DETAILED DESCRIPTION

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention is 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 the present invention and are not intended to limit the present invention.

[0032] See also Figures 1 to 7 A pull-out head includes a water outlet body 1, a switching switch 2 and an adjusting switch 3, wherein:

[0033] The water outlet body 1 is provided with a water inlet channel 11, an installation cavity 12, a first water outlet channel 13, and a second water outlet channel 14. The switching switch 2 is installed in the installation cavity 12. The water inlet channel 11 is connected to the first water outlet channel 13 or the second water outlet channel 14 by the switching action of the switching switch 2. The second water outlet channel 14 extends to the top of the water outlet body 1 and forms a top water outlet 15. The regulating switch 3 is arranged at the top water outlet 15. The top water outlet 15 discharges mist water and columnar water by adjusting the regulating switch 3.

[0034] For the convenience of adjustment, the regulating switch 3 is a rotary switch. On this basis, the regulating switch 3 is further a stepless switch, so that stepless adjustment can be performed from mist water to columnar water, which can meet the different usage needs of consumers.

[0035] Based on the above embodiment, the regulating switch 3 is rotatably mounted on the top of the water outlet body 1 via a threaded connection. This simple structure is not only easy to form but also easy to assemble. Specifically, the outlet end of the second water outlet channel 14 extends out of the water outlet body 1 to form a water outlet column 16. The outer periphery of the water outlet column 16 is provided with an external thread. The regulating switch 3 is provided with a connection groove on the side facing the water outlet body 1. The connection groove has an internal thread and is threadedly connected to the water outlet column 16.

[0036] In one embodiment, a protruding column 17 is provided in the middle of the top water outlet 15, and a swirl structure is provided at the end of the column 17. The regulating switch 3 is cap-mounted, covering the top water outlet 15, and is provided with a water outlet hole 31 corresponding to the extension direction of the column 17. The regulating switch 3 is rotated to adjust the distance between the water outlet hole 31 and the end of the column 17. When the end of the column 17 presses against the inner opening of the water outlet hole 31, water flows through the swirl structure and is sprayed out of the water outlet hole 31 in an atomized state. At this time, the water discharged is a mist with the smallest particle size. When the end of the column 17 is farthest from the inner opening of the water outlet hole 31, the water flows directly through the water outlet hole 31 to form a columnar water outlet. At this time, the water discharged is a columnar water with the largest diameter.

[0037] Specifically, the swirl structure includes a connected swirl groove 171 and a tangential water inlet groove 172. The swirl groove 171 is arranged at the top of the boss 17, and the tangential water inlet groove 172 is arranged around the swirl groove 171. When the swirl groove 171 is against or close to the water outlet of the regulating switch 3, water enters the swirl groove 171 through the tangential water inlet groove 172 and forms rotating water. Therefore, when the rotating water is sprayed out from the water outlet, it is sprayed out in the form of granular water with smaller particle size to form atomized water.

[0038] In addition, the inner opening of the water outlet 31 is expanded, with the larger diameter end facing the protrusion 17, thereby forming a conical opening at the water outlet, which helps increase the water velocity. The outer opening of the water outlet 31 is tapered, with the larger diameter end facing outward, which is conducive to the spraying of water mist.

[0039] In order to be able to discharge finer water, preferably, the diameter of the water outlet 31 is 0.7mm-1.3mm. For example, the diameter of the water outlet 31 used in this embodiment is 1mm, which can discharge a very fine water column to meet the requirements of flushing teeth.

[0040] On the basis of the above embodiment, to enable the pull-out head to have more water outlet functions, the water outlet body 1 is further provided with a second mounting cavity 18 and two water passages. One end of each of the two water passages is connected to the second water outlet channel 14 through the mounting cavity 12, and the other end is provided with two types of water outlet nozzles at the bottom of the water outlet body 1. A flow cut-off switch 19 is installed in the second mounting cavity 18, and the second water outlet channel 14 is connected to the water passage of any water outlet nozzle by switching the flow cut-off switch 19.

[0041] In this embodiment, the switching switch 2 and the flow cut switch 19 are both push switches, and both adopt a telescopic rod switching structure, which is a prior art and will not be described in detail here.

[0042] The drawer head provided by the present invention is provided with an adjustment switch 3 at the top water outlet 15, which can adjust the water outlet state of the top water outlet 15 to form mist-like water outlet or columnar water outlet, thereby enriching the book outlet mode and function of the upward water outlet on the drawer head and meeting the different usage needs of consumers.
