[0001] This utility model belongs to the field of air purification, specifically relating to a water negative ion mechanism and its neck-mounted water negative ion device. Background Technology

[0002] In recent years, with the escalation of air pollution, the impact of air quality on human health has received increasing attention. Consequently, air handling equipment, especially portable air purifiers, has become the choice of more and more consumers. To facilitate portability and use, neck-mounted negative air purifiers have emerged. These devices typically feature a lightweight design, can be worn around the neck, and provide a continuous supply of treated air to help improve the air quality of the surrounding environment.

[0003] Existing neck-mounted air handling devices typically rely on airflow and water mist to regulate air humidity. Taking the Chinese utility model patent "CN214791731U-Wearable Air Handling Device" as an example, the water mist generated by its humidification module passes through the impeller, and its negative ion generator is also placed in the path of the water mist. The water mist will corrode the electrical and mechanical parts of the impeller, affecting its durability. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a water negative ion mechanism and its neck-mounted water negative ion device that are highly durable, simple in structure and practical.

[0005] This utility model provides a water negative ion mechanism, including an air outlet component and a water negative ion generating component; The air outlet channel of the air outlet component is arranged adjacent to the water mist outlet of the water negative ion generating component. The flowing air from the air outlet channel drives the water mist with water negative ions generated by the water negative ion generating component at the water mist outlet to move to the target area. Furthermore, a separator is provided inside the air outlet channel, which divides the air outlet channel into two relatively independent air outlet channels I and II, with air outlet channel II located between air outlet channel I and the water mist outlet; A negative ion generator is installed in the air outlet channel I.

[0006] Furthermore, the air outlet assembly includes a fan; The air outlet channel includes an air inlet and an air outlet, and the air inlet is connected to the air outlet of the fan.

[0007] Furthermore, the air outlet channel is a rectangular channel, and the air inlet and air outlet are located on adjacent side walls of the rectangular channel.

[0008] Furthermore, the air outlet assembly also includes an air inlet channel communicating with the air inlet end, the air inlet channel being parallel to the air outlet channel, and the air outlet of the fan being connected to the inlet of the air inlet channel; The air inlet and outlet of the fan are perpendicular to each other. A filter assembly is provided on the air inlet. The air outlet channel, air inlet channel, fan and filter assembly are arranged in a rectangular pattern.

[0009] Furthermore, the water negative ion generating component includes a microporous vibrating plate and a water tank and a mist outlet chamber arranged sequentially, wherein the microporous vibrating plate is disposed on the common side wall of the water tank and the mist outlet chamber; The mist outlet is provided on the mist outlet chamber.

[0010] Furthermore, this water negative ion device also includes a housing and a seal; The outer shell, the sealing element, and the mist outlet are sequentially fitted together, and the outer shell, the sealing element, and the mist outlet are provided with interconnected water mist outlets at corresponding positions; A sealing ring is provided between the outer shell and the seal, and between the seal and the mist outlet, and the sealing ring is wrapped around the outside of the water mist outlet. Furthermore, a sealing cap is provided on the water mist outlet, and the sealing cap is made of a flexible material; One end of the sealing cap is hinged to one side of the water mist outlet on the sealing element. The sealing cap is provided with a snap-fit ​​structure I on the side away from the hinge and close to the water mist outlet. The water mist outlet position of the sealing element is provided with a snap-fit ​​engagement structure I. When the sealing cap blocks the water mist outlet, the snap-fit ​​structure I and the snap-fit ​​engagement structure I cooperate. The sealing cover is provided on the side opposite to the hinge and on the side opposite to the water mist outlet, and the outer shell is provided on the side opposite to the snap-fit ​​structure I, and the snap-fit ​​structure II engages with the water mist outlet when the sealing cover is opened.

[0011] This utility model also provides a neck-mounted water negative ion device, including the aforementioned water negative ion mechanism disposed on the neck-mounted body.

[0012] Furthermore, the air outlet and water mist outlet are arranged sequentially above the end of the neck-mounted body along the length of the neck-mounted body.

[0013] The beneficial effects of this utility model are as follows: By arranging the air outlet channel and the water mist outlet adjacent to each other, making them independent of each other, this design prevents the water mist generated by the water negative ion generator from entering the fan of the air outlet component, thus preventing moisture damage to the electrical and mechanical parts of the fan, reducing the fan's failure rate and improving its durability. This eliminates the need for excessive waterproofing and moisture-proofing of the fan's drive system, reducing the performance requirements of the fan. It also prevents water mist from accumulating inside the air outlet component, thereby reducing the risk of bacterial growth and decreasing the frequency of cleaning. Furthermore, the airflow generated by the air outlet component in the air outlet channel can move the water mist containing water negative ions to the target area. This not only moves the water mist to the target area but also enhances the diffusion effect of the water mist through airflow, effectively increasing the distribution range of water negative ions. This reduces the need for additional energy-intensive water mist delivery devices, achieving the desired effect of water negative ions while simplifying the overall structure and reducing energy consumption.

[0020] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0021] As attached Figure 1 -Appendix Figure 9 As shown, this utility model provides a water negative ion mechanism, including an air outlet component 1 and a water negative ion generating component 2, wherein the air outlet component 1 is used to circulate air, and the water negative ion generating component 2 is used to generate water mist with water negative ions. The air outlet channel 12 of the air outlet component 1 is arranged adjacent to the water mist outlet 6 of the water negative ion generating component 2. The air outlet channel 12 can be directly the air outlet 112 of the fan 11, or it can be a channel structure connected to the air outlet 112 of the fan 11. The water mist outlet 6 can be directly the water mist outlet end of the water negative ion generating component 2 with microporous vibrating plate 23, or it can be the outlet of the mist outlet chamber 22 connected to the water mist outlet end of the microporous vibrating plate 23. The air outlet channel 12 and the water mist outlet 6 are arranged adjacent to each other, so that the flowing air from the air outlet channel 12 can drive the water mist with water negative ions generated by the water negative ion generating component 2 at the water mist outlet 6 to move to the target area. The target area mainly refers to the air that the user can breathe, so that the water mist with water negative ions can purify the air and improve the user's breathing quality.

[0022] This invention arranges the air outlet duct 12 and the water mist outlet 6 adjacent to each other, making them independent of each other. On the one hand, it can prevent the water mist generated by the water negative ion generating component 2 from entering the fan 11 of the air outlet component 1, thus preventing the electrical and mechanical parts of the fan 11 from getting damp, reducing the failure rate of the fan 11 and improving its durability. This way, the drive system of the fan 11 does not need excessive waterproofing and moisture-proofing treatment, reducing the performance requirements of the fan 11. At the same time, it can also prevent water mist from accumulating inside the air outlet component 1, thereby reducing the risk of bacterial growth and reducing the cleaning frequency. On the other hand, the airflow generated by the air outlet component 1 in the air outlet duct 12 can be used to move the water mist with water negative ions to the target area. This not only moves the water mist to the target area, but also enhances the diffusion effect of the water mist through airflow, effectively increasing the distribution range of water negative ions. This reduces the need for water mist delivery devices with additional energy, and achieves the effect of water negative ions while simplifying the overall structure and reducing energy consumption. In one embodiment, a separator 125 is provided in the air outlet channel 12, which divides the air outlet channel 12 into two relatively independent air outlet channels I 121 and II 122. The air outlet channel II 122 is located between the air outlet channel I 121 and the water mist outlet 6. A negative ion generator 3 is installed inside the air outlet channel I121.

[0023] In this embodiment, refer to the appendix. Figure 1 The negative ion generator 3 is used to generate negative air ions in the air outlet channel I 121. The generated negative air ions will flow out with the air flowing in the air outlet channel 12. At this time, the air outlet channel I 121 flows out with air negative ions, the air outlet channel II 122 flows out with air, and the water mist outlet 6 flows out with water mist containing water negative ions. The flowing air will carry the water mist. Finally, the negative air ions, air and water mist mix in the process of moving to the target area, so that the negative air ions and water negative ions combine, which greatly increases the negative ion content of the target area, while also ensuring the humidity of the target area.

[0024] Meanwhile, at the air outlet 12 and the water mist outlet 6, the air flowing out of the air outlet 122 is positioned between the air flowing out of the air outlet 121 containing negative air ions and the water mist flowing out of the water mist outlet 6 containing negative water ions. This can isolate the water mist from the air outlet 121 at the air outlet 12 and the water mist outlet 6, thus preventing the water mist from entering the air outlet 121 and contacting the negative ion generator 3, and avoiding the water mist affecting the operation and durability of the negative ion generator 3.

[0025] Furthermore, the design of the separator 125 can be used to distribute the airflow of air outlet channel I 121 and air outlet channel II 122, and can regulate the mixing position of negative air ions and water mist, further reducing the possibility of water mist entering air outlet channel I 121 and air outlet channel II 122. In a preferred embodiment, the position of the separator 125 can be adjusted, thereby actively regulating the airflow of air outlet channel I 121 and air outlet channel II 122. The airflow of air outlet channel II 122 is adjusted accordingly based on the amount of water mist generated by the water negative ion generating component 2, ensuring that water mist cannot enter air outlet channel I 121 and air outlet channel II 122 under different water mist amounts.

[0026] In one embodiment, the air outlet assembly 1 includes a fan 11; The air outlet channel 12 includes an air inlet 123 and an air outlet 124, with the air inlet 123 connected to the air outlet 112 of the fan 11. In this embodiment, the air outlet channel 12 is not the air outlet 112 of the fan 11. On the one hand, it can guide the airflow from the fan 11, causing the airflow to flow in a relatively concentrated manner to the target area. On the other hand, the air outlet channel 12 can extend the distance that water mist travels to the fan 11, further increasing the difficulty for water mist to enter the fan 11.

[0027] In one embodiment, reference is made to the appendix. Figure 7 The air outlet channel 12 is a rectangular channel, and the air inlet 123 and air outlet 124 are located on adjacent side walls of the rectangular channel. In this embodiment, since the air inlet 123 and air outlet 124 are not on a straight line, it can further increase the difficulty for water mist to enter the fan 11.

[0028] In one embodiment, reference is made to the appendix. Figure 7 and attached Figure 8 The air outlet assembly 1 also includes an air inlet channel 13 that communicates with the air inlet end 123; The air inlet channel 13 is parallel to the air outlet channel 12, that is, the air supply direction of the air inlet channel 13 is the same as the air supply direction of the air outlet channel 12. The air outlet 112 of the fan 11 is connected to the inlet of the air inlet channel 13.

[0029] In this embodiment, the air from the air outlet 112 of the fan 11 can enter the air outlet 12 through the air inlet 13, and the distance from which the water mist enters the fan 11 can be further extended, thereby further increasing the difficulty for the water mist to enter the fan 11.

[0030] In one embodiment, the air inlet 111 and the air outlet 112 of the fan 11 are perpendicular to each other. In this case, the fan 11 can be a centrifugal fan. The air inlet 111 is equipped with a filter assembly 14, which can filter the flowing air and further improve air quality. Reference Appendix Figure 4 The air outlet channel 12, air inlet channel 13, fan 11 and filter assembly 14 are arranged in a rectangular pattern. Preferably, the air outlet channel 12 and air inlet channel 13 are arranged horizontally at the top, the fan 11 is arranged below the air inlet channel 13, and the filter assembly 14 is arranged below the air outlet channel 12, so as to ensure that the structure of the entire air outlet assembly 1 is compact and reduce the size of the water negative ion mechanism.

[0031] In one embodiment, the water negative ion generating component 2 includes a microporous vibrating plate 23 and a water tank 21 and a mist outlet 22 arranged sequentially. The water tank 21 and the mist outlet 22 share a common side wall, which can reduce the size and facilitate the installation of the microporous vibrating plate 23. The microporous vibrating plate 23 is arranged on the common side wall of the water tank 21 and the mist outlet 22. The microporous vibrating plate 23 can vibrate and break the water in the water tank 21 under electric drive to form a water mist with water negative ions in the mist outlet 22. The mist outlet 6 is provided on the mist outlet chamber 22, so that the mist in the mist outlet chamber 22 can flow out through the mist outlet 6.

[0032] In one embodiment, reference is made to the appendix. Figure 5 and attached Figure 9 The water negative ion mechanism also includes a housing 41 and a sealing element 5; when the water negative ion mechanism is installed on the neck-hanging water negative ion device, the housing 41 is the outer shell of the neck-hanging body 4 in the neck-hanging water negative ion device; wherein the sealing element 5 is used to isolate the water mist outlet 6 on the mist outlet chamber 22 from the inside of the housing 41, and is also used to isolate the water mist outlet 6 on the mist outlet chamber 22 from the air outlet assembly 1. The outer shell 41, the sealing element 5 and the mist outlet 22 are respectively provided with interconnected water mist outlets 6. The water mist with negative water ions generated in the mist outlet 22 passes through the water mist outlet 6 of the mist outlet 22, the water mist outlet 6 of the sealing element 5 and the water mist outlet 6 of the outer shell 41 in sequence and then enters the space outside the outer shell 41. A sealing ring 7 is provided between the outer shell 41 and the sealing element 5, and between the sealing element 5 and the mist outlet 22. The sealing ring 7 is wrapped around the outside of the water mist outlet 6. The sealing element 5 is used to connect the outer shell 41 and the mist outlet 22 to ensure a sealed transition between the water mist outlet 6 on the mist outlet 22 and the water mist outlet 6 on the outer shell 41, preventing water mist from entering other spaces inside the outer shell 41, ensuring the dryness of other components inside the outer shell 41 of the neck hanger body 4, and preventing bacterial growth.

[0033] In this embodiment, based on the separate structure of the mist outlet 22 and the outer shell 41, a sealing element 5 and a sealing ring 7 are added to ensure a sealed transition between the water mist outlet 6 on the mist outlet 22 and the water mist outlet 6 on the outer shell 41. This prevents water mist from entering the interior of the outer shell 41 through the gap between the mist outlet 22 and the outer shell 41, ensuring that the part of the outer shell 41 outside the mist outlet 22 is dry, improving the durability of the components inside the outer shell 41, and preventing the growth of bacteria inside the outer shell 41.

[0034] In addition, the sequential arrangement of the outer shell 41, the seal 5, and the mist outlet 22 simplifies the installation of the mist outlet 22 and the seal 5. The sealing ring 7 not only ensures the sealed transition between the water mist outlet 6 on the mist outlet 22 and the water mist outlet 6 on the outer shell 41, but also ensures a tight connection between the outer shell 41, the seal 5, and the mist outlet 22 during installation. The two sealing rings 7 provide a transition for the connection between the three, thus acting as a buffer element to prevent the seal 5 and the mist outlet 22 from shaking and making noise when the outer shell 41 is under vibration. In one embodiment, reference is made to the appendix. Figure 7 and attached Figure 9 The air outlet duct 12 and the sealing element 5 are integrally formed, which can ensure that the water mist outlet 6 is isolated from the outlet of the air outlet duct 12.

[0035] In one embodiment, a sealing ring mounting groove I221 is provided on the outer wall of the mist outlet chamber 22. The sealing ring 7, located between the sealing element 5 and the mist outlet chamber 22, is fitted into the sealing ring mounting groove I221. After the sealing ring 7 is embedded in the sealing ring mounting groove I221, a portion of the sealing ring 7 protrudes from the opening of the sealing ring mounting groove I221. When the sealing element 5 and the mist outlet chamber 22 are in contact, the protruding portion of the sealing ring 7 abuts against and adheres to the sealing element 5. In this embodiment, by providing the sealing ring mounting groove I221, on the one hand, the fixed position stability of the sealing ring 7 can be improved, preventing it from entering the space of the water mist outlet 6 and affecting the misting and sealing effect. On the other hand, the sealing ring 7 can be fixed in the sealing ring mounting groove I221 before installation, which simplifies the difficulty of disassembling and assembling the sealing ring 7 between the sealing element 5 and the mist outlet chamber 22.

[0036] In one embodiment, the sealing element 5 has a sealing ring mounting groove II 51 on the side near the outer shell 41. The sealing ring 7, located between the outer shell 41 and the sealing element 5, is fitted into the sealing ring mounting groove II 51. After the sealing ring 7 is embedded in the sealing ring mounting groove II 51, a portion of the sealing ring 7 protrudes from the opening of the sealing ring mounting groove II 51. When the outer shell 41 and the sealing element 5 are fitted together, the protruding portion of the sealing ring 7 abuts against and fits against the outer shell 41. In this embodiment, by providing the sealing ring mounting groove II 51, the stability of the fixed position of the sealing ring 7 can be improved, preventing it from entering the space of the water mist outlet 6 and affecting the misting and sealing effect. On the other hand, the sealing ring 7 can be fixed in the sealing ring mounting groove II 51 before installation, which simplifies the difficulty of disassembling and assembling the sealing ring 7 between the outer shell 41 and the sealing element 5.

[0037] In one embodiment, the seal 5 and the mist outlet chamber 22 are detachably fixed by fasteners, which can be bolts or snap-fit ​​fasteners. In this embodiment, the seal 5 is fixed to the mist outlet chamber 22, and then both are fixed inside the outer casing 41, thus simplifying the installation of the seal 5. In an embodiment where the air outlet duct 12 and the seal 5 are integrally formed, the air outlet duct 12 is simultaneously fixed to the mist outlet chamber 22, and then all three are fixed inside the outer casing 41.

[0038] In one embodiment, the mist outlet chamber 22 is detachably fixed to the outer casing 41 by fasteners. Similarly, the fasteners can be bolts or snap-fit ​​fasteners. In this embodiment, the sealing element 5 is first fixed to the mist outlet chamber 22, and then the mist outlet chamber 22 is fixed to the outer casing 41 by fasteners. At this time, the sealing element 5 is not directly fixed to the outer casing 41, but is fixed to the outer casing 41 through the mist outlet chamber 22, thus pressing and fixing the sealing element 5 to the outer casing 41, simplifying the installation of the sealing element 5.

[0039] In one embodiment, the sealing member 5 is provided with a sealing cover 8 that can block or open the water mist outlet 6 on the sealing member 5. The sealing cover 8 can block or open the water mist outlet 6 according to the usage state of the mist outlet chamber 22. In particular, when the mist outlet chamber 22 is not in use, the water mist outlet 6 can be completely blocked to prevent water mist or condensed water in the mist outlet chamber 22 from flowing out of the water mist outlet 6.

[0040] In one embodiment, the sealing cap 8 is made of a flexible material; One end of the sealing cap 8 is hinged to one side of the water mist outlet 6 on the sealing member 5. The sealing cap 8 is provided with a snap-fit ​​structure I81 on the side away from the hinge and close to the water mist outlet 6. The sealing member 5 is provided with a snap-fit ​​structure I52 at the position of the water mist outlet 6. When the sealing cap 8 blocks the water mist outlet 6, the snap-fit ​​structure I 81 and the snap-fit ​​engagement structure I 52 engage. The snap-fit ​​structure I 81 and the snap-fit ​​engagement structure I 52 can be a slot and a block, respectively. When the sealing cap 8 needs to open the water mist outlet 6, simply remove the snap-fit ​​structure I 81 from the snap-fit ​​engagement structure I 52. At this time, the sealing cap 8 can be flipped around the hinge point, allowing it to move away from the water mist outlet 6. In this embodiment, the sealing cap 8 is always fixed to the sealing element 5, preventing it from being lost.

[0041] In a preferred embodiment, a grid mesh 61 is provided on the water mist outlet 6 of the sealing member 5. The grid mesh 61 can support the sealing cover 8 and prevent the sealing cover 8 from moving into the mist outlet chamber 22. In this embodiment, the snap-fit ​​structure I 52 is provided on the grid mesh 61.

[0042] In one embodiment, the sealing cover 8 is disposed on the side opposite to the hinge and on the side opposite to the water mist outlet 6, and the outer shell 41 is disposed on the side opposite to the snap-fit ​​structure I 52, wherein the snap-fit ​​structure II 82 and the snap-fit ​​structure II 411 can be a slot and a block, respectively; when the sealing cover 8 opens the water mist outlet 6, the snap-fit ​​structure II 82 and the snap-fit ​​structure II 411 engage. In this embodiment, when the sealing cover 8 opens the water mist outlet 6, the engagement of the snap-fit ​​structure II 82 and the snap-fit ​​structure II 411 ensures that the sealing cover 8 is always away from the water mist outlet 6, avoiding affecting the mist output of the water mist outlet 6. At the same time, in this embodiment, the sealing cover 8 is always fixed to the sealing member 5, so that the sealing cover 8 will not be lost.

[0043] In one embodiment, the sealing member 5 is provided with an insertion hole 53, and the sealing cover 8 is provided with a hinge block 83 for insertion into the insertion hole 53. A limiting block 84 is provided at the end of the hinge block 83 opposite to the sealing cover 8, and the size of the limiting block 84 is larger than the size of the insertion hole 53; the length of the hinge block 83 is longer than the length of the insertion hole 53. In this embodiment, the hinge block 83 has a strip-shaped structure, which provides a certain amount of movement space for the hinge block 83, and the limiting block 84 can prevent the hinge block 83 from sliding out of the insertion hole 53.

[0044] This utility model also provides a neck-mounted water negative ion device, including a neck-mounted body 4 on which the aforementioned water negative ion mechanism is disposed. Because the aforementioned water negative ion mechanism has a simple and compact structure, it can be well integrated into the neck-mounted body 4 without excessively increasing the wearing burden, ensuring comfortable use. Preferably, the neck-hanging body 4 is a "U"-shaped structure, wherein the arc-shaped part is used to hang on the back of the user's neck, and the straight parts at both ends are used to install the water negative ion mechanism.

[0045] In one embodiment, the air outlet 12 and the water mist outlet 6 are arranged sequentially above the end of the neckband body 4 along its length, that is, at the end of the straight section of the neckband body 4. In this case, the air outlet 12 and the water mist outlet 6 can face the front of the user's nasal cavity, providing purified air to the user. Moreover, in an embodiment where the air outlet 12, air inlet 13, fan 11, and filter assembly 14 are arranged in a rectangular pattern, the air inlet 111 of the fan 11 and the filter assembly 14 are arranged facing the inner side of the neckband body 4, which can provide a larger air intake area and improve the air intake effect.

[0046] The above description is merely an embodiment and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations, modifications, or alterations to the technical solution of this utility model without departing from its scope. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model, without departing from its scope, should fall within the protection scope of this utility model.
