Description

Technical Field

[0001] The present application relates to the field of atomization dust reduction, and in particular to an atomization device for civil engineering construction. Background Art

[0002] Currently, atomization devices used in civil engineering construction are used to reduce dust generated during construction. Common examples include fog cannons or sprayers. By spraying water mist particles, liquid mist dust reduction can effectively reduce pollutants and dust in the air, effectively alleviating smog.

[0003] In the related technology, the Chinese patent application number CN201910670945.7 proposes to use a drive component to adjust the angle of the air outlet of the hair duct at multiple angles, so that the water mist can be better distributed in more positions. However, the water mist is discharged outward in the form of dense water droplets, resulting in a constant area of water mist distribution per unit time. Multi-angle adjustment of the air outlet angle can only increase the water mist distribution area over a long period of time, but it is difficult to increase the water mist distribution area per unit time.

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

[0005] Regarding the related technologies mentioned above: Although incorporating the solution of this patent into the above patent document increases the water mist distribution area per unit time, it ultimately leads to a decrease in the water mist distribution area over a long period of time, making it difficult to take into account both the water mist spraying range and the area of rapid water mist distribution. Summary of the Invention

[0006] In order to improve the problem of difficulty in taking into account both the water mist spraying range and the area of rapid distribution of the water mist, the present application provides an atomization device for civil engineering construction.

[0007] The present application provides an atomizing device for civil engineering construction using the following technical solution:

[0009] By adopting the above technical solution, the water mist is discharged in a spiral state. The water mist itself will have centrifugal force. Then, after the water mist is discharged outward, it is better diffused in all directions under the action of centrifugal force, which increases the water mist's diffusion to a larger space in a short time and enhances the dust reduction effect of the water mist. The guide member allows the water mist to be ejected outward at an angle, and the water mist ejected outward at an angle makes the water mist in the spiral mist discharge cavity. Therefore, the water mist ejected outward at an angle also increases the power of the inclined ejection under the action of centrifugal force. The inclined range of the water mist is increased, which can further increase the speed of the water mist diffusion, thereby enhancing the dust reduction effect.

[0010] Optionally, the flow control member further has an outer ring cavity, which is located outside the spiral demisting cavity; the spiral demisting cavity and the outer ring cavity are both connected to the air outlet.

[0013] Optionally, the circular cavity and the outer ring cavity have a mist exhaust outlet that at least partially extends obliquely away from the ground.

[0014] Optionally, the atomization device for civil engineering construction further includes a water mist diffuser, which is disposed at a preset position. When the mist emitter sprays the water mist to the preset position, the water mist diffuser diffuses the water mist to all sides.

[0015] Optionally, the atomization device used for civil engineering construction also includes a heating element, which is used to directly or indirectly heat the flow control element to increase the temperature of the spiral demisting cavity, the outer ring cavity and the circular cavity; the temperatures of the spiral demisting cavity, the outer ring cavity and the circular cavity are all higher than the temperature of the water mist.

[0016] Optionally, the flow control component includes: a guide tube, a support frame, a spiral plate and an insertion rod; the insertion rod forms the circular cavity; the spiral plate is fixed to the insertion rod; the support frame is fixed to the guide tube, and the support frame has a threaded slot, the insertion rod has an insertion portion matching the threaded slot, the insertion rod is inserted into the threaded slot and threadedly connected to the threaded slot; the spiral plate or the inner wall of the guide tube has an elastic abutment portion that presses the spiral plate against the inner wall of the guide tube.

[0017] Optionally, the end surface of the insertion rod facing away from the threaded slot has a protrusion for easy gripping; the end of the insertion rod facing away from the threaded slot has a guide protrusion, and the guide protrusion forms a first conical surface on the outer wall of the insertion rod extending away from the axis of the insertion rod; the circular cavity has a second conical surface at the guide protrusion extending away from the axis of the insertion rod; the protrusion is located between the first conical surface and the second conical surface, so that the distance between the protrusion and the axis of the insertion rod is greater than the distance between the outer wall of the insertion part and the axis of the insertion rod.

[0018] Optionally, the outer ring cavity includes multiple external cavities and a connecting cavity connected to the multiple external cavities; the connecting cavity is connected to the air outlet; and the multiple external cavities are arranged at intervals or close to each other outside the spiral demisting cavity.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. By setting a discharge port on the spiral mist discharge cavity of the flow control component, the water mist can be discharged outward at the discharge port, thereby ensuring the outward spray distance of the water mist. In the process of outward spraying of the water mist, the spiral mist discharge cavity is used to increase the water mist distribution area per unit time, and the discharge port is used to increase the water mist spray distance and the distribution area of the water mist over a long period of time;

[0021] 2. The spray distance of the water mist can be further increased by setting the outer ring cavity and the circular cavity;

[0022] 3. Through the setting of the outer ring cavity, the water mist of the outer ring cavity will overlap with the water mist of the spiral cavity, which can increase the spray distance of the water mist discharged outward from the spiral mist exhaust cavity. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The following is combined with Figure 1-15 This application is described in further detail.

[0047] The embodiment of the present application discloses an atomizing device for civil engineering construction.

[0048] An atomizing device for civil engineering construction comprises: a sprayer body 1, a flow control member 2, a driving member 3 and a flow guide member 4. The driving member 3 is used to provide an external driving force.

[0049] The main body 1 of the mist emitter has at least an air outlet 11 for high-speed air discharge and a water outlet 12 located around the air outlet 11. The mist emitter 1 utilizes existing technology, using a fan to generate a flowing airflow, which then emits water mist. The flowing airflow drives the water mist, achieving long-range spraying and thus achieving widespread dust reduction. In some other solutions, the mist emitter 1 is also called a mist cannon.

[0050] The flow control element 2 has at least a spiral mist discharge cavity 271 that is connected to the air outlet 11 so that the water mist is discharged in a spiral flow state. In this embodiment, the flow control element 2 adopts a tube body, and the spiral mist discharge cavity 271 is formed by arranging a spiral tube or a spiral plate 27 in the tube body. After the water mist passes through the spiral mist discharge cavity 271, the water mist will have a spiral state. Therefore, when the water mist is sprayed to a distance, it can spread to the surroundings under the action of the centrifugal force generated by its own spiral state. Therefore, the water mist can be sprayed from a long distance or spread to the surroundings during the spraying process, which is conducive to allowing the water mist to come into contact with more surrounding dust. In common technologies, the water mist is only emitted in the form of a straight beam of light. After the water mist reaches the designated position, it will fall under the action of gravity due to insufficient power. Therefore, in common technologies, the diffusivity of the water mist is poor. The present application utilizes the centrifugal force of the water mist spiral to make the water mist gradually spread to the surroundings, greatly increasing the range of water mist dust reduction.

[0051] The cavity wall of the spiral mist exhaust cavity 271 is provided with a plurality of discharge ports 211 connected to the spiral mist exhaust cavity 271. The function of the discharge ports 211 is to enable the water mist to be discharged outward at the inner wall of the spiral cavity. The discharged water mist has the power generated by centrifugal force to move away from the flow control component 2 and the power to move in the injection direction. Therefore, the water mist can be sprayed outward at an angle at the discharge port 211, further increasing the range of water mist dust reduction.

[0052] The guide member 4 is arranged at the outlet 211, and the guide member 4 is moved by driving an external force so that the guide member 4 blocks or opens the outlet 211. When the guide member 4 opens the outlet 211, part of the guide member 4 is located in the spiral cavity, and the guide member 4 forms a guide surface 41 obliquely disposed at the outlet 211. At this time, the guide surface 41 is inclined, so the forward power and centrifugal power of the water mist will be better discharged obliquely outward at the outlet 211 under the guidance of the guide surface 41, and more kinetic energy of the water mist can be retained when it is discharged. The driving member 3 drives the movement of the guide member 4 to open and block the outlet 211. Therefore, the present application has at least three methods of use:

[0053] The first method of use is: the outlet 211 is blocked, and all the water mist is discharged in a spiral state.

[0054] The second method of use is: the discharge port 211 is opened, at this time part of the water mist is discharged in a spiral state, and another part of the water mist is discharged outward at an angle outside the flow control component 2, so that part of the water mist will normally spread to the surroundings by the centrifugal force generated by the spiral state, and another part of the water mist is directly sprayed to the surroundings. After the spraying power is exhausted, the sprayed part of the water mist will fall, thereby making the dust reduction range larger.

[0055] 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.

[0056] 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 to or perpendicular to the axis of the flow control member 2 .

[0057] In one specific solution, the driving member 3 is a motor and the guide member 4 is a plate. The driving member 3 drives the guide member 4 to rotate, so that the 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.

[0058] In another specific embodiment, the flow guide 4 is connected to the inner wall of the outlet 211 via a hinge 31, thereby enabling rotational connection between the flow guide 4 and the outlet 211. The driving member 3 is a pneumatic cylinder, a hydraulic cylinder, or an electric push rod 32. The output end of the driving member 3 is hingedly connected to the flow guide 4, and the cylinder of the driving member 3 is hingedly connected to the flow control member 2. Therefore, the driving member 3 can drive the flow guide 4 to rotate about the hinge 31 to achieve the sealing and opening of the outlet 211.

[0059] Specifically, the flow control element 2 further has an outer ring cavity 221 , which 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 .

[0060] Among them, the first solution for the flow control member 2 to have an outer ring cavity 221 is: a sleeve 22 is set on the outside of the flow control member 2, the sleeve 22 is inserted into the flow control member 2, and a supporting frame 23 is set between the sleeve 22 and the outer wall of the flow control member 2, so that the sleeve 22 and the flow control member 2 are fixed, and the cavity between the sleeve 22 and the flow control member 2 is the outer ring cavity 221.

[0061] A second embodiment of the flow control element 2 having an outer annular cavity 221 includes multiple connecting tubes 24 disposed on the exterior of the flow control element 2. These connecting tubes 24 are evenly arranged around the exterior of the flow control element 2, and the cavities within these connecting tubes 24 collectively form the outer annular cavity 221. The connecting tubes 24 form the outer cavity. The connecting tubes 24 connect to the air outlet 11 via a ring block. The ring block 25 forms a connecting cavity, which communicates with the multiple outer cavities, allowing the connecting cavity to connect to the air outlet 11. Both the connecting tubes 24 and the ring block are fixed to the flow control element 2.

[0062] The plurality of external cavities are arranged outside the spiral mist exhaust cavity 271 at intervals or in close proximity.

[0063] Since the spiral mist exhaust cavity 271 and the outer ring cavity 221 are both connected to the air outlet 11, part of the water mist is discharged outwards in the spiral mist exhaust cavity 271, and the other part of the water mist is discharged outwards in the outer ring cavity 221. In some cases, depending on the degree of spirality of the spiral mist exhaust cavity 271, the water mist will flow in a spiral state after being discharged from the spiral mist exhaust cavity 271, and the power of the water mist to flow away from the spiral cavity will be relatively reduced compared to directly discharging the water mist. Therefore, by using the outer ring cavity 221 to discharge the water mist directly, the water mist with centrifugal force discharged outwards from the spiral mist exhaust cavity 271 can be diffused to the area of the water mist discharged from the outer ring cavity 221 by the centrifugal force, and then the water mist with centrifugal force will increase the power to move away from the spiral mist exhaust cavity 271, so that it can be transported farther, so that it can not only be diffused, but also can be transported over long distances for dust reduction, greatly increasing the range of dust reduction. In addition, in some cases, depending on the degree of spiraling of the spiral mist exhaust cavity 271, the water mist discharged from the spiral mist exhaust cavity 271 will have a greater centrifugal force. Therefore, the water mist discharged from the outer ring cavity 221 will be affected by the water mist discharged from the spiral mist exhaust cavity 271, and will spread more to the surroundings, thereby having a larger dust reduction range. In some other cases, depending on the degree of spiraling of the spiral mist exhaust cavity 271, the spiral state of the water mist discharged from the spiral mist exhaust cavity 271 will be easily affected by the external airflow and disappear, thereby reducing the amplitude of the spiral diffusion. For this reason, the water mist discharged from the annular cavity can be wrapped around the outside of the spiral state water mist to prevent it from being affected by the external airflow, better ensure the annular state, better ensure the diffusion of the water mist, and increase the range of dust reduction.

[0064] When the outer annular cavity 221 is formed by a plurality of connecting tubes 24 , the plurality of connecting tubes 24 may be closely fitted together or spaced apart from each other.

[0065] Specifically, the flow control member 2 further has a circular cavity 261 , and the circular cavity 261 is located in the middle of the spiral demisting cavity 271 ; the spiral demisting cavity 271 and the circular cavity 261 are both connected to the air outlet 11 .

[0066] The flow control element 2 further includes a circular cavity 261. Specifically, a fixed inner tube is provided in the flow control element 2. The inner tube is fixed relative to the flow control element 2. A spiral plate 27 is used to form a spiral mist discharge cavity 271. The inner tube is fixed to the spiral plate 27, which is in turn fixed to the inner wall of the flow control element 2. The cavity in the inner tube is the circular cavity 261.

[0067] In some cases, to enhance the effectiveness of water mist dust removal, the water mist is charged. The charged water mist combines with dust in the air, causing the dust to gather more easily and fall to the ground under the action of gravity. Therefore, the present application provides a circular cavity 261. The water mist discharged through the circular cavity 261 will be in the middle of the spiral state of water mist. Since the water mist is charged, the spiral state of water mist will be affected by the repulsive force between the charges, causing it to spread more to the surrounding area.

[0068] In some embodiments of the discharge port 211, a plurality of discharge ports 211 may be provided, and the plurality of discharge ports 211 are provided along the extension trajectory of the spiral demisting cavity 271. The guide member 4 is driven by an external force to move, so that part or all of the discharge ports 211 are blocked or opened. Preferably, the spiral demisting cavity 271 has a front section, a middle section and a rear section, and the discharge port 211 is located in the rear section, so that the water mist can be discharged outward at the discharge port 211 when the water mist has a preliminary spiral state, that is, when the water mist has centrifugal force. Among them, the provision of a plurality of discharge ports 211 further increases the range of water mist diffusion, and the provision of a plurality of discharge ports 211 along the extension trajectory of the spiral demisting cavity 271 can better enable the water mist with centrifugal force to retain its own centrifugal force and be discharged outward at the discharge position.

[0069] In one specific embodiment, the deflector 4 is a plate, rotatably connected to the outlet 211. The driving member 3 includes an electric push rod 32 and a connecting frame 33. The connecting frame 33 is hingedly connected to multiple deflectors 4. The electric push rod 32 and the connecting frame 33 enable a single electric push rod 32 to rotate multiple deflectors 4, thereby simultaneously controlling the opening of multiple outlets 211. Alternatively, multiple electric push rods 32 and multiple connecting frames 33 may be provided, with each electric push rod 32 controlling the rotation of a portion of the deflectors 4, thereby simultaneously controlling the opening of a portion of the outlets 211.

[0070] In another specific embodiment, the driving member 3 includes an electric push rod 32, a connecting frame 33, and a connecting rope 34. The deflector 4 is a plate. A torsion spring 35 is provided at the location where the deflector 4 is rotatably connected to the outlet 211. The torsion spring 35 causes the deflector 4 to open the outlet 211, that is, to rotate the deflector 4 toward the inside of the outlet 211. Multiple connecting ropes 34 are provided, connecting the deflector 4 to the connecting frame 33. The electric push rod 32 drives the connecting frame 33 to move. The connecting frame 33 pulls the deflector 4 via the connecting rope 34, causing the deflector 4 to rotate. In turn, the deflector 4 overcomes the torsion force of the torsion spring 35, causing it to block the outlet 211. The movement of the connecting frame 33 also loosens the connecting rope 34. Subsequently, the deflector 4 opens the outlet 211 under the action of the torsion spring 35, thereby opening and blocking all outlets 211. Alternatively, multiple driving members 3 and connecting frames 33 may be provided to partially open the outlet 211.

[0071] In addition, the driving external force can also be provided manually, and the guide member 4 and the outlet 211 rotate, and the guide member 4 is rotated manually to realize that all or part of the guide member 4 opens the outlet 211.

[0072] In some embodiments, the circular cavity 261 and the outer ring cavity 221 have mist exhaust outlets that at least partially extend obliquely away from the ground.

[0073] Among them, the first specific solution for the circular cavity 261 having a mist outlet that partially extends away from the point can be: a conical flare 262 is opened at the outlet of the circular cavity 261, so that when the water mist is discharged outward through the circular cavity 261, it will be diffused and discharged in all directions at the position of the mist outlet. The conical flare 262 will have a portion extending away from the ground. The purpose of the mist outlet partially extending away from the ground is to enable the water mist discharged from the circular cavity 261 to flow upward, thereby entraining the water mist discharged from the spiral mist outlet to flow upward, so that the water mist can flow in the air for a longer time before landing, thereby better increasing the humidity in the air and better contacting with dust, and performing dust reduction treatment. Among them, the solution for the outer ring cavity 221 having a mist outlet that partially extends away from the ground can also be achieved by opening a conical flare 262.

[0074] Regarding the second specific embodiment in which the circular cavity 261 has a demisting outlet that at least partially extends obliquely away from the ground, the flow control part 2 may include: a guide tube 21, a support frame 28, a spiral plate 27 and an insertion rod 26. The middle part of the insertion rod 26 forms the circular cavity 261. The spiral plate 27 is fixed to the insertion rod 26; the support frame 28 is fixed to the guide tube 21, and the insertion rod 26 is connected to the support frame 28, so that the insertion rod 26 can be fixed relative to the guide tube 21. The guide tube 21 is used to dock with the air outlet 11, so that the spiral demisting cavity 271 in the guide tube 21 docks with the air outlet 11. Among them, the spiral plate 27 and the inner wall of the guide tube 21 form the spiral demisting cavity 271. Specifically, the end of the rod 26 facing away from the threaded slot 281 includes a guide protrusion 29. This guide protrusion 29 forms a first tapered surface 291 on the outer wall of the rod 26, extending away from the axis of the rod 26. This first tapered surface 291 acts as a guiding surface for converging the outlet of the spiral mist exhaust channel 271. The circular channel 261 also includes a second tapered surface 292 extending away from the axis of the rod 26 at the guide protrusion 29. This second tapered surface 292 is designed to provide a mist exhaust outlet that extends at least partially away from the ground. The presence of the guide protrusion 29 allows the second tapered surface 292 to be tilted away from the axis of the rod 26 at a greater angle, thereby increasing the diffusion of the mist discharged from the circular channel 261. The presence of the first tapered surface 291 also converges the mist discharged from the spiral mist exhaust channel 271, thereby better ensuring the spiral shape of the mist.

[0075] A third specific solution for providing circular cavity 261 with a mist outlet that extends at least partially obliquely away from the ground can include providing a baffle 294 at the outlet of circular cavity 261. Baffle 294 has a third tapered surface 293 that is parallel to second tapered surface 292. This allows the mist discharged from circular cavity 261 to be directly directed and ejected away from the ground. Furthermore, the lower portion of baffle 294 can be fixed to the lower portion of second tapered surface 292, thereby allowing the mist discharged from circular cavity 261 to be ejected only away from the ground.

[0076] Among them, in some other specific solutions in which the outer ring cavity 221 has a mist outlet partially extending away from the ground, a solution similar to that in which the circular cavity 261 has a mist outlet partially extending away from the ground can also be adopted, which will not be elaborated.

[0077] In some other embodiments, the flow control component 2 also includes: a guide tube 21, a support frame 28, a spiral plate 27 and an insert rod 26. The support frame 28 has a threaded slot 281, and the insert rod 26 has an insert portion that matches the threaded slot 281. The insert rod 26 is inserted into the threaded slot 281 and is threadedly connected to the threaded slot 281. The spiral plate 27 or the inner wall of the guide tube 21 has an elastic abutment portion 5 that presses the spiral plate 27 against the inner wall of the guide tube 21. The cooperation between the insert rod 26 and the threaded slot 281 is to make the insert rod 26 detachable from the support frame 28, that is, the insert rod 26 is detachably connected to the guide tube 21, so that the insert rod 26 and the spiral plate 27 can be removed outward in the spiral demisting cavity 271. It is convenient to replace spiral plates 27 with different spiral degrees and to clean the spiral plates 27. The elastic abutment 5 can be a rubber pad adhered to the periphery of the spiral plate 27, or it can be a rubber pad adhered to the inner wall of the flow guide tube 21. The elastic abutment 5 is provided so that during assembly and disassembly of the spiral plate 27 relative to the flow guide tube 21, the spiral plate 27 can abut against the inner wall of the flow guide tube 21, scraping away dust and impurities on the inner wall of the flow guide tube 21, thereby cleaning the flow guide tube 21. This also facilitates assembly and disassembly, and after installation, ensures a tight seal between the spiral tube and the inner wall of the flow guide tube 21, thereby better ensuring the spiral state of the mist discharged from the spiral mist discharge channel 271.

[0078] In a specific solution, in order to make it easier to remove the insertion rod 26 from the threaded slot 281 , a protrusion 6 that is easy to hold is provided on the end surface of the insertion rod 26 away from the threaded slot 281 .

[0079] In the first specific solution in which the circular cavity 261 has a mist outlet partially extending obliquely away from the point, the protrusion 6 is directly provided at the end of the insertion rod 26 away from the support frame 28 .

[0080] In the second embodiment in which the circular cavity 261 has a mist outlet that extends partially away from the point of inclination, the protrusion 6 is located between the first tapered surface 291 and the second tapered surface 292, such that the distance between the protrusion 6 and the axis of the insertion rod 26 is greater than the distance between the outer wall of the insertion portion and the axis of the insertion rod 26. Thus, applying force to the protrusion 6 can function as a force-saving lever.

[0081] In some other embodiments, the atomizing device for civil engineering construction further includes a water mist diffuser 7, which is arranged at a preset position. When the mist emitter body 1 sprays water mist to the preset position, the water mist diffuser 7 diffuses the water mist to the surroundings.

[0082] One specific solution for the water mist diffuser 7 is:

[0083] The water mist diffuser 7 includes: a mobile carrier 71 and a vortex fan 72 arranged on the mobile carrier 71. The mobile carrier 71 adopts a vehicle body. The mobile carrier 71 moves the vortex fan 72 to a preset position. Then, after the mist sprayer sprays the water mist to the preset position, the vortex fan 72 will provide wind force for the water mist to spread in all directions, so that the water mist can be spread in all directions, rather than the water mist falling downward under the action of gravity, so that the water mist can be evenly distributed in the air. The preset position can make the water mist sprayed by the mist sprayer lose power and is about to fall downward. The vortex fan 72 adopts existing technology and is 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 outlet. The air outlet 11 faces upward and to the side, and the air outlet 11 does not face downward, so it is conducive to improving the diffusion of water mist and improving the dust reduction effect.

[0084] Another specific solution for the water mist diffuser 7 is:

[0085] The mist diffuser 7 includes a mobile carrier 71 and a negatively charged rod mounted on the carrier 71. The mist preferably carries a negative charge. Therefore, when the mist moves to the negatively charged rod, the repulsive force between the charges causes the mist to move away from the negatively charged rod, thereby achieving mist diffusion. The negatively charged rod can be negatively charged by connecting to a negative electrode of an external power source, by friction, or by corona discharge.

[0086] In some other embodiments, the atomization device for civil engineering construction further includes a heating element, which is used to directly or indirectly heat the flow control element 2 to increase the temperature of the spiral demisting cavity 271, the outer ring cavity 221 and the circular cavity 261; the temperatures of the spiral demisting cavity 271, the outer ring cavity 221 and the circular cavity 261 are all higher than the temperature of the water mist.

[0087] In one of the schemes, the heating element is a conductive coil, which is wound around the outside of the flow control element 2. The conductive coil is energized, and the flow control element 2 is made of metal material, so the flow control element 2 as a whole can be heated up. The spiral plate 27 and the plug 26 are both made of metal material. The two spiral plates 27 are in contact with the inner wall of the flow control element 2, that is, the inner wall of the spiral demisting cavity 271. Therefore, the heat exchange between the metals can make the outer ring cavity 221, the spiral demisting cavity 271 and the circular cavity 261 all heat up until the temperature is higher than the temperature of the water mist, thereby greatly reducing the situation where the water mist condenses into water droplets when it contacts the flow control element 2. Or in some schemes, the conductive coil is wound around the outer wall of the sleeve 22. Or a sandwich is formed on the wall of the flow control element 2, and the conductive coil is placed in the sandwich.

[0088] In another solution, the heating element adopts a water pump, a water pipe, a water tank and an electric heating wire. The electric heating wire heats the water in the water tank. The water pipe is wrapped around the sleeve 22 or the outside of the flow control element 2. The water pump circulates the water through the water pipe and the water tank. Therefore, heat exchange is carried out between the water and the flow control element 2 to achieve the outer ring cavity 221, the spiral mist discharge cavity 271 and the circular cavity 261 to heat up until the temperature is higher than the temperature of the water mist, thereby greatly reducing the situation where the water mist condenses into water droplets when it contacts the flow control element 2.

[0089] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
