By moving the switching lever 2, the position of the switching lever 2 in the switching cavity 14 is changed, and the purpose of switching waterways is achieved.
For conveniently pressing and moving the switching rod 2, the user experience is improved, keys 3 are fixed at two ends of the switching rod 2, and the keys 3 are movably arranged at the end parts of the switching cavity 14 in a penetrating mode. The key 3 includes a left key 31 and a right key 32, which are respectively screwed to the left end and the right end of the switching lever 2. When the left button 31 is pressed, the switching rod 2 moves rightwards, and the water outlet state of the invention sequentially switches the water outlet of the second water outlet pipe, the mixed water outlet and the water outlet of the first water outlet pipe; when the right button 32 is pressed, the opposite of the left button 31 is performed.
In order to limit the movable range of the key 3 at the end of the switching cavity 14, a switching tube 15 is formed in the switching cavity 14, the switching rod 2 is movably inserted into the switching tube 15, and the key 3 is movably matched with the end of the switching tube 15. The water inlet 141, the left water outlet 142 and the right water outlet 143 are all provided on the switching pipe 15. The length of the switching rod 2 is longer than that of the switching tube 15, and the difference between the lengths is the distance between the right wall of the left water outlet 142 and the left wall of the right water outlet 143; the end of the switching tube 15 is shorter than the end of the switching cavity 14, and the distance between the two is equal to the thickness of the top surface of the key 3, so that when the key 3 is embedded into the end of the switching cavity 14 and abuts against the end of the switching tube 15, the outer surface of the key 3 is flush with the end of the switching cavity 14.
A second embodiment of the present invention is shown in fig. 7 and 8, which is different from the first embodiment in that: the switching tube 15 includes an inner core 16 movably fitted in the switching chamber 14, the switching tube 15 is divided into the inner core 16 from a side wall of the water inlet 141, and the right water outlet 143 is provided in the inner core 16. The inner core 16 is movably secured to the inner wall of the switching chamber 14 in a threaded manner. The joint of the two walls of the water inlet 141 and the inner cavity of the switching tube 15 is provided with a chamfer 144 for the movable fit of the sealing ring, the chamfer 144 can provide a yielding and guiding space, and the friction between the middle water retaining wall 22, the sealing ring and the inner wall of the switching tube 15 is reduced, so that the service life of the invention is prolonged; while the split design of the switching tube 15 facilitates the design and production of the chamfer 144 on the die.
In order to better judge the mixed water outlet state, a user knows that the middle water retaining wall 22 is moved between the left wall and the right wall of the water inlet 141, the switching rod 2 is provided with the mounting groove 24, the mounting groove 24 is matched with the limiting piece 4, the elastic piece 5 is matched between the mounting groove 24 and the limiting piece 4, and the elastic piece 5 is a spring; in the first embodiment, the inner wall of the switching cavity 14 is provided with a limiting groove 145 for the movable fit of the end part of the limiting piece 4; in the second embodiment, the inner wall of the switching tube 15 is provided with a limiting groove 145 for the movable fit of the end of the limiting member 4. The limiting groove 145 is an arc-shaped groove, so that the end part of the limiting piece 4 can conveniently move. The distance between the limiting groove 145 and the center line of the water inlet 141 is equal to the distance between the center of the mounting groove 24 and the center line of the middle water retaining wall 22, that is, when the middle water retaining wall 22 moves to the middle between the left wall and the right wall of the water inlet 141, the end of the limiting piece 4 is matched in the limiting groove 145, so as to generate resistance to remind the user of the current mixed water outlet state.
The outer wall of the tee pipe 1 is fixed with a socket 6 for hanging the shower head.
The structure is simple, the production is easy, and the design is novel unlike the design of the existing knob type switching valve; the waterway is switched by moving the switching rod 2, only the water retaining wall and the sealing ring can generate a certain degree of abrasion in the use process, and even if the waterway is damaged, the later maintenance cost is low; compared with the structure of a knob type switching valve, the structure has lower possibility of breakage and longer service life; the invention has compact structural design and smaller occupied space; the user easily removes the selector lever through pressing button 3, realizes the switching of the interior water route of three-way pipe 1 to satisfy different bathing demands.
