Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom appliances, in particular to a pull-out and hovering structure and a water outlet device. Background Art

[0002] A pull-out faucet refers to a product in which the water outlet head can be pulled out a certain distance from the faucet body during use. A counterweight is provided at the other end of the water pipe connecting the water outlet nozzle, so that when the pull-out faucet is not in use, it can be reset under the action of the gravity of the counterweight. Due to the setting of the counterweight, in some existing technologies, when using a pull-out faucet, the user must constantly apply a pulling force to the faucet to overcome the gravity of the counterweight and thus keep it in a state of being pulled out from the faucet body, which is extremely inconvenient. In some other existing technologies, in order for the user to free both hands, some fixed hovering points are provided inside the hovering structure of the faucet, so that the pull-out head can be fixed and hovered when it is pulled out to this position. However, the method of presetting the hovering points cannot meet the user's various requirements for different hovering positions. At the same time, if multiple hovering positions are to be achieved, the number of hovering points needs to be continuously increased, which will make the hovering structure more complex. Summary of the Invention

[0003] The utility model provides a pull-out and hovering device, aiming to solve the problem that the pull-out faucet in the existing technology cannot meet the user's various requirements for different hovering positions.

[0004] To achieve the above object, an embodiment of the first aspect of the utility model provides a pull-out and hovering device, including:

[0005] A housing, in which a first channel and a first guiding part are arranged, and the first channel is used for a water pipe to pass through;

[0006] A first rolling member, which is rotatably arranged in the first guiding part. When the water pipe passes through the first channel, the projections of the water pipe and the first rolling member along the axial direction of the first channel coincide or at least partially overlap;

[0007] A positioning member, which is arranged in the housing and on the side of the first channel facing away from the first guiding part;

[0008] When the first rolling member rolls to a first position in the first guiding part, the projections of the positioning member and the first rolling member in the horizontal direction at least partially coincide, so as to squeeze the water pipe to make the pipeline assembly hover.

[0009] According to some embodiments of the utility model, the distance between the side of the first guiding part away from the first channel and the first channel gradually decreases downward.

[0010] According to some embodiments of the present utility model, the positioning member is a second rolling member, the second rolling member is fixedly arranged in the shell, and can rotate around the axis of the second rolling member;

[0011] The drawing and hovering device further includes a lifting frame and a first spring, the lifting frame and the first spring are both arranged in the shell, wherein one end of the first spring abuts against the inner wall of the shell, and the other end pushes against one side of the lifting frame, so that the other side of the lifting frame abuts against the second rolling member to limit the rotation of the second rolling member.

[0012] According to some embodiments of the present utility model, a supporting foot is further arranged at one end of the lifting frame close to the second rolling member. When the lifting frame abuts against the second rolling member, the supporting foot passes through the shell downward and part of it is exposed outside the shell. Among them, when the supporting foot is driven, the lifting frame moves upward.

[0013] According to some embodiments of the present utility model, a first engaging component is further arranged on the lifting frame, and a second engaging component is arranged in the shell. Among them, during the drawing process of the water pipe, when the lifting frame is driven to move upward to the second position, the first engaging component and the second engaging component are engaged to position the lifting frame at the second position.

[0014] According to some embodiments of the present utility model, the first engaging component includes a clamping strip and a second spring. One end of the second spring abuts against the inner wall of the shell, and the other end abuts against the clamping strip. A first notch is arranged on one side of the clamping strip close to the second engaging component;

[0015] The second engaging component includes a clamping block extending downward from the inner wall of the shell. The clamping block is arranged in the first notch and abuts against one side of the first notch. A second notch is arranged on one side of the clamping block facing the clamping strip

[0016] According to some embodiments of the present utility model, a third rolling member is further included. The axis of the third rolling member is perpendicular to the axis of the first channel. Among them, a first tooth surface is arranged on one side of the third rolling member close to the second spring;

[0017] A reset member, the reset member includes a second tooth surface and a lever. Among them, the first tooth surface and the second tooth surface are meshed and connected, so that the third rolling member drives the reset member to rotate unidirectionally during rotation. When the reset member rotates, the lever pushes the clamping strip to reset so that the first engaging component and the second engaging component are no longer engaged.

[0018] According to some embodiments of the present utility model, a third spring is further included. One end of the third spring abuts against the inner wall of the housing, and the other end abuts against a side of the reset member facing away from the second tooth surface.

[0019] According to some embodiments of the present utility model, a second guiding portion is provided on a side of the clamping strip close to the reset member. When the reset member rotates, the lever pushes against the guiding portion to reset the clamping strip.

[0020] According to some embodiments of the present utility model, a pushing block is provided on a side of the lifting frame close to the third rolling member. When the lifting frame moves upward to the second position, the pushing block pushes against the third rolling member, causing the third rolling member to change from a separated state from the water pipe to an abutting state with the water pipe.

[0021] For the draw-out and hovering device according to some embodiments of the present utility model, a first channel for the water pipe to pass through is provided in the housing. The first rolling member is rotatably arranged in the first guiding portion in the housing. When the water pipe passes through the first channel, the projections of the water pipe and the first rolling member along the axial direction of the first channel are fitted or at least partially overlapped. The positioning member is arranged in the housing and on a side of the first channel facing away from the first guiding portion. Thus, the user can let go after moving the draw-out faucet to any position. At this time, the first rolling member rolls to the first position in the first guiding portion. At this time, the projections of the positioning member and the first rolling member in the horizontal direction are at least partially overlapped to squeeze the water pipe to make the pipeline assembly hover, without the user having to keep applying force with the hand to overcome the gravity of the counterweight to maintain the hovering position, nor having to preset a hovering point for the draw-out faucet. The draw-out and hovering device can hover steplessly at any position, simplifying the hovering mechanism and being convenient and labor-saving to use.

[0038] 3000、Counterweight DETAILED DESCRIPTION

[0039] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0040] refer to Figure 1 In some specific embodiments of the utility model, a pull-out suspension device 1000 is provided, which can be applied to scenes such as bathroom showers or kitchen water use. For example, the pull-out suspension device 1000 can be applied to the inside of products such as shower heads and water faucets, and used in conjunction with a pipeline assembly, wherein the pipeline assembly can include a pull-out head (not shown), a water pipe 2000, and a counterweight block 3000. When the user operates the pull-out head to move to any use position, the pull-out suspension device 1000 can fix the water pipe 2000 so that it overcomes the gravity of the counterweight block 3000 to suspend in the use position. At this time, the user can release the pull-out head without having to keep the pulling force on the pull-out head, which is very convenient to use. The following takes the pull-out suspension device 1000 applied to a water faucet (including a pipeline assembly) as an example to illustrate some embodiments of the utility model.

[0041] refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of the present invention, the pull-out suspension device 1000 includes a housing 1100, a first rolling member 1210 and a positioning member, wherein a first channel 1120 and a first guide portion 1110 are provided in the housing 1100, and the first channel 1120 is used for the water supply pipe 2000 to pass through. Specifically, the top wall and the bottom wall of the housing 1100 are provided with tube holes, and the space inside the housing 1100 that can accommodate the water pipe 2000 constitutes the first channel 1120, and the water pipe 2000 passes through the two tube holes and the internal space of the housing 1100 to be inserted into the pull-out suspension device 1000.

[0042] The first rolling member 1210 is disposed within the first guiding portion 1110 and can roll within the first guiding portion 1110. When the water pipe 2000 is passed through the first channel 1120, the axial projection of the water pipe 2000 and the first rolling member 1210 at least partially overlap or fit. Specifically, two opposite plate members extend upward from the bottom wall of the housing 1100, and first guide grooves (not shown) with the same contour are hollowed out on both plate members. The two opposite first guide grooves constitute the first guiding portion 1110. The first rolling member 1210 can be a roller, a roller shaft, or a drum. One side of the first rolling member 1210 is rotatably mounted on one of the first guide grooves, and the other side is mounted on the other first guide groove. Thus, the rolling member is rotatably disposed on the first guiding portion 1110. Therefore, when the water pipe 2000 is passed through the first channel 1120, due to the action of gravity, the first rolling member 1210 has a downward movement tendency, so that the outer peripheral wall of the first rolling member 1210 is kept in contact with the outer wall of the water pipe 2000.

[0043] The positioning member is disposed within the housing 1100. Specifically, the positioning member is located on the side of the first channel 1120 facing away from the first guiding portion 1110. Refer to Figure 7 , when the water pipe 2000 is reset downward, the outer wall of the water pipe 2000 provides a frictional force to the first rolling member 1210 to cause the first rolling member 1210 to roll downward. When the first rolling member 1210 rolls to the first position, the projections of the positioning member and the first rolling member 1210 in the horizontal direction overlap or at least partially overlap, so as to squeeze the water pipe 2000 to make the pipe assembly hover.

[0044] It can be understood that the first position can be multiple different positions. For example, when the plane where the axis of the first rolling member 1210 and the axis of the positioning member are located is perpendicular to the axis of the first channel 1120, the position where the first rolling member 1210 is located is the first position. It can also be when the above plane is not perpendicular to the axis of the first channel 1120, the position where the first rolling member 1210 is located is the first position. At this time, the positioning member only needs to overlap or at least partially overlap with the projection of the first rolling member in the horizontal direction to squeeze the water pipe 2000, and the pipe assembly can be made to hover.

[0045] Through this embodiment, the user can release the pull-out faucet at any position after pulling it and achieve hovering, without the user having to continuously use their hand to overcome the gravity of the counterweight 3000. At the same time, there is no need to preset hovering points so that the pull-out faucet has multiple preset hovering positions.

[0046] Refer to Figure 3, in some embodiments of the present utility model, the distance between the side of the first guiding portion 1110 away from the first channel 1120 and the first channel 1120 gradually decreases downward. Specifically, the first sides 1111 of the two first guide grooves away from the first channel 1120 are inclined relative to the first channel 1120. It can be understood that if the side of the first guide groove away from the first channel 1120 is extended, the included angle between the extension line and the axis of the first channel 1120 is an acute angle.

[0047] Thus, when the user pulls the water pipe 2000 upward, the water pipe 2000 can drive the first rolling member 1210 to roll in the same direction along the first guiding portion 1110. At this time, due to the inclined arrangement of the first side 1111 of the first guide groove away from the first channel 1120, the first rolling member 1210 has a moving space away from the water pipe 2000, reducing the degree of extrusion on the water pipe 2000. Therefore, when the user pulls the water pipe 2000, it can be more labor-saving and easy.

[0048] It can be understood that the second sides 1112 of the two first guide grooves close to the first channel 1120 can also be inclined relative to the first channel 1120.

[0049] Reference Figure 2 、 Figure 3 、 Figure 4 and Figure 7 , in some embodiments of the present utility model, the positioning member is the second rolling member 1220. The second rolling member 1220 can be a roller, a roller shaft or a drum. Both ends of the second rolling member 1220 are fixedly arranged in the housing 1100 and can rotate relative to the housing 1100 around the axis of the second rolling member 1220. The pulling and hovering device 1000 further includes a lifting frame 1300 and a first spring 1410 both arranged in the housing 1100. One end of the first spring 1410 abuts against the inner wall of the housing 1100, and the other end pushes against one side of the lifting frame 1300 downward. The lifting frame 1300 is under the elastic force of the first spring 1410, and the side away from the first spring 1410 abuts against the second rolling member 1220, thereby realizing the rotation restriction of the second rolling member 1220.

[0050] Further, referring to Figure 4 , a second positioning hole 1330 is arranged on the side of the lifting frame 1300 facing the first spring 1410. One end of the first spring 1410 close to the lifting frame 1300 is arranged in the second positioning hole 1330 to realize the limit, avoiding the relative sliding of the first spring 1410 relative to the lifting frame 1300 and unable to achieve good pushing.

[0051] Due to the restriction of the lifting frame 1300 on the second rolling member 1220, when the second rolling member 1220 moves on the water pipe 2000, it cannot rotate due to the frictional force between the second rolling member 1220 and the water pipe 2000, and the friction between them is sliding friction. Therefore, when the first rolling member 1210 moves to the first position, both the first rolling member 1210 and the second rolling member 1220 squeeze the water pipe 2000 and make it hover. At this time, the second rolling member 1220 and the first rolling member 1210 jointly provide a frictional force to the water pipe 2000, which can better restrict the movement of the water pipe 2000 and ensure stable hovering.

[0052] Reference Figure 2 、 Figure 3 and Figure 4 In some embodiments of the present invention, a support leg 1310 is further provided on the side of the lifting frame 1300 close to the second rolling member 1220. When the lifting frame 1300 abuts against the second rolling member 1220 under the elastic force of the first spring 1410, the support leg 1310 passes downward through the bottom wall of the housing 1100, and at least part of the support leg 1310 is exposed outside the housing 1100. Specifically, a through hole for the support leg 1310 to pass through is provided on the bottom wall of the housing 1100. When the support leg 1310 is inserted into the through hole and moves in the through hole, it can guide the lifting frame 1300 to always face the second rolling member 1220 to ensure a good abutting effect.

[0053] Further, referring to Figure 4 and Figure 9 A plurality of guide ribs 1350 may be provided on the lifting frame 1300, and a plurality of guide chutes 1140 are provided on the housing 1100. The lifting frame 1300 and the housing 1100 can be slidably connected through the guide ribs 1350 and the guide chutes 1140. Thus, the movement process of the lifting frame 1300 is further guided well to avoid tilting and jamming.

[0054] Reference Figure 8 and Figure 9 The support leg 1310 can be driven by the pipeline assembly to move upward. Specifically, it means that when the pipeline assembly is pulled upward to contact the support leg 1310 and continues to move upward, it can drive the support leg 1310 to move in the same direction. At this time, the lifting frame 1300 also moves upward. It can be understood that the pipeline assembly may include the water pipe 2000 and the counterweight 3000. During the pulling process, when the counterweight 3000 moves, it pushes against the support leg 1310 to make the lifting frame 1300 move in the same direction. It can also be that both the support leg 1310 and the counterweight 3000 are made of magnetic materials, and the magnetic properties of the opposite sides of the support leg 1310 and the counterweight 3000 are the same. Thus, when the counterweight 3000 moves, the lifting frame 1300 is driven to move in the same direction by magnetic repulsion.

[0055] It can be understood that the pipeline assembly may also only include the water pipe 2000. Among them, a protrusion, such as a convex ring or an annular rib, is provided on the side of the water pipe 2000 facing downward and away from the pulling and hovering assembly. During the pulling process, the protrusion pushes against the support leg 1310 to move the lifting frame 1300 in the same direction. It is also possible that both the support leg 1310 and the protrusion are made of magnetic materials, and the magnetic properties of the sides of the support leg 1310 and the protrusion facing each other are the same. Thus, when the pipeline assembly moves, the protrusion causes the lifting frame 1300 to move in the same direction through repulsive force.

[0056] The following takes the pipeline assembly including the water pipe 2000 and the counterweight 3000 as an example (the water pipe 2000 is in contact with the first rolling member 1210 and the second rolling member 1220) to further illustrate this embodiment: When the user pulls the water-using assembly to change the hovering position, the water pipe 2000 moves upward. The first rolling member 1210 is affected by the frictional force of the water pipe 2000 and also rolls upward. The first rolling member 1210 and the second rolling member 1220 can no longer squeeze the water pipe 2000 to make it hover (such as Figure 3 ). Before the counterweight 3000 drives the lifting frame 1300, there is a rolling frictional force between the first rolling member 1210 and the water pipe 2000, and a sliding frictional force between the second rolling member 1220 and the water pipe 2000. At this time, the pulling feel is not good. When the counterweight 3000 starts to drive the lifting frame 1300 to move, the lifting frame 1300 no longer abuts against the second rolling member 1220, and the second rolling member 1220 can rotate. Thus, the sliding frictional force between the water pipe 2000 and the second rolling member 1220 is transformed into a rolling frictional force. At this time, it is more labor-saving and the feel is better when pulling. When reaching the hovering position, the user releases the hand, and the water pipe 2000 moves downward due to the pulling force of the counterweight 3000. At this time, it drives the first rolling member 1210 to move downward, and at the same time, the second rolling member 1220 also rotates. When resetting to the position where the counterweight 3000 no longer drives the support leg 1310, the lifting frame 1300 resumes the rotational restriction on the second rolling member 1220. At this time, the second rolling member 1220 no longer rotates, and the rolling friction between it and the water pipe 2000 is transformed into sliding friction until the first rolling member 1210 reaches the first position. At this time, the first rolling member 1210 and the second rolling member 1220 re-squeeze the water pipe 2000 to achieve hovering (such as Figure 7 ).

[0057] In some embodiments of the present utility model, a first engaging component is provided on the lifting frame 1300, and a second engaging component is provided inside the housing 1100. When the lifting frame 1300 is driven by the pipeline component and moves upward to the second position, the first engaging component and the second engaging component abut against each other to limit the lifting frame 1300 at the second position. Specifically, one of the first engaging component and the second engaging component may be a groove, and the other is composed of a pin and a spring. During the process of the lifting frame 1300 moving to the second position (before reaching the second position), the pin and the spring are squeezed. When the lifting frame 1300 moves to the second position instantaneously, the pin is opposite to the groove. At this time, the pin moves into the groove under the action of the spring force to complete the clamping, thereby restricting the movement of the lifting frame 1300.

[0058] Reference Figure 2 , Figure 6 , Figure 9 and Figure 10 , in some embodiments of the present utility model, the first engaging component includes a clamping strip 1500 and a second spring 1420. One end of the second spring 1420 abuts against the inner wall of the housing 1100, and the other end abuts against the clamping strip 1500. The clamping strip 1500 is provided on the lifting frame 1300 and can move backward relative to the lifting frame 1300. It can be understood that, without obstruction, the clamping strip 1500 can move backward under the action of the elastic force of the second spring 1420. A first notch 1510 is provided on the side of the clamping strip 1500 close to the second engaging component.

[0059] Further, referring to Figure 6 and Figure 10 , a first positioning hole 1530 is provided at one end of the clamping strip 1500 close to the second spring 1420, and one end of the second spring 1420 close to the clamping strip 1500 is arranged in the first positioning hole 1530 to achieve stable abutment against the clamping strip 1500 and avoid sliding.

[0060] Further, referring to Figure 4 , a card slot 1340 can be provided on the lifting frame 1300, and the clamping strip 1500 is slidably arranged in the card slot 1340.

[0061] The second engaging assembly includes a block 1130 extending downward from the inner wall of the housing 1100 . The block 1130 and the clamping strip 1500 are in contact with each other. A second notch 1131 is provided on a side of the block 1130 facing the clamping strip 1500 . When the lifting frame 1300 moves upward gradually to the second position, the block 1130 and the card strip 1500 abut. Specifically, the main part of the block 1130 (excluding the second notch 1131) is inserted into the first notch 1510 of the card strip 1500. At this time, because the main body of the block 1130 abuts against one side of the first notch 1510 of the card strip 1500 in a direction perpendicular to the moving direction of the lifting frame 1130, the card strip 1500 overcomes the elastic force of the second spring 1420 and does not move backward, but only moves upward with the movement of the lifting frame 1300. At this time, the card strip 1500 slides relative to the block 1130. When the lifting frame 1300 moves to the second position, the first notch 1510 and the second notch 1131 intersect. At this time, due to the elastic force of the second spring 1420, the card strip 1500 moves backward, and the first notch 1510 and the second notch 1131 are staggered, so that the card strip 1500 The main body (excluding the portion of the first notch 1510) is engaged in the second notch 1131, thereby preventing the lifting frame 1300 from moving upwards any further. The lifting frame 1300 is in a limited position state, so that the pipeline assembly cannot be pulled upwards without restriction and damage the pull-out suspension device 1000. At the same time, due to the limitation of the lifting frame 1300, the second rolling member 1220 is always in a rotatable state. Therefore, when the user releases the water pipe 2000, the water pipe 2000 moves downwards due to the pulling force of the counterweight block 3000. At this time, even if the first rolling member 1210 moves to the first position, the second rolling member 1220 can rotate under the friction between the water pipe 2000. At this time, the first rolling member 1210 and the second rolling member 1220 cannot clamp the water pipe 2000. Therefore, the pipeline assembly can freely move downwards and thus return to a non-suspended state, that is, the pull-out suspension device 1000 is reset.

[0062] refer to Figure 2 , Figure 5 , Figure 9 and Figure 10In some embodiments of the present invention, the pull-out suspension device 1000 further includes a third rolling member 1230 and a reset member 1600. Specifically, the third rolling member 1230 may also be a roller, a roller shaft or a drum, and the axis of the third rolling member 1230 is perpendicular to the axis of the first channel 1120 and parallel to the moving direction of the card strip 1500 in the lifting frame 1300, wherein the third rolling member 1230 is provided with a first tooth surface 1231 on one side close to the second spring 1420. The reset member 1600 includes a second tooth surface 1620 and a lever 1610, wherein the first tooth surface 1231 and the second tooth surface 1620 are meshed, so that the third rolling member 1230 can drive the reset member 1600 to rotate unidirectionally during the rotation process. When the reset member 1600 rotates, the lever 1610 can push the clamping bar 1500 to overcome the elastic force of the second spring 1420 and move in the direction opposite to the rear, thereby completing the reset of the clamping bar 1500 and making the first clamping assembly and the second clamping assembly disengage the clamping state, so that the limiting state of the lifting frame 1300 is released.

[0063] Specifically, refer to Figure 5 The first tooth surface 1231 and the second tooth surface 1620 both have a sliding surface and a stop surface. When the third rolling element 1230 rotates along the first rotation direction, the stop surface of the first tooth surface 1231 and the stop surface of the second tooth surface 1620 abut against each other, and the third rolling element 1230 can drive the reset element 1600 to move, thereby driving the lever 1610 to push the clamping strip 1500 to move. When the third rolling element 1230 rotates along the second rotation direction, the sliding surfaces between the first tooth surface 1231 and the second tooth surface 1620 abut against each other and slip during the relative rotation, so that the third rolling element 1230 and the reset element 1600 slip, and the third rolling element 1230 cannot drive the reset element 1600.

[0064] refer to Figure 2 , Figure 9 and Figure 10 In some embodiments of the present invention, a third spring 1430 is further included, one end of the third spring 1430 abuts against the inner wall of the housing 1100, and the other end abuts against the side of the reset member 1600 facing away from the second tooth surface 1620. The elastic force of the third spring 1430 pushes against the second tooth surface 1620 of the reset member 1600 and the first tooth surface 1231 of the third rolling member 1230 to always keep in contact during the rotation process, thereby preventing the reset member 1600 from being separated during the rotation process, resulting in the third rolling member 1230 being unable to drive the reset member 1600 to rotate.

[0065] Furthermore, an axial hole is provided on one of the third rolling member 1230 and the reset member 1600, and a convex shaft is provided on the other one. The third rolling member 1230 and the reset member 1600 are rotatably connected via the axial hole and the convex shaft to maintain alignment.

[0066] Reference Figure 6 、 Figure 9 and Figure 10 In some embodiments of the present utility model, on the side of the latch strip 1500 close to the reset member 1600, a second guiding portion 1520 is further provided. The second guiding portion 1520 is located at one end of the latch strip 1500 close to the second spring 1420 and is disposed opposite to the reset member 1600. When the third rolling member 1230 drives the reset member 1600 to rotate, the lever 1610 can rotate synchronously with the rotation of the reset member 1600. When the lever 1610 abuts against the second guiding portion 1520 and continues to rotate, the latch strip 1500 can be moved in the direction of the second spring 1420, so that the main body portion of the latch strip 1500 disengages from the second notch 1131 of the latch block 1130, and the main body portion of the latch block 1130 returns to the first notch 1510 on the latch strip 1500 again, so that the two are disengaged from the mutually engaged position. Thus, the limiting state of the lifting frame 1300 is released. In this state, under the elastic force of the first spring 1410, the lifting frame 1300 moves downward until it abuts against the second rolling member 1220 again to stop its rotation.

[0067] Reference Figure 2 、 Figure 3 and Figure 4 In some embodiments of the present utility model, a pushing block 1320 is provided on the side of the lifting frame 1300 close to the third rolling member 1230. When the lifting frame 1300 gradually moves upward to the second position, the pushing block 1320 pushes against the third rolling member 1230, causing the third rolling member 1230 to change from a mutually separated state to a mutually abutting state with the water pipe 2000.

[0068] Reference Figure 2 、 Figure 4 and Figure 9 The side of the pushing block 1320 facing the third rolling member 1230 is a pushing inclined surface 1321. On the latch block 1130, an inclined sliding groove 1132 for the third rolling member 1230 to be disposed therein is provided. One end of the inclined sliding groove 1132 is close to the pushing inclined surface 1321, and the other end is close to the pipe assembly. The third rolling member 1230 can be driven to move in the inclined sliding groove 1132. Specifically, through the pushing inclined surface 1321, the pushing block 1320 can push against the third rolling member 1230 to move in the inclined sliding groove 1132 during the movement. It can be understood that before the lifting frame 1300 moves upward to the second position, the pushing block 1320 pushes against the third rolling member 1230 to move in the inclined sliding groove 1132. At this time, the third rolling member 1230 is not in contact with the water pipe 2000. When the lifting frame 1300 moves to the second position, the third rolling member 1230 moves to a position where it can be in contact with the water pipe 2000.

[0069] Next, taking the embodiment of the present utility model as an example, the working process and principle of the pull-out hovering device 1000 will be described in detail:

[0070] When the user needs to drive the pull-out water outlet head away from the faucet body and hover at a certain position, the pull-out water pipe 2000 moves upward. At this time, the first rolling member 1210 moves upward in the first guiding portion 1110 under the frictional force of the water pipe 2000 ( Figure 3 ). After reaching the hovering position, the pull-out water outlet head is released, and the water pipe 2000 moves downward under the gravity of the counterweight 3000. At this time, the water pipe 2000 applies a frictional force to the first rolling member 1210 to make it move downward, while the second rolling member 1220 does not rotate under the pushing of the lifting frame 1300 until the first rolling member 1210 reaches the first position. The first rolling member 1210 and the positioning member squeeze the water pipe 2000 and clamp the water pipe 2000 to hover ( Figure 7 ).

[0071] When the user needs to reset after using the pull-out faucet, the user continues to pull the water pipe 2000 to move upward until the counterweight 3000 pushes against the support leg 1310, causing the lifting frame 1300 to move upward, thereby releasing the restriction on the rotation of the second rolling member 1220. Until the lifting frame 1300 reaches the second position, the first engaging assembly and the second engaging assembly are engaged, so that the lifting frame 1300 is limited and no longer moves relative to the pull-out hovering device 1000. During this process, the third rolling member 1230 also slides along the inclined sliding groove 1132 under the pushing of the pushing block 1320 until it abuts against the outer wall of the water pipe 2000 ( Figure 8 and Figure 9 ). At this time, the user releases the pull-out faucet, and the water pipe 2000 moves downward under the gravity of the counterweight 3000, driving the first rolling member 1210 to move downward. At this time, even if the first rolling member 1210 reaches the first position, since the rotation restriction of the second rolling member 1220 is released, it can rotate under the frictional force of the water pipe 2000. At this time, the first rolling member 1210 and the second rolling member 1220 cannot squeeze to make the water pipe 2000 hover, and the water pipe 2000 keeps moving downward to reset until the pull-out faucet is re-joined with the faucet body, thus completing the reset. During this process, the third rolling member 1230 is driven by the water pipe 2000 to rotate in the second rotation direction, and the first tooth surface 1231 and the second tooth surface 1620 slip, and the reset member 1600 does not rotate.

[0072] When the user uses the pull-out faucet next time and pulls the water pipe 2000 upward, during the upward movement of the water pipe 2000, the water pipe 2000 applies a frictional force to the third rolling member 1230, causing the third rolling member 1230 to rotate in the first rotation direction. Through the cooperation of the first tooth surface 1231 and the second tooth surface 1620, the reset member 1600 and its lever 1610 rotate. The lever 1610 pushes against the second guiding portion 1520 on the latch 1500, separating the first engaging assembly and the second engaging assembly, thereby releasing the limit of the lifting frame 1300. Under the elastic force of the first spring 1410, the lifting frame 1300 moves downward until it abuts against the second rolling member 1220 to restrict its rotation again. Thus, after reaching the target hovering position and releasing the pull-out water head again, hovering can be achieved, and the process of steplessly adjusting and hovering can also be repeated.

[0073] Thus, the user can achieve stepless adjustment and hovering during the use of the pull-out faucet, which is convenient to use, and the reset operation is simple and fast.
