Description

Technical Field

[0001] The utility model relates to the field of bathrooms, in particular to a lifting faucet. Background Art

[0002] A water faucet is a valve used to control the water flow or water stop of a water channel. Existing water faucets are generally one-piece structures with a fixed water outlet height, so there are great limitations in actual use. A lifting faucet has appeared on the market, which can change the water outlet height of the faucet and realize the free rotation of the faucet.

[0003] However, this type of faucet usually includes a body, a water outlet assembly, a sleeve and a lifting pipe. The sleeve is inserted into the channel of the body and fixed to the body; the lifting pipe is inserted into the sleeve and moves along the length direction of the sleeve. The end of the lifting pipe is fixed to the water outlet assembly. In order to avoid abnormal noise when the lifting pipe is lifted, a limiter is set in the channel, and the lifting pipe passes through the limiter. The isolation effect of the limiter prevents the lifting pipe from directly contacting the body and reduces noise. However, with this structure, due to the effect of the limiter, the friction between the two shafts is increased, so that the lifting pipe is not smooth when it is lifted up and down, and there is a sense of jamming.

[0030] The present utility model will be further described below through specific embodiments.

[0031] See Figures 1 to 7, a lifting faucet, including a valve body 10, a water outlet assembly 20, a button assembly 30, etc. The valve body 10 is provided with an axially penetrating channel 11. The water outlet assembly 20 is provided with a communicating channel 21 and a water outlet 22. A part of the water outlet assembly 20 is inserted into the channel 11 and can axially move and circumferentially rotate relative to the valve body 10. By axially lifting the water outlet assembly 20, the height of the water outlet 22 is changed, and by rotating the water outlet assembly 20, the direction of the water outlet 22 is changed. The button assembly 30 is arranged on the valve body 10 and is provided with a sleeve 31 that can move radially. The sleeve 31 is sleeved on the outer periphery of the water outlet assembly 20 and can radially move to hold or release the water outlet assembly 20. When the button assembly 30 releases the water outlet assembly 20, the water outlet assembly 20 can be lifted, and when the button assembly 30 holds the water outlet assembly 20, the water outlet assembly 20 can be held so that the water outlet 22 is positioned at the current height.

[0032] It further includes a rolling component 40. The rolling component 40 is installed in the channel 11 and is provided with a number of rolling balls 41. The number of rolling balls 41 is located on the outer periphery of the water outlet assembly 20 and is in point contact with it to roll when the water outlet assembly 20 axially moves. The arrangement of the rolling balls 41 makes the axial movement of the water outlet assembly 20 smoother.

[0033] Among them, the inner wall of the channel 11 of the valve body 10 is provided with a circumferentially extending first groove 12 and a second groove 13. Both the first groove 12 and the second groove 13 are annular grooves arranged around the inner wall of the channel 11, and the first groove 12 and the second groove 13 are axially distributed along the valve body 10. The button assembly 30 is located in the first groove 12, and the rolling component 40 is located in the second groove 13. In the figure, the first groove 12 is arranged above the second groove 13. In actual application, the first groove 12 can also be arranged below the second groove 13.

[0034] The water outlet assembly 20 includes a rod body 23 and a water outlet part 24. One end of the rod body 23 is inserted into the channel 11 and is in sliding fit with it. The other end of the rod body 23 is connected to and communicates with the water outlet part 24. The communicating channel 21 is formed in the rod body 23 and the water outlet part 24. A waterway hose can be arranged in the communicating channel 21, and the waterway hose also passes through the rod body 23 and is inserted into the channel 11 of the valve body 10 to access the water flow. The water outlet part 24 is also provided with a water outlet 22, and the water outlet 22 communicates with the waterway hose to discharge water.

[0035] Among them, at least one radially extending convex block 25 is arranged on the outer periphery of the end of the rod body 23 inserted into the channel 11. A limiting surface 42 is arranged at one end of the rolling component 40 close to the convex block 25 in the axial direction. The cooperation of the convex block 25 and the limiting surface 42 can be used to limit the distance of the axial upward movement of the water outlet assembly 20, that is, when the water outlet assembly 20 axially moves upward until the convex block 25 abuts against the limiting surface 42, it stops, preventing the rod body 23 from detaching from the channel 11 of the valve body 10.

[0036] Further, the outer diameter of the end of the water outlet part 24 connected to the rod body 23 is greater than the outer diameter of the rod body 23. A abutting surface 14 is provided at the end of the valve body 10 opposite to the water outlet part 24. The abutting surface 14 is provided to limit the maximum distance of the axial downward movement of the water outlet part 24, that is, when the water outlet part 24 axially moves downward and abuts against the abutting surface 14, the movement stops. In addition, the outer diameter of the end of the valve body 10 where the abutting surface 14 is located is set to be equal to the outer diameter of the corresponding end of the water outlet part 24. When the water outlet assembly 20 axially moves until the end of the water outlet part 24 connected to the rod body 23 abuts against the abutting surface 14, the outer periphery at the junction of the water outlet part 24 and the valve body 10 is flush, which is more beautiful.

[0037] The button assembly 30 further includes a button 32 and an elastic member 33. The button 32 is connected to the sleeve 31 and is partially exposed on one side in the radial direction of the valve body 10. By pressing the button 32, the sleeve 31 moves radially to release the water outlet assembly 20. The elastic member 33 is arranged between the inner wall on the other side of the valve body 10 opposite to the button 32 in the radial direction and the sleeve 31. The elastic member 33 is arranged to drive the sleeve 31 to move radially to hold the water outlet assembly 20 tightly.

[0038] Specifically, connection parts 34 are respectively arranged on both sides of the sleeve 31 in the radial direction. The button 32 is connected to one of the connection parts 34, and the elastic member 33 is connected to the other connection part 34, that is, the button 32 and the elastic member 33 are respectively located on both sides of the sleeve 31 in the radial direction, so that the directions of the button 32 and the elastic member 33 driving the sleeve 31 to move radially are opposite. The elastic member 33 is a spring piece or a spring, etc. In the figure, a spring piece is taken as an example. The middle part of the elastic member 33 is fixedly connected to the connection part 34. Elastic arms 35 are further arranged at both ends of the elastic member 33. The elastic arms 35 abut against the inner wall of the valve body 10 opposite to the elastic arms 35. When the button 32 is pressed, the sleeve 31 moves radially, causing the elastic member 33 to be stressed and the elastic arms 35 to deform. When the button 32 is released, the elastic member 33 returns to its original position and drives the sleeve 31 to move radially back to its original position.

[0039] Further, the rod body 23 is a rod body 23 made of a metal material. The button assembly 30 is further provided with a magnetic member 36. The magnetic member 36 is embedded in the inner wall of the sleeve 31 opposite to the rod body 23, near the location of the elastic member 33. The rod body 23 of the water outlet assembly 20 is adsorbed by the magnetic member 36 to hold the water outlet assembly 20 tightly, that is, the suction force of the magnetic member 36 is combined with the elastic force of the elastic member 33 to make the holding force on the rod body 23 of the water outlet assembly 20 stronger. When the sleeve 31 moves radially under the action of the button 32, the magnetic member 36 disengages from the rod body 23 of the water outlet assembly 20, that is, the water outlet assembly 20 is released. The magnetic member 36 is a magnet, and its size is set according to the size of the sleeve 31.

[0040] In practical applications, a soft pad can also be used to replace the magnetic member 36. The soft pad is embedded in the inner wall of the sleeve 31 opposite to the rod body 23. Under the elastic force of the elastic member 33, the soft pad closely adheres to the outer circumference of the rod body 23 to tightly hold the water outlet assembly 20. When the sleeve 31 moves radially under the action of the button 32, the soft pad disengages from the rod body 23 of the water outlet assembly 20, that is, the water outlet assembly 20 is released.

[0041] The rolling assembly 40 includes a mounting seat 43. The mounting seat 43 is axially penetrated and a ring groove 44 is provided on its inner wall. A number of balls 41 are located in the ring groove 44 and are arranged around the outer circumference of the rod body 23 of the water outlet assembly 20. The two ends of the balls 41 in the radial direction of the valve body 10 are in point contact with the inner wall of the ring groove 44 and the outer circumference of the rod body 23 respectively. When the rod body 23 moves axially along the channel 11, each ball 41 rolls. Since the balls 41 are in point contact with the surface of the rod body 23 and are in relative motion, the frictional force between the two is very small, and the movement of the rod body 23 is smoother.

[0042] In addition, a locking member 60 is further included. One end of the locking member 60 is inserted into the valve body 10 and is detachably and fixedly connected to the valve body 10. The end of the locking member 60 inserted into the valve body 10 abuts against the corresponding end face of the mounting seat 43, so as to fix the mounting seat 43 in the valve body 10. The other end of the locking member 60 is located outside the valve body. The valve body 10 is fixed on the table top through the cooperation of the locking member 60 and the locking assembly.

[0043] For the faucet of the present utility model, whether the sleeve 31 holds the rod body 23 tightly or releases the rod body 23, the water outlet assembly 20 can rotate circumferentially relative to the valve body 10. A handle assembly 50 is further provided on the valve body 10. The handle assembly 50 includes a valve core 51, a handle 52, etc. The on-off of the water passage in the valve body 10 is controlled through the handle assembly 50, and then the opening and closing of the water outlet of the water outlet part 24 is controlled. Taking the example that the sleeve 31 is embedded with a magnetic member 36, the lifting working principle of the faucet of the present utility model is as follows:

[0044] When the button 32 is pressed, under the action of an external force, the sleeve 31 moves radially and squeezes the elastic member 33 to deform. The magnetic member 36 disengages from the surface of the rod body 23, and the sleeve 31 has no holding force on the rod body 23, and the rod body 23 is released; when the water outlet assembly 20 is lifted, since the rolling assembly 40 is provided with balls 41, during the axial movement of the rod body 23, the balls 41 will move relatively, and the rod body 23 can move smoothly.

[0045] When the button 32 is released, there is an attraction force between the magnetic member 36 and the outer surface of the rod body 23. The magnetic member 36 adsorbs the rod body 23, and the elastic force of the elastic member 33 is also used to increase the extrusion force between the surface of the magnetic member 36 and the rod body 23, so that the sleeve 31 firmly holds the rod body 23, and the elastic force and the attraction force also overcome the gravity of the water outlet assembly 20, so that the water outlet assembly 20 will not fall freely and is positioned at the required height.

[0046] For the faucet of the present utility model, when the button 32 is pressed, the water outlet assembly 20 can axially move freely and smoothly, and when the button 32 is released, the water outlet assembly 20 remains stationary relative to the valve body 10, with simple operation.

[0047] The terms "first", "second", etc. appearing in the present utility model are only for convenient description to distinguish different components with the same name, and do not indicate the sequence or primary-secondary relationship.

[0048] In the description of the present utility model, the orientation or positional relationship indicated by "up", "down", "left", "right", "front" and "back" is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present utility model, rather than indicating or implying that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the protection scope of the present utility model.

[0049] In addition, in the description of the present application, unless otherwise specified, "a plurality of" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0050] The above is only the specific implementation manner of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantive modification made to the present utility model using this concept shall fall within the scope of infringement of the protection scope of the present utility model.
