The lowermost end and the uppermost end are defined herein with respect to the outlet end of the outlet portion as the lower side. In the present embodiment, the positioning of the sliding member 30 is achieved by the friction force between the sealing ring sleeved on the sliding member and the wall of the sliding cavity, and whether the sliding member 30 reaches the first position, the second position and the third position is determined by whether the elastic portion abuts against the corresponding positioning groove 223. Accordingly, the positioning grooves 223 are correspondingly provided in three, and the position of each positioning groove 223 corresponds to the first position, the second position, and the third position, respectively.
When the sliding piece 30 moves to the first position as the initial position, the sliding block 34 is located at the bottom end of the inclined groove 23, and the sliding block 34 is limited by the second block 225, so that the sliding block 34 can not move any more, the sliding piece 30 can not move any more, and the bottom end of the sliding piece 30 is abutted to the water outlet piece 14, thereby limiting the limit position of the bottom end of the sliding piece 30 and the limit position of the rotating piece rotating in the direction; meanwhile, in the first position, the first water dividing portion 321 on the sliding member 30 faces the water passing opening 105, and water can enter the water passing passage 3212 through the water passing opening 105, the first water dividing portion 321 and the first opening 3211, and then enter the first water outlet 142 of the water outlet member 14 from the water passing passage 3212 to form water outlet.
The rotating member is rotated to make the sliding member 30 reach a third position, in which the second water diversion part 322 on the sliding member 30 is opposite to the water passing port 105, and the water flow passing through the water passing port 105 is blocked by the second sealing ring 42 and the third sealing ring 43, thereby cutting off the communication with the first water outlet 142 and the second water outlet 144.
Continuing to rotate the rotating member to make the sliding member 30 reach the second position, at this time, the sliding block 34 will abut against the limiting portion 217, the rotating member cannot continue to rotate, and the sliding member 30 cannot continue to move upward; the third water dividing part 323 on the sliding part 30 at the position is over against the water passing opening 105, the water passing gap 35 formed by the matching of the outer wall of the sliding part 30 at the third water dividing part 323 and the inner wall of the sliding cavity is communicated with the water passing opening 105, and water flow can enter the communicating water channel 143 through the water passing opening 105, the water passing gap 35 and the second opening 141 and then reach the second water outlet 144 to form water outlet. Then, the rotating member is rotated in the other direction, and the sliding member 30 returns to the third position and the first position in sequence.
In addition, because the rotating part is installed at the upper end of the water outlet part, and the handle 211 of the rotating seat 21 faces the position of the handheld part, when a user holds the handheld part of the water outlet device, the user can still stir the handle 211 by one hand, so that the switching operation of the water outlet function of the water outlet device is very convenient.
In addition, the utility model further provides an embodiment two, which is different from the embodiment one in that a tooth groove 226 is further arranged on the mating surface 222, and a tooth groove protrusion 342 for fitting with the tooth groove 226 is arranged on the positioning protrusion 341.
Specifically, referring to fig. 9 and 10, a plurality of continuous slots 226 are provided between three positioning grooves 223 on the mating surface 222, the depth of each slot 226 is less than that of each positioning groove 223, and the width of each slot 226 is less than that of each positioning groove 223, i.e., the size of each slot 226 is less than that of each positioning groove 223.
A spline protrusion 342 with a size matched with that of the spline 226 is further protruded from the positioning protrusion 341 of the sliding block 34, and the spline protrusion 342 can abut into the spline 226.
As the rotational member rotates, the spline projections 342 will sequentially drop into the splines 226, providing a better rotational feel to the user.
The utility model provides a transmission positioning structure and a water outlet device, wherein the transmission positioning structure is characterized in that a fixed part and an elastic part are arranged on a sliding block 34, so that the sliding block 34 can be used as a component which forms inclined plane fit with a rotating piece and can also be used as a component for providing gear feeling, an elastic pin is not required to be arranged, the complexity of the whole structure is reduced, the structure of the water outlet device adopting the transmission positioning structure is simpler, and the manufacturing and maintenance costs are reduced.
The description of the above specification and examples is intended to be illustrative of the scope of the present invention and is not intended to be limiting. Modifications, equivalents and other improvements which may occur to those skilled in the art and which may be made to the embodiments of the utility model or portions thereof through a reasonable analysis, inference or limited experimentation, in light of the common general knowledge, the common general knowledge in the art and/or the prior art, are intended to be within the scope of the utility model.
