The second outlet holes of each group are communicated with the outlet cavity one by one. As a preference, a rotor 104 is also arranged in a water outlet cavity between the face cover 102 and the water outlet body 103. Under the hydraulic drive, the rotor 104 rotates to make the outlet water form massage water.
[0043] In the shower switching water outlet mechanism of the present invention, the initial state of the switching unit 200 is as Figure 5 As shown, at this time, the push rod 205 is in a state to be slid under the action of the return spring 214, and one end of the second rack 203 (that is, the rear end of the second rack 203) is close to the ratchet teeth of the ratchet 202, and the elastic arm 209 is free The end abuts against the slope top of the slope surface 2171 of the blocking arm 217; the through hole 2011 of the water diversion plate 201 coaxially linked with the ratchet 202 communicates with the water diversion hole of the water diversion body 105, so that the shower body 100 can realize a Seed water function; non-return pawl 210 meshes with ratchet 202; gear 204 meshes with first rack 215 and second rack 203 at the same time.
[0044] When it is necessary to switch to the next water outlet function, the human hand presses the button 301, and the button 301 drives the rotating rod 302 to rotate, thereby pushing the push rod 205 to slide linearly. During the sliding process of the push rod 205, the gear 204 is under the action of the push rod 205 While moving in a straight line, it rotates at the same time, thereby driving the second rack 203 to make a linear movement with enlarged stroke. With the linear movement of the second rack 203, one end of it is in contact with the non-return pawl 210 of the ratchet 202, and as the linear movement continues, the ratchet 202 is pushed to rotate a ratchet in a clockwise direction. At the same time, the second tooth The strip 203 also undergoes angular deflection. During this process, the free end of the elastic arm 209 connected to the second rack 203 moves from the top of the slope surface 2171 of the blocking arm 217 to the slope bottom of the slope surface 2171, so that the elastic arm 209 and the second The gap between the racks 203 can remain unchanged. When the ratchet wheel 202 rotates by a preset angle, the water diversion plate 201 coaxially linked with it on the one hand also rotates by a preset angle, so that the water passage hole 2011 is connected to the next set of water passage holes of the water diversion body 105, and the water outlet is switched. Function, on the other hand, push the non-return pawl 210 to swing, and when the ratchet wheel 202 rotates in place, the non-return pawl 210 meshes with the ratchet teeth of the ratchet wheel 202 again to limit the reverse rotation of the ratchet wheel 202, such as Figure 7 Shown.
[0045] When the button 301 is released by the human hand, the push rod 205 drives the gear 204 to reset under the action of the return spring 214, thereby driving the second rack 203 to axially reset. With the axial reset of the second rack 203, it is connected to the second rack. The free end of the elastic arm 209 of the rack 203 moves from the slope bottom of the slope surface 2171 of the blocking arm 217 to the slope top of the slope surface 2171. At the same time, one end of the second rack 203 located inside the elastic arm 209 remains unchanged. Sticking to the contact surface of the ratchet 202 causes the elastic arm 209 to produce a certain elastic deformation, and the elastic force received by the second rack 203 becomes larger. When one end of the second rack 203 is disengaged from the contact surface of the ratchet wheel 202, under the action of the elastic force of the elastic arm 209, the angle of the second rack 203 is reset. Finally, the gap between the second rack 203 and the elastic arm 209 It returns to the initial state. As the push rod 205 is reset, the push rod 205 pushes the rotating rod 302 to move, so that the rotating rod 302 drives the button 301 to reset.
