[0025] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example 1

[0027] Reference Figures 1 to 6 This embodiment provides an adjustable spray nozzle, including a spray mechanism 200. The spray mechanism 200 includes a valve seat 201, a valve plug 202, a valve stem 203, and a valve head 204. A container 100 is provided at the bottom of the spray mechanism 200. The container 100 is a tank containing propellant and spray liquid. The valve seat 201 is fixedly connected to the container 100, the valve plug 202 is rotatably connected to the valve seat 201, and the valve stem 203 is slidably connected to the valve plug 202.

[0028] Valve seat 201 is a hollow column. Several sets of connecting pipes 201a are connected to the bottom of valve seat 201, communicating with the interior of valve seat 201. A base 201b is located at the axial center of the bottom of the inner wall of valve seat 201. A groove 201b-1 is formed on the outer wall of base 201b. Valve plug 202 has the same number of inlet valve holes 202a as the connecting pipes 201a. The opening area of ​​the several sets of inlet valve holes 202a increases in the same direction. A retaining ring 202b is provided on the inner wall of valve plug 202, and the retaining ring 202b engages with the groove 201b-1. Inside, valve 202 and valve seat 201 are rotatably connected by snap ring 202b and snap groove 201b-1. Under normal conditions, the connecting pipes 201a of valve seat 201 are all blocked by connecting pipes 201a. When valve 202 starts to rotate, since the opening area of ​​water inlet valve hole 202a increases in the same direction, after valve 202 starts to rotate, several sets of connecting pipes 201a will gradually overlap with several sets of water inlet valve holes 202a as valve 202 rotates. In this way, the spraying volume of spraying liquid is adjusted.

[0029] A connector 203a is provided at the bottom of the valve stem 203. Limiting grooves are provided at the top of the outer wall of the base 201b and at the bottom of the connector 203a. The connector 203a is slidably connected inside the base 201b. A spiral groove 202c is provided on the inner wall of the valve plug 202. A protrusion 203b is provided on the outer wall of the connector 203a. The protrusion 203b is slidably connected inside the spiral groove 202c of the valve plug 202. Due to the limiting of the connector 203a and the base 201b, and the metering hole 203d and the spiral groove 202c, when the valve stem 203 moves up and down, it will drive the connector 203a to slide inside the base 201b, thereby driving the valve plug 202 to rotate inside the valve seat 201.

[0030] A gas inlet valve hole 201c is provided through the outer wall of the valve seat 201. A metering hole 203d is provided on the outer wall and top of the valve stem 203. A sealing ring is provided on the inner wall of the valve seat 201, and the sealing ring is at the same height as the metering hole 203d on the side wall of the valve stem 203. Under normal conditions, the metering hole 203d on the outside of the valve stem 203 is blocked by the sealing ring of the valve seat 201. When the valve stem 203 moves up and down, the metering hole 203d will be misaligned with the sealing ring. At this time, since the container 100 is filled with propellant, the propellant located at the top of the container 100 pushes the spraying liquid through the connector 203a and the water inlet valve hole 202a into the valve seat 201. At the same time, the propellant is injected into the valve seat 201 through the gas inlet valve hole 201c. The propellant and the spraying liquid mix and are injected through the metering hole 203d and flow out from the top of the valve stem 203.

[0031] The valve head 204 is snapped into the valve stem 203. The valve head 204 has an atomizing chamber 204a inside and a spray hole 204b through the outer wall of the valve head 204. When the propellant and the spraying liquid are mixed, they are discharged into the valve head 204 through the metering hole 203d and atomized inside the atomizing chamber 204a. Then, they are sprayed out in the form of atomized spray through the spray hole 204b.

[0032] A spring 203c is provided at the bottom of the valve stem 203, and the other end of the spring 203c is connected to the base 201b; the spring 203c is used for the overall reset of the spray mechanism 200.

For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise altered, and the nature or number or position of discrete elements may be changed or altered.
