Description

air purifier

[0001] This application claims priority to Chinese Patent Application No. 2025100342100, filed on January 8, 2025, entitled "Air Purifier", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of air purification technology, specifically to a purifier. Background Technology

[0003] Currently, in related technologies, air purifiers purify the surrounding air by drawing in outside air, purifying it, and then expelling it outside the purifier. The air intake of the purifier is usually located at the bottom, and the air outlet is usually located at the top. This arrangement results in a long airflow path from the purifier to the exhaust, leading to greater air resistance within the purifier. Technical solutions

[0004] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the first aspect of this application proposes a purifier.

[0006] The second aspect of this application proposes a purifier.

[0007] In view of the above, a first aspect of this application provides an air purifier, including a housing assembly, a fan assembly, and an electronic control assembly. The housing assembly is provided with an air inlet and an air outlet; the fan assembly is disposed inside the housing assembly, and the air duct of the fan assembly is connected to the air outlet; the electronic control assembly is disposed on top of the fan assembly; wherein, in the height direction of the purifier, the air outlet is located at the top of the air duct and is closer to the air inlet than the electronic control assembly.

[0008] In this technical solution, the air purifier includes a shell assembly, a fan assembly, and an electrical control assembly. The shell assembly has an air inlet and an air outlet, allowing the purifier to absorb outside air through the inlet and discharge purified air through the outlet, thus achieving airflow circulation. The fan assembly is housed inside the shell assembly for installation, and the shell assembly protects the fan assembly. The fan assembly's duct is connected to the air outlet. During operation, the fan assembly generates airflow, continuously drawing outside air into the purifier and into the duct, while also driving the purified air to be discharged through the outlet. The electrical control assembly is located on top of the fan assembly for installation and fixation, and it controls the operation of the purifier. In terms of the air purifier's height, the air outlet is located at the top of the air duct and closer to the air inlet than the electronic control components. This allows for adjustments to the outlet's position, moving it downwards to the top of the air duct, making the airflow path more direct and reducing the airflow path within the purifier. By placing the air outlet at the top of the fan assembly's air duct and below the electronic control components, this application shortens the airflow path within the purifier. Due to the shortened air duct path, the resistance encountered by the air during flow is correspondingly reduced. This reduced air resistance allows the fan assembly to easily drive airflow, improving the purifier's air purification speed and efficiency, thereby enhancing the purifier's performance.

[0009] A second aspect of this application provides an air purifier, including a housing assembly and a fan assembly. The housing assembly has an air inlet and an air outlet; the fan assembly is mounted on the housing assembly and includes a fan wheel, a motor, and a first bracket. The first bracket has a first mounting cavity, and the motor is connected to the fan wheel and disposed within the first mounting cavity; wherein the air outlet is located at the top of the air duct of the fan assembly and is closer to the air inlet than to the first mounting cavity.

[0010] In this technical solution, the purifier includes a shell assembly and a fan assembly. The shell assembly has an air inlet and an air outlet, allowing the purifier to absorb outside air through the air inlet and discharge purified air through the air outlet, thus achieving airflow. The fan assembly is installed on the shell assembly. The fan assembly includes a fan wheel, a motor, and a first bracket. The first bracket has a first mounting cavity, and the motor is connected to the fan wheel, allowing the motor to drive the fan wheel to rotate, thereby generating airflow. The motor is located inside the first mounting cavity, which provides some protection for the motor, reducing the possibility of it being impacted or damaged by external forces. The air outlet is located at the top of the air duct of the fan assembly and is closer to the air inlet than the first mounting cavity, allowing for adjustment of the outlet's position. The outlet is lowered and located directly at the top of the air duct, making the airflow path more direct and reducing the airflow path inside the purifier. This application shortens the airflow path within the purifier by placing the air outlet at the top of the fan assembly's duct and closer to the air inlet than the first mounting cavity. This shortened duct path reduces air resistance during airflow. The reduced air resistance allows the fan assembly to easily drive airflow, improving the purifier's air purification speed and efficiency, thereby enhancing its performance.

Embodiments of the present invention

[0025] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0027] The air purifier 100 according to some embodiments of the present application is described below with reference to Figures 1 to 10.

[0028] As shown in Figures 1 and 2, one embodiment of this application provides an air purifier 100, including a housing assembly 102, a fan assembly 112, and an electronic control assembly 120. The housing assembly 102 is provided with an air inlet 152 and an air outlet 154; the fan assembly 112 is disposed inside the housing assembly 102, and the air duct 156 of the fan assembly 112 is connected to the air outlet 154; the electronic control assembly 120 is disposed on top of the fan assembly 112; wherein, in the height direction of the air purifier 100, the air outlet 154 is located at the top of the air duct 156 and is closer to the air inlet 152 than the electronic control assembly 120.

[0029] In some embodiments, the purifier 100 includes a housing assembly 102, a fan assembly 112, and an electronic control assembly 120. The housing assembly 102 is provided with an air inlet 152 and an air outlet 154, allowing the purifier 100 to absorb outside air through the air inlet 152 and discharge purified air through the air outlet 154, thus achieving airflow circulation. The fan assembly 112 is disposed inside the housing assembly 102 for installation, allowing the housing assembly 102 to protect the fan assembly 112. The air duct 156 of the fan assembly 112 communicates with the air outlet 154. When the fan assembly 112 is running, it generates airflow, continuously drawing outside air into the purifier 100 and into the air duct 156. The fan assembly 112 also drives the purified air to be discharged through the air outlet 154. The electronic control component 120 is located on top of the fan assembly 112 for installation and fixation. The electronic control component 120 controls the operation of the purifier 100. In the height direction of the purifier 100, the air outlet 154 is located at the top of the air duct 156 and closer to the air inlet 152 than the electronic control component 120. This allows for position adjustment of the air outlet 154, lowering its position to directly over the top of the air duct 156, making the airflow path more direct and reducing the airflow path within the purifier 100. By placing the air outlet 154 at the top of the air duct 156 of the fan assembly 112 and below the electronic control component 120, this application shortens the airflow path within the purifier 100. Due to the shortened path of the air duct 156, the resistance encountered by the air during flow is correspondingly reduced. The reduction in wind resistance allows the fan assembly 112 to easily drive airflow, improving the air purification speed and efficiency of the purifier 100, thereby enhancing the performance of the purifier 100.

[0030] Specifically, this application positions the air outlet 154 at the top of the air duct 156 of the fan assembly 112 and below the electronic control assembly 120, allowing the purifier 100 to discharge air below the electronic control assembly 120. This preserves space for the power board 130 and the main control board. By using a side opening to position the air outlet 154 roughly flush with the motor 114 mounting location, the space in the air duct 156 is significantly reduced, lowering air resistance. With the same volume of purifier 100, the performance of the purifier 100 can be improved by shortening the path of the air duct 156.

[0031] Specifically, in Figure 1, arrow A indicates the height direction of purifier 100.

[0032] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0033] As shown in Figure 1, the housing assembly 102 includes an air inlet grille 104, a first housing 106, and an air outlet grille 108. The air inlet grille 104 is provided with an air inlet 152; the first housing 106 is connected to the air inlet grille 104; the air outlet grille 108 is located on the side of the first housing 106 away from the air inlet grille 104, and the air outlet grille 108 is provided with an air outlet 154.

[0034] In some embodiments, the housing assembly 102 includes an air inlet grille 104, a first housing 106, and an air outlet grille 108. The air inlet grille 104 is provided with an air inlet 152 for arranging the air inlet 152 to introduce air to be purified. The first housing 106 is connected to the air inlet grille 104 for installation. The air outlet grille 108 is located on the side of the first housing 106 away from the air inlet grille 104, and is provided with an air outlet 154, allowing air to flow smoothly from the air inlet 152, be accelerated and purified by the fan assembly 112, and finally be discharged from the air outlet 154. The position of the air outlet 154 is flush with the installation position of the fan assembly 112, greatly reducing the path of the air duct 156, avoiding unnecessary bends and obstructions, and correspondingly reducing the resistance encountered by the air during flow. The reduced wind resistance allows the fan assembly 112 to work more efficiently, improving the air purification speed and efficiency of the purifier 100, reducing energy consumption, and extending the service life of the purifier 100.

[0035] Specifically, the first housing 106 is in the shape of a ring and serves as the outer shell of the purifier 100.

[0036] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0037] As shown in Figures 1, 3, and 4, the air outlet grille 108 includes a plurality of air guide sections 110; the plurality of air guide sections 110 are arranged in a ring shape, and the height of the air guide section 110 near the axis of the fan assembly 112 is higher than that of the air guide section 110 away from the axis of the fan assembly 112; or each of the plurality of air guide sections 110 extends radially along the fan assembly 112, and the end of the air guide section 110 near the axis of the fan assembly 112 is higher than the end of the air guide section 110 away from the axis of the fan assembly 112.

[0038] In some embodiments, the air outlet grille 108 includes a plurality of air guide sections 110. The plurality of air guide sections 110 are arranged in a ring shape, with the height of the air guide section 110 closest to the axis of the fan assembly 112 being higher than the height of the air guide section 110 furthest from the axis of the fan assembly 112, thus causing the air outlet grille 108 to be inclined. Each air guide section 110 extends radially along the fan assembly 112, with one end of the air guide section 110 closest to the axis of the fan assembly 112 being higher than the end of the air guide section 110 furthest from the axis of the fan assembly 112, thereby achieving an inclined arrangement of the air outlet grille 108. By providing a downwardly inclined air outlet grille 108, the projected area of ​​the air outlet grille 108 in the horizontal direction is increased, thereby increasing the air outlet area. The increased air outlet area means that air can pass through the purifier 100 more quickly, thereby improving air purification efficiency. Furthermore, by setting the downward-sloping air outlet grille 108, compared to the upward-sloping method, the distance between the air outlet grille 108 and the guide vane 142 can be reduced or kept unchanged. This allows the downward-sloping air outlet grille 108 and the guide vane 142 to guide the air out at a certain angle, making the exhaust air distribution more uniform.

[0039] Specifically, in Figure 1, arrow H represents the axis of the fan assembly 112.

[0040] Specifically, in Figure 3, arrow I indicates the height direction of the air guide 110.

[0041] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0042] As shown in Figures 1, 5, and 6, the fan assembly 112 includes a first support 134 and a plurality of guide vanes 142. The plurality of guide vanes 142 are arranged circumferentially along the first support 134, and in the height direction of the purifier 100, the side of the guide vane 142 connected to the first support 134 to the side of the guide vane 142 near the first housing 106 is arranged downwardly at an angle.

[0043] In some embodiments, the fan assembly 112 includes a first bracket 134 and a plurality of guide vanes 142. The plurality of guide vanes 142 are arranged circumferentially along the first bracket 134 to facilitate their installation. In the height direction of the purifier 100, the guide vanes 142 are arranged at an angle from the side connected to the first bracket 134 to the side near the first housing 106, allowing the plurality of guide vanes 142 to form an inclined surface. This inclined surface has a larger area than a horizontal straight surface, directly increasing the effective area of ​​the air outlet 154, allowing air to flow out of the purifier 100 more smoothly. The increased area of ​​the air outlet 154 and the optimized airflow distribution allow air to pass through the purifier 100 more quickly and be distributed more evenly in the indoor space. Under the same conditions, the larger the air outlet area of ​​the air outlet grille 108, the better the performance of the purifier 100. The guide vane 142, with its inner high and outer low design, is more conducive to pushing airflow from the inner high to the lower position, and is more conducive to the outward diffusion of airflow.

[0044] Specifically, the inclined surface formed by the multiple guide vanes 142 has a larger area than the horizontal straight surface, directly increasing the area of ​​the air outlet 154. This results in a corresponding increase in the air outlet area of ​​the matching air outlet grille 108. Under the same conditions, the larger the air outlet area of ​​the air outlet grille 108, the better the performance. The horizontally arranged guide vanes 142 lead to an increase in the overall height of the air duct 156 system, i.e., an increase in the size of D in Figure 1. The multiple guide vanes 142 in this application form an inclined shape with a higher inner surface and a lower outer surface, reducing unnecessary height of the air duct 156 and further compressing the size of the air duct 156. This also reduces the air resistance inside the air duct 156 from the side. At the same time, when the size of D is reduced, the upper part of the purifier 100 appears smaller in size. With the multiple guide vanes 142 in this application, the airflow diffuses in all directions. The design of the guide vanes 142 with a higher inner surface and a lower outer surface is more conducive to squeezing the airflow from the higher inner surface to the lower outer surface, which is more conducive to the outward diffusion of the airflow.

[0045] Specifically, in Figure 1, D represents the length of the air duct 156.

[0046] Specifically, in Figure 5, arrow B indicates the circumferential direction of the first support 134.

[0047] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0048] As shown in Figures 4 and 5, the guide vanes 142 are arranged at an angle in the circumferential direction of the first support 134.

[0049] In some embodiments, guide vanes 142 are arranged at an angle in the circumferential direction of the first support 134, so that multiple guide vanes 142 are arranged in the circumferential direction of the first support 134, which can guide the airflow toward the position of the air outlet grille 108, so that the air can flow out of the purifier 100 more smoothly. When the guide vanes 142 are arranged at an angle in both the height direction of the purifier 100 and the circumferential direction of the first support 134, the guide vanes 142 can be arranged at an angle in both directions, which can more flexibly adjust the direction and speed of the airflow. This not only increases the area of ​​the air outlet 154, but also allows the air to pass through the purifier 100 more quickly, so that the air can be discharged more smoothly.

[0050] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0051] As shown in Figure 4, in the height direction of the purifier 100, the distance between the air outlet grille 108 and the guide vane 142 is the second distance, which increases from the inner peripheral edge of the air outlet grille 108 to the outer peripheral edge of the air outlet grille 108.

[0052] In some embodiments, the distance between the air outlet grille 108 and the guide vane 142 in the height direction of the purifier 100 is a second distance. This second distance increases from the inner peripheral edge of the air outlet grille 108 to the outer peripheral edge of the air outlet grille 108, thereby adjusting the distance between the air outlet grille 108 and the guide vane 142, making the structure of the purifier 100 more compact. By adjusting the distance between the air outlet grille 108 and the guide vane 142, air resistance during airflow can be reduced, and the length of the air duct 156 can be shortened. By increasing the distance between the outer peripheral edge of the air outlet grille 108 and the guide vane 142, the airflow at the outer peripheral edge of the air outlet grille 108 is greater, which reduces the noise generated by the airflow impacting the air outlet grille 108, thus solving the problem of excessive airflow noise in the purifier 100.

[0053] Specifically, in Figure 4, G represents the second distance.

[0054] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0055] As shown in Figures 1, 5 and 6, in the height direction of the purifier 100, the first bracket 134 is provided with an upwardly protruding mounting part 140, and a first mounting cavity 158 is provided inside the mounting part 140; the fan assembly 112 includes a motor 114, and the motor 114 is disposed inside the first mounting cavity 158.

[0056] In some embodiments, in the height direction of the purifier 100, the first bracket 134 is provided with an upwardly protruding mounting portion 140, and a first mounting cavity 158 is provided within the mounting portion 140; the fan assembly 112 includes a motor 114, which is disposed within the first mounting cavity 158. The mounting portion 140 can effectively fix the position of the motor 114, ensuring that it will not shake or shift during operation. The mounting portion 140 and the first mounting cavity 158 can provide a certain degree of protection for the motor 114, reducing the possibility of it being subjected to external impacts or damage. Because the motor 114 is stably supported and protected, its operation is more stable and reliable, thereby improving the overall purification efficiency of the purifier 100.

[0057] Specifically, motor 114 is the power component of purifier 100, the core power source of the whole machine, and is installed in the middle area of ​​the first bracket 134.

[0058] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0059] As shown in Figure 1, the fan assembly 112 also includes a vortex housing 116 and a fan wheel 118. The vortex housing 116 is connected to the first housing 106 and is located inside the first housing 106; the fan wheel 118 is connected to the motor 114 and is located inside the vortex housing 116, and there is a duct 156 between the fan wheel 118 and the interior of the vortex housing 116.

[0060] In some embodiments, the fan assembly 112 further includes a vortex housing 116 and a fan wheel 118. The vortex housing 116 is connected to the first housing 106 and located inside the first housing 106 for mounting the vortex housing 116. The fan wheel 118 is connected to the motor 114 and located inside the vortex housing 116 for mounting the fan wheel 118 and the motor 114, so that the motor 114 can drive the fan wheel 118 to rotate, thereby generating airflow. There is an air duct 156 between the fan wheel 118 and the interior of the vortex housing 116, so that when the fan wheel 118 rotates, it can drive the air entering the purifier 100 to be discharged through the air duct 156 and the air outlet 154. When the fan wheel 118 rotates and agitates the air to form an airflow, the airflow enters the interior of the vortex housing 116. The vortex housing 116 can effectively guide the airflow, slowing down the high-speed rotating airflow and guiding it towards the air outlet 154. The fan assembly 112, through the vortex 116, impeller 118, and air duct 156, can effectively draw in, accelerate, and discharge air, thereby improving air purification efficiency.

[0061] Specifically, the wind turbine 118 is driven by the motor 114, which can stir the air to form an airflow.

[0062] Specifically, as shown in Figure 1, the purifier 100 also includes a filter 164, which is disposed within the air inlet grille 104 and serves as the core component for purification and adsorption in the purifier 100. The filter 164 purifies the air drawn in through the air inlet 152. The bottom of the air duct 156 is the air inlet, and the airflow passing through the filter 164 directly enters the interior of the air duct 156 through the meshed air inlet at the bottom of the air duct 156.

[0063] Specifically, the top of the vortex housing 116 is connected to the first bracket 134 and fixed by screws.

[0064] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0065] As shown in Figure 1, the electrical control assembly 120 includes a power supply box 122, a power supply board 130, and an electrical control board 132. The power supply box 122 is located on the side of the first bracket 134 away from the fan assembly 112; the power supply board 130 is located inside the power supply box 122; and the electrical control board 132 is located on the side of the power supply box 122 away from the fan assembly 112.

[0066] In some embodiments, as shown in Figures 7, 8, and 9, the electronic control assembly 120 includes a power supply box 122, a power board 130, and an electronic control board 132. The power supply box 122 is disposed on the side of the first bracket 134 away from the fan assembly 112 for mounting. The power board 130 is disposed within the power supply box 122 for mounting. The electronic control board 132 is disposed on the side of the power supply box 122 away from the fan assembly 112 for mounting. The power supply box 122 ensures complete isolation of the power board 130 from the external environment, effectively preventing safety issues such as short circuits, damage, or electric shocks caused by external environmental factors, thereby improving the overall safety and reliability of the unit. The power board 130, disposed within the power supply box 122, is responsible for receiving externally input electrical energy and providing the necessary power to the electronic control board 132 and other possible components, ensuring the air purifier 100 can operate normally. The electronic control board 132 controls the relevant circuits to realize the various functions of the air purifier 100, so that users can easily adjust the various functions of the air purifier 100, improving the ease of use and comfort.

[0067] Specifically, the power supply box 122 is made of fireproof material and is installed on the first bracket 134. The power supply box 122 is fitted with a power board 130 to ensure complete isolation of the power board 130 and ensure the safety of the whole machine.

[0068] Specifically, the power board 130 is installed inside the power box 122 and is connected to the external power grid via a power cord. Through the voltage conversion of the power board 130, the voltage is converted into the voltage required by the whole machine and supplied to the whole machine.

[0069] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0070] As shown in Figures 1, 3 and 10, the purifier 100 also includes a second housing 144, which includes a top cover 160 and a first extension 172. The first extension 172 is connected to the housing assembly 102, and the top cover 160 covers the first extension 172.

[0071] In some embodiments, the purifier 100 further includes a second housing 144, which includes a top cover 160 and a first extension 172. The first extension 172 is connected to the housing assembly 102 to enable installation between the second housing 144 and the housing assembly 102. The top cover 160 covers the first extension 172, thereby protecting the first extension 172.

[0072] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0073] As shown in Figures 1, 2 and 4, the first extension has a guide surface 150 on the side near the air outlet 154. The guide surface 150 extends in an arc shape from the inner peripheral edge of the air outlet grille 108 to the outer peripheral edge of the air outlet grille 108.

[0074] In some embodiments, the first extension has a guide surface 150 on the side near the air outlet 154. The guide surface 150 extends in an arc shape from the inner peripheral edge of the air outlet grille 108 to the outer peripheral edge of the air outlet grille 108. This arrangement of the guide surface 150 allows the second housing 144 to effectively guide the airflow, making the airflow smoother when it exits the air outlet 154. This reduces airflow turbulence and eddies, significantly improving the air delivery efficiency of the purifier 100 and thus enhancing the overall performance of the unit. Guided by the guide surface 150, the airflow can be more evenly distributed across the air outlet 154, avoiding situations where the local airflow is too strong or too weak, thereby improving the air delivery efficiency and comfort of the purifier 100.

[0075] Specifically, in Figure 2, arrow C indicates the circumferential direction of the air grille 108.

[0076] Specifically, the first extension 172 is an arc-shaped portion that is recessed into the second housing 144, making the first extension 172 curved so that the airflow blown out by the air outlet grille 108 can be directed toward the first extension 172. Due to the curved design of the first extension 172, the first extension 172 can guide the blown airflow, making the air delivery range of the purifier 100 wider.

[0077] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0078] As shown in Figure 1, the air vent grille 108 or the first bracket 134 is provided with a second extension 174 extending toward the top cover 160, and the first extension 172 is connected to the second extension 174.

[0079] In some embodiments, the air outlet grille 108 or the first bracket 134 is provided with a second extension 174 extending toward the top cover 160. The first extension 172 is connected to the second extension 174 to install the first extension 172, so that the second extension 174 can support the first extension 172 and improve the stability of the second housing 144 after installation. Furthermore, by providing the second extension 174, the distance between the air outlet grille 108 and the first extension 172 can be increased, thereby allowing the airflow discharged from the air outlet grille 108 to be discharged more smoothly and gently.

[0080] Specifically, the air vent grille 108 is provided with a second extension 174 extending toward the top cover 160.

[0081] Specifically, the first bracket 134 is provided with a second extension 174 extending toward the top cover 160.

[0082] Specifically, the second extension 174 is an arc-shaped part that is recessed into the air outlet grille 108 or the first bracket 134, so that the second extension 174 is curved, so that the airflow blown out of the air outlet grille 108 can blow towards the second extension 174, so that the second extension 174 can guide the blown airflow, making the air delivery range of the purifier 100 wider.

[0083] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0084] The top cover 160, the first extension 172, the second extension 174 and the first bracket 134 enclose the second mounting cavity 176; or the top cover 160, the first extension 172, the second extension 174 and the air outlet grille 108 enclose the second mounting cavity 176; the electronic control component 120 is installed in the second mounting cavity 176.

[0085] In some embodiments, the top cover 160, the first extension 172, the second extension 174, and the first bracket 134 enclose a second mounting cavity 176 to facilitate the arrangement of the second mounting cavity 176. The top cover 160, the first extension 172, the second extension 174, and the air outlet grille 108 enclose the second mounting cavity 176 to facilitate the arrangement of the second mounting cavity 176. The electronic control assembly 120 is mounted in the second mounting cavity 176, thereby providing installation space for the electronic control assembly 120, and the second mounting cavity 176 provides protection for the electronic control assembly 120. The second mounting cavity 176 enhances the safety of the purifier 100, preventing users from contacting potentially dangerous components such as the power supply box 122 and the electronic control board 132.

[0086] Specifically, the top cover 160, the first extension 172, the second extension 174 and the first bracket 134 enclose the second mounting cavity 176.

[0087] Specifically, the top cover 160, the first extension 172, the second extension 174 and the air vent grille 108 form a second mounting cavity 176.

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

[0089] As shown in Figures 1 and 4, in the radial direction of the fan assembly 112, the curvature of the air guide surface 150 decreases from the side of the air guide surface 150 near the fan assembly 112 to the side of the air guide surface 150 near the first housing 106.

[0090] In some embodiments, the curvature of the air guide surface 150 in the radial direction of the fan assembly 112 decreases from the side of the air guide surface 150 near the fan assembly 112 to the side of the air guide surface 150 near the first housing 106. This adjustment of the air guide surface 150 allows the air blown vertically from the air outlet grille 108 to be effectively guided into a horizontal direction, thus widening the air delivery range of the purifier 100. Horizontal air delivery helps enhance indoor air circulation, enabling the purifier 100 to purify indoor air more quickly and distribute it evenly to all corners, improving purification efficiency. The arc of the second housing 144 transitions smoothly from the inside out, eventually becoming approximately horizontal. This ensures that the airflow is blown outwards in an approximately horizontal direction during outward diffusion, thus guiding the air blown vertically from the air outlet grille 108 into a horizontal direction. This transforms the purifier 100 into a fan-like product that can blow air in all directions. Horizontal airflow allows users to experience a more comfortable and even airflow effect, avoiding the discomfort that may be caused by vertical airflow, thereby improving the user experience.

[0091] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0092] As shown in Figures 4, 7 and 8, the power supply box 122 includes a base 124 and a box 126, with the box 126 fastened to the base 124; the first bracket 134 is provided with a first screw post 136, which passes through the base 124 and extends toward the second housing 144; the purifier 100 also includes a first connector 146, which passes through the second housing 144 and is connected to the first screw post 136.

[0093] In some embodiments, the power supply box 122 includes a base 124 and a housing 126, with the housing 126 fastened to the base 124 for installation. A first bracket 134 is provided with a first screw post 136, which passes through the base 124 and extends towards the second housing 144 for arrangement. The purifier 100 also includes a first connector 146, which passes through the second housing 144 and connects to the first screw post 136 for installation. Through the cooperation of the first screw post 136 and the first connector 146, the power supply box 122 can be easily fixed in the corresponding position of the purifier 100. This connection method also facilitates subsequent disassembly, making it beneficial for regular maintenance or replacement of the power supply box 122.

[0094] Specifically, there are multiple first screw posts 136 and multiple first connectors 146.

[0095] Specifically, there are two first screw posts 136 and two first connectors 146.

[0096] Specifically, there are three first screw posts 136 and three first connectors 146.

[0097] Specifically, the first connector 146 can be a screw.

[0098] Specifically, the base 124 is the lower cover of the power supply box 122, and the box 126 is the upper cover of the power supply box 122.

[0099] Specifically, as shown in Figures 5 and 6, the structure of the first bracket 134 is mainly divided into upper and lower parts. The lower part is mainly used to install the motor 114. There is a groove in the middle, that is, the mounting part 140 is a groove. The groove has a first mounting cavity 158, which is used to accommodate the power pack part of the motor 114. There are four screw holes around the groove, which are effectively fixed to the motor 114 by four screws.

[0100] As shown in Figures 7, 8 and 9, the lower part of the first bracket 134 is provided with a second screw post 138. The purifier 100 also includes a second connector, which can pass through the air outlet grille 108 and connect to the second screw post 138.

[0101] Specifically, there are multiple second connectors and multiple second screw posts 138.

[0102] Specifically, there are two second connectors and two second screw posts 138.

[0103] Specifically, there are three second connectors and three second screw posts 138.

[0104] Specifically, the second connector can be a screw.

[0105] As shown in Figures 7, 8, and 9, the first bracket 134 has a protrusion formed by the groove of the power pack for accommodating the motor 114 in the middle. Three first screw posts 136 and three second screw posts 138 are spaced around the first bracket 134. The three second screw posts 138 are used to fix the air outlet grille 108 with screws. The three first screw posts 136 are used to fit the base 124. The lower cover of the second housing 144 is then installed on the base 124 through a sleeve structure. Finally, it is fixed by the first connector 146 on the second housing 144. The first connector 146 locks the second housing 144, the base 124, and the first bracket 134 in a series of three.

[0106] Specifically, as shown in Figure 3, the first bracket 134 is provided with a first fastening position 166, and multiple first fastening positions 166 are arranged circumferentially around the outer ring of the first bracket 134. The air outlet grille 108 is provided with a second fastening position 168, and multiple second fastening positions 168 are arranged circumferentially around the outer ring of the air outlet grille 108. The first fastening positions 166 and the second fastening positions 168 can be engaged, that is, the first bracket 134 and the air outlet grille 108 form a snap-fit ​​engagement on the outer ring, and the air outlet grille 108 is fixed on the outer ring of the first bracket 134 through the snap-fit ​​engagement.

[0107] Specifically, as shown in Figures 7, 8, and 9, the power supply box 122 includes a box body 126 and a base 124. A first bracket 134 is provided with three first screw posts 136 and three second screw posts 138. The three first screw posts 136 fit around the base 124 to prevent movement. The three second screw posts 138 cooperate with the air outlet grille 108. A second connector can pass through the air outlet grille 108 and connect to the second screw posts 138. Therefore, the air outlet grille 108 is fixed to the inner ring of the first bracket 134 by screws. The power board 130 is installed inside the base 124 and fixed by clips and screws. The base 124 and the box body 126 are fixed together by a ring of clips or screws around the edge, ensuring that the box body 126 is simultaneously fixed while the first bracket 134 fits around the base 124. Multiple wiring holes 128 are provided between the base 124 and the box 126 to ensure that the wiring harness on the power board 130 can be properly led out. The main control board is installed on the top of the housing 126 and fixed with screws. At the same time, the remaining space in the inner circle of the first bracket 134 is used for wiring to realize the assembly of electrical components, ensuring that the entire electronic control assembly 120 of the purifier 100 can be installed in the cavity formed by the second housing 144 and the first bracket 134. Finally, the second housing 144 is put on, and the second housing 144 is also fixed to the first bracket 134 by the first connector 146. At the same time, the base 124 needs to be put on in the middle to ensure a firm installation of the three. The first bracket 134 has a wire hole 170 to ensure that the external power cord can be connected to the internal power board 130.

[0108] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0109] As shown in Figures 1, 3 and 4, in the radial direction of the fan assembly 112, the air outlet grille 108 extends in an arc shape from the side near the fan assembly 112 to the side near the first housing 106.

[0110] In some embodiments, in the radial direction of the fan assembly 112, the air outlet grille 108 extends in an arc shape from the side near the fan assembly 112 to the side near the first housing 106. This arc-shaped extension of the air outlet grille 108 effectively guides the airflow from the fan assembly 112, allowing it to flow more smoothly out of the air outlet 154. This reduces the residence time of the airflow inside the purifier 100, resulting in a more uniform airflow distribution and thus improving purification efficiency. Through its arc-shaped design, the air outlet grille 108 allows the airflow to be blown out in a softer and more uniform manner, avoiding situations where the local airflow is too strong or too weak, thereby optimizing the air delivery effect and improving the user experience.

[0111] Specifically, the top cover 160 is load-bearing, allowing users to place items on it.

[0112] Specifically, the top cover 160 is flat, making it convenient for users to place items or decorate with other ornaments.

[0113] Specifically, the top of the second housing 144 can support the top cover 160, and the lower end of the second housing 144 is connected to the air outlet grille 108, playing a connecting role. At the same time, the outer surface of the second housing 144 is an arc surface with a gradually smooth curvature transition, which together with the arc surface of the air outlet grille 108 forms the air outlet 154 guide layer of the air duct 156 system.

[0114] Specifically, the air outlet grille 108 serves as the air outlet 154 of the purifier 100. The outer surface of the air outlet 154 is a curved surface with an inclined arc transition that is higher on the inside and lower on the outside, which is conducive to the guidance of airflow.

[0115] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0116] As shown in Figures 1 and 2, the air outlet grille 108 includes a plurality of air guide sections 110, each of which extends in a ring shape and is arranged radially along the fan assembly 112. An air outlet 154 is formed between two adjacent air guide sections 110.

[0117] In some embodiments, the air outlet grille 108 includes a plurality of air guide sections 110, each of which extends in a ring shape and is arranged radially along the fan assembly 112 to facilitate installation of the air guide sections 110. An air outlet 154 is formed between two adjacent air guide sections 110 to allow the purifier 100 to discharge purified air. The radial arrangement of the air guide sections 110 along the fan assembly 112, forming multiple air outlets 154, buffers the airflow accelerated by the impeller 118 in the air outlet 154 area, reducing the wind speed and allowing the airflow to flow out more smoothly from the air outlet 154. After being buffered and dispersed by the air guide sections 110, the airflow becomes softer and more uniform, improving user comfort.

[0118] Specifically, in Figure 1, arrow E represents the radial direction of the fan assembly 112.

[0119] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0120] As shown in Figure 2, the distance between two adjacent air guides 110 in the plurality of air guides 110 is the first distance. The first distance increases from the side of the air outlet grille 108 near the fan assembly 112 to the side of the air outlet grille 108 near the first housing 106.

[0121] In some embodiments, the distance between two adjacent air guides 110 is a first distance. This first distance increases from the side of the air outlet grille 108 near the fan assembly 112 to the side of the air outlet grille 108 near the first housing 106, thereby adjusting the distance between the air guides 110. The gradual increase in the first distance from the side of the air outlet grille 108 near the fan assembly 112 to the side near the first housing 106 reduces airflow resistance at the air outlet 154, allowing the airflow to gradually diffuse as it exits the air outlet 154, preventing excessively concentrated airflow and resulting in excessively high local pressure. The gradual diffusion of airflow and reduced resistance improve air delivery efficiency, enabling the purifier 100 to circulate indoor air more quickly, achieving a purification effect. Smooth airflow reduces noise generation and lowers energy consumption.

[0122] Specifically, in Figure 2, F represents the first distance.

[0123] Specifically, each of the multiple air guide sections 110 extends in a ring shape, and the multiple air guide sections 110 are arranged radially along the fan assembly 112, making the air outlet grille 108 a circular grid shape. The height of the entire grid is also higher on the inside and lower on the outside, conforming to the sloping shape of the first support 134. 1. The arc shape of the air outlet grille 108, with its higher inside and lower outside, matches the arc shape of the second housing 144, forming a complete air outlet 154 guide layer. This creates an air outlet area that is smaller on the inside and larger on the outside, with the opening gradually increasing. This is more conducive to the diffusion of airflow at the air outlet 154. The smoother the curve transition, the more gentle the airflow, and the softer the blowing. 2. The height of the air outlet grille 108, with its higher inside and lower outside, allows the airflow to diffuse in all directions. The higher inside and lower outside shape is more conducive to squeezing the airflow from the higher inside to the lower outside, which is more conducive to the outward diffusion of the airflow. 3. Each of the multiple air guides 110 extends in a ring shape, and the multiple air guides 110 are arranged radially along the fan assembly 112, so that the rings of circular grilles divide the airflow into a ring shape, reducing the airflow speed in the air outlet 154 area after being accelerated by the impeller 118, so that it can overflow more smoothly.

[0124] Specifically, the gradually decreasing height of the air outlet grille 108 from the inside out diffuses the segmented airflow outwards, while also matching the overall cylindrical shape of the purifier 100 in appearance.

[0125] Specifically, the curved ribs of the air outlet grille 108 and the curved surface of the second housing 144 serve as air guides, ensuring smooth airflow at the air outlet 154 and improving performance. The inner high and outer low curved shape of the air outlet grille 108 matches the curved shape of the second housing 144, forming a complete air outlet 154 air guide layer. At the same time, the inner side of the air outlet grille 108 is narrow and gradually widens on the outer side, ensuring that the airflow spreads more evenly in all directions during the blowing process. The curvature of the second housing 144 becomes smoother from the inside to the outside, eventually transitioning to an almost horizontal trend, ensuring that the airflow blows outward in an almost horizontal direction during the outward diffusion process. This completes the transformation of the airflow blown vertically from the air outlet grille 108 into a horizontal airflow, turning the purifier 100 into a fan-like product that can blow air in all directions.

[0126] Specifically, the first bracket 134 is a motor bracket. As the most important load-bearing component of the purifier 100, it houses the motor 114. The outer guide vane 142 adopts an inclined design, and the height of the outer ring of the guide vane 142 is lower than the height of the inner ring.

[0127] Specifically, the purifier 100 also includes a base 162, which is connected to the shell assembly 102 and located on the side of the shell assembly 102 away from the fan assembly 112. The base 162 serves as the base of the purifier 100 and can support the entire weight of the purifier 100.

[0128] As shown in Figure 1, an air purifier 100 is provided in one embodiment of this application, including a housing assembly 102 and a fan assembly 112. The housing assembly 102 is provided with an air inlet 152 and an air outlet 154; the fan assembly 112 is installed on the housing assembly 102, and the fan assembly 112 includes a fan wheel 118, a motor 114 and a first bracket 134. The first bracket 134 is provided with a first mounting cavity 158, and the motor 114 is connected to the fan wheel 118 and is disposed in the first mounting cavity 158; wherein, the air outlet 154 is located at the top of the air duct 156 of the fan assembly 112, and is closer to the air inlet 152 than the first mounting cavity 158.

[0129] In some embodiments, the purifier 100 includes a housing assembly 102 and a fan assembly 112. The housing assembly 102 is provided with an air inlet 152 and an air outlet 154, allowing the purifier 100 to absorb outside air through the air inlet 152 and discharge purified air through the air outlet 154, thereby achieving airflow. The fan assembly 112 is mounted on the housing assembly 102 to facilitate the installation of the fan assembly 112. The fan assembly 112 includes a fan wheel 118, a motor 114, and a first bracket 134. The first bracket 134 is provided with a first mounting cavity 158, and the motor 114 is connected to the fan wheel 118, allowing the motor 114 to drive the fan wheel 118 to rotate, thereby generating airflow. The motor 114 is disposed within the first mounting cavity 158, which provides a certain degree of protection for the motor 114, reducing the possibility of it being subjected to external impacts or damage. The air outlet 154 is located at the top of the air duct 156 of the fan assembly 112 and is closer to the air inlet 152 than the first mounting cavity 158. This allows for a positional adjustment of the air outlet 154, lowering its position so that it is directly located at the top of the air duct 156. This makes the airflow path more direct and reduces the airflow path within the purifier 100. By placing the air outlet 154 at the top of the air duct 156 of the fan assembly 112 and closer to the air inlet 152 than the first mounting cavity 158, this application shortens the airflow path within the purifier 100. Due to the shortened path of the air duct 156, the resistance encountered by the air during flow is correspondingly reduced. The reduced air resistance allows the fan assembly 112 to easily drive airflow, improving the air purification speed and efficiency of the purifier 100, thereby enhancing the performance of the purifier 100.

[0130] Specifically, the air outlet 154 is located at the top of the air duct 156 of the fan assembly 112 and is closer to the air inlet 152 than the first mounting cavity 158. That is, the position of the air outlet 154 is lower than the electrical compartment or the position of the air outlet 154 is flush with the position of the electrical compartment, or the position of the air outlet 154 is lower than the top wall of the first mounting cavity 158 or the position of the air outlet 154 is flush with the top wall of the first mounting cavity 158.

[0131] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0132] As shown in Figure 1, the housing assembly 102 includes an air inlet grille 104, a first housing 106, and an air outlet grille 108. The air inlet grille 104 is provided with an air inlet 152; the first housing 106 is connected to the air inlet grille 104; the air outlet grille 108 is located on the side of the first housing 106 away from the air inlet grille 104, and the air outlet grille 108 is provided with an air outlet 154.

[0133] In some embodiments, the housing assembly 102 includes an air inlet grille 104, a first housing 106, and an air outlet grille 108. The air inlet grille 104 is provided with an air inlet 152 for arranging the air inlet 152 to introduce air to be purified. The first housing 106 is connected to the air inlet grille 104 for installation. The air outlet grille 108 is located on the side of the first housing 106 away from the air inlet grille 104, and is provided with an air outlet 154, allowing air to flow smoothly from the air inlet 152, be accelerated and purified by the fan assembly 112, and finally be discharged from the air outlet 154. The position of the air outlet 154 is flush with the installation position of the fan assembly 112, greatly reducing the path of the air duct 156, avoiding unnecessary bends and obstructions, and correspondingly reducing the resistance encountered by the air during flow. The reduced wind resistance allows the fan assembly 112 to work more efficiently, improving the air purification speed and efficiency of the purifier 100, reducing energy consumption, and extending the service life of the purifier 100.

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

[0135] As shown in Figure 1, the air outlet grille 108 includes a plurality of ribs 178; the plurality of ribs 178 are arranged in a ring shape, and the height of the ribs 178 closer to the axis of the fan assembly 112 is higher than that of the ribs 178 farther from the axis of the fan assembly 112; or each of the plurality of ribs 178 extends radially along the fan assembly 112, and the end of the rib 178 closer to the axis of the fan assembly 112 is higher than the end of the rib 178 farther from the axis of the fan assembly 112.

[0136] In some embodiments, the rib 178 includes a plurality of air guides 110; the plurality of air guides 110 are arranged in a ring, and the height of the air guides 110 near the axis of the fan assembly 112 is higher than that of the air guides 110 away from the axis of the fan assembly 112, thereby making the rib 178 inclined. Each of the plurality of air guides 110 extends radially along the fan assembly 112, and the end of the air guide 110 near the axis of the fan assembly 112 is higher than the end of the air guide 110 away from the axis of the fan assembly 112, thereby achieving the inclined arrangement of the rib 178. By setting the downwardly inclined rib 178, the projected area of ​​the rib 178 in the horizontal direction is increased, thereby increasing the air outlet area. The increased air outlet area means that air can pass through the purifier 100 more quickly, thereby improving the air purification efficiency. Furthermore, by setting the downward-sloping ribs 178, compared to the upward-sloping method, the distance between the ribs 178 and the guide vanes 142 can be reduced or kept constant. This allows the downward-sloping ribs 178 and the guide vanes 142 to work together to guide the air out at a certain angle, making the exhaust air distribution more uniform.

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

[0138] As shown in Figures 1 and 4, the fan assembly 112 also includes a plurality of guide vanes 142, which are arranged circumferentially along the first support 134. In the height direction of the purifier 100, the guide vanes 142 are arranged downwardly from the side connected to the first support 134 to the side of the guide vanes 142 near the first housing 106.

[0139] In some embodiments, multiple guide vanes 142 are arranged circumferentially along the first bracket 134 to achieve installation of the multiple guide vanes 142. In the height direction of the purifier 100, the guide vanes 142 are arranged at an angle from the side connected to the first bracket 134 to the side of the guide vanes 142 near the first housing 106, allowing the multiple guide vanes 142 to form an inclined surface. The inclined surface formed by the guide vanes 142 has a larger area than a horizontal straight surface, directly increasing the effective area of ​​the air outlet 154, allowing air to flow out of the purifier 100 more smoothly. The increased area of ​​the air outlet 154 and the optimized airflow distribution allow air to pass through the purifier 100 more quickly and be distributed more evenly in the indoor space. Under the same conditions, the larger the air outlet area of ​​the air outlet grille 108, the better the performance of the purifier 100 generally is. The inner-high, outer-low shape of the guide vanes 142 is more conducive to squeezing airflow from the inner high point to the lower point, and is more conducive to the outward diffusion of airflow.

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

[0141] As shown in Figures 4 and 5, the guide vanes 142 are arranged at an angle in the circumferential direction of the first support 134.

[0142] In some embodiments, guide vanes 142 are arranged at an angle in the circumferential direction of the first support 134, so that multiple guide vanes 142 are arranged in the circumferential direction of the first support 134, which can guide the airflow toward the position of the air outlet grille 108, so that the air can flow out of the purifier 100 more smoothly. When the guide vanes 142 are arranged at an angle in both the height direction of the purifier 100 and the circumferential direction of the first support 134, the guide vanes 142 can be arranged at an angle in both directions, which can more flexibly adjust the direction and speed of the airflow. This not only increases the area of ​​the air outlet 154, but also allows the air to pass through the purifier 100 more quickly, so that the air can be discharged more smoothly.

[0143] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0144] As shown in Figures 1 and 4, in the height direction of the purifier 100, the distance between the air outlet grille 108 and the guide vane 142 is the second distance, which increases from the inner peripheral edge of the air outlet grille 108 to the outer peripheral edge of the air outlet grille 108.

[0145] In some embodiments, the distance between the air outlet grille 108 and the guide vane 142 in the height direction of the purifier 100 is a second distance. This second distance increases from the inner peripheral edge of the air outlet grille 108 to the outer peripheral edge of the air outlet grille 108, thereby adjusting the distance between the air outlet grille 108 and the guide vane 142, making the structure of the purifier 100 more compact. By adjusting the distance between the air outlet grille 108 and the guide vane 142, air resistance during airflow can be reduced, and the length of the air duct 156 can be shortened. By increasing the distance between the outer peripheral edge of the air outlet grille 108 and the guide vane 142, the airflow at the outer peripheral edge of the air outlet grille 108 is greater, which reduces the noise generated by the airflow impacting the air outlet grille 108, thus solving the problem of excessive airflow noise in the purifier 100.

[0146] This embodiment provides a purifier 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0147] As shown in Figure 1, in the height direction of the purifier 100, the first bracket 134 is provided with an upwardly protruding mounting part 140, and the mounting part 140 is provided with a first mounting cavity 158.

[0148] In some embodiments, in the height direction of the purifier 100, the first bracket 134 is provided with a mounting portion 140 protruding upward away from the first housing 106, and a first mounting cavity 158 is provided within the mounting portion 140; the motor 114 is disposed within the first mounting cavity 158. The mounting portion 140 can effectively fix the position of the motor 114, ensuring that it will not shake or shift during operation. The mounting portion 140 and the first mounting cavity 158 can provide a certain degree of protection for the motor 114, reducing the possibility of it being subjected to external impacts or damage. Because the motor 114 is stably supported and protected, its operation is more stable and reliable, thereby improving the overall purification efficiency of the purifier 100.
