Detailed Description

In order to make the technical problems, technical schemes and beneficial effects to be solved more clear and obvious, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Referring to fig. 1 to 6, an improved switching mechanism includes a waterway switching assembly 10, a switching driving assembly 20 and a reset driving assembly 30, wherein the switching driving assembly 20 includes a switching push rod 21, and the reset driving assembly 30 includes a reset push rod 31. In addition, the waterway switching assembly 10 includes a fluted disc 11, specifically, two layers of evenly distributed teeth are disposed on the periphery of the fluted disc 11, and the teeth are: the switching teeth 111 located in the extending direction of the switching push rod 21 may implement the switching of the waterway, and the reset teeth 112 located in the extending direction of the reset push rod 31 may implement the reset switching of the waterway, and optionally, the switching teeth 111 are located on the upper layer of the reset teeth 112.

Specifically, when water appears in the water-passing state, the switching push rod 21 moves towards the fluted disc 11 and finally abuts against the switching teeth 111 to push the fluted disc 11 to rotate, so that waterway switching is realized, and the sprinkler or top spraying is switched from an initial waterway state to another waterway state; at the same time, the reset push rod 31 moves away from the fluted disc 11, and does not contact the reset teeth 112.

When the water pressure disappears in the water stop state, the switching push rod 21 is separated from the switching teeth 111 and is far away from the fluted disc 11, and meanwhile, the reset push rod 31 moves towards the fluted disc 11 and finally abuts against the reset teeth 112 to push the fluted disc 11 to rotate, so that the waterway is switched again, and the waterway is restored to the original waterway state.

In a preferred embodiment, the switching driving assembly 20 includes a switching cylinder 22, a switching stopper 23 and a switching spring 24, wherein one end of the switching cylinder 22 is mounted on the outer periphery of the shower or the top-spraying water channel (not shown), and an aperture 221 is further formed on the outer wall of the switching cylinder 22 so as to be ventilated with the outside. The switching block 23 is disposed at one end of the switching cylinder 22 away from the waterway switching assembly 10, wherein a sealing ring is disposed between the switching block 23 and the switching cylinder 22 to prevent water seepage therebetween. The switching push rod 21 is sleeved with a switching spring 24 at the periphery and is slidably mounted in the switching cylinder 22, wherein one end of the switching push rod 21 faces the fluted disc 11, and the other end faces the switching stop block 23.

Specifically, as shown in fig. 5, the switching push rod 21 has a cavity structure, and a water passing cavity 211 is formed in the switching push rod, wherein a water inlet 2111 is formed at one end of the water passing cavity 211 close to a water inlet channel (not shown), and a water outlet 2112 is formed at one end of the water passing cavity close to the switching stop block 23; the switch block 23 extends out of a protruding block 231 towards the direction of the switch push rod 21, and when the switch push rod 21 slides in the switch cylinder 22, the protruding block 231 can be inserted into the water outlet 2112 so as to realize movement positioning of the switch push rod 21. In addition, the end of the switching push rod 21 facing the fluted disc 11 is an arc-shaped top end so as to adapt to the circular motion of the switching teeth 111 in the pushed state.

Further, a sealing groove 212 is further provided on the outer periphery of the switching push rod 21, and a Y-shaped sealing ring 25 is installed in the sealing groove 212 to seal the switching push rod 21 and the switching cylinder 22, thereby concentrating water flow, maintaining water pressure, and pushing the switching push rod to move.

In addition, a sealing ring is also arranged between the switching push rod 21 and the switching cylinder 22 near one side of the waterway switching assembly 10 so as to prevent water seepage between the switching push rod 21 and the switching cylinder.

The specific working mode of the improved switching mechanism is as follows:

when water is introduced, as shown in fig. 3 to 4, external water flows into the water inlet 2111 through a water inlet channel (not shown), then flows into the water passing cavity 211, flows out of the water outlet 2112 into the switching cylinder 22, and due to the sealing and water-blocking effect of the Y-shaped sealing ring 25, the water flow pushes the switching push rod 21 to slide towards the fluted disc 11 in the switching cylinder 22, meanwhile, air in the switching cylinder 22 is discharged through the hole 221, the switching push rod 21 finally abuts against the switching teeth 111 to push the fluted disc 11 to rotate, and then the waterway switching is realized, wherein the switching spring 24 is clamped by the two-way clamping of the outer walls of the switching cylinder 22 and the sealing groove 212 on the switching push rod 21, and compression deformation is accumulated, and rebound force is accumulated; at the same time, the reset pushrod 31 moves away from the toothed disc 11 under water pressure.

When water is stopped, as shown in fig. 1 to 2, the water pressure disappears, the water flow does not apply pressure to the switching push rod 21, at this time, the switching spring 24 with a repulsive force pushes the outer wall of the sealing groove 212, so that the switching push rod 21 does not contact the fluted disc 11 any more, but moves away from the fluted disc 11 towards the switching stop 23 to return to the initial state, meanwhile, the reset push rod 31 moves towards the fluted disc 11 under no water pressure, and then abuts against the reset teeth 112 to push the reset teeth 112 to move, so that the waterway returns to the initial waterway state.

According to the utility model, the two push rods always do not contact the fluted disc 11 at the same time by arranging the movement directions of the switching push rod 21 and the reset push rod 31 opposite to each other, so that the switching push rod 21 is not contacted with the fluted disc 11 when the reset push rod 31 is switched, the friction resistance of the reset push rod 31 is reduced, the output switching force is reduced, the reset switching action of the reset push rod 31 can be easily and smoothly completed, and the reset push rod has the advantages of exquisite structure and stable function.

While the utility model has been described above with reference to the accompanying drawings, it will be apparent that the utility model is not limited to the above embodiments, but is capable of being modified or applied directly to other applications without modification, as long as various insubstantial modifications of the method concept and technical solution of the utility model are adopted, all within the scope of the utility model.
