The faucet body 1 is provided with an inlet 11 and an outlet 12, the valve core rod 2 is connected with the faucet body 1 in a sliding manner, one end of the valve core rod is positioned inside the faucet body 1 and extends to a position between the inlet 11 and the outlet 12, the valve core which is expanded along the radial direction is arranged to control the connection and disconnection between the inlet 11 and the outlet 12, and the other end of the valve core rod is positioned outside the faucet body 1 and is connected with the driving mechanism 4 to drive the valve core rod 2 to move relative to the faucet body 1. The valve core elastic element 3 is a coil spring and is located between the water faucet body 1 and the valve core rod 2 to drive the valve core rod 2 to move relative to the water faucet body 1 to a position for cutting off the inlet 11 and the outlet 12.
The valve core rod 2 is provided with external teeth 21 and a positioning groove 22, wherein the external teeth 21 are arranged along the length direction of the valve core rod 2 and have limited length, and the positioning groove 22 is arranged on the outer surface along the radial direction of the positioning groove. The time delay assembly includes a first gear 51, a second gear 52, a third gear 53, a fourth gear 54, a friction lever 55, a winding elastic member 56, and a positioning member 57.
The first gear 51 is rotatably connected to the tap body 1 and can be in toothed engagement with the external toothing 21. The second gear 52 is coaxially rotatably connected to the first gear 51, and a ratchet 58 and a pawl 59 are provided between the first gear 51 and the second gear 52 to form unidirectional synchronous rotation between the first gear 51 and the second gear 52. Third gear 53 is rotatably connected to faucet body 1 and is in toothed engagement with second gear 52. The fourth gear 54 is in rotational connection with the tap body 1 and in toothed engagement with the third gear 53. The positioning member 57 is slidably connected to the faucet body 1 and can move relative to the faucet body 1 to extend into the positioning groove 22, so as to limit the valve core rod 2 to a position where the inlet 11 and the outlet 12 are kept communicated. One end of the friction lever 55 is rotatably connected to the faucet body 1, and the other end is in contact with the third gear 53 to form frictional resistance to the rotation of the third gear 53. The fourth gear 54 is connected to the positioning member 57, and can drive the positioning member 57 to move relative to the faucet body 1, and the rolling elastic member 56 is located between the faucet body 1 and the fourth gear 54, and can drive the fourth gear 54 to drive the positioning member 57 to move away from the connection with the positioning slot 22.
At this time, in the process of controlling the valve core rod to move upward relative to the faucet body along the direction shown in fig. 1 to enable the inlet to be communicated with the outlet, the first gear is driven by the external teeth to rotate, the first gear drives the second gear to synchronously rotate through the ratchet and the ratchet, the second gear drives the third gear to synchronously rotate, the third gear drives the fourth gear to synchronously rotate, and then the fourth gear controls the positioning piece to move relative to the faucet body.
In the process, on one hand, the rolling elastic part is in a compressed state due to the compression effect of the rolling elastic part formed by the rotation of the fourth gear, and on the other hand, the valve core rod is in a compressed state due to the compression effect of the valve core elastic part formed by the movement of the valve core rod relative to the water faucet body.
And then, when the driving acting force on the valve core rod is relieved, the winding elastic piece begins to recover the deformation and release the compression acting force, so that the fourth gear rotates reversely, the positioning piece is controlled to move reversely relative to the water faucet body and is separated from the connection with the positioning groove.
After the positioning element is completely moved out of the positioning groove, the valve core elastic element begins to recover deformation to release the compression acting force, so that the valve core rod moves downwards along the direction shown in figure 1, and the inlet and the outlet are cut off. In the process, the external teeth are meshed with the first gear again, and the first gear and the second gear enable the first gear to rotate along with the movement of the valve core rod under the connection of the ratchet wheel and the pawl, so that the channel between the inlet and the outlet is cut off smoothly.

At the moment, in the process of rolling the pull rope by utilizing the rolling wheel to rotate along with the fourth gear, the pull action force formed by the pull rope on the positioning piece is utilized to overcome the positioning elastic piece and move to be separated from the positioning groove to be connected with the positioning groove; conversely, when the winding wheel rotates reversely along with the fourth gear to release the pull rope, the positioning piece moves to be connected with the positioning groove under the driving action of the positioning elastic piece.
Further, a winding disc 513 is further arranged in the delay assembly of the embodiment, and a tension spring is adopted as the winding elastic member 56. Wherein, the winding disc 513 is coaxially and fixedly connected with the fourth gear 54, one end of the winding elastic part 56 is connected with the tap body 1, and the other end is connected with the winding disc 513.

When the valve core rod 2 moves to cut off the inlet 11 and the outlet 12, the third channel 23 moves along with the valve core rod 2 to be communicated with the second channel 14, and the first channel 13 is communicated with the inlet 11, so that a pressure action difference is formed at two ends of the cleaning head 62, and the cleaning head 62 moves relative to the water faucet body 1 to extend into the filter holes of the filter screen 61. Conversely, when the valve core rod 2 starts to move to connect the inlet 11 and the outlet 12, the third channel 23 is communicated with the first channel 13 and the second channel 14 is communicated with the inlet 11 by the movement of the valve core rod 2, and a reverse pressure action difference is formed at two ends of the cleaning head 62, so that the cleaning head 62 moves relative to the faucet body 1 to be separated from the contact with the filter screen 61, and the filter screen 61 can rotate into the channel between the inlet 11 and the outlet 12 along with the movement of the valve core rod 2.
In this embodiment, through being the faller structural style with the cleaning head design, and set up the both sides of passageway between import and export respectively with the filter screen of L shape, utilize first passageway and second passageway and import and export's intercommunication to switch, thereby form the reciprocating motion of drive cleaning head for the tap body, and then form the mediation operation control to the filter screen, simultaneously like this can also push the impurity that is located the filter end in the storage intracavity in the passageway outside between import and the export, and this storage chamber is when this tap is opened completely, when being the figure 3 position, just in time form the shutoff by the location end of filter screen, thereby avoid impurity to flow to the export along with the water, form the temporary storage effect to impurity, guarantee the water quality of export.
Similarly, in other embodiments, a cleaning head in a brush head structure driven by a motor can be adopted to brush the filtering end in the filtering net, so as to achieve the dredging effect on the filtering holes. In addition, in other implementations, the valve core rod can be designed into a slide valve structure, and different sliding grooves are directly formed in the surface of the valve core rod to form switching control over the communication relation between the first channel and the second channel and between the inlet and the outlet, so that accurate driving control over the cleaning head is achieved.
In addition, as shown in fig. 1, in the anti-clogging time-delay faucet of the present embodiment, the driving mechanism 4 is in a handle structure form, and a handle link 7 is further provided between the driving mechanism 4 and the valve core rod 2. The driving mechanism 4 is rotatably connected with the faucet body 1, one end of the handle connecting rod 7 is rotatably connected with the driving mechanism 4, and the other end of the handle connecting rod is rotatably connected with one end of the valve core rod 2, which is positioned outside the faucet body 1.
Therefore, the valve core rod can be driven through the handle connecting rod by manually lifting the driving mechanism, and the opening operation of the faucet is further formed. Likewise, in other embodiments, the driving mechanism may take other forms to provide a driving effect on the upward movement of the valve core rod.
With reference to fig. 1 to 7, the specific process of operating the anti-clogging time-delay water faucet of the present embodiment is as follows:
when the faucet is in a closed state, the valve core rod 2 moves relative to the faucet body 1 and is kept in a position of cutting off the passage between the inlet 11 and the outlet 12, the filter screen 61 is rotated to the position shown in fig. 1 by the filter link rod 63 and the filter piston 64, and the filter elastic member 65 is kept in a compressed state. At the same time, the cleaning head 62 is moved relative to the faucet body 1 into the filter holes into which the filter mesh 61 is inserted.
When the faucet needs to be opened, the manual control driving mechanism 4 lifts the valve core rod 2, and the process of completely opening the faucet is divided into the following two stages.
In the first stage, when the valve core rod 2 slightly moves to make the first channel 13 and the third channel 23 communicated, the second channel 14 is communicated with the inlet 11, the pressure difference is formed on the two sides of the cleaning head 62, and the cleaning head starts to move to be disconnected from the filter screen 61 under the pressure difference. At this stage, under the action of the elastic filtering member 65, the elastic filtering member 65 starts to recover the deformation and release the pressure when the valve core rod 2 moves, so that the filtering piston 64 and the valve core rod 2 form relative sliding and are kept unchanged in the position in the faucet body 1, and the filtering rod 63 keeps the position of the filtering net 61 unchanged, that is, the position shown in fig. 2, thereby ensuring that the cleaning head 62 can smoothly and quickly move to be disconnected from the filtering net 61.
In the second stage, after the cleaning head 62 is disconnected from the filter screen 61, the manual control driving mechanism 4 continues to lift the valve core rod 2, at this time, the valve core rod 2 drives the first gear 51 to rotate through the external teeth 21, so as to drive the fourth gear 54 to rotate through the second gear 52 and the third gear 53 in sequence, and then the fourth gear 54 drives the winding wheel 511 to release the pull rope 512, so that the positioning element 57 moves toward the direction of the valve core rod 2 under the action of the positioning elastic element 510. When the positioning groove 22 moves along with the valve core rod 2 to be aligned with the positioning piece 57, the positioning piece 57 extends into the positioning groove 22 under the driving action of the positioning elastic piece 510, so as to form a movement limitation on the valve core rod 2 relative to the faucet body 1, so that the valve core rod 2 is kept at a position where the inlet 11 is communicated with the outlet 12, and the water at the inlet 11 flows to the outlet 12 and flows out from the outlet 12, thereby completing the opening operation of the faucet. At this stage, when the valve core rod 2 moves relative to the water faucet body 1 until the filtering elastic member 65 is completely deformed and presses the filtering piston 64 and the valve core rod 2 together, the subsequent movement of the valve core rod 2 starts to drive the filtering net 61 to rotate through the filtering piston 64 and the filtering connecting rod 63, so that the filtering end of the filtering net rotates into the channel between the inlet 11 and the outlet 12, and finally rotates to the position shown in fig. 3.
Meanwhile, when the faucet is in the full start state, the external teeth 21 are disengaged from the teeth of the first gear 51, the valve core elastic member 3 is in a compressed state by the movement of the valve core rod 2 relative to the faucet body 1, and the winding elastic member 56 is in a stretched state with the rotation of the winding disc 513.
When the faucet needs to be closed in a delayed mode, the acting force on the driving mechanism 4 is released, and the faucet automatically carries out a delayed phase and a closing phase.
In the delay stage, after the acting force on the driving mechanism 4 is released, since the first gear 51 is disengaged from the external teeth 21, the winding disc 513 can drive the third gear 53, the second gear 52 and the first gear 51 to synchronously rotate in the reverse direction through the fourth gear 54 under the restoring acting force of the winding elastic member 56, and further drive the winding wheel 511 to rotate in the reverse direction to wind the pull rope 512, so as to drive the positioning member 57 to move away from the connection with the positioning groove 22 against the acting force of the positioning elastic member 510. At this stage, due to the frictional contact between the friction rod 55 and the friction wheel 514, the rotation speed of the third gear 53 is greatly reduced, so that the winding speed of the winding wheel 511 on the pull rope 512 is reduced, the positioning element 57 is gradually and slowly moved out of the positioning groove 22, the purpose of slowly releasing the limiting of the valve core rod 2 is achieved, and the time delay effect is achieved.
In the closing stage, after the positioning element 57 is pulled by the pulling rope 512 to overcome the positioning elastic element 510 and move completely out of the positioning groove 22, the time delay stage is over, and the valve core rod 2 starts to move reversely relative to the faucet body 1 under the restoring force of the valve core elastic element 3. At this stage, on the one hand, the external teeth 21 are in toothed engagement with the first gear 51 again, but since the first gear 51 alone rotates with the movement of the spool rod 2, the second gear 52, the third gear 53 and the fourth gear 54 remain stationary, due to the unidirectional transmission connection between the first gear 51 and the second gear 52, between the ratchet 58 and the pawl 59; on the other hand, because the end of the third channel 13 extends along the length direction of the valve core rod 2, during the movement of the valve core rod 2, the first channel 13 is always communicated with the third channel 23, and the second channel 14 is always communicated with the inlet 11, so that the cleaning head 62 is always kept away from the filter screen 61; on the other hand, in the process that the valve core elastic element 3 pushes the valve core rod 2 to move, the filtering piston 64 pushes the filtering screen 61 to rotate through the filtering connecting rod 63 under the action of the filtering elastic element 65, so that the filtering end of the filtering screen 61 is rotated out of the channel between the inlet 11 and the outlet 12, namely, the position shown in fig. 2, at this time, the valve core rod 2 is not completely moved in place, under the further driving action of the valve core elastic element 3, the valve core rod 2 continues to move, under the contact positioning between the positioning end in the filtering screen 61 and the water faucet body 1, the relative movement is formed between the valve core rod 2 and the filtering piston 64 to compress the filtering elastic element 65, and then the filtering screen 61 is subjected to pretightening force through the filtering piston 64 and the filtering connecting rod 63, so that the filtering screen 61 is stabilized at the position shown in fig. 1. To this end, the valve core rod 2 is moved to the position shown in fig. 1, and the passage between the inlet 11 and the outlet 12 is cut off, thereby completing the closing operation of the water faucet.
When the valve core rod 2 moves to the closing position of the faucet, the first channel 13 is communicated with the inlet 11 again, and the second channel 14 is communicated with the outlet 12 through the third channel 23, so that a reverse pressure action difference is formed at two ends of the cleaning head 62, the cleaning head 62 starts to move towards the direction close to the filter screen 61 until the needle end on the cleaning head 62 extends into the filter hole of the filter screen 61, namely the state shown in fig. 1, and then the dredging operation of the filter screen 61 is achieved.
