Description

Technical Field

[0001] This disclosure relates to the field of electronic component cleaning technology, and more specifically, to a nozzle for electronic components, an airflow cleaning device, and an optical module cleaning device. Background Technology

[0002] With the miniaturization and high-density integration of optical communication equipment, electronic components such as optical modules and connectors typically form relatively narrow mounting slots. During production or use, dust particles in the air can easily enter the mounting slots and adhere to the surfaces of electrical connection terminals, optical interfaces, or heat dissipation structures. This can not only affect the stability of optical signal transmission but also lead to poor contact, reduced heat dissipation performance, and decreased device reliability. Therefore, it is necessary to clean and maintain the mounting slots.

[0003] In existing technologies, cleaning the inside of the mounting slot typically involves methods such as air gun blowing, brush wiping, or vacuuming. Air gun blowing, which uses compressed gas to blow dust off the slot surface, is convenient, but due to the narrowness and depth of the mounting slot, airflow can easily create turbulence, making it difficult to cover the bottom and deeper areas. The blown-up dust tends to float and redeposit, even spreading to surrounding electronic components, affecting cleaning effectiveness. While contact cleaning methods like brushing can remove adhering particles to some extent, they can cause mechanical wear on the delicate structures inside the mounting slot and are unsuitable for smaller slots. As for vacuuming, the limited opening of the mounting slot makes it difficult to create a stable airflow channel using only external negative pressure, hindering the effective removal of deep-seated dust.

[0004] Therefore, how to construct a stable airflow channel within a limited mounting slot to achieve efficient cleaning has become an urgent problem to be solved in the cleaning process of small electronic slots such as optical modules.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure. Summary of the Invention

[0006] The purpose of this disclosure is to provide a nozzle for electronic components, an airflow cleaning device, and an optical module cleaning device to solve the technical problem that existing cleaning methods are unable to efficiently clean the narrow mounting slots of electronic components.

[0007] Other features and advantages of this disclosure will become apparent from the following detailed description, or may be learned in part from practice of this disclosure.

[0008] According to one aspect of this disclosure, a nozzle for electronic components is provided, comprising: An inner core component, wherein the inner core component is provided with an air intake channel; An outer sleeve is fitted over the inner core and forms an exhaust channel with the outer wall of the inner core. The inlet of the exhaust channel is connected to the outlet of the intake channel through the mounting slot of the electronic component. One end of the outer casing matches the slot profile of the electronic component, and one end of the outer casing has an exhaust groove through which the inner core component passes.

[0009] In some embodiments of this disclosure, the air intake channel extends along the insertion direction, and one end of the outer sleeve is perpendicular to the insertion direction, forming a first end face; the exhaust groove is formed on the first end face and extends along the insertion direction.

The third end face is inclined, and the fourth end face is parallel to the insertion direction. The fourth end face is connected to the inner core body through a fifth end face, which is also inclined.

[0012] In some embodiments of this disclosure, the inner core component includes an inner core inlet portion and an inner core body arranged sequentially along the insertion direction; the other end of the outer sleeve is provided with an inlet positioning groove corresponding to the position of the inner core inlet portion, and the inlet positioning groove and the exhaust groove are connected at the communication port to form the exhaust channel; The inner core inlet is inserted into the inlet positioning groove; the inner core body passes through the connecting port and extends into the exhaust groove, and along the insertion direction, the projection of the connecting port is not completely covered by the inner core inlet.

[0013] In some embodiments of this disclosure, the inner core inlet includes a first inlet and a second inlet arranged sequentially along the insertion direction, wherein the second inlet abuts against the bottom wall of the inlet positioning groove; Along the insertion direction, the projection of the first inlet portion not covered by the second inlet portion at least partially coincides with the connecting port, so that an exhaust gap is formed between the first inlet portion and the bottom wall of the inlet positioning groove. The groove wall of the inlet positioning groove is also provided with an outlet groove. The exhaust groove, the connecting port, the exhaust gap and the outlet groove are sequentially connected to form the exhaust channel.

[0014] In some embodiments of this disclosure, the first inlet includes a positioning surface and a guide slope arranged sequentially along the insertion direction. The positioning surface is parallel and fits against the bottom wall of the inlet positioning groove, and the guide slope extends obliquely from the positioning surface to the second inlet in the insertion direction.

[0015] In some embodiments of this disclosure, the outer kit is further provided with a first positioning component, the first positioning component including two first positioning members respectively disposed on both sides of the inner core, the first positioning members extending along a first direction perpendicular to the insertion direction.

[0016] In some embodiments of this disclosure, the inner core body of the inner core component includes a sixth end face disposed perpendicular to the first direction, and the first positioning component includes a positioning plane, the positioning plane being at least partially abutting against the sixth end face.

[0017] In some embodiments of this disclosure, the outer sleeve has a threaded hole corresponding to the position of the first positioning member, the outer wall of the first positioning member has threads, and the first positioning member is threadedly connected to the threaded hole.

[0018] In some embodiments of this disclosure, a positioning mounting groove is provided at one end of the first positioning member away from the inner core body, and a second positioning component is provided in the positioning mounting groove; the second positioning component includes a second positioning member threadedly connected to the positioning mounting groove, and a clamping member is installed on the second positioning member, the clamping member being offset from the axis of the second positioning member.

[0019] In some embodiments of this disclosure, the sixth end face is provided with an arc surface, the sixth end face includes an end face edge area that contacts the connected end face and an arc surface area located between the two end face edge areas; the clamping member abuts against the end face edge area, and the first positioning member abuts against the arc surface area.

[0020] According to another aspect of this disclosure, an airflow cleaning device is provided, including an air source and the above-described nozzle for electronic components, the air source being in communication with the air intake channel.

[0021] According to another aspect of this disclosure, a light module cleaning device is provided, including an air source and the above-described nozzle for electronic components, wherein the air source is in communication with the air inlet channel.

[0022] As can be seen from the above technical solutions, the nozzle for electronic components, the airflow cleaning device, and the optical module cleaning device in the exemplary embodiments of this disclosure have at least the following advantages and positive effects: The nozzle, airflow cleaning device, and optical module cleaning device provided in this application for electronic components are equipped with an air inlet channel in the inner core component. Gas can be directly delivered to the inside of the mounting slot through the air inlet channel, allowing the airflow to penetrate deeper into the internal area of ​​the electronic component mounting slot, thereby improving the coverage of dust accumulation areas at the bottom and deep within the slot. Simultaneously, an outer sleeve is fitted over the inner core component, forming an exhaust channel with the outer wall of the inner core component. This allows the gas sprayed into the mounting slot to carry away dust along the exhaust channel, thus creating a relatively continuous airflow path inside the mounting slot. This avoids the problem of dust being blown up but remaining in the slot or redepositing, thereby improving dust removal efficiency. Furthermore, the inlet of the exhaust channel is connected to the outlet of the air inlet channel through the electronic component mounting slot, allowing the airflow sprayed into the slot to form a flow direction from intake to exhaust within the slot. This reduces the formation of disordered turbulence in the confined space, facilitating the removal of dust from the mounting slot in a predetermined direction. In summary, by cooperating with the inner core component, the outer casing, and the exhaust channel formed between them, the nozzle can form a stable directional airflow circulation path within a limited space after being inserted into the mounting slot of the electronic component. This solves the problems of insufficient airflow coverage, difficulty in removing dust, and secondary dust deposition in existing cleaning methods, achieving the technical effect of efficient cleaning of the narrow mounting slot of electronic components.

Detailed Implementation

[0027] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] In the description of this application, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0029] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1: This embodiment provides a nozzle for electronic components, applicable to cleaning scenarios involving optical modules, optoelectronic connectors, server interface modules, communication equipment slots, and other electronic components with elongated cavity structures. In existing technologies, air guns are typically used to directly blow air into the mounting slots (i.e., elongated cavity structures) for cleaning. However, after compressed air enters the mounting slot, due to the limited internal space and lack of a stable exhaust path, the airflow easily forms disordered turbulence within the slot. This results in dust being merely blown away from its original attachment point without effectively exiting the slot, and some dust may even re-deposit inside, affecting the overall cleaning effect. Simultaneously, for small, complex electronic component mounting slots, traditional brushes or wiping tools struggle to penetrate deeply and are prone to contact with internal precision structures, causing mechanical damage. Therefore, this embodiment proposes a nozzle for electronic components to improve the cleaning efficiency and quality of the mounting slots.

[0031] It should be noted that the optical module in this embodiment can be an SFP optical module, a QSFP optical module, a QSFP-DD optical module, an OSFP optical module, or other optical communication modules, and this application does not make any specific limitations on it.

[0032] like Figures 1 to 4As shown, a nozzle for electronic components includes an inner core 100 and an outer casing 200. The inner core 100 is provided with an air inlet channel 101. The air inlet channel 101 is used to communicate with an external air source to deliver compressed gas into the mounting slot of the electronic component. The air inlet channel 101 mentioned here refers to a channel structure formed inside the inner core 100 for airflow. It can be a through-hole structure or other flow channel structure capable of airflow delivery; this embodiment does not limit this.

[0033] The outer casing 200 is fitted over the inner core 100 and forms an exhaust channel 201 with the outer wall of the inner core 100. The inlet of the exhaust channel 201 is connected to the outlet of the intake channel 101 through the mounting slot of the electronic component. The exhaust channel 201 is used to guide the gas and dust inside the mounting slot to be discharged outward, thereby forming a stable exhaust path. When the nozzle is inserted into the mounting slot of the electronic component, the airflow ejected from the intake channel 101 first enters the interior of the mounting slot and flows along the length of the mounting slot. While carrying dust particles off the surface of the mounting slot, it further flows towards the inlet of the exhaust channel 201 and finally exits the nozzle through the exhaust channel 201, thus forming a complete airflow circulation path.

[0034] One end of the outer sleeve 200 matches the slot outline of the electronic component, and an exhaust groove 2011 is provided at one end of the outer sleeve 200, through which the inner core component 100 passes. Matching the slot outline means that the outer outline of the corresponding insertion end of the outer sleeve 200 is adapted to the opening shape of the electronic component mounting slot. For example, when the mounting slot opening is rectangular, the outer sleeve 200 can be set to a rectangular outline; when the mounting slot opening is rectangular, elliptical, or other irregularly shaped, the outer sleeve 200 can also be set to a corresponding outline structure. Through the shape matching design, a better fit can be achieved between the nozzle and the mounting slot inlet, thereby reducing airflow leakage from the mounting slot inlet and improving the airflow utilization rate inside the mounting slot. Furthermore, an exhaust groove 2011 is provided at the end of the outer sleeve 200 near the mounting slot, through which the inner core component 100 passes. The exhaust groove 2011 not only provides mounting space for the inner core component 100 but also forms an exhaust area as part of the exhaust channel 201. When the inner core 100 passes through the exhaust groove 2011 and extends into the mounting groove, the intake channel 101 can directly deliver the airflow to the deep area of ​​the mounting groove, while the airflow inside the mounting groove can enter the exhaust channel 201 through the exhaust groove 2011 and be discharged outward, thereby forming a directional flow path from the intake channel 101 to the exhaust channel 201 inside the mounting groove.

[0035] In summary, this embodiment forms an air intake path through the inner core component 100 and an exhaust path through the outer casing 200, enabling the mounting slot to simultaneously perform both air intake and exhaust functions. This effectively reduces the formation of disordered turbulence within the confined mounting slot, preventing dust from being blown up and remaining inside the slot for extended periods or redepositing on its surface. Simultaneously, a continuous airflow field is created in the deeper areas of the mounting slot, thereby improving the cleaning effect on the bottom, sidewalls, and internal precision structural surfaces of the slot, achieving highly efficient cleaning of the electronic component mounting slot.

[0036] In a preferred embodiment of this invention, the intake channel 101 extends along the insertion direction, and one end of the outer sleeve 200 is perpendicular to the insertion direction, forming a first end face 202. An exhaust groove 2011 is formed on the first end face 202 and extends along the insertion direction. It is understood that by arranging the intake channel 101 along the insertion direction, compressed gas can be transported along the length of the mounting groove into the interior of the mounting groove, thereby improving the airflow's coverage of the deeper areas of the mounting groove.

[0037] Meanwhile, one end of the inner core 100 protrudes from the exhaust groove 2011 along the insertion direction and is separated from the first end face 202 by a first gap D1. In other words, the outlet end of the inner core 100 extends further into the mounting groove relative to the outer sleeve 200, allowing the outlet of the air intake channel 101 to be closer to the deeper area of ​​the mounting groove. As a result, the compressed airflow can be directly injected into a deeper part of the mounting groove, rather than diffusing prematurely at the entrance of the mounting groove, thereby enhancing the airflow's ability to blow away dust deep within the mounting groove. At the same time, the first gap creates an axial misalignment structure between the outlet of the air intake channel 101 and the exhaust groove 2011. When the airflow is ejected from the air intake channel 101, it first enters the mounting groove and diffuses to the surrounding area, carrying dust particles away from the surface of the mounting groove, and then flows further to the exhaust groove 2011 located in the outer area, and is discharged through the exhaust groove 201. This creates a directional flow path from the air intake channel 101 to the exhaust groove 2011 inside the mounting groove, preventing the intake airflow from directly entering the exhaust groove 201 and causing a short circuit. Furthermore, since the inner core 100 protrudes from the first end face 202, the air intake area and the exhaust area can be effectively separated in space, creating a relatively stable pressure gradient inside the mounting slot. The airflow continuously flows through the mounting slot under the pressure difference, which helps reduce disordered turbulence in local areas, improves the efficiency of dust particle carrying and removal, and reduces secondary dust deposition inside the mounting slot, thereby further improving the cleaning quality of the electronic component mounting slot.

[0038] As another optional implementation of this embodiment, the air intake channel 101 can be inclined relative to the insertion direction, so that the exhaust groove 2011 is opened on the side of the outer sleeve 200, and the air intake channel 101 is arranged corresponding to the groove side wall of the mounting groove.

[0039] Based on the above preferred embodiment, the inner core 100 includes an inner core body 110 and an inner core outlet 120 arranged sequentially along the insertion direction. The end face of the inner core outlet 120 that is perpendicular to the insertion direction is a second end face 121. The second end face 121 and the first end face 202 are separated by a first distance D1. The inner core outlet 120 is narrowed relative to the inner core body 110.

[0040] It is understandable that by setting the inner core outlet 120 to a narrowed structure, the outer contour of the inner core outlet 120 is reduced relative to the inner core body 110, thus creating a larger circumferential space between the inner core outlet 120 and the exhaust groove 2011. This space provides a flow area for airflow inside the mounting groove to enter the exhaust groove 2011, allowing the airflow carrying dust particles to flow more smoothly to the exhaust channel 201 and reducing exhaust resistance. This not only helps to improve exhaust efficiency but also further enhances the directional airflow circulation effect from the air inlet to the air outlet inside the mounting groove. In addition, the inner core outlet 120 protrudes from the first end face 202 and is narrowed, creating a more obvious spatial separation between the air inlet area and the exhaust area. After the airflow is ejected from the second end face 121, it needs to flow through the internal area of ​​the mounting groove before entering the exhaust groove 2011, thereby reducing the possibility of the airflow directly entering the exhaust channel 201 and forming a short-circuit flow. This allows the airflow to fully act on the area to be cleaned, improving the carrying and discharge capacity of dust particles inside the mounting groove and reducing secondary dust deposition.

[0041] More specifically, the second end face 121 includes two long sides 1211 and two short sides 1212 that are connected alternately. The end face of the inner core outlet 120 connected to the long side 1211 is the third end face 122, and the end face of the inner core outlet 120 connected to the short side 1212 is the fourth end face 123. The third end face 122 is inclined, and the fourth end face 123 is parallel to the insertion direction. The fourth end face 123 is connected to the inner core body 110 through the fifth end face 124, which is inclined.

[0042] In this embodiment, when the airflow flows from the inner core body 110 to the inner core outlet 120, it is simultaneously constrained by the third end face 122 and the fourth end face 123 within the same outlet section. The inclined arrangement of the third end face 122 allows the inner core outlet 120 to gradually narrow in the direction corresponding to the long side 1211, thereby gradually compressing and accelerating the airflow in the width direction. The fourth end face 123 is arranged parallel to the insertion direction, which can maintain a relatively stable flow channel boundary in the direction corresponding to the short side 1212, preventing the airflow from contracting rapidly in the short side direction. Thus, the airflow can form a composite guiding state of "narrowing in the long side direction and straight constraint in the short side direction" within the inner core outlet 120. Through the above structure, the inner core outlet 120 does not drastically narrow in both directions at the same time, but preferentially constricts the airflow in the direction corresponding to the long side 1211, while maintaining the flow stability in the direction corresponding to the short side 1212 through the fourth end face 123. This reduces the pressure loss caused by abrupt changes in the cross-sectional area of ​​the flow channel, reduces the possibility of flow separation or local turbulence near the outlet, and allows the airflow to maintain good directionality and stability while being compressed and accelerated.

[0043] In summary, the inner core outlet 120 in this embodiment forms a bidirectional narrowing structure: the long side 1211 narrows at an angle near the second end face 121 via the third end face 122, while the short side 1212 narrows relative to the inner core body 110 via the fifth end face 124, and forms a stable, straight guide via the fourth end face 123. Thus, before entering the second end face 121, the airflow gains both increased jet velocity due to the narrowing structure and directional stability due to the straight guide structure. This increases the airflow jet velocity while reducing airflow turbulence, improving the cleaning stability and dust-carrying capacity of the airflow after it enters the depths of the mounting groove.

[0044] As a preferred embodiment in this example, such as Figures 5 to 8 As shown, the inner core 100 includes an inner core inlet 130 and an inner core body 110 arranged sequentially along the insertion direction; the other end of the outer sleeve 200 is provided with an inlet positioning groove 203 corresponding to the position of the inner core inlet 130. Preferably, the groove structure of the inlet positioning groove 203 can be adapted to the outer contour of the inner core inlet 130 to improve the assembly stability between the inner core 100 and the outer sleeve 200. This embodiment does not specifically limit this.

[0045] The inlet positioning groove 203 and the exhaust groove 2011 are connected at the connecting port 2012 to form an exhaust channel 201; the inner core inlet portion 130 is inserted into the inlet positioning groove 203; the connecting port 2012 is a transition area connecting the inlet positioning groove 203 and the exhaust groove 2011, so that the inlet positioning groove 203 and the exhaust groove 2011 are connected. Thus, the exhaust groove 2011, the connecting port 2012, and the inlet positioning groove 203 together form the main structure of the exhaust channel 201.

[0046] During assembly, the inner core inlet 130 is inserted into the inlet positioning groove 203, while the inner core body 110 passes through the connecting port 2012 and extends into the exhaust groove 2011. Since the inner core body 110 extends through the exhaust channel 201, the exhaust channel 201 forms a surrounding flow channel structure around the inner core 100. When the airflow inside the electronic component mounting slot enters the exhaust groove 2011, it flows along the periphery of the inner core body 110, enters the inlet positioning groove 203 through the connecting port 2012, and finally exits outside the nozzle, thus forming a continuous exhaust path.

[0047] It is worth noting that the inner core body 110 passes through the connecting port 2012 and extends into the exhaust groove 2011, and along the insertion direction, the projection of the connecting port 2012 is not completely covered by the inner core inlet portion 130. That is, when viewed along the insertion direction, the projection of the connecting port 2012 is not completely covered by the inner core inlet portion 130. In other words, at least a partial communication area is maintained between the inner core inlet portion 130 and the connecting port 2012, so that the connecting port 2012 always remains in communication with the inlet positioning groove 203. Therefore, even if the inner core inlet portion 130 is inserted into the inlet positioning groove 203, it will not completely block the exhaust passage 201.

[0048] With the above structural design, the airflow in the exhaust groove 2011 can flow smoothly through the connecting port 2012 and enter the inlet positioning groove 203 without causing airflow blockage or local accumulation at the connecting port 2012. This ensures that the exhaust channel 201 remains unobstructed while guaranteeing the stable installation of the inner core component 100, thus creating a stable and efficient exhaust flow path inside the electronic component mounting slot.

[0049] More specifically, the inner core inlet 130 includes a first inlet 131 and a second inlet 132 arranged sequentially along the insertion direction, and the second inlet 132 abuts against the bottom wall of the inlet positioning groove 203. Along the insertion direction, the projection of the first inlet 131 that is not covered by the second inlet 132 is at least partially aligned with the connecting port 2012, so that an exhaust gap 2013 is formed between the first inlet 131 and the bottom wall of the inlet positioning groove 203. The groove wall of the inlet positioning groove 203 is also provided with an outlet groove 2014. The exhaust groove 2011, the connecting port 2012, the exhaust gap 2013 and the outlet groove 2014 are connected in sequence to form an exhaust channel 201.

[0050] In actual operation, when the airflow carrying dust from inside the electronic component mounting slot enters the exhaust slot 2011, the airflow first flows through the connecting port 2012, then enters the exhaust gap 2013, and finally exits the nozzle through the outlet slot 2014. This forms a continuous exhaust path from the exhaust slot 2011 to the outlet slot 2014, allowing the exhaust channel 201 to run through the entire nozzle structure.

[0051] Compared to directly blocking the inlet positioning groove 203 with an integral inlet structure, this embodiment uses a cooperative design of the first inlet portion 131 and the second inlet portion 132, where the second inlet portion 132 undertakes the positioning function, while the first inlet portion 131 undertakes the flow guiding function. This avoids the problem of the positioning structure occupying the entire flow space and causing the exhaust channel to be blocked, thus achieving a balance between the positioning function and the exhaust function.

[0052] Meanwhile, since the exhaust airflow can gradually flow towards the outlet slot 2014 through the exhaust gap 2013, the pressure change during the airflow process is more gradual, which helps to reduce the formation of airflow backflow, eddies, or pressure accumulation in local areas. The airflow in the exhaust slot 2011 can continuously flow towards the outlet slot 2014, thereby improving the exhaust capacity of the exhaust channel 201.

[0053] Therefore, by setting the first inlet 131, the second inlet 132, the exhaust gap 2013, and the outlet groove 2014, not only can the installation stability between the inner core 100 and the outer kit 200 be improved, but the exhaust channel 201 can also be kept unobstructed, so that a stable and efficient airflow circulation path is formed inside the nozzle, thereby further improving the cleaning efficiency of the electronic component mounting slot.

[0054] More specifically, the first inlet 131 includes a positioning surface 1311 and a guide slope 1312 arranged sequentially along the insertion direction. The positioning surface 1311 is parallel and fits against the bottom wall of the inlet positioning groove 203, and the guide slope 1312 extends obliquely from the positioning surface 1311 to the second inlet 132 in the insertion direction.

[0055] During assembly, when the inner core inlet 130 is inserted into the inlet positioning groove 203, the guide ramp 1312 first contacts the inlet positioning groove 203 and guides the inner core 100 gradually into the predetermined installation position using the inclined structure. The guide ramp 1312 can reduce the possibility of interference, jamming or collision during assembly, thereby improving assembly smoothness and efficiency.

[0056] Simultaneously, the guide slope 1312 also participates in the formation of the exhaust gap 2013. Because a gradually changing flow space is formed between the guide slope 1312 and the bottom wall of the inlet positioning groove 203, the airflow from the connecting port 2012 to the exhaust gap 2013 will not experience significant local pressure loss due to a sudden change in the flow channel cross-sectional area. The exhaust airflow can gradually diffuse along the corresponding area of ​​the guide slope 1312 and flow towards the outlet groove 2014, thereby improving the smoothness of the exhaust process.

[0057] For example, when the airflow carrying dust particles enters the connecting port 2012 from the exhaust channel 2011, the airflow can enter the exhaust gap 2013 through the gradually changing flow channel formed by the guide slope 1312. Since the cross-sectional area of ​​the flow channel changes gradually, the airflow direction can be gradually adjusted, thereby reducing the possibility of local eddies, backflow, and airflow separation, and improving the flow capacity of the exhaust channel 201.

[0058] Furthermore, the positioning surface 1311 forms a relatively straight flow channel boundary, while the guide slope 1312 forms a gradually narrowing or expanding transition boundary. Together, they constitute the flow guiding structure of the exhaust gap 2013. Thus, the exhaust gap 2013 can not only maintain a stable flow space, but also guide and rectify the airflow, allowing the exhaust airflow to flow more smoothly to the outlet slot 2014.

[0059] Therefore, by setting the positioning surface 1311 and the guide slope 1312, on the one hand, the assembly positioning accuracy and assembly stability between the inner core 100 and the outer kit 200 can be improved; on the other hand, the airflow state at the exhaust gap 2013 can be optimized, the exhaust resistance can be reduced, and the guiding capacity of the exhaust channel 201 can be improved, thereby further enhancing the airflow circulation effect and cleaning effect inside the electronic component mounting slot.

[0060] Furthermore, such as Figures 9 to 12 As shown, in order to improve the stability of the inner core 100, a first positioning component 300 is also installed on the outer sleeve 200. The first positioning component 300 includes two first positioning members 310 respectively disposed on both sides of the inner core 100. The first positioning members 310 extend along a first direction perpendicular to the insertion direction.

[0061] The first direction can be understood as the lateral adjustment direction of the inner core 100, which is used to adjust the positional relationship between the inner core 100 and the outer sleeve 200.

[0062] In this embodiment, the outer sleeve 200 has a threaded hole 204 at the position corresponding to the first positioning member 310, and the outer wall of the first positioning member 310 is threaded, and the first positioning member 310 is threadedly connected to the threaded hole 204; the first positioning member 310 is preferably a tightening structure that can move along the first direction. For example, the first positioning member 310 can be a tightening screw, an adjusting screw, a set screw structure, or other positioning structures that can generate a pressing effect along the first direction, and this embodiment does not specifically limit it.

[0063] During assembly, the inner core 100 is first installed inside the outer kit 200. Then, by adjusting the first positioning members 310 located on both sides, the two first positioning members 310 apply opposing clamping forces to the inner core 100. This allows the inner core 100 to be stably clamped between the two first positioning members 310, thereby restricting the free movement of the inner core 100 in the first direction and improving the connection stability between the inner core 100 and the outer kit 200. Furthermore, since the two first positioning members 310 can be adjusted independently, they can not only achieve clamping and fixation but also allow for fine-tuning of the inner core 100's position in the first direction. For example, when one first positioning member 310 is pushed inward and the other first positioning member 310 is appropriately withdrawn, the inner core 100 can generate a slight displacement along the first direction; conversely, it can move in the opposite direction. By adjusting the clamping amount of the two first positioning members 310, the position of the inner core 100 inside the outer kit 200 can be calibrated.

[0064] With the above structural design, the position of the inner core 100 is no longer entirely dependent on the machining dimensions for fixation, but can be compensated and adjusted during the assembly stage. This can correct dimensional deviations caused by part machining errors, assembly errors, or long-term use, thereby improving overall assembly accuracy.

[0065] Furthermore, since the intake channel 101 is formed inside the inner core 100, while the exhaust groove 2011 and the exhaust channel 201 are formed on the outer casing 200, the relative position between the inner core 100 and the outer casing 200 directly affects the fit between the intake structure and the exhaust structure. By fine-tuning the inner core 100 using the first positioning component 300, the positional relationship between the exhaust outlet of the intake channel 101 and the exhaust groove 2011 can be made to a predetermined state, thereby optimizing the airflow field inside the mounting groove and improving the airflow circulation effect.

[0066] Meanwhile, the internal dimensions of different types of electronic component mounting slots may vary. By adjusting the first positioning component 310, the position of the inner core component 100 can be adaptively adjusted according to actual usage requirements, resulting in better airflow matching of the nozzle and thus improving the nozzle's applicability to electronic component mounting slots of different specifications.

[0067] It can be seen that by setting two first positioning members 310 extending along the first direction, the first positioning assembly 300 forms a double-sided clamping and adjusting structure, which can not only improve the connection stability between the inner core 100 and the outer kit 200, but also enable precise fine-tuning of the inner core 100 in the first direction, thereby improving the overall assembly accuracy of the nozzle, the airflow organization effect, and the adaptability of different electronic component mounting slots.

[0068] Furthermore, a positioning mounting groove 312 is provided at one end of the first positioning member 310 away from the inner core body 110, and a second positioning component 400 is provided in the positioning mounting groove 312; the second positioning component 400 includes a second positioning member 410 threadedly connected to the positioning mounting groove 312, and a clamping member 420 is installed on the second positioning member 410, and the clamping member 420 is offset from the axis of the second positioning member 410.

[0069] It should be further explained that the two second positioning members 410 are located on both sides of the inner core body 110 along the second direction, such as... Figure 10 As shown, the second direction is perpendicular to the first direction. One second positioning member 410 is located on the lower left side of the inner core body 110, and the other second positioning member 410 is located on the upper right side of the inner core body 110. Furthermore, the second positioning member 410 is a disc-shaped component with an outline that matches the positioning mounting groove 312, and is equipped with an external thread structure, allowing it to rotate and advance within the positioning mounting groove 312. The clamping member 420 is offset from the axis of the second positioning member 410, and the axis of the second positioning member 410 coincides with the mid-surface of the inner core body 110. Therefore, when the second positioning member 410 rotates, the distance between the clamping member 420 and the mid-surface of the inner core body 110 can be changed, thus adjusting the distance in the second direction.

[0070] Understandably, by integrating the second positioning component 400 inside the first positioning component 310, further positioning and locking functions can be achieved without increasing external installation space, thereby improving the integration and compactness of the overall structure.

[0071] For example, when the second positioning member 410 rotates to different angular positions, the position of the clamping member 420 relative to the mid-surface also changes, thereby altering the position of the clamping member 420 on the inner core body 110. This enables minute positional adjustment of the inner core body 110 in the second direction. Simultaneously, since the two second positioning members 410 are located diagonally on opposite sides of the inner core body 110, they can cooperate with the first positioning member 310 to form a two-dimensional adjustment mechanism. The first positioning member 310 is used to adjust the position of the inner core body 110 in the first direction, while the second positioning member 400 is used to adjust the position of the inner core body 110 in the second direction. Through their coordinated operation, precise positioning of the inner core body 110 in two mutually perpendicular directions can be achieved, thereby improving the assembly accuracy between the intake channel 101 and the exhaust channel 201.

[0072] It is important to emphasize that since the second positioning component 400 is mostly housed inside the positioning mounting slot 312, there is no need to set up an additional adjustment mechanism around the exhaust channel 201. This effectively reduces the occupation of exhaust space, allowing the exhaust channel 201 to maintain a large flow cross-sectional area. This helps to reduce exhaust resistance, avoid the formation of flow bottlenecks in the exhaust channel 201, and improve exhaust efficiency. Simultaneously, the two second positioning components 410 are arranged diagonally around the inner core body 110, allowing the adjustment mechanism to be distributed in the outer area of ​​the exhaust channel 201 without concentrating in the same flow channel space. This ensures the realization of the adjustment function while reducing the interference of the positioning mechanism on the airflow path, thus helping to maintain a uniform airflow state within the exhaust channel 201.

[0073] Therefore, by setting a disc-shaped second positioning component 410, an eccentrically positioned clamping component 420, and an integrated mounting structure in the positioning mounting groove 312, the second positioning component 400 forms an eccentric adjustment mechanism. This not only enables precise fine-tuning of the inner core body 110 in the second direction, but also reduces the occupation of the exhaust channel 201 while ensuring structural compactness, thereby facilitating stable airflow inside the nozzle and improving overall cleaning performance.

[0074] More specifically, the inner core body 110 of the inner core component 100 includes a sixth end face 111 perpendicular to the first direction, and the first positioning component 310 includes a positioning plane 311, which at least partially abuts against the sixth end face 111. The sixth end face 111 is arc-shaped and includes an end face edge region 1111 that abuts against the connected end face and an arc-shaped region 1112 located between the two end face edge regions 1111; the clamping component 420 abuts against the end face edge region 1111, and the first positioning component 310 abuts against the arc-shaped region 1112.

[0075] During specific assembly, the positioning plane 311 of the first positioning member 310 abuts against the arc surface area 1112, and the clamping member 420 in the second positioning assembly 400 abuts against the end face edge area 1111. In other words, the first positioning member 310 and the clamping member 420 act on different areas of the sixth end face 111, so that the adjustment function and the locking function are set independently.

[0076] When the position of the inner core body 110 needs to be adjusted in the first direction, the first positioning member 310 acts on the arc surface area 1112 through the positioning plane 311. The arc surface area 1112 can reduce the jamming phenomenon caused by local interference during the adjustment process. When the first positioning member 310 pushes the inner core body 110 to move, it is not easy for stress concentration to form due to the contact edge, which helps to improve the smoothness of the adjustment process and the repeatability of positioning accuracy. The clamping member 420 abuts against the end face edge area 1111. Since the end face edge area 1111 is located outside the arc surface area 1112, the action areas of the clamping member 420 and the first positioning member 310 are separated from each other. Therefore, when the position is adjusted using the first positioning member 310, the clamping member 420 does not directly act on the arc surface area 1112, thereby reducing the influence of the locking mechanism on the adjustment process; and after the position adjustment is completed, the clamping member 420 can apply a locking force to the inner core body 110 through the end face edge area 1111, thereby maintaining the adjusted positioning state.

[0077] By setting the functional area of ​​the positioning plane 311 in the arc surface area 1112 and the functional area of ​​the clamping member 420 in the end face edge area 1111, the adjustment mechanism and the locking mechanism form a partitioned force structure. On the one hand, this ensures that the first positioning member 310 can make precise fine adjustments to the inner core body 110; on the other hand, it ensures that the clamping member 420 provides a stable and reliable locking effect, thereby avoiding mutual interference between the adjustment and locking processes. Therefore, by setting the sixth end face 111 as an arc surface structure including the end face edge area 1111 and the arc surface area 1112, and making the first positioning member 310 act on the arc surface area 1112 and the clamping member 420 act on the end face edge area 1111, not only can the position adjustment accuracy and locking stability of the inner core body 110 be improved, but the adjustment function and the locking function can also be separated, improving the overall structural compactness and facilitating the stable flow of air inside the nozzle.

[0078] In this embodiment, the assembly process of the nozzle for electronic components is as follows: First, the inner core 100 is inserted into one end of the outer sleeve 200, so that the inner core body 110 passes through the connecting port 2012 and extends into the venting groove 2011, while the inner core inlet 130 is inserted into the inlet positioning groove 203. During insertion, the guide slope 1312 on the first inlet 131 guides the inner core inlet 130 to gradually enter the inlet positioning groove 203, reducing the possibility of assembly interference. When the second inlet 132 abuts against the bottom wall of the inlet positioning groove 203, the initial positioning of the inner core 100 in the insertion direction is completed.

[0079] Subsequently, by adjusting the first positioning members 310 located on both sides of the outer casing 200, the first positioning members 310 are moved towards the inner core body 110 in the first direction, and the positioning plane 311 abuts against the arc area 1112 of the sixth end face 111. By adjusting the pushing amount of the first positioning members 310 on both sides respectively, the position of the inner core 100 in the first direction can be adjusted, so that the air intake channel 101 and the exhaust groove 2011 reach the predetermined mating position. After completing the position adjustment in the first direction, the second positioning member 410 is rotated. Since the second positioning member 410 is threadedly connected to the positioning mounting groove 312, and the clamping member 420 is offset from the axis of the second positioning member 410, the distance between the clamping member 420 and the middle surface of the inner core body 110 changes when the second positioning member 410 rotates, thereby pushing the inner core body 110 to produce a slight displacement in the second direction. By adjusting the two second positioning members 410 respectively, the position calibration of the inner core 100 in the second direction can be achieved. Once the inner core 100 is adjusted to the predetermined position, the clamping member 420 abuts against the edge area 1111 of the end face, thereby completing the locking and fixing.

[0080] After assembly, the intake channel 101, exhaust groove 2011, connecting port 2012, exhaust gap 2013 and outlet groove 2014 form a complete airflow path.

[0081] In use, the electronic component is inserted into its mounting slot using a nozzle, with the end of the outer casing 200 near the slot opening corresponding to the slot opening. Then, the air source is connected to the air inlet channel 101, and compressed gas is delivered to the deep region of the mounting slot via the air inlet channel 101. The airflow exits from the second end face 121 and enters the mounting slot, forming a high-speed directional airflow inside. This high-speed airflow blows away dust particles adhering to the sidewalls, bottom, and surface of the electronic component of the mounting slot, and propels the dust particles in a predetermined direction. Subsequently, the airflow carrying the dust particles enters the exhaust channel 2011 and flows sequentially through the connecting port 2012, exhaust gap 2013, and outlet channel 2014, finally exiting outside the nozzle. This forms a continuous circulating airflow path from the air inlet channel 101 to the exhaust channel 201, creating a stable directional flow field inside the mounting slot, thereby continuously carrying out dust particles from within the mounting slot.

[0082] Therefore, this embodiment can form a stable and efficient airflow circulation path within a limited space, achieving efficient cleaning of the electronic component mounting slots, especially the optical module mounting slots, thereby improving the operational reliability and service life of electronic components.

[0083] Example 2: This embodiment also provides an airflow cleaning device, including an air source and a nozzle for electronic components as described in Embodiment 1. The air source is connected to the air inlet channel 101, and the exhaust channel 201 can be connected to a collection device. The air source can be a compressed air system, an air compressor, a high-pressure gas cylinder, a vacuum generator's supporting air source, or other air supply equipment capable of providing airflow power; this embodiment does not specifically limit its application. The collection device can be a dust collection box, a filter assembly, a dust suction device, a negative pressure collection device, or other devices capable of collecting particulate matter; this embodiment does not specifically limit its application either.

[0084] Therefore, the airflow cleaning equipment provided in this embodiment, through the cooperation of nozzles for electronic components and air source, can form a stable directional airflow path inside the mounting slot of electronic components, and collect the discharged dust through a collection device, thereby improving the cleaning efficiency of electronic components and reducing the secondary diffusion and secondary pollution of dust.

[0085] Example 3: This embodiment also provides a light module cleaning device, including an air source and a nozzle for electronic components as described in Embodiment 1. The air source is connected to the air inlet channel 101, and the exhaust channel 201 can be connected to a collection device. The air source can be a compressed air system, an air compressor, a high-pressure gas cylinder, a vacuum generator's supporting air source, or other air supply equipment capable of providing airflow power; this embodiment does not specifically limit its application. The collection device can be a dust collection box, a filter assembly, a dust suction device, a negative pressure collection device, or other devices capable of collecting particulate matter; this embodiment does not specifically limit its application either.

[0086] Therefore, the optical module cleaning equipment provided in this embodiment can form a stable directional airflow path inside the optical module mounting slot by cooperating with the optical module nozzle and the air source, and collect the discharged dust in a concentrated manner through the collection device, thereby improving the cleaning efficiency of the optical module and reducing the secondary diffusion and secondary pollution of dust.
