Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a ring controller. Background Technology

[0002] Vertical electrical appliances (such as vertical lamps and vertical therapy lamps) are characterized by their flexibility, adaptability, and versatility; in particular, their aesthetically pleasing appearance and space-saving design have led to their widespread use in modern life. Common vertical electrical appliances typically employ a functional structure, with the upright and base connected sequentially. However, most vertical appliances lack a convenient transport mechanism. Therefore, when users need to move these appliances, they usually have to hold the upright by hand, which is inconvenient and significantly impacts the user experience.

[0003] Furthermore, traditional vertical electrical appliances typically mount their controllers on a pole for on / off control. These controllers often feature elongated, irregularly shaped structures for aesthetic purposes, which can obstruct the most easily gripped area of ​​the pole, making them more inconvenient to move. Moreover, the controllers of traditional vertical appliances are easily bumped during transport, leading to accidental activation or damage.

[0004] For floor-standing appliances, which are often used in dark environments, the controller is frequently difficult to discern in the dark, making it challenging for users to perform accurate and timely control operations. Consequently, some electronic devices incorporate luminous elements to indicate operating status and provide fault warnings. For example, luminous elements are commonly used in the controllers of lamps and infrared therapy lamps to indicate operating status; red light indicates the appliance is on, and the color and brightness of the luminous element can be adjusted to represent different operating states, improving the user's visual experience.

[0005] In existing technologies, LED light sources have advantages such as long lifespan, small size and light weight, low power consumption, low cost and high brightness, which makes them suitable for a wide range of applications and can be used as light-emitting components to transmit light outward. However, since LED light sources are point light sources, while they have high brightness, it is also difficult to distribute the emitted light evenly within a specific range. Moreover, LED light sources are usually mounted on circuit boards to achieve vertical illumination of light-transmitting components. However, due to the close distance between the LED light source and the light-transmitting component, effective light dispersion is not possible, resulting in poor light uniformity and the appearance of discrete strong light spots on the light-transmitting component, which seriously affects the user experience. In particular, the drawbacks of these strong light spots are more obvious in dark environments.

[0006] Therefore, there is an urgent need for a new controller that can achieve an aesthetically pleasing design while improving the user experience. Utility Model Content

[0066] 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 are not limited to the following embodiments.

[0067] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the ring controller of this utility model can realize the switching control of external functional components through connection with external support structure and circuit; it includes: housing 1, control switch 2 disposed on housing 1, control circuit 3 and buzzer 4 installed in housing 1; in this embodiment, housing 1 is the main support structure of the entire ring controller, used to install control switch 2, control circuit 3 and buzzer 4, and housing 1 also realizes detachable connection with external support structure.

[0068] In this embodiment, the housing 1 includes: an outer housing support 11, a housing cover 12, and a light guide ring 13. The outer housing support 11 is an annular structure, and the outer housing support 11 and the housing cover 12 are coaxially arranged. Specifically, the housing cover 12 and the outer housing support 11 are detachably installed inside the outer housing support 11, forming a hollow cavity between them. The control circuit 3 and the buzzer 4 can be installed within this cavity to achieve internal integration of functional components. In this embodiment, along the axial direction of the outer housing support 11, the first end of the housing cover 12 is fastened to the outer housing support 11, and the second end of the housing cover 12 is connected to the outer housing support 11 abutting against the light guide ring 13.

[0069] In this embodiment, the control circuit 3 and the buzzer 4 are respectively connected to the outer support 11 of the housing to ensure the reliable fixation of their installation positions. The control circuit 3 is mechanically connected to the outer support 11 (e.g., by a threaded connector), and the buzzer 4 is also mechanically connected to the outer support 11 (e.g., by adhesive bonding, threaded connectors, etc.). In this embodiment, the control circuit 3 is equipped with LED beads 31, which are positioned opposite to the light guide ring 13. The light emitted by the LED beads 31 propagates through the light guide ring 13, achieving the effect of the entire light guide ring 13 illuminating. Furthermore, the control circuit 3 is electrically connected to the control switch 2 and the buzzer 4. The control switch 2 enables functions such as switching on / off and selecting function modes, while the buzzer 4 can emit different alert sounds under controlled conditions.

[0070] Combination Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, according to one embodiment of the present invention, the light guide ring 13 is detachably nested with the second end of the housing cover 12; wherein, the light guide ring 13 includes: a light distribution ring 131 and a receiving protrusion 132. In this embodiment, the light distribution ring 131 and the receiving protrusion 132 can be configured as a single unit to facilitate reliable light propagation. Furthermore, the radial dimension of the uniform light ring 131 at one end of the receiving cavity is smaller than that at the other end. Specifically, the uniform light ring 131 can achieve its size reduction effect by radially step-down reduction, and includes: a first annular portion 1311, a second annular portion 1312, and a third annular portion 1313. In this embodiment, the first annular portion 1311, the second annular portion 1312, and the third annular portion 1313 are coaxially arranged. Along the axial direction of the uniform light ring 131, the first annular portion 1311 and the third annular portion 1313 are staggered. Furthermore, the radial dimension of the third annular portion 1313 is smaller than that of the first annular portion 1311. And, along the radial direction of the uniform light ring 131, the opposite sides of the second annular portion 1312 are fixedly connected to the ends of the third annular portion 1313 and the first annular portion 1311, respectively, thereby completing the configuration of the entire uniform light ring 131.

[0071] In this embodiment, the first annular portion 1311 and the third annular portion 1313 can be respectively configured as columnar rings, and correspondingly, the second annular portion 1312 can be configured as a plate-shaped ring. This allows the radial direction of the second annular portion 1312 to be perpendicular to the axial direction of the first annular portion 1311 and the third annular portion 1313, respectively, thus achieving a stepped configuration of the entire uniform light ring 131. Alternatively, the second annular portion 1312 can be configured as a conical ring, allowing it to connect to the first annular portion 1311 via its large-diameter end and to the third annular portion 1313 via its small-diameter end. In another embodiment, the first annular portion 1311 and the third annular portion 1313 can also be selectively configured as conical rings. Therefore, by using different forms of the first annular portion 1311, the second annular portion 1312, and the third annular portion 1313, adaptation to the installation position can be achieved, effectively improving the installation accuracy and reliability of this invention.

[0072] Combination Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, according to one embodiment of the present invention, along the radial direction of the uniform light ring 131, the first annular portion 1311 is fitted onto the radial outer side of the second end of the housing cover 12; along the axial direction of the uniform light ring 131, the second annular portion 1312 is abutted against the side of the second end of the housing cover 12.

[0073] According to another embodiment of the present invention, the uniform light ring 131 can adopt a conical ring structure as a whole to achieve the effect of reducing its size. Its structural configuration is a common conical ring, which will not be described in detail here.

[0074] According to one embodiment of the present invention, the uniform light ring 131 can be a circular ring, an elliptical ring or other forms of ring, and its overall form can be adapted based on the installation position.

[0075] Combination Figure 7 , Figure 8 and Figure 9 As shown, according to one embodiment of the present invention, along the axial direction of the light-diffusing ring 131, a receiving protrusion 132 is disposed on the end face of the third annular portion 1313 away from the second annular portion 1312. In this embodiment, along the axial direction of the light-diffusing ring 131, the end face of the receiving protrusion 132 away from the third annular portion 1313 is a light-receiving surface, and the light-receiving surface is concave; wherein, the light-receiving surface is disposed opposite to the light-emitting lamp bead 31 to achieve the reception of light emitted by the light-emitting lamp bead 31. In this embodiment, the light-diffusing ring 131 and the receiving protrusion 132 are made of PC material, thereby achieving both light reception and conduction and uniform internal distribution of light to achieve the lighting effect of the light guide ring 13.

[0076] In this embodiment, along the circumference of the light-receiving ring 131, the vertical distance between the two ends of the light-receiving surface and the light-receiving ring 131 is greater than the vertical distance between the middle position of the light-receiving surface and the light-receiving ring 131, so that the end face of the receiving protrusion 132 is concave, thereby effectively increasing the circumferential length of the light-receiving surface, making it easier to receive the light emitted by the light-emitting lamp bead 31. In addition, by setting the light-receiving surface as concave, it is easier to adjust the spacing between the light-receiving surface and the light-receiving lamp bead 31, thereby better achieving a partial enclosure of the light-emitting surface of the light-emitting lamp bead 31, so that the received light can be more evenly distributed on the light-receiving surface, which is more beneficial to the uniform transmission of light in the light-receiving ring 131.

[0077] In this embodiment, the size of the light-receiving surface is larger than the size of the light source opposite it, thereby enabling the light-receiving surface to have sufficient receiving capacity. Furthermore, the light-receiving surface has an axisymmetric structure along the radial direction of the uniform light ring 131, which makes it easier to align the light-receiving surface and the light source along the axis of symmetry, thereby making the received light more uniform and further improving the uniform ring distribution of the received light in the uniform light ring 131.

[0078] In this embodiment, the light-receiving surface can be configured as one of a circular arc surface, an elliptical arc surface, or a parabolic surface. By flexibly setting the concave shape of the light-receiving surface, the position between the light-receiving surface and the light source can be flexibly matched, thereby achieving uniform light reception. In this embodiment, the concave shape of the light-receiving surface is set as a circular arc surface, which conveniently reduces the processing difficulty of the light-receiving surface and lowers its production cost.

[0079] like Figure 7 As shown, according to one embodiment of the present invention, the circumferential length of the light-receiving surface gradually decreases along the direction from the radially outer side to the radially inner side of the third annular portion 1313. This results in the projection of the light-receiving surface exhibiting a fan-shaped pattern. Consequently, the light-receiving surface can more easily match the dimensions of the end face of the receiving protrusion 132 arranged in the light-diffusing ring 131, thereby more conveniently and uniformly transmitting the received light into the light-diffusing ring 131.

[0080] Furthermore, in the radial direction of the light-diffusing ring 131, the width of the receiving protrusion 132 is consistent with the width of the end of the receiving protrusion 132 arranged on the third annular portion 1313. This ensures that the projection of the light-receiving surface coincides with the end face of the light-diffusing ring 131, thereby guaranteeing the efficiency of light transmission. In addition, by making the width of the receiving protrusion 132 consistent with the width of the end of the receiving protrusion 132 arranged on the light-diffusing ring 131, the two sides of the receiving protrusion 132 in the width direction are flush with the sides of the light-diffusing ring 131, effectively avoiding light leakage at the connection point and making the light transmission path more reliable.

[0081] Furthermore, along the direction away from the third annular portion 1313, the outer surfaces 1321 of the protrusions at both circumferential ends of the receiving protrusion 132 are inclined towards each other. This arrangement significantly increases the angle between the outer surfaces 1321 and the light-receiving surface. Thus, while the light-receiving surface receives external light, a portion of the light is reflected over a wide area by the inclined outer surfaces 1321, resulting in a broad distribution of the input light and improving the distribution range of the light entering the uniform light ring 131. In this embodiment, the outer surfaces 1321 are planar or curved.

[0082] Furthermore, along the direction from the radial outer side to the radial inner side of the third annular portion 1313, the protrusion height of the receiving protrusion 132 away from the third annular portion 1313 gradually decreases, so that the light-receiving surface is inclined relative to the uniform light ring 131. This results in a certain tilt angle between the light-receiving surface and the radial outer side of the uniform light ring 131, allowing the light received by the light-receiving surface to be transmitted to the radial outer side of the uniform light ring 131, thereby achieving the effect of uniform light transmission through reciprocating reflection between the radial outer side and the radial inner side of the uniform light ring 131.

[0083] like Figure 7 As shown, according to one embodiment of the present invention, the outer surface 1321 of the protrusion is a reflective mirror surface; by setting the outer surface 1321 of the protrusion on both sides of the receiving protrusion 132 as a smooth mirror surface, the reflection efficiency of light is improved, so as to fully ensure the propagation of light to the uniform light ring 131.

[0084] like Figure 7 As shown, according to one embodiment of the present invention, multiple receiving protrusions 132 are equally spaced along the circumference of the third annular portion 1313, and correspondingly, light-emitting lamp beads 31 are arranged one-to-one with the receiving protrusions 132 to realize the illumination setting of the receiving protrusions 132 respectively.

[0085] With the above-mentioned arrangement, by setting multiple receiving protrusions 132 in the circumferential direction of the third annular portion 1313, the position of the received light can be effectively increased, thereby making it easier for the received light to be evenly distributed in the light-averaging ring 131. Furthermore, the brightness and color of the entire light guide ring can be adjusted by controlling the number of light source switches and the type of light source, making the light-averaging and light-guiding effects of this invention even better.

[0086] Combination Figure 7 and Figure 8 As shown, according to one embodiment of the present invention, a first chamfered reflective surface 1313a is provided at the end where the third annular portion 1313 connects to the second annular portion 1312; a second chamfered reflective surface 1311a is provided at the end where the first annular portion 1311 connects to the second annular portion 1312; in this embodiment, the first chamfered reflective surface 1313a and the second chamfered reflective surface 1311a are conical annular surfaces; wherein, the first chamfered reflective surface 1313a and the second chamfered reflective surface 1311a are arranged opposite to each other, and the first chamfered reflective surface 1313a is arranged opposite to the receiving protrusion 132. Therefore, the external light received by the light-receiving surface on the receiving protrusion 132, after being conducted through the third annular portion 1313, is reflected into the second annular portion 1312 based on the first chamfered reflective surface 1313a. Further, after propagation through the second annular portion 1312, the light is reflected by the second chamfered reflective surface 1311a and enters the first annular portion 1311. This achieves sequential propagation of light from the receiving protrusion 132, the third annular portion 1313, the second annular portion 1312, and the first annular portion 1311, thereby ensuring the propagation and uniform distribution of external light. In this embodiment, the radially adjacent sides of the third annular portion 1313, the axially adjacent sides of the second annular portion 1312, and the radially adjacent sides of the first annular portion 1311 are all reflective mirrors, thereby achieving a uniform distribution effect through repeated reflection of light during transmission.

[0087] In this embodiment, the first chamfered reflective surface 1313a and the second chamfered reflective surface 1311a have the same tilt angle. As a result, the first chamfered reflective surface 1313a and the second chamfered reflective surface 1311a are arranged coaxially and parallel to each other, thereby making the transmission of light more sufficient and reliable.

[0088] Combination Figure 7 and Figure 8 As shown, according to one embodiment of the present invention, the end face of the first annular portion 1311 away from the second annular portion 1312 is a light-emitting surface, and the light-emitting surface is arranged opposite to the second chamfered reflective surface 1311a.

[0089] With the above settings, the light-emitting surface can fully receive the transmitted light to achieve a uniform distribution on the light-emitting surface, thus achieving the effect of uniform lighting along the ring.

[0090] It should be noted that the other sides of the first annular portion 1311, the second annular portion 1312, and the third annular portion 1313 that are different from the light-emitting surface, the first chamfered reflective surface 1313a, and the second chamfered reflective surface 1311a can be optionally set as smooth mirror surfaces to achieve reciprocating reflection of internal light. Correspondingly, in order to achieve a uniform light effect on the light-emitting surface, the roughness of the light-emitting surface can be set to be greater than that of the other surfaces to achieve a diffuse reflection effect on the entire light-emitting surface, thereby achieving a better uniform light effect.

[0091] Combination Figure 7 and Figure 8 As shown, according to one embodiment of the present invention, the light-emitting surface is a conical annular surface; wherein, along the direction from the first annular portion 1311 to the third annular portion 1313, the radial dimension of the light-emitting surface gradually decreases. In this embodiment, the angle between the light-emitting surface and the axial direction of the light-averaging ring 131 is greater than the angle between the second chamfered reflective surface 1311a and the axial direction of the light-averaging ring 131. Through the above arrangement, the light-emitting surface is generally arranged at an angle, thereby increasing the effective area for light emission and making it easier to uniformly receive the light to be output. In addition, the light-emitting surface can also be combined with other structures to achieve a better visual effect.

[0092] Combination Figure 1 , Figure 5 , Figure 9 and Figure 10As shown, according to one embodiment of this utility model, the shape of the outer support 11 can be flexibly set as needed. For example, the outer support 11 can be set as a circular ring, an elliptical ring, etc. Correspondingly, the shapes of the housing cover 12 and the light guide ring 13 are adapted to the shape of their installation positions on the outer support 11 to achieve continuity of the outer surfaces of the outer support 11, the light guide ring 13, and the housing cover 12 after installation. In this embodiment, the cross-section of the housing cover 12 is semi-circular, semi-elliptical, semi-rectangular, etc. In the axial direction of the outer support 11, the first end and the second end of the housing cover 12 can follow its curved shape so that the first end and the second end are opposite each other, thereby achieving fitting installation with the light guide ring 13 and the ends of the outer support 11 respectively. This ensures the smooth continuity of the entire controller housing surface, effectively ensuring the integrity and smoothness of the entire controller housing shape while achieving complete closure of the formed receiving cavity.

[0093] In this embodiment, the housing cover 12 includes a first cover 121 and a second cover 122; wherein the first cover 121 and the second cover 122 are both annular structures, and the first cover 121 and the second cover 122 are coaxially connected; in this embodiment, along the axial direction of the outer support 11 of the housing, the length of the first cover 121 and the length of the second cover 122 can be set to be the same, thereby making the mating position of the first cover 121 and the second cover 122 in the middle position, so that the installation of the first cover 121 and the second cover 122 is easier. In addition, by dividing the first cover 121 and the second cover 122 in the middle position, the forming of each part can be improved, and the overall smoothness of the shape of the entire housing cover 12 can be controlled, making the outer surface formed by this invention smoother.

[0094] In this embodiment, the end of the first cover 121 away from the second cover 122 constitutes the first end of the housing cover 12; the end of the second cover 122 away from the first cover 121 constitutes the second end of the housing cover 12.

[0095] Combination Figure 3 , Figure 4 , Figure 5 and Figure 9As shown, according to one embodiment of the present invention, the first cover 121 and the second cover 122 are connected by a snap-fit ​​connection. In this embodiment, the first cover 121 and the second cover 122 are connected to each other by a first snap-fit ​​structure A that is detachable from each other; wherein, the first snap-fit ​​structure A includes: a first protrusion A1 and a first buckle A2; wherein, the first buckle A2 is generally plate-shaped and has a fastening hole penetrating its body; in this embodiment, the first buckle A2 is disposed on the inner side of the end of the first cover 121, one end of which is fixedly connected to the first cover 121, and the other end extends toward the second cover 122. Accordingly, in order to ensure a stable and reliable fastening between the first buckle A2 and the first protrusion A1, the position of the fastening hole on the first buckle A2 is offset from the end of the first cover 121 to avoid interference with the end of the first cover 121. Furthermore, the first protrusion A1 is provided on the inner side of the end of the second cover 122, wherein the installation position of the first protrusion A1 on the second cover 122 corresponds to the position of the fastening hole after the first cover 121 and the second cover 122 are mated together, thereby facilitating a convenient and reliable fastening connection between the first protrusion A1 and the first buckle A2. In another embodiment, the installation positions of the first protrusion A1 and the first buckle A2 on the housing cover 12 can be interchanged, that is, the first protrusion A1 can be provided on the first cover 121, and the first buckle A2 can be provided on the second cover 122.

[0096] In this embodiment, an inclined guide surface is provided on the side of the first protrusion A1 opposite to the first cover 121. Thus, during the process of the first cover 121 and the second cover 122 coming together, the first buckle A2 can be elastically bent upward based on the abutting action between the inclined guide surface on the first protrusion A1 and the end of the first buckle A2. Until the first cover 121 and the second cover 122 are connected, the buckling hole on the first buckle A2 is aligned with the first protrusion A1, and under the elastic action, the first buckle A2 rebounds and achieves a buckling connection with the first protrusion A1.

[0097] In this embodiment, multiple first snap-fit ​​structures A are provided at equal intervals along the circumference of the housing cover 12, so that the connection between the first cover 121 and the second cover 122 is more reliable.

[0098] Combination Figure 3 , Figure 4 , Figure 5 and Figure 9As shown, according to one embodiment of the present invention, the ends of the first cover 121 and the second cover 122 are abutted together using a stepped structure. In this embodiment, annular protrusions are provided at the ends of the first cover 121 and the second cover 122 respectively, so that the ends of the first cover 121 and the second cover 122 form a stepped structure that fits together. This effectively ensures the docking accuracy and reliability of the connection between the ends of the first cover 121 and the second cover 122. Specifically, a first annular protrusion is provided at the end of the first cover 121, and a second annular protrusion is provided at the end of the second cover 122. The radial dimension of the first annular protrusion is larger than that of the second annular protrusion, so that when the first cover 121 and the second cover 122 are docked together, the first annular protrusion and the second annular protrusion are nested together to ensure the realization of the corresponding stepped structure. Furthermore, to ensure the surface flatness and shape consistency of the docking position, the radial dimension of the first annular protrusion and the second annular protrusion after being nested together can be made consistent with the radial dimension of the ends of the first cover 121 and the second cover 122, so as to effectively ensure the smoothness and integrity of the surface.

[0099] According to another embodiment of the present invention, the first cover 121 and the second cover 122 are fixedly connected by adhesive. Specifically, the ends of the first cover 121 and the second cover 122 that meet each other are bonded together by applying glue.

[0100] According to another embodiment of the present invention, the first cover 121 and the second cover 122 are connected by an interference fit.

[0101] It should be noted that the first cover 121 and the second cover 122 can be connected using one of the following methods: snap-fit ​​connection, adhesive bonding, or interference fit. Alternatively, multiple methods can be used, such as a combination of snap-fit ​​connection and adhesive bonding, to achieve mutual fixation. This combined approach further ensures the reliability and sealing of the connection.

[0102] Combination Figure 3 , Figure 4 , Figure 5 and Figure 9As shown, according to one embodiment of the present invention, an outer support docking buckle 121a is provided at one end of the first cover 121 that engages with the outer support 11 of the housing; wherein, the outer support docking buckle 121a includes: an annular connecting portion 121a1 and a buckle docking portion 121a2.

Thus, a corresponding annular abutment portion can be formed between the annular connecting portion 121a1 and the end edge of the first cover 121, thereby facilitating the abutment between the end of the first cover 121 and the outer support 11 of the housing when the first cover 121 is connected to the outer support 11 of the housing. Correspondingly, the outer diameter of the annular connecting part 121a1 can be set to be consistent with the inner diameter of the outer support 11 of the housing. Thus, after the first cover 121 is installed with the outer support 11 of the housing, the annular connecting part 121a1 can be coaxially positioned with the inner side of the outer support 11 of the housing, thereby effectively ensuring the installation accuracy and sealing of the first cover 121, which is more beneficial to ensuring the smoothness and continuity of the shape.

[0103] In this embodiment, multiple snap-fit ​​docking portions 121a2 are provided at equal intervals along the circumference of the annular connecting portion 121a1; for example, the snap-fit ​​docking portions 121a2 can be configured as two, three, four, etc. Further, the snap-fit ​​docking portion 121a2 includes: a first connecting plate 121a21 and a first snap-fit ​​protrusion 121a22; wherein, one end of the first connecting plate 121a21 is fixedly connected to the annular connecting portion 121a1, and the other end is an extension end extending away from the annular connecting portion 121a1; in this embodiment, the side of the first connecting plate 121a21 facing the outer support 11 of the housing can be configured as an arc surface, so that the outer surface of the first connecting plate 121a21 is flush with the annular connecting portion 121a1; thereby, the surface of the first connecting plate 121a21 can match the inner side of the outer support 11 of the housing. Furthermore, the first snap-fit ​​protrusion 121a22 is arranged on the side of the extended end of the first connecting plate 121a21 facing the outer support 11 of the housing. In this embodiment, along the axial direction of the annular connecting portion 121a1, the end of the first snap-fit ​​protrusion 121a22 opposite to the annular connecting portion 121a1 is provided with an inclined guide surface. Thus, during the installation of the first cover 121, the first connecting plate 121a21 can be elastically bent by the provided guide surface, so that the snap-fit ​​mating portion 121a2 can be easily installed in place, thereby ensuring a reliable engagement between the snap-fit ​​mating portion 121a2 and the outer support 11 of the housing.

[0104] like Figure 9 As shown, according to one embodiment of the present invention, multiple reinforcing ribs can be provided at equal intervals on the inner side surface of the first cover 121 along the circumferential direction of the first cover 121 to achieve stable maintenance of the structural shape of the first cover 121.

In this embodiment, multiple first positioning members 122a are equally spaced along the circumference of the second cover 122, such as two or three, to facilitate reliable positioning of the second cover 122.

[0106] Furthermore, to further ensure reliable installation of the second cover 122, a threaded connecting post 122b can be provided on the inner side of the second cover 122. The threaded connecting post 122b is spaced apart from the end edge of the second cover 122 along the radial direction of the second cover 122.

[0119] Preferably, the axial direction of the sound outlet 111f1 is parallel to the axial direction of the second connecting sleeve 113, thereby allowing the sound outlet 111f1 to be positioned facing the ground.

[0120] The above-mentioned design effectively improves the waterproof and dustproof performance of this invention, effectively preventing external dust or water droplets from flowing into the ring controller through the sound outlet 111f1, thus ensuring the reliability of this invention.
