Description

Technical Field

[0001] This application relates to the field of air pump lighting design, and further to a lighting structure and air pump. Background Technology

[0002] Existing air pump products typically use screws or adhesive to simply fix the light panel to the housing when installing the lighting components. This method is not only inconvenient to assemble, but also prone to causing the light panel to loosen or shift due to vibration or external impact during air pump operation, resulting in unstable lighting effects and affecting the reliability of circuit connections. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this application is to provide a lighting structure and air pump that can reliably fix the light panel and ensure a stable lighting effect.

[0004] To achieve the above objectives, this application provides a lighting structure disposed on an air pump, comprising:

[0005] A support structure, fixed to the main body structure of the air pump, has a first connecting side and a second connecting side, with the first connecting side facing the air outlet end of the air pump.

[0006] A light panel, wherein a first light strip is provided on the light panel, and the light panel is electrically connected to a main control board so as to control the lighting effect emitted by the light strip through the main control board;

[0007] A first lampshade covers the outside of the first lamp strip. The first lampshade has a connecting portion along its central axis. At least part of the connecting portion is located within the cavity of the first lampshade. The connecting portion is simultaneously connected to the lamp panel and the supporting structure, and the lamp panel is confined between the first connecting side of the supporting structure and the first lampshade.

[0008] In some embodiments, the connecting portion extends from the end of the first lampshade away from its opening toward the lamp plate, the lamp plate having a first through hole, and the end of the connecting portion away from the bottom wall of the first lampshade having a limiting structure.

[0009] In the installed state, the limiting structure passes through the first through hole and forms a direct or indirect cooperation with the support structure to limit the relative displacement between the first lampshade, the lamp panel and the support structure.

[0010] In some embodiments, a second through hole is provided on the main control board, and the support structure includes a support body and multiple support arms. The multiple support arms are respectively fixedly connected to the periphery of the support body and extend unidirectionally along the axis to form a cantilever. The support structure is connected to the main structure of the air pump through the multiple support arms.

[0011] The first connecting side and the second connecting side correspond to two opposite end faces of the support body. In the installed state, the connecting part passes through the first through hole and the second through hole to connect with the support body, and the main control board is fixed to the second connecting side of the support structure.

[0012] In some embodiments, the support body has a hollow hole that extends through itself along the axial direction, and the inner peripheral wall of the hollow hole is provided with a continuous or discontinuous flange, the two end faces of the flange being smooth surfaces to form a ring-like structure located inside the hollow hole.

[0013] The flange facing the first lampshade is configured as the first connecting side, and the flange facing away from the first lampshade is configured as the second connecting side. The lamp board abuts against the first connecting side, and the main control board abuts against the second connecting side. Thus, the lamp board and the main control board are simultaneously fixed to both sides of the support body through the connecting part.

[0014] In some embodiments, the limiting structure includes at least two symmetrically distributed hooks, the hooks being oriented away from the central axis of the first lampshade, the hooks having a preset interval, and in the natural state, the radial distance from the outermost end of each hook to the central axis of the first lampshade corresponds to the radius of the first base circle, the diameter of the first base circle being at least greater than the diameter of the second via on the main control board.

[0015] During installation, the preset interval between the hooks is compressed, allowing the limiting structure to pass through the second through hole. After passing through the second through hole, the hooks naturally rebound and form an abutment limit on the end face of the main control board. The first lampshade simultaneously abuts against the lamp plate, so that the main control board, the lamp plate, and the first lampshade are sequentially stacked and connected to the support structure.

[0016] In some embodiments, each of the support arms is provided with an anti-detachment buckle on its side near the support body, the anti-detachment buckle extending towards the central axis of the support structure, and the end face of the main control board facing away from the first lampshade abutting against the anti-detachment buckle in the installed state to limit the axial and radial displacement of the main control board;

[0017] And / or, the support arms are all elastic to deform in order to accommodate the installation of the main control board.

[0018] In some embodiments, the light panel is further provided with a second light strip, which is arranged around the outer periphery of the first light strip; wherein, the first light strip includes at least one ambient light strip, the second light strip includes at least one illumination light strip, and a first lampshade covers the outermost periphery of the first light strip and forms a partition between the first light strip and the second light strip.

[0019] In some embodiments, the lighting structure further includes a second lampshade that covers the outermost periphery of the second light strip and is fixedly connected to the main structure of the air pump; and / or, the first lampshade is made of a matte material.

[0020] In some embodiments, the end face profile of the second lampshade is configured as a recessed profile that tapers inward thereto, the recessed profile protruding in the direction from the second lampshade toward the first lampshade, and in the installed state, the end faces of the first lampshade and the second lampshade do not contact each other.

[0021] Another aspect of this application also provides an air pump, comprising:

[0022] The lighting structure in any of the above embodiments;

[0023] impeller;

[0024] Drive motor;

[0025] The motor bracket serves as the main structure of the air pump. The impeller and the drive motor are respectively located on opposite sides of the electrode bracket. The output shaft of the drive motor passes through the motor bracket and is connected to the impeller to drive the impeller to rotate. The support structure of the lighting structure is fixed to the electrode bracket.

[0026] Compared with the prior art, this application has at least the following beneficial effects:

[0027] By forming a connecting part in the first lampshade and connecting it to the lamp panel and supporting structure, the lamp panel can be positioned and fixed without relying on traditional screws or adhesives, ensuring the stability of the electrical connection and reducing adverse situations caused by lamp panel shaking during use. At the same time, it reduces the number of fasteners required for the fixed installation of the lighting structure, which can speed up assembly efficiency and help increase production.

[0045] Lighting functionality is increasingly being incorporated into existing air pump products for ambient cues or localized lighting. However, most current lighting components are attached to the air pump housing using screws or adhesives. This installation method is not only cumbersome but also susceptible to vibrations, heat, or external impacts generated during air pump operation, potentially leading to loosening or misalignment between the light panel and its corresponding mounting components.

[0046] When the position of the light panel 2 is unstable, it will first cause fluctuations in the lighting effect, such as the position of the light spot shifting or the lighting angle being inconsistent, affecting the user's intuitive experience. Moreover, the loosening of the light components may even cause electrical connection and equipment malfunctions.

[0047] In one embodiment, refer to the appendix to the specification. Figures 1 to 4 The present application provides a lighting structure disposed on an air pump, comprising a support structure 1, a lamp plate 2, and a first lampshade 31. The support structure 1 is fixed to the main body structure 8 of the air pump, and has a first connecting side 101 and a second connecting side 102 facing each other, wherein the first connecting side 101 faces the air outlet end of the air pump. A first lamp strip 21 is disposed on the lamp plate 2, and the lamp plate 2 is electrically connected to a main control board 5 so as to control the lighting effect emitted by the first lamp strip 21 through the main control board 5.

[0048] The first lamp cover 31 covers the outside of the first lamp strip 21. The first lamp cover 31 has a connecting part 311 along its central axis. At least part of the connecting part 311 is located in the cavity of the first lamp cover 31. The connecting part 311 is simultaneously connected to the lamp plate 2 and the support structure 1, and the lamp plate 2 is confined between the first connecting side 101 of the support structure 1 and the first lamp cover 31.

[0049] This structural design allows the lamp panel 2 to be stably positioned within the limited space inside the air pump, preventing displacement due to vibration or external forces during air pump operation. This ensures the stability and uniformity of the lighting effect, while simplifying the assembly process and improving overall reliability.

[0050] Specifically, by forming a connecting part 311 in the first lampshade 31 and connecting it to the lamp plate 2 and the support structure 1, the lamp plate 2 can be positioned and fixed without relying on traditional screws or adhesives, avoiding failure problems caused by loose connectors or aging adhesives. At the same time, the lamp plate 2 is clamped and positioned between the support structure 1 and the first lampshade 31, ensuring stable electrical connection and reducing poor contact caused by the lamp plate 2 shaking during use.

[0051] In a specific embodiment, the connecting part 311 is designed as several inserts, which can be inserted into the pre-set mounting holes on the support structure 1. Reliable fixing is achieved through interference fit or snap-fit ​​structure, ensuring the stability of the lamp panel 2 and making the assembly process more convenient, suitable for mass production. The support structure 1 can be provided with a support plate with several mounting holes, allowing the inserts to pass through the mounting holes on the support plate. Simultaneously, multi-point installation and fixing can be achieved, increasing the stability of the structure.

[0052] Furthermore, optionally, the support structure 1 is fixed to the main structure 8 of the air pump by screwing or snapping, so as to facilitate disassembly and maintenance later.

[0053] Based on the above embodiments, in one embodiment, the connecting part 311 extends from the side of the first lampshade 31 away from its opening toward the lamp plate 2, and a first through hole 20 is provided at a corresponding position on the lamp plate 2. A limiting structure 40 is provided at the end of the connecting part 311 away from the bottom wall of the first lampshade 31. During the assembly process, the limiting structure 40 can pass through the first through hole 20 on the lamp plate 2 and form a matching limiting with the support structure 1, thereby realizing a stable fixed relationship between the lampshade, the lamp plate 2 and the support structure 1.

[0054] In this design, the connecting portion 311 of the first lampshade 31 extends from its bottom wall toward the lamp plate 2. During assembly, the connecting portion 311 passes through the pre-drilled first through hole 20 on the lamp plate 2, thereby initially forming a relative connection between the first lampshade 31 and the lamp plate 2. The first lampshade 31 is then fitted into the lamp plate 2 via the connecting portion 311, thus preventing free movement of the first lampshade 31 in the horizontal direction. Subsequently, the limiting structure 40 of the connecting portion 311 continues to move and forms a direct or indirect mating and limiting relationship with the support structure 1.

[0055] In this way, the first lampshade 31 is not only initially positioned through the through hole of the lamp plate 2, but also reinforced as a whole through the further action of the limiting structure 40 and the supporting structure 1. This step-by-step limiting method from the inside out is convenient for installation and can reduce the number of additional fasteners, thereby obtaining a more compact and reasonable overall structural layout.

[0056] In this embodiment, the so-called direct fit can be understood as the limiting structure 40 itself forming contact with the supporting structure 1 and achieving fixation. For example, the limiting structure 40 is a protrusion, a buckle or other similar connector, which can be directly inserted into the hole or slot of the supporting structure 1 after passing through the lamp plate 2, thereby achieving stable limiting.

[0057] Indirect connection involves establishing a link with the supporting structure 1 through intermediate or transitional components. For example, the limiting structure 40 can extend and engage with a mounting plate or gasket, and these intermediate components are then securely fastened to the supporting structure 1 to achieve final limiting. Through diverse designs, the solution can be reliably applied in various installation environments. For instance, direct connection can be used for rapid fixing when structural space is limited, while in scenarios requiring vibration reduction, heat insulation, or insulation, indirect connection can be used to add transitional components to achieve composite functions.

[0058] The first through hole 20 on the lamp panel 2 can be designed to match the shape of the limiting structure 40, such as being round, square or other irregularly shaped holes, to ensure that the limiting structure 40 can pass through smoothly and maintain a stable position.

[0059] In one embodiment, please refer to the appendix to the specification. Figure 2 , Figure 3 , Figure 9 as well as Figure 10 The main control board 5 has a second through hole 50. The support structure 1 includes a support body 11 and multiple support arms 12. The support arms 12 are fixedly connected to the periphery of the support body 11 and extend unidirectionally along the axial direction to form a cantilever structure. The support body 11 is stably connected to the main body structure 8 of the air pump through the support arms 12, thereby providing a stable installation base for the lighting structure. The support body 11 has two opposite end faces, one end face serving as the first connection side 101 and the other end face serving as the second connection side 102.

[0060] In the assembled state, the limiting structure 40 on the connecting part 311 passes through the first through hole 20 on the lamp panel 2 and the second through hole 50 on the main control board 5 in sequence, and finally forms a fixed connection with the support body 11. Through this through-type limiting design, the first lampshade 31, the lamp panel 2 and the main control board 5 can be stacked on each other and jointly fixed to the support body 11, thereby achieving unified positioning and reinforcement of multi-layer components in the axial direction. At the same time, the main control board 5 is fixed to the second connecting side 102 of the support structure 1, thereby ensuring the stable installation of electrical components.

[0061] In this embodiment, the limiting structure 40 of the connecting part 311 simultaneously penetrates the lamp plate 2 and the main control board 5, and cooperates with the supporting body 11, avoiding the practice of setting independent fasteners for each layer of components, greatly reducing the number of parts and assembly steps, and improving the overall assembly efficiency.

[0062] Furthermore, the support arm 12 is arranged in a cantilever configuration, which creates a stable support relationship between the support body 11 and the air pump body, while leaving space in the middle to accommodate the lamp panel 2, the main control board 5, and related electrical components, thus achieving a balance between compact structure and functional integration. More importantly, the multi-layered stacked components are fixed on the same axis by the same limiting member, which can effectively suppress the relative displacement between components and improve seismic resistance and durability.

[0063] In a specific embodiment, the support body 11 can be configured as a frame structure, and the support arms 12 extend outward from the periphery in an equally angularly distributed manner and are fixed to the air pump body, thereby balancing structural strength and stress distribution. In another embodiment, the support body 11 can be a polygonal structure, with the support arms 12 arranged at intervals along the polygonal edges to facilitate adaptation to air pump bodies of different shapes.

[0064] In one embodiment, based on the above, the support body 11 has a hollow hole 110 extending through it along its axial direction, and the inner peripheral wall of the hollow hole 110 has a continuous or discontinuous flange 112. The flange 112 is structurally a ring-shaped member, with both end faces being smooth surfaces, which can provide opposing abutment reference surfaces in the axial direction.

[0065] The end face of flange 112 facing the first lampshade 31 serves as the first connecting side 101, and the end face of flange 112 facing away from the first lampshade 31 serves as the second connecting side 102. Lamp plate 2 abuts against the first connecting side 101, and main control board 5 abuts against the second connecting side 102. The limiting structure 40 of connecting part 311 passes through lamp plate 2 and main control board 5 and is connected to the supporting body 11. Lamp plate 2 and main control board 5 can be reliably limited at the two end face positions of flange 112, thereby achieving synchronous fixation of the two side components.

[0066] Understandably, in this embodiment, the flange 112 formed within the hollow hole 110 serves as a bidirectional positioning reference, enabling the lamp board 2 and the main control board 5 to directly abut and be positioned without the need for additional shims or independent fixing components. Both sides of the flange 112 are smooth surfaces, ensuring that the lamp board 2 and the main control board 5 can fit tightly together during assembly, while avoiding damage to components caused by sharp structures.

[0067] In this way, the connecting part 311 and the flange 112 work together to form a stable constraint on the multi-layer components, so that the entire light structure forms a highly compact assembly state inside the air pump. This effectively solves the problems of excessive number of parts, complex assembly, and insufficient space utilization caused by the independent fixing of multi-layer components, and helps to improve the reliability and durability of the light structure.

[0068] In specific embodiments, the flange 112 itself can be a one-piece structure, either integrally cast or injection molded, such as a continuous ring structure, or it can adopt a segmented design, forming a ring support through multiple discontinuously distributed segments to reduce interference during assembly and improve heat dissipation performance. The structure can be flexibly adjusted according to the actual internal space conditions and usage requirements of the air pump, thereby further leveraging the advantages of this solution.

[0069] Based on the above embodiments, in one embodiment, such as Figure 5 and Figure 7 As shown, the limiting structure 40 includes at least two symmetrically distributed hooks 401. The multiple hooks 401 are arranged in a ring relative to the central axis of the first lampshade 31, and the orientation of each hook 401 is away from the central axis of the first lampshade 31, thereby forming an outwardly flared structural shape in its natural state.

[0070] For the sake of consistent description, such as Figure 8As shown, the center of the circle is defined as the central axis of the first lampshade 31, and the distance from the outermost end of the hook 401 to the central axis of the first lampshade 31 is (due to the viewing angle). Figure 8 The imaginary circle with radius equal to the distance from the center point of the first lampshade 31 is called the first base circle A. In this embodiment, the diameter of the first base circle A is at least larger than the diameter of the second via 50 on the main control board 5, so as to ensure that the hook 401 cannot pass directly through the second via 50 under normal conditions.

[0071] During actual installation, the preset intervals between multiple hooks 401 are compressed, forcing the limiting structure 40 to close and pass through the second through hole 50. Once the hooks 401 of the limiting structure 40 have completely passed through the second through hole 50, they rebound naturally to their open state, allowing their outer edges to abut against the end face of the main control board 5, thus achieving the functions of limiting and locking. In this way, the main control board 5 can be securely fixed to the second connecting side 102 of the support structure 1. Simultaneously, the first lampshade 31 abuts against the lamp panel 2 in the installed state, causing the main control board 5, lamp panel 2, and first lampshade 31 to be sequentially stacked and connected on the support structure 1, resulting in a compact and stable overall structure.

[0072] Through the above design, the limiting structure 40 not only serves the purpose of rapid assembly and positioning, but also avoids reliance on traditional fasteners such as screws, reducing the number of parts and improving assembly efficiency. The latch 401 relies on the elastic recovery of the structure itself to complete the locking, and has good repeatable installation and disassembly performance, which can reduce the complexity of maintenance and replacement processes. In addition, the force direction of the latch 401 is perpendicular to the end face of the main control board 5, which can effectively prevent loosening or displacement, further enhancing the limiting effect.

[0073] Furthermore, in practical applications, the number of hooks 401 is not limited to two; it can also be three or more, and can be flexibly selected according to the diameter of the second through hole 50 on the main control board 5, load requirements, and installation space. When multiple hooks 401 are distributed circumferentially at equal intervals or symmetrically, a more balanced force distribution effect can be achieved, thereby further improving the reliability and stability of the limit. At the same time, the end shape of the hooks 401 can be arc-shaped, barbed, or have a structure with a buffer slope to adapt to different assembly requirements.

[0074] In one embodiment, such as Figure 4 , Figure 5 and Figure 10 As shown, each support arm 12 is provided with an anti-detachment buckle 121 on the side near the support body 11. The anti-detachment buckle 121 can be a protruding structure integrally formed on the support arm 12, and its extension direction is towards the central axis of the support structure 1. That is, multiple anti-detachment buckles 121 are distributed in a ring and all point to the center, thereby forming a multi-point limit in the installed state.

[0075] In this embodiment, the end face of the main control board 5 facing away from the first lampshade 31 can abut against the anti-detachment buckle 121, so that the support arm 12 can play a dual role of axial and radial limiting on the main control board 5. It can be understood that after the main control board 5 and the support structure 1 are assembled, one side of the main control board 5 abuts against the flange 112 in the above embodiment, and the other side cooperates with the anti-detachment buckle 121 and the limiting structure 40 for limiting. At the same time, the displacement of the periphery is also limited by multiple support arms 12 to prevent the main control board 5 from eccentric displacement, so that the main control board 5 always maintains an accurate positional relationship with the support structure 1.

[0076] In this way, the main control board 5 forms multi-directional limiting through multiple structures, which can significantly reduce the risk of loosening and displacement caused by external impact, vibration, or long-term use, thereby improving the structural stability and reliability of the overall device. In practical applications, the shape of the anti-disengagement buckle 121 can be designed and optimized as needed. For example, it can be provided with an arc contour or chamfer to reduce the insertion force when installing the main control board 5 and improve the smoothness of assembly.

[0077] Furthermore, in one embodiment, all support arms 12 are elastic. For details, please refer to the appendix to the specification. Figure 4 A connecting structure 122 is provided on the support arm 12 for connecting with the main structure 8 of the air pump. The connecting structure 122 extends into the interior of the support structure 1. During installation, the support arm 12 is elastic, so the operator can appropriately bend the support arm 12 to insert the main control board 5 into the position area within the anti-disengagement buckle 121. In this way, the connecting structure 122 will not interfere with the installation of the main control board 5.

[0078] In one embodiment, such as Figure 2 As shown, a second light strip 22 is also provided on the light panel 2. The second light strip 22 is distributed in a ring around the outer periphery of the first light strip 21, thus forming a configuration of two light strips. The first light strip 21 includes at least one ambient light strip, whose luminous intensity and color can be used to create specific atmospheric effects, such as soft background light or decorative light. The second light strip 22 includes at least one main lighting strip, mainly used to provide a stronger main lighting effect to meet the basic brightness requirements in actual use.

[0079] Among them, such as Figure 5As shown, the first lampshade 31 covers the outermost periphery of the first light strip 21 and forms a partition between the first light strip 21 and the second light strip 22, thus clearly separating the spatial arrangement of the two types of light strips. On the one hand, the ambient light strip can achieve a softened light effect through the first lampshade 31, avoiding direct glare, while also creating a warm or personalized lighting atmosphere. On the other hand, the lighting strip is located on the periphery, with a wider illumination range and higher light intensity, providing practical lighting, thus making the air pump both decorative and functional.

[0080] Thus, this clear and distinct light source zoning in this embodiment not only improves light utilization but also provides users with a more intuitive control mode. Users can turn on the ambient light strip and the lighting strip individually or in combination as needed to achieve diverse lighting mode switching.

[0081] In practical implementation, ambient light strips can use RGB or RGBW LED arrays, and different colors and brightness can be achieved by adjusting the electronic control parameters to suit the needs of festivals, leisure, or other atmospheres. Lighting strips, on the other hand, can use high color rendering and high brightness white LEDs to meet the light intensity and uniformity required for reading, working, or daily lighting.

[0082] In one embodiment, based on the design of the above embodiments, such as Figure 3 , Figure 4 As shown, the lighting structure also includes a second lampshade 32, which covers the outermost periphery of the second light strip 22 and is fixedly connected to the main structure 8 of the air pump. By adding an independent cover to the outside of the second light strip 22, the light emitted by the second light strip 22 can be effectively limited and guided, making its light distribution more uniform. It also serves to prevent dust and provide protection, ensuring the long-term stable operation of the lighting source. Accordingly, the second lampshade 32 should preferably be made of transparent or high-transmittance material so that the lighting strip can fully utilize its luminous intensity to achieve its main lighting function without causing significant loss of luminous efficiency.

[0083] Preferably, the first lampshade 31 is made of a matte material, which mainly serves to soften and diffuse the light emitted by the ambient light strip. The scattering effect of the matte surface can significantly reduce the glare problem caused by direct light, making the ambient light present a soft and uniform visual effect, and improving the overall visual experience and comfort.

[0084] Thus, the first lampshade 31 and the second lampshade 32 form a differentiated and complementary relationship in terms of material selection and functional positioning: the former focuses on softening ambient light, while the latter ensures the transmission and efficiency of illumination light. Together, they achieve a balance between light effect zoning and visual experience. In this way, the lighting structure can simultaneously meet the needs of ambient lighting and functional lighting within the same device.

[0085] In some implementations, a light-colored coating or diffusion particles may be added to the inner wall of the first lampshade 31 to further enhance the scattering effect and make the ambient light softer and more natural.

[0086] In one embodiment, append Figure 3 As shown, the end face contour of the second lampshade 32 is designed as a concave contour that tapers inward. The concave contour protrudes along the direction from the second lampshade 32 to the first lampshade 31, thus giving the overall shape of the second lampshade 32 a concave form. In the installed state, a gap is maintained between the end faces of the first lampshade 31 and the second lampshade 32, and they do not make direct contact.

[0087] First, the concave contour design effectively shortens the axial extension of the second lamp cover 32, so that the overall length of the lamp cover is compressed while ensuring its function, thereby making the entire air pump more compact in the axial direction, which is conducive to the development of the air pump towards miniaturization.

[0088] Secondly, the fact that the end faces of the first lampshade 31 and the second lampshade 32 do not touch helps to create a buffer air gap between them. This gap not only avoids heat accumulation caused by heat conduction between the covers, but also facilitates natural airflow convection, thereby improving heat dissipation efficiency and avoiding the risk of aging of the cover material or degradation of light source performance due to local overheating.

[0089] Furthermore, due to the concave structure of the end face, the second lampshade 32 also presents an inwardly tapering transition shape in terms of visual effect. This not only enhances the overall aesthetics of the device but also reduces the abruptness to the external space to a certain extent, making the air pump's shape more harmonious. In some embodiments, the depth and curvature of the concave contour can be optimized according to the relative position of the lamp strip and the cover to take into account both light diffusion and heat dissipation requirements.

[0090] In optional embodiments, the recessed profile of the second lampshade 32 can be designed as an arc surface, a conical surface, or a multi-segmented polygonal profile. For example, an arc-shaped recessed profile provides a softer appearance and facilitates light transition, while a multi-segmented polygonal profile is more conducive to reducing material usage and enhancing mechanical strength. In addition, an anti-fogging or heat-resistant coating can be added to the inner wall of the recessed profile to further improve the stability and reliability of use.

[0091] In one embodiment, the appendix to the specification can be mainly referred to. Figure 1 and Figure 6According to another aspect of this application, this application further provides an air pump, including the lighting structure, impeller 6, drive motor 7, and motor bracket 80 as described in any of the above embodiments. The motor bracket 80 serves as the main structure 8 of the air pump, providing overall installation and load-bearing functions. The impeller 6 and drive motor 7 are respectively arranged on opposite sides of the motor bracket 80. The output shaft of the drive motor 7 passes through the motor bracket 80 and is connected to the impeller 6, so that when the motor is energized, it drives the impeller 6 to rotate, thereby completing the compression and delivery of gas. The support structure 1 of the lighting structure is fixed on the motor bracket 80, thereby tightly integrating the lighting component with the air pump body to achieve structural integration. (The connecting components for connection are not shown in the accompanying drawings; only the connecting holes are shown.)

[0092] Through the connecting part 311 on the first lamp cover 31, the lamp plate 2 and the first lamp cover 31 can be synchronously fixed to the support structure 1, forming a stacked connection relationship. This not only ensures the stability and durability of the lighting components during the operation of the air pump, but also reduces the need for additional fasteners, making the structure simpler and more compact.

[0093] In this embodiment, on the one hand, the lighting structure is organically integrated into the air pump body as an additional functional module, without occupying extra space or affecting the normal arrangement of the impeller 6 and drive motor 7, thus keeping the air pump compact in overall size. On the other hand, the connecting part 311 of the first lamp cover 31 provides unified positioning and fixing of multi-layer components, making the installation process between the lamp board 2, the main control board 5 and the first lamp cover 31 more convenient and reliable, reducing assembly steps and the probability of errors.

[0094] In one embodiment, the air pump further includes a shroud 9, which is connected to the motor bracket 80 and has a through hole as the air outlet of the air pump. The shroud 9 and the second lamp cover 32 together form a fluid cavity in the installed state, so that the gas compressed by the impeller 6 can be smoothly discharged through the through hole of the shroud 9, thereby achieving a stable air pump output function.

[0095] The through holes of the fairing 9 can be configured as round holes, rectangular holes, elliptical holes, etc., according to the airflow requirements. Different hole shapes can be used to regulate the flow rate and disperse the airflow, resulting in more stable exhaust, lower noise, and reduced turbulence at the exhaust end. The cavity formed by the second lampshade 32 not only serves as a guide but also reduces the direct impact of airflow on the inner side of the lampshade to a certain extent, thereby extending the service life of the lampshade and avoiding material fatigue or deformation caused by airflow erosion.

[0096] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
