Description

Technical Field

[0001] This application relates to the field of atomized dust suppression, and particularly to an atomizing device for civil engineering construction. Background Art

[0002] Currently, the atomizing devices for civil engineering construction are devices for dust suppression during civil engineering construction. Common ones include fog guns or sprayers. Through the sprayed water mist particles, liquid mist dust suppression can effectively degrade polluting particulate matters, dust, etc. in the air and effectively alleviate haze.

[0003] In the related technology, the Chinese patent with the application number CN201910670945.7 proposed to use a drive assembly to adjust the angle of the air outlet of the air duct in multiple angles so that the water mist can be better distributed in more positions. However, the way the water mist is discharged outward is dense water droplets, resulting in a constant area of the water mist distribution per unit time. Adjusting the air outlet angle in multiple angles can only increase the area of the water mist distribution over a long time and is difficult to increase the area of the water mist distribution per unit time.

[0004] In the related technology, the Chinese patent with the application number CN202021326660.6 passes the process of discharging the water mist through a swirl grid, driving the atomized water droplets to move in a spiral manner, which can increase the spraying distance of the atomized water droplets; however, its spiral movement will reduce the power of the water mist movement when the water mist contacts the swirl grid. Therefore, it cannot increase the spraying distance. What can be achieved is that the spiral movement of the water mist is easy to spread around, increasing the area of the water mist distribution per unit time. However, the spiral movement will also cause the spraying distance to become shorter and the spraying range of the water mist to become smaller.

[0005] Regarding the above-mentioned related technologies: Combining the solutions of this patent into the above patent documents although increases the area of the water mist distribution per unit time, but ultimately leads to a reduction in the area of the water mist distribution over a long time, and it is difficult to balance the spraying range of the water mist and the area of the rapid distribution of the water mist. Summary of the Invention

[0006] In order to improve the problem of being difficult to balance the spraying range of the water mist and the area of the rapid distribution of the water mist, this application provides an atomizing device for civil engineering construction.

[0008] By adopting the above technical solution, the water mist is discharged in a spiral state, and the water mist itself will have centrifugal force. After the water mist is discharged outward, under the action of centrifugal force, it can better diffuse around, increasing the diffusion of the water mist into a larger space in a short time and enhancing the dust suppression effect of the water mist. The guiding member enables the water mist to be ejected obliquely outward, and the water mist ejected obliquely outward affects the water mist in the spiral fog discharge chamber. Therefore, the obliquely ejected water mist will also have a greater driving force under the action of centrifugal force, increasing the inclined range of the water mist and further increasing the diffusion speed of the water mist, thereby enhancing the dust suppression effect.

[0013] Optionally, the atomizing device for civil engineering construction further includes a water mist diffusion member arranged at a preset position. When the fog gun sprays the water mist to the preset position, the water mist diffusion member causes the water mist to diffuse around.

[0014] Optionally, the atomizing device for civil engineering construction further includes a heating element for directly or indirectly heating the flow control member to raise the temperature of the spiral mist discharge channel, the outer ring channel, and the circular channel; the temperatures of the spiral mist discharge channel, the outer ring channel, and the circular channel are all higher than the temperature of the water mist.

[0016] Optionally, the end face of the plug rod facing away from the threaded slot has a protruding portion for easy gripping; the end of the plug rod facing away from the threaded slot has a guiding protrusion, and the guiding protrusion forms a first tapered surface extending away from the axis of the plug rod on the outer wall of the plug rod; the circular channel has a second tapered surface extending away from the axis of the plug rod at the guiding protrusion; the protruding portion is located between the first tapered surface and the second tapered surface, so that the distance between the protruding portion and the axis of the plug rod is greater than the distance between the outer wall of the plug portion and the axis of the plug rod.

[0017] Optionally, the outer ring channel includes a plurality of external channels and a connecting channel communicating with the plurality of external channels; the connecting channel is docked with the air outlet; the plurality of external channels are arranged at intervals or in contact with each other outside the spiral mist discharge channel.

[0021] The following is a further detailed description of the present application in conjunction with the attached Figure 1-15 drawings.

[0022] The embodiment of the present application discloses an atomization device for civil engineering construction.

[0023] An atomization device for civil engineering construction includes: a fog gun body 1, a flow control component 2, a driving component 3, and a diversion component 4. The driving component 3 is used to provide a driving external force.

[0024] The fog gun body 1 has at least an air outlet 11 for high-speed air discharge and a water outlet 12 located at the periphery of the air outlet 11. The fog gun body 1 adopts the existing technology. The fog gun body 1 uses a fan to generate a flowing air current, and then shoots out the water mist. The flowing air current drives the water mist to flow, realizing the long-distance spraying of the water mist, so as to realize the large-scale dust reduction of the water mist. In some other solutions, the fog gun body 1 is also called a fog cannon machine.

[0025] The flow control member 2 at least has a spiral mist discharge channel 271 that docks with the air outlet 11, so that the water mist is discharged in a spiral flow state. In this embodiment, the flow control member 2 is a pipe body, and the spiral mist discharge channel 271 is formed by arranging a spiral pipe or a spiral plate 27 inside the pipe. After the water mist passes through the spiral mist discharge channel 271, the water mist will have a spiral state. Therefore, when the water mist is sprayed into the distance, it can diffuse around under the action of the centrifugal force generated by its own spiral state. Therefore, the water mist can be sprayed over a long distance and can also diffuse around during the spraying process, which is conducive to more contact between the water mist and the surrounding dust. In common technologies, the water mist is only ejected in the form of a straight light beam and will fall under the action of gravity due to insufficient power after reaching the designated position. Therefore, in common technologies, the diffusibility of the water mist is poor. However, in this application, by using the centrifugal force of the spiral water mist, the water mist can gradually diffuse around, greatly increasing the range of water mist dust suppression.

[0026] A plurality of discharge ports 211 communicating with the spiral mist discharge channel 271 are provided on the cavity wall of the spiral mist discharge channel 271. The function of the discharge ports 211 is to enable the water mist to be discharged outward at the position of the inner wall of the spiral channel. The discharged water mist has the power to move away from the flow control member 2 generated by the centrifugal force and the power to move in the spraying direction. Therefore, the water mist can be sprayed obliquely outward at the discharge ports 211, further increasing the range of water mist dust suppression.

[0027] The guiding member 4 is arranged at the discharge port 211, and the guiding member 4 is moved by an external driving force so that the guiding member 4 blocks or opens the discharge port 211. Among them, when the guiding member 4 opens the discharge port 211, a part of the guiding member 4 is located inside the spiral channel, and the guiding member 4 forms a guiding surface 41 obliquely arranged at the discharge port 211. At this time, the guiding surface 41 is inclined. Therefore, the forward power and the centrifugal power of the water mist will be better guided by the guiding surface 41 and discharged obliquely outward at the discharge port 211, and more kinetic energy of the water mist when it is discharged can be retained. The driving member 3 drives the movement of the guiding member 4, so that the discharge port 211 is opened and blocked. Therefore, this application has at least three usage methods: The first usage method is: the discharge port 211 is blocked, and at this time all the water mist is discharged in a spiral state.

[0028] The second usage method is: the discharge port 211 is opened. At this time, part of the water mist is discharged in a spiral state, and the other part of the water mist will be discharged obliquely outward outside the flow control member 2. Therefore, part of the water mist will normally diffuse around under the centrifugal force generated by the spiral state, and the other part of the water mist is directly sprayed around. The sprayed water mist will fall after the spraying power is exhausted. Therefore, the range of dust suppression will be larger.

[0029] The third method of use is to block the outlet of the spiral cavity and open the outlet 211. This can be used as an additional method of use.

[0030] The solution for the flow guide member 4 to open the outlet 211 can be that the axis of rotation of the flow guide member 4 is parallel or perpendicular to the axis of the flow control member 2 .

[0031] In one specific solution, the driving member 3 is a motor, and the flow guide member 4 is a plate. The driving member 3 drives the flow guide member 4 to rotate, so that the flow guide member 4 can be rotated to a position to block and open the outlet 211, thereby achieving the blocking and opening of the outlet 211.

[0032] In another specific solution, the guide member 4 is connected to the inner wall of the outlet 211 through a hinge 31, so that the guide member 4 is rotatably connected to the outlet 211. The driving member 3 is one of a cylinder, a hydraulic cylinder and an electric push rod 32, the output end of the driving member 3 is hinged to the guide member 4, and the cylinder body of the driving member 3 is hinged to the flow control member 2, so that the driving member 3 can drive the guide member 4 to rotate around the hinge 31 to achieve the blocking and opening of the outlet 211.

[0033] Specifically, the flow control member 2 further has an outer ring cavity 221 , and the outer ring cavity 221 is located outside the spiral demisting cavity 271 ; the spiral demisting cavity 271 and the outer ring cavity 221 are both connected to the air outlet 11 .

[0034] Among them, the first solution for the flow control component 2 to have an outer ring cavity 221 is: a sleeve 22 is arranged on the outside of the flow control component 2, the sleeve 22 is inserted into the flow control component 2, and a supporting frame 23 is arranged between the sleeve 22 and the outer wall of the flow control component 2, so that the sleeve 22 and the flow control component 2 are fixed, and the cavity between the sleeve 22 and the flow control component 2 is the outer ring cavity 221.

[0035] The second solution of the flow control member 2 having an outer ring cavity 221 is: a plurality of connecting pipes 24 are arranged outside the flow control member 2, and the plurality of connecting pipes 24 are uniformly surrounded outside the flow control member 2, and the cavities in the plurality of connecting pipes 24 together constitute the outer ring cavity 221. The connecting pipes 24 form an outer cavity. The connecting pipe 24 is connected to the air outlet 11 through a ring block, and the ring block 25 forms a connecting cavity, which is connected to the plurality of external cavities, so that the connecting cavity is connected to the air outlet 11. The connecting pipe 24 and the ring block are fixed to the flow control member 2.

[0036] The plurality of external cavities are arranged outside the spiral mist exhaust cavity 271 at intervals or in close proximity.

[0037] Since both the spiral mist exhaust channel 271 and the outer ring channel 221 are connected to the air outlet 11, part of the water mist is discharged outward through the spiral mist exhaust channel 271, and the other part of the water mist is discharged outward through the outer ring channel 221. In some cases, depending on the degree of spiral of the spiral mist exhaust channel 271, after the water mist is discharged from the spiral mist exhaust channel 271, the water mist will flow in a spiral state. Then, the power for the water mist to flow away from the spiral channel will be relatively reduced compared to directly discharging the water mist. Therefore, by using the outer ring channel 221 to directly discharge the water mist, the centrifugal water mist discharged from the spiral mist exhaust channel 271 can be diffused to the area of the water mist discharged from the outer ring channel 221 under the action of centrifugal force. Then, the water mist with centrifugal force will increase the power to move away from the spiral mist exhaust channel 271, enabling it to be transported farther. Thus, not only can it be diffused, but it can also be transported over a long distance for dust suppression, greatly increasing the dust suppression range. Additionally, in some cases, depending on the degree of spiral of the spiral mist exhaust channel 271, the water mist discharged from the spiral mist exhaust channel 271 will have a greater centrifugal force. Therefore, the water mist discharged from the outer ring channel 221 will be affected by the water mist discharged from the spiral mist exhaust channel 271 and spread more to the surroundings, having a larger dust suppression range. In some other cases, depending on the degree of spiral of the spiral mist exhaust channel 271, the spiral state of the water mist discharged from the spiral mist exhaust channel 271 is likely to be affected by the external air flow and disappear. As a result, the amplitude of spiral diffusion will decrease. For this reason, the water mist discharged from the annular channel can be used to wrap the water mist in a spiral state to prevent it from being affected by the external air flow, better ensure the annular state, better ensure the diffusion of the water mist, and increase the dust suppression range.

[0038] When the outer ring channel 221 is formed by a plurality of connecting pipes 24, the plurality of connecting pipes 24 can be closely attached to each other or can be spaced apart from each other.

[0039] Specifically, the flow control member 2 further has a circular channel 261, and the circular channel 261 is located in the middle of the spiral mist exhaust channel 271; both the spiral mist exhaust channel 271 and the circular channel 261 are connected to the air outlet 11.

[0040] Among them, the specific solution for the flow control member 2 to further have a circular channel 261 is to provide a fixed inner pipe in the flow control member 2. This inner pipe is fixed relative to the flow control member 2. The spiral mist exhaust channel 271 can be formed by a spiral plate 27. The inner pipe is fixed to the spiral plate 27, and the spiral plate 27 is fixed to the inner wall of the flow control member 2. The channel in the inner pipe is the circular channel 261.

[0041] In some cases, in order to enhance the effect of water mist dust removal, the water mist is charged. The charged water mist combines with the dust in the air, making it easier for the dust to aggregate and fall to the ground under the action of gravity. Therefore, in this application, a circular channel 261 is provided. The water mist discharged from the circular channel 261 will be in the middle of the spiral water mist, and since the water mist is charged, the spiral water mist will be subjected to the repulsive force between the charges, causing it to spread more to the surroundings.

[0042] In some embodiments regarding the discharge port 211, multiple discharge ports 211 may be provided, and the multiple discharge ports 211 are arranged along the extension trajectory of the spiral mist discharge channel 271. By driving an external force to move the guide member 4, some or all of the discharge ports 211 are blocked or opened. Preferably, the spiral mist discharge channel 271 has a front section, a middle section, and a rear section, and the discharge port 211 is located in the rear section. When the water mist has a preliminary spiral state, that is, when the water mist has centrifugal force, it can be discharged outward at the discharge port 211. Among them, the setting of the multiple discharge ports 211 further increases the range of water mist diffusion, and the arrangement of the multiple discharge ports 211 along the extension trajectory of the spiral mist discharge channel 271 can better enable the water mist with centrifugal force to retain its centrifugal force and be discharged outward at the discharge position.

[0043] In a specific solution, the guide member 4 is a plate body, and the guide member 4 is rotatably connected to the discharge port 211. The driving member 3 includes an electric push rod 32 and a connecting frame 33. The connecting frame 33 is hinged to multiple guide members 4, and the electric push rod 32 is connected to the connecting frame 33. Therefore, one electric push rod 32 drives multiple guide members 4 to rotate, and at the same time controls the opening of multiple discharge ports 211. In addition, multiple electric push rods 32 and multiple connecting frames 33 can also be provided, and each electric push rod 32 controls the rotation of some of the guide members 4 to achieve the simultaneous opening of some of the discharge ports 211.

[0044] In another specific solution, the driving member 3 includes an electric push rod 32, a connecting frame 33, and a connecting rope 34; the guide member 4 is a plate body, and a torsion spring 35 is provided at the position where the guide member 4 is rotatably connected to the discharge port 211. The torsion spring 35 will cause the guide member 4 to open the discharge port 211, that is, the guide member 4 will rotate towards the inside of the discharge port 211. Multiple connecting ropes 34 are provided, and the connecting ropes 34 connect the guide member 4 and the connecting frame 33. The electric push rod 32 drives the connecting frame 33 to move, and the connecting frame 33 pulls the guide member 4 through the connecting rope 34, causing the guide member 4 to rotate. In turn, the guide member 4 overcomes the torsion force of the torsion spring 35, causing the guide member 4 to block the discharge port 211. When the connecting frame 33 moves, the connecting rope 34 will also be loosened, and then the guide member 4 will open the discharge port 211 under the action of the torsion spring 35, thus realizing the opening and blocking of all the discharge ports 211. In addition, multiple driving members 3 and connecting frames 33 can also be provided to achieve the opening of some of the discharge ports 211.

[0045] In addition, the driving external force can also be provided manually. The flow guide member 4 rotates with the drain opening 211, and the operator rotates the flow guide member 4 manually to open all or part of the drain opening 211 with the flow guide member 4.

[0046] In some embodiments, the circular channel 261 and the outer ring channel 221 have a mist discharge outlet that extends at least partially obliquely away from the ground.

[0047] Among them, the first specific solution regarding the circular channel 261 having a mist discharge outlet that extends obliquely away from a point can be: a tapered flared opening 262 is formed at the outlet of the circular channel 261. Therefore, when the water mist is discharged outward through the circular channel 261, it will diffuse around at the position of the mist discharge outlet. And there are some positions of the tapered flared opening 262 that extend away from the ground. Among them, the purpose of the mist discharge outlet extending partially away from the ground is to enable the water mist discharged outward from the circular channel 261 to flow upward, so that it will carry the water mist discharged from the spiral mist discharge channel upward, allowing the water mist to flow in the air for a longer time before landing. Therefore, it can better increase the humidity in the air and better contact with dust, and perform dust reduction treatment. The solution for the outer ring channel 221 having a mist discharge outlet that extends partially away from the ground can also be achieved by forming a tapered flared opening 262.

[0048] Regarding a second specific example where the circular channel 261 has a mist discharge outlet that at least partially extends obliquely away from the ground, the flow control member 2 may include: a diversion pipe 21, a support frame 28, a spiral plate 27, and a plug rod 26. The middle part of the plug rod 26 forms the circular channel 261. The spiral plate 27 is fixed to the plug rod 26; the support frame 28 is fixed to the diversion pipe 21, and the plug rod 26 is connected to the support frame 28, so that the plug rod 26 can be fixed relative to the diversion pipe 21. The diversion pipe 21 is used to dock with the air outlet 11, so that the spiral mist discharge channel 271 in the diversion pipe 21 is docked with the air outlet 11. Among them, the spiral plate 27 and the inner wall of the diversion pipe 21 form the spiral mist discharge channel 271. Specifically, at the end of the plug rod 26 away from the threaded slot 281, there is a guiding protrusion 29, and the guiding protrusion 29 forms a first conical surface 291 on the outer wall of the plug rod 26 that extends away from the axis of the plug rod 26. Thus, the first conical surface 291 is a surface that guides the outlet of the spiral mist discharge channel 271 to converge. The circular channel 261 has a second conical surface 292 at the guiding protrusion 29 that extends away from the axis of the plug rod 26. Among them, the second conical surface 292 is used to make the circular channel 261 have a mist discharge outlet that at least partially extends obliquely away from the ground. Due to the existence of the guiding protrusion 29, the angle at which the second conical surface 292 is inclined away from the axis of the plug rod 26 can be larger. Therefore, the diffusion degree of the water mist discharged from the circular channel 261 is greater. At this time, due to the existence of the first conical surface 291, the water mist discharged from the spiral mist discharge channel 271 will be converged, and the spiral state of the discharged water mist can be better ensured.

[0049] Regarding a third specific solution where the circular channel 261 has a mist discharge outlet that at least partially extends obliquely away from the ground, a baffle 294 may be provided at the outlet of the circular channel 261. The baffle 294 has a third conical surface 293, and the third conical surface 293 is parallel to the second conical surface 292. Therefore, the water mist discharged from the circular channel 261 can be directly guided so that the water mist can be sprayed away from the ground. In addition, the lower part of the baffle 294 can be fixed to the lower part of the second conical surface 292. Therefore, the water mist discharged from the circular channel 261 can only be sprayed away from the ground.

[0050] Among some other specific solutions where the outer ring channel 221 has a mist discharge outlet that at least partially extends away from the ground, a solution similar to that of the circular channel 261 having a mist discharge outlet that at least partially extends away from the ground may also be adopted and will not be elaborated.

[0051] In some other embodiments, the flow control member 2 also includes a diversion pipe 21, a support frame 28, a spiral plate 27, and a plug rod 26. Among them, the support frame 28 has a threaded slot 281, and the plug rod 26 has a plug portion that matches the threaded slot 281. The plug rod 26 is inserted into the threaded slot 281 and is threadedly connected to the threaded slot 281. An elastic abutting portion 5 is provided on the inner wall of the spiral plate 27 or the diversion pipe 21 to make the spiral plate 27 abut tightly against the inner wall of the diversion pipe 21. The cooperation between the plug rod 26 and the threaded slot 281 is to detachably connect the plug rod 26 to the support frame 28, that is, the plug rod 26 is detachably connected to the diversion pipe 21. Therefore, the plug rod 26 and the spiral plate 27 can be removed outward in the spiral mist discharge channel 271. This facilitates the replacement of the spiral plate 27 with different spiral degrees and the cleaning of the spiral plate 27. The elastic abutting portion 5 can make the rubber pad adhered to the peripheral portion of the spiral plate 27, and the elastic abutting portion 5 can also make the rubber pad adhered to the inner wall of the diversion pipe 21. The elastic abutting portion 5 is provided to ensure that during the disassembly and assembly of the spiral plate 27 relative to the diversion pipe 21, the spiral plate 27 can abut tightly against the inner wall of the diversion pipe 21 and scrape off the dust and impurities on the inner wall of the diversion pipe 21, realizing the cleaning of the diversion pipe 21. In addition, it is also convenient for disassembly and assembly, and can ensure the sealing performance between the spiral pipe and the inner wall of the diversion pipe 21 after installation, better ensuring the spiral state of the water mist discharged from the spiral mist discharge channel 271.

[0052] In a specific solution, in order to make the plug rod 26 easier to be disassembled from the threaded slot 281, a protruding portion 6 for easy gripping is provided on the end face of the plug rod 26 facing away from the threaded slot 281.

[0053] In the first specific solution where the mist discharge outlet of the circular channel 261 extends obliquely away from a partial deviation point, the protruding portion 6 is directly provided at the end of the plug rod 26 facing away from the support frame 28.

[0054] In the second specific solution where the mist discharge outlet of the circular channel 261 extends obliquely away from a partial deviation point, the protruding portion 6 is located between the first conical surface 291 and the second conical surface 292, so that the distance between the protruding portion 6 and the axis of the plug rod 26 is greater than the distance between the outer wall of the plug portion and the axis of the plug rod 26. Thus, applying a force to the protruding portion 6 can play the role of a labor-saving lever.

[0055] In some other embodiments, the atomization device for civil engineering construction further includes a water mist diffusing member 7. The water mist diffusing member 7 is arranged at a preset position. When the mist ejector body 1 sprays water mist to the preset position, the water mist diffusing member 7 diffuses the water mist around.

[0056] One specific solution regarding the water mist diffusing member 7 is: The water mist diffuser 7 includes: a moving carrier 71 and a vortex fan 72 provided on the moving carrier 71. The moving carrier 71 is a vehicle body. The moving carrier 71 moves the vortex fan 72 to a preset position, and then after the fog injector sprays the water mist to the preset position, the vortex fan 72 will provide a wind force for the water mist to diffuse around. Therefore, the water mist can diffuse around, rather than the water mist falling downward under the action of gravity, and the water mist can be evenly distributed in the air. The preset position can be the position where the water mist ejected by the fog injector loses power and is about to fall downward. The vortex fan 72 adopts the prior art and has a structure with turbine blades and a motor. In addition, the vortex fan 72 will have an air outlet 11 for outputting air. The air outlet 11 is a fan-shaped opening, the air outlet 11 faces upward and the side, and the air outlet 11 does not face downward. Therefore, it is beneficial to improve the diffusion of the water mist and improve the dust reduction effect.

[0057] Another specific solution for the water mist diffuser 7 is: The water mist diffuser 7 includes a moving carrier 71 and a rod body with a negative charge provided on the moving carrier 71. The water mist preferably has a negative charge. Therefore, when the water mist moves to the rod body with a negative charge, the water mist will move away from the rod body with a negative charge due to the repulsion between the charges, thereby realizing the diffusion of the water mist. The rod body with a negative charge can be negatively charged through the negative electrode of an external power supply, or by friction or corona discharge.

[0058] In some other embodiments, the atomization device for civil engineering construction further includes a heating element, and the heating element is used to directly or indirectly heat the flow control member 2 so that the spiral mist discharge channel 271, the outer ring channel 221, and the circular channel 261 are heated; the temperatures of the spiral mist discharge channel 271, the outer ring channel 221, and the circular channel 261 are all higher than the temperature of the water mist.

[0059] In one solution, the heating element is a conductive coil, and the conductive coil is wound around the outside of the flow control member 2. When the conductive coil is energized, the flow control member 2 is made of a metal material. Therefore, the entire flow control member 2 can be heated. Both the spiral plate 27 and the insertion rod 26 are made of metal materials. The two spiral plates 27 are in contact with the inner wall of the flow control member 2, that is, the inner wall of the spiral mist discharge channel 271. Therefore, heat exchange between metals can heat the outer ring channel 221, the spiral mist discharge channel 271, and the circular channel 261 until the temperature is higher than the temperature of the water mist, thereby greatly reducing the situation where the water mist contacts the flow control member 2 and the water mist condenses into water droplets. Or in some solutions, the conductive coil is wound around the outer wall of the sleeve 22. Or a sandwich layer is formed on the wall of the flow control member 2, and the conductive coil is placed in this sandwich layer.

[0060] In another solution, the heating component adopts a water pump, water pipes, a water tank and heating wires. The heating wires heat the water in the water tank. The water pipes are wound around the sleeve 22 or the flow control member 2. The water pump circulates the water through the water pipes and the water tank. Therefore, heat exchange is carried out between the water and the flow control member 2, so that the outer ring channel 221, the spiral mist discharge channel 271 and the circular channel 261 are all heated until the temperature is higher than the temperature of the water mist, thereby greatly reducing the condensation of water mist into water droplets when the water mist contacts the flow control member 2.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
