Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a pull-out head. Background Art

[0002] Pull-out faucets are often used on wash basins or kitchen sinks. They typically have two water outlet modes: one for commonly used sparkling water and the other for a more powerful shower. Most pull-out faucets are equipped with a switch. When using the pull-out faucet, the user can pull it out with one hand while holding the object being cleaned with the other, making it easier to clean. Currently, a pull-out faucet has been proposed on the market. In addition to the aforementioned switch, a flow control switch is also provided. This allows the user to control not only the water outlet mode but also the water volume when pulling it out with one hand, meeting a wider range of cleaning scenarios and needs. However, the numerous switches in these pull-out faucets result in a larger overall size. Alternatively, within the same size constraints, the water flow channel may be smaller. Both the excessive size and the low flow rate affect the user experience. Furthermore, existing pull-out faucets do not automatically reset to the sparkling water mode when switching to shower water, making it inconvenient for the next use. Therefore, the present invention provides a pull-out faucet with a compact and interconnected switch structure to address the aforementioned technical issues. Utility Model Content

[0046] As for the compound switch assembly 4, in one embodiment, the compound switch assembly 4 includes a pressing seat 41, a linkage member 42 and a compound key 43. The flow cutting member 3 is movably installed in the installation cavity 12, and one end extends outside the installation cavity 12 to form a pressing end. The pressing seat 41 is movably installed on the periphery of the water outlet body 1 and is close to the pressing end of the flow cutting member 3.

The water inlet 121 is located between the first water outlet 122 and the second water outlet 123, and the plug 32 moves with the telescopic shaft 31 and blocks the second water outlet 123. The water inlet 121 and the first water outlet 122 are connected to form a first water outlet mode, or the plug 32 moves with the telescopic shaft 31 to block the first water outlet 122. The water inlet 121 and the second water outlet 123 are connected to form a second water outlet mode. In addition, preferably, the pressing seat 41 forms the switching action by squeezing the telescopic shaft 31 through the inclined surface, thereby realizing the change of the pressing direction, and the pressing force of the circumference can also drive the axially arranged flow cutting member 3.

[0048] Regarding the above-mentioned inclined surface extrusion structure, in a specific embodiment, the pressing end periphery of the telescopic shaft 31 is provided with a first driving inclined surface 311 and a second driving inclined surface 312, and the pressing seat 41 is provided with a first pressing inclined surface 411 and a second pressing inclined surface 412 facing the pressing end periphery. The first pressing inclined surface 411 and the second driving inclined surface 312 are parallel, and the second pressing inclined surface 412 is parallel to the first driving inclined surface 311. The plug 32 and the telescopic shaft 31 are telescopically mounted, and a travel limit structure is provided in the telescopic direction to prevent the plug 32 and the telescopic shaft 31 from separating from each other. A pre-tightened first spring 33 is provided between the pressing end of the telescopic shaft 31 and the water outlet body 1, and a pre-tightened second spring 34 is provided between the end of the plug 32 and the water outlet body 1.

[0049] The principle of using the flow cutting function of the pull-out head provided in this embodiment is as follows:

[0050] In the initial state, if Figure 7 The second spring 34 pushes and presses the plug 32 onto the second water outlet 123, the water inlet 121 and the first water outlet 122 are connected, the first spring 33 pushes the telescopic shaft 31, and the telescopic shaft 31 and the plug 32 are contracted to the shortest length, and the first pressing inclined surface 411 and the second driving inclined surface 312 are staggered in a direction perpendicular to the axial direction of the telescopic shaft 31, that is, if the pressing seat 41 is pressed at this time, the first pressing inclined surface 411 will squeeze the second driving inclined surface 312, forming a flow cutting action.

[0051] In the water flow state, press the pressing seat 41 through the composite key 43, see Figure 8 , the first pressing inclined surface 411 moves downward and squeezes the second driving inclined surface 312, and drives the telescopic shaft 31 to push the plug 32, the plug 32 compresses the second spring 34 and blocks the first water outlet 122, the water inlet 121 and the second water outlet 123 are connected, at this time, the water outlet mode is switched from the first water outlet mode to the second water outlet mode, then, please refer to Figure 9 The pressing seat 41 is released and reset by the composite key 43, the water pressure in the installation cavity 12 is greater than the elasticity of the second spring 34, and the plug 32 is maintained in a state of blocking the first water outlet 122, and the water pressure in the installation cavity 12 pushes the telescopic shaft 31 to reset and compresses the first spring 33. At this time, the telescopic shaft 31 and the plug 32 are stretched to the longest length, and the second pressing inclined surface 412 and the first driving inclined surface 311 are staggered in a direction perpendicular to the axial direction of the telescopic shaft 31.

[0052] When the pressing seat 41 is pressed again by the composite key 43, refer to Figure 10 and Figure 11The second pressing slope 412 moves downward and compresses the first driving slope 311, driving the telescopic shaft 31 to pull out the plug 32. The plug 32 opens the first water outlet 122 and blocks the second water outlet 123. The second spring 34 and the hydraulic force maintain the blockage of the second water outlet 123. At this time, the second water outlet mode is switched to the first water outlet mode. When the water outlet body 1 stops supplying water, the flow cutter 3 returns to the initial state.

[0053] Regarding the specific structure of the aforementioned travel limit structure, in one embodiment, a telescopic slot 321 is provided at the end of the plug 32 facing the telescopic shaft 31, and the slot 321 has a contraction opening. A piston head 313 is provided at the end of the telescopic shaft 31 facing the plug 32. A telescopic rod 314 is provided at the end of the piston head 313, which is inserted into the telescopic slot 321. A stopper head having a diameter larger than the contraction opening is provided at the end of the telescopic rod 314, forming the travel limit structure between the telescopic slot 321 and the telescopic rod 314. The telescopic shaft 31 reciprocates within the mounting cavity 12 via the piston head 313, and the outer ring of the piston head 313 is provided with a V-shaped opening sealing ring with its opening facing the plug 32.

[0054] In another embodiment, in order to allow the pressing seat 41 to automatically bounce up, a compressed third spring 44 is provided between the pressing seat 41 and the water outlet body 1. The third spring 44 pushes the pressing seat 41 away from the pressing end of the flow cutting member 3, so that the pressing seat 41 can automatically reset after being released. In addition, the water outlet body 1 is provided with limit plates 45 on both sides of the pressing seat 41, and the two limit plates are provided with undercuts 451 that limit the pressing seat 41 from being separated from the installation position. The tops of the two limit plates 45 are provided with parallel and opposite strip openings 452, and the strip openings 452 are parallel to the moving direction of the pressing seat 41, and a constriction is formed at the opening. The top of the pressing seat 41 is provided with an arc groove 413 connected to the two strip openings 452. During installation, the rotating shaft of the composite key 43 is inserted into the two-shaped opening 452 and presses against the arc groove 413. The composite key 43 rotates on the arc groove 413 and in the shaped opening through the rotating shaft, or / and, the composite key 43 moves back and forth in the two-shaped opening 452 through the rotating shaft and presses the pressing seat 41.

[0055] Regarding the optional structure of the linkage member 42 and the water volume adjustment member 2, in one embodiment, the linkage member 42 is telescopically mounted along the axial direction of the water outlet body 1, and a docking port 421 is provided on the periphery of the driving end, parallel to the movable direction of the pressing seat 41. The depth of the docking port 421 is greater than the diameter of the driving head 431. The driving head 431 of the composite key 43 is inserted into the docking port 421. When the driving head 431 rotates around the rotating shaft of the composite key 43, the driving head 431 pushes against the docking port 421 and reciprocates along the docking port 421, thereby driving the linkage member 42 to reciprocate along the axial direction of the water outlet body 1. The water volume adjustment member 2 is cylindrical, telescopically mounted within the water inlet channel 11, and driven by the linkage member 42. The water flow regulating member 2 blocks the water inlet channel 11. A water channel 21 is provided in the center, and regulating holes 22 are provided around the periphery, connected to the water channel 21. The notch of the water channel 21 communicates with the water inlet 121 of the mounting cavity 12 through the water inlet channel 11. The water channel 111 is positioned on a movable track of the regulating hole 22. The water flow regulating member 2 adjusts the amount of water flowing through the water inlet channel 11 by the degree of interlacing between the regulating hole 22 and the water channel 111. The structure is simple and easy to form and assemble.

[0056] To facilitate the rotation of the composite key 43, the composite key 43 is provided with a pressing roller 432 coaxial with its rotating shaft. In addition, to facilitate the adjustment of the water output, the pressing roller 432 rotates in one direction and reaches the limit position, the adjusting hole 22 and the water hole 111 are fully connected, and the water flow is maximized. Alternatively, the pressing roller 432 rotates in the other direction and reaches the limit position, the adjusting hole 22 and the water hole 111 are completely staggered, and the water flow is minimized. As a result, when the pressing roller 432 rolls in one direction, the water output can be reduced, and when it rotates in the other direction, the water output can be increased, thereby avoiding errors in flow regulation.

[0057] Based on the above embodiment, in another embodiment, the pull-out head further comprises a housing 5, one end of which is a mounting opening and the other end is a mounting constriction; the water outlet body 1 is inserted through the mounting opening of the housing 5, the outer periphery of the water inlet end of the water outlet body 1 is provided with threads, extends from the mounting constriction of the housing 5, and is tightened and fixed by a nut 6; the housing 5 is provided with a clearance hole 51 corresponding to the composite switch assembly 4, the pressing roller 432 is connected to the composite key 43 through the clearance hole and exposed from the clearance hole, thereby further confining the water outlet body 1 within the housing 5. Preferably, the pressing roller 432 and the composite key 43 are assembled together by snaps, screws, or adhesive.

[0058] The pull-out head provided by the present invention has both the water outlet mode switching function and the flow regulation function, which provides great convenience for consumers when using water. In addition, by setting the composite switch assembly 4, the two functional modules can be linked at the same time, that is, one switch can control the water outlet mode and regulate the water output. On the one hand, the number of switches set is reduced to form a more compact pull-out head, avoiding the problems of large product size or small water flow channel caused by setting multiple switches, and will not cause the problem of large size of the pull-out head and inconsistent proportion with the faucet, nor will it cause the problem of small water flow.
