[0040] The pull-out faucet often used in daily life brings much convenience to people because of its convenient pull-out. However, the pull-out structure principles of most pull-out faucets on the market are basically similar, basically all of which adopt a weight at the bottom of the water pipe to help reset the water pipe, when the user operates, the spray head is pulled out to the separated state, the water pipe is always pulled by the weight, and the reverse pulling force needs to be applied to the water pipe after being pulled out to maintain its normal use, otherwise the water pipe will reset under the action of the weight, which is very laborious and inconvenient to clean.

[0041] Therefore, the present application provides a pull-out hovering mechanism, which aims to automatically maintain hovering after the water pipe is pulled out, thereby liberating the hands of the user.

[0042] Referring to Figure 1 The pull-out hovering mechanism 200 has compact product structure, does not occupy the space under the table, can be directly installed on the existing pull-out faucet 100 product, such as a pull-out basin faucet, a pull-out kitchen faucet, etc., the pull-out hovering mechanism 200 can be pre-assembled into an independent housing 210 assembly and a hovering assembly 400, when used, the pipe buckle 410 of the hovering assembly 400 is assembled with the water pipe 110, and then the water pipe 110 passes through the pipe cavity 224 of the housing 210, which is simple in structure and convenient and efficient in installation.

[0043] Referring to Figures 2-9In the embodiment of the present application, the pulling and hovering mechanism 200 comprises a housing 210, a hovering assembly 400, a positioning spring 700 and an elastic reset member 800. The housing 210 has a through pipe cavity 224 extending along the length direction of the housing 210, through which the water pipe 110 can pass. The pipe fastener 410 is fixedly connected with the outer peripheral wall of the water pipe 110 and can move along with the water pipe 110 in the through pipe cavity 224. The side wall of the through pipe cavity 224 is provided with a positioning step 310 along the extending direction. The pipe fastener 410 is provided with a pawl 500 and an abutting spring 600 mounted on the pipe fastener 410. The pawl 500 comprises a rotating part 520 rotatably connected with the pipe fastener 410, a lower pawl part 530 and an upper pawl part 510 respectively located at two ends of the rotating part 520. The abutting spring 600 abuts against the lower pawl part 530, so that the lower pawl part 530 has a tendency to rotate away from the pipe fastener 410.

[0044] With reference to Figures 4-9 When the water pipe 110 is pulled, the pipe fastener 410 moves in the through pipe cavity 224. When the pawl 500 moves above the positioning step 310, the pawl 500 is pushed by the abutting spring 600 to approach the positioning step 310. At this time, the water pipe 110 is hovered, i.e. the water pipe 110 moves back under the driving of the weight 120, but the pawl 500 is blocked by the step and remains at the position after being pulled. At this time, the user does not need to exert force to overcome the force of the weight 120 to avoid the water pipe 110 from being recovered, so that the use is more convenient.

[0045] Without considering the size of the pulling and hovering mechanism 200, the positioning step 310 can be provided with multiple levels, so as to realize multiple levels of hovering, i.e. after the water pipe 110 is pulled, the pawl 500 is clamped on the positioning step 310 at different positions, so as to realize the hovering of the water pipe 110 at different pulling lengths without manual operation.

[0046] The pawl 500 and the positioning step 310 are used to realize the hovering, so that the overall structure is simple, the parts are few and the assembly is convenient. Specifically, the pawl 500 is arranged on the pipe fastener 410, the pipe fastener 410 is connected with the water pipe 110, and the hovering assembly 400 is pre-assembled. Therefore, when the water pipe 110 and the pipe fastener 410 are assembled, the water pipe 110 can pass through the housing 210. Because the pawl 500 is arranged on the pipe fastener 410, the pawl 500 cooperates with the positioning step 310 at the side wall of the housing 210 in the housing 210, so that the space occupied by the faucet 130 is small, the space requirement for the modification position is low, the installation cost can be reduced, the cooperation of the pawl 500 and the positioning step 310 can accurately determine the hovering position of the faucet 130, the cooperation of the pawl 500 and the positioning step 310 has good locking effect, and the product has good use effect.

[0047] Resetting of the pull-out hovering mechanism 200.

[0048] In an embodiment, a manual button can be used to reset the hovering assembly 400, for example, a passageway is arranged in the middle of the positioning step 310, and the button is arranged in the passageway. When resetting is needed, the button is manually pressed to make the pawl 500 disengage from the positioning step 310, so as to reset the hovering assembly 400.

[0049] In another embodiment, the electromagnetic adsorption method can be used to reset the hovering assembly 400. With the development of smart home, that is, the home devices connected through the Internet of Things technology are connected into an organic system, and the user can control the system at any time and any place. The application scenarios of smart home will be more and more, therefore, the pull-out faucet 100 can also be part of the system. For example, the user controls the water outlet of the faucet 130 through voice, and manually pulls out to make the pawl 500 abut against the positioning step 310 or sets a driving mechanism in the faucet 130 to make the pawl 500 abut against the positioning step 310. When resetting is needed, the pawl 500 is adsorbed close to the pipe fastener 410 through an instruction such as voice, gesture, etc., so as to reset the hovering assembly 400.

[0050] Specifically, in the present embodiment, referring to Figures 4-7 , the abutting convex part 320 is located above the positioning step 310. When the user needs to reset the pull-out faucet 100, or in other words, needs to make the faucet return to the initial position, the water pipe 110 is continuously pulled out, so that the pawl lower part 530 is pushed close to the pipe fastener 410 by the abutting convex part 320, and the opposite pawl upper part 510 is away from the pipe fastener 410. After the pawl upper part 510 exceeds the positioning spring 700, it is limited by the abutting positioning spring 700. At this time, the pawl lower part 530 remains close to the pipe fastener 410, and the water pipe 110 is reset under the action of the weight 120. When the user releases the hand, the water pipe 110 is driven back by the weight 120, and the positioning spring 700 abuts against the pawl upper part 510 to limit the movement trend of the pawl lower part 530, so that the pawl lower part 530 does not abut against the positioning step 310 during the reset of the water pipe 110, or in other words, the pawl lower part 530 does not abut against the positioning step 310 during the movement of the water pipe 110 back, so as to reset the faucet 130. Whether it is hovering or resetting of the faucet 130 is automatically achieved by the ingenious mechanical structure, without manual operation, smooth pulling out, and good hovering position sensing.

[0051] Referring to Figures 7-9In order to enable the pawl 500 to abut against the positioning step 310 to achieve suspension in the next use, an elastic reset member 800 is arranged at the bottom of the shell 210, and a portion of the elastic reset member 800 is telescopically arranged in the through pipe cavity 224; when the pawl lower portion 530 passes through the elastic reset member 800, the extended portion of the elastic reset member 800 is in contact with the pawl lower portion 530, and the extended portion of the elastic reset member 800 moves into the shell 210, at this time, the restriction between the pawl upper portion 510 and the positioning spring 700 is broken, and the pawl lower portion 530 moves away from the pipe fastener 410 under the action of the abutment spring 600; thus, when the user next pulls the water pipe 110, the pawl 500 can repeat the previous action to abut against different positioning steps 310 to achieve suspension, and under the abutment action of the positioning spring 700, the reset action is achieved, and under the action of the elastic reset member 800, the initial state is restored.

[0053] With reference to Figure 3 As a further scheme, in order to solve the problem of machining the abutting protrusion 320 and the positioning groove, the pull-out and hovering mechanism 200 further comprises a ratchet 300, the positioning step 310 and the abutting protrusion 320 are arranged on the ratchet 300, the shell 210 further comprises a mounting cavity 221 communicating with the pipe passing cavity 224, and the ratchet 300 is mounted in the mounting cavity 221.

[0054] Specifically, the through pipe cavity 224 of the housing 210 is for the water pipe 110 to pass through. The installation cavity 221 is located on the side wall of the housing 210. The ratchet bar 300 is fixed in the installation cavity 221. On the side of the ratchet bar 300 facing the through pipe cavity 224, there is a positioning step 310.

The abutting convex portion 320 is located at the end of the uppermost positioning step 310. By arranging the positioning step 310 and the abutting convex portion 320 on the ratchet bar 300, on the one hand, it is convenient for processing and reduces the processing cost of the housing 210. On the other hand, it is also convenient for installing or replacing the ratchet bar 300.

[0055] In other embodiments, on the side wall of the through pipe cavity 224, there are an abutting convex portion 320 and a positioning step 310 arranged along the extending direction of the side wall of the through pipe cavity 224.

[0056] As a further solution, to solve the problem of the installation and fixation of the end cap 230 and the outer shell 220, a matching clamping structure 240 is provided between the end cap 230 and the outer shell 220, and the end cap 230 and the outer shell 220 are clamped and fixed.

[0057] Specifically, the end cap 230 is in a "匚" shape, and there are buckle catches at the upper and lower ends that are clamped and fixed in the buckle grooves of the outer shell 220, which is convenient for installation without other tools.

[0058] In one embodiment, the end cap 230 and the outer shell 220 can be fixed by screwing.

[0059] In another embodiment, the end cap 230 and the ratchet bar 300 can be set as one body.

[0060] Refer to Figure 3 , as a further solution, to solve the problem of the fixation of the ratchet bar 300 in the installation cavity 221, the cavity wall of the installation cavity 221 is provided with a limiting portion 222, and the ratchet bar 300 is provided with an installation portion 330 that matches the limiting portion 222. The limiting portion 222 and the installation portion 330 cooperate to fix the ratchet bar 300 in the installation cavity 221.

[0061] In one embodiment, the left and right side walls of the installation cavity 221 are provided with card slots, and the ratchet bar 300 is provided with buckles. By inserting the buckles into the card slots and through the cooperation of the end cap 230, the ratchet bar 300 is fixed.

[0062] In another embodiment, the ratchet bar 300 is fixed in the installation cavity 221 by screwing.

[0063] In yet another embodiment, the ratchet bar 300 is fixed in the installation cavity 221 by gluing.

[0064] As a further scheme, in order to make the installation of the ratchet 300 more convenient, the limiting part 222 is provided with a sliding groove 223, and the installation part 330 is placed in the sliding groove 223.

[0065] The upper and lower cavity walls of the installation cavity 221 are provided with limiting parts 222, the holding parts 350 of the ratchet 300 can be inserted into the sliding grooves 223 of the limiting parts 222, and the groove walls of the sliding grooves 223 are further provided with guide strips, the two ends of the holding parts 350 are provided with guide grooves corresponding to the guide strips, when installing, the holding parts 350 are held by hand, the two ends of the holding parts 350 are corresponded to the sliding grooves 223 of the limiting parts 222, and are pushed into the sliding grooves 233, the guide strips and the guide grooves can further play a guiding role in the moving direction of the holding parts 350, that is, the ratchet 300 can be installed in place, which is simple and convenient, and when the end cover 230 is covered on the shell 210, the end cover 230 is limited from the sliding grooves 223 of the ratchet 300, so that the ratchet 300 can be matched with the pawl 500, the installation is convenient, and the assembly is convenient.

[0066] As a further scheme, in order to solve the problem that the installation direction of the ratchet 300 is wrong, resulting in suspension failure, the ratchet 300 is provided with an installation mark 340 for indicating the installation direction.

[0067] The cooperation of the ratchet 300 and the pawl 500 makes the pipe fastener 410 move in one direction, and it is not difficult to understand that if the direction of the ratchet 300 is wrong, because the pawl 500 abuts against the positioning step 310, the pipe fastener 410 cannot move, that is, the pull-out faucet 100 cannot be pulled. Specifically, the installation mark 340 can be pasted or stamped on the surface of the ratchet 300, so that it can be distinguished during assembly, and installation errors can be avoided.

[0068] As a further scheme, in the prior art, the suspension position of the pull-out faucet 100 cannot be adjusted, and if the number of suspension segments needs to be increased, the structure of the rotating wheel is required to be high, and the motion trajectory is complex, so that it is basically difficult to realize multi-segment suspension. In order to solve the problem of multi-segment suspension, the side of the ratchet 300 facing the pipe passing cavity 224 is recessed to form a plurality of positioning steps 310 arranged in the height direction. For example, two positioning steps 310, three positioning steps 310, and the like, so as to realize multi-segment suspension, greatly facilitate the operation of the user, and avoid the problems that the faucet is pulled to suspend for too short, resulting in that the suspension setting does not work, or the faucet is pulled to suspend for too long, affecting the operation process.

[0069] Referring to Figures 3-9 , as a further scheme, in order to solve the problem of installation of the pawl 500 and facilitate the assembly of the suspension assembly 400, the outer wall of the pipe fastener 410 is provided with a pawl installation groove 420, and the rotating part 520 is placed in the pawl installation groove 420 and is fixed through the rotating shaft 430.

[0070] Referring to Figure 8 , specifically, the outer wall of the pipe fastener 410 is externally convexly formed with the pawl mounting groove 420, the rotating part 520 of the pawl 500 is fixed in the pawl mounting groove 420 through the rotating shaft 430, in order to make the pawl 500 separate from the positioning elastic sheet 700 when passing through the elastic reset part 800, so that the pawl 500 restores the initial state, that is, the pawl lower part 530 is abutted by the spring 600 and is inclined to rotate, when the positioning elastic sheet 700 clamps the pawl upper part 510, the collision point of the pawl lower part 530 with the elastic reset part 800 and the collision line 610 of the rotating shaft 430, the angle between the collision line 610 and the extension line 620 of the collision surface of the elastic reset part 800 is less than 90°, so that the pawl lower part 530 has a component force of rotating away from the pipe fastener 410 after colliding with the elastic reset part 800, so that the positioning elastic sheet 700 separates from the pawl upper part 510. In addition, in order to make the torque sufficient for the positioning elastic sheet 700 to separate from the pawl upper part 510, the length of the pawl lower part 530 is greater than the length of the pawl upper part 510, so as to increase the rotating torque of the pawl lower part 530. In addition, in order to avoid the elastic reset part 800 from clamping the pawl 500, the collision point of the pawl lower part 530 is close to the intersection of the guide arc surface of the elastic reset part 800. In addition, in order to ensure that the pawl lower part 530 can generate a component force towards the reset pin 810 when colliding with the elastic reset part 800, a collision guide surface can be arranged at the collision point of the pawl lower part 530, and further the pawl lower part 530 has a movement tendency towards the reset pin 810 after colliding.

[0071] As a further scheme, in order to solve the assembly problem of the elastic reset part 800, the elastic reset part 800 comprises a reset pin 810 and a reset spring 820, the shell 210 is provided with a reset cavity 225, the reset pin 810 is installed in the reset cavity 225, and the reset spring 820 is located between the reset pin 810 and the shell 210.

[0072] Specifically, the elastic reset part 800 further comprises a locking part 830, the reset pin 810 is arranged in the reset cavity 225 during installation, the reset spring 820 is located at the other end of the reset pin 810, the locking part 830 is threadedly connected with the cavity wall of the reset cavity 225, and the reset pin 810 is pressed tightly by rotating the locking part 830, so that the reset pin 810 can be extended to the pipe cavity 224 under the action of the spring, the locking part 830 is, for example, an internal angle bolt, and when the locking part 830 is rotated, the end of the locking part 830 is substantially flush with the outer wall of the shell 210, that is, the locking part 830 is installed in place.

[0073] The end of the reset pin 810 is arc-guided, when the claw upper part 510 is clamped by the positioning spring 700, and the claw lower part 530 is driven by the abutting spring 600, the pipe fastener 410 falls back to the original position along with the water pipe 110 under the action of the weight hammer 120, because the reset pin 810 extends in the pipe cavity 224, and the shape of the shell 210 restricts the circumferential rotation of the pipe fastener 410, the pulling release, the water pipe 110 continuously moves linearly downward under the action of the gravity hammer, at the moment when the claw lower part 530 collides with the reset pin 810 at the collision point, the claw lower part 530 is separated from the reset pin 810, at this time, the claw upper part 510 makes the positioning spring 700 deform under the action force, the claw upper part 510 passes through the positioning spring 700 to make the pawl 500 complete reset, and the arc segment of the arc-guided reset pin 810 can make the reset pin 810 move into the reset cavity 225 under the action of the impact force, so that the pipe fastener 410 can pass through the reset pin 810, and the reset pin 810 can also be pressed to move in the next pull-out faucet 100.

[0074] In other embodiments, the elastic reset member 800 can be a spring embedded in the inner wall of the pipe cavity 224 of the shell 210, or a spring steel ball embedded and installed.

[0075] As a further solution, in order to facilitate the installation of the abutting spring 600, the outer wall of the pipe fastener 410 is provided with a spring mounting seat 440, one end of the abutting spring 600 is mounted in the spring mounting seat 440, and the other end is exposed outside the spring mounting seat 440. The spring mounting seat 440 protrudes outwardly from the outer wall of the pipe fastener 410, and is in the shape of a circular ring. When installing, one end of the abutting spring 600 is inserted, and the spring is fixed by interference fit or gluing. When the claw lower part 530 abuts against the abutting spring 600, the abutting spring 600 will give an opposite force, ensuring that the pawl 500 can be clamped on the positioning step 310 after reaching the ratchet 300, realizing the hovering of the pull-out faucet 100. Because only the abutting spring 600 needs to be fixed during installation, the installation is convenient, and the assembly steps are simple.

[0076] In other embodiments, the abutting spring 600 can be connected to the outer wall of the pawl 500 and the pipe fastener 410, respectively.

[0077] In order to solve the problem of the compression stroke direction of the abutting spring 600, the spring mounting seat 440 is further provided with a limiting column 450 located in the abutting spring 600. The limiting column 450 is located in the spring ring of the abutting spring 600, which can guide the compression process of the abutting spring 600 to a certain extent, avoiding the bending and compression of the abutting spring 600 when it is subjected to the action force of the pawl 500, and causing the spring force to decrease.

[0078] The problem that the existing pull water pipe 110 needs to be always applied to the water pipe 110 is solved by connecting the shell 210, the pipe fastener 410 and the water pipe 110, the outer wall of the pipe fastener 410 is rotationally connected with the pawl 500, the pawl 500 is selectively clamped in different positioning steps 310 on the shell 210 by moving the pipe fastener 410 driven by the water pipe 110, so as to realize hovering, the reset of the water pipe 110 through the positioning step 310 is realized by the cooperation of the positioning spring 700 and the pawl 500, and the pawl 500 can be restored to the original position by the action of the elastic reset member 800.

[0079] In order to solve the installation problem of the positioning spring 700, the outer wall of the pipe fastener 410 is also provided with a spring fixing portion 460, one end of the positioning spring 700 is clamped on the spring fixing portion 460, and the other end is provided with a clamping protrusion 710 capable of clamping the claw upper portion 510. The spring fixing portion 460 is like a box with a side opening, and the positioning spring 700 is in the shape of “Z”. When installing, one end is clamped into the spring fixing seat to realize the fixation of the positioning spring 700, which is simple and convenient. The end of the positioning spring 700 close to the claw upper portion 510 and the claw upper portion 510 form a matching protrusion, the positioning spring 700 forms a V-shaped clamping protrusion 710, so that the claw lower portion 530 passes through the abutting protrusion 320, the protrusion of the claw upper portion 510 can pass through the clamping protrusion 710 of the positioning spring 700 and be limited by the positioning spring 700, the acting force of the positioning spring 700 is greater than the acting force of the abutting spring 600, so as to avoid the rotation of the claw lower portion 530, so that the water pipe 110 can be restored to the original position under the driving of the weight 120.

[0080] In other embodiments, the positioning spring 700 can be fixed by screw locking, gluing, injection molding and embedding.

[0081] Referring to Figure 3 In order to make the pipe fastener 410 move smoothly towards the pipe cavity 224 of the shell 210, avoid jamming, the inner wall of the pipe cavity 224 of the shell 210 towards the cavity of the guide protrusion 470 is also provided with a guide ring groove 226 matched with the guide protrusion 470. The inner wall openings of the two ends of the pipe cavity 224 of the shell 210 are in the shape of a tapered horn, the outer wall of the pipe fastener 410 is also provided with a guide protrusion 470, the cross-sectional shape of the guide protrusion 470 is triangular, the guide protrusion 470 and the guide ring groove 226 are matched in direction, so that the pulling of the water pipe 110 is more smooth and the positioning is more accurate.

[0082] The application further provides a pull-out faucet 100, which comprises a water pipe 110 and a pull-out suspension mechanism 200, the specific structure of which is referred to the above-mentioned embodiments.

The pipe fastener 410 is fastened to the outer wall of the water pipe 110, and the water pipe 110 passes through the pipe passing cavity 224 of the shell 210. When the water pipe 110 is in the initial state, the elastic reset member 800 is in contact with the claw lower part 530. When the water pipe 110 is pulled out and in the suspension state, the operator does not need to exert force on the water pipe 110, so as to release the hand to perform other operations or work, which is convenient for use. When it is needed to recover the water pipe 110, the water pipe 110 is continuously pulled out, and after the sensing positioning elastic sheet 700 is clamped with the claw upper part 510, the hose is released, and the hose can fall to the initial position under the action of the weight 120 arranged at the bottom of the hose. When the claw lower part 530 touches the elastic reset member 800, the claw lower part 530 generates an action force away from the hose, so that the claw upper part 510 and the positioning elastic sheet 700 are in the clamped state, the pawl 500 is restored to the free state, so as to continue to realize the suspension when the hose is pulled out next time. In the whole hose pulling process, whether it is suspension or reset, it does not need to be manually realized, and automatic suspension and reset can be realized.
