Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, specifically to a lamp and its processing mold, a floor brush head, and a vacuum cleaner. Background Technology

[0002] To facilitate observation of dust on the surface to be cleaned, a light for dust observation is usually installed on the front of the vacuum cleaner's floor brush head. Considering the size of the floor brush head and minimizing power consumption, a low-power light source is typically chosen for the floor brush head. To ensure that the light source can adequately illuminate the dust on the surface to be cleaned, a focusing mechanism is required.

[0003] Currently, most methods achieve this by placing a convex lens-shaped focusing structure in front of the LED chip. To reduce light loss in brightness and intensity, the dust cover area directly in front of this convex lens-shaped focusing structure is usually perforated; that is, the area of ​​the dust cover corresponding to the convex lens-shaped structure has a receiving hole to expose the structure. However, a gap inevitably forms between the focusing structure and the receiving hole, allowing dust to easily enter the lamp and affecting its lifespan.

[0004] Furthermore, existing vacuum cleaners have all lights on the front side with consistent range, angle of illumination, and brightness, thus creating only a sheet-like luminous area at the front of the vacuum cleaner (see...). Figure 9 As shown in the image, the light is still not focused enough, so even the finer dust particles on the cleaned surface cannot be clearly observed. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a lamp, comprising a light source and a protective cover disposed outside the light source, and a lampshade disposed in front of the light source. The light source and the lampshade are arranged sequentially along a first direction, and the lampshade is disposed on the protective cover.

[0006] The lampshade includes a first focusing portion, the outer surface of which is curved toward the side away from the light source.

[0007] The number of light sources is n, where n≥1, and one lampshade is provided for each light source. The number of curvature values ​​of the outer surface of each first light-concentrating part is ≥1.

[0008] This application has the following beneficial effects:

[0009] ① By setting the first focusing part of the lampshade on the protective cover, and bending the outer surface of the first focusing part toward the side away from the light source, a focusing structure similar to a convex lens is formed. Therefore, the focusing structure can be formed only during the processing of the protective cover, which facilitates the processing of the lampshade. Moreover, since the lampshade is formed on the protective cover, when the protective cover is set outside the light source, there will be no gap at the lampshade location of the protective cover, ensuring sufficient isolation between the light source and the external environment and effectively reducing dust from entering the lamp.

[0010] ② In this application, the number of curvature values ​​of the outer surface of each first focusing part is ≥1. Therefore, according to actual usage requirements, the curvature of the lampshade can be processed into first focusing parts with different curvatures during the initial processing, thereby achieving diversified light emission effects. When the number of light sources exceeds 1, if the number of curvature values ​​is set to be greater than 1, the lamp can emit light beams with different brightness or range, thus making it easier for users to observe the dust on the surface to be cleaned more clearly. In this application, the lampshade is set on the basis of the protective cover structure, which facilitates the processing of first focusing parts with diversified curvatures.

[0011] Furthermore, the distance d between any one of the light sources and its corresponding lampshade is defined as d, and the number of values ​​for d is ≥1. This allows the light emitted through the lampshade to have different ranges or beam focusing effects, satisfying more diverse application requirements for different emitted beams.

[0012] Furthermore, it also includes a second focusing section, which has a focusing cavity extending along a first direction. The first focusing section is disposed at the end of the focusing cavity near the light source, and the circumferential edge of the first focusing section is connected to the focusing cavity. Therefore, under the action of the second focusing section, the scattered light that still exists after passing through the first focusing section is further focused, thereby increasing the beam range and brightness, enabling the user to observe the fine particles on the surface to be cleaned.

[0013] Furthermore, the first focusing part is located within the focusing cavity. Therefore, the focusing cavity can effectively concentrate the light scattered by the first focusing part and emit it from the end of the focusing cavity furthest from the light source.

[0014] Furthermore, at least the inner wall of the focusing cavity is made of a material with reflective properties. This does not mean that a special reflective coating or other material needs to be applied to the inner wall of the focusing cavity; it is sufficient to ensure that the inner wall of the focusing cavity has light reflection or refraction properties. For example, using an opaque material to prepare the focusing cavity, or using an opaque material to prepare the inner wall of the focusing cavity, can achieve the effect of focusing the light scattered by the first focusing part.

[0015] Furthermore, the circumferential edge of the first light-concentrating part is disposed on the outer surface of the lampshade.

[0016] Furthermore, it includes at least two cavities for forming the lampshade, the cavities including a first focusing cavity for forming the first focusing part and a second focusing cavity for forming the focusing cavity body, the second focusing cavity having an annular cross-section perpendicular to the axial direction, and the first focusing cavity and the second focusing cavity being interconnected.

[0017] The second objective of this utility model is to provide a mold for processing the protective cover of the aforementioned lamp, characterized in that it includes at least two cavities for forming the lamp cover, wherein the cavity includes a first focusing cavity for forming the first focusing part.

[0018] The third objective of this utility model is to provide a floor brush head, including the aforementioned lamp, wherein the lamp is disposed on the front side of the floor brush head, and each of the light sources is distributed along the width direction of the vacuum cleaner.

[0019] The fourth objective of this utility model is to provide a vacuum cleaner that includes at least one of the aforementioned lamps or the aforementioned floor brush heads. Attached Figure Description

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0033] Example 1:

[0034] See appendix Figure 1 and 2 As shown, this embodiment is a lamp, including a light source 1 and a protective cover 2 disposed outside the light source 1. A lampshade 21 is disposed on the protective cover 2 in front of the light source 1. The light source 1 and the lampshade 21 are arranged sequentially along a first direction. See attached drawing. Figure 2 As shown, with the target illumination direction of the lamp as indicated by arrow A in the figure, the light source 1 and the lampshade 21 are sequentially arranged along the direction indicated by arrow A, which is also the first direction. The first direction can be the direction directly in front of the light source 1 or the direction diagonally in front of it.

[0035] The lampshade 21 in this embodiment includes a first focusing part 211. The outer surface of the first focusing part 211 is bent toward the side away from the light source 1, forming a lens shape similar to a hemispherical shape. Therefore, the light emitted by the light source 1 can be focused after passing through the first focusing part 211 after being emitted along the first direction, thus making the lamp have the effect of focusing and brightening.

[0036] In some embodiments, the focal point of the first focusing part 211 is in the first direction, thus ensuring that the light emitted by the light source 1 can be focused and emitted in the first direction.

[0037] In this embodiment, there are n light sources 1, where n ≥ 1. Each light source 1 is provided with a lampshade 21, and the curvature of the outer surface of each first focusing part 211 can have ≥ 1 values. Therefore, when the lamp needs to emit light with different ranges or brightness, the first focusing parts 211 with different curvatures can be processed during the initial processing of the lampshade 21 according to actual usage requirements. Simultaneously, the radius of the first focusing part 211 can be changed, thereby achieving diverse light emission effects and creating a certain staggered distribution of light, thus facilitating the user's observation of foreign objects in front of the lamp. Since the lampshade 21 is mounted on the protective cover 2, and the first focusing parts 211 are located on the protective cover 2, it is convenient to process or install first focusing parts 211 with various curvatures.

[0038] In some embodiments, the lampshade 21 can be integrally formed with the protective cover 2. Therefore, during the processing of the protective cover 2, the protective cover 2 with the structure of the lampshade 21 of this application can be manufactured, eliminating the need to separately attach a lens-shaped focusing structure to the surface of the light source 1 before placing the protective cover 2 outside the light source 1 with the focusing structure attached. This reduces both the steps of processing the focusing structures of each light source 1 individually and the steps of attaching the focusing structure to the surface of the light source 1. Regarding the integrally formed connection of the lampshade 21 and the protective cover 2, when the protective cover 2 is formed by injection molding, a first focusing cavity 31 for the lampshade 21 corresponding to the first light source 1 is reserved in the area of ​​the mold 3 (see Appendix). Figure 7 In the area corresponding to the lampshade 21 of the second light source 1, a first focusing cavity 31 of the lampshade 21 is reserved. It is only necessary to set the two first focusing cavities 31 to the shapes of the first focusing parts 211 corresponding to different curvatures, and the injection molding process of the protective cover 2 is not complicated. Furthermore, if the focusing structure is attached to the surface of the light source 1 and then the protective cover 2 is mounted on the outside of the light source 1, in order to avoid the overlap of the protective cover 2 and the focusing structure on the emitted light directly facing the light source 1, which would weaken the brightness and intensity of the beam, the area of ​​the protective cover 2 corresponding to the light source 1 is usually not equipped with a cover structure, but only a receiving hole for the protruding focusing structure is reserved. Therefore, the gap between the focusing structure and the receiving hole easily allows dust to enter the lamp, affecting the lamp's lifespan. In this embodiment, the protective cover 2 located at the connecting edge of the lampshade 21 does not form a gap, thus ensuring sufficient isolation between the light source 1 and the external environment, effectively reducing dust entry into the lamp.

[0039] In other possible implementations, the lampshade 21 may also be a separate part of the protective cover 2. In this case, mounting holes for mounting the lampshade 21 are formed in the area of ​​the protective cover 2 corresponding to the area where the lampshade 21 is mounted, and then the protective cover 2 is mounted at the mounting holes. This method facilitates flexible installation or more flexible replacement of the lampshade 21, thus satisfying more diverse focusing effects on the light source 1.

[0040] In some embodiments, the distance d between any light source 1 and its corresponding lampshade 21 is defined as d, and the number of values ​​for d is ≥1. This allows the light emitted through the lampshade 21 to have different ranges or beam focusing effects, satisfying more diverse application requirements for different emitted beams. In some embodiments, the light source 1 can be positioned in contact with the lampshade 21, that is, the light source 1 is in contact with the inner surface of the lampshade 21, ensuring that the light emitted by the light source 1 fully enters the lampshade 21 and is focused and brightened.

[0041] However, simply placing a lens in front of the light source 1 is insufficient to achieve adequate light focusing, resulting in a short beam range and insufficient brightness. Therefore, in some embodiments, the lamp of this invention further includes a second focusing section 212. The second focusing section 212 has a focusing cavity 2121 extending along a first direction. The first focusing section 211 is located at the end of the focusing cavity 2121 near the light source 1, and the circumferential edge of the first focusing section 211 is connected to the inner wall of the focusing cavity 2121 of the second focusing section 212. Thus, by providing the focusing cavity 2121, scattered light that is not fully focused after passing through the first focusing section 211 is reflected after illuminating the inner wall of the focusing cavity 2121, forming a beam that converges along the central axis of the focusing cavity 2121. Thus, the light beam focused by the first focusing part 211 is further focused and becomes a brighter light beam under the action of the second focusing part 212.

[0042] In some embodiments, the focal point of the first focusing section 211 is on the axial center line of the second focusing section 212. Therefore, it is possible to ensure that the light source 1 can form an effect with a longer range and higher brightness after reflection through the focusing cavity 2121.

[0043] In some embodiments, the length of the focusing cavity 2121 is greater than 0, and the circumferential edge of the second focusing part 212 is disposed on the inner wall of the focusing cavity 2121. Therefore, the first focusing part 211 can be formed inside the focusing cavity 2121. Consequently, scattered light that still exists after refraction by the first focusing part 211 can be reflected by the inner wall of the focusing cavity 2121 and continuously focused towards the axial centerline of the focusing cavity 2121, thereby achieving the effect of beam focusing. The greater the distance between the first focusing part 211 and the end of the focusing cavity 2121 furthest from the light source 1, the better the light focusing effect.

[0044] In some embodiments, the first focusing portion 211 is located within the focusing cavity 2121. That is, the distance between the circumferential edge of the first focusing portion 211 and the end of the focusing cavity 2121 furthest from the light source 1 is greater than 0. Therefore, the focusing cavity 2121 can sufficiently focus the light scattered by the first focusing portion 211 and concentrate it from the end of the focusing cavity 2121 furthest from the light source 1. In some embodiments, the entire protruding lens-shaped structural surface of the first focusing portion 211 is located within the focusing cavity 2121. Therefore, the focusing cavity can sufficiently reflect the scattered light refracted by the first focusing portion 211, thereby enabling the lamp as a whole to form a beam with a longer illumination distance and higher brightness.

[0045] In some embodiments, at least the inner wall of the focusing cavity 2121 is made of a material with reflective properties. This does not mean that a special reflective coating or other material needs to be applied to the inner wall of the focusing cavity 2121; it is sufficient to ensure that the inner wall of the focusing cavity 2121 has light-reflective properties. For example, using an opaque material to fabricate the focusing cavity 2121, or using an opaque material for the inner wall of the focusing cavity 2121, can achieve the effect of reflecting the light scattered by the first focusing part 211 and continuously focusing the light beam along its central axis.

[0046] Example 2:

[0047] See appendix Figure 3 and 4 As shown, this embodiment is a lamp fixture. The difference between this embodiment and Embodiment 1 is that this embodiment does not have a focusing cavity; instead, the circumferential edge of the first focusing part 211 is disposed on the outer surface of the lampshade 21. Thus, the first focusing part 211 is shaped to protrude from the surface of the lampshade 21 on the side away from the light source 1. In some embodiments, the effect of focusing and brightening is achieved by directly forming a hemispherical lens structure protruding away from the light source on the outer surface of the lampshade 21.

[0048] Example 3:

[0049] This embodiment is a floor brush head 4, which includes at least one lamp as described in Embodiment 1 or Embodiment 2, and also includes a back plate. The light source 1 is disposed on the back plate, and the lamp is disposed on the front side of the floor brush head 4. Each light source 1 of the lamp is a green lamp, which can have a better illumination effect on the dust on the ground, making the dust bright and easy for the user to see clearly.

[0050] See appendix Figure 5 The image shows the case where the lamp installed on the floor brush head 4 is the lamp of Embodiment 1. In this case, because the lampshade 21 has a focusing cavity 2121 structure, the light emitted from the light source 1 is more concentrated by the combined action of the first focusing part 211 and the second focusing part 212. Thus, the light can be emitted through the end of the focusing cavity 2121 away from the light source 1. When using the same light source 1, the light from this embodiment is more concentrated and has a longer range. The single beam emitted by the floor brush head 4 of this application has higher brightness, so that the illumination area in front of the floor brush head no longer presents a patchy illumination effect, but forms several very bright beams (see Appendix). Figure 10 This allows users to easily observe tiny dust particles on the surface to be cleaned. In some embodiments, the emitted light can be adjusted in various ways by changing the curvature of the outer surface of the first focusing part 211, the relative position of the adjuster in the focusing cavity 2121, or the diameter of the first focusing part 211. This allows for differentiation of the light's range and variation of the beam diameter. Therefore, it can meet the diverse requirements of different real-world applications for adjusting the emission state of the light source.

[0051] See appendix Figure 6 The image shows the case where the lamp mounted on the brush head 4 is the lamp of Embodiment 2. In this case, since the first focusing part 211 is formed on the lampshade 21, the first focusing part 211 can be processed simultaneously when processing the lampshade 21. Since the lampshade 21 is outside the light source, it is convenient to set or adjust the first focusing part 211. Furthermore, by setting the first focusing part 211 and the lampshade 21 as an integral connection (note that this includes both a structural component in which the first focusing part 211 and the lampshade 21 are set as a whole (such as integral injection molding); and a structural component in which the first focusing part 211 and the lampshade 21 are separate parts, but since the first focusing part 211 is located on the outer surface of the lampshade 21, it is convenient to set or adjust the first focusing part 211), no gap is formed at the connection between the two, thus ensuring sufficient isolation between the light source 1 and the external environment and effectively reducing dust from entering the lamp.

[0052] Example 4:

[0053] This embodiment is a vacuum cleaner, including at least one lamp of embodiment one or embodiment two or a floor brush head 4 of embodiment three.

[0054] Example 5:

[0055] See appendix Figure 7 As shown, this embodiment is a mold 3 for processing the protective cover 2 of the lamp in Embodiment 1. It includes at least two cavities for forming the lamp cover 21. The cavity includes a first focusing cavity 31 for forming a first focusing part 211, a second focusing cavity 32 for forming a focusing cavity body 2121, and a main cavity 33 for forming the main body of the protective cover 2. The second focusing cavity 32 is outside the main cavity 33. The first focusing cavity 31 is connected to the main cavity 33. The cross-section of the second focusing cavity 32 perpendicular to its axial direction is annular. The first focusing cavity 31 and the second focusing cavity 32 are connected to each other.

[0056] For other possible implementations, see Appendix Figure 8 As shown, the mold 3 used for processing the lamps of Embodiment 2 does not include the second focusing cavity, but only includes the first focusing cavity 31 for forming the first focusing part 211, and the first focusing cavity 31 is set at the front end of the main cavity 33 for forming the main body of the protective cover 2.

[0057] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
