Description

Technical Field

[0001] The invention belongs to the field of air treatment equipment, and in particular relates to a water carrier negative ion generating device. Background Art

[0002] Traditional negative ion generators in air purification devices are typically installed externally, for example, at the outlet of the air supply mechanism or at the end of the air supply duct, where the airflow carries the negative ions into the target area. However, this design has certain drawbacks: First, negative ions rapidly decay during long-distance transmission due to collisions with positive ions and particulate matter in the air, causing their effective concentration to drop by 30%-50%. Diffusion efficiency is particularly reduced in high-speed airflows (>5 m / s). Second, external generators require the additional configuration of an ionization chamber and flow guide structure, which increases the 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 use the quality of water mist to increase the transmission distance, but there is a common problem that the transmission distance is still limited.

[0004] For example, prior art 1, "CN208316022U A Hydrated Negative Oxygen Ion Generator," discloses a hydrated negative oxygen ion generator designed to generate hydrated negative oxygen ions and extend their propagation distance. The airflow is arranged within the gap, and a protrusion is provided on the rear edge of the third housing to disturb the airflow. The protrusion disturbs the airflow as oxygen ions and the like flow out, thereby facilitating further mixing of negative ions that are not fully mixed with water vapor and oxygen in the ion generating chamber to form hydrated negative oxygen ions. In the above scheme, the negative ions, water vapor, and oxygen are first mixed within the ion generating chamber. The negative pressure generated by the gap draws them into the gap through the through-holes, and finally, they exit the gap, bypass the protrusion, and enter the ion generating chamber for further mixing. This multiple mixing of the negative ions, water vapor, and oxygen produces a good mixing effect. However, because the third housing is the outer wall of the gap and is also in the airflow path, it creates significant wind resistance to the airflow, seriously affecting its transport distance. In addition, with such an arrangement, the negative ion emission head will come into contact with water vapor, which will seriously affect the service life of the ion emission head.

[0005] In addition, the water supply structure currently generally adopts an upper water tank, which makes the center of gravity of the device unreasonable and cannot recycle condensed water, 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 generating device which can provide long-distance water carrier negative ion transportation and save water resources.

[0007] The present 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 adopts an internal and external airflow duct method to respectively generate an air negative ion airflow and a water mist, and through the induced effect of the air negative ion airflow, guides the water mist to flow in the same direction and mixes and then outputs the water carrier negative ions; the water supply device adopts the form of storing water and condensing water below the water carrier negative ion generating structure and transferring water from above the water carrier negative ion generating structure to supply water to the water carrier negative ion generating structure.

[0008] The beneficial effects of the present invention are as follows: the water carrier negative ion generating device provided by the present invention utilizes the internal and external air flow ducts to generate air negative ion airflow and water mist respectively, and guides the water mist to flow in the same direction and output the water carrier negative ions after mixing through the induced effect of the air negative ion airflow, which has the following effects: First, the structural arrangement of the inner airflow channel, the annular outer airflow channel and the mixing chamber is utilized to achieve a significant increase in the output distance and negative ion content of the negative ions on the basis of a compact structure. Second, due to the design of the internal and external ducts, the water mist can be isolated from the negative ion generator in the air negative ion generating device 2, and the conveying direction of the inner air negative ion airflow of the inner airflow channel can be coordinated to completely prevent the water mist from entering the inner airflow channel to affect the service life of the negative ion generator, thereby solving the problem that the traditional negative ion generator is easily damaged by moisture. Third, the negative air ion generator generates an internal air flow of negative air ions within the internal air flow channel, which serves as both the output power source for the water carrier negative ions and the guide force for the water mist to flow within the annular external air flow channel. This eliminates the need for a separate drive element for the water mist flow, reducing structural complexity and improving the utilization rate of the air supply mechanism in the negative air ion generator. Fourth, the output of the water carrier negative ions carries water molecules, which can purify water molecules, and the ambient humidity can also be controlled by adjusting the amount of water mist.

[0009] The water supply device adopts a structure that stores water and recovers condensed water below the water carrier negative ion generating structure and transfers water from above the water carrier negative ion generating structure to supply water to the water carrier negative ion generating structure, which has the following effects: First, it can form a closed-loop water circulation system for water storage, water supply and condensed water, which significantly improves the water saving rate compared with the traditional open water supply system and reduces the loss of condensed water. Second, by adopting the structure of storing water and recovering condensed water, the bottom of the water carrier negative ion generating device can be the main water storage structure, while the top only retains the water supply structure with a small water storage capacity. In this way, the water carrier negative ion generating device can be arranged with a low center of gravity, thereby improving the layout stability of the water carrier negative ion generating device. Third, when the water mist excitation device in the water carrier negative ion generating structure adopts a water guide to supply water, the small-volume water supply mechanism can avoid excessive water storage, which leads to excessive water pressure and excessive water entering the water guide, thereby ensuring that the water guide and the water mist excitation device can absorb water evenly, and ensuring that the generation of water mist is more stable.

DETAILED DESCRIPTION

[0012] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall 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 position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0014] In addition, the terms "first," "second," and so on, used in this disclosure are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referenced. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this disclosure, "plurality" means at least two, such as two or three, unless otherwise specifically defined.

[0015] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; it can mean mechanical connection, electrical connection, physical connection, or wireless communication connection; it can mean direct connection or indirect connection through an intermediate medium; it can mean internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0017] As attached Figure 1 -Attached 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 adopts the internal and external air flow duct mode to generate air negative ion airflow and water mist respectively, and guides the water mist to flow in the same direction and output the water carrier negative ions after mixing through the entrainment effect of the air negative ion airflow; in specific operation, by forming the inner air negative ion airflow in the inner airflow channel 201 and generating an entrainment effect, the inner air negative ion airflow serves as the entrainment flow, and the water mist in the annular outer airflow channel 5 is guided as the entrained flow, and the inner air negative ion airflow guides the water mist in the annular outer airflow channel 5 to flow with the inner air negative ion airflow and completes gas-liquid mixing in the mixing chamber 4, and the gas-liquid mixing forms the water carrier negative ions (attached) after the gas-liquid mixing. Figure 6 The water carrier negative ions are output through the outlet 701 (the solid arrows and hollow arrows are arranged alternately). The water carrier negative ions combine with the negative ions in the airflow containing negative ions and the negative ions in the water mist, resulting in a higher negative ion content. Furthermore, because they are carried or propelled by water molecules, the output distance and suspension time of the negative ions are greatly 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 distribution of negative ions in the output airflow.

[0018] The water supply device 301 supplies water to the water carrier negative ion generating structure by storing water below the structure, recovering condensed water, and then transferring water from above the structure. This arrangement allows water storage, supply, and condensation to form a closed-loop water circulation system, significantly improving water conservation and reducing condensation losses compared to traditional open water supply systems. Furthermore, by using downward-directed water storage and condensed water recovery, the lower portion of the water carrier negative ion generating structure (main water tank 3013) serves as the primary water storage structure, while the upper portion retains only the water supply structure (auxiliary water tank 3011) with a small water storage capacity. This arrangement allows the water carrier negative ion generating structure to be positioned with a low center of gravity, improving its layout stability. At the same time, when the water mist excitation device 302 in the water carrier negative ion generating structure adopts the water guide 3012 (cotton swab) to supply water, the water supply structure with a small water storage capacity can avoid excessive water storage, resulting in excessive water pressure and excessive water volume entering the water guide 3012, thereby ensuring that the water guide 3012 and the water mist excitation device 302 can absorb water evenly, and ensuring that the generation of water mist is more stable.

[0019] That is, the water carrier negative ion generating device provided by the present invention utilizes the internal and external airflow ducts to generate air negative ion airflow and water mist respectively. Through the induced effect of the air negative ion airflow, the water mist is guided to flow in the same direction and mixed to output water carrier negative ions, which has the following effects: 1. By utilizing the structural arrangement of the inner airflow channel 201, the annular outer airflow channel 5 and the mixing chamber 4, the output distance and the content of negative ions are significantly improved on the basis of a compact structure.

[0020] 2. Due to the design of the internal and external ducts, the water mist can be isolated from the negative ion generator 202 in the air negative ion generating device 2. Combined with the conveying direction of the internal air negative ion airflow of the internal airflow channel 201, the water mist can be completely prevented from entering the internal airflow channel 201 and affecting the service life of the negative ion generator 202, thereby solving the problem that the traditional negative ion generator 202 is easily damaged by moisture.

[0021] 3. The negative air ion generating device forms an internal negative air ion airflow in the internal airflow channel 201, which is used as an output power source for water carrier negative ions and is also used to induce and drive the water mist in the annular external airflow channel 5 to flow, so that the flow of the water mist does not require an independent driving element, reducing the structural complexity and improving the utilization rate of the air supply mechanism 203 in the negative air ion generating device 2.

[0022] 4. The output of water carrier negative ions carries water molecules, which can purify water molecules and control the ambient humidity by adjusting the amount of water mist.

[0023] The water supply device 301 stores water and recovers condensed water below the water carrier negative ion generating structure and transfers water from above the water carrier negative ion generating structure to supply water to the water carrier negative ion generating structure, which has the following effects: 1. It can form a closed-loop water circulation system for water storage, water supply and condensation water, which significantly improves the water saving rate and reduces the loss of condensation water compared with the traditional open water supply system.

[0024] Second, by adopting downward water storage and condensed water recovery, the bottom of the water carrier negative ion generating device can be the main water storage structure (main water tank 3013), while the top only retains the water supply structure with a small water storage capacity (auxiliary water tank 3011). In this way, the water carrier negative ion generating device can be arranged with a low center of gravity, thereby improving the layout stability of the water carrier negative ion generating device.

[0025] 3. When the water mist excitation device 302 in the water carrier negative ion generating structure adopts the water guide 3012 (cotton swab) to supply water, the small volume of the water supply mechanism can avoid excessive water storage, resulting in excessive water pressure and excessive water entering the water guide 3012, thereby ensuring that the water guide 3012 and the water mist excitation device 302 can absorb water evenly, and ensuring that the generation of water mist is more stable.

[0026] In one embodiment, refer to the attached Figure 4 -Attached 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. A mixing chamber 4 and an opening 102 connected to the mixing chamber 4 are provided in the shell 1. 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 are mixed in the mixing chamber 4 and 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 to output the water carrier negative ions, or to install an air 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 connected to 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 in the inner cavity 101 and are then output to the target position through the opening 102. In the water carrier negative ion generating structure of this embodiment, the housing 1 integrates the air negative ion generating device 2 and the water mist generating device 3 into one body, forming a compact water carrier negative ion generating structure, which is convenient for 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 excitation device 302; the water mist excitation device 302 is an output component of the water mist generating device 3, which is used to generate water mist; specifically, the water mist excitation device 302 includes a vibrating plate and micropores provided on the vibrating plate. Preferably, according to experiments, the pore size of the micropores is 1.6 μm-2 μm, which can reduce the water hanging rate at the outlet of the water carrier negative ion output port 701. At this time, the water consumption is 0.12 g / min, reducing the water use 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 an auxiliary water tank 3011. The main water tank 3013 is arranged below the mixing chamber 4. The main water tank 3013 is used to form water storage below the water carrier negative ion generating structure, and the top of the main water tank 3013 is connected to the bottom of the mixing chamber 4, thereby realizing the recovery of condensed water in the mixing chamber 4. The auxiliary water tank 3011 is arranged above the mixing chamber 4, and the auxiliary water tank 3011 is connected to the water mist excitation device 302. The auxiliary water tank 3011 is used to form a transfer water supply above the water carrier negative ion generating structure, and the water pump 3014 is used to transport water from the main water tank 3013 to the auxiliary water tank 3011. The specific structure and reasonable layout of the water supply device 301 provided in this embodiment can form a closed-loop water circulation system for water storage, water supply, and condensed water. Compared with traditional open water supply systems, the water conservation rate is significantly improved and condensed water 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 generating device can be arranged with a low center of gravity, improving the layout stability of the water carrier negative ion generating device. At the same time, it can ensure that the water guide 3012 and the water mist excitation device 302 connected to the auxiliary water tank 3011 can absorb water evenly, which can ensure more stable water mist generation.

[0028] In one embodiment, the negative air ion generating device 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 juxtaposed with the main water tank 3013. This arrangement places the air supply mechanism 203, which provides airflow to the internal airflow channel 201, alongside the main water tank 3013. A rational structural arrangement allows the upper portion of the water carrier negative ion generating device to primarily serve as the intermediate water transfer unit (auxiliary water tank 3011), the middle portion to primarily serve as the output unit for the water carrier negative ion generating structure (internal and external airflow ducts, water mist excitation device 302, mixing chamber 4, negative ion generator 202), and the lower portion to primarily serve as the energy supply unit (water supplied by the main water tank 3013 and air supplied by the air supply mechanism 203). In this manner, the water carrier negative ion output of the water carrier negative ion generating device is primarily located in the center of the device, ensuring aesthetics while preventing the water carrier negative ions from coming too close to the ground, thereby improving output distance and cleanliness. The energy supply unit is arranged at the bottom to ensure a low center of gravity arrangement of the device, while the transfer water supply unit is arranged at the top to reasonably utilize gravity to supply water to the water mist excitation device 302 and ensure the water supply stability of the water mist excitation device 302.

[0029] In one embodiment, the negative ion generator 202 includes a discharge needle and a negative ion discharge needle cleaning device 6; Reference Attachment Figure 13 -Attached Figure 16 , the negative ion discharge needle cleaning device 6 includes a fixed support member 601, a movable support member 602, a linear drive assembly 603 and a cleaning member 604; The fixed support 601 and the discharge needle are arranged in the internal air flow channel 201; the linear drive component 603 is fixedly arranged outside the internal air flow channel 201, and is preferably arranged on the side of the internal air flow 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; further, the cleaning member 604 is provided with a cleaning channel 6041 for the discharge needle to pass through; thus, the movable support 602 is driven by the linear drive assembly 603 to move coaxially relative to the fixed support 601, and then the cleaning member 604 is moved coaxially relative to the installed discharge needle, so that the inner surface of the cleaning channel 6041 is in sliding 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 Attachment Figure 15 -Attached Figure 16According to one embodiment of the present invention, the cleaning member 604 is provided with an elastic cleaning portion 604a; wherein, the cleaning channel 6041 is arranged on the elastic cleaning portion 604a, and the cleaning channel 6041 passes through the body of the elastic cleaning portion 604a.

[0032] Reference Attachment Figure 15 -Attached Figure 16 According to one embodiment of the present invention, the cleaning channel 6041 is a variable diameter channel that changes axially along the cleaning channel 6041. The diameter of the cleaning channel 6041 can be configured to gradually decrease. Thus, the gradually decreasing radial dimension of the cleaning channel 6041 can adapt to the dimensional changes of the outer surface of the discharge needle as it moves 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 and wiping of the outer surface, thereby further enhancing the cleaning effect of the present invention. Furthermore, through 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 cleaning 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. Thus, during the sliding engagement, the cleaning channel 6041 elastically deforms to fully conform to the outer surface of the discharge needle, thereby enhancing the wiping effect and the cleaning effect of the present invention.

[0033] In this embodiment, the elastic cleaning portion 604a is made of a wear-resistant and elastic material such as rubber material, silicone material, etc., so that the cleaning member 604 of the present invention has a long service life and high reliability.

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

[0035] Reference Attachment Figure 3 In one embodiment, the negative air ion generating device 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 shape. In this embodiment, the mixing chamber 4, air supply channel 204, air supply mechanism 203 and main water tank 3013 are closely arranged and compact, while ensuring good air supply and mixing effects.

[0036] Reference Attachment Figure 1 In one embodiment, an air inlet 901 is provided on at least one side of the housing 9 in the direction of the opening 102 ; The air inlet side of the air supply mechanism 203 is disposed correspondingly to the air inlet 901. In this embodiment, the air inlet 901 and the opening 102 for outputting water-carrier negative ions are located on different sides of the device, thereby preventing mutual interference between the two while ensuring both air supply intensity and water-carrier negative ion output intensity. Preferably, two air inlets 901 are provided, and the two air inlets 901 are disposed on opposite side walls of the housing 9. Preferably, the air supply mechanism 203 utilizes a dual-inlet blower, with the two air inlets corresponding to the two air inlets 901, thereby increasing air supply intensity.

[0037] Reference Attachment Figure 4 -Attached Figure 12 In one embodiment, the output components of the negative air 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 negative air ion generator 2 includes an internal airflow channel 201; internal airflow channel 201 forms an internal airflow of negative air ions. 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 can also contain water negative ions, thereby increasing the negative ion content of the water carrier negative ions. An annular outer air flow channel 5 is formed between the housing 1 and the inner air flow channel 201 of the negative air ion generating device 2. The inner part of the annular outer air flow channel 5 is hollow and one end is an outlet end, that is, except for the outlet end, the other positions of the annular outer air flow channel 5 are relatively closed structures, so that the annular outer air flow channel 5 and the inner air flow channel 201 are isolated from each other in the flow direction of the inner air negative ion air flow, thereby preventing water mist from entering the inner air flow 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 portion of the inner air flow channel 201 constitute an annular outer air flow channel 5 surrounding the outer wall of the inner air flow channel 201. It should be noted that the annular outer air flow channel 5 can be an annular structure connected end to end around the inner air flow channel 201, or it can be an arc-shaped structure or a semi-circular structure that is not connected end to end around the inner air flow channel 201. The inner air flow channel 201 and the annular outer air flow channel 5 are separated from each other by the outer wall of the inner air flow channel 201; the water mist generating device 3 is used to generate water mist in the annular outer air flow channel 5; The common outlet end of the annular outer air flow channel 5 and the inner air flow channel 201 in the shell 1 is the mixing chamber 4. Specifically, the end of the inner air flow channel 201 facing the opening 102 is the outlet end, and the outlet end of the annular outer air flow channel 5 located at the outlet of the inner air flow channel 201 is the outlet end, that is, the outlet ends of the annular outer air flow channel 5 and the inner air flow channel 201 are both located on the outlet plane of the inner air flow channel 201. At this time, the other parts of the inner cavity 101 except the annular outer air flow channel 5 and the inner air flow channel 201 are the mixing chamber 4. The mixing chamber 4 is used to mix the inner air negative ion air flow and water mist to form water carrier negative ions; The mixing chamber 4 is used to ensure that the output path of the contained air negative ion air flow is unobstructed, and to cause the water mist flowing after the introduction to generate deflection and / or eddy currents in the mixing chamber 4 to enhance the mixing of the water mist and the contained air negative ion air flow; thereby, the mixing of the contained air negative ion air flow and the water mist is enhanced without directly affecting the output distance of the contained air negative ion air flow; wherein, the water mist generates deflection and / or eddy currents to increase the depth of water mist penetration into the contained air negative ion air flow, improve the mixing effect of the contained air negative ion air flow and the water mist, and ultimately increase the content of negative air ions attached to the water mist. Ensuring that the output path of the contained air negative ion air flow is unobstructed means that any structure in the mixing chamber 4 does not invade the outlet projection range of the outlet direction of the contained air flow channel 201, and does not generate any flow resistance on the physical structure to the contained air negative ion air flow, thereby avoiding reducing the conveying distance of the contained air negative ion air flow. At this time, the structure (mixing enhancement structure) provided in the mixing chamber 4 for guiding the water mist so that it invades the contained air negative ion air flow and the influence of the guided water mist on the conveying distance of the contained air negative ion air flow can be ignored. Moreover, since the water mist is combined with the contained air negative ion air flow, the quality of the air flow is greatly improved. Therefore, not only will the conveying distance of the contained air negative ion air flow not be reduced, but the conveying distance of the water carrier negative ions will be increased due to the formation of water carrier negative ions, thereby ultimately achieving the purpose of increasing the negative ion content while increasing the transmission distance.

[0038] Reference Attachment Figure 6 In specific operation, the negative air ion generating device 2 forms an inner air negative ion airflow in the inner airflow channel 201 and produces an induced jet effect. The inner air negative ion airflow serves as an induced jet flow, which induces the water mist in the annular outer airflow channel 5 to be an induced jet flow. The inner air negative ion airflow induces the water mist in the annular outer airflow channel 5 to flow with the inner air negative ion airflow and completes gas-liquid mixing in the mixing chamber 4 through the mixing enhancement structure. After the gas-liquid mixing, water carrier negative ions (attached Figure 6 The interlaced arrangement of the solid arrows and the hollow solid arrows in the negative ion output port 701 of the water carrier, that is, the water molecule particles with air negative ions in the water mist, are output.

[0039] It should be noted that since the water mist itself contains water negative ions, the water carrier negative ions combine with the negative ions in the airflow containing negative air ions and the water negative ions in the water mist, resulting in a higher negative ion content. Moreover, since 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 avoid localized aggregation of negative ions, ensuring uniform distribution of negative ions in the output airflow.

[0040] The water carrier negative ion generating structure provided by the present invention has the following effects: 1. Utilizing the inner airflow channel 201, the annular outer airflow channel 5, and the mixing chamber 4, the negative ion content of the water carrier is increased while ensuring the transport distance of the water carrier negative ions. This also resolves the conflicting issue in prior art 1 (CN208316022U, a hydrated negative oxygen ion generating device), which sacrifices transport distance for improved mixing efficiency.

[0041] Second, the structural arrangement of the inner air flow channel 201, the annular outer air flow channel 5 and the mixing chamber 4 fully utilizes the space of the inner cavity 101, thereby significantly improving the output distance and negative ion content of negative ions on the basis of a compact structure.

[0042] 3. Due to the design of the internal and external ducts, the water mist can be isolated from the negative ion generator 202 in the air negative ion generating device 2. Combined with the conveying direction of the internal air negative ion airflow of the internal airflow channel 201, the water mist can be completely prevented from entering the internal airflow channel 201 and affecting the service life of the negative ion generator 202, thereby solving the problem that the traditional negative ion generator 202 is easily damaged by moisture.

[0043] 4. The negative air ion generating device 2 forms an internal negative air ion airflow in the internal airflow channel 201, which is used as an output power source for water carrier negative ions and is also used to induce and drive the water mist in the annular external airflow channel 5 to flow, so that the flow of the water mist does not require an independent driving element, reducing the structural complexity and improving the utilization rate of the air supply mechanism 203 in the negative air ion generating device 2.

[0044] 5. The output of water carrier negative ions carries water molecules, which can purify water molecules and control the ambient humidity by adjusting the amount of water mist.

[0045] 6. By arranging water mist in the annular outer air flow channel 5 and arranging the inner air negative ion air flow in the inner air flow channel 201, rather than arranging the inner air negative ion air flow in the annular outer air flow channel 5 and arranging water mist in the inner air flow channel 201, it is possible to avoid the fan supply directly acting on the heavier water mist, resulting in the problem of limited distance for transporting the water carrier.

[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 air flow channel 201; at this time, the function of the water carrier negative ion output port 701 is equivalent to the opening 102 of the housing 1, and at least part of the internal air negative ion air flow output from the internal air flow channel 201 can be directly output to the target position through the water carrier negative ion output port 701 without obstruction (see Appendix Figure 6 (The hollow solid arrow in the figure represents the connotative air negative ion airflow). That is, the diameter of the water carrier negative ion outlet 701 is larger than the inner diameter of the connotative airflow channel 201, but smaller than the outer diameter of the annular outer connotative airflow channel 5. When the exit projection of the connotative airflow channel 201 is within the exit projection of the water carrier negative ion outlet 701, all the connotative air negative ion airflow can be directly and unobstructedly output to the target location through the water carrier negative ion outlet 701, thus avoiding flow resistance to the connotative air negative ion airflow. This not only increases the transport distance of the water carrier negative ions, but also ensures the flow rate and pressure of the connotative air negative ion airflow, thereby ensuring the ejection effect. The mixing chamber 4 is provided with a mixing enhancement structure for enhancing the mixing of the contained air negative ion airflow and the water mist, and the mixing enhancement structure includes a water mist impact surface I 702, which is provided on at least a portion of the wall surface of the housing 1 in the axial extension direction of the annular outer duct airflow channel 5; that is, the outlet end direction of the annular outer duct airflow channel 5 is at least partially not on the water carrier negative ion output port 701; The water mist in the annular outer air flow channel 5 is driven by the injection action (attached Figure 6 At least a portion of the water mist (the solid arrow portion) flows with the contained air negative ion airflow and then strikes the water mist impact surface I 702, causing deflection and diffusion. The deflected water mist is injected into the contained air negative ion airflow, mixed with it, and output from the water carrier negative ion output port 701. This arrangement has the following effects: 1. A portion of the water mist induced by the air negative ion flow will not flow out through the water carrier negative ion output port 701 without obstruction, but will be redirected after hitting the water mist impact surface I 702, and form local turbulence in the redirected part (see Appendix). Figure 6The solid arc arrow part in the middle), and the other part of the water mist moves toward the implied air negative ion air flow, and finally injects into the implied air negative ion air flow for mixing, breaking the original gas-liquid stratified flow, strengthening the gas-liquid two-phase turbulent mixing, making the air negative ions fully contact with the tiny water mist particles, and significantly improving the mixing effect of the implied air negative ion air flow and water mist.

[0047] Second, the diverted water mist will drive the water mist through the water carrier negative ion output port 701 without obstruction (see Figure 6 The solid dotted arrow part in the middle is turned together, thereby achieving a movement trend of all water mist passing through the water carrier negative ion output port 701 to be injected into the contained air negative ion air flow, significantly improving the mixing effect of the contained air negative ion air flow and water mist.

[0048] 3. After the diverted water mist pushes the unobstructed water mist, the unobstructed water mist will be more fully mixed with the negative ion flow of the contained air, and the diverted water mist will decrease in flow rate due to the resistance generated by the diversion and the resistance generated by pushing the unobstructed water mist, forming a local turbulent water mist around the outside of the mixed water carrier negative ions (attached Figure 6 The solid arrow and the solid dotted arrow outside the water carrier negative ion output port 701), and this part of the water mist follows the outside of the water carrier negative ion and moves a certain distance to reduce the escape rate of the negative ions.

[0049] 4. The large-particle water mist generated by the water mist excitation device 302 (large-particle water molecules are inevitably present due to the capacity limitation of the water mist excitation device 302 or the fusion of tiny water molecules) collides with the water mist impact surface Ⅰ702 after being induced by the air flow containing negative ions in the air. After the collision, at least part of the water mist will be broken, reducing the particle size of the large-particle water molecules, refining the water mist, and thereby 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] Exemplarily, the structure of the water mist impact surface I702 of the mixing enhancement structure 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 insufficient mixing; too large an angle will cause backflow to interfere with the induced effect. It can also be a curved surface, which can make the water mist flow smoothly while turning it, reducing the turning resistance. It can also be a structure with flow-around protrusions, grooves or circular holes set on the inclined plane or curved surface, which can cause the water mist to produce deflection and / or vortex. In a preferred embodiment, the water mist impact surface I702 is an inner arc surface structure, and the inner arc surface is formed by transition with the inner side wall of the shell 1, and the center of the inner arc surface structure is located in the mixing chamber 4. At this time, the inner wall of the shell 1 turns after guiding the water mist to move through the inner arc surface structure of the rounded structure. During the turning process, the arc surface structure can reduce the turning resistance and form a Coanda wall to accelerate the flow. Because it is an inner arc surface structure, on the one hand, the volume of the mixing chamber 4 is increased, and on the other hand, the guiding performance can be improved.

[0052] In a preferred embodiment, the surface of the water mist impact surface I 702 is provided with a hydrophobic coating to prevent the water mist from adhering to the water mist impact surface I 702 .

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

[0054] Exemplarily, the cross-section of the internal air flow channel 201 and the water carrier negative ion output port 701 can be rectangular, triangular or other special-shaped structures, and it is only necessary to circulate the internal air negative ion airflow and water carrier negative ions. In a preferred embodiment, the cross-section of the internal air flow channel 201 and the water carrier negative ion output port 701 is circular, which can ensure the area of the internal air flow 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 outlet 701 can be a hole provided in the end wall of the housing 1 or a channel structure. In a preferred embodiment, the water carrier negative ion outlet 701 is a channel structure. Compared to a water carrier negative ion outlet 701 with a hole structure, this arrangement provides stable and smooth flow, rectifying the output of the water carrier negative ions, reducing turbulence, and ultimately slowing the diffusion of the water carrier negative ion jet. Furthermore, the channel allows more time for the gas and liquid phases to mix, improving the mixing effect. Furthermore, the channel maintains the clustering of the water carrier negative ions, providing guidance for the output of the water carrier negative ions and making it easier to control the output direction and speed of the water carrier negative ions. Furthermore, the channel structure cooperates with the water mist impact surface I 702 to re-align the deflected water mist passing through the water mist impact surface I 702, correcting any turbulent flow that deviates. Furthermore, the channel structure cooperates with the mixing chamber 4, so that the strong turbulence within the mixing chamber 4 gradually decays to weak turbulence through boundary layer development at the channel structure entrance, resulting in stable long-distance transport of the water carrier negative ions.

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

[0057] In one embodiment, a grille air guide 704 is provided at the outlet of the water carrier negative ion outlet 701. This grille air guide 704 comprises multiple parallel straight or curved guide vanes (spacing 6.5 mm to 10.5 mm). This divides the outlet water carrier negative ions into multiple jets, forcing the airflow to flow axially and improve the uniformity of the flow field. Furthermore, the grille air guide 704 prevents foreign matter from entering the mixing chamber 4.

[0058] In one embodiment, the mixing enhancement structure further includes a water mist impact surface II 703, which is provided 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 a 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 housing 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, drawn by the ejection action, then flows with the contained air negative ion airflow and strikes the water mist impact surface II 703, causing it to be deflected and diffused. The water mist is then injected into the contained air negative ion airflow, mixed with it, and output from the water carrier negative ion output port 701. In addition to the effects of the water mist impact surface I 702, the water mist impact surface II 703 also forms a guiding slope at the entrance of the water carrier negative ion output port 701, forcing the gas-liquid two-phase mixed airflow to complete flow correction before entering the equal channel structure. Furthermore, it guides the airflow to flow along the wall, providing guidance for the water carrier negative ions.

[0059] Exemplarily, the structure of the water mist impact surface II 703 can be an inclined plane, thereby causing the water mist to be diverted vertically or at an acute angle. The inclination angle is preferably 30°-45°. An angle that is too small will result in insufficient water mist penetration and inadequate mixing; an angle that is too large will cause backflow to interfere with the ejection effect. The 30°-45° angle can form a guide slope at the entrance of the water carrier negative ion output port 701. It can also be a curved surface, or it can be a structure with flow-around protrusions, grooves, or circular holes set on an inclined plane or curved surface to cause the water mist to deflect and / or eddy currents. While diverting the water mist, it allows the water mist to flow smoothly, reducing steering resistance. In one preferred embodiment, the water mist impact surface I 702 is an inner curved surface structure; the water mist impact surface II 703 is an outer curved surface structure tangent to the water mist impact surface I 702. The water mist impact surface I 702 is an inner curved surface structure, so that the water mist naturally diverts along the curved surface after impact, reducing resistance and promoting more uniform diffusion. The outer arc surface structure of the water mist impact surface II 703 is tangent to the inner arc surface structure, which can achieve a smooth flow transition, reduce energy loss, and allow the water mist to mix with the contained air negative ion airflow at a more appropriate angle and speed. The tangent design may reduce flow separation, avoid the formation of dead corners, and improve mixing efficiency. In addition, the outer arc surface structure is tangent to the inner arc surface structure, which can produce a Venturi effect at the entrance of the water carrier negative ion output port 701, thereby increasing the local flow rate. In addition, the water mist impact surface II 703 of the outer arc surface structure is connected to the channel structure entrance of the water carrier negative ion output port 701, so that a more uniform flow field is formed at the channel entrance, reducing turbulence, thereby improving the 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, wherein the air guide 7 includes an annular side wall embedded in the side wall of the housing 1 and an end wall connected to one end of the annular side wall, wherein the end wall corresponds to the outlet direction of the internal air flow channel 201; The water carrier negative ion output port 701, the water mist impact surface I 702, and the water mist impact surface II 703 are arranged on the end wall; by providing the air guide 7, the size of the opening 102 of the housing 1 can be made large enough to facilitate the installation of the air negative ion generating device 2 and the water mist generating device 3, and the air guide 7 can also be set as a detachable structure, thereby realizing the cleaning and maintenance of the water carrier negative ion output port 701, the water mist impact surface I 702, the water mist impact surface II 703, the inner cavity 101, and the internal air flow channel 201; Reference Attachment Figure 5 and attached Figure 9 The bottom of the shell 1 is conical and is used to collect condensed water formed by water mist in the inner cavity 101 and the air guide 7. The bottom of the cone is provided with an overflow outlet 103, which is used to discharge the condensed water. The condensed water can be used for recycling to the water mist generating device 3 or directly discharged as waste water. There is a gap between the bottom of the annular side wall and the bottom of the shell 1. The gap forms an overflow inlet 104, that is, the condensed water flowing to the bottom of the inner cavity 101 directly flows into the overflow outlet 103 due to the conical structure. Preferably, the overflow outlet 103 is connected to the main water tank 3013 and is used to collect the condensed water into the main water tank 3013 for recycling. The condensed water on the annular side wall, 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 all flows from the bottom wall of the annular side wall to the gap, thereby ensuring that all condensed water can flow smoothly to the overflow outlet 103. In this arrangement, the annular side wall of the air guide 7 constitutes the mixing chamber 4, so that the 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 of the mixing chamber 4 (the bottom wall of the annular side wall).

[0061] In one embodiment, the internal air flow channel 201 is a circular channel, the inner diameter of the internal air flow channel 201 is 34mm-38mm, and the outer diameter of the internal air flow 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 air flow channel 201 is coaxial with the central axis of the plane where the length and width of the air guide 7 are located, that is, the left and right sides of the internal air flow channel 201 are at the same distance from the left and right sides of the air guide 7 cavity, and the upper and lower sides are at the same distance from the upper and lower sides of the air guide 7 cavity; and / or The distance between the outlet of the inner air flow channel 201 and the end wall of the air guide 7 is 13.5 mm to 17.5 mm; and / or The water carrier negative ion output port 701 is a uniform cross-section channel structure, the inner diameter of the water carrier negative ion output port 701 is 48mm-52mm, and the length is 23mm-27mm; and / or The water mist impact surface I 702 is an inner arc surface structure, and the diameter of the water mist impact surface I 702 is 22mm-26mm; and / or The water mist impact surface II 703 is an outer arc surface structure, and the diameter of the water mist impact surface II 703 is 21 mm-25 mm.

[0062] By adopting the above technical solution, when the inner air flow channel 201, the negative ion generator 202, the annular outer air flow channel 5 and the water mist generating device 3 are arranged in two groups horizontally, it has been verified through experiments that the amount of negative ions can reach 30,000 / cm at a position 10 meters away from the negative ion output port 701 of the water carrier. 3 Above, specifically, 2m>600,000 / cm 3 , 4m>200,000 cm 3 , 6m>70,000 / cm 3 , 10m>30,000 / cm 3 The distance and content of negative ions delivered are very effective. At the highest setting, the noise level is less than 45 decibels, meeting the needs of quiet use.

[0063] In one embodiment, refer to the attached Figure 9 The water mist generating device 3 includes a water supply device 301 and a water mist excitation device 302, which are interconnected. Preferably, the water supply device 301 utilizes a secondary water tank 3011, wherein the water supply device 301 is used to supply water to the water mist excitation device 302, which is used to generate water mist through vibration. Specifically, the water mist excitation 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. This can reduce the water retention rate at the outlet of the water carrier negative ion output port 701, resulting in a water consumption of 0.12g / min. This reduces the water consumption rate, conserves water resources, and reduces the frequency of water addition. The water mist excitation device 302 is arranged in the annular outer air flow channel 5 to provide water mist for the annular outer air flow channel 5.

[0064] In one embodiment, the water mist output direction of the water mist generating device 3 is set toward the mixing chamber 4, that is, the water mist generated by the vibration of the vibrating plate directly flows slowly toward the mixing chamber 4, thereby improving the ejection effect of the ejection action and reducing the water hanging rate on other side walls of the annular outer air flow channel 5.

[0065] In one embodiment, refer to the attached Figure 10The water mist excitation device 302 is provided with a group on each side of the inner air flow channel 201, thereby increasing the amount of water mist in the annular outer air flow channel 5 to be sufficient and uniform.

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

[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 excitation device 302. By placing the secondary water tank 3011 above the housing 1, water can be transported on the water guide 3012 by gravity, thereby saving a water transport device.

[0068] In one embodiment, refer to the attached 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 air flow channel 201 , so as to provide air flow for the internal air flow channel 201 .

[0069] Exemplarily, the negative ion generator 202 can be arranged at the outlet of the air supply mechanism 203; or be arranged on the air supply channel 204 between the air supply mechanism 203 and the internal air flow channel 201. Preferably, the negative ion generator 202 is arranged in the internal air flow channel 201. With such an arrangement, on the one hand, negative ions can be generated in a high-speed airflow, thereby avoiding the attenuation of negative ions caused by airflow transmission in traditional external negative ion generators. On the other hand, it can also cooperate with high-speed airflow to accelerate the charged particles to separate from the charged particles of the negative ion generator 202. Furthermore, the negative ion generator 202 is arranged in the middle of the internal airflow channel 201 through a grid support. On the one hand, the negative ions can be symmetrically distributed and evenly diffused. On the other hand, the heat of the electrode at the center of the negative ion generator 202 can be evenly dissipated through the annular airflow, thereby solving the heat dissipation problem of the negative ion generator 202.

[0070] In one embodiment, the inner airflow channel 201, negative ion generator 202, annular outer airflow channel 5, and water mist generating device 3 are arranged horizontally in parallel in at least two groups; the annular outer airflow channel 5 can be divided into two groups by a partition 705 arranged in the middle of the inner cavity 101. In this embodiment, the total cavity enclosed by the housing 1 and air guide 7 has a length of 188mm-196mm and a width of 156mm-164mm. 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 air flow channels 201, that is, one air supply mechanism 203 can generate airflow in multiple groups of internal air flow channels 201. This arrangement can double the negative ion content and water mist content under one air supply mechanism 203.

[0072] In one embodiment, a static elimination structure 8 is further provided in the annular side wall of the air guide 7 for grounding the static electricity in the mixing chamber 4 to ensure anti-static protection in the mixing chamber 4 .

[0073] Reference Attachment Figure 17 -Attached Figure 18 In one embodiment, the static elimination structure 8 includes an annular conductive body 801 and a grounding connection cap 802 disposed on the annular conductive body 801; wherein the annular conductive body 801 constitutes the overall shape of the entire static elimination structure 8, so as to achieve matching installation with the corresponding position on the annular side wall of the air guide 7. In this embodiment, the annular conductive body 801 is provided with a through hole penetrating its side wall; the grounding connection cap 802 is provided corresponding to the through hole on the side wall of the annular conductive body 801; in this embodiment, the grounding connection cap 802 is a hollow structure with one end open and the other end closed, and the hollow portion of the grounding connection cap 802 is connected to the through hole. Therefore, the grounding connection cap 802 can be used to conveniently and stably insert the grounding column into the grounding connection cap 802, and further, based on the conduction between the grounding column and the grounding connection cap 802, the static electricity on the annular conductive body 801 can be conducted to the corresponding ground line, thereby achieving the static elimination effect.

[0074] In a preferred embodiment, the annular conductive body 801 is made of a carbon fiber (or carbon powder)-reinforced conductive ABS ring, with a resistance of ≤500 ohms between the two most distant test points. This configuration facilitates static elimination. In this embodiment, the carbon fiber (or carbon powder)-reinforced conductive ABS ring is a readily available material and can be used as long as it meets the aforementioned requirements. Further details are omitted.

[0075] According to one embodiment of the present invention, the static elimination structure 8 of the present invention further includes: a separation support 803; wherein the separation support 803 is a long strip structure, and the opposite ends of the separation support 803 are respectively connected to the two opposite side surfaces of the annular conductive body 801. In this embodiment, the annular conductive body 801 can be set to a symmetrical annular structure, whereby the separation support 803 can be set in the middle position of the annular conductive body 801, and then the annular conductive body 801 set in the middle position can make the conductive path on the annular conductive body 801 appear symmetrical, which is more beneficial to improving the static elimination effect of the present invention. In a specific embodiment, the separation support 803 covers the upper side of the partition 705 of the air guide 7 to ensure the annular conductive covering effect of the two inner cavities 101.

[0076] According to one embodiment of the present invention, two partition supports 803 are arranged at intervals. The two partition supports 803 arranged at intervals can enrich the conduction paths of the present invention, which is more effective in improving the static electricity elimination effect of the present invention. In addition, by setting the two partition supports 803 at intervals, it can be matched with other structures to effectively ensure the connection reliability of the present invention and the reliable maintenance of the external structure of the present invention. In a specific embodiment, when the internal air flow channel 201, the negative ion generator 202, the annular outer air flow channel 5 and the water mist generating device 3 are arranged horizontally in at least two groups, the two partition supports 803 cover both sides of the partition 705 to further improve the annular conductive covering effect of the inner cavity 101.

[0077] According to one embodiment of the present invention, multiple ground connection caps 802 are provided at intervals, and the multiple ground connection caps 802 are arranged at intervals on the annular conductive body 801; accordingly, the multiple ground connection caps 802 are symmetrically arranged on opposite sides of the partition support 803. In this embodiment, the number of ground connection caps 802 can be an even number (for example, 2, 4, etc.). Therefore, by providing multiple ground connection caps 802 and adopting a symmetrical arrangement, the efficiency of the static elimination method of the present invention can be further improved.

[0078] According to one embodiment of the present invention, the annular conductive body 801 , the ground connection cap 802 and the separation support 803 are an integrated integral structural member.

[0079] Through the above arrangement, the overall forming of the static elimination structure 8 can be effectively ensured, thereby fully improving its production efficiency and reducing its production cost.

[0080] According to one embodiment of the present invention, the sidewall of the annular conductive body 801 has a rectangular cross-section. 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 providing the annular conductive body 801 with a certain width in the axial direction. This allows the sidewall of the annular conductive body 801 to have a larger contact area, thereby achieving better electrostatic adsorption in the installation space.

[0081] Preferably, the annular conductive body 801 is arranged at the mixing chamber 4 of the air guide 7 , thereby improving the static electricity treatment effect in the mixing chamber 4 .
