When the utility model is assembled, the external thread 181 of the outer shell 18 is used to screw into the internal thread of a common faucet, so that the user can easily install the utility model.

When the utility model is used, it can be divided into four states: before boiling water, after boiling water, increasing the water flow and closing the water flow. The following describes the action of the internal structure of the utility model in detail for the four states.

Please refer to Fig. 4, under the first state (before boiling water), this state is that the user has not yet opened the water tap, and there is no water inside the utility model; under this state, the first elastic element 61 pushes up the positioning ball ring 50, and the positioning ball ring 50 is closely attached to the bottom surface of the positioning ball upper cover 30, further closing the through hole 32 and the water stop valve 80 arranged inside the through hole 32; at the same time, the second elastic The element 62 pushes down against the baffle plate 63, so that the baffle plate 63 closes the fifth water hole 14, and successively makes the actuating rod 40 lean against downwards. In this state, the upward actuation of the actuating rod 40 The part 41 will be located at the place where the actuating space 91 communicates with the transverse channel 92. In other words, the upper actuating part 41 will abut against the positioning ball 70 in the lateral direction, and at this time, the positioning ball ring will be pushed by the first elastic element 61. 50 pushes upwards, and the positioning ball 70 abuts upwards against the positioning ball ring.

Please refer to Fig. 5, in the second state (after boiling water), this state is the situation where the user turns on the faucet but has not yet pushed the button part 631; The first water flow hole 31, the second water flow hole 21 and the third water flow hole 13 flow downwards, which is the case of a small amount of water; at the same time, due to the push of the water flow, all the through holes 32 are arranged The water stop valve 80 will be tightly pressed downward against the through hole 32 and the positioning ball ring 50, so the fourth water flow hole 81 on the water stop valve 80 is still closed; in addition, the positioning ball ring 50 will be lowered. Closely lean against the positioning ball 70, and because the positioning ball 70 is equivalent to the positioning ball ring 50 and the upper actuating part 41 of the actuator 40 is engaged in the transverse channel 92, the positioning ball ring The position of 50 is also fixed and cannot be lowered, and the positioning ball ring 50 will not be separated from the water stop valve 80 due to the excessive impact force of the water flow, causing the fourth water hole 81 to appear in a state of flow, and due to flow resistance The disc 63 also tightly closes the fifth water flow hole 14, so the water flow in this state is small.

Please refer to Fig. 6, under the third state (increased water flow), this state is that after the user pushes the button part 631 upwards, all the through holes that were originally closed are opened, and the water flow is therefore increased to a large amount of water; First, the user pushes the button part 631 upwards, so that the upper actuating part 41 of the actuating rod 40 leaves the position where it abuts against the positioning ball 70, and moves upward to a part closer to the top of the actuating space 91. At this time, Because the outer diameter of the lower actuating part 42 is smaller than the outer diameter of the upper actuating part 41, the positioning ball 70 can move closer to the center of the transverse channel 92, so that the bottom of the positioning ball ring 50 is no longer covered by the positioning ball 70. At this time, the positioning ball ring 50, multiple positioning balls 70 and the lower actuating part 42 present a relationship of leaning against each other from the outside to the inside, and the positioning balls 70 are stuck at this time. In the place where the transverse channel 92 is adjacent to the actuating space 91, precisely, the position of the positioning ball 70 is below the upper actuating part 41, so that the upper actuating part 41 cannot move downward and is fixed in the actuating space 91 and due to the lowering of the positioning ball ring 50, the fourth flow holes 81 of the plurality of water stop valves 80 are changed from a closed state to a flow state. In addition, because the button part 631 pushes upwards, causing The baffle plate 63 no longer closes the fifth water hole 14; at this time, the water flow can also pass through the fourth water hole 81, The path from the second flow hole 21 to the third flow hole 13 is discharged, and the holes that the base 10 can flow out of are also increased from the original third flow hole 13 to the third flow hole 13 and the fifth flow hole 14, so the utility model The flowable holes above and below increase, and the amount of outflowing water increases, achieving the effect of increasing the water flow.

Please refer to Fig. 4 and Fig. 6, under the fourth state (closing the water flow), this state is the situation after the user closes the water tap after passing through the third state; No longer being pushed downward by the water flow, the first elastic element 61 pushes upward against the positioning ball ring 50 to return to the position in the first state and resumes abutting against the bottom surface of the positioning ball upper cover 30 to close the through hole 32 and the water stop valve 80; at the same time, the positioning ball ring 50 rises and no longer abuts the positioning ball 70, and when the second elastic element 62 pushes against the baffle plate 63 downward, since the positioning ball 70 can move toward The direction of the positioning ball ring 50 is fixed, and it no longer engages the upper actuating part 41, so the actuating rod 40 is pushed down by the second elastic element 62, and returns to the position of the first state, and the positioning ball 70 is also Because the inclined portion 43 is pushed out laterally, it pushes up against the bottom of the positioning ball ring 50 , and the baffle plate 63 also re-closes the fifth water flow hole 14 to achieve the effect of returning to the first state.

The utility model utilizes a plurality of elastic elements and the engagement relationship between the positioning ball 70 and the surrounding elements, so that the utility model not only has the effect of saving water, but also has the function of automatically returning to the original position after adjusting the water volume, which is convenient for the user to get off. The function of not having to manually adjust the water volume before one use.
