Description

Technical Field

[0001] This utility model relates to cleaning devices, and more particularly to a negative ion discharge needle cleaning device. Background Technology

[0002] In the field of negative ion generation technology, the high-voltage discharge needle plays a crucial role as a key component. Negative ions have wide applications in many fields such as air purification and healthcare, and the stability of the high-voltage discharge needle's performance directly determines the efficiency and quality of negative ion generation.

[0003] Currently, high-voltage discharge needles used to generate negative ions face serious problems in actual operation. With prolonged continuous operation, the surface of the high-voltage discharge needle is easily contaminated with various pollutants. These pollutants come from a wide range of sources, such as dust particles suspended in the surrounding air and oily contaminants. During the discharge process, due to electrostatic adsorption and other effects, they gradually accumulate on the surface of the discharge needle.

[0004] Once the surface of the discharge needle is contaminated, its performance will be significantly affected. Firstly, the presence of contaminants alters the electric field distribution of the discharge needle, making the discharge process unstable and consequently reducing the efficiency of negative ion generation. Devices that were originally capable of efficiently generating large numbers of negative ions will experience a significant drop in negative ion production after the discharge needle becomes contaminated, failing to meet the needs of practical applications. For example, in indoor air purification, the negative ion concentration will be difficult to reach the ideal level, greatly diminishing the air purification effect. Secondly, contaminant buildup may also cause abnormal localized discharges, increasing the energy consumption of the device and potentially damaging other components, thus shortening the overall lifespan of the equipment.

[0005] Current solutions mostly involve manual, periodic disassembly and cleaning, but this method has many drawbacks. Manual cleaning not only consumes significant manpower and time, but the disassembly and reassembly process can easily damage the high-voltage discharge needle and related components, or result in incomplete restoration, further affecting equipment performance. Simultaneously, frequent manual intervention increases equipment downtime, reducing its efficiency and failing to meet the needs of locations requiring a continuous supply of negative ions.

[0054] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the embodiments will be briefly described below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0055] In describing embodiments of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" express orientations or positional relationships based on the orientations or positional relationships shown in the relevant drawings. They are only for the convenience of describing 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, the above terms should not be construed as limitations on this utility model.

[0056] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described in detail here, but the embodiments of the present invention are not limited to the following embodiments.

[0057] Combination Figure 1 and Figure 2As shown, according to one embodiment of the present invention, a negative ion discharge needle cleaning device includes: a fixed support 1.1, a movable support 1.2, a linear drive assembly 1.3, and a cleaning component 1.4. In this embodiment, the movable support 1.2 is slidably connected to the fixed support 1.1; the movable support 1.2 is connected to the linear drive assembly 1.3; furthermore, the cleaning component 1.4 is provided with a cleaning channel 1.41 for the discharge needle to pass through; thereby, the movable support 1.2 is driven by the linear drive assembly 1.3 to move coaxially relative to the fixed support 1.1, thereby causing the cleaning component 1.4 to move coaxially relative to the installed discharge needle, so that the inner surface of the cleaning channel 1.41 slides into contact with the outer surface of the discharge needle to clean the outer surface of the discharge needle; wherein, when the cleaning component 1.4 is installed on the fixed support 1.1, the discharge needle can be installed on the movable support 1.2; when the cleaning component 1.4 is installed on the movable support 1.2, the discharge needle can be installed on the fixed support 1.1.

[0058] Combination Figure 2 , Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the cleaning component 1.4 is provided with an elastic cleaning part 1.4a; wherein, a cleaning channel 1.41 is arranged on the elastic cleaning part 1.4a, and the cleaning channel 1.41 penetrates the body of the elastic cleaning part 1.4a.

[0059] Combination Figure 2 , Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the cleaning channel 1.41 is a variable-diameter channel with a variable diameter along its axial direction. The diameter of the cleaning channel 1.41 can be set to gradually decrease. Therefore, based on the gradually decreasing radial dimension, the cleaning channel 1.41 can adapt to the dimensional changes of the outer surface of the discharge needle during its movement relative to the discharge needle. This allows the cleaning channel 1.41 in the cleaning component 1.4 of the present invention to fully conform to the outer surface of the discharge needle, enabling thorough sliding wiping of the outer surface of the discharge needle, which is more beneficial to ensuring the cleaning effect of the present invention. Furthermore, through the contact between the cleaning channel 1.41 and the discharge needle, the inner surface of the cleaning channel 1.41 and the outer surface of the discharge needle generate friction, thereby achieving the cleaning of the outer surface of the discharge needle. The radial dimension of the cleaning channel 1.41 can be smaller than the radial dimension of the outer surface of the discharge needle. Thus, during the sliding fit, the cleaning channel 1.41 can fully conform to the outer surface of the discharge needle based on its elastic deformation, thereby improving the wiping effect on the surface and making the cleaning effect of this invention better.

[0060] In this embodiment, the elastic cleaning part 1.4a is made of wear-resistant and elastic materials such as rubber and silicone, thereby enabling the cleaning part 1.4 of this invention to have a long service life and high reliability.

[0061] Combination Figure 2 , Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the cleaning component 1.4 includes: an annular body 1.4b; wherein, the elastic cleaning part 1.4a is coaxially and fixedly connected to the front end of the annular body 1.4b. In this embodiment, the front end of the elastic cleaning part 1.4a is provided with an annular connecting part, thereby achieving a fixed connection with the front end of the annular body 1.4b through the outer edge of the annular connecting part. Thus, the cleaning component 1.4 can be installed by fitting the annular body 1.4b onto the front end of a corresponding structure (such as a fixed support 1.1 or a movable support 1.2).

[0062] In this embodiment, to ensure the reliability of the installation of the cleaning component 1.4, an annular fitting groove can be provided on the outer surface of the elastic cleaning part 1.4a. Thus, an annular connecting structure can be provided on the corresponding structure. When the annular body 1.4b is sleeved on the outer side of the end of the corresponding structure, the annular fitting groove on the outer surface of the elastic cleaning part 1.4a can be further fitted with the annular connecting structure of the corresponding structure, thereby effectively ensuring the reliability and stability of the installation.

[0063] In this embodiment, the annular body 1.4b and the elastic cleaning part 1.4a can be integrated to facilitate molding and reduce production costs. Specifically, to facilitate integrated molding, the annular body 1.4b and the elastic cleaning part 1.4a can be made of the same material.

[0064] Combination Figure 1 and Figure 2 As shown, according to one embodiment of this utility model, the fixed support 1.1 and the movable support 1.2 are coaxially sleeved together. Therefore, the coaxial arrangement of the fixed support 1.1 and the movable support 1.2 effectively ensures the installation accuracy of the discharge needle while achieving reliable cleaning of the discharge needle. In this embodiment, to ensure reliable installation between them, the fixed support 1.1 and the movable support 1.2 can be respectively configured as circular tube structures, thereby easily and conveniently achieving the coaxiality of the installation between the fixed support 1.1 and the movable support 1.2.

[0065] like Figure 1As shown, according to one embodiment of the present invention, the linear drive assembly 1.3 includes: a linear driver 1.31 and a transition connector 1.32 connected to the telescopic end of the linear driver 1.31; wherein, the transition connector 1.32 can be configured as a long strip structure, and the transition connector 1.32 is arranged perpendicularly to the telescopic end of the linear driver 1.31; the movable support 1.2 is connected perpendicularly to the transition connector 1.32; thus, the linear movement of the telescopic end of the linear driver 1.31 can be directly transmitted to the movable support 1.2 through the conduction effect of the transition connector 1.32, thereby achieving the corresponding erasing effect.

[0066] Furthermore, the connection points between the movable support 1.2 and the transition connector 1.32 are staggered from the connection points between the transition connector 1.32 and the linear actuator 1.31. This staggered arrangement effectively avoids interference between the structures, facilitating the installation and use of this design. In addition, the staggered arrangement allows for the arrangement of multiple movable supports 1.2 along the length of the transition connector 1.32, enabling the cleaning of discharge needles mounted on different fixed supports 1.1. This significantly improves the flexibility and cleaning effect of this invention and makes it more suitable for installations with multiple discharge needles.

[0067] Combination Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, the transition connector 1.32 is provided with a drive connection structure 1.32a for connecting to the telescopic end of the linear actuator 1.31; wherein, the drive connection structure 1.32a includes: a fitting 1.32a1 and a pin positioning member 1.32a2; in this embodiment, the fitting 1.32a1 is provided with a first through hole 1.32a11 for the pin to pass through; the pin positioning member 1.32a2 is provided with a second through hole 1.32a21 for the pin to pass through; correspondingly, the second through hole 1.32a21 is arranged opposite to the first through hole 1.32a11.

[0068] In this embodiment, the fitting 1.32a1 can be configured as a plate-like structure, and the first through hole 1.32a11 provided thereon can be configured as a linear hole, thereby facilitating the pin to pass through the first through hole 1.32a11 on the fitting 1.32a1. Correspondingly, the second through hole 1.32a21 is configured as a through hole penetrating the pin positioning member 1.32a2, and its cross-sectional shape and size are matched with the corresponding pin, thereby achieving the positioning and installation of the pin, thus ensuring the installation accuracy and stability of this utility model.

[0069] like Figure 7As shown, according to one embodiment of the present invention, the telescopic end of the linear actuator 1.31 is provided with a fitting structure 1.311 and a third through hole 1.312 arranged radially along the telescopic end; wherein the fitting structure 1.311 is fitted and connected to the fitting member 1.32a1; the first through hole 1.32a11, the second through hole 1.32a21, and the third through hole 1.312 are connected, and the second through hole 1.32a21 and the third through hole 1.312 are arranged coaxially. In this embodiment, the fitting structure 1.311 can be set as a groove that matches the fitting member 1.32a1, and when the second through hole 1.32a21 and the third through hole 1.312 are coaxial, the correspondingly installed pin can easily pass through the third through hole 1.312, so as to achieve the installation accuracy and reliability between the telescopic end of the linear actuator 1.31 and the transition connector 1.32, thereby improving the driving accuracy and response timeliness of the present invention.

[0070] Combination Figure 1 , Figure 8 and Figure 9 As shown, according to one embodiment of the present invention, the negative ion discharge needle cleaning device further includes: a fixed support mounting base 1.5 and a drive mounting base 1.6; wherein, the fixed support mounting base 1.5 is generally plate-shaped, thereby, the fixed support member 1.1 is fixedly connected to one side of the fixed support mounting base 1.5, and the drive mounting base 1.6 is detachably mounted on the other side of the fixed support mounting base 1.5. In this embodiment, two fixed support members 1.1 are symmetrically arranged, and correspondingly, movable support members 1.2 are arranged one-to-one with the fixed support members 1.1. Thus, based on a unified linear drive assembly 1.3, unified driving of the movable support members 1.2 can be achieved, thereby achieving a synchronous cleaning effect.

[0071] Furthermore, the linear drive assembly 1.3 is detachably connected to the drive mounting base 1.6; wherein, a positioning connecting post for positioning and installing the drive mounting base 1.6 is provided on the side of the fixed support mounting base 1.5, thereby corresponding positioning mounting holes can be provided on the fixed support mounting base 1.5, and the precise positioning of the drive mounting base 1.6 can be achieved by the mutual cooperation of the positioning connecting post and the positioning mounting hole. Furthermore, by providing threaded holes on the positioning connecting post and using threaded fasteners to screw them in, the drive mounting base 1.6 can be locked on the fixed support mounting base 1.5.

[0072] Furthermore, the linear actuator 1.31 can be connected to the drive mounting base 1.6 by means of suspension. The drive mounting base 1.6 has a linear through hole, and the linear actuator 1.31 has a threaded hole. A threaded connector passing through the linear through hole and the threaded hole secures the linear actuator 1.31 to the drive mounting base 1.6. In this embodiment, by providing a linear through hole in the drive mounting base 1.6, the position of the linear actuator 1.31 can be easily and flexibly adjusted. This effectively improves the installation accuracy of the linear actuator 1.31, thus enhancing the operational reliability and stability of this invention.

[0073] Combination Figure 1 and Figure 8 As shown, according to one embodiment of the present invention, the fixed support mounting base 1.5 is provided with a positioning guide structure 1.51; wherein, the positioning guide structure 1.51 and the drive mounting base 1.6 are located on the same side of the fixed support mounting base 1.5; in this embodiment, the positioning guide structure 1.51 is located below the drive mounting base 1.6, and correspondingly, the transition connector 1.32 is provided with a guide through hole 1.32b penetrating its body; thereby, the guide through hole 1.32b and the positioning guide structure 1.51 can be coaxially slid. In this embodiment, the positioning guide structure 1.51 can be set in multiple ways (such as two or three). Correspondingly, the guide through holes 1.32b on the transition connector 1.32 can be set one-to-one with the positioning guide structure 1.51. Thus, the positioning guide structure 1.51 and the guide through holes 1.32b are arranged at intervals to achieve balanced support for the transition connector 1.32, so as to achieve reliable and accurate reciprocating operation, effectively ensuring the installation accuracy and coaxiality of the discharge needle, eliminating the influence of the discharge needle during the cleaning process, and further benefiting the reliable and stable operation of this utility model.

[0074] Combination Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, according to one embodiment of the present invention, the fixed support mounting base 1.5 is provided with a shielding member 1.52; wherein, the shielding member 1.52 is a cylindrical structural member, and it is located on the same side of the fixed support member 1.1 on the fixed support mounting base 1.5; in this embodiment, the shielding member 1.52 and the fixed support member 1.1 are coaxially arranged on the outside of the fixed support member 1.1, and the shielding member 1.52 and the fixed support member 1.1 are spaced apart. In this embodiment, the shielding member 1.52 has a certain axial length to surround the fixed support member 1.1, which can effectively prevent dust and other particles in the outside air from falling directly onto the discharge needle, which is more beneficial to ensuring the cleanliness of the surface of the discharge needle after cleaning.

[0075] In this embodiment, the fixed support 1.1 can be fixedly supported inside the shield 1.52 based on the connecting rib.

[0076] like Figure 2 As shown, according to one embodiment of this utility model, the cleaning component 1.4 is installed at the front end of the fixed support component 1.1, while the discharge needle is installed at the front end of the movable support component 1.2. Therefore, during the movement of the movable support component 1.2 driven by the linear drive assembly 1.3, the discharge needle can move relative to the cleaning channel 1.41 of the cleaning component 1.4, thereby achieving a cleaning effect on the surface of the discharge needle. See also... Figure 10 The discharge needle can be coaxially connected to the movable support 1.2 based on the discharge needle fixing member 1.2a. The discharge needle fixing member 1.2a includes a circular fixing member 1.2a1 and a plurality of fixing legs 1.2a2 evenly spaced outwards along the circumference of the circular fixing member 1.2a1. The fixing legs 1.2a2 extend outwards at an angle away from the circular fixing member 1.2a1. Furthermore, the discharge needle can be coaxially mounted at the center of the circular fixing member 1.2a1. Correspondingly, by installing the discharge needle fixing member 1.2a inside the movable support 1.2, the discharge needle can be securely fixed to the movable support 1.2 based on the elastic force between the fixing legs 1.2a2 and the sidewall of the movable support 1.2.

[0077] In this embodiment, a front baffle can be further provided on the movable support member 1.2, and a positioning hole for the discharge needle to pass through is provided in the middle of the front baffle. Thus, the discharge needle can achieve precise limitation of coaxiality based on the combined structure of the annular fixing member 1.2a1 and the front baffle of the support member.

[0078] According to another embodiment of the present invention, the cleaning component 1.4 is installed at the front end of the movable support component 1.2, while the discharge needle is installed at the front end of the fixed support component 1.1. In this arrangement, the movable support component 1.2 is located on the front side of the fixed support component 1.1 and is sleeved on the outside of the fixed support component 1.1. Thus, during the movement of the movable support component 1.2 driven by the linear drive assembly 1.3, the cleaning component 1.4 can move relative to the discharge needle to achieve a cleaning effect on the surface of the discharge needle. In this embodiment, to avoid the influence of the connecting ribs around the fixed support component 1.1, the movable support component 1.2 can be configured as a cylindrical body with sufficient axial length, and a linear clearance groove corresponding to the connecting ribs is machined on the movable support component 1.2 according to its cleaning stroke, thereby achieving reliable and stable operation of the movable support component 1.2.

[0079] Furthermore, the discharge needle can be coaxially connected to the fixed support 1.1 based on the discharge needle fixing member 1.2a, wherein the discharge needle fixing member 1.2a is the same as the aforementioned arrangement, and will not be repeated here.

[0080] Furthermore, since the front end of the movable support 1.2 is used to install the cleaning component 1.4, the front end of the movable support 1.2 can be matched with the cleaning component 1.4 in the same way as described above, and will not be repeated here. As for the fixed support 1.1, which requires the installation of the discharge needle fixing component 1.2a, to facilitate the stable and reliable installation and extension of the discharge needle, the opening at the front end of the fixed support 1.1 is correspondingly matched with the discharge needle to achieve precise control over the coaxiality of the discharge needle.

[0081] According to another embodiment of the present invention, the linear driver 1.31 is implemented using a motor capable of outputting linear motion (such as a linear motor, linear stepper motor, etc.).

[0082] The above content is merely an example of a specific solution of this utility model. For the equipment and structures not described in detail, it should be understood that they are implemented using common equipment and methods already available in the field.

[0083] The above description is merely one solution of this utility model and is not intended to limit it. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
