[0019] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0020] In the description of the present utility model, unless otherwise specified, "multiple" means two or more than two; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] like Figure 1-5As shown, an annular spray nozzle described in this embodiment includes a base 1, a pressing head 2 and a mist outlet ring 3. The materials of the base 1, the pressing head 2 and the mist outlet ring 3 are all plastic. The base 1 is used to buckle on the spray bottle. The top of the spray bottle is provided with a downward pressure liquid outlet head. One side of the pressing head 2 is connected to the base 1, and there is a gap between the other periphery and the base 1, so that the pressing head 2 can swing up and down. A liquid inlet pipe 4 is arranged on the bottom surface of the pressing head 2, and the liquid inlet pipe 4 is buckled on the downward pressure liquid outlet head. When the pressing head 2 is pressed down, the downward pressure liquid outlet head is pressed, and the liquid in the spray bottle flows out into the liquid inlet pipe 4 through the downward pressure liquid outlet head. The mist outlet ring 3 is vertically arranged on the pressing head 2. On the head 2, an annular flow channel 5 connected with the liquid inlet pipe 4 is arranged in the mist outlet ring 3, and eight axial flow channels 6 are evenly distributed along the circumference on the annular flow channel 5; an adjusting plate 7 is also axially slidably arranged on the mist outlet ring 3, and two valve stems 8 are symmetrically arranged on the adjusting plate 7, and the valve stem 8 is close to the liquid inlet pipe 4. Specifically, there are three axial flow channels 6 that are always connected with the liquid inlet pipe 4 between the two valve stems 8, and a valve head 9 is arranged on the valve stem 8. The valve head 9 is made of rubber, and a socket 10 matched with the valve head 9 is arranged on the mist outlet ring 3. The socket 10 is connected with the annular flow channel 5, and the valve head 9 can extend into the annular flow channel 5 and prevent the liquid from continuing to flow upward.

[0022] The pressing head 2 is provided with a plurality of anti-slip edges 11 to increase the friction between the finger and the pressing head 2, making it easier to press.

[0023] The mist outlet ring 3 comprises an outer ring 12 and an inner ring 13 which are coaxially arranged. The outer ring 12 and the inner ring 13 are provided with annular grooves correspondingly. The two annular grooves together form an annular flow channel 5. The inner ring 13 is also provided with an axial groove. The axial groove and the outer ring 12 together form an axial flow channel 6. The cross section of the axial groove is semicircular.

[0024] The adjusting piece 7 is arc-shaped, and a mounting groove matching with the adjusting piece 7 is provided on the outer ring 12. The outer ring of the adjusting piece 7 does not protrude from the outer ring, so as to keep the overall structure of the mist outlet ring 3 unified; preferably, a transparent plastic cap can be detachably buckled on the base 1, and the transparent plastic cap buckles the pressing head 2 and the mist outlet ring 3 inside, so as to ensure the cleanliness of the pressing head 2 and the mist outlet ring 3;

[0025] like Figure 6 As shown, a blind hole 14 corresponding to the axial groove on the inner ring 13 is provided on the outer ring 12, and the blind hole 14 is close to the front side of the mist outlet ring 3. A silicone diaphragm 15 is provided at the opening of the blind hole 14. In a natural state, the silicone diaphragm 15 penetrates into the axial groove and blocks the axial groove. When the pressurized liquid is sprayed into the axial groove, the silicone diaphragm 15 retracts into the blind hole 14 in the reverse direction, and the liquid is sprayed out of the axial groove normally. This can make the axial groove be immediately blocked when the spraying stops, so as to prevent the liquid in the annular flow channel 5 and the axial flow channel 6 from seeping out of the mist outlet ring 3 and contaminating the pressing head 2 and the mist outlet ring 3.

[0026] The working principle of this embodiment is:

[0027] When an annular spray is required, the adjusting plate 7 slides to the rear side. At this time, pressing the pressing head 2 can realize the discharge of liquid from all axial flow channels 6, and the spray area is large; when a surface spray is required, the adjusting plate 7 slides to the front side, the valve head 9 is inserted into the annular flow channel 5 and blocks the channel for the liquid to continue to flow upward. After the liquid in the liquid inlet pipe 4 enters the annular flow channel 5, it can only be sprayed out through the three upstream axial flow channels 6 to form a surface spray. Of course, the position of the valve stem 8 or the number of axial flow channels 6 can be adjusted as needed during the production process, so that the number of axial flow channels 6 that are always connected to the liquid inlet pipe 4 is reduced to one. At this time, the dual-mode use of annular spray and point spray can be realized; compared with the prior art, the present embodiment can switch between annular spray and point surface spray, which not only meets the use requirements of large-area rapid spraying, but also can obtain better effects when spraying key parts in a targeted manner, and can also save cosmetic materials and reduce daily use costs.

[0028] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific uses.
