet body and the lower shell.

[0035] Preferably, the body further comprises a fixed shell 16, which is screwed to the upper shell, and the stator and rotor can be arranged in the fixed shell, wherein the stator can extend out of the fixed shell for user operation, and the guide groove is arranged on the inner peripheral wall of the fixed shell.

[0036] More specifically, the present invention realizes the repeated switching of the water channel's functions (water out of the first water outlet → water out of the second water outlet) when the switching movable shaft moves up and down. When the movable shaft moves up and down, the upper and lower areas of the movable shaft (the two first cylinders at the upper and lower ends) are consistent, and the water pressure areas they bear offset each other, so the movable shaft is never affected by the water pressure.

[0037] The foregoing description shows and describes preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge of the relevant art.
