As a preferred embodiment, the moving member 9 includes a slider 91 and a moving member integrally formed with or connected to the slider 91, the slider 91 being slidably engaged with the linear groove 511, the moving member being slidably engaged with the track groove 61. The movable member is in particular, but not limited to, a cylinder 92 having an axial direction parallel to the axial direction of the wheel 6, and in other embodiments, the movable member is a ball. The slider 91 is made of plastic material, so as to avoid overweight of the slider 91. The sliding block 91 and the movable part (i.e. the cylinder 92) on the sliding block solve the problems that the movable part 9 in the prior art adopts balls, which have very high requirements on processing precision, are inconvenient to install the balls, are easy to fall off, and the like. In other embodiments, the slider and the movable member thereon may be replaced with balls, regardless of the machining precision and portability of the installation. The slider 91 is provided with a long relief hole 911 for avoiding the bottom bracket 512, and the extending direction of the relief hole 911 coincides with the extending direction of the linear groove 511.
One end of the pull rope 8 is fixedly connected with the heavy hammer 4, specifically, one end of the pull rope 8 is tied to a clamping block 10, and the clamping block 10 is placed in the heavy hammer 4. As shown in fig. 8, a space and a through hole with the same diameter as the pull rope 8 exist in the clamping block 10, one end of the pull rope 8 passes through the through hole with the same diameter and then is knotted and locked in the space, and the connection part of the pull rope 8 is ensured to be clung to the drawing hose 3 as much as possible, namely, to be close to the axis 512 line of the heavy hammer 4.
The shell 5 is fixedly connected to the device body (i.e. the tap body 2) and is positioned above the heavy hammer 4, i.e. the shell 5 is sleeved outside the bottom of the tap body 2 by adopting a mounting ring 53 thereof, and is limited by a mounting nut 20 at the bottom of the tap body 2.
In operation, as shown in fig. 9, when the user starts to pull the pull-out nozzle 1, the pull-out hose 3 and the weight 4 move upward, and at this time, the rotating wheel 6 is rotated in the first direction (i.e., clockwise direction) only by the elastic potential energy of the coil spring 7, thereby recovering the pull cord 8. Since the cylinder 92 is constrained within the track groove 61, the cylinder 92 can only move in a second direction (i.e., counterclockwise) relative to the wheel 6. In the process, the cylinder 92 will eventually enter the inner tank 611 for infinite counterclockwise movement, no matter where the track tank is located.
When the user pulls the pull nozzle 1 to a required water outlet height position, as shown in fig. 10, after the user loosens the hands, the pull hose 3 is retracted, the heavy hammer 4 falls down for a small distance, in the process, the gravity of the heavy hammer 4 received by the pull rope 8 is far greater than the elastic force of the coil spring 7 due to the falling of the heavy hammer 4, so that the rotating wheel 6 rotates along the second direction to realize paying-off; the cylinder 92 originally moves in the inner groove 611 along the second direction, and as the rotating wheel 6 rotates in a reversing manner (from the first direction to the second direction), the cylinder 92 starts to move reversely (i.e. along the first direction), and when the cylinder 92 moves to the first far axis point 6111, the cylinder 92 directly enters the stop section 613 under the guidance of the outer side surface of the first far axis point 6111 to reach the stop position 6131, so that the rotating wheel 6 is blocked by the cylinder 92, the rotating wheel 6 stops rotating, and the pull rope 8 is paid off only for a small distance, and then the paying off is stopped. Finally, the pull rope 8 pulls the heavy hammer 4 to prevent the heavy hammer 4 from falling, so that the water outlet height of the drawing nozzle 1 is kept unchanged.
After the drawing shower head 1 hovers, if the user needs to cancel the current water outlet height and return to the initial state, as shown in fig. 11, the user needs to draw a small section of drawing tap again and then loosen the hand. In the process that the user pulls the pull tap again, the pull hose 3 and the heavy hammer 4 move upwards, and at the moment, the rotating wheel 6 only receives the elastic potential energy of the coil spring 7 and rotates in the first direction (namely clockwise), so that the pull rope 8 is recovered; the cylinder 92 originally stops at the stop position 6131, and as the rotating wheel 6 rotates along the first direction, the cylinder 92 rapidly enters the outer groove 612 under the guidance of one side surface of the guiding side surface 6132; after the user loosens his hands, the weight 4 falls down, and the weight 4 received by the pull rope 8 is much greater than the elastic force of the coil spring 7, so that the reel 6 rotates in the second direction to realize paying-off, and at the same time, the cylinder 92 moves in the outer groove 612 in an infinitely reverse direction (i.e. in the first direction), allowing the weight 4 to fall to the lowest point, so that the pull-out nozzle 1 returns to the highest water outlet position.
After the drawing nozzle 1 hovers, if the user feels that the current water outlet height is still higher, and the water outlet height needs to be further reduced, the drawing nozzle 1 needs to be continuously drawn down, as shown in fig. 12, when the user continuously draws down the drawing nozzle 1, the drawing hose 3 and the heavy hammer 4 move upwards, at this time, the rotating wheel 6 only receives the elastic potential energy of the coil spring 7 and rotates along the first direction (namely clockwise direction), so as to recover the pull rope 8; the cylinder 92 originally stops at the stop position 6131, and as the rotating wheel 6 rotates along the first direction, the cylinder 92 rapidly enters the outer groove 612 under the guidance of one side surface of the guiding side surface 6132; as the wheel 6 continues to rotate in the first direction, the cylinder 92 moves in the second direction within the outer groove 612, and when the cylinder 92 reaches the second abrupt change point 6121 of the outer groove 612, the cylinder 92 enters the transition section 614 under the guidance of the outer side surface of the second abrupt change point 6121, and finally reaches the inner groove 611, and moves infinitely counterclockwise within the inner groove 611, thus allowing the drawing nozzle 1 to be continuously drawn to the lowest position.
Referring to fig. 13, in an exemplary embodiment of the utility model, the housing 5 is fixedly connected to the pull hose 3 or the weight 4 connected to the pull hose 3, and one end of the pull rope 8 is higher than the housing 5 and is fixedly connected to the device body (i.e. the faucet body 2) or a preset carrier fixed relative to the device body, wherein the preset carrier may be a sink or other fixing member.
When a user starts to pull the pull sprayer 1, the pull hose 3 moves upwards, the heavy hammer 4 moves upwards, the shell 5 and parts in the shell move upwards together, and the pull rope 8 is recovered downwards into the roller. Other working processes are described above and will not be described here again.
Referring to fig. 14, in another exemplary embodiment of the present utility model, the housing 5 is fixedly connected to a preset carrier fixed to the device body (i.e. the faucet body 2), and the preset carrier may be a sink or other fixing member; one end of the pull rope 8 is connected to the pull hose 3.
When a user starts to pull the pull sprayer 1, the pull hose 3 moves upwards, the heavy hammer 4 moves upwards, one end of the pull rope 8 moves upwards, and the rotating wheel 6 rotates along the first direction to realize paying-off. Other working processes are described above and will not be described here again.
In fig. 9 to 14, the change of the relative position between the runner 6 and the cylinder 92 is not shown, and the drawing hose 3 and the weight 4 are shown in a simple manner, the curved arrow outside the runner 6 shows the rotation direction of the runner 6, the curved arrow inside the runner 6 shows the movement direction of the cylinder 92, and the straight arrow shows the movement direction of the drawing hose 3, the weight 4, the rope 8, etc.
According to the utility model, through the rapid rotation of the rotating wheel 6, the track of the cylinder 92 is limited to enter a specific channel only at a specific crossing due to the radius radian design of the inner groove 611 and the outer groove 612, namely, the cylinder 92 always moves along one side surface (curved surface) of the track groove 61 due to the rapid rotation of the rotating wheel 6, the rotation radius is increased, the inner side surface enables the cylinder 92 to be far away from the center of the rotating wheel 6, and when the rotation radius is reduced, the outer side surface enables the cylinder 92 to be close to the center of the rotating wheel 6, so that the movement track of the moving part 9 in the track groove 61 is limited. Therefore, the bottom surface of the track groove 61 does not need to be provided with a plurality of small steps to limit the movement track of the moving part 9, so that the working failure caused by the abrasion of the small steps is avoided, the track groove can stably work for a long time, and the service life meets the standard requirement. Because the runner 6 is vertically placed, the weight of the sliding block 91 is not too heavy, and materials such as metal are not adopted, otherwise, when the pulling action is slow, the rolling wheel rotates slowly, the sliding block 91 is greatly influenced by gravity and falls freely in advance, and the sliding block enters an unexpected channel.
The hovering positioning mechanism and the water outlet device with the adjustable water outlet height are the same as or can be realized by adopting the prior art.
The above embodiment is only used for further explaining a hover positioning mechanism and a water outlet device with adjustable water outlet height, but the utility model is not limited to the embodiment, and any simple modification, equivalent variation and modification to the above embodiment according to the technical substance of the utility model falls within the protection scope of the technical proposal of the utility model.
