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 tap water purifier has the following disadvantages:
1. in the water switching process, the handle needs to be operated in the corresponding direction, so that the handle drives the switching mechanism in the diverter, and the water switching action is completed; the two water outlet modes correspond to the two positions of the handle, when water cutting operation is carried out, the handle can be operated in the accurate direction, and meanwhile, the handle can be changed back and forth at two different positions, so that the operation is not simple and convenient, and inconvenient operation and primary use are not facilitated.
2. When the amplitude of the rotation of the handle for driving the water cutting is too small, that is, the handle is not driven in place, a phenomenon that purified water and raw water are discharged simultaneously or the water yield is reduced may be caused.
Disclosure of Invention
The invention aims to overcome the problems, and provides a tap type water purifier, wherein an operating handle in the water purifier can be automatically reset after water cutting is finished, two different water outlet modes can be switched by driving the operating handle in the same direction, and in the water cutting process, the water cutting operation can be finished only by enough driving amplitude, so that the problems of water purification, raw water simultaneous water outlet and the like can not occur.
The aim of the invention is achieved by the following technical scheme:
a tap type water purifier comprises a shell, a filtering device, a water cutting device and a water cutting driving mechanism, wherein the filtering device, the water cutting device and the water cutting driving mechanism are arranged in the shell;

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 driving mechanism comprises an operating handle, a fixing piece and an elastic resetting piece; wherein the fixing piece is fixedly arranged in the shell; the operating handle comprises an operating end and a driving end, the operating end extends to the outer side of the shell, and the driving end penetrates through the fixing piece and extends into the flow dividing piece; one end of the elastic resetting piece is fixed on the operation end of the operation handle, and the other end of the elastic resetting piece is fixed on the fixing piece; when the operating handle rotates in the water cutting direction, the elastic reset piece stores energy; when the water cutting operation is completed, the elastic reset piece releases potential energy to drive the operation handle to reset.
The working principle of the tap type water purifier is as follows:
generally, raw water flows from a water inlet to a flow dividing member, flows from a raw water inlet to a raw water outlet under the action of a water cutting member, or flows from a purified water inlet to a purified water inlet channel, flows to a filter element, and flows out after being filtered.
When the water outlet needs to be switched, the operating handle is rotated, the driving end of the operating handle drives the lifting piece to move upwards to switch, and when the operating handle rotates for a certain angle, the water cutting operation is completed, so that the water outlet mode is changed. Specifically, the water cutting process is as follows: because the lifting part of the lifting piece and the stressed driving part of the water cutting piece are both positioned in the limiting groove, and the lifting part is positioned below the stressed driving part, when the lifting piece moves upwards, the lifting part can prop against the lifting surface of the stressed 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, because the limit groove limits the force-bearing driving part in the earlier stage, the force-bearing driving part can only move vertically upwards until the height of the part of the force-bearing driving part at the lowest end exceeds the height of the part of the limit part at the uppermost end, at this time, the force-bearing driving part is not limited by the limit groove and still receives downward pressure of the compression spring in the horizontal direction, so that the lifting part moves upwards along the inclined lifting surface relatively along with the continuous lifting of the lifting part, and the force-bearing driving part is driven to move horizontally; 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, namely the rotating angle 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.
When the operating handle is driven, the operating handle is loosened, and the operating handle is reset under the action of the elastic reset piece, and the principle is as follows: because both ends of the elastic resetting piece are respectively fixed on the operating handle and the fixing piece, the elastic resetting piece is gradually deformed and stores potential energy in the process of cutting water by the operating handle; when the operating handle is released, the elastic reset piece releases potential energy and starts to reset, so that the operating handle is driven to rotate in the direction opposite to the water cutting operation, and the operating handle is driven to reset. Therefore, when water is switched each time, the operating handle is only required to be rotated in the same direction at the same position, and the operation is simple and quick.
According to a preferred scheme of the invention, the filter element cylinder comprises an upper filter element cylinder and a lower filter element cylinder which are connected through a threaded connection structure, wherein the lower filter element cylinder is provided with a connecting arm extending to the flow dividing piece, and a water passing channel communicated with a water purifying and feeding channel is arranged in the connecting arm;

Because the upper filter element cylinder is fixed between the upper shell and the lower shell, and the lower shell is designed as a whole, the filter element can be cleaned or replaced by screwing the upper filter element cylinder and taking the upper filter element cylinder away, and the operation is very convenient.
In a preferred embodiment of the present invention, a rotation display ring which rotates along the water cutting direction is provided between the operation handle and the fixing member; a plurality of marks which are uniformly distributed and used for displaying different water outlet states are arranged on the outer edge surface of the rotary display ring along the circumferential direction;

Generally, when the operating handle rotates in the water cutting direction, the driving hook abuts against the tail end of the ratchet bar, so that the rotating display ring is driven to rotate in the water cutting direction, and the corresponding mark on the rotating display ring rotates to the lower side of the display window, so that a user can observe the mark.
According to a preferred scheme of the invention, a limiting structure for preventing the rotary display ring from reversely rotating is arranged between the rotary display ring and the fixing piece, and comprises a plurality of clamping grooves uniformly distributed along the circumferential direction of the inner wall of the rotary display ring and elastic buckles arranged on the fixing piece;

When the operating handle is loosened, the torsion spring drives the operating handle to reset in the direction opposite to the water cutting direction, wherein, along the direction opposite to the water cutting direction, the elastic buckle of the fixing piece is fixed on the clamping surface, and the driving hook of the operating handle can only drive the rotating display ring to rotate in the water cutting direction, so that the rotating display ring is fixed relative to the fixing piece in the resetting process of the operating handle. The advantage that above-mentioned structure brought is, operating handle is automatic re-setting after accomplishing to cut water, and rotates the demonstration circle and then keep motionless with the mounting after cutting water to can point out the real-time play water mode of user's water purifier.

Through the structure, in the resetting process of the operating handle, under the potential energy drive of the torsion spring, the positioning beads rotate from the last positioning groove to the next positioning groove, and then the operating handle is positioned, so that the operating handle can be positioned at a fixed position after being reset.
Preferably, the number of the positioning beads is two, and the positioning beads are symmetrically arranged in the operation handle. Thus, the operating handle can be more stable in the resetting and rotating process.

According to a preferred scheme of the invention, the ratchet bar and the clamping groove are of arc-shaped structures and are concave inwards; one end of the ratchet strip is fixed on the inner ring of the rotary display ring, and the other end of the ratchet strip extends obliquely inwards; the clamping groove gradually extends from one end provided with the clamping surface to the inner wall of the rotary display ring from the depth to the shallowness. Through the structure, the friction force of the operating handle rotating in the resetting process can be reduced, and the friction force of the rotating display ring rotating in the water cutting process can be reduced, so that the water cutting operation is smoother.

When the raw water flows in from the raw water inlet 8-1a, the raw water directly flows out from the raw water outlet; when raw water flows in from the purified water inlet 8-2a, the raw water flows into the filter element from the purified water transition port 8-3a, and flows out from the purified water outlet of the filter element after being filtered.
Referring to fig. 8-12, the lifting portion 2-1a has a triangular shape, and the top portion is provided with an arc sliding surface acting on the lifting surface 1-21 a. By providing the arc sliding surface, the lifting part 2-1a can move upwards along the lifting surface 1-21a more smoothly, and meanwhile, the force-bearing driving part 1-2a is driven to move horizontally.
Referring to fig. 8-12, a rotation fixing member 6a is provided between the compression spring 4a and the water cutting member 1a, and the rotation fixing member 6a includes a rotation fixing portion 6-1a and a mounting portion 6-2a fixedly provided on the rotation fixing portion 6-1 a; the rotation fixing part 6-1a is arranged in a matching groove positioned in the rotation center on the water sealing part 1-1 a; one end of the compression spring 4a surrounds the mounting portion 6-2a and abuts against the rotation fixing portion 6-1 a. With the above structure, the water sealing part 1-1a can be rotated around the rotation fixing member 6a by the force-driven part 1-2a, thereby switching between the raw water inlet 8-1a and the purified water inlet 8-2 a.
Referring to fig. 8-12, the limit part 3-1a, the force-bearing driving part 1-2a and the lifting part 2-1a are four; the number of the water sealing parts 1-1a is two, and the water sealing parts are symmetrically arranged at 180 degrees; the difference angle between the raw water inlet 8-1a and the purified water inlet 8-2a is 90 degrees. Every time the forced driving part 1-2a rotates from the last limit groove 3-2a to the next limit groove 3-2a with a phase difference of 90 degrees, and meanwhile, the water sealing part 1-1a also rotates by 90 degrees, so that the raw water inlet 8-1a and the purified water inlet 8-2a are converted; in this way, in the continuous water cutting, the force-bearing driving part 1-2a always rotates along the limit groove 3-2a in a unidirectional circulation manner, and meanwhile, the water sealing part 1-1a alternately rotates between the raw water inlet 8-1a and the purified water inlet 8-2a in a continuous circulation manner. The lower end of the water sealing part 1-1a is provided with a mounting groove, and a sealing gasket 9a is arranged in the mounting groove.
Referring to fig. 6, the diverter 8a is provided with a mounting hole 10a for mounting the stopper 3a, and the lower end of the lifter 2a extends downward to the operating handle 1 b.
Referring to fig. 13 to 17, the water cutting driving mechanism includes an operation handle 1b, a fixing member 2b, and an elastic restoring member 3b; wherein the fixing piece 2b is fixedly arranged in the shell through the fixing part 2-1 b; the operating handle 1b comprises an operating end 1-1b and a driving end 1-2b, wherein the operating end 1-1b extends to the outer side of the shell, and the driving end 1-2b extends into the flow dividing piece 8a through the fixing piece 2b; one end of the elastic resetting piece 3b is fixed on the operating end 1-1b of the operating handle 1b, and the other end is fixed on the fixing piece 2 b. The elastic reset piece 3b is a torsion spring, and when the operating handle 1b rotates in the water cutting direction, the torsion spring deforms and stores energy; when the water cutting operation is completed, the torsion spring releases potential energy to drive the operation handle 1b to reset.
Referring to fig. 13-17, a rotary display ring 6b which rotates along the water cutting direction is arranged between the operating handle 1b and the fixed piece 2b; the outer edge surface of the rotary display ring 6b is provided with a plurality of marks which are uniformly distributed along the circumferential direction and used for displaying different water outlet states; the upper shell 1c is provided with a display window 1-1c for observing the marks on the rotary display ring 6 b. Because the operating handle 1b of the water purifier can be automatically reset, a user is difficult to judge the water outlet state from the position of the operating handle 1b, so after the operating handle 1b finishes the water cutting operation, the user can observe the mark on the rotary display ring 6b through the display window 1-1c, thereby judging the water outlet state.
Referring to fig. 13-19, a driving structure for driving the rotary display ring 6b to rotate in the water cutting direction is arranged between the rotary display ring 6b and the operating handle 1b, and the driving structure comprises a plurality of ratchet bars 7b uniformly distributed along the circumferential direction of the inner wall of the rotary display ring 6b and driving hooks 8b arranged on the operating handle 1 b. Generally, when the operation handle 1b rotates in the water cutting direction, the driving hook 8b abuts against the end of the ratchet bar 7b, so that the rotation display ring 6b is driven to rotate in the water cutting direction, and the corresponding mark on the rotation display ring 6b rotates below the display window 1-1c for the user to observe.
Referring to fig. 13-19, a limiting structure for preventing the rotary display ring 6b from rotating reversely is arranged between the rotary display ring 6b and the fixing member 2b, and the limiting structure comprises a plurality of clamping grooves 9b uniformly distributed along the circumferential direction of the inner wall of the rotary display ring 6b and elastic buckles 10b arranged on the fixing member 2b; the clamping groove 9b is internally provided with a clamping surface 9-1b, and when the operating handle 1b resets and rotates, the elastic buckle 10b abuts against the clamping surface 9-1 b.
The principle of operation of the rotary display ring 6b is as follows: since the driving hook 8b of the operation handle 1b abuts against the ratchet 7b of the rotation display ring 6b, the rotation display ring 6b can be rotated with the rotation of the operation handle 1 b; when the operating handle 1b rotates by a certain angle, the water cutting operation is completed, and meanwhile, the elastic buckle 10b on the fixing piece 2b rotates from the last clamping groove 9b to the next clamping groove 9b and abuts against the clamping surface 9-1 b. When the operating handle 1b is released, the torsion spring drives the operating handle 1b to reset in the direction opposite to the water cutting direction, wherein the elastic buckle 10b of the fixing piece 2b is fixed on the clamping surface 9-1b along the direction opposite to the water cutting direction, and the driving hook 8b of the operating handle 1b can only drive the rotating display ring 6b to rotate in the water cutting direction, so that the rotating display ring 6b is fixed relative to the fixing piece 2b in the resetting process of the operating handle 1 b. The advantage that the structure has is that operating handle 1b resets automatically after cutting water, and the rotation display circle 6b is then with mounting 2b still after cutting water is accomplished to can indicate the real-time play water mode of water purifier of user.
Referring to fig. 13-19, a positioning mechanism is arranged between the operating handle 1b and the rotary display ring 6b, and comprises a positioning groove 11b and a positioning bead 12b; the positioning grooves 11b are a plurality of and are uniformly distributed on the inner wall of the rotary display ring 6b along the circumferential direction; the positioning beads 12b are transversely inlaid on the operating handle 1 b. Through the structure, in the resetting process of the operating handle 1b, under the potential energy drive of the torsion spring, the positioning bead 12b rotates from the last positioning groove 11b to the next positioning groove 11b, so that the operating handle 1b is positioned, and the operating handle 1b can be positioned at a fixed position after being reset.
The number of the positioning beads 12b is two, and the positioning beads are symmetrically arranged in the operation handle 1 b. In this way, the operation handle 1b can be made smoother during the reset rotation.
Referring to fig. 13-19, the number of the ratchet 7b, the clamping groove 9b and the positioning groove 11b are equal. The ratchet strip 7b and the clamping groove 9b are of arc-shaped structures and are concave inwards; one end of the ratchet strip 7b is fixed on the inner ring of the rotary display ring 6b, and the other end extends obliquely inwards; the clamping groove 9b gradually extends from the end provided with the clamping surface 9-1b to the inner wall of the rotary display ring 6b from the depth to the shallowness. The friction force of the operating handle 1b rotating in the resetting process and the friction force of the rotating display ring 6b rotating in the water cutting process can be reduced, so that the water cutting operation is smoother.
Referring to fig. 13-14, an operation housing 13b is fixedly arranged at the outer side of the operation end 1-1b, and an operation surface is arranged on the operation housing 13 b. By providing the operation surface, since the shape of the operation surface is different from the shape of the other portion of the operation housing 13b, it is possible to provide a prompt of the operation portion to the user, and to simplify the operation.
Referring to fig. 20-21, the driving end 1-2b is flat and is provided with a long-range driving surface 1-21b and a short-range driving surface 1-22b; when the operating handle 1b is driven for cutting water, the lifting element 2a slides from the short-range driving surface 1-22b to the long-range driving surface 1-21b, rotating around the center.
Referring to fig. 1 to 17, the tap water purifier in this embodiment works as follows:
generally, raw water flows from the water inlet 7a to the flow dividing member 8a, flows from the raw water inlet 8-1a to the raw water outlet by the water cutting member 1a, or flows from the purified water inlet 8-2a to the purified water inlet channel, flows to the filter element, and flows out after being filtered.
When water is required to be switched out, the operating handle 1b is rotated, the driving end 1-2b of the operating handle drives the lifting piece 2a to move upwards to switch, and when the operating handle 1b rotates for a certain angle, water cutting operation is completed, so that the water outlet mode is changed. Specifically, the water cutting process is as follows: because the lifting part 2-1a of the lifting piece 2a and the stressed driving part 1-2a of the water cutting piece 1a are both positioned in the limiting groove 3-2a, and the lifting part 2-1a is positioned below the stressed driving part 1-2a, when the lifting piece 2a moves upwards, the lifting part 2-1a can prop against the lifting surface 1-21a of the stressed driving part 1-2a; wherein, because the lifting surface 1-21a is inclined, according to the stress analysis, the acting force of the lifting part 2-1a to the stress driving part 1-2a is perpendicular to the lifting surface 1-21a and is inclined upwards towards the stress driving part 1-2a, so that the lifting surface can be decomposed into a vertical component force which is vertical upwards and a horizontal component force which is horizontal towards the stress driving part 1-2a; however, because the limit groove 3-2a limits, the front-stage force-bearing driving part 1-2a can only move vertically upwards until the height of the part of the force-bearing driving part 1-2a at the lowest end exceeds the height of the part of the limit part 3-1a at the uppermost end, at this time, in the horizontal direction, the force-bearing driving part 1-2a is not limited by the limit groove 3-2a, but still receives the downward pressure of the compression spring 4a, so as to continue lifting upwards along with the lifting piece 2a, and relatively, the lifting part 2-1a moves upwards along the inclined lifting surface 1-21a, so that the force-bearing driving part 1-2a is driven to move horizontally; further, since the force-bearing driving parts 1-2a and the lifting parts 2-1a are all plural and are uniformly arranged along the circumferential direction, the rotation of the water cutting member 1a on the horizontal plane can be realized. Along with the upward movement of the lifting piece 2a, the force-bearing driving part 1-2a of the water cutting piece 1a rotates from the limit groove 3-2a to the rotation guide surface 3-11a of the limit part 3-1a, and as the top end of the limit part 3-1a of the limit piece 3a is provided with the inclined rotation guide surface 3-11a, the inclination directions of the adjacent rotation guide surface 3-11a and the lifting surface 1-21a are the same, and then under the action of the compression spring 4a, the force-bearing driving part 1-2a moves downwards into the next limit groove 3-2a along the rotation guide surface 3-11a, so that the water sealing part 1-1a is switched between the raw water inlet 8-1a and the purified water inlet 8-2 a.
Therefore, in the water cutting process, if the driving amplitude of the operating handle 1b is too small, the force-bearing driving part 1-2a only moves upwards in the limit groove 3-2a, and does not rotate on the horizontal plane beyond the limit part 3-1a, so that the water sealing part 1-1a cannot be driven to rotate, when the operating handle 1b is not driven, the force-bearing driving part 1-2a moves downwards along the limit groove 3-2a under the action of the compression spring 4a, and the water sealing part 1-1a is reset, so that the water sealing position is unchanged, namely the water discharging mode is unchanged.
When the operation handle 1b is driven, the operation handle 1b is loosened, and the operation handle 1b is reset under the action of the elastic reset piece 3b, and the principle is as follows: since both ends of the elastic restoring member 3b are respectively fixed on the operation handle 1b and the fixing member 2b, the elastic restoring member 3b is gradually deformed and stores potential energy in the process of cutting water by the operation handle 1 b; when the operating handle 1b is released, the elastic restoring member 3b releases potential energy and starts restoring, thereby driving the operating handle 1b to rotate in the opposite direction to the water cutting operation and further driving the operating handle 1b to restore. Thus, when water is switched each time, the operation handle 1b is only required to be rotated in the same direction at the same position, and the operation is simple and quick.
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.
