Description

Technical Field

[0001] This invention belongs to the field of air treatment equipment, specifically relating to a water-carrier negative ion generator. Background Technology

[0002] Traditional negative ion generators are typically externally mounted in air purifiers, such as at the outlet of the air supply mechanism or at the end of the air supply duct, carrying negative ions into the target area via airflow. However, this design has certain drawbacks: First, negative ions rapidly attenuate during long-distance transmission due to collisions with positive ions and particulate matter in the air, resulting in a 30%-50% decrease in effective concentration, especially in high-speed airflows (>5 m / s), where diffusion efficiency is further reduced. Second, external generators require additional ionization chambers and airflow guiding structures, leading to increased device size and energy consumption.

[0003] Based on the above problems, there are currently technical solutions that combine air negative ions and water mist to increase the delivery distance by utilizing the quality of water mist, but the delivery distance is still limited in most cases.

[0004] For example, prior art 1, "CN208316022U A Hydrated Negative Oxygen Ion Generating Device," discloses a hydrated negative oxygen ion generating device. Its purpose is to generate hydrated negative oxygen ions and extend their propagation distance. The airflow is positioned within a gap, and a convex ring is provided at the rear edge of the third body to agitate the airflow. This convex ring can agitate the airflow when oxygen ions flow out, helping to further mix the insufficiently mixed negative ions with water vapor and oxygen in the ion generating chamber, forming hydrated negative oxygen ions. In this scheme, the negative ions, water vapor, and oxygen are first mixed within the ion generating chamber. Then, the negative pressure generated by the gap draws them into the gap through the through-hole, and finally, they flow from the gap outlet through the convex ring back into the ion generating chamber for further mixing. This multiple mixing of negative ions with water vapor and oxygen results in a good mixing effect. However, because the third body is the outer wall of the gap and is also on the airflow path, it creates significant air resistance, severely affecting the transport distance. In addition, this setting will cause the negative ion emitter to come into contact with water vapor, which will seriously affect the service life of the ion emitter.

[0005] In addition, the current water supply structure generally adopts an upper-mounted water tank, which makes the center of gravity of the device unreasonable and cannot recover condensate, resulting in water waste. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a water carrier negative ion generator that can provide long-distance water carrier negative ion delivery and save water resources.

[0007] This invention provides a water-carrier negative ion generating device, comprising a water-carrier negative ion generating structure and a water supply device; the water-carrier negative ion generating structure generates air negative ion airflow and water mist respectively through internal and external airflow channels, and guides the water mist to flow in the same direction and mixes it before outputting water-carrier negative ions through the ejection effect of the air negative ion airflow; the water supply device supplies water to the water-carrier negative ion generating structure by storing water below the water-carrier negative ion generating structure, recovering condensate water, and transferring water above the water-carrier negative ion generating structure.

[0008] The beneficial effects of this invention are as follows: The water-carrier negative ion generator provided by this invention utilizes internal and external airflow channels to generate air negative ion airflow and water mist respectively. Through the entrainment effect of the air negative ion airflow, the water mist is guided to flow in the same direction and mixed before being output as water-carrier negative ions. This has the following effects: 1. By utilizing the structural arrangement of the internal airflow channel, the induced annular external airflow channel, and the mixing chamber, the output distance and negative ion content of negative ions are significantly improved while maintaining a compact structure. 2. Due to the design of the internal and external channels, the water mist can be isolated from the negative ion generator in the air negative ion generator 2. Combined with the delivery direction of the internal air negative ion airflow in the internal airflow channel, water mist can be completely prevented from entering the internal airflow channel and affecting the service life of the negative ion generator, solving the problem of traditional negative ion generators being easily damaged by moisture. III. The air negative ion generator forms an internal air negative ion airflow within the internal airflow channel. This airflow serves both as the power source for outputting water-carrier negative ions and as the ejector to drive the water mist flow within the annular external airflow channel. This eliminates the need for a separate driving element for the water mist flow, reducing structural complexity and improving the utilization rate of the air supply mechanism in section 2 of the air negative ion generator. IV. The output of water-carrier negative ions contains water molecules, which can purify the water. Furthermore, the ambient humidity can be controlled by adjusting the amount of water mist.

[0009] The water supply device employs a structure where water is stored below the water carrier negative ion generating structure, condensate is recovered, and water is transferred from above the structure to supply water to the water carrier negative ion generating structure. This structure offers the following advantages: 1. It creates a closed-loop water circulation system, significantly improving water saving rates and reducing condensate loss compared to traditional open water supply systems. 2. By using bottom-to-bottom water storage and condensate recovery, the lower part of the water carrier negative ion generating device serves as the main water storage structure, while the upper part retains only a small-capacity water supply structure. This allows for a low center of gravity arrangement of the water carrier negative ion generating device, improving its layout stability. 3. When the water mist excitation device in the water carrier negative ion generating structure uses a water guide component for water supply, the small-volume water supply mechanism avoids excessive water storage, which could lead to excessive water pressure and an excessive amount of water entering the water guide component. This ensures that the water guide component and the water mist excitation device can absorb water evenly, resulting in more stable water mist generation. Attached Figure Description

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0013] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0014] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0015] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection, an electrical connection, a physical connection, or a wireless communication connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two elements or the interaction between two elements, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0016] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0017] As attached Figure 1 - Appendix Figure 18 As shown, the present invention provides a water-carrier negative ion generating device, including a water-carrier negative ion generating structure and a water supply device 301; The water-carrier negative ion generating structure uses internal and external airflow channels to generate air negative ion airflow and water mist respectively. Through the entrainment effect of the air negative ion airflow, the water mist is guided to flow in the same direction and mixed before being output as water-carrier negative ions. In specific operation, an internal air negative ion airflow is formed within the internal airflow channel 201, generating an entrainment effect. This internal air negative ion airflow acts as the entrainer, attracting the water mist within the annular external airflow channel 5 as the attracted stream. The internal air negative ion airflow causes the water mist within the annular external airflow channel 5 to flow with the internal air negative ion airflow and complete gas-liquid mixing within the mixing chamber 4. After gas-liquid mixing, water-carrier negative ions are formed (see attached diagram). Figure 6 The water-carrier negative ion output port 701 features alternating solid and hollow solid arrows and outputs negative ions. The water-carrier negative ions combine negative ions from the internal airflow and water mist, resulting in a higher negative ion content. Furthermore, because the negative ions are carried or propelled by water molecules, the output distance and suspension time are significantly improved. The gas-liquid mixing within the mixing chamber 4 increases the negative ion content of the output water-carrier negative ions and prevents localized aggregation of negative ions, ensuring uniform negative ion distribution in the output airflow.

[0018] The water supply device 301 supplies water to the water carrier negative ion generating structure by storing water below it, recovering condensate, and transferring water from above it. This arrangement creates a closed-loop water circulation system, significantly improving water saving and reducing condensation loss compared to traditional open water supply systems. Furthermore, the bottom-to-bottom water storage and condensate recovery allows the main water storage structure (main water tank 3013) to be located below the water carrier negative ion generating device, while only a small-capacity water supply structure (auxiliary water tank 3011) is retained above. This low center of gravity arrangement of the water carrier negative ion generating device improves its layout stability. Meanwhile, when the water mist generating device 302 in the water carrier negative ion generating structure uses the water guide 3012 (cotton swab) to supply water, the water supply structure with a small water storage capacity can avoid the water storage capacity being too large, which would lead to excessive water pressure and excessive water entering the water guide 3012. This can ensure that the water guide 3012 and the water mist generating device 302 can absorb water evenly, and can ensure that the generation of water mist is more stable.

[0019] The water-carrier negative ion generator provided by this invention generates air negative ion airflow and water mist respectively through internal and external airflow channels. The air negative ion airflow guides the water mist to flow in the same direction and mixes with it before outputting water-carrier negative ions, achieving the following effects: I. By utilizing the internal airflow channel 201, the annular external airflow channel 5, and the mixing chamber 4, the output distance and negative ion content are significantly improved while maintaining a compact structure.

[0020] Second, due to the design of the inner and outer ducts, the water mist can be isolated from the negative ion generator 202 in the air negative ion generator 2. Combined with the delivery direction of the inner air negative ion airflow in the inner airflow channel 201, the water mist can be completely prevented from entering the inner airflow channel 201 and affecting the service life of the negative ion generator 202, thus solving the problem that the traditional negative ion generator 202 is prone to moisture damage.

[0021] Third, the air negative ion generator forms an internal air negative ion airflow in the internal airflow channel 201, which serves as both the output power source for water carrier negative ions and the ejector to drive the water mist in the annular external airflow channel 5 to flow. This eliminates the need for an independent driving element for the water mist flow, reduces structural complexity, and improves the utilization rate of the air supply mechanism 203 in the air negative ion generator.

[0022] Fourth, the output of negative ions carried by the water carrier contains water molecules, which can purify the water molecules and control the ambient humidity by adjusting the amount of water mist.

[0023] The water supply device 301 supplies water to the water carrier negative ion generating structure by storing water below the structure, recovering condensate, and transferring water above the structure. This structure has the following advantages: First, it can form a closed-loop water circulation system for water storage, water supply, and condensate, which significantly improves water saving rate and reduces condensate loss compared to traditional open water supply systems.

[0024] Second, by adopting bottom-to-bottom water storage and condensate recovery, the bottom of the water carrier negative ion generator can be the main water storage structure (main water tank 3013), while only the water supply structure with a small water storage capacity (auxiliary water tank 3011) is retained above. This allows for a low center of gravity arrangement of the water carrier negative ion generator, improving the layout stability of the water carrier negative ion generator.

[0025] Third, when the water mist generating device 302 in the water carrier negative ion generating structure uses the water guide 3012 (cotton swab) to supply water, the small volume of the water supply mechanism can avoid excessive water storage, which would lead to excessive water pressure and excessive water volume entering the water guide 3012. This ensures that the water guide 3012 and the water mist generating device 302 can absorb water evenly, and can ensure that the generation of water mist is more stable.

[0026] In one embodiment, reference is made to the appendix. Figure 4 - Appendix Figure 12 The water-carrier negative ion generating structure includes a shell 1, an air negative ion generating device 2, and a water mist generating device 3. The shell 1 has a mixing chamber 4 and an opening 102 communicating with the mixing chamber 4. The air negative ion airflow generated by the air negative ion generating device 2 and the water mist generated by the water mist generating device 3 mix in the mixing chamber 4 and are output from the opening 102. The mixing chamber 4 is used to mix the air negative ion airflow and the water mist to increase the amount of negative ions in the water mist, while the opening 102 is used for outputting water-carrier negative ions, or for installing a guide 7 with a water-carrier negative ion output port 701. In this embodiment, the shell 1 has an inner cavity 101 and an opening 102 communicating with the inner cavity 101. The air negative ions and water mist output by the air negative ion generating device 2 and the water mist generating device 3 first act within the inner cavity 101 and are then output to the target location through the opening 102. In this embodiment, the water-carrier negative ion generating structure integrates the air negative ion generating device 2 and the water mist generating device 3 into a single, compact structure within the housing 1. This facilitates the assembly and maintenance of the water-carrier negative ion generating structure.

[0027] In one embodiment, the water mist generating device 3 includes a water mist activation device 302; the water mist activation device 302 is the output component of the water mist generating device 3, used to generate water mist; specifically, the water mist activation device 302 includes a vibrating plate and micropores disposed on the vibrating plate. Preferably, according to experiments, the pore size of the micropores is 1.6μm-2μm, which can reduce the water retention rate at the outlet of the water carrier negative ion output port 701. At this time, the water consumption is 0.12g / min, reducing the water consumption rate, saving water resources, and reducing the frequency of water addition. The water supply device 301 includes a main water tank 3013, a water pump 3014, and a secondary water tank 3011. The main water tank 3013 is arranged below the mixing chamber 4 and is used to form a water storage below the water carrier negative ion generating structure. The top of the main water tank 3013 is connected to the bottom of the mixing chamber 4, thereby realizing the recovery of condensate in the mixing chamber 4. The secondary water tank 3011 is arranged above the mixing chamber 4 and is connected to the water mist activation device 302. The secondary water tank 3011 is used to form a transfer water supply above the water carrier negative ion generating structure. The water pump 3014 is used to transport water from the main water tank 3013 to the secondary water tank 3011. The water supply device 301 provided in this embodiment has a reasonable structural layout, which can form a closed-loop water circulation system for water storage, water supply, and condensate. Compared with the traditional open water supply system, the water saving rate is significantly improved, and condensate loss is reduced. Preferably, the water storage capacity of the main water tank 3013 is greater than that of the auxiliary water tank 3011. In this case, the water carrier negative ion generator can be arranged with a low center of gravity, improving the arrangement stability of the water carrier negative ion generator. At the same time, it can also ensure that the water guide 3012 and the water mist generating device 302 connected to the auxiliary water tank 3011 can absorb water evenly, and ensure more stable water mist generation.

[0028] In one embodiment, the air negative ion generator 2 includes an air supply mechanism 203 and a negative ion generator 202; The air supply mechanism 203 is arranged below the housing 1 and parallel to the main water tank 3013. This arrangement ensures that the air supply mechanism 203, which provides airflow to the internal airflow channel 201, is positioned alongside the main water tank 3013. This allows for a rational structural layout, with the upper part of the water carrier negative ion generator primarily serving as the intermediate water transfer section (auxiliary water tank 3011), the middle part primarily serving as the output section of the water carrier negative ion generator structure (internal and external airflow channels, water mist activation device 302, mixing chamber 4, negative ion generator 202), and the lower part primarily serving as the energy supply section (water supply from the main water tank 3013 and air supply from the air supply mechanism 203). In this configuration, the water carrier negative ion output of the water carrier negative ion generator is mainly located in the middle of the device, ensuring aesthetics while preventing the water carrier negative ions from being too close to the ground, thus increasing the output distance and cleanliness. The energy supply unit is located at the bottom, which ensures the low center of gravity of the device, while the intermediate water supply unit is located at the top, which can make reasonable use of gravity to supply water to the water mist agitator 302 and ensure the stability of the water supply to the water mist agitator 302.

[0029] In one embodiment, the negative ion generator 202 includes a discharge needle and a negative ion discharge needle cleaning device 6; Reference Appendix Figure 13 - Appendix Figure 16 The negative ion discharge needle cleaning device 6 includes a fixed support 601, a movable support 602, a linear drive assembly 603, and a cleaning component 604. The fixed support 601 and the discharge needle are disposed inside the internal airflow channel 201; the linear drive assembly 603 is fixedly disposed outside the internal airflow channel 201, and preferably disposed on the side of the internal airflow channel 201 away from the mixing chamber 4.

[0030] In this embodiment, the movable support 602 and the fixed support 601 are slidably connected to each other; the movable support 602 is connected to the linear drive assembly 603; furthermore, the cleaning member 604 is provided with a cleaning channel 6041 through which the discharge needle passes; thereby, by driving the movable support 602 to move coaxially relative to the fixed support 601 through the linear drive assembly 603, the cleaning member 604 is moved coaxially relative to the installed discharge needle, so that the inner surface of the cleaning channel 6041 slides into contact with the outer surface of the discharge needle to clean the outer surface of the discharge needle; wherein, when the cleaning member 604 is installed on the fixed support 601, the discharge needle can be installed on the movable support 602; when the cleaning member 604 is installed on the movable support 602, the discharge needle can be installed on the fixed support 601.

[0031] Reference Appendix Figure 15 - Appendix Figure 16According to one embodiment of the present invention, the cleaning member 604 is provided with an elastic cleaning part 604a; wherein, a cleaning channel 6041 is arranged on the elastic cleaning part 604a and the cleaning channel 6041 penetrates the body of the elastic cleaning part 604a.

[0032] Reference Appendix Figure 15 - Appendix Figure 16 According to one embodiment of the present invention, the cleaning channel 6041 is a variable-diameter channel with a variable diameter along its axial direction. The diameter of the cleaning channel 6041 can be set to gradually decrease. Therefore, based on the gradually decreasing radial dimension, the cleaning channel 6041 can adapt to the dimensional changes of the outer surface of the discharge needle during its movement relative to the discharge needle. This allows the cleaning channel 6041 in the cleaning member 604 of the present invention to fully conform to the outer surface of the discharge needle, enabling sufficient sliding wiping of the outer surface of the discharge needle, which is more beneficial to ensuring the cleaning effect of the present invention. Furthermore, through the contact between the cleaning channel 6041 and the discharge needle, the inner surface of the cleaning channel 6041 and the outer surface of the discharge needle generate friction, thereby achieving cleaning of the outer surface of the discharge needle. The radial dimension of the cleaning channel 6041 can be smaller than the radial dimension of the outer surface of the discharge needle. Therefore, during the sliding fit, the elastic deformation of the cleaning channel 6041 can fully conform to the outer surface of the discharge needle, resulting in a better wiping effect and thus a better cleaning effect of the present invention.

[0033] In this embodiment, the elastic cleaning part 604a is made of wear-resistant and elastic materials such as rubber or silicone, thereby enabling the cleaning part 604 of the present invention to have a long service life and high reliability.

[0034] According to one embodiment of the present invention, the cleaning component 604 includes an annular body 604b; wherein an elastic cleaning portion 604a is coaxially and fixedly connected to the front end of the annular body 604b. In this embodiment, an annular connecting portion is provided at the front end of the elastic cleaning portion 604a, thereby achieving a fixed connection with the front end of the annular body 604b through the outer edge of the annular connecting portion. Therefore, the cleaning component 604 can be installed by fitting the annular body 604b onto the front end of a corresponding structure (such as a fixed support 601 or a movable support 602).

[0035] Reference Appendix Figure 3 In one embodiment, the air negative ion generator 2 further includes an air supply channel 204; The air supply channel 204 is arranged on the side of the mixing chamber 4 away from the opening 102; The mixing chamber 4, air supply channel 204, air supply mechanism 203, and main water tank 3013 are arranged in a rectangular pattern. In this embodiment, the mixing chamber 4, air supply channel 204, air supply mechanism 203, and main water tank 3013 are arranged closely together, with high compactness, while ensuring good air supply and mixing effects.

[0036] Reference Appendix Figure 1 In one embodiment, the outer casing 9 is provided with an air inlet 901 on at least one side in the direction of the opening 102; The air inlet side of the air supply mechanism 203 is correspondingly arranged with the air inlet 901. In this embodiment, the air inlet 901 and the opening 102 for outputting negative ions from the water carrier are located on different sides of the device, which can avoid mutual interference between the two while ensuring the air supply intensity and the output intensity of negative ions from the water carrier. Preferably, there are two air inlets 901, which are arranged on opposite side walls of the outer casing 9. Preferably, the air supply mechanism 203 adopts a dual-inlet fan, with the two air inlets corresponding to the two air inlets 901, thereby improving the air supply intensity.

[0037] Reference Appendix Figure 4 - Appendix Figure 12 In one embodiment, the output components of the air negative ion generator 2 and the water mist generator 3 are located within the inner cavity 101 of the housing 1. The output component of the air negative ion generator 2 includes an internal airflow channel 201, within which an airflow containing negative air ions is formed. The output component of the water mist generator 3 includes a water mist excitation device 302 for generating water mist. It should be noted that the water mist may also contain its own negative water ions, thereby increasing the negative ion content of the water-carrier negative ions. The housing 1 and the inner airflow channel 201 of the air negative ion generator 2 form an annular outer airflow channel 5. The annular outer airflow channel 5 is hollow inside and has one end as the outlet. That is, except for the outlet end, the annular outer airflow channel 5 is a relatively closed structure, which isolates the annular outer airflow channel 5 and the inner airflow channel 201 from each other in the flow direction of the inner air negative ion airflow. This can prevent water mist from entering the inner airflow channel 201 and affecting the service life of the negative ion generator 202. Specifically, the inner wall of the inner cavity 101 and the outer wall of the inner airflow channel 201 form an annular outer airflow channel 5 surrounding the outer wall of the inner airflow channel 201. It should be noted that the annular outer airflow channel 5 can be a ring structure with the ends connected in a complete circle around the inner airflow channel 201, or it can be an arc-shaped structure or a semi-circular ring structure with the ends not connected in a complete circle around the inner airflow channel 201. The inner airflow channel 201 and the annular outer airflow channel 5 are isolated from each other by the outer wall of the inner airflow channel 201; the water mist generating device 3 is used to generate water mist in the annular outer airflow channel 5; The common outlet end of the annular outer airflow channel 5 and the inner airflow channel 201 within the housing 1 is a mixing chamber 4. Specifically, the end of the inner airflow channel 201 facing the opening 102 is the outlet end, and the outlet end of the annular outer airflow channel 5 located at the outlet end of the inner airflow channel 201 is also the outlet end; that is, the outlet ends of both the annular outer airflow channel 5 and the inner airflow channel 201 are located on the outlet plane of the inner airflow channel 201. At this time, the remaining portion of the inner cavity 101, excluding the annular outer airflow channel 5 and the inner airflow channel 201, constitutes the mixing chamber 4. The mixing chamber 4 is used to mix the inner air negative ion airflow with water mist to form water-carrier negative ions. The mixing chamber 4 is used to ensure that the output path of the contained negative air ion airflow is unobstructed, and to cause the water mist flowing after ejection to be deflected and / or eddyed within the mixing chamber 4 to enhance the mixing of the water mist and the contained negative air ion airflow; thereby enhancing the mixing of the contained negative air ion airflow and the water mist without directly affecting the output distance of the contained negative air ion airflow; wherein, the water mist is deflected and / or eddyed to increase the depth of water mist penetration into the contained negative air ion airflow, improve the mixing effect of the contained negative air ion airflow and the water mist, and ultimately increase the content of air negative ions attached to the water mist. Ensuring an unobstructed output path for the internal air negative ion airflow means that no structure within the mixing chamber 4 intrudes into the outlet projection range of the internal airflow channel 201 in the outlet direction, and does not generate any structural flow resistance to the internal air negative ion airflow, thus avoiding a reduction in the delivery distance of the internal air negative ion airflow. At this time, the structure (mixing enhancement structure) set in the mixing chamber 4 for guiding water mist into the internal air negative ion airflow and the influence of the guided water mist on the delivery distance of the internal air negative ion airflow can be ignored. Furthermore, since the water mist combines with the internal air negative ion airflow, it greatly improves the quality of the airflow. Therefore, it not only does not reduce the delivery distance of the internal air negative ion airflow, but also increases the delivery distance of the water carrier negative ions due to the formation of water carrier negative ions, ultimately achieving the goal of increasing the negative ion content while increasing the transmission distance.

[0038] Reference Appendix Figure 6 In practical operation, the air negative ion generator 2 forms an internal air negative ion airflow within the internal airflow channel 201, generating an entraining effect. This internal air negative ion airflow acts as the entraining flow, drawing water mist from the annular external airflow channel 5 as the entrained flow. The water mist in the annular external airflow channel 5 flows with the internal air negative ion airflow and undergoes gas-liquid mixing within the mixing chamber 4 through a mixing enhancement structure. After gas-liquid mixing, water-carrier negative ions are formed (see attached diagram). Figure 6 The solid and hollow solid arrows are arranged alternately inside the negative ion output port 701 of the water carrier, which is the water molecule particles with negative air ions attached to the water mist, and then output.

[0039] It should be noted that, because the water mist itself contains negative water ions, the water-carrier negative ions combine with the negative ions in the airflow and the water-carrier negative ions in the water mist, resulting in a higher negative ion content. Furthermore, because the negative ions are carried or propelled by water molecules, the output distance and suspension time of the negative ions are greatly improved. The gas-liquid mixing in the mixing chamber 4 can increase the negative ion content of the output water-carrier negative ions and prevent local aggregation of negative ions, ensuring the uniform distribution of negative ions in the output airflow.

[0040] The water-carrier negative ion generating structure provided by this invention has the following effects: I. By utilizing the internal airflow channel 201, the annular external airflow channel 5, and the mixing chamber 4, the method ensures the transport distance of the negative ions while increasing the content of negative ions in the water carrier. This also solves the contradictory problem in existing technology 1 (CN208316022U A Hydrated Negative Oxygen Ion Generating Device) where the transport distance is sacrificed to improve the mixing effect.

[0041] Second, by utilizing the structural arrangement of the inner airflow channel 201, the annular outer airflow channel 5, and the mixing cavity 4, the space of the inner cavity 101 is fully utilized, thereby significantly improving the output distance and negative ion content while maintaining a compact structure.

[0042] Third, due to the design of the inner and outer ducts, the water mist can be isolated from the negative ion generator 202 in the air negative ion generator 2. Combined with the delivery direction of the inner air negative ion airflow in the inner airflow channel 201, the water mist can be completely prevented from entering the inner airflow channel 201 and affecting the service life of the negative ion generator 202, thus solving the problem that the traditional negative ion generator 202 is prone to moisture damage.

[0043] Fourth, the air negative ion generator 2 forms an internal air negative ion airflow in the internal airflow channel 201, which is used as both the output power source for water carrier negative ions and to drive the water mist in the annular external airflow channel 5 to flow. This eliminates the need for an independent driving element for the flow of water mist, reduces structural complexity, and improves the utilization rate of the air supply mechanism 203 in the air negative ion generator 2.

[0044] Fifth, the output of negative ions carried by the water carrier contains water molecules, which can purify the water molecules and control the ambient humidity by adjusting the amount of water mist.

[0045] VI. Instead of arranging the internal negative air ion airflow in the annular outer duct airflow channel 5 and the internal airflow channel 201, water mist is arranged in the annular outer duct airflow channel 5 and water mist is arranged in the internal airflow channel 201. This avoids the problem of the fan blowing air directly acting on the heavier water mist, which would limit the distance of water carrier transportation.

[0046] In one embodiment, a water carrier negative ion output port 701 is provided on the housing 1 in the axial extension direction of the internal airflow channel 201; in this case, the water carrier negative ion output port 701 functions as the opening 102 of the housing 1, and at least part of the internal air negative ion airflow output from the internal airflow channel 201 can be directly and unobstructedly output to the target location through the water carrier negative ion output port 701 (see attached figure). Figure 6 (The hollow solid arrow in the diagram represents the internal air negative ion airflow). This means the diameter of the water carrier negative ion outlet 701 is larger than the inner diameter of the internal airflow channel 201, but smaller than the outer diameter of the annular outer airflow channel 5. When the projection of the internal airflow channel 201 in the outlet direction is within the projection of the water carrier negative ion outlet 701 in the outlet direction, all the internal air negative ion airflow can be directly and unobstructed through the water carrier negative ion outlet 701 and output to the target location, avoiding flow resistance to the internal air negative ion airflow. This increases the delivery distance of the water carrier negative ions on one hand, and ensures the flow velocity and pressure of the internal air negative ion airflow on the other, thereby ensuring the ejection effect. The mixing chamber 4 is provided with a mixing enhancement structure for enhancing the mixing of internal air negative ion airflow and water mist. The mixing enhancement structure includes a water mist impact surface I702, which is disposed on at least a portion of the wall surface of the shell 1 located in the axial extension direction of the annular outer airflow channel 5; that is, at least a portion of the outlet end of the annular outer airflow channel 5 is not on the water carrier negative ion output port 701. The water mist (attached) in the annular outer bypass airflow channel 5 caused by the ejector effect Figure 6 At least a portion of the solid arrowhead (in the middle section) impacts the water mist impact surface I702 after flowing with the internal air negative ion airflow, causing it to be redirected and diffused. The redirected water mist is injected into the internal air negative ion airflow, mixed, and then output from the water carrier negative ion output port 701. This configuration has the following effects: 1. A portion of the water mist ejected by the internal airflow containing negative ions will not flow out unimpeded through the negative ion output port 701. Instead, it will collide with the water mist impact surface I 702 and be redirected, forming localized turbulence in the latter part (see appendix). Figure 6The solid arc arrow section in the middle, and the other part of the water mist moves towards the inner air negative ion airflow, and finally enters the inner air negative ion airflow for mixing, breaking the original gas-liquid stratified flow, strengthening the gas-liquid two-phase turbulent mixing, so that the air negative ions and the tiny water mist particles can fully contact each other, significantly improving the mixing effect of the inner air negative ion airflow and water mist.

[0047] II. The redirecting water mist will carry the water mist through the water carrier negative ion output port 701 without obstruction (see attached image). Figure 6 The solid dotted arrows in the middle turn together, thereby ensuring that all water mist passing through the water carrier negative ion output port 701 has a tendency to enter the internal air negative ion airflow, significantly improving the mixing effect of the internal air negative ion airflow and water mist.

[0048] 3. After the redirecting water mist pushes the unobstructed water mist, the unobstructed water mist will mix more thoroughly with the internal airflow of negative ions. The redirecting water mist, due to the resistance generated by the redirection and the resistance generated by pushing the unobstructed water mist, will have a reduced flow velocity. This, combined with the formation of localized turbulence, creates water mist surrounding the outside of the mixed water-carrying negative ions (see appendix). Figure 6 The solid and dashed arrows on the outside of the negative ion output port 701 of the water carrier are used to reduce the escape rate of negative ions.

[0049] IV. The large water mist particles generated by the water mist excitation device 302 (due to the limitations of the water mist excitation device 302 or the inevitable existence of large water molecules due to the fusion of tiny water molecules) collide with the water mist impact surface I702 after being attracted by the air negative ion flow. After the collision, at least some of them will break down, reducing the particle size of the large water molecules, refining the water mist, and thus improving the utilization rate of the water mist generated by the water mist excitation device 302.

[0050] 5. The water mist impact surface I702 is continuously impacted by water mist, which has the effects of self-cleaning and anti-scaling.

[0051] For example, the structure of the water mist impact surface I702 of the blending and reinforcing structure can be an inclined plane, thereby causing the water mist to turn vertically or at an acute angle. The inclined angle is preferably 30°-45°. Too small an angle will result in insufficient water mist penetration and incomplete mixing; too large an angle will cause backflow interference and ejection effects. It can also be an arc surface, which allows the water mist to flow smoothly while turning it, reducing turning resistance. It can also be a flow-around protrusion, groove or circular hole provided on the inclined plane or arc surface, which can generate deflection and / or vortex of water mist. In a preferred embodiment, the water mist impact surface I702 is an inner arc surface structure, which is formed by transition with the inner sidewall of the shell 1, and the center of the inner arc surface structure is located in the blending cavity 4. At this time, after guiding the water mist to move, the inner wall of the shell 1 turns after passing through the inner arc surface structure of the rounded corner structure. During the turning process, the arc surface structure can reduce the turning resistance and form the Coanda wall to accelerate the flow. Since it is an inner arc surface structure, it can increase the volume of the mixing cavity 4 on the one hand, and improve the guiding performance on the other hand.

[0052] In a preferred embodiment, the surface of the water mist impact surface I702 is provided with a hydrophobic coating to prevent water mist from adhering to the water mist impact surface I702.

[0053] In one embodiment, the projection of the outlet direction of the internal airflow channel 201 is located within the projection of the outlet direction of the water carrier negative ion output port 701. That is, the channel area of ​​the internal airflow channel 201 is smaller than the channel area of ​​the water carrier negative ion output port 701, so that the internal air negative ion airflow can be directly output through the water carrier negative ion output port 701 without obstruction, thereby ensuring the flow rate of the internal air negative ion airflow and ensuring the delivery distance of the water carrier negative ions.

[0054] For example, the cross-sections of the internal airflow channel 201 and the water carrier negative ion output port 701 can be rectangular, triangular, or other irregular structures, which only require the flow of internal air negative ion airflow and water carrier negative ions. In a preferred embodiment, the cross-sections of the internal airflow channel 201 and the water carrier negative ion output port 701 are circular, which can ensure the area of ​​the internal airflow channel 201 and the water carrier negative ion output port 701, while avoiding dead corners that increase the difficulty of cleaning.

[0055] The water-carrier negative ion output port 701 can be a hole located on the end wall of the housing 1, or it can be a channel structure. In a preferred embodiment, the water-carrier negative ion output port 701 is a channel structure. This configuration, compared to a hole structure, provides a stable and smooth flow, rectifying the output of water-carrier negative ions, reducing turbulence, and ultimately slowing down the diffusion of the water-carrier negative ion jet. Furthermore, the channel allows for more time for the gas and liquid phases to mix, improving the mixing effect. Additionally, the channel maintains the concentration of water-carrier negative ions, providing guidance for their output and making it easier to control the output direction and velocity. Moreover, the channel structure, in conjunction with the water mist impact surface I 702, can re-rectify the redirected water mist passing through the impact surface I 702, correcting any deviations in turbulence. Furthermore, the channel structure, in conjunction with the mixing chamber 4, allows the strong turbulence within the mixing chamber 4 to gradually attenuate to weak turbulence at the channel structure inlet through boundary layer development, forming a stable long-distance transport of water-carrier negative ions.

[0056] The water carrier negative ion output port 701 can be a channel with a constant cross-section, a gradually expanding cross-section, or a reduced cross-section along the axial direction. In a preferred embodiment, the water carrier negative ion output port 701 is a channel with a constant cross-section. This eliminates local resistance loss caused by abrupt changes in cross-section and ensures a uniform flow velocity distribution of the gas-liquid mixture of water carrier negative ions.

[0057] In one embodiment, the outlet end of the water carrier negative ion output port 701 is provided with a grid guide 704. The grid guide 704 consists of multiple parallel straight or arc-shaped guide vanes (spaced 6.5mm-10.5mm) that can divide the outlet water carrier negative ions into multiple jets, forcing the airflow to flow axially in a directional manner and improving the uniformity of the flow field. In addition, the grid guide 704 can also prevent foreign objects from entering the mixing chamber 4.

[0058] In one embodiment, the blending and reinforcing structure further includes a water mist impact surface II 703, which is disposed at the inlet end of the water carrier negative ion output port 701; the inlet end of the water carrier negative ion output port 701 is provided with the water mist impact surface II 703, that is, the inlet end of the water carrier negative ion output port 701 and the end face of the shell 1 or the end of the water mist impact surface I 702 form an inclined water mist impact surface. At least a portion of the water mist within the annular outer airflow channel 5, driven by the ejector effect, impacts the water mist impact surface II 703 after flowing with the inner air negative ion airflow, causing it to be redirected and diffused. The water mist is injected into the inner air negative ion airflow, mixes, and is output from the water carrier negative ion output port 701. In addition to possessing the effects of the water mist impact surface I 702, the water mist impact surface II 703 can, on the one hand, form a guiding slope at the inlet of the water carrier negative ion output port 701, forcing the gas-liquid two-phase mixed airflow to complete flow direction correction before entering the equal channel structure. On the other hand, it can also guide the airflow to flow along the wall, providing guidance for the water carrier negative ions.

[0059] For example, the structure of the water mist impact surface II 703 can be an inclined plane, thereby causing the water mist to turn vertically or at an acute angle. The inclination angle is preferably 30°-45°. Too small an angle will result in insufficient water mist penetration and incomplete mixing; too large an angle will cause backflow interference and entrainment effects. 30°-45° can form a guide ramp at the inlet of the water carrier negative ion output port 701, or it can be an arc surface, or it can be a flow-around protrusion, groove, or round hole provided on an inclined plane or arc surface. Any structure that can cause the water mist to deflect and / or vortex is acceptable. While turning the water mist, it can also allow the water mist to flow smoothly, reducing turning resistance. In one preferred embodiment, the water mist impact surface I 702 is an inner arc surface structure; the water mist impact surface II 703 is an outer arc surface structure tangent to the water mist impact surface I 702. The water mist impact surface I 702 is an inner arc surface structure, which allows the water mist to turn naturally along the arc surface after impact, reducing resistance and promoting more uniform diffusion. The outer arc-shaped structure of the water mist impact surface II 703, which is tangent to the inner arc-shaped structure, enables a smooth flow transition, reduces energy loss, and allows the water mist to mix with the internal negative ion airflow at a more suitable angle and velocity. The tangential design may reduce flow separation, avoid the formation of dead zones, and improve mixing efficiency. Furthermore, the tangential design of the outer arc-shaped structure and the inner arc-shaped structure can generate a Venturi effect at the inlet of the water carrier negative ion outlet 701, increasing the local flow velocity. Additionally, the connection between the outer arc-shaped structure of the water mist impact surface II 703 and the inlet of the channel structure of the water carrier negative ion outlet 701 creates a more uniform flow field at the channel inlet, reducing turbulence and thus improving overall output efficiency and stability.

[0060] In one embodiment, the water carrier negative ion generating structure further includes an air guide 7 disposed in the mixing chamber 4. The air guide 7 includes an annular sidewall that fits into the sidewall of the housing 1 and an end wall that connects to one end of the annular sidewall. The end wall corresponds to the outlet direction of the internal airflow channel 201. The water carrier negative ion output port 701, water mist impact surface I 702, and water mist impact surface II 703 are disposed on the end wall; by providing the air guide 7, the opening 102 of the housing 1 can be made large enough to facilitate the installation of the air negative ion generator 2 and the water mist generator 3, and the air guide 7 can be made into a detachable structure, thereby realizing the cleaning and maintenance of the water carrier negative ion output port 701, water mist impact surface I 702, water mist impact surface II 703, inner cavity 101, and inner airflow channel 201; Reference Appendix Figure 5 and attached Figure 9 The bottom of the housing 1 is conical to collect condensate formed by water mist in the inner cavity 101 and the air guide 7. An overflow outlet 103 is provided at the bottom of the conical shape to discharge the condensate, which can be used for recycling in the water mist generator 3 or directly discharged as wastewater. The bottom of the annular sidewall is spaced from the bottom of the housing 1, forming an overflow inlet 104. Condensate flowing to the bottom of the inner cavity 101 flows directly into the overflow outlet 103 due to the conical structure. Preferably, the overflow outlet 103 is connected to the main water tank 3013 for collecting condensate for recycling. Condensate on the annular sidewall, end wall, water carrier negative ion output port 701, water mist impact surface I 702, and water mist impact surface II 703 of the air guide 7 flows from the bottom wall of the annular sidewall to the spacer, ensuring that all condensate can flow smoothly to the overflow outlet 103. With this configuration, the annular sidewall of the air guide 7 forms the mixing chamber 4. This air guide 7 can ensure the size of the mixing chamber 4 and also ensure the configuration of the water mist impact surface Ⅰ702 on the bottom wall (bottom wall of the annular sidewall) of the mixing chamber 4.

[0061] In one embodiment, the internal airflow channel 201 is a circular channel, the inner diameter of the internal airflow channel 201 is 34mm-38mm, and the outer diameter of the internal airflow channel 201 is 39mm-42mm; and / or The inner cavity 101 enclosed by the housing 1 and the air guide 7 is a rectangular cavity with a length of 94mm-98mm, a width of 78mm-82mm, and a depth of 76mm-80mm; and / or The axis of the internal airflow channel 201 is coaxial with the central axis of the plane containing the length and width of the air guide 7, that is, the distances from the left and right sides of the internal airflow channel 201 to the left and right sides of the air guide 7 cavity are the same, and the distances from the top and bottom sides of the internal airflow channel 201 to the top and bottom sides of the air guide 7 cavity are the same; and / or The distance between the outlet of the internal airflow channel 201 and the end wall of the air guide 7 is 13.5mm-17.5mm; and / or The water carrier negative ion output port 701 has a constant cross-section channel structure, with an inner diameter of 48mm-52mm and a length of 23mm-27mm; and / or The water mist impact surface I702 has an inner arc surface structure, and the diameter of the water mist impact surface I702 is 22mm-26mm; and / or The water mist impact surface II703 has an outer arc surface structure, and the diameter of the water mist impact surface II703 is 21mm-25mm.

[0062] Using the above technical solution, when two sets of internal airflow channel 201, negative ion generator 202, annular external airflow channel 5, and water mist generator 3 are arranged horizontally side by side, experimental verification shows that the amount of negative ions can reach 30,000 / cm³ at a distance of 10 meters from the negative ion output port 701 of the water carrier. 3 Specifically, 2m > 600,000 cells / cm² 3 4m > 200,000 cm 3 6m > 70,000 / cm 3 10m > 30,000 / cm 3 The delivery distance and concentration of negative ions are significantly improved. At its highest setting, the noise level is less than 45 decibels, meeting the requirements for quiet operation.

[0063] In one embodiment, reference is made to the appendix. Figure 9 The water mist generating device 3 includes a water supply device 301 and a water mist activation device 302 connected to each other. Preferably, the water supply device 301 is an auxiliary water tank 3011, wherein the water supply device 301 is used to supply water to the water mist activation device 302, and the water mist activation device 302 is used to generate water mist through vibration. Specifically, the water mist activation device 302 includes a vibrating plate and micropores disposed on the vibrating plate. Preferably, according to experiments, the pore size of the micropores is 1.6μm-2μm. At this time, the water retention rate at the outlet of the negative ion output port 701 can be reduced, and the water consumption is 0.12g / min, thereby reducing the water consumption rate, saving water resources, and reducing the frequency of water addition. The water mist generating device 302 is arranged inside the annular outer bypass airflow channel 5, thereby providing water mist to the annular outer bypass airflow channel 5.

[0064] In one embodiment, the water mist output direction of the water mist generating device 3 is set towards the mixing cavity 4, that is, the water mist generated by the vibration of the vibrating plate flows slowly towards the mixing cavity 4, which improves the ejection effect and reduces the water retention rate on other side walls of the annular outer duct airflow channel 5.

[0065] In one embodiment, reference is made to the appendix. Figure 10The water mist generating device 302 is provided on each side of the inner airflow channel 201, thereby increasing the amount of water mist in the annular outer airflow channel 5 to be sufficient and uniform.

[0066] In one embodiment, at least two of the water mist generating devices 302 are evenly arranged in the vertical direction in each group; Each group of two water mist generating devices 302 is independently controlled, and at least one water mist generating device 302 in each group is activated at the same time. In a preferred embodiment, two groups of water mist generating devices 302 are arranged in one inner cavity 101, with two devices evenly arranged vertically in each group, for a total of four water mist generating devices 302. This allows each water mist generating device 302 to be used alternately, doubling the service life of the water mist generating device 302 while ensuring the effectiveness of the water carrier negative ion generating structure. It is particularly suitable for long-term uninterrupted use.

[0067] In one embodiment, the water supply device 301 includes a secondary water tank 3011 disposed above the housing 1 and a water guide 3012 connecting the bottom of the secondary water tank 3011 and the water mist generating device 302. By placing the secondary water tank 3011 on top, water can be transported on the water guide 3012 by gravity, thereby saving a water transport device.

[0068] In one embodiment, reference is made to the appendix. Figure 5 The air negative ion generating device 2 includes a negative ion generator 202 and an air supply mechanism 203; The air outlet of the air supply mechanism 203 is connected to the inlet of the internal airflow channel 201. It is used to provide airflow to the internal airflow channel 201.

[0069] For example, the negative ion generator 202 can be disposed at the outlet of the air supply mechanism 203; or disposed on the air supply channel 204 between the air supply mechanism 203 and the internal airflow channel 201. Preferably, the negative ion generator 202 is disposed within the internal airflow channel 201. This arrangement allows negative ions to be generated in a high-speed airflow, avoiding the negative ion attenuation caused by airflow transmission in traditional external negative ion generators. Furthermore, it can also accelerate the removal of charged particles from the negative ion generator 202 by the high-speed airflow. Further, the negative ion generator 202 is arranged in the center of the internal airflow channel 201 via a grid support. This allows for symmetrical distribution and uniform diffusion of negative ions. It also allows the heat from the electrodes at the center of the negative ion generator 202 to be dissipated evenly through the annular airflow, solving the heat dissipation problem of the negative ion generator 202.

[0070] In one embodiment, at least two sets of the inner airflow channel 201, negative ion generator 202, annular outer airflow channel 5, and water mist generator 3 are arranged horizontally side by side; wherein, the annular outer airflow channel 5 can be divided into two sets by a partition 705 arranged in the middle of the inner cavity 101. In this embodiment, the total cavity enclosed by the shell 1 and the air guide 7 has a length of 188mm-196mm and a width of 156mm-164mm, and the total cavity is divided into two independent inner cavities 101 by the partition 705.

[0071] The air outlet of the air supply mechanism 203 is simultaneously connected to the inlets of multiple internal airflow channels 201, meaning that airflow can be generated within multiple sets of internal airflow channels 201 through a single air supply mechanism 203. This configuration allows the negative ion content and water mist content to be doubled using only one air supply mechanism 203.

[0072] In one embodiment, an electrostatic elimination structure 8 is also provided in the annular sidewall of the air guide 7 to ground the static electricity in the mixing chamber 4 and ensure that the mixing chamber 4 is anti-static.

[0073] Reference Appendix Figure 17 - Appendix Figure 18 In one embodiment, the static electricity elimination structure 8 includes an annular conductive body 801 and a grounding connection cap 802 disposed on the annular conductive body 801. The annular conductive body 801 forms the overall shape of the static electricity elimination structure 8 to achieve matching installation with a corresponding position on the annular sidewall of the air guide 7. In this embodiment, the annular conductive body 801 has a through hole penetrating its sidewall; the grounding connection cap 802 is disposed corresponding to the through hole on the sidewall of the annular conductive body 801. In this embodiment, the grounding connection cap 802 is a hollow structure with one open end and the other closed end, and the hollow part of the grounding connection cap 802 is connected to the through hole. Therefore, the grounding post can be easily and stably inserted into the grounding connection cap 802 through the grounding connection cap 802. Furthermore, based on the conductivity between the grounding post and the grounding connection cap 802, static electricity on the annular conductive body 801 can be discharged to the corresponding ground wire, thereby achieving the effect of eliminating static electricity.

[0074] In a preferred embodiment, the annular conductive body 801 is made of a conductive ABS ring reinforced with carbon fiber (or carbon powder), and the resistance between the two furthest test points is ≤500 ohms. This configuration facilitates the elimination of static electricity. In this embodiment, the carbon fiber (or carbon powder) reinforced conductive ABS ring is a readily available and mature material; it can be used as long as the above-mentioned conditions are met, and therefore will not be elaborated further.

[0075] According to one embodiment of the present invention, the static elimination structure 8 of the present invention further includes: a partition support member 803; wherein, the partition support member 803 is a long strip structure, and the opposite ends of the partition support member 803 are respectively connected to two opposite sides of the annular conductive body 801. In this embodiment, the annular conductive body 801 can be configured as a symmetrical annular structure, thereby the partition support member 803 can be placed at the middle position of the annular conductive body 801, and the conduction path on the annular conductive body 801 can be made symmetrical by the annular conductive body 801 placed at the middle position, which is more beneficial to improving the static elimination effect of the present invention. In a specific embodiment, the partition support member 803 covers the upper side of the partition 705 of the air guide member 7 to ensure the annular conductive coverage effect of the two inner cavities 101.

[0076] According to one embodiment of the present invention, two spacer supports 803 are provided at intervals. The spaced arrangement of two spacer supports 803 enriches the conductive paths of the present invention, thus improving its static electricity elimination effect. Furthermore, the spaced arrangement of two spacer supports 803 allows for compatible connection with other structures, effectively ensuring the connection reliability and reliable maintenance of the external structure of the present invention. In a specific embodiment, when at least two sets of the inner airflow channel 201, negative ion generator 202, annular outer airflow channel 5, and water mist generator 3 are horizontally arranged side-by-side, the two spacer supports 803 cover both sides of the partition 705 to further improve the annular conductive coverage effect of the inner cavity 101.

[0077] According to one embodiment of the present invention, a plurality of grounding connection caps 802 are provided at intervals, and the plurality of grounding connection caps 802 are arranged at intervals on the annular conductive body 801; correspondingly, the plurality of grounding connection caps 802 are symmetrically arranged on opposite sides of the separating support member 803. In this embodiment, the number of grounding connection caps 802 can be even (e.g., 2, 4, etc.), thereby, by providing a plurality of grounding connection caps 802 and arranging them symmetrically, the efficiency of the present invention in eliminating static electricity can be more effectively improved.

[0078] According to one embodiment of the present invention, the annular conductive body 801, the grounding connection cap 802, and the partition support 803 are an integral structural component.

[0079] The above settings effectively ensure the overall molding of the static elimination structure 8, thereby significantly improving its production efficiency and reducing its production costs.

[0080] According to one embodiment of the present invention, the sidewall cross-section of the annular conductive body 801 is rectangular. The long side of the sidewall cross-section of the annular conductive body 801 is arranged parallel to the axial direction of the annular conductive body 801. This allows the sidewall of the annular conductive body 801 to have a flat structure, thereby giving the annular conductive body 801 a certain width in the axial direction. This results in a larger contact area on the sidewall of the annular conductive body 801, which is more beneficial for electrostatic adsorption in the installation space.

[0081] Preferably, the annular conductive body 801 is arranged at the mixing cavity 4 of the air guide 7, which can improve the static electricity treatment effect in the mixing cavity 4.

[0082] In one embodiment, reference is made to the appendix. Figure 5 An air supply channel 204 is also provided between the air outlet of the air supply mechanism 203 and the inlet of the internal airflow channel 201; The air supply channel 204 includes a horizontal portion 2041 and a vertical portion 2042 arranged sequentially. The outer end of the horizontal portion 2041 is connected to the inlet of the internal airflow channel 201, and the outer end of the vertical portion 2042 is connected to the air outlet of the air supply mechanism 203. In this embodiment, the air supply channel 204 can shorten the horizontal dimension of the water carrier negative ion generating structure, thereby reducing the indoor area occupied, and can also increase the height of the water carrier negative ion output port 701 from the ground to ensure the delivery distance. On the other hand, it can optimize the air duct structure and ensure that it evenly distributes the air volume to the multiple internal airflow channels 201.

[0083] In one embodiment, the top of the outer casing 9 is provided with circuit board mounting cavities 902 on the front and rear sides of the auxiliary water tank 3011, thereby making reasonable use of the space on the top of the outer casing 9 and facilitating the layout of the control circuit.

[0084] The above description is merely an embodiment and does not constitute any limitation on the present invention. Any person skilled in the art can make many possible variations, modifications, or alterations to the technical solutions of the present invention without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
