In one embodiment of the present application, a plurality of teeth are provided on the convex teeth 134 on the gear member 131 and the teeth on the side rack 121 so that the push rod 120 stays within the range of movement stroke and the side rack 121 engages with the convex teeth 134 to improve the stability of the push rod 120 when driving the gear member 131, so that the movement of the push button 110 can be reliably transmitted and converted into the rotation of the gear member 131. In some preferred embodiments, as in Fig. 3, the side rack 121 and the gear member 131 are provided with an alignment mark to indicate the initial installation position so that the side rack 121 and the gear member 131 can quickly and accurately engage in the appropriate position during manufacture or maintenance.

[0021] As in Fig. 1, the rotary assembly 130 further includes a retaining member 133, wherein the retaining member 133 is adapted to direct the ratchet member 132 toward the sealing disc 140. The retaining member 133 may be a compression spring, an elastic rubber block, a tension spring, or a magnetic element, etc., as long as the ratchet member 132 can be moved away from the gear member 131. In one embodiment of the present application, the retaining member 133 is a compression spring, and the axial positions of the gear member 131 and the ratchet member 132 are provided with a cavity to accommodate the retaining member 133, which makes the structure of the rotary assembly 130 more compact and smaller by placing the retaining member 133 between the gear member 131 and the ratchet member 132.In some preferred embodiments, the cavity on the gear member 131 for receiving the retaining member 133 is a through-hole through the gear member 131, with one end of the retaining member 133 abutting the ratchet member 132 and the other end abutting other structural members, such as the mounting bracket 170 or the main body of the shower head, through the gear member 131, in order to be able to install the retaining member 133 after assembly of the gear member 131 and the ratchet member 132, or to facilitate manufacture and maintenance.

[0022] As in Fig. 3, the water line switching mechanism further comprises a mounting bracket 170, wherein the water separating disc 150 is fixedly connected to the mounting bracket 170, a water inlet cavity is formed between the water separating disc 150 and the mounting bracket 170, the sealing disc 140 is located in the water inlet cavity, and the water inlet hole 142 communicates with the water inlet cavity; a mounting cavity 171 is provided on the mounting bracket 170, the rotary assembly 130 is rotatably mounted in the mounting cavity 171, and the convex teeth 134 of the gear member 131 are located outside the mounting cavity 171.

At least one water outlet hole 151 is provided on the water separator disc 150, with at least one water outlet hole 151 being arranged in the projection area of ​​the rotational return path of the water inlet hole 142, so that the at least one water outlet hole 151 on the water separator disc 150 communicates with the water inlet hole 142 on the water separator disc 140 when the sealing disc 140 is rotated to a specific position relative to the water separator disc 150. The water separating disc 150 is provided with at least one water outlet cavity 152 on the side facing away from the sealing disc 140, wherein each water outlet cavity 152 communicates with at least one water outlet hole 151.In the embodiment of this application, there are four water inlet holes 142 on the sealing disc 140, the water inlet holes 142 being evenly arranged around the second ratchet 141. By arranging a plurality of water inlet holes 142, the water inlet holes 142 will communicate with the water outlet holes 151 when the sealing disc 140 is rotated at a small angle; there are six water outlet holes 151 on the water separator disc 150, the water inlet holes being circularly distributed, the water outlet holes 151 being opposite each other, and three water outlet cavities 152 being provided, each of the water outlet cavities 152 communicating with two of the opposite water outlet holes 151 on the water separator disc 150.By arranging the water outlet holes 151 in pairs, at least two water outlet holes 151 communicate with the water inlet holes 142 each time the water outlet holes 151 communicate with the water inlet holes 142, thereby increasing the water passage area to improve the water passage capacity.

The ratchet member 132 also rotates in the opposite direction. Since the ratchet member 132 is ratchetingly engaged with the sealing disc 140, the sealing disc 140 subsequently rotates in the opposite direction with the ratchet member 132.
