Referring to fig. 5 and fig. 6, the end wall of the end of the water outlet channel 113 away from the water inlet cavity 111 is respectively provided with a matching cavity 1135 and a plurality of matching grooves 1137, the plurality of matching grooves 1137 are symmetrically distributed along the periphery of the matching cavity 1135, and the bottom of the matching cavity 1135 is convexly provided with a plurality of second helical teeth 1139, and the plurality of second helical teeth 1139 are circumferentially distributed at intervals. In this embodiment, the number of the second helical teeth 1139 is four corresponding to the first helical teeth 1331, and the corresponding circumferential spacing distribution, and the number of the mating grooves 1137 is two corresponding symmetrical distribution.
When the switching teeth 133 are matched with the housing 110 in the water stop state as shown in fig. 2, the first inclined teeth 1331 are crossly matched with the second inclined teeth 1139, and the limiting ribs 1333 are inserted into the matching grooves 1137, and at this time, the water inlet 1131 is closed by the third annular ribs 1319 under the action of the elastic member 150.

At this time, the operator pushes the button 2111, and the button 2111 pushes the push rod 170 to move along the axial direction of the water outlet channel 113, so that the four ribs 171 respectively abut against the respective inclined surfaces of the four first inclined teeth 1331, and further push the four first inclined teeth 1331 to gradually withdraw from the gaps between the second inclined teeth 1139 along the axial direction, and the elastic member 150 is gradually compressed in the process. When the four first helical teeth 1331 just completely exit the gap between the second helical teeth 1139, the first helical teeth 1331 are no longer limited by the side walls of the second helical teeth 1139, and the inclined surfaces of the first helical teeth 1331 slide relative to the convex edges 171, i.e. the switching teeth 133 rotate until the inclined surfaces of the first helical teeth 1331 are engaged with and abutted against the inclined surfaces of the second helical teeth 1139. At this time, the external force is removed, the elastic member 150 reversely pushes the balance shaft 131, and the first helical teeth 1331 and the second helical teeth 1139 on the switching teeth 133 are respectively attached to the inclined surfaces of the corresponding sliding surfaces, so that the switching teeth 133 further rotate until the four first helical teeth 1331 respectively fall into the adjacent gaps defined by the four second helical teeth 1139. The two limit ribs 1333 are inserted into the two matching grooves 1137, the third annular rib 1319 is attached to the wall surface provided with the water inlet 1131, the water inlet 1131 is closed, and the sprinkler water stopping structure is switched to a water stopping state shown in fig. 2.
When the water stop state is switched to the water through state, the first ring wall 1315 balances the static water pressure borne by the third ring wall 1319, so that the process of pressing the button 2111 by external force only needs to overcome the elastic force of the elastic member 150. When the water-passing state is switched to the water-stopping state, the first ring wall 1315 balances the dynamic water pressure received by the second ring wall 1317, so that the external force is only required to overcome the elastic force of the elastic member 150 when the button 2111 is pressed by the external force. Therefore, in this embodiment, the sprinkler water stop structure 100 has the function of balancing water pressure, and realizes easy switching between the water stop state and the water passing state.
Therefore, the shower assembly 200 provided in this embodiment is convenient to operate, and the user experience is better.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
