Technical Field

[0001] This utility model relates to a compact pull-out head. Background Technology

[0002] In the prior art, such as the applicant's earlier Chinese utility model patent application, patent number CN212899881U, entitled "A Miniaturized Pull-Out Head," a miniaturized pull-out head is designed. It employs a sliding structure of a valve core and a switching shaft, combined with a reset elastic element and a linkage block. The valve core is driven by a button to switch between different positions, and automatically resets to its initial state under water pressure, thus achieving a memory function for the water outlet path. However, this pull-out head can only perform the function of switching water paths and cannot adjust the water flow rate.

[0003] In view of this, how to provide a compact pull-out head that can switch water channels and adjust flow rate, and is easy to operate, is a technical problem to be solved in this field. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to propose a pull-out head that has both water path switching function and water flow rate adjustment function, which has a simple and compact structure and is easy to operate.

[0010] A composite switch is rotatably mounted on the pressing base, and pressing the composite switch causes the pressing base to slide.

[0011] A flow regulating vane is rotatably disposed within the main body and cooperates with the flow regulating port. By rotating the composite switch, the flow regulating vane is driven to rotate, thereby controlling the opening size of the flow regulating port.

[0013] In a preferred embodiment, the device further includes a slider and a rack. A gear that meshes with the rack is fixedly connected to the side of the flow regulating plate facing away from the flow regulating port. The rack is also provided with a convex shaft. The slider is provided with a first linkage groove and a second linkage groove. The composite switch is provided with a swing arm. The swing arm drives the slider through the first linkage groove. The slider drives the rack to slide in a direction perpendicular to the slider through the cooperation of the convex shaft and the second linkage groove.

[0014] In a preferred embodiment, the swing arm is capable of rotating and sliding within the first linkage groove.

[0015] In a preferred embodiment, the second linkage groove is an elongated groove and is inclined along the sliding direction of the slider.

[0016] In a preferred embodiment, the flow regulating plate is provided with a blocking part, and the blocking area of ​​the blocking part on the flow regulating port can be adjusted by rotating the flow regulating plate.

[0017] In a preferred embodiment, the flow regulating plate is located upstream of the water path switching component in the water flow direction.

[0018] In a preferred embodiment, the water path switching assembly includes a switching shaft that slides between a first position and a second position along the axial direction of the body.

The pressing seat is provided with a first inclined block, and the switching shaft is provided with a second inclined block. The first inclined block and the second inclined block are respectively provided with transmission inclined surfaces on both sides of the sliding direction of the switching shaft.

[0019] In a preferred embodiment, a reset elastic element is further included for driving the press seat to reset.

Furthermore, the composite switch is rotatably mounted on a press base. Pressing the composite switch causes the press base to slide, which in turn triggers a water path switching component to switch water paths, thus achieving water path switching. Therefore, the pull-out head of this invention possesses both water path switching and water flow regulation functions. In addition, because the flow control is achieved using a rotatable flow regulating plate within the main body, the flow regulation structure is simple, occupying little internal space, resulting in a very compact and small overall structure for the pull-out head.

[0047] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model 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 only used to explain this utility model and are not intended to limit this utility model.

[0048] Please see Figures 1 to 10 A preferred embodiment of the present invention provides a compact pull-out head, comprising a body 10, a water path switching component 20, a pressing base 30, a composite switch 40, a flow regulating plate 50, and other components, wherein:

[0049] The main body 10 has a water inlet channel 11 and several water outlet channels 12, and a flow regulating port 111 is formed on the water inlet channel 11;

[0050] The water path switching component 20 is movably installed inside the main body 10 and is used to control the water inlet channel 11 to switch between being connected to each water outlet channel 12. The water path switching component 20 can adopt an existing known structure, as long as it can switch between being connected to each water outlet channel 12.

[0051] The pressing seat 30 is slidably disposed inside the main body 10 and is linked to the water circuit switching component 20 to perform a switching action;

[0052] The composite switch 40 is rotatably mounted on the pressing base 30, and pressing the composite switch 40 causes the pressing base 30 to slide.

[0053] The flow regulating plate 50 is rotatably disposed inside the body 10 and cooperates with the flow regulating port 111. By rotating the compound switch 40, the flow regulating plate 50 is driven to rotate, thereby controlling the opening size of the flow regulating port 111.

[0054] A flow regulating port 111 is formed on the water inlet channel 11 of the main body 10, and a flow regulating plate 50 is set so that the flow regulating plate 50 is rotatably set inside the main body 10 and cooperates with the flow regulating port 111. By rotating the compound switch 40, the flow regulating plate 50 is driven to rotate, thereby controlling the opening size of the flow regulating port 111 and realizing the flow regulation function of water flow.

[0055] The composite switch 40 is rotatably mounted on the pressing base 30. Pressing the composite switch 40 causes the pressing base 30 to slide. When the pressing base 30 slides, it can link the water circuit switching component 20 to perform water circuit switching action, thereby realizing the water circuit switching function. Therefore, the pull-out head with the above solution has both water circuit switching function and water flow rate adjustment function.

[0056] Because flow control is achieved by using a flow regulating plate 50 that rotates within the main body 10, the flow regulation structure is simple and occupies little internal space, resulting in a very compact and small overall structure for the pull-out head. Furthermore, since the composite switch 40 switches when pressed and regulates water flow when rotated, both water path switching and flow rate adjustment can be performed on a single switch, making operation very convenient and eliminating the need for two separate switches, resulting in a cleaner appearance.

[0057] Specifically, in this embodiment, an inlet cavity 13 is formed within the water inlet channel 11. The flow regulating plate 50 is rotatably located within the inlet cavity 13. A flow regulating port 111 is provided on the bottom wall of the inlet cavity 13. The side of the flow regulating plate 50 near the flow regulating port 111 is in contact with the bottom wall of the inlet cavity 13. The rotation axis of the flow regulating plate 50 is parallel to the axis of the main body 10. This design makes the flow regulating structure very simple and occupies very little space within the main body 10.

[0058] To enable the composite switch 40 to both slide and drive the press base 30, and to rotate and drive the flow regulating plate 50, this embodiment also includes a slider 60 and a rack 70. A gear 80, meshing with the rack 70, is fixedly connected to the side of the flow regulating plate 50 facing away from the flow regulating port 111. The rack 70 also has a convex shaft 71, and the slider 60 has a first linkage groove 61 and a second linkage groove 62. The composite switch 40 has a swing arm 41, which drives the slider 60 through the first linkage groove 61. The slider 60, through the engagement of the convex shaft 71 and the second linkage groove 62, drives the rack 70 to slide in a direction perpendicular to the slider 60. This arrangement of the slider 60, rack 70, and gear 80 converts the rotation of the composite switch 40 into the rotation of the flow regulating plate 50, resulting in a simple and compact structure with reliable and labor-saving transmission.

[0059] In this embodiment, the swing arm 41 can rotate and slide within the first linkage groove 61, so that the swing arm 41 can smoothly drive the slider 60 to slide when it swings.

[0060] In this embodiment, the second linkage groove 62 is an elongated groove and is inclined along the sliding direction of the slider 60. This design is ingenious and can convert the sliding direction of the slider 60 into the sliding direction of the rack 70. Furthermore, the sliding direction of the rack 70 is perpendicular to the sliding direction of the slider 60, thereby making the transmission structure compact, simple, reliable, and smooth.

[0061] In this embodiment, the flow regulating plate 50 is provided with a blocking part 51. The blocking area of ​​the blocking part 51 on the flow regulating port 111 is adjusted by rotating the flow regulating plate 50. It is understood that when the blocking area of ​​the blocking part 51 on the flow regulating port 111 is large, the flow regulating port 111 opens less, such as... Figure 9 As shown; when the blocking area of ​​the blocking part 51 on the flow regulating port 111 is small, the flow regulating port 111 opens larger, such as Figure 10 As shown.

[0062] In this embodiment, the flow regulating plate 50 is located upstream of the water path switching component 20 in the water flow direction.

[0063] The specific structure and working principle of the water path switching component 20 in this embodiment are largely the same as the technical solution of the applicant's prior patent application CN212899881U, which is roughly as follows: The water path switching component 20 includes a switching shaft 21 that slides along the axial direction of the body 10 between a first position and a second position. The water outlet channel 12 includes a first water outlet channel and a second water outlet channel. The first water outlet channel is connected to the lower water outlet 100 for downward water discharge, and the second water outlet channel is connected to the upper water outlet 110 for upward water discharge. In the first position, the switching shaft 21 controls the water inlet channel 11 to be connected to the first water outlet channel 12. In the second position, the switching shaft 21 controls the water inlet channel 11 to be connected to the second water outlet channel 12. Specifically, the pressing seat 30 is provided with a first inclined block 31, and the switching shaft 21 is provided with a second inclined block 211. The first inclined block 31 and the second inclined block 211 are respectively provided with transmission inclined surfaces on both sides of the sliding direction of the switching shaft 21. The specific structure and working principle of the waterway switching component 20, which are not otherwise described, are referred to in the applicant's prior patent application CN212899881U, and will not be described in detail here.

[0064] It is understandable that the water path switching component 20 of this utility model can also adopt other existing water path switching structures, such as a ballpoint pen press structure.

[0065] In this embodiment, a reset elastic element 32 for driving the pressing seat 30 to reset is also included. The reset elastic element 32 is specifically a compression spring.

[0066] In this embodiment, a housing 90 is also included, with the main body 10 located inside the housing 90. The composite switch 40 has an arc-shaped operating part that protrudes from the housing 90. The arc-shaped operating part facilitates the rotation of the composite switch 40, thereby improving the operating feel.

[0067] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
