Description
Technical Field
[0001] This utility model relates to the technical field of negative oxygen ion generators, and in particular to a negative oxygen ion generator for air purification. Background Technology
[0002] In existing technologies, a negative ion generator is a device that produces negative ions through methods such as corona discharge, ultraviolet irradiation, or hydrodynamics. Its core function is to release negative ions to improve air quality. It can actively adsorb suspended particulate matter such as dust, smoke, and pollen in the air, causing them to agglomerate and settle, thereby purifying the air.
[0003] A search revealed a utility model patent with Chinese patent publication number CN219980055U, which discloses a negative ion generator housing. The housing has an opening on its front surface, and a limiting frame fixedly connected to the housing surface is located at the front of the opening. Inside the limiting frame are two threaded movable plates, each slidably connected to the limiting frame. Slide grooves are formed inside the housing at both the upper and lower ends of the opening, and adjusting slide plates slidably connected to the opening are slidably connected inside the grooves. Both adjusting slide plates are fixedly connected to the corresponding threaded movable plate surfaces via fixed rods. A bidirectional lead screw passes through the two threaded movable plates and is threadedly connected to the through-hole portion inside the limiting frame. While this utility model allows for adjustment of the opening size and negative ion concentration through components such as a cross-shaped rotating block, limiting frame, and threaded movable plates, the bidirectional lead screw and threaded movement for opening adjustment are problematic. The threaded gaps of the lead screw easily attract dust, hair, and other impurities, significantly increasing thread friction and potentially causing jamming. Utility Model Content

[0014] Compared with the prior art, this utility model provides a negative oxygen ion generator for air purification, which has the following beneficial effects:
[0015] 1. When air purification is required, first connect the high-voltage transformer to the power supply. The high-voltage transformer converts low-voltage electricity into high-voltage electricity and outputs it to the discharge needle. The tip of the discharge needle generates a strong electric field, causing the surrounding air to be slightly ionized. Oxygen molecules capture electrons to generate negative oxygen ions. Then, the opening size is adjusted by rotating the adjustment mechanism to control the concentration of negative oxygen ions. Next, the opening size of the adjustment mechanism is adjusted by fixing the mechanism. Finally, the negative oxygen ions are diffused to the outside of the chamber by the fan. Thus, the adjustment mechanism can avoid airflow turbulence, and the transmission process is reliable and not prone to jamming, ensuring the long-term use of the adjustment function. At the same time, the current opening size of the adjustment mechanism can be known by fixing the mechanism.
[0016] 2. When adjusting the concentration of negative oxygen ions, manually turn the wrench. The wrench drives the rotating ring, which slides within the slot in the housing. Simultaneously, the rotating ring, with the cooperation of the rotating seat, rotates around the central ring. At the same time, the rotating seat rotates around its own axis around the connection point of the connecting seat. As the rotating ring rotates, it drives the guide post to rotate synchronously. The guide post slides within the guide groove of the connecting rod, causing the connecting rod to swing. The connecting rod is fixed to the rotating rod, which in turn pushes the rotating rod to rotate around the connection point of the central ring, transmitting power to the blades. This drives the blades to rotate synchronously, thus achieving synchronous movement of multiple blades. The regular shape of the opening avoids airflow turbulence, resulting in more uniform diffusion of negative oxygen ions. Furthermore, the cooperation of multiple components such as the connecting ring, central ring, and rotating seat ensures reliable transmission and prevents jamming, guaranteeing the long-term use of the adjustment function.
[0017] 3. When the fixing pin is located in the middle position hole of the gear box, the adjustment mechanism is in the closed state. When it is necessary to adjust the opening of the adjustment mechanism, pull the handle outward so that the handle slides along the connection of the compression box. The fixing pin moves with the handle. At this time, the handle slides along the inner wall of the limit block. At the same time, it cooperates with the compression spring on one side of the inner wall of the compression box. The fixing pin gradually moves away from the position hole of the gear box to unlock. Then, turn the handle to open the adjustment mechanism to a certain opening and align the fixing pin with the position hole of the next gear box. At this time, release the handle. The spring pushes the fixing pin to reset and puts the fixing pin into the corresponding position hole of the gear box. Thus, the position holes on the gear box correspond to different opening sizes of the adjustment mechanism. When the fixing pin is inserted into different positions, the user can know the opening size of the adjustment mechanism through the gear box, which improves the opening adjustment accuracy.
[0018] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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, they should not be construed as limitations on this utility model.
[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0028] A negative ion generator for air purification, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the device includes a housing 1, with a fan 2 embedded in the top of the housing 1, a high-voltage transformer 3 fixed to the top of the inner wall of the housing 1, an aluminum plate 4 fixed to the bottom of the inner wall of the housing 1, a discharge needle 5 fixed to the top of the aluminum plate 4, a base 6 fixedly connected to the inner wall of the housing 1, an adjustment mechanism 7 set on the top of the base 6, a fixing mechanism 8 set on one side of the housing 1, and a slot opened on one side of the housing 1. The high-voltage transformer 3 is model KXA220-2000, and the discharge needle 5 is model YW1.
[0029] When air purification is needed, the high-voltage transformer 3 is first connected to the power supply. The high-voltage transformer 3 converts low-voltage electricity into high-voltage electricity and outputs it to the discharge needle 5. The tip of the discharge needle 5 generates a strong electric field, which ionizes the surrounding oxygen molecules, and oxygen molecules capture electrons to generate negative oxygen ions.
[0030] The opening size is then adjusted by rotating the adjustment mechanism 7 to control the concentration of negative oxygen ions. Next, the opening size of the adjustment mechanism 7 is adjusted by fixing mechanism 8. Finally, the negative oxygen ions are diffused to the outside of the cabinet 1 by fan 2. Thus, the adjustment mechanism 7 can avoid airflow turbulence, and the transmission process is reliable and not prone to jamming, ensuring the long-term use of the adjustment function. At the same time, the current opening size of the adjustment mechanism 7 can be known by fixing mechanism 8.
[0031] In order to adjust the concentration of negative oxygen ions output, such as Figure 3 and Figure 4 As shown, the adjusting mechanism 7 includes a connecting ring 701, a central ring 702, a central block 703, blades 704, a rotating ring 705, a rotating rod 706, a connecting rod 707, a guide post 708, a connecting seat 709, a rotating seat 710, and a wrench 711. The connecting ring 701 is fixedly connected to the top of the base 6, and a groove is formed on the outer surface of the connecting ring 701. The central ring 702 is fixedly connected to the bottom of the connecting ring 701. The central block 703 is fixedly connected to the inner wall of the central ring 702 by a crossbar. Three or more blades 704 are rotatably connected to the outer surface of the central block 703. Three connecting seats 709 are fixedly connected to the outer wall of the central ring 702. The rotating seat 710 is rotatably connected to the connecting seat 705. On both sides of the inner wall of 09, the rotating ring 705 is fixed to the outer surface of the rotating seat 710, the rotating rod 706 is rotatably connected to the outer surface of the central ring 702, and the rotating rod 706 passes through the outer surface of the central ring 702 and is fixedly connected to the blade 704. The connecting rod 707 is fixed to one side of the rotating rod 706, and a guide groove is provided on one side of the connecting rod 707. The guide post 708 is slidably connected to the inner wall of the guide groove provided by the connecting rod 707, and the guide post 708 is fixedly connected to the rotating ring 705. The wrench 711 is fixed to the outer surface of the rotating ring 705, and the wrench 711 is slidably engaged with the sliding groove provided by the connecting ring 701. The wrench 711 passes through one side of the inner wall of the housing 1, and the wrench 711 is fixedly connected to the rotating ring 705.
[0032] When it is necessary to adjust the concentration of negative oxygen ions, manually turn the wrench 711. The wrench 711 drives the rotating ring 705. The wrench 711 slides in the slot opened in the box 1. At the same time, the rotating ring 705 makes a circular motion around the central ring 702 with the cooperation of the rotating seat 710. Meanwhile, the rotating seat 710 rotates around its own axis with the connection of the connecting seat 709.
[0033] When the rotating ring 705 rotates, it drives the guide post 708 to rotate synchronously. At the same time, the guide post 708 slides in the guide groove of the connecting rod 707, causing the connecting rod 707 to swing. The connecting rod 707 is fixed to the rotating rod 706, which in turn pushes the rotating rod 706 to rotate around the connection point of the central ring 702, and transmits the power to the blades 704, thereby driving the blades 704 to rotate synchronously. In this way, multiple blades 704 move synchronously, and the opening shape is regular, which can avoid airflow turbulence and make the diffusion of negative oxygen ions more uniform. At the same time, the cooperation of multiple components such as the connecting ring 701, the central ring 702, and the rotating seat 710 ensures reliable transmission and prevents jamming, thus ensuring the long-term use of the adjustment function.
[0034] In order to make it clear to the user the size of the opening adjustment, such as Figure 5 As shown, the fixing mechanism 8 includes a gear box 801, a limiting block 802, a fixing pin 803, a compression box 804, a spring 805, and a handle 806. The gear box 801 is fixedly connected to one side of the housing 1, the limiting block 802 is fixedly connected to the top of the wrench 711, the fixing pin 803 is slidably connected to the inner wall of the limiting block 802, the compression box 804 is fixedly connected to one side of the limiting block 802, one end of the spring 805 is fixedly connected to one side of the fixing pin 803, the handle 806 is slidably connected to one side of the compression box 804, and the spring 805 is sleeved on the outer wall of the handle 806. The end of the spring 805 away from the fixing pin 803 is fixedly connected to one side of the inner wall of the compression box 804, and the handle 806 is fixedly connected to one side of the fixing pin 803.
[0035] When the fixing pin 803 is located in the middle gear hole of the gear box 801, the adjusting mechanism 7 is in the closed state. When it is necessary to adjust the opening of the adjusting mechanism 7, pull the handle 806 outward so that the handle 806 slides along the connection of the compression box 804. The fixing pin 803 moves together with the handle 806. At this time, the handle 806 slides along the inner wall of the limiting block 802. At the same time, it cooperates with the compression spring 805 on one side of the inner wall of the compression box 804. The fixing pin 803 gradually moves away from the gear hole of the gear box 801 to unlock.
[0036] Next, by turning the handle 806 and the wrench 711, the adjusting mechanism 7 opens a certain opening and the fixing pin 803 is aligned with the gear position hole of the next gear box 801. At this time, the handle 806 is released, and the spring 805 pushes the fixing pin 803 to reset, so that the fixing pin 803 enters the corresponding gear position hole of the gear box 801. Thus, the gear position hole on the gear box 801 corresponds to different opening sizes of the adjusting mechanism 7. When the fixing pin 803 is inserted into different positions, the user can know the opening size of the adjusting mechanism 7 through the gear box 801, thereby improving the opening adjustment accuracy.
[0037] Workflow: When air purification is required, first connect the power supply to the high-voltage transformer 3. The high-voltage transformer 3 converts low-voltage electricity into high-voltage electricity and outputs it to the discharge needle 5. The tip of the discharge needle 5 generates a strong electric field, which ionizes the surrounding oxygen molecules, and oxygen molecules capture electrons to generate negative oxygen ions.
[0038] The opening size is then adjusted by rotating the adjustment mechanism 7 to control the concentration of negative oxygen ions. Next, the opening size of the fixing mechanism 8 is adjusted, and finally, the negative oxygen ions are diffused to the outside of the cabinet 1 by the fan 2.
[0039] When it is necessary to adjust the concentration of negative oxygen ions, manually turn the wrench 711. The wrench 711 drives the rotating ring 705. The wrench 711 slides in the slot opened in the box 1. At the same time, the rotating ring 705 makes a circular motion around the central ring 702 with the cooperation of the rotating seat 710. Meanwhile, the rotating seat 710 rotates around its own axis with the connection of the connecting seat 709.
[0040] When the rotating ring 705 rotates, it drives the guide post 708 to rotate synchronously. At the same time, the guide post 708 slides in the guide groove of the connecting rod 707 and drives the connecting rod 707 to swing. The connecting rod 707 is fixed to the rotating rod 706, which in turn pushes the rotating rod 706 to rotate around the connection of the central ring 702 and transmits the power to the blade 704, thereby driving the blade 704 to rotate synchronously.
[0041] When the fixing pin 803 is located in the middle gear hole of the gear box 801, the adjusting mechanism 7 is in the closed state. When it is necessary to adjust the opening of the adjusting mechanism 7, pull the handle 806 outward so that the handle 806 slides along the connection of the compression box 804. The fixing pin 803 moves together with the handle 806. At this time, the handle 806 slides along the inner wall of the limiting block 802. At the same time, it cooperates with the compression spring 805 on one side of the inner wall of the compression box 804. The fixing pin 803 gradually moves away from the gear hole of the gear box 801 to unlock.
[0042] Next, by turning the handle 806 and the wrench 711, the adjusting mechanism 7 opens a certain opening and the fixing pin 803 is aligned with the gear hole of the next gear box 801. At this time, the handle 806 is released and the spring 805 pushes the fixing pin 803 to reset, so that the fixing pin 803 enters the corresponding gear hole of the gear box 801.
[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
