[0002] A spray pump is a pump that atomizes water droplets into fine droplets to form a water mist, suspending atomized particles or microparticles in a gas. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing the liquid's energy. It is mainly used to treat acute and chronic respiratory diseases, and can also be used in agriculture, industry, and other fields.

[0003] A search revealed that CN213529205U describes an adjustable spray pump, comprising a first cap, a second cap, and a bottle body. A clamping block is fixedly installed on the outer wall of the bottle body. A third cap is rotatably installed on the top of the bottle body. The third cap has internal threads. A second cap is fixedly installed on the top of the third cap. Telescopic devices are installed on the symmetrical inner walls of the two sides of the second cap. This invention has a novel structure and solves the problems of existing medical spray pumps being unable to adjust the spray effect and control the output volume, as well as being prone to clogging after prolonged periods of non-use.

[0004] However, the above-mentioned spray pump still has the following problems: it is inconvenient to adjust the size of the spray area during use, and it is inconvenient to adjust the amount of liquid sprayed. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0019] Please see Figure 1-2This utility model provides an adjustable spray pump technical solution: An adjustable spray pump includes a bottle cap 1, a support frame 4 fixedly connected to the bottom end of the bottle cap 1, a guide frame 5 fixedly connected to the bottom end of the support frame 4, a guide pipe 6 fixedly connected to the bottom end of the guide frame 5, a valve stem 7 vertically slidably connected inside the guide frame 5, a second spring 14 fixedly connected to the inner bottom wall of the guide frame 5, the second spring 14 being fitted onto the bottom of the valve stem 7, and an overflow groove 11 being formed in the middle of the valve stem 7. A sealing ring 12 is fitted inside the flow channel 11. A limiting ring 13 is fixedly connected to the middle of the valve stem 7, and the limiting ring 13 is located at the bottom of the sealing ring 12. A flow guide hole 10 is opened on one side of the middle of the valve stem 7. By moving the valve stem 7 downward, the flow guide hole 10 moves out from inside the sealing ring 12 and can communicate with the nozzle 22 inside the flow guide frame 5, so as to spray out liquid. The top of one side of the valve stem 7 is fixedly connected to the nozzle 22. A movable sleeve 15 is fitted on the outside of the valve stem 7. A pressing block 3 is fixedly connected to the end. Pushing the pressing block 3 downwards can drive the movable sleeve 15 to move, causing the movable sleeve 15 to push the valve stem 7 downwards. A ring frame 17 is rotatably mounted in the middle of the movable sleeve 15. A guide groove 18 is opened on the inner wall of the ring frame 17. A spray hole 21 of uniform distribution and different size is opened on the outer side of the ring frame 17. A sealing ring 20 is fixedly connected to the inner wall of the guide groove 18. The sealing ring 20 can seal the gap between the nozzle 22 and the spray hole 21 to prevent leakage. A limiting component 9 is provided on one side of the top of the nozzle 22 to limit the ring frame 17. A fixing frame 2 is fixedly connected to the middle of the top of the bottle cap 1. An adjusting component 8 is provided on the outer side of the fixing frame 2 to adjust the stroke height of the movable sleeve 15. A limiting plate 16 is fixedly connected to the bottom of the movable sleeve 15. The bottom end of the limiting plate 16 is slidably connected to the top of the inner cavity of the fixing frame 2. The limiting plate 16 can limit the stroke of the movable sleeve 15.

[0020] Please see Figure 3 The adjusting assembly 8 includes a threaded ring 81, which is threadedly connected to the outside of the fixed frame 2. Sliding holes 85 are provided on both sides of the fixed frame 2, and connecting rods 84 are slidably connected inside each sliding hole 85. A support ring 83 is fixedly connected between the two connecting rods 84, and the support ring 83 is slidably connected to the outside of the valve stem 7. An annular groove 82 is provided at the bottom of the inner wall of the threaded ring 81. The ends of the connecting rods 84 away from the support ring 83 are slidably connected inside the annular groove 82. By rotating the threaded ring 81 and rotating it upwards, the connecting rods 84 can slide inside the annular groove 82, and the support ring 83 can move upwards. This allows for adjustment of the space inside the fixed frame 2, thus facilitating the downward stroke adjustment of the valve stem 7.

[0021] Please see Figure 4The limiting component 9 includes a limiting frame 91, which is fixedly connected to the top of the nozzle 22. A first spring 92 is fixedly connected to the inner wall of the limiting frame 91. A movable block 93 is fixedly connected to one side of the first spring 92. A limiting rod 94 is fixedly connected to one side of the movable block 93. One end of the limiting rod 94 is slidably connected to one side of the limiting frame 91. The top of the inner wall of the annular frame 17 is provided with evenly distributed limiting grooves 19. One end of the limiting rod 94 is slidably connected to the inside of the limiting grooves 19. Through the pushing action of the first spring 92 on the movable block 93, one end of the limiting rod 94 can be inserted into the inside of the limiting grooves 19, which can position the adjusted annular frame 17 and prevent the annular frame 17 from rotating, so that the nozzle 22 is aligned with the corresponding spray hole 21. By rotating the annular frame 17, spray holes 21 of different sizes can be aligned with the nozzle 22, and the spray area can be adjusted.

[0022] The working principle and usage process of this utility model are as follows: The bottle cap 1 is installed in the bottle body, allowing the guide tube 6 to penetrate into the liquid. Based on the internal pressure of the bottle body, the liquid is guided into the interior of the guide frame 5. By pushing the pressing block 3 downwards, the movable sleeve 15 moves, causing the valve stem 7 to move downwards, allowing the overflow groove 11 to move out from inside the sealing ring 12, thus leaking out of the guide hole 10. The liquid inside the guide frame 5 is pushed by pressure into the interior of the guide hole 10 and atomized and sprayed out through the nozzle 22. The annular frame 17 is rotated outside the nozzle 22, causing the spray hole 21 to align with the nozzle 22. Correspondingly, the first spring 92 pushes the movable block 93, which drives the limiting rod 94 to pass through the limiting groove 19 to fix the annular frame 17 and prevent the annular frame 17 from rotating and causing the position of the spray hole 21 to shift. Then, the threaded ring 81 is rotated on the outside of the fixed frame 2 to drive the threaded transmission, so that the threaded ring 81 moves upward. During the rotation of the threaded ring 81, the connecting rod 84 slides inside the annular groove 82. As the threaded ring 81 moves upward, it drives the support ring 83 to move upward, which can shorten the moving distance of the limiting plate 16, thereby controlling the amount of liquid sprayed.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
