DETAILED DESCRIPTION

[0047] In order to more clearly understand the above-mentioned purpose, 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 in the embodiments can be combined with each other without conflict.

[0048] 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 protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0049] Refer to the following Figures 1 to 10 A purifier 100 according to some embodiments of the present invention is described.

[0050] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, a purifier 100 is provided, including a shell assembly 102, a fan assembly 112 and an electric control assembly 120. The shell assembly 102 is provided with an air inlet 152 and an air outlet 154; the fan assembly 112 is arranged inside the shell assembly 102, and the air duct 156 of the fan assembly 112 is connected to the air outlet 154; the electric control assembly 120 is arranged on the top of the fan assembly 112; wherein, in the height direction of the 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 electric control assembly 120.

[0051] In this embodiment, the purifier 100 includes a shell assembly 102, a fan assembly 112 and an electronic control assembly 120. The shell assembly 102 is provided with an air inlet 152 and an air outlet 154, so that the purifier 100 can absorb the outside air through the air inlet 152, and discharge the purified air through the air outlet 154 to achieve the circulation of air flow. The fan assembly 112 is arranged inside the shell assembly 102 to achieve the installation of the fan assembly 112, so that the shell assembly 102 can protect the fan assembly 112. The air duct 156 of the fan assembly 112 is connected to the air outlet 154. When the fan assembly 112 is running, it can generate airflow, so that the outside air can be continuously sucked into the purifier 100, thereby entering the air duct 156, and the fan assembly 112 can also drive the purified air to be discharged through the air outlet 154. The electric control assembly 120 is arranged at the top of the fan assembly 112 to realize the installation and fixation of the electric control assembly 120, and the electric control assembly 120 can control 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 is closer to the air inlet 152 relative to the electric control assembly 120, so as to adjust the position of the air outlet 154. The position of the air outlet 154 is moved down and directly located at the top of the air duct 156, so that the air flow path is more direct, and the air flow path inside the purifier 100 is reduced. The present application shortens the air flow path in the purifier 100 by arranging the air outlet 154 at the top of the air duct 156 of the fan assembly 112 and below the electric control assembly 120. Due to the shortening of the air duct 156 path, the resistance encountered by the air during the flow process is also reduced accordingly. The reduction in wind resistance enables the fan assembly 112 to easily drive air flow, thereby increasing the air purification speed and efficiency of the purifier 100 , thereby improving the performance of the purifier 100 .

[0052] Specifically, the present application sets the air outlet 154 at the top of the air duct 156 of the fan assembly 112 and below the electric control assembly 120, so that the purifier 100 can discharge air below the electric control assembly 120, retaining the placement space of the power board 130 and the main control board, and setting the air outlet 154 at a position substantially flush with the installation position of the motor 114 through the side opening, greatly compressing the air duct 156 space and reducing wind resistance. Under the same volume of the purifier 100, the performance of the purifier 100 can be improved by shortening the path of the air duct 156.

[0053] Specifically, in Figure 1 , arrow A indicates the height direction of the purifier 100 .

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

[0055] like Figure 1 As shown, the shell assembly 102 includes an air inlet grille 104, a first shell 106 and an air outlet grille 108. The air inlet grille 104 is provided with an air inlet 152; the first shell 106 is connected to the air inlet grille 104; the air outlet grille 108 is provided on a side of the first shell 106 away from the air inlet grille 104, and the air outlet grille 108 is provided with an air outlet 154.

[0056] In this embodiment, the shell assembly 102 includes an air inlet grille 104, a first shell 106 and an air outlet grille 108. The air inlet grille 104 is provided with an air inlet 152 to realize the arrangement of the air inlet 152, and the air to be purified can be introduced. The first shell 106 is connected to the air inlet grille 104 to realize the installation of the first shell 106. The air outlet grille 108 is arranged on the side of the first shell 106 away from the air inlet grille 104, and the air outlet grille 108 is provided with an air outlet 154, so that air can flow in 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, which greatly reduces the path of the air duct 156, avoids unnecessary bending and obstruction, and the resistance encountered by the air during the flow is also reduced accordingly. The reduction in wind resistance enables the fan assembly 112 to work more efficiently, thereby improving the air purification speed and efficiency of the purifier 100, reducing energy consumption, and extending the service life of the purifier 100.

[0057] Specifically, the first shell 106 is in a ring shape and serves as an outer shell of the purifier 100 .

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

[0059] like Figure 1 , Figure 3 and Figure 4 As shown, the air outlet grille 108 includes a plurality of air guide portions 110; the plurality of air guide portions 110 are arranged in a ring shape, and the height of the air guide portion 110 among the plurality of air guide portions 110 close to the axis of the fan assembly 112 is higher than the height of the air guide portion 110 among the plurality of air guide portions 110 far from the axis of the fan assembly 112; or each air guide portion 110 among the plurality of air guide portions 110 extends radially along the fan assembly 112, and one end of the air guide portion 110 close to the axis of the fan assembly 112 is higher than the end of the air guide portion 110 far from the axis of the fan assembly 112.

[0060] In this embodiment, the air outlet grille 108 includes a plurality of air guides 110; the plurality of air guides 110 are arranged in a ring shape, and the height of the air guide 110 close to the axis of the fan assembly 112 among the plurality of air guides 110 is higher than the height of the air guide 110 far from the axis of the fan assembly 112 among the plurality of air guides 110, so that the air outlet grille 108 is arranged obliquely. Each of the plurality of air guides 110 extends radially along the fan assembly 112, and one end of the air guide 110 close to the axis of the fan assembly 112 is higher than one end of the air guide 110 far from the axis of the fan assembly 112, so as to realize the oblique arrangement of the air outlet grille 108. By setting the air outlet grille 108 inclined downward, the projection area of ​​the air outlet grille 108 in the horizontal direction is increased, so that the air outlet area can be increased. The increase in the air outlet area means that the air can pass through the purifier 100 more quickly, thereby improving the air purification efficiency. Furthermore, by providing an air outlet grille 108 that is inclined downward, the distance between the air outlet grille 108 and the guide vane 142 can be reduced or remain unchanged compared to the upward inclined manner, so that the air outlet grille 108 that is inclined downward cooperates with the guide vane 142 to guide the air to flow out at a certain angle, so that the exhaust air is more evenly distributed.

[0061] Specifically, in Figure 1 , arrow H indicates the axis of the fan assembly 112 .

[0062] Specifically, in Figure 3 In FIG. 1 , arrow I indicates the height direction of the air guide portion 110 .

[0063] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0064] like Figure 1 , Figure 5 and Figure 6 As shown, the fan assembly 112 includes a first bracket 134 and a plurality of guide vanes 142. The plurality of guide vanes 142 are arranged along the circumference of the first bracket 134, and in the height direction of the purifier 100, the side where the guide vanes 142 are connected to the first bracket 134 to the side where the guide vanes 142 are close to the first housing 106 are arranged to be inclined downward.

[0065] In this embodiment, the fan assembly 112 includes a first bracket 134 and a plurality of guide vanes 142. The plurality of guide vanes 142 are arranged along the circumference of the first bracket 134 to achieve the installation of the plurality of guide vanes 142. In the height direction of the purifier 100, the side where the guide vane 142 is connected to the first bracket 134 is arranged to be tilted downward to the side where the guide vane 142 is close to the first shell 106, so that the plurality of guide vanes 142 can form an inclined surface, and the inclined surface formed by the guide vane 142 is larger than the area of ​​the horizontal straight surface, which directly increases the effective area of ​​the air outlet 154, so that the air can flow out of the purifier 100 more smoothly. The increase in the area of ​​the air outlet 154 and the optimization of the air flow distribution enable the air to pass through the purifier 100 more quickly and be more evenly distributed 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 is generally. The guide vane 142 having a high inner side and a low outer side is more conducive to squeezing the airflow from the inner high side to the lower side, and is more conducive to the outward diffusion of the airflow.

[0066] Specifically, the inclined surface formed by the plurality of guide vanes 142 is larger than the horizontal straight surface, which directly increases the area of ​​the air outlet 154, so that the air outlet area of ​​the corresponding air outlet grille 108 is also increased accordingly. 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 will increase the overall height of the air duct 156 system, that is, Figure 1 As the size of D increases, the multiple guide vanes 142 in the present application form a sloped shape that is higher inside and lower outside, which reduces unnecessary height of the air duct 156, further compresses the size of the air duct 156, and reduces the wind resistance of the airflow inside the air duct 156 on the side; at the same time, when the size of D is reduced, the upper part of the purifier 100 will appear smaller in appearance; in the manner of the multiple guide vanes 142 in the present application, the airflow is diffused to the surroundings, and the guide vanes 142 that are higher inside and lower outside are more conducive to squeezing the airflow from the high inside to the low inside, and are more conducive to the outward diffusion of the airflow.

[0067] Specifically, in Figure 1 , D represents the length of the air duct 156 .

[0068] Specifically, in Figure 5 , arrow B indicates the circumferential direction of the first bracket 134 .

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

[0070] like Figure 4 and Figure 5 As shown, the guide vanes 142 are arranged obliquely in the circumferential direction of the first bracket 134 .

[0071] In this embodiment, the guide vanes 142 are arranged obliquely in the circumferential direction of the first bracket 134, so that the arrangement of multiple guide vanes 142 in the circumferential direction of the first bracket 134 can guide the airflow to flow to 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 obliquely in both the height direction of the purifier 100 and the circumferential direction of the first bracket 134, the guide vanes 142 can be arranged obliquely in both directions, and the flow direction and speed of the airflow can be adjusted more flexibly, which can not only increase the area of ​​the air outlet 154, but also allow the air to pass through the purifier 100 more quickly, so that the air can be discharged more smoothly.

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

[0073] like Figure 4 As shown, in the height direction of the purifier 100 , the distance between the air outlet grille 108 and the guide vane 142 is a second distance, and the 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 .

[0074] In this embodiment, 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, and the 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, so as to adjust the distance between the air outlet grille 108 and the guide vane 142, so that the structure of the purifier 100 is more compact. By adjusting the distance between the air outlet grille 108 and the guide vane 142, the resistance of the air in the flow process 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 noise generated by the airflow hitting the air outlet grille 108 can be reduced due to the larger air volume at the outer peripheral edge of the air outlet grille 108, thereby solving the problem of large air outlet noise of the purifier 100.

[0075] Specifically, in Figure 4 In , G represents the second distance.

[0076] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0077] like Figure 1 , Figure 5 and Figure 6 As shown, 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 in the mounting portion 140 ; ​​the fan assembly 112 includes a motor 114 , and the motor 114 is provided in the first mounting cavity 158 .

[0078] In this embodiment, 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 in the mounting portion 140; the fan assembly 112 includes a motor 114, and the motor 114 is arranged in the first mounting cavity 158. The mounting portion 140 can effectively fix the position of the motor 114 to ensure that it does not shake or shift during operation. The mounting portion 140 and the first mounting cavity 158 can provide a certain protection for the motor 114, reducing the possibility of it being impacted or damaged by the outside world. Since 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.

[0079] Specifically, the motor 114 is a power component of the purifier 100 , the power core of the entire machine, and is assembled in the middle area of ​​the first bracket 134 .

[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] like Figure 1 As shown, the fan assembly 112 further includes a volute 116 and a wind wheel 118. The volute 116 is connected to the first housing 106 and is located inside the first housing 106; the wind wheel 118 is connected to the motor 114 and is located inside the volute 116, and an air duct 156 is provided between the wind wheel 118 and the interior of the volute 116.

[0111] like Figure 1 and Figure 4 As shown, in the radial direction of the fan assembly 112 , the curvature of the wind guide surface 150 decreases from the side of the wind guide surface 150 close to the fan assembly 112 to the side of the wind guide surface 150 close to the first housing 106 .

[0112] In this embodiment, 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 close to the fan assembly 112 to the side of the air guide surface 150 close to the first shell 106, so as to adjust the air guide surface 150, so that the wind blown out vertically from the air outlet grille 108 can be effectively diverted into horizontal wind, so that the air supply range of the purifier 100 is wider. Horizontal air supply helps to enhance indoor air circulation, so that the purifier 100 can purify the indoor air more quickly and evenly distribute it to every corner, thereby improving the purification efficiency. The arc of the second shell 144 transitions from the inside to the outside, and the curvature transitions more and more smoothly, and finally gradually transitions to a trend that is approximately horizontal, ensuring that the airflow is blown out in an approximately horizontal direction during the process of outward diffusion, completing the diversion of the wind blown out vertically from the air outlet grille 108 into horizontal wind, and transforming the purifier 100 into a product similar to a fan that can blow air in all directions. Horizontal air supply allows users to experience a more comfortable and uniform air supply effect, avoiding the discomfort that may be caused by vertical air supply, thereby improving the user experience.

[0120] Specifically, the seat body 124 is the lower cover of the power box 122 , and the box body 126 is the upper cover of the power box 122 .

[0121] Specifically, Figure 5 and Figure 6 As shown, the structure of the first bracket 134 is mainly divided into two parts, the lower part is mainly used to install the motor 114, and the middle groove, that is, the mounting portion 140 is a groove, and the groove has a first mounting cavity 158 for accommodating the power pack part of the motor 114.

[0128] Specifically, Figure 3 As shown, a first buckle position 166 is provided on the first bracket 134, and a plurality of first buckle positions 166 are arranged circumferentially along the outer circle of the first bracket 134; a second buckle position 168 is provided on the air outlet grille 108, and a plurality of second buckle positions 168 are arranged circumferentially along the outer circle of the air outlet grille 108; the first buckle position 166 and the second buckle position 168 can be snap-fitted, that is, the first bracket 134 and the air outlet grille 108 form a snap-fit ​​on the outer circle, and the air outlet grille 108 is fixed to the outer circle of the first bracket 134 by snap-fitting.

[0129] Specifically, Figure 7 , Figure 8 and Fig. 9As shown, the power box 122 includes a box body 126 and a base body 124, and the first bracket 134 is provided with three first screw columns 136 and three second screw columns 138, wherein the three first screw columns 136 cover the base body 124 to prevent the base body 124 from moving.

[0130] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0131] like Figure 1 , Figure 3 and Figure 4 As shown, in the radial direction of the fan assembly 112 , the air outlet grille 108 extends in an arc shape from a side close to the fan assembly 112 to a side of the air outlet grille 108 close to the first housing 106 .

[0132] In this embodiment, in the radial direction of the fan assembly 112, the air outlet grille 108 extends in an arc shape from the side close to the fan assembly 112 to the side of the air outlet grille 108 close to the first housing 106. The arc-shaped extended air outlet grille 108 can effectively guide the airflow blown out from the fan assembly 112, so that it flows out of the air outlet 154 more smoothly, reducing the residence time of the airflow inside the purifier 100, making the airflow distribution more uniform, thereby improving the purification efficiency. Through the arc-shaped extension design, the air outlet grille 108 can make the airflow blow out in a softer and more uniform manner, avoiding the situation where the local airflow is too strong or too weak, thereby optimizing the air supply effect and improving the user experience.

[0133] Specifically, the top cover 160 may be load-bearing, so that a user may place items on the top cover 160 .

[0134] Specifically, the top cover 160 is in a flat form, which is convenient for users to place items or decorate other ornaments.

[0135] Specifically, the top of the second shell 144 can support the top cover 160, and the lower end of the second shell 144 is connected to the air outlet grille 108, playing a role of connecting the upper and lower parts. At the same time, the outer surface of the second shell 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.

[0136] 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 circle of arc surface, with an inclined arc transition from high inside to low outside, which is beneficial to the guidance of airflow.

[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] like Figure 1 and Figure 2 As shown, the air outlet grille 108 includes a plurality of air guide portions 110 , each of which extends in a ring shape, and the plurality of air guide portions 110 are arranged radially along the fan assembly 112 , and an air outlet 154 is formed between two adjacent air guide portions 110 among the plurality of air guide portions 110 .

[0139] In this embodiment, the air outlet grille 108 includes a plurality of air guides 110, each of which extends in a ring shape, and the plurality of air guides 110 are arranged along the radial direction of the fan assembly 112 to achieve the installation of the air guide 110. An air outlet 154 is formed between two adjacent air guides 110 in the plurality of air guides 110, so that the purifier 100 can discharge the purified air. The plurality of air guides 110 are arranged along the radial direction of the fan assembly 112 to form a plurality of air outlets 154, so that the airflow that has just been accelerated by the wind wheel 118 is buffered in the air outlet 154 area, reducing the wind speed, so that the airflow can be relatively smoothly overflowed from the air outlet 154. After being buffered and dispersed by the air guide 110, the airflow becomes softer and more uniform, which improves the user's comfort.

[0140] Specifically, in Figure 1 In FIG. 1 , arrow E indicates the radial direction of the fan assembly 112 .

[0141] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0142] like Figure 2 As shown, the distance between two adjacent air guides 110 among the plurality of air guides 110 is a first distance, and the first distance increases from a side of the air outlet grille 108 close to the fan assembly 112 to a side of the air outlet grille 108 close to the first shell 106 .

[0143] In this embodiment, the distance between two adjacent air guides 110 among the multiple air guides 110 is a first distance, and the first distance increases from the side of the air outlet grille 108 close to the fan assembly 112 to the side of the air outlet grille 108 close to the first shell 106, so as to adjust the distance between the air guides 110. The first distance gradually increases from the side of the air outlet grille 108 close to the fan assembly 112 to the side close to the first shell 106, thereby reducing the resistance of the airflow at the air outlet 154, so that the airflow can gradually diffuse when flowing out of the air outlet 154, avoiding excessive local pressure caused by excessive concentration of airflow. The gradual diffusion of airflow and the reduction of resistance improve the air supply efficiency, and the purifier 100 can circulate the indoor air faster to achieve a purification effect. The smooth outflow of airflow reduces the generation of noise and reduces energy consumption.

[0144] Specifically, in Figure 2 In the figure, F represents the first distance.

[0145] Specifically, each of the multiple air guides 110 extends in a ring shape, and the multiple air guides 110 are arranged along the radial direction of the fan assembly 112, so that the air outlet grille 108 is a circular grid shape, and the height of the entire grid is also high inside and low outside, which fits the slope shape of the first bracket 134. 1. The arc shape of the air outlet grille 108, which is high inside and low outside, matches the arc shape of the second shell 144, forming a complete air outlet 154 guide layer, forming an air outlet area that is small inside and large outside, and the opening gradually increases, which is more conducive to the diffusion of the airflow of the air outlet 154. The smoother the curve transition, the more relaxed the airflow, and the softer the blowing. 2. The height of the air outlet grille 108, which is high inside and low outside, is that the airflow diffuses to the surroundings. The high inside and low outside shape is more conducive to squeezing the airflow from the high inside to the low inside, and is more conducive to the outward diffusion of the airflow. 3. Each of the multiple air guide portions 110 extends in a ring shape, and the multiple air guide portions 110 are arranged along the radial direction of the fan assembly 112, so that the circles of circular grilles divide the overall airflow into a ring shape, and the airflow that has just been accelerated by the wind wheel 118 is reduced in speed in the air outlet 154 area, so that it can overflow more smoothly.

[0146] Specifically, the height of the air outlet grille 108 gradually decreases from the inside to the outside, which diffuses the divided airflow outward, while also conforming to the cylindrical shape of the purifier 100 in appearance.

[0147] Specifically, the arc-shaped ribs of the air outlet grille 108 and the arc-shaped exterior surface of the second shell 144 play a role in guiding airflow, ensuring the smooth flow of airflow at the air outlet 154 and promoting performance improvement. The high-inside-low-outside arc shape of the air outlet grille 108 matches the arc-shaped shape of the second shell 144, forming a complete air outlet 154 guide layer. At the same time, the inner side of the air outlet grille 108 is narrow, and the outer side gradually widens, ensuring that the airflow spreads more evenly to the surroundings during the blowing process; the arc of the second shell 144 transitions from the inside to the outside, and the curvature transitions more and more smoothly, and finally gradually transitions to an approximately horizontal trend, ensuring that the airflow is blown out in an approximately horizontal direction during the outward diffusion process, completing the diversion of the wind blown vertically from the air outlet grille 108 into horizontal wind, and transforming the purifier 100 into a product similar to a fan that can blow air in all directions.

[0148] Specifically, the first bracket 134 is a motor bracket, which is the most important load-bearing component of the purifier 100. The motor 114 is installed inside. The guide vanes 142 of the outer ring are inclined, and the outer ring height of the guide vanes 142 is lower than the inner ring height.

[0149] Specifically, the purifier 100 further includes a base 162 , which is connected to the shell assembly 102 and is located on a side of the shell assembly 102 away from the fan assembly 112 . The base 162 serves as a base of the purifier 100 and can support the entire load-bearing capacity of the purifier 100 .

[0150] like Figure 1 As shown, in one embodiment of the present application, a purifier 100 is provided, including a shell assembly 102 and a fan assembly 112. The shell assembly 102 is provided with an air inlet 152 and an air outlet 154; the fan assembly 112 is installed on the shell assembly 102, and the fan assembly 112 includes a wind wheel 118, a motor 114 and a first bracket 134, and the first bracket 134 is provided with a first installation cavity 158, and the motor 114 is connected to the wind wheel 118, and the motor 114 is arranged in the first installation 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 installation cavity 158.

[0151] In this embodiment, the purifier 100 includes a shell assembly 102 and a fan assembly 112. The shell assembly 102 is provided with an air inlet 152 and an air outlet 154, so that the purifier 100 can absorb the outside air through the air inlet 152, and discharge the purified air through the air outlet 154 to achieve the circulation of airflow. The fan assembly 112 is installed on the shell assembly 102 to achieve the installation of the fan assembly 112. The fan assembly 112 includes a wind 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 wind wheel 118, so that the motor 114 can drive the wind wheel 118 to rotate, thereby generating airflow. The motor 114 is arranged in the first mounting cavity 158, and the first mounting cavity 158 can provide a certain protection for the motor 114, reducing the possibility of it being impacted or damaged by the outside. 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 relative to the first installation cavity 158, so as to adjust the position of the air outlet 154. The air outlet 154 is moved down and directly located at the top of the air duct 156, so that the air flow path is more direct, and the air flow path inside the purifier 100 is reduced. The present application shortens the air flow path in the purifier 100 by setting the air outlet 154 at the top of the air duct 156 of the fan assembly 112, and closer to the air inlet 152 relative to the first installation cavity 158. Due to the shortening of the air duct 156 path, the resistance encountered by the air during the flow process is also reduced accordingly. The reduction of wind resistance enables the fan assembly 112 to easily drive the air flow, improves the air purification speed and efficiency of the purifier 100, and thus improves the performance of the purifier 100.

[0152] 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 relative to the first installation cavity 158, that is, the position of the air outlet 154 is lower than the electrical room or the position of the air outlet 154 is flush with the position of the electrical room, or, the position of the air outlet 154 is lower than the top wall of the first installation cavity 158 or the position of the air outlet 154 is flush with the top wall of the first installation cavity 158.

[0153] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0154] like Figure 1 As shown, the shell assembly 102 includes an air inlet grille 104, a first shell 106 and an air outlet grille 108. The air inlet grille 104 is provided with an air inlet 152; the first shell 106 is connected to the air inlet grille 104; the air outlet grille 108 is provided on a side of the first shell 106 away from the air inlet grille 104, and the air outlet grille 108 is provided with an air outlet 154.

[0155] In this embodiment, the shell assembly 102 includes an air inlet grille 104, a first shell 106 and an air outlet grille 108. The air inlet grille 104 is provided with an air inlet 152 to realize the arrangement of the air inlet 152, and the air to be purified can be introduced. The first shell 106 is connected to the air inlet grille 104 to realize the installation of the first shell 106. The air outlet grille 108 is arranged on the side of the first shell 106 away from the air inlet grille 104, and the air outlet grille 108 is provided with an air outlet 154, so that air can flow in 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, which greatly reduces the path of the air duct 156, avoids unnecessary bending and obstruction, and the resistance encountered by the air during the flow is also reduced accordingly. The reduction in wind resistance enables the fan assembly 112 to work more efficiently, thereby improving the air purification speed and efficiency of the purifier 100, reducing energy consumption, and extending the service life of the purifier 100.

[0156] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0157] like Figure 1 As shown, 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 among the plurality of ribs 178 close to the axis of the fan assembly 112 is higher than the height of the ribs 178 among the plurality of ribs 178 far from the axis of the fan assembly 112; or each rib 178 among the plurality of ribs 178 extends radially along the fan assembly 112, and one end of the rib 178 close to the axis of the fan assembly 112 is higher than the end of the rib 178 far from the axis of the fan assembly 112.

[0158] In this embodiment, the rib 178 includes a plurality of air guides 110; the plurality of air guides 110 are arranged in a ring shape, and the height of the air guide 110 close to the axis of the fan assembly 112 among the plurality of air guides 110 is higher than the height of the air guide 110 far from the axis of the fan assembly 112 among the plurality of air guides 110, so that the rib 178 is arranged obliquely. Each of the plurality of air guides 110 extends radially along the fan assembly 112, and one end of the air guide 110 close to the axis of the fan assembly 112 is higher than one end of the air guide 110 far from the axis of the fan assembly 112, so as to realize the oblique arrangement of the rib 178. By setting the rib 178 inclined downward, the projection area of ​​the rib 178 in the horizontal direction is increased, so that the air outlet area can be increased. The increase in the air outlet area means that the air can pass through the purifier 100 more quickly, thereby improving the air purification efficiency. Furthermore, by providing the ribs 178 inclined downward, the distance between the ribs 178 and the guide vanes 142 can be reduced or remain unchanged compared to the upward inclined manner, so that the ribs 178 inclined downward cooperate with the guide vanes 142 to guide the air to flow out at a certain angle, so that the exhaust air is more evenly distributed.

[0159] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0160] like Figure 1 and Figure 4 As shown, the fan assembly 112 also includes a plurality of guide vanes 142, which are arranged along the circumference of the first bracket 134. In the height direction of the purifier 100, the guide vanes 142 are arranged to tilt downward from the side where the guide vanes 142 are connected to the first bracket 134 to the side where the guide vanes 142 are close to the first shell 106.

[0161] In this embodiment, a plurality of guide vanes 142 are arranged along the circumference of the first bracket 134 to achieve the installation of a plurality of guide vanes 142. In the height direction of the purifier 100, the side of the guide vane 142 connected to the first bracket 134 to the side of the guide vane 142 close to the first shell 106 is arranged downwardly tilted, so that a plurality of guide vanes 142 can form an inclined surface, and the inclined surface formed by the guide vane 142 is larger than the area of ​​the horizontal straight surface, which directly increases the effective area of ​​the air outlet 154, so that the air can flow out of the purifier 100 more smoothly. The increase in the area of ​​the air outlet 154 and the optimization of the air flow distribution enable the air to pass through the purifier 100 more quickly and be more evenly distributed 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 is generally. The guide vane 142 with high inside and low outside is more conducive to squeezing the airflow from the high inside to the low inside, and is more conducive to the outward diffusion of the airflow.

[0162] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0163] like Figure 4 and Figure 5 As shown, the guide vanes 142 are arranged obliquely in the circumferential direction of the first bracket 134 .

[0164] In this embodiment, the guide vanes 142 are arranged obliquely in the circumferential direction of the first bracket 134, so that the arrangement of multiple guide vanes 142 in the circumferential direction of the first bracket 134 can guide the airflow to flow to 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 obliquely in both the height direction of the purifier 100 and the circumferential direction of the first bracket 134, the guide vanes 142 can be arranged obliquely in both directions, and the flow direction and speed of the airflow can be adjusted more flexibly, which can not only increase the area of ​​the air outlet 154, but also allow the air to pass through the purifier 100 more quickly, so that the air can be discharged more smoothly.

[0165] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0166] like Figure 1 and Figure 4 As shown, in the height direction of the purifier 100 , the distance between the air outlet grille 108 and the guide vane 142 is a second distance, and the 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 .

[0167] In this embodiment, 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, and the 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, so as to adjust the distance between the air outlet grille 108 and the guide vane 142, so that the structure of the purifier 100 is more compact. By adjusting the distance between the air outlet grille 108 and the guide vane 142, the resistance of the air in the flow process 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 noise generated by the airflow hitting the air outlet grille 108 can be reduced due to the larger air volume at the outer peripheral edge of the air outlet grille 108, thereby solving the problem of large air outlet noise of the purifier 100.

[0168] This embodiment provides a purifier 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0169] like Figure 1As shown, in the height direction of the purifier 100 , the first bracket 134 is provided with a mounting portion 140 protruding upward, and a first mounting cavity 158 is provided in the mounting portion 140 .

[0170] In this embodiment, 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 shell 106, and a first mounting cavity 158 is provided in the mounting portion 140; the motor 114 is arranged in the first mounting cavity 158. The mounting portion 140 can effectively fix the position of the motor 114 to ensure that it does not shake or shift during operation. The mounting portion 140 and the first mounting cavity 158 can provide a certain protection for the motor 114, reducing the possibility of it being impacted or damaged by the outside world. Since 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.
