Abstract
Description
Technical Field
[0001] This utility model relates to the field of atomizer technology, and more particularly to centrifugal atomizers. Background Technology
[0002] A centrifugal nebulizer is a device that uses centrifugal force to atomize liquids into fine particles, and it is widely used in medical, agricultural and industrial fields.
[0003] Centrifugal atomizers generate centrifugal force through high-speed rotation, driven by a motor. However, the motor's speed is limited by its size and materials; exceeding a certain speed may cause overheating, accelerated wear, or even damage. Without replacing the motor, the centrifugal force and atomization effect of a centrifugal atomizer are limited.
[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a centrifugal atomizer to improve the atomization effect of the centrifugal atomizer.
[0006] The technical solution of this utility model is as follows:
[0007] A centrifugal atomizer, the atomizer comprising a frame, a motor, a transmission assembly, a main shaft, and an atomizing disc;
[0008] The motor is mounted on the frame;
[0009] The transmission assembly includes a first transmission gear, a second transmission gear, a third transmission gear, and a transmission shaft; the first transmission gear is disposed on the output shaft of the motor; the second transmission gear is disposed on the transmission shaft, which is disposed on the frame; and the third transmission gear is disposed on the main shaft.
[0010] The spindle is mounted on the frame;
[0011] The atomizing disk is mounted on the main shaft;
[0012] Wherein, the first transmission tooth meshes with the second transmission tooth, and the second transmission tooth meshes with the third transmission tooth; the transmission ratio between the first transmission tooth and the third transmission tooth is <1.
[0013] A further technical solution is that the first transmission gear, the second transmission gear, and the third transmission gear are driven by helical gears.
[0014] A further technical solution is that the first transmission tooth, the second transmission tooth, and the third transmission tooth each include a helical gear set; the helical gear set includes two identical helical gears, one above the other, with the helical gears in the same helical gear set rotating in opposite directions; the first transmission tooth and the second transmission tooth are driven by meshing of the two helical gear sets; the second transmission tooth and the third transmission tooth are driven by meshing of the two helical gear sets.
[0015] A further technical solution is that the second transmission gear includes at least two sets of gears, and the number of teeth in different sets of gears is different.
[0016] A further technical solution is that the frame is also provided with a transmission housing; a seat hole is opened in the transmission housing; the output shaft, transmission shaft and main shaft are rotatably connected to the transmission housing through bearings and the seat hole.
[0017] A further technical solution is that a sleeve extends from the transmission housing, and the main shaft extends out of the transmission housing along the sleeve.
[0018] A further technical solution is that a bushing is also provided, the bushing flange is connected to the sleeve, and the bushing is sleeved on the main shaft; the lower end of the main shaft is away from the transmission assembly and extends out of the bushing, and the atomizing disc is located at the lower end of the main shaft.
[0019] A further technical solution is that a cone is also provided on the frame; the cone is sleeved on the main shaft; the large-diameter end of the cone is connected to the frame; the main shaft extends out of the cone along the small-diameter end of the cone.
[0020] A further technical solution is that a flange extends from the inner wall of the cone; the flange forms an inner diameter section with a rectangular cross-section inside the cone, and the flange supports the main shaft.
[0021] A further technical solution is that the frame includes a square base and support rods; at least three support rods are arranged on the square base, and the upper part of the support rods is inclined towards the main shaft; the support rods support the motor, the transmission assembly, the main shaft and the atomizing disc.
[0022] The beneficial technical effects of this utility model are as follows:
[0023] (1) The centrifugal atomizer in this utility model is equipped with a transmission assembly. The rotational speed output by the motor is transmitted to the main shaft along the output shaft and transmission shaft of the motor. The rotational speed is transmitted between the output shaft, transmission shaft, and main shaft through a first transmission gear, a second transmission gear, and a third transmission gear. The transmission ratio from the first transmission gear to the third transmission gear is <1. That is, the rotational speed output by the motor is amplified by the transmission assembly, so that the main shaft drives the atomizing disc at a higher rotational speed. The higher rotational speed can generate a greater centrifugal force, so that the liquid is rapidly atomized into fine droplets under the action of a large centrifugal force. The droplet size is more uniform, and the droplet velocity is higher, and the spray distance and coverage area will also increase accordingly, thus optimizing the atomization effect of the centrifugal atomizer. By increasing the speed through the transmission assembly, even a motor with a lower rotational speed can drive the main shaft to rotate at a high speed. This avoids the impact of replacing a high-speed motor on the size and cost of the centrifugal atomizer.
[0024] (2) Furthermore, the first, second, and third transmission gears are driven by helical gears. Helical gears offer better meshing and can effectively reduce energy loss. Additionally, the larger tooth surface contact area of helical gears allows them to withstand higher loads and achieve a larger transmission ratio, facilitating the amplification of the motor's output speed.
[0025] (3) Further, the first transmission gear, the second transmission gear, and the third transmission gear each include a helical gear set; the helical gear set includes two helical gears of the same size but with opposite directions of rotation. When the helical gear sets mesh, the axial forces generated by the helical gears on the same shaft can cancel each other out, reducing the axial force on the shaft. Attached Figure Description

[0033] Figure 1 A three-dimensional structural schematic diagram of the centrifugal atomizer of this utility model is shown. Figure 2 A three-dimensional structural schematic diagram of the transmission assembly in the centrifugal atomizer of this utility model is shown. Please refer to it. Figure 1 and Figure 2The centrifugal atomizer includes a frame 1, a motor 2, a transmission assembly 5, a main shaft 6, and an atomizing disc 8. The motor 2 is mounted on the frame 1. The transmission assembly 5 includes a first transmission gear 51, a second transmission gear 52, a third transmission gear 53, and a transmission shaft 54. The first transmission gear 51 is mounted on the output shaft 21 of the motor 2. The second transmission gear 52 is mounted on the transmission shaft 54, which is mounted on the frame 1. The second transmission gear 52 includes at least two sets of gears with different numbers of teeth in each set. The third transmission gear 53 is mounted on the main shaft 6. The rotational speed output by the motor 2 is transmitted to the main shaft 6 along the output shaft 21 and the transmission shaft 54. The main shaft 6 is mounted on the frame 1. The atomizing disc 8 is mounted on the main shaft 6. Specifically, the first transmission gear 51 meshes with the second transmission gear 52, and the second transmission gear 52 meshes with the third transmission gear 53. The transmission ratio between the first transmission gear 51 and the third transmission gear 53 is less than 1. That is, the transmission assembly 5 amplifies the rotational speed output by the motor 2, allowing the main shaft 6 to drive the atomizing disc 8 at a higher rotational speed. Higher rotational speeds generate greater centrifugal force, rapidly atomizing the liquid into fine droplets. This results in more uniform droplet size and higher droplet velocity, increasing the spray distance and coverage area, thus optimizing the atomization effect of the centrifugal atomizer. The transmission component 5 speeds up the process, allowing even a slower motor 2 to drive the main shaft 6 at high speeds. This avoids the impact on the size and cost of the centrifugal atomizer caused by replacing the motor 2 with a high-speed one.
[0034] Please refer to Figure 2 The first transmission gear 51, the second transmission gear 52, and the third transmission gear 53 are driven by helical gears. Helical gears offer better meshing and can effectively reduce energy loss. Furthermore, the larger tooth surface contact area of helical gears allows them to withstand higher loads and achieve a larger transmission ratio, facilitating the amplification of the output speed of motor 2.
[0035] Preferably, the first transmission gear 51, the second transmission gear 52, and the third transmission gear 53 each include a helical gear set. Each helical gear set includes two identical helical gears, one above the other, with opposite directions of rotation. The first transmission gear 51 and the second transmission gear 52 are driven by the meshing of these two helical gear sets. Similarly, the second transmission gear 52 and the third transmission gear 53 are driven by the meshing of these two helical gear sets. When the helical gear sets mesh, the axial forces generated by the helical gears on the same shaft can cancel each other out, reducing the axial force on the shaft.
[0036] Figure 3 A vertical cross-sectional view of the centrifugal atomizer of this invention is shown. Please refer to the diagram. Figure 1 , Figure 2 ,and Figure 3A transmission housing 4 is also provided on the frame 1. A seat hole 41 is provided inside the transmission housing 4. The output shaft 21, the transmission shaft 54, and the main shaft 6 are rotatably connected to the transmission housing 4 through the bearing 55 and the seat hole 41. The output shaft 21, the transmission shaft 54, and the main shaft 6 are mounted on the frame 1 through the transmission housing 4.
[0037] Preferably, a sleeve 42 extends from the transmission housing 4, and the main shaft 6 extends out of the transmission housing 4 along the sleeve 42. The sleeve 42 provides support for the main shaft 6, helping to maintain the stability and position of the main shaft 6 and ensuring the normal rotation of the main shaft 6.
[0038] More preferably, a bushing 7 is also provided, with a flange connecting the bushing 7 to the sleeve 42, and the bushing 7 is fitted onto the main shaft 6. The lower end of the main shaft 6 is away from the transmission assembly 5 and extends out of the bushing 7, and the atomizing disc 8 is located at the lower end of the main shaft 6. The bushing 7 supports the main shaft 6 extending out of the sleeve 42, further ensuring the stability and position of the main shaft 6.
[0039] Please refer to Figure 1 and Figure 3 A cone 3 is also installed on the frame 1. The cone 3 is fitted onto the main shaft 6. The larger diameter end of the cone 3 is connected to the frame 1, ensuring that the cone 3 has sufficient contact area with the frame 1 and guaranteeing the stability of the connection between the cone 3 and the frame 1. The main shaft 6 extends out of the cone 3 along the smaller diameter end of the cone 3. The smaller diameter cone 3 avoids obstructing the droplets sprayed from the atomizing disc 8 and prevents the cone 3 from affecting the atomization effect of the centrifugal atomizer. The cone 3 protects and shields the main shaft 6 and the bushing 7.
[0040] Preferably, a flange 31 extends from the inner wall of the cone 3. The flange 31 forms a rectangular cross-section inner diameter section within the cone 3, and the flange 31 supports the main shaft 6. The rectangular cross-section inner diameter section can better contact the support sleeve 7.
[0041] More preferably, the frame 1 includes a square base 11 and support rods 12. At least three support rods 12 are disposed on the square base 11, with the upper part of the support rods 12 inclined towards the main shaft 6. The support rods 12 support the motor 2, the transmission assembly 5, the main shaft 6, and the atomizing disc 8. The inclined arrangement of the support rods 12 causes them to be subjected to vertical compression and lateral bending forces. Since multiple support rods 12 are arranged around the main shaft 6, the lateral bending forces can be mutually offset among the multiple support rods 12, thereby reducing the bending force on the support rods 12.
[0042] The specific workflow of this utility model is as follows:
[0043] When the centrifugal atomizer is working, motor 2 is started. Motor 2 drives output shaft 21 to rotate, and output shaft 21 drives the first transmission gear 51 to rotate synchronously. The rotational motion output by motor 2 is transmitted to main shaft 6 along the meshing first transmission gear 51, second transmission gear 52, and third transmission gear 53. Because the transmission ratio between the first transmission gear 51 and the third transmission gear 53 is less than 1, the rotational speed output by motor 2 is accelerated and transmitted between output shaft 21, transmission shaft 54, and main shaft 6, with the rotational speed of main shaft 6 being higher than that of motor 2. The high-speed rotation of main shaft 6 drives the atomizing disc 8 to rotate at high speed. The high-speed rotation of atomizing disc 8 generates a large centrifugal force, throwing the liquid inside atomizing disc 8 out to form atomized droplets. Motor 2 continues to work, and the centrifugal atomizer continuously produces droplets.
[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
