Angle 144, chamfering 144 can provide resigning and guide space, and water retaining wall 22, sealing ring rub with switching 15 inner wall of pipe in reduction
It wipes, to extend service life of the invention；Switch the seperated design of pipe 15 simultaneously more convenient for designing on mold, producing
Angle 144.
For the state for preferably judging mixing water outlet, let the user know that middle water retaining wall 22 is moved into water inlet 141
Between left wall and right wall, the present invention is equipped with mounting groove 24 on changer lever 2, cooperates finite place piece 4, mounting groove 24 in mounting groove 24
Elastic component 5 is combined between locating part 4, which is spring；In first embodiment, switching 14 inner wall of chamber is equipped with for limit
The limiting slot 145 of position 4 end activity of part cooperation；In second embodiment, switching 15 inner wall of pipe is equipped with matches for 4 end activity of locating part
The limiting slot 145 of conjunction.Above-mentioned limiting slot 145 is arc groove, facilitates 4 end of locating part mobile.Above-mentioned limiting slot 145 and water inlet
The distance of 141 middle lines of mouth is equal to 24 center of mounting groove at a distance from middle 22 middle line of water retaining wall, i.e., middle water retaining wall 22 is moved into water
When among the left wall and right wall of mouth 141,4 end of locating part cooperates in limiting slot 145, and generating resistance to remind user currently is
Mix the state of water outlet.
Above-mentioned 1 outer wall of tee tube is fixed with the socket 6 for shower suspension.
Above structure is simple, is readily produced, fashionable different from the design of existing knob switching valve；Pass through shifting
Dynamic 2 waterway switching of changer lever, only water retaining wall, sealing ring can generate a degree of abrasion in use, even if damage, after
Phase maintenance cost is low；Compared to the structure of knob switching valve, occur that a possibility that damaged is lower, and the service life is longer；
Structure of the invention is compact to design, takes up space smaller；User is realized in tee tube 1 by the light mobile handoff bar of pressing keys 3
The switching in water route, to meet different bathing demands.
Above-described embodiment and schema and non-limiting product form and style of the invention, any technical field it is common
The appropriate changes or modifications that technical staff does it all should be regarded as not departing from patent category of the invention.
