Description

Technical Field

[0001] This utility model relates to the field of decorative lighting technology, specifically to a decorative lamp that has the advantages of simple installation and high safety. Background Technology

[0002] Currently, the typical structure of letter lights on the market is as follows: a light groove is machined into the base plate according to the preset letter shape (usually using processes such as engraving or CNC milling). During installation, the segmented flexible light strip in roll form needs to be manually cut and fixed to the base plate and then connected to the power supply.

[0003] However, this traditional structure has significant drawbacks:

[0004] 1. Complex splicing and low reliability: It relies on manual physical splicing of multiple flexible light strips in the light trough, which is prone to frequent failures due to misalignment, loose connectors or poor soldering.

[0005] 2. The process is cumbersome and costly: The production process requires manual cutting of the LED strips and sealing strips from the roll material and then gluing and fixing them together section by section. This process is inefficient and labor costs account for a high proportion of the total cost.

[0006] 3. Poor adaptability and installation difficulties: When the light trough involves small bending radii or continuous complex curves, rigid / semi-rigid segmented light strips are difficult to fit perfectly. Workers are often forced to further cut the light strips and sealing strips into shorter segments, and even need to use temporary wires similar to "flying wires" to make jumpers between some of the smaller segments. This not only significantly increases working time and difficulty, but also introduces additional risk points of connection failure.

[0007] 4. Fragile structure and significant safety hazards: The adhesive seal, which is the main means of fixing the letter light, is easily delaminated and detached during subsequent handling, installation, and use due to stress, temperature differences, or aging. Once the seal fails, the light strip may shift, loosen, or even expose live parts, posing serious electrical safety (such as short circuits and electric shocks) and mechanical safety (such as tripping and falling parts) hazards. Summary of the Invention

[0008] This utility model provides a decorative lamp to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] This utility model relates to a decorative lamp, including a base plate, an integrally formed lamp panel, and a lampshade. The base plate is provided with a lamp groove, which is formed according to a preset shape and has an inner cavity contour and an inner wall. The shape of the lamp panel matches the inner cavity contour of the lamp groove, and a light-emitting element is provided on the lamp panel. The entire lamp panel is placed inside the lamp groove. The lampshade covers the lamp groove and is connected to the base plate. The lampshade includes an embedding part located inside the lamp groove. The embedding part abuts against the inner wall of the lamp groove to constrain the position of the lampshade itself. The lamp panel is accommodated in the lamp groove, so that the lampshade constrains the lamp panel inside the lamp groove through the abutment between the embedding part and the inner wall of the lamp groove.

[0011] The advantages of this utility model over the prior art are as follows: through the coordinated design of the three core components (base plate, integrated lamp plate, and mechanically snap-fit ​​lampshade), a breakthrough in the production process of splicing-free, glue-free, and two-step rapid assembly is achieved, which mainly solves the problems of easy damage to splicing points, aging and failure of adhesive, and complex assembly process in traditional decorative lights.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. The following description of at least one exemplary embodiment is illustrative in nature and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0033] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as exemplary rather than limiting. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0034] Referring to the accompanying drawings, an exemplary embodiment is shown, illustrating a novel decorative lamp structure that fundamentally eliminates segmented splicing and adhesive fixing methods, aiming to achieve the elimination of splicing points and fragile adhesive structures.

[0035] like Figure 1 As shown in the exemplary embodiment, this first embodiment illustrates the specific structure of a decorative lamp 100. The decorative lamp 100 mainly includes: a base plate 10, a light-emitting component (not shown) mounted on the base plate 10, and a lampshade 30 covering the light-emitting component and connected to the base plate 10. The base plate 10, the light-emitting component, and the lampshade 30 work together to enable the decorative lamp 100 to clearly present a preset graphic to the user. For example, Figure 1 The image shows the decorative lamp 100 forming the letter "E" with its light-emitting effect. This preset graphic is mainly achieved through a specially designed light-transmitting area (or light-shielding pattern) on the lampshade 30. When the light-emitting component is lit, light passes through a specific area of ​​the lampshade 30 and projects the desired graphic outline.

[0036] It should be noted that the decorative light 100 described in this utility model has a wide range of applications. Its core feature lies in achieving customized graphic illumination through the aforementioned structure. Typical applications include, but are not limited to: support light boards (such as fan gatherings and concert venues), commercial sign lights (shop signage, advertising), ambient decorative lights (festival decorations, home embellishments), and directional sign lights. Its core value lies in its ability to flexibly and efficiently display specific patterns or text information required by the user.

[0037] Please refer to the following: Figure 2 , Figure 3 The decorative lamp base plate 10 in this application is its core supporting structure, manufactured using a one-piece injection molding process. This process not only ensures that the base plate 10 has excellent overall structural strength and load-bearing capacity, significantly improving the durability and service life of the decorative lamp 100, but also facilitates the realization of complex shapes. The overall shape of the base plate 10 is carefully designed to match the target shape that the decorative lamp is intended to display (e.g., Figure 1 The design closely resembles the letter "E" in the logo. This design echo makes the base plate itself part of the aesthetic design, significantly enhancing the overall visual appeal and thematic expression of the decorative lamp 100.

[0038] The base plate 10 has a top surface 101 and a bottom surface (not shown in the attached drawings). For ease of suspension, the upper half of the base plate 10 has two first through holes 102. These holes penetrate the base plate 10, connecting the top surface 101 and the bottom surface. The center distance between the two first through holes 102 is precisely controlled within the range of 8-12 cm. This standardized spacing design adapts to common suspension hook distances, improving the product's versatility.

[0039] Please refer to the following: Figure 4 Each first through hole 102 consists of two parts (e.g. Figure 4 (Clearly illustrated): The first hole 1021 is located at the top, and its size is smaller than the second hole 1022 below. One side of the first hole 1021 is designed to be semi-circular to facilitate hook insertion or provide directional positioning. The second hole 1022 is located directly below the first hole 1021, and has a larger, circular structure. The first hole 1021 and the second hole 1022 overlap vertically and are interconnected, forming a continuous suspension channel. This composite structure, with a smaller top and a larger bottom, helps to secure or guide the suspension components.

[0040] Three second through holes 103 are provided in the lower half of the base plate 10. These holes also penetrate the base plate 10, connecting the top surface 101 and the bottom surface, and are designed in a square shape. The three second through holes 103 are distributed at intervals along the longitudinal direction (from top to bottom) of the base plate 10. The center distance between two adjacent second through holes 103 is controlled within the range of 0.3-1 cm. This compact and precise spacing provides wiring flexibility. The core function of the second through holes 103 is to serve as the entry and exit point for the power cord, allowing the light-emitting components inside the decorative light 100 to be safely connected to an external power source or control device via wires. When the power cord used for connection is short, the user can choose the second through hole 103 closest to the connection point of the internal light-emitting component (usually the one with the highest position) as the wire outlet. This maximizes the use of the short cord length and avoids connection failure due to the short cord. When the power cord is long, the user can flexibly choose the second through hole 103 with a lower position as the wire outlet according to the actual location of the external device (such as a socket or controller). This design greatly optimizes the user experience: it effectively shortens the length of the exposed power cord between the decorative light 100 body and external devices, reduces redundant cables, makes the installation neater and more aesthetically pleasing, and greatly simplifies the work of cable storage and organization, improving the product's practicality and spatial coordination.

[0041] Specifically, two sets of upward-extending sidewalls 104 (i.e., extending away from the base plate 10) are provided on the top surface 101 of the base plate 10. These two sets of sidewalls 104 together enclose a light groove 105 for accommodating light-emitting components (such as LED light strips). The sidewalls 104 are manufactured using an integral injection molding process with the base plate 10, ensuring the integrity and strength of the structure. All sidewalls 104 have the same wall height, and the actual depth of the light groove 105 is equal to this wall height, both designed within the range of 0.5-1 cm. This depth range is optimized to effectively hide and protect the light-emitting components while ensuring that light can pass through appropriately, forming a clear light path outline.

[0042] The core of this design lies in the path planning of the light trough 105. For example... Figure 4 As shown, the overall path of the light trough 105 is carefully designed to perfectly match the target decorative shape (e.g., an "E" shape). When the user looks down at the decorative light 100, the clearly discernible light trough path outlined by the light-emitting elements visually presents the predetermined target shape (e.g., an "E"). It should be emphasized that the target shape is highly flexible and not limited to the "E" shape example; it can be designed as any letter (e.g., A, B), number, symbol, or specific pattern shape (e.g., ...) according to actual application needs. Figure 5 , Figure 6 , Figure 7 (As shown).

[0043] In this embodiment, a first through hole 102 is specifically provided. This hole is located within the shape path formed by the light trough 105 (e.g., between the strokes of an "E" shape). It is worth noting that the path of the light trough 105 is actually arranged around the first through hole 102. The main purpose of providing the first through hole 102 is to provide a suspension point, facilitating the installation and fixing of the decorative lamp 100 (e.g., suspension with a rope). Its position is carefully selected to ensure that it is located in the "blank" area formed by the light trough path, so it will not interfere with the arrangement of the light-emitting elements and the light effect within the light trough 105, nor will it significantly affect the structural strength of the base plate 10. This means that, while satisfying the suspension function, the specific position of the first through hole 102 on the base plate 10 can be flexibly adjusted according to the shape requirements and mechanical analysis.

[0044] Combination Figure 8 , Figure 9 As shown, a light panel 106 serving as a light source is installed inside the light trough 105. The light panel 106 adopts a one-piece molding design, and its overall outline is precisely adapted to the shape of the light trough 105, together forming the target shape (in this embodiment, the target shape path presents an approximate "E" shape). When the user looks down, they can clearly see that the shape of the light panel 106 is highly consistent with the target shape presented by the decorative light 100.

[0045] In this embodiment, the lamp board 106 is a single, integral structure with multiple light-emitting elements 1061 spaced apart on it. The shape of the lamp board 106 perfectly matches the inner cavity shape of the lamp trough 105, and its overall size is designed to be no larger than the accommodating space of the lamp trough 105, ensuring easy placement within the lamp trough 105. Compared to solutions that rely on manual physical assembly of multiple light-emitting elements within the lamp trough (such as traditional LED strips), this design completely eliminates the risk of contact failures caused by misalignment, loose connectors, or poor soldering. The lamp board 106, as a complete light source output device, is ready to use out of the box, requiring no on-site assembly or soldering.

[0046] Specifically, the light-emitting elements 1061 are arranged on the surface of the lamp board 106 away from the base plate 10 and connected in series. In some embodiments, the light-emitting elements 1061 can also be connected in parallel; the integrated structure gives the lamp board 106 excellent deformation adaptability. Even if the design of the lamp trough 105 includes a very small bending radius or a continuous complex curved path, the lamp board 106 can perfectly fit the trough. This fundamentally avoids the "flying wire" jumper problem (i.e., using temporary wires to bridge discontinuities) common in traditional segmented solutions, significantly reduces the difficulty of the manufacturing process, and improves the long-term safety and reliability of the product. The lamp board 106 integrates a charging port 1063 (in this embodiment, a Type-C standard interface is used, directly soldered to the lamp board) for power input. A charging opening (not shown) is provided at the corresponding position on the side wall of the lamp trough 105 to ensure that the Type-C charging port 1063 is exposed to the outside world and can be directly connected to external power supply equipment. The lamp board 106 is also provided with a control component 1062, including control buttons 10621. Users can control the working status (such as on / off, mode switching, etc.) of the light-emitting element 1061 by pressing this button.

[0047] Combination Figure 10 , Figure 11 As shown, a lampshade 30 is installed within the light trough 105. The lampshade 30 is designed as a strip that matches the path of the light trough 105 (presented in this embodiment as an "E"-shaped target). When the lampshade 30 is in place, its sidewalls abut tightly against the inner wall of the light trough 105, forming a reliable constraint and ensuring that the lampshade itself is stably positioned within the light trough 105. The lamp plate 106 is precisely accommodated within the light trough 105, specifically between the base plate 10 and the lampshade 30. The lampshade 30 is carefully sized, slightly smaller than the opening of the light trough 105, allowing it to be smoothly inserted and self-positioned through sidewall contact. One of the core functions of the lampshade 30 is to securely restrain the lamp plate 106 within the light trough 105 through a mechanical structure. This represents a significant improvement over traditional fixing methods (such as those relying on adhesive seals).

[0048] The lampshade 30 consists of two main functional areas: an embedded part 301 and an exposed part 302. The embedded part 301 is located inside the lamp groove 105, and its sidewall abuts against the inner wall of the lamp groove to fix the lampshade itself. On the side of the embedded part 301 facing the base plate 10 (i.e., the side away from the exposed part 302), there is a limiting groove 303 that precisely matches the path of the lamp groove 105. When the lampshade 30 is installed in place, the lamp plate 106 is precisely embedded in this limiting groove 303. The design of the limiting groove 303 allows the lampshade 30 to not only limit the vertical position of the lamp plate 106 (preventing it from falling upwards), but also provides additional lateral restraint through the sidewall of the groove, significantly enhancing the fixing effect and seismic stability of the lamp plate 106. This "lamp groove-lampshade" collaborative mechanical constraint mechanism effectively avoids the risk of detachment caused by aging and vibration that may occur with traditional adhesive methods, thereby reducing safety hazards such as short circuits or electric shocks caused by lamp plate displacement. After the lampshade 30 is installed, the exposed portion 302 extends above the opening of the lamp trough 105, forming the visible light-emitting surface of the luminaire. The top edge of the exposed portion 302 features a rounded corner design. This structure not only enhances the aesthetics of the product but, more importantly, optimizes the light diffusion effect. It helps to soften and evenly scatter the light from the lower lamp panel 106, reducing glare and providing a more comfortable and uniform lighting experience.

[0049] The lampshade 30 has a control opening 304, which is precisely aligned with the control button 10621 on the lamp panel 106. When the lampshade 30 is installed, the top operating part of the control button 10621 passes through the control opening 304 and slightly protrudes from the exposed part 302 of the lampshade 30. Users can directly press the exposed part of the control button 10621 on the top of the lampshade to easily control the light-emitting element 1061 (such as switching, dimming, mode switching, etc.) without disassembling the lampshade or performing any additional operations, providing an intuitive and convenient user experience.

[0050] It should be noted that the base plate 10 and the light trough 105 that carries the target shape path are manufactured using a one-piece injection molding process. This ensures that the path of the light trough 105 accurately reproduces the target shape (such as the "E" shape in this embodiment) to be displayed by the decorative lamp 100. The lamp panel 106 adopts a one-piece pre-formed structure, and its shape precisely matches the inner cavity contour of the light trough 105. The lampshade 30 is also designed as a strip that conforms to the target shape path.

[0051] The assembly steps for the decorative lamp in this embodiment are as follows:

[0052] Step 1: The operator simply needs to place the pre-formed light panel 106 precisely into the light trough 105 according to the path direction of the target shape. The light panel 106, with its perfect fit to the light trough 105, can be easily and accurately positioned.

[0053] Step Two: Next, place the lampshade 30 above the light trough 105, following the same path direction as the target shape, and press it into the light trough 105 perpendicular to the base plate. The side wall of the insert portion 301 of the lampshade 30 abuts tightly against the inner wall of the light trough 105, achieving positioning and constraint of the lampshade itself. At the same time, the limiting groove 303 of the lampshade 30 (located on the bottom surface of the insert portion 301) perfectly accommodates and locks the lamp panel 106 below. The size design of the lampshade 30 ensures that after it is inserted, the lamp panel 106 is firmly fixed in the light trough 105 through the combined action of the side wall abutment and the limiting groove, without the need for any additional fasteners or adhesives.

[0054] After completing the above two steps, the core optical and structural components of the decorative lamp 100 are assembled.

[0055] The entire core assembly process involves only two intuitive placement actions (light panel -> lampshade), eliminating the need for complex wiring connections, physical splicing, welding, gluing, or screw tightening—traditional processes. This design significantly reduces the need for highly skilled workers and assembly time. It is simple and easy to learn, significantly reducing labor costs and improving production efficiency.

[0056] Key points of approval: The decorative lamp 100 shown in this utility model completely revolutionizes the traditional process in its production. Through optimized structural design and precise pre-forming of components, the core assembly can be completed in just two simple steps: "placing the lamp plate -> pressing in the lampshade". This achieves extreme simplification of the production process, effective control of labor costs, and a significant improvement in production efficiency, providing a strong advantage for large-scale production.

[0057] like Figure 12 , Figure 13 , Figure 14 , Figure 15 As shown: This exemplary embodiment 2 illustrates the specific structure of a neon light 200. The neon light 200 mainly includes a base plate 50, a light-emitting component (not shown) mounted on the base plate 50, and a lamp cover 60 covering the light-emitting component and connected to the base plate 50. The base plate 50, the light-emitting component, and the lamp cover 60 work together to enable the neon light 200 to clearly display a preset graphic, such as the illuminated letter "E" as shown in the figure.

[0058] The neon light 200 base plate 50 serves as the core support structure and is manufactured using an integrated injection molding process. Its overall shape is designed to be highly similar to the target shape (such as the letter "E").

[0059] The bottom shell plate 50 has a top surface 501 (bottom surface not shown). Two sets of upwardly extending extension walls 502 are provided on the top surface 501, together forming a receiving groove 503 for accommodating a light-emitting element (such as an LED light strip). The extension walls 502 are integrally formed with the bottom shell plate 50, ensuring structural integrity and strength. All extension walls 502 have the same height, and the depth of the receiving groove 503 is this height, designed within the range of 0.5-1 cm. This depth is optimized to effectively hide and protect the light-emitting element while ensuring adequate light transmission, forming a clear light path outline.

[0060] A light-emitting panel 70, serving as a light source, is installed within the receiving slot 503. This light-emitting panel 70 employs a one-piece molding design, with its overall outline precisely matching the shape of the receiving slot 503, together forming the target shape path (in this embodiment, it is approximately "E" shaped). When viewed from above, the user can clearly discern that the shape of the light-emitting panel 70 highly matches the target shape presented by the neon light 200.

[0061] The light-emitting board 70 is a single, integral structure with multiple light-emitting devices 701 spaced apart on it. Its shape perfectly matches the inner cavity of the receiving slot 503, and its overall size does not exceed the receiving space of the slot 503, facilitating convenient installation. Compared to traditional solutions that require manual assembly of multiple light-emitting components (such as LED strips) within the receiving slot 503, this design completely eliminates the risk of contact failures caused by misalignment, loose connectors, or poor soldering. The light-emitting board 70, as a complete light source output device, is ready to use out of the box, requiring no on-site assembly or soldering. The light-emitting board 70 also integrates a control component 702, including an operation button 7021, which allows users to control the on / off state and mode switching of the light-emitting devices 701 by pressing the button.

[0062] The lamp cover 60 consists of a covering portion 601 and an exposed portion 602. A covering groove 603 is formed on the side of the covering portion 601 away from the exposed portion 602, and its cavity contour is designed to closely match the target shape (such as an "E" shape). When the lamp cover 60 is installed, the receiving groove 503 is located within the covering groove 603, and its extended wall 502 abuts against the inner wall of the covering groove 603, thus securing the lamp cover 60 itself. The light-emitting panel 20 is precisely housed inside the receiving groove 503, located between the bottom shell plate 50 and the lamp cover 60. The receiving groove 503 is slightly smaller than the opening of the covering groove 603, allowing it to smoothly insert and achieve self-positioning through abutment against the inner wall of the covering groove 603. One of the core functions of the lamp cover 60 is to securely restrain the light-emitting panel 70 within the receiving groove 503 through a mechanical structure, marking a significant improvement over traditional methods relying on adhesive seals for fixation. Meanwhile, to enhance the fixing effect of the light-emitting plate 70, an abutment block 604 (the size of which is no larger than the opening of the covering groove 603) is provided inside the covering groove 603. When the lamp cover 60 covers the receiving groove 503, this abutment block 604 abuts against the light-emitting plate 70. In conjunction with the mechanical limiting structure of the lamp cover 60 and the receiving groove 503, the light-emitting plate 70 can be further stabilized.

[0063] The top edge of the exposed section 602 features a rounded corner design, which not only enhances aesthetics but also optimizes light diffusion. This helps soften and evenly diffuse the light emitted from the light-emitting panel 70, reducing glare and providing a more comfortable and uniform lighting experience.

[0064] The lamp cover 60 has a through hole 605, which is precisely aligned with the operation button 7021 on the light-emitting panel 70. After installation, the operating part of the operation button 2021 passes through the through hole 605 and protrudes slightly from the surface of the exposed part 602. The user can directly press the exposed part to conveniently control the light-emitting device 701 without removing the lamp cover 60.

[0065] It should be noted that the bottom shell plate 50 and the receiving groove 503 on it that carries the target shape path are manufactured using a one-piece injection molding process. This ensures that the path of the receiving groove 503 accurately reproduces the target shape (such as the "E" shape in this embodiment) to be displayed by the neon light 200. The light-emitting plate 70 adopts a one-piece pre-formed structure, and its shape precisely matches the inner cavity contour of the receiving groove 503. The lamp cover 60 is also designed as a strip body consistent with the target shape path, and has a covering groove 603 on it. The cavity contour of the covering groove 603 is carefully designed to highly match the target shape (such as the "E" shape).

[0066] The assembly steps of the neon light 200 in this embodiment are as follows:

[0067] Step 1: The operator precisely places the pre-formed light-emitting panel 70 into the receiving groove 503 along the target shape path. The light-emitting panel 70 can be easily and accurately positioned due to its matching shape with the receiving groove 503.

[0068] Step Two: Next, place the lamp cover 60 above the receiving groove 503 along the same target shape path direction, and cover the receiving groove 503 downwards in a direction perpendicular to the bottom shell plate 50. At this time: the inner wall of the covering groove 603 of the lamp cover 60 abuts tightly with the side wall of the receiving groove 503, realizing the positioning and constraint of the lamp cover 60 itself; at the same time, the abutting block 604 in the covering groove 603 cooperates with the bottom shell plate 50, which just completely restricts the light-emitting plate 70 below within the receiving groove 503; the size design of the covering groove 603 ensures that after it is covered, the light-emitting plate 20 can be firmly restricted without additional fasteners or adhesives through the action of the inner wall abutting against the side wall of the receiving groove 503 and the abutting block 604 and the bottom shell plate 50.

[0069] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms 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 on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0070] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotation or other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0071] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0072] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
