The specific meaning of the above terms in the present invention can be understood in specific cases to those of ordinary skill in the art.

The following examples are given to illustrate the present invention.

As shown in fig. 1 to 5, a push-button switching valve of the present invention is characterized by comprising: the body 10 is provided with a water inlet 11, a first water inlet hole 141, a second water inlet hole 142, a first water outlet 151 and a second water outlet 152, wherein the first water inlet hole 141 is communicated with the water inlet 11 and the first water outlet 151, the second water inlet hole 142 is communicated with the water inlet 11 and the second water outlet 152, and the first water inlet hole 141 and the second water inlet hole 142 are oppositely arranged;

a sealing plate 30 acting between said first inlet hole 141 and said second inlet hole 142, said sealing plate 30 having a discrete stable position;

a step-by-step advancing device configured to move said sealing sheet 30 stepwise between stable positions;

an actuation device for the step-by-step advancing device, comprising a button 21, said button 21 being configured to move the sealing sheet 30;

wherein the discrete stable positions are two positions, namely: the sealing plate 30 is tightly attached to block the first water inlet hole 141, and the sealing plate 30 is tightly attached to block the second water inlet hole 142.

It should be noted that, in this embodiment, the first water inlet 141 and the second water inlet 142 are oppositely disposed, and the distance between the first water inlet 141 and the second water inlet 142 is small, so that the sealing piece 30 in the middle is moved to easily block and seal the first water inlet 141 or the second water inlet 142, and in the switching process, the acting force on the sealing piece 30 may be small because: the sealing plate 30 has a certain flexibility, when a force F is applied to its side (as shown in fig. 6), its side close to the water inlet hole is slightly peeled off, so that a gap is generated between it and the water inlet hole, so that water flow can enter the back pressure side from the pressure-bearing side through the gap, thereby reducing the pressure difference between the pressure-bearing surface P1 and the back pressure surface P0, and thus the sealing plate 30 can be pushed to move to the other side with a small force.

In this embodiment, the step-by-step propulsion device is configured to make the sealing sheet 30 translate back and forth between the first water inlet hole 141 and the second water inlet hole 142 by the operation of the button 21. Such as an intermittent pressing structure of an automatic ball pen or a mechanical card slot structure of a mobile phone memory card (as shown in fig. 7), the structure can realize the reciprocating motion of high and low positions.

In this embodiment, the body 10 is provided with a through hole 16 penetrating left and right, a movable cavity 14 communicating with the water inlet 11 is provided in the middle of the through hole 16, the movable cavity 14 is flat, the left plane of the movable cavity and the through hole 16 form the first water inlet 141, the right plane of the movable cavity and the through hole 16 form the second water inlet 142, the sealing sheet 30 translates in the movable cavity 14, two ends of the through hole 16 are sealed by rubber balls 17, and a water through hole 161 communicating the first water outlet and the second water outlet is provided in the middle.

In this embodiment, the body 10 is provided with an actuating chamber 12, the step-by-step propulsion device is arranged in the actuating chamber 12, and the acting point of the step-by-step propulsion device acting on the sealing sheet 30 is outside the hole wall of the through hole 16. It is apparent that the further apart the force points are, the less force is pushing sealing disc 30.

In this embodiment, flexible sealing materials (for example, two-shot soft plastic) are disposed on two side surfaces of the sealing sheet 30. Therefore, the plugging reliability of the sealing sheet 30 can be improved, and the soft glue can be arranged on two side surfaces of the movable cavity 14 to cover the periphery of the water inlet hole, but the process is not easy to achieve, and the soft glue is arranged on the sealing sheet 30 more easily.

In this embodiment, the step-by-step propulsion device includes: the automatic intermittent ball pen pressing mechanism comprises an actuating piece 22, a driven piece 23, a base 13 and a spring 25, wherein a first ratchet 131 is arranged on the base 13, a second ratchet 221 is arranged on the actuating piece 22, a third ratchet 231 is arranged on the driven piece 23, the first ratchet 131, the second ratchet 221 and the third ratchet 231 are matched with each other to form an automatic intermittent ball pen pressing structure, a fixing rod 24 is arranged on the driven piece 23, a sealing piece 30 is arranged on the fixing rod 24 in a sliding mode, and the spring 25 provides restoring elastic force for the fixing rod 24.

It should be noted that the sealing plate 30 slightly slides on the fixing rod 24, and is provided for reliability, that is, the driven member 23 jumps during the whole movement process, and is not precisely located at a predetermined position (a high position and a low position of the reciprocating movement), but when the driven member 23 moves to the high position or the low position, the sealing plate 30 may adaptively block the first water inlet 141 or the second water inlet 142 under the action of water pressure.

In this embodiment, the base 13 is detachably and fixedly disposed in the actuation chamber 12. This is provided to facilitate the fixing of the sealing ring between the bottom surface of the base 13 and the bottom surface of the actuation chamber 12.

In this embodiment, the body 10 is cylindrical, the upper end of the body is the water inlet 11, the actuating chamber 12 is below the water inlet 11, and the actuating chamber 12 is configured to: a counter bore with an opening at the left side is arranged along the diameter direction of the body 10, a cover 40 is fixedly and hermetically arranged at the opening, and the spring 25 is pre-tightened between the cover 40 and the fixing rod 24.

In this embodiment, the shower head is sequentially provided with an upper housing 50, a lower housing 60, a decoration cover 70 and a water outlet cover 80 from top to bottom, a filter element 90 is arranged in the upper housing 50, the button switching valve as claimed in claims 1 to 8 is arranged in the lower housing 60, a through hole 61 is arranged on the side of the lower housing 60, and the button 21 is in sliding fit with the through hole 61.
