And when the water is shut down, the state is unique, the mode which is frequently used by the user is convenient for the next use, and the switching operation is reduced. Because be the shutoff second delivery port 153 all the time at the beginning, the contained angle of first clearance 33 and second clearance 43 line is the obtuse angle, and this contained angle is gradually big at the switching process, consequently can be more and more laborsaving at the in-process of pressing operating parts 3, facilitate the use, and when the chamber 15 of crossing water is not crossed, switching piece 2 automatic re-setting is to shutoff second delivery port 153, need not the user and press again, even switch to the in-process of shutoff second delivery port 153 by shutoff first delivery port 152, need bigger hard, this power also is provided by piece 5 that resets, need not the user and operate, or during the operation, owing to have piece 5 that resets and act on more laborsavingly.

This mode has changed the sliding direction of switching piece 2 through driving medium 4 to make body 1 can be littleer in radial ascending size, when being applied to the gondola water faucet, enable the radial size of handle littleer, more convenient the holding.

Example two:

referring to fig. 11 and 12, in the first state, α 1 is 83.87 °, β 1 is 17.26 °, γ 1 is 93.50 °, h1 is 3.2, and d1 is 3.06; in the second state, α 2 is 107.22 °, β 2 is 8.92 °, γ 1 is 108.5 °, and d1 is 0.91, so that during the process from the first state to the second state, the operating element 3 rotates clockwise by 8.34 °, the transmission element 4 rotates counterclockwise by 15 °, and the switching shaft slides by 2.15. In this way, since α 1 is acute angle, i.e. less than 90 °, the pressing process can be pressed more easily with the increase of α 1 angle, but in the first half stroke, the pressing force is relatively heavy until α 1 crosses the right-angle inflection point of 90 °, which causes a setback at the initial operation, so that the user can clearly sense the switching operation (similar to the function of hitting the ball in place), and a slamming sound is generated when pressing at 90 ° this inflection point, in this way, the pressing distance of the operating element 3 is short relative to that of the first embodiment, the part of the outer surface of the operating element 3 body 1 is not very large, and is more beautiful, but the force is more prominent than the corresponding force.

According to the first and second embodiments, the moment arm is larger and more labor-saving as the first gap 33 gets closer to the right end, i.e., farther from the first axis, and is also related to the inclination angle of the first gap 33, the distance between the connection point of the transmission member 4 and the switching member 2 and the second axis in the second direction, and the position of the force receiving portion 41 and the first gap 33 according to the lever principle. If the same work is performed (i.e., the distance the switching element 2 moves), it takes a greater amount of effort to save the pressing distance. Conversely, to save effort, the pressing distance needs to be increased appropriately.

Certainly, in other embodiments, in order to make the sliding distance of the switching element 2 larger, the force receiving portion 41, the second axis and the pushing and supporting portion 22 may be sequentially distributed from top to bottom, and the distance between the force receiving portion 41 and the second axis is smaller than the distance between the pushing and supporting portion 22 and the second axis.

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 invention 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 invention.
