Description

Technical Field

[0001] This invention relates to the field of portable air handling devices, and more particularly to a neck-mounted negative ion generator. Background Technology

[0002] Negative ions have gained widespread recognition for their numerous health benefits, including air purification, improved breathing quality, and enhanced immunity. Against this backdrop, air purifiers have gradually become popular products in the market, especially portable air purifiers, which are increasingly favored by consumers because they can meet people's needs for fresh air in various scenarios.

[0003] To further enhance portability and ease of use, neck-mounted air handling units have emerged. These devices typically feature a lightweight design, allowing users to easily wear them around their necks. The devices continuously provide treated air, effectively improving the air quality of the surrounding environment and providing a relatively fresh air experience for people in various scenarios such as commuting and working.

[0004] However, current neck-mounted air purifiers on the market have many shortcomings. On the one hand, while negative ions are important for air purification and human health, most existing neck-mounted air purifiers cannot generate a stable supply of water negative ions. Compared to ordinary negative ions, water negative ions have unique advantages in air purification and humidification, providing users with a superior air quality experience. Therefore, developing a neck-mounted air purifier capable of generating a stable supply of water negative ions is a top priority.

[0005] On the other hand, existing neck-mounted air handling units have structural and functional design flaws. Taking the Chinese utility model patent "CN214791731U - Wearable Air Handling Device" as an example, such devices typically rely on airflow and water mist to regulate air humidity. The water mist generated by its humidification module passes through a fan, and the negative ion generator is also positioned in the path of the water mist. This design inevitably leads to water mist corroding the relevant electrical and mechanical components during operation. Over time, this severely impacts the overall performance of the device and significantly reduces its durability, increasing user costs, affecting user experience, and limiting the further development of neck-mounted air handling units. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a neck-hanging water negative ion generator.

[0007] To achieve the above-mentioned objectives, the present invention provides a neck-hanging water negative ion generator, comprising: a generator housing for easy neck hanging, a water negative ion generating unit, a fan unit, a power supply unit, and a control unit disposed within the generator housing; The control unit is electrically connected to the water negative ion generating unit and the fan unit, respectively. The power supply unit is electrically connected to the control unit, the water negative ion generating unit, and the fan unit, respectively; The generator housing has two opposing free ends, and the fan unit is respectively arranged in the two free ends, with the two fan units arranged opposite to each other; At least one water negative ion generating unit shall be provided; The upper side of the free end is provided with a first opening for the fan unit to output air and a second opening for the water negative ion generating unit to output water negative ions. The first opening and the second opening are arranged in at least one of the following ways: they are arranged side by side along the extension direction of the free end, side by side along the width direction of the free end, and at least partially overlap. The water negative ion generating unit is used to generate water negative ion water mist; The fan units arranged opposite each other are used to form opposing air curtains to promote the distribution and retention of the water negative ion mist between the opposing air curtains.

[0008] According to one aspect of the invention, the two free ends of the generator housing both extend in the horizontal direction in a direction that approaches each other; Both free ends of the generator housing extend in a downward tilting direction in the vertical direction.

[0009] According to one aspect of the invention, the first opening is provided with a plurality of first segmented members arranged at intervals in the extending direction of the free end; The first segment is a curved structural component; The outer end of the first segment bends away from the free end.

[0010] According to one aspect of the present invention, the water negative ion generating unit comprises: a generating unit housing, a generating unit cover, a vibrating friction plate, and a water pump; The generating unit housing includes: a water storage chamber, an atomizing chamber, and a water return chamber; A negative water ion outlet is provided on the upper side of the atomizing chamber; The water storage chamber is equipped with a water inlet; The water storage chamber and the atomizing chamber are arranged sequentially along the extension direction of the free end; The water return chamber is located below the atomizing chamber; A first partition is provided between the water storage chamber and the atomizing chamber, and the first partition has a first water passage hole; A second partition is provided between the atomizing chamber and the return water chamber, and the second partition has a first return water hole; The vibrating friction plate is disposed in the atomizing chamber, and the water inlet side of the vibrating friction plate is connected to the first water passage hole; The water inlet of the water pump is connected to the return water chamber, and the water outlet of the water pump is connected to the water storage chamber.

[0011] According to one aspect of the invention, the generating unit cover includes: a cover support and a first closing cover; The cover support is provided with a first transition hole; The first transition hole is connected to the second opening and the negative water ion outlet, respectively; The first transition hole is provided with a plurality of second dividing pieces arranged at intervals in the extending direction of the free end; The second segment is a curved structural component; The outer end of the second segment bends away from the free end.

[0012] According to one aspect of the invention, at least one of the second segment members is provided with a baffle blade on its lower side; The partition blade is a curved blade, and the curvature direction of the cross-section of the partition blade is consistent with the curvature direction of the second segment. The lower end of the partition blade is spaced apart from the second partition plate.

[0013] According to one aspect of the invention, the distance between the baffle blade and the front side plate of the atomizing chamber is less than the distance between the baffle blade and the first baffle.

[0014] According to one aspect of the invention, the thickness of the partition blade is configured to gradually decrease from the connecting end toward the second partition.

[0015] According to one aspect of the present invention, the fan unit includes: a centrifugal fan and an air guide structure connected to the fan outlet of the centrifugal fan; The air guiding structure includes: an air outlet cavity and an air inlet cavity; Along the width direction of the free end, the air outlet cavity and the air inlet cavity are arranged side by side, and the air outlet cavity and the air inlet cavity are connected to each other; An air outlet is provided on the upper side of the air outlet cavity, and a fan connection port is provided on the lower side of the air inlet cavity; The air outlet is connected to the first opening; The fan interface is connected to the air outlet of the centrifugal fan.

[0016] According to one aspect of the invention, it further includes: a negative ion generator; The negative ion generator is electrically connected to the power supply unit and the control unit; The negative ion generator is installed at the bottom of the air outlet cavity.

[0017] According to one aspect of the present invention, by setting the outlets of the water negative ion generating unit and the fan unit respectively, the present invention can physically isolate the mist output path of the water negative ion generating unit and the air output path of the fan unit, thereby effectively avoiding the influence and erosion of the water negative ion mist on the circuit structure, and thus effectively ensuring the reliability and service life of the present invention.

[0018] According to one aspect of the present invention, by separately configuring the outlets of the water negative ion generating unit and the fan unit, the arrangement of the outlets offers greater flexibility. Specifically, by separately configuring the mist outlet path and air outlet path of the water negative ion generating unit and the fan unit, flexible arrangement of the outlet positions can be achieved, greatly increasing the versatility of the design combination and effectively improving the performance of the invention. Furthermore, the independently designed mist outlet path of the water negative ion generating unit allows the outlet to be led to different locations on the generator housing, such as two opposite free ends, significantly improving the scalability of the water negative ion outlet position design.

[0019] According to one aspect of the present invention, the first segment, bent in a direction away from the free end, effectively guides the airflow direction of the output natural wind, allowing it to flow to the designated target area as intended when passing through the air outlet. This facilitates a more uniform distribution of the generated negative water ion mist within the target area. Furthermore, the degree of bending of the first segment can further deflect and guide the airflow direction, effectively preventing the airflow from impacting the target area and creating a gentler air curtain, which is beneficial for improving the effectiveness of the invention. Moreover, the deflected airflow can draw the carried negative water ion mist inward, resulting in a longer retention time during the uniform distribution of the negative water ion mist.

[0020] According to one aspect of the present invention, the flow direction of the output water mist of negative water ions can be effectively guided by the second dividing member, which is bent in a direction away from the free end. This allows the water mist of negative water ions to flow to the air curtain area output by the first opening as intended when passing through the first transition hole, thereby allowing the negative water ions to be dispersed by natural wind. Furthermore, the second dividing member can be flexibly bent to further guide the deflection of the water mist flow direction, thereby making it easier and more accurate to introduce negative water ions into the air curtain area output by the first opening, which is more beneficial to improving the effectiveness of the present invention. According to one aspect of the present invention, by setting baffle blades in the atomizing chamber, a guiding effect is formed in the atomizing chamber to achieve the generation of negative water ion mist, so that most of the mist can be output from most of the openings of the first transition hole corresponding to the baffle blade and the first partition. Furthermore, by setting the baffle blades as curved blades, the mist flow can be deflected based on the curved surface of the baffle blades during the process of being blocked and turned, so that the deflection effect of the negative water ion mist during the output process is further enhanced, thereby making it easier for the negative water ion mist to be transported to a farther position after output to achieve matching and mixing with the air curtain formed by the first opening, which greatly improves the transmission and distribution effect of negative water ions of the present invention.

[0021] According to one aspect of the present invention, the baffle blade allows a portion of the negative water ion mist to be delivered through a small-area channel formed between the baffle blade and the surrounding wall to the wall between the baffle blade and the atomizing chamber. This causes the negative water ion mist to be output from a small opening of the first transition hole corresponding to the wall between the baffle blade and the atomizing chamber. As a result, the output of the negative water ion mist exhibits a relative difference, which is more beneficial to the overall expansion and distribution of the mist output through the second opening. In particular, near the first opening, this differentiated output of negative water ion mist can be more easily drawn into the natural wind output from the first opening, which is more beneficial to improving the distribution effect of the present invention.

Detailed Implementation

[0023] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the embodiments will be briefly described below. Obviously, the drawings described below are merely some embodiments of the present invention, and those skilled in the art can obtain other drawings based on these drawings without creative effort.

[0024] In describing embodiments of the present invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" express orientations or positional relationships based on the orientations or positional relationships shown in the relevant drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present invention.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described in detail here, but the embodiments of the present invention are not limited to the following embodiments.

[0026] Combination Figure 1 , Figure 2 and Figure 3As shown, according to one embodiment of the present invention, a neck-hanging water negative ion generator includes: a generator housing 1 for easy neck hanging, a water negative ion generating unit 2, a fan unit 3, a power supply unit 4, and a control unit 5 disposed within the generator housing 1. In this embodiment, the shape of the generator housing 1 determines the overall shape of the neck-hanging water negative ion generator, and it serves as the main supporting structure of the entire neck-hanging water negative ion generator. The generator housing 1 is a hollow structure to facilitate the installation and arrangement of the water negative ion generating unit 2, the fan unit 3, the power supply unit 4, and the control unit 5. Thus, the control unit 5 is electrically connected to the water negative ion generating unit 2 and the fan unit 3 respectively; the power supply unit 4 is electrically connected to the control unit 5, the water negative ion generating unit 2, and the fan unit 3 respectively; the power supply unit 4 provides operating power to the control unit 5, the water negative ion generating unit 2, and the fan unit 3 respectively, and the control unit 5 controls the operation of the water negative ion generating unit 2 and the fan unit 3 respectively.

[0027] In this embodiment, to facilitate the implementation of the neck-hanging method of the present invention, the generator housing 1 is generally open-ring shaped, i.e., U-shaped structure; thus, the generator housing 1 has two opposite free ends, and fan units 3 are respectively arranged in the two free ends, so that the two fan units 3 are arranged in a opposite manner; in this embodiment, by arranging fan units 3 in the two opposite free ends, an air curtain is generated at the opposite position, providing a stable and reliable distribution and residence environment for the water negative ion mist generated by the water negative ion generating unit 2.

[0028] In this embodiment, at least one negative water ion generating unit 2 is provided to generate negative water ion mist; wherein, see Figure 1 Taking a single negative ion generating unit 2 as an example, it can be arranged adjacent to one of the fan units 3, with the negative ion generating unit 2 and the fan unit 3 arranged side by side along the direction of their free ends. Through the adjacent arrangement of the negative ion generating unit 2 and the fan unit 3, the negative ion mist generated by the negative ion generating unit 2 can be easily mixed with the air curtain generated by the nearby fan unit 3. Driven by the air curtain, the mist is then carried to the target area. Correspondingly, since the opposing fan unit 3 also generates its own air curtain, it effectively intercepts the blown negative ion mist. Furthermore, the interaction between the opposing air curtains allows the negative ion mist to continuously circulate between them, achieving uniform distribution and retention between the two air curtains. In addition, the effect of the opposing air curtains effectively suppresses the settling velocity of the negative ion mist under gravity, thus achieving a long-term retention effect.

[0029] In this embodiment, a first opening 1a for supplying negative water ions to the negative water ion generating unit 2 and a second opening 1b for supplying air to the fan unit 3 are provided on the upper side of the free end. In this embodiment, the first opening 1a and the second opening 1b are arranged side by side along the extension direction of the free end. The first opening 1a starts from the end of the free end and extends away from the end face of the free end. Correspondingly, the second opening 1b starts from the position adjacent to the first opening 1a and extends away from the first opening 1a. In this embodiment, the openings of the first opening 1a and the second opening 1b can be set to be the same or different. The extension lengths of the first opening 1a and the second opening 1b can be set according to actual conditions, thereby achieving matching control of the output water ion mist and the output air volume at the two opening positions, so as to facilitate the mixing effect at the two opening positions. Furthermore, in order to achieve the distribution range of the natural wind output at the first opening 1a, the first opening 1a can be made to start from the end face of the free end or the corner of the end face, thereby realizing the output of air volume at the corner of the free end, which fully improves the coverage range of the output air curtain.

[0030] In another embodiment, the first opening 1a and the second opening 1b can be arranged side by side along the width direction of the free end. The second opening 1b and the first opening 1a are arranged sequentially from the inside to the outside along the width direction of the free end. Thus, the natural wind output from the first opening 1a can surround the water negative ion mist output from the second opening 1b, thereby more conveniently dispersing the water negative ion mist and facilitating its transport between the two opposing wind curtains, resulting in a more sufficient distribution of water negative ions.

[0031] In another embodiment, the first opening 1a and the second opening 1b are at least partially overlapped, for example, the first opening 1a and the second opening 1b are partially overlapped along the extension direction of the free end, or the first opening 1a and the second opening 1b are partially overlapped along the width direction of the free end; thereby, mixing can be achieved between the air outlet and the water mist outlet, so as to achieve a more sufficient and convenient uniform distribution.

[0032] In another embodiment, the first opening 1a and the second opening 1b can be arranged in parallel along the extension direction of the free end, arranged in parallel along the width direction of the free end, or arranged in combination in two or three ways, with at least partial overlap. The first opening 1a and the second opening 1b can each be set as multiple parts, and each part adopts a different arrangement to achieve a combination of multiple arrangement methods, thereby flexibly realizing different mixing effects of the output natural wind and water negative ion mist, so as to make the use effect of the present invention better. In this embodiment, in order to facilitate the corresponding arrangement, the internal conveying pipeline can be flexibly set to adapt to the corresponding arrangement flexibility.

[0033] By setting the above configuration, the present invention can physically isolate the mist output path of the water negative ion generating unit 2 and the air output path of the fan unit 3 by setting the outlets of the water negative ion generating unit 2 and the fan unit 3 respectively. This can effectively avoid the influence and erosion of the circuit structure by the water negative ion mist, and thus effectively ensure the reliability and service life of the present invention.

[0034] Furthermore, by separately configuring the outlets of the water negative ion generating unit 2 and the fan unit 3, this invention offers greater flexibility in outlet arrangement. Specifically, by separately configuring the mist exit path and air exit path of the water negative ion generating unit 2 and the fan unit 3, flexible arrangement of the outlet positions can be achieved, greatly increasing the versatility of the design combination and effectively improving the performance of the invention. Moreover, the independently designed mist exit path of the water negative ion generating unit 2 allows the outlet to be led to different locations on the generator housing 1, such as two opposite free ends, significantly improving the scalability of the water negative ion outlet position design.

[0035] Furthermore, the water negative ion generating unit 2 of the present invention can be arranged on at least one free end of the generator housing 1, which further effectively increases the flexibility of the arrangement of the water negative ion generating unit 2 and can fully guarantee the performance of the present invention.

[0036] Combination Figure 1 and Figure 4 As shown, according to one embodiment of the present invention, the generator housing 1 has a symmetrical structure and includes: a central connecting portion 11, a first support arm 12, and a second support arm 13. The hollow connecting portion 11 is a hollow, curved tubular structure with open ends at both opposite ends, allowing the first support arm 12 and the second support arm 13 to be installed at their respective ends. In this embodiment, the first support arm 12 and the second support arm 13 are detachably installed with the central connecting portion 11. Furthermore, to facilitate the use of the generator housing 1, the central connecting portion 11 can be configured as an elastic structure. Thus, during wear, applying forces in opposite directions to the first support arm 12 and the second support arm 13 increases the opening width for easier wearing. After wearing, releasing the first support arm 12 and the second support arm 13 allows the central connecting portion 11 to elastically return to its original position, ensuring the generator housing 1 is reliably worn around the neck.

[0037] In this embodiment, the first support arm 12 and the second support arm 13 are both hollow tubular structures. The first support arm 12 and the second support arm 13 are both provided with open ends to realize the fitting and locking with the end of the intermediate connecting part 11, while the other end of the first support arm 12 and the second support arm 13 forms a corresponding free end.

[0038] like Figure 2 As shown, according to one embodiment of the present invention, the intermediate connecting portion 11 includes: a tubular body 111, a first connecting member 112, and a second connecting member 113; wherein, the tubular body 111 constitutes the entire curved main structure to achieve corresponding ease of use based on its elasticity. In this embodiment, to ensure that the tubular body 111 has sufficient structural strength and elasticity, ribs made of the same material as the tubular body 111 may be further provided on the tubular body 111, wherein, along the vertical direction, the ribs are located at the middle position of the tubular body 111, and the two sides of the ribs in the width direction are respectively fixedly connected to the opposite sides of the tubular body 111 in the horizontal direction. Of course, the ribs can be one or multiple spaced apart, which will not be elaborated here.

[0039] In this embodiment, multiple contact protrusions are regularly arranged on the side of the tubular body 111, with adjacent contact protrusions spaced apart. When the neckband-style water negative ion generator of the present invention is worn, the contact protrusions form dispersed contact with the skin, avoiding full-surface contact between the tubular body 111 and the skin, thereby improving the breathability and wearing comfort at the wearing position. In addition, the water negative ion generating unit 2, fan unit 3, power supply unit 4, and control unit 5 are distributed in the first support arm 12 and the second support arm 13, making the mass distribution of the neckband-style water negative ion generator of the present invention more reasonable, which is conducive to achieving stable contact between the contact protrusions and the skin when worn. Furthermore, based on the slight vibration of the water negative ion generating unit 2 and fan unit 3 during operation, as well as the vibration generated by the user's movement, the contact protrusions can generate varying contact stress at the contact position, reducing wearing fatigue and improving the user experience.

[0040] In this embodiment, the first connector 112 and the second connector 113 have identical structures, and both are rigid structural components with a material hardness greater than that of the tubular body 111 to ensure reliable and stable connection. Therefore, it includes a connector body a1 and a connector rib a2. The connector body a1 has an annular structure with an annular protrusion at its end. An annular groove matching the annular protrusion is provided on the inner side of the end of the tubular body 111 to facilitate the fitting connection between the connector body a1 and the tubular body 111. To ensure a stable and reliable connection, adhesive can be applied at the fitting position for bonding. Furthermore, the connector rib a2 is located inside the connector body a1, vertically positioned in the middle. The two sides of the connector rib a2 in the width direction are fixedly connected to the opposite sides of the connector body a1 in the horizontal direction to ensure the structural stability and reliability of the connector body a1.

[0041] In this embodiment, a positioning mounting hole may also be provided on the connector body a1, and the axial direction of the positioning mounting hole is arranged horizontally. Therefore, by providing a positioning pin inside the open end of the first support arm 12 or the second support arm 13, which passes through the positioning mounting hole, the connector body a1 can be positioned and installed with the open end of the first support arm 12 or the second support arm 13. Furthermore, the locking action of a threaded connector can lock the first support arm 12 or the second support arm 13 to the connector body a1, ensuring the convenience and reliability of the connection.

[0042] Furthermore, along the horizontal direction, a fitting positioning groove can be provided on the side of the connector body a1, and the position of the fitting positioning groove corresponds to the position mounting hole of the connector body a1. Thus, the interior of the opening end of the first support arm 12 and the second support arm 13 can be further provided with a fitting positioning protrusion that cooperates with the fitting positioning groove, and the position of the fitting positioning protrusion corresponds to the position of the positioning post. Therefore, when the positioning mounting hole is inserted into the interior positioning post of the opening end of the first support arm 12 or the second support arm 13, the corresponding fitting positioning groove and fitting positioning protrusion can be matched to further achieve reliable and stable installation.

[0043] like Figure 4As shown, according to one embodiment of the present invention, the first support arm 12 includes: a first support arm body 121 and a first support arm cover 122; wherein, the first support arm body 121 and the first support arm cover 122 are provided with a snap-fit ​​structure (i.e., a snap-fit ​​structure in which a buckle and a slot cooperate) at their edges; further, a positioning post for matching the positioning mounting hole on the connector body a1 can be provided on the inner side of the first support arm body 121, and a threaded connecting post is provided on the inner side of the first support arm cover 122, and the threaded connecting post and the positioning post can be nested together for installation; further, to facilitate the installation of the threaded connector and the threaded connecting post, the positioning post can be hollow and an opening can be formed on the side of the first support arm body 121 to facilitate the threaded connector to pass through the positioning post to lock with the threaded connecting post, thereby achieving structural stability of the first support arm 12. In addition, to further ensure the continuous smoothness of the surface where the threaded connector is located, a first fastening member 123 can be further provided.

[0044] In this embodiment, a first filter mounting cavity 1211 protruding inward is provided below the first opening 1a of the first support arm body 121. This allows for convenient placement of a filter and a fan unit 3 on opposite sides of the first filter mounting cavity 1211. Furthermore, to seal the first filter mounting cavity 1211, a first filter cavity cover 124 is provided to facilitate the replacement of the installed filter. In this embodiment, the first filter cavity cover 124 has a perforated pattern to form an air entry channel.

[0045] In this embodiment, in order to facilitate the fan unit 3 to draw in enough air, an opening is provided on the wall of the first filter mounting cavity 1211 at a position corresponding to the fan unit 3, so that air can be drawn in by the fan unit 3 through the filter and discharged from the first opening 1a.

[0046] like Figure 4As shown, according to one embodiment of the present invention, the second support arm 13 includes: a second support arm body 131 and a second support arm cover 132; wherein, the second support arm body 131 and the second support arm cover 132 are provided with a snap-fit ​​structure (i.e., a snap-fit ​​structure in which a buckle and a slot cooperate) at their edges; further, a positioning post for matching the positioning mounting hole on the connector body a1 can be provided on the inner side of the second support arm body 131, and a threaded connecting post is provided on the inner side of the second support arm cover 132, and the threaded connecting post and the positioning post can be nested together for installation; further, to facilitate the installation of the threaded connector and the threaded connecting post, the positioning post can be hollow and an opening can be formed on the side of the second support arm body 131 to facilitate the threaded connector to pass through the positioning post to lock with the threaded connecting post, thereby achieving structural stability of the second support arm 13. In addition, to further ensure the continuous smoothness of the surface where the threaded connector is located, a second fastening member 133 can be further provided.

[0047] In this embodiment, the second support arm body 131 has an inwardly protruding second filter mounting cavity 1311 below the first opening 1a. This allows for convenient mounting of a filter and a fan unit 3 on opposite sides of the second filter mounting cavity 1311. Furthermore, to seal the second filter mounting cavity 1311, a second filter cavity cover 134 is provided to facilitate the replacement of the installed filter. In this embodiment, the second filter cavity cover 134 has a perforated pattern to form a channel for air entry.

[0048] In this embodiment, in order to facilitate the fan unit 3 to draw in enough air, an opening is provided on the wall of the second filter mounting cavity 1311 at a position corresponding to the fan unit 3, so that air can be drawn in by the fan unit 3 through the filter and discharged from the first opening 1a.

[0049] According to one embodiment of the present invention, the two free ends of the generator housing 1 extend in the horizontal direction in a direction that approaches each other, see [reference needed]. Figure 1 Therefore, when the generator housing 1 is in a free state, the opening of the generator housing 1 can be effectively reduced to ensure reliable wear. In this embodiment, the two free ends are curved to extend closer to each other; thus, the extension directions of the first opening 1a and the second opening 1b arranged on the generator housing 1 match the extension directions of the free ends. As a result, the blown air curtain and water negative ion mist are more easily adapted to the user's facial shape, achieving accurate distribution of the air curtain and water negative ions around the face.

[0050] Furthermore, both free ends of the generator housing 1 extend downwards in the vertical direction, see [reference needed]. Figure 3 By extending the free end at a downward angle, the first opening 1a and the second opening 1b are positioned at an upward angle. This ensures that the emitted water mist containing negative ions and natural wind are accurately distributed in the target area in front of the user's mouth and nose. In this embodiment, the free end extends downward from the point where the generator housing 1 contacts the user's shoulder. This positions the first opening 1a and the second opening 1b directly below the user's face, allowing for more accurate distribution of the water mist containing negative ions and natural wind emitted at an upward angle based on the first opening 1a and the second opening 1b in front of the user's face. Furthermore, by bringing the first opening 1a closer to the end of the free end, the air curtain continuously output from the first opening 1a is positioned below the water mist containing negative ions output from the second opening 1b, effectively catching the water mist containing negative ions and achieving thorough mixing and prolonged retention of the water mist containing negative ions.

[0051] like Figure 4 As shown, according to one embodiment of the present invention, a first opening 1a is provided with a plurality of first segmented members 1a1 arranged at intervals in the extending direction of the free end; wherein, the first segmented members 1a1 are curved structural members; for example, the first segmented members 1a1 can be configured as curved plate-shaped structural members or curved strip-shaped structural members. Further, in the first opening 1a, the first segmented members 1a1 are bent in a direction away from the free end, and the outer end of the first segmented members 1a1 is bent in a direction away from the free end; specifically, along the width direction of the free end, the distance between the end of the first segmented member 1a1 facing the inside of the generator housing 1 and the end face of the free end is smaller than the distance between the other end of the first segmented member 1a1 and the end face of the free end.

[0052] Through the above configuration, the first segment 1a1, bent in a direction away from the free end, effectively guides the airflow direction of the output natural wind. This allows the natural wind to flow to the target area as intended when passing through the air outlet, thus facilitating the uniform distribution of the generated negative water ion mist in the target area. Furthermore, by adjusting the degree of bending of the first segment 1a1, the airflow direction can be further deflected and guided, effectively preventing the airflow from impacting the target area and resulting in a gentler air curtain, which is more beneficial to improving the effectiveness of the invention. Moreover, the deflected airflow can gather the negative water ion mist diagonally upwards towards the face, further increasing the air curtain's catchment area for the negative water ion mist, thereby achieving a longer-lasting retention effect during the uniform distribution of the negative water ion mist.

[0053] Furthermore, by adjusting the thickness of the first dividing member 1a1, the first opening 1a can be divided. This allows for the blocking of the output airflow at the position of the first dividing member 1a1, further enabling flexible suppression of airflow impact. Moreover, the airflow passing through the first dividing member 1a1 can be further merged, resulting in better overall blowing smoothness.

[0054] In this embodiment, since the structure of the generator housing 1 is symmetrical, the first segment 1a1 on the free end set at the symmetrical position can present a corresponding symmetrical distribution. Thus, the wind curtains formed at relative positions can have basically the same characteristics, so as to fully realize the uniform distribution and long-term retention of water negative ion mist under the gentle blowing effect.

[0055] Combination Figure 1 , Figure 3 and Figure 5 As shown, according to one embodiment of the present invention, the water negative ion generating unit 2 includes: a generating unit housing 21, a generating unit cover 22, a vibrating friction plate 23, and a water pump 24; wherein, the generating unit housing 21 is generally hollow to achieve the effect of water storage and atomization to generate water negative ion mist, and its compact structure and small size greatly facilitate the integrated installation of the water negative ion generating unit 2 in the generator housing 1. In this embodiment, the generating unit housing 21 includes: a water storage chamber 211, an atomization chamber 212, and a return water chamber 213; wherein, a water negative ion outlet 212a is provided on the upper side of the atomization chamber 212; a water inlet 211a is provided on the water storage chamber 211; furthermore, along the extension direction of the free end, the water storage chamber 211 is provided on the rear side of the atomization chamber 212; and the return water chamber 213 is provided on the lower side of the atomization chamber 212. In this embodiment, to facilitate the separation of each chamber, a first partition 214 is provided between the water storage chamber 211 and the atomizing chamber 212, and the first partition 214 has a first water passage hole 214a; a second partition 215 is provided between the atomizing chamber 212 and the return water chamber 213, and the second partition 215 has a first return water hole 215a.

[0056] Furthermore, to facilitate the generation of negative water ion mist in the atomizing chamber 212, a vibrating friction plate 23 is correspondingly disposed in the atomizing chamber 212, and the water inlet side of the vibrating friction plate 23 is connected to the first water passage hole 214a. In this embodiment, the vibrating friction plate 23 can be implemented using existing mature friction plates, which will not be described in detail here.

[0057] Furthermore, to facilitate the recovery of condensed water in the atomizing chamber 212, the inlet of the water pump 24 is connected to the return water chamber 213, and the outlet of the water pump 24 is connected to the storage chamber 211. Thus, the condensed water is recovered into the return water chamber 213 through the first return water hole 215a. A connecting pipe can be installed at the bottom of the return water chamber 213 to connect to the inlet of the water pump 24, allowing the recovered water to be drawn out. Similarly, a connecting pipe is also installed between the outlet of the water pump 24 and the storage chamber 211 to output the drawn water. In this embodiment, the water pump 24 can be configured as a diaphragm pump to fully ensure the small size of the invention. Moreover, the water pump 24 can be directly fixedly installed at the bottom of the storage chamber 211 due to its small size, further achieving high integration and small size of the water negative ion generating unit 2.

[0058] like Figure 2 As shown, according to one embodiment of the present invention, the generating unit housing 21 is assembled by welding or bonding the water tank body 21a and the water tank side cover 21b together. The water tank body 21a is configured based on the structural design and distribution of the water storage chamber 211, the atomizing chamber 212, and the return water chamber 213. Specifically, the water tank body 21a has side plates and an annular enclosure surrounding the side plates, while the first partition 214 and the second partition 215 are correspondingly arranged and connected within the side plates and the annular enclosure, thereby dividing the corresponding water storage chamber 211, atomizing chamber 212, and return water chamber 213. In this embodiment, the side plates, the annular enclosure, the first partition 214, and the second partition 215 in the water tank body 21a are integrally formed. Furthermore, the shape of the water tank side cover 21b is matched with the shape of the water tank body 21a. Thus, the entire generating unit housing 21 can be constructed by fastening the water tank side cover 21b to the water tank body 21a and by welding or bonding.

[0059] In this embodiment, the negative ion outlet 212a is located on the upper side of the annular enclosure of the water tank body 21a to achieve communication with the atomizing chamber 212. The second partition 215 is located below the negative ion outlet 212a, and the second partition 215 includes a first plate-shaped portion, a transition portion, and a second plate-shaped portion. From the first partition 214 to the front sidewall of the atomizing chamber 212, the first plate-shaped portion, the transition portion, and the second plate-shaped portion are connected in sequence. The first plate-shaped portion is arranged parallel to the lower sidewall of the return water chamber 213, and the transition portion is an arc-shaped plate that bends towards the upper side of the atomizing chamber 212. Correspondingly, the second plate-shaped portion is connected to the end of the transition portion and the front sidewall of the atomizing chamber 212, so that the second plate-shaped portion is in an upward-curving state.

[0060] In this embodiment, a linear groove or linear hole is provided on the first plate-shaped portion for embedding the lower end of the vibrating friction plate 23. This allows for the limited installation of the lower end of the vibrating friction plate 23. Correspondingly, the upper end of the vibrating friction plate 23 is connected to the first partition plate 214 via a threaded connector, ensuring that the water inlet end of the vibrating friction plate 23 can accurately and tightly align with the first water passage hole 214a. In this embodiment, sealing gaskets or other sealing structures can be further provided around the water inlet end of the vibrating friction plate 23 and the first water passage hole 214a to ensure reliable water input from the water storage chamber 211 to the vibrating friction plate 23, effectively preventing water leakage.

[0061] In this embodiment, the first return water hole 215a can be configured as a linear hole, which can start from the first plate-shaped portion and terminate at the end of the second plate-shaped portion. This ensures that the first return water hole 215a has sufficient length to achieve full recovery of condensate. In this embodiment, to reduce the processing difficulty of the first return water hole 215a, it can be positioned at the connection between the second partition 215 and the water tank side cover 21b. Specifically, a groove matching the shape of the first return water hole 215a can be machined on the side of the second partition 215. After the water tank body 21a and the water tank side cover 21b are fixedly connected, the first return water hole 215a can be formed.

[0062] Through the above-described design, the present invention effectively increases the opening area of ​​the elongated first return water hole 215a, enabling full recovery of condensate over a large area. Furthermore, by setting the second baffle 215 to a partially curved structure, and considering the overall structure of the generator housing 1 and its downward tilt during wear, condensate can more easily flow along the first return water hole 215a and return to the lower return water chamber 213, making the water return process of the present invention easier.

[0063] In this embodiment, to facilitate timely viewing of the water level in the water storage chamber 211, a transparent window can be provided on the main body 21a of the water tank. Correspondingly, to facilitate timely viewing by the user, a corresponding opening can be provided on the generator housing 1.

[0064] Combination Figure 1 , Figure 2 and Figure 6As shown, according to one embodiment of the present invention, the generator unit cover 22 includes: a cover support 221 and a first sealing cover 222; wherein, the cover support 221 is provided with a first transition hole 221a; the first transition hole 221a is connected to a second opening 1b and a water negative ion outlet 212a respectively; further, the first transition hole 221a is provided with a plurality of second dividing members 1b1 arranged at intervals in the extending direction of the free end; in this embodiment, the second dividing members 1b1 are curved structural members; for example, the second dividing members 1b1 can be configured as curved plate-shaped structural members or curved strip-shaped structural members. Further, in the first transition hole 221a, the second dividing members 1b1 are bent in a direction away from the free end, and the outer end of the second dividing members 1b1 is bent in a direction away from the free end; specifically, along the width direction of the free end, the distance between the end of the second dividing member 1b1 facing the inside of the generator housing 1 and the end face of the free end is smaller than the distance between the other end of the second dividing member 1b1 and the end face of the free end.

[0065] With the above configuration, the flow direction of the output water mist of negative ions can be effectively guided by the second dividing member 1b1, which is bent in the direction away from the free end. This allows the water mist of negative ions to flow to the air curtain area output by the first opening 1a as designed when passing through the first transition hole 221a, thereby allowing the water negative ions to be dispersed by natural wind. Furthermore, the second dividing member 1b1 can be flexibly bent to further deflect and guide the flow direction of the water mist, so that the water mist of negative ions is distributed obliquely upward towards the facial area. As a result, when it falls under the action of gravity, it can be more conveniently and accurately introduced into the air curtain area output by the first opening 1a, which is more beneficial to improving the use effect of the present invention.

[0066] Furthermore, by adjusting the thickness of the second dividing member 1b1, the first transition hole 221a can be divided. This allows for the blocking of the output water mist at the position of the second dividing member 1b1, further enabling flexible suppression of the water mist flow speed. Moreover, the water mist passing through the second dividing member 1b1 can further converge, resulting in a more widespread dispersion effect.

[0067] Combination Figure 6 and Figure 7 As shown, according to one embodiment of the present invention, the lower end of the second dividing member 1b1 is flush with the lower side of the cover support 221, while the upper end of the second dividing member 1b1 is spaced apart from the upper side of the cover support 221, thereby forming a groove-like structure between the upper end of the second dividing member 1b1 and the upper side of the cover support 221, which facilitates the insertion of the first sealing cover 222.

[0068] See Figure 6As shown, in this embodiment, the first sealing cap 222 can be configured as a block structure with a certain degree of elasticity, thereby allowing it to be at least partially embedded in the first transition hole 221a to achieve a sealing effect on the first transition hole 221a. Furthermore, to facilitate the installation of the first sealing cap 222 and the cap support 221, a cap connecting portion 222a can be provided at one end of the first sealing cap 222, which is embedded and positioned with the cap support 221. The cap connecting portion 222a includes a first plate-shaped connecting portion and a fitting pin provided on the lower side of the first plate-shaped connecting portion. To facilitate the connection of the fitting pin, an installation through hole can be provided on the cap support 221. The first sealing cap 222 can then be conveniently installed on the cap support 221 through the fitting connection between the fitting pin and the installation through hole. Furthermore, to prevent the fitting from coming out, an annular protrusion with a certain degree of elasticity can be provided on the fitting. This allows the fitting to reliably restrict movement after it has been inserted and installed, thanks to the elastic recovery of the annular protrusion.

[0069] Furthermore, to facilitate the connection between the cover connecting portion 222a and the first sealing cover 222, a bendable elastic connecting structure (such as an elastic connecting plate) can be provided between the first plate-shaped connecting portion and the first sealing cover 222. This allows the first sealing cover 222 to be folded upwards to a position opposite to the cover connecting portion 222a. Furthermore, a clamping protrusion can be provided at the other end of the first sealing cover 222 to facilitate opening the first sealing cover 222. This clamping protrusion is positioned on the upper side of the end of the first sealing cover 222, creating a certain misalignment between the clamping protrusion and the first sealing cover 222, thus facilitating clamping and folding of the entire first sealing cover 222. Moreover, the clamping protrusion, once folded into place, can be engaged with a pre-reserved notch on the generator housing 1 to fix the first sealing cover 222, thereby improving the ease of use of this invention.

[0070] Combination Figure 6 and Figure 7 As shown, according to one embodiment of the present invention, at least one second dividing member 1b1 is provided with a baffle blade 1b11 on its lower side; wherein, the number of baffle blades 1b11 can be determined based on the length of the first transition hole 221a. In this embodiment, the baffle blade 1b11 is a curved blade, and the bending direction of the cross-section of the baffle blade 1b11 is consistent with the bending direction of the second dividing member 1b1; furthermore, the lower end of the baffle blade 1b11 is spaced apart from the second partition plate 215.

[0071] Through the above configuration, the present invention, by setting baffle blades 1b11 in the atomizing chamber 212, forms a guiding effect for the generated water negative ion mist in the atomizing chamber 212, so that most of the water mist can be output from most of the openings of the first transition hole 221a corresponding to the baffle blades 1b11 and the first partition 214. Furthermore, by setting the baffle blades 1b11 as curved blades, the water mist can be deflected during the process of being blocked and turned by the baffle blades 1b11, based on the curved surface of the baffle blades 1b11, so that the deflection effect of the water negative ion mist during the output process is further enhanced, thereby making it easier for the water negative ion mist to be transported to a farther position after output to achieve matching and mixing with the air curtain formed by the first opening 1a, which greatly improves the transmission and distribution effect of water negative ions of the present invention.

[0072] Furthermore, the baffle blade 1b11 allows some of the negative water ion mist to be delivered through a small-area channel formed between the baffle blade 1b11 and the surrounding wall to the space between the baffle blade 1b11 and the wall of the atomizing chamber 212. This causes the negative water ion mist to be output from a small opening of the first transition hole 221a corresponding to the space between the baffle blade 1b11 and the wall of the atomizing chamber 212. This results in a relative difference in the output of the negative water ion mist, which is more beneficial to the overall expansion and distribution of the mist output through the second opening 1b. In particular, near the first opening 1a, this differentiated output of negative water ion mist can be more easily drawn into the natural wind output by the first opening 1a, which is more beneficial to improving the distribution effect of the present invention.

[0073] Furthermore, the baffle blade 1b11 is positioned opposite the transition portion of the second baffle 215. Thus, when the water mist containing negative ions passes through the channel between the baffle blade 1b11 and the second baffle 215, the water mist can be further redirected by the bending action of the transition portion, which is more beneficial for the output of water mist containing negative ions in a confined space.

[0074] Furthermore, the partitioned output of water negative ion mist is achieved through the set baffle blades 1b11, which effectively suppresses the water mist congestion caused by the perpendicularity between the water negative ion mist generation direction and the output direction in the excessively large atomizing chamber 212. This effectively reduces the residence time of water negative ion mist in the atomizing chamber 212 and eliminates some of the preconditions that lead to the condensation of water negative ion mist.

[0075] like Figure 8 As shown, according to one embodiment of the present invention, the distance between the baffle blade 1b11 and the front side plate of the atomizing chamber 212 is less than the distance between the baffle blade 1b11 and the first baffle 214.

[0076] With the above configuration, the atomizing chamber 212 can be divided into two spaces of different sizes by the baffle blade 1b11 in the extension direction of the free end. As a result, the output speed and output amount of the water negative ion mist formed in the atomizing chamber 212 are unevenly distributed. This is more conducive to achieving a difference in the output distance of the water negative ion mist in the output direction of the second opening 1b, and thus makes it easier for the water negative ion mist to be mixed with the natural wind output from the first opening 1a to achieve a better uniform distribution effect.

[0077] Combination Figure 6 , Figure 7 and Figure 8 As shown, according to one embodiment of the present invention, the thickness of the partition blade 1b11 is configured to gradually decrease from the connecting end toward the second partition 215.

[0078] By setting the thickness of the baffle blade 1b11 to be variable, the strength of the baffle blade 1b11 decreases as the thickness decreases. Therefore, the baffle blade 1b11 can achieve a micro-vibration effect when subjected to external vibration or impact. Consequently, under the impact of the water mist sprayed by the vibrating friction plate 23 and / or the vibration during wear, at least a portion of the baffle blade 1b11 can generate a certain degree of micro-vibration, thereby disturbing the water mist in the atomizing chamber 212. This more effectively suppresses water mist retention in the atomizing chamber 212 and is more beneficial for accelerating the discharge of water mist. Simultaneously, the vibration disturbance effect of the baffle blade 1b11 can effectively avoid the drawback of water mist retention leading to condensation. Furthermore, the baffle blade 1b11, through the above-mentioned configuration, can also effectively collect a small amount of condensed water downwards based on its vibration effect, allowing the condensed water to be promptly recovered to the return water chamber 213.

[0079] like Figure 8As shown, according to one embodiment of the present invention, the extending direction of the baffle blade 1b11 can be set to be perpendicular to the first plate-shaped portion of the second baffle 215. This allows the baffle blade 1b11 to be directly opposite the generated water mist containing negative ions, thus making the matching vibration of the baffle blade 1b11 during the water mist generation process more beneficial. In another embodiment, the baffle blade 1b11 can also be set to be inclined relative to the first plate-shaped portion of the second baffle 215. For example, along the extending direction of the baffle blade 1b11, the gap between the baffle blade 1b11 and the first baffle 214 gradually decreases. Furthermore, the inclined baffle blade 1b11 can guide the blocked water mist towards the outlet direction based on its inclined state. Therefore, by controlling the inclination angle of the baffle blade 1b11, an optimized match between the water mist extraction efficiency and the vibration turbulence of the baffle blade 1b11 can be achieved, which is more beneficial for improving the efficient extraction of water mist containing negative ions.

[0080] Combination Figure 6 and Figure 7 As shown, according to one embodiment of the present invention, the partition blade 1b11 can be made of the same material as the cover support 221, or it can be made of an elastic material (such as a silicone sheet). Of course, the partition blade 1b11 can be made of a combination of multiple materials as needed. For example, the upper end of the partition blade 1b11 connected to the cover support 221 can be made of the same material, while the lower end of the partition blade 1b11 can be made of an elastic material to achieve more beneficial working performance.

[0081] According to one embodiment of the present invention, a hydrophobic layer may be further provided on the outer surface of the baffle blade 1b11. The hydrophobic layer further suppresses the adhesion and condensation of negative water ions on the surface, thus benefiting the rapid and reliable output of negative water ions. Alternatively, the hydrophobic layer can also be provided on the wall of the atomizing chamber 212, the side of the second dividing member 1b1, or other locations in contact with the output of negative water ions to further optimize the output path of negative water ions and suppress condensation.

[0082] like Figure 5 As shown, according to one embodiment of the present invention, the water inlet 211a of the water storage cavity 211 is located on the upper side of the water storage cavity 211, that is, the water inlet 211a is located on the upper side of the annular enclosure of the water tank body 21a, thereby allowing water to be injected into the water storage cavity 211 from above. Furthermore, to facilitate the sealing of the water inlet 211a, a water inlet cap 222b can be further provided on the first sealing cap 222, see [reference]. Figure 6The water inlet cap 222b can be fitted into the water inlet 211a to achieve a sealing effect. Furthermore, the water inlet cap 222b is connected to the first sealing cap 222 via an elastic connector (such as an elastic connecting plate) to facilitate opening and folding. In this embodiment, to facilitate removal of the water inlet cap 222b, a groove can be provided on the side of the water inlet cap 222b to allow it to be easily removed from the water inlet 211a.

[0083] According to one embodiment of the present invention, the cover support 221 can be installed on the upper side of the annular enclosure of the water tank body 21a using a threaded connector. To ensure the airtightness of the connection point, an annular sealing ring is further provided at the installation location to improve the airtightness of this solution and prevent the leakage of water negative ion mist. Furthermore, connecting the cover support 221 to the generator housing 1 via the threaded connector achieves the installation and fixation of the water negative ion generating unit 2, and the sealing ring further provided between the installation locations ensures the airtightness of the connection location, preventing the penetration of water negative ions into the generator housing 1.

In this embodiment, the air outlet 321a is connected to the first opening 1a; the fan connection interface 322a is connected to the fan outlet of the centrifugal fan 31.

[0085] In this embodiment, when a water negative ion generating unit 2 is simultaneously installed on the free end of the fan unit 3, the air guide structure 32 is fixedly connected to the cover support 221 of the generating unit cover 22. (See also...) Figure 6 When the water negative ion generating unit 2 is not installed on the free end of the fan unit 3, the air guide structure 32 is installed separately, see [reference].

[0087] The negative ion generator 6 can further generate negative air ions in the air outlet cavity 321 to supplement the water mist of negative water ions output by the water negative ion generating unit 2, thus more effectively supplementing the use effect of the present invention.
