[0037] Alternatively, the water outlet of the first water outlet is suitable for dispersing in all directions, so the nozzle does not need to rotate to allow the water flowing out of the first water outlet to clean the side walls of the basin. This structure improves the pull-out faucet to clean the side walls of the basin, which is simpler and more versatile than improving the structure of the basin.

[0038] 2. In the second scheme and its preferred embodiment, in the above method, the user can apply force to the pull-out head so that the pull-out head is in the second position, and needs to hold the pull-out head to ensure the stability of the position.

The two ends of the first reset member act on the first locking member and the clamping sleeve respectively, so that when the sliding member and the first locking member are separated from the inclined surface, the first locking member moves in a direction away from the drawing tube, so that when the sliding member is not subjected to the force of the sliding member, the first locking member releases the drawing tube to ensure the normal use of the drawing tube.

[0041] 4. In the fourth scheme and its preferred embodiment, the transmission mechanism further includes a second locking member and a second resetting member.

[0043] 5. Scheme 5 and its preferred embodiment also include a limit member, which is provided with a limit surface suitable for abutting against the sliding member to limit its sliding position, thereby controlling the stroke of the sliding member to achieve the purpose of controlling the pulling stroke of the pull-out tube during automatic cleaning. The pulling head can be extended into a fixed position in the basin each time to ensure the cleaning effect.

[0044] 6. In the sixth scheme and its preferred embodiment, when the first water outlet cannot be used for daily use, such as the water outlet direction is unreasonable, at least one water outlet is still needed for daily use. In this scheme, the pull-out head is also provided with a second water outlet, which is arranged on the side of the pull-out head, and the nozzle is arranged at the end of the pull-out head; when the pull-out head is in the first position, the second water outlet is suitable for facing the bottom of the basin for daily use, and the water outlet direction of the second water outlet is inclined forward, so that the water outlet area of ​​the second water outlet can be reached without stretching the arm, which is more convenient to use.

[0045] 7. In scheme seven and its preferred embodiments, when the pull-out head is in the first position, the first water outlet is not facing the side wall of the basin; the pull-out head is suitable for flipping so that when the nozzle is in the second position, the water outlet direction of the first water outlet is directed to the side wall of the basin, thereby ensuring the cleaning of the basin. In some embodiments, this arrangement is intended to enable the second water outlet to face the bottom of the basin and the water outlet direction to be inclined forward when the pull-out head is in the first position.

[0048] The first elastic member is adapted to be gradually stretched when the pull-out head moves to the second position, and the second elastic member is adapted to be gradually reset from the stretched state when the pull-out head moves to the second position, so that when the pull-out head is in the second position, the water outlet direction of the first water outlet points to the side wall of the basin. The counterweight block can also stabilize the pull-out head to prevent the pull-out member from swinging due to the reaction force of water when water is discharged from the first water outlet and / or the second water outlet, resulting in a change in the water outlet direction and affecting the use.

[0049] 9. In the ninth solution and its preferred embodiment, the counterweight block is configured to be disconnected from the pulling head when the force applied to the counterweight block and away from the outer tube is greater than a first threshold, so that the pulling stroke of the pulling head is not limited by the position of the counterweight block.

[0074] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0075] refer to Figure 1-Figure 7 A pull-out faucet is suitable for cleaning the side wall of a basin, which can be a sink, a wash basin, etc. The pull-out faucet includes an outer tube 1, a pull-out member 2, a driving mechanism 3, a transmission mechanism 4, a controller, a first elastic member 5, a second elastic member 6, a counterweight block 7, a gravity hammer 8 and a limit member 9;

[0076] refer to Figure 1 The middle of the outer tube 1 is through, and a handle can be installed on the outer tube 1 to control the water path of the drawer 2. The outer tube 1 includes a vertical section 11 and a connecting section 12 extending forward from the vertical section 11. In this embodiment, the connecting section 12 is an inclined section extending forward and inclined upward. In other embodiments, the connecting section 12 can also be a horizontal section. In this embodiment, the vertical section 11 is located at the rear side of the basin and is fixed to the countertop. The inclined section extends forward to the top of the basin.

[0077] refer to Figure 1 , Figure 3The pull-out member 2 includes a pull-out tube 21 and a pull-out head 22 connected to each other. One end of the pull-out tube 21 is connected to the pull-out head 22, and the other end passes through the outer tube 1 and cooperates with the transmission mechanism 4 under the table, the gravity hammer 8, the water pipe in the wall, etc.

[0078] The pull-out head 22 includes a nozzle 221, and the pull-out head 22 is also provided with a second water outlet 222, and the second water outlet 222 is arranged at the side of the pull-out head 22, and the nozzle 221 is arranged at the end of the pull-out head 22, and the nozzle 221 is provided with a first water outlet 2211; the pull-out head 22 is suitable for moving relative to the outer tube 1, so that the pull-out head 22 is located at a first position outside the basin and a second position inside the basin, wherein the first position is usually a position for daily use, and the relative position is relatively fixed, and is generally a position where the pull-out head 22 and the outer tube 1 are limited. The second water outlet 222 is positioned at the bottom of the basin, and the water outlet direction of the second water outlet 222 is tilted forward. The setting of the tilted section allows the water outlet direction of the second water outlet 222 to be in the above direction after the pull-out head 22 is installed, which is more convenient. The second position is the cleaning position of the side wall of the basin, which can refer to a fixed position relative to the basin, or a certain interval relative to the movement of the basin. When the pull-out head 22 is in the second position, the water outlet direction of the first water outlet 2211 points to the side wall of the basin. The water path switching between the first water outlet 2211 and the second water outlet 222 can be controlled by a solenoid valve or a mechanical valve.

[0079] When the pull-out head 22 is in the second position, the nozzle 221 is suitable for rotating around the first axis 10 so that the water outlet direction of the first water outlet 2211 points to the side walls of the basin to achieve the purpose of cleaning the side walls, wherein the first axis 10 is parallel to the up and down direction. That is, the nozzle 221 is suitable for rotating relative to other parts of the pull-out head 22. At this time, one or more first water outlets 2211 can be provided. Preferably, the first water outlets 2211 are an even number, and the water outlet direction of one first water outlet 2211 is opposite to the water outlet direction of another first water outlet 2211 to offset the reaction force of water on the nozzle 221 when the water is discharged, causing the pull-out head 22 to deflect and splash water. The rotation of the nozzle 221 can be driven by hydraulic power or by a motor. This is a conventional technical means in this field and will not be described in detail here. Preferably, hydraulic drive is adopted to save more energy. Or the water outlet direction of the first water outlet 2211 is suitable for diverging to the surroundings. For example, it is common to set a ejector pin at the water outlet direction of the first water outlet 2211. When the water flow hits the ejector pin, it will diverge to the surroundings to achieve the purpose of cleaning each side wall.

[0080] refer to Figure 3-Figure 5The driving mechanism 3 can be a motor. The driving mechanism 3 is suitable for driving the transmission mechanism 4, so that the transmission mechanism 4 clamps the drawing tube 21 and drives the drawing tube 21 to move through the transmission mechanism 4, so that the drawing head 22 can at least be located in the second position under the action of the motor. The transmission mechanism 4 is also suitable for loosening the drawing tube 21 to ensure normal use.

[0081] Specifically, the transmission mechanism 4 includes a clamping sleeve 41, a sliding member 42, a first locking member 43, a first restoring member 44, a second locking member 45 and a second restoring member 46;

[0082] The sliding member 42 is suitable for being driven by the driving mechanism 3 to slide up and down. For example, common gear rack mechanism, screw nut mechanism and other mechanisms can realize the sliding of the sliding member 42.

[0083] The clamping sleeve 41 is sleeved on the drawing tube 21 . The first locking member 43 is suitable for sliding in the horizontal direction relative to the clamping sleeve 41 . The first locking member 43 is installed in the groove of the clamping sleeve 41 .

[0084] like Figure 5 As shown, the sliding member 42 is suitable for cooperating with the inclined surface of the first locking member 43 when sliding upward, so that the first locking member 43 moves toward the pull-out tube 21, and the clamping sleeve 41 and the first locking member 43 clamp the pull-out tube 21 together, that is, at least one of the sliding member 42 and the first locking member 43 is provided with an inclined surface (in this embodiment, the first locking member 43 has an inclined surface), so that the vertical movement of the sliding member 42 is converted into the horizontal movement of the first locking member 43. When the first locking member 43 moves toward the pull-out tube 21, the pull-out tube 21 is pushed against the clamping sleeve 41 to achieve the clamping effect. At this time, when the sliding member 42 continues to move upward, it also pushes the first locking member 43, so that the transmission mechanism 4 and the pull-out tube 21 move upward together.

[0085] refer to Figure 4 The two ends of the first restoring member 44 act on the first locking member 43 and the clamping sleeve 41 respectively, so that when the sliding member 42 and the first locking member 43 are out of the inclined surface cooperation, the first locking member 43 moves away from the pulling tube 21, thereby achieving unlocking, ensuring that the pulling of the pulling member 2 during normal use will not be locked due to the action of the transmission mechanism 4.

[0086] refer to Figure 4 Similarly, the sliding member 42 is suitable for cooperating with the inclined surface of the second locking member 45 when sliding downward, so that the second locking member 45 moves toward the pull-out tube 21, and the clamping sleeve 41 and the second locking member 45 jointly clamp the pull-out tube 21, and the sliding member 42 is also suitable for driving the second locking member 45 to slide downward, so that the transmission mechanism 4 and the pull-out tube 21 move downward together, thereby realizing the resetting of the transmission mechanism 4 and the pull-out tube 21.

[0087] The two ends of the second reset member 46 act on the second locking member 45 and the clamping sleeve 41 respectively, so that when the sliding member 42 and the second locking member 45 are separated from the inclined surface, the second locking member 45 moves away from the drawing tube 21, thereby achieving unlocking, ensuring that the drawing member 2 is pulled out during normal use without being locked by the transmission mechanism 4. The first reset member 44 and the second reset member 46 can both be springs.

[0088] In the above-mentioned embodiment of the transmission mechanism 4, the locking and driving the pull-out tube 21 to move are achieved through the movement of the sliding member 42. In other embodiments, the locking and driving the pull-out tube 21 to move can be driven by two components respectively. For example, the transmission mechanism 4 includes a locking member and a sliding member 42. When the locking member is driven, the pull-out tube 21 is locked. After the locking is completed, the sliding member 42 is driven to move, so that the sliding member 42 pushes the locking member to achieve the movement of the pull-out tube 21. At the same time, the locking member is also suitable for unlocking the pull-out tube 21.

[0089] refer to Figure 6 , Figure 7 The limiting member 9 is provided with a limiting surface 931 suitable for abutting against the sliding member 42 to limit its sliding position. Specifically, the limiting member 9 is provided with a slide groove 91 and a limiting column 93. The slide groove 91 is for the sliding member 42 to slide. The slide groove 91 is provided with a plurality of limiting holes 92 arranged along the vertical direction. The limiting column 93 is inserted into the limiting hole 92 to form the limiting surface 931. The installation position of the limiting column 93 can be selected according to the actual installation situation, thereby selecting the position of the limiting surface 931.

[0090] refer to Figure 1 The gravity hammer 8 is suitable for resetting the pull head 22 to the first position when the pull member 2 is not subjected to force. When the corresponding locking member and the clamping sleeve 41 clamp the pull tube 21, the gravity hammer 8 does not play a role. In some embodiments, in order to realize the pull head 22 to be reset to the first position, the gravity hammer 8 may not be used.

[0091] After the sliding member 42 slides downward to unlock the pulling tube 21 with the first locking member 43, it continues to slide downward to lock the pulling tube 21 with the second locking member 45, and continues to slide the sliding member 42 downward to reset the pulling head 22. Since the conversion process is relatively fast, the gravity hammer 8 will not reset the pulling head 22 when the first locking member 43 unlocks the pulling tube 21.

[0092] In this embodiment, when the nozzle 221 is in the first position, the first water outlet 2211 is not facing the side wall of the basin, and the first water outlet 2211 is also facing the bottom of the basin. Therefore, when the pull-out head 22 moves to the second position, it is necessary to flip it so that when the nozzle 221 is in the second position, the water outlet direction of the first water outlet 2211 points to the side wall of the basin.

[0093] refer to Figure 1-Figure 3In order to make the automatic flipping of the pull head 22 more stable when the driving mechanism 3 is working, that is, when the pull head 22 is in the second position, the water outlet direction of the first water outlet 2211 is guaranteed to point to the side wall of the basin. In this embodiment, the first elastic member 5, the second elastic member 6 and the counterweight block 7 are used to achieve this.

[0094] Specifically, the two ends of the first elastic member 5 are respectively connected to the outer tube 1 and the counterweight 7, the two ends of the second elastic member 6 are respectively connected to the outer tube 1 and the counterweight 7, and the first elastic member 5 is located on the upper side of the second elastic member 6. The first elastic member 5 is suitable for being gradually stretched when the pull-out head 22 moves to the second position, and the second elastic member 6 is suitable for gradually resetting from the stretched state when the pull-out head 22 moves to the second position. Specifically, when the pull-out head 22 is in the first position, the first elastic member 5 is in a non-energy storage state or a compressed state, and the second elastic member 6 is in a stretched state. When the pull-out head 22 is in the second position, the first elastic member 5 is stretched, and the second elastic member 6 is reset from the stretched state under the action of the pull-out head 22 and the counterweight 7. The number of the first elastic member 5 and the second elastic member 6 can be only one, or multiple.

[0095] The counterweight 7 is sleeved on the pull-out tube 21 and connected to the pull-out head 22, and the counterweight 7 is also connected to the outer tube 1 through the first elastic member 5 and the second elastic member 6, so that the distance of the counterweight 7 relative to the outer tube 1 is limited. The configuration block is also directly connected to the outer tube 1, and the counterweight 7 is configured to be disconnected from the outer tube 1 when the force applied to the counterweight 7 and away from the outer tube 1 is greater than the second threshold, for example, the counterweight 7 is clamped or magnetically connected or plugged with the outer tube 1, wherein the magnetic connection is the simplest and easiest to implement. The counterweight 7 is configured to be disconnected from the pull-out head 22 when the force applied to the counterweight 7 and away from the outer tube 1 is greater than the first threshold, so that the pull-out head 22 can be separated from the counterweight 7, thereby having a larger pull-out length, for example, the counterweight 7 is clamped or magnetically connected or plugged with the pull-out head 22, wherein the magnetic connection is the simplest and easiest to implement, and preferably, the two ends of the counterweight 7 are respectively suitable for magnetic connection with the pull-out head 22 and the outer tube 1. The second threshold is smaller than the first threshold, so that when the pulling head 22 moves away from the outer tube 1 , the counterweight 7 and the pulling head 22 first move relative to the outer tube 1 , and then the pulling head 22 moves relative to the counterweight 7 .

[0096] Of course, in other embodiments, the pull-out head 22 may also be vertically lowered. When the pull-out head 22 is at the first position, the water outlet direction of the first water outlet 2211 is suitable for pointing to the direction of the side wall of the basin.

[0097] This embodiment also provides a basin cleaning method, specifically, refer to Figure 1-Figure 3The controller of the pull-out faucet is adapted to control the driving mechanism 3 to work when receiving a cleaning instruction, so that the driving mechanism 3 drives the transmission mechanism 4, so that the transmission mechanism 4 clamps the pull-out member 2, and drives the pull-out tube 21 to move through the transmission mechanism 4, so that the nozzle 221 moves to the second position. Specifically, the driving mechanism 3 controls the sliding member 42 to slide upward, and the sliding member 42 cooperates with the inclined surface of the first locking member 43, so that the first locking member 43 moves toward the pull-out tube 21, and the clamping sleeve 41 and the first locking member 43 clamp the pull-out tube 21 together, and then when the sliding member 42 continues to move upward, it moves upward by pushing the first locking member 43. Since the pull-out tube 21 is clamped at this time, the transmission mechanism 4 and the pull-out tube 21 move upward together. During this process, first, the counterweight 7 is separated from the magnetic cooperation with the outer tube 1, and the counterweight 7 moves together with the pull-out head 22. The first elastic member 5 and the second elastic member 6 are pulled by the counterweight 7, the first elastic member 5 is stretched, the second elastic member 6 is contracted, and the pull-out head 22 begins to flip. When the first elastic member 5 is stretched to its longest, the pull-out head 22 is separated from the magnetic cooperation with the counterweight 7, and the pull-out head 22 further moves downward relative to the counterweight 7.

[0098] When the nozzle 221 is in the second position, and the water outlet direction of the first water outlet 2211 is suitable for dispersing in all directions, or the nozzle 221 is rotated by hydraulic drive, the water path of the nozzle 221 is directly opened (the solenoid valve is controlled by the controller to open the water path of the nozzle 221, or the water path of the nozzle 221 is opened manually) to clean the basin.

[0099] Preferably, when the nozzle 221 is at the second position and the nozzle 221 needs to be electrically driven to rotate, while the water path of the nozzle 221 is opened, the nozzle 221 is also driven to rotate to clean the basin.

[0100] During the cleaning process, the nozzle 221 can always be located at one position in the vertical direction, or it can slide up and down repeatedly through the action of the sliding member 42 to improve the cleaning effect.

[0101] When cleaning is completed, the driving mechanism 3 drives the sliding member 42 to move in the opposite direction, and the clamping sleeve 41 and the second locking member 45 clamp the drawing tube 21 together. Then, when the sliding member 42 continues to move downward, by pushing the second locking member 45 to move downward, since the drawing tube 21 is clamped at this time, the transmission mechanism 4 and the drawing tube 21 move downward together. First, the drawing head 22 and the counterweight block 7 are magnetically matched again, and then the counterweight block 7 is driven to reset until the counterweight block 7 and the outer tube 1 are magnetically matched again, and the drawing head 22 reaches the first position. Finally, the sliding member 42 is driven to slide slightly upward to achieve unlocking.

[0102] Compared with the prior art, this embodiment has the following beneficial effects:

[0104] The outer tube 1 is usually used to support the drawer 2 and install a waterway control handle and the like.

[0105] The pull-out member 2 includes a pull-out tube 21 and a pull-out head 22 connected to each other. The pull-out head 22 includes a nozzle 221. The nozzle 221 is provided with a first water outlet 2211. The pull-out head 22 is suitable for moving relative to the outer tube 1 so that the pull-out head 22 is located at a first position outside the basin. At this time, the pull-out head 22 is limited to the outer tube 1 to ensure that the basin is not interfered with by the pull-out head 22 during daily use and affects the use experience. The pull-out head 22 can also be located at a second position inside the basin. The pull-out head 22 is located at a second position. position, the water outlet direction of the first water outlet 2211 points to the side wall of the basin to clean the side wall of the basin, and the nozzle 221 is suitable for rotating around the first axis 10 so that the water outlet direction of the first water outlet 2211 points to the side walls of the basin, thereby allowing the first water outlet 2211 to clean the side walls of the basin, wherein the nozzle 221 is suitable for being driven by water power or a motor to rotate around the first axis 10, thereby changing the water outlet direction of the first water outlet 2211.

[0106] Alternatively, the water outlet direction of the first water outlet 2211 is suitable for diverging in all directions, so the nozzle 221 can make the water flowing out of the first water outlet 2211 clean the side walls of the basin without rotating. This structure improves the pull-out faucet to clean the side walls of the basin, which is simpler and more versatile than improving the structure of the basin.

[0107] In an exemplary embodiment, in the above method, the user can apply force to the pull-out head 22 so that the pull-out head 22 is located in the second position, and needs to hold the pull-out head 22 to ensure that the position is stable. In this solution, in order to reduce the complexity of the operation, the solution also includes a driving mechanism 3 and a transmission mechanism 4, and the driving mechanism 3 is suitable for driving the transmission mechanism 4 to provide power to the transmission mechanism 4. When the transmission mechanism 4 is driven, it is suitable for clamping the pull-out tube 21, so that the movement of the pull-out tube 21 is driven by the movement of the transmission mechanism 4, thereby realizing the movement of the pull-out head 22, thereby eliminating the need for manual operation by the user. And the transmission mechanism 4 is also suitable for loosening the pull-out tube 21, so that the transmission mechanism 4 no longer restricts the pull-out tube 21, so as to ensure the user's daily pulling of the pull-out member 2.

The two ends of the first reset member 44 act on the first locking member 43 and the clamping sleeve 41 respectively, so that when the sliding member 42 and the first locking member 43 are separated from the inclined surface, the first locking member 43 moves in a direction away from the drawing tube 21, so that when the sliding member 42 is not subjected to the force of the sliding member 42, the first locking member 43 releases the drawing tube 21, ensuring the normal use of the drawing tube 21.

[0110] In an exemplary embodiment, the transmission mechanism 4 further includes a second locking member 45 and a second resetting member 46. The sliding member 42 is adapted to cooperate with the inclined surface of the second locking member 45 when sliding downward, so that the second locking member 45 moves toward the drawer tube 21, and the clamping sleeve 41 and the second locking member 45 clamp the drawer tube 21 together, thereby achieving the function of clamping the drawer tube 21, and the sliding member 42 is also adapted to drive the second locking member 45 to slide downward; thus, the drawer tube 21 can be pushed downward to move downward, and the drawer head 22 can be reset to the first position, or repeatedly moved up and down in the basin to improve the cleaning effect.

[0111] The two ends of the second reset member 46 act on the second locking member 45 and the clamping sleeve 41 respectively, so that when the sliding member 42 and the second locking member 45 are disengaged from the inclined surface, the second locking member 45 moves away from the pull-out tube 21, so that when the sliding member 42 is not acted upon, the second locking member 45 releases the pull-out tube 21, thereby ensuring the normal use of the pull-out tube 21.

[0112] In an exemplary embodiment, a limit member 9 is further included, which is provided with a limit surface 931 suitable for abutting against the sliding member 42 to limit its sliding position, thereby controlling the stroke of the sliding member 42 to achieve the purpose of controlling the pulling stroke of the pulling tube 21 during automatic cleaning. The pulling head 22 can be extended into a fixed position in the basin each time to ensure the cleaning effect.

[0113] In an exemplary embodiment, when the first water outlet 2211 cannot be used for daily use, such as the direction of water outlet is unreasonable, at least one water outlet is still needed for daily use. In this solution, the pull-out head 22 is also provided with a second water outlet 222, and the second water outlet 222 is provided on the side of the pull-out head 22, and the nozzle 221 is provided at the end of the pull-out head 22; when the pull-out head 22 is in the first position, the second water outlet 222 is suitable for facing the bottom of the basin for daily use, and the water outlet direction of the second water outlet 222 is inclined forward, and the water outlet area of ​​the second water outlet 222 can be reached without stretching the arm, which is more convenient to use.

In some embodiments, this arrangement is to enable the second water outlet 222 to face the bottom of the basin and tilt the water outlet direction forward when the pull-out head 22 is in the first position.

[0115] In an exemplary embodiment, in order to ensure the stability of the pull head 22 when flipping under the action of the driving mechanism 3 and the transmission mechanism 4, the present solution further includes a first elastic member 5, a second elastic member 6 and a counterweight 7.

[0116] The counterweight block 7 is sleeved on the drawing tube 21 and connected to the drawing head 22. The first elastic member 5 and the second elastic member 6 are connected to the outer tube 1 and the counterweight block 7 at both ends. The first elastic member 5 is located on the upper side of the second elastic member 6.

[0117] The first elastic member 5 is adapted to be gradually stretched when the pull-out head 22 moves to the second position, and the second elastic member 6 is adapted to be gradually reset from the stretched state when the pull-out head 22 moves to the second position, so that when the pull-out head 22 is in the second position, the water outlet direction of the first water outlet 2211 points to the side wall of the basin. The counterweight block 7 can also stabilize the pull-out head 22, preventing the reaction force of water from causing the pull-out member 2 to swing when water is discharged from the first water outlet 2211 and / or the second water outlet 222, resulting in a change in the water outlet direction and affecting the use.

[0118] In an exemplary embodiment, the counterweight 7 is configured to be disconnected from the pulling head 22 when the force applied to the counterweight 7 and away from the outer tube 1 is greater than a first threshold, so that the pulling stroke of the pulling head 22 is not limited by the position of the counterweight 7.

When the second threshold value is less than the first threshold value, the counterweight block 7 can be separated from the outer tube 1 first, and then move with the pull-out head 22 to achieve the flipping of the pull-out head 22, and then the pull-out head 22 can be separated from the counterweight block 7.

[0121] In an exemplary embodiment, the counterweight 7 is snap-fitted, magnetically connected or plugged into the pull-out head 22 and / or the outer tube 1, thereby having a certain connection function, but being able to be detached when subjected to force, wherein the magnetic connection is easier to achieve.
