Referring to fig. 3 to 4, a plurality of switching columns 1711 are fixedly disposed on the switching valve rod 171, a top end of each switching column 1711 has a switching inclined plane 1713, a plurality of switching grooves 117 are formed on an inner peripheral wall of the water passing body 110, and each switching groove 117 has an accommodating inclined plane 1171 matched with the switching inclined plane 1713. The heights of the accommodating inclined planes 1171 relative to the bottom cover 130 are sequentially increased, and the switching valve rod 171 can be driven by the switching push rod 150 to rotate, so that the switching column 1711 sequentially extends into the plurality of switching grooves 117. The convex hull plug 173 synchronously changes the water passing areas of the water inlet 113 and the water outlet 115 under the drive of the switching valve rod 171 so as to control the water passing flow. Specifically, each switching column 1711 can be propped in one of the switching slots 117 and can switch between different switching slots 117 under the driving of the switching push rod 150, so that the height of the switching valve rod 171 changes and the convex hull plug 173 is driven to move in the vertical direction.

The inner peripheral wall of the water passing body 110 is provided with a positioning rib (not shown) parallel to the extending direction of the switching push rod 150, the switching push rod 150 can slide along the positioning rib, the bottom of the switching push rod 150 is provided with a plurality of inclined tooth surfaces 153, and the inclined tooth surfaces 153 are matched with the switching inclined surfaces 1713 so as to drive the switching valve rod 171 to rotate when the switching push rod 150 slides along the positioning rib. Specifically, the bottom of the switching pushrod 150 is serrated with a plurality of adjacent beveled teeth.
In the present embodiment, the width of the switching slant face 1713 is larger than the width of the accommodating slant face 1171, so that when the switching column 1711 is propped in the switching groove 117, the switching column 1711 can still be propped against the switching column 1711 by the bevel face 153 at the bottom of the switching push rod 150 and drive the switching column 1711 to shift in the horizontal direction, and finally drive the switching valve rod 171 to rotate.
In this embodiment, the switching bevel 1713 of the switching post 1711, the bevel tooth surface 153 at the bottom of the switching push rod 150, and the accommodating bevel 1171 in the switching groove 117 have a certain matching relationship, which is specifically as follows: when the switch post 1711 is held against the switch slot 117, the switch ramp 1713 engages with the receiving ramp 1171, and the top edge of the switch ramp 1713 coincides with the top edge of the receiving ramp 1171, such that the top edge of the switch ramp 1713 is vertically aligned with the centerline of the corresponding bevel gear 153. When the switching push rod 150 moves downward to contact with the switching post 1711, the top edge of the switching bevel 1713 coincides with the middle line of the corresponding bevel gear surface 153, so that the switching post 1711 deflects in the horizontal direction under the abutting of the bevel gear, so that the top edge of the switching bevel 1713 coincides with the top edge of the bevel gear surface 153, after that, the switching push rod 150 moves upward, the switching post 1711 abuts again in the switching post 1711, and since the switching post 1711 deflects in the horizontal direction, the switching post 1711 abuts again in the other switching groove 117 when abutting again, and the top edge of the switching bevel 1713 is opposite to the middle line position of the accommodating bevel 1171 of the switching groove 117 and continues to move under the spring force to abut against the top edge of the accommodating bevel 1171, and abuts again in the switching groove 117.
In this embodiment, the switching valve rod 171 includes a bearing base and a connecting rod, the connecting rod is fixedly connected to the bearing base, the switching column 1711 is fixedly connected to the bearing base, and the connecting rod extends into the sliding slot 151.
Referring to fig. 5, a plurality of convex hulls 1731 and a plurality of water passing grooves 1733 are provided on the outer circumferential surface of the convex hull plug 173, and the plurality of convex hulls 1731 and the plurality of water passing grooves 1733 are staggered for water passing and pressure relief.
In the present embodiment, the extending direction of each convex hull 1731 is consistent with the extending direction of each concave groove, and is parallel to the extending direction of the connecting rod. When the convex hull plug 173 completely blocks the plurality of water outlets 115 and the water inlets 113, the key switching flow controller 100 is in a dripping state, and water is discharged and pressure is released through the plurality of water discharge grooves 1733, so as to ensure that the switching valve rod 171 is not blocked due to excessive back pressure in the water discharge cavity 111. Meanwhile, the convex hull 1731 can also reduce the friction between the convex hull plug 173 and the inner wall of the water body 110.
In summary, the key switching flow controller 100 provided by the present invention has the following working principle: by pressing the switching push rod 150 to press the switching valve rod 171, the switching push rod 150 moves downwards along the positioning rib on the water passing body 110, and meanwhile, the switching push rod 150 drives the switching column 1711 to deflect in the horizontal direction through the plurality of oblique tooth surfaces 153, so that the switching valve rod 171 is driven to rotate, the switching inclined planes 1713 of the switching column 1711 are propped against the accommodating inclined planes 1171 in different switching grooves 117, and the areas of the water inlet 113 and the water outlet 115 blocked by the convex hull plug 173 below the switching valve rod 171 are different due to the fact that the heights of each accommodating inclined plane 1171 are inconsistent with each other relative to the bottom cover 130, so that the water passing area is controlled, and the purpose of controlling the water passing amount is achieved. When the reset is needed, the switching valve rod 171 is continuously pressed down by pressing the switching push rod 150, the switching push rod 150 drives the switching valve rod 171 to rotate, the switching inclined surface 1713 of the switching column 1711 is propped against the inclined tooth surface 153 under the action of the elasticity of the compression spring, and meanwhile, the convex hull plugs 173 are positioned above the plurality of water outlets 115 and the water inlets 113 to restore to the original water passing area. Compared with the prior art, the key switching flow controller 100 provided by the invention realizes the control of the water flow by pressing the switching push rod 150, is convenient to operate and accurate to control, and can well control the water flow very conveniently.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
