Description

Technical Field

[0001] The present invention relates to the field of portable air treatment devices, and particularly to a neck-mounted water negative ion generator. Background Art

[0002] In today's society, with the acceleration of the industrialization process and the continuous expansion of the urbanization scale, the air pollution problem has become increasingly severe, and the impact of air quality on human health has also become more significant. This situation has drawn the public's high attention to air quality. Negative ions, due to their many beneficial characteristics for human health such as purifying air, improving breathing quality, and enhancing immunity, have been widely recognized. Against this background, air treatment devices have gradually become popular products in the market. In particular, portable air treatment devices, because they can meet people's needs for fresh air in different scenarios, are favored by more and more consumers.

[0003] In order to further improve portability and ease of use, neck-mounted air treatment devices have emerged. Such devices generally adopt a lightweight design concept, and users can easily wear them around the neck. The device can continuously provide treated air, effectively improving the air quality of the surrounding small environment and bringing a relatively fresh air experience to people in various scenarios such as traveling and working.

[0004] However, the current neck-mounted air treatment devices on the market have many deficiencies. On the one hand, although negative ions are of great significance for air purification and human health, most of the existing neck-mounted air treatment devices cannot generate stable water negative ions. Compared with ordinary negative ions, water negative ions have unique advantages in air purification, moisture retention, etc., and can bring a better air improvement experience to users. Therefore, it has become an urgent task to develop a neck-mounted air treatment device that can generate stable water negative ions.

[0005] On the other hand, the existing neck-mounted air treatment devices have defects in structural and functional designs. Taking the Chinese utility model patent "CN214791731U - Wearable Air Treatment Device" as an example, such devices usually rely on air flow and water mist to work to adjust air humidity. The water mist generated by the humidification module will pass through the wind wheel, and the negative ion generator is also set on the moving path of the water mist. Such a design causes the water mist to inevitably erode the relevant electrical and mechanical parts during the operation of the device. In the long run, the performance of the entire device will be severely affected, and the durability of the device will also be greatly reduced. This not only increases the usage cost of consumers but also affects the user experience and limits the further development of neck-mounted air treatment devices. Summary of the Invention

[0011] According to one aspect of the present invention, the generating unit cover comprises: 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 water negative ion outlet respectively; The first transition hole is provided with a plurality of second split pieces arranged at intervals in the extension direction of the free end; The second splitting piece is a curved structural piece; The outer end of the second dividing piece is bent in a direction away from the free end.

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

[0013] According to one aspect of the present invention, the spacing distance between the barrier blade and the front side plate of the atomization chamber is smaller than the spacing distance between the barrier blade and the first barrier plate.

[0014] According to one aspect of the present invention, the thickness of the barrier blade is gradually reduced from the connecting end toward the second partition plate.

[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 guide 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; An air outlet is provided on the upper side of the air outlet cavity, and a fan docking port is provided on the lower side of the air inlet cavity; The air outlet is connected to the first opening; The blower interface is docked with the blower air outlet of the centrifugal blower.

[0016] According to one aspect of the present 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 solution of the present invention, by separately arranging the water negative ion generating unit and the fan unit at the outlet, the physical isolation of the mist outlet path of the water negative ion generating unit and the air outlet path of the fan unit can be achieved, thereby effectively avoiding the influence and erosion of the water negative ion water mist on the circuit part structure, and effectively ensuring the use reliability and service life of the present invention.

[0018] According to one solution of the present invention, by separately arranging the water negative ion generating unit and the fan unit at the outlet, the layout of the outlet can be made more flexible. Among them, only by separately arranging the mist outlet path of the water negative ion generating unit and the air outlet path of the fan unit, the flexible arrangement of the outlet position can be realized, greatly improving the diversity of the design combination of this solution, and effectively improving the use performance of the present invention. In addition, through the independently designed mist outlet path of the water negative ion generating unit, the outlet can be further led out to different positions of the generator housing, such as on two opposite free ends, greatly improving the expandability of the design of the water negative ion outlet position of the present invention.

[0019] According to one solution of the present invention, based on the arranged first partition member and its bending manner away from the free end, the air flow direction of the output natural wind can be effectively guided, so that the natural wind flows to the corresponding target area according to the design intention when passing through the air outlet, thereby more conveniently realizing the uniform distribution of the generated water negative ion water mist in the target area. Further, by setting the bending degree of the first partition member, the deflection guidance of the air flow direction can be further realized, thereby effectively avoiding the impact of the air outlet on the target area, making the formed air curtain softer, which is more beneficial to improving the use effect of the present invention. Moreover, the deflected and guided air flow can realize the inward convergence of the carried water negative ion water mist, so as to achieve a longer residence effect during the uniform distribution of the water negative ion water mist.

[0020] According to one solution of the present invention, based on the set second dividing member and the way it bends in the direction away from the free end, it can effectively guide the flow direction of the water negative ion mist, so that the water negative ion mist can flow to the air curtain area output from the first opening according to the design intention when passing through the first transition hole, so that the water negative ions are dispersed by the natural wind; further, based on the set second dividing member, by flexibly setting its bending degree, the deflection guidance of the mist flow direction can be further realized, and then the water negative ions can be more conveniently and accurately introduced into the air curtain area output from the first opening, which is more beneficial to improving the use effect of the present invention. According to one solution of the present invention, the present invention forms a guiding effect on the generated water negative ion mist in the atomization chamber by setting partition blades in the atomization chamber, so that most of the mist can be output from most of the openings of the first transition hole corresponding to the partition blades and the first partition; further, by setting the partition blades as curved blades, the deflection of the mist flow process can be realized based on the curved surface of the partition blades when the mist is blocked by the partition blades and turns, so that the deflection effect of the water negative ion mist during the output process is further enhanced, so that the water negative ion mist is more easily transported to a farther position after output to match and mix with the air curtain formed by the first opening, greatly improving the transmission and distribution effect of the water negative ions of the present invention.

[0021] According to one solution of the present invention, the set partition blades can send part of the water negative ion mist to the space between the partition blades and the wall surface of the atomization chamber through the small-area channel formed between the partition blades and the surrounding wall surface, so that the water negative ion mist is output from a small part of the openings of the first transition hole corresponding to the partition blades and the wall surface of the atomization chamber. Thus, the output of the water negative ion mist shows a relative difference, which is more beneficial to the overall expansion distribution of the mist output through the second opening. Especially, at the position close to the first opening, the water negative ion mist with this differential output can be more easily involved in the natural wind output from the first opening, which is more beneficial to improving the distribution effect of the present invention.

Specific embodiments

[0023] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for the embodiments. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0024] When describing the embodiments of the present invention, the orientation or positional relationships expressed by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" are based on the orientation or positional relationships shown in the relevant drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.

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

[0026] Combined with Figure 1 、 Figure 2 and Figure 3As shown, according to an embodiment of the present invention, a neck-hanging water negative ion generator of the present invention includes: a generator housing 1 convenient for neck hanging, a water negative ion generation unit 2, a fan unit 3, a power supply unit 4, and a control unit 5 disposed in the generator housing 1; in this embodiment, the outer shape of the generator housing 1 determines the outer shape of the entire neck-hanging water negative ion generator, and it is the main support structure of the entire neck-hanging water negative ion generator; wherein, the generator housing 1 is a hollow structure for installing and arranging the water negative ion generation 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 generation 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 generation unit 2, and the fan unit 3 respectively; the power supply unit 4 provides working power for the control unit 5, the water negative ion generation unit 2, and the fan unit 3 respectively, and the control unit 5 controls the operation of the water negative ion generation unit 2 and the fan unit 3 respectively.

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

[0028] In this embodiment, at least one water negative ion generation unit 2 is provided for generating water negative ion water mist; wherein, referring to Figure 1 , taking the water negative ion generation unit 2 being set as one as an example, it can be arranged adjacent to one of the fan units 3, and the water negative ion generation unit 2 and the fan unit 3 are arranged in parallel along the extension direction of the free end; through the adjacent arrangement of the water negative ion generation unit 2 and the fan unit 3, it is convenient to mix the water negative ion water mist generated by the water negative ion generation unit 2 with the wind curtain generated by the nearby fan unit 3, and then under the driving action of the wind curtain, it is carried to the target area. Correspondingly, since the opposite fan unit 3 also has a generated wind curtain, the blown water negative ion water mist is blocked, and under the interaction of the opposite wind curtains, the water negative ion water mist can reciprocate between the two to achieve uniform distribution and residence between the two wind curtains. In addition, due to the action effect of the opposite wind curtains, the sedimentation speed of the water negative ion water mist under the action of gravity can be effectively inhibited, so as to achieve the effect of long-term residence.

[0029] In this embodiment, a first opening 1a for the water negative ion generating unit 2 to output water negative ions and a second opening 1b for the fan unit 3 to discharge air 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 extending direction of the free end, wherein the first opening 1a starts from the end of the free end and extends in a direction away from the end face of the free end, and correspondingly, the second opening 1b starts from a position adjacent to the first opening 1a and extends in a direction 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, and the extending lengths of the first opening 1a and the second opening 1b can be set respectively according to the actual situation, so as to realize the matching control of the output water negative ion water mist and the output air volume at the two opening positions, so as to facilitate the realization of the mixing effect at the two opening positions. Further, in order to realize the distribution range of the natural wind output at the position of the first opening 1a, the first opening 1a can start from the end face or the corner position of the end face of the free end, so as to realize the output of the air volume at the corner position of the free end, and fully improve the covering 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. Among them, along the direction from the inner side to the outer side of the width direction of the free end, the second opening 1b and the first opening 1a are arranged in sequence. Thus, the natural wind output from the first opening 1a can surround the water negative ion water mist output from the second opening 1b, so as to more conveniently realize the dispersion of the water negative ion water mist, and thus be conveniently conveyed between the air curtains formed by the opposite two, making the distribution of the water negative ions more sufficient.

[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 extending 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; thus, the mixing between each other can be realized at the positions of air outlet and water mist outlet, so that the uniform distribution can be realized more fully and conveniently.

[0032] In another embodiment, the first opening 1a and the second opening 1b can be combined in two or three ways of being arranged side by side along the extending direction of the free end, arranged side by side along the width direction of the free end, and at least partially overlapped. Among them, the first opening 1a and the second opening 1b can be respectively set as multiple parts, and each part adopts different setting methods to achieve the combination of multiple setting methods, so as to flexibly realize different mixing effects of the output natural wind and water negative ion water mist, so as to make the use effect of the present invention better; in this embodiment, for the convenience of the corresponding layout, the internal conveying pipeline can be flexibly set to adapt to the corresponding layout flexibility.

[0033] With the above settings, by separately arranging the water negative ion generating unit 2 and the fan unit 3 at the outlets, the physical isolation of the mist outlet path of the water negative ion generating unit 2 and the air outlet path of the fan unit 3 can be achieved, thereby effectively avoiding the influence and erosion of the water negative ion water mist on the circuit part structure, and effectively ensuring the use reliability and service life of the present invention.

[0034] In addition, by separately arranging the water negative ion generating unit 2 and the fan unit 3 at the outlets, the present invention can have higher flexibility in the layout of the outlets. Among them, only by separately arranging the mist outlet path and the air outlet path of the water negative ion generating unit 2 and the fan unit 3, the flexible arrangement of the outlet positions can be realized, greatly improving the diversity of the design combination of the present solution, and effectively improving the use performance of the present invention. In addition, through the independently designed mist outlet path of the water negative ion generating unit 2, the outlet can be further led out to different positions of the generator housing 1, such as on two opposite free ends, greatly improving the expandability of the design of the water negative ion outlet position of the present invention.

[0035] In addition, 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, further effectively increasing the flexibility of the arrangement of the water negative ion generating unit 2 and fully ensuring the use performance of the present invention.

[0036] Combined with Figure 1 and Figure 4 As shown, according to an embodiment of the present invention, the generator housing 1 is integrally of a symmetrical structure, which includes: an intermediate connecting portion 11, a first support arm 12 and a second support arm 13; wherein, the hollow connecting portion 11 is a hollow curved tubular structure, and both of its opposite ends are open ends, so that the first support arm 12 and the second support arm 13 can be respectively installed at the opposite ends of the intermediate connecting portion 11; in this embodiment, the first support arm 12 and the second support arm 13 are detachably installed with the intermediate connecting portion 11. Further, for the convenience of using the generator housing 1, the intermediate connecting portion 11 can be set to be an elastic structure. Thus, when wearing, by applying forces to the first support arm 12 and the second support arm 13 in opposite directions, the opening width can be increased to facilitate the wearing operation, and after the first support arm 12 and the second support arm 13 are released after wearing, the elastic recovery of the intermediate connecting portion 11 can be realized, so that the generator housing 1 is reliably worn on the neck.

[0037] In this embodiment, both the first support arm 12 and the second support arm 13 are hollow tubular structures. Among them, both the first support arm 12 and the second support arm 13 are provided with open ends to achieve sleeving and locking with the ends of the intermediate connecting portion 11, while the other ends of the first support arm 12 and the second support arm 13 form corresponding free ends.

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

[0039] In this embodiment, a plurality of contact protrusions can be regularly arranged on the side surface of the tubular main body 111. Among them, there are intervals between adjacent contact protrusions. When the neck-mounted water negative ion generator of the present invention is worn, dispersed contact is formed between the contact protrusions and the skin, avoiding the entire surface contact between the tubular main body 111 and the skin, thereby improving the air permeability and wearing comfort of the wearing position. In addition, the water negative ion generating unit 2, the fan unit 3, the power supply unit 4, and the control unit 5 are distributed in the first support arm 12 and the second support arm 13, making the mass distribution of the neck-mounted water negative ion generator of the present invention more reasonable, which is conducive to achieving stable contact between the contact protrusions and the skin during wearing; furthermore, based on the slight vibrations during the operation of the water negative ion generating unit 2 and the fan unit 3, as well as the vibrations generated by the user's movement, the contact protrusions can generate varying contact stresses at the contact positions, reducing wearing fatigue and enhancing the user experience.

[0040] In this embodiment, the structures of the first connecting member 112 and the second connecting member 113 are the same, and the first connecting member 112 and the second connecting member 113 are rigid structural members, and the hardness of their materials is greater than the hardness of the tubular body 111 to fully ensure the reliable stability of the connection position. For this purpose, it includes: a connecting member main body a1 and a connecting member rib a2; wherein, the connecting member main body a1 is a ring structure, and an annular protrusion is provided at its end, and then an annular groove matching the annular protrusion is provided inside the end of the tubular body 111 to facilitate the fitting connection between the connecting member main body a1 and the tubular body 111, and to ensure the stable and reliable connection, glue can be further provided at the fitting position to achieve the cementation between each other. Further, the connecting member rib a2 is arranged inside the connecting member main body a1, it is arranged in the middle position of the connecting member main body a1 in the vertical direction, and both sides in the width direction of the connecting member rib a2 are fixedly connected to the opposite sides in the horizontal direction of the connecting member main body a1 respectively to ensure the stable and reliable structure of the outer shape of the connecting member main body a1.

[0041] In this embodiment, positioning and mounting holes can also be provided on the connecting member main body a1, and the axial direction of the positioning and mounting holes is arranged in the horizontal direction. Thus, the connecting member main body a1 can be positioned and mounted with the open end of the first support arm 12 or the second support arm 13 by arranging positioning posts inside the open ends of the first support arm 12 and the second support arm 13 to pass through the positioning and mounting holes. Further, the first support arm 12 or the second support arm 13 can be locked with the connecting member main body a1 by using the locking function of the threaded connecting member to ensure the convenience and reliability of the connection.

[0042] Further, along the horizontal direction, fitting and positioning grooves can be provided on the side surface of the connecting member main body a1, and the fitting and positioning grooves correspond to the positions of the positioning and mounting holes of the connecting member main body a1. Thus, fitting and positioning protrusions matching the fitting and positioning grooves can be further provided inside the open ends of the first support arm 12 and the second support arm 13, and the fitting and positioning protrusions correspond to the positions of the provided positioning posts. Furthermore, when the positioning and mounting holes are inserted in cooperation with the positioning posts inside the open ends of the first support arm 12 or the second support arm 13, the cooperation of the corresponding fitting and positioning grooves and the fitting and positioning protrusions can be realized to further achieve reliable and stable installation.

[0043] Such as Figure 4As shown, according to an embodiment of the present invention, the first support arm 12 includes: a first support arm main body 121 and a first support arm cover body 122; wherein, the first support arm main body 121 and the first support arm cover body 122 are provided with a snap-fit structure that engages with each other at the edge position (i.e., a snap-fit structure in which a snap and a slot cooperate); further, a positioning post for matching the positioning installation hole on the connecting member main body a1 can be provided inside the first support arm main body 121, and a threaded connection post is provided inside the first support arm cover body 122, and the threaded connection post and the positioning post can be fitted and installed in a nested manner; further, for the convenience of installing the threaded connecting member and the threaded connection post, the positioning post can be correspondingly set to be hollow, and an opening is formed on the side surface of the first support arm main body 121 to facilitate the threaded connecting member to pass through the positioning post to achieve locking with the threaded connection post, thereby realizing the structural stability of the first support arm 12. In addition, to further ensure the surface continuity and smoothness of the position where the threaded connecting member is provided, a first fastening member 123 can be further provided.

[0044] In this embodiment, a first filter element installation cavity 1211 that protrudes inward is provided below the first opening 1a of the first support arm main body 121. Thus, it is convenient to respectively arrange a filter element and a fan unit 3 on opposite sides of the first filter element installation cavity 1211; further, to close the first filter element installation cavity 1211, a first filter cavity cover body 124 can be further provided to facilitate the replacement of the filter element installed therein. In this embodiment, the first filter cavity cover body 124 is provided with a hollowed-out pattern to form a channel for air to enter.

[0045] In this embodiment, to facilitate the fan unit 3 to suck in sufficient air, openings are correspondingly provided at positions on the wall surface of the first filter element installation cavity 1211 corresponding to the fan unit 3, so that air can be sucked in by the fan unit 3 through the filter element and discharged from the first opening 1a.

[0046] As Figure 4As shown, according to an embodiment of the present invention, the second support arm 13 includes: a second support arm main body 131 and a second support arm cover 132; wherein, the second support arm main 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 snap and a slot cooperate) at the edge position; further, a positioning post for matching with the positioning installation hole on the connector main body a1 can be arranged on the inner side of the second support arm main body 131, and a threaded connection post is arranged on the inner side of the second support arm cover 132, and the threaded connection post and the positioning post can be fitted and installed in a nested manner; further, in order to facilitate the installation of the threaded connector and the threaded connection post, the positioning post can be correspondingly set to be hollow, and an opening is formed on the side surface of the second support arm main body 131 to facilitate the threaded connector to pass through the positioning post to lock with the threaded connection post, thereby realizing the structural stability of the second support arm 13. In addition, in order to further ensure the continuous and smooth surface of the position where the threaded connector is set, a second snap-fit member 133 can be further provided.

[0047] In this embodiment, a second filter element installation cavity 1311 protruding inward is provided below the first opening 1a of the second support arm main body 131.

[0048] In this embodiment, in order to facilitate the fan unit 3 to suck in enough air, openings are correspondingly arranged at positions on the wall surface of the second filter element installation cavity 1311 corresponding to the fan unit 3, so that air can be sucked in by the fan unit 3 through the filter element and discharged from the first opening 1a.

[0049] According to an embodiment of the present invention, the two free ends of the generator housing 1 extend in a direction approaching each other in the horizontal direction. Refer to Figure 1 ; Thus, in the free state of the generator housing 1, the opening of the generator housing 1 can be effectively reduced to ensure reliable wearing. In this embodiment, the two free ends are extended close to each other in an arc-shaped bending manner; thus, the extending directions of the first opening 1a and the second opening 1b arranged on the generator housing 1 can match the extending directions of the free ends, and thus, the blown air curtain and the water negative ion water mist are more likely to adapt to the facial contour of the user, realizing the accurate distribution of the air curtain and the water negative ions around the face.

[0050] Further, the two free ends of the generator housing 1 extend in a downwardly inclined direction in the vertical direction. Refer toFigure 3 . By extending the free end in a downward tilted direction, the first opening 1a and the second opening 1b provided thereon can be further oriented in an upward oblique direction, thereby fully achieving the distribution of the blown water negative ion mist and natural wind in the target area in front of the human mouth and nose, so as to fully ensure the accuracy of their distribution in the target area. In this embodiment, the free end starts to extend downward from the position where the generator housing 1 contacts the user's shoulder, thereby fully achieving the first opening 1a and the second opening 1b just below the user's face, thereby, the water negative ion mist and natural wind sprayed obliquely upward based on the first opening 1a and the second opening 1b are more accurately distributed in front of the user's face. Furthermore, by bringing the first opening 1a closer to the end of the free end, the wind curtain continuously output based on the first opening 1a is below the water negative ion mist output based on the second opening 1b, thereby fully achieving the effect of receiving the water negative ion mist, thereby achieving the effect of sufficient mixing and long-term residence of the water negative ion mist.

[0051] like Figure 4 As shown, according to one embodiment of the present invention, the first opening 1a is provided with a plurality of first split pieces 1a1 arranged at intervals in the extension direction of the free end; wherein the first split piece 1a1 is a curved structural member; for example, the first split piece 1a1 can be configured as a curved plate-like structural member or a curved strip-like structural member. Furthermore, in the first opening 1a, the first split piece 1a1 is bent in a direction away from the free end, and the outer end of the first split piece 1a1 is bent in a direction away from the free end; specifically, along the width direction of the free end, the distance between one end of the first split piece 1a1 facing the inner side 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 split piece 1a1 and the end face of the free end.

[0052] Through the above-mentioned setting, based on the setting of the first dividing piece 1a1 and the way in which it bends in the direction away from the free end, the airflow direction of the output natural wind can be effectively guided, so that the natural wind flows to the corresponding target area according to the design intention when passing through the air outlet, thereby more conveniently achieving the uniform distribution of the generated water negative ion mist in the target area. Furthermore, the deflection and guidance of the airflow direction can be further achieved by setting the degree of curvature of the first dividing piece 1a1, thereby effectively avoiding the impact of the wind on the target area, making the wind curtain formed by it softer, and more beneficial to improving the use effect of the present invention. Moreover, the airflow after deflection and guidance can gather the water negative ion mist obliquely upward toward the facial area, further increasing the scope of the wind curtain to receive the water negative ion mist, so as to achieve a longer-lasting residence effect in the process of uniform distribution of the water negative ion mist.

[0053] Further, by adjusting the thickness of the first dividing member 1a1, the division of the first opening 1a can be achieved. Thus, the division and blocking of the output air flow at the position of the first dividing member 1a1 can be realized, and the flexible suppression of the air flow impact can be further achieved. Moreover, the air flow passing through the first dividing member 1a1 can make the overall blowing softness better during the further confluence process.

[0054] In this embodiment, since the structure of the generator housing 1 has symmetry, the first dividing members 1a1 on the free ends arranged at the corresponding symmetric positions can exhibit a corresponding symmetric distribution manner. Thus, the air curtains formed by the relative positions can have basically the same characteristics, so as to fully realize the uniform distribution and long-term retention of the water negative ion water mist under the soft blowing effect.

[0055] Combined Figure 1 、 Figure 3 and Figure 5 As shown, according to an embodiment of the present invention, the water negative ion generating unit 2 includes: a generating unit housing 21, a generating unit cover 22, a vibration friction plate 23, and a water pump 24; wherein, the generating unit housing 21 is integrally of a hollow structure to achieve the functions of storing water and atomizing to generate water negative ion water mist, and its structure is compact and small in volume, which greatly facilitates the integrated installation of the water negative ion generating unit 2 of the present invention in the generator housing 1. In this embodiment, the generating unit housing 21 includes: a water storage chamber 211, an atomizing chamber 212, and a return water chamber 213; wherein, a water negative ion outlet 212a is arranged on the upper side of the atomizing chamber 212; a water injection port 211a is arranged on the water storage chamber 211; further, along the extending direction of the free end, the water storage chamber 211 is arranged at the rear side of the atomizing chamber 212; the return water chamber 213 is arranged at the lower side of the atomizing chamber 212. In this embodiment, for the convenience of separating each chamber, a first partition 214 is arranged between the water storage chamber 211 and the atomizing chamber 212, and the first partition 214 has a first water passing hole 214a; a second partition 215 is arranged between the atomizing chamber 212 and the return water chamber 213, and the second partition 215 has a first return water hole 215a.

[0056] Further, for the convenience of generating water negative ion water mist in the atomizing chamber 212, the vibration friction plate 23 is correspondingly arranged in the atomizing chamber 212, and the water inlet side of the vibration friction plate 23 is communicated with the first water passing hole 214a. In this embodiment, the vibration friction plate 23 can be realized by using existing mature friction plates, which will not be elaborated here.

[0057] Further, to facilitate the recovery of the condensed water in the atomization chamber 212, the water inlet end of the water pump 24 is correspondingly connected to the return water chamber 213, and the water outlet end of the water pump 24 is connected to the water storage chamber 211. Thus, the condensed water is recovered into the return water chamber 213 through the first return water hole 215a. Furthermore, a connecting pipe can be provided at the bottom of the return water chamber 213 to connect to the water inlet end of the water pump 24, so as to suck out the recovered water. Correspondingly, a connecting pipe is also provided between the water outlet end of the water pump 24 and the water storage chamber 211 to output the sucked-out water. In this embodiment, the water pump 24 can be set as a diaphragm water pump to fully ensure the small volume of the present invention. Moreover, based on the advantage of its small volume, the water pump 24 can be directly fixedly installed at the bottom of the water storage chamber 211 to further achieve the high integration and small volume of the water negative ion generating unit 2.

[0058] As Figure 2 shown, according to an embodiment of the present invention, the generating unit housing 21 is assembled by welding or bonding the water tank main body 21a and the water tank side cover 21b; among them, the water tank main body 21a is correspondingly arranged based on the structural design and distribution of the water storage chamber 211, the atomization chamber 212, and the return water chamber 213. Specifically, the water tank main body 21a has side plates and an annular enclosure surrounding the side plates, and the first partition plate 214 and the second partition plate 215 are correspondingly arranged and connected in the side plates and the annular enclosure, thereby dividing the corresponding water storage chamber 211, atomization chamber 212, and return water chamber 213. In this embodiment, the side plates, the annular enclosure, the first partition plate 214, and the second partition plate 215 in the water tank main body 21a are integrally formed. Further, the outer shape of the water tank side cover 21b is set to match the outer shape of the water tank main body 21a. Thus, the entire generating unit housing 21 can be formed by buckling the water tank side cover 21b with the water tank main body 21a and based on the welding or bonding method.

[0059] In this embodiment, the water negative ion outlet 212a is arranged on the upper side of the annular enclosure of the water tank main body 21a to communicate with the atomization chamber 212, and the second partition plate 215 is arranged below opposite to the water negative ion outlet 212a. Among them, the second partition plate 215 includes a first plate-like part, a transition part, and a second plate-like part; in the direction from the first partition plate 214 to the front side wall of the atomization chamber 212, the first plate-like part, the transition part, and the second plate-like part are connected in sequence. Among them, the first plate-like part is arranged parallel to the lower side wall of the return water chamber 213, and the transition part is an arc-shaped plate, and the transition part is bent in the direction towards the upper side of the atomization chamber 212. Correspondingly, the second plate-like part is respectively connected to the end of the transition part and the front side wall of the atomization chamber 212, so that the second plate-like part presents an upwardly tilted state.

[0060] In this embodiment, a linear groove or a linear hole for embedding the lower end of the vibration friction plate 23 is provided on the first plate-shaped portion. Thus, the limit installation of the lower end of the vibration friction plate 23 can be realized. Correspondingly, the upper end of the vibration friction plate 23 is connected to the first partition plate 214 based on a threaded connector, so that the water inlet end of the vibration friction plate 23 can accurately and tightly dock with the first water passing hole 214a. In this embodiment, a sealing structure such as a sealing gasket can be further provided around the water inlet end of the vibration friction plate 23 and the first water passing hole 214a to fully ensure that the water in the water storage cavity 211 is reliably input into the vibration friction plate 23 and effectively avoid water leakage.

[0061] In this embodiment, the first return water hole 215a can be set as a linear hole, which can start from the first plate-shaped portion and terminate at the end of the second plate-shaped portion. Thus, the first return water hole 215a can have a sufficient length to fully recover the condensed water. In this embodiment, to reduce the processing difficulty of the first return water hole 215a, the first return water hole 215a can be set at the position where the second partition plate 215 is connected to the water tank side cover 21b. Specifically, a groove with a shape matching the first return water hole 215a can be processed on the side edge of the second partition plate 215, and after the water tank main body 21a and the water tank side cover 21b are fixedly connected, the formation of the first return water hole 215a can be realized.

[0062] Through the above settings, the present invention effectively increases its opening area by setting the long strip-shaped first return water hole 215a, enabling it to fully recover the condensed water in a large range area. In addition, by setting the second partition plate 215 as a partially bent structure, thus, based on the overall structure of the generator housing 1 and the downward inclination state during wearing, the condensed water can flow more easily along the first return water hole 215a and flow back to the lower return water cavity 213, making the return water of the present invention easier.

[0063] In this embodiment, to facilitate timely viewing of the water level in the water storage cavity 211, a transparent window can be provided on the water tank main body 21a. Correspondingly, for the convenience of the user to view in a timely manner, an opening can be further provided on the generator housing 1 corresponding thereto.

[0064] Combined Figure 1 、 Figure 2 and Figure 6As shown, according to an embodiment of the present invention, the generating unit cover 22 includes: a cover support 221 and a first closing cover 222; wherein, the cover support 221 is provided with a first transition hole 221a; the first transition hole 221a is respectively communicated with the second opening 1b and the water negative ion outlet 212a; 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 member 1b1 is a curved structural member; for example, the second dividing member 1b1 can be arranged as a curved plate-shaped structural member or a curved strip-shaped structural member. Further, in the first transition hole 221a, the second dividing member 1b1 bends along the direction away from the free end, and the outer end of the second dividing member 1b1 bends in the 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 less than the distance between the other end of the second dividing member 1b1 and the end face of the free end.

[0065] Through the above settings, based on the arranged second dividing member 1b1 and its bending manner along the direction away from the free end, the flow direction of the water mist of the output water negative ions can be effectively guided, so that the water mist of the water negative ions can flow to the air curtain area output from the first opening 1a according to the design intention when passing through the first transition hole 221a, thereby enabling the water negative ions to be dispersed by the natural wind; further, based on the arranged second dividing member 1b1, by flexibly setting its bending degree, the deflection guidance of the water mist flow direction can be further realized, so that the water negative ion water mist is distributed obliquely upward towards the facial area, and then can be more conveniently and accurately introduced into the air curtain area output from the first opening 1a when descending under the action of gravity, which is more beneficial to improving the use effect of the present invention.

[0066] Further, by adjusting the thickness of the second dividing member 1b1, the division of the first transition hole 221a can be realized. Thus, the division and blocking of the output water mist at the position of the second dividing member 1b1 can be realized, and the flexible suppression of the water mist flow velocity can be further realized, and the water mist passing through the second dividing member 1b1 can present a more extensive dispersion effect during the further confluence process.

[0067] Combined Figure 6 and Figure 7 As shown, according to an 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 has a spaced arrangement from the upper side of the cover support 221. Thus, a groove-shaped structure can be formed between the upper end of the second dividing member 1b1 and the upper side of the cover support 221, which is convenient for the embedding of the first closing cover 222.

[0068] See Figure 6As shown, in this embodiment, the first closing cover 222 can be configured as a block-shaped structure with a certain elasticity, so that it can 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 closing cover 222 and the cover support 221, a cover connecting portion 222a can be provided at one end of the first closing cover 222 to be embedded and positioned with the cover support 221, wherein the cover connecting portion 222a includes a first plate-shaped connecting portion and an embedding nail provided on the lower side of the first plate-shaped connecting portion. To cooperate with the connection of the embedding nail, a mounting through hole can be provided on the cover support 221, and then the first closing cover 222 can be conveniently installed on the cover support 221 through the embedding connection between the embedding nail and the mounting through hole. Furthermore, in order to prevent the embedded nail from falling out, an annular protrusion with a certain elasticity can be provided on the embedded nail. Thus, after the embedded nail is embedded and installed, the elastic recovery of the annular protrusion can play a reliable limiting role to prevent the embedded nail from falling out.

[0069] Furthermore, to facilitate the connection between the cover body connecting portion 222a and the first closing 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 closing cover 222, thereby allowing the first closing cover 222 to be folded upward to a position opposite to the cover body connecting portion 222a; further, a clamping protrusion can be provided at the other end of the first closing cover 222 to facilitate opening the first closing cover 222, and the clamping protrusion is provided on the upper side of the end portion of the first closing cover 222 so that the clamping protrusion and the first closing cover 222 have a certain misalignment, thereby facilitating the clamping protrusion to be clamped to drive the entire first closing cover 222 to be folded; moreover, through the provided clamping protrusion, after the first closing cover 222 is folded into place, the first closing cover 222 can be fixed after being folded by engaging the clamping protrusion with the notch reserved on the generator housing 1, thereby improving the convenience of use of the present invention.

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

[0071] Through the above settings, in the present invention, by arranging the partition blade 1b11 in the atomization chamber 212, a guiding effect for the generated water negative ion water mist is formed in the atomization 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 space between the partition blade 1b11 and the first partition 214. Further, by arranging the partition blade 1b11 as a curved blade, when the water mist is blocked by the partition blade 1b11 and turns, the deflection of the water mist flow process can be realized based on the curved surface of the partition blade 1b11, so that the deflection effect of the water negative ion water mist during the output process is further enhanced, and thus the water negative ion water mist is more easily transported to a farther position after output to match and mix with the air curtain formed by the first opening 1a, greatly improving the transmission and distribution effect of the water negative ions in the present invention.

[0072] Further, through the arranged partition blade 1b11, part of the water negative ion water mist can be sent to the space between the partition blade 1b11 and the wall surface of the atomization chamber 212 through the small-area channel formed between the partition blade 1b11 and the surrounding wall surface, so that the water negative ion water mist is output from a small part of the openings of the first transition hole 221a corresponding to the space between the partition blade 1b11 and the wall surface of the atomization chamber 212. Thus, the output of the water negative ion water mist shows a relative difference, which is more beneficial to the overall extended distribution of the water mist output through the second opening 1b. Especially, at the position close to the first opening 1a, the water mist of the water negative ions with such differential output can be more easily involved in the natural wind output from the first opening 1a, which is more beneficial to improving the distribution effect of the present invention.

[0073] Further, the installation position of the partition blade 1b11 is opposite to the transition part of the second partition 215. Thus, when the water mist of the water negative ions passes through the channel position between the partition blade 1b11 and the second partition 215, the turning of the water mist of the water negative ions can be further promoted under the bending action of the transition part, which is more beneficial to the output of the water mist of the water negative ions in a narrow space.

[0074] Further, through the arranged partition blade 1b11, the partitioned output of the water negative ion water mist is realized, effectively suppressing the water mist congestion caused by the perpendicularity between the generation direction and the output direction of the water negative ion water mist in the overly large atomization chamber 212, so that the residence time of the water negative ion water mist in the atomization chamber 212 is effectively reduced, eliminating some preconditions for the condensation of the water negative ion water mist.

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

[0076] Through the above settings, the atomization chamber 212 can be separated into two spaces with different sizes by the partition blade 1b11 in the extending direction of the free end. Thus, the distribution of the output speed and output volume of the water negative ion water mist formed in the atomization chamber 212 shows an uneven effect. Therefore, it is more beneficial to achieve a difference in the output distance of the water negative ion water mist in the output direction of the second opening 1b, and then make the water negative ion water mist easier to be mixed with the natural wind output from the first opening 1a to achieve a better uniform distribution effect.

[0077] Combined with Figure 6 、 Figure 7 and Figure 8 As shown, according to an embodiment of the present invention, the thickness of the partition blade 1b11 is gradually decreased from the connecting end towards the second partition 215.

[0078] Through the above settings, the thickness of the partition blade 1b11 is set to be variable, so that the strength of the partition blade 1b11 is weakened to a certain extent with the decrease of the thickness. Thus, when the partition blade 1b11 receives external vibration or impact, it can achieve a vibration effect in a small range. Furthermore, under the impact of the water negative ion water mist ejected by the vibration friction plate 23 and / or the vibration during the wearing process, at least some areas of the partition blade 1b11 can produce a certain amount of small vibration, so as to realize the disturbance of the water mist in the atomization chamber 212, which is more beneficial to effectively inhibit the retention of the water mist in the atomization chamber 212 and promote the accelerated discharge of the water mist. At the same time, based on the vibration disturbance effect of the partition blade 1b11, the disadvantage that the water mist retention is likely to produce condensed water can be effectively avoided. Further, through the above settings of the partition blade 1b11, a small amount of condensed water can be further effectively collected downward based on its vibration effect, so that the condensed water can be recycled to the return water chamber 213 in time.

[0079] As Figure 8As shown, according to an embodiment of the present invention, the extending direction of the partition blade 1b11 can be set to be perpendicular to the first plate-like part of the second partition 215. Thus, the partition blade 1b11 can be directly opposite to the generated water negative ion water mist, and further, the matching vibration of the partition blade 1b11 during the water mist generation process can be more beneficial. In another embodiment, the partition blade 1b11 can also be set to be inclined relative to the first plate-like part of the second partition 215. For example, along the extending direction of the partition blade 1b11, the interval between the partition blade 1b11 and the first partition 214 gradually decreases. Furthermore, through the inclined partition blade 1b11, the water mist blocked can also be guided towards the outlet direction based on its inclined state. Thus, by controlling the inclination angle of the partition blade 1b11, an optimal matching between the water mist export efficiency and the vibration-induced turbulence of the partition blade 1b11 can be achieved, which is more beneficial for improving the efficient export of water negative ion water mist.

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

[0081] According to an embodiment of the present invention, a hydrophobic layer can be further provided on the outer surface of the partition blade 1b11. Through the provided hydrophobic layer, the adhesion and condensation of water negative ions on the surface can be further inhibited, which is beneficial for the rapid and reliable output of water negative ions. Of course, a hydrophobic layer can also be provided at positions in contact with the output of water negative ions, such as on the wall surface of the atomization chamber 212 and the side surface of the second partition member 1b1, etc., to further optimize the output path of water negative ions and inhibit the occurrence of its condensation.

[0082] As Figure 5 shown, according to an embodiment of the present invention, the water injection port 211a of the water storage chamber 211 is provided on the upper side of the water storage chamber 211, that is, the water injection port 211a is provided on the upper side of the annular enclosure of the water tank main body 21a. Thus, the water storage chamber 211 can be filled with water from above. Further, for the convenience of closing the water injection port 211a, a water injection port cover 222b can be further provided on the first closing cover 222. See Figure 6The water inlet cover 222b can be mounted in a matching manner with the water inlet 211a to achieve a corresponding sealing effect. Furthermore, the water inlet cover 222b is connected to the first closure cover 222 via an elastic connector (e.g., an elastic connecting plate) to facilitate opening and folding the water inlet cover 222b. In this embodiment, to facilitate removal of the water inlet cover 222b, a groove can be provided on the side of the water inlet cover 222b to facilitate removal of the water inlet cover 222b 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, wherein, in order to ensure the airtightness of the connection position, an annular sealing ring is further provided at the installation position to improve the airtightness of this solution to prevent the overflow of water negative ion mist. Furthermore, the cover support 221 can be connected to the generator housing 1 by a threaded connector to achieve the installation and fixation of the water negative ion generating unit 2, and a sealing ring can be further provided between the installation positions to achieve the sealing of the connection position to prevent the penetration of water negative ions into the generator housing 1.
