Specifically, as shown in fig. 3, in the initial position, the handle 311 is in the vertical position, a cavity is formed in the handle 311, the protection handle 420 is located in the cavity, two ends of the protection handle penetrate through the cavity, the upper end of the protection handle is the pressing position, the lower end of the protection handle is connected with the limiting part 430, namely a limiting rod, the limiting rod is transversely arranged and is detachably connected with the protection handle 420, the limiting rod is located in the cavity of the housing, it can be seen that a first elastic member 440, namely a spring, is installed around the protection handle 420, referring to fig. 4, an arc-shaped notch is formed on the upper edge of the right side of the first housing 100, the arc-shaped notch has an arc angle of 120 degrees, in other embodiments, the notch can also be 100 degrees, 145 degrees, 135 degrees, 90 degrees, 105 degrees and the like, and is the limiting rail 410, in the initial position, the limiting rod is located in the middle position of the arc rail, and can freely move in the arc degree of the arc rail, at this time, the valve core 200 is controlled by the connecting rod to be in a first state, so that warm water mixed with cold water and hot water flows out of the first water outlet passage 122, the left and right directions rotate to regulate the flow of the cold water and hot water at the input end of the valve core 200, so as to change the temperature of the warm water within a certain temperature threshold, after the protection handle 420 is pressed, the protection handle 420 drives the limiting rod to move downwards, at this time, in a state of closing the child lock, the diameter of the moving circumferential track of the limiting rod is smaller than that of the circumference of the limiting track 410 when the limiting rod moves, the first elastic member 440 gives a force to the limiting rod to return to the circumference of the limiting track 410, when the moving radian is larger than that of the limiting track 410, the right side wall of the first shell 100 plays a role of blocking, the limiting rod is prevented from returning to the circumference of the limiting track 410, and at this time, the valve core 200 is matched with the valve core 200 to reach a second state, at this time, the water outlet end of the valve core 200 is connected with the second water outlet passage 123, heating or cooling to certain temperature to rivers through outside temperature control spare, under general conditions, the temperature at this moment is at 70-98 degrees centigrade, or at 1-10 degrees centigrade, be unsuitable for children's contact, in addition, refer to fig. 4, this internal supplementary slide rail 312 that has of second casing 310, supplementary slide rail 312 has a vertical groove, the one end of gag lever post is located this inslot, and then when guaranteeing that its removal track is certain, prevent that it from receiving the unilateral moment of torsion, reduce its cracked risk, increase its life.

Example 2:

because the valve core 200 is different, in order to enter the first state, the handle 311 needs to be moved to the right by a certain angle (taking the view angle of fig. 3 as an example) and rotate clockwise or counterclockwise along the rotation direction thereof, so that the valve core 200 is in the first state, and at the same time, warm water flows out, it should be noted that this embodiment is consistent with the above structure, so the limiting rod is limited by the limiting track 410, and can still only move within 120 ° of the limiting track 410, and generally rotate simultaneously in the left and right direction, i.e. has an effective rotation direction of 60 °, unlike that, when the handle 311 does not move outward, i.e. rotate clockwise or counterclockwise in the vertical state, it is within the arc of the limiting track 410 and does not flow out, this way makes a difference point between the normal use of warm water and the use of warm/cold water at constant temperature be added, and has better identification, is more favorable for preventing the baby from being scalded due to misoperation.

In addition, in some embodiments, the waterway circulation chamber 120 further includes a closed chamber formed in the first housing 100, as shown in fig. 3, and the lower side of the closed chamber has threads to facilitate installation of the filtering apparatus in the closed chamber.

Example 3:

different from the embodiment 1 and the embodiment 2, on the basis of the embodiment 1 or the embodiment 2, the reset assembly 500 further includes a reset plate 500, the reset assembly 500 includes a fixed plate 510, a movable plate 520, a second elastic member 530 and a reset plate 540, the fixed plate 510, the movable plate 520, the second elastic member 530 and the reset plate 540 are disposed in the accommodating chamber 110, the reset plate 540 is movably connected to the connecting portion 320, the connecting portion 320 can drive the reset plate 540 to rotate when rotating, the second elastic member 530 connects the fixed plate 510 and the movable plate 520, and when or after the valve core 200 is in the second state, the reset plate 540 drives the movable plate 520 to move relative to the fixed plate 510 when rotating, so as to change the elastic potential energy of the second elastic member 530.

That is to say, after the radian of the displacement of the limiting rod driven by the second housing 310 is greater than the unidirectional radian of the limiting rail 410, since the connecting rod drives the reset plate 540 to rotate at the same time, after the radian is greater than the above, the reset plate 540 drives the movable plate 520 to rotate, and at this time, the position of the fixed plate 510 is fixed, so as to change the shape of the second elastic member 530, thereby obtaining the elastic potential energy for resetting, that is, when the unidirectional rotation of the second housing 310 is greater than 60 °, the second housing 310 obtains a reset elastic potential energy, so that it automatically returns after being released.

The reset plate 540 is formed with a driving tooth 541, the movable plate 520 is formed with a driven tooth 521, and when the valve core 200 is in the second state or after the second state, the driving tooth 541 drives the driven tooth 521 to make a circular motion so as to drive the movable plate 520 to rotate. That is to say, there is an interval driving structure between the reset plate 540 and the movable plate 520, the reset plate 540 drives the movable plate 520 to be close to the driven teeth 521 on one side of the reset plate 540 through the driving teeth 541 close to the movable plate 520, it should be noted that, in the initial state, the driving teeth 541 and the driven teeth 521 are not adjacently disposed, and they are an interval uniform arrangement structure, specifically, as shown in fig. 6, 3 driving teeth 541 are disposed on the periphery of the reset plate 540 with the circle center thereof being a circular array of dots, 3 driven teeth 521 are disposed on the inner side of the movable plate 520 with the circle center thereof being a circular array of dots, and in the initial state, every two adjacent driving teeth 541 and driven teeth 521 are spaced by 60 °.
