DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0031] Please refer to Figures 1-11 In the embodiments of the utility model, a manual water-saving valve comprises an upper shell 1 and a lower shell 2 connected with each other, the upper shell 1 and the lower shell 2 are connected with each other to form a cylindrical water storage cavity, the top of the upper shell 1 is provided with a water inlet 3, the water inlet 3 is connected with a faucet, and water enters the water storage cavity of the upper shell 1 and the lower shell 2 through the water inlet 3;

[0032] The bottom of the lower housing 2 is provided with an opening, and a piston rod 5 that matches the size of the opening is installed in the opening. One end of the piston rod 5 located outside the lower housing 2 is connected to the base 4. The piston rod 5 is a hollow rod. Several protruding drain outlets 502 are provided on the side wall of the rod body 501 of the piston rod 5, preferably four in a semi-circular shape. The lower end of the rod body 501 is open and connected to the water outlet 6 on the base 4.

[0033] like Figures 5-7 As shown, a baffle 8 and a diaphragm 7 are installed on the upper end of the piston rod 5. The diaphragm 7 is made of rubber. The baffle 8 is located on the upper end of the diaphragm 7, and a guide block 802 is also provided at the edge of its disc block 801. Preferably, there are two guide blocks 802 arranged symmetrically. The inner cavity of the upper housing 1 is provided with a sliding groove 10 that matches the guide block 802. The vertical projection of the baffle 8 is located within the vertical projection of the diaphragm 7. The highest point of the sliding groove 10 is lower than the upper inner wall of the upper housing 1, so that when the baffle 8 is at the highest point, there is still a certain water inlet space between it and the upper inner wall of the upper housing 1.

[0034] like Figure 11 , Figure 4 The lower housing 2 is provided with a base 11 that cooperates with the protruding drain outlet 502, which serves to limit, seal, and stop water. The base 11 is a concave groove.

[0035] The piston rod 5 has several upwardly protruding mounting posts 503 on its top body 501. Mounting holes 803 matching the mounting posts are pre-drilled on both the baffle 8 and the diaphragm 7. The baffle 8 and the diaphragm 7 are mounted on the rod 501 through the mounting holes 803 and the mounting posts 503. The baffle 8 and the diaphragm 7 are also provided with locking holes 804, which are locked in place by screws installed in the locking holes 804. Preferably, there are four mounting posts 503 and four mounting holes 803, and one locking hole 804 located at the center of the cross-section.

[0036] Furthermore, in order to lock the piston rod 5 at its maximum upward stroke position and achieve continuous water output, the upper housing 1 is provided with a locking groove 9 connecting the sliding groove 10. The locking groove 9 is perpendicular to the sliding groove 10, and is located in the middle of the inner cavity of the upper housing 1, allowing the baffle 8 to rotate 45 degrees. Figure 6 As described above, when the baffle 8 rotates 45 degrees, the guide block 802 of the baffle 8 disengages from the sliding groove 10, thereby fixing the vertical position of the baffle 8 and locking the piston rod 5. After rotating 45 degrees counterclockwise, the guide block 802 of the baffle 8 returns to the sliding groove 10, restoring the vertical movement of the baffle 8 and the piston rod 5.

[0037] The four protruding mounting columns 503 of the top end of the piston rod 5 serve to fix the baffle 8 and the diaphragm 7, and are fixed by cooperating with the locking holes 804 and screws in the top during installation, and when the piston rod 5 and the baffle 8 are twisted left and right during the long water lock dead action, the top screw is prone to loosening and falling off over a long time, and the force is directly applied on the four protruding columns when twisted left and right, so that the phenomenon of loosening and falling off of the fixed screw due to long time action is prevented.

[0038] The working principle of the utility model is:

[0039] When the manual water-saving valve is used, the water inlet 3 of the upper shell 1 is connected with a faucet;

[0040] In the initial state, the bottom support 4 and the piston rod 5 are in a drooping state under the action of water pressure, the diaphragm 7 at the upper end of the piston rod 5 is pressed on the semicircular base in the lower shell 2, the drain outlet 502 of the piston rod 5 is isolated from the water storage cavity between the upper shell 1 and the lower shell 2, the drain channel is closed, and the water is stopped;

[0041] When water is needed, the bottom support 4 is lifted, at this time, the drain outlet 502 of the piston rod 5 is communicated with the water storage cavity between the upper shell 1 and the lower shell 2, the water in the water storage cavity enters the hollow piston rod 5 through the semicircular drain outlet 502 at the top of the piston rod 5, and flows out through the connecting water outlet 6 at the lower end, the water flowing out effect is synchronized with the action of lifting the bottom support 4, the water is discharged as needed, the hand is away from the bottom support, the water flow is stopped instantaneously, the water-saving purpose is achieved, and the operation is simple, and meanwhile, the waste caused by continuous water flow is avoided;

[0042] When continuous water is needed, the piston rod 5 is pushed to the maximum stroke, the baffle 8 is rotated by 45 degrees, the guide block 802 of the baffle 8 is separated from the sliding groove 10 in the up-down direction on the inner wall of the upper shell, is matched with the horizontal locking groove 9, the vertical position of the baffle 8 is fixed, the locking of the piston rod 5 is completed, and the continuous water demand of the manual water-saving valve is realized.

[0043] The manual water-saving valve is simple in structure and convenient to operate, realizes water saving at low cost, and is convenient for popularization.
