Fluid diverter for an atomization device

Abstract

A fluid diverter for an atomization device includes a body. The body includes opposite first and second sides. The first side has, radially outward from the central axis of the body, a central region, an annular trench surrounding the central region and recessed toward the second side, and a ramp region surrounding the annular trench. The central region is recessed from the first side toward the second side to define an inlet trench communicating with the annular trench. The annular trench has a trench width along each radial direction from the central axis, and the trench width has a starting width and a terminating width along the rotational direction around the central axis at the junction of the annular trench and its inlet trench, and the trench width decreases in the rotational direction from the starting width toward the terminating width. The ramp region is inclined along each radial direction outward from the central axis in an inclined direction toward the second side or away from the second side at its junction with the annular trench. The fluid diverter for the atomization device is only provided with an inlet flow channel, an annular trench and a ramp region, without a large number of diversion channels for diverting the fluid, thus simplifying the structure.

Description

Technical Field

[0001] The present invention relates to a fluid diversion member, and particularly to a fluid diverter for an atomization device. Background Art

[0002] In various technical industries, when it is necessary to cover a material over a large area or perform granulation, an atomization device is mostly required for implementation. Generally speaking, the basic components of an existing atomization device include a gas pipeline for inputting a gas, a liquid pipeline for inputting a liquid, and a confluence module. The confluence module is provided with a fluid diverter for receiving the liquid from the aforementioned liquid pipeline and the gas from the aforementioned gas pipeline and outputting them out of the existing atomization device.

[0003] In existing atomization devices, most of them focus on the design of the external form, but the homogenization of the fluid is the main factor affecting the overall performance of the atomization device. To ensure the stability of the fluid flow direction, the flow channel design of the existing fluid diverter is based on the cross-sectional area of the fluid supply end being larger than the cross-sectional area of the fluid outlet end (that is, one-in-multiple-out).

[0004] Refer to Figure 1 and Figure 2 , an existing fluid diverter 1, which includes an inlet channel 11 for receiving a fluid 10, a plurality of diverging channels 12 arranged at annular intervals and communicating with the inlet channel 11 for diverting the fluid 10, and an outlet slit 13 arranged in a ring and communicating with the diverging channels 12 and collecting the fluid 10 in the diverging channels 12.

[0005] Specifically Figure 1 and Figure 2 the fluid diverter 1 shown has a fluid flow direction in which the diverging channels 12 between the upper layer and the lower layer are offset by 1 / 4. Figure 3 and Figure 4 the fluid diverter 1 shown has a fluid flow direction in which the diverging channels 12 between the upper layer and the lower layer are offset by 1 / 2, while Figure 5 and Figure 6 the fluid diverter 1 shown has a fluid flow direction in which the diverging channels 12 between the upper layer and the lower layer are arranged in alignment. Although the fluid diverter 1 can achieve the effect of diverting the fluid 10. However, the one-in-multiple-out flow channel design often leads to an intensification of the interaction between fluids. Especially in the flow channel design of multiple diverging channels 12, even if the flow rate at the outlet of each diverging channel 12 is stable; however, there is still an interaction between adjacent diverging channels 12, resulting in the problem that the fluid cannot be homogenized.

[0006] The applicant uses computational fluid dynamics (hereinafter referred to as CFD) to sample and simulate the flow velocity of the existing fluid diverter 1. The flow velocity is sampled from the outlet slit 13 of the lowermost flow dividing channel 12 of the existing fluid diverter 1, and the sampling condition is to sample 20 points with each 18° as a sampling point (please see Figure 7 ), and the fluid 10 flowing into the existing fluid diverter 1 and the flow rate are set to be liquid and 40 L / hr respectively. According to Figure 8 and the flow velocity sampling simulation results shown in Table 1, although the best flow dividing effect is achieved when there is a 1 / 2 offset between the upper and lower flow dividing channels 12; however, whether there is an offset or alignment between the upper and lower flow dividing channels 12, the flow velocities of the sampling points all fluctuate between 0.18 M / sec. and 0.155 M / sec., and the coefficient of variation is as high as between 5.24% and 6.18%, which proves that there is an interaction between adjacent flow dividing channels 12 so that the fluid 10 cannot be homogenized. Therefore, even though the existing fluid diverter 1 can achieve a flow dividing effect on the fluid 10, it cannot homogenize the flow velocity of the fluid 10 flowing to the outlet slit 13.

[0007] Table 1.

[0009]

[0010] In addition, Figure 1 、 Figure 3 and Figure 5 for the existing fluid diverter 1 shown, the spaces of its inlet flow channel 11, each flow dividing channel 12 and the outlet slit 13 are actually jointly defined by the metal frame of the atomizing device and the metal pipeline for supplying fluid transportation. Moreover, in order to achieve actions such as offset and alignment between the upper and lower flow dividing channels 12, more complex components are required to complete. Therefore, in addition to the problem that the fluid cannot be homogenized, the structural design of the existing fluid diverter 1 is also very complex.

[0011] As can be seen from the above description, it is a problem to be solved by those skilled in the art to simplify the structure of the fluid diverter while solving the problem of fluid homogenization. Summary of the Invention

[0012] The purpose of the present invention is to provide a fluid diverter for an atomizing device that can improve fluid uniformity and simplify the structure.

[0013] The fluid diverter for an atomizing device of the present invention is used to divert fluid and includes a body. The body includes a first side and a second side disposed opposite to each other. The first side sequentially has a central region, an annular trench surrounding the central region and recessed toward the second side, and a ramp region surrounding the annular trench along the radial direction from the central axis of the body. The central region is recessed from the first side toward the second side to define an inlet trench communicating with the annular trench. The annular trench has a trench width along each radial direction from the central axis, and the trench width has a starting width (Wx) and an ending width (W0) along a first rotation direction around the central axis from the junction of the annular trench and its inlet trench, and the trench width decreases along the first rotation direction from the starting width (Wx) toward the ending width (W0). The ramp region is inclined in a direction toward the second side or away from the second side along each radial direction from the central axis outward from its junction with the annular trench.

[0014] For the fluid diverter for an atomizing device of the present invention, the inclination direction of the ramp region on the first side of the body of the fluid diverter is inclined from the central axis along each radial direction outward from the junction of the ramp region and the annular trench toward the second side.

[0015] For the fluid diverter for an atomizing device of the present invention, the inclination direction of the ramp region on the first side of the body of the fluid diverter is inclined from the central axis along each radial direction outward from the junction of the ramp region and the annular trench away from the second side.

[0016] For the fluid diverter for an atomizing device of the present invention, the body further includes at least one inlet through-hole that penetrates the first side and the second side of the body and is located in the central region of the first side. The second side of the body sequentially has a central region configured with the inlet through-hole, an annular trench surrounding its central region and recessed toward the first side, and a ramp region surrounding its annular trench along the radial direction from the central axis. In the present invention, the central region of the second side is recessed from the second side toward the first side to have an inlet trench communicating with the annular trench on the second side, and the inlet trench on the second side communicates with the inlet through-hole; the annular trench on the second side has a trench width along each radial direction from the central axis, and the trench width on the second side has a starting width (Wx) and an ending width (W0) along a second rotation direction around the central axis from the junction of its annular trench and its inlet trench, and the trench width on the second side decreases along the second rotation direction from its starting width (Wx) toward its ending width (W0); the inclination direction of the ramp region on the second side of the body of the fluid diverter is inclined from the central axis along each radial direction outward from the junction of its ramp region and its annular trench toward the first side or away from the first side.

[0017] The beneficial effects of the present invention are as follows: only configured with the inlet flow channel, the annular ditch and the slope area, there is no need for a large number of diversion channels to divert the fluid, the structure is simplified, and the fluid can be expanded bidirectionally along the annular ditch to the entire circumference and then uniformly expanded towards the slope area. On the one hand, the decreasing ditch width is used to assist the expansion speed of the fluid in the annular ditch, and the termination width is used to share the buffer time for the fluid to expand upwards to the slope area. On the other hand, relying on the inclination direction of the slope area, the fluid expanding from the annular ditch to the slope area expands uniformly and continuously radially outward along the central axis.

[0040] Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

[0041] Refer to Figure 9 、 Figure 10 and Figure 11 In a first embodiment of a fluid diverter for an atomization device according to the present invention, it is installed in an atomization device (not shown in the figure) and is used to divert a fluid (not shown in the figure) so that the diverted fluid is ejected through an outlet slit (not shown in the figure) of the atomization device. The fluid diverter of the first embodiment of the present invention includes a body 2 made of stainless steel. The body 2 includes a first side 21 and a second side 22 disposed opposite to each other. In the first embodiment of the present invention, the appearance of the body 2 is in the shape of a disc, and the first side 21 and the second side 22 are respectively the upper side and the lower side of the disc-shaped body 2.

[0042] The first side 21 has, in sequence from the central axis a of the body 2 radially outward, a central region 211, an annular groove 212 surrounding the central region 211 and recessed toward the second side 22, and a slope region 213 surrounding the annular groove 212.

[0043] The central region 211 is recessed from the first side 21 toward the second side 22 to define an inlet groove 2111 communicating with the annular groove 212. The annular groove 212 has a groove width in each radial direction from the central axis a, and the groove width has a starting width Wx and a terminating width W0 from the junction of the annular groove 212 and its inlet groove 2111 along a first rotation direction R1 around the central axis a, and the groove width decreases from the starting width Wx toward the terminating width W0 along the first rotation direction R1. The slope region 213 is inclined in an inclined direction from the central axis a in each radial direction outward from its junction with the annular groove 212 toward the second side 22 or away from the second side 22.

[0044] Furthermore, when the fluid is a gas, since the gas is not affected by gravity; therefore, the inclined direction is from the central axis a in each radial direction outward from the junction of the slope region 213 and the annular groove 212 toward the second side 22. When the fluid is a liquid, since the liquid is affected by gravity; therefore, the inclined direction is from the central axis a in each radial direction outward from the junction of the slope region 213 and the annular groove 212 away from the second side 22.

[0045] Specifically, in the first embodiment of the present invention, the first side 21 of the body 2 of the fluid diverter is for diverting gas, and the inclination direction of the ramp area 213 on the first side 21 of the body 2 is as Figure 11 shown, slanting from the central axis a radially outward from the junction of the ramp area 213 and the annular trench 212 towards the second side 22 (that is, slanting radially outward towards the lower side).

[0046] Refer to Figure 12 , Figure 13 and Figure 14 . A second embodiment of the fluid diverter for an atomizing device of the present invention is substantially the same as the first embodiment. The difference is that the first side 21 of the body 2 of the fluid diverter in the second embodiment of the present invention is for diverting liquid. Specifically, the inclination direction of the ramp area 213 on the first side 21 of the body 2 is as Figure 14 shown, slanting from the central axis a radially outward from the junction of the ramp area 213 and the annular trench 212 away from the second side 22 (that is, slanting radially outward towards the upper side). It should be further noted here that Figure 13 the so-called starting width Wx is the width of the trench obtained by extending radially outward from the central axis a and tangentially extending the tangent line to the lower side of the inlet trench 2111 to the junction of the annular trench 212 and the ramp area 213, and the so-called ending width W0 is the width of the trench obtained by extending radially outward from the central axis a and tangentially extending the tangent line to the upper side of the inlet trench 2111 to the junction of the annular trench 212 and the ramp area 213.

[0047] Although the second embodiment of the present invention is based on the fluid being a liquid affected by gravity, so that the inclination direction is as Figure 14 shown, slanting from the central axis a radially outward from the junction of the ramp area 213 and the annular trench 212 away from the second side 22 (that is, slanting radially outward towards the upper side). However, it should be further noted here that when the flow rate of the liquid is greatly increased, the inclination direction of the ramp area 213 can also be slanting radially outward towards the lower side like the first embodiment.

[0048] Refer to Figure 15 and Figure 16 . The applicant also uses CFD to perform a sampling simulation of the flow velocity of the fluid diverter in the second embodiment of the present invention. The sampling conditions are also taking 20 sampling points at every 18° (please see Figure 15 ), and setting the fluid and flow rate flowing into the fluid diverter of the second embodiment to be liquid and 40 L / hr respectively, and setting three groups of conditions for the gap of the outlet slit (not shown in the figure) of the atomizing device to be 0.1 mm, 0.15 mm, and 0.2 mm.

[0049] Table 2

[0050]

[0051] According to Figure 16 the flow velocity sampling simulation results shown in Table 2 above, reducing the gap of the outlet slit can increase the fluid flow velocity, and increasing the gap of the outlet slit can decrease the fluid flow velocity. In addition, when the outlet slit gap is set to 0.1 mm, the flow velocity obtained from the sampling point only falls between approximately 0.319 M / sec. and 0.331 M / sec., with little fluctuation in the flow velocity and stable flow velocity, and its coefficient of variation is only 1.36%; when the outlet slit gap is set to 0.15 mm, the flow velocity obtained from the sampling point also only falls between approximately 0.214 M / sec. and 0.223 M / sec., the fluctuation of the flow velocity is less than the condition where the outlet slit gap is 0.1 mm and the flow velocity is quite stable, and its coefficient of variation is only 1.35%; when the outlet slit gap is set to 0.2 mm, the flow velocity obtained from the sampling point also approximately falls between 0.093 M / sec. and 0.098 M / sec., with little fluctuation in the flow velocity and stable flow velocity, and its coefficient of variation is only 1.54%. Through the above simulation description, it can be confirmed that in the second embodiment of the present invention, whether the outlet slit is increased or reduced, the liquid can present a nearly uniform flow velocity at each sampling point and achieve the effect of flow velocity homogenization.

[0052] Specifically, the liquid introduced from the inlet ditch 2111 of the second embodiment of the present invention into the annular ditch 212 can expand bidirectionally in the circumferential direction of the annular ditch 212 to the full circumference and then uniformly expand toward the slope area 213; wherein, the target flow velocity of the liquid flowing into the convergence point of the annular ditch 212 is set to 1 / 2 of the average velocity to determine the decreasing amount of the ditch width of the annular ditch 212. More specifically, on the one hand, the second embodiment of the present invention utilizes the structure of the decreasing ditch width of the annular ditch 212 to assist the expansion speed of the liquid in the annular ditch 212, and the buffer time for the liquid to expand upward to the slope area 213 is shared by the width of the termination width W0; on the other hand, relying on the inclination direction of the slope area 213, the liquid expanding from the annular ditch 212 to the slope area 213 uniformly and continuously expands radially outward and upward from the central axis a.

[0053] Refer to Figure 17 、 Figure 18 and Figure 19 A third embodiment of the fluid diverter for the atomization device of the present invention is substantially the same as the second embodiment, and the difference is that the third embodiment of the present invention is used to simultaneously divert gas and liquid.

[0054] Specifically, the body 2 of the third embodiment of the present invention further includes at least one inlet through-hole 20. The inlet through-hole 20 penetrates the first side 21 and the second side 22 of the body 2 and is located in the central area 211 of the first side 21.

[0055] On the second side 22 of the body 2, there are, in sequence along the radial direction outward from the central axis a, a central area 221 where the inlet through-hole 20 is disposed, an annular groove 222 that surrounds the central area 221 and is recessed toward the first side 21 to be defined, and a slope area 223 that surrounds the annular groove 222.

[0056] In the central area 221 of the second side 22, there is an inlet groove 2211 that is recessed from the second side 22 toward the first side 21 and communicates with the annular groove 222 of the second side 22, and the inlet groove 2211 of the second side 22 communicates with the inlet through-hole 20. The annular groove 222 of the second side 22 has a groove width along each radial direction from the central axis a, and the groove width of the second side 22 has a starting width Wx and a terminating width W0 along a second rotation direction R2 that surrounds the central axis a from the junction of its annular groove 222 and its inlet groove 2211. The groove width of the second side 22 decreases along the second rotation direction R2 from its starting width Wx toward its terminating width W0. In the third embodiment of the present invention, the second rotation direction R2 is opposite to the first rotation direction R1. The inclination direction of a slope area 223 on the second side 22 of the body 2 of the fluid diverter is inclined outward along each radial direction from the central axis a from the junction of its slope area 223 and its annular groove 222 toward the first side 21 or away from the first side 21.

[0057] In the third embodiment of the present invention, the inclination direction of the slope area 223 on the second side 22 of the body 2 is as Figure 19 shown, inclined outward along each radial direction from the central axis a from the junction of its slope area 223 and its annular groove 222 toward the first side 21 (that is, inclined radially outward and upward), for diverting gas. Specifically, when the third embodiment of the present invention is used in the atomizing device (not shown in the figure), the liquid can flow sequentially from the inlet groove 2111 on the first side 21 of the body 2 to the annular groove 212 and the slope area 213, and the gas can be introduced through the inlet through-hole 20 of the body 2 via the input pipeline (not shown in the figure) of the atomizing device and flow sequentially through the inlet groove 2211, the annular groove 222, and the slope area 223 on the second side 22. When the liquid and the gas respectively expand radially outward and upward simultaneously in the slope area 213 on the first side 21 and the slope area 223 on the second side 22, they can impact each other at the outer edges of the slope area 213 on the first side 21 and the slope area 223 on the second side 22. To clearly illustrate the usage state when the embodiment described in the present invention is actually used in the atomizing device, the applicant specifically uses the following Figure 20 andFigure 21 to assist in explaining the flow direction and impact state of the fluid and the liquid after flowing into each embodiment.

[0058] Refer to Figure 20 , which shows a usage state diagram of the embodiment of the present invention installed in a four-fluid atomization device 3, and Figure 20 is an external mixing type four-fluid atomization device 3. Relevant explanations regarding external mixing will be described later.

[0059] Specifically, the four-fluid atomization device 3 includes an upper base 31 and a lower base 32 that are spaced apart from each other along the central axis a of each embodiment, and further includes four input pipes 33 that penetrate the upper base 31; wherein, the embodiments of the present invention are sandwiched between the upper base 31 and the lower base 32, and are, in order from top to bottom, the first embodiment, the second embodiment, and the third embodiment. Two of the four input pipes 33 are used to respectively input a first gas and a second gas, and the remaining two of the four input pipes 33 are used to respectively input a first liquid and a second liquid. The first and second embodiments installed in the four-fluid atomization device 3 are further configured with through holes (not shown in the figure) that penetrate the first and second sides 21, 22 of each body 2 and are located in the central regions 211 to communicate with the aforementioned input pipes 33 to introduce liquid and gas.

[0060] Specifically, when the first and second gases are respectively introduced from two of the input pipes 33 into the inlet ditch 2111 on the first side (upper side) 21 of the body 2 of the first embodiment and the inlet ditch 2211 on the second side (lower side) 22 of the body 2 of the third embodiment, the first gas can flow from the inlet ditch 2111 on the first side (upper side) 21 of the body 2 of the first embodiment to its annular ditch 212 in sequence and radially expand downward and outward toward its slope region 213, and the second gas can flow from the inlet ditch 2211 on the second side (lower side) 22 of the body 2 of the third embodiment to its annular ditch 222 in sequence and radially expand upward and outward toward its slope region 223. In addition, when the first and second liquids are respectively introduced from the remaining two input pipes 33 into the inlet ditch 2111 on the first side (upper side) 21 of the body 2 of the second embodiment and the inlet ditch 2111 on the first side (upper side) 21 of the body 2 of the third embodiment, the first liquid can flow from the inlet ditch 2111 on the first side (upper side) 21 of the body 2 of the second embodiment to its annular ditch 212 in sequence and radially expand upward and outward toward its slope region 213, and the second liquid can flow from the inlet ditch 2111 on the first side (upper side) 21 of the body 2 of the third embodiment to its annular ditch 212 in sequence and radially expand upward and outward toward its slope region 213.

[0061] Therefore, while the first gas expands radially outward and downward in the ramp area 213 on the first side (upper side) 21 of the body 2 in the first embodiment, the first liquid expands radially outward and upward in the ramp area 213 on the first side (upper side) 21 of the body 2 in the second embodiment, causing the first gas and the first liquid to impact each other at the outer periphery of the ramp area 213 on the first side (upper side) 21 of the body 2 in the first embodiment and the outer periphery of the ramp area 213 on the first side (upper side) 21 of the body 2 in the second embodiment, respectively. Similarly, while the second gas expands radially outward and upward in the ramp area 223 on the second side (lower side) 22 of the body 2 in the third embodiment, the second liquid expands radially outward and upward in the ramp area 213 on the first side (upper side) 21 of the body 2 in the third embodiment, causing the second gas and the second liquid to impact each other at the outer periphery of the ramp area 223 on the second side (lower side) 21 of the body 2 in the third embodiment and the outer periphery of the ramp area 213 on the first side (upper side) 21 of the body 2 in the third embodiment, respectively. As shown at Figure 20 the point A marked at A is the first impact point A of the second gas and the second liquid.

[0062] Referring again to Figure 20 , the upper base 31 has a top wall 311 and a surrounding wall 312 extending downward from a peripheral edge of the top wall 311. The lower base 32 has a bottom wall 321 and a surrounding wall 322 extending upward from a peripheral edge of the bottom wall 321. As shown by Figure 20 , the horizontal height of a bottom edge of the surrounding wall 312 of the upper base 31 is higher than the outer periphery of the ramp area 213 on the first side (upper side) 21 of the bodies 2 in the first and second embodiments, and an upper side outlet slit is formed between the bottom edge of the surrounding wall 312 of the upper base 31 and the outer periphery of the ramp area 213 on the first side (upper side) 21 of the bodies 2 in the first and second embodiments; while the horizontal height of a top edge of the surrounding wall 322 of the lower base 32 is lower than the junction of the outer periphery of the ramp area 213 on the first side (upper side) 21 and the outer periphery of the ramp area 223 on the second side (lower side) 22 of the body 2 in the third embodiment, and a lower side outlet slit is formed between the top edge of the surrounding wall 322 of the lower base 32 and the junction of the outer periphery of the ramp area 213 on the first side (upper side) 21 and the outer periphery of the ramp area 223 on the second side (lower side) 22 of the body 2 in the third embodiment. It can be seen from this that the first impact point A described above is located outside the upper base 31 and the lower base 32 of the four-fluid atomization device 3. Therefore, the second gas and the second liquid impact and mix outside the four-fluid atomization device 3; similarly, the first gas and the first liquid also impact and mix outside the four-fluid atomization device 3. After the first gas and the first liquid and the second gas and the second liquid impact and mix into a first gas-liquid mixed fluid and a second gas-liquid mixed fluid, respectively, the first and second gas-liquid mixed fluids will follow their own inertia in Figure 20The impact mixing at the marked position B ejects the final granulated particles radially outward; among which, Figure 20 the marked position B is the second impact point B. From the foregoing description, it can be known that the so-called external mixing means that the first impact point A of the gas and the liquid is located outside the four-fluid atomization device 3.

[0063] Refer to Figure 21 , which shows the usage state diagram of the embodiment of the present invention installed in the four-fluid atomization device 3, and Figure 21 it is an internal mixing type four-fluid atomization device. From Figure 21 the display, it can be known that the horizontal height of the bottom edge of the surrounding wall 312 of the upper base 31 is lower than the outer periphery of the slope area 213 on the first side (upper side) 21 of the body 2 of the first and second embodiments, and the horizontal height of the top edge of the surrounding wall 322 of the lower base 32 is higher than the intersection of the outer periphery of the slope area 213 on the first side (upper side) 21 and the outer periphery of the slope area 223 on the second side (lower side) 22 of the body 2 of the third embodiment. Thus, it can be known that the first impact point A is located inside the upper base 31 and the lower base 32 of the four-fluid atomization device 3; therefore, the second gas and the second liquid are mixed by impact inside the four-fluid atomization device 3; similarly, the first gas and the first liquid are also mixed by impact inside the four-fluid atomization device 3. Although the present invention uses Figure 20 and Figure 21 the four-fluid atomization device 3 shown to illustrate the usage state of the embodiment. However, it should be noted that the embodiment is not limited to being applied to a four-fluid atomization device, and it can also be applied to a two-fluid atomization device or a three-fluid atomization device.

[0064] Here, it needs to be further supplemented and explained that those skilled in the relevant art know that spray granulation generally makes a product formed by the rapid impact mixing of a liquid (such as a solution or slurry mixed with a solvent, ceramic powder, and dispersant) and a gas. However, the key to determining the particle size of the final granulated particles depends on the gas content in the total amount of the gas-liquid mixed fluid. That is to say, when the gas content in the total amount of the gas-liquid mixed fluid is higher, the particle size of the finally produced granulated particles will be finer. However, while the particle size of spray granulation is reduced, it is also limited by the gas pressure. Therefore, it is often difficult to reduce the particle size of spray granulation.

[0065] However, in the structural design of the annular trenches 212, 222 and the slope regions 213, 223 of the embodiments of the present invention, in addition to the simple structure that does not require a large number of flow channels 12 like the existing fluid diverter 1, more notably, taking the third embodiment of the present invention as an example, the present invention can increase the diameter size of the body 2 of the third embodiment, so as to increase the trench width of the annular trench 222 on the second side (lower side) 22 of the body 2, so as to supply a high flow rate of gas under the condition of not being restricted by gas pressure, thereby greatly increasing the gas content in the total amount of gas-liquid mixed fluid, and achieving the effect of refining the granule size by this means.

[0066] As can be seen from the above detailed description of the present invention, the structural design of the embodiments of the present invention is more simplified than the structure of the existing fluid diverter 1, and does not require a large number of flow channels 12 like the existing fluid diverter 1. In addition, the liquid flow rate led out from the second embodiment of the present invention is also more uniform than that of the existing fluid diverter 1. Moreover, when actually applied to an atomization device, the width of the annular trench 212 on the first side 21 of the body 2 of the first embodiment and the width of the annular trench 222 on the second side 22 of the body 2 of the third embodiment can be enlarged by increasing the diameter size of the body 2 of the said embodiment, so as to increase the gas flow rate under the condition of not being restricted by gas pressure, thereby increasing the gas content in the total amount of gas-liquid mixed fluid and refining the particle size of the finally produced granules.

[0067] In summary, the fluid diverter for an atomization device of the present invention not only has a simplified structure, but also the liquid flow rate led out from the fluid diverter of the present invention is very uniform, so it can indeed achieve the purpose of the present invention.

[0068] The above are only the embodiments of the present invention, and the scope of implementation of the present invention cannot be limited by this. All simple equivalent changes and modifications made according to the claims and the content of the specification of the present invention still fall within the scope covered by the present invention.
