Description

Technical Field

[0001] This invention relates to the field of kitchen and bathroom technology, and in particular to a pull-out drawer equipped with a composite switch. Background Technology

[0002] Pull-out taps, as adapters installed at the tap's outlet, can be pulled out for use, greatly facilitating rinsing operations in different areas such as sinks and washbasins, significantly improving flexibility and cleaning effectiveness. To enrich the functional experience, pull-out taps on the market typically need to have multiple functions such as water flow mode switching (e.g., shower water, aerated water) or flow rate adjustment, which relies on internal water path switching and control mechanisms. However, due to the limited overall size of pull-out taps, their internal space is very compact, making it difficult to accommodate multiple independent function switches. Therefore, the industry has proposed the design concept of composite switches, aiming to achieve multiple functions through a single control element. However, existing composite switch solutions still have significant drawbacks, mainly manifested in poor layout, large size, and narrow water passages, further exacerbating the difficulty of miniaturizing pull-out tap designs and hindering further improvements in product experience. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this invention proposes a composite switch-type pull-out head with a more reasonable layout.

[0004] A pull-out head equipped with a composite switch includes a water outlet body, a flow regulating component, a switching component, and a composite switch, wherein, The water outlet body includes a first water passage cavity, a connecting channel, and a second water passage cavity connected in sequence. The first water passage cavity is connected to the water inlet end of the water outlet body, and the second water passage cavity is connected to the water outlet head of the water outlet body. The water outlet head is provided with at least two water outlet channels.

[0005] The flow regulating component adopts a shaft structure and is arranged in the first water passage cavity along the axial direction of the water outlet body, which can avoid forming a flow regulating structure with a large diameter and occupying a large installation space.

[0006] The switching component adopts a shaft structure and is arranged in the second water passage cavity along the axial direction of the water outlet body, which can avoid forming a switching structure with a large diameter and occupying a large installation space.

[0007] The composite switch is disposed on the outer periphery of the connecting channel and located in the groove between the first and second water passage chambers, making full use of the empty space in this position. The composite switch adopts a press-and-roll combination installation structure. The composite switch is linked to the flow regulating component, and the rolling action drives the flow regulating component to control the water supply from the first water passage chamber to the connecting channel. The composite switch is also linked to the switching component, and the pressing action drives the switching component to switch the connection between any water outlet channel and the second water passage chamber.

[0008] The pull-out head provided by this invention is equipped with a composite switch, which integrates the flow regulation function and the switching function into the same switch component, avoiding the need for too many switch components. In addition, the groove between the first and second water passage chambers is fully utilized to form the installation position of the composite switch, avoiding space waste and making the installation more compact. Furthermore, the flow regulation component and the switching component not only adopt a shaft structure, which can reduce the diameter of the pull-out head, but also distribute the components on both sides of the composite switch, which can prevent the functional components from excessively compressing the water passage space when assembled together, thereby avoiding affecting the water output.

[0009] Preferably, the flow regulating component includes a flow regulating shaft, which is rotatably installed in the first water passage chamber. The rotation of the composite switch drives the flow regulating shaft to rotate through a gear and rack structure, adjusting the water supply from the first water passage chamber to the connected channel, thereby achieving the function of water output regulation. The switching component includes a switching shaft, which is telescopically installed in the second water passage chamber. The pressing action of the composite switch drives the switching shaft to telescopically move through an inclined structure, switching the water output from any of the water outlet channels, thereby achieving the function of switching water output modes.

[0010] Preferably, the composite switch includes a swing element, a lifting seat, and a return spring. The water outlet body has an installation position on the periphery of the connecting channel. The lifting seat is installed vertically at the installation position. The return spring is compressed between the lifting seat and the installation position, providing a restoring force to the lifting seat away from the installation position. The installation position has a pair of mounting ears on both sides of the lifting seat. The ends of the mounting ears have U-shaped mounting holes, with the openings of the mounting holes forming a narrowing. The two ends of the swing element's rotating shaft are respectively engaged in the mounting holes of the two mounting ears. The swing element has the freedom of swinging and vertical movement via the rotating shaft. When the swing element moves downwards, it presses against the lifting seat, thereby driving the flow regulating component and the switching component respectively.

[0011] Preferably, the first water passage chamber is divided into an inlet chamber and an outlet chamber. A flow regulating channel is provided between the inlet chamber and the water passage chamber. The flow regulating channel is located in the inlet chamber and its opening communicates with the outlet chamber. The periphery of the flow regulating channel has a flow regulating port communicating with the inlet chamber. The flow regulating shaft is rotatably installed in the flow regulating channel and, by rotating, blocks the opening degree of the flow regulating port, thereby adjusting the water supply from the inlet chamber to the outlet chamber and the communicating channel.

[0012] Preferably, the periphery of the flow regulating shaft is provided with a water passage groove. One end of the water passage groove is aligned with or offset from the flow regulating port by the rotation of the flow regulating shaft, and the other end extends into the water outlet cavity. When the water passage groove is offset from or intersected with the flow regulating port, the periphery of the flow regulating shaft completely or partially blocks the flow regulating port, thereby forming a flow regulating function with no limit to the water pause function.

[0013] Preferably, the communication holes between the first water passage chamber and the inlet end of the water outlet body are distributed on the outer periphery of the flow regulating channel, thereby allowing for a larger water inflow. The presence of two sets of water passage troughs and flow regulating ports further increases the water outflow. Additionally, V-shaped sealing rings are fitted at both ends of the flow regulating shaft, with the openings of the V-shaped sealing rings facing the center of the flow regulating shaft, preventing leakage at the installation point of the flow regulating assembly.

[0014] Preferably, the composite switch further includes a gear and a linkage. The gear is sleeved on the end of the flow regulating shaft extending from the first water passage cavity. The linkage is slidably installed on the periphery of the water outlet body and located between the composite switch and the first water passage cavity. The sliding direction of the linkage is perpendicular to the axial direction of the water outlet body, and the linkage is assembled with the water outlet body through an overlock structure parallel to the sliding direction to prevent the linkage from disengaging from the sliding installation position. The linkage has a rack and a linkage port. The rack meshes with the gear and is parallel to the sliding direction of the linkage, while the linkage port is perpendicular to the sliding direction of the linkage. The rotating shaft of the oscillating member extends into the linkage port and has an oscillating head. The oscillating head oscillates by rotating the shaft, driving the linkage port and the linkage to slide back and forth.

[0015] Preferably, the water outlet head of the water outlet body includes a first water outlet channel and a second water outlet channel. The periphery of the second water passage cavity is provided with a first water outlet and a water inlet, which are respectively connected to the first water outlet channel and the connecting channel. The end of the second water passage cavity away from the composite switch is provided with a second water outlet, which is connected to the second water outlet channel. The water inlet is located between the first water outlet and the second water outlet and is annular. The switching shaft is inserted into the second water passage cavity from the end near the composite switch, and a plug is provided at the end. The plug seals both sides of the water inlet by the extension and retraction movement of the switching shaft, isolating the water inlet from the first water outlet or the second water outlet, thereby forming a flow cutting effect.

[0016] Preferably, the plug has a receiving groove with an elastically constricted opening. The end of the switching shaft has a ball head that inserts into the receiving groove. The switching shaft and the plug form a telescopic member through the receiving groove and the ball head. The switching assembly also includes a first spring and a second spring. The first spring is compressed and disposed between the switching shaft and the water outlet body, providing a thrust for the switching shaft to further insert into the second water passage cavity. The second spring is compressed and disposed between the water outlet body and the plug, providing a thrust for the plug to move toward the switching shaft. The periphery of the switching shaft has a sealing seat and a driving part. The sealing seat is slidably disposed in the mounting port of the second water passage cavity facing the composite switch, and forms a seal with the inner wall of the mounting port through a sealing ring. The lifting seat has a pressing part on the side away from the swinging part. The pressing part is opposite to the driving part, and a first set of inclined surfaces and a second set of inclined surfaces are provided between the pressing part and the driving part to cooperate with each other.

[0017] When the water supply is stopped, the drive unit moves between the pressing part and the second water passage chamber under the push of the first spring. The first set of inclined surfaces are opposite each other, and the second set of inclined surfaces are staggered. The plug overcomes the elastic force of the second spring under the push of the switching shaft and blocks the second water outlet.

[0018] When the pull-out head is in the first water-passing state, water enters the second water passage chamber. The thrust of the second spring is less than the water force on the plug. The plug remains in the state of blocking the second water outlet. Water exits from the first water outlet channel. The drive unit moves between the first water passage chamber and the pressing part under the push of the second spring and the water force, overcoming the thrust of the first spring. The second set of inclined surfaces are opposite each other, and the first set of inclined surfaces are staggered.

[0019] In the first switching state, the oscillating member presses the lifting seat, the pressing part moves downward and pushes the driving part and switching shaft through the second set of inclined surfaces. The switching shaft moves towards the first water passage cavity, causing the plug to open the second water outlet and block the first water outlet, allowing water to flow out of the second water outlet channel. At this time, the sealing seat is separated from the water inlet and is not subject to water force, while the plug is maintained by water force to seal the first water outlet. As the lifting seat resets, the pressing part releases the driving part and switching shaft. The driving part moves between the pressing part and the second water passage cavity under the push of the first spring. The first set of inclined surfaces are opposite each other, and the second set of inclined surfaces are offset, while the plug remains in the state of blocking the first water outlet under the action of water force.

[0020] In the second switching state, the oscillating member presses the lifting seat, the pressing part moves downward and pushes the driving part and switching shaft through the first set of inclined surfaces. The switching shaft moves towards the second water passage cavity, driving the plug to open the first water outlet and block the second water outlet, allowing water to flow from the first water outlet channel. At this time, the sealing seat is connected to the water inlet and is pushed by water force again, while the plug is kept sealed at the bottom of the second water outlet by water force. As the lifting seat resets, the pressing part releases the driving part and switching shaft. Under the push of water force, the driving part overcomes the thrust of the first spring and moves between the first water passage cavity and the pressing part. The second set of inclined surfaces are opposite each other, while the first set of inclined surfaces are offset. The plug is kept sealed at the second water outlet by water force, facilitating the next switching.

[0021] Preferably, the end of the switching shaft facing the first water passage cavity is provided with a groove to accommodate the first spring, and the second spring is disposed in the receiving groove of the plug. The composite switch also includes a roller, which is arc-shaped and mounted on the swing member and coaxial with the swing member, providing an operating position for the user to drive the swing member.

[0022] As can be seen from the above description of the present invention, the present invention has the following beneficial effects: The pull-out head provided by this invention is equipped with a composite switch, which can integrate the current regulation function and the switching function into the same switch, avoiding the need to set too many switches. The present invention makes full use of the groove between the first water passage cavity and the second water passage cavity to form the installation position of the composite switch, avoiding space waste and making the installation more compact; The flow regulating component and switching component provided by the present invention not only adopt a shaft structure, which can reduce the diameter of the pull-out head, but also distribute the components on both sides of the composite switch, which can avoid excessive compression of the water channel space due to the assembly of functional components together, thereby avoiding the impact on the water output.

Detailed Implementation

[0025] To make the technical problems, technical solutions, and beneficial effects of this invention clearer and more understandable, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0026] Please see Figures 1 to 18 A pull-out head equipped with a composite switch 4 includes a water outlet body 1, a flow regulating component 2, a switching component 3, and a composite switch 4, wherein, The water outlet body 1 includes a first water passage chamber 11, a connecting channel 12, and a second water passage chamber 13 connected in sequence. The first water passage chamber 11 is connected to the water inlet end of the water outlet body 1, and the second water passage chamber 13 is connected to the water outlet head of the water outlet body 1. The water outlet head is provided with at least two water outlet channels.

[0027] The flow regulating component 2 adopts a shaft structure and is arranged along the axial direction of the water outlet body 1 within the first water passage cavity 11, which avoids the formation of a flow regulating structure with a large diameter and occupying a large installation space. The switching component 3 adopts a shaft structure and is arranged along the axial direction of the water outlet body 1 within the second water passage cavity 13, which avoids the formation of a switching structure with a large diameter and occupying a large installation space.

[0028] The composite switch 4 is disposed on the outer periphery of the connecting channel 12 and located in the groove between the first water passage cavity 11 and the second water passage cavity 13, making full use of the empty space in this position. The composite switch 4 adopts a press-and-roll combination installation structure. The composite switch 4 is linked to the flow regulating component 2, and the rolling action drives the flow regulating component 2 to control the water supply of the first water passage cavity 11 to the connecting channel 12. The composite switch 4 is linked to the switching component 3, and the pressing action drives the switching component 3 to switch any water outlet channel to connect with the second water passage cavity 13.

[0029] In one embodiment, the flow regulating component 2 includes a flow regulating shaft 21, which is rotatably installed in the first water passage chamber 11. The rotation of the composite switch 4 drives the flow regulating shaft 21 to rotate through a gear 44 and rack 451 structure, thereby adjusting the water supply from the first water passage chamber 11 to the connecting channel 12 and realizing the function of water output regulation. The switching component 3 includes a switching shaft 31, which is telescopically installed in the second water passage chamber 13. The pressing action of the composite switch 4 drives the switching shaft 31 to move telescopically through an inclined structure, switching the water output from any of the water outlet channels and realizing the function of switching water output modes.

[0030] Preferably, the composite switch 4 includes a swing element 41, a lifting seat 42, and a return spring 43. The water outlet body 1 has an installation position 14 on the periphery of the connecting channel 12. The lifting seat 42 is installed vertically at the installation position 14. The return spring 43 is compressed between the lifting seat 42 and the installation position 14, providing a restoring force to the lifting seat 42 away from the installation position 14. The installation position 14 has a pair of mounting ears 15 on both sides of the lifting seat 42. The ends of the mounting ears 15 have U-shaped mounting holes, with the openings of the mounting holes forming a narrowing. The two ends of the rotating shaft of the swing element 41 are respectively inserted into the mounting holes of the two mounting ears 15. The swing element 41 has the freedom of swinging and vertical movement through the rotating shaft. When the swing element 41 moves downwards, it presses against the lifting seat 42, thereby driving the flow regulating component 2 and the switching component 3 respectively.

[0031] Regarding the flow regulation function, based on the above embodiment, the first water passage chamber 11 is divided into an inlet chamber 111 and an outlet chamber 112. A flow regulation channel 113 is provided between the inlet chamber 111 and the water passage chamber. The flow regulation channel 113 is located in the inlet chamber 111 and its opening connects to the outlet chamber 112. The periphery of the flow regulation channel 113 is provided with a flow regulation port 1131 connecting to the inlet chamber 111. The flow regulation shaft 21 is rotatably installed in the flow regulation channel 113 and, by rotating, blocks the opening degree of the flow regulation port 1131, thereby adjusting the water supply from the inlet chamber 111 to the outlet chamber 112 and the connecting channel 12. Preferably, the periphery of the flow regulating shaft 21 is provided with a water passage groove 211. One end of the water passage groove 211 is aligned with or offset from the flow regulating port 1131 by the rotation of the flow regulating shaft 21, and the other end extends into the water outlet cavity 112. When the water passage groove 211 is offset from or intersected with the flow regulating port 1131, the periphery of the flow regulating shaft 21 completely or partially blocks the flow regulating port 1131, thereby forming a flow regulating function with no limit to the water interruption function.

[0032] Furthermore, the communication holes between the first water passage cavity 11 and the water inlet end of the water outlet body 1 are distributed on the outer periphery of the flow regulating channel 113, thereby allowing for a larger water inflow. The water passage trough 211 and the flow regulating port 1131 are in two sets, which can increase the water outflow. In addition, both ends of the flow regulating shaft 21 are fitted with V-shaped sealing rings, with the openings of the V-shaped sealing rings facing the center of the flow regulating shaft 21, which can prevent water leakage at the installation point of the flow regulating assembly 2.

[0033] Based on the above embodiment, the composite switch 4 further includes a gear 44 and a linkage 45. The gear 44 is sleeved on the end of the flow regulating shaft 21 extending from the first water passage cavity 11. The linkage 45 is slidably installed on the periphery of the water outlet body 1 and located between the composite switch 4 and the first water passage cavity 11. The sliding direction of the linkage 45 is perpendicular to the axial direction of the water outlet body 1, and the linkage 45 and the water outlet body 1 are assembled together by an overlock structure parallel to the sliding direction to prevent the linkage 45 from disengaging from the sliding installation position 14. The linkage 45 is provided with a rack 451 and a linkage port 452. The rack 451 meshes with the gear 44 and is parallel to the sliding direction of the linkage 45. The linkage port 452 is perpendicular to the sliding direction of the linkage 45 and is elongated. The pivot of the swing member 41 extends into the linkage port 452 and is equipped with a swing head. The swing head swings by rotating the pivot, causing the linkage port 452 and the linkage member 45 to slide back and forth, thereby driving the flow regulating shaft 21 to rotate. Since the linkage port 452 is elongated and perpendicular to the sliding direction of the linkage member 45, the swing head is allowed to move up and down within the linkage port 452. Therefore, even if the swing member 41 is in a pressed state, the linkage member 45 can still slide by swinging the swing member 41.

[0034] Regarding the flow-cutting function, based on the above embodiment, the water outlet head of the water outlet body 1 includes a first water outlet channel 16 and a second water outlet channel 17. The periphery of the second water passage cavity 13 is provided with a first water outlet 131 and a water inlet 132, which are respectively connected to the first water outlet channel 16 and the connecting channel 12. The end of the second water passage cavity 13 away from the composite switch 4 is provided with a second water outlet 133, which is connected to the second water outlet channel 17. The water inlet 132 is located between the first water outlet 131 and the second water outlet 133 and is annular. The switching shaft 31 is inserted from the end of the second water passage cavity 13 near the composite switch 4, and a plug 32 is provided at the end. The plug 32 blocks both sides of the water inlet 132 by the extension and retraction of the switching shaft 31, isolating the water inlet 132 from the first water outlet 131 or the second water outlet 133, thereby forming a flow-cutting effect.

[0035] Furthermore, the plug 32 is provided with a receiving groove 321, the opening of which is elastically constricted. The end of the switching shaft 31 is provided with a ball head 311, which is inserted into the receiving groove 321. The switching shaft 31 and the plug 32 form a telescopic member through the receiving groove 321 and the ball head 311. The switching assembly 3 also includes a first spring 33 and a second spring 34. The first spring 33 is compressed and disposed between the switching shaft 31 and the water outlet body 1, providing a thrust for the switching shaft 31 to further insert into the second water passage cavity 13. The second spring 34 is compressed and disposed between the water outlet body 1 and the plug 32, providing a thrust for the plug 32 to move toward the switching shaft 31. The periphery of the switching shaft 31 is provided with a sealing seat 312 and a driving part 313. The sealing seat 312 is slidably disposed in the mounting port of the second water passage cavity 13 facing the composite switch 4, and is sealed with the inner wall of the mounting port by a sealing ring. The lifting seat 42 is provided with a pressing part 421 on the side away from the swing member 41. The pressing part 421 is opposite to the driving part 313, and a first set of inclined surfaces 5 and a second set of inclined surfaces 6 are provided between the pressing part 421 and the driving part 313 to cooperate with each other.

[0036] Regarding the switching function of the pull-out head: Please see Figure 9 When the water supply is stopped, the drive unit 313 moves between the pressing unit 421 and the second water passage chamber 13 under the push of the first spring 33. The first set of inclined surfaces 5 are opposite each other, the second set of inclined surfaces 6 are staggered, and the plug 32 overcomes the elastic force of the second spring 34 under the push of the switching shaft 31 and blocks the second water outlet 133.

[0037] Please see Figure 10 In the first water-passing state, water enters the second water passage 13 of the pull-out head, the thrust of the second spring 34 is less than the water force on the plug 32, the plug 32 maintains the state of blocking the second water outlet 133, water exits from the first water outlet channel 16, and water from the shower head is discharged. The drive part 313 moves between the first water passage 11 and the pressing part 421 under the push of the water force, overcoming the thrust of the first spring 33. The second set of inclined surfaces 6 are opposite, and the first set of inclined surfaces 5 are staggered.

[0038] Please see Figure 11In the first switching state, the oscillating member 41 presses down on the lifting seat 42. The pressing part 421 moves downward and pushes the driving part 313 and the switching shaft 31 through the second set of inclined surfaces 6. The switching shaft 31 moves towards the first water passage 11, driving the plug 32 to open the second water outlet and block the first water outlet. Water flows out of the second water outlet channel 17, producing aerated water. At this time, the sealing seat 312 is separated from the water inlet 132 and is not subject to water force, while the plug 32 is held in place by water force to seal the first water outlet. Please refer to [link / reference]. Figure 12 As the lifting seat 42 resets, the pressing part 421 releases the driving part 313 and the switching shaft 31. The driving part 313 moves between the pressing part 421 and the second water passage cavity 13 under the push of the first spring 33. The first set of inclined surfaces 5 are opposite to each other, and the second set of inclined surfaces 6 are staggered. The plug 32 maintains the state of blocking the first water outlet 131 under the action of water force.

[0039] Please see Figure 13 In the second switching state, the oscillating member 41 presses down on the lifting seat 42. The pressing part 421 moves downward and pushes the driving part 313 and the switching shaft 31 through the first set of inclined surfaces 5. The switching shaft 31 moves towards the second water passage 13, driving the plug 32 to open the first water outlet and block the second water outlet. Water flows out of the first water outlet channel 16, spraying water from the shower. At this time, the sealing seat 312 is connected to the water inlet 132 and is pushed by water force again, while the plug 32 is kept sealed at the bottom of the second water outlet by water force. Please refer to [link / reference]. Figure 14 As the lifting seat 42 resets, the pressing part 421 releases the driving part 313 and the switching shaft 31. Under the push of the water force, the driving part 313 overcomes the thrust of the first spring 33 and moves between the first water passage cavity 11 and the pressing part 421. The second set of inclined surfaces 6 are opposite to each other, and the first set of inclined surfaces 5 are staggered. Under the action of water force, the plug 32 maintains the state of blocking the second water outlet 133.

[0040] Regarding the flow adjustment function of the aforementioned pull-out head: Please see Figures 15 to 18 When water is flowing, the oscillating member 41 is pushed and driven by the gear 44 and rack 451 structure to drive the flow regulating shaft 21. When the alignment degree between the water passage 211 of the flow regulating shaft 21 and the flow regulating port 1131 is different, the pull head outputs different amounts of water.

[0041] Based on the above embodiments, the end of the switching shaft 31 facing the first water passage cavity 11 is provided with a groove to accommodate the first spring 33, and the second spring 34 is disposed in the receiving groove 321 of the plug 32. The composite switch 4 also includes a roller 46, which is arc-shaped and mounted on the swing member 41 and coaxial with the swing member 41, providing an operating position for the user to drive the swing member 41. The pull-out head provided by the present invention is equipped with a composite switch 4, which can integrate the flow regulation function and the switching function into the same switch, avoiding the need for too many switches. In addition, the groove between the first water passage cavity 11 and the second water passage cavity 13 is fully utilized to form the installation position 14 of the composite switch 4, avoiding space waste and making the installation more compact. Furthermore, the flow regulation component 2 and the switching component 3 not only adopt a shaft structure, which can reduce the diameter of the pull-out head, but also distribute the components on both sides of the composite switch 4, which can avoid excessive compression of the water passage space when the functional components are assembled together, thereby avoiding affecting the water output.
