Description

Technical Field

[0001] The utility model relates to the technical field of purifiers, and in particular to a purifier. Background Art

[0002] At present, in the relevant technology, the purifier displays the environmental information around the purifier through lighting effects. For example, when there is a lot of dust in the environment around the purifier, the light will show red, and when there is less dust in the environment around the purifier, the light will show green. However, since the light is directly emitted into the environment around the purifier through the lamp beads, the lighting effect is relatively dazzling, affecting user use. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] To this end, a first aspect of the present invention provides a purifier.

[0005] In view of this, the first aspect of the present invention provides a purifier, including a shell, a circuit board assembly, a reflective component and a light-guiding component; the shell includes a mounting portion, the circuit board assembly includes a circuit board and a first lamp bead, the circuit board is arranged on the mounting portion, the first lamp bead is arranged on the circuit board, the reflective component is annular and arranged around the first lamp bead, the light-guiding component is arranged on the outside of the first lamp bead, and the light-guiding component is provided with a first reflecting surface; the light emitted by the first lamp bead can be irradiated to the first reflecting surface, and the first reflecting surface can reflect the light to the reflective component.

[0006] The present application provides a purifier that can purify ambient air and improve the air quality in the environment. The purifier includes a housing, a circuit board assembly, a reflective component and a light-guiding component. The housing includes a mounting portion, and the provision of the mounting portion can reduce the difficulty of assembling the circuit board in the housing. The circuit board assembly includes a circuit board and a first lamp bead. The circuit board is arranged in the mounting portion, and the first lamp bead is arranged on the circuit board. The circuit board can power and drive the first lamp bead. The reflective component is annular and arranged around the first lamp bead. The light-guiding component is arranged on the outside of the first lamp bead. The light-guiding component is provided with a first reflecting surface. When the purifier is working, the light emitted by the first lamp bead can be irradiated to the first reflecting surface, and the first reflecting surface can reflect the light to the reflective component. The light is then reflected into the surrounding environment by the reflective component, which can prevent the light from directly entering the environment, making the light softer, avoiding the light effect from being too glaring, and facilitating user use. The light reflected by the light-guiding component and the reflective component can further enhance the lighting effect. While ensuring the brightness of the light, it can prevent the light from affecting the user's observation, thereby improving the product performance of the purifier.

[0007] By providing a light-guiding component, the internal structure of the purifier can be simplified, and an additional reflecting device is no longer required. This reduces costs, simplifies the installation steps in the purifier, and reduces the difficulty of installation.

[0008] Furthermore, by placing the first lamp bead on the circuit board, and placing the circuit board on the mounting portion, an integrated circuit board assembly design can be achieved, which can simplify assembly and improve the assembly efficiency of the purifier. Providing a first reflective surface on the light guide component can also improve the reflection efficiency of light.

[0009] In addition, the purifier in the above technical solution provided by the present invention may also have the following additional technical features:

[0010] In some technical solutions of the present invention, optionally, the first reflecting surface is located on the side of the light-guiding component close to the first lamp bead; and extends obliquely from the side of the first reflecting surface close to the first lamp bead to the side of the first reflecting surface close to the reflective component relative to the axial direction of the light-guiding component.

[0011] In this technical solution, the first reflective surface is located on the side of the light guide component closest to the first lamp bead, facilitating incident light striking the first reflective surface and improving light reflection efficiency. The first reflective surface extends at an angle relative to the axial direction of the light guide component from the side closest to the first lamp bead to the side closest to the reflective component, facilitating light reflection. The angled first reflective surface reflects light from the first lamp bead toward the reflective component, preventing it from directly radiating into the surrounding environment. This softens the light, avoids glare, and improves user experience.

[0012] In some technical solutions of the present invention, optionally, in the axial direction of the reflective component, the light-guiding component and the reflective component at least partially overlap, and there is a gap between the light-guiding component and the reflective component.

[0013] In this technical solution, the light-guiding component and the reflective component at least partially overlap in the axial direction of the reflective component, which can avoid the presence of a gap between the light-guiding component and the reflective component in the axial direction of the reflective component, thereby preventing the light generated by the first lamp bead from directly irradiating the surrounding environment. The light is reflected before irradiating the environment, making the light softer, avoiding excessive glare, and facilitating user use. There is a gap between the light-guiding component and the reflective component. Since the light generated by the first lamp bead will irradiate the light-guiding component and then be reflected by the first reflective surface of the light-guiding component to the reflective component, the gap between the light-guiding component and the reflective component can facilitate the propagation of light between the light-guiding component and the reflective component, ensuring the brightness of the light while preventing the light from affecting the user's observation, thereby improving the product performance of the purifier.

[0014] In some technical solutions of the present invention, optionally, the purifier also includes a light-transmitting component, the light-transmitting component includes a first light-transmitting surface and a second light-transmitting surface, the first light-transmitting surface faces the first lamp bead, and the second light-transmitting surface faces the reflective component; wherein, the light emitted by the first lamp bead can enter the light-transmitting component through the first light-transmitting surface and illuminate the first reflective surface, the first reflective surface can reflect the light to the second light-transmitting surface, and illuminate the reflective component through the second light-transmitting surface.

[0015] In this technical solution, the purifier also includes a light-transmitting component, which includes a first light-transmitting surface and a second light-transmitting surface. The first light-transmitting surface faces the first lamp bead, and the second light-transmitting surface faces the reflective component. The light emitted by the first lamp bead can enter the light-transmitting component through the first light-transmitting surface and illuminate the first reflective surface. The first reflective surface can reflect the light to the second light-transmitting surface, and then illuminate the reflective component through the second light-transmitting surface. The light is then reflected by the reflective component into the surrounding environment of the purifier, transmitted to the first reflective surface via the light-transmitting component, and then reflected by the reflective component into the environment. This can enhance the lighting effect of the purifier, avoid direct light exposure to the environment, make the light softer, and avoid excessive glare, making it easier for users to use.

[0016] In some technical solutions of the present invention, optionally, the reflective component extends obliquely from the inner peripheral edge to the outer peripheral edge in a direction away from the housing.

[0017] In this technical solution, the reflective component extends obliquely from the inner edge to the outer edge in the direction away from the shell, that is, the wall surface used for reflecting light in the reflective component can be inclined toward the center of the reflective component. When the light passes through the second light-transmitting surface and shines on the reflective component, the obliquely extended reflective component can converge the light, which can prevent the light from directly irradiating the surrounding environment, and also improve the brightness of the light.

[0018] In some technical solutions of the present invention, optionally, the light-transmitting component includes a body, the body extends in a ring shape, a groove is provided on one side of the body close to the circuit board, the notch of the groove faces the first lamp bead, and the inner wall of the groove is the first light-transmitting surface.

[0019] In this technical solution, the light-transmitting component includes a body extending in an annular shape. A groove is provided on a side of the body proximal to the circuit board. Since the opening of the groove faces the first lamp bead, light generated by the first lamp bead passes through the opening of the groove and is irradiated onto the first light-transmitting surface. The inner wall of the groove serves as the first light-transmitting surface, simplifying the structure of the light-transmitting component and reducing installation difficulty. By arranging the opening of the groove toward the first lamp bead, light is facilitated to enter the light-transmitting component, thereby facilitating light transmission within the light-transmitting component.

[0020] In some technical solutions of the present invention, optionally, the reflective component rests against the side of the main body away from the circuit board, and the translucent component also includes a translucent portion, which is connected to the main body, located on the side of the main body away from the circuit board, and arranged along the inner periphery of the reflective component, and the circumferential outer side wall of the translucent portion is a second translucent surface.

[0021] In this technical solution, the reflective component is against the side of the body away from the circuit board. Since the first lamp bead is provided on the circuit board, by arranging the reflective component on the side of the body away from the circuit board, the light emitted by the first lamp bead will pass through the light-transmitting component and then be reflected by the reflective component into the surrounding environment. Since the light-transmitting component also includes a light-transmitting portion, the light-transmitting portion is connected to the body, located on the side of the body away from the circuit board, and arranged along the inner periphery of the reflective component, and the circumferential outer wall of the light-transmitting portion is a second light-transmitting surface, the light entering the light-transmitting component from the first lamp bead will be transmitted to the reflective component by the second light-transmitting surface of the outer wall of the light-transmitting portion, and then reflected to the surrounding environment of the purifier by the reflective component, which can prevent the light from directly entering the environment, making the light softer, avoiding the lighting effect from being too glaring, and convenient for users to use.

[0022] In some technical solutions of the present invention, optionally, the purifier also includes a second lamp bead and a cover body, the second lamp bead is arranged on the circuit board, the cover body is arranged on the side of the light-transmitting component away from the circuit board, the light-guiding component is provided with a light-transmitting hole, the light-transmitting hole is opposite to the second lamp bead, and the light generated by the second lamp bead passes through the light-transmitting hole and the cover body to irradiate the outside of the cover body.

[0023] In this technical solution, the purifier further includes a second lamp bead and a cover. The second lamp bead is disposed on the circuit board, and the cover is disposed on the first side of the light-transmitting component away from the circuit board. The light-guiding component is provided with a light-transmitting hole, which is opposite to the second lamp bead. The light generated by the second lamp bead passes through the light-transmitting hole and the cover to the outside of the cover. When the second lamp bead is in operation, the light will pass through the cover and enter the surrounding environment. At the same time, the cover, which is located on the first side of the light-transmitting component away from the circuit board, can protect the second lamp bead. At the same time, after the second lamp bead emits light, it will form a prompt message. The light of the second lamp bead will transmit the information to the user through the cover. The user can judge the operating status of the purifier based on the light pattern generated by the second lamp bead.

[0024] Furthermore, since multiple second lamp beads are provided on the circuit board, the circuit board can control a part of the multiple second lamp beads to emit light, and the other part is in an off state. Among them, the luminous second lamp beads can be arranged and combined into the real-time working parameters of the purifier, which is convenient for the user to judge the working status of the purifier according to the working parameters prompted on the cover.

[0025] By arranging the first lamp bead on the circuit board and arranging the circuit board on the mounting portion, an integrated design of the circuit board assembly can be achieved, which can simplify the assembly difficulty and improve the assembly efficiency of the purifier.

[0026] By arranging the first and second lamp beads to cooperate with each other to emit light, the appearance of the purifier can be improved. The circuit board controlling the first and second lamp beads to emit light can also serve as a prompt, making it easier for the user to understand the working progress or working status of the purifier.

[0027] The ring-shaped reflective component can expand the reflection range and make the purifier evenly reflect the light source to the surrounding environment.

[0028] In some technical solutions of the present invention, optionally, the ratio of the diameter of the cover body to the diameter of the outer edge of the reflective component is greater than or equal to 0.2 and less than or equal to 0.8.

[0029] In this technical solution, the ratio of the diameter of the cover body to the diameter of the outer edge of the reflective component is greater than or equal to 0.2 and less than or equal to 0.8. By limiting the ratio of the diameter of the cover body to the diameter of the outer edge of the reflective component, the proportional coordination of the reflective component and the cover body can be improved. Since the cover body is arranged on the outside of the second lamp bead, and the second lamp bead can combine display parameters, by improving the coordination of the proportions of the reflective component and the cover body, the light reflected by the reflective component can be prevented from affecting the prompt light on the cover body, which is convenient for users to observe and avoid glare. Limiting the ratio of the diameter of the cover body to the diameter of the outer edge of the reflective component can also improve the overall lighting effect of the purifier, making the light softer and making it easier for users to observe the display light on the cover body, that is, the light emitted by the second lamp bead.

[0030] In some technical solutions of the present invention, optionally, the ratio of the distance between the center of the cover body and the top wall of the shell to the diameter of the outer edge of the reflective component is greater than or equal to 0.1 and less than or equal to 0.7.

[0031] In this technical solution, the ratio of the distance between the center of the cover and the top wall of the housing to the diameter of the outer edge of the reflective component is greater than or equal to 0.1 and less than or equal to 0.7. By limiting the ratio of the distance between the center of the cover and the top wall of the housing to the diameter of the outer edge of the reflective component, the position of the reflective component can be more coordinated with the height of the purifier, improving the neatness of the purifier's appearance. At the same time, it further prevents light reflected by the reflective component from affecting the warning light on the cover, making it easier for users to observe and avoiding glare.

[0032] Specifically, the distance between the center of the cover body and the top wall of the housing is L1, and the diameter of the outer edge of the reflective component is R2.

[0033] Specifically, the ratio of the distance L1 between the center of the cover body and the top wall of the shell to the diameter R2 of the outer edge of the reflective component is 0.1, the ratio of the distance L1 between the center of the cover body and the top wall of the shell to the diameter R2 of the outer edge of the reflective component is 0.2, the ratio of the distance L1 between the center of the cover body and the top wall of the shell to the diameter R2 of the outer edge of the reflective component is 0.4, and the ratio of the distance L1 between the center of the cover body and the top wall of the shell to the diameter R2 of the outer edge of the reflective component is 0.7.

[0034] In some technical solutions of the present invention, optionally, the ratio of the diameter of the outer edge of the reflective component to the width of the shell is greater than or equal to 0.2 and less than or equal to 0.8.

[0035] In this technical solution, the ratio of the outer diameter of the reflective component to the width of the housing is greater than or equal to 0.2 and less than or equal to 0.8. By limiting the ratio of the outer diameter of the reflective component to the width of the housing, the installation position of the reflective component can be more coordinated across the width of the purifier, improving the neatness of the purifier's appearance.

[0036] Specifically, the ratio of the diameter R2 of the outer edge of the reflecting component to the width L2 of the shell can be 0.2, the ratio of the diameter R2 of the outer edge of the reflecting component to the width L2 of the shell can be 0.4, the ratio of the diameter R2 of the outer edge of the reflecting component to the width L2 of the shell can be 0.6, and the ratio of the diameter R2 of the outer edge of the reflecting component to the width L2 of the shell can be 0.8.

[0037] In some technical solutions of the present invention, optionally, the angle between the reflective component and the top wall of the shell is greater than or equal to 60 degrees and less than or equal to 85 degrees.

[0038] In this technical solution, the angle between the reflective component and the top wall of the housing is greater than or equal to 60 degrees and less than or equal to 85 degrees. Because light is irradiated by the second light-transmitting surface to the reflective component, which then reflects the light to the surrounding environment of the purifier, limiting the angle between the reflective component and the top wall of the housing can prevent the light from being too concentrated or too divergent, thereby improving the brightness of the light while ensuring softness.

[0039] Specifically, the included angle between the reflective component and the top wall of the housing is α.

[0040] Specifically, the angle α between the reflective component and the top wall of the housing is greater than or equal to 60 degrees and less than or equal to 85 degrees. The angle α between the reflective component and the top wall of the housing may be 60 degrees, the angle α between the reflective component and the top wall of the housing may be 65 degrees, the angle α between the reflective component and the top wall of the housing may be 70 degrees, the angle α between the reflective component and the top wall of the housing may be 75 degrees, and the angle α between the reflective component and the top wall of the housing may be 85 degrees.

[0041] Among them, when the angle α between the reflective component and the top wall of the shell is 75 degrees, the light irradiated to the surrounding environment through the reflective component has a better effect, which can make the light more flexible and avoid the degree of light convergence being too large or too small, making it easier for users to use.

[0042] In some technical solutions of the present invention, optionally, the side wall of the shell is provided with an air inlet, the top wall of the shell is provided with an air outlet, the inside of the shell has an air duct, and the air inlet is connected to the air outlet through the air duct; the circuit board is provided on the side wall of the shell, located on the side of the air inlet close to the air outlet.

[0043] In this technical solution, the side wall of the shell is provided with an air inlet, and the top wall of the shell is provided with an air outlet. By providing the air inlet and the air outlet, the circulation of gas in the purifier shell can be achieved. The gas enters through the air inlet, is filtered and purified, and then discharged through the air outlet, thereby achieving circulation and purification of the ambient air. The shell is provided with an air duct, and the air inlet is connected to the air outlet through the air duct, which can improve the airflow guidance efficiency and thus improve the purification efficiency. The circuit board is arranged on the side wall of the shell, which can reduce the obstruction of the circuit board to the airflow in the air duct, and reduce the impact of the circuit board on the airflow while facilitating the installation of the circuit board. The circuit board is located on the side of the air inlet close to the air outlet. The airflow flowing in the air duct can dissipate heat for the circuit board, reduce the operating temperature of the circuit board, thereby extending the service life of the circuit board and preventing the circuit board from being damaged by high temperature.

[0044] In some technical solutions of the present invention, optionally, the purifier also includes an air outlet grille, which is arranged in the air duct and located on the side of the air duct close to the air outlet. An air guide surface is provided on the inner wall of the air outlet grille close to the circuit board, and the air guide surface extends upward from the side close to the circuit board to the side close to the center of the air duct at an angle relative to the height direction of the shell.

[0045] In this technical solution, the purifier also includes an air outlet grille, which is arranged in the air duct and is located on the side of the air duct close to the air outlet. The inner wall of the air outlet grille is provided with an air guide surface on the side close to the circuit board. The air guide surface helps the flow of air. At the same time, the air guide surface extends upward from the side close to the circuit board to the side close to the center of the air duct at an angle relative to the height direction of the shell, which can reserve space for the installation of the circuit board and reflective components, reduce the wind resistance in the air duct, and further reduce the impact of the circuit board on the air duct. The air outlet grille can also prevent foreign matter from entering and play a role in protecting the purifier. The provision of the air guide surface can also reduce the impact of the circuit board on the flow of purified air while ensuring the stable installation of the circuit board, thereby improving the purification efficiency of the purifier.

[0046] In some technical solutions of the present invention, optionally, the angle between the air guide surface and the height direction of the shell is greater than or equal to 120 degrees and less than or equal to 150 degrees.

[0047] In this technical solution, the angle between the air guide surface and the height direction of the housing is greater than or equal to 120 degrees and less than or equal to 150 degrees. Setting the angle between the air guide surface and the height direction of the housing between 120 and 150 degrees can guide the airflow and prevent the airflow velocity from being affected by the circuit board. At the same time, by limiting the angle between the air guide surface and the height direction of the housing, the flow path of the airflow can be optimized and the purification efficiency can be improved.

[0048] Specifically, the included angle β between the air guide surface and the height direction of the shell is greater than or equal to 120 degrees and less than or equal to 150 degrees.

[0049] Specifically, the angle β between the wind guide surface and the height direction of the shell can be 120 degrees, the angle β between the wind guide surface and the height direction of the shell can be 130 degrees, the angle β between the wind guide surface and the height direction of the shell can be 140 degrees, and the angle β between the wind guide surface and the height direction of the shell can be 150 degrees.

DETAILED DESCRIPTION

[0066] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0067] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0068] Refer to the following Figures 1 to 12 A purifier according to some embodiments of the present invention is described.

[0069] like Figure 1 and Figure 2 As shown, in an embodiment of the present invention, a purifier 100 is provided, including a shell 110, a circuit board assembly 120, a reflective component 130 and a light-guiding component 136; the shell 110 includes a mounting portion 112, the circuit board assembly 120 includes a circuit board 122 and a first lamp bead 124, the circuit board 122 is arranged on the mounting portion 112, the first lamp bead 124 is arranged on the circuit board 122, the reflective component 130 is annular and arranged around the first lamp bead 124, the light-guiding component 136 is arranged on the outside of the first lamp bead 124, and the light-guiding component 136 is provided with a first reflecting surface 138; the light emitted by the first lamp bead 124 can be irradiated to the first reflecting surface 138, and the first reflecting surface 138 can reflect the light to the reflective component 130.

[0070] The present application provides a purifier 100 that can purify ambient air and improve the air quality in the environment. The purifier 100 includes a housing 110, a circuit board assembly 120, a reflective component 130 and a light-guiding component 136. The housing 110 includes a mounting portion 112. The provision of the mounting portion 112 can reduce the difficulty of assembling the circuit board 122 in the housing 110. The circuit board assembly 120 includes a circuit board 122 and a first lamp bead 124. The circuit board 122 is provided on the mounting portion 112. The first lamp bead 124 is provided on the circuit board 122. The circuit board 122 can power and drive the first lamp bead 124. The reflective component 130 is annular and arranged around the first lamp bead 124. The light-guiding component 136 is provided on the outside of the first lamp bead 124. The light-guiding component 136 is provided with a first reflective surface 138. When the purifier 100 is working, the light emitted by the first lamp bead 124 can be irradiated to the first reflective surface 138, and the first reflective surface 138 can reflect the light to the reflective component 130. The light is then reflected by the reflective component 130 into the surrounding environment, preventing direct light from entering the environment, making the light softer and avoiding excessive glare, making it easier for users to use. The light reflected by the light guide component 136 and the reflective component 130 can further enhance the lighting effect, while ensuring light brightness while preventing light from affecting user observation, thereby improving the product performance of the purifier 100.

[0071] By providing the light guide component 136 , the structure inside the purifier 100 can be simplified, and no additional reflecting device is required, which reduces the cost and simplifies the installation steps inside the purifier 100 and reduces the difficulty of installation.

[0072] Furthermore, by disposing the first lamp bead 124 on the circuit board 122, and disposing the circuit board 122 on the mounting portion 112, an integrated design of the circuit board assembly 120 can be achieved, which can simplify assembly and improve the assembly efficiency of the purifier 100. Providing a first reflective surface 138 on the light guide component 136 can also improve the reflection efficiency of light.

[0073] In the height direction of the shell 110, the setting height of the light guide component 136 is higher than the setting height of the first lamp bead 124. All the light emitted by the first lamp bead 124 in the horizontal direction can be irradiated on the light guide component 136, which can prevent the light from directly emitting from the purifier 100 and improve the flexibility of the light.

[0074] Specifically, if Figure 2 As shown, the height direction of the housing 110 is the direction indicated by F1.

[0075] Specifically, there can be multiple first lamp beads 124, which are arranged in a ring. The light guide component 136 can also be arranged in a ring, and the radius of the light band formed by the first lamp beads 124 is smaller than the radius of the light guide component 136. This can further improve the reflection efficiency of light and prevent light from directly reaching the surrounding environment of the purifier 100.

[0076] Specifically, the projection of the first lamp bead 124 in the axial direction of the light guide component 136 is located inside the light guide component 136 .

[0077] Specifically, if Figure 1 As shown, a panel 133 can be provided on the housing 110 to protect the interior of the purifier 100 and prevent external contaminants from contaminating the circuit board assembly 120. The provision of the panel 133 also facilitates the installation of the light guide component 136 and the reflective component 130, thereby improving the assembly efficiency of the purifier 100.

[0078] Specifically, if Figure 6 As shown, there are multiple first lamp beads 124, and the multiple first lamp beads 124 are arranged in a ring shape, which is the same shape as the light-transmitting component 140, and can improve the light guiding effect.

[0079] Specifically, if Figure 5 As shown, the height direction of the shell 110 is the direction shown by F1; the top wall 119 of the shell 110 extends along the width direction of the shell 110, so the direction of the top wall 119 of the shell 110 is the direction shown by F2.

[0080] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0081] The first reflective surface 138 is located on a side of the light guide component 136 close to the first lamp bead 124 ; it extends obliquely relative to the axial direction of the light guide component 136 from the side of the first reflective surface 138 close to the first lamp bead 124 to the side of the first reflective surface 138 close to the reflective component 130 .

[0082] In this embodiment, the first reflective surface 138 is located on the side of the light-guiding component 136 near the first lamp bead 124, facilitating incident light from being irradiated by the first reflective surface 138 and improving light reflection efficiency. The first reflective surface 138 extends obliquely relative to the axial direction of the light-guiding component 136 from the side near the first lamp bead 124 to the side near the reflective component 130, facilitating light reflection. The inclined first reflective surface 138 reflects light emitted by the first lamp bead 124 toward the reflective component 130, preventing the light from directly irradiating the environment, resulting in a softer light and less glaring lighting effect, making it easier for users to use.

[0083] Specifically, if Figure 3 As shown, the axial direction of the light guide member 136 is the F5 direction. This embodiment provides a purifier 100. In addition to the technical features of the above embodiment, this embodiment further includes the following technical features.

[0084] In the axial direction of the light reflecting member 130 , the light guiding member 136 at least partially overlaps with the light reflecting member 130 , and a gap 139 is defined between the light guiding member 136 and the light reflecting member 130 .

[0085] In this embodiment, the light guide component 136 and the reflective component 130 at least partially overlap in the axial direction of the reflective component 130, thereby preventing a gap between the light guide component 136 and the reflective component 130 in the axial direction of the reflective component 130, thereby preventing the light generated by the first lamp bead 124 from directly irradiating the surrounding environment. The light is reflected before irradiating the environment, making the light softer, avoiding excessive glare, and facilitating user use. A gap 139 is provided between the light guide component 136 and the reflective component 130. Since the light generated by the first lamp bead 124 will irradiate the light guide component 136 and then be reflected by the first reflective surface 138 of the light guide component 136 to the reflective component 130, the gap 139 provided between the light guide component 136 and the reflective component 130 can facilitate the propagation of light between the light guide component 136 and the reflective component 130, thereby ensuring the brightness of the light while preventing the light from affecting the user's observation, thereby improving the product performance of the purifier 100.

[0086] Among them, such as Figure 3 As shown, after the light is emitted by the first lamp bead 124, it irradiates the light guide component 136 along the direction d1, and is then reflected by the first reflecting surface 138 of the light guide component 136 along the direction d2 to the reflective component 130. Finally, the light is reflected by the reflective component 130 into the surrounding environment along the direction d3.

[0087] Specifically, the axial direction of the reflective member 130 is the F5 direction.

[0088] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0089] The purifier 100 also includes a light-transmitting component 140, which includes a first light-transmitting surface 142 and a second light-transmitting surface 144. The first light-transmitting surface 142 faces the first lamp bead 124, and the second light-transmitting surface 144 faces the reflective component 130. The light emitted by the first lamp bead 124 can enter the light-transmitting component 140 through the first light-transmitting surface 142 and illuminate the first reflective surface 138. The first reflective surface 138 can reflect the light to the second light-transmitting surface 144 and illuminate the reflective component 130 through the second light-transmitting surface 144.

[0090] In this embodiment, the purifier 100 further includes a light-transmitting component 140, which includes a first light-transmitting surface 142 and a second light-transmitting surface 144. The first light-transmitting surface 142 faces the first lamp bead 124, and the second light-transmitting surface 144 faces the reflective component 130. Light emitted by the first lamp bead 124 can enter the light-transmitting component 140 through the first light-transmitting surface 142 and illuminate the first reflective surface 138. The first reflective surface 138 can reflect the light to the second light-transmitting surface 144, and then illuminate the reflective component 130 through the second light-transmitting surface 144. The light is then reflected by the reflective component 130 into the surrounding environment of the purifier 100, transmitted to the first reflective surface 138 via the light-transmitting component 140, and then reflected into the environment by the reflective component 130. This can enhance the lighting effect of the purifier 100, prevent the light from directly irradiating the environment, make the light softer, and avoid excessive glare, making it easier for users to use.

[0091] Among them, such as Figure 4 As shown, the light emitted by the first lamp bead 124 can enter the light-transmitting component 140 along the direction d4 and illuminate the first reflecting surface 138. The first reflecting surface 138 can reflect the light along the direction d5 to the reflective component 130, and then reflect the light along the direction d6 to the surrounding environment of the purifier 100 through the reflective component 130.

[0092] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0093] The reflective component 130 extends obliquely from the inner peripheral edge to the outer peripheral edge in a direction away from the housing 110 .

[0094] In this embodiment, the reflective component 130 extends obliquely from the inner edge to the outer edge in a direction away from the shell 110, that is, the wall surface used for reflecting light in the reflective component 130 can be inclined toward the center of the reflective component 130. When the light passes through the second light-transmitting surface 144 and shines on the reflective component 130, the obliquely extended reflective component 130 can converge the light, thereby preventing the light from directly irradiating the surrounding environment and also improving the brightness of the light.

[0095] Specifically, the reflective component 130 may be a disk, and the disk may extend in a conical shape, so that the reflective wall surface of the reflective component 130 may be inclined toward the center of the reflective component 130, thereby improving the reflection efficiency of light.

[0096] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0097] like Figure 7 、 Figure 8 and Figure 9 As shown, the light-transmitting component 140 includes a body 145 , which extends in a ring shape. A groove 146 is provided on one side of the body 145 close to the circuit board 122 . The notch of the groove 146 faces the first lamp bead 124 , and the inner wall of the groove 146 is the first light-transmitting surface 142 .

[0098] In this embodiment, the light-transmitting component 140 includes a body 145 extending in an annular shape. A groove 146 is provided on a side of the body 145 proximal to the circuit board 122. Since the opening of the groove 146 faces the first lamp bead 124, light generated by the first lamp bead 124 can pass through the opening of the groove 146 and illuminate the first light-transmitting surface 142. The inner wall of the groove 146 serves as the first light-transmitting surface 142, simplifying the structure of the light-transmitting component 140 and reducing installation difficulty. By arranging the opening of the groove 146 toward the first lamp bead 124, light can enter the light-transmitting component 140 more easily, thereby facilitating light transmission within the light-transmitting component 140.

[0099] Specifically, if Figure 9 As shown, the notch of the groove 146 faces the direction F3.

[0100] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0101] like Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the reflective component 130 is against the side of the main body 145 away from the circuit board 122, and the translucent component 140 also includes a translucent portion 148, which is connected to the main body 145, located on the side of the main body 145 away from the circuit board 122, and arranged along the inner periphery of the reflective component 130, and the circumferential outer side wall of the translucent portion 148 is the second translucent surface 144.

[0102] In this embodiment, the reflective component 130 is against the side of the main body 145 away from the circuit board 122. Since the first lamp bead 124 is provided on the circuit board 122, by arranging the reflective component 130 on the side of the main body 145 away from the circuit board 122, the light is emitted by the first lamp bead 124, passes through the translucent component 140, and is then reflected by the reflective component 130 into the surrounding environment. Since the light-transmitting component 140 also includes a light-transmitting portion 148, the light-transmitting portion 148 is connected to the main body 145, is located on the side of the main body 145 away from the circuit board 122, and is arranged along the inner periphery of the reflective component 130, and the circumferential outer wall of the light-transmitting portion 148 is the second light-transmitting surface 144. Therefore, the light entering the light-transmitting component 140 from the first lamp bead 124 will be transmitted to the reflective component 130 by the second light-transmitting surface 144 of the outer wall of the light-transmitting portion 148, and then reflected to the surrounding environment of the purifier 100 by the reflective component 130, which can prevent the light from directly entering the environment, making the light softer, avoiding the lighting effect from being too glaring, and convenient for users to use.

[0103] Specifically, if Figure 1 As shown, the circumferential direction of the light-transmitting portion 148 is the direction indicated by F6.

[0104] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0105] like Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the purifier 100 also includes a second lamp bead 126 and a cover body 150. The second lamp bead 126 is arranged on the circuit board 122, and the cover body 150 is arranged on the side of the light-transmitting component 140 away from the circuit board 122. The light-guiding component 136 is provided with a light-transmitting hole 137, and the light-transmitting hole 137 is opposite to the second lamp bead 126. The light generated by the second lamp bead 126 passes through the light-transmitting hole 137 and the cover body 150 to irradiate the outside of the cover body 150.

[0106] In this embodiment, the purifier 100 further includes second lamp beads 126 and a cover 150. The second lamp beads 126 are disposed on the circuit board 122. The cover 150 is disposed on a side of the light-transmitting component 140 away from the circuit board 122. The light-guiding component 136 is provided with a light-transmitting hole 137, which is opposite the second lamp beads 126. The light generated by the second lamp beads 126 passes through the light-transmitting hole 137 and the cover 150 to the outside of the cover 150, covering the plurality of second lamp beads 126. The cover 150 on the inside can protect the second lamp beads 126. At the same time, after the second lamp beads 126 emit light, a prompt message is formed. The light of the second lamp beads 126 transmits the information to the user through the cover 150. The user can judge the working status of the purifier 100 based on the light pattern generated by the second lamp beads 126.

[0107] Furthermore, since a plurality of second lamp beads 126 are provided on the circuit board 122, the circuit board 122 can control a portion of the plurality of second lamp beads 126 to emit light, while another portion is in an off state. The luminous second lamp beads 126 can be arranged and combined into real-time working parameters of the purifier 100, making it convenient for the user to judge the working status of the purifier 100 according to the working parameters prompted on the cover body 150.

[0108] By arranging multiple first lamp beads 124 and multiple second lamp beads 126 on the circuit board 122 and arranging the circuit board 122 on the mounting portion 112, an integrated design of the circuit board assembly 120 can be achieved, which can simplify assembly difficulty and improve assembly efficiency of the purifier 100.

[0109] By arranging the first lamp bead 124 and the second lamp bead 126 to cooperate with each other to emit light, the appearance of the purifier 100 can be improved. The circuit board 122 controls the first lamp bead 124 and the second lamp bead 126 to emit light, which can also serve as a reminder for the user to understand the working progress or working status of the purifier 100.

[0110] The ring-shaped reflective component 130 can expand the reflection range and make the purifier 100 evenly reflect the light source to the surrounding environment.

[0111] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0112] like Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the ratio of the diameter of the cover body 150 to the diameter of the outer edge of the reflective component 130 is greater than or equal to 0.2 and less than or equal to 0.8.

[0113] In this embodiment, the ratio of the diameter of the cover 150 to the diameter of the outer edge of the reflective component 130 is greater than or equal to 0.2 and less than or equal to 0.8. By limiting the ratio of the diameter of the cover 150 to the diameter of the outer edge of the reflective component 130, the proportional coordination of the reflective component 130 and the cover 150 can be improved. Because the cover 150 is located outside the second lamp bead 126, and the second lamp bead 126 can be combined with display parameters, by improving the proportional coordination of the reflective component 130 and the cover 150, the light reflected by the reflective component 130 can be prevented from affecting the indicator light on the cover 150, making it easier for users to observe and avoiding glare. Limiting the ratio of the diameter of the cover 150 to the diameter of the outer edge of the reflective component 130 can also improve the overall lighting effect of the purifier 100, making the light softer and easier for users to observe the indicator light on the cover 150, i.e., the light emitted by the second lamp bead 126.

[0114] Specifically, the diameter of the cover body 150 is R1, and the diameter of the outer edge of the reflective component 130 is R2.

[0115] Specifically, the ratio of the diameter R1 of the cover body 150 to the diameter R2 of the outer edge of the reflecting component 130 can be 0.2, the ratio of the diameter R1 of the cover body 150 to the diameter R2 of the outer edge of the reflecting component 130 can be 0.4, the ratio of the diameter R1 of the cover body 150 to the diameter R2 of the outer edge of the reflecting component 130 can be 0.6, and the ratio of the diameter R1 of the cover body 150 to the diameter R2 of the outer edge of the reflecting component 130 can be 0.8.

[0116] Among them, when the ratio of the diameter R1 of the cover body 150 to the diameter R2 of the outer edge of the reflective component 130 is 0.5, the light reflected by the reflective component 130 will not affect the prompt light on the cover body 150, making the light softer and easier for users to observe.

[0117] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0118] like Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the ratio of the distance between the center of the cover body 150 and the top wall 119 of the housing 110 to the diameter of the outer edge of the reflective component 130 is greater than or equal to 0.1 and less than or equal to 0.7.

[0119] In this embodiment, the ratio of the distance between the center of the cover 150 and the top wall 119 of the housing 110 to the diameter of the outer edge of the reflective component 130 is greater than or equal to 0.1 and less than or equal to 0.7. By limiting the ratio of the distance between the center of the cover 150 and the top wall 119 of the housing 110 to the diameter of the outer edge of the reflective component 130, the position of the reflective component 130 can be more coordinated with the height of the purifier 100, improving the neatness of the purifier 100's appearance. At the same time, it further prevents the light reflected by the reflective component 130 from affecting the warning light on the cover 150, making it easier for users to observe and avoiding glare.

[0120] Specifically, the center of the cover body 150 is shown as point A. Since the cover body 150 is circular, the center of the cover body 150 is the center point A of the circle.

[0121] Specifically, the distance between the center of the cover body 150 and the top wall 119 of the housing 110 is L1, and the diameter of the outer edge of the reflective component 130 is R2.

[0122] Specifically, the ratio of the distance L1 between the center of the cover body 150 and the top wall 119 of the shell 110 to the diameter R2 of the outer edge of the reflective component 130 is 0.1, the ratio of the distance L1 between the center of the cover body 150 and the top wall 119 of the shell 110 to the diameter R2 of the outer edge of the reflective component 130 is 0.2, the ratio of the distance L1 between the center of the cover body 150 and the top wall 119 of the shell 110 to the diameter R2 of the outer edge of the reflective component 130 is 0.4, and the ratio of the distance L1 between the center of the cover body 150 and the top wall 119 of the shell 110 to the diameter R2 of the outer edge of the reflective component 130 is 0.7.

[0123] Among them, when the ratio of the distance between the center of the cover body 150 and the top wall 119 of the shell 110 to the diameter of the outer edge of the reflective component 130 is 0.4, the light is more easily reflected to the surrounding environment, and the brightness of the light is softened, and the light display on the cover body 150 is more uniform and the brightness is uniform.

[0124] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0125] like Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the ratio of the diameter of the outer edge of the reflective component 130 to the width of the housing 110 is greater than or equal to 0.2 and less than or equal to 0.8.

[0126] In this embodiment, the ratio of the outer diameter of the reflective member 130 to the width of the housing 110 is greater than or equal to 0.2 and less than or equal to 0.8. By limiting the ratio of the outer diameter of the reflective member 130 to the width of the housing 110, the installation position of the reflective member 130 can be more coordinated across the width of the purifier 100, improving the neatness of the purifier 100.

[0127] Specifically, the ratio of the diameter R2 of the outer edge of the reflecting component 130 to the width L2 of the shell 110 can be 0.2, the ratio of the diameter R2 of the outer edge of the reflecting component 130 to the width L2 of the shell 110 can be 0.4, the ratio of the diameter R2 of the outer edge of the reflecting component 130 to the width L2 of the shell 110 can be 0.6, and the ratio of the diameter R2 of the outer edge of the reflecting component 130 to the width L2 of the shell 110 can be 0.8.

[0128] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0129] like Figure 5 As shown, the included angle between the reflective component 130 and the top wall 119 of the housing 110 is greater than or equal to 60 degrees and less than or equal to 85 degrees.

[0130] In this embodiment, the angle between the reflective component 130 and the top wall 119 of the housing 110 is greater than or equal to 60 degrees and less than or equal to 85 degrees. Since light is irradiated by the second light-transmitting surface 144 to the reflective component 130, and then reflected by the reflective component 130 to the environment surrounding the purifier 100, limiting the angle between the reflective component 130 and the top wall 119 of the housing 110 can prevent the light from being too concentrated or too divergent, thereby improving the brightness of the light while ensuring softness.

[0131] Specifically, the included angle between the reflective component 130 and the top wall 119 of the housing 110 is α.

[0132] Specifically, the angle α between the reflective component 130 and the top wall 119 of the housing 110 is greater than or equal to 60 degrees and less than or equal to 85 degrees. The angle α between the reflective component 130 and the top wall 119 of the housing 110 may be 60 degrees, the angle α between the reflective component 130 and the top wall 119 of the housing 110 may be 65 degrees, the angle α between the reflective component 130 and the top wall 119 of the housing 110 may be 70 degrees, the angle α between the reflective component 130 and the top wall 119 of the housing 110 may be 75 degrees, and the angle α between the reflective component 130 and the top wall 119 of the housing 110 may be 85 degrees.

[0133] Among them, when the angle α between the reflective component 130 and the top wall 119 of the shell 110 is 75 degrees, the light passing through the reflective component 130 to illuminate the surrounding environment has a better effect, which can make the light more flexible and avoid excessive or insufficient light convergence, making it easier for users to use.

[0134] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0135] The side wall of the shell 110 is provided with an air inlet 114, the top wall 119 of the shell 110 is provided with an air outlet 116, and the inside of the shell 110 has an air duct 118, and the air inlet 114 is connected with the air outlet 116 through the air duct 118; the circuit board 122 is arranged on the side wall of the shell 110, on the side of the air inlet 114 close to the air outlet 116.

[0136] In this embodiment, the side wall of the housing 110 is provided with an air inlet 114, and the top wall 119 of the housing 110 is provided with an air outlet 116. By providing the air inlet 114 and the air outlet 116, the gas can be circulated within the housing 110 of the purifier 100. The gas enters through the air inlet 114, is filtered and purified, and then discharged through the air outlet 116, thereby achieving a circulation purification of the ambient air. The housing 110 has an air duct 118 inside, and the air inlet 114 is connected to the air outlet 116 through the air duct 118, which can improve the airflow guidance efficiency and thus improve the purification efficiency. The circuit board 122 is arranged on the side wall of the housing 110, which can reduce the obstruction of the circuit board 122 to the air flow in the air duct 118, while facilitating the installation of the circuit board 122 and reducing the impact of the circuit board 122 on the air flow. The circuit board 122 is located on the side of the air inlet 114 close to the air outlet 116. The airflow flowing in the air duct 118 can dissipate heat from the circuit board 122, reduce the operating temperature of the circuit board 122, thereby extending the service life of the circuit board 122 and preventing the circuit board 122 from being damaged by high temperature.

[0137] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0138] The purifier 100 also includes an air outlet grille 160, which is arranged in the air duct 118 and is located on the side of the air duct 118 close to the air outlet 116. An air guide surface 162 is provided on the inner wall of the air outlet grille 160 close to the circuit board 122. The air guide surface 162 extends upward from the side close to the circuit board 122 to the side close to the center of the air duct 118 at an angle relative to the height direction of the shell 110.

[0139] In this embodiment, the purifier 100 also includes an air outlet grille 160, which is disposed within the air duct 118, on the side of the air duct 118 near the air outlet 116. An air guide surface 162 is provided on the inner wall of the air outlet grille 160 near the circuit board 122. The air guide surface 162 facilitates airflow. The air guide surface 162 extends upwardly and obliquely from the side near the circuit board 122 to the side near the center of the air duct 118, relative to the height of the housing 110. This allows for installation of the circuit board 122 and the reflective component 130, reduces wind resistance within the air duct 118, and further minimizes the impact of the circuit board 122 on the air duct 118. The air outlet grille 160 also prevents foreign matter from entering, thereby protecting the purifier 100. The provision of the air guide surface 162 ensures the secure installation of the circuit board 122 while minimizing its impact on the flow of purified air, thereby improving the purification efficiency of the purifier 100.

[0140] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0141] like Figure 5 As shown, the included angle between the air guide surface 162 and the height direction of the housing 110 is greater than or equal to 120 degrees and less than or equal to 150 degrees.

[0142] In this embodiment, the angle between the air guide surface 162 and the height direction of the housing 110 is greater than or equal to 120 degrees and less than or equal to 150 degrees. Setting the angle between the air guide surface 162 and the height direction of the housing 110 between 120 degrees and 150 degrees can guide the airflow and prevent the airflow velocity from being affected by the circuit board 122. At the same time, by limiting the angle between the air guide surface 162 and the height direction of the housing 110, the flow path of the airflow can be optimized and the purification efficiency can be improved.

[0143] Specifically, the included angle β between the wind guide surface 162 and the height direction of the housing 110 is greater than or equal to 120 degrees and less than or equal to 150 degrees.

[0144] Specifically, the angle β between the air guide surface 162 and the height direction of the housing 110 may be 120 degrees, the angle β between the air guide surface 162 and the height direction of the housing 110 may be 130 degrees, the angle β between the air guide surface 162 and the height direction of the housing 110 may be 140 degrees, and the angle β between the air guide surface 162 and the height direction of the housing 110 may be 150 degrees. When the angle β between the air guide surface 162 and the height direction of the housing 110 is 150 degrees, the flow path of the airflow can be better optimized and the purification efficiency can be improved.

[0145] Specifically, if Figure 7 As shown, a fan 180 can be set inside the purifier 100 to drive the gas to flow in the air duct 118. The fan 180 can be fixed by setting a bracket 182. A filter component 170 can be set inside the air duct 118 to filter the gas to purify the gas.

[0146] Specifically, if Figure 7 、 Figure 11 and Figure 12 As shown, the reflective component 130 is further provided with a reflective portion 132. The reflective portion 132 cooperates with the translucent component 140 to transmit light from the translucent component 140 to the reflective component 130, and then reflects light into the surrounding environment by the reflective surface 134 provided on the reflective component 130.
