The switching disc 42 can be rotated intermittently in one direction by pressing the button 41, so that the ratchet 421 slides into the vertical through groove or is abutted against the limiting block 31; when the ratchet 421 slides into the vertical through slot, the center bolt 2 is located at the first position; when the ratchet 421 abuts against the stopper 31, the center pin 2 is located at the second position.
As shown in fig. 5 to 7, the water outlet 13 may include a necking section 131 and a flaring section 132; the lower end of the necking section 131 is connected with the upper end of the flaring section 132, the aperture of the necking section 131 is smaller than that of the flaring section 132, and the aperture of the mounting port 11 is larger than that of the necking section 131; when the central bolt 2 is positioned at the first position, the lower plug 22 is in sealing fit with the necking section 131 to close the water outlet 13; when the center bolt 2 is positioned at the second position, the lower plug 22 is positioned in the flaring section 132 and is separated from sealing fit with the necking section 131 so as to open the water outlet 13; because the aperture of the mounting port 11 is larger than that of the necking segment 131, when the lower plug 22 closes the water outlet 13, the upward acting force generated by the water flow in the valve body 1 of the upper plug 21 is larger than the downward acting force generated by the water flow in the valve body 1 of the lower plug 22, so that the central plug 2 has a tendency of upward movement, when the water outlet 13 is closed, the central plug 2 can be prevented from downward movement due to overlarge water flow pressure in the valve body 1, so that the lower plug 22 is separated from sealing fit with the necking segment 131 to open the water outlet 13, and water leakage is caused; it should be noted that, the aperture of the mounting opening 11 may be slightly larger than the aperture of the necking segment 131, so that the difference between the upward acting force generated by the water flow in the valve body 1 on the upper plug 21 and the downward acting force generated by the water flow in the valve body 1 on the lower plug 22 is small, and the pressing force of the pressing step type pressing mechanism 4 is not greatly different, so that the pressing hand feel is hardly affected by the fluctuation of the water pressure. In order to ensure that the upper plug 12 and the mounting opening 11 can be completely in sealing fit, an upper ring groove 211 is formed on the periphery of the upper plug 21, and an upper sealing ring 212 is matched in the upper ring groove 211. In order to ensure that the lower plug 22 can be completely sealed when in sealing fit with the necking section 131, a lower annular groove 221 is formed at the periphery of the lower plug 22, and a lower sealing ring 222 is matched in the lower annular groove 221; the inner wall of the flaring section 132 may be provided with a plurality of inwardly protruding blocking pieces 1321, a water passing gap is formed between each blocking piece 1321 for passing water, and the minimum distance between the inner end of the blocking piece 1321 and the outer periphery of the lower plug 22 is smaller than the line diameter of the lower sealing ring 222, so that when the central plug 2 is in the second position to open the water outlet 13, the blocking piece 1321 can limit the lower sealing ring 122 to prevent the lower sealing ring 222 from being separated from the lower ring groove 221 due to the water flow; in addition, when the center bolt 2 is located at the second position, the lower sealing ring 222 is located in the flared section 132, and a gap exists between the lower sealing ring 222 and the inner end of each blocking piece 1321, so that the blocking pieces 1321 and the lower sealing ring 222 can be prevented from generating friction to affect the up-and-down movement of the center bolt 2.
In order to facilitate understanding of the present invention, the working principle of the present invention is explained as follows:
in the initial state, the ratchet 421 slides into the vertical through groove, the center bolt 2 is located at the first position, the lower plug 22 is in sealing fit with the necking section 131 to close the water outlet 13, and the water outlet 13 is in a closed state, so that no water is discharged.
With reference to fig. 5 to 7, when the water outlet 13 is in a closed state, the button 41 is pressed to move the button 41 downwards, the button 41 drives the switching plate 42 to move downwards to enable the ratchet 421 to slide out of the vertical through groove, at this time, under the action of the return spring 43, the ratchet 421 slides relative to the saw tooth 412 to enable the switching plate 42 to rotate relative to the button 41 to a position where the ratchet 421 is aligned with the limiting block 31, and then the pressing of the button 41 is released, under the action of the return spring 43, the switching plate 42 and the central plug 2 move upwards to enable the ratchet 421 of the switching plate 42 to abut against the limiting block 31, at this time, the central plug 2 is in the second position, the lower plug 22 is located in the flaring section 132 and is separated from being in sealing fit with the necking section 131 to open the water outlet 13, and the water outlet 13 is in an open state.
When the water outlet 13 is in an open state, the knob 3 drives the center bolt 2 to rotate by rotating the knob 3, so that the superposition area of the flow regulating block 23 and the water inlet 12 is controlled, and the water passing area of the water inlet 12 is further controlled to realize flow regulation.
With reference to fig. 5 to 7, when the water outlet 13 is in an open state, the button 41 is pressed to move the button 41 downward, the button 41 drives the switching plate 42 to move downward to disengage the ratchet 421 from the stopper 31, and under the action of the return spring 43, the ratchet 421 slides relative to the saw tooth 412 to rotate the switching plate 42 relative to the button 41 to a position where the ratchet 421 is aligned with the vertical through slot, after which the pressing of the button 41 is released, under the action of the return spring 43, the switching plate 42 and the center plug 2 move upward to slide the ratchet 421 of the switching plate 42 into the vertical through slot, and at this time, the center plug 2 is in the first position, the lower plug 22 is in sealing engagement with the necking segment 131 to close the water outlet 13, and the water outlet 13 is in a closed state.
In summary, the present invention can drive the driving center bolt 2 to switch between the first position and the second position by pressing the stepping pressing mechanism 4, thereby controlling the opening and closing of the water outlet 13 to control whether the present invention is used conveniently; in addition, the flow regulating block 23 of the center bolt 2 and the water inlet 12 can be controlled to overlap by rotating the knob 3, so that the water passing area of the water inlet 12 is controlled to realize flow regulation.
The above examples and drawings are not intended to limit the form or form of the present invention, and any suitable variations or modifications thereof by those skilled in the art should be construed as not departing from the scope of the present invention.
