As a preferred embodiment, a filter screen 16 is disposed on the valve core body 1 at the water inlet 11 to filter impurities in the water.
The working process of the structure is as follows:
as shown in fig. 15 and 16, when the key pawl column 21 is pressed, the guide block 223 on the pawl shaft 22 slides into the deep tooth groove 43, at this time, the first water passing hole 01 between the upper water outlet section 101 and the water inlet section 102 is opened, the first water outlet 13 discharges water, at this time, the flow rate adjusting member 4 is rotated counterclockwise, as shown in fig. 17 and 18, the flow rate adjusting member 4 drives the key pawl column 21 to rotate, thereby driving the rotating body 34 to rotate, the rotating body 34 rotates relative to the limiting member 33, and the rotation is converted into downward axial displacement of the switching shaft 3 relative to the valve core body 1, the upper section 321 of the valve body 32 approaches the first water passing hole 01, so that the water passing amount of the first water passing hole 01 becomes small, thereby the water discharging amount of the first water outlet 13 becomes small, and conversely, the flow rate adjusting member 4 is rotated clockwise, thereby the water discharging amount of the first water outlet 13 becomes large. When the rib 45 on the surface of the flow regulating member 4 abuts against the first limiting plate 51, the water output of the first water outlet 13 is at the maximum.
As shown in fig. 19 and 20, when the flow rate adjusting member 4 is rotated counterclockwise continuously, so that the right side of the rib 45 abuts against the second limiting piece 52, the upper section 321 of the valve body 32 blocks the first water passing hole 01, at this time, the first water outlet 13 and the second water outlet 14 do not discharge water, and the valve core is in a closed state. At this time, as shown in fig. 21 and 22, if the key pawl column 21 is pressed and released, the guide block 223 on the pawl shaft 22 slides into the shallow tooth groove 44 under the action of the spring 24 and the pawl reset seat 23, at this time, the second water through hole 02 between the lower water outlet section 103 and the water inlet section 102 is opened, the second water outlet 14 is discharged, when the water quantity needs to be adjusted, as shown in fig. 23 and fig. 24, the flow rate adjusting member 4 is rotated counterclockwise, the flow rate adjusting member 4 drives the key pawl column 21 to rotate, thereby driving the rotating body 34 to rotate, the rotating body 34 rotates relative to the limiting member 33, and the rotation is converted into the downward axial displacement of the switching shaft 3 relative to the valve core body 1, the lower section 323 of the valve body 32 moves in the direction away from the second water passing hole 02, so that the water passing amount of the second water passing hole 02 is increased, when the right side of the rib 45 on the surface of the flow regulating member 4 abuts against the second limiting piece 51, the water passing amount of the second water passing hole 02 is the largest. On the contrary, if the flow rate adjusting member 4 is rotated clockwise, the water output of the second water outlet 14 becomes smaller, and when the flow rate adjusting member 4 is further rotated until the left side of the rib 45 on the surface of the flow rate adjusting member abuts against the stopper 51, the valve core is closed, as shown in fig. 25 and 26.
In the above process, the position where the guide block 223 on the ratchet shaft 22 is in the deep spline 43 and the right side of the rib 45 on the surface of the flow rate adjusting member 4 is not abutted against the second stopper piece 52 is regarded as the first position, and the position where the guide block 223 on the ratchet shaft 22 is in the shallow spline 44 and the left side of the rib 45 on the surface of the flow rate adjusting member 4 is not abutted against the stopper piece 51 is regarded as the second position.
The above embodiments are only for illustrating the technical idea of the present invention, and the protection scope of the present invention is not limited thereby, and any modifications and equivalents made on the basis of the technical idea of the present invention fall within the protection scope of the present invention.
