Abstract
Description
Technical Field
[0001] This disclosure relates to the field of household appliance technology, specifically to an air purifier. Background Technology
[0002] An air purifier, also known as an air cleaner, air freshener, or purifier, is a household appliance that can adsorb, decompose, or transform various air pollutants (generally including PM2.5, dust, odors, formaldehyde, bacteria, etc.), effectively improving air cleanliness. Air purifiers contain a filter element that filters and adsorbs dust, odors, and other pollutants from the air to purify it. Additionally, to achieve a sterilization effect, an ultraviolet (UV) light source is installed inside the air purifier to sterilize the filter element. However, in some technologies, the UV light source in air purifiers irradiates a relatively small area of the filter element, resulting in a relatively poor sterilization effect.

[0024] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.
[0025] like Figures 1 to 5 As shown, the air purifier of this embodiment includes a housing 1, a filter element 2, and a sterilization component 3. The housing 1 has an air inlet and an air outlet. The filter element 2 and the sterilization component 3 are both disposed inside the housing 1, with the filter element 2 located between the air inlet and the air outlet. The sterilization component 3 includes an ultraviolet light source 31 and a reflector 32 with a reflective surface 321. The reflective surface 321 is curved, and the light emitted by the ultraviolet light source 31 is directed toward the reflective surface 321, while the light reflected by the reflective surface 321 is directed toward the filter element 2.
[0026] The air purifier of this embodiment includes a sterilization component 3 comprising an ultraviolet light source 31 and a reflector 32. The ultraviolet light source 31 emits light towards a reflective surface 321, and the reflective surface 321 reflects light towards the filter element 2. During use, the ultraviolet light emitted by the ultraviolet light source 31 illuminates the reflective surface 321 of the reflector 32, which then reflects the ultraviolet light onto the filter element 2, thus sterilizing the filter element 2. By making the reflective surface 321 curved, the area on which ultraviolet light illuminates the filter element 2 can be increased, improving the sterilization effect of the air purifier.
[0027] Optionally, the ultraviolet light source 31 can be an ultraviolet lamp.
[0028] Optionally, the ultraviolet light source 31 is located in the middle of the reflective surface 321.
[0029] By placing the ultraviolet light source 31 in the middle of the reflective surface 321, more ultraviolet light emitted by the ultraviolet light source 31 can illuminate the reflective surface 321, thereby increasing the area of ultraviolet light illuminating the filter element 2 and improving the sterilization effect of the air purifier.
[0030] In some embodiments, such as Figures 1 to 5 As shown, the housing 1 is provided with a purification chamber 101 and an air duct. The air duct is connected to the purification chamber 101 and is arranged on one side of the purification chamber 101 in a first direction. The purification chamber 101 includes a purification part 11 and an installation part 12. The installation part 12 is arranged on at least one side of the purification part 11 in a first direction. The filter element 2 is disposed in the purification part 11, and the sterilization component 3 is disposed in the installation part 12.
[0031] The filter element 2 inside the purification chamber 101 purifies the air. A fan is installed in the air duct to provide the power to drive the airflow. Driven by the fan, air enters the purification chamber 101 and is filtered and purified by the filter element 2. The purified air enters the air duct through the air inlet and exits through the air outlet to the outside of the air purifier. Inside the purification chamber 101, the ultraviolet light source 31 emits ultraviolet light in a direction away from the purification section 11. The reflective surface 321 is positioned facing the purification section 11, so that the ultraviolet light reflected by the reflective surface 321 illuminates the filter element 2 of the purification section 11.
[0032] By setting the air duct on one side of the purification chamber 101 in the first direction and setting the mounting part 12 on at least one side of the purification part 11 in the first direction, the orthogonal projection of the filter element 2 along the first direction can cover the surface of the purification chamber 101 perpendicular to the first direction, so that the air passing through the purification chamber 101 can flow through the filter element 2 to achieve air filtration and improve the air purification effect of the air purifier.
[0033] To make the technical solution of this disclosure easier to understand, the following description further illustrates the technical solution of this disclosure, taking the first direction being consistent with the front-back direction as an example. Wherein, the front-back direction is as follows... Figures 1 to 5 As shown.
[0034] For example, the air duct is located at the front of the purification chamber 101, the mounting part 12 is located at the front of the purification part 11, the ultraviolet light source 31 is located at the front of the filter element 2, and the reflector 32 is located at the front of the ultraviolet light source 31. The light emitted by the ultraviolet light source 31 faces forward, and the reflector 321 is arranged facing backward, so that the ultraviolet light reflected by the reflector 321 shines backward onto the filter element 2.
[0035] Optionally, the sterilization component 3 is disposed in the middle of the mounting portion 12 in a second direction, wherein the second direction is perpendicular to the first direction.
[0036] It should be noted that the second direction being perpendicular to the first direction includes the second direction being substantially perpendicular to the first direction.
[0037] By setting the sterilization component 3 in the middle of the mounting portion 12 in the second direction, the ultraviolet light reflected by the reflective surface 321 and tilted in the second direction can also irradiate the filter element 2. This allows more ultraviolet light to irradiate the filter element 2, thus achieving a better sterilization effect on the filter element 2 with fewer ultraviolet light sources 31 and reflective components 32. This simplifies the structure of the air purifier and reduces its cost.
[0038] To make the technical solution of this disclosure easier to understand, the following description further illustrates the technical solution of this disclosure, taking the second direction being consistent with the left and right directions as an example. Wherein, the left and right directions are as follows... Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown.
[0039] For example, the sterilization component 3 is positioned in the middle of the mounting portion 12 in the left-right direction, and the light reflected by the reflective surface 321 can radiate in the left-right direction and illuminate the filter element 2.
[0040] Optionally, such as Figure 2 As shown, the housing has at least two air inlets 102, and the purification chamber 101 and the air duct are connected through the air inlets 102. The at least two air inlets 102 are arranged at intervals along a third direction. The sterilization component 3 is disposed between two adjacent air inlets 102 in a third direction, wherein the third direction is perpendicular to the second direction and the first direction.
[0041] It should be noted that the third direction perpendicular to the second and first directions includes the third direction being substantially perpendicular to the second and first directions.
[0042] By placing the sterilization component 3 between two adjacent air inlets 102 in a third-direction orientation, not only can the sterilization component 3 be effectively prevented from affecting the air intake area of the air inlet 102, ensuring the air volume of the air purifier, but also the ultraviolet light reflected by the reflective surface 321 in a third-direction orientation can also irradiate the filter element 2. This allows more ultraviolet light to irradiate the filter element 2, thus achieving a better sterilization effect on the filter element 2 with fewer ultraviolet light sources 31 and reflective components 32. This simplifies the structure of the air purifier and reduces its cost.
[0043] To make the technical solution of this disclosure easier to understand, the following description uses a third-party direction consistent with the vertical direction as an example to further describe the technical solution of this disclosure. Wherein, the vertical direction is as follows... Figure 2 As shown.
[0044] For example, there are two air inlets 102 in the air duct, and the sterilization component 3 is arranged between the two air inlets 102 in the front-back direction. The light reflected by the reflective surface 321 can be dispersed in the front-back direction and irradiate the filter element 2.
[0045] Optionally, such as Figure 1 and Figure 2 As shown, there are multiple ultraviolet light sources 31 and multiple reflectors 32, with each reflector 32 corresponding to at least one ultraviolet light source 31. At least two reflectors 32 are arranged at intervals along a second direction, and at least two reflectors 32 are arranged at intervals along a third direction.
[0046] For example, such as Figure 2 As shown, there are four ultraviolet light sources 31 and four reflectors 32, with each reflector 32 corresponding to one ultraviolet light source 31. The four reflectors 32 are divided into two groups, each group including two reflectors 32. The two groups of reflectors 32 are arranged at intervals along the vertical direction, and the two reflectors 32 in the same group are arranged at intervals along the horizontal direction.
[0047] By setting the number of ultraviolet light sources 31 and reflectors 32 to multiple, and arranging the multiple reflectors 32 in the manner described above, more ultraviolet light can be irradiated onto the filter element 2 under the condition that the number of ultraviolet light sources 31 and reflectors 32 is fixed, thereby improving the sterilization effect of the air purifier.
[0048] Optionally, such as Figures 3 to 5 As shown, there are multiple sterilization components 3, which are arranged on opposite sides of the air inlet 102 in a third-direction orientation. In the third-direction orientation, the reflective element 32 located on one side of the air inlet 102 is arranged at an angle toward the other side of the air inlet 102.
[0049] For example, such as Figure 3 and Figure 5 As shown, there is one air inlet 102 in the air duct and two sterilization components 3. The two sterilization components 3 are a first sterilization component 301 and a second sterilization component 302. The first sterilization component 301 is located on the lower side of the air inlet 102, and the reflective surface 321 of the first sterilization component 301 is arranged upward. The second sterilization component 302 is located on the upper side of the air inlet 102, and the reflective surface 321 of the second sterilization component 302 is arranged downward.
[0050] By setting the number of sterilization components 3 to multiple, and arranging the reflector 32 on one side of the air inlet 102 in a tilted manner towards the other side of the air inlet 102, a better sterilization effect on the filter element 2 can be achieved with a smaller number of ultraviolet light sources 31 and reflectors 32, simplifying the structure of the air purifier and reducing the cost of the air purifier.
[0051] It should be noted that the tilt angle of the reflective surface 321 is designed as needed to ensure that the ultraviolet light of the sterilization component 3 can irradiate the filter element 2 more. The curved shape of the reflective surface 321 can be optimized through optical design.
[0052] Optionally, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the sterilization component 3 also includes a mounting bracket 33, which is connected to the housing 1. Multiple reflective elements 32 and the mounting bracket 33 are integrally formed.
[0053] For example, the reflector 32 and the mounting bracket 33 are integrally injection molded, and the surface of the reflector 32 is electroplated with silver to form a reflective surface 321.
[0054] By integrally molding multiple reflectors 32 and mounting brackets 33, the structure of the sterilization component 3 can be simplified, the assembly efficiency of the air purifier can be improved, and the cost of the air purifier can be reduced.
[0055] Optionally, the mounting bracket 33 is detachably connected to the housing 1.
[0056] For example, mounting bracket 33 is connected to housing 1 by screws.
[0057] The reflector 32 can be easily replaced by detachably connecting the mounting bracket 33 to the housing 1.
[0058] Optionally, the sterilization component 3 also includes a lamp holder 34, which is connected to the housing 1, and multiple ultraviolet light sources 31 are mounted on the same lamp holder 34.
[0059] By mounting multiple ultraviolet light sources 31 on the same lamp holder 34, the assembly of the air purifier can be performed by first installing the multiple ultraviolet light sources 31 on the lamp holder 34 and then connecting the lamp holder 34 to the housing 1, thereby improving the installation efficiency of the multiple ultraviolet light sources 31. This increases the assembly efficiency of the air purifier and reduces its cost.
[0060] Optionally, the lamp holder 34 is detachably connected to the housing 1.
[0061] For example, mounting bracket 33 is connected to housing 1 by screws.
[0062] The ultraviolet light source 31 can be easily replaced by detachably connecting the lamp holder 34 to the housing 1.
