As the level of living of people increases, people increasingly seek a healthy and high quality living experience, with particular attention being paid to the quality of water. In daily life, the water directly drunk is required to be sterile and harmless, so that a high-specification water purifier is required to be used; but other water uses are also ensured to be clean and safe, such as cooking, dish washing, washing and the like, and a more convenient water purifier is needed. The tap type water purifier is a miniature water purifier which can be directly installed and hung on a tap, can directly filter water in a pipeline, has the advantages of clean and safe water outlet, rich mineral substances, high flow rate and the like, and is widely applied to family life.
Generally, the existing tap water purifier mainly comprises two components, namely a switching mechanism and a filtering device, wherein the switching mechanism is mainly used for changing the water outlet mode and is directly connected with a tap, so that raw water can flow into a flow dividing piece from the tap, flow into the filtering device after being divided by the switching mechanism in the flow dividing piece, or directly flow out from a water outlet. However, the conventional switching mechanism has the following disadvantages: in the operation of cutting water, when the amplitude of rotation of the handle for driving the cutting water is too small, that is, the handle is not driven in place, the phenomenon that purified water and raw water are discharged simultaneously or the water yield is reduced may be caused.
Disclosure of Invention
The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a water cutting device for a faucet-type water purifier, in which a sufficient driving range is required to complete a water cutting operation, and in which the problem of simultaneous water discharge of purified water and raw water does not occur.
The aim of the invention is achieved by the following technical scheme:

the water cutting piece comprises a water sealing part and a plurality of stress driving parts, wherein the water sealing part is used for sealing the raw water inlet or the purified water inlet, and the stress driving parts are uniformly distributed along the circumferential direction and vertically extend downwards; the lower end of the stress driving part is provided with an inclined lifting surface; the top end of the lifting piece is provided with a plurality of lifting parts extending vertically upwards along the circumferential direction, and the lower end of the lifting piece extends to the operating handle of the water purifier;
the limiting piece is of a hollow structure, and a plurality of limiting parts are arranged in the inner hole along the circumferential direction; the clearance between the adjacent limiting parts forms a limiting groove, the lifting part and the stress driving part extend into the limiting groove, and the lifting part is positioned right below the stress driving part; the top end of the limiting part is provided with an inclined rotating guide surface, and the inclination directions of the adjacent rotating guide surfaces and the lifting surface are the same;
the lower end of the compression spring is abutted against the rotating center of the water sealing part, and when the water cutting piece moves upwards, the compression spring is compressed and applies a downward driving force to the water cutting piece.
The water cutting principle of the water cutting device is as follows:
generally, the water cutting operation piece of the water purifier is an operation handle, and when the water outlet mode of the water purifier needs to be switched, the operation handle is rotated, so that the driving end of the operation handle drives the lifting piece upwards; specifically, as the lifting part of the lifting piece and the force-bearing driving part of the water cutting piece are both positioned in the limiting groove and the lifting part is positioned below the force-bearing driving part, when the lifting piece moves upwards, the lifting part can prop against the lifting surface of the force-bearing driving part; the lifting surface is inclined, so that the acting force of the lifting part on the force-bearing driving part is perpendicular to the lifting surface and obliquely upwards towards the force-bearing driving part according to force-bearing analysis, and the lifting surface can be decomposed into a vertical component force upwards vertically and a horizontal component force horizontally towards the force-bearing driving part; however, due to the limitation of the limiting groove, the front-stage forced driving part can only vertically move upwards.
Until the height of the part of the stressed driving part at the lowest end exceeds the height of the part at the uppermost end of the limiting part, at the moment, the stressed driving part is not limited by the limiting groove in the horizontal direction, but still receives downward pressure of the compression spring, so that the lifting part moves upwards along the inclined lifting surface relatively along with the continuous lifting of the lifting piece, and the stressed driving part is driven to move in the horizontal direction; further, the force-bearing driving parts and the lifting parts are all multiple and are uniformly distributed along the circumferential direction, so that the water cutting piece can rotate on the horizontal plane. Along with the upward movement of the lifting piece, the stress driving part of the water cutting piece rotates to the rotation guide surface of the limiting part from the limiting groove, and as the top end of the limiting part of the limiting piece is provided with the inclined rotation guide surface, the inclination directions of the adjacent rotation guide surfaces and the lifting surface are the same, and under the action of the compression spring, the stress driving part moves downwards to the next limiting groove along the rotation guide surface, so that the water sealing part is switched between the raw water inlet and the purified water inlet.
Therefore, in the water cutting process, if the driving amplitude of the operating handle is too small, the stress driving part only moves upwards in the limiting groove and does not pass through the limiting part to rotate on the horizontal plane, so that the water sealing part cannot be driven to rotate.
In a preferred embodiment of the invention, the lifting part has a triangular shape, and the top is provided with a circular arc sliding surface acting on the lifting surface. Through setting up the circular arc sliding surface for lifting portion can be more smooth and easy upwards remove along the lifting surface, drive atress drive portion simultaneously and remove towards the horizontal direction.

Through the structure, the water sealing part can rotate around the rotating fixing piece under the drive of the forced driving part, so that the raw water inlet and the purified water inlet are switched.
The water cutting mechanism is arranged between the water inlet piece and the flow dividing piece; the upper end of the compression spring is abutted against the water inlet piece, and the lower end of the compression spring is abutted against the rotating center of the water sealing part. Raw water flows into the flow dividing piece from the water inlet piece, and flows into the filtering device or directly flows out under the switching of the water cutting mechanism.

the raw water inlet is communicated with the raw water outlet, and the purified water inlet is communicated with the purified water transition port. When the raw water flows in from the raw water inlet, the raw water directly flows out from the raw water outlet; when raw water flows in from the purified water inlet, the raw water flows into the filter element from the purified water transition port, and flows out from the purified water outlet of the filter element after being filtered.
According to a preferred scheme of the invention, the limit part, the stress driving part and the lifting part are four; the number of the water sealing parts is two, and the water sealing parts are symmetrically arranged at 180 degrees;
the phase difference angle of the raw water inlet and the purified water inlet is 90 degrees. Every time the water sealing part is driven once, the stress driving part rotates from the last limit groove to the next limit groove with the phase difference of 90 degrees, and simultaneously the water sealing part also rotates by 90 degrees, so that the water sealing part is switched between the raw water inlet and the purified water inlet; in this way, in continuous water cutting, the forced driving part always rotates along the limit groove in a unidirectional circulation manner, and meanwhile, the water sealing part rotates alternately between the raw water inlet and the purified water inlet in a continuous circulation manner.

Referring to fig. 5-6, the lifting portion 2-1 has a triangular shape, and the top portion is provided with an arc sliding surface acting on the lifting surface 1-21. By arranging the arc sliding surface, the lifting part 2-1 can move upwards along the lifting surface 1-21 more smoothly, and meanwhile, the forced driving part 1-2 is driven to move horizontally.
Referring to fig. 5-6, a rotation fixing member 6 is provided between the compression spring 4 and the water cutting member 1, the rotation fixing member 6 includes a rotation fixing portion 6-1 and a mounting portion 6-2 fixedly provided on the rotation fixing portion 6-1; the rotation fixing part 6-1 is arranged in a matching groove positioned in the rotation center on the water sealing part 1-1; one end of the compression spring 4 surrounds the mounting part 6-2 and abuts against the rotation fixing part 6-1. With the above structure, the water sealing part 1-1 can rotate around the rotation fixing member 6 under the drive of the force-driven part 1-2, thereby switching between the raw water inlet 8-1 and the purified water inlet 8-2.
Referring to fig. 6-9, the limit part 3-1, the force-bearing driving part 1-2 and the lifting part 2-1 are four; the number of the water sealing parts 1-1 is two, and the water sealing parts are symmetrically arranged at 180 degrees; the phase difference angle of the raw water inlet 8-1 and the purified water inlet 8-2 is 90 degrees.

The lower end of the water sealing part 1-1 is provided with a mounting groove, and a sealing gasket 9 is arranged in the mounting groove.
Referring to fig. 3, the diverter 8 is provided with a mounting hole 10 for mounting the limiting member 3, and the lower end of the lifting member 2 extends downward to the operating handle 5.
Referring to fig. 1 to 9, the water cutting device in this embodiment has the following working principle:
generally, the water cutting operation piece of the water purifier is an operation handle 5, and when the water outlet mode of the water purifier needs to be switched, the operation handle 5 is rotated, so that the driving end of the operation handle 5 drives the lifting piece 2 upwards; specifically, since the lifting part 2-1 of the lifting element 2 and the force-receiving driving part 1-2 of the water cutting element 1 are both positioned in the limit groove 3-2, and the lifting part 2-1 is positioned below the force-receiving driving part 1-2, when the lifting element 2 moves upwards, the lifting part 2-1 will be propped against the lifting surface 1-21 of the force-receiving driving part 1-2; the lifting surface 1-21 is inclined, so that according to stress analysis, the acting force of the lifting part 2-1 on the stress driving part 1-2 is perpendicular to the lifting surface 1-21 and obliquely upwards towards the stress driving part 1-2, and can be decomposed into a vertical component force upwards vertically and a horizontal component force towards the stress driving part 1-2 horizontally; however, due to the limitation of the limiting groove 3-2, the front-stage forced driving part 1-2 can only move vertically upwards.
Until the height of the part of the force-bearing driving part 1-2 at the lowest end exceeds the height of the part of the limit part 3-1 at the uppermost end, at this time, the force-bearing driving part 1-2 is not limited by the limit groove 3-2 in the horizontal direction, but still receives the downward pressure of the compression spring 4, so as to continue to lift the lifting piece 2 upwards, relatively, the lifting part 2-1 moves upwards along the inclined lifting surface 1-21, so as to drive the force-bearing driving part 1-2 to move in the horizontal direction; further, the force-bearing driving parts 1-2 and the lifting parts 2-1 are all multiple and are uniformly distributed along the circumferential direction, so that the water cutting piece 1 can rotate on the horizontal plane. Along with the upward movement of the lifting piece 2, the force-bearing driving part 1-2 of the water cutting piece 1 rotates from the limiting groove 3-2 to the rotating guide surface 3-11 of the limiting part 3-1, and as the inclined rotating guide surface 3-11 is arranged at the top end of the limiting part 3-1 of the limiting piece 3, the inclination directions of the adjacent rotating guide surfaces 3-11 and the lifting surface 1-21 are the same, and then under the action of the compression spring 4, the force-bearing driving part 1-2 moves downwards into the next limiting groove 3-2 along the rotating guide surface 3-11, so that the water sealing part 1-1 is switched between the raw water inlet 8-1 and the purified water inlet 8-2.
Therefore, in the water cutting process, if the driving amplitude of the operation handle 5 is too small, the force-bearing driving part 1-2 only moves upwards in the limit groove 3-2 and does not rotate on the horizontal plane beyond the limit part 3-1, so that the water sealing part 1-1 cannot be driven to rotate, when the operation handle 5 is driven off, the force-bearing driving part 1-2 moves downwards along the limit groove 3-2 under the action of the compression spring 4, and the water sealing part 1-1 is reset along with the reset, so that the water sealing position is unchanged, namely the water discharging mode is unchanged.
The foregoing is illustrative of the present invention, and is not to be construed as limiting thereof, but rather as various changes, modifications, substitutions, combinations, and simplifications which may be made without departing from the spirit and principles of the invention are intended to be included within the scope of the invention.
