Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

Example 1: referring to fig. 1 to 3, in this embodiment, when it is desired to open the water valve to allow water to enter the cartridge. The user only needs to press the button on the outer side wall of the shell, the button can push the first sliding block to slide in the first accommodating cavity towards the direction of the first spring, and the first spring is extruded. At this time, the first base located in the first accommodating cavity does not displace, and the water valve rotationally connected to the first base through the first rotating shaft does not displace transversely at this time. When the first sliding block slides towards the first spring direction, the first control unit positioned in the first groove of the first sliding block can slide towards the third rotating shaft direction, the shifting claw which is originally embedded between the ratchet structures on the outer side wall of the third rotating shaft at one end can push the ratchet structures to move towards the direction of the first spring, and the third rotating shaft can rotate circumferentially on the first base at the moment. At the moment, the second arc-shaped guide surface is attached to the first arc-shaped guide surface. When the third rotating shaft rotates in the circumferential direction, the columnar protrusions on the upper end face of the third rotating shaft rotate in the circumferential direction along with the third rotating shaft, and at the moment, the first gap between the two columnar protrusions is communicated with the water outlet. After water enters the first accommodating cavity from the water inlet on the outer side wall of the shell, the water can enter the water outlet from the first gap. At this time, when the user releases the pressed button, the first sliding block slides in a direction away from the third rotating shaft under the pushing of the first spring. The second arc-shaped guide surface of the shifting claw can slide towards the direction of the second groove between the ratchet structures along the first guide arc surface of the outer side wall of each ratchet structure until the end part of the shifting claw, which is far away from one end of the columnar rotating block, is embedded into the second groove. Because the second spring is arranged between the left side of the second limiting protrusion and the inner side wall of the left side of the first groove, when the pusher dog slides to the second groove, the second spring can push the second limiting protrusion to slide to the right side of the columnar rotating block, the opposite pusher dog can rotate in the opposite direction along with the rotation of the second limiting protrusion, and the pusher dog can be tightly embedded into the second groove at the moment.

When the water valve needs to be closed and closed, water cannot enter the filter element. The user only needs to press the button of casing lateral wall once more, and the button can push away first sliding block and slide to first spring place direction in first holding intracavity, and first spring receives the extrusion. At this time, the first base located in the first accommodating cavity does not displace, and the water valve rotationally connected to the first base through the first rotating shaft does not displace transversely at this time. When the first sliding block slides towards the first spring direction, the first control unit positioned in the first groove of the first sliding block can slide towards the third rotating shaft direction, the shifting claw which is originally embedded between the ratchet structures on the outer side wall of the third rotating shaft at one end can push the ratchet structures to move towards the direction of the first spring, and the third rotating shaft can rotate circumferentially on the first base at the moment. At the moment, the second arc-shaped guide surface is attached to the first arc-shaped guide surface. When circumferential direction takes place for the third pivot, the column arch of third pivot up end just can follow third pivot circumferential direction, and the column arch just can rotate the position at first clearance place before to again, and the delivery port offsets with the protruding lateral wall of column this moment, and the column arch has just also accomplished closing to the delivery port. After water enters the first accommodating cavity from the water inlet on the outer side wall of the shell, the water can enter the water outlet from the first gap. At this time, when the user releases the pressed button, the first sliding block slides in a direction away from the third rotating shaft under the pushing of the first spring. The second arc-shaped guide surface of the shifting claw can slide towards the direction of the second groove between the ratchet structures along the first guide arc surface of the outer side wall of each ratchet structure until the end part of the shifting claw, which is far away from one end of the columnar rotating block, is embedded into the second groove. Because the second spring is arranged between the left side of the second limiting protrusion and the inner side wall of the left side of the first groove, when the pusher dog slides to the second groove, the second spring can push the second limiting protrusion to slide to the right side of the columnar rotating block, the opposite pusher dog can rotate in the opposite direction along with the rotation of the second limiting protrusion, and the pusher dog can be tightly embedded into the second groove at the moment.

The invention relates to a waterway control device of a tap water purifier, which comprises a shell 1, wherein the outer side wall of the shell 1 is fixedly connected with a filter element 2, the outer side wall of the shell 1 is provided with a water inlet 3, a first accommodating cavity 4 is arranged in the shell 1, the first accommodating cavity 4 is communicated with the water inlet 3, the inner side wall of the first accommodating cavity 4 is communicated with the filter element 2 through a water outlet 5, a control mechanism 6 for driving the water outlet 5 to be opened or closed is arranged in the first accommodating cavity 4, the control mechanism 6 comprises a first base 7 fixedly connected with the bottom surface of the first accommodating cavity 4, the upper end surface of the first base 7 is slidably connected with a first sliding block 8, a water valve 9 for controlling the water outlet 5 to be opened or closed is arranged above the first sliding block 8, the lower end surface of the water valve 9 is provided with a first rotating shaft 10, the upper end surface of the first sliding block 8 is provided with a first groove 11, the bottom surface of the first, first pivot 10 rotates after passing first through-hole 12 to be connected in first base 7 up end, first recess 11 bottom surface is equipped with second pivot 13, 13 lateral walls of second pivot rotate and are connected with control water valve 9 pivoted first the control unit 14, 1 lateral wall of casing is equipped with the second through-hole of the first holding chamber 4 of intercommunication, sliding connection has button 16 in the second through-hole, button 16 keeps away from second through-hole one side and 8 lateral walls fixed connection of first sliding block, 16 one end lateral walls of button are kept away from to first sliding block 8 and pass through the first holding chamber 4 inside walls of first spring 17 elastic connection.

In this technical scheme, the user only need through the button of pressing the casing lateral wall alright take place the circumferential direction through the water valve of the horizontal slip drive first holding intracavity of first sliding block, and then makes the water valve open or close the delivery port. Compared with the traditional knob type water valve, the button type water valve switch in the technical scheme is simpler, more convenient and more labor-saving. In this embodiment, the first through hole has a long shape, so that the first slide block can slide laterally outside the first rotation shaft even if the first rotation shaft located in the first through hole is not displaced.

As a preference: the upper end face of the first base 7 is provided with a third through hole 18 through which the first rotating shaft 10 can be inserted and can rotate circumferentially, the water valve 9 comprises a third rotating shaft 19 arranged above the first sliding block 8, the lower end face of the third rotating shaft 19 is fixedly connected with the first rotating shaft 10, one end of the first rotating shaft 10, which is far away from the third rotating shaft 19, penetrates through the first through hole 12 in the bottom face of the first groove 11 and then is inserted into the third through hole 18, a plurality of ratchet structures 20 are arranged on the outer side wall of the third rotating shaft 19 at circumferential intervals, a first arc-shaped guide surface 21 which can be matched with the first control unit 14 is arranged on the outer side wall of each ratchet structure 20, a plurality of columnar protrusions 22 are fixedly connected on the upper end face of the third rotating shaft 19 at circumferential intervals, and a first gap 23 through which water can flow enters. In the scheme, after the first rotating shaft at the lower end of the water valve is inserted into the third through hole, the water valve can be ensured not to horizontally displace but only to circumferentially rotate in the process of transverse sliding of the first sliding block. In this scheme, the ratchet structure arranged on the outer side wall of the third rotating shaft in the circumferential direction is the same as the ratchet gear structure commonly found in the current market.

In this technical scheme, be located the third pivot lateral wall between ratchet structure and the columnar protrusion and be equipped with a sealing washer, the effect of this sealing washer lies in preventing the sealing washer of the water entering first sliding block department between the columnar protrusion.

As a preference: the first control unit 14 includes a cylindrical rotating block 24 sleeved on the outer side wall of the second rotating shaft 13, the cylindrical rotating block 24 is close to a second limiting protrusion 25 fixedly connected to the outer side wall of one side of the button 16, the outer side wall of the second limiting protrusion 25 is elastically connected to the inner side wall of the first groove 11 through a second spring 26, the cylindrical rotating block 24 is close to a pusher dog 27 fixedly connected to the outer side wall of one side of the third rotating shaft 19, and the end portion of the pusher dog 27 close to one end of the third rotating shaft 19 is abutted to the outer side wall of one side of the pusher dog 27 close to the ratchet. In this scheme, the lateral wall of column turning block is the spacing arch of fixedly connected with second and pusher dog respectively, and the spacing arch of second and pusher dog all are located the right side of column turning block, and the spacing bellied left side lateral wall of second passes through second spring and first recess left side inside wall elastic connection. Under a normal state, the second spring pushes the second limiting protrusion to slide towards the inner side wall of the right side of the first groove, and the shifting claw on one side, far away from the second limiting protrusion, of the opposite columnar rotating block can slide towards the direction of the third rotating shaft due to the displacement of the second limiting protrusion until the second arc-shaped guide surface of the shifting claw is attached to the first arc-shaped guide surface of the ratchet structure or the shifting claw is embedded into the second groove between the two ratchet structures. Such a design ensures that when the finger slides towards the first spring, the finger can give sufficient pushing force to the second groove and the ratchet structure to further drive the third shaft to rotate axially. When the shifting claw slides towards the direction departing from the first spring, the shifting claw slides into the second groove between the two ratchet structures along the first arc-shaped guide surface on the outer side wall of the ratchet structures. In the process that the pusher dog slides back to the second groove, the third rotating shaft does not rotate circumferentially because the third rotating shaft is not subjected to any jacking force.

In this technical solution: the push rod is internally provided with a shifting fork, the function is to enable the rotary switching shaft to keep unidirectional rotation, the working mode is to push the push rod, the push rod drives the shifting fork to jack the ratchet on the outer side wall of the third rotating shaft, and the cylindrical rotating block is far away from the second spring on the outer side wall of the second limiting bulge on one side of the shifting claw to ensure that the shifting claw has a force towards the axis. And the third rotating shaft rotates by 60 degrees by the pushing of the pusher dog. Releasing the button, the first spring will eject the first slider to reset. At the moment, the pusher dog slides out along the first arc-shaped guide surface on the outer side wall of the ratchet, so that the third rotating shaft cannot be driven to rotate.

As a preference: second spring 26 is fixedly connected to the outer side wall of the left side of second limiting protrusion 25, second spring 26 is far away from the inner side wall of the left side of first groove 11 fixedly connected to one end of second limiting protrusion 25, third rotating shaft 19 is located on the left side of pusher dog 27, the outer side wall of the left side of pusher dog 27 is provided with a second arc-shaped guide surface 28 which facilitates sliding of first arc-shaped guide surface 21, six ratchet structures 20 are circumferentially arranged on the outer side wall of third rotating shaft 19, and a second groove 29 which enables the pusher dog 27 to be close to the end portion of one end of third rotating shaft 19 to be embedded is arranged between each ratchet structure 20.

As a preference: three columnar protrusions 22 are circumferentially arranged on the upper end face of the third rotating shaft 19 at intervals, and a first gap 23 is formed between each columnar protrusion 22. Namely, when the third rotating shaft rotates by 60 degrees, the first gap is aligned to the water outlet on the side wall of the first accommodating cavity. When the third rotating shaft rotates circumferentially for 60 degrees, a water outlet on the inner side wall of the first accommodating cavity is communicated with the first gap, and water enters the water outlet from the first gap; or the water outlet is blocked by the columnar bulge, and water in the first accommodating cavity cannot enter the water outlet.
