[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an adjustable atomizer includes: a base tube 20, which is a hollow tube, and a suction tube 21 is fixedly connected inside the cavity of the base tube 20. The suction tube 21 is a hollow round tube. An air inlet groove is provided on the side wall of the base tube 20, and an air inlet nozzle is installed at the air inlet groove. This is existing technology, so it will not be described in detail here.
[0030] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the adjustment structure is set at the top of the base tube 20 to control the atomization size. The adjustment structure includes: an adjustment box 30, a turntable 33, and a membrane groove 34. The adjustment box 30 is fixedly connected to the top of the base tube 20, the turntable 33 is rotatably connected to the wall of the adjustment box 30, and the membrane groove 34 is opened at the top of the turntable 33. A microporous membrane is installed in the membrane groove 34, and the position of the membrane groove 34 corresponds to the top of the suction tube 21.
[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the cavity of the adjustment box 30 is hollow, and the turntable 33 is disc-shaped. The turntable 33 is rotatably connected to the cavity of the adjustment box 30. Multiple membrane grooves 34 are arranged in a ring array on the top of the turntable 33. Each membrane groove 34 is equipped with a microporous membrane. The pore size on the surface of each microporous membrane is arranged in a ring from large to small. The adjustment structure also includes a through groove 31, a dial groove 32, and a dial shaft 36. The through groove 31 is opened at the bottom of the adjustment box 30, the dial groove 32 is opened at the top of the base tube 20, and the dial shaft 36 is rotatably connected in the dial groove 32. The top of the dial shaft 36 can also be connected to the turntable 33 through a cylinder. The dial groove 32 can be adapted to the rotation of the dial shaft 36. The cylinder connected to the pivot 36 and the turntable 33 can be driven within the through groove 31. The adjustment structure also includes a fixed groove 35, a locking ring 37, and a nozzle 38. The fixed groove 35 is opened on the peripheral wall of the turntable 33. The locking ring 37 is fixedly connected to the cavity of the adjustment box 30. The nozzle 38 is fixedly connected to the top of the adjustment box 30. The fixed groove 35 is a semi-circular groove. The locking ring 37 is a ring rod. The locking ring 37 is symmetrically arranged in the cavity of the adjustment box 30. Multiple fixed grooves 35 are evenly opened on the wall of the turntable 33. The locking ring 37 can be inserted into the fixed groove 35. The nozzle 38 is funnel-shaped. The lower end of the nozzle 38 can be aligned with the top of the suction pipe 21.
[0032] In practical use, the protective shell 24 is removed from the wall of the base tube 20, and then the air inlet on the wall of the base tube 20 is opened. When the air inlet is opened, a negative pressure is generated in the cavity of the straw 21, and the liquid at the bottom of the straw 21 is drawn into the cavity of the straw 21. The liquid moves upward from the cavity of the straw 21 and is atomized when it passes through the microporous membrane in the corresponding membrane groove 34 and is then sprayed out by the nozzle 38. When it is necessary to adjust the size of the atomized liquid, the dial 36 is rotated. The dial 36 can drive the turntable 33 to rotate synchronously. As the turntable 33 rotates, the solid groove 35 will separate from the locking ring 37. Then, when the desired atomization size is reached, the symmetrical locking ring 37 will be inserted into the corresponding solid groove 35, thereby fixing the position of the turntable 33 and aligning the membrane groove 34 with the top position of the straw 21.
[0033] In summary, by setting an adjustment structure, the microporous membranes of different sizes and the top of the straw 21 can be aligned by rotating the turntable 33 to meet the user's needs. Therefore, this solution has a wider range of applications compared to commonly used atomizers.
[0034] like Figure 1 and Figure 2 As shown, the wall of the base tube 20 is also provided with a protective structure, which includes a fixed plate 22, a support rod 23 and a protective shell 24. The fixed plate 22 is fixedly connected to the bottom end of the base tube 20. The support rod 23 is symmetrically fixedly connected to the wall between the adjustment box 30 and the fixed plate 22. The protective shell 24 is sleeved on the wall of the fixed plate 22. The fixed plate 22 and the adjustment box 30 have the same size. The support rod 23 is cylindrical. The cavity of the protective shell 24 is hollow and can be adapted to the size of the fixed plate 22.
[0035] In practical use, the protective shell 24 can be fitted onto the fixed plate 22 and cover the bottom end of the straw 21;
[0036] In summary, by setting up a protective structure, the bottom of the straw 21 is protected by the protective shell 24 when not in use, thereby preventing damage when dropped and preventing dust from entering the bottom of the straw 21 and affecting the straw 21's ability to draw liquid.
[0037] An atomic absorption spectrophotometer, not shown in the figure, includes a spectrophotometer body and an adjustable nebulizer containing all of the above.
[0038] By setting an adjustable atomizer, the applicability can be expanded by adjusting the atomization size of the liquid.
[0039] Working principle: Remove the protective shell 24 from the wall of the base tube 20, and then open the air inlet on the wall of the base tube 20. When the air inlet is opened, a negative pressure is generated in the cavity of the straw 21, and the liquid at the bottom of the straw 21 is drawn into the cavity of the straw 21. The liquid moves upward from the cavity of the straw 21 and is atomized when it passes through the microporous membrane in the corresponding membrane groove 34 and is then sprayed out by the nozzle 38. When it is necessary to adjust the size of the atomized liquid, rotate the dial 36. The dial 36 can drive the turntable 33 to rotate synchronously. As the turntable 33 rotates, the solid groove 35 will separate from the locking ring 37. Then, when the desired atomization size is reached, the symmetrical locking ring 37 will lock into the corresponding solid groove 35, thereby fixing the position of the turntable 33 and aligning the membrane groove 34 with the top of the straw 21.
